BRITISH ENTOMOLOGY.

OrverR VI.—HYMENOPTERA.

Wings four, rarely wanting, all membranaceous and naked, generally with
distinct ample unequal areolets, anterior largest, mostly with a conspicuous
stigma on the costa; posterior small, with few nervures; ocelli two or
three; mouth various; palpi four; mandibles exserted, horny, rarely
employed for mastication; prothorax obsolete, giving place to an ample
collar ; abdomen various, consisting of from 6 to 9 segments, and, in the
females, furnished at the apex with an ovipositor of 5-6 valves, or a sharp
sting, having in many instances a poison bag at its base, and two short
compressed styles; tarsi generally pentamerous, or 5-jointed. Metamorphosis
incomplete: /arva in some cases furnished with 6 unguiculated legs, and
with from 0 to 12 membranaceous ones, and with two simple eyes ; in others
without legs and vermiform ; pupa quiescent, folliculated, with the antenmne,
legs, and wings distinct, and resembling the imago.

Next to the Coleoptera this order appears to be the most numerous
in species; in fact, from the very great accession to their numbers
which the investigations of some entomologists in this country have
brought to light, it has been supposed to be more extensive; but the
number of Coleoptera have been silently increasing at the same
time, though it must not be disputed that amongst the parasitic
groups, discoveries of new species are almost daily taking place: the
order is considerably diversified in habit, and embraces in its extensive
grasp some of the most useful and valuable insects, as more parti-
cularly referred to hereafter. From the extent of the order it becomes
necessary to subdivide it into sections. I shall therefore proceed nearly
in conformity with the divisions adopted by Latreille, with the
alterations as pointed out in my Systematic Catalogue, commencing

with—

Section I. _TEREBRANTIA, Latreille,

In which the females are furnished with a laminated, or filiform, ovipositor 3

in a few resembling a sting, and valvular ; vagina bivalve, received in a canal
at the lower apex of the body, the valves compressed ; in some lamelliform,
in others elongate-cylindric, setaceous, filiform.

These insects, as also proposed by Latreille, may be further sub-

divided into—

A. Abdomen united to the thorax, along its whole breadth, without any
distinct peduncle: and
B. Abdomen united to the thorax by a distinct peduncle.
The subdivision A. embraces two families, viz.—

Famity I.—TENTHRIDINIDA, Leach.

Wings with the marginal areolets complete: mandibles more or less long,

terminated with teeth: labium with three lamine: mazillary palpi with 6
_ joints, labial with 4: ovzpositor composed of two serrated leaves, rarely

exserted: antenna various.

The insects of which this interesting family—which is rather
extensive—is composed vary considerably in habit amongst them-
selves; I shall, therefore, in order to facilitate their investigation,
subdivide them into the groups proposed by Leach, in the 3rd vol.
of the Zoological Miscellany, abridging the external characters there
given, as they appear well calculated to disunite the various groups
into which they seem naturally divisible. A considerable variation
exists in the number of legs of the larvee—some possessing only the
6 true legs, while others have from 2 to 18 prolegs: in the early stage
many of them are armed throughout their body with spines, while
others are destitute of armature : in general, they resemble the larve
of Lepidoptera, being fleshy, but gradually taper from the head,
which is distinct and scaly; they curl up when disturbed, and feed
upon living vegetable substances, some few forming galls: again,
some species are gregarious, and others solitary.

The females are furnished with a serrated ovipositor, which they
employ in forming chinks, wherein to deposit their eggs—thence
called Saw-jlies. The following are the British genera :-—

Antenne breves, clavate, 5-8 articulate.

In accordance with the principles before alluded to, I shall preceed

to describe the insects included by Leach in

§ 1. Antenne short and clavate, with the third joint the longest ; anterior wings
with 3 marginal and 2 submarginal areolets.

6 MANDIBULATA.—-HYMENOPTERA.

Genus I.—CIMBEX, Olivier.

Antenne clavate-capitate, 7-jointed, basal joint robust, 2nd minute, 3rd very
long and slender, 4th and 5th clavate-truncate, equal in length, 6th and 7th
coalescing, and forming an oblong ovate club: head as broad as the thorax :
ocelli 3: mandibles irregularly 3-dentate: body robust, obscurely villose:
wings ample, anterior with 2 marginal and 3 submarginal areolets, the 1st
of the latter receiving 2 recurrent nervures: abdomen cylindric in the males,
with the Ist segment deeply notched above, and having a membrane in the
emargination; ovate in the females: 4 posterior femora unarmed, thickened
in the males; tibie with 2 obtuse spurs at the apex.

Cimbex differs from the cognate genera, not only in the structure
of its antennze, but from having the labrum comparatively smaller,
the body less pilose, furnished with a large membrane at the base in
the males, and in which sex the 4 hinder femora are very much
incrassated and curved; the anterior tarsi with spiny processes
beneath, &c. The larve form a strong oval cocoon, in which they
change to pupa; they appear very difficult to rear, as I have expe-
rienced, having taken many ; but when found in the pupa state, they
have frequently produced the imago: in general, the species are very
rare.

Sp. 1. femorata. Violascente-nigra, subpubescentia, antennis luteis basi fuscis,
tarsis membranaque abdominali luteis, femoribus tibiisque cyaneo-atris, alis
hyalinis apice areolaque costali 2dé antice fuscescentibus. (long. corp. 11—
133 lin.; Exp. Alar. 20—25 lin.)

Ten. femorata. Linné.—Ci. femorata. Steph. Catal. 323. No. 3734.

Slightly pubescent; violet-black, the head and thorax of a deeper and less
violet tint; antenne luteous, with the base fuscous or black; abdomen
with its basal membrane luteous ; femora and tibie of a blue-black ; tarsi
luteous or testaceous ; wings hyaline, with the apex and second costal
areolet anteriorly fuscescent.

The male in this (as in the other species of the genus) has the abdomen less
robust, with the two posterior femora elongated and thickened.

One of my specimens has the three intermediate joints of the abdom:n above
dull ferruginous, and another the apex pitchy.

Extremely rare in England: it occurs near Windsor, and in

Darenth wood, towards the end of June.

Sp. 2. varians. Nigra, antennis tarsis membrandque abdominali luteis, alis
hyalinis, apice areolaque submarginali secundé fuscis. (Long. corp. 7—l1%
lin.; Exp. Alar. 15—20 lin.)

Ci. varians. Leach.—Steph. Catal. 324. No. 3735.

ia

d

TENTHREDINID#.—CIMBEX.

Head, thorax, and abdomen black ; legs the same ; tarsi, antenne, and basal
membrane of the abdomen luteous; wings hyaline, with the apex and
second submarginal areolet fuscous.

Extremely variable: some examples have the sides of the 3rd to the 6th
segments luteous or yellow, or a portion of the segments edged with, or
entirely luteous, or occasionally ferruginous. In some the tibie are black,
in others luteous or pale fuscous, and the claws in some rare instances fer-
ruginous; the coloured apex to the wings varies in intensity. These
varieties occur in both sexes.

Not very abundant: found at Darenth and Coombe woods: in this
last locality I once captured nearly twenty specimens one morning

early in June. It has been found in Scotland.

Sp. 3. pallida. Fusco-lutea, thorace pectoreque nigricantibus, abdomine pallide
luteo incisuris atris, antennis pedibusque pallide luteis, alis hyalinis apice
areolaque costali secundé fuscis. (ong. corp. 6% lin.; Exp. Alar. 17 lin.)

Ci. pallida. Steph. Catal. 324. No. 3736.

Dusky-luteous, with the thorax and breast blackish; abdomen pale lutecus,
with the base of the segments black, antenne and legs pale luteous; wings
hyaline, with the costa, the second areolet anteriorly and the apex deep
fuscous.

This insect resembles the foregoing in its wings, and Ci. Griffinii in the colour
of the abdomen and legs: it may be a very extraordinary variety of Ci.
varians.

Taken in June near Colney-hatch at Hollick wood.

tSp. 4. decemmaculata. Violascente-nigra, antennis tarsis et membrand abdo-=
minali luteis, abdomine segmentis 3—7 utrinque maculd (intermediis 6 majo-
ribus) flavd. (Long. corp. 10—11 lin.; Exp. Alar. 21—233 lin.)

Ci. decemmaculata. Leach.— Curtis, v. i. pl. 41.—Steph. Catal. 324. No. 3737.

Violet-black ; head, thorax, and abdomen beneath black; antenne, abdominal
membrane, and tarsi luteous ; abdomen above with a yellow spot on each
side of the 3rd to the 7th segments, the six intermediate ones being largest ;
wings of a slightly tawny hue, with the apex and second marginal areolet
darker.
Found near Windsor, but very rare.

Sp. 5. Griffinii. Lwutea, pectore saturatiore, abdomine flavo segmentorum inter-
stitis nigris, alis subfulvescentibus, areola secundd costali saturatiore. (Long.
corp. 11 lin.; Exp. Alar. 18—21 lin.)

Ci. Griffinii. Leach.—Steph. Catal. 324. No. 3738.—Te. lutea. Donovan,
Brit. Ins. v. vi. pl. 324 3.

Luteous ; breast, and sometimes the base of the abdomen slightly, darker or
fuscescent ; abdomen yellow, with the interstices (or base) of the segments
black, and with a dorsal line composed of ferruginous, or fuscescent dots ;

wings slightly fulvescent, with the second costal areolet and the apex
darker or slightly fuscescent.
Taken in the fens in the vicinity of Cambridge and Whittlesea ;

at times in great abundance, in June: also found near Norwich.

Sp. 6. annulata. Lwutea, abdomine flavo, thorace disco pectore abdominisque
segmentis duabus piceis tertioque macula subviolascente-fuscis, femoribus
violascente-luteis ; alis hyalinis apice fuscis. (Long. corp. 10—11 lin.; Exp.
Alar. 20—@3 lin.)

Ci annulata. Lceach.—Steph. Catal. 324. No. 3739.

Luteous; abdomen dull yellow, with a dorsal row of rusty dots, its base, er
rather the first two segments and a spot on the third, with the disc of the
thorax and the breast, of a violaccous-brown; femora of a violaceous-
luteous ; wings hyaline, sometimes a little fulvescent, with the second costal
areolet darker, and the apex slightly fuscous.

Taken near Windsor, and in the marshes about Cambridge ; alse

in Devonshire, in June and July.—Probably a variety of C. Griffin.

fSp. 7. maculata. Fusco-testacea wneo-nitens, capite antennis, tihiis tarsisque
luteis, abdomine flavo, segmentis tribus primis dorsalibus violascente-fuscis,
3-tio maculé utrinque flava, 4-to maculd dorsali fusco-violacea. (Long. corp.
10—12 lin.; Exp. Alar. 21—24 lin.)

Cra. maculata. Fourcroy:—Cix maculata., Steph- Catal. 324. No. 3740.

Testaceous-brown, with a brassy tint; head, antenne, tibie, and tarsi, dull
Juteous; abdomen yellow, with the three basal segments on the back vio-
Jaceous- or brassy-brown, and a spot of the same on the 4th; the 3rd with
a yellow or luteous spot on each side ; wings hyaline, with the costa and
the second areolet darker, the nervures testaceous-brown.

Scarce: found at Darenth wood.

{Sp. 8. humeralis. Migra, antennis pedibusque luteis, fronte thoracis angulis
anticis abdomineque flavis ; hoc superné segmentis 1, 2, et 4 fuscis, externé
maculd flava notatis, aliis medio macula fusca, alis hyalinis anticé fulvescentibus,
fusco variis. (Long. corp. 94 lin.; Exp. Alar. 173 lin.)

Cra. humeralis. £ourcroy.—Ci. humeralis. Steph. Catal. 324. No. 3741.

Black ; head, scutellum and pleure rusty-luteous ; antenne and legs luteous,
the four posterior femora black in front: the forehead, anterior angles of
the thorax and abdomen yellow ; the latter with the Ist, 2nd, and 4th seg-
ments fuscous, with a yellow spot externally, the remainder with a fuscous
spot on the back ; wings hyaline, with the costa fulvescent, and the apex
clouded with fuscous.

Very rare: found near Salisbury.

Genus I1.—TRICHIOSOMA, Leach.

