a new Genus of InfeSbs, z 05 



Scopoli, as well as the great Linnaeus, defcribes the roftrum as 

 bivalve, f am loth to differ* from fuch high authorities ; but I am 

 convinced, from repeated examination, that the roftrum in this and 

 moft hymenopterous infects confifts of three valves befides the 

 tongue ; two which cover its upper furface, and one that protects it 

 beneath, to which it adheres (/). 



I never was fo fortunate as to meet with the variety of this infect 

 mentioned by Linnaeus, abdominis dorfo nigro. It is pofTibly a dif- 

 tina fpecies. Villars, the ingenious author of the Entomologia 

 guropaa, mentions another, .pedibus quatuor antich fulvis. I fhould 

 likewife think this more than a variety.

infetf, which was compofed for a Society of which he was a member, before the Linnsan 

 waseftablimed; what comes from the pen of fo learned and accurate a Naturahft, muft 

 be extremely valuable, and therefore I cannot help indulging a wifh that the public may 

 be put in pofleffion of this curious and interefting- paper.
