MALE—Length 10-13 mm.; length of face exceeding its greatest width: eyes slightly convergent below; length and breadth of malar space subequal; antennae dark, median segments fully twice as long as broad; clypeus closely, deeply and rather coarsely punctate beneath the dense pubescence; pubescence entirely pale on head and thorax, more or less fulvous on dorsum of thorax; prothoracic spines not evident; metapleural protuberance low, very inconspicuously carinate, if at all; tegulae yellowish-ferruginous; wings lightly infuscated, veins and stigma pale ferruginous; scutum shining, punctures coarse and deep, close laterally, slightly less so medially; those on scutellum slightly more coarse, rather close except along anterior border; pleura dull, punctures close, coarse and deep; dorsal area of propodeum short, shining, the parallel striae forming a series of narrow pits: tarsi dark, basitarsi slender, spur yellowish-ferruginous; abdominal terga smooth and shining, punctures deep and distinct, well separated and rather fine on the more basal segments, becoming close and minute on the more apical segments, apical margin of segments only very slightly depressed, more or less reddish-hyaline, with rather incomplete or thin, white, apical fasciae, discal pubescence dark, but short and very inconspicuous.
