broad bidentate projection ; a blackish hindmarginal line : cilia 

 light fuscous, basal half dark grey except base. Hindwings with 

 hindmargin waved, rounded ; ochreous-orange ; dorsal half irrorated 

 with fuscous, and marked with transverse darker fuscous lines ; a 

 rather dark fuscous suffused band along hindmargin, becoming 

 attenuated towards apex ; cilia as in forewings, becoming light 

 yellowish round apex. 



Mount Lofty, South Australia ; one specimen received from 

 Mr. E. L. Guest. It is extremely similar to //. languescens, but
