1336 THE BUTTERFLIES OF NEW ENGLAND. 



base below the costal vein l)lack ; this stripe is in continuation of the oblique series of 

 spots crossing the middle of the fore wing. In continuation of the lower and outer 

 series of the same wing there is an arcuate series of very large and deep yellow 

 lunulcs, snbparallel to and distant from the outer margin, one to each interspace, the 

 innermost with its form destroyed and its size vastly reduced by the deep emargina- 

 tiou of the inner margin ; they are subequal in size and about as large as the average 

 of those of the gre?t transverse series of the fore wings ; the lowest subcostal and 

 the median spots occupy about the middle of their respective interspaces ; the others 

 are nearly in a straight line witli these, excepting the uppermost, which is removed in- 

 ward l)y nearly its own width. Jnst before tlie emargination of the inner margin, and 

 following the excised spot of the medio-submedian interspace is a velvety black, trans- 

 verse bar, which scarcely reaches the lower median nervule, followed interiorly by a 

 broad, orange red hinule, of similar size and somewhat similar shape, embracing it ex- 

 teriorly, again followed by a velvety black lunule, sprinkled to a greater or less 

 exent with caerulean bine. A large yellow oval spot, attenuated interiorly and divided 

 to a greater or less extent liy the upper median nervule into unequal parts, the upper 

 the larger, is found just before the tip of the spatulate tail. The outer margin is in- 

 terrupted with yellow Innules in all the interspaces, whicli include the fringe, other- 

 wise black. 



Beneath mainly yellow, not so bright andclear as above, but more nearly clay-yellow, 

 with a greenish tinge where the reverse is black. Fore wings with mucli tlie same 

 markings as above but mucli enlarged and extended, and to some extent combined. 

 The main transverse series is much larger, and in the upper half of the wing combines 

 witli that depending from the costa at the apex of the cell, so as to cover all the inter- 

 vening space, the spots merely separated by the black veins. The series at the lower 

 outer corner of the wing becomes developed into a submarginal series, the spots found 

 in every interspace fully opening on the outer margin, separated from each other by 

 little more than the black veins, the outer border of tlie series sul)parallel, and, 

 especially above, less than half an interspace distant from the outer margin, its upper- 

 most spot larger and clearer than those next below, being the counterpart of the 

 apical spot of the great transverse series of the upper surface, which is here trans- 

 ferred to the marginal series; with this exception, the spots diminish very regu- 

 larly in size on either side of the second median interspace. Within the great 

 transverse belt, especially away from the veins, the whole base of the wings is 

 heavily powdered with yellow, giving a greenish gray, longitudinally streaked 

 appearance to the cell. Margin and fringe interrupted with yellow, as above, but 

 more deeply. Hind wings almost entirely yellow, including even the veins on the 

 basal half of the wing. Across the midille of tlie wing is an arcuate band, con- 

 sisting of a confluent series of strongly arcuate, outward facing lunules, strongly 

 attenuated at the nervules, bent at a broad angle at the middle lunule, that in 

 the second subcostal interspace usually occupying, but sometimes failing to reach, the 

 extreme base of the interspace, the upper occupying the reverse of the black interval 

 on the upper surface, the lowermost, the medio-submedian interspace just before the 

 emargination ; each includes a powdery lunule of similar arcuation, but genei'ally very 

 slender, of caerulean blue, sometimes tempered with brown, especially next the nerv- 

 ules, and the lowest also includes, just before its outer extremity, a large transverse, 

 rounded orange bar, yellow next the lowest median nervule, and then continuous with 

 the outer yellow, this orange bar corresponding to that of the upper surface. Just 

 before the end of the cell, separated from the vein connecting the subcostal and 

 median nervures by a slender streak of yellow, is a bent and rather narrow black bar, 

 occasionally flecked next its outer margin with a line of caerulean blue. The base of 

 the upper two median interspaces, and to a slight extent, generally, the lower subcostal 

 interspace are heavily flecked with rusty orange. On the margin, the yellow lunules 

 of the interspaces on the upper side are enlarged, leaving between them and the yellow 

 apical ground of the wing only a narrow series of transverse lilack lunules or arcuate 

 black bars, touching the margin and including the fringe only at the nervure tips ;
