 mandibles comparatively small, with 7 teeth ; clypeus carinate, the 

 median lobe shortly anteriorly produced, its margin crenatr. 

 Thorax comparatively narrow ; legs with the tibia) only slightly 

 compressed. Node of the pedicel not so thick as in C. compressus,

Hab. Delhi (Bingham); Central India (Schurr); the Deccan

 (Smythies) ; Upper Burma (Fea, Bingham). 



A species varying somewhat in the amount of red on the head 

 and thorax, some specimens have only the head red. This and the 

 succeeding species can be distinguished at once by their remark- 

 ably silky lustre, especially on the abdomen.
