Synopsis of Phasmidæ.


HAVING been recently led to study the singular and interesting family of Orthopterous Insects, termed Phasmidæ, in order to elucidate the characters of' the sixteen species described in the first part of my `Entomology of Australia,' I have been induced to arrange the materials collected for that purpose in the form of an Essay, the object of which is to present a complete list of all the recorded insects belonging to the family, and to embrace at the same time descriptions of a considerable number of new forms which have fallen under my observation. The result of my researches may form a not uninteresting addition to the small stock of knowledge at present possessed by entomologists with regard to this striking but neglected group.

Of the extent of this knowledge, and its gradual development, some idea may be formed from the following outline of what has been written upon the subject since the days of Linnæus, who first placed these insects in the genus Gryllus, but afterwards removed them to that of Mantis. In this latter mode of arrangement he was followed by Gmelin, and by Fabricius in his earlier publications; but in the year 1787, Stoll, in his `Réprésentations exactement coloriées d'après Nature des Spectres,' &c., proposed to form the Spectres into a distinct family (genus) from Mantis. To this genus, in the commencement of his work, he gave the name of Spectrum: at the end, however, he gave a list of the species figured by him from various Dutch collections, and amounting in number to 27, with Latin specific names, to which he prefixed the generic appellation of Phasma. He divided the genus thus formed into two families, characterized as follows:

“1. Les pieds antérieurs plus longs que les postérieurs; le corps tout à fait cylindrique.

“2. Le corps plat; les pieds antérieurs plus courts que les postérieurs. Dans quelques espèces les femelles ont les étuis aussi longs que les ailes.”

In the `Entomologia Systematica emendata et aucta,' of Fabricius, published in 1793, and consequently some years after its date, the preceding work is left unnoticed; but the Supplement, published in 1798, contains references to a few*
* Although, as I have stated above, Stoll figured 27 species of Phasma, Fabricius referred to only 8 of these figures; and Lichtenstein, in the paper subsequently adverted to, to only 18. For what reason these two authors, referring to some of Stoll's figures, wholly neglected the remainder, I am at a loss to conceive. It seems, however, to be a rule with some naturalists, when writing monographs or general systematic works, to mention those species only which they know, by ocular demonstration, to exist; and thus many unique or very rare insects, which have been described by various authors from time to time, have been omitted from the general catalogues, and almost lost to science, until recovered by a fortunate chance. In my Synopsis of this family I have carefully referred to all Stoll's figures, and indeed, as far as my knowledge extends, to every figure or description that exists in scientific works, whether I have myself seen individuals of the species or not.
of the figures given

by Stoll, and exhibits the Spectres as a distinct genus from Mantis, under the name of Phasma, although without any indication from whence that name was derived. In this work, Fabricius enumerates only 16 species of the genus, and places the apterous before the winged.

The `Transactions of the Linnean Society' for 1802 contain a monograph of this family by Dr. Lichtenstein, entitled “ A Dissertation on two natural Genera hitherto confounded under the Name of Mantis,” in which the learned author avows that the idea of separating the Spectres did not originate with him, but with Stoll. In common with Fabricius, he neglects a considerable number of Stoll's figures, and describes in all only 25 species, which he arranges in the following manner:
“Phasma.
* TERETIA. Pedibus anticis longissimis tenuibus compressis.
Aptera. Elytris alisque in utroque sexu nullis. [Ph. filiformis, &c.]
†† Subaptera. Elytris at alis nullis. [Ph. angulatum.]
††† Alata. Elytris alisque in utroque sexu. [Ph. Gigas, &c.]
** DEPRESSA. Abdomine lato, depresso; pedibus anticis brevibus latis depressis; thorace brevi. (Hæc aliquanto similiora Mantibus quam antecedentia Teretia.) [Ph. Dracunculus et citrifolium.]”

It is singular that this paper has not been referred to by subsequent systematists, except by Latreille, in the entomological department of Cuvier's `Règne Animal.'

