Show 886 MR. H. J. ELWES ON THE BUTTERFLIES [NoV. 15, ? THECLA W-ALBUM, Knoch, Beitnige, ii. p. 85 (1781). Found at Pekin {Bremer); a specimen from there is in the British Museum. Also at Shanghai (Pryer). Differs from the European insect 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-diuger'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. stygiana, 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 Domes. ?T. SPINI, Schiff. S. V.p. 186. Recorded by Bremer from Pekin, and by De l'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 {Radde), and by De l'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 aud 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. Staudinger's collection from Vladivostock {Christoph) which agrees perfectly with it. |
