of brown scales, and an indistinct cloud occupying the central portion. 

 Near the anal angle is a distinct black dot. Outer margin of wing 

 sinuous, decidedly scalloped at anal angle. Beneath the wings are 

 yellowish-white, with the outer lines very faint. The discal dot of the 

 secondaries dark brown, large and distinct. 



o — Expanse, 40-43 mm. Body and ground colour of wings much 

 more yellow than in the male, and entirely lacking the fawn-brown tint ; 

 the scattering brown scales, therefore, stand out more in contrast, those of 

 the outer area collecting into numerous short dashes. Lines, discal spots, 

 etc., as in the male. The extradiscal line is, in most specimens, more 

 sharply marked, and the shading of the central area is distinctly ochreous, 

 without tendency toward the fawn-colour, and also much paler in the 

 central portion. In the outer area, running parallel to the extradiscal 

 line, and giving prominence to the narrow white line, is a broad grayish- 

 brown band, which commences a short distance from the costa, and 

 becomes obsolete as it rounds the semicircle. Beneath a brdad brownish 

 band crosses both wings, beginning at the costa and extending two-thirds 

 across the wings. 



Described from five males and thirteen females, Yavapai Co., Ariz., 

 May 22-31 ; one male from Minnehaha, Ariz., Aug. 30 (Hutson) ; and 

 one male from Yuma Co., Ariz., Aug. 26 (Pearsall). 



Types, coll. J. A. Grossbeck ; co-types, coll. R. F. Pearsall, and in 

 Rutger's College collection. 



Seems to be very distinct from any other described species. There 

 is some variation in the intensity of the colouring, several being pale, with 

 intradiscal line of primaries and transverse line of secondaries obsolete, 

 while in others they stand out in bold contrast. The specimen from 

 Minnehaha is exceptionally dark, being heavily washed with gray, and the 

 fawn colour of the median area correspondingly heightened, and at first 

 sight suggests an entirely different insect. One of the earlier captures 

 approaches it somewhat, being intermediate between the two extremes. 

 The capture of this specimen in August seemed at first to be untimely, 

 hence the exceptional colouring ; but the later acquisition of a second 

 August specimen from Mr. Pearsall seems to establish a second brood 

 without further doubt.
