FEMALE—Length 10 mm.; dark bluish, becoming almost black in some areas; face considerably longer than distance between eyes above; eyes somewhat convergent below; lateral ocelli subequally distant from each other and margin of vertex, very slightly more distant from eyes; clypeus convex but strongly produced apically, median area of margin nearly straight, very narrowly polished and impunctate; labrum short, not much more than half as long as basal width; mandibles much broadened apically, dentition much as in albiventris (fig. 32); cheeks considerably broader than eyes; wings very lightly infuscated, becoming somewhat darker apically, 2nd recurrent vein reaching 2nd submarginal cell much nearer apex than 1st does to base; front basitarsi somewhat flattened, posterior surface somewhat concave, fringed with elongate, white hairs; mid and hind spurs piceous; pubescence of head and thorax largely yellowish-white, but clypeus with a subapical, rather dense brush of fuscous hairs; pubescence quite long and copious over most of thorax, elongate and white on basal abdominal tergum, discal pubescence of the following terga erect, entirely white, rather thin and inconspicuous, that on tergum 6 subappressed and silvery, scopa entirely yellowish-white; punctures deep and distinct in general, rather well separated but not sparse on vertex, becoming quite close but not crowded below ocelli and along sides of face, close, deep and distinct on clypeus, but this with a median, triangular, shining and impunctate area on upper margin; scutum and scutellum shining, punctures close but not crowded, becoming rather sparse in center of scutum and in midline of scutellum, pleura rather dull, with densely crowded, shallow punctures, lateral faces of propodeum somewhat smoother but finely roughened, posterior face dull, more tessellate, dorsal area velvety, becoming very finely and obscurely substriate along upper margin; abdominal terga shining, punctures fine but rather close and deep, becoming somewhat closer at extreme sides, apical margins rather narrowly depressed but well punctured nearly to the rims, tergum 6 very finely and densely punctate.


MALE — Length 9-10 mm.; bluish-green, with dorsum of head and thorax somewhat more olive-green; face somewhat longer than distance between eyes above; eyes slightly convergent below; lateral ocelli subequally distance from eyes and each other, slightly nearer margin of vertex; clypeus convex, apical margin somewhat produced, median area nearly straight, narrowly polished and impunctate; median length of labrum about equal to its basal width; mandibles bidentate; cheeks slightly broader than eyes; wings subhyaline basally, becoming very faintly infuscated toward apical margin, 2nd recurrent vein reaching 2nd submarginal cell much nearer apex than 1st does to base; tarsal segments simple and unmodified, anterior margin of hind basitarsus without a definite tubercle, mid and hind spurs piceous; pubescence of head and thorax yellowish-white, quite copious over face and cheeks and over most of thorax, basal abdominal tergum with copious, more whitish pubescence, discal pubescence of following terga very short and inconspicuous but erect and evident; punctures rather deep and distinct, rather fine and close in general, close but not crowded on vertex and dorsum of thorax, becoming densely crowded on face below, on cheeks and on pleura, lateral faces of propodeum smooth but rather dull, minutely and closely punctate, posterior face more tessellate, punctures close but obscure, dorsal area velvety, becoming very narrowly and irregularly striate along upper margin; abdominal terga smooth and shining, punctures fine and quite close, but not crowded, apical margins rather narrowly depressed, these areas invaded in part by very fine and scattered punctures, only the narrow rims impunctate; tergum 6 rather sparsely punctate and shining, with a small, median, apical emargination, 7 quite broad, rather broadly produced medially, with a deep, narrow, median emargination; sternum 2 broadly outcurved apically, largely covering 3 and base of 4, 3 with a deep, triangular, median emargination which is fringed with short setae which do not converge medially (fig. 33); sternum 4 rather broadly produced apically, this area quite strongly incurved and slightly thickened (fig. 34); 5-8 entirely retracted, submembraneous, apical margin of 8 somewhat narrowly rounded apically; genital armature as shown (fig. 35).
