194 Mr. R. H. F. Rippon on a 



largest, and each of them being rather a congeries of more 

 or less densely sprinkled atoms than a continuous patch of 

 green ; the first four of these, starting from the posterior 

 portion of the wing, are divided nearest to the outer margin 

 lay a more or less sublunate black spot ; the fifth contains a 

 triangulate, indented, and the sixth an elongate mark ; all 

 the green patches are well separated from the neuration by 

 black and from the exterior margin of the wing by tawny 

 black. 



Secondaries : a silky green-blue extending over the wing 

 till just within the second subcostal nervure, when the 

 colour abruptly becomes a rich green, somewhat like that of 

 0. aruana (Felder) ; this fills the remaining space of wing- 

 to the anterior margin, but is not found within the discoidal 

 cell ; the green and green-blue are delicately dusted and 

 gradated by black atoms outwards from the base and down- 

 wards ; three black submarginal ovoid spots, the first within 

 the first and second subcostal nervules twice the length of 

 the third and less distinct, being dusted with green atoms; 

 the outer margin of the wing narrowly black, the median and 

 subcostal nervure and first subcostal brancli black and well- 

 defined in the green ; the space within the precostal nervure 

 to the base brown -black. Underside ricli golden-green, as in 

 aruana ; the space from the anal angle within the submedian 

 nervure and third median nervule halfway up golden-yellow, 

 base black ; six large submarginal black spots, the upper one 

 quadrate, the others more or less suboval ; anterior margin 

 partly filled with green, and space on each side of pre- 

 costal nervure with green atoms ; exterior black margin 

 slightly broader than on the upperside, indented inwardly 

 within the first and second subcostal and second subcostal 

 and discoidal brandies ; the subcostal nervure and its first 

 branch well defined by black. 



Head. — Eyes pearly light brown, margined with white \ 

 space between deep black; antennai light smoky brown. 



Thorax. — Velvety black, with a very obtrusive longitu- 

 dinal green-blue stripe ; beneath lateral red patches and tawny 

 black. Legs black. 



Abdometi. — Golden yellow and ferruginous brown, the 

 latter perhaps intensified by fading ; anal segment with the 

 usual trisinuate black mark and a minute tawny curved spot 

 on each valve divested of scales ; lateral black dots six in 

 number. 



Length of costa 80 millim. ; antennaj and abdomen each 

 33 millim. ; head and thorax about 20 or 22 millim. 



Hab. Aru Islands.
