(Common Separate-headed Carex). I regret that in their journey from Cam-
bridge the labels were displaced, which led to a transposition of the names.

389 Agriotypus armatus. Mr. Wailes in a letter says, " I took a specimen on the
shore of Derwentwater (amongst the small stones so characteristic of lakes
amongst the older strata,) in April last. It is a female."

395 The characters of <? and ? added to the figures of the antenna? in the Plate,
have been accidentally transposed, and the signs in the description, lines 14 and
1 7, have been made to correspond, to prevent further mistakes.

357 Anthophora Haworthana. Since this species was published I have received
a pair from Dr. Howitt, who takes the sexes near Nottingham : the female is
so similar to that of A. retusa, that the only difference I can discover is in the
colour of the spurs to the tibire, which are ferruginous, and not dusky or black
as in A. retusa.

Ohder Hymenoptera. Fam. Chrysididae.

Type of the Genus, Sphex semiaurata Linn.

Cleptes Lat., Fab., Shuck., Curt. — Ichneumon Rossi.— Sphex Linn.

Antenna inserted near the margin of the clypeus, approximating,
not so long as the thorax, geniculated, velvety, a little attenu-
ated in the male, and 13-jointed, hasal joint the longest and
stoutest, metallic and hairy, 2nd the shortest, ohovate-truncate,
3rd twice as long and linear, the following shorter, oblong,
slightly attenuated to the apical joint which is the slenderest
and elliptic-conic (1 <J) : shorter, the flagellum curved and atte-
nuated to the base and apex in the female, 2nd joint not very
short, 3rd long and narrowed at the base.
Labrum forming a small horny subovate lobe, ciliated with long
hairs (2).

Mandibles elongate-subtrigonate, tridentate on the inside to-
wards the apex, pilose externally (3).

Maxilla terminated by a large ovate ciliated lobe, with a smaller
pubescent one on the inside. Palpi not veiy long, pubescent,
5-jointed, 2 basal joints rather short, 3rd longer, very stout,
subovate, 4th not so stout, but about as long, 5th the longest,
slender and linear (4).

Mentum corset-shaped. Lip small, fleshy and concealed. Palpi
moderate, remote, pilose, triarticulate, 2 basal joints obovate,
truncated obliquely, 3rd joint much longer, subfusiform (5).
Head short, transverse, narrowed behind : eyes oval : ocelli 3, forming
a triangle on the crown of the head. Thorax obovate with longitu-
dinal sutures, and divided transversely into 4 segments : scutel semi-
ovate : metathorax subquadrate, the angles acuminated. Abdomen
ovate, depressed, not concave beneath, 5-jointed in the males, 4-jointed

margin: inferior wings with very faint nervures. Legs moderate :
thighs short, incrassated towards the base : tibiae clavate, spurred at
the apex : tarsi simple, 5-jointed, basal joint long, 4th small : claws
and pulvilli distinct (8 t)-

Nitidula Fab. — Curt. Guide, Gen. 656. 2.

From the numerous illustrations we have given of the Cyni-
pidae of Latreille, it will be remembered that they either have
no labrum, or it is so minute that it has not been discovered,
except in Perilampus and Smiera: the small labrum of
Cleptes forms a beautiful transition from the above family to
the Chrysidae through Hedychrum; and I have lately received
a most remarkable metallic Bee from America, I believe from
Columbia, which will prove, I expect, that there exists a
strong affinity between the Andrenidae and Chrysidee. La-
treille considered that Cleptes was allied to Bethylus (PI. 720),

but I must confess I cannot see any analogy, and with Tiphia
(PI. 664) it has no relationship.

The Cleptes are parasitic upon other Hymenoptera, and
St. Fargeau seems to think that C. semiaurata is the parasite
of a Tenthredo.

It is very remarkable that there does not appear to be any
very marked character to distinguish the males of the two
species, although the females are so very dissimilar: the greatest
difference seems to me to be in the colour of the 3d segment
of the abdomen, which has much more of the ochre colour in
C. semiaurata than in C. nitidula, and the tibiae I believe are
generally more ochreous.

1. semiaurata Linn. Panz. 51. 2. o*. — splendens Fab. —
auratus Panz. 52. J . ? .

Male bright metallic green, slightly villose : antennae black,
basal joint green: head and thorax coarsely punctured, faintest
on the disc of the latter: metathorax rugose : abdomen shining
deep ochre, the extremity of the 3d segment black, forming a
point in the middle : the following bright blue : wings slightly
fuscous, the stigma and nervures brown : legs fulvous, coxae
and thighs green, tarsi fuscous.

Female bright cupreous, 5 basal joints of antennae ochreous,
the remainder black : abdomen as in the male : wings fuscous,
with the base and an irregular long spot beyond the disc trans-
parent : legs entirely fulvous.

Rather larger than the following: it lives in sandy places,
and is not uncommon in the vicinity of London in June ;
Mr. Paget takes it at Yarmouth ; I used to find the females in
gooseberry bushes in a garden, and they have been detected
on the horse-bean in a field near Coventry.

2. nitidula Fab.— Curt. Brit. Ent. pi. 724- ? . — Panz. 106. 11.
Male bright metallic green, inclining more or less to blue

or purple: antennae black, basal joint green, head and thorax
not thickly punctured ; metathorax deeply and closely punc-
tured : abdomen shining deep ochreous, the 3d segment, ex-
cepting the base and the following, bright blue, green, or
purple, the apex punctured, wings slightly fuscous with a
cloud on the disc, the nervures and stigma piceous: legs
bright green : tibia? ochreous, the four posterior often piceous,
excepting the tips : tarsi fuscous.

Female. Head and thorax cupreous : prothorax ferru-
ginous-ochre, metathorax bright green : antennae black, 2d
and 3d joints ochreous : abdomen as in the male : wings with
a slight cloud at the stigma: legs ochreous, hinder thighs and
coxae piceous, tarsi fuscous at the apex.

Taken by Mr. Paget on the sand hills near Yarmouth in
June : Mr. Rudd finds it plentiful in Yorkshire, and it occurs
also in the New Forest.

Trinia glaberrima (Pimpinella dioica), Dwarf Burnet Saxi-
frage, from St. Vincent's Rocks, was communicated by G.H.K.
Thwaites, Esq.

In the Cabinets of the British Museum and the Author.

In a former number (folio 8.) was given the Genus Chrysis t
and another group of the same family, separated by Latreille,
is the subject of the present paper. Although the Hcdychri
may equal the Chrysidcc in splendour, their form is by no means
so elegant; the ODtuseness and breadth of the abdomen di-

stinguisliing them at first sight; and upon further comparison,
the absence of the transverse line of impressed dots upon the
last joint of the abdomen, as well as the great difference in
the mandibles, independently of the variation in the wings,
excite our astonishment that Jurine should have rejected a
Genus so natural and well established.

Dr. Leach has divided this Genus into those with the apex
of the abdomen entire, 1. H. punctatum Leach?; 2. lucidulum
Geoff.; 3. ardens Lat. The others notched at the apex,
4. regium Geoff. ; 5. violaceum Rossi. There are also in the
Museum cabinet a species called cceruleum and another un-
named. Our insect, which was taken several years back in
Norfolk, agrees tolerably well with Latreille's description, and
perfectly with the British specimens in the Museum, but not
very well with the rude and careless figure in Coquebert.
Some specimens are twice the size indicated in the plate by
the crossed lines.

The habits of this Genus are somewhat dissimilar to those
of the Chrysidee, being generally found in the sunshine upon
the leaves of brambles and other bushes, from which they fall
upon being approached, rolling themselves up into a ball.

The plant figured is Antirrhinum Cymbalaria (Ivy-leaved
Snapdragon).

In the Cabinet of Mr. Stephens.

Jurine has very aptly called the Chrysididae the Humming-
birds of entomologists ; for it must be confessed that nature
has been lavish in adorning them with the most splendid and
effulgent colours, which cannot fail to call forth our greatest

wonder and admiration. Every one who has taken delight
in observing the works of Nature must have noticed the re-
splendent hues of the common C. ignita, which is seen in the
heat of the day running up and down the southern sides of walls,
and about paling and posts in gardens where other species may
also be found. About 1 6 species have been taken in this island ;
some of them however are so closely allied, that on further
investigation they may prove to be only varieties.

The beautiful species represented is a female (the natural
size of which is denoted by crossed lines) : it was taken with
other specimens in June at Birch-wood or Bexley in Kent, by
a collector* who has for many years enriched the first cabi-
nets in the country by his labours ; and as I well recollect the
advantage and delight with which I used to visit this respec-
table man upon my earliest acquaintance with London, I have
pleasure in making mention of him here.

Latreille has very judiciously divided the Chrysididae into
seven Genera, five of which are British: Jurine, having founded
his Characters upon the forms of the cells of the wings, has
not adopted them.

The Genus Chrysis may be divided into the species with
the anal joint dentated, and those with an entire margin, as in
C. rufa Pz.

The plant represented is TJdaspi Bursa-pastoris (Shepherd's
Purse).

The history of the industrious and provident ant has been
familiar to every one from the earliest ages, and the more re-
cent researches of Huber on this subject are highly interest-
ing. I am sorry that a summary of their ceconomy is the ut-
most that my space will afford, but the amusing account given
by Kirby and Spence will supply the deficiency.

Each species of ant comprises three different sorts, namely,
the males, females, and neuters: there are sometimes two va-
rieties of these last, varying in size : they form nests in the
earth or under stones, and their sagacity, their unceasing in-
dustry, their perseverance in overcoming difficulties, and the
care they evince for their progeny, are wonderful, and well
deserving the attention of man.

The female ant lays from 4000 to 5000 eggs ; those of the
neuters are the smallest; they produce maggots that live a
twelvemonth or upwards ; these become pupae, in which state
the males and neuters remain 4 and the females 6 weeks ; they
are inclosed in oval whitish cocoons, which are erroneously
called ants' eggs, and it is these we see them carrying off to
a place of security when they are disturbed; the ants also
bring them to the surface for warmth, or heap them up in the
nests. The males and females are generally few in number
compared to the workers, yet they are occasionally found in
myriads ; the latter are often deprived of their wings, being
pulled off either by themselves or by the neuters, in order that
they may not depart from the nest, and they then work like
neuters. Gould says this does not happen till they become
mothers. Ants are chiefly nourished by the saccharine fluid
from Aphides (pi. 576 and 577), and they remain in their
nests through the winter in a torpid state. The males and
females swarm from Midsummer to Michaelmas, and the neu-
ters bite with their serrated jaws, but none of the British species
sting. Of these, eleven have been recorded in the Guide,
but I have only seen indigenous examples of 5 of them. The
species figured forms a large nest of straws, sticks, leaves, and
other convenient materials : they are very partial to oak-woods
and fir-groves, the leaves of the coniferae supplying them with
admirable and very portable building materials : they seem to
be at work day and night from March to the end of October :
the males and females are commonly found in June and July.

The only specimens I have ever seen of this little insect were
all males, which I swept off rushes the middle of August and
beginning of September, at the back of the Isle of Wight,
where they were flying about ; and having been unsuccessful
in searching for the females and neuters, I am induced to
publish the materials I possess, hoping that it may lead to the
discovery of the sexes.

Myrmecina is nearly related to Myrmica, of which genus I
would willingly have made it a division; but the short basal
joint of the antennae, the different nervation of the wings, and
above all, the absence of the mandibles, rendered this desirable
object impracticable. The labrum also is remarkable for hav-
ing the basal angles thickened and produced ; and these I am
almost disposed to think are modifications of mandibles.

This nondescript insect I have the pleasure of dedicating
to my esteemed friend Mons. Latreille, whose investigation of
the family to which it belongs, as well as his numerous valu-
able works on Entomology, have contributed so effectively to
the philosophical advancement of Science.

Tbfi beautiful plant represented is Lathyrus sylvestris (Wild
Lathyrus), it grows luxuriantly on the sloping cliff between
Bonchurch and Luccomb Chine, and spontaneously orna-
ments the elegant grounds of James Vine, Esq. at Puckaster
Cove in the Isle of Wight.

Although the Mutilladce bear considerable resemblance to
the Formicadce their economy is totally different, the latter
living in societies exhibiting males, females, and neuters, which
last only are apterous ; the former being solitary, having no
neuters, the males only being furnished with wings. It is un-
necessary to go any further into the differences of the two
families. The female Mutillce want the little eyes upon the
crown of the head, as well as the wings with which the males
are furnished; and the eyes and thorax are very differently
formed. Jurine has justly observed " What is the object of
Nature in establishing such disparities, and where is the utility
of it ? These are problems that we cannot resolve, because of
our ignorance of the history of these insects, but which well
deserve the attention of naturalists." It is well known that they
inhabit sandy districts, and it is probable the females form
their nests and deposit their eggs in such situations, which
employment would render wings and ocelli of little use; whereas
the males, which may be less numerous than the other sex,
are supplied with wings to enable them to go in search of the
females, as is frequently the case amongst the Lepidoptera
and other orders.

We are able to record at present only three species of this
beautiful genus as inhabitants of Britain : 1 . M. Europcea Linn. ;
2. calva Fab.; 3. EpJiippium Fab. The first is common in
sandy lanes and foot-paths in June, — it is figured in Donovan's
Brit. Ins. v. 6. p. 212.; the second, (in the cabinet of Mr.
Stephens,) is figured in Coquebert's Icon. Ins. tab. 16. f. 10.
Latreille and many other entomologists have long suspected
M. Ephippium and M. rufipes to be the sexes of the same
species, since we only know the males of the one, and the
females of the other : as such I have ventured to give them,
having found both insects in this country, — the female in a
gravel-pit, and the male flying over a sunny bank near
Shooter's-bill, Kent, the 15th June 1822.

Bryum subulatum (Awl-shaped Screw-moss) is figured in

The only British insects with which Methoca might be con-
founded are the females of Mutilla and Myrmosa, and the
apterous Ichneumonidae (Pezomachus Grav.); the peculiar
form of the thorax will however at once distinguish our insect
from the rest ; and it is further separated from the females of
the first by the ocelli, and from the Pezomachi by the fewer
joints of the antennae, independent of the 6-jointed maxillary
palpi and other differences in the trophi.

The specimen from which the drawing was made is, I be-
lieve, the only British one discovered, and has never been re-
corded as a native of this country, excepting in the Guide. I
took it the 30th July 1828, running upon a mass of sand-stone
ascending Black-gang Chine in the Isle of Wight. I looked
in vain for another, and was not more successful in my search
for the Tengyra Sanvitali. It is to the liberality of a most
zealous and distinguished entomologist at Lyons, Mons. Fou-
dras, that I am indebted for a specimen of this insect to dis-
sect, as well as for the Tengyra and other rarities.

Latreille says that the Methoca is found running upon the
ground in fields in the South of France, but very rarely :
Mons. Foudras has taken it near Lyons with Tengyra Sanvi-
tali, which he believes to be the male, and the same opinion
having been entertained I believe in the 7th vol. of the Annales
du Musee,! shall subjoin the characters, partly from Latreille' s
Gen. Crust, v. 4. p. 116, with additions from my own observa-
tion.

The Scoliidae form a very extensive family inhabiting warm
latitudes and the tropics. On the sandy shores of the Medi-
terranean, especially near Frejus, I found a considerable num-
ber of species, but none inhabit Great Britain or the North of
Europe that I am aware of, excepting the genus Tiphia, for
Sapyg<*i pl. 532, is evidently a distinct family, and Tcngyra

being the male of Methoca, pi. 329, must be united to thc-
Mutillidae.

The male Tiphiae are often found resting on the ground,
especially in sandy districts, and the females frequent umbel-
liferous and other flowers. The difference in the marginal
cell, which is closed in the male, as shown in our coloured
figure, and open in the female, as represented at fig. 9, forms
a remarkable character in this group.

1. femorata Fab. — Panz. 53. 3. — Jur.pl. 9. Gen. 11. — villosa

Black, shining, pubescent, metathorax with 3 elevated lines,
the central one abbreviated, legs rufous in the female, anterior
pair brown; wings pale reddish-brown : length 2^ to 5 lines.
Latreille says this insect makes its nest in the earth at the
end of summer. It is a common and variable species ; some*
times the legs are red in the male and black in the female.

Taken in Norfolk, Birch Wood, the New Forest ; August,
Parley and Charmouth, Mr. Dale ; on the beach at Bourne-
mouth, the Honourable C. A. Harris ; and on flowers near
Dover in July, J. C.

elevated lines ; the wings with their stigma very large, and
their nervures piceous. The abdomen very villose and
shining : length 5 lines." Shuck.

The male in the British Museum is believed to have been
taken in Devonshire by Dr. Leach. The Fabrician specimen
was from Spain.

3. minuta Vand. Lind. — Curt. Brit. Ent. pi. 664<. S •

Male. Intense black ; shining and pubescent ; palpi brown,
apex of mandibles ferruginous ; metathorax with 3 complete
elevated lines ; abdomen very finely punctured : wings
stained brown; nervures deeper, stigma large ovate and

ochreous, tips of the other tibiae and all the tarsi sometimes
ferruginous ; spurs whitish : antennae reddish brown be-
neath in the female, mandibles rufous only at the middle ;
apex of abdomen pitchy-red.

The neuration of the wings varies greatly in this little spe-
cies, as shown by Mr. Shuckard, who has taken several speci-
mens on Hampstead Heath, and Mr. Dale finds it in abun-
dance atGlanville'sWootton on grass and laurels, from the end
of March to June. He informs me that he took a 4th species
on the sand-hills at Braunton Burrows in Devon the end of
July. I observed the male of T. femorata in considerable
numbers on the sand-hills at Boulogne the end of August, but
not one female !

Sapyga is a remarkable Insect; its ample collar reminds us
of the Chrysidac, but in general aspect as well as in the shape
of the palpi and the form of the maxillary lobe, rounded and
reflected, we cannot fail from drawing a comparison with Hy-
lieus (pi. 373) and the Andrenidae : it appears, however, to be
most related to the Mutillidas and ScoHidse, and like them
the females have the power of stinging very acutely.

Dr. Klug says these Insects frequent flowers in meadows

and fields and fly swiftly : there are only 2 species inhabitants
of England, although from the sexes being so very dissimilar
in one, and the body of the male varying greatly in the num-
ber of the spots, they have been described by Fabricius and
others under a variety of names, as

too many joints in the antennae.
Male black ; antennae with a few of the central joints fer-
ruginous beneath ; clypeus and a stripe on the anterior tibiae
white; 3rd and 4th, and sometimes the 2nd and 5th segments
of the abdomen with a white spot on each side, with similar
spots occasionally on the underside. Female often having 3
white dots on the head, and one on each shoulder, 2nd and
3rd segments of abdomen rufous, 4th and 5th with a white
spot on each side, 6th with one at the apex.

