grey border. Beneath : the costa and apex of the uppers darker, 

 the posterior band of the hind wings much broader, and the 

 nervures more widely margined, the submarginal spots very 

 small.

Second variety. — Above, whiter, nearly like P. eperia, the apex 

 dark, with small white linear spots, and a single dark band to the 

 end of the discoidal cell. Beneath, paler, the submarginal band of 

 the hind wings abruptly angular as in P. eperia, and the submar- 

 ginal spots more elongate and nearly white. Female : above, 

 blackish, with white patches between the nervures chiefly in and 

 near the cell ; beneath, like the male, but the nervures more broadly 

 dark-margined. 



i/fl6.— Macassar (Coll. Wall.). 



The last variety closely resembles P. eperia beneath, but the 

 form of the wings is quite different. This seems to be a variable 

 species, and a greater number of specimens would probably pre- 

 sent intermediate forms. The Sula Islands are zoologically a part 

 of Celebes, as is well shown by their birds.

Hab. — Macassar, Menado (Wall.). 



This fine species differs much in form from all its allies, having 

 the abrupt band of the costa and the elongated wings characteristic 

 of many Celebes butterflies. The specimens from Menado are 

 more richly coloured beneath.

 Hab. — Borneo (ho< Bogota), (Brit. Mus. Coll.). 



This is near P. coronis and P. ejjeria, but is quite distinct. By 

 an oversight the habitat is given as '' Bogota," whicii may easily 

 lead to its being overlooked by persons studying Eastern Lepi- 

 doptera.
