Obtecta, shrowded, folded in a crustaceous covering, but in such
a manner, that the head and thorax may easily be distinguished
from that part in which the abdomen is lodged, as in Lepidopterous
insects.
Coardata, straitened, in a globular case, as in the musca fly; the
oestrus, gad fly.
The animal loosed from this last confinement has now its antennae,
becomes then the Imago, or perfect insect, and in most species is immediately
capable of generation.

OR,
THE ORDERS OF INSECTS.
1 H E R E are seven orders of Insects, each of which is denoted
by the following characters :
I. Coleoptera; having four wings, the upper ones, called elytra,

part of the body, and form a line, or suture, down the back of
the insect.

like parchment, and of a softer texture than those of the
former order. They cover .-the body horizontally, with their inner
margins stretched over each other.

imbricated, or covered with scales.The mouth contains the rudiments
of a spiral tongue*;.;...),'- bus - ~n*
