I pause and ponder here.—Like you, mankind
Are born, frail insect! ignorant and blind ;
Man’s mind—his heart, in dust and darkness furl’d,
His bright soul’s clouded by a wintry world.
But when this dream of life hath pass’d away—

' Accorptne to the classification of the celebrated
Latreille, the Papilionaceous, or Lepidopterous in-
‘sects are comprehended in his Ninth Order, under
the title of LEprpoprERa.
ORDER LEPIDOPTERA, Linneus.
Lepidopterous insects have four membranaceous
wings, covered with a farina, composed of small
scales, and are provided with a trunk rolled ie in
a spiral form at the mouth.
| Trisz I.—DIURNA.
“Wings always free in repose, placed perpendicular
to the plane of position, and destitute of a bridle
or scaly bristle at the base of the lower wings ;
the antenne in many of the species terminated

in a small club or button, more or less conical
or triangular ; in others, slender and hooked at
tip.
The insects of this tribe fly and feed by day. The cater-
pillars have sixteen feet, and live on vegetables. The pupa)
are generally naked, or destitute of a cocoon, fixed to substances:
by the posterior extremity of the body, and in many by a silky
fillet, forming a kind of half ring at the upper part of the body,

With four wings, elevated perpendicularly in a state:
of repose ; the antenne having a club-shaped
termination, or almost filiform, without hooks at
the tip, with the exception of one genus, in
which they are setaceous and plumose in one 0
the sexes ; the legs are provided with one pair
spurs or spines.
Subdivision J. Third joint ‘of the labial palpi very small an
hardly perceptible, or very apparent, and furnished with
scales ; hooks at the end of the tarsi projecting ; caterpillar’
elongated, subcylindrical ; chrysalis of an angular shape.
Subdivision Il. Six feet, formed for walking, or nearly similar
in both sexes; chrysalis fixed by a silky band by its pos.
terior extremity, or inclosed in a thick cocoon ; central areola
of the lower wings posteriorly closed.
1. Hexapoda.
A. Internal margin of the lower wings concave.
The genera are Papitro, Parnasstus, and Twats.
B, Internal margin of the lower wings arched, and projecting
over the abdomen to form a canal.
The genera are Contras and Pigrts.
LEPIDOPTEROUS INSECTS. 13:
I. The two anterior feet shorter than the others, folded, not
_ ambulatory, in both sexes, or in the males only ; chrysalis
fixed by its posterior extremity, and suspended with the head
downwards ; central areola of the lower wings open poste-
riorly in many species.
A. The central areola of the lower wings is always posteriorly
closed ; the two anterior feet, although small and folded, very °
similar to the others; the lower wings in general scarcely
embracing the abdomen below ; labial palpi slightly elevated
above the hood, much separated, slender, cylindrical.
The genera are Danaus, Ipza, Heticontvus, and Acrza.
B. Central areola of the lower wings open in many species ;
two anterior feet often minute and concealed, or apparent
_ and very hairy; lower wings embracing the abdomen below ;
labial palpi rising above the hood, slender and cylindrical,
and not distant.
a. Central areola of the lower wings open posteriorly.
* The labial palpi are either separated through their whole
length, or merely at their extremity, and abruptly terminated
by a slender and a circular joint.
2. Perlata.
The genera are Cetsosia and ArGynnis.
** The inferior palpi are contiguous through all their extent,
and not terminated abruptly by a slender and acicular joint.

The genera are Pavonra, Brassotus, Evrisius, and ©
Satyruvs. :
In the Dutch work, De Wonderen Gods, we have
the following interesting information concerning the
transformations of the Alderman Butterfly, Am-_
miralis Atalanta of Rennie, by J. C. Sepp of Am-
sterdam :-—
“ Like all other butterflies, this species originates
from an egg, which, however, is very rarely met
with, because it is very small and green ; almost
indeed of the same colour as the stinging nettle,
(Urtica dioica,) on which it is laid by the mother
butterfly, and therefore easily overlooked.
* Although I had found, for many years succes—
sively, and in considerable numbers, the caterpillars
and the butterflies of this species, I was long un-
successful in procuring any of the eggs; but at last
I succeeded, having found one on the 6th of July, |
at the very moment the mother butterfly had laid it, -
and it hatched as well as any other of this class.
I found others afterwards, which had perhaps been
longer deposited, and they likewise hatched, and I
reared butterflies from them; so that now I know
their whole manner of life, and their several trans-
formations, and am enabled to detail these to the
reader from my own observation. |
« As soon as the infant caterpillar is hatched,
it begins to eat directly, and to look out for a place
LEPIDOPTEROUS INSECTS. 15
to live in. Providence has given it the faculty of
_ spinning certain threads ; and, after selecting a leaf,
it draws it together, by means of these, into a
roundish hollow form, leaving for the most part an
opening into the interior before and behind. The
leaf, when thus drawn together, serves as a house
} or tent for the little creature, and at the same time
furnishes it with food; and hence the longer it
lives in it the more perforated it becomes. When
} at length it has gnawed so much of the leaf as
renders it so full of holes that it becomes useless, the
caterpillar quits it, and goes to another leaf, pro-
ceeding in the same way as it did with the first.
Accordingly, when we are desirous of finding these
caterpillars, we must search for them on those
nettle leaves which are drawn together. I may
mention, however, that not more than one cater-
pillar will be found on a single leaf.
- © The circumstance of hiding within a folded leaf,
is not usual with every spiny caterpillar; and it
_ appears to me, that this species does so, more from
a peculiar liking to live solitary than from any fear
_ of danger, inasmuch as they are exposed to no more
danger or hardship than other spiny caterpillars,
which roam about freely and openly on the leaves.
This species, besides, is quite as hardy as the others,
with respect to enduring cold and heat ; and they
are as much persecuted by parasite flies, (Ichneu-
monidee,) which lay eggs in their bodies, as are
16 MODERN ARRANGEMENT OF
other spiny caterpillars; nor is their dwelling i
the folded leaf so securely constructed, as to prevent
the intrusion of such unwelcome visiters, a circum
stance always attended with a mortal result.”
Professor Rennie mentions a similar circumstance
He says, “‘ We happened to see a remarkable in.
stance of this last summer, (1828,) in the case
one of the Lilac caterpillars, which had changed
into a chrysalis within the closely folded leaf. A
small ichneumon, aware, it should seem, of the
very spot where the chrysalis lay within the leaf,
was seen boring through it with her ovipositor, and
introducing her eggs, through the punctures thus
made, into the body of the dormant insect. We
allowed her to lay all her eggs, about six in num-
ber, and then put the leaf under an inverted glass,
In a few days the eggs of the Cuckoo Fly were
hatched, the grubs devoured the lilae chrysalis, and
finally changed into pupe, in a case of yellow silk, |
and into perfect insects like their parent.” * _
« There must then,” continues M. Sepp, “ I
think, be some other reason for these caterpillars
hiding themselves in this manner, and I am in-
clined to believe it can be no other than their de-
sire to be solitary. In accordance with this view,
we find the eggs always laid singly and apart ;
and it is well known to naturalists, that all cater-
* Insect Architecture, p. 174,
LEPIDOPTEROUS INSECTS. 17
originating from eggs thus deposited are
solitary, as those originating from clustered eggs
re gregarious. The latter moreover remain in
company so long as they are in the caterpillar state,
while the former always occur dispersed, and lead a
solitary life. In this manner, then, the caterpillars
under notice live from the time they are hatched,
and even exhibit the same disposition when they
prepare for their change into the chrysalis state, as
shall afterwards see.
_ As to their manner of growth, such caterpillars
er widely from other animals which grow re-
jlarly in all their parts as they are supplied with
hment ; but our caterpillars, on the contrary,
w only in their inward parts, whose increase
puffs out the skin or outer covering that does not
grow, and hence becomes too small, so that at
length it must give way. In fact, it actually does
80, and this happens more than once during its life ;
a circumstance which I term the casting of the skin,
and which is thus performed: A few days before
he skin is cast, the caterpillar remains nearly sta.
ary in the same place, and leaves off eating.
= this period, the neck or hind part of the
head may be observed to swell, in consequence of
which the old skin becomes more stretched, the
inner skin is separated from the outer, and in some
smooth caterpillars the head may be decerned shi-
ning through. The old skin becomes gradually
feet. Afterwards, by repeated movements, the
caterpillar strips off the old skin altogether, and
appears in a new dress, which, as far as regards the
one under our notice, differs little from the old one
in colour and appearance. The head, however, is é
little larger, as are the spines and small hairs.
*« With respect to the latter, it is remarkable
that the new spines and hairs appear to have been
inserted in the old ones as in sheaths, from which
they are drawn out when the skin is cast. I infer
from this circumstance, that these spines and hai
are hollow, though in consequence of their minute-
ness, some of them being barely visible to the naked
eye, we cannot well demonstrate this otherwise
Who, I may ask, does not perceive in this wonder-
ful fact, the incomprehensible operations of an all-
powerful Creator! and where is the man who
could imitate these astonishing productions ?
“ Our caterpillar, after casting its skin and rest-
ing a little, begins again to eat the leaves of the’
nettle. I may mention, that all caterpillars do
not cast their skins the same number of times ; but:
with respect to the present ones, they cast their
skins four times, and as they grow quickly, the
castings closely follow each other, at due intervals
between. I have traced this in two of these cater-
LEPIDOPTEROUS INSECTS. 19
Willars, which were hatched from eggs the 12th of
uly, in the following order. Their first casting of the
ins occurred on the 14th, the second on the 17th,
tithe third on the 21st, and the fourth on the 26th.
They then continued to eat and grow till the 15th
of August, when, having completed their growth,
d reached their full age as caterpillars, they left
off eating, and prepared for entering upon their
}second stage of life, namely, that of chrysalis, which
has no resemblance to the caterpillar. This change
took place on the 17th of August.
__ “It hence appears, that the first stage of life, or
‘the caterpillar state of this insect, only lasts for five
omplete weeks ; but I must remark, that in rear-
ing the caterpillars for the purpose of observing their
changes, they must have fresh food every day, and
‘In a warm day twice, otherwise they will not
thrive. |
** The cover of the box where they are kept,
ought to have small holes in it for the admission of
fresh air ; or it may be covered with crape or gauze.
‘It ought not to be shallow ; for if so, the wings of
‘the butterfly, when it comes forth, may be bent or
‘injured.
_ “ We have thus seen our insect in its first stages
of life ; but it is destined to arrive at a higher stage
of existence, and is born to be admired, though it
does not reach this stage till it has undergone sick-
ness and suffering, with hardly any apparent sign

its trance, and appears full of animation; and
richly ornamented.” * ii

The insects of this genus are decorated with lively

sunset, flitting from flower to flower, sucking melliferous liquids
with their long proboscis. The caterpillars have sixteen feet,
their skin is smooth or ganulated, and without hairs. Almost
al of them have a kind of bent horn on the eleventh ring, the
use of which is not known. Among the caterpillars, that
which is found on the lilac and ligustrum is remarkable for the:
singularity of its attitude. It is generally fixed to a branch by
its membranous feet, with the body elevated perpendicularly
and the head inclined, in whieh position it remains for hours.
In this attitude it is conceived to resemble the figures of the
fabulous sphinx, hence the name of the genus.

he caterpillars have sixteen feet. They are smooth, slightly
iry, and have not, like those of the Sphinges, a horny appen-

almost all the rest of its tribe, has very long legs, and assumes
an attitude somewhat like that of the larva of the Puss Moth,
with its tail cocked up, and its head and feet erected in the

The caterpillars have generally sixteen feet, and they live
under cover, some in tubes, which they fabricate, and others, |
which have in consequence received the name of miners, in
galleries formed in the interior of leaves. The species which
destroy woollen cloths, furs, &c. inhabit portable tubes. The

The insects of this genus and its congeners are very destruc-
tive to woollen cloths and furs. Inclosed in a tube, composed
| of the materials in which they are found, the caterpillars per-
forate, eat, and digest these substances. At the commencement
of spring they change into pup, and remain in this form about
twenty days. After coupling, the female deposits her ova in
the substances upon which the young are afterwards to feed,
and the caterpillars are hatched in fifteen days after. Many
means have been proposed to prevent the ravages of these
small insects; but the most effectual is oil of turpentine. A
piece of cloth or paper saturated with this oil, and placed in
the trunks, closets, or wardrobes, to be protected from their
depredations, soon kills them. A solution of corrosive subli-
mate and spirit of wine is also found to be an effectual preven-

the slightest touch ; the lower wings are plicated longitudinally
on their internal side. They are commonly found in woods, gar-
dens, and meadows, about the plants where the females deposit
their ova. They fly abroad generally ahout sunset, remaining
‘during the day concealed under leaves, on branches, or fixed
]} upon walls. They couple almost as soon as they change from

