Insects are a class of invertebrate articulated animals, forming one of the four divisions com prised in the Arthropoda of naturalists, the four divisions being 1. by means of gills, or by the general surface of the body ; two pairs of antenna; locomotive appendages more than eight, borne by the segments of the thorax, and usually of the abdomen also. lobsters, shrimps, wood-lice, etc.
2. Arachnida. —Respiration by pulmonary vesicles, by or by the general surface of the body ; bead and thorax united ; antennae absent ; legs, eight ; abdomen without locomotive appendages.
Examples—Spiders and scorpions.
3. by trachea ; head distinct ; the remainder of tho body composed of nearly similar segments ; ono pair of antenna) ; loge numerous. Examples—Centipedes and inillepedes.
4. Inseeta.—liespirstion by trachea); head, thorax, and abdomen distinct ; one pair of antenna); three pairs of legs borne by the thorax ; abdomen with out limbs. Tho adult form (with a few exceptions) winged. Exampfea—Beetles, bees, wasps, flies, butterflies, locusts, cockroaches, earwigs, dragon flies, ant-lions, May-flies, bugs.
The Insecta are divided by naturalists into the following sub-classes:— 1. AME•ABOLA.—Young not passing through a meta morphosis, and differing from the adult in size only ; imago destitute of wings.; eyes simple, sometimes wanting.
11. Hen ISIETABOLA.—Metamorphosis incomplete ; the larva differing from tho imago chiefly in the absence of wings, and in size ; pupa usually active, or, if quiescent, capable of movement.
Hotonirranor.a. —Metamorphosis complete ; the larva, pupa, and imago differing greatly from one another in external appearance. The larva vermiform, and the pupa quiescent.
I. The AMETABOLA are divided into thofollow ing orders:—
