this female and the series of the same sex from Guadalcauar is that 

 the submarginal spots are very small. 



Mr. Woodford informs me that both Ornithoptera victoricB and 

 O. urvilliana are very fond of frequenting the sweet-smelling white 

 flowers of Cerbera odollam^, a plant common in the SolomoQ Islands, 

 and also in the Fiji islands.

' Cerbera odollam, Mr. Hemsley tells me, is closely allied to the Oleander, 

 and similar in aspect. It is common on the sea-shores of India, Ceylon, Malaya, 

 North Australia, and throughout Polynesia, even as far eastwards as Pitcairn 

 Island, though it does not reach the American coast. The seeds will bear long 

 immersion in the sea without injury, and the plant is one of the early inhabi- 

 tants of coral islands. 



* Exhibited for the first time.
