INTRODUCTION.

THE enumeration of the species of the five Families of Orthoptera here dealt with

having already extended to 458 pages, with twenty-one Plates, it has been decided to

treat the two remaining families, the Acridiide and the Phasmide, in a separate

volume. All the arrangements for the publication of the present volume have been

entirely under the control of Dr. Henri de Saussure, of Geneva, who, on account of

his failing eyesight, has been obliged to give up the remainder of the work.

The Forficulide have been worked out by Count de Bormans alone.

The Blattide and Mantide by Dr. Henri de Sanssure, in collaboration with Dr. Leo

Zehntner.

The Gryllide by Dr. H. de Saussure alone.

The Locustide by Dr. H. de Saussure, with the assistance of M. Alphonse Pictet.

The Introductory remarks and all the general dissertations on the Blattide, Mantide,

Gryllide, and Locustide have been contributed entirely by Dr. H. de Saussure. In

these Families the author has also described, noticed, or figured various allied North-

American or Tropical South-American species for comparison, as it is very probable

that some of these will eventually be found to inhabit the region under investigation.

These species are throughout the work included in square brackets, though for

convenience they are numbered consecutively with the others in the text.

The following is the total number of species enumerated from Central America :—

Forficulide, forty-one, with eight new; Blattide, 156, with sixty new; Mantide,

sixty-one, with thirty-three new ; Gryllide, 102, with forty-three new; Locustide, 273,

with eighty new. The number of species for the five Families being 633, with

224 new.

The Acridiide have been undertaken by Professor Lawrence Bruner, of Lincoln,

Nebraska, and we hope to commence the publication of Volume II. immediately.

long et méme plus long que large. Serville, au contraire, le dit: étroit, transversal.

Cette contradiction peut s’expliquer ainsi: Serville a fondé son genre Diplatys sur un

seul exemplaire (male puisque son abdomen était presque cylindrique), en assez

mauvais état pour qu'il fit difficile d’en reconnaitre le sexe. Or, le sexe se reconnait

sans erreur possible, chez les Dermaptéres, par le nombre des segments abdominaux

apparents, comptés d’abord en dessus, puis en dessous. I] est donc évident que, chez

Yindividu examiné par Serville, les segments abdominaux étaient en partie détruits,

mutilés, peut-étre recollés en sens inverse, et que l’auteur a été trompé par rapport a la

forme réelle du pénultiéme segment ventral.

Le type de Diplatys macracephala n’existe plus, mais heureusement la figure donnée

par Palisot de Beauvois est parfaitement reconnaissable et concorde absolument avec

plusieurs exemplaires intacts de cette espéce (venant de Benin et du Congo) d’aprés

lesquels j’établis cette nouvelle description du genre Diplatys.

1. Diplatys jansoni. (Tab. I. figg. 1, ¢; 2, 2.)

Cylindrogaster Jansoni, Kirby, Journ. Linn. Soc., Zool. xxiii. p. 507 (1891)".

Hab. Guatémata, Las Mercedes, Panzos (Champion); Nicaragua, Chontales 1 (Janson) ;

Panama, Bugaba (Champion). [3 2.]

L’espéce que j’ai sous les yeux est évidemment celle décrite par Mr. Kirby, car elle

correspond exactement 4 la description de cet auteur; de plus, parmi les nombreux

exemplaires en question, quelques-uns portent l’étiquette: “Chontales, Nicaragua

(Janson).” Or, tous ces exemplaires ont, aux 2° et 3° segments de l’abdomen, des plis — |

tuberculiformes bien distincts; tous leurs autres caractéres, du reste, les rangent dans —

le genre Diplatys redécrit ci-dessus. Mr. Kirby n’a décrit que le male; la femelle ne

différe que par les caractéres génériques.

2. Diplatys severa, sp.n. (Tab. I. fig. 3, 3.)

3. Longit. corp. 7°50 millim. ; forcip. 1:25 millim.

Caput nigrum, ut in D. jansoni constructum ; antennis 15-articulatis, testaceis. Pronotum nigrum, limbo tenui

semicirculari pallido marginatum. Elytra nigra, viridi-zeneo obscuro velutino splendore micantia, versus

ad quartam partem anticam fascia albido-flava transversa ornata. Als albew, apice nigro. Elytra aleeque

albo-setulosa. Pedes fusci, genubus fusco-testaceis. Abdomen totum nigrum ; forceps pallide testacea.

Hab. Panama, Volcan de Chiriqui 2500! (Champion).

Malgré les différences de taille et de coloration, cette espéce n’est, peut-étre, qu’une

variété de la précédente ; je ne puis résoudre cette question, n’ayant vu qu'un exemplaire

de D. severa.

ECHINOPSALIS, gen. nov.

Corpus modice convexum ; pronoto, elytris, alarum squamis, interdum abdomine toto, setis brevibus, rigidis,

presertim ad latera hirtis. Caput sat convexum, que latum ac longum; antenne plus 22-articulate :

art. 1° parum longo, crasso, obconico; 2° exiguo, cylindrico; 3° primi longitudinem squante, sed

ECHINOPSALIS.—PYRAGRA. 3

angustiore; 4°-8° globulosis, secundo parum longioribus; reliquis obconicis, sensim crescentibus, sed

semper parvis et vix angustioribus. Pronotum capiti longitudine equale, latius quam longius, fere

quadratum, angulis preesertim posticis rotundatis. Elytra lateribus rectis; alarumque squame perfectz.

Pedes breves, femoribus crassis, tibiis tarsisque gracilibus; tarsorum articulo 1° tertii longitudinem

eequante, sed illo crassiore, 2° brevissimo, cylindrico, apice leviter bifida. Abdomen: 9 lateribus fere

parallelis; ultimo dorsali segmento subrectangulari, latiore quam longiore; penultimo ventrali segmento

multo latiore quam longiore, dimidia parte basali obtuse triangulari, apice ovato-producto; ultimi segmenti

medio longitudinaliter fissi fere dimidia parte patente. Forcipis crura subcontigua, sat brevia, crassa,

triquetra, subrecta, apice ipso curvato, ut in genere Psalz constructa.

(Mares ignoti.)

Ce genre nouveau, dont je n’ai vu que deux femelles, une du Nicaragua, l’autre du

Pérou, est tout voisin du genre Pyragra; il s’en distingue par: la téte plus bombée et

plus étroite; le pronotum non rétréci antérieurement, plus court, moins arrondi; les

pattes plus courtes, sans pelotes visibles entre les griffes, et la forme de la pince.

Il différe du genre Echinosoma par la forme de tout abdomen, du dernier segment

dorsal, du pénultiéme segment ventral, et de la pince.

En résumé, les insectes de ce genre ont la moitié antérieure du corps—téte, pronotum,

élytres, ailes et pattes—du genre Hchinosoma, et la moitié postérieure—abdomen et

pince—du genre Psalis.

(Nous nous sommes assuré, il est presque inutile de le dire, que nos exemplaires ne

sont point artificiels, c'est 4 dire dus 4 la réunion maladroite de deux moitiés d’insectes |

divers. Ce cas ne se présente que trop fréquemment lorsque des amateurs inexpéri-

mentés veulent réparer les ruptures causées par les chocs dans de longs voyages.)

1. Echinopsalis guttata, sp. n. (Tab. I. fig. 4, 2.)

9. Caput nigrum, clypeo testaceo; antenne saltem 22-articulate, fusce, art. 2° et 3° testaceis exceptis.

Pronotum nigro-fuscum, lateribus et parte postica late albo-flavo marginatis. lytra nigro-fusca, macula

magna triangulari albo-flava longitudinaliter a basi usque ad medium ornata. Alarum media pars interna

fusco-nigra, media pars externa flava. Femorum pars media basalis fusco-nigra, pars apicalis albo-testacea ;

tibiee tarsique albo-testacei. Caput, pronotum, elytra, ale, pedesque pilis fuscis hirsuta. Abdomen fere

glabrum, castaneum, ultimo dorsali segmento fere quadrato. Forcipis crura ut in genere Psalz formata,

ineequalia (dextro longiore), castanea, robusta, margine interno denticulato.

genre. I] faudrait pour fixer sa position avoir plus d’un exemplaire sous les yeux.

SPHINGOLABIS.

Sphingolabis, de Bormans, Ann. Soc. Ent. Belg. xxvii., Tableau Syn. des genres des Forficulaires,

no. 25 (1883).

La diagnose du tableau synoptique cité ci-dessus doit étre ainsi rectifiée et complétée:—

Forcipis crura in g basi remota, plerumque subteretia ; elytra semper perfecte explicata, ale explicate vel

deficientes. Omnibus aliis notis charactericis cum genere Forficula hoc genus congruit. Femine omnino

speciebus Forficularum similes.

Lorsque j’ai établi ce genre, je rangeais (bien qu’d regret), d’aprés l’autorité de

Herr Brunner de Wattenwyl, les Forficula: albipennis, Meg., et arachidis, Yersin, dans

le genre Chelidura, Latr.; mais Y’examen de diverses espéces exotiques: teniata,

Dohrn, californica, Dohrn, etc., m’a montré qu’on ne pouvait séparer génériquement

ces derniéres des F, albipennis, etc. Ila donc fallu créer au moins un genre nouveau

(deux, en admettant le genre Apterygida, Westwood, mais tous les auteurs ont supprimé

ce dernier, sauf Mr. Kirby dans son ouvrage récent: 1891).

12 _ ORTHOPTERA.

Ce genre Sphingolabis répond au 1 groupe des Forficula de M. Dohrn: Pinces du

male écartées 4 la base, cylindriques, assez uniformément courbées en dedans jusqu’a

leur pointe. (Cependant la 8. furcifera, de Borm., a les branches de la pince aplaties,

quoique bien écartées 4 la base.)

La caractéristique de ce genre a le trés grand défaut de s’appliquer aux males seuls;

il est impossible de savoir si une femelle regue séparément est une Forjicula ou une

Sphingolabis.

BLATTIDA. 18

Suborder ORTHOPTERA GENUINA *

Fam, BLATTIDE jf.

For the classification of this family we have followed in a general way the excellent

work of Herr Brunner von Wattenwyl, ‘Nouveau Systéme des Blattaires,’ and his

‘Revision du Systéme des Orthoptéres,’ in which he has introduced some modifications

of his former system. Nevertheless, we have been obliged to give here a Conspectus

of the tribes and genera, as it was necessary to introduce several modifications in the

method of the author, particularly in regard to the American Blattide and to the

disposition of the new genera.

Many species are very vagrant, finding their way into habitations, storehouses,

merchandise, and ships, and are thus readily transported from one country to another.

Some are quite cosmopolitan, and this has induced us to enumerate a number of

species inhabiting the Antilles and South America which may possibly be found in

Central America; others we have mentioned to avoid confusion with allied species of

the central parts of America; the names of these are placed within square brackets.

_ Of the same colour as Theganopteryx fallax, but very different in the neuration of its

wings. TZ. intermedia might, at first sight, be referred to the genus Blatta, owing to the

rudimentary triangular reflexed field of the wings; but the style of venation is more

that of Theganopteryx, and the femora have only a few spines, as in the Anaplectine. |

Of the same facies as A. azteca, A. replicata, A. grandipennis, A. decipiens, A. albo-

marginata, and A. fallax, but distinct from all these (A. azteca excepted) on account of

the wings being one half shorter and the elytra narrower. Smaller than A. decipiens,

with the elytra more rounded at the tip and not reticulated, and the wings with shorter

appendicular field. A little larger than A. replicata and A. grandipennis, with very

differently formed wings (comp. synopsis specierum II. 2, anted, p. 21). Distinguished

from A. albomarginata by the shorter elytra, infuscated wings with shorter appendicular

field, &c. It is quite similar to A. fallax, only the elytra are a little shorter, not

longer than the abdomen, and the wings one half smaller, a little more infuscated, with

the appendicular field a little shorter and the longitudinal venula of the end of the

medio-discoidal area shorter and oblique. . A. parvipennis is remarkable for its small

hind wings—when extended reaching scarcely to the end of the abdomen—being

scarcely longer than the elytra. It is the only known species possessing this character.

This species is closely allied to A. fallax; but in A. fallax the elytra are a little

more rounded at the tip, reticulated only at the end, and the appendicular field (¢ ) of

the wings is much shorter, not so long as broad, while the contrary is the case in

A. decipiens (@). Nevertheless, A. decipiens and A. fallax may belong to the same

species. Also very similar to A. lateralis (Burm.), Brunner, of South America; but

the appendicular field of the wing is much wider and more rounded in A. decipiens.

Blattites, Saussure, Miss. Scient. Mex., Orthopt. p. 20.

The species of this Tribe present two different types in the armature of their anterior

femora. The anterior inferior edge of these femora always bears two long apical spines ;

but the edge itself is armed as follows :—

Type 1 (Tab. VI. fig. 17). The basal half with 3-6 long spines distant from each

other, and the apical part with numerous very small setiform spinule (type Platamodes,

Scudd., Stal). |

Type 2. The entire edge armed with distinct spines, which are smaller in the apical

half than the basal spines, and decrease in length towards the end.

Scudder has proposed the genus Platamodes for a species of Ischnoptera belonging

to the first type; and Stal has divided nearly the whole Tribe into two genera based

upon the two types here indicated. This system of classification cannot, however, be

maintained, the two types reappearing in most of the natural genera; so that if it was

' adopted we should have to make twice as many genera.

Stal has also proposed a genus Liosilpha to receive the species of the second type which

have the supra-anal plate () a little emarginated (comp. Tab. IV. fig. 21); but this

character is also found in a number of species of the first type, so that if we follow

him we should have to still further subdivide the genera. Neither Scudder nor St&l

would have taken the above-mentioned characters as generic if they had examined a

greater number of species. Thus, we have preserved the excellent classification given

by Brunner de Wattenwyl in his ‘Systéme des Blattaires,’ to the exclusion of the

divisions proposed by Stél, utilizing the characters of the two types only to form

sections of the genera.

The markings of the pronotum are variable, the three colours being more or less

extended one over the other. In a general way, the pronotum may be described as

yellow, with a large trapezoidal reddish picture on the disc, this being divided by a

black band, which is more or less extended anteriorly and more or less dilated poste-

riorly, so as to cover sometimes the greatest part of the hind margin.

This species is very closely allied to B. brunneriana. It has the pronotum somewhat

larger and the wings not infuscated. In B. brunneriana the first nine of the vene

costales are much more thickened and clavated, being terminated by elongated brown

thickenings. B. azteca also much resembles B. alaris; but the wings are not reticulated

with brown colour, and the vene costales are more thickened. The second branch of

the vena mediastina forms three vene costales, and the lamina infra-genitalis is much

produced beyond the last ventral segment.

This insect much resembles B. nahua, Sauss. It is a little smaller; the wings are

not so regularly reticulated; the eyes are more distant, not convergent above; and the

cerci are shorter (not moniliform, as in B. nahua, 3). The lamina supra-analis and

the lamina infra-genitalis are very differently formed in the two species. B. chichimeca

may prove to be the male of &. zapoteca, Sauss. (t); but it does not possess the same

brown picturing of the body, and the elytra are less fulvous, more transparent.

I first described this species under the name Blatta venosa (loc. cit.). Subsequently

(Miss. Scient. Mex., Orthopt. p. 44.3) I united it with B. angustata, Latr., from

Colombia, Guiana, and Peru; but it is perhaps distinct from that species, the ulnar

vein of the wing having only two branches, and the apical margin being not or only

very slightly infuscated, while in &. angustata the wings are infuscated on the apical

margin and have three ulnar branches. It is difficult to decide whether B. venosa and

B. angustata are to be considered as distinct, or as mere varieties of one and the same

species (Saussure).

Many specimens were sent by Mr. Smith from Tabasco.

transition to that anomaly in some species of Blatta, in which the end of the lamina

supra-analis is notched in an irregular way, its angles forming two small unequal

processes arched one against the other (B. adspersicollis, Stal).

This Tribe forms a sort of transition from the Blattine to the Periplanetine on

account of the shape of the anal plate and the long cerci. The elytra and wings have

quite the neuration of the Periplanetine; but the last ventral segment is flat as in

Blattine, not compressed and sulcate as in Periplanetine. The presence of narrow,

tongue-like appendices on the margins of the meso- and metanotum shows a further

affinity with the Periplanetine. The Tribe Nyctoborine is peculiar to the hot parts

of America. It includes only two genera: Nyctobora, in which the claws are

furnished with an arolium, and Megalobatta, which is destitute of an arolium between

the claws.

MEGALOBLATTA. 57

This genus is a magnificent Central-American type, and is of great interest on account

of its affinities.

It resembles the Periplanetine, especially the genus Periplaneta, in the produced

bilobed supra-anal plate and in the very long cerci. In the shape of the last segments

of the abdomen, which are not acute at their angles, the short spines to the femora,

and the black-violaceous colour of the pronotum and elytra, Megaloblatta approaches

Deropeltis, the colour being quite typical of that genus and foreign to the other American

Blattide. In other respects Megaloblatta imitates in a very remarkable manner the

larger species of the genus blabera: in its gigantic size, the approximated eyes, the

very large and wide elytra having a very broad marginal field, and, what is very striking

indeed, in the claws being destitute of an arolium—the latter character appearing here

as if for the sole purpose of imitating the Blaberine !

This mimicry is carried to such an extent that at first sight it 1s very easy to mistake

a Megaloblatta for a Blabera. ‘The resemblance, indeed, is continued even to the less

apparent characters, as the loss of the arolia and the arrangement and scarcity of the

spines of the femora. It is only by an examination of the characters of the abdomen

(unspined angles of the segments, long anal plate, very long cerci) that the real position

of Megaloblatia can be ascertained.

The specimen ( 3 ) described by H. Dohrn has the abdominal segments rufous, with

black margins, and the legs rufous, with the anterior femora armed with only one spine

—placed on the inner (anterior) margin. Nevertheless I believe our individual from

Guatemala belongs to the same species, the proportions being similar.

M. (Blabera) regina, Sauss. (from Brazil?), may be inseparable from M. rufipes,

Dohrn, to judge by its size.

MM. peruviana, Dohrn (= Blabera rufipennis, Walk.), from the Upper Amazons, seems

to be a smaller species, with more spined anterior femora, although this character is

somewhat variable.

This Tribe is equivalent to the Anaplectine, but its species are destitute of spines on

the femora; it has the same peculiar structure of the wings, 7. ¢. these organs have an

apical turned back field—either small and intercalated, or large and appendicular. In

the Plectopterine this character becomes even more strongly pronounced (Diploptera)

than in the Anaplectine. The resemblance of the two tribes is especially remarkable

in the genera Chorisoneura (corresponding to Ectobia) and Anaptycta (corresponding to

Anaplecta). The genus Plectoptera reproduces also with great similarity the wing of

an Anaplecta. | |

The name “Chorisoneuride” has recently been changed to “ Oxyhaloide” by

Brunner de Wattenwyl, this author having followed the suggestion of Stal in placing

Chorisoneura in his Tribe “ Ectobine,” next to Ectobia, owing to its external resem-

blance to that genus. The name ‘‘ Oxyhaloide,” formed from the generic term

Oxyhaloa, does not seem suitable, as Oryhaloa is the only genus in which the most

important character of the Tribe (appendicular field to the wings) is not expressed

(see below, p. 77). In consequence, we prefer to name this Tribe “ Plectopterine,”’

after the typical genus Plectoptera (comp. pp. 14, 15).

