tricarinate at the sides, the underside clothed with fine grey 
pubescence.

The thorax of this species is more convex in the male than in 
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 elvtral 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. Itubbed 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 antennas and legs rufo-fulvous, 
knees greenish-aeneous, tarsi fuscous ; elytra cupreous, margined 
with greenish-aeneous. 
5 . 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. 
A . 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. 
5 . 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
