TO ZOOLOGISTS,

Ar the request of my friend Dr. Smith, I have undertaken to lay before the

public such Annulose forms collected by him in South Africa, as appear to be

most worthy of notice. It may be well that I should mention here my having

lately acquired, by purchase, the very extensive collection of Annulosa made

by M. Verreaux during his long residence at the Cape, and also his manu-

script notes on the species collected. Perhaps therefore no naturalist is

better provided than I am with those materials which are necessary to enable

us to form accurate notions of South African entomology. Upon this subject

also, my personal acquaintance with the habits of many exotic genera, may

to a certain degree be brought to bear.

In his descriptions of the vertebrated animals of the Cape, Dr. Smith has

adopted a plan of publication, which is at once convenient for himself and

for his readers. The subjects which he brings under the notice of natu-

ralists, are by reason of their size and importance in the economy of

nature, sufficiently interesting to entitle each species to a distinct plate and

a long description. He can, therefore, publish each animal in the order

that best suits his convenience, reserving for the conclusion his general

arrangement, when his readers can either adopt it or bind up the work

according to that system which may most please their fancy. I need

scarcely say that the expense which would inevitably result from the

adoption of any such mode of publication in the description of insects,

renders it impossible for me to follow Dr. Smith’s example. A whole

plate devoted to a single species of annulose animal, would be obviously

inconvenient for all parties, and to none more than to the purchasers of

this work. It becomes therefore necessary to place several figures in

one plate; the only valid objection to which plan is the difficulty of

finally arranging the plates according to system, since each of them must

necessarily contain figures of species that belong to very different groupes.

This evil, however, I shall endeavour to avoid, by describing as far as

2 t TO ZOOLOGISTS.

convenient, my species in small natural groupes, and by confining each plate

as much as possible to the representation of species that are nearly allied

to each other. Such a mode of proceeding, like that of Dr. Smith, will

allow of the work, when concluded, being bound up according to that system

of arrangement which may appear to the reader most advisable to follow.

I could wish that it had been in my power to describe these insects

according to the general plan commenced in the Annulosa Javanica. Several

circumstances, however, prevent such a scheme being followed, among

which is the necessity in a work of this kind of each number possessing

considerable variety. But although I am about to describe the Annulosa of

South Africa in a miscellaneous order, I trust no one will detect symptoms

of my being tormented by that morbid thirst for naming new species

which makes so many modern works in entomology, rather magazines of

undigested and insulated facts than harmonious histories of nature. It is

really distressing to see the philosophy of our science lost sight of in a

puling passion for that miserable immortality which is made to depend on

the invention of some barbarous technical names. We cannot even say

that the best entomologists are free from it, when we find the laborious

author of the “ Genera Curculionidum,” whose fame has arisen from his

study of nomenclature, shewing utter contempt of its laws. The pre-

servation of the earliest name is a duty not so much to the name as to

the science; yet M. Schonherr has in 1833, attempted to alter the names

of many genera published in 1825 in the appendix to Captain King’s voyage.

I shall not follow so mischievous an example; but as far as my humble

means will allow, I shall endeavour to be rigorously observant of that

leading principle of nomenclature which is the right of priority. This right,

in My opinion, is so necessary to be sustained, if we have any regard for the

interests of natural history, that I shall never for one moment wait to

consider whether the first namer of a species be an author of reputation

or not.

I.—ON THE CETONIIDA OF SOUTH AFRICA.

In 1819 I distinguished a family of Petalocerous insects, under the name of Cetoniide, that

had been originally marked out by Scopoli, as consisting of “ Scarabet Anthophili.” 1

shewed their affinity and analogies to the other Petalocerous families, and characterized the

eroupe by that membranaceous texture of the labrum and mandibles, which proves that these

insects in their perfect state are intended to live on vegetable juices; very few exceptions to this

general construction being known to exist in the family. [ also described two or three new

groupes belonging to the Cetoniide, but since that time many others have been named and

characterized, particularly by MM. Lepelletier and Audinet de Serville, in the 10th volume

of the Entomological part of the Encyclopédie, which was published in 1825. Mr. Kirby

also, in a paper read before the Linnean Society, in 1824; and in a number of the Zoo-

logical Journal, published in 1827, has given to the world some valuable remarks on certain

groupes of the family. But the work, which above all others, claims our present attention, is

the “ Monographie des Cétoines,’ commenced by MM. Gory and Percheron, in 1833, and

now, I believe, concluded. These gentlemen had the admirable intention of giving us in this

work a complete description, with figures, of all the species of Cetoniide—that is, of the family

as I circumscribed it in the Hore Entomologice. The grand defect of their monograph is

carelessness in the descriptions, in dates, and in names. Considerable reading and research

was necessary for their undertaking; but these authors appear to me to have scarcely ever

consulted any other entomological work than Count Dejean’s Catalogue. Although con-

stantly referring to me, they do not seem to be acquainted with any thing I have written;

nay, not even with that erroneous and somewhat piratical extract from my works, which in

1834 was printed in Paris, under the title of Annulosa Javanica. As for Mr. Kirby, they

are entirely ignorant of his labours; and although they often in like manner make mention

of his name, it is clear that they never read any of his instructive papers on the Cetoniide.

Another great defect of this French monograph consists in the figures, which are only on

a level with those of Olivier, and unaccountably bad, when we call to mind the beautiful

entomological plates now in the course of publication in France by M. Guerin, and in our

own country by Mr. Curtis. In short, the most praiseworthy circumstance connected with

the Monographie des Cétoines is the intention of its authors. This it is which makes the

book, with all its faults, a most useful work. It is truly the first entomological publication

which has a right to be called a monograph; as it is not either a local catalogue, or the

catalogue of one or two collections of a country, but professes to contain descriptions of all

4 ON THE CETONIIDA OF SOUTH AFRICA.

the species which the authors could procure a sight of, whether in England, or on the

continent. If it was a happy thought to undertake a catalogue of such extent, we the more

regret the way in which the undertaking has been executed. In fact, MM. Gory and

Percheron had every thing in their favor, except the acquirements necessary for the task.

The subjects of their monograph are large, handsome, and easily preserved. They were

therefore more likely to be brought from abroad than perhaps any other insects. The

Buprestide are also handsome insects, but as the species of this family often are very

minute, and always very active, so complete a collection of them is of more difficult

attainment. Indeed, we may fairly say, that with the exception perhaps of Central Africa, the

world contains of Cetontide few species unknown, at least in comparison with those which are

known. MM. Gory and Percheron appear never to have seen the noble collection made by my

father ; and if their work had been more ably executed, I should have deeply regretted my

absence from England at the time they were studying the museums of our Metropolis.

Nothing, however, affords me a better conception of the extent of their labours, than to see so

few generic forms, and even species in'my collection, which do not find their portraits, such

as they are, in the Monographie des Cétoines.

It will be easily understood, therefore, why I now commence with the description of

the Cetonide of South Africa. It is not only because the Cape of Good Hope is the richest

of all countries in the species of this beautiful family, but because every person who is in pos-

session of the Monographie des Cétoines may, to a certain degree, have the power of studying

analytically the affinities and analogies which I am about to explain, and of observing the

manner in which, I trust, the whole of organized nature will one day be wrought out.

I have also another object in commencing with the Cetoniide, which is, that having

been long sensible of the great confusion existing between the words genera, sub-genera,

sections, sub-sections, &c. 1 am naturally anxious to explain the meaning of these words, as

I shalJl in future use them.

Every one knows that sometimes sub-genera, and at other times even sub-sections of

genera, are in the most unphilosophical manner published as genera. Too often we find every

thing a genus which some gnathoclast, with Scapula in hand, has thought proper, in his good

pleasure, to call so. Some persons again there are, who on a first inspection can oracularly

decide that this groupe is a sub-genus, and that another groupe is of “full generic value.” To

such clearness of vision I can lay no claim; yet I cannot help thinking that there is a mode of

discovering the true subordination of these several kinds of groupes—nay, I am sure this

discovery will ever be the result of calm patience, of keeping before our view a great number

of the species of any family, and finally of following up that aphorism of a distinguished

botanist, which says, “ Omnis sectio naturalis circulum, per se clausum, exhibet.” When I

described the Geodephaga of the Annulosa Javanica, I had not that knowledge of a

sufficient number of the species, which was necessary to enable me to work out my sub-

ordinate groupes, and therefore I could only state that I did not exactly know which were

genera; and which were sub-genera. If any one, for instance, were to publish a complete

monograph of the Linnean genera Carabus and Cicindela, after the manner which MM. Gory

and Percheron have adopted for the Fabrician genus Cetonia, it might be possible for the

entomologist to distinguish the genera, sub-genera, sections, and sub-sections of G'eodephaga,

as well as to shew their reciprocal relations of affinity and analogy. That, however, which

most tends to prevent young naturalists from taking this, the most honourable path of

ON THE CETONIIDZ OF SOUTH AFRICA. 7)

entomological science, is impatience. It is impatience which makes them dislike the study

of affinities, which makes them delight in the grovelling task of making insulated descriptions

of new species, and idly fancy that harmony does not exist in the creation, because, forsooth,

they cannot immediately and intuitively perceive it. To this branch of natural history, indeed,

there is no royal road.

In order to exhibit the vagueness which hangs about the expressions — families,

genera, and sub-genera, I cannot do better than cite from one of our late periodicals, the

following words of an author: “These families which M. Wesmiel has since raised to sub-

genera, but which I consider of full generic value,’ &c. Here, the dispute obviously is,

whether a certain groupe be a family, a genus, or a sub-genus; and the first question that

presents itself to the mind is, what was the writer’s particular standard? He certainly seems

to have had some vague standard in his mind, for he talks of “full generic value.” But

has this value ever been accurately defined, either by himself, or any one else? Nay, has

the word genus any signification which is universally deemed definite? I fear in all such cases

‘of assertion, there is a latent disposition of the human mind to erect an arbitrary standard,

founded on the supposed value of some point of structure. Thus one person says that the

genera of Mammalia ought to be established on the differences in their system of dentition ;

and yet there are some genera of Mammalia where almost every species varies in the number

and form of its teeth; so that to adopt the rule, we must consider every species of such genera

to be a genus itself. Another person will tell us, like Linneus, that there are as many genera,

as aggregations of different species present similar constructions of some arbitrarily selected

organs, such as those of fructification in phenogamous plants, or the teeth in Mammalia. In

this sense it is evident that a genus may be made to signify any groupe whatever; as its

extent will depend on the nature of the structure selected. The black and yellow Cetonie of

South Africa will even form a genus, according to the Linnean definition of the word; and so

also will all vertebrated animals. Cuvier’s definition of a genus is, that it is a certain number

of beings so nearly allied, that they differ from each other only in the least important points of

their conformation— that is, specifically. A genus is, in fact, according to this naturalist, the

smallest natural groupe of species we can find. Such indeed is the idea of a genus which

prevails in the minds of most naturalists. We see every little groupe of species for which they

can discover’a character, immediately dubbed a genus; the absurdity of which is, that we

often find these very same persons again sub-dividing their “genera,” although, according to

their own definition, the groupes were already in rank only immediately above species. Even

Cuvier himself calls Sus a genus, or, in other words, according to his definition, a collection

of beings that only specifically differ from each other. Yet, inconsistently enough, he

proceeds to name and characterize a part of Sus under the name of Dicotyle, as a still smaller

groupe of species, and repeatedly makes mention of sub-genera.

Let me be understood on this head. I do not object to giving the name of genera to

sub-genera, nor that of sub-genera to sub-sections. The word genus may be applied as by

Linneus to mark out all Petalocerous insects, or as by M. Dejean to designate only the

Dorysceles of Madagascar. To either proceeding I have not the slightest objection; if we

only understand each other, and that the word genus is to have a similar value in all cases.

It is not to be defined the smallest possible groupe of species here, and in another place

considered as a groupe which contains many other groupes of species. This cannot be a

correct mode of using the word; although it may, from our ignorance of created species,

6 ON THE CETONIIDE OF SOUTH AFRICA.

appear sometimes to be consonant with what we observe in nature. If we divide all animals

into sub-kingdoms, classes, orders, tribes, stirpes, families, genera, sub-genera, sections, sub-

sections, &c. &c. or any other names, we must not confound all these groupes together, but

during our investigations, preserve each of them in that proper subordination which may

have been agreed upon by naturalists. But here some one may observe that all groupes are

arbitrary and artificial, since after all they must depend on the selection and good pleasure

of man. To this I answer that affinities are natural; and if all these affinities are expressed

by any mode of grouping, it follows also that the groupes must be natural; although,

certainly, these last must in some degree have depended on our selection. But in fact,

these groupes are only chosen because they coincide with the affinities which exist in nature.

Our grand object, when we are trying to find out a natural arrangement, is not to give

an arbitrary value to particular characters ; but to express all the relations, whether of affinity

or analogy, which may exist in the branch of natural history we study. If these relations are

all indicated by the arrangement, our object is gained; and it can be no objection whatever

to the system, that in our pursuance of an eclectic plan, a character which at one time we

set a value upon, is at another time esteemed of little worth. Indeed, it is obvious in every

part of natural history, that the most important characters break down in certain species,

and become at times perfectly worthless. Comparatively constant as is the structure of the

teeth in the genera of Mammalia generally, we find in some groupes, such as the Edentata,

or the genus Rhinoceros, that the dentition varies extensively in almost every species. Again,

in Botany, how steady is the dicotyledonous character of Exogenous plants; yet we have even

this most important distinction breaking down in certain families. One naturalist arranges

animals according to their brain and nervous system; another tells us, he prefers their

osteology, and so on. Each point of structure, being of the utmost consequence to animal

economy, is concluded by its peculiar partisan to be therefore infallible as a ground of arrange-

ment. Very little experience, however, is sufficient to shew that each of these favorite hobbies

is unsafe to ride upon; and we are in our search for an accurate way of expressing the relations

which connect various beings, obliged to adopt another plan of calculating the value of

principles of arrangement.

My plan, as is well known, has ever been not to estimate the value of any arrangement

by the value in animal economy of the structure upon which this arrangement is founded, but

to make the importance of every organ or structure for purposes of arrangement, rise in inverse

proportion to its degree of variation. The consequence of this rule of procedure, has been

the birth of an arrangement which is universally applicable. And yet, even this rule is

nothing more than an abstract measure of the importance of some individual character in the

arrangement of that particular groupe, where we may happen to make use of it. It is a

rule, moreover, that we cannot always with safety put in practice; for although with respect

to arrangement, it is ever an admirable instrument of correction, it is sometimes also a

dangerous one’ of discovery. Indeed, in discovering natural arrangement, we can never safely

swerve from the Linnean axiom, which although it alludes more immediately to “genera,”

holds good equally of all groupes; “Scias characterem non constituere genus sed genus

characterem, et characterem non esse ut genus fiat sed ut genus noscatur.” We truly make

use of a process of tatonnement. We do not argue that such must be the groupe, because

such and such are, in our opinion, good and distinct characters; but we say, such happens to

be the character, of no matter what importance, which prevails throughout the groupe, and

ON THE CETONIIDE OF SOUTH AFRICA. 7

which seryes in some degree to insulate it from other groupes. But it is evident that we

must previously have arrived at the knowledge of the groupe; and this is effected by a close

watching of the variation of affinity, and by considering the groupe to be complete only when

the series of natural objects returns into itself. It is more particularly when we have satisfac-

torily applied this test of the groupe’s completeness, that we ought to look out for its natural

character. Still, after all, we may be wrong; we may sometimes imagine a groupe to return

into itself, when it does not; or we may consider what in reality are two groupes, to form

only one. The best way I know of correcting such evils, is to recollect that the natural

system ought to express all the relations which exist between the various objects of our

study, and that if any of these are left unrepresented in our arrangement, there must be

some latent error, in the formation of our groupes. I repeat, that the process is one of

tatonnement. The marsupial animals have clearly some kind of relation to Primates, to

Insectivorous Fere, to Edentata, and also to Glires. Now, if a naturalist cannot express all

these relations, and at the same time all the various relations which exist among the other

eroupes of Mammalia, he ought to be convinced that his arrangement is wrong. It is of

no use to talk about the importance of this organ, or of that other, in the structure of

these animals. If even we were right in any such comparative estimate of the importance of

organs in general economy, we ought not to forget that the true question under consideration

is, the natural arrangement of the animals themselves; and that this is to be attained only

by the expression of every affinity, and every analogy that can be detected. The unnatural

groupe Zestacea, was founded on the important character of the presence of a shell; and we

shall see among the Cetoniide, that genera were erroneously separated from this family

because they wanted its leading characters, which consist in the membranaceous texture of

certain parts of the mouth.

I have before alluded to the fact, that when a series of affinity is followed, it is observed

to return into itself, and thus to form a closed groupe. Now, if we start from the principle

that when a few species first agree in some particular character, they combine into a series

that will return into itself, we shall probably imagine every such series, so forming a circle

in practice, to be in theory the first natural assemblage of species. Yet this will be an

incorrect mode of viewing the matter ; for owing to the rarity of its species, the first known

circular grouping of the species of Cryptodinus, for instance, is mto sub-genera; whereas

the first known circular grouping of the species of Cetoniide is into certain sub-sections.

But, if the above hypothesis were true, the sub-genera of one genus would be equivalent

in value to only sub-sections of the other. I conceive, therefore, that m order to attam

accuracy in the distinction of groupes, we must proceed in a totally different manner to

investigate the subject. In the first place, we must commence from some given point in

which all naturalists agree. Such a point undoubtedly is the animal kingdom. Every one

acknowledges this groupe. Now I observe the animal kingdom to resolve itself into five

natural groupes, forming a circle. I observe again, each of these circular groupes to resolve

itself into five others, and so down, until I arrive at species. Now it is clear that I may

term the animal kingdom a genus, or I may call the groupe Vertebrata a sub-genus, and

Mammalia a kingdom; the word given as a name to the class of groupe, being adopted

for convenience, and being merely conventional. My aim is not to dispute about the

propriety of the names given to these various groupes, but merely to express the proper

subordination of one groupe to another, even supposing that they had no names. If, therefore,

8 ON THE CETONIIDE OF SOUTH AFRICA.

I say that I will call the first five divisions of the animal kingdom, sub-kingdoms or provinces ;

the second 25 divisions of these, classes; the third 125, orders; the fourth 625, tribes; the

fifth 3125, stirpes or races ; the sixth 15625, families ; the seventh number of circles, genera ;

the eighth sub-genera ; and the ninth sections; and the tenth sub-sections, &c. &c.* we

shall obtain one general rule for the Annulose creation, and at least obtain the great advantage

of understanding definitively what we are talking about. Theoretical, and to a certain degree

artificial, as this view of the matter may be, it will assuredly tend to clear up our practice.

It may indeed be urged that difficulty occurs with respect to what are called insulated

species. A Cryptodinus is more insulated than a Cetoninus, and an Hippopotamus than a

mouse. ‘This is true; but then I understand that the genus Cryptodinus, were it more

perfect, ought to contain as many groupes of species as Cetoninus is known to do, and that to

comprehend perfectly the affinities of a Hippopotamus, we must suppose it to be immediately

surrounded with as many sections, sub-genera, and genera, as are known immediately to

surround the mouse.

Thus, when the naturalist talks of any anomalous structure, J understand merely that

so many links, that is, so many groupes, of the great plan of creation are wanting, as

would connect this smgular being with some other and better known form. If I say that the

Hippopotamus forms a stirps by itself, I only mean that it is the sole species of its stirps

known; and that, speaking theoretically, four families are wanting, or rather twenty-four

genera to connect it well with the other tribes of Pachyderms. It is of no consequence

whether the families and genera supposed according to this theory to be wanting, have

disappeared, or whether they have never been created. I merely suppose them to be

wanting, in order that I may obtain something like a just notion of the relation which the

Hippopotamus bears to the other Pachyderms.

