TO T, ROMEYN BECK, M.D, LL.D,

SIR:

Tuere is more than one reason why the concluding divisions of the
present work, undertaken to explore and illustrate the natural history
of the State of New-York, and conducted under legislative patronage,
should be dedicated to you. You were among the first to foster the
enterprise, and remained its consistent advocate in times when adverse
circumstances seemed to jeopardize its continuance : much more than
this, your whole life has been assiduously engaged in promoting the
advance of science and the spread of popular education, and the
published results of your scientific and literary labors may be referred
to as reflecting an honor upon your native State. Would that the
merits of the present volume were such as to render it more worthy

its dedication.

PREFACE.

1 wave not attempted, in the preparation of this work, to place before my
readers an account of all the rare and newly discovered insects of New-
York and New-England, but have confined myself to those which are most
common and widely distributed. The rare and the local possess an interest
in the eyes of the learned ; but those which are daily met with in the fields
and in our walks, are the ones our interests demand us to know: the former
do neither harm nor good; but a familiar acquaintance with the forms and
habits of the common and widely spread, is an indispensable preliminary
towards enabling the husbandman to take advantage of the services they
may be made to render him, or to protect his premises and the fruits of his
labor from the depredations of noxious broods. This view has mainly con-
trolled our undertaking : as the work is designed for those who are supposed
to be mere beginners in entomology, and perhaps intend to prosecute the
study no farther than practical results will warrant, it was thought fit to
restrict the field of investigation to such insects as are sufficiently numerous
to interfere in some way with the prosperity or comforts of the dwellers in
this northern portion of our country.

One part of my labor has been to collect materials in the field, and an-
other to collect them from the researches of others, the latter item con-
stituting doubtlessly the largest and most valuable portion of the entire
work ; but it is confidently believed that naturalists and authors who have
contributed largely to the common stock of entomological knowledge, and
thereby earned and received a high and enduring reputation, will not be
disposed to object to the diffusion of information fraught with such great
consequence to the welfare of community. These distinguished investigators
are honored by their discoveries; but their discoveries require to be made
known to all the world, to the end that their results may redound to the
common good of the human family.

iv 4 *% * ‘PREFACE. = a ‘

After saying thus much in general, it is scarcely necessary to add that
this work is designed to disseminate the thiormatidp collected from various
periodicals in which it was first gathered, and from expensive books of the
day in which a large amount is almost inaccessibly stored up, but is not
expected to add much to the materials of knowledge already accumulated.

We have been poorly supplied with the means of promoting the study of
entomology in this country, notwithstanding we have among us such men
as the Leconte’s elder and younger, who both stand in the first rank of
entomologists; but it is unfortunate that their classical works are mostly
confined to the libraries of the learned.

I have made the freest use of Dr. Hanais’s excellent and practical works ;
and have also been very much assisted by our distinguished entomologist,
Dr. Asa Frren of Salem, Washington county, N.Y. rear

I have occasion also to acknowledge a further indebtedness to Mr. Hat-
peman of Columbia (Pennsylvania), who enjoys a European reputation as a
naturalist, for several valuable notes on various insects; and could his as-
sistance have been still farther procured, the value of my work would un-
doubtedly have been greatly enhanced.

I have figured such insects as I have seen, and know to belong to New-
York and New-England; but I have not seen them in all their states, and
am therefore frequently indebted to others for the figures given of the larva
and pupa stages. Some are copied from Ansorr & Ssirn’s work on the in-
sects of Georgia, and some from other works of like kind. I have figured
very few foreign species, and these have had some’ special purpose in view.

The figures have been drawn from specimens of the insects themselves,
by E. Exons junior, and are faithful and accurate portraits of the indivi-
duals from which they were taken. It is difficult, however, to secure a
finished and uniform coloring, especially for so large an edition as three
thousand copies.

I do not deem it necessary to point out the faults of this volume ; for the
keen-sighted, and those who are disposed to look after them, will find them
with little trouble. I am persuaded, however, that the general reader, as
well as the student, will find in it many valuable records. E. EMMONS.

INSECTS OF NEW-YORK.

CHAPTER I,

GENERAL CONSIDERATIONS.

Tue common idea of an insect is, probably, sufficiently exact for all practical purposes ;
yet it seems proper that the scientific idea should be expressed : indeed it is always im-
portant to define clearly the limits of all departments of Natural History, by stating in
determinate language the boundaries which confine them. Insects, then, are animals whose
bodies are covered with a coriaceous integument ; and they are divided into three distinct
segments or sections, the head, thorax, and abdomen. The head is provided with two an-
tenn ; the thorax, with six articulated legs; and the abdomen with many rings, and
contains the digestive organs : the sexes are distinct. They have a respiratory, circulatory
and nervous apparatus : the first permeates the whole body; the second consists mainly
of a long vessel extending through the body, and is called a dorsal vessel, from the
position it occupies; the third is a symmetrical arrangement of nervous threads in two
lines, placed upon the abdominal face, and connected by knots or ganglia at every ring of
the body. The breathing is performed through small openings along the sides of the ab-
domen, at every ring : the air admitted permeates the whole system, and acts upon the
fluids as in all animals. The most interesting peculiarities, however, consist in the changes
which the insect undergoes during its stages of growth, which, although the developments
are not more remarkable than in other departments of the animal kingdom, yet differ from
the higher in being stationary for certain periods, during which it performs the functions
of a perfect animal, except indeed that which belongs to the exercise of the sexual or-
gans. These changes are called metamorphoses, and consist of three stages, the worm or
larva, the pupa, and the perfect insect.

. ,
2 GENERAL CONSIDERATIONS.
Insects;-as defined in the foregoing paragraph, are still very to other
classes of anignals ; thus they resemble the Myriapodes in the annular or structure,

and in the possession of two antennw, but differ from them by the division of their bodies |
into three segments, while the Myriapodes are composed of many rings, to each of which
there is provided a pair of legs, as in the family of animals called Centipedes. They re-
semble the spiders, or Arachnidw, somewhat in the division of the body, but the head in
spiders is soldered to the thorax : they are also destitute of antennw ; the nervous system
is condensed into fewer central ganglia, and sometimes their respiration is analogous to
the pulmonary, the air being received into sacs or bags. They resemble the Crustacea in a
few points, but differ essentially from them in the character of the respiratory apparatus,
inasmuch as the Crustacea are provided with organs analogous to the gills of fishes. The
resemblance which insects bear to the worms, Annelides, is the annulated structure : those
worms have neither antennw nor feet, and, as to sex, they are mostly hermaphrodites. In
addition to the foregoing, I may add, none of the classes have wings but insects, and their
metamorphoses are of a different character, consisting mainly of a casting of the integu-
ments as in the crab and lobster.

All insects are oviparous, or spring from an egg laid before the birth of the individual.
A few examples are known where the egg is retained in the body, and there hatched.
These eggs are often carefully concealed, and hence are diseovered with difficulty : it is
owing to this circumstance that they multiply to an injurious extent, and are often capable
of devastating extensive territories. They are, however, generally laid upon the bodies
which are to provide the food for the young : those which subsist upon herbaceous plants,
are found upon or near the foliage ; those which feed upon wood are deposited in holes,
or in cracks and crevices of trees, into which the young animal immediately begins to
penetrate ; or, which is equally bad, the egg is deposited in the rudiments of the fruit, and
will be ready to devour it when it is mature.

Insects are extremely prolific, but the different species vary exceedingly. According to
a statement in the Naturalist’s Library, a certain large fly (Mesembrina meridiena) lays only
two eggs ; while the female white ant lays probably not fewer than forty or fifty millions
in a year, which are extruded at the rate of sixty in a minute when engaged in the act*.
This statement embraces the extremes. Others are known to lay, as the queen bee for
exam y thousand ; female wasp, thirty thousand, though generally only from two to
three nd. The eggs of the wheat fly are not very numerous, and probably less than
one hundred ; yet even in that small number the increase will be sufficient to secure the
destruction of the wheatfields in a large district. But many insects produce several broods
in a season, and some of the most prolific produce several generations of young, consisting
mainly of females, which are capable of laying eggs as soon as they have reached a stage

“—_— GENERAL CONSIDERATIONS. 3
of full evelopment But the law of increase seems to rest upon the supply of food : where
this is sure and constant, the increase is much greater than where it is precarious or un-

certain ; thus those insects which subsist on animal food are comparatively limited, while
the vegetable feeders are more numerous : thiS is in keeping with the harmony of nature,
and the original arrangements of the Creator.

The eggs of insects are made up, essentially, of the same parts as the egg of vertebrated
animals. It consists of a yolk, with its germinal dise and germinal spot, which seem really
to be nothing else than a cell with its nucleolus. The yolk is enveloped in a proper mem-
brane ; and in order to defend and protect it, it is supplied with a hard outside envelope,
analogous to the eggshell of the common fowl; but the shell, the white, and its tough
membrane, are not essential parts in the constitution of the egg.

The eggs of insects, like all other eggs, obey the law of temperature. The young are
hatched at an earlier day if the temperature is increased, and the hatching is retarded in a
' medium of low temperature. It therefore happens that man is often a gainer in consequence
of the warmth of spring, which brings forward insect life at an early day, only to perish
by the frosts which soon sueeeed. The eggs of insects are endued with the power to resist,
or rather withstand, wide variations of temperature. It is evident that they sustain all the
ordinary changes of the climate, and that it often happens that they are exposed to a
temperature equal to 20° below zero. The ability to withstand either extreme of tempera-
ture depends upon the conditions of the egg : if it has progressed considerably towards
- the development of an embryo, its power to withstand those extreme changes is diminished.
The pupa resists but feebly those changes when it first assumes this state; but when it
has nearly reached the period of completing its metamorphosis, it is surprising that it can
resist a high degree of heat. I exposed the pupe of numerous silkworms, enclosed in a
bottle, to 212°, without injuring them. I was surprised to find, not many days afterwards,
that hundreds of millers of both sexes had escaped from their cocoons. The warmth of the
sun, together with its light, is sufficient to destroy the vitality of the pupa when it first
assumes that state ; but the eggs of insects require air, or oxygen, as much as the perfect
animal : when enclosed in a vacuum, they lose their vitality. Oxygen is essential to the
development of the embryo, and hence the outer covering must admit its passage.

The eggs of some insects seem to grow : they increase in size, probably by the absorption
of moisture from the atmosphere, or from the surface upon which they are laid.

The covering of eggs varies exceedingly : in some it is beautifully sculptured ; in others
it is smooth and shining. These different characters, if they could be fully delineated,
would constitute important marks for the discrimination of species, for it is probable that
they differ in the species to which they belong.

The most remarkable fact in the history of insects, is their metamorphosis. The egg, as
has been observed already, is similar to the eggs produced by other classes of animals ; but
it never gives birth to a perfect insect, the immediate product of the egg being really as

.

4 GENERAL CONSIDERATIONS.

unlike thé perfect insect as possible ; for what can be more unlike than the caterpillar and
butterfly ? How disgusting the one, as it crawls like a reptile; and how beautiful the
other, as it flits in the air like a bird!

From the egg, the first state in which the insect appears is the larva. This stage of
existence is characterized by the vermiform shape and construction of their bodies ; and
it is a stage which attracts our attention more frequently than that of the insect,
and it is one in which it usually commits a greater amount of injury than in the perfect
stage : it is, too, in this stage that the agriculturist can more effectually exterminate these
his foes. The term /erva is applied generally to the immature butterfly or caterpillar. Grubs
are white, soft-bodied animals, which are immature beetles ; while maggots are immature
flies, or belong to the dipterous order of insects. All, however, are the analogous re-
presentatives of the different orders in the same stage of development, or that stage during
which the insect grows and frequently casts its integuments : it devours immense quanti-
ties of food, and is often very destructive to the foliage of vegetables. When it has reached
its development for the larva stage, it ceases to eat, wraps itself in a mantle, simulates
death, but is really undergoing internal changes preparatory to a higher stage of develop-
ment. In its mantle it casts its old skin, which it presses down into the lower part of its
envelope, and soon appears in a livery peculiar to the pupa stage. The time during which
it is confined to this stage varies with every insect : in some it is brief; in others, it is long.

Insects are composed of thirteen segments, including the head ; but an obscurity often
arises from the consolidation of segments, and often produces thereby a disproportionate .
development of certain parts. The three segments immediately behind the head correspond
to the prothorar, mesotho, ar, and metathoraz of the insect ; and these bear the three pair of
legs, provided the larva possesses legs. These are persistent, and hence are called true legs,
to distinguish them from the abdominal legs, prolegs or props, which are caducous, or are
never transmitted to the perfect insect ; they are peculiar to the larva. The mouth-pieces
or oral organs frequently differ in the different stages also. These are sometimes designed
for suction in the larva, while the perfect insect is provided with jaws for mastication ;
hence, in such cases, the nature of the food is changed : in other cases the provisions for
taking food are the same in both stages.

The larve grow rapidly, as a general fact, insomuch that the whole structure of the
animal it tes provisions subservient to this result : they are provided with strong and
efficient ns of manducation ; their digestive organs are very large rato ; the
function of digestion is rapidly effected, and the consumption of food is in pro-
+ portion to the weight of the body. It is stated that flesh-flies increase two hundred times
their weight in twenty-four hours. Count Daxpoto remarks that the weight of the silk-
worm, when first hatched, is about one-hundredth of a grain, or it requires one hundred
of them to weigh a grain : after the first moulting, one hundred weigh 15 grains ; after
the second, the same number weigh 94 grains ; after the third, their weight is 400 grains ;

GENERAL CONSIDERATIONS. 5

after the fourth, their conjoint weight is 1628 grains ; and after the fifth, when they have
attained a length of three inches, they weigh 9500 grains. These changes of skin, called
moultings, seem designed to accommodate the development of the body to its outer enve-
lope : it is a critical period ; and if any accident happens which interferes with its proper
performance, the animal either perishes, or is left in an enfeebled state, and is unable to
assume the form of the perfect insect. The number of moultings varies with the species,
but is always alike in the same species : the same changes are repeated in each respective-
ly. All these changes are best observed in the silkworm, in which their number is five, and
require thirty days for their complete performance. In some insects the number of moult-
ings extends to nine or ten, while in others it does not exceed three or four. The larva
ceases to eat when it is undergoing this process : an internal change takes place, however,
which greatly favors the casting of its envelope ; it is the absorption of the fat beneath the
outer skin, which becomes shrivelled, while at the same time it gives opportunity for the
expansion of the internal parts. The motions are strange during this period : their bodies
are curiously shaken and contorted, with jerkings of the head and posterior parts of the
abdomen ; these are designed to break up the attachments of the outer skin, and finally
to detach it from the new skin beneath, which is bright, fresh, and moist. A rent is finally
made in the old skin along the back, through which the animal now forces its way, in
which process it is assisted by attaching itself to some point of support : this is managed
so adroitly that the old skin remains whole, except the rent along the back, and so perfect
that it might be mistaken for the perfect larva. The change is not confined to the outer
envelope : the organs of respiration, though extremely delicate, as well as those of diges-
tion, cast off also their membranes, which are ultimately expelled from the body. It is no
wonder, then, that the moulting stage is one of great danger to the larva. This becomes
still more hazardous to the silkworm which is placed in an artificial state, and which is
increased by the numbers that are crowded into a small area. The last change is attended
with circumstances somewhat peculiar. They first seek a suitable retreat, adapted to the
nature of the insect itself; a crevice in the bark of trees, a shelter under the roof of a
building, or a hole in the ground, in which they construct a sort of chamber, which they
line and otherwise prepare in a mode suitable to their necessities. They form habitations
with much skill, and the bestowment of much care, to defend their bodies from the ex-
tremes of temperature, or as a defence from their enemies. Sometimes, as in the dipterous
insects, the old skin is converted into a pupa case, after becoming more rigid and stiff : in
other instances a beautiful case is made, and a robe of silk is laboriously woven from a
single thread, which is formed and spun from the juices of the body.

The silkworm is an admirable example to illustrate the instinctive powers of insects in
perfecting their stages of development. We admire the skill by which it suspends itself in
its case, and the beautiful mancuvres by which it manages to place the band of silk around

its body. The habitation of the pupa is usually called its cocoon ; which term, however, is
more commonly applied to those silken cases or envelopes of which I have been speaking,
and of which we have an example in the silkworm. This is so closely woven that it ex-
cludes water, and is often stiffened by a glutinous matter, by which it preserves its original
form even after the perfect animal has escaped ; it is also farther strengthened by leaves
and pieces of wood, which undoubtedly serve as a better protection from its enemies.
Thus this helpless state is guarded and protected by a system of means which are ealeulated
to secure the existence of the animal in its utterly helpless state ; a state which simulates
death, and which, in its ultimate triumph, resembles the resurrection of the body from the
grave of rea) death.

All insects do not undergo the same changes ; neither are they alike in analogous states.
Thus the caterpillar of our butterflies wraps itself in its mantlé, where it silently under-
goes its change ; but the grasshopper comes from the egg an immature insect, but with the
general form of the perfect animal, and hops about with the rudiments of wings upon its
back. As it grows rapidly, it outgrows its skin, which it frequently casts, like the larva of
the butterfly : its wings continue to grow, and the body to increase ; the partial wings
keep pace with these changes, till at last they are perfected, and the animal has reached
its perfect state without having lost its activity during its period of growth. The grass-
hopper, then, never passes into the inactive pupa state ; and in this its metamorphosis is
similar to bugs, and dissimilar to beetles and caterpillars.

There is another difference in the history of insect life, which is interesting : it is not
the inhabitant of the same medium through life. It may begin its career in the water, and
end it in the air : the musquito is an example. Who has not observed the wiggler in
stagnant water, and in our cisterns? It is the musquito enjoying its water-life to the full.
When the time arrives for its change, it rises to the surface, bursts its mantle, thrusts up
its head and spreads its wings, while with its feet it rests still upon its cast-off mantle, then
rises buoyant from its sinking bark, and flies away in triumph from the element which
gave it birth.

Equally remarkable are the appetites of the insect in its larva and in its perfect state.
Thus the larva, or, as it is usually called, the maggot, sports and feeds upon the putrid
mass ; but the fly, which springs from its mantle, seeks the honey of our table : so various
are the sand manners of insect life. The caterpillar, grub and maggot go through the
three s or undergo 4 complete metamorphosis ; passing through the three periods
which are known as the caterpillar, pupa, and imago.or perfect stage. The last is the only
period which is given them to continue their kind and generations : in many it is transient
as the fleeting day, and seems designed only for fulfilling the law of increase ; which, when
fulfilled, the insect dies.

CHAPTER If.

SKETCH OF THE ANATOMY AND PHYSIOLOGY OF INSECTS. .

Tue parts of the insect which are employed in description are the antenne, the segments,
the wings and nervures, the eyes, the parts forming the mouth, ete.; and these it will be
necessary to describe somewhat at length. The three divisions of the body are marked by
deep incisions, by which the head, thorax and abdomen, or hind-body as it is sometimes
called, are always distinet in the perfect insect ; but in the larva there are only two divi-
sions, the head and body. The middle, or thorax, supports the head and wings. The head is
armed with jaws or mandibles and palpi, and ornamented or surmounted by the antenne,
which, in some insects, are much larger than their bodies, and are made up of many joints
gradually tapering to a point.

The wings of beetles are composed of dissimilar pieces, lying, when at rest, one above
the other. The upper or outer wing is thick, and shaped to the parietes of the abdomen,
being convex above and concave below : it protects the true wing, which is delicate and
studiously folded, and is only elevated in flight, in order to give play to the true wings.
The upper wings are called elytra, to distinguish them from the reticulated wing; they
are also denominated wing-covers or cases, and are often finely sculptured, punctured or
ornamented ; to these the insect frequently owes its beauty ; upon these, too, the fine
colors are impressed, which are often of a splendent hue or lustre. In other orders of in-
sects the four wings are entirely reticulated, or composed of a fine network traversed
longitudinally and obliquely by nervures which branch in the same species in a certain
manner, which, from their constancy, have been employed by systematists to aid in clas-
sifying, and as characteristics of genera. The wings are still farther modified in the Le-
pidoptera ; the network is more compact and close, and is covered with fine seales but
slightly attached, which appear to the unassisted eye like meal of a pearly hue. Butterflies
and moths are provided with this peculiar wing, which, though extremely delicate and
always injured when slightly touched with the finger, yet always appears perfect when
first captured ; showing thereby their power and ability to perform the natural functions
for which they were designed, without sustaining the loss of this delicate substance.

The external covering of insects is quite hard ; it is called integument, or crust, and
supplies the place of the internal skeleton, and is the part to which the muscles are at-
tached. It is somewhat horny, or corneous, but varies considerably in this respect in the
different species : in certain beetles it is hard and inflexible ; while in others, it is soft and
quite flexible. It resembles the true skin of animals in its divisibility into three layers, an
epidermis, a rete mucosum, and a leathery tunic called the corium or dermis, the true skin.
This outer integument is composed chemically of phosphate of lime and magnesia; but,
what is interesting, it is found to contain a peculiar substance, termed chitine, which is
insoluble in potash. Phosphate of iron, albumen, and a peculiar coloring matter, are also
among the substances composing this integument.

The shape of the head is variable, but the spherical form predominates. The integument
forms a kind of box, with an aperture in front, through which the organs of the mouth
may be thrust. The posterior part furnishes a place and attachments for the museles which
move the head upon the thorax. The eyes are Jarge, usually, and oceupy the lateral parts
of the head. The external parts of the head have received different names. The epicranium
is that portion which extends from the eyes backwards. In front of the epicranium, is the
forehead. The c/ypeus is the margin in front above the mouth. Sometimes the whole region
in front of the eyes is called the face. The inferior parts of the box enclosing the head has
also its spaces, which have received distinct names, as gula, or throat, which lies imme-
diately behind the margin of the lower lip, and extends back to the prothorax. The cheeks
are situated upon the sides of the head, from the eyes downwards to the mouth. The an-
tenne are situated between the angle of the mouth and the eyes : they have a subglobose
joint at the base, upon which they move, and which is placed in a kind of socket ; this is
sometimes called a forulus.

The mouth, as may be supposed, is constructed so as to answer the ends designed, and
it is either suctorial or manducatory, masticating : if the food is fluid, it is suetorial; if
solid, it has jaws for mastication. In the mandibulate or masticating, there is perfect free-
dom of motion ; in the suctorial or hanstellate (Aaustellata), the parts are more or less
soldered together, so as to form a tube for the transmission of fluids. The terms Aaustellata
and mendibulata apply, therefore, to two great classes of insects, one of which subsists on
the juices of plants and animals, which they obtain by suction ; the others, the masticating,
subsist on solid substances. Animals destined to obtain food by modes so apparently distinct,
furnish many distinctive characters of importance. The /abrum is the most anterior part
seen from above ; it covers the mouth, and is united by a membranous hinge to the cly-
peus : it is employed in retaining the food in the mouth during mastication ; it is, there-
fore, a true upper lip, but of a variable form. Mastication is performed by the mandibles,
which are two strong jaws that move laterally, and consist of wedge-shaped or triangular
pieces more or less elongated, and placed immediately below the labrum. These organs are
also called upper jaws : they move like the blades of scissors. Their inner edge is fre-

DESCRIPTION OF PARTS. 9

quently dentate or toothed, the teeth being arranged so as to shut within each other. Below
the upper jaw are the feeler jaws, or maxillx ; these also move horizontally : they are
smaller, and, instead of notches, their inner edges are furnished with bristles or hairs ; they
are articulated to the throat by a hinge (cardo), which places them at right angles to the
stipe or stalk, which last is pretty thick and strong at its upper part. Attached to this is
the feeler-bearer, so called because the maxillary palpus is inserted on its outer edge. The
terminal portion of the maxilla is the maxillary lobe, which is frequently toothed at its
extremity. The maxillary palpus is a filiform, jointed process, which always dis‘inguishes
the maxille from the mandibles. The proportion of joints is variable, and in number they
never exceed six. The terminal joint is quite variable in form in the different genera, and
hence becomes an important characteristic. The under lip is called a latium; it antagonizes
the labrum : at its base is the mentum or chin. The anterior part bears the labial palpi :
the terminal portion is the ligu/a, and is often lobed. The labial palpi are jointed, but the
joints never exceed four. The tongue, in the Carabide, is a lining membrane of the under
lip, which protrudes along its anterior angles, or in front : it is obscure among the Coleo-
ptera, but more distinet among the Orthoptera. The mouth designed for suction is not very
dissimilar to the one formed for mastication. The mandibles have undergone mc difications
which are referred to three types, that have received the following appellations : premuscts,
proboscis, and haustellum. The tube is formed by the elongation of the maxilla and accessory
parts : so also it is formed by the mandibles.

The thorax is the section of the insect which lies between the head and abdomen : it
supports the legs. Three principal pieces enter into its composition : the anterior supports
the fore-legs, and is called the prothorar; the next, the mesothorar, which supports the
middle legs and fore-wings; the last, the metathorax, which supports the hind-legs and
hind-wings. The inferior part of the thorax is covered by a plate, called the prosternum by
Burmeister. The scufellum is a triangular piece of integument interposed between the
elytra at their base : sometimes it is concealed by the elytra. Connected with the seutellum
is the frenum, a membrane designed to regulate the quantity of movement belonging to the
elytra : in the Fulgura it consists of cartilaginous elastic rings, which admit of tension and
relaxation. The mesothorax has another important division, called the scapu/e : they assist
in forming the articulating socket of the elytra; they pass down the sides of the second
thoracic segment. The mesothorax has also its spiracle : on the under side of this segment
is placed the mesosternum; it contains the sockets of the middle legs. The metathorax is
the posterior segment of the thorax, which supports the hind-legs and the inferior wings :
it is well developed in the Coleoptera and Orthoptera. The best authorities regard it as
admitting of a division into seven pieces : the dorsal portion is the mefonotum ; it is
quadrangular, and notched in front. The metathorax is separated from the abdomen by a
parietal wall called the metaphragma, and from the mesothorax by the mesephregma. The
lateral portions of the metathorax are provided with horny plates, termed by Kirsy and

{ Acricuttorat Rerorr— Vot. v.] 2

10 DESCRIPTION OF PARTS,

Srexce plewra and peripleura; the latter supports the Aalteres or poisers in dipterous in-
sects, The thorax invariably supports six legs. The wings are sometimes wanting, when
the insect is said to be apterous ; those with two wings are dipterous; and those with four,
tetrapterows. The superior wings are provided with an articulating socket, which is formed
in part by the organ called the scapula : they lie close upon the sternum ; they constitute
the second pripelpal portion of the mesothorax, lying one on each side in front. Another
distinct portion of the mesothorax is the mesosternum : it lies upon the under side, opposite
the mesonotum ; in its area the middle legs are articulated. The mesosternum is not equal-
ly developed in all orders of insects : it is most perfect in the Coleoptera and Orthoptera ;
the dorsal portion has received the name of metanotum, quadrangular in form, and emargi-
nate in front.

The parts supported by the thorax are the wings and legs; and, as has been observed
already, the latter are invariably six in number, and never wanting. The wings are variable
in number, in form and in substance ; and upon the variability in form and substance, the
orders are composed. Thus those with four wings are termed tefrapterous ; those with two,
dipterous; and those with none, apterous. The anterior pair in Tetraptera is attached to the
mesothorax : this pair is also sometimes called the superior pair, while the pair attached
to the metathorax is called the posterior or inferior pair. The pair which is wanting in the
Diptera, is the posterior pair.

It has been said that the wings differ in form and substance. Nature, however, preserves
rigorously the symmetry of parts. In Coleoptera, the anterior wings differ from the posterior
both in substance and form. The substance of the first is leathery, more or less rigid, and
horny : their form is various, but adapted to the dorsum or back of the insect ; while the
posterior are membranous, flexible and elastic, and capable of being folded beneath the
anterior wings. In another order of Tetraptera the wings are similar in form and substance,
and of equal size : these insects have received the name of ewroptera. Where, however,
in tetrapterous insects, the posterior wings differ in size, but preserve the form and sub-
stance of the anterior, the order is called Hymenoptera. Examples of Neuroptera are the
dragon-flies ; of Hymenoptera, the common honey-bee, wasp, ete. In flight, the rigid an-
terior wing of the Coleoptera is of little use : it serves to protect the membranous wing
and abdomen when at rest. Hence it is that the flight of beetles is short, and sustained
evidently with much more labor than that of dragon-flies or honey-bees. The insects whose
wings are fotlr, and covered with seales, are called from this last cireumstance Lepidoptera,

It is proper here to remark, that while there is a great dissimilarity between the anterior
wing of « beetle and that of a dragon-fly, yet we are not to suppose that the difference is
effected by a sudden leap : there is really a gradation in substance. We have insects whose
anterior wings are intermediate in this respect, both in substance and form. Thus the com-
mon grasshopper has an anterior wing which is between leathery and membranous, and is

DESCRIPTION OF PARTS. 11

elongated very frequently beyond the body. This is the characteristic of the order Ortho-
ptera of systematic writers ; and in this order, the wing grows with the body of the insect.
There is another modification of the anterior wing, which seems to arise from an arrest of
development, as the organ acquires searcely half its usual length : this modification has
served to establish the order Hemiptera of authors.

A still more beautiful modification of the wing of the inseet is found in butterflies and
moths. In these the membrane and network, constituting the frame and foundation-work
of the organ, are covered with a mealy substance, or what appears to the unassisted eye as
such. This substance, however, is a scale of a beautiful workmanship, of a variable form
and size in different insects, and in different parts of the wing of the same insect : they
are beautiful objects for the microscope. Rude handling immediately destroys the beauty
of the wing, by detaching these scales, and leaving the membrane beneath naked: and
broken. .

The wing, anatomically considered, is composed of two parts : the nervures, and mem-
brane. The former are likened unto ribs, which start from the anterior angle, and branch
in various ways as they pass to the posterior margin. They give strength to the organ, and
serve an important purpose in supporting and staying the outstretched membrane. The
neryures are not, as might at first be supposed, solid ribs : they are traversed internally by
a spiral vessel and nerve. The membrane is double, although extremely delicate : this
delicacy, however, is no obstacle to the growth of appendages, such as hairs, ete., inasmuch
as it is frequently densely covered with them. The wing, divided by the branching and
anastomosing of the nervures, forms a network more or less fine. The spaces enclosed by
the branches are called cells or areolets ; and being quite constant in form and place, they
are employed in the determination of groups. Three areas are particularly noticed, namely,
the costal, intermediate, and anal areas. The wing has a base, and anterior and posterior
- margins : the first is the part attached to the sternum ; the two others define themselves.
The apex of the wing is the part opposite to the base.

Various views have been expressed by different authors on the analogical relations of the
wings, many of which are certainly very fanciful. M. Avpovurn takes a rational common
sense view of these relations, and regards the wings as organs sui generis, intended for the
exercise of special functions.

Tue Lees. Each segment of the thorax supports a pair of legs. The joint which unites
them with the body is called the cora or hip : it is held in its socket by a ligament. The
motions of the leg are controlled more or less by the form of the coxa. The thigh is the
largest portion of the leg : its form is various; it is cylindrical or flattened, it is straight
or arched. If the insect leaps, the posterior thighs are thick and strong. The legs are also

more or less spinous.
The fidia is the next part of the leg, and forms an angle with the thigh. It is more

slonder than the thigh, and is connected with it by « joint similar to a knee-joint, called
giaglimus (articulation) ; it is so formed that it may be closely applied to the thigh. Spines-
and spurs are also found upon the tibia or shank : whien the spines are short, they are
regarded as teeth. The spurs are articulated with the part, and possess some motion : they
are commonly arranged in pairs at the extremity of each tibia.

The tibia terminates below in the fersus, or foot ; this consists of a series of pieces, more
or less heart-shaped, and never exceeding five in number. The combined motion of these
pieces is considerable, though it is such as belongs to the ginglimus articulation : they are
never of equal length, and the first one is the longest of all. The terminal piece bears a
bifid claw, often dentate or serrate on the edges ; and a spurious claw is frequently found
between the branches. In addition to the forenamed parts, we often find cushions placed
upon the bottom of the foot, which serve as sucking cups, enabling the insect to support
itself in a pendant position. Hairs also clothe the sole.

The forelegs often exhibit a form more or less divergent from the others, and hence serve
an additional purpose in the cconomy of the inseet : they are employed in prehension.
So it is sometimes the case that the hindlegs have a form specially adapted to a particular
purpose, such as the rolling of the ball in which the eggs are enclosed, ete,

The third part of the body of an inseet, which calls for our attention, is the abdomen :
it has no appendage, and in this respect differs from the parts already noticed. Its external
structure is not peculiar ; for, like the other parts, it is composed of a series of horny rings
or segments, which are closely connected together. The rings do not exceed nine in num-
ber : if they appear to be fewer than nine, it may arise from the overlapping of adjacent
ones. A section of the abdomen exhibits a triangular outline. The abdomen itself is united
to the thorax, but not always in the same way : the area of junction is sometimes broad,
or equal to that of the first segment ; in other cases the union is by a short stem, or petiole,
consisting of a trumpet-shaped tube : the abdomen is sessile in the former case, and pe-
tiolated in the latter. The rings or segments are united to each other in two ways : by the
first; the inferior and middle parts are joined or soldered together, leaving the sides and
dorsal portions only free; by the second way, there is no soldering of parts, but the rings
aro supported by overlapping each other, and may slide into each other like the pieces of
a telescope. In the former mode, motion is restricted, while the greatest freedom exists in
the latter. The segments are lined by a membrane, but it is scarcely visible except in the
ease of a gravid female, when it is seen distended like a bag.

