Show 1887.] OF JAPAN AND COREA. 409 In one spot near Nagahama (Lake Biwa) I found the forms described as poliographus, simoda, subaurata, and elwesii all together and of six pairs which I took in copula and kept separately labelled, only two pairs were of the same form, viz., simoda; the remainder were as follows :- 2 cases of simoda rf and elwesii $ . 1 case of subaurata $ and elwesii § . 1 case of simoda S and poliographus $ • The inference is that they belong to the same species; otherwise they hybridize in a manner totally unprecedented and highly improbable. The type oi pallens is such a bad specimen, that it is impossible to say what it is. 24. TERIAS L^ETA. T. lata, Boisd. Sp. Gen. i. p. 674. Var. jaegeri, Men. Cat. Mus. Petr. p. 84, t. ii. fig. 1 (1855). T. subfervens, Butl. A common species in spring and autumn all over Southern and Central Japan. A series in the National collection labelled subfervens, Butl., do not differ materially from Japanese specimens, and some of the Northern Indian forms are not separable. Mr. H. Pryer says that it occurs all through the summer. 25. TERIAS BETHESBA. T. bethesba, Janson, Cist. Ent. ii. p. 272 (1878). This species, which is very distinct from the other Japanese Terias, occurs in Central and Southern Japan in May and again in August. 26. TERIAS HECABE, Linn. T. hecabeoides, Men. Cat. Mus. Petr. i. p. 85, t. ii. fig. 2. T. sinensis, Luc. Rev. Zool. 1852, p. 429. T. mariesi, Butl. Trans. Ent. Soc. 1880, p. 198, t. vi. figs. 1-7. T. anemone, Feld. Wien. ent. Mon. vi. p. 23 (1862). T. mandarina, de l'Orza, Lep. Jap. p. 18 (1869). T. hobsoni, Butl. P. Z. S. 1880, p. 668. T. hybrida, Butl. Trans. Ent. Soc. p. 199. T. connexiva, Butl. Trans. Ent. Soc. p. 199. Common all over Southern and Central Japan, and recorded from S E Corea. It is needless to say anything about this well-discussed question, as Mr. H. Pryer has settled it in the most conclusive manner by breeding all the forms known from Japan, from eggs laid by the same parent. 27. MILETUS HAMADA. Miletus hamada, Druce, Cist. Ent. i. p. 361 (1875). I found this species common all up the west coast of Central Japan • it also occurs at Nikko. It seems fond of water, and flew about amongst the thick bamboo-grass on the banks of streams in July and August. |
