TO THE FIRST EDITION.
VOL. II.
To gratify a laudable curiosity, and lead the mind to the exercise of one of its noblest faculties, was the motive that first encouraged me to publish a work of this kind. How far it has answered these ends, what pleasure it has produced, of what benefit or advantage it has been to mankind, by inducing them to contemplate the admirable works of Providence, and trace its wisdom and goodness through the medium of this branch of the history of nature, are circumstances, the confined sphere of life in which I have hitherto moved, has not given me those opportunities of knowing that I could wish. But the kind reception the first volume of this work has met with, seems to justify the opinion that it has not been written in vain.
In the Preface to my former volume, I told my readers, that my design of giving an addition to that work, would entirely depend on the reception the public should be pleased to give it. I was willing to have some proof of the public approbation, before I ventured rashly to engage further in so considerable an expense as the engraving and colouring the plates, &c. which was too great for me to incur without a prospect of a reimbursement.
It is now with the utmost pleasure I can declare, that I have the greatest reason to be satisfied on that head; the world has generously encouraged my first attempt, and it is to that cause the present volume owes its appearance. The quick sale of a great number of copies, on the first publication, was a proof of the great progress natural history had made; and gave me the utmost hopes a continuation might be equally as acceptable, if conducted on the same plan, and rendered as agreeable by the exertion of the artist's abilities. I have now the satisfaction of offering a volume to the public not inferior to the first.
It is a pleasing reflection to consider the great strides natural history is making in this kingdom, as well as in other parts of the world; and the many publications on the various subjects of nature, that have made their appearance within these last three or four years, is a circumstance that must give every man of a liberal mind the greatest satisfaction. We see persons, skilled in natural history, receiving encouragements and reward from men of rank and property, according to their respective abilities. Some are encouraged to pursue their studies in foreign parts, and investigate the secrets of nature among the trees and plants; others are employed in discovering countries, and searching the shores of coasts, hitherto unknown, for subjects that will afford either profit or speculative pleasure; while the artist at home is not neglected and abandoned, but meets the reward his merit entitles him to.
Natural history has, certainly, less reason to court the favour of mankind than many other branches of knowlege; as the pursuit of it, either as a science or amusement, is so replete with pleasure, that it is hardly possible to refuse it our approbation and encouragement, so soon as we give ourselves the least time to enquire into its merits; and we are often stimulated to pursue it from the appearance of that inexhaustible store of entertainment it is sure to afford. It is therefore less to be wondered at that publications on these subjects are more numerous than formerly; as the desire of communicating knowledge and happiness is irresistible, and men, for their own sakes, will be induced to follow the tracks, where the enjoyment of unallayed pleasure lies within their grasp.
I shall not dwell any longer on this part of the subject, but inform the reader, that the same plan, of giving just and accurate figures, that was followed in the first volume, is continued in this. The utmost care and nicety has been observed, both in the outlines and engraving. Nothing is strained or carried beyond the bounds nature has set; and whoever will compare the engravings with the originals, I flatter myself will allow, that nothing is borrowed from fancy, or any colour given to an insect that does not really exist in the subject intended to be represented.
It is true, the want of those remarks and observations on their natural history, similar to those inserted in my first volume, is a circumstance I have great reason to lament. I mentioned my opinion of the cause in my former address, in which I have since been confirmed by repeated proofs; and notwithstanding the great labour and trouble I have been at, not only in procuring the subjects of the present volume, but in endeavouring also to get the natural history of some of the most extraordinary of them, I have not been able to obtain one single piece of information proper to be laid before the public.
It is to little or no purpose to make further enquiry into the reasons of this want of curiosity, among all ranks of people, situated in distant climates, more than I have already done. I find it is so; and whether it proceeds from an ill-judged pride, in thinking such minute animals below their notice, or whether it arises from that languor of mind, as well as of body, that generally prevails in warm climates, is a matter of no consequence to mankind: the world is not benefited by their situations, and we must be content to remain in our present ignorance, till Providence shall think proper to give us a second Swammerdam, or Reaumur, &c. and place him in a distant part of the globe, for the advantage of the human race.
It is necessary to mention, that both the descriptions, and engravings, were finished about the beginning of the year 1771, and as some of the insects are mentioned as non-descripts, that since that time have appeared in other works, I hope I shall not be considered as guilty of an imposition on that account.
The present age has made great improvements in entomology, as well as other parts of natural history. The many publications that have appeared on that subject within these two years, are proofs how well works of this kind are received; and as all iconographers aim at giving representations of unfigured subjects, it is no wonder if some contained in this volume should be presented to the world by those who happened to have got the start of me. The plates were actually engraved, and great part of the prints coloured, before I discovered that any of the subjects had been figured by other authors; and to have suppressed them on account of the very few that are found in other works, would have incurred an expense greater than the nature of the case would allow.