Genus Puatana, Latreille.
The antenne are setaceous, short, simple, pecti..
nated or plumose in both sexes, or in the males
only ; tongue often small; lower palpi almost
concealing the upper, nearly cylindrical or conical,
short, and covered with small scales ; wings large,
extended horizontally, or slightly sloped, and
the posterior border in many species angular or
dentated.
This genus comprehends nearly that division of the Linnzan
_ genus Phalena termed Geometra. Almost all the caterpillars
are smooth, with a slender elongated body, and on the backs of
; many are eminences or warts resembling the knots or buds of a
small branch. They live solitarily, and feed on vegetables.
‘Some eat only the leaves of certain trees, while others feed in-
- discriminately on many. They walk by approximating the feet of
both extremities, and raising the intermediate portion of their
body into a ring or arch. Their progression is accomplished by
measured projections of their anterior feet, the posterior ones
being brought close up to the others at every step, the body
rising at same time into an arch. This mode of walking has
given rise to the application of the term Geometra, or measurers
"of land, by which the genus has been characterised. These ca-
terpillars are farther remarkable for the manner in which many
of them attach themselves to the branches of trees, and which
_ proves them to be possessed of muscular strength in a great de-
gree. Some fix their posterior feet on a small branch with the
body placed vertically, and remain immovable in this position
for hours, and others appear in attitudes which require the
exertion of still greater muscular power. When the leaf is
touched upon which one of these caterpillars is placed, it drops
off, but does not fall to the ground, having always a silken thread

of extreme tenuity; this it has the power of lengthening at
will, by which it swings itself to the ground, and ascends at
pleasure. The species destitute of posterior feet, suspend them-
selves by the extremity of the body like the caterpillars of some
butterflies. The time which the Phalene remain in the chry-.
salis form, varies in different species. A great number become
perfect insects towards the end of summer. These all perish
after having secured the reproduction of their ova; but those
which do not undergo their metamorphosis till autumn, conti-

THE antenne are elevated at the tip; the wings
are entire, sooty black, or brownish black, with a
white dot on the middle of the superior pair, and —
with rufous lunules on the inferior ones; margins
beneath white, with rufous dots ; the under surface
is of a pale brown, with numerous white eyelets, —
black in the centre. The male is lighter than the
female. The extent of the wings is from one inch
to an inch anda sixth. It appears in the winged
state at the end of July.
This insect was first discovered on Arthur Seat,
near Edinburgh, by Dr Leach, and also on the —
Pentland Hills, near Edinburgh, by the same
gentleman. Till that period, it was esteemed as
the highest possible rarity. It has also been found
at Dumfries and in Devonshire.
The Papilio Artaxerxes is by no means striking
in its appearance, but valuable on account of its
rarity.

The larva feeds on the ash-tree, the poplar, oak,
and elm ; and is found in Yorkshire, Kent, Suffolk,
and Surrey ; it changes to the pupa state in June.
The chrysalis is of a pale raw umber brown, and is
slightly covered with hairs. The perfect moth
emerges in July.
The English name given to this very beautiful
moth, was in consequence of its having been first
taken at Clifden in Buckinghamshire, in the month —
of July. It was discovered hanging against the
pedestal of a statue, having just emerged from the
chrysalis, and was in the act of drying its wings.
It is extremely probable that this elegant butter-
fly was originally introduced into Britain in the
egg or pupa condition, among continental plants.
It is one of the rarest, as well as the largest of
the British lepidoptera, and is much less uncommon —
in Germany, and other parts of the continent, than —
in Britain, /

Tuts pretty insect is of a fine lucid emerald
green, with two waves across the upper, and one
across the under wings. The wings extend one
inch and one-fourth, to five-twelfths.
Donovan says, “ This species we have ever found
peculiar to the woods about two or three miles be-
yond Dartford, in Kent, particularly on the skirts
of Darnwood, and near the banks of the river
Thames, at Queenhithe. It has probably never
been taken elsewhere, or the name Dartford Eme-
/rald would not have been so generally adopted by
collectors.
I am not certain whether in the larva state it
feeds on the convolvulus, although I found it on a
} plant of that kind, as its climbing stalks and tend-
{ rils were so intricated with branches of white thorns,
oak, and brooms, as to prelude any accurate deter-
} mination.”

The history of this little moth is very interest-
ing, and was given at considerable length by Mr
W. Curtis, author of the “ Flora Londinensis.”
In the year 17782, the inhabitants of London and.
its vicinity were thrown into the utmost consterna-
tion by the appearance of a phenomenon far from
usual in the northern regions of the earth,—a host
of insects, in numbers like the locusts of the deserts,

were observed at once to pervade the whole face of |
vegetation, and despoil the herbage in many places”
for miles, of every trace of verdure. These were no
other than the larve of an insignificant moth, the —
subject of our present plate. )
The ravages committed by this insect were
assuredly less considerable than the vulgar were
inclined to believe. True to their natural instinct, —
some particular vegetables were preferred to others, —
and these they devoured with impunity, while
others were only partially attacked, as though
eaten with reluctance in the general scarcity of
their natural food ; and again, others being still less”
‘palatable, entirely escaped their devastations. The
aspect of vegetation was nevertheless such as might —
justly create alarm: plants, hedges, nay, whole
plantations of fruit-trees, as well as trees of the
forest, shared in the general havoc, presenting their
leafless branches in the midst of summer, as though —
stricken and destroyed by the blasts of winter. An —
appearance so extraordinary was calculated to create”
terror: it was naturally interpreted as a visita-
tion from heaven, ordained to destroy all the sources ©
of vegetable life, to deprive men and cattle of their

: hawthorn, the elm, and fruit-trees ; the fodder for
the cattle, and the harvest for mankind, remained
untouched. The appearance of such a host of little
depredators, seems, however, to have afforded a
“seasonable admonition, evincing to an unthinking
multitude, how easy the comforts, nay, even the
existence of man, may be assailed by a creature so
insignificant, had not the limits of its ravages been
prescribed by Him “ who wills, and is obeyed ;”—
its intrusions certainly created alarm, but did little
serious injury.
_ This is no exaggerated picture of the public mind
on the occasion to which we refer; its alarm was
so powerful, and prevailed to such an extent, that
prayers were publicly offered up in the churches to
avert the calamity it was supposed they were in-
tended to produce. The webs containing the larvee
were collected in many places about the metro-
polis by order of the parish officers, who allowed a
certain prize to the poor for gathering them, and
‘superintended the burning of them in large heaps
‘with coal and fagots. At this precise period the
tract by Mr Curtis, as above related, appeared.
In this memoir the history, manners, and propen-
sities of this little creature were explained, and the
information it afforded must have undoubtedly con-
tributed in an essential manner to calm the terror
before excited. Its publication was useful in an-
other point of view; for by its means the pursuits

of the entomologist, then confessedly in a state
of infancy in this country, were looked upon with
more respect, and we have no doubt contributed in
an eminent degree to the advancement of the
science. ;

“ has of late been strongly excited by the unusual
appearance of infinite numbers of large white webs,
containing caterpillars, conspicuous on almost every
hedge, tree, and shrub, in the vicinity of the metro.
polis ; respecting which advertisements, paragraphs,
letters, &c., almost without number, have appeared
in the several newspapers, most of which, though
written with a good intention, have tended greatly
to alarm the minds of the people, especially the
weak and the timid. Some of these writers have
gone so far as to assert, that they were an usual
presage of the plague; others, that their numbers
were great enough to render the air pestilential,
and that they would mangle and destroy every
kind of vegetable, and starve the cattle in the fields.
From these alarming misrepresentations, almost
every one ignorant of their history has been under
dismal apprehensions concerning them.
«« Some idea may be formed of their numbers from. f
the following circumstances: — In many parishes _
about London subscriptions have been opened, and
the poor employed to cut off and collect the webs at
one shilling per bushel, which were burned under,

‘Wthe inspection of the churchwardens, overseers, or
‘headles of the parish ; at the first onset of this
‘}business, fourscore bushels, as I was most credibly
‘jinformed, were collected in one day in the parish of
apham.”
The Brown-tail Moth is found in many parts of
Zurope. ' Albin, who published in 1720, says the
caterpillars lay themselves up in webs all the winter,
and as soon as the buds open they come forth, and
‘devour them in such a manner, that whole trees,
and sometimes hedges, for a great way together,
e absolutely bare. Geoffroy describes it as the
entirely of their foliage in the spring. It is also
‘Jnoticed by Ray.
| These caterpillars have happily many enemies,
they are eagerly devoured by birds ; the ichneumon .
fly destroys them by myriads; and it is supposed
}that the absence of the latter, from some unknown
cause, might have contributed, for one or two sea-
}sons, to their immense increase. As soon as they
quit the egg they begin spinning the web, and,
Phaving formed a small one, they proceed to feed on
the foliage, by eating, like most other larvee, the
upper surface and fleshy part of the leaf. In these
webs they are progressively increased in size, as

punctated dots, from whence emanate short fasciculi
: of very fine hairs ; along each side is a longitudinal
yellow line; the belly is rusty brown, and the
feet are black. They are subject to considerable
variety of appearance, as they progress towards
maturity. When young, they are yellowish; the
tubercles black, with a stripe of the same colour
as the segments of the joints. After this, the
yellow bands become orange, and the transverse
black stripes appear interrupted with longitudinal
bands of pale green. Some are entirely green
except the tubercles, which are yellow, and a small
black speck on each joint ; and others are green,
chequered with black, and marked on the side
with a row of similar spots. In the winged state,
however, we find no permanent and characteristic
distinctions.
In the earlier state the caterpillars are grega-
rious.
The chrysalis is black, and very blunted in shape.
The conformity and likeness which prevails be-
tween the male and the female throughout the
greater part of the animal kingdom, cannot, how-
ever, in insects be depended on; the difference is
frequently such as to deceive even the most expert
entomologists. The difference between the male
and female Emperor Moth is strikingly obvious;
the male is smaller than the female, and the
colours in general darker ; the lower wings also are

nearly oval, and very deeply feathered or pecti-
nated, and those of the female also pectinated, but
so slightly as to appear setaceous. As the structure
of the antenne is an unerring criterion by which
the sexes are ascertained, the Phalena Pavonia
Minor is a phenomenon in entomology ; for both
the male and female so perfectly resemble the
female Emperor Moth, Phalena Pavonia Media,
that it may be mistaken for the same species; the
female differs in no respect from it, and the male
only in the form of the antenne.
Linneeus, and after him Fabricius, describes
three varieties of Phalena Pavonia. 1. Minor.
2. Media. 3. Major. The first is the variety
found in this country, and in the north of Europe. —
Weare informed by Latreille, that a manufactory
of silk from the cocoons of this caterpillar has been
established in Germany.
Albin says, that in a specimen which he pre-
served, the male seemed to have changed to the
aurelia state on the 16th July, and in March
following it emerged the perfect moth. But the
time of their appearance depends.on the pro-—
portion of heat or cold; Albin’s subject was pre-
served from the severity of winter in a warm room.
The usual time to find them in the caterpillar state
‘’

THE EMPEROR MOTH. 97
is in the month of August, and in the end of
April they transform into the perfect fly.
The Emperor Moth is not by any means rare in
Britain, and is to be found in Kent, Sussex, Nor-
folk, and Devonshire.
The singular provision which Rasare makes for
the protection of this moth, deserves particular
‘notice. When the time of its continuation in the
caterpillar state is expired, by much labour it
forms a kind of bag or purse-of a very tough sub-
s:ance. This it fixes against the trunks of trees,
&e., by a number of hairs or filaments, which re-
main on the external surface. It lines the outer
case by one of a firm texture, the top of which is
closed by several bristles that unite in the centre,
exactly representing a cap, and excludes almost the
possibility of its receiving an injury during this
defenceless state. In this bag it passes to the
aurelia state, and remains until it transforms the
perfect insect. .
Authors instance many plants as the food of the
Emperor Moth ; it will live on the rose, the elm,
alder, oak, the willow, and on thorns and brambles
particularly.

