Wings rufous brown, often more obscure at the base, with n 

 black border extending from the upper edge of the primaries to 

 the anal angle of the secondaries. 



The primaries have on both sides a number of white spots on 

 the upper edge and disk, forming usually two marginal ranges, of 

 which the outer divides the border. 



The secondaries have sometimes the black border without any 

 points, and sometimes it is divided by one or even two ranges of 

 white points. 



The under side of the primaries differs very little from the 

 upper; but the under side of the inferiors is divided by wide 

 black veins, bordered with whitish. The disk has three or four 

 white points, situated on the edge of the discoidal cellule. The 

 black marginal border is divided by two rows of white points. 



The nervures on the upper surface of the secondaries in the 

 female are finely lined with grayish white. 



The larva, which feeds on Nerium, Asdepias, &c., is whitish 

 violet, with transverse stripes of a deeper color; a transverse band 

 of reddish brown, on each ring, divided in its length by a narrow 

 yellow band. Along the feet a longitudinal band of yellow citron. 

 Ijong, fleshy processes, of brown purple, disposed in pairs on the 

 second, fifth, and eleventh rings.
