there is a deep Impression ; the base is margined. The elytra 

 are rusty yellow, dull and pubescent, bluish-black at the ajiex, 

 striated near the suture, the interstices rather convex.

This species difEers only from C. nielanuras in having the 

 elytra uniform rusty yellow, and in having the third joint of 

 the antenna3 nearly three times as long as its greatest width, 

 whereas in C. melanurus it is at most twice as long as broad.

Rather a broad species. Antenna; rather stout, half the length 

 of the body, fourth joint as long as the two previous joints 

 taken together, the fifth a little shorter, the sixth and ninth 

 slightly increasing in length, very little compressed, truncate at 

 their apex. Thorax a quarter broader than long, moderately 

 shining, all the angles roxmded, especially the anterior, the 

 central impressed line reaching from the posterior to the 

 anterior margins, well defined and of equal depth ; on each side 

 are two large deep impressions separated from each other by an 

 oblique ridge. The elytra are at the base a little broader than 

 the thorax, a little wider posteriorly, red, with a black patch 

 extending from the base to the posterior two-thirds, leaving 

 the margins and the apex red ; each elytron has five impressed
