the island. Three hundred and forty-one species, of which seven 

 Jiave 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 publication, nearly thirty years ago, 

 by the late Mr. Smith of his ' Catalogue of the Aculeate Hymeno- 

 ptera 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.
