Male : Black, not shiny ; clypeus clothed with greyish-white, 

 appressed, thin hairs, head covered with a very short blackish 

 pubescence ; the prothorax is also covered with a similar tomentum, 

 but has on the sides a broad band of long, appressed, squamiform 

 whitish hairs mixed with a few flavescent ones ; the very long, 

 acuminate scutellum is concolorous ; the glabrous elytra are strongly 

 callose at the shoulder, and the triangular callus is continued as a 

 sharp ridge reaching the apex, the supra-epipleural fold is almost 

 vertical, and from the median part is so narrowed that the sides of 

 the dorsal part of the abdominal segments are uncovered, and the 

 apical part of the elytra is hardly more than half the width of the 

 base, the dorsal part is plane but the suture is as sharply carinate 

 as the dorsal ridge, the ground colour is black, but there is on each 

 side three straw-coloured patches along the suture, and a longi- 

 tudinal band along the dorsal ridge ; they are faintly punctate and 

 singly sub-acuminate rounded at apex, with the angle of the suture 

 very sharp, and they cover only a part of the propygidium ; pygidium 

 not vertical, as long as broad, acuminate, red, punctulate, glabrous 

 but having in the centre a narrow band of appressed, squamose, white 

 hairs ; the lateral dorsal part of the abdominal segments has a patch 

 of similar hairs, which form also on the three basal ventral segments 

 a band extending from the centre to half the width, the pectus is 

 sparsely clothed with a greyish pubescence, and the mesothoracic 

 epimera have each a patch of squamose hairs ; anterior and inter- 

 mediate fermora briefly pubescent ; tibiae and tarsi glabrous ; the 

 edges of the three digit-like processes of the terminal part of the 

 hind tibiae are pubescent.

Mentum elongate, sub-parallel, deeply incised in front, the lobes 

 slender, upper lobe of maxillae surmounted by a very long pencil 

 of hairs ; clypeus of about the same length as the head, slightly 

 attenuate and emarginate in front ; antennae short, club ovate, 

 shorter than the pedicel ; head retractable into a prosternal cavity, 

 in the manner of Curculionidce, i.e., it can be drawn flush with the 

 vertical margins of the anterior part of the prothorax ; prothorax
