Well and universally known as the Earwig is, comparatively 
few are acquainted with its oeconomy and singular structure, 
the dread entertained of these insects rendering them objects 
of aversion to most persons. Earwigs, having the power of 
flight, and coming out in the evening and night to feed upon 
vegetable substances, are exceedingly destructive to fruit and 

flowers, but it is not difficult to get rid of them by a little care 
and attention. In most instances amongst the insect tribes the 
female dies before her eggs hatch, but the parent Earwig lives 
to rear her young, and DeGeer says that, like the Hen, she 
broods over and apparently protects and feeds them. The 
young can run with alacrity, and resemble their parents, ex- 
cept in being smaller, paler in colour, and having no wings, 
and the abdominal appendages divaricate and are not horny. 

The wings of the Earwig are very delicate and pretty, re- 
sembling in some measure the Haliotis, or Ear-shell ; they are 
most curiously doubled, so that a small horny portion only 
projects beyond the elytra : the forceps are employed in fold- 
ing the wings, (they are therefore not wanted in the larvae or 
young ones,) and the little tubercles on the back and at the 
apex of the body probably assist in the operation. 

The Forficulidae found in this country have been divided 
into 4- genera, and the one before us into 3 species. 

1. auricularia Linn. — Panz. 87. 8. S • — neglecta Mars. ? . 

Male 7 lines long ; ochreous, head rufous, disc of thorax 
pitchy, abdomen castaneous, forceps much shorter than 
the abdomen and very much curved (fig. A^). Female 
a little smaller, forceps nearly straight, attenuated and 
finely serrated internally, except at the apex, which is 
curved (A ? ). 
Common, I believe, everywhere in England and Scotland in 

flowers, under stones, the bark of trees, &c. from April to Nov. 
Mr. Stephens gives the F. media of Marsham as a variety 

of this species, but from the characters in the Ent. Brit, there 

can be little doubt of its being either the male of Labia minor 

or another species of that genus. 

2. borealis Leach. — Curt. Brit. 560. S • 

Male 8 or 9 lines long ; ochreous, antennae lurid, except- 
ing the basal joint, head rufous, eyes black, disc of thorax 
pitchy, elytra lurid, the apex of the folded wings internally 
brown : abdomen castaneous, pitchy at the base and apex, 
forceps nearly as long as the abdomen, moderately curved, 
stout, castaneous, ochreous at the base, with a strong 
tooth on the inside of each towards the base, where there 
are smaller teeth. 
The specimens I take to be females have the forceps less 
curved than in F. auricularia. End of June to end of July, 
Scotland ; hedges, Glanville's Wootton, and in plenty under 
stones in Isle of Portland and Chesil Bank, Mr. Dale ; Yar- 
mouth, Mr. Paget. 

3. forcipata Step. I know nothing of this insect, but it is pro- 

bably a variety of the foregoing with longer forceps.

As volumes might be filled with the histories of the different 
species of Cockroaches, which are very numerous, and appear 
to be distributed over every part of the earth, I can only make 

a few remarks on the well known Cockroach, or Black-beetle 
as it is erroneously called, of our kitchens and houses, and 
must refer to DeGeer, Kirby and Spence, and other writers, 
who may be consulted with profit and amusement. 

The female lays an oval bag containing J 6 eggs ; and after 
having carried it about at the extremity of her body, by means 
of her forceps, until she has found a convenient place, she de- 
posits it: out of this horny bag the young Cockroaches issue, 
and rapidly increase in size until they arrive at the perfect 
state (having passed through that of the pupa), when the males 
become winged, but the females remain apterous. They are 
most active animals; and being nocturnal, very voracious, and 
omnivorous, they are very destructive in houses where they 
abound. Traps are employed for catching them, and common 
wafers that are coloured with red-lead strewed about before 
going to bed are said to be very effectual in destroying them, 
and probably sprinkling spirits of turpentine in their haunts 
would drive them away. It is said that some species of Sphex 
destroy them, and the Evania, a genus illustrated in our 257th 
plate, is one of its parasites. In Russia and Finland B. Orien- 
talis is a perfect pest, and although it seems to be naturalized 
everywhere, no one can determine whether it was originally a 
native of Asia or of South America, one of the many proofs of 
the necessity of speedily recording the geographical distri- 
bution of insects, which is intimately connected with the con- 
stants of nature proposed by Mr. Babbage. 

There are 1 1 species registered as inhabitants of England ; 
amongst them : 
4. B. gevmomc^L Lhvi. — Don. 10. 341. — Kirby SfSpe7ice, t. 2.

The Mole-cricket, Jarr-worm, Eve Churr, or Earth 

Order Orthoptera. Fam. Achetidae. 

Type of the Genus, Gryllus Gryllotalpa Linn. 
Gryllotalfa Ray, Lat., Curt. — AchetaF«&. — Gryllus (Acheta)Zeww. 
Antenna inserted before the eyes, shorter than the thorax, slightly 
setaceous, pubescent and composed of from 60 to 110 joints ; 
basal joint the stoutest, somewhat ovate, 2nd oblong, and larger 
than the following, which form very narrow rings at first, vary- 
ing a little in their length, but towards the apex they are longer 
and somewhat globose (1, the basal joints), 
Labrum exserted, flexible at the base, nearly orbicular and con- 
vex, the margin fringed with bristles (2). 

Mandibles not large, elongate-trigonate, a little curved at the 
apex, with a triangular tooth below on the inside, and another 
at the centre, with a third behind it, smaller in one mandible 
than in the other ; a longitudinal line of hairs down the outside 
and a few on the inside towards the base (3) . 
Maxilla elongated, terminated by a curved acute horny lobe with 
a very slender and acute tooth beneath, and a long curved pal- 
piform lobe outside, fleshy at the apex. Palpi long and 5 -jointed, 
2 basal joints transverse, the others long and equal, 3rd the stout- 
est, compressed, very convex outside, 4th and 5th subclavate, the 
latter terminated by a globose fleshy membrane (4). 
Mentum suborbicular. Lip elongated, terminated by a cordate 
fleshy lobe, from the base of which arise 2 stiffs parallel lobes, and 
on each side 2 stout rigid and pilose ones, all of the same length, 
(these appear to be additional Palpi) . Palpi inserted below them 
stout rigid and triarticulate, basal joint subglobose, 2nd and 3rd 
long of equal length, the former very pilose, the latter ovate and 
fleshy at the apex (5) . 
Head conical : eyes small, nearly lateral : ocelli 2, minute, placed be- 
tween the eyes. Thorax ovate, concave before. Elytra partially 
lying one over the other, the cells at the base more irregular in the 
male (9 (J), than in the female. "Wings ample, reticulated, longer 
than the body, folded longitudinally and lying upon the back when at 
rest. Abdomen large nearly alike in both sexes, with a setaceous 
pubescent and hairy process on each side the penultimate joint, as long 
as the antenna ; the apex divided into 3 short lobes in the female : 
ovipositor none. Legs, aiiterior very strong and dilated, posterior 
formedforleaping. Coxse large, especially the anterior (8 b). Thighs, 
anterior short and broad, with a sharp compressed tooth at the base 
(c) ; hinder pair long and incrassated. Tibiae of fore legs trigonate 
palmate, the apex divided into 4 strong teeth (d) ; posterior long, fur- 
nished with strong spines outside towards the apex. Tarsi triarticu- 
late, anterior compressed and trigonate, inserted on the side of the 
tibia, 2 first joints produced on the inside and acute, the \st large, 
'3rd small ovate (e) ; 1st and 3rd joints long and the 2nd globose in 
the other feet. Claws simple and small, straight and unequal in the 

G. vulgaris Lat. — Curt. Guide, Gen. 446. 1. — Gryllotalpa Linn. 

Velvety brown above, dark ochreous beneath ; margins of thorax tawny : 
elytra dull yellowish white, brown towards the base and costa, nervures 
dark brown : wings dirty white, with the costa, a longitudinal stripe be- 
low it, and many of the nervures bi'own : anterior tibiae and tarsi subcas- 
taneous, piceous at the apex. 

The Mole-cricket is one of the largest Insects inhabiting Britain ; its 
structure is wonderful and its oeconomy most interesting. In its perfect 
state it is capable of flight, and I suspect, from the resistance the thorax 
and elytra offer to water, that it is able to swim. Its fore paws are beau- 
tifully'adapted for burrowing in the ground, and their power is prodigious ; 
according toRoesel it commonly employs a force equal to the counterpoise 
of 2 or 3 pounds : there is a large tooth at the base of the anterior thighs 
which meets the interior margin of the tibia when bent back, and this re- 
ceiving and protecting the tarsus when in the act of digging or burrowing, 
altogether form a large toothed sort of hoe or shovel : they are able to 
run backward as well as forward with great facility in their burrows ; and 
to warn them of approaching danger in retrograding, as Professor Kidd has 
justly observed, they are furnished behind with 2 appendages similar to 
their antennse, but not jointed*. 

They live probably the year round, and are found in gardens, meadows, 
peat bogs, by the sides of ponds and streams, in dung-hills, pea and 
barley fields, &c., in most parts of England, particularly towards the 
south ; they feed on potatoes, and the roots of grass and corn, sometimes 
causing great mischief, it is said, to the crops in Germany. Dr. Kidd says 
they prefer raw meat, and will attack each other, when the victor devours 
the'flesh of the vanquished, but that they can live 9 or 10 months without 
food. I have kept a mole-cricket in a cage, but it has always managed 
to escape ; and so interesting are its habits and history, that I should re- 
commend those who amuse themselves by keeping mice and other animals 
to obtain some of the crickets, and they may be rewarded by some impor- 
tant and curious discoveries ; for this insect is supposed to be the " Will o' 
the wisp," the " ignis fatuus," about which so much has been said and so 
little proved, the phantom that has eluded the vigilance of the naturalist 
and the curious for ages ! They can emit a sound more shrill but softer 
than that of the frog, and Dr. Leach says the male sings in the evening by 
rubbing the elytra together. 

I am not aware that any one has been able to detect an external sexual 
character ; I am therefore happy in observing that after ascertaining the sexes 
by dissection, I discovered that the elytra are different. It is a female that 
I have represented flying, and on comparison it will be seen that the ely- 
tron (Jig. 9 $), which is the right-hand one of a male, has nervures very 
different to the other sex : the same peculiar structure is visible in this as 
in Acrydium (pi. 439-)> the inner edge having more the appearance of a 
costa than the outer one. The males seem to be uncommon; I have seen 
but 2, and in them the right-hand elytron lapped over the other, but in all 
the females it was the reverse. 

The Plant is Montia fontana (Water Blinks) .

phical Transactions, by J. Kidd, M.D., F.R.S., &c.

Li the Cabinets of Mr. Dale and the Author, 

Although the chirping of the Cricket is familiar to most per- 
sons, yet few comparatively are acquainted with its form. 
During the summer the heaths resound with the singing of 
the merry Field-Cricket ; and the incessant vibration of the 
House-Cricket is to some persons agreeable, whilst to others it 
is very annoying. Abundant as the former species must be, 
I have never seen it alive ; but of the latter I once saw in a 
bakehouse, countless multitudes in every stage of growth, 
from those that were just emerged from the egg to the perfect 
insects. And in a kitchen I have witnessed one running over 
the hot embers, immediately after the fire had been raked 
out, in so careless a manner that it was miraculous that its 
delicate wings were not scorched ; and his habitation beneath 
the grate must have been a very warm retreat. 

Crickets live underground, forming their burrows by means 
of their strong jaws; the labium assumes the form of max- 
illae, and behind it are a lip and 2 slender lobes, bearing in this 
respect as well as in the oviduct, a considerable analogy to 
the Tenthredinidae. 

The species found in this country are 

1. A. domestica Linn. — Do7i. 12. 409. — Panz. 88. 6 (^ 7. 

This insect lives through the year, and is very destruc- 
tive in houses, injuring wet linen, feeding on bread, 
&c. They may be taken like wasps by bottles filled 
with beer. 

2. A. campestris Lijin. — Don. 12. 432. — Sotio. Biii.Mis. tab. 

65.—Pafiz. 88. 8 4^ 9. 
Stewart says, " These insects live in holes, in dry soils, 
making a very curious subterraneous abode, with re- 
gular cells. They are solitary beings : sitting in 
the entrance of their caverns ; they chirp all night as 
well as day, from the middle of May to the middle 
of July; the noise they make is probably to allure 
the females, for the males alone make the chirping. 
They begin to appear and form their holes in March, 
and in August these holes are obliterated." I have 
been informed that in France, children decoy these 
insects from their burrows by inserting a fly attached 
to the end of a horse-hair. 

3. A. sylvestris Fab. — Curtis Brit. Ent. pi. 293. Jemale. 

Mr. Dale first discovered this insect amongst dead 
leaves in a gravel-pit, the middle of August, near 
Lyndhurst in the New Forest; and I have found the 
pupae on a dry bank at the same place, the begin- 
ning of June. 

4. A. itaica? Fab. — Pa?iz. 22. 17. — pellucens? Scop. 

A single specimen was taken in Norfolk in June, and 
is in Mr. Haworth's cabinet. 
The plant is Sisymbritim tenuifolium (Wall Rocket).

These insects are well known by the incessant chirping which 
they make in the evening and (.hiring the night ; a specimen 
of Acrida viridisshna that I kept, feeding it with flies, con- 
stantly began to sing at twilight ; and by placing a candle in 
the room, I could distinctly see that the sound was produced 
by chafiing the anterior margins of the elytra together when 
at rest. 

Greatly as this family has been divided since the days of 
Linnaeus, it is difficult to find characters that will embrace 
even the insects that are now included in this genus. The 
name Conocephaliis which Dr. Leach gave to these insects has 
been dropped, because it applies to an exotic group with co- 
nical heads that will not associate with any other ; and Mr. 
Kirby's name has been adopted, as it is intended to follow the 
views taken in the Zoological Journal by that learned author. 

Li giving the following arrangement, which I hope will be 
found useful, I beg to acknowledge my obligations to J. C. 
Dale, Esq., for his valuable information and assistance.

Mr. Dale informs me that A. Bingleii was first taken at 
Goodwin's Croft, near Christchurch, Hampshire, and given 
to the late Rev. W. Bingley. Mr. Dale's female was taken 
30th July, 1818, by the side of a barley field near Christ- 
church, and his male at the same place the 14th of August fol- 
lowing. This species has been confounded in the Entomolo- 
gical Transactions with A. verrncivora, a very fine species 
discovered near Rochester by Professor Henslow, the end of 
August ; it is employed by the Swedish peasantry to destroy 
warts, from which circumstance it receives its name. 

The plant figured is Carex pr^ecox (Vernal Carex).

Locust being the name used in Holy writ I have retained it 
in preference to that adopted by most authors. The history 
of these destructive insects is too well known to require repe- 
tition here ; it is evident from the dissection of the mouth that 
its mandibles are admirably adapted for cutting herbage, and 
its lips and maxillae for forming a large inclosure to retain its 
food whilst it is eating. 

Upwards of 20 species have been found in this countiy, which 
I shall enumerate, as many of the names in the Guide have 
been superseded by the appearance of Zettersted's and Char- 
pentier's works. 

1. Christii Curt. Brit. 608. ? . 

Pea-green, antennae sub ferruginous; an ochreous and purplish longitudinal 
line behind each eye, face with 2 lines down the middle and the man- 
dibles blue-black : thorax triangular behind, with a sharp convex carina : 
abdomen reddish-brown marbled with greenish-yellow : elytra more or 
less spotted, nervures reddish-brown, variegated with green towards the 
base : wings delicate yellow inclining to green, the apical portion more 
grey, nervures brown and piceous, reticulations ochreous : hinder legs 
pale green ; thighs blue internally beneath, with a large black space from 
the base to the middle, a blackish band beyond it and a ring near the 
apex, which is brown above : spines of tibiffi tipped with black; tarsi grey. 
This differs so materially from the specimens oiL.migratoria 
I have received from Germany, that I consider it to be a di- 
stinct species, and have therefore named it after Wm. Christy, 
Esq., who took it upon some French-beans in a garden on the 
Clapham-road in July 1826, and very handsomely added it to 
my cabinet. Independently of the wide difference in colour, the 
thorax is not of the same shape as L. migratoria^ the carina 
forms a depressed arch and is rather more pointed behind. 
Another specimen, captured last September at Ardmore in the 
county of Waterford by Miss M.Bali, has been obligingly trans- 
mitted to me for my inspection by Robert Ball, Esq. of Dublin: 
it is of the same sex as the one figured, but the elytra are much 
more spotted.

LiNN^us calls this division of" his genus Gryllus, Bulla (the 
name of a group of shells), at the same time referring to Geof- 
froy's work, where it had received the name of Acrydium. 

This variable genus is distinguished from the other Locus- 
t'ldiv by its very long scutellum and small elytra or superior 
wings, which, when at rest, lie close to the sides of the abdo- 
men. They live in fields, on hot and sandy banks, and among 
short grass and plants on the tops of walls even in cities.

Until other insects allied to Strepsiptera be found, its natural 
affinities must remain very doubtful, from the imperfect and 
peculiar structure of the mouth ; and there is not a single 
Order perhaps that might not be assumed to be related to it 
by analogy. As I have taken the greatest pains with the dis- 
sections, it is hoped they will require no comment in this 
place : after therefore observing that I consider the third joint 
of the antennae merely eccentric, — that it is doubtful whether 
the horny substances are mandibles or maxillae, since I be- 
lieve the palpi to be biarticulate ; and that it has been my 
good fortune to -prove that the appendages are anterior wings 
or elytra, — -I shall pass on to give Mr. Dale's valuable facts 
relating to our insects. 

