886 MR. H. J. ELWES ON THE BUTTERFIJES [NoV. 15, 



? Thecla w-ALBUM, Knoch, Beitrage, ii. p. 85 (1781). 



Found at Pekia {Bremer) ; a specimen from there is in the British 

 Museum. Also at Shanghai (Pryer). 



Differs from the European msect in having usually a larger blue 

 spot at the anal apex, and a double line of pale lunular markings on 

 the fore part of the hind wing below. No specimen in Dr. Stau- 

 dinger's collection quite agrees with this, which may be a distinct 

 species. 



T. mera, Jans. Cist. Ent. ii. p. 157 (1877). 



This species, found at Matzabaro, Japan, by Mr. Jonas, is allied 

 to T. pruni of Europe ; but the few specimens I have seen differ 

 sufficiently from that species. 



T. shjgiana, Butl. Ann. & Mag. Nat. Hist. 1881, vii. p. 35, t. iv., 

 fig. 6, from Nikko, seems very near it ; but the type specimen is not 

 fresh enough to be described with accuracy. 



T. PRUNOiDEs, Stdgr. MSS. 



This was taken at Vladivostock by Christoph ; but though very 

 near T. w-album, the markings of the hind wing beneath are, as Dr. 

 Staudinger thinks, sufficiently different to separate it from that 

 species. He has also a specimen from the Altai. 



T. PRUNI, Linn. Syst. Nat. x. p. 482. 



Occurs at Vladivostock and on the Lower Ussuri. 



T. PHYLLODENDRi, Stdgr. MSS. 



A distinct species allied to T. pruni, but distinguished by a double 

 line of black spots on the underside of both wings. It was taken at 

 Vladivostock by Christoph, and at Baranofsky by Dbrries. 



?T. spiNi, Schiff. S. V.p. 186. 



Recorded by Bremer from Pekin, and by De I'Orza from Japan ; 

 but I have seen no specimens from Asia, and Dr. Staudinger has 

 none from any locality east of the Caspian. 



T. RUBi, Linn. Syst. Nat. x. p. 483. 



Recorded by Bremer from Onon (Eadde), and by De I'Orza 

 from Japan; but I have seen no specimens from Eastern Asia. 



T. ENTHEA, Jans. Cist. Ent. ii, p. 157 (1877). 



A very distinct species, easily known by the coloration and spots 

 of the under surface. 



It was described from the Yokawa river, Japan, collected by Jonas, 

 but is rare in collections. I have seen a specimen in Dr. Stau- 

 dinger's collection from Vladivostock (Christoph) which agrees 

 perfectly with it.
