INTRODUCTION.

Tuts volume is devoted to the description and enumeration of five Families belonging

to the Heteropterous portion of the Order Rhynchota, viz. the Pentatomide, Coreide,

Lygeide, Pyrrhocoride, and Capside, as found in Central America.

Aided principally by the collections made so exhaustively by Mr. Champion in

Guatemala and the State of Panama, and by Mr. H. H. Smith in Mexico, supplemented

by the collections of many other naturalists, I have been able ,to study a wealth of

material illustrating a restricted fauna such as is very seldom amassed, and has doubtless

never been surpassed. We possess no complete account of the Rhynchota of any portion

of Tropical South America, and for purposes of comparison are limited to two faunistic

works, which fortunately, however, refer to regions both north and south of our area.

These are the ‘Check-List of the Hemiptera-Heteroptera of North America,’ by Prof.

Uhler, published in 1886, from which I eliminate the Mexican and Antillean species

included by that author, and the ‘ Hemiptera Argentina’ of Prof. Berg, 1879-84. Other

papers exist relating to different regions of South America—notably that of Stal on

the Hemiptera of Rio Janeiro,—but these are of a more or less fragmentary character,

aud the only moderately complete catalogues which can be used for statistical reference

and comparison are those of Berg and Uhler. Additional genera and species have been

more recently described from both the regions studied by those entomologists, but I

have not gone beyond their work and dates.

Penratomipa.—This family of Heteroptera, mostly containing large and handsome

species, readily observed and not difficult of capture, has long been a favourite one

with collectors and much studied by students of the Order. We may therefore, with

some confidence, accept our own enumeration as fairly representative of Central

America, and also rely on the approximate completeness of the lists given by Berg

and Uhler. Our region is at once seen to be very rich in Pentatomide, as I have

enumerated 104 genera and 377 species, as against 07 genera and 149 species given

for America north of Mexico, and 41 genera and 105 species recorded in the Argentine

fauna. When our 104 genera are analysed—for our knowledge of the distribution of

vi INTRODUCTION.

species is too limited to allow comparative deductions to be made thereon—we arrive

at the following conclusions, derived of course, from present information only :—

Of these genera, 26 are also found in the Antillean sub-region; but the records of

the Rhynchotal fauna of these islands are still very imperfect, and our knowledge is.

almost confined to Cuba and Jamaicaf. The following genera have also a wide

distribution outside the American continent :—Canthophorus—Kurope, Japan ; Pangeus

—Australia, New Zealand; Onalips—West Africa ; Geotomus—Europe, Asia, Africa,

Madagascar, Australia; Audinetia—India and the Malay Archipelago; Podisus—

Europe, Asia; Nezara—Europe, Asia, Africa, Australia; Piezosternum—Tropical

Africa.

In his Monograph of the Tertiary Insects of North America, Mr. Scudder has

included the genus Cyrtomenus as representing the remains of a fossil species found in

the Tertiary beds at Green River.

CorEIDaZ.—This family, consisting of large and conspicuous insects seldom absent

from collections, may also be considered as moderately well enumerated in most

faunistic works, and hence we may with considerable certitude compare our list of

Central-American genera and species with those already referred to of the Argentine

Republic and of North America. Central America is thus shown to possess 75 genera

and 210 species, as compared with 84 genera and 59 species recorded by Prof. Uhler

from the Nearctic region, and 36 genera and 60 species enumerated by Prof. Berg as

belonging to the Argentine fauna. |

Analysing the distribution of our 74 genera, the following results are obtained :—

* T here follow the method of Dr. Sclater, as applied to the species of Mammalia, in the Introduction to the

volume devoted to that Class in this Publication.

+ The results of the Antillean expedition of Mr. H. H. Smith are not yet published.

INTRODUCTION. vii

Of these genera, 17 are also recorded as found in the West Indian Islands, whilst

Alydus, Stenocephalus, Neides, and Corizus are also well known in Europe.

Amongst the Tertiary insects of North America, Mr. Scudder has recorded the

presence of the genera Cydamus, Protenor, and Corizus.

Lye¢z1pa#.—Our statistical comparison in this family is only applicable to the Nearctic

fauna, as the genera and species enumerated by Prof. Berg as representing the

Argentine fauna are manifestly inadequate in number, ‘This is not surprising when we

remember that the capture of the members of this family requires, in many cases,

acquired knowledge of their habits. In the Argentine Republic collecting or field

entomologists are few in number, but in North America the case is different, and in

Central America we had the services of Mr. Champion, who had previously collected

Rhynchota in England. |

I have been able to determine 54 genera and 175 species of Lygeidze from Central

America, as against 40 genera and 87 species in Prof. Uhler’s list of the Nearctic

Heteroptera, and 18 genera and 31 species recorded as found in the Argentine Republic.

The distributional analysis of our 54 genera is as follows :—

Nearctic genera, z.e. Central Am. gen. also found north of Mexico. . . 7

Of the above genera, 8 are also recorded from the Antilles, but the large number

at present known as peculiar to our fauna is evidently only in relation to the many

now for the first time described, some of which will be doubtless found to have also a

more southern habitat. The Lygeide are often widely distributed throughout the

world, and 17 of our genera have that ubiquitous character :—

Our genera are also well represented in Mr. Scudder’s list of the Tertiary insects of

Vili INTRODUCTION.

North America, and comprise Lyg@us, Nysius, Geocoris, Ligyrocorts, Cholula, Trapezo-

notus, and Rhyparochromus.

PyrrHocorip#.—This family is merged by some authors with the Lygeide. The

absence of ocelli is the distinguishing character of the family, but in some genera these

only just reach the vanishing-point, and the position of such insects becomes difficult ©

to determine.

I have identified 10 genera and 33 species as found in Central America, contrasting

with 3 genera and 7 species given as found in the Nearctic area, and 2 genera and |

6 species recorded as belonging to the Argentine fauna. Our 10 genera are thus

distributed :—

Nearctic genus, i.e. Central Am. gen. also found north of Mexico . . . a

Genus found in Central America? and nearly throughout the old World . 1

Of these, two have been recorded from the Antilles; Dysdercus is found in Australia

and generally throughout the Ethiopian and Oriental regions, whilst Pyrrhocoris rests

on doubtful or uncorroborated evidence as a Central-American genus. Specimens of

P. apterus were received in the Van Patten collection as from Costa Rica, but no other

examples from any of our localities have been secured, nor has any other record been

made of its presence on the American continent. Moreover, I am informed that a

few accidental inclusions have been found in this collection.

In Tertiary times, according to Mr. Scudder, the genus Dysdercus existed in North

America as at the present time.

Capsip#.—In this family our collections proved very representative, and I have

enumerated 80 genera and 313 species as found in our fauna; contrasting with 80

genera and 156 species in Prof. Uhler’s Nearctic list *, and 26 genera and 58 species

as recorded by Prof. Berg in the Argentine fauna.

An analysis of the known distribution of our genera can only be of a fragmentary

and partial character, as so little is known of the Capside found in the tropical portion

of South America, and future research in the latter country will doubtless greatly alter

the deductions now made.

* Considerable additions both in genera and species have recently been made to the Nearctic Capside ; but,

as before stated, our comparison is confined to the List published in 1886.

I have only been able to find a record of one of these genera as inhabiting the

Antilles ; but this, of course, denotes merely a want in entomological knowledge. A few

of the genera are very widely distributed. Miris, Megacelum, and Lygus are found in

Europe, Africa, and Asia, the first-named being also recorded from Polynesia, and

probably existing in Australia. Calocoris has a wide Palearctic distribution.

In the Tertiary deposits of North America, Mr. Scudder has recognized the remains

of Hadronema, Pecilocapsus, Carmelus, and Fuscus.

The total enumeration of the preceding five families of Central-American Hetero-

ptera is thus seen to amount to 323 genera and 1108 species, the distributive

relationship of which is largely with the fauna south of our area, and one which

will prove to be still larger when that fauna is more worked and described. Our

collections have been particularly exhaustive from Mexico, Guatemala, and the State

of Panama; from Costa Rica our material was smaller, but it yet produced an

exceedingly large percentage of new species, and the writer looks to Costa Rica for

many future additions to the Central-American fauna. ‘The numbers of new genera and

species described are as follows:—Pentatomide, genera 11, species 120; Coreide,

genera 4, species 63; Lygeide, genera 26, species 111; Pyrrhocoride, genera 3,

species 13; Capside, genera 61, species 274—total: genera 109, species 581.

Mimicry is not uncommon among the Heteroptera, and in the present volume there

are given several good instances which a reference to the coloured figures will render

quite palpable. Mimetic resemblances to ants are found in Galeottus formicarius,

Dist., a species of Coreide, and in Pheaxr formicarius and P. balteatus, Dist.,

belonging to the Pyrrhocoride. In the Lygeide we have in Toonglasa forficuloides,

Dist., a remarkable mimic of a species of Forficula. The Capside exhibit this pheno-

menon toa greater extent than any of the preceding families, not only mimicking

outside genera, but also exhibiting specific mimicry amongst themselves. Thus, the

genus Lygdus not only possesses a strong Lygeid appearance, but one species

(L. mimicus, Dist.) bears a remarkable resemblance to the genus Oncopeltus, and I

at first casually considered this Capsid as certainly belonging to it; whilst the genus

Cymus, belonging also to the Lygwide, is mimicked by the Capsid genus Falconia.

BIOL. CENTR.-AMER., Rhynch., May 1893. : b

x INTRODUCTION.

Specific mimicry in the Capside is exhibited between Paracalocoris annulatus and

Lampethusa anatina and between Proba gracilis and Lygus tribulis—all local species

described in this volume. Other, though less pronounced, mimetic affinities may be

seen on examining the figures belonging to other genera and species of this family.

In conclusion, I have to acknowledge my obligations for valuable help afforded

in the preparation of this volume. The late Dr. Stal died before the first part

appeared, but not before he had assisted me with some identifications, and I subse-

quently had an opportunity of examining the types of many of his species through the

considerate courtesy of Dr. Aurivillius, of the Stockholm Museum. My late friend

Dr. Signoret placed his collection unreservedly at my disposal, and I had the privilege

of examining and in many cases figuring the Mexican types which it contained. To

the authorities of the Berlin and Vienna Museums our thanks are also due for

Mexican specimens submitted for identification.

Order RHYNCHOTA. |

Suborder HEMIPTERA-HETEROPTERA.

Fam. PENTATOMIDA.

Subfam. CY DNINE.

Cydnina, Stal, En. Hem. v. p. 17 (1876).

This subfamily, as founded by Stal, includes the genus Thyreocoris—which, under

the name of Corimelena, White, was placed by Dallas in his family: Odontoscelide,

and is still kept apart by Prof. Uhler (who has recently written a Monograph of his

family ‘Cydnide as found in North America) in another family he retains under the

name of “ Corimelenide.”

Of the genera at present described, the majority belong to the Nearctic and Neotro-

pical Regions, of which about two thirds only have as yet been recorded from Central

America. These calculations, however, are exceedingly tentative, although both Stal

and Prof. Uhler appear to have had almost all available specimens in their hands when

pursuing their generic revisions.

LOBOSTOMA.

Lobostoma, Amyot & Audinet-Serville, Hém. p. 87 (1848) ; Dall. List Hem. i. p. 110.

This genus contains two species, one of which is only known from Central America.

It is easily recognized by the great dilatation of the second joint of the rostrum.

Bull. U.S. Geol. & Geog. Surv. iii. p. 367.

All the species of this genus which have been described are, with one exception, from

the Nearctic and Neotropical Regions. The exception is C. insignis, Voll., from the

Malayan Archipelago, which, however, on examination, will probably not prove strictly

congeneric.

The triangular scutellum, the submarginal bristles to the head, the convex body, and

stout and thickly spined tibie are well-marked characteristics of this genus.

Some of these characters are liable to obliteration, as Prof. Uhler writing of one species

says :—“ Many of the specimens which I have inspected show conspicuously the results

of wear upon the bristles of the head and teeth of the fore tibie. In two individuals

these appendages were entirely broken off and the bases worn.”

The Central-American specimens vary ouly in their smaller size from the types in the

British Museum; and I have had the opportunity of examining the specimens in the

collection of Dr. Signoret which were identified by Stal with doubt as the above. The

specimen figured is from Costa Rica.

The specimen figured is from Costa Rica, and was compared and identified for me by

Dr. Signoret. It, however, seems to differ slightly from Spinola’s description, that

author describing the pronotum as being “sans impressions transverses.”

3. Cyrtomenus excavatus, n. sp. (Tab. II. fig. 12.)

- Above pitchy, shining, ovate ; sides, legs, and rostrum clothed with bristles. Head rugose, rounded, emarginate

in front, central lobe not reaching anterior margins of lateral lobes. Eyes reddish; ocelli bright shining

yellow. Antenne with the second joint shorter than the third, fourth petiolar at base; first, second, and

third joints testaceous, fourth and fifth pitchy. Pronotum with a large excavation, deepened posteriorly,

extending from anterior margin, immediately behind the head and between the eyes, backwards to a

distinct transverse punctured impression which crosses the pronotum about midway. The excavated space

is anteriorly punctured and finely wrinkled, and posteriorly smooth and sparingly punctured; it is also

somewhat narrowed and rounded behind, and has a small basal, central, elevated shaped stria. Remainder

of the pronotum somewhat sparingly punctured. Scutellum with a few deep punctures, and very faintly

and transversely wrinkled towards apex. Corium rather finely and thickly punctured ; membrane ochra-

ceous, posterior margin pale yellow. Body beneath concolorous, finely and sparingly punctured. Rostrum

reddish brown. Legs pitchy brown, tarsi somewhat paler. .

scutellum.

ARGENTINE Rep. °.

I have followed Prof. Uhler in placing C. castaneus, A. & S., as a synonym of this

species, though Stal, who is seldom in error, considered it distinct. I doso because Prof.

Uhler has had so many specimens through his hands, and also from the examination of

other specimens kindly lent me by Dr. Signoret. Prof. Uhler, however, seems to have

fallen into confusion as to the habitat of this species. In 1875 he records it as from

Texas‘; in 1877 he writes ® :—“ This species has not yet been brought from Texas or the

region west of the great plains, unless the next species (C. obtwsus) shall prove to be a

form of it. The differences separating them seem ample; but long series from many

localities may yield the intermediate links.” It is at least remarkable if C. mutabilis,

recorded as it is by Prof. Uhler‘ as from South Carolina, Georgia, Florida, Guiana,

and Brazil, should yet be absent in the intervening region of Central America, whilst

he gives Mexico as a habitat for his C. obtusus. Berg also describes it as a very variable

species in South America.

SYLLOBUS.

Syllobus, Signoret, Bull. Soc. Ent. Fr. (in litt.).

Dr. Signoret has forwarded me a copy of his description of this genus (in proof), with

the date December 1879. It is founded for the reception of the Cyrtomenus emarginatus, —

‘dela du médian et-formant deux lobules arrondis réfléchis, les bords d’abord convexes

prés des yeux, puis concaves, sinués 4 l’extrémité; les antennes avec le second article

This seems to be a somewhat rare form, especially out of Mexico. I have not hitherto

seen it in collections from Guatemala, Honduras, Nicaragua, Costa Rica, or Panama.

The specimen figured is in the possession of Dr. Signoret. |

Bull. U.S. Geol. & Geog. Surv. iii. p. 378.

This genus as at present restricted is mostly represented in the Ethiopian and Oriental

Regions. Prof. Uhler records one species from the Nearctic Region. JI retain the fol-

lowing species in the genus, as agreeing with Stal’s diagnosis, though that author enu-

merated no American representatives. ‘“Corporis marginibus pilis vel setis sat numerosis

ciliatis; capite intra marginem anticum spinulis vel setis brevibus rigidis sepissime

instructo.” The scutellum is also triangular and narrowed at tip.

. RHYTIDOPORUS.

Rhytidoporus, Uhler, Bull. U.S. Geol. & Geog. Surv. iii. p. 380 (1877).

This genus is allied to those with the scutellum triangular and narrow atthe tip; the

head is furnished with a very obscure submarginal row of small erect teeth and fine

bristles; the ostiolar canal is short, narrow, and subfusiform. It contains but one

species.

_ I am indebted to Dr. Signoret for a comparison and identification of this species. It

the Mexican specimen figured being but 44 millims. in length.

. STENOCORIS.

Stenocoris, Sign. (in litt.). ’

Dr. Signoret informs me that he has founded the above genus, “basé sur la longueur:

to.the genus Geotomus. |

1. Stenocoris longulus. (Tab. IV. fig. 10.)

Pangeus, Stal, Stett. ent. Zeit. xxiii. p. 95 (1862); Uhler, Bull. U.S. Geol. & Geog. Surv. in.

pp. 867 & 383. .

This genus is confined to the Nearctic and Neotropical Regions, and is well represented

in Central America. ’

Its principal characters are, scutellum triangular and narrowed at the apex, and the

head without, or almost without, submarginal bristles; pronotum with an “impressed

sinuated antero-marginal line.”

1. Pangeus margo. (Tab. II. fig. 15.)

Hab. N. America, Arizona ?,—Mextco 23, Oaxaca (Mus. Berol.); Guatemata, Zapote

(Champion); Nicaraaya, Chontales (Janson).—Cotomaia; N. Brazit, Para (coll. Dist.).

This species has always a more or less distinct, sharp, linear, longitudinal and central

impression on the anterior half of the pronotum, extending backwards from the fore

border, but not reaching the transverse impression. This character, however, is but

faintly defined in some specimens; .and those from Mexico which have passed through

my hands have been castaneous in coloration, and not piceous as is the case with more.

southern forms. The specimen figured is from Guatemala,

This wide-ranging species seems mostly to vary in the depth and distinctness of the

transverse impression on the pronotum. Dallas identified the South-American speci-

mens in the British Museum with doubt as the Cydnus insularis, Hope. Having satis

fied myself that they belonged to the above species, I forwarded a specimen to Oxford

for comparison with the type of insuwlaris, which Prof. Westwood writes me is a much

smaller species, besides differing in many other respects.

Hab. Norta Americas, Eastern and Southern States as far west as middle of Texas

( Uhler).—Mexico, Matamoras (U//er).

This species is included in the fauna on the authority of Prof. Uhler, who writes :—

“One specimen from Matamoras, Mexico, agrees with the form as seen in the Atlantic

region.” ‘The same author remarks :—“ It is of importance to record that this species

varies very much in some of its structural features. In a few specimens, which were

normal in other respects, the margin of the clypeus was scalloped each side of the

middle, and emarginated in front of the tylus. The second and third joints of the

antenne are sometimes equal; at others, either may be longer than the other. The

ostiolar canal and the plate to which it is attached vary in length and width, and are

often ragged on the posterior margin. Two specimens have been examined by me

which had the ostiolar piece of one side normal, and on the opposite side triangular

and jagged. Usually there are but three pits and bristles on the costal margin; but

occasionally there are four, and in one specimen I noticed five.”

Of this species Mr. Townend Glover writes (Ill. Ins. Or. Hem. p. 21) :—“The fos-

sorial legs fit it especially for digging ; and it is commonly found beneath sticks and

stones on the ground in Maryland. (P.R. U.)”

The specimen figured seems to agree well with Prof. Uhler’s description, and is from

Alvarez Mountains, Mexico. It is most closely allied to P. (thus) curvipes, Dall., in

structure, but lacks the transverse row of punctures near the anterior margin of

pronotum.

6. Pangeus impuncticollis (Sign. in litt.), n. sp. (Tab. III. fig. 7.)

Above black, shining. Head broad; central lobe almost reaching anterior margin of head, which is reflexed ;

coarsely wrinkled near lateral borders. Pronotum smooth, shining, impunctate. Scutellum with a

catenulate row of coarse punctures at base, which also extend less regularly and rather more coarsely

along two thirds the length of each lateral margin; a few coarse and scattered punctures on disk. Corium

with a claval catenulate line of coarse punctures, and embolium also coarsely punctured; disk with a few

fine and obscure punctures. Membrane fulvous at base, pitchy towards apex. Body beneath concolorous ;

rostrum and anterior legs dark castaneous. Antenne castaneous; third joint faintly luteous at tip,

remainder wanting.

Long. 93 millim., lat. 53 millim.

Hab. Mexico; Panama (coll. Sign.)

The lateral pronotal borders are sparingly fringed with long hairs. This species is

allied to P. discrepans, Uhler, but differs in the impunctate pronotum and different

punctuation of the corium. |

One specimen received from the Berlin Museum agrees with the typical figure and

description, but varies in the colour being castaneous, thus being concolorous with the

legs. The eyes are also pale luteous:

| ECTINOPUS.

Ectinopus, Dallas, List Hem. i. pp. 110, 121 (1851).

This genus at present contains but one species, which has hitherto been found in

» the Central-American and Amazonian subregions of the Neotropical Region.

It is distinguished by the extreme length of the posterior tibiee, which are half the

8 -HEMIPTERA-HETEROPTERA.

length of the body; they are also more slender, with their spines weaker than in the

genus Cyrtomenus. The corium is also shorter than the membrane.

An examination of Walker’s type in the British Museum has shown that his thus

fusiformis is a small and somewhat dull-coloured specimen of the genus Ectinopus, and

that it cannot be separated from this species.

MICROPORUS.

Microporus, Uhler, Bull. U.S. Geol. & Geog. Surv. ii. p. 275 (1875), iii. pp. 366, 373 (1877).

This genus at present contains but three species—one Nearctic, and the other two

found in the Central-American subregion. The generic characters as enunciated by

Prof. Uhler are :—“ Scutellum broadly rounded ; head with comb-teeth ; body deep and

convex; ostiolar canal short, at tip enlarged into a circular auricle; surface hairy

exteriorly.”

The specimen figured is from Guatemala, and does not appear to differ from the

Mexican or more northern representatives of the species.

2. Microporus mexicanus, n. sp. (Tab. IV. fig. 8.)

Piceous, shining. Head with the anterior portion obscurely channelled and wrinkled. Antenne with the

three basal joints ochreous, the two apical ones luteous; second joint much the shortest; third, fourth,

and fifth subequal. Pronotum: with a somewhat obscure transverse impression, behind which it is

distinctly and somewhat densely punctate; the anterior portion of the pronotum has the lateral borders

broadly and coarsely punctate, the anterior margin narrowly and more obscurely punctate, and the disk

impunctate. Scutellum obscurely wrinkled, somewhat thickly punctate, with the base narrowly impunc-

tate ; apex depressed and angularly rounded. Corium somewhat densely punctate, membrane pale whitish,

Body beneath concolorous. Abdomen with the disk smooth; sides very finely and obscurely punctate.

Fore and intermediate tarsi luteous ; hind tarsi luteous, with the apical joint piceous.

Long. 5 millim., lat. basi pronot. 3 millim. °

Hab. Mexico (Mus. Berol.).

Allied to IZ. obliquus, Uhler, but differs from the description of ‘that species in the

following particulars :—It is much larger; the scutellum is not “polished, remotely

punctate,” as in Uhler’s species, but obscurely wrinkled and thickly punctate. The punc-

tured lateral borders of the pronotum also differ from the description of M. obliquus.

LOBONOTUS.

Lobonotus, Uhler, Bull. U.S. Geol. & Geog. Surv. vol. iii. pp. 8367 & 395 (1877).

As Prof. Uhler remarks, this is the most singular and aberrant of all the forms

of the North-American Cydnine. The elongated and produced head renders this genus

very distinct. One species only is at present known.

1. Lobonotus anthracinus. (Tab. IV. fig. 7.)

third from Mexico is in the Berlin Museum, and is the specimen figured.

According to Prof. Uhler the females usually have a sublunate white spot near the

postero-exterior corner of the corium. Mr. Say appears not to have known the female

of this species; for he makes the absence of the white spot a specific difference, ‘“ Spe-

cimens occur with no spots on the corium, with the spots reduced to mere poinis, or

with a spot only on one wing-cover.” ‘The specimens examined from Mexico are with- .

out the spot on corium. | |

ovate, and the scutellum large, not covering the outer margin of the corium, but in

many cases almost or quite covering the membrane. ‘Tibiz more or less spinous.

Prof. Uhler states that this species was obtained above the “ timber-line” in the

mountains of Colorado by Lieut. W. L. Carpenter, and from that elevation differed in

no important manner from the specimens common to Kansas, Texas, Missouri, and

the Atlantic region. It was found in the month of August near Colorado springs, con-

cealed among the roots of Yuccas and other plants. Prof. Uhler has had the oppor-

tunity of examining a specimen of 7. histeroides, Say, from the collection of Dr. Harris,

determined by Say himself, and pronounces it to be conspecific with 7. nitiduloides.

Stal recorded this species doubtfully as from Mexico; he writes—“ Exemplum femi-

neum a Signoret missum ab exemplo typico masculino vix differt nisi statura majore,

punctura fortiore, in thorace paullo minus densa.” Specimens from British Honduras,

one of which is figured, agree so well with Stal’s description, that I have not hesitated

to identify them as 7. rastratus, the type of which was from Rio Janeiro.

Subfam. SCUTELLERINE.

The Scutellerine of Central America, roughly calculated, are in genera about two

fifths and in species rather higher, in comparison with the number of genera and

species respectively of the whole Nearctic and Neotropical Regions. With few exceptions

these two regions approximate to the Palearctic in the paucity of the number of species

found in them, the smallness of their size, and the obscurity of their colour as compared

with those of the Ethiopian, Oriental, and Australian Regions. If to these last three

we add the Palearctic and compare the number of genera and species with those of

the Nearctic and Neotropical Regions,. the last are found to contain only about two

thirds the number of the former in genera, and less than half in species.

‘The great amount of colour-variation, and even of size, to be observed in the species

of this subfamily has added much to the difficulty of proper specific identification,

and therefore necessarily increased the synonymic nomenclature. But the more

interesting and much more difficult problem is to find the biological explanation of so

many representatives of different genera all varying in one peculiar and uniform direc-

tion. Thus in the genera Homemus, Sphyrocoris, and Symphylus there are species always

TETYRA. 13

tending to a. variation which is lighter in coloration, and has the addition of two large

rounded subapical spots to the scutellum ; H. proteus, S. punctellus, S. elongatus, S. de-

planatus, and S. pecilus all have varieties in which this peculiarity is uniform.

Macraulax, Dall. List Hem. i. p. 36 (1851).

This genus is well represented in Central America. It is found as far north as Texas,

and extends southwards to Colombia, Brazil, and the Argentine Republic. Of the five

known species, only two remain unrecorded from this region, 7. e. T. pinguis, Germ.,

which has only been as yet announced as received from Jamaica, Cayenne, and Brazil,

and 7. pecila, Berg, lately described from the Argentine Republic. Mr. Dallas

founded the genus Macraulax for Pachycoris bipunctatus, H.-S., two specimens of which

he recorded from Australia. The late Prof. Stal, however, described Herrich-

Schaffer’s species as being a Texan and Mexican Hemipteron, specimens of which are

contained in the Stockholm Museum ; and he also considered (probably from an examina-

tion of the same) that the Texan form Macraular tristis, Uhler, was a synonym of the

same species.

The fundamental characters by which Stal has differentiated this genus from the

following are—‘‘ Segmento sexto ventris utriusque sexus apice sensim rotundato-sinuato

vel medio subrecto, marginibus imis lateralibus anticis thoracis haud reflexis.” The

third joint of the rostrum is much longer than the fourth.

the West-Indian Islands, and extends southwards through Brazil and the Argentine

Republic. Of the six species now associated as congeneric, two are here included.

The remaining described forms are P. fabricii, Linn., P. wilsonii, Uhler (Cuba), P. dis-

crepans, Ubler (N. Peru), and P. obdscuratus, H.-S., described as from South America.

Stal distinguishes this from the preceding genus in chief by “segmento sexto ventris

feminarum apice medio late rotundato producto.” The length of the head is greater

than the breadth between the eyes.

PACHYCORIS. . 15

This is one of those extremely variable species which frequently appear in the

Scutellerine, and in its protean aspect even more than rivalling Tectocoris lineola of

the Oriental and Australian regions. J. torridus is found in the Nearctic fauna, and

probably extends throughout the whole length and breadth of the Neotropical Region.

Vollenhoven described and figured as Pecilocoris eneiventris a form which apparently is

only a variety of this species ; and though its habitat is given as “in India Orientali,” he

states that the type was a solitary specimen in the Royal Museum, “ sans indication

spéciale de patrie, mais provenant de |’Archipel Indien.”

The following are the well-marked varietal forms which have been received from

Central America.

BENEATH DARK SHINING GREEN.

Var. a. (Tab. I. fig. 1.)

Above black or obscure purplish. Pronotum marked with eight, scutellum with fourteen rounded spots, varying

in colour from bright sanguineous to luteous. In some specimens the spots are subequal in size ; in others

they are very unequal, which is instanced in the specimen figured, received from Caché, Costa Rica. In

other specimens of this form the discal transverse series of four spots are enlarged and slightly fused.

Var. 0.

Resembles var. a, as figured above, but pronotum with only six spots.

Var. ¢.

Pronotum as in var.a. Scutellum with macular markings on apical half very irregular. The whole fourteen

spots are never present, sometimes only one is absent, generally two or three.

Var. d. (Tab. I. figg. 2 & 3.)

Pronotal spots as in var. a. Scutellum with the apical five spots much enlarged and irregularly fused. In one

specimen which is figured from Mexico the central longitudinal spots on the pronotum are also fused

together. ,

Var. e. (Tab. I. fig. 4.)

Pronotum with five, six, eight, or in one specimen no spots. Scutellum with the number of spots irregular,

but the two marginal ones always very large.

Pachycoris torridus, var. e, Stal, En. Hem. 1. p. 6.

This appears to be the form described by Burm.! as P. klugit.

Var. f. (Tab. I. fig. 5.)

Above dull rufous. Pronotum with two large triangular black markings at base, two small ones on disk near

lateral margins, and with two larger obscure spots of the same colour on anterior margin.

Var. g.

Resembling var. f, but pronotum and scutellum spotless, concolorous.

Var. h. (Tab. I. fig. 6.)

Colour above as in two preceding vars. Pronotum with four irregular transverse black fascie ; two basal, and

two apical and submarginal. Scutellum with two transverse waved fascie near base, two small spots placed

close together on disk, and two rather larger ones placed severally on each lateral margin a little beyond

middle; these spots and fasciz are black.

This var. seems to resemble var. /, Stal, En. Hem. i. p. 6.

16 HEMIPTERA-HETEROPTERA.

BENEATH LUTEOUS WITH GREEN REFLEXIONS.

Var. 7. (Tab. I. fig. 7.)

Pronotum and scutellum greenish, irregularly marked with reddish spots, which are sometimes confluent. Head

reddish, with two central greenish lines.

This is an extreme varietal form, and ‘seems to come close to the var. ¢ of Stal, En.

Hem. i. p. 6 (1870).

This species is distinguished from P. fadricii, Linn., and the following species by the

shape of the head (which has the lateral margins considerably sinuated), and by the

distinct punctuation of the surface of the same.

Hab. Catirornia (Uhler).—Mexico (var. d), Oaxaca (vars. a, ¢, d); Nicaragua,

Chontales (vars. a, 7); Costa Rica (v. Patten) (vars. a, 6, d, e, f, g, h), Caché (Rogers)

(var. a), Irazu (Rogers) (var. e); GuateMALA, San Juan (var. ¢), San Gerdnimo (Cham-

pion) (var. @).—CoLoMBIa (var. c); BRazi (var. a).

2. Pachycoris dissociatus.

Pachycoris dissociatus, Uhler, Proc. Ent. Soc. Philad. i. p. 21°.

Hab. Muxico, Nuevo Leon!; Costa Rica (Coll. Dist.).

A specimen from Costa Rica seems to agree with Prof. Uhler’s description, and would

appear to be only an extreme melanic variety of P. torridus. Our own specimen is

separated from that species by the much more deeply sinuated lateral margins of the

head. I have unfortunately been only able to examine one specimen, the antenne of

which are absent.

This genus is best recognized by the more or less erosion of the abdominal margins, and

the hexagonal pronotum, of which the anterior is longer than the antero-lateral margins.

Two species are recorded, both from the Amazonian subregion, one of which we now

include in this fauna. Z

ORSILOCHUS.

Orsilochus, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 493.

Of the five species at present known as constituting the genus, three are found in

Central America, one, O guttatus, H.-S., is a Nearctic form, and the other, 0. leuco-

pterus, Germ., has only been recorded from Brazil.

ORSILOCHUS. 17

This genus has a considerable resemblance to Pachycoris; the second and third joints

of the antenne, however, are subequal in length, and the head is also more triangular,

robust, and convex, which serve as superficial characters by which to separate the two

genera.

This species is subject to great variation; the forms figured are vars. punctatissimus

and complicatus, the first from Mexico, the second from Costa Rica. The var. margi-

nellus, Dall., differs from punctatissimus in having a central pale longitudinal line, and

a transverse black patch on each side near anterior margin of pronotum. The habitat

of the type was unknown ®; but the probability necessarily is that it is found in the same

region with the other varieties. The type is slightly larger than usual forms of P. punc-

tatissemus; but only one specimen exists in the British Museum, though Walker (Cat.

Het. i. p. 47) records three other specimens of the form from Mexico. An exami-

nation, however, shows that Walker, under the names of P. boscit (where he inserts

punctatissimus as a synonym) and P. marginellus, has fallen into terrible confusion,

and mixed not only P. punctatissimus and P. marginellus in each case together, but also

with them species of other genera. His habitats are therefore useless; and this expla-

nation is necessary for not recording them. The var. complicatus is a larger and more

robust form, the size as stated by Prof. Uhler being length 11 millims., hum. breadth

62 millims.; the apex of the scutellum appears rather more abruptly deflexed; and the

punctuation of the pronotum in some specimens is slightly different. But intermediate

forms between all these varieties exist, and a fine series (all from Mexico) received

from the Berlin Museum afforded an excellent opportunity of certifying the same.

The colour beneath also varies from dark greenish black to slightly mottled luteous.

The specimen figured is in the State Museum at Stockholm; and I am indebted to

Prof. Lindstrém and Dr. Jacob Spangberg for affording me the opportunity of figuring

this and other Central-American species described by the late Prof. Stal. The specimens

received from Guatemala vary principally in the width of the subdiscal transverse fasciz

and the size of the apical spots.

DYSTUS.

- Dystus, Stal, Stett. ent. Zeit. xxiii. p. 82 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 494.

This genus was founded by Stal for the reception of the following species, which it

at present alone contains :—

Tiridates, Stal, Ofv. Vet.-Ak. Forh. 1867, p. 494.

This genus contains two species, both Mexican, which we have hitherto been unable .

to procure, and therefore have not examined the generic characters. It is allied to

Agonosoma, according to Stal, by the following common characters :—‘‘ Segmento ven-

trali sexto ventris retrorsum valde producto, apice rotundato vel nonnihil truncato,

genitalia tegente; articulo secundo rostri articulis tertio et quarto ad unum longitudine

eequali vel paullo longiore.”

Although very dissimilar above in general markings and coloration to 7. mexicanus,

I have had no opportunity of examining the structural characters of the two species,

que nigris a precedente divergens; an specifice distinctus ¢” |

HOMAMUS.

Homemus, Dallas, List Hem. i. p. 36 (1851) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 494.

This is generally a Nearctic genus. Several species have lately been described from

that region; and more doubtless remain to be discovered. Three species have as yet

been recorded from Central America; but one has also been received from Colombia,

and two are common to the southern portion of the Nearctic fauna.

The principal character of this genus is the produced anterior margin of the sternum

concealing the base of the antenne.

Wolff, in describing and figuring the species as above, gave the locality as Africa

(“ Hab. in Africa, Mus. D. D. Panzer”), thus following Fabricius, with whose Tetyra

grammica he confounded his own species. They are, however, not congeneric—Stal,

who had possibly examined the type, placing the 7. grammica, Wolff, in the genus

Homemus, whilst the 7. grammica, Fab., belongs to the genus Odontotarsus. It is

therefore probable that Wolff, in confounding the two species, likewise copied the name

of the habitat from Fabricius. |

Specimens from Central America appear to be much smaller than more northern

forms. Of these Uhler states that in general western mountain specimens are not so

dull-coloured nor so broad as those which occur on the eastern side of the continent ;

and in Maryland the species seems to affect the colder parts of the State, where the

vegetation is from a week to ten days later in developing than in the lowlands of the

warm areas. ,

Above ochreous, somewhat closely punctured with brown and marked with irregular dark brown fascie. Head

with two central lines, and lateral borders for two thirds from base pitchy brown. Pronotum with a

central narrow elongated oval fascia of brown punctures, and two central dark brown fascie, which,

commencing on anterior margin a little to the left and right of the base of central lobe of the head, are

continued almost longitudinally halfway across towards base, when they are suddenly deflexed and ter-

minate near the lateral angles of the scutellum; on either side of these are two oblique fascie of the same

colour running parallel with the lateral borders. Scutellum with the following dark brown markings :—

four central irregular spots at base, the inner two much the smallest; two oblique fascie on each side

extending from base to about centre of outer margin ; two large irregular transverse fascie situated a little

beyond centre, almost meeting on disk, where they are widest, and narrowed to where they terminate near

outer margin; behind these an elongated crescentic fascia near apex. A central pale longitudinal line

extending through head to apex of scutellum.

Underside of body pale ochreous, with the lateral borders broadly covered with dark punctures, which are much

darker and confluent on lateral borders of sternum and head. Disk of abdomen with a few scattered

punctures. Legs setose, thickly and very coarsely punctured with pitchy brown. Rostrum just passing

posterior cox, with the two apical joints pitchy. Antenne with the second and third joints subequal.

SYMPHYLUS.

Symphylus, Dallas, List Hem. i. p. 87 (1851); Stal, Ofv. Vet.-Ak. Férh. 1867, p. 495.

This genus probably extends throughout the Neotropical Region ; it is also common

to the Antillean fauna. It comprises a number of variable forms which cluster round

each of its species. As a rule, in separating the species of this difficult genus, size and

shape are of the greatest value. The variation seems to run from simple punctuation

to the formation of the punctures into curved and oblique fascie.

The small triangular and anteriorly pointed head, together with the shortness and

curvature of the odoriferous orifice, sufficiently distinguish this from the préceding

genus.

In a second specimen the punctures on the pronotum (at base) and scutellum

(on lateral border) show signs of amalgamating into curved lines, as in varieties of

other speeies of the genus. There is also a faint indication of a pale scutellar apical

spot.

4, Symphylus signoreti, n. sp. (Tab. II. fig. 9.)

Ochreous yellow, marked with reddish-brown fasciz. Head closely covered with reddish-brown punctures.

Pronotum thickly punctured and marked with reddish brown, and with a central pale crescentic fascia,

which commences near lateral angles of seutellum and extends to near anterior margin, where it is elon-

gated in a rectangular manner anteriorly, and in a short narrow line posteriorly ; this pale fascia is

bordered on each side with reddish brown. Scutellum with a Maltese-cross-shaped fascia of brown

punctures on disk, on each side of which the lateral borders are broadly reddish brown from base to

medium, enclosing a small pale space on marginal border; behind these the apical third is punctured

and irregularly marked with the same colour, bordered darker inwardly and containing a rounded pale

space at apex. Underside ochreous; lateral borders broadly covered with dark punctures. Legs coarsely

punctured with reddish brown. Rostrum with the tip pitchy. Antenne wanting.

Long. 6 millim.

Hab. Mexico (coll. Dr. Signoret).

Although in an imperfect condition (antenne wanting), I have not hesitated to

describe this species, in order to insert it in the Hemipterous fauna of the region.

It is perhaps most closely allied to S. obtusus, Dall., from which it differs not

only by its markings, but also by its larger size and its more elongated and linear

form. The head is less suddenly deflexed; and the lateral margins of the pronotum

are much straighter.

5. Symphylus gibbosus, n. sp. (Tab. III. fig. 2.)

Above ochreous unicolorous, punctured with brown, more finely and densely so on scutellum, which has at

the base an obscure central semicircular space, the outer margin of which is somewhat paler in colour.

Body beneath and legs paler than above ; tibiee with a few coarse brown punctures ; antenne wanting.

Long. 5 millim., lat. pronot. ang. 4 millim.

Hab. Mexico.

The pronotum and scutellum are gibbous, the anterior half of the first and head are

abruptly deflexed, and the apex of the latter abruptly, truncated. The lateral margins

of the pronotum are somewhat rounded and ampliated, with the lateral angles

subprominent. |

The species was kindly placed in my hands for identification by Dr. Signoret, in

whose collection it remains.

AUGOCORIS.

Augocoris, Burmeister, Handb. ii. 1, p. 896 (1835) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 494.

This genus is common to the Neotropical Region, having been recorded as far south

as Buenos Ayres; it is also present in the Antillean fauna. .

Stal describes the antenne of Augocoris as “ quadriarticulatis.” ‘They are, however,

apparently three-jointed ; and this at once separates the genus from all others of the

Scutellerine.

Subfam. ASOPINA.

This well-marked subfamily is well represented in the Neotropical Region; and if to

this we add the Nearctic, to which very few genera are entirely confined, we have an

area which possesses nearly half the known genera of the whole world; and of this

portion nearly two thirds are also represented in Central America. But it is in the

Neotropical Region that the Asopine reach their maximum in brilliancy of coloration ;

nor are they inferior in size or structure to those of the more eastern regions, thus in

these respects offering a complete contrast to the preceding subfamily Scutellerine, but

affording agreement with that group in the fact of correlation in coloration between

great brilliancy and excessive variation.

This genus is distinguished by the long and broad scutellum, reaching nearly to the

apex of the abdomen, which is armed with a spine at the base. The anterior tibiz are

dilated in all the species here enumerated. The species found in Central America

number only rather more than one fourth of those comprised in the genus, which is

mostly represented in the Colombian and Amazonian Subregions. One species is

common to Central America and the South Nearctic Region.

Of this variable and wide-ranging species Prof. Uhler writes:—‘ Almost all the

varieties, from an almost uniform yellow jimbriatus through the red and blue diana to

the uniform violet violacea, have passed through my hands.” The Central-American

specimens which I have had the opportunity of examining vary from the form pulchella

(ground-colour greenish black or reddish purple) to the var. violaceus. The form

figured, Tab. I. fig. 14, is from Costa Rica, and has the fore femora banded as in some

of the more typical species, one of which, with the fore femora unicolorous, is figured

on the same Plate (fig. 15), from Guatemala. The specimen confounded by Walker

with S. atricapilius, Hope, is a variety which is reddish and unicolorous, with the legs

bluish black. SS. ornatus, Dall., is described as having the “thorax more than twice

as broad as long,” which would render it distinct, and bring it into the first section of

the genus. I have, however, with Mr. Waterhouse, carefully measured the type and

only representative in the British Museum, and find that the pronotum does not exceed

in breadth more than twice the length. I have included the S. personatus, Germ., as

a variety on the authority of Prof. Uhler, who states that the same form occurs in

Pennsylvania. “In Maryland it frequents Aus glabra, and sucks the blood of the

OPLOMUS. 29

larve of a species of Galeruca which feeds on that plant” (Uhler). “It preys upon the

larva of the Colorado potato-beetle (Doryphora decemlineata). Seven or eight indi-

viduals of this species were found in the web nest of a social caterpillar, and also were

seen destroying the larva of Papilo asterius by Mr. Walsh” (Townend Glover, Ill. Ins.

Or. Hem. p. 68, 1876).

Catostyraz, A. & S. Hist. des Hém. p. 82 (1848).

This genus is at once separated from the preceding by the shape of the scutellum,

which is much more angulated and narrowed beyond the middle. The anterior femora

are armed with a spine near apex; the lateral angles of the pronotum are unarmed ;

and the abdomen is provided with a basal spine, which reaches the intermediate coxe.

With the exception of one species recorded from Cuba, this genus is confined to the

Neotropical Region, and is found in the Central-American, Colombian, Amazonian, and

South-Brazilian Subregions. About two thirds of the known species are found in

Central America, and are all exceedingly variable. Whether these species are poly-

goneutic, and whether these variations are seasonal, must be left to the decision of the

local observer; but it is at least singular that all the varieties of each species start

from, or tend to, one unicolorous form.

A. Head emarginate in front, the lateral lobes distinctly longer than the central lobe.

Var. a. Typical.

The abdomen beneath is unicolorous, with the exception of the ventral spine and accompanying basal spot, which

are either luteous or testaceous.

Var. 6.

Differing from var. a by the first, second, and base of the third joints of the antennz, rostrum, and legs being ©

luteous or testaceous (Stal).

Var. ¢.

Greenish black ; pronotum with anterior and lateral borders and narrow central longitudinal fascia, scutellum

This species also greatly varies in size, specimens ranging from 11 to 15 millims. in

length. It appears to be restricted to Mexico.

2. Oplomus distinctus, sp.n. (Tab. IV. fig. 11.)

Dark greenish, shining; two large oblong spots at base of pronotum near posterior angle, and apical border

of corium luteous. Membrane greenish black; coxe, bases of femora, and tip of ventral spine obscurely

ochreous. Head with the central lobes somewhat acutely pointed and produced beyond the central lobe,

coarsely punctate ; pronotum and scutellum sparsely but coarsely punctured; corium thickly and more

finely punctate. A raised central longitudinal line extending through pronotum and scutellum. Antenne

with the second joint very much longer than the third, remainder wanting. Fore tibie only very slightly

dilated.

Long. 17 millim., lat. 9 millim.

Hab. Mexico (coll. Sign.).

Agrees with the previous species in the shape of the head, but differs from all by the

small dilatation of the fore tibie.

angles produced.

HETEROSCELIS.—PERILLUS. 33

Two species only are known—one recorded from North Brazil, and the other from

Mexico. |

Considerable doubt exists as to the right nomenclature of this genus. Latreille

first described Heteroscelis as a genus of Coleoptera (Régn. Anim. 1829, ii. 18), and

again later in the same work as a genus of Hemiptera. Spinola therefore substituted

for the last the name of Phyllocheirus, which Amyot and Serville subsequently rectified

to Phyllochirus. Stal, however (En. Hem. i. p. 31), has resuscitated the name of

Heteroscelis ; and coleopterists have rejected the name on the ground of it having been

previously used in Rhynchota. The only reason for this last course appears to be that

Latreille had previously (Fam. du Régn. Animal, 1825, p. 419) mentioned or proposed

the name Heteroscelis as a genus of Hemiptera, without diagnosis, only enumerating

that name with seven other generic names under the classification of “‘Antennes de

cing articles.” As, however, coleopterists have rejected the name apparently for this

reason, I have followed Stal in using Latreille’s generic name.

Of the seven species which at present constitute this genus, three are found in

Central America, and the other four are peculiar to the Nearctic Region.

In structure Perillus is allied to Oplomus ; but the scutellum is much more narrowed,

and the ventral spine only reaches the posterior coxe.

thus diagnoses:—‘‘Segmento secundo ventris medio spina vel tuberculo antrorsum

prominente armato, vel saltem medio elevato et antrorsum prominulo; marginibus

lateralibus anticis thoracis, saltem ante medium, crenulatis.” All the species of

Cimex, however, are common to the Palearctic, Oriental, and Ethiopian Regions, one

of these only being also found in Mexico ; and this form is so distinct from the others,

and for it alone Ellenberger founded the genus Audinetia, that 1 retain the same here

as of generic value.

The abdomen is unarmed, and the anterior thighs very obsoletely spined near apex.

Stal? considered this species a synonym of the Pentatoma phymatophora, Pal.

Beauv. I am indebted to the kindness of Dr. Signoret for being able to examine

the type of the last-named species, which seems quite distinct and easily recognized

from MM. grandis by the structure and shape of the pronotal spines. These in

M. phymatophora are not produced forwards, and are acutely pointed, being notched

only on the posterior margin, some distance from the tip; the base of the scutellum is

more sparsely punctured ; and the corium is much less confluently punctured. In the

absence of intermediate forms I have therefore considered it distinct. Palissot de

Beauvoir described his species as from St. Domingo. Owing to the apparent confusion

of the two forms, I have abstained from quoting the habitats given by Stal and Berg, and

have for the same reason discarded those of Walker in his Catalogue of Heteroptera.

PODISUS.

Podisus, Herrich-Schaffer, Wanz. Ins. ix. p. 296 (1853) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 497.

In structure this genus differs principally from the preceding genera, which have a

more or less triangular scutellum (save in Coryzorhaphis), by having the anterior femora

unarmed; the anterior tibiz are not dilated ; and the abdomen is armed with a spine at

the base. It comprises a considerable number of species, which are, with one exception,

common to the Nearctic and Neotropical Regions, including the Antillean Subregion.

Stal has founded several subgenera, which are here treated as sections.

A. Anterior lateral margins of the pronotum crenulated. Lateral angles of the

pronotum unarmed. Apateticus, Dall.

The specimen figured is from Costa Rica, and agrees with some specimens from

Guatemala in being much darker in colour than ordinary forms, such as the Venezuelan

type in the British Museum, or from ordinary Mexican specimens. The species varies

greatly in size, specimens having passed through my hands which range in length from

11 millims. to 16 millims. Mr. Dallas’s figure is in outline only; and that of Herrich-

Schaffer appears much exaggerated in the structure of the pronotum.

The figure is from the type in the collection of the Stockholm Museum, and is copied

from a coloured drawing of the same, which was very kindly made for that purpose by

Dr. Jacob Spangberg. A specimen in my own collection differs from Stal’s description

in having the legs, rostrum, and first, second, and base of the third joints of the antennz

luteous. The tarsi and apices of the tibiz are black.

