DESCRIPTION OF THE FIRST WINGED SPECIES OF PSEUDOBARGYLIA (, REDUV1IDAE, ) By Pedro Wygodzinsky The American Museum of Natural History Abstract

The paper contains the description of the first winged species of the emesine Pseudobargylia, which had been known only from apterous specimens. 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.
