Var. Above metallic dark green or blue ; thorax with purplish 
margins ; elytra with purplish baud as in typical form. 
Length 5-7 mm. 
Hab. Southern Bombay : Belgaum ; Sangir. 
Not unlike some forms of C. pulcherrimum, but with longer and 
more pronounced purplish elytral band, which extends angularly 
nearly to the suture at the base. C. aureo-vittatum , Baly, has 
differently sculptured upper surface. In the variety, which I 
formerly considered a distinct species, the elytra are entirely 
blue with a darker purplish band, but there is no structural 
difference of importance.

Metallic green, aeneous or purplish ; antennae (base excepted) 
black ; elytra aureous, trigonal patch below base and the suture 
and margins purplish-blue. 
<5 . Head strongly and rather closely punctured, with raised 
strigae on the sides above the eyes ; clypeus strongly punctured, a 
distinct tubercle placed at the middle of its base ; antennae with 
the apical five joints distinctly widened. Thorax twice as broad 
as long, sides rounded, surface strongly and closel} r punctured, more 
conspicuously at sides than at middle. Scutelluin subquadrate, 
sides oblique and pointed at apex. Elytra scarcely perceptibly 
depressed below base, more strongly punctured than the thorax ; 
punctures very closely placed in irregular rows, larger on the side 
below the shoulders, the interstices at the latter place slightly 
rugose. 
5 . Head strongly rugosely-punctured and strigose, punctura- 
tion of thorax and elytra more closely placed than in the male, 
sides of elytra strongly rugose and wrinkled. 
Var. A bove metallic green, elytral purplish spot obscure.

I identify this as C. auripenne of Motsch. It is comparatively 
easy to distinguish in the typical form, which has the elytra blue, 
the sutural and lateral margins and transverse spot below base 
purplish. The species must not be confounded with C. ornatum, 
Jac. nor C. aureoviitatum, Baly, in both of which the sculpture is 
quite different. C. mutabile, Baly, does not seem to differ, and as 
the type of C. pulcherrimum , but not of C. mutabile, is in this 
author’s collection, the insect has evidently been described in 
error under two different names. 
The specimens from the above different localities show no 
marked differences, nor can I find any in the male genitalia.