The profound entomologist just named, in his first great work, `Genera Crustaceorum et Insectorum,' 1807, proposed to arrange these insects as follows:
“MANTIDES.
 I. SPECTRA.
  Genus Phasma.

  1. Pedes femoribus tibiisque haud alatis; illorum lateribus non dilatato-membranaceis.
    Page 3
    1. Alata aut saltem elytrata (elytris sæpissime brevissimis).
      Ph. angulata, Gigas, necydaloides, &c.
    2. Corpus elytris alisque nullis.
      1. Antennæ setaceæ, elongatæ, articulis numerosissimis.
        Ph. filiformis, Ferula, Calamus.
      2. Antennæ conico-subulatæ, brevissimæ, articulis duodecim.
        Ph. Rossia.
  2. Pedes femoribus tibiisque alatis sive membrana externe et intus auctis.
    Stoll, Mant. tab. 5. fig. 18. - tab. 18. fig. 65.”

Then follows the genus Phyllium.

While in the first edition of the `Règne Animal' he classifies them in the following manner:
“ORTHOPTERA.
  CURSORIA.
   Gen. MANTIS.
    Gen. Spectrum.
     Gen. Phasma.
     Gen. Phyllium”

And this arrangement is retained in the second edition, with this slight difference, that Phasma and Phyllium are no longer regarded as genera, but as subgenera of Spectrum, itself a subgenus of Mantis, one of the three genera which constitute the family of Cursoria.

In the 10th volume of the `Encyclopédie Méthodique,' MM. Lepelletier and Serville propose the following plan of classification, which includes several new genera:

  1. “Trois ocelles très distincts.
    Phasma.
  2. Point d'ocelles distincts.
    1. Corps ailé on ayant au moins des élytres.
      1. Prothorax égalant presqu'en longueur le mésothorax.
        Phyllium.
      2. Prothorax plus long que la moitié du mésothorax.
        Prisopus.
      3. Prothorax court, n'égalant pas en longueur la moitié du mésothorax.
        Cladoxerus.
        Cyphocrana.
    2. Corps aptère, sans ailes ni élytres.
      Bacteria.
      Bacillus.”

Page 4
Latreille refers to the above arrangement in a note, `Règne Animal,' v. p. 178, but has altered it to the following plan:

  1. “Le prothorax beaucoup plus court que le mésothorax; le corps et les pattes longs, linéaires.
    1. Aptères.
      1. Antennes très courtes, grenues, en forme d'alène.
        Bacillus.
      2. Antennes notablement plus longues que la tête et en forme de soie.
        Bacteria.
    2. Des élytres et des ailes du moins dans l'un des sexes.
      1. Points d'yeux lisses.
        1. Pieds également espacés.
          Cladoxerus.
        2. Les quatre derniers pieds plus rapprochés.
          Cyphocrana.
      2. Yeux lisses.
        Phasma.
  2. Corps plus on moins ovalaire ou oblong, aplati, mais point linéaire.
    1. Prothorax plus court que le mésothorax; des élytres et des ailes aux deux sexes.
      Prisopus.
    2. Prothorax presque aussi long que le mésothorax; femelles privées d'ailes; mâles avec des élytres très courtes.
      Phyllium.”

M. Serville has since remodelled the arrangement mentioned as given by him in the `Encyclopédie Méthodique'; which alteration he published in the `Annales des Sciences Naturelles' for January 1831. It differs but little from the former, except in the introduction of a new genus, Xerosoma, and in the transposition of his sections of the winged and unocellated forms. In a notice of my monograph of the Australian species of Phasma, inserted in the `Entomological Magazine' for October 1833, the reviewer has proposed, on what appear to me very insufficient grounds, to subdivide two decided families (those of which Mantis and Phasma may be regarded as the types,) into four; which, with the addition of a fifth for the reception of Mantispa, are made to compose the Stirps (Tribe) Phasmina of MacLeay. The difference between Mantidæ and Empusidæ, which is made to depend solely on the prolongation or non-prolongation of the head in the shape of a horn, (a character that can have no appreciable influence on the habits of the two groups, which are known to be identical,) is too trivial, as well as too artificial, to form the basis of a
Page 5
natural classification; and a long and attentive study of the insects which constitute the Phasmidæ and Phyllidæ of the anonymous author has shown me too clearly the gradual nature of the transition between the linear and frequently apterous body of the former, and the dilated and winged body of the latter, to allow of my adopting those characters as the means of separating into distinct families insects whose habits are the same. I continue, therefore, to regard the Spectres of Stoll as a natural group, and include both Phasma and Phyllium under the family name of Phasmidæ, which I have adopted from that excellent entomologist, Mr. Kirby. In this family I have, as will hereafter be seen, many new generic subdivisions to propose, in addition to those which have been already instituted by M. Serville, which I can, however, only in part adopt.

