This paper is the result of a sho/c study of the material in the collection of the Academy of Natural Sciences of Philadelphia, which is mostly neotropicv.], and includes some species that have been but little noted heretofoie. I have taken the liberty of rede- scribing those of which, to 'ny knowledge, only the brief original description exists, and hav^ therefore given many additional charac- ters of specific value. The male genitalia iiolds very good characters, and I have there- fore given a few fig'ires sliowing their variations. The ovipositor of the female, ment'oned in the following descriptions, unless otherwise designated, refer only to the first section, not to the retractile portion. Ostei- Sacken, in his " Diptera from the Philippine Islands" (Berl. Eut. Zeit., xxvi, p. 194, 1882), describes the chtietotaxy of the Micropezidse, which I will give for tliose species treated herein. Of the thorax there are two priescutellars, two supra-alars, — one of which may be called the postalar, — two notopleurals, two scutellars, with tiie following exceptions : Calobata nehulosa Lw. has another bristle before the prsescutellars ; C. annu/ata Fab. and the genus Micropeza have no praescutellars. The pleurae of the genera Calo- bata and Cardiacephala have no distinct bristles, but there are one or inore series of long hair-like bristles on the posterior portion of the hypopleurse. In the genus Micropeza, on the other hand, there is a strong sternopleural bristle, with several minute ones below it, TKANS. AM. ENT. SOC. XXXIV. (1) .TANUAKY, 1908. 2 AMERICAN DIPTERA. but uo hairs on the hypopleura. The chsetotaxy of the head varies and will be treated in the description of each species ; but there is a common absence of the ocellar bristles in all genera, and of the frontal bristles in the genus Micropeza ; but the inner and outer verticals are present in all genera. MICROPEZA Meigen. lUiger's Magazine, ii, 276, 1803. Head somewhat conical, projecting forwards beyond the eyes, and the occiput much swollen posteriorly; the front and cheeks nearly parallel ; antennae short, third joint rounded ; thorax narrow, elon- gate; abdomen slender; auxiliary vein wanting; discal and second basal cells united ; apical cell narrowed or closed apically.

HighroUs, New Mexico (Viereck and Rehn). This specimen agrees so well with the typical description that there seems to be no doubt about it being this species, but it shows a few char- acters that differ from the typical, and which, with son)e additional characters, I will note here: the brown side stripes of the posterior portion of the front, and the vertex, noted in the typical descrip- tion, are connected by other lines which divide that portion of the head into yellow areas. The main stripes run from tlie upper cor- ner of each eye over the vertex, passing just inside or including the outer verticals, tlien passing on down the occiput, where tliev unite with eacli other at the neck ; another pair leave the main pair about opposite the ocellar tubercle, includes tlie inner verticals, and unites E. T. CRESSOX, JR. 3 with each other in an irregular .^pot at the post- vertical.-? ; a third pair descend vertically from the main pair to the posterior orbits of the eyes. The principal differences between this and its variety ajH^t^tta are given below. :vlicro|»eza (^liircansi) aiiil>i$;na vnr. nov. (PI. I, fisrs. 1. 2). Male. — Yellow to whitish below, marked with black or brown as follows: a median frontal vitta from the black ocellar tubercle nearly to the base of an- teniife; vertex and upper part of occiput, also a brown spot on the occiput under the neck ; a spot in each antennal fovese ; second and base of third antennal joint and the bare arista; dorsum of thorax limited on each lateral margin by a yellow stripe running from the neck to base of wing, this yellow stripe encroaches on the dorsum anteriorly, constricting the black portion to about the width of the neck ; postalar callus yellowish. The scutellum brownish, with a darker median spot. The pleura with a brown stripe running from the neck to, and connecting with, the black metanotum ; a brown or l)lack stripe on the ventral part of the sternopleura running from flie fore to the middle coxte.

If, upon further study of those species not herein mentioned, these groups still hold their well-marked characters, they may be, with safety, considered ^ood genera. I have, in the following table — which treats only of those species under observation — made these groups the primary divisions. The difference in form of the geni- talia of % and ovipositor of 9 seems to be the most marked char- acter for their separation. These differences, as well as their specific variations, I have shown, when they exist, by a series of sketches. Those instances where only the clasps of the male are figured, the other parts are similar. Front narrow, more than twice as long as wide; the ocellar tubercle nearer the occiput than to the antennje ; thorax more or less well developed an- teriorly, the humeral calli distinct; the genitalia much developed; the clasps of male, usually situated beneath the third abdominal seg- ment, are membraneous and sessile, greatly enlarged, not filiform ; the ovipositor of female shorty and irregularly developed, truncate at apex, not extending forward beneath the abdomen 1. Front nearly as wide as long; the ocellar tubercle about midway or nearer the antennte than to the occiput; thorax much constricted anteriorly, the humeral calli indistinct; the genitalia not unusually enlarged; the clasps of male situated nearer the apex of abdomen on a more or less elongated pedicle or common base, somewhat filiform; ovipositor of female long, tapering to a more or less filiform apex, and extending forward beneath the abdomen 2. 1.

In the females the surface, which is finely alutaceous, is less dis- tinctly or not at all metallic. From the three preceding species it is distinct by its more parallel form and proportionally longer elytra. From cylindrica it is recog- nizable by the characters given in the table. Its distribution is distinctly northern. Specimens have been seen from Newfoundland, Hudson Bay, Ft.

Head as wide as the thorax at apex ; frontal grooves moderately deep, anteriorly not extending on to the epistoma ; antennse slender, scarcely as long as the head and thorax, rufous; palpi rufous. Prothorax subquadrate, less than one-half wider than long, as wide at base as apex, widest at middle, slightly emargiuate at apex, subtruncate at base; anteiior angles rounded, slightly prominent; apex impunctate; base punctate; transverse im- pressions nearly obsolete; median line fine, entire, or but slightly abbreviated in front; basal impressions deep, very distinctly bifoveate; sides arcuate nearly to base, sinuate immediately in front of the hind angles, which are rectangulai-. .slightly prominent and carinate. Elytra together scarcely wider than the thorax and less than twice as long as wide, convex, deeply striate; striiE entire, finely punctate to behind the middle, the scutellar stria long, the eighth with the row of ocellate punctures very widely interrupted at middle; intervals slightly convex. Body beneath piceous or rufopiceous; metasternal episterna, sides of metasternum and of the first two ventral segments sparsely punctured. Legs rufous or rufopiceous; iuner margin of the middle and posterior femora with two setigerous punctures; posterior tarsi with the three basal joints slightly grooved on the outer side. Length .37-. 44 inch ; 9.25-1] mm. In the males the upper tooth of the middle tibiae is distinctly below the middle and prominent; the lower tooth is small and situ- ated al)out half way between it and the apex. The fenudes have the surface finely alutaceous. Its form is more convex than that of rufimaitd, with the elvtra at most scarcely flattened on the disk. The carina at the hind angles of the thorax is less acute than in rnjhnana. The three basal joints of the hind tarsi are grooved on the outer side as in esch- scholtzi and melanogastrica, and by this character, as well as bv its form and the less acutely carinate hind angles of the thorax, it seems to lead towards these last named species.

Head srareely narrower than the thorax at apex ; frontal grooves short, not extending ffirward on to the epistoma ; antennae slender, nearly as long as the head and thorax, rufo- testaceous; palpi rufotestaeeons. Prothorax subquadrate, about one-half wider than long, as wide at base as apex, with a few scattered punctures each side at apex, distinctly punctate at base; apex slightly emarginate; sides arcuate, dis- tinctly but not strongly sinuate in front of base, which is nearly truncate; ante- rior transverse impression distinct, the posterior nearly obsolete; median line abbreviated in front; basal impressions deep, punctate, very distinctly bifoveate, the inner fovea longer tlian the outer; liiud angles rectangular, obtusely cari- nate.

Length .3.3-. 35 inch ; 8.25-8.75 mm. In the males the teeth of the middle tibise are much nearer the apex than usual, the upper being situated about two-thirds from the base, the lower about midway between it and the apex. The form somewhat recalls that of rtifanana, but the hind angles of the thorax are obtusely carinate, the posterior tarsi grooved ex- ternally and the size smaller, while the position of the teeth of the middle tibite is also different.

Length .3S-.42 inch ; 9.5-10.5 mm. The males have the middle tibiae normally dentate. This species approaches melanogastrica very closely, and, indeed, seems doubtfully distinct. The chief points of difference are attbi-ded by the prothorax, which is slightly less distinctly emarginate at apex in the present species, with the side margin narrower and not translucent and the fovese of the basal impressions slightly oblique. The antennae differ slightly in color, while the elytra are usually paler iji melanogastrica than in eschschoUzi. It occurs in Alaska and Kamchatka. 14.

Prothorax subquadrate, about one-half wider than long, as wide at ba-se as apex, punctate at base and more sparsely so at apex; apex emarginate, the anterior angles rounded ; transverse impressions nearly obsolete; median line fine, abbreviated in front; basal impressions broad, deep, bifoveate, the foveiE perpendicular to the base, the inner longer than the outer; base trun- cate ; sides with the margin narrowly reflexed but distinctly translucent, rounded, slightly sinuate in front of the hind angles, which are rectangular, slightly prominent and obtusely carinate. Elytra together slightly wider than the thorax and less than twice as long as wide, subparallel, deeply striate ; humeri rounded ; striae distinctly punctate, obsoletely so at apex ; intei'vals nearly flat ; inflexed portion of the elytra somewhat paler. Body beneath nearly black; meso- and metasternal episterna and sides of metasternum and of the first two ventral segments punctate.

The elytra are usuall}- brownish in color, although in a few specimens seen they are not paler than in the last named species. The antennae are rufous, and ihe legs usually so, though sometimes piceorufous. Like eschaclioltzl, it occurs in Alaska and Kamchatka. 15. A. bruiiiiipenniN Dej. — Form nearly oblong, elongate, convex. Color black, at most scarcely teneous, the elytra often piceons or brown ; surface shining in the males, finely alutaceous in the females.