THE PUSS MOTH. 99
The caterpillar from which this moth is pro-
duced is solitary, and is of a very extraordinary
form, and has rather the appearance of a formid-
able or venomous creature than the larva of a
moth. It is of a bluish purple on the back, covered
with small black punctated dots. This back ap-
pears like a mantle in which the animal is invested ;
the sides and belly are of a rich green, and each
segment is provided with a small ovate rich yellow
dot ; the head is short and thick, dark burnt umber
brown ; it has two tails of crimson filaments at
the extremity of the body, and these can be pro-
truded or concealed within the base at the crea-
ture’s pleasure ; when protruded, they have a con-
tinual. writhing, vibratory motion; it feeds on
willows, sallows, and poplars, and is generally
found in great plenty where those trees grow, and
in the month of July.
The larva, when attacked, defends itself by
ejecting an acrid fluid from an opening in the under
part of the neck.
The pupa is brown, inclosed in a hard case. _
The Puss Moth passes to the pupa state in Au-
gust, in which condition it remains all the winter,
and appears in the winged state about the latter
end of May, or early in June following. It is found
near London, in Yorkshire, and Cambridgeshire.

are scarlet. There is a peculiarity in the upper
wings of this moth, in being considerably less than
the under ones. ,

ful moth, although it has none of the dazzling
colours for which many of its congeners are Se at
able. It inhabits China.

has furnished them with the greatest plenty
proper food, viz. during the months of Augu
September, and October. When the insect is pré
pared to make its eseape, and be changed to its p
fect state, it discharges from its mouth a large quan
tity of liquid, with which the upper end of the case
is so perfectly softened as to enable the moth to
its way out in a very short space of time ; an o
tion which is always performed during the “oe

wholly taken up in providing for a continuation of
the species, and do not exist more than from six
to twelve days when confined; how long they
may live when at liberty is hard to say, but ]
imagine nearly the same as when restrained.
While in this state of perfection, they receive no
nourishment whatever, nor have they any mouth
or channel by which food can be received. When
the female is impregnated, she deposits her eggs on
the branches of the tree she may be resting on, to
which they adhere firmly by means of the gluten
they are covered with when newly laid. ;

« The following interesting history of these m¢ nl
beautiful as well as most useful animals, I have he
the good fortune to procure, by means of Mr Willian
Pope of Mahometpore, and with the writer (M
Atkinson’s) permission, I transcribe in this place :—
‘I have an opportunity of consulting two Of
the hill people, in whose neighbourhood a good deal
of Tusseh silk is produced, and whom I have que
tioned on points imperfectly known to myself.
reply to the Doctor’s questions regularly :—
“1st. The cocoons of the insect, which fee¢
on the Byer leaf, are called by the natives Bughy,
producing a Tusseh silk. They are annual, and ¢
said to remain in the cocoon nine months, and t
be three months in the egg and worm state.
‘2d. This species cannot be domesticated.
am informed that the natives cannot even retai
any of it for seed. The hill people say that the
go into jungles, and under the Byer and Assee
trees they find the excrement of the insect; 0
which they examine the tree, and, on discoveri
the small worms, they cut off branches of the tre
sufficient for their purpose, with the young broo
on the branches; these they carry to convenien
situations near their houses, and distribute the

thereof, but they put none on the Byer tree.
e Parieahs, or hill people, guard the insects night
d day while in the worm state, to preserve them
om crows and other birds by day, and from bats
y night.
LEAF OF THE JUJUBE OR BYER TREE.
‘I myself have seen them thus watching the
rood. This species cannot be confined, for so soon
the moth pierces the cocoon it gets away ; and the
eople add, that it is impossible to wings it by any
recaution whatever,
120 THE TUSSEH SILKWORM MOTH,
‘ 3d. To wind off these cocoons, they put them
into a ley made of plantain ashes and water, fox
about two hours, after which they take them out
of the ley, and put them in their wet state into an
earthen pot ; those which are properly softened are
first applied to the reel, and so’ on, as the cocoons
become soft, for four or five days, till the whole a
wound off.’
‘ The implement used for taking off the an
is a small common reel of four bars. The cocoons
are laid in a smooth earthen dish, without water;
the reel is turned by the right hand, whilst the
thread of four or five cocoons passes over the left
thigh of the spinner, and he gives the thread
twist with his left hand uporhis thigh. The ope-
ration is this instant in my sight, with a thread
five cocoons, the produce of another species called
Jarroo, and described below, but the reeling is ex.
actly the same as that of the Bughy, and therefo
one description answers for both. I must add, that
- the thread is exceedingly apt to come off double an
treble for several yards together, which is not
garded by the natives, as breaking off double threa
would diminish the produce, and, moreover, woul
occasion loss of time : a very even thread, howeve
may with care be reeled from either the Bughy o
Jarroo cocoon. .
4th. ‘The Bughy silkworm feeds indifferently
on Byer and on Asseen leaves, and is a species:
THE TUSSEH SILKWORM MOTH. 121
every respect perfectly distinct from the insect of
the Palma Christi, the latter being different in size,
much less cultivated, and fed in houses as regularly
as the mulberry worm. I shall not proceed to de-
scribe it, as the species is not at all included in Dr
Roxburgh’s questions.
©The Jarroo cocoons alluded to above, are so
called from being produced in the coldest month of
the year, say January ; the Bughy being about a
month before them. The Jarroo are likewise an-
nual, and the history of them is nearly the same as
that of the Bughy ; they are however different, I
am assured. The Jarroo will eat the Byer leaf if
he cannot get the Asseen, but he will always pre-
fer the latter, and produce a better cocoon when fed
on it. His silk is more of a dull colour than that of
the Bughy, which latter worm the hill people put |
en the Asseen alone, not because it prefers it to the
Byer, but because they have greater plenty of As-
seen than Byer, and, moreover, trim and dress out
plots of Asseen on purpose for the worms. The
principal difference between the above two species
is, that the natives retain a part of the Jarroo co-
eoons for seed ; these they hang out on the Asseen
trees when the proper season of the moth arrives ;
when the moths come out, the male insects invari-
ably all fly away, but the females remain on the
trees. These are not impregnated by the males
bred along with them, but, in ten or twelve hours,

122 THE TUSSEH SILKWORM MOTH.
or perhaps one, two, or three days, a flight of males»
arrive, settle on the branches, and impregnate the:
females ; by the bye, the hill people calculate good
or ill fortune in proportion to the speedy or tardy”
arrival of the stranger males. These insects die as’
soon as the purposes of nature are effected, and the
females live only to produce the eggs on the branches
of the trees, and then expire. In regard to they
Bughy species, they all take flight, females as well’
as males, and hence the natives firmly believe that:
they are all males, though I cannot see any physical:
reason for supposing them so. I have frequently’
endeavoured to detain the males of the Jarroo spe~
cies, and have kept them locked up in a box for
that purpose ; but whether they did not like to
make free with their female relations, or from what
other cause I know not, but I could never obtain a
breed in the domestic state, and the efforts of the
male to escape were wonderful, and at last always
effectual. The accounts given by the natives
the distance to which the male insects fly are ve
astonishing. I have put, at different times an
occasions, innumerable questions to them on thi
subject, and they assure me that it is no uncommo
practice amongst them to catch some of the mal
moths, and put a mark on their wings previous
letting them fly, the marks of different districts be
ing known. Iam told that it has been thus ascer-
tained that male moths have come from a dista
THE TUSSEH SILKWORM MOTH. 123
equal to a hundred miles and upwards. I of course,
cannot vouch for the truth of this, but have no.
hesitation in declaring that I believe it. The Jar-
roo worm is guarded on the trees in like manner as
the Bughy ; this I have had opportunities of seeing
on the hills westward of me: the cocoons are darker
coloured than the Bughy species, and are wound off
as described above. The accompanying skein I had
reeled off at my elbow this morning ; it consists of
five Jarroo cocoons at first, of four when one cocoon
was finished, and of three when two cocoons were
ended. I then stopped the reel ; the three that re-
mained of course gave a filament the entire length
of the skein.
‘ There is still another species of wild silkworm
produced in the Burbhoom hills, which I heard is.
more capable of being domesticated than the one
above described; but I dare say you will excuse
my saying any thing respecting it, as I can only
speak from hearsay, the insect not being produced
in these hills.
‘I send you herewith,’ says Mr Atkinson, in a
subsequent communication for Dr Roxburgh, ‘a
specimen of Bughy Tusseh silk. I kept the co-
coons by me several days after they had been steep-
ed in the alkaline ley, and they reeled just as well as
if they had been newly soaked. The cocoons do
not, I think, differ from those of the Jarroo species,
except that they are lighter coloured. I send one

which the moth has pierced, and will send for more —
to take down with us. There are none of the
- Palma Christi species of Tusseh to be had here, but
I have sent for some. I fancy this last is the most.
valuable kind, for the silk piece wove from it is’
uncommonly durable. The head sircar of the fac-
tory here has an outside cover of a palanquin, which, -
he tells me, has been worn eleven years ; also some
purdahs, which, he says, have been in constant us
nine years, and are not much decayed yet. I re-
member examining the palanquin cover about five
or six years ago. |
‘I have heard that there is another ‘variatio
of the Tusseh silkworm in the hills near Baugli
pore ; its cocoon is said to be smaller than the co-
coons of the Bughy and Jarroo species; perhaps
this may be the kind furnished to Doctor Roxburg
by Major Hutchinson: but, after all, I confess it ma
be suspected that all the variations are derived fro
the same insect originally, and that they hay
assumed different habits by different modes of cul
ture or food.
‘ When I return from Caleutta, I shall mak
particular inquiries on the subject.
‘ You will observe that the inclosed specimen
is tinged of a deeper colour than the filament of th
cocoon; this they say is from the alkaline ley.’
“‘ Mr Atkinson has, since writing the foregoin
letters, sent me large supplies of the cocoons of bo
THE TUSSEH SILKWORM MOTH. 125
the Bughy and Jarroo insects, and I have received
parcels of them from other quarters. These have
all produced their insects ; and after minute inves-
tigation, 1 am not able to observe any difference,
except in the size, and that is even trifling, so that
I can at most only call them varieties of the same
species. But very different is that which lives on
the leaves of the Palma Christi plant, a species I am
now able to give an account and drawings of, having
often reared and conducted them through their vari-
ous stages, in my own room, within these three
years.
“« This moth is called the Bughy by the natives of
the Burbhoom hills, where the silk (which the same
people call Z'wsseh) is manufactured.
«¢ They are found in such abundance, over many
parts of Bengal and the adjoining provinces, as to
have afforded to the natives, from time immemorial,
an abundant supply of a most durable, coarse, dark
coloured silk, commonly called Tusseh silk, which
is woven into a kind of cloth called Tusseh doot’hies,
much worn by Bramins and other seets of Hindoos.
This substance would, no doubt, be highly useful
to the inhabitants of many parts of America and
the south of Europe, where a cheap, light, cool,
durable dress, such as this silk makes, is much
wanted.”
This cloth, though of a loose texture, is uncom-
monly durable, wearing constantly for fifteen or
126 THE TUSSEH SILKWORM MOTH.
twenty years; a garment made of it is scarcely
worn out in the life of one person, but often de-
scends from mother to daughter ; even the covers of ©
palanquins made of it, though exposed to the in-—
fluence of weather, last many years.

‘ * Mr Atkinson, who furnished me with the most
nteresting parts of the history of Tusseh silkworms,
jas also contributed most of the following remarks
pn this species.
«© They are, like the common silkworm, reared in
domestic state, and entirely fed on the leaves of
he Palma Christi plant. Their cocoons are re-
markably soft and white, or yellowish ; the fila-
ment so exceedingly delicate as to render it imprac-
iticable to wind off the silk: it is therefore spun like
feotton. The yarn thus manufactured, is wove into
a coarse kind of white cloth, of a seemingly loose
ftexture, but of incredible durability, the life of one
(person being seldom sufficient to wear out a gar-
ment made of it ; so that the same piece descends
Hrom mother to daughter.
- “< Since I last wrote to you,’ says Mr Atkinson,
‘Ihave reared two parcels of Palma Christi silk-
worms, with a view towards winding off the cocoons,
but all my endeavours to obtain cocoons that would

'“ The Palma Christi silkworm goes by the
ame name as the plant does among the natives,
which is Arrindy. They accordingly call it Ar-
Bindy-worm Arrindy-thread, Arrindy-cloth, &c.
They rear it in their houses much in the way the
Bilkworm is reared. Their manner of spinning it is
ths follows :—Four or five of the cocoons are fastened
0 a stick stuck in the ground, or sometimes they
hold it in their hand. These are united into one
Jthread, and made fast to a piece of wood, with
hs omething heavy to make it spin round while sus-
fended by the thread: when they let out sufficient
ef the cocoons from their hand, it is twisted by this
piece of wood spinning round, and when well twist-
ed it is wound round the wood, and another length
et out from the hand. The cocoons are spun wet,
but only with cold water. The cloth is woven in
small pieces in a loom, and is as coarse as light vit-
tree, but more open; and on being washed and

In the districts of the Chinese empire most con.

quite free, feeding at will upon the leaves of
mulberry-trees, and undergoing their various meta:
morphoses without the aid of man. They are lefi
quite unmolested until the cocoons are formed

are sheltered and protected by the fostering har
of man. The Chinese have reached high perfees)

