and concave front (same as signature). There is a strong hair at the 

 tip of each clypeal band and another, longer, on the inner edge at the 

 lateral constriction of the signature, with a small spine near it. Tra- 

 beculae are long, heavy, and curving and end in a point nearly at the 

 apex of the second antennal segment; antennae long and heavy, with 

 segments 2 to 5 deeply colored and with strong bristles on segments 

 1 and 2. 



Pro thorax small and rather rounded, with heavy lateral bands and 

 coxal markings. Pterothorax considerably wider but veiy short, 

 with convex sides, rounded lateral angles, and flatly rounded posterior 

 margin thickly set with 18 very strong, pustulated hairs. The 

 abdomen is almost round (0.715 by 0.65), with narrow, deeply pig- 

 mented pleurites and with paler tergites extending but halfway to the 

 median line of abdomen, ending in a rounded point, and set with four 

 to eight very long, strong, pustulated hairs on posterior margins. 

 Tergites I to VI are overlapped by succeeding scleritcs along outer 

 portion. There is a series of long dorsal hairs across the median 

 hyaline portion of the abdomen, along the posterior margins of the 

 segments. 



The genital sclerite is very large, covering much of segments V to 

 VII, has a chxular anterior margin, and ends in a rounded point in 

 the anterior portion of VIII; two long, coarse, pustulated hairs occur 

 on the lateral portion of the genital plate. There are small, more or 

 less oval sternal plates lying under tergites I to VII and two larger 

 ones under VIII; also long sternal hairs along median portion of 

 posterior edge of segments I to IV; segment VIII is large, rounded 

 posteriorly, and deeply incised medially. The species is represented 

 by a single female, the type.
