A. fervens, Drury, vol. III. p. 58, pi. 42, f. 3. I 



obtained a female of this species in Mexico, and on com- 

 parison with an individual of the ccphalotes sent me 

 by Dr- Klug, I find it to be a closely allied species. The 

 color of the wings and their neuration are the same ; but ^ 



the body is more hairy or downy, and its brown color is 

 not so deepj (the color is much too black in my copy of 

 Drury, agreeing better with the cephalotes, tlian with 

 Drury's description.) The head is not so large, so 

 deeply indented above, nor so acute at the posterior \ 



angles. The im pressed j longitudinal line on the anterior 

 part of the thorax, so distinct in cephalotes is not, or 

 is scarcely visible in fervens. Judging from these two 

 specimens, T am convinced that the fervens ought to be 

 admitted into the modern books as a distinct species.
