sinuate above and below, more strongly below ; space between second

 narrow line near and parallel to third, on projection sutiused with

 anal angle, edged posteriorly throughout with whitish, a suffused 

 whitish apical dash ; a waved black hindmarginal line ; cilia 

 fuscous, barred with whitish-fuscous, basal-half dark fusxious, 

 base sprinkled with white. Hindwings with hindmargin waved, 

 rounded ; slaty fuscous : three short, whitish, dark margined 

 streaks on inner margin above anal angle, upper one continued

Very near D. triparafM, Walk., l)ut a stouter built insect, 

 broader winged, hindmargin more bowed, etc. The descriptions 

 of this species and " triparata " read somewhat alike, but the 

 difference in the insects when compared is well marked. Black- 

 wood and Highbury, S.A., not uncommon in November. Mr. 

 Meyrick has specimens from the "Grampians," Victoria.
