THOSE animals which by their fize chiefly attract our attentions, are but the fmalleft part of animated nature ; the whole earth, fwarms with living beings, every plant, every grain and leaf, fupports the life of thoufands. Vegetables feem, at firit fight, to be the parts of organized nature, which are produced in the greateft abundance ; but upon minuter infpeftion we fhall find each fupporting numberlefs minute creatures, who fill up the various gradations of youth, vigour, and old age, in the fpace of a few days exigence. Vegetables are generally produced but once in a feafon ; but among infects, efpecially of the fmaller kinds, a fingle fummer fuffices for fe- veral generations. Thefe therefore would multiply in greater abun- dance than the plants on which they fubfift, but that they are deftroy- ed by other animals, and often by each other ; the fpider feeds on the fly, the birds upon the fpiders, and they, in turn, make the food o£ man and every beaft of prey. Some infects as to their conformation are compofed of feveral rings, joined together by a membrane, which is the ufual form of the body in grubs, worms, and caterpillars. Unlike birds, who traverfe the air with fuch rapidity, thefe humble animals, feemingly lefs favourites of nature, move forward but flowly. The whole body confifis of a fchain of annular mufcles, whofe orbicular fibres being contracted, ren- der one of the rings that was before ample and dilated narrow and long. The fibres of thefe rings are found to be fpiral, as are their motions in a great meafure, fo that by this means they can the better bore their paifage into the earth. Their crawling motion may be explained by a wire wound round a walking cane, which when flipt off, and attempt- ed to be lengthened, has an elaftic contraction of one ring to the other. In like manner the earthworm, having fhot out or extended its body, lays hold upon fome fubftanee with its fmall feet, and fo brings onward the hinder part of its body. Caterpillars have feet both before and behind, which not only enable them to move forward by a fort of tteps made by their fofe and hinder parts, but alfo climb up vegetables, and to ilretch themfelves out from the boughs and ftalks to reach food at a diftance. Behind, their broad palms are befet almofl round with iharp fmall naih, to hold and grafp whatever they!are upon; likewife before, their feet are fharp and hook- ed, by which they can lay hold of leaves, while their hinder parts are brought up thereto. Reptiles that have many feet may be obferved to move them regularly one after another, and from one end of the body to another, in fuch a manner that their legs in walking make a fort of undulation ; and by this means they move much fwifter forward than one would imagine. The motion of fnails is performed in a different manner ; they have a broad fkin along each tide of the belly, which A kAS 2 INTRODUCTION. his an undulating motion, which, with the help of the (lime that covers their bodies, they can move flowly forward, and adhere to every fur- face at pleafure. The fecond fort of infects are flies of various kinds, whofe bodies are covered by fmall plates not unlike our ancient armour, the pieces of ■which are lengthened by unfolding, and fhortened by running over each other. Thefe lead a more luxurious life, transfer themfelves from place to place with rapidity, and fpend their little exiftence in feafiing and propagating their kind. The third fort are ants, fpiders, and others, whofe bodies are divid- ed into two or three portions, joined by a fort of ligament. Of all the race of reptiles thefe feem to be endowed with the greatefl (hare of fa- gacity. The wifdom of the ant, and it's well formed commonwealth, is too well known to be infilled on ; but the fpider, though it leads a folitary and rapacious life, feems endowed with even fuperior inftindts. Its various artifices to enfnare its prey, and, when no longer able to fupply a new web itfelf, the itratagems it lays to get poileilion of that belonging to another, are evidences of its cunning. The minutenefs of infers may render them contemptible in the eyes of the unthinking ; but when we confictar the art and mechanifm in fo minute a ftructure, the fluids circulating in vefiels fo fmall as to efcape the fight, the beauty of their wings and covering, and the manner in which each is adapted for procuring its peculiar pleafures, we lhall find how little difference there is between the great and little things of this life, fince the Maker of ail, has bellowed the fame contrivance in the formation of the elephant and the ant. The ftructure uf the eye in infects is remarkably different from that of other creatures in feveral refpects. It is defended by its own hard- nefs againlt external injuries, and its cornea, or outer coat, is all over divided into lenticular facets, and through the microfcope appears as a beautiful piece of lattice work. Each hole in this is of fuch a nature, that when looked through, every object feems inverted. . This mecha- nifm alone iuppiics the place of the cryftalline humour, which is not to be found in infects. Spiders have generally eight eyes, and flies may be faid to have as many as there are perforations in the cor- nea. Other creatures are obliged to turn their eyes different ways to behold objects, but flies have them fo contrived as to take in every ob- ject: near them at once. In order to keep their eyes clean, they are provided with two antennse, or feelers. Some however are of opinion, that they clean their eyes with their fore legs as well as the feelers; nor is this conjecture ill rounded, when we confider, that in fome forts, par- ticularly the nelh fly, the feelers are too fhort for this purpofe, and therefore their legs alone can fupply the defect. The mechanifm in the feet of rlies, and other infects, defcrves alfo our notice. The amphibious infects, which are obliged to live by land as well as water, have their hindmoit legs made with commodious flat joints, having gviiiles on each fide ferving for oars to fwim with, and placed at the 'extremity of the lirrib; but nearer the body there are two ftifl lupporters to enable them to walk when they have occafion. In thoi'e infects whofe motions are performed by leaping, fuch as the grafs- hopper and cricket, their thighs are ftrong and brawny; thofe, on the contrary, which ufe their claws in perforating the earth, have fuch. parts INTRODUCTION. 3 parts made with ftrength and fliarpnefs, as in the wild bee, and the beetle. There are even fome animals that convey themfelves by me- thods to us unknown. Infefts, which are generated in flagnant waters, are often found in new pits and ponds, and fometimes on the tops of houfes and fteeples. Spiders with their webs have been known tofoar to a confiderable height, having been feen above the higheft (leeple of York Minfler. How thefe animals have been thus capable of conveying them- felves from place to place is a phenomenon for which we are unable to account; fome years ago, it was the method to give reaions for every appearance in nature, but as philofophy grows more mature it becomes more cautious and diffident, nor blufhes in many inftances to avow its ignorance. Thofe infects which are provided with wings have tendons, which diftend and ftrengthen them ; thofe which are provided with four, ufe the outermoft rather as cafes to defend the internal wings than as in- ftruments in flying. When the infect is at reft, the inner wings are generally gathered up in the manner we clofe a fan, nor is it without fome efforts that the little animal can unfold it. Thofe, however, whofe wings are not cafed in this manner, fuch as moths and butter- flies, have them defended with feathers ; for that beautiful variety of colours which we fo much admire, appears, through a microfcope, to be nothing mere than different coloured plumage, as artfully placed as in the wings of birds, but too minute to be difcerned by the naked eye. Such infects as have but two wings have two little balls, or poifers, joined to the body under the hinder part of each wing, that ferve to keep them fteady, and in fome meafure counteracts the changes of the air, which might at every variation carry them in its current : If one of thefe poifers be cut off the infect will foon fall to the ground, but if they are both cut, it will ftill fly, but yet in the direction of every breeze. They are thus formed for motion, rather to provide fuftenance than to avoid danger. As from their natural weaknefs they are the prey of every fuperior order of animals, they feem to find fafety only in their minutenels of retirement ; but even with every precaution they furnilh out a repaft to fwallows and other birds, who, while to us they feem fporting in the air, are then employed in procuring their neceflary fub- fiftance. The infect itfelf, however, is at the fame time in purfuit of fome inferior order of infects, for there are the fame hollilities among the fmalleft that there are amongft the largeft animals. Summer is the feafon of their pleafures ; many of them never live above a fingle feafon, while others are found to continue but one day. Such however as are more long lived, take the. proper precautions to provide for their fafety in winter, and fix upon the moft convenient fituations for fpending that interval, and fuch as want food lay in the proper (lores for fubfiftance. But the greateft number want no fuch neceffary flock, for they fleep during the continuance of the winter. Some caterpillars, for inftance, having fed during the fum- xner retire, at the approach of cold, to a place of fafety, and there, by fpinning a thread like a cobweb, hang themfelves in fome commodi- ous place, covered with a factitious coat, which at once ferves to keep them warm, and guard them from external injuries. Here they con- tinue in this torpid ftate till the returning fun calls them to new life ; A ? they 4 INTRODUCTION. they now expand new wings, and become butterflies, which feem fcaree employed in any other manner than that of reproducing their kinds. Thus we fee among infecls thofe different offices of eating, fleeping, and generation make different feafons in their lives. Were we to com- pare them with other animals, we lhould find, that while thofe purfue fuch pleafures by frequent returns, thefe experience each but once in their lives, and die. There are fome infecls, however, which lay up provifions for the win- ter, of which the bee and the foreign ant are remarkable inftances. The wafp, the hornet, and the wild bee are not lefs afliduous in laying in a proper Rock of food, and fitting up commodious apartments ; but this is wholly for the fake of their young, for they forfake their nefts in winter, leave their young furnifhed with every convenience, and retire themfelves to other places, where, in all probability, they live without eating. In general, all infecls are equally careful for pofterity, and find out proper places wherein to lay their eggs, that, when they are hatched and produce young ones, there may be fufficient food to maintain them ; whether they chufe trees, plants, or animal fubftances, ftill the pafcent creature finds a bed which at once fuppliesfood and protection. The plumb and the pea, each feem to give birth to infecls peculiarly formed for refiding in them. The pear and apple produce a white moth : on the oak leaf are hatched feveral of beautiful colours, white, green, yellow, brown, and variegated. The manner in which thofe infecls lay their eggs is fufficiently curious; they wound the leaf through, and then depofite their eggs in the little cavity. As the infecl increafes, its nidus or bed, increafes alfo, fo that we often fee the leaves of trees with round fwellings on the furface, upon opening of which we may difcover num- berlefs infecls not yet come to maturity. On oak trees thefe nefts ap- pear like little buds, and are in facl only gems, or buds, which are in- creafed in thicknefs when they ought to have been pufhed out in length. The infecl thrufts one or more eggs into the very heart of the gem which begins to be turgid in June, and but for this would have fhot out in July. This egg foon becomes a maggot, that eats itfelf a fmall cell in the midft of the bud, the vegetation of which being thus obftrucled, the fap defigned to nourifh it is diverted to the remaining parts of the bud, which are only fcaly integuments that by this means j>row large, and become a covering to the cafe in which the infecl lies. But not only the oak, but the willow, and fome other trees and plants, have knobs thus formed, which generally grow in or near the rib of the leaf. Among thefe cafes formed by infecls, the aleppo galls may be Teckoned as the moft ufeful, the infecls of which, when come to ma- turity, gnaw their way out, as may be feen by the little holes in every nut. But all thefe are formed by the ichneumon kinds of flies, namely, of thofe kinds which are vulgarly called the blue-bottle fly, Thofe kinds, however, which do not wound the leaf, take great pains to lay their eggs on the furface, in the exacleft and moft curious manner. When thus depofited, they are always faftened thereto with a glue, and conftantly at the fame end. Thofe which lay them in the Waters, place them in beautiful rows, and generally in a fizy fubftance, to prevent their being carried away with the motion of the water. INTRODUCTION. * Upon pofts, and on the fides of windows in country villages, little round eggs have been feen refembling pearls, which produced fmall hairy caterpillars, and thofe like the reft are all laid in very regular order. The gnat, though fo very fmall, is yet very curious in the manner of depofiting her eggs, or fpawn. It lays them on the water, but fixes them to ibme floating fubftance by means of a ftalk, which prevents them from finking. The eggs are contained in a fort of tranfparent jelly, and very neatly laid ; when hatched by the warmth of the feafon, they fink to the bottom, where they become fmall maggots, flick to the ftones, and provide themfelves cafes, or cells, which they creep into or go out of at pleafure, and thus continue till they take the ufual change into that of a fly. Moft of thefe infects are tinged with one principal colour, refembling either that of the leaves on which they fubfift, or the branches to which they fallen ; on thefe they march with great flownefs, and by this artifice are confounded with what they fubfift upon, fo as to efcape the birds, their rapacious and watchful enemies. Such is the manner with thofe infects which being hatched from eggs, are then transformed into caterpillars, which may be called their eating ftate ; after that wrapped round with a covering of their own fabrication, and thus turned into nymphas, which may be called their fleeping ftate ; and laftly furnifhed with wings, and metamor- phofed into butterflies, which is their generating ftate. But there are numberlefs other infects which are brought forth alive, fuch as the fpider, and the fnail produced with a fhell, which grows with its growth, and is never found to forfake it. Thefe are never feen to change, but continue their growth : the fpider, as it becomes older, has its legs longer, and if they be cut off, like thofe of the lobfter they grow out afrefh. The fnail, as it becomes more old, acquires additional ringlets to its fhell, and contains in itfelf both fexes. But there is an animal lately difcovered, whofe powers of generation are ftill more extraordinary than any thing hitherto taken notice of, and from the phe- nomena attending which, Mr Buffon has ventured to affirm, that he ftill believes there may be fuch a thing as equivocal generation. The animal in queftion is called the polypus, a fmall reptile found on aquatic plants, and in muddy ditches. This furprizing creature, though cut into never fo many parts, ftill continues to live in every divifion, and each, in lefs than three days, becomes in every refpect a perfect polypus, like that which was at firft divided. This I think may be juftly eft eemed the loweft of animated beings, and fcarce to be ranked above the fen- fitive plant, except by being endowed with a locomotive faculty, or a power of moving from one leaf to another. It is thus that Nature chufes to mix the kinds of being by imperceptible gradation, fo that it becomes hard to determine where animals end, or vegetables' begin. In this there are evident marks of her wifdom in filling up every chafm in the great fcale of being, fo that no poffible exiftence may be want- ing in her univerfal plan. Were we to afk, why thefe minute crea- tures, in general little regarded by man, except from the prejudice they are of to his labours, where formed in fuch great abundance, it would be no eafy tafk to find a reply. For man's ufe they were not made, as they are allowed to be noxious to him; nor for the fuUenance of other animals that may be of ufe to him, fir.ce the advantages ef the latter cannot \ 6 INTRODUCTION. cannot compenfate for damage done by the former ; perhaps the wifeft anfwer would be, that every creature was formed for itfelf, and each allowed to feize as great a quantity of happinefs from the univ.erfal ftock, as was confident with the univerfal plan ; thus each was formed to make the happinefs of each ; the weak of the ftrong, and the ftrong of the weak, but ftill in proportion to every order, power of conquell and enjoyment. Thus we fhall find, that though man may be reci- procally ufeful to other animals, yet in fome meafure they were formed for his ufe, becaufe he has been endowed with every power of rendering them fubfervient, and enjoying their fubmiffion. NATURAL NATURAL HISTORY OF INSECTS. CHAP. I. Of InfeBs in general. AN Infect is a fmall animal, either compofed of feveral rings joined together by a membrane, or feveral fmall plates, which play one over another, or elfe having a body confiding of two or three parts, joined together by a fort of thread or firing. The firil kind, we commonly call Worms or Grubs ; as alfo, Caterpillars. When they advance from one place to another, they ftretch the muf- culous fkin, which feparates the firft ring from thofe that follow, and thru it it forwards to a certain diltance ; then they contract and wrinkle the fkin on the fame fide, bringing forwards the fecond ring, and fo on ; and thus they can move along without feet, proceed out of the earth, and enter into it again without any danger ; befides, they can proceed in chis manner backward or forward as they pleafe. The fecond fort are flies of various kinds, whofe bodies are an aflemblage of fmall plates, which are lengthened by unfolding, and lhortened by running over each other, much in the fame manner as fome parts of the an- cient armour. The third fort are Ants, Spiders, and many others, whofe bodies are divided into two or three portions, which feem to have but a fmall relation to each other. Their fmallnefs renders them contemptible in the eyes of the gene- rality ; but rather fhould be a reafon for admiring the art and mecha- nifm of their ftructure, which contains fo many veflels, fluids, and mo- tions in creatures fo minute as almoft to efcape the fight ; fuch as mites, and the like. Some of thefe infects are richly adorned, with robes of various colours, fuch as blue, green, red, gold and filver, and many other embellifhments. We need only look upon ihining flies, Cantharides, Butterflies and Caterpillars to be convinced of this truth. The fame wifdom which has given thefe ornaments, has arm- ed them from head to foot, and has enabled them to fight, and to de- fend themfelves ; though they do not always catch what they lie in wait for, or fhun what is hurtful ; yet they are provided with what will belt ferve them for thofe purpoies. Some of them have ftrong teeth, others a double jaw, or a fting, or ftrong claws ; and they have Ihelly armour, that cover the whole body. The mod delicate are furnifhed with hair, which ferves them to break the fnocks they may receive, and to weaken the blows, or to preferve them from the rubs that might hurt them. They S NATURAL HISTORY. They are almoft all very quick in their flight, and getting out of the way of danger ; fome by the help of their wings, and others by the af- fiftance of threads, which they can throw out, and hang by them under the leaves of trees, on which they live. Others again can leap to a great diftance, and fo get out of harm's way. It is alfo wonderful to confider the various organs by which they are afTifted to live, and the inftruments they make ufe of each according to their profeffion. Some are fltilful in fpinning, having two diftaffs and fingers to draw out the thread ; others can make nets and webs, and are provided with thread and fhuttles. Some again build them- felves houfes with wood, and have the fickles to cut it ; others are fkil- ful in making way, and have fcrapers, fpoons, and trowels. They have generally a trunk, whofe ufes are more wonderful than that of the elephant ; for with it they can extract liquor with more (kill than any man. Some have tongues, which ferve them for tafting, and others have a fort of gimblet to bore holes with. Others have piercers fixed to their tails, by means of which, they make lodgings for themfelres and families, in the heart of fruits, under the bark of trees, and even in the hardeft wood. Mod of them have excellent eyes ; befides which, they have horns or feelers, to prevent their meeting with any tiling that may do them harm, efpecially in the dark. Some of thefe horns are full of knots, or joints, like thofe on the heads of Cray-fifh ; and feveral are terminated like a comb. Others again have four large wings, equal to the length of their bodies, and fome have them fo fine, that the leaft obftacle will tear them in pieces ; but thefe are generally hid under two ftrong fhells, which may be raifed up, or (hut clofe down, which they always are, when they are at reft or creep. Befides thefe, there are other great varieties, which will be taken notice of in their proper places. All forts of infefts are generated like larger animals, from eggs ; and thefe at firft are enclofed in a fingle or double covering, which opens when the animal is old enough to pierce through. When the brood break the covering, at their coming into the world, thefe crea- tures are faid to be viviparous ; as for inftance, Millipedes, or Hog- lice. When the old ones bring forth the young in a covering, where they are to remain fome time, they are faid to be Oviparous. All thefe in- fects, and indeed, all forts of animals are brought into the world one of thefe ways ; and thofe of the oviparous kind, always lay their eggs in a proper place, where they are hatched by a certain degree of heat* It was formerly the common opinion, that all forts of infects pro- ceeded from corruption ; but this has been exploded long ago, efpeci- ally fince the invention of Microfcopes. And indeed, it would be ab- furd to fuppofe, that thefe animals which are perfect in their kind> fhould be the effect of chance. The motions of thefe creatures, may feem to us without any defign ; and yet, it is certain that they tend to a certain end, even thofe of the fmalleft, as well as the largeft. No infect abandons its eggs to chance ; for they are never miftaken in lay- ing them in places, where they may receive proper nourifhment, as foon as they are hatched. In thofe countries where Silk Worms natu- rally live, you will always find their eggs ou a mulberry-tree, and no where elfe, which plainly fhews they know what they are about. The Caterpillars that feed upon cabbages, are never found upon willows, - NATURAL HISTORY. 9 hor thofe of willow upon cabbages. The moths delights to be among curtains, woollen (tuffs, or papers, but never upon plants, nor in mud, nor yet in corrupted aliments ; and yet the contrary happens to flies, who lay their eggs in flefh ; and therefore, it is plain, it is inftincl, and riot chance that directs their choice. That this does not arife from the corruption of the flefh is plain, from the following experiment ; take a bit of beef frefh killed, and put it into an open vetfel, another into a clean one covered over with a piece of filk, fo thin as to let in the air, and yet thick enough to hinder the eggs of the the from paffing through it, and you will find the firft bit produce maggots as ufual, whereas the fecond will be entirely without ; however, the flies being attracled by the fmell, will come in crowds to the covering, and endeavour to enter in, and perhaps lay fome of their eggs upon the filk, but they will penetrate no farther; from whence it is plain, that corruption pro- duces nothing. When fome of thefe eggs are hatched, the young will appear in their perfect form, which they never change afterwards. Thus, fnails come into the world with their houfes on their backs, and continue always in the fame fhape, as well as that of the houfes ; for they grow in pro- portion to the animal itfelf. Such likewife are Spiders, which proceed from their eggs completely formed, and change nothing afterwards but their fizes. But the greateft part of other infects pafs through dif- ferent ftates, and aiTume fucceffively the figure of two or three animals which have no refemblance to each other. Many infects when they proceed from their eggs, appear to be nothing elfe but a fort of worms, fome without feet and others with ; thofe without feet are under the care of their dams, which fupply them with food, if they are not hatched in a place where they find nourifiiment. Thofe with feet, go of their own accord to fearch for food on the leaves of the tree, that is molt fuitable to their nature, which is the very fame where the dams laid their eggs. Thefe grow fenlible in a fhort time, and fome of them throw off their old covering five or fix times, and feem to grow young again, by having a new fkin. Thefe all pais through the middle Itate, which is that of a Nymph or Chryfalis ; but this wants explanation. The Caterpillar firft leaves off feeding, and inclofes itfelf in a fort of coffin, which is different in the different kinds. This covering preferves them from external injuries, till they acquire a new form. Thefe have the name of Nymphs, and then they aiiume all the beautiful colours which adorn the various kinds. Some then call it an Aurelia, or Golden Nymph, becaufe the covering which is more or lefs ha'd, affuir.es a colour as fhining as gold. Some call this covering a Cod, especially when it is applied to a Silk Worm. The laft (fate or metamorphofis, is when they arife oat of their cof- fin, and become flying infects ; for that which was a worm before is deftroyed, or rather turns into a fly. There are fome infects that live only upon greens, and others that feed on nothing but wood. It is iiow generally believed, that there is another fort which are nourifhed even in (tones themfelves ; however, it is more certain, that there are many which never appear out of the water. There are reckoned no lefs than three hundred kinds of Caterpillars which are already known, and the curious are (till making new difcoveries : their fhape, their co- lour,, their inclinations, and their manner of living, diftinguithes th« *9 NATURAL HISTORY. feveral forts from each other; and yet they are all perfect in their kind. However they are all compofed of feveral rings, which being either extended or contracted, enable them to carry their bodies where ever they have occafion to go. They have a certain number of feet with joints, and arc armed with hooks, wherewith they fix themfelves to the barks of trees, efpecially when they fieep, which is the time they pais from one ftate to the other. They have almoft all threads com- pofed of a fluid gummy matter, which they get out of the leaves that fupply them with food. When they perceive any danger of being car- ried off by birds, or crulhed by the motions of the branches, they fix themfelves to the trees by means of this gum, which is made into threads by feveral openings of their bodies, which threads they unite with their paws, and form feveral into one, capable of fupporting their own weight, and lo are generally fecure from danger. Some natura- lifts believe, that the colour of the Caterpillars h one of the belt, pre- fervatives againlt the birds that are fond of feeding upon them; for they generally are- of the fame principal colour as the leaves whereon they teed, or of the fmall branches to which they are fixed, when they undergo the metarnorphofis ; thus, thofe that are nourilhed on the buckthorn-tree are as green as the leaves thereof, and thole that live upon apple-trees and bulhes are of the fame colour as the bark ol thofe plants. Even the fmalieft of thofe animals have methods of fcreening themfelves from the purfuit of the birds ; for they may be often found under the leaves and not above, where they would be more expofed. All forts of Caterpillars ufe a particular kind of nourilhment, which they never change upon any account whatever ; for though they live npon greens, each has its ov/n plant, and will fooner die than feed up- on any other, unlefs they are nearly of the fame. Towards the end of the fummer, when Caterpillars have fufficiently fed on the green leaves,, then they leave oif eating, and fecure a retreat, where they undergo the fucceeding changes. A few days are fufficient for fome to undergo this metamorphofis, while others continue months, and even years in their coffins. Some at this time hide themfelves in the ground, and others get upon the roofs of houfes, in the holes of walls, under the bark of trees, and even into the heart of the wood ; others again, wrap themfelves up in threads and gum, and rowling themfelves in the fand, make themfelves a fort of ftone coffins. Likewife, fome reduce little bits of wood to powder, and with their gum make a covering in which they wrap themfelves ; and when it is quite formed, it is not much un; like an Egyptian mummy. Some forts of Caterpillars are capable of fpinning threads, in wbkh- they are covered and defended from the rain, particularly Silk-worms, of which more hereafter. The moft common fort of Caterpillars are thofe that we meet with on elms, apple-trees, and bufhes; and the But- terflies that proceed from them, fix upon fome entire leaf, where they lay their eggs in the autumn, and die foon after ; but befor; winter they are hatched and become fmall Caterpillars, which with their threads make themielves beds and fpacious lodgings, where they lie during the cold feaibn, diftribuied as it were in different rooms with- out eating, "or coming out.

Thus, having given fome account of infects in general, we ihall now proceed to par- ticulars. CHAP. IL OF INSECTS OF THE BEETLE KIND. THE Beetle is a flying infect, with a cafe over its wings to defend them from danger when it does not fly; though fome would have thefe cafes a different fort of wings, and therefore place them among four winged infects but -very improperly ; for they feem to be defigned by nature to preferve their wings from hard bodies, which they often meet with when they dig holes in the ground, or gnaw rotten wood with their teeth, to make themfelves honies or nefts. When they fly they rill the air with a humming noife, and perhaps greater than that of any other infect* They have a great averfion to rofes, whofe frnell they cannot bear, and fome affirm it will kill them. They are natu- rally fond of ivy, and delight to get under its leaves. There are differ- ent forts of Beetles, fome being large with horns, and others fniall with none, from which they have different names. The Elephant Beetle is the largeft of this kind hitherto known, and is found in South- America^ particularly Guiana and Surinam, as well as about the river Oroonoko. It is of a black colour, and the whole body is covered with a very hard fhell, full as thick and as firong as that of a fmall crab. Its length from the hinder part to the eyes is almoll four inches, and from the fame part to the end of the probofcis or trunk four inches and three quarters. The tranfverfe diameter of the body is two inches and a quarter, and the breadth of each elytron or cafe for the wings is an inch and three tenths. The antennae horns or feelers are quite horny, for which reafon the probofcis or trunk is move- able at its infertion into the head, and feems to fupply the place of feelers. The horns are eight tenths of an inch long, and terminate in points. The probofcis is an inch and a quarter long, and turns up- wards, making a crooked line terminating in two horns, each of which is near a quarter of an inch long ; but they are not perforated at the end like the probofcis of other infects. About four tenths of an inch above the head on that fide next the body is a prominence or fmall horn, which if the reft of the trunk were away, would caufe this part to refemble the horn of a Rhinoceros. There is indeed a Beetle fo called ; but then the horn or trunk has no fork at the end, though the lower horn refembles this. The feet are all forked at the end, but not like lobfters claws. The Rhinoceros Beetle, of this there are feveral kinds, one of which was brought from the Eaft-Indies, and is of a jet-black colour, and has a horn growing on its nofe which turns upwards ; and about the mid- dle of the belly there is another horn, which arifcs from a tubercle and turns inwards. The whole body, from the end of the horn to the back part, is four inches long, and the breadth is almoft two. It has alfo B 2 two ai NATURAL HISTORY. two horns on the head behind the fnout, and there are fix feet or forked at the ends. This has been juft taken notice of, and differs chiefly from the Elephant- Beetle, in not having the horn on the fnout forked at the end ; befides which it has no horn on the belly. There js alfo another Rhinoceros-Beetle, which is common about Vienna in Germany. The horn has a greater refemblance to that of a Rhinoceros, for it turns up like it, and is fharp at the end, and behind the head it has a prominent bump, and there are fix feet as in the former. It is all over as black as pitch, except the belly, which is of a deep red. The horn of the nofe is fo very fharp, that it feems to be whetted to a point. The third and fourth kinds are much of the fame fhapes, only the wings of the former are longer than the cafes, and in thefe they are fhorter. They look as if they were covered over with fhining- ink, and the horns on the head are full of knots. The head is of a greenifti gold-colour, and the fhoulders are red ; but the belly is pur- ple, and the cafes of the wings are of the fame colour as the head. The feet and legs are of a dun- colour, and the wings under the cafes are whitifh. The Stag-Beeile is of a dufky- brown colour on the back, or rather blackifh, especially about the cafes of the wings and breaft. It is above an inch long, and about half an inch broad, and it has two horns with^ out joints, but blanched like thofe of a Stag, whence it has its name. When this Beetle is full grown they are as long as a man's little finger, and there are nippers at the end with which this animal can pinch or lay hold of any thing, they being not unlike lobfter claws. The eyes are hard, prominent and whitifh, and near them on both fides there are feelers, one pair of which are branched, and placed between the horns and the eyes, having each a joint which makes almoft a right angle. The other pair are placed in the middle of the forehead and are ftrait and flat, having each a tubercle like the head of a nail at the end, whence by fome they are faid to be clavated. It has fix feet, of which the foremoft pair are longer and greater than the reft. The horns are fometimes as red as coral, which give this Beetle a very beautiful ap- pearance ; and the eggs when they are hatched turn into worms with fix feet, which are afterwards changed into Beetles. It is very com- mon in Kent and Su/ftx, and is fometimes feen in other parts of England. The Beetle withlunated, prominent, denated jaws, and a fmooth breaft, is of the larger kind, being an inch long, and two thirds of an inch broad. The thorax is fmooth, convex and black, without any prominences, though it has a fort of an edge. The cafes of the wings are fmooth and of a blackifh purple colour. The jaws are in the fhape of a half- moon, and are prominent and black, having two teeth in each. It is found in hedges where there are afh trees, for it feeds on the rotten part of their trunks, and burrows in the earth under their roots. The Brafs Beetle, is of the larger kind, and has a fhort broad breaft, the fhape in general being confiderably broad in proportion to its length j but the eyes are fmall, and the legs long and flender. The whole bo- dy and outer part of the cafes of the wings are of a fine fhining green, with a mixture of yellow. It is fometimes met with in oui gardens. The Beetle with clavated feelers, and the cafes of the wings on the fore part. It is of the fmall kind, and of an oblong fhape, with a black; head and breaft. The cafes of the wings are grey towards the top, but elfewhere NATURAL HISTORY. ij tlfewhere the colour is of a dufky blackifh brown, with a tranfverfe ftieak of white. This is common about the carcailes of dead animals, particularly birds Some would not have this to be properly a Beetle, but call it Dermeftes. The Black Dermejles with a white fpot on each of the cafes of the wings, is of the fmall kind, and has a body of an oval ihape, which is black as well as its legs and feelers; on each of the cafes of the wings there is a remarkable white fpot, with five others fo fmall that they are hardly vinble. This animal when touched, or terrified with a noife, will flop and draw its head and legs undei the fhell of the body. It is common about lbme houfes and old walls, and more particularly in places where victuals are kept The Dermeflts* of a cylindrical fhape, with a thick hairy neck, and teftaceous cales for the wings. This is alfo of the fmall kind, and the body is of the (nape of a cylinder, with a thick roundifh black hairy neck. The cafes of the wings are longifh, blunt at the point, and like fhells with a black edge or margin running all round them ; but the colour of the cafes themfelves are of a whitilh brown, and the body and legs are black. The antennae or feelers are reddifh. The fize is not much bigger than a large loule, and when it is touched or terrified it con- trails itfell and lies quite ftill. It is very common in houfes. The feelers of theie three forts are of a clavated fhape, and are perforated traniverfely. There is another fort of infects of the Beetle kind, with (lender feelers like threads, though a little thicker near the ends. This fort, as well as the former, are by lbme of our belt authors placed a- mong the Beetles. The Green Tortoife Beetle with clavated feelers divided into rings, has a very fmall oval body, convex on the back and flat on the belly. The upper part confifts of the cafes of the wings and the fhield, which are both green and fmooth, and appear to be one fingle cruft, divided only by a kind of triangular future. The belly is black, and the head is entirely hid under the fhield. The feelers are pale, only they are of a deeper colour on the top than elfewhere. The legs are of a pale brown, and there is a fort of a prominent rim running round the cafes of the wings, which entirely cover the body. It is common in gardens, and may be met with on mint and other herbs. Thefe fort of Beetles are by Linn&us called Caffida, from the fhield. The Black Cajfida, or Shield Beetle with feelers like briftles, and a roundifh body, is a very fmall Beetle, of a little longiih fhape, and of a dufky black colour. The cafes of the wings are oblong, and lightly (freaked with feveral very fmall hollowifh fpots. The fhield is round- ifh, being fomewhat broader than long, and it is rough on the upper parr, with a cruciated prominent edge. Sometimes there are two (pots on the fide towards the hinder part, with yellow hairs thereon. The belly is black, but in fome lights has a glofs of filver colour. It is met with in houfes in the country, where it often does a great deal of riiifchief, eating holes in woolen cloths and ftuffs. When it is touch- ed ever fo lightly it draws up its head and wings under its body. The over pale-clouded Cajjlda, or Shield Beetle, with an undivided fhield that covers the head. It is a very fmall Beetle, and has a body of an oval ihape and of a pale brown colour, fpotted and clouded all pyer with one that is more dufky, which makes it look fomewhat like the «+ NATURAL HISTORY. the ftiell of a tortoife. The fhield is in the fliape of a half-moon, an* of a pale colour without fpots ; but the cafes of the wings are ftreaked and fpcckled, and the ftreaks run in crooked lines. The body is black» and the feelers are black and {lender. It may be eafily found in beds of baum, or mint. The Lady-Cuiv with reddifh cafes for their wings, and feven black fpots thereon, is an infect well known even to children, and has a black head with two white fpots on the forehead, and a black breaft, which is whitifh near the edges. The cafes of the wings are of an orange- colour, and there are three black fpots towards the bafe of each, and one that is common to both, which with the former makes feven in all. The feelers are very fmall and clavated; and the under part of this in- fed is black. The Lady-Cow with red cafes for the wings, and two black fpots thereon, that is one on each. The breaft is black, only there is one large white fpot on its fide, and two very fmall ones near the bafe ; as alfo two others of the fame fize at the infertions of the feelers. The belly and legs are black, as are the feelers likewife ; and it is common to be met with on alder and other trees, as the former is among hedges in the Summer time. The Lady-Conu with black cafes for the wings, with four red fpots thereon, that is two on each cafe. The breaft, is entirely black, and the fpots on the cafes of the wings are of a blood-red colour ; but that which is neareft the breaft on each is largeft. They are met with on maple trees in the North parts of England, and are fometimes feen, though but feldom, in the hedges near London. The Chryfomela is of the Beetle kind, and the feelers are in the fhapc of necklaces of beads, but thickeft towards the extremities. The body is nearly of an oval fhape, and the breaft is oblong and roundifh. I. The blew-green Chryfomela is one of the largeft fort of this kind, though they are all but fmall. The head is little, the legs flender, and the belly fmooth. The back is roundifti or convex, and the colour is a mixture of blue and green, with a very fine tincture of gold colour diffufed throughout. The edges of the cafes of the wings are a little prominent, and they are marked with a few hollo with fmall fpots all the way round. The feelers, legs and belly are entirely green. It is common in the meadows in May and June. 2. The Chryfomela with a breaft and the cafes of the wings of a red colour, is fmaller than the former, and not fo convex on the back. The head is fmall and black, as well as the body, legs, lower part of the breaft and feelers ; but the upper part of the breaft is red, as are alfo the cafes of the wings. It is commonly met with on fome fort of willow trees in June and July. 3. The blue- green Chryfomela with a red breaft and thighs, is of the fmall kind, and the head and cafes of the wings are of a beautiful ihining green with a blueifh caft. There are a few hollow fpots on the head, and the breaft is fmall, convex, and of a reddifh colour, with a caft of blue-green. The upper part of the legs is reddifh and the other black as well as the feelers. It is common in moft parts of this kindom. 4. The black Chryfomela with hollowed points, is one of the largeft £>f the kind, and is all over black, and the breaft and cafes of the wings arc NATURAL HISTORY. t$ are marked with fmall hollow points very near each other. The wing* are flexible, foft, and blunt, and the feelers confift of twelve joints. They creep but flowly, an 4 are found in quarries. 5. The black fmooth Chryfomela with the bafe of the feelers yellowifh. It is of a middle fize, and the joints of its wings are neither hollow/ nor ftreaked, but the black colour of this infedt has a blueifh caft. 6. The purplilh black Chryfomela with hollow ftreaked points, is found upon the birch tree, and feeds upon its leaves. This infect is of a blackifh blue inclining to purple, and it is rather of a violet colourr but the belly feet and feelers are black, and the head and bread are marked with very fmall hollow points without order. The cafes of the wings are ftreaked, and the eyes are hardly to be perceived. 7. The purplifh black Chryfomela fprinkled with hollow points, is found? in the Spring feafon on the alder tree. It is like the former, only it is larger, and the cafes of the wings are marked with hollow points,, difperfed here and there, but not ftreaked. 8. The purplifh black Chryfomela with the breaft yellow on each fide, is found upon the willow tree, and is of the fize and fhape of the for- mer j as alio entirely of the fame colour, only the breaft is red on the fides, round in the middle, and of a violet-colour ; but a little blacker on the cenrer. The head and lower belly are black, and there is a black point in the middle of the red that is on the fides of the breaft. 9. The green Alining Chryfomela with a fmooth breaft, and the cafes of the wings marked with hollow points. This is alfo found upon the willow, and is of a bright green colour. It is marked with hollow points that touch each other, and it is blunt towards the vent. It feems to open the cafes of the wings with trouble, and the breaft is fmooth behind but a little marked with points, and the feelers and feet are black. 10. The green fhining Chryfomela with the breaft hollow before. It has not the breaft equally hollowed, but only at the top. 1 1. The green ihining Chryfomela with a level breaft, is lefs than the former, but rounder. 12. The Chryfomela that is a little teftaceous, is found in the begin- ning of the Spring among rotten wood, and is placed by authors- among the largeft kind. The colour of the whole body, which, is oval, is cheihut, but the eyes are black, and the feelers and the feet red. The under parts of the feet are white, and the cafes of the wings are marked with hollow points. 13. The pale green Chryfomela is found upon willow trees, and re- fembles the former, only it is a little fmaller ; but what diftinguifhes this from that is the pale colour, and the nine rows of points on each cafes of the wings, placed long ways. The eyes are black and the bot- tom of the feet white. 14. The Red Chryfomela with a cylindraceous breaft, is found upon the flower de luce. It is of a middle fize, and its breaft, cafes of the wings, and the top of the head are red ; but the feelers, eyes, knees, belly, breaft plate, and under part of the head are black. The breaft is- much narrower than the cafes of the wings, and is hollow on each fide. The cafes of the wings are marked with hollow points of a middle iize. 15, Ths i6 NATURAL HISTORY. 15. The Copper coloured Chryfomela is very common on willows^ and is of a middle fize. It is of the colour of red copper that has been poliflied. 16.

