1881.] OF AMURLAND, NORTH CHINA, AND JAPAN. 873 



Papilio pammon, Linn. Mus. Ulr. p. 189 (1764). 



P. jmmmon, var. borealis, Feld. Wien. ent. Mon. vi. p. 22 (1862). 



Japan {De I'Orza), Yokohama {Pryer) ; Shanghai (Prtjer), 

 Ningpo {Felder). 



I cannot follow in Shanghai specimens the characters by which 

 Felder separates the variety borealis ; the female, however, differs 

 from any I have seen in the absence of the white spots on the hind 

 wing above, which are replaced by pinkish. 



P. HELENus, Linn. Mus. Uh-. p. IS.'j (1764). 



P. nicconicolens, Butler, Ann. & Mag. Nat. Hist. ser. 5, vii. p. 139. 



The Japanese insect, which seems rare, differs, according to 

 Butler, in the form of the spots on the hind wing. I have, however, 

 compared the type of P. nicconicolens (a name which should be re- 

 jected, as barbarous) with Lidian and Chinese specimens, and think 

 that it can at most be considered as a variety of helenus, some spe- 

 cimens of which from Hongkong and Darjeeling are A'ery near it. 



P. MEMNON, Linn. Mus. Ulr. p. 193 (1764). 



P. thunbergii, Siebold, Hist. Nat. Jap. p. 16 (1824). 



P. thunhenjii, Sieb., Butler, Ann. & Mag. Nat. Hist. ser. 5, vii. 

 p. 133. 



If this species presented a constant variation in Japan, there 

 might have been some reason for separating it; but the few 

 specimens I have seen from Japan are not all alike, and vary as 

 they do elsewhere. The females seem to be tailless in Japan. I 

 have not seen it from Central or North China. 



P. SARPEDON, Linn. Mus. Uh'. p. 202. 



P. teredon, Feld. Reise Nov. Lep. i. p. CI (1865). 



Not rare in Central Japan. 



The form described by Felder as P. teredon is from Ceylon ; and 

 I cannot see why the Japanese insect, which appears identical with 

 Himalayan specimens, should be referred to it, as has been done by 

 Mr. Butler in his list of the Butterflies of Nikko (Ann. & Ma*. 

 Nat. Hist. ser. 5, vii. p. 133). ° 



P. AGAMEMNON, Liuu. Mus. Ulr. p. 202. 



Recorded by De I'Orza from Japan ; but I have seen no specimens 

 from there, though it occurs in Fryer's collection from Shanghai. 



P. ERiTHONius, Cram. Pap. Ex. iii. t. 232 (1782). 

 I have only seen specimens from Foochow {Pryer). 



P. ALEBioN, Gray, Cat. Lep. B. M. i. p. 30, t. xii. fig. 6. 



North China, ? Shanghai {Fortune) ; Kiukiang (Maries). 



The Chinese representative of P. glycirion. 



P. tamerlanvs, Oberthiir, Ef. Ent. ii. p. 13, t. ii. fig. 1 (1876), 

 from Moupin, which I have seen in Dr. Staudinger's collection] 

 seems the same as P. alebio?K
