the superior wing, by the much lesser green discal spot, and by 

 the contiguous macular baiid being separated into two : by the 

 females in the several markings of impure white being very much 

 smaller and by the tear-shaped spots being of different form, 

 with their centres more occupied by dark-brown. 



From the 0. Euphorion, (of which the female is only known) 

 it differs by the faint white band in the discoidal cell and by the 

 streak between the fourth and fifth sub-costal nervules of the 

 primary wings not containing within it the small black spot, so 

 minutely detailed and figured in ihe Brit. Miis. Cat. p. 4, pi. 2, 

 fig. 3, as characteristic of the Euphorion; by the whole surface being 

 much more obscure ; and by cax-rying on the thorax the green 

 longitudinal stripe — not seen in any of the specimens of the 

 Euphorion, collected by the late Allan Cunningham, — nor in 

 those now in the cabinet of Mr. W. MacLeay. 



From the 0. Richmondia, it differs by being much larger ; by 

 the males showing on the upper surface of the anterior wing more 

 distinctly the inner marginal green border, and on the under 

 surface a much smaller green discoidal marking : by the females 

 possessing the tear-shaped markings more occupied by the dark- 

 bi'own spots within them ; by the more general sombre appear- 

 ance ; and by the green stripe on the thorax. 



From the 0. Poseidon (of which the male is only known) it 

 differs by not exhibiting " the rich green colour which extends 

 along both sides of the median nervure and partly, or, entirely 

 along the course of the nervules of the primary wings towards 

 the outer margin " (0. Poseidon, Brit. Mus. Cat.) ; and by having 

 on the under-side the transverse macular band separated into 

 two parts. 



From the O. Archideus, (of which the female is only known) 

 it differs by " the white of the secondary wings " not " reaching 

 to the disco-cellular nervules and a portion of the median nervule," 

 nor " occupying a small space within the discoidal cell." 



And from the O. Victorise, (of which the female is only 

 known) it differs by the far greater obscurity of colouring of 

 the entire surface ; the whitish markings being in no ways propor- 

 tionate to those of the Victoria ; indeed rendering a further 

 comparison between them needless.