Tt will be seen on a review of the preceding remarks, that Cuvier’s definition of a

genus above given, most truly answers to what in the following observations on the

Cetoniide I shall call sub-sections, or even to still smaller groupes, if any such can be

pointed out; and that if genera are found to contain sometimes a few beings only specifically

differing from each other, this results from our ignorance of certain sub-genera, sections, and

sub-sections that are wanting. To those persons who may choose to give the name of

genera to the entomological groupes which I call sub-sections, I have only to say that they

ought to do it in all cases. They have no right to call the groupe named Cetonia by

MM. Gory and Percheron, a genus, and also that which is termed by those gentlemen

“ Dicheros.” 1 have avoided this confusion in entomology,} by invariably considering genera

to be that sub-division of the animal kingdom which is the seventh in degree downwards;

that is, to be the first sub-division of families.

In the same way that we discover confusion to proceed from that definition of genera

which asserts them to be the next class of groupe above species, we shall also find a certain

degree of confusion to proceed from the definition of the word Family, as depending on

* Some persons have imagined that I only assign five species to the lowest groupe in nature ; but the above theory

evidently proceeds on the assumption that if we knew all the species of the creation, their number would be infinite,

or in other words, that they would pass into each other by infinitely small differences. This actually takes place

sometimes in nature; and as yet I do not know any good distinction between a species and what is called ‘‘ a permanent

variety.”’

+ I suspect that genera among the Vertebrata may, from the comparative paucity of species, conveniently be considered as

standing one degree higher in the scale, or in other words, that we may in that sub-kingdom, neglect the use of the word stirpes.

ON THE CETONIID OF SOUTH AFRICA. 9

the above awkward one of genera. A family, in entomology, is held to be the next groupe

in rank above genera ; as, indeed, I myself consider it. I only differ from others in the value of

the word genera. What, for instance, is the consequence if Cuvier’s definition of genera be

adopted? A most natural groupe has been marked out, and distinguished under the name

of Cetoniide. In process of time some naturalist discovers within it other combinations of

groupes which he considers genera, because, so far as he knows, they are the first groupes

of species. Gnorimus, for instance, is such a groupe of species. Our naturalist forthwith

calls it a genus: and he observes, that a number of such genera combine to form another

groupe, which he calls Trichiide. Of course, he makes this combination of “ genera”’ a family ;

and knowing that it cannot possibly be of the same rank as the original family of which it

only forms a part, he is obliged to change the name of this from Cetoniide to Melitophile.

It is thus that we have now every day such “ families” formed as Sericide, Diplotaxide, ke.,

excellent groupes perhaps in themselves, but which their authors have been led away by a mere

love of changing names, to consider as equivalent in rank to true families, such as Trogide

and Rutelide. Any person gifted with a pair of eyes can analyse. The difficulty is to

employ synthesis. In botany, every fraction of the ancient families has in like manner been

also called a family, and the consequent confusion arrived at such a pitch, that Bartling

and Lindley have lately been obliged to attempt the re-grouping, if I may so express myself,

of the modern small “families” of plants. I have in the following observations on the

Cetoniide, also endeavoured to avoid this confusion, and to preserve consistency ; first, by

considering such new-fangled families, as the “ Trichiade,” “ Sericide,’ “ Diplotaxide,”

“ Goliathide,”’ kc. to be only genera or sub-genera, containing minor groupes of species; and,

secondly, by keeping them in proper subordination to their original families, the Cetoniide, Melo-

lonthide, &c. ‘These last, as families, I also agree to be the next groupes above genera, once that

I have conveniently defined families to be the sixth degree of groupe downwards from the

animal kingdom. Having said this much, I am ready to allow in behalf of those who are so

fond of imposing new names on the science, at whatever expense of confusion, that if, for instance,

a sub-section of Goliathus like that which is called Mecynorhina, by my friend Mr. Hope,

be considered a genus, it follows, that the next groupe above it, and of which Mecynorhina

forms a part,—viz. the groupe which I call Smithii, may, without blame, be called a family.

But then such a family would be the ninth degree of groupe downwards from the animal kingdom.

In order to exhibit clearly the place of the Cetoniide in nature, I shall now give the

following series of groupes.

Regnum, ANIMALIA.

1. Subregnum, ANNULOSA.

2. Classis, MANDIBULATA.

3. Ordo, COLEOPTERA.

4. Tribus, CHILOGNATHOMORPHA.

5. Stirps, PETALOCERA, THALEROPHAGA.

6. Familia, CETONIID.

Although I observe that of late various entomologists of great reputation have been

designating families without venturing to give characters to them, I shall not follow their

example; since I consider no name of the least weight that has not some character

attached to it, enabling us to discover the accurate limits of the groupe which that

name designates. It may be true that we have not always the good fortune to alight on the

10 ON THE CETONIIDZ OF SOUTH AFRICA.

real character which insulates the groupe, but this is a venial defect, into which every

naturalist is, at times, liable to fall. Mr. Vigors, for instance, discovered and pointed out

the natural groupe of Jnsessores among birds; but their true characteristic was not known

until I observed that these are the only birds which have “callow” young.

Fam. CETONIIDA, Mihi.

Antenne of ten joints (very rarely nine), terminating in a triphyllous club composed of the

three last joints.

Labrum compressed, generally membranaceous, often emarginate, with rounded comers, and

always concealed under the clypeus.

Mandibles in general compressed, and furnished on the inside at the base with a subquadrate

membrane, while the base and produced outer side are corneous.

Maxille ecorneous, and rather of a prismatic form, having their inner side often membra-

naceous, and fringed with hairs, but sometimes corneous, and armed with teeth.

Maxillary Palpi of four joints, the first joint being often evanescent, and the last never

compressed.

Labium and Mentum more or less confluent, sometimes completely so; and the mentum is

anteriorly truncated or emarginated, but never trilobed.

Head often subquadrate. Body always winged, and in general depressed. Feet in

general slender, with the fore tibie for the most part dentated, more particularly

in the females. Tarst pentamerous, terminating in two equal sharp undivided

claws, between which often intervene a plantula and pseudonychia.

1. This family consists, to my knowledge, of more than 600 species, of which only five are

natives of Great Britain. The groupe has been most erroneously characterized by MM. Gory

and Percheron. These gentlemen distinguish the “ Scarabées Melitophiles,’—a name, be it

observed, which although Latreillian, is very erroneous,—by the mandibles being rudimentary,

or even by these organs of the mouth being altogether absent. A description so anomalous

of Cetoniide, in a work entirely devoted to them, is not very creditable to these gentlemen

as entomologists ; since I need scarcely say, that the mandibles are never absent. ‘True it is

that in general these organs are compressed, and often even extremely thin and membrana-

ceous; but sometimes again, as in the Macroma scutellaris, G. P., and Cryptodus para-

doxus, M‘L., &c. the mandibles and maxille are as solid, thick, and corneous, as in any

Melolonthidous insect of equal size.

2. The Cetoniide pass off to the Gilaphyride on one side, and to the Rutelide on

the other. Those species of the sub-genus Trichius, which Mr. Kirby has called Archimediz,

shew us that by the Trichius lineatus, Fab. (Lepitrix lineatus, Lp. Sr.) an insect of the Cape,

we may arrive among the Glaphyride; and Mr. Kirby has, by the description of his genus

Cnemida, explained to us how we may also pass from Macroma to the family of Rutelide.

While on this subject, I may express my regret that an entomologist so distinguished as M.

Dejean, and who has merely named this and other species in his catalogue without describing

them, should have endeavoured to set aside the name Cnemida Curtisii, which Mr. Kirby has

given with a description. The right of priority in entomology is usually held sacred, yet

Cnemida Curtisii, K.is called C. crassipes by Dejean without any assigned reason. Itis unfortu-

nate for Mr. Kirby that he should so often have.set the example of reckless change to foreigners.

ON THE CETONIIDZ OF SOUTH AFRICA. il

3. Mr. Kirby, in the 14th volume of the Linnean Transactions, -following perhaps an opinion

I had thrown out on the Hore Entomologice, appears to consider Chasmodia, M‘L., to be

close in affinity to the Cetonizde. But the relation of Chasmodia to Lomaptera, G. P., is one

of analogy: the two groupes being corresponding points of contiguous families. Both are pol-

lenivorous groupes, agreeing in brilliancy of colour, and in their cleft clypeus ; but in no essen-

tial respect are they so constructed that they can be brought close together in affinity.

4, In some species of the Cetoniide the tergum of the prothorax (which shall, in my obser-

vations on this family hereafter, be generally called thorax, for convenience and in conformity to

the vulgar notion) is apt to have the middle part produced behind into a lamimar lobe, which

covers the scutellum in a greater or less degree. In proportion as this structure occurs,

we always find the insect to be more sluggish and inactive. Thus the insects which compose

the American subgenus Gymnetis are incomparably more sluggish in their habits than our

European Cetonie.

5. M. Dufour has given us the anatomy of the perfect insect of the well-known English

species Cetonia aurata, Fab. ; and Professor Dehaan has favoured us with the anatomy of its

larva. I shall in this place only observe, that the internal anatomy of the insects of this family

is subject to greater variation than their external anatomy; and it must therefore be more

distrusted in classification, according to the principles I have ventured to lay down in the 14th

volume of the Linnean Transactions.

6. In the following enumeration of the various groupes into which the Cetoniide have been

broken up, I shall endeavour to be strictly just in assigning them to their proper disco-

verers. From the respect due to the labours of my predecessors, I shall try to retain every

name that has been published ; but I would have it here clearly understood, that the name of

the author annexed to a technical word does not always signify that he invented that name,

but rather indicates the particular value given by that person to the groupe. ‘Thus, for

instance, Trichinus, Fab., will indicate the groupe called Trichius by Fabricius; and Trichius,

M‘L.; the value given to the Fabrician name by myself. The discoverer of a natural groupe

may have some merit, but the mere inventor of a name has really none. On this principle,

therefore, I have generally acted ; and more particularly when, in order to distinguish genera

from sub-genera, I have given the former a termination always in inus.

12 ON THE CETONIIDZ OF SOUTH AFRICA.

7. I term these genera, because they are the first class of groupes into which the

Cetoniide resolve themselves. ‘They form a series returning into itself. Some persons may call

them sub-families, or give them any other name. This is quite a matter of taste; but I choose

to call them genera, in order that I may more easily hereafter shew the relation borne to

each of them by the groupes of modern entomologists. Of these genera then, Trichinus

appears to have been discovered by Fabricius, and to answer tolerably well to his genus

Trichius. I have therefore assigned the groupe Trichinus to him, because Vrichius denotes,

with modern authors, a groupe of more limited extent. Cryptodinus and Macrominus are

groupes now, I believe, for the first time, clearly pointed out, although the former nearly

corresponds with what Gory calls his genus Cremastocheilus. I have assigned the groupe

Gymnetinus to Kirby, because it answers very nearly in extent to the sub-family called by him

Gymnetide, and by Gory Gymnetides. Cetoninus is a groupe which I am not aware-has ever

until now been properly distinguished.

8. I am acquainted with larve of the genera Trichinus, Gymnetinus, and Cetoninus ; but I

believe no larva of Cryptodinus or Macrominus is as yet known. It is probable, however,

that the larve of these last, when discovered, will be found to have the mandibles formed like

those of the larve of Osmoderma eremita, that is, unidentate at the extremity ; for they are

insects which have great affinity to each other in the manners of their perfect state.

9. I have attempted in the above table to distinguish the normal groupe by its larva; but it

may also be not badly distinguished by the imago, which has the terminal process of the

maxilla almost always without teeth, and, at the same time, the epimeron almost always appa-

rent between the angles of the thorax and elytra. By the first of these characters the normal

groupe may be separated very nearly from the genus Macrominus, and by the latter very

nearly from the genus Trichinus. There are exceptions to the rule, such as Philistina and a

section of Goliathus, which have maxilla with corneous teeth, and Jnca, which has the

epimeron not apparent between the thorax and elytra; but these are osculant groupes, the

former leading to Macrominus, and the latter to Trichinus.

10. Of the five British species that belong to the family of Cetoniide, three are to be

assigned to the genus Zrichinus, and two to Cetoninus. But no one who confines his atten-

tion to the above five species can form any notion of the beauty and variety of form that

prevails throughout the family.

11. Ido not venture to alter the terminations of the sub-genera, in order that they may

agree with that of the genus to which they belong; nor can I make the terminations of the

genus apply to that of all the sub-genera which it contains. The consequence of this is, that

we have often strange concords, such as Trichinus Platygenia Zairica; but in such cases I

have always made the trivial name agree with the sub-genus rather than with the genus. To

this last I have given the termination, which corresponds with that of the majority of the

sub-genera.

Genus I. TRICHINUS, Fab.

12. This genus is easily known from Cryptodinus, M‘L. by its flat mentum and maxille

provided with a brush of hairs; while from the genus Cetoninus, it is separated by its never

having the epimeron prominent between the thorax and elytra, as well as by the anterior femora

having no spines at their junction with the tibie. Ido not place so much confidence in

Latreille’s character drawn from the mode in which the labial palpi are inserted.

ON THE CETONIIDE OF SOUTH AFRICA. 13

13. In this genus, generally, the terminal brush of the maxilla is inserted in the triangular

orifice of a short triangular corneous process, which terminates the maxilla, and appears articu-

lated to it. In some of the floral species, this pencil of hairs or brush is very long, and admirably

calculated for sucking up the honey of flowers; but in other sub-genera, such as Platygenia

for example, the terminal brush may rather be considered to line the edge of the small trian-

gular corneous process which terminates the maxilla and appears articulated with it. In such

insects this process of the maxilla is not so palpiform as in those Trichini which inhabit flowers.

14. The larva and metamorphosis of the sub-genus Jrichinus have been perfectly well

explained by Professor Dehaan of Leyden, who shews that they bear more similarity to those

of Glaphyride and Melolonthide, than to those of the sub-genus Cetonia. This is a curious

fact, and strongly illustrative of the danger attendant on our assuming a method of division

instead of following the mode of variation. What groundwork for a natural division, for

instance, appears more natural than metamorphosis? Certainly none; and yet if we divide

the family of Cetoniide by this rule, we shall place half of the contents along with the

genus JMelolontha! If, on the other hand, we follow the maxim of variation, and watch

how the metamorphosis changes, we only arrive at the fact, that Trichinus (i.e. an aberrant

genus of Cetoniide) is intermediate between the Glaphyride and the typical Cetoniide,

inasmuch as it has the larva of the former, and the imago of the latter.

But we proceed to detail the various sub-genera of Trichinus. Fabricius was not acquainted

with the singular insects which compose the first of them.

Sub-genus 1. Puaryeunta, M‘L.

15. Of this sub-genus only one species is certainly known; although, to say the truth,

Gory’s figure of what he calls Platygenia Zairica, is so unlike the insect which I so named

some years ago, that one is almost inclined to believe he may have fallen accidentally upon

a new species of the groupe. Indeed, I consider the Trichius barbatus of Schonherr to

belong certainly to the sub-genus. The mouth of Platygenia approaches very near in

structure to that of Osmoderma, however different it may seem in external appearance. It

is in fact, the mouth of an Osmoderma, with all the parts flattened, and excessively

widened, differing only in having the terminal lobe of the maxille transversal and small. I

imagine, indeed, that the true character of this sub-genus is founded on the comparative

evanescence of the palpiform terminal process of the maxille.

16. The general form of the thorax of Platygenia, and its very depressed body, make me

think that we can proceed from it to Campulipus, by means of some sections hitherto

14 ON THE CETONIID OF SOUTH AFRICA.

unknown. M. Latreille perceived this affinity; but we only know one section of Platy-

genia, and consequently, must reckon several forms wanting before we can closely connect

it with Campulipus. Both are sub-genera peculiar to Africa.

Sub-genus 2. Campuuipus, Kirby.

17, This groupe agrees with the last, and differs from all the other sub-genera of Trichinus

in having its body depressed, and the four joints of the maxillary palpus distinct. The

elytra also nearly cover the podex, and the terminal process of the maxilla is very long,

so as sometimes to resemble that of a bee. These are most likely floral insects. The

following sections appear to be known.

B.—Body more convex. 5 4 Myoprrmt, Dej. Clypeus not simple.

L5 Zeprz1, M‘L. Clypeus simple.

18. I have given the credit of this sub-genus to Mr. Kirby, but m fact his Campulipus is

a groupe which only answers to the normal groupe of this sub-genus as above characterized.

Mr. Kirby first observed Trichius limbatus of Olivier to be distinguished from its congeners

by the remarkable intermediate tibie, which are curved into an obtuse angle, and appear

thus as if broken. This character, however, is still more developed in an undescribed species

in my collection, of M. Gory’s singularly-named genus* Stripsypher, which species I shall

here call Campulipus incurvatus. It is black, with yellow elytra, having four square black

spots. This incurvation of the intermediate tibize appears to be a sexual character, for I

possess a specimen of Campulipus limbatus, without this distinction being strongly marked.

Of the section AcEni1, we have the following from the Cape.

“Sp. 1. (Trichinus) Campulipus limbatus, Ol.

Agenius limbatus, G. P. p. 95. tab. 11. fig. 4.

Nors. I may here remark that the figure of the mentum and maxilla of Agenius limbatus as given by

Gory is all wrong. The mentum comes much nearer to that of his groupe Stripsypher, and the maxille

in both sections have a long penicilliform terminal process.

Nore. Campulipus Horsfieldii is a beautiful species which appears to connect the two sections, AGENII

and SrripsyPHEeri. Stripsypher niger, G. P. a Cape insect, truly belongs to the section STRIPSYPHERI.

Yet, while the Agenii belong truly to Southern Africa, the SrrresypHERI are found more in the intra-

tropical regions of that vast continent. As to the section which I have named Myoprrmi, and which

corresponds with the genus Myoderma of Dejean’s Catalogue, I only know it by M. Gory’s bad figure

and worse description of “ Stripsypher sordidus,” which comes from Senegal.

Of the section ZEBRzI we have one species at the Cape.

Schénherr, and in his plates 8. 6-maculatus is neither. It is called by Schonherr Trichius 6-guitatus.

Sub-genus 3. Tricurus, M‘L.

19. This may be known from Campulipus by having a much shorter palpiform process to

the termination of the maxille, as well as by the podex being in general more covered by the

elytra. It has also a more convex form, and thus it may be distinguished from the sub-genus

Valgus, as well as by its longer elytra. Trichius haunts flowers, and may be found in

Great Britain. It is the sub-genus which passes off to the Glaphyride.

20. Under the name of “ Lucirimt1,” I have included Mr. Kirby’s two sections, “ Legitimi”’

and Trichini, which last he now terms a sub-genus. The evanescent difference between

these two groupes of the reverend gentleman appears to be of a very low order, and probably,

therefore, only indicates sub-sections. Indeed, it chiefly consists in his Trichini bemg

nitid and zneous, and his Legitimi not. However, Mr. Kirby thinks he can discover some

slight difference in the last joint of the palpi. The type of the section I have termed Lzeirim1

is the well-known Trichius fasciatus of Fabricius. Mr. Kirby makes the type of his section

AxzEurosticti to be Trichius nobilis of Fabricius. This last section is, therefore, identical

with the groupe called G'norimus in the “ Encyclopédie,’ by MM. Lepelletier and Serville.

21. Under the name of Gzomurrict, I have included Mr. Kirby’s two sections Archimedii

and Enclhdii, because there is, in my opinion, no sufficient difference between them to

entitle them to be made distinct sections of the sub-genus. They may, however, ultimately

prove to be distinct sub-sections of the section G‘eometrict. I consider the type of the

Geometrici to be Trichius delta of Fabricius.

22. Of the section TeTRopHTHALMI, as distinguished by Kirby, we have among the insects

collected by Dr. Smith, the following species.