Antenne slender, clavate-capitate, 8-jointed, basal joint robust and rounded,

TENTHRIDINIDE.—TRICHIOSOMA. 9

pilose, 2nd minute, 3rd nearly half the length of the antenne, very slender,
2 next stouter and shorter, equal in length with each other, 6th obconic,
forming part of the club, the latter completed by 2 coalesced joints : head
scarcely so wide as the thorax: ocelli 3: mandibles generally bidentate :
wings as in Cimbex: body robust, villose: abdomen cylindric and elongate
in the males, slightly notched above at the base, ovate and depressed in the
females: 4 posterior femora thickened aud dentate within in the males ;
tibie furnished with a pair of obtuse spurs.

The more densely pilose body of the insects of this genus, combined
with the greater s!enderness of the antennee, which, as pointed out by
Mr. Curtis, are punctured, as well as the larger labrum, the dentate
thickened posterior femora of the males, the simplicity of the tarsi,
&c. sufficiently indicate their distinction from Cimbex: in metamor-
phosis they, however, resemble the insects of that genus, but they
appear in the imago still earlier in the year.

Sp. 1. sylvaticum. Subeneo-atrum, abdomine nigro-wneo subtus sordidé luteo
fusco marginato, femoribus cyaneo-atris, tibiis tarsisque lutets. (Long. corp.
8 lin.; Exp. Alar. 16—18 lin.)

Tr. sylvaticum. Leach.—Steph. Catal. 324. No. 3742.

Of a deep brassy black ; abdomen above with an ashy pile, beneath dull
luteous, margined with fuscous; femora blue-black; tibie and tarsi
luteous ; wings hyaline, slightly fulvescent, with the apex more or less
fuscous ; mandibles red at the tip, with obsolete teeth; antenne brassy-
black ; labrum pentagonal.

The sides of the abdomen are sometimes edged with luteous-red, in addition
to the pale under surface.

Not common: taken occasionally at Darenth wood and. near

Edinburgh.

Sp. 2. laterale. Migro-eneum, capite saturatiore, antennis nigris, femoribus
cyaneo-atris, tibiis tarsis ventre lateribusque abdominis luteis. (Long. corp.
10—12 lin.; Exp. Alar. 18—@ lin.)

Ti. laterale. Leach.—Curtis, v. i. pl. 49.—Steph. Catal. 324. No. 3743.

Brassy-black: head deepest ; antenne black ; abdomen with a slightly ferru-
ginous pile, its under surface and sides luteous-red ; femora blue-black ;
tibie and tarsi luteous; wings somewhat fulvescent, with the apex more or
less fuscous ; mandibles deep black, with the apex pitchy ; labrum with the
angles rounded.

Also found at Datenth wood, more abundantly than the last; and

occasionally at Coombe wood, in April and May.

Sp. 3. Latreillii. neo-nigrum, capile antennisque nigris, abdomine supra pur-
nurascente-nivro, femoribus violuscentibus, tibits larsisque luteis. (Long. corp.
P ey) 2 q
9—11 lin.; Exp. Alar. 18—20 lin.)

Brassy-black, with a ferruginous pile; head and antenne black ; abdomen
purplish-black ; femora slightly violet ; tibie and tarsi luteous; wings
hyaline, fulvescent, with the apex fuscous; labrum of the male nearly
rounded.

The two joints preceding the club of the antenne are sometimes ferruginous.
In the late Mr. Haworth’s collection was an example of this

species; and I obtained one from that of Mr. Bainbridge; probably

taken near London.

Sp. 4. Lucorum. Migrum, thorace eneo-nigro, femoribus cyaneo-atris, tibiis
tarsisque luteis, labro $ magno. (Long. corp. 6—10 lin.; Exp. Alar. 15—
18+ lin.)

Black; thorax rather brassy, clothed with a fine reddish-ash pubescence ;
femora dull blue-black ; tibie and tarsi luteous; wings hyaline, with the
apex slightly fuscescent ; labrum of the male large and rounded, of the
female small.

The tibie are sometimes slightly fuscescent.

Deep black, rather opaque, and {densely clothed with a griseous pubescence ;
femora blue-black; tibiee and tarsi dull luteous ; antennepitchy-black,
ferruginous in the middle; abdomen very slender in the male, and but
slightly dilated in the female, its apex in both sexes furnished with two
exserted luteous-red tubercles.

Taken near Teignmouth in Devonshire.

Genus III.—CLAVELLARIA, Leach.

Antenne 5-jointed, shortest in the females ; basal joint robust, 2nd transverse,
3rd very long and slender, 4th short, 5th forming a club as long as the 3rd,
and punctured : labrum large ; mandibles dentate, long in the males: head
nearly as wide as the thorax: eyes not approximating: ocelli 3: wings as in
Cimbex: body slightly villose: abdomen linear in the males, with the basal
joint slightly emarginate, a little dilated towards the apex, and depressed on
the back in the females; legs rather short; 4 posterior femora unarmed,
thickened in the males ; tibia furnished with obtuse spurs at the apex.

The 5-jointed antennz of the insects of this genus, exclusively of
the difference in the trophi, the slightly emarginated abdomen, the
base of which is not furnished with a membrane, the simple hinder
femora, extraordinary length of the mandibles of the males, longer
labrum, &c. sufficiently point out its distinction from the two pre-
ceding, with which it is generally included: the difference of habit
alone seems to call for a separation, setting aside the differences above

alluded to; the sexes (if such they be) being very dissimilar to each
other.

Sp. 1. Amerine. Nigra cinereo-pubescens, labro clypeoque albidis, antennis
articulo ultimo tibiis tarsis ventre anoque ferrugineo-testaceis. (Long. corp.
9—9 lin.; Exp. Alar. 14—15 lin.)

Te. Amerine. Linné.—Cl. Amerine. Steph. Catal. 325. No. 3749.

Black, with an ashy pubescence; labrum and clypeus whitish, the former
strongly cordate, with the base much rounded ; antenne ferruginous at the
apex ; abdomen the same beneath, its apex and two last segments above
more luteous ; legs rusty-testaceous, with the femora black; wings hyaline,
with the second areolet and the apex brownish.

I have never seen the female (unless, as I strongly suspect, the following insect
be it) ; but, according to Olivier, it differs in having nearly the entire upper
part of the abdomen entirely testaceous, and the femora blue-back.

The larva feeds on the willow. oe
Of this very rare insect the only examples I have seen were

captured near Windsor; one being in the British Museum, the other

in my own collection.

Sp. 2. marginata. Nigra, antennis apice tibiis tarsisque luteis, abdomine seg-
mentis posticis margine ventris fasciis et margine labroque albis. (Long.
cerp. 8—10 lin.; Exp. Alar. 15—18 lin.)

Te. marginata. Linné.—Cl. marginata. Curtis, v. il. pl. 93.—Steph. Catal. 325. -
No. 3750.

Black ; head and thorax with a slight ashy pile; antenne with the apex
ferruginous; labrum and anterior portion of the clypeus whitish ; abdomen
somewhat glabrous, the two basal segments entirely black, the remainder
with broad whitish margins, of which the first two, on the 3rd and 4th
segments, are interrupted; all the segments beneath also margined with
yellow-white ; apex ferruginous; legs black, with luteo-testaceous tibie
and tarsi; wings hyaline, with the second costal areolet and the apex fus-
cescent. ‘ ;
Of this (which I suspect to be the female of the preceding), the:

specimens in the British Museum and my own collection are the only

examples I have seen: they were taken near Windsor.

Genus IV —ZARJA, Leach.

Antenne 6-jointed, short, two basal joints transverse, 3rd long, slender, a little
curved, 4th short, rather stouter, 5th and 6th forming a club, with an obtuse
apex: mazillary palpi composed of 6 unequal joints, the first three being
short, the others more or less elongated: head small, much narrower than

.the thorax: eyes united behind in the male: ocelli 3: wings as in Cimbex :
body glabrous: abdomen cylindric in the males, ovate in the females ; the

TENTHR!IDINID©—ZAREA.—ABIA. 13

basal segment not emarginated: legs slender; femora not incrassated in the
males; tibie armed with 2 obtuse spurs at the apex.

The 6-jointed antennze of Zareea distinguish this genus from the
other genera of this group, and from all the preceding the cissimi-
larity in the proportions of the basal and terminal joints of the palpi,
also serve to remove it, as de likewise the fasciated wings, small head,
having the eyes approximating behind in the males, and other difier-
ences in the trophi.

Sp. 1. fasciata. Aineo-utra, tibiis tarsisque luteis, alis anticis fascid fused ;
abdominis 2 basi aibido. (Long. corp. 5—6 lin.; Exp. Alar. 10—113 lin.)

Te. fasciata. Linné.—Za. fasciata. Curtis, v. ii. pl. 91.—Steph. Catal. 325.
No. 3751. - :

Brassy-black ; thorax with its extreme hinder margin whitish ; abdomen with
the basal segment also whitish and diaphanous ; legs black, with the tibiz
and tarsi dull luteous; wings hyaline, with a central fascieform fuscous
spot.

The male is said to differ in having the basal segment of the abdomen conco-
lorous with the others.

Not very uncommon within the metropolitan district: it has been
taken at Highgate and at Birch and Coombe woods; in the latter
places in some plenty in June and July: the males appear to be

very scarce.

Genus V.—ABIA, Leach.

Antenne 7-jointed, short, 2 hasal joints transverse, 3rd very long, bent, 4th and
5th of equal length, more robust, 2 following very short, and forming an ob-
tuse club: mazillary palpi of 6 unequal joints: head very small: eyes nearly
united behind in the male: ocelli 3: wings as in Cimbex: body villose,
cylindric, and adorned with a velvety dorsal patch in the males, broader
and ovate in the females ; the base not emarginate: degs short and slender,
femora not incrassated in the males; tiie armed at the tip with rather
obtuse spurs. :

Abia differs from the cognate genus in having 7 articulations to the
antennz ; the body of a rich metallic silken hue, the males having a
raised velvety patch on the back of the abdomen, which latter in the
females is broad, ovate and destitute of the patch: the insects are

comparatively of small size, and appear to be gregarious.

Sp. 1. nigricornis. Subvillosa, nigro-enea, antennis ferrugineis, abdomine viridi-
aneo, pedibus flavis, femoribus nigro-eneis, alis nebuld media maculaque
apicali fuscescentibus. (Long. corp. 44—5 lin.; Exp. Alar. 9—11 lin.)

Ab. nigricornis. Leach.—Curtis, v. ii: pl. 89.—Steph. Catal. 325. No. 3752.

14 MANDIBULATA.—HYMENOPTERA.

Head and thorax brassy-black, slightly villose ; antenne deep black ; abdomen
greenish-brass; femora brassy-black; tibie and tarsi luteous-yellow ;
wings of a dull brownish-luteous, with an irregular cloud in the middle,
and the apex fuscous.

The male has the wings and markings thereon of a deeper hue, and a broad
orate dull velvety-black spot in the middle of the 4th, 5th, and 6th seg-
ments of the abdomen. The antenne are sometimes brownish at the apex.
Taken occasionally in the woods about London, in June: I have

found it at Coombe and Darenth.

Sp. 2. sericea. Subvillosa, nigro-enea, antennis ferruginers, abdomine supra
viridi-eneo, pedibus luteis femoribus basi nigro-eneis, alis nebuld media
strigdque apicali fuscescentibus. (Long. corp. 44—5% lin.; Exp. Alar. 9—
11 lin.)

Te. sericea. Linné.—Donovan, v. xii. pl. 402.—Ab. sericea. Steph. Catal.
325. No. 3753.

Head and thorax brassy-black, the sides of the latter sometimes greenish ;
antenne ferruginous, or luteous; abdomen bright greenish-brass above,
blackish beneath, with the sides greenish ; legs luteous, with the femora at
the base brassy-black or purplish; wings hyaline, with a somewhat
triangular brownish cloud in the middle, and a streak of the same at the
apex.

The male has a narrow, elongate, velvety-black patch on the middle of the
Ath, 5th, 6th, and 7th segments of the abdomen.

Also found in the vicinity of the metropolis, in June, on heaths,
and in woods: I once met with it in utter profusion flying round an

old willow at Coombe wood.

Grnus VI.—AMASIS, Leach.

Antenne 5-jointed, 2 basal joints short, 3rd rather long and slender, 4th
shorter, 5th forming an obtuse club: mandibles bidentate: head small:
eyes not approximating in the males: wings nearly as in Cimbex, the last
submarginal areolet receiving 1 recurrent nervure, the 2nd two: body
naked, punctured: abdomen with the 1st segment entire: legs short; 4
posterior tibiz armed at the tip with a pair of acute spurs; tarsi with the
penultimate joint much shorter than the antepenultimate.

