with rosy outer margin ; the primaries with silver-centred rosy discocelkilar 

 Si^ot, and three or four obUquely-placed strioles between tlie median and 

 discoidal branches ; secondaries with two connected silver- centred rosy spots 

 at the end of the cell, and six to seven discal lunules forming an arc round 

 them; expanse of wings, 3 inches 1 line. 



Female. — Above typically bright sulphur-yellow, sometimes (and gene- 

 rally in the Australian region) pale sulphur-yellow, almost white ; the 

 primaries with a broad dentated, sometimes interrupted, marginal border ; 

 a more or less defined waved striolate discal band and discocellular spot, 

 all blackish ; secondaries usually with orange-tinted external border, the 

 veins terminating in blackish dots ; below golden-yellow, the outer border 

 slightly deeper coloured, a rusty irregular patch (sometimes obsolete) 

 terminating the cells of both wings and enclosing two connected silver- 

 centred ocelloid spots ; primaries with a rust-reddish discal interrupted 

 angulated band ; secondaries with three black-centred orange lunules on

The wings are black, becoming brown towards the base ; the primaries 

 have three sordid whitish spots, and the secondaries have the whole central 

 area of the wings white. 



We have never seen an example of this species from New Zealand, but 

 in Dieffenbach it is noted as belonging to the Lepidopterous fauna : as the 

 species seems to frequent gloomy brushwood, it may have been overlooked 

 by recent explorers.
