Completes the revision of the oecophorine genera of Australia and includes the large Barea group of genera, the small Tisobarica group, some genera previously omitted in the first two volumes from the Wingia and Chezala groups, and some miscellaneous genera of unknown relationship. This volume deals with 96 genera, 73 of which are referred to the Barea group, two to the Tisobarica group, four to the Wingia and Chezala groups, and 17 to the group of unplaced genera. As in the first two volumes, nearly all of the genera are endemic.
