armed with a sting, à forceps, a bristle, or a kind of claw with a moveable thumb.

Though numberless these insect tribes of air,
Though numberless each tribe and species fair,
Who'wing the noon, and brighton in the blaze,
Innumerous as the sands which bend the seas;
These have their organs, arts, and arms, and tools,
And functions exercised by various rules;
The saw, ax, auger, trowel, piercer, drill;
The neat alembie, and nectareous still:
Their peaceful hours the loom and distaff know:
But war, the force and fury of the foe,
The spear, the falchion, and the martial mail,
And artful stratagem, where strength may fail,
Each tribe peculiar'occupations claim,

Peculiar beauties deck each varying frame. BROOKE. The legs are composed of three parts, connected to each other by joints, and represent the thighs, shanks, ankles, and feet of larger animals.

The wings of insects are so diversified in number, consistence, and colour, that Linnæus has made them the foundation of the seven orders or divisions into which he divides this numerous class of ani- . mals. Some insects are furnished with four, and others with two wings, and some of them are entirely destitute of these instruments of motion.

Classification.

We wonder at a thonsand insect forms,
These hatched, and those resuscitated worms,
New life ordained, and brighter scenes to share,
Once prone on earth, now buoyant upon air. COWPÉR.

Various arrangements of insects have been made by naturalists, the principal of which we shall just glánce 'at before we proceed to explain the Linnean systém. Swammerdam and Ray founded their arrangements ôn the different changes which insects ándorgo, and distribute them into four great divi

sions, agreeably to the different forms under which they appear; Valisnieri has also distributed them into four orders, but accordiny to their habitation; arranging together in one group such as inhabit plants; placing in another, those that live in the water; and in a third, such as conceal themselves under the earth or sand; reserving for his last division, those that inhabit the bodies of other animals. All those systems are defective, in having too few divisions of a class of animals so extremely numerous; the last, however, is liable to an imperfection of another kind, because many insects change their habitation at the moment of their metamorphosis. Some are at first aquatic, but, after their transformation, are seen inhabiting the trees and plants; many of the subterraneous insects in like manner rise into the air as soon as they arrive at their winged state.

The system of Fabricius is built upon the extraordinary variety which exists in the structure of the mouth in different tribes of insects. But the distinction is not sufficiently obvious for a general classification. Other naturalists have thrown out from the province of insects many of those introduced into the apterous order of Linnæus. This has been especially done by Cuvier and Latreille, who have formed a new and an eighth order of the cancer, monoculus, and oniscus tribes, under the name of CRUSTACEA; while Lamarck is dissatisfied that the spider should be regarded as an insect, and continued in the same class'. The Linnwan arrangement is imperfect, but where shall we stop if we change it?

* We must not omit to mention that to Messrs. Kirby, Leach, and Spence, Entomology is indebted for some improvements in the Linnæan system.

ORDER I.–Coleoptera.

Some a twofold apparatus share,
Natives of earth, and habitants of air;
Like warriors stride, oppressed with shining mail,
But furled, beneath, their silken pennons veil:
Deceived, our fellow reptile we admire,
His bright endorsement, and compact attire,
When lo! the latent springs of motion play,
And rising lids disclose the rich inlay;
The tissued wing its folded membrane frees,
And with blithe quavers fans the gath'ring breeze;
Elate tow'rds Heav'n the beaut’ous wonder flies,
And leaves the mortal wrapped in deep surprise.

BROOKE.

· The Coleoptera have a hollow horny case, under which the wings are folded when not in use. The principal genera are:-1. Scarabæus, beetles.-2. Lucanus, stag-beetle'.-3. Dermestes.4. Coccinella, lady-bird?:45. Curculio, weevil.—6. Lampyris, glow-worm 3.—7. Meloe, Spanish-fly.-8. Staphylinus.-9. Forficula, ear-wig.

Like other winged insects, all the beetles live for some time in the form of caterpillars, or grubs:

See the proud giant of the beetle race;
What shining arms his polished limbs enchase!
Like some stern warrior formidably bright
His steely sides reflect a gleaming light:
On his large forehead spreading horns he wears,
And high in air the branching antlers bears :
O'er many an inch extends his wide domain,
And his rich treasury swells with hoarded grain.

It is here worthy of remark, that the same animals, when in the state of caterpillars, live in a different manner, and feed on substances of a very different kind from those they consume after their transformation into flies. The caterpillars of the gardenbeetle, cockchafer, &c. lead a solitary life, under ground, and consume the roots of plants. Those of others feed upon putrid carcases, every kind of flesh, dried skins, rotten wood, dung, and the small insects called pucerons, or vine-fretters. But after their transformation into flies, many of the same animals, which formerly fed upon dung and putrid carcases, are nourished by the purest nectareous juices extracted from fruits and flowers. The creatures themselves, with regard to what may be termed individual animation, have suffered no alteration. But the fabric of their bodies, their instruments of motion, and the organs by which they take their food, are materially changed. This change of structure, though the animals retain their identity, produces the greatest diversity in their manners, their economy, and the powers of their bodies.

The scarabeus melolontha, or common chaffer, well known in this and other countries, flies at dusk with a rash and noisome impulse; lives upon the first budding leaves of the elm tree, and, when caught, is often tormented by children, who, placing a paper fixed with a pin at one of their legs, enjoy the cruel pleasure to see them turn round a piece of wood! It is a great pity, that in our earliest days we are not properly taught, that pleasure to one of the creation should never be sought out of the pain felt by another. There is a sort of barbarity in tormenting animals, which is too often indulged in infants, and is generally the sad prognostic of a tyrannical disposition, which grows and increases by degrees. Who ever thought that the boy, who, in the palace of the Cæsars, amused himself with the innocent pastime of torturing common flies with a pin, would, when a man, order his mother to death, and set fire to the imperial town of Rome? In these puerile trifles were concealed the dreadful stamina of the most execrable and most wanton cruelty.

Many caterpillars, previous to their transformation, live even in a different element. The ephemeron fly, when in the caterpillar state, lives no less than three years in the water, and extracts its nourishment from earth and clay. After transformation, this animal seldom exists longer than one day, during which myriads of eggs are deposited on the surface of the water. These eggs produce worms or caterpillars, and the same process goes perpetually round.

ORDER II.--Hemiptera.

Some multipede, earth's leafy verdure creep,
Or on the pool's new mantling surface play,
And range a drop, as whales may range the sea :
Or ply the rivulet with supple oars,
And oft, amphibious, course the neighb'ring shores;
Or shelt'ring, quit the dank inclement sky,
And condescend to lodge where princes lie;
There tread the ceiling, an inverted floor,
And from its precipice depend secure;
Or who por creep, por fly, nor walk, nor swim,
But claim new motion with peculiar limb,
Successive spring with quick elastic bound,
And thus transported pass the refluent ground.
Or who all native vehicles despise,
And buoyed upon their own inventions rise;
Shoot forth the twine, their light aerial guide,
And, mounting o'er the distant zenith, ride. BROOKE.

Insects of the second order have four wings, but the upper pair, instead of being hard and horny, rather resemble fine vellum. They cover the body horizontally, and do not meet in al direct line, forming a ridge or suture, as in the beetle tribe. The whole of this order are furnished with a proboscis or trunk
