(Gray), which is common in Queensland and New South 

 Wales. 



From the green species (in some of which the green sub- 

 costal band is shot with coppery-red in certain lights) we pass 

 on to T. urvillianus (Boisduval), in which the green is replaced 

 by rich deep blue, showing a green or coppery iridescence on 

 the band in certain lights. It has lately been found in New 

 Guinea, New Ireland, Duke of York Island, and the Solomon 

 Islands. The larva, which feeds on Arisfolochia, the favourite 



Troides Hchwondia, <$. 



food of so many tropical and sub-tropical Butterflies, is black, 

 with carmine tentacles, and fleshy spines, the latter tipped with 

 black. 



Another remarkable species is T. crotsus (Wallace), from the 

 island of Batchian, one of the Northern Moluccas. Here the 

 green or blue of the species we have already mentioned is 

 replaced by a brilliant golden orange, shading into green in 

 certain lights. Mr. Rippon proposes the name Priamoptera
