Pamphila guttata, Murr. P. Z. S. 1881, p. 912. 



Eudamus guttatus, Brem. & Grey, Schmett. nordl. China's p. 10 

 (1855). 



G-oniloba guttata, Men. Cat. Mus. Petr. i. t. v. fig. 4 (1855). 



Common all over Japan and Corea ; it can be easily distinguished 

 from P. pellucida by its longer, narrower wings, and by the spots 

 of the hind wing, which are almost in a straight line, while in 

 P. pellucida the arrangement is most irregular. 



141. Pamphila janronis. 



Pamphila jansonis, Butl. Cist, Ent. ii. p. 284. 



I took a single specimen at Gensan in June of what I consider 

 the male of the type in the National collection, which is a Japanese 

 specimen. 



It is very closely allied to P. pellucida, the only difference of 

 any importance being a conspicuous pale spot near the base of the 

 hind wing on the unders-ide. 1 have a large series of P. pellucida 

 and P. guttata, but can find no trace of this spot in any of them. 



142. Pamphila pellucida. 



P. pellucida, Murray, Ent. Mon. Mag. xi. p. 1/2 (1875). 

 This species is common all over Japan, Corea, and the Kurile 

 Islands during the warm months.

 p. II ; Men. Cat. Mus. Petr. i, t. v. fig. 8. 



Pamphila florin da, Butl. Cist. Ent. ii. p. 285 (1878). 



Occurs in Central Japan and Yesso, and is common at Fusan and 

 Gensan, Corea, in June and July ; a very variable species. 



144. Hesperia subhyalina. 



Pamphila subhyalina, ? , Brem. & Grey, Schmett. nordl. China's, 

 p. 10 ; Men. Cat. Mus. Petr. i. t. v. fig. 7. 



Allied to sylvanus, but easily distinguished by its larger size and 

 the semitransparent patches on the fore wings of both sexes. 

 Common in Corea ; occurs also in Yesso, and I believe in Central 

 Japan. 



145. Hesperia sylvatica. 



Pamphila sylvatica, Brem. Lep. Ost-Sib. p. 34, t. iii. fig. 10. 

 Pamphila leonina, Butl. Cist. Ent. ii. p. 286 (1878). 

 I took this species in Gensan in July, and Hakodate in August ; 

 it is recorded from Tokio.
