This is, according to Lacordaire, a doubtful species, and probably nothing but a small 

 variety of C. plicata. The only constant difference, according to the same author, is the 

 division of the lateral elytral ridge into two parts in the first-named species, while in the 

 other one it is entire. 



15. Chlamys tragulus. (Tab. IV. fig. 22.)

 Eab. Hondueas, Mosquito Territory. 



The type of this species contained in the Berlin Museum has been kindly lent to me 

 by Dr. Peters, and is figured on our Plate. The underside, with the exception of the legs 

 and the extreme lateral margin of the thorax, is fulvous, the rest of the surface bronze- 

 coloured. The hump of the thorax is deeply divided by a longitudinal groove ; and each 

 side of this hump is again traversed by a shorter groove. The disk of the elytra is nearly 

 black, and limited by an oblique highly-raised ridge extending from the shoulder nearly 

 to the suture.
