 hind tibiæ rather thickened towards the end and club-shaped ; the 

 legs have short, black hairs, anterior coxæ with brislles on the outer 

 side and at apex; front femora with an anterior bristle behind the

 the apical ; middle femora with an anterior bristle in the middle, and 

 with two or three below in the middle, of which only the anterior is 

 long; hind femora with two dorsal bristles on the apical part and 

 with one anterior near the apex; besides the femora have apical and

 curved, and hind tibiæ less dilated than in the male; front tibiæ with 

 two dorsal bristles and a very short postero-ventral bristle above the 

 middle; middle femora without bristles below, middle tibiæ besides 

 the dorsal bristles also with a small posterior bristle above the middle. ^ 



^ De Meijere gives the bristle as present in bolh sexes, but it is not found in
