522 THE BUTTERFLIES OF NEW ENGLAND. 



blue, giving it a hoary aspect (sometimes reacliing aci'oss tlie mesial band to tlieintra- 

 mesial stripe) extending on the costal border from midway between the tips of the 

 second and third superior branches of the subcostal to the mesial band, and to the 

 middle of the outer four-flfths of the lowest subcostal nervule, its outer limit well 

 defined and nearly straight; Avhen, as occasionally, it includes the upper portion of the 

 mesial band, it extends downward to the upper median nervule. Midway between this 

 and the outer border, there is usually another vaguely defined whitish spot occupying 

 the whole width of the lowest subcostal interspace, sometimes shading oft' vei'y gi'adu- 

 ally toward the tip of the wing, which is generally of an ochraceous hue and between which 

 and the triangular silvery spot is a f usco-f ulvous stripe, often tinged with olivaceous, 

 broadening dowmvard, extending from the costal border to the lowest subcostal nervule ; 

 the same color is repeated next the outer border in the subcosto-median and upper 

 median interspaces, limited inwai-d by a dark fuscous, slender, submarginal stripe, less 

 than an interspace's distance fi'om the outer border, and Avhich reaches nearly to the 

 inner bordei*. In the median area the outer half of the wing is fulvous, not so deeply 

 tinged with orange at the base, and, corresponding to those of theupper surface, are 

 three roundish black spots in the median and medio-submedian interspaces ; a blackish 

 fuscous line traces the limit of the outer border; fringe blackish brown, interrupted 

 rather broadly with dirty pale yellowish in the interspaces. Hind ivings luteo-tawny 

 upon the basal two-fifths, strongly enlivened with dark brownish feri'uginous, espec- 

 ially in the upper outer half of the area, collected to a considerable extent into minute 

 blotches or flecks and besprinkled lightly with blackish and silvery Avhite scales, the 

 former in the upper, the latter in the lower half of the wing ; in the upper half of the 

 wing the basal colors are distinctly limited, the line of demarcation following that of 

 the infra-mesial stripe of the upper surface, excepting in tlie subcosto-median inter- 

 space, where it is removed considerably towards the base, and crosses the cell in a strong 

 curve, opening inwards, whose outer limit does not reach the middle of the vein clos- 

 ing the cell ; in the costo-subcostal interspace there is a strongly curved, transverse streak 

 of white, or grayish white, usually enlarged considerably at either extremity, its lower 

 end resting on the first divarication of the subcostal; and in the medio-submedian, 

 next to the first divarication of the median, a transverse, often bent, black streak, be- 

 tween which and the limitation of the basal color (which in this part of the wing is 

 marked by an independent though faint, intra-mesial, blackish streak) the color is paler 

 frequently forming a broad pale band extending nearly to the inner border; the costal 

 margin is traversed throughout its length by delicate transverse streaks of black- 

 ish brown ; beyond the basal two-fifths is a very broad mesial band similar to that 

 of the upper surface, but usually broader, of silvery or grayish white above the sub- 

 costal nervure, below it pale brownish white, more or less flecked with very short, 

 minute, transverse streaks of blackish and ferruginous, generally more frequent on the 

 outer half; the outer border is broadly bordered with hoary, flecked somewhat with 

 dark brown, averaging fully half an interspace in width, but tapering to a point at the 

 costal and submedian nervures ; the inner border is not regular, but mounts inward 

 above and upon the lower two subcostal and upper median nervules ; between this bor- 

 der and the mesial band is a broad band of f usco-f erruginous, or dark fulvous, 

 deepest in color above, and flecked minutely with transverse blackish lines, and en- 

 closing in the middle of the lower subcostal and the median interspaces roundish 

 blackish spots half as broad as the interspaces with a faint, minute, whitish pupil ; fringe 

 pale dirty yellow, interrupted rather broadly at the interspaces with blackish fuscous. 

 Abdomen above blackish brown, largely sprinkled on the sides and apical half of 

 upper surface with fulvous scales; beneath dirty, grayish, often yellowish white. 

 Male appendages (33 : 37) : upper organ with the centrum only half as long as broad, 

 longitudinally channelled a little on either side of the middle; hook fully' as long as 

 the centrum, beyond the basal third as broad as high, straight; clasps apparently 

 formed of two longitudinal pieces, the upper, bearing the recurved hook, being sinuous, 

 of nearly equal breadth throughout, and less than half as broad as the clasp proper ; the 

 recurved hook is small, bent backward at a right angle and a little inward, and bears four
