ANDRENID.E. 251 



Abuudaut in August on the Surrey and Hampshire com- 

 mons. It frequents the common heath. It does not seem 

 however, to have a wide distribution, as the only other 

 recorded localities I have for it are : Barmouth ; Lundy ; 

 (Smith). Cannock Chase; [Morice). Norfolk; {Bridtjmau). 

 Hastings ; Lowestoft.
