reflections; third segment with two or four, median, marginal

 pile on the under-side ; middle tibiae with a single stout bristle on 

 the outer-side, near the middle, the hind tibiae with four or five, 

 besides the terminal ones. Wings nearly hyaline ; first longi- 

 tudinal vein bare, the third with a few bristles at the extreme 

 base ; outer cross- veins in nearly the same straight line, the 

 posterior cross-vein joining the fourth vein beyond the middle of 

 the distance between the anterior cross-vein and the angle. Claws 

 elongate. Length 12-13 mm.
