There is nothing whatever in the Asiatic form (i. e. planus. 

 Walk.) of S. ocellatus to separate it from that species. As we find 

 variation in colour and markings in any good series of European 

 S. ocellatus, so also do we find this to be the case where a number of 

 Japanese specimens of the species are brought together. These 

 last are exactly like Kiukiang and Gensan examples, and there is 

 not a specimen in my Asiatic series for which I cannot find an exact 

 counterpart among my European series. Pryer says of (S. planus, 

 "The larva is green with a green horn instead of sky-blue as in 

 iS. ocellatus.'^ As no other point of difference is referred to, it is to 

 be assumed that none existed, and I cannot think that any value can 

 possibly attach to such an unimportant character.

 Clanis deucalion, Butl. /. c. fig. 5. 



This is Pryer's no. 19, of which he observes in his catalogue 

 " common about Yokohama," but of which it appears he did not 

 keep a long series, as there were only three examples in his collection. 

 One of these specimens ( c? ) agrees well with examples of C. bilineata 

 from Kiukiang, whilst the other two ( $ $ ) are the deucalion of 

 Butler. I cannot find any trustworthy character by which the last- 

 named form can be specifically separated from G. bilineata.
