The specimen compared to the type also has the black of the fore and middle coxa replaced by red. In both color and sculpture this genus stands at the opposite end of the tribe of Lycorina. From that genus and from CKlorolycorina it differs in the oblique back of the propo-.

Compared to the description of alhijyes, a male and a female from Kansas differ only in color, the abdomen and propodeum being beautiful with tergites that are black entirely across the tips, the clypeus piceous and the coxae stramineous. She. - Polished with scattered, obscure punctures medially on tergites; clypeus much wider than long, deeply curved basally, broadly rounded and reflected apically; malar room approx. half as long as basal width of mandible; The face is about as broad at the clypeus, the eyes slightly converging below the antennae, very faintly projecting within; diameter of lateral ocellus, ocell-ocular and postoceUar lines about equal; temples and vertex rather strongly convex; notaulinot particularly strong butprescutum very long and low anteriorly; propodeum noncarinate but canaliculate medially; first tergite with carinae obsolete beyond apex; tergites 2-5 strongly tuberculate laterally, 2-4 with deep apical and basal impressions, interrupted in middle; extended part of ovipositor twice as long as first tergite; stigma narrow, radius projecting at basal two-fifths; inter- cubitus liaK as long as second abscissa of cubitus; nerve louse weakly broken around the lower third; behind basitarsusaslongas next two joints together, last joint slightly shorter than third; antennae about three-fourths as long as body.
The type has head, prothorax, upper posterior corner of mesopleurum, metathorax except pectoral, propodeum, and abdomen, black-spotted; legs pale modern, fore pair paler and hind pair darker, with fore coxae, all trochanters in front, hind and mid femora at apices, and all tibiae and tarsi whitish above, darker below, hind tibia and first two tarsal joints fuscous below and at apices . A female from Los Angeles, California is very nearly typical, while one from Lawrence, Kansas has entire pro- and mesothorax testacean, metathorax slightly darker, propodeum and abdomen spotted, the latter with apices of tergites black, leg scapula pale, stramineous, slightly darker basally and with hind tarsal joints narrowly dark at apex. The female from Lawrence, Kansas, closely resembles the female from the same locality, but is slightly darker throughout, and the hind tibia shows very faint indication of the type color pattern.
Polished with a few weak punctures on mesosternum, laterally on propodeum and in impression of hetergites, especially towards apex of abdomen; clypeus very broad and short with its apical margin so strongly reflected as to give the appearance of a section (this occurs to some extent in some specimens of hurgessi Cresson, while not evident in others); face distinctly longer than wide, eyes not convergent below tan, weak rim; eye-eye line shorter than postocellar line, diameter of lateral eye equal to the latter; templesflat; mesonotum strongly polished, glabrous, posteriorly not weak; propodeum with deep longitudinal furrow in basal middle but without carina; first tergite much longer than broad apex, its sides almost straight and divergent, its collar obsolete beyond apex, not flattened dorsally; lateral tubercles strong ontergites 2-6, apical impressions broad and interrupted at middle, extended part of sheath very slightly curved and very sharp apex, about half as long as abdomen; wings with transverse cubitus two-thirds as long as second abscissa of cubitus, not far below middle nervule distinctly broken; hind basitarsus barely as long as next two joints together. Black; scutellum, postscutellum and spots on base of middle and hind legs piquant; apical part of clypeus and mandible brown; palpi white; antennae blackish, slightly paler below at the base, especially at the apex of the shell; wing bases, tegulae, and posterior angle of pronotum wliite; legs testaceous with the following pattern; fore coxae apically, fore trochanters, femora apically, apical segments of hind and middle trochanters and their basal joints at apex, all tibiae above, fore tarsi, hind and middle tarsi above vs.

