band, one extremity resting on the costa, the other upon the upper 

 fork of the longitudinal streak, and its centre on the median band. 

 Inside the basal band is a small band reaching from the costa to the 

 longitudinal streak. Fringes yellowish. 



Posterior wings red, inclining to orange, blackish at the base and 

 along the basal half of the inner margin, with a narrow black outer 

 margin toothed between the black spots, which are arranged as follows, 

 being seven in number : one at the base, one on the inner margin, 

 two near the costa, and three adjacent to the outer margin. Fringes 

 yellowish. 



Beneath, the anterior wings are marked as above, but the colors are 

 paler, the bands more diffuse, and the veins yellow only at the outer 

 margin. The posterior wings are more inclined to orange and show 

 in addition three small black spots on the costa.

 in A. Dahurica) and the distinct V-shaped form of the median bands. 

 I have seen but one specimen and in this the antennae are wanting.
