VOLUME XXXVI.
Revision of the BLASTORASID^E of North America.
BY WM. G. DIETZ, M. D. (Plates I-IV.)
The Blastobasidae as now understood and distinguished from the CEcophoridse form a well defined family of the Tineina. Although the term had been used by Mr. E. Meyrick* as far back as 1894, and since that time by Lord Walsingham,t the honor of giving the first definition of the family under consideration belongs to Mr. A. Busck.t
Its characters are as follows :
Labial palpi variable in development, often dimorphic in the sexes.
Maxillary palpi rudimentary.
Antennas shorter than the forewings ; excised above the basal joint in some (PI. II, figs. 14, 17a) {Blastobasis, Valen- tinia, Holocera in part, Euresia) , the excision being more or less filled by a scale tuft arising from the proximal end of the excision. The basal joint more or less widened into an eye cap, convex above, concave beneath with a glabrous space which covers the eye in repose ; anterior margin of joint fringed with long, more or less stiff hairs — pecten (PI. II, fig. lb), or else with a conchiloidal shield of close set, long scales (PI. I, fig. la) {Calosima, Zenodochium) .

2 AMERICAN LEPIDOPTERA.
Face smooth scaled, vertex often with coarsely appressed scales.
Forewings elongated, pointed, with twelve veins ; cell long, veins 2 to 10 crowded at its end (PI. I, figs. 1, 8; PI. II, figs. 13a, 17c), the latter sometimes a little removed from the angle, veins 7 + 8 stemmed, 7 to costa before the apex, rarely to latter; 4 + 5 stemmed in Pigritiae (except Dryo- peria) , free in Blastobases. Basal membrane thickened be- tween the distal end of vein 11 and the costal margin — the stigma of Zeller. Vein lb furcate at base.
Hindwings lanceolate to ovate, the costal margin gener- ally refuse from or somewhat before the insertion of vein 8 ; 7 or 8 veins.
Posterior tibiae roughened above with long, coarse hair.
The pattern of markings of the forewings consists in gen- eral of a patch on both margins at about one-third the wing length, frequently coalescing and forming a fascia, more or less distinct, a spot in the median space before the middle — first discal — and two spots at end of cell, second discals ; more rarely there is a spot on the posterior margin of the cell beyond the middle of wing length ; very rarely ( Calosima) the wing is devoid of all markings.
The primary stages of a large number of these insects remain thus far unknown, especially is this the case of the subfamily Pigritiae, of which we are entirely in the dark. The larvae of some Blastobases are known to live in seed vessels, while others are predaceous upon Caocids, Aphids, and possibly other larvae.
In his generic table of genera, published in 1907,* Lord Walsingham enumerates eighteen genera, six of which are foreign to our fauna. Of the remaining twelve, Endrosis has properly been referred to the CEcophoridae. Of the other eleven, four {Epigritia, Catacrypris, Cynotes, Hypatopa, syn. Hypatima) , being based on secondary sexual characters or the relation of vein 5 to 3 + 4 of hindwing, become invalid. Thus in his latest revision, published in February of the present year,* we only find enumerated ten genera. Two

of these — Tecmerium, Auximobasis — do nol occur in our fauna.
Hypatima Hb., was founded on Chelaria conscriptella Hb., a Gelechid.
Hypatopa Wish., type CEcophora inunctella Zell., and Cynotes Wish., type iceryceella Riley, were established on vein 5 of hindwing, being feer from stem of 3 + 4. This character is very variable, not only in different specimens of the same species, but even in the wings of the same individual.
Epigritia Dietz, type pallidotinctella Dietz {ochrocomella Clem.), and Catacrypsis Wish., type micella Wish., differ from Pigritia Clem., and Holcocera Clem., respectively, only in secondary sexual characters. Calinita Busck., type spon- sella Busck., is a synonym of Arotrura Wish. — Scythris Hb.
Dryope, according to Mr. Karl R. Coolidge,* preoccupied in Diptera and Crustacea, he proposes Dryoperia in its stead.
To these eight genera I have to add three new ones, making a total of eleven. They fall into two well defined and easily recognizable groups or subfamilies, as follows :
Labial palpi very small, often minute Pigritiae.
Labial palpi well developed, long, generally recurved. ..Blastobases.
Subfamily PIGRITIA.
Characterized as follows : Labial palpi short, moderate in both sexes {Ploiophora) ; very minute in the male, longer and more distinct in the female {Pigritia, Pseudopigritia) , or else very minute in both sexes {Dryoperia). Antennae not excised above the basal joint. Forewings with veins 4+5 stemmed, rarely {Dryoperia) separate. Hindwings with seven veins.
The four genera belonging here are distinguished as follows :
1. Veins 4 + 5 of forewing stemmed 2.
Veins 4 + 5 of forewing free 4. Dryoperia.
2. Vein 9 of forewing free 3.
Vein 9 of forewing and of vein 7 3. Pseudopigritia.
3. Third joint of labial palpi depressed 1. Ploiophora.
Third joint of labial palpi not depressed 2. Pigritia.

For further consideration of the genera and species of this subfamily I refer the student to my paper entitled " On Pigritia Clem.,"* but I wish to make here a correction. An examination of the type of Pigritia ochrocomella in the col- lection of the American Entomological Society at the Acad- emy of Natural Sciences of Philadelphia, subsequent to the publication of my paper, proved this to be identical with my pallidotinctella, type of Epigritia Dietz, also that heide- mannella is only a variety of ochrocomella. What had been recognized and described by me as ochrocomella — determined as such by Lord Walsingham — will hereafter be known as erratella. Of the twenty-nine species enumerated in Dr. Dyar's list, one will be reduced to a variety.
Subfamily BLASTOBASES.
Labial palpi always strongly developed, long, and gener- ally recurved. Veins 4 -f- 5 of forewing free. Hindwings with eight, more rarely (Blaslobasis, Zenodochhcm) with seven veins.
Dr. Dyar's list contains twenty-two species of this sub- family. Of these, Blastobasis subtractella Walker is a Gele- chid ; Holcocera quisquiliella Ze\l. I regard as a variety of chalcofrontella Clem. ; Hoi. nubilielta Zell. is identical with Gelechia glandulella Riley (type of Valentinia Wish.) ; Hole, friangularisella Ch. is Hoi. sciaphilella Zell. ; Hoi. fusco- pulvella Ch., no description known, leaving thus seventeen species and one variety ; Lord Walsinghamf in his paper described fourteen new species. Four of these, however (Hj'PaloPa episcia, conia, fasciata and orites) , belong to the GEcophoridse, and have been referred by Mr. A. BusckJ to the genus Borkeuhaiisia Hub. To the remaining ten have to be added two of Chambers' species brought to our notice by his lordship and omitted by Dr. Dyar in his list. This then brings the number of species heretofore described to twenty-nine and one variety. To these I have to add thirty-

seven species and ten varieties, making a total of sixty-six species and eleven varieties distributed among seven genera. The latter are distinguished as follows :
1. Hindwings with seven veins 2.
Hindwings with eight veins 3.
2. Basal joint of antennae with pecten 1. Blastobasis.
Basal joint of antennas with conchiloidal shield.. 2. Zeiiodochium.
3. Veins 3 + 4 of hindwing free 4.
Veins 3 + 4 of hindwing stemmed 3. Valeiitiuia.
4. Vein 4 of hindwing from before angle of cell 4. Euresia.
Veins 3+4 of hindwing from angle of cell 5.
5. Basal joint of antennae with pecten 6.
Basal joint of antennae with conchiloidal shield 5. Calosima.
6. Forewings without ridge of raised scales 6. Holeocera.
Forewings with such a ridge 7. Eubolepia.
BLASTOBASIS Zell.
Type phycidella Zell.
Tongue of moderate length, scaly at base. Labial palpi long, recurved, generally a little shorter and stouter in the male than in the female. Basal joint of antennae broad, con- vex, with well-marked pecten ; shaft excised above the base in the male with scale tuft in the excision ; shortly ciliate and finely denticulate beneath. Forewings more or less elongate, pointed; twelve veins, 7 + 8 stemmed, 7 to costa, remaining veins free. Hindwings with seven veins, 4 absent, 3 + 5 connate or stemmed. Hind tibiae with brush of setace- ous hairs above.
The only character which distinguishes this genus from the other genera with long labial palpi are the hindwings with seven veins only, agreeing in this with Zeiiodochium and from which it differs by the pecten of the basal joint of the antennae.
Blastobasis citricolella Ch. and coccivorella Ch. belong to Zenodochium Wish., Blastobasis umbiliella Zell., glandulella Riley, is a Valentinia. Blastobasis subtraciella Walker, is a Gelechid, Blastobasis sciaphilella TjqW.., {ractilinea 7j&\., quis- quiliella Zell., livorella 7jzYl., and fluxella (?) Zell., belong to Holeocera ; Blastobasis atdugella Zell., to Pigritia Clem.

1. B. guilaiidinre Busck.
Mr. Busck describes this species as follows : " Antennae dark fuscous, basal joint yellowish ; in the male strongly notched beyond first joint, with pecten on this joint ; shortly ciliated in its entire length ; in female simple, basal joint with pecten. Labial palpi smooth, curved, slender, dark fuscous ; tip somewhat lighter. Tongue stout, scaled at base, coiled at the end. Head and thorax yellowish fuscous; forewings dark fuscous with a somewhat lighter shade before apex and along costa. A small deep black spot on middle of cell, two similar black spots at end of cell, one above the other ; below these an indistinct blackish spot and similar indistinct blackish spots along the apical edge. Cilia yellowish fuscous. Hindwings shining, yellowish fuscous. Abdomen shining, dark fuscous ; anal tuft yellow ; underside whitish, speckled with dark fuscous. Legs yellowish with fuscous shadings on the outside ; hairs above posterior tibiae ashy yellow." Alar expanse 14 mm.
Bred from Gxdlandina handucella, collected by Dr. Dyar at Palm Beach, Florida, March 5, 1900.
I have seen the type specimens in the Nat. Mus. Coll. There is some resemblance to Holcocera chalcofrontella, var. fumerella, from which it is sufficiently removed by the vena- tion of the hindwings. The third joint of the labial palpi is very slender and nearly as long as the second.

2. B. hulstella n. sp. (Plate I, fig. 2).— Palpi long, ascending, slightly recurved, moderately thick, the terminal joint nearly the thick- ness of the preceding one, gray, the second joint without densely, the third less so, overlaid with fuscous, extreme apex of former pale. Head gray, speckled with fuscous. Antennae dark fuscous brown, a trifle paler beneath, basal joint sordid grayish-white, scarcely one-half longer than wide, pecten of stiff hairs. Thorax gray, speckled with fus- cous, more densely anteriorly, forewings moderately wide, ground color rather densely overlaid with dark fuscous-brown so as almost to con- ceal the former, but leaving a distinct whitish fascia at one-third, the latter is nearly straight, equidistant from the base at both margins, and slightly bisinuate externally, it is heavily shaded externally, especially in dorsal portion, forming a large, triangular dorsal patch not sharply defined externally ; at the end of the cell are two large, dark brown spots ; the dark dusting is somewhat more condensed along the costal margin ; cilia dark gray, sprinkled with whitish and fuscous scales. Hindwings as wide as the forewings, costa not refuse, apex obtuse ; gray, dusted with fuscous, especially along the margins. Abdomen above brown, segments fringed with pale scales; underside of body and legs grayish-white, dusted with brown, apices of tarsal joints paler.
Expanse 15.0 mm., 0.6 inch.
Hab. — Texas, exact locality not known. A female speci- men in my collection, contained in the Hulst Collection, and obtained from Prof. John B. Smith of Rutgers College. It gives me pleasure to name this form after its illustrious collector, the late Rev. George Hulst.
3. B. yuccrecolellan. sp. (Plate I, fig. 3.) — Head dark ochreous; obscurely flecked with some fuscous scales ; antennas rather robust in the male, more slender in the female, fuscous brown, basal joint ochreous. Palpi not slender, alike in both sexes, grayish-ocherous, thickly dusted with dark brown scales, apex of the second and third joint pale. Thorax ochreous-fuscous. Forewings elongate, pointed, ground color grayish-ochreous, overlaid with bark-brown scales, the latter intermixed especially in outer part of wing with pale scales, basal space paler than remainder of wing, limited externally by an irregularly curved line, a large subquadrate costal and a smaller dorsal patch, a heavy dash in the fold, base dusted with fuscous, some scatterd dark scales along the fold, the marginal spots are about equi- distant from the base, remainder of wing more densely overlaid with fuscous scales, especially along the costa, with a nebulous spot about the middle, apical part of wing interspersed with whitish scales, which give when examined with a fairly strong lense a "pepper-and-salt" appearance ; two spots at end of cell, the lower one generally larger

Hab. — Texas.
Five specimens, three females and two males, in the Nat. Mus. Coll. are before me. They bear the label " Bred from Yucca baccata, iss. Apr. 18th, 1897." It is quite likely that freshly bred material may have a decided darker color.
4. B. plmmiierella n. sp. (Plate I, fig. 4.)— Head, palpi, basal joint of antennae and thorax gray, dusted with fuscous, with some metallic lustre; antennae fuscous, very faintly annulate with pale; stouter, finely denticulate and ciliate beneath, cilia \, deeply excised above basal joint in the male, simple and more slender in the female, palpi slender, a trifle longer in the female than the male, second joint dark fuscous externally and along the margins within, third joint nearly as long as the second, thinly dusted with fuscous. Forewings elongate, ground color grayish-white, clouded with dark fuscous ; base dark fuscous becoming paler externally where it leaves an ill-defined, strongly curved fascia, the summit of which reaches to two-fifths and within the latter is the first discal spot, externally the fascia is limited by dark fuscous marginal clouds beginning at one- third, which more or less coalesce and become effaced externally, the fuscous clouding is more pronounced in costal half of wing, two well- marked spots at end cell, another ill-defined, but strongly curved fascia in apical part of wing ; the fuscous dusting is interspersed with whitish scales ; cilia grayish-fuscous, sparsely sprinkled with whitish scales. Hindwings nearly 1, grayish-fuscous, darker externally and along the dorsal margin ; cilia gray, a little over 1, paler towards the base. Abdomen fuscous, anal bush ocherous ; legs grayish-white, more or less thickly— especially externally— dusted with fuscous, tip of tibiae and tarsal joints paler. Expense 10.0-14.0 mm., 0.4-0.56 inch.
Hab. — Plummer's Island, Md.
Six specimens, three males and three females, from the Nat. Mus. Coll. are before me. Taken by Mr. A. Busck at the above locality, July, 1903. Somewhat variable in extent and definition of markings and even in wing form.
WM. G. DIETZ, M.D. i)
Var. fusco-purpurella.
Two specimens taken with the above are decidely dark fuscous brown, sprinkled with whitish scales, the latter more profuse in basal two-fifths, this space is acutely angulated outwardly, the apex of the angle extending beyond the mid- dle of wing length. The wings are somewhat broader than in the typical form, and it may prove to be distinct.
Var. siiuplicella.
A female specimen in my collection from Iowa City, ex- pansion 16.0 mm., 0.64 inch, differs from the above by the second palpal joint being pale at apex, head and basal joint of antennae ochreous-gray, thorax grayish-fuscous. Fore- wings gray, without markings, except a dark fuscous patch at base of costa and two large spots at end of cell. It will probably prove distinct.
5. B. sagitella n. sp. (Plate I, fig. 5.)— Head gray, finely speckled with fuscous, without lustre ; antennae slender, fuscous, very indis- tinctly annulate with pale, finely denticulate beneath, basal joint gray. Palpi moderate (cf) gray, thinly dusted with fuscous, lower margin and a narrow ring before the extreme apex of second joint dark fus- cous, extreme apex pale, third joint conical, two-thirds the length of second. Forewings moderately wide, gray, speckled with dark brown ; a pale fascia at one-third, a little nearer the base on the costal margin and acutely projecting into the median space above the fold, outwardly the fascia is heavily margined with dark fuscous brown, basal portions of wing rather densely covered with dark fuscous scales at the base and along both margins, a fine dark line immediately below the fold ; outer part of wing more densely fuscous in costal portion ; two well marked spots at end of cell ; about six or seven well marked marginal spots around the apex, those on the costa more distinct. Cilia gray, dusted with fuscous scales, especially in basal portion. Hindwings a trifle under 1, grayish-fuscous, rather obtusely pointed, cilia grayish-fus- cous, especially towards the apex, with pale basal line. Thorax and abdomen dark fuscous, anal bush ochreous-gray. Legs grayish-fus- cous, tarsi darker. Expanse 11.0 mm., 0.44 inch.
Hab. — Hazleton, Pa.