One of the greatest difficulties with which the
have to contend, is preventing the premature exelt
sion of the caterpillar from the eggs, to which

ire extremely subject, owing to the dry and hot
nature of the climate. This is effected by getting
the moths to deposit their eggs on large sheets of
gaper, which are taken immediately after being
fextruded, and hung upon a beam of one of the
poms, while the windows are all thrown open, to_
expose them to the free circulation of the air. They

season they are again taken down, and subjected to

fjuantity of salt has been dissolved. Here they are
eft two days, when they are taken out, dried, and
folled up more tightly than before, and each sheet

in the habit of using a ley composed of the ashes of
nulberry-trees, and subject the eggs to the cooling
nfluence of snow water, or expose them on trees to
snow and rain.
The object of all this is to prevent the exclusion

free have expanded. No sooner is this the case

warm and dry place. Next day a repetition of th
same process is adopted, and then the eggs becom
of a pale gray colour. After being a third day
subjected to the same mode of treatment, they ¢
sume a much darker hue, approaching nearly ti
black ; and on the next morning, when the pape
is spread out, the larve are found to have burs
from their confinement in the eggs, and are foun
moving about in a vivacious manner.
The Chinese have recourse to ovens for the si
multaneous hatching the eggs of silkworms in th
higher latitudes of that country ; and the strictes
attention is paid in preserving their receptacles fo
the worms, in high and dry situations ; and ever)
means is adopted to preserve the purity of thi
atmosphere, and the rooms are at the same tim
made quite air-tight. While the worms are ye
young, they are very particular in preventing thei
being disturbed by noise ; but this we believe
be an absurd fancy. The doors of the rooms
which the worms are kept, are always open to t
south. The worms are fed on hurdles, which
placed in frames, ranged in tiers, eight or t
deep, above each other. Great attention is paid '
the uniform temperature of the rooms; and th i
is effected either by carrying chafing dishes ¢},
stoves through the apartments, or by the use ¢j
stoves. Smoke and flame are carefully guard
against, and the contents of a cow-house are ca’

uilly dried in the sun, and used by this people in
preference to every other kind of fuel.
i) Those practised in the rearing of silkworms say,
hat the sooner they can be brought to a state of
Hmaturity the better ; and that the quantity of silk
“which they produce is more or less as they are able
%o effect this. It is considered that the worms are
ost productive when they are fully fed, in from
wenty to twenty-five days; in which case that
each drachm weight of eggs will eventually produce
about twenty-five ounces of silk ; and that, if their
maturity is protracted till the twenty-eighth day,
hat only twenty-one ounces are produced by the
jsame quantity of eggs ; and if they are not full fed
Mefore the lapse of thirty or forty days, that not
ore than ten ounces of silk will be the produce of
ithe above quantity of eggs.
The Chinese say that much depends upon the
ode of feeding, in promoting or retarding the
srowth of silkworms. To ascertain this, we tried
an experiment in the summer of 1833, on some
aterpillars of the Cabbage Butterfly (Pontia Bras-
sicee,) the Papilio Brassicce, volume first, page 186,
vhich had been newly hatched. These we divided,
and placed in two separate tumblers, and put them
upon cabbage leaves. We supplied the larvee in one
of the tumblers plentifully twice a-day with fresh
abbage leaves, while those in the other tumbler
had but a scanty supply, and even allowing them
140 CHINESE MODE OF REARING SILKWORMS.
to be sometimes entirely without food. At the
end of a week, those which had been well fed haé
acquired about a third more in bulk than them that}
were kept on short allowance. About the twelfth}!
day we had carried our starving system so far, that
we had forgot to put leaves to them for nearly}
twelve hours, after they had been completely ex-
hausted ; and next morning we found most of the
caterpillars adhering to the sides of the tumbler, byp
very fine silky filaments. We were apprehensive,}
that, having not been long enough fed, that they}
might die in place of transforming into the chrysalisy
and loosened them all from the sides of the tumblery
and gave them a fresh supply of leaves, which, in
a few minutes, they began to devour very greedily
Next day, while in the act of supplying them with
leaves, we found one of the larve again adhering
by filaments to the piece of paper with which the
tumbler was covered, and determined to leave
undisturbed. It continued in this state for upward
of a day ; and when we next examined it we fount |
that it had changed into the chrysalis condition, but
-was of a very small size, and had a thin transparent
appearance. The caterpillars which had been pro=
perly supplied with food now refrained from eating
and prepared for transforming into chrysalides
Those which had been starved still continued t6
eat, and were much less in size—a little more the
a fourth. When the full fed larve had all changeé

we gave a plentiful supply of leaves, morning and
evening, and in the course of four days several of
ijthem grew considerably, and prepared for their
transformation, and in seven days all of them had
assumed the pupa state. The whole of them in
due time burst from their pupa form, and became
Jperfect insects, except the one which had first be-
some a pupa. On opening it, we found it entirely
empty ; all its vital parts having been completely
dried up and absorbed. We carefully examined
ithe various butterflies, but could perceive no differ-
ence in the size of those which had been ill fed,
Jand those which had revelled in abundance.
From the above experiment, we proved that the
j#period of transformation between the larva and pupa
ondition can be protracted.
In China very rigid attention is given to the cat-
ferpillars in the early stage of their existence, and
jfthey are fed by night as well as by day. The day
jjon which they are hatched they are supplied with
jforty meals, thirty on the second day, and reduced
by certain proportions for some days thereafter, till
hey come to twice a-day. When hazy or damp
weather occurs during the feeding season, the appe-
ites of the caterpillars are considerably affected by
his change of the atmosphere. Those who tend
hem burn straw over the worms, which dries the
air, warms it, and stimulates them to feed freely.

a vulgar error, for we should conceive the contrary

of the caterpillars. Indeed Count Dandolo found,
by strict observation, that this practice had a most:
pernicious effect. The Count says, that on visitin

ieocoons, at which time they are collected into heaps,

lected and placed on hurdles in a dry and airy
ituation. “ The next care is to destroy the chry-
lides in those balls which are to be reeled. The
ost approved method of performing this, is to fill
arge earthen vessels with cocoons, in layers, throw-
in one-fortieth part of their weight of salt upon
ach layer, covering the whole with large dry leaves
esembling those of the water-lily, and then closely
topping the mouths of the vessels. In reeling their
ilk, the Chinese separate the thick and dark from
e long and glittering white cocoons, as the produce
is inferior.” * Bt

INDIAN METHOD OF TREATMENT.
So favourable is the climate of India to the con-
stitution of the Phalena Mori, or Common Silk-
worm, that they are reared in sheds, and not ir
houses as in China. They are constructed of lattice
work, with thatched roofs. They are generally)
fifteen feet broad, and their height from eight to’
nine feet, and length according to the number of
worms to be reared. In the centre of the building,
a path of convenient width is left for the free pas
sage of those who tend them. On each side of this
passage are erected twelve tiers of frame-work,:
made of bamboo, in the form of shallow boxes. In
these the caterpillars are placed ; and when they
are fed their full time, and ready to spin their
cocoons, they are separated, each into a cell formed
of plaited stripes of bamboo ; and when their cocoon |
is completed, they are subjected to nearly the same
mode of treatment as in China.
145
DISEASES OF SILK WORMS.
In European climates the caterpillars of the silk-
orm are liable to many diseases, probably the con-
equence of inexperience in their mode of treatment.
In France and Italy it has long been a common
ractice to give a certain quantity of silkworms to
e peasantry to be reared, and in such hands, as
ight have been expected, the successful cultivation
f these was long but imperfectly known ; and it
as not till the patriotic exertions of Count Dandolo, —
at distinct and settled notions were thought of for
proving the rearing, and preserving, in a healthy
ondition, this most valuable of all insects. He
iligently studied the habits of the silkworm in its
arious metamorphoses, and immediately made
own every discovery he had made, either by his
itings or by giving personal instructions to those
oncerned in the propagation of the worms. He
ublished an enlightened treatise on the subject,
hich soon led to the formation of large establish-
ents in Lombardy. These were named Dandoliéres,
in honour of this patriotic nobleman.
Damp stagnant air, and the presence of carbonic
acid gas, appears to be one of the proximate causes
146 DISEASES OF SILKWORMS.
of disease in silkworms ; but of these damp seems to’
be the most prejudicial, as will be seen by the fol-
lowing experiments :—* If a silkworm,” says Dy
Lardner, “is introduced into a receiver charged
with carbonic acid gas, and in which a bird would
instantly die, although the worm quickly exhibits
signs of uneasiness and suffering, it will live for ten,
fifteen, or perhaps twenty minutes. No wa
blooded animal could continue alive in such an at
mosphere for half that time. If, after remaining ¢
few minutes, the worm be withdrawn from the re-
ceiver, it will not exhibit any sign of injury, bu
will be apparently as healthy as before inhaling
this pernicious gas. The silkworm appears endueé
with the power to seize upon the minutest portion
of vital air which may be held by water, as it wi
live for some minutes immersed in this fluid, pars
ticularly in its first ages ; and, even when seemingly
dead, it will revive if taken out. It would seem,
however, that when its power of breathing is ob
structed, the worm instantly dies. If, instead 0}
plunging it in carbonic acid gas, or in water, i s
eighteen breathing holes are sealed up with greas
it expires instantaneously. t
“ If a healthy silkworm be confined in a vessely

heated to the temperature of 80° to 90°, it wi

aporation will be obstructed, the secretions in-
ispensable to vitality, which are effected in this
imal by means of contraction,* will be suspended,
1d erelong it will perish. A warm-blooded ani-
‘Ymal, on the contrary, if sufficiently supplied with
e air, can live without any suffering, and per-
| all its functions without inconvenience, in such
, temperature, whatever be the attendant degree

structure of these two classes of animals.”

obacco has been ascertained to be a deadly poison to
ilkworms. Ifa few grains of snuff is thrown on them,
mmediate pain seems to be felt, from the writhing
f the animal; in about a minute convulsions will
nsue, and death speedily follows. Before the cat-
rpillar expires, it ejects from its mouth a watery
iquid ; and should another larve be touched with
this fluid, it is certain to prove fatal.
There is a disease to which silkworms are very
iable in the south of France, which is called the
jaundice, from the yellow colour exhibited by the
animal while labouring under the malady. This

that the disease has its origin in mephitie vapours,
arising from decayed leaves, and that the lime,
which has a strong affinity for these gases, may
absorb the vapour, and thus render the apartment
healthy and pure; which is most. satisfactorily
proved by the experiments of Mons. Blanchard,
which we shall give in his own words. He says
“Having procured four glass jars, nine inches im
depth and five in diameter, and had cork stoppers
fitted to them. In each of these I put twelve silks

I had fed four times a-day, and confined them i
this kind of prison during their lives, and neve

are with them. Those without lime never pro-
uced more than three small and imperfect cocoons,
while in those which were sprinkled with lime, I
ad very often twelve, and never fewer than nine
I-sized cocoons.” He found that even a large
roportion of lime had no bad effect on the worms.
The method which Count Dandolo practised, was
he fumigation of the apartments with chlorine gas,
Ithough this is attended with danger. Chlorade
f lime, however, is less hazardous, and produces
ually beneficial effects in clearing apartments of
oxlous vapours.

ON THE CHEMICAL PROPERTIES OF |
SILK. i
THE rich yellow colouring matter which tinges
all silk, more or less in its raw state, is in combi.
nation with:the gum. Immersing the cocoons i 1
hot water will dissolve, to a certain extent, this
gum, and leave a yellow tinge in the water. But
the use of alcohol instead of water, will dissolve
this matter in greater quantity. This tincture will
retain its colour with little loss of intensity, even
after being long exposed to the rays of the sun.
The fact of this affinity of the colouring matter of sill
for alcohol, suggested to Mons. Baumé the idea of
bleaching silk in the following manner. )
He constructed a twelve gallon stoneware vessel,
of a form nearly conical, with a wide opening
the top, and a smaller one, of about an inch
diameter, at the bottom, which was stopped by
cork ; through the centre of which was passed
glass tube, of a quarter of an inch diameter. Th
tube was always stopped by a cork, except at t
time wken the liquid required to be drawn of
The inside of the vessel was polished very smoo
with pumice-stone, to prevent the roughness frot
breaking the threads in their first state.
ON THE CHEMICAL PROPERTIES OF SILK. 151
In this vessel were placed six pound weight of
ellow raw silk, over which he poured a composi-
ftion, consisting of a mixture of forty-eight pounds
Hof alcohol (whose specific gravity was 0.867), with
}iwelve ounces of muriatic acid in its purest state,
of the specific gravity of 1.114.) The vessel was
hen closed tightly up, and the contents left to
digest, until the liquor became of a dusky brown
mcolour ; which operation usually required about
twenty-four hours. This liquor was then drawn
off by means of the glass tube, and spirit of wine
was constantly poured into the vessel, while the
tube was left unstopped, till the liquor passed off
perfectly clear, and totally free from colour. The
silk was then allowed to drain, until it ceased to
drop. Spirit of wine and muriatic acid of the same
roportions were again poured on it, and the silk
allowed to continue immersed for forty-eight hours ;
by which time it had parted with all its colouring
matter, and had assumed a brilliant white.
With respect to the exact time required for the
immersion of the silk in the alcohol and muniatic
acid, much will depend on the original colour of the
silk, and also the temperature; and M. Baumé
ascertained, that the silk wound from those cocoons
which had not been previously baked, to destroy the
aurelise, was much more easily bleached ; and that,
on the second immersion, the liquor, when drawn
off, was of a much paler hue, and so slightly was
152 ON THE CHEMICAL PROPERTIES OF SILK.
its chemical properties changed, that by the addi
tion of half the original portion of muriatic acid)
the liquid might be employed for a first immersion
~ of the raw silk. =f
The bleaching operation was completed by pours)
ing upon the silk forty-eight pounds of pure spi
of wine, which was allowed to remain from twenty=
four to thirty hours on the silk. There is great
difficulty in freeing the muriatic acid from the silk,
which can only be effectually done by subjecting i
to a continued stream of running water for so
hours.* . ;
In England a different process is pursued, whick
is by immersing the silk in a solution of soap im
river water, while it is kept at the boiling point for)
two or three hours; when it is taken out, well’
beaten either with a machine constructed for the
purpose, or with a wooden mallet, and afterwards:
washed in river water. It is then wrung, 2a
again immersed in soap and water, in a cold state,
with the addition of a small portion of indigo, and’
brought to the boiling point ; at which it is allowed
to continue for a short time. It is then taken out,
wrung, and shaken ; and dried in a stove construct=_
ed for the purpose, over the fumes of burning)
sulphur, which render it of the most beautiful}
whiteness. a
* See Ure’s Dict. of Chemistry, article Bleaching, for
more full detail of this process.
ON THE CHEMICAL PROPERTIES OF SILK. 153
Nitric acid has a strong influence upon silk ; and,
if mixed with alcohol, changes silk to a permanent
bright golden yellow colour. Thesame acid, when
oncentrated and distilled off silk, yields by evapo-
tation oxalic acid; and if the evaporation is still
farther continued, the same acid, together with a
Fquantity of yellow octohedron-sided truncated crys-
als are obtained. These are free from an acid
aste, but of a strong bitter, and if applied to the
skin leaves a deep yellow stain. When the re-
aining liquor is saturated with potash, and eva-
porated, the residue is a rather yellow salt, which
| detonates when placed on live coals, like nitre.
Chemists suppose this to be a treble combination of
|
he bitter principle above mentioned, together with
nitrate of potash.
1 Silk is dissolved and corroded by the caustic
} alkalis; and chlorine renders it yellow. It
ields a greater quantity of volatile alkali than
ost any other substance. It was found by
ournefort to contain even more than hartshorn, as
he obtained from fifteen ounces of silk two drachms
fof volatile salt. This preparation was at one
ime in high repute in England as a medicine ;
and was called English Drops, or “ Guttee Angli-
ane.” The cocoons of silk were reduced into a
powder by Pomet, and used as a medicine. In his
SHistory of Drugs he says, that silk thus prepared had