I never saw so many of this insect as on the 11th of June,
at Ambleside, in company with Mr. Dale, when the females
were flying about the stone walls in plenty; but the males were
comparatively rare, and were settling on the ground at the
base of the walls : I have found this sex also at the back of
the Isle of Wight ; Mr. Donovan took it at Faversham in
Kent; Mr. Walker at Southgate in July; and Capt. Blomer
in the New-forest.

joints, ochreous; clypeus, a dot on each shoulder, a dot at the
apex, 2 spots on the 2nd segment and an interrupted band

terior, and a spot at the base of the other tibiae of the same
colour. Female with the clypeus black, 2 yellow dots between
the antennae, which are clavate only, and the apical joint alone
ferruginous beneath and at the tip : wings dusky ; abdomen
similar to the male, but with 4 yellow spots beneath.

I am happy in being able to restore Linnaeus's name to this
species, the specimen contained in his cabinet being a male,
with a label of his own writing.

Females were observed bv Mr. G. Newman in the autumn,
in considerable numbers, settling on the leaves of a Morella
cherry-tree in a garden near Leominster, and also by Dr.
Howitt near Nottingham : for the loan of the male I am in-
debted to Mr. Shuckard, who has also obligingly added the
other sex to my Cabinet.

The Plant is Hicracium Pilosclla (Mouse-ear Hawk-weed).

The Pompili inhabit sandy situations exposed to the sun ;
and we learn from Latreille that they bury a spider or cater-
pillar in a cell formed in such places, and close the aperture,
having previously laid an egg, which is nourished when
hatched by the insect inclosed with it.

The Pompili (as the same author observes) are very active,
they are continually flying from one place to another ; they
run also very rapidly, and often vibrate their wings and an-
tennae. The reader will be amused by referring to Kirby and
Spence, vol. i. p. 339 or 344?.

In the Cabinets of the British Museum and Mr. Rudd.

The females of this genus are readily distinguished from those
of Pompilus (pi. 238) by their antennae, which are not convo-
luted, but simply curved like those of the male; the anterior
feet are also simple, and not ciliated with long spiny bristles,
and the ovipositor is a little exserted ; the males are less easily
separated, but on an examination of the trophi, very decided
differences will be found in the labrum and mandibles.

The Ceropales are supposed to be parasitic, depositing
their eggs in the larvae of other fossorial Hymenoptera.

1. maculata Fab. — frontalis Panz. 72. 9. ? .

in the female cream-colour : a band on the collar and a
spot on the scutel of the same colour: 1st abdominal seg-
ment with 2 cream-coloured spots, margin of the 2nd and
apex white : legs ferruginous ; coxae, hinder thighs and apex
of tibiae and tarsi more or less brown.

Campestris Lat. — pubescens Curt. Guide, Gen. 672. 5.

Natural as this group is, there are many variations in the
structure of the species: the trophi are less elongated in the
temale of A. hirsuta than in A. sabittosa, and the mandibles are

obtuse : the petiole of the abdomen varies considerably in
length and form, even in the sexes, and in one species the 3rd
submarginal cell is pedicled : this forms a portion of Jurine's
Miscus, but I cannot think it advisable to establish this genus
on such slender grounds.

The ceconomy of these insects is very remarkable, and al-
though well known I shall add a few lines from my own ob-
servations. On the 26th of August I saw a female A. sabu-
losa ascend a sandy bank, dragging a caterpillar, which it car-
ried beneath it as the trunk of a tree is suspended under a Gill,
holding it near the head with its jaws : having arrived at the
desired spot it left the caterpillar, and proceeded about an
inch to a place covered with sand, which it scratched away, and
then with astonishing dexterity removed, and with its jaws
drew out of a hole, comparatively large pieces of earth that
closed and concealed the orifice ; some of these were so far in
that it had to go beyond its own length, of course backing out
every time: having completed this operation, it seized the larva
and went backward into the hole, drawing the caterpillar quite
down; after a short time the fly came out, and being frightened,
it flew away. On the following day the Hon. C. Harris and
myself saw another larva entombed ; it was a Geometra \ \ inch
long ; that yesterday was a Noctua, probably meticulosa: having
buried it the fly remained in the cell. We then dug out the
caterpillar, and found a cylindrical white egg ^th of an inch
long, attached firmly to the middle; the Ammophila was below
and came out much alarmed.

Mr. Kirby was acquainted with the male of one species only

when he characterized this genus, and my ignorance of that

sex led me into several errors in the Guide.

I. Petiole of abdomen elongated and formed gradually :
a. 3rd submarginal cell pedicled.

1. campestris Lat. — Curt. Brit.Ent.pl. 604?.

Dead black, clotbed with short grey pubescence, giving the apex of the
metathorax and the outside of the hinder coxae a silvery appearance :
sparingly punctured : metathorax very finely striated transversely, 2nd
joint of abdomen, excepting tbe base, 3rd joint and base of the 4th orange ;
costa, disc of cells and the fimbria yellowish-fuscous, scapulars, stigma and
nervures brown. The male has a silvery face, the entire upper side of tbe
2nd joint of the petiole and a long ovate spot on the back of the 3rd seg-
ment black.

I discovered the female in Norfolk 20 years since, and the
male I took at Ramsdown, near Heron Court, the end of Aug.
b. 3rd submarginal cell simple.

A solitary example in the British Museum, and another in
Mr. Donovan's collection, were the only specimens preserved
of this insect, and nothing was known of its habits or locality ;
I was therefore highly gratified last summer, by capturing
several of both sexes ; they are exceedingly active ; and La-
treille says they are called Astatae, because they are always in
motion.

On a fine day, the end of last July, whilst rambling about
the undercliff at the back of the Isle of Wight, I observed
two males on a pathway leading through heath and rushes ;
a few days after, I found two more males on sandy spots near
the same place; and on the 12th of August, a young friend
who was my companion, took a female at the top of the cliff';
and towards the latter end of the same month, on a gravelly
walk at Ramsdown, surrounded by heath, rhododendrons
and pine-trees, I took four females, each of them carrying a
pupa of Pentatoma prashia, Linn. ; or of P. dissimilis, Fab. :
and as nothing was known of their ceconomy, it was an interest-
ing and remarkable fact ; and there is scarcely a doubt but
these pupee were to be buried by the Astata to deposit her
eggs in. The Honourable Chai'les Harris also took one or
two, which I believe were females also.

The trophi are remarkable, especially the 2nd joint of the la-
bial palpi ; and the upper lip with its long spines, some of them
furcate. Latreille says the labium is trilobed; and as his ac-
curacy is beyond all praise, I suspect that it is different in the
males, mine being a female, which was bilobed. The ante-
rior tarsi of the females are furnished with the same sort of
appendages as the Pompili, perhaps to secm-e their prey, or
to assist them in clearing away the sand in burrowing.

Panzer says his T. ubdominalis has whitish tarsi, and his
figure is so represented; and his D. stigma has the anterior
tibias annulated with white. I have therefore been compelled
to give my insect a new name ; for Mr. Donovan (who has
figured the male, which is the reason that the female is now
given) has called his the Larra pompiliformis of Panzer, which
is not of the same genus. The D. oculata of Jurine is also
perfectly distinct.

The plant is Trifolium (Melilotus) officinale (Melilot Trefoil).

In the Cabinets of the British Museum and Mr. Matthews.

Latreille distinguishes Oxybelus from Astata (pi. 261) and
Nysson by a difference in die number of die cubital or sub-
marginal cells, and the remarkable trimucronated sculellum is
a striking character.

The males are smaller than the females, their bodies are
narrower, the antennae have a greater number of joints, and
the clypeus, at least in the Type, has a projecting ridge, like
a nose. Of their ceconomy I am ignorant, but Latreille says
they bury dead flies and lay their eggs close by them.

The following species have been detected in Britain.

1 . O. uniglumis Linn. F. S. 1681. — Panz. 64. 14 ? — 10-macu-

latus Don. 11. 376. 1. 1. var.

Trypoxylon is considered to be allied on the one hand to
Tachybuliis, and on the other to Nitela, both of them Euro-
pean types, but not inhabitants of this country.

1. Figulus Linn. — Panz. 80. 16. — Jurine pi. 9. Gen. 8.
Black, shining, crypeus and the margins of the segments sil-
very on the sides.

Authors do not seem to agree respecting the oeconomy of
this abundant species, which is found on old posts, paling,
outhouses, gates, barn and stable doors, from the middle of
May to the beginning of August, and in the Isle of Wight I
have frequently found it upon rushes. Latreille says that it
avails itself of the holes made by other insects in wood to form
its own nest. As soon as the proprietor of the hole leaves it,
the Trypoxylon takes possession of it, cleans, enlarges, and
clothes the inside with a coat of diluted earth, places a spider
(Mr. Westwood says the young of Epeira diadema) in it, de-
posits an egg, and then closes the aperture with moist earth ;
each cell occupies it two days. The larva is an apode and
resembles those of bees : after having consumed its provision
it spins a very thin cocoon, in which it becomes a pupa. This
view has been confirmed by the observations of Mr. Shuckard
and Mr. Westwood, but from the account of the oeconomy of
this insect by the latter gentleman in the Trans, of the Ent.
Soc. he seems to be disposed to think that the Ttypoxylon
forms its own burrows. M. St. Fargeau considers that these
insects are parasitic, and from an anecdote published in Mr.
Shuckard's fossorial Hymenoptera it appears that Mr. John-
son detected them carrying masses composed of Aphides into
the burrows occupied by Odyneri.

Mr. Shuckard thinks this species, which is in the British
Museum, may not be an European insect.

3. clavigerum St. Farg. — Curt. Brit. Ent. pi. 652. ? .
Black, minutely punctured, clothed with short soft white
pubescence, clypeus silvery in both sexes: metathorax
striated obliquely, with a large channel down the centre :
abdomen piceous, basal joint elongated, subpyriform, with
a sharp groove down the base, the segments constricted at
the base, sides of the margins silky- white : scapulas and tips
of thighs ochreous, 4? anterior tibia? and tarsi ochreous, the
former fuscous outside, except at the base and apex. In the
male the legs are darker.

Mr. Shuckard obliged me by the loan of this insect, which
he has taken at Hampstead and Darent ; it has also been
found at Camberwell : he adds that it frequents holes in posts
and paling, especially where Heriades Campanularum (fol. 504)
nidificates.

For specimens of Polygonum viviparum, Alpine Bistort, I
am indebted to T. Howson, Esq., who took me to their locality
in the neighbourhood of Giggleswick.

Crabro is a group of fossorial insects varying so much in
structure, that MM. St. Fargeau and Brulle have formed
them into 1 1 genera, the English types of which I shall subjoin,
referring to the 3rd vol. of the Ann. de la Soc. Ent. for their
characters. Mr. Shuckard has given a very able synoptic
table, as well as elaborate descriptions of the species, a list of
which will be found in the Guide. I wish to observe that the
pellucid spots on the spoon of the masculine fore-legs are co-
vered with a membrane, and it will be seen by the dissections
of the trophi that there are ample grounds for establishing the
genus Rhopalum. These insects are often found upon um-
bellate, and some of them undergo their metamorphoses in
decayed trees. Latreille says that C. cribrarius provides for
its larvae with a Pyralis (Tortrix) that lives upon the oak :
other females nourish them with Diptera.

That the neuration of the wings is often a valuable and useful
character to assist in the formation of genera cannot be denied,
but it is equally true that a strict adherence to it without an

examination of the trophi, will frequently lead to error. The
group before us was many years since noticed by Mr. Kirby
and called Rhopalum, and other celebrated writers have con-
sidered it a distinct type from Crabro, with which Mr. Shuck-
ard has united it in his elegant Monograph of the Fossorial
Hymenoptera. On a comparison of the trophi however the
necessity of separating our two insects from Crabro is manifest :
the most obvious differences are the palpi being only 5 and 3-
jointed, whilst in Crabro patellatus the maxillary have 6 and
the labial 4 joints, and the lip is nearly as long as the labial
palpi : I ought to remark that I could not obtain recent spe-
cimens for dissection, but I have no reason to think they had
been mutilated. Even the two species of Hhopalum vary so
materially that they must form at least 2 sections ; the antennae
of the males and the clypeus are very different, as well as the
structure of the tarsi, and the remarkable lobes attached to the
abdomen I have not yet discovered in E. rujiventre.

The additional discoidal cell will distinguish Diodontus from
Stigmus ; and the more narrowed central submarginal one, as
well as the short petiole, at once separate it from Pemphre-
don. I should not, however, have detached it from the latter
genus if the trophi had been at all similar; but Pemphredon
has an undivided labrum, the mandibles are trifid, and ihepalpi
differently formed to those of Diodontus.

One British species only has been recorded, to which I
have the pleasure of adding three others.

1. D. gracilis Curt. Brit. Ent.pl. 49G.J1.

I took two males at Glanville's Wootton the middle of June,
and should have given them as that sex of the following species
if the insect supposed by Vander Linden and his friend M. Wes-
mael to be the male, did not so materially differ from my spe-
cimens.

la. D. insignis Vand. L. — Curt.

Female 2f lines ; black, basal joint of antennae beneath, a broad
stripe outside the mandibles and a spot on each side below the wings,
whitish ochre ; metathorax not strongly reticulated, striated at the
base and on a cordate space : wings slightly tinged with brown : legs
similar to jD. gracilis ; but the anterior tibise are entirely ochreous,
and the posterior are not bristly outside.

2. D. minutus Fab. Ent. Syst. 2. 302. 32.

Male 2 lines ; black, minutely punctured, lower part of face silvery ;
palpi, underside of antennae (except at the base) and mandibles, pale
yellowish, excepting the tips which are ferruginous ; scapulars and a
spot below them yellowish white, the former with a brown spot;
metathorax strongly reticulated, striated at the base ; tips of thighs
ochreous, tibiae and tarsi of the same colour, the posterior tibiae
brownish at the middle and the tips of the tarsi rather dark : wings
transparent. Female 2-§- lines ; black, mandibles as in the male, palpi
brown ; thorax the same ; abdomen stouter, ovate-conic, clothed with
very short ochreous pubescence ; tibise, tarsi and tips of thighs ferru-
ginous-ochre with a piceous space on all the tibiae at the middle, the
posterior having a few short spiny bristles outside : wings stained
pale brown, the 2nd submarginal cell trapezate.
The 1st submarginal cell is shorter in this species than in
Z). insignis, and the 2nd recurrent nervure is not united at the
middle of the posterior discoidal one, but beyond it. — July 30th,
Black Gang Chine, Isle of Wight.

3. D. pallipes Panz. 52. 22. — tristis Vand. L. p. 76. 1.

Female 2 to 2^- lines, black, shining, minutely and sparingly punc-
tured, tips of mandibles castaneous, palpi brownish : metathorax
strongly reticulated ; wings with a brownish cloud across the middle,
the 2nd submarginal cell very much narrowed above ; tarsi brown,
palest at the base, anterior tibiae sometimes of the same colour inside
towards the apex.
Pallipes is not a well chosen name for this insect : never-
theless it ought to be retained.

My specimens are, I believe, from Norfolk. The male I
have never seen.

The Plant is Hypericum pulchrum (Upright St. John's Wort).

It would not be easy to find two groups so nearly allied,
that differ more essentially in the structure of their tropin,
than Pemphredon and the species I have separated at folio
496 under the name of Diodontus, from the bidentate labrum
of the type, which, it must be remembered, is the P. iristis of
Vander Linden, and is presumed to be synonymous with
Panzer's Psen pallipcs. I), minutus is also a typical species,
but for want of specimens for dissection I could not at the

time ascertain whether D. gracilis and insignis had bidentate
labrums.

I am happy in being able to introduce some interesting re-
marks connected with the ceconomy of these insects which are
new to me. Towards the end of August, during the late meet-
ing at Bristol, Mr. Hewitson gave me some straws taken from
the thatch of a summer-house, each of them containing from
10 to 20 Hymenoptera ; a few days after, Mr. Waring took me
to the summer-house in his garden, when I saw multitudes of
small black Hymenoptera entering the straws of the thatch,
many of them carrying an Aphis. I secured some for subse-
quent examination, when I was greatly surprised to find what
I had supposed, whilst they were flying, to be merely the
sexes of one species, comprised, I believe, four genera, viz.
Hylceus annularis (folio 373), males of Psen ater (fol. 25),
Pemphredon uniiolor^ and a Diodontus. On splitting the
straws I found numbers of perfect insects, together with larvae
inclosed apparently in pollen, masses of an Aphis, and occa-
sionally a specimen of Hedychrum imperiale (fol.* 38). I had
no opportunity of revisiting the spot after I found there
were several genera whose habits were so similar; I therefore
have some doubt whether I did not take the Hylceus and Dio-
dontus out of the straws. I am pretty certain it was the Pem-
phredons that were carrying the Aphides, which I believe were
taken from a rose-bush. The Hedychrum was in all proba-
bility a parasite of the Hylaeus. The British Pemphredons
may be thus divided.

Sabulosus Fab. — Curt. Guide, Gen. 687. 1.

The Mellini are partial to dry sandy banks, where the females
form burrows to deposit their eggs; and when they hatch,
the parent carries the young larvae dead flies to feed upon.
I have twice watched the M. arvensis thus employed, and the
following observations are copied from my note-book.

Sept. 16th. I was exceedingly amused at the strength and
sagacity exhibited by a species of Mellinus. It had captured
a large blue fly, probably Musca vomitoria, which it held tight
by the rostrum with its mandibles, the under side of the abdo-

men lying parallel to its own ; in this way it flew about a
northern bank, alighting occasionally upon the grass that
covered it, when at last it found its retreat, at the mouth of
which it stopped, and entering it backward, drew in the victim
in spite of its struggling, with the greatest facility.
The following species are recorded as British.

1. sabulosus Fab. ? . — ruficornis Panz. 77. 17. 9 . — petiolatus
Panz. 46. 12. ? var.

Expanse 9 lines. Black, antennae and legs ferruginous, 2 basal joints of
the former black above ; base of thighs, excepting hinder pair, black ; in-
ternal margin of eyes and 4 dots on the clypeus ferruginous; an inter-
rupted line on the collar, a spot on the scutel, one under each wing, 4 on
the body and a band near the apex, yellow.

I took a female of this, and a male of the following, several
years since in Suffolk ; and Capt. Blomer met with it, I believe,
in the Isle of Man.

