smoky with a yellowish tiuge in the female, veins and a discal lunule 

 darker. In the male there is an evident exterior dusky line, more or 

 let^s broken, beyond which the wing is somewhat smoky to the smoky 

 terminal line. Fringes white in both sexes and in the male unusually 

 long. Beneath whitish gray, rather even^ with a distinct discal spot 

 and a broad, blackish outer line nearly complete on all wings. 



Expanse, 30 to 33 mm.= 1.20 to 1.32 inches. 



Habitat. — Oregon (Schaus). 



Two males and one female, all different. The female is best marked 

 and the main points in the description are from that specimen. One of 

 the males is similar but much more obscure, all the black being changed 

 to smoky brown, and in neither of these is the median shade anything 

 more than a vague suggestion. The second male is intermediate in dis- 

 tinctness of maculatiou save that the shadings to the subterminal line 

 are obscured by a universal dusky shading, and here the median shade 

 is present without doubt and darkens the space between the ordinary 

 spots. These latter are large also in this last specimen, and I was at 

 first strongly inclined to reject it as a member of this species. It agrees, 

 however, in all other features, and particularly in the outer line of the 

 secondaries above, which is not usual, and in the broad outer line of 

 the under side. 



The antennal processes in the male are unusually long, so that the 

 brush-like structure is j)rominent. 



35. CARNEADES DAKOTA, new species. 



Ground color a sordid clay yellow, powdered with smoky. Head and 

 thorax concolorous. Vestiture hairy, but coarse and somewhat fat- 

 tened; the tuftings not obvious in the specimens. Primaries without 

 contrasts, the ordinary maculation written in blackish. Basal line 

 unusually distinct, geminate, the two portions well separated. Trans- 

 verse anterior line upright or a little oblique outwardly, marked by gemi- 

 nate black spots on the costa, below which the inner line is lost, and 

 the outer is made up of three interspaceal lunules preceded by a some- 

 what paler shade. Transverse posterior line geminate on the costa, the 

 outer line becoming lost in the outcurve over cell, inner line slender, 

 crenulate, very oblique inwardly below the cell and a little incurved. 

 Subterminal line vaguely marked by a slightly darker subterminal 

 shade. A series of smoky, interspaceal terminal lunules. Median 

 shade broad, diffuse, smoky, almost upright, and crossing just inside the 

 reniform. Claviform absent. Orbicular absent or marked by a dusky 

 central dot. Reniform marked by a blackish or smoky kidney-shaped 

 spot. Secondaries dirty-gray at base, smoky fuscous outwardly, fringes 

 nearly white. Beneath whitish, powdery, both wings with outer lines 

 and discal lunules. 



Expanse, 32 to 34 mm.= 1.28 to 1.3(> inches. 



Habitat. — Dakota: No definite locality.