It is one of thelargeft fort, and its red wings are marked with fmall points, and the extremity of each cafe of the wings has a black fpot, and the bread is fmooth and of a green and black colour, as well as the corfet, belly, and feet ; but the feelers are black. The cafes of the wings of this kind are not plates or leaves, but feem to be made up of eleven joints, of which the lad is largeft. It throws out an oily fluid when touched, and Rinks fo abominably, that few are able to bear it. 17. The Chryfomela with a red cylindraceous bread, and red cafes for the wings, is found on the branches of afparagus, and devours the dalks. It is but fmall, and has a head of a '.lackifh blue, with black feelers, and the bread narrow and cylindric, marked behind with two black points. The cafes of the wings are oblong, yellow, and of a fallow colour on the external edge ; there is alfo a blue fpot like a crofs on the cafes of the wings. 18. The Chryfomela with a green bread, and red cafes of the wings, marked with a blue crofs. For fhape it is much like that of the poplar tree, and the colour of the head and bread is that of green copper, with black feelers, and the feet are generally black. The head, bread, and cafes of the wings, are of a fingular beauty, and painted with copper-coloured dreaks, a little inclining to blue. 19. The oblong black Chryfomela with red cafes of the wings marked with four black fpots, is very larged of this kind, and is of a rounder ihape. There are two large fpots on each cafe of the wings, the tird ef which is oval, but the other more fhort. The feelers are almod dentated, and the bread is fhort. 20. The red Chryfomela with each cafes of the wings marked with five black fpots. It is found upon willow trees, and is one of the larged of this kind, having a black head with a red bread, black in the middle, and red cafes of the wings, upon each of which there are five large black fpots of an unequal lize. The belly and the under part of the feet are black. 21. The long dufky Chryfomela with the letter S marked on the cafes •f the wings. The breaft is grey with white hair, and the cafes of the wings are of a greyifh-brown, with a white fpot of the fize of a grain of caraway-feed, of the fhape as above. 22.

There is on the latteral edge of the breaft in the middle of eacli cafe of the wing, and on the . external edge, a long line of yellow colour ; the legs and the internal part of the thighs are alio of a yellow colour, and the feelers are knotted* 27. The Cbryfomela with a black breaft, and red cafes of the wings marked with a black fpot. It is of a middle fize, and has a narrow- oblong body, with the feelers, head, breaft and belly black ; but the wings are white, and the feelers fmaller than in other kinds ; the cafes of the wings are of a bright red, furnithed with eight ftreaks or upwards* confuting of hollow points ; and the bafe on the points are black. 28. The blueilh-green Cbryfomela with a red breaft and thighs, makes its neft in the galls of the willow tree. The head and cafes of the wings are mining, and of a blueilh green, marked with hollow points. The breaft is fmall, marked with a reddiih green or reddifli chefnut colour, and it is thick and convex* The feelers and the bottom of the feet are black. 29. The Cbryfomela of a yellowifh fhell colour, with fhort wings, is met with among flowers, and is of the fize of a loufe, with an oblong fmooth body. The feelers are full of knots; but the cafes of the wings are furrowed, and fhorter than the two joints of the belly. 30. The teftaceous oblong Cbryfomela with accumulated cafes of the wings, is found on trees, and is the leaft infeft of this kind. It is of a chefnut colour, with the feelers like threads, and pointed cafes of the wings which cover the tail. 31. The dufky Cbryfomela with a blackifh head, is found on the windows in the fpring, and is fomewhat lefs than a flea. The body is oblong, and the feet are of a paler colour than the body, which is of n black chefnut colour, with a black head. 32. The Cbryfomela with dufky cafes of the wings, and a yellow edge, is of a middle fize, with a brown head. The breaft is yellowifh, and the cafes of the wings almoft black j but the feet are yellow, and the feelers alternately black and yellow. The wings are brown with black veins, and the belly yellow marked with a broad black line. The Curculio or IVeevel, is a fmall infect not unlike a bug, which is found among corn, wherewith it is nourifhed, and it eats all the in- fide, but leaves the bran behind. But there are different kinds of thefe, which feed in a different manner, of which the following are mentioned by Linnzus. 1. The brown oblong IVeevel with ftrait and fharp cafes of the wings, is the largeft of thofe that are found in Sweden. The cafes of the wings are not fo large as in other infecls of the fame kind ; but the feelers are big, and have the laft joint of a red colour, and very long. 2. The dufky Weevel with ftreaked cafes of the wings, and as hard as fhells. Linnsus comprehends under this fpecies the Dufky Weevel with fhelly cafes of the wings, and marked with two ftreaks. The greater Beetle, with rough cafes of the wings, of a greenilh afh-colour, and variegated with black. The black Norway Weevel, variegated with yellowifh fignatures. He fays there are feveral forts of the fecond kind in the fields of Sweden. It creeps flovvly, and ftieks faft to any C £hin£ vS NATURAL HISTORY. thing it touches. When it is taken it endeavours to pinch the Ifelrjfr and is found upon thittles. It is of a blackifh grey, and has the body„> mouth, breaft, cafes of the wings and legs, marked with ipecks near each other, which are all hollow. This infect gets among the leaves^, where it changes, and becomes a winged Weevel. 3. The Grey Weevel with an iron-grey mark on the cafes of the wingsr and is found upon willows, being like the former. It is grey and white, with black feelers, and jaws almoft as long as the breaft. The end of the breaft is white, and there is a fpot of a tawny colour, on the middle of each cafe of the wings. 4. The Weevel variegated with black and white, and with a plain carinated trunk of the length of the breaft. Frifch calls it the Weevel with a fliort fnout. This infect is of the fhape of the former, and the colour is b!ack and white. 5. The Weevel of a dufky brafs colour, with a fhort fnout and breafL It is called in the Transactions of Upfal, the accumulated Weevel, of a longifh fhape and of a dufky brafs colour. This infect is very com- mon in Sweden, the f am ale is larger by half than the male. 6. The Weevel with a fhort fnout and breaft, and marked on the breaft with three pale ftreaks. It is common in the gardens and mea- dows, and is twice as large as a loufe. The body is grey, but the feelers are reddifh. 7. The Black Weevel with a trunk or fnout the length of the bread*.

The Afh-coloured oblong Weevel with red feet, is like the former in fhape, fize, and colour, and might be taken for the fame, if the thighs, legs and feet, were not of a yellowifh red colour ; befides it has no down. Linnaus takes it to be the female of the former. 10. The Grey Weevel clouded with black, is of a longifh fhape, and the feet and feelers cf a dufky colour. This is to be met with among forrel, where it makes its neft, and afterwards is metamorphofed into a* winged Weevel. It eats the leaves of forrel on the under fide. 1 1.

The roundifii Weevel, clouded with brown, and a white fpot in the fhape of a heart on the middle of the back. In the tranfaftions of Upfal it is called the lead aih coloured roundifh blunt Weevel; and it is found on the fame plant as the former, and is of Che fize of a muf- tard feed. 18. The oblong Weevel with a reddifh fhell, and the bread almod as long as the cafes of the wings. Mr Ray calk it the fmall dirty-brown Beetle, with a long trunk bending downwards. It is found upon fc- veral forts of feeds, on which it lives, and is of the fize of a loufe, 19* The pitchy Beetle with an oval belly, is very common in Sweden, which is all that Linn&us fays of it. 20. The Corn Weevel is fhaped like a bug, and feeds upon corn. This is the fird that was fpoken of. 21. The black Weevel with longifti opaque cafes of the wings, is twice the fize of a flea, and is of a black colour. The cafes of the ■wings are dreaked, and marked with opaque points. 22. The black Wtevel with fhining cafes of the wings, is lefs by one half than a flea, of a black colour, and the cafes of the wings flreaked, fhining, and marked with points. It is four times lefs than the for- mer, and the cafes of the wings and belly are of an oval fhape. 23. The black Weevel with the cafes of the wings of a blackifh blue, is found in hedges, and is of the fize of a flea. The head, bread, and feet are black, marked with fmall hollow points, and the cafes of the wings are of a violet- colour, or of a blackifh-blue. 24. The blackifh-blue Weevel is found in hedges like the former, and is of the fize of a flea. The head, bread and thighs, are of a blackifli- blue ; but the cafes of the wings are of a deep blue. 25. The black Weevel with whitifh thighs, is very like the former in fhape and fize.; but the cafes of the wings are black and dreaked ; and generally the legs are pale, with black feelers. The head and bread are marked with hollow points. 26. The aih coloured Weevel with a black fpot on the cafes of thi». wings, and legs of a paleifh yellow, is found on the leaves of willow. It is no bigger than a loufe, and the head and jaws are black without hair; the bread is alfo black, and covered with afh-coloured hair. The cafes of the wings are black, dreaked and covered with the like hair, and in the middle of each wing there is a black fpot. The feelers are of the fame colour as the legs. 27. The afh-coloured Weevel with red legs, is common in dry grounds, and is of the fize of a flea. The colour is aih, and the cafes of the wings dreaked, with reddifh feet. 28. The Afh-coloured Wee vel with longitudinal dreaks of a lighter colour, is found among the fand. It is larger than a loufe, and is of ,an afti-colour all over. The eyes are black, the feelers afn-coioured, C 2 ani 20 NATURAL HISTORY. and there are feveral lines ; one upon the back, of a bright afh-colour> and another upon the wings of a light afh-colour. 29. The livid Weevel with the cafes of the wings fpotted with four dark fpots. It is found upon the leaves of the alder-tree, and is a leap- ing infect of the fize of a loufe. 30. The blood-coloured Weevel is found in corn, and is much of the fize of a loufe. 31. The black Weevel with the cafes of the wings red in the middle, is found among flowers, and is of the fize of a flea. 32. The black Weevel with red cafes of the wings, and alongifh hin- der part of the head ; differs very much from the former kinds ; for the head is black, and looks like that of a fox deprived of hair. The jaws are fhort, the feelers black, and the wings of a deep red, but fireaked and marked with hollow points. 33. The black Weevel with black cafes of the wings, and a double white ftreak at the bafe, which is red, is very common every where. It has a black head funk into the bread, which is red without hair, and the body is fhort and without a trunk. The Flying -Beetle of the Wefllndies, called by the natives Acud'iay is a fhining infect, and is almoft as big as a Wren. There are four fhining fpots like ftars, two of which are near the eyes, and two under the wings. Some pretend, the natives, before the coming of the .Spa- niards, made ufe of thefe Beetles inftead of candles. There is an infect of the Beetle kind, known in England hj the name of a May Bug, and in fome places a Dorr. It has two pair of wings» one of which may properly be called the cafes, and the other the real wings. The cafes are hard, and of a reddifh brown, fprinkled with a whitifh duft, which eafily comes off. The legs and tail are whitifh, but the reft of the body is brown, except a white and dentated line wherewith each joint is marked on both fides the belly. It is thought that the females make holes in the earth with their tails for the fake of propagation ; but it is uncertain whether they lay eggs or fmall worms. But be that as it will, thefe worms are prejudicial to the roots of corn and young plants ; and they are fometimes fo numerous, as to do pro- digious mifchief ; they continue io long in this ftate, that they are the more dangerous on that account ; and it is faid the hardeft froft will "not hurt them. Rooks and hogs are very fond of thefe worms, and devour vaft numbers of them ; hence the advantage of rockeries is very- evident, as the inhabitants of the county of Norfolk have found to their coft ; for they lately took it in their heads to deflroy them all, fince which time they have been peftered with great numbers of thefe worms, which have deftroyed the roots of the wheat to their very great damage. One farm in particular was fo injured by them in the year 1750 and 175 i, that the occupier was not able to pay his rent, which the land- lord was not only content to lofe, but like wife gave him money for the fupport of his family. Thefe May-bugs are feen mod frequently flying about in the evening ; for in the day time they hide themfelves in the leaves of feveral trees till fun-fet, when they appear in great numbers, and often fly in the faces of paffengers. Moufet informs us, that in 1574 there fell fuch a great number of thefe infects into the Severr, that they ft opt the. v, heels of the water* NATURAL HISTORY. 2t mills. This was on the 27th of February ; but the larger fort do not appear till May. In Ireland they fuffered fo much by thefe infefts, that they refolved to fet fire to a wood of ibme miles extent, to prevent their communication with others at fome diftance. And indeed it is certain, that where there are few trees and many rooks, the inhabitants are leaft infefted with them. In fome years their necks are covered with a red plate, and in others with one that is black ; but thefe are diftincl forts ; and fome have obferved that they do not appear in the fame year, but alternately. Rafei has been ft curious as to catch fome of thefe infedts and put them under glaifes, where they laid great numbers of eggs ; from whence it is plain that they do not bring forth their young alive, which was doubted of before. They foon change to worms of a white colour, and at laft increafe to a considerable bulk, and he kept them two years in this ftate, and fome three, without any change, excepting their be- coming larger. At this time they were an inch and a half long, and of a yellowifii white colour. Their body confifts of twelve fegments or joints, as thofe of caterpillars, without including the head. On each fide the body there is a protuberance that runs all along the fegments ; in ic there are nine holes, through which this worm is fup- pofed to breathe. Under the three firft there are fix feet, of a reddifti- brown, compofed of four or five joints, and they are all alike hairy, and of the colour of the feet. The head is large in proportion to the body, and of a brownifh fhining yellow, with a pincher or nipper placed before, of a deep brown, and blunt, but dentated at the end ; between thefe there is a fort of femicircular lip, and by the help thereof, this infeft cuts the roots of plants and fucks out their moifture. There is no appearance of eyes, but behind the nipper there is a feeler, confid- ing of five joints, and of a brownifh- yellow colour. This woi m changes its Ikin once every year, and towards the end of the fourth year becomes a May Bug. The American ball Beetle, called by the inhabitants Tumble-dung, is the moft numerous and remarkable of the Beetle-kind of any in North-America. Their employment is to find nefts for their eggs. They are endowed with fagacity to difcover fubfiftence by their excel- lent fmelling, which direfls them in flights to excrements juft fallen from man or beaft, on which they inftantly drop, and fall unanimoufly to work in forming round balls or pellets thereof, in the middle of which they lay an egg. Thefe pellets in September, they convey three feet deep in the eanh where they lye till the approach of fpring, when the eggs are hatched and burft their nefts, and the infe&s find their way out of the earth. They affift each other with indefatigable induf- try in rolling thefe globular balls or pellets to the place where they are to be buried. This they are to perform with the breech foremoft , by raifing up their hinder part, and lhoving along the ball with their hind feet. This infed is all over of a dufky black, and has fix legs, two of which are joined to the breaft and four to the belly. They are always accompanied with other Beetles of a larger fize, and of a more elegant ftrufture and colour. The breaft of this is covered with a fhield of a crimfon colour, and fhining like metal ; the head is of the like colour, mixed with green, and on the crown of the head ftands a finning black born bended backwards. Thefe are called the kings of thefe beetles, but 22 NATURAL HISTORY. l>ut for what reafon is uncertain, fince they partake of the fame diftf drudgery with the reft. It is a very ftrong infect, for if one of them foe put under a brafs candleftick it will caufe it to move backwards and forwards as it were by an inviiible hand, to the no fmall admiration of thofe who are not accuftomed to the fight. There is another infect which at firft appears to be of the Beetle kind, to be met with in South-America, and particularly in Surinam. It is of a very heavy fluggifh nature, and is furnifhed with a long tube or trunk under its nofe, which it thrufts into flowers to fuck out the honey. When it is preparing itfelf for transformation, it lies motionlefs for a confiderable time, till at length the {kin breaking on the back, there comes out a flying infect, with four wings that are tranfparent, and of a pale rofe colour, veined with fcarlet, and bordered all round with a pale yellow. The trunk of the body is much the fame as in the Beetle ilate, though it entirely throws oif its fkin or fhell, which was of a deep green colour. When it is transformed to a fly, it is exceeding fwift, and makes a noife with its wings like a harp. There have been the folid (hells of a fort of Beetle brought to England, that weTe found on the eaftern coaft of Africa, over againft part of the ifland of Madagafcar, which the natives hang to their necks, and make ufe of them as whittles to call their cattle together. Their upper fur- face has the appearance of rough wings, which are fo ftrongly united to thofe below after they are dead, that one would imagine they never could be made ufe of while they were alive. On its upper fide it has above a dozen rows of round knobs, running lengthways, and between them there are others that are very fmall. The colour is black, fpot- ted with red between each knot in the rows of the back, and it has alfo red fpots on its under fide. Thefe Beetles when living, will fly with great force againft a perfon's head or face, though when they are dead they feem incapable of any fuch motion as flying. Linnaus divides the Beetles into two kinds, the great and the little j of the former, there are, 1 . The black Beetle, with fpotted and ftreaked cafes of the wings ; the head is fmall, the eyes prominent, the feelers confift of eleven joints, and are as long as half the body. All thefe forts of Beetles have an oblong body, feelers like briftles, a breaft made in the fhape of a heart, an elevated mouth, a ftrong fmell, and they run and fly very fwiftly. This has the fmell of tobacco, and is found among rotten wood. 2. The black Bettle with greenifh cafes of the wings, that are convex- !y fpotted and ftreaked. It is like the former, and has the fame fmell. 3. The black Beetle with the cafes of the wings like copper, and con- vexly fpotted and ftreaked. It is like the former, only the cafes of the wings, the breaft, and the hinder part of the head, are of the colour ©f copper. It is found among rotten wood. 4. The purplifh-black Beetle with the cafes of the wings concavely fpotted and ftreaked. It is the purple fpotted Cerambix of Ray ; and the black Beetle with furrowed cafes of the wings and hollow fpots. It is like the former, and is foupd among putrified vegetables. 5. The black Beetle with eight ftreaks on each wing, is like the former, and is found in the fame places. It is called by Lijler the entirely felack Beetle, with cruftaceous cafes of the wings. 6<, NATURAL HISTORT. *j 6. The blackifh violet Beetle with the cafes of the wings a little wrirv* lied, is called by Fryfch the fmall black Beetle. It is like the former* «nly the edges of the breaft, and the cafes of the wings, are of a blue* ifh purple. 7. The green Beetle with furrowed cafes of the wings, but without points, and the feet and feelers of a brown colour. It refembles the former, only it is green, with a blueiih caft. 8. The black Beetle with green furrowed cafes of the wings, and black feet and feelers. It is the Cerambix of Ray, with a back divided into long lines, and the moft beautiful of all this kind. It is like the for- mer, only the head, breaft, and cafes of the wings above, are of a mining green, marked with three or four ftreaks of different green, between which there are furrows. The edge of the cafes of the wings is of the colour of fire ; but the body, feet,, and feelers are black. Thofe of the leaft fort, according to Linnaus, are, 1. The ftiining Beetle, with head and breaft of a blueiih green, and with purple wings. It fhines like gold, and the cafes of the wings have ftreaks that are hardly vifible. 2. The Beetle which is of a copper colour above, with hollow pointed cafes of the wings, and red feet. The colour of the back is variegated with green, red, copper colour and brown; the cafes of the wings are marked with three points ; the thighs are black, the legs red, and the feelers at the third joint are furnilhed with three filky threads. It is ef the fize of a houle fly, but narrower, and is found in meadows. 3. The black Beetle with red feet, is in fhape and fize like the former, •nly it is quite black, and the cafes of the wings are (freaked. 4. The blackifti Beetle with pale legs, is only half as big as a houfe- fly, and the head, breaft, and cafes of the wings are of a blackifh cop- per-colour, and the cafes of the wings are marked with eight ftreaks. The feet are black, except the middle of the legs. 5. The pale teftaceous Beetle with fmooth wings, is of a middle fize,. with very fmall feelers. 6. The black Beetle with a brown breaft, as well as the feelers and feet. It has a black head, and the cafes of the wings of the fame co- lour, and ftreaked. 7. The Beetle with the head and cafes of the wings blue, and the bread red, or of a faffron colour. The feelers are moftly black, and the feet are variegated with red and black. It is of the fize of a fmall fly. 8. The Beetle with a black head and cafes of the wings, but a red breaft ; it is of the fame fize and fhape as the former, and the feet and feelers are brown. 9. The blackifti copper-coloured Beetle with black feelers and feet, 10 ©f the fize and fhape of the former. The breaft is more black than the ether parts, and fhining,. marked with two hollow fpots ; but the cafes of the wings are ftreaked and filky at the extremities, and the under part of the body is black. 10. The black Beetle with a brown ftreak on the hinder part of the cafes of the wings, and a fpot on the fides of the fame colour, but the feelers are black and red, the feet pale, and the wings brown. 11. The black Beetle with grey cafes of the wings, is about twice the fize of a loufe.. 12, 24 NATURAL HISTORY. 12. The black Beetle with black feet and feelers. The breaft Is fniru ing and narrow at the lower part, but the wings are ftreaked, and on the middle of each there is an hollow point. 1 3. The pale teftaceous Beetle with black eyes, is of the fize of a large loule, and of an opaque colour. The cafes of the wings are ftreaked. 14. The black Beetle with a brown breaft, and the cafes of the wings marked with four livid fpots ; the feet are alfo brown, and there is a brown fpot on the j°ints of the wings. 15. The grey Beetle with the head, belly, and bafe of the cafes of the wings blackiih. It is fcarce fo big as a loufe, and the feelers and feet are grey. Linnaus has feventeen forts of Dermejles ; namely, 1. The black Dermejles with the fore parts of the cafes of the wings of an afh colour ; it is called by Ray the beetle with clavated feelers ; and by Fryfcb the fmall Bacon Beetle, with a tranfverfe ftreak of a whitilh colour, on the duflcy blackiih cafes of the wings. It is fond of bacon, and all forts of dead bodies. 2. The black Dermejles with a double undulated white ftreak on the cafes of the wings ; in which laft particular it differs from the former, but in other refpecls is like it. 3. The black Dermejles with two white fpots on the cafes of the wings. It is named by Fryfch the black Dermeftes, with a white fpot on the cafes of the wings. It is of an oval fhape, and when the cafes of the wings are clofed, two white fpots appear on the back ; befides which there are five others ; that is, one on the point of the corflet, one on each fide the breaft, and one along each cafe, towards each cafe ; but they are all very fmall, and the feelers are in the fhape of a club. It is found among cloaths, on walls, and about provifions. 4. The black Dermejles with two red fpecks on the cafes of the wings. It is called in the tranfaclions of Upjal the Black Dermeftes, with the cafes of the wings marked with a red fpot. This iniecT, as well as the two former, is fond of Bacon. 5. The black Dermejles with four red fpots on the cafes of the wings. is faid by Fryjcb to be a fmail beetle, fpotted with yellow, that pro- ceeds from a hairy worm, found among wool. It may be feen on trees, and fometimes on windows. 6. The fmooth black Dermejles, of a clouded afh-colour, with a yel- low corfet. Fryjcb calls it the Beetle proceeding from a fmooth black caterpillar. 7. The teftaceous hairy Dermejles with ftreaked blunt cafes of the wings ; it is called by Ray the Beetle with ten elevated feelers, and in the Upjal tranfa al- ready defcribed, are the black Unicorn Beetle, with a flatted breaft, and the edge of it having three feet on each fide, and the feelers are coal black : the reddifh Unicorn Beetle with three black lines on the cafes of the wings, running lengthways : the black Unicorn Beetle, with irregular pale fpots on the cafes of the wings, and a prickly breaft ; and has alfo feelers longer than the body : the grey Unicorn Beetle fpotted with black, and a black tranfverfe line on the cafes of the wings, and the feelers longer than the body by one half: the grey Unicorn Beetle, with black cafes of wings fpotted with white, and a white tranf- verfe line on each, with feelers longer than the body by one half: the grey and black Unicorn Beetle, with the feelers about half the length of the body : the grey Capricorn Beetle, with two yellow tranfverfe lines on the cafes of the wings, and the feelers half as long as the body : the fhelly Capricorn Beetle, with a double white tranf- verfe line on each wing. Of the fecond divifion, which have no protuberances on the breaft, there are the black Capricorn Beetle, with two white undulated tranf- verfe lines on the cafes of the wings : the fhelly Capricorn Beetle D 3 with 28 NATURAL HISTORY. with a grey hairy breaft, and two fmooth fhort lines thereon : the fhelly Capricorn Beetle, with a fmooth bread: the blown Capricorn Beetle, with fpots imprefled on the breaft : the grey Capricorn Beetle, with the cafes of the wings fpotted with black : the black Capricorn Beetle, with a longitudinal dentated yellow line and yellow fpots on the cafes of the wings : the fhining violet- coloured Capricorn Beetle, with black feelers and clavated thighs. Linnaus has only four forts in his Syjlema Nature, which are mention- ed among thofe abeve. The Leptura is a fort of a Beetle with feelers like briftles, and the cafes of the wings truncated at the points; as alio a round breaft : the Tree-Beetle, or greater violet- red Leptura, is of the large kind, with an oblong-fhaped body, fmalleft behind : the legs, feelers, and all the other parts, except the cafes of the wings, are black, though in -Jbme lights it has a whitifh caft : the cafes of the wings of the fe- male are of a deep red ; but thofe of the males are not fo deep, and are black or grey on the edges. All the furface of the cafes of the wings in both is adorned with a multitude of fmall hollow dots, with a few fhort fine hairs : the head and breaft are fometimes yellowifh. It may be often met with in the woods, and Ray calls it a Unicorn Beetle, with the head, fhoulders and feelers black ; but of a blackilh yellow at the extremities. The raiddle-fized beetle, with a black oblong narrow belly, and va- riegated with yellow lines and fpots. It is of an oblong narrow fhape, the general colour is of a blackilh brown ; only the upper edge of the breaft is yellow, and there is a yellow fpot where the cafes of the wings join. Likewife there are fome undulated yellow lines running tranf- verfely thereon ; and they are truncated at the point, and are a little hairy, and the feelers and legs are of a reddilh brown. It is not un- common among the hedges in orchards and gardens. The yellow gold-coloured Leptura, with black feelers, and dentated hinder legs : the body is oblong, and the head fmall : the colour refembles that of copper, with a mixture of fine ltrong gilded yellow variegations : the head, breaft, and cafes of the wings, as well as the legs, are all fpeckled with extremely minute, and almoft contiguous hollow dots, which are irregularly difperfed over the breaft, head, and legs; but on the wings they are pretty regular, and placed in ten rows, running lengthways, forming fo may lines : the eyes are black, and the feelers brown. Linnaus has fifteen infecls of this kind, of which the firft is, The greeniih-yellow Leptura, with yellow feelers, variegated with green. It is the largeft of the kind, and in the Upfal transactions is named the greateft black Leptura, greenilh underneath. 2. The black Leptura, with the breaft and cafes of the wings red ; it is pretty large, and the legs are yellow. 3. The black Leptura with blackilh cafes of the wings, variegated with a livid colour. It is found in Sweden as well as the former. 4. The black Leptura with reddilh and greenilh cafes of the wings, is called by Ray the Cerambix, with the head and fhoulders and feelers black, the cafes of the wings yellow and black at the extremity, and in the Upfal tranfactions, the Leptura with teltaceous cafes of the wings ; but this is the. male, and the female is termed the Leptura with red cafea. NATURAL HISTORY. 29 cafes of the wings. It is a fort of a May Bug, and of a violet-red co- lour ; it is commonly feen on bulhes. 5. The black Leptura with the throat, cafes of the wings, and legs purple ; it is like the former, but twice at. big. 6. The black leptura, with the cafes of the wings and breaft yellow- ifh. It is much ot the fame fhape as the former, but lefs. 7. The Leptura with livid cales or the wings, marked with four black fpots. It is of the greatelt fort, and is found in forefts. 8. i he Leptura entirely black, is a little bigger than the former, but the wings are not io large. 9. The black Leptura with teft -ceous cafes of the wings, which are marked with iix black fpots. It is called in the Upfal tranfactions the Leptura, with teftaceous cafes of the wings and black fpots ; it is all over black. 10. The black Leptura with the cafes of the wings marked with four brown fpots, has a black body and wings, and is one of the largeft of the kind. 11. The black Leptura with yellow cafes of the wings, is not fo biff as a loufe, and the feelers are almoft as long as the body, the win°-s are yellow and black at the points. 12. the black Leptura with cafes of the wings marked with tranf- verfe yellow lines, and teliaceous feet. It is called by Lijler the Black Beetle, marked with yellow lines and feet nearly of a faffron colour. It is found in meadows and the branches of trees, and in gardens. 13. The black Leptura with teftaceous wings, marked with two points, with a crois and black ftreaks. 14. The gilded Leptura with black feelers, and the hinder thighs dentated. It is called by Fryfch the Tree-beetle, of a purplilh golden colour, and it is found in moitt places. 