876 THE BUTTERFLIES OF NEW ENGLAND. 



same interspace, and, usually, to a lesser extent, in the succeeding interspaces, and 

 also in the upper median interspace, there is an orange lunule. seated, at least in the 

 lower median interspace, upon a small blackish spot. Basal half of fringe fuscous ; 

 apical half in the fore wings and in the subcostal and median field of the hind wings 

 grayish pearly ; beyond this fuscous or nacreofuscous, with a pale median line; tails 

 black, tipped, and the inner edge of the longest one bordered, with white ; inner field of 

 hind wings obscured by grayish hairs. In the male the origin of the second superior 

 subcostal nervule is scarcely removed beyond the first and is midway between it and 

 the third, the last being scarcely a fourth way from the origin of the first to the tip 

 of the cell ; beyond the origin of the third the main vein turns abruptly downward 

 nearly at right angles a fifth way across the cell, and then as abruptly resumes a 

 course parallel to the last superior branch. The upper half of the vein closing the 

 cell is here most remarkable, being not only distinct throughout the whole of its upper 

 half but bent at right angles, one branch continuous with the deflection of the main 

 stem, the other, excepting a slight twist at the union, with that of the inferior branch; 

 below, the inferior branch is connected with the median by a feeble vein which strikes 

 the median normally beyond its last divarication, but the inferior branch opposite the 

 twist which unites it with its bent cross vein, normally of course, but apparently 

 quite out of place. In this peculiarity of neuration it is quite unique among Theclae. 



Discal dash of fore wings of male 2.5 mm. long, obovate, the ends well rounded, 

 slightly more than twice as long as broad, grayish slaty black in color, conspicuous 

 from its edging of black scales. The outer margin of the hind wings above the 

 longer tail straight, the latter about as long as the width of an interspace, the shorter 

 tail almost obsolete. 



Beneath uniform slate brown, lustrous by reflection. Fore loings with a slender, 

 interruptedly straight, scarcely curved, transverse, silvery white stripe, bordered 

 interiorly with blackish fuscous, starting from just within the costal border at about 

 the middle of its apical three-fifths and terminating at the submediannervure, distant 

 from the outer border by less than twice the width of an interspace ; beyond this is a 

 transverse series of continuous, moderately broad, submarginal stripes of obscure 

 fuscous, parallel to the margin, becoming obsolete near the costal margin, bordered 

 most inconspicuously on the inner side with a few white scales ; costal edge fulvous 

 nearly to the extremity. Hind ivings with an extra-mesial stripe similar to that of the 

 fore wings, but more interrupted and, in the lower part of its course, variable in direc- 

 tion ; starting from the costal border at about the middle of its apical three-fifths. It 

 has, up to the lower median nervule, a general direction toward the tip of the sub- 

 median nervure, but an outward curve in the subcosto-median interspace; in the 

 medio-submedian interspace it forms a ^, the limbs placed at an angle of about 65° to 

 each other; and as it terminates in the last interspace by a long, slightly curving 

 streak whose general direction is parallel to the upper half of the A' the portion of 

 the stripe contained in the last three interspaces forms a very distinct W ; a distantly 

 submarginal series of blackish lunules follows this stripe, growing successively more 

 important away from the costal border and arranged only in a slight degree subpar- 

 allel to the hind margin ; the lunules are edged interiorly with pale bluish scales, most 

 conspicuous next the inner margin, and are followed exteriorly, especially in the median 

 interspaces and below them, by orange lunules, seated, especially in the lower median 

 and lowermost interspaces, upon blackish spots ; in the latter, separated from them, 

 next the inner margin, by aminute snow white spot ; the medio-submedian interspace is 

 mostly filled with a large, blackish field, profusely flecked with caerulcan scales; 

 outer border marked by a blackish line, preceded by a pale line, brightening on the 

 lower portion into white ; fringe and tails as on the upper surface. 



Abdomen above blackish brown, on the sides paler brown, beneath grayish hoary. 

 .Vppendages of the male (34 : 15) with the alations of the upper organ broadly, deeply, 

 and roundly emarginate above, the lateral arms exceptionally long and slender, sud- 

 denly tapering near the tip ; clasps tapering throughout with considerable regularity, 

 but with slightly less rapidity beyond the gibbous base, the apex very finely pointed.
