PREFACE. 



The object of the present Catalogue has been to give 

 a complete list of the species of Ichneumonidse that have 

 been recorded as found in the British Islands, marking 

 with B. M. in the margin the species contained in the 

 British Museum. The cabinets, where the species, at 

 present desiderata to that collection, may be seen, are 

 indicated. 



The species are arranged according to the method, used 

 in Professor I. L. C. Gravenhorst's Ichneumonologia Europcea, 

 Vratislavise, 1829, 3 vols. 8vo., and those supposed to be 

 new are described by the author.