6. B. distinctella n. sp. (Plate I, fig. 6.)— Head grayish-white, with some lustre, antennae slender, grayish-fuscous, indistinctly annu- late with paler, basal joint grayish white. Labial palpi long, slender, the third joint three-fourths the length of the second, whitish, rather densely dusted with fuscous scales without, less so within, extreme apex of second joint and basal portion of third whitish. Thorax grayish-fuscous. Forewings elongate, pointed, ground color white, outer three-fifths rather densely dusted with fuscous, especially so ad- joining the whitish basal portion, the latter speckled with fuscous towards the base, thus leaving a nearly white fascia at two-fifths, ap- proximately straight, somewhat irregular without and ill-defined within ; a rather large, ill-defined spot at the middle at one-half the wing length, and two crescent shaped coalescent spots at end of cell, the upper one reaches a trifle further outwardly, their concavity towards the base ; beyond these is a rather large, irregular spot. Cilia gray- ish with some scattered brownish scales. Hindwings 1, gray, dusted with fuscous, especially towards the apex, cilia 1, gray with pale basal line. Abdomen fuscous, segments fringed posteriorly with pale scales. Legs grayish-fuscous, tibia at apex, an ill-defined spot at middle externally, and apices of tarsal joints paler. Expanse 17.0 mm., 0.68 inch.
A female specimen without locality label in the Nat. Mus. Coll., numbered 21,469. It bears some remote resemblance to the European B. phy ridel la, but the insect is lighter in color, more strongly marked, wings, especially the hind wings, wider and less pointed.
7. B. villella Busck. — " Labial palpi light yellowish-brown, black- ish on the outside, Face, head, thorax and anterior wings unicolorous light yellowish brown, the same shade as in pergandella (Triclouella) , without markings of any kind. Posterior wings shining yellowish fus- cous, cilia golden brown. Legs yellowish brown, tarsi on the outside blackish. Alar expanse 15 mm."
The type, a female specimen in the National Mus. Coll., was bred by Mr. Pergande from Xalisma {Andromeda) ligus- trina, collected at Cabin John, Md. Mr. Busck referred this species to his genus Triclonella. In a personal conversation, however, he informs me that it belongs to Blastobasis. The venation of the hindwings is that of the genus under con- sideration, but as to the forewings I could not satisfy myself. It certainly is an aberrant form.
WM. G. DIETZ, M.D. 11
ZEXODOCHIUM Wish..
Type. — Monopetali Wish.
Agrees with Blastobasis in venation, and from which it dif- fers by the conchyloidal shield of close set scales, replacing the pecten of the basal joint of the antennae. Lord Walsing- ham describes the palpi "middle joint densely clothed." While this cannot be said of the two species which I refer here, I consider the character too vague to be of generic value.
1. Z. citricolella Ch. (Plate I, figs. 7, la.)— Head white, thinly speckled with pale fawn-colored scales ; face smooth, vertex somewhat rough-scaled, Antennae white, tinged with gray, finely denticulate beneath, basal joint with a few scattered fawn-colored scales; pecten replaced by a flattened, curved tuft of white scales. Labial palpi long, not very slender, white, thickly sprinkled, especially externallv, with brownish scales, third joint nearly as broad at base than the apex of the second joint and about two-thirds the length of the latter {<?). Forewings moderately wide ; white, suffused with dark fuscous and densely sprinkled with brown and fawn-colored scales ; markings dark fuscous, in longitudinal lines or patches, somewhat as follows : A subcostal streak for about two-fifths from the base, a line above the fold of equal extent, a heavy, irregular streak in the fold from near the base to about the middle where it almost joins a dark ir- regular spot in the fold ; a short line near the base and within the dorsal margin ; above the plical spot and about the middle of the wing is another less distinct spot, and above this a dark line parallel to the costa and ending above the two well marked spots at end of cell, two short dashes in dorsal half of wing, the outer one ending immediately below the lower spot at end of cell, several short dashes in apical part of wing, between these latter are a number of short, white, longitudinal lines. Cilia whitish, sprinkled with pale brown scales, forming irregular lines. Hindwings a trifle under one, pale yellowish-gray, shining, thinly sprinkled with fuscous externally ; cilia scarcely over 1, yellowish-gray, paler at base. Thorax whitish, thickly overlaid with brown, patagia more thinly sprinkled. Abdomen silvery gray above, anal bush concolorous, underside white. Legs white, slightly dusted with brown ; hind tibia very coarsely rough haired. Expanse 12.0-19.0 mm., 0.48-0.76 inch.

granate apple, April 21, 1879." Another specimen in my collection, also a male, from Brownsville, Texas, is much smaller and less distinctly marked.
Lord Walsingham's statement concerning the palpi "ter- minal joint more than two-thirds the length of the median," refers to the female.
What Chambers meant by his statement, " the fact that the submedian vein of the forewing gives off a branch to the dorsal margin from about the middle which I have not ob- served in any other Tineid " is difficult to explain, as neither Mr. Busck nor myself have been able to discover such a vein. Z. coccivorella Ch.
I give here Mr. Chambers' short description: "As men- tioned in the description of citricolella, this species, of which I have seen two damaged females, has a tuft projecting from the basal joint of the antennae. Face elongate and narrow, more convex than in citricolella. It is smaller and not so slender. Submedian vein of forewing not branched. It is sordid whitish with silken lustre, dusted with fuscous, a fus- cous streak on forewing at base of fold, one near the base within the costal margin, apical part of wing densely dusted with fuscous. Hindwings stramineous."
" Comstock informs me that the larva lives on a large coccus on oak."
Lord Walsingham* makes the following note on this species : Type. — A female. Habitat. — Cedar Keys, Florida. Larva in coccid-scales on oak {Kermes, species, near pall idus Reaumur). Collected in March; issued between April 1-10. This species is omitted from Dyar's list. If the type is still extant, there should be no difficulty in placing it in its proper genus. Chambers' reference to the neuration is doubtless incorrect."
I have no comments to make. The type is not in the Nat. Mus. Coll. Notwithstanding the difference in their larval habits I have a suspicion that coccivorella is only a varietal form of, if not identical with, citricolella. As I have not seen the former, this is merely conjectural.

VALENTINIA Wish. Type glandulella Riley.
Labial palpi long, recurved, slender ; generally more robust with the terminal joint relatively shorter in the male than in the female. Antennae shorter than the forewings, basal joint broad, convex, with distinct pecten, deeply excised above the latter with a scale tuft in the excision in the male ; shaft stouter in the male than female. Forewings elongate, pointed, costa approximately straight, depressed to apex in apical part. Twelve veins, 7 and 8 stemmed, 7 to costa, remaining veins free. Hindwings variable ; nearly as wide as the forewings, with dorsal margin more or less distinctly curved, cilia scarcely over \\, or scarcely half as wide as the forewing, dorsal margin nearly straight from near the base to the acutely pointed apex and cilia 2 or over. Eight veins, 6 and 7 separate, 4 and 5 stemmed, 3 free, arising before the angle of the cell. Abdomen somewhat flattened. Hind tibise long haired above.
As far as known the genus is only represented in North America.

slender, simple, and finely denticulate below. Labial palpi long, curved upward, decidedly stouter in the male than the female, grayish- white, the second joint externally, densely overlaid with dark fuscous scales, except extreme apex, third joint less densely speckled. Fore- wings moderately wide, margins nearly parallel from near the base to apical fourth, equally narrowed thence to apex, latter rather obtuse ; ground color whitish, more or less densely overlaid with dark brown scales, forming a fairly constant pattern, a whitish fascia at one-third, curved outwardly and somewhat angulated in the fold, this fascia is shaded with dark fuscous within, which increases in density towards the base, outwardly the fascia is densely shaded with dark fuscous, which extends a little further along the costa than along the dorsal margin ; two well marked spots at end of cell and immediately beyond these a transverse costal and dorsal spot, which form somewhat of a fascia, interrupted in the middle third, beyond these spots are six or seven, more or less well marked marginal dots ; remaining surface more or less densely speckled with fuscous ; cilia gray towards the base and speckled with white and fuscous scales ; outer portion traversed by several ill-defined longitudinal lines.

Larva in acorns. I have examined Zeller's type of nubi- lella. A female, bearing his green label — Blast obasis nubi- le! la Z. ; red type label 1714, locality label Dallas, Tex. Boll., compared with specimen oiglandulella Riley, in my collection, found identical with the latter. Lord Walsingham 's* refer- ence to Mr. Chambers' and Mr. Riley's assertions concern- ing the identity of nubilella ZeW., triangularisella Ch., and sciaphilella Zell., must be corrected as follows : nubilella Z., as there and above stated, is synonmyous with gla?idulella R.; triangularisella Ch., and sciaphilella Z., are the same and belong to Holcocera — sensu Clementi. The type of sciaphi- lella presents an anomaly in the neuration of the hindwings, as it has 8 veins on the left side {Holcocera) and 7 (Blastoba- sis) on the right, veins 3 + 4 are stemmed. This no doubt accounts for Mr. Busck referring this species to Blastobasis.

2. V. fractilinea Zell.
Zeller describes this species as follows :
" Parva, alis ant. brevius culis ; canis, striga ante mediam albida, in angulum fracta, pastice nigricani-marginata, punctu disci postum strigulaque venae transversa inferias incrassata nigris cJ1.
" Palpi similar to those of r.etectella Zell., though a trifle shorter, dark fuscous externally, apex of second joint pale yellowish, third joint less acutely pointed and a trifle darker at the apex. Abdomen broad — as in retectella — -pale yellowish gray, underside paler.
" Forewings 2|'" long, broad and obtuse as by B. sciaphilella, gray- ish-white, moderately dusted with blackish scales, more densely so on the basis, outer half of costal and dorsal margins. The transverse line before the middle forms a very conspicuous angle, more or less distinctly lined within with dark fuscous, an indistinct spot before the angle ; externally distinctly lined with dark fuscous, which is widest towards the costa. Behind the apex of the angle, though a trifle higher, lies in the paler median space, a dark spot. Two coalescent brownish spots form a transverse bar, which almost attains the hind margin.
" Hindwings scarcely half the width of forewings, equally narrowed, rather sharply pointed with nearly straight posterior margin ; grayish fuscous, cilia pale with a very fine, pale yellowish basal line." Two 9 9.
Not known to me. Type and paratype in the Walsing- ham collection.
3. V. qiiaiutaiicella n. sp. (Plate I, fig. 9.)— Head, basal joint of antennas and thorax pale mouse gray, minutely speckled with fus- cous ; shaft of antennas grayish-fuscous, very indistinctly annulate with pale ; in the male stouter, excision above the basal joint not profound and projecting scale tuft small, finely denticulate and ciliate below ; in the female more slender, simple. Palpi moderate, stouter in the male than female, grayish- white, densely dusted without, less so within, with dark fuscous, tip of second joint pale, the latter about one- third longer than the terminal joint. Forewings moderately wide, widest near the base, from thence very gradually narrowed towards the apex ; ground color dirty white, overlaid with fuscous scales in varying density, basal third paler, limited externally by an ill-defined outwardly convex whitish fascia, which is subangulated about its mid- dle, a dark dash in basal space beneath the fold, and a faint spot just before angle of fascia ; outwardly the fascia is limited by an ill-defined costal and dorsal spot, remainder of the wing, especially along the margins more densely sprinkled with fuscous scales ; a little beyond the angle of the fascia is a well marked, somewhat elongated, dark fus-

cous spot, two less distinct, roundish dots at end of cell, and beneath these on the dorsal margin a small patch ; cilia gray, thinly dusted in their basal portion with whitish scales, interspersed with pale fus- cous, two or three ill-defined longitudinal lines towards the apex. Hind- wings narrow, lanceolate, scarcely over \, gray, infuscate towards the apex ; cilia 2, gray, with two or three longitudinal lines near the apex. Abdomen fuscous ; anal bush ochreous, ventral surface pale ochreous, more or less suffused with fuscous, except last two seg- ments. Legs whitish, more or less densely suffused and speckled with fuscous, tibiae at base, an oblique band of posterior tibiae above the middle externally and end of tarsal joints, pale. Expansion 12.0-14.5 mm., 0.48-0.58 inch.
Hab. — No exact locality given.
Six specimens from the Nat. Mus. Coll., without locality labels, were bred by Mr. Quaintance from apple, and it gives me pleasure to name this species in his honor. The speci- mens, which were not spread, vary more or less in distinc- ness of markings as well as density of the fuscous dusting. This species comes nearer to glandulella, from which it is at once distinguished by the much narrower hindwings and longer cilia of the same, its markings, though similar, are far less pronounced ; in form of hindwings, it would appear to be close to retectella, with which it agrees in size.
4. V. nothrotes Wish.
Lord Walsingham's description of this species is as fol- lows :
"Antennae pale slaty-brownish. Palpi grayish-brown, with whitish sprinking. Head and thorax whitish, with grayish-fuscous speckling, especially in a band across the front of the thorax and another across the posterior end of the tegulse. Forewings dirty white, profusely sprinkled with grayish-fuscous, of which a transverse fascia crosses the wing at one-third ; this is slightly angulated outward in the middle, and partially diffused outward in the middle and about the costa ; at the end of the cell a somewhat less defined, straight, transverse fascia occurs, absorbing the two spots which would otherwise appear at the end of the cell, corresponding to a small discal spot at about the mid- dle of the wing ; the apical area is thickly bestrewn and mottled with grayish-fuscous ; cilia brownish-gray, sprinkled with whitish- and gray- ish-fuscous atoms. Hindwings brownish-gray ; cilia slightly paler. Abdomen slaty-gray, anal tuft paler. Legs pale, brownish-gray. Alar expanse 12.0 mm."

