1832 BUTTERFLIES BEYOND NEW ENGLAND. 



brown, paler toward the base, flecketl above with pale blue scales, the apical joint wholly 

 luteons. 



Body covered above with pallid and pale greenish hairs, below with pale yellow 

 scales and hairs, the legs pale luteous; the femora tinged with yellow, the tarsi 

 slightly embrowned ; the sptnes and claws concolorons, the tips of the latter brown. 



Wings above pale lemon yellow, in the male uniform, excepting for the mealy edging, 

 which is narrow; twice as wide on the fore wings as on the hind, with the interior 

 border parallel to the margin on the hind wings, crenulate on the fore wings; in the 

 female varying in depth from a sordid, greenish white, through a dull, rather sordid, 

 lemon yellow (and then with very slight markings) to a deeper greenish yellow, very 

 faintly tinged, especially on the hind wings with orange. Fore wings of female 

 edged with dark brown, having a slightly ruddy tint, varying in depth in different indi- 

 viduals, in the most marked running as a narrow border, beginning on the costal margin, 

 a little way beyond the cell, expanding as it goes until it reaches the apex, when the 

 width is in general constant and about half an interspace, excepting that it is consid- 

 erably crenulated, and, when not fullest developed, is seen to be composed of subcon- 

 fluent, transverse, oval spots seated on the nervure tips ; there is also a large, often 

 double, roundish spot of the same brown, at the extremity of the cell, when double, the 

 upper spot smaller than the lower, enlivened by a few clustered orange and yellow 

 scales, following the transverse veins; there is also a bent series of powdery fleckings 

 in all the subcostal and median interspaces, in the subcosto-median interspace removed 

 nearly halfway to the cell ; in those of the others which open upon the outer border, at a 

 distance of about an interspace andahalf from that border; in those which open on the 

 costal border, nearer that border ; this series of lleckings is sometimes entirely obsolete, 

 sometimes developed so as to form oblique or broken sagittate spots in the interspaces. 

 Hind wings of the female narrowly margined with long, oval, transverse, brownish 

 spots at the tips of the nervules, separated from the extreme margin only by a slender 

 orange line. 



Beneath pale, sometimes very pale, greenish yellow, often with an orange tint. 

 Fore wings with the outer margin rather broadly suffused with pinkish orange ; the sub- 

 marginal markings of the upper wing are repeated with greater distinctness and heavi- 

 ness, but still as powdery markings, generally in the form of bars orhinules of orange 

 ferruginous, flecked more or less, but never profusely, with black scales ; besides this, 

 the only marking is a spot, now almost invariably double and much larger, at the ex- 

 tremity of the cell, the central portion generally silvery, but more or less obscured, 

 sometimes entirely obscured, with orange ferruginous, and margined with black, sur- 

 rounded more or less with orange ferruginous ; occasionally a third or foui-th bit of 

 silvery or orange scales is marked oft' from the main spot by the ferruginous surround- 

 ings in the smaller portion of the spot, which lies within the cell. Hind toinys crossed 

 by four parallel, nearly straight series of slender interrupted fleckings, fiubparallel to 

 the outer margin : the flrst consists of two or three dots of clustered, ferruginous 

 scales at the united root of all the veins, the extreme base of the costo-subcostal inter- 

 spaces and in the costo-marginal interspace ; the second crosses the wing obliquely at 

 the first forking of the subcostal vein in a series of fleckings which run from the cos- 

 tal to the internal nervure, interrupted to the greatest degree at the subcostal fork; 

 the third crosses the wing at the tip of the cell and runs from the costal margin, just 

 before the tip of the first upper subcostal nervule, to the middle of the submedian ner- 

 vure, very slender and much interrupted, excepting at the extremity of the cell, where 

 it usually forms a tolerably broad and continuous belt of powdery ferruginous scales, 

 flecked with black, and enclosing at the extreme base of the subcosto-median interspace 

 and beside it in the lower subcostal interspace, a pair of circular or oval, bright silver 

 spots, each with a slender, blackish ferruginous annuUis ; the last transverse series of 

 fleckings is similar to the extra-mesial series of the fore wings, and is less regular than 

 the others, formed mainly of four slender, powdery lunules in the median, subcosto- 

 median and lower snljcostal interspaces, in the upper median nearer the margin than in 

 the other interspaces, where they are nearer the extremity of the cell than the outer
