Moth. — Sev^eral $ and 9 . Ground color of body and wings unusually dark mouse-asli, mucli 
darker as a rule than in 7. inclusa. Fore wings with the basal line straight in its general course, 
making a more distinct and complete angle on the cubital vein than in L inchisa or var. inversa. 
Second line slightly bowed inward, meeting the short third Hue on the cubital vein. The V-shaped 
luark (comi)O.sed of the third and fourth line) distinct; its outer arm ending on the costa as a 
distinct white oblique sinuous mark, much more obliquely bent outward than in I. inclnsa and 
inversa. This costal mark is bordered externally by a deep rusty reddish brown patch, much as 
in J. inclusay the patch often being more or less faded and obsolete. A submarginal, slightly 
sinuous series of dark spots. ITiiul wings mouse colored, with a dark diftuse transverse line 
beyond the middle, which is often wanting. 
Beneath, the wings are concolorous with the hind Aviugs above; the AAdiitish costal mark 
distinct, and from it originates a darker diffuse line common to both wings, and on the hind wings 
very sinuous, being bent outward behind the subcostal vein and inward behind the cubital vein. 
Expanse of wings: $ , 27 mm; 9 , 29 mm; length of body: S , 13 mm; 9 , 12 mm. 
This common and variable species is usually cousiderably smaller than J. inclusa., and I always 
recognize it by the very distinct and oblique Avhite costal mark (as I will call this costal ending
