From Brazil. — The colour of the wings on the 

 upper side is yellow-ochre. The size is somewhat 

 smaller than the following, Ac. Sirena ; the back 

 angle of the present species is also very cornered, 

 by which it deviates from the rest of this genus. 

 A broad part of the tip and exterior edge of the 

 superior wings is black, as also a narrow band, 

 which is however very broad in front, extending 

 from the middle of the front border, towards the 

 back angle, to the external edge. The middle of 

 this transverse band unites by an oblique black 

 line with the black tip of the wing. Between the 

 roots of the wings and the transverse band, there 

 are, at the front edge, four small scalloped trans- 

 verse streaks, which have a resemblance with those 

 of the species Argynnis, F. On the lower wings 

 there is a black exterior edge, which is thickened 

 towards the back angle, by two fine black scalloped 

 streaks, and some black scalloped stripes at the 

 root. On the under side the chief colour is light 

 yellow. The transverse band of the superior wings 

 is here brown and indistinct. Two fine scalloped 

 brown lines surround the exterior edge of all the 

 wings ; similar lines are seen at the root of the 

 superior ones, and the front half of the lower
