anterior border toothed, centre of band light grey, the costal 

 space divided by portion of second band on median line, and 

 bounded by first band and by a third band, is sufi'used with light 

 fuscous ; a rich chocolate line extends from before apex of costa 

 in short waves to before anal angle ; a submarginal lighter line 

 is connected with a finer marginal line by short bars. Cilia, 

 light fuscous. Hindwings woolly white, with a few light 

 fuscous hairs on costal margin, and a pale fuscous suffused spot 

 near anal angle. The ^ is larger, is similarly marked, but 

 has a smudged appearance, as the ground colour is ashy 

 grey, and the marks, both the darker boundary lines and the 

 enclosed spaces are of a much less definite tint, and appear as if 

 smudged with ashy grey. One pair taken by Mr. Illidge, 

 Brisbane.
