1874.] 163 [Morrison. 



strongly pectinate ; claviform spot large, encircled with black ; exterior 

 line absent. A series of cuneiform dashes before the subterminal line. 



Hab. Massachusetts. 



Agrotis stigmosa nov. sp. 



Expanse 36 mm. 



Allied to volubilis Harvey, and gravis Grote. The anterior wings are 

 uniform gray, and the brownish shades of volubilis are entirely absent. 

 Claviform spot and basal streak united ; space between the normal 

 ordinary spots blackish; no cuneiform black markings in the terminal 

 space. 



Hab. Massachusetts; New York. 



Agrotis plagigera nov. sp. 



Expanse 33 mm. 



This species is allied to Edentata Grote, but the whitish streaks of 

 the terminal space are absent. The exterior line is preceded by 

 cuneiform dashes. Costa and median nervure whitish. Spots large, 

 whitish and contrasting. Hind wings gray in both sexes. 



Hab. Colorado. 



Agrotis bochus nov. sp. 



Expanse 32 mm. 



Coloration and markings of the anterior wings very similar to 

 herilis Grote, but the interior line is perpendicular instead of out- 

 wardly oblique. The male posterior wings are white, thus differino- 

 very strongly from the dark fuscous wings of herilis. 



Hab. Nebraska. 



Agrotis permunda nov. sp. 



Expanse 37 mm. 



This species resembles closely repentis G. & R., but the anterior 

 wings are uniform dark gray, without any alternation of color. The 

 median lines are simple, black and dentate. The ordinary spots are 

 obsolete. The posterior wings are gray at the base, and with a 

 broad, blackish-gray, terminal border. 



Hab. Massachusetts; Canada. 



Agrotis tenuicula nov. sp. 



Expanse 33 mm. 



Habitus and markings of Agr. conflua Tr., from which it differs in 

 the uniform gray color of the posterior wings, the presence of two 

 distinct cuneiform markings before the subterminal line and below the 

 costa, and in the size of the subterminal space, which is much wider 

 than in conflua. 



Hab. New York.