Prothorax about one-half wider than long, as wide at base as apex, impunctate or rarely with a few scattered punctures at apex, more or less sparsely punctured at base, usually more or less transversely wrinkled along the median line; apex emarginate, the anterior angles rounded ; transverse impressions moderate or feeble; median line fine, entire or abbreviated for a short distance in front: basal impressions broad, deep, more or less coarsely punctate, bifoveate, the inner fovea longer than the outer; base truncate; sides with the margin narrowly re- flexed, arcuate from apex to base or sometimes oblique for a short distance in front of the hind angles, which are obtuse and obtusely carinate. Elytra together scarcely wider than the thorax and less than twice as long as wide, striate; strise entire, punctate to behind the middle, the scutellar stria moderate, the eighth with the row of ocellate punctures widely interrupted at middle; intervals rather broad, flat or nearly so ; humeri rounded. Body beneath black ; meso- and metasternal episterna, sides of metasternum and of the first two ven- tral segments impunctate t>r at most sparsely punctate. Legs varying in color from black to nearly rufous, usually piceous or rufopiceous; inner margin of the middle and hind femora with two setigerous punctures; posterior tarsi with the three basal joints not or at most veiy feebly grooved on the outer side. Length 33-.45 inch ; 8.25-11.25 mm. In the males the middle tibije are normally dentate. This specie.s, as above defined, includes what have been known heretofore in collections in this country, at least, as A. hrminipennis Dej. and .4. h tjparhorea Dej. The former name has been i-etained, as 1 regard it as more than probable that the species known as hi/perborea in American collections is not the hfjperborea of Dejean, The original description does not apply to the present si)ecies, while Dejean's remark.s, as well as those of Putzeys, who had the type before him, seem to refer to a different species. As might be expected from its wide geographical range, consider- tible variation is exhibited, and several forms might be selected, which, if studied from uniques or from a very small series of speci- mens, would doubtless be regarded as distinct .species. These, how- TEANS. AM. ENT. SOC. XXXIV. FEBRUARY, 1908. 32 AMERICAN COLEOPTKRA. ever, intergrade in the large series before me. One of the more important variations is to be seen in the prothorax, the sides of wliich are in some examples arcuate from apex to base, the hind angles being very obtuse or almost rounded, while in others the sides are arcuate to behind the middle, from thence oblique to the hind angles, or, in one or two specimens, with a very feeble trace of sinu- ation immediately in front of them, the angles being obtuse and not prominent. The elytral strire vary in depth as well as in the coarse- ness of their punctation, while the intervals vary from flat to feebly convex. The color varies from uniformly black to bicolored, the head and thorax being black and the elytra more or less brownish, sometimes uniformly reddish-brown, sometimes with the sutural and lateral margins dark, and sometimes piceous, only slightly paler than the head and thorax. Much the same range of variation may be observed in the color of the legs, as stated in the description, while the hind tarsi vary from very feebly to not at all grooved on the outer side. These variations are so intermingled that it has been found impossible to separate even varieties by characters of any constancy. The species is most closely related to e-schscholtzl and melanogas- trica, but is readily distinguishable from both by the obtuse hind angles of the thorax. Nearly three hundred examples have been studied. It occurs in Labrador, on Mt. Katahdiu, Maine, Mt. Washing- ton, New Hampshire, Mt. Mansfield, Vermont, in the Hudson Bay region, at high altitudes in the Rocky Mountains of Colorado, in Alaska, extending northward to Point Barrow, and on St. George's Island and St. Paul's Island in Behring Sea. 16.

Legs rufopiceous; middle and posterior femora with two setigerous punctures along the inner margin ; the two basal joints of the hind tarsi grooved on the outer side. Length .44 inch ; 11 mm. The above is from LeConte's type, which was received from Motschulsky under tlie name "■ rujiviaiius." It resembles most nearly eschscholtzi, but is abundantly distinct by the characters given above. Under his description LeConte gives the locality as "Russian America," but there is no locality label attached to the specimen ill question. 17.

Elytra oblong-oval, elongate, together distinctly wider than the thorax, striate; strias entire, finely punctate to behind the middle, the scutellar stria shorter than usual, the eighth with the row of ocellate punctures broadly interrupted at middle ; intervals flat. Body beneath of the same color as above ; meso- and metasternal episterna and sides of metasternum sparsely and sides of first two ventral segments more densely punctured. Legs varying frou) rufous to piceous; middle and hind femora with two setigerous punctures along the inner margin; basal joint of middle and hind tarsi feebly grooved externallv. Length .44-. 46 inch ; 11-11.5 mm. In the males the middle tibite are distinctly bidentate, the teeth being normally placed. A very distinct species, (littering markedly from our other Cyrtonoti in form, and bearing considerable resemblance to the Siberian ^4. fodina'. It is readily re(H)gnizable l)v the characters given. It seems to me by no means improbable that this mav be Inmer- borea Dej., but it would be necessary to see Dejean's type before treating it as such.

Color piceous or nearly black, shining, the inflexed portion of the elytra usually paler. Head slightly narrower than the thorax at apex ; frontal grooves short, deep, not extending on to the episterna; antennse slender, shorter than the bead and thorax, rufous; palpi rufous. Prothorax subqnadrate, less than one-balf wider than long, distinctly wider at base than apex, widest slightly in front of middle, impunctate at apex, punctate at base; apex emarginate, the anterior angles rounded, slightly prominent ; transverse impressions feeble ; median line distinct, slightly abbreviated in front; basal impressions broad, deep, bifoveate, the fovese coarsely punctured and more or less confluent; base truncate; sides with the margin narrowly retlexed, arcuate, sinuate in front of the hind angles, which are rectangular and carinate. Elytra together scarcely wider than the thorax and more than one-half longer than wide, deeply striate; humeri suban- gulate ; striae deeply punctate, more finely toward the apex, the scutellar stria moderately long, the eighth with the row of ocellate punctures widely interrup- ted at middle; intervals slightly convex. Body beneath piceous or rufopiceous ; meso- and metasternal episterna, sides of metasternum and of the first two ven- tral segments coarsely punctate. Legs rufous; inner margin of middle and hind femora with two setigerous punctures ; tai'si without external grooves. Length .40-. 47 inch ; 10-11.75 mm. The middle tibioe are normally dentate in the males. The name fulvipes assigned to this species by Putzeys being pre- occupied (Serville, Fauna France, 1821), that of pennsylvanica is proposed in its pkice. One of our most easih' recognizable species, differing from all the others in our fauna, except elongata, by the prothorax verv distinctly wider at l)ase than apex, while from the last named it is readily distinguishable by numerous characters mentioned above. Its distribution is interesting. It is the only species of the sub- genus occurring in the more eastern United States south of the Lake Superior region, except at high altitudes. Specimens are known to me from New Jersey, Pennsylvania, District of Cohunbia, Ohio, Illinois, Tennessee, Alabama, Missouri, Nebraska, Kansas, Iowa, Wyoming, Texas and New Mexico, and also from Ontario, Canada. It was apparently taken in great numbers near Alle- ghanv, Pa., by the late Dr. Hamilton. ROLAND IIAYWARD. 35 19. A. liscinatopa Dej.— Elongate, iDoderately convex. Head and thorax black, in the males inore or less aeneous, the elytra in that sex green or cupreous with strong metallic lustre, in the females usually very feebly metallic or nearly black; surface shining. Head as wide as the thorax at apex; frontal grooves long, deep, extending forward on to the cpistoma ; antenna shorter than tlie head and thorax, thickened, piceous or rufo))iceous; palpi rufous or rufopiceous. Prothorax about one-half wider than long, subquadrate, widest slightly in front of the middle, as wide at base as apex, impunctate at apex, often more or less transversely wrinkled along the median line; apex feebly eniarginate; trans- verse impressions moderate or sometimes feebly impressed ; median line distinct, abbreviated in front; basal impressions broad, deep, rather finely and sparsely, sometimes ol)soletely punctate, distinctly bifoveate ; sides arcuate from apex to base, the margin distinctly reflexed, slightly more widely toward the base; base truncate; hind angles obtuse, not prominent, cariiiate. p]lytra together slightly wider than the thorax and more tljan one-half longer than wide, subparallel, slightly flattened on the disk, moderately deeply striate; humeri rounded ; strife entire, usually obsoletely punctate, rarely distinctly so, the scutellar stria mod- erate, the eighth with the row of ocellate punctures broadly interrupted at mid- dle; intervals slightly convex. Body beneath black or dark piceous, rarely feebly feneous in very highly colored specimens, impunctate, except the meso- sternal episterna which are finely and sparsely punctured. Legs varying from rufous to rufopiceous; middle and hind femora with two setigerous punctures along the inner margin ; basal joint of the hind tarsi slightly grooved externally. Length .40-.52 inch ; 10-13 mm. In the males tlie middle tibite are only feebly bisiiiuate on the inner side near the apex. The females are larger, more robust and less shining than tlie males, and with at most l)ut feeble metallic lustre. The name Jurmatopa Dej. has priority over that of simili'i Kirbv, by which the species has been generally known. Readily distinguishable from all the other North American spe- cies of the subgenus known to me by three structural characters of importance, i. e., the extension forward of the frontal grooves on to the epistoma, the thickened antennae, and the middle tibiae of the males feebly bisinuate within near the apex. The middle tibiae are not dentate in that sex, and it is often difficult to distinguish the feel)le bisinuation, which is apparently the homologue of the teeth occurring in our other species. In color and facies it differs al.-^o from our other Cyrtonoti. It is, in many respects, a very aberrant species, and seems to lead toward Bradytus ; but the posterior tibia' of the males show no trace of the pul)escence characteristic of that subgenus, and the prosternum is not margined at tip. On the whole it seems best placed at the end of the present subgenus. TRANS. AM. ENT. SOC. XXXIV. ' FEBRUARY. 1908. 36 AMERICAN COLEOPTERA. In distribution it is essentially northern.

