50 Mr. T. V. Wollaston on Additions to Madetran Coleoptera. 
accordingly ; nevertheless, if it should prove hereafter to be di- 
stinct from that insect, I would propose for it the trivial name 
of falcatus—in allusion to its narrow and sickle-shaped mandi- 
bles, which (inéer alia) immediately distinguish its male sex from 
the corresponding one of its ally. It would seem that the female 
is the scarcer sex of the two; for out of the twenty-one exam- 
ples from which the above description has been compiled, seven 
are females and fourteen males. And, indeed, the same appears 
to obtain in the G. cornutus also, since, of eleven Madeiran exam- 
ples now before me, three only are females.

Habitat Maderam orientalem, in illa prominente litoris calcaria ad 
Porto da Cruz, sub lapidibus juxta mare jacentibus, d. 18 Jan. 
1859, copiose inveni. Species valde distincta, et in honorem Baronis 
ejus Lusitanici ‘‘ Castello de Paiva” a me amica mente citata. 
H. oblong (being of almost the same outline as the H. alpinus), 
black, almost free from scales, and rather more coarsely, and 
less closely, granulated all over than the H. alpinus, but not near 
so coarsely as the cinerascens. Head with the clypeus expanded 
into a lateral angle in front of the eyes, as in the latter species, 
instead of being rounded-off, as in the former one. Prothorax 
of the same shape as that of the cinerascens, being a trifle more 
expanded anteriorly than in the alpinus, and not quite so broadly 
flattened at the sides. Klytra very obsoletely striated, but rather 
more perceptibly so than in the alpinus, and, under a high 
magnifying power, beset with an excessively short, minute, and 
distant fulvescent pile. Antenne and tarsi obscurely picedus. 
As will be perceived from the above description, the present 
Hadrus is intermediate in its features between the H. alpinus and 
cinerascens (though remarkably distinct, and never merging into 
either of them)—combining the general outline of the former 
with the angulated clypeus of the latter; whilst in the relative 
coarseness of its sculpture (though not in its precise character) it 
is about midway between the two. In the pubescence of its 
elytra, also, which is very delicate and obscure, it is intermediate 
between the totally unclothed H. alpinus and the rather more 
evidently (though very minutely) setulose and roughened surface 
of the H. cinerascens. It was detected by myself, on the 18th of 
eee ered eee ee Ome
