stouter and lateral margins more convex; sacculus without a somewhat 
extenuate, truncate production from dorsal margin. 
Frmats (fig. 167).—Alar expanse 22 mm. Similar to male in color 
and maculation but with markings stronger. Genitalia (fig. 99) 
similar to those of bifidalis but collarlike structure narrower, with
