 indistinct blackish points. 



Secondaries have three spots next base and a discal spot, all obscure; 

 a median tortuous row of large blackish spots, edged without by white, 

 and a marginal row partly lunulate, the first from angle nearly obso- 

 lete, surmounting a grey space, the second largest edged posteriorly by 

 a few fulvous scales and above a round black spot; the fourth and fifth 

 points. 



Female. Expands 1.15 inch. Similar to male, less deeply colored ; 

 on under side spots generally larger ; the three next anal angle marked 

 by fulvous scales.
