and beyond to margin blackish -brown; the extra-discal points nearly or 

 quite lost on the dark ground; sub-marginal crescents black, obsolescent, 

 often wanting altogether; in the cell of primaries three elongated,' 

 narrow, deep black spots, two of which lie along the costal nervure, sep- 

 arated by a very small interval, and each edged by a velvety black line; 

 the third along median nervure, illy defined without such edging; the 

 spot on disk of secondaries dead white, bent at right angles; the lower 

 limb straight, thick abruptly sloping to a point by the cutting away of 

 its upper side; the upper branch narrower, slightly curved, nearly as 

 wide at top as elsewhere and ending bluntly; fringes with the white 

 area more extended than on upper side. 



Body above black, covered with ferruginous hairs, below black, 

 sometimes with a gray shade; legs gray-brown, palpi black at base and 

 in front, with whitish hairs at sides, ferruginous at top; antennae black 

 above, fulvous below; club black, fulvous at tip. 



Female expands from 2.1 to 2 3 inches. In shape very like the male; 

 upper side dull yellow-fulvous, the spots large; under side more brown 

 than black, the extra-discal area to margin pretty uniform in shade, the 

 ground being dark gray, nearly lost in the denseness of the brown 

 streaks; sub-marginal points and crescents obsolescent; silver mark of 

 same shape as in the male, often quite as heavy.
