Moth. — Several <5 and 9 . Giouiid color of body and wings unusually dark mouse-asli, uuicli 

 <l!irkcr as a rule than in I. incUtsa. Fore wings with the basal line straisht iu its general course, 

 uiakiug a more distinct aud complete angle on the cubital vein than in /. inclusa or var. inrersa. 

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

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

 distinct white oblique sinuous mark, much more obliquely bent outward than in /. inclusa aud 

 inversa. This costal mark is bordered externally bj' a deep rusty reddish browu patch, much as 

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

 sinuous series of dark spots. Hind wings mouse colored, with a dark ditfuse transverse line 

 beyond the middle, which is often wanting. 



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

 distinct, and from it originates a darker dirtuse line common to both wings, aud on the hind wings 

 very sinuous, being bent outward behind the subcostal vein and inward behiud the cubital vein. 



Expanse of wings: S , 27 mm; 5 , 29 mm; length of body: S , 13 mm; 9 , 12 mm. 



This common an<l variable species is usually considerably smaller than I. inclusa, and I always 

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