Nagasaki. Also Hong Kong. N. India (Chaud.). 
Belongs to the group having a large comma-shaped pale 
spot at the apex of each elytron. It differs from C. hamifer, 
Chaud. (which occurs in Java and the island of Formosa), 
by its larger size and broader thorax, the sides of which 
are very regularly arcuated. The upper part of the comma- 
shaped spot has irregular edges.

Nagasaki ; many examples. 
Belonging in form to the group hamifer, Sagittarius, 
&c., but wanting the comma-shaped apical elytral spot 
characteristic of the group. The antennae are moderately 
short, as in that group, with the middle joints slightly 
dilated ; the dense pubescence beginning at the base of the 
third joint, which is about equal in length to the fourth. 
The palpi have subcylindrical and squarely truncate ter- 
minal joints. The form of the thorax differs fr-om that of 
C pictus and hamifer in being more narrowed anteriorly 
than posteriorly, but less so than in C. Sagittarius and 
conformis. Its surface is finely wrinkled, and the basal 
fove£e are strongly marked. The elytra are slightly 
dilated posteriorly, pubescent ; finely punctate-striate, with 
minutely punctured interstices, the punctures veiled by the 
pubescence. Body beneath black, shining and iridescent.
