Head strongly deflected, retracted and invisible from above when at rest; forehead convex, covered with dense brown or grey scaling and without any central stria ; eyes broadly ovate, not acuminate interiorly. Rostrum shorter than head, somewhat ampliated at apex, its upper surface almost plane, squamose uniformly with the head at base, bare and rugosely punctured at apex; antennae ferruginous. Prothorax longer than broad, its sides scarcely rounded, broadest at base and gradually narrowed from there to apex, base deeply bisinuate, apex strongly and roundly produced above head, ocular lobes obsolete, gular sinuation very deep ; upper surface convex, closely set with large subreticulate punctures and with a distinct complete central furrow; the sculpturing is, however, very largely concealed by a thick brown or grey indumentum ; the larger punctures bear short thick erect set*, which are more numerous and paler along the apical margin. Elytra jointly trisinuate at base, somewhat broader than the prothorax at the shoulders, which are sloping, sides subparallel to beyond middle ; scutellum distinct, densely squamose but not prominent; upper surface convex, with rows of large separated foveol* which are partly concealed by a thick greyish indumentum ; the intervals narrow, plane, coriaceous, and with rows of short thick distant erect set*, which are more numerous posteriorly and a number of which unite to form a prominent fascicle on the declivity of the third interval. Legs covered with thick grey or brown indumentum ; tibiae with tw^o short stout teeth internally at apex ; tarsi short and broad, fourth joint entirely absent.

Rostrum about as long as head, straight, parallel-sided at base, very broadly and triangularly dilated on each side at apex ; upper surface plane, rugosely punctured and with a narrow central carina; antennae ferruginous, the club fuscous. Prothorax as long as broad, sides parallel from base for two-thirds of the length, then rapidly narrowed to apex, base bisinuate, apex roundly produced above the head, ocular lobes slight, gular sinuation very deep; upper surface convex, densely and evenly clothed throughout with large golden-brown scales which strongly overlap one another and with scattered depressed yellow set*.
