MADETRAN COLEOPTERA, 3 
most minutely and densely subgranulated) all over, especially how- 
ever on the elytra. Head and prothorax rufo-piceous : the former 
with its eyes more prominent, and its neck less elongated, than in 
the D. insularis, and wanting moreover the longitudinal strigse on 
the(less-depressed) forehead : the latter subquadrate, less narrowed 
behind than in that species, and with its margins much more 
broadly and evidently reflexed. Elytra greatly depressed, and 
with the sides parallel (being much less narrowed anteriorly than 
in the D. insularis) ; each with a large, pale, elongated, ill-defined 
dash down its inner disk, and with its outer margin (especially 
towards the apex) more or less pale also; finely striated, the strize 
(which is not the case in the preceding insect) being impunctate ; 
with a distinct series of about seven impressions between the sixth 
and seventh striae, but apparently none between the second and 
third. Limbs pale. The claws much less evidently toothed than 
in the D. insularis. 
A single example of the present Dromius was discovered by C. 
Bewicke, Esq. in Madeira proper (beneath bark in the Cireo at 
S. Antonio de Serra), during March 1856; and he has subsequently 
captured a series of specimens on the hills above Funchal,—viz. 
under the outer fibre of yew-trees at the Mount, and of heaths at 
Camacha. It partakes a little of the characters of the D. marginellus 
and testaceus of more northern latitudes ; nevertheless, apart from its 
different colour, it is rather narrower, flatter, and more-straightened 
than either of those species, its prothorax is a little smaller and less 
margined at the sides, its entire surface is much more alutaceous 
and opake, the longitudinal series of impressions between the sixth 
and seventh strie of its elytra are more regular and distinct, and its 
claws are much smaller and less powerfully toothed. In its com- 
paratively unsculptured forehead, and in the subequal length of the 
two basal joints of its hinder feet, it approaches the latter of those 
species more than the former. The specimens in the British Museum 
were presented by their captor, Mr. Bewicke.

Inhabits Madeira, Porto Santo, and the Dezerta Grande, occurring 
sparingly beneath stones at a high elevation. In Madeira proper it 
has been observed by Mr. Mason beneath the outer fibre of heath— 
trees, under which circumstances he took it on the Pico Ruivo.
