Differs from any other species known to me by the conspicuous s-shaped 

 line in outer third of fore wing.

8 i and 8 9. — Pale whitish-gray. Orbits and palpi tinged with ochre- 

 ous. Fore wings with four costal spots, from which more or less obsolete 

 lines run in a taint series of dots across the wing; second spot the broadest, 

 the discal dot forming a part of the line ; third spot forming with a part of the 

 line proceeding from it a large irregular s, extending to the middle of the 

 wing, the line continuing beyond in an interrupted series of fine dots, and 

 with a supplementary spot at the end of the s. Half-way between the s and 

 the apex is a fourth small costal dot. Hind wings with an obscure discal 

 spot, and a submarginal transverse shade ; the wing is faintly mottled with 

 smoky dots. Beneath, both wings with fine transverse subochreous spots; the 

 lines appear beneath of a smoky ochreous, the third line being less sigmoid 

 than above, as it is curved outward to the angle, and then goes obliquely and 

 in a straight course to outer third of inner side. Discal dots distinct, as 

 above. Hind wings with a distinct outer subochreons broad band near the 

 edge of the wing. A row of dark dots along edge of both wings.

It may be known by the s-like third costal spot, the more yellowish tint 



of the under side of the wings, and by the presence of an outer shade on the 



hind wings. The sigmoid spot is much like the bent spot in the middle of the 



wing in Thamnonoma wavaria. It is a common moth west ot the Mississippi, 



extending from Kansas to Texas, and common on the Pacific coast. It varies 



a good ileal within these limits. In a Nebraska specimen, the extradiscal
