tricarinate at the sides, the underside clothed with fine grey 

 pubescence. 



Length 5-6 mm. 



Hob. Bengal: Mandar. 



The thorax of this species is more convex in the male than iu 

 any other of its Indian congeners, and resembles that of some 

 African species of the genus ; the sides are very strongly rounded 

 at the middle ; the elytral depression is very feeble in both sexes, 

 but in the female (if rightly referred to this species) the thorax 

 is less convex and the sides are less rounded, the puncturation 

 also of the elytra is closer and finer. Eubbed female specimens of 

 C. albovillosum can be distinguished from this species by the 

 shorter and much more strongly transverse thorax.

Metallic green ; labrum, base of antennae and legs rufo-fulvous, 

 knees greenish-aeneous, tarsi fuscous ; elytra cupreous, margined 

 with greenish-aeneous. 



$ . Narrowly oblong, convex. Head and thorax deeply but not 

 coarsely punctured ; antennae black, slender, filiform, two-thirds 

 the length of the body, basal five joints rufous or fulvous. Thorax 

 more than twice as broad as long, sides rounded, roundly narrowed 

 in front. Elytra oblong, sides parallel, more coarsely punctured 

 than the thorax, slightly broader than the latter ; disc transversely 

 impressed below basilar space, strongly rugose and tuberculate at 

 the sides. 



<5 . Elytra with the sides closely transversely rugose, without 

 tubercles. 



Length 6 mm.

Elytra and legs variable in coloration ; some specimens have 

 the elytra metallic green with a lateral cupreous stripe, in others 

 the stripe is wanting ; the legs are either coloured as given above 

 or metallic green.

p. 114. 



Greenish-cupreous ; antennae, legs and abdomen fulvous. 



$ . Head finely and rather closely punctured ; the clypeus 

 similarly punctured, indistinctly separated from the face ; labrum 

 and antennae fulvous. Thorax very short, nearly three times as 

 broad as long, the sides very strongly rounded, slightly narrowed 

 in front, the surface coarsely and not very closely punctured, the 

 sides more closely so. Scutellum broader than long, with a few 

 punctures. Elytra rather finely and regularly punctured on the 

 inner disc, the outer half entirely covered with strongly raised
