This is the true Papilio centaurm t Fabr., of which I have satisfied myself by a comparison 

 with the Fabrician type contained in the Banksian collection in the British Museum. 

 Considerable confusion exists as to the true identity of this species, and this has been greatly 

 due and is still frequently caused by the erroneous representations of the species given by the 

 late Mr. Hewitson,* which seem to apply to a variety or distinct species found m Continenta] 

 India* It is probably these figures which have induced many to consider as distinct the Malay 

 butterfly described by Felder under the name of Ambiypodia nahih, Mr* Kir by > in his Catalogue, t 

 placed the two species as synonymous with one another; and, to render the matter as 

 complicated as possible, N. M. Kheil has recently pointed out that Mr, Kirby is wrong, and 

 uses Folder's name as distinct from the Fabrician. Mr. Butler, in 1869, J corrected this 

 rrnir, bul his remarks uppear Lo have been Overlook rd. 



This is an abundant Lycamid in the Malay Peninsula, and its distribution extends through 

 Tenasserim into Burma, but, owing to the confusion as to identity, its known geographical area 

 is somewhat difficult to ascertain*
