The pupa is attached by the tail and a central band, about 

 Ij inch in length and throughout of a pale green, finely 

 speckled with darker. Over the head there is a projection or 

 process of considerable length, from which emanate four con- 

 spicuous brown lines, which proceed two on each side until 

 they meet at the tail. 



This species is common in open sunny places, such as 

 gardens and waste grounds where flowering-plants occur. 

 Its food is the camphor-laurel, on which the parent insect 

 deposits the eggs singly. 



Owing probably to the copious rains which have fallen 

 during the past summer and the consequent luxuriant vege- 

 tation Papilio sarpedon and many other butterflies have been 

 unusually abundant. One conspicuous species, Delias argen- 

 thona^ never before observed by the Sydney collectors, has 

 been comparatively common. It will be interesting to see if 

 the species has permanently established itself; in Queens- 

 land it is one of the most abundant of the Pierinai, but 

 hitherto, [ believe, the Clarence E.iver has been the southern- 

 most limit of its rano-e.

The young larva of this species, which I found in April 

 feeding on the tender shoots of the orange, is whitish in 

 colour, with the sides velvety brown ; the liead, second, third, 

 eleventh, and twelfth segments black ; each segment except 

 the first and last provided with small, black, bifid bristles • 

 the first, second, third, and last segments with large black 

 tubercles. At the first moult the larva loses the bifid bristles 

 and the tubercles assume the appearance of black spines, the 

 anal one white at the base and bifid ; the larva is now of a 

 delicate green colour, somewhat speckled, with the head yel- 

 lowish green, the anterior segments pale yellow, and tlie tail 

 reddish. After the second moult, wliich took place in about 

 a week from the time of hatching, it became perceptibly 

 larger and more brightly coloured ; the head turning 

 yellowish green and the anterior spines, together with the 

 space between them, reddish black. It is in this stage I 

 believe, but on this point I am not quite sure, that the retrac- 

 tile tentacula are first perceptible ; they are long, soft, and 

 greenish in colour. At the third moult the ground-colour is 

 much yellower and the green more pronounced, with two 

 distinct rows of white spots on each side, the spines less con- 

 i-picuous, and the anal horu yellow, tipped with black, and
