BRITISH BEETLES. 
in the pupa state, changes to the perfect state ; stay- 
ing as such in its nest until the following summer. 
The species of Pogonocherus are very much smaller, 
having the elytra slightly hairy, generally spined at 
the apex, and with the front greyish-white. They 
are beaten out of bundles of old twigs and faggots in 
hedges. 
In the Saperdina, which are all more or less cylin- 
drical, the femora are not clavate ; and the thorax, 
which has no spine at the sides, is continuous in out- 
line with the elytra, being, moreover, deeply sinuated 
on the sides beneath. 
Here are situated some of our most handsome 
species ; notably Saperda scalaris (Plate XIII., Fig. 5), 
a very beautifully coloured insect, occurring near 
Manchester and at Raunoch ; it has also been found 
near Burton-on-Trent. 
Of the other Swperdse , — which appear to affect 
aspens, poplars, and willows, — carcharias (found in 
fenny districts) is remarkable for its large size and 
uniform yellow-ochreous tint ; and populnea, a hairy, 
minutely speckled insect, common near London on 
young aspens, is readily found in its larval state by the 
round swollen knobs which it makes in the stems of 
that tree. 
Agapanthia lineatocollis, which may be known by 
its very long twelve-jointed antennae, has been taken 
near Lincoln in numbers on the Cow-parsnip ( Hera - 
cleum spondylium ), and Oberea oculata, conspicuous 
by its red thorax, which is furnished with two black 
tubercles on its disc, used to be found not uncom- 
monly on sallows in the Cambridge Fens, but has 
not been recorded for many years from its old
