violaceous hue of the middle part of the elytra extends over 

 the whole elytra, or, becoming rich purple (brilliantly metallic 

 on the thorax) spreads over the whole surface of the body. The 

 width of the S/"*^ interstice and the depth and punctuation of 

 striae 1-3 vary considerably.

This fine species is met with also on the Naga and Khasia 

 Hills and in the Andaman Islands. The thorax varies in colour 

 from fiery-coppery to golden and blue-green.

I have seen many examples of this species from Assam and 

 the Khasia Hills. Individuals with violaceous elytra, as described 

 by Schmidt-Goebel appear to be in the minority in Burma, the 

 more prevailing colour being blueish-black with greenish-blue 

 border and some examples have brilliant-coppery head and tho- 

 rax, the last-named approach C. cyanipennis (Chaud.) of Northern 

 India, which cannot be more than a local colour variety of the 

 species, having coppery head and thorax and indigo-blue, non- 

 metallic, elytra.

There is no difference whatever except the blue-green head 

 and thorax between C. aeneus (Mots.) and C. cupreicollis. C. cu- 

 preicollis appear to be an abundant insect in the Andaman 

 Islands. C. aeneus {fuscoaeneus, Chd.) is found in the Malayan
