the outer edge; above the black band are two very indistinct, narrow, brownish-black lines; the inner 
margin and two spots close to the anal angle pale yellowish-fawn-colour; the underside of both primaries 
and secondaries pale yellowish-fawn-colour, the primaries from the base to about the middle dark rose- 
pink: head and front of the thorax pale brown, the tegule and base of the thorax and abdomen dark 
brown; the underside of the head, thorax, and abdomen pale yellow; legs and antenne dark brown.— 
Female. Very similar to the male, but larger, and with most of the lines crossing the primaries very 
indistinct. Expanse, ¢ 43, 2 5 inches. 
Hab. Mexico, Cuesta de Misantla!, Jalapa (M. Trujillo), Orizaba (Boucard, in 
mus. D.); GUATEMALA, in the city (Rodriguez); Panama, Chiriqui (Trétsch, in mus. 
Staudinger). 
This very distinct species is allied to A. gannascus (Stoll) and A. rostralis, Boisd. 
The specimen from Orizaba is very much darker than any of the others before me, 
and on the underside it is reddish-brown instead of yellow. It may belong to another 
species.
