Atlantic Coleoptera. 297 
fore, with the S. anale into a tolerably well-defined group. 
Indeed M. Fauvel (J Abeille, vi. 150) actually identified 
it with Kraatz’s O. wanthopyga; but as nearly every 
species which Fauvel has hitherto examined for me, from 
these various Atlantic islands, has been returned with a 
most unmistakeably false determination, I have no con- 
fidence whatever in his dictum as regards Somatium. 
p. 478 (genus Conosoma). 
(Sp. 1819) Conosoma pubescens. 
Without assigning his reasons for the change, Mr. 
Crotch enters this common 'Tachyporid into his Azorean 
Catalogue as the “ sericeus, Latr.’* Strictly, no doubt, 
Paykull’s title of pwhescens (under which it has almost 
universally been acknowledged) cannot be retained, for 
there was already a “ Staphylinus pubescens” published 
by De Geer in 1774; but as the latter falls now into a 
totally different genus (—being a true Staphylinus) , and 
the present Conosoma is invariably recognized under the 
trivial name of pubescens, | hardly think that it is abso- 
lutely necessary to disturb the commonly-received no- 
menclature. 
p. 482 (genus Mycrrororvs). 
(Sp. 1328) Mycetoporus Johnsont. 
During our late sojourn in Madeira I took several ex- 
amples of a Mycetoporus throughout the elevated region 
of S. Antonio da*Serra (chiefly by sifting fallen leaves 
and rubbish) which seem to differ a little from the or- 
dinary ones of the M. Jolnsoni, yet not sufficiently so, I 
think, to be treated safely as representing more than a 
slight variety, or state, of that species. I will however 
give a short diagnosis of it as a “var. 8,” assigning to 
it at the same time a varietal, or subspecific, name—in 
the event of further material rendering it desirable, at 
any future time, to cite it as distinct. It appears, on the 
average, to be a trifle larger and darker than what I have 
hitherto regarded as the M. Johnsoni type,—its antenna 
. *T cannot but think that this must be a misprint, and that Lacordaire 
(Faun. Ent. Paris, i. 519; 1835), not ‘‘ Latreille,” was intended.
