more in the form of macular bent lines and the vermilion 
spots near the margin are replaced by long vermilion 
streaks which extend from the outer line to the black-spotted 
outer margin. ‘The hind wings are white, but the marginal 
black band is broad at the apex and gradually fines down to 
the hinder angle, which it does not reach, and the large black 
knob to the marginal band near the hinder angle, so constant 
in pulchella, is altogether absent. In the antenne, however, 
is the greatest specific difference ; in pulchella and its close 
allies the antenne in both sexes are slightly fasciculate, whereas 
in this species they are strongly bidentate in the male, with 
minute hairs between the teeth, and slightly fasciculate in the 
female. 
Expanse of wings 1545 inch. 
Nicobars, Camorta. Three males and one female. 
Camptoloma flagrans, sp. Nn. 
3 ?. Very bright ochreous. Hind wings darker and 
brighter than the fore wings ; three black transverse lines in 
fore wing from the costa near base, from beyond the middle, 
and from near apex, all terminating on the outer margin near 
the hinder angle in a large red patch or smear, which is con- 
tinued in a streak or streaks along the hinder margin ; on the 
outside of this patch are two large black spots on the yellow 
cilia, marginal line and streak across end of cell also black. 
Hind wings without markings, as also is the underside, being 
of a uniform deep bright ochreous, with the three black lines 
and two cilia spots visible; anal tuft on abdomen pink. 
EXxxpanse of wings 1;%-17°> inch. 
Cherra Punji, Khasia Hills. One male, six females. 
Very closely allied to C. intertorata, Wk., from Japan, of 
which I have a long series; the red patch on fore wings is 
more diffuse and the cilia has only two large black spots, 
whereas in ¢ntertorata there are always three spots. 
Petosia euchana, sp. n. 
& ¢. Of a uniform sandy-yellow colour; palpi, head, and 
tip of abdomen bright ochreous, tip of palpi and antenne 
black. Fore wings with a black spot on the disk outside the 
cell and another below it on the submedian vein; in the 
female these spots are very much larger than in the male. 
Hind wings of male paler than the fore wings, with ochreous 
margin ; in the female the entire’wing is uniform ochreous. 
Underside: wings pale ochreous, unmarked in the male, with 
the spots showing through in the fore wings, and with central
