Yokohama (H. Pryer). 
58. Apamea nivalis, n. s. 
Primaries above snow-white, sericeous ; markings as 
in A. gemina, excepting that they are of a paler cupreous- 
brown colour, and that the markings are absent from the 
interno-basal area; costal border cupreous-brown, crossed 
by numerous white-edged black dashes; secondaries 
shining creamy white, like tarnished silver ; body above 
silvery white, the abdomen becoming slightly greyish 
towards the anal extremity; under surface shining 
creamy white ; expanse of wings, 1 inch 2 lines. 
Tokei (Fenton). 
This pretty little species seems to be most nearly 
allied to A. demissa of Canada, with which it agrees in 
general pattern, the most prominent markings on the 
primaries being the large subquadrate patch crossing the 
outer half of the cell, and the bimaculated slightly dusky 
- outer border; in size it agrees better with A. modica 
(= Celena subcedens) of Trenton Falls; its natural 
position would probably be between these two forms. 
54. Perigea ? argyrosticta, n. 8. 
Allied to P. hylea of S. America ; primaries above red- 
brown, with bright cupreous reflections; basal area 
varied with bright orange; an abbreviated elbowed 
whitish line across the centre of the basal area ; the area 
between the subbasal line and the inner line of the 
central belt occupied on the costal border by a large 
unequally quadrate yellowish spot; ordinary lines very 
irregular, divergent above the first median branch, pink, 
with blackish edges ; orbicular spot small, reddish orange
