I was disposed to consider the Japanese and Amur form of this 

 species distinct till I saw the series of T.frioaldszkyi in Dr. Staudinger's 

 collection. He, however, judging from a typical Japanese specimen 

 I showed him, tliinks them identical. As a rule the Japanese in- 

 sect is deeper in colour on the underside ; but a specimen in Hewit- 

 son's collection from Yesso, where I believe the type of T.ferrea was 

 taken, is nearer to the Amur form. 



Mr. Murray considers this species to form a distinct genus ; and 

 it is certainly very unlike any other European or Asiatic Thecla, 

 though apparently very nearly allied to Thecla irus, God., and other 

 North- American species.

Found at Pekin (Bremer) and in the Apfelgebirge by Radde, also 

 on the Upper Amur by Hedemaun.

Found in Amurland, Japan, and China. 



Dr. Staudinger says the Amur variety resembles the American 

 one, having the red line on underside of hind wings more conspicuous 

 than in European specimens. 



I see nothing remarkable in the Chinese insect, of which I have 

 three from Ningpo ; one of these is much larger than European 

 specimens. All the Japanese and one of the Chinese specimens are 

 of the dark summer brood {eleus, Fab.).

This species seems to be widely distributed through Northern and 

 Eastern Asia, China, and Japan. I have compared many specimens 

 from Amurland, Shanghai, and Japan, and find them so very variable, 

 both in size, colour, and the spots of the hind wing, that I am unable