The acute pair of spurs at the apex of the 4 posterior tibize of
Amasis, exclusively of the different proportion of the joints of the
tarsi, and the different number of those of the antennee—which are
5 in number—the naked punctate depressed body, &c. sufficiently
point out its distinction from the ‘Tenthridinida with clavate
antennez.

Te. Jurine. St. Furgeau Mon. 38. No. 103.—Am. leta. Steph. Catal. 325:
No. 3755.

Black; abdomen with the basal joint anteriorly black, the 2nd black, with
the sides broadly saffron-coloured, the remaining segments of this last
colour, with the base of each on the back black; legs yellow, with the

_ femora at the base, the apex of the hinder tibie and of each joint of the tarsi
black ; wings pellucid.

The only examples I have seen of this pretty species are in the

British Museum: they were taken near Bristol.

§ 2. Antenne 3-jointed, filiform or subclavate ; ciliated or furcate in the males:
anterior wings with 1 marginal and 4 submarginal areolets: body short and
stout.

Genus VIIL—HYLOTOMA, Fabricius.

Antenne 3-jointed, 2 basal joints small, 3rd very long, filiform, and ciliated
on one side in the males, shorter and somewhat clavate in the females, and
nearly glabrous: /ubrum transverse : mandibles bidentate : head transverse,
with a tubercle between the antenne: wings ample, anterior with one
marginal areolet, emitting a nerve from the apex; [and 4 submarginal
areolets, the Qnd receiving 1 recurrent nervure, the 3rd 2, and the 4th
extending to the margin: body rather short and stout: legs simple in both
sexes, 4 posterior tibie with a spine on the inner side below the middle, and
two at the apex. Larva with 14 prolegs.

The singular 3-articulate simple antennz of these insects suffi-
ciently distinguish them from all the others of this family, excepting
the females of Schizocerus, but from which they may be instantly
known by the nervure, which is emitted at the apex of the marginal
areolet of the anterior wings, as well as the spine on the inner margin
of the 4 posterior tibie: it is, perhaps, matter of doubt whether
the antennz really consist of only 3 articulations, as it is probable
that if investigated with a very high power, the apparent elongated
3rd joint is composed of several closely united ones.

A. Antenne short, nearly filiform in the females, and pilose :—Prix1a,

Grxus VIII.—SCHIZOCERUS, Latreille.

Antenne 3-jointed, 2 basal joints short, 3rd elongate, furcate, with numerous
series of rigid hairs on each branch; in the female simple, filiform and
naked: mandibles unidentate: head transverse, with a frontal tubercle:
ocelli 3: wings ample, anterior with 1 perfect marginal areolet, and 3 im-
perfect nearly equal submarginal ones, the former with its nervure carried
to the apex: abdomen rather short: legs simple ; t¢bie with spines only at
the apex.

Both sexes of the insects of this genus may be known from
Hylotoma by having the marginal areolet of the anterior wings
complete, and not partially divided by a nervure, in addition to their
having the 4 hinder tibize not armed with a spur towards the middle
of the inner margin, and other differences in the trophi: the males
have a peculiarity in their antennae, which are singularly furcate, the
long terminal joint being divided into two long branches of equal
length, which are strongly ciliated on both sides: in the females this
joint is simple and filiform. |

Head, thorax, and abdomen shining brassy-black ; femora dusky-black, tibize
and tarsi pale ; wings hyaline, with a faint brownish fascia annexed to the
stigma, which is fuscous ; antenne black, faintly ciliated in the male.
Apparently very rare: I have taken both sexes at Coombe wood in

June, and the females at Birch wood, but I know of no other

locality.

§ 3. Antenne many-jointed, with a double series of pectinations beneath in the
males; thickened towards the middle, with the apex acuminated and
somewhat serrated within in the females; anterior wings with 1 ample
marginal areolet and 4 submarginal ones, the Ist of the latter sometimes
incomplete ; body broad, depressed.

Genus IX.—LOPHYRUS, Latreiille.

Antenne composed of numerous distinct articulations, the 2 basal ones straight
and simple, the remainder placed obliquely, and in the males producing on
each side a long ciliated ray, gradually decreasing in length to the apex,
the 3 or 4 terminal joints having but one ray, and the extreme one being
simple ; in the female they are thickened in the middle, and slightly serrated
within: mandibles tridentate: head transverse, wide in the males, small in
the females: ocelli 3: wings ample, anterior with 1 marginal and 4 sub-
marginal areolets, the first 2 of the latter with the divisional nervure
imperfect ; abdomen broad, depressed in the females: legs simple; tibie
with a pair of acute spurs at the apex only. Larva with 16 prolegs.
There is considerable disparity in the sexes of this genus, but each

may be readily known from the other genera of this family, by the

antennez alone; in the males these organs are strongly bipectinated

(as in many Lepidoptera), the pectinations, or rays, diminishing in

length to the apex of the antennee, the terminal joint being simple ;

in the females they are thickened in the middle, and slightly atte-

brownish. Female much depressed, whitish, or pale testaceous, with an
irregular patch on the middie of the thorax, and of the abdomen, the breast,
head, and antenne black, except the 2 basal joints of the last, which are
pale; the antenne 20 jointed. Some examples of this sex are more
distinctly spotted with black than others, and the spots vary in size.
Found in Scotland, and in Cumberland and Derbyshire; in the

former country near Edinburgh and in Dumfriesshire ; on the pine

in June: it is not common.

§ 4. Antenne 9-jointed, moderate or elongated ; anterior wings with 1 marginal
and 3—4 submarginal areolets ; body short.

Genus X.—CLADIUS, Leach.

Antenne with the 2 basal joints straight and short, the rest obliquely inserted,
pilose in the males, and occasionally furnished with an elongate process on
one side, giving a branched appearance ; in the females simple and slightly
pilose: mandibles unidentate: head transverse: ocelli 3: wings ample ;
anterior with 1 large marginal areolet, and 3 distinct submarginal ones, the
2nd short, and receiving a recurrent nervure in the middle, the Ist in some
species obscurely subdivided by a very indistinct nervure, producing the
appearance of 4 areolets: /egs simple: t¢bi¢ all with only a pair of spurs at
the apex. Larva with 18 prolegs.

Although some of the species of this genus closely approximate to
those of the 2 following genera, the difference in the structure of the
antennze, which, however, vary slightly in the species, and conse-
quently require a division in the genus, exclusively of the variation
in the neuration of the anterior wings, will sufficiently enable the
reader to distinguish them, the antennze being pilose in both sexes,
and in all the males the 3rd joint is more or less eccentric; in the
typical species that and the 3 following being all so constructed.

TENTHREDINID£E.——PRISTIFHORA. 95

Nematus, agreeing nearly in the neuration of the wings with the
former, and in the simplicity of its antennz with the latter: the males
have these last organs but slightly pubescent, and are destitute of
any appendage at the tip of the basal joints, and the females have
them very short and slender, and glabrous, by which character either
of the sexes may be known from Cladius; and from Nematus, the
want of the minute, rounded, submarginal areolet, distinguish them ;
though, it must be admitted, that the nervure which subdivides this
from the 2nd is occasionally very faint in the trwe Ne. pallipes.

Genus XII.—NEMATUS, Leach.

Antenne 9-jointed, elongate, slender, simple, 2 basal joints short, 3rd longest,
remainder gradually diminishing in length to the apex: head small, trans-
verse: mandibles dentate: ocelli 3: wings ample, anterior with 1 large
marginal areolet, and 4 submarginal ones, the Ist small, rounded, the rest
in general nearly equal to each other, the 2nd receiving 1 recurrent nervure,
the 3rd 2; this last areolet is occasionally minute: body short, subcylindric
in the males, broader and depressed in the females: legs simple: ¢ibie with
2 sharp spurs at the apex only.

It appears to me that this genus may be distinguished from Pristi-
phora by the simplicity and nakedness of the antennz, exclusively of
the variation in the neuration of the anterior wings, which, although
constructed upon the same model as in Pristiphora, differ in possessing
a distinct rounded submarginal areolet; for the variations that occa-
sionally take place in some of the first species, by the rudiments alone
of a nervure being perceptible,* ought not to militate against the
general rule, especially when we find there is a prevalent diversity of
habit between the insects of the respective genera, Pristiphora being
more closely allied to Cladius than to Nematus.

Genus XIITI.—CR@SUS, Leach.

Antenne 9-jointed, simple in both sexes, slightly pilose in the males, basal
joint short, 2nd shorter, 3rd longest, the remainder gradually decreasing in
length to the apex, which is attenuated: mandibles unidentate: labrum
rounded: head broad: ocelli 3: abdomen cylindric in the males; broader
and somewhat carinated in the females: wings ample; anterior with }
marginal, and 4 submarginal areolets, the Ist small, suhquadrate, 2nd
large, elongate, receiving 2 recurrent nervures, 3rd small, quadrate, 4th
extending to the apex: 4 anterior legs simple; posterior rather stout, their
tibie dilated at the apex; fars¢ with the basal joint longest, considerably
dilated and compressed, remaining joints small, simple.

Exclusively of other less conspicuous differences, Croesus differs
from Nematus in having the hinder tibie and the basal joint of the
hinder tarsi considerably dilated and compressed, a structure that
partially obtains in Ne. vicinus, but that insect is sufficiently removed
by its general habit; and as there are evidently several good species
of Croesus, it ought clearly to be considered as distinct from Nematus,
intervening forms, as elsewhere pointed out, not alone being suf-
ficient to unite discordant genera.

probably referrible to a distinct species.

The larva of this species feeds on the gooseberry.

Found at Barnet; also at Darenth, near Hertford, Dublin, and

in the north of England in June, but not very common.

Black: palpi reddish ; abdomen with the 3rd to the 6th segments ferruginous,
a streak of the same at the base of the 2nd, and a bifid spot on the 7th ;
anterior legs black, with the apex of the femora ferruginous in front, the
tibie and tarsi whitish-red, brownish at the tip ; intermediate black, with
the tibie and tarsi pitchy ; the former whitish at the base ; posterior black,
with the tip of the coxe, the trochanters, and the base of the tibia, ochreous-
white, the latter brightest; wings hyaline, faintly reddish, with a distinct,
somewhat obscurely ferruginous, clouded fascia beyond the middle, extending
from the base of the stigma to the posterior margin.

I have one example of this fine insect that was taken near London,
and a second I obtained from the Marshamian collection: it has, it
would appear, been taken at Bungay in Suffolk, if my reference be

correct.

40 MANDIBULATA.—HYMENOPTERA.

§ 5. Antenne short, 9 or 10-jointed, with the appearance of an 11th, thickened
in the middle, and acuminated at the apex, the 3rd joint longer
than the 4th ; body short and stout.

Grnus XIV.—MESSA, Leach.

Antenne rather slender, 9-jointed, two basal joints short and robust, 3rd
elongate, 4th shorter, remainder gradually diminishing in length to the
apex: mandibles small: labrum rounded: head transverse: wings ample ;
anterior with 1 marginal areolet, and 4 submarginal ones, the Ist small,
rounded, 2nd elongate, 3rd quadrate, 4th extending to the apex: body short,
acute at the apex: legs slender, simple, ¢7hie with two short acute spurs at
the tip.

From the other genera of this section Messa may be recognized by
the number of areolets in the anterior wings, there being but 1
marginal, and 4 submarginal ones, thereby agreeing in neuration with
the insects of the preceding section, from which, however, it differs in
the antennee, &c.

Genus XV.—FENUSA, Leach.

Antenne short, somewhat clavate, 9-jointed, the 2 basal joints minute, 3rd
elongate, 4th shorter, the remainder distinct, somewhat moniliform, gradually
diminishing in length to the apex, which is obtuse: labrum emarginate :
mandibles short, dentate within: head broad, transverse: ocelli 3: wings
ample; anterior with 2 marginal areolets of nearly equal size, and with 3
dissimilar submarginal ones, the Ist elongate, narrow and curved, 2nd
larger, broader, somewhat triangular, receiving 1 recurrent nervure ; 3rd
extending to the apex ; body short and stout: Jegs simple ; tibie with a pair
of short acute spurs at the apex.

The want of a fourth submarginal areolet, combined with the
presence of 2 marginal ones, and the short, subclavate, 9-jointed
antenne serve to distinguish this genus from its allies ; the species of
which it is composed are amongst the smallest of those included in
this family.