Prothorax distinctly wider in front of base. Prosternum not margined at tip. Apical spur of anterior tibiae simple. Middle tibiae not dentate on the inner side in the males. Posterior tibiae not pubescent on the inner side in the males. Intermediate in characters between Cyrtonoins and Leioenemis, differing from the former by the middle tibire simple in both sexes, and from the latter by the prosternum not margined at tip. But one species occurs in our fauna, which was formerly referred with avlda to Leioenemis. 20. A. areiiaria Lee. — Nearly oblong, convex, the elytra flattened on the disk. Golor piceous, shining. Head as wide as the thorax at apex ; eyes very finely granulate; frontal grooves small, punctiform ; antennte rufous, as long as the head and thorax ; palpi rufous, the terminal joint slightly swollen, acumi- nate toward the tip. Prothorax about one-half wider than long, wider at base than apex, impnnctate; apex emarginate ; transverse impressions distinct ; me- dian line distinct, abbreviated before and behind ; basal impressions linear, the inner fovea distinct, the outer obsolete; base truncate, slightly obliquely so each side; sides with the margin narrowly reflexed, rounded, oblique behind; hind angles slightly obtuse and not carinate. Elytra wider than the thorax, finely striate; striae entire, impnnctate, the scutellar stria obsolete, the eighth with the row of ocellate punctures narrowly interrupted at middle; humeri subangulate; intervals slightly convex. Body beneath piceous, impnnctate. Legs rufous; all the femora with two setigerous punctures along the inner margin; tarsi not grooved on the outer side. Length .20-. 23 inch ; 5-5.75 mm. The anterior tarsi are more narrowly dilated than in most Amarse. The males have one, the females two anal setae. A very distinct little species, easily recognizable from the others in our fauna. It seems subject to but slight variation. In a few specimens examined a faint trace of the scutellar stria has been observed, usually, however, on but one elytron. The form of the palpi is dirterent from that of any of our otiier species of the genus, and resembles, judging from descriptions, that of the European A. (Leirouotus) glabrata. It is apparently northern in its distribution. Specimens have ROLAND HAYWARD. 37 been seen from Canada, Maine, the White Mountains of New Hamp- shire, Tyngsboro, Lowell and Boston, Massachusetts, INIichigan and Lake Superior. Subgenus LEIOC^V'E.TIIS Zimm. Prothorax wider in front of base. Prosternurn margined at tip. Apical spur of anterior tibifie simple. Males with the middle tibiae not dentate on the inner side. Posterior tibiic not pul)escent on the inner side in the males. This subgenus seems to lead from Cyrtonotus and Leironotvs toward Bradytus. In our species the prosternum, although mar- gined at tip, is less distinctly so than in Bradytus, Tria;nYTUS Zimni. Prothorax wider in front of base. Prosternum margined at tip. Anterior tibiie with the apical spur simple. Males with the middle tibise not dentate on the inner side. Posterior tibiae distinctly, usually densely pubescent on the inner side in the males. ' Distinct from all the subgenera, except Amara s. s. and Trkenn, by the posterior tibise distinctly pubescent on the inner side in the males, while from the two latter it is at once distinguishable by the form of the prothorax. From Cyrtonotus and Leironotus it differs in having the prosternum margined at tip, while it resembles them in having the thorax distinctly wider in front of base. With all but Cyrtonotus it agrees in having the middle tibise not dentate within in the males, and with all except TrUetia by the apical spur of the anterior tibite not trifid. The inales of all our species in which that sex is known to me, in addition to the secondary character above mentioned, have the anterior tarsi dilated and one anal seta each side, two being present in the females. A secondary sexual character of some importance in classification is also to be observed on the prosternum of several species. This consists of an impression varying from a deep fovea to a shallow punctured area or groove. In at least one species it is entirely wanting. Our species agree in having all the femora normally bisetose along the inner margin. They may thus be separated : Scutellar stria long 2. Scutellar stria very sliort or obsolete ; form convex ; nietasternal epistenia punc- tured ; males with a shallow oval space, with a few small punctures at middle of prosternum. Length .30-.40 inch 22. exarata Dej. 2. Prosternal side pieces impunctate 3. Prosternal side pieces punctate; nietasternal episterna jiunctured. Viridi, or cupreo-teneous ; prothorax nearly twice as wide as long, punctate at base, sides and apex, distinctly emarginate at ajiex ; basal impres- sions feebly bifoveate; prosternum simj)le in both sexes.

Length .28-. 32. 26. schwarzi Nobis {septentiowiUn [I Lee). Prosternum with shallow, sparsely punctured oval space at middle in the males, simple in the females. Length .35-. 43 inch. 27. latior Kirby. 22. A. exarata Say. — Oblong-oval, robust, very convex. Color varying from piceous to black, shining. Head slightly narrower tlian the thorax at apex ; frontal grooves short, triangular, not extending forwaid on to the episterna; eyes moderate, finely granulate ; anteuuse as long as the head and thorax, rufous ; palpi rufous. Prothorax suhquadrate, about one-half wider than long, broadest about the middle, wider at base than a])ex ; apex emarginate, the anterior angles rounded ; base feebly bisinuate; median line distinct, abbreviated in front; ante- rior transverse impression varying from moderately distinct to nearly obsolete, the posterior obsolete or feebly marked at middle; basal impressions broad, coarsely and usually densely punctate, very distinctly bifoveate; sides with the margin narrowly but distinctly reflexed, arcuate, sinuate for a very sliort dist- ance in fiont of the hind angles, which are small, acute, slightly prominent and very obtusely carinate. Elytra slightly wider than the thorax, subparallel. deeply striate; strife deeply and closely punctate, less distinctly toward the apex ; scutellar stria usually very short or obsolete or represented by punctures, rarely distinct, though shorter than in our other species of the subgenus; inter- vals convex. Body beneath piceous or rufopiceous, the abdomen usually slightly paler; prosternum with the sides rather sparsely punctured in front, the side- pieces usually impunctate, rarely with a few scattered punctures; meso- and metasternal episterna, sides of raetasternum and of ventral segments coarsely ])unctate. Legs varying from rufous to rufopiceous. Length .30-. 40 inch : 7.5-10 mm. The males have on tlie pro.stenuim at middle a small, nearly oval space with a few small pimctiires. The posterior tibiiP are less densely pubescent on the inner side in that sex than is usual in this subgenus, and the pubescence extends but for a short distance from the apex of the tibia. Superficially this species resembles most closely A. {Leiocnemis) avi.da Say, but in addition to the subgeneric characters it differs by several others mentioned above. It also resembles A. fxdva DeGeer of Europe. From our other species of Bradytus it is distinguishable by the characters given in the table. TKANS. AM. ENT. SOC. XXXIV. FEBRUARY, 1908. 40 AMERICAN COLEOPTERA. Immature examples are often pale yellow, and it was doubtless upon one of these that A. furtiva Say was based. The variation shown in the punctuation of the prosternal side pieces as well as in the prominence of the scutellar stria shows that great care should be used in basing species solely upon these characters. It is known to me from Massachusetts, New York, New Jersey, Pennsylvania, District of Columbia, West Virginia, North Carolina, Ohio and Nebraska. 23. A. glaciali»$ Manu. — Form oblong-ovate, moderately convex. Color viridi-aineous or cupreo-feueous, shining. Head as wide as tlie thorax at apex; eyes large, prominent; frontal grooves short, not extending forward on to the epistoma ; antennae less than one-half the length of the body, {)iceous, the first joint more or less rufous; palpi piceous. Protborax subquadrate, nearly twice as wide as long, widest slightly in front of the middle, slightly wider at base than apex; apex emarginate, the anterior angles rounded but prominent; median line distinct, entire or slightly abbreviated in front; transverse impiessions obsolete; basal impressions shallow, feebly, sometimes obsoletely, bifoveate; surface punc- tate at base, sides and apex, the disk impunctate ; base slightly bisinuate behind ; hind angles subacute and slightly prominent, not carinate. Elytra distinctly wider than the thorax, striate, flattened on the disk ; striae entire, dis- tinctly punctate, the punctures becoming obsolete toward the tij); scutellar stria long; intervals flat. Body beneath black; prosternum with the side-pieces punctate; meso- and nietasternal episterna, sides of metasternum and of first two ventral segments coarsely punctured. Legs rufous, the tibiae externally and the tarsi more or less piceous; middle and hind tarsi with the two basal joints grooved on the outer side. Length .25-. 32 inch ; 6.25-8 ram. The males have no trace of punctured fovea or groove on the prosternum at middle. In the females the elytra are finely aluta- ceous. Originally placed in Bradytua by Mannerheim, it was removed to Cyrtonotus by Putzeys, where it has since been allowed to remain, although its facies is eminently that of the former subgenus, females only having been known until recently in this country. Putzeys in describing the only specimen (a male) in the Chaudoir collection, refers to the lower tooth of the middle tibia as being more promi- nent than the upper, and says that the hind tibiie are glabrous on the inner side. In studying some half dozen or more males in the collection of the National Museum, I have been unable to detect any trace of teeth on the middle tibia;, while in .several specimens, carefully cleaned, a sparse, fine pubescence is plainly discernable on those of the posterior legs. Furthermore, the prosternum is very distinctly margined at the tip, a character entirely unknown in ROLAND HAYWARD. 41 Ci/rtonotvs. I have, therefore, no hesitation in restoring it to Bradijtus. But slight variation has been observed. This is mainly in the coarseness of the punctuation of the thorax and in the color of the legs, some individuals having thera almost entirely rufous, while in others the tibiag on the outer side and the tarsi are piceous. This variation is indicated by Mannerheim as: "Var. b. Cuprea, pedibus rufis, tibiis posticis basis tarsisque omnibus infuscatis." The type is from Kenai, " Var. b" from Kamchatka, and I have seen specimens from Kenai (LeConte collection), from Ungava Bay, Hudson Bay territory and from Labrador. 24. A. piitzeysi Horn. So closely allied to apricaria Payk. as to require no special de- scription. In fact, it has been suggested as not improbably a syno- nym of that species. From the latter, however, it is .separable by the coarsely punctured prosterual side pieces. The prothorax is only very feebly emarginate at apex. By the first character it approaches glacialis Mann. But one specimen, Dr. Horn's type, is known to me. It meas- ures .32 inch (8 mm.) in length, is a female and is in the LeConte collection. Beneath his description Horn states it to be a male, but this is without doubt a typographical error. The example referred to not only bears the label "type," but agrees with the description and bears all labels indicating its authenticity, while additional evidence is afforded by the fact that Dr. Horn refers to no secondary male characters, these being mentioned in the same paper in con- nection with our other species and being of systematic importance in the subgenus Bradytus. It was received by Dr. LeConte from Putzeys as coming from St. Pierre Miquelon, Newfoundland. 25. A. apricaria Pn.yk. — Form moderately elongate, oblong-oval, convex, the elytra slightly flattened on the disk. Color dark nigro-piceoiis or nearly black, sometimes very faintly reneous, shining, the surface very slightly aluta- ceous in the females. Head scarcely narrower than the thorax at apex ; frontal grooves short, not extending forward on to the epistonia; eyes large, finely granulate; antennge rufous, slightly shorter than the bead and thorax; palpi rufous. Prothorax subquadrate, rather more than one-half wider than long, broadest about the middle, wider at base than apex, coarsely punctate at base and usually with a few punctures near the apical margin, the surface more or TE.\NS.

' less transversely wrinkled alonj: the median line; apex emarginate; median line distinct, abbreviated in front; transverse impressions varying from moderately vcell marked to nearly obsolete; basal impressiojis broad, deeply bifoveate; base truncate; sides with the margin narrowly reflexed, rounded, sinuate immedi- ately in front of the hind angles, which, though small, are acute, slightly promi- nent and obtusely carinate. Elytra slightly wider than the thorax, deeply striate; strite entire, very distinctly and closely punctate, the punctures becom- ing evanescent at tip; scntellar stria long; intervals flat or nearly so. Body beneath piceous; prosternum more or less punctured at the sides in front, the prosterual side-pieces impunctate; meso- and metasternal episterna and sides of metasterjiurn and first three ventral segments closely punctate. Legs rufous. Length .24-.33 inch ; 6-8.25 mm. In the males there is a deep oval fovea on the prosternum slightly in front of the middle, while between tins and the tip is a short groove,, the latter being present also in the females, though less marked than in the males. But slight variation, besides what is indicated in the description, is shown. A few specimens in the series before me are devoid of punctures near the apex of the thorax. The two basal joints of the middle and hind tarsi sometimes exhibit faint traces of grooves. About fifty specimens have been studied. It is known to me from the Magdalen Islands, Nova Scotia, Canada, the White Mountains of New Hampshire (occurring at as high an altitude, as 5053 feet, as the Lake of the Clouds on Mt. Washington), Mt. Desert, Maine, Lowell, Tyngsboro, Manches- ter, Methuen, Brookline, Nantucket and Chicopee, Massachusetts, the Adirondack Mountains, New York, and Newark, New Jersey. It occurs also in Europe and Siberia. To the kindness of Herr Th. Gotzelmann I am indebted for examples from Ujj)est, Hungary. 26. A. schwarsei Nobis. — Form oblong-oval, moderately convex, the elytra slightly flattened on the disk. Color dark piceous or nearly black, with faint feneous lustre, shining, very finely ftlutaceous in the females. Head scarcely narrower than the thorax at apex ; eyes moderately large and prominent; frontal grooves short, not extending forward on to the epistonia; autennaj slightly shorter than the head and thoiax, rufous; palpi rufous. Prothorax subquadrate, about one-half broader than long, widest about the middle, slightly wider at base than apex ; apex emargiiiate; median line distinct, slightly abbreviated in front; transverse impressions feeble, the posterior usually obsolete; basal impres- sions broad, deeply bifoveate, punctate; base truncate; sides with the maigin narrowly reflexed, but translucent, slightly rounded in front, oblique beliind ; angles obtuse, obtusely carinate. Elytra slightly wider than the thorax, striate; strise entire, punctate to behind the middle, tlie scutellar stria long; intervals nearly flat.

