886 THE BUTTERFLIES OF NEW ENGLAND. 



or quite concealed by siio-vv white scales ; tibiae similar, Init alrove more or less tlecked 

 with blackisli and having always a subapical dark patcli aud sometimes a patch in the 

 middle of the basal half; tlie dark colors are most conspicuous on tlic liinil tibiae; 

 tarsi bright Inteous beneath, above black, narrowly ainiulate with white at the apices 

 of the joints aud In'oadly in tlic middle of the basal joint; spines black; claws dark 

 reddish, brighter at base. 



Wings above uniform dark glossy, almost blackish brown, with the slightest possi- 

 ble olivaceous reflection, the veins and outer edges blackish ; the hind wings softer 

 from the presence of numerous greenish gray hairs on the lower half; basal half of 

 costal edge of fore wings fulvous; hind wings fre()uently ( $ ) or almost never ((J) 

 possessing in the lower median interspace a small, submarginal orange patch, seated 

 on a blackish spot and in the next lower interspace a few orange scales ; outer border 

 of hind wings in the same interspaces with a delicate line of pearly white scales 

 seated njion the blackish edging of the whole wing; fringe of both wings light yel- 

 lowish gray, blackish at base, excepting on the lower half of the hind wings, where 

 between the tails, the fringe is pearly white, sometimes obscured with gray, blackish 

 at base; below the lower tail it is blackish, narrowly pearly white at base; tails 

 black-tipped, the longer fringed on the inner border with pearly white; there is a 

 small patch of white scales at the excision of the inner margin, beneath which the 

 fringe is blackish brown. Discal stigma (44:1) of the fore vvings of the male 

 rounded obovate, nearly twice as long as broad, slightly darker than the ground color. 

 Tlie portion of the sulicostal nervure of the fore wings (61 : 5) of the male which 

 lies on either side of the second superior nervule curves strongly downward a little 

 beyond the middle of the cell ; the vein connecting the inferior nervules to the main 

 stem not transverse, but oblique; in these respects this species approaches P. Onta- 

 rio rather than its other congeners, but is not greatly different from T. liparops. Outer 

 margin of the hind wings above tlie longer tail nearly straight, the longer tail more 

 than half as long again as the width of an interspace, the shorter very slight. 



Beneath uniform blackish slate brown {S) or dark slate brown (?), old specimens 

 inclining to an ashy lute. Fore iBimjs with the extremity of the cell covered by a sub- 

 quadrate slightly darker spot, usually widest above, the outer and inner borders edged 

 with bluish pearly scales; the middle of the outer half of the wing is crossed by a 

 moderately broad stripe of confluent quadrate spots, slightly darker than the ground 

 color of the wing, and darkest next tlie outer border, distinctly bordered externally 

 and frequently (J) or almost never {$) very faintly upon the inner side with bluish 

 pearly scales ; the whitish external lining of each spot is usually more or less curved, 

 opening inward, but is not infrequently straight; the direction of the band varies 

 greatly ; its general course is : starting from a point close to but not upon the costal 

 border at about the middle of its outer half, it passes in a rather regular and slight 

 curve towaril the inner margin, gradually approaching the outer margin, as far as the 

 lower median uervule and then turns inward again very slightly, aud terminates at 

 the submedian nervure, at about two-thirds the distance from the lower outer angle 

 that its origin had from the upper outer angle of the wing; usually, however, it is 

 abruptly, though but slightly, broken at the upper median nervule, being removed 

 inward slightly at this point ; the same thing usually occurs also at the lower median 

 nervule; yet the band not infrequently continues on its course at this point and 

 reaches still nearer the outer border at its very termination; occasionally the upper 

 extremity of the l)and is bent abruptly' inward or outward and, linally, the spots may 

 be so related that the outer white edging forms either a nearly continuous, gradually 

 curving line, or a series of little curves, or a series of dentations or steps, the angle 

 not in the middle but at the lower corner of each spot; the width of the band also 

 varies, in some being three or four times as wide as in otliers; usually it is about the 

 width of the eye; it varies but little in general location, although iu a few extreme 

 specimens before me, it varies from the middle of the outer third to the middle of the 

 outer two-thirds of the wing. Outside of this is a submarginal line of nearly or 

 quite connected, delicate, transverse, l)lackish streaks, edged internally with white
