THE EARS. 37 



MEMBERS OF INSECTS. 



THE word member lias been chosen here from its 

 involving no theoretical fancy, as the term Appendage, 

 used in modern books, always seems to do. I apply 

 the term member to any part of an insect, either 

 jointed upon the body, or not appearing to make a 

 portion of its surface, such as the legs, wings, and 

 ears, as well as the eyes ; and, by slightly extending 

 the term , it may also include the tail-fork of the ear- 

 wig, and the sting of the bee. 



In describing the members, I shall follow, in the 

 same order as before, the head, corselet, and abdomen. 



MEMBERS OF THE HEAD. 



IT will be most convenient to consider the several 

 members of the head, in the order in which they ap- 

 pear most conspicuous to the eye, beginning with the 

 ears, and proceeding to the eyes, the feelers, the lips, 

 and the jaws. 



The Ears of Insects. 



The members which I here venture to call the ears ( ! ), 

 though not quite proved to be the organ of hearing, 

 are uniformly two in number, standing out from the 

 head, upon which they are jointed and moveable in 

 a socket ( 2 ), by means of a ball or pivot ( 3 ). 



Supposing the head to be composed of a ring made 

 up of determinate pieces, similar to the corselet, the

 applied by the Romans to the sail-yard of a ship. 



(2) In Latin, Torulits. 



(3) In Latin, Bulbits.
