t02 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 antennae, with 

 far more of the olfactory cavities, though not so many tac- 

 tile hairs as are found in the antennae 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. We can 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-cells in bundles. As Leuckart shows, the testes are 

 larger in the pupa than in the imago, for even then the
