Long. 17 millim.

This appears to be more completely free from squamosity than any of the other species of the genus, and is of a jet-black colour. The rostrum is broad and short, with a fine, very definite channel on the middle. The rugose sculpture on the thorax is remarkably deep, and there is a median, deep, rugose groove, a little interrupted in the middle. The elevated costæ of the elytra are very definite, and the two series of large punctures in the groove between each pair of costæ are distinct; indeed the longitudinal interval separating them is more definite than usual. One pair.
