Not rare in some of the mountain-districts of Central Japan, in July and August. The female is very scarce, and has, I believe, never before been described. "Expanse of wings about 1| inch, narrower than in the male; apex of wings produced to a much sharper point; ground-colour of all the wings black with a brownish tinge. In the centre of fore wings is an elongated bluish-white patch, and a fainter bluish-white crescent occurs on the hind wing starting from the costa ; fringes of fore wings black, of hind wings bluish grey. Under surface of all the wings uniform silvery white as in the male." 29. AMBLYPODIA JAPONICA. Amblypodia japonica, Murray, Ent. Mon. Mag. xi. p. 170(1875). This is a common species in Southern Japan in May. I took it also in Gensan, Corea, and again in Central Japan in the autumn. 30. AMBLYPODIA TURBATA. Amblypodia turbata, Butl. Ann. & Mag. Nat. Hist. ser. 5, vii. p. 133; P. Z.S. 1881, p. 855. This fine species seems to be very rare in Japan; I found it in May in the province of Satsuma flying in company with the last species, and there are specimens from Nikko in the National collection. It can be instantly distinguished from A. japonica by its tails. 31. NIPHANDA FUSCA. Niphanda fusca, Butl. P. Z. S. 1881, p. 883. Thecla fusca, Brem. & Grey, Schm. nordl. China's, p. 9 (1853) Men. Cat. Mus. Petr. i. t. iv. fig. 5 (1855). 5 . Amblypodia dispar, Brem. Lep. Ost-Sib. p. 24, t. iii. fig. 4 (1864). Polyommatus fuscus, Oberthiir, Et. Ent. ii. p. 20, t. iv. fig. 5. Common all over Japan and Corea in July and August; some specimens are much larger than others, but the markings and colour seem to be constant. 32. DIFSAS F L A M E N , Leech, nov. sp. (Plate X X X V I . fig. 2.) 5 . Expanse of wings If inch. Ground-colour of all the wings dull orange, deeply bordered round the costal and outer margins with black ; veins of the hind wings deeply marked with black towards the outer margin ; a small black spot occurs near the outer margin of the hind wing between the first and second submedian veins. Fringes short, dirty white. Underside of all the wings yellowish buff, outer margins bordered by a narrow black line. A submarginal band of bright orange elongated spots bordered on each side by a row of silver spots runs round all the wings, interrupted at the inner angle of the fore wing by a conspicuous black double spot. There is a small black dot |
