oblique), and with the lateral spine shorter and more anguliform ; 
and its elytra are almost free from the small, punctiform, subglabrous 
spaces which are tolerably evident (and which have a good deal the 
appearance, primd facie, of tubercles) in its ally. 
I have no type at present of the Madeiran O. Bewwkw to compare 
it with, but I feel pretty sure that the Canarian Owypleurus is not 
absolutely conspecific with that insect; though at the same time I 
am tolerably certain, even from recollection, that it is quite as nearly 
related to it as it is to the O. Nodzert.

This European insect has decidedly less the appearance, at the 
Canaries, of having been naturalized than the Hylotrupes bajulus ; 
nevertheless I am doubtful whether it can be regarded as truly 
indigenous. It seems to be extremely rare, and to occur at inter- 
mediate altitudes,—perhaps, however, more abundantly in the old 
Pinals, though in such situations I do not happen hitherto to have 
observed it. Indeed Palma is the only one of the seven islands in 
which I have myself met with it, where, at the beginning of June 
1858, I obtained two or three specimens during my sojourn, in com- 
pany with the Rey. R. T. Lowe, at the Banda. A Teneriffan ex- 
ample, however, stated to have been taken at the Agua Garcia, has 
been communicated by the Barao do Castello de Paiva. It is found 
likewise in Madeira, namely in the various pine-woods which have 
been planted extensively of late years, at a high elevation, on the 
southern and eastern slopes of the island. 
The Canarian specimens have the tubercles on either side of their 
prothorax, and their elytral costz, a trifle more developed than is the 
case in examples now before me from the south of France, and the 
basal rim of their pronotum is a little less thickened and more sinu- 
ated; but I cannot believe that such slight differences are indicative 
of more than, at the utmost, a slight geographical variety.
