Head and thorax pale straw-colour^ the latter rather darker in front ; anterior 

 wings the same, appearing obscurely striated with rufescent, the nervures

 black spots, one placed at the bifurcation of the interior discoidal nervure, 

 the other between that and the hinder margin of the wing; the hinder margin 

 immaculate ; cilia reddish straw-colour : posterior wings white, slightly tinted 

 with cinereous towards the hinder margin, with an arcuated series of black or 

 fuscous spots, a little behind the middle, each spot being placed upon a ner- 

 vure; cilia white. 



I captured two specimens of this species at Ripley, in the be- 

 ginning of July, 1827.