2. fulvicornis Fab. — Curt. B. E. 580. S — Panz. 98. 18. J. —
frontalis Panz. 46. 1 1. cT? I consider these to be the males of
the foregoing species, for the specimen I have figured agrees
with Fabricius's description, although Panzer's plate does
not, but this figure is evidently inaccurate, the antennae hav-
ing J 8 joints.

Black, shining, minutely and thickly punctured, hoary-pubescent; an-
tennae and legs ferruginous, basal joint of the former black above, yellow
beneath, 2nd black, a few of the following dusky above, thighs black at the
base, inner margin of eyes and clypeus, a spot at the base of the mandibles,
an interrupted line on the collar, a spot on the scutel, one beneath each
wing, 2 on the 3rd segment of the abdomen and a band at the base of the
6th, yellow ; tips of the 4 anterior thighs beneath of the same colour, and
there is a minute spot on each side the 2nd joint.

3. arvensis Linn. — clavata DeG. — U-flavum Panz. 1 7. 20. ?. —
bipunctatus Fab. var.

Male 6J to 9 lines expanse. Black, antennas rufous beneath, basal joint
yellow ; palpi, margins of eyes and clypeus and outside of mandibles yel-
low ; a line on the collar, a spot on the scutel, 2 beneath each wing, a spot
on each side the 2nd and 4th abdominal segments, a band on the 3rd and
a narrow one on the 6th, yellow : legs ferruginous, yellow inside, base of
thighs and a stripe on the inside of the 4 anterior tibiae black. Obs. some-
times the coxae and 3rd segment of the abdomen are spotted with yellow
beneath, and the 2 yellow basal spots above are wanting. Female 1 2 lines :
similar to the male, excepting the abdomen ; on the nodule of the peduncle
are 3 yellow dots, the 2nd, 3rd, and 5th segments are yellow, edges of the 2
former black, and there is alarge yellow spot on each side the 4th. Obs. some-
times there are only 2 dots on the peduncle or none, and occasionally the 3
spots on the 4th segment form a band ; in others the face, except the inner
margin of the eyes, and the antenna?, except the basal joint, are black.
The females are common on all sandy banks in August and
September, and the males on the Fern.

4. pratensis Jurine, pi. 10. G. 19. $ .

Length 7 lines. Black, inner margin of eyes and clypeus, basal joint
of antenna?, base of mandibles, a line on the collar, a spot on the scutel,
2nd and 3rd segments of abdomen, and a band at the base of the 5th ? yel-
low, coxae trochanters and base of anterior thighs black.

I have never seen a British specimen.

The Plant is Selinum palustre (Marsh Milk- weed).

Kennedii Curt. Guide, Gen. 688. 1.

In the Author's Cabinet.

The ccconomy of this genus is, I believe, unknown ; the males
bear a little resemblance, I think, to the Mutillidse, and the fe-

males have the habit of the Pompili, but the neuration of the
wings is like that of Nysson : there is, however, a combination
of characters which renders this a strongly marked genus ; the
narrow collar, the striated postscutel more or less spined, and
bearing an escutcheon-shaped impression, and the large apical
joint of the anterior tarsi characterize the females, whilst the
males are distinguished by two small remote spines at the apex
of the abdomen, and both sexes have a strong tooth at the
apex of the posterior thighs, which, although distinct enough,
is not readily seen except in profile.

The only British specimen I have seen of this genus is the
one figured, but I have heard of Mr. Kirby having another,
and on the authority of the " Systematic Catalogue," the sexes
of A. bimaculata were recorded in the Guide. As I have Ger-
man specimens, I shall add the characters of the latter that it
may be the more readily identified.

1. A. Kennedii Curt. Brit. Ent. pi. 584.

Female black, very thickly and finely punctured, and clothed
with very short ochreous pubescence ; anterior margin of the
clypeus and trophi ochreous and ferruginous, tips of mandibles
piceous ; antennas dark fuscous, underside of basal joint fer-
ruginous, postscutellum bearing an elongated escutcheon, the
sides obliquely furrowed; two basal segments of abdomen and
a small portion of the base of the 3rd rufous, with the edge of
the 2nd silky white on the sides ; wings iridescent, yellowish,
nervures and marginal ceil brown, as well as 2 spots beneath,
forming an interrupted fascia : legs pitchy, anterior tarsi tibiae
and tips of thighs ferruginous, the tarsi and apex of hinder
tibiae brown.

I have the gratification of naming this unique insect after
my friend Benjamin Kennedy, Esq., of Clapton, who was with
me when I beat it out of an Oak growing in a hedge near
Hastings, in August 1823.

So much confusion has been created by the misapplication of
synonyms that I shall not attempt to unravel them, which is
the less necessary as Mr. Shuckard will fully investigate them
in his Monograph on the Fossorial Insects. In the mean
while the reader may consult Vander Linden's Observ. sur les
Hymen, d' Europe and an excellent paper of Le Pelt. St. Far-
geau's in the 1st vol. of the Ann. de la Soc. Ent. de France.

Gorytes is distinguished by the 2nd submarginal cell re-
ceiving 2 recurrent nervures, and the following divisions form
as many genera in the Count's paper.

Gorytes. Anterior tarsi simple in both sexes.

1. mystaceus Linn. — Panz. 53. 11 ? . — campestris Linn. var.

I have found both sexes on young oaks the beginning of
June in Coomb-wood; it is abundant at Hampstead and High-
gate and at Glanville's Wootton, Mr. Dale.

In the Cabinets of Mr. Haworth and the Author.

This pretty little species I took flying near Lyndhurst in the
New Forest the end of August 1822. Mr. Haworth has also
taken it in the neighbourhood of London. My specimens per-

fectly accord with each other ; but it must be exceedingly va-
riable if Jurine be correct in considering Trypoxylon equestre
Fab., Psen rufa Panz., and his own P. bicolor, the same
species. P. ater is another species found in the vicinity of
London upon posts and in sandy places in June and July ;
and Mr. Stephens has two others unnamed, which he con-
siders distinct.

Jurine has made two divisions in this Genus : the first con-
tains P. ater, with the second submarginal cell receiving the
first recurrent nerve only ; the second contains P. equestris, in
which the second submarginal cell receives the two recurrent
nerves. Not having had an opportunity of examining a male
of this Genus, the number of joints in the antennae of that sex
is given upon the authority of Jurine. The three lobes men-
tioned by Latreille in his observations upon the Larradce, I
could not discover in the lip of the species that I dissected ;
and he does not mention that organ in his generic description.
The females from which the characters and figures are taken
are armed with sharp stings, that are not entirely concealed.

The plant figured is Ranunculus Ficaria (Common Pilewort).

In the Author's and other Cabinets.

The Cercerides are well characterized by the singular form
of their abdomens, the segments being coarctate, or girted in
at their margins, and the petiolated submarginal cell of the
superior wings will also distinguish them from neighbouring
genera *.

They are generally found in sandy and heathy situations ;
and the males, which have an additional joint to their antennae
as well as to their abdomens, are much rarer than the females,
from which they also frequently vary in their markings.
They nourish their larvae (Latreille informs us) with the dead
bodies of the Andrenae (a genus of bees, plate 129), which
they place at the bottom of their nests in the manner of the
Sphecidas.

Our British species are

1. C. laeta Fab. mas. — Curtis Brit. Ent. pi. 269. Jem. —

aurita Fab. Jem. — Lat.
The females of this insect were abundant last August,
entering holes in sandy places at the back of the Isle of Wight,
and also at Ramsdown in Hampshire; but it is remarkable
that I never saw a single male.

2. C. quinquecincta Fab. mas. — Panz. 63. 12. — quadricinc-

tus Panz. 63. 15. Jem.
Found in June in sandy places, also in July, I believe, by
Mr. Dale on Parley Heath.

3. C. labiata Fab. — Panz. 63. 16.—Stur?n Verz. t. 3. J. 7.
This species with its singular labrum I have taken in Nor-
folk.

4. C. quadrifasciata ? Fab. — Panz. 63. 14-. mas.

I took a male flying amongst heath the 30th July.

5. C. ornata Fab. — Panz. 63. 10. Jem.

I once met with this insect either in Norfolk or Suffolk.
The plant is Mentha rotundijolia Smith (Round-leaved
Mint).

* The dissections were made from a female, and in some of the plates the 5th
and 6th joints of the maxillary Palpi are wanting, the first specimen examined
having been injured.

In the Author's Cabinet.

Philanthus was not known to inhabit this country until last
autumn, when I discovered specimens at the back of the Isle
of Wight, and afterwards near Heron Court, in company with
the Hon. Charles Harris, the middle and end of August. They
were either resting upon the ground amongst multitudes of
bees (Andrena2, &c), and of the Cerceris lately figured, or
were flying over grassy places at the borders of a corn-field,
and settling upon Hawk's-weed and other flowers.

Latreille's account of this fine insect is too interesting to be
omitted. They do not, it appears, live in society, but both
sexes are found upon flowers in sandy districts ; the female
burrows in the earth; and placing a bee there, most commonly
an Andrena, which she has killed, deposits an egg near and
closes up the hole.

The same author says, the P. apivorus (which is our insect)
is a dangerous enemy to the hive-bee. The females dig, in
light soil, on a declivity exposed to the sun, a gallery almost
horizontal, and about a foot deep ; she employs her mandibles
and her feet to raise and remove the earth, which is collected
as she proceeds with her labour. When their nest is finished
they go and search the flowers to find a bee, which they kill
by piercing it with their sting where the head or abdomen is
united to the thorax, and afterwards carry it to the end of
their burrow. As each female lays at least five or six eggs, it
follows that the same number of bees are destroyed; and con-
sequently when they abound in the neighbourhood of hives, it
is probable that they do great mischief.

Melampyrum arvense (Purple Cow- wheat), the local and
beautiful plant figured, I have gathered from the end of July
to the beginning of September, in corn-fields at the top of the
Cliff in the neighbourhood of Niton in the Isle of Wight,
where it is sometimes so abundant that the bread is discoloured
and rendered unwholesome by the vast quantity of the seeds
which are mixed with the wheat.

Some wasps, like the bees, live in society, constructing nests
composed of cells, but formed of very different materials. The
Odyneri on the contrary do not unite to form a nest to live
in, whence they are called Solitary Wasps : their economy,
however, is exceedingly curious, and they exhibit a degree of
instinct which can scarcely be surpassed. Their eggs are de-
posited in cells made in old walls or sandy banks, about which
the species may be found in June, as well as upon flowers.

My friend Mr. Charles Fox detected upon the top of a book,
across which another was laid, some cells of a somewhat trian-
gular form, covered externally with mud and formed of a silky
substance within : he very obligingly transmitted the book to
me last winter, and in the spring nearly 20 specimens of the in-
sect figured made their appearance; they were all females, and
did not vary in the least. I have no doubt of their being the
Vespa parietinus of Linnaeus' s Faun. Suec. of which there is no
figure that I am acquainted with, Panzer's V. parietina being
the V. muraria Linn. It is very easily distinguished from our
other species by the unclouded wings and the entire orange
underside of the antennae.

In the Cabinets of Mr. Dale and the Author.

The genus Eumenes is composed of those Wasps which are
solitary in their habits ; not congregating and forming nests,
like the common Wasps and Hornets ; Fabricius in his Sy-
stemaPiezatorum described 23 species, 3 of which are European,
and Panzer has added 3 or 4> more to them ; but it was not
recorded as a British genus until my friend the Rev. W.
Kirby (equally celebrated for his invaluable works and for
his acute observations) discovered it in an entomological ex-
cursion with Mr. Dale upon Parley Heath, on the borders of
Hampshire, July 3, 1821; — at the end of August 1822, I
captured 2 on the same heath upon gravelly and dry banks ;
and earlier in the last year, I am informed by Mr. Bentley, it
was found by him settling upon different species of Ericae
which are common in such situations.

Eumenes may probably at a future period be separated into
two genera ; but as I cannot detect any important differences
in the Trophi after the most careful examination, I shall only
propose to make 2 divisions of them: the 1st may contain the
species with a long petiole to the abdomen; the 2nd (to which
our Insect belongs) those with the 1st segment short and funnel-
shaped, of which the parts composing the mouth agreeing with
the habit of the Insects, are more robust and obtuse than in
the 1st division.

The plant figured is the beautiful Erica Tetralix (Cross-
leaved Heath).

Rufa Linn. — Curt. Guide, Gen. 697. 3.

Wasps, like the hive-bee and ants, live in societies, which
consist of three different kinds of individuals, males, females,
and neuters or workers. The male wasp has no sting, is as
long as the female, but much more slender and elegant in form,
and more handsomely marked with black ; the female is the
largest sex and armed with a sting, as is also the neuter,
which is a miniature likeness of her.

The female lives through the winter, and deposits her eggs
early in the spring in cells formed by herself ; these eggs, ac-
cording to the observations of authors, produce only neuters,
which immediately form a colony or nest; the males next ap-
pear, and afterwards the females. Wasps scrape posts and
timber to form their nests ; they live upon fruit, will eat meat,
and they are very dexterous in catching flies.

The insects that inhabit their nests, and probably prey upon
the larvae, are Dromius linearis (fol. 231); Rhipiphorus para-
doxus (pi. 19), supposed by the Rev. E. Bigge to have been
an Ichneumon; Anomalon Vesparum (pi. 198); and the larva
of Volucella inflata ? (pi. 4-52) ; and on the Continent V. gal-
lica is infested with a Xenos.

1. V. Crabro Linn. — Don. 14. pi. 502. The hornet is found
in May, August, September, and October, and builds its
nest in hollow trees and in thatched roofs.

2. vulgaris Linn. — Don. 7. pi. 226.? — Panz. 49. 19? Found
from March to December, and builds its nest in the ground,
of fibres of wood scraped from sound timber, as observed
by the late Mr. T. A. Knight.

3. rufa Linn. — Curt. B. E. pi. 760. J1 and ? .

Male black, clothed with silky hair : antennae with a yellow stripe on the
inside of the basal joint and a dot at the apex ; orbits of eyes, excepting
the upper internal portion, a subquadrate space between the antennae,
outside of mandibles and clypeus yellow, the latter nearly divided by a
long trilobed spot: margins of collar, scapulars, 2 spots below them, and
2 on the scutel yellow : abdomen bright yellow, the black basal bands and
spots more or less edged with ferruginous ; basal segment black only next
the thorax with 3 black spots across the middle, 2nd and following seg-
ments with a black band at the base, and a black dot on each side, the
2nd with a large black spot in the centre united with the band, the
remainder angulated only in the centre and decreasing in depth : costa
and some of the nervures yellowish, the others brown, stigma pale fer-
ruginous : legs deep yellow, coxae, trochanters, and thighs, excepting the
apex, black ; inside of tibiae ferruginous, anterior with a black streak.
Female black, spot on the clypeus anchor-shaped (R) ; no yellow spot
at tip of basal joint of antennae, the stripe very narrow ; no black bands
visibel, except on the 2nd segment, but there are semicircular streaks on
the 3rd and 4th, the dorsal spots larger ; 1st and sometimes 2nd pair of
tibiae with piceous patches on the inside. Neuter, spots on the clypeus
more or less anchor-shaped ; no yellow streak on the antennae : abdo-
men like the female, but the spots on the basal segments are more or
less, sometimes entirely ferruginous ; tibiae seldom piceous inside.
At once distinguished by the anchor-shaped mark on the
face, which is represented only by a spot in V. xndgaris. It
constructs its nest of rotten wood, and I once found an im-
mense number under a clod of earth. The 3 lines in the
plate show the length of the sexes.

globose, 3rd scarcely larger, the remainder subquadrate, slightly
increasing in diameter, apical joint conical (1): 12-jointed in
the females basal joint long and slender, 2nd and 3rd of equal
size, the remainder transverse or quadrate, terminal joint coni-
cal (1 a).

Labrum transverse-oval, ciliated with rather broad but acute
bristles (2).

Mandibles slightly curved, hairy, bifid at the apex (3).
Maxillce ; the stalk long, terminated by a short bent ovate lobe,
acuminated and ciliated with long bristles at the apex (4). Palpi
long and 6-jointed, basal joint scarcely so long as the 2nd, which
with the others are of nearly equal length, excepting the terminal
joint which is a little longer and very slender, the 4th and 5th
clavate (b).

Mentum long, subelliptical, acuminated before in the centre (5).
Lip very short, with a lobe on each side (c). Palpi rather short,

in the anterior pair notched on the inside at the base and pectinated.
Claws simple. Pulvilli distinct (8, a fore leg).

The convex and almost naked bodies of these little insects
give them so different a habit, and the structure of the labium
is so dissimilar to the rest of the family (excepting Colletes,
pi. 85), that they have been placed at the commencement of
the Andrenidae both by Mr. Kirby and Mons. Latreille.

The following British species I shall characterize, as far as
I am able.

In the Author's and other Cabinels.

Independent of the differences in the mouth, Colletes may
be instantly known from the two genera which it most resem-
bles externally, Andrena and Halictus, by the equal propor-
tions of the 2nd and 3rd submarginal cells, one of which is
small in the former, and by those cells receiving recurrent
nerves, which is not the case in the latter.

We have 3 or 4 species of Colletes in Britain; viz. 1. suc-
cincta Linn. 2. fodiens Kirby. 3. Daviesana Kirby's MSS.
and a species in my cabinet, which appears to be very different
from the foregoing.

The males of C. fodiens I took upon the elevated cliffs at
Christchurch, Hampshire, that are covered with heath, about
the middle of August ; and a few days after I met with the fe-
males in abundance flying about the western side of a bank
upon Parley Heath in the same county, but saw no males.
Although this species has been figured in Monographia Apum
Anglice, the beautiful state of the females that I took has in-
duced me to give one as an example of the genus. I can
scarcely think that the insects figured by Panzer, fasc. 105.
11. 21 & 22, can be the Melitta fodiens of Kirby ; they are too
black, the scutella are pale, and the female wants the light spots
upon the basal segment of the abdomen.

We are indebted to Reaumur for a knowledge of the eco-
nomy of these bees, and it is a little singular that no one ap-
pears since his time to have been able to discover their nests,
which they form amongst the earth that fills up the spaces of
some stone walls ; they are cylindrical, and composed of many
cells of different lengths, placed in a horizontal line, each cell
being formed like a thimble and fitted to the next : sometimes,
however, when a stone obstructs their course, the line becomes
irregular. The cells have alternate transverse bands of two
or more colours; the shorter ones at their junction are white,
the longer ones enveloping the body are reddish brown.
These cells are constructed of many layers lying one over the
other ; and although their contexture is close, they are very
transparent, in consequence of their extreme thinness, — suffi-
ciently so to discover the colour of the substances contained
in them, which causes the variegated line above described.

