LEPIDOPTERA. 



ventured to give it as a distinct 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. 



ORXITHOPTERUS HELIACON. 



Plate XIX. fig. 1. 



Species. Ornithopterus Heliacon : alis dentatis anticis nigris, posticis flavis limbo tenui

 Ornithopterus : with the wings dentated; tlie anterior black, the posterior golden 

 yellow, with a festooned black margin, and with a row of black snbmarginal

Originally described by Eabricius 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 Lepicloptera Javanica ( 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
