Heterocerous Lepidoptera from Japan. - 181 
This species has somewhat the facies of Semiophora 
gothica, but the antenne of the male are simple. 
ORTHOSIIDA. 
60. Cerastis levis, N.S. 
Primaries above dark silky chocolate-brown, varied by 
velvety brown lines and spots, the whole of the dentate- 
sinuate lines across these wings arranged as in C. erythro- 
cephala of Europe, those which bound the central area 
on each side being formed of rather more widely 
separated parallel double lines ; external border shining 
dark ash-grey almost to apex, and with a pale internal 
limiting line ; its apical portion testaceous ; costal border 
crossed by numerous parallel oblique velvety brown 
dashes; marked beyond the middle by four equidistant 
white dots; orbicular spot outlined in brown, below it 
and touching the median vein and the inner limit of the 
central area is a rather large velvety-brown spot ; reni- 
form spot duplicated, the inner spot being merely out- 
lined in brown, the outer one almost lunate in form, and 
straw-yellow ; nervures on the dise dotted with black ; 
fringe greyish, with central and basal undulated brownish 
paler lines ; secondaries whity brown, sericeous, ereyish 
in certain lights; costal border whitish, silvery at base ; 
a diffused greyish external border ; fringe traversed by 
two grey lines, and tipped with silvery white ; thorax 
chocolate-brown; abdomen whity brown; wings below 
pale shining pinky brown, crossed by an irregular grey 
discal line and irrorated with grey towards the costal 
margins; primaries with the central area broadly 
ereyish, the internal border whitish, with brassy re- 
flections ; body below pinky brown; expanse of wings, 
1 inch 9 lines. 
Tokei (Menton). 
61. Cerastis subdolens, ni. 8. 
Nearly allied to C. erythrocephala, but larger, less 
sericeous, varying in the colour of the primaries and 
thorax from laky brown to pale sandy flesh-tint, whereas 
the European species varies from shining chocolate- 
brown and grey to reddish clay-coloured ; the reniform 
spot larger and paler, sometimes almost entirely yellowish 
white ; there is also invariably a small submedian black
