The legs are slender, the hind legs the longest; the hind tibiae often a little thickened towards the apex and the hind metatarsi more or less thickened; the legs have shorter and longer hairs and bristles; middle tibiae with small apical or subapical spurs.

There are two claws, two pulvilh and a small, bristle-shaped empodium with bristles on the lower side; also the claws are hairy. The wings have the media- stinal vein not quite reaching the margin; the cubital vein is unforked, thus one cubital cell; the discal vein is forked, and there are four posterior cells; generally the peduncle of the discal fork is more or less indistinct and the base of the fork is generally incomplete, so that the first and second posterior cells are not completely separated. No discal cell; the second basal cell longer than the first; the lower
