This little bee was one of great rarity in collections sonae 

 years ago, when a locality was discovered for it at Hawley in 

 Hampshire. I observed it entering the dead branches of the 

 bramble, in the month of June ; in the autumn I procured some 

 of the sticks, and bred numbers of both sexes ; subsequently 

 it has been found in plenty near Bristol. Three or four spe- 

 cimens have been taken at Charlton in Kent, but it is very 

 local.
