FEMALE—Length 5 mm.; black; face slightly longer than distance between eyes above; eyes subparallel; cheeks subequal to eyes in width; process of labrum about half as long as the basal width, very broadly rounded apically; facial foveae very shallow and obscure, narrow and elongate, terminated below about at level of antennae; space between margin of vertex and lateral ocelli only slightly exceeding their diameter; apical two- thirds of flagellum ferruginous, median segments slightly broader than long; face above antennae rather dull, punctures minute and obscure, well separated but hardly sparse, becoming slightly more distinct on shining cheeks, area below antennae more shining, punctures somewhat more coarse but quite regularly sparse; pubescence of head and thorax short, entirely pale, rather copious but not hiding surface; tubercles black; tegulae testaceous-hyaline; wings subhyaline, veins brownish to testaceous; 2nd recurrent vein entering 2nd submarginal cell about one- fourth from apex; the more apical tarsal segments somewhat reddened, legs otherwise dark, spurs yellow; dorsum of thorax rather dull, punctures very fine, rather shallow, well separated but hardly sparse, scutellum somewhat more shining; pleura quite dull, finely tessellate, punctures shallow, obscure and very sparse; apical margins of abdominal terga rather narrowly depressed, these areas slightly reddened, finely pebbled, discs of the terga finely pebbled, punctures minute and indistinct, well separated on median segments, very sparse and obscure on basal segment; abdominal pubescence very short, thin and sparse, entirely pale, forming a rather dense, apical, brownish fimbria on tergum 5.

MALE—Length 5 mm.; black; face very slightly longer than distance between eyes above; eyes somewhat convergent below; clypeus entirely yellow, face otherwise black, including lab rum and mandibles; cheeks slightly narrower than eyes; process of labrum slightly broader than long, apical margin broadly rounded or subtruncate; facial foveae very shallow and obscure, narrow and somewhat elongate; space between margin of vertex and lateral ocelli subequal to their diameter; flagellum testaceous beneath, median segments about as broad as long; face above antennae rather dull, punctures very minute and obscure, rather close, becoming somewhat more distinct and sparse on vertex laterally, close and rather deep on the shining cheeks, very minute and obscure on supraclypeal area, the surface rather dull, becoming more deep and distinct on the lateral portions of face below antennae, punctures of clypeus rather coarse, well separated, but obscure; pubescence of head and thorax rather short but quite dense, obscuring but not hiding surface, entirely pale; tubercles dark; tegulae reddened; wings subhyaline, veins and stigma brownish to testaceous; 2nd recurrent vein entering 2nd submarginal cell about one-fourth from apex; tarsi and spurs yellow, front tibiae yellow anteriorly, otherwise dark, mid and hind tibiae dark except for a very small and obscure basal yellow spot; surface of thorax rather dull, punctures of scutum fine and obscure, rather close anteriorly, becoming more sparse posteriorly, those on scutellum somewhat deeper and more distinct, quite close; pleura tessellate and almost impunctate; apical margins of abdominal terga rather narrowly depressed, these areas slightly reddened, finely pebbled, discs of the terga minutely and obscurely pebbled, somewhat shining, punctures very minute and well separated but hardly sparse; abdominal pubescence very short, thin and obscure, entirely pale; sternum 6 rather strongly narrowed apically, the restricted apical margin with a rather deep, triangular, median emargination; sternum 7 narrowed apically, the apex produced medially into a pair of elongate, flattened processes, separated by a deep, median emargination; apical process of sternum 8 rather short, somewhat expanded apically, the apex sub- truncate, basal portion somewhat expanded; gonostyli very small, slender and simple; penis valves slender, slightly more robust, fringed beneath toward base.
