Argynnis platina

Butterfly, male.--The original description of this species, contained in the "Canadian Entomologist," vol. xxix, p. 154, is as follows:

"male.--Expands two and a half inches. Upper side: Rather light tawny or even light buff. Black markings dense and wide, with outer halves of wings looking rather clear or open, with rows of round spots not very large; marginal border light; bases of wings not much obscured. Under side: Superiors have the two subapical silver spots and silver spots on margin well defined; color of inner half of wing rosy. The silver spots on the inferiors are large and well defined, and placed on a very light greenish-gray ground. The intermediate buff band is well defined, comparatively wide, and very light in color. female.--The ground-color on the inferiors below is reddish-brown in the female."

Early Stages.--Unknown.

This species occurs in Utah and Idaho, and is possibly a varietal form of A. coronis, specimens agreeing very nearly with the type figured in the plate being contained in the Edwards collection under the name of A. coronis.