The objection made of the want of names to the insects contained in my first volume, the reader will here find removed; and trivial as well as generical ones, given to every insect in the whole work: and likewise a few errors of the press corrected, that have almost imperceptibly got in. I was, indeed, truly sensible of the defect and incompleteness of that volume, occasioned by the above circumstance, and would gladly have named every insect then delineated; but the different opinions subsisting at that time among entomologists, some preferring one author and some another, made me exceeding cautious of entering on that business: and I rather chose to defer it to the present opportunity, than give occasion for any reflections against me, for my attachment to an author, whose method I should certainly have pursued, and whose works have deservedly entitled him to the appellation of father of natural history. I mean the excellent Linneus, whose system seems now to be generally approved and followed; and I must here mention, the opportunity that the present work affords of giving an explanation of the terms, &c. in his work, I should certainly have availed myself of, for the benefit of the young beginner; but as my friend, Mr. Curtis, has published a good translation of the "Fundamenta Entomologiæ" of that author, wherein the young student, as well as the adept, who are not versed in the Latin tongue, may receive great improvement; I must refer them to that work for the properly understanding the plan and design of that great author.
The reader will observe, that in giving trivial names I have strictly followed the method of Linneus. The Butterflies entitled to be ranked among the Equites, are named after some great personage found among the Greeks and Trojans; as in Plate iii. Fig. 1. where I have named the insect Antenor, from a Trojan prince; and Plate ix. Fig. 1, 2. Menestheus from a Grecian one; one belonging to the Eq. Trojanes, the other to Eq. Achivi. I have likewise followed his rule in naming the insects belonging to other classes; and given such as I concluded to be the most easily retained in the memory. To this end also I have used the Latin language in preference to the English, for the great liberty it allows of compounding and decompounding words and names; a circumstance of the greatest consequence in a business of this sort.
I should think myself totally unpardonable, if I finished this address without acknowledging the obligation I am under to several friends, whose assistance in this work claim the utmost return of gratitude; among these, in a most particular manner I must mention Dr. Fothergill, whose readiness to encourage and promote every part of natural history, must endear him to every man who wishes well to so useful and beneficial a branch of knowledge; and it is to the kindness of that gentleman the reader will perceive I am indebted for a great number of figures that form a considerable part of this work; many of which are so very rare, as not to be met with in any other cabinet.

Habitat: Surinam (Drury). "In Indiis." (Linn.)
Upper Side. Head, thorax, and abdomen dusky brown. Anterior wings fine mellow dark brown or snuff colour towards the tips; but near the body, glowing with a fine dark glossy purple. Near the tip of each wing are two small white specks, one scarcely visible; on the lower part of each wing is a rather large oval spot, of the same snuff colour with that near the tips. Posterior edges circularly dilated, and gradually widening from the shoulders to the external edges. Posterior wings dark brown, but glowing all over in some directions with a dark glossy blueish purple. Near the abdominal corners are two black eyes on each wing, surrounded by beautiful dazzling blue.
Under Side. Breast and sides yellowish sandy-coloured. Anterior wings divided into three parts by two lines or bars; one being brown and narrow, the other white and rather broad. The first division, next the body, is of a russet or light hair colour, tinctured with pearl, having a short black streak near the middle; the next, or middle division, is light brown; the third is dark clay-coloured. A considerable number of long hairs arising from a single point or stalk, spreading like the leaves of a fan, and occupying the space corresponding with the oval spot mentioned before; those on the outside bending downwards, and curling. (See Fig. 3. This circumstance is peculiar to one sex only.) Posterior wings next the body russet, with a single black spot near the middle of each. Abdominal groove russet. Middle of the wing with a rather broad bar of a fine deep chocolate colour, beginning at the anterior edge and ending at the abdominal groove; the upper side of the bar next the body being russet. Lower part of the wing, next the external edge, of a colour between russet and chocolate, with three small white spots near the upper corner. The two black eyes are distinct on this side, with narrow blue irides. The wings are a little dentated.
Drury's figure represents an individual in which the posterior wings have no appearance of the short tail, which the species ordinarily exhibits. It may, perhaps, originate in the figure being taken from a mutilated specimen. The Papilio Morna of Fabricius, appears nearly allied to this insect.

Upper Side. Antennæ ringed with white and black. Anterior wings greyish brown, without markings. Posterior wings of the same greyish brown. Cilia white. A little above the abdominal corners are four white spots, placed close together; the two inner ones being smallest. Each of these wings is furnished with three tails, the upper parts of which are black, the other parts white; the middle one being almost as long as the wing, the other two are about half that length.
