THE MOUTH. 



45 



fauces, resting upon the tonguelet, with a tip like a 

 small ear. 



Parts of the mouth in a beetle, a, the upper lip ; b, the upper 

 jaws ; c, the under jaws, with two pairs of jointed feelers; d, the 

 under lip, with the short tongue in the middle, the chin below 

 this, and a pair of jointed feelers. 



In bees, the under jaws are rather long, encasing 

 the sides of the lip, and these, being united, form a 

 sort of sucker, moveable at the base. Cuvier mistook 

 the under lip for the tongue. 



In butterflies and moths, the upper jaws and the 

 upper lip are very minute, the under jaws immoveable 

 at the base, and form two lines which are united and 

 form a long tube rolled up spirally. It would be no less 

 incorrect to call this the tongue, as it has been called 

 byFabricius, Latreille, and Cuvier, than it would be to 

 represent it as an imperfect mouth, as has been done