Antenne somewhat clavate, 10-jointed, the articulations rather indistinct, the
3rd joint longest, the 4th slightly shorter, the remainder very short, some-
what moniliform, the apical joint rather obtuse, with an obscure suture:
labrum generally rounded in front: mandibles rather short and acute,
bidentate: head transverse: ocelli 3: wings ample ; anterior with 2 nearly
equal marginal areolets, and 4 unequal submarginal ones, the 1st small,
subangulated ; 2nd also small, somewhat quadrate, 3rd elongate, irregular,
4th extending to the apex ; the 2nd receiving 1 recurrent nervure, the 3rd 2:

body short, acute : legs slender, simple, the ¢ibie furnished at the apex only,

with 2 acute spurs ; ¢arsi with each joint generally tipped with black.

Athalia, by possessing 4 submarginal and 2 marginal areolets, with
short 10-jointed antennz, the terminal joint bemg apparently divided,
&c. may be distinguished from Messa and Fenusa with facility: the
species included in the genus have a great similarity to each other,
and a very peculiar habit ; they are not very dissimilar in appearance
to some species of Hylotoma, but the great discrepancy in the
antennez at once serves to discriminate them.

Genus XVII.—SELANDRIA, Leach.

Antenne short, 9-jointed, 2 basal joints distinct, somewhat globose, remainder
less distinct, the 3rd as Jong as the 41h and Sth united, the rest gradually

TENTHREDINID £.—SELANDRIA. 45

diminishing in length and thickness to the apex, the terminal joint being

short, and somewhat conic: mandibles bidentate: labrum emarginate: head

broad: ocelli 3: wings ample, anterior thin, with 2 marginal areolets,
divided by a straight nervure, placed a little obliquely, and 4 submarginal
_ ones, the Ist small rounded, 2nd and 3rd of equal size, the former receiving

1 and the latter 2 recurrent nervures, the 4th larger, extending to the apex

of the wing: body broad, scarcely longer than the thorax, somewhat depressed

and ovate in the females: /egs simple, with a pair of short unequal spurs at
the apex of the tibiz alone.

Although in the structure of the wings there is great similarity
between the insects of this genus and in those of Allantus and
Tenthredo, nevertheless the brevity and stoutness of the antennze,
the shortness and ovate depressed bodies, the comparatively greater
amplitude of the wings, in which the marginal areolet is generally
divided by a straight nervure, will sufficiently distinguish them from
those genera, as will the areolets of the wings* from those contained
in the present section: the species are generally small, and of dark
and sombre colours, some of the early ones, however, simulating the

Athahie.

TEN THREDINID.E.—HEMICHROA. 55

Genus XVIII.—HEMICHROA?* mihi.

Antenne setaceous, 9-jointed, elongate, 2 basal joints short, remainder slender,
3rd and 4th long, of equal length, 5th rather shorter, the rest gradually
diminishing in length: clypeus deeply notched: labrum rounded: mandibles
bidentate within: mazillary palpi with the 2 basal joints short, 3rd broad
and longer, 2 following more elongate, 6 slender and curved ; labial with
‘the 3rd joint dilated: head large, produced between the antenne: eyes
small: ocelli 3: wings rather short, broad, ample, ,with 2 nearly equal
marginal areolets, divided by a straight nervure, and 4 submarginal ones,
the Ist small, rounded; 2nd longest, receiving 2 recurrent nervures ; 8rd
small, elongate-quadrate ; 4th extending to the apex ; abdomen short, some-
what robust: Jegs short, simple: ¢ibie with 2 spurs at the apex only.

This genus differs not only in general habit—as may be seen by
the figures (pl. xxxviii. f. 2.)—from Selandria, but also in the structure
and slenderness of its antennze, wings, &c.: the latter are particularly
prone to vary, especially the marginal areolet, scarcely two examples
occurring precisely alike; in some there is only 1 areolet, others
have 2, and some have the rudiments merely of the separating
nervure, while in others it extends either half way or nearly to the
margin: in general the species are of contrasted colours.

Sp.1. Alni. Prave xxxviii. f- 2.— Nigra, capite thoraceque rufo-testaceis, pedibus
anticis subtestaceis. (Long. corp. 33—4 lin. ; Exp. Alar. 8—83 lin.)

towards the end of June, and at Forest Hill on the 28th of July
last.

Sp. 2. rufa. Luteo-rufa, antennis, sterno, femoribusque posticis nigris, tibiis
posticis albidis, apice cum tarsis fuscis. (Long. corp. 33—4 lin. ; Exp. Alar.

Genus XIX.—SCIAPTERY X* mihi.

Antenne 9-jointed, irregular, rather short and stout, pilose, basal joint robust,
2nd smaller, subglobose, 3rd as long as the 4th and 5th united, the last
somewhat longer than the 6th, which with the remainder gradually diminish
in length and thickness, the apical one being smallest and rather optuse :
clypeus and labrum emarginated: head broad, large, rough: eyes small:
ocelli 3: wings short, broad, punctured ; anterior with 2 marginal areolets,
divided by a curved nervure, and with 6 submarginal ones, the basal one
small, rounded ; 2nd narrow, receiving 1 recurrent nervure ; 3rd somewhat
triangular, receiving 2 recurrent nervures; 4th not extending to the apex of
the wings: abdomen short, stout, depressed, broad, acute at the apex: legs
short, simple : tibia furnished at the tip alone with 2 short obtuse spurs.

In this genus the antenne are short, stout, and, as it were, some-
what distorted, the articulations being irregular; the body is broad,
depressed, and rugose; the wings short, broad, thick, the anterior
with the marginal areolets divided by a curved nervure, as in
Allantus, by which characters combined it may be known from the

other genera of this section.

Sp. 1. costalis. Capite thoraceque punctatis, abdomine levi ; nigra, abdomine

line beneath the antennse, with the shoulders, white; abdomen smooth,
black, with the 4 anterior segments milky-white on each side, and the
remainder entirely bordered with the same ; legs black, white anteriorly ;
wings thick, somewhat fuscous, with the costa and stigma ochreous, tinged
with ferruginous ; nervures brown.

Not common: found early in April at Hertford ; also at Coombe

rood and near Bristol.

§ 6. Antenne 9-jointed, moderate, or elongate; body moderate or elongate,
generally the latter ; anterior wings with 2 marginal areolets.

Genus XX.—ALLANTUS, Panzer.

Antenne somewhat clavate, or setaceous, 9-jointed, the 3rd joint longer than
the 4th, the remainder gradually decreasing in length: mandibles 2- or 4-
dentate: /abrum rounded: head broad, subquadrate, deeply emarginate
behind: eyes rather large: ocelli3: wings somewhat long and slender,
ample ; anterior with 2 marginal areolets, divided by a curved nervure, the
basal areolet being somewhat lanceolate, the apical one ax-shaped ; and 4
submarginal ones, the 1st small, somewhat angulated, 2nd narrow, receiv
ing 1 recurrent nervure, 3rd triangular, receiving 2 recurrent nervures, 4th
scarcely extending to the apex: abdomen elongate: legs slender; posterior,
especially in the males, elongate, and in that sex the hinder tarsi are dilated
at the base; the tibie furnished at the apex with 2 long acute spurs.
This is rather an extensive genus, and may be readily known from

the others belonging to this section by the structure of its antenne
and wings: it appears, however, to require considerable subdivision,
but probably all may with propriety be retained under one genus: the
species are generally of large size, and the males—especially in the
1st section—differ much from the females, and have the posterior
tarsi dilated, and generally of a dark hue: they are extremely
voracious in their final state, devouring other insects.

A. Antenne short, somewhat clavate at the tip.
a. Antenne entirely, or nearly all, yellow.

TENTHREDINID£E.—TENTHREDO. 73

acute in the females: legs simple; posterior rather elongate; tcbie fur-

nished with a pair of longish acute spurs at the apex only : tarsi slender.

Although the characters, drawn from the antennae—assigned by
Leach to discriminate these insects from Allantus—may not, upon a
rigid examination ef every species, appear sufficient to warrant their
separation into two genera, nevertheless there is manifestly too great
a diversity of habit between them to associate them together; there
is, moreover, considerable modification in the trophi, and, amongst
other external differences, the clypeus is scarcely emarginated in
these insects, whereas in those of the foregoing genus it is in general
deeply notched: the true Tenthredines are very prone to vary ;—
they are most of them distinguished by having the stigma of the
anterior wings of two colours, and the middle of the abdomen fre-

quently red.

A. Antenne very long and slender ; posterior Jegs considerably elongated.

Grxus XXII._DOSYTHEUS, Leach.

Antenne 9-jointed, filiform, moderately long, the 2 basal joints short and rather
stoutest, 3rd considerably longer than the 4th, which is scarcely longer than
the 5th, that and the remainder scarcely diminishing in length and thickness
to the apex, the terminal joint being rather the shortest : mandibles emar-

ginate ; labrum rounded ; clypeus deeply notched: head broad, produced
between the anteune: eyes alittle prominent : ocelli 3: wings rather short;
- anterior with 2 marginal areolets, divided by a straight nervure, and 3 sub-
marginal ones, the 1st small, somewhat rounded ; 2nd longest, and narrow,
receiving 3 recurrent nervures; 3rd broad, extending to the apex of the
wing: abdomen rather short and stout, depressed and obtuse in the males,
somewhat carinated and acute in the females; colours generally bright ;
legs simple, short ; posterior ¢ibie with a pair of spurs at the apex only.
The same remark, as to the relative proportion of the 3rd and
Ath jomts of the antenna, will apply to one or two of the species of
this genus and of Dolerus, but like the two foregoing there is consi-
derable diversity of habit between the respective insects, the Dosythei
jnvariably having the middle of the abdomen red, contrasted with
black, whereas the Doleri have that part entirely black, and the sexes
are scarcely dissimilar to each other, as in Dosytheus. I shall there-
fore follow Leach in considering them distinct, a consideration borne
out by a slight modification of the trophi in the two genera.

Genus XXIII—DOLERUS, Leach.

Antenne rather short and stout, 9-jointed, the 2 basal joints short, and some-
what more robust ; 3rd and 4th long, and equal in length, 5th and remainder
gradually shortening and diminishing in length, the terminal one being a
little attenuated at the apex, and about half as long as the 3rd: mandibles

basal one longest, the 2nd nearly triangular, and 3 submarginal areolets,
the Ist small and rounded, 2nd very long, curved and receiving 2 recurrent
nervures ; 3rd extending to the apex: abdomen rather stout, never fasciated
with bright colours, elongate in the males, and somewhat cylindric ; more
robust, and acute at the apex in the females: legs shortish, with 2 short,
acute, spurs at the apex of the tibize only. Larva with 16 prolegs.

As before alluded to, the insects of this genus may be known from
the Dosythei by the abdomen being always black, or having tints of
that colour, and never fasciated with red or yellow in the middle, a
character invariably present in the Dosythei, which, although the
structure of the antennee may not in all cases be sufficient to distin-
guish the two genera, will at once enable the reader to discriminate
them from each other: and from Emphytus the small, rounded, 1st
submarginal areolet, is a conspicuous mark of distinction.

Genus XXIV.—EMPHY TUS, Leach.

Antenne filiform, 9-jointed, basal joint somewhat robust, 2nd small, 3 follow-
ing nearly of equal length, more slender than the foregoing, the remainder
gradually diminishing in length and thickness, the terminal joint ovate :
labrum somewhat orbicular: head transverse: eyes prominent: ocelli 3:
thorax ovate, subconvex: wings rather short, anterior with 2 marginal and
3 submarginal areolets, the former divided by a slightly curved nervure ; of
the others, the 1st is elongate, somewhat linear and bent, receiving 1
recurrent nervure ; the 2nd short, nearly triangular, receiving 2 recurrent

94 MANDIBULATA.-—-HYMENOPTERA.

Genus XXV.—HETERARTHRUS* mihi.

Antenne 12- to 15-jointed, the 1st and 2nd short, 3rd nearly twice as long as
the 4th, remainder short and distinct: wings ample; anterior with 2 mar-
ginal areolets and 4 submarginal ones, the transverse nervures which form
the first areolet only commenced ; the 2nd areolet receiving 1 recurrent
nervure ; the 3rd receiving 2.

I have employed the above generic name to designate the only
British species of this genus, inasmuch as I have not seen the insect,
and without a comparison of it with the other discordant Tenthredini-
deous insects included by Klug in his division, none of which I
know, I am at a loss to say how far it may differ in habit—the
British species forms the type of the genus Decatria (Westwood),
which name, of course, may be eventually employed, should the
insect prove different from the other species alluded to above.

