C R I O C E R I S AUSTRALIS, Jacoby, P.Z.S. 1876, p. 807. This species, described by m e in 1876, is (as a comparison with the type in the British-Museum collection, of the existence of which I was previously not aware, has convinced me) the true C. nigripes of Fabricius. Lacordaire's description of that species (vol. i. p. 573), which I took as a guide, and which made me believe that the insect before me was a different species, is totally at variance with the insect of Fabricius ; and m y description is therefore the right one, although the name australis must stand as a synonym.