Sp. 4, (Trichinus) Trichius vittatus, Fad.

Trichius suturalis, G. P. p. 84. tab. 9. fig. 6.

16 ON THE CETONIIDEA OF SOUTH AFRICA,

Sub-genus 4. Vauteus, Scriba.

23. This answers to the genus Acanthurus of Kirby, easily known by its depressed form,

long trapezoidal prothorax, and short elytra. In the only section of this sub-genus which

I know, there is a mucro arming the anus in one of the sexes, and which is probably the

ovipositor. I have always found the species of Valgus, either at the roots of trees, or at the

foot of walls, but never on flowers as Latreille says that he has found them. The section

Geometrici of the last sub-genus is covered with scales, and so is this sub-genus ; but we still

want some sections of Valgus to connect the Geometrici with the common Trichius hemipterus

of Fabricius. Indeed, I am not aware that the present sub-genus has ever been resolved into

sections. There is one species at the Cape, viz.

Sp. 6. (Trichinus) Valgus Smithii, x. s.

Duscr. Valgus thoracé postice utrinque macula nigra abdominisque fascia alba.

Lone. Corp. 4 lines.

Nore. This species is scarcely distinct from the Valgus hemipterus of Europe. It has the same ruge

of the thorax, the same size and general form, and only differs slightly in the disposition of the scales,

In V. hemipterus for instance, the abdomen is quite white with thickly set scales. In V. Simithii there is

merely a white band. V. Smithii has also a white mark in the black lateral spot of the thorax. But in

truth these species come very near to each other.

Sub-genus 5. OsmopERMAa, Lp. Sr.

24. This groupe has been hitherto described and figured with little care. It is said to

lave the terminal lobe of its maxille corneous. This lobe is not, however, more corneous than

in any of the other sub-genera of Trichinus. It is an elongated hollow triangle, filled with a

short thick pencil of hairs. The true characteristic of the sub-genus is the strong corneous

hook which arms the maxille on its inner side. These insects live with their larve in rotten

wood. They have been called Gymnodi by Mr. Kirby, and made by him part of his genus

Trichius. 1 am acquainted with two sections of Osmoderma, which are peculiar to Europe

and North America. The type is Trichius Eremita of Fabricius. I have already said that,

different as Platygenia Zairica is in aspect from all the other known species of the genus

Trichinus, it comes in every essential respect exceedingly close to Osmoderma. I suppose the

name given by Lepelletier and Serville to this sub-genus, alludes to the scent of Russia

leather, which the European species O. Hremita emits when it is handled.

Genus II. CRYPTODINUS, Mihi.

25. We have seen that none of the known species of the genus 7richinus have the terminal

lobe of their maxille furnished with teeth. The sub-genus Osmoderma, was indeed sup-

posed to possess this structure, but erroneously; although it has certainly a tooth at the

point of the mner process. This formation appears to prepare us for the maxille of the

present genus Cryptodinus, of which the character is always to have a corneous tooth or

teeth on the terminal process. Indeed, that tooth which Osmoderma possesses on the inner

process of the maxille, brings it, of all the sub-genera of Zrichinus, the nearest to the genus

Cryptodinus. This genus may be always known by its depressed elongated form, and by

the under side of the mentum having a process, while the outer side of the terminal process

of the maxilla has no brush. Cryptodini are found in all the principal divisions of the

globe, Europe excepted. They are nevertheless chiefly intratropical insects, which are

great lovers of sand on the banks of rivers, and so far as my observation has gone, they are

not authobious. This genus is nearly the same in extent as the genus Cremastocheilus of

Gory and Percheron, and is easily known by the first joint of the antenne being large,

triangular, and broad. I am acquainted with the following sub-genera.

26. All the foregoing five sub-genera agree in the clypeus having a reflexed margin in

front. They agree also in the curiously dilated triangular scape of the antenne, and in the

epimeron not being prominently distinct between the thorax and shoulders of the elytra.

Sub-genus 1. CremastocHsitus, Knoch.

27. This groupe answers to the genus Cremastochetilus of Knoch, Latreille, and Kirby ; but

it is here reduced to its proper rank, that of a sub-genus only. It differs from the other

sub-genera in having the vertical process of the mentum hollow, and basin-shaped, while the

terminal process of the short maxilla, is a straight blunt tooth, and the inner process is a sharp

minute tooth surrounded with a few hairs, These insects are North American, and differ

in their manners from the Cetoniide in general, but probably agree in this respect with all

the other sub-genera of Cryptodinus. The species of Cremastocheilus are not common. In

company with Dr. Pickering, and Mr. Titian Peale, I found C. castanee of Knoch, in

June, 1836, on the banks of the Delaware, on the new J ersey side, opposite to Philadelphia.

These singular beetles are never found except flying, like Cicindele, over the sand which there

lines the bank of that noble river. They are certainly not flower-frequenting insects, and

what they find in the sand to their taste J do not know. Mr. Kirby has made some

good remarks on this sub-genus in the third volume of the Zoological Journal ; only without

giving any sufficient reason for so doing, he has termed that part the labiwm which Latreille

has called the mentum. Iam not acquainted with the sections into which Cremastocheilus

may be divided.

Sub-genus 2. Cycrrpius, M‘L.

28. To this groupe belongs C. elongatus of Olivier, and C. axillaris of Dupont. I shall add

another species which stands in my cabinet as C. Nero. It is as large as Platygenia Zairica,

and of a velvetty black hue, with two large long nitid and blood-coloured spots in the middle

18 ON THE CETONIIDE OF SOUTH AFRICA.

and towards the apex of the smooth and perfectly flat elytra. It is the giant of the genus

Cryptodinus. The sub-genus Cyclidius, appears to be peculiar to South America.

Sub-genus 3. Genucuus, Kirby.

29. MM. Gory and Percheron do not adopt this groupe, and in their usual self-sufficient

way, state that I first separated it from Cremastocheilus, and that I have erroneously charac-

terised it. To this I answer, that never until now, have I published a word on the subject.

It is true that Mr. Kirby, who instituted the sub-genus in the Linnean Transactions,

erroneously characterised it by saying that the maxille are membranaceous. But it is

truly, nevertheless, a natural groupe, and differs from the North American sub-genus Cre-

mastocheilus, with which Gory and Percheron confound it, not only in having the mentum not

hollowed out, but also in having the maxilla composed of two sharp round claws, the larger

one being exterior, and answering to the terminal process in the Cetoniide generally. The

truth is, that these French critics know nothing of Mr. Kirby’s groupe Genuchus, except

that in Dejean’s Catalogue, apparently their only work of reference, the Cetonia cruenta

of Olivier, is assigned to “ Genucus of Macleay.” I am unacquainted with the cause of

this, and of a myriad of smaller errors mixed up with my name in Dejean’s Catalogue; but

MM. Gory and Percheron copy the mistake even to the cacography of “ Gienucus ;” and thus

appear, when writing a monograph on the Cetoniide, to have never consulted any of

Mr. Kirby’s writings on the subject, although some of them are printed in so well known

a publication as the Transactions of the Linnean Society. But to proceed. The sub-

genus Genuchus is, so far as I know, entirely African, and Afzelius says that the species are

always found on the ground like Aphodii. Dr. Smith has brought two species to Europe.

30. Cremastocheilus. capensis, of Klug, and several other African species, particularly

from Senegal, belong to the sub-genus Genuchus, of which there are several sections known.

I am not acquainted with the C. Brahma of Gory and Percheron, but I know their Cre-

mastochetlus maculatus, which I suspect will be found eventually to enter the genus Macrominus.

Their bad figure and description of this last-mentioned species, make it come far too close to

the Cetonia maculata of Fabricius, which insect, by the way, is not a native of the Cape,

as they say, but of the Mauritius.

Sub-genus 4. Cymopnorvs, Kirby.

31. I have never seen any species of this groupe which is the genus Cymophorus of

Mr. Kirby. It is the only sub-genus of Cetontide which I do not possess. Judging,

however, from Mr. Kirby’s description and figure of the Cymophorus undatus, the insect

appears to come into this place. We may, perhaps, associate with it the Cremastocheilus

spiniventer of Gory, in which case it would appear to be an African form of the genus

Cryptodinus. 1 suspect it, nevertheless, to be an Asiatic sub-genus, and that C. Brahma,

of Gory, belongs to it, forming, perhaps, another section.

ON THE CETONIIDEZ OF SOUTH AFRICA. i9

Sub-genus 5. Crypropus, M‘L.

32. When my description of a New Holland insect of considerable size, which I called

Cryptodus parodoxus, was published in 1819, I had never seen any species of the genus

Cryptodinus, and I was even ignorant that any insect belonging to the family Cetoniide

could possess corneous mandibles and maxille like the insects I shall hereafter describe

under the names of Macroma and Oplostomus, or could have a semicircular clypeus like

that of Cymophorus. The consequence was, that when a beetle was presented to me with

antenne: of nine joints, like those of Mechidius, which it also resembled in general form, and

when, in addition, it offered to my notice sharp arched horny mandibles, and maxille termi-

nated by sharp horny hooks, I assigned it to the family of Trogide, merely stating my doubts

and difficulties, while I gave it the name of Cryptodus paradoxus. Since that period, I have

become acquainted with many Cryptodini, and have found their habits to be analogous

to those of the Zrogide, which they represent in the family of Cetoniide. It is now long

since that, by reflecting on the concealed labrum of Cryptodus, the dilated triangular scape

of its antenne, the horny mandibles and maxille, similar in form to those of Macroma and

Oplostomus, the large mentum closing up the mouth, and concealing the palpi, with its naked

podex so different from that of the Zrogide, its depressed body, and peculiar structure, [

became convinced that I ought to have assigned this most curious insect to the family of

Cetoniide, and that it ought to have been placed in the immediate vicinity of Cremastocheilus.

Still, however, the insect well merits the title of paradoxus, since it is as unlike Cetonia aurata,

or any of the usual types of the family, as well may be; and besides, is the only known insect

among the Cetoniide that has not ten joints to the antenne. In short, this species serves to

demonstrate the difficulty of discovering rigid characters for any family ; and ere we have

finished with the Cetoniide, we shall find almost every character of this groupe to give way

except, perhaps, the concealed labrum. Yet no groupe of Coleoptera seems better marked

out by nature.

33. Without having any thing very remarkable in its external facies, Cryptodus, perhaps, is

the most singular sub-genus of all the Petalocera in an entomological point of view. It

differs from the generality of its family, almost as much as Hexodon does from the Rutelide.

Its flat depressed body, its broad mentum, and black colour, seem all to indicate that its place

in the genus Cryptodinus is exactly analogous to that which the sub-genus Platygenia holds

in the genus Trichinus. Iam well pleased now to have an opportunity of correcting my

original mistake as to the affinities of Cryptodus, since the correction will tend to enlarge the

characters I have given to the Cetoniide, and to restrict those of the family of Trogide. It

is satisfactory also to find after so many years, that this is almost the only error of conse-

quence in my collocation of the new forms described in the first part of the Hore Entomologice,

and that even this error was suspected at the time of its publication. I possess two species

of the genus Cryptodus, both from New Holland.

34, But we shall now return to the sub-genus Grenuchus, which alone of all the sub-genera

of Cryptodinus indicates a tendency to have the epimeron prominently intervening between the

thorax and shoulders of the elytra, and so we proceed to the next genus Macrominus.

Genus I11. MACROMINUS, Mihi.

35. This groupe differs from the last genus Cryptodinus, in having the epimeron distinct

20 ON THE CETONIIDA OF SOUTH AFRICA.

between the angles of the prothorax and elytra; it also differs in having the scape of the

antennee reduced to a more ordinary size, and in having the maxille often furnished with

hair, among which occur those horny teeth which always arm the terminal process of these

organs of the mouth, and thus form the distinguishing character of the genus, which how-

ever approaches near to the genus Cetoninus, by the affinity of transultation.

Nor. The plantule and pseudonychia are distinct in all these sub-genera except in Macroma, where

they are evanescent. I have given Gory the credit of the sub-genus Diplognatha, although he has in-

cluded insects in it which do not belong to the groupe.

Sub-genus 1. Optostomus, M‘L.

36. This sub-genus retains many of the characteristics of Cryptodinus, particularly in the

antenne, mentum, maxille, &c. as will be seen from the following description, viz.

Antenne of ten joints, with the scape sub-triangular depressed above, and as long as

the next six joints taken together, or as the ovate clava, which consists of three

joints.

Mandibles corneous, with a blunted point, having the membranaceous part small.

Mazxille corneous, prismatic, hirsute at the back, with the terminal process composed of a

long sharp hooked tooth, and the imner process armed at the point with a smaller

sharp tooth.

Mazillary palpi shorter than maxille, with the last jot twice as long as the rest taken

together, and having the first joints evanescent.

Labial palpi remarkably short, with the two first jomts evanescent.

Mentum sub-quadrate, forming a transverse triangular prism; in front it is truncated with the

sides rounded off; in the middle is the transverse ridge, forming a prominent obtuse

angle; at the sides there is a tooth, that projecting forms a sinus for the labial palpus,

which appears at first sight to have only one joint.

Head small, with quadrate clypeus. Prothorax trapezoidal, emarginate behind. Scu-

tellum large, triangular. pimeron distinct between prothorax and elytra. Elytra

with shoulders slightly lobate. Body depressed like Cetonia morio. Mesosternum

narrow, blunt, not advanced between the legs. eet short, with the anterior tibie

externally bidentate.

37. Olivier has described an insect from Senegal, under the name of Cetonia fuliginea, which

MM. Gory and Percheron, have, with some reason, assigned to their genus Cremastocheilus.

It may however be easily separated from that groupe by the circumstance of the epimeron

being prominently distinct between the prothorax and the shoulders of the elytra. I believe the

following insect brought from the Cape by Dr. Smith, to be identical with the Senegal species.

At least I can observe no very important difference between the description of Olivier’s insect

ON THE CETONIID OF SOUTH AFRICA. 21

and that of the present Cape species. The whole insect is black, except the nine last joints

of the antenne, which are fulvous. M. Gory only states that the three joints of the clava

are fulyous in the Senegal species; but, perhaps, this is a mere omission, and therefore I

shall register our Cape insect as follows.

Sr. 9. (Macrominus) Oplostomus fuligineus, Oliv.

Cremastocheilus fuligineus, G. P. p. 110. tab. 15. fig. 1.

38. We have to pass on now to the following sub-genus.

Sub-genus 2. ANoptocHEitus, M‘L.

Antenne of ten joints, the first obconic, and the second globose.

Mandibles having their corneous external process very little longer than the membranaceous

part.

Mazille horny, prismatic, and long, having the terminal process not distinct from the mner.

Mentum narrow convex, with the anterior edge semicircular.

Head small, subquadrate. Body convex and thick. Epimeron very visible between

thorax and elytra. Scutellum large, triangular. Mesosternum blunt, and not produced.

Feet short and strong, with the fore tibiz tridentate, and the posterior femora some-

times incrassated, as are also the posterior tibie, which are always externally sub-

bidentate.

This sub-genus has a prismatic maxilla, something like that of Genuchus; only terminating

in three equal horny teeth. Genuchus has only two teeth to its maxille. But both sub-

genera agree with Oplostomus in the outer side of the terminal process of their maxille, having

no brush of hair.

39. I do not know whether I am altogether accurate in placing the following Cape insects

with indistinct pseudonychia in this sub-genus, because I have not dissected them; but they

appear to agree in several respects, and possibly only differ as belonging to another section of

the sub-genus. In external appearance they are all three very much alike.

first joint of the posterior tarsi.

Cetonia tomentosa, G. P. p. 226. tab. 51. fig. 5?

Nore. The description and figure of Gory and Percheron answer so well to my insect, that I am un-

willing to believe it to be a distinct species, although they say that the Cetonia tomentosa of Klug is a

Mexican insect. By the way, with their usual accuracy, these gentlemen have another “ Cetonia tomen-

tos” from Mexico, which is probably a true Cetonia. I shall merely now repeat that as the clypeus of

22 ON THE CETONIIDZ OF SOUTH AFRICA.

Anoplocheilus tomentosus is sub-emarginate, the species appears to belong to a different section of the sub-

genus when compared with Anoplochetlus spinitarsis, If on dissection of the mouth they should agree

with the genus Cetonia, these two species A. setosus and A. tomentosus will evidently enter into the

last Trichoid section of the sub-genus Cetonia.

Sub-genus 3. Diptocnatua, G. P.

40. This sub-genus of M. Gory agrees with Anoplocheilus in having the end of the maxilla

armed with sharp teeth. Indeed this is the character of the whole genus Macrominus; but

the terminal process is in Diplognatha distinct from the base of the maxilla, and is furnished

on the outside with a brush, as in the genera Trichinus, Cetoninus, and Gymnetinus. The

mentum also is broad, truncated, scarcely emarginate in front, and having the corners rounded

off. But for the rest I refer to MM. Gory and Percheron’s description of this groupe, which

appears to admit of the following sections. As all the sections, however, are not yet known,

it is difficult to place them accurately; and I give the following arrangement only provi-

sionally :—

SECTIONS OF DIPLOGNATHA.

aaa Jf Terminal process of maxille ending in two sharp teeth.

L Inhabit Africa.

41. The first of these sections is numerous in species. The type of it may be considered to

be Cetonia crucigera of Olivier. Cremastocheilus maculatus of Gory appears to form another

section. The general colour of the first section is black, often variegated with white spots.

42. To the second of these sections appears to belong the common Cape insect, Scarabeus

carnifex of Linnzus.

Lone. Corp. 15 lines.

Notre. MM. Gory and Percheron seem to have confounded this last species with the true Cetonia

Gagates of Olivier, which is a Senegal insect, and smaller, having the labial palpi stretching beyond the

mentum, the sides of the elytra parallel, the anterior tibiee tridentate, and the mesosternum rather obtuse.

I have found Diplognatha Gagates common at Porto Praya in the Cape de Verds ; but I cannot say that it

is a flower-frequenting insect, as I never met with it except in the Cocoa-nut groves below the town, and

ON THE CETONIIDZ OF SOUTH AFRICA. 23

always on the foliage of the underwood which grows beneath the Palms. The whole section of Diplog-

nathe Gagatesie is remarkable for having a thorax lobed behind like that of the genus Gymmnetinus.

Sub-genus 4. Gratuocsra, Kirby.

44, This is the genus Gnathocera of Kirby, as published in the Linnean Transactions ; but

it is not the genus G'nathocera of Gory. By the last entomologist our present groupe is called

Amphistoros, and although he has adopted the very same type for it as Mr. Kirby, namely,

the Cetonia elata of Fabricius, he has given Kirby’s name Gnathocera to another groupe !

This confusion has arisen from indolence, or rather from the usual unwillingness of the French

to consult original authorities. Mr. Kirby, not aware that the type of his new genus had

been described by Fabricius, called it Gnathocera vitticollis. But instead of reading Mr.

Kirby’s well-known papers, M. Gory appears to have merely consulted the catalogue of

M. Dejean, a work too full of this kind of error. The name Amphistoros, therefore, can never

be applied, unless perhaps to some hereafter-to-be-discovered section of this sub-genus; and

the groupe called “ Gnathocera” by Gory requires another name. [ shall, however, save

naturalists the trouble of inventing a new one, by adopting for Gory’s groupe the name

of Coruphes or Coryphe, which, according to what is stated in his introduction, he originally

intended to give to it.

45. The sub-genus Gnathocera is tolerably well marked out by Kirby, but by M. Gory the

parts of the mouth are badly described, and erroneously figured. The outer and inner lobe of

the maxilla are both furnished with about three or four small teeth in each. This curious

form of maxille, the dentated clypeus, the advanced mesosternum, and emarginate mentum,

all serve to separate G'nathocera from Diplognatha. As yet we only know one section of it,

which is from Intratropical Africa.

