440 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



joint shortly triangular- sealed, terminal joint distinct. Forewings 

 triangular, posteriorly much dilated, costa in male with broad 

 basal fold, hardly arched, not bent, apex rather produced, hind- 

 margin sinuate. Hindwings rounded-trapezoidal, broader than 

 forewings. Forewings with veins 7 and 8 stalked, 7 running to 

 hinclmargin. Hindwings with veins 3 and 4 separate at origin 

 but very near together, 5 closely approximated to 4 at base, 6 

 and 7 stalked. 



Nearly allied to Acropolitia, but veins 6 and 7 of hindwings 

 are always stalked, the costa of forewings is hardly bent in the 

 male, the apex is always more or less produced and the hind- 

 margin sinuate beneath it, whilst in Acropolitis the apex is 

 rectangular. 



The species are rather brightly coloured with ochreous or 

 ferruginous tints.
