Show 402 Ltf.-COL. C. T. BINGHAM ON THE [Mar. 17, the island. Three hundred and forty-one species, of which have not previously been described, are here recorded, a number, however, far less than what must actually occur in an island with so varied a climate and flora as Ceylon. The species, as was to be expected, are chiefly Indian, but I have thought it premature to enter into any detailed comparison of the fauna with that of any other portion of the Oriental region, more especially as, since the pubhcation, nearly thirty years ago, by the late Mr. Smith of his ' Catalogue of the Aculeate Hymenoptera and Ichneumonidce of India and the Eastern Archipelago,' no comprehensive list of the hymenopterous insects of India has appeared. I have to add, by way of explanation, that, in the following list, where no locality is mentioned the insect does not occur in either Colonel Terbury's or Mr. Green's collections, and has simply been recorded or described from Ceylon, with no particular locality indicated.
