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

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

 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.
