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. 



This 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 up|)er surface. The upper surface 

 of 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.

 (1865). 



Common about Yokohama {S. Pryer). I took it in July near 

 Nagahama, Lake Biwa. 



34. Dipsas lutea. 



Dipsas lutea, Hew. 111. Diurn. Lep. p. 67, t. xxvi. figs. 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 conspicu- 

 ously in colour, shape, and size from the other green Theclce ; 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
