Mr. T. V. Wollaston on the Canarian Longicorns. 101 
The common European H. bajulus, which has been imported like- 
wise into Madeira, I have taken occasionally in Teneriffe, principally 
in the streets of S** Cruz, where it is undoubtedly a mere introduc- 
tion from more northern latitudes. Teneriffan examples have also 
been communicated by the Barao do Castello de Paiva. 
Genus BLaBInorus. 
Wollaston, Ins. Mad. 425 (1854). 
Although very nearly allied to Oxypleuwrus of Mulsant, for a type 
of which (the O. Nodier?) I am indebted to Mr. Pascoe, I believe 
that the present genus is truly distinct from it. In their cylindrical 
bodies and laterally-spinose prothoraces, as well as in their colour, 
sculpture, and clothing, the two genera are almost identical. Never- 
theless, whilst Oxypleurus has the eyes enormous (extending over a 
large portion of the head, both above and below), very deeply exca- 
vated internally and by no means prominent, the head convex, and 
the antenne widely separated at their base, Blabinotus, on the con- 
trary, has the eyes comparatively small, and consequently remote 
from the antenne, hardly at all scooped-out, and excessively pro- 
minent, the head more uneven, and the antennz more approximated 
at their base. In Oxypleurus, likewise, the prothorax is short, sub- 
sinuate and drawn-in (or truncated) at its anterior edge, and (with 
the exception of the lateral spine) is rounded, even, and convex, 
and the antenne have their third joint perceptibly shorter than the 
fourth ; whereas in Blabinotus the prothorax is more elongate, ele- 
vated (and, if anything, somewhat produced) in the centre anteriorly, 
binodose on its disk and extremely uneven, and the third antennal 
articulation is a trifle longer than the fourth. With external differ- 
ences such as these, I think it is more than probable that an accurate 
comparison of the oral organs of the two groups would tend still 
further to remove them from each other. I believe, however, it will 
be found, on a closer examination, that, whilst Blabinotus, as repre- 
sented by the B. spinicolls, is undoubtedly distinct from Oxvypleurus, 
the insect which I described (Cat. Mad. Col. 126, 1857) as the B. 
Bewickit is probably a member of the latter. 
Although I am not aware under what circumstances the Oxypleurt 
are usually to be met with in southern Europe, it is at least inter- 
esting to remark that, so far as I have myself observed, the habits 
of the two genera are distinct,—Owypleurus (as represented by the 
Bewickii at Madeira and the pinicola at the Canaries) being confined 
to the pine-trees, whilst Blabinotus (also existing in both groups) is 
no less exclusively attached to the various laurels.