Stal considered the above synonymous with P. (Arma) fuscescens, Dall. It, how-

ever, differs at once from that species by the pronotal spines, which are not emar-

ginate or notched as in P. fuscescens. Stal describes the antenne as “ articulo apicali

apice excepto pallide testaceo-flavescente.” In two specimens, however, from Mexico

and Guatemala, the antenne are fuscous, with the base of the apical joint obscure

luteous.

tured, with a raised central longitudinal line extending from behind base of head to apex of scutellum,

which also has a dark excavated spot at each basal angle. Corium sparingly punctured, more confluently

so on disk. Abdomen above greenish black, connexivum alternately black and orange.

Body beneath luteous, somewhat thickly punctured with brown, with a broad, central, black, longitudinal

PODISUS. 39

The specimen figured is from Mexico, and differs from the type in having the pro-

notal angles more acute. This, however, seems a very variable character, judging from

an examination of North-American specimens in the British Museum. Some have the

angles subacute, as described by Mr. Dallas; one has them as acutely produced as in the

above Mexican form, whilst another, from Lake Huron, partakes of both characters,

having the right spine prominently acute and the left subacute. Prof. Uhler records

having swept this species from bushes in Colorado during the early part of August;

and, according to Mr. Fitch, in New-York State “this is one of our common tree-bugs,

and will be met with in autumn upon a number of different trees and shrubs.” Mr.

Townend Glover quotes Prof. Riley for the fact that it destroys the caterpillars of

Hemileuca mata.

9. Podisus nigriventris, n.sp. (Tab. IV. fig. 14.)

Above ochraceous, shining, thickly punctured with dark brown. Head thickly punctured, central and lateral

lobes about equal in length. Pronotum thickly punctured, the lateral angles very strongly and acutely

produced, and with a central longitudinal raised line, more prominent on anterior half; crenulated lateral

borders luteous, and lateral spines black at apices. Scutellum thickly punctured, somewhat raised and

transversely wrinkled at base, and with a central raised longitudinal line. Corium sparingly punctured,

more finely and confluently so near interior apical border; membrane dark, shining, brassy. Abdomen

above blackish, connexivum alternately luteous and black.

Body beneath concolorous, shining, thickly punctured, abdomen with the ventral spine and a broad central

longitudinal fascia black. Legs luteous, femora spotted with brown, tibie with the apices and tarsi rosy

brown. Rostrum luteous, apical joint rosy brown. Antenne with the second joint much longer than

the third, which is also shorter than the fourth; third and fifth subequal; first and second joints luteous,

rounded callosity near each basal angle, central basal spot, and apical margins; sternum with seven spots,

two on prosternum, two on mesosternum, and three on metasternum, sanguineous; a black elongated

spot on each lateral margin of scutellum a little below the middle, and a small spot of the same colour on

disk of corium about one third from apex. Membrane pale hyaline, with two central fuscous streaks.

Underside of body, legs, and rostrum luteous, the last with the apex black. Antenne ochreous.

Long. 8 millim.

Hab. Mexico (Belimek ; Mus. Vind. Ces.).

Allied to P. acutissimus, Stal, from which it differs in the absence of the luteous

macular callosities to the scutellum, and in the lateral angles of the pronotum being

somewhat notched behind near its base ; the sternal spots and the coloration of the apex

of the scutellum are also different; the body, too, is more elongated and straightened.

EUTHYRHYNCHUS.

the anterior femora unarmed, but differs in the dilatation of the fore tibie and the

absence of a basal abdominal spine. |

The markings are either red or luteous.

This is the form described by Walker under the name of Arma colorata ®.

It is this insect which Mr. Belt (Nat. in Nicaragua, p. 127) refers to as Pentatoma

punicea. He describes his surprise at on two occasions finding this bug sucking the

juices from dead specimens of a “bright green rosechafer.” Mr. Belt remarks :—

“The bug has weak limbs; and the beetle is more than twice its size and weight, and is

very active, quickly taking wing; so that the only way in which it could have been

overcome that I can think of, is by the bug creeping up, and quietly introducing the

point of its sharp proboscis between the rings of its body when the beetle was sleeping,

and injecting some stupifying poison. In both instances that I witnessed, the bug was

on a leaf of a shrub, with the bulky beetle hanging over, suspended on its proboscis.”

TYNACANTHA.

Tynacantha, Dall. List Hem. i. pp. 77 & 106 (1851) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 497.

Three species of this genus are enumerated, all belonging to the Neotropical Region,

one at present only having been received from Central America. The anterior femora

The name Oxynotus having been used in ornithology by Swainson in 1831, and by a

less followed writer, Rafinesque, in Pisces in 1810, it is clearly right to follow Adam

White, and use the name he substituted. This genus is of somewhat aberrant form

from all the allied genera; the more or less hexagonal thorax and the scutellum, which

does not cover the margins of the wings and is spinous on its disk, are well-marked

characters by which it may be identified. The tarsi are two-jointed.

to both the Neotropical Region and Europe. Six of these genera are represented in

Central America.

Storthia, Perty, Del. p. 215 (1834); H.-S. Wanz. Ins. vii. p. 41 (1844). —

This genus is well marked and peculiar from the others here enumerated by the

head, which is lobate or deeply divided at the apex, and is provided with a spine on each

side in front of the eyes; the lateral margins of the pronotum are ampliated. Nine

species are enumerated, all common to the Neotropical Region, but none of which have

hitherto been recorded from Central America. One of these is now included.

Hab. Panama (coll. Dist.).—Co.omB1a, Bogota!.

I have felt no hesitation in identifying this insect from Stal’s description, not having

seen the type. The eroded condition of the lateral margin of the pronotum allies it to

D. punctata and D. livida, as Stal has clearly pointed out, from which it seems well

separated by the structure of the lateral lobes of the head.

(1872). ,

Platycarenus, Fieb. Eur. H. pp. 77, 826 (1861).

This genus may be differentiated from the preceding one by the following cha-

racters :—the ampliated head, which at the base is as broad or broader than the base

of the scutellum ; and the length of the first joint of the rostrum, which, inserted

towards the base of the head, about reaches the anterior coxe. ‘The species are all

Neotropical; one is also found in Europe; and four are common to Central America.

Stil enumerates altogether fifteen species; and this is probably about the extent of the

genus. Walker (Cat. Het.) has described ten other species; but the only Central-

American one proves to be of synonymic value; and it is possible that the others will

have to be estimated in the same manner.

absence of the strongly marked transverse impression to the pronotum, and in not having

the anterior marginal angle of the pronotum rounded as in that species.

This species is very closely allied to the preceding; but, from an examination of

a typical specimen forwarded to me from the Stockholm Museum with one of

D. clypeata, kindly lent me by Dr. Signoret, I find the differences are well pointed

out by Stal; the principal and guiding one, however, is the impunctate margin of the

pronotum and the base of the corium.

46 HEMIPTERA-HETEROPTERA.

This genus has the abdomen provided beneath with a distinct longitudinal furrow ;

the basal joint of the antenn does not reach the apex of the head; and the lateral

margins of the pronotum are smooth, not denticulated.

Dinocoris is peculiar to the Neotropical fauna; three species are found in Central

America.

A. Second joint of the antenne shorter than the first.

This species is closely allied to D. sepulcralis, Fab., var., as figured by Stoll, Pun.

fig. 94. Stal has described the antennz of both species (Hem. Fab. i. pp. 18 et 19), by

which I differentiate it. The first joint in this species is longer than the second, but

not “fere duplo longiore” as in D. sepulcralis; the third joint is rather more than three

times as long as the second, but not ‘‘ plus quadruplo, fere quintuplo longiore” as in the

other Fabrician species. In the specimen examined from the Berlin Museum, the first

and second joints appear almost equal in length.

I consider the Dinidor punctiger, Hope, as a varietal form of this species, on the

authority of Prof. Westwood, to whom I forwarded a specimen of the form here figured,

and who writes me “seems to be a variety of my punctiger, not having the very decided

linear arrangement of the spots on the corium.” This appearance, however, is shown

in one of the specimens identified by Dallas, but is absent in the second.

B. First and second joints of the antenne subequal in length.

All the specimens examined, including the two identified by Dallas in the British

The base of the fourth and the base and apex of the fifth joint of the antenne are

luteous, the first and second joints subequal in length, the disk of the abdomen beneath

castaneous, and the legs pitchy or castaneous. Palisot de Beauvoir describes the colour

as “‘ presque uniforme.” The specimen figured is from Guatemala.

Stal, En. Hem. ii. p. 10 (1872).

This genus was founded by Dr. Mayr for the reception of a Brazilian species, which

he named FE. nigro-punctatus. I have here added another species to the genus, which

has been received from Panama. The basal joint of the antenne does not reach the

apex of the head; the second joint is a little shorter than the third ; the lateral lobes of

the head are reflexed, longer than the central and cleft at apex ; there is a strong spine

in front of the eyes (Dr. Mayr describes this character, founded on the other species, as

“denticulo obtuso ante oculos subpetiolatus), the anterior angles of the pronotum are

produced into transverse spines, and the posterior angles prominent and rounded.

1. Kurystethus signoreti, n. sp. (Tab. VI. fig. 13.)

Ochraceous, thickly punctured with brown. Head finely punctate, the lateral margins narrowly impunctate,

with a central longitudinal impunctate line which does not reach apex. Pronotum rugosely punctate, a

pale, raised, levigate, transverse line between humeral angles, from which to anterior margin is a pale,

impunctate, obscure, submarginal line, and one of like character enclosing a large central lenticular space ;

lateral margins impunctate ; posterior lateral angles rounded, notched behind. Scutellum thickly punctate,

with a raised convex longitudinal ridge, very broad at the base, and narrowed towards apex. Corium

thickly punctate, membrane pale ochraceous. Underside of body ochraceous, thickly punctured with

brown; stigmata pitchy; legs luteous, spotted with brown. Antenne ochraceous; rostrum luteous, just

passing posterior coxe.

Long. 8 millim.

Hab. Panama (coll. Signoret).

Differs from E. nigro-punctatus, the other species of the genus, by the strong spines

48 HEMIPTERA-HETEROPTERA.

in front of the eyes, the different shape of the posterior lateral angles of the pronotum,

and the length of the scutellum, which slightly passes the apex of the corium. 4.

signoreti differs in some slight respects from the generic diagnosis of Dr. Mayr, as in

the length of the rostrum; but as that diagnosis was based on one species only, I have

felt no hesitation in including this species in the genus. |

PELIDNOCORIS.

Pelidnocoris, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 501; En. Hem. ii. p. 10 (1872).

This genus now comprises but one species, and is thus, according to our present

knowledge, restricted to Mexico. The basal joint of the antenne does not reach the

apex of the head, thus agreeing with the previous genus; the pronotum, however, as

described by Stal, has “angulis lateralibus productis, marginibus lateralibus anticis

foliaceis, lobatis.” The head also is described as ‘‘ad oculos spina longa vel lobo

spiniformi armato, jugis tylo longioribus, ante hunc contiguis.” I have not been able

to examine a specimen of this genus; but the above characters, abstracted from Stal’s

full generic diagnosis, are, apparently at least, characteristic.

once separate Hmpicoris from Dinocoris.

About eight species are known, all confined to the Neotropical Region, one only

having been as yet recorded from Central America. _

Subfam. PENTATOMINA.

Pentatomina, Stal, En. Hem. ii. p. 12 (1872); v. p. 28 (1876).

This subfamily is universally distributed, but reaches its maximum in number, size,

and coloration in the tropical parts of the Old World. Central America in this group is

moderately rich, and contains both identical and representative species of the Nearctic

fauna, which in this subfamily has a strongly marked Palearctic facies, and also possesses

most of the striking and more beautiful forms of the Neotropical Region: ‘Taking the

Nearctic and Neotropical faunas together, and comparing them with those of the

Ethiopian, Oriental, Australian, and extra-European portion of the Palearctic Regions,

we find that the American Pentatomine compare in a proportion of about one third

the number of genera, and rather more than three fourths of the total enumeration of

species.

MACROPYGIUM.

Oxyrhinus, A. & S. Hist. des Hém. p. 113 (1843).

This genus contains two species, both peculiar to the Neotropical Region, and both

found in Central America. The head is armed with a spine near the eyes, and the

lateral margins from these to the apex sinuated, the lateral lobes of the head longer

than the central ; the second joint of the antenne shorter than or subequal in length

to the first.

Prof. Stal gives the relative lengths of the lobes of the head as a sectional character

for dividing the species of this genus. This seems, however, an untrustworthy character;

for with this species two specimens in my own collection vary in this respect, and

sy, HEMIPTERA-HETEROPTERA,

in a third, from the collection of Dr. Signoret, the lobes are subequal in length. It can,

however, be easily separated from B, cariosa, Stal, which is described as having “‘jugis

than the third.

COSMOPEPLA.

Cosmopepla, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 525.

In this genus the lobes of the head are of equal length, the scutellum broad and

rounded at the apex, the lateral angles of the pronotum are rounded or subprominent,

and the nervures of the membrane are longitudinal and simple. The species are found

both in the Nearctic and Neotropical Regions; four only are at present recorded, of

which two are here included.

Its affinity is with the genus Stodiia, found in the Palearctic, Oriental, and Australian

Regions.

Prof. Uhler thinks it probable that this species, the following (C. conspicillaris), and

C. carnifex constitute in reality but one species. He considers the last as “ the con-

tinental form, but which does not cross the meridian of the Sierra Nevada Mountains;

the second does not cross beyond the eastern base of the Rocky Mountains,” whilst C. de-

corata ‘is the subtropical southern form.” All the specimens, however, which I have

seen, or which we have received from Central America, have been constant in character ;

and this view was taken by Prof. Stal, who described a fourth species from Colombia.

Specimens measure from 4 to 74 millims. in length by 3 to 5 millims. in width. The

orange band across the pronotum sometimes invades almost two thirds of its surface ._

posteriorly, and the black colour is replaced by pale dirty rufous.”

MORMIDEA.

Mormidea, Amyot et Serville, Hist. des Hém. p. 184 (1843); Stal, Ofv. Vet.-Ak. Forh. 1867,

p. 527,

This genus is differentiated at once from the preceding by the shape of the scutellum,

which is more or less triangular; it agrees with it, as St&l has accurately diagnosed, in the

character “ tibiis omnibus teretibus, sulco destitutis ;” and is separated from the following

genus Hbalus by “articulo primo rostri bucculas paullo superante.” It is confined to

North and Tropical America ; and in the Old World its nearest congener is the Ethiopian

genus Aspavia. It exhibits a strikingly variable character in the structure of the pro-

notum, the lateral angles of which are generally found in the same species either pro-

duced and spinous or obtusely rounded.

of the antenne, which in typical specimens of M. notulata is black, whilst in the form

described as VW. discoidea, Dallas, it is luteous or testaceous. This last character, taken

in conjunction with the less produced and rounded pronotal angles, induced Stal to con-

sider the two forms as distinct species; but from an examination of a very large series

of specimens I have found this to be also only a varietal character—forms with acutely

produced pronotal angles, as in the specimen here figured, having in some cases the

second joint luteous, whilst in those agreeing with the form described by Dallas the

second joint is frequently black.

CEBALUS.

(Ebalus, Stl, Stett. ent. Zeit. xxiii. p. 102 (1862) ; Ofv. Vet.-Ak. Forh. 1867, p. 527.

This genus is principally separable from the preceding by the length of the first joint

of the rostrum, which is much shorter than in Mormidea, and does not reach the base

of the head. It is not essentially tropical in its habitat, being found in the Nearctic as

well as in the Neotropical Region. Its closest ally in the Old World would appear to

be the Ethiopian genus Durmia.

Prof. Uhler states that this species “ occurs at considerable altitudes on the Black

Mountains of North Carolina, and is not unfrequent upon grassy and shrubby spots in

Georgia and Florida.” “It appears to lay eggs in late spring and towards the latter end

of summer.” ‘The Cuban form is usually larger, and has the lateral angles longer and

more slender than in those from the United States.”

distincte sulcatis, corii margine exteriore basi haud calloso; ab Huchisto et affinibus

Only two species of Galedanta are at present recorded, both belonging to the Neo-

tropical Region. It has considerable affinity with the following genus, Kuschistus; but

the lateral lobes of the head are longer than the central, and the scutellum possesses

a tuberculous callosity in each basal angle.

About forty species are at present enumerated as belonging to this genus. Its range

is the Nearctic and Neotropical Regions ; and it exists under very different climatic con-

ditions. The apex of the head is rounded or emarginate, the central lobe sometimes a

little longer or a little shorter than the lateral lobes ; the tibie are sulcated ; the lateral

angles of the pronotum are prominent, sometimes acute and spinous, and sometimes

rounded as seen in some variable species ; the anterior lateral pronotal margins are gene-

rally denticulated or crenulated: and this peculiarity was originally one of its distinctive

characters ; but recently Stal described a species which has the lateral margins of the

pronotum smooth, thus reducing the value of this portion of the diagnosis, and making

it of sectional value only.

The late Prof. Stal first grouped these divergent forms together as constituting one.

species. ‘This view was afterwards accepted by Prof. Uhler, who studied the varieties

on the spot, and who remarks :—“ No species thus far discovered in this country (North

America) exhibits such a wide range of differences in the form of the pronotum. The

form most common in Maryland has acute and acuminate lateral angles, but longer than

in others from Pennsylvania, Virginia, Louisiana, and some other parts of the South.

EUSCHISTUS. | 59

The large specimens with bluntly rounded angles have not yet been collected by me in

company with the other form.” These, agreeing with the E. lwridus, Dall. (the form

we have figured, with a black-coloured variety), have hitherto been received only from

Guatemala; but the Berlin Museum contains both forms from Mexico. Prof. Uhler

also states that in North America “it sometimes occurs in large numbers in late summer

on bushes in damp situations.” “A whitish bloom often covers the mature specimens

in this region.” ‘This is also observable in the individuals of this species received from

Guatemala.

however, which appears to be variable, and will not bear the value which has hitherto

HYMENARCYS.

Hymenarcys, Amyot & Serville, Hist. des Hém. p. 124 (1843); Stal, Ofv. Vet.-Ak. Férh. 1867,

p- 526.

This must be considered a Nearctic genus. Three species are known, two of

which are widely distributed in North America, while the third, as yet, has only been

received from Mexico. . .

‘The pronotum is unarmed; the scutellum moderately broad at the apex, and not

reaching apex of the corium ; the nervures of the membrane are irregularly reticulated ;

and the rostrum about reaches the intermediate coxe.

Stal has divided this genus into three subgenera; it is, however, preferred here to

use them only as sections. About six species are described, which are purely Nearctic

forms, with the exception of two, one of which is known at present from Mexico only.

64 HEMIPTERA-HETEROPTERA.

The scutellum is somewhat long, triangular, and narrowed at the apex; pronotum

deflexed anteriorly, membrane with longitudinal nervures. These are merely superficial

characters, given here to separate it from the preceding and following genera, some

closely-allied ones not being found in the Central-American fauna.

TRICHOPEPLA.

Trichopepla, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 528.

Two species are described, both Nearctic forms; one is here included in this

fauna.

The rostrum extends to the posterior coxe; the antenne are short, the first joint

not reaching the apex of the head. Pronotum convex, deflexed anteriorly ; lateral

margins slightly reflexed. The body is pilose; and, as Uhler truly remarks (Proc. Bost.

Soc. Nat. Hist. vol. xix. p. 374), “it is the nearest North-American representative of

the African genus Agonoscelis.”

Dryocoris, Mulsant et Rey, Pun. France, pp. 237, 267 (1866).

This genus is common to both the Palearctic and Nearctic regions, one species being

recorded from Mexico.

It is easily separated from the preceding genus by the absence of pilosity, and the

broader head (which is rounded in front), &c. The other characters, more special and

minute, cannot be detailed comparatively here, except by a conspectus of the whole of the

allied genera, which is undesirable in this portion of the work.

Prof. Uhler found this insect rather common, in the nymph stage, upon several kinds

of flowering plants in August. He describes it as varying ‘in the amount of black

upon the two last joints of the antenne, in the presence, or not, of black upon the

acetabular caps, and in the blackish reticulation upon the corium.”

THYANTA.

Thyanta, Stal, Rio Hem. ii. p. 58 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 529.

This genus is confined to the Nearctic and Neotropical regions. It is represented in

the Antilles, and is found as far north as New York, and as far south as Chili and

Buenos Ayres. By Stal it is chiefly distinguished from the preceding genus by the

relative length of the lobes of the head, “jugis et tylo eque longis vel hoc illis paullo

longiore.”

Prof. Uhler states that in Western Hayti this species occurs abundantly in the

neglected and weedy parts of gardens, and that he also obtained a few specimens in that

country from the Palma Christi, or castor-oil plant. He also remarks that “the most

typical form of this species inhabits the West Indies and Mexico; those with the

humeral angles shortest are found in Nebraska.” All the Central-American specimens

which I have examined have the humeral angles well developed and the red thoracic

fascia prominent.

Thelma, Amyot et Serville, Hist. des Hém. p. 107 (1848).

In this genus the lateral lobes of the head are longer than the central, the lateral

margins of the pronotum are denticulated or crenulated, and the lateral angles distinctiy

and acutely produced, the body is always more or less flattened or depressed, and the

abdomen beneath is longitudinally and centrally sulcated. This last character, however,

is a somewhat uncertain one ; for since Dallas on this structural character placed the

genus in his family Halydide, and Stal, who correctly placed it immediately preceding the

genus Lowa, yet still relied upon the sulcated abdomen as a strong differential character

in his ‘ Conspectus Generum,’ species have been discovered in which this ventral furrow

is very obscure and confined to the base of the abdomen only, thus approaching closely

the following genus. The apexes of the femora are unarmed. Chlorocoris is a truly

Neotropical genus; and it apparently has its headquarters in Central America.

A. Head long, triangular ; lateral lobes much produced and subacute.

Dr. Signoret having kindly lent me a type specimen of his C. distinctus, I find it

identical with C. rufispinus, Dall. Both descriptions were published in 1851. Dr.

Signoret’s description was communicated to the French Entomological Society at the

“séance du 8 Janvier,” but was not published until some time afterwards; and therefore,

though Dallas’s work bears date July 1851, it probably appeared first; and I think

that, under the circumstances, the name rujispinus should stand, as it is now generally

recognized and no law is broken by retaining it.

Stal (En. Hem. ut supra) places this species under a section of the genus which he

describes as “ antennis minus gracilibus, pictura nigra destitutis.” This, however, is

incorrect ; in all the species we have examined the colour of the antenne conforms to

that of the two preceding species.

The specimen figured is from Guatemala.

The colour of the antenne in this species varies; concolorous in some specimens, in

others the apexes of the second, third, fourth, and fifth joints are black, as in other

species of the genus. ‘This antennal coloration appears to be of generic character, and

its absence more or less of an aberrance.

The specimen figured is a typical one from Mexico, and was kindly lent to me by

the authorities of the Stockholm Museum. :

CHLOROCORIS. | 69

6. Chlorocoris aberrans, n. sp. (Tab. V. fig. 24.)

Oblong, pale green, thickly punctate and obscurely rugulose. Head transversely striated, lateral lobes a little

longer than central, rounded at apexes and slightly cleft; lateral margins narrowly black. Antenne

ochreous, second and third joints subequal in length, remainder wanting. Pronotum with the lateral

angles produced moderately upwards and forwards, the apexes and hind margins of the spines black;

lateral crenulated margins ochreous. Membrane pale vitreous ; connexivum with the segmental incisures

black. Underside of body slightly paler in hue; legs luteous ; rostrum pale luteous, with the tip pitchy

and just passing hind coxe. Abdomen distinctly and sharply sulcated at base.

Long. 20 millim. ; lat. pronot. ang. 11 millim.

Hab. Costa Rica, Irazu (Rogers).

The elongated body and short blunt pronotal angles readily differentiate this species

from others of the genus. It is most closely allied to C. subrugosus, but is distinguished

by the different shape of the scutellum.

7. Chlorocoris championi, n. sp. (Loxra championi, Tab. VI. fig. 23.)

Green, thickly and coarsely punctured. Head with the lateral lohes longer than the central, rounded at the

apexes and moderately cleft. Antenne pale green, with the apical third of the second and third and the

apical half of the fourth and fifth joints black; second joint much shorter than third ; third, fourth,

and fifth joints subequal. Rostrum luteous, with the apex narrowly black and just passing the inter-

mediate coxa. Pronotum with the lateral angles strongly produced, the spines somewhat directed

upwards and pitchy towards apex; lateral crenulated margins dark orange. Scutellum with a small

basal central orange spot. Corium with the basal margin dark orange; membrane vitreous, with some

obscure pitchy suffusions. Connexivum with the outer margin narrowly dark orange. Body beneath

paler, deeply but sparingly punctate.

Long. 17 millim. ; lat. pronot. ang. 10 millim.

Hab. GuateMa.a, Sabo and Pancina, Vera Paz ( Champion).

The abdomen beneath is only obscurely sulcated towards the base. It is at once

separated from the preceding species by the very different shape of the pronotum and

the proportionally greater width and lesser length of the same. One specimen, received

from Pancina, is-:much paler and more mottled than examples received from Sabo.

8. Chlorocoris irroratus, n. sp. (Tab. VII. fig. 16.)

Pale green, rugulose, mottled and irrorated with luteous. Head somewhat elongate and depressed, the lateral

lobes a little longer than the central, and slightly cleft at apex. Antenne dull greenish, third joint

longest, fourth and fifth a little thickened and subequal in length. Pronotum with the lateral angles

acutely and sharply produced, luteous, and finely punctured with black; lateral crenulated margins and a

somewhat faint central longitudinal line pale orange. Posterior lateral margins of scutellum obscurely

luteous. Connexivum luteous, with a small black spot on each segmental incisure. Membrane pale

vitreous. Body beneath somewhat paler ; rostrum pale green, about reaching posterior coxe. Abdomen

faintly and obscurely sulcated at base.

Long. 16 millim.; lat. pronot. ang. 10 millim.

Hab. Mexico (Bilimek; Mus. Vind. Ces., Mus. Berol.).

This species is very distinct, its more convex body and rugulose and irrorated surface

being in strong contrast with the common facies of the genus. A second specimen

This genus is closely allied to the last, and is really separated by the apexes of the

femora being armed above with a distinct spine; the body is also more convex and less

flattened than in Chlorocoris. Numerous other minor details have been given; but it is

questionable how far these may prove to be constant. Lowa is confined to Tropical

America ; but only about one third of the total species enumerated have as yet been

received from Central America. The Amazonian and Colombian subregions appear to

be the home of this genus. It is also found in the Antillean subregion.

3. Loxa variegata, n. sp. (Tab. V. fig. 25.)

Green, coarsely punctate. Head with the lateral lobes much longer than the central, prominent and acute,

lateral lobes longitudinally ridged and furrowed, lateral margins ochreous. Pronotum with the disk

rugulose, the lateral angles produced into short acute spines, slightly directed forwards ; these spines are

ochreous, with the margins black; lateral crenulated margin ochreous. Scutellum very faintly and

transversely rugulose, with the apex ochreous. Corium obscurely mottled with purplish, a white spot on

disk, and the apical angle ochreous. Membrane pale transparent, some of the nervures pitchy at base.

Antenne ochreous, third, fourth, and fifth joints longest and subequal. Rostrum ochreous, just passing

posterior coxee. Underside of body and legs green; coxe, bases of femora, and disk of abdomen ochreous.

Long. 15 millim. ; lat. pronot. ang. 73 millim.

Hab. Costa Rica, Irazu, Caché (Rogers).

In a second specimen the luteous markings are almost obsolete and the colour

uniformly green.

Allied to ZL. curvidens, Mayr, but differs in having the pronotal angles less acute

and much less produced anteriorly. The posterior margins of pronotum are straight,

not sinuated as in L. curvidens.

MURGANTIA.

Murgantia, Stal, Stett. ent. Zeit. xxiii. p. 105 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 529.

This genus is closely allied to the following (Arocera, Spin.), but differs in the less-

produced odoriferous orifice; the central lobe of the head is slightly longer than the

lateral lobes ; the tibie are strongly sulcated.

Murgantia is a genus confined to Tropical America; only one species ranges into the

Nearctic fauna ; and this, as far as is now known, does not extend further south than

Central America. All the remainder are found in the Colombian, Amazonian, and

Brazilian subregions, one of which is also found in this fauna.

Dr. Lincecum, as quoted by Glover, gives the following account of the life-history of

this insect :—‘“ The eggs, generally ten to twelve in number, are deposited mostly on

the underside of the leaves about the 15th March or beginning of April. These are

set in two rows, on end, cemented together on the leaf, and require about six days in

April or only four days in July to hatch out. There are two broods annually—the first

brood hatching out in April, and the second in July. The young larva resembles the

perfect insect, with the exception of being wingless. Twelve, sixteen, or eighteen days

elapse from the deposition of the egg to the development of the perfect insect, which

passes the winter or hibernates in the perfect or imago state, issuing forth from its

winter retreat at the approach of warm weather. These insects do very great injury

to the plants above mentioned *, especially to cabbages, the leaves they have punctured

immediately wilting (?), as if from the effects of poison. They are said to be exceedingly

numerous and destructive in Texas (and other Southern States), as many as 47,000

having been (in one instance) gathered by hand” (Am. Ent. & Bot.).

Prof. Uhler states that “in the Atlantic region this species seems to be steadily but

slowly advancing northwards. Its introduction into Maryland has been effected since

the late war; and now it is known as far north as the vicinity of the Pennsylvania

boundary line in Delaware.” The same author also remarks :—“ Several of the links

in the chain of varieties between this species and If. munda have already been found;

and we may expect hereafter to see the two species united as mere forms of one.”

We ourselves, however, have seen nothing as yet to warrant such a probability.

The specimen figured is from Guatemala, and, excepting slight variations, is the

dominant form in Central America. Hahn’s figure would seem to represent a melanic

and (judging from my own experience) scarce form of this species.

4, Arocera protea, n.sp. (Tab. VIL fig. 18.) |

Testaceous ; head with the central lobe much shorter than the lateral, the lateral margins raised and reflexed,

the apices of the lateral lobes narrowly but deeply concave, posterior portion from anterior margin of

eyes black; eyes also black. Antenne black, joints gradually increasing in length, last three joints

pilose, third joint clavate, fourth and fifth regularly thickened. Pronotum levigate, with the anterior

border, apical portion of the lateral borders, a round spot at each humeral angle, and two subconical

spots (narrowly connected at base) on posterior margin black. Scutellum with two basal subquadrate

spots (connected with those on pronotum) and apical portion black. Corium with a central transverse

black fascia. Connexivum with the apical margin of each segment black. Underside of body and head

testaceous ; legs, anterior margin of prosternum, some irregularly defined spots on each lateral margin of

sternum, abdomen with a central longitudinal row of transverse fascie gradually diminishing in width

from base to apex, a stigmatal row of rounded spots, and a marginal row of obconical spots black.

Rostrum reaching posterior coxe; first joint testaceous, remainder black.

Hab. Guatemata, San Gerénimo (Champion).

Allied to A. apta, Walk., differing in the shape of the body and scutellum, the central

lobe of the head being shorter than the lateral, and in the colour of the legs, &c.; from

A, crucigera, Hagl., it is distinguished by the shorter rostrum and the colour of the

antenne ; it is also allied to A. rufifrons, Dall., but is separated from that species by

the smaller and more convex body, smaller head, the basal joint of antenne being

concolorous, and the lateral margin of pronotum less reflexed.

5, Arocera affinis, n. sp. (Arocera protea, var. Tab. VII. fig. 19.)

Closely allied to the preceding, but head wholly black, and central and lateral lobes subequal im length; trans-

verse band of corium broken, sinuated and abbreviated posteriorly, and preceded by a small rounded spot ;

scutellum with the apex testaceous.

Long. 10-12 millim.

Hab. Mexico (Bilimek, Mus. Vind. Ces.); GUATEMALA, San Gerénimo (Champion) ;

In some specimens the transverse band of the corium is entire, as in the preceding

species ; but the relative lengths of the lobes and the colour of the head prevent them

from being confused with that species. A Guatemalan specimen is figured.

6. Arocera patibulata, n. sp. (Tab. VII. fig. 17.)

Head black, elongate, lobes subequal in length, impunctate, transversely striate about centre; lateral lobes

hollowed and concave at apex. Antenne black; first, second, third, and fourth joints gradually increasing

in length, fifth wanting, third joint clavate, fourth uniformly thickened. Pronotum black, sides raised

and reflexed, with a large crucigerous prasinous fascia or disk; scutellum black, ornamented with a cru-

cigerous fascia, prasinous in colour, extending from base to apex (the apical portion much narrowed) and

fully across disk. Corium black, with a deeply sinuated basal spot, apical half irregularly defined, and

apical two thirds of claval margin prasinous. Membrane black, with the apical border white. Connexivum

alternately orange and black. Abdomen beneath orange-yellow, with a longitudinal row of transverse,

central, segmental fascie, gradually diminishing in width from base to apex, a stigmatal row of rounded

spots, a marginal segmental row of obconical spots (gradually decreasing in size from base to apex),

sternum, rostrum, and legs black.

The rostrum about reaches posterior cox, the second joint of which is the longest. Body above smooth, sub-

levigate.

Long. 12 millim.

Hab. Costa Rica, Irazu (Rogers).

Besides its very different colour and markings, the anteriorly concave surface of the

head, and the greater length of the same, are positive characters by which to separate

A. patibulata from the two preceding species.

The variety figured (from Costa Rica), besides the wider anterior and lateral borders

to the pronotum, and the reddish colour of the scutellum, has the underside of the

body uniform green, with only the margin reddish. Two varieties from Mexico in the

Berlin Museum resemble this form, but have also the disk of the pronotum and the

greater part of the corium of the same reddish hue; in these species, however, the

underside of the body possesses the red macular markings as in typical and, to judge

from their greater number and persistency, normal forms.

The typical specimen figured is from Mexico, the A. principalis, Stal, and is in the

collection of Dr. Signoret.

We now approach that portion of the subfamily Pentatomine in which the abdomen

is more or less distinctly spinous at the base. This genus possesses that character,

and has also the basal joints of the antenne longer than the head; the lobes of the

head are subequal in length.

Vulsirea is confined to the Antilles and Tropical America; of three described species

two are found in this fauna.

This genus is closely allied to the preceding, and differs principally by the length of

the first joint of the antenne, which either does not reach or only just reaches the

apex of the head. This is a Neotropical genus; and two of the three species here

included have not been recorded beyond Central America.

The figure is from a typical specimen kindly forwarded from the Stockholm Museum.

P. fasciata is closely allied to the preceding species; and its principal differential

character appears to be the length of the rostrum, which, according to Haglund, is

“multo longiore medium segmenti penultimi abdominis fere attigente.”

also the same wide range as the genus to which it belongs. It is distinguishable from

the preceding genus by the shorter rostrum, with the second joint not shorter but

Two specimens received from Costa Rica represent the typical form of the species

(Var. a, Stil). Very few observers appear to have paid much attention to this widely

spread insect. It is probable that its wide dissemination has been greatly assisted by

the winds; and the writer, on his return from India a few years since, found several of

this species which had been blown on board when more than a hundred miles south-

west of Madagascar.

This genus is closely allied to Nezwra. The body is subovate and less oblong, head

sinuated on each side, lobes of equal length, and apex rounded. This is another of

those genera in which the differences seem more apparent than real; the shape of the

body and different coloration gives Banasa a more distinct appearance from the genus

margin pale, impunctate. Corium with the basal margin narrowly pale luteous. Membrane obscure

-hyaline, pitchy at base. Abdomen above pitchy; connexivum luteous, with the apical angle of each

segment pitchy. Underside of body and legs luteous,

I submitted this specimen (one only) to the late Prof. Stal, the founder of the genus,

and the keeper of the Rhynchotal portion of the Entomological collection of the

Stockholm Museum ; otherwise I should have hesitated to describe this single example.

However, as it has been compared by Stal with his types, and by myself with those of

Dallas, there is no doubt of its nondescript character. Allied to B. varians, it is dis-

tinguished from that species by its much more elongated form and not rounded but

sinuated lateral margins of the pronotum.

The best differential characters amongst those enumerated by Stal are, perhaps,

“carina mesosterni anterius distinctius elevata, ibidem incrassata, vel plerumque lami-

nata, plerumque quoque inter coxas anticas libere prominula.” This genus has an

extremely wide range, although the species it contains are few in comparison. It is

recorded from the Neotropical, Ethiopian, Palearctic, Oriental, and Australian Regions ;

and one species, P. lituratus, Fabr., is somewhat common in England.

This is an extremely variable form. Stal remarks, “ Variat antennis pictura nigra de-

stitutis.” It also varies in size, colour, and in the amount and nature of its punctuation.

In colour it is usually luteous, sometimes varying more or less to bright pale green; and

as regards the punctuation, Prof. Uhler states, as the result of an examination of his

own series, “ Punctures and ruge are coarser or finer according to the size of the speci-

men.” This peculiarity I have not found to obtain in my own specimens or in those

examined by me.

PHALCECUS.

Phalecus, Stal, Stett. ent. Zeit. xxiii. p. 98, nota (1862) ; En. Hem. ii. p. 47 (1872).

The elevated meso- and metasternum, with the depressed body and triangular head,

of which the lateral lobes are the longest, are characters which at once denote this well-

marked genus. It is Neotropical in its habitat, but one species having hitherto been

recorded, the P. pustulatus, De Geer. A second species is now added.

1. Phalecus decoratus, n. sp. (Tab. VII. fig. 9.)

Head piceous, with lateral margins and base of central lobe luteous, margins reflexed; antenne luteous, spotted

with fuscous; first and third joints shortest, the last longer than the first; second, fourth, and fifth

subequal in length. Pronotum piceous, with the following luteous markings—one on each lateral margin,

two on anterior margin, a fainter waved broken transverse fascia across disk between lateral angles,

between which and anterior margin are five irregular spots ; lateral angles slightly prominent. Scutellum

and corium black with cupreous reflections, the first with five bright luteous spots, one in each basal angle, one

about the centre of each lateral margin, and one at the apex, central two the smallest. Corium with the basal

margin narrowly luteous, and three submarginal bright luteous spots arranged longitudinally. Membrane

fuscous. Abdomen above piceous, connexivum luteous, apical segmental margins black. Underside of body

and legs luteous ; sternum and abdomen with a broad marginal piceous band, which contains a marginal

row of luteous spots; rostrum luteous, with the tip narrowly black, about reaching the intermediate coxe.

Long. 8-10 millim.

84 HEMIPTERA-HETEROPTERA.

Hab. British Honpuras, Belize (Blancaneaux); GuateMaLa, La Tinta, Tamahu,

Pancina, and Chiacam (Champion).

Differs from P. pustulatus, De Geer, by its more linear form, the head less cleft at

the apex, the different markings above, and the abdomen not unicolorous beneath. It

appears to be a rare insect, as we have only received a single example from each of the

above localities.

BOTHROCORIS.

Brachystethus, subg. Bothrocoris, Mayr, Reis. Novara, Hem. p. 68 (1866).

Bothrocoris, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 582.

Brachystethus, Dallas (part.), List Hem. i. p. 317. 4.

This genus is only separated from the following by the shortness of the odoriferous

apertures. The metasternum has a distinct keel, which is not emarginate anteriorly nor

produced beyond the intermediate coxe. Stal writes “jugis et tylo eque longis.” I

should rather state lateral lobes a little longer than central; and “angulis lateralibus

thoracis haud productis” should rather be rendered ‘“‘not or but slightly produced.”

This genus is a Neotropical one. Only one species has hitherto been described; a

second is here added, which, though found in Central America, has also been received

from Demerara. It is probably, from the habitats of the other species, more or less a

Brazilian genus.

1. Bothrocoris fusco-punctatus, n. sp. (Tab. VIII. fig. 5.)

Ochreous, somewhat thickly covered with fuscous punctures. Head with the margins reflexed; lateral lobes

4 little longer than the central, margined with luteous or sanguineous. Antenne with the first three

‘ joints increasing successively in length, fourth and fifth subequal; first, second, and third joints ochreous,

spotted with black ; fourth black; fifth black, with basal half luteous. Pronotum with the lateral angles

obtusely prominent; lateral margins luteous or sanguineous ; and two waved black fascise on disk, a little

behind anterior margin. Scutellum with two black deeply excavated fovez at base ; membrane ochraceous ;

connexivum luteous, with the segmental, basal, and apical margins black. Underside of body and legs

concolorous; marginal border of abdomen as above.

Long. 11 millim., lat. pronot. ang. 74 millim.

Hab. Panama (coll. Dist.)—Gutana, Demerara (coll. Dist.).

Very distinct from B. quinquedentatus, Spin. Lateral angles of pronotum more

ferous apertures. The species are all confined to Tropical America.

TEMALA, San Gerdénimo, La Tinta and Sabo, Vera Paz (Champion) ; Costa Rica (coll.

Dist.), Caché (Rogers); Panama (coll. Dist.), Matachin (Schunke, coll. Oberthiir).

This is a most variable species, both in colour and punctuation. All the specimens are

more or less of the dull hue and pattern of the variety figured (which came from Yucatan),

in which the spots of the pronotum and corium become irregularly enlarged and the

last often confluent, and also possess the extremely coarse punctuation of the scutellum—

which, compared with typical and normal forms, would raise a presumption that this

variety had become constant in these characters, and must therefore be raised to specific

rank. I have, however, seen all the intermediate links, both in colour and punctuation,

including an undoubted Mexican specimen which has almost this identical Yucatan

facies, save in brightness of hue. In this species we may see the extreme of varietal

segregation, without finding any sufficient aggregate of characters to note the existence

of more than one “ species.”

PEROMATUS.

Peromatus, Amyot et Serville, Hist. des Hém. p. 156 (1843) ; Dallas, List Hem. i. p. 316.1 (1851).

The distinct keel to the metasternum, which is notched or bifid in front, agrees with

the following genus (Edessa) in at once separating both these genera from any of the

preceding. Peromatus differs from Edessa in having the antenne of four joints only,

and is a distinctly Neotropical genus.

1. Peromatus notatus. (Tab. VIII. fig. 8.)

86 HEMIPTERA-HETEROPTERA.

Hab. Guatemaa, Zapote (Champion); Costa Rica, Irazu (Rogers); Panama (Boucard).

—Braziu? 545, Para!, Minas Geraés°, Rio Janeiro’.

This species varies in the length and coloration of the pronotal spines, which are

sometimes luteous or castaneous; and the upper surface of the body is also most variable

in colour in different specimens. Of three specimens received from Central America

there is a remarkable constancy in these respects, one of which, from Panama, is

figured.

2. Peromatus robustus.

Peromatus robustus, Haglund, Stett. ent. Zeit. xxix. p. 161.11; Stal, En. Hem. u. p. 49. 3%.

Hab. Mexico1?, Vera Cruz?.

T have not seen this species. It seems closely allied to P. validus, Dall., a Brazilian

form ; and, from Haglund’s description, it must be easily recognized from the preceding

species by the obtuse spines of the pronotum not being constricted at the base and by

the colour of the antenne, “articulo primo excepto, nigris.”

8. Peromatus truncatus, n. sp. (Tab. X. fig. 1.)

Ochreous, shining; head sparingly punctured, the lateral lobes transversely striated. Pronotum sparingly

punctate aud rugulose ; anterior margin broadly smooth and impuuctate, behind which it is transversely

and much more decidedly rugulose; pronotal angles produced into short, broad, flat, obtuse processes.

Scutellum somewhat thickly punctate, and rugulose at base; corium purplish, opaque, very thickly and

finely punctured, the nervures shining luteous ; membrane dark, shining, cupreous. Body beneath ochreous,

a purplish patch at odoriferous aperture, on outer margin of which is a large shining luteous spot ; abdo-

men with a submarginal row of pitchy spots situated on segmental incisures, a faint central longitudinal

fascia, and posterior margin of sixth abdominal segment also pitchy; antenne ochreous, third joint very

long, remainder wanting.

Long. 21 millim., lat. pronot. ang. 13 millim.

Hab. Mexico (Mus. Berol.).

This small and distinct species is most closely allied to P. nodifer, West., but differs

from that species by the broad, flat and truncated angles of the pronotum. The figure

is from a specimen in the Berlin Museum kindly lent me by Prof. Peters.

EDESSA. 87

This genus differs from the preceding in having five-jointed antenne ; other differences

have prompted further generic subdivision; but the simpler and more comprehensive

view may be now said to universally obtain. This is by far the largest genus of the

Pentatomine, and occupies in the Rhynchota a position in many respects analogous to

that of the Lepidopterous genus Papilio. Both possess structural differences which have

been used in other portions of either order for generic differentiation ; both, however, are

dominated by a structure so distinct as to logically raise the genus to the position of a

subfamily, if such generic subdivision took place. dessa, however, is almost confined to

the Neotropical Region; E. bifida, Say, is a Nearctic form, but, according to Townend

Glover, has not yet been discovered north of South Carolina. |

Very little is recorded as to the habits of the Edessas. Sir Hans Sloane, in his ‘ Natural

History of Jamaica, figures a species (tab. 237. f. 15, 16) which appears to somewhat

resemble E. cornuta, Dall., and remarks that “when it is kept it turns to a dark brown

colour.” ‘The great variation in colour of the species in this genus may therefore probably

occur after death. The same author, speaking of this insect, says “‘It leaps from bush

to bush in the savannas.” The word “ flies” should be substituted here for “ leaps.”

A. Lateral angles of pronotum produced or cornuted ; apical angles of sixth segment of

second joint a little longer than the third, fifth a little shorter than fourth, which is much the longest.

Pronotum sparingly punctate, and with a faint central pale longitudinal line; anterior portion obscurely

and transversely wrinkled, verrucose near anterior margin; lateral submargins faintly transversely

striated ; lateral angles prominently and subacutely produced ; apices ochraceous, very slightly pointed and

segmental incisures and a longitudinal series of transverse linear impressions situated near stigmata

somewhat darker and greener.

Tong. 15 millim., lat. pronot. ang. 103 millim.

Hab. Costa Rica (Mus. Berol.; coll. Dist.), Caché, Irazu (Rogers).

This species, judging from Stal’s description, would seem to be closely allied to

E. sahlbergii of that author; the different colour of the abdomen above, and the

relative lengths of the second and third joints of the antenne, are sufficient, however,

to separate the two forms.

This species also appears to be confined to Costa Rica, one specimen in my own

collection, another in the Berlin Museum, and two sent home by Mr. Rogers being the

only examples I have seen. Mr. Champion has not hitherto met with it in Guatemala ;

nor have I seen it in any collection from Panama.

Head pale green, very faintly and transversely striate. Antenne pitchy; basal portion of first joint suffused

with greenish; bases of third, fourth, and fifth joints creamy white, the white increasing with the

number of the joints; second joint longer than third; fourth and fifth subequal. Pronotum green, very

faintly and sparingly punctate; lateral margins luteous, lateral angles subprominent. Scutellum green,

I have seen but one specimen of this species, which I forwarded for comparison to

the late Prof. Stal, who replied to me “ #. vinule affinis, sed distincta videtur.” I have

since, through the kindness of Prof. Lindstrém, been enabled to compare it myself with

a typical specimen of H. vinula, and find the following differential characters between

the two:—E. stalit is less elongate in form; the corium is without the “ callo levi pone

the third, remainder wanting. Pronotum green, with the anterior portion and the greater part of the

lateral borders ochraceous, moderately punctate; anterior margin transversely costate and impunctate ;

lateral angles moderately prominent, slightly recurved. Scutellum with the basal half occupied by a large

irregular ochraceous patch, which is sparingly and somewhat obscurely punctate; apical half green, and

much more finely and densely punctate. Corium testaceous, thickly and finely punctate; base of costal

margin pitchy ; a somewhat levigate spot on disk, about one third from apical margin. Membrane obscure

hyaline, fuscous at base and along costal margin. Abdomen above shining green, testaceous towards

apex. Underside of body and legs pale ochraceous.

Long. 17 millim., lat. pronot. ang. 9 millim,

94 HEMIPTERA-HETEROPTERA.

This variety is closely allied to the preceding (E. rivosa, Stal); but, besides its much

larger size, it differs also in the different colour (darker and brighter) of the abdomen

above, the slightly more recurved apices of the pronotal lateral angles, the different

colour of the corium, with the base of the costa pitchy, &c. Different as it is, however,

in colour and size, I can find no structural characters to lead me to consider that it

is any thing more than a strongly marked variety of E. rixosa; but as I have only seen

one specimen, and that has the antenne mutilated, which if perfect might give some

decisive character, I have considered it better to give it provisionally a distinct varietal

name.

Stal? erroneously considered £. sigillatus, Walk., a synonym of this species. A

Mexican specimen thus labelled, received from the Stockholm Museum, is here figured.

I cannot agree with Stal in following Erichson as regards the substitution of the name

corculum for cornuta. Itis quite clear that Klug first proposed the name cornuta,

and that it was by this author a MS. one only. Burmeister used Klug’s name, and

gave a diagnosis, thus fixing the species, and hence the name also. Erichson appears

merely to have substituted another MS. name; for in Schomb. Reis. iii. p. 610, the

species appears as E. corculum, Hoffgg. (i. mus.)—E. cornuta, Burm., and E. albirenis,

H.-S., being given as synonyms. But, as Graf von Hoffmansegg, so far as I can discover,

never published a description, the name Z. cornuta, Burm., though inapplicable to the

structure of the insect, must stand ; and as it was published in 1836, the species described

by Dallas under the same name in 1851 must change also. For this I propose the

name /. dallast. |

Hab. Mexico ?, Oaxaca ! (coll. Dist.).

