104 BEES OF GREAT BRITAIN. 



' British Entomology/ It is strange that no second specimen 

 should have been met with, as these insects are usually distri- 

 buted in different localities, although some are much less abun- 

 dant than others. A species very closely resembling it is de- 

 scribed in the ' Catalogue of Andrenidse/ published by the 

 Trustees of the British Museum ; it is from Albania, and varies 

 much in its colouring, whence its name, A. variabilis.

A. atra, cinereo-subpubescens ; thorace pallide villoso ; abdo- 

 mine utrinque strigis tribus albis ; scopa pallide argenteo-
