 straight, entirely transverse: occipital foveas deep, very far 

 apart, lateral grooves convergent, dilated anteriorl}^ and lost in 

 the plane of the depressed middle portion of the front. The 

 frontal margin anterior to the median plane is very narrowly 

 retuse, the antenna! tubercles more prominent than in the 

 other species. AntcnncB scarcely as long as the head and pro- 

 thorax, first joint obconical, as thick as the tubercle, second 

 oval, slightly smaller, third to seventh subequal, gradually 

 becoming more transverse, eighth and ninth transversely oval, 

 tenth three times as thick as the eighth and one-half longer

 punctulate, slightly wider than long, fovea oblong, deeper at 

 the base. Elytra one-half longer than the prothorax, measure 

 across the shoulders the same, across the tips one-fifth wider. 

 All impressed lines parallel, the basal fovea sharp, rounded,
