1460 THE BUTTERFLIES OF NEW ENGLAND. 



lowed exteriorly by pale clots or spots, occasionally by delicate, very short, pale lines 

 uniting them to the outer border, which is edged with blackish. Fringe nearly uuif orm 

 dark grayish brown , the basal portion flecked with hoary scales. Hind xoinys very nearly 

 uniform, soft, blackish brown, tending to fuliginous ; a marginal and extra-mesial row 

 of spots, the latter in the middle of the outer two-flfths of the wing, are distinct only 

 in the 9 tind there consist of small, roundish, pale cinereous spots, occasionally arrow- 

 headed, the extra-mesial row sinuous; in the (J they are sometimes entii'ely obsolete, 

 or the marginal series when present is quite inconspicuous ; outer border edged with 

 black as in the fore wings ; fringe dark cinereous, a little lighter than on the fore wings, 

 duskier toward the base, at extreme tip, especially above, a little whitish. 



Beneath dark fuliginous brown, with a slight purplish tinge. Fore loings very pale 

 ochraceous or cinereous along the inner margin, fading out on the adjacent parts. The 

 vitreous spots exactly repeated beneath ; outer portion of the wing with two trans- 

 verse rows of very pale ochraceous or whitish spots, the outer composed of smaller, 

 usually more distinct and whiter, marginal spots, dots, or rarely short longitudinal lines, 

 occasionally obsolete In the J ; the inner of short, longitudinal, cloudier, pale dashes In 

 the middle of the outer two-fifths of the wing, fainter in the $ than in the ? , and in the 

 former occasionally obsolescent; the spots of both rows increase in size in approach- 

 ing the inner border, and finally merge in the pale field of this portion of the wing ; the 

 extreme apex of the wing is more or less heavily flecked with grayish or hoary scales, 

 generally extending a little on the fringe of this part of the wing ; outer margin edged 

 with black; fringe slightly grayer than the ground color of the wing, faintly paler at 

 the extreme base. Hind loings with a double row of always small, pale ochraceous 

 spots, more distinct and larger in the ? than in the $ , and in the latter of ten obsoles- 

 cent; the outer are seated on the border and are usually reduced to short longitudinal 

 lines in the middle of the interspaces ; the latter form a slightly sinuous row in the 

 middle of the outer two-fifths of the wing, and although sometimes roundish, are very 

 often, even in the ? , reduced to lines like those of the marginal series or even shorter ; 

 and when roundish are usually more intense along the middle. Outer margin and 

 fringe as in the fore wings. 



Abdomen above blackish brown, the tips of the segments grayish; beneath flecked 

 with brownish gray. Male appendages (36 : 4-G) with the upper organ very similar to 

 that of N. persius, differing in being shorter, having shorter terminal hooks; a larger 

 proportion of the cup, forming the union of the lateral arms, seems to be covered 

 with the inferior armature, as it extends almost to the base of the bent portion of the 

 arms. Left cJasp : Main body pretty small, slender, straight, slightly convex laterally, 

 increasing rapidly and pretty regularly from the base, foi*ming a high triangle, whose 

 apex is at the base of the piece. Blade pretty broad at the base and directed a little 

 downward, decreasing rapidly in size, and then unifonnly slender, very long, curved 

 backward, slightly upward and considerably and regularly inward, scarcely com- 

 pressed. Its outer surface twisted slightly in the apical half so as to become nearly 

 horizontal and uppermost, very bluntly rounded at the tip, the upper inner angle a 

 little produced; basal process digitate, attenuated, incurved, bowed upward, not com- 

 pressed, slenderest at the base, rounded at tips, a little more than one-third as long as 

 the blade. Lobe forming a slightly longer, broad, nearly equal, flattened plate, a very 

 little narrower and very broadly rounded at the tip, curved slightly inward and twisted 

 a very little, tending to bring the outer surface uppermost. Sight clasp : Main body 

 like that of the opposite side. Blade similar in size, length, form and direction 

 to the left clasp, but not so broad at the base, equally rounded at the tip and aimed 

 apically with a very few minute, inconspicuous spinules; basal process reduced to a 

 slight, pointed, triangular tooth, connected with the blade by a slight ridge. Lobe 

 very large and broad, reaching downward beyond the base of the blade, fully half as 

 long as it, rounded at tip, directed backward and a little upward, gibbous, curved 

 inwird a little more than the blade, the tip bent suddenly upon itself and directed 

 straight forward, the bent apex and incurved lower edge armed, the former with a few 

 very long, the latter witli more frequent shorter, minute spinules.
