XXII. — Description of a new Papilio /rom Bali of the nox 

 group. By LIONEL DE NiCKVILLE, F.E.S., O.M.Z.S., &C. 



The butterfly described below comes into Section B of the 

 nox group of Papilios as defined by the Hon. Walter Roth- 

 schild in ' Novitates Zoologica3,' vol. ii. p. 258 (1895), 

 which is characterized by the margin of the abdominal fold 

 of the hind wing in the male, when fully expanded, having 

 a fringe of long hairs * ; the basal partition of the subcostal 

 nervure of the same wing in both sexes is short ; and the 

 abdomen in both sexes black, or red only at the apex. All 

 the females of this section (except the species described 

 below, which was unknown to Mr. Rothschild) are said by 

 that writer to have the upperside of the fore wing " brown " ; 

 but P. erebuSj Wallace, which I have from Sumatra only (it 

 occurs also in the Malay Peninsula and in Borneo), cer- 

 tainly is dark blue-black as in P. ni/x, and West wood says 

 the female of P. erehus is " black above " ; while the latter 

 eminent entomologist says also that his P. strix^ which is the 

 female of his P. noctula, is " black " above. I would recon- 

 struct Mr. Rothschild's key to the females of the group 

 (including P. nyx) as follows, adding that 1 have not seea 

 specimens of P. noctis and P. noctula : — 



A. Upperside, both wings brown. 



a. Upperside, hind wing uniform brown. 



1. P. 7Jo.r, Swainson : Java. 



b. Upperside, hind wing with a band of dirty white near the outer 



margin. 



2. P. noctis, Hewitson : Borneo. 



• Mr. Rothschild says his Section A also has a fringe of long hairs. 

 This, however, is a clerical error ; all the species in the Section lack 

 these hairs.
