Differs from C. pu7ictulatus (apart from color and size) chiefly 

 as follows : — The clypeus viewed from in front is not sinuate ; 

 the prothorax is less strongly transverse ; the sculpture of the 

 elytra is extremely confused (and difficult to describe) consisting 

 of coarse but not deep punctures which run unevenly in indistinct 

 striae and have an ill-defined appearance, their interstices very 

 little raised and much wider than in punctulatus and extremely 

 irregular (here and there almost disappearing in vague rugulosity) 

 and generally much serrated by the seriate punctures (in 

 punctulatus the punctures of the striae being markedly coarser 

 and deeper and much more regularly seriate) ; the tibise are con- 

 spicuously shorter and evidently wider (though with similar 

 external dentation, two well defined teeth close to the apex and 

 one minute tooth at the extreme base) ; the anterior 4 tarsi are 

 manifestly stouter and shorter ; the whole insect is shorter and 

 wider. The much coarser puncturation of the prothorax readily 

 separates this species from C. advena.

This species is in general facies much like C. discedens but is 



notably blacker with the prothorax less strongly transverse and 



much more closely punctured ; the elytra also are very differently 



sculptured ; to a casual glance their sculpture might be described 



as closely rugulose the rugulosity having a seriate arrangement, 



but when closely examined they are seen to be in reality closely 



striate-punctulate, the rows of punctures so close as to be almost
