val, near tho second strife: rudimental strife at the base, short and straight; 

 epiplcurrr, with a longitudinal elevation near the base. Inhabits Georgia. 



28. Calathfs dislingucnidus. Nob. Length 5\ lines ; breadth 2 lines. 

 Piceous black, shining, smooth ; palpi, antennre and legs ferruginous ; front 



with a small impression at the base of the antennre, and a linear one near the 

 eyes: thorax smooth, with some indistinct transverse undulating wrinkles, 

 quadrangular, narrowed before, the anterior angles projecting and a little 

 rounded, base cut square, so as to make the posterior angles almost right, 

 lateral margin rufo-piceous, a little curved, dilated, and depressed posteriorly ; 

 anteriorly ; anterior transverse impression tolerably distinct : posterior well 

 marked ; medial line slight, abbreviated by the transverse impressions ; with the 

 anterior of which it forms an angle, so as to leave a well denned triangular de- 

 pression in front; basal impressions slight, scarcely distinct from the depressed 

 base of the thorax. 



Elytra striate, strife impunctured, with three impressed points on the third 

 interval, the two upper ones near the third, the lower one close to the extremity 

 of the second strife. Inhabits Georgia. 



Larger than C. gregarius, which it very much resembles ; the thorax, and its 

 margins are proportionally much wider, more curved, and more reflexed; and it 

 wants the impressed point on each side of the thorax near the margin, which 

 is very apparent in the gregarius : the anterior transverse impression is strongly 

 marked, whereas in C. gregarius, it is much less apparent. It is also much 

 darkened beneath. 



29. Anchomenus he Contei. Dej. Cat. Length 9 J lines; breadth 2 lines. 

 Very much resembles the A. exlensicollis ; but differs in the thorax being 



wider, and more rounded : the basal impressions are longer, perpendicular to the 

 base, and curving upwardly and outwardly ; whilst in the extenskollls they are 

 oblique, so as to make them wider at the base ; from this last circumstance the 

 middle of the base between the impressions is much wider in A. he Contei than 

 in A. extensicollis. 



It may, however, prove to be nothing' more than a variety.