We do not adopt the views of Staland Brunner de Wattenwyl as regards the position

of Chorisoneura. We consider that the Anaplectine (Ectobine, Brunn. de W.) and

the Plectopterine form two parallel series, in each of which much the same kind of

types are repeated as follows :—

The names “Ectobide” and ‘*Chorisoneuride,” introduced by Brunner de Wattenwyl,

are very appropriate, being based on corresponding equivalent genera. Now, as the

name “Chorisoneurine ” has to be abandoned, it is convenient to replace it by the

of Ectobine). In this way the names of the two Tribes will be based on their most

typical and most perfectly corresponding genera.

Ozxyhaloa, Brunner de W. Syst. Blatt. p. 252; Saussure, Miss. Scient. Mex., Orthopt. p. 89.

This rather aberrant genus lacks the most important characters of the Tribe

Plectopterine—to wit, the wings do not possess an intercalated or appendicular field,

which, in rest, is turned back on the upperside. But this exception is more apparent

than real; in Oxyhaloa the intercalated triangular field is virtually present, but it

is confounded with the posterior field; and this is why the axillar nervure is arched,

enveloping the posterior margin of the anterior field *. The species of the Old World

are still more aberrant, as in these the posterior field does not envelop the hind margin

of the anterior one, and the axillar vein is straight.

In this genus the elytra have always two longitudinal nervures—the discoidal and

the median veins. The nervures of the discoidal field are either all longitudinal or

oblique ; in the latter case they form oblique branches of the median vein, but they are

ANAPTYCTA, Brunn. de W. »

Anaptycta, Brunner de Wattenwyl, P. Z. S. 1892, p. 202.

We place this genus in the Tribe Plectopterine, the femora not being spined; but

its facies is quite that of Anaplecta. ‘The wings are formed as in that genus, and have

an appendicular articulated apical field. The elytra are parted by a single longitudinal

nervure ; they are (as in the genus Ectobia, Br.) strongly pectinated by the numerous

costal and discoidal branches, and have a deep anal sulcus.

Hemipterota, Saussure, Societas Entomologica, 1893, p. 67.

Habitus generis Ceratinoptere. Caput vix prominulum. Pronotum majusculum, corneum, transverse para-

bolicum, antice leviter truncatum, convexiusculum ; marginibus leviter deflexis. Elytra cornea, polita,

abdominis longitudine vel breviora, sicut in genere Chorisoneura venosa, venis presertim subtilibus

remotis, per transluciditatem perspicuis. Pedes robustii— 9? 9. Lamina supra-analis trigonalis, apice

incisa. Cerci compressi, apice haud longe anguste producti, hebetati. Ultimum segmentum ventrale

apice minute compressum. Ale rudimentales.

The elytra are corneous, as in Areolaria, though they are very different in structure

in the two genera. In Areolaria the elytra are entirely occupied by very numerous,

contiguous, parallel, longitudinal veins, even in the marginal field, separated by lines

of punctures. In Hemipterota the elytra are not punctured, the veins are fine, only

distinct when viewed by transmitted light, remote from each other, and disposed as

in Chorisoneura. Hemipterota may be regarded as a somewhat degenerate form of

Chorisoneura with abbreviated elytra. Areolaria belongs to the type of Prosoplecta,

but with quite corneous elytra.

This genus is equivalent to Anaplecta, of the Anaplectine; but the elytra are convex

and comneous, very finely punctured, without apparent nervures, except when viewed by

transmitted light, and without anal sulcus. The wings have the appendicular field

larger than in Anaplecta (being half the length of the wing) ; the costal area is also

more dilated at its extremity, with but few non-incrassated costal venule, the margin

incrassated and more or less horny.

Panchlora, Burmeister et auctt. (ex parte).

Color pallide prasinus, elytris et alis hyalino-thalassinis ; vel brunnescens, rare fusco-irroratus. Oculi invicem

propinqui vel modice remoti. Pronotum corneum, levigatum, postice strigatum (disco rare punctato),

utrinque deflexum ; marginibus subreflexis, frequenter hyalinis, dense punctatis. Elytrorum vena discoi-

dalis tantum ultra medium a vena humerali sejuncta ; vena media indivisa, vena ulnaris in ramis paral-

lelis 4—6 divisa, venis spuriis inter illas nullis. Campi analis vene parum numerose. Lamina supra-

analis coriacea, incisa, frequentius prominula. Femora gracilia; anteriora apice mutica; 2°, 3* spina

geniculari minuta (frequenter deficiente) armata ; intermedia subtus margine postico, posteriora margine

antico, spinula apicali instructa.

Most of the species of this genus are of a milk-white colour, with a greenish tint,

like that of clear sea-water (¢thalassina). The lateral margins of the pronotum and the

basal costal area of the elytra are more or less transparent, margined at their inner

borders with a white opaque band. In dried specimens the greenish tint is often

lost and replaced by a pale fulvous colour; and the white bands of the sides of

the pronotum and elytra sometimes become rufous or reddish. Other species are not

greenish, and their white colour is shaded with a brown tint, sometimes very slight,

sometimes more pronounced on the elytra. In a few cases the pronotum is marbled

with brown.

The milky-greenish species are very difficult to separate, and some of them remain

uncertain, owing to the inconstancy and uncertainty of the details of most of their

characters.

To determine the species of this genus particular attention should be paid to the

following points :—

1. The distance between the eyes on the vertex in the 2 and in the ¢ (somewhat variable).

. The coloration of the antenne : with or without a black stump (subject to become pale or small).

8. The length of the supra-anal plate ?: produced beyond the last ventral segment, or not (this

may be a result of the mobility of the plate ?).

4, The form of the supra-anal plate ¢: (a) produced and bilobate; (4) short, transverse, broadly

subsinuated, and rounded on each side.

5. The form of the last ventral segment ¢: produced and arcuated; not produced ; truncate; or

emarginate. (Always somewhat, and perhaps occasionally very, variable.)

6. The number and position of the small black dots on the elytra in certain species: these are very

[\)

PANCHLORA. 91

fixed as regards their position, but one or the other may be accidentally wanting. The

dots are disposed as follows: (a) two typical dots beyond the middle—one on the furca-

tion of the discoidal vein, the other more distal on the median vein; (4) a dot on the

principal vein (vena humeralis) near the base of the elytra; (c) 1-4 small spots between

the branches of the ulnar veins at the base of the ulnar areas, at a short distance from

the anal vein. There is also often a black line on each side of the pronotum, and some-

times one on the anal vein.

These characters appear to be somewhat variable, but they are the only ones we have

been able to use to distinguish the lacteous species; it is therefore not improbable

that the number of species here catalogued may have to be reduced when more speci-

mens of some of them are available for examination.

The genus Panchlora seems to be exclusively American, but its species are very

cosmopolitan, being spread over the warm parts of the continent, and are likely to

become more widely distributed by being carried in merchandise from one country to

another. For this reason, and also on account of the great resemblance of some of the

species, we are obliged to enumerate them all.

In form this species resembles Z. maximiliani; it differs only in its large size, in

the lamina supra-analis (¢ ) being more rounded (in Z. maximiliant it is transverse,

having only the angles rounded), and in the reticulation of the elytra, the veins being

blackish. In Z. peruana, which it approaches in size, the margin of the pronotum is

not sensibly emarginate on either side of the cowl, the elytra are much wider and more

rounded at the apex, and the lamina supra-analis (?) is transversely quadrate; the

larvee of both species are of an ochraceous colour, marbled with brown.

Pronotum et elytra rugosa, piloso-velutina.

@. Caput minutum, reconditum, fronte inter oculos et antennas, excavata. Antenne medioccres, invicem

maxime distantes, 1° articulo cylindrico. Oculi in vertice invicem parum distantes. Pronotum transverse

fusiforme, latum, subplanum, asper, cucullatum, impressionibus 2 parum profundis. jus margines

anterior et posterior fere equaliter arcuati; anterior tamen in medio paulo minus arcuatus, caput valde

superans. Elytra amplissima, abdomen superantia, basi punctata, apice dense elevato-reticulosa ;

margine costali arcuato, apice late rotundato; sulco anali arcuato apice subtransverso. Al dense

reticulose, apice late rotundate, vena ulnari multiramosa. Pedes parum elongati, compressi; femora

inermia. Tibise antice supra spinis in margine interiore 2, in margine exteriore 1; posteriores supra

4:%, subtus 2:2. Arolia inter ungues brevissima, arcuata. Abdomen latum, deplanatum, lateribus

serratis; margine laterali segmentorum dorsalium dilatato, postice angulatim producto sed haud spinoso.

Lamina supra-analis 9 prominula, transverse subquadrata, margine posteriore subarcuato, in medio

This is a very remarkable genus. In its general shape Capucina agrees with the

“Tribe Panchlorine,” approaching Zetobora; but it differs from that genus in its

wide flat body, and in having the pronotum and elytra covered with a velvety pile.

The elytra are imbricate like those of Zetobora, but they are broader, with the marginal —

field very much dilated, as in the genus Schizopilia, Sauss.; but neither the elytra nor

the wings are so obtuse as in that genus. The lateral lobes of the abdomen are also

more obtuse than in Zetobora ; and the supra-anal plate is more deeply notched in the

middle and less transversely quadrate in shape, it being more like that of Schizopilia.

The middle and hind tibiz are less spinose than in the preceding genera of the Tribe

Panchlorine. Capucina is distinctly separated from Hom@ogamia by the posterior field

of the wings being much larger in proportion to the anterior field and folding in rest.

The supra-anal plate is not elongated as in Home@ogamia; the cerci are shorter ; the

legs are not long and slender, and not ciliated; the tibize are much less spinose; and

the claws have a distinct arolium, which is wanting in Homeogamia.

In this Tribe the hind wings are very peculiar in form. The posterior field is so

small that it can be drawn beneath the anterior field without folding; the anterior field

is very long in proportion, so that there is no apical margin to the wing, this being

transformed into the posterior margin of the anterior field and forming with the margin

of the posterior field the hind margin of the whole wing, without any interruption.

There is no anal notch, and in consequence of this the branches of the ulnar vein all

tend to the hind margin of the wing, none being true apical branches. These branches

are rather arcuated, with an anterior concavity, or are more or less transverse.

This small species approaches the type of L. mexicana, having very large membra-

naceous wings, and the elytra imbricate in their whole width, so that the interior

border of the left elytron covers the outer border of the right one. It differs, however,

from the type of LZ. mexicana in having the pronotum truncated and wrinkled ; the

elytra less membranaceous and more reticulated, the right one without a diagonal

nerve; the hind wings with furcated sectors; and the cerci with shorter joints. (Comp.

The specimen described has the abdomen broken. It is apparently a male, but it is

not impossible that it may prove to be the female of LZ. mexicana. If such is the

case, L. mexicana should form a separate group, both male and female having long

membranaceous elytra.

This genus is peculiar to Tropical America, extending also beyond the Tropics to the

south. Its species are rather numerous and extremely closely allied; they are very

difficult to distinguish, on account of the variability of their markings. We have

_ therefore considered it advisable to give a conspectus of all the known species, so that

those from Central America may be more readily identified.

The colour of the elytra is somewhat variable, the brown markings on the middle

being occasionally obsolete. The discoidal macula of the pronotum is also very

variable in form (comp. Tab. V. figg. 28-31), extending to, or distant from, the

anterior margin, and either adorned with ferruginous dots or not dotted at all. The

eyes in certain species are more approximated in some specimens than in others. The

femora bear typical spines, but they are obliterated in some individuals. These differ-

ences are not specific.

Tribus PANESTHIN &.

This Tribe is represented in North America by the genus Cryptocercus, Scudd., and

in South America by the genera Dasyposoma and Parahormetica. No species has yet

been detected in Central America.

Fam. MANTIDA*.

This family ¢ has been divided into “tribes” by H. de Saussure in his ‘ Mélanges

Orthoptérologiques. Stal has since proposed rather different divisions, introducing

useful modifications in the former system, but also some others which we cannot accept.

The classification of Brunner de Wattenwyl is a modified combination of these systems,

and as this seems to be the most correct we have adopted it here.

Nomenclature of the pronotum, head, and legs.

Pronotum: The pronotum of Mantide forms over the insertion of the anterior coxe a dilatation, some-

times altered in appearance when the margins of the pronotum are extended into lamellar wings (Charadodis,

Rhombodera, Deroplatys). The part of the pronotum extending behind the dilatation (pars postica) is the

shaft or stem (scapus); that extending before the dilatation (pars antica) and joining the head is the collar

(collum). This last part has at its base a transverse groove (sulcus swpra-coxalis), which breaks at a right angle

on each side, and frequently extends forwards in a direction parallel to the lateral margins of the collar, its

two lateral branches joining again anteriorly, separating the borders of the collar from its disc.

Heap: The parts of the head are:—Over the labrum the clypeus, in the form of a reversed trapezium,

divided by a transverse carinula. Over the clypeus the facial shield (scutellum faciale), very characteristic in

its various forms. Above this comes the forehead (frons), with the ocelli; over the forehead the vertex,

which is either at the top of the face or thrown back to the occipital part of the head, when the frons

becomes oblique. (HrzRopvtza.)

Lues: The anterior pair of legs and their armature present important characters for the distinction of the

genera. This is only to be expected, as these strongly raptorial limbs are the organs with which the Mantide

capture the living prey on which they feed. The femora are armed with two rows of spines, and bear besides

three typical spines at the base of their inferior face (spine basales, Sauss.; spine discoidales, Stél). When

the femora are short and the tibie about equal to them in length, three discoidal spines only are present ;

and when the tibia shuts upon the femur, its claw falls between the discoidal spines and the first spine of the

inner border. When the femora are longer and the tibie shorter, the claw of the tibia falls between the first

and second spines of the inner row, in consequence of which the first spine is separated and thrown more

against the disc. In this case the first inner spine has the appearance of a discoidal spine, and St&l

numbers it as such and says that there are four discoidal spines. It would be more correct to count only

three discoidal spines, and one separated spine of the inner row; but to facilitate diagnosis it is shorter and

more convenient to count, as Stal has done, three or four discoidal spines.

The Mantide are mimetic insects, green or grey in colour, and they are difficult to

detect amongst the leaves of bushes and trees. The males, which fly about in search

of the females, are more easily seen, having generally longer and membranaceous elytra,

and frequently less brightly coloured wings.

By means of their very strongly raptorial legs they are enabled to prey not only on

insects, but also on all kinds of small animals, especially on small birds, as noticed by

Robert Hudson *.

Several genera and species of the northern parts of South America which have

not yet been detected in Central America no doubt extend into this portion of the

American continent, as shown by the existence in the collections we have examined of

various small larvee which do not belong to the known Central-American genera, but

seem to agree with Brazilian types.

This species is very closely allied to C. rhombicollis, Latr. It has the pronotum ( )

similarly shaped; but the elytra are not quite so wide, with the costal field narrower and

the costal margin less arcuated beyond the middle. The black marking on the anterior

femora is placed beyond the unguicular sulcus and distant from the base; while in

C. rhombicollis this marking is placed before the sulcus and extends towards the base.

In the shape of the pronotum C. servillei agrees exactly with the figures of C. rhombi- —

collis given by Westwood and Wood-Mason. Wood-Mason’s figure of the pronotum

of C. servillei (¢ ) is too much rounded, not sufficiently pentagonal, and not narrowed

enough posteriorly, with the anterior margin rather too oblique.

Acontista is peculiar to the hot regions of America. It is a compact genus, composed

of small species, all of which have the same form and are very similarly coloured.

The males and females differ very much—the males having the elytra and wings

* The genus Astape, Stal, might be placed next to this, It possesses special characters in the proportions

of its legs. (Patria ignota.)

+ The name Acontistes being preoccupied in Aves (Sundevall, 1835), we adopt Acontista, Saussure.

ACONTISTA. 131

more or less hyaline, the females opaque elytra and coloured wings; consequently the

males cannot be attributed to their females with certainty unless caught in copula.

Moreover, great irregularities are apparent in the corresponding parts of the two

sexes, 7. €. in two species with very similar females, A. concinna and A. mexicana,

the male of the first resembles somewhat its female, having maculated elytra and

coloured wings, adorned with rufous as in the female, while the male of the second is

very different from the female, having hyaline or clouded elytra and hyaline wings ;

and, conversely, A. concinna, °, with broad elytra, has a male with very slender elytra,

while A. mexicana, 2, with narrower elytra, has a male with broad elytra.

All the females have much the same typical coloration, the wings being anteriorly

brick-red, posteriorly dark brown, and partly hyaline. The brown colour sometimes

extends over the whole wing (A. truncata), or it may be reduced to a mere arcuated

band, leaving a great part of the posterior field hyaline (A. amenula). It should be

mentioned that the brown parts of the wings are always of a very brilliant dark colour

(tortoise-shell-brown), with the transverse venule white or hyaline. The abdomen of

the females is generally wide and dilated, sometimes more fusiform; but in certain

cases it is very narrow, as in the males (A. amenula).

The males have membranaceous elytra, with the marginal field opaque-green (rarely

membranaceous), their costal margin becoming hyaline at its end. These organs seem

to be variable in each species, becoming more or less elongated and more or less slender

or broad.

In the females the facial shield is characteristic, being either transverse, narrow, and

flat, or more elevated, and divided into three parts, which are excavated. In the males

this structure is more obsolete and less characteristic.

In both sexes the supra-anal plate is rather prominent, but truncate and quite

transverse.

The armature of the anterior legs is the most striking character of this genus. The

tibize are furnished with numerous spines, which extend over their entire length; those

of the exterior margin, sometimes eighteen in number, are truncated, very short, and

contiguous to each other, forming together a crenulated border, as in the African

genus Harpax. Stal, on this account, has removed the genus Acontista into the tribe

Harpagine; but we, as also Herr Brunner de Wattenwyl, regard it as belonging to

the true Mantine. The anterior femora are stout, and the tibie sufficiently long to

reach, when drawn inwards, as far as their base; the claw, therefore, is not placed

between the first and second spines of the inner row of the femora, and, in consequence,

we find three discoidal spines only (comp. p. 124), and no sulcus on the inner face of

the femur. When the tibia is closed upon the femur, the claw is placed between the

discoidal spines and the first spine of the inner row.

The species of Acontista appear to be numerous, and numbers of them certainly remain

to be discovered. The females of the various species are so closely allied that they

can only be separated by small differences in size and in the coloration of the wings;

and they will certainly be confounded if these differences are not pointed out in a com-

parative synopsis, including all the known species. ‘The males are more variable and

still more difficult to determine than the females. |

The first two species have black wings in the females, and they form a special group,

having also the anterior femora and coxe maculated on the inner side. The other

species with tricoloured wings and immaculate anterior legs form a second group.

The distribution of the species seems to be very local, each being confined to a

limited region.

Stagmatoptera, Burmeister (ex parte), Handb. ii. p. 537.

This genus is essentially a Central-American type. It is very numerous in species

in the central parts of America and in the Antilles; and some of the Central-American

representatives extend into the southern parts of the United States, or into the

northern parts of South America.

Its species are somewhat heterogeneous, differing from each other in form and

coloration ; some are long and slender, others short and stout. The males, as usual,

differ very much from the females and present different types; but they are not

yet sufficiently well known to enable us to judge if they correspond to the differences

of their respective females, so that at present we cannot divide the genus into typical

sections.

The anterior legs are strong, not so long asin Phasmomantis. ‘The femora have their

exterior border occupied by spines for two-thirds of their length ; the apical spines are

small or wanting. ‘The anterior tibia have their outer border unarmed for a short

distance at the base ; but in the larger species the unarmed space is greater.

In the American Mantide two types of coloration in the hind wings of the females

are especially noticeable, particularly in the posterior field of these organs :—

1. Hyaline, tessellated with small opaque yellow bands placed on the transverse

venule.

