1887.] OF JAPAN AND COREA. 413 



is fawn-coloured with tlie characteristic bars and markings of a 

 darker shade ; whilst the underside of T. arata is mouse-coloured 

 with ashy-white markings. The type iu the National collection is 

 from Kiukiang. 



42. Thecla attilia. 



T. attilia, Brem. Lep. Ost-Sib. p. 24, t. ii. fig. 3. 

 Occurs in Northern and Central Japan. Mr. H. Pryer says it is 

 common in the neighbourhood of Yokohama. 



4!3. Thecla ibara. 



Tkeclaihara, Butl. P. Z. S. 1881, p. 852 ; Aid to Tdeutif. of Ins. 

 pi. 113. 



This species, which must be extremely rare, differs from the other 

 Japanese Theclce in having a greenish underside with a white 

 submarginal band and a yellowish blotch, containing two black dots 

 at the anal angle of the hind wing. 



I believe the only specimen of this species is the type in Mr. 

 Fenton's collection, which was taken in the second week of July on 

 the Ibara pass, Dewa. 



44. Thecla orsedice. 



T. orsedice, Butl. P. Z. S. 1881, p. 852. 



Of this distinct species I only took a single specimen at Tsuruga, 

 on the west coast of Central Japan. The type is recorded from 

 Iwashiro in Yesso. 



45. Thecla fentoni. 



Strymon fentoni, Butl. P. Z. S. 1881, p. 854 ; Aid. to Identif. Ins. 

 pi. 115. 



Closely allied to w-alLum, but blacker, the tails longer, the line 

 on the underside of fore wing straighter, and the yellowish blotch 

 at the anal angle of the underside of the hind wing quite different. 

 There is an unnamed specimen from Pekin in the National collection 

 which is, I believe, this species. The type, which is in Mr. Fenton's 

 collection, is from Shiribetsu in Yesso. I took a single specimen at 

 Gensan at the end of June. 



46. Thecla mera. 



T. mera, Janson, Cist. Ent. ii. p. 15/ (1877). 

 This seems a scarce species, and is I believe only recorded from 

 Nikko. 



47. Thecla stygiana. 



T. stygiana, Butl. Ann. & Mag. Nat. Hist. ser. 5, vii. p. 3o, t. iv. 

 fig. 6 (1881). 



Allied to the last species, but distinct ; it is also recorded from 

 Nikko.