" Every specimen of Andrena harbilabrh I have seen this 
year, from the 27th April to the 4th June, have contained 
larvae, pupae, or exuviae of Stylops, from one to three in each. 
On the 5th May I picked one out with a pin, on the seventh 
another rather immature, and caught one flying in the hot 
sun-shine over a quickset hedge in the garden ; it looked milk- 
white on the wing, with a jet black body, and totally unlike 
any thing else ; it flew with an undulating or vacillating motion 
amongst the young shoots, and I could not catch it till it settled 
on one, when it ran up and down, its wings in motion, and 
making a considerable buzz or hum nearly as loud as a Sesia : 
it twisted about its rather long tail, and turned it up like a 
Staphylinus. 1 put it under a glass and placed it in the sun ; 
it became quite furious in its confinement, and never ceased 
running about for two hours. The elytra or processes were 
kept in quick vibration, as well as the wings ; it buzzed against 
the sides of the glass, with its head touching it, and tumbled 
about on its back. 

" By putting two bees {A. lahialis) under a glass in the sun, 
two Stylops were produced ; the bees seemed uneasy and went 
up towards them, but evidently with caution, as if to fight, 
and moving their antenna? towards them retreated. I once 
thought the bee attempted to seize it; but the oddest thing 
was to see the Stylops get on the body of the bee and ride 
about, the latter using every effort to throw his rider. A large 
hole is left in the tail of tlie bee when the Stylops escapes, 
which closes up after a time. I have found five species of 
Andrenae infested." 

The specimen figured was bred from A?idrena labialis, and 
presented to me, together with others, for dissection, by my 
esteemed friend J. C. Dale, Esq., in honour of whom I have 
named the species. The minuteness of the second joint of 
the antennae, the small size of the second joint of the palpi, 
and the differently formed wings, are sufficient characters to 
distinguish it from any species hitherto described and figured.

The minuteness and value of these insects have prevented me 
from ascertaining one or two points with the accuracy I could 
desire : I hope, however, that some able entomologist may 
eventually possess ample materials for correcting any error I 
may have committed and for supplying any deficiencies that 
may be detected. 

The collar is extremely small, and the pseudelytra are much 
longer than in Xenos or Stylops; they are fixed very low 

down on the side and close to the anterior margin of the 
mesotliorax ; viewed above they look like pendants for the 
ears, whence the generic name. The thorax is shorter than 
in Slylops and more gibbose, as well as the postscutellum. The 
body is long and slender, but not having been able to get a 
clear view of the apex in Mr. Dale's specimen (D.) it may not 
be an exact resemblance of it. The long and slender antenna? 
are remarkable. The 4 anterior legs attached to the collar 
and mesothorax, are close together like those of Pulex, and the 
exceedingly long coxae enable the insect to porrect them very 
forward or to place the intermediate nearer the hinder pair 
as represented in the coloured figure : the tarsi appear to be 
formed of 2 joints only, which are much more slender in the 
first pair than in the othei's. It must be remembered that in 
Mr. Dale's specimen, the tarsi of the intermediate and the ter- 
minal joint in the posterior pair are wanting. 

I have not the least doubt that Mr. Walker's and Mr. Dale's 
insects are the same species, and the differences in the outline 
figures with regard to the form of the antennae and legs arise 
from Mr. Dale's having been drawn in a dry state, whilst that 
of Mr. Walker (W.) was relaxed in hot water. 

Mr. F. Walker first discovered a female ? at Southgate 
amongst grass, S-ith June. Mr. Dale next took a male? 
11th June 1830, by sweeping some flowers and wheat near 
Glanville's Wootton, and found it in his net when he returned 
home; and the end of June 1830 and July 1831 Mr. Haliday 
took 2 females in sweeping some herbage near Belfast. To 
all these gentlemen I am indebted for the use of their speci- 
mens, and to the last for his kindness in having presented me 
with one accompanied by the following interesting observations. 

" I have no clue to the family it may be parasitic on, for I have not 
found any bee with the larva in it; the most common in its locality 
are Andrena cineraria & albicans and Halictus 7-ubicundiis & albipes. It 
seems very delicate ; the only specimen 1 could succeed in bringing home 
alive I put under a watch glass, but having to leave it for an hour 1 found 
it dead, though placed in a cool spot. It moved with a vacillating but 
tolerably rapid gait with the upper wings extended and the lower rapidly 
vibrating, the abdomen, with which it smooths the wings, twisting freely in 
all directions. The antennas are kept apart with the branches divaricated, 
and the longer one generally bent in an angle at the articulation ; the 
palpi? mostly in motion. All the membranous parts are capable of much 
dilatation and contraction, and are fully expanded when in lively motion, 
but contract after death. The wings were cinereous with blacker nervures. 
Abdomen longer than the rest of the trunk, fleshy, of 8 segments besides 
the anal one bearing the appendage. The first three are softer, more ex- 
tensile and versatile than the rest, which have a single row of transverse 
spots down the back, one on each segment, of stronger consistence and 
darker colour, also a series of more minute ones down the belly. The colour 
of the membranous parts is cinereous yellow, the horny plates of a darker 
blackish-cinereous shade : the ovipositor tibiae and base of antennae nearly 
black, eyes deep black."— Mr. A. H. Haliday's MSS.

In the Cabinet of Mr. Dale. 

At the close of the last volume I had the opportunity of pub- 
lishing a second genus of the order Strepsiptera, and through 
the kindness of my friend Mr. Dale, I have now the pleasure 
of presenting entomologists with a most interesting insect, 
v*?hich has been named Halictophagus by its captor, from its 
feeding or living in the larva state in the bodies of the genus 

Mr. Dale says in his letter, " I took H. Curtisii the 15th of 
last August, in company with the males of Halictus aratus'^ 
which were in plenty, by brushing some long coarse grass and 

thistles close to the sea, on a rock called Durdle Door at Lul- 
worth Cove. In one of the Halicti I found a pupa so exactly 
at the apex of the abdomen, that I mistook it for an appen- 
dage, and killed the bee, otherwise I should liave bred the 
imago, as it was nearly matured. My Halictophagus seemed 
unable to run in the net, its feet being entangled in the same 
manner as those of Elenchus, which was the cause, I have 
little doubt, of the tarsi being broken in my specimen. 

" All the Strepsiptera appear to be short-lived, for the Ha- 
lictophagus died in the evening soon after I arrived at the inn. 

" I remember finding, a few years ago, a larva in Halictus 
4!-guttatus? which I took in the New Forest in April." 

It is unnecessary to point out the differences between Sty- 
lops {pi. 226.), Elenchus (pi. 385.), and Halictophagus: this 
splendid discovery of Mr. Dale's, which adds a fourth genus 
to the remarkable order Strepsiptera, if not the most curious, 
is, I think, by far the most interesting of the whole, from the 
antennae being rayed as in some of the Hymenoptera {Cera- 
phron Halidayi^ pi. 249. and the males of Eulophus, ^j/. 133, 1.), 
or rather lamellated like the club of the antennse in the Melo- 
lonthidae, and likewise from the greater number of the con- 
spicuous nervures in the wings ; notwithstanding these decided 
charactei's, we are still unable to find the slightest affinity be- 
tween this and the other orders. 

In describing Stylops in 1828, I stated that the third joint 
of the antenna? was merely elongated into a lobe, and that they 
were 6-jointed ; and I am now fully borne out in my opinion 
by the structure of those of Halictophagus. I find that Mr. 
Westwood has been pleased to observe, that I was not the 
first to discover that the pseudelytra were attached to the me- 
sothorax*. However that may be, I was the first, I believe, 
who proved it ; and if Mons. Latreille did entertain an opinion 
that the appendages were elytra, it is far from clear in xki^Hegne 
Animal, and in the 'Families Naturelles he states that the 
prebalancers are inserted on the sides of the prothorax. Mr. 
Kirby, misled by Mr. Bauer's drawing, imagined that they 
were attached to the coxae of the anterior legs, as represented 
in the Plate he refers to ; indeed they are so placed, that with- 
out dissecting the Stylops, it would be utterly impossible from 
a dead specimen to ascertain to what part they were attached. 

I take this opportunity of adding, that Mr. Templeton in 
examining the nest of Bombiis mnscorum^ found a specimen of a 
Stylops very similar to Elenchus Walker i, if it be not the same, 
the 7th or 8th of last August in the neighbourhood of Belfast, 
which induces him to think it may be a parasite of that bee. 

The Plant is Tragopogon porrij'oliiis (Purple Goat' s-beard). 

* Mr. Westwood says that I claim the discovery of the attacliment of the 
pseudelytra to the mesothorax ; in this he is not quite right ; I said, '• it has been 
my good fortune to prove that the appendages are anterior wings or elytra."

Dr. Leach has described in the Zoological Miscellany (above 
referred to) eleven species of this fine Genus, seven of which are 

ascertained to be inhabitants of Great Britain ; the unique speci- 
men figured, which is a female, was taken in the month of July 
at Windsor several years since by Mr. Griesbach, and presented 
to the British Museum by Dr. Leach. 

The larvae of this Genus greatly resemble those of the Lepidop- 
tera, except that they have twenty-two feet ; they have also two 
lateral apertures from which they are able to spirt a fluid, for what 
purpose we can only conjecture, probably it may be sufficiently 
fetid or noxious to protect them against the attacks of the destruc- 
tive Ichneumonida. When the larvae are full grown, they form 
for themselves an oblong hard case, which is generally attached 
to a twig or small branch of the tree they fed upon, within which 
they change to an incomplete pupa. 

The plant figured is Holcus mollis (Creeping Soft Grass) .

Li the Author s and other Cabinets. 

The Genus Trichiosoma was established by Dr. Leach in his 
valuable Monograph upon the Tenthredinida : it is closely allied 

to the Genus Cimhex ; from which, however, it is very distinct in 
the formation of the organs of mandueation, the labrnm being 
very broad, the mandibles are tridentate, and tlie relative propor- 
tions of the joints of the palpi are very different ; the most con- 
stant character in the antennae is the great length of the third 
joint, the tarsi have their joints angulated beneath towards the 
centre, not spined near the apex as in Cimhex, from which the 
males may be instantly known, by their wanting the membrana- 
ceous covering near the base of the abdomen, aud the four 
posterior thighs being furnished with a tooth. The dissections in 
the plate are taken from a male, in which sex the instrumcnla 
c'lhana far exceed those of the female in size, especiidly the lab- 
rum and mandibles. 

TiicMosoma laterale is a rare insect, specimens being only 
occasionally met with in the woods about London : IMr. Samouelle 
first captured a specimen at Coombe, in the month of April ; the 
one figured (which is a male) came from Darent ; and I believe 
Mr. Stephens has also specimens from the same neighbourhood : 
the other British species are T. sylvaticum Leach. ; Lncornm 
Linn. ; tibiale Steph. ; Scalesii Leach., and unidentatum Iicach. 

The larvae, like those of Cimhex, roll themselves up in a pecu- 
liar manner, and when full grown inclose themselves iu a hard 
case, which they attach to the plant they fed upon. One species 
{T. Liicoruiu) is very abundant upon the White-thorn (PI. 31.) ; 
and iu the winter, when the leaves have fallen off, the cocoons 
are easily collected ; and in April following the lly will make its 

Hyacinthus non-scriptiis Linn. ; 8cilla nutans Smith (Hare- 
bell Squill) is figured with the insect.

Except in the cabinets above recorded, I know of no British 
specimens of this valuable genus, of which Dr. Leach in the 
Zooloo-ical Miscellany mentions 2 species that were first de- 
scribed by Linnaeus ; and from our finding males only of the 
one and females of the other, it is exceedingly probable they 
are the same species, notwithstanding their dissimilarity, which 
would render the specific name of " dispar" more appropriate; 
the fact, however, of their being the same is not proved ; and 
if it should hereafter, I would strongly recommend that the 
name which Linnaeus gave to the male might be adopted, 
^^ AmerincE" being descriptive of the locality of the insect; for 
we are informed by authors that it inhabits sallows, living in 
society, and eating the edges of the leaves of those trees. 

Clavellaria Amerhice Linn, has been twice taken at Windsor 
in June : a figure of it will be found in Panzer's FawKS Ger- 
vianica, fasc. 65, pi. 1. mas. 

C. marginata Linn, is also figured by Panzer : the specimen 
represented in our plate was taken at Windsor also in June, 
by Mr. Griesbach. 

The absence of the membranaceous covering as well as the 
slight emargination at the base of the abdomen, and the an- 
tennae being composed of fewer joints and a longer club, are 
characters to distinguish Clavellaria from Cimbex and the 
neighbouring genera, no less than the organs of manducation; 
and the extraordinary length of the jaws in the males is not 
less characteristic. If then there be good characters to es- 
tablish so many genera, (and that there are, no one can doubt, 
when it is recollected that Dr. Leach in the division of Cimbex 
employed only external distinctions,) the group with clavate 
antennae, viz. the Citnbices, will form an excellent family; and 
the oeconomy of the Tenthredinidce, as well as their peculiar 
structure, may render it advisable in a more advanced stage 
of science to separate them from the Hymenoptera and form 
them into a new order, an idea which has long been enter- 
tained by various authors. 

Pyrola media (Intermediate Winter-Green), from the heaths 
in the north of Perthshire, appears to be the plant figured.

Although the more rounded labrum and acute mandibles, 
as well as the form of the 4th joint of the maxillary palpi and 
the great breadth of the 3rd joint of the labial palpi, are im- 
portant differences to distinguish our genus from Abia ; a 
more obvious character is to be found in the antennae, each of 
which is composed of 6 joints only, the club being formed by 
2 instead of 3 articulations. 

At present there is no other species of this genus described: 
the one figured is rare in this country, and I have had no op- 
portunity of examining a male. The females have been taken 
by J. F. Stephens, Esq. in Coombe Wood in May; from which 
we may infer that the males are more scarce (an opinion that 
is corroborated by the females being constantly figured, and 
the specimens I have received from Germany for dissection 
being all of that sex), a circumstance that is somewhat sin- 
gular, because in Abia, to which it is so closely alhed, the 
males are by far the more common sex.

Abu was separated from the Cimbices by Dr. Leach, and is 
easily distinguished from his genus Zarcea, which it most re- 
sembles, by the three last joints of the antennae forming a club, 
whereas in Zarcea it is composed of only 2 ; and the singular 
quadrate spot upon the abdomens of the males at once distin- 
guishes that sex from the whole family. 

Abia nigr-icornis appears to have been considered by Lin- 
naeus as the female of Tenthredo nitcns, and by Fabricius as a 
variety of Civibex sericea. Amongst other distinctions, how- 
ever, the colour of the antennae, the brown markings of the 
wings, and the situation and form of the spot upon the ab- 
domen of the males are sufficient, now that the sexes of both 
have been taken, to justify its being recorded as a distinct spe- 
cies. It was, I believe, never before figured. It has been taken 
at Coombe Wood, by J. F. Stephens, Esq., in the month of 
June. A sericea, the other species inhabiting this kingdom, 
has been found on heaths upon Furze-bushes, in June, and 
sometimes occurs in considerable abundance : it is figured by 
Donovan in his Brit. his. v. 12. pi. 402.

We have only three British species of tliis pretty genus of La- 
treille's, which rival even the Lepidoptera in the beauty of their 
antennse ; and nature;, guided by the same principle, has bestowed 
this ornament alike in both Orders upon the males, which still 
further involves in mystery their use and quality; since, if form 
were material, the power of one sex would either be very different 
or very superior to that of the other ; — if the sense of feeling in- 
deed be the only faculty they possess, their form is not of so much 
importance ; and like Lehmann we shall be inclined to adopt this 
opinion, if we consider their general situation, their porrected 
attitude when in action, and still more the uses to which they are 

Lophyrus Pini is a rare insect in Britain : the female has been 
taken in Derbyshire, but the pine forests of Scotland are the most 
productive places for them : L. pallidtcs of Leach was found in 
the larva state by that gentleman at Oban in Scotland, upon Pinus 
sylvedris. (PI. 7.) On the 6th of September they spun cocoons; 
on the l-ith of June following one female hatched, L. riifus 
King, is not uncommon in the same country, and is also occasion- 
ally met with at Birchwood, June appears to be the month in 
which all the species are found in the imago state, and the males 
are by far the rarest ; that of L. pallidus is unknown, and I have 
seen but one British male of L. Pini. 

De Geer devotes the whole of tab. 36. vol 2. to the illustration 
of L. Pini; and his history of it at p. 971 is not less interesting. 
The larvse (says that author) are gregarious, of an obscure ochre 
colour with a row of large black spots down the side, when full- 
grown with another row down the back : they assemble in July 
upon the branches of the pine in large troops of more than a hun- 
dred ; they commonly repose along the leaves, having their heads 
inclined on one side ; they are very voracious, not only devouring 
the straight leaves of the pine, beginning at the end as one eats a 
radish, but also the bark of the young shoots ; and after having 
despoiled one branch of its leaves, they go in a body and fix upon 
another, until so many branches are stripped that their habitation 
becomes conspicuous. When touched they raise their heads and 
let flow from their mouths a drop of clear resin, which has the 
scent and consistence of that exuding from a wounded branch of 
the pine. In every state the sexes may be known by their size ; 
even the cocoons which are fixed to the branches of the pine are 
much smaller in the males than the females ; the larvae form 
cocoons about September, but they do not change to pupae until 
the spring ; and one of Dr. LeacVs caterpillars of L. jiallidus 
remained two years in that state without nourishment, which could 
not happen if they were not perfectly secluded from the air : the 
males bred by De Geer appeared in May, — the females did not 
hatch till June.

