I have seen a large number of specimens of this species, 
both from Japan and Eastern Siberia, and like Morawitz 
have been unable to see any difference between them.

Distinguished among the numerous species of the C. 
quadricolor group by its very elongate and oblong or sub- 
parallel form. The head is coarsely but sparsely punc- 
tured, and the neck depressed. The thorax is as long as 
broad, widest in the middle, and equally narrowed before 
and behind, with the exception that the posterior narrow- 
ing is slightly sinuate ; the anterior angles are much 
deflexed towards the sides of the neck, the posterior are 
obtuse owing to a slight obliquity, near each angle, of 
the hind margin ; the surface is much wrinkled and marked 
Avitli large scattered punctures. The elytra are elongate 
and not at all ovate ; the faintly punctured strias lie in 
deep sulci; the interstices are convex, and very faintly 
punctured; the dorsal surface is obscure, and the sides 
green. The underside is wholly black.
