205 TERMINI. 



sent them accurately in this respect (e). De Geer 

 names them " les petits harhillom {/).'* 



Lor a. These parts I have so named from their 

 use, which seems to be to let out or pull in the 

 proboscis; in the latter case, the angle on which 

 the fulcrum of the tube sits points towards the 

 breast (§■), in the other, towards the mouth (A). 

 These are named by Reaumur " les leviers(i)." 



j4nnulus. By this term I distinguish the circum- 

 ference of the gula, in which the lora terminate. 

 The cavity of the former js the bed of the proboscis, 



Collare. I have borrowed this term from Villars, 

 the ingenious author of the Entomohgia Europcea, 

 This part often requires distinct notice in the 

 description of the Fespiform Apes, 



Thorax. I have judged it best to confine this 

 term to that piece which is terminated on all sides 

 by the dorsal sutures. 



Tuhercidi. These, so far as I know, have not 

 been distinguished by a particular name. They 

 differ from the ^'punctum callosum ante alas" of 

 Linneus and others, and are to be found in all 

 the species of the two genera into which I have 

 divided ^/>w; although in most, iho. NomadiB or 

 Fespiform Apes excepted, not easily discoverable.
