60 NORTH AMERICAN BUTTERFLIES. 



Baronii Edw. is an aberrant form with marginal lines heavy and 

 with some of the spots fused into bands, a peculiarity that I have seen 

 assumed by other members of the genus. 



130. ARGYNNIS RUPESTRIS Behr. 

 Behr's Buff-wing. 



Smaller than A. zerene but about the same color above ; differs in 

 being more heavily marked, with the spot in central cell, in third row, 

 placed nearer the outer margin of the wing, Fig. 2G, a. Beneath, bright- 

 er red on the base of fore wings, and the outer sub-marginal roAV of spots 

 are partly silvered, the remainder being wholly buff. Expands, 2.10 to 

 2.30. Habitat, California ; Mt. Shasta, Mt. Bradley, and Weber Mount- 

 ains, Utah. 



130a. Argynnis rupestris irene Edw. Differs from the type, 

 rupestris, in being darker in color above, with the spots below on hind 

 wing larger, with the sub-marginal band narrower, 



131. ARGYNNIS LAURA Edw. 



Laura's Silver-wing. 

 Size and form of A. altantis, markings above nearly as heavy, but 

 beneath, the colors are rather more red than even in liliana, and the 

 sub-marginal interspace is proportionately as large as in cybele and as 

 clear, but the silver spots are small as in atlantis. Expands 2.20 to 2.25. 

 Habitat, California and Nevada. 



132. ARGYNNIS MACARIA Edw. 

 Macaria Butterfly. 



Similar to coronis, but smaller, brighter above, with the markings 

 heavier, the crescents and inner border line of hind wing, being con- 

 nected, and in the third row the spots are continuous, Fig. 26, b. Be- 

 neath, about as pale as in nevadensis, with very little red on basal por- 

 tion of fore wings. Expands, 2.25 to 2.50. Habitat, California and 

 Nevada. 



132. ARGYNNIS INORNATA Edw. 



Plain Buff-wing. 

 Similar to A. rupestris in general markings, but differs in being 

 paler, especially the female, in having the black bordering nearly undi- 

 vided, much as in atlantis, and the spottings on hind wings are not as 

 heavy. Fig. 20, c. Beneath, tlic red at base of fore wings and on outer
