 Manitoba is a high mountain species, usually frequenting 

 heights about 6,000 to 8,000 feet elevation. The female on upper 

 side is very blackish, with distinct spots, contrasting strongly with 

 some which follow, and which are by some writers supposed to 

 belong to the same group, as 420 b and 421 b. On underside of 

 Manitoba, on the hind wing, the white spots are pearly-white, and 

 all connected together; this point, and the blackish upperside of 

 the female constitutes the key to the species.

 Nevada is a little smaller than the preceding; the female is 

 even and smooth in colorings and the spots are indistinct, and the 

 spots of the underside are smaller, white, angular, and connected 

 together. This is a high mountain form ; the male was taken at an 

 altitude of 5,000 feet, the female at 10,000 feet, and the third at 

 7,000 feet elevation. The form of spottings on underside of hind 

 wing, combined with the softness of coloring of the female, con- 

 stitute the determinating points.
