INSECTA.

I will not at present add another to their number, but will be 
content to cite the very interesting weevil now before me as an 
aberrant Pentarthrum in which there are no traces of a visible 
scutellum, and none also (beyond the merest rudimentary puncti- 
form specks — of the true existence of which I can scarcely satisfy 
myself, even beneath the microscope) of eyes. 
SUB-FAM. B.HYNCHOPHORIDES. 
Sitopliilus, Schonh. 
S. oryzee, Linn. — Mr. Wollaston writes of this small Weevil: 
“ This almost cosmopolitan spotted Curculionid has apparently esta- 
blished itself at St. Helena, just as it has in the Azorean, Madeiran, 
Canarian, and Cape Verde archipelagos.” 
SUB-FAM. SYNAPTON VC HIDES. 
Nesiotes, Woll. 
Mr. Wollaston says the singular little Curculionids, for the 
reception of which this genus was established, “ are so remarkable 
that I was totally unable to come to any satisfactory conclusion as 
to their precise affinities ; but the invaluable and more recent work 
of Lacordaire has given a position to the group which certainly I 
had little anticipated, but which tallies well with the various details 
of its structure. He regards it as related to the European 'J rack odes, 
and still more so to Echinosoma of Madeira, in the latter of which 
the funiculus is likewise only 5-articulate ; and he consequently erects 
these three genera, together with Synaptonyx from Australia, 
into a little sub-family (under the title of Synaptony chides) of his 
sixteenth tribe, ‘ Tanyrkynckides! This arrangement brings it into 
juxtaposition with one of the most anomalous and endemic of the 
Madeiran weevils, the Echinosoma porcellus ; and it supplies anothei 
instance of that curious analogy by which so many of the most 
extravagant forms of these widely scattered Atlantic islands are 
mysteriously bound together.” 
* In a subsequent paper on the “ Genera of the CossonidaB,” Trans. Ent. Soc. 1873, Pt. IV. 
Oct. p. 525, Mr. Wollaston states that this insect is a new genus, which he describes under 
the name of Pseudomesoxenus, and not a Pentarthrum.
