PRACTICAL BEEKEEPING 7 
antennae are appendages of the head believed to bear sense organs. 
Cleaning the antennae is accomplished by the bee’s throwing the fore 
leg up over the head, and the antennae fitting in the indentation, is 
inclosed by the spur and drawn through the circular comb thus 
formed. By this process, repeated several times, all particles of 
dust are removed from the antennae by the little teeth of the 
comb. The tibial spur of the middle leg is used as a crow-bar in 
the removal of the pellet of pollen from the tibia of the hind leg. 
In the hind leg the spur is missing, but located in a similar position 
to that of the antennae cleaner we have a structure known as the 
wax-forceps which is opened and closed by the bending of the 
tarsal joint on the tibia. The use of this forceps will be spoken 
cf later in connection with the wax glands.

The tibia of the hind leg is modified to form a pollen basket 
known as the corbicula. This basket is formed simply by long 
curved hairs arranged along the edges of the flattened and indent- 
ed tibia, curving outward and over, enclosing, when filled, the pel- 
let of more or less adhesive pollen.
