 wing (figs. 64-67) ; fringe white except for fuscous suffusion at apex 

 and tornus; underside of forewing lightly shaded with fuscous, pattern 

 of dorsal surface clearly visible from beneath. Secondaries thinly

 pale fuscous, becoming whitish toward wing base.

 intermixed ; entirely white below. 



Male genitalia (fig. 94). — Apex of tegumen bilobed. Outer

Female genitalia (figs. 120, 139).— Apex of ovipositor with dorsal 

 ridge present, gradually terminating into ovipositor shaft; ridge with 

 approximately 20-25 teeth. Signum stellate, well developed, number 

 of rays usually 13-16.
