The Homing of the Hijmenoptera 45 



CONCLUSION 



After studying the subject from all possible angles, the 

 conviction has been reached that iicitlicr the creejnng ant, 

 nor the flying bee, nor the hunting wasp is guided home 

 either by a mysterious lioming instinct, or a combination 

 of tropisms, or solely by muscular memory, but by some- 

 thing which each acquires by experience. As these in- 

 sects journey outward, one or more senses contribute 

 recepts which, functioning as percepts, enable the home- 

 bound insects to recognize certain landmarks and be 

 guided by them.
