 which is angulated and a little bent down ; hind margin 

 perpendicular or even filled out, a little rounded off below the 

 middle ; dorsal margin straight to near the base, where it is 

 rather arched ; colour most frequently silvery greenish-grey ; 

 basal line angulated and abbreviated but very faint, purplish- 

 brown ; a little beyond it is a still fainter, almost parallel, 

 similar line ; usual first line near the middle of the wing, 

 perpendicular, double, repeatedly angulated, purple-brown ; 

 second line but a short distance beyond, waved and bent in
