species, considering it possible that the markings may be liable to variation. It is figured 
resting on a flower of the double variegated Japan rose, a scarce variety of the Camellia 
Japonica. 
In the Naturalist’s Library, Entomology, vol. 5, p. 89, this figure is given as the 
female of Priamus, although a figure agreeing with the present is likewise given under 
the name of Remus.

Ornithopterus: with the wings dentated; the anterior black, the posterior golden 
yellow, with a festooned black margin, and with a row of black submarginal 
spots, of which the two exterior are the largest, the others being often obsolete.

Originally described by Fabricius from the Banksian Collection and Mr. Jones’s 
drawings; and as the present figure exactly agrees with the Fabrician description, it is 
most probable that it was from one of these sources (to both of which Donovan had 
access) that this figure was taken. This is of some importance, as the species has been 
confounded with several others, as may be seen from the synonyms quoted above, and 
as it is liable to considerable variation in the spots of the posterior wings, and in the 
occasional paler radiation of the superior wings. In a specimen which I possess, 
exactly corresponding with this figure, the neck has a scarlet band, and there are some 
scarlet bands at the sides of the thorax beneath. 
The transformations of this species have been observed by Dr. Horsfield in Java, 
and figures of the larva and pupa published in the Lepidoptera J'avanica, (pi. 4, /. 13). 
The caterpillar is thick, of a yellowish colour, with, a broad dorsal white line. It is 
armed with eight rows of erect obtuse fleshy appendages, as well as with a furcate tubercle
