264 Dr. Afzelius'i Obfervations on the Genus Paufus. 



defcriptions only from the mouth and the organs for feeding, or 

 what he calls Inftrumenta cibaria. Thefe defcriptions he has pub- 

 lifhed in his Genera InJeSlorum, under the name of CharaSleres 

 natura/es, in imitation of what Linne had done before in regard 

 to plants. 



But as a CharaSler naturalis, in whatever manner it may be 

 made out, does not contain the whole defcription of a genus, or the 

 whole account of the agreement between its fpecies, I would call 

 the remaining part Habitus naturalise and from the leading points 

 of this double ftatement I would form a CharaSler artificialis^ to be 

 put before the genus in the text of the book, leaving what is 

 named CharaSler ejfentialis, or the mod diftinguifhing marks from 

 other genera, out of CharaSler naturalh, to be inferted as ufuai in 

 the methodical arrangement at the head of the clafs. 



But Pauf us is a genus fo very unlike all others hitherto known, 

 that I cannot find a place for it in this arrangement. Gmelin has 

 put it in the divifion, Antennis clava folida ; and Fabricins with Cero- 

 coma in another, Antennis moniliformibus. But, as I have proved 

 above, it does not belong to either ; nor can it be placed amongft 

 Fabricius's genera Antennis extrorfum crajioribus, becaufe thefe expref- 

 fions, without being otherwife defined, are fo vague that they may 

 be equally applied to all infe&s with clavated antennas, as it has 

 been done not only by Linne, but alfo by Fabricius himfelf in his 

 Philofophia Entomologica. I am therefore under the necelTity of mak- 

 ing a new divifion for Paufus.
