of the length of the head and thorax together, the eighth joint 

 much smaller and shorter than the seventh. The thorax is trans- 

 verse, rounded on the sides, and when looked at from in front, 

 it appears even a little broader than the elytra; it is cut 

 straight at the base, and has the posterior angles a little project- 

 ing backwards. The scutellum is triangular. The elytra are 

 oval, obliquely emarginate at the extremity towards the suture, 

 with the exterior angle projecting in a point. On each side of the 

 suture there is an impressed line which reaches a little beyond 

 the half of the elytra. The anterior tibise are a very little 

 dilated*." 



The emargination of the elytra at the apex of the suture fur- 

 nishes an easy character for distinguishing this species. 



M. Motschoulsky mentions that he took it in spring at Ana- 

 nur, on the great military route of Georgia, and in the month 

 of August, near Davial, on the same route. It was found under 

 stones, and in the earth, among roots, in obscure places. The 

 specimens which have been recently excluded are often of a tes- 

 taceous colour.

The above meagre description is all that we know of this 

 species; it would, however, rather appear to belong to this 

 group.

" Testaceo-ferrugineus ; thorax angustior quam elytra. 



1 - A species remarkable on account of its thorax being much 

 narrower than the elytra, which are of a tolerably broad oval, 

 and acuminate at the extremity. The fades approaches nearly 

 the genus Pteroloma, but the body wholly removes it. It is of 

 a ferruginous-yellow colour, and is found on the summits of the 

 alps of Hamar-Daban in Mongolia J."