A Mexican specimen in the Stockholm Museum is here figured. Stal substituted the

name albicors for this species without any explanation. It is probable that he did so

owing to the name cordigera having been used by Erichson. However, the names

though similar are not identical, and I do not consider any rules have been formulated

to allow such a change to be made on such grounds. Moreover, no writer appears

conversant with Erichson’s species ; and should it be proved ultimately to be a synonym

only, then Walker's title would have to be resuscitated.

fuscous, obscurely pilose, with the second joint considerably shorter than the third, fourth longest, fifth

about subequal in length to the third and fuscous, with the base and apex luteous, fourth also with the base

narrowly luteous; pronotal angles subprominent ; scutellum with the apical portion faintly and obscurely

sulcated. Membrane eneous. Underside of body and legs somewhat paler than the upper surface.

Long. 14 millim., lat. pronot. ang. 8 millim. .

Hab. Guatema.a, San Juan (Champion). \.

Allied to E. conspersa, Stal, but differs in having the lateral borders of the pronotum

more convex, and the apical portion of the scutellum much narrower and obscurely

furrowed ; the colour and markings are very distinct.

45, Edessa petersii, n.sp. (Tab. IX. fig. 25.)

Edessa discors, Erichs. in Schomb. Reis. ii. p. 611 ??.

Head, pronotum, and scutellum bright castaneous; corium pitchy castaneous; pronotum and scutellum

sparingly but coarsely punctate ; corium rugulose and finely punctate. Antenne pale castaneous; second

joint a little longer than the third; fourth and fifth subequal. Pronotum with the lateral margins

narrowly bright castaneous, and the lateral angles subprominent. Membrane pale eneous. Underside

of the body pale Iuteous; lateral borders of the sternum very bright castaneous. Abdomen with five

castaneous longitudinal fascie, one central, two discal, and two submarginal (the last sometimes very

indistinct). Legs pale bright castaneous.

Long. 13 millim., lat. pronot. ang. 8 millim.

Hab. Muxico (Mus. Berol.); Guatemata, San Gerénimo (Champion).

A Guatemalan specimen is figured, which agrees with several others from the same

locality in being somewhat darker in hue than a Mexican specimen contained in the

EDESSA. 99

Berlin Museum. This last form also varies in having the anterior and lateral borders

of the pronotum broadly luteous; and the underside is also brighter than in the Guate-

malan examples.

This species corresponds in many respects with Erichson’s description of E. discors,

but I have been unable to fully identify it. The words “das Halsschild mit schmalem

gelben Seitenrande,” and “Die Unterseite rothlich gelb, mit feimem dunklen Quer-

streifen,” together with the fact that Erichson placed this species before his £. abdomi-

nalis, where I also naturally included it before consulting that author’s work, are

evidence in the affirmative for its being E. discors. On the other hand, as these characters

are so loosely worded, and no size is given but “von der Grosse der A. meditabunda,”

which does not quite apply, I have thought it best, not having seen the type, and no other

author, as far as I am aware, having recognized this species, to give, somewhat

doubtingly, a new specific name, referring at the same time to Erichson’s description.

46. Edessa abdominalis. (Tab. X. fig. 2.)

Edessa abdominalis, Erichs. in Schomb. Reis. iii. p. 611’.

Ochreous, punctured and suffused with fuscous. Head pale ochraceous, with the lateral lobes transversely —

striated, punctured with fuscous, and their disks pale sanguineous. Pronotum pale ochraceous, darker

towards base, sparingly covered with dark punctures, the lateral margins narrowly sanguineous. Scutellum

ochraceous, finely and densely punctate ; punctures fuscous, and mostly confluent. Corium dark, obscure

ochraceous, thickly and finely punctate, with the base of costal margin pale sanguineous. Membrane eneous.

Abdomen above pitchy ; connexivum pale sanguineous. Underside of sternum and abdomen sanguineous,

finely, darkly, and rather thickly punctate. Head beneath and legs pale ochraceous.

Long. 124 millim., lat. pronot. ang. 74 millim.

Hab. Mexico, Oaxaca (Mus. Berol.).—Brivish Guiana!.

Closely allied to the preceding species, but not only instantly separated by the colour

of the abdomen beneath, but structurally by the scutellum, which not only differs greatly

in its punctuation, but is also much more deeply sinuated before the apical third portion,

which has its lateral margins much more convex.

Erichson’s description is very vague ; he gives no dimensions, but describes the species

as “‘ Grdsse und Form der vorigen,” which was his F. discors, and which, as before men-

tioned, he represents as “ von der Grosse der A. meditabunda.” ‘This gives an approxi-

mate idea; and “ Das Halsschild mit feinem gelben Seitenrande,” and “ Der Hinterleib

einfarbig roth,” are such well-marked characters that I feel little doubt in the identifi-

cation. “Die Oberseite hellgriin ” refers probably to a fresh specimen.

Subfam. ACANTHOSOMINAL.

Acanthosomina, Stal, Hem. Africana, i. p. 83 (1864).

Only one species of this subfamily having as yet been received or recorded from

Central America, it is scarcely necessary to make much numerical comparison of either

genera or species. Computing, however, in a general manner, according to present

knowledge, the Acanthosomine of the Nearctic and Neotropical Regions comprise about

three fourths the number of genera, and two fifths the number of species, of those

recorded in the same subfamily from Africa, Asia, and Australia.

ACANTHOSOMA.

Acanthosoma, Curtis, Brit. Ent. i. p. 28 (1824) ; Dallas, List Hem. i. p. 198 (1851) ; Stal, En. Hem.

v. p. 110.

This genus being the only one known to represent the subfamily in Central America,

the two-jointed tarsi, a character peculiar to the whole of the Acanthosomine, will at

once distinguish it. It is common to the Nearctic, Palearctic, and Oriental Regions.

Of the American species all are Nearctic, one of which, here enumerated, has also been

received from Mexico. |

It is of the European species A. griseum, Burm., that Westwood, quoting De Geer in

his ‘ Mémoires,’ gave the interesting description of the females, accompanied by their

respective broods, each consisting of from twenty to forty young, which they attended

- with as much care as a hen does her brood of chickens. In this county Mr. Hellings,

of Exeter, in 1871 (Ent. Month. Mag. vol. ix. p. 13) “ observed a female ona birch tree

on the 6th of June laying eggs; over these she brooded without moving till the 29th,

when the young bugs were hatched. On July 9th they moulted, and on the 13th

began to move off their native leaf.” According to Townend Glover, the only species

here included (A. laterale, Say) is considered by Prof. Uhler to be the North-American

representative of the above.

Uhler ® states that this species is widely distributed in Canada, British America, and

the Northern States. The specimen figured is from Mexico, and is in the collection of

Dr. Signoret, who enabled me to compare it with the North-American specimens in

the British Museum, which have been identified by Mr. Dallas as A. nebulosum. It

does not differ in any respect from these ; and I agree with Prof. Uhler in considering

Kirby’s name a synonym only of Say’s A. laterale.

Subfam. TESSARATOMINA..

Tessaratomina, Stal, Hem. Africana, i. p. 33 (1864).

The insects comprising this subfamily are found principally in the Ethiopian,

Oriental, and Australian Regions, and are also there found in their largest size and

most representative forms. The Tessaratomine form a very small addition to the

Pentatomide of the Nearctic and Neotropical Regions.

PIEZOSTERNUM.

Salica, Walker, Cat. Het. iii. p. 469 (1868).

The principal structural characters of this genus are the sternal keel produced to the

anterior coxe, the posterior margin of the pronotum produced over the base of the

scutellum, and the five-jointed antenne.

One species is abundant in West Africa; another has lately been discovered in

Madagascar ; and three others are recorded from the Neotropical Region, of which one —

only has yet been found in Central America. °

Amyot and Serville 3, in giving ‘‘ Oware (Afrique) ” as a locality for this species, have

evidently confused it with P.calidum, Fabr. Considerable variation occurs in the

apices of the lateral pronotal angles, which, though they may generally and correctly

be described as subacute, are more or less developed in that direction in different

specimens. From an examination of my own specimens I should incline to the opinion

that these gradually become more acute towards the south.

PANTOCHLORA.

Pantochlora, Stal, En. Hem. i. p. 64 (1870).

The antenne, as in the last genus, are five-jointed; but Pantochlora is at once

separated from Piezosternum by the posterior margin of the pronotum not being

produced over the base of the scutellum. But one species is known; and the genus

seems to be confined to Central America.

Only one genus of this subfamily is found in America, and that in the Neotropical

Region ; the majority of the Dinidorine are found in the Old World, and are distri-

buted much in the samé way as the previous subfamily, Tessaratomine.

Cyclopelta, Stal, Ofv. Vet.-Ak. Forh. 1867, p. 532; En. Hem. i. p. 79 (1870).

In this genus the antenne are of four joints only, the scutellum broad and rounded

at the apex, and the metasternum and abdomen unarmed. Dinidor is Neotropical in |

its habitat. Four species are recorded, of which one only is included here.

Apart from the colour-difference of the pronotum compared with that of D. mactans,

I have not been able to separate the two species by the structural characters given by

Stél. The length of the apical joint of the antenne, however, is sufficient to divide

them, being much shorter in D. rufocinctus than in D. mactans.

Fam. COREIDA.

Subfam. MEROCORINE..

Merocorina, Stal, En. Hem. i. p. 125 (1870).

This subfamily is confined to the Nearctic and Neotropical Regions. One genus is

peculiar to Central America; and of the two others which are found in this region the

majority of the species are Neotropical. Roughly computing, Central America in the

Merocorinz possesses about one fourth of the number of known genera, and about one

fifth of the number of described species.

FLAVIUS.

The head is distinctly and somewhat prominently tuberculated beneath, and the meso-

sternum prominently elevated. This elevated portion is broadest at the base, where it

is tuberculated on each side. The posterior tibie are broad. But one species is at

present known to science :-—

1. Flavius lineaticornis. (Tab. X. fig. 73,82.)

104 HEMIPTERA-HETEROPTERA.

Stal considered these sexes distinct species, on account of the wider body and tuber-

culated posterior femora of the female; this sexual difference, however, occurs also in

the next species here enumerated (Hirilcus alternatus), of which I have examined a

very large series. As regards the small yellow fascia on the posterior tibie of the

female, I detected this also, though more obscurely, in a male specimen contained in the

British Museum.

HIRILCUS.

Hirilcus, Stal, Stett. ent. Zeit. xxiii. p. 274 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 536; Hem. Fabr.

Allied to the preceding genus; but the head is not tuberculated beneath, nor is the

mesosternum prominently elevated, but more or less convex. The posterior tibie are

moderately dilated.

In addition to the species here included, three others are recorded from Brazil.

1. Hirilcus alternatus. (Tab. X. fige. 93,109.)

Meropachus alternatus, Dall. List Hem. ii. p. 420. 3}.

Meropachys alternatus, Stal, En. Hem. i. p. 125. 3.

Hab. Mexico! (coll. Sign.); Guatemaua, Teleman, Panzos, Purula, La Tinta, and

Chacoj (Champion).

This is a variable species, in the emarginate or convex apex of the scutellum, in the

colour of the apex of the last joint of the antenne, and in the colour and markings of

the connexivum. In some specimens there is a distinct black mark on each side of the

scutellum, about the middle, as described by Dallas; in others this is wanting. These

differences are not local; for the two specimens (male and female) figured are both from

Chacoj, and, together, exhibit the maximum of variation; neither can these colour-

differences be considered sexual. The strongly granulated posterior femora in the

female, with the shorter and more robust body, is similar to what is observed in the

same sex of the last genus.

Walker, Cat. Het. iv. p. 69, has blundered here with almost disastrous consequences.

He has added six specimens, 6-g, of Flavius lineaticornis to the one specimen of this

species; and as he has placed them first in the collection, they would naturally mislead

any one who consulted Dallas’s type without also referring to the description. I was

thus deceived myself ; and this may be taken as an example of the reason why, in con-

sulting and verifying the species described by Walker, I have considered it worse than

useless in most instances to accept his determination of other authors’ species, or accept

the habitats of the same.

LYCAMBES.

Pachymeria, Laporte, Ess. Hém. p. 28 (1882). .

LYCAMBES. 105

Lycambes is readily distinguished from the two preceding genera by the moderate

elevation of the mesosternum and metasternum. This raised portion is somewhat

triangular, with the basal angles on the metasternum produced into acute lobes. Of

four recorded species, one is peculiar to Central America, two to the Antilles, and one

to Brazil.

This is a protean species in coloration. Stal! thus diagnosed the varietal forms he

had observed in Mexican specimens, which seem to apply somewhat correctly to all the

Central-American forms which we have received :—

Var. a.

Testaceo-flavescens, anastomosi venarum corii nigra; femoribus extus infuscatis; serie laterali macularum

levium straminearum in disco ventris.

This variety includes the form described by Walker under the name of A. acutiusculus

(female, not male, as stated), and also the two male and female Guatemalan specimens

figured (Tab. XI. figg. 2 & 3), which have the under surface of the abdomen pale and

unicolorous. The posterior tibiee of the male are more or less fuscous at base. In all

the specimens received from Guatemala the colour of the upper surface is pale green,

more or less shaded with dull testaceous.

Var. 0.

Ut var. a, sed obscurior, thoracis macula media, scutello maculisque lateralibus pectoris interdum in vittam con-

fluentibus, stramineis.

This variety has also been received from Guatemala, and is the form described by

Walker as H. collaris. |

Var. ¢.

Nigro-fuscus, macula discoidali thoracis maculisque ventris stramineis ; hemelytris fusco-lividis.

This is the variety figured (Tab. XI. fig. 1), and is a Mexican specimen in the collection

of Dr. Signoret. It is also the form described by Walker under the name of A. gutti-

ventris, and is represented by a Costa-Rican specimen in my own collection.

The majority of the specimens I have examined, especially those from Guatemala,

appertain to the form var.a. This 1 imagine to be the original or dominant facies of

the species; and the vars. 6 and c are melanic forms which have either acquired (as is

likely in most cases) that varietal coloration during life or, as may be possible, from

much the same process observed in the genus Edessa, owe it (though much more un-

frequently) to partial discoloration after death.

Walker has not only described the three varietal forms under three specific names,

but under two different genera. What seems inexplicable, however, is, in his descrip-

tion of H. collaris, he writes “Dorsum of the abdomen black,” whilst the specimen

described, the only one in the British-Museum collection, has the wings expanded and

the upper surface of the abdomen exposed, which is bright red, with the usual luteous

markings.

CORYNOCORIS.

Corynocoris, Mayr, Reise ‘ Novara,’ Hem. p. 95 (1866) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 537.

This genus is primarily distinguished from the last by the posterior femora, which are

very slender towards the base, and in length pass the apex of the abdomen; and secon-

darily by the antenniferous tubercles being spined externally.

But two species are recorded, both of which are Nearctic. One of these, however, has

been found in Mexico, and is here enumerated.

1. Corynocoris distinctus.

Crinocerus acridioides, H.-S. Wanz. Ins. vi. p. 20, fig. 575. .

Walker, Cat. Het. iv. p. 120. 2°.

Hab. Nortu America, Northern New York to Florida?, St. Louis! 4, Colorado? ?,—

Mexico, Orizaba‘.

This species is here included on the strength of a Mexican specimen contained in the

British Museum. Prof. Uhler remarks :—“ Very variable in depth of colour, distinctness

of marking, and in the shape and proportions of the head, antenne, and legs. In Mary-

land it is often common in corners of fields adjoining woods, where the small weeds and

shrubs grow luxuriantly. It may be swept from the plants in such places as late as to

the middle of the month of October.” Townend Glover’s figure is useless’ for any

practical purpose.

Subfam. MICTINA.

Mictidida, Stal, Ofv. Vet.-Ak. Forh. 1867, p. 535.

This widely-distributed subfamily is well represented in the Nearctic and Neotropical

Regions, of which Central America may be said to contain about half the number of

genera, and somewhat more than one third of the number of species.

PACHYLIS. 107

PACHYLIS.

Pachylis, St.-Fargeau et Serville, Enc. Méth. x. p. 62 (1825) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 538.

The third joint of the antenne is widely dilated—a character which, taken with the

non-dilatation of the outer side of the posterior tibie, is sufficient to differentiate.

Pachylis from any allied genus here enumerated. This may be considered a truly

Neotropical genus.

the posterior tibize on both sides.

Four species are recorded, all of which are Neotropical, one only, according to present

knowledge, being also known as a Southern Nearctic form.

The males of this species which I have examined vary in size from that of the one

figured (Tab. X. fig. 19) to smaller specimens of only 37 millims., which last dimension is

also that of the few females which I have seen. The red bands to the posterior femora

of the males are also somewhat inconstant, as in one small specimen which I possess they

are only faintly indicated. The figure given by Townend Glover (in his somewhat inac-

cessible publication) is either that of a slight variety, or has not been sufficiently coloured

by the artist.

As described by Prof. Uhler, “ the nymph, probably in its fourth dress, is almost equally

showy, but is differently painted. Its ground-colour is dark steel-blue, velvety; the

scutellum cadmium-orange; the venter with large broad bands along the middle; the

tergum with transverse white streaks, and a row of short white lines on the middle, with

a series of carmine spots each side of the middle line, and with the femora and tibie

banded with cadmium, but with entirely blue-black antenne.” Dr. Dugés® states that

this species is found on Acacia albicans, and emits a red fluid by means of organs

which he describes and figures.

tudinal sulcation near the anterior coxe. It is also separable from Melucha by the

posterior tibiee not being outwardly dilated. Central America appears to be the home

of Mozena, as, of eleven recorded species, nine have been received from this subregion.

CAPANEUS.

Capaneus, Stal, Stett. ent. Zeit. xxiii. p. 277 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 538.

Capaneus differs from the preceding genus in the absence of the mesosternal sulcation.

The posterior margins of the pronotum are rounded, but truncated at the base. This

basal truncated portion is not wider than the base of the scutellum.

Stal (En. Hem. i. pp. 185 to 137) has divided Capaneus into five subgenera, an

arrangement I have not followed here. The genus as at present recorded contains

eight species, all of which are found in Central America.

Central America; one is a Nearctic form; and the other was described from Venezuela.

towards melanism, as occurs in some species of most of the allied genera.

4, Archimerus thoracicus, n. sp. (Tab. XII. fige. 73,82.)

Fuscous, sparingly pilose, with a dull ochraceous subapical patch to corium. Antenne with the first joint a

little longer than the second, third shortest, fourth incrassated, longer than third, but shorter than

second. Pronotum with the lateral angles strongly produced, sinuated, and terminating subacutely at

apex ; lateral margins finely denticulated, anterior third pilose and levigate ; disk strongly but sparingly

granulose. Scutellum transversely and somewhat irregularly striate. Corium somewhat densely punctate,

with the nervures prominent; membrane cupreous. Underside of body and legs concolorous; anterior

and intermediate tibie and tarsi somewhat paler.

é. Posterior femora strongly incrassated, outwardly armed with five strong spines, two of which are usually

the longest and strongest, inwardly margined by less-developed spines, and provided with two or three

obtuse tubercles above. Posterior tibie curved, slightly dilated, and armed inwardly with a spine about

one third from apex.

@. Abdomen broader and more dilated than in ¢. Posterior femora much less incrassated, and armed

internally with an apical row of spines. Posterior tibie straight and simple.

Long. 20-22 millim., lat. pronot. ang. 9-10 millim.

Hab. Guatema.a, Purula, Sinanja valley (Champion).

In the female specimens now before me all the tibie are paler in hue; and in both

sexes the bases of the femora and third joints of the antenne are sometimes castaneous.

The amount of incrassation of the posterior femora in the males is also a variable

character. The dilated pronotal angles will alone sufficiently separate this very distinct

species.

MAMURIUS.—SAGOTYLUS. 115

MAMURIUS.

Mamurius, Stal, Stett. ent. Zeit. xxiii. p. 278 (1862).

This genus principally differs from Archimerus by the produced median lobe of the

head. Only one species is known, and that at present from Mexico alone :—

1. Mamurius mopsus. (Tab. XII. fig. 15.)

Merardus, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 450; Hem. Fabr. p- 48, note (186s).

The posterior coxee are placed much closer together than in the preceding genus,

equalling in this respect the position of the intermediate coxe. The head above is

obtusely tuberculated near the inner margin of the eyes.

This is a well-represented Neotropical genus; but only two species have as yet been

received from Central America :—

1. Nematopus lepidus. (Tab. XI. fig. 10, 9.)

I have followed Prof. Uhler in considering Say’s name as the earliest for this species.

Stal (En. Hem. i. p. 174) placed it as a synonym of Spartocera fusca, Thunb.

S. confluentus varies much in the amount of its black markings. The two large

subbasal spots to the pronotum, as shown in Herrich-Schaffer’s figure, diminish in

size in different specimens, until in some they are totally obliterated. The quantity of

black coloration on the underside of the body is also inconstant. Say’s type appears to

be one of the protean forms of the species in which the scutellum is not wholly black.

In this genus the antenniferous tubercles are externally spinous, the lateral pronotal

angles spinous and acutely produced, the lateral pronotal margins are distinctly denti-

culated, and the metasternum at the outer margins of the posterior coxe is produced

into a tooth-like lobe. Five species are enumerated by Stal, all of which are Neo-

tropical: three appear to be peculiar to the Antilles; and only one has been received

from Central America :—

The lateral margins of the pronotum are entire, not denticulated, and the apical joint

of the antenne longer than the penultimate.

Of this Neotropical genus, one Mexican and two other species, received from Brazil

and Colombia, are all that are at present known.

Metopodus, Amyot & Serville, Hist. des Hém. p. 192 (1843).

The largely dilated posterior tibie, and the posterior femora armed above with

small tubercles and inwardly spined, are salient characters of this genus. Stal thus

further particularizes it—* Articulis duobus apicalibus rostri ad unum articulo secundo

longioribus.” The species which form this genus are of an extremely variable character ;

and many which have been described are doubtless of synonymic value only. However,

118 HEMIPTERA-HETEROPTERA.

none of Hope’s species is at all identical with any here referred to, as drawings of

the same have been forwarded to Oxford, and, by the kind assistance of Mr. F. E.

Robinson and Prof. Westwood, have been carefully compared with the types in the

Hopeian collection. I have myself done the same with those described by Dallas and

Walker. |

Prof. Uhler remarks :—“ This species varies greatly in size, in the shape and acute-

ness of the pronotal wings, in the number of spines of the femora, in the width and

shape of the expansions of the tibie, and in the colour of the antenne. Colossal

specimens from South Carolina and Florida measure as much as 34 millims. in length.

In the less mature state the antenne are entirely reddish cinnamomeous. Old speci-

mens are dark fuscous, powdered beneath with whitish.” These remarks cover almost

all the peculiarities of the specimens now before me, and seem to explain away the

only points raised by Stal to separate A. alata from A. declivis, Say— maxime affinis

ACANTHOCEPHALA. 119

et simillima, tibiis posticis superne distincte spinosis, articuloque quarto antennarum

fulvescente differt.” The specimens figured are from Yucatan; and fig. 24 represents

the male form described by Dallas as M. thoracicus. It will be noticed that in the

specimen represented by fig. 19 the posterior angles of the pronotum are strongly

angulated. This, however, exists in all the forms of the species, but is best seen in

those specimens in which the pronotal surface has become somewhat raised, and is a

character which, though faithfully portrayed by the artist, for these reasons possesses

no distinctive value.

Var. guatemalena. (Acanthocephala alata, Tab. X. figg. 14 & 15.)

Q. Closely allied to A. declivis, but differs principally by the greater dilatation of the posterior tibie, which

are rounded and not acutely truncated at apex.

Long. 25-35 millim.

Hab. Guatemaua, Teleman, La Tinta, Cerro Zunil, San Isidro, Las Mercedes

(Champion).

The varietal character only of this form is well shown by fig. 14, which represents a

specimen in which the outer dilatation of the right and left posterior tibiee is seen to be

asymmetrical ; the apex of the left tibia is also acutely truncated, whilst that of the

right is rounded, a character otherwise constant in three specimens before me. The

male resembles in all respects the same sex in A. declivis.

Var. panamensis. (Tab. XI. figg. 223 & 239.)

Allied to A. declivis, Say, but differs by the much greater dilatation of the posterior tibiw in both sexes, which

in the female is greater than in typical forms of A. declvis and less than in var. guatemalena.

Long. 32 millim.

Hab. Panama (Boucard).

It is possible that these two supposed varieties may prove to be local races; but at

the present time I have neither seen a sufficient number of specimens, nor sufficient

constancy in characters to warrant my forming that conclusion. Certainly the typical

forms of the species do not seem to extend further south than Mexico; but, on the

other hand, the increasing dilatation of the posterior tibie does not correlate with

decreasing latitude in habitat, as the Panama variety is intermediate in that respect

between the variety from Guatemala and the Mexican typical form.

8. Acanthocephala subalata, n.sp. (Tab. XI. fig. 20.)

3. Fuscous, faintly and obscurely clothed with ochraceous pubescence. Antenne with the first and second

joints subequal, third shorter, remainder mutilated. Pronotum with the anterior third densely pubescent,

lateral margins denticulated, lateral angles produced, with their apices subacute and their margins denti-

culated ; posterior angles moderately produced on each side of base of scutellum. Apex of scutellum pale

greenish. Membrane dark shining cupreous, of which the basal third is somewhat paler. Body beneath

concolorous, excepting fore and intermediate trochanters, bases of femora, tibie, all the tarsi, and a large

spot at odoriferous apertures, which are more or less dull ochraceous.

Fore and intermediate femora with a row of small spines beneath; posterior femora much thickened, with a

120 HEMIPTERA-HETEROPTERA.

double row of tubercles on outer surface, a row of smaller and more obscure tubercles on upper and lower

surface, and a row of spines on inner margin, of which three situated on apical half are longest. Posterior

tibie very faintly dilated inwardly, but finely denticulated ; strongly dilated outwardly, gradually widening

from base to near the middle, where they are strongly sinuated and narrowed to the apex; apices

concavely truncated.

This species varies in the more or less sinuated and angulated posterior tibie in both

sexes. Of the two specimens figured, the male represents the type contained in the

British Museum, and the female is that of a specimen received from Yucatan, which is

also strictly typical.

M. thomasii, Uhler, agrees with the specimen figured by Herrich-Schaffer under the

name of D. alatus in having the posterior tibie of the male much less angulated and

sinuated. Uhler states that after a close examination of other and darker specimens he

considers his MM. thomasit to be a pale variety of WM. granulosus; and a large series of

specimens which have passed through my hands confirms this view.

ACANTHOCEPHALA.—STENOSCELIDEA. 121

In the Costa-Rican specimens examined the antenne and fore and intermediate

tibize are pale ochraceous, not castaneous as in the Colombian forms described by Stal.

I submitted the figures here given to Dr. Aurivillius, who kindly compared them

with Stal’s type, and reported :—‘ The typical female of Metapodius bicoloripes, Stal,

agrees very well; but the male placed under this heading by St&l differs from your

figure prothorace carina media destituto et tibiis posticis vix dilatatis, marginibus

fere parallelis spinisque femorum post. intus 3-4.” As, however, Stal first described a

female specimen, with which these Costa-Rican forms agree, the male here figured,

received from the same place and at the same time, should be typical, and that after-

wards placed by Stal as such in the Stockholm Museum, and referred to by Dr. Auri-

villius as above, is probably a varietal form.

Several intermediate Neotropical genera between Stenoscelidea and Acanthocephala

exist, of which no representatives have as yet been received from Central America.

The structural differences are therefore so considerable, especially in the slender

posterior femora, that little generic diagnosis need be here given. ‘The posterior tibie

are dilated and longer than the posterior femora. This genus is also Neotropical; and

of four recorded species, only one is at present known from Central America.

Anisoscelis differs at first sight from the preceding genus by its simple antenne ; the

posterior tibiz are also dilated and foliaceous. This is another Neotropical genus (one

species has been described by Stal with doubt as from Tahiti), and is largely represented

in Central America.

1. Anisoscelis gradadia, n. sp. (Tab. XIII. fige. 1 3,2 9.)

Head ochraceous, base and a lateral streak behind each eye black. Antenne blackish or very dark olive-

green, basal joint inwardly pale green. Pronotum reddish brown, lateral margins narrowly and sub-

basal margin more broadly black, the extreme basal margin narrowly pale ochraceous; at anterior

margin are two transverse callosities, which in some specimens are concolorous, in others dark fuscous.

Scutellum dark brownish, with the lateral margins and a central longitudinal line pale ochraceous.

Corium reddish brown, with the nervures, claval, costal, and apical margins pale ochraceous. Membrane

fuscous. Abdomen above pale or dark brown, with the incisures and a spot near the lateral margins of

each segment pale ochraceous. Body beneath pale ochraceous ; legs pale greenish, with black lines;

apex of posterior femora yellow; posterior tibiee much dilated, dilatation narrowing towards apex, but

occupying rather more than three fourths of the whole length.

furthest at the base. The length of the first joint of the antenne is about equal to that

of the head, which is shorter than the pronotum.

This genus is found in the Neotropical, Nearctic, Ethiopian, Oriental, and Australian

Regions. The great majority of the species are Neotropical, about one third of the

whole number being found in Central America, to which subregion a few are peculiar.

L. concolor as extending only to the second ventral segment, whilst Mayr in his

correspondent, Mr. E. T. Earle, of Evergreen, S. C., June 1869, wrote a letter to the

department, in which he stated that he caught this insect destroying the cabbage-plant

bug, Strachia (Murgantia) histrionica.” According to Say, as quoted by Glover, the

male of this species has only two denticulations on the dilated edge of the posterior

tibie, whilst the female has three. This, however, according to my own observation, is

not constant; and in a female specimen now before me the right tibia has three denti-

culations, whilst the left one has but two.

This genus is very closely allied to the preceding. The characters on which Stal

seems to have principally relied are—the shorter basal joint of the antenne (which is

only about equal to the anteocular portion of the head) and the great length of the

fourth joint of the rostrum. Narnia is both Neotropical and Nearctic, one species being

This species, as the extent of the synonymy would indicate, is very variable in its

colour and markings. Prof. Uhler, who has had opportunity of examining fresh or

living specimens of the insect, remarks, “In the fresh full-coloured varieties the bright

orange bands of the pronotum contrast richly with the vivid steel-blue of the ground-

colour.” This variable character existing in the northern forms of the species is also

recorded from its extreme southern area. Berg examined thirty-three Argentine

specimens, and remarks upon their variability of coloration, especially on the pronotum

and abdomen.

| AMBLYOMIA.

Amblyomia, Stal, En. Hem. i. p. 171 (1870).

I have not seen an example of this genus. ‘The differences which separate Ambly-

omia from Phthia are, as described by Stal, the rounded and non-prominent lateral

angles of the pronotum, and “ pedibus posticis crassioribus, brevioribus, tibiis posticis

femoribus brevioribus, tarsisque crassioribus et brevioribus divergens.” Only one species

is enumerated, which is here included.

1. Amblyomia bifasciata.

This species is to me quite unknown; and I have been unable to see or obtain a

drawing of the type, as Dr. Aurivillius has written to me:—“ Amblyomia bifasciata

is not to be found in our Museum. The words ‘(Mus. Holm.)’ in the ‘ Enumeratio’

may be incorrect, or the type may be lost.”

In this genus the posterior margin of the metasternum is rounded, the nervures of

the membrane are numerous and reticulated, and the rostrum has the base strongly

incrassated. Probably about twelve species really belong to this genus, all of which

are Neotropical, with the exception of Spartocera diffusa, Say, which is a purely Nearctic

form of the genus, unless Prof. Uhler (Bull. U. 8. Geol. & Geogr. Surv. ii. p. 291) is

correct in considering it a synonym of S. cinnamomea, Hahn, in which case, however,

Say’s name should take precedence. Hahn’s species, with this exception, has not been

recorded north of the Brazilian subregion ; nor have I received a specimen from Central

America, though Prof. Uhler writes that it inhabits Mexico. Again, Townend Glover

(Ill. Ins. Ord. Hem. p. 68) considers S. diffusa a synonym of S. fusca, Thunb. If this

is correct, the difficulty is removed, as S. fusca is a common Central-American form.

As some error is here at least probable, I have not included Say’s insect either as a

species or variety in this fauna. Two species have alone passed through my hands,

which have been received from Central America.

Spartocera granulata, Stal, En. Hem. i. p. 178.

Hab. Costa Rica (van Patten), Volcan de Irazu(Rogers); Panama(Boucard; coll. Dist.).

The locality whence the type of this species was received is unknown. The Central-

American specimens agree well with Stal’s description. In some of the Costa-Rican

forms the colour of the pronotum is dark fuscous, a peculiarity not observed in those

received from Panama, of which one is here figured.

SEPHINA.

Sephina, Amyot & Serville, Hist. des Hém. p. 185 (1843) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p- 546.

Spartocera, Dall. (part.), List Hem. ii. p. 370 (1852).

Sephina differs from Spartocera in having the posterior margin of the metasternum

straight ; the nervures of the membrane are furcate ; the disk of the pronotum is convex,

depressed anteriorly ; and the base of the rostrum is much less incrassated.

This is a purely Neotropical genus, one species alone being recorded as just entering

the Nearctic Region. About one half of the genus is peculiar to Central America; and

the species seem to possess neither wide expanse of range nor variability of character.

1. Sephina bicornis, n. sp. (Tab. XIII. fig. 7.)

Black, lateral angles of pronotum with adjoining moieties of lateral and basal margins both above and beneath,

two discoidal pronotal tubercles, apical half of scutellum, basal margins of corium both above and beneath,

apex of abdomen above and beneath, a spot situated on apex of apical segment, base of anal appendage,

and three spots on each side of sternum, situated. near anterior, intermediate, and. posterior coxe, red,

Connexivum with a segmental row of large luteous spots, which form a marginal Series to abdomen

beneath.

Antenne pilose, first and second joints subequal in length, third shortest, and fourth slightly longest. Pro-

notum obscurely punctate, lateral margins finely denticulate, lateral angles prominent, subacute, slightly

directed hindwards, and deeply sinuate posteriorly ; discoidal tubercles obtusely subconical and moderately

prominent. Corium very faintly and obscurely punctate ; lavas more clearly and deeply punctate.

~ Long. 19 millim., lat. pronot. ang. 8 millim. .

Hab. Guaremata, Senahu (Champion).

This species is allied to S. pustudata, Fabr., and forms with that species, in the

common character of discoidal tubercles to the pronotum, a distinct section of the genus.

It differs from the Fabrician species by the much less sinuated and rounded lateral

margins of the pronotum, the less developed discoidal tubercles, and the absence of the

two discoidal spots on corium.

17*

132 HEMIPTERA-HETEROPTERA.

2. Sephina geniculata, n. sp. (Tab. XIII. fig. 10.)

Black ; pronotum with the anterior margin (narrowly), the lateral margins, apical portion of the posterior margin

and a central longitudinal fascia, apical half of scutellum, and costal margins of corium, red; a rounded

luteous spot on disk of corium, and a number of irregular spots of the same colour on membrane. Abdo-

men. above with the apical half red, connexivam with a segmental row of luteous spots. Underside of

body black, mottled with reddish; margins and lateral angles of prosternum red, a testaceous spot near

base of each coxa, and a lateral abdominal row of testaceous spots situated near stigmata. Legs black,

apices of femora and bases of tibiz luteous.

Antenne with the first and second joints subequal in n length, third a little shorter than fourth, second and third

joints strongly sulcated above.

Long. 16 millim., lat. pronot. ang. 6 millim.

Hab. Costa Rica, Cache (Rogers).

This is a very distinct form of the genus, and is not readily to be confused with any

other species. One specimen only was received from Mr. Rogers.

3. Sephina rogersi, n. sp. (Tab. XIII. fig. 9.)

Black, finely pilose ; a semicircular fascia on disk of pronotum, commencing on each side at base, a little before

lateral angles, and extending subparallel to lateral margins and narrowing and obscurely meeting a little

before anterior margin, and basal margins of corium red. Abdomen above red; connexivum testaceous,

with a segmental row of black spots. Underside of body red; rostrum, legs, anterior margin and a

transverse spot on disk of prosternum, anterior fourth of mesosternum, a large spot near posterior coxe,

abdomen with a row of broad discal transverse segmental fascie, sometimes semidivided, anal appendage

(wholly in g, base only in @ ), stigmata, and a marginal segmental row of quadrate spots black.

Antenne pilose, second joint a little longer than first, third and fourth subequal; pronotum with a few scattered

coarse punctures, the lateral margins very strongly pilose, lateral angles prominent and subacute; corium

very finely and obscurely punctate, clavus more distinctly punctate.

Long. ¢ 21 millim., 2 25 millim.; lat. pronot. ang. ¢ 7 millim., 2 9 millim.

Hab. Costa Rica, Cache (Rogers).

_ This species is allied to S. limbata, St&l, from which it differs by the more prominent

lateral angles of the pronotum, the red fascia not extending thereto, and the spotted

connexivum, &c.

I have examined Walker’s type in the British Museum, and find that it is not a

varietal form of this species, as the name and description would imply, the red fascia to

the pronotum being present, but obscure, owing to the specimen being somewhat

discoloured. As far as my experience goes, the species is quite constant in character.

The specimen figured is from Guatemala.

Division CHARIESTERARIA,

Chariesterida, Stal, Ofv. Vet.-Ak. Férh. 1867, p. 546.

Chariesterina, Stal, En. Hem. i. p. 178 (1870).

In this division, which comprises three Neotropical genera, all found in Central Ame-

rica, and one extended in its area to the Nearctic Region, the antenniferous tubercles

are produced and spined or dentate internally, the femora are spined, and the third

joint of the antennee dilated.

CHARIESTERUS.

Chariesterus, Laporte, Ess. Hém. p. 44 (1832); Stal, Ofv. Vet.-Ak. Férh. 1867, p. 546.

Chariesterus has the antenniferous tubercles very strongly produced and acuminate,

the basal joint of the antenne strongly incrassated, and the lateral angles of the pro-

notum produced and spinous. The genus is not numerous in species; but these have a

wide habitat: Rio Janeiro in the south and the United States in the north are well

authenticated localities.

1. Chariesterus alternatus, n. sp. (Tab. XIII. fig. 13.)

Brownish testaceous, finely pilose; head with a narrow basal margin and a broader longitudinal streak on

each lateral lobe black; legs luteous; antenn with the basal joint scabrous and luteous, second joint

about subequal in length to first, luteous, and narrowly and obscurely blackish at apex, third joint broadly

dilated on each side, fuscous, with the base narrowly and obscurely blackish (fourth joint wanting).

Pronotum with the lateral angles produced, distinctly spinous at apex and deeply sinuated posteriorly, and

terminating with two small and somewhat indistinct spines near posterior margin. Scutcllum with the

apex luteous. Membrane cupreous. Connexivum alternately luteous and black. Underside of body and

legs paler and redder; abdomen with the margin alternately black and luteous, and with five longitudinal

rows of black spots, one central and four lateral (two on each side). Rostrum blackish, with the apices

of the joints narrowly luteous.

I have examined an extraordinary specimen of this insect, contained in the Vienna

Museum, in which the antenne are asymmetrical, the left antenna having the third

and dilated joint completely absent. One specimen from Guatemala has the underside

covered with white pubescence, a character which, as seen in the previous species,

appears to be either purely varietal or else absent by being frequently rubbed and

worn off. 7

A Mexican specimen in the collection of the Berlin Museum is here figured.

PLAPIGUS.

Plapigus, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 473; ib. 1867, p. 546.

Plapigus differs principally from Chariesterus by the head being furnished with a

distinct callosity near the eyes; the antenniferous tubercles are much less produced,

and the apices are not acuminate; the basal joint of the antenne is only moderately

incrassated, but thickened near the apex, and is longer than the second joint.

Only one species is at present known from Central America.

1. Plapigus circumcinctus. (Tab. XIII. fig. 14.)

Plapigus circumcinctus, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 473. 3°; En. Hem. i. p. 179. 5°.

Hab. Mexico 12 (Mus. Berol.), Orizaba (Bilimek, Mus. Vind. Ces.); GuaTeMaa, San

Isidro, Chiacam, Panima (Champion).

The type in the Berlin Museum, which I have examined, has the head, as described by

Stal, luteous. This I believe to be a variable character, as a Mexican specimen in the

Vienna Museum, and a long series from Guatemala, one of which is here figured, have

the head either black, or more or less clothed with yellowish pubescence.

STALUPTUS.—MADURA. 135

_ STALUPTUS.

Staluptus, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 473; ib. 1867, p. 546.

This genus differs from the preceding in having a distinct collar to the thorax, and

the first and second joints of the antenne subequal in length. The anterior angles

of the pronotum are moderately and subacutely produced. But one species is at

present recorded.

1. Staluptus marginalis. (Tab. XIII. fig. 15.)

Coreina, Stal, En. Hem. i. p. 180 (1870).

Corearia, Stal, En. Hem. ii. p. 37 (1873).

In this division the characters relied upon by Stal are—‘ Spiraculis fere eque longe

a basi et ab apice segmentorum ventris vel saltem ab apice quam a basi nunquam

duplo longius distantibus.”

This is the largest group of the Neotropical Coreine. A few of the genera are

found in the Nearctic Region; and about three fifths of the whole number are recorded

from Central America.

MADURA.

Madura, Stal, Rio Jan. Hem. i. p. 35 (1860); Ofv. Vet.-Ak. Forh. 1867, p. 547.

This genus at present comprises three species—one from Rio Janeiro, another from

Venezuela, and a third from Mexico. It is more than probable that many other

species exist, and that the habitat of those described may be more extensive, as from

their small size these insects can be readily overlooked. One of the principal charac-

teristics of the genus is the long antenne, with the basal joint clavate and the fourth

very incrassate.

1. Madura perfida., (Tab. XIII. fig. 16.)

_ Chelinidea, Uhler, Proc. Ent. Soc. Philad. ii. p. 8365 (1863).

Xiphares, Stal, Ofv. Vet.-Ak. Forh. 1867, p. 551.

This distinct and peculiar genus is at once recognized from all its congeners by the

length of the head and that of the pronotum being equal, as in the Mexican species,

or subequal in length as in the Nearctic form described by Prof. Uhler, which two

species at present are alone recorded. The body is broad and ovate.

ACIDOMERIA.

Acidomeria, Stal, En. Hem. i. p. 182 (1870).

The head is triangular, a little longer than broad, with the central lobe prominent ;

the apical angle of the corium is somewhat produced, and the apical margin sinuated ;

the femora are armed with one or two spines beneath; and the body is subovate.

Four species have been described by St&l as belonging to this genus—one from

Uruguay, two from unknown localities, and the other from Mexico. It is probably

a truly Neotropical genus. I know of no record of it from the Southern Nearctic

Region.

MARGUS.

Margus, Dallas, List Hem. i. p. 523 (1852) ; Stal, Ofv. Vet.-Ak. Férh. 1867, p. 549.

Margus is distinguished from Acidomeria by the corium having the apical margin

straight and the apical angle not produced. The nervures of the membrane are

reticulated. This is another Neotropical genus, of which about a dozen species are

known; three of these are found in Central America, of which one also extends its

area to the Southern Nearctic Region.

Catorhintha, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 470; ib. 1867, p. 549.

The area of this genus is both Nearctic and Neotropical, apparently extending from

the southern portion of the first region to about the Amazonian subregion of the latter.

The ocelli are separated from each other by about twice the distance that divides

them respectively from the eyes; and near the last the head has a distinct callosity.

The body is linear or suboblong.

Ficana was founded for the reception of one Mexican species. It is closely

allied to the preceding, as Stal observes, “ Hoc genus Catorhinthe est maxime affine,

differt capite longiore, bucculis paullo brevioribus, rostro longiore, coxas posticas

attingente.” It is at least doubtful whether the institution of this genus will prove

of much classificatory value.

A Mexican specimen is figured, contained in the collection of the Berlin Museum,

and represents the typical form of the species, in which the last joint of the

antenne is luteous. To this was attached the MS. name indagator. A varietal form,

however, seems most abundant, in which the apical joint of the antenne has only the

apex luteous. This form is also contained in the Berlin Museum, and was sent to me

labelled scrutator.

CIMOLUS.

i. p. 188, note (1870).

Cimolus differs at once from the two preceding genera by the more ovate body. The

rostrum is short, scarcely passing the anterior coxe, the first joint being only about half

the length of the head. It is very closely allied to the following genus (Anasa). Two

species are at present recorded—one from the Nearctic Region, the other from Central

America.

This species differs much in the shade of coloration, some specimens, especially those

from Guatemala, being almost black above; these have also the lateral margins of the

pronotum less denticulated. This last character is not, however, sufficiently uniform to

warrant me in considering it specific, the difficulty being increased by one female

Guatemalan specimen having the rostrum a little longer than is usual in the genus,

while it differs in no other respect from other specimens of this species.

The specimen figured is a typical Mexican one in the collection of Dr. Signoret.

This genus principally differs from the preceding by the greater length of the rostrum,

the first joint of which reaches, or nearly reaches, the base of the head. Its area extends

from the southern portion of the Nearctic, throughout the whole Neotropical Region.

It is well represented in Central America.

I include this species in the Central-American fauna on the authority of Dallas 5 and

Uhler?®, The last author also gives the name of L. Provancher as a recorder of this

insect near Quebec, and likewise states that it is found in Brazil. I have, however,

seen no specimens from that region, nor have I been able to find any other reference to

the same. Ubhler’” remarks that southern and western individuals occasionally exhibit

a wonderful degree of variability in the shape of the pronotum, and that “specimens

occur which have the lateral margins of that part either distinctly sinuated, with the

-humeri quite prominent, or the reverse, with the sides bowed and the humeri broadly

rounded.” This would almost appear to apply to the characters relied upon by Stal for

the separation of the following species, A. whleri. The same author critically and well

remarks on the variation of the “size of the punctures of the surface in conformity with

its own dimensions—those which are largest being most coarsely punctured, while those

which are smallest are the most finely punctured.” I have myself observed this in the

Cydnine.

This is the destructive insect known throughout the United States as the “‘ Squash-

bug,” owing to its depredations on the squash-vines. It is for these qualities that its

habits have been studied; and we know as much of its life-history and economy as we

do at present of any other American Heteropteron. According to Glover the eggs are

“said to be round, flattened on sides, and of a metallic brown colour, deposited in little

patches, fastened with a gummy substance to the underside of the leaves of squashes

and other Cucurbitacee, in June, July, &c., until late autumn. These eggs are not all

deposited at one time on the plants, but in successive broods, during the whole season.

The larve, pup, and perfect insects all indiscriminately attack the leaves and cause

them to wither up by sucking out the sap, and appear to poison the foliage. They

moult their skins several times before attaining the perfect or winged state, and become

more oval in form as they grow older ; and as successive broods throughout the summer

they do much injury to squash- and pumpkin-vines. These insects sometimes collect in

ANASA. 141

masses around the stem near the earth, and injure the plant itself by extracting its sap

with their piercers. They also give out an odour similar to that of an overripe pear.”

On this point Prof. Verrill has found, with the assistance of Prof. Johnson, of Yale

College, that the odour of this and other hemipterous insects bears the most resemblance

to that of the formate of oxide of amyl, or the formate of amylic ether (Proc. Bost. Soc.

Nat. Hist. xi. p. 160). The perfect insect hibernates during the winter, according to

Jaeger, “in the crevices of houses, walls, and the bark of trees ;” and Prof. Uhler? relates

it being found beneath rubbish on one of the farms in Colorado in the month of August.

The last author states that “in the larval stage they are often guilty of cannibalism ;

the stronger ones sucking the juices of the weaker, and leaving only their dried empty

skins to attest their places upon the squash-vines.”

Hab. Mexico 1.

It is at least questionable whether this species is not included by Prof. Uhler as a

variety of A. tristis. Stal describes A. whleri as having the posterior lateral margins of

the pronotum obtuse, not sinuated; and, as already quoted, Prof. Uhler remarks upon

this peculiarity in varietal forms of the other species. However, Prof. Uhler wrote

subsequent to the publication of Stal’s description ; and as he is clearly quite conversant

with the writings of that author, and does not treat A. whleri as a synonym of J. tristis,

I have, though unable to examine a large series of specimens of the common North-

American insect, treated the two forms here as distinct species.

This is not only a variable species in size, but also in the colour of the upper surface

of the abdomen, which, as remarked by Stal, and strikingly exemplified by a large

series of Guatemalan specimens, is sometimes testaceous and often black with two pale,

somewhat obsolete discal spots. The apical joint of the antenne is either totally

ochraceous, as in all the Guatemalan specimens examined, or, according to Stal, the apex

only is of that colour.

to the pronotum, between the lateral spines and the posterior angles.

VILGA.

Vilga, Stal, Ofv. Vet.-Ak. Forh. 1859, p. 474.

Centrocoris, Fieber, Eur. Hem. p. 60 (1861).

This peculiar and interesting genus, founded by Stal for the reception of Clavigralla

acanthion, Dall., a species received from Para, is here augmented by a second Neotropical

species, in which the somewhat abnormal characters are even more pronounced. These

characters, distinguishing it from Zicca, are principally and superficially the spinous

condition of the basal joint of the antenne, of the lateral margins and angles of the

pronotum, the margins of the abdomen, and femora.

