852 MR. A. G. BUTLER ON BUTTERFLIES FROM JAPAN. [NoV. 15, 



but we have what I take to he the species in the Museum : our ex- 

 ample has a very unusually prominent submarginal series of broad 

 dusky lunules on the under surface. 



Lyc^na iburiensis, Butler. 



Allied to L. argus, but more nearly of the size and colour above 

 of L. lycaumas. Pale silvery blue with brown veins and broad smoky- 

 brown external borders ; fringe very narrow and snow-white ; secon- 

 daries with broad brown costal area ; body above rather darker than 

 the wings : under surface chalky bluish white ; the base, especially in 

 the secondaries, suffused with pale bluish green ; black spots arranged 

 as in L. arqus, but large and intensely black ; the orange lunules 

 wanting ia the marginal ocelloid spots of the primaries, paler in those 

 of the secondaries; no metallic pupils to the black spots of the se- 

 condaries ; pectus bluish. Expanse of wings 1 inch 5 Hnes. 



Iburi, Hokkaido ; July. _ Coll. M. Fenton. 



A very distinct and pretty species. 



Thecla ibara, Butler. 



2 . Upper surface similar to T. mera, sericeous fuliginous brown : 

 primaries with broad diffused blackish external area and costal bor- 

 der ; fringes snow-white, spotted with black at the extremities of the 

 veins : head olivaceous varied with snow-white. Under surface of wings 

 golden stramineous ; a discal series of black-edged orange lunate spots 

 followed by a series of oval pearl-white spots from the upper radial 

 of primaries to the second median branch of secondaries, the third 

 and fourth of the primaries bounded externally by a few black scales, 

 the fifth (or last) on the primaries bounded by a large black spot, 

 the orange lunule also almost wholly covered by its black border ; 

 the fifth and last of secondaries bounded by a small black spot ; a 

 broad orange patch, in continuation of the discal spots, at anal angle, 

 its inner edge bounded by two slender black liturse; a large submar- 

 ginal black spot on the inner half of the orange patch, which is 

 bounded by the first median inters]iace and two black marginal spots 

 in the angles of the outer half, upon interno-median interspace ; 

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

 with a black marginal line ; fringe snow-white, spotted with black. 

 Body below snow-white ; legs banded with black. Expanse of wings 

 1 inch 9 lines. 



Ibara pass, Dewa, second week of July. Coll. M. Fenton. 



This on the under surface is one of the most beautiful of the true 

 Theclce. 



Thecla orsedice, Butler. 



5 . Upper surface much like the females of lolaus pseudolonginua 

 and Pithecops intensa. Primaries pale bluish grey, or greyish white, 

 with very broad black-brown apical area and external border ; median 

 branches brackish ; costal border pale bronzy brown, faintly shot 

 with violet ; fringe tipped with white : secondaries fuliginous brown, 

 with the abdominal area and discoidal cell washed with pale ash-grey ;