Lord Walsingham states further :
" A small and narrow winged species, somewhat similar in markings to retectella Zell., with which it agrees in having a strong notch and pecten on the antennae, and 4 and 5 of the hindwings stalked, but is quite distinct in size and shape."
5. V. retectella Zell.
Of this species the author gives only a comparative de- scription relative to his umbilella — glandulella Riley — as follows :
"A smaller American specimen, female, forewings 3vn long, cannot be identified with either mibilella Zell., or sequel I a Zell., as the hindwings are still narrower and more pointed than in the former species. The forewings of this species — retectella — are not so dark as in mibilella. The transverse white line is simply convex outwardly and some- what wavy, wider, and limited towards the base by an ill- defined spot of blackish scales ; the strongly marked spot in the median space is present. The two spots at end of cell are represented by a heavy transverse spot. Hindmargin infuscate, without black spots. Ovipositor long, awl-shaped, depressed."
Hab. — Texas.
Unknown to me in nature. The type, a female, is in the Walsingham collection.
6. V. floridella n. sp. (Plate I, fig. 10.)— Palpi pale ochreous, dusted with fuscous externally, apex of second joint pale, lower edge of second joint somewhat roughened with dark brown scales ; a little stouter in the male, terminal joint two-thirds the length of the preced- ing ; female : slender, terminal joint three-fourths the length of the second. Head, basal joint of antennas and thorax pale ochreous, the latter and vertex dusted with fuscous. Antennas ochreous-fuscous, deeply excised above basal joint in the male with conical tuft in the exci- sion. Forewings rather narrow, of nearly equal width for two-thirds, thence gradually narrowed to the apex, costal margin approximately straight for two-thirds, apical third depressed to the apex ; ground color sordid ochreous, suffused with fuscous brown without any par- ticular pattern, the dark colors more evident along the margins, also some longitudinal streaks, especially along the fold and below the costal

Four specimens, one male and three females, in Nat. Mus. Coll., bear the label, " From 9 cone of Zamia integri folia.'''' Not clearly related to any of the species known to me. No indications of a fascia at one-third of forewing. The diver- gent lines in middle space of forewing are distinct in only one, indistinct in another, and obsolete in the remaining two.
7. V. confectella Zell. (Plate I, fig. 11.)
In "Anmerkung 1," in his description of Hypatima sub- senella, Zeller very doubtfully refers a somewhat worn speci- men from Texas to this species. The greatest difference he finds is the very narrow hindwings, without, however, recognizing the differences in venation. I herewith give his comparative description :
"The pale gray ground color of the forewings have a somewhat yellowish tint. A dark shade at the base of costa. Instead of the first costal spot, is a very fine line visible. The short plical line above the dorsal patch is wanting, and the latter extends further towards the base, while a longer line within the fold, and nearer the base is quite distinct and of which no trace is visible in subsenella. The streak before the end of the cell is wanting entirely and a costal spot imme- diately above those at end of cell is quite evident."
I have examined the type of this species, a female, in the Cambridge Museum, and offer the following complimentary notes in order to enable the recognition of this form in the future :
WM. G. DIETZ, M.D. 19
"Palpi, head, basal part of antennas and thorax, sordid ochreous- white with some lustre. Palpi slender, the third joint two-thirds the length of the second, the latter dusted with fuscous externally. Thorax dusted with fuscous on the disk. Forewings sordid white, with a very faint yellowish tint, dusted with fuscous. Basal space not well defined externally, with a longitudinal line above the fold ; a dorsal nebulous patch near the base ; very faintly indicated patches on both margins at one-third, a longitudinal first discal spot and two spots at end of cell with faint costal patch above ; apical part of wing more densely dusted. Hindwings scarcely l, costa retuse in outer half, grayish- white dusted with fuscous ; cilia 2. Abdomen pale ochreous-fuscous. Underside pale ochreous-white. Legs ochreous-white ; tibiae and tarsal joints pale at the apex, fuscous externally." Expanse 12.0 mm., 0.48 inch.
Hab. — Texas (Dallas, Boll collector).
Veins 4 + 5 of hindwings stemmed, 3 before angle of cell. A male specimen in my collection, from Montclair, N. J., and received some years ago from Mr. W. D. Kearfott, agrees in every respect with this species, except that the dark line above the fold in basal space is replaced by an elongate nebulous patch. There is a faint nebulous costal patch beyond the middle and a small spot below the costa and just before the upper spot at end of cell.
8. V. repartella n. sp. — Entire insect pale creamy yellowish Head, thorax, and basal joint of antennas very slightly touched with pale fuscous ; antennae (male) slender, slightly thickened towards the base, excision above basal joint not profound, projecting scale tuft long, shaft shortly ciliate, but not denticulate within, a trifle darker than the basal joint above, pale brownish beneath. Palpi (male) slender, long, terminal joint two-thirds the length of the second, dusted with fuscous, more densely without, leaving the base and apex pale. Forewings rather narrow, of approximate equal widths of basal half, thence gradually narrowed to apex, latter pointed ; extreme costa in basal portion brownish fuscous, surface very slightly suffused with pale fuscous towards the base and reddish-brown towards the apex ; a small, elongate spot in median space before the middle, a little nearer the costa than the dorsal margin, two scarcely perceptible dots at end of cell, along the base of costal cilia are four or five somewhat elon- gate spots, and a similar one just below the apex on the dorsal margin ; cilia concolorous with a few scattered pale brown scales.

Two cf d\ in the Nat. Mus. Coll., collected by E. Oslar. One of these is minus its left fore- and hindwing, which are contained in a slide ; the other is minus its left forewing. The pale, yellowish color distinguishes this species at once from all others at present known to the writer. I retain the MSS. name given it by Mr. Busck.
EURESIA gen. n. Type pnlebella.
Labial palpi long, diverging, pending (in the dead insect), second joint rather thick, roughened beneath with scales, third joint shorter than the second, slender, and like the latter roughened beneath with scales. Antennae (&) shorter than the forewing ; basal joint short and broad, pecten setaceous, shaft deeply excised above the base, neither denticulate or ciliate beneath. Forewings moderately elongate, pointed, twelve veins, vein 7 + 8 stemmed, 7 to costa, remaining veins free, but crowded at end of cell, posterior angle of latter very close to dorsal margin. Hindwings much nar- rower than the forewings, lanceolate, pointed, costa slightly refuse in outer half, cilia long ; eight veins, vein 4 before angle of cell, 5 + 6 free. Posterior tibia rough haired above.
Represented by a very small species strongly resembling and readily to be taken for a Pigritia. Distinguished from the latter by its long palpi and hindwings with eight veins. From the other genera of Blastobases with eight veins in the hindwing, by veins 2, 3 + 4 of the latter arising from the posterior median vein.

CALOSIMA gen. n. Type argyrospiendella.
This genus differs from Holcocera in the presence of a con- chiloidal shield of close set scales, on the basal joint of the antennae instead of a pecten and the absence of discal spots or other markings of the forewings.
The head is rather small and depressed, the face strongly receding, giving thus the thorax a somewhat more convex appearance as is usual in this group. The palpi are long, slender and recurved, the second joint scarcely thickened towards the apex. The antennas are not excised above the basal joint in the male. Forewings more of less elongate, acutely pointed ; 12 veins, 7 + 8 stemmed, 7 to costa. Hind- wings 8 veins, 3 + 4 connate or short stemmed, 5 connate with the stem.
In appearance the two species here described have rather an CEcophorid habitus than that of a Blastobasid. The vena- tion, however, admits of no doubt. This genus holds the same relationship to Holcocera as Zenodochium holds to Blasto- basis.
The two species, though closely allied, may readily be distinguished as follows :
Larger, extreme costa pale, hindwings obtusely pointed clianella.
Smaller, extreme costa dark brown, hindwings acutely pointed.

Differs from dianella by its narrower wings, acutely pointed hindwings, costa of forewings nearly straight, gener- ally paler color and smaller size. Three specimens in my collection, from as many localities, would seem to indicate a rather wide distribution of this interesting addition to our fauna.
2. C. dianella n. sp. — Palpi slender, reaching to antennal inser- tion, sordid white, dusted externally with fuscous, the third joint three- fourths the length of the second. Head and thorax creamy white, the former very smooth scaled with a greenish lustre, the latter lightly dusted with pale ochreous-fuscous with some lustre. Antennas slender, simple ; slightly pubescent beneath and not excised above the base in the male ; basal joint of moderate length, slightly curved, nearly twice as long as wide, creamy white, conchoidal shield of long, close set scales, concolorous with basal joint. Forewings relatively wide, costa slightly convex from the base, sharply pointed, creamy yellow, thinly overlaid with pale ochreous-fuscous except for three-fourths of the costal margin, which is thus left paler; no markings; cilia pale ochreous-yellow.

In coloration this species does not differ from the preced- ing, except perhaps in the more pronounced yellow, it is, however, larger, wings relatively wider, the hindwings obtuse at apex, and vein 10 of forewing is somewhat removed from angle of cell ; 3 + 4 of hindwing from a very short stem, 5 subconnate with the latter.
HOLCOCEKA Clem. Type chalcofrontella.
Catacrypsis Wish., Cy notes Wish., Prorodica Wish., Hypatopa Wish. {Hypatima H. S.).
Tongue long, scaly at base. Labial palpi long, ascending, generally recurved. Antennas about three-fifths the length of the forewings, basal joint broad with setaceous pecten ; shaft either excised above the basal joint in the male, or else similar in the sexes, frequently ciliated in the male. Fore- wings more or less elongated, pointed, without scale tufts ; 12 veins, 7 + 8 stemmed, 7 to costa before the apex ; rest of veins free. Hindwings ovate to lanceolate ovate, generally acutely pointed ; costa more or less refuse beyond insertion of vein 8. All veins present, 3 + 4 generally stemmed, rarely connate, 5 free, connate with stem of 3 + 4 or arising from stem of the latter. Brush of bristly hairs of hind tibia always well developed.
The genus as here defined comprises a rather large num- ber of species of diverse appearance and habitus. They are generally attracted by light. Of their primary stages, food plants, etc., but little is known.
Clemens in his description of the genus says : " A furcate apical branch near its end (the anterior median), the lower branch running into the apex of the wing." This is not the

case, as this branch (vein 7) goes to the costa, though close before the apex. Veins 3, 4 and 5 of hindwings vary greatly in their origin, not only in different species, but in different individuals of the same species and even in the same indi- vidual.
In the following table I have endeavored to proceed from the broad winged and dark colored forms to those with nar- row wings and of light color, but from the nature of things this could not always be carried out. Holcocera arizonella Krft. belongs to Colinita Busck. {Scythris Hbn.).

Seven specimens, two cf cf and five 9 9 , are before me. Closely related to H. aphidiella, from which it is distinguished by its uniform dark brown color of forewings and absence of discal spots.
Var. basipallidella differs from the typical form by the basal two-fifths of the forewing being somewhat paler than the rest of the wing, this paler space is irregularly angulated externally, and the first discal spot is situated on its edge ; the two spots at end of cell are generally distinct, and the immediate space surrounding them a trifle paler. Expansion 16.0-18.0 mm., 0.64-0.72 inch.
Hab. — Penna. (Hazleton), Mass. (Cohasset), New Hamp. (Hampton).
Both the typical form and the variety lack entirely the white tipped scales of aphidiella.
2. H. aphidiella Wish. — " Antennas strongly notched beyond the basal joint, the basal extremity of the notch very plainly indicated by a truncate patch of scales from the lower margin of which the slender bent stem continues ; beyond this they are biciliate three-fourths ; basal joint with a strong scale-pecten ; tawny-gray. Palpi slender, pointed, slightly recurved reaching, beyond the basal joint of the antennae, the terminal joint nearly as long as the median ; brownish cinereous, the median joint darkened externally. Head and thorax with an iridescent greenish lustre ; tegula? tipped with cupreous. Fore- wings with 12 veins, 7 and 8 stalked, 7 to costa ; tawny reddish-gray ; a darker discal spot, a little beyond one-third, is succeeded by a larger spot (or confluent pair of spots) at the end of the cell ; below which the outer extremity of the fold is also dark shaded ; cilia brownish cinereous ; underside not iridescent. Hindwings with 8 wings, 5 out of the stalk of 3 -J- 4 ; rather shining, brownish-gray with greenish and cupreous iridescens towards the base ; cilia brownish cinereous, with a slight ochreous tinge ; underside decidedly iridescent. Abdo- men brownish cinereous. Legs brownish cinereous. Alar expanse 13.0 mm."

The similarity to quisquiliella Zell., as remarked by the author, is .consider- able, but the latter lacks the greenish-cupreous reflections, and the white tipped scales of forewing ; it is a larger insect, the male antennas less deeply excised, cilia under i, the mod- ding more pronounced ; altogether it is a lighter colored insect.
3. H. estriatella n. sp. (Plate II, fig. 15.) — Head rather narrow, ochreous, tinged, especially on the face with fuscous. Antennae (cT) rather robust, basal joint ochreous, fuscous on the disk, pecten long, fuscous, shaft fuscous, paler toward the tip, indistinctly annulate with ochreous, finely denticulate and ciliate beneath, deeply excised above the base ; cilia 1. Palpi long, slender, reaching considerably above level of head, second joint dark fuscous without, paler within, extreme apex, like the third joint, whitish, latter very slender, as long as the second, very sparsely speckled with pale brownish scales. Thorax shining, ochreous, disk suffused with fuscous, patagia paler, purplish-brown anteriorly. Forewings moderately wide, not widened exteriorly, costal margin very slightly depressed about the middle ; ground color white, overlaid in varying density with dark purplish-brown, as follows : Base dark, shading off outwardly at one-third, the ground color forms an out- wardly sharply angulated fascia, not defined within, sharply so with- out, summit of angle on the fold, the fascia recedes a trifle outwardly on the costa, externally the fascia is heavily shaded with very dark fus- cous-brown, more so on the costal portion, where it extends to the outer third, but is somewhat interrupted about the middle ; the re- mainder of the middle space is less densely speckled with dark fuscous, except along the fold, first discal stigma absent, two large, coalescent spots at end of cell, below which and a trifle outwardly is an ill-defined spot on the dorsal margin, an oblique costal blotch beyond the second discals, not reaching middle of wing, remainder of apical part of wing speckled with fuscous, the latter forming an ill-defined curved line before the apex, a dark line along base of cilia around the apex, most marked at extreme apex ; cilia gray, basal part speckled with white, intermixed with fuscous scales. Hindwings nearly 1, gray, with sheen, dusted with fuscous ; cilia under 1, gray, paler outwardly. Underside of forewings dark, hindwings pale fuscous. Abdomen fus- cous, anal bush pale.

