what it does to us. 
The Sense of Hearing. 
Many eminent observers have regarded the antennee 
of insects as auditory organs, and have brought forward 
strong evidence in favour of their view. 
I have myself made experiments on grasshoppers, 
which convinced me that their antenne serve as organs 
of hearing. 
So far, however, as Ants, Bees, and Wasps are con- 
cerned, the evidence is very conflicting. The power of 
hearing has indeed generally been attributed to them. 
Thus St. Fargeau, in his ‘ Hist. Nat. des Hyménoptéres,’! 
thinks there can be no doubt on the subject. Bevan 
expresses, no doubt, the general opinion with reference 
to Bees, when he says that ‘ there is good evidence that 
Bees have a quick sense of hearing.’ ” 
As regards Wasps, Ormerod, who studied them 
so lovingly, came to the same conclusion.’ 
On the other hand, both Huber‘ and Forel ® state 
that ants are quite deaf. As I have already men- 
tioned in the ‘Linnean Journal’ (vols. xii. and xiii.), 
I have never succeeded in satisfying myself that my 
ants, bees, or wasps heard any of the sounds with