The plant figured is Campanula glomerata (Clustered Bell-
flower).

Males smaller and more slender than the females. Ocelli 3, nearly in
a transverse line. Eyes lateral and narrow. Head not broader
than the Thorax, which is subglobose. Abdomen ovate-conic in the
males, ovate and depressed in the females and fringed at the apex.
Wings with 1 marginal and 2 submarginal cells. Tibiae furnished
with long spurs, very pilose, especially the hinder pair in the female,
as well as the basal joint of the tarsi in that sex. Tarsi 5 -jointed,
the basal joints very long especially in the 4 posterior of the males
and dilated, particularly in the females. Claws bifid at the apex in
the males. Pulvilli distinct. (8, fore leg of female.)

These handsome insects approach considerably in form some
of the Andrenee, but they are easily distinguished by having
only two submarginal cells. The sexes differ so widely, that
they have been described under various names: the upper
figure in our plate is the male, and the lower one the female,
which I shall here describe.

D. S wammerdamella Kir. 2. 174?. Ill . — Curt. Guide, Gen. 70 1 .
Male. A. farfarisequa Panz. 55. 14?. — hirta Fab.
Black and minutely punctured; the pubescence long, pale
ochreous or ferruginous; silvery white and combed down over
the clypeus: abdominal segments with the margins fringed
with pale hairs; nervures ferruginous and piceous: spurs and
hairs on inside of basal joint of tarsi orange, terminal joint
and claws ferruginous, the latter tipped black.

Female. D. hirtipes Fab. — A. plumipes Panz. 46. 16,
and A. succincta 7- 10.
The pubescence on the crown of the head and thorax ful-
vous : basal joint of abdomen clothed with pale hairs, the 3
following ciliated with whitish hairs, slightly interrupted down
the centre, the 5th joint densely clothed with black hairs ex-
cept at the base : 4 anterior tibiae and basal joint of tarsi clothed
with fuscous hairs, orange beneath ; hinder pair with the tibia?
and basal joint of tarsi perfectly concealed by long orange
hairs.

This insect, which I believe is never met with in the North
of England, I have found at the back of the Isle of Wight,
flying about and settling on the Hawk's-weed on the top of
the Cliff the whole of August; at Frejus in France the 5th of
July, and on the sand hills at Calais the end of August. Cap-
tain Blomer sent me specimens from Devonshire, and many
years since Mr. Kirby used to find them at Barham in Suffolk
on the flowers of the Ragwort. In his Monograph are the
following observations : " In the month of August 1 797> I saw
a female take her flight from a grassy declivity of a southern
aspect, which was much entangled with roots and shrubs.
Upon examining this spot more narrowly, I discovered a
number of small burrows, each of which had a little heap of
sand, which had been excavated from it, lying before it. In
some of these burrows I saw our Melitta sitting, with her head
at the mouth, enjoying the sunshine ; at the same time I ob-
served many other insects flying about the spot. Upon my
attempting to take them they disappeared, but they soon re-
turned so their amusement. With some difficulty, I at length
succeeded in taking one, and it proved to be the male just
described."

On the Continent there are several species of our genus, and
last year I had the pleasure of capturing both sexes of the
D. discincta of Illiger, the A. Visnaga of Rossi. I found this
fine insect in July on the flowers of a Thistle near Frejus, and
I believe Mons. Marcel de Serres takes it near Montpellier.

The Plant is Tussilago Farfara (Colt's-foot).

In the Cabinet of Mr. Stephens.

There are about 80 British species of this well-known genus,
of which we have upwards of 50 named in our own cabinet :
most perfect descriptions are given of them in the 2nd vol. of
the Monographia Apnm Angliec the following have been
detected and named by Mr. Kirby since the publication of
his valuable work, viz. Andrena Hallana, fulvescens, albe-
scens, Spencella, and Yeatella. The reader will also find an
account of the habits and economy of this group in the 1st
volume, p. 141 of the same work, of which we shall here avail
oui'selves. " The species of this family usually nidificate
under-ground in a light soil, some choosing grass banks over
which bushes are scattered, others bare perpendicular sec-
tions, but all seem to delight in a south aspect. They exca-
vate cylindrical burrows from five inches to near a foot in
depth, and of a diameter sufficient only for the Melitta
[Andrena) to go in and out at. When they make these holes,
they remove the earth grain by grain, which forms a small
hillock near the mouth; they sometimes run in a perpendi-
cular, and at others in a horizontal direction. The cell at
the bottom of these burrows they replenish with pollen made
into a paste with honey, and in this they deposit their eggs.
The pollen they carry not only upon the scopa of their pos-
terior tibiae, but also upon their flocculus, and the hairs of their
metathorax." — The student will be well rewarded in collecting,
by visiting the Sallows when in flower as early as April ; and
as the males and females are exceedingly different, he should
take care to discover if possible the sexes, — many species are
attached at later periods to syngenesious and other flowers.

The rare insect figured was in the collection of the late
Mr. M. Griffin of Norwich, and was probably taken in the
neighbourhood of that city : it now enriches the cabinet of
Mr. Stephens, with whom I unite most cordially in naming it
after the gentleman to whom we are so greatly indebted for
our perfect knowledge of this interesting family.

I feel great pleasure also in introducing a drawing of Mes-
pilus Cotoneaster, which I am enabled to do through the kind-
ness of my friend Professor Henslow, who has obligingly com-
municated specimens, and the following account from W.
Wilson, Esq. of Warrington, Lancashire, who discovered
it last year in Wales. " The surface of the Orme's head is
broken into cliffs and ledges, and upon these cliffs the Mcspilus
grows. It is most abundant within half a mile of the village
of Llandidus, but occurs, though much more sparingly, in
other parts; and I have seen it at the N.W. extremity of the
head. It is indisputably indigenous. The Orme's head con-
sists of limestone."

In the Author's Cabinet.

This singular and I believe nondescript species appears to
form a beautiful connexion between the Andrenidae and Apidae,
but unfortunately the female is unknown. I took 3 males at
Ventnor in the Isle of Wight, flying about flowers near the
sea-shore, the 12th September 1826, and one of them was Sty-
lopsed ; they look very long on the wing, in consequence of
the head, antennae, and bodies being carried horizontally.
Those parts that I have not described or but slightly, are si-
milar to Halictus, which I shall now illustrate.

HALICTUS.

Type of the Genus, Melitta rubicunda Kirby.
Halictus Lat., Curt. Guide, Gen. 704. — Andrena Panz. — Hylseus,
Megilla, & Anthophora Fab. — Melitta Kirby.
Antenna inserted near the middle of the face, long filiform and
13-jointed in the males (1 ; basal joint the longest and clothed
•with long feathery hairs, 2nd cup-shaped, 3rd semiovate, 4th
stouter and oblong, the remainder slightly decreasing in length
and becoming very ovate or convex on the underside, terminal
joint rounded at the apex : shorter and geniculated in the fe-
males (19), pubescent and 12-jointed, basal joint very long,
clavate and pilose externally towards the base, 2nd small obo-
vate, 3rd a little broader, the remainder stouter and subquadrate,
terminal joint subovate.

Labrum short, transverse and convex in the males (2), the sides
rounded, ciliated before with long flat hairs : producing a sub-
lanceolate lobe in front, ciliated with long hairs dilated at the
base in the females (2).

Mandibles rather slender in the males (3), sublanceolate, curved
and crossing, produced inside at the base, externally pilose :
sublinear in the females (3), hollowed inside, truncated obliquely
at the apex and notched, externally pilose.
Maxilla alike in both sexes (4), very long, terminated by a
small bent lobe, subovate with a notch on the inside and ciliated
■with longish hairs. Palpi (b) twice as long as the lobe, slender
and slightly attenuated, 6-jointed, the 3 basal joints shorter
than the following.

Mentum alike in both sexes, long and linear (5) . Lip short ovate-
conic, being pointed and pubescent at the apex (c). Paraglossts
as long as the lip, subelliptical, rounded at the apex and ciliated
(d) . Palpi nearly twice as long as the Up, slender, attenuated
and 4 -jointed, basal joint the longest and stoutest, 3 following
short and of equal length (6).
Males smaller and slenderer than the females. Head orbicular, depressed:
eyes long and ovate: ocelli 3. Thorax globose. Abdomen ellip-
tical in the males (6 (J) ; ovate conic in the females, with a groove on
the back at the apex (69)- Wings; superior with one marginal
and 3 submarginal cells, the central celt the smallest. Tibiae, with
long spines or spurs, posterior robust in the female : tarsi 5-jointed,
basal joint long and stout in the females, the others minute. Claws
bifid in both sexes.

The remarkable elliptical impression on the back of the penul-
timate segment of the abdomen distinguishes the female Halicti
from all other Bees, and the head of the male is narrower and
more elongated than in Andrena, and the 3rd joint of the an-
tennae is not much larger than the 2nd. The Paraglossae were
entire at the apex in the Halicti that I dissected, but Mr.
Kirby has represented them as lacerated at the apex.

This genus contains 29 British species, for the names of
which the student is referred to the < Guide'. It is singular that
not one of them appears to have been described by Linnaeus.

The Plant is Plantago lanceolata (Ribwort Plantain).

In the Author's and other Cabinets.

The uniformity that prevails in the structure of these bees,
especially in the similarity of the palpi and the antennas of the
sexes, renders it easy to distinguish them from the other Apidce^
and nothing can be more natural, I think, than the situation
assigned to them by Mr. Kirby, for in habit they so much
resemble Dasypoda, that Fabricius (who must have judged in
this instance from analogy and not from dissection, as the
mouth assumes the more developed form of the Apida:) had
included them in his last work in that genus ; and on the other
side they approach very near to Nomada, in the form of the
palpi and other parts of the organs of manducation.

We have but 2 species of this genus ; for as Apis ursina,
and A. Banksiana of Kirby are constantly found together, the
former being all females and the latter all males, it cannot be
doubted that they are one species.

1. Panurgus ursinus, Mr. Kirby took upon a heath in Suffolk,

in September, and in the middle of June I captured
several of both sexes upon a sunny bank near
Shooter's Hill. The female having been figured in
the Mon. Ap. Angl. tab. 16. f. 1., I have preferred
giving the male, being in doubt about Panzer's figure
of Trachusa atra,fosc. 96. pi. 19. all the tibiae being
destitute of the fulvous pubescence.

2. P. lobata Panz. Both sexes of this rare insect are well

figured in his Faun. Ins. Germ. Jasc. 96. 18. male,
and 72. 16. female. Having received specimens
from Germany, and Mr. Stephens having allowed
me to compare his specimen, which was the one in
the late Mr. Marsham's collection, referred to by
Mr. Kirby, there can be no doubt of their being the
same species, alth6ugh the figure in the Mon. Ap.
Angl. tab. 16. f. 2. does not show the spines on the
posterior thighs, as exhibited in our plate (fig. 8f ),
which are quite concealed, except when the legs are
spread out ; a proof of the utility of setting insects
well when first taken, or of relaxing them after-
wards, as recommended by Mr. Samouelle in his
Useful Compendium, p. 321.
The female of P. lobata I have never seen ; the males have
been taken in September upon Martlesham Heath, near
Woodbridge, Suffolk, by Mr. Kirby, whose specific name
would most willingly have been adopted, had not Panzer pub-
lished his previously. Latreille observes, that our bee is fond
of semiflosculous flowers ; we have consequently figured Ci-
neraria integrifolia (Mountain Fleawort), communicated by
Professor Henslow from the Goffmaffog Hills.

Mandibles bifid at the apex, short and externally hairy in the
male (3), long curved and porrected in the female and very

Florisomnis Linn. $ . — maxillosus Linn. $ . — Curt. Guide, Gen. 709.
Black, shining, thickly and minutely punctured, slightly clothed
with ochreous down, hinder margin of wings brown, nervures
piceous : male with the face densely clothed with soft yellow
hairs, abdominal segments fringed with whitish hairs on the
sides, underside of 4th segment ochreous : female with the in-
ternal margin of the mandibles ciliated with ferruginous hairs
as well as the hinder tarsi ; underside of abdomen clothed with
ochreous hairs, the segments neatly margined with white above,
interrupted down the back.

Since Mr. Kirby wrote his able Monograph, his suspicions
have been confirmed relative to the sexes of this bee having
been described by Linnaeus under two names, yet the fact of
Mr. Shuckard having seen the female Chelostoma paired with
an Osmia, shows how difficult it is to ascertain the sexes of in-
sects, and how cautious we ought to be in deciding on such
questions.

It is said that the idle males of this singular bee sleep away
a great portion of their time in the bosom of some pretty flower,
whilst the female labours hard with her mandibles to form cells
several inches in length in posts and rails, where she deposits
her eggs, supplies them with pollen, and then dies. By the
following extract from a letter written by the Rev. R. Albion
Cox to Mr. Dale, it is evident that they sometimes save them-
selves the labour of excavation by employing the stubble of
wheat for their nests, a remarkable departure from their usual
ceconomy which has not been hitherto noticed. " The habits
of this species (says Mr. Cox) are singular, the reed-motes
contain their nests. On splitting a portion from one you will
find a most ingenious arrangement for the support of the in-
fant progeny. First a store of pollen, then an egg or grub,
and lastly a small pellet of earth or stone, and so on in a se-
ries from the joint to the end of the straw, which is carefully
sealed. The pellet is placed in the position described, evi-
dently for the purpose of intercepting the progress of the larva
in that direction, lest he should infringe upon the rights of his
next-door neighbour. If you should chance to meet with a
straw whose inmates are in a more advanced stage, you will
find the pupa inclosed in a silken shroud at the end opposite
to his original position, and behind him the rejectamenta of
his banquet. Whatever may be the diameter of the straw, the
quantity of food appears to be precisely the same; whence it
happens that the deposits differ in length, proportionably to
the size of the cylinder which contains them." Mr. Cox adds,
" Mr. Paulett Mildmay first pointed out the ingenuity of the
contrivance."

Mr. R. Bakewell, of Nottingham, also informs me that the
females of Sapyga clavicornis (pi. 532.) enter the holes of Che-
lostoma, and are always to be found about posts where that
bee nidificates, but the male Sapyga is very rare and difficult
to capture.

The Ichneumon manifestator, Fcenus jaculator (fol. 423.),
Ichneumon femorator, Kirb., and Chrysis cyanea are recorded
also as parasites on the larvae of Chelostoma.

For the pretty plant, Exacum Jiliformc, Least Gentianella,
I am indebted to the Hon. C. A. Harris.

Truncorum Linn. — Curt. Guide, Gen. 710. 2.

In the Cabinets of Mr. Kirby and the Author.

IIkriades is distinguished from the other Apidao by its labial
palpi, which are only triarticulate, and the basal joint is very
short. The Paraglossia? are also short, and I could not discover
any in the male.

There are two species inhabitants of this country, and they
are supposed to nidificate in posts, rails, holes in old trees, &c.

1. H. Campanularum Kirb. Mon.pl. 16./. 14 & 15.? &<?.
Shining, thickly and minutely punctured, and sparingly
clothed with minute ochreous pubescence; the face and espe-
cially the clypeus producing long ochreous hairs in the male,
and the margin and underside of the abdomen in that sex, ex-
cept at the base, are thinly covered with yellowish hairs, but in
the female they are long and thick ; wings fuscous round the
margins, the nervuresand stigma piceous; spurs ochreous, the
basal joint of tarsi producing long whitish hairs in the female,
especially the intermediate, inside of the same joint in the pos-
terior clothed with bright ferruginous hairs ; claws subfer-
ruginous.

"This little Apis," (says Mr. Kirby,) "by far the most mi-
nute species of this genus that I have yet seen, is common,
during the summer and autumnal months, in the blossoms of
Campanula Trachelium, rotundifolia and hybrida, and what
deserves to be remarked, I never found it in the flowers of any
other genus of plants. The males are often taken asleep in
these flowers ; their abdomen is then doubled, so that the tu-
bercle, with which its base is armed, fits into the cavity near
the anus." On the 29th of June I once found it in abundance
in a garden at Fulham.

2. H. truncorum Linn. — Panz. 64-. 15. — Curt.B.E.pl. 504 ? .

Female slate-black, slightly pubescent with whitish hairs,
and closely covered with strong punctures, especially the head
and thorax, a spot of long white hairs on each side the clypeus,
sides of thorax similarly clothed. Abdomen concave at the
base, with a transverse ridge and another at the base of the 2nd
segment, the anterior margin of the 1st clothed at the sides
with white pubescence, sometimes extending across, the 3 fol-
lowing segments ciliated with white hairs, forming very narrow
bands, the pubescence at the apex very short and ochreous, the
pubescence beneath as well as on the basal joint of the hinder
tarsi ferruginous ochre : wings tinged with brown, especially
across the middle; nervures and stigma piceous, spurs ochre-
ous, tips of tarsi and claws ferruginous. " Male smaller: cheeks
unarmed : maxillae not carinated above : abdomen with the
margins of the anterior segments whitish : anus inflexed, last
segment entire, somewhat compressed with a little transverse
fovea on each side : belly with white hairs at the base, convex,
with a tolerably deep cavity at the apex." — Kirby.

As I have never seen the male, the above description is
translated from Mr. Kirby's Monograph : the female very
much resembles the same sex of Osmia leucomelana, but is
rather more slender; the head is proportionably larger; it is
more strongly punctured, and the hollow space above at the
base of the 1st abdominal segment at once distinguishes it.

Taken at Brentford : I believe my female came from Norfolk.

The Plant is Campanula (Prismatocarpus L'Hcr.) hybrida,
Corn Bell-flower.

No family of insects has excited greater interest, been better
investigated, or more clearly understood than the bees, — cir-
cumstances arising no less from their wonderful economy and
beautiful organization, than from the labours of some of the
species supplying us with the luxuries and necessaries of life ;
at once affording both instruction and amusement to the na-
turalist, and speculation and profit to the merchant.

