796 REVISION OF AUSTRALIAN LEPIDOPTERA, 



margin, concave ; its posterior edge running from § of costa to ^ 

 of inner margin, rather sharply angulated near costa, thence 

 slightly sinuate, marked with a row of black dots, and generally 

 followed by a well-marked pale or whitish double line ; a some- 

 what darker suft'used spot towards hindmax'gin above middle ; an 

 interrupted blackish hindmarginal line : cilia ochreous-whitish, 

 somewhat mixed with reddish-ochreous and spotted obscurely with 

 grey towards base. Hindwings with hindmargin dentate, rather 

 deeply concave above middle ; ochreous-whitish, with numerous 

 straight fuscous-i-eddish transverse lines, somewhat bent near 

 costa, sometimes marked with black on veins ; posterior edge of 

 median band obtusely angulated near costa, marked in ^ with a 

 thick black streak, in ^ with a i-ow of black dots, followed l)y a 

 more distinct pale double line ; cilia light reddish-ochreous, tips 

 more whitish. 



Sydney and Mount Kosciusko (5700 feet). New South Wales ; 

 Melbourne, Victoria ; Hobart and Deloraine, Tasmania ; from 

 October to January, common. 



4. Phrissogonus, But!. 



Face with small cone of scales or quite smooth. Antennae in ^ 

 ciliated or naked. Palpi moderate or short, porrected, more or 

 less rough-scaled. Abdomen slightly crested. Posterior tibiae 

 with all spurs present. Forewings in ^ with swelling or tuft or 

 rough projecting scales on costa, vein 5 sometimes distorted or 

 absent; areole simple, 11 running into 12. Hindwings with 

 veins 6 and 7 stalked. 



Confined to Australia, except that one species ranges into New 

 Zealand. In the following tabulation the species are separated by 

 characters common to both sexes, although the J" and 9 are often 

 very dissimilar in appearance ; but the structural variations in the 

 forewings of the ^, which are difl^'erent for each species, affoid 

 an easier test.