Five specimens, two males and three females, in my collec- tion, four of these are from the last-named locality, and have the ground color of the forewings more suffused with fus- cous. Chambers supposed this species to feed upon yucca. Not easily confounded with any other species of this genus. The dark fuscous lines of the forewing, corresponding with the neuration, give it a very distinct appearance, which is approached only by the following species {nigristriata) , the latter, however, is much smaller and lacks the dark lines in the apical part of the wing.
5. H. nigristriata Wish.
The author describes this specimen as follows : " Antennae yellowish ; basal joint considerably widened, with strong pecten, dirty whitish. Palpi white, sprinkled with blackish scales, very densely on the outer side. Head and thorax white, sprinkled with blackish scales. Forewings white, much sprinkled and striated with blackish scales ; an elongate patch of these scales extends from the base along the fold to about one-sixth, and is diffused downward

Type in the author's, paratype in Nat. Mus. Coll. The latter I have examined. The dark streak in the fold extends the entire length of the latter. Its relationship to gigantella has been referred to under that species. Although the male is not known, I entertain scarcely a doubt that the species belongs into the section — "Antennae of male excised above the base " — Holcocera sensu Clemensi. In the synoptic table I place it tentatively next to gigantella, its nearest ally.
6. H. purpuro Cornelia Clem.— " Forewings uniform dark pur- plish-fuscous, with an indistinct, blackish median dot, and two of the same hue in the middle of the wing above the fold. Hindwings dark yellowish-fuscous, cilia same. Head and thorax fuscous with a red- dish hue. Face tinted with yellowish. Labial palpi fuscous. "
The above is Dr. Clemens' short description. The type, a female, in fairly good condition, is in the Clemens' collec- tion at the Academy of Natural Sciences, Philadelphia. A number of specimens in my own collection. The labial palpi are long, recurved, a trifle more slender and longer in the female than the male, the third joint two-thirds the length of the second, sordid ochreous, densely dusted with dark fuscous, less so towards the apex, the lower edge somewhat roughened with dark fuscous scales. The head and basal joint of antennae are sordid ochreous, more or less densely speckled and suffused with reddish fuscous. Antennal shaft fuscous, slender; in the male moderately excised above the base, with obliquely truncated scale tuft, ciliated; cilia scarcely \. The purplish fuscous coloring of

the forewings is uniform, though more pronounced in costal portion of the wing; a slightly paler shade, especially before the first discal and surrounding the spots at end of cell is noticeable in some specimens. The first discal spot before the middle, and the two spots at the end of cell, are quite distinct in the type and all specimens before me. Hind- wings nearly 1, with considerable lustre, cilia under 1, paler than the wing. Abdomen fuscous, paler beneath ; anal bush ochreous. Legs fuscous, especially anterior and median ; hind tibia dark gray with median band externally and at apex, paler ; rough haired above ; tarsal joints paler at apex. Ex- pansion 17.0-18.5, 0.68-0.94 inch.
Hab. — Penna., Maryland (Plummer's Island). Occurs un- doubtedly over whole Atlantic district.
Might be confounded with H. dives, but differs, by its smaller size, relatively broader forewings, well marked dis- cal spots, paler coloring and less lustre, and above all by the less profound excision and much shorter cilia of the male antennae. Agrees in wing form and antennal structure with chalcofrontella, and resembles somewhat var. fumerella of that species, but lacks the mottling of the latter.
7. H. ochrocepliala n. sp.— Head, thorax, and palpi pale ochre- yellow ; the latter long, ascending but slightly recurved, terminal joint almost as long as the second, speckled, especially externally, with fuscous scales, leaving the apices of second and terminal joints paler. Basal joint and two or three basal joints of shaft of the antennae yel- lowish-white, very slightly speckled with fuscous, remainder of shaft grayish-fuscous, anterior (exclusive of patagia) and posterior margin of thorax dark purplish- brown. Forewings moderately wide, grayish- fuscous, suffused in patches with dark fuscous, and overlaid with pur- ple, extreme base, excepting its costal margin, pale ochre-yellow ; first discal spot distinct, before the middle and nearer to the costal margin, two spots at end of cell less distinct, coalescent, cilia grayish-fuscous, paler at base. Hindwings 1, grayish-fuscous ; cilia scarcely over \, grayish-fuscous, paler at base ; vein 5 out of stalk 3+4. Abdomen above fuscous, beneath sordid yellowish-white, anal segment deep ochreous. Underside of thorax and legs pale ochre-yellow, speckled more or less densely with fuscous, leaving the ends of tibia? and poste- rior tarsal joints paler. Expansion 16.0 mm., 0.64 inch.

Hab.—W. Va. (Aurora), Md. (Frederic).
A female specimen in the Nat. Mus. Coll., collected by Mr. O. Heideman, and a male in my own, are before me. Unlike any other species. The pale yellow color of the head, thorax and base of forewing gives this insect a characteristic appear- ance. The somewhat moddled appearance of the remainder of the forewing resembles chalcofrontella, var. fumerella, but is paler.
8. H. crassicornella n. sp. (Plate II, fig. 16.)— Palpi rather robust, terminal joint three-fourths the length of the preceding, gray, rather densely sprinkled externally with dark fuscous, lower margin and apex of second joint paler. Antennas robust, rather deeply ex- cised (male) above the base, with a large conical scale tuft, ochreous above shading to fuscous beneath, ciliate, cilia \. Head gray, suf- fused with dark fuscous. Thorax grayish-fuscous anteriorly with a blackish-brown transverse line behind the anterior margin, which extends upon the patagia ; posterior two-thirds a sordid ochreous, dusted with gray. Forewings rather wide, ground color ashy-gray, overlaid in varying density with dark .fuscous, broad scales, inter- spersed with narrow, hair-like pale scales ; the dark scales are aggre- gated into irregular patches here and there, especially along the costal margin ; before the middle and close to the dorsal margin are two short lines, converging into a point towards the base, between these the ground color is rather pale, immediately behind the base of this triangle the wing is speckled with dark scales, first discal spot at two- fifths, large and distinct ; at the end of the cell are two very distinct, somewhat remote spots connected by a fine black line, the lower one of these spots is triangular with apex directed towards the base, in the apical portion of the wing is a strongly angulated line, a series of four large spots along the base of costal cilia, some less defined ones along base of dorsal cilia. Cilia gray, with about three pale, not very dis- tinct, longitudinal lines in outer half, the outermost of these lines occupies the outer margin of the cilia. Hindwings about 1 (?); fus- cous ; cilia under 1, gray, with pale basal line. Abdomen pale gray- ish-fuscous beneath, anal bush the same. Legs dark gray, anterior and middle spotted with blackish, posterior tibia at base and oblique band at middle exteriorly, whitish; tarsal joints slightly paler at apex. Expansion 15.0 mm., 0.6 inch.
Hab. — Florida.
A unique male specimen, simply labeled " Florida," in the Nat. Mus. Coll. Very distinct and unlike any other. The antennae — male at least — are very robust, the wing markings quite peculiar.

9. H. moclestella Clem. — " Forewings fuscous, the basal por- tion of the wing paler and shining, and has a faint grayish hue ; in the middle of the wing is a dark fuscous spot. Antennae, head and labial palpi fuscous." The above very short description by Dr. Clemens needs amplification. Labial palpi long and slender; head and thorax grayish, speckled with fuscous. Forewings relatively wide, the basal third limited externally by an angulated line, the dorsal extremity of which is nearer the base than the costal end, the summit of the angle nearer to the costa ; this space is grayish white, shining, dusted with, and especially along the margins, dark fuscous-brown, an ill-defined black spot before the summit of the angulated line, remainder of wing dark gray, densely overlaid with dark fuscous, especially in costal half of wing ; a dark spot before the middle of wing just beyond summit of angulated line, two ill-defined spots at end of cell ; the apical part of the wing is slightly sprinkled with whitish scales ; cilia gray, sprinkled with fuscous. Hindwings not quite 1, pale fuscous, cilia paler. Abdomen fuscous. Legs grayish fuscous; hind tibia with an oblique, whitish, median band, tarsal joints paler at apex. Expansion 15.0-16.0 mm., 0.6-0.64 inch.
Hab. — Atlantic States.
The type in fairly good condition in the collection of the Amer. Entom. Society, Philadelphia, is a female, which I have carefully compared with a specimen in my collection, also a female. I have seen no male, and the presumption that the male antennae are excised above the basal joint rests entirely on the fact that Clemens placed it in his genus Holco- cera — antennae excised above the basal joint. Mr. Busck's statement* that this species is identical with Blastobasis nubilella Zell., and Holocera glandulella Riley, is erroneous. The last two named refer to one species and belong to the genus Valentinia Wish.

(Plate II, figs. 17, Yla-d.) — Head, basal joint of antennas and palpi, sordid yellowish, latter long, recurved, third joint scarcely shorter than the second, the latter externally except at tip, the terminal one entirely, thickly dusted with dark fuscous. Stalk of antennas fuscous, except at its base ; excised above basal joint with conical scale tuft and shortly ciliate in the male.

densed into spots and blotches, an elongated patch at basal part of costa, an irregular spot at one-third, a larger one at three-fifths and another smaller one at about three-fourths of costa, from the latter begins a strongly curved or subangulated line in apical part of wing which ends in a spot on the dorsal margin beneath the end of cell ; from the second costal spot starts an irregular angulated line or fascia, which ends in a dorsal spot just before the middle, this line reaches to the very distinct first discal spot above the fold, and also another less distinct spot beneath the fold. Two well marked spots at end of cell ; a row of dark spots along periapical margin which send short streaks into the basal half of the cilia ; there is some condensa- tion of the dusting along the fold, and a more or less distinct blotch on the dorsal margin near the base. Cilia yellowish-gray, with a pale line before the middle and another less distinct before the free margin. Hindwings nearly 1, obtusely pointed, yellowish-gray, dusted with fus- cous and having considerable lustre ; cilia pale grayish-yellow, with pale basal line. Abdomen grayish-fuscous above, grayish-ochreous beneath, especially towards the end, anal bush grayish-ochreous. Legs pale grayish-yellow, dusted and spotted with fuscous, ends of tibiae, an oblique band on posterior tibiae externally and ends of tarsal joints paler. Expansion 14.0-16.0 mm.,. 0.52-0.64 inch.
Hab. — Atlantic and probably Middle States.
The two specimens representing the types in the Clemens' collection at the Academy of Nat. History, Philadelphia, and labeled as such by Mr. Busck are not identical, the specimen bearing label 201 is the type and corresponds with the de- scription. The other specimen marked 202 and marked light variety, corresponds rather with modestella Clem.
I have bred this species in considerable number from the fruit racems of sumach — Rhus typhosa — collected end of July. The imagines appearing from middle to end of the following June. It is my opinion that the larva? is predaceous on other larva?.
There are several variations from the typical form which require special mention.
Var. minorella. (Plate II, fig. Vie.)
A somewhat smaller form, of which six specimens are before me, four in the Nat. Mus. Coll. and two in the collec- tion of Mr. W. D. Kearfott. They all bear the label " Lewis- burg, Pa.," bred from chestnut burrs. Four of the speci- mens have the dark dusting of the forewings much more dif-

fused, whereby the distinct spots and blotches of the typical form become more or less obliterated. Discal spot and two at end of cell distinct, a small spot of the pale yellow ground color immediately before the lower spot at end of cell. Two of the specimens — Mr. Kearfott's — have the dusting less dif- fused, in fact are lighter than typical specimens. The wings in this variety appears to be relatively narrower than in the former. It may prove a distinct species. Expansion 13.0- 15.0 mm., 0.52-0.6 inch.
Var. fumerella.
Differs from the typical form by its general dark colora- tion. Head, basal joint of antennae, palpi and thorax sordid, grayish-ochreous, dusted and speckled more or less densely with fuscous. Forewings grayish-fuscous ; markings as in the typical form. The ground color in some specimens has a slight ochreous tinge. Expanse 17.0-18.5 mm., 0.68-0.74 inch.
Have bred this form likewise from the fruit racems of sumach. It is distinctly larger in size than the typical form, wings relatively broader. Rubbed or flown specimens might be confounded with H. purpurocomella, but in the latter species, aside from the absence of markings of forewings, the head, thorax, antennas and palpi are grayish-fuscous.
Var. quisquiliella Zell.
Differs from the typical form by its more elongate and pointed forewings, its relatively narrower hindwings ; dust- ing of forewings the same, but more suffused ; appearance of insect more gray with a pale yellowish tinge — possibly due to fading : From minorella by its larger size, different wing form and less diffused fuscous dusting. From fumer- ella by its decidedly narrower wings, smaller size and paler coloration. Expanse 17.0-18.0 mm., 0.68-0.72 inch.
Hab— Tex. (Dallas).
I have examined the type specimens in Cambridge Museum. Three of these bear Zeller's green labels, number 1712 : — Dallas, Texas Boll. In all of these veins 3 + 4 are stemmed, 5 arising out of the stem.

Six males and one female in the Nat, Mus. Coll., collected by Mr, Augst Busck, and to whom it gives me pleasure to dedicate this very interesting addition to our fauna.
The above description as far as coloration of wings con- cerns was taken from a male. The female, which appears to be somewhat rubbed, presents an almost altogether different appearance, with scarcerly a trace of ferruginous coloring ; a suffused grayish-fuscous, a trifle darker along both margins and apical portion ; a fine more or less interrupted black line in the fold, edged above by whitish scales, some short, black- ish lines in basal third near each margin ; no evidence of a fascia, the discal spots of the male are replaced by some ir- regular blackish dots ; spots at end of cell distinct, Hind- wings darker, with very little lustre. Both wings are rela- tively wider than in the male, it expands 20.0 mm.
The coloration and pattern of marking of the forewing in the c? d1 . appears to be variable in intensity and extent. Vein 3 + 4 of hindwing connate or very short stemmed, in one wing at least, separate ; vein 5 free in all.
13. H. sciaphilella Zell.
Dr. Zeller describes this species as follows : " Alis ant cinereis, area basali postice abrupta macsulaque costse triangula interins albido — marginata nigricantibus, pari punctorum supra angulum internum nigra, cf."
" Head and thorax gray, somewhat shining. Antennae gray, excised above the basal joint, excision with obliquely truncated scale tuft. Palpi as long as the thorax, slender, ascending, the second joint closely scaled, grayish-fuscous, white at the apex, terminal joint half the length of the second, pale at apex. Thorax beneath white. Legs fuscous, apices of tibiae and tarsi whitish ; posterior tibiae compressed, both edges with fuscous hairs, apices and a white oblique spot about the middle externally, white, spines white. Abdomen short, gray, anal bush whitish. Forewings three and one-half lines long, rather narrow, of about equal width to tornus. Ground color pale gray, thinly dusted with blackish scales, basal fifth blackish, terminating in a straight, though not sharply defined line, before the middle is a large triangular costal spot, sharply defined and edged with white towards the base, attaining the fold, ill-defined externally, opposite to this is an ill-defined dorsal spot, forming thus an angulated though interrupted fascia, the angle resting upon the fold and the fascia becoming narrower towards

the dorsal margin and margined with white in its costal portion ; two dark spots at end of cell and a nebulous spot on dorsal margin beneath ; cilia gray. Hindwings narrower than the forewings, not acutely pointed ; cilia gray with yellowish tint, with yellowish basal line."
Identical with H. triangularisella Ch. Have examined both types in the Cambridge Museum, and there is no doubt about their identity. Zeller's type came from Texas, while Chambers' came from Kentucky. The latter is an unspread specimen, type label 1550 in Chambers' handwriting. The wings of the left side are wanting.
Zeller's type of sciaphilella, a male in good condition, presents a peculiar dimorphism of the two hind wings, left hindwing eight veins, 3+4 short stemmed, 5 connate with stem, right hindwing seven veins — Blastobasis, this then very readily explains the confusion hitherto existing as to the position of this species. According to the law that the pres- ence of a quality is dominant over its absence ; or, that a retrogression or retarded condition is recessive to the more developed condition, enforces the reception of this species into the genus Holcocera.
The type bears the green label in Zeller's handwriting, number 1713, Texas, Dallas, Boll.
I add the following notes to the original description :
Palpi long, terminal joint slender, three-fourths the length of the second, the latter fuscous within and without, apex white, the terminal joint sprinkled with fuscous scales. Front grayish-white with some lustre, vertex fuscous. Basal joint of antenna? one-half longer than wide, white, dusted with fuscous, pecten long, fuscous ; shaft of antennas fuscous above, paler beneath, excised above the base, tuft within the excision truncate, scarcely pubescent. Thorax grayish- white suffused with fuscous, particularly on the disc, with some faint lustre. Forewings moderately wide, not acutely pointed ; ground color pale grayish-white, speckled and marked with fuscous-brown, having a purplish lustre, as follows : Base, limited externally by a nearly straight line, followed by a white fascia, narrowed almost to a point on the costa and angulated externally, summit of angle in the fold, shaded in costal portion by a very pronounced nearly triangular patch, which becomes effaced outwardly ; a much less pronounced opposite dorsal patch ; no spots in middle space, two spots at end of cell, a pro- nounced patch on dorsal margin below end of cell, and a larger but less distinct one a little beyond the end of cell, on costal margin ;

Cilia pale gray. Hindwings to the middle, but little narrower than the forewings thence gradually narrowed to a distinct, though not elongated point, very pale gray, with some lustre, paler towards the base. Cilia pale yellowish. Underside of forewings unicolorous, gray ; dorsal margin paler. Hindwings same color as upper side, somewhat darker along the costal margin.

