Abstract
The species of Drapetis are to be distinguished from the remainder of the Empididæ by the following summarized combination of characters. Thorax robust, the humeri not swollen and constricted. Eyes closely approximate on the face, but on the front diverging above; palpi broad, incumbent on the very short proboscis; antennæ three-jointed, with terminal or subterminal arista; one pair each of vertical and ocellar bristles. Legs hairy and often furnished with bristles or setæ, the middle femora however rarely armed and not thicker than the front pair. First basal cell of the wings shorter than the second which is united with the discal cell, anal cell completely wanting, only two posterior cells before the anal area.
