Moth. — "Primaries grayish wbite, witli a fawu-colored shade along the internal margin, 

 especially toward the base of the wing. The anterior lines are ob.solete, the posterior is broken 

 on the costa, but its course may be traced by a series of imperfect streaks, nearly to the posterior 

 margin, thence about the middle of the wing it forms a very acute angle to the center of the 

 internal margin, and is slightly dentate outwardly. There is a conspicuous discal mark, some 

 streaks near the apex of the costa and others near the internal angle, blackish brown, fringe 

 fawn color. Secondaries sordid white, with a blackish blotch on anal angle, and the fringes and 

 margin dusky. Beneath, the wings are sordid white, shading into dusky on the costa, the primaries 

 broadly so, and inclosing some blackish streaks. Antenute fawn color. Thorax brownish fawn 

 color, mottled with darker shade, the collar brown-black. Abdomen sordid white, shading into 

 fawn color at the base. Legs fawn color, mottled with brownish. 



"Expanse of wings, 38 mm. One 3 , Colorado, Coll. H. Edwards." (Edwards in Papiho, ii, 

 pp. 125, 120, Oct., 1882.) 



This species may be easily recognized, and differs from its nearest ally, S. eximia, by the 

 distinct linear discal mark. It has on the fore wings near the internal angle a series of brown 

 slashes and a row of whitish-gray and dark slashes ou the costa, near the apex, otherwise the 

 Utah example is like it. The hind wings are white, with a dark spot on the internal angle; the 

 wings are not dusky, nor with a whitish diffuse line such as is present in 8. eximia. A S in Mr. 

 Neumoegen's collection from Canyon City, Colo. (PI. VI, fig. 6), has the reddish colors of 8. eximia, 

 but it may be at once separated from it by the large linear discal mark. The fore wings are crossed 

 by reddish zigzag lines. The large dark shade or blotch beyond the discal mark is present, and the 

 black slashes on the costal region and at the internal angle are well marked. The long black streak 

 on the base of the wing, along the cubital vein, is present and very distinct. A S specimen from 

 Ogden, Utah (U. S. Nat. Museum, PI. VI, fig. 5), is much bleached, without the reddish-brown zigzag 

 lines, and the fore wings are very pale silvery white on the costal region ; the veins are darker, the 

 linear discal mark is indistinct, and beyond it is the usual dusky patch. The black stripes at the 

 base of the wing extending along the cubital vein, and also along the inner edge, are distinct. The 

 hind wings are white, with a dusky discoloration along the internal angle. 



Expanse of wings, S 41-43 mm.; length of body, $ 20-21 mm. 



Geographical distribution. — A member of the Campestrian subprovince, it is not known to 

 exist either east or west of the Great Basin and Colorado Plains. 



Denver, Canyon City, Colo. (Bruce, in Neumoegen collection); Salt Lake, Utah (Edwards); 

 Ogden, Utah, June 20, 1885 (U. S. Nat. Museum), Colorado (French); State of Washington 

 (Strecker). I have examined this specimen, which extends the distribution of this species to near 

 the Pacific Coast unless it occurred in a locality in the State east of the Cascade range.
