XXII.— Description of a new Papilio from Bali of the nox 
group. By Lione. DE Nicevixe, F.E.S., C.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 Zoologice,’ vol. 11. 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. erebus, 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. nyz, and Westwood says 
the female of P. erebus is “black above”’; while the latter 
eminent entomologist says also that his P. str¢x, 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. nyz#) as follows, adding that I have not seen 
specimens of P. noctis and P. noctula :— 
A. Upperside, both wings brown, 
a. Upperside, hind wing uniform brown. 
1. P. nox, 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.
