Pseudobargylia alata, as to new species, was collected in Ballarat, Victoria. The generic definition is completed so include characters of taxonomic importance for the winged morph of emesincs: the pro- large discal cell notum is abbreviated, as in the apterous morph, and the forewings have a and a small subtriangular basal cell. stripe The finding of a winged specimen of Pseudo- stramineous, with narrow reddish brown stramineous above, bargylia, described in this paper, is of unusual along middle.
