In the lower submeil inn iiitorspjioc, ami partiiiUy so in a sorics of obscnre marginal 

 spots; frequently the lioary iiiarkinjrs of the posterior half of thewinjr are limiteil by 

 a nearly straight line, formed by the lower half of the outer margin of the broad 

 band and its continuation; outer edge marl<ed by a line of dark reddish brown scales; 

 basal half of the fringe reddish brown, apical half dull white, interrupted at the norv- 

 ures with l)lackisli brown. 



Abdomen covered above with purplish l)lack and rich deep brown scales, on the 

 sides with tiie same, but with fre<|Uently interspersed pale l)rown and wintish scales; 

 beneath grayish white, brownish toward tip; outer edge of .alations of upper organ of 

 male (34:22) almost straiglit, the inferior lobe inconspicuous, broadly roundcil ; 

 clasps slenderer than In the other species, and tapering regularly. 



Variations. One specimen from Xorway, Me. (No. 1527, Mus. Yale Coll., S. I. 

 Smith) ditlers from the norm in wanting the excessive prolongation of the scales at tlie 

 tip of the nervures of the hind wings, and in having the male discal spot of the fore 

 wings small and scarcely more than twice as long as broad; the outer margin of the 

 fore wings is also narrowly hoary, similar in color to the border of the hind wings. 

 This same combination of characters is also found in a male from Needham, Mass. 

 (taken as early as April 28), which Mr. Whitney has shown me. Two females, one from 

 an unknown locality, taken May 12 (Whitney), and the other taken in Walpole, Mass. 

 (Miss Guild), have equally entire wings and hoary edged fore wings, and the former 

 has also the upper surface of the wings distinctly tinged with olivaceous. Although 

 these characters seem to be thus correllated, they cannot be deemed of more than 

 incidental value, for a male from Middleboro, Mass. (Hambly), which possesses the 

 short sexual dash, has at the same time hind wings which are distinctly tailed and 

 fore wings without hoary scales ; so too a specimen from Altjany, N. Y. (Liutner) has 

 the principal tail of the hind wings only half as broad and twice as long as usual. 



.\ female from Albany sent me by Mr. Lintncr difl'ers from ordinary specimens sim- 

 ply in a greater straightness of the extra-mesial stripe on under surface of tlie fore 

 wings, and in tlietint of the color beyond the stripe on both wings; it has a decidedly 

 olivaceous hue ; but another specimen from same locality stands in both these respects 

 midway between this form and the typical irus. They illustrate an extreme of col- 

 oration in a special direction, curiously accompanied by a more than usual straightness 

 of the extra-mesial line of the fore wing beneath. In every other particular it Is 

 perfectly matched by other specimens. 



Suffused variety. Inxis. lUfs bai.tk.M'.v. A suffused specimen taken in Centre, 

 near Albany in May 1S7G Ijy W. W. Ilill, was sent me by Mr. .1. A. Lintner. It is a female ; 

 above there is nothing peculiar about it excepting that the color is unusually dark (like 

 other specimens I haveseen from Centre) ; beneath the lilaceous powdering of the mar- 

 gin of the wing is wanting, as if to give intensity to the suffusion of the other parts, 

 which is brought about in this way : the row of roundish dark spots, normally situated 

 on the fore wing, half way from the irregular extra-mesial band to the border, and on 

 the hind wing, one-quarter way from the corresponding mesial band to the border, is 

 present, the spots a little diffused ; the darkest portion of the irregular band is also 

 present as a series of similar spots and between them the whole space is occupied by a 

 powdering of lilaceous or hoary scales, being the diffusion of the white portion o{ 

 said band broken more or less distinctly into spots by the dusky nervures ; on the hind 

 wings the inner band is lost, as' it frequently is in otherxvise unsuffused specimens, in 

 cloudy hoary patches over the base; while midway between the suffused hoary belt 

 just described and the margin of the wing is another broader, cloudy belt of hoary
