Colour and sculpture of the body like those of the preceding species, 

 from which C. Bigsbyana differs principally in having the sides and the

 to it, a large humeral bilobed spot, the interior lobe of which is obtus 

 angulir or broken, and several irregular dots and spots on the elytra are 

 black-crreen.

Body, head, antennae, and legs ferruginous. Prothorax pale-yellow,

 elytrum being thickly covered with scattered minute punctures.
