ill different species, while coustant in the same, great faciHties must he afforded for the 

 determination of specific identity and limitation. Yet, in practice, I fear this cannot he carried 

 out, without severing species which otherwise seem most closely allied, and linking others 

 which have little else in common." * 



Discarding the further generic segregation of Papilio for the reasons already given, and 

 uiial)le to separate Oniithoptem from that genus save in a suhgeneric sense, the writer can only 

 enumerate two genera as Malayan representatives of this suhfamily.

This genus is difficult to accurately diagnose in its neural characters, and these will be 

 more fully treated when discussing the different groups into which Papilio is divisible. As 

 already pointed out, the apparently four-branched median nervure of the anterior wings is 

 a strongly distinguishing character, and the free position of the third subcostal nervule of the 

 same wings sufficiently separates it from Leptocircus, the only other genus of Papilionince at 

 present known from the Malay Peninsula. The body is moderately large, the pronotum rather 

 stout and convex, the eyes prominent and rounded ; the palpi short, closely pressed to the 

 head, the apical joint being short and indistinct. 



PapiUo is widely distributed in most parts of the world, but the peculiarities of 

 geographical distribution will be best given in application to its different groups as found in 

 this fauna,
