over the rest of the surface, and a dense mass of small punctures 

 at the apex. Pygidium punctate, smooth in the middle. Legs

Length 8 lines. 



Black, subnitid. Head very rugose, with two indistinct 

 tubercles on the transverse ridge, with the clypeus subtriangular 

 and minutely trituberculate in front, and with the mandibles 

 toothed as in the last two species. Thorax not punctate, with a 

 tooth on the anterior margin and a round excavation behind it 

 in the male, — the female I have not seen. Scutellum as in the 

 last species. Elytra with a deep stria on each side of the suture, 

 the space beyond, which in the last species was smooth, marked 

 with large irregularly placed punctures, and the rest of the 

 surface covered with u-regular rows of large punctures. Pygi- 

 dium smooth. Legs and under side of body piceous red and 

 sparingly pilose.

 Length 10 lines. 



Black, nitid. Head densely punctate, and furnished in the 

 male with a blunt slightly recurved short horn. Thorax very 

 finely and thinly punctate, without any impression in the female, 

 but in the male retuse and deeply excavated in front, with two 

 rather acute tubercles at the summit of the centre, an obtuse 

 protuberance at the lateral boundary of the retuse portion, and 

 outside of these protuberances an elongate punctate fovea. Scu- 

 tellum broadly rounded, punctate at the base. Elytra piceous 

 brown, nitid, and covered with large shallow strias, filled with 

 large shallow punctures, the striae becoming less marked and the 

 punctures smaller and more numerous towards the sides and 

 apex. Pygidium very minutely punctate. Under surface of 

 body piceous. Sides of head, thorax, elytra above and entire 

 under side of body and legs ciliated with red hair.
