802 REVISION OF AUSTRALIAN LEPIDOPTERA, 



Hindwings in ^ with distorted impression or flocculent discal 

 patch ; veins 6 and 7 stalked. 



Probably confined to Australia. The (Js are very easily distin. 

 guished by the peculiar characters of the hindwings, but the ^s 

 of the diflTerent species ai'e extremely like one another ; I am not 

 sure whether the subjoined tabulation is always applicable. 



1, Forewings with thick black basal streak 10. melanocausta. 



Forewings without black streak 2. 



2. Groundcolour grey, posterior edge of median 



band distinctly projecting above and 



below middle 11. squamulata. 



Groundcolour grey-whitish, posterior edge of 



median band nearly straight 9. villosata. 



9. Micr. villosata, Gn. 



(Microdes villosata, Gn. X, 297, pi. xv, 8 ; Panagra inixtaria, 

 Walk. 1663; Microdes toriata, Feld. pi. cxxxi, 34. 



(J^. 19-20 mm. Head, palpi, thorax, and abdomen whitish 

 irrorated with grey. Antennae whitish, in ^ naked. Legs 

 dark grey, posterior pair whitish. Forewings triangular, costa 

 rather strongly arched near base, hindmargin slightly bowed, little 

 oblique ; veins in ^ somewhat distorted, with a naked space beneath 

 between veins 6 and 7 at base ; grey- whitish, irrorated with rather 

 dark grey, forming numerous waved nearly straight transverse 

 lines, on anterior § somewhat bent near costa, partially marked 

 with blackish on veins : cilia grey-whitish, with a basal row of 

 grey spots. Hindwings in ^ small, narrow, with a large circular 

 impression towards hindmargin in middle, surrounded with 

 irregular rough hairs, hindmargin strongly emarginate in middle,