I shall now proceed to offer some account of the structure of these insects in their several parts, and of the principal modifications to which they are subject in the different genera which I have found it expedient either to receive or to establish.

The antennæ of Phasmidæ are generally inserted near the eyes, and have their first and second joints compressed and broader than the rest, and the basal and apical shorter than the intermediate joints. These organs are sometimes setaceous and elongate, and sometimes short and submoniliform, varying in the number of joints from thirty down to twelve. They also vary much in length, even in the same subdivision, as well as in the sexes, being sometimes much longer than the body, and in other cases not exceeding the mesothorax in length.

The eyes are always large, prominent, and placed at the anterior angles of the head; and some of the Pterophasmata possess in addition three distinct stemmata*,
* These organs were first mentioned by Stoll, in his characters for the fifth division of his genus Spectrum: “5. Trois petits yeux lisses, disposes en triangle entre ceux à réseau,” - leaving it to be inferred that all the species of that division possessed them. Fabricius, on the other hand, takes not the slightest notice of them either in his generic or specific characters; and Latreille, in his `Genera Crustaceorum,' &c. iii. p. 87, says of them, “Ocellis nullis aut vix discernendis.” The Rev. Mr. Kirby remarks, that “Latreille speaks of Phasma as having no stemmata; but it seems that he examined only the apterous ones, all the winged individuals, at least so far as I have examined them, having three very visible ones.” It is evident from this sentence, that Mr. Kirby must himself have by chance examined those species only which do possess stemmata; for many, even among the winged species, are destitute of these organs. He remarks in continuation, that “it may, I think, be laid down as a rule, that the larvæ and pupæ of Orthoptera have not these organs;” and certainly the rule may be applied to this family with great propriety. The use of them, Mr. Kirby tells us, “is probably for assisting them in flying;” but as many species that are destitute of stemmata are provided with large wings, equally with those which possess these organs, it must be regarded as doubtful whether they exist for that purpose or not. The Apterous species unquestionably do not possess them in the slightest degree.

MM. Lepelletier and Serville have laid great stress on these organs as furnishing sectional characters; they mention them at the bead of each genus of the winged division, and have formed two great sections, viz. those with distinct, and those with indistinct stemmata. They are far, however, from supplying tangible characters; for even the restricted genus Phasma, which is placed in the first section, contains species with, and others without these organs; I have therefore not noticed them in my short descriptions.

or ocelli, placed triangularly between them.

The head is sometimes quadrate, flat, or convex, or occasionally much gibbose; sometimes short and pyramidical, horned, or spined.

The mandibles are large, thick, somewhat rounded, with an acute, dentate, black margin, somewhat in the shape of a horseshoe.

The palpi are unequal, depressed, and hairy. The maxillary palpi are five-jointed, with the two basal joints the smallest; the third and fourth rather longer, and nearly equal; and the fifth rather longer, broad, obliquely truncate in some, and in others sub-ovate and acute. The labial palpi are three-jointed, with the first joint very small, and the second and last nearly equal; they are always similar in form to the former.

The maxilla is membranaceous, with the apex corneous, tridentate, and black.

The labium is transverse, bilobed, and membranaceous.

