308 SENSES OF BEES. 



insect with a sixth sense, an intermediate faculty, 

 according to MESSRS. KIRBY and SPENCE, between 

 hearing and touch, rendering it sensible of the 

 slightest movement of the circumambient air. 

 DR. EVANS designates the antennae as their sight- 

 supplying sense ; 



" The same keen horns, within the dark abode, 

 Trace, for the sightless throng, a ready road, 

 While all the mazy threads of touch convey, 

 Shot inward to the mind, a semblant day." 



EVANS. 



The antennae, of which there are only a single 

 pair, proceed from the anterior part of the head 

 before the eyes. 



The PALPI are generally considered as the true 

 feelers ; which, as well from their texture as from 

 the manner in which insects apply them to their 

 food before they begin to eat it, seems probable : 

 Cuvier and Lehmann were of this opinion. The 

 palpi are attached to the under jaws and lips, and 

 are four in number. In some respects they 

 bear analogy to the antennae ; but the latter, 

 being more articulated, have an extended power 

 of motion. Some insects with small antennae 

 are observed to have very large palpi, which 

 gives reason to suppose, that although their offices 

 may be different, they are intended to assist 

 each other.
