Prothorax cylindrical, along the median line as long as broad, slightly narrower at the apex than at the base, sparsely punctate (as seen through the vestiture), transversely wrinkled before and behind the middle. Elytra subparallel in their basal half in the male, gradually widened to beyond the middle and with the apices abruptly conjointly produced in the female, flattened on the disc anteriorly, the humeri not very prominent; punctate-striate, the interstices more or less convex. Legs short and stout; anterior tibiae denticulate within. Length 6.1-7.33, breadth 2.2-2.67 millim. (male and female.) Hab. Mexico, Tampico in Tamaulipas (Schwarz, in U.S. Nat. Mus.).
