We now proceed

to treat of insects in like manner. This genus
comprises many species, and, though several kinds are clearly
related to one another, these are not classified under one common
designation, as in the case of the bee, the drone, the wasp, and all
such insects, and again as in the case of those that have their
wings in a sheath or shard, like the cockchafer, the carabus or
stag-beetle, the cantharis or blister-beetle, and the like.

Insects have three parts common to them all; the head, the trunk
containing the stomach, and a third part in betwixt these two,
corresponding to what in other creatures embraces chest and back. In
the majority of insects this intermediate part is single; but in the
long and multipedal insects it has practically the same number of
segments as of nicks.
