Sp. 3. Vespa rufa, Linn, and Fab.

The Female is 8–9 lines in length. Head black; clypeus yellow, a black line down the centre, with an anchor-shaped termination, sometimes the line is abbreviated, forming a simple dot; mandibles yellow, teeth dark ferruginous; a crown-shaped spot at the base of the antennæ, a line at the inner margin,
