502 Med. SFaly’s Descriptions of 
apices of jaws black. Thorax more than twice as broad 
as long at the base; sides very obliquely converging and 
slightly rounded from base to apex, all the angles 
mucronate; disk shining, nearly impunctate. Elytra 
similar in form to those of C. Jacobyi, similarly sculp- 
tured, with the exception that the punctuation on the 
anterior two-thirds of the surface is rather more 
confused, rendering the smooth longitudinal interspaces 
less distinct ; the inner lateral costa is also less distinctly 
elevated.
