black in ground color, brownish gray pollinose on the dor- 
sum gray on the sides. Humeri yellowish brown. Tegulse 
and halteres yellow. Propleura each with a fan of hairs, 
dorsocentral and marginal scutellar hairs small and incon- 
spicuous. Metanotum evenly convex, without a transverse 
furrow. Legs : Chiefly yellow, coxae and apical subseg- 
ments of tarsi brown, femora with slight discolorations 
of brown in the middle. Hind trochanters with a dense 
patch of short yellow pile beneath. Middle coxae with 
several long curved hairs at their apices above. Femora 
rather slender, flexor spines well developed, these are 
short and black on the middle and hind pairs and long, 
yellow and bristle like on the first pair. Tibiae without 
strong erect bristles medianly. Tarsal claws and pulvilli 
very small, shorter than the last subsegment of the tarsus. 
Wings: Very lightly fumose, stigma pale brown and 
filling all of the third costal section. Crossvein r-m 
situated at about the basal three-sevenths of the discal cell. 
Last section of the fourth vein very gently curved, almost 
straight. Ultimate section of the fifth vein slightly 
shorter than the m crossvein. Abdomen: Chiefly polished 
black, first tergum entirely gray, other terga very nar-
