MALE—Length 13 mm.; bluish-green, the vertex, upper half of face and dorsum of thorax somewhat brassy, legs black; face muchlonger than distance between eyes above; eyes very slightly convergent below; lateral ocelli subequally distant from eyes, margin of vertex and each other; clypeus slightly convex, apical margin considerably produced, nearly straight; median length of labrum considerably less than basal width; mandible bidentate, inner tooth broadly truncate; cheeks considerably broader than eyes; wings subhyaline, 2nd recurrent vein reaching 2nd submarginal cell about half the distance from apex as 1st does to base; tarsal segments unmodified, anterior margin of hind basitarsus not toothed; front spurs testaceous-hyaline, mid and hind spurs black; pubescence elongate, whitish on face, pleura and terga 1 and 2, more yellowish on vertex and dorsum of thorax, black on cheeks, mid and hind legs, and terga 3-6; punctures fine and densely crowded over mostof head and thorax lateral faces of propodeum somewhat smoother, punctures fine and rather shallow, posterior face dull and tessellate, punctures becoming inevident medially, propodeal triangle dull and tessellate but rather smooth; punctures of abdominal terga somewhat finer, more distinctly separated medially on 1-5, becoming slightly closer toward extreme sides, apical margins quite broadly shining and impunctate; apical margin of tergum 6 nearly straight, without a median emargination, 7 broadly subtruncate, with a shallow median emargination; sternum 2 slightly outcurved apically, with a small, shallow, median emargination, not hiding margins of 8 and 4, 3 with a quite deep, median emarginate area which is conspicuously fringed, but the setae short, not meeting at midline; apical margin of sternum 4 broadly rounded, not at all thickened, margin of 5 nearly straight, 6-8 (fig. 26) retracted, lateral portions of 7 quite heavily sclerotized and setose; genital armature as shown.

DISTRIBUTION — British Columbia to New Mexico, east to Michigan, April to June. This is the first record of integra in the East, and is based on the following: 2 ♀♀, Chippewa Co., Mich., June 7, 1959 (Dreisbach).
