1U54 THE BUTTERFLIKS OK NEW ENGLAND. 



of thorax covered above with loiij;, pale greenish yellow hairs, on the posterior portion 

 more yellowish, anteriorly i;ra(l(ially becoming strongly tinged with brown ; patagia like 

 the anterior portion, but their outer edge and posterior tip yelloMish; thorax beneath 

 covered with short, uniformly yellow hairs and scales. Legs nearly uniform, dull, 

 pale luteous ; coxae tufted beneath with yellow hairs, which are paler on the posterior 

 than on the anterior surface; the femora covered with pale canary yellow scales, the 

 anterior surface of the hind pair often with a broad stripe of lemon yellow scales; 

 tibiae and tarsi sprinkled with very pale yellowish scales ; tibial spurs pale, tipped 

 with reddish brown; spines dirty pale; claws varying from fuscous to dusky brown, 

 pale at base; paronychia pale, often fuscous at tip; pad pale fuscous. 



Wings above uniform, bright canary yellow, a very little brighter in the $ than in 

 the $ , the costal border of the hind wings, as far as the subcostal nervule, except in 

 the apical half of the wing, paler. In the $ , the upper surface of the wings is 

 entirely without spots, excepting that the extreme tips of the nervules not infrequent- 

 ly have an inconspicuous brown dot, especially upon the fore wings ; and the costal 

 border of the fore wings is delicately edged in front, but not above, with lilac brown ; 

 The wings are also sufficiently diaphanous to show the spots on the middle of the 

 wings beneath. There is a bordering of raised scales on the upper surface of the 

 wings of the $ ; on the fore wings (44: 5, G) it occupies the whole of all the sub- 

 costal interspaces but the lowest, but without reaching the nervures, especially at the 

 base of the interspaces ; along the middle of the lower subcostal interspace it reaches 

 two-thirds the distance to the base of the interspace, and forms a very greatly pro- 

 duced triangle; below this in each interspace to the submedian interspace is a series 

 of arched spots reaching from one to two interspaces' width inward but connected 

 only at the extreme edge of the wing ; a rather narrow band follows the inner border 

 from the tip of the submedian nervure two-fifths the distance to the base of the wing ; on 

 the hind wings it forms a narrow, nearly equal border from the costal nervure almost 

 to the lowest median nervnle, less than half an interspace in width. In the $ , besides 

 the front edging of the costal border, the fore winrjs have the apical fourth of the 

 same border edged to a greater or less extent but alwaj's rather narrowly and usually 

 interruptedly with dark brown, having a maroon tinge; the same color but often hav- 

 ing a pinkish hue occurs in distinct roundish spots at the extremity of all the nervures, 

 terminating on the outer border, usually occupying a little less than the width of an 

 interspace, but occasionally almost commingling to form a border, uniting with that at 

 extremity of costal margin, which in this case is more than usually pronounced; the 

 spot at tip of submedian is always smaller and more obscure than the others ; the 

 outer border is very narrowly edged with pinkish and at the extremity of thediscoidal 

 cell is a large, irregular, but roundish, dark brown spot, occupying almost the entire 

 width of the base of the subcosto-median interspace, never reaching the median but 

 sometimes crossing the lower subcostal nervule; its middle or the middle of its inner 

 two-thirds is traversed by the vein closing the cell, which is either simply defined by 

 orange scales or becomes the nucleus around which, nearly in the centre of the brown 

 spot, a pretty large pupil of mingled yellow and pinkish orange scales is formed. The 

 hind wings agree witli those of the $ except in having the spots at tip of veins a lit- 

 tle, sometimes considerably, larger and the outer border delicately and faintly edged 

 with pink. Tlie short fringe of all the wings in the ^ is pale, partially covered at 

 base and sparingly flecked at tip with blackish brown, excepting below the lower 

 median of fore wings and above the middle subcostal of hind wings where it is gen- 

 erally yellowish ; at the tips of most of the nervures it is wholly brown ; in the 2 it is 

 essentially as in the <? , only partaking to some degree, especially at the base, of the 

 pinkish tinge of the edging of the wing and in having a little greater proportion of 

 dark scales. 



Beneath of a duller, frequently more greenish and less pure color, the whole surface 

 being very distantly flecked to a greater or less extent with pinkish brown atoms, 

 although occasionally, in the J', these are exceedingly rare or entirely wanting, in 

 which case the color is nearly as brilliant as above and the wings have no spots what-
