Observations on the various Insects 
of 12 transverse segments; the tail is somewhat conical, and it 
has 6 articulated legs : the pupa (fig. 23 ; J, the natural length) is 
of the same colour ; the head is bent down ; the thorax is subor- 
bicular with Bridges; the sides with a few short spines : scutellura 
elongated ; elytra wrapped over the sides and striated ; abdomen 
with distinct segments, the sides with short thick points like the 
thorax. 
Mr. Ingpen bred this insect from bran he received from Scot- 
land ; and it appears to be naturalised, from its being found in 
various parts of England and Scotland under the bark of trees. 
Cucujus TESTACEUS — The Corn Cucujus. 
This is a still smaller beetle, which accompanies the corn- 
weevils, and was found by Mr. C. C. Babington in a granary at 
Cambridge in great abundance, and a closely allied species, or it 
may be the other sex merely, was observed in granaries and corn- 
bins in Norfolk about 30 years back in the month of December ; 
at which period Mr. Ingpen detected it in an old decayed elm- 
tree in Wiltshire. The C. testaceus, however, is decidedly a corn- 
feeding insect, for in examining the wheat from Ancona and 
cutting open the grains, 1 found two with the Cucujus in them, as 
shown by the cavity at the top of fig. 13, and more distinctly 
exhibited at fig. 14 p: in this cell, which is opposite to the point 
occupied by the corn-weevil, the Cucujus was lying dead, and 
there were 2 or 3 little holes in the skin of the wheat as minute 
as the point of a needle. 
This beetle belongs to a small Family called Cucujid*, 
which comprises the Genus Cucujus, and from the colour of 
the insect it has been named by Fabricius 
10. Cucujus testaceus (fig. 26) : it is only 1 line long (fig. m), 
very narrow and depressed, finely but not thickly punctured, and 
clothed with short, soft, ochreous pubescence, and is of a bright 
shining testaceous colour : the head is broad, with a small black 
eye on each side towards the base ; it is narrowed before, and to 
the nose is attached the labrum, under which are 2 toothed jaws, 
2 maxillae and palpi, and an under lip with 2 more palpi ; before 
the eyes are placed the antennae, which are longer than the head 
and thorax, straight, moniliform, hairy, and 11-jointed; basal 
joint stoutish and oval, the following more or less globose, the 
three last thickened, top-shaped, and forming a somewhat elon- 
gated club, the terminal joint having a little hairy tubercle at the 
tip : thorax rather broader than the head, somewhat quadrate, but 
a little narrowed behind, with the angles acute, the sides margined: 
scutellum small and transverse : elytra very much depressed, 
elliptical, often slightly concave, broader than the thorax and 
nearly thrice as long, concealing two ample folded wings: legs 6,