2. Iridescent-brown, with the transverse venule generally hyaline.

These two types are sometimes characteristic of large groups, 7. e. in the tribe

““Vatine.” Inthe genus Stagmomantis both are to be found, most of the species belonging

to the first type (S. dimidiata, S. fraterna, S. domingensis), some others with fuscous

wings belonging to the second (S. tolteca, 8. cerulans); but it must be remarked that

the varieties of several of the species include the two forms. For example, S. tolteca,

with partly brown wings, has the transverse venule typically yellowish, but in certain

specimens they become widely yellow and nearly tesselated as in the first type; and

S. domingensis, the wings of which are usually clear and partly tesselated with yellow

bands, is subject to lose the opaque yellow bands and to become pale fuscous with paler

spots. In some specimens a part only of the wings is infuscated. It seems probable

that the coloration of the two types is sometimes reversed. Is not S. cerulans a mere

variety of S. carolina, in which, the fuscous colour has replaced the yellow bands

Saussure first united this insect with S. carolina, but we believe it must be regarded

as a distinct species, characterized by the broad cherry-red band which covers the

anterior half of the wings, becoming wider at the base, while the second half of these

organs is occupied by small opaque yellow fascize. The elytra are also differently

coloured, the part situated between the discoidal macula and the apical black band

being green or grey, somewhat marbled with black anteriorly. The males of the two

species cannot be distinguished from each other; but in the genus Stagmomantis the

males are very much alike in several species which are very distinct in the other sex.

This insect does not fit well into the genus Stagmomantis, on account of its robust

build—too short and thick for a male of this genus. The head, pronotum, and feet are

formed very much as in the females, and the abdomen also is distinctly more dilated

than in the males of Stagmomantis. The male described forms a passage to the corre-

sponding sex of Stagmatoptera, which it exactly resembles. It belongs, however, to the

genus Stagmomanizis, its facial shield being transverse, twice as broad as high (although

much higher than in the true Stagmomantis), the macula of the elytra unicolorous

(bicolorous in Stagmatoptera), and the anterior femora without marking. The elytra

are shorter and wider than in the true Stagmomantis.

S. androgyna may, perhaps, belong to the group of S. limbata. The black stigma

of its elytra resembles that of S. dimidiata, but it is larger than in that species, from

which it also differs in the elliptic form of the anterior part of the pronotum. This

last-mentioned character should approximate it to S. cwrulans, 2, but the size is too

large for that species. As regards size, S. androgyna would agree better with S. mon-

tana, 2; but it does not correspond with that species either, on account of the black

stigma of the elytra.

The true position of this genus is somewhat uncertain. It does not fit well into the

tribe Mantinz in consequence of its tuberculated pronotum and its very short legs, but

it can scarcely be placed in a different tribe.

It bears a false resemblance to Popa, Stal, on account of its short legs; but, except

for the two tubercles on the pronotum, it has no affinity with the Harpagine. On the

contrary, the form of the body and of the elytra, and the habitus of the female, are

quite those of Stagmomaniis.

Melliera bears some relationship to the Cuban genus Gonatista, Sauss., as it has the

collar of the pronotum not contracted and rounded anteriorly, and the intermediate

and hind femora incrassated at the base. In Gonatista the anterior part of the pro-

notum is slightly papillate (though not tuberculate), and the elytra, 9 and ¢, also

somewhat resemble those of Melliera ; but the legs are longer, and the armature of the

first pair is very different. Moreover, Gonatista belongs to the section of Mantinz with

elongate supra-anal plates.

We are of opinion, therefore, that Melliera should be placed next to the genus Stag-

momantis, although rather aberrant in this group of Mantine.

This genus comprises the largest representatives of the family Mantide. The males

and females are very different in the structure of their wings; but they are easy to

unite by the form of the pronotum and cerci. The species are very rare in collections ;

we know of only one.

The genera Macromantis, Metriomantis, and Hicetia form together a very natural

group, bearing much resemblance to Cardioptera; but that genus forms a parallel

group belonging to the tribe Vatine.

Only one (male) specimen existing in the collection, we are unable to state for certain

whether the Central-American insect really belongs to M. ovalifolia, Stoll. The

Nicaraguan male differs as follows from males of the typical species from Guiana :—

The marginal field of the elytra is green up to its base, with a small irregular hyaline

space along the principal vein at the base; the wings are somewhat more densely

reticulated, and their costal border is green only at its extremity. The cerci are

distinctly different, as described, but perhaps only on account of individual variation.

In the new classification the true Cardiopterw, having carinated tibie, are removed

to the tribe Vatine. The following species with uncarinated tibie therefore require

a new generic name, for which we propose Metriomantis. The limit of their distri-

bution in Tropical America is uncertain, and, like Macromantis and Stagmatoptera,

they are likely to extend into Central America.

Metriomantis should be placed immediately after Macromantis, and it is, so to speak,

a diminutive form of that genus. The form is similar; the head is also large and

triangular, flattened in front, with the eyes somewhat tumid laterally beneath. The

pronotum, however, is much shorter, and but very slightly widened anteriorly; the

wings have transverse yellow bands, very much as in Stagmomantis (but narrower) ;

and the anterior femora have at their outer border six or seven spines. The supra-

anal plate is not strongly produced, but wide and triangular.

The males are as yet unknown; but it may be assumed, from analogy, that they have

hyaline elytra.

It is possible that the males of some species at present referred to the genus Photina,

Burm., may prove to belong to Metriomantis.

Some small larve before us from Central America seem to belong to this genus,

perhaps to one of the species here enumerated. ent

This genus differs from Ameles in the position of the ocelli, and also in the long hind

other than they are from the inferior one, and the posterior metatarsus is scarcely

longer than the second joint of the tarsus.

This genus belongs to the group of Gonypeta, on account of its general form and its

very long hind metatarsus. Zitaneutria much resembles Ameles, but differs from it in its

long tarsi and coloured wings. The carinated pronotum seems to approximate it to

Tropidomantis, Stal; but in that genus the vertex is more elevated than the eyes, the

cerci are very long, the ulnar vein of the wings is biramose, &c.

Litaneutria appears to be the only American type known of the group of Gonypeta.

The females have probably abbreviated wings.

A genus containing extraordinary forms, resembling the slender Phasmide, with

beautifully coloured wings and short elytra. ‘The spines of the anterior femora are

rather long; on the inner edge the last spine is long, and it is separated from the

apical spine by an unarmed space. In the females the wings are semiorbicular; in

the males they are longer, but very obtuse, and widely rounded at tip.

The various species of 4ngela seem to be confined to the northern part of South

America and to the southern part of Central America.

Oés. Stal and Brunner de Wattenwyl have adopted the name Thespis, Serv., for this

genus; but the name Angela having been used by Serville for a subdivision of his

genus Thespis, it must be retained, and Thespis applied to the 7. sulcatifrons of

Serville (an African species). TT. livida and T. infuscata belong to the group

Miopteriges.

Group MIOPTERIGES*.

This group is composed of small species, all American, generally of a grey or fuscous

colour, of very slender form, with a stick-like abdomen in both sexes, the abdomen

with a triangular or lanceolated, carinated supra-anal plate.

In most of the genera the females are not winged, the wings being replaced by

striated lobes of the meso- and metathorax, as in the nymphs of Mantide in general,

but the lobes are neither articulated nor separated.

The antenne are somewhat moniliform and ciliated. The head is small, of elliptic

form, or much compressed, and the vertex has a tendency to form an elevated lobe

near each eye. The prothorax is carinated, short or long: when long, its extension -

over the coxe is very slight. The elytra and wings are very membranaceous and

finely ciliated, with a short pubescence on all their margins: this is one of the

principal characters of the group, and separates the Miopteriges from the similar

types of the Old World. In the hind wings the ulnar vein is either biramose or only

furcated ; its base is straight and continued in a straight line with the hinder branch,

while the vein itself, at its first bifurcation, is broken and directed more forwards and

arcuated. Frequently the elytra are somewhat shorter than.the hind wings. The

abdomen is always long and very slender, of stick-like form in both sexes, even in the

species with a short rhomboidal pronotum. |

The legs are slender, finely pubescent, with very long metatarsi, as long as or longer

than the other joints of the tarsi united; the intermediate and posterior pairs are elon-

gated, generally quite filiform; the anterior pair become more slender and elongated

as the prothorax becomes longer, according to the species, and in some types they are

- * =1,1. Stirps Mroprerrx, supra, p. 129,

MIOPTERIGES. 161

nearly filiform. In normal cases (Tab. X. fig. 9) the anterior legs bear on their outer

margin five, and on their inner margin a variable number of spines (the subapical spine

of each margin is generally distinct), and the discoidal spines are four in number ;

but the latter are sometimes difficult to distinguish from the other spines, when the

femora become much compressed. The femora, when short, are triangular, of normal

form and armature: when elongated, the spines are almost confined to the distal, or

even to the apical, part of these organs; in this case they lose some of their spines,

the space being inadequate for the development of the whole of these—that is, to

allow sufficient room between each for them to act as separate claspers. The proximal

part of the femora when without spines has its inner edge finely crenulated by a line

of small granules.

The length of the tibiee varies inversely as that of the femora, the long femora being

too weak to assist the clasping action of the long tibie at their extremity. In the

most slender forms the tibize are so shortened as to become almost rudimentary.

This modification is very striking in Oligonyx and Thesprotia. In these types the

shortness of the tibiee causes them to lose most of their spines, and those which remain

are partly transferred to the extremity of the organ; it thus happens that as there

is no room for one or two apical spines on the inner margin, they are forced

upwards and inserted over the last spine of the margin (Tab. IX. figg. 21, 28;

Tab. X. fig. 24), or even on the dorsal face of the tibie (Tab. X. figg. 7, 8). Do

these spines thus become useless ?

When the tibie are very short they cannot be opposed to the femora; they are, so to

speak, reduced to their claw, and it is the claw which alone presses the prey against

the spines of the femur. As the claw does not reach beyond the middle of the arma-

ture of the femur, the prey can only be caught between the claw and the smaller spines

which occupy the end of the femur, and seems to escape the long spines at the base

(Tab. X. fig. 9). But it may be presumed that, if caught, the struggling prey must

fatally impale itself on these spines by its own movements. It is therefore probable

that for this purpose the species with short tibiz have some of the discoidal and basal

spines very long and perpendicular. |

The conclusion to be drawn from this organization is that the elongate Miopteriges,

and perhaps also the other allied species, hunt very small prey only, probably soft

insects. |

The species of the Old World which have been referred to Miopteryx, and also those

of allied genera (as Parathespis, Sss., and Hoplocorypha, St.), do not belong to the

group Miopteriges. They constitute a parallel series similar in form, but with

glabrous wings and feet.

This genus includes the larger species of the group Miopteriges. Although occa-

sionally very elongate and slender, the body is somewhat more robust than in the other

genera. The spines of the anterior tibie are generally very regular, but they are

sometimes unequal in length; the innermost spine is placed in its usual position, and

is not transferred upwards to near the insertion of the claw as in Mionyz.

To this genus belong the following species :—Thespis conspersa, Sss. (South

America); vicina, Sss. (Colombia); and Yinfumata, Serv. (Brazil).

This genus is closely allied to Musonia. ‘The forehead is not flattened, and the

anterior tibiz are not so closely spinose; the spines are short, unequal on the inner

side. The principal difference is in the position of the last spine on the inner margin

of the anterior tibiz, this being transferred upwards to near the claw.

triangular, and the pronotum short and more broadly dilated. The wings are also

differently coloured ; they are broader than in W/. sevus, and narrower than in WW. ferus,

but as the apex is shaped nearly as in the latter, the anterior field is not so much

projected beyond the posterior.

In this very singular genus the anterior legs are more aberrant in form than in any

other type of the Family Mantidz. The femora are strongly compressed, and have a

single spine only on the outer margin (difficult to distinguish), this being placed close

to the long spine of the inner margin. The tibis are so rudimentary that they cannot

be opposed to the spines of the femora for grasping purposes, except with their long

claw; they are truncated, and terminate, so to speak, in four spines, of which one,

placed on the superior face, large and arcuate, appears to be a very powerful weapon.

For what purpose the tibiz are thus formed, or how these insects are able to capture

their prey with such a weapon, it is impossible to understand. They probably live on

very small insects.

Stal has separated these Mantids from the genus Oligonyz, Sauss., on account of the

rudimentary anterior tibiz, the very long filiform body, and the more compressed elevated

vertex. ‘They agree very nearly with that genus, but the armature of the anterior

tibie, although belonging to the same type, is rather different, the last two spines of

the inner side being equally apical; the penultimate spine, however, instead of the

apical (which is smaller and contiguous to the claw), is transferred upwards.

Thesprotia seems to be a South-American type, but it probably extends to Central

America.

Mantis filum, Licht., from Surinam, probably belongs to this genus.

In this genus the body is neither so elongated nor so slender as in 7hesprotia; some-

times the pronotum is short, as in Miopteryx. The head is more transverse, with

swollen eyes; and the vertex, although compressed, and with two juxta-ocular rounded

lobes, is not, or but little, elevated. ‘The form of the anterior tibie is the most evident

character of the genus, not bemg truncate as in Thesprotia (although still short), but

slender and armed with more numerous spines.

The genus is peculiar to Central and North America. ‘The following known species

belong to it:—0O. brunneri, Sss. (Colombia) ; 0. scudderi, Sss. (North America, Georgia) ;

Q. whleri, St. (Louisiana); Mantis parva, Drury (Miopteryx parva, Sss.) (America) ;

In this species the prothorax is relatively much longer than in O. bollianus ¢ , and

only half as broad; the elytra are also proportionately shorter. The wings are not

quite so narrow as in O. striolatus, and the longitudinal veins of the elytra are not so

straight. ‘The middle vein and the first ulnar vein are slightly bent at about three-

fourths of their length. The anal (subapical) emargination of the wing is more obtuse

than in the other species of the genus, somewhat as in Harpagonyx gryps.

In this species the wings are narrow, and the costa of the fore pair is but very little

bent at the tip, and, consequently, the longitudinal veins are nearly straight, sub-

parallel, and not so distant from each other as in O. tessellatus and O. punctulatus.

Hab. Mexico, Dos Arroyos in Guerrero 1000 feet (A. H. Smith).

The veins of the elytra and of the apex of the hind wings are alternately brown and

hyaline, that is to say, with short, brown spaces interrupted by hyaline segments ;

towards the tip the veins are dotted with brown. The wings of this species are shorter

than in O. striolatus and O. tessellatus; the nervures are less arcuated than in O. tessel-

latus, but more than in O. striolatus.

5. Oligonyx tessellatus, sp.n. (Tab. IX. figg. 26-31.)

3. Fulvescens, 0. striolato simillimus ; pronoto tamen breviore. Caput minus latum. Prothorax brevis, fere

subgranulata, trigonalis, scilicet marginibus totis convergentibus, collo breviusculo, haud parallelo;

marginibus vix denticulatis. Elytra et ale grandia, abdomen superantia, nebulosa, fusco-punctulata,

margine anteriore apice valde arcuato, venis discoidalibus itaque apice curvatis (plus quam in O. punc-

tulato). Elytrorum vene campi discoidalis elongato-fusco-tessellate, ut in specie laudata, et ad venas

griseo-maculose ; inter illas, saltem in dimidia parte apicali, griseo-punctulata; venulis transversis insuper

ad exsertiones fuscis; venis media et ulnari magis obliquis; areis longitudinalibus disci propter hoc

latioribus. Alarum pars apicalis fere eodem modo quam elytra tessellata. Pedes antici fusco-fasciati,

paulo minus graciles ac breviores. Coxe retro prothoracem superantes, margine antico remote denticulato,

superiore subtilissime serrulato. Femora margine infero-interno basi tantum in tertia parte inermi, vix

crenulato. Tibia spina exteriore subrecta, margine interno prope basin denticulis 2, Lamina supra-

analis trigonalis, apice hebetata, a stylis superata.

Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith).

A remarkable species on account of the short prothorax and the large elytra and

wings, the latter with more arcuated nervures than in the other representatives of the

genus. The ulnar veins of the anterior wings are also more oblique, not reaching so

far as in the allied species, and more distant from one another.

3 do. Elytra et ale illis generis Olygonichis conformia.

In this genus, as in Thesprotia, the armature of the anterior tibiz is nearly reduced

to the claw. The outer spines are rendered useless in a most extraordinary way by

their curving back against the tibia. (Tab. VIII. fig. 4 6.)

In this very curious type the anterior tibie are armed, as in Oligonyx, with only four

spines ; but the two spines of the inner margin are curved against the tibia, with their

points applied against its inferior face (comp. Tab. IX. fig. 21), so that they seem to be

of no use for capturing prey. The single spine of the exterior margin is quite apical,

it being placed under the point of insertion of the tarsus f; it is, however, sometimes

obtuse or atrophied. The claw and upper spine appear to be the only weapons that can

be used for grasping purposes.

It would be interesting to know how these insects capture their prey, and for what

purpose the inner spines have their points recurved against the tibia, so as apparently

to render them useless.

* dpraé, ferocious; dvvé, claw.

+ This spine is often difficult to detect: it is best seen by examining the tibia from its inner face and

somewhat from below.

This is a well-marked genus, characterized by its short form, large wings, and very

slender legs; and, principally, by the anterior tibize being curved upwards, their

armature resembling that of Thesprotia and Spanionyx (comp. Tab. X. fig. 2). The

terminal claw of the anterior tibie is small, straight, and spine-like. Theinner margin

(Tab. X. fig. 8) bears two spines beyond the middle, as long as the claw, and two

of the other spines are transferred from the margin on to the dorsal face of the

tibia and are scarcely less apical than the claw (the inner one shorter than the outer,

this last corresponding to the dorsal spine of Thesprotiat). Altogether, there are

five if there is only one, six if there are two, on the outer margin.

In addition, the inner margin before the spines is finely crenulated and bears two or

five or six spines

three small obsolete denticulations.

* Apivaé, fork ; ovvé, claw. (The anterior tibie with two spines or claws at the apex above.)

t+ The two dorsal spines are difficult to distinguish. They are best seen when the tibia is examined from

above ; in profile, only one is visible (the inner)—it looks like the claw, being as large and slightly more

apical than the claw itself. The true claw, placed under the two dorsal spines, appears as a third spine

of the inner margin.

This is the only known species having the prothorax twice as long as the anterior

cox, S. predicatoria, Sauss., excepted. It differs from the latter in having the

pronotum finely denticulated, quite finely at its base; the macula of the elytra

somewhat different, having a thick triangular white stigma without the white arch ;

and the macula of the femora almost obsolete. SS. septentrionalis may be easily

distinguished from S. annulata, Stoll, by its: longer prothorax, its very much larger

elytral macula, and its anterior femora without distinct marking. The head is some-

what narrower than in the other species of the genus, forming in the 2 a regular

triangle, its three sides being of equal length, as in S. preedicatoria, while in most of

the other species the head is distinctly wider than high.

A genus composed of smaller species than Stagmatoptera; with the head not so

regularly triangular, somewhat less high, the prothorax shorter, and the elytra without

a coloured ocellus. In the males the elytra are hyaline, with the costal field more or

less green, and the antenne are distinctly serrulated.

A small larva from Costa Rica perhaps belongs to this genus, the known species of

which are all South-American.

Stal described three other species allied to O. rubicunda: O. acutipennis, O. media,

and O. obtusa, all from South America. A small larva from Costa Rica perhaps belongs

to one of these species; in any case it shows that either this genus or Parastag-

matoptera extends into Central America. This larva has the eyes less acute than

in O. rubicunda, but less rounded than in O. icterica. The anterior part of the

pronotum is elongate-ovoid, as in O. rubicunda; but the pronotum itself is much

shorter. The anterior tibia are unarmed at the base of their exterior margin, as in

We only know this species by Drury’s figure. All the authors, except de Haan, have

confounded it with the insect figured by Stoll, Spectr. et Mantes, t. 9. fig. 32 (7. stollt).

