 rostral ridges broader, sulci and foveas deeper. Prothorax less 

 dilatate. Elytra broader, with more pronounced humeral angles, 

 and more evident intrastrial granules; the tubercles on the third 

 and fifth interstices transverse or else duplicated (except on de- 

 clivity). The undersurface convex, with a feeble, interrupted 

 vitta on the last three segments; longitudinal impressions feeble.

Though closely related to *S'. occidpnfalis Sloane, this species 

 can be readily distinguished by the distinctly larger tubercles on 

 the second interstice. In both S. occidentalis SI., and S. arigusti-

 than those on the other interstices. 



The clothing is only distinguishable under the lens; to the 

 naked eyes, the species appears destitute of clothing.
