Primaries not obviously strigillate 23 



22. Patagia divergent, whitish discolorous; reniform whitish with brown 



lines cingulifera. 



Patasia normal, not discolorous: reniform dusky, not outlined Colorado. 



23. T. p. and s. t. lines distinct, forming an obvious outward angle at

Ranges in ground from creamy or blue gray to yellow brown. In 

 the brown specimens the head, thorax, and abdomen are concolorous; 

 in the pale specimens the head is usually gray, the collar and anterior 

 portion of thorax brown; rest of thorax and abdomen gray. Collar 

 always with a black transverse line. Primaries with basal area, a 

 triangular costal area between t. p. and s. t. lines and often a diffuse 

 area at middle of costa darker brown and in the gray specimens con- 

 trasting. T. a. line marked chiefly by the difference in tint between 

 basal and median space, very oblique, only a little outcurved. Ordi- 

 nary spots vaguely indicated or altogether wanting. Orbicular small, 

 brown, punctiform; reniform upright, narrow, a little constricted, 

 concolorous and only definable when there is a brown shading ;it 

 middle of costal area. T. p. line black, slender, outwardly denticu- 

 late in all the interspaces below the cell. S. t. line brown, tending to 

 become broken and partially lost, inwardly convex to the middle 

 where it extends in a brown shade to the outer margin and thence 

 again, not so much incurved toward the inner margin. Secondaries 

 with a double extra-median line, of which the outer is the more con-
