" 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 Ray, Dr. Lister, Willughby, 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 vmdcr 

 the general title of jlpis centuncularis, and deiioted it by 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."
