 preceded by determinate black shades; t. a. line distinctly geminate, outer

 terminal line a rigid carneous shade borders vein 2 superiorly ; orbicular 

 cinereous, decumbent, irregularly oval ; reuiform large, of the usual shape, 

 touching the gray costal region above ; with an attenuated inner darker

Agrotis repentis, Orote and RoUnson. 



The transverse posterior \me is regular, formed by little black lunulate 

 marks, which extend outwardly along the veins to the outer component line 

 which is sometimes wanting, but occasionally appears as an even distinct 

 shade. Median shade sometimes distinct and diffuse, again, as in the Colorado 

 specimen, improminent. Fore tibiae spinose.
