male by a recurved ridge ; the back part of the head has two 

 subacute tubercles in the male, which, in the female, are repre- 

 sented by a straight transverse ridge. The thorax is finely 

 punctured, and has an impressed puncture near the lateral margin ; 

 in the male it is very slightly retuse in front. The elytra are 

 striated, and covered by extremely fine punctures, only visible 

 under a powerful lens ; larger punctures are also traceable over 

 their whole surface ; the shoulders are red, and near the apex of 

 each elytron, there is a small spot of the same colour.

I believe I have only the male of this species, but it is proba- 

 ble that the female differs but little from it. The head is black, 

 and lightly punctured, with two small tubercles close to the hinder 

 margin ; the clypeus is somewhat acuminated and reflexed. The 

 thorax has a dark purplish tinge, and is covered with fine punc- 

 tures. In front it is retuse, with each side of the perpendicular 

 portion slightly excavated. The elytra are strongly striated, with 

 each stria distinctly punctured. The under surface and legs are 

 deeply punctured and of a pitchy hue.

 asneo subtiliter punctato fovea utrinque parva, elytris sub-

 The clypeus in this species is rounded in front, and is covered 

 with transverse wrinkles ; the head is punctured, and almost 

 truncated behind. The thorax is of a brassy hue, and very 

 minutely punctured, with a large impressed puncture about the 

 middle of each lateral margin. The male has the thorax retuse
