226 PHYTOPHAGA. 
C. infantula, but may be known from it by the flavous slightly raised reticulations on 
the disc of the elytra. In pallid examples the dark parts of the prothorax and elytra 
are brownish-testaceous or castaneous. |

Hab. Mexico 1-3, Teapa (Pilate, in coll. Baly). 
There is a single specimen of this species in the Baly collection, agreeing perfectly 
with the type. C. dissimilis is closely allied to C. palmata (with the antenne coloured 
as in the var. bélobata); but differs from it in the much more coarsely punctured elytra, 
the disc of the latter being yellow, with a common sutural patch before the middle, a 
short streak below the shoulders, an oblong patch at the sides below the middle 
(connected with the rather narrow, post-median, transverse, marginal fascia), and some 
scattered spots, black. ‘The type from the Stockholm Museum is figured.

Hab. Mexico !-8, Cordova (Sallé); Nicaragua, Chontales (Janson); Costa Rica (Van 
Patten); Panama, Volcan de Chiriqui (Champion).—VENEZUELA, Caracas!~*; Brazii1—>. 
Var. a. The inner part of the elytral margins from the base to the middle, as well as the entire disc, black. 
Hab. Mexico, Cordova (Sallé), Atoyac in Vera Cruz (H. H. Smith); GuaTEMa.a, 
Chacoj in Vera Paz (Champion); Panama, Volcan de Chiriqui (Champion). 
Var. 2. The disc of the prothorax and of the elytra, and the scutellum, obscure sanguineous or sanguineous.

Hab. Mzxico*—*, Puebla, Cordova (Sallé), Jalapa (Hége), Fortin in Vera Cruz 
(H. H. Smith). 
The typical form of this species, which may be known from C. plicata and its allies 
by the elytral margins being suffused with dilute sanguineous internally, has been 
collected in numbers in Chiriqui. Of the vars. a and 6 (carnifex, Boh.) single speci- 
mens only have been collected at each of the localities quoted; the var.a merely differs 
from C. melanota, Boh. (which is probably an analogous variety of C. plicata), by the 
colour of the elytral margins. Some of the specimens from Mexico and Chiriqui are 
intermediate between C. carnifex and C. rubrocincta. The disc of the elytra varies 
in colour from entirely black to sanguineous; it has usually a very large triangular
