524 Mr. T. Yernon WoUaston on the 
this genus does not call attention to a single structural 
peculiarity beyond the fact that its funiculus is composed 
of but five joints, I have nevertheless no hesitation in 
identifying it with my JMesoxenus (from the INIadeiran and 
Canarian archipelagos), seeing that his specific description 
of the type, namely the A. Bunnairii {= A. nurhonnensis, 
Bris.), from Corsica and the south of France, seems to 
accord so well Avith an insect now before me, from Corfu, 
tchich is unquestionahly a JMesoxenus, as to leave little 
doubt in my mind that it is even the actual species referred 
to by Fairmaire. This particular example has been com- 
municated by Mr. Janson ; and it is so closely allied to 
the JMesoxenus JBewickianus, from Madeira, that I had at 
first sight imagined it must be identical with it. A more 
critical inspection however has convinced me that the two 
are specifically distinct, though it is impossible to have the 
slightest hesitation in assigning them to at all events the 
same r/roup ; and I do not think, therefore, this being the 
case, that JSIesoxenus should be kept apart from Amau- 
rorrhinus. Nevertheless I ought perhaps to mention that 
Fairmaire makes no allusion whatever to the obsoleteness 
of its eyes, which is the most important feature in the 
insects now before me ; and that he likewise speaks of the 
antenna} as " in medio rostri inserta}," whereas those organs 
are implanted considerably before the middle in the only 
three representatives of my genus JMesoxenus vihich. I have 
hitherto examined. Still, the manifest looseness, and 
brevity, of his diagnosis is sufficient to account for these 
omissions ; and it is my belief, as just stated, that the 
genera in question are identical.* 
Regarding therefore the AmaurorrJiini and JMesoxeni 
as coincident, I may add that the members of this genus 
have the bald, rufo-castaneous, and slightly shining surflice 
of Peutartkrum ; nevertheless their obsolete eyes and 
scutellum, and abbreviated metasternum, throw them into 
a totally different section of the present subfamily. They 
* In size, colour, outline and sculpture, the species from Corfu (which I 
believe to be the A. lionnah-ii of Fairmaire) ahuost exactly resembles the 
!Madciran A. Jictvickiaims, — from which it merely differs in its prothorax 
being a little less widened (or rounded- outwards) behind the middle, in its 
rostrum beinj^ just ajipreciably slenderer and less cx]iandcd in front of the 
anteniuu (which are tlicmselves not quite so thick), in its second fiiniculus- 
joint being perhaps a trille more elongate (though not so much so as in the 
A. MonizianuH), in its club being somewhat less developed, and in its 
metasternum and first abdominal segment being more convex (or hardly 
at all scooped-out, or concave).
