REVISION OF SPECIES OF THE GENUS AGROTIS. 153 



tliougli sometimes smaller. Claviform short, narrow, outlined. Sec- 

 ondaries smoky, base paler. Beneath i)ale, i)0\vdered with dusky; an 

 incomplete conunon line and discal lunule. Uead and thorax concolor- 

 ous, mixed with a few yellowish scales. 



Expands 3i-37""" ; 1.35-1.50 inches. 



JiABiTAT— Vancouver, Colorado, Arizona, Washington, Nevada; 

 northwestern British Columbia. 



This is a somewhat narrow-winged species, very variable within com- 

 paratively wide limits, a^d yet at the same time recognizable from the 

 fact that there is no other strncturally allied species with which it can 

 easily be confounded. A series of specimens from northwestern Brit- 

 ish ("olumbia, which I refer here show an almost immaculate foruj, 

 varying to one in which the ordinary spots are yellow pow<h'red ; in none 

 of the specimens are the transverse line at all traceable, yet I can 

 scarcely consider it a distinct species. The black form of infelix to 

 which attention has been already drawn, may ultimately i)rove to con- 

 nect the two names into the most widely variant species known to me. 



Carueades finis Siiiitb. 



1887. Smith, Proc. U. S. Nat. Miis., x, 457, Afjrotis. 



Sordid brownish fuscous, a more distinctly rusty brown shade in sub- 

 basal and s. t. space. Transverse lines geminate variably distinct, but 

 evident in all observed si)ecimens. T. a. line oblique, outwardly curved 

 between veins, not more prominently beneath vein 1. T. p. line even, 

 slightly crenulate, parallel with outer margin. S. t. lino pale, narrow, 

 very slightly and irregularly sinuate. Claviform concolorous, short, 

 evidently outlined. Ordinary spots rather large ; orbicular round, red- 

 dish gray, powdery; reniform kidney shaped, narrowly annulate with 

 yellow, the yellow somewhat encroaching in the middle, outwardly. 

 Secondaries dull yellowish fuscous, paler toward base, the veins and a 

 dis(!al lunule dusky. Beneath powdery, more percejitibly toward a])ices; 

 an exterior distinct dusky line, and dusky discal si)ot. Head and thorax 

 concolorous ; collar with a transverse brown line, the patagiae at base of 

 primaries tipped with ferruginous. 



Expands 34"""; 1.35 inches. 



Habitat.— Black Hills, JMontana. 



This species is iu»arest to jxtstonilis, but is smaller, and the ]uimaries 

 are more obtuse. The distinct transverse lines and the well-marke<l 

 brown shades in s. t. and sjibbasal spaces render it very distinctly 

 recognizable, though they somewhat obscure the relationship to this 

 group. 



Caineades velleripennis Grt. 



1874. Grt., r. Kept. Peab. Ac. Sci., 25, Agroth. 

 Smoky black, the transverse maculation indistinct or entirely obso- 

 lete; the ordinary spots large, concolorous, more or less comi)letely
