extracting the species with furcate antennse, for which he has 

 retained Jurine's name Cryptus, leaving the remainder of the 

 group under Hylotoma, following Latreille ; and it is only to be 

 regretted that he did not give another name to the genus, and 

 thereby avoid the confusion which Jurine has introduced by 

 employing the name Cryptus here, when Pabricius had 3 years 

 before given that name to a genus of Ichneumonidce, wliich Jurine 

 was aware of, from his referring one of his divisions in that 

 family to Eabricius^s genus in a subsequent page ; and had not 

 Panzer published those IcJmeumonida under the name of Alomya, 

 by wliich they are now well known, it would still be necessary to 

 substitute a new name, in which we should only be doing justice 

 to Fabricius. 



The male of Cryptus pallipes (a figure of which has never 

 before appeared in any work) was first taken at Coombe Wood, 

 by Mr. J. King ; and was named and described by Dr. Leach, 

 and deposited in the British Museum. J. F. Stephens, Esq. 

 was afterwards so fortunate as to meet with both sexes of tliis 

 extremely rare species in June, at the same place : the other 

 species {Tenthredo furcata Vill., C. ViUersii Leach) has been 

 taken at Bristol in June ; it is figured by Panzer in his Fauna 

 Insectomm Germanica, fasc. 46. tab. 1. ; and by Coquebert in 

 his Ulustratlo Iconographica Insectorum, tab. 3. fig. 4. mas. I 

 have retained Villers's name, although it is objectionable, from its 

 being a generic rather than a specific one, and descriptive of the 

 male only ; because as the greater proportion of insects have been 

 named from one sex, we shall never have our nomenclature 

 settled, if it is to be disturbed upon such occasions. 



Triglochm maritimum (Sea Arrow-grass) is figured in the 

 plate.
