Agrotis viralis n. s. 



$ . Antennae ciliate beneath. Fore tibiae unarmed, unless accidentally 

 the spines are broken off, which sometimes occurs. Pale faded yellow fus- 

 cous 5 collar with a faint line. The lines obsolete. A blackish dash at 

 base ; another below it on internal margin ; a dash across submediau 

 sj>ace, and the cell before and between the stigmata darker shaded. 

 Stigmata pale, concolorous, moderate. Orbicular outwardly oblique, near 

 the reniform at base ; both stigmata incompletely dark ringed. S. t. 

 line indicated ; s. t. space paler ; terminal space darker. Hind wings 

 paler, nearly concolorous with fore wings, darker shaded along outer 

 border. Body concolorous; beneath without markings; hind wings

Agrotis atrifera Grote, Bull. U. S. G. Surv. 4, 173. 



Both sexes of this species havebeen taken by Mrs. French at Orono, Me. 

 The Maine specimens only seem to differ from my California types by 

 the orbicular being complete and the black discal shade a little more 

 extended. The female has the hind wings a little darker. 



Agrotis brunneigera Grote, B. B. S. N. S. 3, 80. 



Specimens have been taken in Washington Territory by Mr. Morri- 

 son, and in Colorado by Mr. Neumoegen, which I cannot well separate 

 from my Vancouver types (9 s) of this species in my collection. The 

 stigmata are more obliterate and the color of a lighter fawn brown. 

 The median lines are variably distinct, vividly contrasting, or, in one 

 specimen, nearly obsolete. There is a black line on the collar as in/tts- 

 eigera. The male antennae are brush-like. 



The Noctuidae from Washington Territory belong in many instances to 

 the same species found in California, about San Francisco, and Yancou- 

 ver Island. Among such species are the following : 

 Hadena divesta. 

 curvata. 

 indirecta. 

 Mamestra cuneata. 



cinnabarina. 

 Agrotis brunneigera. 



gravis. 

 Plusia labrosa. 

 Deva palligera. 

 Actinotia Stewarti. 



Hadena separans n. s. 



$ 2 . Allied to devastatrix, but darker, shaded with blackish. The 

 subterminal line forms a more decided M -mark, but not cutting the 

 fringes ; a black dash connects the small claviform with the exterior 

 line; the internal margin has a black streak at base. The terminal 

 space is shaded with blackish above and below its central constriction