Fabricius having established the genus Hylotoma, in which he 
united several very excellent genera, Latreille afterwards separated 
them, and retained under that name the insects which compose 
Jurine's genus Cryptus : Dr. Leach has again divided the group. 

extracting the species with furcate antennse, for which he has 
retained Jurine's name Cryptus, leaving the remainder of the 
group under Hylotoma, following Latreille ; and it is only to be 
regretted that he did not give another name to the genus, and 
thereby avoid the confusion which Jurine has introduced by 
employing the name Cryptus here, when Pabricius had 3 years 
before given that name to a genus of Ichneumonidce, wliich Jurine 
was aware of, from his referring one of his divisions in that 
family to Eabricius^s genus in a subsequent page ; and had not 
Panzer published those IcJmeumonida under the name of Alomya, 
by wliich they are now well known, it would still be necessary to 
substitute a new name, in which we should only be doing justice 
to Fabricius. 

The male of Cryptus pallipes (a figure of which has never 
before appeared in any work) was first taken at Coombe Wood, 
by Mr. J. King ; and was named and described by Dr. Leach, 
and deposited in the British Museum. J. F. Stephens, Esq. 
was afterwards so fortunate as to meet with both sexes of tliis 
extremely rare species in June, at the same place : the other 
species {Tenthredo furcata Vill., C. ViUersii Leach) has been 
taken at Bristol in June ; it is figured by Panzer in his Fauna 
Insectomm Germanica, fasc. 46. tab. 1. ; and by Coquebert in 
his Ulustratlo Iconographica Insectorum, tab. 3. fig. 4. mas. I 
have retained Villers's name, although it is objectionable, from its 
being a generic rather than a specific one, and descriptive of the 
male only ; because as the greater proportion of insects have been 
named from one sex, we shall never have our nomenclature 
settled, if it is to be disturbed upon such occasions.

The division of Fabricius's genus Hylotoma has been already 
explained in the account of Cryptus (fol. 58) : it is therefore 
only necessary here to observe, that, independent of the diffe- 
rence of the instrumenta cibaria, there are external characters 
that fully justified Dr. Leach's separating that genus from 
Hylotoma; the simple antennae in both sexes in Hylotoma, the 
branch from the marginal cell of the vikings, and the spines of 
the 4 posterior tibiae, are the most remarkable. The genus as 
it now stands contains 14< British species, which I shall here 
enumerate, observing that the first may possibly belong to Le 
Peletier de Saint- Fargeau's genus Ptilia.

allied to H. pagana, from which it differs in having more trans- 
parent wings, brown and pubescent tibiae, and black tarsi : it 
appears to be a local species, as I have never met with it my- 
self, excepting at Darent, where it is taken in June, in which 
month all the species above recorded are to be found.

In the Author's and other Cabinets. 

Athalia nearly resembles Hylotoma and Selandria, but is 
distinguished from both by its antennae, which are more cla- 
vate than the latter and have more joints than the former. 
Di-. Leach described them as 10-jointed, but in the species 
figured the males have only 9 joints (fig. 1.), and in the females 
an nth joint is indicated. Six species are recorded in the 
Guide as British, and the one before us is well deserving our 
attention from the injurious habits of its larva. 

The T. spinarum is stated by Fabricius to be destructive to 
turneps, and the T. centifolicc of Panzer is undoubtedly the 
same species. 

In walking through the turnep-fields last year the most 
casual observer must have noticed the mere skeletons which 
the leaves often exhibited, the fibres only remaining, the mem- 
brane being consumed by larvae called Blacks by the farmers. 
From the middle of August to the 20th of October, at which 
lime they were full-grown, I observed them feeding on the 
leaves of the turneps; they often varied considerably in stature, 
and the bulb was evidently reduced in size through their 
agency. The larvae or caterpillars when full-grown are some- 
times green, but generally of a lead or slate colour, being black 
before changing their skins, and always appearing darker when 
rolled up : they form an oval horny cocoon either amongst the 
leaves on the ground or under the clods of earth, where they 
become pupae. The fly appears principally in August and 
September, but I have found them as early as the 29th of 
March, and as late as the middle of October. I first observed 
these flies in abundance in a potato-field at Battersea, and 
afterwards in a field near Heron Court ; but last year they 
were distributed over the whole country, after an absence in 
many places, I was informed, of upwards of 30 years ; they 
have appeared again this year, and Mr. R. Taylor and my- 
self, in a botanical excursion last August, saw the flies coming 
out of the ground in myriads in a ploughed field near Bristol, 
where potatos had apparently been grown. 

The Jlies do not appear to be attached to any particular 
plant ; whether the larva; will attack any other than the En- 
glish turnep I cannot determine, but it is a remarkable fact 
that they will not touch the Swedes. I believe it is not diffi- 
cult to destroy them, for if they are brushed off the leaves it 
seems they are unable to crawl upon the ground and recover 
their station ; they consequently perish unless they are fiill- 
grown at the time : but as there is a constant succession from 
August till near November, the operation of drawing a hurdle 
or something over the turneps ought to be repeated at inter- 
vals during that period. Wet, also, is said to destroy the 
blacks, and ducks turned into the fields clear them off' rapidly 
and grow fat upon them. 

The full-grown larva is represented feeding upon the tur- 
nep, Brassica llapa.

If we take the typical species of Allantus and compare them 
with those of Tenthredo, pi. 692, the differences are very 


evident, especially in the anteniiEe; but if we proceed in the 
comparison we shall find that they gradually approach, so 
that at last there is little to distinguisii the genera excepting 
the length of the 3rd joint of the antennae. I cannot speak 
with certainty regarding thetrophi, not having examined them 
sufficiently, but 1 must not omit to notice a remarkable de- 
parture from the typical structure, which Mr. Haliday has 
pointed out to me in a species allied to Selandria, with very 
short pal[M, containing only 5 and 3 joints instead of 6 and 4. 
Mr. Haliday has only seen the males which he took at Holy- 
wood, and has named them seminigra, and perhaps Brachy- 
thops may be considered an appropriate generic name. 

In addition to the 42 species of Allantus recorded in the 
Guide, I am now able to add three more. The following 
sections may probably be found preferable to Dr. King's, 
which are based on the colour of the antennje.

This species was first observed by Mr. Shuckard in Battersea 

fields, where it appeared in abundance the end of June. Wish- 
ing to see the insect alive, I went to the spot the beginning 
of July, when 1 found 2 females upon the flowers of Sinajns 
nigra and also 6 larvce, one of which I have figured : they 
were feeding on that plant, and I believe upon S. alba, pi. 
546 ; they ate the leaves, stalks and flowers ; one soon changed 
its skin, when it lost all the black spots except those on the 
head, and it buried itself on the 17th, and the others success- 
ively, but unfortunately I could not rear them : there is little 
doubt however that they were the larvee of A.Jlavipes. 

Dr. Klug having described 2 species of Allantus under the 
name of di spar, I have lound it necessary to revert to Four- 
croy's name, although it is not perhaps so appropriate.

remainder decreasing in length, the apical joint short and ellip- 
tical in the male. 

Labrum inserted under the clypeus, orbicular, slightly truncated 
at the base, the margin ciliated with longish hairs (2). 
Mandibles very similar, elongate, linear, convex and hairy ex- 
ternally, the apex forming a large claw, with a small tooth be- 
low and a tubercle at the middle (3). 

Maxillce slender, terminated by an ovate lobe, with an internal 
one equally large, and very pubescent, the apex acuminated. 
Palpi long pubescent and 6-jointed, basal joint short, 2nd and 
3rd the stoutest, the former scarcely so long as the 3rd or 4th; 
5th and 6th a little shorter, the last slightly clavate (4). 
Mentum corset-shaped. Palpi attached to the anterior angles, 
rather long, hairy and 4-jointed, basal joint obovate, 2nd twice 
as long, curved and ciliated before, 3rd and 4th much broader, 
especially the former which is ovate, the latter ovate-conic. Lip 
rather large and cordate, composed of 3 lobes, the outer ones 
ovate-trigonate, the central one narrow, dilated at the apex (5). 
Males generally smaller than the females. Head transverse, base con-

The differences between Tenthredo and Allantiis are very 
slight; the 3rd joint of the antennae is evidently longer than 
the 4th in the latter genus, which seems to be the essential 
character. Tenthredo comprises 23 British species, of which 
I shall notice a few in my own cabinet. 
2. cingulata Fab.— Curt. Brit. Ent. pi. 692. 

The remarkable insect figured is a hermaphrodite, the right- 
hand half being feminine, that on the left masculine, so that 
in the specimen the antennae, abdomen, legs, and wings are 
not symmetrical : the sexual organs are representeil at fig. 6. 
Since the attention of naturalists has been called to this sub- 
ject, a large number of insects of this description have been 
discovered, especially amongst the Papilionidae. I have on 
a former occasion alluded to an example oi Smerinthus Pop7ili 
in my possession, but the most extraordinary specimen that 
has come under my observation was a North American 
Lucanus, which Mr. Raddon showed me. Never having seen 
any other Hymenopterous insect of this kind, I have been in- 
duced to figure the Tenthredo in the annexed plate; and as 
the sexes vary in the colour and markings of the abdomen, &c., 
they are rendered conspicuous in the figure. I took this indi- 
vidual with a vast number of i'emales off Fern in the New 
Forest in June; the males were very rare. I have also found

Klug considers T. dimidiata., scutellaris, nassata and Tilice of 
Panzer to be one species, which he has named instabilis; but 
as the neuration of the wings is so different in T. dimidiata, I 
think that at least must be distinct. 

Mr. Dale possesses a specimen with seven legs.

Emphytus is placed between Dolerus and Croesus {pi. 17.); 
from the former it is at once distinguished by the great length 
of the first submarginal cell, and from the latter and the Ne- 
mati also, by its having 2 marginal and only 3, instead of 4 
submarginal cells.

The insects of this family may be easily known by their perfectly 
sessile abdomens, by their peculiar oviduct formed of 2 serrated 
lamella, and by their ample wings of many cells. Many of them 
fejo-n death when alarmed and bend down their heads and antennae 
solbrcibly as to show the membrane that connects the thorax. 

The larvae of this family bear a strong resemblance to those of 
the Lepidoptera, but they have more abdominal or false feet, they 
feed upon the leaves of plants, are very sensitive, and have a peculiar 
manner of rolling themseves up, when touched, like a convoluted 


The present genus was separated from Nematus by Dr. Leach in 
the 3rd vol. of the Zool. Misc. in a paper upon the external cha- 
racters of the Tenthredinidae : the hinder legs, dilated in both sexes, 
indicate a different mode of life from the other Nemati and are pro- 
bably useful in flight. 

When the first edition of this work was published, only one spe- 
cies of Croesus was known, but in the 1st vol. of the " Annales de 
la Soc. Ent. de France" M. Foulgues de Villaret has described 3 
new species, 2 of which are supposed by Mr. Stephens to be British. 

1. septentrionalis. Linn. Curt. Brit. Ent. pi. 17. ?. 

This was formerly considered a rare insect, being taken occa- 
sionally at Darent-wood Kent, in Norfolk, near Lyndhurst, &c. in 
June, but it now sometimes appears in abundance. Mr. C. Parsons 
observed the larvae near Southend feeding on the hazel ; they agreed 
with the figure in our plate copied from the Ent. Mag., but did not 
change to flies till July. Mr. C. J. Paget found the larvae on willows 
in a meadow near Great Yarmouth the end of August ; they were 
small but "in such numbers," he says in his letter, "that some trees 
are perfectly bare: I never observed a more extensive blight : there 
are literally thousands in this meadow alone." I took a female at 
Bungay in Suffolk several years since. 

2. varus? Be Vill. Ann. Soc. Ent. Fr. 1. 306. ;;/. 11./. 8. 3. 

Palpi and clypeus white : abdomen black, middle of the 2nd segment and the 
following to the 7th ferruginous: 4 anterior legs pale ferruginous, hinder 
thighs ferruginous tipped with black : wings unclouded : expanse 9 lines. 
Beginning of June, Birch-wood. Ste. 

3. laticrus De Fill. v. I. j}. 307. pl.n.f.7. ? . 

Palpi reddish, 3rd, 4th, 5th and 6th segments of abdomen ferruginous: legs 
black, tips of anterior thighs ferruginous, anterior tibiae and tarsi reddish 
white, intermediate pitchy, base of the former whitish : superior wings with a 
fuscous cloud : expanse one inch. 
Said to have been taken near London. 

I think it very probable that Mr. Stephens's specimens are merely 
varieties of the male and female of C. septe7itrionalis. 

The Plant is Crepis tectonm, Smooth Hawk's-beard.

In the Author's Cabinet. 

Although most of the males of Cladiiis may easily be re- 
cognised, the females are not readily distinguished from some 
of the Nemati, N.pallipes St. Farg. for example, in which the 
3rd submarginal cell receives a recurrent discoidal nervure 
in the centre ; this submarginal cell, however, is the longest in 
Nematus, and the 1st discoidal cell forms a less perfect triangle 
than in Cladius; and although the 1st submarginal cell is in- 
distinct in Cladius, it is altogether wanting in N. pallipes, 
notwithstanding many of the Nemati have 4 submarginal cells. 
Cladius was established by Latreille, in his " Considerations 
Generales ", in 1810, and contains the following British spe- 
cies : 

1. C. difformis Panz. 62. 10 mas. 

Found from the end of May to the middle of August in 
Copenhagen Fields, Coombe-wood, on Blackheath, in Darent 
Lane ; near Bristol ; Glanville's Wootton and Stafford Dorset, 
J. C. Dale, Esq. ; Tynemouth Northumberland, G. Wailes, 

Two or three years since my friend Mr. C. J. Thompson 
gave me some larvae * that he found at Fulham on the under 
side of the leaves of the China rose, eating small holes through 
them : they were thickly clothed with short upright hairs, the 
head was ochreous, with two minute black eyes : the body 
green with a deeper line down each side and a darker one 
along the back ; the anal feet did not assist them in walking. 
They were full fed about the 28th of July, when they spun 
cocoons amongst the leaves, and hatched the 1 1th and 12th of 
August : one that was stung by an Ichneumon produced a 
Tryphon the 20th of August.

5. C. pilicornis Curt. Brit. 457 cJ. 

This insect, which I at first thought had only been the female 
of C. diffbrmis, I found near London in June ; the specimens 
which I consider to be the females of this species have simple 
antennas, but longer than in C. difformis.

Li the Cabinets of the British Museum and the Jlulhor, 

Dr. Leach's group Xiphydriadae has been always included 
by Latreille with his Tenthredinidae : it is not necessary here 
to inquire whether it be expedient to establish two families, 
but it is evident that Cephus does not belong to Dr. Leach's 
group ; for the perfectly developed and trilobed labium and 
long palpi show that its habits are similar to those of the 
Tenthredinidae ; its posterior tibiae also, spurred towards the 
middle, are similar to those of Hylotoma {pi. Q5) : and it is 
stated by the learned naturalist of Paris, that the larvae of a 
new species (C ahdominalis^ Lat.) live upon the flowering buds 
of fruit-trees, and do them a great deal of mischief.

Xyela, which so perfectly connects the Tenth redinidae with 
the Siricidae or Uroceridse, evidently belongs to the family 
Xiphydriidae of Leach, although Dalman, in his valuable 
paper upon this genus in the Stockholm Transactions, and 
subsequently in the " Analecta Entomologica," considers that 
it belongs to the Uroceridse : but the ample wings and large 
stigma bear considerable affinity to the genus Lyda, pi. 38], 
whilst it cannot be denied that the exserted and compressed 
oviduct brings it close to Xiphydria. Dalman has overlooked 
the twelfth joint of the antennas, which is the smallest, and 
also one of the joints of the labial palpi ; the former he describes 
as eleven-jointed, and the latter as triarticulate. Although 
the conformation of Xyela is altogether remarkable, no part 
is, I think, more curious than the maxillary palpi, which look 
like a little pair of feet attached to the insect; and from the 
legs being placed far behind, it is not im.probable that the 
palpi may occasionally be employed like those members to 
support itself; the 2nd and 3rd joints are hollow, which may 
enable the insect to fold them close for protection, and the 
terminal joint is perfectly flexible. 

Of this rare and interesting insect I took three females in 
1811, upon umbelliferous plants in the vicinity of fir-trees in 
Norfolk, where those trees are abundant ; it has been taken 
at Southgate, by Mr. F. Walker, amongst grass, the middle 
of May, and by Mr. Newman, off the spruce-fir in Birch- 
wood, the middle of April. The male I had never seen when 
the first edition of this folio was published ; but Mr. Dale has 
since enriched my cabinet with both sexes, which he found at 
Stafford, and also on a birch-tree on Knighton heath the 3rd 
of May. It appears to be not uncommon in Sweden, on young 
Scotch firs, during the month of July; but there is another 
species named X longula^ discovered by Gyllenhal, and de- 
scribed by Dalman, which is much rarer; it is two or three 
times as large as X piisilla, with a piceous ovipositor. 