The thorax is subject to great variation of form: in some it is long and cylindrical; in others short, flat, and quadrate. Its length also varies considerably; for in the Pterophasmata it is always shorter than the abdomen, while in the Apterophasmata it is in some species as long as, or even longer than that organ, and very distinctly divided into three segments. Of these, the first, or prothorax, is gene rally shorter, but in one species it is longer than the mesothorax: it is generally subquadrate, sometimes armed with acute spines, and mostly convex above and flat beneath. The second, or mesothorax, is in most cases long and cylindrical, but in some as short as, or even shorter than the metathorax, and subquadrate; it is also sometimes armed with spines, which, according to Lichtenstein, furnish a sexual difference, the male being more strongly spined than the female in some cases this remark applies, but I am not inclined to consider it as a good substantial rule. The third, or metathorax, is not, in the Pterophasmata, easily distinguished, being generally short and quadrate, and partly hidden by the wings; but it is always broader than the others in the Apterophasmata, on the contrary, it is generally as long as the former segments, although sometimes it is rather shorter.

The wing-coverts, or tegmina, are membranaceous and opake; they vary much in length, and are rather shorter in the male than in the female. In the former sex, they are sometimes armed in the centre with an elevated ridge, and sometimes with a blunt or acute spine, while the females have the tegmina rather broad, longer and rounder at the tip, without armature in their centre. In the
Page 7
subapterous imago females, these organs are always larger than the rudimental wings; and on the other hand, there are species which possess only rudimental tegmina, though they are furnished with ample wings.

The wings are transparent, with a broad anterior membranaceous margin, generally termed the costa or costal area, which is opake, and when closed, entirely covers the transparent portion. The organs vary much in length, sometimes nearly covering the abdomen; in others (in the female) they are rudimental; and sometimes they are entirely wanting: their shape varies much, not merely in the species, but even in the sexes, for they are generally shorter and broader in the female than in the male.

The abdomen also varies considerably in form. In some it is long and cylindrical; in others, filiform: in some it is broad, convex above, and flat beneath; in others, perfectly flat and membranaceous; and others have only certain segments dilated above or laterally: it is in general composed of ten segments. The apex is variously modified, according to the species; and is generally curved upwards in the male. Some of the Pterophasmata have three, and others only two long or short leaflets at the extremity of the abdomen; and sometimes the last segment, or hypopygium, of the female is furnished with an elongate and cymbiform oviduct. In other species, the apex is gibbose; and in some of the Apterophasmata it is similar in form to the head of a spear. It is often armed with a pair of forceps (which is probably found more prominent in the males of both subfamilies), situated beneath the last upper segment or podex, and supposed to assist in copulation: in some males the last-mentioned organs are bifid. In one or two species spiracles are visible, placed one on each side, at the base of the segments.

The legs are similarly formed (adapted for running), but differ much in form and length in different species: sometimes the fore legs are the longest; sometimes the intermediate pair are much shorter than the others; sometimes the posterior pair are the shortest. The fore legs are seated so near the head as to require an excavation near the base for their reception, and are said to be directed straight forward, when at rest, as if to protect the antennæ from injury. In some these organs are spined, or more or less dentated; in others, more or less perfoliate and membranaceous.

The tarsi are always composed of five unequal joints, the first of which is always the longest, the others gradually decreasing in size: the fifth is large, pyriform, and armed with two long, compressed, hooked, (sometimes bifid,) acute claws, between which is placed a very prominent plantula or cushion. Some species have an elevated ridge along the upper surface of their tarsi.

It may be observed as a general rule, that the males of these insects are much shorter and more filiform than the females, the former in some cases measuring only half the length of the latter sex. The means of distinguishing between their different stages of
Page 8
larva, pupa, and imago also require some notice; and the following rules may serve the purpose of effecting this distinction.

The larvæ (or, as Latreille terms them, Podophanera,) are always apterous, much smaller than either pupa or imago, thicker throughout in proportion, of a much lighter colour, and rather brittle in their appearance.

The pupæ (or Pterophanera) of the Pterophasmata are much more readily known by the appearance of rudimental wings, and by having their tegmina always smaller than the future wings. The latter are invariably spotted, and the nervures are very thick when arrived at this state, the insects have attained their full size.