Whilst war like a frost (if I may be allowed the expression)
locked up the streams of knowledge that during the suc-
ceeding peace flowed in kindly harmony to instruct and benefit
mankind, two of the most illustrious entomologists of the age
were (unknown to each other) investigating the same subject;
and it is delightful to see how those who take nature and truth
for their guides arrive at the same conclusions, although some-
times led by different ways. The most perfect production
that ever appeared in this country was at that time given to
the world from the pen of Mr. Kirby, a work which it is far
more easy for me to admire than to praise as it demands : in
that work the student has a noble example of a monograph ;
his mind is directed " to look through Nature up to Nature's
God ;" and so complete is the mass of scientific information,
that little appears left to be done by future writers. At the
same time Mons. Latreille was employed in arranging the
family, including the exotic genera, and naming the groups,
which first appeared in his " Histoire Naturelle" vol. 3.;
and in his subsequent works, the " Genera Crnstaceorum" and
" Considerations Generates" this admirable undertaking was
perfected. With these advantages over every other family of
British insects, it is no wonder that the Apidcz should become
the favourites of the entomologist ; I confess they are so with
me, and I anticipate much pleasure in the illustration of them.
The genus now selected is extremely interesting in its habits
of life; for a detailed account of which I must refer to Kirby's
" Mojwgraphia Apum Anglice" remarking that it is the only
species of the genus found in this country. It is by no means
a rare insect in the neighbourhood of London. In the months
of July and August 1823 Dr. Stephenson took it in great
abundance in lanes at South Lambeth and Chelsea : I am in-
formed by him that it occurs chiefly on dry sandy weedy
banks ; and like most insects of this tribe, it may be taken on
the wing during the whole of the day when the weather is
fine, occasionally settling on various plants, especially those
that are covered with short woolly hair or down, the Stachys
sylvatica (PI. 65.), Glechoma hederacea, &c, the tomentum of
which it strips off for the purposes of nidification, forming its
nest in hollow trees and other situations.

Mr. Kirby having observed it to frequent the Agrostemma
Coronaria (an Italian Plant), I have figured an English spe-
cies of the same genus, A. Githago (Corn Cockle).

In the Author's Cabinet.

I have the satisfaction of again referring my readers to the
following works for the histories and descriptions of these
bees, viz. Reaumur, torn. 6, Mem. 3; and the Monographia
Apum Anglite, vol. 1. p. 178, and vol. 2. p. 260, from whence
we learn that they build their nests upon the uneven surface of
walls, and construct their cells of mud which has caused them
to be called Mason-bees. Although Osmia is nearly related
to Megachile, there are considerable differences in the trophi,
the most important of which is the 4-jointed maxillary palpus ;
and there are external characters, such as the longer antennae
and more woolly bodies of the males, and the more ovate and
convex bodies of the females, which will be found useful to
distinguish them.

In addition to those described by Mr. Kirby, I have had
the good fortune to discover two others which appear to be
nondescripts. The genus may be arranged in the following
order :

1. O. hirta Fourc. — Leaiana Kirby. August and beginning

of Sept. Thistles, Suffolk, and Isle of Wight.

2. spinulosa -Kz'riy, tab. 17. J. 1 &2. August. Sand and

chalk pits near Ipswich, Suffolk.

3. leucomelana Kirby. Amongst pines, and on flowers of

Dandelion : Suffolk. July and August : upon Cen-
taurea, and under the cliffs at Dover.

4. caerulescens Linn., Panz. 65. 18. fern. — aenea Panz.

56, 3, masc. July ; in chalky and sandy places.

5. parietina Curtis Brit. Ent. pi. 222. fern. Beginning of

June ; flying about walls near Ambleside.
With the male of this bee I am unacquainted ; the female
resembles in size and colour the same sex of O. hirta, but the
pubescence of the thorax is ferruginous, and the hair with
which the underside of the abdomen is clothed is black.

6. Tunensis Fab. — aurulenta Panz. 63. 22. Jem. July;

on clayey banks.

7. bicolor ScAr.^-fusca Panz. 56. 11. Jem. — hasmatoda

July ; gardens and sunny banks.

8. atricapilla Nob. — I have only a female of this insect

taken by myself ; it is black, the thorax and base of
abdomen fulvous.

9. bicornis Linn. — fronticornis Panz. 63. 20. Jem. var. — rufa

Panz. 56. 10. masc. — cornuta Lat. March, April,

men with the segments whitish at their margins, the hairs beneath
bright ferruginous, black at the apex (6). Anterior feet simple.

The large mandibles of these Bees have supplied the generic
appellation of Megachile, which lias been retained in justice
to Moris. Latreille, although Mons. Dumeril's name of Phyl-
lotoma (Leaf-cutters) is more characteristic. They all form
their nests either in decaying trees or under ground ; and the
skill displayed by these little animals in cutting the petals of
flowers and the leaves of plants to construct their curious cells
is so wonderful and interesting, that the reader will be highly
gratified by referring to the following works, which contain
their histories : namely, Reaumur, torn. 6. Mem. 4; Donovan's
" British Insects," vol. 4. p. 31 ; Kirby's " Monographia Apum
Angliae," voL 1. p. 156. and vol. 2. p. 244; and Kirby and
Spence's "Introduction to Entomology," vol. 1. p. 438 or 441.
The following are British species of Megachile :

1. Willughbiella Ray, Kirby, Nob.

Inhabits the decaying trunks of Willows in low meadows :
found in July in Suffolk, and on the banks of the Thames, at
Brentford, Fulham, &c.

2. centuncularis Einn., Fab., Kirby. — Schcef. Icon. 262. f. 6. 7.

— Harris, Exp. t.^9.f.2.
The nests of this Bee are formed in walls and decayed trees;
the cells are composed of the leaves of roses, the Laburnum
and Mercurialis annua. They are found in August upon
Thistles.

3. Leachella Kirby's MSS.

The smallest species of the genus, and may be the M. Pa-
paveris Lat. Specimens are preserved in the British Museum.

4. maritima Kirby Mon. Ap. Ang. 2. 242. 43.

Taken near Landguard Fort, on the coast of Suffolk, in
July.

5. ligniseca Kirby 2. 243. 44. tab. 16. f. 11. mas. — argentata?

Panz. 99. 16. mas. — centuncularis Panz. 55. 12. Jem. —
Don. 4. pi. 120.
Found in September. It forms its cells of the leaves of roses
and of elms, in the trunks of this tree and of the oak also.

6. circumcincta Kirby 2. 246. 45, tab. 16. f. 10. fern.

This Bee was first discovered by the Rev. Dr. Goodenough
(the late Lord Bishop of Carlisle), in the month of May, on a
bank of a southern aspect at Dartford in Kent. I once dug
some of the centunculi out of a bank on the beautiful domains
of Lord Stafford, at Costessey in Norfolk : they were formed
of rose leaves.

A single specimen was taken by the Rev. W. Kirby in July,
creeping upon a clay bank at Somersham, near Ipswich, Suffolk.

In the Author's Cabinet.

These bees, with several others, are supposed to be parasitic,
but nothing I believe is known of their economy. I have fre-
quently dug them out of the earth, late in the year, in a dead
state : they were buried very deep, the holes being made on
the perpendicular side of a cliff, and the galleries ran horizon-
tally, but whether they were formed by themselves or they had
merely taken possession of them, I could not ascertain.

The males of Ccelioxys and Anthidium (pi. 61.) are distin-
guished by the denticulated apex of their abdomens, and the
cleft and gaping ones of the females are peculiar I believe to
our genus and to Epeolus.

I suspect there are several species of this genus in Europe,
but only two have been discovered in this country.

1. C. conica Linn. Panz. 55. 13. mas. — 4-punctata Linn. Fab.

Panz. 59. 1. Jem.

Male black, clothed with soft yellowish cinereous hairs;
head and thorax very thickly and strongly punctured, the
former sometimes with the pubescence of the face ochreous :
abdomen more glossy, and finely punctured, and less pubes-
cent, with a scale on each side at the base fringed with white,
the margins of the other annulations fringed all round with
white, excepting down the back where they are interrupted or
meet in a point; penultimate joint with the angles acuminated,
the apex notched semicircularly (7*). Female with the basal
tuft of cinereous pubescence larger, the white fringe very nar-
row and not interrupted down the back; apex acute, the lower
valve twice as long as the upper one (6*).

Inhabits flowers, and is not uncommon the end of June and
beginning of July.

2. C. inermis Kirby Mon. 2. 229. 38. t. 16. f. 8. mas.
Black, scutellum unarmed : abdomen of the male linear,

margins of 4 of the segments white, interrupted above, con-
tinued beneath : apex with several spines. Kirby.

This is supposed to be a variety of the former, and was
taken at Brentford by Mr. J. Trimmer.

3. C. Vectis Cartis's Brit. Ent. pi. 349. Jem.

This species is not only twice the size of C. conica, but the
penultimate joint of the abdomen in the male has not the an-
gles acuminated, the apex is notched more acutely, yet the
lobes are more obtuse, and the inferior spines are longer. In
the female the upper valve is curved, the lower one much
shorter, straight, and less acuminated.

I took several the beginning of August, on flowers near
Ventnor, and, flying about heath and pathways, at Black-gang
Chine in the Isle of Wight.

The plant is Arenaria media Linn., marina Fl. Dan. (Sea
Spurrey Sandwort).

EPEOLUS VARIEGATUS.

Order Hymenoptera. Fam. Apidaj.

Type of the Genus, Apis variegata Linn.
Epeolus Lat., Fab., Curt. — A\ris Linn., Kirb. — Noraada Fab., Panz.
Antenna inserted at the middle of the face, nearly alike in both
sexes, rather long, stout and velvety, 13-jointed in the male,
1 •2-jointed in the female, basal joint ovate-truncate, 2nd globose,
3rd of the same form and size as the 1st, the remainder rather
shorter and quadrate, excepting the terminal one which is as
long as the 1st, round and compressed at the apex (1).
Labrum transverse oval, with a large semitransparent spot on
each side, the anterior margin ciliated and notched at the centre,
with a small tooth at the middle and 2 above it (2) .
Mandibles rather small, curved and narrow, ovate at the apex,
with a shoulder on the inside producing 2 bristles (3).
Maxilla broad, the base ciliated internally (4), the terminal lobe
as long as the basal portion and rounded at the apex, with a
few short bristles outside (a). Palpi very minute and formed
of a single ovate joint (b).

Mentum long, narrow and cylindric, trifid at the apex (5). Lip
as long as the mentum, slender and linear (c). Paraglosscs
membranous and lanceolate (d). Palpi a little longer than the
Hp, 4-jointed, first 2 joints broad and compressed, basal joint
considerably the longest, 2nd attenuated and hairy at the apex,
3rd inserted outside the apex of the 2nd, short and slender as
well as the 4th (b).
Head short and broad: eyes large, lateral and ovate: ocelli 3 in
triangle very conspicuous. Thorax short not broader than the head,
nearly globose: scutellum short slightly emarginate, with a flat tri-
angular tooth on each side at the base. Abdomen short and ovate-
conic, 6-jointed in the male, 5-jointed in the female, and armed with
a long sting (s) and 2 elongated lobes (6 the lateral view). Wings,
superior with a short oval marginal, and 3 complete submarginal
cells, 2nd and 3rd small, of equal size, and each receiving a recurrent
nervure. Legs naked, nearly alike in both sexes, anterior the shortest,
posterior the stoutest : tibiae, anterior with 1, posterior ivith 2
spines at the apex : tarsi longer than the tibia, 5-jointed, basal joint
long, notched on the inside at the base of the anterior pair, a little
dilated and pubescent beneath in the posterior, especially in the male,
the other joints very short : claws simple.

Variegatus Linn. — Curt. Guide, G. 716. 1. — crucigeraPz. 61. 20. J.
Female. Opake black, thickly and minutely punctured and
densely clothed with depressed pubescence : face and sides of
thorax hoary ; margin of collar pale ochreous, as well as the
base of the abdomen ; a transverse spot on each side the hinder
margin of the 2 first segments, 2 on each side of the 3rd and
4th, and 3 surrounding the 5th of the same colour; the mouth,
a tubercle on each side the collar, the scapulars, the scutellum
and the lobes, castaneous ; legs rather more ferruginous : wings
tinged with yellow-brown and forming a fimbria ; nervures and
«tigma piceous.

This pretty little bee seems to connect Coelioxys (pi. 34-9.)
and Nomada (pi. 419.) ; from the former it is readily distin-
tinguished by the additional submarginal cell, and from the
latter by its conical and pubescent abdomen. There are also
other more important distinctive characters, but less visible,
such as the great length of the basal joint of the labial palpi,
with the 2nd joint acuminated, the minute maxillary palpus
of one joint, as in Anthidium (pi. 6 J .), the obtuse lobe of
the maxilla?, and the singular labium with a small tooth in
front and two above it, forming a triangle, which seem to have
escaped the observation of Mr. Kirby and M. Latreille.

It is a remarkable fact noticed by Mr. Kirby, that the male
of this bee was unknown to him. I have taken a very consi-
derable number of specimens, and am much gratified at having
discovered one male amongst them, since it enables me to state
that Panzer's figure is of that sex, and not a variety of the
female ; for my male has an entirely black labrum and scu-
tellum, with the lobes also black and less prominent than in
the other sex : the 5th and 6th segments of the abdomen have
a long transverse band of ochreous hairs entirely covering the
back, and the little apical lobe is also black. The male is as
large as the female, but the abdomen is more ovate, with 6
joints : the antennas are rather shorter if anything, although
13-jointed, and the basal joint of the hinder tarsi is clothed, I
think, with rather longer hairs.

The females seem to vary considerably in size, and the
authentic specimen in the Linnsean cabinet mentioned by Mr.
Kirby as having a black scutellum is probably the male.

In Hampshire this bee is very abundant at the middle and
end of August, on sandy and gravelly districts covered with
the Calluna vulgaris and other heaths, as Parley Common
and Ramsdown near Heron Court. Mr. Samouelle once met
with it in a sand-pit near Bexley, Kent, in July, where Mr.
Johnson has lately taken it ; Mr. Dale has captured it the
beginning of August at Blackgang Chine; and Mr. Kirby
found it, " but by no means common, in the autumn of two
succeeding years, 1797 and 1798, flying about sunny banks;"
and he adds, " since then I have not met with it."

The pretty Ophrys muscifera or myodes (Fly Ophrys) was
communicated by N. B. Ward, Esq.

This extensive genus of bees is remarkable for the wasp-like
appearance of the species, as well as for an odour which they
emit like honey and otto of roses. Many of them are very
common, yet nothing is known I believe of their ceconomy :
they are frequently seen coming out of holes in warm sandy
banks, and Dr. Leach supposed them to be parasitical.

In the Author's and other Cabinets.

This Genus, which approaches nearest to Epeolus, is distin-
guished from it by the long pubescence with which the head,
thorax, and base of the abdomen are clothed ; and upon an
examination of the trophi, by the remarkable long and bristly
laciniae or lobes at the base of the tongue, and also by its long
and 5-jointed maxillary palpi (described by Latreille and
Leach as 6-jointed).

The pretty species figured is the only one of the genus
found in Britain, where it is universally distributed, being
plentiful in South Wales, and at Hampstead in the neighbour-
hood of London ; Mr. Kirby has found it near Ipswich, and I
have met with it occasionally in Suffolk from March to June.
In April I have frequently observed its head of a bright orange
colour, from its being covered with the pollen, I suspect, of
Ulex Enropceus, as I have seen it early in the morning tra-
versing sunny banks where the Furze was in flower.

Our bee is fond of dry banks and sandy situations ; but we
know nothing satisfactory respecting its economy. Mr. Kirby
more than 20 years back had reason to believe that it depo-
sited its eggs in the cells of Anthophora retusa ; and Dr. Leach
also supposed it to be a parasite ; but we have heard of nothing
since either to confirm or disturb these opinions.

The plant figured is Glechoma hederacea (Ground Ivy).

In the Cabinets of the Brit. Mus.t Mr. Haworth, and Mr. Hanson.

A. HAWORTHANA was first described by Mr. Kirby from a
specimen taken by the gentleman whose name it bears, in Ash-
down Forest, Sussex, he believes : and about the same time
Major General Davies captured one in a wood near Charlton
in Kent. The male here represented was found in Epping
Forest the first week in June, and for the loan of it I am in-
debted to Mr. S. Hanson. The female is unknown. Our other
species I shall describe.

pi. 434. — pilipes Pz. 55. 8. — Hispanica Pz. 55. 6. Harris, pi. 40. f. 14.
Male rather more robust than A. Haworlhana, thickly and minutely
punctured and clothed with fulvous or yellowish hairs, more or less black
at the apex of the abdomen : labrum, face, and underside of basal joint of
antennas yellow, the first margined with black, with two black spots at the
base, the second with two oblique black lines approaching the insertion
of the antennas: mandibles sometimes with a yellow spot at the base:
wings pale yellowish fuscous, nervures piceous : legs variegated with black
and silvery pubescence and hair; spines of tibiae black: tarsi, middle, and
posterior ferruginous or piceous, the basal and apical joints black, all the
joints of the former plumose, producing very long hairs (fig. 8* ; b, the thigh ;
c, the tibia; d, the tarsus) : claws ferruginous at the base. Female black,
very pilose; labrum, middle and posterior tibiae externally, and the basal
joint of the tarsi entirely clothed with bright ferruginous hairs.

This species builds its nest in banks and old walls, and is
seen flying about sunny and sandy banks in March, April,
May, and the beginning of June : the male in its flight very
much resembles a Helophilus. " When I first set out in my
entomological career," says Mr. Kirby, " I began to notice
the motions of this Apis, and have continued to do so occa-
sionally ever since. Early in the spring the male may gene-
rally be seen attendant upon his swarthy bride, fluttering round
her, or hovering over her, while she with great coolness col-
lects the honey from flower to flower, without bestowing any
attention upon him ; if she departs he departs, and if she re-
turns he returns likewise. During the season of courtship,
his whole employment seems to be to attend upon her; but
when the halcyon days of love are over, like many other hus-
bands, he goes about his business, and leaves her to take her
flights in solitude."

Mr. Mathews, who is now engaged in collecting subjects of
natural history in South America, found a nest of this insect
in a wall at Chiswick, where they destroyed the grapes in the
garden in September; and having caught a male and confined
it in an open box, he was enabled to take many specimens of
the female, which came and settled there. This led him to
think the Jirst was a female ; he also observed a considerable
number of Melecta punctata [pi. 125.) entering and coming out
of this nest as if they lived together, which renders Mr. Kirby's
supposition very probable that they deposit their eggs in the
nest of A. retusa.

The plant is Aha cristata (Crested Hair-grass), communi-
cated by Professor Henslovv.

Neaklv related as this genus is to Anthophora (pi. 357),
there are most important differences in their trophi, antenna?,
and legs; but the easiest means of distinguishing them will be
by examining the 3rd joint of the antennae, which is shorter
than the first in Saropoda.

