The Australian Epilachninae are reviewed. Epilachna dawkinsi is described. New synonymies established are: E. pardalis (Boisduval, 1835) with Henosepilachna vigintioctopunctata (Fabricius, 1775); E. doryca (Boisduval, 1835) and E. philippinensis Dieke, 1947 with H . vigintisexpunctata (Boisduval, 1835); and E. terraereginae Blackburn, 1895 with H. suffusa (Crotch, 1874). Henosepilachna Li, 1961 is removed from synonymy with Epilachna Chevrolat, 1834. New combinations proposed are: H. vigintisexpunctata (Boisduval), H. cucurbitae (Richards, 1983). H. mjoebergi (Weise, 1923). H. urvillei (Montrouzier, 1861) and H. suffusa (Crotch), all transferred from Epilachna Chevrolat. E. undecimvariolata (Boisduval, 1835) recorded from Tasmania is shown to be a misidentification. A key to the two genera and 10 species known in Australia is provided. A lectotype is designated for Epilachna borealis (Fabricius, 1779, the genotype of Epilachna.' Present address: 31 Thornton Cres., Casuarina, N . T.
