tlie base but towards the apex they become closer and confluent, 

 forming irregular strias ; suture with an almost obsolete row of

Pygidinm transversely convex, slightly impressed in the middle, 

 very finely and closely strigose. 



Beneath very coarsely but sparsely pimctured, prothorax 

 and anterior coxae strigose ; abdomen slightly strigose at the 

 sides with a faintly marked central line, penultimate segment 

 with a transverse row of punctures and a few at the sides of 

 the preceding one ; mesosternal process long, almost cylindi'ical,
