is replaced by bister (PL 8, fig. 278). There are further examples in which the 

 medial area of each wing is suffused with fuscous black comparable with tulbaghata

 fuscous black (PL 8, fig. 280). The genitalia afford the most certain means of

 broad, shallow ostium bursae together with the form and proportions of the mem- 

 branous and sclerotized parts of the bursa copulatrix are diagnostic.