Sub-genus 5. Macroma, G. P. -

46. This is one of the most singular sub-genera of the Cetoniide yet known, so far as the

organs of the mouth are concerned ; but it shews that M. Gory neither understood the true

character of the family, nor had fully investigated the structure of the sub-genera, when he

distinguished the Cetoniide from the rest of Petalocera, by their having the mandibles

“rudimentary or even absent.” Here is a sub-genus, called “ Macroma” by Gory, which has

mandibles and maxille as strong, hard, and corneous as any melolonthidous insect. Still

they are but modifications of the usual manducatory organs of the Cetoniide. The maxille

and mentum are more accurately figured than usual by Gory; of the mandibles he says

nothing. These are shaped like those of Mechidius, only sharper; the membranaceous

subquadrate part being evanescent. The maxille have two strong teeth at the apex of the

inner lobe, and one strong sharp curved one holding the place of the terminal process. I

understand this maxilla to be that of Gnathocera, only modified in as far as that the several

teeth in each lobe of the latter sub-genus are here confluent, so as to form a maxilla which has

nothing resembling it among Petalocerous Coleoptera, unless it be that of Oplostomus,

Cryptodus, or Cremastocheilus. ‘There is no pencil of hair on the outside of the terminal process.

If Macroma javanica and M. bicolor of Gory belong to this sub-genus, as I believe they do,

then they will probably form distinct sections of it. The type of the sub-genera has hitherto been

brought from Senegal; but Dr. Smith having gone north within the tropics, has brought it also

from the extreme point of his journey. This is the more curious, as he was on the east coast, so

24 ON THE CETONIID OF SOUTH AFRICA.

that it appears to be an insect having a very wide range. But the truth is, that Dr. Smith has

brought many species which I find to be identical with those of Senegal, and some with those

even of Upper Egypt.

Sp. 16. (Macrominus) Macroma scutellata, Fad.

Macroma scutellaris, G. P. p. 148. tab, 23. fig. 4.

47. M. Gory assigns the name Macroma to Mr. Kirby. Iam not aware of the work in

which Mr. Kirby has published it, but, at all events, this would not seem to have been the

name given byhim to Macroma scutellata. If Mr. Hope be correct, the true Macroma of Mr. Kirby

is probably one of the sections of the sub-genus Schizorhina. Gory, in his “errata,” says, with a

ludicrous desire to be profoundly accurate, “Aux genres Macroma et Schyzorhina de Kirby il y

eu par mégarde une transposition de noms; ainsi nos Macroma sont les Schyzorhina de Kirby, et

les Schyzorhina de Kirby sont nos Macromes!” Now, this is rather unfortunately asserted,

since, as S. 4-punctata is the first species of the genus “ Schyzorhina” mentioned by Gory,

and S. atropunctata is Mr. Kirby’s type of his genus Schizorhina, (called Schyzorhina in

Dejean’s catalogue,) and since these two species are so close as to be scarcely more than

varieties, why it is very clear that the Macroma scutellaris of Gory is not a Schizorhina of

Karby, but that the Schizorhina of Kirby is the very same groupe as that mis-called

Schyzorhina by M. Dejean and his copier Gory. Whether Mr. Kirby be really acquainted

with the singular sub-genus Macroma, I know not; for Gory, when he attributes the institu-

tion of his “genus Macroma’’ to our venerable countryman, evidently follows his usual, sole,

and sovereign authority, Dejean’s Catalogue. I shall only say, that whoever first named this

sub-genera, pointed out a most natural and curious groupe.

48. We shall now return to the sub-genus Diplognatha, which has a quadrate clypeus and

a thorax that commences to be lobate behind. It has also the terminal process of the maxilla

clothed behind with a brush of hair, and armed with curved corneous teeth at the apex, while

one of its sections has an irregular clypeus. But all these characters belong to Philistina,

which is a sub-genus of my Gymetinus.

Genus 1V. GYMNETINUS, K.

This is a groupe which is distinguished by the middle of the thorax being produced behind

into a lobe that conceals the scutellum in a greater or less degree, sometimes even entirely.

It is a genus which has the mentum always emarginate, and, like Macrominus, is entirely

extra~European. None of the species, however, are found on the African Continent.* ‘This

genus answers to the family Gymnetide of Kirby, and Gymnetides of MM. Gory and

Percheron ; but it is not easy to discover the rules which these gentlemen have followed in

distinguishing families from genera, or whether mdeed they have had any rule at all, as they

rarely deign to characterize their groupes. All the sub-genera which I shall now proceed to

detail have the pseudonychia very distinct, except Agestrata and Lomaptera, where they

appear in some degree to be evanescent. I need scarcely say that I have not ascertained the

proper character by which to separate the normal from the aberrant groupe.

* T see no good reason for believing that the Cetonia strigosa of Fabricius is a native of the Cape of Good Hope.

49. In the Zoologisches Magazin, Band 2, Stiick 1, published in 1823, M. Wiedemann

described a Javanese insect under the name of Goliathus rhinophyllus. As such the insect

appears in Dejean’s Catalogue ; and I confess that when I first saw the species many years ago

in the collection of M. Bosc, at Paris, I also considered it to belong to the sub-genus

Goliathus. In the monograph of MM. Gory and Percheron, however, the insect is called

“ Macronata rhynophylia,” and Wiedemann is erroneously cited as the authority for this

double barbarism. These French naturalists are so far right in assigning our insect to the

sub-genus Macronota of Wiedemann, that it certainly comes much nearer to this groupe than to

Goliathus. M. Latreille seems, nevertheless, to have been the first who observed that it was not

a Goliathus. From this sub-genus it differs in the long corneous part of the mandibles, in the

maxille being armed with corneous teeth, in the mentum being very slightly emarginate, and

in various other particulars, so important as to prove to us that the obvious relation which this

Javanese insect bears to Goliathus is nothing more than one of analogy ; and on account of

this analogy I have assigned the species to the

Sub-genus 1. Puitistina, M‘L.

Antenne of ten joints, the scape being long and obconical, the second joint globose, larger

than the remainder, the three joints excepted that compose the long pear-shaped clava.

Labrum membranaceous, emarginate.

branaceous part.

Mazxille short, prismatic, and terminating in three, if not more, sharp corneous teeth, which

probable that the above description is rather the character of a section than that of the sub-genus to which

this section belongs. I believe that this sub-genus contains many forms, all resembling Goliathus. Mr.

Hope, for instance, indicates, as a section, a genus called Juwmnos which may possibly come here. But I

know it not.

Sub-genus 2. AcustRata, Eschscholtz.

50. This groupe agrees with Philistina, inasmuch as the maxilla is armed with a corneous

tooth, which is covered with a long pencil of hairs, while the clypeus is quadrate and formed

like that of the female of the foregoing sub-genus. But here the mentum is deeply emargi-

nate, the mesosternum is advanced, the scutellum is minute, and the sexes differ in only one of

them having the anterior tibiz externally tridentate. The type is the common Agestrata

chinensis, and there is no other section as yet known, although Mr. Hope says that he is

acquainted with ten species.

Sub-genus 3. Lomaprara, G. P.

51. This sub-genus differs from Agestrata in having the clypeus and mentum deeply cleft,

while the maxilla terminates im a mere pencil of hairs, the mesosternum is produced into a

spine, and the scutellum disappears under the enormous sharp-pointed lobe of the thorax. In

neither this nor the preceding sub-genus are the pseudonychia very distinct. Lomaptera is a

groupe composed of beautiful insects, which appear to haye their metropolis in Timor and New

Guinea. A good type is the splendid Lomaptera bivittata of MM. Quoy and Gaimard. But

the truth is, that only one of the sections is known.

Sub-genus 4. Gymyzris, M‘L.

52. This sub-genus has the clypeus entire, and the quadrate mentum simply emarginate at

the front. Here, moreover, the scutellum altogether disappears under the great lobe of the

thorax. Only two American sections have as yet been characterised, viz. 1. SuB-coRNUTz,

of which the type is Gymmnetis nitida (Hore Entomologice, p. 153,) which may be charac-

terized by their sub-cornute clypeus, and very minute scutellum ; and 2. Marmorina, K., of

which the type is Gymnetis marmorea, (Zool. Journal, vol. 3. p. 153,) and which may be

distinguished by their simple clypeus, and their having no visible scutellum. But there are

other sections known, one at least of which is Asiatic.

Sub-genus 5. Macronota, Wiedemann.

53. MM. Gory and Percheron exhibit their acquaintance with the signification of this name

by always terming it “ MWacronata.” The sub-genus comes very close to Philstina. As in it,

the elytra are here much wider than the thorax, which is not deeply lobed, and the scutellum

is conspicuous, while the mesosternum is not far advanced. But, on the other hand, the

deeply emarginate mentum, and the maxilla without corneous teeth, serve to separate it from

Philistina, and to join it to G'ymnetis. Macronota is an extensive groupe, offering sections and

sub-sections. I am not aware, however, that any have been hitherto separated except the

genus Dorysceles of Dejean, which is merely a section of the sub-genus Macronota, and of which

the type is Macronota calcarata of Klug, which is a native of Madagascar. This section is to

be known from the rest of the sub-genus Wacronota by the clypeus bemg narrower at the

apex, and by the mentum not being so deeply emarginate. The male of the only known

with it, of which the inner one is curved, falciform, exceedingly acute, and nearly as long as the

whole tarsus.

54. As none of the above five sub-genera are found at the Cape—nor indeed in Africa—I

have no occasion to say more of them, than that all, except Philistina and Agestrata, have the

external process of the maxille membranaceous. Yet I have never seen the American species

of Gymnetis on flowers, but invariably have found them by beating the leaves of trees, out of

which they fall on the ground, as if dead, not moving a limb. I suspect that the other

sub-genera, from their superior brilliancy of colour, are more fond of flowers than Gymunetis.

55. From Lomaptera, the metropolis of which is New Guinea, and which has its clypeus

deeply bifid, we pass possibly by one of the sections unknown, to the New Holland groupe

Schizorhina, which also has the clypeus forked. But Schizorhina is a sub-genus of the

Genus V. CETONINUS, Mihi.

The thorax of Cetoninus is never lobed behind, but rather emarginate. The mandibles are

membranaceous, and the maxille scarcely ever armed with corneous teeth, but merely furnished

with a pencil of hairs. The females always have the anterior tibie externally dentated ; and

both sexes almost always have the epimeron prominent between the angles of thorax and elytra.

The species of this genus are found in all quarters of the globe, but particularly in Africa. In

America they are comparatively rare, the sub-genus Gymnetis of the preceding genus

Gymnetinus assuming their place there in the economy of nature. The following are the

Sub-qenera,

56. They who study natural history philosophically, must have observed with Fries how

strongly marked are those analogies which exist between the corresponding points of the two

parallel divisions of a normal groupe. Here the genera Cetoninus and Gymnetinus form the

normal groupe of the family of Cetoniide, and the analogies between their sub-genera are as

follow :—

1 LoMAPTERA. Clypeus cleft in both sexes. 1 ScHIzORHINA.

2 AGESTRATA. Males with unarmed anterior tibie. 2 CoryYPHE.

3 PHILISTINA. Males with a horned clypeus. 3 GoLIATHUS.

4 Macronora. Thorax narrower than elytra; feet long. 4 IscHNOSTOMA.

5 GYMNETIS, Body depressed ; feet short. 5 CETONIA.

Again the Sub-genera of Cetoninus represents the five Génera of the Family, thus :

ScuizorHiInA by its cleft clypeus represents Lomaptera of GYMNETINUS.

CorYPHE is a part of and the very perfection of CETONINUS.

GoLiaATHUS by the epimeron of the Ince represents TRICHINUS.

Iscunostoma by the convex mentum of the Celocephale CryPToDINUS.

sent it in the genus. In fact, no insects of this genus have such a peculiarly cetonine aspect, if I may use

the expression, as the brilliant species of Coryphe. But I proceed to the discussion of the sub-genera.

Sub-genus 1. Scuizoruina, Kirby.

57. This is remarkably like Zomaptera, for the clypeus in both sexes is more or less cleft.

The mesosternum, in like manner, is often prominent and acute. The females have the anterior

tibie externally tridentate, but the males have them without teeth. The maxille are long, with

the terminal lobe also long and villose. The mentum is more or less emarginate ; and the groupe

is almost peculiar to New Holland and the adjacent islands. The species called Schizorhina

Brownii by Kirby is evidently the nearest to Lomaptera, as it presents vestiges of the lobate

thorax. There are five sections known, for which the following names may serve in want of

better :—

Nore. As none of the above sections occur in Africa, I shall say little of them, except that Gory

erroneously confounds the Cetonia carinata of Donovan with the C. Phillipsti of Schreibers. Being

in possession of the identical specimens described by the latter naturalist in the Linnean Transactions, I

have the means of judging; but I must confess that the two species come very near to each other.

The last section, which I have called Insutares because they are in general natives of Mada-

gascar or of the islands adjacent to New Holland, has a narrow advanced mesosternum —

elytra with parallel sides, and which are spinose at apex. The inner process of the maxilla

in these insects has no tooth, and their mentum is deeply emarginate. All these circum-

stances, and others, such as their peculiar colours, and the females having the anterior tibice

externally tridentate, show us how we may pass to the next sub-genus, which however will be

found to have the clypeus never cloven.

Sub-genus 2. CorypuE, G. P.

58. This, as I have already stated, is called the genus G'nathocera of Kirby, in the monograph

of Gory and Percheron. Now, as I have shown this to be an error borrowed from Dejean’s

Catalogue, and as the present groupe is an excellent one, which had previously been named

“ Coruphes’ by M. Gory, on account, as he says, of its carinated vertex, I think no one will

object to his first nomenclature, unless perhaps they may think it necessary to correct his

spellmg, which certainly ought to be Coryphe or Coryphea. I prefer the former word, as it

appears to be what M. Gory was aiming at; and, besides, means a lady’s ornament, for which

purpose, in fact, some of the brilliant species of this sub-genus serve in the Phillippine islands.*

It is true that Dr. Leach gave this name “ Corypha” to a groupe of Staphylinide ; but it has

never been adopted, so far as I know; and Gory has certainly the right to name a groupe of

which he first pointed out very nearly the true limits. It is distinguished from Schizorhina by

the porrected mesosternum diverging from the prothorax, by its often carinated vertex, and

clypeus always entire in front. From the sub-genus Goliathus, to which it is exceedingly

close, this sub-genus may be known by the maxille having the terminal process shorter and in

a line with the base, and by the mentum being more truncated, but, above all, by the horny

part of the mandibles being much longer than the square membranaceous part. The males

scarcely ever have any teeth on the external side of their anterior tibiee, and when they possess

such teeth it is merely because they belong to aberrant species.

I have named one of these sections after a prominent species. Mr. Kirby indicated another

under the name of Chlorocala, as did Mr. Hope another under the term Rhomborhina. The

second section in the above list is what MM. Gory and Percheron term their genus

“ Dicheros.” And as for the first, M. Dupont has some right to name it, since one of the

imsects he calls “ Varycius” appears to belong to it.

59. With respect, then, to the section Narycrm of Dupont, I would observe, that it is

remarkable for its brilliant green colouring, which is sometimes rendered still more vivid by

spots of some different hue. The groupe is entirely Indian, and the Coryphe MacLeaii (the

Cetonia Mac Leai of Kirby) seems to be its best type. Here I may remark, that the Gnatho-

cera MacLeati of Gory is not the Cetonia MacLeaii of Kirby. In the latter species the black

discal spot of the thorax does not touch its hinder margin, and besides the clypeus of the

male has not two parallel horns proceeding from its sides, but only one short vertical horn,

something like that of the well-known insect Coryphe flavomaculata, Fab. The Gnathocera

MacLeaii of Gory ought therefore to retain the trivial name it originally received from its disco-

verer Eschscholtz, and be henceforth called Coryphe pretiosa. But this species, together with

the insect called Narycius olivaceus by Dupont, and the beautiful Cetonia guttata of Olivier,

* See Linn. Trans. vol. 12. p. 409.

30 ON THE CETONIIDZ OF SOUTH AFRICA.

appear to be aberrant in the section, and to connect it with the following one called Diceros.

The following species indeed may perhaps represent so many sub-sections :—

{1 Cetonia elegans, Fab. Colour green. & Clypeus with no horn.

(2 Cetonia MacLeaii, K. Colour green with black spots. ¢ Clypeus with a short vertical horn.

[ 3 Cetonia pretiosa, Esch. Colour green with black spots. ¢ Clypeus with two lateral horns.

< 4 Cetonia guttata, Oliv. Colour green and red with white spots. ¢ Clypeus with two lateral horns.

5 Narycius olivaceus, Dup. Colour green. ¢ Clypeus with two lateral horns.

60. With respect to the section DiceRos, it is true that MM. Gory and Percheron have made

a genus of it; but except a slight difference in the form of the thorax, and the colour, we find

little to distinguish the groupe from the section Waricia, which I have founded on the badly

characterized groupe which has been called Narycius by Dupont. The organs of the mouth

are the same in both. However, there are as yet only two species described of the section

Diceros; namely, the Cetonia bicornis of Latreille, a Timor insect, which is figured in the

fourth volume of the first edition of Cuvier’s Regne Animal, and the Dicheros decorus of Gory,

which is a Javanese insect. The Cetonia bicornis of Latreille is called “ bicornuta’’ by Gory,

and, what is singular enough, is erroneously assigned by Mr. Kirby to his own genus Gnathocera.

61. The type of the third section RaomBorutna is the G'nathocera Hardwichii of Gory, a

Nepaul insect, which is horned, and comes very near to the Goliathus 4-maculatus of Africa.

The difference between them consists in both sexes of Coryphe Hardwichit having the clypeus

alike, and in the female having the anterior tibie externally bidentate. Although I am not

acquainted with the insect, I suspect that the Goliathus opalinus of Gory, which Mr. Hope

is said to have made the type of his groupe Zrigonophora, will eventually be found to form

a sub-section of Rhomborhine, where the female has a simple clypeus. And I have reason

to suspect, moreover, that the insect called “Jumnos Ruckert” in Mr. Hope’s Coleopterist’s

Manual, forms still another sub-section of the Rhomborhine, which comes yet nearer to the

sub-genus Goliathus than either of the former sub-sections, and osculates with it. All the

species of this section are Asiatic.

62. The fourth section, ScuiprELiia, is African, and may be easily known by the sharp

prominent sternum, and by the anterior tibie of the males being without teeth, while those of

the females have externally three. This groupe will admit of sub-sections, of which the

following insects appear to be types.

63. Dr. Smith has brought home the type of the first of the foregoing sub-sections, viz. :—

Sp. 17. (Cetoninus) Coryphe flavomaculata, Lad.

Gnathocera flavomaculata, G. P. p. 189. tab. 21. fig. 5.

Norr. MM. Gory and Percheron have only described the female. ‘The male has a short horn on the

vertex, and the apex of its clypeus is recurved and emarginate. The male has also its anterior tibice

without teeth. By the way, the trivial name of this common species ought to be “ demaculata,” for no

less an entomologist than Degeer originally described and figured it under this name. If this change be

adopted, the Oetonia bimacula, Wiedem., which if it be the same as the Gnathocera bimaculata of Gory,

appears to belong to some sub-section of Diceros, may then be called Coryphe Wiedemanni.

ON THE CETONIIDE OF SOUTH AFRICA. 31

64. Of the second sub-section of Schiippellie, Dr. Smith has also brought home one

species, which M. Gory confounded with the Cetonia Tenia of Palisot de Beauvois. I

happen to possess both species, and find them to be quite distinct. In the true Coryphe Tenia

the margin of the thorax is not yellow, while the body is wider than that of the new Cape

species, and the colour more viridi-zeneous. I shall honour my new species with the name of

the distinguished philosopher to whom Dr. Smith’s expedition was so much indebted. It will

also commemorate his uncle, who was a meritorious entomologist, particularly attached to the

study of Coleoptera. I may here observe, that M. Gory has only described the male.

