Three specimens of the red-banded form and four entirely black, these latter from 

 Yucatan. The posterior tibiae in this insect are very strongly ciliate in the male.

 flanks), and the elytra with a narrower oblique median fascia extending inwards to the suture, rufous. 

 Rostrum very stout, curved, a little shorter than the prothorax, sparsely, finely punctate, smooth at the 

 tip, sulcate beneath, the widened basal portion also sharply sulcate above, the groove extending upwards 

 to the deep, oblong, frontal fovea. Prothorax about as long as broad, rounded at the sides, rapidly

narrowing from the middle to the short, tubulate, punctured anterior portion, the disc strongly depressed 

 and very coarsely punctate in the centre posteriorly. Scutellum large, broad, triangular, smooth, almost 

 flat. Elytra wider than the prothorax, rapidly narrowing from the rounded humeri, transversely 

 depressed at the base ; rather coarsely and deeply punctate-striate, the interstices feebly convex and 

 almost smooth. Pygidium coarsely punctate, convex, sparsely pilose at the tip. Beneath sparsely, 

 finely punctate, the ventral depression long and broad, the fifth segment with a large rounded space at 

 the apex set with long erect fulvous hairs, which show a tendency to form three small scattered tu 

 on each side. Femora and tibiae ciliate, the tibiae sinuate within, the posterior pair with a curved, 

 matted tuft of longer and coarser hairs at about the middle.

 black, the prothorax with an oblique stripe on each side, and the elytra with an oblong spot on the

 the tip, sulcate beneath, the basal portion also narrowly, interruptedly sulcate above. Prothorax slightly 

 broader than long, the sides rounded anteriorly and parallel at the base, the basal depression shallow 

 and with a few scattered punctures. Scutellum broad, subtri angular, flattened. Elytra oblong-cordate, 

 deeply and rather coarsely punctate-striate, the interstices feebly convex. Pygidium sparsely punctate,
