RIIOPALOCERA MALAYAN A. 



in lifferent species, while constant in the same, great facilities must be afforded for the 

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

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

 which have little else in common.* ' 1 



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

 unable to separate OmithopUra from that genus save in a subgeneric sense, the writer can only 

 enumerate two genera as Malayan representatives of this subfamily.

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 PapUio is divisible. As 

 already pointed out, the apparently four -branched median nervnre 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 Leptocireits t the only other genus of Papiliomn& at 

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

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

 head, the apical joint being short and indistinct. 



Papilio 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. 



:: Messrs. Sftlvin and Godinan have for the last few years exliaustively studied those organs in the Neotropical 

 lihopalocera, and made magnificent preparations of the same. The early publication of these details is greatly to be 

 desiderated.