Two males in Cambridge Museum labeled livorella, but not in Zeller's handwriting, Dallas, Tex. Boll. Zeller states (palpi): "third joint one-half the length of the second," whereas it is nearly as long. Antennas deeply excised above the base, excision with truncated tuft, cilia short. The fore- wings can hardly be called narrow, costa somewhat arched from the base, white, lightly dusted with fuscous, the latter more condensed in basal portion with an ill-defined dash above the fold. The subcostal spot near the base, mentioned in the description is not noticeable, unless it is the supra- plical dash mentioned here ; beyond the darker basal dusting is a relatively wide irregular fascia, shaded externally, espe- cially in costal portion by some dusting. Hindwing as wide as the forewing, pointed ; cilia under 1. Abdominal seg- ments light fuscous, fringed with silvery white scales, anal bush white.

in the male. Thorax grayish-white, more or less dusted with fuscous. Forewings moderately wide, costa slightly retuse beyond the middle, acutely pointed ; ground color white, more or less densely dusted with fuscous-brown, the dusting condensed into patches, so arranged as to leave an oblique fascia of the ground color, commencing at the costa at one-third and extending to the dorsal margin at two-fifths ; before this fascia is a large nebulous patch on the dorsal margin, enclosing — sometimes — a large white spot resting on the margin, the costal portion of the fascia is heavily shaded without, before the middle is a small discal spot and two others, distinct, at end of cell ; beyond these are several small patches within the dorsal margin, and a row of spots along the base of the cilia, the latter grayish-white. Hindwings nearly as wide as the forewings, costa scarcely retuse, acutely pointed, silvery white, lightly dusted with fuscous; cilia 1. Abdomen sordid white, dusted with fuscous. Underside of body sordid white. Legs white, dusted with fuscous, ends of tibiae and median band, as well as apices of tarsal joints, paler. Expansion 13.0-16.0 mm., 0.52-0.64 inch.
Hab. — Cal. (Pasadena, Alameda County, Los Angeles).
Introduced from Australia. Larva lives on Icerya and Leuconium oleae. This is the type of Cynotes Wish. Veins 3 + 4 of hindwing short stemmed or connate, 5 generally free or subconnate with stem of 3 -|- 4.
17. H. malig'emmella Murtf.
This species, which at the time of its appearance, gave rise to the apprehension of becoming an orchard pest, is described by Miss Murtfeldt as follows :
"Alar expanse 14 to 15 mm. General color satiny brownish buff with slight opalescence, and more or less leaden shaded on thorax, wings and body. Head buff, densely and somewhat shaggily scaled. Eyes prominent, purple black. Antennae two-thirds as long as wings; basal joint conspicuously long and stout ; second joint also long, with the inner side peculiarly excavated. Palpi (labial) long, recurved with short, almost concealed basal joint, long slightly thickened second joint and slender, tapering terminal. Thorax broad ; patagia rather large, all anteriorly bordered with leaden gray. Forewings varying in color from almost clear buff to buff so interspersed with the darker scales as to produce a ' smudged ' effect ; a small but distinct black discal dot and a group of five smaller, less clearly defined ones at the base of the terminal third, constitute the ornamentation. Hindwings rather broad, somewhat paler and more lustrous than the primaries. Fringes concolorous with wing surface, also varying in intensity of the
WM. G. DIETZ, M.D. 43
dark shadings. Body yellowish-gray with bright buff anal tuft. Legs agreeing in color with under surface, tibiae, especially of hinder pair, densely clothed with long but appressed hairs."
Hab. — Missouri.
The larva, about 8 mm. long when full grown, is yellowish- green, head and dorsal part of first segment black, eats into the buds of both flowers and leaves of apple.
A cotype specimen in the Nat. Mus. Coll. scarcely agrees with the description, and still less with the figure as given by Miss Murtfeldt, the latter evidently had been reproduced from a photograph. This specimen presents a basal space, sharply limited externally by an angulated line, the summit of which is a little above the fold. This space is paler, uni- formly grayish-fuscous ; immediately beyond it and a little above the fold is a dark spot ; remainder of wing mottled with fuscous, two spots at end of cell. It rather strongly resembles Hoi. modestella Clem., but lacks the dark patch in the basal space.
Since the foregoing has been written I have been enabled through the courtesy of Prof. Alex. D. MacGillivray, of Cornell University, to examine the apparently unique type- specimen now the property of the above-mentioned institu- tion. It is a male, faded and in poor condition, right fore- wing wanting, labial palpi ditto. Head ochreous. Antennas moderately thick, excision above the basal joint not pro- found; cilia fully \. The "leaden-gay" border of anterior thoracic margin is rather purplish-brown, well marked, and rather behind the anterior margin, the latter being like the remainder of the thorax, ochreous. Forewings rather short and broad, very obtusely pointed, without paler basal space ; sordid ochreous-gray, suffused with somewhat darker patches, discal spot small, though distinct ; two spots at end of cell, the lower one larger, triangular, and distinct, in line with these two spots, equidistant, and above is another small spot, a trifle beyond these and within each margin is another small dot. These five spots are spoken of in the description as the base of the apical third, and are distinctly recognizable. Hindwings almost as wide as the forewings, grayish dusted

The specimen has the following labels : " Type, Holcocera maligeminella Murt., Nothris maligemmella Murt. ; Columbia Mo. 12, July 189; Stedman Coll."
Veins 3 + 4 of hindwing short stemmed, 5 subconnate with stem. The forewings of this species are more obtuse than in any other of our North American Blastobasidae. 18. H. gilbociliella Clem.
Dr. Clemens describes this species very shortly as follows :
" Forewings pale yellow, with a dark dot in the middle of the wing, and slightly dusted with fuscous towards the apex. Hindwings pale ochreous-fuscous. Antennas dark ochreous. Head and tibial palpi yellowish. The forewings of the female are more dusted with fuscous than those of the male."
The antennae are thickened towards the base. In the male ciliate, cilia a trifle over \, excision not deep, scale tuft ob- liquely truncate. Labial palpi long and slender, terminal joint of nearly equal thickness, pointed, about three-fourths the length of second joint. Hindwings as wide as the fore- wings. Anal bush and legs pale yellowish or sordid white. Expansion 11.0-15.0 mm., 0.44-0.6 inch.
Hab. — Atlantic States.
The type, a male, in the Clemens' collection at the Acad, of Nat. Sciences, Philadelphia, in good condition. A female specimen in the Nat. Mus. Collection, three specimens in my own. The dark discal spot in middle of forewing is obsolete in some specimens. Might be confounded with H. melanos- triatella, but aside from the black subcostal streak the antennae are not excised in the male in the latter species.
19. H. funebra n. sp. — Palpi moderately robust, not reaching above the head, second joint dark fuscous-brown, somewhat thickened towards the apex, terminal joint attenuated towards the apex, two- thirds (c?1) or three-fourths (9) the length of the second, fuscous, speckled with whitish within. Antennae of moderate thickness, fus- cous-brown, with a faint sheen, slightly pubescent and denticulate within, not excised above the base in the male. Head and thorax fus-

cous, intermixed with grayish scales, with a faint greenish cupreous lustre. Forewings of moderate width, costa approximately straight for two-thirds its length, thence gradually depressed towards the obtusely pointed apex ; ground color fuscous, suffused with brown and intermixed with hair-. ike pale grayish scales, with a purple-brassy lustre in certain lights ; the darker coler prevails, especially in costal and apical portion of wing, and along the dorsal margin ; before the middle and a littfe above the fold is a dark, elongate spot, two others, larger and well marked at end of cell ; cilia gray, sprinkled in basal half with fuscous and grayish scales. Hindwings as wide as the fore- wings, costal margin depressed from one-third its length, not acutely pointed, fuscous, especially towards the apex ; cilia grayish-fuscous, a tifle over 1. Abdomen above fuscous, anal bush concolorous, under- side of body grayish-fuscous. Legs grayish, more or less suffused with dark brown, tarsal joints slightly paler at apex. Underside of fore- and hindwings dark fuscous. Vein 5 of hindwing connate with stem of 3 + 4, the latter one-half the length of vein 4. Expansion 12.0-15.0 mm., 0.48-0.6 inch.
Hab. — Md. (Plummer's Island), Pa. (Hazleton).
Four specimens in the Nat. Mus. Coll. collected by Mr. A. Busck, May, June and July, 1903. A specimen, taken by the writer at light, is without the spots on the forewing. Not distinguishable from H. purpurocomella except by the male antennae, which are not excised, very close to inconspicua Wish.
Var. reductella.
Two specimens in Mr. Kearfott's collection differ from the typical form as follows : Larger size 16.0 and 17.0 mm. ; somewhat paler ; front grayish-ochreous ; head and thorax with scarcely any metallic lustre, the basal third of forewings appears, especially outwardly, a trifle paler ; underside of body and legs much less suffused with dark fuscous. The wings relatively a trifle wider, and the hindwings more obtuse.
Hab. — Manitoba (Aweme).
The variability in the relative position of veins 3, 4 + 5 of the hindwings, find an apt illustration in these two specimens ; one specimen has 3 + 4 scarcely stemmed and almost con- nate with 5 ; in the second specimen, on the right side, 3 + 4 short stemmed, 5 arising from the stem ; left side, 3+4 longer stemmed, 5 connate with stem. To judge from the description this form seems closely related to stygna Wish.

20. H. iucouspicua Wish. — "Antennae pale grayish-brown. Palpi grayish-brown, darkened externally. Head and thorax grayish- brown. Forewings grayish-brown through a profuse dusting, amount- ing to an almost entire suffusion of this color upon a pale cinereous ground ; the only marking indicated is a slight and obscure transverse shade at two-fifths from the base and a reduplicated brownish-fuscous spot at the end of the cell ; cilia pale grayish-brown. Alar expanse 13-14 mm.

Paratype, male, Nat. Mus. Coll.
Hab. — Shasta County (Hatchet Creek), California, July 14-17, 1871.
An obscure and ill-defined form. Have examined the specimen in Nat. Mus. Coll. Veins 3 + 4 of hindwing long stemmed, 5 out of stem of the latter, nearly unicolorous, the spots at end of cell as well as the obscure transverse shade, scarcely discernable. Appears to differ from funebra in the absence of the metallic sheen and first discal spot and the lighter simi-transparent color of the hindwings.
21. H. stygna Wish. — "Antennae pectinate, but not notched; purplish-gray. Palpi purplish-gray. Head and thorax purplish-gray, the tegulae with a distinct coppery tinge. Forewings tawny vinous gray, a purplish sheen strongly expressed at the base of the costa, the middle and outer half of the costa slightly darker than the remainder of the wing ; the commencement of this dark shading extends across the wing to the dorsum, leaving the preceding space outwardly angu- late at the middle, and a paler or more grayish shade ; a redupli- cated shade-spot at the outer end of the cell is very obscurely indicated ; cilia brownish gray, with a slight tawny suffusion. Hindwings brown- ish-gray; cilia pale buff-brownish. Abdomen (missing). Legs brown- ish-gray, with broad tawny tarsal bands. Alar expanse 18 mm. Type, male, in the author's collection;"
Hab. — Mendocino County, north of Mendocino City, Calif, (close to the town), June 3-5, 1871. Unique.
The author compares this species with H. purpurocomella Clem. To judge from the description it should very closely resemble Holcocera dives, var. basipallidella ; the basal space in H. purpurocomella is not paler and angulated externally.

Hindwings pale brownish-gray ; cilia yellowish-brown. Abdomen and legs pale brownish-ochreous. Alar expanse 16-18 mm."
Hab. — Colorado, Loveland, 5000 feet, July and Sept., 1891 ; Denver.
The above is Lord Walsingham's description. Cotypes in the Nat. Mus. Coll. have been examined by the writer. This is the type of Catacrypsis Wish. The palpi are equal in both sexes. Hindwings as wide as the forewings, costal margin nearly straight, depressed towards the apex, the latter rather obtuse. Veins 3 + 4 of hindwing long stemmed, 5 from about the middle of the stem.
The peculiar ochreous-brown color distinguishes this species from any other of our North American forms except borea- sella, from which it is distinguished by its smaller size and the absence of longitudinal lines and the patch of whitish scales in the basal space. From H. nana it differs at once by its much larger size.
24. H. nana n. sp. (Plate III, fig. 24.)— Head, basal joint of antennas, thorax, and palpi pale ochreous- white, the latter long and slender, extending considerably above the front, terminal joint slender, nearly as long as the preceding, dusted externally, especially the termi- nal joint, with fuscous. Antennal shaft grayish, dusted with fus- cous. Forewings rather narrow, costal margin slightly retuse about the middle third, pale ochreous, suffused in patches with fuscous hav- ing a faint purple lustre, as follows: a large, ill-defined oval patch in basal fifth, a triangular patch on both the costal and dorsal margins at one-fifth, curved outwardly and forming an ill-defined angulated fascia, on the inner margin of the costal spot, and above the middle is a well marked blackish spot, two similar spots at end of cell, a patch just beyond the middle of the costa and one at about four-fifths, a patch on the dorsal margin, just beyond the end of cell , a series of dashes along the base of the cilia, apical portion of wing more or less densely dusted with pale fuscous ; a dark purple-brown spot at base of costa, extreme

In coloration this species resembles somewhat chalcofnm- tella, but aside from size is of different wing shape, I place it here provisionally. Veins 3 + 4 of hindwing long stemmed, 5 out of stem of 3 + 4.
25. H. elyella n. sp. (Plate III, fig. 25).— Palpi white, more or less densely suffused with dark brown, except apex of second joint, long, and especially the terminal joint, slender, the latter about two- thirds the length of the second. Head sordid white, front smooth scaled, somewhat shining, vertex slightly rough. Basal joint of antenna? one- half longer than wide, sordid white, pecten of closeset scale like seta?, gives the joint a very broad appearance, shaft light fuscous, not excised above the basal joint, finely pubescent and denticulated beneath (male) . Thorax sordid white, tinged with fuscous.

