joint of tarsus longest, others gradually decreasing in length. Wings longer than the abdomen. Subcostal

margin; base of the radial sector onh^ a short distance proximad of the tip of Rj ; radial sector ends 
some distance before the tip of the wing; costa produced considerably beyond the tip of the radial sector 
but not reaching the apex of the wing; media with a long fork, slighth' disconnected at the base, post- 
erior branch also slightly disconnected at its base; anterior branch of the cubitus reaching the margin, 
but disappearing before reaching the base of the wing; its posterior branch close to anal, incomplete; 
anal vein incomplete (PI, 4, Fig. 26).
