with dark fuscous. Thorax purplish-fuscous mixed with white, 

 sometimes suffused with brassy-yellowish. Abdomen whitish- 

 ochreous. Legs dark fuscous ringed with whitish, hairs of pos- 

 terior tibiie whitish. Forewings pointed ; pinkish-fuscous, 

 sprinkled with dark fuscous, sometimes whitish-mixed or suffused 

 with golden-yellow; an ochreous-yellowish subcostal streak from 

 base to |, marked with a black dot near base; sometimes a broad 

 pale or white subcostal suffusion from base to apex, its lower 

 edge margined by an undefined streak of blackish scales; stig- 

 mata blackish, plical obliquely beyond first discal; when there is 

 a median blackish streak the discal stigmata form projections on 

 its upper edge : cilia whitish-ochreous, pinkish-tinged, irrorated 

 with dark fuscous. Hind wings light grey; cilia pale whitish- 

 ochreous. 



Sydney, Xew South Wales; Gisborne, Victoria; George's Bay 

 and Hobart, Tasmania; Adelaide and Port Lincoln, South Aus- 

 tralia ; Geraldton, Perth, and Albany, West Australia; from 

 October to March, twenty-seven specimens. This species varies 

 considerably in colouring, especially in the development of white 

 suffusion in costal half of wing, the extreme forms being very 

 different in appearance; I at first thought they might include 

 several species, but finding that all the forms occur together in 

 the same localities, I have become convinced that they are 

 identical.

Antennas |, in ^ simple, basal joint long, with pecten. Labial

A genus of a single species, probably indigenous to America, 

 but now introduced into many parts of the world with imported 

 grain. It is a development of Aristotelia. Imago with forewings
