Moth. — Numerous $ and 9 . Body and wing\s pale cinereous, with ocherous tints, and dusted 
'^vith brown scales. Palpi brown on the side and above. A broad dark brown median band 
extending from between the antenine back to the summit of the thoracic crest. Fore wings with 
a basal white lino which is dislocated upon the cubital nervule, but not forming so distinct and 
regular an angle or point as in J. apicalis {vau). A short line beyond, meeting an oblique line 
which passes from the basal third of the costa to the outer third of the inner (hinder) margin of 
the wing, which, with the fourth line, forms a large V-shaped mark. Both lines are shaded within 
with brownish. The fourth line is slightly bent just below the costa on the last subcostal veiinle, 
but is not nearly so much so as in 1, a2)icciUs, 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 submargiiial slightly luidulatiug row of brown linear spots, which is dislocated inward on 
the second cubital interspace. Fringe with dark spots at the ends of the venules. 
nind wings AAUth a darker ivaved line just beyond the middle; beneath thej^ are lighter than 
the fore wing.s, with the subniediaii liiie present. 
Expanse of Aviugs, <5 , 30-35mm.; 9 , 35 mm.; length of body, $ , ISinm. ; $ , 20 mm. 
This species is the most common in the Appalachian subprovince, being the largest of all, and 
is distinguished by the white costal mark on the outer tliird of the Aving being only slightly bent 
outward behind the costal edge, and not very oblique, as it is in 7. apicalis. 
It varies i*i hue, some individuals being dark, almost mouse-<'olored, and others Avith pale 
ocherous as a ground color. Whether there are seasonal A'arieties remains to be seen, 
Yar, inversa Pack. (PL II, figs. 20, 21). Smaller, darker, more mouse-colored than J. inclusa^ 
since the areas corresponding to the light portions of 7. inchtsa are in the present form densely 
dusted Avith mouse-brown scales. The fore Avings are also more bent on the outer edg’e than in 
normal 7. inclusa. The dark reddish madder-broAvn thoracic band narroAver than in 7. inchtsa. 
Fore wings Avith the basal line dislocated as in 7. inchtsa, but the lower portion is slightly AA'aved, 
as on the outer lines. It differs from 7. inchtsa chiefly in the costal i)ortion of the fourth line 
(outer arm of the V) being sinuous, and from 7. apicalis in not being oblique; the costal mark is 
bent outward near the costal edge, and bent inward and outward again before leaving the rusty 
ocherous costal patch in Avhich the mark is situated. The thiixl and fourth lines situated as in
