 branch before or at the end of the cell, but not infrequently 

 the two branches fork from a short footstalk beyond the cell, 

 hs in the female. 



1 have little doubt that this group of species branched ^ off 

 from Dismorphia as a development from D. nasua and allies, 

 which curiously approach it in coloration and somewhat in 

 outline of wing.

cJ. Very like A. nemesis, but without the yellow veins 

 and streaks on basal half of primaries ; the yellow patch on 

 secondaries narrower, owing to the presence of a dark brown 

 dentate-sinuate border which extends along the outer margin 

 to the submedian vein. 



Expanse of wings 67 millim.
