FEMALE—Length 13 mm.; black, with yellow maculations; clypeus, a spot on outer face of mandibles, lateral face marks extending very narrowly nearly to top of eye, an elongate stripe on cheeks just back of eye, and an oblong spot on each side of vertex, yellow; lateral margins of scutum, a spot on axillae, and posterior margin of scutellum, yellow; tubercles with a very small yellow spot and outer anterior third of tegulae yellow; pleura with a small, anterior, yellow spot; legs dark basally, more or less reddish, becoming more ferruginous apically, but lower posterior margin of front and mid femora narrowly yellow, a yellow stripe from base to near the tip on outer face of front tibiae, mid tibiae with a basal yellow spot and hind tibiae yellow along posterior margin from base to apex, hind basitarsi yellow in part; spurs testaceous; terga 1-5 with entire, transverse, yellow bands, these very narrow medially and with a rather conspicuous, anterior emargination toward each side; apical rims of terga slightly depressed and entirely black; tergum 6 with a broadly V-shaped, median, yellow mark; face considerably longer than distance between eyes; eyes nearly parallel; lateral ocelli widely removed from posterior margin of vertex and somewhat nearer eyes than to each other; cheeks subequal to eyes in width; mandibles broadened apically, teeth barely evident; clypeus slightly convex, apical margin straight but minutely denticulate; tegulae very finely and closely punctate; wings lightly infuscated, somewhat more deeply so apically and in region of marginal cell, veins piceous; pubescence entirely pale, thin and quite short, very inconspicuous on upper portion of head, thorax and abdominal terga, more dense and conspicuous on thorax laterally and posteriorly, ventral scopa entirely yellowish-white; punctures rather deep but quite close and rather fine in general, slightly separated just below ocelli, and cheeks shining with minute and rather sparse punctures posteriorly, becoming closer toward eyes; pleura very finely and closely punctate, scutum and scutellum somewhat more coarsely but densely rugoso-punctate; abdominal terga somewhat shining, but punctures fine and uniformly close, those tergum 6 minute and densely crowded.
MALE—Length 14 mm.; black, with yellow maculations; clypeus, mandibles except the teeth, lateral facial maculae terminating very narrowly on eye just above antennae, a small spot on each side of vertex, and a narrow mark extending from upper third of eye to inferior limit of cheeks, yellow; tubercles with a very minute yellow spot laterally, scutum narrowly margined with yellow on each side and tegulae in large part yellow; coxae and trochanters largely black, femora and tibiae black in part, ferruginous beneath, tibiae yellow at base and apex, these two marks more or less connected by a narrow, yellow band, front femora yellow on lower margin, hind femora with a small yellow apical spot, all basitarsi yellow, the other tarsal segments becoming more reddish; abdominal terga with entire, narrow, transverse, subapical, yellow bands, the depressed margins narrowly black, bands abruptly broadened at each side, but quite narrow across the central expanse of each disc; tergum 6 largely yellow apically, black across base, the yellow area triangularly invaded with black on basal margin; face much longer than distance between eyes; eyes subparallel; lateral ocelli widely removed from margin of vertex, considerably nearer eyes than to each other; cheeks very slightly broader than eyes; mandibles 3-dentate; clypeus slightly convex, apical margin minutely denticulate; tegulae finely and quite closely punctate; wings faintly infuscated, veins piceous; all basitarsi rather slender and elongate; pubescence entirely pale, quite thin but rather elongate above except on the more apical abdominal terga, dense around antennae, on cheeks below and on pleura and venter of thorax, entirely whitish on legs and venter of abdomen; punctures quite deep and distinct, rather close in general, minute and rather sparse on cheeks posteriorly, but becoming quite close and coarse on vertex and on face below; punctures fine and quite close on pleura, the scutum and scutellum rather coarsely rugoso-punctate; punctures close on abdominal terga, rather coarse on basal tergum but rather fine and uniform on 2-5, 6 rather densely rugoso-punctate; tergum 7 rather coarsely rugoso-punctate, apical margin rather narrowly produced medially, this area obscurely tn-dentate; sterna 1-4 exposed, ferruginous, more or less pubescent, sternum 3 with a pair of short, dark, slender and distinct spines; sterna 5-8 retracted, form as shown (fig. 9); gonostyli of genital armature rather broadly dilated and angulate apically, as shown (fig. 10).