@ Cetonia propinqua, G. P. p. 265. tab. 51. fig. 3.

Norr. Here MM. Gory and Percheron appear to have described the male and female as different

genera. The female has a simple quadrate clypeus, and the anterior tibie tridentate. According to

M. Gory, she comes from Mexico. However this may be, Dr. Smith has brought her also from the

Cape of Good Hope, from whence M. Verreaux has also brought me the male.

66. The fourth sub-section, as yet, has only been found in intratropical Africa. Its type is

Coryphe suturalis, Fab., which resembles C. umbonata exceedingly in colour and markings ;

but the body is narrower, and this insect leads us to the Coryphe bimacula, Wiedem., by the

affinity of transultation.

67. I now proceed with the sections of Coryphe, as the fifth, which Mr. Kirby has called

CuiLorocaL#, has not yet been particularly noticed. The Coryphe Africana, Fab., is a very

good type of this groupe, which is entirely African and intratropical. It comes very near to

the Asiatic section “ WVaricie,” and like it, is remarkable for its brilliant green colouring, only

here this colouring is pure and without spots. But we must now return to the aberrant section

“ Rhomborhine,” as it leads us to what may be deemed the principes Coleopterorum.

Sub-genus 3. GouiatHus, Lamarck.

As this is perhaps the most beautiful groupe of Coleoptera known, and as one of the sections

consists of the largest as well as rarest insects that can grace our cabinets, I shall give a briet

view of all the species of the sub-genus which are known to me. The males have the clypeus

always horned, but the thorax never; which, by the way, will distinguish Goliathus from Philis-

tina. The maxilla has rarely any corneous teeth, and its terminal lobe, crowned with a pencil

of hair, is always bent inwards at right angles toits back. The corneous lobe of the mandible

is very short, and rarely longer than the square membranaceous part. The mentum is deeply

emarginate or bilobed.* The males have the anterior feet elongated, while the females have

the anterior tibie always externally tridentate. The three species called by MM. Gory and

Percheron Goliathus heros, Goliathus Melly, and Goliathus opalinus, appear all to belong to

the last sub-genus Coryphe, although they undoubtedly approach very closely to that section

* Professor Klug describes it as trilobed in the female of his Goliathus regius, but this is probably a mistake.

32 ON THE CETONIIDEA OF SOUTH AFRICA.

of Goliathus, which I shall call Smithii, after my friend Dr. Smith. There is another species

mentioned by M. Schonnherr, and described in his appendix under the name of Cetonia geotru-

pina, which I am clearly of opinion belongs to the sub-genus Ischnostoma, and to the section

of it called by me Celocephale.

Tropical Asia.

Section 1. SmrrHit.

68. This section inhabits intratropical Africa. It may be easily known by having the elytra

wider at the base, by having the body very depressed, by the thorax being nearly truncated

behind, or, at least, being only slightly emarginate, to receive the scutellum. In short, this

groupe comes very close to the general form and colouring of the sub-genus Coryphe, and

the female indeed, not having a horned clypeus, can with difficulty be distinguished from it.

The males have almost always the anterior tibia denticulated on the inside. The Goliathi

Smithit have a quadrate head, and admit of the following sub-sections, which I shall not name,

as my object is merely to shew their structure and affinities :—

Nore. An unique specimen of this rare and valuable insect was for many years the chief ornament of

the Entomological Cabinet bequeathed by the late Sir Joseph Banks to the Linnean Society. It was the

male described by Fabricius and figured by Olivier. This specimen however appears to have been stélen

since the insects of the Banksian Cabinet were arranged in 1826 by the late Messrs. Bennett and

Haworth. MM. Gory and Percheron state that their figure of the male is from a specimen in their pos-

session. The above description of the species is compiled from the works of Fabricius, Olivier, and Gory.

There appears however to be more than one specimen known, for Mr. Melly of Liverpool assures me that

an insect of this species was lately exhibited for sale at Glasgow, and purchased by Sir William Hooker

the Professor of Botany. Mr. Hope, however, is of opinion that Sir W. Hooker's species is different.

Perhaps it is the male of G. torquatus. The above two normal sub-sections differ from the following

aberrant sub-sections in not having the vitreous lustre of these last, but on the contrary, having a

mentioned in place of G'. Inca.—I have lately seen another species of the same sub-section larger than

this, in the possession of Mr. Strachan who brought it from Sierra Leone. It is quite new, and differs

from Goliathus micans in a broader form and in the clypeus being entirely black. The horn of the male is

also quite different, approaching more closely to that of a Ooryphe. I believe that gentleman intends to

describe it.

The male is in my cabinet. It is a species that comes very close to G. micans, and belongs

Nore. Messrs. Gory and Percheron have figured the female from Mr. Hope's collection, taking it for a

Coryphe (or as they erroneously call it, Gnathocera) to which sub-genus all the females of the Smithian

section of Goliathi, so nearly approach. Olivier, Fabricius, and Schénnherr, seem also to have known

only the female. On the other hand I possess only the male, and as my specimen has lost the last joint

of all its tarsi, I cannot say whether the last joint of the anterior tarsus has a brush on the inside above

the ungues or not. The species comes close on the confines of the following sub-section, as may be seen

by the structure of the anterior tibize of the male, which are not multidentate on the inside, according to

the rule of. the Goliathi Smithii in general. My friend Mr. Hope says that this species is identical with

the Goliathus Daphnis of M. Buquet; but the last named entomologist is nevertheless right in consider-

ing the two to be distinct species, since the horns of the clypeus of the males are different as well as their

anterior tibie. Goliathus Daphnis in fact belongs to the same section as G. Smithiz, and beautifully

connects that species with the Goliathus 4-maculatus. So true it is, that while analysis is necessary for

correct synthesis, sometimes also synthesis conducts us to correct analysis.

Section 2. Héprnertt.

69. This section I only know by M. Gory’s description and figure of an insect from Mexico,

in the collection of the Count Dejean, and called by him Goliathus Hopfneri. It seems to

me to belong truly to the sub-genus Goliathus, differmg from the section of Smithii, in the

form of its head, and from the Gigantei in the form of its thorax, which is neither convex nor

lobated behind in the middle.

Norse. An unique specimen of the male is said to be in the collection of M. Dejean, and from Gory’s

description of it I have ventured to compile the preceding character. Little value however ought to be

assioned to compilations of this kind, or indeed to any description which is not founded on actual inspec-

tion. I hope, therefore, that Comte Dejean will favour us soon with a detailed description and accurate

figure.

Section 38. G1GANTEI.

70. These of all insects are the most esteemed by collectors, because they are exceedingly

rare, and at the same time most conspicuous for their size and beauty. Even the rich

collection of M. Dejean contains no specimen according to the last edition of his catalogue.

I have known fifty guineas asked for Goliathus giganteus, and a specimen now in my col-

lection is known formerly to have cost 29/. This section of the sub-genus is distinct from all

the others, and, indeed, from all the other sections of the genus Cetoninus, in having the

terminal lobe of the maxilla armed on the inside at the middle with a corneous tooth. We

thus have a character which clearly proves that these gigantic insects are aberrant, and that

they pass off by the affinity of transultation to the genus Macrominus, of which the maxilla,

internally toothed, is an essential character. The gigantic Goliathi are, at first sight, easily

distinguished from the Hopfnerit by their back being convex, and they are known from that

other section of the sub-genus which MM. Lepelletier and Serville have called Inca by the

large and conspicuous axillary pieces or epimera of the mesothorax, (See Zool. Journal, vol. v.

p- 165.) which intervene between, what is, to speak accurately, the prothorax and the

shoulders of the elytra. The Goliathi Gigantei have a strong plantula* between the ungues

of the anterior feet, and probably it exists in all‘ the feet. Unfortunately, my specimens,

although good, are not in this respect thoroughly uninjured, and thus I am also ignorant

whether the plantule be attended or not with pseudonychia. The feet are all black, but the

four posterior tibiee are along the inside fringed with a close fulvous down, while the males

have the anterior tibie thus lined only half way. The abdomen beneath is more or less

covered with the same close down. The mesosternum is advanced, broad and pointed, some-

thing like a gothic arch. It is difficult to imagine how insects so large and weighty, can

possibly live on flowers; at least the corolla, which would receive in its bosom any species of

this section, must necessarily approach in size to that of the Raffiesta. These gigantic Goliathi

may possibly live therefore on the juices that exude from the wounds of trees. One thing is

sure, namely, that the penicilliform structure of the back of the terminal process of their

maxille proves that they do live on juices of some kind. This section is confined to intra-

tropical Africa, and, as far as I am aware, only two females of it have ever as yet been brought

to Europe. There are, indeed, only five species of the section, with certainty known; and of

all these five, I believe specimens may be seen in Great Britain. I shall now take the oppor-

tunity of distinguishing them, since some peculiar circumstances attending this magnificent

groupe, give me the means of communicating information that certainly no other person

possesses ; and because I have now before me the very specimens described by Drury and

Linneus, and upon which specimens the genus Goliathus of Lamarck was originally

founded.

of the insect. The other writers who have touched on the subject, and they are not a few, have merely

known the species from the above figures. Now the original specimen, from which all the above notices

were taken, existed unique in Drury’s collection, and was the first species of the Gigantic section ever

published. I therefore consider it as the type. The specimen was found dead, and floating down the river

Drury’s Cabinet finally into that of my father, so that I am now in possession of the original specimen of

this, as well as of the still more magnificent species Goliathus giganteus, with which it has in general

been confounded, I+ has long been labelled in my cabinet as Goliathus typus ; but I understand that in

a new edition of Drury, lately published, Mr. Westwood has called it G. Druri. I need scarcely say

that MM. Gory and Percheron are mistaken when they assert that ‘Les types origmaux du genre

Goliath ne se trouvent dans aucune collection.” Drury’s figure of G. Drurii is good, except that it is

coloured much too highly.

Norte. Professor Klug of Berlin has given us, in a work published in 1835, an excellent figure and

elaborate description of the female of this new species, which was brought by Erman from the Isla de

Principe in the Bight of Benin, and is now deposited in the Royal Museum of Berlin. As far as my recol-

lection will now serve me, I believe it was a specimen of the male of this species which last year, under

the name of “ Goliathus magnus,” was exhibited to a meeting of the British Association by Mr. Frederic

Taylor of Liverpool. Goliathus regius comes exceedingly close to the next species Goliathus giganteus,

and indeed principally differs from it in being of less size, and in the markings of the thorax, which are

very distinct. ‘The elytra are wonderfully alike in both, but the pure white scutellum of G. giganteus,

and its white thorax, with six more or less abbreviated black longitudinal bands, may at once separate it

from the present species G. regius, where the scutellum is black, having only a white mark on each side,

and where the black thorax has five white longitudinal bands, of which the fusiform middle one neither

reaches to the neck on one side, nor to the scutellum on the other, but is placed exactly in the middle.

G. regius is at once to be known from G. Drurii, by the colour of the elytra. It is singular that Klug

should have accurately separated this species from Drury’s figure (vol. 3. tab. 40.) of G. giganteus, and

yet have erroneously confounded G. Drurit with G. giganteus, although these are far more distinct. We

may thus see, however, the advantage of the inspection of specimens over that of figures.

Note. According to Drury, the specimen now before me came from Sierra Leone. I have seen another

specimen of the male from that colony, of which a most wretched figure has been lately published in

London, under the title of “Cetonia Golianthus.” Drury’s figure, on the other hand, is excellent in every

respect. This entomologist suspected it to be a different species from that now called G. Drurii, by

the editor of a late edition of Drury’s work. Fabricius, Olivier, Lamarck, and Klug, have all confounded

the two foregoing species, and made them one, although the two first entomologists must have seen both

specimens, although the original describer suspected them to be distinct ; and although they will to the

eye of any modern entomologist who inspects them, appear totally different from each other. The

bifurcation of the extremity of the clypeus in the male, is of a different form from that of Goliathus

Drurvi, masmuch as the latter is curved backwards so as to resemble the Greek letter Y, whereas in

G. giganteus it resembles more the letter Y. The marking, colour, and size, are also so different, that

one is really amused to find Klug, in a late publication,* gravely laying down a theory to account for the

two unique insects of Drury’s Collection forming only one species. It is true that he never saw them;

but he read in Drury’s work that the former of these species (Goliathus Drurii,) was found dead, and

floating on the surface of the river Gaboon. Catching at this fact, in the “ Verzeichniss von Thieren und

Pflanzen,” which were collected by Adolph Erman in his voyage round the world, Klug says that the

identity of the two species being fully proved by Drury’s figures, which represent the clypeus porrected

in both beetles, and the colouring of the thorax not essentially distinct, no regard ought to be paid

by us to the very different colouring of the elytra, since the specimen figured by Drury, vol. i. t. 31.,

having been found dead in the water, may have lost its original white covering, and may thus appear to us

now of a brown colour. Such reasoning is certainly ingenious, but the colouring of the thorax is very

distinct, and, I will venture to say, that the clypeus will be found bifid and porrected even in the male

of G. regius when known; and besides, I have pointed out sufficient differences to make it certain that

Drury was right when he suspected his two unique specimens to belong to different species. I am not

much inclined to adopt Lamarck’s trivial name “giganteus,” because he applied it to both species,

G. Drurit and this; nor can I adopt Klug’s trivial name “ dmperialis,” for, in fact this is in like

manner applied by its author to an imaginary being, made up of the two foregoing species united,

which, be it observed, neither he nor Lamarck ever saw. In my specimen of G. giganteus there are two

small black spots on the hinder part of the thorax which is quite white, the two middle vitte being

abbreviated. In the other specimen which I have seen, the two middle black vittee reach to the hinder

margin of the thorax, and the two small black spots above mentioned become connected with the other

vittee on each side. Mr. Kirby, in his Introduction to Entomology, vol. iv. p. 506, alludes to some

private letter of mine to him, in which mention was made of Goliathus giganteus. I suppose, there-

fore, that at the time of writing that letter, I assigned the name which Lamarck has given both to

G. Drurii and this, to the latter species alone.

Notr. This insect, like the last, is truly from Africa, as Professor Klug perceived. The first

describers of it, however, made it to be an American species, and so dubbed it “a Cacique.” The

original specimen is said to be at Glasgow in the Hunterian Museum. I believe Mr. Hope possesses one

in spirits, and I have seen another in the National Museum at Paris. Of this last we have an excellent

figure given by M. Gory. Groliathus giganteus comes exactly between this species and G. regius, for if

we look at the marking of the thorax, we find G. giganteus to agree with G. Cacicus, and if we look at

* Reise um die Erde ausgefuhrt von Adolph Erman.

ON THE CETONIIDE OF SOUTH AFRICA. 39

the marking of the elytra, we find G. giganteus to agree with G. regius. The three species are very close

to each other; but G. Drurii is so different from them all, as almost to form another sub-section of

Gigantic Goliathe.

Note. Mr. Hope has given a figure and an excellent detailed description of this insect, of which an

unique female specimen exists in his collection. To his work I refer the reader for observations on the

section, as well as on the species. Although it remains doubtful whether this be not the female of C.

Cacicus, I am, for my part, inclined to believe Mr. Hope to be in the right when he considers it as the

female of a new species.

71. In concluding my remarks on this interesting section, I have to state that it corresponds

exactly with the limits which Professor Klug, in the Appendix to Erman’s Voyage, above

mentioned, has assigned to his genus Goliathus. Nevertheless, I consider the most typical

Goliathi, im other words, those species of Goliathus, which are most distinct from all other

species of their common genus Cetoninus, to be contained in the section Inca. Thus Inca is

aberrant when we refer to the sub-genera of Cetoninus, but on the other hand it is typical

when we are referring it to the sections of Goliathus.

Section 4. Inca, Lepell. et Serville.

72. This groupe has been most properly placed by MM. Latreille and Kirby, among the

Goliathi of Lamarck. But MM. Gory and Percheron have more lately, with a singular

taste for affinities, interposed between Inca and the other sections of Goliathus, not only the

sub-genera Platygenia and Cremastocheilus, but I know not what besides. The section

of Goliathus, called Inca by MM. Lepelletier and de Serville, has the back even more

convex than that of any of the gigantic Goliathi; but it may easily be known from all

the rest of the sub-genus by its proximity to the genus Zrichinus. Itis, in fact, the Trichinus

form of the sub-genus Goliathus, and by it the genera Cetoninus and Trichinus meet so as to

close that circle which constitutes the family of Cetoniide. The section may be characterized

by its labrum, which is almost lobate in the middle, by the subcircular convex thorax with

denticulated margin, by the convex elytra, by the internal spine of the fore femur, by the

epimeron not being prominent between the thorax and elytra, and, finally, by the bicornuted

clypeus of the male, although this last character is not to be considered by any means as

peculiar to the groupe. Here it may be noticed with respect to the whole sub-genus

Goliathus, that I consider the true clypeus of the groupe, that is, the clypeus of the female,

which is nearly of the same form and construction throughout the various sections, to be in

all essentially quadrate, having the anterior angles in general sharp, and the fore-margin

rather concave. This general form of clypeus becomes horned in two ways. In the section

of Gigantei, the trunk of the bifid horn proceeds from the middle of the emargination of

the anterior margin of the clypeus, and what are called the lateral teeth, are merely the angles

of the quadrate clypeus. In the section of Smithii, particularly in Goliathus Polyphemus,

40 ON THE CETONIIDZ OF SOUTH AFRICA.

we see that in the male these angles of the clypeus project into horns on each side of

the large central horn. In the present section, Jnca, but still more in the next section,

which Mr. Hope has marked out under the name of Dicronocephalus, the male has no horn

proceeding from the middle of the margin of the clypeus, but only those horns which arise

from the angles of the clypeus. Jnca is a section entirely confined to South America. I

shall now content myself with the enumeration of the species described by authors, and

merely observe that my collection is in want of specimens of G. bifrons, rufipennis, and the

: Section 5. Dicronocernaui, Hope.

73. This section is Asiatic, and has the sides of the elytra nearly parallel. It agrees with

the last in having the anterior tibiee furnished externally with teeth in both sexes, but it differs

in having the epimeron more or less prominent between the angles of the thorax and elytra. It

agrees with the section of Smithii in its body being depressed, but then the male has never

the anterior tibize internally multidentate. Between the anterior ungues there is a plantula in

form of spine, which is armed at the apex with diverging pseudonychia. The mesosternum is

not much produced between the legs, and sometimes is barely visible. The horns of the

head seem, as I have said before, to be productions of the lateral teeth of the clypeus in the

Gigantic section, that is, of the angles of the female clypeus, and the bifurcated horn of the

middle of their clypeus is wanting. The section admits of the following sub-sections :—

Narycius opalus, Dupont, Mag. Zool. Cl. ix. p. 128.

Nore. In Guerin’s Magazine, M. Dupont gives the figure and description of an insect from Madras,

which he places in a new genus, called by him Narycius and Naricius. He gives no distinct character

to the genus, but describes two species, of which, although they are exceedingly close to each other in

affinity, I suspect his Varycius olivaceus to belong rather to the sub-genus Coryphe. The present species (his

Narycius opalus) is curious, as being exactly intermediate between Goliathus Wallichii, G. P., and

those brilliant green Goliatht which form the beauty of the section which I have called Smithii.

Thus do we return to those Goliathi with the description of which we commenced our observations

on this rich and rare sub-genus. I must, however, before I leave the groupe, call attention to the

curious analogy that exists between Goliathus opalus and Lamprima enea, and remark how the clypeus

in one takes the form of the mandibles of the other, making Latreille fancy that they were annectent

genera. I need scarcely observe that the Goliathus opalus must not be confounded with the Goliathus

opalinus of Gory, which is a Coryphe.