The abdomen, being comparatively free, is well fitted ta sustain the function of respira-
tion. To this end, each segment or ring is furnished with an opening for the transmission
of air, which penetrates thence in appropriate vessels throughout the whole body. These
openings are surrounded by rings, and are usually denominated spiracles. As the abdomen
is devoted to digestion, and is also the cavity in which the generative organs are lodged, it

DESCRIPTION OF PARTS. 13

is necessary that it should be well supplied with air or oxygen : hence each segment has
a pair of spiracles, which are capable of inhaling a large amount of this essential element.
The external orifices are often protected by hairs, which shut over them, and thus serve to
exclude foreign matters, while the air permeates freely into the interior of the body.

Besides the digestive organs, and a portion of the respiratory apparatus, the abdomen
e»ntains the genital organs, the piercer and sting of females. The piercer is a flexible jointed
tube, and is used to puncture trees or other bodies for the purpose of depositing the eggs.
It varies in length and form, and is fitted to perform its office according to the instinct of
the animal to which it belongs.

I have now deseribed, in as few words as possible, the most essential external parts of
insects ; those parts which are particularly employed in the description of genera and
species, as well as those used in general classification. From these parts the student will
be able to form a correct notion of the extent of this class of animals; but there are yet
other portions, occupying the interior of the insect’s body, which are important for us to
study, inasmuch as they will yield information in regard to the economy of this interesting
class which will be of essential service. I refer to the digestive, circulatory, and nervous
systems. If the external forms of insects are curious and interesting, the student will find
that the apparatus for carrying on the foregoing functions is still more so. There is espe-
cially one curious fact particularly worthy of notice in relation to the digestive apparatus :
it is this, that the secretory organs are reduced to the simplest form, that of tubes; from
which we learn that nature requires no special form of instrument for the performance of
a given function.

All the essentials of a digestive apparatus, which belong to the higher classes of animals,
are found in the insect. Some interesting differences, it is true, exist ; still when it is con-
sidered that the food of insects does not really differ from that of other animals, we may
of course expect to find the digestive organs essentially the same in kind. As insects subsist
upon various kinds of food, some upon vegetables, others upon the elaborated juices of
animals or upon flesh, so we find similar variations in the form and proportion of the organs
as exist among the higher animals. The vegetable feeder has a larger and more capacious
digestive apparatus than the carnivorous insect, nature always adapting her means to the
end.

The function of digestion in insects, as in all other animals, is performed through the
instrumentality of an alimentary canal. Our first object will be to describe this apparatus:
The function itself involves the existence of two kinds of apparatus : the parts through
which the food must pass; and the parts which supply the special fluids essential to effect
certain changes in the food before it can become aliment or nutrient matter. Beginning
with the description of, the first kind of apparatus, namely, the organ or organs through
which the food passes during the process of digestion, we may regard this apparatus as a

.
canal open at each extremity, with an enlargement or dilatation more or less in its central
portion ; whence it is dit ,and becomes tubular and folded repeatedly upon itself,
increasing thereby in until in some insthnces it is many times the length of the body.

Differént portions of this canal have received different appellations, as is highly proper,
from the fact that certain of its parts perform functions of a modified character, although
all contributing to one general result. In this division of parts, comparative anatomists
have employed the same names that have long been in use in the anatomy of the higher
animals, as the following enumeration will show, to wit: the pharynx, asophagus, crop,
gizzard, stomach or chylific ventricle, small intestines, caecum and rectum.

The pharynx is the anterior portion or beginning of the canal. The cavity of the mouth
opens into it, and it is an aperture more or less enlarged : it is, however, better developed
in those insects which masticate their food, the mandibulated class. Indeed it is regarded
as having no existence except in this class; for in the suctorial insect, the next part, or
esophagus, is in direct continuity with the haustella or sucking tube, which is connected
with it by two distinet tubes.

- The esophagus, commonly known as the guélet, is a tube connecting the pharynx with
neinhat first enlargement of the intestinal canal. It passes directly through the thorax
and constricted part of the insect, terminating in the abdomen in the erop. It is variable
in length : it may form one-half the length of the canal, while in other instances it is less
than one-sixth of such length. It has a peculiarity which has already been alluded to : its
bifurcation anteriorly in the lepidoptera, each spiral sucking tube extending its branch to
it just behind the head.

. The esophagus is connected in the first place with the crop, an enlargement having a
close analogy in position and form with the crop of a bird. It is also called a stomach by
some writers on entomology. It is sometimes placed on a line with the esophagus, when it
appears as a simple enlargement of the tube; in other instances it is placed on one side,
and then appears more like a sac connected with the esophagus by a short canal, and
serving as a kind of reservoir; or, in other words, more analogous to the erop of birds*.
In certain beetles, as the Cicindela, the organ is provided with a glandular apparatus, which
secretes an abundant and active juice to soften and otherwise change the food deposited in
it. In the hemiptera it is remarkably modified in function : it loses its importance as a
depository of food, and becomes a part of a pumping apparatus ; whence it has been called
a sucking stomach. The insect in this case has the power of distending the sac, and thereby

*Tt is proper in this place to notice the fact, that while there are namerons variations in the form and length of
the alimentary canal of insects, there are two modifications that should be particularly spoken of, namely ; the
bot-fly has no opening at all answering to the mouth and pharynx, and hence can take no nourishment; and in the
larva of the wasp and bee, the rectum fs closed, and hence their economy docs not require tlie evacuation of ex.
ecrementitious matter.

DESCRIPTION OF PARTS. 15

rarifying the air in its interior ; in consequence of which, fluids rise in it as in a pump.
We have in this case an instance of a modification of an organ of the simplest kind, by
which, however, the entire function is changed; passing from a digestive function to a
transferring one, or one more immediately subservient to the mouth.

The gizzard is the next organ, and may be distinguished from the crop by its peculiar
apparatus for mastication : its internal surface is studded “ with teeth or spines, or horny
ridges ;” the organ, therefore, is eminently fitted for performing a perfect comminution of
the matters received into it. It completes, in this respect, what has been performed but
imperfectly. It performs a function somewhat analogous to that of rumination in the
herbivora. All the insects which feed upon hard substances, those which might be regarded
as nearly indigestible, are provided with a strong muscular gizzard, furnished with a
masticating apparatus. ;

The stomach, or that part in which we first observe the food reduced to a pulpy mass,
and first exhibiting a chylous appearance, is bounded above by the gizzard, and below by.
a constricted portion of the canal, which receives a bundle of vessels that give it an ana-
logy to the liver of vertebrated animals, and in fact it is strictly the hepatic organ of in-
sects. The stomach is of an oval shape, or an elongated oval : it has been denominated the
chylific ventricle by M. Leon Duvour. Its capacity is considerable : its surface is lined by
a mucous membrane, and it is sometimes studded over with little mucous cysts or bags,
which secrete a solvent fluid similar in composition and use to the gastric fluid of the
higher animals. The organ, in order to inerease the extent of surface, is frequently con-
stricted, and also twisted upon itself, so as to form many circumvolutions, and hence it is
quite variable in shape in the different orders of insects : its inner surface, however, is
always villous.

From the stomach outwards or downward, the canal becomes narrower, or passes along
with a diminished calibre ; but as there are still enlargements or dilatations in its course,
anatomists speak of a duodenum, ileum, cecum, colon and rectum. But this is regarded by
many as an unnecessary multiplication of names, inasmuch as it is extremely difficult to
recognize the parts which are thus designated. The beginning of this part of the canal,
however, is indicated by a constriction and the existence of a sphineter muscle, as well as
by the junction below of the hepatie vessels. The tube is generally short, rarely exceeding
the length of the body :; sometimes it is inflated into an ovoid sae rather abruptly.

In following out the distinction of parts in the intestinal canal, we may recognize the
existence of a colon, or what corresponds to the large intestines of the higher animals, by
the character of the alimentary ball; for the food, after having passed the stomach and
through the narrowed part of the canal posterior to the stomach, loses its viscidity, and
becomes more or less dry and compacted into the form of an excrement, showing by its
condition that the nutrient matter has been extracted from it. Here is also a valve to guard

16 FUNCTION OF DIGESTION.

the passage of the canal, which it closes to prevent the backward movement of the digested
mass. The segment as the ewcum is short, and in direct communication with
the anterior tube ; | cases it seems as if joined laterally to it, and then it has the
appearance of a pouch. Fluids are supposed to be secreted by warty excrescences situated
upon the mucous face of this intestine, designed to uid in the digestive process.

The rectum is that part of the large intestines which terminates the alimentary canal
below : it is always short, and is furnished with a sphineter at its extremity. It is mus-
oular, has thicker walls than the cwcum, and gives shape and form to the excrements.

The function of digestion requires, in addition to the formal tube through which the
parent matter must pass, a supply of certain fluids which shall possess a solvent power
upon the contained mass ; and more than one kind of fluid seems to be necessary. Though
these different fluids agree in use and effect with analogous ones found in the higher ani-
mals, the organs which secrete them have a very different form : indeed, the difference is
so great, that a student whose views of the function of digestion have been obtained solely
from the observation of the organs of a vertebrate animal would not at first recognize the
parts which perform similar functions in insects. ;

The secretory organs, and those which are subservient to digestion, are always tubular
in insects : the gland or parenchyma present in quadrupeds being entirely absent in in-
sects, these organs are reduced to their simplest form. The kinds of tubes taking their
names according to the nature of the fluid secreted, are the salivary, biliery, and urinary.
The salivary apparatus is quite complicated : it consists of tubes, single and double, and
even triple, situated around the esophagus and mouth, and provided with bags that serve
as reservoirs. The tubes open into the mouth or esophagus by two or more exeretory orifices.
The salivary apparatus is most perfect in the haustellata or sucking inseets; the tubes
ascending into the abovenamed cavities in a meandering course, whereby the extent of
secreting surface is much increased.

The operation of salivation is an important preliminary to digestion : mixed with the
food, the saliva serves to soften its consistence, while it also carries along with it much air
which appears to be necessary for some purpose in the economy. The bile is a still more
im t fluid than the saliva : it is secreted in long capillary tubes, more or less flexuose
and folded upon themselves, which connect with the alimentary tube below the stomach,
or just behind the pylorus ; though they sometimes continue farther down, and enter near
the ca#cum. These tubes vary in number : there are usually two, especially in coleoptera,
hemiptera and diptera; but in these orders they are not absolutely uniform, as in the
cerambycidwe there are three, and four in some diptera, while in neuroptera there are six,
and in certain neuropterous groups as many as eight. Where the number of the tubes
varies, however, it operates as a compensation for their length : for example, if the simple
tubes are each five or six times the length of the body, their number is less; but when

FUNCTION OF DIGESTION. 17

they are short, their number is proportionally increased. Although these hepatic tubes are
generally quite uniform in diameter, there are some deviations from the rule ; but it is
perhaps unnecessary to describe particularly the few modifications that are known to oceur.
The function of these tubes, as has been intimated, is to secrete or prepare a fluid analogous
to bile. They may be recognized in the caterpillar, when the abdomen is opened, by their
position, and by their white vermiform appearance : they float apparently loosely in the
cavity of the abdomen.

Among the secretions mentioned is the urinary, which seems to be far less constant than
those already described. When the urinary organs are present, they terminate in the ree-
tum : they have been found in certain carnivorous coleoptera. The fluid which has been
called the urine in insects, is caustic and odorous : it is often discharged by the carabici,
on handling them, in jets, which, when falling upon the skin, occasion a transitory burning.
In connection with this secretion, may be noticed that peculiar to the bombardiers, which
is discharged in explosive jets, and is supposed to be intended as a means of defence. The
name of the genus possessing the power of producing explosive jets of fluid, is Brachinus.
I am not aware of the fact, if it has been ascertained, that this fluid is similar in composi-
tion to that of the higher animals, or that it contains urea.

In concluding our remarks on digestion in insects, we may observe that the function is
performed in ways quite as numerous as in the higher orders of animals, though there is
no departure from the general principles which prevail in the vertebrate and molluscous
types. There is always an apparatus for trituration, or mechanical separation of the food
into fine parts : it is thereby prepared for the action of the several fluids which concur in
the digestive process, and which exercise some peculiar chemical influence that serves to
separate the nutrient matter from the useless portion of the food. These fluids are more
or less acrid in their nature : thus the saliva injected into the wound made by a flea or a
fly, for example, by the ¢abanus, occasions inflammation and itching ; and this irritation
is designed to favor the insect, inasmuch as it produces a flow of blood to the wounded
part. An effect of saliva is seen upon leaves attacked by the caterpillar, which very soon
suffer a loss of color; and as the morsel swallowed passes along from one receptacle to
another, it is constantly undergoing changes : it is softened in the crop ; in the gizzard,
it becomes pulpy ; and in the true stomach the chyle is formed, and is at once recognized
by the globules it contains.

A controversy has been long maintained respecting the office of those tubes which have
been called hepatic or biliary. Some eminent physiologists have regarded them as urinary,
inasmuch as uric acid is sometimes found in them; but as this is not always the case, a
compromise seems to have been made by regarding them as both biliary and urinary, and
giving them a corresponding denomination wrino-biliary. The circumstance that the same
tubes which have since been found sometimes to contain urine were regarded as biliary

{ Acricutturat Report — Vor. v.] 3

tubes by the older and physiologists, is accordant with known facts in the
economy of the lower among which it is common for an organ to perform a double
function. * ele

The food in t canal of insects is moved along by a peristaltic motion : the
canal, the lied with a muscular apparatus. Indeed, from the phenomena
exhibited, we that the apparatus has a construction and parts such as have

place in quadru : thus the coats of the alimentary canal are three, a mucous, a cellu-
lar, and a muscular coat; the first being the internal one, the muscular the outside, and
the cellular in the middle. The mucous coat is thin, often transparent, and difficult to
detect. The muscular coat is perfectly developed : its fibres are both longitudinal and
circular ; and where the constrictions peculiar to the tube exist, there it is more perfectly
developed, or in greater force. These muscles serve partly as sphincters, and also to keep
up a continual movement.

Crmcunation. Insects are furnished with a circulatory apparatus ; it consists of a dorsal
vessel, which, as its name indicates, is a tube running beneath the dorsal face of the ex-
ternal covering. This is the central organ, and is equivalent to the heart in the higher
orders of animals; and the circulation is continued from the dorsal vessel, in channels —
excavated in the tissues, The structure of the dorsal vessel permits the blood to flow from
the posterior to the anterior part of the animal, by means of a series of valves opening
forwards. The blood is transmitted to the thorax and head, the wings and legs, and returns
through certain channels denominated veins, which open into the dorsal at different points
through the valves; but the larger portion of the returned fluid collects in the posterior
chamber, and passes the whole length of the vessel. The vessel has been, and still is, re-
~ garded by some physiologists as analogous to the heart : others, however, consider it as
more analogous to the aorta of quadrupeds.

It does not seem to be a matter of much importance whether we regard the so-called
dorsal vessel a heart, an aorta, or an organ compounded of both, the posterior segment
taking more especially the form and function of an aortic vessel. Its visible contractions,
as seen through the transparent covering of many insects, furnish ostensibly valid reasons
for regarding it a heart.

The fluids which cireulate in the vascular system of insects are usually white, carrying
along distinct corpuscules having forms like those which are found in the higher and more
perfect animals.

In connection with the foregoing facts, it should also be stated that the circulation in
insects is carried on in vessels having close proximity with those of another kind, namely,
the air-vessels, or trachea. The two classes are easily distinguished from each other by the
structure of the latter ; for in order that air may traverse the insect system, it is necessary

CIRCULATORY AND NERVOUS SYSTEMS. 19

that its conducting vessels be maintained in a tubular form : this is effeeted by means of
a spiral elastic thread wound closely upon itself. By this means the vessels are prevented
from collapsing, the air enters freely at the sides of the insect, and permeates perfectly the
whole system. The air, then, is constantly in contact with the thin membrane intervening
between the trachea and those vessels which transmit the blood to the different parts of
the insect’s body and extremities. Recent observations prove, in regard to the relations of
blood and air, that the former moves through the space between the outer and inner
membranes, in which a spiral filament winds, so as to bathe the exterior of the air-tubes
themselves*.

It would therefore seem that there is in insects a most complex system of spiral vessels
or air-tubes, in connection and close relation with the,vascular system, both being dis-
tributed with the greatest minuteness throughout the whole body. There is still another
provision for keeping up a supply of air especially in those inseets whose flight is rapid,
and requires to be Jong sustained : it is found in the air-sacs that are distributed in dif-
ferent parts of the body; they serve not only to retain a due supply of air, but also to
buoy up the body and render it lighter. The pulmonary system, by a combination of elastic
tubes and sacs, receives an extraordinary development, so as to compensate in the most
perfect manner for the deficiencies resulting from a less perfect form of circulation ; for
powerful museular motion requires a rich supply of oxygen, rather than food, in order to
give energy and activity to the muscular system.

From these facts, it appears that insects occupy no mean place in the scale of being,
when they are ranked according to the development of their cireulatory apparatus and
the accompanying tracheal system. This combination, so far as the power of muscular
motion is concerned in the estimate, serves to elevate the fhsect to a rank but little below
that of the vertebrate class.

Nervous system. The nervous system consists of a pair of chords extending through
the insect, upon the interior abdominal face,and connected at each segment by a ganglion.
Thus disposed along the ventral face of the body, the nervous system forms a symmetrical
whole. The ganglionic masses of the head, however, are more largely developed than those
of the trunk : this is necessary, from the condition of the eyes and the perfection of the
masticating apparatus. The cephalic centres are placed also above the esophagus. So the
nervous centres which supply the wings and legs are larger than those of the abdomen.
We see here again a provision for the locomotive apparatus, by which a due supply of
nervous power or force is secured.

There are probably but few instances in the animal kingdom, that exhibit such minute

* See Canrentér, p. 382 of his General and Comparative Physiology.

20 NERVOUS SYSTEM; SENSE OF TOUCH.

subdivisions of matter as certain portions of the nervous system do. Thus when it is stated
for the first time in our hearing, that the eye of the common house-fly is compounded of
no less than 4000 single eyes, it seems impossible that a nerve, originally microscopic, can
be subdivided into threads or fibres sufficiently fine to furnish a nerve to each simple eye;
and when we are further informed that the eye of the dragon-fly has (24,000) six times
as many subdivisions as that of the house-fly, our faith is still more severely taxed ; but
to suppose that a filament is wanting in an eye, is to suppose that the eye is made in vain;
for the eye depends upon its nervous filament, however slender that may be, for its power
of vision.

The sympathetic system of nerves in insects has been known from the days of Swam-
s“enpam, who first discovered it in the rhinoceros beetle. While this system is found more
or less perfect in all articulated animals, it is specially perfected in insects. The imperfee-
tion.of the nervous apparatus consists in the absence of the cerebral masses, or of all that
portion concerned in the formation of ideas. Nothing appears in the nervous system of
the articulata, higher or above the ganglionic centres which connect together the double
ventral chord. The ganglia of this system which are more particularly devoted to the
purely animal functions, undergo a slight change during the passage from the larval state
to that of the perfect insect ; the change consisting chiefly in a concentration of nervous
matter upon those ganglia which are subservient to the function of locomotion. The sym-
pathetic system, however, undergoes no change : it is equally perfect in the larva as in
the mature animal, and reaches its full development in this early stage of existence, there-
by showing that it presides over the functions of vegetative life.

It is scarcely necessary to speak more particularly of the functions of the nervous
system. It may, however, be observed, that it is upon this system that sensation depends,
and the nervous fibrils are the channels through which the properties of external bodies
become known to the individual. If we may judge of causes by effects, we are warranted
in believing that impressions are received by insects from without, in the same manner as

is the case with the higher animals; and that they possess all those special senses which
belong to the latter, and some of them in much greater perfection.

Towen. The sense of touch in insects, in consequence of the hard covering of their
bodies, must be confined to certain parts. Those who have watched their motions are fully
convinced that the palpi are the organs in which this sense is concentrated, or in which it
exists in its greatest perfection. These organs are constantly applied by the insect, after
the manner of feelers, to the external bodies with which it comes in proximity ; and they
are well adapted by their structure to fulfil such a purpose, being flexible, and furnished
with a soft and delicate integument.

FUNCTIONS OF HEARING, TASTING, SMELLING, AND SEEING. 21

Hearinc. The phenomena which indicate the existence of the sense of hearing are
perhaps more equivocal than those of touch. Still attentive observers have noticed that
insects seem to place themselves in an attitude of listening, when loud sounds are emitted
from any quarter in their vicinity : they erect their antenne, and remain motionless for
the time being ; and when the disturbance has ceased to excite them, they resume their
ordinary movements. From the position of the antenne, then, under the circumstances
alluded to, it is inferred that they are connected directly with the function of hearing.
Beneath them is a nerve connected with a soft membrane, which seems to be adapted to
this special end. The antenne in themselves extending outwardly, must become sensible
of the vibrations in the air, and transmit them to this delicate auditory apparatus lying
immediately beneath. The organs are often long-branched, or plumose, so as to increase
the extent of surface. This view of the office of the antenne does not conflict with the one
often entertained, namely, that they may also be useful and employed as organs of touch.

Taste. The existence of this sense rests more upon analogy, than upon well determined
facts to support and prove its existence.

Smexv. Insects are attracted to odorous bodies from a distance : hence there can be no
doubt that they are possessed of the sense of smell in great perfection, although its precise
location is a matter of great uncertainty. Several different parts of the insect’s body ha¥e
been conjecturally assumed as the seat of this sense ; and it has often been assigned to
parts that are variable, evanescent, or of occasional existence only. If analogical reasoning
were to be our guide in this ease, we should point to certain inward parts of the body that
are in direct relation with the external air. In the mammalia, though the organ of smell
is located in the head, yet its distinguishing characteristic is its immediate communication
with the atmosphere, and the sense itself is exercised only when the air is inhaled. It is
not necessary to infer, that because in the higher animal it holds this intimate relation to
the head, that it must oceupy the same place in the insect : it is more consistent to suppose
that its closest relation is with the respiratory organs. It is highly probable, therefore, that
the trachea and spiral vessels, which conduct the air inwards, constitute the channels by
which this sense is furnished with the odorous particles on which the sensuous nerve is to
operate. Accordingly this view is looked upon with favor by Cuvrer and many other dis-
tinguished physiologists.

Sicur. Of all the senses, that of sight seems to be the most perfect in insects. The
organ is compound, or, in other words, consists of many eyes comparted together, each of
which is perfect in itself, being furnished with the proper humors and lenses essential to
the exercise of vision. In addition to the compound eye, which often occupies the largest
portion of the head, they are often furnished with simple eyes upon the forehead : these

, 2 FUNCTION OF VISION.

have received the names of ocelli and stemmata, and are generally three in number, and
arranged in the form of a triangle ; but there may be but two, or only one, Their structure
qualifies them for viewing such objects only as are close at hand.

The compound eye presents a reticulated appearance under the microscope : the surface
is convex or globular; but the organ is immovable, except by the motion of the head.
The reticulated appearance is produced by the lines that mark the boundary of each eye
or lens : these are hexagonal, and their number is almost incredibly great in some species.
They vary in this respect from 50 in the ant, to 25,000 in a species of Mordella : the
butterfly has 17,000, and the dragonfly 12,544. Each eye is furnished with an apparatus
sufficiently perfect for the exercise of vision in its sphere ; it has its lens for refraction,
its choroid for the correction of aberration, and its retina for the reception of the images
of external objects. Each single eye, however, must embrace an extremely limited field of
vision, and there is no doubt that it requires the use of many of these eyes to see a single
object ; for only those rays of light that fall perpendicularly upon the eye can reach the
optic nerve.

The eyes of predaceous insects, such as the dragonfly, are large, prominent and globular :
hence they enjoy, altogether, a large field of vision. In those insects, on the other hand,
which are confined in their range, or are parasitic, the field of view is diminished by a
reverse of circumstances.

The nerve of each eye terminates in a common nerve : this must be regarded as the
sensorium commune, the nervous plane upon which the image of an object is spread. Some-
times the eye is pedunculated, or placed upon a footstalk : sometimes it is semicireular,
in consequence of the implantation of the antennw, and indeed this implantation may be
such as to give the semblance of four eyes. In other instances the size of the eye is a sexual
mark. P

We are too much in the habit of looking vaguely upon the insect tribes. While we
recognize the movements of the vertebrated class as resulting from distinet acts of the will,
” and as controlled by internal feelings, we are little disposed to entertain the view that the
apparatus of a fly or a beetle indicates similar internal motives for action ; or, in other
words, we do not possess so lively a sense of the perfection of the being of the insect, as
of the being of the higher order. We see, however, that insects have eyes to see, ears to
hear, and organs of smell ; a highly developed nervous apparatus, and an active cireula-
tion : in fine, the insect moves in a world of its own, which takes no part in the sphere
belonging to the mollusea or vertebrata. Its senses and organs of animal life, however, give
it a wide sphere of activity, and have prepared it for fulfilling important functions, and
furnished it with a capability to affect very materially the interests of man. Being widely
diffused, and their life overflowing with activity, always moving as if impelled forward by
important business or engaged in errands of the most momentous character, they seem to

FUNCTION OF MOTION. 23

make the most of their brief and uncertain existence. Witness the energy of the dung-
beetle in finishing the ball in which it has deposited its egg : it often dies in the act of
providing for the continuance of the life of its kind. To some these actions may seem less
interesting, because instinctive ; but surely the faculty of instinct affords matter for deep
thought to the ordinary observer, and to the philosopher it must possess an interest next to
that of reason itself. Instinct urges the individual forward to the fulfilment of its destiny,
but it makes no inquiry as to the cost.

Muscunar motion. The insect enjoys a full development of the power of motion,
especially.in its perfect state : the two kinds of muscle, striated and non-striated, are al-
ways present. Every part of the system is supplied with muscular fibres ; not only are the
legs and wings largely supplied with them, but also the abdomen and various parts of the
trunk, head, and thorax. The most interesting fact which appears in this connexion, is the
power of the insect to sustain a long and vigorous flight : thus the dragonfly darts for-
wards, backwards, or sideways, and is able to outstrip the swallow in its most rapid course ;
and this it can do for hours together. Taking into consideration the diminutive size of
insects, we readily see, that in proportionate locomotive power, they far excel the verte-
brate animal. We have already observed that their joints usually admit of but two kinds
of motion, forwards and backwards, or the ginglimus movement : when, however, this
motion is exerted in extension and flexion, as in the leaping of the grasshopper or flea, we
cannot fail to perceive that their powers in this respect, also as in flying, are far superior
to those possessed by any other class of animals.

Though the larval state of insects is generally sluggish, we are not without many
examples where there is a great degree of activity. Wesoften see the caterpillar hurrying
along as if it were in great haste, though the space it is able to traverse is quite limited.
We observe, in all these movements, an aim to preserve life : the life of self, however, is
subordinate to that of kind or progeny.

Propacation. Insects propagate their kinds from eggs laid by the female, subsequent
to the act of congress with the male : the sexes are therefore distinct. Their power of
multiplication is immense, especially in those insects which produce several broods in a
season. But there is a remarkable exception to the foregoing rule : the aphis increases by
a process of gemmation ; females being cast off at once for several generations, of which
each possesses the power of multiplying its kind in the same way. Carpenter likens it to
the gemmation of the polypi, “the individuals being budded off from internal stolons,
instead of being developed from ova provided by the female and fertilized by the male.”
It has long been known, that in the aphis, this method of propagation is repeated to the
seventh or ninth generation. At the end of the season, the perfect individuals, both male

24 FUNCTION OF PROPAGATION.

and female in a winged state, are produced, by the congress of which ova are fertilized :
these are preserved through the winter.

It would seem from this, that although in the articulated class budding is resorted to to
multiply the number of individuals, yet it is not adequate to continue the existence of the
species. Calculations have been made of the numbers which an aphis may produce in a
single season, provided the individuals are not destroyed by accident. According then to
calculation, based upon observed facts, the whole brood in a season from a single aphis
will amount to the inconceivable number of 1,000,000,000,000,000,000! From such an
ability to increase, we should at first thought be disposed to expect a result approaching
the calculated numbers ; but it is gratifying to observe, that where the powers ef increase
are extended and multiplied as in the ease of the aphis, the destructive powers are equally
multiplied and active : there is therefore but little reason to fear an excessively injurious
multiplication in the midst of so many enemies. The aphis is extremely feeble : the touch
destroys it; the winds, rains, and cold sweep off its numbers by hundreds of thousands.
The excessive multiplication of individuals is only a means of supplying an increased
number of consumers : hence instead of an approach to the enormous number indicated
by calculation, their actual numbers will fall infinitely short of it. The balance of nature
is always preserved ; and wherever danger seems to point, there checks are provided, which
pat an effectual restraint upon inordinate increase. We may conceive of what is possible;
but the actual jyst suffices to keep up a suitable equilibrium : at most the threatening is
transient, and recurs only at wide intervals.

CHAPTER III.

REMARKS ON THE CLASSIFICATION OF INSECTS.

Tue multiplication of species renders it necessary to resort to some kind of arrangement,
by which they may be gathered into groups under one or more common characteristics.
It matters not which of the kingdoms of nature we enter, if the individuals are dispersed
singly or unarranged into families or groups, no one can hope to possess himself of an idea
of their relations. Memory would be too much burthened in the attempt to comprehend
the relations, or retain the characteristics of the species which belong to a single district
of the globe. Hence the necessity for devising some scheme by which we may group to-
gether those which are alike, and to which we may apply a positive expression indicative
of that likeness.

There is perhaps nothing easier than to say on what general principle such a scheme
should be based ; for it is plain enough that resemblance must be the basis of all schemes,
and indeed ever has been since attempts at classification have been made. Classification is
founded on resemblance ; and yet there are so many points of resemblance, that it becomes
necessary to make a choice. It is evident that the resemblances in the mineral kingdom
are not those of the vegetable or animal, and those of the vegetable kingdom are yet in-
applicable to the animal. This, however, is not the difficulty : taking each kingdom by
itself, and selecting from among its individual members certain characters which belong
to the many, they fail us in attempting to make a general application of them ; they either
cease to exist, or else possess an importance so variable or inconsiderable that they become
uncertain as marks suitable to be employed in classification.

There are two kinds of resemblances in the natural world : there are morphological
and teleological resemblances. In the first we seek for external forms ; in the second, we
look for ends. The wings of a bird, of a bat, and of an insect, possess a teleological re-
semblance, but not a morphological one : the end, or final cause, is the same; but the
form, arising from structure, is quite different. It can be scarcely possible that final causes
or teleological resemblances should be available in classification, although they may be
useful in many other respects ; and we may remark here that it is only by an attentive
study of morphology that a true basis for classification can be found, and all the schemes
that have been successfully applied belong to this kind. Availing ourselves of the principles

- ~

found in forms, we may proceed with a degree of certainty ; and when forms are correctly
defined, we may escape most of the graver errors in the formation of groups.

I do hot propose to enter into the details of the principles of classification in this place,
but shall proceed at once to the modes which have been proposed and followed by the

principal English entomologists.
The first classification is that of Srermens, in which the first grand division of the insect

kingdom is into two subclasses :
FIRST SUBCLASS «: MANDIBULATA. SECOND SUBCLASS ; HAUSTELLATA.
Order 1.. Srnerstrrena. Order 1. Hestrrena.
2. Oxrworrena. 2. Homoprenra.
3. Neonorrera. 3. Lerrporrera.
4. Deamarrera. 4. Drprera.
5. Tatonorrera. ‘ 5. Homacorrera.
6. Hymenorresa. ° 6. AruAaNIPTERA
7. Arrera.
ay Insects are classed by Westwoop in the following manner :
FIRST SUBCLASS : DACNOSTOMATA. SECOND SUBCLASS : ANTHOSTOMATA.
(Mouth with jaws) ( Mouth with « socker)
Order 1. Hywenorrera. Order 1. Drprena.
? Osoulant Order Srxersirrera. Osculant Order Homatoprera.
Order 2. Coteorrera.
Osculant Order Evrtexortera. Osculant Order Armantprera.
Order 8. Ontnorrena. Order 2. Herenorrena (including the water-
? Srnerstrrera? bugs).
Order 4. Nevnorrera. Order 3. Homoptera.
?
Order 5. Tricnorrera ( Phryganca alone). Order 4. Lepivorrera.

CHAPTER IV.

ORDER I. COLEOPTERA.

Tue Coteoprrera is the order which has usually been first described, and Westwoop has
followed the common practice in this respect in his Genera of British Insects. This order
is thus characterized :

Anterior wings horny or leathery, concealing the posterior when at rest, placed parallel and
joined by a straight suture. Posterior or inferior wings membranous, longitudinally and transverse-
ly folded. Mouth furnished with transverse jaws. Pupa incomplete.

The insects of this order are denominated beetles : they constitute the most beautiful of
the class, and occupy the foremost rank among the tribes. They are grouped as follows by
Mr. M‘Leay :

1. GEODEPHAGA : containing those beetles which haye setaceous antenne, with the
outer processes of the maxille palpiform.
2. HYDRADEPHAGA.

