the wing. Hindwing brown, with the pattern of the markings as 

 in the previous species, but much darker, with a ver}^ dark central 

 blotch and a dark blotch towards outer margin. 



This no doubt is what Miskin determined to be 0. orcetes (9), as 

 it was the only specimen at all like that sex that was in the 

 Australian Museum when he saw the specimens. He says it 

 agrees "pretty well" with Hewitson's figure of 0. orcetes (9). It 

 is a much darker blue than any except its female, and the black 

 outer margin is much broader than in either of the males of the 

 other species, being as broad as the outer margins of the females 

 of 0. onetes and 0. heivitsoni. 



9. Upperside. Foretoing dark silvery-blue, costal margin 

 black, narrow until the end of cell, where it broadens out to the 

 width of the cell ; apex broadly black, and outer margin very 

 broadly black; two white splashes on costa near apex, the blue and 

 black occupying about equal areas. Hindwing dark blue, with a 

 broad black outer margin and a black line at end of cell. 



Underside, Foreioing darker than in male, but otherwise 

 as in male, except that the areas of the cell between the first and 

 second, and third and fourth white bars are brilliant scarlet and 

 the white bars are more sprinkled with blue scales. Hindiving 

 as in male, but much darker. 



Hewitson's figure of the female of this species is excellent, and 

 there can be no mistaking it. Miskin is also correct in his iden- 

 tification. In the possession of scarlet in the cell of the underside 

 it resembles the female of 0. hewitsoni; but then the uppersides 

 of the two species are totally different. The recognition marks 

 of this species are the broad black outer margins on the upperside; 

 and on the underside the black discal band starts from near the 

 costa, proceeds a short distance, and then is lost in the black 

 lower half of the forewing. 



This appears to be a rare species; Hewitson has recorded it 

 from Moreton Bay, and I have taken it on the Richmond River.
