Size of P. cardui, and in many respects similar, but the outer 

 edge of the primaries is usually more emarginate ; the summit has 

 a slight blue reflection, and it is browner on the under side. The 

 interior white spot is more narrow and bent outwards. There is 

 a white point between the extremity of this band and the internal 

 angle. 



Upper side of secondaries also very similar to P. cardui. 



The under side is brown, slightly obscure, with nervures of a 

 yellowish- white, crossed near the base by two lines of this color. 

 In the middle, there is a transverse band of white, a little grayish, 

 or of a rosy white, followed exteriorly by two ocellated spots. Near 

 the posterior edge, there is a marginal band of nearly the same 

 tint, divided in its length by a violet undulated line. 



In the females, the tint of the upper side is sometimes carmine 

 or brick color. 



Larva blackish-gray striated with yellow, with the segments 

 more clear, and the first rings more obscure. Along the feet, and 

 below the stigmata, a yellow lateral ray, and above these another 

 yellow ray, marked with a small orange spot above each stigma. 

 The spines are yellow. Feeds on Gnaphalium oUusifolium. 



Chrysalis yellowish, of the same form as that of P. cardui, scat- 

 tered with a large number of golden spots.
