MALE—Length 5 mm.; head and thorax green, abdomen reddish-piceous, maculations bright yellow; face considerably longer than distance between eyes; eyes subparallel; cheeks very slightly narrower than eyes; vertex rather broad, but hind margin indefinite, lateral ocelli subequally distant from eyes and each other; foveae very small but deep and distinct; mandibles, labrum and clypeus bright yellow, mandibles becoming ferruginous apically; facial maculae large and conspicuous, filling area between lower portion of clypeus and eyes, extending up margin of eye to level of antennae, where they terminate obliquely; scape yellow anteriorly, flagellum yellowish testaceous beneath, more brownish-piceous above; face below antennae quite smooth but without evident punctures, area above antennae densely tessellate, dull and impunctate, cheeks more shining, with minute and rather close punctures; pubescence of head and thorax very short, rather thin and entirely white; thorax entirely green, without maculations; scutum and scutellum densely tessellate, punctures exceedingly minute and obscure, hardly visible; pleura more shining, with a few scattered, minute and vague punctures, propodeum rather smooth, finely tessellate and impunctate; tegulae testaceous-hyaline; wings subhyaline, veins and stigma pale testaceous, stigma margined with brown; coxae and trochanters yellow, but hind coxae with dark, basal areas, femora piceous over most of length, but with yellow base and apex, front pair yellow anteriorly; front and mid tibiae yellow anteriorly, piceous posteriorly, hind tibiae and tarsi entirely dark, front and mid tarsi entirely yellow; abdominal terga 1-5 with transverse, sub basal, narrow maculae, those rather widely separated along mid line, the pair on 5th tergum quite small; discs of terga quite smooth, the more basal plates impunctate, but with exceedingly minute and rather sparse punctures becoming evident on the more apical segments, apical rims very narrowly depressed; apical margin of sternum 6 rather narrowly and deeply emarginate medially; sterna 7 and 8 much as in polygonellae (fig- 00); gonocoxites of genital armature somewhat bulbous, narrowly truncate apically, gonostyli rather slender apically, but the base compressed, about attaining tip of penis valves which are slender apically, broadly dilated toward base where they are angulate laterally, volsellae with distinct, somewhat compressed cuspis and slightly shorter digitus.