Legs dark rufous. Length .28-.32 inch ; 7-8 mm. The above name is propo.^ed in place of septentrionalis Lee. (1 with the apical spur stouter than usual ; tarsi n((t grooved on the outer side. Length .29-.36 inch ; 7.25-9 mm. In the males the hind tibise, although distinctly pubescent, are somewhat less conspicuously so than is usual in the subgenus. From allied species it seems distinct by the characters given in the table. The position of the posterior marginal setigerous punc- ture is nearly as in cupreolata, while the tip of the prosternum recalls that of conflata. It occurs from Massachusetts southward to South Carolina and Alabama and westward to Lake Superior, but appears to be local. 4L A. parviceps n. sp. — Form nearly oblong, very convex. Color black, .shining. Head small, slightly narrower tlian the thorax at apex, and scarcely one-half as wide as the thorax at base; frontal grooves obsolete ; antennae not carinate. with the three basal joints testaceous, the next four rufopiceous (the others lacking in the type); palpi testaceous. Prothorax very convex, about one-half wider than long, narrowed from ba.se to apex; very strongly narrowed from base to apex, very strongly narrowed in front of middle; apex deeply emarginate, the anterior angles prominent, rounded ; transverse and basal im- pressions obsolete; median line fine, abbreviated in ficint; sides with the margin narrowly reflexed, arcuate, the posterior lateral setigerous punctures large, distant from the side margin ; base nearly truncate; hind angles rectangular, not carinate.

Length .32 inch ; 8 mm. Ajiproaches most nearly A. cupreolata, from which it seems iibundaiitly di.stinct by tlie form of the thorax, smaller head and color of tlie legs. The posterior lateral setigerous puncture of the thorax is even more distant from the side margin than in that species. Only one specimen, a male, is known to me. It is from Lake Superior, and is in the LeConte collection at Cambridge. 42. A. cupreolala Putz. — Oval, convex. Cupreo-seneous or more rarely nigro-ffiiieous, shining, the females very finely alutaceous. Head slightly nar- rower than the thorax at apex ; antennae shorter than the head and thorax, not carinate, piceous, the three basal joints paler; palpi rnfopiceons. Prothorax sub- quadrate, about oue-half wider than long, wider at base than apex, impunctate or rarely ohsoletely punctured at base; apex deeply emarginate, the anterior angles rounded but prominent; sides narrowed from about one-thiid in front of base and rounded to apex, margin nariowly reflexed, the posterior setigerous puncture distant from the side margin and distinctly nearer the basal ; transverse impressions obsolete; median line fine, abbreviated in front; basal impressions feeble and poorly defined ; base nearly truncate ; hind angles obtuse, rounded, not carinate. Elytra not wider than the thorax, subparallel to behind the mid- dle, striate; strise impunctate or rarely ohsoletely punctate, entire, the scutellar stria not terminating in an oceliate puncture at base, the eighth with the row of oceliate puiictures rather narrowly interrupted at middle; intervals flat or nearly so. Body beneath black, impunctate; prosternum broadly rounded at tip. Legs piceo-rufous, the femora usually darker; all the femora with two setigerous punctures along the inner margin; basal joints of middle and hind tarsi not grooved. Length .26-. 33 inch ; 6.5-8.25 mm. The posterior tibiae of the males are moderately densely pubescent on the inner side. Superficially this species resembles most clo.^ely mjmncticollis, but is at once recognizable from it by the absence of the oceliate punc- ture at the base of the scutellar stria. From conflatu it is readily distinguishable by the obtuse hind angles of the thorax, the position of the posterior lateral seta, as well as by its less robust form and the color of the legs. Examples have been seen in which the base of the thorax and elytral strife are sparsely, ohsoletely punctate, but they are connected by intergrades with the typical form. It is known to me from Canada, New Hampshire, Ma.ssachusetts, New York, New Jersey, Pennsylvania, Illinois, Kentucky, Utah, Nebraska, Kansas and Colorado. TR.\NS. AM. ENT. SOC;. XXXIV.

Body beneath black, impunctate; prosternum subtruncate or very broadly rounded at ti]i. Legs black; all the femora with two setigerous punctures along the inner margin ; middle and pos- terior tarsi with the basal joint at most very feebly grooved on the outer side. Length .35-.42 inch ; 8.75-10.5 mm. Easily known from A. cupreolata by its larger size and less con- vex form, as well as by tlie position of the posterior puncture of the side margin of the thorax and the color of the legs. It occurs along the Pacific Coast from California to British Columbia, and I have seen one specimen from Utah. 44. A. brunnipes Motsch. — Form elongate, convex. Nigro-a>neous, very finely alutaceous. Head scarcely narrower than the thorax at apex; antenna" shorter than the head and thorax, not carinate, piceous, the first three joints paler; palpi dark rufous.

Elytra very slightly wider than the thorax, striate; striae im- punctate, entire, the scutellar stria without ocellate puncture at base, the eighth with the row of ocellate punctures very broadly interrupted at middle; intervals flat. Body beneath dark piceous, impunctate. Front and middle legs daik rufous (the hind pair wanting in the specimen studied) ; middle femora with two setigerous punctures along the inner margin; terminal spur of anterior tibise somewhat stouter than usual.

The anal segment is bisetose each side. 45. A. pi'olcnNa. Putz. — Oblong-oval, moderately convex. Black sometimes tinged with blue or rarely slightly aeneous, usually dull, the surface alutaceous, more strongly so in the females, at most feebly shining in the males. Head slightly narrower than the thorax at apex ; antennae shorter than the head and thorax, black, the two basal joints rufous, the second usually somewhat darker, joints 2-3 strongly carinate; palpi black.

Elytra slightly wider than the thorax, finely striate, the sides subparallel to behind the middle; liunieri slightly prominent; striae entire, impunctate, the scutellar stiia not terniinatiiig in an ocellate puncture at base; the eighth with the row of ocellate punctures narrowly interrupted at middle; intervals fiat or nearly so. Body benealli black, impunctate ; presternum rounded at tip. Legs black; anterior and hind femora with two. the middle with four setigerous j)unctures along the inner margin ; middle and hind tarsi with the basal joint not grooved on the ontei- side. Length .30-. 36 inch ; 7.5-9 mm. Very closely allied to confusa, from which it is not easily recog- nizable except by comparison. The forn) is more oblong and less convex, and the color duller and less aeneous. The hind angles of the thorax are slightly rounded at tip, and the humeri of the elytra more prominent. The posterior setigerous puncture at the side of the thorax is nearer the basal than the lateral margin. It is apparently northern in its distribution. Specimens have l)een seen from the Hudson Bay region, Alberta, M(uitana, Wyom- ing and the mountains of Colorado. It was described by Putzeys from the shores of the Rupert River, Hudson Bay Territory. 46. A. confuMa Lee— Characters nearly as in protenm I'utz. Form less oblong, broadly oval, more '•onv'jx. Color seneous or nigro-aeneous, the surface shitiing. Prothorax slightly less deeply eniarginate at apex; posterior lateral Setigerous puncture equidistant from side and basal margins; hind angles rec- tangular. Elytral humeri somewhat less prominent. Middle and hind tarsi with the basal joint at most finely grooved externally. Length .3:2-. 35 inch ; 8- 8.75 mm. As will be seen by the above brief resume of the points of diiier- ence between this and the preceding species, the two are difficult of separation, those most worthy of note being the more oval and more convex form of confusa, with its more shining surface, and the different position of the posterior puncture of the side margin of the prothorax. The antennse are of the same color as in protensa, with the second and third joints strongly carinate above. The arrange- ment and number of the setigerous punctures along the inner m:ii-- gin of the femora is also alike in the two species. TRANS. AM. ENT. SOC. XXXIV.

Head slightly narrower tlian the thorax at apex; antennae shorter tlian the head and thorax, black, the two basal joints paler, joints 2-3 strongly carinate; palpi piceous. Prothorax nearly twice as wide as long, snliquadrate, narrowed from slightly in front of base, usually sub- punctate at base; apex emarginate, the anterior angles not prominent; sides rounded, the margin narrowly reflexed, the posterior lateial setigerous jiuncture about equidistant from basal and lateral margins; transverse impressions obso- lete; median line fine, subentire ; basal impressions sliallow and rather feebly defined, the inner linear, the outer forming a broad depression ; base tiuncate; hind angles rectangular, not carinate. Elytra very slightly wider than the thorax, striate; strise entire, punctate, sometimes very finely, the scutellar stria without ocellate puncture at base, the eighth with the row of ocellate punctures narrowly interrupted at middle; intervals flat. Body beneath black, impunc- tate. Legs black; anterior and hind femora with two, the middle with four setigerous punctui'es along the inner margin ; tarsi not grooved on the outer side. Length .27-.32 inch ; 6.75-8 mm. Very closely allied to confusa, from which it differs by the better defined basal impressions of the thorax and the punctate elytral strise. The ptinctuation of the latter is subject to some variation, being usually fine and not clearly defined, although in one or two examples seen it is very distinct. That of the base of the thorax is very feeble, in some specimens obsolete. The basal impressions of the thorax, although better defined than in conftisa and protensa, are much less distinct than in polita. It occurs in Colorado and New Mexico. 43. A. coeleb$>» n. sp. — Form rather elongate, nearly oval, convex. Color above seneous, shining, the inflexed portion of the elytra more or less tinged with green ; surface very finely alutaceous.

Length .29-.31 inch ; 7.25- 7.75 mm. Witli the exception of fallax, this is the only species having two setigerous punctures along the inner margin of the middle femora, in which the second and third antennal joints are carinate. From tlie latter species it is at once recognizable by the absence of an ocellate j)uncture at the base of scutellar stria, as well as by other characters. The punctured elytral strife are of rare occurrence in the present subgenus. Described from five males from Osoyoos, British Columbia. P^or the example in my cabinet I am indebted to the generosity of Mr. Chas. Liebeck. 49. A. polita Lee. — Oval, moderately convex. iEneons or nigro-teneous, sometimes distinctly bluish, shining.

