IV. THE PAPTLTONTNA. 121 



5. CATOPSILIA CATILLA,* Cramer. 



The expansion of the wings is nearly 3 inches. On the upper side all the wings of 

 the male are pale sulphur-yellow, with a minute brown mark at the apex. The female is paler, 

 with a brown spot in the centre of the fore-wings, and a chain of brown spots on the termen 

 towards the apex. 



A single male specimen of this butterfly was captured in the grounds of St. 

 John's College, Auckland, and is now in the Auckland Museum. The species is very 

 common in Australia, and as this is the only specimen observed it was no doubt 

 accidentally introduced from that country on board a steamer.