Sp. 1. ochropoda. Niger, nitidus, antennarum articulis 2-hus basalibus pedi-
busque flavescentibus, alis (presertim ad basin) infumatis, antennis 13-articu<

Shining black: 2 basal joints of the antenne pale yellow ; mandibles brown,
with the base white; wing scales and metathoracic tubercles white ; coxe
and trochanters black, the latter pale yellowish at the tips; femora and
tibie yellowish, the latter palest at the base; wings dusky at the base,
hyaline at the apex.

There was a specimen of this species in Mr. Ingpen’s collection,
which I believe he found in Kent.

Genus XXVI.—MELICERTA? mihi.

Antenne slender, the 2 basal joints short, of equal length, the 3rd linear,
nearly as long again as the 4th, the 5th and 6th almost equal in length, and
rather shorter than the 4th (remainder broken off); /abrum transverse,
entire: clypeus not emarginated: head broader than the thorax, slightly
produced in front between the eyes, the latter rather large: ocelli 3: thorax
somewhat globose: wings shortish; anterior with 2 marginal areolets, the
basal one small, ovate-triangular, the other ample, and 3 submarginal ones,
the 1st elongate curved, receiving 1 recurrent nervure; 2nd shorter, some-

TENTHREDINID£.—TARPA. 95

what ovate, shuttle-shaped, with the ends truncate, and receiving 2 recurrent

nervures ; 3rd extending to the apex: abdomen long and somewhat cylin-

drical: legs slender, simple, with 2 minute sharp spurs at the apex of the
tibie.

This genus not only differs in general habit from Emphytus, but
the structure of the wings is totally dissimilar—somewhat resembling
that of Dolerus and Dosytheus, imasmuch as the Ist submarginal
areolet is elongated, the 2nd small; but the great difference in the
antennze, form of thorax, abdomen, and legs, in addition to the total
diversity of colour, sufficiently point out its distinction from those

genera and from Emphytus, with which it has been improperly asso-
ciated.

Yellowish-white : head deep shining black ; labrum and antenne ochreous ;
therax with 2 abbreviated fuscous streaks in front, and 2 deep black streaks
on the sides beneath the wings; abdomen paler than the thorax, the base
of each segment, excepting the terminal one, with a broad fuscous fascia ;
legs entirely pale ochreous-white; wings hyaline, pale ochreous, with the
nervures and stigma yellowish.

Taken in Devonshire, apparently rare, I believe in June.

§ 7. Antenne composed of numerous articulations, moderate or elongated : body
moderate, depressed: wings with 2 marginal and 4 submarginal areolets :
posterior ¢ibie with spurs in the middle.

Genus XXVII.—TARPA, Fabricius.

Antenne pectinated or serrated, the 2 basal joints straight, the remainder
obliquely inserted; 1st and 3rd joints elongate, the 2nd very short, the rest
moderate: mandibles large, deeply bidentate at the apex: labrum elongate,
its palpi with the joints equal: head suborbiculate, as large as the thorax:
eyes moderate: ocelli 3: wings short, broad, rounded at the apex ; anterior
with 2 marginal areolets, the basal one semicircular, the other thrice as
large ; and 4 submarginal ones, the Ist small, the 2 next nearly equal to each
other, the 2nd receiving 1 recurrent nervure, the 3rd receiving 2, the 4th not
extending to the apex: legs slender; the 4 posterior ¢bie with 2 spurs at
the apex, and 2 in the middle, on the inner edge.

Tarpa differs, not only in general habit, from Lyda, but in several
minor variations of structure, of which one of the most conspicuous

external ones consists in the 4 hinder tibize possessing each but a
single pair of rather elongate sharp spurs in the middle of their ner
edge; Lyda having in addition thereto a single one placed higher up
towards the femora; the antenne are also very different in the two
genera, the body less depressed in Tarpa, the wings not so ample,

the hinder margin of the 4th to the 8th, and 2 fascie beneath yellow ; antenne
ferruginous, with the 2nd joint and the apex black ; legs testaceous, with
the tibie yellow, and the 4 anterior femora at the base, all the coxe, and the
hinder pair of spurs, black.

margin of all the segments—the first 2 interrupted—@ ventral fascia, and
the legs, yellow; the 4 anterior femora black at the base ; tarsi luteous ;
antenne ferruginous, with the basal joint yellow.

TENTHREDINIDE.—LYDA. OF

Genus XXVIII.—LYDA, Fabricius. .

Antenne setaceous, consisting of numerous articulations, stoutest in the males,
the basal joint most robust, 2nd minute, 3rd not longer than the Ist, the
remainder very gradually decreasing in Jength and thickness to the end, the
terminal joint being minute: clypeus semicircular, nearly concealing the

mouth: mandibles strongly bidentate: head very large, somewhat orbicular,
or, viewed from above, subquadrate: eyes small, prominent: ocelli 3: thorax
broad, slightly convex: wings large and broad; anterior with 2 marginal
areolets, the 3 basal ones being complete, the 1st smallest, nearly trian-
gular, the 2nd elongate and curved, the 2rd nearly parallelogrammic, the
4th incomplete, not extending to the apex: abdomen generally broad and
depressed, terminal joint elongate in the male; ovipositor short: legs
slender, shortish ; the 4 posterior tibia with a single spur in the middle,

2 below the middle and 2 at the apex. Larve gregarious, without prolegs,

the apex terminated with 2 horn-like protuberances.

The conspicuous and generally beautiful insects included in this
fine genus may be readily known from Tarpa, by having the antenne
simple, the body broader and more depressed, the wings also broader,
and the areolets somewhat dissimilar; and, in addition, the 4 posterior
tibie have only 1 spur in the middle, a pair below the middle, and
another pair at the apex. The species are mostly very rare, although
the larvee are gregarious, which must account for some of them
being somewhat common in particular localities, as hereafter men-
tioned.

104 MANDIBULATA.—HYMENOPTERA.

Cephus differs chiefly from Janus by having the antenne distinctly
clavate; the neuration of the wings is also discordant ; the abdomen
of the males more cylindric, not being dilated towards the apex,
which is obtuse, and in the females that jeint is considerably com-
pressed towards the tip, and the ovipositor is exserted: the penulti-
mate joint of the palpi is very smali, and is frequently produced on
one side, a character that does not appear to have been previously
noticed: the species frequent flowers.

Also rare: it has been taken in Devonshire and in the New Fores

in June; and the variety at Darenth wood at the same time of the

year.

Famity Il.—XIPHYDRIIDA, Leach.

Wings with the marginal areolets complete: mandibles rather short, denticu-

exserted: antenne various. Larva cylindric, fleshy, apterous.

The insects of this family, as their name implies, are found in
wood, in which they appear to perforate cylindrical holes, like those
of the following; but the larve, &c. have not hitherto been de-

scribed, I believe.

XIPHYDRIID.E.—XYELA. 109

There are two genera only found in Britain, which may be thus
distinguished by external characters :—

Anienne fracte, art? 3-tio valdé elongato; tidiis posticis in medio
spinosis : ¥ : : 0 - dl. XYELA.
haud fracte ; ¢ibiis omnibus in medio inermibus : . o2, XIPHYDRIA.

Genus XXXI.—XYELA, Daiman.

Antenne rather long, 12-jointed, slightly elbowed beyond the 3rd joint, the
basal joint robust, cylindric ; 2nd short, obconic ; 3rd also robust, cylindric,
equal in length to the remaining joints, all of which are minute, the terminal
one being least: palpi unequal, maxillary very long, 4-jointed, the terminal
one half as long as the 3rd, flat: mandibles 3-dentate: head transverse, de-=
pressed : ocelli 3: collar short: wings short, broad, especially the posterior 5
auterior with 3 marginal areoilets, the 1st small, at the base of the stigma,
which is large, the other 2 placed obliquely beyond the stigma ; and 3 sub-
marginal ones, the 1st receiving 1 recurrent nervure, the 2nd 2, and the 3rd
being smaller, and extending nearly to the apex; disc and posterior wings
distinctly areolated: abdomen short, subcylindric, elongate at the apex in
the males, rather acute, and furnished with a long sword-shaped ovipositor
in the females: legs simple, placed far behind: ¢ébie with a spur at the
apex, the 4 posterior ones with a spur in the middle, and the hinder pair
with 2 bristles on the outer edge.

The very singular structure of the antennee of this genus is amply
sufficient to distinguish it from Xiphydria, from which it also greatly
differs in its ample wings, all of which have numerous areolets, the
anterior with 3 marginal and 3 submarginal ones ; the maxillary
palpi are long and slender; the tibiae armed with spurs; the ovipo-

sitor in the females very different, &c.

Xy. pusilla. Dalman.—Curtis, v. i. pl. 30.—Steph. Catal. 341. No. 3993.

Head and thorax brown-black ; clypeus and orbits luteous ; the disc of the
thorax with 2 luteous spots; abdomen with a yellow dot on the back of the
2 basal segments, the remainder with the margins pale, except the last,
which is entirely pale luteous ; legs pale, with the femora dusky ; antennee
fuscous, testaceous beneath ; wings hyaline, rather tawny, with the nervures
and stigma darker. Ovipositor as long as the abdomen, and pale ochreous.
Found at the end of June near Hertford, in the vicinity of a fir

grove; also taken in Norfolk upon umbelliferous plants in July, and

in Worcestershire and in the south of Scotland.

110 MANDIBULATA.—HYMENOPTERA.

Genus XX XII.—XIPHYDRIA, Latreille.

Antenne setaceous, consisting of about 17 joints, of which the basal one is
longest and slightly thickened, the 2nd minute subglobose, 3rd nearly as
long as the 1st, but slender, remainder gradually decreasing in length, and
the terminal ones very indistinctly articulated: palpi short, maxillary
slender, the 3 terminal joints of equal length, the last obliquely truncate and
acuminate: mandibles bidentate: head large, orbiculate, petiolated, forehead
elevated: ocelli 3: thorax broader than the head: collar elongate: wings
rather Jong ; anterior with 2 subequal marginal areolets, and 4 submarginal
ones, the 1st subquadrate, 3 following gradually increasing in width, the 2nd
receiving 1, and the 3rd 2, recurrent nervures : abdomen somewhat cylindric,
flat and rounded at the apex in the males, convex above and subulated in
the females, and furnished with an exserted, compressed, subserrated ovi-
positor: legs slender, compressed ; anterior tibie shortest, all armed with 2
spurs at the apex, but without any in the middle.

Compared with the foregoing genus, these insects are gigantic,
but, like all xylophagous species, they are subject to very great
variations in size: without noticing other characters of distinction
between them, they may be known from the Xyele by having 2
distinct marginal, and 4 complete submarginal areolets in the anterior
wings: they are generally found in the vicinity of willows, flying by
day.

Si. Camelus. Linné.—Xi. Camelus. Steph. Catal. 342. No. 3994.

Black, shining: head glabrous, forehead rough, with an oblong white streak
on each side of the crown, a small one behind each eye, and a smaller one at
the base of each mandible ; thorax rough, with a minute white dot at the
insertion of the wings on each side; abdomen with the 2 basal segments
finely punctured, the 6 following glabrous and shining, each with a triangular
white dot on both sides, the 1st and 3rd being smallest, terminal segment
rough and immaculate ; legs testaceous, with the apex of the tarsi black ;
wings hyaline, slightly clouded towards the apex ; antenne sometimes with
the basal joints ferruginous.

Male with the white dots on the abdomen smaller and equal ; but they vary in
number in both sexes, and the insects also vary greatly in size.

Less abundant than the next, and I believe not found in the southern
part of the kingdom: it appears to be plentiful near Newcastle-on-
Tyne, as I am informed by Mr. Wailes, who first kindly supplied me
with specimens; and also taken in the south of Scotland, about the

end of June.

Black, shining: forehead rough, with 2 oblong white streaks on the crown, 2
small ones behind the eye, and 4 beneath; thorax rough, with a white
crescent on each side before the wings ; abdomen with the 2 basal segments
rough with punctures, immaculate, the 6 following glabrous, shining dull
red, witha white dot on both sides of each segment, the terminal one largest ;
legs ferruginous, the tibie white at the base ; tarsi with the basal joint pale,
the remainder brownish; wings hyaline, with fuscous nervures, and a little
clouded with fuscous at the tips. Ovipositor red, with black sheaths.

Male with only 1 or 2segments of the abdomen red: both sexes vary consider-
ably in size, and the number of white dots on the sides of the abdomen
varies also.

Taken in marshy places, where willows abound, in the vicinity of

London, as in Battersea and Rotherhithe fields; near Fulham; also

in the New Forest and in Norfolk, from May to July: not un-

common.

Famity I1J.—_UROCERIDA, Leach.

