« 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, Wil'lughby, and Sir Edward King. Linue in tins 
as in many other instances (supposing the economy ol a genus to 
be peculiar to one species only) has confounded several species under 
the general title of Apis centuncularis, and denoted 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.”