ChcErophyllum sylvestre. Wild Chervil, being the umbelli- 
ferous plant upon which I believe my specimens were found ;

This curious insect bears a considerable resemblance to the 
TenthredinidaB, but is nearest allied to Sirex, as is evident by 
the triarticulate labial palpi : it may therefore be viewed as the 
connecting link of Xiphydria and Sirex. The mouth affords 
some further peculiarities ; and I regret that I did not discover 
the external part of the labrum, having found only a mem- 
branous lobe inserted beneath the clypeus : neither could I 
procure a male for examination. The mandibles are rounded 
and spoon-shaped, the external lobe of the maxillae is rigid, 
and the 2nd joint of their palpi the smallest, and the labium 
is not divided, but hollow and similar to the Ichneumonidae. 

Oryssus is very peculiar in its structure : the sexes vary con- 
siderably; the antennae, which are inserted under the clypeus, 
are 11-jointed in the male, and 10-jointed in the female; the 
oviduct is capillary and rolled up spirally in the abdomen, as 
it is, I think, in some of the Cynipidae and Diplolepidae ; the 
submarginal cells are only 2, but 3 are indicated ; the anterior 
tibiae are so singularly formed towards the apex in the females 
as to appear like a basal joint to the tarsi, which are only tri- 
articulate in the fore feet of this sex. 

The only species of the genus is 

O. coronatus Fab. — Curt. Brit. Ent. pi. 460. ? . — Coq. tab. 5. 


Black shagreened : eyes fuscous, a white stripe on each side 
the face ; antennas with the 3rd joint except at the base, the 
4th, 5th, and a spot at the base of the 6th white ; abdomen 
smooth and rufous, excepting the 2 basal joints : wings, supe- 
rior with the apical portion fuscous, excepting the tip which is 
transparent as well as a band beyond the stigma, this as well 
as the nervures is piceous; a spot at the apex of the thighs 
and an abbreviated stripe outside the tibiae white ; tarsi and 
inside of the posterior tibiae subferruginous. 

Two specimens of this rare insect, taken by Dr. Leach, are 
in the British Museum : the male is smaller than the female : 
the former was captured in Devon, the latter in Darent Wood, 
in July. It is said to inhabit sandy situations : and the disco- 
very of these insects in England is very remarkable ; for I be- 
lieve they have never been found to the North of Brives in the 
South of France. 

Latreille says these insects are lively and restless : they re- 
pose in preference upon old trees, exposed to the sun. They 
run over a portion of their height with rapidity in a straight 
line, taking, when they are alarmed, a lateral or retrograde 
direction. Scopoli found them upon fir-trees, and Latreille 
upon old hornbeams in the spring. 

The Plant is Phalaris canariensis (Manured Canary-grass).

The Sirices appear to be most destructive insects to dead 
trees and timber ; which is not surprising when it is stated, 
that tlie eggs are deposited in clusters of two or three hun- 
dred ; and the largest maggots, when full grown, are about 
1^ inch in length. It is remarkable how much insects whose 
. arvae are xylophagous vary in size ; for, whilst some speci- 
mens o^ Sirex juvencus are as large as those represented in the 
plate, others (especially females), from the same trees are not 
more than a quarter the size. There are two species of this 
fine genus found in Britain, the sexes of which are so dissi- 
milar, that they have been described under four names.

For a fine series of this insect, including the beautiful spe- 
cimens figured, I am indebted to my kind friend the Hon. 
Charles Harris, as well as for the following valuable observa- 
tions relating to the destruction of fir-trees in the plantations 
near Heron Court, the seat of the Earl of Malmesbury. 
" With us," says Mr. Harris, " at the age of twenty the fir- 
trees sometimes die to a great extent. The summer of 1825 
or 1826 was peculiarly destructive to them, from its intense 
heat and drought; and I am certain that I never saw any 
trace of a Sirex except on dead trees. The smell of the tur- 
pentine would fully account for this ; and if you remember, the 
only spot where we could detect the Sirex in the standing 
plantation of shorter trees, was on some dead stumps that had 
evidently been overgrown by the others. The day after your 
departure I went to visit the fir wood, when I had the good 
fortune to extract eight males of the Sirex ; two of these I 
purposely let go ; they proved very strong on the wing, and 
ascended with a loudish hum to an invisible height." From 
this it appears that the mischief arises from allowing dead 
trees to remain standing or lying about ; and timber ought to 
be well examined before it is employed in building ; for I un- 
derstand that considerable numbers of the males have been 
taken flying about the tower of York Minster, no doubt seek- 
ing the females which were issuing from the timbers that sup- 
ported the roof, and which would be, of course, greatly 
weakened by the constant and continued operations of the 
Larvae, as well as rendered more combustible by the multi- 
tude of passages and the quantity of dust which they create. 

The plant is Lapsana communis (Common Nipplewort).

The remarkable insect which is the type of our genus, has 
been ascertained by the late Dr. Arnold to be one of those 
destined to destroy the Blattse ; whether by depositing its eggs 
in their larva or ova, is I believe not known.

These remarkable insects are by no means common : I had 
not seen one alive for many years until last June, when I took 

several specimens of the F. Assectaior, and they reminded me 
in their flight of the Ammophila vulgaris, from the singular 
manner in which they raised their bodies. The following 
observations I have copied from Latreille. " They live upon 
flowers, and often elevate their abdomens in a state of repose : 
during the night, or when bad weather prevents them from 
flying, they fix themselves by their mandibles to the stalks of 
different plants, and are then almost in a perpendicular posi- 
tion. They are often met with in dry and sandy districts, 
flying with solitary bees and Spheges in order to discover their 
nests and take possession of them, or to deposit their eggs by 
the side of those of the above insects, or upon their larvae, which 
become their prey. The larvee undergo their metamorphoses 
in the same nest where they lived." Linnaeus says, on the 
authority of Bergman, that /. Jaadator inhabits the larvae of 
Apis tnmcoru7n,Jiorisom7iis, and Sphex Figulus, examining with 
its antennae where the larva is concealed, it flies away, returns, 
and deposits an egg in it.

In 1828 I published a fioiire, &c. o{ Ichneumon Atropos (PL 
231), which appeared to be a typical species, but Gravenhorst 

in his Ichn. Europ. having called the group Trogus, to 
which that species belongs, it will be necessary to adopt his 
name, and I avail myself of this opportunity to illustrate the 
group which he now considers as the true Ichneumons. Having 
given in my Guide the most complete catalogue of the Ich- 
neumonidae that has ever been published, a reference to that 
will show the species belonging to this family, and I cannot 
perhaps do more service to those who do not possess Graven- 
hprst's work, than translate his characters of the genera and 
sections of the tribe before us.

In the Cabinet of Mr. Haliday. 

This genus, Mr. Haliday says, seems more allied to Hemiteles 
than to any of the other Ichneumonidse, indeed sometimes 
they can only be distinguished by the areolet, or a little dif- 
ference in the length of the aculeus. The males of Stilpnus 

and of some species of Atractodes are also very similar. I 
have not heard of any of the species being bred from the 
pupa ; and when my Guide was published, one only was 
known to inhabit these Islands, but since that period the fol- 
lowing have been detected in England and Ireland ; and I am 
indebted to A. H. Haliday, Esq. for specimens, as well as the 
loan of the example figured.

Mesoleptus is a group detached from Tryplion by Graven- 
horst : it contains 70 or 80 species, and about 50 have been 
detected in this country. It is distinguished from Tryphon by 
its long and slender petiole, and the areolet is generally of a 

different form ; the labium is longer and not deeply notched, 
and the joints of the labial palpi appear to be differently pro- 
portioned. It must however be remembered that there are 
numerous modifications in this genus; in some species the 
antennas are much shorter than the body, in others longer 
and capillary : the petiole varies much in the length, and is 
often considerably dilated at the apex ; the abdomen is more 
or less clavate, the ovipositor rarely visible from above; the 
areolet is frequently trigonate and sometimes wanting, and the 
hinder legs are rarely thickened.

more natural ones might be obtained from the proportions of 
the petiole, if not from the areolet and the metathorax.

Mr.Haliday has discovered two new species, one T. mirifluus 
(the type of his proposed subgenus Cleniscus) occurs on Wil- 
lows from July to Sept. ; the other he has named T. Curtisii, 
and says, " The only specimen I have seen belongs to the same 
type, as well as T. sexlituratus and about three species besides 
in my cabinet." 

For the following observations I am indebted to the same 
gentleman, and am sorry I can only give an abridgement of 
them. " T. varitarsus I have sent a specimen of, to illustrate 
Gravenhorst's note on this species : he errs in supposing it 
the effect of accident ; 3 out of 4 specimens occur thus affected. 
I subjoin extracts from my notes on the subject, with a sketch 
of the larvag (for such they are, and not eggs) in different 
stages. The Tryphons occur in August and Sept. on Wil- 
lows and Ragwort, and I have found as many as 18 larvae 
attached to one insect : at first they are all of a smooth pear- 
shaped and shining opaque waxy tint (fig. B) ; in a kw days 
they appear as represented at C, which is the underside : at 
this stage its voracious powers develop themselves, and I find 
the oldest generally making a meal of his next neighbour, who 
is soon sucked to the skin. I observed two motions in the 
mouth, one an opening and shutting of the mandibles, the 
other a general dilatation and contraction of the membrane of 
the mouth. Beyond this they show little signs of life while 
attached to the oviduct, but on being removed, which is easily 
done without injuring them, the darker ones have a slight 
jerking motion." 

Neither Mr. Hal id ay nor myself know the male of T. vari- 
tars7is, but all the females I have seen have had these nits 
attached to them ; each appears to me to be an animal con- 
tained in a bladder which has a peduncle at the lower end (B), 
by which it is attached to the base of the oviduct (A) ; they 
are there nourished, but whether the animal ever leaves the sac 
I am not able to determine : I think it probable, since I found 
that the bladders attached to the upperside of the abdomen of 
a female Dyticus inarginalis contained an Hydrachna or Lim- 
nochares, the drawings of which I have by me. 
The Plant is Spergula nodosa (Knotted Spurrey).

Although Jurine fell into error by servilely following his fa- 
vourite system, and by that means has collected together, as in 
the present instance, a mass of insects differing exceedingly in 

structure, still by selecting his type to draw our characters 
from, without reference to any of the others, we shall be able 
to make a sound genus of Anomalon. 

Jurine's genus is distinguished from most of the Ichneu- 
monidae by the absence of the areolet, or second submarginal 
little cell, so common to this family, and from many others by 
the large cell joining the first submarginal one, which is im- 
perfectly closed next the posterior margin in A. Vesparum,; but 
it is not so in Jurine's type, A. Icetatorius. There are a con- 
siderable number of species that agree with these insects in

2. Vesparum Nod, 

For specimens of this Anomalon (probably females), one of 
which is figured, we are indebted to the zeal and liberality of 
Mr. R. Wood of Manchester, who transmitted them with the 
nidus and following observations upon this singular insect. 
" In examining the combs of some Wasps' nests, (near the 
end of July probably,) in one of them I discovered many cells 
about half the length of those of the Wasps, and capped with 
wax. I put the comb into a glass jar, and the day following 
had the gratification of finding that three had eaten their way 
out of the cells. I think they were the liveliest insects I ever 
saw ; yet on going to look at them again, I found that several 
Wasps had emerged from their cells and had actually eaten 
two of them. I then took out the comb, and destroyed the 
young Wasps by running a pin through them in their cells, 
and again put the comb into the jar ; and in a few days three 
others came out. I fed them with honey, and they seemed 
to be very fond of it." Nothing has transpired since the comb 
has been in our possession ; but we expect that those cells 
containing the Anomalon, will produce the other sex of the 
insect in the course of next summer. The cells occupied were 
in various situations, from two to four together : each cocoon 
was hexagonal, and filled the inside of the Wasp's cell; it was 
very tough and silky, round at the bottom and flat at the top. 
It is worthy of remark, that the cells of the Wasps containing 
the Anomalon were closed like the others ; and upon opening 
them the exuvia of the Wasp's grub filled n space about one- 
third of the cell, from which we conclude that the eggs were 
deposited in the bodies of the larvse and lived in them till they 
became nymphae. 

The plant is Inula pulicaria (Less Fleabane).

Li the Cabinets of Mrj Davis and Mr. S. Sulivan. 

Fallen states that the true Ichneumons deposit their eggs in 
larvae that feed on the leaves of trees, and in pupae which lie 

near the surface of the earth ; it appears to me that they prefer 
naked caterpillars, and probably puncture them after they 
have descended into the earth, but before they have changed 
into chrysalides. 

The following list of British species belonging to this nu- 
merous genus, incomplete as it is, will enable any one to re- 
cognize those insects which belong to this particular group; 
and manuscript names without descriptions would only be an 
incumbrance, since Professor Gravenhorst is about to publish 
a Monograph upon the family.

J« the Cabinet of the Author. 

The vast number of species contained in Ichncumonida:^ to- 
gether with the difficulty of seizing distinctive cliaracters, has 
either caused this family to be totally neglected or but imper- 
fectly understood in most countries, but in none more so than 
in our own, where the Coleoptera and Lepidoptera, with the 
exception of the Tenthredoes and Bees, have entirely engaged 
the attention of the entomologist till within the last few years ; 
by which means not less than 600 species have been confused 
under the title of Ichneumon, instead of taking advantage of 
the improvements suggested by our neighbours, which, how- 
ever imperfect, must form the basis for a more complete di- 
vision and natural arrangement of this family. 

Had Fabricius, who first divided the Ichieumonidce into 
genera, done it with that care and attention which so difficult 
a task required, there is no doubt but Latreille would have 
gone further than he has done into the investigation of them ; 
but the Fabrician system is so perfectly artificial, that the 
author of it himself could not follow it without making " con- 
fusion worse confounded," as is evident from a slight view of 
the genera in his last work. 

Difficult as the task is, and unequal as we must acknowledge 
ourselves to perform it, we can only promise to lend our aid by 
separating groups as opportunities may offer, thereby lessen- 
ing the mass that at present is nearly unmanageable, which 
will we hope enable those, who have better opportunities and 
more leisure than ourselves for studying this family, to accom- 
plish an undertaking so absolutely necessary to a knowledge 
of the Hymenoptera. 

Alomya was first established by Panzer, and has been 
adopted by Fallen: yet we are so imperfectly acquainted 
with the sexes, that Jurine and Fallen are at issue respecting 
them : there are, however, characters which are so evident, 
that we can recognize the genus at first sight, viz. the com- 
paratively short wings, the long and convex body, the very 
short thighs and tibiae, the globose head, and the short and 
curled antennae, composed of fewer joints than in most of the 

These insects do not appear to fly much ; they are generally 
found running amongst moss and grass, for which purpose 
their short and strong legs are well adapted. A. debellator has 
been found in Norfolk. A. victor I found last summer near 
Dunkeld ; its red petiole distinguishes it from the former in- 
sect, which has a black one. We have 2 or 3 other species that 
are unnamed. 

The plant figured, Tricntalis europcva (Chick weed Winter- 
green,) was found at the same time.

Two females of this beautiful insect I bred the end of last 
June from some dead bramble stalks that were given to me by 
Mr. F. Smith, with the expectation of obtaining from them the 
Osmia leucomelana, not one of which however made its appear- 
ance, but to my surprise and gratification these Crypti, and a 
few days after some females of Odi/7ierus [Epipone) Icevipes, 
described by Mr. Shuckard in Loudon's Magazine of Nat. 
Hist, issued from the sticks. The Crypti were exceedingly vi- 
vacious, not a joint of their antenna? or legs, or a segment of 
their abdomen being at rest, and they resisted the fumes of 
sulphur under a glass longer than any other insect that has 
come under my observation, whilst, on the contrary, the Ody- 
neri were very sluggish, not attempting to unfold their wings, 
and were easily deprived of life.

Cowes in the Isle of Wiofht, I am intlebted to Dr. Bromfield.

(') The situation of the genus is thus indicated that it may be recorded in the 
Guide ; and whenever it is reprinted, all new or additional genera will be inserted 
in their proper places, with letters attached to the numbers, that those of the first 
edition may not be disturbed. 

In the last Number I had the pleasure of publishing an extra- 
ordinary novelty belonging to the order Strepsiptera, and I 
am happy to commence a new volume with an equally fine 
species of" the order Hymenoptera. 

This curious insect is considerably like Helorus and some 
of the Proctotrupidae at first sight, and not unlike some of the 
Formicidae; and the habit as well as the sculpture of the 
thorax remind us, at a casual glance, of the genus Chlorion ; — 
on examining the mouth however, and wings, it will be found 
to be entirely different. It is undoubtedly one of th.e Ichneu- 
monidae, and bears considerable resemblance to Hemiteles, 
but it has no areolet in the superior wings ('). 

For specimens of this fine nondescript I am indebted to 
Henry Walker, Esq., who took them on the Clyde, near 
Lanark; they were accompanied by the following remarks. 

" I observed the males at the end of May and beginning of 
June, on days when the sun shone bright, skimming over the 
surface of the water, and alighting on humid moss-covered 
stones. Towards the close of the day I subsequently detected 
two females reposing on the same rocks, apparently in a dor- 
mant state." 

