1494 THE BUTTERFLIES OF NEW ENGLAND. 



ously above with dull white at the extreme base, distinctly beneath, both iu front and 

 behind, with snowy white on the basal half, and behind also, on the apical half of most 

 of the joints, especially toward the club, cither a little less distinctly tlian on the l)asal 

 half, or witli a distinct dash along the middle, growina; more and more conspicuous, 

 until on the club all merge into a uniform field of white; tlie lower anterior half of 

 the club naked and dark castaneous, the upper lialf of the field dusky, but the apical 

 joint wholly naked and castaneous. Tongue dull black, changing to luteous at 

 extreme tip. 



Thorax covered above with mingled dark brown and blackish luiirs and scales; be- 

 neath with scarcely pale-tipped dark browu hairs tinged witli purplisli. Legs dark, 

 purplish brown, more deeply tinged with purple and othenvise darker above than be- 

 neath, the upper surface of the tarsi not so dark as that of the femora, occasionally 

 flecked with ashen, or pale along the inner surface. Spurs purplish brown, flecked 

 with ashy, and tipped with pale reddish. Spiues dull luteous ; claws the same at base, 

 reddisli at tip. Pad blackish. 



Wings above very darlv, warm brown, tinged slightly witli vinous, especially on the 

 fore wings. Fore viimjs with a cellular, vitreous spot and an extra-mesial series of 

 similar ones ; the cellular spot is generally obsolete in the $ and in the ? scarcely 

 ever more than a roundish dot, situated just beneath the base of the second superior 

 subcostal nervule. The outer series consists of distinct subcostal and median sets; 

 the subcostal of four minute, generally unequal, quadrate or oblong spots, the lower 

 occasionally and rarely all but the second from the top obsolete, situated in the suc- 

 cessive interspaces below the second superior subcostal nervule, the middle ones usu- 

 ally the largest, the series scarcely larger iu the ? than iu the $ , antl arranged in 

 a straight or nearly straight line estendiug from the base of the first superior subcostal 

 nervule to the middle of the outer border; the median spots are occasionally both 

 obsolete, the lower frequently in the $ ; when present they are generally, especially 

 the upper, a very little larger than the others and are placed somewhat before the 

 middle of the two median interspaces ; in a single $ only is there a dot in the lowest 

 subcostal interspace. The extreme base of the wing is obscured by dark clouds, while 

 the other dark markings, excepting at the outer border, are darker tlian usual, Ijeiug 

 almost velvety black ; the intra-mesial band is of irregular width and interrupted; it 

 extends from the costal margin, its outer linut at tlie tip of the costal fold of the $ , 

 to the middle of the basal two-thirds of tiie subraedian nervure and is composed of 

 two parts, divided, or sometimes united slenderly at the median nervure; the upper 

 portion is broad, of nearly equal average width, crossing the wing at right angles to 

 the costal margin, strongly strangulated in the middle of the cell and expanding again 

 on approaching the median nervure ; the lower portion is usually narrower, crosses the 

 medio-submedian interspace at right angles, its interior limit striking the base of the 

 lower median nervule, is generally lanceolate and often sends a slender shoot, some- 

 times a rather broad one, across the base of the lower median interspace to join the 

 upper portion ; the cell is also crossed midway Ijetween the intra-mesial baud and 

 the base of the wing Isy a narrower bar or lunule. the lower outer angle of which joins 

 the lower part of the intra-mesial band ; the extra-mesial Ijand is usually of about the 

 width of the upper portion of the other and of the medio-submedian interspace, of equal 

 average breadth throughout, rather strongly sinuous in direction, passing from the 

 costal margin midway lietween the tip of the costal fold of the $ and the tip of the 

 wing to the middle of the outer two-thirds of the submedian nervure, enclosing at its 

 interior edge tlie subcostal vitreous spots and just within its middle the median vitre- 

 ous spots. Above the median area and especially in the interspaces beyond the cell 

 the spots are often less intense and always have their interior limits less clearly defined 

 than below, where the edges are marked with unusual clearness, l)eing regularly undu- 

 late, opening toward the base in the interspaces; extern.-iUy the spots are lanceolate, 

 especially in the upper half of the wing, and the lowest are usually followed out- 

 wardly by a paler, grayish area, reaching to the submarginal spots; the submarginal 

 series consists of independent roundish spots, increasing in size, becoming more and
