A series of eight males and nineteen females, mostly fair, from 

 from Mr. Tom Spalding. The species is variable as has been indi- 

 cated in the description, and it has no very close allies. At first 

 sight it looks like alcesta ; but the median shade separates the two and 

 the narrower, more pointed primaries are also characteristic. 



Euxoa alcesta, new species. 



Ground color very light yellowish ash gray, sometimes with a faint reddish tinge, 

 irregularly and rather sparsely powdered with coarse blackish atoms. Head and 

 thorax concolorous, collar sometimes with a defined subapical line. Thoracic vesti- 

 ture mostly flattened hair, collar and patagia not well defined, the crest obscure. 

 Primaries with the lines all geminate, all broken and no contrasts. Basal line 

 marked on costa and below median space. T. a. line a little oblique outwardly, only 

 a little irregular; outer portion of line best marked. T. p. line with the outer line 

 vague, inner more or less crenulate, course nearly parallel to outer margin. S. t. line 

 pale, irregular, tending to form dents at its middle, marked by the uniformly darker 

 terminal space and, sometimes, by a preceding dusky shade as well. There is a 

 series of small black terminal lunules, followed by a yellowish line at base of fringes. 

 Claviform wanting in all examples before me. Orbicular round, of moderate size, 

 imperfectly defined, concolorous with ground. Reniform obscurely marked, appar- 

 ently of good size and kidney-shaped. The cell between these spots is more or less 

 darkened and sometimes even black. Secondaries white in the male, with a very 

 narrow dusky edging. In the female the wings are a little soiled, and there is a 

 tendency to an extra-median line. Beneath whitish, with a more or less obvious 

 common line and a discal spot, both best marked on primaries. 



Expands: i. 24-1. 50 inches = 31-35 mm. 



Habitat. — Stockton, Utah, Sept. 5-26. 



Ten males and six females from Mr. Spalding, all in fair condi- 

 tion. There is not much variation save in the matter of powdering, 

 which brings out a little more or less contrast, locally or generally. 

 The relationship is in part to Candida and in part to pallipennis ; the 

 former is more chunky and the marking is not well defined ; the latter 

 is even in color and does not have the powdery surface. 



Euxoa anacosta, new species. 



Ground color ashen gray, with a brown tinge, which is more obvious in the 

 male than in the female, and gives the prevailing shade of the male primaries. Head 

 paler than the ground, immaculate or with an obscure frontal line. Collar concolor- 

 ous with head and costal region inferiorly, this pale shade limited by a more or less 

 obvious black line across the middle, the upper half concolorous with thorax. Thorax 

 more or less mottled with smoky brown, differing in shade, not maculate, usually the 

 darkest portion of the insect. Primaries with costa as pale as the palest part of the 

 disk, but not contrasting. The terminal space is evenly smoky and the darkest part 

 of the wing : a dusky shade extends through and a little below the cell, and some
