1881.] OF AMURLAND, NORTH CHINA, AND JAPAN. 893 



Athyma pryeri, Moore, Ann. &Mag. Nat. Hist. ser. 4, xx. p. 47. 

 From the Snowy Valley, near Ningpo {Pryer). 

 This species seems very near the last, but has the second white 

 baud on the hind wings reduced to a line of spots margined with white. 



LiMENiTis helmanni, Lcdcrer, Verh. zool.-bot. Gesellsch.Wien, 

 1853, p. .356, t. i. fig. 4. 



Found at Askold, Blagovetschensk, Onon, the Ussuri, and also, 

 according to De I'Orza, in Japan, though I have seen no specimens 

 from there. Specimens from the Altai have the bands and spots 

 narrower than Amur specimens. 



? L. HOMEYERi, Taucre, Eni. Nach. 1881, p. 120. 



Seems to me but a variety of L. helmanni, though some specimens 

 have a distinct marginal white line on upper surface of hind wings, 

 which is faint or absent in L. helmanni. 



Found at Eaddefskaia, Blagovetschensk, and the Ussuri. 



L. amphyssa, Men. Schrenk's Reise, p. 21, t. iii. fig. I. 

 Found in many parts of the Amur region, and, according to De 

 rOrza, in Japan ; but I have never seen specimens from the latter. 



L. sYDYi, Led. Verh. zool.-bot. Gesell. Wien, 1853, p. 357, t. i. 

 fig- 3. 



Var. hitifasciata, Men. Schrenk's Reise, p. 30, t. iii. fig. 1. 



De rOrza says that Japanese specimens (which, however, I have 

 never seen) hardly differ I'rom Altai specimens. This is probably an 

 error, as L. sydyi has not been found on the Amur, and the variety 

 L. latifafciata is very distinct in all the sjiecimens I have seen, having 

 the white bands on both wings nearly twice as broad as in typical 

 L. sydyi. Indeed, if no intermediate forms occur, I think it might 

 fairly be separated. 



L. POPULi, Linn. Syst. Nat. x. p. 470". 



Found at Raddefskaia, on the Ussuri, and in the Bureija Mountains. 



The males from Amurland have the white bands as broad as in 

 females from Europe, and differ remarkably from European males, 

 which are, in some locahties at least, usually of the form known as 

 L. tremulce, Esp. 114. 



L. NYCTEis, Men. Schrenk's Reise, p. 28, t. ii. fig. 11. 



Alhyma cassiope, Men. loc. cit. p. 27, t. ii. fig. 10. 



Found at Raddefskaia and on the Ussuri. A distinct species. 



The insect described as L. cassiope, from a single female taken by 

 Maack, does not seem to have been discovered by later collectors, 

 and is thought by Dr. Staudinger to be an aberration of J^. nycteis. 



L. SIBYLLA, Linn. Syst. Nat. x. p. 781. 



Common in Japan, where it agrees very well with European 

 specimens ; but in Amurland Dr. Standing^ finds that the white 

 bands are always narrower.
