darker. Basal line distinct, black, more or less obviously geminate. 

 T. a. line forming a broad deep brown band, outwardly edged by a 

 black line, and inwardly by pale scales. Median space scantily pow- 

 dered with white scales, usually more massed toward t. a. line; three 

 broad, diffuse, smoky transverse lines beyond the middle. The reni- 

 form is somewhat lunate, elongate, inwardly edged with black scales, 

 outwardly with a more or less complete white line. Orbicular a black 

 dot or entirely absent. T. p. line very slender, black, even, rather 

 evenly outcurved over the cell, and oblique, only a little wavy, below 

 it. S. t. line a little broader, equally distinct, forming an acute out- 

 ward angle on vein 5, reinforced by a lunate black mark between 

 veins 7 and 8, and from this a blackish shade extends to the apex. 

 The space between t. p and s. t. lines is usually darker, and there is a 

 darker brown shade beyond the s. t. line, divided from it by an edging 

 of white scales. Terminal space strigillate with black; a pale ter- 

 minal line. Fringes interlined black and white. Secondaries lighter 

 brown, the disk crossed by three broad, brown lines, alternated with 

 narrow whitish lines. A geminate extramedian line, of which the 

 intermediate space is dark filled, forming a broad band edged with 

 narrow black lines, of which the outer is the more distinct and fol- 

 lowed by a narrow white line. A white terminal line, and fringes 

 with white interline. Beneath very dark fawn gray, somewhat mot- 

 tled with brown, with a common extramedian line and dark discal 

 spots. The costa is marked and spotted alternately blackish and 

 gray, there is a narrow black terminal line, followed by a whitish line 

 at the base of the fringes, and there is a white dot at the incisions 

 between the veins. 



Expands, 1.32-1.52 inches = 33-38 mm. 



Habitat. — Yavapai County, Arizona, July 22— Augusi •>: Glenwood 

 Springs, Colorado, in May. 



Types. — Rutgers College Collection: cotypes, Coll. U.S.N.M., No. 

 12030, and Doctor Barnes. 



One male and 3 females collected by Mr. Hutson; 2 males and 1 

 female from Doctor Barnes. This species is quite different from its 

 nearest allies in a number of ways. There is very little variation in the 

 material before me and very little difference between the sexes. The 

 male has perhaps a little more white powdering, but otherwise the 

 two are alike. 



In type of maculation it is like edusina, so like that it is difficult 

 to find points of distinction between the two, and with the San 

 Antonio males of the other species at hand for comparison, it seems 

 but a short step from one to the other. The only really tangible and 

 constant character in yavapai besides the very dark color is the clean- 

 cut black' line on collar, which is not present in any edusina that I 

 have seen. Nevertheless, the two species are markedly distinct, for 

 while in edusina the femoral tufting of the male is conspicuous and
