COLASPGSOMA. 445 



but the rugosities are confined to the depression and do not extend 

 lower down ; in nearly all specimens the basal joints of the 

 antennae are purplish. 



Length 5|-7 mm. 



Hab. Southern India : Nilgiris ; Pondicheriy ; Travancore. 



Differs from C. robitstum, Jac. in its smaller size, stronger and 

 more close puncturation of the head, the short, thick, terminal 

 joints of the antennae, and the larger non-aciculate punctures of 

 the elytra and thorax. Male organ strongly curved, somewhat 

 suddenly narrowed anteriorly, apex acute, upper cavity ovate, 

 bounded in front by a narrow smooth space.

Greenish-cupreous ; antenna; and labruin fulvous ; abdomen 

 black. 



c? . Head remotely and rather finely punctured ; clypeus scarcelv 

 separated from the face ; antenna) with the terminal joints dis'- 

 tinctly thickened, the latter black or fulvous, basal joints always 

 fulvous. Thorax rather more than twice as broad as long, not 

 narrowed anteriorly, lateral margins narrowly reflexed, punctures 

 like those on the head and similarly arranged except at the sides, 

 where the puncturation is closer. Scutellum finely punctured. 

 Elytra rather more strongly punctured than the thorax, punctu- 

 ration arranged in close rather regular rows, basal depression 

 generally obsolete. Breast metallic greenish ; legs more or less 

 a3neous ; femora sometimes fulvous at base. 



$ . Elytra with feeble basal depression, lateral interstices only 

 slightly rugose, extending beyond the middle, more strongly 

 marked near the margins. 



LenytJi 4-5 mm. 



Hab. Bengal ; Malacca. 



A female specimen, kindly sent me by M. Clavareau and named 

 by Lefevre, proves his species to be identical with my C.planifrous. 

 The author's description applies equally well to many others, as 

 no details of distinction are given. The present species is charac- 

 terized by the remote puncturation of the head, the comparative 

 strong punctures of the thorax, which have the interstices much 

 wider than the punctures and the all but complete absence in the 

 male of an elytral depression. 



The species is extremely close to C. asperatum, Lefev., and can 

 scarcely be distinguished from it, although the author describes 

 the head of the last-named species as " densely punctured " and 

 of C. serratulum as finely and remotely so, but there is scarcely 

 any difference in this respect in the specimens determined by 

 Lefevre and contained in my collection.