31 Smooth head, face with dense and short eyebrows; malar groove present, as long as basal width of mandible; clypeal suture weak; .. strongly convex temples; apex of view barelyoblique, pedicelaly as long as stage; prothorax smooth, thorax otherwise subdued, darkly punctate and, especially above, pubescent; mesoscutura nearly as wide as long, prescutuni short and broad; propodeum with a median long dorsal and a more or less distinctly separated caudal area, the areas smooth; first much longer than wide, . its sides straight and divergent, carinae effaced just behind tip of tergite, longitudinally rugulose; tergites 2 to 4 with median areas smooth or obscurely rugulose transversely, the second nearly twice as long; intercubitus very short; nervellus straight, perpendicular; hind tarsi stout, much shorter than tibia, basal joint about elongate near two together. The National Collection contains two female specimens, one from Chiric Mountains, Arizona, H. Hubbard; and the other from Colorado, Baker. However, the following characteristics may be noted: malar}?acen long to basal width of jaw; longitudinal raised face; convex temples, with a large slope; propodeum with well-defined median areas; rhomboid areas of tergites distinctly open, torn, impressions striated, apices smooth; thin legs; intercubitus short but distinct; the nerve is not broken.
Differs from other idii Hoeward in the indistinctly defined rhomboidal areas of the tergites; with the front and middle legs paler; the tips of their small tibiae and hind body brown; and the hind tibia with subbasal black annulus. Type.—Acad.Nat.Sci.Phila. Head polished, temples rounded, eyes converging slightly towards the mouth, barely rimmed; face slightly longer than wide; malar space about half as long as basal width of mandible; postosella and axillary-ocular lines across a qualand somewhat larger than the diameter of the lateral ocellus; .. mesoscutum but a little longer than wide, the prescutum in front of notauli about one quarter of the total length of mesoscutum; median carinae of propodeum ])recent, the apical carina obscurely defined;. Mainly differs from the female color, the dark color of the body is more prone to spicy, and its color is less colored and more of the fuscous, the legs and mouth paler, sheep and pedicel white, scutellum whitish; the tergites are proportionally narrower and the impressions less distinct; hind tarsi about equal in length to tibiae.
The type is from Illinois, the homotype from Indiana, and the female from Washington, District of Columbia. Allied to nigrocepJiala (Davis), from which it differs in addition to the characters used in the keys as follows: prescutum before notauli narrow, about one-third total length of mesoscutum; first tergite nearly}^ as wide at apex as long, not angular at spiracles, dorsal carinae rather strong; apical furrows of tergites weak, interrupted medially, rhomboidal areas rather poorly defined.

One female with the number of the Bureau of Entomology no. 23502, which refers to a note in the Bureau's files recording that the specimen was bred, but from what is not known. Color pattern same as in californiensis, but darker throughout, metasternumasSvellasprosternum inmesosternum black, all coxae and femoratestaceous, those on fore and middle legs somewhat paler, tibiae with usual rings, testaceous in middle and fuscous on hindtibiae; pale abdominal bands narrower. Head very broad in front, eyes large and prominent, strongly convergent within; oral region convex; malar space almost as long as basal width of mandible; temples rather strongly convex; head polished.
Thorax Polished; notaulistrong, prescutum long; propodeum shagreened, weakly, shortly canaliculate medially at base, noncarinate; legs long, slender, hind tarsus nearly as long astibia; stigma broad with radius in middle; intercubitusveryshort;.