A third and Palearctic species is known from the Persian subregion.

1. Vilga dallasi, n. sp. (Tab. XIV. fig. 16.)

Pale fuscous; second and third joints of antenne, tibie, and tarsi pale ochraceous. Basal joint of antenne

incrassated and strongly spined; first and second joints subequal in length, second shorter than third,

fourth shortest and thickened. Head furnished with a long slightly recurved spine on each side, a little

behind the insertion of the antenne. Pronotum with the lateral angles acutely produced and armed with

strong spines on each side, several like spines on each lateral margin and two on disk. Costal margins of

corium and connexivum spinous, the last most strongly so. Femora spinous; tibie serrated. Rostrum

just passing intermediate coxe.

Long. 9-10 millim.

COLLATIA.

Collatia, Stal, Stett. ent. Zeit. xxiii. p. 298 (1862); Ofv. Vet.-Ak. Férh. 1867, p. 547.

Collatia differs from Zicca in having the basal joint of the antenne shorter than the

second. The pronotal angles are ampliated and sinuated.

Three species of this genus are now described, all of which are from Central America,

1. Collatia emarginata. (Tab. XIV. fig. 14.)

Collatia emarginata, Stal, Stett. ent. Zeit. xxiii. p. 298. 163*; En. Hem. i. p. 199. 17.

Hab. Mexico'?; Guatema.a, Capetillo, Cubilguitz (Champion).

The figure is from a typical Mexican specimen in the collection of the Stockholm

Museum.

2. Collatia jubata, n. sp. (Tab. XIV. fig. 15.)

Collatia emarginata, Stal, var. ?

Closely allied to C’. emarginata, Stal, but differs by the more elongate body and the greater elevation of the

central longitudinal ridge to pronotum. The apex of the scutellum is not pale luteous, but apparently

eoncolorous.

Long. 9 millim.

_ Hab. Muxico, Orizaba (Bilimek, Mus. Vind. Ces.).

I have described this species from a single specimen in the Vienna Museum with

considerable hesitation, as, though the structural differences between it and C. emargi-

nata are considerable, as the artist has fully shown in the two figures, I have observed a

tendency in Guatemalan specimens to vary in this particular, and shall not be surprised

if eventually it prove to be but a varietal form. In the absence of intermediate forms,

I have been compelled to separate it.

3. Collatia divergens, n. sp. (Tab. XIV. fig. 17.)

Above luteous, more or less covered with brownish punctures. Antenne with the first joint pale luteous,

second and third joints somewhat darker, particularly at apices; apical joint testaceous; first and third

joints subequal in length, second longest. Head obscurely punctate, with the central lobe somewhat raised

and prominent. Pronotum somewhat thickly covered with brownish punctures ; lateral margins (which

are strongly spinous) and a raised central longitudinal ridge on anterior portion of disk pale luteous ;

lateral angles produced, their apices terminating in acute spines, which are slightly directed upwards and

forwards, deeply sinuated behind. Scutellum with the basal half sparsely punctate, from which it is

densely and darkly punctate to the apex, which is pale and levigate. Corium somewhat thickly covered

with brown punctures, excepting about middle, where it is obscurely levigate, almost indicating a pale

transverse fascia. Connexivum pale luteous, with a series of large subquadrate brown spots, which are

spotted with fuscous on margin. Underside of body pale luteous, with two small transverse streaks

between posterior coxe, two small rounded spots on disk of second segment, two transverse oblong spots

on disk and basal margin of third segment, a small round spot on sides of fourth and fifth segments,

and abdominal margin with a row of obscure spots, fuscous. Legs luteous; apices of femora pale testa-

ceous ; cox and bases of femora with a few fuscous spots; tibie spotted with testaceous; rostrum about

reaching posterior coxe, with the apex pitchy.

Long. 9 millim.

COLLATIA.—CEBRENIS. | 149

Hab. Mexico (Bilimek, Mus. Vind. Ces.).

This species differs from the two preceding in the acutely pointed and forwardly-

directed lateral angles of the pronotum. In most other respects it is closely allied to

C. emarginata. |

NIROVECUS.

Nirovecus, Stal, Ofv. Vet.-Ak. Férh. 1859, p. 454.

One species of this genus is alone known at present, and appears to be peculiar to

Central America. |

It is at once distinguished from the preceding genus (Col/atia) by the non-prominent

lateral angles of the pronotum. From the following genus (Cedrenis) it is separable by

the spinous condition of the posterior femora.

1. Nirovecus claviger. (Tab. XIV. fig. 18.)

Nirovecus claviger, Stal, Otv. Vet.-Ak. Férh. 1859, p. 455. 11; En. Hem. i. p. 199. 1.

Hab. Mexico (Mus. Berol.1); Guaremata, Capetillo, Duefias (Champion).

A Guatemalan specimen is figured which entirely agrees with a typical Mexican one

in the Berlin Museum.

CEBRENIS.

Cebrenis, Stal, Stett. ent. Zeit. xxiii. p. 298 (1862); Ofv. Vet.-Ak. Forh. 1867, p. 548.

This appears to be a truly Neotropical genus; of six described species three are found

in Central America, two of which, as at present known, are peculiar to that region. The

posterior femora are unarmed; and the fourth joint of the antenne is incrassated and

shorter than the preceding.

I have here figured a Guatemalan specimen, Herrich-Schaffer’s figure being some-

what misleading in not having the pronotal angles prominent. This character also

applies to the most southern form of the species, as Prof. Berg ° remarks, “ Los angulos

laterales del pronoto son mas puntiagudos que los de la imagen.” The colour is also

different.

Hab. Mexico!; GuatEema.a, Capetillo, San Gerénimo (Champion).

The figure is that of a Guatemalan specimen, which only differs from a typical Mexican

one in the Stockholm Museum by the irregularly clouded base of the pronotum.

8. Cebrenis modesta, n. sp. (Tab. XIV. fig. 21.)

Pale ochraceous, coarsely punctate. Antenne with the second and third joints longest and subequal in length,

fourth darkest and incrassated. Pronotum with the lateral margins and an obscure central longitudinal

levigate impression, apex of scutellum, lateral margin of corium, underside of body, and legs luteous.

Abdomen above red, with some fuscous spots about centre of disk. Rostrum concolorous, slightly passing

intermediate coxe.

Long. 9 millim.

Hab. Guatemata, Capetillo, Guatemala city (Champion).

This species is allied to C. robusta, but differs from that species by the narrower form

of the body, the straighter and less sinuated margins of the pronotum, the different

colour of the upper surface of the abdomen, &c. In some specimens the disk of the

corium is paler in hue, somewhat indicating a transverse fascla—a varietal character

exhibited in many allied genera.

HYPSELONOTUS.

Hypselonotus, Hahn, Wanz. Ins. i. p. 186 (1831) ; Amyot & Serville, Hist. des Hém. p. 241 (1848) ;

Dallas, List Hem. ii. p. 450, 1852; Stal, Ofv. Vet.-Ak. Foérh. 1867, p. 548.

Hypselonotus differs from Cebrenis in having the third and fourth joints of the antenne

subequal in length, and the thorax provided with a distinct collar.

This is another purely Neotropical genus; and most of the described species are found

in Central America. In a systematic sense the genus is an unsatisfactory one, the

differenti specifice being mostly of colour and markings, good structural differences

being apparently absent; but if a broader view be taken, Hypselonotus is a genus still

remaining in a plastic condition, its species exhibiting a constancy of character which

is superficial rather than structural.

The species described by Walker, Cat. Het. iv. p. 144. 23, under the name of

Hypselonotus armatus is merely a Mexican specimen of the genus Nematopus, which

has been previously figured in this work.

1. Hypselonotus punctiventris. (Tab. XIV. fig. 23.)

Hab. Mexico! ?,Valladolid, Yucatan (Gaumer); GuaTEMALA, San Gerénimo (Champion).

The type in the collection of Dr. Signoret is here figured. This is a very variable

species: in the Guatemalan specimens now before me the longitudinal black strie of

HYPSELONOTUS. 151

the pronotum are absent, or only obsoletely indicated ; the apical joint of the antenne

in some specimens is almost completely fulvous; and in others the apex of the apical

joint of the rostrum is alone black. The most distinctive and constant character is

the series of black spots to the body beneath ; and even these are sometimes somewhat

indistinct.

2. Hypselonotus intermedius, n. sp.

Head luteous, with two short fuscous streaks in front of ocelli, and a spot of the same colour behind

eyes. Antenne fuscous, lower margin of basal joint and bases of second and third joints luteous;

second joint much the longest; first, third, and fourth joints subequal in length. Pronotum with the

lateral margins narrowly fuscous, the base with a broad margin of brown punctures, and with a central

obscure longitudinal levigate impression. Scutellum brown, lateral margins and a central longitudinal

line luteous, the brown portion punctate. Corium brown; nervures, claval margin, and a transverse

fascia a little before apex luteous. Abdomen above testaceous; basal angles, a large spot on each side of

fourth and fifth segments, apex, and anal appendage black. Connexivum testaceous, with a series of sub-

quadrate black spots. Underside of body and legs pale greenish or luteous, a rounded spot on coxe, a

transverse streak on disk and near apical margin of third, fourth, and fifth segments, and annulations to

femora and tibie black. Rostrum reaching posterior coxe, black, with the basal joint luteous.

Long. 13-14 millim.

Hab. GUATEMALA, San Gerénimo (Champion).

H. intermedius differs from H. punctiventris by the different-coloured rostrum,

different black markings beneath, and is intermediate between that species and

H. lineatus. It appears to be peculiar to Guatemala, and has only been sent from

San Gerénimo. Two forms have been received—one as described, and the other with

brownish markings darker in hue, and the transverse fuscous streaks on the underside

of the abdomen also larger and darker. These differences are not sexual; nor can they

be seasonal varieties, as they were collected by Mr. Champion at the same time.

3. Hypselonotus lineatus. (Tab. XIV. fig. 24.)

This species is here inserted on the authority of Mr. Dallas, who has given the habitat

Mexico to an undoubted specimen of the species. It is a most variable species; and the

specimen figured represents the H. bilineatus, Hope, which is also the Mexican form in

the British Museum.

This is a most variable species; but in all the specimens which I have examined the

scutellum is testaceous, and the central levigate line to the pronotum always present.

In some very dark specimens the femora are fuscous; but they are usually testaceous.

7. Hypselonotus atratus, n. sp. (Tab. XIV. fig. 27.)

Black; head red, with a basal black band above; pronotal collar, a large sublunate fascia to pronotum, com-

mencing at lateral angles and continued along lateral margins, and meeting on disk a little before anterior

margin, costal margin of corium, excluding apex, and two broad fasciz on disk of corium, placed trans-

versely, truncate above and rounded beneath, but not quite meeting, luteous. Body beneath testaceous ;

base of prosternum, base of and central fascia to meso- and metasternum, basal fascie to disks of abdominal

segments, and legs, excluding coxe, black; prosternal collar, bases of pro-,meso-, and metasternum, and

discal apical halves of abdominal segments pale luteous. Rostrum black. Abdomen above testaceous,

+ apical third more or less black. Joints of antennz subequal in length, or third somewhat shortest.

Long. 12 millim.

HYPSELONOTUS.—SPHICTYRTUS. 153

Hab. Costa Rica, Irazu, Cache (Rogers).

This species differs from H. concinnus by the black scutellum, absence of central

levigate line to pronotum, colour of the legs, and black markings beneath, and appears

to take the place of Mr. Dallas’s species in Costa Rica.

8. Hypselonotus proxima, n. sp.

Above black; head, a broad central longitudinal fascia to pronotum and scutellum, on pronotum joining a

transverse fascia near anterior margin, which is abruptly deflexed on each side, and continued as a narrow

submarginal fascia to near base, apical margins of clavus and corium luteous. Underside of body luteous,

with a spot on each side of base of head, three longitudinal series of spots on each side of sternum (one at

cox and two lateral), five longitudinal series to abdomen (one central and two lateral on each side), and

two spots on abdominal margin at apices of third and fourth segments black. Femora luteous, strongly

annulated with black; tibie and rostrum black, tarsi fuscous, with the two apical joints paler. Antenne

black, with the first, second, and fourth joints subequal in length, third a little shorter. Pronotum and

corium finely but sparsely punctate, scutellum finely transversely striate.

Long. 12-13 millim.

Hab. Costa Rica, Irazu, Cache (Rogers); Panama (Boucard).—Amazons, Pebas (coll.

Dist.).

This species is very closely allied to H. linea, Fabr., and in colour and markings

above is inseparable. It is, however, at once distinguished by the spots to the body

beneath, and by the much greater length of the basal joint of the antenne than exists

in the Fabrician species. In a Panama specimen the longitudinal series of spots to the

sternum have become confluent and linear, the extreme apex of the corium being black.

SPHICTYRTUS.

Sphictyrtus, Stal, Ofv. Vet.-Ak. Foérh. 1859, p. 462; ib. 1867, p. 548; Berg, Hem. Argent. p- 88

(1879).

This genus is Neotropical, and fairly represented in Central America. Its most

striking characteristics are the acute posterior angles of the metasternum. The rostrum

reaches or passes the posterior coxe, as defined by Stal, or the intermediate coxe only,

as proposed by Berg.

154 ' HEMIPTERA-HETEROPTERA.

The Panama specimen figured here is evidently but a variety of this species, having

the scutellum wholly luteous, instead of having only the basal half either that colour

or reddish, as described by Stal and well illustrated by specimens in my own collection.

The bright blue of the pronotum is a common varietal character in all the green

species of this genus.

3. Sphictyrtus longirostris, n.sp. (Tab. XV. fig. 2.)

Green; antenniferous tubercles, anterior third and basal fascia of head, a transverse linear callosity near

anterior margin of pronotum, posterior margin of pronotum, and underside of body red; antenne,

anterior lateral margins, apex, and central portion of head, rostrum, and legs black; prosternum with

the anterior margin, lateral and posterior margins (excluding lateral angles), and a narrow fascia near

anterior coxse, mesosternum with a central waved fascia and narrow posterior margin, metasternum with

a central fascia, and apical margins of abdominal segments, dark bluish and, excepting lateral margin of

prosternum, margined with luteous. Membrane black, opaque. Pronotum and corium thickly and finely

punctate, scutellum transversely striate. Rostrum reaching apex of fourth abdominal segment.

Long. 24 millim.

Hab. GuatEeMaa, Duefias (Champion).

The large size of this species and the length of the rostrum will separate it from

S. fasciatus, to which it has considerable resemblance in colour and markings.

Sundarus, Amyot & Serville, Hist. des Hém. p. 202 (1843).

This genus is at once separated from the preceding by the non-acute posterior angles

of the metasternum. It is confined to the Neotropical Region, but is well represented

in Central America.

Discogastraria, Berg, Hem. Argent. p. 88 (1879).

The characters relied upon by Stal for the determination of this division are, “ Spi-

raculis ab apice quam a basi segmentorum ventris saltem duplo longius remotis.” Of

six genera which are now included in the Discogastraria only one has been received

from Central America.

SAVIUS.

Savius, Stal, Rio Hem. ii. p. 58 (1862) ; Ofv. Vet.-Ak. Férh. 1867, p. 550.

This genus is easily recognized by a peculiar and distinct character from all its.

congeners “Disco ventris utrinque ruga longitudinali callosa terminato.” Of three

described species two are peculiar to Central America, the third has been received from

Southern Brazil.

The American Alydaria, as at present known, comprise about one fourth of the

whole number of genera and probably about one half the number of species which are

included in this subfamily. Of four genera three are Neotropical and one Nearctic; of

the former, two are found in Central America.

These are the Alydida propria of Stal (Ofv. Vet.-Ak. Forh. 1867, p- 542), which he

Tivarbus, Stal, Ofv. Vet.-Akad. Forh. 1859, p. 458.

This genus is easily separated from the following and only other genus of the

Alydaria here enumerated by the posterior tibie having the apices produced into

distinct spines.

Hyalymenus is divided into two sections by the corium being either pellucid or sub-

opaque; and it is only of this second division that we have as yet received examples

from Central America. The majority of the species are Neotropical.

This is a most variable species—as Stal remarks, “‘species quoad magnitudinem,

colorem, picturam dorsi abdominis ventrisque, nec non formam pedum posticorum

maxime varians.” In the most melanic forms the antenne are ochraceous, the apical

joint being sometimes somewhat darker but always annulated with luteous near the base.

In all the pale-coloured varieties the sternum is ornamented on each side near the cox

with large luteous levigate spots—a character which, with the colour of the antenne,

has been used by Stél® as a sectional character for the genus; but in the melanic

specimens these sternal spots are obsolete; and therefore little differential aid is thus

afforded.

The apices of the posterior tibie are unarmed, a character which, as previously

remarked, distinguishes Alydus from Hyalymenus. Stal has divided Alydus into four

subgenera, most of which have been adopted by Prof. Uhler as genera. Neither of these

methods has been here followed. The genus as at present defined is well represented

both in the Nearctic and Neotropical regions.

Examples of this species have been sent home by Mr. Champion from Guatemala.

As Prof. Uhler remarks, it is the most closely related to A. calcaratus, Linn., of

Europe; “but in all the specimens of the European insect which I have yet seen the

collum of the prothorax is very short, and the disk of the pronotum more robust and

flattened than in our species.” I have, on the authority of the same writer, placed

A. ater, Dall., as the female and therefore synonym of this species. Townend Glover,

evidently deriving his information from the same source, states that A. eurinus “ occurs

in late summer and autumn, sometimes in great numbers, on golden-rod and other

herbaceous plants growing rankly near the edges of woods, also on Rhus glabra

(smooth sumach).”

2. Alydus femoralis, n. sp. (Tab. XV. fig. 9.)

Ochraceous, pilose, mottled and punctured with brown. Antenne ochraceous; first, second, and third joints

subequal ; fourth longest, somewhat incrassated, black, with the base broadly luteous. Head with the

lateral margins from eyes to insertion of antenne, and a central longitudinal line, pale ochraceous ;

between eyes and surrounding ocelli transversely black. Pronotum with the lateral margins and a faint

central longitudinal line pale ochraceous ; lateral angles moderately produced, apices fuscous. Scutellum

very coarsely punctate, with the apex paler. Corium with the lateral margin pale ochraceous; inner

apical margin sanguineous. Abdomen above black ; connexivum with a row of subquadrate luteous spots.

Underside of the body very pale ochraceous; head beneath with the lateral margins, a central longitudinal

line, and two linear and elongated marks on each side at base black. Sternum with the disk blackish ;

the lateral margins coarsely punctate, with a double series of obscure fuscous linear spots (in some speci-

mens these are barely visible), Abdomen punctate, a double series of transverse black spots on disk of

second segment, a single series of the same at base of third segment, and a prominent black spot on each

side of disks of remaining segments. Legs pale ochraceous, spotted with fuscous; posterior femora with

the apical halves fuscous, annulated with ochraceous; rostrum ochraceous, with the apex pitchy. Posterior

femora armed with about four strong black spines.

Long. 11-12 millim.

This division, distinct from the Alydaria by the slender and unarmed femora, and

TRACHELIUM.—CYDAMUS. 159

with the second joint of the rostrum usually distinctly longer than the two apical joints

taken together, is at present represented by four genera in Central America. The

Neotropical and Nearctic regions possess five genera of Micrelytraria, four of which

are peculiar to the first. But three genera are recorded from the Ethiopian, Oriental,

and Australian regions.

TRACHELIUM.

Trachelium, Herrich-Schiffer, Wanz. Ins. ix. p. 274 (1851); Stal, Ofv. Vet.-Ak. Férh. 1867,

p. 542; En. Hem. iii. p. 88 (1873).

In this genus the basal joint of the rostrum is shorter than the head, which, from the

eyes, is elongated, straightened, and narrowed to the base. The lateral angles of the

pronotum and the apex of the scutellum are strongly spinous. Only two Brazilian

species have hitherto been recorded ; a third, from Guatemala, is here described.

1. Trachelium albo-apicatus, n. sp. (Tab. XVI. fig. 2.)

Pale fuscous. Antenne with the three basal joints subequal and concolorous ; fourth longest, white, with the

apical half black ; apical margin of corium levigate and white, with the apical angle black. Underside

of body concolorous; a white levigate spot near hind cox; disk of third and whole of fourth segments

of abdomen luteous, with the apical margins black. Legs concolorous; apical joints of tarsi dark fuscous.

Head distinctly punctate. Pronotum coarsely punctate and subgranulose, with a levigate callosity near

anterior margin and a central raised longitudinal line; lateral spines long, slender, subacute, and suberect.

Scutellum coarsely punctate, with the apex produced into a long, slender, erect spine, slightly inclined

backwards. Clavus and costal margin of corium thickly and coarsely punctate, and a few scattered coarse

punctures on disk of corium. Connexivum concolorous, with some marginal subquadrate fuscous spots.

Long. 11-12 millim.

Hab. Guatemata, San Gerénimo (Champion). —

CYDAMUS.

Cydamus, Stal, Rio Hem. i. p. 33 (1860); Ofv. Vet.-Ak. Férh. 1867, p. 542; En. Hem. iii.

p. 88 (1873).

Cydamus has the basal joint of the rostrum as long or longer than the head, and also

differs from the preceding genus in not having the head elongated, straightened, and

narrowed behind the eyes. The lateral angles of the pronotum are produced and

spinous.

This is a purely Neotropical genus; and the following species here described is at

present its most northern representative.

1. Cydamus borealis, n. sp. (Tab. XV. fig. 11.)

Pale ochraceous, punctured with fuscous. Antenne concolorous; apex of the first and apical joint (excluding

base) fuscous ; basal joint slightly passing apex of head; second and third subequal, together about

equalling the length of the fourth joint. Head and pronotum with two central longitudinal series of

dark punctures situated a little apart. Pronotum with a few more scattered punctures on disk, and an

obscure submarginal series of the same on each side; lateral-angular spines slender, pale, suberect,

160 HEMPITERA-HETEROPTERA.

acute, with the apices fuscous. Scutellum with the basal angles fuscous, a central longitudinal linear series of

dark punctures, and with the apex produced into an obliquely erect, slender, acute, fuscous spine. Corium

sparingly but somewhat coarsely punctate ; membrane bronzy. Underside of body and head pale ochraceous,

thickly covered with dark punctures; disk of sternum fuscous; abdomen with a central and two sub-

marginal obscure and subobsolete pale lines. Rostrum reaching posterior cox, with the apex black.

Legs pale ochraceous, spotted with fuscous.

Long. 8-9 millim.

Hab. Guatemaua, San Gerdénimo, Zapote, Senahu (Champion).

- This species appears to be nearest allied to C. picticeps, Stal, from which it differs by

the basal joint of the antenne distinctly passing the apex of the head.

PROTENOR.

Protenor, Stl, Ofv. Vet.-Ak. Férh. 1867, p. 543; En. Hem. iii. p. 88 (1873).

The unproduced and unarmed lateral angles of the pronotum separate this genus

from Cydamus ; the lateral lobes of the head are exserted and much longer than the

central, the head being subequal to or a little longer than the pronotum.

One Nearctic species has been described; a second species is here added, from

Central America. |

1. Protenor tropicalis, n. sp. (Tab. XVI. fig. 3.)

Pale ochraceous. First, second, and third joints of antenne subequal in length, with their apices somewhat .

fuscous; fourth longest, fuscous, with the base pale luteous. Head sparingly punctate and obscurely

transversely striate; lateral margins and a central longitudinal impression pale luteous. Pronotum

thickly punctate (excepting an almost levigate transverse space near anterior margin); lateral margins

and a central longitudinal slightly raised line pale luteous. Scutellum sparingly punctate. Clavus

somewhat thickly punctate. Corium with the punctures arranged in somewhat irregular longitudinal

linear series. Membrane bronzy. Underside of body concolorous; lateral margins of head, sternum, and

abdomen somewhat thickly punctate, the sternum most coarsely, and the abdomen most finely so. Legs

pale ochraceous.

Darmistus differs from Protenor by the lateral lobes of the head being very little

longer than the central, and in having the basal joint of the antenne shorter than the

second joint. But one species is known at present.

I have followed Prof. Uhler in placing this subfamily in the Coreide and after the

Alydine. Mr. Dallas also placed the genera which it comprises in about the same

position. According to present knowledge we must consider the Palearctic Region

the head quarters of the Berytine. Stal enumerates one African and three American

genera. One of the last is represented in Central America; and I have been compelled

to found a new one. i

JALYSUS.

Jalysus, Stal, Rio Hem. ii. p. 59 (1862); En. Hem. iv. p. 128 (1874).

This genus is distinct from Neides and Hoplinus, the other American genera of the

Berytine, by the impunctate corium; the apex of the clavus is produced and about

reaches the membrane ; the antenne and legs are very long, the posterior femora usually

passing the apex of the abdomen; the lateral angles of the pronotum are not prominent ;

JALYSUS.—PARAJALYSUS, 163

and the scutellum is armed with a small and suberect spine. ‘Three Neotropical and

one Nearctic species have been enumerated, a fifth is here described from Central

America.

1. Jalysus mollitus, n.sp. (Tab. XVI. fig. 4.)

Head ochraceous; eyes fuscous. Antenng ochraceous, obscurely speckled with fuscous; first joint much the

longest, second a little shorter than third; fourth short, incrassated, fuscous, with the base and apex

ochraceous ; base of the second and base and apex of the third joint also much paler in colour. Pronotum

coarsely granulate; anterior lobe ochraceous; posterior lobe fuscous, with a pale central longitudinal line.

Corium and membrane ochraceous. Legs ochraceous, distinctly speckled with fuscous; femora with the

incrassated apices paler at the extremities; apices of tibie# and tarsi fuscous. Body beneath ochraceous ;

base of abdomen somewhat testaceous; central portion of underside of head, margins of prosternum, and

disk of mesosternum fuscous ; rostrum ochraceous, with the apex somewhat pitchy.

Long. 73 millim.

Hab. Guarimata, Cerro Zunil (Champion).

This is a very variable species,—the posterior lobe of the pronotum in some specimens

being only variegated with fuscous; in others it is concolorous with the anterior lobe ;

the fuscous speckles on the second and third joints of the antenne are frequently con-

fluent or subconfluent, giving those joints the appearance of being fuscous in coloration ;

the scutellum, clavus, and membrane are also frequently suffused with fuscous. The

granulated pronotum allies it with J. tenellus, Stél; but it is most closely allied to

J. (Metacanthus) pectoralis, Dall. (the type and only example of which, in the British

Museum, is from an unknown locality and mutilated as described), from which it

appears principally to differ by the more robust thorax.

PARAJALYSUS, n. gen.

Allied to Jalysus, but differs in having the lateral angles of the pronotum strongly spinous. Base and anterior

lobe of pronotum also sometimes spinous as in type described. Corium impunctate as in Jalysus, and

apex of clavus reaching membrane as in that genus.

1. Parajalysus spinosus, n. sp. (Tab. XVI. fig. 5.)

Antenne fuscous, first joint about equal in length to second and third, fourth joint subequal in length to

second, incrassated, with the apex a little paler. Head pale ochraceous, with the eyes black. Pronotum

with the anterior lobe pale ochraceous, and armed on the disk with a long erect black spine; posterior lobe

golden yellow, coarsely punctate or subgranulose, with the lateral margins and a central levigate line pale

luteous, lateral angles armed with a long black spine directed upwards and outwards, and a long erect

spine of the same colour slightly directed backwards about centre of posterior margin. Scutellum blackish,

with a small luteous tubercle at base. Corium ochraceous, basal costal margin luteous. Membrane pale

ochraceous and subhyaline. Legs castaneous, with the incrassated apices of the femora somewhat paler ;

apices of the tibie and tarsi fuscous.

Two American species of this Palearctic genus have been enumerated. The antenne

are stout, rough, and hairy (the character relied on by Dallas) ; and Stal further differen-

tiates “marginibus lateralibus anticis thoracis totis spinoso-pectinatis.” The posterior

coxee are placed widely apart.

SCOLOPOCERUS. |

Scolopocerus, Uhler, Wheeler’s Rep. Geog. Expl. v. Zool. chap. xii. p. 832 (1875).

The author describes the genus as having the “general features of Dasycoris ;” but

he has not given differential characters. It appears to differ principally by the non-

pectinated lateral margins of the pronotum and the non-pilose but granulated antenne,

which are also described as having “the basal joint longer than the second, the third

longest, fourth very short, conical at tip, having only the base granulose.” In the

figure of the type, S. secundarius from Arizona (ibid. pl. xlii. fig. 5), these relative

antennal lengths are quite differently portrayed, which is apparently the fault of the

artist. In the Mexican species, which I have here included in the genus, the basal

joint is incrassated and slightly shorter than the second, the remaining joints as

described by Prof. Uhler. The rostrum is described as “extending nearly to the inter-

mediate coxe.”

1. Scolopocerus uhleri, n. sp. (Tab. XVI. fig. 6.)

Above brownish testaceous. Antenne pale granulate, speckled with fuscous; basal joint incrassated, slightly

shorter than the second; third longest; fourth shortest, and thickened granulate at base only. Head

sparingly subgranulate, with a central pale longitudinal line. Pronotum subgranulate, with a central

longitudinal levigate line; the disk transversely luteous, anterior and posterior portions dark fuscous, the

lateral margins slightly reflexed and sinuated, the lateral angles subprominent, slightly raised and rounded.

Scutellum subgranulose, depressed at base and towards apex, with a central longitudinal line, apex, and

SCOLOPOCERUS.—CERALEPTUS. 165

basal half of lateral margins luteous. Corium subgranulose, more or less speckled with fuscous. Membrane

pale hyaline, but appearing concolorous when folded from reflexion of upper surface of abdomen ; nervures

brown and ramose. Connexivum pale ochraceous, each segment with a cluster of brownish punctures.

Underside of body pale ochraceous; underside of head and sternum subgranulate, the basal portions of

pro-, meso-, and metasternum fuscous. Rostrum reaching base of metasternum, pitchy towards tip,

first joint a little shorter than head. Abdomen coarsely punctate. Legs pale ochraceous, spotted and

annulated with pale fuscous.

Long. 8 millim. .

Hab. Mexico, Alvarez Mountains (Dr. Palmer).

A specimen from Mexico, in the Stockholm Museum, appears to be a variety of this

species, in which the fuscous markings are almost absent, and the whole upper surface,

including the pronotum, is dull ochraceous. The sternum beneath is without the

fuscous shading; and a fuscous spot is thus very distinct on pro-, meso-, and meta-

.sternum; the abdomen beneath is also more mottled with pale fuscous.

Apparently allied to 8. secundarius, Uhler, but differs by the rostrum reaching the

base of metasternum, antenne with the joints of unequal thickness, and the colour of

scutellum &c.

The posterior coxe are contiguous or subcontiguous—a character which separates this

genus from the preceding. But one American species is at present recorded :—

Hab. Norta America, Texas 12, California 2, Arizona 2.—MeExico ”.

This species is included here on the authority of Prof. Uhler, who gives Mexico as a

habitat, and states that the species varies greatly in size and in the thickness of the

antenne, and somewhat in colour and distinctness of markings.

This subfamily, found in each of the great zoological regions, is well represented in

Tropical America, apparently and according to present knowledge more numerously

than in the eastern tropics, though the last are localities of which still comparatively

little is known of the smaller Heteroptera.

Division HARMOSTARIA.

Harmostaria, Stal, En. Hem. iii. p. 97 (1878).

This division is well distinguished by the posterior femora being incrassated and

spined beneath. It comprises a group of Neotropical and Nearctic insects, of which

but two genera have been enumerated.

HARMOSTES.

Harmostes, Burm. Handb. ii. 1, p. 8307 (1835); Dallas, List Hem. ii. p. 520 (1852); Stal, Stett.

ent. Zeit. xxiii. p. 306 (1862) ; En. Hem. i. p. 219 (1870).

The distinguishing characters given for the division Harmostaria serve roughly to

characterize this genus. |

This genus is both Neotropical and Nearctic, a greater number of the species being

found in the former region. It is largely represented in Central America.

A. Abdomen not dilated.

a. Lateral margins of the pronotum crenulated.

REPUBLIC >,

The Argentine Republic, if Prof. Berg is correct in his identification, is the most

southern habitat of the species, and would denote a very wide area of dispersal. Stal}

copies, without comment, the habitat given by Fabricius of his Syrtis serrata, “ India

orientalis (Mus. Tottianum, Mus. Havn.).” The species appears to be somewhat variable

in coloration, but is distinct from the following species by its size and by the length of

the rostrum, which only reaches the base of the abdomen.

A specimen in the Vienna Museum is here figured, which I have compared with the

typical H. perpunctatus of Dallas.

HARMOSTES. 167

3. Harmostes formosus, n.sp. (Tab. XV. fig. 15.)

Head ochraceous. Antenne with the basal joint very incrassate, dark ochraceous, and about reaching apex of

head; second and third joints subequal in length, testaceous; apex of second joint fuscous; fourth joint

short, a little longer than first, thickened and fuscous. Pronotum ochraceous, finely punctate and

obscurely wrinkled, subgranulose near anterior margin, with the lateral angles rounded and strongly

reflexed ; angular margins fuscous, lateral margins luteous and crenulated, anterior angles prominent; a

central pale longitudinal line which is raised and levigate near anterior margin ; posterior margin narrowly

pale luteous. Scutellum ochraceous, with a central longitudinal line and apical margin pale luteous.

Corium luteous, sparingly and finely punctate (clavus thickly so), with a large, elongated, fuscous spot on

disk, a row of small fuscous spots on costal margin, and a larger spot of the same colour near apical angle.

Membrane pale hyaline, with obscure fuscous spots. Underside of body pale luteous, lateral margin of

head and sternum strongly punctate; abdomen with a few scattered black punctures on anterior margin

of disk, and stigmata black; femora luteous, with their apices, tibise, tarsi, and rostrum testaceous.

Rostrum just passing posterior coxe, with the apex pitchy. Posterior femora with their apical halves

strongly spined, four spines being longest, strongest, and luteous in colour.

Long. 9 millim., lat. pronot. ang. 3 millim.

Hab. Mrxico, Cuernavaca (Bilimek, Mus. Vind. Ces.).

The strongly produced and reflexed lateral angles of the pronotum, and distinct

colour and markings, will distinguish this species from the others which form that

section of the genus in which the pronotal margins are crenulated.

Note.—In the figure the basal joints of the antenne are incorrectly delineated as not

reaching the apex of the head.

b. Lateral margins of the pronotum not crenulated.

a. Basal joint of the antenne extending considerably beyond the apex of the head.

4. Harmostes subrufus, n.sp. (Tab. XV. fig. 16.)

Head, pronotum, and scutellum luteous, sparingly but coarsely punctate. Antenne ochraceous; basal joint

incrassated and considerably passing apex of head ; second joint a little shorter than third; fourth a little

darker in colour, thickened, and about equal in length to first. Pronotum with the lateral angles rounded,

subprominent, and slightly reflexed, a central longitudinal line and posterior margin narrowly pale luteous ;

two obscure fuscous fascie near lateral margins. Scutellum with the lateral and apical margins and a central

longitudinal line pale luteous. Corium testaceous, nervures and costal margins luteous. Membrane pale

hyaline. Underside of body and legs luteous ; lateral margins of head and sternum strongly punctate.

Long. 8 millim.

Hab. Guatemata, Duefias (Champion).

5. Harmostes bicolor, n. sp. (Tab. XV. fig. 17.) co

Head testaceous, obscurely punctate. Antenne with the basal joint considerably passing the apex of head, and

‘much shorter than second joint (remainder mutilated). Pronotum testaceous, coarsely punctate ; lateral

margins, a central longitudinal line, and posterior margin (narrowly) pale luteous ; lateral angles sub-

prominent. Scutellum testaceous, with the lateral and apical margins pale luteous. Corium pale luteous ;

clavus, inner apical angles, and a series of small spots on costal margin testaceous. (In type specimen,

described, the left corium has a large testaceous basal patch on lateral margin, which is followed by a

subquadrate spot of the same colour.) Membrane pale hyaline. Underside of body pale greenish, with a

few scattered black punctures; legs ochraceous. ,

Long. 7 millim.

Hab. Mexico, Chapultepec (Bilimek, Mus. Vind. Cees.).

168 HEMIPTERA-HETEROTERA.

Besides its different colour and markings, the much less rounded and produced

lateral angles of the pronotum will separate this species from H. subrufus.

B. Basal joint of the antenne scarcely or slightly passing the apex of the head.

B. Abdomen dilated on each side.

7. Harmostes propinquus, n.sp. (Tab. XV. fig. 19.)

Head and pronotum dull ochraceous, with some scattered and irregular fuscous shadings, obscurely punctate.

Antenne ochraceous, basal joint scarcely passing apex of head, second joint shorter.than third, and about

equal to fourth, which is fuscous, with the base ochraceous. Pronotum with the anterior lateral margins

obscurely crenulated, the lateral angles subprominent and rounded, the anterior angles prominent and

acute. Scutellum ochraceous, distinctly punctate. Corium dark greyish, with the nervures and costal

margin ochraceous. Membrane pale hyaline. Connexivum dull ochraceous, with luteous spots. Under-

side of body and legs ochraceous ; sternum and abdomen sometimes with some obscure fuscous longitudinal

streaks. Underside of apices of posterior femora fuscous, and with a row of strong spines. Abdomen

dilated and projecting beyond the corium on each side.

Hab. Mexico 1.

I have with Stal been unable to identify this species; it probably represents one of the

preceding Mexican species ; but the description is too slight for any accurate decision.

AUFEIUS.

Aufeius, Stal, En. Hem. i, p. 221 (1870).

This genus at present contains but one species; and the characters relied upon by

Stal for separating it from Harmostes are, “thorace disco impresso, carina media

destituto, abdomine hemelytris latiore divergit.”

Division CORIZARIA.

Corizaria, Stal, En. Hem. iii. p. 97 (1878).

This division really comprises the old genus Corizus, several new genera having been

founded by Stal on the Oriental and Ethiopian species of that genus. It differs from the

Harmostaria by the unarmed posterior femora, and by the pronotal angles, which are

obtuse or unarmed. The anterior portions of the lateral margins of the pronotum are

either not or very obtusely sinuated. The basal joint of the antenne is short, either

not reaching or scarcely passing the apex of the head. |

CORIZUS.

Niesthrea, Spinola, Ess. Hém. p. 245 (1837).

Corizus being the only genus of the division as at present known in Central America,

little diagnosis is required beyond what applies to the Corizaria. The genus as here

treated is almost universally distributed. Its species appear to be of the most protean

character.

Stal § appears to have had some doubt as to the identity of the Philippine specimens,

as he writes “Specimina duo Philippina divergunt a speciminibus EKuropzis hemelytris

brevioribus ; an species distincta ?”

Of American specimens Prof. Uhler remarks that “ this species is quite variable in

colors,.and somewhat in proportions. Specimens from Cuba and San Domingo are

suffused with red and more distinctly pubescent than the others from Texas and

Dakota.” He further remarks? that the “species is very widely distributed «in

Eastern Colorado; at least that is the case with the variety which I described under

the name of viridicatus. It lodges in the flowers of various weeds, and seems to be

common upon the plains, foot-hills, and parks in the mountains.” “It lived singly in

the crowns of small flowers in Manitou Park, and was common upon weeds in the

Arkansas valley and near the mouth of the cafion of the Arkansas from August 4 to 19.”

Dr. Packard found it at Golden, July 8, and on Arapahoe Peak, 11,000 to 12,000 feet

above sea-level, on July 1. The specimen figured is a dark form from Guatemala.

the lateral borders of the sternum are alone black.

Prof. Uhler 4, correctly remarks Dr. Signoret, ‘ describes a Corizus which he refers

to C. lateralis, Say; but some of the characters there employed do not agree with those

given by Mr. Say.” If, however, a varietal view of the species be taken, I think these

discrepancies vanish. In the Guatemalan specimens figured, the corium agrees with

CORIZUS. 171

Dr. Signoret’s description, “Elytres transparentes, l’extréme sommet de la corie

rougeatre,” a character not mentioned by Mr. Say, who, however, describes the scutellum

“with a longitudinal impunctured whitish line,” which this same specimen exhibits,

though not referred to in the description of Dr. Signoret. In the specimens figured

the connexivum is spotted with black, as described by the last-mentioned author.

From these considerations I have felt bound to include these forms under Say’s name ;

the figures given, however, are calculated, I hope, to prevent any misunderstanding.

Stal! gives also as a habitat “Insula Taiti;”’ but as he does not reproduce the name

of this locality in his ‘ Knumeratio Hemipterorum’®, it possibly was originally given by

mistake. This is an extremely variable species, in size, colour, and markings, as

remarked by Stal®, and abundantly testified in the Central-American specimens now

before me. According to Berg it is abundant in all parts of the Argentine Republic.

The figure 24 is taken from a large and bright-coloured Guatemalan specimen; from

the same locality, however, have been received smaller, darker, and much more

obscurely-coloured examples. Fig. 25 (C. luteolus) represents the variety described by

Dr. Signoret as C. mexicanus, which was obtained in Guatemala by Mr. Champion, and

which I have followed Stal in regarding as but a varietal form.

Division SERINETHARIA.

Serinetharia, Stal, En. Hem. iii. p. 97 (1873). .

In this division the anterior portion of the lateral margins of the pronotum are

distinctly and angularly emarginated, a character which will alone separate the

_ Serinetharia from the Corizaria. Three genera are included, two of which are here

enumerated; the third, Serinetha, is found in the Ethiopian, Oriental, and Australian

Regions.

divisions.

Division LYGHARIA.

Lygearia, Stal, En. Hem. iv. p. 98 (1874). -

Stal has thus diagnosed this division:—“ Alis totis vel magnam ad partem fuscis vel

infuscatis ; margine apicali corii recto; angulo apicali exteriore tuberculorum antenni-

174 HEMIPTERA-HETEROPTERA.

ferorum obtuso vel obtusiusculo; segmento dorsali ultimo marium apice plerumque

truncato ; segmento genitali marium rarissime foveato.”

About sixteen extra-European genera are comprised in this division, four of which

are found in Central America.

| ONCOPELTUS.

Oncopeltus, Stal, Hem. Fabr. i. p. 75 (1868) ; En. Hem. iv. pp. 98 & 101 (1874).

This genus is at once recognized by the tumid scutellum with a central longitudinal

carination. The only other allied genus showing this peculiarity, but with a central

longitudinal sulcation, is from Tropical Africa. |

The majority of the species are Neotropical, seven of which have been received from

Central America ; the genus is also represented in all the other great zoological regions.

Stal divided the genus into two subgenera Oncopeltus and Erythrischius, which are

denoted but not followed here. |

This species is very protean in markings. Stal? enumerates three varieties ; but there

are other and intermediate ones. The head is either totally black or spotted with red;

the pronotum has generally a central longitudinal black line, but is sometimes without

it; and the scutellum is either luteous, red, or black. A Mexican variety is figured.

Stal has remarked that the second and third joints of the rostrum are of variable

length.

As with others of the genus, this species is also of a variable character, the principal

forms of which are as follows :—

Var. a.

The pronotum is black, with two red (sometimes luteous) spots, which extend from the anterior margin to a

little beyond the middle ; the corium and membrane are black, the first with large yellow spots at base

and apex; body beneath with a lateral series of sanguineous spots.

This variety has: been identified by Stal as the true L. varicolor, Fabr., and is the

form represented here by the fig. 21. It appears to be very scarce in Mexico. Stal®

gives no record of it from that country; and I have seen but one specimen from there,

which is contained in the Berlin Museum. It is very abundant in Costa Rica, and is

somewhat common in Guatemala; thence it extends to the most southern habitat of the

species.

Var. alternans, H.-Sch. |

This variety differs from the preceding in having the pronotal spots larger and con-

colorous with those of the corium, the lateral spots to the abdomen are larger, and the

anterior ones generally confluent.

This form appears to be almost confined to Mexico.

Var. stalii, Dist. (Tab. XVI. fig. 20.)

Disk and anterior portion of the head, pronotum, scutellum, corium, sternum, and abdomen red. Lateral

margins of the pronotum, a central longitudinal line to pronotum and scutellum, base of scutellum, a spot

on disk of corium, wide and irregular transverse fascie to sternum situated near coxe, posterior half of

disk, apex, and lateral margins of abdomen black.

This is the var. c of St&l5, but is so distinct in markings that I have considered it best

to give a separate varietal name. It appears to be quite confined to Mexico, where

the specimen figured was obtained by Herr Hoge.

A pale-coloured specimen from Mexico is here figured.

This species is distributed over a wide area. , Prof. Uhler4 states that it is common

over the greater part of the United States east of the Sierra Nevada, and extends

from Canada to Central America and Brazil. The same author § also states that in

Maryland it is common on the purple Asclepias; and Townend Glover® writes that at

the Maryland Agricultural College Mr. Peck not only found it in great abundance on

flowers of Asclepias, but also in company with caterpillars of a lepidopteron (Euchetes,

Fgle). 0. fasciatus is closely allied to the preceding species; but, apart from its

generally larger size, it may be distinguished by the much longer rostrum.

In this genus the scutellum is not tumid; the fourth joint of the rostrum is not

longer than the third, and the following characters, as pointed out by Stal, are constant

and important:—‘“Capite pone oculos, qui angulos anticos pronoti tangunt, haud

tumescente.” The characters “ Metapleuris postice recte truncatis, marginibus antico

et postico parallelis vel subparallelis, margine postico haud vel vix obliquo,” apply also

to the following genus.

St&l has divided the extra-European species of the genus into eleven subgenera, four

of which are represented in Central America, and are here denoted and used in a

sectional manner, whilst a fifth section is devoted to what Stal ultimately considered

a true generic division.

Even these divisions or sections, according to my experience, are sometimes not only

unsatisfactory, but even arbitrary, resting, as they necessarily do, almost on colour-

differences alone. |

Prof. Uhler? remarks, and apparently with excellent reason, “sufficient acquaintance

with the nature of this form may establish it to be the form of L. turcicus dependent

upon the tablelands of South-western North America.” It varies in sometimes having

the membrane spotted with white. J. turcicus, Fabr., is a species at present restricted

to North America, contingent on L. costalis, L. reclivatus, and L. kalmii not being

shown to be but southern varieties of it.

That this is but a form of L. turcicus appears to me extremely probable; and I follow

Stél and Uhler in considering it distinct with much doubt and hesitation. |

Prof. Uhler, in Hayden’s ‘Survey of Montana,’ writes:—‘‘The form described as

L. reclivatus, Say, differs from the Fabrician only in having two white dots on the

membrane. As specimens with this peculiarity occasionally hatch out of a cluster of

egos of the L. turcicus laid on the pink Asclepias in Maryland, I do not hesitate to

place it as a synonym of that species.” ‘This appears conclusive; but it was written in

1872, and the same author?® subsequently treats the two forms as distinct species,

remarking, however *, “This form is placed apart provisionally from ZL. turcicus, Fabr.,

merely because the full history of the species has not yet been elaborated.”

again follow him and Stal. The totally black clavus is one of the best distinctive

characters.

In a typical Mexican specimen forwarded to me from the Stockholm Museum, the

pronotal markings are red; in a Guatemalan specimen (here figured) the anterior

pronotal margin is luteous, whilst in two specimens from Mexico contained in the

limits of variation in the species.

The figure is from a Mexican typical specimen in the Stockholm Museum. As Stal

remarks, this species is very likely to be confounded with L. bistriangularis; but, in

addition to the subgeneric characters, it is smaller (5 to 6 millim. in length), and the

rufous colour is much more obscure. The black vitte near the lateral margins of the

abdomen beneath, as described by Stal, are very inconstant, and only exist in one

This is a very variable form, though I have felt little hesitation in identifying the

Central-American specimens as belonging to Stal’s species. All the specimens now

before me have the pale veins to the corium—a variable character mentioned by Stal.

The Panama specimen figured agrees with the description in having only the apical

Long. 7 millim.

Hab. Panama, Volcan de Chiriqui (Champion).

Allied to L. pallido-cinctus, but differs by its smaller size, the central fascia to pro-

notum, the different colour of abdomen, &c. :

Hab. Mexico 12, Orizaba (Bilimek, Mus. Vind. Ces.).

A. typical specimen in the Stockholm Museum is here figured.

Var.a. (Tab. XVII. fig. 10.)

This is a melanic form, and apparently of a constant local character in specimens

received from Panama. The four dark spots across the pronotum are present in typical

Mexican specimens, but are there much paler and more fused. The membrane is much

darker; and the veins appear concolorous.

Hab. Panama, Volcan de Chiriqui, 2000-3000 feet (Champion).

21. Lygeus interstinctus, n.sp. (Tab. XVII. fig. 8.)

Dull ochraceous, irregularly shaded with fuscous. Head ferruginous. Anterior, posterior, and lateral margins

and a central longitudinal fascia to pronotum, a central longitudinal fascia, lateral margins, and apex to

scutellum, outer, inner, and apical margins of clavus, lateral and apical margins and longitudinal veins to

corium luteous. Membrane pale fuscous, with the veins much darker, and the apical margin somewhat

broadly pale fuliginous. Sternum pale reddish fuscous; lateral margins, anterior margin of prosternum,

posterior margins of pro-, meso-, and metasternum and coxe luteous. Abdomen generally pale reddish,

sometimes dull ochraceous (if reddish, then apical segment dull ochraceous). Stigmata fuscous. Antenne

pale fuscous; legs dull ochraceous.

Long. 53 millim.

Hab. Panama, Volcan de Chiriqui, 2000-3000 feet (Champion).

