margined with black. Elytra not deeply punctate-striate, the 
punctures still finer posteriorly but visible, interstices flat, trans- 
versely wrinkled at middle, opaque near apex, the markings 
variable in size. Pygidium generally with an obscure brown 
marginal spot and a central black spot at base ; prosternum 
broadly produced at middle of anterior margin. 
Var. a. Thorax without spots ; elytra with three small black 
dots (2 . 1), one on shoulders, one obliquely inwards between 
third and fourth row of punctures and the third behind the 
middle, midway between first and second spot ( C . emails , 
Oliv.). 
Var. b. Thorax with two transverse black spets, placed widely 
apart. 
Var. c. Thorax with two large transverse kidney-shaped 
patches ; elytra with a transverse band at base and a large trans- 
verse spot behind the middle black. 
Length 5-7 mm. 
Hah. Bengal; Nilgiris ; Coromandel; Tranquebar. 
In well-marked specimens the sides and last segment of the 
abdomen are flavous, middle portion black, and the pygidium with 
a black spot at middle of base.

“ 2 • Eale fulvous ; head with three, thorax aud elytra with two 
black spots ; beneath black ; abdomen margined with red. 
“ Head with short central deep groove at vertex, closely and 
strongly punctured, as is also the clypeus ; a broad frontal and a 
small round spot at base of each antenna black ; the latter pale 
fulvous, scarcely half the length of the body, distinctly widened 
terminally from beyond the fifth joint. Thorax remotely but 
coarsely punctured, margins and a central line pale, edge of 
posterior margin and two widely separated spots at middle black. 
Scutellum triangularly elongate, black and shining. Elytra raised 
round scutellum, epipleural lobes short but distinct; surface regu- 
lar^ punctate-striate, coarse anteriorly, intermediate rows finer 
at middle, interstices slightly raised, finely wrinkled, less shining 
than thorax, basal and sutural margins narrowly black ; the spots 
large, transverse, the basal spot near margin obliquely placed 
towards suture, equally distant from either margin, posterior spot 
behind the middle, nearly as long as broad between second 
and eighth rows of punctures. Pygidium black, finely silvery 
pubescent margined with fulvous. Prosternum, middle of first 
abdominal segment and margins at sides yellowish-red ; anterior 
edge of prosternum broadly produced, hollow'. 
“ Length 4| mm. 
“ Hab. Southern India. 
“ Closely resembles C. analis, Oliv., but smaller and with 
entirely different elytral sculpturing.” ( Suffrian .)
