 whitish. The abdomen pale reddish brown with a cupreous lustre, and the hind portions of the segments 

 tipped with white. Anterior wings dusky fawn-color, sometimes pale fawn-color, with a ferruginous brown 

 dot at the base, a square sub-median patch on the inner margin, a patch above the inner angle divided toward 

 its apex by the medio-posterior nervule and a large sub-apical patch, ferruginous brown ; from the sub- 

 median patch two faint brown lines are thrown off posteriorly to the costa, the most exterior being angulated 

 on the medio-central vein, and from its anterior portion are two other diverging brownish lines, with a faint 

 line above them near the base of the wing ; the disco-median shade is rather faint and brownish. The 

 posterior wings are pink, deepening in intensity toward the middle of inner margin, and above the interior
