Hab.MEXICO (Sallé).

One specimen, without definite locality. This is the only species of the genus known to me with a large admixture of green scales and the prothorax sharply margined at the sides behind. The last-mentioned character brings C. virescens near the Texan C. dispar (Lec.), which has the prothorax more feebly sinuate at the base, &c.
