1887.] OF JAPAN AND COREA. 409 



In one spot near Nagahama (Lake Biwa) I found the forms 

 described as poUographus, sirnoda, subaurata, and elwesii all together ; 

 and of six pairs which I took in copula and kept separately labelled, 

 only two pairs were of the same form, viz., sirnoda ; the remainder 

 were as follows : — 



2 cases of sirnoda c? and elwesii 5 . 

 1 case of suhcmrata c? and elwesii $ . 

 1 case of simoda S and poliographus 2 . 

 The infei'ence is that they belong to the same species ; otherwise 

 they hybridize in a manner totally unprecedented and highly im- 

 probable. 



The type of pa/lens is such a bad specimen, that it is impossible 

 to say what it is. 



24. Terias l^ta. 



T. Iceta, Boisd. Sp. Gen. i. p. 674. 



Yarjaegeri, Men. Cat. Mas. Petr. p. 84, t. ii. fig. 1 (1855). 



T. subfervens, Butl. 



A common species in spring and autumn all over Southern and 

 Central Japan. A series in the National collection labelled suhfervens, 

 Butl., do not differ materially from Japanese specimens, and some of 

 the Northern Indian forms are not separable. 



Mr. H. Pryer says that it occurs all through the summer. 



25. Terias bethesba. 



T. bethesba, Janson, Cist. Ent. ii. p. 272 (18/8). 

 This species, which is very distinct from the other Japanese Terias, 

 occurs in Central and Southern Japan in May and again in August. 



26. Terias hecabe, Linn. 



T. hecabeoides. Men. Cat, Mus. Petr. i. p. 85, t. ii. fig. 2. 



T. sinensis, Luc. Rev. Zool. 1852, p. 429. 



T. mariesi, Butl. Trans. Ent. Soc. 1880, p. 198, t. vi. figs. 1-7. 



T. anemone, Feld. Wien. ent. Mon. vi. p. 23 (1862). 



T. mandarina, de I'Orza, Lep. Jap. p. 18 (1869). 



T. hobsoni, Butl. P. Z. S. 1880, p. 668. 



T. hybrida, Butl. Trans. Ent. Soc. p. 199. 



T. connexiva, Butl. Trans. Ent. Soc. p. 199. 



Common all over Southern and Central Japan, and recorded from 

 S.E. Corea. It is needless to say anything about this well-discussed 

 question, as Mr. H. Pryer has settled it in the most conclusive 

 manner by breeding all the forms known from Japan, from eggs 

 laid by the same parent. 



27. Miletus hamada. 



Miletus hamada, Uruce, Cist. Ent. i. p. 361 (18/5). 



I found this species common ail up the west coast of Central 

 Japan ; it also occurs at Nikko. It seems fond of water, and flew 

 about amongst the thick bamboo-grass on the banks of streams in 

 July and August.
