scallops or points small; al others, the scallops form deep re-entering angles, 

 and acute, needle-like points. The extremes of variation are shown in a single 

 Labrador and a single Californian specimen. In the latter, the middle band 

 is much less angulated than usual, much as in hersiliata, being broad and with 



shallower scallops, and, as in that species, the apex of the wing is squarer 

 than usual; the body is of the usual size, hut the fore wings are shorter, meas- 

 uring 0.50 inch in length. It has the brown bands; and 1 should not call it 

 a true variety. 



The Labrador form, from Caribou Island, is much like a specimen from 

 behind, labeled Cidaria truncata by Staudinger, but is much smaller. I 

 had described it as distinct, but am now, after a careful study of the species, 

 inclined to regard it as a variety, and describe it as follows: 



Var. brunneata Packard. — (Plate 8, fig. 39.) — Male antennae filiform, 

 long and slender, minutely ciliated beneath; basal joint white. Palpi short 

 and small, rather hairy, a little up-curved, scarcely passing beyond the front, 

 which is cinereous, with dark scales. Thorax cinereous, with dark scales; 

 abdomen paler cinereous. Wings quite uniform!} dark-ashen; a subbasal, 

 irregular, brown band, whitish on the costa, and edged with whitish below ; 

 a broad, mesial, dark cinereous band, three times as broad on the costa as 

 on the inner edge, with each side irregularly dentate ; on the inner side a 

 large tooth near the inner edge of the wing; on the outer edge, a large tooth 

 situated on the first median nervure. Beyond is a broad, brown band, simi- 

 lar to the inner one. narrowed in the middle by the large tooth of the mesial 

 band, margined with a paler line of acute spots, and becoming black on the 

 costa; a minute, oblique, pale, apical streak; black spots on tin; margin as 

 usual; fringe dusky; no discal dot; on the pale hind wings a discal spot, with 

 two outer, submarginal, curved lines. Beneath, paler, subluteous on the outer 

 third of the fore wings, like the entire surface of the secondaries, which have 

 a submedian dusky patch, most distinct on the costa ; fringe pale, inter- 

 rupted with dusky. Legs dark, banded conspicuously with white. 



Length of body, 0.35; of fore wing, 0.45; expanse of wings, 1.00 inch. 



Caribou Island, mouth of Esquimaux River, Labrador, August 3 (Packard). 



It may be known by its inner and outer broad, brown bands, margined 

 externally with whitish, the inner band becoming whitish, the outer blackish, 

 on the costa. Other specimens from the same locality are fully as large and 

 exactly like White Mountain specimens.
