 Polythrena miegata, Pouj. Ann. Soc. Eiit. Fr. 1895, p. 314, pi. vii. 



Male. Bright yellow, marked with black. Primaries 

 have a basal patch finely marked with yellow ; an angulated 

 fascia separated from basal patch by a thin angulated yellow 

 line ; central fascia indicated by an elongated patch on costa 

 and roundish patch on inner margin ; outer marginal border 

 deeply indented about the middle. Secondaries have a tri- 

 angular patch on abdominal margin, streaked with yellow 

 and spotted with the same colour on its upper edge ; there 

 is a large spot at anal angle, and the outer margin is bordered 

 from middle to apex. Fringes black, marked with yellow 

 below apex and from middle to inner angle of primaries ; on 

 the secondaries they are yellow marked with black from. 

 middle to anal angle. Under surface similar to above, but 

 the black triangular patch on secondaries is only indicated by 

 some disconnected spots.

 male.

Genus PLEMYRIA.

 Plemyria tibiale. 



Noctua tibiale, Esp. Noct. pi. clxiv. fig. 2 (1790). 

 Minoa Eversmannaria, Herr.-Sch. Suppl. fig, 443. 

 Eustroma tibialis, Meyrick, Trans. Ent. Soc. Lond. 1892, p. 71. 

 Odezia tibiale, Grasser^ Berl. ent. Zeit. 1888, p. 404. 

 There were eight specimens in Fryer's collection ; two of 

 these were labelled Yesso and one Oiwake. My native 

 collector took one example at Hakodate in June, and I ob- 

 tained the species at Gensan in July. 

 Graeser records it from Amur land. 

 Distribution. Europe; Amur; Corea ; Japan; Yesso. 

 In some specimens the white bands are very broad on all 

 the wings. This species is without the pencil of hair on 

 under surface of primaries, and cannot therefore be referred 

 to Eustroma. 



Plemyria hecate. 

 Melanippe hecate, Butl. Ann. & Mag. Nat. Hist. (5) i. p. 448 (1878) ; 



111. Typ. Lep. Het. iii. p. 55, pi. liv. fig. 12 (1879). 

 There was an extensive series from Oiwake in Fryer's