Elytra only very slightly wider than the thorax, finely striate; striae entire, impunctate; scutellar stria without ocellate puncture at base, the eighth with row of ocellate punctures not widely interrupted at middle ; intervals flat or nearly so. Body beneath black, impunctate; prosternum rounded at tip. Legs piceous or rufopiceous, the femora darker; front and hind femora with two, the middle with four, setigerous punc- tures along the inner margin ; tarsi not grooved on the outer side. Length .25- .28 inch ; 6.25-7 mm. A well marked little species, readily distinguishable from the others with the second and third antennal joints carinate by the deeper basal impressions, the outer of which is oblique, as well as by its smaller size. It occurs throughout the Middle States, being known to m<' from as far east as Pittsburg, Pa., and extending northward to Lake Superior and westward to Colorado. TEAN6. AM. KNT. SOC. XXXIV.

[Note. — This family of flies was taken up for study and revision by Mr. Darlington while a senior student in the University of Idaho. At the time of his graduation in June, 1907, he had nearly finished most of the genera, includ- ing the drawing up of descriptions of the species, new and old. At this time his ai)pointment as horticultural inspector in an important field at Wenatchee, Wash., necessitated his immediate departure. As we had assumed obligations on all sides by borrowing material, there was no course open to me but to complete the work, which after some delay I have done. My part, aside from a general review, has been to work up the genera Leria and Siligo, and to prepare the illustrations. The new genus Siligo and its two species, and the new species of o( Leria (glauca), shouM be credited to me; the other new genus, Por.sewHS, and the remaining new species, six in number, should be credited to Mr. Darlington, whose industry and keen discrimination left little for me to do as far as his time I)ermitted him to go. — J. M. Aldrich.] This small family of Acalyptrate Muscidse is readily distinguished by the following characters: wings with auxiliary vein and second basal cell distinct, and a row of spines along the costa ; vibrissa? present; fronto-orbital bristles only one or two ; all the tibise with preapical bristles. Czerny, from a slightly different view point, defines the same group as follows : "The Helomyzidje belong to that series of groups of Acalyptratse which possess convergent or crossed (also called decussate) postvertical bristles. They are distinguished from all the other groups of this series by the simultaneous occurrence of vibrissse and an entirely separate auxiliary vein." The postvertical bristles are located on the back of the head, somewhat behind the ocelli, and are easily seen. For practical purposes the costal spines are almost sufficient to distinguish the family, but these do occur in a few species outside the family, especially in Ci/rtonotum, Ccenia and Fucellia, of our fauna. Cyrtonotmn (PI. IV, figs. 8, 9) has a short first longitudinal vein, united towards the tip with the auxiliary; Ccvuia has the typical Ephydrid face, and the second basal cell united with the discal ; while Fucellia has a row of fronto-orbital bristles extending to the base of the antennse, some six in number. TRANS. AM. KNT. SOC. XXXIV. MARCH. 190S. 68 AMERICAN DIPTKRA. The costal spines in Heteromyza are said to be very small, but there seems to be no good reason for regarding this as a North American genus, and we have not taken it into account. The larval habits are known in only a few cases in our fauna. Some of the species are found in caverns, where the larvae are said to breed in the excrement of bats. The adults of others are found about the mouths of holes occupied by rodents; other species are adapted to life on sand dunes. The known habits are mentioned under the separate species. Tlie classic pajjcr on the family is Loew's " Ueber die europiiis- chen Helomyzidse uiid die in Schlesien vorkommenden Arten der- selben," published in the Zeitschrift fiir Entomologie, xiii, 1-80. The work bears the date 1859, but as determined by Osten Sacken and Czerny it must have been published in 1862 or early in 1863. There apjiear to be no names of about that period conflicting with Loew's, hence the exact date is not of great importance. Schiner's treatment of the family in Fauna Austriaca, Diptera, ii, 20-35, 1864, really antedates in its preparation the paper by Loew ; hence it is practically superseded by the latter, especially in the matter of genera. The only other general work on the family is a recent one by Czerny, " Revision der Helomyziden," in Wiener Entomologische Zeitung, xxiii, 199-244 and 263-286, published in 1904. This includes the Helomyzinse (only the genera Helomyza and Allo- phyla), being Part I of a work as yet unfinished. The descriptions of the American species are quoted ; one useful feature of the work is a set of notes on Walker's types of Heloniyzid^e, showing that none of the species belong to the family at all, unless it may be among tlie small number of which the types are now niissing. Nearly all are Sapromyzas. Loew based his classification mainly on characters derived from the bristles ; hence this was the first family in which chaetotaxy was used, and that long before the introduction of the term. The bristles which by their variability afford generic characters are first of all the dorso- centrals, which occur in all the numbers from one to five ; the humeral and propleural (either one each or absent) are also useful. The figure on Plate III shows the position of the various parts and bristles of the thorax. Important specific characters are found in the number of sterno- pleural bristles, the presence or absence of hair or bristles on the Trans. Am. Ent. Soc, Vol. XXXIV. PI. III.

It is very unlike Curtonotum. While the course of the suture over the middle of the dorsum is not verv apparent, either in this or Helomyza, the indications are that in Helomyza there is only one bristle before the suture, while here there are two, and only three behind.

When in the fall' of 1901 I published in the Transactions of the American EntomoJogical Society a paper on the Aulacin^e of North America,* I intended it as the first one of a series of three papers, which I expected shortly to complete, one on each subfamily of the Evaniidie. Through many intervening circumstances this 'sign has been frustrated, but out of it has grown the present ■aper. This contribution deals primarily with the Evaniinse, and con- tains as complete a monograph of the North American species of that subfamily as I have been able to prepare. But I have found a study of exotic genera and species necessary to a satisfactory con- cept of the classification and relations of the group. Indeed, the variations of form shown by the members of this group and tlieir comparison with each other and with other groups, native and exotic, has been to me the most interesting part of the work, and I trust that I may be pardoned if I have laid more stress on it than is customary in purely systematic works, where often little attention is paid to characters not found desirable for use in keys. As a second part of this paper I have embodied the result of my study of exotic forms. Here are included descriptions and remarks on the genera and species of the world, a table to the genera, and finally a table to all the described species whose generic position I could with reasonable certainty identify. The latter have been compiled almost entirely from literature, which is I believe the only practicable method, because no one person can expect to accumu- late even a large proportion of the species of the world. These certainly must prove unsatisfactory, and must contain many errors, for the descriptions are often very incomplete, and it is difficult to compare those drawn uj) by different authors. But I hope that * Trans. Amer. Ent. Soc, xxvii, p. 319. TRANS. AM. KNT. SOC. XXXIV. (13*) APRIL. 1908. 102 FAMILY EVANIID.E. they will be of some real service to students desirous of identifying exotic species, and who at present must perforce wade through a great mass of more or less unsatisfactory descriptions, in several languages and innumerable publications. In preparing them I have used my best judgment in selecting characters that would be reliable and easy to use, but have of course been greatly hampered in this respect by the limitations of the descriptions. In such cases as I have been able to examine the species in question, matters have of course been much expedited. I shall begin the paper with a short consideration of the family as a whole ; then of the Aulacinse, tabulating the genera of the world and in part supplementing, in part revising, ray former paper on the North American species. Then I shall take up the Fo^ninse, treating it bi-iefly. I regret tliat at present I see no prospect of being able to prepare a more complete monogra})h of our North American species of this subfamily. In perhaps no group that I have studied have the characters been so variable and difficult of tabulation, so that it would require a very considerable amount of time and study. Then will follow the parts on the Evaniinse as above described, and I shall conclude with a catalogue of the species of Evaniinse of the entire world, distributed according to their proper genera. I wish to express my obligations to Professor Comstock of Cornell University, who has placed at my disposal in the entomological laboratory of that institution, where most of this work has been carried on, every facility for study that could be desired, and has kindly read the manuscript : to Dr. A. D. MacGillivray, also of Cornell University, for constant assistance, suggestions and courte- sies of many kinds, and also for reading the n)anuscript: to the authorities of the United States National Museum for the loan of the very valuable collection of Evauiidte belonging to that Museum: to the American Entomological Society for the loan of many speci- mens; to Mr. C. T. Brues and Dr. P. P. Calvert for the presenta- tion of several specimens: to Mr. Henry L. Viereck for the pres- entation of numerous valuable specimens, particulai'ly of North American Hyptia, and some undescribed species from British Guiana: to Mr. G. V. Hudson of Wellington, New Zealand for the presentation of two species of Fo^ninaj including the type of tlie genus Pseudofcenus : to Professor Herbert Osborn, Professor E. D. J. CHESTKK BRADLEY. 103 Sanderson, Mr. Wnj. Beutenmiiller, Professor Carl F. Baker, Dr. A. D. Hopkins, Mr. Ericli Daecke and others for the loan of numerous specimens: to Mr. C. S. Spooner and AFr. H. J. Ham- mond for assistance with the manuscript. The figures of wings on Plates XI-XV inclusive were made as follows: the wings were removed from the right hand side of the insect, mounted on slides and then photographed. Blue-prints were made on drawing paper coated with blue-print solution. The out- lines of the veins were then drawn on the print with water- proof India ink, and after thorough drying the print was bleached in a strong solution of potassium oxalate, leaving the ink drawing on a white background. Thus almost mechanical accuracy was obtained in the representation of the thickness and position of the veins. Figs. 67, 82 and 87 were co})ied by a similar method from published figures, inasmuch as no specimens of these genera were available. Figures 18, 19, 62, 63 and 64 were drawn free hand. The remain- ing drawings were made with a camera lucida. The drawings on Plates Vn and VHI were all made to the same scale, as were those on Plate IX. The claws on Plate IX were mounted on slides, hence present a somewhat different appearance from what would be seen in situ. Plate V is from direct photomicrographs. I have been able to study specimens of all the described genera except the following: Evanisciis Szepligeti, Evaniellus Enderlein, Anlacinus Westwood, iSeinenoivia Kieffer and Aulacus Jurine ; also of all the North American species of Aulacinse and Evaniin?e except Hyptia brevicalcar Kieffer, Aulacus erythrogaster Is.\effer, Pristaulacxis flavipes Kieffer. The Evaniidae are an anomalous family of parasitic Hymenop- tera, probably of very ancient stock, and as is often true in such cases, although well represented in number of species, the individ- uals are almost invariably to be counted as rare insects, and are not usually well represented in collections. Because of their anomaly they have formed, as I have before remarked, a dumping ground for very many peculiar forms whose relationships have puzzled investigators. In this way the following genera and perhaps others have at one time or another been included in the family, in addition to those we at present include : Felecinus, Stephanus, Mcgischus, Paxilloma, TrUjonalys, Monomachus, Ophionellus, Meyalyra, Capi- tonius, Ccenoccelius, Leptofcenus, etc. To-day most authors are TEAKS. AM. ENT. SOC. XXXIV. APRIL, 1908. 104 FAMILY EVANIID^. agreed in restricting the family to the scope recognized in this paper, except that some include with it the Stephanidge. While I think the latter are sufficiently distinct to form a fan)ily by them- selves, I believe they really are closely related to the Evaniidse, par- ticularly through the Foeninse. There is a similarity in wing vena- tion, and the insertion of the abdomen in Stephanus is on the lower part of the propodeum, but above the coxae. Even the habitus is somewhat similar. It is not improbable that the Foeninse may really be more closely related to Stephanidse than to Evaniinee or Aulacinse, and should really form a subfamily of the former rather than of the Evaniidse. Although really I think all of the sub- families here recognized are entitled to family rank. There are two characters that are usually employed in distin- guishing the Evaniida3. These are the presence of the cell C in the front wings (Fig. 69 j, and the insertion of the abdomen on the propodeum far al)ove the posterior coxse. Neither are absolute, and may be used only in conjuction with other characters. The Ste- phanidfe, as before mentioned, have a distinct costal cell, while several genera of Braconidic have the abdomen inserted on the propodeum far above the coxae ; some of the Stephanidge less dis- tinctly so. The Roproniidae have a distinct costal cell, but the abdomen inserted normally. In designating the wing veins I have employed the system pro- posed by Comstock and Needham.* I do this because I believe that the venation thereby takes on an intelligible significance. The veins are, I am convinced in the main, correctly homologized with those of other orders. I intend to employ this system as far as possible in my future studies of the Hyraenoptera. I refer the reader who is not familiar with it to the paper of Comstock and Needham just cited, and for its application to the Hymenoptei'a, particularly to a paper by Dr. A. D. MacGillivray f on the wing venation of the Tenthredinoidea, where the subject is treated very clearly in Sections II and III, pp. 574 to 583. An appreciative and careful study of these sections and their accompanying figures will I am sure make the matter clear to any one. *" Wings of Insects," J. H. Comstock and J. (i. Needham, Amer.

