MADEIRAN COLEOPTERA. 59 
Cryptophagus by the tarsi of both of its sexes being pentamerous, 
and by the excessive minuteness of their penultimate joint. 
165. Paramecosoma simplex, n. sp. 
P. oblongum pallido-ferrugineum punctatum, pube subdepressa dense 
vestitum, capite prothoraceque vix obscurioribus, hoc transverso- 
quadrato, ad latera eequaliter rotundato et (oculis imarmatis) 
integro.

P. oblong, pale-ferruginous, and densely clothed with a fine and sub- 
depressed pubescence. Head and prothoraw generally a tinge 
darker (or more ferruginous), and a little more deeply punctured, 
than the elytra: the latter transyerse-quadrate, and almost as 
broad as the elytra, being very slightly (and about equally) 
narrowed before and behind,—and with the sides, consequently, 
equally, though slightly, rounded; the edges, to an ordinary lens, 
entire (being free from the teeth and projections observable in 
the Cryptophagi), but when viewed under the microscope appear- 
ing minutely and obsoletely crenulated. Antenne concolorous 
with the head and prothorax : legs paler. 
This insect, which, from its outward contour and pallid hue, might 
be mistaken for a Oryptophagus (but which may be at once distin- 
guished by the generic peculiarities mentioned above), has the edges 
of its prothorax more simple than any Paramecosoma with which I 
am acquainted ; and it is only when viewed beneath the microscope 
that they are found to have any inequalities at all,—being then 
observed to be obsoletely crenulated along their entire length. The 
species was detected by myself, in Mr. Phelps’s garden, in Funchal, 
during the summer of 1855, where it was abundant,—especially, 
however, on the wing, and just after sunset.

Hypocoprus Motschulskii, Woll., Ins. Mad. 174 (1854). 
Inhabits Porto Santo, where it was detected by myself, in 1849, on 
the slopes of the Pico d’Anna Ferreira. Exceedingly rare.
