Lepidoptera from Kiukiang. 115 



67. Papilio demetrius, Cram., Pap. Exot., iv., t. 385, 

 figs. E, F (1882). 



Var. carpentcri, Butl., Ann. Mag. Nat. Hist. (5), x., 

 p. 318. 



A single male specimen taken in June. 



68. Papilio alcinous, Klug, Neue Schmett., t. i. (1836). 



Papilio alcinous, var.. Gray, Cat. Lep. Ins., pi. iv., 

 figs. 2, 3. 



P. mencius, Feld., Wien. Ent. Mon., vi., p. 22 (1862). 



P. spathatus, Butl., Ann. & Mag. Nat. Hist. (5), vii., 

 p. 139. 



P. plutonius, Oberth., Et. Ent., ii., p. 16, t. iii., fig. 2 

 (1876). 



After comparing hundreds of specimens from China 

 and Japan, I am unable to find sufficient differences to 

 separate the above forms. M. Oberthur, Et. Ent., ii., 

 p. 16, mentions the shape and length of tails, shape of 

 hind wings, and red spots as characters by which the 

 forms may be distinguished. In an extensive series of 

 specimens, however, such as that before me, it is seen 

 that all these characters are subject to considerable 

 modification, so that it is not possible to place reliance 

 upon them. 



69. Papilio sarpedon, L., var. (PI. VII., fig. 2). 



The variety figured is the common form of P. sarpedon 

 at Kiukiang, and differs from the type in being without 

 the band-like series of blue spots on secondaries. Other 

 examples are intermediate,* and connect the variety 

 with the type. Ningpo and Ichang specimens exhibit 

 no tendency whatever to vary in the direction of this 

 form. 



70. Papilio xuthus, Linn. 



Var. xuthulus, Brem., Lep. Ost.-Sib., p. 4, t. i., fig. 2. 



Both forms, as well as intermediates, occur commonly. 



* One of these has been named var. semifasciatus by Herr 

 Honrath. Eutom. Nachr., xiv., p. ICl (June, 1888).