Fifteen specimens in my own collection and two in the Nat. Mus. Coll. — all males — are before me. All were col- lected in July and August. Most of the specimens are more or less worn or rubbed, and in these the markings will fall short of the above description and the figure. It gives me pleasure to name this very distinct species after Mr. Charles R. Ely, of Washington, D. C, who collected all my Con- necticut material, and to whom I consider myself under great obligation for this and much other material. In thirty hind- wings examined vein 5 was free in six, in these the stem of 3 + 4 was short, among the remaining 5 was connate with the stem, or in a few instances arose from the latter near its origin.
26. H. insulatella n. sp. (Plate III, fig. 26) .—Palpi, head, basal joint of antennae and thorax sordid white, lightly dusted with pale fus- cous. Palpi rather short and stout, the second joint more densely dusted externally, nearly twice the length of the terminal joint, the latter acutely pointed, scarcely dusted at all. Basal joint of antennae nearly twice as long as wide, feebly curved, pecten of long, not closely set setae, stalk slender, simple, grayish-fuscous, scarcely pubescent (cf). Posterior margin of head more distinctly whitish. Thorax anteriorly, except the patagia, infuscate. Forewings elongate, acutely pointed, costa approximately straight from the base to the apical fourth ; ground color white, lightly suffused with dark fuscous, the latter prevailing more in the costal and apical portions of the wing, at one-third from the base is a heavy costal spot extending somewhat backward, then sends a narrower line obliquely backward, a spot less distinct but similar to the costal one, but a little nearer the base, on the dorsal margin, extending slightly backward and from which proceeds a nar- row curved line which with the line from the costal spot forms an acute angulated fascia, the summit of the angle is a little nearer the costa than the dorsal margin, and which, viewed from the base re- sembles somewhat the letter W, at the end of the cell are two large, dark fuscous spots, and between the lower one of these and the angle of the fascia is a series of four or five unequal spots, the elongate oval space, enclosed between these and the rather densely speckled sub- costal space, is almost white ; cilia sordid grayish-white. Hindwings as wide as the forewings, costa not retuse, depressed towards the apex, latter acute, grayish-white, lightly dusted with fuscous externally;

Forewings moderately wide, pointed, ground color whitish, finely speckled with dark fuscous and heavily overlaid in its outer two- thirds of costal portion with dark fuscous-brown, basal space limited externally by a very conspicuous, evenly curved fascia, of the same color, shading off gradually outwardly, this fascia begins at one-third of costal margin and ends at one-fourth of dorsum ; basal portion of wing rather densely dusted with dark fuscous ; immediately beyond the fascia and connected with it are two longitudinal spots, one above, the other beneath the fold, two distinct spots at end of cell, beyond these the wing is rather densely dusted and speckled with fuscous ; cilia gray, dusted in basal portion with white and fuscous scales. Hindwings under 1, gradually narrowed from the base, obtusely pointed, costa retuse in outer half, gray, dusted with fuscous, espe- cially along the margins. Abdomen above grayish fuscous, with some lustre, anal bush grayish-ochreous ; beneath, dark fuscous in basal portions, gray toward the extremity. Underside of thorax dark fus- cous-brown.

Two specimens in the Nat. Mus. Coll., and a male in my own. The latter has but one forewing left, the ground color is white with scarcely any sprinkling of dark scales, the markings less pronounced than in the female. A female specimen in my collection from Stockton, Utah, collected by Mr. T.

Antennae of moderate thickness, not excised above basal joint, latter pale yellowish ; pale fuscous above, grayish beneath, obscurely denticulate and pubes- cent beneath. Head sordid white, speckled with fuscous scales and without lustre. Thorax sordid white, broadly margined in its entire width anteriorly with deep purple-brown. Forewings moderately wide, costa approximately straight three-fourths its length ; ground color gray, sprinkled with whitish scales, the latter more aggregated in the basal third which is limited externally by a sharply angulated line, the summit of the angle much nearer the costa than the dorsal margin and limited by a distinct black spot ; besides the white there are dark fuscous scales forming spots or patches, distributed as follows : a patch at base of costa, a distinct but not sharply defined spot at one- third, and a very feeble one about middle of costa, in the basal space immediately above the fold is a longitudinal dash, and immediately beneath it, but a trifle nearer the base another, and beyond it, in the fold and beginning on the angulated line another dash, on the disk are some scattered fuscous dots and dashes, two spots at end of cell ; an outwardly angulated, not well defined fascia in apical part of wing, a series of dashes along base of cilia.

30. H. morrisoni Wish. — " Antennae with moderate pecten ; pale brownish-ochreous. Palpi brownish-ochreous. Head and thorax gray- ish-brown, with paler speckling. Forewings rather narrow, elongate, not widening outwardly ; base white, with grayish-brown suffusion, especially around the margins ; a brownish shade at the base of the costa, a darker streak in the basal third of the fold, diffused and diluted to the nexus ; beneath it a triangular brownish-fuscous dorsal patch arising a little before the middle, directed obliquely outward and end- ing obtusely on the cell at about one-half the wing length ; beyond it a pair of brownish-fuscous spots at the end of the cell, and a few ill- defined similar spots around the apex and termen ; cilia grayish-brown. Hindwings shining, pale brownish-gray; cilia pale brownish-ochreous. Abdomen and legs pale brownish-ochreous. Alar expanse 17 mm."
Hab. — Arizona. Type. — Male, Mus. Walsingham.
"A narrow winged species, differing much in appearance from any already described (Walsingham), and quite unlike such exponents of allied genera as I have before me."
The above is Lord Walsingham's description with com- ments. I have nothing to add ; unknown to me. The peculiar dorsal patch should lead to the recognition of this species. 31. H. fluxella Zell.
Described as follows :
" Minuta, antennis crassiuseulis, supra articulum basalem squamis ampliatum, non excisis ; alis aut cinereis, striga ante mediam fracta, albida, exterius nigricanti — marginata, puncta disci punctisque duabus geminatis veuag transversa^ coalescentibus nigris ; posticis lanceolatis.
" Agrees nearly with H. fractilinea in markings, but is smaller with narrow hindwings and more slender abdomen, the antennas, how- ever, are not excised at the base. Palpi more slender than by fracti- linea, bend upwards, as long as the thorax, light gray dusted with fus- cous externally, third joint less than one-half the length of the second, more slender and pointed. Legs pale ochreous-white ; posterior tibiae rough haired, hind tarsi pale fuscous externally, joints pale at apex. Abdomen slender, sides of posterior segments with pale yellowish hairs, anal bush of same color. Forewings two and one-half lines long, gray, darker along the margins; transverse line angulated above the fold, margined externally with dark fuscous, before it and in the fold is a small black dot, and beneath it a short dark line, and behind it, im- mediately above the angle, is a sharply defined black spot ; two con- fluent spots at end of cell, and beneath these a spot on the posterior margin ; a line of non-confluent black spots at base of cilia. Hind- wings about one-half the width of forewings, lanceolate, sharply pointed with distinct anal angle, c?. Texas."
WM. G. DIETZ, M.D. 55
The type, numbered 1711, is in the Cambridge Museum. It bears Zeller's green label and name in his own handwrit- ing— Blastobasis fluxella Z., Dallas, Texas, Boll.
The third palpal joint is certainly more than one-half the length of the second ; palpi not very slender and divergent. Basal joint of antennae broad, not longer than wide ; pecten shorter than width of joint. Head and thorax sordid grayish- white, the latter purplish-brown anteriorly, this color extend- ing across the patagia to'base of costa of forewings, the latter moderately wide, not acutely pointed, base fuscous, the black dot in basal portion of fold is not evident ; the angulated fascia is nearly at two-fifths the wing length, beyond the fascia, the wing is more densely dusted with fuscous, just beyond the spots at end of cell is a somewhat conspicuous costal and dorsal spot ; cilia grayish-white with scattered white scales. Hindwings nearly as wide as the forewings, in basal portion, strongly narrowed towards the apex, the latter pointed ; cilia a trifle over 1. Veins 3 + 4 long stemmed, 5 connate with stem. In a specimen in Lord Walsingham's collection vein 5 of hindwing arises out of stem of 3 + 4, but as elsewhere stated, this is a variable condition and of no diagnostic value. 32. H. clemensella Ch.
Relative to this species Mr. Chambers expresses himself as follows :
" H. chalcofrontella Clem, is so variable a species that it is possible this may be a variety of it ; but it is not one of the described varieties.
" Whitish, dusted lightly with dark purplish-brown, the dusting dense on the second joint of the palpi. There is a purplish-brown patch at the base of the costa, a small one about the middle of the costa, a small one opposite to it on the fold, a small one on the disc opposite the space beween the other two and at the end of the disc, and a row of small dots around the apex at the base of the cilia. Alar expanse one-half inch. Season, August."
I have carefully examined the type in the Cambridge Museum, and have no hesitancy in pronouncing this species absolutely distinct from chalcofrontella and its varieties. The specimen, a male, is unspread, wings of left side wanting, markings of right forewing difficult to discern on account of

oiliness. The following notes taken may assist in the recog- nition of this species :
Palpi sordid white, rather stout, scarcely reaching to the lower border of the insertion of the antennae, apex of second joint pale. Head sordid white, with some sheen, smooth scaled, finely speckled with pale fuscous. Basal joint of antennae sordid white, rather broad, one-half longer than wide, pecten setaceous intermixed with some scales, stalk grayish-fuscous, not excised above the base, simple, mod- erately robust, neither ciliate nor pubescent. Thorax sordid white, and like the head, speckled with pale fuscous, Forewings elongate — more than in chalcofrontella , white, evidently dusted with fuscous, basal part of costa dark purple-brown, at one-fifth, there is a transverse costal spot reaching to the fold, but more distinct on the costa; apparently, there is an outwardly convex, rather wide fascia at one-third, but whether entire or not could not be determined, wider at the dorsal margin and equidistant from the base at both margins, just before the middle and nearer the costal margin is an elongate spot, two smaller dots at end of cell ; cilia grayish, speckled with white and fuscous scales, a dark line along the periapical margin but separated from it by a pale line. Anal brush pale ochreous. Underside of body and legs grayish- white, the latter suffused with fuscous; end of tibiae and tarsal joints paler. Venation not determinable.
The specimen bears Chambers' label, " Clemensella; Ken- tucky, Chambers."
33. H. irenica Wish. — "Antennae, female, brownish-gray; basal joint with strong pecten, paler. Palpi grayish-white, median joint grayish-brown externally nearly to the apex; terminal joint also sprinkled with brownish-gray. Forewings grayish-white, with brown- gray sprinkling, especially on the outer two-thirds of the costa and on the dorsal and apical portions of the wing ; a patch of this at the base of the costa, mixed with some ferruginous scales ; a similar patch before the middle of the costa exhibiting more of the ferruginous color- ing, which is diffused downward to the fold, touching the inner ex- tremity of an elongate-ovate blackish-brown discal spot, beyond which, at the end of the cell, are two smaller spots of the same color, which is also faintly reproduced in a diffused patch or cloud on the dorsum beneath them and on the costa beyond them ; cilia hoary grayish. Hindwings shining, yellowish-gray, with pale brownish- ochreous cilia. Abdomen whitish-gray. Legs whitish, shaded with brownish-gray on their outer sides Alar expanse 20 mm."

The author makes no further comment. A specimen in my possession from the Hulst collection and received from Prof. John B. Smith, agrees fairly well with the above de- scription. Locality, Washington territory.
34. H. illibella n. sp. (Plate III, fig. 30.)— Palpi of moderate thickness and rather short, scarcely attaining to middle of front, gray, more or less densely overlaid with fuscous scales, especially on second joint, extreme apex of second and terminal joint whitish, the latter short, scarcely one-third the length of the second (cf). Antennas moderately thick, gray, basal joint broad and short, pecten of close- set setae, shaft dusted with fuscous, especially towards the apex.

Ex- panse 12.0-13.0 mm., 0.48-0.52 inch.
Hab. — Md. (Frederick). Three males in my collection.
An obscurely marked form. In one specimen the spot in middle of forewing is wanting, in another the costal spot at two-fifths. The terminal joint of palpi is strikingly short. Veins 3 + 4 of hindwing long stemmed, 5 out of stem near its base.
35. H. creseentella n. sp. (Plate IV, fig. 31.)— Palpi of mod- erate length, terminal joint slender, acutely pointed, two-thirds the length of the second joint, white, sprinkled within and without with dark brown scales, leaving a rather broad ring at the apex of the second and of terminal joint white.

Hab.— Utah (Stockton).
A female specimen, collected by Mr. Tom Spalding in my collection. Vein 5 of hindwing connate with stem of 3 + 4.
Var. aimulipes.
A specimen, female, from the Baboyquivaria Mountains, Ariz., in my collection, measuring 13.0 mm. agrees well with the type in markings, but differs by the hindwings having a brassy sheen and the cilia are more tinged with yellow. Legs white, tibiae with two broad fuscous bands, leaving the ends and a band in the middle white, apices of tarsal joints con- spicuously white, rest fuscous. Vein 5 of left hindwing con- nate with stem of 3 + 4, distinctly from the stem in right hindwing.
36. H. spretella n. sp. (Plate IV, fig. 32.)— Palpi, head, basal joint of antennae and thorax grayish-white, tinged with ochreous. Palpi reaching to upper margin of the antennal insertion, terminal joint two-thirds the length of the second ; speckled with fuscous scales, more densely without. Antennas grayish-fuscous, not excised above the base, finely denticulate and shortly ciliate beneath in the male, a little more robust than in the female; basal joint rather small, pecten gray. Thorax and patagia suffused with fuscous anteriorly. Fore- wings rather elongate, costal margin approximately straight from base to apical fourth ; ground color white, rather densely speckled with dark brown from basal third outwardly, the dark scales most pro-

nounced in costal part of wing, and least along the middle of the disc, on the costa near the base is a dark fuscous patch, from which extend a transverse spot to the fold, the remainder of the basal space is thinly speckled with pale fuscous, at one-third is a nearly straight fuscous fascia, rather broad but not sharply defined externally, within this fascia and on the fold is a darker spot, another more distinct spot im- mediately beyond the fascia and a little nearer the costa, another elon- gate spot beyond the middle and a little above the fold, at the end of the cell are two somewhat coalescent spots, from each of these a dark shade extends to respectively the costal and dorsal margins ; cilia grayish-white. Hindwings about as wide as the forewings, acutely pointed, costa scarcely retuse outwardly, whitish, lightly dusted with fuscous, with some lustre ; cilia a trifle over 1, pale gray with pale yellowish sheen. Abdomen grayish -fuscous, anal tuft ochreous. Underside of body silvery white, shining, abdomen suffused with fus- cous. Legs white, anterior thickly suffused with fuscous, middle and posterior, especially the latter, much less so, oblique spot and apices of posterior tibia? and apices of tarsal joints pale. Expanse 16.0-21.0 mm., 0.64-0.84 inch.
Hab. — Ariz. (Williams, Phoenix).
Four specimens, two males and two females, are before me. Three of these in the Nat. Mus. Coll. from Williams, Ariz., measure 16.0 mm., or a trifle over, while the fourth, a female from Phoenix, in my collection, measures 21.0 mm., but aside from its larger size and more pronounced mark- ings, it does not differ. The transverse costal spot near the base and the two distinct spots in the mesial space, dis- tinguish this species from any other. Stem of veins 3 + 4 of hindwing about half the length of vein 4, 5 connate with stem. A specimen from Vowell's Mill, La., and another from Alabama (without locality) in my collection, may be- long here ; their markings, however, are indistinct, and do not permit a definite opinion. Two other specimens from Williams, Ariz., also in the Nat. Mus. Coll. measure only 14.0 mm., and do not have the basal space paler as in the typical form.
37. H. nrsella Wish.— "Antennas with pecten, but without notch ; pale brownish-ochreous. Palpi brownish-gray externally, dirty whitish on their inner sides. Head and thorax bone-whitish, the latter tinged brownish-gray anteriorly. Forewings bone-white, much suffused and sprinkled with brownish-gray, overclouding the costa as well as the

Alar expanse, 18 mm. Hindwings pale gray, with a slight brownish tinge ; cilia pale brownish-ochreous. Abdomen grayish. Legs pale brownish-ochreous. ' '
Type. — Male, in the author's collection.
Hab. — Shasta County, Bear Creek, California, July 27-28, 1871.
The above is Lord Walsingham's description, from this and his reference to ijiconspic.ua we may infer that the general effect and appearance of this species is rather grayish-fus- cous than sordid white.
38. H. punctiferella Clem. (Plate IV, fig. 33).— Labial palpi yellowish white, dusted externally with fuscous, apex of second and of terminal joint white, the latter two-thirds the length of the former. Head sordid white with yellowish tinge. Antennae yellowish-brown, not excised above the basal joint (d1), the latter one-half longer than wide, pecten grayish-white. Thorax sordid gray, with a yellowish- brown tinge. Forewings rather narrow, costa approximately straight, apex acute ; ground color whitish, dusted with brown, the dusting more condensed along the margins, especially the costal and in apical portion of the wing, a subquadrate dark brown costal spot at one- third, opposite this but a trifle nearer the base, is a larger, irregularly triangular patch, the apex of which extends beyond the fold, but does not reach the costal spot, within the dorsal spot is a plical dash, and behind it and obliquely above is a distinct, longitudinal spot before the middle, two distinct spots at end of cell and midway between the lower one of these and the discal spot is a distinct, longitudinal spot on the posterior median vein, a row of spots along the apical margin ; cilia gray with some scattered white and brown scales. Hindwings a trifle under 1, costa scarcely refuse, apex pointed ; gray, lightly dusted with fuscous, with yellowish tinge ; cilia concolorous with pale basal line. Abdomen above, underside of body and legs grayish, dusted with fuscous, anal bush pale ochreous. Expanse 11.0-13.0 mm.

