This species, of which the female only is known, is closely 
allied to A. @nea, but differs conspicuously in its darker bronze 
colour. M. de Chaudoir possesses two examples from Para. I 
do not recollect taking the insect myself; and the collections 
_which I made in the neighbourhood of Para, in the years from 
1848 to 1850, were sent to England without my reserving a set 
of the Coleoptera.
