bounded by a small black spot ; a broad orange patch, in continuation of tho discal spots, at 

 anal angle, its inner edge bounded by two slender black litura) ; a large submarginal black 

 spot on the inner half of the orango patch, which is bounded by the first median interspace 

 and two black marginal spots in tho angles of the outer half, upon interno-median inter- 

 space ; these two spots are connected by a silvery -blue line ; all the wings with a black 

 marginal line ; fringes snow-white, spotted with black. Body below snow-white ; legs 

 banded with black. Expanse of wings 1 inch 9 lines. 

 " Ibara Pass, Dcwa, 2nd week of July. Coll. M. Fenton." {Butler, I. c.) 



This appears to bo a very rare species, and has only been observed in 

 Japan. 



The specimen from Nikko referred to by Pryer {I. c.) is now in my 

 possession. It is of the same sex as the type, but differs from the figure in 

 ' Aid ' in its narrower wings, and in having a pale brownish shade on disc of 

 primaries ; the tails of secondaries are shorter and broader, and the under 

 surface is not so green. 



Zephyrus stygiana. 



Thecla stygiana, Butl. Aun. & Mag. Nat. Hist. (5) vii. p. 35, pi. iv. fig. 6 (1881). 



"Above smoky brown, without markings. Wings below greyish brown, with an indistinct externo- 

 discal series of blackish spots bounded outwardly with yellowish ; primaries with an 

 indistinctly whitish-bordered black spot at external angle ; secondaries with a very indistinct 

 submarginal series of dusky spots : a patch of orange at external angle, enclosing a black 

 spot above the tail, which is also black ; anal angle black ; pectus bluish white ; venter 

 sulphur-yellow. 



" Expanse of wings 1 inch 7 lines. 



" Nikko, Central Japan {Maries)." {Butler, I. c.) 



This seems to be a very rare species. Pryer does not refer to it in his 

 ' Rhopalocera Nihonica,' and so far as I am aware there is but one specimen 

 known ; this is the type in the National Collection at South Kensington. 



Zephyrus enthea. (Plate XXX. fig. 18, var.) 



Thecla enthea, Janson, Cistula Entom. ii. p. 157 (1877) ; Pryer, Nilion. p. 15, pi. iv. 

 fig. 12 (1886). 



" Above dark brown, disc of primaries lighter ; secondaries with one long tail, white at its apex ; 

 beneath white ; primaries with seventeen conspicuous black spots, arranged thus — two near 

 the base, the upper one large, one at the eud of cell, three in an oblique row on the costal 

 margin beyond the middle, and an irregular transverse row of five, followed by a submarginal 

 row of six ; apical margin rather broadly brown ; secondaries with three spots in a row at the 

 base, a small one in the cell, an elongate one at its end, a similar-shaped one between it and 

 the anal angle, three along the abdominal margin, a curved transverse row of six beyond the 

 middle, and a submarginal row of five, those at the base and near the costal margin black,
