Characters. — Head small, flattened in front, placed low upon the thorax : eyes oval, somewhat 
emarginate at the base of the antennas; ocelli three in number, placed in a more or less curved line on 
the broad front, the middle smaller than the laterals; palpi incurved, four jointed, the first joint very 
small, the second and third subequal, the last one longer than the others taken together; antennae pro- 
jecting forward, somewhat compressed, 2-I-14 jointed, the basal joints cupuliform, the flagellar joints 
cylindrical; pubescent. Thorax very short, highly arched; metanotum high, scutellum small; halteres 
with elongate knob. Abdomen long and slender; in the male somewhat clavate; genitalia small (PI. 7, 
Fig. 3); abdomen in the female cylindrical, constricted at the base, seven segmented. Legs long, 
tibiae with spurs and with lateral setae. Wing elongate oval, not longer than the abdomen, microscopic 
hairy. The costa produced beyond the tip of R4-(-5 and nearly or quite reaching the tip of the wing; 
subcosta ends free or beyond the small cell Ri, which is shorter than wide, and noticeably proximad of 
the middle of the wing; K445 much curved or undulate, petiole of the media much longer than the R-M 
crossvein; the cubitus forks proximad of the fork of the media but distad of the R-M crossvein; anal 
veins incomplete (PI. 4, Fig. 6, 9). Immature stages unknown.
