Show 1887.] OF JAPAN AND COREA. 411 between the fifth orange spot of the fore wing and the margin, and a row of three black spots near the anal angle of the hind wing. ihis species is allied to Thecla raphaelis, and michaelis, Oberthiir. it agrees with T. raphaelis in the absence of tails and in the design of the underside ; it is, however, much larger and there is a larger proportion of black on the upper surface. The upper surface ot the fore wing agrees with T. michaelis. I only succeeded in taking a single specimen of this species, which was flying over small trees near the monastery of So-ko-San about 14 miles N.W. of Gensan, on June 15, 1886. 33. DIPSAS S.EPESTRIATA. Dipsas scepestriata, Hew. 111. Diurn. Lep. p. 67, t. xxvi. figs. 7, 8 (1865). Common about Yokohama (H. Pryer). I took it in July near Nagahama, Lake Biwa. 34. DIPSAS LUTEA. Dipsas lutea, Hew. 111. Diurn. Lep. p. 67, t. xxvi. fig-s. 9, 10 (1865). ° I took this, together with the next species, near Hakodate in August; it occurs also in Central Japan. 35. DIPSAS JONASI. Dipsas jonasi, Jans. Cist. Ent. ii. p. 157. This rare species occurs in Yesso. I took it in August flying about small trees. 36. THECLA ORIENTALIS. T. orientalis, Murray, Ent. Mon. Mag. xi. p. 169 (1875). Occurs plentifully all over Japan and at Gensan during the end of June, July, and the beginning of August. It differs conspicuously in colour, shape, and size from the other green Thecla; the female is variable in colour and markings, and the bar-markings on the centre of each wing on the underside are liable to be either partially or totally absent. 37. THECLA SMARAGDINA. T. smaragdina, Brem. Lep. Ost-Sib. p. 25, t. iii. fig. 5. T. taxila, Brem. Lep. Ost-Sib. p. 26, t. iii. fig. 7. This species, which occurs in Yesso, and I believe at Nikko, occupies an intermediate place between T. orientalis and T. japonica, from the latter of which it differs in the bar mark of the fore wing on the underside, which mark, however, Mr. Elwes says is not a constant character in the female. As it is not constant in either sex of T. orientalis, I fail to see how any great importance can be attached to it. The colour of the underside varies according to the condition of the specimens, the old ones being much paler than freshly emerged examples. Mr. H. Pryer is of opinion that this insect is a hybrid between |
