THE BUTTKRFLIKS OF NEW ENGLAND. 



wliich are always fouml bordering the nervules. The iuiier margin, as far as the sub- 

 median nervure. and often near its tip, a little way beyond it, is pale lemon yellow; 

 fringe greenish yellow, tipped with fuscous below the lower median nervule. 



Beneath : fure wings very pale orange, often tinged with dark greenish yellow along 

 the basal half of the costal border; andwith lighter yellow along the outer half and on 

 the outer border; this portion, and especially the apex, is streaked faintly with 

 short, delicate, transverse, rather infrequent lines of dusky or ferruginous scales ; 

 a small, dusky spot, sometimes obsolete, in the middle of the lowest subcostal and an- 

 other in the middle of the subcosto-median interspace, and, occasionally, less distinct 

 ones, in the median interspaces, at two-thirds tlie distance from the tip of the cell to 

 the outer margin ; the spot of the upper surface at the ape.^i of the cell is repeated, 

 less distinctly, beneath; the tips of all the nervules, except the submedian, are marked 

 with black ; fringe ferrugineo-orange, interrupted rather broadly with faint dusky at the 

 nervule tips; costal edge blackish at base. Hind wings greenish yellow, occasionally 

 tinged slightly with orange, the whole surface enlivened by short, delicate, irregular, 

 wavy, transverse streaks of mingled fusco-ferrnginous and dull orange scales, clus- 

 tered across the middle of the wing, either into an irregular, broken, vague, slender 

 stripe ((?) ; or, into a similarly irregular, broken, blurred, broader band (?), crossing 

 the costo-subcosta! interspace just above the termination of the curve of the upper 

 subcostal nervule, in the subcostal interspace following the direction of the interior 

 margin of the black border of the upper surface of the male, but extending to the 

 apex of the cell ; it crosses the middle of the median interspace, and the medio-sub- 

 median interspace at its middle, or in broken continuity with the subcostal portion ; in 

 the female only, in the basal half of the subcostal and median interspaces, and some- 

 times, to a .slight extent, just within the streak in the costo-subcostal and medio-sub- 

 median interspaces, the yellow scales of the ground are supplanted by dingy white 

 scales; in both sexes, where the dusky streaks touch the costal border they become 

 blackish and there is a blackish dot at the tip of each nervule, at the divarication of 

 the subcostal nervure. and sometimes in the median interspaces in the middle of the 

 stripe, which is here usually reduced to spots; fringe as on the upper surface.* 



Abdomen above black, sprinkled with a few greenish yellow scales and at tlie base 

 with similarly colored hairs ; sides greenish yellow, the lateral line with a few dusky 

 scales at the tips of the segments, and just beneath it tinged witli orange; under sur- 

 face a little paler than the sides. Upper organ of male (35 : 7-9) with the hook scarcely 

 more than half as long as the centrum, reaching as far as the clasps — the latter much 

 broader than long, furnished interiorly close to the tip with three similar laminate 

 tooth-like serrations, fully twice as long as broad, incurved, two following each other 

 in a curving plane, which from being vertical and directed backward inclines horizon- 

 tally and inward, the third a little within the lower of the other two, directed more 

 strongly inward than it and depressed ; tliere is also a rectangularly toothed lamina 

 below the middle of the upper margin. 



Described from 7 J , 8 $ . 



* In two females, locality unknown, the 

 under surface of the wings has a very difl'er- 

 ent general aspect, being almost altogether dull 

 ferruginous ; this appearance is due to the pre- 

 dominance of certain features, the wing being 

 wholly dingy white, tinged with yellowish, 

 but almost entirely overpowered by the cross 



streaks, which are almost exclusively ferru'_ 

 ginous, butwirh a dull orange tinge; they are 

 also more compact along the middle stripe, 

 which latter becomes conspicuous almost 

 solely by the absence of any mottling above 

 it, corresponding to the pale portions iu other 

 females.