Dr. Clemens' description of this species is defective, as he does not mention the marginal spots at one-third of the wing length. He described it as a Gelechia. Vein 5 of hindwings connate with or narrowly separated at its origin from the stem of 3 + 4.
Var. (Hypatima) subsenella. Zell. (Plate IV, fig. 33a.)
The type, a male, is in the Cambridge Museum. It has Zeller's green label, 1716, Dallas, Tex., and name in his handwriting. Consider this form a variety of the above and from which it differs by the darker color of head, palpi and antennae, a transverse costal spot very near the base, and the dorsal spot not extending beyond the fold. The last char- acter may not be a constant one, and also the fact that the type specimen is minus the wings on the left side, a number of specimens in my collection, all taken in my locality agree with this form, except that in all of them the dorsal spot extends beyond the fold, thus agreeing with punctiferella, from which, however, it differs by its general darker colora- tion, the dark costal spot near the base, and its somewhat larger size — 13.0-14.0 mm. — one out of a series of ten, sent to Lord Walsingham for determination, was returned as Hypatima texanella Wish. In five of these specimens vein 5 of forewing is distinctly free, in the others apparently con- nate with stem of 3 + 4.
Var. texanella Wish. (Plate IV, fig. 336.)
Very close to the preceding variety, from which it differs by its somewhat lighter color and a tendency of the plical dash at one-third and the spot on the posterior margin of the cell to become obliterated. The fascia at one-third is less angulate. The author, in fact, does not mention these char- acters in the description, but in one wing — slide specimen — from a cotype in the National Museum Collection, which is before me, both are present, though not marked. Expanse 14.0-16,0 mm., 0.56-0.64 inch.

In " Annerkung 2 " to his description of Hypatima subse- nella, Zeller refers to two male specimens, which he com- pares with and doubtfully refers to the last named species. I have examined these specimens carefully, and entertain no doubt of their being distinct.
Palpi, head, basal joint of antennas and thorax bony white. Third joint of palpi two-thirds the length of the second joint, the latter roughened with scales beneath, dusted with fuscous. Basal joint of antennas scarcely longer than wide, pecten gray. Vertex and anterior part of thorax dusted with fuscous. Form of forewings like those of subsenella, ground colox a sordid white with a yellowish tint, dusted lightly with fuscous ; basal space limited externally by an interrupted, irregularly angulated line, a dark nebulous spot at base of costa, a dark line on the fold before and another crossing the angulated line, an ill-defined spot on both the costal and dorsal margins at one-third, first discal spot just beyond angle of line, somewhat elongated, two distinct spots at end of cell, and another elongated spot on the poste- rior margin of cell, a distinct and rather conspicuous patch on middle of costa, a nebulous spot on both margins just beyond the cell, and a row of dots along base of cilia ; cilia gray, speckled with white and fuscous scales and two or three paler lines. Hindwings not as wide as forewings, costa retuse outer two-fifths, pointed, grayish-white, dusted with fuscous ; cilia over 1 ; veins 3-f-4 stemmed, 5 free (in one wing vein 5 appears to be connate with stem 3 + 4).

Types in Cambridge Museum. I name this species after the late Prof. P. C. Zeller in consideration of his valuable contributions to our knowledge of North American Micro- lepidoptera. The specimen which he refers under " Amer- kung 1 " to his subsenella belongs to Valentinia. In his refer- ence— Amerkung 2 — Zeller does not mention the spot on the middle of the costa, but mentions a dark line or streak near the base and within the dorsal margin, this character I could not discern in either of the specimens.

Fore- wings narrow, pointed, costa approximately straight, white, very lightly and inconspicuouly dusted with pale brown here and there, scarcely clouding the ground color; markings dark brown, as follows: basal part of extreme costa, a subcostal spot near the base, a short streak in basal part of wing immediately beneath the fold, a streak in the fold beginning at one-third, an elongate spot obliquely above (first discal), a small spot at lower margin of cell at three-fifths of wing- length, two spots at end of cell, a strongly angulated line in apical part of wing, commencing in a nebulous spot within the costal margin and a little beyond the cell and ending in a similar spot within the dorsal margin, a row of dots along periapical margin ; at one-third of the winglength is a diffused, ill-defined costal and dorsal spot ; cilia gray, sprinkled with white scales. Underside fuscous. Hindwings about as wide as the forewings, rather acutely pointed, costa slightly retuse in outer half ; grayish-white, very slightly dusted with fuscous ; cilia over 1, pale gray, yellowish towards the base. Abdomen above and beneath white, anterior portion of upper segments brown, anal bush yellowish-white. Underside of thorax and legs silvery white, tinged with reddish fuscous.

Four specimens from fhe Nat. Mus. Coll. and two in my own are before me. Conspicuous by its white color; mark- ings variable in extent. In the Massachusetts specimen (Nat.

Basal joint of antennae yel- lowish-white or grayish, of moderate length and width, pecten of closeset bristly hairs, shaft grayish-fuscous, not excised above the base. Thorax grayish- white, speckled with pale fuscous. Forewings narrow, pointed, ground color white, overlaid with grayish-fuscous as to almost entirely conceal the ground color except in basal third, the latter limited externally by an acutely angulated line, the angle being nearer the costal margin ; this space is less suffused with grayish-fuscous, the latter more marked along the margins and extreme base, and a less distinct patch in the middle along the fold, ending before angle of fascia in a more or less distinct spot. A dark semi-oval spot at costal end of the angulated line, and an ill-defined one at the dorsal end of same; just beyond the summit of the angulated line is a strongly marked dark and somewhat elongated spot, two equally well-marked spots at end of cell, and before the lower one of these, on the posterior margin of the cell, is a more or less elongated, very distinct spot, of the remainder of the wing, the darker coloring predominates more along the margins and in apical part of wing ; cilia grayish-white, speckled in basal half with grayish-white scales. Hindwings nearly 1, costa scarcely refuse, dorsal margin feebly curved at tornus, not very acutely pointed at apex, grayish-white, suffused with pale fuscous ; cilia grayish, over 1.

44. H. melonostriatella n. sp. (Plate IV, fig. 38.)— Palpi somewhat robust, of moderate length, sordid white, dusted with fus- cous. Head, basal joint of antennae and thorax white, speckled with pale brown scales. Basal joint of antennas one-half longer than wide, pecten long, of closeset whitish setae ; shaft grayish-fuscous, shortly ciliate and denticulate beneath not excised above base (male). Fore- wings somewhat elongate, pointed, ground color whitish, dusted with pale reddish-brown ; the dusting more marked along the margins, and especially so in apical part of wing, where it is intermixed with fus- cous ; a spot at extreme base of costa, costal margin for about one-third its length, a streak on basal portion of anterior median vein, extend- ing somewhat along vein 11, a somewhat elongated spot before the middle and two spots at end of cell, of which the upper one is longer, dark blackish-brown ; cilia pale gray, speckled with pale reddish- brown and whitish scales, with two or three pale lines. Costo-basal portion of underside of wing infuscate. Hindwings a trifle narrower than the forewings, costa retuse beyond one-third, apex rather acute, grayish-white, lightly touched with pale brown, especially along the margins; cilia a little over 1, pale gray with pale basal line. Basal portion of abdomen above ferruginous, remaining segments of same color, fringed with sordid white scales ; anal bush sordid white. Underside of thorax silvery white, abdomen pale yellowish-white. Legs white, dusted with brown, the latter color arranged in undulat- ing transverse lines on the anterior and middle femora, hind legs more grayish-white, hairs of tibiae long. Expanse 14.5 mm., 0.58 inch.

Seven specimens, all males, in my collection. Two speci- mens in my collection from Frederick, Md. — not in very good condition — probably belong here, but the streak on the anterior median vein is scarcely noticeable, and there is a black dot on the fold at one-third. In five of the hindwings examined vein 5 is distinctly free, while it is connate with

the stem of 3 -4- 4 in the remaining the conditions varying at times in the same specimen. From H. gilbociliella Clem., with which this species might be confounded, it is distinguished aside from structural differences of the male antennae, by the dark subcostal streak near the base.
45. H. interpimctella.n. sp. (Plate IV, fig. 39.)— Palpi slender, especially the terminal joint, the latter two-thirds (male) or three- fourths (female) the length of the second; white, dusted, especially the second joint, except at apex, with blackish scales. Head white, smooth scaled, with some lustre. Basal joint of antennae white, nearly twice as long as wide, pecten setaceous, stalk slender, not excised above the base in the male, equal in both sexes, pale grayish-brown. Thorax white, smooth, lustrous. Forewings narrow, acutely pointed, costa approximately straight from the base for three-fourths its length, white, dusted with pale brown, more so in costal and apical portions of wing, this dusting does not conceal the ground color, no distinct markings, except a row of blackish dots, commencing about the mid- dle of wing length, immediately above the anterior median vein and extending along vein 10, towards, but not attaining the costal margin, basal half of extreme costal margin fuscous, an indistinct elongate spot before the middle and two spots at end of cell, aside from these are some scattered blackish dots ; cilia grayish with scattered white scales, Hindwings as wide as the forewings, costa nearly straight, but little depressed to the acute apex ; pale gray, lightly dusted with pale fus- cous; cilia gray, a little over 1. Abdomen above, underside of body and legs silvery white with lustre, the legs very lightly dusted with fuscous; anal bush white. Expanse 14.0 mm., 0.56 inch.
Hab. — Utah (Stockton), Tom Spalding collector.
Two males and one female in my collection, obscurely marked, except the row of dots above the anterior median vein, which appear to be constant, though variable in extent and distinctness. Veins 3 +4 of hindwings short stemmed, vein 5 free, except in one hindwing, where it is connate with stem of 3 + 4.
EUBOLEPIA gen. n.
Type anomalella. Palpi very long, slender, recurved, the terminal joint about three-fourths the length of the second, front fringed each side with pecten-like hairs ; antennas ( 9 ) slender. Fore- wings moderately wide, widest near the base, gradually nar- rowed to the not very acute apex ; a transverse ridge of raised scales near the base, and a tuft of similar scales before the middle; twelve veins, 7 + 8 long stemmed, remaining

veins free. Hindwings as wide as the forewings, costa scarcely retuse, rather obtusely pointed; cilia scarcely 1; eight veins, 3 + 4 stemmed, 5 out of stem of 3 +4 near its base. Brush of posterior tibiae not strongly marked.
Differs from Holcocera in the presence of scale ridge and tuft on the forewings, and the front fringed each side with hair-like scales, two characters not observed in any other genus of the family known to me. The type is a female. The male in all probability, when discovered, will have the antennas excised above the basal joint. This latter character, together with the scale ridges of the forewing, would show a certain analogy to certain Phycitid genera. One species only.
1. E. auoimxlella n. sp. (Plate IV, fig. 40, 40a.)— Palpi light gray, speckled with brown, especially the second joint externally. Head smooth scaled, except posterior edge of occiput, which is some- what rough haired, scales of front and vertex about equally mixed brown and pale gray, sides of front fringed with closeset pecten-like hairs of a grayish color. Antennas fuscous, basal joint nearly twice as long as wide, pecten long, gray. Thorax fuscous-brown, intermixed with gray scales posteriorly. Ground color of forewings whitish, sprinkled with dark brown scales ; extreme base of costa and a trans- verse dorsal spot very close to the base, blackish brown, at less than one-sixth the wing length is a strongly marked transverse ridge of dark brown scales with an aeneous lustre, at about one-third is an oblique costal streak, slightly convex outwardly, which reaches the fold, where it joins a less distinct dorsal spot, just above the fold and on the streak is a fuft of dark brown scales with aeneous lustre ; beyond the fascia or streak the dark dusting is more pronounced, especially in the costal portion, two dark spots at end of cell, the lower one of these is a trifle nearer the base. Two obscure longitudinal streaks in median space, and an acutely angulated line in apical portion of wing, a row of irregular dots along base of cilia. Cilia gray, with about three pale lines, one near the middle, one near and the other along the outer mar- gin. Underside grayish-fuscous. Hindwings gray, dusted with fus- cous ; cilia gray, with an obscure darker line before the middle. Under- side pale grayish-fuscous. Abdomen grayish-brown, segments edged with white scales. Underside of body pale yellowish-white with some lustre. Ovipositor not exerted. Legs silvery white, the anterior rather densely dusted with fuscous, especially within, tibiae at both ends and median fascia white, hind legs less densely dusted, except tarsi, leav- ing the apices of joints paler. Expanse 19.0 mm., 0.76 inch.

