yellowish, orange in 9 \ cilia whitish-yellow, with a fuscous 

 median line. Hind wings pale-yellowish, in 9 orange or 

 orange-yellow ; markings of upper-side reproduced ; an obscure 

 fuscous streak above dorsum, becoming blackish and more 

 clearly developed on termen, where it becomes patch-like ; cilia 

 as in fore wings. 



This species is very distinct from all others by the absence 

 of any denned stigma; the raised scales on veins 1, 2, and 3 

 require close scrutiny to reveal them, and are apparently ab- 

 sent in some males, probably through denudation. Plotz's 

 figure is a good one, and represents the species clearly. The 

 species later on described as hypomeloma is somewhat like the 

 wing pattern, especially beneath, but the blackish streak along 

 the dorsum of hypomeloma is absent in dolon. Plotz's draw- 

 ing does not show the peculiar antennae of the genus, but I 

 attach no importance to this omission, as the drawing other- 

 wise agrees in detail. The additional spot on vein 7 of hind- 

 wings is rarely absent.

 Type Papyria, Bdv. 



This genus differs from Taractrocera only by the presence 

 of stigma in tf .

We formerly placed this and the following species in 

 Hubner's genus Apaustus, but as that genus, as now accepted, 

 is confined to South America I adopt Mabille's genus as 

 being in keeping with the characters of Bibla. The stigma 

 of o* is well defined. 



Larvse feed on Imperata arundinacea and the imagoes 

 frequent the blossoms of lucerne (Medicago sativa).
