CHAPTER IV. 



OF THE SENSES OF LEPIDOPTEROUS INSECTS. 



THE order lepidoptera includes Butterflies, Sphinges, 

 and Moths. The name of this order was given by 

 Linnaeus from the mealy scales with which the wings 

 are covered. 



There is much difficulty in determining the different 

 organs by which the senses of insects are manifested. 

 This arises from the great physical differences which 

 exist between vertebral warm-blooded animals, and 

 those lower orders of creation without bones, and 

 having cold blood ; so that little can be drawn from 

 analogy. The subject, therefore, is still in much 

 obscurity, notwithstanding the patient investigations 

 of Fabricius, Miiller, Wollaston, Kirby, Spence, and 

 Rennie.
