Soft chocolate brown to walnut brown, gray brown or black- 

 ish, the lines pale, often markedly denticulate. In the cT the pale 

 luteous color of the lines may spread and predominate {luir. 

 constrictina) or cover the whole wing [jHxr. perlutea). A very 

 variable species. 



Habitiit, Rocky Mountains from their eastern slope to the 

 Sierras; Canada to Mexico. The peculiar gray from {var. mus\ 

 occurs in Utah.

Greatly resembling californica. The cJ" tends to be darker in 

 color than either californica ov fragilis, though the character is not 

 of diagnostic value. No luteous males have been observed; other- 

 wise the description of californica will apply. Separated on larval 

 characters. 



Habitat, the Pacific northwest.

cf Dark chocolate brown with a faint pale band on secondaries. 

 Lines on fore wings luteous yellow, gently curved, sharply limited 

 towards center of wing, but spreading toward base and outer 

 margin, the outer line sub-crenulate. This pale color may spread 

 till the whole wing is luteous yellow, crossed by two brown lines. 



9 Paler than the male, the ground color consequently norm- 

 ally luteus yellow, dusted with brown and crossed by two brown 

 lines, the outer crenulate. The brown scales may predominate, 

 giving a form somewhat closely resembling the male. Secondaries 

 pale or dark. Expanse, 25 — 35 mm. 



Habitat, Coast region of California
