Oblong-rhomboidal, flattened above, black, shining; a stripe on the third elytral interstice (reaching to near the apex), and sometimes a small spot at the middle of the fifth, and an interrupted series of spots and streaks along the sides of the body beneath (often abraded or wanting on the propleura), densely clothed with oblong or oval, ochreous scales, the rest of the surface almost bare. Head finely punctate; rostrum longer than the head and prothorax, stout, becoming more slender in its outer half, coarsely punctate at the sides, almost smooth above and towards the apex, the antennae inserted near the middle in both sexes, the club stout, oblong-ovate, about as long as joints 2-7 of the funiculus united. Prothorax conical, broader than long, almost smooth. Elytra triangular, flat on the disc, with one or two shallow transverse depressions towards the sides, the humeri rounded; sharply punctate-striate, the interstices flat, the third closely punctate. Beneath sparsely, the sides of the meso- and metasternum coarsely, punctate. Prosternum with a deep transverse excavation in front. Prosternum armed with two blunt spines or tubercles, and with a deep circular cavity between them; ventral segment 1 broadly excavate in the middle; anterior tibiae sparsely ciliate within. Prosternum with a shallow transverse depression in the middle before the anterior coxae.

Length 4(1/8)- 5(2/3)mm, breadth 2(1/10)- 2(3/4)mm. (♂,♀)

Hab. Guatemala, Purula, San Geronimo, Calderas (Champion).

Nine specimens. Closely related to C. comma, but with the antennal club shorter, the prosternum with a deep transverse cavity in front (instead of two foveae), the spines short, the rostrum very similarly formed in the two sexes, the prothorax more transverse, the ochreous stripe on the third elytral interstice longer, &c.