Wings with distinct marginal areolets : mandibles short: labium entire, not
lobate: maxillary palpi long and 5-jointed, or short, with 1 or 2 joints ;
labial short, with from 1 to 4 joints : ovipositor filiform, inclosed in a groove
beneath the abdemen, or arising from a deep cleft beneath the 6th segment,
and extending backwards considerably beyond the apex of the abdomen:
antenne various.

The insects of this family are also xylophagous, but they differ too
much in structure to be associated with the foregomg, as may be
observed by the characters above given: like those insects they differ
considerably in size ; the larger species of the group are very
destructive, and at times commit sad havock amongst timber trees,
especially those of the tir kind, but, happily for the proprietors, they
are comparatively rare in this country, occurring only in a few
distinct localities, but in them they are sometimes far too numerous:
they are very active and lively, and fly with rapidity, making a loud
humming noise.

In Britain 2 genera only have hitherto been discriminated, but the
genus Sirex offers such considerable variations in the structure of its
trophi, &c. as may probably warrant its subdivision into more : —the
2 already distinguished may be thus known :—

Genus XXXIITI.—ORYSSUS, Latreille.

Antenne filiform, 11-jointed in the males, basal joint large, 2nd joint short,
obconic; 3rd also obconic, longer; 4th and remainder nearly equal in
length, the terminal one acute; 10-jointed in the female, the basal joint
robust, subglobose, 2nd short, 3rd elongate, subclavate, 4th and 5th short,
6th longer than either of the others, 2 following each about as long as the
3rd, 9th rather longer and broader, obliquely truncate, 10th small, slender.
palpi very unequal, maxillary 5-jointed, labial 3-jointed : mandibles rounded,
not dentate: head large, orbicular: ocelli3: thorax rather narrower than
the head: wings short; anterior with 1 marginal and 2 submarginal
areolets, the last imperfect : abdomen broad, slightly clavate, with the ov7-
posttor concealed in a groove beneath: legs rather short: ¢ibie furnished
with a pair of spurs at the apex, anterior in the female with a deep suture :
tarst 5-jointed, anterior in the female 3-jointed.

The singular antennee of these insects, united to the paucity of the
number of articulations, the single marginal areolet in the anterior
wings, the great length of the maxillary palpi, which are distinctly
5-joited, the simple rounded mandibles, &c. sufficiently indicate the
difference of this fine genus from the following.

Or. coronatus. Latreille.—Steph. Catal. 342. No. 3996.—Curtis, v. x. pl. 460.

Head black, slightly shining, with a white line on each side from the eyes to
the insertion of the antenne ; eyes fuscous; thorax black, rough, immacu-
late; abdomen with the 2 basal segments the same, the remainder smooth
and rusty-red, the extreme tip blackish beneath; femora black, with a spot
at the apex, and the base of the tibie white, the apex of the latter and the
whole of the anterior black, the intermediate and posterior ferruginous
within ; tarsi lutescent; wings hyaline, the anterior with an undefined
fuscous fascia towards the apex, in which on the costa, adjoining the
stigma, which is pitchy-black, is a clear spot; nervures pitchy ; antennz
with the base and apex black, the intermediate joints white above.

T'wo examples only of this fine insect have hitherto, so far as I am
aware, been taken in Britain; the first was caught in July, 1817, at
Darenth wood, by Dr. Leach, while in company with me, on a col-
lecting excursion; the other was also taken subsequently in Devon-
shire, by the same distinguished naturalist.

URGCERIDE.—-SIRES. 1s:

Genus XX XIV.—SIREX, Linné.

Antenne filiform or setaceous, as long or longer than the thorax, articulations
varying from 17 to 25, generally most in the female ; the Ist and 3rd joints
longest, of equal length, the former robust, 2nd minute globose, 4th shorter
than the 3rd, the remainder very gradually diminishing in length: palpi
mequal, very short, maxillary ciliated and 2- or 1-jointed ; labial thrice as
long and more slender, very pilose, with 4, 3, or 2 joints, the terminal one
robust: mandibles thick, 3-dentate: head moderate, semiglobose: cyes
small: ocelli 3: thorax rather wider than the head, the anterior angle or
collar produced: wings with 2 marginal and 2 submarginal areolets:
abdomen long, cylindric, terminating in an elongate point, and in the female
with an elongate oviposttor arising from beneath the 6th segment, and
extending considerably beyond the apex of the abdominal appendage: legs
moderate ; posterior pair slender in the females, in the males with their tibiz
and tarsi much dilated. Larva soft, cylindric, with six legs, the terminal
segment rounded, and plicate, armed with a short spine: pupa folliculated.
As before alluded to, the insects of this conspicuous genus differ

considerably in parts (the trophi) that are usually considered as
being of great moment in the determination of genera, but there
appear so many preponderating external characters of similarity as
not to warrant the separation of the discordant species ; I shall there-
fore merely indicate their discrepancies from Klug. The larve feed
on the inner substance of fir trees, boring large cylindrical holes, and
committing sad havoc where they abound.

robust, silky, finely punctured and deep blue-black above and below ; the
appendage at the apex short and conical; ovipositor also blue-black 2
femora rusty-red, with a blue gloss at the base; tibie testaceous ; tarsi also
testaceous, with the terminal joint fuscous ; antenne black ; wings hyaline,
pale testaceous, with the limb dusky, the nervures, costa, and stigma ferru-
ginous, the last darkest.

Male blue-black, with the margins of the 3rd segment, and the whole of the
4th, 5th, 6th, and 7th red; the hinder tibie and tarsi dilated, compressed
and dark blue-black; the penultimate joint of the tarsi red.

Both sexes vary in having the femora sometimes entirely red, at others more
or less clouded with blue-black ; the tibie are occasionally clouded with the
same on the outer side; the number of joints in the antenne appears to be
variable, and the blue colour is frequently enlivened by tints of brightish
green.

Male varies with the 6 basal joints of the antenne bright red, the abdomen
rufous, with the 2 basal joints and a patch at the base of the 3rd blue-black,
the appendage only to the 9th also blue-black, legs as above.

This sex also varies in having the antennze totally black, and the abdomen,
with the exception of the 2 basal segments, bright red: this has been called
Si. nigricornis of Fabricius, which is an American insect, and from which it
differs in several particulars.

This beautiful and extremely variable insect is decidedly the most

common, at least in this country, of the genus; it occurs near Birch

from the circumstance of Donovan having misapplied the name to Pimpla

instigator.

Subdivision B. of the TkreBrantTIA embraces those insects which form the
genus Ichneumon of Linné, and may be considered as a sub-section by the
name

PUPOPHAGA, Latreille,

Which have, as stated in page 4, the abdomen united to the thorax by a
distinct peduncle.

This is a very extensive subdivision, and is again further divisible
into 2 distinct sections, and into several families, which I shall treat
of in the order given in my Catalogue, although probably not quite
natural, as the Ist of these appears to have but little affinity with the
preceding, and would rather seem to connect the Cynipide with the
Ichneumonidee, while the last (as Pimpla) are evidently allied to the
Uroceridee.

The Ist section upon which I shall treat contains the following
families, which may be thus cursorily distinguished ; premising that
the group itself may be generally recognized by the posterior wings
being furnished with distinct (frequently radiating) nervures—a
character scarcely found in the 2nd section, and never wanting

peculiarities as will almost remove it to the 2nd section.

Famiry IV.—EVANIIDA, Leach.

Antenne with 13 or 14 articulations, filiform, or very slightly attenuated :
mandibles denticulate : maxillary palpi filiform or setaceous, 6-jointed; labial
4-jointed : head vertical: ocelli 3: collar very short: thorax very convex:
metathorax shelving: abdomen inserted beneath the scutellum; short and
clavate, or elongate and somewhat linear: posterior tibie sometimes
clavate.

The insects included in this family vary much among themselves,
the 2 typical genera having the abdomen remarkably small in com-
parison with the great bulk of the trunk: it is oval, compressed, and
abruptly supported by a slender elongate peduncle, which is inserted
close to the base of the scutellum, whereas, in the other genus, the
abdomen is considerably elongate, and of a gradually clavate form,
inserted by its smaller end beneath the scutellum; the ovipositor of
the female is exserted, and the habit of the insect tends towards the
Glyptz, Xylonomi, &c. amongst the Ichneumonide, while the typical
forms resemble the Cynipidz.

Genus XX XVI.—BRACHYGASTER, Leach.

Antenne approximating, slightly thickened towards the apex, 13-jointed, basal
joint longest, a little shortest at the apex, 2nd minute, 3rd not much longer,
the remainder gradually diminishing in length: head subglobose, transverse
above: eyes not prominent: thorax glabrous: wings short, anterior with the
discoidal areolets and apical nervures obliterated: abdomen 3-articulate,

abdomen very short, conipressed, consisting of 4 segments, arising from an
elongate very distinct peduncle, which is inserted immediately below the
scutellum: ovipositor not exserted: wings moderate ; anterior with 2 or 3
distinct areolets on the disc, and the apical nervures conspicuous, with 1
marginal areolet: legs elongate: ¢ibi@ not clavate, with a pair of spurs at
the apex.

From Brachygaster these insects differ, as pointed out by Latreille, manifestly
by having the anterior wings furnished with distinct areolets on the disc,
and 1 large marginal one, besides having the nervures continued nearly to
the apex: the antenne are of a different form, and the proportions of the
joints dissimilar, as well as those of the palpi: the Evanie seem destined to
keep within bounds the true Blatte, and as I believe that genus of insects
not to be an aboriginal native, their parasites certainly cannot be; I there-
fore place the species (of both which I possess English examples) at the
foot of the page, in accordance with my usual plan.

pitchy, and the apex of the posterior femora and base of the tibie also red,
the rest of the tibie pitchy; thorax deeply punctured; abdomen glabrous
beneath ; wings fuscescent, with the stigma dark.

I have a pair of this species, which was taken, along with others now in the

compressed, inserted by a long slender peduncle below the scutellum: ovi-

positor not exserted: legs moderate: tibie not clavate, with a pair of spurs

at the apex.

These minute insects, at a first glance, resemble some of the Chal-
cidee, from the paucity of nervures in their anterior wings, their short
antennz, and petiolated abdomen: from the true Evaniee they may
be known by the antennz being faintly thickened towards the apex,
and by having the 3rd joint scarcely longer than the 2nd, as well as
the anterior wings being destitute of discoidal areolets : the indigenous
species are probably parasitic upon the insects of the genus Kctobius,
and as this last genus is rather numerous, there are probably many
species, but, as yet, 2 only have been detected.

Mr. Haliday, in the place quoted, suspects this genus is referrible
to this family: as I have never seen the insect, I shall follow his
opinion, as from the description it evidently differs much from the
Braconide. Mr. Shuckard informs me it is the Paxyloma De Breb.

Genus XX XVITI.—FOINUS, Fabricius.

Antenne approximating, short, straight, filiform, 15-jointed in the males, 14-
jointed in the females ; basal joint short, ovate, rather stoutest ; 2nd smallest,
minute; 4th longer than the 3rd, 5th almost as long, the remainder gra-
dually decreasing in length to the apical one, which is somewhat longer than
the 4th: palpi rather unequal, filiform : head orbicular, attached by a distinct
neck: thorax narrow, compressed : wings rather short ; anterior with 1 large
marginal areolet, 2 large submarginal ones, and 3 small irregular ones on
the disc: abdomen elongate, compressed, narrow, clavate, very slender at
the base: ovipositor exserted, long: legs short, posterior longest, their tzbie
clavate, with a single spine at the apex, the anterior with one towards the
apex: t¢arst moderate.

The long clavate abdomen of both sexes of this genus, and their
clavate hinder tibiz, combined with the exserted ovipositor of the
females, the dissimilarity in the neuration of the wings, &c. sufficiently
indicate their distinction from the 3 preceding genera. ‘These insects
frequent sandy situations, and are probably parasitic upon Pompili
and other Spheegiform insects, Stelis pheeoptera, &c.

ovipositor about as long as the rest of the insect, reddish ; legs black, the 4
anterior tibie whitish at the base, the hinder pair with a white ring near the
base, and on the basal joint of the tarsi; wings hyaline, white.

The 4th segment of the abdomen is sometimes dusky, or fuscous above ; and
the male wants the white ring on the posterior tarsi.

minutely punctured, and the latter with coarse punctures; abdomen with
an indistinct reddish fascia on the 2nd, 3rd, and 4th segments, most distinct
on the sides; ovipositor less than half the length of the abdomen ; legs dull
or pitchy-black, with a pale ring at or near the base of the tibie ; tarsi
slightly rufescent.