In Fig. 73 it will be seen that the medial cross- vein and the second branch of media form apparently a single vein with no indication where they join. In such cases where two different abscissas are joined end to end with- out indication of the place of union, I have designated the entire vein thus formed by the name of each abscissa connected by "and", or if three or more are thus joined, use a comma between the first two and "and" between the second, as m and M2, or, again, I^s, R3+4 and R3. The -f- mark of course is only used where two or more veins unite side by side, as R4+5 + Mi-[^2- On Plates XI-XV inclusive are arranged figures of all the types of wings known to occur in the family, in what I believe to be an order ascending from the most generalized to the most modified, especially within each subfamily. The Aulacinse are very evidently the most generalized. Take for example Aulacinus (Fig. 67), R4, R5 and all of M2 are present. Omitting for the present the Fceninfe (Figs. 72-74), we find in the wing of Evania (Fig. 76) only a slight modification. R5 is lost and also the transverse part of M2. M has migrated far forwards along the radius, carrying with it m-cu. In this subfamily modification then proceeds by atrophy, until in Evaniellus (Fig. 87) only C and Sc are left. The Faniinse (Figs. 72-74) we may look upon as a side line. We cannot com- pare the degree of their specialization with the others, because it has been in an entirely different direction. It seems reasonable to suppose that they may have arisen as an offshoot of Aulacime (compare Figs. 71 and 72), or they may have arisen from some- where among the ancestors of the Stephanidje. At any rate in wing venation and other characteristics they are highly modified. Of course I do not base my conclusions as to the relations of these groups solely on the wings, but these are easy of illustration and description, and in all more reliable for comparison than any other single character, hence I emphasize them here. L'Abbe Kieffer* criticizes the table to the subfamilies of Evanii- dte that I published in my former paper, on the grounds that the characters given do not apply in all cases. But I think that his criticism is unfair, since the table was intended only for the North American forms, for which so far as I am aware it holds good. All * Spec. Hyiii. d' ICur. et d' Aljit-'r., vii, bis, p. 377. J. CHESTKR BRAULEY. K'7 the exceptions urged are for exotic species. His own table pub- lished in the same place is open to tlie same objections. Thus under his tribe Evaniiuie he says: "Nervure basale aboutissant au stigma, rarement evanouie dans sa partie superieure." In the genera Hyptia, Setmeomijia, Semieodofjaster, Evaniellus and sometimes Zeii.v- em?uVf, the " nervure basale " is wanting. Again he says : "Abdo- men ellipsoidal chez le male." In Hyptia and others the abdomen in the male is round and indistinguishable from that of the female in shape. I think that the characters employed in the following table will be found constant, except that I am not certain whether the folding of the wings is constant in all Fwninaj or not. It is in all cases that have come under my observation. TABLE OF THE SUBFAMILIES OF EVANIID.E. 1.

But Gas- teruption of Latreille (1797) is a nomen nudum— no species being mentioned. In 1798 Fabricius describes Fcenm with jaculator and imectator as species. Latreille in 1802, Hist. nat. Crust, and Insec, iii, 329, says: " J'avois etabli ce genre avant Fabricius, sous le nom de Gasteruption. ; niais, comme ce dernier mot est trop dur, j' adopte avec plaisir la denomination de ce naturaliste." As before remarked, the Fcx'uina' show unmistakable relations to the Stephanidse. The wing of Hyptiogaster is the most generalized in the sub- TRANS. AM. ENT. SOC. XXXIV.

In Pseudo- fmius (Fig. 74) the condition is the same, except for an additional step, the vein M4 being lost and cells M3 and M4 thus thrown together. The habitus is similar in all the species that I liave studied, the proportions being always slender, the neck long, and the posterior tibite very strongly clavate. But not in the genus Hyptiogaster, at least not in H. humeralis, in which the form is stouter, the neck short and the posterior legs stout ; the femora very stout, as though for leaping ; the tibiae stout but not clavate ; the tarsi very short, exclusive of the claw, less than one-third as long as the tibise, the second and third joints being extremely short, much broader than long, while the claw is quite large. The mouth parts are much ' enlarged and used for sucking (Figs. 20-21). The claw (Fig. 43) is always simple ; the mouth parts are shown in Figs. 20-23. An interesting character is found in the longitudinal folding of the wings, as in the Vespoidea. Outside of these there is only one other genus of Hymenoptera known to have this habit, namely Leucospis, a Chalcid. A quite extensive account of the life history. of i^cen?i iiicertns Cresson.

It seems to be more common in Nevada, and to extend eastward into Colorado (West Cliff), and northward into Oregon (Mt. Hood) and Washington. Ineertus is the common form in Colorado (type locality) and is also recorded from New Mexico (Beulah, August 17th, Dr. Skinner; July 11th, T. D. A. Cockerel!), from Oregon (Mt.

