Hyperaeschra biloba. 
Drymonia biloba, Oberth., Etud. d’Ent., v, p. 63, pl. viii, 
fig. 1 (1880). 
Semidonta biloba, Staud., Rom. sur Lép., vi, p. 358 (1892); 
Staud., Cat. Lep. pal., i, p. 109 (1901). 
Seven male specimens taken in the following localities : 
Tobetsu and Junsai Numa, Oshima, Yezo, July, 1902; 
Nikko, July, 1893; Yoshino, Yamato, July, 1898, 1894. 
Staudinger in his catalogue (supra) states that this 
species is similar to Hyperaeschra basalis, Moore, which 
is figured on p. 165 of Hampson’s “ Moths of British 
India,” vol. i. The angulation of the postmedial line on 
the forewings differs in the two species, and Jiloba is 
smaller in expanse. My specimens of biloba measure 40 mm. 
to 44 mm., whilst basalis measures 50 mm. in expanse. 
Hitherto unrecorded from Japan.