DESCRIPTIONS OF SOME NEW OR UNFAMILIAR NORTH AMERICAN HEMIPTERA.
BY EDWARD P. VAN DUZEE. NEOPHARNUS n. gen.
Closely allied to Pharnus but differing principally in hav- ing the head shorter, the cheeks broader, rounded, approach- ing and almost contiguous at apex above and beyond the tip of the narrow tylus. Antennae longer than in Pharnus, the joints regularly increasing in length. Bucculae elevated anteriorly, its angle subacute and a little advanced, post- eriorly becoming evanescent opposite the middle of the eye. Rostrum attaining the apex of the third ventral segment, first joint but little surpassing the base of the head. Pro- notum broader than in Pharnus, the lateral angles produced in a rounded subnodular lobe directed outwardly; latero- anterior margins narrowly foliaceous-expanded and eroded and armed with a few irregular tentacular teeth. Scutellum and elytra as in Pharnus. Abdomen broad, the connexivum expanded with the apical angles of the segments prominent. Venter with a broad flat carina in a wide shallow depression. Orifices produced in a straight sulcus which terminates ab- bruptly about half way to the margin of the pectus. Meso- sternum and tubercular base of the second ventral segment as in Pharnus. Tibiae sulcate.
This genus differs from Pharnus in having the cheeks pro- duced and almost contiguous before the narrow tylus and the margins of the pronotum laciniate. Type Neopharnus fimbriatus.
Neoplmrims fimbriatus n. sp.
Broad oval with much the aspect of Pharnus inconspicuous H. S. Whole surface punctate and hairy. Margins of the cheeks deeply sinuated before the eyes then almost parallel to the rounded deeply notched apex of the head ; the base of the tylus and a line next each ocellus smooth. Pronotum quite strongly depressed before the middle ;

74 AMERICAN HEMIPTERA.
latero-anterior margins irregularly eroded, with about four filimentous teeth, those at the anterior angles reaching to the front of the eyes; callousities and an indistinct sublateral and median vitta smooth or somewhat calloused ; the surface posteriorly with irregular transverse rugae; the nodular humeri narrowly margined. Scutellum uneven and swollen at base ; the produced apex with a thickened submargin and short median carina. Connexivum broad, deeply notched, the base of the segments swollen. Length 12 mm., width across the abdomen 8 mm.
Color obscure, fulvo-testaceous tinged with ferruginous on the base of the scutellum and the humeral angles. Whole surface punctured with fuscous ; these punctures becoming black in places, especially on the middle of the pronotum anteriorly, scutellum and costal area of the corium. On the lower surface there is a line on either side of the head beneath the base of the antennae, a dot before the eye, a curved line below the expanded margin of the pronotum, a few dots and lines on the pleural pieces and the incisures at the margins, black. Sides of the pleurae and venter strongly irregularly punctured with black, the disk smooth. An anriulus before the apex of the femora, two on the tibiae and a point on the knees fuscous or black ; middle of the antennal joints dusky.
Described from one female taken in Florida and kindly given me by Mr. J. H. de la Torre Bueno. This insect has much the aspect of a small Brochymena, but in its generic characters it agrees entirely with Pharnus except for the pro- duced contiguous cheeks, fimbriate margins of the pronotum and produced nodular humeri.
Rhyparochromus aiigiistatus n. sp.
Form oblong, parallel-sided ; black, with the legs ferruginous and the costal and sutural margins of the corium whitish, forming a dis- tinct M when the elytra are closed. Length 5 mm.
Head black, minutely aciculate ; vertex moderately convex, nearly- square ; cheeks and tylus produced in a blunt triangle, the front of the head less deflexed than in the Europen prcetextatus . Antennae flavo- testaceous ; first joint surpassing the tylus by one-third of its length ; second nearly twioe the length of the first, blackish at tip ; third shorter than the second, piceous becoming pale at base ; fourth scarcely longer than the third, blackish. Rostrum castaneous, attaining the intermedate coxae ; second joint obviously but not greatly longer than the third. Pronotum subquadrate, minutely rugulose ; anterior angles moderately rounded ; sides distinctly and continuously but slenderly carinated, feebly sinuated ; anterior lobe slightly convex, hardly twice the length of the posterior; the latter of a velvety piceous-black, con-
EDWARD P. VAN DUZEE. 75
trasting with the dull black of the anterior lobe ; hind margin rather deeply arcuated. Scutellum black, nearly flat, about equilateral. Elytra short, coarsely punctured ; piceous-black inclining to castane- ous exteriorly on the corium and along the commissural and scutellar margins of the clavus ; the claval margin of the corium slenderly but conspicuously, and the costa more indefinately whitish, thus forming an M-shaped mark when the elytra are closed. Membrane shorter than broad, rounded behind, white aCbase, abruptly pitchy at apex; Beneath black, coxas and legs castaneous or rufo-ferruginous, darker at apex; anterior femora piceous across the middle, strongly inreas- sated, with about three small teeth along the inner (anterior) edge, the apical the larger.
Described from nine examples from Victoria (presumably Vancouver Island) in the collection of the Museum of Com- parative Zoology, and five from Olympia, Washington, in the Cornell University Collection. The Victoria specimens, which were kindly sent me by Mr. Henshaw, bare the MSS. name Megalonotus angustatus Uhler, which I have adopted, using, however, the earlier generic name Rhyparochromus. The elytra sometimes become pale castaneous, but the con- spicuous M-shaped marking seems to be constant. I have seen only brachypterous examples. This is the second North American species of Rhyparochromus known to me. Of the other, Megalonotus sodalicius Uhler, I have seen two examples taken in California by Mr. J. C. Bradley and be- longing to the Cornell University Collection.
Plintliisus americanus n. sp.
Closely allied to the European lasiomerus, a little larger and paler. Head impunctate, polished, apex of the cheeks produced in a minute spine either side of the tylus. Antennae distinctly tomentose ; first joint surpassing the tylus by one-half its length, second about one and one-half times the length of the first ; third and fourth fusiform, each about the length of the first. Rostrum reaching nearly to the front line of the intermediate coxas, the first joint attaining the prosternum, the second slightly longer. Pronotum but little narrowed anteriorly, the sides feebly sinuated posteriorly ; anterior angles abruptly rounded behind the eyes; posterior lobe coarsely punctured, anterior smooth, polished, with a row of small punctures behind the anterior margin; hind edge feebly concave. Scutellum equilateral, a little raised above the elytra, closely punctured. Elytra polished, closely punctured, the punctures more obscure on the disk of the corium, those of the clavus larger and arranged in lines. Membrane short, attaining the middle

of the fifth tergal segment, rounded behind, without visable venation. Anterior femora strongly incrassated, armed with two short teeth placed interiorly toward the apex. Length 3| to 4 mm.
Coloi': Head and pronotum castaneous or piceous, the posterior lobe of the latter, the legs and the rostrum flavo-testaceous ; scutellum piceous or black. Elytra flavo-testaceous or somewhat castaneous, becoming darker on the disk of the corium ; membrane whitish. Beneath piceous varied with castaneous, the ventral segments edged with paler. Tergum piceous-black. Antennae pale at base, becoming piceous apically. Normally this insect seems to be clothed with long pale hairs which are easily rubbed off.
Described from one male and two females taken at Fran- conia, New Hampshire, by Mrs. Annie Trumbull Slosson, and one female taken at Belleville, Ont., by Mr. J. D. Evans.
Drynius erassus n. sp.
Closely allied to unus Say, but larger and darker. Bucculae more arcuated than in units, leaving a broader rostral groove which reaches quite to the base of the head. Antennae longer, the second joint pro- portionally longer than the third. Rostrum reaching to the posterior coxae; in unus scarcely attaining the intermediate. Pronotum broader anteriorly and more convex than in the allied species ; in the male the anterior lobe is scarcely if at all narrower than the posterior, the sharply carinate sides but feebly sinuated ; posterior lobe a little paler and more coarsely punctured than the anterior, with a distinct medial depression as in unus. Scutellum as in unus but subcarinate behind the impressed disk. Elytra closely but more obscurely punctured than in unus. Pectus deeply punctured, propleura armed with a rounded tooth between the anterior coxae which in the other species is small and acute ; metapleural flaps impunctate and polished. Venter sha- greened, scarcely punctured, with the minute fulvous pubescence much less conspicuous than in unus. Anterior femora much incrassated, armed with one stout tooth near the apex. Length 6-7 mm.
Colors darker and more obscure than in unus. Head, anterior lobe of the pronotum, pectus and scutellum black ; antennae, legs, posterior lobe of the pronotum, elytra and venter rufo-piceous, becoming darker on the clavus and disk of the corium. Membrane blackish-opaque, paler at base and marked with a pale spot at the tip of the corium. Rostrum and tarsi pale rufo-testaceous.
Described from three examples, one male taken by Wm, Beutenmuller in the valley of the Black Mountains, N. C, July 29th, 1906; a female from Camden, N. J., collected by S. T. Kemp, and a female taken on the summit of Mt. Washington, N. H., by Mrs. Annie Trumbull Slosson, This

is distinctly larger and darker than the species I identify as unus. The smaller and paler form agrees best with Say's description in having the antennae " honey yellow," the sides of the pronotum distinctly arcuated with the carinate edges a " little depressed and translucent," and the length "one fifth of an inch," none of which characters would apply to the larger and darker crassus. On the other hand the elytra of the smaller species are distinctly paler on their base, a character not mentioned by Say, but this is much less con- spicuous in some examples, and need not invalidate the determination.
Phytocoris bipunctatus n. sp.
Closely allied to antennalis and annulicornis ; smaller, proportiona- tely narrower and darker than the former, with the sternum and base of the femora pale sanguineous, and the elytra marked with a con- spicuous round white dot near the apex of the corium. Length 4 A- mm.
Head shorter than broad ; vertex, viewed from above, a little longer than the breadth between the eyes, distinctly sulcate, slightly narrowed anteriorly, sloping, and then abruptly deflexed at apex ; fusco-ferrugin- ous ; clypeus prominent, black, with a large white discal spot ; throat pale rufous. Rostrum attaining the base of the abdomen ; rufo-testace- ous, piceous at tip. Antennas surpassing the tip of the elytra; first joint a little shorter than the basal width of the pronotum, its thick- ness two-thirds the superior width of the eye, minutely pubescent, fusco-ferruginous, slightly varied with pale with a whitish annulus before the middle and another near the apex; second joint slender, black, bi- annulate with white, the basal annulus farther from the base of the joint than in antennalis ; third joint two-thirds the length of the second, pale brown with the broad base and an ill-defined annulus beyond the middle pallid ; fourth feeble, shorter than the first and darker than the third. Pronotum sub-campanulate ; sides feebly arcuated ; cal- lousities small and rounded, prominent ; color fuscous, becoming black posteriorly and ferruginous brown anteriorly ; hind edge white, quad- risinuate before. Scutellum fuscous-brown or almost black, with the apex whitish and sometimes with a pale spot on either side of the base of the posterior lobe Elytra fuscous or blackish, becoming paler along the middle of the corium posteriorly and sometimes on the clavus inwardly ; corium with a conspicuous round white discal spot toward the apex ; cuneus deep fuscous with two black marks on the margin next the membrane. Membrane fuliginous, the nervures darker, outer edge with a small pale mark at the apex of the cuneus and a fainter one a little beyond. Beneath fuscous, becoming paler on the pectus and disk of the venter. Sternum, coxa?, trochanters

and base of the femora pale rufous ; anterior and intermediate femora becoming piceous toward their apex ; hind femora obscure fuscous, irrorate with paler; anterior tibiae blackish, triannulate with white; intermediate and posterior brown, obscurely varied with pale; tarsi brown, broadly annulate with pale. Genital segment of the male with a stout curved tooth before the sinistral genital notch.
Described from numerous examples swept by me from the dry grass in the open pine forests of Florida south of San- ford, and identified as Phytocoris antennalis in my list of Florida Hemiptera. This species is very close to antennalis, and especially to annulicornis, but I believe it distinct. The white elytral spots and the color of the legs are distinctive and apparently persistent. The general color also is darker than in annulicornis, and the basal joint of the antennae is shorter than in antennalis.
Last July I took, a characteristic example of antennalis at Ipswich, Mass., which extends its range considerably to the north.
Dichrooscytus marmoratus n. sp.
Pale yellowish-green more or less washed with clear green, especially on the pronotum and clavus, sometimes, and in life perhaps always, clear green on the pronotum, scutellum and elytra; costa, at least narrowly, yellowish ; cuneus toward its apex and the veins of the mem- brane sanguineous ; membrane fuscous irrorate with pale, especially toward the base, and marked with two larger pale spots on the mar- gin beyond the tip of the cuneus ; apical nervure of the corium darker or even sanguineous. Surface polished, clothed with short blackish hairs on the pronotum and elytra, with a few longer black hairs near the anterior margin of the pronotum. Head yellow, polished, im- punctate ; in the female broader than the front of the pronotum, but much narrower than in suspectus ; base of the vertex very obscurely impressed either side. Antennae rufo-testaceous, first joint surpassing the apex of the head by nearly one-half its length ; second about four times the length of the first and about one-half its thickness, linear ; third slender, one-half the length of the second, darker at apex ; fourth still shorter and thinner but longer than the first, fuscous. Pronotum polished, impunctate ; sides straight ; collum linear, distinct ; callou- sities prominent. Beneath yellowish, the propleura tinged with green. Legs pale, the tibia? sometimes tinged or irrorated with rosy pink ; tibiae darker at apex ; tarsi brown, black at tip. Length 5 mm.

of Philadelphia, and kindly loaned me for study by Dr. Skinner. The males have the pronotum more narrowed anteriorly, the eyes more prominent, the vertex narrower and more depressed and the rostrum shorter, not surpassing the hind coxae. Of perhaps 150 specimens sent most were of some shade of yellowish-green, but a few were of a clear green with the sanguineous color confined to the margin of the cuneus and veins of the membrane. This species differs from Dichrooscytus by the narrower head, almost immarginate vertex, and longer basal joint of the antennas. It has, how- ever, the impunctate pronotum and general facies of this genus, and I believe it should stand here and not in Lygus. The irrorate membrane is conspicuous and distinctive.
Lopidea cimeata, n. sp.
Oblong-ovate, broader than media and its allies ; fuscous-brown with the narrow costa and the cuneus pale. Length 6 mm.
Head fuller and proportionately broader than in media, the vertex not so sunken ; face broader below, the margins distinctly rounded beyond the insertion of the antennae ; color pale flavo-testaceous, base of the vertex black, large disk of the front fuscous with a broad pale longitudinal vitta ; clypeus black, polished. Antennas black ; first joint as long as the width between the eyes ; second as long as the head and pronotum together ; third two-thirds the length of the second ; fourth hardly so long as the first. Rostrum attaining the posterior coxae or nearly so ; piceous, with the sides of the first joint paler. Pronotum fuscous, with the anterior margin and the sides narrowly pale ; broader and shorter than in media; the callousities very strongly elevated, almost tubercular, separated by a deep impression; anterior margin feebly concave, broadly depressed ; sides broadly reflexed, a little sinuated ; hind margin slightly concavely arcuated ; posterior lobe dull, transversely rugose with a feeble depression. Scutellum fuscous, moderately convex. Elytra a little shorter and broader than in media, fuscous-brown ; base, costa, and a short streak on the base of the cubital vein slenderly pale, the commissural nervure very narrowly so; cuneus pale, tinged with rufous within and tipped with black; membrane dark fuliginous. Beneath brown, more or less tinged with rufous along the sides. Legs brown ; coxse, trochanters, and some- times the base of the femora whitish ; propleura pale or suffused with rufous.

N. Y., on August 4, 1906, where they seemed to be feeding on plant lice. This species is a true Lopidea, although it is broader and darker than any other species yet de- scribed from this country. The pale streak on the cubital nervure, and the whitish or rosy cuneus readily distinguish this species.
Mr. Fordyce Grinnell, Jr., has taken an insect on the San Jacinto Mountains, California, at an altitude of 5000 feet, which probably belongs to this species. It is darker on the head, abdomen, and elytra, and the latter wants the pale streak on the cubital nervure and the black tip to the cuneus, and the scutellum is rufo-piceous.
Hadrouema festiva n. sp.
Form of picta but with the vertex swollen as in robusta. Color black, corium orange, with a large black spot on the inner angle. Length 3^ mm.
Head prominent, the vertex strongly convex, especially in the female ; front vertical, strongly impressed at the base of the very convex tylus. Rostrum reaching nearly to the base of the intermediate coxae. An- tennae about as in picta, first joint very short and stout, armed with a few stiff black hairs ; second over three times as long as the first, minutely pubescent ; third a little longer than the second and thinner; fourth still more slender and shorter than the first. Pronotum longer than in picta, strongly narrowed anteriorly; sides feebly sinuated ; hind margin slightly concave ; humeral angles prominent ; surface roughly shagreened ; collar very narrow but distinct.
Color blackish piceous, sericeous pubescent and quite strongly prui- nose, especially beneath ; pronotum, elytra, and legs with longer whit- ish hairs ; inner cheeks paler ; slender hind edge of the ventral seg- ments pale ; corium fulvous, fading to yellowish inwardly and marked on the inner angle by a large blackish spot which connects with the black of the clavus ; membrane smoky iridescent and paler at the margin and along the cuneus, the nervures blackish.
Described from numerous examples taken at Alamagordo, New Mexico, in late April and early May, belonging to the Museum of the Academy of Natural Sciences of Philadelphia. I can find no description agreeing at all with this insect. In many examples there is a greenish incrustation occupying the depressions on the base of the vertex and on the sides of the pronotum behind the callousities.