It forms a transition from the type of 7. chlorophea to that of T. paralleia, the elytra

being strongly sinuated at the end and the wings not pointed (as in 7. chlorophea),

while the head is only bituberculated (as in 7. parallela *).

Obs.—T. cingulata, Stoll, belongs to a different species (comp. 7. stolli). Lichtenstein,

Serville, Burmeister, Guérin-Méneville, Saussure, and Westwood have confounded the

species of Drury and Stoll; the synonymy of these authors must therefore be completely

excluded. |

We regret that Stal has applied the name Vates to the genus Zoolea, Serv.; this

interpretation causes great confusion in the synonymy of the species. The first

Vates described by Burmeister is V. cnemidotus (= subfoliata, Stoll), so that the name

_Vates of Burmeister must be reserved for this type; while Zoolea must certainly be

retained for the genus of Serville. In this way all confusion is avoided.

This species is the only one as yet known in Vates and the allied genera in which

the male has the elytra rather opaque and coloured as in the females.

We are unable to find any difference between the Mexican specimens and the typical

V. paraensis, except that they are larger and have the legs more strongly lobed.

Saussure only knew V. paraensis from a rather bad specimen, with the frontal horns

broken.

This species is allied to V. longicollis, Stél (Syst. Mant. p. 74. 1; incompletely

described), which, however, has a lobed abdomen, and, apparently, a longer prothorax.

The anterior part of the prothorax is much like that of V. folteca, Sauss., the collar

being short, and the coxal lobes rounded and prominent, but still more so than in

V. tolteca.

This species is very closely allied to V. subfoliata, Stoll, which has similarly shaped

wings. But in V. subfoliata the anterior part of the pronotum is less dilated, the

femora have no lobe on the superior margin, and the lobes of the tibie are elongated

and rounded (in V. pectinata the lobes are all truncate or emarginate on their apical

margin, and, therefore, angular or acute). In JV. subfoliata (3 ) the frontal process is

acute, while in V. pectinata it is divided into two horns which have separate points.

198 ORTHOPTERA.

Fam. GRYLLIDE*.

The members of this family resemble the Locustide in their saltatorial habits, and

also in being furnished with an ovipositor f; they have long setaceous antenne, and a

musical apparatus on the elytra. The Gryllide form, however, a very distinct family,

differentiated from the Locustide by the following characters :—

1. The tarsi are only 3-jointed.

2. The elytra in. repose lay flat on the body ; their discoidal field is united to

the anal field, so as to form a single dorsal plane, and not well separated from each

other; their marginal field alone being deflexed perpendicularly downwards, covering

the sides of the body.

3. The tympanum or musical organ of the elytra extends on to the discoidal as well

as the anal field, and often covers it almost entirely.

In the Locustide the tarsi are 4-jointed ; the discoidal field of the elytra is joined on

a single plane with the marginal field, and occupies a lateral, somewhat perpendicular,

position, the anal field alone remaining in the dorsal plane: the musical organ of the

males is thus confined to the anal field.

The family Gryllide having already been monographed ff, it is unnecessary to repeat

here the synopses of genera, or to give detailed descriptions of them.

The Gryllide may be divided into six tribes as follows :—

Gryllotalpiens, Saussure, Miss. Scient. Mex., Orthopt. p. 333 ; Mélang. Orthopt. ii. fase. 5, p. 186.

The Gryllotalpine are of subterranean habits and are partial to water *. The species

of the first group (Gryllotalpites, Sss.) are furnished with a clothing of velvety hairs,

which protects them while burrowing. They swim admirably well, their anterior feet

being as well adapted for swimming as for digging. The species of the group Tridac-

tilites are entirely aquatic. They live on the sandy shores of rivers, digging galleries

in the sand and running, or rather skating, on the surface of the liquid element.

When submerged by waves or the whirl of the current, they swim admirably with

their hind tibie, which are sometimes furnished with articulated paddles, acting like

oars; or they dart through the water—their very strong hind legs enabling them to

take enormous leaps—till they reach the surface again.

the flower-beds of gardens and to cover the wetted places with pieces of board; in the morning some of these

insects are almost sure to be found under the boards disporting themselves in the mud.

+ This name is older than Gryllotalpa, having been employed by authors anterior to Linneus. It is

derived from curtis, garden, curtilla, gardener. The French word courtilére is derived from this.

Tridactyide, Brunner von Wattenwyl, Prodromus d. Europ. Orthopt. p. 453.

The two genera forming this group are nearly allied to the true Gryllotalpine, but

differ from them by well-marked characters ; I therefore follow Brunner de Wattenwyl

in separating them from the Gryllotalpine {. The group Tridactyline has an evident

affinity with the Acridiide. |

Its principal characters are as follows :—

Short, filiform antenne ; coriaceous elytra, in repose sometimes united and forming

a roof, as in the Acridiide; flabelliform wings, divided by a transverse nervure, and

when at rest forming at the tip a compressed lamella, as in the Acridiide ; exceedingly

wide hind femora and a very curious elongate armature of the hind tibie, giving to

these insects an enormous saltatorial power 4; two-jointed anterior and intermediate

tarsi; and the hind tarsi with one joint only.

But the most striking character of this group lies in the fact that the end of the

abdomen bears four appendages, which is a unique exception in the Orthoptera.—

The homology of these appendages has not hitherto been established with certainty.

Dissection shows that the two superior ones (Tab. XI. figg. 3, ¢.—8, ce.—9, ¢.—10, c)

are the homologues of the cerci of the Orthoptera, and that the inferior ones (Tab. XI.

figg. 3, a.—8, a,—9, a) are formed by very curious processes of the inferior valvule of

the anus (Tab. XI. fig. 10, a)*. The four appendages, notwithstanding their resem-

blance, are thus proved to be of quite a different nature. -

All the Tridactylinze seem to have fossorial habits. They live in the sandy beds of

rivers, and run and jump with great agility on the surface of the water. When

submerged by the whirling of the current, they hop with the utmost vigour in their

endeavours to reach the surface, and when that is gained they make tremendous leaps

to reach the shore f. '

The aquatic habits of these interesting little insects explain, perhaps, the use of their

four anal appendages. When submerged, they carry with them little bubbles of air,

between the hind femora and the abdomen, which perhaps enable them to breathe

under the water, and, acting like bladders, bring them again to the surface. It is

probable, too, that bubbles of air are also retained between the four pubescent anal

appendages; but I have not succeeded in verifying this with sufficient certainty, on

account of the rapid movements of the insects.

The affinities of the two genera composing the group Tridactyline are not the same,

and it is surprising that two types so similar to each other incline towards two different

families: Tridactylus being more allied to the Gryllotalpine, having no ovipositor

whatever ; while Rhzpipteryx inclines towards the Acridiide, as will be seen below.

These small insects are closely allied to Gryllotalpa. The body is similarly formed ;

the head is conical, directed forwards, well suited for progression underground ; the

anterior tibie are strongly fossorial, and are used for digging galleries in the sandy

shores of rivers, instead of in the fields, as in Gryllotalpat. The females have

no ovipositor whatever, and the abdomen has consequently the same number of

segments in both sexes. This is the reason why the males had never been properly

distinguished from the females.

There is, however, a difference to be noticed between the sexes: in the females of

T. variegatus the penultimate ventral segment has generally a slight notch in the

middle of the hind margin (Tab. XI. fig. 6), and it is followed by a sort of appendage

Serville, Orthoptéres, p. 313.)

in the form of a small segment, which is parted in the middle * (though not always

projecting beyond the true segment). This appendage is certainly homologous with

the inferior valve of the ovipositor, which are formed by the connecting membrane of

the eighth segment. The last ventral segment is parted by a ridge, a character

indicating a tendency of this segment to divide into two parts, so as to form the

superior valve of the ovipositor. The structure of the eighth and ninth (seventh

and eighth as seen without dissection) segments shows a rudimentary, but evident,

tendency to the formation of an ovipositort. In the males (Tab. XI. fig. 2) the

last two ventral segments are simple, without any such modification, and the terminal

one is almost square.

Nevertheless, the two sexes are not always easy to distinguish on account of the

characters of the females being rather variable. Generally, the appendix of the eighth

segment is not produced and apparent, and in some species the notch of this segment

is obsolete—e. g. in T. histrionicus, the eighth segment in this insect being, on the

contrary, produced in the middle, instead of notched (Tab. XI. fig. 1).

The differences between the sexes are best summarized as follows: 92, last: ventral

segment usually parted by a ridge, the hind margin of the preceding segment notched

or produced in the middle; ¢, the last ventral segment entire, the penultimate

segment transverse, entire.—In both sexes the cerci (Tab. XI. figg. 1, 2, 3, c) are two-

jointed, and the anal appendages (Tab. XI. figg. 1, 2, 38, a) are entire and cylindrical.

- Several species of Zridactylus have been characterized only by their markings and

by the length of the wings; but the colour is of slight importance in this genus, the

yellow markings being subject to disappear altogether, and the wings are very variable

in their length, tending to atrophy in specimens of the same species. The real

distinctive characters are to be found in the size, in the armature of the hind tibie,

and in the length of the posterior metatarsus ; also, in some species, in the form of the

anterior tibie (¢ ), or in the structure of the last ventral segments ( ? ) {.

The Tridactyli are found abundantly, and with similar forms, in all parts of the

world, except apparently Australia.

t It has been admitted that in some Tridactyli the anterior and intermediate tarsi are composed of three,

and in others of two joints only. A careful examination of all the species in my possession has proved that

the tarsi do not in any case possess more than two joints. The illusion of their possessing three joints is easy

to explain by the fact that the first joint of the intermediate tarsi is lobed (Tab. XI. fig. 5), and appears under

the magnifying-glass as if divided into two parts, and also by the fact that the lobulum in which it terminates

is often accidentally curved downwards and takes the appearance of an additional joint. Examination

under the microscope explains these appearances. In consequence of this, the classification of the genus,

as established formerly by Burmeister and by myself, should be modified: the divisions Xya and Tridactylus,

Sauss., will form a single division only, and the name Xya, as the more recent, must be excluded. The

Central-American species must thus be co-ordinated with the synopsis here given.

Hab. Nortn America, Southern and Western States, Texas (Bol/).—-GuaTEMALA, San

Gerdnimo (Champion).

The very extraordinary form of the anterior tibie of this species should be well

understood. The tibia is very broadly and deeply emarginate at its superior edge, and

thus divided into two divergent branches. ‘The upper branch terminates in two spurs.

The inferior branch (¢) is very elongate and attenuated at the tip: thus it has lost one

of its spurs, and the other spur has grown to an enormous size, forming a regular claw.

This branch bears the tarsus (s).

Obs. 1.—Burmeister, in his diagnosis of this species, describes the anterior tibie in

an unintelligible manner. It would appear that in his insect a tibia had been broken

off and repaired by gluing the end of the inferior branch (¢) to the femur; thus he

could regard the tibia as being very thin at the base and dilated at the end... ?

Obs. 2.—It has been stated that 7. apicalis is found also in the East-Indian region.

This is a mistake; it is a purely American species. The Indian insect referred to

T. apicalis belongs to a different species, well characterized by the form of the anal

pieces of the abdomen, which greatly resemble those of 7. miatus.

Obs. 3.—It is a question whether the extraordinary form of the anterior tibia is

characteristic of the males only, or common to the two sexes. If it is peculiar to the

males, 7’. incertus (no. 3) might prove to be the female of 7. apicalis.

Of the size of 7. apicalis. In the males the anterior tibiz are parted at their apical

margin by.a cuneiform notch, and each portion of the margin forms two triangular

teeth, each bearing one of the four spurs. In some specimens the notch is less distinct,

and the tibie thus resemble those of the females in general. |

In the males the last two ventral segments of the abdomen are lamellate, the penul-

timate segment transverse, the terminal plate nearly square when it is unfolded, as in

7. mixtus—more or less elongate, according to whether the segment is extended or

contracted.

Rhipipteryx seems to be almost as nearly allied to the Acridiide, especially to the

genus Tettir, as to the Gryllotalpine. Indeed, all their general characters are more

those of Acridiidee: head perpendicular ; the pronotum in the shape of a saddle; the

anterior legs longer, more slender, and less fossorial than in the T'ridactyli; the elytra

placed on the back in the form of a roof; and the females with a short ovipositor,

much resembling that of the same sex of the Acridiide. Nevertheless, Rhipipteryxr

has an intimate relationship with the Zridactyli.

Their habits are not known, but it is probable that they are very similar to those of

Tridactylus. ‘The species of Rhipipteryx are presumed to burrow in the sand, for their

anterior tarsi can be doubled up in the ridge of the tibize, so as to leave the apical spurs

of the latter free, as in Tridactylus; but, having longer and thinner legs, their digging

power must be weaker, and, their posterior tibiz being destitute of pallets, they are very

likely not so much aquatic, 7. e. not such good swimmers as some of the Tridactyli.

Their lighter colour suggests, however, that they move about still more easily than

the latter on the surface of the calm water, helping themselves with their extended

wings *,

In Rhipipteryx the cerci are obsoletely multi-articulate. The anal appendages of

the females are obsoletely parted in the middle; the apical half being compressed,

dilated, and of ovoid form (Tab. XI. fig. 10). The last dorsal segment of the abdomen

of the males is frequently very abnormal in form, it being in some species much

widened and reflexed, 7. e. strongly modified as in various Acridiide. When this is the

case the cerci and the anal appendages remain small and slender (Tab. XI. fig. 22).

The genus Rhipipteryx is peculiar to America; it does not extend so far into the

temperate regions as Tridactylus.

The parts of the mouth of Rhipipteryx having never been described, I give figures

of them :—Tab. XI.: figg. 17, labium ; 18, maxilla; 19, mandible. The labium much

resembles that of Tridactylus; the third joint bears paraglosse, with membranous

apex (in Zridactylus these appendages are two-jointed).

Explanation of fig. 20.—The 8th and 9th dorsal segments of the abdomen are reflexed upwards, as in the 9th

segment of R. cyanipennis (Tab. XI. fig. 22). The 8th segment is broadly trapezoidal, with a wide notch

placed between two acute little lobes. The 9th segment (9) is corneous, opened, and raised, shell-like.

In the middle under its margin appears the small supra-anal plate, which projects beneath two long

processes (u), both being flattened and sulcate, curved downwards at the tip. The cerci(c) and anal

appendages (a) are short, and when seen from above appear to be conic; the anal appendages when seen

from the side are more rounded; the infra-genital plate (i) is parabolic and somewhat trilobed at

the tip.

organs are visible the four corneous valve of the short ovipositor, which have been separated from each

other: the two inferior valve (8 u) formed by the membranous appendix of the 9th ventral segment; and

the two superior valve (9b, 90) formed by the appendix of the 8th ventral segment.—Fig. 9. Shows the

its real ovoid shape. The anal appendages (a), removed outwards, show at the base the inferior valvule

of the anus; they appear as if biarticulated, but they are only incompletely so; 7, the intestinal tube.—

In this and the following tribes the neuration of the elytra of the males affords

important characters for the separation of the genera and species, in most of which

nearly the whole organ is modified in a very extraordinary way, to form a musical

instrument. It is thus necessary to make perfectly clear the nomenclature of the

nervures of the elytra (vide Tab. XIII.*).

In all the Gryllide, except the Tridactyline, the elytra are divided into two fields:

the lateral and the dorsal. The latter is formed by the discoidal and the anal fields

being united into one, and lying flat on the back of the insect. ‘The two parts of the

elytra are separated by a more or less sharp ridge formed by the two principal veins.

The first part is formed by the humeral vein (vena humeraiis) ; but this deflexes laterally

at its middle, and it is the discotdal vein (v. discoidalis) which continues the ridge in

its second part. The medial vein (v. media), nearly contiguous to the discoidal vein,

rests on the back and belongs only to the dorsal field.

The lateral field contains:—a, the mediastinal vein, parallel to the ridge of the

elytron; it is simple or (more generally) ramose ;—0, 3-4 free veins, quite at its base,

generally short (except in the Trigonidine).

GRYLLINA. 217

Females (Tab. XIII. fig. 18).—On the dorsal field are:—a, the medial vein (m),

next to the ridge, generally rather slender and furnishing at its extremity a few short

apical branches ;—d, the wlnar vein (uw), furnishing often three obliquely pectinated

branches ;—c, the anal vein, oblique ;—d, 2-3 axillary veins, terminating, like the

anal vein, on the inner margin (margo suturalis) of the elytron.

Males.—In some genera there does not exist a musical organ, and in this case the

male elytra do not differ from those of the females.

But in most of the Gryllide the musical organ is extremely well developed in the

males, and the elytra, except their apex and base, are converted into a tambourine.

The membrane is no longer rough, but transparent and parchment-like, not only on

the dorsal, but also on the lateral field. In the lateral field the nervures are the same

as in the females, but the vena mediastina bears a greater number of branches, and

these often take a sigmoidal curve. When the females possess a simple mediastinal

vein, the males of the same species have at least one (apical) branch. In the dorsal

field the nervures are so much deflexed that it is not possible to recognize them

except by a special study. I have given their nomenclature in a footnote on p. 216,

and will now endeavour to explain their homology.

Homology.—All the longitudinal veins of the discoidal field, except the vena media,

instead of being straight, are angularly broken before the middle and deflexed

inwards nearly up to the sutural margin of the elytron.

The vena analis (a, a') forms thus a right or obtuse angle, and becomes more or less

transverse, to form the stridulating part (A), and then becomes longitudinal again (a’).

The other nervures follow the same direction. The transverse part of the v. analis (A)

is much thickened, prominent on the inferior side of the elytron, and is furnished with

rugosities like a file. It is by rubbing these rugosities against the inner edge of

the other elytron that the insect produces its musical sounds. ‘This part of the anal

vein has been named by Goureau archet (bow) (plectrum, Sss.)f. It is, indeed,

exactly like a fiddle-bow in its constitution and mode of action. As the right

elytron in the ordinary position covers the left elytron, it is generally the right which

produces the sounds by rubbing on the left one; but the elytra can be indifferently

superposed at the will of the insect, and the left elytron sometimes rubs against

the right f. |

The three avillar veins (a, x', x") run obliquely to the sutural margin. The first

two (xz, v’) converge generally into a single short nerve, which is anastomosed with the

inner end of the vena stridulans (A); the fusion of these veins forms a corneous knot

(nodus analis) (n), which furnishes a solid support for the end of the vena stridulans

* On fig. 9 the dotted line of the inferior z has been made too long, going through to the speculum.

and for all the nervures of the tympanum. After having thus been fused together,

the three nerves separate again and become longitudinal. The v. post-analis (a’) is

the continuation of the v. analis (stridulans); it is often united to the v. diagonalis

or to the speculum by from 1-8 venule. ‘The first and second v. post-axillares (2, 2’,

fig. 9) are the continuation of the first two vene axillares («, 2’, fig. 22). The third

v. axillaris (x) is not deflexed like the preceding veins, but becomes quite marginal (2"),

and extends along the sutural margin of the elytron; before it reaches the anal knot

it is somewhat thickened and forms the inner margin of a sort of conchoid excavation,

the latter being more or less corneous, but with a small membranous area. This

peculiar organ, called by Goureau chanterelle (illex), is the generator of the sounds,

as proved by the fact that it is on its margin that the archet rubs and produces the

vibrations, which, through the anal knot, are carried to the nerves of the whole

tambourine. ‘The little musical field is of a different form: it is much developed and

conchoid in the Grylline, but becomes very narrow and but slightly apparent in the

Eneopterine *,

The vena diagonalis (6) has a less evident homology. It must be identified

with the v. ulnaris, by supposing that it has been deflexed and broken angularly

together with the v. analis. Indeed, the proximal part of this vein, pressed against

the v. analis, has disappeared, and seems to have fused with the vena stridulansf,

so as to make this thicker and more robust ; and it only emerges again before the knot.

