 one between the two. Hind wings, clear yellow, with a pattern of pale 

 yellowish red lines at base, a reddish line crossing middle of wing, and 

 a rusty patch at its end on the upper bi jrder. Also a large sulj-triang-

 of marginal crescents on both wings, of whitish, the central of which 

 are enlarged and 3'ellow, or sometimes silvered, this frosting occasion- 

 ally extending to two or three other adjacent ones. Expands, 1.30 to 

 1.40. Habitat, Colorado, Montana, and Kansas.
