Resembles C. pennatum, but the elytra are unicolorous, and of a dull brick-red colour. 
In our examples they are not infuscate round the scutellum as in those described by 
M. Bourgeois; but I have little doubt they pertain to the same species, which hardly 
differs from C. pennatum except in colour. Five specimens, all females.

Hab. Nicaraeva, Chontales (Belt, Janson). 
A great number of this species were met with by Mr. Champion in Chiriqui. The cells 
are often dark with pale coste, especially towards the apical half of the elytra; and in 
one specimen from El Tumbador this fuscous black colour extends over the apical two- 
thirds, thus connecting the type form with the variety with a black apical third. 
Calopteron terminale (p. 14). 
To the localities given, add :—Panama, Volcan de Chiriqui, Bugaba (Champion). 
Three specimens, two male and one female, maintain the characters given by me for 
this species; the sinuation of the sides of the thorax is similar to that of C. rufulum. 
It appears rare, and is easily overlooked among C. lineare, &c. 
One male specimen from Chontales, taken by Belt, has the apical third of the elytra 
infuscate. A typical female appears to have been taken at the same time.

A species easily to be recognized by its thorax being carinate in front, and channelled 
behind, much as in Plateros; but the elytra have only four coste, and the intervals with 
large squarish cells. ‘The specimens met with by Mr. Champion in Chiriqui have the 
legs, for the most part, almest wholly yellow; it varies, however, in this respect—they 
are sometimes almost black with only their bases yellow, as in the specimens from 
Guatemala. The head, thorax, elytra, scutellum, two or three apical joints of the
