joints are called digiti,, or fingers, or collectively the 
tarsus. 
Fig. 15 . — Hind Leg of Worker, Queen, and Drone. 
At the extremity of the terminal joint (/) are the two 
claws (Fig. 17, m ni), very hard and strong. They are 
hook-shaped, and have a smaller booklet within. 
These claws (anguiculi) enable the bees to suspend 
themselves and to hang on, the one to the other, as 
in comb -building, when placed in an empty hive. 
They have both lateral and perpendicular movements, 
and between their insertion is affixed the pulvillus, or 
cushion (Fig. 17, n).
