In the Staudinger coll., from German New Guinea 6 <? , 

 8 2 ; from Molne Bay, S. New Guinea, 2 3 s , 3 2 ; Pupa 

 from Laro and Obae. By most authors Pegasus is con- 

 sidered to be a form of Poseidon; and it is really impossible 

 to object to this arrangement. The type form of Felder 

 was probably discoloured, and so misled us all in esti- 

 mating its specific value. Many examples of the & have 

 since come that do not appear to differ from those of 

 Aruana or Poseidon. There is 1 6* in the Brit. Museum, 

 ex Godman et Salvin coll., resembling Felder's type ; but 

 the late Mr. Salvin told me he did not believe in it. 



O. POSEIDON 



(including its many synonyms). 



In the Tring Museum : from N. Guinea 52 <? , 46 2 ; 

 Waigeu 8 $ , 12 2; Salwatty, Mysol, Key Islands, Aru 

 Islands, 12 6* , 9 2 ; Islands of Torres Straits and Cape 

 York 7 6* , 6 2 ; Louisiade Archipelago and D'Entre- 

 casteaux Islands, many examples. 



Var. Brunneus, with the marks of the anterior wings 

 obliterated, except a point-like spot between the lower 



median nervules. A 2 is also in this collection, with 

 the anterior cell mark graduated into the $ quality of 

 green — a singularly abnormal aberration. In the Vienna 

 Museum 2 $ , 1 2 , New Guinea ; 1 2 , Banda Island. 

 In the Staudinger coll., 1 6* , 1 2 , Cape York; 5 6* , 4

 Island, a var. 2 $ , 2 2 ; Waigeu, v. Cronius, 1 $ ; 1 $ , 

 locality unknown. In the Brit. Museum, Duke of York 

 Island, 2 $ (very golden green hind wings on the under- 

 surface). New Britain 1 $ \ Duke of York Island 2 2 ; 

 Torres Straits 3 S (with yellow subcostal mark on the 

 hind wing), 2 2; (the lighter resembles a 2 Unnlliana). 

 The median veins of the $ anterior wings vary greatly in 

 the intensity and extent of the green scales which accen- 

 tuate them ; 1 pupa ; Darnley Island, Torres Straits, 1 3 , 



2 2 ; 1 desquamated 2 ; Cape York, 6 J 1 (in 2 examples 

 there are no green scales on the anterior wing median 

 vein. Cape York 1 Pupa ; Cape York, 2 2 , Australia, 

 1 2 ; Wokau (Aru Islands) 2 $ , 1 2 (the anterior cell 

 marks nearly fill its whole area) ; 1 Pupa, Aru (Wallace), 

 1 S labelled Oceanus, (fide Butler), 4 $ ; Aru Islands, 



3 2 , belong probably to Urvilliana, 1 2 is the normal 

 Aruana. 



A 2 Poseidon from the Arfak Mountains of N. Guinea 

 has the anterior wing cell mark very large and indented 

 towards the base ; in 5 2 examples the cell spots are all 

 more or less incised ; in 1 $ from the Duke of York 

 Island, the green subcostal band is narrow and regular in 

 width, and the submarginal green band is broad, and 

 only dimly divided by the veins, and reaches nearly to the 

 apex.