It is said, that if a thin silk veil is worn i
countries where malaria is generated, that it wil
have the effect of counteracting its noxious qué
lities.
The water in which cocoons are immersed prepa-
ratory to reeling, acquires such a strong lathery
consistence, that air-bells may be made with it,
which are so flexible and strong that they have beer
known to remain without bursting for upwards of
twenty-four hours. These bells exhibit the pris:
matic colours in as high a degree as those formed 6

Count Rumford observed, that raw silk has €
remarkable power of producing pure air from water
He found that, by introducing thirty grains of thi
substance, first washed in water, into a thin glast
globe, four inches and a half in diameter, having €
cylindrical neck three-fourths of an inch wide, and
twelve inches long, inverting the globe in a j
filled with water, and exposing it to the action

the silk became covered with an infinite number
air-bubbles, gradually increasing in size, till, at tl
end of two hours, the silk was buoyed up by the
means to the top of the water. They separated
themselves by degrees, and formed a collection

ir in the upper part of the globe, which, when
‘}xamined by the established test, appeared to be
ery pure. In three days he collected three and
hree quarters of a cubic inch of pure air, into which
wax taper being introduced, that had just before
n blown out, the wick only remaining red, it
stantly took fire, and burned with a bright and
e flame. The water in the globe had acquired
he smell of raw silk ; it lost something of its trans-
arency, and assumed a faint greenish cast.
It was observed, that when this experiment was
ade in the dark, only a few inconsiderable bubbles
ere formed, which remained attached to the silk ;
or was it otherwise when the glass globe was re-
oved into a German stove. In the latter case,
deed, some single bubbles had detached themselves
om the silk, and ascended to the top, but the air

ilk, even under circumstances peculiarly unfavour-
ble to the preservation of animal substances, forms
nother of its qualities which is deserving of re-
ark. Some years ago, the sexton of the parish of

157
| ELECTRICAL PROPERTIES OF SILK.
THE distinction between those bodies which are
apable of being excited to electricity, and those
hich are only capable of receiving it from the
thers, appears scarcely to have been even sus-
cted till about the year 1729, when this great
iscovery was made by Mr Gray, a pensioner in
he Charter-House. After some fruitless attempts
o make metals attractive by heating, rubbing, and
ammering, he conceived a suspicion, that, as a
lass tube, when rubbed in the dark, communi-
ted its light to various bodies, it might possibly,
flat the same time, communicate its power of at-
fitracting to them. In order to put this to the
test, he provided himself with a tube three feet
five inches long, and near an inch and one-fifth in
diameter ; the ends of the tube were stopped by
cork ; and he found that, when the tube was ex-
cited, a down feather was attracted as powerfully
by the cork as by the tube itself. To convince
himself more completely, he procured a smail ivory
ball, which he fixed at first to a stick of fir, four
inches long, which was thrust into the cork, and
found that it attracted and repelled the feather even
158 ELECTRICAL PROPERTIES OF SILK.
with more vigour than the cork itself. He aftera}
wards fixed the ball upon long sticks, and upo
pieces of brass and iron wire, with the same suc
cess ; and lastly attached it to a long piece of pack-
thread, and hung it from a high baleony, in which
state he found that, by rubbing the tube, the ball
was constantly enabled to attract light bodies i
the court below.
His next attempt was to prove whether this
power could ‘be conveyed horizontally as well as
perpendicularly. With this view, he fixed a cord
to a nail which was in one of the beams of the
ceiling ; and making a loop at that end which hung
down, he inserted his packthread, with the ball
which was at the end of it through the loop of thé)
cord, and retired with the tube to the other end of
the room ; but in this state he found that the ball .
had totally lost the power of attraction. Upon
mentioning his disappointed efforts to a friend, it)
was suggested that the cord, which he had used to)
support his packthread, might be so coarse as t¢
intercept the electric power ; and they accordingl1
attempted to remedy this evil by employing a sill
string, which was much stronger in proportion than”
a hempen cord. With this apparatus the experi- |
ment succeeded far beyond their expectations
Encouraged by this success, and attributing i
wholly to the fineness of the silk, they proceeded
to support the packthread, to which the ball wa

attached by very fine brass and iron wire, but, to
heir utter astonishment, found the effect exactly
he same as when they used the hempen cord ; the
lectrical virtue utterly passed away ; while, on the
#ther hand, when the packthread was supported by
a silken cord, they were able to convey the electric
virtue seven hundred and sixty-five feet.
It was evident, therefore, that these effects de-
pended upon some peculiar quality in the silk,
Svhich disabled it from conducting away the elec-
rical power, as the hempen cord and the wire had
done.
§ The accidental discovery of Mr Gray led to
whe knowledge of the non-conducting powers of —
fvarious other substances; and since the nature
fof electricity has been more deeply investigated,
Mthe true electric properties of most substances have
become known, and are now divided into elec-
ics and non-electrics. The following substances
are among the principal conductors of the electric
uid; namely, stony substances in general, more
especially those of a calcareous nature, such as lime,
marble, &c., sulphuric acid, black pyrites, black
lead, alum, charcoal, all the metallic ores, the ani-
mal fluids, and all other fluids excepting air and
foils.
i The electric bodies are those substances which,
when excited, collect or omit this fluid, such as
amber, sulphur, jet, glass, and all precious crystal-

lized stones, all resinous compounds, and all dry
substances, such as silk, hair, wool, paper, &c. :
Silk was first discovered to be an electric by
Gray, in the manner we have already related ; bu
as it was by no means remarkable for emitting
sparks, which most commonly engages the atten-
tion, its electric virtues were almost entirely over-
looked till the year 1759. At that time Mr
Symmer presented to the Royal Society some pa~
pers, containing a number of very curious experi-
ments made with silk stockings, in substance as
follows :—
He had been accustomed to wear two pairs of
silk stockings, a black and a white. When thes e
were put off both together, no signs of electricity
appeared ; but on pulling off the black ones from
the white, he heard a snapping or crackling noise,
and in the dark perceived sparks of fire between
them. To produce this and the following appear
ances in great perfection, it was only necessary to
draw his hand several times backward and forward
over his leg with his stockings upon it. .
When the stockings were separated, and held at
a distance from each other, both of them appeared!
to be highly excited ; the white stocking positively,
and the black negatively. While they were kept
at a distance from each other, both of them appeared)
inflated, to such a degree, that they exhibited th
entire shape of the leg. When two black or two)
ELECTRICAL PROPERTIES OF SILK. 161
vhite stockings were held in one hand, they would
pel one another with considerable force, making
n angle seemingly of thirty or thirty-five degrees.
hen a white and black stocking were presented
o each other, they were mutually attracted ; and,
permitted, would rush together with surprising
iolence. As they approached, the inflation gra-
ually subsided, and their attraction of foreign
bjects diminished, but their attraction of one an-
“ther increased ; when they actually met, they be-
me flat, and joined close together like as many
olds of silk. When separated again, their electric
irtue did not seem to be in the least impaired for
aving once met ; and the same appearances would
exhibited by them for a considerable time. When
ithe experiment was made with two black stockings
one hand, and two white ones in the other, they
ere thrown into a strange agitation, owing to the
fattraction between those of different colours, and
the repulsion between those of the same colour.
# This mixture of attractions and repulsions made
the stockings catch at each other at greater distances
than otherwise they would have done, and afforded
a very curious spectacle.
When the stockings were suffered to meet, they —
stuck together with considerable force. At first Mr
Symmer found they required from one to twelve
ounces to separate them. Another time they raised
seventeen ounces, which was twenty times the
162 ELECTRICAL PROPERTIES OF SILK.
weight of the stocking that supported them, 2
this in a direction parallel to its surface. Wher
one of the stockings was turned inside out, and pi
within the other, it required twenty ounces to s@}
parate them; though at that time ten ounces wer
sufficient when applied externally. Getting tk
-black stockings new died, and the white ones
washed, and whitened in the fumes of sulphur, ¢ n
then putting them one within the other, with th
rough sides together, it required three pounds
three ounces to separate them. With stockings oj
a more substantial make, the cohesion was. stil
greater. When the white stocking was put within
the black one, so that the outside of the white was
contiguous to the inside of the black, they raised
nine pounds, wanting a few ounces ; and when the
two rough surfaces were contiguous, they raised!
fifteen pounds one pennyweight and a half. Cute
ting off the ends of the thread, and the tufts of sill
which had been left in the inside of the stockings,
was found to be very unfavourable to these experi
ments.
Mr Symmer also observed, that pieces of whi
and black silk, when highly electrified, not only”
eohered with each other, but would also adhere to)
bodies with broad and even polished surfaces,
though these bodies were not electrified. This hey
discovered accidentally ; having, without desigr
thrown a stocking out of his hand, which stuck to)
ELECTRICAL PROPERTIES OF SILK. 163
Hhe paper-hangings of the room. He repeated the
Pxperiment, and found it would continue hanging
“hear an hour. Having stuck up the black and
White stockings in this manner, he came with an-
| ther pair highly electrified; and applying the
“vhite to the black, and the black to the white, he
arried them off from the wall, each of them hang-
g to that which had been brought to it. The
amie experiments held with the painted boards of
he room, and likewise with the looking-glass, to
She smooth surface of which both the white and the
black silk appeared to adhere more tenaciously than
o either of the former.
® Similar experiments, but with a greater variety
of circumstances, were afterwards made by Mr
®igna of Turin, upon white and black ribands.
He took two white silk ribands just dried at the fire,
d extended them upon a smooth plane, whether
conducting or electric substance was a matter of
difference. He then drew over them the sharp
dge of an ivory ruler, and found that both ribands
ad acquired electricity enough to adhere to the
lane; though, while they continued there, they
jhowed no other sign of it. When taken up sepa-
ately, they were both negatively electrified, and
would repel each other. In their separation, electric
parks were perceived between them; but when
again put on the plane, or forced together, no light
Iwas perceived without another friction. When, by
164 ELECTRICAL PROPERTIES OF SILK.
the operation just now mentioned, they had a
quired the negative electricity, if they were place
not upon the smooth body on which they had be
rubbed, but on a rough conducting substance, the
would, on their separation, show contrary electrie
ties, which would again disappear on their being joit
ed together. If they had been made to repel ez
other, and were afterwards forced together, ar
placed on the rough surface above mentioned, they
would in a few minutes be mutually attracted,
the lowermost being positively, and the uppermost
negatively electrified. *
If the two white ribands received their friction
upon the rough surface, they always acquired cons
trary electricities. The upper one was negatively
and the lower one positively electrified, in what.
ever manner they were taken off. The same changé
was instantaneously done by any pointed conducto

communicate electricity to one which had not as y
received it, viz. laying the unelectrified riband u

mplaced a riband that was not quite dry under an-
#>ther that was well dried at the fire, upon a smooth
lain; and when he had given them the usual
iction with his ruler, he found that, in what
anner soever they were removed from the plane,
€ upper one was negatively, and the lower one
sitively electrified —If both ribands were black,
these experiments succeeded in the same man-
er as with the white. If, instead of the ivory
ler, he made use of any skin, or a piece of smooth
lass, the event was the same; but if he made use
f a stick of sulphur, the electricities were in all
es the reverse of what they had been before the
ibands were rubbed, having always acquired the
sitive electricity. When he rubbed them with
paper, either gilt or not gilt, the results were un-
rtain. When the ribands were wrapped in paper,
Weilt or not gilt, and the friction was made upon the
paper laid on the plane above mentioned, the rib-
ilands acquired both of them the negative electricity.
If the ribands were one black and the other white,
whichever of them was laid uppermost, and in
whatever manner the friction was made, the black
generally acquired the negative, and the white the
positive electricity.
~ He also observed, that when the texture of the
upper piece of silk was loose, yielding, and retiform,
like that of a stocking, so that it could move and
be rubbed against the lower one, and the rubber

