210 DESCRIPTIONS OF ATJSTEALIAN MICRO-LEPIDOPTERA, 



mner-margin, interrupted on fold; an outwardly curved metallic 

 blue-purple line from f of costa to anal angle, lower half 

 interrupted to form three spots near and parallel to hind- 

 margin ; lower f of space between this and central line strewn 

 with ochreous-whitish scales, especially towards inner-margin ; 

 beyond this line is a white outwardly oblique spot on costa, 

 emitting a faint band of transverse whitish strigiilse along hind- 

 margin to anal angle, leaving three elongate black spots on 

 lower part of hind-margin ; bej^ond this band is an outwardly 

 oblique orange-ochreous subapical spot from costa ; cilia at 

 extreme apex black, beneath apex with an oblong transverse 

 snow-white spot, thence metallic blue-purple. Hind- wings deep 

 yellow, with a broad black margin ; cilia yellow, with a black 

 basal line. 



This richly adorned insect cannot be confused with any other. 

 Its habits are truly sun-loving ; it sports in the hottest sun-shine 

 over the tops of young trees of Acacia decurrens, to which it appears 

 certainly attached. Taken occasionally in New South Wales at 

 Parramatta, and at Waratah on the lower Hunter ; also at 

 Melbourne and Brisbane, from January to March.
