pure white and rich yellow as the male, differing chiefly in the absence of the 
subapical yellow spot on the fore wing below. Like the male it was always flitting 
up and down the sunny paths at ther edges of the wood, only alighting from time to 
time for a moment or two. Intermediate specimens occurred, and there was no 
possibility that the species could be different; but the forms were so unlike that 
they m ight almost claim to be called dimorphic.” Mr. H. J. Elwes records it as 
c; very common in Sikkim at low elevations, from 2,000 to 5,000 feet, from March 
to November ” (Tr. Ent. Soc. 1888, 418). Mr. L. de Niceville says it is “ one of the 
commonest butterflies in Sikkim, at low elevations, and flies from March to 
December ” (Sikk. Gaz. 1894, 169). Of the wet-season form we possess specimens 
from Manipur, taken by Dr. G. Watt; Nowgong, Assam (Mrs. Span); Cachar, 
taken in June; Sikkim and Bhotan (G. C. Dudgeon); Nepal (Gen. G. Bamsay); 
Bassein, Burma, April; Chittagong, October; Moulmein (W. S. Atkinson); 
Bhamo, November (Dr. L. Eea); and of the dry-season form {Varans) both sexes 
from Sikkim ; males from Chittagong, Burma, taken in January ; Moulmein, 
January; a Bhamo female, November (Dr. L. Eea) ; Chindwin, December; 
Col. C. H. E. Adamson took it at Mogoung, Burma, in January ; Dr. J. Anderson 
obtained it in “ Mergui, December; Thaing and King Islands in February ” 
(J. Linn. Soc. Zool. 1886, 49). In the British Museum are specimens of the wet- 
season form from Jorehat, June, Shillong and Sibsagar, Assam ; Manipur ; Bhamo, 
Pegu, Moulmein, Burma ; and of the dry-season form (Vacans ) from Maldah, Upper 
Bengal; Modah, Irriwaddy, Burma, March; Toungoo, March. Dr. N. Manders 
records “both sexes of the ivet-season form from Sawlon, but was not taken in the 
Shan States ” (Tr. Ent. Soc. 1890, 534). Col. Adamson records the sexes of both 
forms as “ exceedingly common in Burma” (List, 1897,43). Mr. J. Wood-Mason 
records <£ both sexes numerous in forests, in Cachar, from April to September” 
(J. As. Soc. Bengal, 1886, 372). 
The allied species u Hippo, Cramer, in Sumatra,” write Mr. L. de Niceville and 
Dr. L. Martin, “is a constant species, and does not exhibit the great seasonal 
dimorphism which is found in the Indian forms. It is found throughout the year, 
but only in or near the forest. The males often assemble twenty or thirty together 
on a small puddle on the road, the female is found in the forest hunting for flowers 
for herself, or for the food-plant of her larva. Dr. Martin has often seen them on 
the same flower that is frequented by the female oi - Udaiana Cynis. He has bred 
the butterfly from the larvae found feeding on a small shrub called by the Battaks 
e Daoen Tangla,’ which grows on the banks of rivers. The larva superficially does 
not greatly differ from the larvae of the Gatopsilias , but in shape is more slender. The 
pupa, however, is quite different, with a stellar indented thorax. The imago 
emerges in seven days” (J. As. Soc. Beng. 1895, 501).