The v. diagonalis is a strong vein, supporting the speculum (s), which is an important

drum.

The speculum (figg. 9, 21, s) results from the bifurcation of the diagonal vein. Its

outer margin (d') is formed by the apical part of this vein, which posteriorly curves

into an elliptic form. Its inner margin is formed by the first branch of the diagonal

vein, which joins the end of the nerve of the outer margin (d), so as to close the field.

The speculum is parted transversely by a second branch of the v. diagonalis, sometimes

by two branches; in rare cases by numerous branches of arched form (Tab. XII.

fig. 4). The speculum as described is anteriorly angulate (fig. 21), but often takes

an ovate form (fig. 9); its outer angle is anastomosed with the v. media (m) to form

the stigma (1). The vene post-analis (a') and post-axillares (z, z') anastomose together

at their extremities (fig. 9), forming closed elongate cells.. The vena invo/vens (fig. 9,7)

is very irregular. It may be formed by the prolongation of the v. media (m) through

* If the v. stridulans is to be compared to a fiddle-bow, the 3rd v. axillaris (a#'') on which the bow rubs,

and also the vene post-analis and post-awillares emerging from the anal knot, should be compared to the

chords or strings of the instrument. Nevertheless, I must abandon the term chords or strings in order to

avoid confusion.

+ This appears to me to be the more certain, as in the females the ulnar vein has often a common origin

with the anal vein (figg. 6, 18).

GRYLLINZ, 219

the stigma, by the prolongation of the third v. post-azillaris (fig. 9), or even by the

crossing of the two branches of the v. diagonalis (6) which form the speculum (fig. 21).

It is very variable, forming often one, two, or three cells, through its occasional

anastomosis with the margin of the speculum.

The area apicalis (r) is unmodified, and does not belong to the tambourine. It is

formed by the apical branches of the v. media (m), the last three or four of which are

strongly curved inwards, the base of these branches being turned back by the speculum,

and the preceding two or three branches emerging from the v. involvens (7), the bases

themselves being confused with this vein. But in consequence of the variability of

the anastomoses and of the cells, the apical branches of the v. media seem sometimes

to belong to the extremity of the post-anal veins.

Adventitious musical veins (vene oblique and vene transverse). —The homologies

of all the normal veins as modified in the male elytra are thus explained, but there

are still in the tambourine of the males other musical veins (v), occupying the large

discoidal cell, between the v. diagonalis and the v. media. These nervures are to solidify

this cell, and, besides emerging directly from the v. stridulans, they receive probably

special vibrations. They afford useful characters to the systematist by their number,

direction, and form, and are characteristic of the tribes and through the tribes of the

genera, as will be shown below. They are of two different types :—

(a) Vene oblique, sensu stricto.—These nervures exist in variable number, extending

more or less obliquely from the vena stridulans to the v. media; the posterior (inner)

one anastomoses sometimes at its base by an arch with the v. diagonalis (fig. 9, v);

often they anastomose all together at their base by such arches, and are united to the

v. stridulans by adventitious reticulation. In addition, there are often at the outer

angle of the v. stridulans or v. analis (a) a few very short, rudimentary, false oblique

veins (Tab. XII. fig. 14), which may be taken as the homologues of the transverse

venule of the normal reticulation, and which do not belong to the drum. But the

limit between them and the real oblique veins cannot well be defined.

(b) Vene transverse.—These are never more than two in number, and they are found

only in a few genera of the group Eneopterine, and give to the tambourine a very

typical character. In this type the vene oblique, as described, do not really exist,

except a rudiment of the last one forming the arch which unites it to the base of the

diagonal vein (figg. 22, 23). They are replaced by two transverse veins (v), which are

anastomosed with the base of the single rudimentary oblique vein.

The true oblique veins I consider to be purely adventitious. ‘There is nothing

homologous to them in the elytra of the females. They (fig. 9, v.) appear to be

formed by foldings of the membrane of the large ulnar cell. Indeed, in some

species, the membrane of the large cells becomes striated or somewhat folded,

showing a tendency to form adventitious nervures (fig. 29). The form, direction,

2 Ff 2

220 , ORTHOPTERA.

and number of the vene oblique must thus have been determined by the knots (lines) of

the vibrations of the membrane *,

The two transverse veins (figg. 22, 23, v) must have a different origin, for they are

placed at the base of the tympanum, where the membrane is scarcely modified, and

therefore does not produce a musical sound. Their direction is precisely the opposite

to that of the true vene oblique, and two suppositions are possible: a. They might be

regarded as an extra development of two transverse venule of the reticulation [vide

fig. 18, the venule at the base of the elytron joining the v. wlnaris (diagonalis) and the

v. media]; 6. Or, they might be considered as formed by the last two (inner) vene

oblique (fig. 9, left to v) broken at right angles at their base, and rejected transversely

to the v. media, This modification must of course produce a special kind of sound.

In a general way, it may be said that the tambourine of the male elytra is a musical

instrument, each tribe of Gryllide possessing a different sort of fiddle, and that in each

tribe the genera present varieties of their typical fiddle, producing a somewhat different

note. It must therefore be admitted that the characters afforded by the musical

organ are of great importance in determining the systematic position of the species.

In the tribe Grylline the vene oblique, 2-6 and more, are obliquely transverse, and

the vene post-analis and post-axillares are arched. The genus Nemobius presents an

exception to these characters, in consequence of the small size of the species: the

tambourine is somewhat incomplete, having only one vena obliqua, which is longitudinal

and nearly parallel with the speculum, often abbreviated or obsolete.

apical valve of the ovipositor, which bears about four rough indentations and three

teeth directed upward. The facies is that of WV. vittatus, Harr., but the insect is

smaller, the ovipositor is one-half shorter and subincurved, and the lateral margins of

the pronotum are more strongly notched. The tympanum of the elytra (¢) is

regularly formed, and the posterior cells of the inner part ure elongate and parallel.

The insect is closely allied to NV. lineolatus, Duf., and N. longipennis, Sss.; but it has

the ovipositor more strongly denticulate, although much less so than in NV. araucanus,

Sss., in which the denticules form regular little spines with the ends somewhat

G. forticeps, Sauss., from Brazil, is also an allied species of pale colour, perhaps a

variety of G. miopteryx.

This genus includes numerous species, which are spread over all parts of the world.

Its members present two somewhat different types, which can be distinguished as

follows :—

1. Superior inner spur of the hind tibiw shorter than the intermediate spur, and the

apical valve of the ovipositor regularly lanceolate, as in Gry/lus.

2. Superior inner spur of the hind tibie equal to or somewhat longer than the

intermediate spur. ‘The apical valve of the ovipositor shorter, limited at the base

by a notch, principally the superior one, and terminating in a long spine; the

superior valva longer than the inferior one, the two valve more or less separated from

each other by a notch, their interior borders being sinuated. The species of type 1

are more depressed in form, and have the hind tibize longer. The species of type 2

are more cylindric in form; the females are more or less apterous, and the hind

tibiz are generally shorter in proportion. Type 2 somewhat approaches the group

Brachytrypites, while type 1 is nearly allied to Gryllus.

The systematic position of this insect is uncertain, the female being unknown. It

differs from the other Gryllodes in the elytra not having a true drum, the membrane

not being opaque and parchment-like, and the veins very irregular. Moreover, the

infra-genital plate of the male is remarkably large. If the ovipositor of the female is

rudimentary, the species should be transferred to the genus Anurogryllus.

This species is very easy to distinguish from all the other known Ectatoderi by the

‘pronotum not being strongly produced posteriorly, and but slightly attenuated ante-

tiorly, the markings of its upper surface also differing from those of the allied forms.

The shortness of the pronotum leaves the speculum of the elytra quite free, and even

the diagonal vein, which starts from its anterior angle, is partly visible.

Tribus TRIGONIDINA.

Trigonidiens, Saussure, Miss. Scient. Mex., Orthopt. p. 361; Mél. Orthopt. 6° fasc. p. 598.

The insects belonging to this group are of small size, and are very graceful and

exquisite musicians. The elytra have in both sexes the veins of the lateral field

longitudinal and simple. The mediastinal vein is not ramose, but in the males

widely separated from the humeral vein.

In all the American genera the elytra of the males are peculiarly formed and

musical, the tambourine being very complete, extending over the entire elytra, even

when the latter remain more or less coriaceous, and presenting the following

characters (Tab. XIII. fig. 36) :—

Only one oblique vein, quite longitudinal, curved, extending up to the stigma and

receiving in its middle an adventitious, longitudinal, sigmoidal vein, which starts from

the basal angle of the elytron. The axillary veins not anastomosing together before

the nodus analis. The vene post-analis and post-axillares straight or feebly curved.

The speculum elongated, rhomboidal, and presenting a concentric rhomboidal field of

the same form as the speculum, delineated by an adventitious nerve parallel to the

margins of the speculum. The vena involvens forming two narrow cells along the

hind margin of the speculum and contiguous in the middle. The apical field atrophied,

without nervures, and very narrow, membranaceous, and rounded. |

Cyrtozxiphus, Saussure, Mél. Orthopt. 6° fasc. p. 616.

Small insects, of testaceous colour. The elytra of the males large, quite

membranaceous, with the field between the diagonal and the post-anal veins usually

containing a more or less evident triangular area, this being very distinct in the species

with wide elytra and obsolete in those with narrow elytra.

The species of Cyrtoxiphus are difficult to distinguish from each other. The

principal characters are to be found in :—

1. The ovipositor (Tab. XI. figg. 39, 45) (compressed and somewhat curved). It

may be longer and more slender (fig. 43), or shorter and wider (fig. 39); in the latter

case the second half is suddenly somewhat dilated (figg. 39, 44,@). In addition, the

end of the superior margin, which is very slightly horizontally truncate (so as to form

the acute apex of the organ), varies in shape according to the species. When the

truncation is short, the obtuse angle formed by it on the superior outline (fig. 45, @) is

near the end of the ovipositor; when it is longer, it is placed at two-thirds of its

dilatation of the apical half. The pointed, cuneiform end of the organ is finely, in

gome cases more coarsely, denticulated.

2. The elytra of the males are in some species slender, with the speculum of the

tambourine rhomboidal, longer than broad; in others the elytra are very wide, and

the speculum is squarely rhomboidal, as broad as long, and the pronotum is much

dilated behind, so as to correspond with the breadth of the elytra.

In both sexes the lateral field of the elytra has three longitudinal veins and a fourth

very short one. This rudimentary vein may be placed between the two inferior

the back, is coriaceous and coloured so as to imitate the facies of Coleoptera. ‘The

left elytron remains in great part membranaceous and hyaline; the musical instrument

has been here partly lost, to enable the insect to become mimetic. Nevertheless, the

The forehead is adorned with a large black band, separated from the vertex by a

yellow line joining the eyes. The pronotum bears a yellowish line, shortened on both

sides, and other nearly lateral lines, which become fused with the yellowish margins of

the lateral lobes and with the yellowish band of the anterior margin. The colour of

the feet is very variable, passing from black to rufous. The posterior femora are at

the base pale or greenish-brown, this colour terminating in bands, the tip being rufous.

The lateral macule of the elytra are variable. |

A very musical group, characterized as follows:—The elytra of the males always

entirely occupied by the tambourine, even in the species with apterous females, in

which case they are widely rounded at the tip (Tab. XII. fig. 15). The mediastinal

PROSTHACUSTES. 241

vein very ramose. The humeral vein repulsed into the lateral field; the discoidal vein

forming the ridge, arcuate or sigmoidal at the base, leaving a rather wide lateral area

between it and the humeral vein; this area often narrowly fusiform, reticulated by

transverse nervures in the larger species. The oblique veins obliquely transverse, as in

the Grylline; the last one not anastomosed at its base to the diagonal vein by an

arch, but emerging generally from the stridulating vein, as well as from the preceding

oblique veins. The speculum large; its involving vein continuous, and the involving

area thus not divided into cells.

These insects have very complete stridulating-organs, but produce delicate sounds.

Group PHALANGOPSITES.

Phalangopsites, Saussure, Mélang. Orthopt. 6° fase. pp. 536, 543.

Elegant and light insects, with long legs, these latter allowing them to progress with

ease amongst the grass and weeds. ‘The females apterous in several American genera,

with a rounded supra-anal plate, and straight and acute ovipositor.

In the elytra of the males the vena diagonalis rarely reaches the anal knot, its base

being generally fused with the base of the post-anal vein. The speculum is frequently

wide, divided by two or more veins. In the species which have apterous females the

elytra of the males are more or less abbreviated, destitute of an apical field, but with

the apical margin deflexed downwards, and the hind wings are generally completely

wanting. When both sexes are winged the elytra are elongate, and terminated by an

apical field. (Tab. XII. fig. 4.)

In this genus the male elytra are not much shorter than the abdomen, rounded at

the tip; with a triangular speculum ; the oblique veins about four or more in number ;

the veins of the lateral field simple and longitudinal (2. e., the mediastinal vein not

ramose).

PARAGRYLLUS, Guér.-Mén.

‘Paragryllus, Guérin-Méneville, Icon. du Régn. Anim., Ins. p. 329 (1829-1838) ; Saussure, Miss.

Scient. Mex., Orthopt. pp. 430, 441; Mélang. Orthopt. 6° fasc. pp. 536, 551 (fig. xli., 1*).

A very remarkable genus, on account of the complication of the tympanum of the

elytra of the males, and by the fact that the superior internal spur of the hind tibia

is tumid and enormously large in this sex (Tab. XII. fig. 5,c). Both sexes are

completely winged; and the elytra of the males possess a well-developed unmodified

apical field. ‘Their tambourine is characterized by numerous oblique veins and by a

rounded speculum divided by numerous arched nervures (Tab. XII. fig.4). he

discoidal vein is fused at the base with the humeral vein (as in the genus Hom@ogryllus) ;

the medio-discoidal area is thus very fusiform, and also pointed at the tip.

The Paragrylli were hitherto known only from the males. I here give the description

of the females of two species, showing that the enormous spur of the hind tibiz is

peculiar to the males, the females having normal spurs, the superior one being only

somewhat incrassated, but not abnormal.

The genus is restricted to Tropical America. In addition to the two species

enumerated here, a third, P. martinii, Guér.-Ménev., is known, from the island of

Guadeloupe.

ECTECOUS, Sauss.

Ectecous, Saussure, Mélang. Orthopt. 6° fasc. pp. 537, 554 (1878).

This genus closely resembles Prosthacustes in its general facies, but differs from it

in the structure of the head, elytra, and spurs. It is easy to distinguish by the anterior

tibie being perforated at the outer side only, as in Hemicophus, which is of a slender

form with long elytra, having a very different elytral tambourine, @ ¢. the speculum

elongated *. The elytra of the males are very similar to those of Paragrylius, but

without apical field.

This insect nearly approaches E. hedyphonus, Sauss., from Brazil, the type of which

is not available for examination. The latter has the superior inner spur of the hind

tibie longer than the intermediate one, the ovipositor of the female as long as the

hind femur, and the speculum in the male more triangular. It is not unlikely that

they are varieties of the same species.

This genus is characterized in both sexes by its short corneous elytra, which are quite

polished and without veins in the dorsal field. In the males there is only a trace of a

stridulating vein. The anterior tibie present one or two drums. The inner superior

spur of the hind tibie is much the longest.

A species closely allied to A. aztecus, from which it may be known by the vertex

having a broader rostrum, especially in the males; the inferior margin of the lateral

lobes of the pronotum less straight and not oblique; and the larger, differently formed

male elytra. In A. aztecus the elytra of the males have four or five oblique veins only ;

the speculum is nearly symmetrical, its anterior margins being not very unequal; the

lateral field has only 8-12 costal veins, which are rather irregular and obsolete, and not

incrassated at the ends; the supra-anal plate is destitute of a process; and the infra-

genital plate is shorter.

A very remarkable species, on account of its enormously long and thin legs,

exaggerating the extreme forms of Arachnomimus, imitating those of the cave

Rhaphidophora. This insect might be equally well placed in the genus Arachnomimus,

the anterior tibie being often destitute of a tympanum on both sides. When an insect

takes an exaggerated aberrant form, the generic characters often show a tendency to

become more or less effaced by the effect of adaptation (the same remark applying also

to the specific characters—vide varietatem).

Endacustes, Saussure, Mélang. Orthopt. 6° fasc. pp. 537, 575.

The diagnosis of this genus requires modification :—The inner spurs of the hind

tibiee are variable in size, the superior spur being sometimes shorter, sometimes longer

than the intermediate one. In #. irrorata the superior spur is the longest; in the

Mexican species it is the intermediate one which is the longest, as in the genus

Endecous. Endacustes differs, however, from that genus in the relative length of the

outer spurs—the superior spur being the longest in Endecous, and the intermediate one

in Endacustes. The two genera are very closely allied, and might be treated as one.

This insect is very different from the Australian members of the genus. It has still

longer legs than FE. australis; the anterior and intermediate femora are quite slender,

while in E. australis they are somewhat incrassated at the base. In EL. australis the

shield-shaped area of the face is higher, and its process towards the vertex is not so

much attenuated, and more widely truncated at the top; the palpi are much shorter

and less slender ; and the elytra of the male are one-half shorter, with five or six oblique

veins, &c,

In E. irroratus the legs and palpi are much shorter and thicker; the hind femora

are scarcely linear at the apex; the process of the vertex is shorter and triangularly

truncate; the two superior inner spurs of the posterior tibie are of equal length, or

the superior is the longest ; the ovipositor is not attenuated at the tip; the elytra of

the male are much smaller, covering only half of the abdomen, and have 7-8 oblique

veins, and the tympanum is regularly triangular.

ARACHNOMIMUS, Sauss.*

Arachnopsis, Saussure, Mélang. Orthopt. 6° fase. pp. 537, 582 (1878) (nomen preocc.).

This very remarkable genus is unfortunately only known from immature specimens.

It is, however, well characterized by its very long legs. ‘The anterior tibie are destitute

of drums, as in the genus Cophus, from which Arachnomimus differs in the form of

the pronotum. The spurs of the hind tibie are like those of Amphiacustes: the

superior inner spur is much shorter than the intermediate spur, a character separating it

from Phalangopsis (another imperfectly known genus). Arachnomimus may be known

from Phalangopsis and Endacustes by the fact that the superior part of the facial shield

is broad, as in Amphiacustes, while in the neighbouring genera it joins the vertex by a

narrow process. ‘The females are certainly apterous, and the males are not unlikely

to be apterous also. These insects are most interesting as representing the cavicolous

type of the Gryllide, imitating the very slender forms of the Locustide which live in

cavesf. The genus was known only from India, but it will probably be found in

the caves of different parts of the world. ‘The name Arachnopsis being preoccupied

in Crustacea, it is necessary to change it. :

Eneopterites, Saussure, Miss. Scient. Mex., Orthopt. p. 464.

The insects of this tribe have not such light forms as the Cicanthine. Indeed, they

have a more slender appearance, the elytra not being dilated as in the Ci&canthine ;

moreover, the head is larger and the body stouter, the legs are shorter and more

robust and normal in form, the hind femora not being prolonged in a filiform shape

as in the (canthine*. The elytra of the males have a much narrower dorsal field.

