“Pronotum: Nearly uniformly dark brown to black; punctation dual, larger punctures small to moderate and rather coarse. Elytra: Dark brown to black; each elytron usually with orange to red markings as follows: a basal spot attaining suture and usually attaining middle of elytron at side, an apical spot, a basal spot often attaining apical spot at side of elytron, light markings infrequently expanded and leaving only anteapical dark spot, or even with elytron entirely light. With nine (sometimes evidently eight) rows of punctures, rows five to eight crowded and sometimes confused, rows six and seven usually confused, one or the other often much reduced; punctures as large, dense as usual, finer at elytral apex; inner and outer rows distinct at apex, usually clearly uniting. Prosternum: Anterior margin in male strongly produced into a pointed lobe; anterior margin in female produced into a broad, pointed lobe. Length: 5.0 to 6.3 mm” (White, 1968: 79-80).
“A series of specimens in the U.S. National Museum from Mexico and Honduras determined as C. militaris Suffrian is very similar to pubiventris. They differ in that the dorsal surface (except the orange markings) is usually distinctly bluish or greenish, the orange markings at the apex of the elytra are often reduced or absent, and the basal orange spot never attains the apical spot when the latter is present. A single specimen from Mexico determined as C. smithi Jacoby is quite similar to pubiventris except that the basal spot does not quite attain the suture” (White, 1968).