In the first division the following families are included, being the old genus Caragus
subdivided into
CIcINDELID2.
CARABIDE.
GEODEPHAGA : HarpaLipz,
Scaritipz.
BracHINIDE.

HYDRADEPHAGA : Gru
YTICIDE.

The above is regarded as a normal group, and is followed by an aberrant one, character-
ized by clavate antenne, or such as become gradually thickened towards the apex, and the
external lobe of the maxilla losing its palpiform character. This constitutes the Rypopnaca
of SrePHEns. -

Heresocentpa?
Parnipx.
PHILHYDRIDA : Herornontpx.
Hypsrormiupsz.
Srumamwupat?

Scarmipupa.
Sirmip2x.
NECROPHAGA : Nimipvuipa.
Exoipa.
Deannstips.

Srarnycinipx.
Srenipx.
BRACHELYTRA : Omauip 2.
Psevarnips.
Tacnyporip2.

Wesrwoon, however, in his work on the British genera, adopts, in preference to the
foregoing, the tarsal system, and hence recognizes the following subdivision :

1. Penramena : tarsi with five joints ;

2. Hereromena : tho four anterior tarsi 5-jointed, and the two posterior 4-jointed ;
8. Psevporereamena : tarsi 5-jointed, the fourth exceedingly minute ;

4. Psecporrimera : tarsi 4-jointed, the third joint very diminutive and concealed.

Cicindelide.

Ti family of beetles, which are known under this name, are among the most beautiful of
the insect tribes : their colors are brilliant, and their markings-add to the beauty and
elegance of the colors by contrast. In size they oceupy a middle ground : the largest
searcely exceed an inch in length, and the smallest are at least one-third of an inch long.
Their habits are as interesting as their colors are beautiful ; their watchfulness is untiring ;
and though their flight is short, it is difficult to capture them. In the nature of their in-
stincts they agree with the carnivora among the vertebrate class of animals : they are
flesh-eaters ; but in order that they may capture and secure the living insect as their prey,
they are qualified to give chase either on the wing or on foot, and they make war upon all
insects that are not too strong for them. The cicindelid# hunt upon sandy and arid plains,
and seem to delight in the heating rays of the sun; for in hot days they appear far more
numerous, flying and alighting upon the ground before us in dry paths, and turning their
heads watchfully towards us when they rest for a moment.

FAMILY CICINDELIDA. 33

As the cicindel subsist solely upon other insects, or, in other words, are carnivorous,
they cannot be regarded as injurious to the farmer : they are rather beneficial than de-
trimental to his interests. Their markings, together with their predacious habits, have
given them the name of tiger beetles. It is evident, from the prominence and size of their
eyes, that they are well provided with one essential power to enable them to pursue suc-
cessfully the means of subsistence, namely, keenness of vision. So too their jaws or man-
dibles are powerful : their legs, however, are long and slender, and are adapted rather for
quick movements than for the performance of feats of strength.

The larve of the cicindele are no less predacious than the perfect animal. They are
represented by Wesrwoop and others as having a large head armed with powerful jaws,
and capable of burrowing in the earth to the depth of a foot. At the mouth of this burrow
they lie in wait for their prey, which they seize and drag to the bottom to devour at their
leisure. To aid in ascending and descending these burrows, they are provided with two
hooks on the back : some observers, however, suppose these hooks may assist in holding
their prey, when bent in a suitable manner ; for, on entering the mouth of the burrow with
their prey) they suddenly slide to the bottom.

These insects, then, in all their stages, are predacious ; and inasmuch as their numbers

are less than those of many allied families, and their instinets are such as require a higher
development of locomotive apparatus, they may well be regarded as occupying the highest
rank in the articulated class.
* ‘The Crctypetrom are in general easily distinguished : their colors are usually green or
gray combined with a brassy or bronzed tint, with whitish spots for ornament in combina-
tion with brindle spots or angulated lines, which give them all a pleasing and indeed an
elegant appearance. From their powers of flight, the cicindele have sometimes received
the name of Eupterinea.

The family Crcinpetip” has been divided by Mr. Harxts into the following groups :

1. Labrum with three teeth ; thorax contracted behind.
2. Labrum 1-toothed ; thorax quadrangular, flattened above and dilated behind.
3. Labrum one toothed ; thorax nearly cylindrical.

1. Labrum provided with three teeth; thorax contracted behind.
CICINDELA.

The genus Cicrnpexa, as defined by Westwoon, is described as follows : The males have
their anterior tarsi elongated and dilated. The elytra are oblong-ovate and depressed.
Thorax subquadrate. Internal maxillary palpi with joints nearly equal in length ; the two
basal joints of the labial palpi short, the third is elongate and ciliate, and the fourth
clavate and naked. Antenne are inserted into the anterior margin of the eyes. The head

Kinsy remarks, that though this species is common in this country, it is not noticed by
Say, who perhaps mistook it for C. sylvatica (Lixy.), “of which it may be regarded as the
American representative, and with which it agrees in its prominent upper lip and the
shallow impressions and markings of its elytra, as well as in its general color; but it is
smaller, has a white instead of a black upper lip, with an obtuse longitudinal ridge and
not an acute one, terminating in three almost obtuse short teeth instead of a longer one,
and likewise by the want of the silky lustre produced by granulations much more visible.”

Carabide. ‘

Tue insects embraced in this natural family, or group, possess several characters in com-
mon, by which they are distinguished from the cicindelidw, and from those which are to
follow. The distinguishing characters, as given by systematic writers, are as follows :

‘ Anterior tibia without emargination on the inner side. Head narrower than the thorax ;
‘eyes rather prominent; palpi with the terminal joints often compressed, large, and
‘ somewhat triangular in shape ; mandibles simple, moderately long and rather thick.’

This family is divided by Westwoop into five sub-families, each embracing several allied
genera. With the intention of giving these sub-families a natural arrangement, Westwoop
places first upon the list the Brachinides, which stand near the head of the Gropernaca ;
and ends with the Bembidiides, the sub-aquatics, or the sub-family which links the Gro-
prernaca with the Hyproprrnaca. The order, then, in which the several sub-families stand
to each other, is as follows :

FAMILY CARABIDA. 89

1. Anterior tibia notched on the inside.
1. Bracuinipes : Bombardiers. Elytra truncated behind. Tarsi of the males seldom dilated at
the base.
2. Scariripes : Burrowers. Elytra rounded at the extremity. Abdomen pedunculated.
3. Harvauives : Blackclocks. Elytra rounded behind. Abdomen sessile.

11. Anterior tibia without a notch near the tip.

4. Canasiwes : Dischargers.

5. Bempipupes : Subaquatics. This sub-family is distinguished from the four preceding by its
palpi being terminated by a2 minute conical joint, while the same organ in the former is
terminated by a joint equally large with the others.

The habits of these sub-families differ from each other in many respects. The most
important fact, however, which should be stated respecting the numerous species belonging
to this family, is that they are friendly to the farmer. Many of them live upon refuse mat-
ter : some devour those insects that are injurious to the farmer : hence they should not
be destroyed ; and not only so, but it seems even possible to employ some species of them
for the very purpose of extirpafing injurious insects. To exhibit the mode in which this
may be accomplished, I copy the following communication from Prof. Harpeman, which
he had translated from the fifth volume of the Revue Zoologique. The facts and remarks
are quite important, and should be generally known, and therefore no apology is required
for introducing them in this place.

«“ There is,” says M. Borscrravn, “a numerous family, composed of carnivorous species,
most of them robust and very voracious, which may be multiplied with impunity, and
without fear, in our gardens. They do not, indeed, feed upon plants, which they are called
to protect : on the contrary, they and their larve make great havoe of the herbivorous
insects, and at the same time of the limaces and helices,” or land-snails, with and without
shells; which, in Europe, are destructive to vegetation, but cannot be considered in the
light of noxious animals in America. Nevertheless we are occasionally put in possession of
the means to destroy them, taken from English horticultural works ; just as we are told
how to protect ourselves from insects which are not found upon our side of the Atlantic.
This is principally owing to the fact that the same vulgar name is applied to distinct objects
in Europe and America.

‘ The insects alluded to are the carabide. “ Well, who would believe it,” continues the
author, “the greater part of the cultivators crush these powerful auxiliaries with a kind
of avidity; whilst the butterfly, which is to give birth to numerous caterpillars, which
afterwards devour their plants, is the object of their admiration, and frequently even of
their protection. A multitude of noxious insects, after having for several years committed
ravages upon our property, disappeared suddenly, without our being made acquainted with

pat any In looking more closely into these matters, one might be assured, that in most
an enemy of the insect which has disappeared, ee Eo ee

‘ “ The thick foliage of a fine avenue of poplars was all at suse iaiiek levee immense
quantity of the caterpillars of Bombyx dispar. I thought of giving them the Calosoma
sycophanta for company ; as, like them, {ft passes its life upon the trees, feeding upon the
caterpillars which it meets, and even deposits its eggs in their nest, that its voracious
progeny may procure nourishment more easily and in greater abundance. Well! this insect
multiplied itself with a rapidity truly astonishing ; and the caterpillars disappeared, with-
out those who were witnesses to the destruction having the least idea of the causes which
produced it.” The author then gives it as his opinion that the neighborhood of the city of
Toulouse is so little ravaged by the Melolontha vulgaris, which is so destructive in other
parts of France, because the Carabus auratus is very common in the fields, meadows and
gardens. It is known, he remarks, that the Carabus auratus seizes and devours the Melo-
lontha previous to the deposition of its eggs ; and that it is more fond of these, than of any
part of the insect.

‘« One would be much deceived,” he continues, “in believing that it is always easy to
make an advantageous use of this means of destruction, a profound study of the manners of
insects being often indispensable to arrive at the end proposed.” Here is an example : “The
most robust of our carabi, the Procrustes coriaceus (Lixyxus), had served me admirably in
the centre of France to destroy the little insects which attack the plants in gardens : here
(in the south) this insect does not destroy the same species; and although very common, it
is unknown, or hardly every met with. The reason is, that in the centre, the west, and
probably the north of France, this procrustes is diurnal, requiring only cool and shady
places : with us (in the south, under a warmer climate) it is, on the contrary, essentially
nocturnal, and therefore destroys only such insects as are, like itself, nocturnal, or which
remain within its reach during the obscurity of night.”

‘“In transporting into my garden twenty of the Carabus auratus, I had thought to
destroy the collections of Forficula (no destructive species found in America) which had
chosen it for the theatre of their ravages.” To his great astonishment, the cerabi, which
will actually destroy the forficula, were either found starved to death, or left the place ;
and the latter continned their devastations! The reason given is, that the forficule are
essentially noeturnal, and, during the day, keep themselves hidden in crevices into which
the carabi cannot follow them : these latter, too, are only active during the middle of the
day, and in the heat of the sun. But the resources of our persevering entomologist were
not yet exhausted ; his next expedient being to introduce a smaller carnivorous insect
common in France, the Stephylinus olens, which, he remarks, “filled all the necessary
conditions for the destruction of the forficule.” ‘

« «You see, then, gentlemen,” says M. Borscinavn, in conclusion, “ that it is indispen-
sable to study the manners and habits of destructive insects, that their instinct and address
may be successfully employed for the destruction of the species able to do us injury. Then
in place of barbarously crushing the useful species which have the misfortune to be not
always ornamented with the rich colors of the butterfly or the buprestis, we will endeavor
to protect them and propagate their race. We will find auxiliaries in them the more
valuable, as they increase with our adversaries, and as they alone are able to rival the
cunning of these ingenious enemies.” ’

Brachinides.

Tue sub-family Bracuintpes may be known by the shortness of the wing-covers, which
are not sufficiently prolonged to cover the extremity of the abdomen. In addition to this
character, the head and thorax are narrower than the abdomen. The labium is often oval
or square, and is occasionally furnished with two smal] lateral linear lobes. The penulti-
mate joint of the tarsi is bilobed in many of the small species : the anterior tarsi of the
males are, very rarely, dilated at the base. Some species are destitute of wings (Wesr-
woop).

The most curious fact connected with the natural history of this sub-family is the
means by which they defend themselves against the attack of an enemy. When pursued,
they suddenly discharge from behind a highly volatile and elastic fluid, possessing con-
siderable pungency : this sudden discharge, which is accompanied with an explosion,
both irritates and confuses the pursuer, so that the intended victim has opportunity to
escape. From this singular mode of defence, these insects have received the name of
bombardiers. The fluid discharged is caustic, and stains the skin yellowish brown. They
live under stones, logs or boards in fields. Several individuals are often found in the
spring together, as if their habits were of a social nature.

Scaritides,

Tue most remarkable peculiarity in this sub-family is the wide space between the thorax
and abdomen, by which the latter appears pedunculated : the posterior angles of the
former are also so rounded, that its form is lunate. The antenne are short, moniliform,
and the first joint is the longest; the head is large; the tibi# of the anterior legs are
broad and dentated, having the appearance of being palmated. The mandibles are large
and powerful, and armed with broad teeth ; labrum short, entire or dentate, sometimes
trilobate ; mentum tridentate, with the middle tooth strong ; labial palpi two- and four-
jointed.

The scaritides are carnivorous, and in this respect bear a close resemblance to the allied
subfamilies : some living in the ground, upon other insects or their larve ; and some
frequenting the seacoast, burrowing in the sand, and living upon the dead careases of
shrimps. In this State, they burrow in the ground, or live under stones. A-Jarge-species

nocturnal feeder, and is found quite abundantly in Central New-York. Its singular form
renders it easy to be distinguished.

tenths of a line.

Harpalides,

Tue elytra of this sub-family cover the abdomen; the extremity is rounded : they are
also sessile, and not pedunculated. The anterior tibie are deeply notched near their tips,
and, in the males, the basal joints are dilated. The mentum is emarginate, though it is
occasionally entire : the centre of the emargination has generally a spine. The antenne
are filiform ; labrum quadrate, rarely bilobate, but sometimes emarginate in front; man-
dibles generally with one or more denticulations ; mentum deeply emarginate anteriorly,
the emargination simple or sometimes toothed ; body elongate.

These insects are not so voracious as those of the succeeding family, the Cananirs.
The predominant colors are black, while a few of them are adorned with brillient metal-
lic hnes. Some are apterous, and run remarkably well. The larva, like the perfect inseet,
lives beneath stones, and feeds upon other insects or their larva. They are cylindric and
elongate, but slightly flattened or depressed ; and they have twelve rings, which are more
or less sealy : the Jast ring is armed with two small processes.

The sub-family contains many genera, which, though related to each other, are not
readily separable into groups. Sternens divides them into three groups, viz :

50 ORDER COLEOPTERA.

Carabides —

Coxstirere the fourth sub-family of the Canampa:. They are distinguished from the other
subfamilies by the absence of the notch, which, in the allied species, is situated near the
extremity of the anterior tibia : the only approach made to it, is by the presenee of a
slight groove in the place of the notch at the extremity of the tibia. The elytra are entire,
and cover the extremity of the abdomen : antennm setaceous ; labrum may be simple,
bilobate or trilobate; mandibles simple or merely one-toothed, rarely tridentate ; maxille
ciliated internally, and furnished with a claw at the tip; labial palpi four-jointed ; men-
tum large, broad, and generally produced in the centre ; anterior tarsi greatly dilated in
the males.

This subfamily contains many large showy insects : they are mostly apterous, and their
elytra are often elegantly marked with metallic spots, or set off with splendid metallic
hues.

The carabides run fast, and are very carnivorous in their habits ; hence they should be
preserved, as they are friendly to the farmer. Some of them discharge a powerful odor
when taken, which is exhaled from a fluid ejected from the abdomen, and remains a long
time.

The Genus Canranvs, the typical one of the family, contains, according to Mr. West-
woop, notwithstanding the restrictions to which it has been subjected, nearly 200 species.
By fur the greater number of these species are confined to northern climes.

oA ORDER COLEOPTERA.

HYDRADEPHAGA.

Tux insects included in this section reside in water, and hence their legs are transformed
into organs suitable for moving in this element. In addition to the transformation of the
legs into swimming organs, the body undergoes a change of form, becoming oval or boat-
shaped : in fine they are thoroughly fitted for the element in which they are to move,
being endowed with the means of pursuing their prey, and furnished with all the con-
veniences which their congeners upon the land possess. Although they subsist in water,
yet they are not provided in their perfect state for obtaining a supply of air from the
element in which they move : they are air-consumers, and are obliged to rise occasionally
to the surface to obtain a supply of air for respiration.

The Hypaapernaca are predacious beetles; and although it is not important to the
farmer to know them in an economical point of view, still some of the larger kinds prey
upon the ova of fish, and even upon their young; and in this respect, they are not entirely
destitute of interest to the owners of fish-ponds. Regarded as animals which live by the
chase, they are truly more greedy and gluttonous than the predacious land beetles ; they
are pre-eminently voracious and destructive. Their larvae, of course, are aquatic ; and
they too feed voraciously upon other aquatic insects. The perfect animal, though fitted for
the water, is not confined to it : it may take wing at evening, and enter dwellings, like
moths, being allured by the dazzling light of lamps near a window. They obtain air by
resting upon the surface, and raising their elytra ; this brings the air more immediately
into contact with the spiracles of the insect.

Srernens divides the Hyonaperuaca into two families, viz :

long, setaceous : embracing the Dytictp2 ;

ANTENN®
. short, clavate : embracing the Gyainips.

1. The Dyricro are furnished with rather long setaceous antennae ; their bodies are
oval, being rounded anteriorly and posteriorly ; their thorax is short and transverse, and
their legs are formed for swimming : the posterior ones, however, are especially adapted
to this end, by their great length, and by being furnished with two rows of dense cilia
arranged along the edges, with the view of increasing the width of the oar; the tarsi are
also flat in the fhales, and the anterior ones are more dilated than in the females, The
mandibles of the larva are much bent, and are pierced for the purpose of extracting the
juices from the animals upon which they subsist. Their respiratory organs are situated
behind, and consist of two segments fringed with hairs and terminating in two conical
appendages, between which are two cylindric perforated tubes : these communicate with
the respiratory organs. The larva, as well as the imago, is obliged to rise to the surface to
obtain a supply of air.

FAMILY DYTICIDZ. 55

2. The Gyrinip& are provided with short clavate antenne : body oval and convex, as
in the Dyticipx, but more glossy. The legs are unequal in this family : the anterior ones
are long, and the four posterior are short, compressed, and formed for swimming. The
larve differ also from those of the Dyricipom, by having on each side of the fourth and
seven following segments a membranous conical appendage, which is flexible and bearded
at the sides : these appendages are subordinate to the respiratory organs, with which they
communicate by a small tube.

Dyticide.
Halipides.

Antenne ten-jointed ; posterior cox dilated into a large shield, covering the base of the
legs.
Genus HALIPLUS (Crarrv.). Cyemmorus (TIl.).
Maxillary palpi with the last joint very minute and subulate.

Hauretus 12-puncrartus. ( Plate xx, fig. 15.)

Head, thorax and elytra buff-colored. Elytra with twelve black spots, some of which are

confluent ; inner margin and anal extremely black ; thorax with a lunate black or
brown spot on its anterior margin ; eyes black.

HALirLus IMMACULATICOLLIs. (Plate xx, fig. 16.)
Insect buff-color : elytra with ten black spots, the central comparatively large, and com-
mon to both elytra ; thorax brown, immaculate.

Gexus DYTICUS. Dyrtiscus ( Linn.)

* Anterior male tarsi patellated ; claws didactyle; maxillary palpi with the second and
third joints equal’ (Westwoop).

Dyticus HARRISII. ( Plate v, fig. 10.)
Color black softened into olive ; front or forehead Inteous ; lateral margins of the thorax
Iuteous : upon the latter it diminishes posteriorly, and extends to the under side of
the same ; beneath, the thorax and first pair of legs are luteous : posterior legs long,

and furnished with two dense rows of brown cilia. Length one inch.
This species is rather common in small ponds of water, where the bottom is clear and
sandy : a locality where it may always be found, is at the head springs which supply the

city of Albany with water.

Tus subfamily is composed of insects which frequent water : their eo
and narrow, and their Jegs are formed for walking. They have un oval body, more
convex, and the posterior part of the thorax is as wide as the abdomen or bees of they
The antenne are short ; mandibles robust and notched at the tip, with their inner
ciliated. As they frequent the water, their entire surface, as in Pauses, is covered with
cilia to retain air; or, as in Evotts, in part ciliated, for the same object. This arrangement
gives them oxygen when immersed in water.

The two genera Panyus and Evos are regarded as belonging to two sabfamilies ; but
being closely related, it is sufficient for our purpose to place them in juxtaposition.

Parsxvus FASTIGIATUS. ( Plate xxiii, fig. 7.)
Body oval convex ; head retracted : color a drab brown ; thorax and elytra covered with
a coat of fine appressed hair ; legs reddish on their outer sides.

Evaus crenatis? ( Plate xxiii, fig. 9.)
Body convex, angulated, punctate, acute behind ; thorax and elytra marked with four
black dots; end a faint reddish stripe upon each ; legs reddish.

Silphides,

Tue wide depressed or flat form of body is a reliable characteristic of a part of this group.
‘They are always present in putrescent animal matter : wherever a carcase of an animal is
decaying, or even a bone not perfectly bleached, there we find numbers of the silphides.
The Necrornons, however, is much less depressed or flattened than the genus Stcpma,
and seems at first sight to constitute a distinct group by itself. The latter are sometimes
called sexton beetles, from their habit of burying all the smal] dead animals which they
meet with. In this Iabor, they exhibit a great amount of industry and perseverance, as well
as a high grade of instinct in seemingly devising means to accomplish an end.

The anatomical characters of these beetles, as given by Westwoop and others, are :
Antenne thickened at the tips; palpi filiform and slender; labrum transverse and
emarginate ; maxille bilobed, the inner armed with a hook ; mandibles strong and exsert,
especially in Necrornoxes ; thorax orbicular or semicircular, forming a kind of shield for
the head ; tarsi five-jointed, the fourth nearly equalling the others.

Gexes NECROPTIORUS (Fan., Leacn, Onrv.).
€ Body oblong ; elytra truncate ; club of the antenna large, round, four. jointed, perfoliate ;

* maxille unarmed ’ ( Westwoop)

FAMILY DYTICIDAS. 57

NecropHorus AMERICANUS (O].). ( Plate xxii, fig. 8.)

Head, thorax and elytra black, shining ; forehead marked with a cordate yellowish brown

spot ; thorax brown, except a black dentate border : elytra marked with four ir-

regular yellowish brown spots, the anterior prolonged upon the anterior margin ;

margin grooved, and of the same color as the spots : club of the antenne yellowish
brown, black beneath : anterior tarsi ciliate ; cilia yellowish brown.

This large conspicuous beetle presents certain variations of color and marking, which
indicate a difference either in sex or species. The yellowish brown spots described above
are much darker in some individuals, while the forehead mark is rounded behind, square
in front, and behind and between the eyes there is a rufous spot which does not exist in
all. The thorax is curiously indented upon its border. Length 1} inch. °

NecropHorus ToMENTOsus ( Wb.). ( Plate x, fig. 2.)
Black : elytra crossed by two rufous bands, black beneath ; thorax and sides pilose ; club
‘of the antenne black. Length about three-fourths of an inch.
This species is quite hairy, especially upon the thoracic plate : hairs greenish.
Common in July in New-England and New-York.

NecropHorus pyemevs ( Rich.). ( Plate xxii, fig. 5.)
Black : elytra marked with four angular bright red spots. Length rather more than half
an inch.

The Necropuaca perform the part of scavengers in destroying and burying carrion. WV.
tomentosus takes its trivial name from the yellow hair upon the prothorax. The family
Deristip& is also destructive to animal matter : they deposit their eggs in it ; and when
they are hatched, they feed upon it; but the dermestes attack and devour any animal
food, whether in a state of decay or not. It is supposed that the perfect animal, however,
prefers flowers to meat, though we always find it busy in the latter.

SILPHA AMERICANA, ( Plate xx, fig. 3.)

Depressed, black ; thorax yellow, with a subquadrangular black spot in the centre ; elytra

knobby, black or brownish black tipped with yellowish ; outer angles truncate, or

Depressed, black : thorax smooth and shining ; elytra marked posteriorly with a short
rufous band, and traversed by three strongly marked sharp ridges, black beneath.

Nitidulide.

Tus family has the habits in part of the silphide, as some of them are found in putrid
animal matter, or feeding upon mushrooms ; others, however, frequent flowers. They are
oval, broad, and much depressed ; and they have filiform antenne, terminating in a short
elub of two or three joints. The thorax is transverse and emafginate : in some, the elytra
are short, leaving the abdomen exposed. They are small insects.

Gesus NITIDULA.

‘ Body oval, subdepressed ; thorax margined ; tibia compressed ; fourth tarsal joint bi-
‘lobed ; third joint of antenna longer than the fourth’? (Westwoop).

NITIDULA BIPUSTULATA. ( Plate xviii, fig. 1.)
Oolor of the body and thorax dull brown : central part of the elytra marked by a patch
of lighter brown ; margin light brown. Length about two-tenths of an inch.

FAMILY ENGID-E, 59

Engide.

Tue insects of this family are allied to the Nrriputipm and Dermestipe : from the former,
they differ by their elongate form and simple tarsi; and from the latter, by their highly
polished bodies, and more developed form of their mandibles ( Westwoop).

The Encipa subsist upon wood in a state of decay, or upon fungi, in some species of
which many individuals may be found. I procured a large number of individuals belonging
to this family, in the gelatinous sap which was slowly oozing from a wound in the trunk
of a yellow birch : they are also found under the bark of trees,and never feed upon living
or dead animal matters.

The anatomical characters, as given for the Excinm proper, are : Antenne short, cla-
vate, ten- or eleven-jointed ; maxillary palpi equalling the lobes of the maxille ; labium
advanced in front of the mentum ; Jabrum transverse ; mandibles bifid at the tip ; tarsi
in some four-jointed, in others five. .

Geyxus ENGIS ( Larr.).
‘ Body long ovate, subconvex ; tarsi five-jointed, the fourth joint short ; maxille bilobed ;
‘club of the antenne short, broad, flattened, three-jointed ’ (Wrsrwoop).

ENGIS FASCIATA. . ( Plate xxiii, fig. 2.)
Thorax black : elytra brick-red, traversed by a broad black belt; posterior extremity
black ; inner angles of the elytra black, terminating in a partial crossbar. The pro-
portion of black and red upon the elytra is nearly equal.
These insects inhabit fungi, or decaying wood under the bark of trees : they are not,
however, specially injurious to trees.

Genos IPS (Hersst). |

The body is oblong and subdepressed ; tibia broad and serrated ; tarsi five-jointed ; lobe
of the maxilla broad.

Ips FASCIATUS. ( Plate xxiii, fig. 4.)

Body oblong, subdepressed ; thorax and head black ; elytra black, with two yellow an-

gular spots upon each ; legs short; tibia broad, subserrated ; tarsi pilose. Length

terminal extremity black ; outer and anterior angles black. Insect shining.

Ips QUADKISIGNATA. ( Plate’ xxiii, fig. 6.)
Head and thorax black : elytra black, with two an spots on each elytrum, shining ;
the posterior spot is somewhat oval ; upper and outer angles black.

Ips pirUsTULATus. ( Plate xxiii, fig. 8.)
Color brown, dull ; elytra marked with two large yellow dots. Length about two and a
half lines.

Cucujides.

Gesxus CUCUJUS. Cotyorem ( Herbst).
Antenne short, moniliform or clavate ; basal joint short.

Cucusus CLAVIPES. ( Plate xxii, fig. 2.)
Depressed, flat or compressed ; color uniform, inclining to brick-red ; abdomen below
dark, and nearly black upon the margins. Length about half an inch.

DERMESTES LARDARIUS. ( Plate xxii, fig. 5.)
Body oval, subeonvex, black, with a gray bar passing across the anterior part of the elytra,
in which are three dots on each elytrum.

The genus Deamestes is named from derma, a skin, with which the larve make great
ravages, eating the surface so as to cause the hair to fall off. The Dermestes lardarius com-
mits its depredations in houses, usually in furs, meat, pork, bacon (whence it is sometimes
called bacon bug), collections of insects, ete. when stored away without protection. It is
about one-fourth of an inch long, nearly black ; the base of the elytra ash-color, with
three small black spots.

This species is active in attaoking all animal collections of natural history : from this
depredator, they are best protected by arsenic. Articles of domestic consumption should
be preserved by preventative measures, such as enclosing hams in canvass and white-
washing them.

The Dermestes vulpinus is distinguished from the /ardarius, by having the elytra entirely
black, and the under sides and under parts covered with white seales. It is very destrue-
tive to hides, in which it is imported. In France, it has been observed to perforate walls
built of stone soft enough to be broken by the nail. It is found in America, Europe and
Asia.

There are several other insects which are destructive to skins, and to anatomical and
natural history collections : one of them is the Anthrenus museorum (Byrr. muscorum,
Linn.). It is not a native of this country : it is, however, replaced by the .?. destructor,

FAMILY STAPHYLINID. 61

Melsh., which is a short oval insect about one-eighth of an inch in length, of a fuscous color,
and marked by several waved whitish fasciz. The larva of another small and much nar-
rower insect, Dermophagus tarsale of Mesurier, is also very destructive to entomological
collections.

; Staphylinide.

Tue cheracteristies of the insects belonging to this family are, their long, narrow, and
depressed form; the shortness of their elytra, and hence the great exposure of the ab-
dominal segments. Their true wings are closely folded beneath the curtailed elytra, al-
though they are large when expanded. Their heads too are remarkably large ; and when
set out by their projecting mandibles, it is no easy matter to persuade oneself that it is
safe to catch them. Their antenns are not very conspicuous, but are sometimes enlarged
towards the extremity. The thorax is strong, and as wide as the first segment of the ab-
domen. From the shortness of the wing-covers, the abdomen is equally hard above as
beneath, and is not confined by them : it therefore admits of free motion, and is employed
as an instrument to assist in folding and unfolding the wings. When the insect is captured,
a curious organ protrudes from the extremity of the abdomen, consisting of two vesicles,
which are extruded at the will of the inseet, and from which it is not uncommon to per-
ceive that a peculiar vapor escapes that is by no means pleasant.

Wesrwoop regards this family equal in rank to the Carasma#, and susceptible of sub-
divisions of the same value : the name Bracuyrtyrra has been generally employed in
denoting it.

Grexus STAPHYLINUS (Liyy.).
‘ Body nearly glabrous ; antenne subfiliform, with the fourth and tenth joints subequal ;
‘thorax subquadrate’ (Werstwoop).

STAPHYLINUS VILLOsUs.
Head and thorax blaek and glossy : back, sides,and abdomen beneath villose, or covered
with a dense coat of hair; abdomen banded with greenish buff. Length six-tenths
of an inch.

STAPHYLINUS CYANIPENNIS. ( Plate xxxi, fig. 6.)
Head and thorax black and glossy ; elytra steel-blue ; abdomen hairy and black.

STAPHYLINUS CHRYSURUS. ( Plate xxxi, fig. 3.)
Above an olive brown, clothed with short yellow hair ; sides and extremity of the abdo-
men golden yellow; thighs black, except at their tips, and a dorsal line.

CHAPTER VY.

ORDER I. COLEOPTERA ( Continued). —

PENTAMERA.

Distixcutsueo entomologists have made two grand divisions of the pentamerous insects.
Some of the families of the first division have been noticed : the seecnd is equally im-
portant with the first, and admits of subdivision into natural groups or families ; but there
is some diversity of opinion where the lines bounding these families shall be drawn, and
also respecting the best terms for designating them. a

A plain and comprehensive subdivision into groups has been made by Srernexs : 1,
the CLaviconyes, which are characterized by the antenne terminating in a solid ball, or
a perforated one; 2, the Laserticounes, with the antenn@ terminating in a leafy or
Jamellated mass; and, 3, the Sexniconnes, having the antennae constructed so that the'r
whole length is toothed somewhat like a saw. The Craviconnes are divided into two
families : the first contains those insects which resemble the Linnean Genus Bynanus,
having straight claviform antenne, and called the Family Byraniox, Leach. The second
family have also claviform antenne, but each with a distinct elbow or angle.

The Byxanios are small beetles with short oval convex bodies, and generally pilose or
hairy : the elytra cover the body, and the legs ean be folded up; when alarmed, it folds
them together under its body, and then remains motionless, appearing like a seed, until
the danger is past. In this family the antenna become gradually clavate, and the club is
not solid. .

The second family of elavicornes takes its name from the Genus Histrn : hence the
family name Histeaine, Leach. In these, the antenns, instead of being straight, have a
sudden or short angle in them, or are said to be elbowed. They aresmall insects, hard and
shining or highly polished, and usually black : their forms are somewhat square, but still
possess considerable convexity ; their legs are more or less den‘a‘e,ond the two hind ones
are set widely apart; the elytra are short, and hence leave a portion of the abdomen
exposed. Their elbowed antenna, their polished surfaee and short elytra, clearly distin-
guish them from the byrrhidm.

