FEMALE—Length 7 mm.; black; pubescence very thin, largely pale, but more or less fuscous on front of head; head slightly longer than broad; eyes subparallel; clypeus much broader than long, strongly protuberant; Labrum much broader than long, largely exposed by the closed mandibles, these with an inner subapical tooth; cheeks above somewhat narrower than eyes, becoming very narrow below; lateral ocelli subequally distant from eyes and each other; antennae subequally distant from eyes and each other, separated from upper margin of clypeus by a space no greater than diameter of the fossa, segments of flagellum not much longer than broad; face just below ocelli very finely and closely punctate, but surface shining, becoming sparsely punctate above and to each side of antennae, supraclypeal area shining, strongly protuberant, with close, deep and fine punctures, those on clypeus considerably coarser and rather sparse; punctures of vertex close, but considerably deeper and more distinct than those below ocelli, becoming minute, rather vague and obscure on upper part of cheeks, lower part smooth, shining and almost impunctate; scutum and scutellum shining, punctures minute in large part, well separated but not sparse over most of scutum, rather close but still definitely separated between notaulices and tegulae, those on scutellum well separated, rather variable, surface smooth and quite flat; pleura smooth and shining, with minute, well separated but hardly sparse punctures; dorsal area of propodeum very finely and closely rugosostriate, width about equal to that of scutellum, lateral and posterior faces smooth but rather dull, punctures indefinite; tegulae brownish-hyaline posteriorly, becoming more or less fuscous anteriorly; wings subhyaline, slightly darker apically, veins and stigma ferruginous; 2nd recurrent vein entering 2nd submarginal cell considerably nearer its tip than 1st is to base; legs entirely blackish to ferruginous; the more basal abdominal terga smooth and shining, with exceedingly minute, well separated and obscure punctures, tergum 2 somewhat more definitely but still minutely punctate, 3rd and 5th more or less tessellate, with fine, well separated punctures; apical margins of terga 1-5 with well defined, impressed, apical areas, these bare, more or less yellowish-hyaline, discal pubescence very short, entirely pale, becoming more dense and elongate only at tip of abdomen.

MALE—Length 6-7 mm.; black; head considerably longer than broad; eyes very short, very slightly convergent below; clypeus strongly protuberant, much broader than long; cheeks narrower than eyes and much narrowed below; lateral ocelli somewhat nearer margin of vertex than to each other, subequally distant from eyes and each other; antennae slightly nearer eyes than to each other, separated from upper margin of clypeus by a space somewhat greater than diameter of fossa; face shining, punctures deep and distinct, fine and close near center below ocelli, becoming more sparse on each side below, supraclypeal area quite strongly convex, densely pubescent, punctures beneath fine and quite close, those on clypeus more coarse, quite close above, becoming shallow and indefinite toward apical margin; vertex shining, punctures minute and well separated medially back of ocelli, becoming deeper, more distinct and close laterally, cheeks shining, minutely punctate above, becoming largely impunctate below laterad of hypostomal carinae; scutum and scutellum shining, punctures minute and well separated, somewhat variable in size and distribution; pleura shining, very minutely and quite sparsely punctate; dorsal area of propodeum finely rugosostriate, about as broad as scutellum, hind margin quite definite, lateral and posterior faces rather smooth but dull, punctures indefinite or absent; tegulae dull testaceous-hyaline; wings lightly infuscated, veins and stigma brownish-testaceous; legs dark, hind pair quite slender and unmodified; abdominal terga smooth and shining, punctures on basal terga minute, well separated basally, becoming largely absent toward apical margin, those on the following terga more distinct, relatively close toward base of each, becoming very sparse toward apical margin, impressed apical rims entirely impunctate, somewhat reddened, discal pubescence extremely short and obscure, more conspicuous laterally, entirely pale except on the more apical terga where there are some suberect, fuscous hairs; sterna 1-4 simple and unmodified, apical margin of 5 rather broadly incurved, 6 with a pair of rather elongate, oblique, subapical carinae and a short, median, apical process; sterna 7-8 as shown (fig. 128); gonostylus of genital armature slender, elongate, acutely pointed apically, tips of penis valves with a recurved, subapical barb, cuspis of volsella slender and elongate, but not markedly pubescent.

DISTRIBUTION—Wisconsin and Tennessee; July and August.
