426 DESCRIPTIONS OF AUSTRALIAN MICRO-LFPIDOPTERA, 



posteriorly dilated, rather pale ochreous, irregularly mixed with, 

 numerous black scales, which tend to form irregular margins to 

 the metallic markings, between which they also form black spots 

 on costa ; they also generally accumulate in an irregular black 

 patch on anal angle ; seven oblique transverse somewhat irregular 

 leaden-metallic lines from costa to inner margin, indistinct towards 

 base, the three apical lines clearest and becoming whitish on 

 costa ; between each pair as far as the sixth is an obscure leaden- 

 metallic costal spot, only the last being distinct ; between the 

 sixth and seventh is a small round leaden-metallic spot on disc 

 above middle ; seventh line ending on hindmargin about middle ; 

 a short curved transverse leaden-metallic line immediately before 

 apex : cilia pale ochreous at apex, becoming fuscous-grey towards 

 anal angle, with a broad leaden-metallic basal line. Hindwings 

 dark fuscous-grey ; cilia grey, with a blackish line near base. 



? . Eorewings elongate, narrower than in male, not dilated, 

 more suffused, the leaden-metallic markings tending to coalesce 

 in pairs, so as to leave an oblique dark basal patch, central fascia, 

 and costal spot before apex produced to anal angle. 



This species may be at once distinguished from I. ranulana by 

 the leaden-metallic markings, and generally darker colouring ; 

 the male especially is also broader-winged. 



Taken rather plentifully near Blackheath 011 the Blue 

 Mountains, New South Wales, at a height of 3,600 feet, in 

 October ; the male flying wildly in the hot sunshine round the 

 tops of tall Eucalyptus bushes, the female keeping nearer the 

 ground. I have also a male of this species taken near Sydney 

 nearly on the sea level, which differs only in being more suffused 

 with smoky-fuscous, with the metallic markings broader and 

 more obscure.