SPECIES WRONGLY PLACED IN GENUS AND UNRECOGNIZABLE SPECIES
Thorax polished; notaulistrong, prescutum long; propodeum shagreened, weakly, shortly canaliculate medially at base, uncarinated; legs long, slender, hind tarsus almost as long as astibium; stigma broad with a radius in the middle; intercubitus very short;. rather thin, shagreen, polished apically and on apical areas of tergites, median areas distinct on tergites 2-4, faint on 5; first tergite much longer than wide, sides rather strongly diverging, spirals rather distinct; second tergite about as long as wide at apex. face and clypeus piceous; thorax testaceous; pronotum and propo-. deumpiceous; tegula and humeral corners of pronotum white; fore and middle coxae and all trochanters stramineous; hind tibia white with small basal and large apical annulifuscous, their tarsifuscous except for pale annulus on baseofbasitarsus; legs otherwise different shades of testacea; ventral, apices of tergites dark and base of soft tergites tending to yellow. The nearest relative of the Theronini among these tribes is probably the E])hialtini, and from this tribe it is easily distinguished by the shape of the ovi])ositor, the slotted propodeal spiracles with their conspicuous enclosing carinae, the short, deep, parallel notaule, and the polished, usually light- colored body . 39. apex strongly oblique, pedicel about as long as shell, basal joint of offlagellum nearly twice as long as second, that above middle as wide as long; thorax rather short, above above; notauli short and parallel, deep anteriorly with ridge running backward along margin of lateral lobe; prepectus wide, carina turning sharply towards promesothoracic suture about halfway through pleura; .. mesopleural suture angular opposite punctiform fovea; .. shield strongly convex, emarginate only at the base; propodeum with at least very strong apex carina, corolla long and slit-like, surrounding carina high; wings large, stigma narrowly lanceolate, radius before middle, areolata broadly sessile, nerves strongly emarginate and broken far above middle; legs, especially hind femora, strong, hind tarsal joint on hind legs as long as first; abdomen .. fusiform, rather narrow at base; first tergite longer than wide and longer than second, second transverse, apical tergite short; ovary shorter than abdomen, subcylindrical, lanceolate almost flat dorsally at apex; hypopygidium retracted.
These are the only characters of any importance that I have discovered; and of these only two, the proposal carinae and the infumation of the wing apices, there are no exceptions within any of the genera represented in the material examined. As indicated above, the difference between this and the other genera of the Theroniini is relatively small and largely a matter of difference in the degree of development of certain characters. Krieger's variety americana of the European atalantae (Poda), based on a specimen from British Columbia, is undoubtedly this species; and a male labeled by Viereck with the name of Kj-ieger is a normal male of this species.
The present species is perhaps nothing more than a geographical race of atalantae, but judging from a comparison of the material. The sculpture of the face varies somewhat in the series examined, and several specimens, including one from the same locality as Viereck's type, have many.

Living as a primary parasite of pupae of lepidoptera it would necessarily be internal; and the writer believes that in those cases where Fiske and Thompson believed it to be primary, the rest of the true primary was simply not found. In terms of colour, this species is somewhat less variable than ice fulvescence, but the variation in size is practically the same, the females examined measuring from 7 to 13 mm. and males from 7 to 12 mm in length. The National Museum's series includes specimens from Massachu-. setts, New York, Indiana, WestVirginia, Maryland and Virginia, while Provancher had from Canada.
There are no biological records associated with any of the specimens examined, but it was recorded to have been reared from Porthetria d%s])ar (Linnaeus), Malacosomaamericana (Fabricius) and Halisidota maculataHarris, and in another case it was associated with (Pimpla ) EpUaltes pedalis (Cresson). ). The Ashmead species is very likely. a synonym of mikane, but the tips of both forewings of the only specimen are missing, and it is not possible to say whether it had a darker spot at the apex of the radial cell. In the United States National Museum, including Yiereck's two types, there are ten specimens, four females and six males, which are undoubtedly identical. it is not as described by Viereck, but is perfectly normal for the genus, the pale being entirely at the tip of the wing with a darker spot covering the apex of the radial and the upper outer angle of the third cubital cell.
Krieger, by inference only, says that his species lacks the dark band on the first tergite; winnamanae hasit, but in the series of specimens it varies from wide and distinct to almost absent. In addition to the type females, the NationalCollection contains another female from the type locality, Plummers Island, Maryland, September 29, 1912, P.R. Smith, threeat Pyziton, ClayCounty, and the other at Coleta; one wife, TaUulah, Louisiana, V. Safro; and one male without it.