* The arrival at this point of my subject allows me the opportunity of
introducing some remarks upon the general nature of these Illustrations. It
will be seen, upon a reference to the Introduction in my Ist vol., that I there
state it to be my intention to introduce into these pages all the species that
had previously been recorded as British, placing such as appeared, from my
experience, to have been improperly, or accidentally, introduced at the bottom
of the page; but, with regard to the group now under consideration, I must
depart from that resolution, as, for some untenable reason, all the species
contained in Gravenhorst’s Ichneumonologia Europea were for a period of at
least 2 years given to the world as indigenous; I shall therefore merely intro-
duce those species only which I have ascertained, with considerable labour, to
be really found in this country, following Gravenhorst’s arrangement, with
one or two very trifling alterations; as, from the vastness of modern entomo-
logical science—my own collection now verging upon 100,000 specimens—I
am not ashamed to acknowledge my ignorance of this and some other groups
that have within these few years been extensively investigated by others; it

ne MANDIBULATA.—HYMENOPTERA.

palpi filiform, maxillary usually 5-jointed : mandibles bidentate, or notched :
anterior wings with the first submarginal areolet very large, the 2 discoidal
ones situated longitudinally one above the other, the outer one as broad at
its base as the apex of the external humeral one: ovzposztor either concealed,
or more or less exserted, often above twice the length of the insect, slender,
setaceous. Larve elongate, fleshy, subsisting upon the fatty portions of other
living larve—chiefly of the Lepidoptera—in which they frequently change
_ to pupa, these last are sometimes enveloped in a tough glossy silken cocoon,
or in one of an open texture.
The insects contained in this very extensive and difficult family
appear destined to keep within due bounds the larve of other

insects, especially those of the Lepidoptera, upon which they subsist

would therefore be presumptuous in me to venture upon breaking up the labours
of Gravenhorst, &c. without the probability of improving them ; but, so far as
the mere ascertainment of the indigenous species allows, I conceive the object
of my investigations will be fully answered in these pages, as I have been
unremitting in my endeavours to detect as many as possible, though, from the
immense extent of, and great difficulty attendant upon many parts of, the
subject, I cannot expect to make other than an approximation to the truth.
With regard to another matter, I must again refer to the Introduction to my Ist
vol.,wherein it is observed “that I have endeavoured to steer the middle course,
and to give such distinctive characters as will apparently separate from its
affinities any particular insect that has come under my observation,” “as
minute descriptions are the province of the monographer alone, and are ill
calculated for a work of this nature ;” and shall merely remark, with reference
to the additional observations in the Entomological Magazine, vol. iii. p. 170,
to which, or other criticisms, I have doubtless a right to reply—that although
J never attempted to compare my labours with those of Kirby and Gy!lenhal,
therein referred to, it may be stated that the descriptions of the latter author
occupy upon an average above a page each—viz. 2,190 species in 2,630
pages—and those of the former, with their accompanying notes, from
1 to 12 pages—210 species in 377 pages, and a volume upon the sections ;
—hence the length of time alluded to by me in the postscript to my
5th volume, as required for the completion of this work upon a similar
plan (exclusively of the additional expense): and although in that post-
script I alluded to the fact of Mr. Shuckard’s inability to ascertain certain
‘species of Andrena, &c. by means of the “‘ Monographia Apum Anglie,” a
position corrected by me in my vol. vi. p. 19, it may be added, that those insects
are of a peculiar habit, and speedily alter by age during life, and hence the
same species assumes so many phases, that it becomes almost impossible, from
the description of a single example of a long-excluded individual, however
accurate—and the accuracy of Mr. Kirby “is beyond all praise,’—to give a
definition that shall correspond with a recently disclosed one, a cause that does

vitality left to enable them to change to pupz ; though sometimes

not operate in other families: how far, therefore, the calculations made in
regard to my unpublished labours depend upon similar carcumstances the candid
entomologist will be best able to appreciate, especially as it is assumed that
because the descriptions are not printed, they cannot he written ! ! ! And with
respect to the mere assertion that the result of an investigation of Gyllenhal’s
descriptions is constantly satisfactory, I presume that my innate stupidity, or
want of tact, prevents me from profiting in that manner, as J have been unable
to determine satisfactorily numerous species described by him, as a reference
to the 2nd edition of my Nomenclature will render manifest! These critiques,
combined with the simultaneous actions of the writer, aroused my sensibility '!
I shall conclude this note by adding that every person has clearly an unques-
tionable right, to a certain extent, of availing himself of the published labours
of his predecessors. I have therefore, as also stated in my Introduction and
elsewhere, openly taken advantage thereof, and have as constantly referred to
the authors—either through the medium of my Catalogue or of these pages—
where any information may have been thus obtained ; and in drawing up the
descriptions either of the genera or of the species, I have (where practicable)
invariably taken the best previous description, and have either endeavoured to
extract its principal points, when too diffuse, or to augment them, when too
scanty, so as to correspond with the insects in my cabinets; a proceeding
equally adopted by those persons who affect pure originality, as may be seen
by a comparison of their labours with those of their predecessors. These
remarks are elicited in consequence of a recent reiteration of the charge against
me for not acknowledging particular sources whence I may have obtained
‘information,+ as a retort for previous observations of mine, but the point is
widely different, as my remarks apply solely to such writers as obtain by
artifice the unpublished notes of others, and subsequently incorporate them with,
and claim them as, their own. I complain not of the profuse employment of the
localities discovered by me, and published in these pages, or of the extraction of
any other information therefrom, whether taken from a purchased copy, or
from one presented to a public library !!

+ To prevent the reader from being misled by an erroneous statement, it is
necessary that I should notice a remark by Mr. Curtis, under his genus (559)
Nascra, who states “that Hiibner divides the species (included under
Margaritia) into 16 genera, to which Mr. Stephens has added another ;” and
upon these false data proceeds to add a lengthened tirade about the puerility
of forming genera upon trifling characters. New, upon referring to Hiibuer, it

ment of the poet, that—

“¢ Great fleas and little fleas have smaller fleas to bite em,

«¢ The smaller fleas have lesser fleas, so on ad infinitum.”

The British species, which amount to several hundreds, are
divisible into numerous genera, but, for reasons stated in the note, I
shall follow Gravenhorst, and commence by an abridgment of his
tabular view of the mdigenous genera, with a few slight additions.

will be found that the insects alluded to are divided by him into only 12
genera (vide vol. iv. p. 417) 10 of which I have condensed into 1, viz. Marga-
ritia!! from one section of which Mr. Curtis has removed one of tne species
as a genus (Nascia) because its maxille are rather short!!! whereas ina
previous folio (555) he there unites discordant groups, in one portion of which
the maxille are short, and in the other “long and perfect,” exclusively of
differing in other respects, as well as in outline, which he, in folios 207, &c.,
states to be a good character in the discrimination of Lepidopterous genera!!!
I will only add, that so far from coinciding with Hubner, I have (as may be
readily seen upon a reference to the 4th vol. of Haustellata throughout, and
to the forthcoming 2nd part of my Nomenclature) in very numerous instances
reduced his genera to mere subdivisions, not employing them as genera, as
Mr. Curtis so disingenuously infers ! !

With these observations, referring also to what I have stated in the Appendix
to the 4th vol. above referred to, I close all further notice of the numerous
attacks that have or may be made regarding these Illustrations, hoping, from
the progress I have already made, by unwearied application, and the continued
blessing of good health, to bring them to a conclusion by this day twelvemonths,
without designedly abbreviating one tittle for the purpose of compressing them
within “ an inconvenient length” !

rouga and opaque, supported by a rather long, linear peduncle, having an

obtuse angle in its middle: apex of the abdomen rather acute: ovipositor

concealed, or merely exposed at the apex: wings moderate, the cellule* for

the most part 5-angular, rarely 3-angular, or pyramidal, or somewhat

4-angular: legs moderate.

Of this fine genus, which embraces many of the more conspicuous
insects of the family, above 200 species appear to occur in Britain :
_the principal characters of distinction, as pointed out by Graven-
horst, consist in the abdomen being oblong or subovate, with its first
segment somewhat globulous and rough, the peduncle long, linear,
and bent; the cellule (or second submarginal areolet) tending to 5-
angular; the antennz and legs of moderate length ; and the ovipo-
‘sitor hidden, or but very slightly exposed.

* Although in p. 122 I stated that, in proceeding with the insects of this
family, I should not materially depart from Gravenhorst’s arrangement, I must
here, however, necessarily do so, since that laborious writer appears, in nume-
rous instances, to have separated the sexes from each other, and especially so
in those insects which he has placed in this and the following sections ; to
which I shall more particularly refer when treating of them. I regret my
present inability to investigate this point again practically, but I trust that
after the conclusion of these Illustrations, in accordance with the proposed
plan, to do so in the interim of preparing the 2 supplementary volumes, that
may probably be added a few years hence, in order to correct the unavoidable
errors I may have committed in so vast a field, as well as to add such novelties
as may have been then discovered.

Genus XL.—ISCHNUS, Gravenhorst.

Antenne generally slender, porrect, but rarely curved in the males, usually so

The genus Ischnus, or at least British species thereof, may be
known. by their great resemblance to those of the preceding genus,
combined with the length and slenderness of the antennz and legs,
and also of the abdomen, this last being in general ornamented with
divers coloured rings, and its basal segment being smooth, instead of
rugged, as in Ichneumon.

ICHNEUMONID £.—STILPNUS. 209

thorax rather gibbous: scutellum convex: abdomen depressed, very smooth,

and glossy, somewhat orbiculate in the females, and as wide as the thorax ;

the basal segment linear, narrower than the remainder, its anterior portion
rather broader than the peduncle, which has 2 lateral tubercles placed

before the middle: ovipositor scarcely exserted: wings ample; cellule 5-

angular, the outer nervure wanting, and thus rendering the cellule open,

and from its hinder angle arises the mere rudiment of the lower nervure:
legs slender, short. _

This genus, which appears to be closely allied to Hemiteles, may
be instantly recognized from the other genera of this family by
having a 5-angled cellule, the outer nervure of which is wanting, so
as to render the cellule open; the nervure of the inferior angle is
also wanting, so that the hinder portion of the hinder wing is nerve-
less.

ovate, rather broader than the thorax, the basal segment thrice as wide as
the peduncle; ovipositor scarcely exserted: wings narrow, rather longer
than the thorax ; cellule wanting: legs moderate, femora slightly thickened.
This singular genus may be instantly recognized by the brevity of

_its wings, combined with the form of its abdomen, and the shortness

-and stoutness of its legs.

subovate, with the basal segment somewhat convex and smooth anteriorly,

the peduncle very slender: /egs slender, long, sometimes a little abbreviated,
and with the femora, especially the hinder one, thickened.

Known from Typhon by having the abdomen oblong or somewhat
ovate, with the basal segment smooth and rather convex anteriorly,
and supported by a very slender peduncle; the legs and antennz
more or less elongate and slender: some of the species are very
closely allied to those of the following genus, and are to be discrimi-
nated with great difficulty : there is, nevertheless, a certain degree of
diversity in habit between them, by which a practised eye can readily
distinguish them.

§ I. Scutellum and abdomen black, the extreme margins of the segments of the

* IT am fully aware of the existence of other species of this genus; but,
unfortunately, circumstances oblige me to remain silent respecting them :—
having recently selected nearly all the unascertained and nondescript species
thereof from my cabinets, and placed them on a setting-board in a closet for
examination and description, the greater portion of them were so sadly muti-
lated by Blattze during the only night they were so exposed, as to render their
investigation unsatisfactory: | hope, however, to be enabied to ascertain some
of them in time for the Appendix, to which I must beg the reader to refer.

I may here take the opportunity of remarking, that although in very nume-
yous instances Gravenhorst has drawn up his descriptions from single specimens

ICHNEUMONID£.—TRYFHON. 931

Gexus XLV.—TRYPHON, Fallen.

Antenne slender or moderate, either as long as, or shorter than, the body, with
the apex more or less curved, in rare instances a little thickened in the
middle: head generally the width of the thorax, or rather narrower, rarely
broader, in 2 instances with a frontal horn: eyes ovate, or a little orbiculate,
more or less prominent: thorax gibbous, or somewhat globose: scutellum
convex, 3-angular, with the apex obtuse: wings moderate ; cellule 3-angular,
or suborbiculate, sometimes minute, and occasionally wanting; rarely 5-
angular; the inner nervure of the exterior cubital areolet sometimes pro-
ducing the rudiment of the divisional nervure, which forms so prominent a
character in the Ichneumones adsciti: abdomen subsessile or slightly petiolated,
rarely sessile, oblong, or a trifle lanceolated, or subclavate ; the basal segment
channelled, the lateral tubercles generally placed beyond the middle ; in the
females the apex of the abdomen is slightly thickened, and at times a little
compressed: ovipositor very short, and slightly exserted ; legs mostly short
or moderate; in a few instances rather elongate and slender; in others
short, and with the femora thickened.

