line strongly crenultited, parallel to outer margin. S. t. line diffuse, 

 even. Ordinary spots concolorous, incompletely defined. The orbic- 

 ular round, reniform normal, but less complete than orbicular. Clavi- 

 form faintly indicated. Secondaries of a paler shade of same color as 

 primaries. Beneath still paler with indefinite discal lunules and com- 

 mon line. The $ antennae have a bunch of subequal stiff" hair ou each 

 side of each joint. 



Expands 37""" ; 1.5 inches. 



Habitat. — Labrador. 



I have compared the type of nmhrata with the description and figures 

 of Herri ch-SchjEffer and believe them undoubtedly identical. The spe- 

 cies is well defined and easily recognizable. The vestiture, as is usual 

 with northern species, is more hairy and somewhat loose. I have also 

 received from Mr. Moeschler specimens identified by him as rava, and 

 they are the same as Dr. Packard's umbraia. The suggestionthat Mr. 

 Moeschler's dissona may be rava is wide of the mark. The species 

 seems not rare in its home.

Deep dark, somewhat blackish brown ; internal mari^in often more 

 or less reddish yellow ; stigmata bright discolorous yellow. Transverse 

 lines geminate, variably distinct; basal line evident; t. a. line even, 

 inwardly oblique and somewhat curved : t. p. line crenulate, and 

 somewhat sinuate, as a whole parallel with outer margin. T. p. line 

 pale, more or less punctiform, irregularly sinuate and i)unctate pre- 

 ceded by sagittate black dashes; the two opposite cell longest. A 

 somewhat darker shade crosses the median space. Claviform distinct 

 very narrow, not reaching middle of median si)ace. Orbicular variable 

 in size, usually rather small, sometimes i)unctiform, oblique, ovate, or 

 oblong. lieniform always well sized, kidney shaped; at each extremity 

 more or less shaded Avitli dusky. Secondaries whitish, smoky toward 

 outer margin. Beneath powdery, with variably distinct discal spot, 

 primaries with extra discal line. 



Expands 40-50"'"', 1.60-2.00 inches. 



Habitat. — New York, northward to Alaska. 



Eeadily distinguished by the elongate dark wings and the contrasting 

 ordinary spots. My dates for the species are September. 



In the male the internal margin of primaries is discolorous yellow- 

 ish, in the female concolorous. This sexual difference of color I have 

 not noticed elsewhere in the genus. This is ordinarily a rare species, 

 but a few years ago in Cauada and the northern United States there