GROUP LAMELLICORNES. 63:

The Lametiicornes received their name from the structure of their antenne ; the
extremity being a laminated knob, composed of three or more leaflike lamin, which open
and shut somewhat like the leaves of a book. The first division of this group consists of
the Scaranipes, the first section of which are named Coprophagi, from the kind of food on
which they subsist : they feed upon and live in ordure, or excrements of all kinds. The
ancients gave the name pillularia to certain species which have the curious instinet of
rolling the excrement into balls with their hind feet, and in which they have deposited
their eggs : when the ball has acquired a sufficient degree of solidity, it is prened into a
hole previously prepared for its reception.

A foreign species, the Ateuchus sacer, was an object of religious veneration and worship
among the ancient Egyptians. With them it was symbolical of the world, the sun, and the
warrior : of the world, from the globular shape of its balls, and perhaps also from the
progeny they contained ; of the sun, from the angular projections from its head in the
form of rays : the six legs havo five tarsi each, and hence they represented the days of
the month. The idea of the courageous warrior was imbibed from the supposition that the
species were all males. The Roman soldiers wore its image on their signets ; and it is said
that it is still a custom with the Egyptian women to eat them, to render themselves pro-
lifie : as the sun is the source of all fertility, so the eating of this symbol would impart
to them the same desirable quality. When we reflect a moment upon the attention which
these curious insects pay to their offspring, and the intense emotion they exhibit in rolling
their balls, a work which they prosecute until overcome by exhaustion, it is not at all
surprising that the ancients should have made them symbolical of the highest order of
qualities.

The Copris carolina closely resembles the symbolical beetle of the ancients, just referred
to. The Genus Copris makes its abode beneath the fresh excrement of the cow ; and hence
its hills of dirt are common in pastures, by roadsides, and other places where the cow is
kept. This insect, however, never rolls a regular ball, but collects a quantity into an ir-
regularly shaped mass. The true pi//udaria belong to the Genus Grorruprs, and a few
other allied genera.

The larva of the Gxoraurrs resembles that of the Merotonrna, being of a dirty white
color, soft, and, when not engaged in feeding, it lies coiled in a semicircle : they have
six scaly feet and a sealy head. Subsisting at first upon the magazine of food which the
mother has provided in the offal in which they are enveloped, they afterwards penetrate
into the earth, and feed upon roots. It requires a year or two for their perfection : they
are then transformed into nymphs; and another year passes, before they are ready to
become perfect insects.

The Lametticornes consist of ten families, each presenting some peculiarity in the
antenne, mandibles or maxille, by due attention to which the student will be able to
determine the position an unknown insect may occupy. The first of these ten families is

the Lucawinm, taking the fumily name as usual from one of the most important genera it
contains : in this instance it is the Lucanus dame, an elongated stout insect, and furnished
with strong and projecting mandibles, especially in the males. Their antennw are elbowed,
and the terminal knob is constructed after the fashion of the teeth of a comb, or is peetinate :
they consist of only three terminal teeth, somewhat separated from cach other, but near
enough to come within the definition of emelliccra beetles (See Plate xii, fig. 7, m, 0).

The second division of the Lascenticoayes embraces all those beetles whose antenne
terminate in leaves or lamell, consisting usually of three pleces, which fold together or
lie in contact like the leaves of a book, This division reeeived the name of Petalocera from
Dement : it contains many insects which belonged to the genus Scorabaus of Lixyrre.
The antenne differ from those of the insects of the Family Lucaxipx, inasmuch as they
are not elbowed ; and the number of joints is variable, eight, nine or ten. In some groups,
the males are remarkable for their appendages upon the head or thorax, either in the form
of horns or protuberances. Some of the largest insects belong to this division.

The habits of the insects of this division are various : some, and probably the majority,
feed upon refuse matter, some upon excrement, some upon leaves, and others upon flowers.
Their larve are conspicuous for their size : they are of a soft consistence, of a whitish
color, and furnished with strong mandibles, We find them in the vegetable mould, usually,
coiled, or in decaying logs. They have fourteen rings, including the head, and the rings or
segments are transversely grooved.

From the diversity of character which exists in this great division, it has been subdivided
into ten families. The first is the Georaurine : their maxillary lobes are membranous, the
mandibles are porrected, and the elytra cover the abdomen ( Plate xii, figs. 1, 2, 3, 5, 8).

_ Their antenns have ten or eleven joints ; and their bodies are globose, or thiek and more —
or less rounded and full. Their habits are peculiar : they feed upon excrement, though
some are said to feed upon roots.

The Scananmio® constitute the second family of this great division. They are furnished
with a shieldlike extension in front, the ¢/ypeus, which extends over the mouth ; and their
antenne are eight- or nine-jointed, with the end terminating in a three-leaved club. The
middle legs are inserted more widely apart than the others : the posterior legs are far
behind ; the seutellum is not present; and the elytra are shortened behind, leaving the
abdomen exposed. The claws are minute, and the anterior tibie are expanded and tri-
dentate externally, armed with a single spur. The insects feed upon excrement, and the
greater proportion of the family reside in warm climates. They are many of them ball-
rollers; and to aid them in this work, their hindlegs are long and inserted far behind,
which gives them a grotesque appearance when walking. They fly mostly by day. ( Plate”
xii, figs. 5, 7.)

The third family of Macteay is called Arnopups®. They too are excrement-eaters : they
are oval and rounded at the posterior extremity. In this family we find the minute instead

GROUP LAMELLICORNES. 65

of the large beetles, and they belong to temperate climates : the legs are placed at equal
distances apart; the scutellum is distinct; the clypeus is entire, and the antenne are
nine-jointed. The body is more elongated than in the former family.

The fourth family is small, or of a moderate extent : it is the Trocinm of Macreay.
The insects are of a medium size, ovate or gibbous, and the elytra are inflexed at their
sides. The scutellum is distinct, and the anterior tibize are imperfectly toothed. The head
is deflexed ; thorax short, posteriorly situated, and the anterior angles are advanced : the
elytra are rugose. (Plate xxiv, figs. 1 & 3.)

The fifth family is the Dynastipm of Mactray. The insects of the family are gigantic,
and the males are very strongly identified by prominences and horns upon their heads or
thoraces. The jaws are powerful, horny and prominent, and furnished with two teeth ; the
scutellum is distinct ; the antenn are ten-jointed, and the elytra are shortened behind,
leaving the abdomen exposed : the color is a rich chestnut-brown. The insects reside in
rich vegetable matter and in putrid offal, and the family belongs to tropical regions.

The Rutizip& constitute the sixth family, which, for the most part, are brilliantly
colored. The males are destitute of horns, in which respect they differ from the preceding
family. The antenne are ten-jointed, club three-jointed : the mandibles are short, but
project more or less from beneath the coriaceous labrum ; they are also notched on the
outside near the tip. The elytra do not cover the abdomen.

The seventh family is allied to the preceding : it has received the name of Anorto-
GNATHID#, and is composed, like the Dynastipa, of foreign species.

The eighth family, the MeLotontuip2, constitute a well-known group, which contains
numerous indigenous species, with forms as delineated on Plate x, figs. 4 - 6, 9. They are
ovate thin beetles, sometimes scarcely thicker behind than before. The labrum is divided
into two lobes transversely ; the mandibles are strong and horny, the internal margin acute
at the apex. The clypeus is separated by a transverse suture, which runs just before the
eyes : antenne 9 — 10-jointed, terminated by a knob composed of a variable number of
lamin (from 3 - 7), variable also in form. The anterior margin of the mentum is notched
or emarginate. Some of the species are large ; but the colors are not brilliant, the surface
being often pubescent and dull. The common horn bectle, or the goldsmith beetle, which
fly about in the evening in the months of June and July, may well represent this family :
they feed upon flowers or leaves, and are sometimes injurious in this way.

Passing the GLarnyrip», the ninth family, which are all foreign to us, we reach the
tenth and last family, the Cerontp™, a group which holds ebout the same place in the
scale of importance as the Merotontnip%. The antenne are ten-jointed : the labrum is
concealed beneath an emarginate clypeus ; the mandibles are comparatively slender, lan-
ceolate ; the mentum is pitcher-shaped, and conceals the Jabium ; the secutellum distinct :
the elytra do not cover all the abdomen. The insects feed upon flowers, and hence do
considerable mischief : their forms are delineated on Plate xii, figs. 4 - 6.

This species I have been unable to refer to its proper name. “The G. microphagus is
dark piceous above and beneath, and the legs are violaceous.”

GEOTRUPES SPLENDIDUS. ( Plate xii, fig. 3.)

Splendent green; purplish beneath. Thorax rather thickly punctured, and confluent on

the sides ; seutellum smooth, or with two or more punctures ; elytra subtuberculated

near the outer basal angle, angle somewhat rounded, and their surfaces are marked

by rounded ridges punctate in the grooves : body beneath clothed with brown hairs.
Length six-tenths of an inch.

Genus COPROBIUS ( Larr.).

Body ovoid; thorax dilated in the middle; scutellum none * abdomen nearly square ;
clypeus bidenticulated.

Copropivus L&VIs.

Medium size : color dull black, finely punctured ; elytral lines obsolete. The insect has a
submetallic hue in some lights, but is generally dull. There are about eight obscure
lines upon each elytrum : beneath, the body is naked, or destitute of hairs.

This insect is more common here than the Geofrupes. Common in June and July, when
they may be seen engaged in rolling a ball of dung containing their ova, and which they
finally bury.

Arevcnus sacer is a much larger insect, belonging to an allied genus, and is the sacred
Scarabeus which entered so largely into the mythology of Egypt.

All these species fulfil an important place in the economy of creation ; a fact which is
more obvious in tropical regions than in the north.

This insect does not roll up a ball, but makes a collection or heap of soft and fresh
manure, in which the eggs are deposited. It penetrates quite deeply into the ground be-
neath the droppings in pastures and by the roadsides.

Trogidae.

Trts is a family embracing but a few genera : they are ovate and gibbose, with inflex
elytra. The head is deflexed, the thorax short and transverse, and the surface of the elytra

rough. The antenn are nine- or ten-jointed, and the extremity is formed of three leaves

somewhat distant from each other ; the labrum is coriaceous and exserted ; the labium is

concealed by the mentum ; the mandibles are horny, and sometimes toothed.

This family is allied to the Grorruripx. The most reliable information is that they feed
upon carrion, or decaying animal matter, being found in the careases of dead animals :
they have also been found in rotten wood, and at the same time they are known to inhabit
sandy places under ground. Some of the family are apterous.

globose ; the next five are short, and the head is composed of three lamine in contact.
The clypeus is frequently horned, as well as the thorax : head subtrigonal ; elytia
truncate, leaving the end of the abdomen bare. The body is large and thick, the legs
strong ; tibize broad and dentate.

This singular family have some of the habits of the Georruripm : that of subsisting
upon and in the excrement of animals, and decaying refuse matter from the vegetable
kingdom.

Puyttoruaca varioLosa (Knoch.). Melolontha variolosa ( Hentz).

This species differs essentially from the foregoing in the form and structure of the
antenne, the knob consisting of seven curved elongate leaves. Its color is light brown,
with irregular depressions upon the elytra, which appear like accidental flexures or in-
dentations made by some external force ; it is clothed with long yellow hairs upon the
breast. The elypeus is extended and reflexed, and the sutural line is before its middle.

FAMILY MELOLONTHIDA. 73

The hairs, both upon the thorax and elytra, are arranged in four rather interrupted lon
gitudinal belts. Length eight- to nine-tenths of an inch.

This species I had not observed in the vicinity of Albany till this year, 1853 : many
individuals have been taken.

It may be remarked that most of the species of this genus are much alike, although
generally smaller than that figured. The color varies from yellowish brown to chestnut,
according to the species. The breast is more or less hairy, and the elytra are in some cases
sparsely furnished with erect hairs. In the larva state they feed upon the roots of grass,
and probably of grain, and thus they commit great hayoe upon pastures, whilst the adult
insects live upon the foliage of various plants.

These beetles are well known in the country by the name of hornbugs, and become
troublesome by flying into the open windows where a lamp is burning. Their proper name
is May beetle, a designation implying the time of their appearance among us. They are
injurious both in their larva and perfect states : in the former, by their depredations upon
the roots of grass and other herbage ; and in the latter, by the destruction of the young
and tender leaves of fruit and other trees. They are supplied with strong jaws for cutting
the leaves of plants, for which they are admirably fitted ; and their feet are strong, and
fitted for digging in the soil after their transformations are effected. They were formerly
included in the Genus Metotonrna.

Maybugs have rarely been sufficiently numerous to inflict serious injury upon the
farmer : the Hon. Mr. Bartow, however, records an instance where they did much da-
mage in Madison county, in 1849 and 50; they ate the leaves of the cherry, elm, apple,
butternut, ete., showing that they are by no means restricted to our cultivated fruit trees.
The most effectual method of destroying them was to kindle fires at night in the immediate
neighborhood of the trees they were injuring : attracted by the light of the blaze, thou-
sands were destroyed with little difficulty, or at a trifling cost. Shaking the trees to dis-
lodge them, was an effectual means of turning their attention to the light. They appeared
the last of May and first of June, and continued from eight to twelve days.

Another instance is related by Dr. Fircu in the Journal of the New-York State Agri-
cultural Society, where the Phyllophaga quercina appeared in great numbers and suddenly.
He states that on the farm of Mito Incauspe, an orchard, consisting of about seventy plum
together with many cherry trees, had their limbs stripped of leaves, buds, ete. while they
were in bloom : the bugs were hatched out in the course of two nights, and completely
destroyed all hopes of fruit for the season, even if the trees themselves survived defoliation.

The duration of the individual life of this insect is short, a week or two being the term
during which it lives : there is, however, a succession of individuals of the species, so
that the period which they remain is more than a month. After the pairing of the sexes,

[ Aericotturat Rerort — Vot. v.] 10

the male soon dies, and the female perforates the soil to the depth of a foot, where she
deposits her eggs ; they are then abandoned, and she retarnso the surface to

short time, when sho also perishes. The eggs are sald to hateh in about fourteen days. The
grubs are whitish, and provided with six legs situated near the head, and a pair of strong
jaws ; their heads are brown. These are the grubs that are frequently ploughed up in old
fields, of a grayish white color, an inch or more in length and a quarter of an inch thick :
thoy lie flexed in the form of a circle. They live during the summer near the surface,
subsisting upon the roots of plants, which they devour in large quantities : as winter
approaches, they deseend below the reach of frost, where they become torpid. Three or
four seasons are spent in this way, till finally they form a ball of an oval shape, in which
they enclose themselves and undergo their transformation.

The ravages of this grub may be much diminished by allowing crows and jays to
frequent the grounds infested by them : indeed it is the most feasible way of getting rid
of them; and although most farmers and gardeners carry on an exterminating war with
crows and blackbirds, yet these blackcoated vagabonds, as Witson calls them, are by no
means such great rascals as they are represented : they have redeeming qualities, and the
destruction of grubs and wireworms are real benefits which they confer upon the farmer.
The beetles themselves are devoured by skunks.

The beetles of this genus have been very abundant at distant intervals : almost in-
credible accounts are given of their numbers, especially of the European species.

Among the numerous remedies recommended for destroying the larva, ploughing, no
doubt, would have the effect of throwing many of them within the reach of frost ; but if
done too early, they would have time to bury themselves again. The larve and perfeet
insects are frequently seen when the ground is broken up in the spring; and many are
then destroyed by crows and blackbirds, which follow the ploughman to gather whatever
may be exposed suitable for their sustenance ; they are also destroyed by foxes, weasels,
owls, and, according to Dr. Hanars, the skunk. ;

The following extracts are from Lovupoy’s Magazine of Natural History, Vol. vi, p.
142 -4 : the rook isa species of crow.

‘A strong prejudice is felt by many persons against rooks, on account of their destroying
grain and potatoes ; and so far is this carried, that I know persons who offer a reward for
every rook that is killed on their land; yet so mistaken do I deem them, as to consider
that no living ereature is so serviceable to the farmer, except the live stock he keeps on
his farm, as the rook. In the neighborhood of my native place is a rookery in which it is
estimated there are ten thousand rooks; that 1 1b. of food a week is a very moderate al-
lowance for each bird; and that nine-tenths of their food consist of worms, insects, and
their larve : for although they do considerable damage for a few weeks in seedtime and a
few weeks in harvest, particularly in backward seasons, yet a very large proportion of
their food, even at these seasons, consis!s of insects and worms, which (if we except a few

FAMILY MELOLONTHIDE. 75

acorns in aufumn) form at all other times the whole of their subsistence. Tere, then, if my
data be correct, there is the enormous quantity of 480000 Ibs. or 209 tons of worms, insects
and their larvae, destroyed by the birds of a single rookery ; and to every one who knows
how very destructive to vegetation are the larve of the tribes of insects (as well as worms)
fed upon by rooks, some slight idea may be formed of the devastation which rooks are
the means of preventing. I have understood that in Suffolk, and in some of the southern
counties, the larvee | of insects allied to Lachnosterna| are so exceedingly abundant that
the crops [of grain] are almost destroyed by them, and that their ravages do not cease even
when they have attained to a winged state. Various plans have been proposed to put a
stop to their depredations ; but I have little doubt that their abundance is to be attributed
to the searcity of rooks, as I have somewhere seen an account that rooks in those counties
are not numerous.

‘A flight of grasshoppers visited Craven, and they were so numerous as to create con-
siderable alarm among the farmers : they were, however, soon relieved from their anxiety ;
for the rocks flocked in from all quarters by thousands and tens of thousands, and devoured
them so greedily that they were destroyed in a short time.

‘Tt was stated in a newspaper a year or two baele, that there was such an enormous
quantity of caterpillars upon Skiddaw, that they devoured all the vegetation on the
mountain, and people were apprehensive that they would attack the crops in the enclosed
lands ; but the rooks, having discovered them, in a very short time put a stop to their
ravages.

‘An extensive experiment appears to have been made, the result of which has been the
opinion that farmers do wrong in destroying rooks, jays, sparrows, and indeed birds in
general,.on their farms, particularly where there are orchards, That birds do mischief
oceasionally, there can be no doubt; but the harm they do in autumn is amply com-
pensated by the good they do in spring, by the destrnetive hayoc they make among the
insect tribes. The quantity of grubs destroyed by rooks, and of caterpillars and their grubs
by the various small birds, must be annually immense. Other tribes of birds, which feed
on the wing, as swallows and martins, destroy millions of winged insects. Even some,
usually supposed to be so mischievous in gardens, have actually been proved only to
destroy those buds which contain a destructive insect. Ornithologists have of late de-
termined these facts to be true ; and officers would do well to consider them, before they
waste the public money in paying rewards to idle boys and girls for the heads of dead
birds, which only encourages children and other idle persons in the mischievous employ-
ment of fowling. On some very large farms in Devonshire, the proprietors determined, a
few years ago, to try the result of offering a great reward for the heads of rooks ; but the
issue proved destructive to the farms, for nearly the whole of the crops failed for three
succeeding years, and they have since been Jorced to import rooks and other birds to re-stock
their farms with?

Large, golden yellow and immaculate ; seutellum and thorax give a green reflexion,
brassy in certain lights, Elytra terminated by 6 CORDS Seg SaaS ew eer

minenee behind, densely haired beneath.

It is one of the most common and beautiful beetles of this country. It takes its —
name /enigere, wool-bearing, from the dense woolly coating with which its abdomen and
parts beneath are supplied ; it is also called the goldsmith beetle, from its beautiful color
above ; though this name is likewise applied to the Gymnetis nitida, which is about the
same size, and of a greenish color margined and varied with fulvous. It may be reeognized
by wanting the triangular scutellum at the inner base of the elytra, this portion having
bo apparent juncture with the prothorax.

The “reoda is about nine-tenths of an inch long, broad oval in shape, of a lemon-yellow
color above, burnished like gold on the top of the head and thorax : the underside of the
body is copper-colored, and thickly covered with whitish wool ; and the legs are brownish
yellow, or brassy, shaded with green.

‘These fine beetles begin to appear in Massachusetts about the middle of May, and
continue generally till the twentieth of June. In the morning and evening twilight they
come forth from their retreats, and fly about with a humming and rustling sound among
the branches of trees, the tender leaves of which they devour. Pear-trees are particularly
subject to their attacks ; but the elm, hickory, poplar, oak, and probably also other kinds
of trees are frequented and injured by them. During the middle of the day they remain
at rest upon the trees, clinging to the underside of the leaves ; and endeavor to conceal
themselves by drawing two or three leaves together, and holding them in this position
with their long unequal claws. In some seasons they occur in profusion, and then may be
obtained in great quantities by shaking the young trees on which they are lodged in the
daytime, as they do not attempt to fly when thus disturbed, but fall at once to the ground.
The larve of these inseets are not known : probably they live in the ground, upon the
roots of plants.’ Harris’s Report, p. 22 -3.

This insect seems to be local in its distribution, as it oceurs plentifully in the publie
snares of Philadelphia, whilst it is rare in the interior of Pennsylvania.

as described above ; the thorax is darker than the elytra; beneath, the body is brassy
green. They ‘ly by day, and feed almost exclusively on the leaves of the grape, and hence

may prove injurious to the vine : still their numbers are rarely such as to render them a
formidable foe. The only mode of destroying them, which is recommended, is to pick them
off and crush them under the foot. The larve are scarcely injurious, inasmuch as they
live in rotten wood, as stumps of trees, and such trunks as are decaying upon the ground :
they may be regarded rather as beneficial, by aiding the entire destruction of that which
only cumbers the ground.

The perfect insect prevails during the months of July and August.

P. macutarta, an allied species or variety, has the legs and extremity of the abdomen of
the same color as the upper parts. ‘These beetles fly by day, but may also be seen at the
same time on the leaves of the grape, which are their only food : they sometimes prove
very injurious to the vine. The only method of destroying them, is to pick them off by
hand, and crush them under foot. The larve live in rotten wood, such as the stumps and
roots of dead trees, and do not differ essentially from those of other searabeans’ ( Harats,

absent.

FAMILY MELOLONTHID. 79

The rosebug, or cherrybug, as it is called, is very destructive. Its generic name Macro-
dactylus, is derived from the length of the feet ; and its specific or trivial name subspinosus,
from an incipient spine or swelling upon the sides of the prothorax. It is of a dull yellow
color, about three-eighths of an inch long, and appears in great abundance in the spring,
destroying roses and the blossoms of various plants, as well as the foliage of fruit trees,
including the apple, cherry, plum, and that of the grape.

Dr. Harris has the credit of being the first to give a satisfactory history of this insect,
as published in his Report.

I have been in the habit of destroying this insect, as well as the Eriosema mali, or the
appletree blight, by hand-crushing. When there is little or no grass beneath the trees, they
may be beaten down and crushed with the foot; the best time being the morning, when
they are somewhat torpid. They may be collected upon sheets, or in vessels with a little
water to prevent their escape ; to be subsequently burned or scalded. Plants infested should
be visited once or twice a day, and every effort made, by destruction of the present brood,
to diminish that of the next season.

sinuate behind for the reception of the seutel ; seutel an isosceles triangle ; elytra
light brown with black spots scattered over their disks and sides, margins sinuate,
behind truncate, exposing the abdomen; legs hairy and brown; abdomen brown,
glossy.

The thorax is more densely clothed with hairs than the elytra ; the latter are sprinkled
with spots and dotswhich are nearly black, some angular, and others sinuate. Color of the
abdomen and legs nearly uniform : the thorax is also spotted beneath the hairs; the
sinuated base is naked and fuscous. Length six-tenths of an inch.

This insect appears twice in the season ; first in March.or April, and last in September :
the latter, as Dr. Haxxis supposes, is a newly hatched brood, as at no time during the
summer is an individual to be found.

These insects appear upon various autumnal flowers, as the goldenrod, in search of
pollen and honey, and are fond of the sap and sweet juices of trees and plants. They are

charged, however, with frequenting orchards and feeding upon the ripening fruits : par-
ticularly do they select the best peaches, which, if they do not entirely devour, they
greatly injure by biting them. The distinguished naturalist last above named mentions that
he has taken a dozen from a single peach.

When cold weather approaches, they are supposed to secure themselves in some shel-
tered place, and pass the winter. The March brood, as I have often observed, appear to
issue directly from the ground ; and at numerous places they may be seen in numbers,
flying low, and hovering over the ground like humblebees, upon whieh they alight and
are lost in the dead grass and leaves, or penetrate again into the earth.

The genera of this family are numerous, and are known as flower beetles. The European
species Cetonia (Epicometis) hirta is said to destroy apricot blossoms in Malta; and another,
Cetonia cardui, visits beehives,and destroys the wax and honey (Revue Zoologique, vii, 96).
Plates of lead, with small perforations for the bees, were put over the place of ingress;
but the cetoni# soon enlarged them : zine was then substituted, and found to answer as

a protection.

Ceronta ruxora ( Fab.). ( Plate xii, fig. 4.)
Body depressed, ovate. Head small, green above : thorax triangular and brilliant green,
margined with luteous ; its sides are also slightly dilated ; base slightly sinuons for
the reception of the seutel, which is an isosceles triangle and green. Elytra luteous,
sometimes they show a greenish tint, truncate and deflexed behind : at the deflexure
they are prominent ; the prominence terminates an obscure ridge which runs from the
shoulders of the elytra; the suture is also elevated, so as to form a central ridge.
Behind, the abdomen is marked with four triangular mouldy spots : spots similar to
these extend along the sides of the abdomen ; legs luteons, glossy ; sides of the breast
hairy ; tarsi and base of the cubits brown, nearly black. Length six-tenths of an inch.
This insect, which is very common in Maryland, is not very numerous, as I have
observed, in New-England and New-York : it is more common in the paths in groves than
elsewhere.

CHAPTER VI.

oy ORDER I. COLEOPTERA (Continued).
PRIOCERATA.

Tue next subtribe of pentamerous beetles is named Priocerata by Mr. Westwoop (Serri-,
cornes, Latr.). They comprise those families whose antenne are short, or only of a moderate
length, with an equal thickness throughout, and generally attenuated at the tip rather
than thickened : they are eleven-jointed, but their peculiar characteristic consists in being
serrated upon their inside ; hence the name serricornes by Larner : in the males, they
are sometimes pectinated. The insect has two short robust maxillary and labial palpi :
body elongate and narrow ; elytra narrowed behind, covering the abdomen.

The Priocerata are divided into two sections, the Macrosterni and the Aprosterni, by
Westwoop. The first comprises the old genera Burrestis and Exarer, the consistence of
whose bodies is firm, and their forms elliptic and elongate, but narrowed behind : their
legs are short, and either partially or wholly retractile ; and their heads are short, and are
received into a cylindrical excavation in the prothorax, or in front up to their eyes. The
pectus advances beneath the mouth, and is also produced behind to a point.

These beetles, for beauty and splendor of coloring, are among the finest of the class of
insects : they are rich in the metallic hues which ornament their bodies and elytra. They
fly swiftly, but walk slowly, from the shortness of their legs. They make their escape,
when in danger of being captured, by falling suddenly into the grass and weeds.

The Burrestipx, or bupestrians, have an oval form, being widest behind the thorax and
obtuse before, but narrower behind and frequently acute : their bodies are also wider than
deep, with a thorax wider behind than before. The head, according to the typical character
of the family, is sunk into the thorax up to the eyes : the antenne are short, and serrate
on the inside. The thorax is widest behind, and fits very closely to the base of the elytra.
The legs are set widely apart, and are short, and hence their stand is firm : the soles of
the fourth joints of the feet are furnished with spongy cushions, and the foot terminated
with two claws : the seutel is small. The insects are rarely seen, except in hot sunny days,
when they may be found on fences, limbs of trees, or sides of houses, basking in the sun :
they never fly in the night.

[AcricuttruraL Report — Vo. v.] 11

Although the buprestidw are among the most elegant and beautiful of the coleoptern,
yet their Jarv@ are one and all more or less injurious to fruit and forest trees, The eggs of
the female are deposited upon the trunks and limbs of trees, and, when hatched, the young
grubs penetrate slowly through the bark ; and as they are often many years in coming to
maturity, time and opportunity is = for extensive injury : it is here they undergo their
transformation.

The larve of this natural family of insects have a very close resemblance to each other,
and hence a brief description of a single species will be sufficient to convey an idea of
their general characteristics. These larve, then, are white or yellowish white, rather long,
narrow and somewhat flattened, and furnished each with a small brown head sunk into a
suddenly and abruptly widened out thorax, conveying at first view the impression that the
head is very large, whereas it is only two or three of the last rings that are thus suddenly
widened out and enlarged ; the upper jaws are supplied with three black teeth. There are
no legs or other apparatus for locomotion, except two tubercles placed on the under side
of the second from the thorax. When drawn out of its burrow, the larva progresses by a
kind of wriggling motion, frequently rolling over, though not so often as the more eylin-
drical larva of the boring coleoptera. They are found both beneath the bark and in the
wood : under the bark, they lie partly coiled, or in the form of a semicircle. The pupa —
bears a very close resemblance to the perfect insect : it is found very near the outer
surface of the bark, so that when the transformation is complete, the insect has only to
perforate a thin scale of bark to escape from its prison into open day.

The oaks, hickories and pines are the kinds of trees most usually infected with the
bupestrian larve ; and, unfortunately, our knowledge of the ways and means by which
these larve may be destroyed are few and uncertain : the knife and wire are the only
infallible means to remove them, when once they are in possession of the premises. Our
preventive means, however, in the case of fruit, are more effectual ; such as scraping and
washing the trunk and large limbs, at those seasons of the year when they are known to
deposit their eggs. This kind of care and attention is rarely bestowed except in the spring,
which, so far as the family of borers is concerned, is perfectly ineffectual, as their eggs are
laid in the months of June, July and August. The perfect insect, though it may feed on
leaves, is comparatively harmless. There is, however, no provision which is so important
to keep in check the ravages of these and all other insects, as the preservation and pro-
tection of birds. The woodpecker in particular deserves the protection of the farmer, in-
asmuch as it is eminently successful in detecting the presence of the larve of the borers,
as well as very expert in dragging them from their burrows.

FAMILY BUPRESTID®. 83

Buprestide.

Gexus BUPRESTIS ( Lryy.).

Antenne subfiliform, serrated in both sexes ; basal joint elongate, subclavated ; terminal
one small. Palpi, maxillary subfiliform, the terminal joint slightly tumid ; labial,
minute, the labrum attenuated and slightly emarginated in front. Mandibles slightly
bifid at the apex : maxille small, somewhat bilobed at the tip. Head deflexed, short,
retuse : thorax with the posterior margin closely applied to the base of the elytra ;
the latter elongated, trigonate, entire or serrated : legs slender; tarsi with the pe-
nultimate joint bilobed ( Steruens).

A. Elytra dentate, and serrate at the apex.

Burrestis (CHALcopHORA) vireiica ( Drury). ( Plate v, fig. 5.)
Form oval : color dark brown and sometimes almost black, with brassy metallic reflec-
tions, more distinet beneath. Surfaces, above and beneath punctured ; above, sculp-
tured in interrupted parallel lines. Top of the head deeply indented longitudinally ;
indentation linear, and extending to the front. Thorax marked by three distinct
eminences, one of which is central. Elytra margined, sculptured or interruptedly
ridged ; base coarsely plicated ; outer angle rounded and serrate ; inner angle ter-
minated by a very short spine : the under side is furnished with a short whitish down.

It is nearly an inch in length, and quite robust.
The larve inhabit pine trees, to which they are very injurious. The perfect insect ap-

pears in June.

Buprestis FULVO-GuTTATA (Harris). B. americana ( Kirby).

Above black bronze; underneath metallic, glossy, punctured. Scutellum very small.
Thorax marked by waving transverse lines. Elytra granulated and ornamented with
six yellowish spots, but variable in number; tops rounded : underside of the ab-
domen, near the extremity, thickly punctured. Length 3- to 4-tenths of an inch.

The forelegs in this species are without teeth. It is the B. drummondi of the fourth vo-
lume of the Fauna Boreali Americane.
Found upon trunks of the white pine in June.

Burrestis (ANopiis) Fascrata ( Fab.). ( Plate v, fig. 1.)

Flattened above. Color fine brilliant green, nearly of one uniform tint, punctured above
and beneath. Mandibles stout and black : eyes black, ovate : thorax has four slight
depressions : scutellum small and triangular. Elytra finely lined, and marked by
transverse yellow bands : the first is a mere oblong transverse spot, near the middle ;

the largest, is an undulating band extending nearly across the elytrum, and the last
is a spot near the apex : the spots are surrounded with a black glossy border. The
apex has a steel-blue reflexion, and is bidentate.

This is one of the finest beetles belonging to this family : it varies in length from four
to six-tenths of an inch, The bands are variable in number : they are found some with
three, others with two, which is the most common, and still another variety bas only one.

[ I have observed, in some of the plates, the color of the figure is ms hace the
green too indistinct. |

Berrestis ——. ( Plate xxxi, fig. 11.)
Slightly depressed, widened posteriorly and punctured. Mandibles narrow, black ; beneath
purplish green :; eyes black : antenne green ; head and thorax green, eupreous and
metallic. Elytra bordered with metallic purple ; disk green, forming a middle lon-
gitudinal band; also marked with four elevated lines, truncate, and terminated at
the inner angle with a minute spine.

This beautiful species was found at Albany : its elytra are finely bordered with purple ;
the sutural line is divided into two near the base, and is dotted between. It appears to be

rare, as it is the only one I have seen in any of our collections.

Buraestis (Cunysonorinis) pentires (Germar). ( Plate v, fig. 2.)

