have a higher degree of development than in their 

 partners. That this is so with many of the 

 butterflies and moths is very well known. It is 

 also well known that some of the kinds which 

 boast an exceptional development of antennae, 

 have a remarkable power of finding their mates. 

 Such examples as the Emperor and the Fox Moth 

 are familiar to all insect hunters. But whether 

 the action of the organs is by way of hearing or 

 scent has not been definitely discovered. Judging 

 from the moths, hearing seems unlikely, for these 

 insects, with one or two exceptions, make no 

 sounds that we are aware of, although it is pos- 

 sible that they may produce some that our ears 

 are not able to respond to. Bees, on the other 

 hand, undoubtedly do make sounds. There is 

 the curious piping of the young queen already 

 referred to, and the workers make a most variable 

 range of sounds with their wings, sounds which 

 mean something, even to the bee-keeper, who is 

 well able to distinguish between the joyful 

 sound made when swarming and the angry 

 buzzing of a truculent hive. 



It may be, therefore, that the antenna? serve 

 the purpose of hearing, and thus enable bees to 

 communicate with each other in a more or less 

 perfect manner. At all events, as in the other 

 insects, there is a greater development of the 

 antenna? in the males, although it does not ex- 

 tend any further than the possession of an extra
