[z=citrina^ Feld.), from Aru ; but it would need a good series 

 of both to ascertain their comparative differences with pre- 

 cision. Koch's type was from the island of New Georgia, 

 and there is a specimen of the female in the Britisli Museum 

 from Kei Island which hardly differs from Mr. Thomson's 

 except in being a little yellower at the base. It is this which 

 Mr. Butler formerly described as a variety of his Danais 

 gloriola, Felder appears to have confounded the two, as he 

 states that it occurs both in Kei and Aru, though his descrip- 

 tion and figures correspond with Butler's gloriola from the 

 latter locality.
