1608 THE BUTTERFLIES OF NEW ENGLAND. 



Fore wing (42 :7) nearly twice as long as broad ; the male sometimes a little longer; 

 the lower outer angle falling a little beyond the middle of tlie costal margin, costal 

 margin straight; outer margin regularly rounded, tlie tip only a little, in some males 

 distinctly, produced. Costal nervure terminating considerably beyond tlie middle of 

 the costal margin ; subcostal nervure moderately distant from the costal margin, the 

 second nervule arising from the middle of the wing; the cell two-thirds the length of 

 the wing, slender, subequal in the apical half ; first median nervule arising midway 

 between the base and the second, the second beyond the origin of the second subcostal 

 nervule ; internal nervure short, terminating in the submedian. 



Hind wing rounded, triangular, a little longer than broad ; the costal margin be- 

 yond the strong basal lobe straight; outer margin as in Phycanassa. Subcostal and 

 first median nervules arising at similar distances from the base and scarcely beyond 

 the basal third of the wing. 



Legs 2, 3, 1; femora clothed as in Poanes; hind tibiae with a very thin fringe of 

 hairs on the basal half and all the tibiae armed above with minute, distant spines, 

 those of the fore tibiae inconspicuous. Femora 2, ci, 1, sometimes the hind femora 

 scarcely so long as the fore; tibiae 2, 3, 1, the middle sometimes slightly longer than 

 the hind pair; tarsi 2, 3, 1; fore and hind femora more than two-thirds the length of 

 the middle femora and scarcely shorter than tlie hind tibiae. Fore tibiae scarcely 

 two-thirds the length of the fore femora and more than half the length of the 

 middle or hind tibiae. Leaf-lilie appendage of the fore tibiae small, slender, 

 originating in the middle of the outer two-thirds of tlie joint, scarcely, if at all, 

 surpassing its extremity, about five times as long as broad, nearly straight, 

 tapering toward the pointed tip ; other tibiae with an apical pair of very long 

 and slender spurs ; and the hind tibiae with a similar but slightly shorter pair 

 in the middle of the apical two-thirds. Tarsal joints 1, 2, 3, 4, 5, the apical joint 

 slightly longer than the penultimate on the fore legs ; fore tarsi fully two-thirds the 

 length of the middle and hind tarsi, of the length of the middle femora; all 

 armed beneath with a triple series of long and slender spines, the apical ones of 

 each joint much longer than the others ; basal joint as long as the following three 

 or four joints together, the second about half the length of the first. Claws small, 

 slender, tapering, strongly and regularly curved and finely pointed. Pad small, trans- 

 verse. Paronychia bifid, the upper lateral, laminate, triangular, straight, as long as 

 broad and only extending half way to the tip of the claw ; the lower as far toward the 

 bottom as possible, nearly as large as the apical half of the claw and curving in an 

 opposite direction; in one extra New England species, however, the lateral branch is 

 lanceolate, as long as the claw and curving slightly in the same direction. 



Second abdominal segment half as long again as the first, a little longer than the 

 third ; beyond, the segments decrease regularly, the eighth as long as the sixth, but not 

 extending down the sides as the seventh, entire. Upper organ of male appendages 

 small, reaching as far as the clasps, very strongly arched, tapering from the base 

 apically, or broadening just beyond the base and then tapering, depressed, the hook 

 shorter than the centrum, double, but the two halves so closely compressed as often to 

 appear as if one, depressed, tapering pretty regularly; lateral arms forming a 

 single, moderately stout, conical piece, directly horizontally backward, some- 

 times in conjunction with the hook, sometimes below it. Clasps large, very 

 broad, less than twice as long as broad, the greater portion equal and straight 

 but slightly convex, the extremity variously armed by projections from the upper 

 and lower angle, the upper sometimes nearly obsolete, always smaller, the lower 

 rather broad, upturned. 



Egg. Pretty high, broadest at the base, narrowing rather rapidly and regularly, the 

 top broadly but not greatly flattened ; surface broken up by very slightly raised lines 

 into polygonal, usually elongated, hexagonal cells, and so suboval in appearance. 

 Micropyle consisting of a minute central circle, bordered by four divergent canals, 

 surrounded by six or eight rounded, kite-shaped cells, twice as long as broad, sur- 

 rounded again by a mass of nearly circular, polygonal cells.
