14 Mr. A. G. Butler on Japanese 



Corea ; those forms which have their representatives in Japan 

 are more worn and rubbed than the typical Japanese species 

 occurring with them, thus indicating that their time of emer- 

 gence from the pupa is earlier. The fresher species are chiefly 

 females, the males having not yet emerged when Mr. Perry 

 left the country. 



For my part, knowing that Lepidoptera said to come from 

 the Amur fetch a higher price than their allies from Japan, I 

 should at all times receive with the greatest caution any state- 

 ment of the identity of specimens the history of which was not 

 beyond all question. 



The following is a list of the species : — 



Nymphalidse. 



Sattbin^. 



1. Satyrus dry as. 

 Papilio dryas, Scopoli, Eut. Cam. p. 153, fig. 429 (1763). 

 Posiette Bay, Corea, N.E., August 1881. 



2. Satyrus hipunctatus. 



Satyrus bipunctatus, Motschulsky, Etudes Entom. ix. p. 29 (1860). 



Hakodate and Kobd, in July ; Yokohama and Posiette Bay, 

 Corea, in August. 



3. Satyrus liyperantus. 



Papilio liyperantus, Linnaeus, Fauna Suecica, p. 273 (1761). 

 Posiette Bay, Corea, KE., August 1881. 

 4. Satyrus ocellatus, sp. n. 



2 . Nearly allied to S. liyperantus^ but with all the ocelli of 

 about three times the size ; those on the under surface with 

 confluent irides and oval in form. Expanse of wings 

 2 inches. 



Posiette Bay, Corea. 



Although the ocelli in ;S'. liyperantus are very variable, this 

 variation is in a decreasing direction from the normal condi- 

 tion ; I have never seen them enlarged so as to give the 

 insect the aspect of a Mycalesis or Yptliima ; and therefore I 

 have thought it best to give this form a name. 



5. Neo])e Fentoni. 



Neope Fento7ii, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xix. pi. xci. 

 (1877). 



c? ? . Posiette Bay, Corea.