This species is allied to L. pallescens, Stal, and Z. obsoletus, Stal; from the first it

differs by the pale veins to the corium, and from the second by the longitudinal pale

fascia and different markings to the pronotum.

22. Lygeus cruentatus, n.sp. (Tab. XVII. fig. 9.)

Head pale luteous, ocelli red, eyes black, apex fuscous, from which two pale and obscure fuscous arcuated

streaks extend backwards to ocelli. Pronotum ochraceous, posterior portion more or less fuscous, with

the margins and a central longitudinal vitta pale luteous, and with two large transverse red fascie situated

a little before anterior margin and on each side of central vitta. Scutellum fuscous, with a central

longitudinal luteous fascia. Corium fuscous, the lateral margins broadly and the apical margins of clavus

and corium very narrowly and indistinctly luteous. Membrane fuscous, with a broad, pale, central

longitudinal fascia. Underside of body pale luteous, two red streaks on lateral margins of prosternum, a

reddish spot on each lateral side of metasternum, and a longitudinal stigmatal fuscous line on each side of

abdomen extending about halfway from base. Legs luteous, apices of femora, tibiee, and tarsi fuscous.

Antenne fuscous.

Long. 7 millim.

Hab. Panama (coll. Dist.).

23. Lygeeus venosus, n. sp. (Tab. XVI. fig. 18.)

Lygeus poeyi, Guér., var. ?

Pale stramineous. Head above ochraceous, with the ocelli, eyes, and a short central, longitudinal, apical fascia,

widened transversely at its base, black. Pronotum with the lateral margins (broadest posteriorly), two

transverse fascize near anterior margin, a central longitudinal line on posterior portion of disk, on each

side of which is a broad fascia, in shape somewhat like a reversed letter L, pale fuscous, and with two

waved lines situated at apices of these fascie black. Scutellum with basal margin and a T-shaped fascia

near apex pale fuscous. Corium somewhat infuscated, with a lateral basal angle distinctly ochraceous, the

veins and outer claval margin pale fuscous, and lateral and apical margins narrowly stramineous.

Membrane pale fuscous, with the veins much darker. Underside of body pale stramineous; prosternum

with a pale fuscous submarginal border, a transverse pale fuscous vitta on each side of pro-, meso-, and

metasternum ; a submarginal red line on each side of abdomen, between which the segmental incisures -

are also more or less red. Antenne and rostrum fuscous, the last reaching the posterior coxe. Legs

pale stramineous beneath, and more or less pale fuscous above.

Long. 6 to 7 millim.

Hab. Mexico, Orizaba (Bilimek, Mus. Vind. Ces.); Guatumata, El Reposo (Cham-

pion); Panama, Volcan de Chiriqui, 2000-3000 feet (Champion). |

Closely allied to the Cuban species, Z. poeyi, Guér,, of which it may be a variety.

Stal, in his ‘ Hemiptera Mexicana,’ recorded that species from Mexico, but only gives

the habitat Cuba in his subsequent ‘ Enumeratio’ (pt. iv.). The markings of the pro-

notum are different from those of Guérin’s figure.

LYGAUS. 185

24. Lygeeus verecundus, n.sp. (Tab. XVIII. fig. 6.)

Pale stramineous. Head ochraceous, with the apex, a lunate spot at base, ocelli, and eyes black. Pronotum

with the lateral margins, a broad transverse fascia near anterior margin, and a central pale, narrow,

longitudinal line luteous; in the transverse fascia are two obliquely waved black lines. Scutellum

fuscous, with a large cruciform luteous fascia. Corium with the lateral margins luteous, the two main

longitudinal veins and an apical claval streak dark chocolate-brown. Membrane very pale dull

ochraceous ; basal margins narrowly chocolate-brown, and the basal veins somewhat darker. Underside of

body pale ochraceous; sternum with the posterior margins of each segment somewhat paler, and with two

transverse black lines near anterior cox, which are united near lateral margin; a transverse black line

near lateral margins of meso- and metasternum, and a black spot near posterior coxe. Abdomen with a

series of transverse stigmatal black lines, and with the apical segment paler. Antenne and rostrum pale

fuscous ; legs dark ochraceous, with the tarsi pitchy.

Long. 9 millim.

Hab. Gvuatemata, near the city (Champion).

This species is allied to L. modestus, Stal, from which it differs by the dark veins to

corium, its smaller size, &c. ;

~—- Head totally or posteriorly black, without a pale basal spot. MELANOCORYPHUS, Stal.

Melanocoryphus, Stal, En. Hem. iv. pp. 99 & 111. -

Stal originally regarded this division as a subgenus under the above name, but after-

wards treated it as of generic rank. The colour of the head, however, appears to be

the only character relied upon by that author to separate it from Lygeus, which, in my

view, does not render it less congeneric than some of the previously enumerated

divisions. Moreover, in one species subsequently referred to here (p. 187), M. witti.

scutis, Stal, the head is sometimes luteous, with but two black basal spots.

This group is almost confined to tropical and subtropical America, but is also

represented in South Africa.

very pale reddish central longitudinal fascia, which commences near base, and is continued along the

claval apical margins. Corium with the lateral and apical margins pale reddish. Membrane black.

Underside of the body pale reddish; head, antenne, rostrum, a rounded spot on each side of prosternum

The specimen figured is in the Vienna Museum, which differs slightly from

Mr. Dallas’s description in having the anterior margin and also the lateral angles

red. These characters apply also to all the specimens which I have examined, and

are in agreement with the description given by Stal? of examples in the Stockholm

Museum.

This is a variable species. The Guatemalan specimens examined have the head

luteous, with two black spots, thus bringing into doubt the generic value of the

colour of the head relied upon by Stal. That this is not a southern characteristic

is evidenced by a Nicaraguan specimen which agrees with typical Mexican forms, of

which I have examined the type in the collection of Dr. Signoret, and also a typical

specimen identified by Stal in the Stockholm Museum. In the Guatemalan specimens

now before me the lateral black borders to the sternum and abdomen are very

indistinct and almost obsolete.

34. Lygeus consanguinitas, n. sp. (Tab. XVIII. fig. 12.)

Head black; pronotum luteous, with two broad and somewhat fused transverse black faseis near anterior

margin, from which proceed posteriorly two other gradually widening fascie of the same colour, which

terminate near posterior margin, and are there outwardly angulated. Scutellum fuscous; a central line

commencing halfway from base, apex, and lateral margins luteous. Corium fuscous; lateral and apical

Hab. Mexico, Orizaba (Bilimek, Mus. Vind. Cas.).

I place this peculiarly and distinctly marked species at the end of the Central-

American species of the genus Lygeus.

ACROLEUCUS.

Acroleucus, Stal, En. Hem. iv. pp. 99 & 114 (1874).

This genus differs primarily from Lyg@us in having the membrane black or fuscous,

with a broad pale apical margin, or a triangular apical spot of the same colour. Other

characters relied upon by St&l are—‘ Femoribus inermibus” and ‘“Capite interdum

pone oculos tumescente.”

Acroleucus appears to be confined to the Neotropical Region, but is more numerously

represented south of Central America.

1. Acroleucus subniger, n. sp. (Tab. XVIII. fig. 10.)

Head, pronotum, scutellum, and body beneath red. Apex of central lobe to head, eyes, a transverse fascia at

This species is very closely allied to the last, but is usually smaller, and, as Stal

remarks, ‘““cum eodem hemelytrorum margine costali recto insignis.” The posterior

margin of the pronotum is not luteous as in the preceding species.

The type, in the collection of Dr. Signoret, is here figured.

4. Acroleucus vicinalis, n. sp. (Tab. XVIII. fig. 8.)

Black. Pronotum with the anterior third and a central longitudinal fascia dull red. Scutellum with a pale

luteous central fascia, which commences at a short distance from base, and is continued along apical

claval margins. Corium with the lateral and apical margins pale luteous, the former distinctly widened at

base. Membrane black, apical margin widely pale hyaline. Underside of head black ; prosternum reddish ;

meso- and metasternum black, with the posterior margins and acetabula dull ochraceous; abdomen pale

ochraceous, a broad submarginal fascia and apical segment black. Antennz, rostrum, and legs fuscous ;

trochanters much paler.

Allied in general appearance to Lygeus vittiscutis, Stal, but smaller, with the pronotum

more quadrate, and the colour-markings different.

Division ORSILLARIA.

Orsillaria, Stal, En. Hem. iv. pp. 98 & 119 (1874).

Nysiina, Uhler, Bull. U.S. Geol. & Geog. Surv. ii. p. 304 (1875).

Nysiine, Uhler, Bull. U.S. Geol. & Geog. Surv. iii. p. 409 (1877).

This division was founded by Stal on the following characters :—‘Alis decoloribus

190 HEMIPTERA-HETEROPTERA.

vel sordide subalbido-hyalinis; margine apicali corii prope apicem clavi sinuato;

angulo apicali tuberculorum antenniferorum prominulo, acuto vel acutiusculo ; seg-

mento dorsali ultimo marium mihi cognitorum apice plus minus rotundato, segmento

genitali marium foveato.”

Three extra-European genera at present exist—one, according to present knowledge,

confined to the Nearctic Region, one principally Palearctic, but also recorded from

North America, and the other probably cosmopolitan, and represented in this fauna.

NYSIUS.

Nysius, Dallas, List Hem. ii. pp. 581 & 551 (1852); Stal, En. Hem. iv. p. 119 (1874).

Nysius, subg. Macroparius, Nysius et Ortholomus, Stal, Ofv. Vet.-Ak. Férh. 29. 7, p. 43 (1872).

The position of the posterior acetabula, “leviter distantibus,” and the unarmed

anterior femora are the strongest differential characters of this genus, the distribution

of which, as we have previously remarked, is probably cosmopolitan.

One species is at present here alone enumerated. This is evidently an inadequate

return; for doubtless many more exist. A Mexican one in the collection of the Berlin

Museum has passed through my hands, so closely allied to MW. simulans, Stal, from

Buenos Ayres, that I did not feel justified, without the examination of a series of

specimens, either in identifying it as that species or describing it as new.

Hab. Mexico? (Mus. Berol.); Honpuras !.—Brazit, Rio Janeiro! ; Tarr} 3,

There seems to be some confusion as to the habitat of this species. Although “ Insula

Taiti” is twice given by Stal (see supra), he, however, records a single specimen from

Honduras sent by Dom Hjalmarson!, and also enumerates both male and female in

his ‘Hemiptera Mexicana’*. A Mexican specimen in the Berlin Museum seems to

agree well with Stal’s description.

Cymina, Stal, En. Hem. iv. p. 123 (1874).

Cymine, Uhler, Bull. U.S. Geol. & Geog. Surv. iii. p. 409 (1877).

This subfamily of the Lygzide is recognized by the hemelytra being wider than the

abdomen. It has been divided into two divisions.

NINUS. | | 191

Division ISCHNORHYNCHARIA.

Ischnorhyncharia, Stal, En. Hem. iv. p. 123 (1877).

This division can be at once separated from the division Cymaria by the single

character “ commissura scutello haud longiore.”

NINUS..

Ninus, Stal, Freg. Eug. Resa, Ins. Hem. p. 252 (1859) ; En. Hem. iv. p. 170 (1874).

This very peculiar genus, which was founded by Stal for a single species from the

island Guam, was originally placed by him near his Cymus franciscanus, which is a

synonym of Ischnorhynchus resede, Panz. He afterwards, however, in the fourth part

of his ‘Enumeratio Hemipterorum’ placed it only in “genera et species Lygeidarum

incerti loci systematici.” I cannot, however, consider that he erred in placing it as he

originally did, and have been compelled myself to follow that course.

It is at once recognized by the elongated body, exserted eyes, and the deep emargi-

nation of the costal margin of corium near base. The antenne have the basal joint

not or scarcely passing apex of head; and the second and fourth joints are subequal in

length.

1. Ninus notabilis, n. sp. (Tab. XIX. fig. 4.)

Head piceous, more or less clothed with ochraceous pubescence; eyes dark castaneous; antenne ochraceous

and pilose, first joint shortest and globosely incrassated, second and fourth subequal, a little longer than

third, fourth thickened and pale castaneous. Pronotum castaneous, sparingly clothed with ochraceous

pubescence, and with two transverse black fascie near anterior margin. Scutellum castaneous, somewhat

coarsely punctate and wrinkled at base, where it is also clothed with ochraceous pubescence, and with a

raised, central, longitudinal ochraceous line near apex. Clavus somewhat paler, the apical margins

ochraceous, and apex fuscous. Corium pale ochraceous hyaline, the margins ochraceous, and apical

angles fuscous. Membrane pale hyaline. Underside of head and sternum castaneous, coarsely punctate,

the last with four lateral black spots—situated two on prosternum, one on mesosternum, and one on

metasternum. Abdomen beneath very pale ochraceous; legs ochraceous, femora castaneous, and apices

of the tarsi pitchy.

Long. 34 millim.

Hab. Guatemata, Panajachel (Champion).

The eyes are strongly exserted and slightly directed backwards. The pronotum is

gradually widened posteriorly, and somewhat gibbous near the lateral angles, which are

broadly rounded. The posterior margin of the pronotum is subequal in width to that

of the head between outer margins of eyes.

This species is allied to WV. insignis, Stal, from which it differs by the absence of the

costal spot to corium, the unicolorous membrane, pale-coloured tibie, &c.

192 HEMIPTERA-HETEROPTERA.

NEONINUS, n. gen.

Closely allied to Ninus, but differs by having the first joint of the antenne distinctly

passing the apex of the head, and the second joint much longer than the fourth, which

is subequal in length to the third; the fourth joint is also strongly incrassated. ‘The

head is more elongate, the eyes less prominently exserted, and the pronotum more

elongate and narrowed anteriorly than in Stal’s genus.

1. Neoninus illustris, n.sp. (Tab. XIX. fig. 5.)

Head, pronotum, scutellum, clavus, and base of corium dark fuscous, thickly clothed with pale greyish

pubescence., Head coarsely punctate; ocelli prominent and black; antenne with the first and fourth

joints dark castaneous, the second and third pale luteous, first shortest and globosely incrassated, second

longest and longer than fourth, apical joint much thickened. Pronotum coarsely punctate, with a central

pale longitudinal line, less pubescent and more fuscous posteriorly, and with two pale, transverse and

waved fascie, situated a little before anterior margin. Scutellum coarsely punctate, with the basal angles

and a central longitudinal line pale greyish. Clavus with the usual series of punctures, and with the

apex broadly dark fuscous. Corium pale luteous hyaline, with the basal angle greyish pubescent, beyond

which it is slightly dark fuscous, apical angles fuscous. Membrane pale hyaline. Abdomen above

greenish. Head beneath and sternum fuscous, clothed with greyish pubescence and coarsely punctate.

Rostrum ochraceous, the base fuscous (apex mutilated). Femora castaneous; tibise and tarsi pale

ochraceous, the last with the apical joint pitchy.

Long. 4 millim.

Hab. Guatemata, Torola, Chiacam (Champion).

An apparently rubbed specimen, sent by Mr. Champion from Chiacam, has lost

the greyish pubescence, thus exhibiting the head, pronotum, scutellum, and clavus

dark fuscous. 7

ISCHNORHYNCHUS.

Cymus, subg. Lyctus, Flor, Rh. Livl. i. pp. 287 & 294 (1860).

Ischnorhynchus, Fieb. Kur. Hem. pp. 51 & 199 (1861) ; Stal, Ofv. Vet.-Ak. Férh. 29. 7, p. 44

(1872) ; En. Hem. iv. p. 123 (1874).

This genus may be known by the apex of the corium passing the apex of the

abdomen, a character which will separate it from the only other American genus at

present described. The body is oval; and the apical margin of the corium and claval

suture are of nearly equal length.

This genus is represented in the Palearctic, Nearctic, and Neotropical Regions.

There are at present but few described species; but as these are small and obscure,

and therefore at present little known from the labours of the average collector, [schno-

rhynchus may probably have a much wider range and possess many more species.

Dr. Puton has proposed the substitution of the name Kleidocerus, Westw., for this

genus; but Mr. Douglas Has argued (Ent. Mo. Mag. xv. p. 235) that Kleidocerus

“ being merely a name, it cannot supersede Ischnorhynchus, which is a genus duly

defined by Fieber.” ,

I can detect no real differences between the Panama and Mexican specimens of this

species which I have examined, nor between these and North-American or European

representatives. According to Prof. Uhler%, it is quite common both in the eastern

and western sections of the United States, and is found as far north as Lake Winnipeg.

Stal also gives habitats ranging from California to Siberia; and even now that we have

traced it to the mountains of Panama and Guatemala it may perhaps be accepted as a

boreal species, whose presence in these Central-American mountains refers to southern

migration at that Glacial period of which Belt found, and has described, so many

evidences in this region. Mr. Dallas? had previously detected the specific unity of the

European and North-American forms.

NINYAS, n. gen.

Eyes very large, exserted, and directed backwards. Antenne with the basal joint passing the apex of the

head, the second and fourth joints subequal in length, apical joint incrassated. Pronotum with the

posterior margin slightly convex ; lateral margins simple, and with a transverse levigate callosity near

anterior margin ; posterior margin subequal in width to that of head, including outer margin of eyes,

and wider than anterior margin. Corium with its apex not reaching apex of abdomen, with its lateral

margins strongly emarginate a short distance from base, and then much more considerably widened and

ampliated to apex. Membrane long, and considerably passing the apex of abdomen.

This genus should have been placed next to Minus and Neoninus, with both of which

it agrees in not having the apex of the corium extending to the abdominal apex ; but

from both of these genera it differs by the relative lengths of the antennal joints, by

the very large and strongly exserted eyes, and by the transverse callosity near anterior

margin of the pronotum, &c.

anterior transverse levigate callosities margined on each side by a row of closely arranged, small, dark

punctures ; remaining surface coarsely punctate, with two large fuscous spots at base, near lateral angles,

and the lateral margins very narrowly fuscous. Scutellum black, with the apex luteous, coarsely punctate,

with two yellow levigate spots at base, and a broad central levigate fascia, which about reaches apex,

but does not extend to base. Clavus luteous, with two rows of coarse punctures along its outer margin,

and a single row of the same on apical portion only of its inner margin. Corium pale luteous and sub-

In this genus the femora are either wholly unarmed, or (more rarely) the anterior

femora are obsoletely spinous; the apical margin of tbe corium is straight. These

characters separate Ischnodemus from the two other American genera.

Two species are here enumerated as found in Central America. Walker (Cat. Het. v.

p. 127) described a Mexican species in this genus under the name of Jschnodemus

longus. Neither type nor example of that species now exists in the British Museum ;

and as Walker’s species can only be recognized in systematic entomology where types

can be examined, as the genera in which his species are placed are so frequently erro-

neous, this species of Ischnodemus(?) must be considered as non-existent.

This species is very closely allied to L. falicus, Say, from which it differs by the

colour of the rostrum and antenne. The basal ochraceous portion of the pronotum is

also smaller than in Say’s species, judging from that author’s description and Dr.

Signoret’s figure of the species. As Prof. Uhler has not (so far as I am cognizant)

alluded to any variation in J. falicus, I have been compelled to describe this insect as

@ new species. .

The apical margin of the corium in Blissus is obtusely angulated and sinuated near

the apex of the clavus, a character which alone will differentiate it from the preceding

genus. Blissus has a wide habitat, being recorded from South Africa, Abyssinia, and

the Oriental and Palearctic Regions.

This is the well-known ‘‘Chinch Bug,” one of the most noxious and injurious insects

to the agriculturists of North America. According to Riley the injury is caused by

the insect sucking, by the aid of its rostrum, the grasses and cereals, “ thereby causing

them to shrink, wilt, and wither—and not by biting their substance, as many persons

suppose.” ‘The multiplication of the insect in North America appears to have been

BLISSUS.—GEOCORIS. 197

conterminous with the increase of grain-cultivation in that country ; and the injury it

occasioned to the “small grains” in the North-western States in 1871 amounted to

upwards of thirty million dollars; whilst in 1874’ the damage was computed at twice

thatsum. It has been found by Riley to be two-brooded in some of the United States ;

and its eggs are deposited “ occasionally above ground on the blades of grain—but far

more often, and normally, underground, upon the roots of the plants infested.” The

same author states that though abundantly able to fly, the Chinch Bug does not take

to wing readily; and in their immature stage, before their wings are developed, they

migrate from field to field on foot, “ often in solid columns inches deep.” It multiplies

most in hot and dry seasons, moisture proving unfavourable to its existence. .

With the exception of Cuba, given by Stal, I have met with no record of a more

southern habitat for this species than the United States. It is therefore interesting, in

a biological if not in an agricultural sense, to find it distributed throughout Central

America.

In the Geocorine the membrane possesses no basal areolet. No thorough knowledge

of the distribution of this subfamily is at present obtainable, as its members are small

in size and have hitherto, in many large regions, been scarcely at all collected. All

conclusions on the general distribution of the Geocorine must therefore at present be

quite empirical. The extra-European species have been separated by Stal into three

genera; and this may probably apply to the whole subfamily as at present known ; for

though Stal has proposed some new genera for the European species, these have been

treated by Dr. Puton as only subgenera of Geocoris, a widely distributed genus, and

the only one yet received from Central America.

least found in all the principal zoological regions.

The markings of the pronotum in this species are of an extremely variable character,

which I have been afforded an opportunity of examining, agrees more closely with my

fig. 16, which, with fig. 15, may be taken as representative of the extreme varietal

forms. The course of this variation appears to extend from specimens in which the

disk of the pronotum is almost wholly black, with a small luteous fascia both on

anterior and posterior margins, through others in which these paler fasciee are increased

anteriorly and posteriorly till they meet and thus form one continuous and dividing

longitudinal fascia.

Prof. Uhler (Bull. U.S. Geol. & Geogr. Surv. ii. p. 306) placed this species as a

synonym of G. bullata, Say. Subsequently, however (ibid. iii. p. 409), he has treated

Say’s species as distinct, and, remarking upon its very varietal character, observes that

‘‘ full series of these varieties are needed to settle the synonymy of this species and its’

allied forms. Some links, pointing to a connection with G. pallens, borealis, and

discopterus, have already been procured; and doubtless still others will occur when

closer attention is given to collecting them.” Prof. Uhler is the recognized authority

on North-American Rhynchota; and I have therefore gladly followed him here. All

the Central-American specimens which we have received through Mr. Champion are

constant in character and of the form described by Mr. Dallas, of which I have examined

202 HEMIPTERA-HETEROPTERA.,

4. Ligyrocoris oblitus, n. sp. (Tab. XIX. fig. 9.)

Head pitchy, thickly covered with greyish pubescence; eyes and antenne pale brownish, the last with the

basal two thirds of the first joint and the whole of the fourth joint pitchy. Pronotum pale brownish, with

six longitudinal dark-brown fascie, two central and two near lateral margin. Scutellum pitchy, with

three raised and paler longitudinal strie, one central and two lateral. Corium pale stramineous, with a

small pitchy spot on disk near base, and with a broad pale brownish streak, commencing about centre of

claval margin, and extending along the length of apical margin, where it is broadest; near apical angle

this more or less encloses a pale stramineous spot. Membrane very pale and unicolorous whitish hyaline.

Body beneath pitchy; sternum more or less covered with greyish pubescence. Anterior femora pitchy,

with their apices narrowly ochraceous; intermediate and posterior tibiee ochraceous, with their apical

halves pitchy ; tibise ochraceous.

Long. 43-5 millim.

Hab. Guatemata, San Gerdnimo (Champion).

We have received two specimens of this species from Mr. Champion, which vary in

size as stated above; they also vary in the extent of the broad brownish border to the

apical margin of the corium, which in the larger specimen becomes obsolete towards

the apical angle. The pale white membrane and distinct markings of the pronotum

and corium render this an easily recognized species.

The specimen figured is the typical P. piligera, Stal, described from and contained

in the collection of Dr. Signoret. In his description of this species Stal gives the apex

of the first joint of the antenne as “ nigro-fuscis ;” and in his ‘ Enumeratio ’? states as a

varietal character “articulo primo antennarum nigro.’ All the Central-American

specimens which I have examined have the basal joint of the antennz black.

7. Ligyrocoris infumatus, n. sp. (Tab. XIX. fig. 8.)

Head, anterior lobe of pronotum, and scutellum black ; posterior lobe of pronotum and corium ferruginous,

the first with four longitudinal fuscous fasciz, two central and two lateral; the corium with a spot near

base ; a broad, irregular transverse fascia near apex, and apical angle fuscous. Membrane opaque, fuscous,

with the veins pale at base. Antenne ochraceous, apex of third joint, and more than apical half of

fourth fuscous. Body beneath fuscous; legs ochraceous; anterior femora, excepting apex, apices of

intermediate and posterior femora, apices of tibie, and last joint of tarsi fuscous. The body above is

sparingly pilose, the posterior lobe of the pronotum is sparingly but coarsely punctate; the corium is

punctured in longitudinal series; and the anterior femora are armed beneath with a few small spines near

apex. -

Long. 6 millim.

Hab. GUATEMALA, Quiche Mountains (Champion).

In one specimen examined the whole of the apical joints of the antenne are fuscous.

This observation has prevented me from following Stal in using the colour of the

apical joint of the antenne as a sectional character by which to divide the species of

the genus.

In this genus the head is longer than the pronotum, and is placed at the end of a

long, exserted, cylindrical neck. ‘The basal joint of the antenne moderately passes the

apex of the head.

Myodocha is found both in the Nearctic and Neotropical Regions.

A typical specimen in the Stockholm Museum is here figured.

2. Myodocha intermedia, n. sp.

Closely allied to WM. longicollis and M. giraffa. It differs from M. longicollis by the somewhat shorter neck

(in one specimen, however, this is equal in size), femora distinctly annulated on fuseous portion near

apex, and anterior femora armed beneath with a double series of short, stout spines, the longest of

which is situated on the annulated portion near apex. From MV. giraffa it differs by the much longer

neck, larger size, and more numerously spined anterior femora.

Long. 11-12 millim.

Hab. Mexico, Orizaba (Mus. Vind. Cos.) ; GUATEMALA, Pantaleon, Aceituno, Senahu

I have been compelled to give this form a distinctive name, though I should not be

surprised if it were ultimately proved to be but a variety of WU. gwaffa: I have great

doubts about the length of the neck being a constant specific character in this genus ;

it is certainly variable in the specimens of WZ. intermedia now before me.

5. Myodocha inermibus. (Tab. XVIII. fig. 23.)

Head and anterior lobe of pronotum black, the last with the lateral margins and a central longitudinal line

pale obscure greyish ; posterior lobe of pronotum and corium pale castaneous. Oorium with a small

spot near apex of clavus, apical angle and a transverse fascia near apex ochraceous. Scutellum castaneous,

black at base. Membrane pale fuscous, with the basal half black, and with a curved ochraceous basal

fascia. Legs ochraceous, apical halves of femora pale castaneous. Antenne with the basal and apical

joints fuscous, the last with the apex ochraceous ; second and third joints ochraceous, third with the apical

half fuscous. Head beneath and sternum black ; body castaneous. The posterior lobe of the pronotum,

base and lateral margin of the scutellum, and clavus coarsely punctate; the corium is longitudinally and

submarginally punctured ; and the anterior femora are unarmed.

Long. 9 millim.

Hab. Panama, Volcan de Chiriqui, 2500-4000 feet (Champion).

The unarmed femora render this species very distinct. One specimen only has been

sent home by Mr. Champion.

Hereus differs from Myodocha in not having the long cylindrical neck ; and the post-

ocular and anteocular portions of the head are subequal in length. Its distribution,

like that of the preceding genus, is apparently confined to the Nearctic and Neotropical

Regions. |

1. Hergus eximius, n. sp. (Tab. XVIII. fig. 21.)

Head, anterior lobe of pronotum, and scutellum black; posterior lobe of pronotum and legs chocolate-brown,

disk in a subcostal streak, chocolate-brown, with a large pale transverse whitish spot near apex, and the

extreme apical angle a little paler. Membrane dark castaneous, veins somewhat paler towards base, and

with an elongate ochraceous spot at apex. Antenne with the first three joints ochraceous, third with the

apex fuscous, fourth pale stramineous with the apex.fuscous. Rostrum brown; apical joint ferruginous,

with the tip fuscous. Intermediate and posterior femora with their basal third stramineous ; tarsi ochra-

ceous. Underside of body very dark chocolate-brown.

Long. 9-10 millim.

Hab. GuatEeMa.a, near the city, San Gerénimo, Capetillo, Las Mercedes (Champion).

Apparently allied to H. cincticornis, Stal, from which it differs by the absence of

pale markings to posterior lobe of pronotum, different colour of the legs and antenna,

somewhat larger size, &c.

2. Hereeus percultus, n. sp. (Tab. XIX. fig. 10.)

Head, pronotum, and scutellum black; the base of the posterior lobe of pronotum marked with four obscure

ochraceous spots, two smallest and central, and one near each lateral angle much larger. Corium pale

ochraceous, with a transverse fascia on disk which is widest anteriorly, and a large subquadrate spot at

apical angle black. Membrane obscure hyaline, the veins pale ochraceous. Antenne with the basal

joint (excluding apex) and the apical joint fuscous; apex of first, and the second and third joints

ochraceous. Anterior femora black, with their apices ochraceous; anterior tibiae and intermediate and

posterior legs pale ochraceous ; apices of anterior tibis and an annulation near apices of intermediate and

posterior femora fuscous. Body beneath black; rostrum with the basal joint brownish, second joint

pale ochraceous (remainder mutilated). Anterior femora strongly spinous beneath; posterior lobe of

pronotum very coarsely punctate and very slightly paler in hue than the anterior lobe. Clavus with

three longitudinal series of punctures, two of which become somewhat fused towards apex. Corium

sparsely punctate, the punctures in linear series.

In this genus the head is not or but little exserted, the postocular portion of the

head being shorter than the anteocular. The body is elongate, with the corium

sparsely punctate; and the clavus is longitudinally punctate in linear series, but these

series become more or less fused and irregular. The posterior margin of the pronotum

is either truncate or slightly concave.

This genus is probably almost cosmopolitan.

Head, anterior lobe of pronotum, and scutellum black, the apex of the last ochraceous ; posterior lobe of pronotum

dull obscure castaneous, with a central longitudinal raised carinate line, and with the lateral angles ferru-

ginous. Corium pale ochraceous, clavus more or less fuscous near apex, a pale fuscous streak near centre

of outer claval margin, a broad irregular black fascia on disk, widest interiorly, and a smaller one of the

same colour situated just before apical angle, and extending along apical margin. In the posterior inner

angle of the discal fascia is a rounded ochraceous spot. Membrane black, the apex broadly pale ochraceous,

and narrowly ochraceous at apical angles of corium. Antenne with the two basal joints ochraceous, third

ochraceous with the apex fuscous, fourth fuscous with the base ochraceous. Legs ochraceous, the anterior

femora, and apices of intermediate and posterior femora, brownish. Head beneath and sternum dark

fuscous ; acetabula and posterior margin of metasternum ochraceous; abdomen dull castaneous. The third

joint of the antenne is distinctly incrassated at apex, where it is as thick as the apical joint ; the anterior

_ femora are much thickened, and armed with a double series of somewhat widely separated spines.

Long. 53-6 millim.

Hab. GuatEeMaua, Chiacam (Champion).

This species is allied to P. crassicornis, Stal, from which it differs by the smaller size,

apical joint of the antennee not wholly fuscous, and by the small pale spot in the discal

fascia, which is not mentioned by Stal in his description. The two species are allied

by the peculiarly thickened apex of the third joint of the antenne.

angles pitchy. Membrane pale ochraceous, with the apical half much suffused with brown, and with a few

indistinct central pitchy spots. Abdomen beneath reddish with the apex black; sternum black; antenns

and legs ochraceous ; the tarsi somewhat pitchy. The anterior lobe of the pronotum is about half as broad

again as the posterior lobe, both being clothed with a few long hairs on each side, and the posterior having

a few scattered punctures; the scutellum has also a few scattered punctures near apex. Clavus punctured

The lateral margins of the anterior lobe of the pronotum and the anterior femora are

strongly setose; the lateral angles of the posterior pronotal lobe are subprominent,

subnodose, and rounded ; the anterior femora are armed beneath with strong spines, of

which about five are very prominent; the anterior tibie are inwardly armed with a

very strong spine a little before the middle.

This genus differs from Pamera in having the body less elongate, the corium more

strongly punctate, and the clavus longitudinally punctate in three linear series; the

scutellum has a central, longitudinal, carinate line.

The genus, as thus restricted by Stal, appears to be quite confined to the Nearctic

subapical and narrower; membrane pale brownish, with a small luteous spot near angle of corium.

Anterior femora castaneous, with their apices luteous ; intermediate and posterior femora luteous, with a

large castaneous annulation near apex; tibie luteous, annulated with castaneous at base, and with

_ the apex also castaneous ; tarsi luteous, with their apices more or less castaneous. The posterior lobe

of the pronotum and remaining upper surface is more sparingly pilose than the head and anterior

pronotal lobe, the last of which is wider but considerably narrower than the posterior lobe, which is

coarsely punctate. The anterior femora are armed beneath with a few very distinct spines near apex.

Hab. GuateMaLa, Quiche Mountains (Champion).

This species varies much in size, and is apparently most closely allied to P. twmens,

Stal, from which it differs by the different colour of the antenne, colour and markings

of corium, &c. The colour of the antenne is also variable, in some species being

altogether piceous. The species is also inconstant in amount of melanism.

CHOLULA, n. gen..

Body elongate ; pronotum large and subglobose, with the transverse constriction profound, the anterior lobe a

little shorter and narrower than posterior lobe; basal margin concave at base of scutellum ; the lateral

angles rounded, slightly ampliated and posteriorly produced. Head but little exserted, as in the two pre-

_ ceding genera. Scutellum with a central carinate line as in Ploctomera, but differing from that genus by

the less punctate corium, and in having the clavus more or less punctured, as in Pamera.

a large fuscous subapical spot. Membrane pale fuscous. Connexivum luteous, with subquadrate pale

castaneous spots. Legs pale ochraceous ; anterior femora and apices of intermediate and posterior femora

darker ochraceous. Body beneath with the sternum dull dark castaneous; the posterior margins of the

pro-, meso-, and metasternum dull ochraceous. Abdomen pale castaneous, with the lateral margin

spotted with luteous. Anterior femora armed beneath with a few spines.

Long. 44 millim.

Hab. Guatemana, Torola (Champion).

Only one specimen of this species has been received from Mr. Champion.

2. Cholula bicolor, n. sp. (Tab. XIX. fig. 18.)

Head, pronotum, and scutellum black and obscurely punctate. Antenne pale ochraceous, the apical joint

somewhat darker ; basal joint shortest, second longest, and third and fourth subequal in length. Margins

of pronotal angles pale ochraceous. Corium pale ochraceous, with scattered and darker punctures ; costal

margins and a space near inner apical angle impunctate. Membrane pale hyaline, but reflecting the dark

colour of the upperside of abdomen. Legs pale ochraceous. Body beneath piceous; posterior angles of

pro- and metasternum and acetabula ochraceous. Anterior femora armed beneath with a few strong

spines. ,

Long. 4 millim.

Hab. Guatemata, Zapote (Champion).

We have received two specimens of this species from Mr. Champion, both of which

are constant in markings.

PEPHYSENA, n. gen.

Anterior lobe of the pronotum globose, and twice as long as the posterior. Head globose, strongly exserted,

and placed at the end of an elongated cylindrical neck, the length of which is variable; basal joint of

antennz reaching or passing the apex of the head. Anterior femora strongly incrassated and spined

beneath ; anterior tibise curved and unarmed..

This genus differs from all the preceding genera here enumerated (with the exception

of Pseudopamera) by the greater length of the anterior lobe of the pronotum. It is most

closely allied to Erlacda, Sign., a genus, according to present knowledge, confined to.

Chili, from which it differs by the unarmed anterior tibie, and the anterior lobe of

the pronotum being only twice, not three times, as long as the posterior.

1. Pephysena levis, n. sp. (Tab. XVIII. figg. 24 & 25.)

Head and anterior lobe of pronotum black, posterior lobe of pronotum chocolate-brown. Antenne with the

first three joints ochraceous, extreme apices of second and third and the apical joint fuscous ; second joint

longest, third and fourth a little shorter than second and subequal in length. Scutellum black, with the

apex ochraceous. Corium ochraceous, with numerous and confluent castaneous markings, which more or

less regularly compose a claval and a subclaval fascia and two transverse fasciee, one near apex of

, a7

212 -YEMIPTERA-HETEROPTERA.

scutellum, and the other near base of membrane (the first of these transverse fascie, however, is in many

specimens practically obsolete), and a broad black apical margin. Membrane pale fuscous hyaline, the

basal half fuscous, with the basal margins pale, the apical half more or less streaked with fuscous. Femora

pale castaneous, with their bases more or less ochraceous ; tibis dull deep ochraceous; tarsi ochraceous,

with their apices fuscous. Body beneath with the head and sternum piceous, the abdomen dull deep

castaneous; intermediate and posterior coxe, dull ochraceous.

Long. 6-7 millim.

Hab. Guatemata, Tamahu, Senahu (Champion).

The variability of this species is of the most extraordinary character, as it affects such

a good structural character as the length of the neck. This is most inconstant in the

specimens now before me, extreme forms of which are here figured, but between them

all intermediate varieties exist. When we reflect that this character has been greatly

used in differentiating species of Myodocha (doubts as to the value of which were

expressed, anté, p. 203), the opinion becomes stronger that not infrequently in the

Heteroptera a multiplicity of specimens is in an inverse ratio to a plethora of species.

The anterior lobe of the pronotum is very globose, and as broad as long.

2. Pephysena insignis, n. sp. (Tab. XX. fig. 9.)

Head and anterior lobe of pronotum shiny black ; antennz pale castaneous, base of the first joint white, second

and fourth joints longest and subequal in length. Posterior lobe of pronotum pale castaneous, coarsely

punctate, clothed with pale creamy pubescence in front. Scutellum black. Clavus black, the outer basal

margin creamy. Corium ochraceous, with a broad transverse central fascia and a subtriangular apical

fascia black; between these black fascie the colour is creamy and somewhat iridescent; the extreme

apical margin is ochraceous, and the costal margin, as far as the central black fascia, pale stramineous.

Membrane fuscous, the basal margin faintly ochraceous, and with a central longitudinal pale greenish

line on apical half. Body beneath black, the abdomen castaneous ; posterior angles of pro- and meta-

sternum castaneous, lateral margins of abdomen ochraceous; coxee and legs ochraceous, the posterior legs

darkest, the bases of the fore and intermediate femora and the intermediate tibie being very pale.

Long. 7 millim.

Hab. Panama, Bugaba (Champion).

The anterior lobe of the pronotum is much longer than broad, a character which, in

addition to the colour and markings, will at once serve to distinguish this species from

P. levis. The corium is sparingly punctate, and the anterior femora strongly spinous

beneath.

wish to follow that author as I have hitherto done with great advantage to my know-

NEOCATTARUS. 213

ledge of the Order, I have here failed to interpret his meaning sufficiently to prevent

confusion.

As defined by Stal, the “ Rhyparochromaria,” in his restricted sense, is separable from

the preceding division here enumerated by the absence of the distinct collar at the

anterior margin of the pronotum, of which the lateral margins are generally more or

less carinate, but not ampliated. The “ Beosaria” are distinguished by these lateral

pronotal margins being more or less laminated and ampliated, and having the antenne

nude, or sometimes slightly pubescent, which in the “ Gonianotaria” have the three

basal joints rigidly hirsute or setose. The “ Lethearia,” with which Stal himself incor-

porated his division ‘ Drymaria,” are stated by him to be differentiated from all the

preceding divisions by the following character :—“ Lateribus segmenti quarti ventralis

maculis opacis duabus, a margine postico segmenti longe remotis, interdum quoque

posterius macula opaca tertia instructis.” After a prolonged study with all these divi-

sions, and especially with the last-named, I have found Central-American forms which

did not rigidly appertain, so that it was possible, by wrong divisional differentiation, to

add confusion to the study of the whole group. I have, however, without using these

divisional names, endeavoured to group the species in accordance with Stal’s views, not

so much (in my opinion) for their special classificatory value, but rather for the aid

thus afforded to the study of faunistic affinities and distribution, as Stal has in this way

enumerated the different extra-European species with which he was acquainted.

NEOCATTARUS, n. gen.

Head, including outer margin of eyes, a little broader than anterior margin of pronotum. Eyes prominent.

Ocelli situate at base of head, and separated from each other by about twice the distance that separates

them from the eyes. Antennz with the basal joint more or less passing the apex of the head, second

joint about or a little more than twice the length of the first. Rostrum about reaching intermediate

cox, first joint subequal in length to that of head. Pronotum strongly and transversely constricted, the

anterior lobe narrower but a little longer than posterior lobe. Costal margin of corium concavely

sinuated. Anterior femora incrassated and spined beneath.

This genus appears to be allied to Cattarus, Stal, and Pamphantus, Stal, from both

of which it. differs by the length of the second joint of the antennz and of the

first joint of the rostrum, and the relative proportions of the pronotal lobes. From

Cattarus it also differs by the position of the ocelli, and from Pamphantus by the

sinuated costal margin of the corium.

Head and pronotum dull opaque black ; posterior lobe of pronotum somewhat paler, and with the lateral and

basal margins narrowly dull ochraceous ; head and anterior lobe of pronotum indistinctly rugulose, poste-

rior pronotal lobe sparingly but distinctly punctate. Antenne ochraceous, the apical joint somewhat

infuscated ; second joint longest, third and fourth a little shorter than second, and subequal in length.

contains a small ochraceous spot, and a broad, black apical marginal fascia, which becomes suddenly

attenuated as it approaches the central fascia. Membrane pale fuscous hyaline. Body beneath piceous, ©

posterior angles of metasternum pale ochraceous ; legs dull obscure ochraceous, intermediate and poste-

rior femora more or less castaneous, apices of tarsi pitchy.

apical margin broadly black, becoming attenuated towards inner angle. Membrane fuscous, with the base

somewhat paler. Body beneath piceous, anterior lateral margins and posterior angles of metasternum

pale ochraceous. Femora piceous, apices dull ochraceous; tibie piceous, with their extreme bases dull

ochraceous ; tarsi ochraceous, with their apices pitchy.

Long. 4 millim.

Hab. Panama, Bugaba (Champion).

This species is allied to V. firmus, from which it differs by the very different relative

lengths of the antennal joints, the different colour of the posterior lobe of the pro-

notum, &c.

3. Neocattarus. vigens, n. sp. (Tab. XIX. figg. 21 & 22.)

Megalonotus, Fieb. Eur. Hem. pp. 47 & 181 (1861).

In this genus the anterior lobe of the pronotum is much longer than the posterior,

and has the lateral margins strongly rounded, the second and third joints of the rostrum

are subequal in length, and the anterior femora are incrassated and have a distinct

subbasal spine. —

This is a Palearctic genus, of which Pamera una, Say (identified as a Mega-

1. Rhyparochromus plenus, n. sp. (Tab. XIX. fig. 23.)

Head and pronotum bronzy black, the last coarsely punctate, but more prominently so on the posterior lobe ;

seutellum bronzy black, and, excluding a central carinate line, very coarsely punctate. Corium dull

ochraceous, the clavus much suffused with pale piceous, a pale piceous subcostal fascia (ill-defined) not

reaching base and terminating about centre, where it amalgamates with a large bright black patch, which

ochraceous ; legs black ; apices of femora, apical portions of tibia, and tarsi dark ochraceous.

Long. 3 millim.

Hab. Guatemaa, Quezaltenango (Champion).

The very different markings and coloration will alone distinguish this species from

TRAPEZONOTUS.

Trapezonotus, Fieber, Eur. Hem. pp. 50 & 190 (1861); Stal, Ofv. Vet.-Ak. Férh. 29: 7, p. 55

(1872); En. Hem. iv. p. 158 (1874).

In this genus the principal characters to be relied on, especially with reference to

allied American genera, are the shape of the head and pronotum, both of which are

transversely broad and not longer than broad. The basal joint of the antenne also

only just passes the apex of the head. |

This is another Palearctic genus, being well represented in Europe, where ten species

are enumerated by Dr. Puton. One of these is also recorded by both Mr. Uhler and the

late Dr. Stal as found in North America; and a second American species has been

described from Texas. Neither of these has yet been received from Central America,

from which, however, I am able to describe the following new species :—

1. Trapezonotus caliginosus, n. sp. (Tab. XX. fig. 3.)

Head black, pilose. Pronotum with the anterior lobe black, subrugulose, and finely punctate, the posterior

lobe ochraceous, coarsely and, in some places, confluently punctured with black ; the margins ochraceous

and impunctate. Scutellum piceous, very finely and sparingly punctate, the apical margins more distinctly

and coarsely punctate. Corium ochraceous, coarsely and, in some places, confluently punctured with

black; the lateral margins impunctate. Membrane pale fuscous, the margins and veins ochraceous.

Antenne pale brown, the apical joint darkest ; first, second, and third joints pilose; second joint longest,

fourth joint a little longer than third. Body beneath piceous, lateral margins of sternum and acetabula _

ochraceous; legs variable in coloration, in some specimens almost uniformly ochraceous, in others with

the anterior femora (excepting apices) and broad apical annulations to intermediate and posterior femora

more or less castaneous.

Long. 4 to 5 millim.

Hab. GuatEMaLa, Quezaltenango, Quiche Mountains (Champion) ; Panama, Volcan de

Chiriqui, 4000-6000 feet (Champion).

In this genus considerable allowance must be made for the amount of ampliation of

TRAPEZUS. 217

the lateral margins of the pronotum, a character which varies in extent among the

European species, and which is particularly minimized in the Texan species 7. rufipes,

Stal. In 7. caliginosus the extent of this ampliation may be described as of a somewhat

intermediate character.

TRAPEZUS, n. gen.

The characters of this genus are in the main those of Trapezonotus; but differential

ones are found in the length of the head, which equals, or is a little longer than, the

width ; the head, including outer margin of eyes, is distinctly narrower than the anterior

margin of the pronotum ; the anterior femora are thickened, but not spined ; and the

colour is shining, not opaque.

1. Trapezus trimaculatus, n. sp. (Tab. XX. fig. 4.)

Head piceous, apex ochraceous ; eyes dull brownish. Antenne sparingly pilose, with the first and second joints

ochraceous, the third and fourth piceous; second and fourth joints subequal in length, third joint a little

longer than basal, which slightly passes the apex of head. Pronotum with the anterior lobe black, with

a few scattered punctures ; posterior lobe ochraceous, with fuscous suffusions, and sparingly but distinctly

punctate, the margins ochraceous and impunctate. Scutellum black, very finely but sparingly punctate,

with three linear ochraceous spots, one at apex and two lateral about centre. Corium ochraceous,

coarsely and darkly punctate, the punctures arranged in linear series, between which the ground-colour

appears as pale ochraceous fascie, of which there are two claval, two subclaval, and two discal, between

which near apical margin, which is also pale ochraceous, are two elongated and irregular pale ochraceous

spots; lateral margin also pale ochraceous. Membrane pale fuscous, the apical margin pale hyaline, the

base somewhat ochraceous. Body beneath piceous; posterior angles of pro- and metasternum ochraceous,

lateral margins of sternum narrowly dull ochraceous, Legs ochraceous.

Long. 33 millim.

Hab. GuateMa.a, near the city (Champion).

2. Trapezus apicatus, n. sp.

Closely allied to the preceding species ; but scutellum with the apex only ochraceous, and antenne with the

second joint distinctly longest, and third and fourth joints subequal in length; the third joint has only

the apex piceous.

Long. 33 millim.

Allied to 7’. apicatus, but larger ; antenne longer, but with the same relative length of joints; pronotum more

narrowed anteriorly and more concave at base. Corium with a short subclaval fuscous fascia, a wide trans-

verse black fascia crossing at inner angle, and apical margin and angle also widely black.

Gonianotus has been differentiated from Emblethis, an allied European genus found

- in America, and both of which belong to Stal’s division Ganianotaria (ante, pp. 212 &

213), in the following manner by St&l:—“‘Spatio inter antennas et oculos longiore,

antrorsum haud angustato; tuberculis antenniferis latioribus, apice late truncatis,

angulo apicali ultra locum insertionis antennarum prominulo.”

Dr. Puton has enumerated two European species of this genus, one of which is also

recorded in North America, and has been received by us from Guatemala.

Mr. Uhler ? remarks on this species, as found in North America, that it “is probably

an importation from Europe, as it offers no difference from specimens which I have

examined from Germany. Several of the varieties found in Europe are also to be met

with in this country.” In two specimens, received from Guatemala, I can detect neither

specific difference nor special variation.

EREMOCORIS.

En. Hem. iv. p. 163 (1874).

The body is opaque; the first joint of the antenne passes the apex of the head by

more than its apical half; the posterior lobe of the pronotum is distinctly anteriorly

depressed, and is likewise shorter than the anterior lobe. ‘These are some of the

principal characteristics of this genus, whose area is a very wide one. Dr. Puton

enumerates four European species; one and, at present, one only is known in the

Nearctic Region, whilst we have received the following undescribed species from

Guatemala. .

