-Scopoli, as well as the great Linnzus, defcribes the softrum as 
bivalve. {am loth to diffent 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 proteéts it 
beneath, ‘to which it adheres (z). 
I never was fo fortunate as to meet with the variety of this infec 
mentioned by Linnaeus, abdominis dorfo nigro. It is poflibly a dif- 
tinct {pecies. Villars; the ingenious author of the Entomologia 
Europea, mentions another, ped:bus quatuor gnticis fulvis. 1 fhould 
likewife think this more than a variety.