15. The Leptura of a violet copper- colour, with the hinder thighs dentated. It is found upon the banks of riveis, and in places where there is much fand and gravel. The violet- black Dung-beetle, called by Ray, the Greater Beetle, with an oblong body, of a purplilh black colour. It has a fmall head, and large prominent eyes, with pretty long, and very flender feelers : the general colour is black, only the edges of the breaft and wings are of a deep beautiful gloffy purple: the cafes of the wings have neither dots nor lines, but they have a fort of wrinkles, which run longways, and others that crofs them, which are not very vifible. It is common on dung-hills, and among rotten vegetables. The purplilh black Dunghill-beetle, called by Ray the Unicorn-Beetle, fpeckled with purple, is ot the large kind, and the body is of an oblong fhape, and pretty thick : the general colour is blackifh, with a ftreng and very fine tinge of gloffy purple : the cafes of the wings are marked with three lines, each of which is formed by a row of longitudinal, hollow, round fpots, and there are about twelve on each row : the lines between them are hollowed. It is found in the fame places as the former. The black Dung-beetle with reddifli legs, is a fmall fpecies, being not much bigger than a common fly : the colour of the body is black, and the breaft is broad and fhort : the cafes of the wings are ftreaked each with eight lines, and the legs are of a reddifli brown, as are alio the 30 NATURAL HISTORY. the bafes of the feelers. Some authors call it the Burn-cow, or Burft- cow, with a black body and red legs. Ltnnaus divides them into two fpecies, namely, the greater or (linking Beetles, and the lelfer or rapacious Beetles. Of the ftinking Beetles, there are the black {linking Beetle with the cafes of the wings convexly ftreaked : the black ftinking Beetle with the cafes of the wings green- ifh, and convexly fpeckled and ftreaked : the black ftinking Beetle with bralfy wings, convexly fpeckled and ftreaked : the black ftink- ing Beetle with lixteen flreaks on the cafes of the wings : the green ftinking Beetle with bluntly ftreaked cafes of the wings, and the head and legs of an iron grey colour : the black ftinking Bettle with green ihallow furrowed wings, and black feelers and legs. The Mordella is an infect of the Beetle kind, with feelers like threads, and have generally legs that ferve them for leaping. It is called by the German Waflerwante ; but we have no Englifo name for it : the oblong Black Mordella, with a flender pointed tail, is not above a fixth part of an inch in length, and the breadth not half fo much : the colour is black, and it is fmooth and a little glolfy on moil part of the furface : the head is fmall and bent, and the cafes of the wings have no ftreaks ; the breaft is fmooth, and very convex, and the feel- ers are very flender, truncated, and jointed : the body grows gradu- ally fmaller towards the tail, where it terminates in a fharp thorn or prickle, which is black, and reaches longer than the extremity of the wings : the legs are flender and long, by which means it leaps very nimbly. The roundilh. opake black Mordella is fhorter and thicker than the former, being nearly of a roundilh fhape : the head is fmall, and the breaft railed, being of a dulky deep black, but not glolfy : the cafes of the wings are of the fame colour, and fomewhat fhorter than the body, but the legs are flender and long, which enable it to leap very brifkly. It is common in gardens. The ihining blue oval- bodied Mordella, called by Ray the fmall leaping Capricorn Beetle, is not much larger than a flea, and the body- is fhort, being nearly of an oval form : the breaft and back are both very convex and fmooth, and of a very deep, beautiful, glolfy blue colour : the legs are long, the thighs thick, robuft, and whitifh, and the lower part of the legs are of an iron-grey colour. It hops very nimbly, and is common among cabbages, while they are young. The roundilh black Mordella with a bralfy tinclure, is much lefs than a flea, and is all over of a very deep glolfy black, with a fine bralfy yellowilh caft : the belly and legs are of the fame fine black, but without the yellow : the cafes of the wings are marked with ftreaks, that confift of five fmall hollow fpots. It may be feen in the gardens early in the fpring. Linnaus has only three kinds, to which he gives no very diftincT: marks ; however there are other fpecies, as the yellow Mordella; the roundilh moufe-coloured Mordella ; the roundilh black opake and dotted Mordella; the roundilh black glolfy Mordella with yellow feelers and legs : the oblong black Mordella with an iron-grey fpot on each cafe pi the wings, whole fides are of the fame colour towards the bafe : the pblong black Mordella with the cafes of their wings yellow down their middle : the reudifh-brown Mordella vrith the fore-legs dentated ; the Natural history. p the black Mordella with the cafes of the wings red at their extremi- ties : the brown opake Mordella with the cafes of the wings fpeckled ; the iron grey brown Mordella, with the breaft depreffed on the fore part: the Mordella with the joints of a little lOBgifti fhape, except that at the end, which is perfectly round. The Cicindela has feelers like threads or briftles, prominent dentated jaws, and a roundiih breaft, though fomewhat angular :• the Green Beetle with ten white fpots of Ray is a Cicindela, and is a very beauti- ful infect ; the upper furface of the body fhining, and variegated with green and gold : the cafes of the wings are fmootb, gloffy, of the lame colour, and marked with ten white fpots, fome of which are round- iih, fome oblong, and one in the figure of a half moon ; likewife the extremities of thefe cafes are white : the breaft is narrow, roundiih, and of a deep green ; the head is fmall, deprelfed, and finely tinged with gold colour : the eyes are black and prominent as well as the mouth, and the upper lip is blunt and whife : the upper jaws are alio prominent, and have feveral ftrong teeth therein ; but the lower has only one tooth, and that at the extremity : there are two pair of feel- ers, one of which confifts only of two joints, and the other of ten : the legs are very long and (lender, and there is a kind of hard oval lub- ftance at the bafe of the thighs. It is common in pafture ground in the fpring, and runs and flies very fwiftly. The fmall gilded beetle is a fmall fpecies, and its colour is fine and glofTy, refembling a yellow metal with a little mixture of green s the eyes are black and prominent, the breaft narrow and rounded ; and the cafes of the wings are adorned with many broad hollow fpecks in the centre of each of which there is a prominent point : thefe hol- low fpecks are placed in rows, and are a deep black ;-but their bottoms are of a fine metalline yellow. Upon the whole it is a very beautiful infect, and may be eafily found on the banks of rivers. The Cicindela with the cafes of the wings of a blueilh green, and a yellow belly ; the body is nearly of an oval fhape, and the head, breaft, feelers and legs, are all black : the belly is of a yellowifh taw- ny colour, and the cafes of the wings of a blue green,, variegated with hollow fpecks : the feelers are {lender, and coniifts of ten joints : this infect is common in the woods. The black Cicindela with the cafes of the wings marked with fix white fpots, and a white ftreak. It is found in the woods, and runs and flies very fwiftly. It is quite black, except the wings, marked as above, and the thighs and feet are long, flender, and a little hairy. The black Cicindela with a red breaft, and blackifii blire cafes of the wings : this infect has black feelers, of the length of the body, and the head and feet are of the fame colour ; but the breaft is of a reddh'h brown and the cafes of the wings black, with a bluerlh caft, marked with very fmall points : the belly is yellow behind, and oblong and aarrow. The Cicindela with blueifh cafes of the wings, and the belly of a fal- low colour. It is found at the bottoms of mountains, and in fhady places, and is of the fame lhape as the former : the head, breaft, feet, and feelers are black, and the belly, near the feet, is of a fallow colour, but the cafes of the wings are of a mining blue,.. marked with hollow joints, and the feelers confift of fix joints. The g« NATURAL HISTORY. The Cic'indela with a green breaft, with the cafes of the wings of aii iron grey, but behind of a blueilh black : the feelers are black, the body and the bread: of a fhining blue. The Burn-cow, or Bur/l-coiu, called in Latin Bupreftis, is an infecl with feelers like threads or briftles, and the head half hid within their breaft, and of a roundifh fhape : the yellowifh green Burn-cow with- out fpots, is placed by fome among the Cantharides, only it has a more oblong body : the cafes of the wings are of a greenifh yellow, or rather of a gold colour ; the legs are long and thickilh, the eyes glo- bous and prominent 5 and from the forehead near the eyes, there are two oblong horns or feelers, which are articulated : the head is imall, the mouth wide, hard, ftrong, and forked ; being armed with teeth, with which it bites very hard : the belly is not round, but longifh. It will fight with Beetles and efts, wounding them in the belly. It is about half an inch long, and feeds upon mofs, heath, efts, worms, and other infe&s, which it vanquifhes in fight. Nor will it touch any that are killed by other means. Belonius defcribes it thus ; it is a winged flying infect, having a moft filthy fmell, and is like a Cantharis, but larger, and is of a yellowifh colour, and fo very venomous, that horn- ed cattle which feed in paftures where they are, are often killed there- with : this however differs from the former in the colour. There is another Burn-coiv, with a fhorter body and a broader belly; as alfo a fharper tail, and a fmall head, with prominent eyes, and a wide forked mouth : the cafes of the wings are ftreaked lengthways, and the colour is as green as grafs, with a mixture of mining gold. It has eight legs, which are long in proportion to the body ; but more {lender than in the former fpecies, and of a blackifh colour, the feelers are more fmall and flender, and it is as nimble as the firft, but has a a much more filthy fmell. It lives upon flies and palmer- worms : thefe are venomous to cattle like the former ; and fome affirm if one of them be fwallowed it will poifon a man. - In Germany there are alfo two other forts, the one of a greenifh gold i colour, and the other of a yellow black : the fiift is like the former above defcribed, but is a little bigger, and the cafes of the wings are ftreaked with lines of a deep gold- colour, fhaded with a little green j and between the lines hollowifh tubercles arife, which look as if they were engraved therein. It is very nimble, and in that is like the other kinds : the yellowifh-black Burn-courn-cow, is a very fmall fpecies, though the eyes are pretty large an^ prominent : the feelers are fliort, and the breaft is lhort, and broad, but hollowed, and has a very fmall rim : the cafes of the wings are very bright and gloffy, and finely ftreaked with very minute elegant fpecks : the legs are flender and black, as well as the under part of the body, and the fnout is prominent. It is common among the reeds near rivers. The braffy and clouded H>urn-Co minent head, and fomewhat of a neck : the wings feem likewife to be ufelefs for flying, though they help to raife this infect up. It is com- monly feen fitting upon water-plants, and is faid to fing like the land Crickets. But of all the cricket kind, that which is called the Mole-Cricket is- the mod extraordinary. This animal is the larged of all the infects - with which we are acquainted in this country, being two inches and a half in length, and three quarters of an inch in breadth. The colour is of a dufky brown ; and at the extremity of the tail there are two hairy excrefcences, refembling in fome fenfe the tail of a moufe. The body confids of eight fcaly joints or feparate folds, is brown on the upper part, and more deeply tinged below. The wings are long, nar- row, and terminate in a fliarp point, each having a blackilh line run- ning down it : however, when they are extended, they appear to be much broader than could at fird fight be fuppofed. The Ihield of the bread is of a firm texture, of a blackifli colour and hairy. The fore- feet, which are this animal's principal indruments of burrowing into the earth, are drong, webbed, and hairy ; it generally, however, runs backward ; but it is commonly under ground, where it burrows even fader than a mole. It is thought alfo to be amphibious ; and capable of living under water, as well as under ground. Of all infects this is the mod deteded by gardeners, as it chiefly re- fides in that ground which lies light, and where it finds fufficient plenty under the furface. Thus, in a tingle night's time, it will run along a- furrow which has been newly fown, and rob it of all its contents. Its legs are formed in fuch a manner that it can penetrate the earth in every direction ; before, behind, and above it. At night it ventures from its under ground habitation, and, like the cricket, has its chirp- ing call. When the female is fecundated, (he makes a cell of clammy earth, the infide of which is large enough to hold two hazle-nuts ; and in this fhe lays her eggs. The whole ned is about the fize of a com- mon hen's egg, clofed up on every fide, and well defended from the finalleft breath of air. The eggs generally amount to the number of NATURAL HISTORY. 43 an hundred and fifty, being white, and about the fize *f a carraway- comfit. They are thus carefully covered, as well to defend them from the injuries of the weather, as from the attacks of the black- beetle ; that being itielf an under ground inhabitant, would, but for this pre- caution, devour or deftroy them. To prevent this, the female mole cricket is often pofted as a centinel near the neft, and when the black 'invader plunges in to feize its prey, the guardian infed feizes him be- hind, and inllantly bites him in two. Nothing can exceed the care and afliduity which thefe animals exhi- bit in the prefervation of their young. Wherever the neft is placed, their feems to be a fortification, avenues, and entrenchments, drawn round it: there are numberlefs winding-ways that lead to it, and a ditch drawn about it, which few of its infecT: enemies are able to pafs. But their care is not confined to this only ; for at the approach of winter they carry their neft entirely away, and fink it deeper in the ground, fo that the froft can have no influence in retarding the young brood from coming to maturity. As the weather grows milder, they raife their magazine in proportion ; till, at laft they bring it as near the fur- face as they can, to receive the genial influence of the fun, without wholly expofing it to view : yet, lhould the froft unexpectedly return, they fink it again as before. Belonging to the fecond order of infects, we find a tribe of little ani- mals, which, though differing in fize and colour, ftrongly referable each other in figure, appetites, nature, and transformation. But though they all appear of one family, yet man has been taught to hold them in different eftimation ; for while fome of this tribe amufe him with their chirpings, and banifh folitude from the fields, others come in fwarms, eat up every thing that is green, and in a fingle night con- vert the moft delightful landfcape into a dreary wafie. However, if thefe animals be feparately confidered, the devouring locuft is not in the leaft more mifchievous than the mufical grafshopper ; the only de- ference is, that one fpecies come for food in a fwarm, the other feeds fmgly. That animal which is called the Srafshop;»r with us, differs greatly from the cicada of antiquity ; for as our infeft is aclive enough in hop- ping through the long grafs, from whence it has taken its name, the cicada had not this power, but either walked or flew. The little huf- fing note alfo of our grafshopper is very different from the fong of the cicada, which was louder and far more mufical. The manner in which this note is produced by the two animals is very different ; for the ci- cada makes it by a kind of buckler, which the male has beneath its belly; the grafshopper by a tranfparent membrane that covers an hole at the bafe of its wings. There is ftill a greater variety in all thefe with regard to fhape and colour. Some are green, fome black, fome livid, and fome variegated ; but many of them do not fhew all their colours till they fly. Some have long legs, fome fhort ; fome with more joints, others with fewer. Some fing others are mute; fome are innocent, doing no damage to the hufbandman ; while others do fuch prodigious mifchief, that they are looked upon in fome countries as .one of the terrible fcourges of the incenfed Divinity. Of this variegated tribe, the little grafshopper that breeds in fuch siienty in every meadow, and that continues its chirping through the w * * y z fummcr, 44 NATURAL HISTORY. fummer, is befl*known to us; and by having its hiftroy we fnall be po£ fefTed of that of all the reft. This animal is of the colour of green leaves except a line of brown which ftreaks the back, and two pale lines under the belly and behind the legs. It may be divided into the head, the ccrflet, and the belly. The head is oblong, regarding the earth, and bearing fome refemblance to that of a horfe. Its mouth is covered by a kind of round buckler jutting over it, and armed with teeth of a brown colour, hooked at the points. Within the mouth is perceivable a large reddifh tongue, and fixed to the lower jaw. The feelers or horns are very long, tapering off to a point; and the eyes are like two black fpecks, a little prominent. The corflet is elevated, nar- row, armed above and below, by two ferrated fpines. The back is armed with a ftrong buckler, to which the mufcles of the legs are firmly bound, and round thefe mufcles are feen the veflels by which the ani- mal breathes, as white as fnow. The laft pair of legs are much longer and ftronger than the firft two pair, fortified by thick mufcles, and very well formed for leaping. It has four wings ; the anterior ones fpringing from the fecond pair of legs, the pofterior from the third pair. The hinder wings are much finer and more expanfive than the fdremoft, and are the principal inftruments of its flight. The belly is confiderably large,. compofed of eight rings, and terminated by a for- Icey tail, covered with down, like the tail of a rat. When examined internally, befides the gullet, we difcover a fmall ftomach ; and behind that a very large one, wrinkled and furrowed within fide : lower down there is ftill a third ; fo that it is not without reafon that all the ani- mals of this order are faid to chew the cud, as they fo much refemble ruminant animals in their internal conformation. A fhort time after the grafshopper afTumes its wings, it fills the mea- dows with its note ; which like that among birds, is a call to courtfhip. The male only of this tribe is vocal ; and, upon examining the bafe of the wings, there will be found a little hole in its body, covered with a fine tranfparent membrane. This is thought, by Linnaeus, to be the inftrument it employs in finging ; but others are of opinion the found is produced by rubbing its hinder legs againft each other : however this be, the note of one male is feldom heard, but it is returned by another ; and the two little animals, after many mutual infults of this kind, are feen to meet and fight defperately. The female is generally the reward of victory ; for, after the combat, the male feizes her with his teeth behind the neck, and thus keeps her for feveral hours, till the bufinefs of fecundation is performed. They are at that time fo ftrongly united, that they can fcarcely be feparated without tearing afunder. Towards the latter end of autumn the female prepares to depofit her burthen ; and her body is then feen greatly dittended with her eggs, which fhe carries to the number of one hundred and fifty. In order to make a proper lodgement in the earth for them, Nature has furnifhed her with an inftrument at her tail, fomewhat refembling a two-edged fword, which fhe can fheathe and unfheathe at pleafure : with this fhe pierces the earth as deep as fhe is able ; and into the hole which her inftrument has made, fhe depofits her eggs, one after the other. Having thus provided for the continuation of her pofterity, the ani- mal herfelf does not long furvive ; but, as the winter approaches, fhe dries NATURAL HISTORY. 45 dries up, feerns to feel the effects of age, and dies from a total decay. Some, however, afTert, that lhe is killed by the cold ; and others, that ihe is eaten by worms : but certain it is, that neither the male, nor female are ever feen to furvive the winter. In the mean time the eggs which have been depofited, continue unaltered, either by the fe- verity of the feafon, or the retardation ot the fpring. They are of an oval figure, white, and of the confidence of horn: their fize nearly equals that of a grain of anife : they are enveloped in the body within a covering, branched all over with veins and arteries ; and when ex- cluded, they crack, on being prelfed between the fingers ; their fub- ftance within is a whitifh, vifcous, and tranfparent fluid. In this man- ner they remain depofited beneath the furface of the earth, during the whole winter; till the genial return of fpring begins to vivify and hatch them. The fun, with its warmth, beginning to animate all Nature, the infect eggs feel its benign influence ; and generally, about the be- ginning of May, every egg produces an infect, about the fize of a flea. Thefe at firft are of a whiciih colour ; at the end of two or three days they turn black ; and foon after they become of a reddifh brown. They appear, from the beginning, like grafshoppers wanning wings ; and hop among the grafs as foon as excluded, with great agility. Yet ftill they are by no means arrived at their ftate of full perfec- tion; although they bear a firong refemblance to the animal in its per- fect form. They want, or feem to want the wings, which they are at laft feen to affume ; and can only hop among the grafs, without being able to fly. The wings, however are not wanting, but are concealed within four little bunches, that feem to deform the fides of the animal: there they lie rolled up in a moft curious manner ; and occupying a fmaller ipace than one would conceive who faw them extended. In- deed, all infects, whatever tranfmutations they feem to undergo, are yet brought forth with thofe \rery limbs, parts and wings, which they afterwards feem to acquire. In the moft helplefs catei pillar, there is ftill to be feen the rudiments of that beautiful plumage which it after- wards expands when a butterfly : and though many new parts feem unfolded to the view, the animal acquires none but fuch as it was from the beginning poffefTed of. The grafshopper, therefore, though fsem- ingly without wings, is in reality, from the firft, pofTeifed of thole inftru- ments, and only waits for fufficient force to break the bonds, that hold them folded up, and to give them their full expanfion. The grafshopper, that for above twenty days from its exclufion has continued without the ufe of its wings, which are folded up to its body, at length prepares for its emancipation, and for a life of greater liberty and pleafure. To make the proper difpofitions for the approaching change, it ceafes from its grafly food, and feeks about for a convenient place ; beneath fome thorn or thiftle, that may protect it from an acciden- tal fhower. The fame laborious writhings and workings, heavings ■and palpitations, which we have remarked in every other infect upon an approaching change, are exhibited in this. It fwells up its head and neck ; it then feems to draw them in again ; and thus alternately, for fome time, it exerts its powers to get free. At length, the fkin covering the head and breaft is feen dividing above the neck; the head is feen ilfuing out firft from the burfting fkin ; the efforts ftill continu- ing, the other parts follow fucceffively j fo that the little animal, with its 46 NATURAL HISTORY. •its long; feelers, legs and all, works its way from the old fkin, that re- mains fixed to the thiftle or the thorn. It is, indeed, inconceivable how the infed can thus extricate itfelf from fo exaft a (heath as that whick covered every part of its body. The grafshopper, thus difengaged from its outer fkin, appears in its perfect form ; but then fo feeble, and its body fo foft and tender, that it may be moulded like wax. It is no longer of that obfcure colour which it exhibited before, but a greenifh white, which becomes more vivid as the moifture on the furface is dried away. Still, however, the ani- mal continues to (hew no figns of life, but appears quite fpent and fa- tigued with its labour for more than an hour together. During this time, the body is drying, and the wings unfolding to their greateft . cxpanfion, and the curious obferver will perceive them, fold after fold, opening to the fun, till at laft they become longer than the two hin- der legs. The infe&'s body alfo is lengthened during this operation, and it becomes much more beautiful than before. Thefe infects are generally vocal in the midft 6f fummer, and they are heard at funfetting much louder than during the heats of the day. They are fed upon grafs ; and, if their belly be preffed, they will be feen to return the juices of the plants they have laft fed upon. Though unwilling to fly, and flow in flight, particularly when the weather is moid or cool, they are fometimes feen to fly to confiderable diftances. If they are caught by one of the hinder legs, they quickly difengage themfelves from it, and leave the leg behind them. This, however, does not grow again, as with crabs or fpiders ; for as they are animals but of a Angle year's continuance, they have not fufficient rime for repairing thofe accidental misfortunes. The lofs of their leg alfo prevents them from flying ; for being unable to lift themfelves in the air, they have not room upon the ground for the proper expanfion of their wings. If they be handled roughly, they will bite very fiercely; and when they fly, they make a noife with their wings. They general- ly keep in the plain, where the grafs is luxuriant, and the ground rich and fertile : there they depofit there eggs, particularly in thofe cracks which are formed by the heat of the fun. Such are the habits and nature of thofe little vocal infedls, that fwarm in our meadows, and enliven the landfcape. The larger kinds only differ from them in fize, in rapidity of flight, and the powers of in- juring mankind, by fwarming upon the production of the earth. The quantity of grafs which a few grafshoppers that fport in the fields can deftroy is trifling ; but when a fwarm of locufts, two or three miles long, and feveral yards dgep, fettle upon a field, the confequences are frightful. The annals of every country are marked with the devalua- tion which fuch a multitude of infetts produces ; and though they-fel- dom vifit Europe in fuch dangerous fwarms as formerly, yet, in fome of the fouthern kingdoms, they are ftill formidable. Thofe which have at uncertain intervals vifited Europe, in our memory, are fuppofed to have come from Africa, and the animal is called the great Brown Lo- cuft. It was feen in feveral parts of England in the year 1 748, and many dreadful confequences were apprehended from its appearance. This infecT: is about three inches long ; and has two horns or feelers, an inch in length. The head and horns are of a brownifh colour ; it k blue about the mouth, as alfo on the infide of the larger legs. The flueH NATURAL HISTORY. 4f 4 lield that covers the back is greenifh ; and the upper fide of the body brown, fpotted with black, and the under fide purple. The upper wings are brown, with fmall dufky fpots, with one larger at the tips ; the under wings are more tranfparent, and of a light brown, tinctured with green, but there is a dark cloud of fpots near the tips. This is that in- fect that has threatened us fo often with its vifitations ; and that is fo> truly terrible in the countries where it is bred. There is no animal in the creation that multiplies fo fall as thefe, if the fun be warm, and the foil in which their eggs are depofited be dry. Kappily for us, the eoldnefs of our climate, and the humidity of our foil, are no way fa- vourable to their production ; and they are but the animals of a year, they vifit us and perilh. The Scripture, which was written in a country where the locuft made a diftinguifhed feature in the picture of Nature, has given us feveral very ftriking images of this animal's numbers and rapacity. It com- pares an army, where the numbers are almoft infinite, to a fwarm or locufts : it defcribes them as rifing out of the earth, where they are pro- duced ; as purfuing a fettled march to deftroy the fruits of the earth, and co-operate with Divine Indignation. When the locufts take the field, as we are allured, they have a leader at their head, whofe flight they obferve, and pay a ftiict attention to- all his motions. They appear, at a diftance, like a black cloud, which, as it approaches, gathers upon the horizon, and almoft hides the light of the day. It often happens that the hufbandman fees this imminent calamity pafs away without doing him any mifchief ; and the whole fwarm proceed onward, to fettle upon the labours of fome lefs for- tunate country. But wretched i3 the diftrict upon which they fettle 3 they ravage the meadow and the pafture ground ; ftrip the trees of their leaves, and the garden of its beauty : the vifitation of a few mi- nutes deftroys the expectation of a year ; and a famine but too fre- quently enfues. In their native tropical climates they are not fo dread- ful as in the more fouthern parts of Europe. There, though the plaift and the foreft be ftriped of their verdure, the power of vegetation is €0 great, that an interval of three or four days repairs the calamity : but cur verdure is the livery of a feafon ; and we muft wait till the enfuing fpring repairs the damage. Befides, in their long flights to this part of the world, they are famifhed by the tedioufnefs of their journey, and are therefore more voracious wherever they happen to fettle. But it is not by what they devour that they do fo much damage as by what they deftroy. Their very bite is thought to contaminate the plant, and to prevent its vegetation. To ufe the expreilion of the hufband- man, they burn whatever they touch ; and leave the marks of their de- valuation for two or three years enfuing. But if they be noxious while living, they are ftill more fo when dead ; for wherever they fall, they infeft the air in fuch a manner that the fmell is infupportable. Oro^- fius tells us, that in the year 3800, there was an incredible number of locufts which infefted Africa ; and, after having eaten up every thing that was green, they flew off and were drowned in the African lea ; where they caufed fuch a flench, that the putrifying bodies of hundreds ef thoufands of men could not equal it. In the y'ear 1690, a cloud of locufts was feen to enter Rufiia in tbttte different places} and from thencs to fpread thsmfelves o»er Poland and 48 NATURAL HISTORY. and Lithuania, in fuch aftonifhing multitudes, that the air was darken- ed, and the earth covered with their numbers. In fome places they were feen lying dead, heaped upon each other four feet deep ; in others* they covered the furface like a black cloth : the trees bent beneath their weight ; and the damage which the country fuftained exceeded computation. In Barbary their numbers are formidable, and their vi- fits are frequent. In the year 1724, Dr Sbaw was a witnefs in that country of their devastation. Their firft appearance was about the lat- ter end of March, when the wind had been foutherly for fome time. In the beginning of April, their numbers were fo vaftiy increafed, that in the heat of the day they formed themfelves into large fwarms, which appeared like clouds, and darkened the fun. In the middle of May they began to difappear, retiring into the plains to depofit their eggs. In the next month, being June, the young brood began to make their ap- pearance, forming many compact bodies of feveral hundred yards fquare ; and afterwards marching forward, climbed the trees, walls, and houfes., eating every thing that was green in their way. The inhabitants, to (lop their progrefs, laid trenches all over their fields and gardens, filling them with water. Some placed large quantities of heath, ftubb'e, and fuch like combuftible matter, in rows, and fet them on fire on the approach of the locufts. But all this was to no purpofe ; for the trenches were quickly filled up, and the fires put out by the vaft number of fwarms that fucceeded each other. A day or two after one of thefe was in motion, others that were juft hatched came to glean after them, gnawing off the young branches and the very bark of the trees. Having lived near a month in this manner, they arrived at their full growth, and threw off their worm-like ftate, by calling their ikins. To prepare themfelves for this change, they fixed their hinder feet to fome buih or twig, or corner of a ftone, when im- mediately, by an undulating motion ufed on this occafion, their heads would firft appear, and foon after the reft of their bodies. The whole transformation was performed in feven or eight minutes time ; after which, they were a little while in a languifhing condition ; but as foon as the fun and air had hardened their wings, and dried up the moiflure that remained after carting off their Houghs, they returned again to their former greedinefs, with an addition both of Strength and agility. But they did not continue long in this ftate before they were entirely difperfed ; after laying their eggs, directing their courfe northward, and probably perifhing in the fea. It is faid that the holes thefe ani- mals make, to depofit their eggs in, are four feet deep in the ground ; the eggs are about fourfcore in number, of the fize of carraway comfits and bundled up together in clufters. It would be endlefs to recount all the mifchiefs which thefe famifhed infecls have at different times occafioned ; but what can have induced them to take fuch diiiant flights, when they come into Europe, is not fo eafy to be accounted for. It feems moft probable, that by means of a very dry feafon in the heart of Africa, they are propagated in fuch numbers, that the vegetables of the fpot where they are produced are not fufficient to fuftain them. Thus being obliged to find out other countries, they traverfe the fandy deferts, where they can find no fuf- tenance ; ftill meeting with nothing to allure them from their height, they NATURAL HISTORY. 4d they proceed forward acrofs the fea, and thus come into Europe, where they alight upon the flrft green pallures that occur. * In i'ome parts of the world, the inhabitants turn what feems a plague to their own advantage. Locufts are eaten by the natives in many kingdoms of the eaft ; and are caught in fmall nets provided for that .purpofe. They parch them over the fire in an earthen pan ; and when, their wings and legs are fallen off, they turn reddilh, of the colour of boiled fhrimps. Dampier has eat them thus prepared, and thinks therri a tolerable diih. The natives of Barbafy alfo eat them fried with fait; and they are laid to tafte like cray-filh. There is a Iocuft in Tonquin, about the bignefs of the top of a man's fincer, and as long as the firft joint. It breeds in the earth, in low- grounds ; and in the months of January and February, which is the feafon for taking them, they iffue from the earth in vaft fwarms. At firft they can hardly fly, fo that they often fall into the rivers in great numbers : however, the natives in th -fe months watch the rivers, and: take them up in multitudes in fmall nets. They either eat them frefh, broiled on the coals, or pickle them for keeping. They are considered as a great delicacy in that part of the world, as well by the rich as the poor. In the countries where they are eaten, they are regularly brought to market, and fold as larks or quails in. Europe. They mult have been a common food with the Jews, as Mofes, in the book of Leviti- cus, permits them to eat four different kinds of this animal, which he takes care to lpecify. This diih, however, has not yet made its way into the kitchens of the luxurious in Europe : and though we may ad- mire the delicacies of the Eaft, we are as yet happily deprived of the power of imitation. Of all animals, however, of this noxious tribe, the Great We ft- Indian Locuft, individually confidered, is the molt formidable. It is about the thicknefs of the barrel of a goofe-quill, and the body is divided in- to nine or ten joints, in the whole about fix or feven inches long. It has two fmall eyes, (landing out of the head like thofe of crabs, and two feelers like long hair. The whole body is ftudded with fmall ex- crefcences, which are not much bigger than the points of pins. The fhape is roundilh, and the body diminifhes in circumference to the tail, which is forked into two horns. Between thefe, there is a fort of a fheath containing a fmall dangerous fting. If any perfon happens to touch this infect he is lure to be ftung ; and is immediately taken with a fhivering and trembling all over the body ; which, however, may foon be put a flop to, by rubbing the place that was affected with a little palm oil. Nieuhojf informs us, that in the Eajl- Indies there are Grafshoppers and Locufts of feveral kinds, one of which is as long as a man's finger, but no thicker than a goofe quill. The body is diftinguiihed into feveral joints, and they have fix feet, with two fmall horns or feelers. Other Locufts have brown wings, with a yellow belly, and two feelers, and they can leap a great way. They are likewiie feen flying together in great fwarms. There is another fort, of the fame fhape, but green, and of the length of a man's finger; but they come in fuch prodigi- 6us fwarms, that they devour every thing that is green in the places where they fettle ; infomuch that the inhabitants of Batwoia are often ♦b'iged to change their habitations, for want of their uilial iulienance. G L; 5o NATURAL HISTORY. Le Bruin informs us, on the 9th of Oftober near Rama in the Hofy Land, there was a fouth-eaft wind, which blew over the wildernefs, and caufed a violent heat, that lafted feveral days. He is of opinion, that it is to this wind, that the prodigious number of Locufts are owing, which flock thither in certain years, and cover the furface of the earth. In the fpace of two hours, they devoured all the grafs and herbs round about Rama. There are many birds that feed upon them, and parti- cularly dorks. At the time when the locufts engender, they make holes in the earth, about four feet deep, where they lay their eggs, which are about the fize of caraway comfits, there being bundles of them together,, at lead four-fcore in number. In fifteen or fixteen days time, they become young Locufts, and are all over black, when firft hatched ; but in twenty-four hours they change, and become green ; however it is three weeks before they can ufe their wings. In many places where thefe infects die upon the ground, there arifes fuch a ftenclv from theif bodies, that it often breeds a dreadful plague. CHAP. III. OF TOUR WINGED INSECTS. OF thefe there are feveral forts, the firft of which mentioned by Lin' naus, is the Cicada, by which Dale underftands a Bawm Cricket $'■ but he means an infect that has a fnout bent downwards, very fhort feelers, four cruciated wings, feet proper for leaping, a convex back, and a roundifh breaft. The Cuckoiu-Spit infect, called by Swammerdam the Flea-Locuft, and by others the Froth Worm, has an oblong, obtufe"body, and a large- head, with fmall eyes : the external wings are of a duiky brown co- lour, marked with two white fpots, and there is a broad, tranfverfe, double line of the fame: the reft of the body is of a dulky brown, and the head is black. It is ufually covered over with a frothy matter, refembling fpittle, which it does not difcharge at the mouth, but at the vent, and at other parts of the body. The Cicada with green wings and a yellow head, is as big as a large flie, but very narrow in proportion to its length : the external wings are of a fine deep green, and the internal of a blueifh grey ; the cover- ing of the breaft is alfo green, but paler than the wings, and the head is yellow, marked with two large fpots on the hinder part, and feveral fmall ones at the fides: there are alfo tranfverfe ftreaks on the forehead, and the body is of a blueifii-grey, with yellow legs. It is commonly feen about water-plants in autumn, /fay- calls it the third flea Locuft. The Cicada with yellow external wings, is about the (ylq of a com- mon flie, is all over of a beautiful yellow, except when the wings are clofed, and then a longitudinal black line appears on each fide the back, which is fo divided in the middle, to form as it were two lines, the one running from the breaft, and the ether from the tail to the middle, where they are obliquely feparated : the two upper parts of thefe lines join- NATURAL HISTORY. 