expansion inwardly of the three lower spots, so as to 

 bring them under the cell. Below the median vein there 

 is a yellowish spot about one-third the distance from the 

 base to the margin. The anteapical spots and the two 

 beyond the cell are like those in M. Yuccce. Hind wings 

 with a yellow spot on the costa and a more distinct 

 yellow border, besides the discal row of yellow spots. 



The male has on the outer half of the fore wings an 

 irregular row of five pale yellow spots of various sizes 

 and shapes, the lower three pointed internally. The 

 hind wings have a rather narrow, even, straw-colored 

 border. Fringes dirty white. 



The under side of the fore wings of both sexes is like 

 the upper, the hind wings with the addition of some gray 

 shading on the costa and several subterminal white spots, 

 otherwise much as in the other species. 



The whole of the upper surface of the hind wings of 

 the male, except the space occupied by the outer border, 

 is thickly covered with long, fine, black hairs, which 

 stand nearly at right angles to the surface, to the height 

 of nearly a quarter of an inch. The basal third of the 

 under side of the fore wings is furnished with a similar 

 coat of hairy appendages.