Depressed or flattened, oblong oval, purplish copper-color above ; beneath copper-colored,

finely punctured. Surface covered in patches with a kind of shagreen. Thorax marked
with two elevated lines : elytra rounded behind.

This species is still less convex than the divaricata : its metallic hues are less distinct,
it is destitute of denticles at the apex of, the wing-covers, its eyes are much smaller, and
its mouth differently constructed. It inhabits the different species of oaks, and is not found
about our fruit orchards or gardens. It is the B. characteristica of Hannus ( New-England
Farmer, Vol. viii, p.2).

Burrestis (Cuaysonotinis) remorata ( Fab.). » (Plate y, fig. 3.)

Rather depressed. Color black and bronzed above, glossy and metallic beneath : upper

side the abdomen is green, punctured above and underneath. Eyes gray. Head is

marked with an elevated line, and covered with short whitish hairs in front. Elytra
rounded ; the posterior edge subserrate, or scarcely serrated.

This species is smaller than the dentipes. It has a well marked tooth inside of the thigh
of the forelegs. The elytra are rather shorter than the abdomen, and have an approach to
three pair of impressed gray transverse spots. It varies in size ; not exceeding, however,
half an inch in length.

I took many individuals of this species in Canandaigua several years since, in June,
upon a black oak, The foregoing species appear to be widely distributed.

FAMILY BUPRESTID. 85

B. Margin without serratures.

Burrestis pivaricata (Say). Cherrytree Buprestis. ( Plate v, fig 4.)
Convex ; greenish cupreous above, purplish and metallic beneath, confluently punctured
above and beneath. Elytra attenuate, divaricate or divergent at their tips : thorax
indented before the seutel ; scute] small and indented : elytra marked with lines and
with abbreviated elevations ; tips narrowed and prolonged beyond the abdomen, and
truncate and submucronate on the inner side. Length seven-tenths of an inch.
According to Say, it resembles the /urida of Fapricivs in general appearance.

Burrestis turipa ( Fab.).

Above dull brassy ; beneath brassy with purplish hues and bright, confluently punctured
above and beneath. Mandibles black : eyes dark brown or black : thorax dilated
before its middle, coarsely sculptured, and impressed with grooves rather than lines.
Elytra coarsely sculptured, marked with wider abbreviated lines, and connected by
branching ridges; behind they are slightly attenuate, projecting just beyond the
pointed abdomen, and terminated with two submucronate points.

This species differs from the former, in being destitute of lines, having fewer confluent
punctures, coarseness of the markings, less attenuated tips of the elytra, and their ter-
mination in two short spines instead of one. The larva is described by Mr. Harris as
destructive to the pignut hickory : it is of a yellowish white ; long, narrow, depressed
in form, and abruptly widened at the anterior extremity : head brown, small, and deeply
sunk in the forepart of the first segment; jaws three-toothed, black : no legs, nor sub-
stitutes except two small warts on the underside of the second segment of the thorax.

These grubs exist in the wood and beneath the bark, sometimes in great numbers : the
pupa resembles the perfect insect.

AGRILUs RUFICOLLIS, a member of the Family Burrestrp», was described by Professor
Havpeman in the American Quarterly Journal of Agriculture and Science, Vol. iv, p. 200,
fig. 1, as follows : ‘This little insect, so hurtful to the raspberry, is about three lines long ;
black, minutely punctured, thorax and front brassy ; front with a vertical impression :
a wide shallow impression across the thorax posteriorly, and another at the base of the
elytra. In this particular case, the knowledge of the appearance of the insect is not es-
sential, as far as the means of preventing its depredations are concerned, although it is
always interesting to know whence an injury proceeds.

‘In its larva state, Agrilus ruficollis lives at the expense of the cultivated Rubus (rasp-
berry), in the heart of which the pupa may be found in the month of May, the imago
appearing in June. The larva bores between the wood and bark, injuring the plant, and
causing a wide unsightly excreseence : it next penetrates to the pith, which it traverses
for two or three feet, finally excavating a cavity in which it undergoes its transformations.’

86 ORDER COLEOPTERA.

Elateridx.

Tue most distinct characters of this fumily are found in the form and structure of the
posterior part of the thorax and sternum ; the sides of the former are prolonged into 4
tooth, and the latter is produced into a spine which fits into a groove of the abdomen.
This arrangement of parts enables the insect, when upon its back, to spring upwards and
alight upon its feet : this is the only mode by which it can recover its standing, when
accidentally upset ; and from this circumstance these inspects are called spring beetles, or
snapbugs. Their anteune are short and filiform, and either serrate or pectinate ; the palpi
terminate with a triangular or reniform joint ; the mandibles are bifid at the apex : bedy
linear and depressed ; thorax with the hinder and lateral angles produced into a point ;
the margin is also grooved for the reception of the short antennw. The sternum is produced
behind into a spime, which fits into a groove in the base of the abdomen. The females are
furnished with a tripartite ovipositor.

In this family, as in the preceding, the head is received into the thorax deeply, and the
legs and antenne are short and slender.

The larve live upon the roots of vegetables, wood, etc., and are very injurious to corn
and herbaceous roots. They are known in New-York and New-England by the name of
wireworms, from their form and hardness : they resemble, however, a species of Iuivs,
which belongs to the Class Myriapopa, and should therefore not be confounded with it ;
a mistake which it is quite unnecessary to commit, as the myriapod has many feet, while
the wireworm has only six.

Although the elateridw, in their perfect state, are closely allied to the buprestide, yet
their larve have feet, while the larve of the latter family are destitute of them : so the
enlargement or dilatation near their heads is equally distinctive ; but there is one kind of
resemblance common to both, for they both live several years in the larval state,and hence
have abundance of time to do much injury. When a field becomes infested with wire-
worms, the indian corn and other cultivated crops are often entirely destroyed, and many
times require replanting. The larva eats either through the kernel after it is swollen, or
else through the young shoot. I have seen two wireworms in the same swollen kernel.
They attack grass, and all the cereals; and in consequence of their long continuance in
this state, the soil becomes infested with them. :

Soils which are the most infested with these larve are usually poor; and one of the
most effective modes that can be adopted in the cultivation of such land, is to enrich it.
Another mode which aids very materially in the extirpation of the wireworm, is to plough
late in the fall : it is supposed that by exposing the ground freely to the action of frost,
the larve must perish from cold.

FAMILY ELATERID. 87
’

Much has been said in the agreultural journals about the use of substances supposed to
be noxious to this insect, still there is no proof that any such remedy has been effectual.
Salt is usually relied on, but experience does not sustain its use. So far as salt contributes
to the amount of fertilizing matter, it will prove useful : beyond that, it is useless.

In gardens where these lary are common, Mr. Harris recommends the English mode
of extirpating them : this mode consists in baiting them with slices of potatoes or turnips,
which are scattered over the ground at night. Early in the morning the larve are found
above ground feeding upon the bait, when they are collected and destroyed.

Gexus ELATER.

This genus is characterized by the shortness of the antenne, which have a short robust
basal joint, the second and third joints small and subglobose, and with their margins
serrate upon their outer sides. Head small and retracted ; eyes small : thorax gene-
rally elongate, with the posterior angles produced : body only slightly convex, linear
elongate, sometimes subovate : legs short; tarsi simple.

Exarer (Axavs) ocunatus ( Fab.). ( Plate v, fig. 6.)

Form elongate, depressed. Color black, sprinkled with gray. Head small : thorax large,
quadrangular, and marked by two ovate black velvety spots situated rather in ad-
vance of the middle. Elytra are marked with slender lines ; posterior angles rounded.

The underside of the body, and of the legs, is covered with a gray mealy substance.

This singular beetle is found in midsummer upon walls and fences. It is one of our
largest beetles ; varying, however, from 1} to 1} inches in length : the largest specimens
are nearly half an inch wide. It is glossy black, powdered with white specks. The head
has a deep wide impression ; the prothorax is an oblong parallelogram, and the eyelike
spots are surrounded by a white ring. It is widely distributed, as I have found it south and
north. It appears, therefore, at different times in different latitudes : in North-Carolina,
the last of May ; in Pennsylvania, in June; and in New-York and New-England, in July
and August.

Mr. Hatpeman has found the larva of this beetle in ash trees in an incipient decay : it
is of various sizes. Mr. Harris has found the larva in old apple trees : it is not, therefore,
confined to a single species of trees. In old trees infested with them, it is recommended
to remove and burn them.

The larve are of a yellowish white color, or reddish ; and, when fully grown, the largest
individuals measure two and a half inches in length. The head is rough, brown and broad ;
the mandibles are strong and curved : they have six legs, and the last segment of the body
is furnished with a prop foot ; and the sides are armed with hooks and short spines.

According to Dr. Hannts, the females are more robust and larger than the males, and
the brevicornis of Say is identical with this species. The elytra are marked by about ten
distinct lines each : the legs are lighter colored than the elytra, and clothed with hairs ;
aud the prolonged outer angles of the thorax are exeurved.

elytra are punctured, and clothed in much the same manner as the foregoing. Length
less than half an inch. The lines of the elytra are only about seven in number, and
the hairs upon the upper side are arranged in lines or stripes.

It is found in the spring among the roots of grass, and it is observed by Mr. Hives that
its grub resembles the wireworm of Europe.

Eater ——. ( Plate v, fig. 7.)

This species was found dead ; it is much larger than the appressifrons, and of a light

brown color. I believe now that though it may not be a common species, still, as it is

faded, it will probably be a matter of doubt to what species it really belongs, and there-
fore I omit further allusion to it.

FAMILY LAMPYRID. 89

Lampyride.

Tue glowworms and fireflies constitute a part of this interesting family of insects. Their
bodies are elongated and greatly depressed, and soft : the elongation affects the abdomen,
the thorax and head being very short, and the latter concealed in the former. The females
are sometimes destitute of wings. Their colors are dull, though a considerable variety
exists, and the markings of the thorax are very peculiar, the ornamental colors consisting
of red and yellow combined with black. They are said to be voracious, and feeders upon
flesh, subsisting upon snails,ete. When alarmed, they fold up their antenne and feet, and
remain motionless : if disturbed, they fall into the grass or leaves. They are common on
fences and walls during the summer and spring. Some species fly into the windows at
night, being attracted by the light of the candle.

The family is characterized anatomically by the different authors as having filiform or
serrated antenne, with compressed joints ; the penultimate joint of the tarsi bilobed ; the
parts of the mouth small : mandible small, acute and curved.

Antenna subclavate, the three or four last joints being thickened : the head is more or
less retractile ; and the anterior parts, head and thorax, appear elongated, while the
abdomen is short. The thorax and body are both subrotund ; the last joint but one of the
tarsi, bifid. «

The family is composed of small but beautiful insects : they live in wood, and some-
times in the dried remains of animals, in which respect they seem to resemble the der-
mestide. Others frequent beehives, and feed upon the larve of the bee.

This species of Thanasimus is found upon the pine, both in the living and decayed state
of the tree.

The larva of one of the English species of CLerus, C. apiarius, is found in beehives, and
is highly injurious to the community, as it feeds upon the grubs of the bees. It is an
European insect, and is not known in this country ; but as other members of the family
may have the same habits, it is important that they should be found out.

are covered with hairs, and have a longitudinal stria filled with punctures. It is very
destructive when numerous, and is common to Europe and America : in Europe, it de-—
stroys stored wheat. Dr. Hatveman remarks that he has found it feeding upon the corn-
stalks used to line cases of insects in an entomological collection, in the month of Fe-
bruary. It seems to be a general feeder.

Lymexylonidae.

Tux destruction of ship-timber collected in dockyards, which so often happens, is fre-
quently effected by the Lymexylon navale, a species of insect belonging to this family, and
found in Europe. The cause of the damage was investigated by Lixxeus, at the request of
the King of Sweden; and when he discovered it, he reeommended immersing the timber
in water during the period when the female insect would be engaged in depositing her
eggs. Dr. Hanais describes an American species, or one belonging to the allied genus
“Hy ecetus.

Cures CAPITATA.

Golor black : head red or ferruginous, strongly ridged and transversely grooved, and
furnished with two prominent tubercles : thorax with three longitudinal ridges :
elytra strongly ridged, with two rows of punctures upon the back, and three between
the lateral ridges. :

FAMILY BOSTRICHID®. 93

Bostrichide.

Tuts family is distinguished by the cylindrical form of the insect, and by the front of the
prothorax, which is obliquely truncate. Tn this climate these insects are small, but within
the tropics there are some large species. They all infest forest trees, burrowing either
beneath the bark or into the wood. Th@power they possess of penetrating hard substances
is quite remarkable : seasoned timber is easily cut by them, and the lead of the roofs of
houses scarcely presents an obstruction. At Turin, cartridges stored in barrels were eaten
through, and the leaden balls gnawed an eighth of an inch in depth. The Bostrichus ca-
pucinus, the species on which the genus was first established by Georrnoy, has been found
gnawing type metal, which is considerably harder than lead. Their bodies are hard, and
generally black or of a dark rusty brown : the thorax is dilated before ; the antenne short,
and terminate in three large serrated joints. The larve are wood-eaters also, of a whitish
color, wrinkled above, and furnished with six legs.

Genus APATE. Bosrricuus (Oliv.).
Elytra spinose and retuse posteriorly : antenne with the second joint elongate, cylindric ;
terminal joints forming a perfoliated club. a

’
APATE BASILARIS.

Color black or dark brown : prothorax rough and punetured ; base of the elytra red,
punctured, and the posterior extremity obliquely truncate and furnished with three
teeth on each side. Length rather more than one-fourth of an inch.

This species is found as far south as Carolina. It perforates the shagbark hickory dia-
metrically through the trunk to the very heart, where it undergoes its transformations at
the bottom of its burrow ( Harris on injurious insects).

In Italy, the branches of the Morus mu/ticaulis are perforated by the pate sexdentate.
Many other species commit great havoc in forests, perforating the wood and burrowing
beneath the bark, by which the circulation of the sap is cut off.

Dr. Harpeman remarks in a manuscript note, that some strips of hickory which he had
employed to confine rose plants were destroyed in two years. The hickory is a tree that
suffers much from the attacks of boring insects ; and hoop-poles made of hickory saplings
are frequently destroyed, or rendered useless in a few months. Barrel hoops, made of this
excellent material, are often attacked, so that much inconvenience, if not actual loss, may
be the result. The proper remedy seems to be the immersion of the poles in water, or
storing them in cellars, during the deposition of the eggs. The latter mode is sometimes
adopted, but the former would have the advantage of destroying young grubs already
deposited.

o4 ORDER COLEOPTERA.

From the great and increasing value of the forests in New-York and Pennsylvania, it
becomes necessary to direct attention to these destroyers, that proper care may be taken to
prevent their increase. Although living trees are subject to attack, these insects have the
peculiarity of flocking to recently cut timber. On this account, infected trees should be
eut down and the bark subsequently removed and burnt, and the wood cut up and applied
as fuel, turned into charcoal, or immersed in water. Some European authors contend that
healthy trees are not attacked by these insects; al that when the attack has been com-
menced, it is an indication that the tree is in a state of incipient decline.

CHAPTER VII.

ORDER I. COLEOPTERA ( Continued).

HETEROMERA.

Tus division comprehends those insects in which the four anterior tarsi are five-jointed,
while the posterior pair are only four-jointed. They are mostly vegetable feeders, some
preferring leaves, others flowers, and others farinaceous matters. There is great diversity
in their color and habitat : some are beautifully ornamented, others dark and gloomy :
some prefer the light of day, and are found upon the wing sporting in the beams of the
sun ; others inhabit dark and gloomy places, retiring from day, and abiding in obscure
and tiple hen bel situations In these respects, however, we find elsewhere similar ar-
rangements and diversities.

The Herexomera are subdivided by Westwoop into two sections or tribes, the first of
which he calls Tracner1a. The head in this tribe is considerably dilated behind the eyes,
and then narrowed again, so that the thorax does not equal the broadest part of the head.
The body of the insect is also of a soft consistence, and the elytra are flexible, and folded
or overlapped on their inner margin. The Canrnanis is an example of this subdivision, as
to the character of the elytra and the softness of body and gay color of the insect.

The other great tribe or subdivision is the Arracuettra. In this tribe the thorax has the
width of the head, the posterior part of which is often concealed by the thorax. The habits
of the insects also serve to distinguish them from the first subdivision : they appear in
dull colors, rarely fly by day, and seek concealment in darkness. Among the ArRracHELia
we find the Genera Buars and Trenesrio.

The Tracneia comprise the Notoxide, Pyrochroide, Lagriide, Horiide, Mordellide.
Cantharide, Salpingide, (Edemeride, and Melandryide ; in all nine families.

The Arracnetia embrace only six families, namely, the Cistelide, Helopide, Tene-
brionide, Diaperide, Blapside and Pimeliide.

Tue contharides, or blistering flies used in medicine, are represented amongst us by the
allied genus Ericavta, having the same property of raising blisters. They are slender
soft-bodied inseets, with slender legs, the prothorax narrowed before, and the head large.
They are at times abundant upon potato vines, whence they have acquired the name of
potato fly, particularly the Epicauta vittota : it attacks the potato, convolvulus, and other
plants, from June to September. It may, with the other species, be collected with a muslin
bag having the mouth attached to a hoop; thrown into water to prevent escape, and
subsequently scalded and dried for the use of the druggist.

perfect state, frequent umbelliferous flowers.

Prrno americanus ( Knoch). ( Plate xxv, fig. 9.)
Brown, darker above, and slightly brassy or submetallic ; head and thorax darker than

the elytra.

Tenebrionidae, Blapsidae, and Pimeliidae.

ANATOMICAL CHARACTERISTICS. Tarsi and tarsal claws entire ; sides of the head parallel ;
antenne rather short, moniliform, and inserted beneath the widened margins of the head ;
mandibles short, triangular, tips bifid; internal lobe of the maxilla often armed with a
corneous tooth ; eyes oblong, and only slightly elevated.

Geyexat uantts. These families possess many similar habits : they avoid the light,
and live in damp places in cellars, basements, stables, ete., or upon the ground and under
stones in sandy places. The term ¢enebrio is derived from the latin, signifying darkness
( Westwoop). The colors are all dark brown or black.

In the Tenesnionips, the body is oblong ovate and depressed, or supplied with short
legs ; elytra free ; thorax square, and the head as broad behind as the base of the elytra :
the palpi are enlarged at the tip ; mentum narrowed at the base.

hence the body is less depressed than in the former family ; palpi three-jointed ; man-
dibles bifid ; internal lobe of the maxilla armed with a claw.

The mealworm is a hard smooth shining cylindrical larva about an inch long, which
lives upon flour, meal or bran, and is frequently very destructive to biscuits on shipboard.
It is said to pass two years in the larva state, when it appears as the Tenebrio molitor found
in Europe and America, and probably exported to other countries. In Europe, the larve
are raised in quantities to feed nightingales and other cage-birds. It is usually abundant in
grain-mills and granaries.

PSEUDOTETRAMERA.

Bruchide.

Genus BRUCHUS ( Lixy.).
Antenne filiform, slightly and gradually thickened at the tips : elytra oblong quadrate.

Bavcuvus pisi. ( Plate ii, fig. 3.)

Insect small and hairy, ovoid, gray : head black ; thorax gray or mottled, with a central

posterior whitish spot ; elytra gray or mottled: with smal] inconspicuous dots or spots

posteriorly ; posterior abdomen with two black oval spots, and two just beneath the
ends of the wings ; scales black.

The female peabug deposits its eggs in the tender peapod, when the pea is soft and im-
mature ; and when the larva is hatched, it feeds upon the matter with which it is sur-
stianded, until it has attained its full growth, when it bores a gallery to the surface » merely
leaving the surface skin untouched, ready to be pushed off by the head of the perfect
insect when ready to make its exit in April. An infinity of the young grubs are destroyed
in preparing green peas for the table ; but whether the epicure finds any difference in the
taste of pure and infected vegetables, we are not informed.

Seed peas more than a year old do not retain the living insects, and should therefore be
preferred in planting new districts : if these cannot be had, the seed may be immersed
in sealding water for a short time ; a process which does not appear to destroy the ger-
minating power of leguminous vegetables, if carefully performed. This is proved by the
fact that seeds of the locust tree will grow in a single season, if boiling water be poured
over them and allowed to stand until it has become cold.

GENUS CALANDRA. 101

a Genus CALANDRA.

‘Antenne geniculated and nine-jointed, inserted near the base of the rostrum : the elub
is biarticulate ; rostrum elongate, rounded, slightly deflexed and bent ; thorax elon-
gate, narrowed in front, depressed, the base and apex truncate ; elytra shorter than
the abdomen ; body subdepressed ; legs rather short; tibia armed with an acute
spur ; tarsi reflexed, the penultimate joint slightly bilobed’ (Srrpnens).

CALANDRA GRANARIA ( Clairy.). ( Plate ii, fig. 1.)
Color pale ferruginous : head finely punctate ; thorax strongly punctate; elytra deeply
striate and punctate ; legs ferruginous.

This insect is an European species, but has been introduced here in samples of wheat
received from France. Many bottles of sample wheat were entirely destroyed, although
perfectly closed so that nothing could get in from without. It is called the Corn weevil.

I suppose this introduction of this insect, which was accompanied with another, the
Silvanus surinamensis, is only a single instance of its occurrence in this way. When it was
observed that the specimen grain was destroyed by these imported insects, Mr. J. E. Gayit
volunteered to describe and illustrate the insects for publication in the Transactions of the
Agricultural Society of this State. I am permitted to republish this valuable account,
furnished by the gentleman referred to ; as too much publicity cannot be given to a matter
so interesting to the wheat-growers of this country.

Mr. Gayit, in his communication to the Secretary of the Society, states, that ‘in the
specimens of wheat furnished me, I find two beetles : one the true corn weevil of Europe,
Calandra granaria (Ciairvite) ; the other, Silvanus surinamensis, the weevil most com-
monly found infesting the granaries of this State.

‘ The former of these received the name of Curculio granarius from Linnzxvus, but is now
called Calandra granaria. It is somewhat depressed, and varies in color from a deep pitch
to a chesnut tint. The head is semi-globose, produced anteriorly into a longish smooth
cylindrical snout, which is shortest and stoutest in the males : it is slightly curved, and
sparingly punctured with two lines extending almost from the base of the head to the
apex, forming two deep channels before the eyes, where the rostrum is dilated. Eyes black,
vertical, ovate, finely granulated and depressed. The antenne are nine-jointed : the basal
joint being long, stout and clavate, it forms an angle with the remainder; the terminal
ones forming an oyal, conical, little shining club, pubescent at the tip. Thorax twice as
broad as the head, oval, a little truneated : the surface is coarsely punctured with oval
points. Seutellum minute and oval. Wing-covers exactly equal to the thorax and head,
being ovate-truncate, and not covering the apex of the abdomen : there are nine deep
punctured channels down each, producing short pale bristles ; and the two raised furrows
on each side of the suture have a line of long punctures. The six legs are punctured,

strong and stout, especially the anterior and posterior pairs. The thighs are stout : they
all have a hook or claw at their extremities, The tarsi are reflexed and four-jointed, spongy
beneath, basal joint subelavate, second ovate, third broader and slightly bilobed, fourth
clavate and furnished with two minute claws. Length nearly two lines. |

‘This insect seems early to have attracted the attention of naturalists. Leowxxnorx
closely observed its economy, and his observations were published as far back as 1687 ;
but to Ocivien, however, are we indebted for the most accurate and full aceount of its
habits published in the Encyclopédie Méthodique. All subsequent writers appear to have
based their deseriptions on his observations. No insect is more formidable to man than this
little pest, since it attacks the principal basis of his food ; and they are sometimes so nu-
merous in a heap of grain, that they destroy it altogether, leaving nothing but the chaff.
After the sexes have paired, the female makes a hole in the grain of wheat with her ro-
strum, and deposits an egg. These holes are not perpendiculer to the surface of the grains,
but oblique, or even parallel, and are stopped with a species of gluten of the same color
as the corn, Orrvier says there is but one to each grain : I, however, have repeatedly
found two, one in each lobe, and these larvie as plump and well conditioned as those who
had the good fortune of a kernel] to themselves. From the egg is hatched in due time a
small footless grub (fig. 6), which, during its growth, eats out the entire contents of the -
grain, and, when lodged in the grain, is perfeetly sheltered from all injuries from the air,
because its excrements serve to close the aperture ; so there is no use in stirring the grain,
as nothing can incommode it. It is very white; has the form of an elongated soft worm,
and the body is composed of nine prominent rounded rings : it is nearly a line in length,
with a yellow rounded head provided with organs (fig. ¢) proper for gnawing the grain.
When the larva has eaten all the flour, and is arrived at its full growth, it remains in the
envelope of the grain, where it is metamorphosed into a nymph (fig. a), of a clear white,
and transparent : the proboscis and antenne can readily be distinguished ; but it gives no
sign of life, except when disturbed, and then but a slight movement of the abdomen.
Eight or ten days after, the perfect insect eats its way out. In general, that which serves
as nutriment to insects in their larva state is unsuited to the perfect form. To this the
calandra is an exception ; for scarcely has it issued from its nymph state, than it proceeds
to pierce the envelope of the grain, to establish itself anew therein. I have frequently
watched the perfect insect feeding upon the farina of the grain, having pierced the skin
and buried the proboscis to the base. It is often found, however, lodged in the interior of
the grain (fig. e); and its black color does not announce its recent issuing from its state of
nymph, since it is of a straw color at the time when it has just left its sheath : neverthe-
less we must doubtless believe that it occasibns much less injury in this state, than in that
of the larva.

‘The Calandra has no sooner issued from its envelope of nymph, than, like the majority
of inseets, it is in a state of pairing for the reproduction of its species, and this act ever

bears strict relation to a certain degree of heat : if it be under 50° Fahr., it is insufficient
to afford them force or vigor to desire copulation : if the weather be cold, they remain in
a lethargic state, and are incapable of injury ; if warm, they pair very frequently. The
deposition of eggs commences sooner or later, according to the season or climate : the
female deposits them in all months, when the temperature is up to a suitable degree,
ceasing to lay when the mornings grow cold.

‘From the moment of pairing to the appearing of the perfect calandra, there is an in-
terval of forty or forty-five days. By this we may see that a year must produce many
generations, which multiply still more in very hot climates. According to a table for the
calculation of their increase, it results that the sum total of each generation added to-
gether is 6045, proceeding from a single pair during five months, from the end of April
until the middle of September, while the mercury continues above 65° Fahr. We are
therefore no longer astonished if enormous heaps of grain are destroyed by these insects.
The injured kernels may be known by a very simple process : if several handfuls of the
grain be thrown into water, those will swim upon the surface which have been robbed of
their farinaceous substance by the destroyer.

‘Tt is not upon the surface of corn heaps, but some inches beneath, that we find these
insects ; and there, unless dislodged by shaking with a shovel or sieve, they will remain
so long as the weather continues warm, living, pairing, and depositing their eggs. When
the mornings begin to freshen, all, both young and old, retire to clefts of walls and the
flaws of wood and floors. They are sometimes found behind tapestry, chimnies, in fine
every place affording a warm retreat.

‘Tt has been supposed seriously that these insects remain lethargic during the whole
winter, and return in spring to their abandoned grain-heaps, recommencing the deposition
of their eggs ; the cold incapacitating them for the exercise of the functions necessary for
the multiplication and preservation of their species. Based upon the knowledge of this
fact, is the substitution of cold as a remedy. It has therefore been proposed to have a
ventilator, the effect of which would be to keep in a granary a degree of air sufficiently
cold to reduce these insects to the above lethargic state. A general and constant rule among
insects is, that those which have paired perish shortly after, and do not pass the winter
except in the egg or larva state. It is doubtless rare that even those which have not been
exhausted by fulfilling the intentions of nature, can survive the winter rigors. Mr. Gay-
Lorp, however, in his prize essay published in the Society’s Transactions for the year 1843,
says, of some specimens of wheat that he had received from the Patent Office, in which he
found weevils, that “selecting some pure flint wheat kernels, all perfectly sound, we
enclosed a dozen of these weevils with the wheat in a large phial to prevent their escape.
The phial was wrapped in paper, and placed where it would not be disturbed except for
examination. Opening it occasionally for more than a year and a half, I found my weevils,
with the exception of one or two, all living, and appearing to enjoy themselves much on

104 ORDER COLEOPTERA.

the wheat, a large portion of the kernels of which they had hollowed out.” This would
imply that they survive two seasons at least,and those ] have in my possession sustain this
assumption.

‘Many and various modes of exterminating this foe to man have been tried. We first
hear of fumigations with herbs of strong and disagreeable odor ; but this seems useless, as
it does not incommode the insect, while the grain receives a fetid and disgusting scent.
The fumes of sulphur are pronounced equally inefficient, All these fumigations are still
less adapted to the destruction of the larvae, as the smoke cannot penetrate among the
grain, and their perfectly closed envelope seeures them from all such annoyance. Ouivien
recommends the following, as one of the most effectual and least expensive modes of
destroying them. At the return of spring, when the calandre are observed to spread in
the heaps of winter-stored grain, it will be necessary to form small heaps of five and six
measures, and place them at a suitable distance from the large heap : this stir with a
shovel. The insects, who are singularly fond of tranquility, seek to eseape, and, seeing
another heap of grain alongside, they take refuge therein. When all are thus collected,
boiling water is brought and poured over them, stirring it from time to time with the shovel
to secure its penetration through the grain while hot. All these insects then die, being
burned or suffocated at the moment. The grain is then spread for the purpose of drying,
and afterwards sifted to separate the dead insects.

‘It is necessary to perform this operation early in the spring before the deposition of
eggs, the generation existing being only dangerous in giving birth to its successors. This
method may be performed on a large seale as well as a small one, without oceasioning any
considerable expense.

‘ Other experiments have proved that a sudden heat of 75° Fahr. is sufficient to destroy
these insects, without burning them ; and a simple efficacious method is mentioned in the
Tennessee Agriculturist, quoted by Mr. Gaytorp in his essay. “If a hogshead, with one
head removed, be inverted over a fire until thoroughly heated, and then immediately filled
with wheat and reheaded, all weevils in the grain will be killed, and the grain may be
kept in safety till wanted for use.”

‘A gentleman in Madeira has established a heated room, with hot water pipes, in which
he receives as many as eight hundred bags of grain at a time : these become heated through
at about 135° Fahr.; and the wheat, when resifted, is perfectly cleaned, making quite as
good bread as before, the seed also losing nothing of its vitality by this process.*

‘The French “ lay upon the grain, fleeces of wool which have not been scoured : the
oily matter attracts the insects among the wool, when they soon die, from what cause is
not exactly known.”’+

GENUS CALANDRA. 105

‘One essential point in all storehouses for grain is, undoubtedly, frequent whitewashing
and thorough ventilation, as there appears to be much testimony corroborative of this great
preventive to the ravages of this minute destroyer.

‘A correspondent of the London Mark-lane Express, in speaking of the corn weevil
says : “Some years ago, we found a house overrun with weevils : after numberless at-
tempts to destroy them, we were led to observe that they were almost entirely on the south
wall (our rainy side), and that they appeared to breed in incredible numbers in an uh-
usually damp spot or corner. Taking the hint, we cased the wall on the outside with slate,
and made the house in every respect perfectly dry, and in a short time the weevils died
off and disappeared. Since adopting this precaution, we have not the least trouble, and
have only been reminded that such an insect exists when an accidental spot of damp has
appeared to generate them again. We think ourselves, therefore, entitled to say, that these
insects require moisture ; and that if the grain and granary, as both ought always to be,
are dry and healthy, weevils will not long remain. This plan bears the merit of costing
less than nothing, because the injury that wheat sustains directly from damp is more than
equivalent to the expense of keeping premises dry, leaving its indirect influence in the
generation of weevils out of the question.” ’

SILVANUS SURINAMENSIS. “(Plate ii, fig. 3.)

The following is Mr. Gavir’s account of this insect :

‘The insect accompanying the Calandra, and usually found in granaries in this country,
is named Silvanus surinamensis, the corn silvanus. This insect was named by Lixyzus,
being sent to him from Surinam by one of his pupils. Fapricivs, from its infesting stores
and warehouses, called it Anobium frumentarium, and subsequently Dermestes sexdentatum,
from the spines on the side of the thorax. Linnaus’s name, however, has the right of
priority.

“8. surinamensis is only one line and a quarter long, and very narrow : it is flat, of a
rusty brown color, thickly and coarsely punctured, and sparingly clothed with short de-
pressed yellow hairs. The head is large and subtrigonate : the nose appears truncated,
but it is semicireular in front, and conceals the mouth, which is composed of an upper
and under lip, and two little horny jaws, maxille and palpi. The antenne stout, straight
and pubescent, nearly as long as the head and thorax, and eleven-jointed ; the basal joint
stoutish, the terminal ones forming an elongated club (fig. /). The eyes are black, smal],
and coarsely granulated. The thorax is perfectly oval, and a little wider than the head at
the middle. There are three ridges down the back, forming two broad channels, and on
each margin are six teeth. Seutellum minute ; the wing-covers long, elliptical, and broader
than the thorax, with four slightly elevated lines down each : between them are double
rows of punctures, and a series of little shining yellow bristles : beneath are two ample

[ AcricutturaL Report — Vot. v.] 14

wings. Legs short ; thighs stout ; shanks clavate ; tarsi five-jointed, three first joints short,
fourth exceedingly minute, fifth clavate and terminated by two small claws.

