Lepidoptera of Sikkim. 443 
459. Pithauria murdava. 
Hesperia murdava, Moore, P. Z. S., 1865, p. 784; L.c., 
1878, p. 689, t. xlv., fig. 13. 
Not uncommon up to 8000 ft. from May to October. 
460. Pithauria stramineipennis. 
Pithauria stramineipennis, Wood-Mason & de Nicé., 
J. A. 5S. B., 1886, p. 388, t. xv., 5, °s, 
P. murdava, Dist., Rhop. Mal., p. $78, t. xxxv., 9, 3. 
Differs from murdava in the lighter straw-colour, not 
yellowish olivaceous, as in murdava. It has been treated 
by Moore as the female of murdava, but the females of 
both species are known to de Nicéville, and are in my 
collection. That of murdava differs in having the darker 
wings richly purple-glossed, and in the very scanty 
setulose clothing at the base, conforming in colour to 
the male. It is also not uncommon at low elevations. 
461. Baoris oceia. 
Pamphila oceia, Hew., Desc. Hesp., p. 31, No. 22 
(1868). 
Hesperia oceia, Wood-Mason & de Nicé., J. A. 8S. Baa 
1881, p. 258. 
Baoris unicolor, Moore, P. Z S., 1883, p. 583; de Nicé., 
J, Ay Dobe 1668, t. x., fe. Lon 
B. scopulifera, Moore, l. ¢., p. 332. 
This species is the type of a genus in which the male 
has a conspicuous patch of velvety hairs on the centre 
of the hind wing. Both sexes vary very much in 
Sikkim, as in the Andamans. Of seven males in my 
collection, no two specimens agree in the number of 
spots. Of six females, three are spotless, as in unicolor, 
Moore; the other three have from five to eight spots 
on the fore wing. It seems incredible that Moore 
should have given two new names to this species without 
the slightest reference to the minute description of 
these variations given by Wood-Mason and de Nicéville. 
It is common up to 4 or 5000 ft. during the greater part 
of the season.
