274 Mr. A. G. Butler on new 
Lithosiide. 
1. Nola gigas, sp. nov. 
Belongs to the N.-strigula group, but is more nearly allied 
to N. fumosa; smoky grey, the primaries paler than the 
secondaries, but densely irrorated with grey scales, and glossy ; 
the lines much less distinct than in N. strigula, the spots on 
the fringe less defined; the embossed spots on the discoidal 
area strongly marked ; base of costal area blackish. Expanse 
of wings 34 millim. 
Yesso. 
Possibly allied to N. gigantula of Staudinger from Asia 
Minor ; but the description of that species states that the lines 
across the primaries are more distinct than in N. sérigula, 
the reverse being the case in the present species. 
Acontiide. 
2. Chasmina atrata, sp. nov. 
Nearest to C. nervosa, of the same size, but the wings dark 
bronze-brown, with the base of primaries, excepting at costa, 
and the interno-basal area of secondaries snow-white, slightly 
opaline ; fringe with the basal half grey and the external half 
white: body snow-white, antenne dark brown. Wings below 
nearly as above, but the basal half of primaries irrorated with 
white in continuation of the white basal area of the upper 
surface ; the basal half of costal border of secondaries white, 
and the centre of the wing irrorated with white scales: body 
below white; under surface of antennee and proboscis casta- 
neous. Expanse of wings 27 millim. 
Yesso. 
This species can be at once identified by its coloration, all 
the forms hitherto recorded being snow-white, C. nervosa only 
having the veins brownish. 
Hypogrammide. 
3. Gerbatha pseudodyops, sp. nov. 
Nearly resembles the New-World Dyops ocellata in general 
coloration ; agrees in the position and outline of its markings 
with Xylophasia scolopacina, with which I should have con- 
sidered it congeneric but for its more slender body and smaller 
palpi; the general coloration of the primaries is slaty grey,
