white, tarsi and tibiae banded with blackish. Porewings rather elongate- 

 triangular, costa slightly arched, apex rounded, hindmargin obliquely 

 rounded ; white, densely irrorated with black, sometimes partially suffused 

 with light fuscous ; several small black spots towards base ; first line well- 

 defined, somewhat curved, sharply indented, posteriorly strongly black- 

 margined ; orbicular moderate, circular, black, whitish-centred, almost 

 touching first line ; claviform quadrate, black, detached ; reniform indis- 

 tinct, irregularly 8-shaped, lower half elongate, whitish, partially black- 

 margined, posteriorly strongly, touching a small blackish spot on costa 

 beyond middle ; second line well-defined, anteriorly black -margined ; 

 terminal space wholly dark, except rather broad distinct subterminal line, 

 entire or shortly interrupted, not touching second line : cilia white, sharply 

 barred with dark grey, bars partially obsolete on terminal half. Hindwings 

 1J, whitish-grey, becoming fuscous-grey posteriorly, postmedian line faintly 

 darker ; cilia white, with a well-defined grey line. 



This and the following species are characterized by the intensity of the ir- 

 roration and markings, and especially by the subquadrate detached claviform. 



Sydney, New South Wales, in September; Mount Wellington (1,000 

 feet), Tasmania, from December to February ; four specimens.