51 Tio'tn -near the breaft, and there is on each fide, a black fpot on the head and breaft, but they both unite into one: the feelers are ihort, the fore-head is a little furrowed tranfverfely, and the body, when the wings are extended, appears to be yellow on the middle, and black on each fide. It may be met with in pafture grounds in June. Linnaus has eight forts of Cicada, which he calls the American La- ternaria, the Chinefe Laternaria, the Ranatra, the flea Locuft, the Ci- cada with a double homed breaft, the Cicada bearing manna, the Ci- cada of the elm-tree, and the Cicada of the rofe. Other authors have the Italian or true Cicada, which is an inch long, more than half an inch broad, and of a dufky-brown colour: the fmaller Italian Cicada: the brown Cicada, with wings fpotted with paler brown, and with punctated nerves: the black Cicada with three equal tranfverfe ■white lines : the yellow Cicada with wings fpotted with brown, and marked with four black ipots, but yellow on the hinder part: the whitiih Cicada with a black longitudinal line on each fide : the black Cicada with white eyes : the black Cicada with the edges of the exter- nal wings white: the black Cicada with a white head : the yellow com- preffed Cicada : the Cicada with greenifh yellow wings, with the ex- tremities black, and gilded : this is the elm Cicada mentioned by L«i- tiaus : the yellow Cicada with the exremity of the wings white and membranaceous": the leaft white Cicada. The proper Cimex is generally underftood to mean only a common Bug; and Linnxus defines it to be an infect: with a fnout bending down- wards, and feelers that have four joints, four cruciated wings, feet proper for running, a flat back, and a marginated breaft. This is one of thofe naufeous infects that intrude upon the retreats of mankind ; and that often banifh that fleep, which even forrow and anxiety permitted to approach. This, to many men, is, of all other infects, the moft troublefome and obnoxious. The night is ufually the feafon when the wretched have reft from their labour ; but this feems the only feafon when the bug iiTues from its retreats, to make its de- predations. By day it lurks like a robber, in the moft fecret parts of bed ; takes the advantage of every chink and cranny, to make a fecure lodgment; and contrives its habitation with fo much art, that fcarce any induftry can difcover its retreat. It feems to avoid the light with great cunning ; and even if candles be kept burning, this formidable infect will not iftue from its hiding-place. But when darknefs promi- fes fecurity, it then iftues from every corner of the bed, drops from the tefter, crawls from behind the arras, and travels with great affi- duity to the unhappy patient, who vainly wifhes for reft and refrefli- ment. It is generally vain to dei'.roy one only, as there are hundreds more to revenge their companion's fate; fo that the pcrl'on who thus is fubject to be bitten, remains the whole night like a centinel upon duty, rather watching the approach of frefh invaders, than inviting the pleating approaches of Heap. Nor are thefe infects le'fs difagreeable from their naufeous flench, than their unceaiing appetites. When they begin to crawl, the whole bed is infected with the fmell ; but if they are accidentally killed, then it is infupportable. Thefe are a part of the inconveniences that refult from the perfecution ef thefe odious infects; but happily for Great Britain, they multiply left G z in 5* NATURAL HISTORY. in thefe iflands, than in any part of the continent. In France and Ttafy the beds, particularly in their inns, fwarm with them; and every piece of furniture feems to afford them a retreat. They grow larger alfo with them than with us, and bite with more cruel appetite. This animal, if examined minutely, appears to conlift of three prin- cipal parts ; the head, the corlelet, and the belly. It has two brown eyes, that are very fmall and a little prominent, befides two feelers, with three joints : underneath thefe there is a crooked trunk, which is its inftrument of torture, and which, when in motion, lies clofe upon the breaft. The bread is a kind of ring, in which are placed the two firft pair of legs. The belly confifts of nine rings ; under which are placed two pair of legs more, making fix in all. Each leg has three joints, which form the thigh, the leg, and the foot, which is armed with a crooked claw, like an hook. The body is fmooth, except a few fhort hairs, that may be feen by the microfcope, about the vent, and on the two laft rings. Its motion is flow and unwieldy ; yet its fight is fo exquifite, that the inftant it perceives the light, it generally makes good its retreat ; and they are feldom caught, though the bed fwarms ■with them. If we examine this infect internally, we fhall find the great artery, which in all infects performs the functions of the heart ; we fhall find the apertures of the lungs on the right fide and the left, through which the animal breathes ; we fhall find a (tomach and inteftines. which, as in other animals, run from the mouth to the anus. If the infect has been kept long fading, there will be a mucus found in its body, like the white of an egg; but if crufhed after a full meal, the human blood, which it has fucked in, will appear a little darkened by having pailed through the infecVs body. The male and female of thefe animals are plainly diftinguifhable from each other; and the parts of generation are obvious enough. They are often found coupling tail to tail ; and in this ftate are very eafily defiroyed. The female has an ovary filled with eggs, joined to- gether like a bunch of grapes ; each egg being obiong, almolt cylin- drical, inclining to white, and pretty tranfparent. In about two. days after impregnation by the male, fhe depofits her eggs to the num- ber of about an hundred and fifty, in fome convenient place where they are likely to receive no dillurbance. There they continue for fome months ; during which time, neither cold nor heat, neither rnoifture nor fumigation, can in the lead retard their exclufion ; but they come forth active, and ready for mifchief. It is this haidinefs in the fhell that feems to continue the breed ; as the old ones die every •winter, or are eafily defiroyed by any fumigation that is ufed for that purpoie. But the eggs feem incapab'e of defiruction ; even thofe men who make a livelihood by killing thefe naufeous infects, though they can anfwer for the parent, can never be fure of the egg. For this jeafon they ufually pay thofe houfes to which they are called a fecond or a third vifit, and at lali exterminate them by perfeverance. The manner of deltroying them feems rather the effects of afliduity than antidote ; for the men called in upon this occafion, take every wart of the furniture afunder, brufh every part of it with great afliduity, anoint it with a liquid which I take to be a folution of corrofive fubli- niate^ NATURAL HISTORY. 5J riate, and having performed this operation twice or thrice, the vermin are mod ufually deftroyed. Cleanlinefs, therefore, feems to be the beft antidote to remove thefe naufeous infects ; and wherever that is wanting, their increafe feems but a juft puniihment. Indeed, they are fometimes found in inch numbers among old furniture, and neglected chambers, expofed to the i'outh, that, wanting other fuftenance, they devour each other. They are alfo enemies to other vermin, and deftroy fleas very effectually ; fo that we feldom have the double perfecution of different vermin in the fame bed. Of the bug kind Linnaeus reckons up forty. The dpbis or Plant Loufe, has a bended fnout, two horns on the hinder part of the body, four erect wings, and feet proper for walking. Limiaus has fixteen forts, namely, that of the Currant-buih ; that of the Llm-tree ; that of the Elder ; that of the Mapple ; that of the Lime- tree ; that of the Biich ; that of the Pine ; that of the Rofe ; that of the Parfnip ; that cf the Dock ; that of the Carduus Benidictus ; that of Mug- wort ; that of Saw-wort ; that of Chick-weed ; that of the Lily, and that of the Cabbage. The Currant Loufe is about the fize of a common loufe, and of a brownilh- green colour: the legs are green, and the joints of the knees commonly ftand up above the body and are brown ; the feelers are (len- der, ftrait, and have a joint, at which they are bent near the head, and are of a black colour : the hinder part of the bread is blackifh, and the fides of the body are variegated with fmall black fpots ; the wings are erect and whitifh, only they have a few black veins, and two of them are very fmall, but the vent is prominent, and has two briftly appendages lhorter than the wings. This is fufficient to give a fpecimen of their fhape, for as they be- long to particular trees and plants, they may be readily feen thereon when the leaves are in perfection : there are doubtlels many more than thole already mentioned, which belong to particular, trees. The Coccus, fo calied by Linuaus, has the trunk on its bread, and the body is hairy or downy behind. The Coccus of the berry-bearing Ilex, a fort of an oak, is what is known in the druggifts (hops, by the name of Kermes. It appears to be a membranaceous bladder, of the fize of a pea, fmooth, and fhin- ing, and of a brownifh red colour, covered with very fine down or afh-colouied powder, fwelling with reddifh eggs or infects, which be- ing rubbed with the fingers, pour out a crimfon liquor. It is only met with in pretty hot countries, in the months of May and *Jvne. In March there is fir ft perceived a fort of infect lefs than a millet- feed, and of an oblong oval form, only a little narrower towards the tail : the upper part is convex, red, and marked with exceeding minute gol- den lpecks, and a few tranfverie wi inkles. It has fix feet, and two moveable feelers, which almoft equal the length of the body ; it has alfo black eyes, and a double tail of the fame length as the body. It ad- heres to the trunk, branches, and leaves of the tree, and becomes tor- pid and immoveable, fwelling or growing bigger very fenfibly. If at that time its body is beheld with a microfcope, it appears of a crimfon colour, fhining with golden fpecks, and lying in a fort of whitilh down, which in fome places of the back, under and about the belly, riles up b flocks like a fort of neft ; the back riles very high, and is round, and ia 54 NATURAL HISTORY. in the forepart of the body, which is inftead of a head, three protube- rances are perceived, of which the middle is thickifh and roundifh, but thole on the fides more flender and crooked about the middle. In the month of slfril, this infect becomes of the fize and fhape of a pea, and its membrane or fkin is firmer, and the down, which at the beginning lay in bands on the fkin, covers the whole furface like a fort of powder, and then it feems to be no longer an animal, but a bladder full of pale and watery blood. About the middle or end of May, the inner part of the bladder, under the belly of the animalcula, is furnifhed with oval grains, about half the fize of white peppy feeds, of a pale reddifh colour, fpeckled with gold ; they confift of a thin, white, tranfparent fkin, full of a pale reddifh liquor: they are about two thoufand in number on each bladder, and the eggs of the former infect, which being fhaked off, becomes exactly the lame as thofe that run about the branches and leaves of the Ilex. In the following fpring, they fix themfelves in the divifions of the trunk and branches, where they afterwards lay their eggs. When this in- fect has attained its proper fize, the fkin of the belly or lower part, is pulled up towards the back, leaving a vacant fpace between the belly and the down, infomuch that they have the appearance of Hog-lice half rolled up. It is in this fpace that they lay their eggs, which done the animal dies, and is dried up. They live upon the juice of the leaves, which they fuck in with the fnouts or trunks. They are of two fexes, and the females have been hitherto defcribed but the males are very diftinct from the former, and are a fort of fmall flies like gnats, with fix feet, of which the four forward are fhort, and the two backward long, divided into four joints, and armed with three crooked nails : there aie two feelers on the head a line and a half long, which are moveable, flreaked, and articulated : the tail at the back part of the body is half a line long, and foiked : the whole body is co- vered with two tranfparent wings, and they leap about in the manner of fleas. The harvell of the Kermes is greater or lefs, in proportion to the feverity of the winter ; and the women gather them before fun- rifing, tearing them off with their nails ; for fear there fhould be any lofs from the hatching of the infects, they fprinkle them with viuegar, and lay them in the fun to dry, where they acquire a red colour. There is another fort of Kermes mentioned by other authors, which the country people call worms, and which as they affirm, lay whitilh eggs, from which proceed infects of the fame colour, full of filver fpecks. It feems to be an infect of the fame fpecies as the former, little differing from the red Kermes. There is another blackilh Kermes, found near Leghorn in Tufcanyt upon the dwarf Ilex, like the red kind, only when it comes to maturi- ty, it is full of a whitifh liquor, and eggs ; from thefe a fort of infects proceed, not unlike the true Kermes, but whitifh. Hence it appears there are feveral kinds of Kermes, which only differ in colour; but the red only is ufed in medicine, and for dying. Doctor Lifter has found an infect analogous to this, on the twigs of the cherry, and other trees j for it cannot be faid to be the fame. Cochineal, or the grains of the Indian fig, as they appear in our (hops, when brought from America, are of an irregular fhape, convex on one Gde, and a little concave on the other \ but are both marked with tranf- verfe NATURAL HISTORY. 5S verfe ftreaks or wrinkles : they are of a fcarlet colour within, and with- out of a blackilh red, and fometimes of a white reddifh a(h colour, which are accounted the beft, and they are brought to us from Mexico* They have been a long while taken for fruit, but they are now known to be infects adhering to the prickly pear-tree or fhrub. The Cochineal fnfecl, is of an oval form, of the fize of a fmall pea, with fix feet, and a fhout or trunk, and brings forth its young alive, and is nourished by fucking the juice of the plant. Its body confifts of feveral rings, and when it is once fixed on the plant, it continues im- moveable, being fubject to no change. Some pretend there are two forts, the one domeftic, which is bell, and the other wild, that is of a vivid colour, however they appear to be the fame, only with this dif- ference ; that the wild feed upon cultivated trees, without any affift- ance ; whereas the domeftic are carefully at a ftated feafon, removed to cultivated trees, where they feed upon a purer juice. Thofe who take care of thefe infects, place them on the prickly pear- plant, in a certain order, and are very induftrious in defending them from other infects ; for if any other kind come among them, they take care to brulh- them off with foxes tails. Towards the end of the year, when the rains and cold weather are coming on, which are fatal to thefe infers, they take off the leaves or branches covered with cochineal, that have not attained their utmoft degree of perfection, and keep them in their houfes till the winter is paft. Thefe leaves are very thick and juicy, and fupply them with fufficient nourifhment, while they remain within doors. When the milder weather returns, and thefe animals are about to exclude their ■ young, the natives make them nefts, like thofe of birds, but lefs, of tree-mofs, or foft hay, or the down of cocoa-nuts, placing twelve in every neft. Thefe they fix on the thorns of the prickly pear-plant, and in three or four days time, they bring forth their young, which leave their nefts in a few days, and creep upon the branches of the plant, til! they find a proper place to reft in taking their nourifl:ment ; and when- the females are fecundated by the males, they produce a new offspring p fo that they have a harveft, as it were thrice a year. When the native Americans have gathered the cochineal, they puE them into holes in the ground, where they kill them with boiling water, and afterwards dry them in the fun, or in an oven, or lay them upon hot plates. From the various methods of killing them, arife the dif- ferent colours which they appear in when brought to us. While they are living, they feem to be fprinkled over with a white powder, which" they lofe as foon as the boiling water is poured upon them. Thofe that are dried upon hot places, are the blacked. What we call cochi- neal, are only the females ; for the males are a fort of fly, as in the Kermes. They are ufed both for dying, and in medicine, and are laid to have much the fame virtue as the Kermes ; though they are now feldom ufed alone, but are mixed with other things, for the fake of the colour. The Polijh Scarlet Grain, is, when full grown, of the Cv/.e cf a final! pepper-corn, and is of a roundilh fhape, there being but little iign of an animal. It fticks to the root of the tree on which it feeds, and is of a deep purple colour, tinged with blue. It lies in a rough cup, ibme- what refcmbling that of au acorn, when they are gathered for ufe» The-? 55 NATURAL HISTORY. They feem to be excrefcences upon the root where they produce thek young, which at firft are evidently real infects, having fmall, and fome- what longilh flattifh bodies, which confilt of feveral fegrnents ; and they have fix legs, which are lhort and {lender, and two fine feelers : they are alfo of a purple colour, but not fo deep as that of the parent.' When thefe are grown to their full fi/.e, they fix themfelves to the root of the plant, and appear as above defcribed : the young ones are brecf in the cafe or (kins of the old ones, after they are dead : the male is a flie with two wings, as in the kinds already mentioned. The Pol'ijh Cochineal is a fort of Kermes found at the roots of the tree called Polonian knawel, which are full of a purple juice, and worms of the fame colour : this plant is very common in the Ukrain, efpecially in the moft defart places. The Armenians and the Turks dye the wool, filk, and hair therewith, as well as the manes and tails of their horfes. Thefe infects are placed by Linnaus in the number of thofe with hair wings, that have the mouth placed in the breaft, and the belly hairy below ; however it is only the male that has wings. The Gall InfeSs are bred in a fort of bodies, adhering to a kind of oak in Afia, which differ with regard to their colour, fi'ze, roughnefs,' fmoothiwfs, and fhape, and which we call galls: they are not fruit as fome have imagined, but preternatural tumors, owing to the wounds' given to the buds, leaves, and twigs of the tree, by a kind of infects wherein they breed and lay their eggs. When the Galls are ripe and opened while frefh, a fort of worms are found therein, fometimes one, and fometimes more, near the center in cells, which after fome time turn to flies : they make themfelves a paffage out, by eating the fub- ftance of the gall, and making a round hole therein, they get abroad and fly away. However we do not meet with any author that has given a minute defcription of them. The green flove Bug is a fmall infect of an oval flat fhape, which firmly adheres to the bark or leaves of trees : the back is a little pro- minent, and its belly hollowed ; and the forepart is blunt, but that be- hind forked. It appears in a kind of fhell or covering, which inclofes' the body of the infect ; it has fix very (lender legs, and the eyes fmall and black, and the feelers very {lender. It is of a greenifh colour, and can thruft out its legs at pleafure, fometimes moving about though flowly ; however it generally adheres to the leaf of the tree, continuing in the fame place, and fucking out the juice. The male is a fmall flie, and not nearly fo big as the female, having a {lender oblong body, and long legs : the feelers are fhort, and the wings white. The female is common here in England, on the oiange and lemon trees preferved in ftoves in green-houfes ; and is probably the fame which Linnaus calls the Coccus of the citron tree, or the fhielded Loufe. The water Coccus has a body of an oval figure, rounded on the back, and flat on the belly ; and its colour is brown. It thrufts out a fort of white hairy beard from its hinder part, which is cloven in two, and near it there is placed a blunt tubercle, and towards the other extremity another that is blunt. It is common on the leaves of water-plants, and fhews its legs but very feldom, which are (lender, and fomewhat downy. The male is a fmall flie, with filky whitifh wings, fpotted with brown. ..■> «. .•• . NATURAL HISTORY. 57 The Coccus of the birch tree, is larger than the former, and has an bblong body, fomewhat downy, which is compofed of feveral rings or joints. It is of a deep dufky olive- colour, with fhort legs, and very (len- der feelers- It is common on feveral tiees in woods, where it fixes to the divifion of the branches. The male is a little fiie with dufky brown •wings. The Coccus of infects is very fmall, and is found on the bodies of the larger kind of Beetles, where it is fixed almoft during its whole life : the body is of an oval fhape, with a (harp edge; and is fomewhat con- vex, and of a reddifh brown colour : the furiace of the whole body is fmooth, but not gloily, and the legs are very ihort, as well as the feel- ers, which are fcarce vifible. Befides thefe LinnaUs has the Coccus of the common Moufe-ear ; that of Canary-grafs ; and that of the Birch tree ; and there are probably other kinds not yet difcovered. The 'T/jrips, fo called by Linmsus, has little or no fnout, and the bo- dy is of a linear fhape, with four ftrait wings lying on the back. The Thrips with blueiih wings and a black body, is not fo big as a flea, and its wings mull confequently be fmall and delicate : it has fir legs, two near the neck, and four on the bread; the feelers are flender* black, and confill of fix joints, the external wings are of a greyifh co- lour, and hairy at the extremities, and at the edges. It flies very fel- dom, but runs very fwiftly, twifting its body into various fhapes. The black bodied 'Thrips, is about the fize of a Loufe, and has an oblong {lender body: the external wings are very beautiiu1, variegated with nine alternate tranfverfe llreaks of black and white, there being three of each colour : it is found en the flowers of the larger hawk- tveeds, and runs very fwift, but feldom flies. The Thrips with a brown body, and fnow white wings, is of the fame fize as the former : its brown appearance is owing to the wings, for the colour of the body is coal black : the legs are fhort, and the feelers very flender, conlilling of five joints : it is fometimes found on the Bermudas cedars, which are planted in our gardens. CHAP. IV. ®F 1NSSECTS WITH MEMBRANACEOUS WINGS, WHICH ARE FOUR IN NUM- BER, AND RETICULATED WITH VEINS. THE Panorpa, fo called by Linnsus, is the Scorpion Flie : that- taken notice of by Moufet, is about the fize of a common file, and of the colour of honey * only the top joint of the tail is black, and. armed with a double (ting : the wings are like thofe of the Grafidiop- per, and its walk is like that of a crab : that which other authors call a Scorpion Flie, has an oblong roundifh body, and a fmall head, and a hard horny oblong fnout, bending downwards: the feelers are briflly, black, and confift of thirty joints: the back is brown, the fides yellow, and the wings white, with ibme dufky fpots difpofed in tranfverfe rows, H forming 5* NATURAL HISTORY. forming a fort of line: the tail is articulated, and is terminated by s: weapon refembling that of a Scorpion: this is doubtlefs the fame infeft with that of Moufet. Linnaus fays that it has a horny cylindric fnout, and a lhelly tail. The Raph'ulia or (harp-tailed Flie, has a horney flattifh head, and a briftly (harp tail, and is of the fame fize as the Scorpion Flie, pretty much refembling it in (hape : the head" is black, fmooth, and narrow on the hinder part, and the breaft is narrow, rounded, and black; the? feelers are (lender, white, and confift of a great number of joints ; the body is (lender, oblong, and of a brown colour, variegated with tranf- verfe white lines : the wings are thin and membranaceous, being reti- culated, and having each an oblong brown fpot towards the edge. From the hinder part of the body of the female, there grows a long, (harp, (lender, and bended weapon. It is common in the meadows near the waters, in July. The Chryfops or Golden-Eye, by fome called the Stinking Flie, is a yery beautiful infedt, and is about three quarters of an inch in length? its body is very (lender,, and of a greenifh yellow colour; the wings are very large and tranfparent, except the larger ribs or fibres that are of a fine green, which are pretty numerous : the eyes are very large, and have the appearance of gold ; but when this rnfed is crufhed, it fends forth an intolerable (tench, for which reafon it is called the ftinking flie. It is produced from a worm that feeds upon the plant-lice, upon which account it is named the plant-loufe Lion. The Formica Leo, or Ant Lion, is- of the length of the common hogi loufe, but fomewhat broader; and it has a pretty long head, and a roundilh body, which becomes a little narrower towards the tail . the colour is a dirty grey, fpeckled with black, and the body is combed of feveral flat rings, which (lip one upon another: there are fix feet, four of which are fixed to the breaft, and two to the neck: the head is'fmali and flat, and before there are two little fmooth horns or feelers, which are hard, two lines in length, and crooked at the ends. At the bafes of the feelers, there are two fmall black lively eyes, by which it can fee the fmalleft objetf. Other animals have wings or feet, which en- able them to advance towards their prey, but this can only run back- wards, for it would fooner die than take the leaft ftep towards it ; for which reafon the prey moft come to it, or rather into the fnare provid- ed for it ; which is the only means this infect has to live. It chufes a dry and fandy place, at the foot of a wall, or under' feipe (helter, in order to preferve its work from the rain : the dried fand is the moft proper for it, becaufe any other would defeat its la- bour. When it goes about to dig the hole where it takes its prev, it begins to bend its hinder part, which is pointed, and begins to work upon the fand backwards,, making after feveral attempts, a circular furrow, whofe diameter is always equal to the depth of the hole or pit. On tne edge of this firft furrow it digs a fecond, then a third, and afterwards others which are always lefs than thofe preceding ; then it begins to fink deeper and deeper into the fand : which it throws with its horns or feelers towards the edges, and farther marching always bac.cwards m a fpiral line, in proportion as it finks into the fand • tho repeated motions of its head, throw the fand out of the circle, till the pit is quite made. It always defcribes a perfect circle, and traces a fpiraS NATURAL HISTORY. .<$ (Spiral line without compaffes ; and the pit itfelf refembles the infide of a funnel turned upfide down. When this infect is newly hatched, the firft pit it makes is very fmallj but as it grows bigger, it makes them larger, one of which is about two inches and upwards in diameter, and about as much deep: the work being finifhed, it places itfelf in ambufcade, hiding itfelf at the bottom under the fand, in fuch a manner, that its two horns exact- ly embrace the point, which is the bottom and middle of the pit. It then waits for its prey ; and if by misfortune, a hog loufe, an ant, or other infect, begins to walk round the edge of the precipice, which is made (helving on purpofe to make them fall into the trap, which they generally do, the Ant-Lion never fails to feize upon them. When the fall of a few grains of fand gives notice of the approach of its prey, it begins to fhake the bottom of the fand, which never fails to fall down together with the prey. But if die prey is fo nimble, as to run or fly away fpeedily, it fhoots up the fand, which falls down again like hail upon it, and it being blinded and overwhelmed therewith, it is dragged by the motion of the fand to the center of the hole, where it falls be- tween the two feelers or nippers of the enemy, and is foon buried in the fand, where the Ant-Lion feeds upon it. When there remains nothing but the fhell of the body, this infect takes it up with its feelers, and throws it at leaft fix inches from the edge of the pit ; and then it goes to work again to repair the damage that has been done. It is won- derful to confider that this infect will wait patiently for its prey, fome- times a week, or even a month, without ftirring from its place, and confequently without eating. Some of thefe that have been kept in a box with fand, have lived fix months and upwards, without feeding at all. However it muft be owned, that thofe that feed, become much larger, and more ftrong. When the Ant-Lion attains a certain age, in which it is to change into another form, then it leaves off making pits ; but it continues to make furrows in the land, though in an irregular manner, probably with a defign to put itfelf in a fweat ; after which it hides itfelf under the fand. Either the fweat, or a gummy liquor that proceeds from the body, unites the grains of fand, which form a fort of cruft all over it, and then it appears like a ball, half an inch in diameter ; but fo as to leave room enough for the infect to move, but it muft be obierved, that the gummy liquor alfo condenfes into a thread, finer than thofe of the filk-worm, which it firft fixes to one place, then to another, crof- fing and recroffing it in fuch a manner, as to line the infide of its re- treat with a fine filky fluff work, of a pearl colour, extremely delicate, and perfectly beautiful. But though the work is fo curious and com- modious on the infide, without it appears to be nothing but fand, info- much that it cannot eafily be diftinguilhed from that which lies next it, and fo it efcapes the fearch of birdb, that might otherwife prey upon it. This infect continues thus fhut up for fix weeks, or two months, and gradually parts with its eyes, its feelers, its feet, and its fkin ; and all the flough falls to the bottom of the ball like a rag : then there re- mains a Nymph, which has other legs, other feet, and other entrails; as alfo wings which are wrapped up in a fkin, which feems to be nothing elfe but a liquor dried on its outfide, in the fame manner as it hap- pens to all forts of Butterflies. When the members of this new in- H 2 k& 6o NATURAL HISTORY, feet have acquired the necelTary confidence and vigour, it tears its lodging, and breaks through it* wall. For this purpole it has two teeth, like thofe of Grafshoppers, with which it eats through, and en- larges the opening, till it gets quite out. Its body which is turn- ed like a fcrew, takes up no more than the fpace of a quarter of an inch ; but when it is unfolded, it becomes half an inch in length ; then its fore wings likewife unfold, and in two minutes time, be- come longer than the body. In ihort it becomes a large and beau- tiful Flie, laying afide its barbarity, and rapacious difpofnion : it has then a long flender body, or a brown colour, a i'mall head, with large bright eyes, and h>ng, fiender, pale brown legs, with four large reticulated wings : it greatly refembles the Golden Eye in all things, except its colour, which is not quite fo agreeable: it is common in molt parts of Europe; there are other infects akin to this, which only differ in their fize and colour; but the progreis of their metamorphufis has not been defcribed. The Summer Flie has a prominent palate, with two feelers on each fide, which are twice as long as the body, and blueifn-black wings ; the body is oblong, and of a dufky brown ; but his legs, which are flender, are ol a dufky greyilh black. While it is a worm, it may be frequently feen at the bottoms of fmall clear brooks, hid in a cafe of ftraw: and when it turns to a flie, it comes out of the water, and roves over or about the fame dreams : that mentioned by Moufet, has four ■wings, of a brown colour, an oblong body, and two fhort feelers, with a forked tail, or rather with two briftles proceeding from it. How- ever there are a great many others of this kind, which leave fufficient joom for curious enquirers to enlarge the hiftory of thefe infects. Linnem takes notice of feveral kinds of the Water Flies, and he calls the firit, the black Phryganea with white wings, Ureaked and fpeckled with white : this flie has four wings, and is of the fize of the Scorpion Fhe; the wings are longer than the body, white, pointed, and Ureaked with brown veins. It is found in dirty fplalhy paths. 2. The Phryganea or Water Flie, with teifaceous wings,, and nervous itreaks ; the feelers are placed forwards. It is found in the lame pla- ces as the former. 3.

