Mazenes bifoveatus Champion 1911

Elongate, narrow, black; thickly clothed (except on the raised portions of the prothorax and on the convex elytral interstices 3, 7, and 9) with pale brown imbricate scales, with a few white scales intermixed, these latter becoming more numerous on the under surface and condensed into a sharply-defined stripe down the fifth elytral interstice; the apical portion of the elytra also set with stiff decumbent setæ, similar to those on the legs. Head and rostrum densely, finely punctate, the rostrum excavate on each side before the eyes, as well as down the middle, the eyes convex; antennæ stout, the scape widened from near the base, joint 2 of the funiculus a little longer than 1. Prothorax as long as broad, rounded at the sides anteriorly and constricted in front, densely, finely punctate; with a deep arcuate transverse groove behind the middle and an oblong excavation on the disc towards the apex, in each of which is an oblong polished shining fovea, and various other large, confluent, irregular, foveiform depressions. Scutellum well developed, convex. Elytra not wider than the prothorax, elongate, subparallel from the obliquely rounded humeri to about the middle, transversely depressed at the base and conjointly produced at the apex; with rows of coarse punctures placed along extremely fine geminate striæ, the interstices uneven, densely, finely punctate, 3, 5, 7, and 9 widened and costate, 3, 7, and 9 partly bare. Legs very stout; anterior tibiæ strongly bowed.
 
Length 11½—14, breadth 3—3½ millim. (♂ ?)

Two specimens. A remarkably distinct form, easily separable from the following by the sharply albo-lineate fifth elytral interstice, the prominent scutellum, and the very coarsely wrinkled, foveolate prothorax, the two oblong, bare, polished foveæ on which form an interrupted median sulcus.
