Show 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 band on the hind wings reduced to a line of spots margined with white. LIMENITIS HELMANNI, Lederer, Verh. zool.-hot. Gesellsch.Wien, 1853, p. 356, t. i. fig. 4. Found at Askold, Blagovetschensk, Onon, the Ussuri, and also, according to De l'Orza, in Japan, though I have seen no specimens from there. Specimens from the Altai have the bands and spots narrower than Amur specimens. IL. HOMEYERI, Tancre, Ent. Nach. 1881, p. 120. Seems to m e 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 Baddefskaia, Blagovetschensk, and the Ussuri. L. AMPHYSSA, Men. Schrenk's Reise, p. 21, t. iii. fig. 1. Found in many parts of the Amur region, and, according to De l'Orza, 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. latifasciata, Men. Schrenk's Reise, p. 30, t. iii. fig. 1. De l'Orza says that Japanese specimens (which, however, I have never seen) hardly differ from Altai specimens. This is probably an error, as L. sydyi has not been found on the Amur, and the variety L. latifasciata is very distinct in all the specimens I have seen, having the white bands on both wings nearly twice as broad as in typical //. sydyi. Indeed, if no intermediate forms occur, I think it might fairly be separated. L. POPULI, Linn. Syst. Nat. x. p. 476. 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 localities at least, usually of the form known as LJ. tremula, Esp. 114. L. NYCTEIS, Men. Schrenk's Reise, p. 28, t. ii. fig. 11. Athyma 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 L. nycteis. L. SIBYLLA, Linn. Syst. Nat. x. p. 781. Common in Japan, where it agrees very well with European specimens; but in Amurland Dr. Staudinger finds that the white bands are always narrower. |
