THE ENTOMOLOGIST. 5 



5. C. manfUbularis is distingnished from all the other 

 species by its prominent genicnlated mandibles, the basal 

 half being thiclilj covered with pubescence; the wings have 

 a distinct fuscous border on the apical margins, not extend- 

 ing to the enclosed cells. The form of the apical segment is 

 very similar to that of C. simplex : a series of examples is 

 required in order to ascertain in what particulars it further 

 differs from C. simplex. 



6. C.Vectis is the largest known British species; its snow- 

 white widely inierrupted marginal bands on the abdomen, in 

 connexion with ihe form of the apical ventral segment of the 

 abdomen of the female, readily distinguish it from the same 

 sex of the other species ; the colour of the abdomen, so 

 intensely black, its coarse punctuation, and the lateral snow- 

 while fringe on the margins of the abdominal segments, at 

 once distinguish it : these patches of fringe are narrowed to 

 a point inwardly.

 Coelioxys 4-dentata, Smith, Zool. iii. 1151 ; Schenck, Bees 



of Nassau, 364, male, female. 

 Coelioxys acuta, Nyland. Man. Apum Boreal. 250, fe- 

 male. 

 'J'his species is not found in the London district, at least I 

 never knew of its occurrence ; I have taken it at Deal, and 

 in Suffolk, at Lowestoft ; Mr. Rothney found it near Ipswich. 

 I do not know what bee it is parasitic upon. 1 have rejected 

 all the synonyms which I could not confirm by an examina- 

 tion of specimens. The Fabrician and Kirbyan insects both 

 belong to the next species.
