spot at the end of each cell; antenne silvery ; under 
surface paler than above and sericeous; expanse of 
wings, 8 lines. 
tio Jurua, 7th November, 1874. 
This species appears to.be most nearly allied to A. 
apparitaria, although, judging by description alone, one 
might suppose it to come nearer to A. figurinata, Walker 
(nec Guenée) = A. tactwrata, Walker, ex parte.

Urucaca and Gaviao, Rio Jurua, 9th and 10th Noy., 
1874. 
This species appears to be most nearly allied to A. 
expolitata of Guenée, to judge from his description, but I 
have seen nothing like it in any collection.