The dufky Phryganea without fpots, is found at Fahlun in Sweden. The Ephemera is a Flie fo called, becaufe it has been faid to live bat a day, which is in fyme fenfe true ; though there are a fort that never enjoy the benefit ol the fun at all ; for they do not come into the world till after the fun is fet, and die before its rifing : they are in general very pretty flies, and might be ranked among Butterflies, on account of their lhape and their wings : thefs laft are fiiorter and broader in proportion, than thofe of the common flies, and have a large bafe ; but they differ from thofe of Butterflies, in not being covered with the duit that renders them opaque ; tor they are very tranfparent, and very thin : they have four wings, the uppermoft of which are much the lar- ger!:. When this infect is at reft, it generally lays its wings one over the other on the back ; and the body is long, being formed of fix lings that are larger at the origin than near the extremity, and fiom this a tail proceeds, that is longer than all the rett ot the flie, and confifts fometimes of three thieadb of an equal length, and fometirnes of two long threads, and one fhcrt. All Ephemeras were at fir ft worms, and then Aurelias ; and under thefe forms they grow very {lowly in the w*ater ; for Sivammerdam thinks that fome of this kind continue three years under the water. Mr Reau- viur has known them that have been two years there, and many that have been one. But when the flies that proceed from thefe worms, come to be inhabitants of the air, they all die almoft immediately, though Mr Reaumur allerts, that fome flies of this name live for feveral Days. The infect that is to become the flie called Ephemera, has fix fcaly legs, fixed on the coiilet, which in fome of thefe kinds is double, or as it were, divided into two parts : the head is triangular, and a little flatted above and below; the eyes, which are placed before, maybe dil- tinguifhed by their largeneis and colour : they are brown in moll of thefe infects, and near the bafe of each, there is a feeler on the inner fide ; the mouth is furniihed with teeth, and the body confiiis of fix rings ; that next the corflet is the largeft, and they grow lefs and lefs i to the end ; and the laft ring is the fhorteft, from which the three threads proceed, which are as long as the whole body. Thefe infects live in different places, for fome have fixed habitations, and fome wander abont : thofe that have fixed habitations, lye in holes on the furface of the earth, under the water of rivers and flow ftrearns. One of thefe feldom leaves its hole, unlefs through neceffi'ty, and then it makes another : thofe that wander about, fometimes fwim, and fome- times creep on bodies that are under the water ; fometimes they hide themfelves among the 1 nines, or under pieces of wood, and at otb .l times become quiet and ilill cu the feme bodies. Among 4t NATURAL HISTORY. Among thofe that do not change their place, there are a fort of tufts on each fide, which fome have taken for fins ; but Mr Reaumur found by the help of a microfcope, that they are the gills of this infect, which, fie affirms to be a real fiffi : the number of the gills is not the fame in different kindb, for Szvammerdam tells us, there are fix on each fide, and Reaumur feven. While thefe infects continue in the flate of worms, th«y are of a fiefli-colour, and the Aurelias, when they have been juft transformed, are the fame ; but when they are ready to become flies, they turn to a pretty ftrong yellow, and the corflet is brown : the Ephemeras of Hol- land appear about St John's day, when clouds of them may be feen ; whereas they do not appear about Paris till the middle of Augujt* Some make their appearance about fix o'clock, that is about two hours before fun-fet, while others are not feen till the fun is juft ready to dis- appear. Though the lives of thefe flies are fo fhort, they have fufficient time to perform the end of their production ; for they are no fooner meta- xnorphofed into flies but they begin to lay their eggs, which fome do in rivers, and others on any fubftance that they meet with ; and they are faid to lay more at a time than any other infect whatever ; for each bunch of eggs is faid to confift of three hundred and fifty, and there are generally two bunches. There are feveral forts of flies, belonging to this clafs, that live fe- deral days, as was before obferved ; one kind of which are in a condi- tion different from all other flies, for they have ftill another cafe or fkin to get rid of: thefe are to be feen in the fields, and in woods dif- tant from any water; but it is more common to find them among thofe that are neareft. Some of thefe may be feen flicking upon walls and trees, and often with the head downwards, without changing place, or having any fenfible motion ; for they wait for the moment when they fhall be diverted of their laft incommodious garment ; but fome- times this does not happen till twenty-four hours are expired. L.innaus places them among flies that have nervous wings, and takes notice of fix different forts. The firft kind of Ephemera has wings fpotted with brown, the tail confiding of three threads ; and this is found near lakes. 2. The fecond has white wings that are ftreaked, and has a forked tail. It is called in the tranfactions of Upfal, the Ephemera with wings of a whitifh fiefh -colour : they are feen fluttering in f warms by the fides of waters. 3. The Ephemera with white ftreaked wings, may be diftinguifhed from all others of this kind, by that mark only. 4. The brown Ephemera with a tail confifting of two threads, with white wings. 5. The Ephemera with white wings, having a thick Jjlackifh edge, and a tail confifting of two threads. It is called in the Upfal tranfae- tions, the leaft Ephemera with white wings. 6. The. black Ephemera with white lower wings. The Ephemera with white reticulated wings, and two hairs at the tail, is a pretty large flic, with an oblong flender whitiih body, except to* wards the tail, where it is brown : the head is fmall, and on its top £here are two prominences, which have the appearance of eyes, but 3T?

Sy ire really placed above them : the bread is compreffed, and the two- hairs of the tail are twice as long as the body ; and between them there are two fhort crooked ones ; the legs are white as fnow, but thofe before are longer than the reft. It is commonly feen flying over waters in the fummer months. The Ephemera with ftreaked wings, is a fmall flie, with an oblong Sender brownifh body, and a blunt tail without hairs : the wings are large, white, and ftreaked, and fo formed, as to appear like net-work ; there are two prominent tubercles on the head that are fmaller than the eyes, and the male has a black breaft, and a tranfparent body ; but that of the female is of a reddifh brown. The brown Ephemera is about the fize of a Gnat, and has an oblong: flender body, and of a dufky brown, with a black breaft, and long and {lender legs .- the wings are large and tranfparent, and fomewhat of s, whitifh colour; and the tubercles above the eyes are very large, being ef a deep blueifh black ; there are alfo two hairs at the tail, which are as long as the body. The Liiellula, fo called by ~L.inn.itus, is a fort of water flie, for which, reafon they are called water Nymphs by the Germans, and fometimes Dragon Flies. The blueifh green bodied Ubcllula is a beautiful infect, and has a body almoft an inch in length, which is of a fine green, with a blueifh caft ; the head is large, as well as the eyes, whieh are prominent; and the legs are flender and black : the wings are brownifh, with a yellowifh tincture, and have each an oblong white fpot near the edge : the male has a blue body, and blueifh wings, and is commonly feen flying over waters. The red bodied \jlelhla has a body nearly as long as the formeT j but it is more flender, and of a bright red colour, with a large head, and large prominent eyes : the legs are flender, and there are fame: black lines near the fegments of the belly ; but the wings are pellucid and brownifh, and have each a brown fpot near the edge. It is com- mon about fifh-ponds. The \jbellula with a double fpot on the edge of each wing, is near an inch and a half long, and confiderably thick ; but it is larger at the two extremities than in the middle : the breaft is thick, of a greyifh colour, and hairy on the upper part ; the wings are yellowith towards the bafe, and whitifh elfewhere, except the double fpots, which are of a dufky brown : the body itfelf is of a fhining green, and a little hairy on the fides, and the tail has two appendages. It is common about rivers. 'Linnaus likewife divides thefe infects into the middle fized, die fmall, and the great. i. The firft of the middle fized is called by the author the Utlellula ■with a filky fhining body, and wings of a yellowifh dufky colour. It is termed by Ray the middle fized Libella with a blueifh green body, and dun wings without fpots. It frequents the fides of rivers, and the colour is blue, inclining a little to black; the wings are of a yellowifh brown, without any fpeck on the external edges of the wings, which all other kinds are marked with, except the two following. z.

IF we take a curfory view of infects in general, Caterpillars alone,, and the Butterflies and Moths they give birth to, will make a third part of the number. Wherever we move, wherever we turn, thefe infects, in one fhape or another, prefent themfelves to our view. Some, in every ftate, offer the moft entertaining fpectacle ; others are beauti- ful only in their winged form. Many perfons, have an invincible aver- fion to caterpillars, and worms of every fpecies : there is fomething difagreeable in their flow crawling motion, for which the variety of their colouring can never compenfate. But others feel no repugnance at ob- ferving, and even handling them with the moft attentive application. There is nothing in the butterfly ftate fo beautiful or fplendid as thefe infects. They ferve, not lefs than the birds themfelves, to baniih i'olitude from our walks, and to fill up our idle intervals with the molt pleafmg fpeculations. The butterfly makes one of the principal orna- ments of oriental poetry ; but, in thofe countries, the infect is larger and more beautiful than with us. The beauties of the fly may therefore very well excite our curiofity 2o examine the reptile. But we are ftill more ftrongly attached to this i tribe,- 45 NATURAL HISTORY. tribe, from the ufefulnefs of one of the number. The filk worm- Is, perhaps, the mod ferviceable of all other animals ; fince, from its la- bours, and the manufacture attending it, near a third part of the world are clothed, adorned, and fupported. Caterpillars may be eafily diftinguilhed from worms or maggots, by the number of their feet ; and by their producing butterflies or moths. When the fan calls up vegetation, and vivifies the various eggs of in- fers, the caterpillars are the firft that are feen, upon almoft every ve- getable and tree, eating its leaves, and preparing for a ftate of greater perfection. They have feet both before and behind ; which not only enable them to move forward by a fort of fteps made by their fore and hinder parts, but alfo to climb up vegetables, and to ftretch themfelves out from the boughs and (talks, to reach their food, at a diftance. All of this clafs have from eight feet at the leaft, to fixteen ; and this may fei ve to diftinguifh them from the worm tribe, that never have fo many. The animal into which they are converted, is always a butterfly or a moth ; and thefe are always diftmguifhed from other flies, by having their wings covered over with a painted duft, which gives them fuch various beauty. The wings of flies are tranfparent, as we fee in the common flefh fly ; while thofe of beetles are hard, like horn : from fuch the wing of a butterfly may be eafily diftinguifhed ; and words would obfcure their differences. From hence it appears, that caterpillars, whether in the reptile ftate, or advanced to their lafl ftate of perfection into butterflies, may eafily be diftinguifhed from all other infects ; being animals peculiarly form- ed, and alfo of a peculiar nature. The tranfmutations they undergo, are alfo more numerous than thofe of any infect hitherto mentioned j and, in confequence, they have been placed in the third order of chan- ges by Swammerdam, who has thrown fuch lights upon this part of natural hiftory. In the fecond order of changes, mentioned before, we faw the grafshopper and the earwig, when excluded from the egg, affume a foim very like that which they were after to preferve ; and feemed arrived at a ftate of perfection, in all refpects, except in not ha- ving wings ; which did not bud forth until they were come to maturity. But the infects of this third order, that we are now about to defcribe, go through a much greater variety of transformations : for, when they are excluded from the egg, they affume the form of a fmall caterpillar, which feeds and grows larger every day, often changing its fkin, but ftill preferving its form. When the animal has come to a certain mag- nitude in this ftate, it difcontinues eating, makes itfelf a covering or hvjk, in which it remains wrapped up, ieemingly without life or mo- tion!; and after having for fome time continued in this ftate, it once more bur (Is its confinement, and comes forth a butterfly. Thus we fee this animal put on no lefs than three different appearances, from the time it i; firft excluded from the egg. It appears a crawling cater- pillar ; thtn an infenfible aurelia, as it is called, without life or motion 5 and laftly, a butterfly, varioufly painted, according to its different kind. Having thus diftinguifhed this clafs of infects from all others, we will fii ft furvey their hiftory in general ; and then enter particularly into the manners and nature of a few of them, which moft deferve our cu- -iofity and attention. Whea^ NATURAL HISTORY. 67 When winter has difrobed the trees of their leaves, Nature then feems to have loft her infects. Ther. are thcufands of different kinds, with and without wings, which, though fwarming at other leaions, then en- tirely difappear. Our fields are re- peopled, when the leaves begin to bud, by the genial influence of fprir.g ; and caterpillars, of various forts, are feen feeding upon the prornife of the year, even before the leaves are completely unfolded. Thofe caterpillars, which we then fee, may ferve to give us a view of the general means which Nature employs to preferve fuch a number of inlects during that feafon, .when they can no longer find fubfiftence. It is known, by united experience, that all thefe animals are hatched from the eggs of butterflies ; and thofe who obferve them more clofely, will find the fly very careful in depofiting its eggs in thofe places where they are likely to be hatched with the greateft fafety and fuccefs. During winter, therefore, the greateft number of caterpillars are in an egg ftate ; and in this lifelefs fituation, brave all the rigours and the humidity of the climate ; and though of- ten expofed to all its changes, ft ill preferve the latent principles of life, which is more fully exerted at the approach of fpring. That fame power that pufhes forth the budding leaf, and the opening flower, im- pels the infect into animation j and Nature at once feems to furnilh the, guelt and the banquet. When the infect has found force to break its fhell, it always finds its favourite aliment provided in abundance be- fore it. But all caterpillars are not fent off from the egg in the beginning of fpring ; for many of them have fubufted during the winter in their aurelia ftate : in which, as we have briefly obferved above, the animal is feemingly deprived of life and motion. In this ftate of infenllbility, many of thefe infects continue during the rigours of winter ; fome en- clofed in a kind of fhell, which they have fpun fcr themfelves at the end of autumn ; fome concealed under the bark of trees ; others in the chinks of old walls ; and many buried under ground. From all thefe, a variety of butterflies are feen to ilfue, in the beginning of fpring ; and adorn the earlieft part of the year with their painted flutterings. Some caterpillars do not make any change whatloever at the ap- proach of winter ; but continue to live in their reptile ftate, through all the feverity of the feafon. Thefe chufe themfelves fome retreat, where they may remain undifturbed for months together ; and there thev con- tinue quite motionlefs, and as infenfible as if they were actually dead. Their conftitution is fuch, that food, at that time, would be ufelefs ; and the cold prevents their making thofe diffipations which require re- floration. In general, caterpillars of this kind are found in great num- bers together, enclofed in one common web, that covers them all, and ferves to protect them from the injuries of the air. Laftly, there are fome of the caterpillar kind, whofe butterflies live all the winter ; and who, having fluttered about fcr fome part of the latter end of autumn, feek for fome retreat during the winter, in order to anfwer the ends of propagation, at the approach of fprir.g. Thefe are often found lifelefs and motionlefs in the hollows of trees, or the clefts of timber; but, by being approached to the fire, they recover life and activity, and feem to anticipate the defires of fpring. In general, however, whether the animal has fubfified in an egg ftate, during the winter j or whether as a butterfly, bred from an au- J z relia4 £* NATURAL HISTORY. relia, in the beginning of fpring ; or a butterfly that has fubfifted du- ring the winter, and lays eggs as foon as the leaves ot plants are (hot forward, the whole fwarms of caterpillars are in motion to fhare the banquet that Nature has provided. There is fcarce a plant that has not its own peculiar infecls ; and fome are known to fupport feveral of different kinds. Of thefe, many are hatched from the egg, at the foot of the tree, and climb up to its leaves for fubfiftence : the eggs of o- thers, have been glued by the parent butterfly to the leaves ; and they are no fooner excluded from the (hell, but they find theinfelves in the midft of plenty. When the caterpillar nrft burfts from the egg, it is fmall and feeble ; its appetites are in proportion to its fize, and it feems to make no great consumption : but as it increafes in magnitude, it improves in its ap- petites ; fo that, in its adult caterpillar ftate, it is the moft ravenous of all animals whatfoeyer. A fingle caterpillar will eat double its own weight of leaves in a day, and yet feems no way disordered by the meal.— What would mankind do, if their oxen or their horfes were fo voracious ! Thefe voracious habits, with its flow crawling motion, but ftill more a flinging like that of nettles, which follows upon handling the greatefl number of them, make thefe infecls not the molt agreeable objects of human curiofity. However, there are many philoibphers who have fpent years in their contemplation ; and who have not only attended to their habits and labours, but minutely examined their ftru&ure and internal conformation. The body of the caterpillar, when anatomically confidered, is found compofed of rings, whole circumference is pretty near circular or oval. They are generally twelve in number, and are membraneous; by which caterpillars may be diftinguifhed from many other infecls, that nearly reftmble them in form. The head of the caterpillar is connected to the nrft ring by the neck; that is generally io fhort and contracted, that it is fcarce vifible. All the covering of the head in caterpillars feems to confift of a (hell ; and they have neither upper nor under jaw, for they are both placed rather vertically, and each jaw aimed with a large thick tooth, which is fingly equal to numbers. With thefe the animals devour their food in fuch amazing quantities ; and with thefe, fome of the kind defend themfelves againft their enemies. Though the mouth be kept fhut, the teeth are always uncovered; and while the infed is in health, they are feldom without employment. What- ever the caterpillar devours, thefe teeth ferve to chop it into fmall pieces, and render the parts of the leaf fit for fwallowing. Many kinds, while they are yet young, eat not only the fucculent part of the leaf, and leave all the fibres untouched ; others, however, attack the whole leaf, and eat it clean away. One may be amufed, for a little time, in ob- ferving the avidity with which they are feen to feed ; fome are feen. eating the whole day; others have their hours of repaft; fome chufe the night others the day. When the caterpillar attacks a leaf, it places it* body in iuch a manner that the edge of the leaf fhall fall between its feet, which keeps it fleady, while the teeth are employed in cutting it; thefe fall upon the leaf, fomewhat in the manner of a pair of garden- er's fheers ; and every model is fwallowed as foon as cut. Some ca- terpillar! NATURAL HISTORY. 69 terpillars feed upon leaves fo very narrow, that they are not hroader than their mouths; in this cafe the animal is feen to devour it from the point, as we would eat a raddifh. As there are various kinds of caterpillars, the number of their feet are various ; lbme having eight, and fome fixteen. Of thefe feet the fix foremoft are covered with a fort of fhining griftle ; and are there- fore called the fhelly legs. The hindmoft feet, whatever be .their num- ber, are fr.ft and flexible, and are called membranaceous. Caterpillars alio, with regard to their external figure, are either fmooth, or hairy. The fkin of the fir ft kind is foft to the touch, or hard, like fhagreen ; the fkin of the latter, is hairy, and as it were thorny ; and generally, if handled, ftings like nettles. Some of them even caufe this Hinging pain, if but approached too nearly. Caterpillars, in general, have fix fmall black fpnts placed on the circumference of the fore ring, and a little to the fide of the head. Three of thefe are larger than the reft, and are convex and tranfparenti thefe Reaumur takes to be the eyes of the caterpillar ; however, molt of thefe reptiles have very little occafion for fight, and feem only to be directed by their feeling. But the parts of the caterpillar's body which mod juftly demand our attention, are the ftigmata, as they are called ; or thofe holes on the fides of its body, through which the animal is fuppofed to breathe. All along this infect's body, on each fide, thefe holes are eafily dif- coverable.- They are eighteen in number, nine on a fide, rather nearer the belly than the back ; a hole for every ring, of which the animal's body is compofed, except the fecond, the third, and the laft. Thefe oval openings may be confidered as fo many mouths, through which the infect breathes ; but with this difference, that as we have but one pair of lungs, the caterpillar has no lefs than eighteen. It requires no great anatomical dexterity to difcover thefe lungs in the larger kind of caterpillars; they appear, at firft view, to be hollow cartilaginous tubes, and of the colour of mother-of-pearl. Thefe tubes are often feen to unite with each other ; fome are perceived to open into the inteftines ; and fome go to different parts of the furface of the body. That thefe vefTels ferve to convey the air, appears evidently, from the famous experiment of Malpighi ; who, by flopping up the mouths of the ftig- mata with oil, quickly fuffocated the animal, which was feen to did convulfed the in If ant after. In order to afcertain his theory, he rub- bed oil upon other parts ot the infect's body, leaving the ftigmata free; and this feemed to have no effect upon the animal's health, but it con- tinued to move and eat as ufual : he rubbed oil on the ftigmata of one fide, and the animal underwent a partial convulfion, but recovered foon after. However it ought to be obferved, that air is not fo ne- ceifary to thefe as to the nobler ranks of animals, fince caterpillars will live in an exhaufted receiver for feveral days together; and though they feem dead at the bottom, yet, when taken out, recover, and refume their former vivacity. If the caterpillar be cut open longitudinally along the back, its in- teftines will be perceived running directly in a ftraight line from the mouth to the anus. They refemble a number of fmall bags opening into each other ; and ftrengthened on both fides by a flefhy cord, bv Which they are united. Thefe infe&s are, upon many occanons, feen t<* 7« NATURAL HISTORY. to cad forth the internal coat of their inteftines with their food, in the charges which they fo frequently undergo. But the inteftines take up but a fmall part of the animal's, body, if compared to the fatty fub- ftance in which they are involved. This fubftance changes its colour ■when the infecYs metamorphofis begins to approach ; and from white it is ufually feen to become yellow. If to thefe parts, we add the ca- terpillar's implements for fpinning, (for all caterpillars fpin at one time or another) we fhall have a rude fketch of this animal's confor- mation : however we fhall referve the defcription of thofe parts, till we come to the hiftory of the filk-worm, where the manner in which thefe infects fpin their webs, will moil properly find place. The life of a caterpillar feems one continued fucceflion of changes ; and it is feen to throw off one fkin only to affume another; which alfo is diverted in its turn : and thus for eight or ten times iucceffively. We mult not, however, confound this changing of the fkin with the great metamorphofis which it is afterwards to undergo. The throw- ing off one fkin, and affuming another, feems, in comparifon, but a flight operation among thefe animals : this is but the work of a day ; the other is the great adventure of their lives. Indeed, this faculty of changing the fkin, is not peculiar to caterpillars only, but is common to all the infect kind; and even to fome animals that claim a higher tank in Nature. We have already feen the lobfter and the crab out- grow- ing their firft fhells, and then burfting from their confinement, in order to affume a covering more roomy and convenient. It is probable that the loufe, the flea, and the fpider, change their covering from the fame neceffity ; and growing too large for the cruft in which they have been for fome time inclofed, burft it for another. This period is pro- bably that of their growth ; for as foon as their new fkin is hardened round them, the animal's growth is neceffarily circumfcribed, while it remains within it. With refpecT: to caterpillars, many of them change their fkins five or fix times in a feafon ; and this covering, when caft off, often feems fo complete, that many might mi (take the empty fkin for the real infect. Among the hairy caterpillars, for in fiance, the call fkin is covered with hair ; the feet, as well griftly as mem- braneous, remain fixed to it ; even the parts which nothing but a mi- crofcope can difcover, are vifible in it ; in fhort, all the parts of the head ; not only the fkull but the teeth. In proportion as the time approaches in which the caterpillar is to caft its old fkin, its colours become more feeble, the fkin feems to wither and grow dry, and in fome meafure refembles a leaf, when it is no longer fupplied with moifture from the flock. At that time, the infect begins to find itfelf under a neceffity of changing ; and it is not effect- ed without violent labour, and perhaps pain. A day or two before the critical hour approaches, the infect ceafes to eat, lofes its ufual ac- tivity, and feems to reft immoveable. It feeks fome place to remain jn fecurity ; ar.d no longer timorous, feems regardlefs even of the touch. It is now and then feen to bend itfelf and elevate its back ; again it ftretches to its utmoft extent ; it fometimes lifts up the head, and then lets it fall again ; it fometimes waves at three or four times from fide to fide, and then remains in quiet. At length, fome of the rings of its body, particularly the firft and fecond, are feen to fwell confiderably, the old fkin diftends and burfts, till, by repeated fwell- ' NATURAL HISTORY. fj trigs and contractions in every ring, the animal difengages itfelf, and! creeps from its inconvenient covering. How laborious foever this operation may be, it is performed in the fpace of a minute ; and the animal, having thrown off its old (kin, feem9 to enjoy new vigour, as well as to have acquired colouring and beauty. Sometimes it happens that it takes a new appearance and colours very different from the old. Thofe that are hairy, {till preferve their cover- ing ; although their ancient fkin feems not to have loft a fingle hair : «very hair appears to have been drawn, like a fword from the fcabbard, However the fact is, that a new crop of hair grows between the old fkin and the new, and probably helps to throw off the external covering. The caterpillar having in this manner continued for feveral days feeding, and at intervals calling its fkin, begins at laft to prepare for its change into an aurelia. It is mod probable that, from the begin* ning, all the parts of the butterfly lay hid in this infedt, in its reptile ftate ; but it required time to bring them to perfection ; and a large quantity of food, to enable the animal to undergo all the changes re- quifite for throwing off thefe fkins, which feemed to clog the butterfly form. However, when the caterpillar has fed fufheiently, and the parts of the future butterfly have formed themfelves beneath its fkin> it is then time for it to make its fir It, great, and principal change into an aurelia, or a cryfalis, as fome have chofen to call it ; duting which, as was obferved, it feems to remain for feveral days, or even months, without life or motion. Preparatory to this important change, the caterpillar moft ufually quits the- plant, or the tree on which it fed ; or at leaft attaches itfelf to the (talk or the ftem, more gladly than the leaves. It forfakes its food, and prepares, by falling, to undergo its tranfmutation. In this period, all the food it has taken is thoroughly digefted ; and it often Toids even the internal membrane which lined its inteftines. Some of this tribe, at this period alfo, are feen entirely to change colour ; and the vivacity of the tints, in all, feems faded. Thofe of them which are capable of fpinning themfelves a web, fet about this operation ; thofe which have already fpun, await the change in the h*ft manner they are able. The web or cone, with which fome cover themfelves, hides the aurelia contained within from the view ; but in others, where it is more tranfparent, the caterpillar, when it has done fpinning, ftrikes into it the claws of the two feet under the tail, and afterwards forces in the tail itfelf, by contracting thofe claws, and violently linking the feet one againft the other. If, however, they be taken from their web at this5 time, they appear in a ftate of great languor ; and, incapable of walk- ing, remain on that fpot where they are placed. In this condition they remain one or two days, preparing to change into an aurelia ; fome- what in the manner they made preparations for changing their fkin. They then appear with their bodies bent into a bow, which they now and then are feen to ftraighten : they make no ufe of their legs ; but if they attempt to change place, do it by the contortions of their body, In proportion as their change into an aurelia approaches, their body becomes more and more bent; while their extenfions and convulfive' contractions become more frequent. The hinder end of the body is; the part which the animal firft difengages from its caterpillar fkin ; that part of the fkin remains empty, while the body is drawn up contracled- 7* NATURAL HISTORY. ly towards the head. In the fame manner they difengage themfervetf from the two fucceeding rings ; fo that the animal is then lodged en» tirely in the fore part of its caterpillar covering : that half which is abandoned, remains flaccid and empty ; while the fore part, on the contrary, is fwollen and dillended. The animal, having thus quitted the hinder part of its fkin, to drive itfelf up into the fore part, (till continues to heave and work as before ; fo that the feu!' is ibon feen to burtl into three pieces, and a longitudinal opening is made in the three firft rings of the body, through which the infect thrufts forth its jiaked body with ftrong efforts. Thus at laft it entirely gets free from its caterpillar fkin, and for ever forfakes its molt odious reptile form. The caterpillar, thus dripped of its fkin for the laft time, is now be- come an aurelia ; in which the parts of the future butterfly are all vi- fible ; but in fo foft a ftate, that the fmalleft touch can difcompofe them. The animal is now become helplefs and motionlefs ; but only- waits for the afliftance of the air to dry up the moifture on its furface, and fupply it with a cruft capable of refilling external injuries. Im- mediately after being (tripped of its caterpillar fkin, it is of a green colour, especially in thofe parts, which are diftended by an extraordi- nary afflux of animal moifture ; but in ten or twelve hours after being thus expofed, its parts harden, the air forms its external covering into a firm cruft, and in about four and twenty hours, the aurelia may be handled without endangering the little animal that is thus left in fo de- fencelefs a iituation. Such is the hiftory of the little pod or cone that is found fo common by every pathway, flicking to nettles, and fome- times mining like polifhed gold. From the beautiful and resplendent colour, with which it is thus fometimes adorned, fome authors have called it a Chryfalis, implying a creature made of gold. Such are the efforts by which thefe little animals prepare for a ftate of perfection ; but their care is ftill greater to provide themfelves a fe- cure retreat, during this feafon of their imbecility. It would feem like erecting themfelves a monument, where they were to reft fecure, until Nature had called them into a new and more improved exiftence. For this purpofe, fome fbin themfelves a cone or web, in which they he fecure till they have arrived at maturity : others, that cannot fpin fo copious a covering, fufpend themfelves by the tail, in fome retreat where they are not likely to meet disturbances. Some mix fand with their gummy and moift webs, and thus make themfelves a fecure ineruftation ; while others, before their change, bury themfelves in the ground, and thus avoid the numerous dangers that might attend them. One would imagine that they were confeious of the precife time of their continu- ance in their aurelia ftate ; fince their little fepulchres, with reipect ta the folidity of the building, are proportioned to fuch duration. Thofe that are to lie in that ftate of exiftence but a few days, make choice of fome tender leaf, which they render (till more pliant by diffufiHg a kind •f glue upon it : the leaf thus gradually curls up, and withering as it enfolds, the infect wraps itfelf within, as in a mantle, till the genial warmth of the fun enables it to ftruggle for new life, and burft from Jts confinement. Others, whofe time of transformation is alfo near at hanu, fallen their tails to a tree, or to the firft worm hole they meet, in a beam, and wait in that defencelefs fituation. Such caterpillars» ta the other hand, are feen to lie feveral months in their aurelia ftate, am NATURAL HISTORY. j5 &« with much greater circumfpection. Moft of them mix their web with fand, and thus make themfelves a ftrong covering : others build in wood, which ferves them in the nature of a coffin. Such as have made the* leaves of willows their favourite food, break the tender twigs of them firft into imall pieces, then pound them as it were to powder ; and, by means of their glutinous (ilk, make a kind of pafte, in which they wrap themfelves up. Many are the forms which thefe animals affume in this helplefs ftate; and it often happens, that the molt- de- formed butterflies iffue from the moft beautiful aurelias. In generalj however, the aurelia takes the rude outline of the parts of the animal which is contained within it ; but as to the various colours which it is feen to affume, they are rather the effect of accident - for the fame fpecies of infect does not at all times affume the fame hue when it becomes an aurelia. Tn fome, the beautiful gold colour is at one time found 5 in others, it is wanting. This brilliant hue, which does not fall fhort of the beft gilding, is formed in the fame manner in which we fee leather obtain a gold colour, though none of that me- tal ever enters into the tincture. It is only formed by a beautiful brown varnifh, laid upon a white ground ; and the white thus gleam- ing through the tranfparency of the brown, gives a charming golden yellow. fhefe two colours are found, one over the other, in the au- relia of the little animal we are defcribing ; and the whole appears gild- ed, without any real gilding. The aurelia thus formed, and left to time to expand into a butterfly in fome meafure refembles an animal in an egg, that is to wait for ex- ternal warmth to hatch it into life and vigour. As the quantity of moifture that is enclofed within the covering of the aurelia, continues to keep its body in the moft tender ftate, fo it is requifite that this hu- midity fhould be dried away, before the little butterfly can burft its prifon. Many have been the experiments to prove that Nature may in this refpect be affifted by art ; and that the life of the infect may be re- tarded or quickened, without doing it the fmalleft injury. For this purpofe, it is only requifite to continue the infect in its aurelia ftate, by preventing the evaporation of its humidity ; which will confequently add fome days, nay weeks, to its life : on the other hand, by eva- porating its moifture, in a warm fituation, the animal affumes its winged ftate before its ufual time, and goes through the offices atfigned its exiftence. To prove this, Mr Reaumur enclofed the aurelia in a glafs tube ; and found the evaporated water, which exhaled from the body of the infect, collected in drops at the bottom of the tube : he covered the aurelia with varnifh ; and this making the evaporation more difficult and flow, the butterfly was two months longer than its natural term, in coming out of its cafe : he found, on the other hand, that by laying the animal in a warm room, he haftened the difclofure of the butterfly j and by keeping it in an ice-houfe in the fame manner, he delayed it. Warmth acted, in this cafe, in a double capacity ; in- vigorating the animal, and evaporating the moifture. The aurelia, though it bears a different external appearance, never- thelefs contains within it all the parts of the butterfly in perfect forma- tion ; and lying each in a very orderly manner, though in the fmalleft; compafs. Thefe, however, are fo faft and tender, that it is fmpoffible to vifit without difcompoflng them. When either by warmth, or in- K creaftngj 74 NATURAL