74. Of true Goliathi, I consider that the above-mentioned species may be accounted as dis-

tinctly known. But we have now to return to the aberrant groupe of Goliathi Gigantei, and we

may observe a Cape insect, which M. Gory has described under the name of Diplognatha concava,

to present several points of structure held by it in common with those gigantic beetles. Like

them this insect has a three-horned clypeus, although the horns are here considerably modified,

particularly the central one, which is short and trifid. The anterior tibie are externally tri-

dentate, as in the females of the gigantic Goliathi, but here they differ, in being tridentate in

both sexes. The body is likewise convex. The thorax is rounded. The scutellum is sharp.

The epimeron is prominent between the elytra and thorax. The mesosternum is short, broad,

AQ ON THE CETONIIDA OF SOUTH AFRICA.

and subacuminate at apex. The pseudonychia are large and conspicuous. The mentum,

however, is here not deeply emarginate as in Goliathus, but, on the contrary, rather convex

in front, so that we have arrived at another sub-genus which has been called Ichnestoma, by

M. Gory; but as this gentleman has favoured us with the derivation of the word which he

intended to write, I shall correct his mistake, and call the

Sub-genus 4. Iscunostoma, G. P.

75. It is true, that taking a more extended view of natural affinities than M. Gory, I have

given greater latitude, than he has done, to the groupe here called Ischnostoma, but I do not,

on that account, conceive myself entitled to deprive that entomologist of the credit of naming

this curious sub-genus. Jschnostoma is distinguished from Goliathus, by the mentum never

being deeply emarginate, and from the sub-genus Cetonia, by the terminal lobe of the maxilla

being excessively small, and almost evanescent. This lobe, as may be expected, is largest in the

two aberrant sections which lead to Geliathus and Cetonia; but still is short, in proportion to

what we find it to be in those two sub-genera generally. The mandibles here are peculiarly

small and rudimentary, as is also the labrum, which is of a singular form in the typical

sections,—a form which indeed is different from that of the labrum in all other Cetoniide. The

mentum is never emarginate, but in general convex at the apex. All the known species are of

a black hue, that makes them little interesting except to the entomologist. From the grains

of sand which I have generally found adhering in quantity to the hair which covers the under

side of many of these insects, we may imagine that they are inhabitants of a sterile country.

Schéunherr, Latreille, and, more lately, Klug, have all placed certain insects which belong to this

sub-genus close to the genus Goliathus of Lamarck.

76. The first of these sections, here called CanocEePrHAL”, contains two known species which

MM. Gory and Percheron have erroneously assigned to their genus “ Diplognatha.” The

Cetonia geotrupina of Schonnherr is possibly a third distinct species. The maxilla here, how-

ever, has no tooth on the inner process, like Diplognatha; and if there be any thing like a

tooth on the outer process, of which I am not quite sure, it appears to be merely the acute

corner of the horny part which stretches beyond the pencil of hairs. However, I think this

must be an approach in some degree to the structure of Diplognatha; and although I am not

prepared to say with M. Gory that it belongs to that sub-genus, I certainly consider it as

evidently serving to connect the genera Macrominus and Cetoninus by what is called the

ON THE CETONIIDA OF SOUTH AFRICA. 43

affinity of transultation. I conceive Macrominus to approach Cetoninus somewhere between

the gigantic Goliathi and the ccelocephalous Ischnostome. I shall now therefore place here

the following species brought home by Dr. Smith, and which is very curious, on account of its

mentum being something like that of a Cremastocheilus.

Nore. This appears to be the insect alluded to by M. Latreille in the second edition of the Regne

Animal, as a Goliathus brought from the Cape by M. Verreaux. Diplognatha albopunctata of Gory,

which is also a Cape insect, is evidently to be placed in the same section. So also is the Cetonia

geotrupina of Bilberg, which both Schénnherr and Latreille consider to be a Gioliathus, (See Syn. Ins.

App. p. 46. 69.) Professor Klug has stated likewise his opinion that the Diplognatha albopunctata of

Gory, and the Cetonia geotrupina of Schénnherr come close to the gigantic Goliathi. They are, in

fact, only to be distinguished from them by their porrected clypeus, which, like that of Gloliathus, has a

central horn with a smaller lateral tooth on each side. Here, however, this middle horn is trifid, and the

maxilla is of a different structure.

77. The second section, X1PHOSCELIDE, has for its type an insect in my collection, which I

suspect to be from Swan River in Australia. It is remarkable for its small round thorax, long

arched posterior legs, incrassated femora, and for the apex of the posterior tibiee being produced

into a strong curved spine. The mouth agrees nearly with that of the following section.

78. The third section, ARcADE#, comes very close to the sub-genus Cetonia, so close indeed

as almost to make one suspect that it may form part of the Trichioid section of that sub-

genus; nevertheless, the smallness of the mandibles and of the terminal lobe of the maxille

induce me to place it here. It is a groupe peculiar to the Cape, and offers two sub-sections,

which completely agree in the organs of their mouth.

Both the above species have been brought from the Cape by Dr. Smith, and I shall there-

Nore. This is an insect that is almost as much a Cetonia as an Ischnostoma. I am not sure whether

Cetonia sanguinipes and C. talpina of Klug, ought to be considered as distinct species, but I think

that they are not the same.

Norz. MM. Gory and Percheron say of Ischnostoma cornuta as follows: “Cette espece quoique tres

anomale par la forme ne nous a paru susceptible de former un genre propre; les parties de la bouche la

rapprochant tout a fait des vraies Cetoines.” This is quite correct; the only difference between this

species and the true Cetonie being the cornuted thorax, and the comparative minuteness of the terminal

lobe of the maxille. It is truly osculant, between Ischnostoma and Cetonia, and comes close to the

AA ON THE CETONIID OF SOUTH AFRICA.

Cetonia hispida of Olivier. There is no affinity to the genus Syrichtus whatever, or to any of the

Dynastide. The relation between them is one of analogy.

79. The fourth section is from the Cape, and is, like the fifth, typical of Ischnostoma. Ihave

called it Hntsrocuira, because I suspect the insect described by M. Gory as “ Ischnostoma

heteroclyta” will be found to belong to it. A species of this section has been brought home by

Dr. Smith ; but, like that of the Museum of Natural History at Paris, is in sad preservation.

I must here observe, that M. Gory’s figure of Ischnostoma albomaculata is singularly incorrect,

and therefore I am led to infer that the figure of I. heteroclita is incorrect also; the more so

as M. Gory’s description of the heads of these two insects does not agree with his figures.

Sp. 24. (Cetoninus) Ischnostoma spatulipes, x. s.

Descr. Lschnostoma atronitida, capite porrecto clypeo quadrato margine reflexo apice emarginato

lobis rotundatis, corpore valde conyexo, thorace subsemicirculari punctato marginato, scutello

magno, elytris sub-rugosulis apice subtruncatis, metasterno brevissimo truncato, tibiis anticis

extus tridentatis, calcaribus posticis spatuliformibus.

Lone. 10 lines.

Note. This species may be the C. cordata of Fabricius. It has an indentation in the centre of the

thorax, being the first vestige of the deep one that exists in Ischnostoma cornuta.

80. The section Cuspiparz is, like the last, singular for its trichioid form, but differs in the

body being more depressed, and in the clypeus being of a very peculiar form, owing to its

extreme length, and the sides of it being at the base deeply emarginate. The feet are also

longer and less strong; but both sections are remarkable for a long narrow labrum, which,

however, is exceedingly minute in proportion to the size of the insect.

Sp. 25. (Cetoninus) Ischnostoma pica, 7. s.

Descr. Ischnostoma atroviolacea velutina punctata, pilis nigris operta, thoracis vittis marginalibus

acutis.

Lone. 10 lines.

Nors. This species 1s very close to the Cetonia cuspidata of Fabricius, but there are no “ puncta duo

cinerea inter autennas,” and the whole of the margin of the thorax is not cinereous. Whether Ischnostoma

pra be identical with the Melolontha albomarginata of Herbst, I know not; but certainly it is very

different from the Ischnostoma albomaculata of Gory, which is in my collection. But we now return to

the section of Arcadew, which, as I said before, comes so close to the Cetonia hispida of Olivier. By

this section we arrive at the

Sub-genus 5. Cutonta, G. P.

81. This groupe is typical of the genus Cetoninus, and contains perhaps more species than all

the rest of the family of Cetoniide put together. Cetonia may be distinguished from

Goliathus by the males not being horned, but having their clypeus of the same shape as that

of the females. The anterior tibie are also similar in the sexes, which distinguishes the sub-

genus from Schizorhina, to which it closely approaches. From Jschnostoma, Cetonia may be

separated by the sub-quadrate and emarginate mentum, and by the long penicilliform terminal

process of the maxille. In Cetonia the plantula between the ungues appears to be generally

present, only it is apt to be rubbed off by use. The pseudonychia do not seem always to be

present. This sub-genus has been left in disorder by Gory and Dejean, because it is very

difficult to be sub-divided. I offer the following rough approximation to the truth :—

82. Of the trichioid section of Cetonia, I believe no species comes from Asia or New

Holland. It represents the genus Trichinus, and therefore all the typical species of it have

the elytra, or at least the lower surface of the body, covered with hair. Fabricius placed one

species of this groupe in his genus Trichinus. The Tricnio1pE#, for the present, may be

sub-divided as follows :—

two Cape species at the entrance.

85. With respect to the section of Cetonia which I have termed CREMASTOCHEILIDEA, I may

safely say that it deserves the name ; for, in fact, these several sections of the sub-genus repre-

sent the five genera of the family; and thus the extraordinary similarity in colour and marking

that is found to exist between such insects as Cremastocheilus maculatus, G. P., and Cetonia

maculata, Fab., may be accounted for. This section of Cremastocheilidee is peculiar to Asia

and Africa, and offers various sub-sections, which for the present may be distributed as

follows :—

86. Of the three first sub-sections, we have no species brought by Dr. Smith, as they are

typically Asiatic. I shall merely therefore take the opportunity of mentioning that M.

Schénnherr is wrong in stating C. acuminata to be a native of the Cape, and that MM. Gory

and Percheron are equally wrong in stating C. maculata to be a Cape species. The former

inhabits India, and the latter the Mauritius. Many insects are said to be natives of the Cape

of Good Hope, merely because they have been brought from thence.

87. Of the fourth sub-section of Cetonie Cremastocheilidee, we have several Cape species

in the collection ; such as,

89. Let us now return to that Asiatic sub-section, the type of which is C. histrio of

Fabricius. From it we may proceed to that section of the sub-genus Cetonia, which answers

nearly, though not exactly, to a groupe which Mr. Kirby has indicated under the name of

Polybaphes. If this learned entomologist had attempted to give his Polybaphes a character,

he probably would not have joined C. histrio with C. equinoctialis ; but nothing is so easy as

to follow the indolent plan invented by M. Dejean of giving to groupes generic names unac-

companied by descriptions. I hold in utter contempt that privilege of naming for which

naturalists are so much in the habit of squabbling; and, on the contrary, am always grateful

to those persons who kindly provide me with an unobjectionable word. Nevertheless, 1 am

bound to protest against any name that is published without. a character; since it ought not

to be of the slightest authority in the science. It certainly is not the individual placing two

Greek words barbarously in juxta-position who deserves the credit of discovering a genus,

but he who accurately distinguishes the groupe, to which that barbarous name is given, from

all others. With respect, however, to the beautiful groupe which Mr. Kirby has called

Poryzpapuss, I am disposed to retain the name, and shall perch, therefore say, in addition,

that I am acquainted with three sub-sections of it.

The following Cape species belong to the third sub-section :—

Scarabeus baliteatus, Degeer, vii. 642. tab. 48. fig. 4.

Cetonia controversa, G.P. p. 246. tab. 46, fig. 6.

Nore. I do not allude here to Schénnherr, because his ‘Synonymia Insectorum” is altogether wrong

with respect to the species of this particular section Polybaphee.

G.P. p. 246. tab. 46. fig. 5.

Cetonia flammea, Zool. Journ. vol. 2. p. 237. tab. 9. fig. 2.

90. As this last-mentioned section of the sub-genus Cetoninus bears a resemblance in form to

Diplognatha, and represents the genus Macrominus, so the section to which we now pass bears

a strong resemblance to Lomaptera in the genus Gymnetinus which is here represented. This

section I have therefore called GyMNETIDES, and it belongs typically to Madagascar, although

found also in New Holland. There are several known sub-sections; but as they present no

Cape insects, I need not detail them here. I shall only say, that the Cetonte Gymnetidee, by

their beautiful form and polished flat elytra, with serrated sides, by their often cloven clypeus,

long maxille, and emarginate mentum, close the circle of the genus Cetoninus by uniting them-

selves with the sub-genus Schizorhina, and thus forming the junction between it and the sub-

genus Cetonia.

91. By means of Cetonia cincta of Donovan, we arrive at the only remaining section of

Cetonia, which I have called Typicm, not because they are typical of the sub-genus, but

because they represent the genus Cetoninus, as it were, par excellence. This section is so

numerous as to offer sub-sections, which, however, as may be expected, depend on very

refined and even evanescent considerations. Perhaps, however, 1 have not yet been able to

seize the true characters of distinction ; and, indeed, it is of little consequence, provided I can

explain the series of affinity, which appears to me to be as follows :—

(1 Black. Type, C. morio, Fab.

B.—Typically European. 2 2 Viridizeneous. Type, C. fastuosa, Fab.

(3 Viridizneous spotted with white. Type, C. aurata, Lin.

ae ree S4 Green with white or Piet lines. Type, C. BUEEE Fab.

5 Yellow or black spotted with yellow. Type, C. sinuata, Fab.

92. As we have no species from the Cape of the three first sub-sections, I shall begin with

the one which is here numbered the fifth, and designated “ Nigre flavomaculate vel flave.”

To this beautiful African groupe belong the following described species :—1l. Cetonia punctato-

marginata, Degeer; C. impressa, G. P.; C. inscripta, G. P.; C. marginata, Fab.; C.

postica, G. P.; C. fimbriata, G. P.; C. monacha, G. P.; C. fasciata, Fab. (Savigny,

G. P.); C. olivacea, Ol.; C. interrupta, Fab., &c. &c.; and also the following species

brought from the Cape by Dr. Smith :—

Sp. 49. (Cetoninus) Cetonia sinuata, Oliv.

Descr. Cetonia nigrofusca, thoracis elytrorumque margine, thoracis maculis quinque, scutelli

duabus, elytrorumque quatuor flavis, thoracis maculis marginalibus elytrorumque duabus

30 ON THE CETONIIDZ OF SOUTH AFRICA.

Norn. This well known species is subject to very great variation in the discal spots of the thorax,

which are all five placed in a triangle thus s; the two reniform middle ones being the largest and

most constant, although even they will sometimes disappear.

Var. a. Thorax with only the two reniform middle spots. Cetonia sinuata, G.P. p. 182.

Nore. I do not here refer to Gory’s figure, because it wants these two thoracic yellow spots, although

they are expressly mentioned in his description.

Var. f. Thorax without any discal yellow spots. Cetonia sinuata, G. P. tab. 82. fig. 5.

Var. y. Thorax wanting the vertical yellow point, but having the four lower.

Nore. In this variety the triangular lower yellow spots of the elytra extend so as almost to meet the

corresponding enlargement of the marginal vitta, and thus to form as it were a band.

Var. 6. Thorax wanting the two lower spots, but having the three vertical ones.

Norr. I may here observe that the Scarabeus punctato-marginatus of Degeer, appears, as Schonnherr

thought, to be another variety of C. sinuata, Fab. It is in my collection, and may be easily known

by having no yellow points either on the thorax or scutellum. I am in possession of a series of specimens,

that makes me think the following species communicated by Mr. Hope to MM. Gory and Percheron,

may only be another variety ; although it is more in consonance with nature to imagine that all these

varieties are formed, like those of certain flowers, by the crossing of two very contiguous species, the

two parents of all the intermediate varieties being as it were, O. sinwata, as I have described it, and the

C. flaviwentris of MM. Gory and Percheron.

Nork. This species comes the nearest to Cetonia impressa of Goldfuss and Gory, but differs much in

the marking of the elytra. Being in possession of that species also, I have had no difficulty in deter-

mining the distinction that exists between the two.

Cetonia carmelita, G. P. p. 238. tab. 45. fig. 2.

Nore. This is the C. badia of Burchell; and most likely Schénnherr is right in considering it to be

the Scarabeus rufus of Degeer. It is easily known from other three species that come very close to it,

by the two large white anal spots.

Sp. 58. (Cetoninus) Cetonia bachypinica, Burchell.

Cetonia bachypinica, G. P. p. 287. tab. 45. fig. 1.

Nor. The testaceous or yellow colour of this species, passes off in some varieties to green. And I

wish to remark here, in general, that the black colour of some African species, such as C. marginata,

Fab. for instance, becomes brick red, as in C. carmelita, Fab. and passes off to ochry yellow, as in

C. bachypinica, which again passes into green, as in O. aulica, Fab., and so to the viridieeneous colour,

such as C. fastwosa, Fab. which returns to black, as in C. morio, Fab.

93. We shall now proceed to the last sub-section we have to allude to among the Cetonie

typice, that is, to those species which are generally of a green colour, and are marked with

white or yellow lines. Dr. Smith has brought the following :—

spots on the anal plate.

body covered with hair, and which form that section of the sub-genus Cetonia which I have termed

Trichioideew. Thus, therefore, the circle composed of the five sections of Cetonia is complete.

94, We have now gone through a complete revision of all the sub-genera composing the

family of Cetoniide, and which are as follow ; the sub-genera, in italics, being those by which

the passage is made from one genus to the other.

1 TRICHINUS. 2 CETONINUS. 3 GYMNETINUS. 4 MAcRoMINUS. 5 CRYPTODINUS.

1 Osmoderma. 1 Schizorhina. 1 Lomaptera. 1 Oplostomus. 1 Genuchus.

2 Valgus. 2 Coryphe. 2 Agestrata. 2 Anoplocheilus. 2 Cyclidius.

3 Trichius. 3 Goliathus. 3 Philistina. 3 Diplognatha. 3 Cremastocheilus.

4 Campulipus. 4 Ischnostoma. 4 Macronota. 4 Gnathocera. 4 Cryptodus.

5 Platygenia. 5 Cetonia. 5 Gymnetis. 5 Macroma. 5 Cymophorus.

Were nature to set before our eyes every one of these groupes in a state as complete, for instance,

as is that section of Cetonia which I have called Typice, we should, of course, have of the

Cetoniide 125 sections and 625 sub-sections, &c. &c. But this is not the case; since, from

some unexplained cause, each groupe of the same rank contains a different number of species,

and thus throughout the creation we see certain parts of the chain comparatively complete in all

their links, and others again offermg nothing but objects which appear to the superficial

observer at first sight to be insulated, and, in fact, require deep study on the part of the

naturalist before he is enabled to make out their accurate affinities. It is needless to repeat

that I, as well as others before me, haye imagined the cause of this imsulation of particular

objects to arise from the connecting species having been either lost or undiscovered.

95. The conclusion to which we tend by such an analysis as the foregoing, is, that the lowest

H 2

groupe in which species combine will be found, provided all the species are known, to return

into itself, so as to form, as it were, a circle; and if we could suppose no species to be lost or to

remain undiscovered, we should further find five of these lowest groupes to form another circle, and

five of these last circular groupes to form another, and so on until we arrived at that grand

circular groupe which is called the Animal Kingdom. But setting aside this theoretical use of

the foregoing analysis, the practical entomologist will soon discover that in no other way have

we ever had the singularly complicated relations, that exist between the different species of the

natural family of Cetoniide, so well represented. It must not be supposed, however, that I

offer this essay as perfect and complete, or that I absurdly pretend, as some have most unjustly

laid to my charge, to have positively arrived at the Watural System. 1 merely publish this

paper on Cetoniide, as another, and perhaps closer approximation to that Divine plan, which,

every hour I have devoted to nature, whether in tropical forests or in the museums of Europe, has

shewn to be the branch of natural history most worthy of being studied by rational beings.