‘The larva (fig. g) is a little depressed yellowish white worm : it is composed of 8
tolerably large head, with two pointed jaws and two little horns, and of twelve transverse
segments ; the tail is somewhat conical, and it has six conical articulated legs.

‘The pupa (fig. A) is of the same color; the head is bent down; the thorax is sub-
orbicular, with three ridges ; the elytra wrapped over the sides, and striated : abdomen
with distinct segments.

‘Mr. Cvarts, from whom the above description is derived, says that “ this insect appears
to be naturalized in England and Scotland, lying under the bark of trees*.” I have found
it in sugar, and in boxes containing dried figs in great numbers. It appears to be spread
all over the habitable globe, probably carried in vessels with grain and dried fruits.

‘This is the insect, as I am informed by that excellent entomologist, Dr. Frren, that
infested the mill of Mr. Ricu of Shoreham (Vermont), mentioned in the Cultivator of
December 1846, on which Mr. R. tried various experiments of fumigation, but found
nothing so satisfactory as hot water, whitewashing, and general cleanliness. A correspon-
dent of the same journal, in noticing Mr. Ricn’s experiments, speaks of 2 remedy he never
found to fail : placing sassafras root among the grain infested by them. He is evidently
dealing with the rice weevil, Calandra oryz@ (Liyxaws), an insect exceedingly like the
grain weevil in habits and appearances.’

Attelabide.

Brenthides,

Genes BRENTHUS ( Fan.).

Thorax ovoid ; body rounded or subcylindrical ; antenne inserted at the base of the snout,
just before the eyes. In the males the mandibles are strong and prominent : the fe-
male is provided with a gently curved snout, terminated with a much smaller pair.
Thorax and head as Jong as the body or abdominal portion.

Brentnvs septentrionts ( Hb.). ( Plate ii, fig. 4.)

Males with distinct mandibles : females provided with an elongated snout. Color brown,

polished. Head small; eyes prominent ; elytra ridged and punctured in lines, and

marked with yellowish patches of lighter brown. Length seven-tenths of an inch.
The whole insect is highly polished. A few years ago, I found great numbers of them
apon a recently felled black oak in Canandaigua.

** I have since met with them in the same situation.’

Oblong-ovate, squamose : tibia rounded ; rostrum short; two and three joints of the
antenne elongate.

PuyLiopius T&N1ATUs ( Say).
Gray or hoary, acute behind, widest near the extremity : elytra punctured, with four
darker lines, and darker upon the top of the thorax.

Gexus HYLOBIUS (Ger.), Curcuxto ( Lin.).

Oblong-ovate, winged : rostrum much longer than the head ; second antennal joint elon-
gate.

Hyronivs. pares ( Hb.). ( Plate ii, fig. 6.)

Brown, covered with close-pressed hairs ; hairs gray, in imperfect oblique bands across

the elytra ; punctures of the elytra parallel ; antenne angulated ; rostrum furnished
with an antennal groove.

Gexvus PISSODES ( Gram.).
Antenne situated a little in advance of the middle of the rostrum.

Pissopks staont.
Brown, with two hoary patches on the posterior extremity of the elytra and upon the
middle of the thighs ; somewhat hoary beneath.

The Ruyxcornona, as they are termed, constitute a very extensive group of coleopterous
insects ; some of which, as already seen, have acquired the popular name of weevi/. Many
species are destructive to grain and the seeds of leguminous plants. The larva of the large
Sphenophorus palmarum of the tropics lives in the trunk of palm trees ; and the palmetto
(Chamerops palmetto) of our Southern States is inhabited by am allied species, the Spheno-

zimmermanni of Scueyuenn, which is the largest member of the family known to
inhabit the United States.

Hylobius pales is a common member of a genus which destroys pine trees, by burrowing
beneath and loosening the bark. In April and May, it may be seen in considerable num-
bers upon wooden fences : it is brown, marked irregularly with small whitish spots.
Towards the south, this species and Hylobius picivorus, which is larger and more robust,
destroy pine forests entirely, leaving the dead standing or fallen trees as monuments of
the mischief which a small insect can commit when sufficiently multiplied.

The female of Pissodes nemorensis of German, according to Dr. Hannis, pierces the
leading shoot of the white pine for the purpose of depositing its eggs ; and although a pine
tree may recover by sending up a lateral branch in the vertical direction, it will require
three or four years to pass through this process, and the growth in consequence be retarded.
This insect is named Pissodes strobi by Dr. Harris, on the strength of a name given to it
by a Mr. Peck in an agricultural journal ; which of course can have no weight, because
such publications are unknown or inaccessible to naturalists who are not farmers, and
seldom circulate beyond the boundaries of the district in which they are printed. It is too
much to expect an entomologist in London, Calcutta, Berlin, Paris, or the city of New-
York, to purchase an extensive series of expensive volumes to enable him to find descrip-
tions of half a dozen insects said to be contained in them, and which should have been
made known through some other channel.

Genus BALANINUS (Geam.). Cuncuso ( Lin.).

‘Rostrum nearly as long as the body, which is subtriangular : anterior tibie minutely
‘hooked ; antenne inserted behind the rostrum’ ( Stermens).

FAMILY CURCULIONIDE. ’ 109

Bavanrinus rectus (Say). ( Plate ii, fig. 5.)
Color brown, mottled with lighter patches upon the thorax and elytra. Snout longer
somewhat than the body, and curved at the extremity, slender, elbowed : antenne
inserted below the middle, very slender. Rather less than } inch in length.
This nut weevil inhabits the chinquapin nut, and renders useless almost the whole crop :
the nuts, after being kept a week, are always wormy. It may be the nascicus of Say, but
seems to be smaller.

Ruyncuanus (Conorracnetus) NENupHAR. Plum Weevil. ( Plate ii, fig. 7.)

Color brown, usually dark and somewhat variegated, and variable in individuals, rough

and warty : thorax uneven; elytra interceptedly ridged, arranged transversely in

three rows, the most prominent in the middle ; abdomen thick, deep but short ; thighs
toothed.

It appears from the numerous accounts that have been published, that the mature insect
may appear as early as the last of March, and continue until the first of August ; remain-
ing, therefore, for a longer period than most of the injurious beetles.

The habits of this species are peculiar and interesting. It deposits its ova in most fruits,
as the plum, cherry, apple, quince, and even in the fruit of the hickory. It is also sus-
pected of inserting its eggs into the tender limbs of plum and cherry trees : it is not
known, however, whether those black exerescences are caused in this way, although it is
not improbable. I have found some three or four different grubs in these excrescences,
some of which belonged to a dipterous insect.

The plum weevil inserts in each fruit a single egg, having in the first place bitten a spot
upon its surface ; and although there may be scores of the insect upon the tree, it is very
rare to find more than one wound upon a plum or cherry. The grub produced from the
egg is small, and destitute of feet; and when mature, it falls to the ground and imme-
diately buries itself in the soil : the next spring it appears in the perfect form at the usual
time, when the different kinds of stone fruit are setting.

Among the remedies which have been proposed for diminishing the numbers of the
plum weevil, there is none so promising as the practice of shaking them from the tree early
in the morning and late in the evening, collecting them upon sheets, and committing them
to the fire : the fallen fruit should also be subjected to the same treatment. When the tree
is suddenly jarred, the insect folds up its legs, falls to the ground, and simulates death. It
is easily captured, especially in the morning and evening, when it is stiff, and indisposed
to take flight or attempt to escape. Strong-scented odors seem also to be disagreeable to
this insect, as it is rarely found upon trees situated near the hogpen.

For a full history of this insect and the remedies proposed against 1t, see Harnis’s
Massachusetts Report on injurious insects, pp. 65 - 70.

Conceitio xovenonacensts (Forster) ;
Rayxcarrks corcetionmpes (Herbst) ;
Pacayauyxencs scnaxnnan (Kirby).

According to Krapy, this species belongs to the Family Pacnynuyscmpm + its eharae-
ters, as given by this distinguished entomologist, are :

‘Labrum subemarginate; mandibles armed with two teeth at the apex ; Jabium nearly
square ; palpi conical ; antennse short, inserted into a roundish lateral cavity near
the apex of the rostrum ; joints eleven, scape short, ete. Body oblong pear-shaped.
Rostrum nearly as wide as the head, subeylindrical, a little wider at the tip, ridged
between the eyes and antenna ; eyes round, prominent; prothorax subeylindrical,
rather narrowest anteriorly ; antepectus not emarginate, nor lobed. Coleoptera oblong,
depressed at the apex : thighs clubbed, unarmed ; tibie unarmed ; penultimate joint
of the tarsi bipartite. Its antenna are straight, or only curved, not elbowed.

‘Color gray, covered with a whitish pile; ground black : knob of the antenne brown.
Rostrum rather thick, widened anteriorly, having three ridges between the eyes and
termination : two divergent, from an impressed angular line between the eyes ; and
the other proceeding directly from that line upon its middle, and which terminates
anteriorly in @ short fork, or near the emargination of the labrum, though it is sepa-
rated from this fork by a slight interception, which is just beyond two hyphen-like
lines by its sides. Anterior part of the rostrum naked, and impressed with ccalescent
dots. Eyes brown. Thorax subeylindrical, marked with three rather obscure whitish
longitudinal bands : punctures coarse and coalescent. Elytra have nine rows of
punctures, and at the base a part of a tenth row. The alternate spaces between the
dotted lines have small black quadrate spots : on the sutural space, or ridge, they
are smaller and more obscure than upon the others. These quadrate black spots are
placed upon the four whitish longitudinal stripes, which are quite obscure. Beneath
gray : legs gray. Length of the female, five-cighths of an inch; of the male, half
an inch.’ ,

This Corecorro has the habit of many of the species of this family. It devours the tender
leaves and blossoms of fruit trees, and has been known to do great injury to the apple
and pear. It sometimes attacks the base of a young shoot, and eats it to the pith : at other
times, it feeds upon the leaves of the cherry and plum. Its strong notched mandible fits it
admirably for work of this kind.

The only way to rid a tree infested with this insect, is to shake it suddenly in the
morning or evening while the insects are stiff and cold, and collect them upon sheets sprend
beneath : the insects, and the fruit that fall, should be put into boiling water.

FAMILY CURCULIONIDA. lil

This species has a wide range : it is found in Canada, Northern New-York, Wisconsin,
and Massachusetts.

The following remarks of Prof. Havpeman are highly appropriate in this place :

‘Among rhyncophorous coleoptera, the Genus BaLasinus is remarkable for having a
very long slender snout, frequently exceeding the body in length, and bearing a pair of
antenne as slender as a hair. Chesnuts are frequently found infested with a fleshy grub,
which feeds upon the interior, and fills the cavity with its castings in the shape of dust.
This is the larva of Balaninus nascicus (Say). It is densely clothed with short hair mottled
with ferruginous. An allied but smaller species is found in the larva state in the nut of
the Castanea pumila, or chinquapin. These larve are very difficult to raise to the perfect
state when the attempt is made, and it is probable that many perish from various con-
tingencies.

‘Conotrachelus nenuphar (Herrst), subsequently named Rhynchanus argula by Fasnicivs,
is very destructive to the fruit of the plum, which the Jarve inhabit, and cause to fal]
prematurely. This damage is so great in some sections, that not a single plum can be
raised to maturity. When the fruit falls, the grubs penetrate into the ground ; so that to
check their increase, it is advisable to collect and destroy these (as by boiling and feeding
them to hogs), including such upon the trees as present a dwarfed, imperfeet, or gummy
appearance. Paving the ground around the trees is said to answer an excellent purpose,
and it is well known that plum trees flourish well when planted in pavements. This is a
small rough insect of a brown color, irregularly marked with white, black and yellow ;
and the snout is held upon or near the breast. It is said by Dr. Harris to have been raised
from the black warty excrescences found upon the smaller branches of plum and cherry
trees. The Rev. D. Ziecier of York (Pennsylvania) has shown me specimens of the butter-
fly which destroys the peach-tree (Egeria evitiosa), raised from these exerescences, which
differ from those taken from about the root of the tree in being considerably smaller : the
two forms have not, however, been rigidly compared.

‘The Genus Siropnitus includes a number of small insects called weevil, which are
destructive to stored grain, as wheat, rice and corn ; and under circumstances favorable to
their increase, great quantities are destroyed or depreciated in value. The use of salt, and
kiln-drying, have been recommended as preventatives. The latter process may be per-
formed in an economical manner by erecting a stove with a vertical pipe fifteen or twenty
feet in height : around this pipe, and about three inches from it on every side, a second
one of wood is to be placed ; and whilst the heat from the fire passes through the inner
one, the grain is to be passed through the cavity between the pipes, and at such a rate as
to prevent it from being injured by too high a temperature. The moisture will be more
effectually driven off if the outer pipe is made with open joints, because otherwise it must
rise through the whole column before it can escape, and much of it will condense and be

carried down the pipe again. The corn weevil is named Sitophilus oryze from having been
_ first discovered in rice, a vegetable which it seems to have accompanied to distant portions

of the globe. Infested grain may be detected by its loss of weight, which renders it easy
to separate and boil or grind as feed upon the farm. Mills and barns sometimes swarm with
these insects ; and in this case multitudes may be collected and destroyed by sweeping
them from the posts, walls and floors.

* Phyllobius teniatus may be taken as an example of a leaf-inhabiting ae eee
insect. Scuaznirenn, the great authority upon these insects, removes it into a new genus of
which it is the only representative. It is found upon the leaves of the Jnona triloba, or
papaw, and is perfectly harmless.’

Scolytide.

Tue Scoryrips® are small obscure insects, inhabiting wood : they have a short rostrum ;
the head is globular, and is concealed in the thorax; the body is oblong or eylindrie :
their colors are dull. Among these destructive wood-eaters is the

Gexus HYLURGUS ( Lart.).
Body cylindrical, obtuse before and behind : head concealed in the thorax ; antenn=
terminated in a clubform mass, consisting of three or four joints : the tibie: are armed
with a tooth.

Hytvrevs tereprans (Oliv.).
Pubescent : head rounded, and sunk in the thorax ; antenn@ short.

Gexvs TOMICUS ( Lat.). Bostaicuvs ( Erichs.).
Funiculus five-jointed ; club four-jointed, tunicate ; labium triangular.
Of this genus, several species have been described by Mr. Say and Dr. Hannis. They
are small brownish beetles, with the elytra toothed at their apices, appearing as if a piece
was bitten out.

Tomicus EXEsus.

Color dark chestnut brown, and somewhat hairy : thorax ovate, rough before ; elytra
strongly punctured in rows; apices excavated, the edges toothed on the outer side.
Length between one-fourth and one-fifth of an inch.

This small and obscure insect is found under the bark of the pitch pine tree, where it
exeavates numerous zigzag and parallel roads. It greatly injures forests in this way ; cut-
ting off the circulation of the sap, which ultimately causes the bark to become loosened,
when the tree dies.

FAMILY SCOLYTID. 113

Tomicus Pint.

This species differs from the former in having only three or four teeth at the extremity
of the elytra, and in being a smaller insect. Its habits are much the same as those of the
exesus, in living beneath the bark of the white and pitch pine. The grubs of both species
accomplish more injury to forests than the perfect insect. I have taken the last species the
first of September. Autumn, or late in the summer, is the period when the perfect insect
goes abroad.

Miss Morais describes the 7. /iminaris in the Horticulturist, Vol. iv, p. 502. This dis-
tinguished entomologist suggests that this insect may be some way or other connected with
the yellows in the peach tree, as it is found under the bark. Its color is brown : thorax
punctured, and the elytra both punctured and furrowed, and beset with short hairs.
Length one-eighth to one-tenth of an inch.

Scotytus (Tomicus) pyri (Peck). Pear-blight Beetle ( Harris).

‘Color brown : antenne and legs light ferruginous; elytra punctured in rows, very
‘sloping behind ; tibia flattened at the tarsal end, toothed, and terminated with a
‘small hook’ ( Harris).

This insect has been highly injurious to the pear tree in New-England, and especially
in the eastern part of Massachusetts. It was first described by Prof. Peck. The larva first
eats its way inward into the wood, making its entrance just at the root of a bud : it reaches
the pith, and, by its irritation, appears somehow to poison that portion of the limb above
the bud where it first entered. We say poisoned ; because there seems to be something
more sudden and effectual in causing death, than a slight interruption in the circulation :
the limb or twig looks as if it had perished from gangrene.

The remedy proposed is to cut the limb and burn it, destroying the insect before it is
matured. A careful examination of the pear in June, in order to detect the first appearance
of the approach of the insect, is one of the first steps to be taken.

ORDER I. COLEOPTERA ( Continued).

LONGICORNES.

Tue Loxerconyes of Larnente (Evcerata of Westwoop) deserve a special notice, in
consequence of their habits, and the singular prolongation of their antenne, which is one
of the most obvious characters of the group. The antenn# are filiform or setaceous, and
frequently considerably longer than the whole body. The eyes are peculiar, in consequence
of the position of the antenn#, which often appear to have been implanted within them :
the eye is therefore said to be emarginate, though not strictly so; and it has a reniform
shape, when considered independently of the base of the antenna. The body is elongated
and cylindrical. The elytra are broader than the thorax, which they more perfectly encase
by their sudden flexure at the shoulder, than is common in other groups. The head is
short, and driven into the thorax up or nearly to the eyes : their jaws are powerful. The
legs are long, and frequently the longest in front. The thorax is cylindrical, and in some
species the sides are armed with a short pointed tubercle. The three basal joints of the
tarsi are cushioned beneath : the fifth is long and slender ; the fourth, small.

The insects of this group come out from various kinds of wood in their perfect state,
having inhabited it from the first, or from the time of the deposition of the egg : they are
therefore usually found in the vicinity of wood and dock yards, or where timber is stored.
It may well be inferred from these facts that the larva is injurious to the tree it occupies ;
and the more so, as it is known to remain in this state for many years,

The larve are provided with six scaly articulated legs; but they are of little use as
organs for locomotion, by reason of their smal] size : their movements are rather effected
by means of the warts or fleshy tubercles situated along the sides of their bodies. Their
bodies are soft, and of a dirty white color. The head is only moderate in size, flat and wide.

In consequence of the long time the larve are resident in various kinds of wood, there
is, through commercial intercourse, a tendency to distribute in all countries the beetles of
this large group. A piece of wood from South America is brought by a ship and thrown
out upon some island in the West Indies, or is transported to one of our southern ports,
Savannah, Charleston, or even New-York : the insects contained in the wood are liberated

FAMILY PRIONID. 115

in a new and distant land ; and in this way, this or any other country may become stocked
with new species of insects. In the long run, and with the ever extending intercouse be-
tween the different nations of the earth, it is no visionary imagination that the time will
come when these beetles will be found in every country where the climate is not decidedly
unfavorable to their propagation and existence.

This group of beetles is divided into three families : 1, the Prionipm, embracing the
largest of the group, and provided with very prominent jaws and very long bodies ; 2, the
Ceramsycip®, containing beetles of moderate dimensions, ornamented with a variety of
colors ; and, 3, the Leprurip2, containing insects of a yet smaller size, with bodies dilated
before and narrowed behind, and with antenne of a moderate length.

Prionide.
Prionus PENNSYLVANICUs ( Fab.). ( Plate xxxiv, fig. 10.)
CERAMBIX UNICOLOR (Drury) ;
C. BRUNNEUS (Forster) ;
C cyLinpricus (Linn.).

Insect chestnut brown; head dark chestnut brown. Antenne stout, and two-thirds the
length of the insect : elytra lighter than the head, extending beyond the abdomen,
and nearly three times as long as the thorax and head together ; sides parallel ; ab-
domen, thighs, and tibie red chestnut.

The whole animal is some shade of chestnut brown, but the head and thorax are darker
than the elytra.

PRiONUS LATICOLLIS. ( Plate xxvi, fig. 5.)
CERAMBIX LATICOLLIS (Drury) ;
Prionvs BREVICoRNIs (Fab.).
Insect dark chestnut brown ; head and thorax nearly black. Antenne very stout, consisting
of twelve joints : tibia armed internally with two short spines; tarsi beneath yel-
lowish.

The insects of both species are light and dark chestnut brown ; almost black in the
latter species. Their jaws are stout, and project ; and their bodies are longer in proportion
to the anterior parts, the elytra extending a little beyond the abdomen. They belong to the
large tribe of capricorn beetles, and form a family called Prionide, so termed from the
structure of the antenne, which are jointed, and give the general appearance of a saw.
Some of the tropical species are very large.

116 ORDER COLEOPTERA.

Davry gives a long account of the grubs of this family : he states that they, together
with several other wood-eaters, constitute a delicate eating ; and that in the torrid zone,
a man may supply himself with animal food of this description, provided he has a knife
or other cutting tool strong enough to penetrate the decaying trees. >

Cerambycide.

Axtexne slender, tapering and pointed, often elongated ; eyes kidney-shaped, the con-
cavity of which receives the base of the antenn# ; thorax rounded and convex.

SrENocoRUS cINCTUS. ( Plate xxvi, fig. 2.)
Ceramuix BALTEATUS (Degeer) ;
C. cinctus (Drury) ;

Srexocnorvs Gancanicus (Fab.).
Color grayish hazle : surface covered with a short gray nap. Thorax armed in the middle
with a short spine : elytra ornamented with an oblique ochre-yellow bar near the
thorax. Extreme length 1} inch. Antenne of the males more than twice as long as
the body : seutellum is triangular, and yellowish in color; while the elytra are
margined, and tipped with two small spines.
This inhabits the hickory : its larve form galleries in the trunk of the tree, which run
parallel to the grain of the wood.

Ceramarx? ——. ( Plate xxvi, fig. 9.)

Color black. Antenne ten-jointed ; basal joint oval and short, tuberculated, tubercles

minute ; last joint long, slender; second joint nearly equal the last; the remainder

nearly equal in length. Head with a prominence over each eye and a prolongation at

the base of each antenna, making upon the front a deep longitudinal groove. Thorax

appears to be transversely rugose, cylindrical, without tubercles or spines, but rather

thickened behind, differing in that respect from the thorax of a Saperda, and slightly

constricted near the elytra. Elytra thickly punctured, but scarcely confluent. The

lower part of the tibise and tarsi hairy, but confined to the forelegs ; the others being
only slightly hairy, if at all.

This insect would make a very good saperda, were it not for the extreme length of the
antenne and the form and character of the basal joint. I am not entirely satisfied with its
reference to the Genus Ceramorx, still its characters do not materially disagree with those
given by Mr. Westwoov. Length rather more than } of an inch.

subearinate : first and second bands unite so as to enclose a large spot; the others
transverse and undulatory, and wider upon the suture.
Say remarks that the bands are sometimes white.

Cuytvus pictus. C. flexuosus ( Fab.). ( Plate xvi, fig. 9.)

Color black, ornamented profusely with yellow figures and yellow bands somewhat after

the pattern of the speciosus. The head is marked with three transverse yellow stripes.

On the elytra the first and second stripes are nearly straight, the third forms a W, the

fourth is angled, the fifth is broken by a longitudinal elevated line, and the sixth

consists of dots arranged in the form of an arch. Length variable, but about six-
tenths of an inch.

Ciytus UNDATUS. ( Plate viii, fig. 4.)

Head anteriorly hairy ; parts about the front part of the head rufous; base and apex of
the Interrupted band, of yellow hairs : seutellum dark brown. Elytra marked with
yellow upon their margins ; the basal third is marked with an oblique line, succeeded

by two yellow wavy bands : posterior angles of the elytra rounded off so as to show

the last segment of the abdomen, Beneath, upon the breast, are three yellow spots,

and also at the top of the ventral segments of the abdomen. Length about eight lines.

Ciytus camresruis ( Oliv.).

This is a small species, from four- to six-tenths of an inch long. Its color is brown,
marked with two waved bands across the elytra and tips. The pronotum has four yellow
dots arranged in a square, and the under parts are marked with the same color.

The larva is injurious to fallen chestnut timber, damaging it for rails ; they burrow
between the bark and wood, and also penetrate into the wood. The perfect insect appears
in May and June. It inhabits the Northern States, New-York and New-England, and ex-
tends as far south as Carolina ( Hatveman, Am. Phil, Transactions, x, 40).

CLYTUS HAMATUS. ( Plate viii, fig. 7.)
Color brown ; head banded with yellow ; scutel yellow. Elytra marked with two bars
and a dash; a yellow dash near the base, two curved lines opening towards the
shoulders, the inner leg extending along the suture to the scutel, and a yellow trans-
verse curve opening downwards and situated below the middle : legs brown. Length

half an inch.

Color brown. Head much concealed in the thorax, rather dilated, immaculate. Elytra

marked with three transverse curved bars at equal distances ; outer angle of the apex
pointed : legs long, brown. Length nearly half an inch.

Ciytvs? ( Plate viii, fig. 3.)

Antenne shorter than the body, setaceous ; second joint the longest : thorax globose, un-

presence of a yellowish nap. Head black, impressed with a sutural line with a trans-

verse prominence or ridge at its base. Thorax marked with black oculate spots on the

top and centre ; sides grayish, with a rectangular spot : below it is black. Elytra

clothed with a short nap, marked by about three narrow grayish zigzag lines, and

dashes of the same about the shoulders : towards the apex they are slightly separated ;

and upon the apex, running up the suture, there is an obseure oblong gray spot. Be-
neath, black and glossy : legs black.

FAMILY CERAMBYCID. 119

This species I found in many parts of this State in June, and supposed it common. Al-
though very peculiarly marked, I have been unable to satisfy myself as yet what name it
has received.

Ciytus (Plate viii, fig. 1.)
Color rufescent, covered with prostrate hair : head black ; thorax grayish, from the lighter
colored hair : elytra purplish brown, with three bands of lighter, the basal obscure,

the apicial ones confluent on the elytral suture. All the thighs dilated and robust.
This Clytus is obscurely marked ; and though it may be described, it differs much from
those in my possession, and from accessible descriptions. The bands spoken of are brought
out more distinctly in the figure than they appear in the specimens : the same remark
will apply to the round black spot upon the base of the elytra; and, besides, I may add
that the side of the trunk is marked by a distinct luteous spot, and another smaller one

at the base of the middle legs.

Genus SAPERDA ( Fas.).

Head vertical, as broad as the thorax, slightly compressed at the sides or cylindrical,
destitute of lateral spines : antennz filiform, and terminating in an elongated joint.

The Genus Sarerpa contains several species known to be injurious to the interests of
husbandry. Most of them are rather sluggish in their mature state, manifest far less
activity than many other insects, and rarely attempt to escape when in danger of being
captured. Some of them frequent flowers, but I belive all deposit their eggs upon trees or
shrubs. When the eggs are hatched, the young larve penetrate the bark and wood, and
injure very materially the growth of the tree in which they reside ; and as they are ge-
nerally two or more years in coming to maturity, their hurtful effects are proportionally
augmented. The larve feed upon the wood as they penetrate it, and derive their nutriment
from the juices it contains. Their excrement appears like sawdust ; retaining in fact the
color of the wood, after it has sufficed to nourish them, and has passed through their
bodies. Their form is that which is common to the tribe, the rings near the head being
wider than those of the rest of the animal. The head is usually scaly, and is retractile in
part within the first ring : it is supplied necessarily with strong jaws, in order that the
insect may eat its way into the wood. Their food is constantly before them in their path ;
and it is a very curious fact, that though they may make their way into the wood, yet
they usually direct their course towards the outside when about to change from the larva
to the imago state. The larve are without legs, soft, white or yellowish white, elongated,
and more or less flattened.

One of the most destructive of these species is the larva of the Saperda candida. This

species, liké many other insects, seems to be much more abundant some years or periods
than others, and also more common in some districts than others, In illustration of this
fact, I may refer to the existence of this species in the neighborhood of Troy in 1825.
This was first made known to the public by the late Judge Buex, in one of the numbers
of the Albany Cultivator. He says that ‘he was sent for by Mr. Heart of Troy, to
witness the devastation made in a fine young orchard by a grub hitherto unknown to the
farmers of the vicinity,and which to know and guard against was a great public interest.’
It appears from the letter that the orchard was injured to the extent of two thousand
dollars, according to the estimate of Mr. Heanrtr.

The larva of this species penetrates the young tree just above, or it may be just below,
the surface. In its progress, it euts its way in a winding direction upward ; and as it is
three years in coming to maturity, it continues to mine onward, cuts off the cireulation of
the sap, and deprives the tree of its necessary nutriment. One borer is sufficient to stop
the greavth of a young appletree ; and if several are mining at the same time, the tree is
inevitably destroyed. All the workings being near the root, the tree is after a while so
perfectly riddled with holes that it has no strength to stand. The circumstances that favor
these results, are, first,a poor soil, containing but little nutriment ; the second is the growth
of sprouts or suckers from the root, and of grass, which protects the base of the tree from-
sunshine, and conceals from the view of the owner the work which is going on. Hence all
young trees should be kept free from these incumbrances at the root : this is one of the
preventives of a fatal result, and should not be neglected.

It is needless to dwell upon the injurious effects of the appletree borer. I would take the
liberty to caution the owners of orchards of fruit trees not to trust to uncertain measures,
as the surrounding of the roots and base of the tree with tanbark or any other material —
of the kind. A judicious use of the knife and a good stiff wire are the only certain means
of getting rid of these customers, when they have once got possession of the premises.

The perfect insect, according to Dr. Hanrnis, comes forthgin June : this, at any rate, is
the month during which I have found them. They come out at night : in the daytime they
are engaged in feeding upon the leaves of the tree, or remain quietly at rest, very rarely
flying during the day.

That carelessness and inattention to young and old orchards is the great cause of the
prevalence of this insect among us, is true ; and so long as so many neglect the means for
ridding their trees of this pest, so long it will continue to harass those who are on the
watch, and who intend and wish to raise good fruit. A remedy, consisting of a solution of
eamphor in chloroform, may be tried, by inserting in the borings a plug of cotton wool
soaked in it ; it is worthy of trial, and may save cutting away the sound wood of the tree.
Or perhaps camphor alone, or ammonia formed by rubbing together sal ammoniac and an
alkali, either lime or potash, reduced to powder, and introduced into a burrow where it is
dangerous to follow the larva, may be worth the experiment.

FAMILY CPRAMBYCID. 121

The larvee of the Saperda calcarata infest lombardy poplars. They are yellowish white,
and, when full grown or mature, are nearly two inches long : the body is thick, dilated
before, and consists of twelve segments separated from each other by deep transverse
furrows. In August and September, the beetle may be found on the different species of
poplar : it flies by night. It is harmless in comparison to the appletree saperda ; but one
of our finest shade trees is the aspen, which is often destroyed by this borer. Their pre-
sence may be known by their castings, which lodge on some part of the tree.

The Saperda (Oberea) tripunctata seems to be equally destructive with the two former
to forest and shade trees. It is about the size of the candida, but quite different in its
markings, as will be seen by a reference to the description. It attacks the linden, and, by
burrowing beneath the bark, destroys the vitality of the tree, large flakes of which fall off
gradually and drop to the ground as their attachments are broken.

SAPERDA VESTITA. ( Plate xxvi, fig. 4.)
Color olive or light drab, nearly uniform : surface beneath the close-pressed nap, black.
Head and thorax immaculate. Elytra dotted, each dot giving origin to a smal]l pencil
of black hairs : dot-punctures in lines at the base and along the sides, and marked
with four black dots a little above the middle of the elytra ; and sometimes there are
other dots, owing to the denuded nap upon little elevated points of the elytra. Length
seven-tenths of an inch.

This species attacks the linden : the larve, by their burrows beneath the bark and

_ within the wood, effectually destroy the tree in a few years.

Sarerpa canpipa (Fab.). S. bivittata ( Say). ( Plate xvi, fig. 3.)

Color light brown, marked upy the upper side with two white stripes extending the whole

length of the insect : face, antenne, underside of the body and legs white. The white

is due to the clothing, which consists of a white close-pressed short nap : where rub-

bed off, the surface is black. The white stripes decussate from the forehead, leaving

the grey-brown stripe on the top of the thorax passing down the sutural line. Length
‘six-'to seven-tenths of an inch.

Saperpa (AN=REA) CALCARATA. ( Plate xvi, fig. 1.)
Color gray or ashen, and covered with a short dense close nap : surface covered with
raised points or dots : thorax marked with three pale ochreous stripes, which de-
cussate from the forehead. The elytra are also marked by partial stripes and bands of
the same color : apex terminating ina straight short spine ; beneath pale gray ochre-
ous. Beneath the nap, the surface is black. Length nine-tenths of an inch.
[ Acricutturat Rerort— Vot. v.] 16

SAPERDA TRIDENTA. (Plate xxvi, fig. 6.)
Antenne slender, sborter than the body, second longest. Color rusty brown, approaching
to an olive ; sutural Ine passing through the head and thorax. Inseet ornamented
with pale brick-red stripes : face margined, and eyes surrounded with the colored
stripe referred to. Stripes nearly unite between the antennw ; from thence they
diverge abruptly, and form lateral stripes upon the thorax ; thence they proceed to
the prominent or angular shoulders, run down upon the sides of the ,and meet
the outer angle of the apex, and then pass round on the inside a short istance upon
the sutural line. These stripes send off three diverging ones : the first is arched ; the
seeond or middle is straight, but passes obliquely downwards near the suture ; the
last, or apical one is short, and arched. The sides of the thorax are marked by four
oval spots. The two spots on the top of the thorax are obscure ; but in some
there seem to be four, though the two near the head may be produced by loss 0
drab-colored nap. Beneath hoary, the whitish nap covering a black ground. Extremity
of the abdomen truncate. Outer angle of the elytra rounded.

