MALE — Length 7.5-8 mm.; bluish-green, but face, vertex and dorsum of thorax somewhat more olive-green, legs black; face slightly longer than distance between eyes above; eyes slightly convergent below; lateral ocelli sub- equally distant from eyes and each other, much nearer margin of vertex; clypeus convex, somewhat produced apically, the broad apical margin nearly straight, very narrowly shining and impunctate; median length of labrum slightly less than basal width; mandibles bidentate; cheeks very slightly broader than eyes; wings subhyaline, becoming very faintly infuscated toward apical margin, 2nd recurrent vein reaching 2nd submarginal cell considerably nearer apex than 1st does to base; tarsal segments slender and simple, anterior margin of hind basitarsus with a very low and inconspicuous tubercle near apical third, mid and hind spurs piceous; pubescence entirely pale, largely yellowish-white on face and dorsum of thorax, otherwise more whitish, copious and elongate on face and clypeus, cheeks below, on basal abdominal tergum and over most of thorax; discs of abdominal terga 2-5 with short, erect but quite copious, yellowish pubescence which does not hide the surface; punctures in general deep and distinct, rather coarse and close but not crowded on vertex, becoming somewhat closer but more shallow on cheeks, quite densely crowded below ocelli, very fine and densely crowded on clypeus beneath pubescence; punctures quite uniformly coarse and close on scutum, being very slightly separated only in center of disc, those of scutellum close but not crowded, becoming fine and obscure around posterior margin; pleura dull, punctures rather shallow but largely contiguous, with a restricted area beneath tegulae which is more shining and sparsely punctate; lateral faces of propodeum somewhat shining and shallowly, obscurely punctate along anterior margin, becoming smoother but dull posteriorly, posterior face more tessellate, with shallow, obscure, scattered punctures, dorsal area smooth but velvety, becoming rather broadly sub- striate along upper margin; abdominal terga shining, punctures quite deep and distinct but rather fine, rather uniformly close but not crowded, quite evenly distributed to the rather broad, depressed and entirely impunctate, apical margins; punctures of tergum 6 much finer and more sparse in general, apical margin with a shallow median, emargination, 7 rather broadly produced apically, with a semicircular, median emargination; sternum 2 broadly out- curved apically, largely covering 3 and base of 4, apical margin of 3 with a rather large, triangular, median emargination which is largely filled with elongate, convergent setae (fig. 33), 4 rather broadly produced apically, median area quite straight, surface rather uniformly, finely setose across entire plate; sterna 5-8 entirely retracted, submembraneous; genital armature as shown (fig. 35).
