3 £ and 1 9. — This is a large, pair-cinereous species, with a reddish 

 tinge. The lore wings are crossed by three reddish, zigzag bands, the basal 

 one being curved angularly on the costa; beyond are three very zigzag lines, 

 interrupted by two paler bands; the middle reddish band is less curved than 

 the basal one, accompanied on the inner side by a dusky band; this line 

 contracts slightly opposite the small, dark, narrow, oblique, discal spot, which 

 is nearer the line than in the European specimen ; this line also contracts on 

 the inner edge; the outer line is irregularly scalloped, but is straight on the 

 costa, with a subacute, curved angle on the lower subcostal nervule, below 

 which is a broad, regular sinus, rounded out, terminating in the middle of the 

 first median space, but not nearly upon or just below the first median nerv- 

 ure, as in the English specimen ; below, the line is regularly scalloped 

 between the nervules ; beyond, the submarginal line is much more dusky 

 than in the English moth, with two faint rows of white strigae on the nerv- 

 ules, with a distinct, white, submarginal line, and a black, linear scalloped 

 line; fringe dusky. The hind wings are crossed by two distinct, but rather 

 (litl'use, dusky, submarginal lines, which are more distinct beneath, and do 

 not appear in the English specimen ; beneath, it is more dusky than in the 

 specimen from England, with the outer line on the fore wing differing from 

 the European moth as described above. 



Length of body, #,0.70, 9,0.55; of fore wing, #,0.95, 9,0.80; expanse 

 of wings, "2.00 inches. 



Caribou Island, Straits of Belle Isle; Montreal, Canada (Lyman); Eagle 

 Lake, Northern Maine, early in September (Packard); Brookline, Mass., 

 May 21 (Shurtleff) ; Sierra Nevada, Cal. (Edwards). 



Specimens of this species, which were collected in Hudson's Bay Terri- 

 tory by Barnston, and also in Canada, were referred by Mr. Walker, in the 

 Catalogue of the Lepidoptera in the British Museum, to a variety of the com- 

 mon European dubitata. 



Our Labrador species agrees well with a specimen from the Fish River 

 Lakes in Northern Maine: and they seem to present indications of a climatal 

 variety of (lie European form. We have compared a Labrador and a Maine 

 specimen with a .single English specimen.