1. Eremocoris tropicus, n. sp. (Tab. XX. fig. 7.)

Head piceous ; antenne piceous, the base of the first joint luteous; second, third, and fourth joints subequal in

length. Pronotum castaneous, with the lateral margins, excepting base, ochraceous ; the anterior lobe

central, piceous spots, and a smaller one at each basal margin, and with a central, pale, longitudinal,

ochraceous line. Scutellum piceous, finely and indistinctly punctate. Clavus dull testaceous, with the

central portion ochraceous. Corium dull testaceous; the basal third and a large central spot a little

before apex ochraceous; there is also an obscure and somewhat pale spot on each side of disk near claval

margin of metasternum ochraceous ; anterior femora piceous, with their apices ochraceous ; intermediate

and posterior femora ochraceous, broadly annulated with fuscous near their apices; tibie and tarsi

Long. 4 millim.

Hab. GuatemMata, Quiche Mountains (Champion).

This species is closely allied to LE. ferus, Say, of which the Rhyp. borealis, Dall., is

stated by Uhler and Stal to be a synonym. From this it differs by the different colour

of the legs, marking of the membrane, &c.

GONATAS, n. gen.

Antenne with the three basal joints hirsute, first joint passing apex of head, second longest, attenuated at its

base. Head rather longer than broad and, including outer margin of eyes, a little narrower than interior

margins moderately ampliated; the anterior angles rounded, and with an obscure central transverse

impression ; the posterior margin slightly concave at base of scutellum. Scutellum triangular, a very

little longer than broad. Anterior femora moderately thickened, somewhat setose beneath, and with a

few very small spines beneath near apex ; intermediate and posterior tibie setose ; first joint of posterior

tarsi almost twice as long as second and third joints together. Rostrum reaching intermediate coxe ; first

joint about equal in length to that of the head ; second longest, reaching anterior coxe. Abdomen beneath

pilose.

submarginal nodosities on each side, and a similar one near apex. Corium ochraceous, much suffused with

piceous, sparingly punctate; basal costal margin ochraceous and impunctate. Membrane pale fuscous.

Body beneath piceous ; femora piceous, with their apices ochraceous; tibise ochraceous, with their apices

pitchy; tarsi ochraceous, their apical joints more or less pitchy. Intermediate and posterior tibie

coarsely and darkly punctate, with a pale ochraceous levigate line on each side, parallel with the apical

half of scutellum. Corium black, with the veins, base, and claval margins ochraceous ; the costal margin

and a large irregular subapical spot pale luteous. Membrane fuscous, with the base and veins paler.

Body beneath shiny black; coxe and femora dark castaneous; rostrum, tibie, and tarsi pale ochraceous.

The rostrum reaches the intermediate cox; the abdomen is pale ochraceously pilose; the tibie are strongly

setose ; and the pronotum has the base very slightly concave. .

Long. 43-5 millim.

Hab. Guaremaua, San Gerénimo, Paraiso, Chiacam (Champion); Panama, Bugaba

I include this species in the genus, though it differs from E. typicus in the length of

the rostrum and the less concave basal margin of the pronotum. The other characters

appertain, however, to the generic diagnosis here given.

Pyrrhocorina, Stal, En. Hem. i. p. 90 (1870).

This family is separated from the Lygaide by the absence of ocelli. It is of

generally universal distribution, and has been divided by Stal into two subfamilies, both

of which are represented in Central America.

Subfam. LARGINA.

Largida, Stal, Hem. Afr. iii. p. 1 (1865).

Largina, Stal, En. Hem. i. p. 90 (1870).

Largide, Walk. Cat. Het. v. p. 163 (1872).

The character used by Stal for the separation of this subfamily is found in the female,

in which the sixth ventral segment is fissured to the base.

The Largine are widely distributed, and, as at present known, are most numerously

represented, both in genera and species, in the Neotropical Region.

This species is of a very variable nature, the bright vitte and fascie to the pronotum

and corium becoming frequently almost obsolete. My specimen from Panama agrees

well with Herrich-Schaffer’s figure.

Eyes moderately stylated.

Base of metasternum and basal joint of abdomen greyish or ochraceous.

2. Largus subligatus, n. sp. (Tab. XX. fig. 11.)

Head black, shining, sparingly pilose. Antenne black, the apical joint somewhat paler; basal joint distinctly

incrassated at its apex, third joint very short, second longer than third, a little shorter than fourth, basal

joint longest. Pronotum with the anterior lobe shining black, the posterior lobe shining piceous, coarsely

_and thickly punctate, the posterior margin red and impunctate ; scutellum piceous, pilose, coarsely punc-

tate, with its extreme apex sometimes obscurely reddish. Corium dull reddish; basal portion of clavus

and a very large subtriangular apical patch on corinm (the apex of which in some specimens extends

nearly to base) black. Membrane very pale ochraceous. Body beneath black; sternum and posterior

segmental margins to abdomen greyish tomentose (this tomentosity, except in carefully captured speci-

mens, is more or less obsolete). Legs black, pilose; anterior femora armed with two subapical spines, one

long and prominent, the one near apex subprominent. Rostrum black, reaching intermediate coxe.

Long. 15~19 millim.

Hab. Guatemaua, San Gerénimo, Tocoy (Champion).

The females in all the specimens examined are considerably larger than the males.

The species principally varies, as already pointed out, in the amount of black suffusion

to the corium, caused by the extension or retrenchment of the apical triangular

patch.

222 HEMIPTERA-HETEROPTERA.

3. Largus affinis, n. sp. (Tab. XX. fig. 12.)

Head shining black and pilose, the base with a narrow reddish transverse line; antennse black, pilose, base of

first joint reddish, third joint very short, second a little shorter than fourth, basal joint longest. Pronotum .

reddish, the lateral margins and anterior lobe reddish ; anterior lobe with the frontal margin ochraceous,

preceded by black punctures, with two large irregularly rounded black spots on its disk, and its posterior

margin irregularly punctured with black; posterior lobe thickly and coarsely punctured with black,

excepting posterior margin, which is broadly ochraceous and impunctate. Scutellum reddish ochraceous,

covered with coarse black punctures, which are confluent at base, and with a faint, central, pale, longi-

tudinal line. Corium reddish ochraceous, coarsely covered with black punctures, which, becoming con-

fluent on disk, form an irregular transverse spot; the apical margin black, and the costal margin broadly

ochraceous and impunctate. Membrane pale ochraceous and unicolorous. Body beneath piceous; anten-

niferous tubercles, base of rostrum, buccule, acetabula, bases of coxe, anterior margin of prosternum,

posterior margin of pro-, meso-, and metasternum, and lateral margins of sternum and abdomen more or

less ochraceous. Abdominal segments with their posterior margins greyish tomentose. Legs black,

pilose ; anterior femora armed beneath with two strong subapical spines, one long and prominent, the

. other, near apex, subprominent. Rostrum black, reaching intermediate coxe.

Long. 17 millim.

Hab. Guatemata, San Gerénimo (Champion).

We have received but one example of this species from Mr. Champion ; it is allied

to L. subligatus, but differs by the less levigate structure of the anterior pronotal lobe,

the different colour of the corium and base of antenne, and also by the various ochra-

ceous sternal spots.

Base of metasternum sometimes pale coloured ; abdomen concolorous.

In his ‘Enum. Hem.” Stal placed his Z. convivus in the section of species which have

the metasternum generally concolorous ; but in a typical specimen, identified by Stal and

kindly submitted to me for inspection by Dr. Aurivillius, the posterior margin of the

metasternum is distinctly reddish. It is a most variable species: even in the Mexican

specimens now before me the colour of the corium varies from black to red, as in the

specimens figured; the base of the metasternum is reddish in some specimens, con-

colorous in others; whilst the red coxal spots are almost entirely absent, or not only

present, but even the bases of the femora are also red, thus approaching L. succinctus,

a species which, when specimens have been collected from New Mexico, I shall not be

surprised to find claiming Z. convivus as a varietal form.

A typical Mexican specimen in the Stockholm Museum is here figured. This species

also varies in the colour of the corium, which in some varietal forms is red. Its only

distinctive character from L. convivus is the more elongate form of the pronotum and

abdomen. Stal1, in his “ Differentia Specifica,” wrote “ pectore pedibusque immacu-

latis;” but this, when a series of Mexican specimens are examined, proves to be

incorrect, as it resembles L. convivus in these respects, being either totally without

these markings, or having even the bases of the femora red, as in extreme forms of the

other species.

I have been quite unable to separate Z. cinctus, H.-S., in all its varietal phases

from L. varians, Stal, with its number of varietal forms described by that author.

There is little doubt that had Stal been able to examine the long series of Central-

American specimens now before me, he would not have described his Colombian speci-

mens as a distinct species. The four specimens figured, of which figs. 16, 17, and 19

are from Panama and fig. 18 from Guatemala, show the varietal extremes; but even

here it is evident that some of the Panama specimens approximate more closely to the

Mexican type than do those from Guatemala. Stal put considerable reliance on the

colour of the membrane of his LZ varians, “ venis concoloribus;” but in some Bogota

specimens in my own collection the veins are dark, and this character is uncertain

throughout the whole series from various habitats.

Having been enabled to examine typical specimens of the two forms described

by Stal, I can detect no specific differences of a structural character, but only what

to me appears colour-variation, and that in a direction which is common in other

species of the genus. Stal certainly did not, especially in his later years and more

matured views, err in the direction of ultra specific nomenclature; and though these

descriptions were published in 1861, the two described “species” are stated to be

“ valde affinis.” Fig. 20 is that of the typical L. bipustulatus, Stal; and fig. 21 repre-

sents the form described by Stl under the name of L. socius, and redescribed by Walker

as L. pulverulentus. |

FIBRENUS.

Fibrenus, Stal, Ofv. Vet.-Ak. Forh. 1861, p. 195; En. Hem. i. p. 90 (1870).

This is an easily recognized and well-marked genus, having the anterior coxe spined,

and the anterior lobe of the pronotum in the male sex very tumid.

Two species of Fibrenus are described, both of which have been received from Central

America.

1. Fibrenus globicollis. (Tab. XX. figg. 24, 25.)

Largus globicollis, Burm. Handb. i. 1, p. 282. 2’.

Hab. Panama (coll. Dist.), Bugaba (Champion).—CoLomBia, Buenaventura (Dr.

Thieme, coll. Oberthiir) ; Braziu, Para 1 ?.

This is a very variable species, and is closely allied to the following species, F. gibbi-

collis, Stal; in fact, beyond its constantly smaller size, there is little structural character

to warrant its separation. Stal?, in specifying the differences between the two species,

writes “metastethio toto nigro, nec postice flavescente.” This is not the case with a

long series of Bugaba specimens, though applying to other Panama examples in my

own collection. Stal further observes, “segmentis flavescentibus ventris &c.,” which,

on the contrary, apply to the Bugaba series, but not to the other Panama specimens

referred to, in which the abdomen is totally black. Again, in the Bugaba form of the

species the posterior lobe of the pronotum is red, whilst in my black-abdomened Panama

specimens the posterior margin of that lobe only is red, as described by Burmeister.

2. Fibrenus gibbicollis. (Tab. XXI. fig. 1.)

Fibrenus gibbicollis, Stal, Ofv. Vet.-Ak. Férh. 1861, p. 198. 1’; En. Hem. i. p. 96. 27.

Hab. Muxico1?, Oaxaca ?, Jalapa (Hoge), Valladolid in Yucatan (Gaumer); Britis

Honpouras, river Sarstoon (Blancaneaux).

This appears to be the northern representative of the last species, and is also of a

very variable character as regards colour, though constant in respect of size. The

variation principally applies to the pronotum, of which the posterior lobe has a broad

red hinder margin, varying in that respect until in some specimens it is totally black. A

specimen from British Honduras, somewhat intermediate in that respect, is here figured.

THERANEIS, 225

THERANEIS.

Theraneis, Spin. Ess. Hém. p. 179 (1837) ; Stal, En. Hem. i. p. 90 (1870).

This genus differs from Mibrenus in having the anterior coxze unarmed; and from

Largus it is distinguished by the elongated body and the non-dilated lateral margins of

the corium. ‘The head is transversely excavated between the eyes.

Three species have been recorded, all Neotropical, and occurring south of our fauna ;

to these may be added the two from Central America here described.

1. Theraneis pulchra, n. sp. (Tab. XXII. fig. 1.)

Black ; antenne with the second, third, and fourth joints ochraceous, the second with the extreme base and

the fourth with the extreme apex fuscous. Corium and lateral posterior angles of the pronotum reddish

ochraceous. Apical angle of corium and margins of membrane greyish white. Anterior portion of head

above, anterior and posterior margins of frontal lobe of pronotum, and a central longitudinal line to posterior

pronotal lobe pale greyish pubescent. Body beneath sparingly covered with greyish pilosity. Tibiz palely

setose, tarsi pale brownish.

Antennz with the first and fourth and the second and third joints subequal in length; posterior lobe of

pronotum thickly and coarsely punctate, scutellum more faintly so; anterior femora armed beneath with

two spines near apex, one considerably larger than the other.

Long. 8-94 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet, Bugaba (Champion).

This species is allied to 7. constricta, Stal, which was recorded from Colombia, and

from which it differs by the different colour of the antenne, and the unicolorous clavus

and corium, black and opaque membrane, &c.

2. Theraneis dissimilis, n.sp. (Tab. XXI. fig. 24.)

Head black, thickly covered with greyish pilosity ; antenne black, first and fourth joints longest and subequal

in length, second longer than third, which is shortest. Pronotum pale ochraceous, anterior lobe (excluding

lateral and anterior margins) and two large subquadrate spots at base of posterior lobe pale brownish ; the

anterior lobe is defined posteriorly by a transverse row of very deep, coarse, dark punctures ; and there are

a few scattered but paler dark punctures between the basal subquadrate spots. Scutellum fuscous, with

the apex more or less ochraceous. Corium pale ochraceous, a large subtriangular spot on centre of disk,

and clavus (excluding margins) ferruginous. Membrane ferruginous. Head and body beneath, rostrum,

and legs fuscous or ferruginous ; anterior, posterior, and lateral margins of prosternum, posterior margins

~ of meso- and metasternum, coxe, lateral margins and a central longitudinal fascia to abdomen (the last

not reaching beyond fourth abdominal segment) ochraceous; tarsi beneath dull ochraceous,

Long. 9-10 millim.

Hab. Costa Rica, Cache (Rogers); Panama, Bugaba (Champion).

Var, a. Above with the ferruginous markings paler, but larger, and becoming more or less suffused with the

ochraceous ground-colour, which is also darker.

Var. b. Above with the ferruginous markings larger, and on corium occupying the whole of disk, with the

exception of the lateral and apical margins ; clavus, with the exception of apical margins, totally ferruginous ;

membrane somewhat abbreviated, exposing apex of upper surface of abdomen, which is ochraceous.

Three specimens only of this species have been received, two from Costa Rica and

one from Panama; and as they all vary, it is probable that 7. dissimilis must be of a

very protean character. The two Costa-Rican specimens represent the type (which is

figured) and the var. a; and the specimen sent home from Bugaba by Mr. Champion

is described as var. 5.

STENOMACRA.

Stenomacra, Stal, En. Hem. i. pp. 90, 97 (1870).

This species is of a variable character. In some specimens almost the apical half of

the scutellum is luteous, whilst the femora are either wholly luteous, as in Herrich-

Schaffer’s figure, or have their extreme apices concolorous with the tibie; and some-

times the apical halves of the posterior femora are also fuscous, as in the variety here

figured, which is from Guatemala, similarly marked specimens from Mexico being

contained in the Vienna and Berlin Museums. ‘These varieties do not constitute

local races.

eyes large and globose, situate about the centre of each lateral margin. Pronotum subequal in length to

head, anterior lobe longest and subglobose. Scutellum slightly gibbous. Body linear; corium and

membrane much abbreviated. Rostrum reaching anterior coxe.

This genus is allied to Arhaphe, but differs by the elongate and linear body, the

circular and globose head, &c.

Black, sparingly but distinctly pilose; corium warm ochraceous, membrane greyish with a large apical

fuscous spot.

Antennz with the first and fourth joints subequal in length, second a little longer than third, which is

shortest ; head coarsely punctate ; pronotum with a deep and broad impression separating the anterior

distribution thus being in contrast with that of the Largine.

Pyrrhocoris is so distinct in structure and appearance from the other genus alone

enumerated in this work, that the figure of one of its species here given will convey a

better idea of its structural characters than any comparative diagnosis, which in this

case is almost impossible from the absence of allied genera.

The inclusion of this well-known European insect in the Central-American fauna is

based on the fact of several specimens having been brought home by Van Patten from

Costa Rica. It probably owes its introduction there to accidental circumstances. In

the North-American fauna, which is not only similar to the Palearctic, but also

This genus and one close ally possess a fundamental difference from the other

genera of the subfamily, as pointed out by Stal, in having the wings complete and

without a hook. Its species are very widely distributed, and found throughout the

tropical and subtropical portions of the world ; and their wide variation in colour and

markings, especially as found in Central America, affords perplexing features to their

right discrimination and identification. The general form and contour is often a trust-

worthy guide; but the colour differences are frequently misleading, unless a long series

is examined.

Mr. Uhler +, who had evidently examined a large series of specimens of this species,

truly observes :—‘‘In some varieties from Mexico the head, pronotum, and corium are

entirely black; and from this to the variety with only a point of black on the middle of

the corium every variety occurs.” To this list may be added varieties in my own

collection, in which the corium is totally ochraceous or only very slightly infuscated.

The Guatemalan specimen here figured represents one of the very dark varieties.

According to Mr, Uhler‘*, this species in Hayti “abounds in gardens, and affects

small growths in damp or low grounds.”

sternum and abdomen is black and not red; the femora piceous.

Hab. Guatemaa, San Gerénimo, San Juan (Champion); Costa Rica, Cache (Rogers).

I have felt constrained to regard this as a distinct species, or, at all events, to sepa-

rate it under a distinct name, in consequence of the constant colour differences, especially

those of the underside. I have examined nine specimens, which exhibit no variation

in this respect, whilst in a series of Mexican examples of D. flavo-limbatus, including a

typical one from the Stockholm Museum, the red and not black markings are equally

constant.

Two Costa-Rican specimens are here figured.

5. Dysdercus incertus, n. sp. (‘Tab. XXI. fig. 7.)

Head red, with a basal line, the apex, and eyes black ; antenne black, with the extreme base of the first joint red,

first joint a little longer than second, third short (remainder mutilated). Pronotum with the anterior lobe

red, the posterior lobe ochraceous; the first with the lateral margins ochraceous, and the anterior collar

white, bordered inwardly with black ; posterior lobe with a large discal black spot. Scutellum black. Corium

ochraceous, with a very large and irregularly shaped black spot occupying nearly the apical third; clavus

with a central longitudinal black streak. Membrane black, the apex pale fuliginous, and the apical margin

whitish. Head beneath red, body beneath ochraceous, anterior and posterior margins of prosternum,

posterior margins of meso- and metasternum, acetabula, and posterior segmental margins whitish ;

anterior margin of prosternum inwardly margined with black; basal disks of abdominal segments

infuscated. Legs with the femora obscure castaneous, tibie and tarsi fuscous, coxe and trochanters

ochraceous. Rostrum obscure ochraceous, with the apex black, and just passing posterior coxee.

as constituting in itself a new species. I have inclined to the last view; and the dis-

tinct markings of the corium and the colour of the apex of the membrane favour that

conclusion.

This species is of a very protean character. ‘The head is either red as in fig. 15,

spotted with black as in fig. 11, or wholly black as in fig. 12. The scutellum is gene-

rally black; but amongst Mexican specimens it is sometimes found to be ochraceous.

The anterior margin or collar of the pronotum is usually white, but sometimes marked

with black as in fig. 11. The femora are either reddish or partly so, or wholly black,

as shown by the varieties here illustrated; and the abdomen beneath is more or less

prominently banded with black.

A specimen from British Honduras is represented by fig. 11, and figg. 12 & 15 are

7. Dysdercus splendidus, n. sp. (Tab. XXI. fig. 14.)

Head and base of first joint of antenne red; eyes and antennew (excepting apical joint, which is pale fuscous)

black; pronotum red, anterior collar white, inwardly margined with black, and with a large basal spot

occupying nearly half of disk black, margined anteriorly with a yellow transverse line; scutellum pale

yellow ; corium white, basal costal margin and base of clavus pale yellow, and with a large irregularly

shaped black spot about centre of costal margin; membrane black, with a narrow pale margin ; head and

body beneath reddish ;. anterior and posterior margins of prosternum and posterior discal portions of second,

third, and fourth abdominal segments whitish; meso- and metasternum, coxe, abdominal base, and

posterior margins of fifth and sixth abdominal segments yellow; legs piceous, femora more or less

reddish ; rostrum red, with the apex black, and reaching a little beyond posterior coxa.

Anterior femora armed beneath with two spines near apex.

Long. 13 millim. .

Hab. Panama, Bugaba (Champion).

It is with considerable diffidence that I have described as a distinct species this very

strongly and beautifully marked insect; and, though apparently unlikely, I shall not

be surprised to find it eventually proved to be but an‘extreme varietal form of the

protean D. concinnus.

and clavus black. Corium ochraceous, with a large transverse black macular fascia crossing at inner

angle. Membrane black. Head beneath red; body beneath black; anterior and posterior margins of

prosternum, posterior margins of meso- and metasternum, acetabula, and posterior margins of second,

third, fourth, and sixth abdominal segments pale Juteous; legs black, cox red, rostrum piceous and

reaching base of third abdominal segment. Anterior femora armed with two short spines near apex.

Herrich-Schaffer’s drawing is so useless for any practical purpose, that we have re-

figured the species, and also two of its varietal forms. The variation pursues a somewhat

similar course as in other species. Thus in fig. 17 the scutellum is wholly ochraceous,

in fig. 16 it has the base black, whilst it is wholly black in the Mexican specimen

represented by fig. 18. A specimen from Costa Rica is represented by fig. 16; and

ochraceous, first and second joints subequal in length, fourth longest, and third shortest. Extreme apex

of head spotted with black. Pronotum with the anterior collar whitish, inwardly margined with black, and

with the anterior lobe marked off by a very deep transverse incision. Head and body beneath ochraceous.

Anterior and posterior margins of prosternum, posterior margins of meso- and metasternum, acetabula, and

posterior margins of abdominal segments broadly whitish, which is more or less distinctly narrowly

Prof. Berg ® has given Mexico as a habitat for this species, but I have failed to find

any authority for the statement, nor have I seen the species in any of the numerous

Mexican collections which I have been able to examine.

Like other species of the genus, it is of a very variable character, both the scutellum

and head being sometimes ochraceous, and sometimes black. In some varieties the

corium has also the apex broadly black as in Hahn’s figure? ; but this form of the

The members of this family are readily recognized by the elongated and four-jointed

antenne, of which the second joint is frequently more or less thickened at its apex, and

the two terminal joints are always more or less slender, and also, and principally, by the

corium terminating in a distinctly differentiated section, called the cuneus.

If we except a very considerable knowledge of the Palearctic Capside, and a less

acquaintance with those of the Nearctic Region, we may safely presume to say that

those of the Ethiopian, Oriental, and Australian Regions are practically unworked and

unknown. Of the Neotropical fauna the late Dr. Stal described many from Rio

Janeiro; and Dr. Carl Berg has recently done the same for those of the Argentine

Republic, whilst owing to the unexampled success of our collector Mr. Champion

in procuring specimens of this family both in Guatemala and Panama, very much

additional knowledge has been acquired. Mr. Champion’s captures in Central America,

the description of which forms the ground-work and speciality of the following pages,

are, without doubt, the largest and most extensive contribution to our knowledge of

the Capside that have ever been, as yet, brought from the tropics; and from their

multiplicity of generic forms, their extreme diversity of type, and their frequently extra-

ordinary mimetic analogies with representatives of other families, they create an ardent

desire to know more of the exotic members of this little-worked family.

As might be anticipated, the acquisition of so much material belonging to an

unworked field has necessitated not only the description of a large number of species,

but the erection of numerous new genera for their reception.

MIRARIA. 230

As regards their systematic arrangement, I have advanced no new method (a course

impossible by the exigencies of time and the scope of an extensive faunistic work), but

have followed in most essential particulars the classificatory scheme formulated by

Dr. Reuter in 1875, which is in conformity with the views and practice of the late

Dr. Stal, and thus in unison with the system adopted for the previous families.

A superficial acquaintance with American Capside would lead, and has inclined

excellent authorities, to the opinion that European genera are largely included in the

fauna. A better acquaintance, however, supported by sufficient material, abundantly

proves that the family is not peculiar in this respect, but in America possesses a

distinctive faunistic character, embracing a number of well-marked and often extremely

specialized genera.

Subfam. CAPST NA.

Myridina, Berg, Hem. Argent. p. 117 (1879).

In this subfamily the ocelli, as stated by Dr. Reuter, are “haud distinguendi.”

All comparative generalizations as to the geographical distribution of the Capsine

are rendered for a long time hopeless by the little attention hitherto paid-to their

collection in tropical regions. When we reflect that the Capsine constitute one of

the most numerous group of insects, and that collectors have been enabled, regardless

of time and money, and at their own risk of health and life, to add to our knowledge of

the insect world, we must deplore the circumstance that size and beauty have been the

incentives to their exertions, and that it remains for another generation to deal with

some of the obscure, but most numerous and instructive, families of insects.

Division MIRARIA.

Miraria, Reuter, Bih. Vet.-Ak. Handl. ii: 1, p. 5 (1875, incl.).

In this division I recognize the genera whose species have the head distinctly

longitudinally sulcated between the eyes, and the antenne inserted on the lateral

margins of the head in front of the eyes.

I have allowed this division to embrace considerable diversity of generic form; but in

dealing alone with one fauna, or rather with a portion only of one fauna, I have thought

it best to avoid, as far as possible, increased divisional separation, until the family, as a

whole, is generally more worked and better known.

The Miraria have probably an almost world-wide distribution; and in America

we know that they are distributed throughout both the Nearctic and Neotropical

Regions.

I have felt little hesitation in identifying a single Mexican specimen as belonging to

the above species ; and there seems little doubt that both Dr. Reuter’s and Mr. Uhler’s

description refer to the same insect. Both their publications bear date 1875, but I

give the priority to the first as being the earliest received, at least in this country.

2. Miris guatemalanus, n. sp.

Allied to M. affinis, but larger ; the colour pale ochraceous; antennz with the basal joint finely but strongly

pilose, the second joint with its apex more or less distinctly infuscated. Head obscurely pilose, the central

sulcation distinct and narrow, with a longitudinal fuscous fascia on inner side of eyes, and the extreme

base also more or less distinctly fuscous. Pronotum coarsely punctate, the lateral margins and a central

longitudinal line levigate and pale luteous; a fuscous submarginal fascia on each side, broadest and badly

defined near anterior margin ; the lateral angles subprominent, subnodulose, and pale luteous. Scutellum

somewhat obscurely punctate and pilose, with a central, longitudinal, levigate pale luteous line, moderately

widened at base and apex, the basal angles fuscous. Corium densely but finely pilose, the lateral margins

broadly pale luteous, widening on each side towards the cuneus, which is also pale luteous. Membrane

pale smoky ochraceous. Body beneath and legs pale ochraceous; sternum with a submarginal fuscous line

on each side ; abdomen with a marginal series of small fuscous spots ; intermediate and posterior femora

also spotted with fuscous, the last most prominently.

Long. 8-10 millim.

Hab. GUATEMALA, Quezaltenango, Volcan de Agua (Champion).

3. Miris roseus, n. sp. (Tab. XXIII. fig. 20.)

Body above purplish red. Antenne fuscous, the basal joint not prominently pilose. Head with a broad central

longitudinal luteous fascia, and a fuscous, but narrower, fascia on inner side of eyes. Pronotum ochraceous,

coarsely and darkly punctate, anterior area with two purplish rugosities on each side; the anterior and

lateral margins and a central longitudinal line levigate and pale luteous. Scutellum with the basal angles

fuscous, and with the apex luteous*. Corium and cuneus with the lateral margins pale luteous; the clavus

punctate, with its outer margin luteous. Membrane pale smoky hyaline. Body beneath and legs ochra-

narrowly of the same colour. Legs pilose, femora more or less spotted with fuscous; tibie with their

bases and apices fuscous; tarsi fuscous. Rostrum long, about reaching the second abdominal segment, its

apex fuscous.

Long. 7 millim.

Hab. Mexico, Oaxaca (Deppe, Mus. Berol.).

CREONTIADES, gen. nov.

Body elongate. Head moderately and obliquely deflexed before eyes, and with a distinct, narrow central longi-

tudinal sulcation; eyes somewhat prominent, and contiguous to the anterior margin of the pronotum ;

antenne about as long as the body; basal joint stoutest, considerably longer than the head, and sparingly

but prominently hirsute; second joint about twice the length of the first, somewhat slender, slightly

curved, and a little incrassated at apex; third joint a little shorter than the second; fourth joint about or

less than half the length of the third. Pronotum subtriangular, with a distinct anterior collar, and the

anterior margin about half the width of the posterior. Scutellum large, the disk somewhat longitudinally

raised, and the lateral margins obliquely rounded. Corium with the costal margins subparallel. Legs

long, sparingly hirsute, the tibia with long and prominent set. Rostrum reaching the posterior cox.

The length of the posterior legs and its general superficial appearance give this

genus a considerable resemblance to those comprised in the division Phytocaria; but

the central sulcation of the head and the insertion of the antenne well in front of the

eyes and at the lateral margins of the head, in my opinion clearly denote its position

in the Miraria.

Since figuring the above Mexican specimen, which was considerably mutilated, I have

been enabled to examine the type (also imperfect), in the collection of Dr. Signoret and

to again compare both of these with perfect specimens collected by Mr. Champion.

The legs are concolorous with the body, the posterior femora with their apical halves

bright castaneous, and the apices of all the tarsi blackish.

In lettering the Plate I followed Dr. Stal in considering the species as belonging to

the genus Megacelum, but on further examination I was compelled to form a new

genus for its reception as above.

MINYTUS, gen. nov.

Body subelongate, opaque. Head long, the lateral lobes slightly but angularly produced on each side in short,

obtuse spines ; central sulcation long and distinct; antenne not so long as the body, first and second

joints very strongly incrassated ; first joint pilose, about as long as the head, slightly curved outwardly

TRACHELOMIRIS.

Trachelomiris, Reuter, Ofv. Vet.-Ak. Férh. 1875, no. 9, p. 61.

This genus, founded by Dr. Reuter for the reception of a North-American species,

and also to include the Miris scenicus, Stal, a South-Brazilian species, agrees in all

its given diagnostic characters with the species which I here include in it. As I

understand it, Zrachelomiris may be easily recognized (at least from any of the genera

of Miraria here enumerated) by the elongated body, the eyes inserted about the middle

of the elongated head, the nearly conical pronotum, which is anteriorly deflexed, the

antenne longer than the body, and the long and pilose legs.

A secondary generic character appears to be afforded by a fuscous spot near the

lateral angles of the pronotum, which is described as indicative of both St&l’s and

Reuter’s species, and is also found in the one which I here describe.

1. Trachelomiris oleosus, n. sp. (Tab. XXIV. fig. 2.)

Body above fuscous, the colour shining and oleaginous. Head with five luteous spots—one on each side of eyes,

one between antennal bases, and two contiguous behind eyes; the apex shining black; antenns fuscous,

with the first joint, excepting extreme base, ochraceous, minutely spotted with fuscons. Pronotum some-

what coarsely punctate, the anterior, posterior, and lateral margins, and a central longitudinal line pale

luteous ; a large, elongated, shining black spot near each lateral angle; the transverse impression at

anterior area sometimes distinctly luteous. Scutellum transversely wrinkled, with the basal angles black ;

two basal and subangular spots, a central longitudinal line, and apex luteous. Corium with the lateral

margins pale luteous; the clavus distinctly punctate; the cuneus pale luteous, with an inner elongate

fuscous spot. Membrane pale fuscous. Legs pale reddish ochraceous, the femora thickly spotted with

fuscous ; apices of the tarsi fuscous. Rostrum pale luteous, its apex pitchy; head beneath and sternum

fuscous ; apex of head, anterior margin of prosternum, cox, trochanters, and. abdomen pale luteous.

Division VALDASARIA.

In this division I propose the arrangement of a series of genera in which, like those

of the preceding division, the head is always, though frequently obscurely, sulcated,

and sometimes more correctly to be described as excavated; the antenne are inserted

well in front, but on a level with the inner margin of the eyes.

The species thus comprised are of a more robust character than those of the Miraria,

and the colouring is bright and handsome, thus approximating towards the next

division.

PIASUS, gen. nov.

Body elongate, widest at base of pronotum. Head moderately long and porrect, somewhat deflexed towards

apex and with a distinct and somewhat broad central longitudinal sulcation on disk, which is distinctly

moderately gibbous ; eyes large and prominent, slightly directed backwards and well separated from the

anterior margin of pronotum. Antenne with the basal joint stoutest and much longer than the head;

second joint about half as long again as the first, but more slender, gradually thickened towards apex

and finely pilose; third and fourth joints short and slender. Pronotum with the posterior margin slightly

convex and more than twice as wide as the anterior margin, which is distinctly raised, the lateral

margins sinuate; the lateral angles subprominent; transversely constricted before the middle, between

which constriction and the anterior margin it is distinctly nodulose, and between the same and the

posterior margin it is coarsely punctate. Scutellum subconvex and coarsely punctate. Corium with the

lateral margins subparallel. Cuneus a little longer than broad. Rostrum reaching the intermediate coxa.

VALDASUS.

Valdasus, Stal, Rio Jan. Hem. i. p. 56 (1858) ; Walk. Cat. Het. vi. p. 47 (1873).

This peculiar and well-marked genus is easily recognized by the vertically deflexed

head in front of the eyes, which are very prominent, obliquely suberect, and contiguous

to the anterior margin of the pronotum.

Valdasus appears to be quite confined to the Neotropical Region. Only two species

have hitherto been described, one from South Brazil and the other from Mexico. Of

these the last is found in our tauna, and seven other new species are here described.

There is therefore every probability that this will eventually be found to be a most

extensive genus.

These insects were found by Mr. Champion on black fungi (to which they assimilated

in colour) attached to fallen trees. ‘They were of particularly active habits, both flying

and running, thus making their capture somewhat difficult.

2. Valdasus stellatus, n. sp. |

Closely allied to V. famularis, but differing by its darker colour above; pronotum with three linear, longi-

tudinal, pale ochraceous lines, one central and two submarginal; femora much darker than in Stal’s

species, and not doubly annulated, but with a single upper ochraceous spot. It structurally differs by

having the lateral pronotal angles distinctly subnodulose, and narrowly ochraceous at their apices.

euneus, and inner margin of cuneus ochraceous, the base of the last somewhat reddish; membrane

fuscous, its apical margins somewhat paler; the corium is narrowly at inner margin and broadly at apex

of claval margins dark velvety fuscous; legs dull obscure luteous, femora more or less distinctly biannu-

lated with fuscous, the tibiae somewhat pale fuscous; antenne fuscous, apex of second joint luteous.

Body beneath (imperfectly examined owing to the specimen being carded) fuscous; head, coxe, and

abdomen luteous, the last with a submarginal longitudinal series of fuscous spots.

The body is broad, and, excluding head and posterior margin of pronotum, very coarsely punctate, the

lateral angles of the pronotum are non-prominent but obtusely acute, and the anterior lobe or gibbous

portion is profoundly sulcated. *

The great width of the pronotum at base, irrespective of general colour and markings,

at once separates this from the two preceding species.

This genus possesses many well-marked characteristics to prevent it being confused

with any of the other genera here enumerated. The head is very broad and anteriorly

deflexed, the sulcation is broad and subfoveate, the basal joint of antenne very short

and stout, remaining joints much more slender, gradually weakening, and distinctly

and strongly pilose. ‘The cuneus is much longer than broad.

the whole, of the first joint more or less yellowish; the pronotum varies from black

with the margins brownish (as described by Signoret) to either wholly black or com-

pletely ochraceous; the corium also varies in a similar manner. The character,

however, which is constant, and in my view always indicates this protean species, is

the annulated posterior femora.

A Mexican variety belonging to the Berlin Museum is here figured.

A single example of this interesting species was obtained by Mr. Champion. It

closely resembles in colour and markings a species belonging to another section of the

Hab. GuateMALA, Aceituno (Champion).

This, like the last species, is represented (at present) by a single example, and closely

resembles in general pattern above a species in another division of the genus (R. chiri-

guina, Tab. XXV. fig. 3), from which it structurally differs in the length of the basal —

joint of the antenne. &. guatemalana is also a paler-coloured insect than &. chiriquina

and the scutellal and sternal markings are different in the two species.

This superficial resemblance of two species belonging to different sections of the same

genus, and thus structurally differentiated in what is best but inadequately described as

in a subgeneric manner, is not uncommon in other families of insects and notably in the

Rhopalocera. In some cases this has caused the erection of a number of unnecessary and

perplexing subdivisions styled genera, and has elsewhere been somewhat grandiloquently

described as affording the material for a new “ philosophical extension of the theory of

mimicry.” The factsseem to show a biological law of which we are at present in ignorance.

LOPIDEA.

Lopidea, Uhler, Hayden’s Surv. Mont. p. 411 (1872).

The shape of the pronotum—which is “ trapezoidal, about one half wider than long ;

the lateral edges carinately elevated; the middle of the posterior margin sinuately

deflexed ”—will alone separate this genus from Resthenia, to which it is closely allied.

According to our present knowledge, the geographical range of Lopidea appears to

be restricted to the southern portion of the Nearctic Region and the northern portion —

of the Neotropical.

Mr. Uhler further describes the species as variable “in the width of the pale margin

of the hemelytra and in the extent of black on the pronotum” 4, and also in the base of

the corium being ‘“‘sometimes entirely whitish” 1. It was collected on the hills of

Colorado from July to September 2, and “seems to be a mountain-loving species, and

did not occur to me on any of the lower levels on which I used the net ” .

Division PHYTOCARIA.

Phytocaria, Reuter, Bih. Vet.-Ak. Handl. iii: 1, p. 6 (1875).

In this and the following divisions the antenne are inserted on the inner side of the

eyes; and the characters which appear principally to divide the Phytocaria from the

next division are, to quote Dr. Reuter, “ Hemelytra vena brachiali distincta, cuneo

elongato-triangulari.”

As I understand and use this division, the cuneus is elongate and subtriangular and

always as long and generally longer than broad.

* These figures are too rough for any practical purpose.

COMPSOCEROCORIS.

Compsocerocoris, Reuter, Ofv. Vet.-Ak. Férh. 1875, no. 9, p. 70.

The principal characteristics of this genus appear to be the central basal sulcation to

the head, the length of the antenne (as long as the body), with the basal joint slightly

incrassated and about equalling in length that of the pronotum and half of the head

together, and the lateral angles of the pronotum obtusely acute. This genus was

founded by Dr. Reuter for the reception of a Texan species.

Of similar habits to the European genus Phytocoris and obtained by beating

(Champion). .

1. Compsocerocoris exustus, n. sp.

Ochraceous, mottled with pale brownish; pronotum with four black spots on basal margin; scutellum with

two similar spots near apex, and three or four small brownish spots arranged on inner margin of cuneus,

and one very small and obscure on each inner margin of corium near apex. Antenne ochraceous, with

the basal joint strongly setose and obscurely annulated with brownish at middle and apex; second joint

with the apex fuscous, middle of the second joint and base of the third greyish. Cuneus somewhat paler

than the corium. Membrane mottled with brownish. Femora ochraceous, annulated with brownish ;

fore and intermediate tibie with three distinct dark fuscous annulations ; posterior tibie with similar

but very obscure annulations and longly and palely setose. Body beneath (carded specimen) ochraceous

and more or less mottled as above. Two elongate fuscous spots near lateral margins of prosternum, and

one at lateral margins of mesosternum.

Long. 74 millim.

Hab. GuateMALA, Quezaltenango (Champion).

2. Compsocerocoris dubitatus, n. sp. (Tab. XXV. fig. 12.)

Allied to the preceding species, but differing in the following particulars:—The pronotum is marked with a broad,

central, longitudinal pale fascia, the eyes are dark fuscous, the second and third joints of the antenne are

concolorous and without the pale and dark markings; euneus much paler, and membrane much darker.

Long. 7 millim.

Hab. GuaTeMALA, Quiche Mountains (Champion).

It is with some doubt that I have described this form as a distinct species, though

the markings are very divergent. Dr. Reuter has not stated that sexual differences of

this nature are found in the genus, and we have received but a single specimen from

Mr. Champion, and therefore cannot decide as to the sexual problem.

3. Compsocerocoris vilis, n. sp. (Tab. XXV. fig. 13.)

Ochraceous ; basal joint of antennee much mottled and annulated with brown, the apex somewhat reddish ;

some spots within the anterior and posterior margins of eyes, four longitudinal fascia to pronotum, which

become somewhat macular at anterior and posterior margins, two spots to scutellum, a series of inner and

outer claval spots, and three spots to cuneus, situate at basal angles and apex, reddish ochraceous. FFemora

ochraceous, mottled with brownish ; the posterior femora with some obscure reddish annulations; tibiw

ochraceous, somewhat darker at bases and apices. Body beneath ochraceous, with reddish linear markings.

basal area broadly greenish, and behind the anterior collar somewhat greyish; clavus and the corium at

claval area somewhat infuscated, the outer claval margin (excluding base) very bright castaneous; disk of

corium greenish ; cuneus with the apex bright castaneous, and with a small darker spot near inner basal

angle. Membrane dull obscure ochraceous, shaded with pale fuscous, especially at base. Legs ochraceous ;

tibia outwardly and lineately fuscous ; apices of the tarsi fuscous. Body beneath ochraceous, more or less

mottled with brownish.

5. Compsocerocoris annulicornis.

Compsocerocoris annulicornis, Reuter, Ofv. Vet.-Ak. Férh. 1875, no. 9, p. 70.

Ferruginous of more or less intense hue in different specimens; antenne with the basal joint thickly irrorated

with pale ochraceous, second and third joints with their bases pale ochraceous; eyes fuscous ; pronotum

with the basal margin narrowly obscure ochraceous, and inwardly bordered by a transverse series of small

fuscous spots; scutellum with the apex obscure ochraceous; corium with the costal margin more or

less spotted with ochraceous ; cuneus variable in hue, sometimes obscure ochraceous with the apex ferru-

ginous, its inner or apical margin always spotted with ferruginous; legs ochraceous, femora (excluding

bases) annulated and mottled with ferruginous.

This appears to be a most protean and variable species, and the following notes refer

to what I consider to be but different forms of the same. In all the specimens, however,

the pronotum has the basal margin narrowly obscure ochraceous, inwardly bordered

by a transverse series of small fuscous spots.

Var. a. Kyes fuscous; second and third joints of the antenne with their bases and an annulation a little

beyond middle pale ochraceous. Tibiew distinctly annulated.

Var. 6. Second and third joints of the antennsw with their bases alone pale ochraceous.

Var. c. Resembling var. 6, but with the eyes greyish.

Var.d. Eyes greyish or fuscous; antennz as in preceding variety, colour pale and bright ferruginous ; pronotum

sometimes with two small discal dark spots; the tibie either very indistinctly or non-annulated.

Var. ¢. Resembling var. d, but with the corium, membrane, and cuneus largely irrorated with greyish.

Var. f. Third joint of the antenne distinctly and broadly black at apex ; legs as in vars. d and e.

Var. g. Antenne unicolorous, the second and third joints not pale ochraceous at base; tibiee as in the three

preceding varieties.

After a prolonged examination I can, at present, find no real specific differences

among the above divergent forms, whose variation inter se is so great, that I feel little

hesitation in placing them all under the cognomen of Reuter’s species ; and although

but one specimen really appertains fully to the description of that species, yet that

seems. so inseparably linked with the most extreme forms of the series, that their specific

unity appears to be reasonably demonstrated, and I have treated them accordingly. Even

the varietal characters given above do not at all adequately express the extremely protean

phases, both in colour and markings, that can be observed in the series of specimens now

before me, and this irrespective of local habitats to which they do not appear to be con-

fined, save and except that var. ¢ is represented alone by three specimens from Panama.

6. Compsocerocoris mistus, n. sp. (Tab. XXV. fig. 15.)

Allied to typical forms of the last species, but larger, and also differing in having the antenne: (excluding the

basal joint) black, the bases of the second and third joints being narrowly pale ochraceous, the basal joint

ochraceous, spotted and annulated with blackish, the lateral margins of the pronotum broadly blackish, &c.

Long. 7 millim.

terior tibiz distinctly curved. Antenne with the basal joint about equal to the length of the pronotum

and half the length of the head together, incrassated, pilose, and faintly but distinctly nodulated at the

extreme apex; second joint not quite twice the length of the first, its apical half incrassated ; third and

fourth extremely slender. Rostrum reaching the intermediate cox. Pronotum long, anteriorly depressed,

about twice as broad at lateral angles as at anterior margin. Scutellum large, about subequal in length

to pronotunt, the lateral angles slightly convex, the disk distinctly and longitudinally depressed and foveate,

thus rendering the lateral margins broadly and roundly subgibbous. Body pilose.

NEUROCOLPUS.

Neurocolpus, Reuter, Ofv. Vet.-Ak. Férh. 1875, no. 9, p. 69.

The antenne are the most striking features in this genus; the basal joint is distinctly

shorter than the pronotum, but very strongly incrassated, and, in the species here

referred to, subnodulose at apex; it is also densely setose, the apices of the sete being

dilated ; the second joint is twice as long as the first, with its apex strongly incrassated ;

and the third and fourth joints together are shorter than the second.

Ochraceous, thickly pilose ; antenne with the apex of the second joint broadly fuscous, the third fuscous with

the base ochraceous; margins of the lateral angles of pronotum slightly fuscous; scutellum more or less -

infuscated ; inner claval margin and two discal but broken transverse fascie to corium (one near base and

I have considerable doubt as to this being a distinct speeies from the preceding, and

think it possible that it may be included in some varietal forms of the same. However,

it is smaller in size, and the colour-differences are considerable. The difficulty in the

way of a decision arises from the fact of the type and sole representative of V. mewica-

nus being somewhat mutilated, and thus a series of Mexican specimens may probably

prove the two forms here described as distinct species to be but varietal forms of only

one.

PARACALOCORIS, gen. nov.

Body above distinctly pilose. Antennze with the basal joint incrassated, shorter than the pronotum, thickly

clothed with fine long hairs ; second joint about twice as long as first, its apex distinctly incrassated ; third

* Owing to the absence of the antenne in the typical specimen, the generic position of this species is ren-

dered, for the present, somewhat uncertain. J udging, however, from the pilose body and the subexcavated

black discal spots to the pronotum, there seems little doubt that it belongs to the new genus I have here

proposed. As the first aim of this work is of a faunistic character, I have figured many unique though

mutilated species, in order to make our enumeration as complete as possible. |

GARGANUS.

Garganus, Stal, Stett. ent. Zeit. xxiii. p. 321 (1862).

In this genus the basal joint of the antenne is longer than the pronotum and more

than half the length of the second, which is thickened and gradually attenuated at the

base and apex; the head is vertically deflexed in front of the eyes.

These characters will alone separate Garganus from the two preceding genera, to

which it is clearly allied.

This somewhat extensive genus is common in the Palearctic Region, and occurs in the

Nearctic and Neotropical Regions, and will doubtless be found to be generally and

widely distributed, when our knowledge of the exotic Capside is extended.

The differential characters between this and Paracalocoris have already been given.

In all the species here enumerated as belonging to the genus Calocoris the rostrum

about reaches the posterior coxe.

Two specimens of this species have passed through my hands, both, however, more

or less mutilated. I have therefore considered it best to place the species provisionally

in the genus Calocoris, to which it certainly has the strongest affinities, if not really

attributable to that genus.

In this genus the extreme apex of the scutellum is deflexed and curved downwards,

a character which with its subopaque coloration will sufficiently distinguish it from

the preceding genus.

Mr. Uhler remarks that this “is a very variable insect, both in colours and in the

width and thickness of the body and members. Pigmy specimens often occur in Eastern

Massachusetts. I have found it in July on the grape-vines north of Baltimore.

“The two figures of Herrich-Schaffer represent varieties which are occasionally found

in Maryland. Neither of them represents accurately the shape of the joints of the

antenne, although figure 791 is more nearly correct than the other.”

These two forms figured by Herrich-Schaffer are indeed very distinct; and though

272 HEMIPTERA-HETEROPTERA.

Mr. Uhler states they are varieties of one species; I think a mistake may have been

made in that respect, more particularly as he refers to the description as well as the

figure of C. tetrastigma, the first of which really refers to another species C. (Resthenia)

divisa, as pointed out by Stal and previously recorded here (anted p. 208).

Division CAPSARIA.

Capsaria, Reuter, Bih. Vet.-Ak. Handl. iii: 1, p. 6 (1875).

The following characters used by Dr. Reuter in his diagnosis of this division—

“cuneo breviusculo, fractura sepe profunda”—appear most easy of recognition, and, as

I understand the division and use it, the Capsaria have the cuneus shorter than in the

preceding division, but principally broader at the base. *

In Lygus the second joint of the antenne is not, or very slightly, incrassated ; the

first joint of the posterior tarsi is very little longer than the second; the eyes are

moderately exserted; the hemelytra are more or less pubescent; the cuneus mode-

rately elongated.

This genus probably occurs wherever the Capside are found.

In this genus the body is glabrous and obsoletely and minutely punctured, the

Dr. Reuter has divided his genus into two subgenera—Pecilocapsus and Metrior-

rhynchus, the first of which is, according to our present knowledge, alone represented

in this fauna. Its characteristics consist in having the basal joint of the antenne not.

longer than the head, and the rostrum not passing the anterior coxe.