The 31st of July I observed the females at the back of the
Isle of Wight, flying about and alighting upon the plant
figured in the plate: they made a loud and shrill buzzing with
their short wings. On the 15th of August I found a male
and many females sleeping in the same flowers, it having
rained several days previously. A few days before I saw both
sexes flying over barren and heathy places and entering their
burrows.

Four of the Bombi were formed into a subdivision by Mr.
Kirby in his Monograph, and they have been lately designated
as the genus Psithyrus, which I think might as well have been
called Bremus, a name given to the Bombi by Jurine.

The males are distinguished from the Bombi by the nearly
equal breadth of the posterior tibia?, which are externally con-
vex and thickly clothed with hairs, whereas in Bombus they
increase from the base to the apex, are slightly concave ex-
ternally at the centre, and have only scattered hairs ; the
females are still more strongly marked, having in addition to
the above characters, a trigonate labrum and mandibles not
toothed.

The Humble-bees comprise a fine group of insects in this
country, readily distinguished by their hairy and handsome
clothing. In the first fine days of spring, or even earlier, the
females, which I believe hybernate, are attracted by the blos-
soms of the Willows to collect honey and pollen ; the neuters
appear later in the season, but the males are not common till
the autumn, when, as Mr. Kirby observes, " the thistles are
in bloom, upon the flowers of which they are abundant, some-
times seemingly asleep, or torpid, at others acting as if intoxi-
cated with the sweets they have been imbibing."

Humble-bees build their nests in the roots of trees or
amongst rubbish of bricks and stones ; they may be constantly
seen in the summer collecting moss for the purpose of cover-
ing their nests, which are sometimes lined with wax. The
comb is irregular, and formed of oval cocoons made of a kind
of silk daubed with wax ; they vary greatly in number, some-
times amounting to sixty, and are adapted in size to the three
sexes. Want of space compels me to refer the reader to the
6th vol. of Reaumur, and to Kirby's Monograph, for admi-
rable accounts of this interesting tribe.

Perhaps no genus presents more difficulties in determining
the species than Bombus; there are males, females, and neu-
ters of two sizes, and the hairs with which they are clothed
vary in colour with age ; it is therefore only by examining their
nests that the species can be ascertained, and perhaps not then
with constant or unerring success. I have some suspicion
that there are hybrids, and my friend Mr. Lyell took a female
of B. subinterruptus or terrestris, and two specimens of B. syl-
varum or Burrellanus out of the same nest in Scotland, and I
have specimens of the second and third of these insects, which
were captured together.

One species was added to this genus in my Guide, and since
then three others have been discovered.

12a. B. Hypnorum Linn. — Panz. 7.12.

A. Mei.lifica Linn. — mellifera Fourc. — cerifera Scop. — gre-
garia Geoff. — doniestica Ray.

Piceous, clothed with fine silky oehreous hairs : antenna; black : wings
yellowish, nervures ferruginous. Male the darkest, thorax and 2nd
joint of abdomen velvety, the space between them filled up with oehreous
down, margins of segments pale; 2 apical joints clothed with longish pi-
ceous hairs: tarsi ferruginous, excepting outside of basal joints. Neuter:
thorax hairy, hinder tibiae as well as tarsi ferruginous internally, light
brown outside. Female : second abdominal segment with 2 large rufous
patches at the base : hinder legs deep and bright oehreous.
Our figures represent the male, neuter, and female somewhat
larger than life, but their relative proportions are preserved :
the comb was one foot in length. I consider myself fortunate in
being able to introduce into my plate the nest of some Hive-
bees, which was discovered by Lord Malmesbury in his planta-
tions, near the river Avon, not far from Sopley. I had the
gratification of seeing it before it was removed in October
1838 ; it was attached to the arm of a tree, and hung down, as
represented in the plate, about 2 feet from the ground : a con-
siderable number of the bees had died with their heads in the
cells. Combs have been rarely found in hollow trees in this
country, "but one formed on the outside is I believe without a
parallel in the history of bees.

It would not be possible for me to condense into my limited
space the valuable remarks that have resulted from the ob-
servations of Swammerdam, Reaumur, Huber, Wildman and
Kirby, I must therefore content myself with referring to their
works, and to Dr. Bevan's " History of the Honey-Bee," for
accounts of the wonderful ceconomy of these little animals ; I
shall however transcribe a few remarks from the Mag. of Zool.

It is more than probable (says Dr. Bevan) that the life of the working
bee does not exceed 6 or 7 months. A good family of bees consists of from
12 to 20,000, and a fertile queen breeds that number every year, but they
all die annually except about 3000, which are supposed to be the summer
and autumn hatched ones. In the 1st week of July the young workers be-
gin to issue from their cells, and continue to do so for nearly 3 weeks : on
the 13th July was the first issue of drones, which continued to come forth
till the 25th ; these, if not killed by the neuters, begin to die naturally the
end of October till the middle of November, so that the life of the drone is
about 4 months ; the queen has been traced from hive to hive through a pe-
riod of nearly 4 years, so that she sees many generations pass away.

I may add that in the early days of April the workers awake
from their slumbers, and resort to the catkins of the willows to
replenish their stores ; the males appear later, and amount to
about 1500.

With the bee I have now concluded my task, and I trust the
materials collected have been selected to the taste and advantage
of those who have taken an interest in my Hive. I have to
thank my friends who have so handsomely protected it against
the attacks of enemies, as well as those whose valuable mate-
rials have been so kindly contributed during sixteen years to
its support. After a little rest I hope to resume my labours,*
and 1 trust the contents of a future hive may prove as accept-
able to the public as the present one.

In the Cabinets of Mr. Dale and the Author.

The Corduliae are distinguished by their uniform metallic
colour; they are separated from Libellula, to which they are
most allied, by the angulated anal margin of the inferior

wings, and from all the other Dragon-flies by the small central
lobe of the labium, as well as by the vesicle on the crown of
the head.

The species of Cordulia are the following :

1. metallica Vand. Lind. Mon. 18. J 3. — Schcef. Icon. tab. 113.
/ 4. ? .—Boesel 2. Aq. II. tab. 5.f. 2. <J .—Harris Expos,
tab. 27./. 2. ? .

Brassy-green, abdomen thickened in the middle, all the anal
appendages in the male simple, acuminated ; wings lutescent,
stigma yellow.

This species is admitted as British on the authority of Van-
der Linden, who quotes Harris's figure as the male, but it is
the female he has represented.

2. aenea Linn. — Schcef. tab. 167- f. 4. ? . tab. \S2.f. 1. ^. — Sow.
Brit. Mis. tab. 47. c$.—Do?i. 12. 415. <?.

Brassy green, abdomen thickened towards the apex, inferior
anal appendages furcate in the male ; stigma black ; labium
and spots on the underside of 2 or 3 of the basal abdominal
segments ochreous.

This species has been taken from the end of May to July
atWinandermere; nearWisbeach; in Starston and Costessey
Woods, Norfolk; Martlesham Heath, Suffolk; Woodford; Ep-
ping Forest; Hampstead; near Beaulieu, Brockenhurst; and
Pennington Commons, Hants. I have generally found it in
plantations where there are fir-trees, in such situations as Ca-
lepteryx frequents.

3. Curtisii Dale. — Curt. Brit. Ent. pi. 616. ? .
Male glossy green, with ochreous pubescence ; face bright
green ; base of the labrum and the labium ochreous ; eyes
pale pea-green, with a purple transverse stripe ; back of the
thorax ochreous, marked with black; abdomen compressed,
with a line of yellow spots down the back, decreasing in
length, forming 2 connected oval spots on each segment,
the basal one being the largest, 7th and 8th segments with
a pale margin only ; wings of a very pale yellowish tint, with
a small space at the base bright ferruginous ; stigma, ner-
vures and legs dark piceous ; anterior thighs ochreous in-
side at the base. Female with ferruginous-yellow wings,
softened into pale brown towards the posterior margin.
This fine species, which is unknown upon the Continent,
was discovered by Mr. Dale on Parley Heath the 29th June,
1820, and subsequently at Hurne in Dorsetshire as late as
the 16th July. On the 8th June, 1831, I captured a specimen
on the side of Ramsdown near Heron Court, in company with
Mr. Dale, who soon after described it in Loudon's Magazine
under its present name. I understand it has also been taken
on Braunton Burrows, Devon, by Mr. Cocks.

The plant is 'Luzula (Juncus) campestris, Field Rush.

stigma fuscous-ochre. Female : abdomen aeneous, 3 basal and
2 apical joints rufous. Var. bright ferruginous, ochreous be-
neath ; crown of head, clypeus, disc of collar, a broad line
down the thorax and a fine one on each side purplish-black ;

of the 3rd, on which there is a broken dorsal line of 4 black
spots and a ring; base of all the other segments with an ochreous
ring interrupted at the centre : nervures sometimes reddish : a
black dot at the apex of the thighs, a streak outside the tibiae
and tips of tarsi and of claws black.

These elegant and beautiful insects, which are distinguished
from cognate genera by their rliomboidal stigma, are abun-
dant in June and July in marshes, the sides of rivers, ponds,
ditches, hedges, &c, where they fly about sedges, reeds,
rushes, and other aquatic plants, on which they often settle.
The French have given them the trivial name of Demoiselle,
but with us they bear the formidableappellation of Dragon-flies,
which they in some measure deserve, as, like the rest of the
Libellulidae, they feed upon other insects, both in the larva
and imago states. It will be seen by the following list, that
there are many species, the sexes of which not only differ,
but from some cause or other individuals vary so much in
colour, that it is a difficult task sometimes to determine to
which species a variety belongs, and 1 think it not improbable
that some of these may be hybrids. The caudal appendages
of the males vary so greatly, that Charpentier thinks they will
supply good specific characters.

rounded at the apex (4). Palpi larger, triarticulate ? basal joint
large, 2nd and 3rd small subglobose (/>).

Mentum short, dilated anteriorly. Palpi} forming 2 large, fin-
like lobes (5).

Head rather broad and short : eyes large and remote in both sexes :
ocelli 3, forming a triangle in front of the head (l*o), remote, 2 very
large, the lower one smaller (I* front view of head). Thorax very
long and narrow , oval : scutel rather small and gibbose. Abdomen
long and sublinear, the apex furnished with 3 very long slender fila-
ments, composed of numerous joints (7 f), the central one a little

lobes, the others with one large lobe and one claw, notched at the
apex (f, a hind leg).

Metamorphoses quadruple. Larvae with 6 feet, 12 lateral lobes, and
3 setaceous ciliated tails. Pseudimago similar in form to the per-
fect insect.

Cognata Step. — Curt. Guide, Gen. 734. 2.

Head and thorax piceous, with several yellow spots on the
latter, formed by membrane ; sides of the collar orange, with 2
yellow stripes behind them : abdomen ochreous, with a dark
waved line down each side, and 2 long piceous spots on each
of the 2 or 3 terminal segments, the edges of all yellowish-
white : wings transparent, stained greenish-yellow, with 3
fuscous spots on the disc and 1 near the base ; nervures pi-
ceous : legs yellowish, all the articulations witli piceous spots
at the apex.

The Ephemerae are the true May-flies of anglers, no less
celebrated as a bait for trout, than they are for the shortness
of their lives; yet short as the natural term of their existence
is, myriads are swept away and devoured by the rising fish
before they have escaped from the water which gave them
birth. The importance of these insects in the ceconomy of
nature is manifest by the immense quantities that are pro-
duced, and without them many species of fishes would become
extinct. The multitudes of eggs that are deposited by the E.
vulgata must be incalculable, for a very small proportion only
of the whole can be hatched ; then the larvae living at the bot-
tom of the water become a ground bait for fishes, and the prey
of predaceous insects in all their stages. The pupa, if it be per-
mitted to rise to the surface, must there remain until the fly
in its first winged state or Pseud-imago, has time to burst from
its shroud, when its soft and heavy wings render its progress
to the shore slow and uncertain ; there it alights on a blade of
grass or some plant, and casts off its skin again, as related in
folio 484, and then it becomes the beautiful fly, which notwith*
standing the myriads that have been destroyed, we still see in
myriads undulating over l'ivers and their banks, in the morn-
ings and evenings of calm and fine days in the months of May
and June, again to contribute to the support of the finny
tribes.

I am convinced it would well reward any one living in the
Lake districts to study this family and the Phryganidae, for I
have never visited either Scotland or Ireland without finding
new and interesting species, especially of the latter order,
which swarms even on the steam-boats ; and the valuable and
talented memoir of Mons. Pictet proves what may be done
by steady attention to a subject in a favourable locality. In
North America, again, a vast and magnificent field must re-
main to be explored by some zealous and fortunate lover of
these tribes, it is to be hoped at no distant period.

Having obtained living specimens of the Ephemera, I was
able to detect some rudimentary trophi, which seem to com-
prise 2 large palpi with 2 lobes below them and a dilated la-
bium with 2 divaricating lobes. Imperfect as these oral organs
are, I think they are an additional proof of the affinity of the
perfect Ephemeridae with the Phryganidas, nearly related as
they are in their larva state to the Libellulidae.

I found both E. vulgata and cognata in the greatest profu-
sion on the banks of the river at Oxford the beginning of
June, and I am doubtful whether the latter is distinct. Our
figure represents the female a little larger than life ; the male
is much smaller and darker.

The plant is Callitriche aquatica, Star-grass.

Ro'esel (v. 2, tab. 12, f. 3 and 4) : Pseud-imago similar to the per-
fect insect.

Dispar Curt. Guide, Gen. 735. 2.

Pale castaneous, eyes and disc of thorax sometimes much darker
in the male ; segments of the abdomen with the margins brown,
filaments more than twice as long as the insect ; tibiae, except-
ing the anterior pair, ochreous towards the apex, tarsi fuscous :
wings transparent, superior pale yellow at the base in the male,
as well as the costal margin, which is pale brown towards the
apex, nervures of the same colour.

In the Cabinets of Mr. Dale and the Author.

The habits and ccconomy of the Baetes are similar to the
Ephemerae, from which they are distinguished by having only

1 filaments at the apex of the abdomen, and from Cloeon by
having 4- wings. They may be advantageously formed into
two sections : 1st, those with wings very much reticulated ;
2nd, having very few transverse nervures, and these have the
wings ciliated in the Pseud-imago.

Latreille and Leach describe the tarsi as 4-jointed, but
they are distinctly composed of 5 joints, and their singular
form as well as that of the claws is worthy of notice.

This probably is an extensive family, and for a list of the
species I must refer to the Guide, and for the descriptions of
some new ones to the Lond. and Edin. Phil. Mag.

As Linnaeus in his description of E. bioculata says nothing
of the number of the wings, it may not be a Baetis ; and as I
suspect his E. striata is the Pseud-imago of another species,
I have thought it better to adopt the one figured as the type.

B. dispar Curt. Brit. Ent. pi. 484-. S •

I have named this insect dispar from the little resemblance
that exists between the Pseud-imago and the perfect fly ; the
wings in the former have all the nervures suffused with fuscous
and the costa is not darker than the rest of the wing.

On the 4th of June I found the Pseud-imago on White-
thorns near Ambleside, and on the following day I saw the
operation of shooting its skin : the thorax swelled and first
burst through, then by drawing up its body, it kept forcing
itself out, and being exhausted it lay down for a short period,
having the appearance of a Nympha, it then turned upon its
back, began struggling, soon gained its legs and walked on to
the gauze that covered the top of the box.

The Plant figured is a species of Chara, new to Great
Britain, which differs from C. gracilis in its much smaller size
and in the denser and more tuft-like arrangement of the
branches. This addition to our Flora was pointed out to me
by Professor Henslow, in Bottisham-fen, during an excursion *,
and Professor Agardh, of Lund, who was present, pronounced
it to be his Nitella hyalina, the specific characters of which
we quote from his Systema Algarum: "Caule hyalino setaceo,
fructibus ad nodos in glomerulum congestis." This species,
from its great transparency and the comparative size of the
detached globules floating in the fluid contained in the stem,
is admirably calculated for exhibiting the circulation so con-
spicuous in this genus.

* This very agreeable excursion was proposed and conducted by Professor Hens-
low with his accustomed kindness and liberality: it took place after the Meeting
at Cambridge of the Association for the Advancement of Science, and I am happy
in this opportunity of recording the pleasant day I spent with him on that occasion.

Common and conspicuous as these insects are, nothing is
known of their metamorphoses; this is very remarkable, and
it leaves one to imagine that their early stages are passed under
ground. I cannot think the larvae are aquatic; it is more pro-

bable that they inhabit the trunks of trees like many other
Neuroptera.

The perfect insects are said to live upon Diptera, and the
two first species are found in woods, hedges, meadows, and
gardens, in May and June.

The rostrum is formed by the union of the elongated bases
of the trophi, and the singular structure of the tail in the males
has caused them to be called Scorpion flies.

As there are innumerable varieties of these insects, I think
it is very probable they may all belong to one species; I shall
however give the essential characters of the types found in
Britain.

The learned authors of the Introduction to Entomology have
most justly observed that " of all the Linnean Orders this
(Neuroptera) appears to consist of the most discordant tribes;
so that it seems next to impossible to construct a definition
that will include them all:" of the truth of which remark there
cannot be a more convincing proof than the genus before us,
when compared with the Libellulidae for example, or even the
Filicornes to which section it belongs, and the want of ocelli and
reticulated wings excludes it at present even from the family
in which it must be included, for the contour of the head and
the structure of the tropin prove beyond a doubt its affinity to
Panorpa, although the ovipositor with which the females are
furnished, is different to every thing we can recollect to have
seen in any of the Orders, unless it be that of the genus
Psylla; it is we apprehend, like the appendages of Blatta, em-
ployed for carrying the eggs as well as for depositing them,
for it has no oviduct, and the 2 valves open vertically instead
of laterally, as in Orthoptera and Hymenoptera. The man-
dibles it will be seen are serrated, and not bifid as described
by Panzer, and the stalks of the maxillae unite and form a base
for the mentum.

Dr. Leach first added this curious insect to our Fauna by
detecting a single specimen at Costessey in Norfolk in the
month of December ; and last November and January, Mr.
Henry and Mr. Francis Walker found 4- or 5 specimens se-
creted in the moss in a plantation at Southgate ; and it is to
their handsome contribution of specimens that I have the op-
portunity of presenting my readers with dissections and an ac-
count of this extraordinary genus. It is remarkable that all
the specimens hitherto taken in this country have been fe-
males, and I have not been able to find even a foreign speci-
men of the other sex in our cabinets, which I very much re-
gret ; they probably may appear earlier than November, and
may not reside in the moss as the females do. B. hyemalis
occurs in Sweden and Germany during the winter, and upon
the Alps amongst the snow.

