NEW BRITISH SPECIES, NOMENCLATURE, ETC. 123 



Cryphis, Phygadeuon and Hemiteles are extremely ill- 

 defined. Male insects, whose females are unknown, may 

 often be referred to Cryptus or Phygadeuon indifferently. 

 And Hemiteles is a receptacle for all species, however 

 otherwise dissimilar, which have an imperfect areolet, a 

 character j^revailing extensively also in Phygadeuon. I 

 have seen some MSS. genera of Forster intended to re- 

 medy these defects, but they were unfortunately names 

 only, without characters, which could only be conjectured 

 from the types assigned to each. The Ophionides, Try- 

 phonides and Pimplides, thanks to the Swedish monographs, 

 are much better elucidated. If some of the genera, as 

 notably among the Tryphonides, rest upon very minute 

 characters, it is because this is inevitable throughout the 

 Ichneumonidm. Unobserved British species, described by 

 Holmgren, turn up at every fresh examination ; and indeed 

 there seems no reason why any members of the Scandinavian 

 Fauna should be strangers to Great Britain, or at least to 

 the Highlands, which are the exact counterpart, if they are 

 not a continuation, of the Norrska Fiellen. 



Mr. Scott has kindly lent me a box containing nearly 300 

 parasites (^IchneumonidcB, BraconidcB, and Chalcididce), with 

 a list of the Lepidoptera, &c. from which they were bred. 

 Many small species are indeterminable from age or other 

 causes, and of them and the Chalcididce I can give no 

 account. But of the rest I shall here give a list, with 

 additions furnished by other correspondents, including a 

 number bred by Mr. D'Orville of Alphington, Mr. Fletcher 

 of Worcester, the Rev. J. Hellins of Exeter, and others.
