 with short, fine hairs; anal tube small, brownish yellow. Legs yellow, 

 hind femora a little darkened at tip and likewise hind tibiæ; hind 

 femora somewhat broad, with only short hairs below the basal half, 

 but with the hairs on the anterior side of the ventral margin in the 

 apical half long and bristly; hind tibial bristles large, few in number. 

 Wings somewhat yellowish, veins brown or pale brown ; costa reaching 

 to the middle, 1 about equal to 2 + 3; costal cilia long; angle at 

 fork acute, third vein dilated from the base to the fork and very broad, 

 also the outer branch of the fork thick; fourth vein a little S-like at