These beautiful insects, with their splendid eyes and exquisite
gauze-like wings, are nearly allied to the Ant-Lions, and from
their preying in the larva state upon plant lice, they have been
termed by Reaumur the Aphis-Lion. The perfect insect is
short-lived, flies heavily and generally by night, and the scent
of it is very offensive.

There are few persons who have not been attracted by the
wonderfully brilliant eyes of these insects, which are, when
alive, like the head of a highly polished gold pin ; and their
green wings reflect the most lovely rose-colour and blue. The
larvae are very curious animals, and are well represented
in the 66th Plate of Sowerby's Brit. Mis., and also in the 3rd
vol. of Reaumur : they are most singularly formed, and their
appearance is rendered more grotesque by their bodies being
covered with the skins of their victims, the Aphides, on which
they live ; and by this means they render themselves almost
invisible amongst the Lichen on the trunks of trees where they
resort. Their eggs are not less worthy of notice, being pro-
tected from the attacks of parasitic and other insects by being
attached to the end of a long stiff filament, the base of which
is fastened to a leaf, as represented in our Plate.

The following species have been detected in Britain, ana
they are all found in June, July, and August.

1. fulvocephala Sain. — fulviceps Step. Considerably like the following in

colour, but the wings are longer, the nervures lighter, and the costa is

stigma brown ; legs pale testaceous.

3. reticulata Lea. — Schcef. Icon. tab. 5.f. 7 <y 8. — chrysops Linn. Green,

head and thorax spotted with black, sides of abdomen and most of the
transverse nervures of the wings black.

Always found in woods in June; New Forest, Coomb and
Darent-woods.

3b. ventralis Curt. Pale or yellowish green ; antennas fuscous at the apex,
with a black dot between the basal joints, another before each eye, 2
on the back and 2 on each side of the prothorax, and 2 between the
anterior wings ; underside of the abdomen piceous, except at the apex :
wings with short and pale pubescence, and a few of the nervures par-
tially piceous.

The Hemerobiadae are no less remarkable for their beautifully
reticulated wings and pedicled eggs, than for their singular
appearance and valuable qualities in the larva state, during
which period of their existence they live upon Aphides (plant-
lice), and in conjunction with the larvae of the Coccinellx
(lady-birds); and some of the Syrphidae are of the utmost im-
portance to the hop-grower, by assisting to free him from one
of his greatest enemies. Our readers will be much gratified
by consulting the 3rd volume of Reaumur, who gives figures
of the larvae, &c. on the 32nd plate, and the 1st volume of
Kirby and Spence, where their extraordinary habits are
amusingly related.

We have seen ten or twelve undescribed British species,
besides the following, which have been recorded by the authors
whose names are attached to them ; those which have been
noticed in the Entomologists Useful Compendium are preserved
in the British Museum.

1. H. phalaenoides Linn. — Panz. 87- 15. The only indige-

nous specimen I have seen of this fine insect, was
taken last June near Lanark, Scotland, by Mr. H.
Walker.

body, filiform, composed of numerous pubescent and submoni-
liform joints, from about 20 to 40 in number, basal joint the
stoutest, 2nd oblong, the following globose, gradually becoming
ovate towards the apex, the terminal joint being elongate-conic
(1, portions of the base and apex).

Labrum semicircular, slightly concave before, with 2 bristles
on each side (2).

Mandibles subtrigonate, apex acute with a notch on the inside
forming a rounded shoulder (3).

Maxillce small, terminated by 2 curved lobes, the inner one
linear and rigid, the other a little broader, more membranous
and rounded at the apex. Palpi rather long and porrected,
forming a kind of beak, and 5-jointed, first 4 joints nearly of
. equal length and stoutness, 1st oblong, 2nd 3rd and 4th obovate,
the two latter truncated obliquely, 5th long andsublanceolate (4).
Mention subquadrate. Palpi triarticulate, first two joints sub-

very ample and larger than the inferior, which are sometimes very
small; many longitudinal nervures and a few transverse ones, forming
3 discoidal cells in each (9). Legs, anterior the shortest, posterior
the longest : tibiae compressed, longer than the thighs, except in the
1st pair : tarsi short slender and 5-jointed, basal joint the longest,
snd and Zrd obtrigonate, 4th very short and bilobed, 5th very slender

Psociformis Holiday's Mss. — Curt. Guide, Gen. 14V. No. 2.

Length -3- of a Line, expansion 4 lines. Dead pearly white, an-
tennae twice as long as the body, composed of nearly 40 joints,
subochreous : superior wings very ample and distinctly irides-
cent ; inferior wings small.

In the Cabinets of Mr. Holiday and the Author.

This group may be distinguished from Psocus by the greater
number of joints in the antennae palpi and tarsi, by the pow-
dered wings (from whence the name of Coniopteryx) and the
absence of a stigma.

For the curious Larva represented at fig. L, I am indebted

to my friend Mr. Haliday, who says in his letter, "This larva
is found wandering in groves from the end of August to Oc-
tober; it is probably Aphidivorous, though this I have not
proved, nor have I bred it, but I can entertain no doubt that
it is the larva of C. tineiformis. The general character is
closely allied to the larva of Hemerobius, to which genus it
is related." It is rosy, with a large oval blackish patch on the
back, and large white spots down each side.

1. C. tineiformis Curt.

Length f of a line, expansion 2§.

Dead pearly grey, powdered : antennas not longer than the
body, containing about 25 joints; superior wings very ample
(9 s), inferior small (z), abdomen ochreous.

This insect is not uncommon in Norfolk and the New Fo-
rest, and I have found it abundant the end of June flying out
of a hedge in the day time in Mr. Dale's garden at Glanville's
Wootton. Mr. Haliday says, "It occurs in groves (especially
on Coniferag) in summer: the colour is clear bluish white,
but the dried specimens either fade or become rubbed. In
the living insect the palpi are porrected and adhere together,
forming a kind of beak. When captured they feign death,
with their antennae bent in under the thorax, as in Hemerobius
and Chrysopa."

2. C. Psociformis Hal— Curt. Brit. Ent. pi. 528 S ?

This Insect I also found in Norfolk many years since, and
Mr. Haliday took it in the same situation as the last: and
adds, " when the deflected upper wings in repose conceal the
lower, it resembles the former species, but it is distinguished
by its superior size and more brilliant white colour." The na-
tural size of the insect at rest is shown towards the lower
part of the Plate.

The Plant is Trifolium glomeratum (Round-headed Trefoil),
communicated by James Paget, Esq., one of the authors of a
" Sketch of the Natural History of Yarmouth," an invaluable
abstract of local information, and an admirable example, which
I hope to see followed in every County of the United King-
doms.

The genus Psocus bears considerable resemblance to the
Aphides, but the mandibulate mouth and the neuration of the
wings at once distinguish it, and as the disposition of the ner-
vures is sufficient to characterize two groups, I shall propose
the name of Ccecilius for the second.

The Psoci are found upon the bark of trees, paling, walls,
and under stones, and in all probability they and their larva;
iced upon the minute animals that live amongst the Lichen
and Mosses that grow in such situations.

RAPHIDIA OPHIOPSIS.

Order Neuroptera. 1' am. Raphidiadae Lai., Leach.

Type of the Genus R. Ophiopsis Linn.

Rapmidia Linn., Fab., Lat., «Src

Antenna inserted between the eyes, remote, as long as the

In the Author's and other Cabinets.

Dr. Leach has divided this extraordinary Genus into the
following species — 1. R. Londinensis, 2.qffinis, 3. maculicollis,
4. megacephala, and 5. Ophiopsis ; how far they may be good
species it is not easy to determine, as they are subject to great
variations, and the nervures of the wings are very inconstant,
frequently not agreeing in the same specimen.

R. LoJicli?ie?isisi as its name implies, is found in the vicinity
of our capital, even as near as Copenhagen Fields ; it has no
stigma. R. affinis is a smaller species, the male of which is
figured in Kirby and Spence's Introduction to Entomology
(pi. 3. f. 6.); R. maculicollis is very similar to R. Londinensis,
and R. megacephala and Ophiopsis appear to me to be the
same.

The larvae are described by Latreille as very nimble and
voracious, living upon small insects, and concealing themselves
in crevices in the bark of trees ; the pupae, like the rest of
the Order, have the power of locomotion. The perfect insect
also feeds upon smaller ones, its long moveable thorax
enabling it to seize its prey in any direction with great facility ;
and it is able to bite with considerable force with its acute
mandibles, which it can extend considerably.

The ovipositor is exceedingly dissimilar to those of any
other insects ; by Latreille's description and my own obser-
vations, it appears to be formed by two canals united, with a
space between, being composed of transverse rings which
enable the insect to propel the eggs to the apex, where they
are received and deposited by the two appendages, in clusters
like fly-blows.

The month of June appears to be the season for all the
species in the imago state, and they are stated to prefer the
neighbourhood of streams ; the specimen however figured in
the plate, with two or three others, were beat out of White-
thorns in rather high ground in the New Forest.

The plant figured is Veronica Chamacdrys (Wild Ger-
mander).

4. bicaudata Linn., Fab., Panz. 71.4.

The insects of the genus now under investigation, like many
others belonging to the same order, live in the water till they
assume their perfect state, when they form a principal portion
of the food of fishes, especially trouts, and are consequently
well known to the angler.

The following is a list of our British species.

A. Abdomens very robust.

1. P. grandis Nob.

2. marginata Fab. — Panz. 71. 3.—

flavipes Lat., Geoff". ?

B. Abdomens slender.

5. P. fuscipennis Nob. I 7. P. viridis Fab.— lutea Lat., Geoff". ?

6. media Nob. | 8. minor Nob.

P. grandis is half as large again as the species figured, and
has been taken I have understood near the Croydon Canal.

P. marginata. On the 4-th of June Mr. Dale and myself
found a few specimens of this insect upon a species of fern
near Ambleside, and a few days after I took a considerable
number, lying three and four together concealed amongst the
foliage of the plant figured, as well as others that grew close
to the water's edge, also the exuviae attached to a fern.

P. cephalotes. This species I found with the last ; and al-
though at first sight the two may be easily confounded, our in-
sect is distinguished by a much broader head ; the antennae
wings and setae in the males are not longer than the body, the
thorax is differently sculptured and transverse in the females,
and there are with very few exceptions two transverse nervures
on the disk of the inferior wings, which are always wanting
in P. marginata, the exuvia of the latter is beautifully macu-
lated, but in our insect it is entirely fuscous. The female
sometimes carries a globular bundle of little black shining eggs
at the apex of her abdomen. These two insects are a favourite
food of the trout in Cumberland, and are succeeded by the
Bracken-clock (Anomala horticola), and that again I believe
by the Willow-fly (P. viridis).

P. bicaudata is known by an orange stripe down the head and
thorax, and has been taken by Mr. Bracy Clark in Worcester-
shire, and in June upon Battersea bridge by Mr. Haworth.

P. fuscipennis, larger than P. viridis, with slightly fuscous
wings. This I took in Scotland.

P. media, the size of the last with yellowish wings and black
body, — beginning of June, on Oaks, &c, Ambleside.

P. viridis, smaller, thorax with a black margin, body pale
with a black stripe. Beginning of June, upon Alders, New
Forest. — Reaumur believes figures 8, 9 and 10, pi. 14, to be
the larvae and their cases of a small Perla (pi. 13. J] 12), which
is probably this or a congenerous species.

P. minor, like the last, but only half the size ; found near
Ambleside, the beginning of June, running about in pairs,
which proves they are not males of P. viridis.

Trollius europceus (Globe-flower) accompanies the insect.

I endeavoured to call the attention of Naturalists to this neg-
lected Order ten years since, when I described and illustrated
the genus Leptocerus (folio 57); and the hope I expressed in
a memoir published in the London and Edinburgh Phil. Mag.
the beginning of last year, has been realised by the appearance
of Mons. Pictet's admirable work on the Phryganidae. His
divisions, formed on the structure and ceconomy of the larvae,
supply the most natural and unexceptionable definitions for
Families, and the Genera he has characterized and adopted may
be considered the types of them. Averse as I am to multi-
plying genera, I am convinced that many more are already re-
quired in this order, and the number and situation of the spurs
in the tibiae, and the neuration of the wings, will furnish admi-
rable distinctions for such groups : the palpi I consider the
best test; but without dissection and a number of specimens it
is frequently impossible to obtain a view of them, or to ascer-
tain whether these Insects possess labial palpi at all.

The following are two of M. Pictet's analytical Tables, which
cannot fail to be acceptable to Entomologists.

The remarkable insect figured in our plate is most allied to
Limnephilus (pi. 488.), before which it may be placed. A
portion of the apex of the horns has evidently been broken off
whilst the insect was alive, as their length is unequal, and the
tips are of a darker colour. I have named it after my friend
C. J. Paget, Esq., who took it off some rushes in a salt marsh
between Yarmouth and Caister, the 14th of August 1833.

The Plant is Frankenia Icevis (Smooth Sea- Heath).

LIMNEPHILUS ELEGANS.
The elegant Grannom or May-fly.

Order Trichoptcra. Fam. Phryganidae.

Type of the Gems, Phryganea grisca Linn.

Limnefhilus Lea., Sam., Curt. — Phryganea Linn., Fab., Lat.

Antenna inserted close to the interior margin of the eyes, but
remote from the mouth, shorter than the wings, slender, seta-
ceous and pubescent, composed of numerous joints, the basal
one stout ovate and hairy, 2nd cup-shaped, 3rd oblong, longer
than the following, which are quadrate gradually becoming ob-
long towards the apex, the terminal joint elongate-conic (1).
Labrum (2) resting in a groove in the labium, tongue-shaped,
hairy, dilated, convex and orbicular at the base.
Mandibles very minute.

Maxilla small, terminated by an obcordate lobe, hairy on the
outside (4. m). Palpi shorter than the thorax, and 5-jointed,
pubescent and slightly pilose, basal joint short and oblong, the
remainder slightly attenuated, long and of equal length, except
the 4th, which is considerably shorter (4).
Mentum transverse, short, concave before, the anterior angles
ddated and rounded. Lip nutant, long, fleshy and conical. Palpi
attached to very short scapes, approximating at the base, triarti-
culate, 1st and 2nd joints hairy, of equal length, subovate, the
latter the slenderer, 3rd considerably longer, as broad as the 1st
and elliptical (5).
Head small, transverse : eyes lateral very prominent and globose :
ocelli 2, placed on the crown of the head near to the eyes. Thorax
small subglobose. Abdomen rather compressed in the male, longer
and stouter in the female. Wings, superior deflexed when at rest,
long and narrow, pubescent, and slightly coriaceous with numerous
longitudinal hairy nervures and an irregular line of transverse ones
beyond the middle with an elongated stigmatic cell (9) : inferior rather
shorter than the others but very ample, folded when at rest, very
delicate, with numerous longitudinal cells, many of them united by
transverse nervures. Legs, excepting the thighs, bristly : coxae long :
thighs slender : tibiae simple, posterior with a pair of spurs at and
another pair above the apex: tarsi 5-jointed, basal joint the longest:
slaws and pulvilli minute. Larvae inhabiting the water and living in
cases formed of sand, shells, pebbles, bits of wood, grass or straw and
leaves of plants; the head and 3 first segments horny, with 6 rather
long pectoral legs, 4th segment with 2 or 3 tubercles, the apical joint
furnished with 2 claws. Pupae formed in the same case.

Elegans Curt. Guide, Gen. 748. 17b.'

Palpi and antennae ferruginous; head and thorax somewhat
castaneous, the crown of the former and the back of the latter
lead colour ; abdomen ochreous, the back fuscous with whitish
margins to the segments. Wings shining, superior pale brown,
the nervures darker, with the 3rd cell, a stripe on the disc, the
1st, 2nd, 4th and 5th posterior cells and a spot at the base of
the 3rd and 6th whitish, the superior discoidal cell very long.

The female Phryganidee like the Ephemeridae produce their
eggs in double series : the larvae live upon those of aquatic
insects and the leaves of water plants : in this state the Limne-
phili form cases (from whence they are called Caddis or case-
worms) constructed of various materials, with a silken lining
impervious to the water and open at both ends ; but previous
to becoming pupee a grating is placed at each end to prevent
other animals from molesting and destroying them, and at the
same time for admitting the water. The larvae are furnished
with fleshy tubercles on the following segment to the pectoral
feet, which no doubt are to prevent them from being drawn
out of the case in the event of any resistance, as they walk along
in the water. There seems to be a state in the Phryganidae
somewhat analogous to that of the Ephemeridae, for at first
the pupa is quiescent, but when it is about to become an Imago
it cuts through the grating of the case before alluded to, rises
to the surface of the water, crawls upon some plant, the an-
tennas and legs being free, excepting the hinder pair, and there
it leaves the exuvia.

to the Phil. Mag., vol.4, and for a list of the whole to my Guide.

by fishermen for bait: in some parts of Holland they are so
abundant, as to be used for manure."

It appears from Roesel's figure that the larva of P. grandis
forms a case of the outside sheaths of the base of Reeds or
some such aquatic plants. DeGeer found the eggs in a double
mass of jelly deposited on Sallow leaves which hung over a
stream; and Mr. Hyndman of Belfast has seen the female
P. grandis enter the water for that purpose, which is so re-
markable a fact that I shall transcribe his remarks on the sub-
ject, which he was so obliging as to communicate to me.
" The Phryganea was taken at the Botanic Garden, Belfast,
the 27th May, 1S33. I first observed it on the leaf of an
aquatic plant, from which it crept down along the stem, under
the water, very nearly a foot deep. It then appeared to have
been disturbed by some Sticklebacks which approached it and
seemed inclined to attack it, and swam vigorously and rapidly
beneath the water over to some other plants. I then took the
insect up and found a large bundle of eggs of a green colour
closely enveloped in a strong jelly-like substance, attached to
the extremity of its abdomen. The bundle of eggs was of an
oblong form, bent in the middle, and the two ends attached
to the tail of the animal."

Polycentropus and Philopotamus Curt, — Hydropsyche Pictet.

Antenna inserted in front of the crown close to the eyes, a little
longer than the body, rather stout and attenuated, composed of
numerous pubescent joints, the basal one very short and thick,
2nd quadrate, 3rd and 4th oblong, the remainder becoming gra-
dually slender, longer and oval (1, a few basal joints).
Maxillary Palpi long, incurved, pilose and 5-jointed in both
sexes, 2 basal joints short, the latter very pilose, 3rd long and
stout, 4th rather shorter, subclavate and furnished with strong
bristles on the inside as well as the 3rd joint ; 5th slender, as
long as the others united, wrinkled, giving it the appearance of
being composed of numerous cup-shaped joints, the apex ovate
(4).