Long. 6 millim. .

Hab. GuatTEMata, Totonicapam (Champion).

It is quite probable that this species may represent but varietal forms of the preceding

P. alacer, Stal. The material now before me, however, does not allow me to adopt

this conclusion.

Hab. Mexico ! (Deppe, Mus. Berol.).

This species is subject to considerable variation in colour and markings. The colour

varies from ochraceous to greenish, as the two specimens here figured sufficiently indi-

cate. Fig. 13 represents a variety which apparently possesses the maximum in dark

macular marking. In fig. 12 the submarginal black stripe to the lateral sides of the

pronotum is absent, and the black fascize to the corium are attenuated; whilst in a

specimen kindly forwarded to me by Dr. Signoret, the corium merely possesses a claval

oblique fascia and two discal spots, being the “var. 6” as described by Stal.

Fulvius, Stal, Stett. ent. Zeit. xxiii. p. 322 (1862) ; Walk. Cat. Het. vi. p. 47 (1873).

This genus is very distinct from those to which it is in this work allied, being dis-

tinguished by the more elongate body, the elongately produced head, the pronotum as

described by Stal (“ thorax leviter transversus, trapezoideus, basi truncatus, callis leviter

elevatis, margine antico haud calloso,” &c.).

Species of this genus are found running actively on the surface of fungoid growths

attached to fallen timber (Champion).

This species seems to be closely allied to . patellata, Stél, a species described

from Rio Janeiro. From the description of Stal’s species, it differs by its smaller

size, the foveate spots to the pronotum, its white pilosity, different colour of the

antennee, &c.

Cyllocoraria, Reuter, Bih. Vet.-Ak. Handl. iii: 1, p. 6 (1875).

Cyllecoraria, Reuter, Ofv. Vet.-Ak. Forh. 1875, p. 79.

As I do not, at present, clearly apprehend the distinction, in all cases, of the above

divisions proposed by Dr. Reuter, I have, to prevent confusion, and in conformity with

the course pursued at p. 212 of this work when dealing with some of the late Dr. Stal’s

divisions, placed them together. In doing this I have no wish or intention to disparage

the validity of Dr. Reuter’s work; but as this publication is primarily “ faunistic” in

character, I should, had I adopted that author’s systematic proposals, been compelled

to make even further divisional separation of genera.

The antenne being not quite so wide apart as the eyes, appears to be the strongest

structural difference of the division as here used.

founded for the reception of Capsus vitripennis, Say, a species I only know by the

figure given by Townend Glover (Ill. Ins. Hem. t. vii. f 8). Reuter’s genus is, however,

rendered very distinct by the great length of the basal joint of the antenne.

* Judging from a difficult examination of a carded specimen.

f+ The great majority of the new species here described are only represented by single specimens, and as

these are carded, they are, though in beautiful condition, somewhat unfit for the careful examination of several

characters important to the description of new genera and species. Soft-bodied insects like the Capside do not

admit with safety of the operation of floating from the cards to which they are affixed, and I have therefore

been compelled to give the best description possible, which with the figures will, I think, simplify the process

of identification.

two first, Eurotas and Lampethusa, seem to appertain to Reuter’s division Plagiognatharia ;

but the third, Demarata, is distinct from any division which, so for as I know, has been

proposed, and this distinctness is in the aberrant character of the antenne, which, taken

alone, would even almost prevent it being classified in the family Capside.

KUROTAS, gen. nov.

Body somewhat elongately subovate, moderately deflexed, and shining. Head deflexed, compressed, and

tapering before the eyes. Antenne inserted in front of the eyes, with the first joint a little longer than

the head, very thickly incrassated and subnodulose ; second joint about half as long again as the first, its

basal half slender, the apical half nodulosely incrassated ; third joint a little more than half the length of

second, and moderately incrassated ; fourth joint about half the length of second, and robust. Pronotum

somewhat triangular, the base moderately convexly tumid, the anterior margin with a very slender

anterior collar, the basal margin about twice the width of anterior margin. Scutellum triangular,

detached from pronotum, its apex acutely produced and with a transverse basal sulcation. Pronotum

with the lateral margins not dilated, the cuneus elongately triangular. Rostrum about reaching the

intermediate coxe.

EUROTAS.—DEMARATA. 303

widely compressed and dilated; second joint slender, incrassated towards the apex, and subequal in length

to first; third and fourth joints slender, third longer than fourth. Pronotum with a distinct anterior

collar, the posterior margin convex, and twice as broad as the anterior margin, beyond basal half strongly

deflected towards head. Scutellum moderately large and tumid, triangular, and with a faint central

base, third joint ochraceous, darker towards apex, fourth joint dark ochraceous ; \pronotum ochraceous,

with the lateral angles and two large and almost confluent spots on each basal side dark castaneous ;

scutellum pale castaneous, with three small basal dark castaneous spots, and with the margins and central

carination paler; corium aud clavus ochraceous, largely and irregularly spotted with dark castaneous ;

cuneus pale castaneous, the basal angles and apex dark castaneous; membrane pale fuscous, spotted and

marked with greyish. Body beneath imperfectly seen (carded specimen) ; legs castaneous, tibie annulated

with ochraceous.

Long. 44 millim.

Hab. Guatemata, Zapote (Champion).

DEMARATA, gen. nov.

Body subovate, moderately convex, pilose, and punctate above. Head broad, compressed in front of eyes.

Antenne inserted nearer to each other than to eyes; first joint moderately incrassated, shorter than head ;

second joint rather more than twice the length of first, and slightly incrassated at apex; third and fourth

joints as stout as second, third about half as long as second, and longer than third. Pronotum deflected from

about the basal third towards head, with the lateral angles not prominent, but subacute, posterior margin

about twice the width of anterior margin, which is not provided with a collar. Scutellum triangular.

Corium widening towards cuneus, which is subtriangular, the fracture not profound. Membrane con-

siderably longer than the abdomen. Rostrum reaching the intermediate coxe.

1. Demarata villosa, n.sp. (Tab. XXIX. fig. 14.)

Head, pronotum, and scutellum black, the pronotum with the base and lateral angles dark castaneous ;

antenns with the first and second joints ochraceous, the third and fourth fuscous; corium and cuneus

dull castaneous; membrane pale fuscous, the cellular areas sometimes darker. Body beneath (carded

specimen) fuscous ; cox and legs ochraceous, apices of the tarsi fuscous. The body above is covered

with greyish pile, which is less abundant on the head and pronotum.

Long. 33 millim.

SUPPLEMENT.

Since the commencement [in 1880] of the present volume, which is devoted to the

families Pentatomide, Coreide, Lygeide, Pyrrhocoride, and Capside, a large number

of additional specimens, including many new species, have reached the hands of the

Editors from several sources, but principally from Mr. Champion, embracing the results

of his collections made in the State of Panama. It is now proposed, in order to include

the supplementary species of these families in this volume, to enumerate and describe

this fresh material, making such corrections as are necessary in relation to what has.

been already published, and to include the additional localities for the previously

recorded species.

Subfam. CYDNINE (p. 1).

Since writing on the Cydnine Dr. Signoret has published an exhaustive treatise on

the group, and although I submitted most of our specimens to him at the time of

preparing this portion for the press, his further studies have led to greater precision, —

so that some corrections require to be made. His loans from the different continental

museums have resulted in the discovery of many new species, which can now be

added to our fauna.

CYRTOMENUS (p. 2).

Cyrtomenus teter (p. 2).

Cyrtomenus excavatus (p. 8).

Cyrtomenus teter, Sign. Ann. Soc. Ent. Fr. ser. 6, i. p. 197, t. 6 (Cydnides, t. 8) fig. 17.

To the localities given, add :—Guatemata, Purula (Champion).

The examination of a long series of specimens being now possible, it appears that:

the male sex is uniformly of the form described by myself as C. excavatus and the

female of the form figured as C. teter. Dr. Signoret has therefore arrived at the opinion,

with which I heartily agree, that the two are but the sexes of one species, and that the

name C. excavatus naturally sinks as a synonym of C. ¢eter.

Cyrtomenus mirabilis (p. 3).

To the localities given, add :—Panama, Bugaba (Champion).

ONALIPS (p. 4; to follow the genus Syllobus).

Onalips, Signoret, Ann. Soc. Ent. Fr. ser. 6, i. p. 323, t. 10 (Cydnides, t. 6) figg. 48, 44 (1881).

This genus is thus differentiated by the author from Syllobus:—‘ Lobes latéraux.

sans dilatation mais arrondis.” .

HEMIPTERA-HETEROPTERA. 305

Onalips contains, at present, only two described species, one of which inhabits

Colombia, including the State of Panama, and the other Western Tropical Africa.

1. Onalips nigerrimus.

Aithus nigerrimus, Dall. List Hem. i. p. 112. 1*.

SYLLOBUS (p. 3).

Syllobus emarginatus (p. 4).

To the locality given add :—Mexico, Presidio (Forrer).

One example of this rare species is now in our collection. This is remarkable for

its small size (long. 8 millim.), but otherwise is not to be differentiated, at least by

myself, from typical specimens.

HOMALOPORUS.

Homaloporus, Uhler, Bull. U. 8S. Geol. & Geogr. Surv. ii. p. 377 (1877) ; Sign. Ann. Soc. Ent. Fr.

. sér. 6, i. p. 330.

This genus is both Nearctic and Neotropical in its distribution, and Signoret has

enumerated three species.

1. Homaloporus pangziformis.

Homaloporus pangeiformis, Sign. Ann. Soc. Ent. Fr. sér. 6, i. p. 331, t. 11 (Cydnides, t. 7) f. 487.

ZETHUS (p. 4).

This genus, as since defined and described by Signoret, “qui est assez difficile &

définir ” (cf. Ann. Soc. Ent. Fr. sér. 6, i. p. 423), embraces a large number of species

(thirty-four), and is represented in both the Eastern and Western hemispheres.

Signoret has also included in the genus thus two species which I had otherwise

generically treated: Pangewus impuncticollis (p. 7) and Microporus testudinatus (p. 8).

2. Aithus rogenhoferi.

To the localities given, add:—Panama, Bugaba, Volcan de Chiriqui 4000 to 6000

feet (Champion).

Dr. Signoret has separated, under the name of P. confusus, the Mexican and North-

American specimens hitherto considered as representives of P. margo, relying upon

differences of punctuation, particularly upon that of the costal area of the corium. In

typical P. margo this area is almost levigate, while in P. confusus it is thickly punc-

tate; but specimens from the intermediate localities, such as Guatemala, are also

intermediate in this character, and I therefore prefer to let the species (a variable one)

remain as before.

7. Pangeus rugifrons.

Pangeus rufifrons (p. 7).

By a misprint this name appeared as “rujfifrons.” Signoret has since seen Prof.

Uhler’s specimens identified as belonging to this species, and considers them as not

conspecific. The habitat “ North America,” given on Uhler’s authority, must therefore,

on these considerations, be withdrawn.

CYRTASPIS (p. 12).

2. Cyrtaspis trinotata, n. sp. (Tab. XXX. fig. 10.)

Black, shining, with three large dull reddish spots—situate one on the disk of the pronotum at the base, and

two (contiguous) on the disk of the scutellum. Eyes luteous. Body above irregularly and sparsely punc-

tate, the spots levigate. (Underside of the body undescribed, owing to the specimen being carded.)

Long. 2 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

Only one specimen of this very distinct species was captured by Mr. Champion.

ALKINDUS, gen. nov. (To follow Cyrtaspis, p. 12.)

Allied to Thyreocoris, but differing in the shape and size of the head, which is broad (not quite twice as broad

as long), convexly lunate, the anterior margins somewhat reflexed and coarsely punctate, and the central

lobe just reaching the anterior margin. .

This genus, by the shape of the head, has a relationship to the subfam. Plataspine,

which as yet is without a recorded American representative; but the general structure

shows the close connection of Alkindus with Thyreocoris.

1. Alkindus atratus, n. sp. (Tab. XXX. fig. 2.)

Black, shining; eyes paler; antenne and tarsi castaneous. Body convex, robust. Head with the frontal

margin widely, thickly, and coarsely punctate. Pronotum foveate at base near each lateral angle, the

lateral margins broadly and coarsely punctate, the disk sparingly and finely punctate. Scutellum not quite

reaching the apex of the abdomen, sparingly and finely punctate, more coarsely and thickly punctate

towards the lateral margins. (Body beneath undescribed, owing to specimens being carded.)

Long. 5 to 53 millim.

Hab. Panama, Tolé (Champion).

Two specimens, both carded, are all I have seen of this species, and these apparently

represent the sexes. The female thus appears to be smaller than the male. The

scutellum of the former does not quite so nearly reach the apex of the abdomen.

CHLENOOCORIS. (To precede the Scutellerine, p. 12.)

Chlenocoris, Burmeister, Handb. ii. 1, p. 383 (1835); Germar, Zeitschr. 1, i. p. 22 (1889) ; Dallas,

List Hem. i. p. 61 (1851).

According to our present knowledge this is a purely Neotropical genus. It has not

hitherto been recorded so far north as our region, whence we have now received three

species, and doubtless others remain to be discovered.

The hemispherical body and long, narrowed, pointed head, considerably narrower

310 SUPPLEMENT.

than the anterior margin of the pronotum, will effectually distinguish Chlenocoris from

the other genera here enumerated.

Hab. Nicaracua, Chontales (coll. Dist.); Panama, Bugaba, Volcan de Chiriqui 2500

The figures given by Herrich-Schiffer of this species and of C. ¢mpressus, Fabr. (of

which I possess an example from Colombia), are not sufficiently dark in coloration.

C. impressus can be distinguished from C. cesus by its somewhat larger size, the sub-

prominent pronotal angles, and, according to the figure referred to, by the different

colour of the antenne.

2. Chlznocoris dissimilis, n. sp. (Tab. XXX. fig. 3.)

Shining black ; eyes luteous; antenne castaneous. (Underside of the body undescribed, owing to specimens

being carded.) Body very convex and gibbous, but oblong (by which last character C. dissimilis differs from

all other described species of the genus). Very obscurely, sparingly, and finely punctate; the anterior

lateral angles of the pronotum subprominent and rounded. Besides being more oblong, C. dissimilis is also

more gibbous than other previously described species of the genus.

Long. 5 millim.

Hab. Nicaragua, Chontales (Janson); Panama, Volcan de Chiriqui 2500 to 4000 feet

8. Chlznocoris compressus, n. sp. (Tab. XXX. fig. 11.)

Allied to C. dissimilis, but differing in the very much narrower and more compressed body ; pronotum not

laterally emarginate as in C. dissimilis, not wider than the eyes at apex. Body above shining black, with

’ some very obscure chocolate reflections; eyes luteous.

Long. 4 millim.

ACHATES. (To precede the genus Orsilochus, p. 16.)

Achates, Stal, Ofv. Vet.-Ak. Forh. 1867, p. 492.

This genus is confined to the Nearctic and Neotropical regions ; three species have

been enumerated by Stal (En. Hem.i.p.9), and a fourth is now added as belonging to it.

1. Achates ramosus, n. sp. (Tab. XXX. fig. 4.)

Ochraceous, an oblique sanguineous abbreviated fascia near each lateral margin of the pronotum, a central

longitudinal fascia to the head and four fasciz to the pronotum (the two central abbreviated and straight,

the other two longer, irregular, and curved), chocolate-brown. Scutellum with some dark longitudinal

fasciee and the apical third and two central wedge-shaped fasciee chocolate-brown. Connexivum ochraceous,

Body beneath and legs ochraceous; the lateral areas of the sternum, the apex of the abdomen, and the

apices of the tibie and the tarsi brownish. Eyes and antenne (the basal joint excepted) fuscous. Antenne

with the third joint longer than the second; fourth and fifth joints longest and subequal in length.

Rostrum reaching the posterior coxe. The head is coarsely punctate at the area of the central lobe and

behind the eyes; pronotum and scutellum coarsely punctate.

Long. 10 millim., lat. pronot. angl. 6 millim.

Hab. Guatemata, San Juan in Vera Paz (Champion).

mann), ‘Tepetlapa in Guerrero (H. H. Smith).

4, Orsilochus (?) diversus, n. sp. (Tab. XXX. fig. 12.)

Reddish-ochraceous ; head with the margins of the central lobe distinctly darker ; pronotum with reticulated

fuscous linear markings ; scutellum crossed by two much waved and sinuated fascie outwardly margined

with fuscous, the first of which crosses at the base, and the second on the posterior portion of the disk,

and disconnected at the centre, two similarly margined spots at the apex; legs ochraceous, tarsi fuscous ;

antenne black, the basal joint reddish-ochraceous. Antenne with the second and third joints short and

subequal in length ; fourth and fifth joints the longest, subequal in length and deeply sulcated. Head

very coarsely punctate at the margins of the central and lateral lobes ; pronotum sparingly and coarsely

punctate, except at the anterior and lateral margins, where the punctures are much more numerous;

scutellum with a distinct convex incision near the base, and coarsely but sparingly punctate.

Long. 9 millim.

Hab. Guatemata, San Geronimo (Champion).

The structure of the antenne, in connection with the very distinct basal impression

to the scutellum, renders this species very distinct from the other members of the genus

here enumerated, even if it really belongs to Orsilochus, or does not, rather, in itself

exhibit the characters of an undescribed genus. One specimen only, and that a carded

one, does not give facility for generic diagnosis, and therefore I have placed it pro-

visionally as above.

AGONOSOMA. (To follow the genus Dystus, p. 18.)

Agonosoma, Laporte, Ess. Hem. p. 69 (1832); Dallas, List Hem. i. p. 5 (1851) ; Stal, Ofv. Vet.-

Ak. Forh. 1867, p. 494.

This genus is allied to Ziridates, which in this publication immediately follows it,

and it can at once be distinguished from that genus by the shape of the odoriferous

apertures, which are somewhat long and moderately curved, whilst in Tiridates they are

short and straight.

This Neotropical genus contains two species, one of which is of an exceedingly protean

character.

This distinct genus, which can be readily distinguished from any other belonging to

the Scutellerine known to our fauna, by the elongated and depressed head, contains

three species, one of which is now for the first time described. The other two also

belong to the Neotropical region, but doubtless others remain to be discovered.

TYNACANTHA (p. 42).

The single species I included in Tynacantha belongs to the following genus, Suppu-

part of our region.

1. Tynacantha splendens, n. sp. (Tab. XXIX. fig. 15.)

Body above metallic purplish, with green reflexions particularly on the head and anterior portion of the

pronotum ; lateral margins of the pronotum, apex of the scutellum, body beneath, and legs luteous ;

the pronotum sometimes distinctly produced, the anterior pronotal lateral margins

denticulated, and the second joint of the antenne distinctly longer than the third;

other characters as in Tynacantha.

The late Dr. Stal, who correctly diagnosed the genus Zynacantha (Ofv. Vet.-Ak.

Forh. 1867, p. 497), certainly included in the enumeration of its species at least one

which differs in the above characteristics, and which, following him, I thus classified

in this work. I now propose the above genus to contain that and another new species

which is here described.

angulated and slightly elevated plate between the posterior legs; abdomen with an obtuse basal spine

and a central longitudinal sulcation.

Allied to Cataulax, Spin., but differing from that genus as diagnosed by Stal (Ofv.

Vet.-Ak. Forh. 1867, pp. 499, 500) in not having the head “ eque longo ac lato vel

longiore quam inter oculos latiore.”

1. Architas pudens, n. sp. (Tab. XXIX. fig. 20.)

Ochraceous, coarsely and darkly punctate; head with the margins of the central lobe and a submarginal fascia

to the lateral lobes formed of almost confluent brown punctures; eyes fuscous ; ocelli reddish-ochraceous ;

antennz dull ochraceous, first, second, and third joints spotted with fuscous; pronotum and scutellum

somewhat sparingly covered with dark brown punctures; corium similarly darkly punctate, but with

some discal patches of still darker punctures ; membrane fuscous; connexivum with small dark marginal

spots. Body beneath and legs pale reddish-ochraceous, with coarse reddish punctures, the lateral

margins more or less testaceous, the legs spotted with fuscous. Antenne with the second joint slightly

2(a). Dinocoris complanatus, n. sp. (Tab. XXXI. fig. 1.)

Body above-and beneath, antenna, rostrum, and legs castaneous ; eyes dull ochraceous ; bases and apices of

tibiee dull reddish. Head very coarsely punctate and rugulose at base; antenne with the second and

third joints subequal in length, fourth and fifth longest, fourth a little shorter than fifth, which has its

base dull ochraceous ; pronotum very coarsely punctate and slightly rugulose ; scutellum coarsely punctate

and somewhat transversely rugulose; corium thickly and more finely punctate; membrane with the apex

paler and extending beyond apex of abdomen; rostrum extending to the penultimate abdominal

segment.

Long. 12 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

This species is allied to D. piceus, Palis.-Beauv., but differs by its less convex and

more flattened upper surface, the different relative lengths of the second and third

joints of the antenne, &c.

PRIAPISMUS, gen. nov. (To follow the genus Dinocoris, p. 47.)

Allied to Dinocoris, but differing in not having the abdomen beneath provided with

a distinct longitudinal furrow, and by the lateral margins of the pronotum being more

or less convex and slightly recurved; scutellum with the apex rounded; membrane

extending to, but not prominently passing, the apex of the abdomen.

I have been compelled to propose this genus for the reception of two species, both

from the State of Panama. Besides the above differential characters, Priapismus

differs from Dinocoris by the smaller size of its species.

1. Priapismus foveatus, n. sp. (Tab. XXXI. fig. 2.)

Castaneous, varying in hue; eyes paler; antennz with the basal third of apical joint ochraceous. Antenne

with the first and second joints shortest and subequal in length, third and fourth longer, subequal in

length, but shorter than the fifth. Pronotum with a somewhat indistinct transverse impression on disk,

on each side of which is a foveate impression near each lateral margin; pronotum and scutellum some-

HEMIPTERA-HETEROPTERA. ~ 325

what coarsely punctate, the last with a small foveate spot at each basal angle; corium more thickly and

finely punctate; rostrum about reaching the penultimate segment of the abdomen.

Long. 9 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion).

2. Priapismus maculatus, n. sp. (Tab. XXXI. fig. 3.)

Ochraceous, much suffused and mottled with black punctures, which are generally situate in confluent patches ;

pronotum with two black spots at lateral margins, one at posterior angle, the other near anterior angle ;

antenne suffused with blackish, the bases of the fourth and fifth joints ochraceous; legs spotted with

black ; connexivum alternately black and ochraceous. Head with the lateral lobes coarsely punctate and

finely rugulose, pronotum and gcutellum sparingly but very coarsely punctate; corium somewhat more

thickly and finely punctate ; antenne with the second joint about as long as or very slightly longer

than the first, third and fourth joints longer and subequal in length, but shorter than the fifth.

Long. 7-9 millim.

Hab. Panama, Volcan de Chiriqui 4500 to 6000 feet, Bugaba (Champion).

In addition to the very different coloration, this species has the lateral margins of

the pronotum rather more convex than in P. foveatus. '

BOTERUS, gen. nov.

Head a little longer than broad; eyes moderately exserted, well separated from the anterior margin of the

pronotum ; lateral margins notched, or obscurely and obtusely spined in front of the eyes; the lateral

lobes reflexed at the margins and united together considerably in front of the central lobe; antennze with

the first and second joints subequal in length. Pronotum about twice as “broad at the base as long;

lateral margins straight or slightly sinuate, and moderately reflexed ; lateral angles rounded ; anterior

angles subacute. Corium with the lateral margins ampliated and convex, the membrane well

developed. Scutellum extending a little beyond the anterior angle of the corium, somewhat broad,

narrowed towards the apex, which is angularly rounded. Rostrum almost reaching the apex of the

abdomen.

The length of the rostrum, the ampliated and convex margins of the corium, and

the exserted eyes well separated from the anterior margin of the pronotum are the

most distinguishing points of this genus.

1. Boterus guatemalensis, n. sp. (Tab. XXX. fig. 17.)

Dark ochraceous, shaded with piceous, coarsely and darkly punctate. Head almost piceous excepting at the

lateral margins, antenne brownish-ochraceous; pronotum considerably shaded with piceous ; scutellum

prominently piceous at the lateral margins and with two small-piceous spots on the apical margin; corium

much suffused with piceous, excepting at the extreme lateral margin, the membrane pitchy. Body

beneath piceous ; underside of the head, rostrum, and legs brownish-ochraceous or dull castaneous; legs

spotted with piceous. Antenne with the first and second joints subequal in length ; third joint very

slightly shorter than the fourth. Head somewhat thickly punctate, excepting at the lateral margins ;

pronotum, ‘scutellum, and corium irregularly and coarsely punctate, the extreme lateral margins of the

pronotum and the corium impunctate.

Long. 13 millim.

Hab. Guatemata, Capetillo (Rodriguez).

326 SUPPLEMENT.

MATHIOLUS, gen. nov.

Body subovate, flattened. Head with the lateral lobes meeting in front of the central lobe, the margins

slightly reflexed, obtusely and obscurely toothed on each side in front of the eyes. Pronotum much

narrower in front than at base. Scutellum attenuated posteriorly. Membrane not quite reaching apex

of abdomen in male, rudimentary and scarcely extending beyond the corium in the female. Rostrum

about reaching the posterior coxe. Antenne five-jointed.

This genus is remarkable for the structural differences between the two sexes, a very

unusual circumstance in the Pentatomide ; the female also in the typical example is

much larger in size than the male.

1. Mathiolus generatus, n. sp. (Tab. XXXI. figg. 43,52.)

Dark castaneous and rugosely punctate above; legs and rostrum much paler in hue. Antenne with the first

and second joints shortest and subequal in length, third and fifth joints subequal in length, a little longer

than the fourth joint.

Male with the membrane short, not quite covering the apex of abdomen, membranal inner margins straight

and sometimes not quite meeting.

Female with the membrane rudimentary, only extending beyond the inner angle of the corium, and leaving

the last three segments of the abdomen exposed.

Long. ¢ 84 millim.; 2 10 millim.

Hab. Guatemata, Cerro Zunil (Champion).

Four males and one female of this very interesting hemipteron were captured by

Mr. Champion. The examples of the males are quite constant in size, and we may

presume that the females are also invariably larger.

6. Brochymena aculeata, n. sp. (Tab. XXXI. fig. 6.)

Closely allied in appearance to B. hadula, St&l, but differing by having the lateral lobes of the head distinctly

longer than the central lobe; the spine above the antenniferous tubercles distinctly longer and much more

acute; the spines on the lateral margins of the pronotum much longer and more prominent ; and in having

the third joint of the antenne much longer than the second joint. The antenne are also uniformly dark

Euschistus spurculus (p. 59).

In his “‘ Enumeratio Hemipterorum,” but not in his original description (Stett. ent.

332 SUPPLEMENT.

Dichelops is closely allied to Euschistus, but differs in having the lateral lobes of the

head much longer than the central lobe and spinously produced. :

The genus is a purely Neotropical one, and six species have been previously enume-

rated. Another species, captured on the Volcan de Chiriqui in Panama by Mr. Cham-

pion, is here added.

1. Dichelops bicolor, n. sp. (Tab. XXXI. fig. 12.)

Body above purplish-brown ; apices of pronotal angles infuscated ; connexivum ochraceous ; antenne reddish,

. with the apical joint fuscous, its base luteous. Body beneath ochraceous, thickly covered with fuscous

punctures, the lateral margins of the abdomen broadly ochraceous ; legs reddish, finely spotted with

fuscous. Head coarsely punctate; antenne with the second and third joints subequal in length, fourth

and fifth joints longest, and also subequal in length. Pronotum and scutellum coarsely punctate; pronotal

more finely punctate.

Long. 14 millim.

Hab. Panama, Volcan de Chiriqui 3000 feet (Champion).

This appears to be the first time that this insect has been properly localized,

“America” being the only habitat previously given. It is probably a scarce species,

as we possess only one specimen from each of the above-mentioned localities.

CHLOROCORIS (p. 67).

Chlorocoris atrispinus (p. 67).

To the localities given, add :—Mexico, Atoyac in Vera Cruz, Teapa in Tabasco

(H. H. Smith), Jalapa (Hoge); Panama, Bugaba, David, Caldera (Champion).

Chlorocoris rufispinus (p. 68).

To the localities given, add :—-MeExico, Tepic (Schumann).

Chlorocoris rubescens (p. 68) (part.).

I was formerly of the opinion that the C. rufopictus, Walk., was synonymous with

the same author's C. rubescens; but with additional specimens collected in Mexico by

Mr. H. H. Smith (Walker’s solitary type-specimens being the only ones previously

known), I find that the pronotal differences are constant, and that the two forms must

be treated as distinct species. In fresh specimens the colour is also green and not

ochraceous. The true C. rubescens is properly figured (Tab. VI. fig. 20).

To the localities given, add :—Mexico, Omilteme in Guerrero (H. H. Smith), Jalapa

(£69e).

HEMIPTERA-HETEROPTERA. 335

Chlorocoris championi (p. 69).

To the localities given, add :—GuateMaLa, Cerro Zunil (Champion).

Since writing the description of this species, we have received a good series of speci-

mens from Mr. Champion, which show that it is of a protean character so far as colour

is concerned, and two varieties, in addition to the typical form described and figured,

may be enumerated.

Var. a. The green ground-colour much broken up and mottled with ochraceous.

Hab. Guaremava, Panima and Sabo in Vera Paz, Cerro Zunil (Champion).

Var. 6. Ground-colour uniform brownish-ochraceous, not green.

Hab. Guatemata, San Gerdénimo, Cerro Zunil, Sabo in Vera Paz (Champion).

Chlorocoris irroratus (p. 69).

To the locality Mexico, add : —Orizaba (H. H. Smith & F. D. G.).

One specimen only of this species is contained in our collection.

9. Chlorocoris usitatus, n. sp. (Tab. XXX. fig. 20.)

Ochraceous, apical area of the corium and the membrane pale greenish; body beneath and legs ochraceous.

Antenne reddish-ochraceous, extreme apices of the joints fuscous, second and third joints subequal in

length, a little shorter than the fourth (fifth joint mutilated) ; eyes fuscous; head and anterior portion of

pronotum much depressed anteriorly ; pronotum very coarsely punctate and rugulose, the lateral margins

finely serrated and narrowly reddish, the lateral angles moderately produced and obtusely acute; corium

coarsely punctate, a small levigate purplish spot on disk, and the base of lateral margin narrowly reddish ;

scutellum coarsely punctate and rugulose; connexivum greenish, its outer margin narrowly reddish, and

with a series of small fuscous spots at the segmental incisures.

Long. 16-17 millim., lat. pronot. angl. 10 millim.

Hab. Guatemaa, Mirandilla, Volcan de Agua 8500 to 10,500 feet (Champion).

Mr. Champion, who captured these specimens, and has since seen them in our

collection, informs us that they are, in a fresh condition, green, and that the ochraceous

hue is due to discoloration. This caution should, no doubt, be extended to other species

of the genus, which are necessarily described from cabinet and dried specimens.

10. Chlorocoris hebetatus. (Tab. XXXI. fig. 16.)

Pale green, margins of the head, lateral margins of the pronotum, and base of lateral margins of corium

narrowly luteous ; eyes brownish-ochraceous; a central narrow longitudinal levigate line extending along

the pronotum and scutellum, and becoming luteous posteriorly. Body beneath and legs greenish-

ochraceous. Antenne reddish-(the fourth and fifth joints mutilated). The head is somewhat coarsely

and sparsely punctate ; the second joint of the antennz is slightly shorter than the third ; the pronotum

is coarsely punctate and rugulose posteriorly, the lateral margins are finely serrate, and the lateral angles

are obtusely prominent; the scutellum is coarsely punctate and rugulose ; the corium is thickly but more

finely punctate. Membrane pale greenish.

Long. 15 millim., lat. pronot. angl. 9 millim.

(Champion).

3 (a). Arocera schumanni, n. sp. (Tab. XXXI. fig. 17.)

Closely allied in general appearance to A. apta, Walk., but differing by the relative lengths of the joints of

the antenne—the third joint in A. schumanni is about one third longer than the second, but in

A, apta it is more than twice as long; the antenne in the last-named species are also much more slender

than in the insect here described. The following colour-differences are also observable :—the transverse

black fascia to the corium is always sinuately notched on its posterior margin; the black lateral sternal

spots in A, apta are absent in A. schumanni; and in the last-named species the apices of the femora are

less broadly black, but the rostrum is almost wholly black, excepting at base.

HEMIPTERA-HETEROPTERA. 337

5 (a). Arocera altivola, n. sp. (Tab. XXXI. fig. 18.)

Allied to A. affinis, Dist., but with different surface-markings, which consist of small black rounded spots,

situate two on disk of pronotum, one at each basal angle of the scutellum, two before the apex of

scutellum, which is also black, and one on the disk of each corium; a large black spot on the margin

of the corium, parallel with the smaller discal spot. This species also differs by having the lateral lobes

of the head distinctly longer than the central lobe.

Long. 12 millim.

lateral margins, a rounded spot at each posterior lateral angle, and two large discal spots resting on

posterior margin more or less black; scutellum with two large spots at base and two large spots near

apex more or less black; corium with irregular black markings; membrane black, the apex greyish-

white. Body beneath reddish-ochraceous, sternal and abdominal segmental margins black ; legs reddish,

much suffused with black ; rostrum pitchy. The body is somewhat short and broad; antenne with the

second joint slightly shorter than the third, which is also a little shorter than the fourth, fourth and fifth

almost subequal in length, or the fourth a little longer than the fifth.

Long. 10 millim.

Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion).

large spots at base of scutellum and two contiguous, near apex of same, a broad irregular transverse

fascia to corium, and the membrane (excluding apex) black. Body beneath ochraceous ; rostrum, legs,

sternum, a double series of spots on lateral margins, and a central series of transverse spots to abdomen,

black. (Antennee mutilated.)

Long. 12 millim.

Hab. Mexico, Jalapa (M. Trujillo).

Allied to A. patibulata, Dist., from Costa Rica, and possibly a varietal form of that

species; but the colour-markings are very distinct, and the difficulties in the study of

the genus would not be lessened by placing these insects under one name, at least

without more specimens and some connecting links. The antenne might give differ-

ential characters, but unfortunately are mutilated in the specimen described.

This genus, which was previously shown to be the largest in the whole Pentatomine,

has again received an extraordinary augmentation, owing to the large amount of

additional material obtained since I Previously enumerated its Central-American

representatives.

Panama appears to be wonderfully rich in species of Edessa, which may be taken

as the most peculiar and representative Neotropical genus of the whole Rhynchota.

346 SUPPLEMENT.

This species is closely allied to E. nigrispina, Dall., and E. bonasia, Stal, both

included in our fauna and figured in this work. From Dallas’s species it may at

once be separated by the shorter. pronotal spines, and by the second joint of the

antenne being subequal to, or a little longer than, the third joint. From EF. donasia

it differs by the shape of the scutellum, which is narrower and resembles that of

EL. nigrispina.

orange-yellow, tarsi brownish-ochraceous ; connexivum obscurely spotted with ochraceous at the segmental

incisures.

Var. Apex of the third joint of the antenne pale castaneous, scutellum more or less ochraceous, corium some-

times obscure castaneous mottled with ochraceous.

The first and second and the third and fourth joints of the antenne are subequal in length; the pronotum is

moderately granulose, the pronotal angles being well produced, broad, spatulate, obsoletely angulated

posteriorly and slightly directed upwardly; the disk of the scutellum, excepting base, is transversely

rugulose; the corium, including clavus, is obscurely punctate; the membrane is bronzy; the posterior

femora are strongly incrassated, with a few tubercles above and strongly spined on each side.

slightly longer than the third; anterior and intermediate femora moderately incrassated, posterior femora

much more strongly incrassated, longitudinally tuberculate, both inwardly and outwardly ; posterior tibie

with a prominent spine beneath near centre.

This genus is allied to Archimerus, from which it is at once differentiated by the

peculiar structure of the antenne, apart from other characters.

I have excluded from the synonymy the identification of Dallas (List Hem. ii.

p. 381. 1, t. 12. f. 3), as the specimens in the British Museum apparently belong to a

darker species with more serrated pronotal margins. Our Panama specimens, however,

agree well with Perty’s figure.

2. Bardistus formidabilis, n. sp. (Tab. XXXIII. fig. 9.)

Pale brownish-ochraceous ; antenna, eyes, lateral and angular margins of the pronotum, three discal longitu-

dinal fasciz to pronotum (of which the central one only reaches the anterior margin), a subquadrate spot at

base of scutellum, a narrow submarginal fascia to corium extending to half its length, femora beneath

(excluding apices), tibie, tarsi, three elongate spots on each side of prosternum, five streaks (four rounded

and one transverse) on mesosternum, a rounded discal spot and a streak at angle of posterior margin of

the metasternum, and the stigmata black. Corium with three oblique fuscous streaks; membrane

bronzy ; connexivum alternately black and dull reddish. The first and second joints of the antenne are

subequal in length, third shortest, fourth longest; the lateral margins of the pronotum are coarsely

crenulate, the lateral angles strongly produced, with a slender apical black spine.

From the examination of a long series of specimens obtained from different localities

in Mexico, in which the shape of the posterior tibiz of both sexes and the colour of the

antenne are of the most variable character, 1am now inclined to consider the A. granu-

losa, Dall., and the A. luctwosa, Stal, as but different forms of one species. The

variation is also of such an intermittent character that I cannot—with the present

abundant material—separate Stal’s form as a constant variety, though we have already

figured it in its typical appearance.

fully developed specimen from Tierra Colorada, and an immature form from Omilteme.

8. Vilga dissimilis, n. sp. (Tab. XXXIII. fig. 21.)

Pale fuscous, posterior margin of pronotum, lateral margins of scutellum, apical joint of antenne, and the

femora dark fuscous ; scutellum reddish-ochraceous, with its apex greyish-white ; connexivum brownish-

ochraceous. The antenne have the three basal joints prominently setose, but the basal joint is not

spinose ; the first and third joints are subequal in length, or the third is a little longer than the first, the

second and fourth joints are almost subequal in length; the pronotum has the lateral margins longly

setose but not spinous, the lateral angles are produced in acute spines, slightly directed forwardly and

upwardly ; the connexivum is distinctly spined at the segmental incisures; the legs are prominently and

Hab. Panama, David (Champion).

This species is somewhat divergent from the typical form of the genus, by the

condition of the basal joint of the antenne, which is setose, not spinous.

4, Vilga divaricata, n. sp. (Tab. XX XIII. fig. 22.)

Brownish-ochraceous ; two central longitudinal lines extending through head and pronotum, basal margin of

pronotum, lateral margins of scutellum, a small excavated spot beneath the inner angle of the corium, and

the segmental incisures to the connexivum dark fuscous ; the tibie are paler in hue, with their bases and

apices darker. ‘The antenne are very obscurely setose, the third joint a little longer than the first and

the fourth a little shorter than the second; the pronotal angles are very acutely produced and directed

forwardly and upwardly; the lateral margins of the connexivum are prominently spined at the

segmental incisures.

Long. 7 millim.

Hab, Panama, Volcan de Chiriqui 3000 feet (Champion).

A single specimen of this insect was obtained by Mr. Champion. It differs principally

from the preceding species by the more prominently and acutely spined lateral angles

of the pronotum, whilst the basal joint of the antenne is even less setose and altogether

non-spinous. It is clear that the diagnosis of St&l’s genus Vilga will have to be less

strictly defined, or more generic division will be necessary.

lateral, and posterior margins of pronotum reddish-ochraceous ; sternum and abdomen beneath ochra-

ceous ; a large subquadrate spot between the eyes, antenna, legs, a large irregular spot on each lateral

area of pro-, meso-, and metasternum extending to base of coxe, rostrum, segmental margins to

abdomen, upper surface of abdomen, and connexivum black or bluish-black. Pronotum very coarsely

punctate, the disk subrugulose, scutellum transversely wrinkled, corium very finely punctate. (Rostrum

apparently mutilated.)

Long. 22 millim.

Hab. Panama, Bugaba (Champion).

By its size and general appearance this species is allied to S. longirostris, Dist., from

which it is separated by the different colour of the abdomen above and of the lateral

margins of the pronotum, and by the different markings to the sternum. By the

colour of the dorsal surface of the abdomen it is allied to S. sumptuosus, Stal, but

here again its much larger size and the colour of the margins of the pronotum will

at once distinguish it.

A single specimen was obtained by Mr. Champion.

This species appears to be better placed in the subgenus Burtinus, Stal, than in the

subgenus Megalotomus, Fieb., where I previously located it (anted, p.158). The length

of the posterior femora places it in Stal’s division, but the antenne are divergent, as in

many specimens the fourth joint is shorter than the second and third together.

In a long series now before me I find the species to be still more variable than I

formerly supposed. In length it varies from 6 to 74 millim.; the pronotum is more

often concolorous than in the typical Guatemalan specimens described; and in some

examples the legs are unicolorous and not speckled with fuscous. By this last

character it approaches the J. spinosus, Say, a Nearctic species.

The specimen described by Stal was in bad condition :—‘ Specimen captum in spiritu

exception, all the specimens examined have the head black, a character not mentioned

by Stal; but as they come from a wide area, extending from Mexico in the north to

Entre Rios in the south, and agree specifically in a perfect manner among themselves

and generally well with Stal’s description of his badly-preserved type, I naturally

refrain from describing another species. Moreover, one of the specimens from Entre

Rios in the Brussels Museum has the head pale castaneous. ‘There is no doubt,

judging from my own experience, that the genus Jalysus is most variable in its species

when the described forms are examined with ample material, and that it at present

exists in some amount of specific uncertainty—another welcome testimony to the truth

of evolutionary principles.

scutellum is also streaked with the same colour; but in a variable species, now studied

by the aid of more than a hundred specimens, colour-varieties are not uncommon.

The specimens from the State of Panama are more obscurely coloured than the

Mexican type of Stal which is here figured (Tab. XVII. fig. 15). A: brevicollis is

scarcely separable, save by size, from the species described by the same author as

A. tullus, and specimens of both have now been received from the State of Panama

and from the same locality. Size, and the brightness of the posterior margin of the

pronotum, can almost alone be used as discriminating characters.

BELONOCHILUS. (To follow the genus Wysius, p. 190.)

Belonochilus, Uhler, Proc. Bost. Soc. Nat. Hist. xiv. p. 104 (1871).

The elongate body and the long head, which with the pronotum forms “a long

triangle,” will almost alone separate this genus. It previously contained but one

IMBRIUS. (To follow the genus Jschnorhynchus, p. 194.)

Imbrius, Stal, En. Hem, iv. p. 124 (1874).

A genus to be distinguished from Jschnorhynchus by the shorter corium, the apical

angles of which do not reach the apex of the abdomen, and by the carinate lateral

margins of the pronotum.

One species only has been described, and this appears to be found commonly in our

fauna.

the apex is also concolorous. The scutellum is either wholly black, marked with

black only, or ochraceous.

We have received numerous examples which appear to agree fairly well with St&l’s

description.

of about equal breadth. Allied to Jmbrius by having the corium shorter than the

abdomen, by the truncate posterior margin of the pronotum, and by the distinctly

carinate lateral margins of the pronotum. The head is a little longer than broad.

(Carded specimens prevent further diagnosis.)

1. Mayana costata, n. sp. (Tab. XXXIV. fig. 13.)

Ochraceous shaded with fuscous; corium with the lateral margins spotted with fuscous ; basal margin and apex

these Panama specimens—of which we have received a fair series—from P. edancalodes,

which has a more northern habitat.

Erlacda, Signoret, Aun. Soc, Ent. Fr. (4), iii. p. 567 (1864) ; Stal, En. Hem. iv. p. 144 (1874),

This genus was founded for the reception of a single Chilian species, and the Mexican

one I here described agrees in all respects with the generic diagnosis, and also in

general form and appearance with the Chilian type, save by the length of the first joint

of the antenne, which in that species scarcely reaches the apex of the head, but

which in the species I now describe passes the apex by quite two-thirds its length.

Although the length of the first joint of the antenne is doubtless a good generic

character in differentiating this difficult group, I have refrained from adding another

genus to those I have already been compelled to propose.

1. Erlacda (?) insititia, n. sp. (Tab. XXXV. fig. 8.)

Black ; apical joint of antenne: (excluding base and apex), intermediate and posterior legs (excluding apices

of femora, bases and apices of tibia, and the apices of the tarsi), basal half of lateral margin of corium

and a spot near apex of same, and a spot at base of lateral margin of membrane pale ochraceous ; anterior

tibiee pale brownish. Membrane black, not reaching the apex of the abdomen. Posterior lobe of the

pronotum and the corium coarsely punctate. Antenne with the second joint slightly longer than the

third, first and fourth joints subequal in length. The head, lateral areas of the pronotum, and anterior

femora are prominently setose; the anterior femora are longitudinally and robustly spined beneath,

Hab. Mexico, Amula in Guerrero (H. H. Smith).

This species, of which we have only received a single example, has the anterior lobe

of the pronotum considerably less globose than in P. globosus.

SISAMNES, gen. nov. (To follow the genus Prytanes.)

Antenne with the joints moderately short and incrassated, second joint slightly longest, and third slightly

shortest. Head about as broad as long, inserted to the eyes. Pronotum with the anterior collar distinct,

the constriction near base, the anterior lobe being thus more than twice the length of the posterior lobe

angles rounded. Scutellum centrally carinate ; corium coarsely punctate, its lateral margins moderately

convex, extending to about two-thirds the length of abdomen; membrane absent. Anterior femora

incrassated, spined beneath.

This genus, like Prytanes, is allied to Carpilis, Stal, the short description of which

agrees with neither of them.

1. Sisamnes contractus, n. sp. (Tab. XXXV. fig. 11.)

Pale brownish-ochraceous; antennz, head, and anterior lobe of pronotum castaneous; exposed apical third of

abdomen piceous. Body beneath castaneous ; legs ochraceous, the femora (excluding apices) castaneous.

which are exposed and moderately prominent. Lostrum with the basal joint a little shorter than the

head, second about equal in length to the first, third as long as second and first together, fourth

very small.

The more or less exposed abdominal margin is a salient feature of this genus.

1. Bathycles maculatus, n. sp. (Tab. XXXV. fig. 12.)

Pitchy-black ; two small spots near claval suture, the base and a large spot near apex of corium ochraceous ;

membrane fuscous; apical joint of the antenne brownish; bases of the femora apparently narrowly

ochraceous (carded specimens). Antenne with the second joint longest, the third a little shorter than the

the apex of the third black.

Long. 34 millim.

Hab. Guaremata, Cubilguitz in Vera Paz (Champion).

We possess a single example of this species, which is structurally somewhat divergent

from the other species described. The head, including the outer margins of the eyes,

is very slightly broader than the anterior margin of the pronotum, and the anterior lobe

of the pronotum is considerably broader than the posterior lobe; the lateral margins

of the anterior lobe are also distinctly convex.

CAENEUS, gen. nov. (To follow the genus Neocattarus, p. 215.)

Body somewhat elongate, tapering towards the apex of the abdomen. Head inserted to the margins of the

eyes, about as long as broad; including margins of eyes about equal in width to the anterior margin of

the pronotum. Antenne with the basal joint short and not passing the apex of the head; apical joint

Jongest. Pronotum with the base broader than, but not twice as wide as, the anterior margin, which is

broadly and coarsely punctate, the lobes bicolorous, the transverse constriction obscure; basal margin

truncate. Scutellum coarsely punctate, with a faint central carination. Clavus and corium lineately

punctate. Anterior femora spined beneath. Rostrum reaching or slightly passing the intermediate coxe ;

the basal joint a little longer than the head.

greyishly pilose ; the posterior pronotal lobe is sparingly but. coarsely punctate.

Long. 3 millim.

Hab. Nicaragua, Chontales (Janson); Panama, Bugaba ( Champion).

We have received a single example from each of the above localities. That from

the State of Panama is figured; the Nicaraguan specimen is rather darker in hue.

HEMIPTERA-HETEROPTERA. 405

SCYTHINUS, gen. nov. (To follow the genus Ceneus.)

Body somewhat elongate, but moderately broad. Antenne with the basal joint very long, considerably passing

the apex of the head; second joint almost as long as the first, a little longer than the third; second and

third joints obscurely hirsute. Head a little longer than broad, distinctly exserted behind eyes, and with

a small rounded protuberance on each side of inner margins of eyes. Pronotum with the base rather more

than twice as broad as the anterior margin, constricted at middle, the posterior lobe punctate, the anterior

margin coarsely punctate. Scutellum without a central carination; clavus and corium coarsely punctate.

Anterior femora unarmed. Rostrum reaching the intermediate coxe, with the basal joint about as long

as the head; second joint about as long as the first (imperfectly seen; carded specimen).

It is somewhat difficult to define the exact position in the Neotropical ‘ Rhyparo-

chromaria’ that this genus should occupy. By the exserted head it would seem to

approach the Ozophora of Uhler, but differs from that genus by the unarmed anterior

femora.

1. Scythinus splendens, n. sp. (Tab. XX XV. fig. 17.)

Head, pronotum, and scutellum reddish-ochraceous. Corium ochraceous, with the apex and a spot near centre

of lateral margin purplish-black. Membrane ochraceous. Antenne with the basal joint reddish-ochra-

ceous ; the second and third joints fuscous; the apical joint stramineous, with its buse and apex very

narrowly fuscous. Body beneath reddish-ochraceous ; rostrum and legs ochraceous.