A. armatus Walk. — Curtis Brit. Ent. pi. 3S9. Jemale. 

Male, black shining, thickly clothed with very short yel- 
lowish pubescence, minutely punctured; scutellum with the 
tip of the spine ochreous, postscutellum and petiole dull, the 
latter thickly punctured, with two elevated lines down the 
back, and one on each side. Wings transparent, obscurely 
clouded with pale brown, the stigma and nervures piceous. 
Female more robust; the antennae are much shorter, similar 
in colour and sculpture, the spine of the scutellum is entirely 
black ; the wings, especially the superior, are stained yellow, 
clouded with rich brown forming three fascise, the two first 
united at the interior margin, the third running obliquely from 
the stigma, the apex of the same colour, but rather paler. 

They vary exceedingly in size, some being only half as large 
as others. 

The Plant is Scutellaria galericulata (Common Skull-cap). 

(') Since the above was written, I have received a specimen sent by me to Mens. 
Latreille for his inspection. He says : " The antennse, the cibarian organs, and 
partly the disposition of the cells of the wings, rank it with the Ichneumonidae; 
but by the form of the abdomen and the radial cell of the wings it appears to me 
to approach the Oryuri, especially my genus Helorus ; — in a word, it seems to unite 
the IchneumonidaB with the Oxyuri. The ovipositor (terebra), or rather the ex- 
tremity of the abdomen, appears, from the specimen that you haVe transmitted to 
me, more analogous to that of the latter than the former."

/« the Author s and other Cabinets. 

Pezomachus is a remarkable group of ilie Crypti, being either 
apterous or having only rudimentary wings. From Graven- 
horst's description and figure of one of these, it appears that 
they vary in their neuration, and the genus therefore requires 
further investigation in order to form at least natural sections, 
and from the very great dissimilarity in the structure of the 
thorax and the form of the penultimate joint of the tarsi, two 
genera probably might be established, in which case Thun- 
berg's name of Gelis would very well apply to one of them. 

The Pezomachi are equally curious in their oeconomy, for 
although like the rest of the IchneumonidiE they are parasitic, 
they do not seem to be attached to any particular group, if 
the statements made be correct. I have heard of their being 
produced from Spiders' eggs and from the larvfe of Ctircidio 
plajitaginis, and Linnaeus says one species in its perfect state 
lives upon Acari. The two that I have bred, P.festinans Fab. 
and P. vagans Oliv., hatched from the cocoons of two species 
of Microgaster, and with the latter appeared another parasite, 
a species of Hemiteles, and Mr. Haliday in the Ent. Mag. 
mentions two, so that 3 or 4 different Ichneumonidae were pro- 
duced from the .same cocoons. The most remarkable fact 
however relating to these little animals is the great apparent 
excess of females ; I have in my own cabinet upwards of 20 
species, and only know the male of one [P.fesiinans), and Mr. 
Haliday sayshe has seen hundreds of the female oi P .fasciatiis^ 
yet he never met with a male. 

For a list of the species I must refer to the Guide. They 
are found in spring, summer and autumn where reeds abound, 
in sandy districts, in theflowersofSyngenesious plants, amongst 
grass &c., and in winter in moss and under stones. The species 
figured I swept into my net last August, off some bushes of 
Sweet Gale in the Isle of Arran, as we were ascending Goat- 
feld, and I had met with it twice before in Norfolk : the male 
has not been discovered. 

The Plant is Urtica pilulifera (Roman Nettle), from Lowes- 
toft Denes, Suffolk.

The large rhomboidal areolet, connected with the lower ner- 
vure of the marginal cell by a short pedicel, and the large 
curved internal cubital cell, are good characters to identify 
the Mesochori ; and the males of this pretty genus are distin- 
guished by two slender spines at the apex of the abdomen. 

Mr. Haliday has observed to me, in a letter, that this genus 
affords two strongly-marked divisions, — 

L With the interior brachial cell of the lower wings emitting 
a single nervure from its inner angle.

ScHGENHERR having employed Lissonota to designate a group 
of the Cerambycidae, it becomes necessary to supersede Gra- 
venhorst's name, and to assist the memory I have used a 
similar word. 

Lampronota is a subgenus of Pimpla, and is best distin- 
guished by the smoothness of the abdominal segments. 

The following appear to be British species. 
14*. L. crenicornis Hal. — Curt. Bril. Ent. pi. 407. male. 

Mr. Haliday says "it was found from the early part of 
August to the middle of September, and another species with 
similar antennae of the same figure, &c. occurred in a pine- 
wood : it differs in having the coxae black, the hind tibiae and 
tarsi dusky, and it is larger," 

I am indebted to Mr. Haliday for specimens of the remark- 
able insect figured, and he considers it to be almost osculant 
between Lampronota and Phytodietus; from the former it dif- 
fers only in the cleft abdomen of the female and the deep 
thoracic sutures.

Fabricius having drawn his best character for the division of 
Pimpla and Cryptus from a sexual distinction (the form of 
the antennae), it becomes necessary to have recourse to other 
parts to estabhsh them as genera. The only difference we 
shall now point out is the nearly sessile abdomen of Pimpla, 
and the peduncled one of Cryptus, a mark which will be 
found sufficient to separate them. 

By this arrangement the genus Pimpla will be very much 
circumscribed ; nevertheless it will be sufficiently extensive to 
admit of the following sections : 

I. Ovipositor longer than the body. 

* Abdomen slender. 

1. P. persuasorius Linn. — Don. 15. 522. — Beginning of 
July ; about Pine-trees near Manchester, and in a garden in 
Norfolk. Mr. Bracy Clark informs me that he took the females 
upon Pine-trees in Switzerland, and that they were not able 
to extricate their oviduct from the crevices in the bark where 
they were inserted.

The above are the only species that appear to be described. 
It is well known that they all deposit their eggs in different 
larvae ; those with long oviducts in internal feeders, and the 
others in caterpillars of moths : many, if not all the Pimplae 
when taken, emit a very foetid odour. The ovipositor is ge- 
rally considered to consist of 3 parts, but my friend Mr. Tho- 
mas Carpenter has discovered that the central part or oviduct 
is composed of a sheath inclosing 2 filaments ; which gives 
strength, prevents the entrance from being closed when the 
oviduct is placed at a right angle with the body, and enables 
the insect to regulate the passage to the size of the egg : the 
same structure obtains in the Cynipsidae also. 

One of the plants upon which Arctia cccnosa feeds, Butomus 
timbellatiis (Flowering Rush), is given with the Pimpla, which 
is a female.

Peltastes receives its generic name from the face forming an es- 
cutcheon or shield : like the rest of the family these insects are pa- 
rasitic in the larva state, the females depositing their eggs in the 

caterpillars of Lepidoptera ; they begin to feed as soon as they are 
hatched upon the muscles of their victim, until the whole internal 
substance is consumed, excepting the alimentary canal. In this 
diseased state the caterpillar changes to a chrysalis, frequently as- 
suming the natural form, although the colour is sometimes altered; 
but instead of a moth or butterfly, one or more Ichneumonidae are 

This tribe of insects, however, is eminently useful, employed as 
it appears to be, to destroy and keep within bounds those hosts of 
caterpillars which otherwise might frequently deprive vegetation of 
its beauty and utility : to convince the reader of this, it will be only 
necessary to refer him to the " History of the Brown-tail Moth, by 
W. Curtis." 

The following are the species and varieties of this genus : 

1. P. necatorius Fab. Ent. Syst. 2. 144. 45.— Vespoides Panz.fasc. 47. pi. 19. 

Black, thickly punctured. Antennae orange beneath. Clypeus, 2 spots

don : it has been bred from the pupa of Stauropus Fagi. This may 
prove to be the other sex of the following species.

Soc. V. 3. tab. 2./. 5.-/3 Polyzonias Forst. Cent, of Ins. n. 85. 

This is the largest species, and has been taken in June by Mr. 
Bentley and Mr. Dale, near Ringwood, Hampshire, flying amongst 
pine-trees, in the sunshine ; and by the latter gentleman also on the 
heathy side of a mountain near Ambleside, Westmoreland ; and 
var. a was bred from the pupa of Lasiocamioa Trifolii. This 
species, like the rest of the genus (indeed of the family I might say), 
is extremely variable ; some having orange antennae not black above 
as in var. a, others with the clypeus, palpi, and all the thighs black, 
and yellow bands to all the segments of the abdomen ; and in var. /3 
the thighs are ferruginous. Although there is no doubt but this 
last is a variety only of P. dentatus^ as it seems to be a very un- 
common example, I have not adopted Forster's name, which other- 
wise has the right of priority. 

3. P. dissectorius Panz. Faun. Germ.fasc. 98. n. 14. 

Black thickly punctured. Abdomen chalybeous, margins of 4 first joints 
yellow ; legs piceous, thighs partially black. Wings with a fuscous ;>pot be- 
yond the stigma. 

I took a specimen the end of September, 1822, in the North of 
Devon, and have since received another, which is a very strong va- 
riety, being black, with a yellow spot only on each side of the 3 
first segments of the body and a yellow margin to the 4th, and the 
fuscous spot on the wings is very faint.

This remarkable genus is so exceedingly rare that only three 
specimens of the first species have been discovered, and but 
one of each of the others, and the females are unknown, which 
will account for the incomplete description of the trophi, it 
being quite impossible to obtain a specimen for dissection ; at 
the same time I could not resist the temptation of giving a 
figure of the magnificent novelty represented in our plate, 
as it cannot fail to be acceptable to those who admire and 
study the interesting order of Hymenoptera.

Nothing, I believe, is known of the oeconomy of these insects : 
the males are distinguished by short antennae, spiral at the 
apex; the abdomen is generally less dilated vertically at the 
apex, and is often a little incurved.

cimen flying about the plant figured, on the sand -hills near 
Roundstone. I have also received a female from Kinnordy,

Order Hymenoptera. Fam. Ichneumonidae. 

Type of the Genus, Ichneumon circuraflexus Linn. 
Therion Curt. — Anomalon Grav. — Ichneumon Linn., &c. 

Antenna inserted a little above the middle of the face, longer 
than the wings in the male, filiform, composed of innumerable 
quadrate joints, basal one the stoutest, 2nd minute, 3rd the 
longest : shorter and stouter in the female, more tapering to 
the apex, and the joints transverse. 

Labi-urn transverse, semiorbicular, ciliated with long hairs, having 
a minute lobe in the centre (2). 

Mandibles slightly curved, terminating in a strong beak, with a 
long but smaller tooth outside where it is hairy (3). 
Maxillce short, terminated by a semiorbicular ciliated lobe, with 
a smaller serailunate one inside. Palpi very long, pilose and 5- 
jointed, basal joint rather the shortest, 2nd the stoutest, oth 
the slenderest and linear, the apex ovate (4). 
Mentum elongate-ovate. Palpi shortish, pilose and 4-jointed, 
basal joint obovate, 2nd stout, semiobovate, 3rd somewhat 
hatchet- shaped, 4th the longest, slender and subfusiform. Lip 
short and bilobed (5). 
Head transverse, base very concave ; face orbicular-ovate : eyes ovate, 
not large : ocelli 3 in triangle on the crown. Thorax rather short, 
thick and oval : scutel gihbose and semiorbicular or subquadratc : 
metathorax sloping, flat and rugose. Abdomen very long and 
slender, compressed, arched, clavale, carinated above, with distinct 
spiracles down each side : petiole long, slender, cylindric and cla- 
vate, 2nd joint slender : ovipositor short but exserted. (G $ , ter- 
minal segme7its of female ; (^ the same of male.) Wings mlich 
shorter than the body ; superior with a long marginal cell, no 
areolet and a long narrow stigma. Legs slender, anterior short, 
hinder very long : trochanters, hinder very long and b'larticulate : 
thighs simple, clavate : tibiae clavate, spurred : tarsi, hinder with 
2, 3 or 4 of the basal joints incrassated in the viales ; 5-jointed, 
basal joint the longest, terminal one slender, clavate : (8 ^ hind leg). 

Amictum Fab. — Curt. Guide, Gen. 531. 114. 

Male, head with an acute spine in front, black as well as the 
thorax, thickly punctured and pubescent : antennae very long, 
ferruginous, ochreous beyond the middle, basal joint yellow 
with a black line outside, 2nd and base of 3rd yellow beneath : 
face and trophi yellow : abdomen ferruginous, a faint streak of 
black on the petiole and a black shining stripe on the back of 
the 2nd; 4th and following segments fuscous beneath as well as 
the backs of 2 or 3 of the terminal : wings yellowish, the mar- 
gins slightly fuscous, nervures brown, stigma ochreous : legs 
yellowish, outside of thighs and apex of tarsi ochreous: hinder 
legs bright ferruginous, coxae and trochanters yellow beneath ; 
apex of tibiae dull black ; tarsi dilated, basal joint attenuated to 
the base, the following ochreous, 2nd joint robust oval, 3rd but 
shghtly thickened, 4th minute, 5th small and clavate. 

This pretty little group is distinguished from Paniscus by the 
absence of the areolet, and from Ophion (pi. 600.) by its less 

ample and shorter wings, as well as by a striking difference 
in the form of the nervures, where the areolet is situated 
when present, and by the thicker posterior legs, their tarsi 
being generally more or less incrassated in the males; but in 
a new species which I shall describe, and also in T. tenuitar- 
sum^ they are not thickened. 

Having published the genus Anomalon before Graven- 
horst's work appeared, it may appear necessary to give my 
reasons for rejecting some of his names in the Guide. 1st 
Bassus of Fabricius is Gravenhorst's 3rd family of Cryptus, 
seductorius being the type given in the Piezatorum ; 2ndly, 
Jurine's 1st family of Anomalon, which of course is his type, 
Gravenhorst has called Bassus. 3rdly Jurine's 2nd family of 
Anomalon I have called Theuion, because it is not the typi- 
cal Anomalon.

The sexes of Ophion are rather difficult to distinguish, for 
even the abdominal appendages are very similar ; but an ob- 
lique suture, in which the oviduct is secreted, distinguishes the 
females: this oviduct is short and rigid, being well fitted for 
puncturing the skins of larvae in order to deposit the eggs ; 
and from its acuteness and horny substance it seems to be 
equally well adapted for defence. 

It has struck me as very remarkable that one often can ob- 
tain only one sex of Ophion from an infested larva, although 
a considerable number may be hatched : having observed this 
several times it can scarcely be accidental ; I am therefore rather 
inclined to think that one sex appears before the other, and 
that the eggs of each are deposited separately in different 

The following are British species, 2 of which are unrecorded

Mr. Shuckard discovered this rare species in Batterseii 
Fields the beginning of last July, when he took several males 
and two females on the flowers of the garden Parsnep, and by 
his obliging addition of specimens to my cabinet, I am enabled 
to give a magnified figure of the male. Its flight is peculiar, 
resembling that of the Lark. 

It has long since been observed in this work, that the trophi 
cannot be expected to differ much in allied groups, and con- 
sequently that they enable us to generalize and form families 
rather than genera, and this is exemplified in the two species 
of Pachymerus, whose organs of manducation are very similar, 
yet in other respects they vary so greatly, that they cannot be 
included in one genus: the structure of the antennae, the neu- 
ration of the wings, and the dentated hinder thighs in P. viil- 
nerator are characters sufficiently strong to justify its separa- 
tion ; I have therefore applied the name of Pristomerus to 
this species, reserving Gravenhorst's Pachymerus for that 
which has the thickest thighs in both sexes, which I shall now

In the Cabinets of Mr. Davis and the Author. 

Xylonomus of Gravenhorst is distinguished from Xorides of 
Latreille by the abdomen being broader at its base, and sca- 
brous instead of smooth. 

The Xylonomi are so called from their inhabiting wood, 
and like most others that reside in timber in the larva state 
they vary greatly in size in the same species. In fine weather 
the females run over the surface of paling and trees perforated 
by bees and other insects, and investigate the holes with their 
antennae in order to ascertain if they contain any larvae; but 
I have never seen this rare insect deposit its eggs. 

Gravenhorst neither mentions the singular base of the tibiae 
in the females, nor the curious spines towards the apex of their 
antennae, which in the only male I have examined are nearly 
straight, filiform, and very pilose on the underside. 

Two species appear to inhabit Britain, neither of which 
has been figured. 

1. X. pilicornis Grav. — Curt. Brit. 353. fern. 

Male black, slightly pubescent, head sparingly, thorax very 
thickly punctured; postscutel rugose : abdomen rugose, smooth 
towards the apex, 2nd and 3rd joints rufous : stigma and ner- 
vures piceous, the former white at the base : palpi pale fus- 
cous ; anterior legs ochreous, posterior rufous ; trochanters, 
coxae and base of thighs black, hinder tibiae and tarsi brown, 
the former subochreous at the base and tip. Female with the 
12th and 3 following joints of the antennae whitish: abdomen 
rufous, blackish at the apex : ovipositor longer than the body, 
black, oviduct rufous : legs rufous, trochanters and coxae black, 
4 anterior legs variegated with fuscous, hinder tibiae and all 
the tarsi brown. 

I first discovered a male of this insect many years since in

20th of last May on a rail near Hampstead. The fine female 
figured (which is much larger than mine) was taken by my 
friend Mr. Davis, I believe near Gravesend. 

2. X. Gravenhorstii Curtis. 

Male undiscovered. Female 4 lines long, aculeus 2 lines. 
Distinguished from the last by its short antennas and ovipo- 
sitor, and by its more slender form ; the base and tip only of 
the abdomen are black ; it is smooth, not rugose, and the lon- 
gitudinal lines at the base are scarcely visible. 

