posterior pair whitish. Forewings elongate triangular, costa very 

 slightly arched ; hindmargin obliquely rounded ; light fuscous- 

 ochreous-tinged ; a well-developed nearly straight denticulate 

 dark-fuscous line from beyond one-third of costa to midrlle of 

 inner margin ; a similar line, more oblique, from costa beyond 

 two-thirds to inner margin at two-thirds curved inwards on 

 lower half, a well-developed transverse discal spot midway 

 between these two lines, a blackish hindmarginal line, somewhat 

 interrupted by veins. Cilia dark-fuscous. Hindwings with 

 hindmargin rounded ; colour, lines, and cilia as in forewings. 



The present species could easily be mistaken ior rubraria, Dbld., 

 to which it bears a close superficial resemblance, but differs con- 

 siderably in position of lines and discal dot, and especially by the 

 shorter antennal ciliations. One specimen at Glen Osmond, 10th 

 October.

 white line ; a hindmarginal row of obscure white dots, veins