The imago (or Holophanera) of the Pterophasmata is distinguished by the expansion of the wings, which are of various lengths, from hardly covering the first segment of the abdomen, to its entire concealment. Some of the females are subapterous even in this stage, in which case the tegmina are always larger than the rudimental wings.

The apterous species become in this state rather slenderer, and their outer surface is firmer and more durable in texture than in their former stages.

The extraordinary forms of these insects, rendered still more remarkable by their large size, have given rise to various appellations derived from a supposed resemblance to unearthly beings, such as the devil's horse, spectre, phantom, &c.; while, on the other hand, others are denominated walking leaves, walking sticks, walking straws, and animated sticks, from the striking similarity which they bear to such vegetable substances. “To such perfection, indeed,” say Messrs. Kirby and Spence, “has Nature in them carried her mimetic art, that you would declare, upon beholding some insects, that they had robbed the trees of their leaves to form for themselves artificial wings, so exactly do they resemble them in their form, substance, and vascular structure; some representing green leaves, and others those that are dry and withered: nay, sometimes this mimicry is so exquisite, that you would mistake the whole insect for a portion of the branching spray of a tree.”

“I have one from Brazil,” says one of the same authors, “eight inches long, that, unless it was seen to move, could scarcely be conceived to be anything else than a small branch with its spray, the legs as well as the head having their little snags and knobs, so that no imitation can be more perfect.”

Not only, indeed, are the perfect insects similar to portions of vegetables, but even their eggs bear a great resemblance to seeds and their envelopes, insomuch that some of them might at first sight be mistaken for the deeply-ribbed fruits of various umbelliferous plants.

Mr. Parkinson has given the following account of the abdomen and eggs of Heteropteryx dilatata “The former,” he says, “is terminated by a kind of boat-shaped organ, the keel of which possesses a
Page 9
considerable space beneath the abdomen, so that fewer segments appear on that part than above. The concavity of this is covered above by a terminal scale and bifid process, constituting the tip of the abdomen on the upper part. On raising this valve, an ovum, nearly of the size of a pea, but of a more lengthened form, was discovered lying in the cavity beneath; and on inspecting further into the cavity of the abdomen, a great many more ova, exactly similar, were found, to the number of five- or six-and-twenty, some still remaining in the upper part. These eggs are of a slightly oblong shape, but flattened at one end: they are of a brown colour, and marked over with numerous impressed points; and have on one side a mark or double-waved line, so disposed as to represent a kind of cross, as if carved on the surface. The flattened end is surrounded by a small rim or ledge, and seems to be the part which opens at the exclusion of the larva, since it readily separates from the rest.”

Dr. Müller has also described the ovaries of one of the species, Bacteria arumatia, in a paper, which points out a connexion between the dorsal vessel and the ovaries, published in the `Nova Acta Physico-Medica Academiæ Cæsareæ Leopoldino-Carolinæ Naturæ Curiosorum,' tom. xii. pars 2., 1825; which paper was reviewed in the `Zoological Journal,' iii. p. 257, from whence I have copied the following account

“The ovaries, which occupy the whole length of the abdomen, consist of about fifty conical tubes, the bases of which communicate with the oviduct of each side. The tubes are from four to five lines in length, and contain each from eight to fourteen eggs in various stages of development, together with certain other parts, which appear to furnish the materials for their growth. The eggs decrease in size towards the apices of the tubes, which pass insensibly into a very fine elastic filament. These filaments, of equal breadth throughout, are inserted, at their opposite extremity, into the dorsal vessel, with the inner lining of which they are unquestionably continuous. They contain a granular, medullary, irregular, and frequently interrupted substance, which is continued from the interior of the dorsal vessel, and lies in immediate contact with the contents of the tubes. When these filaments,” observes the author, “ have once been seen, the idea of a mistake can no longer exist. I have shown them to many; the connexion is so frequent, so obvious, and so circumscribed, that there is no occasion to employ a microscope to be convinced of its existence. I have never heard a second opinion on the subject. The connecting filament, however, does not merely unite the dorsal vessel with the apex of the ovarian tube; it passes into the interior of the latter, and lines its internal surface in immediate contact with its contents, and expanding as it advances, terminates near the union of the tube with the oviduct, in a free edge. The portion which is thus enveloped by the tube is capable of being separated from it; it alone contains
Page 10
the eggs and their rudiments, the filamental portion which is exterior to the tube, being filled with the irregular medullary substance derived from the contents of the dorsal vessel. All these facts are well illustrated in the plates which accompany the Memoir.”

