terior wings are light gray, unicolorous. Beneath, both wings are 

 uniform gray. 



Hab. St. Louis, Mo. Prof. C. V. Riley. 



The only specimen I have examined of this interesting species is 

 unfortunately in indifferent condition, although all the parts are pres- 

 ent. The wings are a little rubbed, and perhaps the specific descrip- 

 tion will have to be amended when fresh material is discovered. 



I give below a preliminary list, with short descriptions, of some 

 new species of Agrotis, which will be fully illustrated and compared 

 with allied forms in my forthcoming paper on that genus. 



Agrotis saxigena nov. sp. 



Expanse 40 mm. 



Allied to sigmoides Guen. It differs in the large, oblique, cinereous 

 orbicular spot, the distinct, reddish-stained reniform spot, the more 

 cinereous coloration of the wings, and the fine basal dash. The col- 

 lar is also concolorous. 



Hab. White Mountains, N. H. 



Agrotis claviformis nov. sp. 



Expanse 33 mm. 



Also allied to sigmoides Guen. 



The wings are ornamented by different shades of brown. Clavi- 

 form spot brown, very distinct. The basal and anterior portion of 

 the median space light, and contrasting with the rounded, deep brown 

 median shade. Orbicular spot concolorous, reniform stained with 

 red. Beyond, the wings gradually become lighter to the subterminal 

 line. The anterior wings pointed at the apex. The posterior 

 wings rounded, fuscous, with median and subterminal dark lines. 



Hab. Massachusetts. 



Agrotis decolor nov. sp. 



Expanse 30-37 mm. 



Allied to geniculata Grote. The spots and lines are all present, and 

 of normal form. The space between .the orbicular and reniform spots, 

 black. The basal and median spaces cinereous. The species can at 

 once be separated from all others by the subterminal and terminal 

 wings, which are uniform dull black, and by the whitish posterior 

 spaces, with a broad, even, black marginal band. 



Hab. New York; Massachusetts; Maine. 



Agrotis gladiaria nov. sp. 



Expanse 34 mm. 



Closely allied to pitychrous Grote, but the antennae in this species are
