1088 THE BUTTKKKLIES OF NEW ENGLAND. 



base of the femora slightly fiiseous. covereil with yellow scales, the terminal tarsal 

 joints slightly inf uscated ; spurs pale, tipped with dark red ; claws blackish. 



Wings above canary yellow, slightly paler and sometimes duller in the female. 

 Basal half of the costal border of the /ore wings, especially in the female, broadly 

 sprinkled with (mostly concealed) blackish brown scales, the apex with a broad patch 

 of blackish brown, the inner border of which starts from the costal border, at about 

 tlirce-lifths the distance from the base and extends in a concave curve, with two or 

 three M'aves on the lower half, as far as the lower median nervule, where it is of the 

 breadth of an interspace, and either terminates abruptly ( $ ) , or continues, of thesame 

 width as here, to the inner border (<? ) ; a slender black cross line marks the extremity 

 of the cell, sometimes reduced to a mere point; apical half of the costal border, in the 

 female, dull whitish, interrupted with dark brown at the nervure tips ; the nervTires 

 crossing the dark Held are black and the outer margin is marked by a black line, beyond 

 which the basal half of the fringe is dark brown and the apical half f errngineo-roseate ; 

 fringe of the inner margin yellow. Jlind wings with a few black scales at the extreme 

 base and the rest of the wing immaculate excepting next the outer border, where it 

 either has a bordering of blackish brown, commencing at the costal border in the 

 middle of the costo-snbcostal interspace, as broad as an interspace as far as the middle 

 of the lowest subcostal interspace, where it suddenly diminishes one-half in width and 

 then, narrowing gradually but constantly, passes as far as the tip of the lowest median 

 nervule, slightly dentate at all the nervures and ending in a mere line(^); or, the 

 band is reduced to a series of blotches, the upper a large one, generally occupying 

 only the extremity of the upper subcostal interspace and the adjacent portions of the 

 adjoining ones, the others short streaks, largest apically, surmounting the tips of the 

 subcostal and median nervules ( ? ) ; occasionally, in the latter sex, these markings are 

 more or less united, so as to assimilate the bordering to that of the male, but in such 

 case the interior border of the black markings is powdery, while it is well defined in the 

 male; fringe in general the same as in the fore wings, but. in the subcostal area, the 

 outer half is jiale yellow, interruiHed narrowly at the nervule tips with ferrugineo- 

 roseate. 



Beneath slightly duller than the upper surface, tlie inner border of the hind 

 wings whitish; the upper half of the fore wings very sparsely, the whole of the 

 hind wings sparsely, ornamented with rather dark brown scales clustered, on the 

 hind wings, into more or less distinct, but always powdery spots, which are often ac- 

 companied by pale scales and surrounded by yellow oues, slightly tinged with orange; 

 they are transversely placed and situated a little beyond the middle of the lo'.ver sub- 

 costal, the median and medio-subraedian interspaces and a little before the middle of 

 the subcosto-median interspace; the extremities of the nervules in each wing are 

 tipped with black and the upper outer angle of the cell has a minute, blackish, roundish 

 spot; on the hind wings there is also a minute cluster of black scales just above the 

 costal nervure, close to the base, another as near its tip and just beneath the latter, 

 on the succeeding interspace, is a slight transverse cluster of blackish scales ; directly 

 beneath the tip of the upper subcostal nervule of the hind wings and crossing the 

 upper and a portion of the succeeding subcostal interspace is a large roundish spot, 

 occasionally reduced nearly to a dot. of a reddish chocolate color, only the upper outer 

 border of which touches the border and the centre of which is enlivened with pale 

 roseate scales ; the costal border of the fore wings and the outer border of both is red- 

 disli orange, including, between it and the fringe, the black spots at the nervule tips ; 

 the extreme base of the fringe and the costal edge are gray and the outer portion of 

 the fringe ferrugineo-orange, excepting on the subcostal area of the hind wings, where 

 it is greenish yellow, tipped with ferrugineo-roseate, and on the inner margin, where 

 it is yellowish. 



Abdomen above blackish brown, on the sides bright yellow, with occasional brown- 

 ish scales and particularly with a broken lateral line of dark scales ; beneath white, 

 tinged occasionally with yellow. Upper organ of male appendages (35 : 11-13) curved 

 downward, its point reaching the middle of the lower border of the clasps, about
