CHAPTER IV. 
OF THE SENSES OF LEPIDOPTEROUS INSECTS. 
Tue order /epidoptera includes Butterflies, Sphinges, 
and Moths. The name of this order was given by 
Linneeus from the mealy scales with which the wings 
are covered. 
Thereismuch 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 
haying 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. 
OF TOUCH, 
Mosrnaturalistsarenow of opinion, that the organs 
of touch, in insects in general, are the antennee and 
palpi, or what have usually been called the feelers.
