PIERINAi.

insect, very abundant in the wet season, but to be seen on the wing in every month. The under¬ 
side of this butterfly has a marked seasonal variation, similar in both sexes ; in the wet forms being 
almost plain yellow, in the dry forms darker yellow, with numerous white and reddish-brown mark¬ 
ings. The upperside of the $ in wet form has a very broad black border to the hindwing, the dry 
form has none, or hardly any marking; the upperside of the $ varies much, but in the wet forms the 
ground colour is generally almost white, with a broad and suffused dark brown border to the hind- 
wings ; occasionally almost the whole upperside is dark brown, except the diagonal white marking 
across the forewing and a slight patch of whitish on the anterior margin of the hindwing towards the 
base. In the dry form the ground colour of the upperside inclines to yellow, and there is little if 
any dark border to the hindwings. The wet forms are generally the larger but both sexes vary 
much in dimensions. 
The flight of this butterfly is strong and rather wild in the $ ; that of the $ is distinctly 
weaker. Although it is to be seen almost everywhere, it is addicted to wooded country. It is fond 
of some kinds of flowers, but rarely lingers at them, spending most of its time threading through 
jungle and manoeuvring about trees, now high up in the air, anon almost on the ground.

Egg, spindle-shaped, slightly ribbed longitudinally, yellowish-white ; attached singly either 
side of a leaf, but generally the upperside, of the foodplant of the larva. 
Larva, figured on PI. 3a, Fig. 17, pupa Fig. 18. Instead of being green, the pupa is 
sometimes very pale pinky-brown. The larva feeds on Capparis pumila , Champ., Nat. Ord. 
Capparidece ; a prickly, straggling shrub common in many places in this part of China, and also 
found in Sikkim and Khasia. 
Hebomoia glaucippe, Linn. 
This large and handsome insect is quite sufficiently numerous to be a feature of the but¬ 
terfly life here, and in habits is almost a large edition of Ixias , though its flight is perhaps even wilder 
and often very high. The underside of both sexes is much alike, and when the insect settles to rest on 
the underside of a leaf, dropping the forewings within the hindwings, it is very difficult to detect, 
especially when it chooses a bunch of withered leaves, as it commonly does. Commander Walker 
has observed that it is still better in keeping with its surroundings when drinking up moisture 
from damp sand ; a habit which is common to many butterflies, though I have never seen such 
swarms here on wet sand as have been observed in Borneo, Ceylon and other countries. 
Hebomoia is a very conspicuous object as it careers wildly about, and like many other 
butterflies, especially other Pierince , should the £ see any scrap of white paper or rag will imme¬ 
diately visit it, evidently mistaking it for one of its own kind. It is rather fond of flowers, but spends 
little time over them, chiefly sailing rapidly over and about trees and foliage. It is one of the few 
butterflies, except Hesperiidce , which seem able to extract nectar from the large and common 
purple convolvulus, Ipomcea palmata ) which has a very deep bell and evidently requires 
a long proboscis ; the Hesperiidce are able to creep right within the flower.
