Of this species also I have seen only males. There is little 

 superficial resemblance to the other species of the genus. 

 It is a more oblong and less convex insect, clothed both 

 above and beneath with long erect liair. There is a slight 

 metallic green lustre, except upon the head (which is densely 

 rugose and opaque, with the clypeus straight in front and 

 very short) and tiie bright yellow outer part of the elytra. 

 The scntellum is smooth and bears only an external fringe 

 of white setse, and the elytra are decorated in the sutural 

 region with vaguely-indicated clusters of similar but not 

 erect setse. The prouotum and elytra are less strongly 

 sculptured than in the preceding species, and the elytra are 

 less dilated behind the shoulders and only slightly narrowed 

 behind. The pygidium is clothed with very long hairs. 

 Tiie antennae, as usual in the male, are very slender and the 

 legs are moderately long.

Although closely related in all essentials to Dichelomorpha 

 this genus is very different in its general aspect. It is not 

 clothed with scales, but with rather coarse hairs and setae. 

 The interlocking mechanism of the pronotum and scntellum 

 is much more developed than in Dichelomorpha, the base of 

 the pronotum being furnished with two angular projections