Their tambourine, when present, is thus very complete, but not so delicate as in the

CEcanthine ;' and as the elytra are elongated, they are not obtusely rounded, but

terminate in a more or less pointed apical field. The speculum is variable in form—

ovate, elliptical, or rhomboidal, separated by one, rarely by two dividing veins. The post-

anal and first post-axillar veins are curved in the form of a C; the first sends a branch

to the speculum. The adventitious veins belong to the two types described, anted,

p- 212*. When the vene oblique exist, they are obliquely longitudinal, straight, or

flexuous, sometimes flabellate+; the last one anastomoses with the base of the

diagonal vein. When the vene oblique are atrophied, they are replaced by the two

vene transverse (Tab. XIII. figg. 23, 29, v), and only the arch forming the base of the

last oblique vein remains. ‘This transformation is peculiar to the tribe Eneopterine.

In several genera of this section the elytra of the males are destitute of a tambourine,

i. é., formed as in the females. In a few types the tambourine is imperfectly developed,

and the neuration of the elytra is, in consequence, very irregular and reticulated {. It

may be added that some of the genera of Eneopterine are completely winged, and

others are apterous, or have only rudimentary elytra, in both sexes. ‘The males and

females, therefore, are usually very similar in this respect, whereas in most of the

CEcanthine the males are generally more fully winged than the females.

This large species probably extends, like Eneopterus surinamensis, into the northern

parts of South America and also to Panama. The male of this genus was previously

unknown, and I have taken the opportunity of describing and figuring one here. The

tympanum of the elytra resembles that of Orocharis, Apithes, and the allied genera

(Tab. XIII. fig. 23, v,v'); but the inner nervure of the venw transverse, broken at a

right angle, is prolonged somewhat beyond the second outer branch (Tab. XIII. fig. 1).

The lateral field is reticulated at the base by transverse venule, and between them

by irregular incomplete veins.—This insect cannot be the male of P. mortutfolia, on

account of the corneous whitish callosity between the eyes. |

This very small species does not accord very well with the other members of the

genus, the vena stridulans not being broken in a zigzag at its base; but this difference

is perhaps due to the minute size of the insect, the vein not having space to assume a

complicated form. The single specimen received is imperfect.

This species is very different from the preceding. It has somewhat the facies of a

coleopterous insect on account of its convex elytra, and imitates the forms of the genus

Apithes; but its characters are quite those of Diatrypus, the vertex being narrower

than in Apithes, the elytra regularly reticulated, the hind tibiz with 5 :5 spines only,

the hind metatarsi longer and slender, and the ovipositor terminated by a short obtuse

dentated club, not pointed as in Apithes.

Carsidava, Walker, Cat. Derm. Salt. i. p. 53 (1869).

A well-characterized genus: the females by the flattened, short ovipositor (Tab. XIII.

fig. 34), the males by the interrupted zigzag stridulating vein of the elytra (Tab. XIII.

fig.9,a)7. The genus seems to be confined to Central America and the northern parts

of South America. The limits of the species are somewhat uncertain, on account of

the variability of the characters. The coloration is of but slight importance, except in

one case (P. niger), all the species being fulvous in colour, with more or less numerous

black marks on the elytra, these markings sometimes becoming obsolete. The antenne,

head, and pronotum vary in colour, the head and pronotum being sometimes brown or

chestnut-brown. The anterior tibiz have always an elliptic, membranaceous tympanum

on their outer side (instead of on the inner side, as in Orocharis). The tympanum of

the inner side assumes various forms according to the species, but it is somewhat

variable in shape. When it is very narrow and long, it can apparently be closed by the

contraction of the tibia, so as to be reduced to a ridge (this may, however, be due to

contraction after death). In some cases the inner tympanum is quite obliterated and

replaced by a superficial sulcus or by an elongate depression. It is difficult to say

whether these differences are specific or not. The ovipositor is of a special type, as in

Heterecous (Tab. XIII. fig. 34). The tympanum of the male elytra is very different

in form from that of Orocharis, the true oblique veins being well-developed, five or six

in number, elongate, longitudinal, and somewhat undulate, divided into two groups,

the last two veins anastomosing with the base of the diagonal vein and the others

issuing from the stridulating vein; while in Orocharis and Apithes there are only two

transverse veins.

Differs from P. tibialis in having the inner tympanum of the anterior tibie in the

form of an elongated depression, this being twice the length of the elliptic opening

of P. tibialis and distinctly membranaceous, not a narrow ridge as in P. aztecus.

P. foraminatus, from Cuba, appears to be nearly allied to P. olmecus, differing from it

in the more rounded posterior margin of the pronotum and the coriaceous elytra, with

polygonal reticulation and the vena mediastina more ramose.

insect resembles P. mexicanus, while P. foraminatus is of the type of P. niger, with

A very distinct species, characterized by its anterior tibie having a somewhat ovate

swelling in the middle, this being much more pronounced than in P. aztecus. The

inner margin of the swelling is somewhat in the form of a shell, overlapping the

border of the tympanum. ‘The hind femora are feebly developed, and the inner

spurs of the posterior tibiz are short. In P. aztecus the inner spur of the hind

tibie is half the length of the metatarsi. In size and facies P. podagrosus resembles

P. tibialis and P. niger.

A very distinct species, owing to its slender legs and regularly, not densely reticu-

OROCHARIS, Uhler.

Orocharis, Uhler, Proc. Ent. Soc. Phil. ii. p. 544 (1864); Saussure, Miss. Scient. Mex., Orthopt.

pp. 466, 492; Mélang. Orthopt. 6° fasc. pp. 647, 749.

This genus includes numerous species which are all very closely allied and difficult

to separate, particularly in the female sex. The males present better differential

characters—in the venulation of the drum of the elytra, the characteristic veins of this

organ showing distinct variation in form according to the species, principally in the

stridulating vein, which is either transverse (Tab. XIII. fig. 22.4) or oblique and

bisinuated (Tab. XIII. fig. 23). The speculum is also more or less elongate, but less

characteristic, it being rather variable in different specimens of the same species; its

anterior angle receives a branch of the postanal vein, which makes it somewhat

truncate, except in one known species, in which the little anal branch anastomoses

with the diagonal vein instead of reaching the angle of the speculum.

The species differ a little in size. They are all of a fulvous-greyish colour.

It is probable, however, that in life these insects are often of a whitish-green

colour, as in the genus Gcanthus, but not in all specimens, greyish varieties being

frequently found in living specimens, as they are, for instance, in Mantide. Generally,

the legs are dotted with reddish-brown, but these slight differences of coloration are

of no importance.

The anterior tibia have an elliptic tympanum on their inner side, and, generally, a

smaller tympanum on their outer side. The inner drum, examined by transparency,

appears as if divided by a longitudinal opaque line; the outer drum is sometimes

obsolete. In this respect the genus Orocharis differs from Parecanthus, the latter

having the principal drum on the outer side of the tibia and the inner perforation often

more or less closed. The mobile spines of the hind tibiz are more or less numerous,

and not very characteristic.

very abundant, especially in Central America and the Antilles.

This species resembles 0. conspersus, Sss., from Brazil, but it is smaller and has the

apical part of the vertex truncate and convex, not sulcate; the neuration of the male

elytra is also different, the postanal vein being strongly arcuate and its branch not

falling on the inner end of the speculum, but joining the vena diagonalis before this

angle; and the speculum is very elongate and ovate. The neuration of the tympanum

(‘‘ vena stridulans et v. oblique supplementares”) resembles that of O. conspersus, and

these two species form, on this account, a particular group.

The genus Orochirus is closely allied to Apithes and Orocharis, the tambourine of the

male elytra belonging to the same type and the anterior tibie having a large tympanum

on their inner side. It differs from these genera, however, in the following

characters:—the surface of the head, pronotum, and legs is somewhat wrinkled and

strongly pubescent (not even and shiny, as in Apithes and Orocharis). The apex of

the vertex is more elongate. ‘The ocelli are placed in a triangle, not in a transverse

278 ORTHOPTERA.

arcuated line. The femora and the intermediate tibie are so much compressed as to

be nearly lamellar; the posterior femora are not clubbed at the base. The genicular

lobes of the anterior and posterior tibie are sometimes produced. The elytra are

elongated: in the females rough and irregularly reticulated ; in the males produced

into a long apical field, and with a rhomboidal speculum, which is narrower and more

elongate than in Apithes and Orocharis. The males are sometimes depressed.

These insects are generally of a grey colour, with black dots and stains. The genus

seems to be peculiar to Central America and the Antilles.

I regret to have to propose this new genus. ‘The two species referred to it might be

included in either Anaudus, Sauss., or Podoscirtus, Serv.; but the ovipositor, instead of

being long, slender, and cylindrical, is short, depressed, and sublamellar, with flattened

apical valve, as in Parecanthus and in Stenaphonus, belonging, in fact, to a very different

type from either Anaudus or Podoscirtus. As I suppose the males have no drum on

the elytra, I place Heterecous amongst the non-musical Podoscirtites, in which it forms a

little group with Metripus and Stenaphonus, on account of the form of the ovipositor,

but distinct from that genus by the anterior tibie being perforated. Its position can

only be fixed with certainty when the males are known.

LOCUSTIDA.

Fam. LOCUSTIDZ *.

This large family has been divided by Brunner von Wattenwyl into numerous

subfamilies in a very natural way. It differs from the Gryllide in the four-jointed

tarsi (the tarsi of the Gryllide having three joints only), and in the form of the

stridulating-organ of the males, which, when present, is much reduced and confined to

the anal field of the elytra.

The Gryllacrine and Stenopelmatine form in the family Locustide a separate section,

presenting a kind of link to the Gryllide. Indeed, in these two tribes the elytra

are still, as in the Gryllide, divided into two fields—a lateral and a dorsal field,

this latter being formed by the fusion of the discoidal and anal fields. But in these

insects the two fields are not so well separated as they are in the Gryllide; and the

elytra being more or less membranaceous they mould themselves, when at rest, on the

body of the insect, becoming somewhat convex on the back, and forming a sort of

cylindrical case to the abdomen. ‘The venulation of the elytra has also some analogy

with that of Gryllide, all the longitudinal veins being well separated from their base,

which is not the case in other tribes of Locustide.

The Stenopelmatine are mostly apterous insects, very few of the species belonging

to it being furnished with wings.

The males are destitute of a musical organ in the elytra; nevertheless many of the

species possess tympani on their anterior tibie in both sexes, which proves that these

insects stridulate in some way. Brunner von Wattenwyl has shown that musical

excellent work forms a very complete monograph of the Stenopelmatine and Gryllacrine, and we have

followed it throughout. Several of the synopses of species here given to help the identifications have been

sounds are produced by the rough surface of the inner base of the hind femora rubbing

against the short elevated ridges or rugosities on the first segment of the abdomen.

This apparatus is similar to that of a portion of Acridiide, especially of the Eremobiine

and of some Pamphagine *,

We find in the tribe Stenopelmatine two very different types, as in Gryllide:

a fossorial type, with heavy forms, short robust legs, and strongly armed tibie

(Tab. XIV. fig. 1); and a terrestrial type, with lighter forms and long legs (Tab. XIV.

figg. 12, 19, &c.). The latter do not appear to live so much amongst the grass and

bushes as the Gryllide ; they cannot leap very well, but are good runners.

antenne, this being called by us “ rostrum verticis.” In the diagnoses which we have been obliged to take

from the works of this author (as we have seen no specimens of the species) we have preserved his nomenclature.

The anal pieces in the males of the Locustide are very complicated in structure and

require a long study before they can be compared and homologized in the various

species. The enclosing piece here described must be considered as the penis. Its

inferior part is very distinct as such in Glaphyrosoma, in which it is elongate, thick,

and rounded. In Pherterus this part appears to be lamellar and chitinized (the real

structure, however, can only be made out when fresh specimens are available for

* They may be distinguished as follows :—

Puerrervs.—Inferior margin of the lateral lobes of the pronotum arcuate. Infra-genital plate of the

females rounded. Supra-anal plate of the males (10th abdominal tergite) very short, notched. Anal

appendages ( d ) not apparent.

Giapayrosoma.—Inferior margin of the lateral lobes of the pronotum straight. Infra-genital plate of the

females triangular, acute. Supra-anal plate of the males concealed under the 9th abdominal tergite. Anal

appendages large.

examination). The small superior reflexed acute-triangular lamella, which closes the

anus from below, is only a sort of appendage of the base of the real penis. The

homologues of these pieces may be found in other Locustide, ¢. e. in Decticus, in which

genus the penis forms a thick rounded fleshy mass, divided in superimposed lobes, and

presenting at the base a sort of separate part, which, when removed, appears as if

formed of two lobes, with their inner margins chitinized and black. The superior

reflexed lamella in Pherterus and Glaphyrosoma must be the homologue of this basal

mass. In different Phaneropterine there is also at the base of the penis a sort of

pyramidal tubercle, which is probably another modification of the same part.

Phoberopus belongs to the same group as the African genus Onosandrus, if we follow

the method of Brunner von Wattenwyl; but it forms a section characterized by its

posterior metatarsi being completely flattened and membranaceous beneath (sulcated

in dried specimens), with their inferior face remarkably wide, and occupied in their

entire length by a single pulvillus, instead of by two pulvilli as in the allied genera.

The general form of these insects is like that of Udeopsylla, with short thick

posterior femora, not narrowly prolonged at the apex ; but they resemble Ceuthophilus

in having the anterior tibia unarmed on the upperside, the intermediate femora with a

genicular spine, the intermediate tibiee with two spines above on their upper posterior

margin (not two on each margin, as in Udeopsylia), the posterior tibiz rounded and

unarmed, beneath furnished at the tip with long spurs (of which the intermediate are

much longer than the superior ones), and the posterior tarsi carinated beneath.

The genus might be regarded as forming only a division of Ceuthophilus. In any

case, the name Hemiudeopsylla ought to be retained for H. genicularis, which is a very

peculiar type.

The insects of this section are remarkable on account of the development of their

wings, ‘The elytra are generally long, the wings wide and rounded. The former are

membranaceous, and their venulation very complete and evident, the longitudinal

nervures being well separated from each other in their entire length, and very easily

distinguishable. In consequence, the neuration of the elytra is far from being so

characteristic as it is in the Grylline.

The Gryllacrine are certainly related to the Grylline, but, taken as a whole, they have

greater powers of flight; yet they present also, like the Grylline and the Stenopelma-

tine, a fossorial type. This is found in the genus Schizodactylus, a most extraordinary

insect, imitating in form and appearance a large Gryllus, the elytra resting flat on the

back, with the lateral field deflexed perpendicularly on the sides and separated from

the dorsal field by a sharp ridge. This type forms an evident passage to the Grylline

by its general facies, although the positive characters and the venulation of the elytra

are those of Gryllacrine, and generally it is the left elytron which in rest covers the

right one, as in other Gryllacrine ; but these insects (like the Grylline) can place at

will either elytron uppermost.

The Gryllacrine are not musical insects. The males possess no tambourine on the

elytra, and neither sex has tympani in the anterior tibia. The elytra in repose rest on

the dorsum of the abdomen, and they seem to be too long and too membranaceous to

support a tambourine, unless very small and basal. In the genus Schizodactylus one

certainly might have been developed and extended to the whole elytra, these organs

being flat and somewhat coriaceous; but as the elytra are curled up together at their

extremity, it is impossible for one of them to rub on the other.

The Gryllacrine, numerous in the Old World, include but few genera, and they do

not seem to be very abundant in Central America.

* In Brunner’s synopsis of the species of the genus Gryllacris two errors occur in the text (p. 82) :—

6, 6. (Species Americanz, &c.) Instead of “ femore postico duplo longior” read “ sesqui-longior,” or “ viz

sesqui-longior.”

7. (Caput &c.) Instead of “ femore postico sesqui-breviore” read “ femore postico sesqui-longiore.”

These corrections must also be made in the descriptions of the species, as proved by the measurements given

by the author.

This very fine and distinct Gryllacris is intermediate between G. levigata and

G. cruenta, Brunn., from the Upper Amazons. In coloration it nearly approaches

G. cruenta, which also has the nerves of the elytra rose, but the spines of the feet are

not black, as in that species. The anal pieces resemble those of G. levigata, Brunn.

(Monogr. der Stenopelm. und Gryllacr. p. 97, t. &. fig. 41.c), but they have much

longer styles, and the venule of the elytra are not black. The infra-genital plate is partly

destroyed in the only specimen obtained, and its shape cannot be described.

The Phaneropterine constitute a special type of Locustide. They have the elytra

more or less coriaceous, occupying a particular position, being placed when at rest on

either side of the body in a somewhat perpendicular plane, uniting together on the

back by their inner (sutural) margin, in the form of an acutely angled roof. This

position is due to the discoidal field being here fused in a single plane with the

marginal field, and thus becoming lateral, contrary to what obtains in the Gryllide,

where the discoidal field fused with the anal field has become dorsal. Thus in the

Phaneropterinz the anal field alone remains dorsal; but it is much reduced, making,

when the elytra are at rest, a small basal field of lanceolate form.

The elytra overlap in their small dorsal field only, and, in contradistinction to what

happens in the Gryllide, it is the left elytron which covers the right one, this being

the natural position of the elytra in Locustide. The lateral and the dorsal fields are

separated nearly at a right angle by an acute ridge, which is formed by the posterior

(second) ulnar vein, this vein being continued all along the sutural margin of the elytron.

t Nomenclature.—Brunner v. Wattenwyl designates under the term fastigium verticis the anterior apex of

the vertex between the antenna. This part we have always named rostrum verticis, principally when it is

narrow, but we retain the terms used by Brunner v. Wattenwyl when we reproduce any of his diagnoses.

The same author has adopted the nomenclature of St&l for the elytra, giving the name ven radiales to

the three nervures we designate by the terms vena humeralis, v. discoidalis, and v. media. We have no

reason to change our nomenclature adopted from the beginning and which applies to all the families of

Orthoptera. It must be noticed that in the Phaneropterine these three veins are fused together at the base,

especially the vena media, which issues from the middle of the discoidal vein as if it was a posterior branch of

that vein. In St&l’s nomenclature this vein corresponds to the vena radialis posterior, Brunner y,

Wattenwyl! calls it ramus posterior vene radialis. We call it vena media so as to respect the homologies in

the nomenclature.

PHANEROPTERIN 2. 311

The nervures of the elytra are very simple and similar in both sexes. The vena

mediastina is very short and often effaced. The vene@ humeralis and discoidalis are

contiguous, at least in their proximal part, slightly divergent in their distal part. The

discoidal vein, somewhat arcuated and subsigmoidal, is the principal one; it divides

the elytron longitudinally into two fields. The vena media is fused at the base with

the discoidal vein, and escapes about the middle, and is most frequently furcate. The

anterior vena ulnaris is straight, terminating on the sutural margin. ‘lhe dorsal field

is coriaceous, punctured, or reticulated. ‘This field, being the musical part of the

elytron, requires special attention.

The typical dorsal field must be described from the females, it being unmodified in this

sex. It presents three veins: the anal vein, longitudinal and parallel to the ridge, and

two axillary veins, very feeble and frequently effaced. The second axillary vein, starting

from near the extreme base of the anal vein, is at first transverse, then breaks at an

obtuse angle to become longitudinal, more or less parallel to the sutural margin of the

. dorsal field, and runs to near the end of the field to fuse with the end of the anal

vein. The frst axillary vein is contiguous at the base with the anal vein; it diverges

from this in its middle to become obliquely longitudinal, and anastomoses at its

extremity with the second axillary vein, delineating with this vein an elongated triangle.

In the females the dorsal field is generally very similar in both elytra and coriaceous,

except that the right elytron presents often along the sutural margin a more or less

wide membranaceous hyaline band longitudinally divided by the second axillary vein.