But the truth is, that this Divine plan is not one particular branch of natural history, but the

study of it necessarily includes the knowledge of every branch. It is the whole, of which each

branch of natural history is but a part, and which I shall ever regard with gratitude, as having

been the source of many moments of the purest pleasure while my residence was in an

unhealthy climate.

ON THE BRACHYUROUS DECAPOD CRUSTACEA.

BROUGHT FROM THE CAPE BY DR. SMITH.

Tue most interesting observations on Crustaceous animals which have of late years been

given to the public are those of Dr. Vaughan Thompson, relating to their metamorphosis.

It had been long recorded that many Entomostraca undergo metamorphosis ; but no naturalist

before Thompson ever ventured to affirm that crabs, lobsters, and the higher Crustacea

generally, pass through certain changes of form after leaving the egg. It is true, that in conse-

quence of the publications of Professor Rathke, some persons disputed the truth of Dr.

Thompson’s assertions; but so far as my own observations allowed me to form an opinion on

the subject, I was ever inclined to think that this gentleman merited well of science, which is far

- more than could be said of any of those persons who by crude inferences, but never by direct obser-

vation, ventured to attack him.* I have never myself lived sufficiently near the sea-side

to enable me conveniently to repeat Dr. Thompson’s experiments ; but looking merely to what

I have seen with my own eyes, I think it will eventually be found that the Ptilota of Aristotle

may be characterized by their change of form taking place during their last two or three stages

of ecdysis; while the metamorphosis of all other Annulosa only occurs during the first or

second moult after leaving the ege. When I come to treat of the Macrourous Decapods, I

shall return to this subject. At present my attention must be more particularly confined to

the classification of the Brachyura, as being the best known groupe of all Crustacea.

M. Latreille and Dr. Leach left systems behind them for the arrangement of Crustacea,

which were professedly artificial, although the former naturalist made several praiseworthy

attempts to arrange these animals naturally. Since the death of these eminent naturalists, two

authors have appeared with higher pretensions to acquaintance with the class. The first of

these, M. Milne Edwards, having previously made some ingenious observations on the

economy and internal anatomy of Crustacea, has lately, in the “ Suites de Buffon,” produced

a classification, of which I can only say, that it makes an approach to be a rare exception to

the well-known fact, that professed comparative anatomists are the persons, of all others, who

in general are the most incapable of using their own observations for purposes of natural

arrangement. And indeed this very arrangement of Edwards is not natural, since he unfortu-

nately conceives that every groupe he can invent, provided he can furnish it with a character,

must be therefore a good one. As, on the contrary, the true definition of a complete natural

groupe is, that it must be a series returning into itself, many of the groupes of Milne Edwards,

when weighed by this scale, will be found wanting. For instance, of his four grand groupes,

Oxyrhynques, Cyclometopes, Catométopes, and Oxystomes, perhaps only his Cyclométopes form a

* The credit of confirming Thompson’s observations belongs to my friend Captain Ducane, R.N., who has made at

Southampton most interesting observations on the Metamorphosis of Crustacea, which I trust he will soon give to the Public.

o4 ON THE BRACHYUROUS DECAPODS OF THE CAPE.

complete natural groupe. Still the “ Histoire Naturelle des Crustacés” is a book full of facts,

which ought to be in the hands of every carcinologist. The second naturalist, above alluded to, is

Professor Dehaan of Leyden. He has treated the subject in another manner, and deserves to be

considered of a more philosophic stamp. What he has published on Crustacea in the Fauna

Japonica is a magnificent tribute to science. Milne Edwards rarely takes notice of any of the

maxille, except the external or fifth pair; and if any objection can be made to Dehaan’s

arrangement, it is that he likewise is not sufficiently eclectic, and appears to make too much

use of the organs of manducation. Nevertheless, as he rigorously follows the mode in which

these organs vary, and not that by which they might arbitrarily be combined, it is satisfactory

to find that the result, generally arrived at, very nearly approaches to the plan of nature.

Nothing further has been published on Crustacea of late years, unless we except some interest-

ing descriptions of new species by MM. Say, Guerin, Bell and others. As for M. Dehaan’s

system, it is not completely worked out ; so that I am obliged to offer the following arrange-

ment, provisionally, as being that by which I have been able to express the affinities which

exist among the Decapods of my own collection. It will at least serve to unite all those rela-

tions, whether of affinity or analogy, which have been recorded by Latreille, Milne Edwards,

and Dehaan, and will prove that, by means of a moderate exercise of patience, order may some-

times be made to arise out of an apparent chaos.

1. The modern art of describing is too often insufferably long, while human life remains short

as ever. I shall endeavour, therefore, as in the former paper, to condense my descriptions as

much as possible.

2. It is only with the normal groupe that we for the present have to concern ourselves. I shall

therefore proceed provisionally to arrange the Brachyura into Stirpes, merely observing, that in

ON THE BRACHYUROUS DECAPODS OF THE CAPE. 53)

the following descriptions I shall rarely allude to colour, since experience has taught me that in

this respect dried specimens of Crustacea are not to be trusted. I would also observe, that as the

groupes of degree next inferior to families—namely, genera—have never been worked out in this

class, I have for the present considered almost all the various groupes under families to be sub-

genera, although some of them, such as Plagusia, may possibly be a true genus, and others again

may prove to be only sections of some sub-genus. I do not think that our collections, as yet,

possess a sufficient quantity of species to allow us to decide what are the genera and what are

the sub-genera of Decapod Crustacea. Professor Dehaan, however, has offered some valuable

hints on the subject, and to those I refer the reader. We appear to enter among the

Brachyura by the genus Mycteris, and to leave it by means of the genus Ranina. There are

ten Brachyurous stirpes, which may be placed in two columns, so as to shew those analogies

which by Milne Edwards and others have too often been taken for affinities.

3. The analogy between certain Jnachina, such as Acanthonyz, and certain Leucosina, such

as Vursia, is so great as to have induced M. Latreille to imagine that a direct affinity existed

between the two groupes. In general, the above analogies appear reversed; but the Tetra-

gonostomous stirpes may be characterized as follows :—

Cephalothorax short, convex, pear-shaped, as broad almost as long, with the sides dentated in

front, and the clypeus short, triangular, with a bidentated apex, having a smaller tooth

on each side.

Orbit without any distinct fossula.

Eyes minute, somewhat prominent, but scarcely moveable, and having a very short peduncle.

Exterior antenne longer than the clypeus, with their first joint reaching its middle, and being

three-sided at the apex, while the second and third joints are cylindrical, and the rest are

short and setaceous.

Internal antenne inserted at the base of the rostrum, and having their basilar joint obconical

and rather three-sided, while their second joint is shorter and cylindrical.

External pedipalpi, or fifth pair of maxille, with their outer palpus semifusiform, and the imner

palpus having the second joint elongated with parallel sides, the third joint subquadrate,

and the tigellus very small, inserted at its inner angle.

Feet, first pair twice as long as body, with the chele thick, having subacute digits, which are

serrulated on the inside. The hinder pairs of feet are more slender.

Abdomen wanting in my specimen, which is a male.

This groupe I have called Antilibinia, because it is in the family Epialtide exactly what

Libinia is in the family Mithracide. It is only analogous to Libinia, for it has no grooves or

orbit for the concealment of the eyes, which besides are neither moveable nor retractile. Lebinia

is a groupe peculiar to the New World; but whether it and Anéélibenia are sub-genera, or only

sections of sub-genera, remains to be proved.

Nore. The shell of this species is without hairs, almost circular, and has the regions in general

distinct. The clypeus is bifurcated with a tooth on each side of the base. The anterior lateral

margin of the shell has three teeth, of which the foremost is situated behind the eyes ; the

second or middle tooth is the greatest, and directed forwards, while the last is little more

than a tubercle. The digestive region has an eminence marked on each side. The branchial

region has five or more tubercles on each side. The cardial region has a tubercle in the middle

behind, and on each side of it there is an oblique portion of the shell scabrose. The horns of

the clypeus are pilose on the inside. The digits of the chele have seven or more teeth on the

inside. ‘The four pair of hind feet have their third joints thick, and are armed with long curved

claws. This crab resembles the Libinia spinosa of Milne Edwards so closely, that at first sight

it might be taken for it.

Nore. The shell of this fine species, which is more than an inch long, is shaped like an heraldic

shield. It is depressed. The two horns of the clypeus are pilose at their apex, and have two

setiferous tubercles at their base. On each side of these horns, and at the external angle of

the orbits, there is a triangular tooth also pilose at the apex. The anterior lateral margins of

the shell are bidentated. The fore teeth on each side are large, triangular, and blunt. From

their points the sides of the carapace proceed towards the posterior margin, nearly parallel

to each other, until they arrive at the second tooth, which is rudimentary, and reduced to a

setiferous tubercle. The posterior margin of the thorax is rounded.

middle of the clypeus ; while the second joint is shorter and obconical.

Internal antenne with the basilar joint subcylindrical, and the second subtriangular.

External pedipalpt with the outer palpus falciform, and the inner palpus having its second joint

with subparallel sides, the third jomt sub-quadrate, emarginate at the apex, with the

tigellus conspicuous, inserted at its inner angle.

pair longer than the first, and, as well as the three posterior pair, it is furnished with a

subcheliform penultimate joint, which is truncated at the apex, and unidentated.

Abdomen of male has seven segments.

This groupe is in the family Mithracide exactly what Acanthonyz is in the family Epial-

tide. Both are analogous groupes in contiguous families ; but whether they ought to be con-

sidered as sub-genera, or only sections of sub-genera, remains yet to be discovered.

and are placed more on the back. There are, moreover, no points on the hinder edge of

the carapace, as in MZ. dichotomus. The eyes are globular, and larger than the base of the

pedicles. The antennary fossa has no tubercle at the posterior edge. The anterior feet are

long, having the third and fourth jomts covered with short spines: the fifth jot or hand is

slender and smooth, as is also the moveable finger without teeth. The other feet have no

tooth at the extremity of the third joint. The size is 14 inch.

6. By means of Hurynome we proceed to the PartaENnoPina ; but of this groupe no species

has been brought from the Cape ; so we avail ourselves of Cryptopoda to pass on to Atthra,

and so among the Cancrina, of which the families appear to be as follow. All these families are

distinguished by having the scapes of the palpi of the fifth maxille unidentated on the outside ;

and their males have the genital orifices hollowed out in the first joints of the hind feet.

Norz. The shell of this crab is about two inches long, and about twice as wide as long, of an

oval form, very convex, and having only the branchial regions distinctly marked. The surface is

quite smooth, of a dirty orange hue, marked with brick-red spots. Of these, one large spot, of

an irregular form, reaches over the genital region almost the whole width of the shell. Another

smaller spot marks the cardiac region, and the remainder of the shell is covered with small

round spots of the same hue, which are also found on the feet. The seven-jointed abdomen of

the female is also marked with small fulvous spots.

The margin of the clypeus is sinuated so as almost to show four rudimentary lobes. The

chele at their points are blackish ; on the fixed joint there are two elevated lines on the out-

side. The other feet are very much compressed and dilated. In other respects the characters

are those common to all the species of the groupe named Atergatis by Professor Dehaan.

This species is two inches long.

distinguished from it by the anterior lateral margin being in this crab scolloped, instead of

having four triangular teeth. The whole of the feet also are granulose, which is not the case

in C. areolatus. The length is about eight lines. This is not the Chlorodius of Dehaan.

Sub-genus. Hatimepe, Dehaan.

Nors. This species is only seven lines long. The thorax is convex in the middle, having the

anterior lateral margins scolloped by four blunt tubercles. The front is sub-acuminate, with

the apex crenated. The chelz are unequal in size, but both large. The abdomen is covered

with hairs, except the last joint.

This species has affinity to the Polydectus cupulifer of Milne Edwards, agreeing with it, in

having three great tubercles surrounding each orbit, one occupying its external angle, and the

two others the lower edge of the orbit.

7, Of the family Cancripm we have no species ; we pass on therefore to the following—

Norg. This species of Eriphia has its carapace well marked by the regions. The whole of it

towards the margin, except behind, is covered with tubercles ; the rest of the surface is granu-

lose. The lateral margin is strongly tuberculated, and the two last tubercles behind the orbits

are almost spines. The margin of the orbit is tuberculated. The margin of the two middle

lobes of the four-lobed clypeus has five tubercles for each. The fore-feet are one larger than

the other. The larger being marked above by tubercles sparingly scattered, and the smaller

being strongly verrucose above and below. The chele of the former has strong teeth; those

of the latter have scarcely any, and cross each other. The feet are spotted with white above,

are hispid, but have no tubercles. The length is more than two inches. The abdomen of the

male is seven-jointed.

Nore. This species also, like the Hriphie in general, has the regions well marked out. The fore

margin of the carapace is tubercled, but not so much so as in the Eriphia Smithii. The Test

of the surface is very finely granulose. The lateral margin has six distinct teeth or spines

before, and some minute tubercles behind. The margin of the orbit is also tuberculated, four

of the tubercles becoming almost teeth. The margin of the two middle lobes of the four-lobed

clypeus has six tubercles for each. The fore-feet are one larger than the other. Both are

almost smooth, although the smaller presents some vestiges of tubercles. The digits of the

chele are black; those of the larger hand have three teeth above and below; those of the lesser

hand being almost without teeth. The feet are without spots or tubercles, but are very hispid.

The length is two inches. The abdomen of the female has seven joints.

The two foregoing species of Eriphia both come close to their congeners, the Gegarcinus

hirtipes of Lamarck, and the Eriphia levimana of Milne Edwards. But these last species are

natives of the Isle of France.

Nors. Although I have here placed Charybdis as a sub-genus, I suspect that when the family

Portunide is worked out, it will be found that the Charybdis of Dehaan is only a section of

some sub-genus of the genus Portuninus. M. Dehaan is here splitting very fine ; for between

the groupes named by him Oceanus, Charybdis, and Thalamita, the differences are very

minute. Our crab comes between Oceanus crucifer of Dehaan and his Charybdis 6-dentatus.

The cephalothorax has no transverse granulated lines like the latter, nor are the teeth of the

clypeus blunt like those of Oceanus crucifer. The six teeth of the anterior lateral margin are

equal, the tooth nearest the eye being sharp. So are the teeth of the clypeus, and the four

middle of these teeth are scarcely separated from the lateral ones by a deeper incision. The

fore-feet are equal in size, having two apical teeth on the upper margin of the fourth joint. The

length is about two inches. The abdomen of the female has six joints.

Nore. This crab has a strong relation to the Corystide, which Professor Dehaan has pointed

out with his usual acumen. By Anisopus, in fact, we pass off to the Corystina among the

Trigonostomous Brachyura.

Sub-genus. Xatva, M‘L.

Cephalothorax rather depressed, as broad as long, but narrower behind, being broadest in the

middle, and having the sides in front arched with a five-toothed margin; the tooth behind

the eyes being broad and truncated. The sides behind are entire, rather concave, and

with a margin. The shell behind is also entire and margined. The clypeus is triangular,

advanced with an acute point, and having the sides undated, while it is furnished above

on each side at its base with an orbital tooth.

Orbit with two teeth below, the outer one of which is triangular, and larger than the other.

External antenne inserted within the orbit, and having their basilar joint short and sub-

triangular.

External pedipalpi, with the second joint, almost twice as long as the third, which is sub-

quadrate, carinated at the base, with the point obliquely truncated, acummated on the

outside ; the inner margin having a piece cut out,as it were, above its middle.

Feet, first pair with the chele bicarinated above; second, third, and fourth pair with slender

nails, while the hind pair has the nails or ungues dilated and pointed as in the genus

Carcinus.

Abdomen of male has seven segments; but the third, fourth, and fifth appear soldered together.

Xaiva is the Spanish name for all crabs which have the posterior feet natatory. This will

be seen on referring to the curious work of Parra on the natural history of the Gulf of Mexico.

The present sub-genus comes close to Carcinus of Leach; but is easily distinguished by

the third joint of the external pedipalpi.

Nore. The stomachal region in this pretty little crab is marked by four tubercles, which are

situated on an elevated ridge, stretching on each side towards a lateral tubercle, which is almost

on the middle tooth of the anterior lateral margin of the shell. The genital region is marked by

two minute tubercles at the base of a longitudinal carina. An irregular transverse carina

stretches out on each side from the last lateral marginal tooth towards the middle of the shell,

marking out the upper limit of the branchial region. The chele are marked above with five

keels on the fixed digit, and three or four longitudinal furrows on the middle finger. The

second, third, and fourth pair of feet, are compressed, having their third and fourth joints

bicarinated, and their ungues furrowed. The fifth pair of feet are less bicarinated, and the

last joint or claw is like the posterior claw of Carcinus menas, Leach, only more broad.

The length is less than an inch.

8. We now return to the aberrant family Evriphide, by means of which we pass to Thelphusa

among the Grapsina. It becomes therefore necessary to point out the families of a stirps

which is very common in warm climates, and the study of whose manners afforded me much

amusement whilst I resided in the West Indies. Dr. Milne Edwards calls them Catamétopes,

and says that some of them are “complétement terrestres.” This is an error, however; for all

these crabs must lay their eggs in water, must pass their infant state in water, and must,

during their future life, return periodically to the vicinity of water. The land-crab par excel-

lence, G'egarcinus ruricola, Lat., in this respect, does not differ in economy from other

Brachyurous Decapods, nor does it retire many leagues from the sea. In our small West

India islands it may be found all over them ; but in Cuba it has its limits, which are confined

to a certain distance from the shore.

Gegarcinide. ‘The first family Thelphuside has the genital organs of the male placed nearly

as in the last stirps Cancrina, with which it is osculant. But the other families of Grapsina

have the genital orifices of the male placed in a transverse groove hollowed out on the

sternum. Both the Thelphuside and Gonoplacide being aberrant families, agree with the

Cancrina in having the scape of their palpi unidentated on the inside.

still more small and evanescent than in the female. I may take this occasion to observe, that

in my cabinet I separate those species of Thelphusa, which, like the present, have a transversal

true Thelphuse, of which the type is the European species Thelphusa fluviatilis. —

Cephalothorax sub-quadrate, with the back convex, and entire sides which are arched towards

Exterior Antenne produced as far as the middle between the eyes, and having the first joint

transverse.

External Pedipalpi very distant from each other; with the second joint very oblique at the

base, at the point sinuated, and of the same length as the third joint, which is concave in

the middle, and has a bearded crest continuous along its inner edge as far as the outer

part of the base of the second joint.

Feet; first pair with thick and equal chele.

Abdomen in both sexes has seven segments.

10. Dehaan has noticed the affinity between the two groupes, which he names Chasmagnathus

and Pachysoma. By them he passes from the family Ocypodide to the family Grapside.

The sub-genus or sub-section which I have just characterized under the name of Gnathochasmus

comes exactly between Chasmagnathus and Pachysoma. It agrees with both in the remark-

able elevated crest, which stretches down obliquely from the inner angle of the third jomt of

the external pedipalp to the outer angle of the base of its second joint. It has the thorax with

arched sides, like those of Chasmagnathus ; but then these sides are entire, like those of

Pachysoma. I may here observe, that Dehaan’s name Pachysoma ought to be changed, as it

was assigned, long ago, by Mr. Kirby, to a division of the genus Scarabeus. See Hore

Norr. It is singular that I can find no good character whereby to separate this Cape crab from

the American species described by Bose and Say. The latter, however, I only know from descrip-

tion. It is six lmes long, whereas the Cape crab is more than aninch. Both are distinguished

from the Sesarma quadrata by their epistome being covered with granulations, so as to appear

finely reticulated. I dare say if we could compare the two crabs together we should be able

to discover a specific difference. The Cape crab has not the slightest vestige of granulation on

the shell of the cephalothorax. I have found in Cuba the species of Sesarma to live generally

under stones on the banks of the muddy mouths of rivers. Say’s name, Sesarma, is adopted

by me instead of Pachysoma. It distinguishes a groupe which is the most quadrilateral form

of the family Grapside, and easily known from the true Grapsus by its sides deflexed verti-

cally, being parallel to each other from the eyes. In the Cape species the clypeus has four

lobes, the two middle ones being separated by a deep furrow.

