4. Stigmal area of wings brown ; male hypopygium conspicuously hairy, the 



dististyle with four or five prongs (Fig. 41, B) ; wings ($) small and 



tending to be atrophied (wing, $, under 10 mm.) autumnalis

 small, not conspicuously hairy; wings ( 2 ) of normal size, over 12 mm. .calcar 



5. Cell Ma long-petiolate. .I/3+1 longer than ni-cn ; wing-pattern chiefly as a broad 



brown seam along cord ; size large (wing, S , over 13 mm.) auripennis

 without a conspicuous brown seam along cord; size smaller (wing, $ , under 

 10 mm.) 6 



6. Wings with a heavy brown pattern, including large circular clouds at 5"(\. 



and origin of Rs, the latter not crossing cell C: abdominal segments gray, 

 conspicuously banded with paler ; basal two antennal segments yellow, the 



remainder black vernalis 



Wings with a restricted brown pattern, extensive only in viacatcci. where 

 the area at Sc^ crosses cell C to the margin ; abdominal segments brown or 

 brownish black throughout (except in katahd'm, where the basal segment is 

 pale) 7 



7. Wing-pattern heavy, especially a costal series of about five darkenings, some 



of these (at least that at Sci) reaching the front margin of wing. . . .macateei 

 Wing-pattern very restricted, including only small spots and dots at intervals 

 along veins, with cells C and Sc nearly clear 8

yellow, the remainder of organ black katahdin
