Geographiatl <lislribi(fio)i. — Ranges throiigli the Appalachian and Anstioripariau subprovinces 

 and tlje eastern iioition of the Cainpestrian (Nebraska), not having occurred west of the eastern 

 borders of the great i)hiins. Two Sjieciinens only have been recorded from any of the New 

 England States, wliere others will probably be discovered, though rarely. It seems to abound 

 most from Pennsylvania southward to Georgia. Orono, Me. (Mrs. Fernald); Lawrence, Mass.

Moth. — Four S . four 9 . Ground color pale olive-greenish ashen," with white scales and 

 patches. Head above greenish ash, in front ash, and the palpi ash-colored, and generally with no 

 black scales on the outside, though in some examples there is a streak of black, but less than in 

 II. hinndata. Thorax varying from pale to dark ash, with dark olive-green scales; a dark line 

 across the hinder edge of tlie collar; over the niesoscutum duskj' brownish, and on base of 

 abdomen a brown patch ; the tegula' edged with pale ashen scales. 



Fore wings with the basal line indistinct, the scallop not so distinct and pointed as in 

 H. hiundatu; middle line donblj' scalloped; the spaces between the dark scallop HUed with whitish 

 scales. Discal mark a distinct curved dark line inclosed in a large conspicuous lunate or oval 

 pale patch; in some individuals on the inner side of this patch and extending below it is a dark 

 brown patch. 



The outer line is sinuous, the scallops shallow; the line curves outward deeply opposite the 

 origin of the cubital venules and loses itself toward the costa in a diffuse greeni-sh costal patch. 

 There is a distinct submarginal series of about eight subtriangular dusky spots, the largest one 

 situated on the tirst cubital interspace; this line is scarcely dislocated as compared with H. 

 b'uindaUi. Hind wings ash, whitish in spots; traces of an outer dusky band, distinct in the 

 center, where it is externally shaded with whitish; a diffuse sordid whitish band crosses the 

 wing, but is quite faint and best marked on the costa and at tlie internal angle. Beneath, the 

 lines and spots do not reappear, and botii wings are uniformly ashbrown, tlie line at base of 

 fringe dusky, the fringe whitish ash, si)otted with dusky. 



Expanse of wings, $ 44 mm., 5 35-52 mm.; length of body, $ 20 mm., 9 2(1 mm.