Norte. This species is nearly three inches long, and very handsome. The manners of the vari-

ous species of Goniopsis are very interesting. There are no crabs more active, more vigilant, or

more beautiful. The type of this genus is the Grapsus ruricola of Degeer, a crab whose

manners are detailed by me in the first volume of the Transactions of the Zoological Society.

The name, Grapsus ruricola, Deg., was wrongly altered from my manuscript by some person

who superintended the press during my absence at the Havana, and changed the name to

Gegarcinus ruricola, Desm. The Grapsus ruricola, Deg., is the Grapsus eruentatus of Latreille,

and the true Crabe des Paletuviers of French travellers, although Milne Edwards erroneously

makes this to be the Goniopsis picta, a species which on the contrary is always found on reefs,

and which is therefore by Parra called “ Cangrejo de Arrecife.”

Norz. This species is seven lines long, and as broad as long. I believe that many species

of this sub-genus are confounded with the Cancer minutus of Fabricius. Vautilograpsus is

an excellent groupe, which appears to have escaped the notice of M. Dehaan. It is in general

found in the wide ocean, adhering to chelonian reptiles or masses of floating sea-weed. The

feet therefore are almost natatorial. Grapsus pusillus of Dehaan appears to be a species of

the sub-genus near to Wautilograpsus major above described.

Sub-genus. Grapsittus, M‘L.

Cephalothorax heart-shaped, depressed, with the back plane and the sides arched, almost form-

ing the quadrant of a circle; the clypeus is broad, truncated, and sinuated in front.

Orbits placed at the fore angles of the shell, with great depressed eyes.

Exterior Antenne placed without the orbit towards the middle of the clypeus.

Internal Antenne rather thick.

External Pedipalpi with the second and third joints quadrate, almost equal, the third being a

little shorter; the third joint also has its inner apex rounded off, the tigellus is thick, and

the outer palpus has its sides almost parallel.

Feet; first pair almost twice as long as body with very large jomts; the chele being without

teeth and the other feet being short with hairy tarsi.

Abdomen in males has five segments, in females it has six.

11. This groupe is very distinct from any described one with which I am acquainted. It

approaches in many respects to Mautilograpsus, and appears to connect that groupe with

Plagusia. It is remarkable for the large size of the fore feet.

12. The above great number of Grapsid@ at the Cape shews that the carcinology of South

Africa agrees with that of itratropical climates more than it does with that of the temperate

zones in general. But we now proceed to the stirps Pinnotherina, and for that purpose we

must return to the family Ocypodide. Milne Edwards has shewn that a small crab of the

Red Sea, called by him Doto sulcatus, makes the passage from the Ocypodide to the

Pinnotherina.

Stirps. PINNOTHERINA, Dehaan, or ParasiticaL Crass.

13. This stirps contains so few known species, that I shall not attempt its arrangement at

present, more particularly as Dr. Smith has only brought home one species, which has long

been known as a native of the Cape of Good Hope. M. Dehaan makes the distinguishing

characteristic of this stirps, which he calls Pinnotheridea, to consist in the sixth joint of the

fourth pair of maxille being inserted at the base of the fifth jomt. The groupe consists of

singular crabs, among which we find the last pair of feet to be sometimes evanescent, as in the

genus Hexapus of Dehaan.

14. Perhaps when the attention of collectors shall have been more directed to these small,

though curious crabs, we may discover their natural arrangement. The difficulties pomted out

by Milne Edwards, who complains that his genera are so distinct from each other, evidently pro-

ceeds from almost every one of his genera belonging to a distinct family. Perhaps indeed, if we

consider his arrangement in this light—in other words, that most of his genera represent fami-

lies—the table he gives (vol. 2, p. 29) may not be found so far wrong. But however this mary

be, I shall now return to the stirps Cancrina and family Carcinide. From these we pass

directly to the osculant stirps Corystina, belonging to the interesting tribe of Trigonostomous

Brachyura, which may be displayed to view in the following manner :—

15. From the Corystina we pass to the Calappina, by means of Matuta. By Oreophorus we

leave the Calappina for the Leucosina. The passage from the Leucosina to the Dromiina is

not so clear; but these last are close to the Dorippina, which last again are approximated

naturally to the Corystina. Still the tribe has never been worked out, and I think it more

than’ possible that the Dromiina which I have here considered to be an aberrant groupe of

Trigonostomous Brachyura, will, in the end, be found to be an aberrant groupe of Anomurous

Macroura. Nay, this last is the position assigned to it by Milne Edwards, and the arguments

for such a location of Dromiina are their rudiment , abdominal appendages, and the oral orifice

being rarely triangular. On the other hand, however, they differ from all Macroura in having

fossulee for the reception of their internal antennze. The question therefore of their true place can

only be determined when the groupe shall have been worked out, which I fear cannot be done at

present, on account of the paucity of species which are known to belong to this essentially tropical

tribe. One thing, nevertheless, is established, namely, that the Dromiina are osculant, or, in other

words, they stand on the limits of the Trigonostomous Brachyura and Anomurous Macroura.

Into which of these circles the stirps truly enters, must be left for future investigation ; but

I shall provisionally consider it as belonging to the Brachyura. As for the families of

Trigonostomous Brachyura, I shall not at present attempt to indicate them, but proceed at

once to characterize the sub-genera brought from the Cape, which are only three.

Stirps. CORYSTINA.

Of the stirps Corystina we have no species from the Cape; but the following is very close

to it, being aberrant in the next stirps.

species confounded together under the name of Matuta victor. Ido not consider the above

names of the family and genus to possess any authority, and merely publish them in order that

the reader may understand the relation which the sub-genus bears to the stirps Calappina.

Stirps. LEUCOSINA.

Here likewise I shall not pretend to characterize the families, or to describe the genera of a

stirps in which so few species are as yet known; but shall merely content myself with the

following description of the only sub-genus of the groupe which is known to be found at

the Cape of Good Hope :—

Sub-genus. Leveisca, M‘L.

Body in front slender and compressed, but behind thick.

Cephalothoraz smooth, plane, depressed, sub-elliptical, broader than long, and having a thin

reflexed margin; while the clypeus is advanced with a round sub-reflexed apex, which is

scarcely emarginate.

Orbits small, sub-circular, and hidden under the clypeus; while the eyes are deeply set, very

minute and globose.

Exterior Antenne very small and rather tri-articulate.

Interior Antenne hidden under the clypeus in transverse reniform fossule.

External Pedipalpi very large, and closing a triangular buccal cavity; their second joint is

oblong, quadrate, and broader in front than the third, which is an ane with a sharp

point, while the external palpus is lunate.

Feet; first, second, and third pairs have been lost in the only specimen before me; but the

two remaining pair are short, and all are inserted under the margin of the cephalothorax.

Abdomen of the female with four segments.

The nearest crab to this is one from the Red Sea, which is described by Riippell under the

name of Oreophorus horridus. Both come near to Calappina.

much injured, having lost the chele, and several other of the feet. The abdomen also is

in a damaged state.

of Dromia differs from that of the Brachyura in general.

Norte. This species comes very near one from the Red Sea, described by Ruppell under the

name of Dromia unidentata; but the anterior sides of the shell have not an unidentated margin.

The crab is all, except the tips of the fore feet, covered with a close, short, brown tomen-

tum. The shell is round, with a convex globular back. Besides the two middle triangular

teeth of the clypeus, there is a short blunt one above the inner side of the orbit, and

vestiges of another blunt tooth above the outer side. The length is about sixteen lines.

Dr. Smith has brought no species of the stirps Dorippina from the Cape.

ON A NEW SPECIES OF CERAPTERUS.

Tue addition of a new species to. so rare a genus as Cerapterus will confer entomological

fame on Dr. Smith’s expedition. The genus Cerapterus is so little understood by entomolo-

gists, that ere I describe this new species I conceive myself called upon to make a few remarks

on the groupe, particularly as those hitherto made have either been extremely inaccurate, or

have been accompanied by bad figures.

The genus Cerapterus was founded by Swederus fifty years ago, and the insects having

immediate reference to it remain to this day of the utmost rarity; so much so, indeed, that

I believe there is no specimen in any Continental Museum. There are only five specimens

in England, and each of these belongs to a distinct species. Of these five specimens, three

are in my collection, one in that of the East India Company, and one in that of Mr. John

Curtis. Having the first four species now on the table before me, I consider myself enabled

to distinguish the species accurately; and I shall take the opportunity of stating some

interesting particulars observed by my brother, Mr. George MacLeay, in New South Wales,

which agree with the observations made by M. Verreaux on the economy of the Pausside in

general,—a family of which he has brought home a very extensive collection.

Being in possession of a fine series of undescribed Pausside, and finding some very

curious forms among them, I shall probably hereafter treat of the family at large in some other

work. My object for the present must be confined to a satisfactory description of Dr. Smith’s

new species. I shall therefore in this place merely remark, that if we watch that chain of

affinity which is most visible in the family of Paussid@, some genera that are usually included

in it will seem, so far as we are acquainted with the groupe, to be more properly excluded.

For instance, beginning with the true genus Paussus, we pass, by an easy transition, to the

groupe called Platyrhopalus by Mr. Westwood, and to that interesting insect Platyrhopalus

Mellyi, which appears to be the type of a new sub-genus leading us on directly to Cerap-

terus latipes of Swederus; and by the New Holland form of Cerapterus which I call Arthrop-

terus, we pass to Pentaplatarthrus, from which we return to Paussus. Now, as this returning

into itself is the essential characteristic of a natural groupe, it follows that the genus Aylo-

torus of Dalman, as well as the Trochoideus of Westwood, are osculant groupes, leading off

from the Pausside, since if inserted in the above circular series, they appear to interrupt it.

If indeed Dalman’s name Hylotorus be correctly applied, this insect cannot enter into the

groupe of true Pausside, which, according to the observations of M. Verreaux, never attack

wood. As to the genus Trochoideus, which, by the way, is strangely named; for the insects

are as like to Hercules as to a wheel; it certainly leads off to the parasitical Myrmecoxenus of

Chevrolat, and other genera, such as Cryptophagus, of the groupe which I have called Wecro-

phaga. Mr. Westwood seems to have been the first to suspect the affinity of Cryptophagus to the

Pausside, but he has not expressed himself very clearly on the subject. With respect to the

true affinities of Hylotorus, having never seen the insect except as figured by Schonnherr in

his appendix, [ am unwilling to offer an opinion; although, if Dalman’s name has been given to

the genus on account of its habits, I suspect that good reasons may hereafter be found for

this last entomologist’s assertion, that it bears some kind of relation to Platypus. One thing,

however, is sure, namely, that the Pausside have a strong relation of analogy to the Pselaphide ;

so strong indeed, that I at one time suspected immediate affinity. But I shall return to this

subject anon. | .

I have taken care that figures of the greatest accuracy, and made under my own superin-

tendence, should be executed by Mr. C. Curtis, an artist whose skill in such subjects is only

rivalled by that of his brother. I wished also to render the following observations still

more complete, by presenting entomologists with the anatomy of the mouth; but as I hope

soon to have several specimens at my disposal for dissection, I am unwilling to sacrifice

valuable insects, which are, so far as I know, at present unique in my cabinet.

Those persons who may wish to possess some notion of the actual state of our knowledge

with respect to Cerapterus, will do well to cast their eye over a paper on Pausside, published

in the 16th volume of the Linnean Transactions. It would be unjust to a clever entomologist,

Mr, Westwood, did I not praise the industry with which he has there brought together

almost every word that has been written on these rare insects. I trust he will now confer a

further favour on the entomological world, by condensing the materials he has so laboriously

compiled, and by arranging his own valuable observations in a lucid order. His reasoning,

however, ought all to be unsparingly expunged ; for Mr. Westwood, when he draws an infer-

ence, is even more awful than when he names his Pauss?.*

In the Cerapterus of authors I can clearly discern two very distinct sub-genera. But I shall

first state the external characters common to both. They are as follow :—

Antenne pubescentes capitis fronti inserte, 10-articulate articulo primo augustiore com-

presso apice emarginato reliquis sub-perpendiculari, articulo ultimo apice semicircu-

lari antenne totius partem fere quartam plerumque constituente articulorumque inter-

mediorum latitudine gaudente, his equalibus brevibus compressis latissimis sub-

parallelis. Caput subtriangulare collo cylindrico instructum. Oculi globosi valde

prominuli. Thorax planiusculus immarginatus. Scutellum triangulare. Elytra

oblongo-quadrata. Pedes valde compressi, lati. Tarsi tetrameri, filiformes articulo

ultimo longiore simplice. Ungues simplices.

Such insects are peculiar to the tropics of the Old World and to New Holland, and I

distribute them as follows :—

Sub-genus. CERAPTERUS, Swederus.

Caput thorace angustius, collo brevi, oculis mediocribus. Thorax latior quam longus

* For instance, he has attempted to prove, although I know not how, that the Paussi presented to Latreille by my father,

were given to the latter out of the Linnean Collection by its purchaser, Sir J. E. Smith. Mr. Westwood accord-

ingly vents a great deal of virtuous indignation, which however is all wasted, as my father never received an insect in his

life from Sir James Smith ; and I must say it is rather hard that the late President of the Linnean Society should be so

unjustly attacked in the Transactions of an Institution which he founded.

Nore. The original specimen which General Davies sent to Swederus for description is now

in my collection, my father having purchased it at the sale of the General’s museum. It is

supposed to be a native of the East Indies, which is more than probable, as it comes very close

to the Javanese species hereafter described.

Norte. The only specimen known of this insect was brought by Dr. Horsfield from Java, and

deposited by him in the museum of the East India Company. It was first described by Mr.

Westwood, who imagined it to be a variety of Cerapterus latipes. He proposed, however, if it

should eventually be proved different, that it should be called C. Horsfieldit; and this

proposal I have had great pleasure in adopting, out of respect for the profound entomological

science of Dr. Horsfield. The figure given in the Linnean Transactions of this interesting

insect is so incorrect, that I have, with Dr. Horsfield’s kind permission, employed Mr. C. Curtis

to make an accurate one for the satisfaction of entomologists. The size is that of the former

species, that is, rather more than five lines.

Nore. For an unique specimen of this African species I am indebted to the kindness of Dr.

Smith, who found it within the tropic of Capricorn. It is by far the largest of the Pausside

known, and differs from the two former species of Cerapterus in having a spine at the extremity

of the tibia. It seems to form a distinct section of Cerapterus.

Norz. The only specimen known of this species was purchased by my father at the sale of Mr.

Francillon’s museum. None of the authors who have written on the species ever saw it,

except Donovan, who was its first describer in his work on the “Insects of New Holland.”

There is another species of Arthropterus, which I have seen in the valuable collection of my

friend Mr. John Curtis, and which differs from A. MacZLeaii in the form of the thorax, and in

the body being more depressed. I am ignorant which of these two my brother, Mr. George

MacLeay, has lately found, or whether his discovery may not prove, on comparison, to be still

a third species. But I learn, by a letter from my father, that my brother, “in one of his late

excursions into the terior of New South Wales, discovered several specimens of ‘ Cerap-

terus MacLeazi’ in the nests of ants, and, moreover, remarked, that when alive they had the

power of exploding, after the manner of Brachini.’”’ The first of these observations with

respect to the economy of Arthropterus agrees perfectly with what M. Verreaux noticed of the

Paussi of the Cape ; and my brother’s second observation accords with that of M. Dupont’s

correspondent on the Senegal species, Paussus excavatus. I hope, however, as I am about to

visit Australia, soon to be able to make myself master of the economy of these interesting

insects, and also to publish a correct representation of the parts of their mouth.

PROSPECTUS. 0° 2 0 eam

Tue Cape of Good Hope is now acknowledged to be one of the greatest avenues as yet opened for the

researches of the Naturalist. Our Colony in that part of Southern Africa is the key to a large portion of |

an extensive continent which is still but very partially explored; and the field to which it admits the

eae scientific traveller is rich to exuberance in the variety and novelty, both of animal and vegetable life.

i: Ha S| es Stimulated by the prospect of Discovery in a quarter so fertile in interest, “ Zhe Cape of Good Hope

Hage ap Association for Exploring Cental Africa” was established in 1833; and in 1886, an Expedition fitted

out by that body, consisting of thirty-four persons, and directed by Dr. Smith, after an absence of

nineteen months, and penetrasing as far as 23° 28' South latitude, returned to Cape Town laden with

al SE fe Sk

a variety of curious and important specimens in Natural History, &c.

Previously to this period little mformation has been furnished, in a shape calculated to enable the

public to form accurate ideas of the various animated begs by which these regions are inhabited. The

splendid publication of Le Vaillant, no doubt, should be mentioned as forming an exception, pro tanto ;

but this includes only a portion of the Birds of the most southern extremity of the country, and a work

‘us . . therefore extensive enough to comprehend the various departments of Zoology is still a desideratum.

The Members of The Cape of Good Hope Association for Kxploring Central Africa found themselves,

on the return of the recent Expedition, in a situation to supply at least some portion of the- existing

} deficiencies ; but their funds, even if it had been possible to divert them to such an object, were altogether

=| inadecuate to defray the expense of laying the result of their labours before the world. Under such

. . circuinstances, it was decided that Dr. Smith, the director of the Expedition, should be authorised, on

ce his arrival in England, to wait upon Lord Glenelg, for the purpose of making him acquainted with

4 the position and views of the Society, in the hope that Government might be induced to assist in the

; publication of their materials. . ‘

Sate! i an! - This hope has not been disappointed, At the recommendation of the Secretary of State for the

3 Colonial Department, the Lords Commissioners of Her Majesty’s Treasury have been pleased, by a ~

pecuniary grant, to enable the Society to publish the result of its labours, without infringing upon the -

_ funds raised solely for the purposes of discovery ; and in a form which, while it places the work

within reach of most of the friends and promoters of science, will not, it is hoped, be found inconsistent

with the interest and importance of the subject.

The materials for the work now offered, under such patronage, to the public, will consist of pictorial

kad illustrations of between three and four hundred subjects of the animal Kingdom, all of ator have been

i oy tl } collected to the south of 23° 28’ South latitude; and will comprise,

ik First, and principally, unknown animals ; aah

Secondly, animals known, but not yet figured ; and ; et Wee

Lastly, such as have been imperfectly figured ; but. of w hich the Society is in possession of accurate ; te

drawings. .

The Entomological portion of the work will be from the pen of W. S. Macleay: Ksq., who has

kindly undertaken that department. The rest of the descriptions will be furnished by Dr. Smith, who

will add a summary of African Zoology, and an inquiry into the Geographical ranges of species in. that

quarter of the Globe. : y

Conditions of Publication.

The Work will appear periodically ; and it is estiinated that the* whole will be completed in

about thirty-four parts. As it will be necessary that the plates be published promisenously, they —

will be arranged in five divisions, viz. Mammania, Avus, Piscms, Repritia, and INVERTEBRATE.

The plates of each of these divisions will bo numbered independently, and the letter-press deseriptions left ti aoe ae

unpaged, so that on the worl being completed, they may be arranged either agreeably to the general classified

order which will accompany the last number, or ace ording to the particular views of the purchasers,
