raddei Brem. stands entirely apart in facies; a remarkable species, which must be placed in the present genus as it agrees with the same in its morphologicalcharacters. Moore has erected for its reception a special genus, Aldania. Ground-colour white, dusted with grey-brown at the margins, the base and along the veins, the veins themselves blackish, a row of dark lunules along the margin, being especially distinct on the underside. — Amurland: Bureja Mts., Ussuri.
