Show 412 MR. J. H. LEECH ON THE BUTTERFLIES [May 3, T. orientalis and T. japonica, which is quite possible, but his views require verification. 38. THECLA JAPONICA. T. japonica, Murr. Ent. Mon. Mag. xi. p. 169 (1874). T. taxila, Brem. Lep. Ost-Sib. t. viii. fig. 2. T. regina, Butl. P. Z. S. 1881, p. 853. T. fasciata, Janson, Cist. Ent. ii. p. 272, t. v. fig. 4 (1874). Ab. b. T. aurorina, Oberthiir, Et. Ent. v. p. 18. Occurs all over Japan and at Gensan in June and July. There are four distinct forms of female, none of which are rare:- a. Uniform brown throughout. fi. With a fuscous patch on fore wing. y. With a blue patch containing a fuscous mark. ^. With a blue patch. Besides these forms all the intermediates occur. The Corean specimens are rather smaller than the Japanese form ; and in Yesso, and also at high altitudes in Central Japan, occurs a boreal form which is quite similar to the usual type, only on a much smaller scale. I have a series also from Amurland which are identical and present similar variations of the female. Dipsas taxila, Hew. 111. Diurn. Lep., Suppl. p. 16, t. iv. figs. 17. It is absolutely impossible to say which species this is intended for, as the plate is very inferior and the description insufficient. A series of T. orientalis are in the Hewitson collection under the name of T. taxila, and Oberthiir considers the figure and description to represent T. smaragdina. 39. THECLA SIGNATA. T. signata ,Butl. P. Z. S .1881, p. 854 ; Aid to Identif. of Ins. pl. 114. The type of this species is in Mr. Fenton's collection; it is in bad condition. The fact of the ceil of the hind wing being filled in with violet separates it at once from any known Japanese species. I take the type to be a female, and should not be surprised if it had a green male. Recorded from Kuramatsunai, August. 40. THECLA ARATA. T. arata, Brem. Lep. Ost-Sib. p. 25, t. iii. fig. 6. Does not seem to be common; I took it at Hakodate in August. It is also recorded from Central Japan. 41. THECLA TYRIANTHINA. T. tyrianthina, Butl. Ann. & Mag. Nat. Hist. ser. 5, vol. vii. p. 34, t. iv. fig. 5. I took this species at Gensan in July. It is very distinct from T. arata; on the upper surface it is darker and on the underside it |