The habits of the Phasmidæ are at present little known; but Stoll informs us that they differ much from Mantidæ “par leur manière de vivre et par leur économie, ou qu'ils se nourrissent d'herbes, de plantes, et de feuilles d'arbres, et deposent leurs oeufs en terre tout comme les Sauterelles.” Mr. Allan Cunningham, the botanist, who has had occasion to observe several of the Australian species in their native haunts, has informed me, “that the reason why they are so rarely met with, is owing to their solitary and sedate habits, being found always single, or only two in company, crawling slowly up the underwood, shrubs, &c., on which they seem to pass their existence in the hot summer months, feeding on the young glutinous or gum my trees.” He states, also, that they occasionally disappear, perhaps for two or three years together.

Mr. Say gives the following account of an apterous species, which in this Synopsis is called Anisomorpha buprestoides: “On a journey to Florida with Mr. Maclure, I obtained a female, which was crawling up the body of an orange tree on Cumberland Island, Georgia. The male I had not seen until the recent return of Mr. Peale from that country, who brought many individuals of both sexes. He observed them in plenty in the southern part of that region: they were generally in pairs on the Palmetto, lying close to the rib of the leaf. Mr. P. remarked, that when taken they discharged a milky fluid from two pores of the thorax, diffusing a strong odour, in a measure like that of the common Gnaphalium, or Life-everlasting; and as this plant was growing near the place where they occurred, he supposed that it constituted at least part of their food. They vary much in colour, but it is believed that the two dorsal yellow lines are never wanting.”

I was informed by Dr. Harlan (during his stay in London), that the female of an American species had actually been seen to eat off the head of her unfortunate companion, while in the excitement of their mutual amours.

The following is a translation of the account of the habits of Bacteria bicornis, given by the late Rev. Lansdown Guilding, in the `Transactions of the Linnean Society': “ It is extremely common in the brushes of Equinoctial America, and the neighbouring islands, and deludes its enemies by its resemblance to a dead stick. It devours the leaves with avidity during the night; walks with a very vacillating motion; applies its anterior feet to its head when in repose, and thus defends its slender antennæ. It is tenacious of life. Its juices are green or pale.

“The imago occurs throughout the year, copulating in the months of May and June. The female lays 22 eggs from September to November, which remain quiescent from 79 to 100 days, the larva
Page 11
being excluded between the months of March and August. The larva, when first excluded from the egg, is pale, with banded legs; when it has thrown off its first exuviæ it grows with great rapidity, until the horns make their appearance, and the body becomes red. If it loses a leg by violence, this is reproduced, but of a smaller size, on the next change of skin.

“The pupa scarcely differs from the imago.

“The egg is solid, clouded with flesh-colour and reddish, with scattered excavated dots, and a lateral chain-like spot, brown in the middle; its operculum is honeycombed and yellowish.

“The eggs of our Phasma are retained long in the oviduct, until they become indurated; and although those of Mantis are laid with caution, these are rejected without any peculiar care.”

The geographical extension of these insects is bounded by the parallel of fifty degrees on each side of the equinoctial line; and the following plan will show their further distribution among the great physical divisions of the surface of the earth.

