Heterocerous Lepidoptera from Japan. 7 
paler than in 8S. seriatopunctata, with the same black 
spot at the end of the cell, but the other spots differently 
placed, being in the interno-median and first median 
interspaces ; expanse of wings, 1 inch 7 lines. 
One male. Tokei (Fenton). 
Our males of S. seriatopunctata measure four lines 
more in expanse than this species, but the whole colora- 
tion is so distinct, notwithstanding a partial agreement 
in the pattern, that I can hardly believe it possible for 
the difference to be due to variation. 
10. Spilarctia bifasciata, n. s. 
Buff-coloured, the primaries crossed at basal third by 
an arched and unequal macular band commencing on 
the costa in a cuneiform black dash which runs almost 
to the base; a second more uniform band, elbowed at 
the inferior angle of the cell, and only separated by the 
buff-coloured nervures just beyond the middle; this band 
commences in a costal dash which runs towards the 
apex, a rather broad internal abbreviated band uniting 
the two transverse bands; antenne black; abdomen 
with dorsal and lateral series of black spots; under 
surface bright ochreous, the bands of the primaries 
indistinct ; expanse of wings, 1 inch 11 lines. 
One male. Tokei (Fenton). 
I do not know any species nearly allied to this. 
11. Euprepia pheosoma, Butler. 
Var. auwripennis. 
Differs from the typical form in having the ground- 
colour of the secondaries and abdomen bright golden 
ochreous instead of scarlet; expanse of wings, 3 inches 
1 line. 
One female. Tokei (Fenton). 
I find, from an examination of four specimens of the 
typical form from Nikko and two from Tokei, that the 
coloration of the body agrees as a rule with the Euro- 
pean EH. caja; the species may, however, be invariably 
separated from the latter by the great breadth of the 
oblique belt from the inner margin to the end of the cell 
of primaries, which, unlike that in H. caja, always greatly 
exceeds in width the band from the end of the cell to the
