The type of this species is still preserved in the Stockholm Museum, and agrees 

 best, according to Aurivillius (Lc), with Hiibner's figures of.Tavan specimens. The 

 Papil/o sarijedon of the whole of the Indo-ilalayan subregion, including the 

 Philippine Islands and Japan, and excluding Ceylon and South India, can scarcely 

 be split up into local forms. The P. sarpedon of China, however, are mostly different ; 

 unfortunately these differences are not at all constant. The Japanese spring brood 

 is mostly the same as typical P. sarpedon; the specimens of the summer broods ai-e 

 larger, the green band of the wings is narrow and mostly interrupted at the veins, 

 and the hindwings are produced into a tooth at the end of the upper median nervule 

 (not quite so much as in P. sarpedon teredon Feld. from South India and Ceylon), 

 and agree very well with such Chinese examples which have a complete median band 

 to the wing that is interrupted on the forewings at the nervules. I think it not 

 advisable to treat the Japanese sarpedon as a separate subspecies, as the distinguishing 

 characters are found only in a relatively small number of individuals. 



I divide the present species into the following geographical races : — 



(ft) : P. sarpedon L. from Continental India to Java, tiie Philippines, and Japan, 

 exclusive of South India and Ceylon ; 



(b) : P. sarpedon semifasoiatus Hour, from China ; 



(c) : P. sarpiedon teredon Feld. from Ceylon and S. India ; 



(d) : P. sarpedon parsedon Westw. fi'om the lesser Sunda Islands ; 



(c ) : P. sarpedon choredon Feld. from Australia, New Guinea, Waigeu ; 



(/) : P. sarpedon imjMrilis m. from the Bismarck Archipelago ; 



((/) : P. sarpedon imp/ar m. from the Solomon Islands ; 



(h): P. sarpedon anthedon P'eld. from the .Moluccas ; 



(i): P. sarjjedon milon Feld. from Celebes, Sulla Islands, Talaut Island. 



(a): P. sarpedon L., forma typ. (cf, ? metam.). 



The red sjjots on the underside of the hindwings assume sometimes an orange 

 yellow tint. 



JI. de Nic^ville figures (J.c.) a curious melanistic aberration of this species 

 which has almost entirely lost the green band of the wings. I have a Darjeeling 

 specimen which shows the beginning of melanism, the median band being thinly 

 overpowdered with black scales, and part of the scales of the upper layer of the 

 band beneath having become black. It is not the green colour of the band which is 

 replaced by blacl* In P. antiphaies ab. nebulosus Butl. and in P. aristeus ab 

 nigricans Eimer the white scales have assumed a black colour ; on the upperside 

 of the wings of the melanistic sarpedon the scaleless band becomes scaled black. 

 A specimen of P. eiirypylus axion Feld. in the Hewitson Coll. (Hrit. Mus.) has the 

 markings also partly black, and exhibits the same additional scaling as the melanistic 

 Bnrjjeilon. 



Hah. Continental India (exc. South India) (25 J); Malacca (7 J); Sumatra 

 (6 c?) ; Nias ; Kngano (1 (?) ; Java (2 cJ, 1 ? ) ; Bunguran,;Xatuna Ishmds (2 cj, 2 ? ) ; 

 Borneo (ISc?); Palawan (3 (?) ; Philippines (7 <?) ; Loo Choo Islands (It?, 1?); 

 South Japan (18 (?, 3 ?), 



In Cliiiia tliere occur specimens, together with typical P. sarpedon and examples 

 which are like those of the Japanese summer brood, rather abundantly in which the 

 median band of the hindwings is more or less obliterated ; in the form of the hind- 

 wings these specimens agree mostly with the Japanese summer bnwd. Here we 

 have a case that in one locality part of the specimens are quite dift'ert-nt from the
