﻿ix. d, 3 Wileman: Notes on Japanese Lepidoptera 257 



Dyar 1S remarks that — 



the larva of Papilio alcinous Klug is allied to the American philenor, and 

 retains in the last stage the peculiar black and white coloration, resembling 

 bird excrement, so characteristic of most all young Papilios. 



Seitz and Jordan 19 give many forms of the P. alcinous group 

 which is distributed from Japan to western China and Tonkin. 

 Seitz remarks that "P. alcinous Klug is a black, geographically 

 variable, Papilio which inhabits the Pacific district of the 

 Palaearctic region" and that "it is almost exclusively Palaearctic, 

 only a few forms entering the most northern districts of the 

 Oriental Region." The forms given by them are quoted for 

 convenience of reference, although only three of them inhabit 

 Japan proper; the rest are mostly Chinese. 



Papilio alcinous Klug (Seitz, 1, 9, PI. 2a, 2b) (= spathatus Butl., hxma- 



tostictus Butl.), from Japan. 

 Papilio nagasakii Fruhst. (Seitz, 1, PI. 2a, c? $; PI. 2b, c? S, f. aest), from 



southern Hokkaido (Yezo), Honshu, and Kyushu. 

 Papilio confusus Rothsch. (Seitz, 1, PI. 2c, S ?), from China, southward to 



Yunnan. 

 Papilio plutonius Oberth. (Seitz, 1, PI. 2c, <$ ?), from central China and 



Tibet. 

 Papilio dsemonius Alpher. (=: fatuus Rothsch.), from Ta-tsien-lu, western 



China and Tibet. 

 Papilio impediens Rothsch. (Seitz, 1, PI. 3a), from Ta-tsien-lu, western 



China. 

 Papilio mencius Feld. (Seitz, 1, PL 2b, c? ?), from central and southeastern 



China. 

 Papilio bradanus Fruhst. (= intermedia Oberth.) (Seitz, 9, 33), from the 



Sannan group (Ishigaki-Shima, Loochoo Islands) . 

 Papilio decora Oberth. ab. (Seitz, 9, 33), locality not given. 

 Papilio loochooanus Rothsch. (Seitz, 9, PL 19c, 3; r. 1, PL lc, $, underside), 



from the Loochoo Islands (Ryukyu). 

 Papilio mansonensis Fruhst. (= mausonensis Fruhst.) (Seitz, 9, 33) ; from 



Formosa, eastern and central China (westward to Chang-yang), and 



Tonkin; the male is not distinguishable from the species from western 



China, P. confusus, but the female is as pale as in P. loochooanus. 



According to Matsumura, P. alcinous occurs in Honshu, Shi- 

 koku, Kyushu, and the Loochoo Islands (Ryukyu) ; also, in Korea 

 and China. It flies from March to September in two broods, 

 spring and summer, both of which are figured by Seitz. 



The following description of a Papilio larva was entered in 

 my notebook on May 2, 1908. The larva was taken by me at 

 Kanshirei, in southern Formosa, but unfortunately never pupated,
