Head impunctate, with only a few punctures round the eyes, and the usual transverse groove; antennae entirely pale testaceous. Thorax with the sides broadly flattened, and the anterior angles produced into a short tooth, surface impunctate; scutellum testaceous; elytra rather convex, distinctly margined, minutely punctured throughout, of the same colour as the thorax, with a transverse subquadrate black band at the base, the posterior margin of which is obliquely cut, and including a small spot of the ground-colour ; a narrow lateral stripe connects this band with another fascia placed at the middle of each elytron, which has the inner margin slightly hollowed out, and is in some specimens almost connected along the suture with the basal band. The prosternum is distinctly raised in shape of a ridge, and, like the entire underside and the legs, of a pale testaceous colour. Hab. Nicaragua. Collected by Mr. Janson. 14.
