^[o^h. — Several S and 9 . Ground color of body and wings unusually dark mousea.sli, mucli 

 darker as a rule than in I. inclma. Fore wings with tlie basal line straight in its general course, 

 Tiiakiiig a more distinct and complete angle on the cubital vein tlian in I. inclusa or var. inversa. 

 Second line slightly bowed inward, meeting the short third line on the cubital vein. The V-shaped 

 mark (composed of the third and fourth Hue) distinct; its outer arm ending on the costa as a 

 distinct white oblique sinuous mark, nuich more obliquely bent outward than in /. hicliisa and 

 iiirt-rsa. This costal mark is bordered e.Kterually by a deep rusty reddish brown patch, much as 

 in 7. inclusa, the patch often being more or less ftided and obsolete. A submargiual, slightly 

 sinuous series of dark spots. Ilind wings mouse colored, witli a dark diffuse transverse line 

 beyond the middle, \\liich is often wanting. 



Beneath, the wings are concoloroils with the hind wings above; the whitish costal mark 

 distinct, and from it originates a darker diffuse line common to botli wings, and on the hind wings 

 very sinuous, being bent outward behind the subco.stal vein and inward behind the cubital vein. 



Expanse of wings: i , 27 mm; 9 , 29 mm; length of body: $ , 13 mm; 9 , 12 mm. 



This common and variable species is usually considerably smaller than I. inclKsa, and I always 

 recognize it by the very distinct and oblique white costal mark (as I will call this costal ending
