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. 



Istform of female. Tab. III. fig. 1. 



Almost exactly intermediate between the male and tlie normal female, whicb resem- 

 bles P. Erectheus ? . 



Upper side brown-black; a band of four whitisli-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 -ith 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 lumile 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. AVaigiou (a single specimen) [Wall). 



2tidform of female. Tab. III. fig. 3. 



Eesembles very closely P. Erectheits ? ; 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 F. Erectheus in the white patch never reaching the anterior 

 margin of the hind wings. In a specimen from Waigiou, the four middle luniiles are 

 nearly white. This may be considered the typical form of female, as it occurs every- 

 where in company with the male. 



Zrdform of female {Amanga, Bd.). Tab. III. fig. 4. 



I have three specimens of tliis form from three of the locahties 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
