There is a Carabus in the National Museum of Chili that, to a 

 certain extent, resembles this species. It differs, however, in its 

 longer elytra and slightly in markiug ; and as this species was 

 described from a single specimen, I hesitate to describe a closely 

 allied species without seeing more specimens. The specimen in the 

 Museum was taken many years ago in the " Cordillera Pelada," in 

 Valdivia; and although I have searched assiduously in the same 

 locality, I have not been able to obtain more.

This species is very variable in size, in the form of the thorax, 

 and in the degree of development of the " chain strige " of the 

 elytra ; but it may always be distinguished from its nearest allies by 

 the coarse punctation of the underside of the thorax. I have met 

 with an extreme form which I was at first inclined to consider a 

 separate species ; it may be thus characterized : — 



Carabus buquetii, var. elegantissimus. (Plate XIII. fig. 5.) 



Rather smaller and more slender than the ordinary form ; similar 



in colour except that the thorax is much darker, and its golden 



margin narrower or imperceptible. In form it is distinguished bv the 



strikingly narrower thorax, the greatest width of which is near the
