and extending towards the hind margin ; the latter spot divided by 

 vein 3 at about its anterior fourth. Hindwing inclining to dull 

 ochreous-yellow at the base, hind margin darker, with a broad 

 oblique ochreous-yellow discal band or fascia, which extends 

 posteriorly from vein 7 ; this band is of uniform width through- 

 out, clearly defined in front, and gradually effaced behind. Under- 

 side : — Much paler in colour than above. Forewing beyond the 

 anterior markings (which correspond with those of the upper side) 

 and on the inner margin silvery-grey, the apical portion mottled with 

 small irregular transverse brown lines ; the discoidal cell occupied 

 by a rather bright ochreous-yellow patch, which is somewhat 

 suffused on the costal margin. Hindwing silvery-grey, indistinctly 

 irrorated with purplish, and closely striated with brown ; with 

 indications of two indistinct lighter oblique bands extending from 

 the costal and hind margins respectively to the inner margin near 

 the base. Cilia ochreous-brown. Expanse 53-55 mm. 



Somerset, Cape York, N. Australia ; and Port Moresby, British 

 New Guinea. 



As stated before, this species of Libythea has been confused with 

 a species (L. myrrha, Godart), with which it has little in common, 

 ever since the first specimens from Cape York were recorded; but it 

 will be evident upon even the most cursory comparison of the Aus- 

 tralian form and L. myrrha that the species are abundantly distinct. 

 In the Australian insect the fore wings are comparatively broader, 

 with the hind margins less distinctly angulated below the apex, 

 and the disk ornamented with whitish markings. The charac- 

 teristic transverse streak in the cell of the forewing of L. myrrha 

 is replaced in our species by a single rounded spot, in which 

 respect it resembles the Indian L. rohini, Marshall,* described 

 from the Khasi Hills. The latter species, indeed, would appear 

 to be its nearest ally, although sufficiently distinguished by having 

 the markings on the hindwing white like those of the forewing, 

 and by the presence of additional spots near the costa of the 

 former.
