The Californiaii and Kocky Mountain examples arc; shaped like tlic Tc(;- 

 land ones, hilt with the inner edge of the mesial liand on the fore wings 

 heavier. The I'eniales are much larger Ihan easlern ones, e.\])anding 1.30 

 inches. The single Peimsylvanian individual does not diderlVom Ihevvesfern 

 examples. The Labrador examples usually liave heavier markings, and in 

 nearly all cases shorter wings than in the Iceland or Californiaii exam|)les. 

 A single Labrador example ag^■(>es well with an Iceland one which diders a 

 little from the normal lorm, the median l)an(l lieing very broad, with the 

 edges less heavy than usual. AVestcrn and Californiaii examples have the 

 fore wing 0.62 inch long. 



1 append a description of the example I descrilxnl as slrigata: 



Male antenuLU well pectinated, dark, eoncolorous with (he front and 

 the palpi, which are long and slender, especially the third joint. Fore wings 

 with two basal lines; a broad, black band, contracting greatly just before tin; 

 hind edge, where it is about one-third as broad as on the costa; a broad 

 mesial tooth on the outer edge, l)elow a little siuuated. This band is accom- 

 panied on the outer edge In' a marginal dusky l)an(l. Beyond is a row of 

 tine, nervular, l)lack dots; a sul)marginal, wliite, zigzag line, going ol)li(piely 

 to the apex. On the costa is a suliapical jjair of lilaek stripes, tin; inner of 

 the two being oblirpie. The hind wings are ])ale, with \vv\ faintly-iiKirked 

 lines; luteous beneath toward the apex ; two dark lines beneath, the outer 

 one consisting of dots. Discal dots distinct. Abdomen dusky, with tiie seg- 

 ments edged with white. 



Length of liody, 0.40; of i()re wing, 0.50 inch. 



Diilers in its broadly-pectinateil antemne, the broad, mesial, l)lack l)aiid 

 narrowing rapidly on the inner edi,^^ : also, by the distinct discal dol, ami the 

 quite distincl dusky line along the outer margin of the l>and, with the distinck 

 ol)liqiie, Idack line on Ihf! costa near the apex, and the lilack dots benealh 

 the spot on the nervules.
