form open. The subterminal grey dentate shade is paler than in its 

 ally, more obvious and deeply dentate and bent opposite the teeth of 

 the t. p. line; the succeeding dusky shade in C. obscura is here ob- 

 solete. There is a distinct, diffuse, subapical, oblique, blackish shade 

 (wanting in C. obscura), which dentatedly margins the subterminal 

 pale shade opposite the discal teeth of the t. p. line. Terminal field 

 less dusky than the rest of the wing. Hind wings black, with dusky 

 fringes, becoming white at apices. Beneath similar to C. obscura ; 

 the fringes on both wings dusky, the white bands quite narrow. 



Expanse, 74 mm. 



Hab. New York (in Coll. Buf. Soc. Nat. Sciences); Canada (J. 

 Pettit). 



Three coincident specimens examined. In the dark fringes to the 

 hind wings C. residua resembles C. insolabilis-, but the species is 

 nearer C. obscura in its general tone, and especially in the dusky tint 

 of the fore wings, which differ by their acutely and strongly toothed 

 transverse posterior line.

? . In the appearance of the fore wings this species resembles C. 

 parta, but the basal dash and distinct apical streak are wanting, the 

 species is but little less than one-third smaller and the hind wings 

 are bright pinkish red as in the European nupta, which it more nearly 

 resembles. The fore wings are bluish grey, and differ from nupta, by 

 the greater equality of the extra discal teeth to the transverse poste- 

 rior line, and by the white subreniform, closed but connected with the 

 line, which is clouded in the European species, while their general 

 color is brighter, more bluish grey than in nupta. Hind wings, with a 

 nearly straight, nowhere excavate, black and even band. In nupta 

 this is elbowed, deeply excavated externally, opposite the cell. In 

 C. borealis the usual widening of the band at vein 5 is slighter than 

 usual. The band terminates abruptly before the margin and there is 

 no duskiness towards the base or along internal margin. Superiorly 

 the band is notably even, not diffusely widened as in Meskei, from 

 which it differs in the absence of the terminal attenuation" and crook- 

 ing. Marginal band as in nupta and allies with a broad and deep 

 ante-terminal sulcation. Beneath, the fore wings are like nupta, but 

 the bands are more even. Hind wings bright red inferiorly; the 

 median band wider than on upper surface. 



Expanse, 60 mm.
