roses and violets, from which they extract the honey contained 

 in the nectaries, whilst on the wing : they also frequent woods 

 and plantations, where the sun has access, before the trees are 

 clothed with their summer verdure. 



As the species are not numerous I shall give the characters 

 of those which have been recorded as British. I appear to 

 have two that are undescribed, one of which I supposed was 

 the B. 7iitidulus Fab., but I am now convinced it is not, and 

 Nos. 3, 4, and 8 are admitted on the authority of the Syste- 

 matic Catalogue.
