FEMALE—Length 6.5-8 mm.; entirely black; face slightly longer than distance between eyes above; eyes very slightly convergent below; lateral ocelli subequally distant from eyes and each other, slightly nearer margin of vertex; clypeus very slightly convex, apical margin somewhat produced, practically straight, mandibles only slightly broadened apically, distinctly tn-dentate, median tooth only slightly nearer apex than to inner angle; cheeks slightly broader than eyes; wings subhyaline basally, becoming faintly infuscated apically, stigma brownish-piceous, veins more brownish-testaceous; tegulae shining, piceous, with punctures hardly evident; legs entirely black, spurs pale yellow; pubescence entirely pale, rather short and thin, but quite copious around antennae, on face below, and over much of thorax, the dorsal pubescence elongate but very thin; abdominal terga 1-4 with narrow, whitish, apical fasciae, these widely interrupted medially on 1 and 2, usually entire on 3 and 4, 5 not fasciate, discal pubescence exceedingly short and inconspicuous, hardly visible on the more basal terga, but becoming quite dense and subappressed on tergum 6, apical margin of 6 very slightly reflexed and shelf-like; scopa entirely yellowish-white; punctures quite deep and distinct, rather coarse and close and somewhat finer on most of face, including vertex, becoming densely crowded on clypeus, close and fine on cheeks, but lower surface shining and impunctate, the two areas separated by a row of long, curled, whitish hairs directed toward the hypostome; scutum and scutellum shining between deep and distinct but quite close punctures, these almost crowded on pleura, the propodeum dull and tessellate, punctures very shallow and indefinite; abdominal terga shining, punctures fine and slightly separated on basal tergum, well separated medially on 2 and 3, uniformly close and fine on 4-6.


MALE—Length 6 mm.; entirely black; face considerably longer than distance between eyes above; eyes very slightly convergent below; antennal scape slender and rather short, not much if any exceeding diameter of flagellum, pedicel completely exposed, flagellar segments slender and simple, considerably longer than broad; lateral ocelli subequally distant from eyes and each other, somewhat nearer margin of vertex; clypeus slightly convex, apical margin slightly produced, nearly straight, disc covered with relatively elongate, more or less erect, whitish pubescence; labrum shining, rather flat and unmodified, median length somewhat less than basal width; mandibles bi-dentate; cheeks subequal in width to eyes; wings subhyaline, veins and stigma brownish-testaceous; tegulae shining, brownish-testaceous, with minute, scattered punctures; legs entirely black, spurs pale yellow; tergum 7 exposed apically, margin rather broadly rounded, with a slight, subapical impression; sterna 1-5 exposed, apical margin of 2 somewhat outcurved, the disc rather expansive, 3-5 more nearly straight apically, 6-8 retracted, form as shown (fig. 25); genital armature as shown; pubescence entirely pale, rather thin in general, somewhat more copious over head and thorax, rather dense over lower half of face and on cheeks below, abdominal terga 1-5 only vaguely white fasciate apically, and then only at sides; punctures rather fine but deep and distinct over most of head and thorax, densely crowded over most of face, quite close on vertex and cheeks, becoming somewhat more shallow on cheeks below, lower surface shining and more minutely punctate and more densely pubescent; scutum and scutellum shining, punctures slightly separated in center of discs, otherwise rather close, quite close over most of pleura, becoming rather sparse on a limited area just beneath wing base; lateral faces of propodeum dull and tessellate, without distinct punctures, posterior face also quite dull, relatively impunctate, without a distinct striate area beneath metanotum; abdominal terga 1-5 shining, punctures very fine and well separated medially, becoming somewhat closer on the more apical terga, rather close at sides even on basal tergum, 6 rather closely but irregularly punctate.
