Expanse. — IJ^ inches. 



Holotype. — 9, Sapporo, Hokkaido, Japan, July 18, 1916, (S. Kuwayama). 

 Type in the collection of the author. 



On account of its broad wings, this species resembles a certain form of 

 Pieris napi L., and in fact it has often been so identified. In his list of the 

 butterflies of Hokkaido, Mr. S. Kuwayama refers to this species as P. napi 

 saying that it is not rare in that Island, but not found in the Main Island of 

 Japan. In reality, this species belong to the genus Leptidia, as can be easily 

 told by the small size of the discal cells of the wings. 



Polygonia asakurai, n. sp. 



\'ery close to P. c-albiim L.; black markings above generally heavier; a 

 distinct black belt in the limbal area of hind wing; the white mark in middle of 

 hind wing beneath \^-shaped, with its arms widely open. 



Male. — ^Fore wing above fulvous with an elongated black patch across the 

 cell and at the end a larger patch of similar shape; an elongated sub-apical 

 patch on the costa and one on the inner margin well separated; a row of three 

 round spots running from the inner margin toward the lower end of the sub- 

 apical patch, the first spot, which is cut by the vein II, being the largest; outer 

 border blackish brown. Hind wing fulvous with three conspicuous black 

 patches of about the same size in the discal area; a row of black spots forming a 

 belt in the limbal area, running from the costal margin toward the anal angle; 

 this belt and the dark brown outer border enclose a submarginal row of fulvous 

 spots. Underside marbled with various shades of brown and ochre, and streaked 

 with fine dark brown lines; the discal band across the wings irregular and in- 

 distinct. Fore wing with a grayish white patch on the costa externally to the 

 discal band; a row of elongated olivaceous spots before the outer margin. The 

 similar olivaceous spots less distinct in hind wing; a limbal series of round 

 olivaceous spots; the discal band marked with an interrupted wavy black line 

 on each side; the white mark in the middle V-shaped, with its arms of about 

 equal length opening widely to form an angle of about 135 degrees. 



Expanse. — 1^/4 inches. 



Holotype, — 9, Horisha, Formosa, (K. Asakura), April 23, 1919. Type in 

 the author's collection. 

 Oeneis pseudosatyra, n. sp. 



Related to 0. nanna Men.; wings wood brown; eye-spots pupiled with 

 purplish white. Hind wing beneath without eye-spots; an ill-defined dark 

 wav^y belt accompanied by a grayish cloud- across the wing; no grayish markings 

 in the basal area. 



Male. — Upperside of fore wing wood brown, darker toward the base; an eye- 

 spot, pupiled with purplish white, in the 2nd, and a larger one in the 5th inter- 

 space; ])rownish ring around the eye-spot indistinct. Hind wing similarly 

 cojoured, with four eye-spots similar to those of fore wing, the eye-spot in the 

 4th interspace much smaller than others, the one in the 2nd interspace being 

 the largest, l^nderside a little lighter. Fore wing with the eye-spots of the 

 upperside repeated; a faint dark submarginal line, and another one across the 

 limbal area; a short, dark bar at the end of the cell ; a grayish patch at the apex, 

 whence it extends in a very narrow line half way along the outer margin. Hind
