ORDER II.—BUGS. 63 
senses, with internal and external faculties, and constituted 
them equally essential parts in the vast economy of Nature. 
Bugs are easily distinguished from other insects by hay- 
ing, instead of a mouth, a prolongated horny proboscis, or 
snout, in which are two pairs of bristles which they insert 
into the animal or vegetable body, from which they derive 
their nourishment by pumping out its juices. This pro- 
boscis is articulated to the head, and when in operation has 
a perpendicular, but when not in use, a horizontal position, 
being attached to the under part of the breast. Their head 
is usually small, and has two short feelers (antenne); their 
breast larger than the head, and the hind body is short and 
wide. All the insects of this Order, the Bed-bugs and fe- 
male Plant-lice excepted, have four wings, which are erect- 
ed, as in the Cicada, known under the name of Locust, or 
folded up, as in the Squash-bug (Coreus tristis). 
Bugs do not metamorphose themselves into Caterpillars, 
like Butterflies; or into grubs, like the May Beetles; or 
into maggots, like Bees and Flies. They make no cocoons 
or chrysalis, but they burst from their eggs in an almost 
perfect condition—that is to say, with six legs and a pro- 
boscis, but without wings. .The Cicadas form the only ex- 
ception to this natural rule, and probably live in a larva 
state more than two years in the ground. 
These insects feed mostly on the juices of plants; but 
some of them pump out the circulating fluid of insects, and 
even the blood of warm-blooded animals, on account of 
which they become very annoying and troublesome to man. 
Some of this order also give out a peculiarly unpleasant 
odor when mashed, an odor that is often perceived in the 
mouth when eating raspberries, blackberries, or any other 
berries, and which is occasioned by masticating with the 
fruit the eggs which these insects have deposited upon it, 
and which are not easily detected by the sight. I once 
heard a country woman consoling her little boy, who com-
