200 Morphology of the Legs of Hymenopterous Insects. 
these beautiful brushes will always be found with more or less pol- 
Jen adhering to them. Of course the combs of one leg are used to 
fill the pollen basket of the opposite legs. As before stated, this 
work is in part performed by a similar but less perfect arrangement 
on the corresponding portion of the middle legs. 
AY, Between the 
i tibia and first 
tarsus of the 
posterior legs 
of the honey- 
bee (Figs. 9 
and 10) is a 
very curious 
joint, remind- 
ing one of a 
steel trap or 
the jaws of an 
animal, the 
tibial or inner 
jaw of which 
is well cover- 
ed with quite 
pronounced teeth. This is used to grasp 
the delicate wax scales from the pockets 
` where they are secreted beneath the abdo- 
men, and transfer them to the mouth 
where they are kneaded into material suit- 
able for comb. 
The claws and pulvilli, which terminate 
the feet of all Hymenopterous insects (Fig: 
8), are specially well developed in bees, 
The former have a strong tooth and are 
useful not only in walking on wood and 
other similar surfaces, but also in holding 
‘ the bees the one to another in case of clus- 
FIG. 10. tering. In such cases the uppermost 
have to sustain hundreds of their fellows, and this often for hours. 
` There are few better examples in the whole animal kingdom of 
what may be accomplished by mere musele.