The prevalent color is black, and this is sometimes varied with red, less often with yellow and sometimes a little white on the legs or antennae. The head, body and legs are covered with a short yellowish or whitish pubescence, sometimes thick enough to obscure the sculpture, especially on the metaveuter, producing on the sides, head and propodeum of some species a bright sflvery sheen. The head is transverse to tranverse-quadrate, very different from the head of either of the other two subfamilies; it is most like that of Aulacinse, but when seen from the side is less convex in front, and pointed or attenuated above instead of rounded ; in the Foeninae the head is long, oval, and so attached as to normally throw the face in plane with the dorsum ; in Evaniinie the face is always at right angles to the plane of the dorsum. Posteriorly the entire head is concave, usually deeply so, and the rim where the concave posterior part meets the convex anterior is usually accentuated by a little ridge marking what I have called the [)osterior angle of the occiput and temples; in the Aulaeinse it is somewhat similar, but in the P^(onina' J. CHESTER BRADLEY. 1 2l> the posterior concavity is reduced to a small cup like pit in which the neck is inserted, and the rest of the posterior (in this case lower) portion is convex and not separated from the temples. Seen from above, that is looking squarely down on the vertex (Figs. 10, 13 and 15), the head of Evaniinte is transverse to almost transverse quad- rate and shows a varying distance between the eyes and the poste- rior margin of the occiput. The sides may be inflated, square or rounded behind the eyes. The ocelli are three in number; the anterior one sometimes somewhat transverse. Whether or not the posterior ones are nearer to each other or to the compound eyes is a character of specific value. The eyes from this view may be promi- nent or not. The profile of the head varies in shape (Figs. 9, 14, 16 and 17). It is nearly always broadest below the middle, and narrowed, even bluntly pointed at the vertex. The forehead may be plain or convex. The eye is always more or less .slanting, mak- ing the temples broadest below, and it is of varying length, extend- ing in Evaniella calif ornica (Fig. 9) scarcely below the insertion of the antennae, but usually much below this, never, however, very closely approaching the mandibles. From in front the head varies from round to nearly triangular, or may be somewhat oblong, as in Acanthinevania jyrinceps and A. longigena, etc. The eyes from this position may or may not be prominent; their inner margins are parallel, or somewhat converging. The mandibles have one or more blunt lobes within. The clypeus is usually mucronate or obtusely pointed, not separated from the face above, but sometimes set off laterally by a short groove ; together with the face it is often swollen or broadly convex. There may be a longitudinal carina in the middle of the face and one on each side, and frequently in in Evaniini a short longitudinal interantennal carina. The an- tennse (Figs. 55 and 59) are situated at varying distances apai't, usually about the height of the middle of the eyes, but sometimes as low as the base, depending more on the length of the eves than difference in the actual position of the antenna). The scape in Evaniinte and at least sometimes in Hyptiini is much longer in the female than in the male. The second joint is ordinarily very short, sometimes not so, and this I have always called the pedicel. 1 have counted the flagellum as beginning with the third joint, the rela- tions of which to the fourth are of specific value. There are thir- teen joints altogether in each sex. In the female the flagellum is TEANS. AM. ENT. 80C. XXXIV. (17) APKIL. 1908. ]30 FAMILY EVANIID^. sometimes thickened, [)articularly in Semwomyia, where it is strongly incrassated beyond the middle, see Fig. 55. The forehead is more or less convex in Hyptiini, but in Evaniinse it is concave, forming a distinct basin in which the two antennae are inserted, and this is bordered below and usually laterally by a distinct carina or rim. I have studied the mouth-parts from glycerine mounts of all the genera but two (PI. VIII), and find that the maxillary palpi are 5 jointed, the palpiger distinct, and the labial palpi usually 4-jointed, in Hyptia 3 jointed (Fig. 37). In Evania and especially in Hyptia the third joint of the labial palpi is strongly inflated, and sub-tri angular (Figs. 28 and 29) ; the labium in Evania is broadly oval, highly chitinized and conceals the rather short ligula; this is also true in Hyptia, but in that genus the labium is broader, rather pear- shaped ; in Acanthinevania (Figs. 26) it consists of two narrow chitinized plates, which do not conceal the long lingula ; in Evani- ella (Fig. 35) the arrangement is similar, but the labium is a little broader; in Szepligetella the ligula is long, but the labium broad as in Evania. The neck is short, shorter than in Aulacinse and much shorter than in Foeninse, so that the head normally covers the collar or pro- notum (Fig. 18). If we remove the head and look at the thorax from in front (Fig. 19), we will see the pronotum as an irregular transverse piece forming the upper and side margin of the cavity vacuated by the neck, extending down laterally in a narrow point almost to the coxae (Fig. 19). The upper margin is more or less arcuate, sometimes nearly straight and extends back below the raesonotum to the tegulse. The shoulders, spoken of as the humeral angles (Fig. 19), may be entirely rounded, or sharply angled, and this character is very useful in classification. Below the cavity of the neck, and somewhat depressed, are two oval sclerites, which rep- resent the propleurie (Fig. 19), and adjoin the procoxa) below; the latter are in juxtaposition (Fig. 19). If we examine the dorsum from above we will .see the mesonotum as a large piece, rounded in front and extending backward to behind the anterior wings, where a straight transverse suture separates it from the scutellum. The latter is indistinct in North American Hyptiae, so that the mesonotum and scutellum superficially aj)pear as one piece. The mesonotum is of varying degrees of convexity, but never gibbous, as in Aulacinie. The maximum number of J. CHESTER BRADLEY. 131 gj'ooves on it are as follows : a regularh' curved groove on each side extending from the posterior to the anterior margins, spoken of as the parapsidal groove: a short longitudinal groove on each side between these and the tegulfe, called the lateral grooves : and two very short grooves in the middle extending backwards from the anterior margin, called the anterior grooves. These are all present in E. appendiyaster, and form good characters for separating species. The mesopleurse (Fig. 18) are oblique rhomboidal sclerites, partially separated from the mesoventer only by an obscure groove. An oblique sulcus traverses it in which the femora of the middle legs may be fitted, when drawn up, and which together with the poste- rior part is highly polished in Hyptia. Anterior to this sulcus the sclerite is rounded out and full, forming what I have called the anterior swelling. The entire venter is usually more finely punc- tured than the other sclerites. The middle coxse occasionally are placed far posteriorly, thus prolonging the mesoventer; the latter is mesally divided by a longitudinal suture, and ends between the coxse in a l)ifurcate process or furcula. The middle coxae are placed wider apart tlian tlie posterior, but the ratio of the two distances varies in ditterent species. The metaventer is similar, but undivided from tlie metapleurte, and without a medial sinus. The posterior coxae are more or less closely placed, and the furcula in which the metaventer ends is of primary specific importance; the lobes or tynes may be mere knobs (as generally in Hi/ptia'), or may be elon- gate, parallel (Fig. 64) or divergent (Fig. 6H) processes. The metapleura (Fig. 18) is roughly triangular, with its apex beneath the posterior wings; it is often not separated posteriorly from the propodeum. The scutellum is a large nearly quadrate piece. Directly behind it and sunk in a deep depression, forming scarcely more than a transverse line, is a sclerite tiiat I have called the metanotuni, although it may be the postscutellum (Figs. 62 and 63). If looked at from the side tliis sclei'ite seems to form the bottom of a narrow groove, which, in Evaniime, has very steep walls, in Hyp- tiini these walls are more sloping, a difierence illustrated by Figs. 62 and 63. The distance from the nietanotum to the insertion of the petiole varies, but is approximately and on the average a little less than the length of the petiole, and about the lenglli of the scutellum ; behind this the propodeum is produced a short distance and then TRANS. AM. KNT. SOC. XXXIV. APRIL. 1908. 132 FAMILY EVANIID^. slopes off more or less abruptly into the posterior face or truncature. which may be flat, convex or concave, with a niesal angle. The propodeum is almost always reticulate, except above the petiole, where it may be punctured or rugose. In the genus Hyptia the shape of the reticulations on the sides just behind and perhaps extending over the metapleura? is of prime specific importance (Pi. V). The abdomen in the female Evaniini is about the shape of an isosceles triangle, base uppermost, and the outer angle with the pygidium produced into a point from which the ovipositor may be exserted (Fig. 18). In the male it is narrowly oval. Always in Hyptia and usually in all Hyptiini the abdomen of the male and female are alike, round and without any visible sign of ovipositor ; often it is impossible to distinguish the sexes. In both tribes the petiole is long, flattened below, and often striate or punctured, espe- cially on the sides ; it is not enlarged apically and is distinctly sep- arated from the rest of the abdomen. The abdomen proper is highly chitinized ; in every species I have seen, smooth, black and polished ; it is very strongly compressed ; the ventral segments only narrowly exposed ; these also chitinized and forming a sharp mesal keel at the lower edge of the abdomen. The ovipositor is never exserted. The posterior coxse are grooved above for the reception of the femora. In all genera except Hyptia, and probably Evaniellus, the posterior legs are very elongate (Fig. 60) ; in the former genus they are only the length of the body, and the posterior tibi?e are distinctly thickened at theii' apex (Fig. 61). In two genera the [Misterior legs bear numerous sti'ong spines in rows; also in Hyptia there are rows of very minute spines, visible only with favorable light and under a strong lens, or more distinct in one species. The posterior tibise are armed with two long spurs, and the propoi'tion of tlie longer of these to the metatarsus (first tarsal joint) is of specific importance. Tlie proportion of the metatarsus to tlie following joints is also important, but is nearly fixed in Jfyptl((. In all genei'a thei-e is a distinct tooth within the tarsal claw (Figs. 44-54), and the shape and position of this and its angle with the outer ray is of specific value in some genera, but nearly constant in Hyptia. Some- times as in Zeuxevania. (Fig. 50) and Sema'omyia, (Fig. 51 ) the claw is l)ifi(l, and the inner ray much stouter and longer than the outer. J. CHESTKK BKADI>KY. 133 Tlie wings of the subfamily are of special interest, inasmuch as we find in them a very complete series showing specialization by atrophy, from the condition found in Evania as the most generalized to that found in Evaniellus at the other end of the group. The wing of Evania appendigaster (Fig. 76) is as generalized as any I know of in the subfamily, with the exception of a few which show Rj more distinctly (see Fig, 75). C and Sc + R + M are separated as in Aulacinse and Gasteruptioninse, forming a distinct cell C; R3 after separating from R4 bends either obtusely or acutely or at right angles upward, and reaches the margin from one-third to two-thirds the distance from the stigma to the apex, but the angle at which it bends seems not to be entirely constant within a species. As has been stated R4 is present in the most generalized type (Fig. 75), but it is always partly atrophied, and usually there is only a stump or no trace at all of it left. R5 is never present. M separates from R within or close to the stigma, running almost backward till it reaches m-cu when it turns at right angles; m-cu is thus very long, and the cell R -f- 1st Ri is diamond shaped. But in Zeuxevania (Figs. 80-81) M separates from Sc + R about two thirds of the way from the base of the wing to the stigma, or the base of M is entirely wanting, if present it runs backward a short distance and joins m-cu, this vein being much shorter than in Evania, and con- tinuing in an unbroken curve with the longitudinal part of M.

Hab. — Distributed throughout the world, and almost everywhere the most abundant species. It is believed to have originally inhab- ited Europe from whence it has become naturalized in almost all countries along with the Blattidse on which it is parasitic. In the United States it seems chiefly confined to the east, and is especially common in some of the larger cities. Say's tmicolor was from the Rocky Mountains, but we have no other records from that far west. It has never been taken here at Ithaca, nor have I seen specimens from north or west of here. Evania urbaiia n. sp. (Figs. 45, 66, 77.) '^ , 9 . — Black. Sericeous pubescent, especially the face and propcideuni, shin- ing silvery in certain lights. Face subconvex below the antennse, which are situated rather far apart in a deep and very well defined basin, the anterior and lateral margins of which are limited by a distinct ridge which starts from a cen- tral point on the face below the antennae, running on each side outward and upward, to a short distance from the eyes, where it turns inward again, becom- ing lost before reaching the ocelli; another carina extends longitudinally be- tween the antennae traversing the whole length of the basin ; as thus defined, the basin is narrower than in E. app endig aster ; from somewhat within the lower angles of the eyes a groove extends on each side to the inner angles of the man- dibles, which, together with the carinse above described, enclose a shield-shaped area embracing the entire face, which is subcoarsely and regularly longitudinally striate, the strise converging somewhat towards the apex (clypeus), which appeals as a very small triangular smooth and polished piece; the temples are roughly substriate, below the eyes the cheeks are striate similarly to the face, the stria- converging towards the face and mandibles; the vertex is covered with large punctures; the ocelli placed close together, the central ones much smaller than the other two, between the central and each lateral ocellus is a small smooth prominence partly surrounding each ocellus, part of which it at first appears to be; eyes small, prominent, removed by a little less than their length from the mandibles; temples narrow, wider at the base of the eyes; antennas filiform, somewhat thickened in the female ; average measurements as below : Scape Fed. 3 4 5 6 7 8 9 10 11 12 13 Flag.

Abdomen of the female subtriangulai-, with the apical angle angle slightly produced into a short process containing the ovipositor; petiole one-half the length of the abdomen, longitudinally striate; the segments smooth, polished ; the second almost twice as broad as the third ; the second, third, fourth and fifth segments fully exposed, the latter broadly emarginate dorsally, exposing a part of the sixth and seventh segments, which form the process already described ; edges of the last two segments and apex of the ovi- positor finely ciliate. Length 7 mm. This pretty silvery shining species is very different in appear- ance and characters from E. appendig aster, or any others that 1 know. The most obvious characters are the striation of the face and the narrow abdomen of the males, but there are many other important differences. In all I have seen over eight males and .seven females. Five of the males were collected by Mr. AVitmer Stone on the windows of his house in Philadelphia. As all the other specimens have also been taken in large cities, I have applied to it the name nrbana. Mr. Liebeck sends me five more specimens taken on the windows of a house in Philadelphia. It is of course possil)le that it may represent another exotic species, migrating similarly to E. appendig aster. The front legs and antennse are sometimes_ more or less pale.

The labium (Fig. 35) is narrowly oval, not concealing the ligula ; the third joint of the labial palpi is ovoid, not triangular, longer than broad ; the eyes are in E. californica (Fig. 9) extremely small, so that they do not reach much below the base of the an- tennse, normally they are longer (Fig. 16) ; the antenme are fili- form, situated on a convexity of the forehead, or if in a slight con- cavity there is at least no distinct rim below. The metapleurse have at most a polished spot on the upper corner, often none at all ; the sides of the propodeum are not peculiarly sculptured ; the furcula is usually with more or less divergent short tynes, often obscured by vestiture. The posterior legs are long, and without spines. The wings in all species known to me are hyaline; and the veins R4_ M beyond m-cu, Mi-^s, Mi, M2 and m are wanting, or present only as a trace (Fig. 83). The shape of the abdomen is more or less intermediate between Evaniini and Hyptiini. The abdomen of the female is quite or nearly round, never distinctly triangular, but in one specimen is nearly so; there is sometimes a slight production of the pygidium into a point containing the ovipositor. The abdomen of the male varies from round to narrowly oval {E. neomexicana). So far there are only five species of the genus known, three from North America, one from Cuba and one from British Guiana. But it is probable that maqy, at least of the South and Central Ameri- can, Evanise really belong here. TABLE TO THE NORTH AMERICAN SPECIES OF EVANIELLA. 1.

