606 REVISION OF AUSTRALIAN LEPIDOPTERA, 



hindmargin rounded, somewhat uneven ; whitish ; inner margin 

 narrowly suffused with blackish ; median shade very faint, 

 cloudy, grey ; a grey discal dot ; second line slender, grey, very 

 indistinct ; a cloudy fuscous-grey irregular subterminal shade ; 

 an interrupted fuscous hindmarginal line. 



Albany, West Australia ; in October, one specimen amongst 

 Leytospermum in a swamp. Easily separated from the preceding 

 by the general black suffusion obliterating most of the markings 

 of the forewings, and the clear white posterior patch ; the 

 neuration is also different, but would perhaps not be constant.

(Boarmia cognata, Walk. 392.) 



(J^. 24-27 mm. Face blackish, forehead grey-whitish. Antennal 

 pectinations of <J 8, of 9 6, apical -I- simple. Forewings with 

 hindmargin obliquely bowed ; 10 sometimes connected with 12 

 and 9, 1 1 absent ; pale ochreous-grey, densely irrorated with 

 whitish ; first and second lines and median shade fine, fuscous-

 followed by a fuscous-grey parallel more cloudy line ; a dark grey 

 discal dot before median shade ; subterminal obscurely whitish, 

 slender, dentate, margined with fuscous-grey ; a hindmarginal 

 series of black dots. Hindwings with hindmargin somewhat

Sydney, New South Wales ; Melbourne, Victoria ; Deloraine 

 and Hobart, Tasmania ; Mount Lofty, South Australia \ from 

 September to January, common. Characterised by its small 

 size, light colour and general whitish irroration, dotted lines, and 

 especially by the unusually strongly pectinated antennae of the 

 Q, which are little inferior to those of the <J in development.
