This is the most abundant species of the genus found in En- 

 gland, and appears to be generally distributed. It occurs in all 

 parts of the country. The popular name of the Willow Bee is 

 certainly very appropriate. Some years ago, when decaying ( 



willows were numerous in the Battersea Fields^ the old stumps 

 were perforated with innumerable burrows formed by this species. 

 Mr. Kirby also quotes a passage from a note by Sir John Hill, 

 in his translation of Swammerdam, where he says he has seen 

 thousands of the nests of this bee in Lincolnshire, in the old 

 willow-trees.
