_Ancylotropis waterhousei_ is a good example of the long-horned forms;
it measures over ½ an inch in length, but looks shorter as its head and
thorax are curved downwards. It is a very slender beetle of a uniform
brown tint, but thickly clothed with buff and grey down; the thorax
tapers to the front, and the head is elongated but swells out again in
front, and is furnished with long slender antennae. _Doticus pestilans_
is known as the “Dried Apple Beetle,” from the habit that the beetle
has of laying its eggs in any dried immature apples that are left over
the season upon the trees; in its native state the larvae breed in
the large wattle galls. It measures only about ⅓ of an inch, and is a
short, thickset beetle, with the head turned downward, furnished with
slender clubbed antennae. The general colour is reddish brown; it has
a raised ridge on either side of the wing covers; the fore-legs are
curiously prolonged with large tarsi, and it has a peculiar jumping
habit. Pascoe has described most of our beetles belonging to this group
(Journal of Entomology 1860, and Annals and Magazine of Natural History
1859).

Family 48. Weevils.
CURCULIONIDAE.
The Weevils or Snout Beetles are one of the largest and best defined
groups of the Coleoptera, and though they comprise a great number of
very different looking beetles in shape, they all have the front of
the head produced into a more or less elongated snout with the jaws
placed at the tip, and with the distinctly elbowed antennae standing
out on either side of the snout, forming a regular angle. Most of
them are provided with well developed wings, the elytra being usually
very solid; and the whole insect is encased in thick armour plate
integument. The majority are slow, sluggish beetles, that trust as a
rule more to their shape and protective colouration harmonising with
their surroundings, than to their activity. They feed chiefly upon
foliage and bark, and when at rest cling to the twigs or stalks of
their food plants, falling at the least alarm to the ground, where
they remain perfectly motionless, with their legs and antennae tightly
closed until the danger has passed.
