with dark fuscoxxs, limited by hardly waved white lines, anterior 

 from beyond J of costa to | of inner margin, almost straight, 

 posterior from before | of costa to f of inner margin, slightly 

 waved, median third forming a strong acute equilateral triangular 

 projection ; sometimes a second similar whitish line immediately 

 beyond this ; sub terminal slender, waved, white in middle and 

 towards costa, elsewhere obscure, preceded by a blackish suffusion, 

 which forms a blotch above middle extending to hind margin, 

 margined above by an indistinct oblique whitish apical streak ; 

 all white markings sometimes i)artially suffused with grey ; a 

 blackish hindmarginal line : cilia fuscous barred with dai'k fuscous, 

 base and a median line sprinkled with white. Hindwings with 

 hindmargin strongly waved, rounded ; light fulvous-ochreous, in 

 ^ more yellowish in disc, irrorated with fuscous, with obscure 

 waved fuscous transverse lines, darker and more distinct on poste- 

 rior half, towards hindmargin forming a more or less suffused 

 band ; on inner margin these are darker fuscous, and separated by 

 white scales ; a blackish hindmarginal line ; cilia white, with a 

 gi'ey median line and indistinct grey bars, terminal half distinctly 

 rosy-tinged. 



Bathurst (2700 feet). New South Wales; Melbourne, Victoria; 

 Mount Lofty, South Australia ; in February, four specimens. One

 of the basal portion of vein 10, viz., that which extends from its 

 origin to its anastomosis with 11, and is to be regarded as a 

 diseased modification only.
