MADEIRAN COLEOPTERA. 181 
within the inhabited districts, and principally at low elevations. It 
is on the authority of the last edition of the Stettin Catalogue (1856) 
that I have assigned the name of puberula to this Aleochara,—with 
the description of which, however, in Erichson’s Genera et Species 
Staphylinorum, it agrees sufficiently well. The fact of its having 
been recorded by Klug amongst the Coleoptera of Madagascar is not 
so surprising as at first sight might appear, since there are few 
insects more liable to artificial transport than the Aleochare (some 
of which have established themselves in the most distant parts of the 
world); and it is very possible therefore that it may have been acci- 
dentally naturalized in that island during the period of its com- 
mercial intercourse with Europe. It is found also, I am informed by 
Dr, Kraatz, in Italy ; and I may add that it has all the appearance 
of having been introduced, within a comparatively recent period, 
into the Madeiras.

at low and intermediate elevations.

A, sublinear, deep-black, shining, and coarsely pubescent. Head 
and prothorax uniformly punctured all over, but with the punc- 
tures more numerous on the latter than on the former. Hlytra a 
little more closely and coarsely punctured than the prothorax, and 
concolorous. Abdomen with its upper surface only slightly punc- 
tured. Antenne rather long; robust at their apex: their base, 
and the femora, piceous. Tibie and tarsi piceo-testaceous. 
The single specimen (now in the British Museum) from which the 
above description is compiled, and which has been identified by 
Dr. Kraatz with the European A. mesta, was detected by myself in 
the Ribeira de $'* Luzia (in the south of Madeira proper), during the
