 I am led to give Jl. Willughhiella as the Willow 

 Bee, whose history and economy so attracted the 

 attention of the English Naturalists of the last 

 century, by the circumstance of its having been 

 most commonly taken in places abounding with 

 willow trees. I find it in Barham in some low 

 meadows which are surrounded with them ; it is 

 also frequently met with at Brentford, and other 

 places near the Thames 



I have not hitherto been successful enough to 

 meet with its nidus, so as to ascertain whether what 

 I have given as the sexes come from the same, 

 but they agree together in such particulars as the 

 sexes usually do, and are found in the same situa- 

 tions, and therefore I feel no great doubt con- 

 cerning their identity. Sir John Hill, in his trans- 

 lation of Swammerdam's Book of Nature, in a note, 

 says, that he has seen thousands of the nests of 

 these bees in Lincolnshire (?/) ; it is probable that 

 where they so abound, they must do considerable 

 pjury to the trees in question.
