the antonnaj much shorter in male ; tlic legs red, thighs

If tiie antenna} of the male were longer and more lax this 

 species might be taken for a variety of C. gratus with red

Narrow, parallel, brassy, somewhat shining ; the head very 

 closely and coarsely punctured, punctures ocellate ; the thorax 

 densely punctate, the punctures round and deep, not pressed 

 together nor ocellate on the disk, hind angles very distinctly

 elytra bright red, punctate-striate, interstices little convex, 

 punctulate, feebly rugose ; the antennte black, articulations 

 somewhat long and lax ; the legs red, tarsi dusky.

Angustatus, parallelus, obscure Cirruleo-niger ; capite tboraceque 

 creberrime oceUato-punctatis ; elytris puuctato-striatis, interstitiis