Under Side. Palpi, head, and breast white. Legs white and brown. Wings fine silvery white. A small, narrow, orange-coloured line begins at the middle of the anterior edge of the fore wings: which, crossing them and the hind ones, runs almost to the abdominal corner, where it suddenly turns back and ends at the abdominal groove. Near this part are two small black spots, one placed between the two outer tails, and the other on the abdominal edge.
Fabricius gives the sexes of this insect as distinct species, under the names cited above, stating India to be the habitat of Hesiodus (or the male). Palisot de Bauvois has, however, satisfactorily cleared up the error, by figuring both sexes from Africa. The male has the disc of the wings, on the upper side, of a rich blue colour.

Habitat: Central Africa.
Upper Side. Antennæ red brown, but thickening gradually to the tips. Head fine scarlet. Thorax velvety black. Abdomen white with scarlet rings. Anterior wings black, with three rows of cream-coloured spots on each; the two upper ones next the anterior edge being a little confused by running into each other; the lower one, running parallel with the external margin, is more regular. These spots, being nineteen in number, are of different sizes and shapes; some being round, some oval, triangular, &c. Posterior wings black, with two tails; having four rather broad scarlet crescents placed above each of them, the ends of which are verged with cream. On the middle of each wing is placed a great number of small powder-like spots of a golden green colour; and on the abdominal edges, just below the body, are two scarlet and cream crescents placed opposite each other. The upper part of each wing exhibits ten cream-coloured spots of different shapes and sizes, whereof three are larger than all the rest.
Under Side. Breast scarlet. Sides black. Abdomen scarlet, with white rings. Wings coloured nearly as on the other side; the spots being rather more distinct, the crescents broader, and the cream edges stronger than on the upper side. All the wings are dentated; the superior very faintly, the inferior very deeply.
Drury states that he was ignorant from what part of the world his specimen (which was given to him by Mr. Leman) came from. No other individual of this species is recorded to exist in the modern collections, and it is from the figure and description of Drury that all subsequent writers have derived their knowledge of this splendid and unique insect.
Donovan, however, figured this butterfly, or rather copied Drury's figure in his beautiful work upon the Insects of India, observing merely that it might be "mentioned with much propriety amongst the rarest of the Papilio tribe found in India," without giving any account of the source from whence his figure and information had been obtained.
At the sale of Mr. Drury's collection, this butterfly composed lot 4 of the first day's sale, May 23, 1805, and was purchased by Mr. Latham at the price of £2. 12s. 6d.
The Rev. F. W. Hope, however, possesses a specimen, which he has informed me, that he obtained in a small collection of rare insects from tropical Africa, collected by the late Mr. Ritchie.

Habitat: Sierra Leone (Drury). Coast of Guinea, Caffraria, Madagascar (Bdv.). India (Linn. & Fabr.).
Upper Side. Head, thorax, and abdomen velvety black. Wings fine deep black; with two narrow bars of a beautiful Saxon or blueish green colour, which begin about the middle of the anterior edges of the anterior wings, and crossing both them and the posterior, meet at the abdominal edges near the abdominal corners, running parallel with the external edges. Anterior wings with two small blue spots placed on each near the tips, and another, larger, divided into three by the nerves, near the middle of the anterior edge; being placed at the top and even with the bar, but divided from it by a small separation of black. The edges of these wings are entire. Posterior wings with six blue spots on each, placed along the external edges; the four lower ones being in pairs, and another small one at the abdominal corners; margins deeply angulated.
Under Side. Breast and sides dark brown, spotted with white. Abdomen brown. Wings dark brown hair-coloured, immaculate, except the posterior ones, which have a row of eleven cream-coloured spots running along the external edges.
The female differs from the male in being somewhat larger in size, with the spots on the upper side of a brighter green colour, and with the marginal row of spots on the under side of the posterior wings of a pearly greyish hue, and with a tinge of this colour upon the disk of the wings. Cramer has figured the male as the female, and vice versa. Mr. Smeathman informed Mr. Drury that this insect feeds upon the orange and lime trees, about which the butterfly is always seen flying, considering it as remarkable that most of the insects which feed upon the orange or citron tribes, have some tinge of green upon them; in like manner the beautiful green snake, so common about Sierra Leone, is always to be found about these kind of trees. These circumstances led our author into a series of observations which, though upwards of half a century old, may still be read not only with pleasure, but with the hope of beneficial results.
"The particular qualities, dispositions, and uses of by far the greater part of insects, as well as of plants, are at present totally unknown to us, nor are the methods by which we are to acquire that knowledge at present ascertained.
