LEPIDOPTERA INDIOA. 
ground-colour creamy-white,' the basal and marginal area very pale yellowish- 
ochreous, or pale greyish-ochreous, the basal area being also delicately tinted more or 
less with very pale olive-green; basal and marginal markings as in wet-season form, 
but more or less indistinctly-defined, and all of a pale ochreous, variable in shades of 
intensity in certain specimens, and defined with whiter borders. Underside white 
with a delicate pinkish flush; markings as above, pale ochreous, but more or less ill- 
defined ; marginal ocelli and anal spot black. 
Expanse, S ? 2 to 2^ inches. 
Habitat. —Sikkim ; Bhotan ; Khasias; Silhet; Orissa; Burma; Siam ; Tenas^ 
serim ; Andamans ; Malay Peninsula. 
Distribution.— “ Extremely rare in Sikkim, which is probably the westernmost 
limit of its range; single specimens have been taken at Singla and Sivoke, at low 
elevations in the spring and autumn. The difference in coloration observed in 
this species may be due to seasonal causes. Mr. Gr. C. Dudgeon has observed that 
the green form .occurs in March and the brown form from August to September” 
(de Niceville, Sikkim Graz. (1894), 146). We possess a pale-coloured male of the 
brown form from Bhotan, taken by Mr. Dudgeon. Mr. de Niceville records specimens 
of both the white and brown forms from Khurda in Orissa, Tenasserim, Andamans, 
and Perak (Butt. Ind. ii. 254). Numerous specimens of both forms have been 
received by Col. C. Swinhoe from the Khasias. The type specimen is recorded, by 
Pabricius, from Siam, and is still in the Banksian Cabinet in the British Museum. 
Mr. P. Crowley possesses a male of the brown form identical with the type, also 
from Siam, and a pale-coloured male of the brown form from Shillong. Col. C. H. E. 
Adamson obtained the pale form “ near Moulmein, on the Hlinebwe Biver ; but rare ; 
in August and February” (List, 1897, 26), and says, in epistola , “that when flying 
it may be mistaken for Junonia Atlites , which was exceedingly common at the 
same place.” Dr. N. Manders obtained the pale form in Eastern Karenee, Burma 
(Tr. Ent. Soc. 1890, 525). A male and female of both forms from the Andamans 
and Perak are in Mr. P. Crowley’s collection. . A female of the pale form from 
Salanga Island is in the British Museum. We possess a female of the pale form from 
Hainan. In the numerous specimens of both the wet and dry-season forms we have 
under examination we observe various degrees of shades in the intensity of the 
colour of the basal and marginal area and markings, which evidently show a grada¬ 
tional mergence from one form to the other. 
Of our illustrations of this species on Plate 308, figs. 1, la, b represent a male 
and female of the ivet-season form from the Khasia Hills, identical with the Fabrician 
type of Codes in the British Museum, and figs, lc, d, e, a male and female of the 
dry-season form; fig. lc, being a Burmese male, and fig. Id, e, an Andaman 
female.