I have taken two females of this nondescript near London, 
and have dedicated it to the distinguished Professor whose 
elaborate work has enabled me to study this curious and ex- 
tensive family, of which I possess upwards of 400 British 

The plant is Briza minor (Small Quake-grass), found near 
Poole, Dorsetshire, by the Hon. C. A. Harris.

Although there are a considerable number of minute species 
witli transparent wings which are comprised in the genus 

Bracon, it will be found that they do not well agree with the 
characters of the larger ones with opaque wings, which appear 
to be universally distributed, being found as far south as the 
Cape of Good Hope, from whence we receive a variety of 
beautiful species ; on the continent of Europe there have been 
several detected, but we can claim but one at present in this 

Mons. Latreille has observed that the mouth is produced 
in the form of a rostrum, like Agathis : it appears to me that 
the lip and maxillae unite, so as to form a short proboscis ; 
but this is not easily discoverable in dead specimens, except 
by dissection. The same author has described the labial palpi 
as 4-jointed, but I am inclined to agree with Fabricius, that 
they have only 3 joints. I would wish here to remark, that 
the costal nerve is continued round the wing, and not termi- 
nated near the apex, as is common with the Ichneumonidse ; 
that the submarginal cells are complete, but the last transverse 
nerve is less strong than the others, especially in the female ; 
and that the 1st submarginal and two discoidal ceils, which 
are nearly of equal size, form a regular hne across the supe- 
rior wings : indeed so great are the differences of structure, 
as well as economy of Bracoji and its congeners, that it is pro- 
bable when further investigated and better understood, they 
will be found to form a natural and extensive family. 

The male of Bracon Denigrator, it is presumed, is very rare 
even upon the continent, otherwise it would have been figui'ed 
with the other sex. That which is here represented, was 
taken last year in Birchwood, Kent, and is now in the posses- 
sion of Mr. Stone; and the only female that I have seen, was 
captured by the Rev. W. Kirby, and is now in Mr. Stephens's 
fine collection. Panzer in his Fauna Germanica,fasc. 45. n. 14. 
has figured this sex. 

Fabricius says, that it frequents gardens upon the continent, 
where it appears to be not uncommon ; and Latreille informs 
us, that the female deposits her eggs in the fruit of plants, es- 
pecially thistles. 

The plant figured is Cichorium Infyhus (Wild Succory).

Neglected as this extensive family has been, it is not to be 
wondered at that we are but ill-acquainted with the affinities 
and economy of many of the groups composing it : as every 
fact is therefore rendered the more valuable, I have the 
greater pleasure in presenting my readers with the present 
species, which I captured in the New Forest about a mile to 
the north of Lyndhurst. We were resting ourselves about 
noon in the early part of September 1822, whilst the sun 
shone very powerfully, when I observed one of these pretty 
insects flying over the flat surface where a tree had been felled, 
upon which it settled; and shortly after two others appeared. 
They all hovered over the block and at intervals lighted upon 
it, but I could not observe that the female deposited any eggs ; 
and knowing it to be a rare insect, new to Britain, I was fear- 
ful of losing it, which prevented me from further observing 
its operations. I consider myself most fortunate in capturing 
both sexes, as the males of this family are very seldom known; 
and Panzer having only figured the female, the male is here 
represented in preference, and the body of the female is given 
at the bottom of the plate. 

Latreille's genus Ichneumon, comprising most of the genera 
into which Fabricius had divided it (although very imper- 
fectly), must be considered as a family, since it is impossible 
to include insects in the same genus so widely different as 
Peltastes (plate 4.) and our present subject, Bassus ; and 
although the long exserted ovipositor gives it the appearance 
of a Pimpla, it will be found to be much more nearly allied 
to Microgaster and Agathis. 

There are probably about 15 British species in our cabinets 
allied to that figured, but I think only 4< or 5 of them per- 
fectly agree with our type, and I believe none of their names 
have yet been ascertained. 

Vaccinium Myrtillus (Bilberry), growing in abundance 
where the insect was taken, has been selected for the plate.

This natural group, which was distributed by Fabricius, has 
been formed into a genus by Latreille, but has never been 
described as British. Like the rest of the Ichneumonidae 
these small insects deposit their eggs in lepidopterous larvae, 
and one of them is particularly useful in destroying the cater- 
pillar of the Cabbage Butterfly [Poiitia Brassiccs). There 
must occasionally be myriads of these little Ichneumonidae, 
for we frequently see large clusters of beautiful silky cocoons 
attached to a single caterpillar, and those whose cases form a 
sort of honey-comb produce vast quantities. 

Microgaster is nearly related to Bracon and Bassus. The 
following British species may be thus divided.

This genus was established by Nees von Esenbeck, who placed 
it between Perilitus (which follows Aphidius) and Bracon; and 
Mr. Haliday, in his learned Essay on the Parasitic Hymeno- 
ptera, locates it between the same groups. Our Leiophrons 
are easily distinguished from the other IcJmeumones minuti, by 
the extremely short and sublunar marginal cell, although they 
are undoubtedly closely allied to the Braconidae. 

I shall describe the few species recorded in my Guide, ^s 
well as two others, and regret that space will not allow me {o 
add some that Mr. F. Walker has obligingly transmitted to 
me. Mr. Haliday calls his division A. Pygostolus, of which 
Crypus sticticus Fab. is the type; it is characterized by "the 
radial areolet just touching the apex of the wing," The next 
is B. Radial areolet very short, semilunate.

From the great resemblance these insects bear to the Bra- 
conidse, 1 placed this group in my Guide between Bracon and 
Agathis, but it is evident from the 6-jointed maxillary palpi 
that it belongs to that extensive sub-family which may now be 
termed Alysiidse. The typical species are characterized by a 
perfect trapezoid cell on the costal margin of the inferior wings, 
and also by the minuteness of the 3rd joint of the labial palpi. 
The following are British species, and Mr. F. Walker has 
several others which he found on grass in meadows at South-

In the Cabinets of Mr. Rudd and the Author. 

Hecabolus is evidently nearly allied to Spathius, in which 
group it is included in the Guide, but the shorter and stouter 
antennae and the absence of the petiole to the abdomen dis- 
tinguish it from the latter genus; the male is also characterized 
in a very remarkable manner, having a stigma on the costa 
near to the base of the inferior wings, similar in substance and 
colour to those in the upper wings, and filling one of the cells, 
which is open in the other sex. 

Many years since I discovered a female of this curious 
insect in Norfolk, and afterwards both sexes on a post very 
much perforated by insects in a Garden at Fulham; they were 
entering the holes with Heriades (1 believe), Pemphredon, 
Crabro, Ptilinus, &c. 

I am also indebted to the Rev. G. T. Rudd for specimens 
which he found on an old ash post in Yorkshire. He states 
to me in his letter that they were confined to one spot and 
post, and were evidently parasitic on the genus Ptilinus, and 
he has lately informed me that he discovered dead specimens 
of the Hecabolus in the pupae-cases (which they completely 
filled) of Ptilinus pecihiicotfus, and also the CheirojmcJms qua- 
drum {Cleonymus maculipeimis of this work, folio 194.) in pro- 
fusion in the pupas-cases of Hyle sinus Fraxini, thereby con- 
firming the remarks made by Mr. Cooper in the Entomolo- 
gical Magazine. 

For specimens of the rare plant figured. Daphne Mezereum 
(The Mezereon), I am indebted to J. C. Dale, Esq., who pro- 
cured them the beginning of last April from Cranbourn Chase,

Li the Cabinet of the Author. 

Alysia approaches very near to Bracon, especially in the 
structure of the wings, which are however ahke in both sexes ; 
the labial and maxillary palpi have a joint more than those of 
Bracon, and its tridentate jaws so remarkably situated, at once 
distinguish it from all other genera. 

Of this singular genus only one species appears to have 
been described, and that has never been recorded as British : 
we have had the good fortune to discover eight others of which 
we shall give short descriptions, first observing that all, ex- 
cepting No. 6, are black and shining, with ochraceous legs.

A. Manducator is not uncommon upon umbellate plants in 
meadows, the dung of animals, &c. 

A. PratellcE. Found with some Cynipsidcc the end of Sep- 
tember in the park of Heron Court, Hampshire, by my 
esteemed friend the Hon. Charles A. Harris, who disco- 
vered them concealed between the collar and gills of very 
young mushrooms. 

A. Apii. For specimens of this insect and their history I am 
indebted to a lady who found the larvae feeding upon 
the parenchyma of celery leaves the 30th Sept. ; on the 
11th Oct. they had changed to shining oval pupae of a 
dull ochre colour, having very much the appearance of a 
shell [Turbo Chrysalis oi Turton); the imago appeared 
the June following. 
Our insect receives its specific name from the genus of 

plants to which it is destructive; and Apium graveolens (Wild 

Celery) being an indigenous species, it is figured in the plate.

In the Cabinets of Mr. Haliday and the Author. 

Since the genus Alysia was illustrated, the present group has 
been discovered by Mr. Haliday, to whose liberality I am in- 
debted for the species I possess; and Mr. F. Walker has fa- 
voured me with his collection, to enable me to arrano-e and 
give slight characters of the whole. ^ 

The species have been taken by the former gentleman in 
Ireland, from July to September, in moist meadows, and by 
the latter near Southgate as early as the end of June. The 
length of the antennae is probably only a sexual character, and 
I suspect the species depart considerably from the type, in the 
form of the female abdomen, and one is destitute of wino-s

Li the Cabinet of Mr. A. H. Haliday. 

These little insects are parasitic, and live in the female 
Aphides : we sometimes see their horny bronzed cases stick- 
ing to the leaves of roses and other plants, with a round hole 
on one side and the lid frequently hanging like a door on its 
hinges, as represented in Harris's Exposition, tab. 18. f. 10. 
from these some of the little Ichneumons or their minuter 

destroyers have escaped, for these again have their parasites 
as we learn from Geoffroy, who states that a Cynips destroys 
the larvae of the Ichneumon des Peucerons (Aphidius), and 
from his description I think it may be my Ceraphron Carpen- 
teri (folio 249* No. 10), which I there stated had been bred 
from the Aphides by the late Mr. Carpenter. 

I am indebted to Mr. Haliday for a valuable monograph 
containing 19 species of Aphidii ; and Mr. F. Walker tells me 
he thinks he has about 50. It being therefore impossible to 
give specific characters of the whole, I shall avail myself of 
Mr. Haliday's paper, and give his admirable divisions. 

* Wings with 3 cubital areolets (Div. 1. Nees). Radial areolet termi- 
nating at the apex. Head small, rather globose. Antennse shorter than 
the body of 11 joints in both sexes. Aculeus short compressed, a little 
curved upwards. 

* * Wings with one cubital cell effuse to the margin, distinct from the 
anterior of the disc (Div. 3. Nees). Wings very ample, the radial areolet 
effuse, including the whole apex. Antennae and legs long and extremely slen- 
der. Head small globular narrowed to the back. Palpi long and slender. 

Mr. Haliday has described 4 species of the first division, 
and 3 of this, but has given no names, and I have none of them. 

* * * Wings with the anterior cell of the disc and inner cubital confluent 
and sometimes both together open to the margin (Div. 2. Nees). Head 
more transverse than in the other divisions. Radial cell terminating at 
the apex, its interior nervure often vanishing before the apex. 

a. Valves of the aculeus compressed, straight or curved upwards, black 
(Antennae longer in the males, varying in the number of joints, more nu- 
merous in the same sex : middle cell complete or open only to the exterior 
cubital one). 

This division contains A. Pini Hal., the males taken on 
the larch in Aug. the females on the Finns sylvestris in Sept. 
— infulatus Hal. on the larch in Aug. — pictus Curt, on the 
Scotch fir, Sept. — dimidiatus Curt. — Rosae, Hal.? — picipes 
Nees, infests the Aphides of Hieracium ? — fumatus Hal. 

b. Valves of the aculeus incurved, broad, generally securiform, pale, 
f Anus beneath unarmed. 

1. The middle areolet defined posteriorly. 
Contains two unnamed species. 

2. The middle areolet entirely eftuse to the margin (species very minute). 
Contains two species, and probably A. basalis Curtis^s Guide. 
ft Anus beneath in female armed with 2 diverging horns recurved at 

the end, longer than the aculeus which lies between them. Middle areolet 
effuse. Antennae in the females of 1 1 joints, rather thicker towards the apex. 
Contains A. letifer .H«Z.^ — A. minutus Curt. — A. constrictus 
Hal., and another. 

The insect figured may be the I. Aphidum Linn.: but as 
the specific name has been converted into one for the genus 
by Nees ab Esenbeck, I have given it the name of ' Cirsii ' 
from its being said to be parasitic on the Aphis Cirsii, so 
named from its inhabiting Cirsium arvense Lam., the Carduus 
arvensis of this Work, PI. 296.

The genus Ibalia contains at present, I believe, no other species 
than Cultellator, and was never known to inhabit Britain until the 
male represented in the plate was captured flying in a garden at 
Bungay, Suffolk, by Mr. W. H. C. Edwards, justly celebrated for 
his masterly engravings and knowledge of the fine arts. It is also 
found in Germany and the South of France. M. Latreille found 
it in the environs of Brive, in a wood of old Horn-beams, vaulting 
round some of the trees, in the month of May : M. Foudras also 
takes it near Lyons. The economy and habits of this genus are 
supposed to be similar to the rest of the family, forming galls upon 
various plants. 

The eccentric structure of the third joint of the antennae in the 
male at once shows that Ibalia belongs to the Diplolepida;'^, of 
which family it is the largest species; the second submarginal cell 
is so minute, that it is scarcely discernible through a lens; the 
hinder legs in both sexes are very powerful, and exceedingly dis- 
prqportioned to the body and other legs, which are remarkably 
small. Ibalia is nearly allied to Cynips (pi. 688), but it is readily 
distinguished by the length of the abdomen and the neuration of 
the wings. The singular spine on the second joint of the hinder 
tarsi of both sexes, as well as the puncture or spiracle on the side 
of the abdomen, has hitherto, I believe, escaped the observation of 

It may be here observed, that the mandibles are often not coun- 
terparts of each other, tlie shape being adapted to their close con- 
tact when at rest; other parts of the mouth are also sometimes ir- 
regularly formed. The student must not be misled by these excep- 
tions, which are most frequent in the Hymcnoptera^ occasionally 
in the Coleoptcra, and probably all the Mandibulat(e.

This group of insects, called Gall-nut flies, deposits its eggs 
in the leaves, buds, stalks, and even in the roots of plants, 
thereby forming the various and curious galls which are com- 
monly found upon the oak and other trees, rose bushes, &c. 
One of them, C. Gallcs-tiiictoricB, is the origin of the Oak-gall 
in Asia Minor, which is employed in making ink, dyeing, &c., 
and another, there is little doubt, is the author of the bitter 
apples alluded to in the Old Testament. Protected as the 
larvae are in the heart of a hard ball, they are not secure from 
the attacks of other Hymenoptera, which by means of their 
ovipositors are enabled to pierce the galls, and lay their eggs 
in the tender larvae, so that instead of the Cynips alone, a 
tenfold greater number of Callimome (fol. 552.) and Ichneu- 
monidaD often issue with them from the galls. 

The abdomen of a female that I dissected was filled with 
eggs; the oviduct was attached near the superior angle and 
curved vertically towards the base, and was exserted under or 
between the laminse at a short distance from the ventral sheath. 
Roesel has given figures of the Galls, larvae, pupae and imago 
in pi. 35, 36, 52 and 55 of vol. iii. The following species

In the Cabinets of Mr. Walker and the Author. 

Galesus is characterized by the peculiar form of the antennae, 
and by the remarkable head and distinct petiole ; and it may 
be observed that the Psili of Jurine, which are the Diaprise of 
Latreille, vary from our genus in having the third joint of the 
antennse long. 

In dissecting this insect, the curious scales vi'hich cover the 
base of the superior wings attracted my notice; they are thin 
and moveable, and may be used in closing the large wings, 
which for want of strong nervures, probably require iheir as- 
sistance. The dilated spine at the apex of the anterior tibiae, 
and the beautiful pectinated basal joint at the tarsi, although 
common in the Hymenoptera, are seldom more developed. I 
have now little doubt that they are for the purpose of clean- 
ing the antennae ; few insects are without a spine to the ante- 
rior tibiae, and the basal joint of their tarsi is generally hol- 
lowed out inside, if it be not always pectinated in this order. 

Three species only have been discovered ; Mr. Haliday 
thinks the third may be a small variety of the second. 

1. G. fuscipennis Curtis Brit. Ent. }-)l. ^41. male. 

Smooth, black and shining, partially covered with yellowish 
pubescence : antennae as long as the wings in the male, with 
the fourth and following joints elongated: eyes castaneous: 
ocelli pale : scutellum rugose : petiole with five very elevated 
longitudinal lines: wings pale, fuscous, yellowish towards the 
base, superior, with two white, and two or three brownish lon- 
gitudinal lines on each ; a callous spot below the apex of the 
subcostal nervure, and the curved one near the base, yellow- 
ish brown : base of thighs, tibiae, and tarsi castaneous, the 
hinder tibiae with a dark spot below the middle and the tips 
of the tarsi black. 

The male figured I took in Norfolk many years since, and 
Mr. F. Walker finds it amongst grass in woods near South- 
gate, in June and July. 