Sarexnpa ——. ¢

Color yellowish drab, uniform : head, thorax and elytra covered with a close-pressed

short nap. Thorax longitudinally marked with pale yellow stripes alternating with

deeper. Elytra punctured, and marked with about seven obscure yellowish spots on
each.

Sarrupa (Ournea) Taipunctata. Raspberry Saperda. ( Plate xvi, fig. 7.)
‘Color black : breast and top of the thorax rusty yellow. There are usually two elevated «
black dots on the middle of the thorax, and a third on the hinder edge. Antenne of
a moderate length, and scarcely taper. Wing-covers coarsely punctured : punctures
in rows on the top, but irregular on the sides and tips. Length from three-tenths to
half an inch’ (Haanis). There is also a black spot on the sides of the thorax.

Dr. Hannis observes that this insect completes its transformations near the end of July,
and jays its eggs early in August on the stems of the blackberry or raspberry. The grubs
burrow into the pith of the stem, and destroy it by the end of summer.

The grubs are cylindrical in the middle, and thickened at each end. The first three rings
are short, and each is provided beneath with imperfect legs in the form of minute pointed
warts : the rest of the rings are smooth.

MonocHAMUS TITILLATOR. ( Plate xvi, fig. 5.)

Brownish, mottled with gray spots. Elytra tufted with patches of dark brown hairs : an-
tenn, in the male, twice as long as the body ; in the female, they equal it in length.
Length one inch and more.

The middle leg has a protuberance on the upper side. The mottlings are somewhat
variable, owing in part to the removal of the short close nap that covers the insect.
MonocuamMus MACULOSUS.

Color blackish brown. Elytra mottled and furnished with small patches of raised spots
tufted with hair, rather coarsely punctured : apex, on the inner side, armed with a
spine ; outer angle rounded : protuberance of the tibiz one-third the length from the
tarsi. It is rather smaller than the ¢iti/lator.

The two foregoing species are rather common in Albany county : indeed, common to

New-York and New-England.

Monocuamus SCUTELLATUS.
Color dark brown, darker upon the base of the elytra. Scutel white, hairy, strongly pune-
tured : punctures confluent at the base. Antenne and legs dark brown.

Ash-gray, banded : head inclining to brown : thorax ash, together with the middle of the

elytra; base and terminal extremity darker, and somewhat mottled. Length six-
tenths of an inch. Pm,

Dr. Havpeman remarks", that ‘this insect appears in Pennsylvania during the last two
weeks in August and first week in September. It feeds upon the bark of the walnut (Carya
alba). The ova are a Jime and a half Jong, and are deposited in excavations in the small
limbs. After the ova are deposited, the female gnaws a groove around the limb, which
consequently dies ina short time : this seems to be intended for the future progeny, as
the lary are found feeding upon the dead wood. When the insect is abundant, much
damage may be done to the young growth of the hickory, when it is of the size suitable
for hoop-poles.’ When the main stem is girdled by the insect, a lateral shoot appears, that
may be attacked the next year, to be in its turn amputated after undergoing the same
operation : in a few years, the tree presents a curious appearance.

men, apparently of this species, from a larva taken from the dead trunk of a small spruce
tree. The insect is half an inch or more in length, and may be distinguished by its chesnut
color, varied with yellowish spots of down ; the small spine upon some of the joints of the
antenne, and two upon the tip of each elytron; and by the smooth raised medial line,
and tubercle, upon each side of the pronotum above.

FAMILY LEPTURIDA. 125

When the larva attains its full growth in the branch, which is about half an inch thick,
it cuts it off transversely from the inside, leaving the bark alone untouched ; and this
_ slender hold is severed by the storms of autumn, when the branch and larva fall together.
The larva does not leave its shelter until the next spring, when it appears as a perfect
insect in May and June.

PHYTOPHAGA.

Tuts division (Europa of Larnemie) embraces a group of insects whose bodies are short,
oval, thick, and hemispherical (for an example, see P]. xiv, 11). The thorax is sometimes
angular, uniting closely with the base of the elytra, and forming with them a circle or a
broad oval. The head is short,and concealed ; the antenne shorter than the body, filiform.
The insects are usually small, but their colors are lively and brilliant, though only a few
are metallic in this climate : the Eumolpus is one of the brightest. They are vegetable
feeders in the larva and perfect states, and some of them are highly injurious ; the Haltica
destroying the turnip crop, and the Crioceris the asparagus plant.

Crioceride.

Tue body is oblong in this family, and the hindlegs are often thickened for leaping. The
head and thorax are narrower than the abdomen. The antenne are filiform, or only slightly
thickened at the tips : they are inserted before the eyes, which are prominent. Found
upon leaves and stems of trees.

Crioceris ( or Lema ) trilincata ( Oliv.), is a yellow insect about one-fourth of an inch
long ; the elytra with three black lines, one along the middle of the back, and one on
each side. It belongs to an extensive division which contains many species that are de-
structive to garden vegetation, generally devouring the leaves, both in the larva and the
perfect state. The species here cited attacks the foliage of the potato, and Dr. Harris
recommends brushing them into shallow vessels of salt and water, or vinegar.

CRIOCERIS DUODECIMPUNCTATA.

Color yellow : thorax and head brownish; beneath, yellow. Elytra punctate in many
rows, and marked with six black spots : each side of the thorax has also a black
stripe. Tibial extremity of the femur black, as well as the tarsi. Length rather less
than a quarter of an inch.

green spots which converge to each other, the outer the largest : parallel with the
marginal line there are three large spots ; the remainder are scattered and smaller.
The dots are distributed somewhat irregularly, but there is a tendency to arrangement
in rows, as at the base of the elytra and along the lines and larger spots.

The insect from which the description is drawn is rather common, but it does not agree
with the description of the philadelphica by Kirsy, who makes no allusion to the markings
upon the thorax. The differences I regard as sexual.

In a few plates, I observe that the gronnd color is too green ; it should be pale, or
cream-color.

CHRYSOMELA DECIPIENS.

Head, thorax, body and seutel dark green : elytra silvery white or white. Sutural line
thickened, and divergent near the seutel : the parallel and proximate lines wide,
divergent before, and narrowed towards the apex ; the second is shorter, and united
to it; and the third is similar to two heavy dashes united at their points, but instead
of being straight, they form a curve divergent from the other lines : these lines are
dotted. The shoulders are marked by a heavy dash or oblong spot : two other spots
are situated between the shoulder spot and marginal line ; the upper roundish, and
the lower oblong. There are thirteen spots on each elytrum, besides those already
described, each of which is enclosed by a row of dots. Antenne, palpi and legs rufous.

This species differs from the preceding, in having the thorax entirely of a dark green,
and also in the distribution and form of the lines and markings upon the elytra.

CHRYSOMELA SCALARIS. ( Plate xiv, fig. 10.)
Head, thorax, body and seutel dark green : elytra silvery white. Sutural line green, and
extending to the base : a coalescing line falls into it just below the seutel, and forms
with it an unequal stripe. There are two oblique dashes, which do not meet, on each
elytrum. The spot upon the shoulder is double, and prolonged in the form of a curve,
and there is another curved spot between the shoulder spots and sutural line. There
are three coalescing spots upon the posterior flexure of the elytra. The other spots are
arranged somewhat in two lines, parallel with the outer margin of the elytra ; and
there is a solitary dot near the middle, and upon the outer margin of the elytra. The
dots are so arranged that they follow the boundaries of the spots. Antenne, palpi and

legs rust-brown.
In the specimen figured, a brownish color predominated instead of the silvery white :
it may be a distinet species from the scalaris, and is found in the autumn upon verious

plants.

brown. Autumn, and feeds upon the Solidego.

CunysomeLa ——. ( Plate xiv, fig. 2.)

Head, body and thorax reddish brown; eyes black : elytra yellowish brown, and striped

with reddish brown or ferruginons. The punctured lines are also reddish, of which

there are about ten to each elytrum, running parallel to the margins. Length one-
fourth of an inch.

I am unable to determine whether it is a de —_— or not.

FAMILY GALERUCID. 133

CHRYSOMELA TREMULA. ( Plate xiv, figs. 5, 6 & 7: larva and pupa.)
Head, thorax, body, antenne and legs blue : elytra brown, finely punctured.
Foreign : its larvae feed upon the leaves of the poplar.

CHRYSOMELA BANKSII.

Immaculate, obtusely ovate : head very small; antenne luteous ; thorax with the lateral
edges thickened. Color dark brown, glossy, impunctate. Elytra of the same color as
the thorax, punctated : beneath, the same color as above; soles of the tarsi cream-
colored. Length nearly one-fourth of an inch.

CuRYSOMELA AMERICANA.
Form ovate. Color brown, glossy : eyes black ; thorax and head impunctate. Elytra pune-
tate in four double rows, besides the sutural one : between the rows the surface is

flat, impunctured, and of a brassy bronze reflection ; the punctured lines are purplish.
Length one-eighth of an inch.

Galerucidae.

Tuts family is exemplified by those very common striped beetles which infest and destroy
the cucumber plant. They are oblong,and are furnished with a small head and a narrow
thorax. Their antenne are about half as long as their bodies, of a uniform thickness, and
inserted near together and near the mouth. Their legs are of an equal size, though in some
the thighs are formed for leaping. They are small insects and vegetable feeders, and often
do considerable damage in gardens.

The family is divided by Westwoop into two subfamilies : 1. Garerucipes; 2. Han-
TICIDES.

Galerucides,

Genus ADIMONTA ( Scurank).

Antenne eleven-jointed, filiform throughout, and nearly equaling the body in length :
joints mostly cylindric ; the last acute,and pointed outwards ; the second the shortest,
obeonic ; the third next in length, the two equaling the first or fourth ; the remainder
equaling the first or fourth : labrum entire : palpi indeterminate. Head small, exsert :
eyes prominent : body ovate, elongate : legs rather long, equal or subequal ; yoste-
rior thighs only moderately incrassate.

134 ORDER COLROPTERA.

Apimoxsta ——. ( Plate xiv, fig. 4.)

Color yellowish green : head and its appendages black. A depression and two eminences

behind the antennw. The three first antennm yellowish green; on the outer side,

brown; the remainder dark brown or black : pectus black : abdomen yellowish

green. Thorax greenish yellow predominating, immaculate ; two slight indentations

on each side, with a slight lateral ridge or dilatation. Elytra pale green, nuarked with

eleven black rather quadrangular spots ; most of them have their angles rounded, so

as to approach an oval form; the basal spot is common to both elytra, Legs black :
upper half of the thighs greenish. Length one-fourth of an inch.

It will be evident from the above generic and specific descriptions, that this insect is
neither a Galeruca, Lema or Haltica, and probably not an Jdimonia : it belongs, however,
to the vast family Gateavcros. It is rather common in September and October on the
asters and solidagos, Either the descriptions within my reach are faulty, or else it has not
been deseribed.

LEMA TRIVITTATA.

Rufous : thorax and head rufous; the former punctured transversely at its base, and
marked with two black dots. Elytra marked with longitudinal black stripes, the
middle sutural : punctures arranged in lines. Antenne black ; first joint rufous :
lower tibia and tarsi black. One variety more rufous,and marked with wider stripes
and larger dots upon the thorax : sometimes the dots are absent.

Resembles the striped cucumber-bug.

GALERUCA VITTATA.

Color yellow : head black. Elytra marked with three black longitudinal stripes, including
the sutural one : abdomen black ; forelegs mostly of that color : knees and feet o
the other legs black.

This insect is troublesome to various vines, and especially to young cucumber vines
when not of a vigorous growth. The best remedy is to seeure a strong and rapid growth :
other remedies, which are more or less successful, are, washing the plant with offensive
liquors, or sprinkling them with strong-seented powders. Tobacco in its various forms,
whale-oi! soap, ete. are all more or less useful.

Gaveruca catmanrensis ( Lin.). ( Plate xii, fig. 12.)

This is a European insect, which has been introduced into this country about Baltimore.

It is destructive to the foliage of the elm. It is about one-fourth of an inch long, and is

deseribed by Mr. Stevens as follows : ‘Oblong-ovate ; above testaceous, deeply punc-

tured : crown, furrow on the thorax, sentelium, a dash on the elytra, Lrenst ond Tare of
abdomen, black ; apex of the abdomen and base ef ie antenme testaceous.

FAMILY GALERUCID&. 135

(EpionycHUs THORACICA.
Color of the elytra blue purplish, immaculate : thorax luteous, marked with eight black
dots ; outer margin luteous. The outer half of the tarsal joints and antenn Juteous ;
the rest purplish. .

Halticides,

Genus HALTICA.
‘Form oblong-ovate : thorax narrower than the elytra; posterior tarsi short’ (West-
woop).

This genus coiwprises many species, all of which are small, and whose posterior legs are
formed for leaping. They feed upon the leaves of vegetables, more especially upon the
cruciform plants, as mustard, radish and turnip ; the latter of which often suffers exceed-
ingly, in consequence of the insects eating the young and succulent leaves, perforating
them like a sieve. Their colors are often brilliant.

Haurica CHALYBEA.

Body oblong oval : thorax marked with a transverse furrow. Color steel-blue, but variable
and passing into greenish blue : underside green ; antenne and feet black. Length
from one-sixth to one-fifth of an inch.

Davip Tuomas, of Cayuga county, has given in Silliman’s Journal an account of this
species of Haxrica. This excellent observer noticed that his vine leaves were infested with
a small smooth chestnut-colored larva; and on feeding them in a tumbler partly filled
with earth, they came to maturity and buried themselves, and in two weeks afterwards
came out the perfect insect, after having undergone their transformation. The larva feeds
upon the tender fruit buds while in a growing state, and hence destroys the fruit for the
season. The use of a solution of whale-oil soap would undoubtedly, protect the vine, and
drive away the insects.

The cucumber is infested with another species of Hatrica, which has received the name
of H. cucumeris from Dr. Harris. It is black, one-sixteenth of an inch long, with clay
yellow antenne and legs, except the hindmost, which is brown : the thorax is marked by
a deep transverse furrow ( Harris).

Another is the wavy striped beetle, Haltica striolata, and feeds upon the horse-radish,
mustard and turnip; in which respect it resembles the European species, which feeds
upon and destroys the turnip crop.

CHAPTER Xi.

ORDER I. COLEOPTERA (Continued ).

PSEUDOTRIMERA.

Tis division of coleopterous insects constitutes the Tamms of Lavavioe. Taking the
number of joints in the tarsi, the division would be represented by insects supplied with
only three tarsal joints : on close inspection, however, it is found that there is a small
joint in the lobes of the second. The form of the insect is oval, sometimes hemispherical :
the elytra cover the abdomen. They often feed upon the .pAis, and thus perform a useful
service to gardeners and farmers. Their colors are often bright,and their thorax and elytra —
marked in various places by dots and spots (See Plate xi, all the figures; and letters ¢,
6, ¢, d, larva and pupa state of the Coccinella).

Coccinellide.

CocctxeLLA poreacis ( Lin.). ( Plate xi, fig 8.)
Color luteous ; eyes black. Thorax marked with four black dots, the largest behind upon
the central line, and pointed backwards. Elytra marked with seven black dots each, the
largest situated towards the apex, and two upon the sutural line. Beneath Jutecus ; breast
black.

CoccINELLA INCARNATA. ( Plate xi, fig. 7.)

Flesh-colored above. Thorax marked with two large transverse black spots; elytra with

seven black spots each, or eleven as they appear when closed, three being common to
each ( Rien. Faun. Bor.).

COCCINELLA QUINQUEMACULATA. ( Plate xi, fig. 5.)

Body black : thorax black; anterior angles white : elytra tawny; base banded, and

marked with four black spots, the middle spots quadrangular. Length about three
lines.

FAMILY COCCINELLID. 137

CoccrnELLA 20-macuLaTa. ( Plate xi, fig. 4.) .
Color pale honey-yellow, marked with twenty black spots somewhat confluent on the
middle of the elytra. Insect quite small.
In some of the plates the green coloring is too deep. There is a variable state of the
ground color : sometimes it is entirely pale honey-yellow ; in other instances, there is a
grayish green tinge.

CoccINELLA NOVEMNOTATA, : ( Plate xi, fig. 6.)

Color luteous and reddish, marked with nine black Spots ; one common to each elytrum,
situated near the base. Thorax black, margined in front with pale honey-yellow : the
black portion extends in front towards the head : body black. The color of the elytra

is somewhat variable, yellow and reddish predominating each in different individuals.

CocciNELLA IMMACULATA. ( Plate xi, fig. 9.)
Color luteous : thorax black, margined with pale honey-yellow or whitish : elytra im-
maculate : body black. The flank of the thorax is quadridentate.
This insect does not agree with Mr. Say’s description in every particular, still it is not
so different as to preclude the idea that it is a variety.

CoccINELLA PIMACULATA. ( Plate xi, figs. 10, 11.)

Color ferruginous, verging into luteous. Thorax varied with black and white ; the white

dilated margins being marked with a black dot, the black arranged in the form of

two decussating wide lines. Head marked with a central black line, which divaricates

posteriorly, or sends off branches to the eyes. Elytra marked usually with a single
black dot : body black beneath. ‘

CoccINELLA TRIOCULATA.
The black spot upon the elytra is larger than in the preceding species, and the dilated
white margins of the thorax are immaculate : the color of the insect is paler. The abdo-
men is black, bordered with rufous.

CoccInELLA DUODECIMNOTATA,
Body black : head black and quadridentate in front, margined with luteous : thorax
black, marked with two oblique rectangular spots, and margined with luteous. Spots
of the elytra twelve, and none of them sutural.

CHAPTER XII.

ORDER Il. EUPLEXOPTERA ( Westwoop).

Tuts order of insects (the Dermarrera of Leacn) is extremely small as to numbers, but
the individual species are widely distributed. It bears a relationship to the orders CoLro-
preraA and Orrnoprera, having by different naturalists been placed in each : it is, how-
ever, regarded as having a closer affinity with the latter than with the former, in conse-
quence of the peculiar structure and foldings of the wings. In the structure of the mouth,
and the transformation of the insect, it corresponds to the orthopter, but to the coleoptera
in the folding of the wings. The order is characterized thus by Westwoop :

‘Anterior wings leathery, very small and uniting ina straight suture, horizontal, partially
covering the wings. Posterior wings large with radiating nerves, and with numerous
transverse and longitudina] folds. Mouth with transversely movable jaws, the poste-
rior pair being galeated. Anus forcipated. Pupa semicomplete, active, resembling the
imago, but with rudimental wings.’

The type of this order of insects is the common carwig, an insect far more notorious in
other countries than in this. It will be readily recognized by its elongated form, its short
wings like the Staphylinus, and the forked armature of its abdomen, which forms an organ
of offence as well as defence. Its habits are somewhat peculiar : it is nocturnal, and goes
abroad for its food by night ; but with the appearance of light, it seeks to hide itself in
holes and crevices where it can escape observation. Tradition affirms that it creeps into
the ear, but it does not appear that there any facts to sustain the assertion.

The Forficula is a vegetable feeder, subsisting upon flowers, fruits, ete., and is regarded
as an injurious insect. Hence the English gardeners take advantage of its propensities,
by placing in proximity to the flowers and vegetables they wish to protect, crab’s claws,
or narrow reeds closed at one end, into which the insect takes shelter, where it is readily
captured and destroyed.

CHAPTER XIII.

ORDER IL ORTHOPTERA (Ottvier).

Tus order (the Heamrresa of Linsavus) embraces those insects whose wings, when at
rest, are folded longitudinally upon the body, and present a straight outline : for this
reason they have received the designation orthop(era, which literally means straight-winged.
In this name, then, we perceive one of the distinguishing characteristics of the order. In
4 dition, however, to this single character, we find their wings folded like a fan : they

“ve also a pair corresponding to the elytra in beetles, which are of a leathery consistence,
aud perform the same office, that of protecting the delicate wing beneath. Their wings
and wing-covers are deflected upon the sides of the body, forming an angle with the top, -
and, besides these peculiarities, they overlap each other upon the back. By this arrange-
ment, the males are furnished with organs wherewith to produce different sounds, while
a particular modification of the organ enables each species to form its peculiar note.

Orthopterous insects are provided with jaws which move transversely, similar to beetles,
and hence the name mandibulata applies to them.

Another and still more important characteristic is found in the kind of metamorphosis
they undergo. In this respect, they differ greatly from beetles and the butterflies ; their
metamorphoses or transformations are incomplete ; their young, in the early stages of life,
resemble the parents in miniature, their wings being the most imperfect parts ; they eat
and move about like the adult, and, like the young in other classes, they grow until they
reach the perfect state. From these comparisons, we see why they should be separated from
the beetles, and placed by themselves in an order expressive of the characteristics that
belong to them.

The order has been divided into four sections, formed from differences of habit due to
the peculiar construction of the organs of locomotion. The sections have received their
names from the modes in which these organs are used : the first embraces the xunwens,
Orthoptera cursorta ; the second, the Grasrens, Orthoptera raptoria ; the third, the
watkens, Orthoptera ambulatoria ; and the fourth, the sumpens, Orthoptera saltatoria.

In the section comprising the runners, we find the cockroaches ; in that of the graspers,
the mantis, whose forelegs are used as arms and hands; in that of the walkers, the
walkingsticks ; and in the section of jumpers, the grasshoppers and locusts.

FAMILY BLATTID. 141

The arrangement seems to be clear and satisfactory, and yet it will be seen, as in most
other arrangements, that the lines of demarkation are imperfectly drawn ; for in the section
containing the cockroaches and earwigs, the insect possesses the power of flight : still it
is probably suflicient for all practical purposes.

Some of the species of orthopterous insects are extremely prolific : thus cockroaches
become innumerable, and locusts appear in clouds that darken the sky ; and, even in our
own more favored country, who has not seen the red-legged grasshopper multiply to such
an extent as to devour all the herbage of hundreds of ,acres!

Blattide.

Tuts family (Cursoria, the runners) is represented by the well-known and troublesome
cockroach. The body is oval, flattened : wings coriaceous, with their inner margins over-
lapping each other. The thorax is large, often concealing the head : antenne long, simple
and setaceous, being formed of from fifty to one hundred and fifty joints; mandibles
short, strong, and toothed at the tip ; upper lip entire ; labium bifid ; eyes kidney-shaped ;
legs long, formed for running ; tarsi five-jointed ; abdomen furnished with two articulated
processes. The males are smaller than the females.

We have several species of cockroach, which either inhabit fields or woody places. The
common domestic one (Blatta orientalis) is an imported kind, and is very troublesome in
basements, cellars, etc.; while the former, or indigenous species, never comes into our
dwellings.

The methods that have been proposed for destroying the domestic cockroach are nume-
rous : they consist in the use of substances which are generally poisonous, and therefore
should be used with due precaution. Arsenic, red lead, or other mineral poisons may be
mixed with mashed potatoes or meal, and set upon the shelves, floors, ete. frequented by
the insects ; and as they are fond of almost every kind of vegetable mixture, they greedily
devour the mess, and are speedily poisoned.

These insects penetrate the most hidden parts of a building, even into the brick work
of walls, where their young are frequently produced. They sometimes disappear from the
premises without any known cause : at other times, their numbers greatly diminish in a
short period of time.

BLATTA NIVEA. ( Plate xlvi, fig. 7.)

‘Head and antenne yellow ; thorax and abdomen pale green; wings and wing-covers

white and transparent; legs and underside of the abdomen pale ye green’
(Drury, Vol. ii, p. 39, f. 1).

142 ORDER ORTHOPTERA.

; Mantide.

Tus family, which succeeds the cunsones or runners in the natural arrangement, consists
of insects technically called nartones or graspers. The largerand more remarkable species,
of which the Mantis is one, are not found in New-York or New-England, but smaller kinds
are occasionally met with. Plate vii, fig. 4, exhibits the structure of an insect similar to the
mantis, which takes its prey by grasping or seizing it with its forelegs. Its habits, too, are
much like those of the mantis : it remains motionless upon a twig or limb of a bush, in a
sitting posture with its front parts elevated, until a desirable object comes within its reach.
The family are all carnivorous, and hence aid in diminishing the number of vegetable
feeders.

Phasmide.

Tue insects of this family (.2mbulatoria, the walkers) are distinguished by the undeveloped
state of the wings, or by their total absence. One or two of these remarkable animals are
found in New-England and New-York : they are commonly called walkingsticks, and the
most common species is the

Spectrum remonatum (Say). ( Plate vii, figs. 1, 2.)
Apterous : intermediate thighs dilated, and furnished with a spine near the tip ; posterior
also spinous.

The color of the male is greenish with a mixture of brown, especially on the forelegs”
and the tibia and tarsi of the others : abdomen equalling the body, and furnished with
nine segments, terminated with two curved appendages. Female brownish, thick, with the
trunk and abdomen nearly twice their size in the male : legs greenish, but less so than in
the male ; the thighs less dilated.

This species is rather common, in the months of August and September, in the vicinity
of Albany and in Western Massachusetts.

Saltatores,

Tmus section (Saltatoria, the jumpers) is represented by the common cricket, and embraces
those insects whose tarsi are three-jointed, antenn setaceous, head large, with a convex
crown, and inserted deeply into the thorax ; with ovate eyes, and two or three ocelli. The
thorax is truncated in front ; elytra horizontal ; body elongate ; wings folded longitudinal-
ly ; abdomen cylindric ; legs stout and short; tarsi without foot-cushions between the
claws.

FAMILY ACHETIDA. 143

Achetidae. 4

ACHETA ABBREVIATA.
Color black : elytra turgid, brownish posteriorly ; abdominal appendages elongated and
pilose ; posterior tarsi armed with a double row of spines.

Crickets are nocturnal in their habits, and hence seek their food and their mates in the
evening. If numerous, they become injurious in gardens ; feeding upon the different kinds
of fruit, melons, tomatoes, potatoes, beets, ete. : when in fields, they eat the tender grass.
They are not, however, confined to a vegetable diet, but they kill and devour such insects
as they can overpower. The insect lays its eggs in autumn : they hatch in the spring, and
the young are three years in coming to maturity.

To diminish the number of crickets in gardens, arsenic may be resorted to.

The mole cricket, Grillotalpa brevipennis, differs from the common cricket in the dilated
form of the tibia, the lower side of which is strongly notched to fit them for burrowing.
These notches have a distant resemblance to fingers, and they give to the organ the power
of a hand. From the construction of the forelegs, then, and the use to which they are
applied, the species has received the name of mole cricket. They are fawn-colored, and
covered with short velvety down : they reside in soft moist soil, and throw up ridges of
loose earth ; they feed upon roots, and, if numerous, might do considerable damage : they
are, however, rarely seen, and the effect of their feeding is searcely perceptible. Length
about one-fourth of an inch.

® No one, who takes much notice of the habits of insects, but must have observed the -
extreme timidity of the cricket. This is especially true of the field crickets : when they
issue from their dwellings, it is with extreme caution; and when the slightest approach
of danger is visible, they seek at once their asylum, and do not again appear abroad until
all their suspicions are allayed.

It is well known that the black cricket flies well ; but it has been observed by natura-
lists upon whom we may place confidence, that field crickets never use their wings. This
I believe is mainly true ; but yet frequently when they are pursued, they spread their
wings, and make a more extended leap by their use. Their wings are not defective in
construction, but seem to be well organized and fitted for flying. The males, it is said,
carry on a destructive warfare upon each other during the breeding season.

In some crickets the wings are undeveloped : some species prefer damp and even wet
places ; others, dry and stony.

Crickets have been destroyed in great numbers by placing in their way vials half-filled
with beer, into which they crowd and are drowned.

144 ORDER ORTHOPTERA.

‘ Gryllide.

Tits family (the Grasshoppers) is characterized by the possession of four jointed tarsi, long
setaceous antenn®, a large vertical head and convex forehead, vertical prominent eyes, a
thorax flat above, and its sides suddenly detlexed and rounded behind : body more or less
compressed ; the breast furnished with two oval foliated plates; elytra coriaceous, de-
scending the sides; abdomen compressed slightly, and furnished in the male with two
processes, and in the female with an ovipositor. The legs are long behind, with thickened

thighs and spines.

Piaryrnyitium concavum (Harris). Katydid. ( Plate ix, fig. 1.)

Color of the body pale brown; elytra and wings, grass-green. Antenne long, setaceous,
yellowish, dilated at the base; eyes prominent, hemispherical; head greenish,
brownish on the top, front ridged, terminating between the antenne in a triangular
apex : thorax greenish, rough, its integument saddle-shaped. In males the musical
apparatus occupies a triangular space, covered with a dense parchment-like membrane.
Elytra narrowed before, dilated behind and laterally widest near the extremity of the
abdomen, and longer than the wings : nervures consist of one principal trunk, sending
off numerous branches below at right angles to it. Wings narrower and shorter than
the wing-covers ; branches of the nervures two. Legs green : tibia quadrate ; each
corner serrate or short spinous. Body of the male over one inch long. The
furnished with a curved ovipositor (see the figure) about one fourth of an inch long,
and both sexes with two projections between the forelegs. The wing-covers, in their
natural position, form a convex covering extending in the female far enough to cover
the ovipositor.

The katydid is in its state of perfection in September : the female, about this time,
deposits her eggs in a row upon the twigs of the tree she inhabits. Dr. Hannis describes
the musical instrument as consisting of a pair of taborets : they are formed of the mem-
brane already spoken of, which is situated at the base of the wing-covers. This parchment-
like membrane is stretched upon a strong, half oval frame, fitted into the space at the base
of the thorax. Their notes are emitted during the evening and night, and sometimes in
dark lowering weather in the afterpart of the day. It is not common, neither is it easy to
discover the retreats of this singular insect : the color of their wing-covers favors their
concealment among the foliage of the trees. ,

The katydid feeds upon leaves ; but it would not comport with the truth, to charge it
with doing much damage to the farmer.

FAMILY LOCUSTID. 145

PHYLLOPTERA OBLONGIFOLIA.

This species differs from the preceding in having the wing-covers narrower, flat and not
concave, the true wings extending beyond them, and they are deflected down the sides
abruptly. The most distinctive characteristic is the absence of the projecting integuments
between the forelegs.

PHANEROPTERA ANGUSTIFOLIA ( Harris). ( Plate ix, fig. 1.)
Color brownish green : wings and wing-covers green, the former narrow, their upper and
lower edges being nearly parallel, forming an organ equal in width except at and
towards the base, shorter than the wings and rounded behind. Abdomen terminated
in the male by a short projection, which curves upward. The wings do not conceal
the body. Length of the body, three-fourths of en inch; the whole length, about
the same as the katydid.
The habits of the three foregoing species are much the same, each kind coming to per-
fection in September ; but the sounds they emit are different.

Locustidae.

Tue name Jocust is applied usually in this country to our harvest-fly, which is commonly
called the seventeen-year locust. The term locust, however, is here improperly applied, in-
asmuch as the insects which have been known from time immemorial as locusts belong to
a different order from the harvest-flies. The rule of priority should be regarded in this
instance ; and, besides, the name harvest-fly is sufficiently appropriate. The true locusts,
on the other hand, have been called grasshoppers ; a term which, by better usage, belongs
to the green insects of which the katydid is an example. The true locusts possess the
following characters : their antenne are shorter, and usually filiform ; the elytra longer
than the body, though, in forms removed from the typical, they become abbreviated and
distorted. The ovipositor of females is not exserted.

Genus LOCUSTA.

Antenne filiform, inserted into a slight depression between the eyes : head large; eyes
ovate ; thorax furnished with a central sharp ridge ; elytra longer than the abdomen :
four anterior legs subequal, short ; posterior long, and formed for leaping ; tibia all
furnished with a double row of spines.

LocusTA CAROLINA, ( Plate ix, fig. 9.)
Color brown, variegated with darker spots : wings black, margined with yellow ; apex
spotted with brown or blackish. Length an inch and a half’; breadth, or expansion
of wings, nearly three inches. Common by roadsides.

a triangular yellowish spot, and two or three others on the same line more or less
obsenre, Anterior border of the wings brown and variegated ; the base is vermilion,
and widely bordered with brown or dusky and nebulous; the inner portion of the
border darker than the outer, and the apex is still darker or more dusky.

Appears early in the spring : is rather smaller than the preceding, and more active.

Locusta suLPHuREA.

base of the wings sulphur-yellow, varying in brightness in different individuals ;

margin broadly bordered with dusky, which extends in a sharp patch upon
the three nervures towards the base ; wing translucent, darker at en
yellowish.

This is subequal to the corallina, appears rather later in the season, and pncteditdey
places.

Locusta nesviosa ? ( Harris). ( Plate ix, fig. 7.)

Color brown : thorax ridged, or furnished with a keel-like elevation, and divided in the

middle by a transverse fissure ; wings transparent, with a duskiness of the anterior
margin; thighs banded transversely with yellowish and brown ; tibie brown.

This species, though very common in Western Massachusetts, is described in part from
the figure, the original specimen being lost. So far as I ean determine under the circum-
stances, it is the nebu/ose of Hannis,and yet he does not speak of the banded markings of
the thighs : in other respects, it agrees with his deseription of that species.

