54 NORTH AMERICAN BUTTERFLIES. 



107a. Argynnis cybele cARPENiERn Edw. Differs from typical 

 cybele in being smaller, darker in coloration above, and rather brighter 

 below. Expands, 1.25 to l.GO. Habitat, Taos Peak, New Mexico, and 

 Montana, and Nebraska. 



108. ARGYNNIS APHRODITE Fab. 



Dark Silver-aving. 

 Plate IV, 1. 

 Size, large. Sexes, not essentially different. Above, reddish orange 

 •which is brightest on fore wings, with the base of wings but little dusky. 

 Fore wings, not heavily marked ; crescents on hind, not wide : and none 

 of the spots in third row are fused together, while the two upper are 

 placed farther from the margin than in A. cybele. All of the basal spots 

 are clearly defined, not obscured by dusky surroundings. Beneath, us- 

 ually the ferrugineous of hind wing, is brighter than in cybele, and this 

 encroaches, more or less, upon the sub-marginal interspace, between the 

 outer and second row of silver spots, and the basal portion of the wing. 

 Silver spots, twenty-five or more. Markings below m this species, as 

 in nearly all members of the genus, are variable and cannot absolutely 

 be relied upon ; thus the markings above on the hind wings, present the 

 most positive points by which the majority of the species can be identi- 

 fied. Expands, 2.75 to 3.25. Habitat, Northern, Middle, and Western 

 States, south to Tennesee, west to Nebraska, Montana, and Kansas, 

 north to Ontario, Quebec, Nova Scotia, and Fort Edmonton, British 

 America. Flies with A. cybele hi New England, and northward in June 

 and July; further south, is two brooded, occurring in June and Septem- 

 ber. 



109. ARGYNNIS ALCESTRIS Edw. 

 Ferrugineous Silver-wing. 

 Size and general coloration of A. aphrodite, but differs in having 

 the dusky at base of both wrings above, not as extended, an additional 

 round, black spot within the usual markings on hind wings, and the 

 entire absence of any clear ochcrous, sub-marginal border. Expands, 

 2.00 to o.OO. Habitat, Michigan, Illinois, Iowa, Montana, and Colorado. 



110. ARGYNNIS CYPRIS Edw. 



Cypris Silver-spot. 



Similar to aphrodite but with form of nausicaa, and the colors are 



about as bright, but the markings are even heavier, and the second spot 



on third row of hind wings above, is not as large. Beneath, the buff
