The elytra, as in E. longipilis, have a short fulvous 

 pubescence, besides the longer hairs ; the apices are 

 unispinose, with a black streak proceeding from the 

 spine. The thorax has no black lateral streak, and the legs 

 are entirely unicolorous. The posterior spots of the elytra 

 are not longer than the basal one, but are a little more 

 pointed.

Also closely allied to E. longipilis ; differs in its 

 glabrous surface, having but very few long hairs, except 

 on the antennae and legs, and wanting entirely the short 

 pubescence. The lateral spines of the thorax are very 

 small and acute, which gives the thorax a more cylin- 

 drical appearance. The ivory spots are margined before
