102 LEPIDOPTERA OP NORTH AMERICA. 



characterizes the latter sex is ochre yellow; Upon the under side, 

 the wings in both sexes are green, the anterior pair tinged with 

 brown from the middle to the inner edge ; externally, next to the 

 fringe, they are all margined by a narrow wavy white line, bor- 

 dered internally with brown ; at some distance from the posterior 

 margin is another broader white line, or series of contiguous spots, 

 bordered internally with brown ; this line, on the fore wings, does 

 not reach the inner margin ; on the hind wings it consists of six 

 spots arranged in a zigzag manner, and the last spot, next to the 

 inner margin, is remote from the rest ; besides these, there are on 

 the same wings three more white spots bordered with brown, be- 

 tween the zigzag band and the base ; and between the same band 

 and the margin three black spots, behind the middle one of which 

 is a rust-red spot with a black centre. The wings expand from 

 I2V to lyo inch. This pretty species is found on the mouse-ear 

 {Gnaphalium plantagineum) in May, and on the flowers of the 

 spearmint in August.

Upper side of the male blackish-brown, with the usual ovoid 

 spot on the costal edge. The female is more dull, without the 

 costal spot, but with one or two yellow lunulate spots towards the 

 anal angle of each wing. The secondaries are without tails. 



Under side of the male is grayish-brown, traversed by a row of 

 black points circled with white, followed on the secondaries by a 

 marginal band of reddish and somewhat macular, and on the 

 primaries by a second row of black points lightly circled with 

 white. 



Under side of the female is a little more clear. The series of 

 ocellated spots is preceded in the secondaries by a discoidal black 

 streak circled with white ; the red marginal band is more sensibly 

 edged with white in front, and continues a little on the primaries, 

 where it replaces the second row of black points on the male. 



Larva, which feeds on Eupatorium celestinum, is greenish, with 

 the back a little more whitish. The anterior and dorsal part has 

 a brownish quadrangular space, bifid behind, and marked with 

 four white spots. The three hind rings have a wide whitfe border, 

 edged with brown. Head arid feet brownish.