Doubtful10

Only two small apterous species have yet been with certainty detected in Africa*;
* I have only myself had the good fortune to meet with two small species from Africa, although I think there is good reason for believing these insects to be farfrom uncommon in that continent. Stoll, however, mentions that the Platycrana viridana is found in Africa, as well as in India and South America; an extent of geographical range which I cannot conceive to be at all probable. In my Synopsis I have marked its habitat as India. Edwards, also, has figured a species said to be from the Cape of Good Hope; but as the figure is very bad in itself, and represents the insect in an immature state (being a pupa), I cannot refer it to any species mentioned in the Synopsis, or determine with any degree of certainty whether it constitutes a new species, as is most probably the case.
and it may deserve notice, that the last ten degrees from the line contain only apterous species, while both winged and wingless are scattered over the remaining forty. They also become more numerous, and of a larger size, as we approach the equator on either side. There exist great analogies of form between the Indian and South American species, examples of which will be found among the true Phasmata and the Cladoxeri.

I have found, on examining various specimens of the same species in different collections, that they vary much in colour; a circumstance which is greatly owing to the oily nature of their bodies, and to the neglect of the collector, at the, time of taking the specimen, in not making use of the precaution, which is commonly adopted
Page 12
in this country, in preserving the Libellulidæ, by means of which the colours of the insects would be in a great degree preserved. This operation (which may not be generally known) consists in opening a longitudinal slit on the under surface of the abdomen, and taking out the entrails; the cavity is then stuffed with soft cotton, and the insect is allowed to dry in an airy situation. If these precautions have not been had recourse to in preserving the specimens, it will be found that the insects, which, when living, were of a bright green, frequently change to diffe rent shades of brown; and I have even observed the abdomen in some specimens to become black. In a dark blackish brown species, I have seen that organ converted into a rust colour. A milky fluid also exudes from the thorax, when the pin is passed through it, which is capable of staining the adjacent parts yellow and other colours. These facts are stated for the purpose of showing that some allowance must be made on this score, if my short descriptions of the shades and colours here given do not in all cases exactly coincide with the individual specimens which may fall under the notice of other entomologists.

It will be perceived that, in forming my table of divisions, I have, like other authors who have written on this group, used only external characters. The cibarian organs of species belonging to distinct divisions bear so great a similarity to each other, that it is impossible to make use of them as divisional characters. Like Fabricius, I have commenced with the apterous species, considering them, as it were, the most imperfect; and from these, by means of a species which possesses wings only, equal in length to the abdomen, we are enabled to proceed to the more perfect ones, which are provided with both tegmina and wings.

* As the specimens and figures which I have examined, vary much in size and outline, I am induced to consider that there probably exist two species, which have hitherto been confounded under one denomination.

Thus, the Ceylonese specimen above referred to and also the figure in Dumeril's `Considérations' are probably distinct, on account of their being shorter and much broader in proportion than the figures in Stoll and Donovan and several specimens, which I have examined, which are longer and not so broad by several lines; as may be seen by referring to the measurements given above.

DOUBTFUL SPECIES, &c.

Phasma acicularis, Stoll, Spec., pl. 25, f. 97, belongs to Mantis.

Phasma vermicularis, Stoll, pl. 23, f. 88, probably belongs to the subgenus Anisomorpha.

Phasma Nympha, Stoll, pl. 10, f. 39.

Mantis labiata, Gmelin, is supposed by Lichtenstein to belong to this family.

Phasma baculus, Latr., Hist. Nat. des Crust. et des Ins., xii, p. 104, pl. 94, f. 2.
Spectrum baculus, Lam. Anim. sans Vert., iv, 254.
"Corpore cinerascente, tuberculato, aptero; pedibus abgulatis. Antilles, Il a les antennes courtes; seraitce une femelle."
The figure referred to above represents a pupa of a true Mantis.

Cladoxerus roseipennis, Guer. Iconog. Ins., pl. 53, f. 5, known only by the dissection of the Trophi, as given by M. Guerin.


Figures will be found in the following works, which are so incorrect that it is impossible to refer them to any of the species mentioned in this list.

Renard, Poissons des Moluccques. fol. 1754.

Petiver, Gazophytacium Naturæ et Artis.

Edwards, Birds, pl. 288, f. 4. Walking stick from the Cape of Good Hope. A pupa of a species, probably belonging to Platycrana.