Of all the genera of Ichneumonidz, none, perhaps, is composed of
more dissimilar subjects, so that it becomes extremely difficult to
draw the line of demarcation between many of them and those of
allied genera: one set of species is closely allied to the genus Bassus,
others to Mesoleptus, some again to Phygadeuon, and others to
Stilbonota; in fact, the genus is, apparently, a magazine for placing
all strange species that will not readily assimilate elsewhere: from
amongst these discordant insects we are informed, by Mr. Curtis,
that the genus Cteniscus has been formed by Mr. Haliday, to
embrace I'v. 6-lituratus and its congeners: another genus might be,
with equal propriety, formed of Tr. elegantulus, a third from Tr.
insolens, &c., and will doubtless be eventually formed. —

§ I. Scutellum and abdomen black, with the extreme edges of the segments
frequently pale.
Sp. 1. niger. Miger, fucie et tibiarum posticarum medio albo-testaceis, pedibus
anterioribus rufis, trochanteribus stramineis, covis nigris. (Long. corp. 4g—

only, I have been enabled to verify his species, in many Cases, as such, from
having been nearly as great a length of time (above 25 years) in accumulating
indigenous species, as the learned Professor was in collecting European ones ;
but the subject is of so great an extent, that although I may give a tolerable
epitome of the numbers found in this country, much remains to be performed.

Genus XLVI.—EXOCHUS, Gravenhorst.

Antenne short, straight, somewhat filiform, composed of about 27 articu-
lations ; head rather short, transverse, face more or less protuberant below
the antenne; eyes ovate, or somewhat orbicular: thorax cylindric, or
slightly gibbous: scutellum flattish, triangular: wings moderate, or smallish ;
cellule none, or small, 3-angular, and petiolated : abdomen somewhat sessile,
convex, oblong-cylindric, sometimes a little thickened, shining, smooth, the
basal segment slightly channelled, its lateral tubercles placed beyond the
middle: ovipositor generally concealed: legs short, robust, femora and ¢ibie
a little compressed.

This genus, as indicated by Gravenhorst, differs chiefly from the

preceding by having the legs short and thick, the face protuberant—
whence its name—and the abdomen somewhat sessile, oblong-cylin-
dric ; to which may be added the comparative brevity of the wings
and the smallness of stature: the insects are generally found amongst
grass, or on umbelliferous plants, during the summer and com-

mencement of autumn.

Genus XLVII.—SCOLOBATES, Gravenhorst.

Antenne porrect, slender and curved at the apex: head transverse, a little
swollen in front, and deeply excavated behind: eyes ovate: thorax gibbous:
scutellum 3-angular, somewhat gibbous: wings moderate, cellule wanting:
abdomen somewhat sessile, oblong-ovate, the apex slightly compressed, the
1st segment sensibly narrowed towards the base, the lateral tubercles placed
before the middle; ovipositor scarcely exserted; lJegs various, 4 anterior
moderate, posterior pair elongate, tarsi either simple or thickened, as in the
Anomala.

These insects principally differ from the preceding by having the
hinder pair of legs elongated, and their tarsi thickened, as in the
genus Anomalon; the wings moderate, destitute of a cellule, the
abdomen somewhat sessile, the Ist segment narrowed towards the
base, and its lateral tubercles placed before the middle :—there are
probably more indigenous species of this genus than I have indicated,
as Mr. Shuckard informs me has seen 3 or 4, unnamed, placed in
some cabinets.

Black: head tawny-rusty, with the crown, occiput, sometimes a dot beneath
the antenne, and 2 lines on the face black ; antennee rusty, dusky towards
the base, the Ist joint black above, yellowish beneath ; abdomen a little de-
pressed, slightly channelled, black, the apex red, 2nd and 3rd red, remainder
black, with the base of the 4th slightly reddish ; anterior legs testaceous-
red, coxe, trochanters, and extreme base of the middle femora black,
posterior with the femora red, the tibie reddish at the base, the apex
blackish ; tarsi rather thick and black ; wings rather smoky-hyaline.
Taken very rarely, in July and August, within the metropolitan

district.
Genus XLVIII.—TROGUS, Panzer.

Antenne moderate, about half the length of the body, setaceous, porrect, or
curved at the apex, sometimes faintly serrated within : head short, transverse,
a little narrowed towards the collar: eyes oval: thorax gibbous: scutellum
somewhat quadrate, more or less gibbous: wings rather ample, in the
British species transparent; cellule 3-angular or 5-angular, sessile, or
somewhat petiolated: abdomen petiolated, convex, oblong, or oblong-ovate,
the anterior portion of the Ist segment somewhat gibbous, generally with 2
elevated lines, peduncle slender, linear and channelled : ovipositor concealed:
legs moderate, femora and tibie rather stoutish.
The splendid insects, contained in this fine genus, may be distin-
guished not only by their great bulk, but chiefly by having the
scutellum very convex, the abdomen distinctly pedunculated and
convex, and the head transverse; their larvee usually prey upon
those of the Sphingidee, or of the larger Bombycide and Noctuide :
from the splendid series I possess of these insects, and from their
habit, &c. I am induced to consider that Gravenhorst has confused at
least 3 distinct species together, as I have attempted to indicate.

patch ; legs slenderish, black, 4 anterior of the male ochreous-white beneath,
the hinder trochanters and tibize the same, the tip of the latter more or less
black; of the female the tibize and tarsi are fuscescent, with the base of the
femora sometimes reddish ; wings smoky-hyaline ; cellule 3-angular, faintly
petiolated.

rally testaceous, anterior coxe pale, posterior black, with the tip testaceous ;

wings pale tawny-hyaline; cellule 3-angular.

An extremely variable species: in some examples the thorax is nearly black,

black streaks ; the abdomen is occasionally wholly testaceous, and at times
has 1 or more of the terminal segments black at the base: the legs also vary ;
in some examples all the coxe are pale, in others 1, or more, pair is spotted
with black ; the hinder femora are sometimes immaculate, at others spotted,
&c.

This and the preceding species closely resemble true Ichneumons, and were
it not for their comparatively gigantic bulk, much elevated scutellum,
&c. I should have placed them in that genus 3 they exceed by 2 lines the
largest species of Ichneumon described by Gravenhorst, excepting Ic. lami-
natorius, which belongs toa section with black abdomen.

I possess one example from Francillon’s collection, a 2nd from

_ Marsham’s, and a 3rd from Haworth’s; and Mr. Newman has 1

taken by himself at Birch wood.

Genus XLIX.—ALOMYA, Panzer.

Antenne of the male setaceous, porrect ; of the female short, stout, filiform,
convoluted, with about 32 joints; head small, somewhat globose, seen from
above rather quadrate, the face with a slightly elevated tubercle: eyes oval:
thorax somewhat cylindric-globose: scutellum 3-angular, flattish: wings
moderate ; cellule 5-angular: abdomen. petiolated, convex, elongate, a little
dilated at the apex in the male, more so in the female : ovipositor concealed :
legs moderate, short, and rather thickened in the female: sexes dissimilarly
coloured.

The chief characteristics of Alomya consist in the abdomen being
convex and petiolated, the head small and globose, and the cellule
large and 5-angular, not 3-angular, as stated in p. 126, from
Gravenhorst: the sexes are very dissimilar, and in the female
the wings are considerably abbreviated: the species are extremely
prone to vary, and I am of opinion that all the supposed indigenous
ones may be referrible to one species, notwithstanding their great
dissimilarity.

segment black, with its apex always, and sometimes the base, red, 2nd to
4th generally dull red, the last sometimes with an obscure dorsal spot, 5th
red with the margin black, or black with the base and sides red, but rarely
wholly red; 6th rarely with the sides red ; legs tawny, with the coxez and
trochanters black, 4 anterior femora tawny, with the base more or less black,
rarely entirely black or tawny; posterior femora black, with the tibie
yellow or testaceous, the apex at times fuscous: in the female the legs are
rather of a darker hue, but in both sexes they vary in colour; wings some-
what hyaline.

it occurs within the metropolitan district, also in the New Forest, in
Devonshire, Norfolk, Salop, near Dover, &c.

Black, silky: legs with the coxe and trochanters black, anterior femora tawny,
sometimes black at the base, middle entirely tawny or totally black, or tawny
with the base black, posterior black; 4 anterior tibie tawny, middle occa-

and apex blackish or fuscous, with the opposite side rusty before the tip ;
tarsi tawny, anterior sometimes red, middle occasionally fuscescent, and
posterior at times fuscous; wings smoky-hyaline, stigma tawny ; cellule

Of this conspicuous insect the female appears to be unknown,
notwithstanding the species occurs throughout the country, and not
uncommonly : it is found in various places throughout the metropo-
litan district; also in the New Forest, in Devonshire, Salop, the

vicinity of Edinburgh, &c. in June and July.

ICHNEUMONID£.—HOPLISMENUS. B75

Genus L.—HOPLISMENUS, Gravenhorst.

2 elevated longitudinal lines, continued on the peduncle, which is linear and
rather long : ovzpositor a little exserted, short: legs rather slender.
Hoplismenus, as the name implies, embraces several species which

have the metathorax armed with 2 rather elongate acute spines, or

Genus LI.—CRYPTUS, Fabricius.

Antenne in general long, slender, porrect in the males, more or less curved in
the females, sometimes a little thickened and short ; head short, transverse,
rather narrower than the thorax, and narrowed towards the neck : eyes ovate,
more or less prominent: thoraa somewhat gibbous, rarely cylindric: scu-
tellum more or less convex, 3-angular, with the apex obtuse, or 4-angular :
wings moderate ; cellule 5- or 4-angular: abdomen petiolated, of the male
slender and narrow, of the female ovate or oblong, the basal segment smooth
and bent, and the apex at times faintly compressed: ovipositor exserted,
straight, sometimes as long as the body, for the most part about half the
length: legs rather slender and long, especially the posterior pair.

This rather extensive genus may be distinguished by having the
abdomen of the male narrow and elongate, of the female ovate or
oblong, the ovipositor considerably exserted, and in some species as
long as the abdomen; the basal segment is smooth and arched, the
peduncle rather long, the cellule 5- or somewhat 4-angular, and the
legs and antenne slender and long: the sexes are somewhat dissi-
milar, and, as usual in this difficult family, many of the species are
known of one sex only; in some cases only males, in others only
females, and occasionally one or cther of them in plenty, so that it
is not improbable that in some instances the sexes are more dissimilar
than suspected.

* For additional descriptions of some species of this genus and of the
following, contained in my collection, I must request the reader to refer to the
Appendix, to be given at the end of the present volume ; serious indisposition
having prevented me from duly investigating them in time to insert in their
respective places. It may be remembered that, including this sheet, I have
already described 843 Hymenoptera, of which 503 are Ichneumonide.

296 MANDIBULATA.—HYMENOPTERA,

Genus LII.—PHYGADEUON, Gravenhorst.

Antenne moderate, of the male porrect, longer and generally more slender
than in the females, in which sex they are curved or involuted ; in both
sexes the basal joints are more or less elongated: head short, transverse,
rather narrower than the thorax: eyes ovate, prominent: thoraw slightly
gibbous, or somewhat cylindric: mefathorax occasionally with spines: scu-
tellum more or less convex, 3-angular, with the apex a little obtuse: wings
moderate: cellule 5-angular, rarely with the outer nervure obsolete: abdomen
petiolated, of the male narrow, of the female oblong or ovate, slightly
convex, or a little depressed, the basal segment generally smooth, in some
species with 2 elevated lines, the petiole mostly obsoletely grooved: ovipo-
sitor exserted: Jegs moderate, sometimes a little thickened, at others rather
slender,

Of this genus Gravenhorst remarks that it differs from Cryptus
in having the antennee, legs, and ovipositor moderate, the cellule
5-angular, the abdomen of the female oblong or ovate, of the male
narrower, the lst segment with the petiole longer and narrower than
the anterior part, the surface smooth, &c.; to which may be added,
the length of the basal joints of the antenna, and these organs are
in general longer and rather more slender in the males than in the

females.