Wings hyaline, veins K4, Mi + 2, Ml, M2 and m wanting, their position indicated by a faint trace; R;{ obtusely angled. In the male the petiole is smooth ; about two-thirds the length of the broadly oval, nearly orbicular, polished abdomen ; segments 2-6 inclusive fully exposed ; the third about two-thirds the width of the second. In the female the slightly pitted petiole is about one-half the length of the nearly orbicular, obliquely truncate, polished abdomen ; segments 2-5 inclusive fully exposed, the second making up about one-third of the exposed area, almost three times as wide as the third segment. The color of this species is very variable. It is barely possible that two species may be included, the one of northern distribution and black in color, the other southern and with more red. The color, however, intergrades, and I can find absolutely no structural difference that will separate them. I have in all before me eight specimens, all from the United States National Museum collection. Four specimens are black entirely, except with forelegs testaceous beyond the trochanters, and two of them have some reddish on the dorsum. One specimen is mixed with reddish- brown all over the thorax and legs, and the base of the antennie, and the apex of the J. CHESTER BRADI.EY. 145 petiole white; another has the first five joints of tiie antennje ami the front and middle legs brown, the trochanters and apex of petiole white, and the upper part of the thorax i-ed ; another the scape, lower part of the face, and upper part of thorax red, and the front legs brownish ; two others have the upper part of the thorax red, and the apex of the petiole white. In the " Canadian Entomologist," vol. xxxiii, p. 304, Dr. Ash- mead states that he has recently recognized Evunia unicolor Say as distinct from appendig aster, differing in punctuation. From the labels on his specimens it is evident that he refers to the northern or black form of this species, semieoda, which differs veiy markedly from appendig aster, but very certainly belongs here and not to Evan'm. In the "Canadian Entomologist," vol. xxxvii, p. 64, 1 state in speaking of Evaniella, "Here also belongs and stands as type the species which Dr. Ashmead calls unicolor Say, but is not that species. Say's description applies to E. appendig aster, which could easily have spread into the interior with the early settlers, inasmuch as it is parasitic on cockroaches." After receiving a letter from Dr. Ashmead assuring me of his conviction as to the correctness of his determination, I looked over the matter as^ain and came to the conclusion that he was right, and so wrote to him. Inasmuch as there was doubt concerning the identification, and since the type was destroyed, it seemed to me right to follow^ his determination. But recently it has seemed to be so impossible to identify the specimens in question with Say's description, that I have decided to follow my former course and describe it as new, leaving Say's unicolor as a synonym of appendi- gasler, or as a species which has not since been collected and which may yet come to light. I follow this course with great regret, not only because I do not wish to add unneccessarily to nomenclature, but because could I conscientiously do so, I should prefer to follow the judgment of an entomologist as experienced as is Dr. Ashmead. Say's description oi unicolor is as follows, the italics are my own : ■' Entirely black, immaculate, slightly sericeous. Inliahits the Uniterl States. Antennae as long as the body ; palpi piceous; thorax with verii few small punctures ; melathorax [propodeum] densely punctured ; wings liyaline, nervuies fuscous : n distinct nerviire passes from the dividing nervure of the cnhital and discoidul cellules to the posterior margin of the wing: abdomen much compressed; inipunctured. polished oval, ratiier longer tiian the petiole; posterior feet elongated. Lingth more tlian three-tenths of an inch. TEANS. AM. KNT. SOC. XXXIV. (19) APRIL. 1908. 146 FAMILY EVANIID^. " The proportions of the petiole, abdomen and posterior feet of this insect are nearly the same with tliose of appeiidigasfor Fabr. 1 obtained a specimen near the Rocky Mountains, and it is also found in Pennsylvania. The additional nervure is sometimes con- nected with the radial cellule by a faint, transverse nervure, so as to form a second cubital cellule." In semceoda the thorax is coarsely and thickly punctured ; in appendigaster it has very few small punctures. In semacoda the mesopleurse have the upper half smooth, a character that would not likely have been overlooked by Say; in appendigaster the upj)er part of the mesopleurie is only slightly less punctui-ed than the lower part. It is characteristic of semceoda as well as other species of Evaniella that the " nervure passing from the dividing nervure of the cubital and discoidal cellules to the posterior margin of the wing" (M14-2 fi'iid Ml) as well as the "faint transverse nervure" connecting it with the radial cellule (R4), "so as to form a second cubital cellule," and also m-cu and M are always and invariably atrophied (Fig. 83). In appendigaster and other species of Evania these veins are present, just as described in the description of unicolor, but in occasional specimens of ajypendi.g aster only, so far as I have observed, is R4 present, and then always partly atrophied, so as to appear, as Say says, as a " faint transverse nervure." The pi'oportions of the posterior feet of seiiueoda are not the same as in appendigaster. In semceoda the metatarsus is about as long as joints 2 -|- 3 -)- 4 together, in appendigaster only as joints 2 -|- 3. The joint bearing the claws is much longer in appendigaster than in semceoda. Inasmuch as appjeadig aster was a European species, it is highly probabte that Say would not have identified his specimens with it even if they agreed. He points out no difference between unicolor and appendigaster, and we have no evidence that he knew appendi- gaster from anytiiing except description. On the other hand it is possible that unicolor may rej)resent a native American species which is at present unknown to us. 1 have seen no specimen of appendigaster or semwoda from west of Georgia and Ohio, whereas Say described unicolor from the Rocky Mountains.

The color is usually black, but may be more or le.ss red or yellow ; the anterior and often middle legs are sometimes pale or brown, but the color is variable within the species. Clothed with a white or yellowish sparse pubescence, sometimes becoming so thick on the metaventer and coxse as to conceal the punctation. The head seen from above is transverse to transverse-quadrate, the anterior margin between the eyes appearing from such a view more or less convex, sometimes with a mesal emargination in which are placed the antennae (Fig. 12). In profile the head varies from narrow to broad, usually widest at or below the antennae, either flat or more or less pointed above the eyes; the latter are somewhat oblique, and the malar space is generally about one-half as long as the eyes ; the mandibles are short, and have a blunt tooth within ; the clvpeus is pointed in the middle, sometimes set off laterally by a short indis- tinct groove; from the upper margin of the base of the mandibles a carina is usually present running to the base of the eye, and then upward parallel to and slightly separated from the inner margin of the eye, to varying height, separating the face from the cheeks; the clypeus and face are usually somewhat prominent or gibbous; the forehead is fiat or convex, and the anteniite are not inserted in a basin, nor are there any carinee between or around them ; thev are 13-jointed and are either filiform, gradually and evenly thickened (Fig. 57), or short and strongly thickened beyond the base of the fllageilum (Fig. 58); the.se characters and the proportions of the scape to joints three and four together, and of the peilicel to joint three, I have found of specific value, although these distinctions are doubtless to a certain extent only sexual. The labium (Figs. 37 and 38) consists of a large, highly chitinized, broad, pear-shaped piece, beneath which the ligula is concealed and the palpi originate; the labial palpi are o-jointed, the terminal joint broadened, but not TEANS. AM. ENT. SOC. XXXIV. APRIL. 1908. 148 FAMILY EVAXIID^E. as much as the tliird joint ; the palpiger distinct. Tlie head behind the eyes and vertex is more or less narrowed, a carina of varying distinctness separating it from the gular regions. The neck is short. The pronotum (Fig. 19) consists of a trans- verse vertical piece, constricted in the middle and usually smooth and polished ; the lower edge is more or less produced forward into a short transverse collar; the humeral angles (Fig. 19) are promi- nent or rounded ; the upper edge is emarginate in the centre, the mesouotum fitting into the emargination ; the propleurse and venter are not distinct, but small and concealed beneath the head, as is always the case in the subfamily (Fig. 19). The mesonotum and scutellum form together a more or less convex area, and are sepa- rated from each other by a transverse straight suture that is often not plain ; the anterior and lateral grooves are absent, the parapsi- dal grooves are not present in an}' species in our fauna, or at least not more tlian a trace of them anteriorly ; in West Indian and other exotic species they are distinct, but when so are usually placed a little nearer the middle than in Evania ; the mesopleur^e have a highly polished impunctate or minutely punctulate area occupying more or less of tiieir upper surface (Figs. 1, 6 and 7); this area is generally broken above by a circular pitted area, and has usually some irregular pits in the middle; its shape and extent, and the depth and shape of a large oblique fossa or depression traversing the forward part of it, and forming a receptacle for the femora are characters of s])ecific importance; anterior to the depression the pleurae are swollen into an oblique broadly rounded ridge, the punc- tation of which is usually sparser than on the dorsum, but similar to the venter, from which it is not separated. This area I have spoken of as the anterior swelling of the mesopleurse. The meta- notum (Fig. 63) is a very narrow transverse strip, depressed between the scutellum and propodeum, the edges of which form gradually sloping walls for it (Fig. 63). On the metapleui-se there is ante- riorly a very narnnv punctured area, interrupted mesally, behind which there is an oblique well marked carina, parallel to and behind this carinie is a broad fossa of varying depth, and the natui-e of the reticulations in this fossa and on the propodeum just behind it is of great s[)ecific importance (PI. V); these may be long and narrow with few or no cross bars, or nearly square, and there may be from one to three rows; one or two oblique carinie may be present, one J. CHESTER BRADLEY. 149 oil the anterior edge of the region ; the other near the posterior edge; beliind this area of modified reticulations the entire propo- deum is hexagonaliy reticulate, except above the petiole, where it is punctured or otherwise sculptured. Tlie hind legs are inucli shorter than in the other genera (Fig. 61), about equalling the whole length of the insect; the coxee have an oblique groove without, much deeper than in Evania. The tibiae and sometimes the tarsi have among the pubescence rows of fine yellow spines; these are usually difficult to detect, and I have never .seen any in which they are prominent, as they are in Acanthine- vania, in which they are black and very much more abundant. H. amuzonica Schletterer is said to have the spines^ distinct. The tibia is thickened a little toward the apex ; the longer of the two apical spurs varies in the different species from less to more than one-half the length of the metatarsus ; the latter is longer than joints 2-4 taken together, and upon how much longer depend some specific distinctions; the tarsal claw is of moderate or small size, with a single tooth within (Fig. 54), shorter than the apical ray, and at a little less than a right angle to it; the size and angle of the tooth does not seem to differ in the genus, and hence offers no character for specific distinctions. The wings are hyaline, sometimes with a milky lustre, and there are present in the front wing (Fig. 86) only veins C, Sc -j- R -|- i\I, the stigma, Cu,Cui, and M4 ; where the two latter join a short cross- piece indicates the original position of the base of m cu and Cu: -f M4. Faint lines indicate the original position of some of the now atrophied veins, arranged as in Evania. The hind wings have only part of the vein R -f- M present. The sculpture of the petiole is a matter of prime importance; there is usually a tendency toward oblique ridging, at least along the lower part of the sides, but above it may be nearly smooth with oiilv a few punctures, or may.be finely longitudinally striate ; the length of the petiole is usually about equal to that of the abdomen, or sometimes less. The ab
