II, 228. Male. Eyes contiguous, the small frontal triangle grey; epistoma light grey. Occiput grey, with black hairs. Labruni as long as, or slightly longer than the head is high, ferruginous or brown. Antennae about as long as the head, blackish, the two basal joints yellow, with short, brownish hairs, the third joint somewhat elongated and attenuated towards the apex. Thorax dull grey, with three narrow brown stripes, the lateral slightly abbreviated in front, the median behind, the two interstices between the stripes slightly darker grey; the humeri with a yellow point. The dorsocentral and acrostichal bristles short, but somewhat strong, black; the former uniserial, the latter biserial; the hinder dorsocentral bristles long and also the foremost somewhat long. Further a humeral bristle, a posthumeral, a notopleural, a supraalar and a postalar bristle, all black; besides there are only a few short hairs. Scutellum with four black marginal bristles, the two median strong. Pleura light grey, metapleura with blackish hairs.
