96 PLATE LXXIL 



And it IS no lefs diftinguifhed for the very fingular {lru£lure and 

 length of its antennae, than for its rarity j that part which forms one 

 of the moft certain charafteriftics of almoft every tribe of Infe(5ls, 

 conftitutes the moft prominent chara(3:er in this. 



Of its ufe, we are altogether ignorant, as the various opinions 

 that have been given by former writers are now obliterated; fome 

 have fuppofed that they were the organs of hearing, or fmell; and 

 others have imagined that they were fufceptlble of the leaft motion in 

 the ambient fluid in v/hich they move. 



GeofFroy dlfcovered the organs of hearing in feveral amphibious 

 animals, viz. in the toad, frog, viper, fome other ferpents, lizard, 

 water-falamander, and fkate * ; and many of the moft eminent ana- 

 tomifts of the prefent time have difcovered by their refearches into 

 the animal kingdom, thofe organs in different creatures. Profef- 

 for Camper, in 1763, publiihcd remarks on the organs of hearing 

 in fifties, in the Harlem Tranfaftions f : Mr. Hunter ■ has defcribed 

 others in the Pnilofophical Tranfailions J j and Dr. Monro has de- 

 fcribed and figured great variety of them in his large work on the 

 ftruclure and phyfiology of fifties. 



Probably, Induced by thofe difcoveries profeftbr Fabiicius endea- 

 voured to afcertaui the organs of hearing in Infects alfo; and about 

 nine years ago publiftied an account of this interefting difcovery in 

 the New Copenhagen Tranfadions §, with figures of thofe organs in 

 the crab and lobfter : he foynd the exteraal orifice of the organ in 

 the(e anim.als to be placed between the long and the fhort antennae, 

 the cochlea, &c. being lodged in the upper part, which Linnaeus calls 

 the thorax, near the bale of the ferrated proji^iion at its apex; we 

 muft therefore conclude that the antennae of Infefe are appropriated 

 for fame other purpofes than thofe it is at prelent fufpecled theyanfwer. 

 The Cerambyx i^dilis, Fabriclus informs us, lives in the trunks 

 of trees ; its horns are n;Oveable, as it can either direft them forward, 

 or fupport them in an eredl pofition ; and when it fieeps, it reclines 

 them along its back ; it aifo reclines them when it walks quick, or has 

 to pais through a narrow track, as the Icaft refiftancefrom any thing in 

 its vvjy, would be very liable to injure, or break them off.
