 fornia). Collected by Dr. Edw. Palmer; received through Mr. S. H. 

 Sc udder. 



Agrotis Olivia nov. sp. 



Allied to A. specialis Grote, separated by the slightly longer ser- 

 rations of the male antennae, the white instead of dark gray poste- 

 rior wings, the whitish, disconcolorous, costal shade, and the gray 

 instead of bright reddish brown ground color of the anterior wings; 

 the ordinary spots open above into the costal shade; they are pre- 

 ceded and followed by black marks; claviform spot distinct, followed 

 by a light oblique shade; subterminal line irregular; terminal space 

 dark. Expanse, 36 mm. 



Hab. Utah (T. L. Mead). 



Agrotis comosa nov. sp. 



Related to .4. fumalis Grote, differing in the structure of the 

 antennae in the male; in fumalis the antennae are distinctly serrate, 

 each serration furnished with a tuft of short bristles; in comosa, the 

 serrations are reduced to short knobs, each with a larger bunch of 

 much longer bristles. Anterior wings yellowish-gray instead of 

 gray; transverse lines as in fumalis, but the interior line is less 

 strongly lobate; median shade distinct; reniform reduced spot to a 

 black dot, orbicular apparently absent; subterminal line dentate and 

 quite distinct. Posterior wings uniform gray. Expanse 38 mm. 



Hab. Colorado (T. L. Mead). 



Agrotis hero nov. sp. 



Related to collar is and baclinodis, but separated from them by the 

 unarmed fore tibiae. 



Collar black and disconcolorous above. Thorax concolorous with 

 the anterior wings. Anterior wings crossed by two even, simple, 

 dark brown lines, the first preceded, the second followed by a pale 

 accompanying line; ordinary spots not very well defined, shaped as 

 in collaris, the orbicular preceded by a black spot; median shade 

 distinct, passing between the spots; subterminal space darker brown, 

 subterminal line indefinite. Posterior wings uniform dark brownish 

 gray, discal dots present. Beneath brownish gray, with discal dots 

 and a common diffuse median line. Expanse, 32 mm.

Agrotis personata nov. sp. 



?. Related to pit ychrous Grote. This species I have had in my
