'Moth. — Nuineiou.s $ and 9 . Body iind wings pale cinereous, with ocherous tints, and dusted 

 "witli brown scales. Palpi brown on tlie side and above. A broad dark brown median band 

 extending from between the antenniTj back to the summit of the thoracic crest. Fore wings with 

 a basal white line which is dislocated ujjou the cubital nervule, but not forming so distinct and 

 regular an angle or point as in /. apicalts (van). A short line beyond, meeting au obli(jue line 

 ■which passes from the basal third of tlie costa to the outer third of the inner (hinder) nmrgin of 

 the wing, which, with the fourth line, forms a large V-.shaped mark. Both lines are shaded within 

 with brownish. The tbuith line is slightly bent just below the costa on the last subcostal venule, 

 but is not nearly so much so as in 1. apicnlis, and more distinct on the costa than in the middle of 

 the wing; externally this costal white mark is shaded toward the costa with rusty ocherous. 



A submarginal slightly undulating row of brown linear spots, which is dislocated inward on 

 the second cubital interspace. Fringe with dark spots at the ends of the venules. 



Hind wings with a darker waved line ju.st beyond the middle; beneath they are lighter than 

 the fore wings, with the subinedian line present. 



Expanse of wings, S , 30-3.5 mm. ; 9 , 35 mm. ; length of body, 3 , 18 mm. ; 9 , 20 mm. 

 This species is tiie most common in the Appalachian subproviuce, beiug the largest of all, and 

 is distinguished by the white costal mark on the outer third of the wing being only slightly l)eut 

 outward behind the costal edge, and not very oblique, as it is in /. apirnlis. 



It varies in hue, some individuals being dark, almost mouse-colored, and others with pale 

 ocherous as a ground color. Whether there are seasonal varieties remains to be seen. 



Var. inrersn Pack. (PI. II, figs. 110,21). Smaller, darker, more mouse-colored than F. incliisa, 

 since the areas corresponding to the light portions of /. incliifiii. are in the present form densely 

 dusted with mouse-brown scales. The fore wings are also more bent on the outer edge than in 

 normal /. iiicJiisa. The dark reddish madder-brown thoracic band narrower than in /. iiichisn. 

 Fore wings with the basal line dislocated as in I. iiicliisd, but the lower portion is slightly waved, 

 as on the outer lines. It dift'ers from I. inclitsa chietly in the costal portion of the fourth line 

 (outer arm of the V) being sinuous, and from J. npicalis in not being oblique; the costal nuirk is 

 bent outward near the costal edge, and bent inward and outward again before leaving the rusty 

 ocherous costal patch iu which the mark is situated. The third and fourth lines situated as in
