This belongs to a remarkable group of Papilios inhabiting the Austro-Malayan region, 
and which are especially interesting as exhibiting a good instance of polymorphism, the 
females being of two or three distinct forms. 
The male in this species is characterized by the small amount of marking on the under 
surface. 
1st form of female. Tab. ITI. fig. 1. : 
Almost exactly intermediate between the male and the normal female, which resem- 
bles P. Erectheus 2. 
` Upper side brown-black; a band of four whitish-yellow spots across the anterior 
wings beyond the cell, the upper one of the same size and position as in the male, the 
2nd and 3rd elongated towards the cell, the 4th rather shorter than the 3rd, and imme- 
diately beneath it. Posterior wings with a central patch of a pale sulphur-yellow just 
crossing the end of the cell, and separated below into five truncate lobes ; below this, and 
next the anal margin, are two irregular blue lunules, with a red lunule at the anal angle 
and a smaller one lower down beneath the second blue lunule. 
Under side as above; on the hind wings the upper half of the yellow patch is dusky, 
and there is a complete submarginal series of seven red lunules. 
Hab. Waigiou (a single specimen) (Wall.). 
2nd form of female. Tab. III. fig. 3. 
Resembles very closely P. Erectheus 9 ; but the white patch on the hind wings does 
not cover so much of the cell, and the two middle lobes are much elongated posteriorly, 
and separated by wedge-shaped spaces; the blue lunules are but slightly marked, and do 
not exceed two in number. 
Under side :—differs from P. Erectheus in the white patch never reaching the anterior 
margin of the hind wings. In a specimen from Waigiou, the four middle lunules are 
nearly white. This may be considered the typical form of female, as it occurs every- 
Where in company with the male. 
3rd form of female (Amanga, Bd.). Tab. III. fig. 4. | 
I have three specimens of this form from three of the localities in which the male 
occurs. They differ slightly from each other, but agree generally with the figure and 
description above quoted. An allied form of female (of the next species) was observed