In the larger species (principally in the Steirodontites) this band is strongly reticulated

by transverse venules. We do not consider, however, that this membranaceous part is

to be regarded as a sort of stridulating tambourine ; probably it has lost its coriaceous

nature through being covered and protected by the left elytron when at rest. Never-

theless, it should be mentioned that in the large species the second axillary vein, which

divides or limits the membranaceous area, as well as the transverse venule impinging

upon it, are very thick and prominent, as if modified for a special purpose.

Musical organ.—The males of the Phaneropterine are all musicians, except those

with rudimentary elytra; but as the musical organ is confined to the small dorsal

(anal) field it is much less developed than in the Gryllide, and is far from furnishing

such clear characters for classification as in that family. On the contrary, it. is very

similarly formed in all the genera of this group, and varies principally in having the

nervures more or less fused in the coriaceous reticulation of the dorsal field.

’ The modifications of the latter to form the tympanum are somewhat analogous to

what I have described in the Gryllide, but the tympanal field being very narrow, the

stridulating vein cannot be formed by the anal vein; it is the first axillary vein which

is here transformed for that purpose. There are only two axillary veins, both much

thickened and deflexed, but not in the same way on both elytra, the tambourine of the.

312 ORTHOPTERA.

left elytron being differently formed from that of the right elytron, whereas in the

Gryllide the two tambourines are similar. Indeed, the two elytra are not alike in

structure, this being due to the left elytron covering the right one in repose, and to

their having different functions.

The neuration of the males is as follows :—

Ist. In both elytra the anal vein is unmodified, straight as in the females.

2nd. Left elytron.—The jirst axillary vein is nearly straight, as in the females; but

it emerges from the anal vein earlier than in that sex, and emits an inner branch, the

latter being broken at aright angle, becoming quite transverse, and very much thickened,

swollen above, and bordered posteriorly by a deep furrow. This transverse tumid

nervure is the stridulating vein. Beneath it is very prominent, longitudinally sulcate,

and transversely strigose, to produce the stridulation by rubbing like a file upon the

right elytron. This enormous transverse vein is the fiddle-bow of the musical apparatus.

The first axillary vein, after having furnished the stridulating vein, continues back-

wards in a longitudinal direction, and is very fine, as in the female, its post-axillary part

appearing thus to be a special vein (which may be called the first post-axillary vein).

The second axillary vein originates near the anal vein; it is at first strongly trans-

verse and prominent, but becomes oblique to anastomose close to the sutural margin

with the inner end of the stridulating vein, enclosing with this a convex, piriform,

coriaceous, punctured area, which is certainly sonorous*. It is thickened to support

the stridulating vein, and is frequently divided into two parallel branches. The angle

by which the second axillary vein joins the stridulating vein might be compared to the

anal knot of the tambourine of the males of the Gryllide f.

The second axillary vein, after having joined the end of the vena stridulans, runs

back outwards, and becomes transverse, parallel to the stridulating vein, and only

separated from it by the transverse sulcus, and anastomoses ata right angle with the

straight external branch of the first axillary vein. ‘The second transverse vein, thus

formed, is generally stout and thickened, but not so much as the stridulating vein;

from above it appears as a second stridulating vein, but it is not prominent beneath

and serves only as a strong support for the stridulating vein. Frequently it is

not distinct, but fused with the latter; in consequence, the left dorsal field shows

either one or two transverse veins.— The second transverse vein sends from its

middle backwards a thin longitudinal nervure (2° vena post-axillaris t), which joins in

* The two axillary veins are here disposed very much as in the male Gryllide (comp. Tab. XIII. fig. 22, x, w’').

t The two axillary veins modified and anastomosed form together what Brunner v. Wattenwyl terms the

vena plicata, This expression, although not based on homologies, is often very convenient for the diagnoses of

species. °

+ This vein is the posterior, unmodified and fine end of the second axillary vein, and is less prolonged than

in the females. It looks like a branch of the second transverse vein or of the stridulating vein ; but, in reality,

it is the second transverse vein which is formed by a branch of the second axillary vein.

PHANEROPTERIN &. 313

an acute angle the end of the first post-axillary vein, forming with it an elongated

triangle, homologous with the angle formed posteriorly by the two axillary veins, in the

females, but not so much prolonged.

This triangle is useless for the production of sounds; it is only a homologue of the

normal veins of the female elytron; it may be called the post-axillary triangle, its

margins being formed by the two post-azillary veins *.

We have thus shown that the males of the Phaneropterine have in the left elytron

a very powerful stridulating-organ, this being strongly coriaceous and supported by the

whole dorsal field.

3rd. Right elytron.—The veins are not so strongly deflexed as in the left elytron. The

Jirst axillary vein is well separated from its base from the anal vein, and longitudinal,

as in the females, but frequently flexuous and much stronger; it emits an obliquely

transverse stout branch, sometimes greatly thickened at the base. This nervure is the

homologue of the stridulating vein of the left elytron, but it is often divided into two

parallel branches, imitating the two transverse veins of the latter. Beneath, the first

axillary vein is. not very prominent, showing that it is not a fiddle-bow, as in the left

elytron. Behind this transverse vein we find the post-axillary triangle, as in the left

elytron, but bordered with strong veins.—The second axillary vein is at the base

obliquely transverse (in the rest of the elytron appearing quite transverse, parallel to

the hind margin of the pronotum ), and then becomes longitudinal and divides into two

parallel branches, which are much thickened and prominent and submarginal to the

sutural border, terminating in a sort of notch in the latter. The two thick branches

serve to consolidate the corneous margin, which forms the sonorous area (alex, comp.

anted, p. 218) on which the stridulating vein of the left elytron rubs to produce

the tunes, and they must be considered as the two strings of the fiddle.

The post-axillary triangle is similar to that of the left elytron, but not quite

symmetrical with it; its inner margin is formed by the second portion of the second

axillary vein, this being much thickened, broken off, and quite separated from the

first portion f.

The tympanal field of the right elytron is thus divided into several compartments :—

1. At the base, the large axillary cell, generally convex, coriaceous and punctured, as

in the left elytron. 2. Outside, the elongate ano-axillary cell, partly membranaceous

and hyaline (outer speculum), except at the base. 3. The triangular (post-axillary)

area, also membranaceous (inner speculum). The second and third cells form the

tambourine of the elytron.

At the posterior extremity of the triangle the veins become greatly reticulated,

* Homologous with the first two post-axillary veins of Gryllidw. (Comp. anted, p. 217.)

+ This anomaly is due to adaptation. The first part of the second axillary vein has become independent

to form the marginal strings, next to the illev, and thus the post-axillary triangle is separated from it.

enclosing small hyaline cells. The remaining parts of the dorsal field, 7. ¢. the apex,

inner and outer margins, are more or less coriaceous and green in colour *.

The conclusion to be drawn from this analysis is that the left elytron is the fiddle-

bow of the musical instrument, and that the right elytron is the tambourine which

produces the sounds. |

The musical instrument is here very simple as compared with that of the Gryllide,

and, on account of its rougher surface, must certainly produce less varied and less

musical sounds. . .

Hind wings.—These present at the base of the posterior field two strong transverse

veins fusing together in an acute angle. The anterior vein is somewhat. oblique;

the posterior one is transverse and formed by the heads of the radiate nervures of

the hind field anastomosed together into a chitinous arch, which forms a support

for them.

This sort of vein, in the shape of a V, might be termed, following Brunner v.

Wattenwyl, the vena plicata; but it is not homologous with his vena plicata of the

tympanum of the male elytra (comp. anted, p. 312, notef), for it has not the same

position, and, besides, its angle is turned in a contrary direction (the angle outside,

instead of inside), and, in addition, it is found in both sexes. Moreover, such a vena

plicata exists also at the extreme base of the elytra, near their articulation ; but it is

very small and not always evident, its separate parts being frequently disunited.

The Phaneropterine live mostly in bushes and on trees. They are all mimetic

insects, their oblong, ovate, or lanceolate elytra, placed in a perpendicular plane,

exactly imitating leaves. Most of them are green in colour; others are variable in

this respect, green or brownish, imitating living and dead leaves, perhaps according to

the season. They fly very readily. In all the known Central-American genera (except

Dichopetala, 2 ) the elytra and wings are completely developed.

* The appearance of the musical field as we have described it is rarely evident, the whole of the veins being

seldom developed in a normal manner. They are frequently fused together by becoming thickened or inter-

rupted for the purpose of forming the tympana.—In the left elytron, the second axillary vein, instead of joining

the inner end of the stridulating vein, is often interrupted at its angle, so that the second transverse vein

seems to be independent. In both elytra, too, the normal venulation is often considerably modified by the

extension of the coriaceous reticulation of the dorsal field. In the right elytron the tambourine when invaded

by such reticulation is no longer apparent and is reduced to a less musical instrument. What we have

endeavoured to do is to describe the theoretic typical structure of the musical field, based on its homologies

independently of the various appearances which it may present.

CHLOROSCIRTUS, gen. nov.*

Verticis rostrum angustum, valde sulcatum, apice clause acuminato-hebetatum, cum fastigio frontis hand

contiguum. Frons rotundata; fastigio lanceolato, hebetato-acuminato. Pronotum disco plano, canthis

dato. Lobi laterales altiores quam latiores, margine infero et postico arcuato. Mesosterni lobi trigonales ;

media sulcate, supra mutice, subtus spinulose ; antice supra spina apicali nulla, basi utrinque tympano

aperto ; infra foramina valde attenuate, gracillime. Tibis intermediz supra margine postico spinulis 1-2.

-Femora postica parum elongata, in parte apicali linearia, subtus utrinque spinulosa; lobi geniculares

haud acuti.

3 do. Segmentum anale margine postico sinuato; angulis productis, appendicibus minutis instructis. Cerci

teretes, arcuati. Lamina infra-genitalis carinata, apice biramosa ; ejus rami stylis longis instructi.

This genus is nearly allied to Plagiopleura, differmg from it in having the eyes

somewhat ovate; the metasternal lobes not separated by a triangular notch; and the

median vein of the elytra not straight and not reaching the tip. Chloroscirtus might be

placed next Parableta, the median vein of the elytra being directed, as in that genus,

to the hind margin of these organs.

In its general facies Chloroscirtus resembles Scudderia, but differs from that genus in

having the vertex not contiguous to the forehead. ‘The males may be distinguished

from those of Scudderia by the existence of long styli on the infra-genital plate. In

‘both sexes the elytra are more attenuate towards the end, and the tip therefore is

more narrowly rounded.

Obs.—When the styli are broken off, the males might be mistaken for the same sex

of Scudderia.

cerci magnified.

Hab. Guatemata, Duefias (Champion).

When the styli are broken off, the present species might easily be confounded with

Scudderia forcipata (infra, p. 332), which has a very similar infra-genital plate; but

the ends of the branches of the infra-genital plate appear to be finely notched, with

the inferior angle triangular and compressed, while in S. forcipata the ends of the

branches of the forceps are attenuated and rounded.

‘The members of this genus are spread over North and South America, most of the

northern forms extending into Mexico. The southern representatives are generally

of larger size. The males of the various species are easily separated by the form of

the anal plate, but most of the females are very similar to each other. The dorsal

field of the males is broadly reticulated, often hyaline in the cells; in the right elytron

its reticulation is mostly subhyaline. The ovipositor of the female varies in its breadth

and curvature, though differing slightly in form according to the species.

In the males of this genus the tambourine of the elytra is somewhat characteristic,

but its structure is difficult to define. In some species there are, in the left elytron,

two transverse elevated parallel veins, and in addition to these veins the tympanal field

presents, besides the dense reticulation, a wide reticulation, formed by flexuous nervures

(A. oblongifolia, A. uhleri, A. rotundifolia). In other species there is only one

transverse (stridulating) vein (A. tepaneca, A. guatemala).

This species is larger than P. ovata and smaller than P. conspersa, from both of

which it differs in its narrower and regularly elliptic elytra, their hind margin less

curved. ‘The hind femora are usually more or less spinose beneath, sometimes nearly

unarmed.

Obs.—A female specimen presents a curious monstrosity: the right hind femur bears

on its middle the rudiments of a small hind leg, consisting of the end of an imperfectly

formed femur, a tibia, and a four-jointed tarsus,

In this genus the tympanum of the males is generally well formed in the left elytron.

The two axillary veins (vena plicata, Brunn.) are much elevated, forming together an

acute angle. The two post-axillary veins, also prominent, do not unite together in an

acute angle, but are longitudinal. The post-axillary area is closed posteriorly by a

transverse or oblique vein, so that this area instead of being triangular is more elongate-

trapezoidal (sometimes opened and reticulated posteriorly, or variable); it is often

divided by a transverse oblique vein. The tympanum of the right elytron is more or

less coriaceous.

This species is very like C. peruviana, but it is larger and has more dilated elytra ;

and the apex of the vertex is in the shape of an obtuse triangle produced into a

compressed lamella before the ocelli, while in C. peruviana it is but little compressed.

In the last-mentioned insect the lateral lobes of the pronotum are shorter and wider

than in C. azteca, as broad as high, with the inferior margin anteriorly obliquely

truncated ; and the ovipositor is longer, it being two and half times the length of the

pronotum. ‘The cerci of the male are very characteristic in form in the present species,

the lamina infra-genitalis being wide, in the shape of a mitre, terminated by two short

triangular lobes; and the femora are not spinose.

In the allied C. peruviana, Brunn., the elytra are less rhomboidal than in the present

species, their anterior margin being straight at the base and much more curved beyond

the middle; the pronotum has the posterior margin transversely arcuated (instead of

angular), and the anterior part of the inferior margin of the lateral lobes obliquely

straightened, so as to form a distinct obtuse angle with the anterior margin; the infra-

genital plate is not prolonged, but transverse, its hind margin forming a subacute

angle; and the cerci are shorter, curved in the form of a C, and rounded at the tip.

C. foreli also nearly approaches C. zetterstedti, Brunn., but it has the anterior margin

of the elytra less curved and the posterior margin not arcuated in its proximal half;

the cerci of the male are not bimamillate at the tip, and the infra-genital plate is

very different in shape. |

Hyperphrona, Brunner v. W. Monogr. det Phaneropt. p. 315; Additam. p. 163.

Differs from Phylloptera in having the lateral lobes of the pronotum as wide as they

HYPERPHRONA. 349

are high (in Phylloptera they are narrower than high); their anterior margin is some-

what sinuated in both genera.

Obs.—The length of the hind femora relatively to, that of the elytra, of the inter-

mediate tibie to that of the pronotum, and of the ovipositor to that of the pronotum,

must be exactly compared, these proportions being characteristic of the species.

This species is well characterized by the peculiar shape of the male cerci. The anal

segment is produced between the cerci almost in the form of a truncate triangle,

less widely truncate than in 7’. ocularis. In the tympanal field of the left elytron the

two postaxillary veins are angulated inwards, and do not converge posteriorly, forming

an open triangle.

strongly reticulated, divided by a stout longitudinal vein, and has small hyaline cells.

In the females the dorsal field of the right elytron is partly membranaceous within,

divided by a strong vein (2nd axillary), which is pectinated with transverse venule,

tomewhat as in Stilpnochlora.

A very peculiar species. The female resembles W/. lanceolatum and its allies, but has

a narrower vertex and forehead, and the ridges of the pronotum are more distinct, not

obliterated anteriorly, nearly as in M. triangulatum (which has a much broader

pronotum, narrow vertex, small ocelli, &c.). The male is somewhat different, it having

the apex of the vertex deflexed downwards and bearing a fine sulcus; nevertheless, we

cannot separate it from the female. |

the ulnar vein. |

Long. corp. 82; pronot. 9; elytr. 44, lat. 15; femor. post. 25 millim.

Hab. Panama, Bugaba (Champion).

This species has some of the characters of MW. retinerve, but the vertex is broader,

not inclined. In I. retinerve the pronotum is marked by two strong sulci cutting

the edges; the elytra are much more reticulated, more membranaceous, not hard and

polished ; and the spines of the hind femora are not so strong as in M. championi.

The present insect is also very closely allied to M. punctifrons, but it is larger; the

forehead and pronotum are not strongly punctured; the venulation of the elytra is

different, the median vein having the second branch anastomosed at its angle with the

ulnar vein ; and the pronotum has rather more acute edges, its anterior margin having

a sort of tooth. From Jf. concisum it may be distinguished by the narrower vertex.

In this species the tympanal field of the left elytron of the male has three transverse

veins, and the postaxillary triangle is membranaceous and reticulated on its inner side.

Specimens of the variety 6, of median size, may be easily confounded with M. reti-

nerve, as they have the middle of the anterior margin of the pronotum not or scarcely

produced. Nevertheless, it is not difficult to distinguish them from that species, the

females having the inferior valve of the ovipositor truncate at the tip and the males

having very slender and short styli, while in J. retinerve they are long and thicker ;

moreover, in both sexes, the pronotum is flat, with the lateral ridges very slightly

interrupted by the anterior sulcus, while in J. retinerve the superior face of the

pronotum is transversely canaliculated by two wide shallow sulci, and the Jateral ridges

are rather strongly cut by the anterior sulcus.

is nearly allied to MW. erosum, Brunn., from the Upper Amazons, but may be distin-

guished from it by the spinose hind femora.

Group STEIRODONTIITES.

Steirodontia, Brunner v. W. Monogr. der Phaneropt. p. 356.

This group includes the largest species of the tribe Phanopterine, in which the

dorsal field of the male elytra presents the most typical characters (cf. anted, p. 312).

In the females the dorsal field of the right elytron has its inner margin hyaline, limited

or divided by a stout longitudinal vein, and pectinated by thick transverse venule ;

outside the longitudinal vein it is closely reticulated, with more or less hyaline cells.

On the right elytron the speculum is large and membranaceous. The ulnar vein of

the wings often bears four branches.

This species is remarkable on account of its wide form. The pronotum is broad

above, rather short. The elytra, also, are shorter and more rounded than in the other

species of the genus; they are two and a half times the length of the dorsal field,

while in S. tolteca they are more than three times as long as the dorsal field; the

dorsal field is elongate. In the form of the pronotum this species makes a sort of

transition to 9. incisa; but in the latter the margins of the anterior lobe are very

strongly trilobed, while in S. ovalifolia they are only feebly cut by numerous small

sulci, and much less strongly crenulated than the margins of the posterior lobe. ]

This is the largest species of the genus. It is distinguished by the crests of the

pronotum, and by its very wide and obtuse elytra, these latter being much wider than

in P. citrifolius, L. The wings are shorter than the elytra, and in repose do not extend

beyond them; they are obtuse (not acuminate) at the tip. P. validus is closely allied

to P. stali, Brunn., from Brazil, but the anterior tibie are without spines.

In this tribe the elytra when at rest are placed as in the Phaneropterine, but they

are generally narrow and elongate, with less characteristic veins. In the female the

dorsal field is coriaceous, with the veins usually more or less obliterated. Normally

there are visible, in addition to the anal vein, one or two regular longitudinal axillary

veins. In the males we find a tambourine much as in the Phaneropterine (comp.

anted, p. 312).

In the left elytron (Tab. XIX. fig. 33) there is a stout transverse stridulating vein (A),

sometimes much swollen and polished, attenuated towards the inner margin. Behind

this vein there is a post-axillary field (s), in the shape of an elongate trapezoid; this

field is limited at the base by a strong transverse vein (z'), which often has the appear-

ance of a second stridulating vein, as in the Phaneropterine (comp. anted, p. 312).

Generally, the whole dorsal field is coriaceous, but in some genera the external and

central cells become membranaceous and form a regular tambourine as in the right

elytron (e. g., Exacentrus, Copiophora, &c.).

In the right elytron (Tab. XIX. fig. 34) the stridulating vein (A) is less strong than

in the left elytron. The post-axillary area (s) is membranaceous and forms a brilliant

speculum. The remaining cells of the middle part of the dorsal field are also frequently

membranaceous, especially the ano-axillary cell (external speculum) (e).

