BRITISH BEETLES. 
to Q. dilatatus , found in rotten fungi and dung in the 
autumn, is shining-black, with the reflexed side- 
margins of its elytra yellowish. Q. truneicola, emeri- 
tus (Plate IV., Fig. 3), s situs, and laevigatus, are all 
subcortical species ; the latter, a flattened, polished 
insect, occurs under pine-bark in Scotland ; it has 
lately been referred by Dr. Sharp to a new genus, 
Quedionuchus. 
The remaining species (with the exception of the 
little Q. auricomus, conspicuous from its abdomen 
being striped with rows of fine golden or silvery pu- 
bescence, and which is found in wet moss, &c., near or 
in waterfalls) offer no peculiarity of structure or habit : 
they are mostly dull in colour, though sometimes 
having red elytra, and occur in moss, haystacks, dead 
leaves, dung, &c. 
The Stagrhijlinina have the prosternum connected 
with the sides of the thorax at the anterior angles 
which are not free ; the antennas distant at the base 
and inserted in front, within the base of the mandi- 
bles ; and the thorax with a lateral marginal line, 
both on the upper and under side. Their mandibles 
are generally lai’ge, the maxillary palpi filiform, the 
ligula small and rounded, entire in Philonthus, but 
emarginate in the other genera, and with the para- 
glossm always long. The males are usually known by 
their larger heads and dilated anterior tarsi, and by the 
penultimate segment of their abdomen being slightly 
notched on the under side. The different species are 
found under stones, in dung, can-ion, or decaying 
vegetable matter, or flying in the hot sunshine. 
Creojihilus maxillosus, a common large carnivorous 
insect, may often be seen in dead animals. It runs
