Moth. — Nuiueious $ and 9 , Body and wiiio-s pale ciiKneous, with ochei'ou.s tints, and dii.stcd 

 "with brown scahjs. I'al|)i brown on the .side and above. A bioad dark brown median band 

 exteiidino' from between tlie antenine back to the .summit of the thoracic crest. Fore wings with 

 a basal white line which is di.slocated upon the cubital iierviile, but not forming so distinct and 

 regular an angle or point as in /. apiealis (rau). A short line beyond, meeting an obli(iue line 

 ■which passes from the basal third of the costa to the outer third of the inner (liiuder) margin of 

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

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

 but is not nearly so nuicli so as in 1. apiculis, and more distinct on the costa tlian in the middle of 

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



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

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



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

 the fore wings, with the submedian line present. 



Expanse of wings, i , '.W-X> mm.; 9 , 3.") mm.; length of body, $ , 18 nun.; 9 , 20 mm. 



This species is the most common in the Appalachian sub])rovince, being the largest of all, and 

 is distinguished by the white costal iiuirk on the outer third of the wing being only slightly bent 

 outward behind the costal edge, and not very obliipie, as it is in /. apiealis. 



It varies iu hue, some iiulividiuils being dark, almost mouse-colored, and others with i)ale 

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



Var. mcersa Pack. (PL II, figs. 120,21). Smaller, darker, more mouse-coloied than F. iiiclxsa, 

 since tlie areas corresponding to the light portiiins of /. inrlunK are in the ])resent form densely 

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

 normal /. inclma. The dark reddish inadderbrowii thoracic band uai rower than in /. ijichisa. 

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

 as on the outer lines. It differs from J. iiivliisa chietly in the costal itortion of the fourth line 

 (outer arm of the V) being sinuous, and from /. apiealis in not being obliqiu-; the costal mark is 

 bent outward near tlu> costal edge, and bent inward and outward again before leaving the rustv 

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