either dark or piceovis, in hue (more often the former) ; 
and some of them have a very faint brassy tinge ; and, 
unlike the Rliyncoli, certain of the species (though by no 
means the majority of them) iire sparingly pubescent. 
They appear to be Avidely distributed over the Avorld ; 
and although specifically few in number throughout 
Europe, they are rather unusually dominant in some of 
the islands of the Atlantic archipelagos.* 
43. PsEUDOPHL(EOPHAGUS {noi\ ijen.). — This genus, 
Avhicli is established to receive the Pliloeoplicu/us tenax 
from INIadeira and the Azores, combines in a remarkable 
degree the structural peculiarities of Rliyncolus and 
Plil(jeo])]iagus, — agreeing with the former in its more 
parallel outline, less inflated body, and conspicuous (though 
rather small, transverse, and sub-perpendicular) scutellum ; 
but with the latter in its abbreviated metasternum, and in 
its comparatively slender antennae and tarsi, the first of 
■which have (as in Phlceophar/us^ their second funiculus- 
joint appreciably longer than those Avliich follow it, and 
their club enlarged and abrupt, whilst in the feet the basal 
articulation is considerably lengthened, and the third one 
minutely bilobed. In its greatly approximated anterior 
coxjB it is more on the Phloeoj)hagus than the Rhijncolus 
pattern, and in its sericeous surface it is likewise more in 
accordance with (at any rate a certain section of) the 
former ; but its coxa? are, if anything, still less separated 
than in even the Phloeopliafji (the front ones being practi- 
cally contiguous), whilst the minute keel, or lobe, of its 
mesosternum (between the intermediate coxa?) appears to 
me to be more developed than in either of those groups. 
Its type (the P. tenax) is a very common insect in the 
higher elevations of iNIadeira, where it occurs in great pro- 
fusion in the rotten wood, and beneath the bark, of old 
trees, — more particularly those of the laurel tribe ; and it 
has been met with also in the Azorean archipelago. 
* The European P. (rneopU'Ciis is a less typical member of the group 
than the various other species which I have examined ; for not onlj' does 
it recede in outline from the hitter, but it has also manifest indications of 
a scutellum, — which, although not very easy to be detected, is certainly 
appreciable. Indeed, 1 am not (piite sure thnt it would not be more natural 
to admit it (along with the tciui.r, from Madeira and the Azores) into the 
genus Pxeudnphhvophafius ; nevertheless since the characters alUuled to are 
not very pronounced ones, I will not disturb it in its usually-received 
position.
