Colour brunneo-fuscous ; legs and antenna; ferruginous. 



Jiody moderately robust, not attenuated at its posterior 

 end, narrowed at about the fourth segment. 



Head sculptured below, nearly smooth and faintly sulcate 

 above. Eyes acutely angled internally, separated by a space 

 that is greater than a diameter. Antennce about as long as 

 the head. 



First tergite narrowed laterally, both the anterior and pos- 

 terior border lightly cmarginate, the anterior angle roundedly 

 rectangular, the posterior acutely rectangular ; a strong 

 marginal sulcus and two abbreviated sulci. The rest of the 

 somites with conspicuous and complete transverse sulcus, the 

 anterior covered area finely transversely striolate, the median 

 and posterior portions finely sculptured, the sculpturing con- 

 sisting of fine close-set longitudinal striolae ; the posterior 

 portion longitudinally striate about a third of the way up to 

 the pore ; pores behind the sulcus. Ventral grooves long, but 

 not quite as long as the two basal segments of the leg. 



Anal somite large, punctulate ; tergite posteriorly angled, 

 lightly constricted, the process not projecting beyond the apex 

 of the valves ; valves convex, prominent, with their margins 

 strongly compressed ; sternite triangular, without trace of 

 suture.