CLIGENES, gen. nov. (To follow the genus Scythinus.)

Head inserted to the posterior margin of the eyes; antenne with all the joints moderately incrassated, first

joint just passing the apex of the head ; pronotum strongly constricted in the middle, the anterior lobe

broader than the posterior lobe, the basal margin distinctly concave; scutellum moderately large and

without a central carination ; clavus longitudinally punctate ; corium coarsely punctate, broadly truncate

at its inner angles, and from thence somewhat convexly rounded to apices,

The peculiar structure of the corium will serve to distinguish this genus, of which I

am unable to describe the rostrum and under surface, owing to the typical specimen

being carded.

1. Cligenes distinctus, n. sp. (Sab. XXXV. fig. 18.)

Ochraceous ; antennz, anterior lobe of pronotum, and scutellum castaneous ; head, lateral angles of pronotum,

a spot near centre of lateral margins of corium, apex of corium, and membrane blackish; apex of

scutellum ochraceous, preceded by a blackish spot; body beneath blackish or dark castaneous; the legs

ochraceous. The posterior lobe of the pronotum is coarsely punctate, the lateral margins of the corium

PETISSIUS, gen. nov. (To follow the genus Trapezus, p. 217.)

Allied to Trapezonotus and Trapezus; from the first it differs by having the pronotum much broader than

long and the head longer than broad, and from Trapezus by having the head, including the outer margins

of eyes, about equal in width to the anterior margin of the pronotum. From both and from all the

allied genera it is distinguished by the shape of the pronotum, which is much narrower at apex than at

base, with the lateral margins non-ampliated. ‘The first and second joints of the antenne are sparingly

hirsute ; the anterior femora are spinous beneath at apex, and the intermediate and posterior tibie are

longly setose.

1. Petissius assimilandus, n. sp. (Tab. XXXV. fig. 21.)

Head black ; antenne ochraceous, with the apical joint infuscated, second joint slightly longer than the third,

Body above reddish-ochraceous and pilose ; eyes black; scutellum and apical areas of the corium castaneous;

antennee with the basal joint reddish-ochraceous, the remaining joints dull brownish; second joint a

little longer than the third, third and fourth joints subequal in length; memtbrane pale ochraceous; body

beneath reddish-ochraceous, legs pale ochraceous. The lateral’ margins of the pronotum and corinm are

very narrowly pale ochraceous; the pronotum has a transverse impression; the corium is strongly

pilose.

Long. 3 millim.

Hab. GUATEMALA, Paraiso, E] Reposo (Champion) ; Panama, David (Champion).

We have received three (carded) specimens of this species, for which I hesitate to

propose a new genus. It differs from the type of Petisstus by having the head

including the eyes a little narrower than the anterior margin of the pronotum ; the

other characters are, however, generally the same.

EREMOCORIS (p. 218).

2. Eremocoris germanus, n. sp. (Tab. XXXV. fig. 24.)

Head black ; pronotum with the anterior lobe castaneous, with its lateral margins ochraceous, the posterior

lobe of the pronotum, different colour of the antenne, &c.

Two examples.

BALBOA, gen. nov. (To follow the genus Hremocoris, p. 219.)

General characters of Lethewus, Dall., but differing from that genus by having the second joint of the antenne

not longest, but only subequal in length to the fourth; the rostrum has the basal joint as long as the

head and not shorter than the second and third joints. Anterior femora spined beneath. Membrane

with the second, third, and fourth nervures neither united nor forming basal cells. By the last

character Balboa is allied to Cistalia, St&l, but differs by having the basal joint of the antenne

somewhat thickened as in Letheus, as well as by the other characters enumerated above.

1. Balboa variabilis, n. sp. (Tab. XXXV. fig. 25.)

Ochraceous, somewhat thickly and coarsely punctured with brown; apex of third and apical half of fourth

joint of antenne, head, anterior lobe of pronotum, a spot on each side of the clavus near apex, two

Of this very variable species, both in size and colour, we have received a long series ;

it appears to be scarce in Mexico and very plentiful in Guatemala. In some of the

typical forms the anterior lobe of the pronotum is castaneous rather than black.

tibiz and the tarsi more or less infuscated. Antenne with the second joint considerably longer than the

third, which is almost the length of the fourth ; margins of the anterior lobe and the whole basal lobe of

the pronotum and the scutellum thickly and finely punctate; corium sparingly but coarsely punctate ;

membrane pale fuscous.

Long. 53 millim.

Beyond the colour, I can find no sufficient structural character to warrant this form

being described as a distinct species. We have received it much more plentifully than

the typical form here described.

BUBACES, gen. nov. (To follow the genus Dorachosa.)

Head longer than broad, inserted almost to the posterior margin of the eyes. Antenne with the first joint

very long, and passing the apex of the head for half its length. Pronotum as long as broad, nearly

RHAPTUS. (To follow the genus Budbaces.)

Rhaptus, Stal, En. Hem. iv. p. 163 (1874).

This genus, allied to the European Lamprodema, was founded by Stal for the recep-

tion of a Chilian species. We have received a series of specimens from Guatemala

which apparently belong to Rhaptus, and which I have included in it. As in all the

examples of Lamprodema brevicollis in my collection the membrane is rudimentary, a

character not mentioned by Stal in his generic diagnosis, but the anterior femora are

finely spined beneath, a character which separates it from the European genus.

1. Rhaptus collina, n. sp. (Lab. XXXVI. fig. 3.)

Head and pronotum shining black, the lateral angles of the pronotum ochraceous; scutellum and corium black,

very coarsely punctate, lateral margins of the corium ochraceous; membrane rudimentary; apex of

abdomen as seen above castaneous. Body beneath blackish; legs ochraceous, femora (excluding apices)

castaneous. Antenne: with the first and second joints ochraceous, the third and fourth piceous, the apex of

Esuris, Stl, En. Hem. iv. p. 164 (1874).

I place another species in this genus by the characters of the rudimentary membrane,

the setose condition of the body, the obscurely spined anterior incrassated femora, &c.

One species has previously been described, from Rio Janeiro.

1, Hsuris purpurata, n. sp. (Tab. XXXVI. fig. 4.)

Purplish-brown, thickly and greyishly hirsute ; lateral and posterior margins of the pronotum, apical margin

of the corium, body beneath, and legs ochraceous. Antenne with the first and second joints ochraceous,

the third and fourth fuscous ; second, third, and fourth joints almost subequal in length.

Long. 2 millim.

Hab. Guatemata, Paso Antonio (Champion).

A single example.

HEMIPTERA-HETEROPTERA. 411

Subfam. HETEROGASTRINE. (To precede the Fam. Pyrrhocoride, p. 220.)

Heterogastrina, Stal, Ofv. Vet.-Ak. Foérh. 1872, p. 40.

This subfamily contains two Palearctic genera, one of which has been recorded from

North America by Prof. Uhler, one purely Nearctic genus, apparently found in our

fauna, and a genus founded to contain some species from the Philippine Islands.

Doubtless more remain to be discovered in many quarters.

PELIOPELTA.

Peliopelia, Uhler, Check-List Hemipt.-Heteropt. North America, p. 15 (1886).

Helonotus, Uhler, Bull. U.S. Geol. & Geog. Surv. ii. p. 312 (1875) (nomen preocc.).

‘This genus was founded for the reception of a somewhat widely distributed North-

American species. We have received an insect from Mexico and Guatemala which

agrees in all essential respects with the generic diagnosis, and which is therefore now

described as a Peliopelta.

1. Peliopelta tropicalis, n. sp. (Tab. XXXVI. fig. 5.)

Brownish-ochraceous; eyes, margins of the longitudinal carina to scutellum, two spots on apical margin of

corium, and a series of spots to connexivum black. Base of anterior lobe to pronotum, and five narrow

longitudinal fasciz to posterior lobe, and the lateral angles of same, castaneous. Membrane pale greyish

hyaline. Antenne with the two basal joints ochraceous, their apices and the whole of the third and

fourth joints castaneous. Body beneath ochraceous and thickly greyishly pilose; legs ochraceous, the

femora (excluding apices) castaneous, the tibie annulated with black near base and apex. The head,

pronotum, and scutellum are somewhat thickly and coarsely punctate, the corium more finely and sparingly

punctate.

Long. 5 millim.

Hab. Mexico, Amula in Guerrero (#1. H. Smith); Guatemaua, Quiché Mts.

(Champion).

A single example was sent us by Mr. Champion and two by Mr. Smith, which are.

very distinct from the description given by Prof. Uhler of his P. abbreviatus, though allied

by the markings of the tibia. The specimens being carded, I am unable to describe

the under surface.

LARGUS (p. 220).

Largus cinctus (p. 223).

To the localities given, add :—Mexico, Presidio de Mazatlan in Sinaloa, and Ventanas

in Durango (Forrer), Morelia (F. D. G.), Cuernavaca in Morelos (H. H. Smith),

Atoyac (Schumann), Orizaba (H. H. Smith & F. D. G.), Amula, Chilpancingo, La Venta,

Omilteme and Xucumanatlan, all in Guerrero (H. H. Smith), Temax in North Yucatan

(Gaumer); Brrrish Honpuras, R. Sarstoon (Blancaneaux) ; Guatemata, Chacoj, Senahu,

and Teleman in Vera Paz, Paraiso (Champion).

I have previously expressed my reasons for considering the ZL. varians, Stal, as

representing simply a variety of Z. cinctus, H.-S. I have now a still larger series of

Mexican specimens before me, which causes a strong doubt whether even the

L. longulus, Stal (p. 223), can be considered a distinct species. To separate these

named forms is simply an operation of sorting specimens, and even this breaks down

when a long series is examined. Had that most careful worker and systematist Stal

possessed the material that we have amassed, he would doubtless have pursued a more

synthetic course. The species varies greatly in size, from 9 to 16 millim., the breadth

of the body is also a most variable character.

FIBRENUS (p. 224).

Fibrenus globicollis (p. 224).

To the localities given, add:—Panama, Volcan de Chiriqui 2500 to 4000 feet

(Champion).

Vera Cruz, Amula, Chilpancingo, and Xucumanatlan in Guerrero (H. H. Smith).

HEMIPTERA-HETEROPTERA. 413

Stenomacra cliens (p. 226).

Stenomacra sallei, Fallou, Rev. d’Entomol. x. p. 8.

M. Fallou has kindly forwarded me a Mexican specimen which he had described as

a new species under the name of S. sad/et; but this proves to be identical with S. cliens,

Stal, as also recently observed by Dr. Bergroth (Rev. d’Entomol. xi. p. 262).

PHLAAX, gen. nov. (To precede the genus Arhaphe, p. 226.)

Head very broad, immersed to the posterior margins of the eyes, obscurely angulated anteriorly. Antenne inserted

at nearer apex of head than eyes; basal joint incrassated, about or scarcely reaching apex of head, second

joint longest, its apex slightly incrassated, third Joint more or less distinctly incrassated at apex, and shorter

than the fourth, which is thickened. Pronotum long, very strongly constricted at about centre, the anterior

lobe moderately globose, the posterior lobe angularly depressed from its disk to the median constriction :

anterior lobe sublevigate, excepting near anterior margin, posterior lobe thickly and coarsely punctate.

Scutellum somewhat centrally gibbous. Abdomen and corium very strongly concavely sinuate to a little

beyond centre, where they are widened, and the abdomen is convexly rounded to apex ; the membrane docs

not cover the lateral abdominal margins. The anterior femora are very strongly incrassated, and have one or

two long spines beneath near apex ; the posterior legs are long. Rostrum with the basal joint not quite

reaching the latitude of the eyes, second joint slightly passing the base of the head, apical joint reaching

or slightly passing the anterior coxe, second and fourth joints about subequal in length, and a little

longer than the third joint. Ocelli absent.

I place this remarkable genus near Arhaphe, with which, however, it has little in

common.

1. Pheeax formicarius, n.sp. (Tab. XXXVI. fig. 6.)

Black ; corium with a greyish-white spot at about centre of lateral margin and another at the apex, these spots

being margined with intense black, a pale spot on connexivum near apex of corium. Antenne with the

apex of the first joint and the base of the second pale ochraceous ; intermediate and posterior femora annu-

lated with greyish-white near base; tarsi ochraceous.

Long. 52 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 6000 feet (Champion).

Four examples.

2. Pheax balteatus, n. sp. (Tab. XXXVI. fig. 7.)

Allied to the preceding species, P. formicarius, but smaller, and with the first and second joints of the antenne

(excluding apex of second) ochraceous ; anterior femora and tibiz brownish-oehraceous, basal annulation

to intermediate and posterior femora small, obscure, and ochraceous, pale spots to corium smaller and

more obscure, and with a transverse greyish-white fascia across the base of the membrane. The anterior

lobe of the pronotum is also less punctate at its anterior margin.

Long. 4 millim.

Hab. Panama, Bugaba (Champion).

Two examples.

PYRRHOCORIS (p. 228).

Pyrrhocoris apterus (p. 228).

This species was included in our fauna on the authority of several specimens labelled

“Costa Rica—Van Patten.” We have, however, received no further confirmation of its

presence in Central America from any other of the collections subsequently received.

DYSDERCUS (p. 229).

Dysdereus mimus (p. 229).

To the localities given, add:—Mextico, Ciudad and Milpas in Durango (Forrer),

and Tierra Colorada in Guerrero, Teapa in Tabasco (7. H. Smith), Temax in North

Yucatan (Gaumer); GuatemaLa, Purula (Champion) ; Panama, Bugaba (Champion).

In examining a very long series of this species, I have found some dark specimens

which can only be separated from D. flavo-limbatus, Stal (p. 230), by their much smaller

size. It is probable that they all really belong to one species, and possible that

D. albidiventris, Stal (p. 229), is still another varietal form of it. Had the wealth of

material now before me been available when I wrote in 1883, I should have greatly

hesitated in following Stal in this matter, and recording three distinct species.

Dysdercus albidiventris (p. 229).

To the localities given, add:—MeExico, Jalapa (Hége), San Lorenzo near Cordova

(M. Trujillo), Frontera and Teapa in Tabasco (H. H. Smith); Panama, Volcan de

Dysdercus ruficollis (p. 233).

To the localities given, add:—Guatemaua, Teleman in Vera Paz (Champion) ;

PaNnaMA, Bugaba (Champion).

We have now received a variety very similar to that figured by Hahn (Wanz. Ins.

ii. fig. 123), with the exception that the scutellum, clavus (wholly or part), and the

basal half of the pronotum are black, as well as the posterior halfof the corium. This

variety was found by Mr. Champion at Bugaba and on the Volcan de Chiriqui. In

my own collection there are examples of it from Colombia and Brazil.

MIRIS (p. 236).

Miris guatemalanus (p. 236).

2(a). Miris panamensis, n. sp. (Tab. XXXVI. fig. 8.)

Allied to M. guatemalanus, but larger, the pronotum and scutellum more sparingly and finely punctate ; apex

of the clavus fuscous, a curved inner fuscous streak to corium terminating in a darker fuscous spot near

inner basal angle of cuneus; posterior femora castaneous; apex of the head more produced than in

M. guatemalanus.

Long. 11-12 millim.

Hab. Panama, Volcan de Chiriqui 8000 feet (Champion).

Mr. Champion took two examples of this species, and both at the above altitude.

EIONEUS, gen. nov. (To follow the genus Miris, p. 237.)

Head long and moderately ascending in front, the apex subacutely produced, the lateral margin between base

of antennez and apex prominently toothed, the basal half with a central narrow longitudinal sulcation ;

antenn# with the basal joint about as long as the head and pronotum together, incrassated and strongly

setose, second joint longer than the first, but shorter than the third. Pronotum much longer than broad,

the anterior margin concavely sinuate, the posterior margin strongly concavely sinuate before the base of

the scutellum, the anterior area with two fine transverse constrictions. Scutellum with the base convex, a

very large and profound fovea at each basal angle, followed by a fine but distinct transverse constriction,

the apex nodulose. Posterior legs very long, the femora almost reaching the apex of the membrane,

tibie long and strongly setose. (Under surface not described owing to specimens being carded.)

The remarkable structure of the scutellum renders this genus very distinct.

1. Hioneus bilineatus, n. sp. (Tab. XXXVI. fig. 9.)

Pale ochraceous; eyes black; apex of head and the basal sulcation infuscated; two central indistinct fuscous

lines extending through pronotum and scutellum ; antennee with the basal joint dark ochraceous and very

strongly setose ; posterior tibiae and base of posterior tarsi very bright castaneous, apices of all the tibiz

black.

Long. 7-8 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); GuarEMata, San Gerdénimo and

Senahu in Vera Paz (Champion); Honpuras, Ruatan Island (Gaumer).

Head, pronotum, and scutellum ochraceous; corium dark castaneous speckled with ochraceous ; basal margin

of cuneus and the membrane brownish ochraceous; body beneath and legs ochraceous. (Antenne

mutilated, the second joint dark castaneous.)

Long. 7 millim.

Hab. Gvatema.a, San Gerénimo (Champion).

A single specimen, in poor condition, constitutes my sole knowledge of this species.

It is, however, sufficiently distinct from M. argillaceus to make its description necessary.

* HEMIPTERA-HETEROPTERA. A417

Besides its different colour, it is separated from that species by having the base of the

pronotum more concave and the base of the scutellum more foveate.

XENETUS (p. 239).

Prof. Uhler (Ent. Amer. iii. p. 151) has stated that my genus Xenetus ‘* will no

doubt prove upon actual comparison of the types to be the same” as Hucerocoris,

Westw. I can scarcely follow this opinion, as the two genera have not only been fully

described, but the types of both have been also figured. The structure of the antenne

alone is sufficient to prevent any confusion.

“‘ Antenne corpore toto fere triplo longiores.” « Antenne not quite so long as the body.”

‘ Articulis tribus primis longitudine fere zequali- “ First joint about as long as the head or longer,

ZOSIPPUS (p. 241).

2. Zosippus foedus, n. sp. (Tab. XXXVI. fig. 11.)

Black ; eyes, basal joint of antenne and bases of second and third joints, a short transverse fascia near centre

of corium, apices of the tibia, posterior margins of the pro- and mesosternum, and a spot near base of

abdomen, ochraceous. The body above is very sparingly greyishly pilose.

Long. 4 millim.

Hab. Panama, Bugaba (Champion).

This species differs from Z. inhonestus, Dist., by the much more profound anterior

constriction of the thorax, the more oblique and less conical tubercle to the scutellum,

the less pilose body, absence of the apical pale spot to corium, &c. Mr. Champion

found a single example.

3. Zosippus gibbus, n. sp. (Tab. XXXVI. fig. 12.)

Very pale castaneous; eyes fuscous, the posterior margin of the pronotum very dark violaceous ; tubercle to

the scutellum dark castaneous; antenne with the apices of the second and third joints and the whole of

the fourth joint pale fuscous; corium with a. central transverse curved fascia which is pale ochraceous

anteriorly and dark castaneous posteriorly, and with two pale ochraceous spots near base of membrane ;

cuneus ochraceous, with the basal margin, inner angle, and apex fuscous; base and apex of clavus, a

lateral spot beyond centre of corium and inner apical angle and apex of same violaceous ; femora ochraceous

spotted with castaneous, tibize and tarsi brownish-ochraceous ; membrane brownish-ochraceous. Tubercle

to scutellum large, broad, and upright. (Body beneath imperfectly seen owing to specimens being carded.)

Long. 5 millim.

Hab. Panama, Bugaba (Champion).

This species, of which we have received two examples, is distinguished by the large,

broad, upright tubercle to the scutellum.

HERDONIUS. (To follow the genus Zosippus, p. 241.)

Herdonius, Stal, Rio Jan. Hem. i. p. 55 (1858).

I place the following species in this genus on account of the antenne being as long

as the body, the scutellum possessing an erect spine at the apex, and the abdomen being

constricted, though not “fere petiolatum.” The shape of the head appears different

from the rather meagre description of the same, and the thorax is not “apice

capite multo angustior”; but not having seen a typical specimen, and the general

HEMIPTERA-HETEROPTERA. _ 419

characters agreeing fairly well with Stal’s diagnosis, I have refrained from proposing a

new genus.

Herdonius was founded for the reception of a single species from Riv Janeiro.

1. Herdonius (?) panamensis, n. sp. (Tab. XXXVI. fig. 13.)

Black; corium dark purplish ; head, tibie, and apices of the femora castaneous; antenne ochraceous; margins

of the lateral angles of the pronotum, apical spine to the scutellum, basal margin of corium, and a trans-

verse central fascia to same and the cuneus greyish-white ; membrane dark fuscous, the lateral margins

paler; anterior and intermediate femora longly and thickly setose beneath; pronotum thickly and finely

punctate.

Long. 5 millim.

Hab. Panama, Bugaba (Champion).

A single example in poor condition.

LYGDUS (p. 242).

2. Lygdus mimicus, n.sp. (Tab. XXXVI. fig. 14.)

Body above reddish-ochraceous ; head, antenne, a broad subtriangular fascia to pronotum, scutellum, clavus, a

broad transverse fascia to corium, cuneus, membrane, body beneath, and legs, black; lateral areas of

prosternum, and lateral margins of corium as seen beneath, reddish-ochraceous. The abdomen is convexly

rounded and dilated on each side, the lateral margins of the first, second, and third segments extending a

little beyond the margins of the corium.

Long. 10 millim.

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

This species, of which Mr. Smith sent us a single example, is an extraordinary mimic

of aspecies of the Lygeid genus Oncopeltus. The antenne are less strongly hirsute

than in the other species which I described from the State of Panama.

Another species from Venezuela is contained in my collection *.

p. 68) has recorded his rediscovery of the lost species, Cylapus tenuicornis, described

by Say, and has given an excellent figure of the same. For the reception of this species

Say proposed the generic name Cylapus. From a comparison of Mr. Heidemann’s

figure with those representing species of Stal’s genus Valdasus in this work, Prof. Uhler

(ibid. p. 123) has rightly concluded that the two genera are synonymous, and that,

despite Say’s very meagre diagnosis, the name Cyl/apus must take precedence.

1. Cylapus famularis.

Valdasus famularis, huj. op. p. 243, Tab. XXIV. fig. 7.

Prof. Uhler (Proc. Ent. Soc. Wash. 1891, p. 123) has expressed his opinion that this .

species is really the Cylapus tenuicornis, Say, and that therefore Stal’s species must sink

as asynonym of the same. I was, however, fortunately enabled to figure the type of

C. famularis in this work (Tab. XXIV. fig. 7), and from a comparison of this with

Mr. Heidemann’s figure of the North-American species described by Say, I am unable

to share Prof. Uhler’s opinion. The Mexican species thus appears more elongate and

narrow, and the difference of markings may be seen in the corresponding presence and

absence of the pale marginal spots to the pronotum of C. tenuicornis and the apical

claval spot in C. famularis. The markings of the scutellum, corium, aud cuneus are

also different in the two species.

and coarsely punctate.

Long. 5 millim.

Hab. Panama, Bugaba (Champion).

Allied to C. stygius, Dist., but with the pronotum narrower, and the body much

more elongate; the colour of the legs is also a very distinctive character. We have

only received one specimen.

apex of the second joint luteous; a small spot on each side of clavus near apex and the basal margin of

cuneus pale greyish ; membrane fuscous, with the basal cellular area blackish ; legs pale castaneous, femora

with the base and a subapical annulation luteous, apices of the tarsi luteous.

Long. 4 millim.

Hab. Payama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

This species is allied in general shape and markings to C. rugosus, Dist., but differs

by its smaller size, narrower body, and the non-rugose corium.

‘Two examples,

JOBERTUS, gen. nov. (To follow the genus Cylapus (Valdasus), p. 245.)

Head broad, including the eyes much broader than the anterior margin of the pronotum, transverse, excavated

on each side near the eyes, and vertically deflexed in front of same. Antenne about as long as the body,

the basal joint slightly incrassated and a little shorter than the head, second joint about as long as the third

and fourth joints together. Pronotum subtriangular, with a broad anterior collar or narrow lobe, the

posterior margin convex, and about twice the width of the anterior margin, the lateral angles subpro-

minent, the lateral margins oblique and slightly concave. Scutellum subtriangular, moderately tumid,

and with a central basal excavation. Corium with the lateral margins a little widened posteriorly ;

cuneus very large, about as broad as long; membrane rather small. (Rostrum indescribable owing to the

typical specimen being carded.)

Division CLIVINEMARIA. (To precede the Division Loparia, p. 251.)

Clivinemaria, Reuter, Ofv. Vet.-Ak. Férh. 1875, no. 9, p. 62.

This division, proposed by Dr. Reuter for the reception of a Texan genus and species,

appears to me the most natural position for the following genus. The characters on

which I rely are “caput, pronotum et scutellum dense et longe tomentosa,” and also

the peculiar structure of the pronotum.

RANZOVIUS, gen. nov.

Head, pronotum, and scutellum longly pilose. Head foveate between the eyes. Antenne setose, more than

half the length of the body, the first and second joints strongly incrassated, first joint a little shorter than

the head, second considerably longer than the first, third and fourth joints slender, and together a little

longer than the second joint. Pronotum broader at base than at apex, profoundly foveate on the anterior

area, and causing the anterior margin to be somewhat tumid. Corium sparingly pilose; the cunens a

little longer than broad; posterior tibize longly setose.

1. Ranzovius crinitus, n. sp. (Tab. XXXVI. fig. 20.)

Head, pronotum, and scutellum black, thickly, longly, and more palely pilose; eyes and the first and second

joints of the antenne castaneous, third joint of the last ochraceous, fourth joint pale fuscous; corium pale

castaneous, sparingly greyishly pilose; cuneus dark castancous, its basal, inner, and apical margins

424 SUPPLEMENT.

greyish-white; membrane hyaline, mottled with pale fuscous; femora castaneous, their apices and the

tibice ochraceous; posterior tibia more or less annulated with fuscous; body beneath dark castanecus or

fuscous.

Long. 2 millim.

Hab. Mexico, Orizaba in Vera Cruz, Omilteme in Guerrero (H. H. Smith).

Mr. Smith sent us seven specimens of the above, but these being all carded and more

or less imperfect, has rendered both the generic and specific diagnosis difficult.

| RESTHENIA (p. 251).

Resthenia plagigera (p. 251).

To the localities given, add:—Mextico, Atoyac in Vera Cruz, Teapa in Tabasco

(H. H. Smith); Guatemaua, Cahabon in Vera Paz (Champion). .

8 (a). Resthenia trujilloi, n. sp. (Tab. XXXVI. fig. 21.)

Capsus bicinctus, Walk. Cat. Het. vi. p. 100. 186°.

To the locality given, add :—Mexico, Oaxaca (Sallé), Tepic (Schumann).

The form described by Walker as above only differs from R. ornaticollis by having the

black basal area to the pronotum notched, and not completely divided by ochraceous. I

had omitted to record and identify this description of Walker when I wrote previously,

and have to thank Dr. Bergroth for recently requesting me to do so.

- Resthenia latipennis (p. 253).

Resthenia univittata, huj. op. p. 258.

The examination of a long series of specimens, which were not available when the

_ above species were enumerated, has convinced me that &. univittata is only another

varietal form of BR. latipennis. The colour of the head is inconstant, and varies from

black to ochraceous in specimens from the same locality.

To the localities given, add :—Mextco, Milpas in Durango (Forrer), San Lorenzo near

Cordova (M. Trujillo), Atoyac, Fortin, and Orizaba in Vera Cruz, Rincon, R. Papagaio,

HEMIPTERA-HETEROPTERA. 427

This insect, of which we have received a single specimen only, is allied in general

coloration to the two Nearctic species, L. confluens and L. media (Say), from both of

which, however, it is quite distinct.

428 ; ' SUPPLEMENT.

I had already (p. 263) queried WV. affinis as “‘n. sp. or var.t”, and the subsequent

examination of a long series of specimens has shown me its truly varietal character.

430 SUPPLEMENT.

JACCHINUS, gen. nov. (To follow the genus Garganus, p. 266.)

Head rather longer than broad, with a very faint central linear sulcation ; eyes well separated from the ante-

rior margin of the pronotum ; antenne with the first joint moderately curved and incrassated, and about

as long as the pronotum, second joint nearly twice as long as the first and attenuated at the base, third

joint slightly longer than the first, fourth about half the length of third. Pronotum with the base about

twice the width of the anterior margin, the lateral margins moderately concave. Scutellum gibbous, the

disk tubercularly elevated. Cuneus moderately long. Posterior legs long, the tibie finely setose.

I have been compelled to propose a new genus for the reception of the following

species, as to the proper position for which I am at present very doubtful. The

tubercular scutellum is a salient characteristic, whilst the faintly sulcated head exhibits

a relationship with the genera I have placed at the commencement of the Capside.

As, however, the aim of this work is faunistic rather than classificatory, I have

temporarily placed Jacchinus near Garganus.

1. Jacchinus tabascoensis, n. sp. (Tab. XX XVII. fig. 10.)

Head, pronotum, body beneath, and legs sanguineous; eyes, scutellum, corium, and cuneus black; antenney

castaneous, apex of the first joint and base of the second black, second joint annulated near base with

apex of the second joint of the antenne, apex of the third, and the whole of the fourth joint, posterior

femora (excluding apices), bases of the posterior tibie and the apices of the tarsi black; inner margin of

the legs ochraceous.

_colour-markings as in the other sex, but the corium and scutellum generally less thickly greyishly pilose.

Long. 3 3, 9 2 millim.

Hab. Mexico, Teapa in Tabasco (H. H. Smith); GuateMa.a, near the city, Duefias,

Cerro Zunil, Senahu (Champion) ; Nicaracua, Chontales (Janson).

We have received a long series of specimens of this species, especially from Guate-

mala, but mostly in an immature condition. 1 should have refrained from sexually

differentiating and describing the undeveloped forms of this species, had not Mr.

Champion, their collector, expressed his opinion that they were undoubtedly females. |

A similar instance occurred with a species from Ecuador, which I described under the

name of Calocoris montanus *, but which I have not ventured to sexually diagnose.

Calocoris nigricans (p. 267).

To the locality given, add :—Mexico, Omilteme in Guerrero (H. H. Smith).

In some specimens the cuneus is castaneous in hue.

To the locality previously given?, add:—Norta America, Eastern Massachusetts,

New York, Pennsylvania, Maryland, Ohio, Southern Illinois, Texas !.—Mzexico, Chilpan-

cingo and Tepetlapa in Guerrero (H. H. Smith).

There is scarcely a doubt that the Mexican Capsid I described as above ? is the widely-

distributed North-American species described by Prof. Uhler, though that author has

included my species under the genus Calocoris in his Check-List. It seems that both

Prof. Uhler and myself have committed an oversight.

MEGACCELUM (p. 269).

2. Megacelum (?) sanguinolentum, n. sp. (Tab. XX XVII. fig. 13.)

Very pale ochraceous; scutellum with two black spots near the apex, which is sanguineous; head with a

specimens).

Long. 8 millim.

Hab. Mzxico, Pinos Altos in Chihuahua (Buchan-Hepburn).

We have received two specimens of this species, which I place in the genus Mega-

celum principally on account of the structure of the apex of the scutellum, which is

deflexed and curved downwardly. It is allied to the other species here described,

M. (2) signatum, Dist., by the spots to the scutellum, but differs by the more parallel

lateral margins of the corium, the sanguineous shadings, the colour of the membrane, &c.

Dr. Reuter (Ann. Soc. Ent. Fr. 1892, p. 401), in recording this genus from Venezuela,

remarks as to its position “Genus divisionis Dicypharia nec Phytocoraria!” If the

reference is intended to apply to this publication, where the genus was founded—and

I know of no other—then Dr. Reuter must have hurriedly consulted what I have

written, for the genus was not placed in Phytocoraria, but in a combination of three

of Dr. Reuter’s own divisions (p. 283), taken from his memoir on North-American

Capside, and apparently almost where he now retains it—near his Cydlocoraria.

long-again as the first, broadiy convex outwardly and attenuated at extreme base; third and fourth

joints very slender, third longer than fourth. Pronotum somewhat triangular, coarsely punctate, deflected

towards apex, which possesses a prominent double collar. Scutellum moderately large, triangular.

Corium talc-like, with its lateral margins slightly convex. (Rostrum inaccessible, owing to the typical

specimen being carded.)

I have provisionally placed this genus near Hurotas and Lampethusa, to both of

which it is allied by the strongly dilated antenne. This arrangement, however, is only

one of convenience, as it is not attempted to rigidly classify the Neotropical Capside in

this work, the aim of which is primarily faunistic.

This species is a close mimic of Paracalocoris attenuatus, Dist., and is almost only

distinguished by the widely different structure of the basal joint of the antenne. It

varies in hue, many specimens being much darker than the type here figured.

APPENDIX.

Tus Appendix is chiefly devoted to the descriptions of some genera and species and

the enumeration of others which have either escaped attention or reached us since we

previously worked at the families to which they belong. As far as this work is

concerned we now definitely conclude our enumeration and descriptions of the families

Pentatomide, Coreide, Lygeide, Pyrrhocoride, and Capside of Central America.

antennee with the second and fourth joints subequal in Jength; pronotum with the lateral margins

coarsely crenulate ; ventral spine short, not passing the posterior coxe.

Long. 10 millim., lat. pronot. angl. 7 millim.

Hab. GuatemMata, Volcan de Atitlan 2500 feet (Champion).

This species, of which we possess but a single example, is allied to P. congrex, Stal,

from which it differs in the greater length of the pronotal angles, the callosities on

the anterior pronotal area, &c.

2. Melanodermus picipes.

Melanodermus picipes, Stal, En. Hem. ii. p. 14, 37.

Hab. Mexico (Sallé); Guatemata, Senahu (Champion); Panama, Bugaba, Volcan

de Chiriqui 2000 to 3000 feet (Champion).—CotomB1a, Bogota }.

This species is distinguished from IJ. tartareus, Stél (a Mexican species already

- enumerated and figured in this work), by the shorter second joint of the antenne and

the more angulated apex of the scutellum ; the antenne have the fifth joint luteous at

the base and a little longer than the fourth joint.

M. tartareus does not appear to extend further south than Mexico, and the speci-

mens collected in the State of Panama and recorded at p. 327, under the name of that

species, should have been ascribed, as above, to M. picipes, Stal.

3. Melanodermus castaneus, n. sp.

Closely allied to M. picipes, but differing from that species in the following characters:—the body, legs, and

antenne are castaneous, the third and fifth joints of the antenne are about equal in length, and

considerably longer than the fourth joint, and the scutellum is a little longer.

Long. 11 millim.

Hab. Nicaraeua, Chontales (Janson).

We have only received a single example of this species.

456 APPENDIX.

EUSCHISTUS (pp. 58, 329).

12. Kuschistus integellus, n. sp.

Dark castaneous, very thickly and coarsely punctate; antenne, eyes, base of lateral margin of corium,

connexivum, body beneath, and legs ochraceous ; antenn# with the first and second joints more or less

spotted with black, apical halves of the third, fourth, and fifth joints black; legs spotted with black;

membrane cupreous ; body beneath thickly punctured with black; apex of scutellum and a small spot

on posterior disk of corium pale ochraceous. Antenne with the second and third joints subequal in

length, shorter than the fourth and fifth joints, which are also about equally long; pronotal angles

prominent and broadly subacute, the pronotal lateral margins entire, excepting a spine at anterior angles ;

tibie profoundly sulcated beneath.

Long. 9 millim., lat. pronot. angl. 54 millim.

Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion).

This species, of which I have seen six examples, is allied to E. integer, St&l, by the

character of the non-denticulated and non-crenulated lateral margins of the pronotum.

ATIZIES, gen. nov. (To precede the genus Berecynthus, p. 61.)

Allied to Huschistus, but differing in the very short and non-sulcated tibiw, and the incrassated tarsi, of which

the second joint is very short, and the third subequal in length to, or slightly longer than, the first ;

central lobe of the head a little shorter than the lateral lobes; lateral margins of the pronotum

anteriorly slightly crenulate but not denticulate ; rostrum reaching the posterior coxe.

1. Atizies suffultus, n. sp. (Tab. XXXIX. fig. 20.)

Ochraceous, very thickly and castaneously punctate; antenne with the first and second joints ochraceous, the

remaining joints pale castaneous ; connexivum ochraceous, with the margins of the incisures castaneous ;

membrane pale fuscous, with the apex pale hyaline *; body beneath and legs ochraceous, the tarsi and

apices of the tibie pale castaneous.

Long. 8 millim., lat. pronot. angl. 5 millim.

Hab. Muxico, Chilpancingo in Guerrero (H. H. Smith).

A single example.

CAPIVACCIUS, gen. nov. (To precede the genus Hymenarcys, p. 63.)

Body broad, ovate; head long and broad, about as long as the pronotum, the lateral margins concavely

sinuate, the central lobe slightly longer than the lateral lobes; antenne with the first joint short, second

joint a little longer than first and not extending much beyond the apex of head, third, fourth, and fifth

joints subequal in length; pronotum about twice as broad as long, its lateral angles subprominent ;

scutellum very broad, extending beyond the middle of abdomen, its apex broadly rounded; membrane

extending beyond the apex of the abdomen ; tibiew distinctly sulcated. (Rostrum inaccessible, owing to

the typical specimen being carded.)

This genus is most closely allied to Tibraca, Stal, from which it differs in the

shape of the pronotum, and the non-foveate basal angles of the scutellum.

* In descriptions of Rhynchota, the stated colour of the membrane is very often referable to its apparent

hue, or to the reflection of the darker abdomen beneath.

HEMIPTERA-HETEROPTERA. 457

1. Capivaccius bufo, n. sp. (Tab. XX XIX. fig. 21.)

Ochraceous ; eyes, a triangular fascia on basal half of scutellum and the apex of same, a large irregular discal

spot to corium, and membrane (excluding apex) dark castaneous; antenne castaneous, apex of fourth

joint and base of fifth joint ochraceous; body beneath and legs ochraceous (imperfectly seen in carded

specimen). The head is thickly and coarsely punctate; the pronotum is coarsely punctate and transversely

rugose ; the scutellum is punctate and obscurely transversely wrinkled; the corium is thickly punctate.

Long. 8 millim.

Hab. Panama, Caldera (Champion).

A single example.

CRATO, gen. nov. (To follow the genus Capivaccius.) |

Head very large, but shorter than the pronotum, central lobe reaching the apex of the head, the lateral

margins strongly sinuated, the apex convexly rounded; eyes prominent; antenne with the basal joint

short and not nearly reaching the apex of the head, second and third joints subequal in length, shorter

than the fourth and fifth joints, which are also about equally long and moderately incrassated. Pronotum

depressed from near base, the lateral angles moderately prominent and rounded, the lateral margins

slightly sinuate, anterior margin moderately concave, anterior area with two transverse slightly raised

callosities. Scutellum about as long as the head and pronotum together, wide at base, narrowed to apex,

which is obtusely rounded. Membrane passing the apex of the abdomen. (Rostrum inaccessible, owing to

the typical specimen being carded.)

1. Crato urbicus, n. sp. (Tab. XX XIX. fig. 22.)

Ochraceous ; eyes, margins of central lobe to head, two central lines on anterior area, a spot at each anterior

angle and the basal area of pronotum, small basal spots, longitudinal punctures, and apex to scutellum,

and spots to connexivum fuscous; antenne ochraceous, apices of the third, fourth, and fifth joints

castaneous ; membrane pale hyaline, the venation pale fuscous. The body above is thickly and very

coarsely punctate, the base of the pronotum being rugulose.

Long. 6 millim., lat. pronot. angl. 4 millim.

EDESSA (pp. 86, 342).

12 (c). Edessa obnixa, n. sp.

Olivaceous ; body beneath, antenne, and legs ochraceous ; body beneath variegated with olivaceous; pronotum

with the lateral margins very narrowly ochraceous, the apices of the lateral angles black; membrane

connexivum spotted with ochraceous; second and third joints of the antenne subequal in length ;

pronotal angles slightly recurved.

Long. 13 millim., lat. pronot. angl. 9 millim.

Hab. Mexico, San Lorenzo near Cordova (MU. Trujillo); GuatemaLa, Las Mercedes

(Champion).

We had formerly received a mutilated specimen of this species taken by Mr. Cham-

pion in Guatemala; a second example now received from Mexico enables me to

describe it.

Edessa montezuma (p. 91).

The locality ‘‘Ocafia” quoted by me is probably in Colombia and not in Mexico as

stated. The insect was sent to me by Signoret as from Mexico.

I have followed Stal and Berg in treating the form costalis, Stal, as a var. of fulvipes,

Dall., though I am doubtful as to their specific identity.

ACANTHOSOMA (p. 100).

2. Acanthosoma flammatum, n. sp.

Reddish-ochraceous, very coarsely and thickly punctate; apex of fourth joint of antenne beneath, apical two-

thirds of fifth joint, lateral margins of central lobe and centre of basal margin to head, and quadrate spots

to connexivum black ; lateral angles to pronotum, basal half of scutellum, and a central marginal patch

to corium castaneous ; apex of scutellum, base of lateral margins to corium, and the legs ochraceous ;

(Champion); Panama, Bugaba, Volcan de Chiriqui, David, Tolé (Champion).

GALEOTTUS, gen. nov. (To precede the genus Trachelium, p. 159.)

Head very large, longer than the pronotum ; eyes inserted at about one-third from base, from whence to base

the head is gradually constricted ; antenne inserted about halfway between eyes and apex, first joint a little

longer than either second or third joints, which are subequal in length, fourth joint as long as second and

third together. Pronotum with the anterior margin convex, the lateral angles spinous, the basal margin

straight and toothed near basal angles of scutellum. Scutellum broad, subtriangular, slightly foveate at

each basal angle, the fovez followed by an obscure nodule on each lateral margin, the apex slender and

acute. Corium rudimentary, not extending beyond the centre of the abdomen, which beyond the corium

is somewhat gibbous and possesses two pairs of central discal tubercles. Posterior femora spined

beneath at apices ; posterior tibie unarmed at apices. Rostrum almost reaching the posterior coxa.

It is probable that the species for whose reception I am compelled to propose this

genus is in an undeveloped condition ; but this only applies to the corium, and the

other characters, especially of the head and scutellum, are strikingly distinct from

those of any other genus of the American Micrelytraria.

1. Galeottus formicarius, n. sp. (Tab. XX XIX. fig. 23.)

Very pale castaneous; pronotum ochraceous; abdominal tubercles black; structural characters as in the

preceding generic diagnosis.

Long. 10 millim.

Hab. Guatemata (Conradt); Nicaraeua, Chontales (Janson).

A single example from Nicaragua—which is here figured—is alone in such condition

as to render description possible. Several specimens sent by Conradt in spirits from

Guatemala undoubtedly also belong to the same species. They were all in the same

condition of development.

BACTRODOSOMA. (To precede the genus Protenor, p. 160.)

Bactrodosoma, Stal, Rio Jan. Hem. i. p. 34 (1860) ; Ofv. Vet.-Ak. Férh. 1867, p. 543.

This genus is allied to both Protenor and Darmistus, already included in our fauna,

but differs from both in having the pronotum not prominently narrowed anteriorly,

but with the lateral margins subparallel.

1. Bactrodosoma elongatum, n. sp. (Tab. XXXIX. fig. 27.)

Brownish-ochraceous ; fourth joint of the antenne (excluding base), rostrum (excluding basal joint), tibie,

and membrane pale fuscous; ocelli castaneous ; body beneath ochraceous, with the lateral margins pale

fuscous; head, pronotum, scutellum, and clavus thickly punctate; corium with the inner and lateral

areas punctate, the disk impunctate ; lateral angles of the pronotum subnodulose ; antenne finely setose,

the first, second, and fourth joints subequal in length, the third joint shortest ; tibia finely setose.

Long. 12 millim.

A single example.

CURUPIRA. (To follow the genus Leptocorisa, p. 162.)

Curupira, Distant, Compt. Rend. Soc. Ent. Belg. 1888, p. xi.

I proposed this genus for the reception of a species from Rio Janeiro. I am now

able to add another species from the State of Panama.

1. Curupira villosa, n. sp. (Tab. XXXIX. fig. 24.)

Head, pronotum, and scutellum black, very thickly greyish pilose; eyes pale castaneous; antenne, apical

spine to scutellum, hemelytra, connexivum, and legs ochraceous; head beneath and sternum Dlack ;

abdomen beneath ochraceous, its base, apex, and sometimes the whole of lateral margins black; abdomen

above with the apical area black; apices of the tarsi fuscous. The head, pronotum, and sternum are

coarsely punctate; the apical spine to the scutellum is long, slender, and slightly directed backwardly ;

the second and third joints of the antenne are subequal in length and each shorter than the fourth.

Long. 8-9 millim.

Hab. Panama, Caldera in Chiriqui (Champion).

Mr. Champion procured us a series of examples of this species.

STENOCEPHALUS. (To follow the genus Curupira).

Stenocephalus, Latreille, Fam. Nat. p. 421 (1825); Dall. List Hem. ii. p. 481 (1852).

A very widely distributed genus, most numerously represented in the Old World.

Neides, Fieber, Eur. Hem. pp. 54 & 209 (1861) ; Stal, En. Hem. iv. p. 127 (1874).

This genus, widely distributed throughout the Palearctic and Nearctic regions, and

also recorded from New Zealand, is now included in the Neotropical fauna on account

of the presence of the following species.

1. Neides caducus, n. sp.

Pale ochraceous ; margins and a central line to pronotum, a central fascia to scutellum, and margins of clavus

stramineous ; apical joint of the antenne (excluding base and apex) and the tarsi fuscous ; head beneath

with a pale stramineous longitudinal fascia on each side. The pronotum is very coarsely and thickly

HEMIPTERA-HETEROPTERA. 461

punctate ; the head is twice as long as broad and the pronotum twice as long as its basal breadth, with

its lateral angles distinctly nodulose.

Long. 8-10 millim.

Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith); Panama, Volcan de Chiriqui

8000 feet (Champion).

Mr. Smith took six specimens of this species in Mexico, and Mr. Champion found

another example on the Volcan de Chiriqui. I have carefully compared WV. caducus

with the description of N. gracilipes, Stal, found throughout the United States, from

which it appears to be quite distinct.

XENOGENUS. (To follow the genus Harmostes, p. 168.)

Xenogenus, Berg, Hem. Argent., Add. & Emend. p. 45 (1884).

This genus can at once be distinguished from Harmostes by the non-produced and

non-spined antenniferous tubercles, the elevated ocelli, elongate body, &c.

Xenogenus was founded for the reception of a species received from the Argentine

Republic and Uruguay.

1. Xenogenus extensum, n. sp. (Tab. XXXIX. fig. 26.)

Head, antennex, pronotum, scutellum, body beneath, and legs pale ochraceous; corium and membrane pale

hyaline, the corium with the margins and veins ochraceous, spotted with carmine-red, and with a distinct

fuscous spot near inner angle and at apex; membrane pale hyaline; femora spotted with brownish, the

spines of the posterior tibia black ; tibiee spotted with black, the apices of the tarsi also black ; antennse

with the basal joint margined with black externally and about reaching the apex of the head, second and

third joints subequal in length and only very slightly longer than the fourth joint; lateral margins of the

pronotum entire, neither crenulated nor serrated; pronotum coarsely and thickly punctate, with a

central pale levigate line; head and scutellum finely and sparingly punctate; body beneath finely

punctate and spotted with carmine-red.

Long. 8 millim.

Hab. Mexico, Orizaba (Ff. D. G.).

Only a single example of this species was obtained; it has many characters in

common with X. picturatum, Berg, found in the Argentine fauna.

RENODAUS, gen. nov. (To follow the genus Pheaz, p. 413.)

Head large, broad, and subtriangular, posterior margin equal in width to anterior margin of pronotum, the eyes

non-prominent, the apex somewhat acute, the central lobe prominent; antennz inserted about midway

between the eyes and apex, first joint shorter than the head, second joint longest, third short and

strongly incrassated towards apex, fourth incrassated and longer than third; ocelli absent. Pronotum

somewhat long, the posterior margin convex, gibbous near centre and from thence angularly depressed to

base; lateral margins sinuate, the lateral angles subprominent, the anterior angles rounded. Scutellum

very small, its apex subnodulose. Corium with the lateral margin concavely sinuate near base and

widened towards apex; membrane small. Rostrum about reaching the intermediate coxe. Femora

moderately incrassated ; posterior tibiz long.

This is another of those aberrant genera of Pyrrhocoride already represented by

Arhaphe, Japetus, and Pheax.

1. Renodezus ficarius, n. sp. (Tab. XX XIX. fig. 25.)

Head and pronotum black or very dark castaneous ; corium, body beneath, and legs castaneous ; corium with

pearly-grey pubescence at base, centre, and near apex; membrane fuscous, with the apex paler; apices

of the femora ochraceous ; tarsi pale ochraceous, with their apices black.

Long. 34 millim.

Hab. Guaremaa, San Gerénimo and Cerro Zunil (Champion).

One specimen from each of the above localities constitutes our knowledge of this

interesting species.

Head ochraceous, its apex, eyes, and antenne black; pronotum and scutellum black, the last with its basal

angles ochraceous; corium black, thickly ochraceously pilose, and with its lateral margins ochraceous ;

cuneus pale fuscous, with its basal margin pale ochraceous; body beneath castaneous; legs pale ochra-

ceous, posterior femora (excluding base) castaneous ; tibie spotted with black; apices of the tarsi black ;

membrane pale fuscous, its lateral margins paler and the basal cells black margined with ochraceous.
