238 BEES OF GREAT BRITAIN. 



tion of this species, in consequence of Kirby using the terras 

 " abdomen subtriangular " and " anus albus ; " the latter is ful- 

 vous, which in worn examples becomes white. I have used the 

 term subglobose in describing the abdomen of the male, and al- 

 though strictly it is subtriangular, still, in contradistinction to 

 the male of A. campestris, it is subglobose, and will serve as a 

 distinction between them. 



This bee occurs in great profusion in Yorkshire ; it also occurs 

 in Scotland, and is not rare in the London district.