Mentum somewhat trilobed. Palpi considerably shorter than
the maxillary, pubescent, triarticulate, 2 basal joints very stout,
1st the shortest, somewhat obconic, 2nd truncated obliquely,
3rd longer than the other 2, but much slenderer, membranous,
a little dilated at the base and apparently composed of 12 or 13
joints, the apex ovate (5).
Head rather transverse ovate : eyes lateral and globose : ocelli undis-
covered. Thorax not broader than the head, and rather short. Ab-
domen short and narrow, the apex of the male furnished with 2 ovate
lobes beneath, and a process producing 2 divaricating appendages like
claws ; conical in the female. Wings deflexed in repose, superior
with 6 furcate terminal nervures and 4 or 5 transverse ones (9) :
inferior folded with 3 furcate marginal nervures. Legs, hinder pair
the longest : thighs, middle pair a little the longest : tibiae, anterior
short, with a spine on the side before the middle and 2 at the apex

pair near to the base (*) ; posterior pair very long and slender, with
two pair of long spurs, one at the apex and another considerably be-
low the middle (f); tarsi long slender and 5-jointed, intermediate a
little dilated and compressed, as well as the apex of the tibia, parti-
cularly in the females ; claws and pulvilli small.
Larva? living without a case : Pupae with a simple envelope. Pictet.

Irroratus. — Curt. Guide, Gen. 75 lb.

In the Author's Cabinet.

The present genus is a proof of the necessity of minutely in-
vestigating these curious insects, for although at first sight they
bear a strong resemblance to the true Philopotami, they are
considerably different in structure : there are no less than 22
spurs on the legs, and the terminal joint in all the palpi is
very remarkable : in the labial especially it has so much the

appearance of numerous cup-shaped joints that I am doubtful
whether they may not be membranous articulations.

It appears to me that I have three species of Polycentropi,
which 1 shall proceed to describe, observing that the first of
them may be the H.flavo-maculata of Mons. Pictet.

1. trimaculatusCW. Lond.fy Edin. Phil. Mag. v. 4, Genus 751,

No. 4.

Male. Expansion scarcely 6 lines. Fuscous with an ochreous
or coppery tinge : head clothed with pale shining hairs;
antennas annulated with the same colour; superior wings
with numerous ochreous round spots, most distinct to-
wards the margin, where they form a line, with 3 in
triangle at the posterior angle; legs dirty ochre.
The above name I applied to this species when I had only

a bad specimen, in which most of the spots, excepting the 3

above noticed, were obliterated.

I believe I found this insect twice in a ditch at Horning,

Norfolk, in June.

2. multiguttatus Curt. MSS.

Male, expansion 6, female 8 lines. Fuscous, iridescent : an-
tennae nearly as long as the superior wings in the male,
spotted or annulated with ochre; superior wings with in-
numerable ochreous spots, with a white dot on a fuscous
space on the interior margin, and an oblique line on the
disc ; posterior tibiae brown, especially the upper side in
the male.

The blacker colour of the upper wings and the hinder tibia?,
and the whitish transparent dot and line on the former, most
evident in the female, distinguish this from the former species.

It appeared in multitudes on the shores of Loch Fad in the
Isle of Bute the beginning of last August.

3. irroratus Curt. Brit. Ent. pi. 544 S •

Male, expansion 6f to 8 lines, female 9 lines. Brown, head
and thorax with shining yellowish hairs ; antennas annu-
lated with ochre; superior wings with numerous ochreous
silky spots, close together, but leaving several spaces,
forming 7 or 8 brown patches on the costa, disc, and in-
ferior margin; under wings very iridescent; legs dull
ochreous, with a pale castaneous tint.
The brown spots on the upper wings, most evident in the
males, distinguish this species from the others.

I took specimens the middle of last August in the Isle of
Arran, and the beginning of September I met with others on
large masses of rock in the bed of the river at Cartland Craigs,
a magnificent and highly picturesque ravine near Lanark,
which I visited with Mr. Haliday and Mr. H. Walker.

The Plant is Schcenus nigricans (Black Bog-rush), commu-
nicated by Jas. Paget, Esq.

neck clothed with griseous hairs ; margins of abdominal segments
pale : superior wings yellow-brown with a rosy hue, obscurely
freckled with ochre, nervures dark, with a small dark dot on the
costa at the apex of the first furcate nervure ; inferior wings
similar in colour but iridescent and less yellow ; legs fulvous ;
thighs fuscous and sometimes the tibiae.

As this group, which I gave as a section of Philopotamus in
the " Phil. Mag.", comprises the typical species of M. Pictet' s
genus Hydropsyche, I have adopted his name : it is nearly re-
lated to Philopotamus and Polycenlropus; but is distinguished
from the former by its much longer and slenderer antenna?,

as well as by the dilated tarsi of the female intermediate feet ;
from the latter by the absence of the central spur on the an-
terior tibiae; and from both those genera by the trifid nervure
in the inferior wings and differences in the palpi.
The following are British species :

1. instabilis Curt, in Phil. Mag. v. 4. — maculatus Don. v. 16.
pi. 54)8. 2. — atomaria Pict., Gmcl. ?

May, Southgate ; June, bushes and plants near the river,
Ambleside ; July, Glengariff ; several pair on the steam-boat
on Loch Derg and in Galway. As there is a P. maculatus Oliv.
it became necessary to change Donovan's name, and our insect
does riot quite agree with Gmelin's description.

2. hibernica Curt. Ochreous; antennae with slender rings to
the basal joints, head thorax and abdomen fuscous; superior
wings with a few small obscure spots at the base, below the
disc and round the apex and cilia: expanse 12 lines.

I took a male the end of July at Roundstone in Connemara ;
it is readily distinguished by its ochreous nervures.

3. pellucidula Curt. Phil. Mag. — lasta Pict. ? Head, thorax
and abdomen slate-black ; antennae very long, ochreous
spotted fuscous; wings semitransparent, superior obscurely
freckled with pale fuscous and ochre, margin spotted with
ochre from the stigma to the posterior angle, with 2 long
spots on the inferior margin and the legs ochreous: 14 to 15
lines. — Common in Perthshire in July.

4. lanceolata Curt. Phil. Mag. Wings fuscous, superior slightly
hooked, clothed with shining ochreous pubescence, slightly
freckled, the posterior margin spotted fuscous : 13 lines.

I took a male either in Scotland or near Ambleside.

5. angustipennis Curt. Phil. Mag. Antennae slightly serrated
and annulated ; head and thorax slate-black, abdomen red-
dish black ; wings fuscous, superior with an ochreous tint,
an ochreous oblong spot before, and a round one at the pos-
terior angle, very distinct in the males; legs ochreous, darker
at the base: 10 to 13 lines. — I have taken several in Norfolk.

6. fulvipes Curt. Brit. Ent. pi. 601 $ .

Taken by J. C. Dale, Esq., the end of June, off a hedge,
with a brook running below it, by Muller's Copse, near Glan-
ville's Wootton.

7. ventralis Curt. — angustata? Pict. Antennae shorter than
the wings, annulated; head and thorax griseous; abdo-
men slate-colour, beneath silky green or whitish ; wings
subdiaphanous fuscous, superior ochreous, with silky yel-
lowish pubescence and slightly iridescent, a large obscure
ochreous spot on the costa towards the apex, and another
on the interior margin beyond the middle: 6| lines.
This makes an approach in habit to the genus Tinodes. I

took both sexes in July on the steam-boat on Loch Derg.
The Plant is Charavulgaris var. /3 (Common Stonewort).

* The dissections are made I'rom Leptocerus ochraceus.

There are in the cabinets of this country about 130 native
species of the various genera forming the order Trichoptera
established by Mr. Kirby : of this number the greater portion
are unnamed and undescribed ; of those that have been noticed
bv authors, descriptions may be found in the works of Linnaeus,
Fabricius, and the 13th volume of Latreille's Histoire Natu-
relle.

Neglected as Trichoptera has been, it is difficult if not
dangerous at present to enter far upon the subject of species.
Dr. Leach divided the order into 12 genera, but no charac-
ters have been published of them even, excepting four, viz.
Leptocerus, Odontocerus, Phryganea, and Limnephilus.

Of the genus Leptocerus there are probably 20 British spe-
cies : the elegant one figured has been selected from its ap-
pearing to be a nondescript ; its rarity does not less entitle it
to illustration, for I have not observed it in any of the cabinets
of my friends : the specimens figured and described were
taken by myself resting upon the paling which surrounds the
Regent's Park, in the summer of 1 822 : the end of last August
I took 3 from off plants in a marshy situation near the sea,
upon the estate of Sir Thomas Gooch, bart., Benacre, Suffolk:
being certain that those which I took near town appeared
much earlier in the year, I suspected that they were another
species, but I cannot discover the slightest variation in them.

With the larvae and pupae we are unacquainted ; but little
doubt exists, from their being found in the neighbourhood of
streams or stagnant waters, that they are in their economy
like the rest of the family, the beauty of whose habitations as
well as the instinct displayed in the construction of them never
fail to excite our admiration. An investigation of their eco-
nomy would in all probability put us in possession of good
secondary generic characters : it would not be attended with
any difficulty to those who live in neighbourhoods where they
are found, for the cadis is well known and celebrated amongst
fishermen as a bait, and the case-worm may be met with
in every brook and pond; the subject could not but be
highly interesting to any one who loves to explore and study
the works of Nature. Whenever such materials can be ob-
tained as satisfactorily to identify the different stages of the
insect figured, I shall not fail to avail myself of the opportunity
of laying them before my readers.

The type of the genus (L. interruptus) is figured in Dono-
van's Brit. Ins. v. 16. t. 551. The plant figured, upon which
L. ochraceus was found in the autumn, is Epilobium hirsutum
(Large-flowered Willow-herb).

An ample series of fine specimens of Chimarra, which I found
in vast abundance in Ireland, enabled me to study its affinities ;

and it was my intention to place it in the 2nd edition of my
Guide next before Molanna, but by some accident it was in-
serted between Potomaria and Sericostoma, which in all pro-
bability belong to one genus. Although I still doubt if it be
better located than it was at first, when it was illustrated in
this work (fol. 561), I am anxious to correct the palpable error
committed in the Guide, before I proceed to discuss the affi-
nities of Molanna.

This type appears to have been unknown to M. Pictet at
the time his Memoir was printed ; we therefore know nothing
of its early ceconomy ; but from its being found in the neigh-
bourhood of deep water, it is no doubt similar to its allies.

It appears to me that its natural situation is between Lepto-
cerus and Odontocerus. The trophi are considerably like
those of the former genus, as well as the wings, and the long
stout antennae and the whole contour assimilate with those of
the latter group.

The way in which Molanna rests is peculiar, and bears a
striking resemblance at a little distance to the ochreous
Crambi : the antennae, palpi, and breast are pressed close to
the surface on which it stands, the wings are elevated and
somewhat cylindric, enveloping the abdomen, which is of
course concealed, and the legs are spread out: when thus
settled they are rather loath to move, especially the females.

M. angustata I find on paling near the water in the Regent's
Park : the males first come out the end of May ; the females
I do not find until the middle of June; and a few males ap-
pear again the beginning of August. I have never taken it
elsewhere, excepting a single male in a boat whilst I was fish-
ing last August at Henley. With them I find occasionally a
specimen with the palpi, head, and abdomen fuscous, which is
the M. nigrijpalpis of Stephens.

The plant is Acorus Calamus, Sweet Flag, specimens of
which were transmitted to me by Laurence Sulivan, Esq.,
and others from Wimbledon by J. E. Gray, Esq.

CHIMARRA MARGINATA.

Order Trichoptera. Fam. Psychomidae.

Type of the Genus, Phryganea marginata Linn.
Chimarra Leach., Curt.' — Psychomia ? Pictet. — Phryganea Linn.
Antenna inserted before the eyes, as long as the wings in the
male, shorter in the female, tapering, hairy, composed of nume-
rous oblong joints, basal one stout, subovate, 2nd the shortest, a
few of the following short, apical joint oval (1 the base and apex) .
Labrum minute and trigonate.

Maxilla closely united to the labium, with a pointed and bristly
terminal lobe. Palpi alike in both sexes, long, curved, com-
pressed, pubescent and 5-jointed, basal joint the broadest, cup-
shaped, 2nd and 3rd very long, the former stoutest at the base
and surrounded with long hairs at the apex, the latter narrowed
at the base, 4th short, subovate, truncated, 5th twice as long,
the slenderest and somewhat filiform (4).

Mentum suborbicular, truncated at the base, emarginate before.
Palpi not so long as the maxillary, hairy, triarticulate, basal
joint broad, somewhat oblong, 2nd a little shorter, elongate,
obtrigonate, 3rd nearly as long as the other two, slender and
filiform (5).

large, forming a spacious triangle. Thorax rather ovate. Abdo-
men rather short, especially in the male. Wings hairy, slightly de-
flexed when at rest, the superior crossing, the back flattened ; inferior
not folded; superior with 8 or 9 longitudinal nervures, 3 of them
forked; transverse nervures none (9). Legs, anterior the shortest ;
thighs, anterior the broadest but narrow at the apex, intermediate
the longest : tibiae, anterior simple (8), the others spurred at the
apex, the intermediate having a pair above (*), and the hinder tibia
which are the longest a pair below the middle (f) : tarsi 5-jointed,
intermediate compressed and a little dilated in the female ; basal joint
the longest, 4th small : claws of anterior feet rather long, the others
minute.

Marginata Linn.} — Curt. Guide, Gen. 752. 1.

Smoky black ; basal joint of antennae, face and head, excepting
the crown, clothed with orange hairs ; superior wings margined
with yellow-ochre, the marginal cell being of that colour form-
ing the broadest portion, the cilia the narrowest ; an oblique
nervure furcate at the apex, yellow- ochre, as well as another
beneath it towards the base, inferior wings with the costa ex-
cept at the base and the cilia at the apex of the same colour :
legs ochreous, base of thighs and anterior tarsi at the apex,
fuscous.

In the Author's and other Cabinets.

This highly interesting insect has been described by Linnaeus,
but it has never been figured, and M. Pictet does not appear
to have been acquainted with it; and although Dr. Leach gave
it a generic name, it has never yet been characterized. There
is no specimen contained in the Linnaean Cabinet, and from the
size mentioned in the Systema Naturae it appears to have been
the male that Linnaeus described, which is much smaller than
the female, being only 6 instead of 8 or 9 lines in expanse.

Chimarra is probably nearly allied to Hydroptila, but with-
out recent specimens it would not be safe to discuss its affi-
nities : those which I possess being much injured I cannot
vouch for the correctness of the form in the mentum, and the
labium also was too mutilated for description : I suspect that
the long hairs represented on the inferior basal nervure in
fig. 9. may be the cilia of the inferior wings transferred by
damp and pressure.

My friend Mr. Dale first gave me a specimen of this insect,
which he took on the Dart near Spitchwick, Devon ; the Rev.
W. L. P. Garnons met with it in plenty near Ambleside, and
at Capel Cerig, Wales, the 11th of June 1S32. I am also in-
debted to Dr. Stephenson for specimens, accompanied with the
following memorandum : " On the 7th of last June I took this
insect in abundance on dry stones in a small mountain stream
close by Rydal Hall, Westmoreland, the beautiful seat of Lady
Ann le Fleming."

I have much satisfaction in adding a figure of the local
Eriocaulon septangulare (Join ted Pipewort). One of my objects
in visiting the Isle of Skye last summer was to see this curious
plant growing, and I am happy in the opportunity it affords
me of acknowledging the many kindnesses we received from
Colin Elder, Esq., of Isleonsay, who directed us to the little
Loch where it was in flower, and pointed out to me the variety
with ten angles on the stalk.

In a tour through the south-west of Ireland last July, Mr.
Haliday and myself observed the Eriocaulon in abundance, in
various lakes from near Oughterard to Roundstone in Con-
nemara.

broad upright scales towards the apex, which is very acute.
In the Cabinet of Mr. Dale.

If Trichoptera be related to Neuroptera on the one hand, it
most certainly is as nearly allied to the Lepidoptera on the
other: it would therefore be impossible to join it to either
without uniting the three Orders. In the present instance, so
near an approach does Acentropus make to the Lepidoptera,
that if the palpi were broken off, it would not be easy to de-

cide to which Order it belonged, whether to the Trichoptera
or Lepidoptera. The mealy texture of the insect might induce
an opinion that it was Trichopterous, whilst the contour and
neuration of the wings would be in favour of its relation to the
Lepidoptera. The absence of a proboscis proves nothing,
since it is sometimes wanting in the Bombycidaj and other
groups. I do not, however, remember any instance amongst
the Lepidoptera in which the maxillary palpi are strongly
developed, and the labial absent ; yet such appears to be the
case in Acentropus: and amongst the Trichoptera, if there
be no other instance in which the labial palpi are wanting (but
I believe there is), at any rate they are frequently, if not always,
smaller than the others, as in Limnephilus (PI. 488.) and Lepto-
cerus (PI. 57.). From recent investigations of this Order, the
results of which have been published in the 4th volume of the
London and Edinburgh Philosophical Magazine, I have ascer-
tained that this character is not only general but much stronger
in many of the groups than in those above referred to. I lay
more stress upon this observation, as it appears to be an im-
portant definition in separating the Trichoptera from the Le-
pidoptera, since the characters hitherto given do not seem to
be sufficient to distinguish them *.

The generic name of this curious insect alludes to the ab-
sence of spurs at the apex of the tibiae ; the species, I have the
pleasure of naming after the Rev. W. L. P. Garnons, of Sid-
ney Sussex College, Cambridge, who took it at Layer Mur-
ney, near Colchester, Essex, and presented it to J. C. Dale,
Esq., to whom I am indebted for the opportunity of illustrating
this remarkable genus. I think I have heard of Dr. Leach
taking a specimen in June, in Scotland, and that it has been
found also on the Croydon Canal, and in Berkshire.

The Plant is Myriophyllum verticillatum (Whorled Milfoil);
communicated by Professor Henslow, from Bottisham Fen,
Cambridgeshire.

* The want of some such guide, it is to be presumed, has led Mr. New-
man to place Psyche (PI. 332,), a genus of Moths, in his Neuropterous
Circle, to elucidate the affinity between that Order and the Lepidoptera.