was of such a nature as could communicate bu
little electricity to glass, the electricity which the
upper piece of silk acquired did not depend upor
the rubber, but upon the body on which it was
laid. In this case, the black was always negative
and the white positive. But when the silk was
hard, rigid, and of a close texture, and the rubber
of such a nature as would have imparted a great
degree of electricity to glass, the electricity of the
upper piece depended on the rubber. Thus, ¢
white silk stocking, rubbed with gilt paper upon
glass, became negatively, and the glass positivel
electrified. But if a piece of silk of a firmer tex-
ture was laid upon a plate of glass, it was alway
electrified positively, and the glass negatively, if it
was rubbed with sulphur, and for the most ee if
it was rubbed with gilt paper.
If an electrified riband was brought near an
insulated plate of lead, it was attracted, but very
feebly. On bringing the finger near the lead, a
spark was observed between them, the riband wa ;
vigorously attracted, and both together showed no
signs of electricity. On the separation of the riband,
they were again electrified, and a spark was peng
ceived between the plate and the finger.
When a number of ribands of the same ecloull
were laid upon a smooth conducting substance, and
the ruler was drawn over them, he found, that
when they were taken up singly, each of them gave
ELECTRICAL PROPERTIES OF SILK. 167
Isparks at the place where it was separated from the
other, as did also the last one with the conductor ;
d all of them were negatively electrified. If
hey were all taken from the plate together, they
ohered in one mass, which was negatively electri-
ied on both sides. If they were laid upon the
bugh conductor, and then separated singly, begin-
1ing with the lowermost, sparks appeared as before,
but all the ribands were electrified positively,
except the uppermost.—If they received the friction
upon the rough conductor, and were all taken up
at once, all the intermediate ribands acquired the
lectricity, either of the highest or lowest, according
as the separation was begun with the highest or
he lowest. If two ribands were separated from
the bundle at the same time, they clung together,
jand in that state showed no sign of electricity, as
one of them alone would have done. When they
were separated, the outermost one had acquired
an electricity opposite to that of the. bundle, but
uch weaker.
A number of ribands were placed upon a plate
of metal, to which electricity was communicated
by means of a glass globe, and a pointed conductor
held to the other side of the ribands. The conse-
quence was, that all of them became possessed of
the electricity opposite to that of the plate, or of
the same, according as they were taken off; except

opposite to that of the plate.
The following experiments were performed |

tion, as well as the action of points, and the di
tion of the fluid in positive and negative electricit
1. A glass cylinder was mounted, and a cushi
applied with a silk flap, proceeding from the ed
of the cushion over its surface, and thence hi
round the cylinder. The cylinder was then exci
by applying an amalgamed leather in the usu
manner. ‘The electricity was received by a cot
ductor, and passed off in sparks to Lane’s elect
meter. By the frequency of these sparks, or by
number of turns required to cause spontaneous é;
plosion of a jar, the strength of the excitation w
ascertained.
2. The cushion was withdrawn about one i
from the cylinder, and the excitation performed |
the silk only. A stream of fire was seen betwee
the cushion and the silk ; and much fewer spar.
passed between the balls of the electrometer.
8. A roll of dry silk was interposed, to preve
the stream from passing between the cushion ¢
the silk. Very few sparks then appeared at
electrometer.
4. A metallic rod, not insulated, was then inters)
posed instead of the roll of silk, so as not to touch |

y part of the apparatus. A dense stream of
electricity appeared between the rod and the silk,
and the conductor gave very many sparks.
5. The knob of a jar being substituted in the
place of the metallic rod, it became charged nega-
tively.
6. The silk alone, with a piece of tinfoil applied
behind it, afforded much electricity, though less
than when the cushion was applied with a light
pressure. The hand being applied to the silk as a
eushion, produced a degree of excitation seldom
equalled by any other cushion.
7. The edge of the hand answered as well as the
palm.
8. When the excitation by a cushion was weak,
a line of light appeared at the anterior part of the
cushion, and the silk was strongly disposed to re-
ceive electricity from any uninsulated conductor.
These appearances did not obtain when the excita-
tion was by any means made very strong.
9g. A thick silk, or two or more folds of silk, ex-
cited worse than a single very thin flap. The silk
used was that which the milliners call Persian.
10. When the silk was separated from the cylinder,
sparks passed between them ; the silk was found to
be in a weak negative, and the cylinder in a posi-
tive state.
The foregoing experiments show that the office

SOME MOTHS REJECTED BY BIRDS.
Mr BiytH mentions, in the Field Naturalist’s
Magazine,* a singular circumstance, which is quite
ew to us, namely, that the Magpie Moth (Adrazxas
rossulariata) is rejected as food by various in-
ectiverous birds, but is unable to account for the
cause of this. “ I have a nightingale,” says he,

The same gentleman has made another interes
ing discovery respecting the eyes of the Dark Arch
Moth. He says:—* A few weeks ago, on seei
a remarkably fine specimen of the Dark Are

placed it m a small box, which I happened to ha

This specimen was captured near Oxford in

In addition to what we have said on this subject
Jat page 100, volume I., we subjoin the following
Hremarks :—That “ the extent to which insects mi-
} grate,” says Mr Blyth, “ or rather wander, seems
never to have sufficiently engaged the attention of
entomologists. Most persons must have remarked,
on perusing an account of the localities of our rarer
strong-winged insects (such as the Sphingide, many
of the butterflies, &c.,) how very many of them
}have been principally taken on the eastern and
}southern coasts of the kingdom. My friend, to
whom I am indebted for the above information on
birds, mentions having seen several small moths
flying out at sea, when about ten miles distant from
the Suffolk coast ; one only of which was captured,
Wwhich I find to be the Lampetia defoliaria. Mr
| Stephens, also, records an instance of the Death’s-
head Hawk-moth (Acherontia atropos) being cap-
| tured four miles at sea ; and I have myself observed

flies, flying at a considerable distance from land.

seen specimens from America, from the Caucasus,
and from China; I have seen them from No
America: the species is said also to occur in Ota
heite and Australia, and it is undoubtedly found
in Africa. Reports, however, of this kind must be
received with some degree of caution, as, withou

actual and careful comparison, distinct species may
ave been confounded together. Many birds (par-
icularly of the order Grallatores) were once thus
id to inhabit all parts of the globe; until it was
shown, by careful and minute comparison, that
different creatures had been confused together: I
allude to the species of Scolopaz, Charadrius, Tha-
lasidroma, &e., which, though closely resembling
each other, are now proved, by various and constant
characters, to be distinct. There can, however, be
no doubt but that the Painted Lady Butterfly has
an amazingly wide range of geographical distribu-
tion, and I think it may be fully accounted for by
the strange wandering propensities of the insect.
‘“‘ Of this I have just witnessed a very remark-
able example. I had often observed this species _
to fly straight out to sea, and I have noticed it ata
considerable distance from land; but, until within
this last fortnight, I never knew them travel in
immense flocks. On the 8th of this month, (Oc-
tober 1833,) this beautiful butterfly abounded in
all the gardens about this place; upwards of
twenty were counted on one clump of dahlias ;
and, at the same time, they were noticed in equal
abundance in a garden about half a mile distant
from that in which those dahlias grew. None
had been previously observed in the neighbour-
hood, and all that were seen on that day were very
much rubbed and injured, so that they had evi-

they came, neither could I discover the routé)
which they pursued ; for a single day the species
appeared every where in abundance, and the da
after not one was any where to be seen. On th
morning of the 10th, however, I observed a sin
one flying swiftly to the eastward ; and since thag)
time several others have been seen; but, as thes
last were all perfect and uninjured insects, I ¢
not consider that they formed part of the immens
flight which passed this place on the 8th. It w

however, from the present subject, to treat on the
wonderful irregularity of insect appearance ; some
eurious facts concerning this I will reserve for a
future opportunity ; but it is nevertheless worthy
of being observed here, that the Painted Lady
Butterfly, which is remarkable, in most places, for
the extreme irregularity of its occurrence, is equally
remarkable in others, (as in some parts of the west
of England, and in Jersey,) for appearing with
great regularity.
*« A very singular circumstance is also related of
the Cynthia Cardui, by Mr Knapp, in his amusing
and excellent ‘ Journal of a Naturalist.’ After
some other remarks on the species, he observes that
‘ some years ago a quantity of earth was raised in
cutting a canal in this county (Gloucestershire ;)
and in the ensuing summer, on the herbage that
sprang up from the new soil on the bank, this but-
terfly was found in abundance, where it had not
been observed for many years before.’ Might we
not reasonably expect, if the soil about Hamp-
stead were to be turned up, on any occasion, to
some depth and extent, that the extraordinary and
distinctly marked butterfly, Cynthia Hampstedien-
sis, would reappear, although so many-years have
now elapsed since it was last seen ?” *

ORGANS OF HEARING.
THERE is no part of the physiology of inse
more interesting, and yet still in such doubt, ¢
whether or not they enjoy the sense of hearing i
the same manner as other animals..
Professor Rennie has published, in the Fie
Naturalist’s Magazine, several papers containi
some very interesting discussions on this subject
which we shall endeavour to condense, adding su
matter as occurs to us as throwing light on this in
tricate suject. In the first place, he has translate
Straus-Diirckheim’s excellent paper, from his wor
on articulated animals.
It is now generally ‘believed that the antenns
are the organs of hearing ; and this idea is strongly
supported by Diirckheim. In condemning the notio
of their being the organs of touch, he says, ‘* Man
insects, besides, have their antenne so short, the
they would be obliged to stand erect on the crown”
of their heads in order to come at the bodies which
they might thus wish to explore, and for this their |
feet are much better adapted. |
“ Since almost all articulated animals possessing
a solid skin have antennee, which are furnished’

ith nerves of an extraordinary thickness in pro-
portion to their own size, there cannot remain a
doubt that they are organs of some sense, and that
too a very acute one.
«I have said, that insects are proved by obser-
vation to be furnished with an organ of hearing. It
is, indeed, scarcely probable that creatures such as
the tree-hopper (Cicada), and the locust (Locusta),
to which nature has given the faculty of producing
a peculiar sound, by means of an appropriate organ,
should, at the same time, be deprived of the means
of hearing such sounds, inasmuch as these can have
reference only to their own kindred. It is still
farther proved, that these insects share the faculty
of hearing, along with all other living beings, by
their ceasing to sing the instant they fear they
have been discovered.” *
«< T once was observing,” says Kirby, ‘ the mo-
tions of a weevil (Apion) under a pocket micro-
I scope: on seeing me, it receded. Upon my making
a slight but distinct noise, its antenne started: I
repeated the noise several times, and invariably
with the same effect. A beetle (Haspalus,) which
I was holding in my hand, answered the sound in
the same manner repeatedly. I will now mention
another effect that I observed, still more remark-
able. A little moth was reposing upon my window ;

if to listen. It is necessary, however, to remé
that there is a want of precision in these expe
ments, as no precautions are mentioned to have be
taken to hide the cause of the noise from the ey
of the insect.” *
“ It is important to remark, with regard to thi
inquiry, that no effect is likely to be produced upom
insects by sounds unconnected with their habits ;
for even the timid hare will scarcely bend its ear

will instantly rouse them. The same holds wit
respect to insects ; and accordingly the quick-eared

fof this order alive, we have repeated these experi-
ments in every possible form; but the most im-
portant, with respect to the antenne, is that, when -
fa leaf or a bit of paper is rustled under a table,
the green grashopper (Acrida viridissima) im-
mediately bends one or both of its long antenne
Hin the direction of the sound, just as a rabbit would
Hdo its ears if similarly alarmed. The same effect
His produced when a large beetle, in a box, is placed
out of sight near it; and when placed behind, it
bends the antenne back over the body, and bustles
to get out. It is obvious to us, indeed, that it is
partly, if not wholly, in consequence of the great
ength of their antenne that these insects hear so
eutely ; and we think we have remarked that the
species in which they are short have a less perfect
sense of hearing. In the capricorn beetles (Lamia,
§c.), which live on the wood and bark of trees, the
antennee are also very long, for the purpose, it may

his opinion is founded partly on the analogy of what
yecurs in the larger animals, who prick up their ears
inder similar circumstances in order to hear better ;
nd partly because, on following the progress of
legradation in the organ of hearing from the first

ated animals, by a sort of transition occurring in

Which this organ occurs in the simplest form, com-
dared with that of superior animals.”

