Entomologists 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 con- FiG. Beads of Worker, Queen and Drone, showing comparative length of Tongues, from Cowan.

As we should expect, the branching hairs, both on the body and legs, are almost absent in drones ; what there are are coarse, and probably aid in mating. The drones are with- out the defensive organ, having no sting, while their special sex-organs (Fig. 37) are very interesting. These have been â fully described and illustrated by L,euckart. The testes are situated in the abdomen, in an analogous position to that of the ovaries in the queen. Like these organs in higher ani- mals, there are in each testis hundreds of tubes in which are developed the sperm-cells in bundles. As L,euckart shows, the.