"Their colours have hitherto been of no further use to us than merely to discriminate one genus or species from another; and yet it is possible that, by a combination of observations even on the colours of insects, we may form some ideas of their natures and properties.
"The observation of Mr. Smeathman, if well founded, supposing it did not lead to a discovery of the nature and properties of an insect itself, might at least indicate those of the plant on which it feeds. The various species of the Danai Candidi, among which are included the different white butterflies of Europe, feed chiefly on such plants as are reckoned not only nourishing, but salutary to the human body, such as the various species of cabbages, coleworts, turnips, &c. Every foreign country produces butterflies of that family; some of them so very like those of Europe, that it is a fair inference they feed on plants of a similar property. This is countenanced by many corroborating circumstances. The Papilio Iris, and the various Fritillary butterflies fly exceedingly swift; and it appears from Mr. Smeathman's observations, that foreign butterflies that bear a resemblance to them, also fly exceedingly swift. The green and golden Scarabei of this country are found to delight in flowers; those of the hot climates are also found on flowers; while the black, purple, and darker coloured Scarabei, are generally found frequenting the excrements of animals, and are, in every quarter of the globe, called Tumble dung-beetles, from their making balls of those substances, and rolling them to their holes. The locust tribes feed here chiefly on grasses and roots; so it appears they do in the torrid zone. Those of the torrid zone are found to be wholesome food. The inference is plain, that those of this climate, in case of necessity, or perhaps even as an article of luxury, might be found the same.
"The caterpillars of certain beetles, from his account, are the greatest delicacies of the hot regions. They might, in some degree, be found to be so here. The palm-worm of the West Indies, which is sought at a monstrous expense, is the caterpillar or maggot of a beetle, of the same genus with that small beetle, which is produced from the maggot or caterpillar in a hazel-nut or filberd. This is often eaten here, and esteemed by those who do so as more delicate than the nut itself.
"The Cantharides is a green beetle. A green beetle of our own, Cerambyx Moschatus, is found capable of raising blisters; and other green beetles may probably have the same effect.
"The butterflies that are found in the cultivated spots of Africa, have in shape and appearance a strong resemblance to many of ours, particularly the white ones. These seldom visit the thick woods; but, when seen in any number, are certain indications of neighbouring plantations. This observation might save the lives of bewildered travellers: as in some instances it might be dangerous to enter into a very large wood, or a thick part of it; in others again, immediate safety might be the consequence of leaving a forest, by following the indications of an open or cultivated spot. The analogy between the colours, the dispositions, and the qualities of insects, may yet be greater, and between insects, and the plants on which they feed, still more useful; for if an insect is found in one part of the world to feed on a plant useful in food, medicine, or manufactures, an insect of a similar appearance, in another part of the world, will in all probability be found to feed on a plant of similar virtues. We do not know but insects may affect, when perfect, to frequent different soils; or to visit the recesses, where valuable drugs remain hid from human search, and useless to mankind.
"As, however, observation and experience have demonstrated, through length of time, that useful hints may be drawn from very trivial properties in the smallest insects, it seems that none are unworthy of being noted. Future travellers may draw useful inferences from those now given, and may add to the number, for the benefit of those who follow after them. There can be no doubt that every species of insect has its use in the creation, and probably there are few from which mankind might not derive some advantage, if their nature and properties were ascertained. We know of a few direct methods, and must therefore in general wait with patience, till a variety of observations, such as Mr. Smeathman has given us, by being frequently compared, strike out new lights upon this part of science, and elucidate matters at this time buried in obscurity. The uses of many insects in the creation are obvious at the first sight: such, for instance, are those which feed on putrid animal or vegetable substances; while others promote the general good by such remote means, that we cannot immediately see to what end their operations verge. We are not therefore, however, to suppose them mere expletives in the great system of beings; neither are we rashly to attribute an importance to them which they do not deserve, or ridiculously affect to admire circumstances in them of little moment, and praise the Creator for dispositions of a secondary nature.
"When I recommend observations to be made on the most trivial circumstances, it will readily be conceived I do not wish to derogate from experiment, from which alone solid hopes are to be formed, and those which have been hitherto made give great encouragement. Mr. Reaumur has found that the moth, which feeds on clothes, refines the colour with which they are dyed in a wonderful manner; for the excrement of the animal is the colour of the cloth on which it is fed; and therefore, for miniature paintings, infinitely surpasses all others. How far this kind of experiment can be refined on, must be left to the curiosity and diligence of travellers and experimental philosophers, who may perhaps, in some part of the world, realize and improve this reasoning upon a large and useful scale."
