Geographical disirilmtion , — Ranges through the Api)alachian and Austroripariaii subprovinces 
and tlie eastern portion of the Campestrian (Nebraska), not liaving occurred west of the eastern 
borders of the great plains. Two specimens only have been recorded from any of the Ne^y 
England States, where others will jirobably be discovered, though rarely. It seems to abound 
most from Pennsylvania southward to Georgia. Orono, Me. (Mrs. Fernald); Lawrence, JMass.

Moth, — Four 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 
IL hhindaia. Thorax varying from pale to dark ash, with dark olive-grceu scales; a dark line 
across the hinder edge of the collar; over the inesoscutum dusky brownish, and on base of 
abdomen a brown patch; the teguhe edged with pale ashen scales. 
Fore wings witli the basal line indistinct, the scallop not so distinct and pointed as in 
II, hiundata; middle line doubly scalloped; the spaces between the dark scallop filled with whitish 
scales. Discal mark a distinct curved dark line inclosed in a large conspicuous lunate or oval 
pale patch; in vsoiue 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 itsell’ toward the costa in a diffuse greenish costal patch. 
There is a distinct submarginal series of about eight subtriangular dusky spots, the largest one 
situated on the first cubital interspace; this line is scarcely dislocated as compared with H, 
hhmdata. Hind wings ash, whitish in sjiots; 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 the internal angle. Beneath, the 
lines and spots do not reappear, and both wings are uniformly ash-brown, the line at base of 
fringe dusky, the fringe whitish ash, spotted with dusky. 
Expanse of wings, $ 44 mm., 9 35-52 mm.; length of body, 5 20 mm., 9 20 mm.