2. G. cornutus Panz. 83. W. female. 

Antennae shorter than the wings in the male, having the 
fourth and following joints subovate, excepting the apical one 
(f. 1.): wings very pale, yellowish-luscous: petiole with five 
faint elevated lines : base and tips of the thighs castaneous, all 
the tibiae blackish in the middle, the hinder pair and the tarsi 
castaneous only at the base. 

Males taken in February and April, in shady places ; and 
females beginning of July, on the sea-shore at Holywood, by 
Mr. Haliday.

In the Cabinet of Mr. Holiday, 

Belyta and Cinetus are so much connected, and the females 
are so similar, that until we have the sexes of the different 
species it will be difficult to determine whether the genera 
ought to be separated or united. Jurine distinguishes Ci- 
netus by the triangular costal cell, and the antennae of the 
males are 14-jointed, those of the females 15-jointed. Since 
the plate was engraved I have availed myself of Mr. Haliday's 
papers, and I have scarcely any doubt that the fig. 1 a, belongs 
to Jurine's genus Belyta; I have therefore not incorporated 
the characters of this sex in the generic description, but I 
strongly suspect some of the females have antennae very similar 
to the figure above alluded to. 

The following species have been already detected in Britain, 
although only one has ever been recorded, except in the Guide, 
and there is no figure of the genus, I believe, in any work, 
British or foreign.

In the Author s and other Cabinets. 

Helorus is a genus that does not appear to be immediately 
connected with any that have been at present discovered, for 
the neuration of the wings reminds us of Cynips ; the peduncu- 
lated body, of Agriotypus (pi. 389.); and the structure of the 
mouth shows an affinity to Bethylus, to which genus I believe 
Mr. Haliday thinks it most allied ; indeed there can be no 
doubt of its belonging to the family of Proctotrupidas ; but it 
may be at once distinguished from all its congeners by the 
curved nervure, forming, as Jurine observes, a horse-shoe in 
the centre of the superior wings. 

The portion of the mouth figured as the labrum, may be 
only an appendage to it, but it was all I could discover, and 
I had only the opportunity of dissecting one specimen ; I be- 
lieve a similar lobe is exserted from the mouths of the Bethyli. 

Mr. F. Walker showed me some specimens which I sus- 
pect are the males of our insect ; they are more slender, the 
antennae are brown or ochreous, the wings transparent, the 
peduncle much more slender than in my specimen ; the body 
is more acute, the legs are very slender and ochreous, with 
black coxae, and the posterior thighs are brown, except at the 
base and apex. 

It is not improbable that the H. ater represented in Jurine's 
14th plate may be nothing more than a variety of H. anoma- 
lipes with the legs entirely black ; for in one of Panzer's figures 
all the thighs are black, and I have a specimen in which only 
the tips of the anterior thighs and their tibiae are ochreous. 

Helorus is by no means a common insect; I took speci- 
mens many years since in Norfolk, and Mr. Kirby has ob- 
served it in Suffolk ; Mr. F. Walker takes it at Southgate in 
a marshy meadow in August ; Mr. Dale has found it on Parley 
Heath, Dorset; and Mr. Haliday sent me a specimen from 
Belfast ; he detected it in a marshy field at Holywood.

It was the opinion of Latreille and Esenbeck that Proctotru- 
pes is allied to Helorus (pi. 403), and Mr. Haliday considers 
that it connects Diapria (Psilus) and Ceraphron (pi. 24'9). I 
must confess I expected to find it related to Cynips, and being 
unable to enter upon its affinities, I shall pass on to an ex- 
amination of the ovipositor, which offers some peculiar cha- 
racters. In the Ichneumonidae this organ is either porrected 
or elevated, but in ProctoLrupes it is deflexed. Like that 
family, however, it has 2 sheaths inclosing a compound ovi- 
duct composed of 3 pieces, as shown in Pimpla (pi. 214. f. 6), 
but in Proctotrupes these are acuminated, and the lateral ones 
have their points securely fixed in the central one, the apex 
of which forms a cap for them : the most remarkable part of 
the structure, however, is an additional valve a little longer 
than any of the others, rather broad and membranous, with 
a thickened rib down the middle, the apex rounded (fig. m.) : 
never having seen more than 5 pieces in any ovipositor inclu- 
ding the sheaths, I cannot at present determine its functions. 
I rejoice to see that Mr. Haliday has commenced publish- 
ing Monographs on the Oxyuri, as they will enable those en- 
gaged in the study of these minute Hymenoptera to derive 
every advantage from his elaborate investigations. The fol- 
lowing sections and species form his 1st fasciculus.

In the Cabinets of Mr. Holiday and the Author, 

Nature, ever fertile in her resources, having dispensed with 
one claw in the anterior feet of the males (at least in the spe- 
cies of which there were duplicates to examine), — to supply the 
deficiency, has produced the base of the terminal joint exactly 
as if a second claw was bent back as in the apterous sex, and 
soldered to that joint ; it would appear therefore that the means 
of capturing their prey are curtailed ; but the power to retain 
it is probably increased. Like the genus Proctotrupes, the 
abdomens are acuminated, which give them all the appearance 
of females. 

The following species (with the exception of the first and 
last) were taken by Mr. Haliday in Downshire near the Bay 
of Belfast, " on grass in open groves and the adjacent meadows, 
from the 4th of June to the middle of August. "When in the 
net they ran with uncommon activity, the chelate ungues re- 
maining reflected on the tarsus."

I MUST confess that after great pains I am unable to satisfy 
myself as to the affinities of Bethylus, but I believe it to be 
most nearly allied to Ceraphron, fol. 249. Latreille places it 
amongst his Proctotrupii in the Gen. Crust., and says the an- 
tennas are 1 S-jointed in both sexes, that the maxillary palpi 
are 6-jointed, and the labial 3- or 4-jointed ; in his Fam. Nat. 

he includes it in his tribe Oxyuri, under the same section as 
Dryinus. Nees ab Essenbeck says the antennae are 14-jointed 
in the males, that the maxillary palpi are 6- and the labial 4- 
jointed. Jurine considers the antennae to be 13-jointed in one 
sex and 12-jointed in the other. Now it is very remarkable 
that none of my specimens agree with any of the above charac- 
ters, the antennas being all 12-jointed, and the palpi 5- and 2- 
jointed; how these incongruities are to be reconciled I know 
not. There are as great differences of opinion respecting the 
species ; for whilst some describe several, others view them as 
mere varieties : from the different situations in which I have 
found them, and from the variety of colour in their antennae 
and legs, I shall distinguish them as species. Mr. Haliday 
has ascertained that the Bethyli secrete the larvae of Lepido- 
ptera in broken reeds which occur on sand-hills, for the pur- 
pose, it is presumed, of supporting their larvae. The perfect 
insects are much attached to Syngenesious flowers, sallows, 
roses, grasses, &c. 1 must not omit to observe, that Epyris 
cannot be included with the Bethyli.

Sparasjon was unknown as a British insect until I had the 
good fortune to capture a specimen at Black Gang Chine in 
the Isle of Wight, the 16th of August 1828, but I have never 
been able to meet with it there since. 

The 12-jointed antennae, and the minute 2nd joint of the 
maxillary palpi, are sufficient to distinguish Sparasion from 
Ceraphron, to which it is closely allied on the one hand ; but 
whether it be so nearly related to Bethylus on the other, I 
am not able at present to determine. The membranous 
appendage also to the maxilla?, ciliated along its concave 
margin, I have never observed in any other insect that I 
have dissected. 

I shall here take the opportunity of observing, that with 
very few exceptions, I shall limit myself to the illustration of 
those genera of the minute Hymenoptera which have been 
established by Latreille, so that a very considerable number 
of those recorded in my " Guide" will not be published in 
this work; by which means the Student will be put in posses- 
sion of the leading characters, to enable him to extend his in- 
vestigations further if he chooses, and this work will not be 
carried to an inconvenient length. I beg however to acknow- 
ledge my obligations to my esteemed friends Mr. Haliday and 
Mr. F. Walker for their generous and valuable assistance ; 
and I hope they will be induced to give naturalists the benefit 
of their researches in the two families they have so success- 
fully studied, by publishing the characters of the genera and 
species of these minute but beautiful tribes, of which Mr. Hali- 
day has made most admirable dissections, and Mr. Walker 
has formed a collection embracing at least 700 British species. 

The minute Hymenoptera are best collected by beating 
into, and sweeping with, a net made of fine gauze, and Mr. 
Haliday recommends me to collect them into quills, and after- 
wards to empty their contents into hot water, by which means 
their wings are naturally expanded ; then by introducing a 
card under them to take them out of the water, arranging the 
legs and wings when necessary with a camel's hair pencil, and 
leaving them upon the card till they are dry, they may after- 
wards be taken off with a penknife, and gummed upon the 
points of small pieces of drawing- or card-paper of a long tri- 
angular form. 

The plant is Galium vemm (Yellow Lady's Bed-straw).

So little are these minuter Hymenoptera understood, that 
this genus has never been recorded even as British ; and it is 
remarkable that only one species has ever been described by 
continental writers. I have now seen upwards of sixty species 
taken by Mr. Haliday, Mr. F. Walker, and myself. It is 
evident that they do not vary in figure and character less 
amongst themselves, than they do from the typical form, as 
will be shown by the following divisions with which Mr. Ha- 
liday has kindly furnished me. The insect dissected I pre- 
ferred to the type, not only because it is the largest of the ge- 
nus, but from my being acquainted with the sexes.

trigonate or suborbicular. The Antennae shorter, the 
scape longer and the apex incrassated in the females.

There cannot be a greater proof of the general neglect of the 
Hymenoptera in this country, than the fact that this numerous 
and interesting genus of insects, which has been described and 
published by Latreille upwards of twenty years, has not been 
even recorded as British in any of our works, excepting the 
*' Guide." Nineteen species are there named, and in Mr. Ha- 
liday's collection alone I have seen fifteen others undescribed. 

The remarkable margin to the body beneath, forming a 
sharp edge, is common to Scelio, Sparasion, Teleas and Pla- 
tygaster. From these genera Teleas is distinguished, by having 
a costal instead of a subcostal nervure, which terminates in a 
short branch in the superior wings. In Ceraphron the large 
stigma to the wings will characterize the greater portion, and 
the whole are separated from Teleas by their 5-jointed maxil- 
lary palpi and 11-jointed antennae. 

From Mr. Haliday's observations it appears that the genus 
may be thus divided : 

I. With a punctiform stigma, situated beyond the middle 

of the wing. 

1. T. varicornis Hal. — Is found in sandy places. 

2. T. elatior Hal. — Brit. Ent. pi. 333. — Taken in June by 

Mr. Haliday on marshy ground.

ScELio Is another of Latreille's genera which has not been 
recorded in any British work excepting the " Guide to an 
Arrangement of British Insects ;" with the continuation of 
which I shall now proceed, I hope, without further delay. 

Scelio bears a considerable resemblance to Sparasion 
(plate 317), but is distinguished from it by the 10-jointed an- 
tennas of the male, as well as by the form of the maxillae and 
their palpi. I have been able to detect by dissection twelve 
joints in the antennae of the female (fig. 1. a.) ; and having at 
the same time extracted the ovipositor, no doubt can remain 
of its being that sex : this, as well as the third joint of the 
labial palpi, were apparently unknown to Latreille. 

There is but one species belonging to the genus Scelio : I 
first took a male near Niton, in the Isle of Wight, the middle 
of September 1826 ; and Mr. Francis Walker has since found 
a female upon a window at Southgate, in the month of July. 

Scelio rugosidusy as well as Spat-asionfrontale (lately figured), 
is found in the neighbourhood of Paris, generally upon the 
ground in fields. I took a specimen of the latter insect upon 
a wall near Marseille, the end of last June. 

The plant is Cheirantlius fruticulosm (Wall-flower), from 
Dover Chffs.

The injury done to the wheat in 1795 by the Tipula Tritici 
(Cecidomyia B. E. 178) led to some valuable and interesting 
observations published in the Linnean Transactions, whence 
we learn that one, if not more, species of Platygaster are 
destined to prevent the too extensive increase of the Tipulae. 
As it would be impossible to do justice to Mr. Kirby's remarks 
without transcribing the whole of his papers, we shall recom- 
mend the perusal of them as well to the agriculturalist as to 
the naturalist and philosopher. 

Mr. Walker has captured 50 species of this genus, and Mr. 
Haliday has favoured me with the loan of his collection, and 
proposes the following divisions.

bristles, the margin beautifully ciliated with long hairs ; inferior 
rudimentary only : terminal joint of tarsi fuscous. 

In the Cabinets of Mr. Walker, Mr. Haliday, and the Author. 

Amongst other peculiar characters that mark this group, the 
tetramerous tarsi, and the structure of the wings, especially 
the inferior, which in some species form only a rigid nervure, 
must not be overlooked. In dissecting the head 1 discovered 
a mandible which was tridentate as represented in the plate, 
and I thought I could distinguish a mentum and maxillae, but 
not a vestige of palpi. 

These singular little insects are not unfrequently found on 
windows, where Mr. Dale has captured many curious species. 
Mr, Haliday has formed them into a genus, and Mr. F. Walker 
has favoured me with the following outline of his views on the 
arrangement of the British species.

Spalangia is an interesting group, distinguished from all the 
other pentamerous Chalcididae by its biarticulate palpi. The 
allied genus Cerocephala being apterous is readily distin- 
guished from the typical Spalangise, and the very minute and 
imperfect labial palpi of Pirene form the essential character 
of that curious genus. Mr. Haliday observes that this group 
has a slight resemblance in habit to Megaspilus (Ceraphron, 
pi. 249). It having appeared to me that this insect would 
connect the Oxyuri or Proctotrupidae with the Cynipidae or 
Chalcididae, I placed it between those two extensive groups 
in my Guide ; but the difficulties attending a natural arrange- 
ment of such unlimited families have led to a variety of opi- 
nions concerning their affinities. It seems to me that there 
are ^ species of Spalangia, and I very much regret not having 
received the nondescripts in time to figure one of them.

Mr. Kirby having but one specimen of the male, the legs of 
which I could not clearly see, and having kindly given me 
females which I could relax, I have drawn the latter sex of 
this pretty and rare insect, which perfectly agrees with the 
former excepting the simple antennae, the spot on the posterior 
thighs, and a slight cloud upon the wings. I could not (from 
the same cause) satisfy myself perfectly of the club of the an- 
tennae being composed of 3 joints in the male as I did in the 
female, neither do I feel positive that the branches are not 
articulated. The extreme minuteness of the mouth prevented 
me from obtaining the labrum and mandibles, which I was 
very anxious to accomplish as the Cynipsidce are less com- 
plete in their organization than most of the Hymenoptera ; 
their wings are nerveless, and their palpi and tarsi composed 
of fewer joints than usual. 

Mr. Westwood having discovered a new species, the de- 
scription of which he has obligingly communicated as well as 
some useful remarks, and having another nondescript in my 
own cabinet, I shall give a short account of all the species.

In the Cabinets of Mr. Samouelle and the Author. 

This singular and extensive genus is distinguished from the 
other Cynipidas by the branch of the wing springing from the 
apex of the subcostal nervure, as well as by the long spurred 
intermediate legs. In this genus the form of the antennae is 

not a sure guide, for not only do they frequently vary exceed- 
ingly from the type, but those of the male are sometimes very 
dissimilar to the female. 

Mr. Haliday, to whom I am so much indebted for his va- 
luable contributions and information, distinguishes Encyrtus 
by its minute scapulas and transverse frsena, almost concealed 
by the dorsolum. From his dissections I see that the man- 
dibles of his JLncyrtus Coniferce are tridentate, and his genus 
ERicYDNUS is characterized by "compact fusiform antennae. 
Wings vi^itli the subcostal nervure branched towards the apex. 
Abdomen beneath compressed, acuminate." 

I must refer to the " Guide" for a list of the British species 
amounting to 28, only one of which has even been recorded by 
any other English writer. 

1. E. scutellaris Dalm. in the Stockholm Trans, for 1820.

v. E. Vitis Curt. Brit. Ent. jjI. 395. 

Aide: dull black, slightly pubescent and punctured ; antennae filiform and 
very pilose, terminated by a slender club; ochreous, 2nd joint and the club 
blackish : head with large punctures : scutellum with a tuft of hair at the 
apex : abdomen with the membrane at the base whitish : wings iridescent, 
transparent, nervures subochreous, costal one brown : legs ochreous, pos- 
terior pair compressed, blackish, inside of the thighs, tibiae and central joints 
of tarsi ochreous. 

Female: reddish orange, slightly pubescent and punctured : antennae with 
the flagellum compressed and gradually dilated to the apex which is black, 
and truncated : head sparingly punctured with large shallow impressions : 
scutellum with a black tuft of hairs at the apex, the sides beneath brown : 
abdomen reddish brown : wings transparent, superior clouded with fuscous 
beyond the middle ; nervures, a spot before the middle and the stigma 
brown : tibiag, intermediate brown at the base, posterior compressed, the 
outer edge blackish, the tarsi brown at the base and tip. 

For specimens of this insect and the following observations 
I am indebted to Mr. Samouelle, who bred them from the 
Coccus of the Vine, and has no doubt that the black one, 
which is much the rarest, is the male ; this somewhat resembles 
the E. hirticornis^ and the female the E. Sis^ederi of Dalman. 