The following description of figures 33 & 34 will give the explanation of the

homologies of the male tambourine of the Conocephaline (comp. anted, p. 312) :—

Figures 33 & 34 represent the basal part of the dorsal (musical) field of the elytra

of Copiophora cultricornis. This species is selected for Aguring because it has a

membranaceous tambourine in both elytra.

Left elytron (fig. 33).—The ridge separating the dorsal from the lateral field is

represented by the line w, formed by the ulnar vein. Inward of this, we find the

straight and fine anal vein (a). The jirst awxillary vein (x) which follows is fine at

the base and soon bifurcates. Its inner branch becomes transverse and is much

swollen to form the stridulating vein (A); its outer branch continues and forms the

post-axillary vein (z) (the outer or first post-axillary vein which anastomoses in uw with

the anal vein; a). Starting near the base of the elytron, we also find the second

axillary vein, which is double (a’, 2"). This is strongly transverse: its two branches

often become fused into one (0) and separate again, as shown in the figure; but they

are always united on the inner margin and with the inner end of the stridulating

vein (A), to afford the latter a solid support (which in the Gryllide is named the anal

or musical knot (n)) (comp. anted, p. 217). The second axillary vein (2", x’) after its

fusion in the anal knot curves outward and becomes more or less parallel with the

CONOCEPHALIN &. 370

stridulating vein A, forming the vein z’, and anastomoses with the first post-axillary

vein (z) next to e. (Its direction is indicated by the punctured line.) Moreover, it

bifurcates in 6; its inner branch (z2”) forms the second post-axillary vein, which

anastomoses with the first post-axillary vein (z), so as to close the central cell (s).

This cell is the principal (central or inner) drum ; it is also called the central speculum

when it is membranaceous. The elongate cell (e) which remains between the anal vein

and the first axillary vein is often. also membranaceous, and forms the outer drum or

speculum. The short vein (¢) is only a connection to solidify the stridulating vein and

the whole frame of the stridulating apparatus.

fight elytron (fig. 34)—The right tambourine is covered by the left one, and is

generally more membranaceous. Its venation is also more modified to form the ¢lez (1),

on which the stridulating vein of the left tambourine is rubbed to produce musical

sounds. On the outer side we find unmodified veins as in the left elytron, the ulnar

vein (w) forming the dorsal ridge and the anal vein (a).—The first axillary vein (2)

is more oblique than in the left tambourine; its post-axillary portion (z) forms an

angle with its basal portion (x), so that the outer speculum (e) is wider than in the left

tambourine. The inner branch (A) of the first post-axillary vein is less transverse than

the stridulating vein of the left tambourine. Moreover, the two branches of the second

axillary vein do not fuse with the stridulating vein so as to form the anal knot (4)

as in the left elytron.

There is, in fact, no anal knot; and the stridulating vein is only connected with the

second axillary vein by the vein c. The two branches of the second axillary vein (2’, x")

remain free and form along the inner margin a sort of corneous shell, the dex (7), on

which the musical sounds are generated. If normal, as in the left elytron, the vein a’

ought to bend round to form the transverse vein z', as indicated by the punctured

line; and the vein x" should form the vein z’ (inner margin of the speculum) as in

fig. 33; but the two branches of the second axillary vein (2’, 2) being broken, and

thrown back against the inner margin to form the dex, are thus separated from their

post-axillary portions (z’ and 2"), so that their homologies are no longer apparent *.

The consequence of this modification is that the second post-axillary vein (z”), beg

separated from its base (2’, a’), fuses with the stridulating vein 4; or, in other words,

the vein A is prolonged backwards to replace the normal vein (z") and to close the

speculum (s).

The Conocephaline principally inhabit Tropical America, very few of them occurring

in the United States. The known genera and species of Central America are not

numerous.

* In fig. 34 the vein z’ is theoretically the continuation of 2’, and z” is the continuation of z'', as in the

left elytron; but x’ being pushed back to the inner margin of the elytron, the vein A is prolonged to replace

it, 80 as to complete the speculum.

This species is the only one known to us which bears two rows of spines on the

inferior edges of the anterior and intermediate femora. We have described it here so

as to prevent a possible confusion with C. capito. |

Obs.—C. capito and C. cephalotes are of robust build, and by their wide and flattened

face they present some analogy with the genus Lirometopum (which, however, is

destitute of a vertical horn); C. cephalotes, moreover, has crenulated carine on both

sides of the face and short elytra.

This insect has a most extraordinary appearance on account of its enormous, flattened

head. ‘The elytra are very closely reticulated, so that the small transparent cells are

punctiform; but seen by reflected light, at least in the marginal field, the cells appear

to be black, the veins forming the wider net of the reticulation looking as if they

were margined with small black spots. This last-mentioned character is not apparent

in discoloured specimens.

Our unique specimen is now in very bad condition, so that we are unable to give a

complete description to supplement the original diagnosis. It may be noticed that the

legs are longer and more slender in this species than in any of the other known members

of the genus; the process of the vertex is also more acute than usual. Fortunately, we

possess a good figure which was made long ago from the type.

This species is very like C. pichinche, Boliv., in colour, but it is much larger, and has

the process of the vertex twice as long as in that insect, and not at all conic, and the

elytra reaching much further beyond the hind femora. It differs from C. guttatus,

Serv., in its longer ovipositor and shorter elytra; and from C. mexicanus in having

the four anterior femora maculated with black. C. aztecus should be placed near

C. maxillosus (Fabr.), from which it may be distinguished by the shorter and broader

process of the vertex, not attenuated at the tip, and by the spotted femora.

elytra are frequently dotted with black, and sometimes have the anterior margin brown.

The pronotum generally has a brown marginal stripe, which is continued on to the

principal vein of the elytra.

396 ORTHOPTERA.

This genus includes a large number of species, spread over the whole world. It is

probable that many of the South-American forms will eventually be found in Central

America.

The tympanum is membranaceous in both elytra in the males, and peculiarly formed ;

its second transverse vein, instead of being parallel to the stridulating vein, is oblique

and divides the speculum into two triangular cells.

Tribus PPEUDOPHYLLIN.E*,

Pseudophyllide, Brunner v. Wattenwyl.

Tarsi depressi, articulis primo et secundo utrinque dilatatis et longitudinaliter sulcatis. Caput rotundatum vel

cinctum, ergo haud prominens, Pronotum sulcis transversis duobus distinctis impressum. Tibie antice

(Brunner v. W.)

The Pseudophylline may be divided into various groups by the structure of the

elytra, three types of which may be here noticed, two of them being American :—

1. In this group the elytra are more or less narrow, generally but little coriaceous,

and somewhat transversely convex—so that in repose they form a rounded sheath

(cover 2) for the body; they are cylindrical above, being compressed at the apex only.

The surface of these organs is either grey and rough, imitating the bark of trees, or

green, imitating leaves. In the males the anal field is small, and the tambourine much

* Principal recent works referred to for this tribe :—

C. Srit, Recensio Orthopterorum, part 2. Stockholm, 1874.

Cu. Brunner von Wartrenwyt, Monographie der Pseudophylliden. Wien, 1895.—A very complete and

genuine monograph of this tribe, which we have followed in this work. .

+ This character distinguishes the Pseudophylline from the Mecopodinee, these latter having the posterior

tibia armed with two apical spines. Redtenbacher, however, has pointed out that a few Australian species,

which have quite the facies of Pseudophylline, seem to make an exception in this respect ; but Brunner v.

Wattenwy]l states that the venulation of the elytra of these aberrant forms is more like that of the Mecopodine,

and he prefers including them in that tribe. The Mecopodine are not represented in the New World.

resembles that of the Conocephaline (comp. anted, p. 374, and Tab. XIX. figg. 33, 34),

but with the axillary veins (2’, x") at the base placed closer together and sometimes not

distinctly separated. There is always a central speculum, of elliptic, ovate, or piriform

shape. The tympanal field of the left elytron is frequently coriaceous, the speculum

itself being opaque. The tympanal field of the right elytron is coriaceous, but bears

always a large vitreous speculum ; it has no second (external) speculum, as visible in

the Conocephaline (Tab. XIX. fig. 34, e).

2. In the Group Pterochroze the elytra are very wide and completely flat, exactly

imitating dead or living leaves; they fold together like two sheets of paper, as in

the majority of the Lepidoptera Rhopalocera (only downwards instead of upwards),

the elytra not enveloping the body, but concealing it between their two flat surfaces.

In the males of the mimetic types (Pterochroza, Mimetica, Typophylium, &c.) the anal

field is very small, and the tambourine bears a small piriform speculum. In the less

mimetic types, of green colour, the tympanal field is larger, and sometimes more or

less coriaceous in both elytra.

3. In this group, as in the first, the elytra in repose form a cylindrical covering for

the body, but they are very differently constructed. In the males the anal field is very

large, wide, and extends nearly to the apex of the elytra, and it is modified in its whole

length, so that the tambourine extends over the entire field; but the tambourine,

however, is not membranaceous, the whole of the anal field being semicoriaceous. The

second ulnar vein anastomoses with the anal vein, generally before the middle of its

length, and at this place the anal field is cut by a transverse fold or sulcus (which

extends also laterally across the ulnar area). ‘The anal field is thus divided into three

parts:—The first part is small, and occupies the base up to the stridulating vein; the

second part, placed between the stridulating vein and the transverse ridge, forms an

elongated square area which ought to contain the vitreous speculum, but this is

completely wanting, and the whole area is reticulated ; the third part, generally much

the longest, occupies the posterior half of the anal field, and it is furnished with

numerous approximate transverse veins, which perpendicularly pectinate the anal

vein. The last-mentioned portion of the anal field, although more or less coriaceous,

is, as well as the second portion, a sonorous field. In some species the male elytra are

swollen, forming an ample covering round the body, and very sonorous, the second

part of the tympanal field being extended very far back. The species of this section.

are confined to the Eastern Hemisphere, and form the groups Pseudophyllites and

Phyllomimites (‘ Sauterelles vertes,’ Pictet and Saussure).

We have omitted the genus Aprion from our enumeration, although one species,

A. (Acanthoprion) aztecus, has been described by us as from Mexico *; we now have no °

doubt that the insect was labelled with a wrong locality.

This genus should be placed between Xeropteryx, Redt., and Tetragonomera, Stal. It

is distinguished from Xeropteryx by the form of its pronotum, the very narrow opaque

elytra, &c. From Tetragonomera it differs in having the pronotum spinose, with its

posterior margin tuberculated in the middle and its anterior margin dentated; the

elytra longer, not much attenuated at the tip, and more membranaceous; the anterior

femora spinose beneath and not margined above ; the intermediate tibize with a double

row of spines above, &c.

The general description is taken from a female specimen from Capetillo. This example

has the pronotum more strongly granulate than in the male. The last-mentioned sex

is easily distinguishable by the emarginate infra-genital plate, this being divided for

half its length. G. deminuta resembles G. fissa, but it is much smaller, and the styli

are not incrassate at the apex as in that species.

Very like G. munda, Brunn., from which it differs in having the spines of the legs

black. It resembles also G. accola and G. nigrospinosa, Brunn., but the wings are not

tessellated with pale lines as in those species; the pronotum is strongly granulated

(while in G. accola it is only rugulose); the ovipositor (instead of being long and

slender) is short and wide at the base, wider than in Lichenochrus variabilis, Brunn.

The elytra are adorned with pale spots, which are arranged in a mosaic pattern, much

as in G, pallidespinosa and G. jissa.

IDIARTHRON, Brunn.

Idiartkron, Brunn. v. W. Monogr. der Pseudophylliden, p. 172.

This genus is chiefly confined to Central America, but extends southwards to the

Amazon valley. All the species are very similar, and they can be separated only by

the structure of the anal pieces. The colour is always fulvous-grey, but it is most

likely somewhat olivaceous in life; the spines of the femora are usually black, but in

one species those of the anterior and intermediate pairs are paler in colour. The form

of the supra-anal plate is often difficult to make out, the anal pieces being partly or

entirely concealed by the cerci.

The true limits of two of the species are not clear to us, on account of the singular

variation in the shape of the anal pieces of the males.

TI. incurvum is a very distinct species, characterized by the curved process of the

supra-anal plate in both sexes and by the simple male cerci.

I. subquadratum seems also distinct by the short, quadrate supra-anal plate in both

sexes, its pale colour and subpubescent surface (rarely rounded, corneous, rufous, and

polished), and by the simple male cerci, these latter being conical at the tip and without

a black apex.

I. furcatum is not so well defined, owing to the male cerci not being always distinctly

furcated. Sometimes their superior branch becomes short or is reduced to a rounded

424 . ORTHOPTERA.

tubercle, and the inferior branch has another tubercle above at the base. In this case

the cerci incline to the trituberculate form characteristic of J. atrispinum. The process

of the supra-anal plate of the male has a foveola at the base; it is variable in length :

when long, it is curved down at the base; in some specimens it is straight and only

slopes downwards, in others it is shorter, forming a transition to that of J. atrispinum.

In the females the supra-anal plate resembles that of the males: it is strongly corneous,

rufous, deeply foveolate at the base, but shorter than in the males, and straightly

attenuated posteriorly, truncate, and bidentate or tridentate, sometimes quite short.

I. atrispinum has the cerci of the males truncate, obtuse, terminated by three

rounded stumps or tubercles, but sometimes the inner tubercle is prolonged and forms

a sort of blunt hook. In this case, compared with the abnormal form frequent in

I. furcatum, it is the superior branch of the fork which appears to be developed, while

in J. furcatum it is the inferior branch, the superior one being here atrophied. The

supra-anal plate of the male, in its typical form, is short and square (Tab. XX. fig. 21),

trispinose, and has a strong foveola at the base; but in some specimens it becomes more

elongate, quite resembling the process of J. furcatum, only somewhat shorter (fig. 17),

making an evident transition to that species. These specimens, therefore, would appear

to belong to J. furcatum, but in the form of the cerci they agree with I. atrispinum.

In the females the supra-anal plate much resembles that of J. furcatum, it being

elongate, corneous, rufous and shining, sulcate, and with a foveola at the base; but it

is more regularly triangular, more widened at the base, much attenuated posteriorly,

narrowly truncate, and rounded or very minutely bi- or trituberculate at the tip.

I. atrispinum and J. furcatum might thus be regarded as one species (?), with the -

supra-anal plate very variable in form in both sexes, and the cerci variable in form in

the male.

In their slender form and long legs this and the following species have somewhat the

facies of Leptotettiz, but their other characters do not accord with those of that genus.

Though we have placed them in the synopsis near C. meroncidioides and C. pollonere,

they are very different in appearance ; moreover, in C. meroncidioides the ovipositor is

nearly as long as the hind femora, and the infra-genital plate ( 2 ) has a round notch,

and in C. pollonere the ovipositor is stout.

This genus is somewhat intermediate between the groups Cocconotites and

Cyrtophyllites. It must be included in the Cocconotites as it has the intermediate coxe

not tuberculated beneath at the base, and the ulnar vein reaching to the tip of the

elytra, but it forms a transition to the Cyrtophyllites by its green colour. In the

coloration of the wings Ewacris is also intermediate between the two groups, the wings

being brown, as in the Cocconotites, but with very differently shaped whitish-hyaline

markings.

Hab. Panama, Volcan de Chiriqui 2000-3000 feet (Champion), Chiriqui (coll.

In its general facies this insect somewhat resembles the genus Dysmorpha, of the

Phaneropterine.

Group PTEROCHROZITES.

Pterochroze, Brunner v. W. Monogr. der Pseudophyll. p. 245.

The species of this group are all extraordinarily mimetic. Their elytra are flat,

folding together perpendicularly in repose, and coloured exactly like the leaves of

trees or bushes. Some are green, imitating living leaves; others have their elytra

tinted with yellow or reddish, like leaves which are beginning to take the autumn tints;

others, again, are brown, like dead leaves. In these latter the mimetic resemblance is

carried still further, the elytra being often marked with brown dots and pale plage,

just like leaves in various stages of decay, so that no two specimens are exactly alike.

Moreover, in these sham dead leaves there are often transparent spots, imitating the

holes made by insects: in the males of some genera (Mimetica and Typophyllum) the

_ margins of the elytra are crenulated and notched, as if gnawed by caterpillars. Some

of these apparent accidents are characteristic of the species, especially the crenulation

of the margins of the elytra and the transparent spots.

The most important of such spots are placed beyond the middle of the discoidal

field, and, although somewhat variable, they constitute specific markings; others are

sometimes spread over the elytra, in quite irregular positions, and must be regarded as

purely mimetic, without fixity, and not specific.

In the green forms the elytra are generally entire, imitating living leaves, neither

altered in their colour nor attacked by insects.

The identification of the species can scarcely be made with certainty without accurate

figures of the elytra.

TANUSIA, Stal.

Tanusia, Stal, Recens. Orthopt. 2, p. 57 (1874) ; Brunner v. W. Monogr. der Pseudophyll. p. 247.

The two species here described differ from the typical Tanusi@ in having the hind

wings less transparent, almost dull ochraceous, and destitute of the apical ocellus; but

it is not advisable to separate them generically.

scutello faciali elevato, superne longiuscule mucronato; verticis rostrum breve, trigonale ascendens,

sulcatum, haud prominulum ; scrobicula antennarum crassissima, anterius late plana, superne angustiora,

elevata. Pronotum antice truncatum, valde compressum, in medio constrictum, sulcis modice impressis.

Prozona canthis elevato-marginatis, tuberculatis. Metazona infundibuliformiter dilatata, retro-producta,

margine postico transverse arcuato, inciso. Lobi laterales postice rotundati, incisura humerali obtus-

angula. Elytra ampla, elongato-elliptica; margine antico basi arcuato, ultra medium subsinuato ;

margine postico recto, apice angulato. Vena discoidalis recta; vena humeralis ante medium ab illa

divergens, ad medium marginem excurrens; vena media ante medium oriens. Campus marginalis venis

obliquis remotis instructus; campus discoidalis in areas magnas divisus. Prosternum spinis brevibus

conicis 2 armatum ; meso- et metasternum utrinque spinam divergentem prebentia. Ale ample, albido-

hyaline, haud ocellate, venis et apice virescentibus. Femora omnia subtus fortiter spinosa; spinis

ultimis lamellaribus, trigonalibus ; lobis genicularibus.inermibus. Tuibie antic valde compress, supra

rotundato-carinate, apice supra leviter dilatate, a latere ad foramina subtus leviter dilatate ; foraminibus

linearibus. Tibize intermedia compresse, a latere basi fusiformes, supra planule, marginibus acutis.

Tibiw postice vix compress, basi a latere leviter dilatate, supra spinulis paucis remotis armate.

Lamina supra-analis lata, convexa, rotundata. Cerci lamellares, trigonales. Lamina infra-genitalis ¢

ovata, apice late subincisa.

This genus is nearly allied to Mimetica, the pronotum being emarginate behind and

similarly formed ; the anterior femora, however, have not all their spines foliaceous,

and the anterior tibie are not flattened above, but compressed... The elytra are

also more elongate, with the anterior field much narrower than the posterior, not

dilated, but, on the contrary, narrowed beyond the middle, and with the humeral

vein separating before the middle in an acute angle; their general shape more

resembles that of the type of Zanusia. The genus should be placed between Tanusia

and Mimetica.

This insect seems to resemble UM. simoni, Boliv., from Venezuela, but it has much

narrower elytra. ‘The short pronotum is characteristic of M. aridifolia, as well as the

strong sulcus which excavates the metazona. This sulcus is not the typical one (which

is obliterated in Mimetica), but a groove formed by the upcurving of the metazona.
