We have only received one example of this species, but it has the structure of the rostrum so peculiar that I have thought proper to describe it. Possibly the character may be confined to one sex, which in that case may prove to be the male, as this example has a small mucro at the inner margin of the apex of the middle tibia. The rostrum is scarcely so long as the head and thorax, rather stout and curvate, and is provided beneath with a large lamina extending from the insertion of the antennæ to the apex; the antennæ are short, quite black, with unusually abrupt club, and are inserted very near to the eyes; these latter are moderately large and are separated by a wide interval. The thorax is rather small and narrow, much narrowed in front, closely and coarsely punctured, with a very short inconspicuous channel in front of the scutellum. The elytra are rather narrow, somewhat deeply but not broadly sulcate. The clothing of the surface is very inconspicuous.
