^[iile. — Boisduva! descriites tiie male as of the size of ^i. itntlionUis: liie fore wings of a clear 

 reddish })rowii with blaclvish veins; extradiseal line oblique, black, preceded on the discal cell by 

 a large white dot. The hind wings are entirely black. The thorax reddish ycdlow; the abdomen 

 black above, with an anal brush of yidlow hairs. The wings beneath reddish, paler at the outer 

 edge, with the veins ami a coiunion line black. It is also figured by Druce in the Biologia 

 Centrali- Americana. 



1 9- Head small, not iiri/minriit. .Vnteniuv tiliform, slendei'. as usual, and much as in 

 A. xtlgnia. Head, thoi-ax, and base of abdomen uiuformly deep ocher. 



Fore wings uniformly pinkish red, almost purplish brick red. with no dark specks. No 

 basal line; extradiseal line dusky, grayish externally, not sinuous, but straight, oblique in its 

 course, ending on the costa at some distance from the apex. A rather large distinct white discal 

 spot, ^'eins dark brown. 



Hind wings produced toward the apex, outer edge convex, the wings dusky, vidns dark 

 brown: fringe dark, no discal spot, but the extradiseal line is broad, blackish, and diffuse. 



Fnder side of fore wings as above, but a little paler and the veins are darker and wider. 

 No discal spots on wings of either pair. Extradiseal line alike on both wings, heavy, broad, 

 black brown, and quite distinct. 



Abdomen black brown e.\cept at base and at tip, which is ocherous, and the hinder edges of 

 the dark segments arc narrowly edged with ocherous. Legs and under side of abdomen black 

 bi-own.

In shape this species is near .1. nih/mnda and ^1. sflr/nia, the fore wings l)eing the same, but 

 the hind wings are a little more producc^d towai'd th(> apex. In venation it appioaches Eacles 

 more than any other species examined (PI. LVII, tig. 5). 



In coloration this species widely diverges from any of the more northern or Austral and 

 Appalachian forms, showing much darker tints, and thus a diflerent facies, probably the effects 

 of its tropical surroundings.