HISTORY. creafmg vigour, the parts have acquired the neceiTary force and folidt- ty, the butterfly then feeks to difembarrafs itfelf of thofe bar.ds which kept it lb long in confinement. Some infers continue under the form of an aurelia not above ten days ; fome twenty ; fome feveral months ; and even for a year together. The butterfly, however, does not continue fo long under the form of an aurelia, as one would he apt to imagine. In general, thofe ca- terpillars that provide themfelves with cones, continue within them but . a few days after the cone is completely finilhed. Some, however, re- main buried in this artificial covering for eight or nine months, with- .out taking the fmalleft fuifenance dining the whole time : and chough in the caterpillar ftate no animals were fo voracious, when thus trans- formed, they appear a miracle of abllinence. In all, fooner or later, the butterfly burlls from it* prifon ; not only that natural prifon which 4s formed by the ikin of the aurelia, but alfo from that artificial one of filk, or any other fubftance in which it has enclofed itfelf. The efforts which the butterfly makes to get free from its aurelia ftate, are by no means fo violent as thofe which the infecl had in chan- ging from the caterpillar into the aurelia. The quantity of moifture furrounding the butteifly is by no means fo great as that attending its former change; and the ihell of the aurelia is fo dry, that it may be .cracked between the fingers. If the animal be fhut up within a cone, the butterfly always gets ricl of the natural internal ikin of the aurelia, before it eats its way through •the external covering which its own induftry has formed round it. In order to obferve the manner in which it thus gets rid of the aurelia covering, we muir. cut open the cone, and then we ihall have an oppor- tunity of difcovering the infect's efforts to emancipate itfelf from its natural fhell. When this operation begins, there feems to be a violent agitation in the humours contained within the little animal's body. Its fluids feem driven, by an hafty fermentation, through all the veffels ; while it labours violently with its legs, and makes feveral other violent ftru^gles to get free. As all the fe motions concur with the growth of the infecVs wings and body, it is impofllble that the brittle flan which covers it fliould longer refift : it at length gives way, by burlting into four diftincl and regular pieces. The fkin of the head and legs firli feparates ; then the Ikin at the back flies open, and dividing into two regular portions, difengages the back and wings : then there likewife happens another rupture in that portion which covered the rings of the back of the aurelia. After irhis, the butterfly, as if fatigued with its ftruggles, remains very quiet for fome time, with its wings pointed downwards, and its legs fixed in the ikin which it had juit thrown off. At firft fight the animal, juft fet free, and permitted the future ufe of its wings, feems to want them entirely : they take up fuch little room, that one would wonder where they were hidden. But foon after, they expand fo rapidly, that the eye can fcarce actend their unfolding. From reaching fcarce half the length of the body, they acquire, in a mo A wonderful manner, their full extent and bignefs, fo as to be each five times larger than they were before. Nor is it the wings alone that are .thus increafed : all their fpots and paintings, before fo minute as to be fcarce difcernible, are proportionably extended ; fo that, what a few minutes before feemed only a number of confufed, unmeaning points5 NATURAL HISTORY. ~r points, now become diftindt and mod beautiful ornament?. Nor are the wings, when they are thus expanded, unfolded in the manner in which earwigs and grafshoppers difplay theirs, who unfurl them like a lady's fan: on the contrary, thole of butterflies actually grow to their natural fize in this very fhort fpace. The wing, at the inftant it is freed from its late confinement, is confiderably thicker than afterward*; ; fo that it fpreads in all its dimenfions, growing thinner as it becoa.es broader. If one of the wings be plucked from the animal juft fet free, it may be fpread by the fingers, and it will foon become as broad as the other, which has been left behind. As 'the wings extend them- felves fo fuddenly, they have not yet had time to dry ; and accordingly appear like pieces of wet paper, foft, and full of wrinkles. In about half an hour, they are perfectly dry, their wrinkles entirely difappear, and the little animal afiumes all its fplendour. The tranfmutation be- ing thus perfectly finifhed, the butterfly difcharges three or four drops of a blood-coloured liquid, which are the la ft remains of its fuperfluous moifture. Thofe aurelias which are enclofed within a cone, find their exit more difficult, as they have ftill another prifon to break through : this, however, they perform in a fhort time ; for the butterfly, freed from its aurelia fkin, butts with its head violently againft the walls of its artificial prifon ; and probably with its eyes, that are rough and like a file, it rubs the internal furface away ; till it is at laft feen burfting its way into open light ; and, in lefs than a quarter of an hour, the animal acquires its full perfection. Thus, to ufe the words of Swammerdam, we fee a little infignifi- cant creature diftinguifhed, in its laft birth, with qualifications and or- naments, which man, during his ftay upon earth, can never even hope to acquire. The butterfly, to enjoy life, needs no other food but the dews of Heaven ; and the honeyed juices which are diftilled from every flower. The pageantry of princes cannot equal the ornaments with which it is invefted ; nor the rich colouring that embellifhes its wings. The ikies are the butterfly's proper habitation, and the air its element: whiift man comes into the world naked, and often roves about without habitation or fhelter ; expofed, on one hand, to the heat of the fun; and, on the other, to the damps and exhalations of the earth ; both alike enemies of his happinefs and exiftence. — A ftrong proof that, while this little animal is railed to its greatelt height, we are as yet, in this world, only candidates for perfection ! It has been already fnewn that all Butterflies are bred from caterpil- lars ; and we have exhibited the various circumftances of that furprifmg change. It has been remarked, that butterflies may be eafily diftin- guifhed from flies of every other kind, by their wings ; for, in others, they are either tranfparent, like gauze, as we fee in the common flefh fly ; or they are hard and crufted, as we fee the wings of the beetle. But in the butterfly, the wings are foft, opake, and painted over with a beautiful dull, that comes off with handling. The number of thefe beautiful animals is very great ; and though Linr.asus has reckoned up above feven hundred and iixty different kinds, the catalogue is ftill very incomplete. Every collector of butterflies can fhew undefcribed fpecies : and fuch'as are fond of minute difcovery, can here produce animals that have been examined only by himfelf. ' in general, however, thofe of the warm climates, are larger and more K 2 beautiful 76 NATURAL HISTORY. beautiful than fuch as are bred at home ; and we can eafily admit tha beauty of the butterfly, fince we are thus freed from the damage of the caterpillar. It has been the amufement of fome to collect thefe animals, i'rom different parts of the world ; or to breed them from caterpillars at home. Thefe they arrange in fyftematic order ; or difpofe fo as to make ftriking and agreeable pictures ; and all muft grant, that this fpecious idler.eis is far preferable to that unhappy Slate which is pro- duced by a total want of employment. The wings of butterflies, as was obferved, fully diftinguifh them from flies of every other kind. They are four in number; and though two of them be cut off, the animal can fly with the two others remain- ing. They are, in their own fubftance, tranfparent; but owe their opa- city to the beautiful duft with which they are covered ; and which has been likened, by fome naturalifts, to the feathers of birds ; by others, to the Scales of fillies ; as their imaginations were difpofed to catch the reiemblance. In fael, if we regard the wing of a butterfly with a good micr' fcope, we fhall perceive it ftudded over with a variety ot little grains of different dimensions and forms, generally Supported upon a loot ftalk, regularly laid upon the whole fur face. Nothing can exceed the beautiful and regular arrangement of thefe little fubltances : which thus Serve to paint the butterfly's wing, like the tiles of an houfe. Thofe of one rank are a little covered by thofe that follow : they arc of manv figures : on one part of the wing may be feen a fucceffion of oval ftuds ; on another part, a duller of Studs, each in the form of ari heart: in one place they referable a hand open ; and in another they are long or triangular; while all are interfperfed with taller ftuds, that grow between the reft like mufhrooms upon a ftalk. The wing itfelf is Crmpofed of feveral thick nerves, which render the conftruclion very flrong, though light ; and though it be covered over with thoufands of thefe fcales or ftuds, yet its weight is very little increafed by the num- ber. The animal is with eafe enabled to Support itfelf a long while in air, although its flight be not very graceful. When it defigns to fly to a confiderable diftance, it afcends and defcends alternately ; going ibmetimes to the right, fometimes to the lelt, without any appaient Tenfon. Upon clofer examination, however, it will be found that it fiies thus irregularly in purfuit of its. mate; and as dogs bait and quar- ter the ground in purfuit of their game, So thefe infecls traverfe the air, in queft of their mates whom they can discover at more than a mile's diitance. If we profecute our defcription of the butterfly, the animal may be divided into three parts ; the head, the corfelet, and the body. The body is the hinder part of the butterfly, and is compofed of rings, which are generally concealed under long hair, with which that part of the animal is clnthed. The corfelet is more folid than the reft of the body, becaufe the fore wings, and the legs are fixed therein. The legs are Six in number, although four only are made ufe of by the animal ; the two fore legs being often fo much concealed in the long hair of the body, that it is fometimes difficult to discover them. If ■we examine thele parts internally, we Shall find the fame fet of veffels in the butterfly that we obferved in the caterpillar, but with this great difference, that as the blood, or humours, in the caterpillar, circulated from the tail to the head, they are found, in the butterfly, to take a diixA NATURAL HISTORY. 77 direct contrary courfe, and to circulate from the head to the tail ; fo that the caterpillar may be cnfidered as the embryo animal, in which, as we have formerly feen, the circulation is carried on differently from what it is in animals when excluded. But leaving the other parts of the butterfly, let us turn our atten- tion particularly to the head. The eyes of butterflies have not all the Tame torm ; for in ibme they are large, in others fmall ; in fome they are the larger portion of a fphere, in others they are but a fmall part of it, and jult appearing from the head. In all of them, however, the outward coat has a luftre, in which may be difcovered the various colour: of the rainbow. When examined a little clofely, it will be found to have the appearance of a multiplying glafs ; having a great number of fides, or facets, in the manner of a brilliant cut diamond. In this particular, the eye of the butterfly, and of molt other infects, entirely correfpond ; and Luenhoek pretends, there are above fix thou- fand facets on the cornea of a flea. Thefe animals, therefore, fee not only with great clearneis ; but view every object multiplied in a fur- prifing manner. Puget adapted the cornea of a flea in iuch a polition, as to fee objects through it by the means of a microfcope ; and nothing could exceed the ftrange efs of its reprefentations : a foldier, who was feen through it, appeared like an army of pigmies ; for while it mul- tiplied, it alfo diminilhed the object : the arch of a bridge exhibited a fpectacle more magnificent than human {kill could perform ; the flame of a candle feemed a beautiful illumination. It ftill, however, remains a doubt, whether the infect fees objects fingly, as with one eye ; or whether every facet is itfelf a complete eye, exhibiting its own. object diftinct from all the reft. Butterflies, as well as moft other flying infects, have two inftruments, like horns, on their heads which are commonly called feelers. They differ from the horns of greater animals, in being moveable at their bafe ; and having a great number of joints, by which means the infect is enabled to turn them in every direction. Thofe of butterflies are pla- ced at the top of the head, pretty near the external edge of each eye. What the ufe of thefe inllruments may be, which are thus formed with fo much art, and by a Workman who does nothing without realon, is as yet unknown to man. They may ferve to guard the eye; they may be of ufe to clean it ; or they may be the organ of fome fenle which we are ignorant of: but this is only explaining one difficulty by another. We are not fo ignorant of the ufes of the trunk, which few infects of the butterfly kind are without. This inftrument is placed exactly be- tween the e>es; and when the animal is not employed in feeking its nouriihment, it is rolled up, like a curl. A butterfly, when it is feed- ing, flies round fome flower, and lettles upon it. The trunk is then uncurled, and thrult out either wholly or in part; and is employed in fearching the flower to its very bottom, let it be ever fo deep. This fearch being repeated feven or eight times, the butterfly then pafles to another ; and continues to hover over thofe agreeable to its taite, like a bird over its prey. This trunk confifts of two equal hollow tubesg nicely joined to each other, like the pipes of an organ. Such is the figure and conformation of thefe beautiful infects, that cheer our walks, and give us the earlieft intimations of fummer. But \t is not by day alone that they are feen fluttering wantonly from flower W 3$ NATURAL HISTORY. to flower, as the greareft number of them fly by night, and expand the molt beautiful colouring, at thofe hours when there is no fpectator. This tribe of infects has therefore been divided into Diurnal and Noctur- nal Flies; or, more properly fpeaking, into Butterflies and Moths: the one only flying by day, the other moft ufiially on the wing in the night. they may be ealily diftinguilhed from each other, by their horns or fetors: thofe of the butterfly being clubbed, or knobbed at*, the end ; thofe of the moth, tapering finer and finer toa' point. To exprefs it technically — the feelers of the butterflies are clavated ; thofe •of moths, are filiform. The butterflies, as well as the moths, employ the fhort life affigned them, in a variety of enjoyments. Their whole time is fpent either in l^i carefully fought . after. The eggs are ibmetimcs placed round the tender ihoots of plants, in the form of bracelets, confifting of above two hundred in each, and generally furrounding the (hoot, like a ring upon a finger. Some butterflies fecure their eggs from the injuries of air, by covering them with hair, plucked from their own bodies, as birds fometimes are feen to make their neiis ; fo that their eggs are thus kept warm, and alio entirely concealed. All the tribe of fern ale moths lay their eggs a fliort time after they leave the aurelia ; but there are many butterflies that flutter about the whole fummer, and do not, yfhink of laying, till the winter begins to warn them of their approaching end ; fome even continue the whole winter in hollows of trets, and do not provide for pofterity until the beginning of April, when they leave their retreats, depofit their eggs, and die. Their eggs foon begin to feel the genial influence of the fea- , fon : the little animals burft from them in their caterpillar ltate, to be- come aurelias, and butterflies in their turn; and thus continue the round of Nature. Nature, though it has rendered fome animals furorilingly fruitful,,- yet ever takes care to prevent their too great increafe. One fet of creatures is generally oppofed to another: and thofe are chiefly the molt prolific, that are, from their embecility, incapable of making any effectual defence. The caterpillar has perhaps, of all other animalsr the greatelt number of enemies ; and feems only lo exift, by its fur- prifing fecundity. Some animals devour them by hundreds ; others, more minute, yet more dangerous, mangle them in various ways : fo that, how great foever their numbers may be, their deftroyers are in equal proportion. Indeed, if we coniider the rpifchiefs thefe reptiles are capable of occalioning, and the various damages we fuitain from their infaliable rapacity, it is happy for the other ranks of Nature, that there are thoufands of fifties, birds, and even infects, that live chiefly upon caterpillars, and make them their moft favourite repait. When we defcribed the little birds that live in our gardens, and near our houfes, as deftructive neighbours, fufficient attention was not paid to the fervices which they are frequently found to render us. I;; has been proved, that a Angle fparrow and its mate, that have young . ones, deftroy above three thoufand caterpillars in a week ; not to men- tion feveral butterflies, in which numberlefs caterpillars are destroyed in embryo. It is in puriuit of thefe reptiles that we are favoured with the vifits of many of our moft beautiful fongliers ; that amufe us du- ring their continuance and leave us when the caterpillars diiappear. The maxim which has often been urged againii man, that he, of all other animals;, is the only creature that is an enemy to his own kind, and that the human fpecies only are found to deltroy each other, has been adopted,, by perfons who never confidered the hiftory of infects. Same of the caterpillar kind in particular, that feem fitted only to live upon 96 NATURAL HISTORY. Upon leaves and plants, will, however, eat each other ; and the ftrong- eft will devour the weak, in preference to their vegetable food. That which lives upon the oak, is found to leize any of its companion:., which it conveniently can, by the firft rings, and inflict a deadly wound : it then feafts in tranquillity on its prey, and leaves nothing of the ani- mal but the hufk. But it is not from each other they have mod to fear, as in general they are inoffenfive ; and many of this tribe are found to live in a kind of fociety. Many kinds of flies lay their eggs either upon* or within their bodies ; and as thefe turn into worms, the caterpillar is feen to nou- rifh a fet of intedine enemies within its body, that mull fhortly"be its dedruction : Nature having taught flies, as well as all other animals^ the lured methods of perpetuating their kind. — " Towards the end of Auguft," fays Reaumur, " I perceived a little fly, of a beautiful gold colour, bufily employed in the body of a large carerpillar, of that kind which feeds upon cabbage. I gently feparated that part of the ic &i on which thefe infects were placed, from the reft of the plant, and placed it where 1 might obferve them more at my eafe. The fly wholly taken up by the bufinefs in which it was employed, walked along the caterpillar's body, now and then remaining fixed to a particular fpot* "Upon this occafion, I perceived it every now and then dart a ding, which it carried at the end of its tail, into the caterpillar's body, and then drew it out again, to repeat the fame operation in another place. It was not difficult for me to conjecture the bufinefs which engaged this animal fo earneftly ; its whole aim was to depofit its eggs in the cater- pillar's body ; which was to ferve as a proper retreat fnr bringing them to perfection. The reptile thus rudely treated, feemed to hear ;tll very patiently, only moving a little when ftung too deeply; which, how- ever, the fly feemed entirely to difregard. I took p:irticuhr care to feed this caterpillar ; which feemed to me to continue as voracious and vigorous as any of the reft of this kind. In about ten or twelve days, it changed into an aurelia, which feemed gradually to decline, and died : upon examining its internal parts, the animal was entirely de- voured by worms ; which, however, did not come to perfection, as it is probable they had not enough to fuftain them within." What the French philofopher perceived upon this occafion, is every day to be feen in feveral of the larger kinds of caterpillars, whofe bodies ferve as a neft to various flies, that very carefully depofit their eggs within them. The large cabbage catterpillar is fo fubject to it* injuries that, at certain feafons, it is much eafier to find them with than with- out them. The ichneumon fly, as it is called, particularly infefis thefe reptiles, and prevents their fecundity. This fly is of all others, the mod formidable to infects of various kinds. The fpider, that deltroys the ant, the moth, and the butterfly, yet often falls a prey to the ich- neumon ; who purfues the robber to his retreat, and, defpifing his nets, tears him in pieces, in the very labyrinth he has made. This infect, as redoubtable as the little quadruped that deltroys the crocodile, has received the farjjjj name ; and from its dedruction of the caterpillar tribe, is probably more ferviceable to mankind. This infect, I fay, makes the body of the caterpillar the place for depoliting its> eggs ; to the number of ten, fifteen, or twenty. As they are laid in thofe parts which are not mortal, the reptile ftill continues to live, and to feed* NATURAL HISTORY. 9, jfced, mewing no figns of being incommoded by its new "-uefts. The caterpillar changes its fkin ; and fomeiimes undergoes the great change into an aurelia : but ftill the fatal intruders work within, and fecretly devour its internal fubftance : foon after they are feen burftino- through its fkin, and moving away, in order to fpin themlelves a covering, pre- vious to their own little transformation. It is indeed aftonifhin^ fome- times to fee the number of worms, and thofe pretty large, that thus ittue from the body of a fingle caterpillar, and eat their way through its fkin : but it is more extraordinary ftill, that they mould remain within the body, devouring its entrails, without deftroying its life. The truth is, they feem inftructed by Nature not to devour its vital parts % for they are found to feed only upon that fatty fubftance which com- pofes the largeft part of the caterpillar's body. When this furprifing appearance was firft obferved, it was fuppofed that the animal thus gave birth to a number of flies, different from itfelf ; and that the fame caterpillar fometimes bred an ichneumon, and fometimes a butterfly ; but it was not till after more careful inflection, it was difcovered, that the ichneumon tribe were not the caterpillar's offspring, but its murderers. Having before mentioned the damages inflicted by the caterpillar tribe, we now come to an animal of this kind, that alone compenfates for all the mifchief occafioned by the reft. This little creature, which only works for itfelf, has been made of the utmoft'fervice to man ; and fiirnifhes him with a covering more beautiful than any other animal can fupply. We may declaim indeed againft the luxuries of the times, when filk is fo generally worn ; but were fuch garments to fail, what other arts could fupply their deficiency ? Though filk was anciently brought in fmall quantities to Rome, yet it was fo fcarce as to be fold for its weight in gold ; and was considered as fuch a luxurious refinement in drefs, that it was infamous for a mart to appear in habbits of which filk formed but half the compofition. It was moft probably brought among them from the remoteft parts of the Eaft ; fince it was, at the time of which I am fpeaking, fcarcely known even in Perfia. Nothing can be more remote from the truth, than the manner iff which their hiftorians defcribe the animal by which filk is produced,, Paufanius informs us, that filk came from the country of the Seres, a people of Afiatic Scythia ; in which place an infect, as large as the beetle, but in every other refpect refembling a fpider, was bred up for that purpofe. They take great care, as he affures us, to feed and de- fend it from the weather j as well during the fummer's heat, as the rigours of winter. This infect, he obferves, makes its web with its feet, of which it has eight in number. It is fed, for the fpace of four years, upon a kind of pafte, prepared for it ; and at the beginning of the fifth, it is fupplied with the leaves of the green willow, of which it is particularly fond. It then feeds till it burfts with fat ; after which- they take out. its bowels, which are fpun into the beautiful manufacture fo fcarce and coftly. The real hiftory of this animal was unknown among the Romans till the times of Juftinian; and it is fuppofed, that filkworms were not brought into Europe till the beginning of the twelfth century, when Roger of Sicil) brought workmen in this manufacture from Afia Minor,- »fter his return from his expedition to the Holy Land, and fettled then* 12 NATURAL HISTORY. m Sicily and Calabria. From thefe the other kingdoms of Europe learned this manufacture ; and it is now one of the moft lucrative car- ried on among the fouthern provinces of Europe. The filkworm is now very well known to be a large caterpillar, of a whitiih colour, with twelve feet, and producing a butterfly of the moth kind. The cone on whidi it fpins, is formed for covering it while it continues in the aurelia ftate ; and feveral of thefe, properly wound off, and united together, form thofe ftrong and beautiful threads, which are woven into filk. The feeding thefe worms, the gathering, the winding, the twifting, and the weaving their filk, is one of the princi- pal manufactures of Europe ; and, as our luxuries increafe, feems every day more and more neceffary to human happinefs. There are two methods of breeding fiik-worms ; for they may be left to grow, and remain at liberty upon the trees where they are hatch- ed ; or they may be kept in a place built for that purpofe, and fed every day with frefti leaves. The firft method is ufed in China, Ton- ouin, and other hot countries ; the other is ufed in thofe places where the animal has been artificially propagated, and ft ill continues a ftran- ger. In the warm climates, the iilk worm proceeds from an egg, which has been glued by the parent moth upon proper parts of the mulberry-tree, and which remains in that fituation during the winter. The manner in whidh they are fituated and fixed to the tree, keeps them unaffeded by the influence of the weather ; fo that thofe frofts which are fevere enough to kill the tree, have no power t» injure the filkworm. The infect never proceeds from the egg till Nature has provided it a, fufficient i'upply ; and till the budding leaves are furnifhed, in fufficient abundance, for its fupport. When the leaves are put forth, the worms feem to feel the genial fummons, and burfting fiom their lictle eggs, crawl upon the leaves, where they feed with a moft voracious appetite. Thus they become larger by degrees ; and after fome months feeding, they lay, upon every leaf, fmall bundles, or cones of filk, which ap- pear like fo many golden apples, painted on a fine green ground. Such is the method of breeding them in the Eaft : and without doubt it is beft for the worms, and leaft troublefome for the feeder of them. But it is otherwife in our colder European climates ; the frequent changes of the weather, and the heavy dews of our evenings, render the keep- ing them all night expofed, lubject to fo.many inconveniences, as to admit of no remedy. It is true, that by the afiiftance of nets, they may be preferved from the infults of birds ; but the fevere cold wea- ther, which often fucceeds the firft heats of fummer, as well as the rain and high winds, will deftroy them all ; and, therefore, to breed them in Europe, they mull be iheltered and protected from every external injury. For this purpofe, a room is chofen, with a fouth afpedl; and the windows are fo well glazed, as not to admit the leaft air : the walls are well built, and the planks of the floor exceeding clofe, fo as to ad- mit neither birds nOr mice, nor even fo much as an infect. In the middle theie ihould be four pillars erected, or four wooden pofts, fo •alaced as to form a pretty large fquare. Between thefe are different Itories made with ofier hurdles ; and under each hurdle there fhould be a floor, with an upright border all round. Thefe hurdles and floors aiu;i hang upon pullies, fo as to be placed, or taken down at pleafure. When NATURAL HISTORY. . %$ When the worms are hatched, fome tender mulberry leaves are pro- vided, and placed in the cloth or paper box in which the eggs were laid, and which are large enough to hold a great number. When they have acquired ibme ftrength, they mull; be diftributed on beds of mul- berry leaves, in the different ftories of the fquare in the middle of the room, round which a perfon may freely pafs on every fide. They will fix themfelves to the leaves, and afterwards to the flicks of the hurdles, when the leaves are devoured. They have then a thread-, by which they can fufpend themfelves on occafion, to prevent any fhock by a fall ; but this is by no means to be confidered, as the filk which they fpin afterwards in fuch abundance. Care muft be taken that frelh leaves be brought every morning, which muft be ftrewed very gently and equally over them ; upon which the filk worms will forfake the remainder of the eld leaves, which muft be carefully taken away, and every thing kept very clean ; for nothing hurts thefe infects fo much as znoilture and uncleanlinefs. For this reafon their leaves muft be gathered when the weather is dry, and kept in a dry place, if it be ne- .cefTary to lay in ftore. As thefe animals have but a iiiort time to live, they make ufe of every moment, and almoft continually are fpinning, except at thofe intervals when they change their lkins. If mulberry leaves be difficult to be obtained, the leaves of. lettuce or holyoak will fuftain them ; but they do not thrive fo well upon their new diet; and their filk will neither be fo copious, nor of fo good a quality. Though the judicious choice, and careful management of their diet, is abfolutely neceilary, yet there is another precaution of equal impor- tance, which is to give them air, and open their chamber windows, at fuch times as the fun fhines warmed. The place alfo muft be kept as clean as poflible ; not only the feveral floors that are laid to receive their ordure, but the whole apartments in general. Thefe things well obferved, contribute greatly to their health and increafe. The worm, at the time it burfts the died, is extremely fmall, and of a black colour ; but the head is of a more fhining black than the reft of the body : fome days after, they begin to turn whitifh, or of an afh- coloured grey. After the fkih begins to grow too rigid, or the animal is ftinted within it, the infect throws it off, and appears clothed a-new : it then becomes larger and much whiter, though it has a greenifh caft : after fome days, which are more or lefs, according to the different heat of the climate, or to the quality of the food, it leaves off eating, and feems to deep for two days together : then it begins to ftir, and put itfelf into violent motions, till the fkin fall off the fecond time, and is thrown aflde by the animal's feet. All thefe changes are made in three weeks or a month's time ; after which it begins to feed once more, ftill in its caterpillar form, but a good deal differing from itfelf before its change. In a few days' time it feems to deep again ; and, when it: awakes, it again changes its clothing, and continues feeding as before. When it has thus taken a fufficiency of food, and its parts are difpofed for affuming the aurelia form, the animal forfakes for the laft time, all food and fociety, and prepares itfelf a retreat to defend it from exter- nal injuries, while it is feemingly deprived of life and motion. This retreat is no other than its cone, or ball of filk, which Nature J14S taught it to compoie with great art ; and within which it buries L z itfelf, g4 NATURAL HISTORY. Itfelf, till it affumes its winged form. This cone or ball is fpun from two 'little longifh kinds of bags that lie above the interlines, and are filled with a gummy fluid, of a marigold colour. This is the fubflance of which the threads are formed; and the little animal is furnilhed with a furprifing apparatus for fpinning it to the degree of finenefs which its occafions may require. This inftrument in fome xneafure refembles a wire-drawer's machine, in which gold or filver threads are drawn to any degree of minutenefs ; and through this the animal draws its thread with great affiduity. As every thread proceeds from two gum bags, it is probable that each fupplies its own ; which, however, are united, as they proceed from the animal's body. If we examine the thread with a microfcope, it will be found that it is flatted on one fide, and groved along its length : from hence we may infer, that it is doubled juft upon leaving the body; and that the two threads flick to each other by that gummy quality of which they are poileffed. Previous to fpinning its web, the filkworm feeks out fome convenient place to erect its cell, without any obftruction. When it has found a leaf, or a chink fitted to its purpofe, it begins to wreathe its head in every direction, and fattens its thread on every fide to the fides of its retreat. Though all its firft eiTays feem perfectly confuted, yet they are not altogether without defign : there appears indeed, no order or contrivance in the difpofal of its firft threads ; they are by no means laid artfully over each other, but are thrown out at random, to fervp as an external flielter againft rain ; for Nature having appointed the animal to work upon trees in the open air, its habits remain, though it is brought up in a warm apartment. Malphigi pretends to have obferved fix different layers in a fingle cone of filk: but what eafily may be obferved is, that it is compofed exter- nally of a kind of rough cotton-like fubftance, which is called flofs ; within the thread is more diftinct and even ; and next the body of the aurelia., the apartment feems lined with a fubflance of the hardnefs of paper, but of a much ftronger confidence. It muft not be fuppofed, that the thread which goes to compofe the cone, is rolled round, as we roll a. bottom ; on the contrary, it lies upon it in a very irregular manner, and winds off now from one fide of the cone, and then from the other. This whole thread, if meafured, will be found about three hundred yards long ; and fo very fine, that eight or ten of them are generally rolled off into one by the manufacturers. The cone, when completed, is in form like a pigeon's egg, and more pointed at one end than the other ; at the fmaller end, the head of the aurelia is generally found ; and this is the place that the infect, when converted into a moth, is generally feen to burft through. It is generally a fortnight or three weeks before the aurelia is chan- ged into a moth ; but no fooner is the winged infect completely form- ed, than having divefted itfelf of its aurelia fkin, it prepares to burft through its cone, or outward prifon : for this purpofe it extends its head towards the point of the cone, butts with its eyes, which are rough, againft the lining of its cell, wears it away, and at laft pufhes forward, through a paflage which is fmall at firft, but which enlarges as the animal increases its efforts for emancipation ; while the tattered remnants of its aurelia fkin lie in confufion within the cone, like a bun? die of dirty linen. NATURAL HISTORY. 8$ The animal, when thus fet free from its double confinement, ap- pears exhaufted with fatigue, and feems produced for no other purpoie but to tranfmit a future brood. It neither flies nor eats ; the male only feeking the female, whofe eggs he impregnates ; and their union con- tinues for four days, without interruption. The male dies immediately after feparation from his mate ; and fhe furvives him only till (he has laid her eggs, which are not hatched into worms till the enfuing fpring. However, there are few of thefe animals fuffered to come to a ftate pf maturity ; for as their burfting through the cone deltroys the nlk, the manufacturers take care to kill the aurelia, by expofing it to the fun, before the moth comes to perfection. This done, they take off the fiofs, and throw the cones into warm water, flirring them till the firft thread offers them a clue for winding all off. They generally take eight of the filken threads together; the cones ft ill kept under water, till a proper quantity of the filk is wound off: however, they do not take all ; for the latter parts grow weak, and are of a bad colour. As to the paper-like fubflance which remains, fome ftain it with a variety of colours, to make artificial flowers, others let it lie in the water, till the glutinous matter which cements it is all diifolved : it is then carded like wool, fpun with a wheel, and converted into filk fluffs of an infe- rior kind. CHAP. VI. OF FLY INSECTS WITH FOUR MEMBRANACEOUS WINGS. THE Tenthredo is diftinguifhed from others of this kind, by the female having a ferrated weapon or fting at the tail, and the worm from which it proceeds, has feveral feet. Linnaus diftinguifhes them into that clavated with feelers ; that of the willow- tree ; that of the poplar-tree; that of fig-wort; that of the rofe ; and that of the birds cherry-tree. The black Tenthredo with clavated feelers, is nearly of the fize of a Hornet, and the body is black and hairy, only the third, fourth, and fifth joints, are of an iron-grey. The wings are thin and tranfparent, and the legs black, but the feet are yellow within, and the feelers are yellow, except at the loweft joint, which is black. There are a few dark grey nerves in the wings, and the wings themfelves are of a brown- ifh tincture towards the outer edge. The worm it proceeds from, is fmooth and green, only there is a black lift down the back, edged with yellow ; it has twenty-eight legs, and often rolls itfelf up. The black Tenthredo with feelers that have eleven joints, is of the fize of a common Flie, and the wings have feveral veins ; there are two black fpots, on the uppermoft of which, that neareft the bread, is in the ftiape of a half moon, but the other is round, and near it, to- wards the top, there is one that is white. The yellow- legged Tenthredo is not much larger than a Flea, though the flender feelers are ccxrtpofed of ten joints.

