102 Organs of Drone. 
The facets or simple eyes which form the compound eyes 
of the drone (Fig. 8), are, as shown by Lacodaire, more 
than twice as numerous as those of either queen or worker. 
The drones also have longer and broader antenna, with 
far more of the olfactory cavities, though not so many tac- 
tile hairs as are found in the antenne of the workers. En- 
tomologists now believe that the better sight and smell, as 
also the large wings, are very useful to the drone. They 
make success more probable, as the drone flies forth with 
hundreds of other drones in quest of a mate. Wecan also 
see how, through the law of natural selection, all these 
peculiarities are constantly strengthened. Their posterior 
legs are convex on the outside (Fig. 30), so, like the queens, 
they have no pollen baskets. As we should expect, the

webbed hairs, both on the body and legs, are almost absent 
in drones; what there are are course, and probably aid in 
mating. The drones are without the defensive organ, hav- 
ing no sting, while their special sex-organs (Fig. 22), are 
very interesting. ‘These have been fully described and 
illustrated by Leuckart. The testes are situated in the 
abdomen, in an analogous position to that of the ovaries in 
the queen. Like these organs in higher animals, there are 
in each testes hundreds of tubes in which are developed the 
sperm-cellsin bundles. As Leuckart shows, the testes are 
larger in the pupa than in the imago, for even then the
