and there is an obscure leaden-metallic line near hindruargin ; 

 cilia white, outer half grey it rorated with blackish. Hindwings 

 very thinly scaled, grey ; cilia grey. 



This small species is of peculiar appearance, and very distinct 

 from any other, being characterised by its small size, very narrow 

 forewings, dark colouring, and the pure white transverse streak 

 posteriorly. 



Three specimens taken at rest on a fence near Sydney, in 

 October. In repose the apex of the forewings is obliquely bent 

 in round the abdomen, as though deformed ; a habit which is not

 that noticed in the case of Helictoplianes uberana.
