(latera versus paullo minus subtiliter) seriatim punctulatis, 

 interstitiis planis sparsim (^) vel minus sparsim (5) distincte 

 punctulatis ; prosterno medio sulcato ; metasterno in medio 

 et in episternis sat crebre, in parte intermedia sparsim, 

 punctulato; abdomine crebre punctulato et rugato; femoribus

 longitudine jequali. [Long. 5^, lat. 3-4i lines. 



This species bears considerable general resemblance to C. poly- 

 chromus, Pasc, but is of more robust build, with the eyes much 

 less widely separated from each other, the seiiate punctures of the 

 elytra clearly traceable quite to the base, &c. Compared with 

 C. cuprijjennis, the interval between the eyes is only about half 

 as wide, the antennee are more slender and filiform, the prothorax 

 is a little less transverse, the sculpture of the elytra is not much 

 different, the legs (and especially the tarsi) are much more 

 elongate, and the colour of the prothorax and elytra in all the 

 examples I have seen is bright purple changing in certain lights 

 to cyaneous. The outline curve of the elytra viewed from the 

 side is rather strong, with its summit at about the middle of its 

 length. There are about four punctures (in the elytral series 

 exclusive of the nearest two to the suture) in a length equal to 

 the width of an interstice.
