" The insects of this genus are well known by the name of leaf 

 cutters and carpenter bees : their interesting economy having attract- 

 ed the attention of many naturalists, so early as 1670 it was noticed 

 by Hay, Dr. Lister^ \Villughl\v, and .Sir Edward King. Linne in this 

 as in many other instances (supposing the economy of a genus to 

 be peculiar to one species only) has confounded several species under 

 the general title of Apis ccntunculuris, and dedioted it l^y the orange- 

 coloured hairs which cover the under side of the abdomen, a cha- 

 racter which it possesses along with a great number of species."
