I 'use black, clothed with hairs like those of the thorax and without 

 distinct bristles along the hind border ; squamae brown, yellow- 

 fringed ; halteres with a white knob. Abdomen black, but sometimes 

 red at the hind border and sides of the second segment ; the hairs are 

 like those of the thorax, but longer and tuft-like toAvards the end ; the 

 bristles at the hind borders of the segments are yellow and longer 

 than the hairs, but very thin ; venter with reddish hairs. Legs 

 entirely yellow and with yellow spines; hind femora with 5-6 long 

 yellow spines at the underside ; claws reddish yellow, with black tip. 

 Wings with yellow veins and with yellow basal comb ; upper branch of 

 the cubital fork much retreating at the base ; first posterior cell acute 

 at end and with a rather short stalk ; second posterior cell very short, 

 much broader than long ; discoidal cell short and broadly obtuse at 

 end, the discal cross-vein placed a little after its middle. The wings 

 are greyish hyaline, but with a faint infuscation extended to the fourth 

 longitudinal vein and to the cross-vein ; there are traces of three less 

 distinct dark spots on the ends of the second and of the first basal 

 cells and on the base of the second submarginal cell.
