242 Mr. T. Vernon Wollaston on 
IT have lately examined 203 examples of it (taken during 
the last winter and spring in the chestnut-woods at 
‘the Mount,” above Funchal) without being able to dis- 
cover a single individual which has even the slightest 
tendency to a spiniform development about the feet, and 
it is hardly likely that amongst such a mass of material 
both sexes should not be represented,—more particularly 
since in the case of the true inornatus (found in the more 
central and northern districts of the island) the males 
and females are numerically in about equal proportions. 
And indeed if we further take into account the imdivi- 
duals which I overhauled a few years ago, I must have 
seen, at the very lowest computation, 250 of them, and 
have yet been unable to detect any trace of the particular 
structure which is so conspicuous in the inornatus, and 
which we have been now considering. 
(Sp. 348) Larphius Wolffir. 
The excessive difficulty attending the determination of 
some of the Tarphii, and (above all) the separating of 
the sexes in certain of the unarmed species, must be my 
excuse for feeling compelled to suppress the present one 
—which was founded in 1865 on two Madeiran examples 
which were taken by Dr. C. Wolff in the chestnut-plan- 
tations at “the Mount,’ aboye Funchal. Even now, 
however, I cannot but acknowledge the very great prima 
facie difference which exists between small and compara- 
tively un-nodose specimens (such as those from which 
my diagnosis of the 7’. Woljii was drawn out) and the 
much larger and more roughened ones which seem 
nevertheless to merge gradually into the others, and 
which represent the species which I described (from a 
unique individual, in 1854) under the title of rugosus. 
Yet remembering how greatly the sexes in many of the 
forms recede from each other, both in size and develop- 
ment of their elytral callosities, I have little doubt (after 
a careful inspection of fifty individuals which were taken 
at “the Mount” during the past winter and spring) that 
the smaller ones, in which the lumps are less elevated 
(though usually more rufescent), and which constitute 
my I’. Wolffii, are merely the (unarmed) males of the 
larger and rougher ones; and I would therefore sink the 
T. Woljjic as a synonym of the previously-enunciated 1’.
