interior line is nearly perpendicular, differing from the inwardly 

 curved line of scropulana. 



Hab. The same localities as A. scropulana. 



Agrotis unimacula nov. sp. 



Expanse 50 mm. 



One representative of the European augur Fabr., with which it 

 has hitherto been considered identical. It differs in its large size, 

 darker color, distinct, purple reflection, and in the absence of the 

 ordinary spots ; the only trace of the latter being a small, distinct, 

 black spot corresponding to the reniform spot. 



Hab. Atlantic States. 



Agrotis exsertistigma nov. sp. 



Expanse 37 mm. 



This species resembles the eastern alternata Grote, but it can be 

 separated by the following characters. Orbicular spot open above, 

 not sub-quadrate, as in alternata. The median space is suffused with 

 black. Claviform spot distinct and disconcolorous. The exterior 

 line is drawn in below the cell; and lastly, the collar is black above, 

 whitish and contrasting below. 



Hab. California. 



Agrotis Bileyana nov. sp. 



Expanse 33 mm. 



Coloration of repentis G. & R., to which it has a superficial re- 

 semblance. The antenna? are bipectinate. The lines disposed as 

 in repentis. Orbicular spot reduced to a black dot, adjacent to 

 the interior line. The space between the spots is unusually large, 

 as the reniform spot is removed nearly to the exterior line. It is very 

 large, black, and of the usual shape. Posterior wings whitish. 



Hab. St. Louis, Mo. 



Kindly presented to me by Prof. C. V. Riley, to whom I dedicate 

 the species. 



Agrotis manifestolabes nov. sp. 



Expanse 37 mm. 



Male antennas slightly pectinate. Anterior wings and thorax uni- 

 form reddish-brown. The ordinary lines shaped as in balanitis Grote 

 (from Colorado), and accompanied by pale shades. The spots whit- 

 ish, distinct, strongly contrasting. The orbicular small, round. The 

 reniform large, filled with black inferiorly. Posterior wings brownish 

 fuscous. 



Hab. Massachusetts, in the early spring.