T O give a complete hifiory of this mk& in a few pages, which fome have exhauRed volumes in defctibing, and wh of .na- ture and properties ftill continue in difpute, is impoffible. It will be fufficient to give a general idea of the animal's operations ; which, though thev have been fiudied for more than two thoufand years, are Rul bat incompletely known. The account given us by Reaumur is fufhc.ently minute, and, if true, fufficiently wonderful : but I find many ot the fac.s which he relates, doubted by thofe who are molt converfant with bees ; and fome of them actually declared not to have a real exiRence m nature. It is unhappy, therefore, for thofe whofe method demands an hirtory of bees, that they are unfurnilhed with thofe materials which "J* ™- duced fo many obfervers to contradict fo great a natura hi,. His lite was fpent in the contemplation ; and it requires an equal .hare ot at- tention, to prove the error of his difcoveries. Without entering* there- fore, into the difpute, I will take him for my guide ; and juR mention, as I and is confequently better qualified to refill the moifture of the feafon, and preferve the works warm 2nd dry within. The fine wax is as necei- fary to the animal's prefervation as the honey itfelf. With this they make their lodgings, with this they cover the cells of their young, and in this they lay up their magazines cf honey. This is made, as has been alrea- dy obferved, from the dufl of flowers, which is carefully kneaded by the little infect, then fwallowed, and having undergone a kind of digeltion, is formed into the cells, which anfwers fuch a variety of purpofes. To collect this* the animal rolls itfelf in the flower it would rob, and thus takes up the vegetable duft with the hair of its body. Then carefully bruihing it into a lump, with its fore paws it thrulfs the composition into two cavities behind the thighs, which are made like fpoons to re- ceive the wax, and the hair that lines them, ferves to keep it from falling. As of wax, there are alfo two kinds of honey : The white and the yellow. The white is taken without fire from the honey-combs. The yellow is extracted by heat, and fqueezed through bags, in a prefs. The belt honey is new, thick, and granulated, of a clear tranfparent white colour, of a foft and aromatic fmell, and of a fweet and lively tafte. Honey made in mountainous countries, is preferable to that o'c the valley. The honey made in the fpring, is more highly efteemed, N than £«: NATURAL HISTORY. lhan that gathered in fummer, which lad is ftill more valuable, than5 that of autumn, when the flowers begin to fade and lofe their fra- grance. The bees afe nearly alike in all parts of the world, yet there are differences worthy our notice. In Guadaloupe, the bee is lefs by one half, than the European, and more black and round. They have no fling, and make their cells in hollow trees ; where, if the hole they meet with is too large, they form a fort of waxen houfe, of the fhape of a pear, and in this they lodge and (tore their honey, and lay their eggs. They lay up their honey in waxen veflels, of the fize of a pi- geon's egrr, of a black or deep violet colour : and thefe are fo joined together, that there is no fpace left between them. The honey never congeals, but is fluid, of the confidence of oil, and the colour of am- ber. Refembling thefe, there are are found little black bees, without a fling, in all the tropical climates ; and though thefe countries are re- plete with bees, like our own, yet thofe form the moft ufeful and laborious tribe in that part of the world. The honey they produce, is neither fo unpalatable, nor fo furfeiting as ours ; and the wax is fo loft, that it is only ufed for medicinal purpofes, it being never found hard enough to form into candles, as in Europe. Of infecls, that receive the name of bees, among us, there are fe- veral ; which, however, differ very widely from that induftrious, fa- cial race we have been juft defcribing. The Humble Bee is the lar- geft of all this tribe, being as large as the firft joint of one's middle finger. Thefe are feen in every field, and perched on every flower. They build their nefl in holes in the ground, of dry leaves, mixed with wax and wool, defended with mofs from the weather. Each humble bee makes a feparate cell about the fize of a fmall nutmeg, which is round and hollow, containing the honey in a bag. Several of thefe cells are joined together, in fuch a manner, that the whole appears like a duller of grapes. The females, which have the appearance of wafps, are very few, and their eggs are laid in ceils, which the reft foon cover over with wax. It is uncertain whether jhey have a queen or not; but there is one much larger than the reft, without wings and without hair, and all over black, like poliftied ebony. This goes and views all the works, from time to time, and enters into the cell, as if it wanted to fee whether every thing was done right: In the morning, the young humble bees are very idle, and feem not at all inclined to labour, till one of the largeft, about feven o'clock, thrufts half its bo- dy from a hole, defigned for that purpofe, and feated on the top of the nefl, beats its wings for twenty minutes fucceflively, buzzing the whole time, till the whole colony is put in motion. The humble bees gather honey, as well as the common bees; but it is neither fo fine, nor ib good, nor the wax fo clean, or fo capable of'fufion. Belides the bees already mentioned, there are various kinds among us, that have much the appearance of honey-makers, and yet make only wax. The Wood Bee is feen in every garden. It is rather lar- ger than the common queen bee ; its body of a blueifti black, which is, imooth and ihining. It begins to appear at the approach of fpring, and is feen flying near walls expofed to a funny afpecl. This bee makes its nefl in fome piece of wood, which it contrives to fcoop and hollow for its purpofe. This, however is never done in trees that are Handings NATURAL HISTORY. $9 'ftanding, for the wood it makes choice of is half rotten. The holes are not made directly forward, but turning to one fide, and have au opening iufficient to admit one's middle finger ; from whence runs the inner appartment, generally twelve or fifteen inches long. The inftru- ments ufed in boaring thefe cavities, are their teeth ; the cavity is ufu- ally branched into three or four apartments; and in each of thefe, they lay their eggs, to the number of ten or twelve, each fepafate and diftinct from the reft : The egg is involved in a fort of paite, which ferves at once for the young animal's protection and nourifhment. The grown bees, however, feed upon fmall infects, particularly a loufe, of a reddifh brown colour, of the fize of a fmall pin's head. Mafon Bees make their cells with a fort of mortar, made of earth, which they build againft a wall that is expofed to die fun. The mor- tar, which at firft is foft, foon becomes as hard as ftone, and in this their eggs are laid. Each neft contains feven or eight cells, an egg in every cell, placed regularly one over the other. If the neft remains unhurt, or wants but little repairs they make ufe of them the year en- fuing: and thus they often ferve three or four years fucceflively. From the ftrength of their houfes, one would think thefe bees in perfect fecu- rity, yet none are more expofed than they. A worm with very ftrong teeth, is often found to bore into their little fortifications, and devour their young. The Ground Bee builds its neft in the earth, wherein they make TOund holes, five or fix inches deepj the mouth being narrow, and ■only juft Iufficient to admit the little inhabitant. It is amufing enough, to obferve the patience and afliduity with which they labour. They carry out all the earth, grain by grain, to the mouth of the hole, where it forms a little hillock, an Alps compared to the power of the artift by which it is raifed. Sometimes the walks of a garden are found undermined by their labours; fome of the holes running directly down- ward, others horizontally beneath the furface. They lay up in thefe cavities provifions for their young, which confift of a pafte that has the appearance of corn, and is of a fweetifh tafte. The Le-aj 'cutting Bees make their neft and lay their eggs among bits, of leaves very artificially placed in holes in the earth, of about the length of a tooth-pick cafe. They make the bits of leaves of a round- iih form, and with them line the infide cf their habitations. This ta- peftry is ftill further lined by a reddifh kind of pafte, fomewhat fweet or acid. Thefe bees are of various kinds ; thofe that build their nefts with chefnut leaves are as big as drones, but thofe of the rofe-tree are fmaller than the common bee. The Wall Bees are fo called, becaufe they make their nefts in walls of a kind of iilky membrane with which they fill up the vacuities be- tween the fmall ftones which form the fides of their habitation. Their apartment confifts of feveral cells placed end to end, each in the fhape of a woman's thimble. Though the web which lines this habitation is thick and warm, yet it is transparent and of a whitilh colour. This fiibftance is fuppofed to be fpun from the animal's body. The male and females are of a fize, but the former are without a fting. To thefe varieties of the bee kind might be added feveral others which are all different in nature, of which hereafter. N 2 However ioo NATURAL HISTORY. However fimilar many infects may be in appearance, this does not imply a firnilitude in their hiftory. The bee and the wafp refemble each other very itrongly, yet, in examining their manner and their du- ration, they differ very widely ; the bee labours to lay up honey, and lives to enjoy the fruits of its induftry ; the wafp appears equally affi- duous, but only works for pofterity, as the habitation is fcarcely com- pleted when the inhabitant dies. / The wafp is well known to be a winged infect with a fling. To be longer in proportinn to its bulk than the bee, to be marked with bright yellow circles round its body, and to be the mod fwift and active infect of all the fly kind. On each fide of the mouth this animal is furniihed with a long tooth, notched like a faw, and with thefe it is enable to cut any fubftance, not omitting meat itfelf, and to carry it to its neft. Wafps live like bees in community, and fometimes ten or twelve thou- fand are found inhabiting a Angle neft. Of all other infects the wafp is the moft fierce, voracious, and moft dangerous, when enraged. They are feen wherever flefh is cutting up, goiging themfelves with the fpoil, and then flying to their nefts with their reeking prey. They make war alio on every other fly, and the fpider himfelf dreads their approaches. Every community among bees is compofed of females or queens, drones or males, and neutral or working bees. Wafps have fimilar occupation ; the two firft are for propagating the fpecies, the lalt for nuriing, defending, and fupporting the rifing progeny. Among bees, however, there is ieldom above a queen or two in an hive ; among wafps there are above two or three hundred. As foon as the fummer begins to invigorate the infect tribes, the ■wafps are the moft of the number, and diligently employed either in providing provilions for their neft, if already made, or in making one, if the former habitation be too fmallto receive the increafing community. The neft is one of the moft curious objects in natural hiftory, and contri- ved almoft as artificially as that of the bees themfelves. Their principal care is to feek out an hole that has been begun by fome other animal, a field moufe, a rat, or a mole, to build their nefts in. They fome- thnes build upon the plain, where they are fure of the drynefs of their fituation, but moft commonly on the fide of a bank to avoid the rain or water that would otherwise annoy them. When they have chofen a proper place they go to work with wonderful afliduity. Their firft labour is to enlarge and widen the hole, taking away the earth and carrying it off to fome diftance. They are perfectly formed for labour, being furniihed with a trunk above their mouths, two faws en each fide which play to the right and left againlt each other, and fix ftrong mulcular legs to fupport them. They cut the earth into fmall par- cels with their faws, and carry it out with their legs or paw-s. ihis i* the work oi feme days ; and at length the outline of their habitation is formed, making a cavity of about a foot and an half every way. While fome are working in this manner, others are roving the fields to feek out materials for their building. To prevent the earth from fall- ing down and crufhing their rifing city into ruin, they make a fort of roof with their gluey fubftance, to which they begin to fix the rudiments of their building, working from the top downwards, as if they were hanging a bell, which, however, at length they clofe up at the bot- tom, > NATURAL HISTORY. rot Lorn. The materials with which they build their nefts are bits of wood and glue. The wood the] here they can from the rails and ports which thej meel with in the fields and elfewhere. Thefe they faw and divide iptd i multitude of fmall fibres, of which they take up little bundles in their claws, letting fall upori them a few drops of gluey matter with which their bodies are provided, by the help of which they knead the whole compoiition into a parte, which ferves them in their future building. \\ hen the\ have returned with this to their neft, they (tick their load of parte on that part where they make their walls and partitions ; they tread it clofe with their feet, and trowel it with their trunks, (fill going backwar is ak they work. Having repeated this operation three or four times, the composition is at length flatted out until it becomes a fmall leaf of a grey colour, much finer than paper, and of a pretty firm texture. This done the fame wafp returns to the field to collect a fecond load of parte, repeating the fame feveral times, placing layei upon layer, and ilrengthening every parti- tion in proportion to the wants or convenience of the general fabric. Other working wafps come quickly after to repeat the fame operation laying mere leaves upon the former, till at length, after much toil, they have finifhed the large roof which is to fecure (hem from the tumbling in of the earth. This dome being finifhed, they make another entrance to then habitation, defigned either for letting in the warmth of the fun, or for efcaping in cafe one door be invaded by plunderers. Certain however it is, that by one of ihefe they always enter, by the other they fally forth to their toil ; each hole being fo fmall that they can pafs but one at a time. The walls being thus compofed, and the whole fome- what of the lhape of a pear, the" labour at their cells, which they com- pofe of the fame paper lik: fubftai c thai goes to the formation of the outfide works. Their combs difFei from ihofe of bees, not lefs in the compofition than the pofition which they are always feen to obtain. The honey comb of the bee*, is edgeways with reipect to the hive ; that of the wafp is flat, and the mouth of every cell opens downward. Thus is their habitation, contrived ftory above ftory, fupported by fe- veral rows of pillars which give firmnefs to the whole building, while the upper ftory is flat-robfed, and as fmooth as the pavement of a room, laid with fquares of marble. The wafps can freely walk upon thefe (lo- ries between the pillars to do whatever their wants require. The pil- lars are very hard and compact, being larger at each end than in the middle, not much unlike the columns of a building All the cells of the nelf are only deftined for the reception of the young, being replete with neither wax nor honey. Each cell is like that of the bee, hexagonal ; but they are of two forts, the one larger for the production of the male and female wafps, the other lefs for the reception of the working part of the community'. When the females are impregnated by the males, they lay their eggs, one in each cell, and Itick it in with a kind of gummy matter to prevent its falling out. From this egg proceeds the infect in its worm ftate, of which the old ones are extremely careful, feeding it from time to time till it becomes large, and entirely fills up its cell. But the wafp com- munity differs from that cf the bee in this ; that among the latter the working bees take the parental duties upon them, whereas among the wafps the females alone are permitted to feed their young, and to nurfe In of the (lings of Bees, is not to hurt mankind, but to de- fend them againft their enemies which are very numerous. Hornets and Wafps will tear open the bellies of Bees, to fuck the contents. Spiders alfo are enemies, but they are not able to do fo much harm ; as for Ants, they want nothing but the honey ; but Lizards, Frogs, and Toads, will eat the Bees entirely up, when they can catch them. There is alfo a fort of Moths, that will get into their cells, and will penetrate into a great number of them, to feed upon the wax, of which they are extremely fond. Old Bees are fubjecl to a kind of Lice, which are not found upon the young ; however they do not appear to be greatly molefted by them. Field Mice and Birds, are greater enemies to Bees, than any thing elfe ; infomuch that in one night, when they are benumbed in the winter feafon, a fingle field Moufe is able to de- ilrov a hive that is "very well flocked. Reaumur obferves, that thefe anrfRals generally eat nothing but the heads and the breads. They will ieive Birds much in the fame manner, for the young Larks have been found near the nefts, that have nothing wanting but the head and the neck. It is alfo faid, that among Birds, that thofe called Bee eaters, Swallows, and Titmice, feed greatly upon Bees ; but the Bird that does mod mifchief among them, and deftroys more than all the reft put together, is the Sparrow. They fwallow them like grains of corn, and they have been feen to carry three Bees at a time, to feed their young with, that is one in their bills, and two others in their claws. Thofe that are accuftomed to take care of Bees, may go among them very fafely, provided they do not anger them ; but if they do, they muft expect the reward of their rafhnefs. They generally attempt to fting people in their faces, and when any one is ftung, if the Bee is forced away too foon, it always leaves its fting behind, with its appen- dages ; but then the Bee will live but a fhort time after it. The fting is generally more painful in fummer than in winter ; for this depends upon the quantity of the venom, and the vigour of the Bee : befides there are perfons which are more affected with the flings of Bees than others. Generally fpeaking, the fting is followed with an itching, an inflammation, a fwelling, and a fharp pain ; and if it happens to be near the eyes, the eye-lids will fometimes clofe up for feveral days. Authors that have wrote upon this iubjecl, pretend to give feveral re- medies againft the flinging of Bees ; but Reaumur has tried them all, ■with little fuccefs ; however he thinks that the herb called arfe-mart, has proved better than any thing elfe, when bruifed in a mortar, and applied thereto. But the beft way is to take out the fting as foon as poflible, and then apply a little water, or vinegar, to the wound, as loon as poffible, and then the pain will vanifh ; yet it has been obfer- ved, that it has fometimes returned again, with as much- violence as before. Snme have pretended, that there are certain fmells, which give great offence to Bees ; and that they are fondeft of every thing that is clean and pure ; but this is a miftake, for they always like ltanding dirty NATURAL HISTORY. ,o* dirty water, better than that which is quite limpid. But fmoak will caufe them to get at a diftance from it, and if they cannot readily, it benumbs them, and makes them lye as if they were dead ; this is the method fpme make ufe of, to get part of the honey out of the hive. This operation is performed at different times, in different countries ; but the bed is in the morning, after the Bees have been rendered lefs active by the coldnefs of the night, and then it will be almoft needlefs to fmoak them. However, in a warm feafon, when flowers are plen- ty, they may be made to pafs out of a hive that is full of -wax and ho- ney, into another that is quite empty ; but then the brood will be loft ; that is, the eggs, the nymphs, and the worms ready to be changed into nymphs. When the honey is taken away, it is but reafonable, and even nereffary, to leave the Bees about half for their own ufe. In fome places, when the fammer is dry, and in coniequence there- of, the fields are lefs fruitful, then it is very difficult tor 'the Bees to gather a fufficient quantity of wax ; but in thole countries that are full of meadows, that are well watered, and produce a fucceffion of differ- ent flowers ; or even if there are woods, which by their lhade, preferve the moiftnefs and coolnefs of the air, and by that means caufe the ve- getation of a great number of plants, in the hotteft part of fummer, then the Bees will find every thing in plenty, neceffary for their ufe. It was forroely a cuftcm of the Egyptians, to carry the hives up the river Nile in boats, thai the Bees might enjoy the benefit of the flowers that grew upon the banks; thus they removed .them from place to place, that they might always enjoy the benefit of frefh flowers. The nations that live near the banks of the river Po, manage their Bees much in the fame manner, as the ancient Egyptians ; and the fame practice has been recommended in France ; but whether it has ever been done or not, is uncertain. Columella acquaints us, that the Greeks were accuftomed every year, to remove the hives from Achaia into Attica ; and the fame thing is done at this very day, in the dutchy of jfuliers, a diftrict of Wejlphalia, in Germany. One perfon in particular, in the territory, called Gatonis in France, has been at the pains of re- moving his hives, after the harveft of Sainfoin, into the plains of Btauce, where the melilot abounds, and then into Salogne, where it is well known the Bees may enjoy the advantage of Buck-wheat, till to- wards the end of September, tor fo long that plant retains its flowers. However this practice cannot be very agreeable to the Bees, becaufe their being carried in carts, difturbs them more, than if they were in boats upon the water. Authors have given different accounts of the length of the life of Bees ; but they have generally maintained, that they may live feveral years ; that is as long as a hive retains plenty of inhabitants ; but this is a bad reafon. Some affirm that Bees will live fix or feven years, and others upwards of twelve. Others again pretend to be certain, that a third part in every hive, dies in autumn, and as many in the fpring ; for which reafon they conclude, that they cannot live above a Angle year. It is pretty certain, that the Bees of each hive, are re- newed every year, or in two years time at moft. It is generally acknowledged, that the habitation of Bees ought to lie very clofe, and therefore it is their principal care, at firft when they ars Ufi NATURAL HISTORY. are hived, to flop up all the crannies. They make ufe of a fort of re-. finous gum, which is more tenaceous than wax, and differs greatly from it. This the French call propolis. It will grow considerably haid in June, though it will always grow foft with heat, and it varies in confidence, colour, and fmell. It has generally an aromatic, agree- able fmell, when it is warmed, infomuch that fome place it in the rank of perfumes. The outward colour is of a reddifh brown ; but the in- ward more yellowifb, and nearer the colour of wax. When the Bees begin to work with it, it is foft ; but it acquires a firmer confiftence every day; till at length it becomes harder than wax. The Bees carry it on their hinder legs, and fome think it is met with on poplar, birch, and willow trees ; but there are others that will fupply them with the fame. It is much harder for them to get it from hence, than the pow- der which is upon the Stamina of plants, and more difficult to manage, the Bees make ufe of the fame fubftance to cover the flicks laid crofs- ways, which help to fuppoit the combs; and often they plaifler a great part of the inner fides of their hives therewith. It is wonderful to confider how the Bees build their combs, whereia the cells are of fo regular a form, and applied fo ingenioufly, one againft another. Every thing feems to be difpofed with fo much fymmetry, and fo well finiihed, that at firft fight, one may be tempted to think, that they are the principal workmanfhip of thefe induftrious infects. All the cells are hexagons, that is, they have fix equal fides ; and this figure, not only takes up the leaft room, but is the moft capacious. It is no eafy matter to fee them at work, except by the affillance of a glafs hive. They are always ready to aflift each other, in laying the foundation of fome new comb, or enlarging the old, though a Specta- tor might conclude from the hurry that they are in, that there was no- thing but confufion among them. However it is eafy to perceive, that their teeth are the inftruments, by which they model and fafhion their combs. They begin at the bottom of their building, and'feveral of them work at a time, at the cells, which have two faces. But if they are Minted with regard to time, they give the new cells but half the depth which they ought to have, leaving them imperfect, and put off finifhing them, till they have Sketched out the number of cells, which are necefTary for the prefent time. The construction of their combs, cofts them a great deal of labour, for they are not able to make them in molds, as at firll fome might think they were. They are all bufied in erecting, Shaping, and polishing the cells that are unfinished ; and the ufe they make of them, is to lodge their honey, and to depofit their brood therein, for there the eggs increafe and grow, till they are transformed into Bees. But the cells defigned for the worms to change into drones, ought to be larger than the reft ; and for that reafon, they make fome with greater diameters than others. The cells of the brood, at different times, ferve for the honey-comb ; however thofe that were defigned for the honey only, are much deeper than the reft. When the harvelt of honey is fo plentiful, that they have no fuffkient room for it, they either lengthen their combs, or build more, which are much longer than the former. Sometimes they work at three combs at a time ; for when there are three workhoufes, more Bees may be employed at a time, without em- fcprraffing each other, and they can perform their bufinefs more readU NATURAL HISTORY. rrs Sy. The combs are generally parallel to each other, and they are Hightly faftened to the top of the hive. There is always a fpace be- tween two combs, which are like ftreets, that will only admit two at a time, a breaft. Though the combs confift of very thin leaves of wax, yet when they are full of honey, they become heavy. The Bees have a method of connecting their eombs to the fides of their hive, for which reafon, thofe that make them, fhould place fmall Micks acrofs each ©ther, to ferve as fupports to the combs that are to be built, this will fave the Bees a great deal of labour. The fubftance wherewith they make their combs, is gathered from flowers ; but not from every fort indifferently ; for it is only the ftamina. of flowers, that yield proper materials for making their wax ; for they find none ready made. It is very common to fee Bees fitting upoa flowers, with their bodies all over powder, which they could have got no where elfe. Sometimes they are fo full of it, that they become quite yellow, and might be miilaken, for another infect. However they take care to clean themfelves with the brufhes of their feet ; and to make the powder into two fmall balls, which they place in the two triangu- lar cavities of their hinder legs. Sometimes thefe balls are as large as a grain of pepper, a little flatted. When the flowers are not fully blown, the Bees pinch the tops of the ftamina with their teeth, where- in they know the grains of duft are enclofed ; and by this means they force them open. Some of thefe balls are yellow, others red, others of a whitifh yellow, and others again green. In April and May, the Bees are bufy from morning to evening, in gathering the wax ; but when the weather becomes hot, in June and July, they work only in the morning, till about ten o'clock, becaufe then the powder of the ftami- na, having been moiftened with the dew, or with the fluid that they tranfpire, is of a more proper confiftance, than at other times, to be moulded into a mafs. Tt is laid that the fecond ftomach is the organ, by which this powder is altered, digefted, and connected into real wax ; and is thrown out, through the fame paifage that it went in. It is with this fort of pafte, that they build their combs, and when it is dry, it becomes the fub- ftance, named Bees wax. Every comb newly made is white ; but they become yellowilh as they grow old, and the very oldeft ot all, become ilmoft black. But all thefe do not furnilh wax equally white, as is well known to thofe, whofe bufinefs it is to blanch it. However as it is neceflary for Bees to make a provifion of rough wax, there is in every hive, a pretty large portion of the combs, whofe cells are filled with nothing but wax ; and thefe are like fo many little magazines, where the Bees go to depofit their little balls, one after another, while other Bees take care to knead them, prefs them, and place them in order. The Bees fometimes come out of their hives a£ 4 o'clock in the morning, and continue labouring till 8 in the evening. They fly backwards and forwards, four or five times in a day, and fometimes more, for this depends on the length of their journies, and. the plenty of flowers. It is obfervable that the Bees extract but a fmall quantity of real wax out of the powder which they gather ; becaufe a great part of the ma- terials of wax, ferves to feed them ; it is alfo remarkable, that the drones never employ themfeiyes in making wax, all their nouriihmeiit being ii2 NATURAL HISTORY. being honey. With regard to the honey, it is but lately taken notice of, that there are veffels in flowers full of a fweet fluid, to which authors have given the name of nectarium, and it is to thefe that the Bees refort, to gather the liquor, which afterwards becomes hone) To this pur- poie, they make ufe of their tru ks, and with thele the Bees conduct the fluid to their mouths, caufng it to run along the upper part of their trunks. The powder of the ftamina, is not the onlv nounihment of Bees, for it is very well known, they do not make honey on purpofc for us. The fweet fluid falls from the oefophagus or gullet, into the firft ftomach, which while it U filled with hone), is in lhape like an ob- long bladder. Children that live in country places, are well acquaint- ed with this bladder ; and they even feek for it in the bodies of the Bees, and more efpecially in thofe of humble Bees, to fuck out the honey. When a Bee has fufficiently filled her firft ftomach it returns back to the hive, where it throws up the honey into a ceil. There is reafon to believe, that the honey does not return out of the body unchanged ; becaufe the firft ftomach is capable of contraction, in the fame manner as that of ruminating animals. It often happens, that the Bee, inltead of flying back to the hive, goes back to the places where the ether Bees are bufy in their feveral employments, and offers them honey, perhaps to hinder them from leaving off their work, to go in fearch of food. Some of the honey combs are always left open for common ufe, but many others are (lopped up, till there is a necefiity of opening them ; each of thefe are covered carefully with wax, fo clofe, that the covers feem to be made at the fame time. This practice tends to preferve the honey in the fame degree of fluidity, as they defign it lhould have. The ancients were of opinion, that the generation of Bees, was oc- cafioned by putrified fubftances, and not in a manner analogous to that of other animals. Some who have built their faith too much on what Virgil has faid in the fourth book of his Georgics, in the fable of the lliepherd Arijlaws ; and have taken a bull of two years old, have flop- ped up his notlrils, and afterwards killed him, and fo left him to putrify. But this procedure was fo far from producing fwarms of Bees, that they only met with thoufands of maggots, and a dreadful ftench. Others have publifhed variety of fictitious ftoiies, to acquaint the world in what manner thefe infects generated. During the greater part of the year, there is but one female in every hive, which may readily be diftinguifhed from other Bees, by the fhape of her body ; but it is fomewhat difficult to find her out. The males, Avho may be feen by hundreds, fpend almoft their whole lives in com- pany with the female. For this reafon, they are feldom out of the hive, but they lie idle therein, doing nothing at all, but feeding upon the honey, v/hich the working Bees have gathered. Neverthelefs they are not ufelefs, for though they do not work, they are abfolutely neceflary for the production of other Bees. f The Bee, called the Queen, is mod prodigioufly fertile, for fhe alone produces all the reft of the Bees in the fame hive. Infomuch that there is no connection that can be greater, than between the re if of the Bees and her. It is certain, that all the Bees leave off working, and take no farther care of futurity, after the death of the queen. She is full of a prodigious number of eggs ; and it is for the fake of thefe, that the Bees fee themfelves to work. Befides, if any other female Bee be NATURAL HISTORY. nj be put in among them, fhe is immediately acknowledged for queen. The life of all the reft, is nothing in comparifon of her's. They do her all manner of lervices, and pay her all the homage, that is due from, fubjecls to a fovereign ; for (he never goes abroad, without a numerous guard ; they keep her body clean with theif trunks, and follow her wherever fhe goes. When after her death the Bees continue in a ftate of perfect idlenefs j if another queen is prefented them, they immedi- ately apply to their labour again, tn fhort the life of the reft of the Bees depends upon that of the queen, for in a few days after her death, they will all fuller themfelves to die with hunger. The working Bees are always very provident in providing cells for the young ; and they will leave off their common employm< nt, to con- ftruifr proper receptacles for the eggs. They build purpofely, little cells, of a roundiih oblong fhape, and extremely folidj and they employ- great plenty of wax in this work. This polkiofi is greatly different from that of the other combs ; thefe fort of Bees, know, or at leaft ap- pear to know what number of eggs the queen lays in a year, from whence proceed other females, that give birth to feveral thousands of the working Bees, and feveral hundred males. Sometimes they do not lay but three or four at firft, and fometimes none at all ; but in this laft: cafe, the hives produce no fwarms. The fecundity of this Bee is fuchjj that in feven or eight weeks time, fhe will produce 10 or 12000 Bees and upwards; Generally fpeaking, (he lays but one egg in each cell; becaufe it would not be fufficient to hatch any more. In two or three days time, according to the heat of the weather, the egg will appear hatched at the bottom of the cell. It has the appearance of a kind of a maggot, which is always white, and placed in the fame attitude, that is, rolled up like a ring, lying foftly in a bed of a kind of gelly, of a whitifh colour ; and this is what the brood feeds upon. The common bees are a kind of nurfes to the brood, and have greater affection for it, than the hired nurfes among mankind. They take care in vifiting each Cell, and in examining whether any thing is wanting. They are fed with honey and wax, prepared in the bodies of the Bees ; and in lefs than fix days time, the worm comes to its full growth. When the Bees perceive that the worms have no farther occafion for feeding, they fhut them up in their lodgings, and wall them up, if the expreffion may be allowed, with wax. Then the worm continuing in a ftate of per- fect reft, begins to grow larger, and lines the walls of the cell with filken tapeftry, which they fpin in the fame manner as Caterpillars, be- fore they undergo their laft transformation. But it is obfervable, that the Bees bring them more nourilhment than they are able to confume. Before they fpin their covering, they eat up all their provision of gelly, leaving the bottom of the cell clean and dry. In a day's time, or long- er, they obtain their full growth, and then they caft off their fkins, which ferved them in their worm ftate, and become an Aurelia Nymph. The worms that produce Drones, are of the fame fize as thofe of the working Bees. Thefe laft take care of them with the fame application ; and it may well be imagined, that they are not lefs attentive to thofe which are to be metamorphofed into female Bees ; for it has been obferved, that they fupply them with nourifliment, in greater pro- fuMon* F When. jr4 NATURAL HISTORY. When all parts of the Aurelia have acquired the confidence proper' to the parts of the Bee ; then that which is to appear, opens its prifon,. by piercing with its teeth, the waxen cover about its middle. The Bee* which perceive that which is coming to light, flock about it, and feem to exprefs their joy, that they are going to be metamorphofed ; and this they difeover by their good offices. Two or three of them lick and clean all its fides with their trunks, and fome of them feed it with honey. Others again begin immediately to cleanfe the cell that has been juft left ; and carry away the filth out of the hive. As foon as the external parts of the young Bee bscome dry, it begins to difeo- ver what employment it is to have during life ; for it immediately pro- ceeds out of the hive, and goes in queft of flowers ; and is not at all at a lofs to find its way back to the common habitation. After this firft fally, it begins fometimes to gather the powder of the (lamina ; and Maraldi aifures us, that he has feen one of thefe, on the very day it came into the world, return back with two large balls of this fub- ftance. When the Bees firft begin to break their prifons, there is gene- rally above i oo of them in a day ; infomuch that in the fpace of a few weeks, the number of the inhabitants becomes fo great, that the hive cannot contain them ; and then they begin to falley out in fwarms. Young Bees are the browneft, with white hair ; and the old are of a lighter colour, with red hair. The fwarm is made on purpofe to feek out a new fettlement ; and that the head of it, is the queen ; for one of thefe is fufficient to condutt the whole fwarm. About five or fix days after the birth of a female Bee, fhe is ready to lay her eggs, and confequetttly is in a condition to place herfelf at the head of thofe that, are difpofed to follow her. In different countries, the fwarms make their fally at different times ;■ and in the fame country, they leave the hives fometimes fooner, and fometimes later. There ar,e feveral figns, which foretel when the Bees' are going to fwarm; but 'the moft certain is, when the working Bees do not fly into the fields, in their accuftomed numbers ; though the- weather feems to invite them. The time is from 10 in the morning, till 3 in the afternoon, that the fwarms leave the hives. When the fun ihines bright, efpecially upon the hive, it invites the Bees to feek their fortune ; for the heat has a great influence in this procedure, and renders the number more considerable. In lefs than a minute, all thofe that are to compofe the fwarm, leave the hive and flutter in the air, like flakes of fnow. However it does not appear that the queen chufes the place where they are to alight ; for feveral of the Bees, which are pleafed with a particular branch of a tree, go and fettle thereon ; and they are followed by many others, as well as the queen herfelf; but fhe does not join them, till there are a great number to- gether. When it comes to be pretty large, then it ioon is highly en- creafed ; infomuch that in about a quarter of an hour, they all feem to- be at eafe. Sometimes when they leave the hive, they rife fo high in the air, that they get out of fight ; and to make them come down, they throw handfuls of fand or duft after them. Some fuppofe that the Bees take the grains of fand for drops of rain ; but it is the com- mon method to beat brafs kettles and pans, as foon as ever they per- ceive the fwarm ready to fly. It is pretended, that the tinkling of thef*' NATURAL HISTORY. 