a slender snow-white submarginal line ; fringe tipped with white : 

 head somewhat olivaceous; body greyish ; abdomen sordid brownish. 

 Wings below pale shining dove-brown, with white submarginal line, 

 white-tipj)ed fringe ; a diseo-submarginal series of white-edged black 

 spots and an irregular white-edged black discal line: primaries with 

 the discal line straight from the third subcostal to the first median 

 branch, where it is interrupted ; the disco-submarginal spots subconi- 

 cal, almost orbicular, increasing in size from the costa to the external 

 angle ; internal border white : secondaries with the discal line near to 

 the middle of the wing, oblique and terminating in a W-shaped 

 character ; the disco-submarginal spots lunate, the sixth interrupted 

 by a large orange spot with black centre, and the seventh divided by 

 an orange-and-black trifid streak which extends to the anal angle :

Iwashiro, second week in July. Coll. M. Fenton. 



Allied to T. eretria of Hewitson. 



Thecla butleri, Fenton. 



Allied to T. attilia ; colour the same ; margin of primaries 

 straighter. Above, the submarginal row of white spots in the se- 

 condaries larger and more distinct, the third, fourth, and the one near 

 the anal angle centred with black : below, the ground-colour slightly 

 duskier, becoming still more so towards the margin ; in the primaries is 

 a transverse bar in the middle of the cell, extending from the subcostal 

 to the submedian vein, and almost divided by the median into two 

 spots ; the discal bar ceases abruptly at the third median veinlet ; an 

 extra small spot, just on the division between the middle and apical 

 thirds, between the third median veinlet and the submedian vein : se- 

 condaries with a transverse row of three black spots at the base in a 

 descending series from the costal vein, a short bar at the end of the 

 cell as in primaries ; a transverse irregular bar in the middle third, ex- 

 tending from the costal and narrowing towards the independent vein ; 

 a row of three oblong spots, the first two with the longer axis placed 

 transversely, the third near the inner edge, almost at right_ angles to 

 the second ; a submarginal row of whitish spots centred with black, 

 more distinct and enclosed in the aforesaid dusky colour ; the orange- 

 red at the base of the tail and at the anal angle more suffused. Expanse 

 of wings 1 inch 3^ lines. 



Middle of August. Coll. M. Fenton. 



On the top of the peak, 1060 feet high, overlooking Hakodate, I 

 took one specimen that had become involved in a circular wind ed- 

 dying round the mountain and carried upwards in company with 

 numbers of Papilio hippocrates, Papilio maackii, Pieris megamera, 

 Neope fentoni, Satyrus bipimctatus, Argynnis paUescens ', Thecla 

 japonica, Lycana ladonides, and Lyccma hellotia — all more or less 

 'shattered ; some ascended still higher, until they were lost to view. 



Thecla regina, Butler. 



$ . Allied to T. quercus of Europe and T.fasciata of Japan. Pri- 

 ' Possibly A. locuples. — A. G-, B.