mean, that the joints of the antenne perform th
same functions as the chain of small bones in

a similar chain, and transmit the vibrations of th

On this subject, Bonsdorf says, “ There a
none who know not that there exist many kine
of insects which can produce sounds variously 1

exciting which they are furnished with proper ir
struments, which will be explained more fully (

while they call forth the whole hive in defence of
the state against the attacks of enemies; another,
} while they clean their hives from filth; and an-
Jother, whilst the queen-bee leads forth a swarm to
Hseek new settlements. Now, I ask those who deny
j hearing to insects, what can be the use of sounds
}so variously modulated, unless the bees can by
J hearing discriminate those sounds ?” *
““ Not once, but a hundred times, I have tried by
experiment the acuteness of hearing in insects, as
ften as I have delighted my mind with contem-
i plating the beauties of nature in study during the
summer nights, destined otherwise for the purpose
of recruiting exhausted strength. In such cases,
Show much attention is requisite to avoid disturbing
ithe roaming moths, and how rapid is their flight on
ithe least noise being made, even before I could have
imagined that the noise could have reached their
ears.
«¢ Unless, therefore, every circumstance misleads
me, the inference is correct, that there is a constant
Hrelation between the power of expressing various
sounds and the power of perceiving the same ; and
this is strengthened the more as it is more clearly
fiseen and proved by sad experience in the case of a
man born deaf and dumb, which appears to prove
* Field Naturalist’s Magazine, i. p. 295.
188 ORGANS OF HEARING,
that hearing is the inseparable companion of
power of uttering sound.” *
After dilating at considerable length on tk
subject, Bonsdorf says, ‘‘ There remains only on
doubt, which the diligence of an after age may re
move, namely, what openings the tremulous wave
of sound may have reserved for them in the inmos
recesses of the antennee, since these organs are ter.
minated by no open mouth ; or whether these pore
and openings between the joints be concealed, by
which the very tender members connecting the
joints alternately may be struck, for which use thes¢
holes, invisible to the naked eye, seem clearly to b
arranged, and fitted equally for hearing, as thé
smallest bones of the semicircular canals in the
larger animals.
«‘ Nothing more, therefore, is requisite in this case
for confirming this opinion, than to show that they
antennee are active and watchful whenever they
are exposed to hostile and sudden sounds. ,
« J have examined, by many and various experi--
ments for several years, insects of different kinds, |
in which the size of the antenne was different, and
such experiments, provided due care and attentior
are employed, cannot be performed without the
most striking results. In proportion, also, as th
summer season was. agreeable, and the weathe

mild and serene, my success was greater and more
delightful. As all my observations agreed in this
one circumstance, I omit to enumerate them; for
the antenne being erect as soon as they were
put on the alert, they were moved hither and
thither by means of loud sounds, for they disregard-
ed such as were very small. These they may be
said to have drunk in; and if alarmed by new
sounds, they rejoiced when they could effect their
escape as soon as possible, and preserve life and
safety by the most rapid flight. So I have observed
very frequently when the antenne were folded up
in the Lepture, Elateres, Curculiones, Papiliones,
Apes; nay, even the house-fly, as soon as they
were moved and excited by irregular sounds or
‘noise, would erect their antenne, and betake them-
selves to flight, without any other excitement. The
Sphinges again, and Phalene, during the night,
fly about the flowers of the marragon and other lily
plants, emitting an agreeable smell; during the
night, scarcely could a voice be raised then they
would turn round very swiftly, and the antenne
appear to be, as it were, convulsed.
«« T must not pass over in silence, however, that
no evidence more clear could be desired of the sen-
sibility of the antennee to quick sounds, than what
occurred to me last summer in my garden. I ob-
served, in a morning walk, undertaken for the pur-
pose of catching insects on the hazels, that, while

hanging down as if they were asleep; on whi
account I directed a pocket-telescope to the spo

and I was delighted with the opportunity of seei

insects fell down on the ground, as is the habit
those and other weevils. I have never attended t
any proof of hearing in spiders, among which t

separately, seem to add strength to the probabilit,
of our conjecture, namely, that the antenne ar
given to insects for the purpose of perceiving ai
recognising sounds, in a similar manner as the sai
of a ship serve to convert the wind to the use of th
sailor; from which analogy and comparison, I sup!
pose that this name has been assigned to thes
organs of insects.” *
Professor Treviranus says, “I believed I

discovered the organ of hearing in the cockroach,
(Blata Orientalis,) in the form of an opening
covered by a membrane, white, interiorly concave,
and situated at the base of the antennze ; under it
there is a projection from the brain, (the first nerve-
knot or ganglion,) which appears to perform the
office of an auditory nerve. The membrane
was not round, but semicircular, and immediately
bordering on the ring in which the antenne are
fixed: Under it I found a white horny substance,
similar to that which covers the inner crustaceous
envelope of the head. The projections of the brain
appeared to give off nerves to the antennee on each
side ; but I could not determine whether it spread
out over the membrane, which I am inclined to
consider the organ of hearing, as I could not other-
wise conceive of its functions.
The antenne of butterflies terminate in a clubbed
tip, in which there are not muscles for producing
motion, as in the body of these organs, but half a
liquid substance filling the cavity. In the Alder-
man Butterfly, (Ammiralis Atalanta,) I found this
substance intermixed with membranous ‘matter,
resembling in some degree the substance found in
the auditory sacs of the frog, the calcareous portions
being less than in the latter. I think it exceed-
ingly probable that the clubs of the antenne are
the seat of the sense of hearing.” *

METHOD OF COLLECTING BUTTERFLIES
SPHINGES, AND MOTHS.
A.most every country on the globe is inhabite
by numerous species of lepidopterous insects. The
are habited in more splendid attire as we approac
the Tropics.
The localities of the lepidoptera are sneienall
varied ; some inhabit open fields, others are to h
found in the recesses of woods, lanes, and at th
bottom of hedges. But by far the best way td
make a collection of this order of insects is, to pros
cure them either in the larva or pupa state ; and, i
in the former condition, they must be fed on their
natural vegetable diet till they have attained their
full size, and changed into the pupa condition. In>
this state they must be carefully kept till they trans
form into the perfect or imago state. By this means)
they are likely to be more perfect than when take
by the net or other means, as the scales or dust”
which invests their wings is very easily removedj”
which renders the insect imperfect, and has a ten
dency to destroy its beauty.
To procure the pups or larvee of lepidopterous
METHOD OF COLLECTING, &c. 193
insects, the collector must beat the branches of trees
into his folding gauze net, as also hedges, nettles,
Hand other plants, on which these larve feed, or
fto which many of the pupe are suspended by the
tail.
In searching for moths which fly by night, the
London collectors have a lantern constructed with
a concave back, and provided with a reflector be-
hind. This lantern is fastened round the body of
the lepidopterist, about the region of the stomach,
by means of a belt. The fly net should be held
#open in front by the collector, when all those noe-
#turnal flying moths will be entrapped which come
Bwithin the influence of the light, to which they are
Hnaturally attracted. In hot and close summer
evenings, if a candle is placed on the table of a
#summer house, or in other rooms, with the windows
#open, it will be found that many of the night
flying lepidoptera will be thereby attracted.
When taking lepidopterous insects by means of
forceps, they should be as widely expanded as pos-
sible, and the insect should be approached with
great caution. When the entomologist has ap-
proached sufficiently near, the instrument should
be quickly closed on the animal, including the leaf
on which it is settled. When the prey is secured,
a gentle pressure with the finger and thumb is ap-
plied to the thorax below the wings, which soon

Mr Haworth, in the “ Lepidoptera Britannica,”
in mentioning the tenacity of life in the Bomby
Cossus, or Goat Moth, states, that “the usual wa

methods of suffocation by tobacco or sulphur, e
equally inefficacious, unless continued for a grea
number of hours than is proper for the preservatic
of the specimens. Another method now in practi
is better, and however fraught with cruelty it me
appear to the inexperienced collector, is the greate
piece of comparative mercy that can, in this cas
be administered. When the larger moths must
killed, destroy them at once by the insertion of ¢
strong, red-hot needle into their thickest parts, bes
ginning at the front of the thorax. If this be pros
perly done, instead of lingering through several days)
they are dead in a moment. It appears to me;
however, that insects being animals of cold ané
sluggish juices, are not so susceptible of the sensa.
tions we call pain, as those which enjoy a warme}
temperature of body, and a swifter circulation &
the fluids. To the philosophic mind, it is self
evident that they have not such acute organs 0

whose juices are endowed with a quicker motion)
and possess a constant, regular, and genial warmth

such as young mice, or the naked young of birds.
If any of these have the misfortune to lose their
eads or limbs from force, speedy death is the cer-
tain consequence ; but insects under similar cir-
feumstances, it is well known, are capable of sur-
viving a considerable time.”
¥~ Butterflies are soon killed by passing a pin
#through the thorax ; but probably the safest way
fis to adopt: Mr Haworth’s plan, of making their in-
fstant death certain. The pin passed through the
horax of small moths, generally proves almost in-
fstantly fatal to them.
But though nipping the breast will kill many
| small lepidoptera, the larger ones will live long after
pit. “ To despatch these effectually,” say Kirby
and Spence, “ you will find the following apparatus
very convenient :— Fix in a small tin saucepan,
Iled with boiling water, a tin tube consisting of
two pieces that fit into each other ; cover the mouth
of the lower one with a piece of gauze or canvass,
and place your insects upon it ; then fix the upper
one over it, and eover also the mouth of this with
gauze, &c., and the steam from the boiling water
will effectually kill your insects without injuring
their plumage. There is another more simple mode
of doing this ; the apparatus for which may be met
‘with every where. Fix a piece or two of elder or
willow, or any soft wood, with the bark on, across
the bottom of a mug, and on this stick your im-
196 METHOD OF COLLECTING
paled insects, invert the mug in a deep basin, ir
which pour boiling water till it is covered, holdit
it down with a knife, &c., that the expansion of t.
included air may not overturn it. In two minut
or less, all the insects will be found dead, and n
at all wetted. Ifthe sticks do not exactly fit, th
may be wedged in with a piece of cork. Profess
Peck, who used to put minute insects into the he
low of a quill, stopped with a piece of wood mi
to fit, killed them instantaneously by holding
over the flame of a candle.” *
When the insects are killed, the next thing is
prepare them for being placed in the cabinet. T

plied with entomological pins, called short white
The pin should be pierced through the middle
the thorax, forcing it sufficiently through, so thé

insect, to look well, should be nearly close to the}
paper, but at such a distance as the legs do not}
touch the bottom, as they are thereby liable to
broken. _
Some of the continental collectors have the inse
forced up to nearly the head of the pin, so that the
may examine it with a microscope without rem¢
ving the glass lid. This, however, is liable to th

BUTTERFLIES, SPHINGES, AND MOTHS. 197
bjection, that the pin is very liable to be bent in
ushing it into the cork, and the insect does not
ook nearly so well as when near the paper.
The best method of arranging lepidopterous, or
deed other insects, is to arrange them in columns,
ith the generic name at the head of each column,
nd the specific name affixed to each species, or in
fa line with the insect to its right. The lines ought
gto be ruled with a black lead pencil, by which an
falteration can easily be made without destroying
he whole of the paper. Males and females should
placed together if they can be had; and if pos
ible two specimens of each, for the purpose of
xhibiting both the upper and under side. If the
nsect is subject to variety, these should also be
rocured, as these are very useful in elucidating
ecies. Besides the generic and specific names,
he country should also be marked, as well as the
particular locality of the specimens preserved.
OF SETTING LEPIDOPTERA.
The wings of lepidopterous insects should be ad-
fjusted with great nicety and uniformity, otherwise
hey never look well.
The larger insects of this order are set by braces
hiefly. A single one should in the first place be
198 METHOD OF COLLECTING
introduced under the wing, near the thorax, a
shown in the following figure, 7
and a longer brace extending over the wings, as |
AA. These should not bear upon the wings, but
ready to rest gently on them, when required. T
wings are now elevated to their proper position
the setting needle, and other braces are used as necé
sity dictates, in the manner represented in the abo
figure. The feet and antenne are extended a
kept in their places by means of pins ; in whi
operation small braces are also occasionally used.
The French entomologists set butterflies, moths
and sphinges, on a piece of soft wood, in whiél}.
BUTTERFLIES, SPHINGES, AND MOTHS. 199
ey have excavated a groove for the reception of
he body, as deep as the insertion of the wings.
They are otherwise preserved as above directed.
In the larger butterflies, moths, and sphinges,
the abdomen should be perforated, its contents ex-
racted, and then stuffed with fine cotton, after
having been washed internally with the solution .
of corrosive sublimate. Indeed, the cotton should
also be rubbed with the arsenical soap before being
introduced, as these insects are particularly liable
to the attack of smaller insects, such as the mite.
Several of the moth tribe are extremely liable to
change their colour some time after they have been
placed in a cabinet. This change is frequently oc-
casioned by an oily matter which is common to
many of them. This first makes its appearance in
small spots on the body, but soon spreads itself
over the abdomen, thorax, and wings ; and ends in
a total obliteration of all the beautiful markings.
A method which has been sometimes successfully
adopted, is to sprinkle all the wings with powdered
chalk, and holding a heated iron over it ; the chalk
absorbs the grease, and may then be blown off by
means of a pair of small bellows. Another way of
applying the chalk, and perhaps the better of the
two, is to throw some powdered chalk on the face
of a heated iron, and then put it into a piece of
linen cloth, and apply it to the body of the insect ;
200 METHOD OF COLLECTING
the heat of the iron will soften the grease, and the
chalk will absorb it. &
Another method is to hold a heated iron over)
the insects for a few minutes, and then to wash
the spotted or greasy places with ox gall and wate i
applied with a camel-hair pencil, and afterwards:
wash it with pure water, and dry it by an applica—
tion of bloating paper, and when perfectly 4
imbue it with the solution of corrosive sublimate.
But grease seldom appears where the contents of
the abdomen have been removed.
It is most difficult, if not nearly impracticable,
to set many of the smaller moths without destroy-
ing the characters of their wings; and the trunks
of many of them are so small that they are not
even the breadth of a pin. The only method there-
fore of preserving these is by gumming them on @
card, and keeping their wings expanded by means
of the gum. This must be applied with a camel-f
hair pencil. If the collector has two specimens,
one should be set with expanded wings, and the
other in the state while at rest. These small in-f
sects should be placed on dark coloured or blackif
cards, if they are themselves pale; and if dark,
they should be fixed on white cards. t

