364 THE BUTTERFLIES OF NEW ENGLAND. 



the nervule ; the outer border is sometimes faintly enlivened with scattered pale, ochra- 

 ceous or tawuy scales, and the fringe is blackish, broadly interrupted with the same 

 colors, but mainly with white. Occasionally the edge of the wing has a slight hoary 

 bloom, as in the previous species. 



Hind vnngs (61 : 23, 24) with the outer border a little crenulate, the tail of the upper 

 median nervule either very broad at base, almost triangular (1-argenteum) or broad 

 and gently tapering, the tip broadly rounded (c-argenteum), the projection at the tip 

 of the upper subcostal nervule slight, angulated, that at the lower angle small and 

 rounded. Color of the tint of the base of the fore wings, the outer border, as there, 

 margined broadly with black, but also reaching further toward the base, and becoming 

 more or less gradually mixed with ferruginous, until the boundary between it and the 

 orange is mai'ked, about midway between the first divarication of the subcostal and the 

 outer border, by a multitude of short, transverse threads of ferruginous on an oi-ange 

 ground, becoming less and less frequent interiorly but seldom reaching so far as the 

 last divarication of the median uervure ; within the apical area and marking the limit of 

 the outer edging of black, which can seldom otherwise be noted, is a series of very 

 small, roundish, dull ochreous spots subparallel to the outer border. The basal half 

 of the costal border, as far as the subcostal nervure, is wholly brownish fuscous, deep- 

 ening into blackish at its outer limit, just below which in the upper subcostal inter- 

 space and generally crossing it is a smaller black spot, removed generally by more 

 than its own diameter from the base of the interspace ; the upper half of the nervule 

 closing the cell is marked more or less heavily with black, which, when it is broadest, 

 extends also over the base of the nervule above; the outer border is edged, much 

 more frequently than on the fore wing, with a hoary bloom ; fringe blackish fuscous 

 at the nervule tips, dull ferruginous elsewhere, but occasionally interrupted with 

 white in the middle of the interspaces and not infrequently almost wholly concealed 

 by the hoary bloom. 



Beneath gray, the basal lialf brownish, the apical half dull ashen, the line of demar- 

 cation on the fore vnngs being sharply defined, passing from about the tip of the costal 

 nervure to the median nervure just beyond the tip of cell, crossing next the upper 

 median interspace by a line subparallel to that which strikes the upper median nervule 

 at the base of its straight portion ; then crossing the lower median interspace l)y a similar 

 line, whose origin on the middle median nervule is midway between the base of the 

 nervule and the point where the line in the upper median interspace strikes it ; and 

 finally the interspaces below, still a little further removed toward the base ; the darker 

 parts of this basal field are toward the outer limits where they form an indistinct 

 band of about the width of an interspace, while within this straight threads of pale 

 scales, subparallel to the lower half of the outer border of the basal half of the wing, 

 and enclosing slender stripes of slightly varying depths of brown, variegate the wliole 

 base of the wing ; in particular there crosses the cell one stripe of a plumbeous color, 

 narrowly e<lged with black and this again faintly with pale, extending from the base 

 of the subcostal nervule to the median nervure just beyond the base, the homologue 

 of the two distinct spots of the other species of Polygonia described in this work ; on 

 either side of it the upper half of the cell is slightly ashen; the costal edge is marmo- 

 rated as above but more interruptedly ; excepting next the outer border the outer half 

 of the wing is gray with short, transverse threads of blackish and fuscous, some- 

 times commingled to form slender streaks, upon an ashen surface more or less 

 tinged with yellowish brown ; above the lower subcostal nervule, however (excepting a 

 narrow band next the middle of the wing), the outer half is more or less clouded with 

 grayish ashen which extends to the outer mai-gin of the wing ; below the first superior 

 subcostal nervule the outer border is broadly bordered to nearly the depth of an inter- 

 space's width with a color as deep as the base of the wing but more or less enlivened 

 with pale or ochreous scales, limited interiorly by a strongly zigzag black line or series 

 of connected sagittate spots, enclosing slenderer lunules of dull metallic greenish ; 

 these black sagittae are continued in the ashen tip by small, blackish dots, that of the 

 apical subcostal interspace in the middle of its outer two-thirds ; it is succeeded in-
