AMERICAN LEPIDOPTERA.

marks and inscriptions heavier than in the male; on secondaries the 

 discal band is either of separated lunules, but larger and nearer 

 together than in the male, or the posterior half of the band is con- 

 fluent, while the outer remains separated. 



Under side of primaries deep red, passing into dark brown near 

 the apex; the silver spots as in the male; secondaries wholly dark- 

 ferruginous, or often olive black, as in Idalia, with no pale band be- 

 tween the outer rows of spots; the spots large and well silvered. 



E(j(;. — Of same general pattern as the eggs of Ci/hele, Aphrodite, 

 and other of our large species of Argynnis, but longer in proportion 

 to the breadth than in any of them so far known, the sides straighter 

 also and less rounded. Laid upon violet. The larva emerges in 

 about twenty-four days, and hybernates in its first stage. It cannot 

 be distinguished at this stage from the larva of either of the species 

 named. 



This species is found in Northern Illinois, Iowa and Colorado, and 

 has been regarded as a variety of Aphrodite. I have examined large 

 numbers of examples the past season, and am satisfied of its distinct- 

 ness. The coloration of the under side of secondaries is remarkable, 

 many of the females resembling Idalia in this respect, while other 

 females and the males are covered with one uniform shade of bright 

 or dark-ferruginous brown, free from all mottling like that seen in 

 Aphrodite. 



Chrysophauus IVais. 



Male. — Expands 1.4 inch. Upper side yellow-fulvous, spotted and 

 shaded with black; hind margins edged by a black line, and a paler 

 narrow border, followed by a common fulvous belt, on the posterior 

 edge of which is a series of rounded black spots, of equal size, and 

 completely crossing each wing; next preceding is a common, narrow 

 black band, wavy on the inner half of primaries, and all of secondaries ; 

 from this to base primaries have the ground fulvous, but blackened on 

 both margins; secondaries have the corresponding area fuscous, except 

 the cell, and a narrow extra-discal belt, which are fulvous ; both wings 

 crossed by a discal row of rounded spots ; at the extremity of each cell 

 a black transverse bar, and three others within, near the middle, and 

 in a group; also below each cell are three similar bars; fringes black 

 and white in irregular areas. 



Under side of primaries orange, except a little spot of bufi", quite 

 at the margin in each interspace, and a sub-apical stripe of same color 

 reaching nearly to end of cell ; the hind margin edged by a heavy
