Eeadily distinguishable from the otlier Australian species by 

 the brown clouding of the apex of the wings ; in the anterior 

 winga this clouding is confined to the poststigmatical costal 

 space, but in the posterior it invades almost the entire apex. 

 The anterior wings are comparatively shorter and broader than 

 in the allied species. 1 liavc an individual from the same lo- 

 cality as Brauer' 8.
