Variable, with tendency to localisation of colour- varieties; 

 forewings sometimes partially tinged or wholly suffused with 

 ferruginous ochreous; this suffusion begins towards dorsum and 

 spreads more or less over whole wing; sometimes in ^ the veins 

 are indicated by lines of blackish specks. From Bathurst and 

 All)any I have seen only the form with ferruginous-ochreous 

 suffusion; at Gisborne and in Tasmania the grey and ochreous 

 forms occur together, with intermediate varieties.
