362 A Neiv Papilio from Burn 



The similarly opalescent magellanus is apparently nearer to aeacus 

 than is rhadamanthus, and it seems that our new form is derived from 

 some progenitor of magellanus and aeacus. 



The opalescence of the new species is found on both sides of the 

 hind wing, whilst in magellanus it is seen only on the upper surface. 

 In prattorum there is a strong fluorescent greenish appearance with 

 transient purple flashes in certain lights. In magellanus the opales- 

 cence is mostly purple and is less strongly marked.
