. The whole insect is of a dull black, covered rather sparingly 

 with ashen coloured scales, and with all the tubercules or 

 granules furnished with a decumbent black seta. The rostrum, 

 which is as broad as the head and square, has the apex 

 triangularly emarginate, and presents three shallow longitudinal 

 grooves on its upper surface, terminating behind in a transverse 

 impression deeply marked at each end. The head in the male 

 is armed beneath with a strong subacute horn, pointing back- 

 wards. The thorax is closely covered with hemispherical tuber- 

 cles, and has the medial dorsal line distinct near the base. The 

 elytra are elongate, truncate at the base, which is their narrowest 

 part, and rounded at the apex, where they terminate in two small 

 curved points. Their whole surface is coarsely rugose, with rows 

 of large punctures separated by rows of tubercles, of which every 

 alternate row is larger, the fourth row from the suture forming 

 itself into a rather prominent humeral angle. The anal forceps 

 is strong, but rather short, only just shomng itself beyond the 

 apex of the elytra. The female is rather shorter and thicker 

 than the male, without any horn under the chin, and with the 

 anal segment of the abdomen large and without excavation. 



This is by far the most common species of the genus, and
