Male. Eyes separated, frons somewhat broad, blackish; epistoma 

 of the same coloiir, shining just at the margin. Occiput dark grey 

 with black hairs which ara long at the upper margin and curved 

 forwards. Labrum ferruginous, black at the base; palpi blackish with 

 longish hairs. Antennæ longer than the head, first joint elongated, 

 the two first joints with short hairs, the third long, with a very short 

 style. Thorax grey or brownish grey with two brownish stripes. 

 The dorsocentral bristles are longish, somewhat irregularly uniserial, 

 black; they are longer behind; no acrostichal bristles. Further a 

 humeral bristle, a posthumeral, about three notopleural, a supraalar 

 and a postalar bristle, all black; besides there are somewhat long 

 hairs on the humeri and in the præsutural depression. Scutellum 

 with two black marginal bristles in the middle and two outer short 

 and weak. Pleura grey, metapleura with long," black bristles, pro- 

 pleura with distinct, longish hairs. Abdomen black, shining, clothed 

 with short, black hairs which are longer only at the sides in front; 

 venter similarly coloured and haired. Exterior genitalia small and 

 knob-like; the eighth ventral segment large and bending up on the 

 sides, with long hairs at the hind margin; the lower lamellæ short, 

 broad and somewhat triangular, curved towards each other at the 

 apex; above, at the apex of the lower lamellæ there is a pair of 

 somewhat hook-shaped, upwards directed, reddish lamellæ and in 

 front of them a pair of short, styliform, haired processes (I think the 

 former are the upper lamellæ, the latter belonging to the eighth 

 dorsal segment). Penis is short, reddish, curved upwards between 

 the lamellæ so that only the base is seen. Legs somewhat robust, 

 hind femora thickened, hind tibiæ slightly curved and curiously dilated 

 and bent at the base ; coxæ greyish pruinose, femora black or brownish 

 black, yellow at the apex, tibiæ and tarsi yellow, the latter brownish 

 towards the apex. Front femora short-haired ; middle femora with 

 short hairs and longer bristles below; hind femora densely haired 

 below with somewhat longish hairs; posterior tibiæ with a short,
