LEPIDOPTEROUS INSECTS. 89 
OF HEARING, 
Naturalists are much divided in opinion regarding 
the organs of hearing in insects, and many maintain 
that they are insensible to sounds. The antenne, by 
some, are supposed to correspond to the ears of other 
animals, but as yet no satisfactory proofs have been 
discovered to warrant this conclusion. 
It is well known that insects emit various sounds ; 
but whether these are heard by their congeners, is 
still matter of dispute. We can, however, conceive, 
that if these sounds are not heard, in the strict sense 
ofthe word, yet it is quite possible that they may be 
perceived by the impulses they produce on the 
atmosphere through the medium of the antenne, or 
other organs, which may possess an exquisite sensi- 
bility in this respect. 
After an attentive perusal of all which has been 
written on this subject, we are quite unable to ven- 
ture even an opinion ; and it would only be a waste 
of time to adduce all the arguments which have been 
held on both sides of the question. 
OF VISION, 
Mucu difference of opinion exists among naturalists, 
regarding the extent of vision in insects. In the 
instance of bees, Huber says,— How great is the 
perfection of their organ of sight !—Since, from a 
distance, the bee recognises its habitation, amidst an
