the tails are shorter, and the black tail-spot round, not elon-

with dark chocolate-brown, the markings all well separated, 
showing the pure white ground-colour between them; the 
bands on both wings darker than in bfasczata, the transverse 
bands not so broad, but broader than in falka; the shape of 
the tail and spots similar ; the abdomen, except at the base,

Thinopteryx crocopterata assamensis, nov. 
3 ¢. Markings similar to crocopterata, Kollar, from the 
N.W. Himalayas, of which I have both sexes, but the colour 
is quite different, being dark orange in both sexes, whereas 
the colour of crocopterata is yellow in both sexes (“flavis 
eroceo maculatis’’): assamensis is a very common form in 
the Khasia Hills; I have received very many specimens, 
Expanse of wings, ¢ 2, 24 inches. 
Hab. Assam, Sikkim. : 
Thinopteryx crocopterata padanga, nov. 
g. Coloured like assamensis; markings similar, but the 
postmedian band of the fore wing and the submarginal band 
of the hind wing is darker and much broader and not so 
close to the margin; the basal half of the fore wing is 
suffused with brown strie; the medial patch on the hind 
wing is very much more enlarged and runs down to the 
abdominal margin, and the tail at vein 4 is entirely dark 
brown, this colour expanding until it reaches the submarginal 
band. Underside with the ground-colour pale as in assam- 
ensis, but the hands are much broader and the outer two- 
thirds of the wing up to the submarginal band is greyish 
brown. 
Expanse of wings, ¢, 24 inches.
