 little depressed, longitudinally sulcate; frontal costa prominent be- 

 tween the base of antennae effaced below the transverse facial groove. 

 Front not greatly oblique, strongly and coarsely punctulate. Eyes

 plainly than usual. Occiput short, and, together with the cheeks, 

 prominently punctate. Pronotum rugoso-punctate, much more 

 closely so on the hind than on the front lobe, the transverse sulci 

 continuous, but not profound; the median carina showing plainly on 

 the hind, but absent from the front lobe; lateral lobes a trifle higher
