MALE—Length 8 mm.; entire body brilliant blue, green or purple; mandibles and labrum black to piceous; clypeus somewhat shining above, punctures shallow but coarse and close over most of disc; supraclypeal area shining and nearly impunctate over lower half, upper half somewhat roughened; face above antennae densely and rather finely rugosopunctate; cheeks below shining, with only a few scattered, minute and obscure punctures, becoming minutely and very closely punctate or tessellate above; antennae entirely dark, very short, segments of flagellum hardly longer than broad; pubescence of head and thorax pale ochraceous, tinged with fuscous dorsally, becoming white laterally and below; scutum with distinct but close and rather deep punctures medially, becoming densely and finely rugoso-punctate laterally; scutellum somewhat shining between the scattered but rather coarse and close punctures; pleura closely and rather coarsely and deeply punctate, becoming more rugose or reticulate anteriorly; dorsal area of propodeum very much shorter than metanotum, smooth and shining, lateral faces shining, finely and rather closely and shallowly punctate, posterior face rather dull, coarsely rugoso-punctate; tegulae narrowly green or blue along inner side, outer margin becoming testaceous-hyaline; wings lightly infuscated, veins and stigma testaceous; all tarsi yellowish, legs otherwise green; abdominal terga smooth and shining, with very fine but deep and distinct, evenly distributed and rather close punctures, without apical fimbriae, apical margins only slightly impressed, with punctures not greatly different from the discs; basal tergum entirely pale pubescent, the light pubescence of discs of the following terga more or less intermixed with subappressed fuscous hairs; sterna 1-3 metallic, the following sterna piceous, 4 often hidden by 3, apical margin broadly incurved, with a very small median acute projection, 6 with a very slight median incision; ventral inner lobe at base of gonostyli triangularly acute, the subapical dorsal lobe broad and expansive, acute apically, covering tips of penis valves, apex of gonostyli slightly excavated, bearing numerous rather short setae; volsellae obscure; penis valves deeply excavated dorsally toward base.
