collected by J. Steinbach in October and December. One of these 

 three, taken in December, differs quite noticeably from the others 

 in not only having the tegmina destitute of the pale sub-costal line, 

 but also quite uniformly rather prominently conspersed with fuscous. 

 Otherwise they agree fairly well with A. corumhcc.

I now have before me live males and three females of this interesting 

 little species, little, at least so far as the male is concerned. They 

 come from Cayenne, French Guiana, where they were taken in 

 January, February, and March, 191 7, by S. M. Klages. C. M. Ace. 

 No. 5873- 



This insect is interesting from the fact that the males have the basal 

 half of the wings very noticeably tinted with a delicate rose-pink. 

 In the females this tint is scarcely visible, except at the very base, 

 where it is confined to the anterior margin.