115 thefe vefTels, is taken for thunder, and that it obliges the Bees to feek a proper place for a retreat. When the Bees are fixed, they caufe them to enter into a hive, rubbed with the leaves of balm, m.xed with a little honey. When thev make their firft folly, there may be feveral females, infomuch that a fwarm has fometimes two queens, and is even divided into two bands. But as it commonly happens, that one *t thefe is more confiderable than the other, the Bees who are fond of a large company, the fmalleft band dwindles by little and little, by their ROing to join the largeft. Thus a fwarm may have two queens, and fometimes more ; but they do not continue long, for the fupernu- meiary queens are always killed in the hive, where the fwarm fettles ; and till this cruel execution is performed, the Bees never fly abroad to work If there fhould be any female Bees left in the old hive, that did not go out with the fwarm, they always undergo the fame fate ; that is, thofe that have been newly transformed. Hence it follows, that there is never more than one queen in the lame hive. However it muft be obferved, that the Bees, never facrifice any of the females, when their hives are full of honey and wax ; and it is given as a reafon, that there is no danger at that time, to maintain a plurality of breeders. Bees in fome fenfe, obferve the fame rules as Wafps ; for when the time is come, that the males are no longer neceifary, the working Bees declare war againft them ; and in two or three days time, they make a dreadful havock amongft them ; infomuch, that the ground all round the hive, is ftrewed with dead bodies ; nay they will even kill thofe that are yet in their worm flate, or of that of an Aureha. This butchery is performed at different times ; for in fome hives, it happens in June, and in others not till July or Augujt. _ _ ' When the hive fends out feveral fwarms in a year ; that which hrlt proceeds therefrom, is always the beft, and moft numerous ; and then likewife they are able to lay up the greateft plenty of honey and wax It is remarkable, that a fwarm, always confifts of Bees of all ages and likewife there continues in the hive Bees of all ages. The number of them is always more confiderable, than that of the inhabitants of many larcre cities ; for fometimes they are upwards ot 40,000. It is wonderful to confider the activity of the Bees, when they firft enter an empty hive ; for often in lefs than twenty-four hours time, they will make combs, above twenty inches long, and feven or eight broad ; and fometimes they will half fill their hives with wax m five days; info- much that a fwarm will make more wax in the firft fifteen days, than they do afterwards all the reft of the year. When a fwarm is confider- able, and appears early, they fometimes fend out another the fame year. In confideration of the care and trouble that people are at, in taking care of the prefervation and multiplication of Bees, it appears reason- able that they ihould partake with them, of the fruit of their labour. But it is a kind of a barbarity to dellroy all the Bees with fulphur, or otherwife to get all the wax or honey ; and yet we fee this is often done, by thofe who make a trade of dealing in iuch commodities.^ In fome countries, this practice is forbid, and particularly in Tujcany. With proper care, a great number of hives might be faved every year, and there cannot be too many in thofe places that greatly abound in flowers. It muft be acknowledged, that honey is not in fuch great requeft as formerly, before the making of fugar was found out. How- ^ ' P 2 ever > n6 NATURAL HISTORY. ever it Is of great ufe ftill in many refpetfs ; and the confumption of wax is greater than ever. In France, a good fwarm in two years, will yield two pounds and a half of wax, and near thirty pounds of honey ; and therefore under a good regulation, a confiderable profit may be made of them. But Bees are Mill more beneficial, in countries that are covered with flowers the greateft part of the year, efpecially in hot countries, fuch as Spain, Peru, and Mexico, where tallow is always too (oft to make candles with. In Mufcovy, and in America, there is fometimes found in the trunks of old trees, a fort of black wax, in round bits, of the fize of a nut- meg. This is produced by fmall Bees, who make their combs in thefe hollow trunks, whofe honey is of a citron colour, and of a very agree- able tafle. This wax, when heated, has a fmell like balm, hut it is feldom to be met with in France. The Americans make candles with the wax, and likewife fmall vellels, which they make ufe of to gather the balfam oi Tolu. With regard to the medicinal qualities of Bees, it is well known, that they are diuretic, when reduced to powder, and the dofe is half a dram in a morning, incorporated with the extract of juniper berries; or it may be given in a glafs of diuretic wine. The fame powder ftrowed upon the head, will make the hair grow, and it will become thicker ;han before. There are two forts of honey, that is, the white and the yellow. The white is taken without fire from the honey-combs. Thefe they break foon after they are made, and lay them upon hurdles or mats of ofier, or on linen cloth, faftened at the four corners to as many pofts, and then an excellent white honey will fall from the combs, and grow hard in a fhort time. Afterwards they put it into glazed earthen pots, this they call virgin honey. Some preis this honey out, but then it is not fo agreable, for it will tafte of the wax. The beft fort of this honey, that the French are acquainted with, is that of Languedoc ; and they call it honey of Narbonne. It fhould be new, thick, granulated, of a clear tranfparent white colour, of a foft, and fomewhat aromatic fmell, and of a fweet and lively tafte. If it is very pure, it is almoft as hard as fugar candy; and that which renders it different from all others, are the many aromatic flowers, that grow in thofe parts ; and from which the Bees gather their honey. It is always obfervable, that the honey made in mountainous countries, where the fun has a great power, is more fine, and more fpirituous, than that which is produced in low grounds, not well warmed by the fun. Yellow honey is made from all forts of honey-combs, that is, old as well as new; and even of thofe from whence the virgin honey has been extracted. They break the combs, and heat them with a little water in bafons, or pots, keeping them continually ftirring ; then they put them into bags of thin linen-cloth, and thefe they put in a prefs, to fqueeze out the honey. The wax ftays behind in the bags, though there is always a little of it paffes through with the honey ; for when it is diftilled, there is always found fmall bits of wax that rife with the fpirit. Yellow wax fhould always be of a good confidence, of a fine yellow, and well tafied ; the French take that to be the beft, that is made in Camphagne, becaufe the foil is dry in that country, and the flowers aromatic. It contains a great deal of ellential or acid fait, and phlegm* NATURAL HISTORY. 117 phlegm, and a little oil and earth. The white honey contains the fame principles, but not quite fo much fait. The ancients, as has been already taken notice of, made greater ufe of honey, than we do at prefent, becaufe fugar was not then fo common ; but in fome cafes, it is dill preferred ; for it is more purging in glyders, and cleanfes wounds better, upon which account it is mix- ed with digedives. It is a greater prefervative of the compofitions into which it enters, than fugar, on account of its clamniinefs ; and for this reafon, it is made ufe of in Venice treacle, and mithridate. It alfo deferves to be preferred, btcaufe it contains the moft tffential fubftance of flowers, and may be faid to contain the quinteffence of aiomatic plants. Honey taken in fubdance, is pectoral, laxative, and deterfive, and is good in many difordes of the lungs, occafioned by a grofs phlegm. It alio loofens the belly, and is made ufe of in cly Iters. The whiteft honey is bed for inward ufe, as the yellow is for outward. Some ufe it as an aliment, and then it is eafy of digedion, and fupplies the blood with a new ballam of life ; however it is not good for dry bilious conditutions. We are told in the German ephemerides, that a. young country girl, having eaten a great deal of honey, became fo ine- briated with it, that flie flept a whole day, and talked a little idly the day following. The moll common preparations of honey for drink are mead, and jnethegelin; thefe in fnme countries are in high efteem. The common hydromel is made with boiling an ounce and a half of honey, with a quart of fpiing water, taking off the fcum ; after which it is drained through a cloth, and may be ufed as common drink. This is good againil coughs in old people, and when any perfon cannot bring up phlegm without difficulty. Some direct it againd internal ulcers, be- caufe they fuppofe it is an enemy to putrefaction. Vinous hydromel is made by mixing four pounds of virgin honey, with ten quarts of fpring water, and boiling it till about a third is con- fumed, or till an egg will fwim thereon. Then it is to be poured into a cafk, which mult be expofed to the heat of the fun, or in a dove for forty days; or till the liquor will ferment no longer, lhaking it from time to time. Then the cafk muff, be flopped up, and put in a cellar, to be kept for ufe. This ftrengthens the ftomach, and is very well tafted. There is kept in the fhops, other preparations of honey, namely, fimple oxymel, and oxymel of fquills. The firfl is made by mixing two parts of good honey, with one of white wine vinegar, and boiling it to the confidence of a fyrup. The dofe is half a fpoonful, and it is thought to be good to incide thick vifcous humours, that adhere to the bronchia of the lungs, in a moid adhma. Oxymel of fquills has the fame virtues, but much dronger. Honey-water, made by the chymifts, has an agreeable fmell, and a fliarpifh talk ; and it is looked upon as cordial, pectoral, and aperitive. Some waih their heads with it, to make their hair grow, or apply it every day with a fpunge. Spirit of honey is opening, and the oil is good againd rotten bones. Externally, wine mixed with honey, is very good to cleanfe ulcers, and affid in forming a cicatrice. Honey-water is good to clear the fight ; and take off the fpots of the cornea. Some make ufe of the mare of Beesj which is nothing elfe than what remains after the wae of n8 NATURAL HISTORY. of the combs is preffed out, to cure the pleurify. For this purpofe, they mix it with vinegar, and lay it between two clean linen cloths ; af- ter which they apply it as a poultice, to the pained part, and fprinkle it with vinegar from time to time, without taking it off. It is alfo good in cold and oedematous fwellings, which are hard to be refolved. Far- riers alfo make ufe of it, againft bruifes in horfes. Bees wax is compofed of two parts, namely, a great deal of phlegm, which keeps an acid diffolved, and an oil, It mould be new, hard, compact, a little glutinous to the touch, of a fine yellow colour, and of a pleafant fmell, fomewhat like that of honey ; but it fhould have no tafte at all. Virgin was, is that which is made without the help of fire; and is nothing but a preparation of the yellow; which muft be melted, waftied feveral times in water, divided into pieces, and layed upon linen cloths, which muft be expofed for fix weeks or two months to the fun, till it becomes white. Some make ufe of tartar, and chryf- tals of tartar, by which means they render it of a very fine white. When it is very white, clear, tranfparent, hard, brittle, taftelefs, and will not (tick to the teeth when chewed, it is beft ; for it is then emol- lient, and opening, as well as the yellow; but it is not fo refolutive, be- caufe the greateft part of falts are wafhed away. Bees wax ' in fub- flance, is feldom or never given inwardly ; though it has been ufed to cuie bloody fluxes; but it is prepared, by putting it into a hollow fweet apple, and which muft be roafted under hot cinders, in fuch a manner, that the wax muft melt, and enter into the fubftance of the apple. There muft be about two drams of wax, and the whole muft be given, thus roafted, in the aforefaid diforder; and the pain will vanifli immediately. The butter of wax, gained by diftiilation, is good to refolve cold tu- mours, and for pains in the joints ; as alfo for the palfy, as well as for parts that are frozen, and for chaps in the bread, when ufed as a lini- ment, and applied to the part affected. Four drops of the oil of wax, which is nothing but the butter rectified, given in a proper water, is very diuretic, and is good in the nephritic cholic. Some give ten drops for this purpofe. The propolis taken notice of above, is an attenuant and refolvent, and good to ripen boils, as well as for malignant ulcers. It is mixed in France, in platters and in ointments, and if the vapour of it is re- ceived into the mouth, by means of a funnel, it is faid to be very good to mitigate inveterate coughs. The method is, to throw bits into a cbafing-difh that has fire in it. There are feveral kinds of wax, and of different colours, which are occafioned by the ingredients that are added thereto. Thus green wax is compofed of white wax, foftened with a little turpentine, and colour- ed with verdigreafe in fine powder. This is good for corns in the feet, being applied thereto in the form of a plafter. Red wax is made in the fame manner, with the addition of vevmillion ; it is refolvent, when applied outwardly. The Bee File is a fort of fpecies by itfelf, it being of a nature between a Bee and a common Flie, and it feeds its brood with a fort of fweet pafte. The trunk differs from that of the common Bee, for its great- eft part is hid in a fort of fhelly fheath ; and when it is thruft out of it, it is accompanied with r. fort of threads, four in number; but when it is not ufed, it lies under the teeth. Under thefe there, is a fort of a flefhy NATURAL HISTORY. n? ferny feat, which is the real tongue of this Flie, with which it licks the trunk. The body is longer than that of any other Bee, and the rings that compofe the trunk neareft the bread-plate, are reddifh on the upper part. They make their nefts in the earth, nine or ten in- ches deep ; and fome of thefe Flies are armed with a fting, which are the females ; but the males, which are larger, have none. The Tapejiry Bees are fo called, from lining their nefts with a fort of tapeftry, which they get from the flowers of the wild poppy, newly blown, placing bits thereof at very fmall diftances from each other. The places where they chufe to build their nefts in the earth, are by the fides of highways, and the paths in corn fields. It is more hairy than the common Bee, but much of the fame colour, only fhorter in proportion ; when their neft is finifhed, they fill it with pafte like fome •f the former. There are feveral forts of foreign Bees, particularly thofe of Gauda- hupey which are lefc by one half than the European, and they are more black and round. They have no fting, and they make their hives in hollow trees, where if the hole that they meet with, is too large, they make themielves a fort of a waxen houfe, in the fhape of a pear, and in which they lodge, place their honey, and lay their eggs. Their wax is black, or at leaft of a deep violet-colour. They lay up their honey in waxen veflels, of the fize of a pigeon's egg, and in the fhape of the air-bladders of carps ; and they are fo joined together, that there is no fpace left between them. The honey is always fluid, of the confidence of oil, olive, and of the colour of amber. The wax is always too foft for candles, and therefore they make ufe of it inftead of corks, to ftop up their bottles ; and it is very good to foften corns on the feet, and warts ©n the hands, and when it has been applied for fome time, the corns may be drawn out. In 'Ethiopia there are little black Bees that make excellent honey, and they have no fting. In the Canary //lands, there are fwarms of Bees ©n the mountains, which produce large quantities of honey, but they are of different kinds. The Bees of Guiney make excellent wax, and delicious honey. In Congo and Angola there are two forts of Bees, one of which make their neft in the middle of woods, and the other on the roofs of houfes. Authors and travellers take notice of feveral forts of Bees, but as they are not particularly defcribed, nothing more needs lo be faid about them. CHAP. IX. OF INSECTS OF THE ANT KINI>. THE Ant is an infect, that keeps together in companies like the Bees, and maintain a fort of a republic, governed by laws. The neft is not exadtly fquare, but longer one way than the other, and in it there are a fort of paths, which lead to different magazines. Some of the Ants are employed in making the ground firm, by muing it with a ita NATURAL HISTORY; a fort of glue, for fear it fhould crumble, and fall down upon their heads. They may be ibmetimes feen to gather feveral twigs, which ferve them for rafters, which they place over the paths, to fupport the covering ; they lay others acrofs them, and upon them rufhes, weeds, and dried grafs, which they heap up into a double declivity, which ferves to turn off the water from their magazines. Some of thefe ferve to lay up their provisions in, and in others they lay their eggs. As for the provifions, they lay up every thing that is fit for them to eat ; and you may often fee one loaded with pippin, or grain of fruit, another with a dead Flie, and feveral together with the carcafe of a May-bug, or other infect. If they meet with any they cannot bring away, they eat it upon the fpot, or at leaft fo much of it, as may re- duce it to a bulk fmall enough for them to carry. They do not rurt about where they pleafe, at all adventures ; for fome of them are fent abroad to make difcoveries ; and if they bring back news they have met with a pear, or a fugar-loaf, or a pot of fweetmeats, they will run from the bottom of the garden, as high as the third ftory of a houfe, to come at it. They all follow each other in the fame path, without wandering to the right or the left ; but in the fields they are more at their liberty, and are allowed to run about in fearch of game. There is a fort of green Flie, that does a great deal of mifchief among the flowers, and which curl up the leaves of peach and pear-trees ; and thefe are furrounded with a fort of glue, or honey, which the Ants hunt after very greedily ; for they touch neither the plant nor the Flies themfelves ; however this is fometimes thought to be done by the Ants„ which raifes them a great many enemies, who endeavour to deftroy them, though they are really innocent of the fact. Next to this, their greateft paffion is to lay up hoards of wheat, and other corn, and for fear the corn mould fprout by the moifture of the fubterraneous cells, they gnaw off the end which would produce the blade. The Ants are often feen puftiing grains of wheat, or barley^ much larger than themfelves. The Ants after having fpent the fummer in labour, keep clofe in the winter, enjoying the provifions that they have laid up. However fome think they fleep in the winter, like other infe&s, and they do not lay in the corn for winter provifions, but to provide a (lore that is necef- fary to feed their brood with. They feed them as foon as they pro- ceed from the eggs, with inceffant care, which employs the whole com- pany. The young ones, when they proceed from the egg, are no lar- ger than grains of fand. After they have been fed for fome time, they weave themfelves a covering of white or yellow ftuff, and then they leave off eating, and become Chryfalides ; many people, while they are in this ftate, take them for Ant's eggs. But they are in reality the nymphs from whence the young Ants proceed. In Africa., and particularly in Guiney, the Ants are exceeding trou- blefome, and do a great deal of mifchief. They make their nefts twice as high as a man, of earth in the fields ; befides which they build large nefts in high trees, from which places they advance to the European fettlements, in fuch prodigious fwarms, that they frequently oblige the inhabitants to quit their beds in the night time. They will fometimes attack a living fheep, which in a night's time, they will reduce to a perfect fkeleton, leaving not the leaft thing except the bones. It is commos NATURAL HISTORY. izi common for them to ferve domeftic fowls in the fame manner, and even the rats themfelves cannot efcape them. If you place a Worm Or a Beetle, only where one or two Ants are, they will immediately depart, and bring with them above an hundred ; after which they feize their prey, and march off with it in good order. Thefe Ants are of various forts, fome gieat, others fmall, fome black, and others red ; " the (ling of this Tad is very painful, and cau'fes an inflammation ; 'lie white are as tranfparent as chrydal, and have fuch ilrong teeth, that in a night's time, they will eat their way through a thick wooden cheft, and make it as full of holes, as if it had been penetrated by hail ihot. There are alio feveral forts of Ants in the E ajl- Indies, whofe numbers are prodigious ; fome of them are exceeding large, and of a ruddy co- lour, inclining to black, and fome have wings, but others have none. They are very pernicious to the fruits of the earth, and do a great deal of mifchief in houfes, unlefs great care is taken to prevent them. It is remarkable, that if one Ant meets another that is loaden, it al- ways gives way to let it pafs freely. i. The Horfe-ant is the largeft of this kind in England, being twice as big as- the common fort ; it has a black head, and has a bread of a dufky iron-grey colour, only it is black towards the hinder part, and white at the other extremity. The legs are iron-grey, and the fcale which is placed between the body and the bread is of a roundifh oval figure, pointed at the top, and undivided ; the body is brown, and confifts of five fegments. It is ufually met with in hollow trees. 2. The red Ant is fmaller than the common fort, having a fmall head, and a large bread: ; and the fcale which feparates that from the body, is of a roundifh fhape, and {lightly dentated. The legs are {len- der, and the wings are very thin, and of a brownifh colour. It is met with in dry paftures, on the leaves and ftalks of the fmaller weeds. 3. The black Ant is neither fa large as the common fort, nor fo fmall as the red Ant, its head is large, in proportion to the body, and the breaft is flatted, being at fome diftance from the hinder part. The fcale that feparates them, is of an oval fhape, and undivided on the edges ; the legs are longer and {Tenderer than in the other kinds. It is met with in heaths, and in dry paltures.- 4. The common Ant is of a dark brown or reddifh colour, witli long legs, on the hindermod of which it will raife itfelf, as if it want- ed to fee at a didance. It has a large head, at the upper end of Which there are two prominent eyes, like thofe of a Fiie, but fmaller. On the fhout there are two horns or feelers, and beyond them two in- dented jaws,- which open fide ways, very wide, and at the ends of them there are teeth, which Hide on the fide of each other, when the mouth' is ihut. With thefe it is able to hold a body three times its own weight. It ha^ fix- legs, fiiaped like thofe of a Flie, and the body confifts of three joints or fegments, and fome of them have long wings, with which they are enabled to fly where they pleafe. The whole body is cafed with a fort of armour, and when viewed through a mfcrofcope, feenx covered with multitudes of fmall white fhining bridles, and the legs, feelers, head, and the middle part of the body, are furniihed with hairs, that are fmaller, and of a darker colour. Some have obferved, that as in Bees, thofe that make up the great body of the Ants,- a?e neither male nor female, thefe lad only having wings, and the refl none. The= m NATURAL HISTOKT. females are the hrgeft, the males of a middle fize, and the working Ants much lefs than either. 5. The American Ant is of a very large kind, and fo voracious, that they will devour all ihe leaves of a tree in a night's time. They have two crooked teeth, which meet each other like nippers, with which the> cut the leaves of trees, and other things that they feed upon. They fometimes cut them off, and when they are fallen to the ground^ they carry them to their nefls to feed their brood. Thefe Ants, when they are arrived to their full growth, fhed their coats in the fame man- ner as Flies that proceed from Caterpillars, and then become winged infects, in which Hate they lay their eggs. They make their holes in the earth of a great depth, and build their nefts very artificially. They are great en^iies to all other infects, and when they rove abroad, which is always once a year, they will go into every room of a houfe, and kill all the Spiders, and other infects that are therein. The American Velvet A?it is of the fiz-e of a Hornet, and the body is elegaiitly marked with black and crimfon velvet : the breaft is fo ftrong and hard, that though they are trod upon by men or cattle, they re- ceive no harm : they have a long iling in their tails, which occafions great pain and inflammation. The Ants of Brazil in South- America, are very numerous, and de- vour every thing chat comes in their way, whether fruit, flelh, fifh, or infects. There is alfo a flying Ant, an inch in length, with a triangu- lar head, and the body feparated into two parts, being only joined to- gether by a fmall tiring. On the head there are two llender and long horns, or feelers, and their eyes are very fmall. On the fore part or breaft, there are fix legs, confiding of three joints, and they have four thin tranlparent wings, the hindermoft of which are round, and are of a bright brown colour. They dig into the ground like moles ; but they are eaten by the negroes. There is another large Ant, refembling a Flie, whofe body is fepa- rated into three diiHnct parts, the hindermoft of which for fhape and iize, refembles a barleycorn; the middlemoft is of an oblong fhape^ with fix legs, each of which is near half an inch long, and confift of four joints : the fore part, or head, is pretty thick, and in the fhape of a heart, wLh two horns or feelers, and as many black crooked teeth : the eyes round the pupils, are inclining to black, and the fore and' hind parts of the head are of a bright red colour. There is alfo a bright black Ant with bright rough legs, near an inch in length with a large four-fquare head, and prominent black eyes and teeth, with two horns or feelers, near half an inch long: the body of this is alfo feparated into three parts, the foremoft of which is of an oblong ihape, but not very thick, with fix legs, each of which is near half an inch long : the middle part is fmall and fquare, not exceeding the bignefs of a luufe : that behind is the largeft of the three, and is of an oval figure, only it is iharp at the end : the three parts are faftened together by a fort of tiring. The chefnut brown Ant is alfo a native of Brazil, and has a head as 1 r than that behind. At certain feafons of the year it has four wings,, the- NATURAL HISTORY. ie3 the foremoft of which are fomewhat larger than the hindermoft, but it lofes them again after a certain time. Linnaus takes notice of four forts of jfnts, namely, the horfe Ant, the red Ant, the black Ant, and the corn Ant. CHAP. X. of the ant. (From Goldsmith.) THOUGH the number of two- winged flies be very great, and the naturalifts have taken fome pains to defcribe their characters and varieties ; yet there is fuch a fimilitude in their forms and manners, that in a work like this, one deicription mull: ferve for all. We now therefore, come to a fpecies of four-winged infects, that are famous from all antiquity, for their focial and induftrious habits, that are mark- ed for their fpirit of fubordination, that are offered as a patron of par- iimony to the profufe, and of unremitting diligence to the fluggard. In the experiments, however, which have been more recently made, and the obfervations which have been taken, much of their boalled frugality and precaution feem denied them ; the treafures they lay up, are no longer fuppofed intended for future provifion, and the chsice they make in their ftores, feems no way dictated by wifdom. It is, in- deed, fomewhat furprifing, that almoft every writer of antiquity fhould defcribe this infect, as labouring in the fummer, and fealting upon the produce during the winter. Perhaps, in fome of the warmer climates, where the winter is mild, and of fhort continuance, this may take place ; but in France and England, thefe animals can have no man- ner of occafion for a fupply of winter provitions, as they are actually in a (fate of torpidity during that feafon. The common ants of Europe, are of two or three different kinds ; fome red, fome black, fome with flings, and others without. Such as have flings inflict their wounds in that manner; fuch as are unprovided with thefe weapons of defence, have a power of fpurting, from their hinder parts, an acid pungent liquor, which, it ii lights upon the ikin, inflames and burns it like nettles. The body of an ant is divided, into the head, bread, and belly. In the head the eyes are placed, which are entirely black, and under the eyes, there are two fmall horns or feelers, compofed of twelve joints, all covered with a fine filky hair. The mouth is furnifhed with two crooked jaws, which project outwards, in each of which are feen inci- fures,"that look like teeth. The breaff is covered with a fine filky hair, from which project fix legs, that are pretty flrong and hairy, the ex- tremities of each armed with two fmall claws, which the anisnal ufes in climbing. The belly is more red than the reft of the body, which is of a brown chefnut colour, lhining ai glafs, and covered with ex- tremely fine hair. 0^2 From I?4 NATURAL HISTORY. From fuch a formation, this animal feems bolder, and more aduve, for its fize, than an> other of the infect tribe;, and fears not to attack a creature, otten above ten times its own magnitude. As foon as the winter is pad, in the firft rine day in April, the ant- hill, that before feemed a defert, now fwarms with new life, and niy- liads of thefe infers are feen juft awaked from their annual lethargy, and preparing for the pleafures and fatigues of the feafon. For the firft day they never offer to leave the hill, which may be coniidered as their citadel, but run over every part of it, as if to examine its preient fituation, to obferve what injuries it has fuftained during the i igours of ■winter*, while they flept, and to mediate and fettle the labours of the day enfuing. At the firft difplay of their forces, none but the winglefs tribe ap- pears, while thofe furniihed with wings remain at the bottom. Thefe are the working ants, that fir It appear, and that are always deftitute of wings ; the males and females, that are furniihed with four large wings each, are more flow in making their appearance. Thus, like bees, they are divided into males, females, and the neu- tral or the working tribe. Thefe are all eafily diftinguifhed from each other ; the females are much larger than the males ; the working ants are the fmalleft of all. The two former have wings ; which, however, they fometimes are divefted of; the latter never have any, and upon them are devolved all the labours that tend to the welfare of the com- munity. The female, alfo may be diftinguiihed, hy the colour and ftrutfure of her breaft, which is a little more brown than that of the common ant, and a little bigger than that of the male. In eight or ten days after their firft appearance, the labours of the hill are in fome forwardnefs ; the males and females are feen mixed with the working multitude, and puri'ued or purfuing each ocher. They feem no way to partake in the common drudgeries of the ftate ; the males purfue the females with great affiduity and in a manner force them to compliance. They rem'ain coupled for fome time, while the males thus united, fuffer themfelves to be drawn along by the will of their partner. In the mean time, the working body of the ftate takes no part in their pleafures, they are feen diligently going from the ant-hill, irt purfuit of food for themfelves and aifociates, and of proper materials for giving a comfortable retreat to their young, or fafety to their ha- bitation. In the fields of England, ant-hills are formed with but lit- tle apparent regularity. In the more foutheren provinces of Europe, they are conftrucled with wonderful contrivance, and offer a fight highly worthy a naturalift's curiofity. Thefe are generally formed in the neighbourhood of fome large tree and a ftream of water. The one is coniidered by the animals, as the proper place for getting food ; the other for fupplying them with moifture, which they cannot well difpenfe with. The fhape of the ant-hill, is that of a fugar loaf, about three feet high, compofed of various fubftances ; leaves, bits of wood, fand, earth, bits of gum, and grains of corn. Thefe are all united into a compact body, perforated with galleries down to the bottom, and winding ways within the body of the ftruclure. From this retreat, to the water, as well as to the tree, in different directions, there are many paths worn by conftant affiduity, and along thefe the bufy infecls are feeu J Mcjijoires pour fervir a/1 Hifiorie des infeftes par Charles de Geer. NATURAL HISTORY. 12- ieen paffing and repafilng continually ; fo that from May, or the be- ginning ot June, according to the ftate of the fealon, they work con- tinually, till the bad weather comes on. The chief employment of the working ants, is in fuftaining not only the idlers at home, but alfo finding a fufficiency of food ior themfelves. They live upon various proviiions, as well of the vegetable as of the animal kind. Small infects they will kill and devour ; fweets of all kinds they are particularly fond of. They feldom, however, think of their community, till they themfelves are firft lariated. Having found a juicy fiuit, they fwallow what they can, and then tearing it in pieces, carry home their load. If they meet with an infect above their match, feveral of them will fall upon it at once, and having mangled it, each will carry off a part of the fpoil. If they meet, in their excurfions, any thing that is too heavy for one to bear, and yet, which they are unable to divide, feveral of them will endeavour to force it along ; ibme dragging and others pufhing. If any one of them happens to make a lucky clifcovery, it will immediately give advice to others, and then at once, the whole republic will put themfelves in motion. If ia thefe (truggles, one of them happens to be killed, fome kind furvivor will carry him off to a great diftance, to prevent the obllructions his body might give to the general fpirit of induliry. But while they are thus employed in fupporting the ftate, in feeding abroad, and carrying in provifions to thofe that continue at home, they are not unmindful of pofterity. After a few days of fine weather, the female ants begin to lay their eggs, and thofe are as affiduoufly watch- ed and protected by the working ants, who take upon themfelves to fupply whatever is wanting to the nafcent animal's convenience or ne- ceffity. They are carried as foon as laid, to the fafeft iituation, at the bottom of their hill, where they are carefully defended from cold and moitture. We are not to fuppofe, that thofe white fuottances which we fo plentifully find in every ant-hill, are the eggs as newly laid. On the contiary, the ant's egg is fo very fmall, that, though laid upon a black ground, it can fcarcely be difcerned. The little white bodies we fee, are the young animals in their maggot ftate, endued with life long fince freed from the egg, and often involved in a cone, which it has fpun round itfelf, like the iilk worm, 'lhe real egg when laid, if viewed through a microfcope, appears fmooth, polifhed, and fhining, while the maggot is leen compofed of twelve rings, and is often larger than the ant itfelf. It is impofhble to exprefs the fond attachment which the working ants fhew to their riling progeny. In cold weather they take them in their mouths, but without offering them the fmalleft injury, to the very depths of their habitation, where they are lefs fubject to the feverity of the feafon. In a fine day they remove them, with the fame care, nearer the furface, where their maturity may be affilted by the warm beams of the fun. If a formidable enemy lhould come to batter down their whole habitation, and cruih them by thoufands in the ruin, yet thefe wonderful infects, ftill mindful of their parental duties, make it their fir ft care to fave their offspring. They are leen running wildly about, and different ways, each loaded with a young one, orten bigger than the infect that fuppcrts it. 1 have kept, fays thvammerdam, leveral of $he workine ants in my clofet, with their young, in a glafs filled with earth u6 NATURAL HISTORY. dearth.
