Secondaries resemble those of Paradisea except that the 

 discal area of grey white is i-4th larger, and encroaches 

 a little way within the discoidal cell, the outline of its 

 upper part being very irregular in curvature and excision, 

 — the narrow portion between the ist and 2nd submedian 

 branches suggesting an inverted cornucopoea, — -the short 

 discoidal nervules are very black and distinct, all the 

 other veins running through the black only faintly visible, 

 except towards the posterior margin ; in the grey area are 

 5 suborbicular black spots, all of them large, but the ist 

 and 5th are ovoid and larger than the other 3 ; just above 

 these the grey begins to be dusted with dark scales, and 

 below them densely with black scales and atoms on a 

 brown-ochreous ground, rather yellower on the cornu- 

 copceoid division ; there are 2 small yellowish subapical 

 spots, the lowest nearly united with the cornucopoeid 

 mark, the other close to the costa above it. The under- 

 surface almost entirely the same as above, except that 

 the light discal area has no dark dustings, or only at the 

 edges of the black marginal band, and below the sub- 

 orbicular black spots the spaces are pale chrome yellow ; 

 there is an irregular-shaped spot of yellow atoms at the 

 apical angle ; all the veins are prominently seen on the 

 black, which is not the case on the upper surface ; the 

 precostal cell is yellow (in Paradisea it is white). The 

 white marginal fringe lunules very obscure. 



Head, antennae and thorax black ; eyes dark castaneous. 

 Thorax with large pectoral red spots except near ist 

 pair of legs ; dorsum of abdomen grey, and subdorsum 

 yellow ; the dorsum with lateral rows of minute black 

 twin dots, subdorsum with the usual lateral row of black 

 dots ; the articulations well expressed by black, the 

 penultimate segment orange yellow, as is also the anal 

 fringe. 



Head, with thorax, 10 mms. ; antennae or abdomen, 32 

 mms. ; costa, 93 mms. ; posterior margin, 61 mms. ; in- 



terior margin, 39 mms. ; width of wing, 52 mms. ; width 

 of secondaries, 40, and length 63 mms.

The femora appear not to be white as in Paradisea. 

 The form of the protarsus and short length of the other 

 4 tarsi are exactly as in the 2 of Paradisea. 



Hab. : Waigeu or Waigiou. 



I am indebted to the liberality of Mr. H. Grose-Smith 

 for the loan of the two examples of this superb species 

 from which my figures are drawn. 



The neuration of the 2 of this species is somewhat like 

 that of O. Priamus and some of its allies, but in both 

 sexes the position and starting points of each subcostal 

 nervule differs a little from those of Priamus, and also 

 from those of Paradisea, though I have no doubt of its 

 congeneric relation to the latter. 



I would suggest that the absence of the stigmatic brand 

 in this genus is in some way compensated for by the 

 presence of the abnormally long abdominal fringe in the 

 $ . I could give reasons for this, if it were necessary, but 

 reserve them for the present. 



The Hon. W. Rothschild points out in his Novitates 

 Zoologies, vol. II., p. 196, that in the 2 " the number and 

 size of the white spots of the fine wings are inconstant ; 

 the markings on the disc behind the cell are especially 

 liable to obliteration. The white, internervular, marginal 

 fringe is often much reduced."
