Obs. — This insect is evidently allied to Calosoma laterale, 
Kirby : it is however distinct, and is larger than any belonging to 
this section. The posterior part of the elytra are more dilated 
than in any other species ; the deeply impressed thorax, and the 
sculpture generally, separate it from any hitherto described spe- 
cies of Calosoma. It was captured by Mr. Chas. Darwin, in the 
northern districts of Patagonia.
