{iii}MR. DRURY'S PREFACE

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 {iv}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.

{v}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 {vi}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. {2}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.

HABITAT: Sierra Leone (_Fabr._). Gold Coast (_Drury_).

_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 {5}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. 12_s._ 6_d._

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 {7}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, {8}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 {9}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."

transparent eye in the middle of each; those in the superior being
largest. These eyes are encircled with a narrow yellow edging, then with
a greyish band, and lastly with a narrow black line; the transparent
pupil appearing as if a fine hair crossed it. The anterior edges of the
superior wings have a grey margin from the shoulders almost to the tips,
where the reddish colour is paler than on the rest of the wing. A narrow
dark line begins near the tips, and runs along the external edges to the
lower corners, which is continued along the external edges of the
posterior wings to the abdominal corners. On these wings a faint arched
line of a dark colour is observable over each eye.

_Under Side._ Breast, feet, and abdomen grey. The wings greyish brown;
eyes appearing as on the upper side. A faint dark-coloured bar, beginning
at the anterior edges of the anterior wings, and running across the lower
parts of the eyes, is continued along the posterior ones; where it
crosses the middle of the eyes, and ends at the abdominal edges below the

HABITAT: Sierra Leone.

_Upper Side._ Antennæ black, setaceous. Tongue long and spiral. Head,
neck, thorax, and abdomen yellow. Anterior wings pale clay-coloured; but
next the shoulders yellow, gradually changing to a white towards the
middle of the wings, and occupying almost half of them; each wing having
six small black spots on the yellow part, three being placed on the
anterior edge, and the other three near the shoulder, where likewise is
another small spot. Posterior wings white, immaculate.

_Under Side._ Palpi long and yellow at the base, but the ends are black
and filiform. Legs white, striped with brown. Breast and abdomen white.
Anterior wings with the tips pale clay-coloured, as on the upper side;
all the remaining part being white. A small black bar begins about the
middle of {11}the anterior margin, and crossing the wing ends at the
lower corner. Next the shoulders is a small tuft of hairs of a silver
colour placed on each wing. Posterior wings white and immaculate. The
margin of the wings entire.

This and several nearly allied species of tropical moths constitute a very distinct subgenus characterized by the prevailing colour, the spots at the base of the wings, the elongated palpi, and the peculiar neuration of the anterior wings. I have not, however, ventured to propose the establishment of a subgenus for them. They appear in some respects to be allied to the genus Leucania.

HABITAT: Gold Coast of Africa.

_Upper Side._ Head light green. Eyes black. Antennæ thread-like, and very
long; appearing at the middle as if they had been broken, and had
branched out again to their proper length. Thorax and abdomen light
green. Tail dark brown. Wings fine light green, almost transparent, and
resembling mother of pearl. Anterior edges of the anterior wings pale
orange-coloured.

{12}_Under Side._ Palpi, neck, breast, abdomen, and legs light green;
except the anterior tibiæ, which are pale orange. Tail dark brown. Wings
of the same colour as on the upper side, immaculate. Wings entire.

The curious structure of the antennæ of this insect (which is, doubtless, peculiar to the males alone) is very similar to that of Desmia maculalis, (Westw. in Mag. Zool.) but the larger size, pearly wings, and different quarters of the globe in which these two species are found, make it doubtful whether the two insects belong strictly to the same subgenus. It is evidently nearly allied to the British genus Margaritia. Mr. Smeathman informed Drury that this is one of the Phalænæ which fly during the day. A little noise or rustling disturbs it, when it takes rapid flights of twenty or thirty yards, hiding itself with great ingenuity, which makes it difficult to catch.

HABITAT: China.

_Upper Side._ Head greyish brown. Antennæ strongly pectinated. Thorax and
abdomen greyish. Anterior wings with a bar rising near the middle of the
anterior margin, continued along the posterior wings parallel with the
external edges, and ending near the abdominal corners; the inner part
forming an equilateral triangle. The outer part of this triangle is ash
colour, the inner part pale brownish grey, but darker than the rest of
the wings. The tips of the superior wings are adorned with a small eye,
the lower part of which is black, and the upper part white; from whence a
faint white serpentine line runs to the very extremity of the wing. The
spaces between the ash colour mentioned above, and the external edges of
all the wings, are filled up with light brownish grey, appearing as if
powdered thinly with black dust. A small narrow black line runs along the
external edges of all the wings, which, beginning at the abdominal
corners and ending at the tips, appears as if broken or interrupted just
below the eyes. A narrow ash-coloured bar begins on the posterior edges
next the shoulders of the superior wings, which, running towards the
tips, suddenly turns off, and ends on the anterior edges about half an
inch from the shoulders. On the middle of the posterior wings is an
ash-coloured crescent, verged at top with black; and about a quarter of
an inch above this is another crescent, larger and much fainter, running
from the anterior to the abdominal edge, and ending at the extremity of
the body.

_Under Side._ All the parts on this side are nearly of the same colour as
on the upper, but not quite so distinct and bright. The angular bar on
the anterior wings next the shoulders, and the faint crescent on the
posterior, not being discernible. The margins of all the wings are
entire; the superior ones being hooked at their tips.

{13}From Dr. Roxburgh's interesting memoir upon the silk-producing moths of the East Indies,[1] it appears that this species is named the Arundi or Arrindy silk-worm, the caterpillars feeding upon the Arrindi, Ricinus, or Palma Christi. It is capable of being reared in the same way as the common silk-worm, the eggs are hatched in about ten or fifteen days; in about a month the caterpillars attain their full size, during which period they cast their skins three or four times. The caterpillar is from two and a half to three inches in length, each segment being furnished with several small soft conical tubercles, the prevailing colour being pale green. In this state they are very voracious, devouring daily many times their own weight of food. The cocoons are white or yellowish, of a very soft and delicate texture; in general about two or three inches in length, and three in circumference, and pointed at both ends. In this cocoon the chrysalis remains from ten to twenty days, the moth appearing at one end, the period of its final state not extending beyond from four to eight days. The moths are quiet, seldom attempting to fly from the apartment in which they are reared. The silk is so exceedingly delicate and flossy, that it is impracticable to wind it off; it is, therefore, spun like cotton, and the thread thus manufactured is woven into a coarse kind of white cloth, of a loose texture, but of surprising durability, the life of one person seldom being sufficient to wear out a garment made from it, the same piece descending from mother to daughter. It is used not only for clothing, but also for packing light clothes, &c. Some manufacturers in England to whom it was shewn seemed to think that it could be made here into shawls equal to any received from India.

{15}The Linnæan specific name of the type of the present genus was Papilio Idea, a name admirably expressive of the delicate transparent structure of these butterflies. As several closely-allied species were discovered in addition to the original type, all partaking of the same appearance, Fabricius transposed the original specific name into that of the genus; a new specific name, Agelia, being given to the original species, which is beautifully figured by Donovan, in his Insects of India, Pl. 24, and is by him considered identical with the insect figured by Drury. I have adopted the opinion of the authors of the Encyclopédie Méthodique, who consider the two insects as distinct.
