[Read 7th November, 1895.1 ONE of the first genera which 1 ever otudieil, and the Erst which I monographed, was the geiius Charaxes, a paper ou which I published in 1865 in the ' Proceedings ot the Zoological Society,' in which I recorded sixty-eight species (two of which, however, were noted as doubtful and ere subsequently suppremed) : the present paper enumerates no fewer than one hundred and fifty- nine. I have followed Prof. Aurivillius in uuiting Palla to Cliaraxes : if kept separate, it would have to be broken up into several geucra, and Charaxes ithelf would in like inanuer have to be sub- divided ; tliis, indeed, has been done for the Iiidian species by Mr. Moore ; but apart from outline of wing 1have been unable to discover any constant structural characters ou which to base these genera. That wing-outline in Charaxes is not of generic im- portance seems clear, from the fact that (i.) in iuany of the species it differs to an extraordinary degree in the sezes ; (ii.) the most nearly related species (as, for instance, C.