*# The drawers of the cabinet should be about fif-
een inches in length, eighteen in breadth, and two
nches deep. There should be a layer of cork of about

and a piece of paper pasted on the top.~. The cork
pught to be of the best quality, and free from cracks
and knots. Each drawer should have a lid of glass;

air, and prevents dust.

purchase the cork of a corkcutter, ready prepared ;

(prepare it himself. In this case it should be cut

The stripes should be fixed in a vice, and cut

which eat into and consume their bodies. Cabinets —

method. As soon as the operation is properly per-
formed, the depredating insect perceives that the
prepared specimen is no longer food for it, and will
for ever cease to attack it; but then every part
must have received the poison, otherwise those
parts where the poison has not reached will still be
exposed to the enemy, and he will pass unhurt
over the poisoned parts till he arrives at that part
of your specimen which is still wholesome food for
him. Now, the difficulty lies in applying. the
solution to very minute specimens without injuring
their appearance; and all that can be said is, to
recommend unwearied exertion, which is sure to
be attended with great skill, and great skill will
insure surprising success. I myself have attended
to the preservation of insects with the assiduity
“which Horace recommends to poets :—‘* Nocturna
versate manu, versate diurna.’ The result has
been astonishing success, and a perfect conviction
that there is no absolute and lasting safety for pre-
pared specimens in zoology from the depredations
of insects, except by poisoning every part of them
with a solution of corrosive sublimate in alcohol.
«‘ The tight boxes, and aromatic atmospheres, will
certainly do a great deal, but they are liable to
fail, for this obvious reason, viz. that they do not
render for ever absolutely baneful and abhorrent
to the depredator, that which in itself is nutritious
and grateful to him. In an evil hour, through

METHOD OF TRANSPORTING INSECTS.
The plan described by Levaillant in his Travel
in Africa, for the preservation of his.entomological
collections, is the following :—Boxes or-chests care-
fully made of light wood, of a convenient portable
size, are provided with partitions and moveable
shelves, each consisting of a simple, board ;, these —
are fitted, at the distance of two inches one from ~
another, in grooves. in the sides of the box, in
which they are made to slide with accuracy and
facility, and are therefore removable at pleasure:
OF LEPIDOPTEROUS INSECTS. 209
These boards or shelves have necessarily the exact
dimensions of the ends of the chest, and are placed
in a vertical position ; a small vacancy is preserved
between their lower extremity and the floor, and
4 any Object detached by accident falls to the bottom
without causing farther injury.. Each board or
4 shelf, lined with cork or soft wood, supplies, in
some measure, the place of a cabinet drawer.
When taken out: of the box and placed on a table,
it rests securely and affords a plain surface, upon
which insects may be fixed, or examined with per-
] fect ease and security. It is returned into the box
in an instant, which, if carefully made, when
closed, secures most effectually the contents. One
large box may conveniently contain fourteen boards,
| answering the purpose of as many drawers; and,
being eighteen inches square, they are of a manage-
able size. Dr Horsfield found these boxes most
admirably adapted to his entomological pursuits
while in Java, and preferred those made of light
wood. He says, that when he commenced packing
for. transportation, “ boxes according to Levail-
lant’s plan, were therefore provided of more sub-
stantial material than those employed in travelling,
in proportion to the increase of the collection. The
wood of the Bombax pentandrum was employed
for lining the boards and securing the pins ; and I
ascribed to an acquaintance with the peculiar pro-
perty of this wood, which renders it an effectual

SETTING, AND PRESERVING BUTTER-
FLIES, SPHINGES, AND MOTHS.
THE ENTOMOLOGICAL OR FLY NET.
Tuts net, which is figured above, is similar ‘in
construction to the bat fowling-net, and is either
made of close green gauze or open muslin. It is
sometimes white, which is not so useful as green,
although the former is best adapted for minute
moths, being more easily seen on it. The rods
ought to be made of beech or hickory ; holly and
hazel will also answer the purpose. They should
be from five to six feet in length, made quite round
and smooth, and gradually tapering to a point.
The cross-piece should be made of cane, and fitted
into a ferrule of an angulated form. The rod should
be divided into three or four pieces, so that it may
be carried conveniently in the pocket; a ferrule
should be riveted on each joint at the upper part ;
_ thus prevent them from falling to pieces.
212 INSTRUMENTS USED IN COLLECTING, &c.
and each joint should be provided with a notch or |
check, so as to prevent the upper part from warping. —
Great care ought to be taken in fitting the joints to
the brass tubes, so that they may fit exactly, an d |
THE FOLDING NET.
This net must be bound round with a broad |
welting, doubled, for receiving the side rods. At
the top there must be a piece of shamois leather, ©
for the purpose of acting as a hinge, which must be |
sewed round the welting, divided and attached in |

slipping ; at the lower side there should be about ~
four inches of gauze turned up, so as to form a bag ;~
there. ought to be strings attached, so as to pass”
through a staple for drawing the net tight on each
side.
When this instrument is used, the handles or
rods are to be taken one in each hand, and with
this lepidopterous insects may be taken during thew
flight ; and this is.performed by opening and shut- —
ting the net, and securing, the insects between: the
folds.. It may also be used for) collecting. cater-|
pillars: When used for this purpose, the lepi —
dopterist must expand it under the trees, bushes, or |
plants, which they inhabit, and. beat the branches
with a stick, and the caterpillars will naturally, fall |
on the net.

THE HOOP NET.
This hoop net consists of a strong brass wire
hoop, from nine inches to a foot in diameter, with a
socket for receiving the end of a walking stick or
rod, which the lepidopterist should always carry
along with him. Some are made with a screw, for
greater security. To this ring is attached a bag
of net, gauze, or muslin, about a foot.in depth.
«* The French collectors,” say Messrs Kirby and
Spens, * “use a net of this kind, in which the
hoop is formed of two semicircular pieces of iron or
brass wire, hooked together at one end, and at the
other made to lap over the corresponding piece, and
pierced to receive the screw at the end of your
stick. When not employed they double the hoop.
and conceal it under the rest ; they fix to it amus-
lin bag of two feet long. This net is made to serve
various purposes. With it they catch Lepidoptera
and other flying insects ; and an adroit collector, by
givingit a certain twist, completely closes the mouth,

so as to prevent the escape of his captives. . Fixed
to a very long pole, (Mr Haworth says it should be:
twenty or thirty feet long,) it is the best net for the:
Purple Emperor Butterfly,” described at page 156,
volume first of this work.*
MACLEAN’S ELASTIC NET.
This net is constructed of two stout pieces o
cane, split and connected by a joint at each end,
also by a rod which lies between them, “ in)
which a pully is fixed ; through this a cord fas
ened to the canes passes ; a long cane with a fer
rule receives the lower end of the rod, and forms a)
handle ; and to the canes is fastened a net of green:
gauze.” The handle is taken in the right hand)
and the string in the left ; when the latter is pulled,
the canes bend till they form a hoop, and the net.
appended to them is open ; when insects are within
it the cord is relaxed, and the canes become straight.
Close the mouth of the net, and secure the insects .
These are kept close by the left hand, and the pre
is disabled with the right.

ENTOMOLOGICAL FORCEPS.
The forceps is a very useful instrument for col-
lecting day-flying lepidopterous insects.
Some of these are formed with octagonal leaves,
and others circular or oval; they ought to be five
or six inches in diameter, and covered with muslin
or green gauze, or very fine catgut, the meshes of
which ought to allow the head of a lace pin to pass
through it. The joint of the handle should be
placed nearer the rings for the finger and thumb,
than to the leaves of the instrument, or it will not
open well. The handles may be made of iron, but
the hoop should always be of brass, to prevent its
rusting, or, if made of iron, it ought to be painted.
The objection to the leaves of forceps being round
is, that when the insect. wished to be seized is
perched upon a wall, or other vertical situations,
they cannot be applied with such certainty of se-
curing the object.
216 INSTRUMENTS USED IN COLLECTING, &c.
The entomological forceps made use of in Ge
many are not only longer in the handles, but al
larger in the leaves. The leaves are generally from
ten to twelve inches in diameter.

boxes should be numbered ina small memorandum

of taking small moths, which are difficult to be se-
cured in the open air, from their smallness, and also
the danger of destroying the farina of their wings.
COLLECTING PHIAL.
For the smaller species of butterflies and moths, a
small wide-mouthed phial will be found extremely
useful to the collector. In the cork should be in-
serted a flattened tin tube, into which a piece of
wood should be neatly fitted. By putting the in-
sects through this tube, there is no likelihood of
those which are already within the phial escaping.
POCKET LARV# BOX.
This is simply a small chip-box, with an aper-
ture at top and bottom, and covered with fine open
muslin, for the admission of air. Care ought to be
taken to insert into the box a portion of the leaves

less likely to remove the ree! powder from the”

A DIGGER.
This instrument is made of steel or iron, some-
what about six. inches in length, and fixed into a
wooden handle. It is used for collecting the pupee
of lepidopterous insects, which lie concealed at the
roots of trees and bottoms of hedges. It is also used
for stripping off the bark from trees, where the larva
of many rare insects are to be found ; it ought to be
arrow-pointed.

SETTING NEEDLE.
This instrument is fixed to the stalk of a common.
hair pencil, and is used for extending the parts of
insects, such as their limbs, antenne, wings, &c.
On the opposite end of the stick there ought to he a
hair pencil, for the purpose of removing any dust
'which may fall upon them.
=
This is another kind of Setting Needle, the use
of which will be obvious.
PINS.
The pins used for insects are the small lace kind,
and made very fine for the express purpose; they
ought to be well tinned, to prevent the juices of
the insect from acting on them, and thus producing
verdigris, which destroys the insects.
SETTING BOARDS.
These consist simply of convenient sized thin
deal boards, and covered with a thin layer of cork ;
which ought to be perfectly level on the surface, and
covered with white paper.

“BRACES.
These are small slips of card, which are mad
use of for confining the wings of butterflies, sphinges
and moths, while inthe act of drying.
STORE BOXES.
These should not exceed a foot square in ‘size ;
both top and bottom being about two inches and
half in depth ; and made on the same plan as back-
gammon boards. The inside should be lined with
cork, covered with paper.

THE BREEDING CAGE.

of lepidopterous insects asothey are hatched. If
BUTTERFLIES, SPHINGES, AND MOTHS. 22]
ought to be made of hard wood, having its sides
and front covered with gauze or fine muslin. Inthe
#inside is affixed a box or tube for the reception of
a small phial for inserting plants, on which’ the
caterpillars are accustomed to feed, which it is in-
tended to rear. Breeding cages may be made of
any dimensions ; but the most convenient size is
about a foot in height, eight inches in breadth, and
from four to five in depth. One species of cater-
pillar only ought to be introduced at a time, as
many of these devour each other.
A quantity of earth, mixed with a little sand,
of about two inches in depth, should be placed at
the bottom of each box. The mould should be of a
fine vegetable kind, if possible, which does not so
easily dry and consolidate as clayey soil. The
cages should be placed in some cool place, away
from the influence of the sun, as many species pass
to the pupa condition, remain in that state, and
transform into the perfect insect under the surface
of the earth. Consequently, if the earth is dry
and hard, they will be unable to burst from their
confinement.
«* Those who endeavour to rear the Death’s Head
Hawk Moth, often fail after the insect has passed
into a chrysalis state. I have been informed,” says
Mr L. W. Clarke, “ by a person who has several
times bred them, that his method is to moisten the
chrysalis every morning with warm water, and then
"222 INSTRUMENTS USED IN COLLECTING, &c.
place it in the breeding cage, near the fire, by wh
means the fluids of the body are preserved, and
- ease is not too strong for the perfect insect to pe
‘trate. “He also says, that if they be placed in
_ bark stove with plants, and covered with the e
: they will not perish, as is the case with those gene
rally exposed to the temperature of our. climate.”
