This is another of the handsome genera of Cerambycide characteristic of Central 
America and the adjoining regions. Hight species have previously been described, 
none of which extends further beyond the zone included in the scope of this work than 
Texas on the one hand and Colombia on the other. The Texan species (C. rimosus) 
differs in some essential points from its congeners.

Two specimens of this superb insect have been sent home by Champion, both 
females. I believe I am right in referring them to C. iridescens, White, of which the 
male only has been described. The colour of the elytra, however, is more intensely 
metallic, showing no trace of pale ferruginous ground-colour. The sculpture of the 
thorax is similar in the two sexes, thus differing greatly from the closely allied species 
C. rimosus of Texas, in which the male only has a thickly sculptured thorax (no smooth 
dorsal space being left), the female having the same part smooth, with only a few 
scattered punctures. On the authority of M. Sallé, C. tricolor (Waterh.) has been 
recorded as the female of C. iridescens; but C. tricolor differs greatly in the sculpture 
of the thorax, and belongs to quite a different section of the genus. The grooves of the 
third to fifth antennal joints described by White (in which the female specimens agree 
with the male) are a strong indication of affinity with C. rimosus, which has in both
