(J. 13-17 iiiiii. (15). Up per side uniform bluisli, slightly 

 white on costa of hindwing, caudal spot only faintly visible. 

 Tail black, tipped with white. Cilia brown. 



Underside grey, with discal areas white, often entirely 

 blotting out discal and discocellular spots, spots and bands repre- 

 sented by two parallel white lines, marginal and submarginal 

 series well developed, caudal spot black, crowned with yellow, a 

 small black anal spot. Cilia brown. 



9. 12-16 mm. (15). Upper side black, with central areas 

 white, often suffused with pale silvery blue, base darker silvery 

 blue, caudal spot faint. Tail black, tipped with white. Cilia 

 brown. 



Underside greyish-brown, with discal and discocellular 

 bands entirely effaced by white, outer marginal waved line very 

 prominent. Cilia greyish-brown. 



This species is recognised by the white discal suffusion below, 

 so prominent in female; it has usually been known as ]\\ perusia, 

 but Druce has pointed out that Jf. dion is close to iV. pencsia, so 

 as it is an older name and the type came from Australia it must 

 be used. 



Log. — Richmond River to Cape York (g 13, 9 13).