" Found on the Vine in Lambeth, July 9th and 10th, 1830. 
These insects settle on the underside of the vine-leaves during 
rain, and on the upper surface when the sun shines; they are 
fond of door-posts, and seem to seek the heat. I also find 
them in the house on the windows ; they leap well, at least a 
foot at a time : the antennae, when the insect is active, are ap- 
plied alternately to the object on which it rests."

ceeded such important differences presented themselves, that I 
found the formation of 2 genera would be unavoidable, and

The trophi of these insects agree best with those of Calli-

but in habit perhaps they make a nearer approach to Eupel- 
mus, especially in the formation of the intermediate legs and 
slightly exserted ovipositor, but these are points which must 
be left for Mr. Walker to decide as he advances in his Mo-

The trophi of Cleonymus are so very similar to those of Colax, 
that we should not have established the latter genus had not 
other characters presented themselves : it is true that the man- 
dibles of the former are stronger and have but two distinct 
teeth, and the terminal joint of the maxillary palpi is shorter 
and more dilated; but on comparing the males of the two 
genera, more decided characters will be found to distinguish 
them, and such we trust as will fully justify their separation. 
The males of Colax are marked by a very large head, a ring- 
shaped prothorax, an obovate abdomen and slender thighs ; 
the same sex of Cleonymus has a moderately-sized head, a bi- 
lobed prothorax, an obconic and thick abdomen, and robust 
anterior and incrassated posterior thighs. We regret that the 
want of female specimens has prevented us from perfecting 
our specific descriptions, as well as from entering into a 
further investigation of that sex, than to observe that the ab- 
domen is longer, more depressed and less compressed and an- 
gulated beneath than in the genus Colax, and that the female 
antennae (at least in the specimens before us) are thickened 
gradually to the apex ; they have not the ring-shaped third 
joint which that genus has, nor do the three last joints form a 
distinct mass. 

So completely have these insects been neglected, that very 
few species of Cleonymi have been described, and only one 
that I can find figured. It is most likely that the genus is 
very extensive ; but my own cabinet contains only seven 
species, all of which are females, excepting the one figured in 
our Plate.

We believe the group under investigation has been united by 
Dalman with the Pteromali, a genus of Latreille's allied to 
Perilamjms ; but Colas is nearer, perhaps closely allied to 
Cleonymus of the latter author which embraces those species 
with clouded wings, truncated antennae, the abdomens of the 
females being similarly shaped to ours, but longer ; from being 
unacquainted with their males, we cannot at present enter 
further upon the subject. From other genera of the same 
family, the one before us seems to be sufficiently distinct, and 
easily distinguished when the sexes are known. The authority 
on which we give the two insects in the plate as sexes of the 
same species, is tolerably satisfactory ; but so far from wishing 
that it should be received as conclusive, we would invite those 
who are interested in the subject to pay attention to the lepi- 
dopterous Chrysalides producing these pretty insects, which 
will enable them to supply invaluable information upon a 
family whose economy is highly interesting and but imperfectly 

In the 136th plate of this work the caterpillar of Acronycta 
Salicis is given ; and from one of these (which spun itself up 
in a web, but died before it became a pupa, in consequence of 
its being inoculated by these parasites) we obtained, the be- 
ginning of the following June, about half a dozen males and 
twice as many females; and amongst 10 or 12 more species of 
this genus, few of which appear to be described, is a pair that 
I took last September upon the Achillea Millefolium^ in the 
Isle of Wight, not differing in form but essentially in colour. 

Colas is derived from the Greek, and alludes to the parasitic 
economy of this group ; and the specific name of dispar is cha- 
racteristic of the disparity of the sexes. 

Our insects were inhabitants of the Trossacks, and specimens 
of the plant figured, Viola lutea (a variety of the yellow Moun- 
tain Pansy), were tolerably abundant on the north and east 
sides of Schichallien the beginning of July.

Mr. Haliday first proposed the genus Phagonia, which is 
recorded in my Guide ; and as its singular structure renders 
it interesting, and neither figure nor description of it having 
been published, it is hoped that the present notice will be 
acceptable to those engaged in the study of this beautiful and 
extensive family of Hymenoptera. 

Dalman in a slight Conspectus of his genus Pteromalus 
mentions 3 of his species having entirely yellow antennae with 
incrassated palpi, under the names of chilodes, patellanus, and 
■palpalis; but as no characters are given, it is impossible to say 
whether our species be the same as his. 

I am indebted to Mr. Haliday and Mr. Walker for speci- 
mens of the type, which may be thus described : 

1. P. flavicornis Hal. — Curt. Guide, Gen. 631. 1. 

Length 1 line, or a little longer : bright golden green, ex- 
cessively thickly punctured : eyes black ; palpi orange, man- 
dibles pale ochreous, tipped with black : antennae ochreous, 
black at the apex, 2nd joint brownish at the base : abdomen 
metallic, polished, 2nd joint violaceous, peduncle aeneous black 
and punctured: wings with the nervures lurid. Legs deep 
and bright ochre, coxae green, tips of tarsi brown. 

Taken in June and July by Mr. F. Walker on Ferns in 
woods at Southgate. 

The following is the description of the insect supposed by 
Mr. Walker to be the female : 

Length 1^ line. Brilliant green with a golden tinge: 
excessively thickly punctured : eyes and antennae black, the 
latter ochreous at the base : palpi' small and blackish : man- 
dibles ochreous : abdomen rhombiform, metallic, polished, 
with a violaceous tinge towards the apex: wings with the 
nervures lurid: legs ochreous, coxae green, trochanters and 
thighs, excepting the tips of the latter, black ; tarsi brown at 
their apex. 

Taken with the last.

Smiera is distinguished from Eucharis by its curved posterior 
tibiae, and from Chalcis by the length of the petiole. I sus- 
pected from the manner in which the S. sispes hovers about 
and settles upon the rushes, that the female laid her eggs in 
larvae either upon or inside the stalks, but we learn from 
Latreille that these insects " deposit their eggs in the nymphae 
of the Stratiomydte or of some other diptera, the larvae of 
which live in the water." 

I shall now describe the British species. 

1. S. sispes Zy/w«. F.S.n.l657. — chwipes Fab.— Patiz.78. 15. 

—Sam. pi. 8./. 6.— Don. 11. 379. 

Black, thickly and coarsely punctured, abdomen smooth and shining : 
wings pale fuscous : posterior coxse very long and a little stouter than the 
peduncle : 4 anterior thighs ferruginous at the apex, the intermediate pair 
incrassated at the apex, hinder pair large, lenticular and rufous, black at 
the apex, serrated beneath, the basal tooth the largest : tarsi ferruginous, 
black at the tips. 

As this is the Linnaean species, I have retained its original 
name. I am sorry to find continental naturalists superseding 
old established names, for the right of priority will always be 
respected by the true friend of science. This insect is found 
from June to the end of July on rushes at the back of the Red 
House, Battersea ; Kensington Gardens ; near Faversham, 
Kent ; on umbellate flowers, Whittlesea Mere, Mr. Dale ; 
sides of ditches, Tollsbury, Essex, J. C. 

In the two following species the antennae of the females seem 
to be only 12-jointed. 

2. S. Macleanii Curt. Brit. Ent. pi. 472 ? . 

Black, thickly and coarsely punctured, clothed with fine pale hairs ; 
antennffi clavate ; scutellura emarginate, peduncle half the length of the 
abdomen, which is smooth and shining : wings stained brown, costal 
nervures piceous ; scapulars and tips of 4 anterior thighs pale yellow, 
posterior minutely punctured, serrated beneath, with 2 larger teeth at 
the base, the external one pale yellow, as well as a sublunulate one 
towards the apex and a round one opposite on the inside ; base of anterior 
tibiae ochreous, the tips ferruginous as well as the tarsi which are brown 
at the apex. Male undiscovered. 

I have named this fine insect after Dr. Maclean, of Colches- 
ter, whose zeal for science and ardour in the pursuit of know- 
ledge have led to many discoveries that entitle him to the 
thanks of all lovers of Natural History. It appears to be very 
similar to the C. higuttata of Spinola and the C. melanaris 
Dalm., from which it is at once distinguished, by the 3rd spot 
towards the apex on the inside of the hinder thighs, as well as 
by other differences of colour. I first discovered S. Macleanii 
the end of June, settling on the rush figured, in a ditch at 
Tollsbury ; Mr. Bennet soon after took another in company 
with the S. sispes, and Dr. Maclean captured a third. 

3. S. petiolatus Curt. — sispes Fab.—Panz. 77-11. 

Black, thickly and coarsely punctured, scutellum slightly emarginate, 
petiole long, slender and yellow ; body smooth and shining ; a yellow 
spot on each side the face, scapulars of the same colour : thighs yellow, 
black at the base, posterior with a saddle-shaped black mark above at the 
base, and a brown one at the apex : tibiae yellow, 4 anterior brown at the 
middle, posterior piceous except at the tip : tarsi ochreous : antennae of 
male rather long stout and subfusiform, the basal joint the slenderest ; 
short slender and clavate, I believe, in the female. 

Said to have been captured in the neighbourhood of London. 

This being the C. sispes of Fab., who very carelessly trans- 
posed the names, it is become necessary to give the species 
another appellation to prevent further confusion. 

The Plant is Scirpus maritimus (Salt-marsh Club-grass).

In the Cabinets of Mr. Stephens and Mr. Bainbridge. 

Perilampus, a genus containing several European species, 
was separated from Cynips and established by Latreille in his 
Genera Crustaceorum. The wings of the Cijnipsidce seldom 
furnish generic characters ; and in many other tribes of Hy- 
menoptera, their structure is not available for separating small 
groups, they consequently become rather characteristic of fa- 
milies or of tribes ; and this led Jurine (whose system was built 
upon their conformation) into the error of uniting the Fabri- 
cian genera of Ichneumonidce^ and considering that vast group 
as a genus. The same system compelled him to sink many ex- 
cellent genera amongst the bees, and prevented him from admit- 
ting of any material division in the Cynipsidce or Diplolepidce. 
The antennae however, when carefully examined, will supply 
the deficiency by furnishing the best generic characters for ge- 
neral use ; for although we believe that the trophi are of the 
first importance, it is not possible for the student to examine 
those parts in every specimen ; and characters obtained from 
more convenient parts will enable him to decide upon affinities 
after a genus is firmlj^ established by dissection. At present 
we shall not enter into the merits of our genus : it may not 
be amiss, however, to remark, that the singular manner in 
which the labrum is produced into spines, and the same dispo- 
sition in the terminal joint of the maxillary palpi, have not 
been before noticed. 

The metallic hue of the bodies render the Perilampi striking 
and beautiful objects, although inferior in splendour to their 
neighbours. They are parasitic, feeding in the larva state 
upon caterpillars, and forming an oval cocoon, which Reaumur 
represents suspended from a branch by a thread. 

The species figured not agreeing with Fabricius's descrip- 
tion of Cynips t-iificornis^ which is said to have a black head 
and thorax, nor with Panzer's Chalcis molacea^ which has the 
4 anterior legs entirely ochraceous, we have considered it as 
a nondescript, and called it P. pallipes, from its pale feet. 
Mr. Bainbridge took a male at Darent; and the female figured 
was taken off an umbelliferous plant by Mr. Joseph Standish 
at Dover the end of last July. 

The pretty plant in the plate, Antirrhinum spiirmm (Round- 
leaved Fluellin), was gathered upon the heights at Dover.

Some of these Insects I breed in vast quantities from the beau- 
tiful moss-like balls attached to the branches of the Dog-rose, 
called Bedeguar, and known in some parts of England by the 

name of "Robin's Pincushions;" they are easily bred by placing 
the galls under a tumbler, and are beautiful objects for the mi- 
croscope, for in elegance of form and beauty of colouring they 
can scarcely be surpassed. These mossy excrescences are sup- 
posed to be entirely formed hy Cy^iips Rosa, and our insects 
are said to feed on their larva^, and most skilful parasites they 
must be, for in breeding them 1 have often obtained nothing 
but the Callimome, and it is very remarkable that from mul- 
titudes of the galls of the Wild Carrot I never bred any other 
insect than the C. Dauci. 

In the Stockholm Transactions for 1820, and a subsequent

Decatoma Spin., Curtis's Guide, Gen. 650. — Eurytoma Dal. 

Antennce inserted in the centre of the face, geniculate, pilose, 
excepting the basal joint, which is received into a groove in front 
of the face, longer in the male than female ; 9-jointed in the male, 
the 1st joint long, 2nd curved subpyriform, two annuli forming 
the base of the 3rd joint which is oval truncate, longer than the 
3 following which are remotely articulated, the remainder form- 
ing a narrow elongated club, the apex producing very short 
spreading bristles (i) : 10 -jointed in the female, 1st joint long, 
2nd slender, bent subpyriform, then follow I think 2 annuli, the 
3rd joint obovate truncate, 4 following semioval, the remainder 
forming an ovate or conical club (1 a). 

Mandibles subtrigonate, truncated obliquely and tridentate, the 
apical tooth acute, the internal one blunt (3). 
Maxilla: long and narrow, rounded and ciliated at the apex, and 
producing a membranous dilated margin. Palpi slender, triarti- 
culate, basal and 3rd joints long, the latter truncated obliquely 
and pilose, 2nd joint subovate (4). 

Mentum rhomboid. Lip large, oblong, narrowed at the base, the 
anterior margin sinuated. Palpi large, biarticulate, basal joint 
truncate, 2nd subovate pilose (5). 
Head broad, short, slightly concave in front. Eyes large, lateral. 
Ocelli 3. Trunk oblong : prothorax large transverse. Scutellum 
rounded. Wings remote from the head, pubescent, ?,Vi^Qx\o\- large, 
obtuse, vnth a subcostal nervure, touching the costa beyond the centre 
where it forms a short branch. Abdomen very small, subglobose and 
attached by a long stout petiolus in the male : longer ovate, slightly 
compressed, the petiolus much shorter and the apex acuminated, with 
an ovipositor beneath in the female (6 ; a, the point of attachment) . 
Coxae large, producing a transparent plate at the apex of the ante- 
rior pair : thighs incrassafed, especially the posterior : tib'ae spurred, 
posterior ciliated externally with a few spiny bristles : tarsi 5-jointed, 
basal joint the longest: claws bent: puhiWi distinct (8, afore leg). 

CooPERi Curtis. 

Female black, pubescent, very closely and coarsely punctured j 
underside of antennae, tip of the 2nd joint and the apex ochreous^ 
face of the same colour : collar with a narrow orange border, 
broadest before and interrupted behind ; base of the wings 
orange : abdomen very smooth and shining : superior wings 
with a sublunular brown stigma, black at the costa, the nervures 
ferruginous : legs ochreous, posterior coxae black, intermediate 
thighs with a streak of black, the posterior black except at the 
base and apex, posterior tibiag black in the middle. 
In the Cabinets of Mr. Cooper and the Author. 

Decatoma is a genus proposed by Spinola, but I am ignorant 
of his characters : from the typical Eurytoma it is distinguished 
by the antennae being clavate in the female ; and the 2nd basal 
joint is very nearly as long as the 3rd, not reckoning the little 
rings ; whereas in Eurytoma, the 3rd joint is frequently almost 
as long as the basal one, and very much longer than the 2nd. 
It is very important to remember, also, that the maxillary palpi 
are only triarticulate ; for Mr. Haliday has observed, that they 
are composed of 4 joints in E. longula ? Dal. 

I shall characterize the species lent to me by F. Walker, Esq. 
of Southgate, where they were taken, I believe, on grass under 

1. D. Cooperi Curtis' s Brit. Ent. pi. 34^5. fern. 

For males of this pretty insect, I am indebted to A. Cooper, 
Esq., who beat them out of a hazel-bush, with one female, in 
September, close to the river Mole at Cobham. 

2. D. biguttata Swed. — Fejnale much smaller, but similar to 

No. 1 : antennae black, the tip of the 2nd joint only 
ochreous : face variegated with yellow : collar of the 
same colour, with a large trilobed black mark : abdo- 
men with a yellow spot on each side, near the centre : 
legs pale ochre, variegated as in No. 1. 

3. D. variegata Walk. MSS.—SimWsiV to No. 2, but much 

smaller : the collar is yellow, with the centre and a 
spot on each side black, a yellow horse-shoe-formed 
mark above each upper wing : the hinder thighs have 
only a broad black ring round the middle, and the 
stigma is trigonate. 

4. D. obscura Walk. — Female similar to No. 3, but the collar 

is almost entirely black : there is no yellow spot on the 
side of the abdomen, as in No. 2 and 3 ; the hind thighs 
and tibiag are black, except the knees : stigma sublu- 
nulate, pale fuscous, black at the costa. 

5. D. unicolor Walk. — Male much smaller: antennae pale to- 

wards the apex : stigma small, black : tarsi and knees 
of hinder legs alone yellowish, the former fuscous at 
the apex. 

6. D. minuta Walk. — Male similar to No. 5, but the face is 

variegated with ochre : there is an ochreous ring ou 
each side the collar, and the tibiae are ochreous, ex- 
cepting the middle of the posterior pair, which is black. 

7. D. mellea Walk. — Male as large as No. 2, ochreous : collar 

and head yellowish, both a little blackish at the base : 
scutellum variegated with black, and three large con- 
nected black spots on the back of the abdomen. 
S. D.?penetransJv/V.— Brassy-black: abdomen bluish-black, 
compressed : apex truncated : aculeus subexserted. — 
Linn. Jrans. 5. 4./ 10, IJ. 
This minute insect is probably allied to the present group. 
Corylus Avellana (Hazel-nut Tree), in flower, accompanies 
the insect.