Grxus ACRYDIUM.

This genus differs from Locusta, in having a spine beneath, between the forelegs : the
ridge upon the top of the thorax is wanting or obsolete; and the antenn# are generally
longer, in consequence of the joints being more elongated, consisting of 24 or 25 joints.

AcaypiuM FEMORRUBRUM. ( Plate ix, fig. 4.)

Color olive-brown above, yellowish green beneath ; antenn pale yellow or olive, darker

at the tips; face green or yellowish green ; thorax marked with two yellowish lines

extending between and along two outer angles, olive-brown upon the top; also an-

other triangular area extending backward from each eye, the base resting upon it.

Wing-covers olive-brown, lighter upon the angles. Lower end of the femur surrounded

by a black belt, and the upper end of the tibia marked in the same way. Yellow

predominates upon the thighs beneath and inside; top brown and reddish brown ;
tibiee and tarsi bright red, terminated by four spines » beneath yellowish

FAMILY LOCUSTID2. 147

AcRYDIUM FLAVOVITTATUM.
This common species is larger than the former, and is marked with a yellowish stripe
on each side from the forehead to the tips of the wing-covers. Length 1} — 2 inches.
Very common in haying time, and often found in barns among the newly gathered hay.

Gexus TETRIX.

This genus differs from Locusta and Acryprvom, by the long and sharp triangular outline
when seen from above, or rather the double triangular form of the body of the insect, the
base or widest part being between the middle legs, from which it tapers each way ; the
head being smaller than in the former genera. The insect is smal], with small wing-covers ;
but the wings are large in proportion to the size of the body, and scollopped on the edge.
The females have four boring appendages, which are notched on their edges.

Dr. Haxnis divides the genus into two groups : first group, antennz 13- or 14-jointed ;
second group, 22-jointed, with additional characters not necessary to be noted here.

For a very full account of these three genera, see Harnis’s Treatise on Insects, 2d ed.

CHAPTER XIV.

ORDER IV. APHANIPTERA ( Kimsy)

SUCTORIA ( Decren). APTERA ( Lamancx).

To avoid incongruities in classification, all that fumily of insects known as fleas, have
been separated from their associates, and made an order under the name above given :
the order therefore consists of the single family of the Poricrox, of which the common
flea, Puler irritans, is the leading type. The body of this insect is covered with a firm
integument, somewhat shining, and more or less covered with bristles arranged in rows.
Its mouth is suctorial, and is composed of a complete apparatus both for inflicting wounds,
and for sucking the blood or juices into the stomach.

The Petictow are all small insects, yet their anatomy is well known, as made out in a
very elaborate manner by Curtis, Westwoop, and M. Ducrs. The mouth is composed of
seven pieces ;: it has two round eyes situated upon the sides of the head, and antenne
placed behind them in a small cavity which is usually closed with a lid or scale. The
thorax has three segments : the abdomen is large ; the wings are represented by small
scales ; the legs are long, but muscular, and hence are capable of performing wonderful
feats in leaping.

The flea appears to have a choice among the animals it selects for its prey : the pig and
dog seem to enjoy a preference ; and for its favorite haunts it selects filthy straw, shavings,
litter of most kinds,and dry sandy spots. In these places, under favorable conditions, fleas
increase enormously ; and the surface of sand where hogs have been littered during the
winter is often black with them, especially in southern countries.

The chigre, or jigger, Pulex penetrans, of the West Indies, belongs to this family : indeed
the species of Purex are quite numerous; thus the dog, bat, hedgehog, mole, mouse, and
cat have each their peculiar species. So even birds are infested with parasites belonging to
this genus.

It is in warm climates that the pests of this family most particularly abound, and their
torments are most felt and dreaded, rendering a residence there extremely uncomfortable.
In our own country, cleanliness is the antidote to fleas. The dooryard is frequently the
nursery for them, especially where chips and decaying wood are allowed to accumulate,
mixed with straw, the refuse of the kitchen, and the blood of domestic animals that have
been killed for food.

An infusion of tobacco is an effectual remedy for domestic animals against fleas, and
the heaps of filth in which they are engendered should be removed and burnt.

CHAPTER XV.

ORDER V. HOMOPTERA.

OMOPTERA (Leacn). HEMIPTERA ( Larrerte).

Tue insects of this order are provided with a suctorial mouth, resembling in this respect
the Heteroptera, but with the mouth placed nearer the sternum. Notwithstanding this
resemblance, the two orders are quite distinct, and the lines of demarkation well defined.
The wings of the Homoptera, in the first place, are entirely membranous, and do not
overlap when at rest; the antenne are short and setiform, and the tarsi number three
joints. The metamorposis is of that kind called semicomplete, and the pupa is therefore
active.
~ In this order are found insects of very remarkable forms : it is true, such a remark is
often made respecting other orders, yet probably no insect shows more grotesqueness of
outline than the leafhopper. Some subdivisions of the order contain insects which singly
are perfectly insignificant ; yet as they increase to an enormous extent during a single
season, they become, from numbers alone, a formidable foe to the interests of the farmer.
The Homorrera are divided into three families : 1. The narvest-rvtes, called in sy-
stematic arrangement Cicadida, or cicadians ; 2. The prant-ice, Aphidide ; and, 3. The
BARK-LICE, Coccide.

Cicadidae.

Antenne short, awl-shaped, and terminated with a bristleform point : eyelets three ;
wings and wing-covers inclined at the sides of the body, transparent and reticulated ;
feet three-jointed ; integument of the body hard and firm. Females furnished with
an ovipositor lodged in a furrow beneath the abdomen. Insects walk and fly.

The harvest-flies are so called from the circumstance that they make their appearance
about the time of harvest. They possess some remarkable characters which have served to
give certain species a great notoriety, particularly the seventeen-year locust, which makes
its visits only at intervals of seventeen years, and then in great numbers : hence its
systematic name, Cicada septendecim.

150 ORDER HOMOPTERA.

CicaDA SEPTENDECIM.

The males are distinguished il pn is ete
production of a rather sharp and rattling sound, which may be heard unto the distance of
a mile. The females are destitute of this apparatus, and may be known from the males by
the ovipositor before alluded to. The musical or sounding organs are situated on the sides
af the insect, just behind the wings. They consist of plaited convex membranes, of a
texture somewhat like thin parchment, and lodged in small cavities in the sides ; these
membranes emit their peculiar sound by means of muscles attached to their insides, which
serve alternately to increase and diminish their tension with a rapidity almost ineoncei-
vable, while other accessory members assist in augmenting the loudness of the tone thus
produced by the vibrating membranes.

The Cicada septendecim is black or dusky ; anterior margin of the wing-covers, and
larger veins or nervures orange red ; eyes, rings of the body, and legs of the same color.
Expansion of wings from 24 - 3} inches. The figure near the tip of the wing-cover re-
sembles the letter W.

The most interesting fact connected with the history of the seventeen-year locust, is the
mode in which the species deposits eggs and makes provision for its future progeny. The
insect, in this climate, issues from the ground about the middle of June. As soon as the
wings of the perfect insect are in a condition for flying, it selects a tree for the scene of its
future operations. The sexes pair, and, soon after, the female prepares to deposit her eggs.
She selects the extremity of a limb for this purpose, and applies the ovipositor, which is
fitted both for perforating the branch, and for sawing it in such a way as to separate and
detach the fibres, which are afterwards made to serve as a surrounding protection to the
eggs. The eggs are deposited along a line in which some ten or fifteen perforations are
made, some of which receive two eggs apiece. Soon after her labor is accomplished, the
insect dies of exhaustion. The limb or twig, which has received its burthen, speedily
perishes, and, being nearly severed from its supporting branch, falls to the ground, bearing
with it the eggs; or, if the twig be not detached, the eggs are hatched in place, and the
young full or precipitate themselves to the ground. Whether hatched above or upon the
ground, they soon penetrate the earth, descending among the deeper roots, where they
attach themselves ; and there they remain, extracting the juices of the roots by means of
the sucker with which they are provided.

Miss Maaearerra H. Morais has the credit of having first observed the fact that the
larve of the cicadide were injurious to fruit trees, by wounding the roots with their
suckers, and drawing therefrom their sustenance. It would seem that in consequence of
these wounds, and the drainage of sap by the numerous individuals thus attached, the
root becomes unhealthy, and incompetent to supply the tree with its requisite amount of
nutriment. Under some circumstances, therefore, where a fruit-tree becomes sickly without
an apparent cause, a search about the roots may disclose the fact observed by Miss Morais ;

FAMILY CICADIDE. 151

but the long-settled districts of the State, those which were reclaimed from the forest fifty
years ago, will not be so much subject to attacks of the kind. Observation at the time of
the appearance of these insects will tend to throw some light upon the question, whether,
for instance, a certain tree was known to have been infested by them.

The Cicada lays between four and five hundred eggs; and hence the provision for the
continuance of the species, it would seem, is ample : in consequence, however, of the
accidents to which it is subjected in its larva and pupa state, its increase is by no means
great, and in the older sections of New-York and New-England it certainly does not hold
its own in numbers.

The larva does not necessarily descend deep into the earth : never beyond the reach of
the roots of the trees on which it feeds; and in some places where I have seen it issue
from the earth, it could not have penetrated directly more than six inches, in consequence
of the underlying rock. It is hardly necessary to repeat the old notion respecting them,
that they continue to descend for eight and a half years, and then begin their return to the
surface ; yet it is well established that they appear only at intervals of seventeen years,
making some allowance for the irregular appearance of a few which may precede or
succeed the main brood a year or two earlier or Jater than the rule allows. For a similar
reason, probably, the cicada does not appear the same year in different parts of the coun-
try".

Mr. Hanuis has given, in his treatise on insects injurious to vegetation, a long list of the
times when and places where the seventeen-year locust has made its visits, together with
an interesting history of the economy and habits of this singular animal. The insect, ac-
cording to the author referred to, does not select any particular species of tree in preference
upon which to deposit its eggs : most, if not all kinds of trees except the pine and fir,
have been found with their limbs pierced by it.

The eggs, according to the observations of Miss Morris, are hatched in forty-two days:
others say in less time ; but however this may be, prior to the time of hatching, most of
the wounded branches which have received eggs are detached, and have fallen to the
ground : at least this was the case when they appeared in the vicinity of Troy about the
year 1830. The twigs perish much sooner when wounded by this insect, than if a wound
of equal magnitude were inflicted upon them with a knife : indeed, in a very few hours
after receiving a deposit of eggs, the twig is perfectly dead.

The extent of injury inflicted by the these locusts upon forest and fruit trees does not
seem to be very serious : it amounts to only a foreshortening of the limbs ; and if the
tree is injured at all, it speedily recovers. The injury is far Jess than that which often
follows when the wound is made in the axis of growth. No remedy seems to be required,

Cicapa camsovtanis. Dogday Horvestfly. ( Plate ix, fig. 3.)
Body black : the head beneath, breast and sides mealy ; top of the head and thorax

ornamented with olive-green lines connected together so as to form characters, one of
which upon the thorax resembles the letter W. Legs, front of the principal veins of
the wing-covers and wings edged with green. The body of this species is thicker and
proportionally shorter than the septendecim : abdomen of the male tapers rapidly.
Appears late in July, and continues into September.

According to the observations of Mr. Haxnis, this species is very regular in the time
of its appearance ; for many years in succession, it has been heard for the first time at
Cambridge on the twenty-fifth day of July, between the hours of ten in the forenoon and
two in the afternoon. It is therefore an annual visitor, in which respect it differs widely
from the preceding species, while its other habits are much the same. It deposits its eggs
in the extremities of the branches of various trees. It is not particularly injurious to fruit
trees, nor indeed to any other species of vegetation ; besides, it never has appeared in
sufficient numbers to excite any apprehension of injury.

CicADA NOVEBORACENSIS. ( Plate ix, fig. 2.)
Body black : veins of wing-covers and wings, thorax and abdominal rings edged or or-
namented with orange.
This species is smaller than either of the preceding ; but it appears annually, and has
the same habits as to the mode of depositing its eggs. It is never in sufficient numbers to
inflict serious injury to forest or fruit trees.

Tree-hoppers, Leaf-hoppers, ete.

Form triangular, but variable in the different genera : eyelets two; musical instruments
none; locomotion by leaps aided by wings.

These grotesque insects inhabit the trunks, limbs and leaves of trees : they are small ;
colors green, gray, with spots or cloudiness of the wings ; faces often vertical or nearly
so, with the thorax and anterior parts thick, whence they taper rapidly to the extreme
points of the wings; legs furnished with spines. The species are very numerous, each tree
and shrub being inhabited by its own peculiar kind.

As this group of insects have habits much the same as the cicadians, and obtain their
nutriment by sucking the juices of plants, it is supposed that in some cases they may be
detrimental to vegetation : they cannot, however, injure the farmer very materially,
though as a class they are quite numerous.

The general reader will be able, from the figures which are given of a few of the genera
and species belonging to this subdivision of the Homoptera (or Hemiptera), to distinguish
them from other insects. It is true they are small in number, or at least less numerous than
the plant-lice, aphide : still their forms and habits, as well as consistence, will always
serve as diagnostic marks. So far as their food is concerned, as well as their mode of
obtaining it, they resemble plant-lice : they wound the plant by puncturing it with their
beaks, and suck the juices. When they are few in number, they do but little mischief : on
the contrary, where they are numerous, the wounds they inflict, and the diversion of sap
they occasion, have quite an injurious effect upon the health and perfection of the plant.
Among the plants most liable to be injured by them, the vine probably suffers the most ;
for it abounds in sap, and hence offers support to large colonies of these insects.

-

168 ORDER HOMOPTERA.

In the eighth volume of the Encyclopedia Americana, Dr. Flannis has described the
leafhopper, Teftigonia vitis, It is about the tenth of an inch long, and arrives at maturity
in the month of August : it is of a pale straw-color, and inhabits both the native and
foreign grape vines, and, in some seasons, is so numerous as to affect seriously the vines
and fruit. They adhere to the underside of the leaves, and hence the remedy proposed,
which consists in fumigation with tobacco, will be more effectual than if they inhabited
the upper side, For the purpose of fumigation, the vine or its trellis should be covered
with a tent, and the process may be persisted in until the insect is thoroughly routed or
destroyed. ood

Rosebushes sometimes become infested with a kind of leafhopper, the Tettigonia rosa,
-which may be treated in the same way.

As the insects of this family hop briskly, they cannot be dislodged from the vines by
shaking, nor is it practicable to catch them : it hence becomes necessary to destroy them
by fumigation, or by the application to the leaves and vines of some substance destructive
to the insects, but which will not injure the plant. Whale-oil soap in solution is another
remedy whose application has been followed with success.

As these insects take refuge among the fallen leaves and underlying grass, where they
survive the winter, the leaves and grass should be carefully removed and burned, either
after the weather has become cold in the autumn, or in the spring before vegetation has
put forth. All these methods should be resorted to, where vines suffer from too great an
abundance of these insects.

Aphididae.

Tae apnrptans ( plant-lice) are a group of insects with soft bodies of an oval form, and
furnished posteriorly with two tufts or pores. The females are generally wingless, though
not always. The upper pair, answering to the wing-covers in the Heauprera proper, are
larger, and are used for the purpose of flight, or to assist in leaping.

The leaping plant-lice belong to the Genus Psyiia : the young are covered with a
cottony substance, and are found upon the alder and some other plants in the spring.

The genus to which the name Arnis has been given, from which the name of the family
is derived, and which signifies to exhaust, is one of the most remarkable in the class of
insects : feeble and entirely unprotected, the insect is crushed by a touch, or swept away
by a breath. It is, however, provided with the means of increase to an immense extent ;
and, hence, in consequence of this extraordinary power, in virtue of its numbers alone it
is competent to infliet the most serious injury upon the plants it inhabits. Most plants are
infested with them ; and each particular kind of plant, shrub and tree, supports its own
peculiar species, though it does not seem to be proved that the juices of many plants may

FAMILY APHIDIDZ. 159

not furnish wholesome nutriment to several different species of insects. Indeed the same
plant may bear two or more kinds of lice, and they may occupy the root, leaf, stem, or
bud.

I have alluded to the greatness of the number of aphides. Considerable attention has
been paid to this part of their natural history. Reaumur has probably investigated the
mode and rate in which they increase, better than any other naturalist : he ascertained
that a single individual may be the progenitor of six thousand millions of individuals
during the life of five generations. The eggs are laid in the autumn upon the buds of the
plant, and are hatched in the spring : this takes place when the leaf is just expanding
and tender, to which the delicate aphis is attached by its sucker, and from which it sucks
the juice. They grow rapidly, and speedily come to maturity. The most remarkable fact
connected with this first brood, which is hatched from the egg, is, that the individuals,
however numerous, are all wingless females, which present this anomaly, that they are
competent, without intercourse with the male, to beget another generation of females, and
this another, and so on to the seventh generation. After these generations have succeeded
each other, another generation, consisting of males and females, is produced in the an-
tumn : pairing takes place, and the eggs are laid upon the buds as has been stated, and
in due time are hatched ; and thus the broods are produced in the successive seasons after
the same fashion. The generations all perish in the autumn, and the subsequent continua-
tion of the race is committed to the egg. The males have wings. ;

A young leaf that curls, or looks unhealthy, is probably infested with aphides : they
will often be found clustered together, engaged in sucking the juices of the leaf; and as
they are voracious feeders, nature has provided them with the means of ejecting their food
in an uncommon way. This is done through the two posterior tubes : the ejected matter
appears first in the form of a pellucid fluid, which is sweet, and has received the name of
honeydew. Ants, being fond of sweet fluids, are in the habit of frequenting plants infested
with aphides, which they treat in a very gentle and tender manner, feeding merely upon
the fluid without inflicting the slightest injury upon the insects that draw it from the
plant. Another insect, however, the /acewing, unceremoniously thrusts its curved beak
into the sides of the aphis, and sucks the insect dry, leaving nothing but an empty skin.
The presence of ants upon a plant indicates also the presence of aphides.

The aphis, as already stated, infests most plants : the rose, the asters, apple, peach,
pear, cabbage, ete. etc. are only a few among many upon which we may find it to an in-
jurious extent. Besides it is not unfrequently the case that they exist beneath the soil and
upon the roots, where they cluster together in vast numbers, and extract the ascending
nutriment : these are usually white.

The peach-tree is known to suffer extremely from the aphis, which, when numerous,
affects it in a way that prevents its bearing fruit. My own trees suffered for three suecces-

160 ORDER HOMOPTERA.

sive seasons from this insect : the young leaves of the first product curled, thickened,
became red or brown, and most of them perished. The trees afterwards put forth a new
crop of leaves, and all survived, though the fruit was destroyed in the blossom. ( For a
delineation of the peachtree aphis, see Plate xxix, fig. 7.)

It le evident. from, the foregoing zemarks, that plant-liee are injarions, bath. thaongh the
wounds they inflict upon the parts of the plant they inhabit, and from the fluids or nu-
triment they abstract from the cireulation. As a family, their habits are the same, but
some species or kinds appear to be more injurious than others ; and it seems difficult to
account for all the effects they produce, unless they possess a poisonous principle. In
support of this observation, I may state that the pear is infested with a kind that kills the
tree when young. Of this fact, I was informed by Dr. Ovin Piums of Salisbury (Connecti-
cut) : the limbs or twigs which he showed me were brown and dry in patches. Afterwards
Mr. Haxais of Cambridge investigated the matter, the results of which he has communi-
cated in his work on inseets injurious to vegetation. Dr. Pius», who was the first to notice
these minute parasites of the pear-tree, entered with much zeal and spirit into the in-
vestigation of their effects, and of the remedies to destroy them.

The genus to which this insect belongs is Psyua, one of the jumping plant-lice, but
destitute of the cotton-like covering. From the observations of Dr. Piums, it appears to
give birth to two or more broods during the year, being found upon the pear from May
to October. They first appeared upon imported trees. My own trees, which were obtained
from Rochester, and were also imported, had many limbs that appeared rusty and dry ;
and though these limbs were lost, the trees survived. The appearances of the limbs were
similar to those of the branches preserved by Dr. Puume; but I was unable to find the
aphis, although I sought for it diligently.

This insect is described as of a dull orange color, and one-tenth of an inch long when
perfect : the thorax is brownish orange. The female is more pointed behind than the male.
According to Mr. Hannis, it may prove to be the Psylla pyri of Europe. It may be well
to remark, that when the branches of a pear-tree become dark and dry in patches, it is
advisable to search for this insect. The remedies recommended are, first, rubbing off the
lice with a brush. Mr. Hanass advises the application of strong soapsuds with sulphur,
by means of a brush, before the buds expand : so also the use of whale-oil soap*.

The insects of the Genus Tuarps, likewise belonging to the Family Armpiz, are also
injurious. Their wings, instead of lying obliquely upon their backs as in the Genus Arms,
lie flat, and are fringed. They are supposed to poison plants by their puncture, producing
thereby curls and a thickening of the tissues of the leaf. They may be treated with soap
and water, or whale-oil soap dissolved in water ; a strong decoction of tansy may serve.

* Hanais on Insects injurious to vegetation, p. 202.

FAMILY APHIDID. 161

A species of Turirs infests the kernel of wheat while in its milk state ; and it is quite
doubtful whether this one can be destroyed by the application of fine slaked lime, as has
been recommended ; still, when the dew is on the plant, a free sprinkling may be tried,
which, if not successful in the way designed, will at least benefit the soil.

The disease called appletree blight is due to another genus of aphides, the Exrosoma.
It is a woolly insect, destitute of wings, but is wafted from tree to tree by the buoyancy of
its woolly envelope. The eggs, only visible under a microscope, are enveloped in a cotton-
like substance found in crotches of the tree and chinks of the bark ; and if there are
suckers standing around the tree, it may be found on them also. The full-grown insect is
one-tenth of an inch long, emits a sticky juice from its extremity, and is covered with
flakes of down : when this is removed, the color of the antenne, head, sucker, and spines
is blackish ; abdomen honey-yellow ( Harris). It feeds upon the sap of the alburnum of
the apple-tree ; and the wounds it inflicts give origin to warts, excrescences, and inequali-
ties upon the bark : the final result of its attack is the death of the tree.

It appears from the accounts which have been published of the ravages of this aphis in
England and in this country, that the only hope of arresting the evil lies in beginning at
once, or as soon as the insect makes its appearance. After it has extended itself far and
wide upon the large trees of an orchard, it becomes exceedingly difficult to arrest its
progress, and this probably only happens in cases when the weather becomes unfavorable
to the life and propagation of the insect. The rational way to go to work, will be to scrape
thoroughly all the trunks and larger limbs, and then to scrub the surface with strong
soapsuds, or whitewash them. When the trunk beneath the soil and the roots are infested,
extend the treatment to these parts also. Mr. Harris recommends a solution of potash,
and to protect all the wounded parts by grafting wax, and also the removal of all refuse
from and about the tree that may contain the eggs or the living animals : cut off, like-
wise, and burn all the smaller limbs. It seems that all strongly scented solutions, such as
tobacco water, ammonia, ete. are more or less effectual remedies against the depredations
of the various kinds of aphides.

Another interesting and important fact in natural history is that plant-lice have nume-
rous foes, that prey upon and destroy them in great numbers : among these foes we may
rank the numerous species of Coccinella, or ladybirds (See Plate xi, where several of the
most common kinds are figured). A person unacquainted with these small and beautiful
insects, on seeing them upon an infected plant, might mistake their characters and office,
and attribute to their presence the sickly state of the plant. He could not well commit a
greater mistake ; and to convince himself of this, he would only need to watch the move-
ments of the little beetle for a short time, when he would find that its errand was one of
kindness to him and his plant, for he would soon observe it feeding upon the plant-lice :
these constitute its food, both in the larva and mature states, so that its services in re-

[ Acricutrurat Rerorr— Vor. v.] 21

moving the plant-lice are by no means inconsiderable. He might, indeed, advantageonsly
stock his house-plants with the coceinel/la, for the purpose of keeping them clear of lice.

I have already adverted to the lacewing ;: in its larva state, it is probably one of the
most sanguinary enemies of plant-lice. Where these abound, the eggsof the lacewing may
he seen each supported on the end of a slender thread.The larva or grub is provided with
a large pair of curved pointed hollow jaws, with which he seizes the aphis, and sucks all
the fluid contents of its body, leaving nothing but a collapsed skin.

Mr. Kiney states the fact, which is also now well known to many, that a fly belonging
to the Genus Syxenvs is equally effective in exterminating the aphis; their larve or
maggots having completely exterminated a colony which had a week before infested his
currant-bushes. :

Coccidae.

Tae sank-tice form a third division of singular insects, from which, judging from the
appearance of a few individuals among them, we should never expect serious injury to
trees or plants. They vary in form ; sometimes they are kidney-shaped seabs, beneath
which, at some period or other, may be found a brood of minute lice : others are oval,
quite large and globular, of a dark gray color, and are fixed to the surface of the bark, or
have lost the power of locomotion ; these are females.

- As an illustration of the character of the Cocctda, I may state that the matter of the
cochineal of commerce, brought to us from Mexico, is an insect of this family. _

These insects are usually known under the name of bark-lice, of which the kind that
inhabits the branches of the appletree is probably the most common. They differ in struc-
ture from the aphides, their feet consisting of a single joint terminating in a claw. The
male is quite small in comparison with the female, and, like that of the aphis, is provided
with wings, which are two in number, and lie flat upon the body as in the Genus Tuauirs.
The female, after she has become fixed to the limb or bark of the tree, having lost the
power of locomotion, brings forth beneath her a brood of young, which, when able to run
about, escape from the dry skin of the parent, and fix themselves by their beaks to the
bark, where they grow and become mature upon the sap of the tree.

A maple at my door in Hudson-street, Albany, is infested with thousands of individuals
of a species of Coccus, about the twentieth of an inch in length, and covered with the
woolly matter peculiar to the family, which imparts to the limbs a snowy appearance. On
the first of September, the back of the leaf supports some twenty individual females of a
green color, beneath which are the young.

Trees suffer from the minute punctures of bark-lice ; the apple-tree particularly, which
is infested with a kind that resembles a dry scale, having the color of the cuticle of the
bark on which it rests. The remedies for these depredators are the same as have been re

¢
FAMILY COCCID. 163

commended against aphides, particularly the brush, soap and water, and scraping the bark
with a suitable instrument. Several sorts of birds, such as wrens, chickadees, creepers, ete.
feed upon the larger coccide.

A large brown coceus, the tenth of an inch in length, inhabiting the chestnut and black-
oak, gives origin to one kind of honeydew. These trees, in Warren county ( New-York),
were teeming with a species of coceus in 1838 ; and from their bodies drops of a sweet
fluid were cast, which, on falling to the ground, were formed into minute threads. These
appeared in sunlight like the threads issuing from the gossamer spider. The leaves and
grass were covered with this substance. The insect had an oval form, about.the size of half
a marrowlat pea, with a brown, wrinkled, naked skin ; that is, it was destitute of a woolly
or cottony covering.

The currant-bush at present suffers from the attacks of an aphis, which has been in-
creasing in numbers for three or four years past. The insect occupies, as usual, the under
surface of the leaves. The female is uniformly green, and provided with antenne longer
than the body, and three rows of bristles along the back : body ovate, thicker behind,
with the honey-tubes near or along the outer row of bristles. It produces a thickening and
reddening of the leaf, and the crisped condition that comes from punctured wounds of the
parenchyma. This valuable plant should receive a timely attention, before the insect has
increased much in numbers ; and as a remedy, whale-oil soap is undoubtedly the best.

The snowball (Viburnum) has been infested for years with a peculiar aphis, which
effectually destroys the beauty of the shrub. In some cases the leaves are all crisped and
rolled, and the consequence is the total loss of the beautiful and ornamental flowers pe-
culiar to this species of Viburnum. The insect makes its appearance with the expansion of
the first leaves, and continues through the season. The usual applications which have been
recommended, should be employed upon this plant.

The black cherry, also, is infested with an aphis in July. The community consists of
males and females. Mares : antenne black and equal to the body in length, pointed
forward ; head and thorax black or greenish black ; abdomen green; wings twice the
length of the body ; thighs and tarsi black. Frmares green; antenne two-thirds the
length of the body, turned over the back or pointed backwards ; tarsi black ; wings ru-
dimentary. This aphis lives upon the uppermost leaves of the young virginian cherrytree,
where the females produce their usual effects, the curling, thickening, reddening, and
finally the death of the leaves.

For fruit trees, it appears to me that the best remedies against insects are those of a
preventative character. Trees that are kept in a thrifty growing condition by the applica-
tion of manures, ard the use of means to keep the bark clean and smooth, rarely suffer
from lice. Among both plants and animals, the feeble are generally those which suffer
from parasites. It is not, I believe, beeause the tree has become weakened in the first place
by them, but, on the contrary, the plant (and so also with the animal) first suffers for the

164 ORDER HOMOPTERA. be

want of proper nutriment, or by other neglect. It is true that @ Vigorous plant or animal
may become infested with parasites ; but these cases are exceptions, and not the rule. We
have therefore every motive to induce ugto protect and nourish our plants and animals,
both for the greater profit they will render us, and as a security against disease and the
attacks of parasitic animals.

:

Amospherie Blight.
Trere is a disease among cultivated herbaceous plants, the origin 6f which is not deter-
mined. The plant, as the june pea, for example, begins to dry and whiten below = this
dryness extends upwards, and sometimes so rapidly that the crop of pease is lost; but
whether this be the case or not, the crop will be greatly diminished, and the early death
of the whole plant is the consequence. The disease may be said to be a premature decay
and death of the plant : it is equivalent to a blight, or to the potato disease. The question
that arises respecting it, is, Is it due to an insect, or to atmospheric causes? The answer
to this question is neither definitely negative nor positive. No inseets have yet been de-
tected upon the pea; and yet its root, which has not perhaps been sufficiently examined,
may disclose some insect that brings on this decay. As to the atmosphere, physiologists
may well differ : we ascribe to changes of the weather, those diseases and injuries that
cannot be referred to the attacks of insects. Remedies have not been proposed ; but it is
suggested that a change of seed may divert the calamity, or perhaps soaking the seeds in
muriate of ammonia or a weak solution of copperas, and then rolling them in plaster,

The /ychnidea becomes sometimes affected with a white mouldiness, which makes its
appearance upon the leaves early in July, and destroys the beauty of the plant, beginning
upon the lowermost part of the leaf, and extending upwards until the whole is coated with
a fibrous matted mucor. It does not appear to be of animal origin : under a single lens, I
have not been able to discover any thing that looks like the work of an insect. The ques-
tion is, Whether this fungus is the consequence of a too feeble vital action ; or, to speak
more cautiously, whether what we call vital actions are enfeebled by any causes other than
those which may be attributed to wounds by insects? The parenchyma of the leaf is not
destroyed, but the surface is covered with a white fibrous fungus, analogous to the coverng
of the gooseberry when affected with mildew.

In undertaking to assign a cause for effects of the foregoing kind, it should not be for-
gotten that a minute puncture may result in the production of a fungous growth : the
juice exuding from a wound, whether poisoned or not, undergoes a change that fits it for
the growth of fungi, which may be in some instances small and invisible, while in others
they extend over large surfaces, and, as in the lychnidea and gooseberry, occupy in time
the whole leaf, or the whole surface of the fruit; so that a puncture, to us invisible, and
which may be made by an insect, can yet be detected in its consequences. The greater

ATMOSPHERIC BLIGHT. 165

effect may be the fungous growth ; the lesser, the exudation of sap from the puncture, so
that in these cases the effect might be mistaken for the cause. The effect of remedies may
aid us materially in arriving at a correct determination of the cause.

There is still another affection of the leaf, which results in the injury if not the death
of the plant. The elm, maple, chestnut, and several other trees are affected in the way
about to be deseribed. Their leaves dry at the apex or on the edge, become brown, and
curl up. This affection may appear upon a small part of the leaf only, or it may cover the
whole surface of a part or all of the leaves upon a branch : if only a few leaves are dis-
eased, the branch will live ; if all, it dies simultaneously with the leaves; and in some
instances the disease affects so many limbs, that the life of the tree is imminently threa-
tened. An elm standing before my door in Hudson-street has lost a part of its branches
every year for many years in succession. Another thrifty elm was extensively affected, and
most of its large branches died in the course of two weeks. The disease is the same in both
eases, and, I think, in all the instances which begin by the drying of the apex or margin
of the leaf, whatever may be the species of the tree. In no case could I find an insect to
which the effects could be attributed, but the affection seems to prevail most under the
influence of certain peculiar states of the weather ; and I have also observed, that when
the potato rot has been prevalent in its worst form, the trees have been most severely
affected with this disease.

This disease constitutes a form of blight, which, on a close examination of the leaves
and limb, proves itself to be independent of the cause that sometimes produces the pear
blight, and which Dr. Harris ascribes to the Scolytus pyri (Peck). The external ap-
pearances in the two cases are identical, and yet the causes of the blight are different :
in the one case, it may originate in the wounds of the insect alluded to ; but in the other,
there can be no doubt that it is produced by atmospheric changes resulting from heat and
moisture combined. Some of our elms are affected every season; and when the cause
operates intensely, several kinds of trees suffer in the same way : sometimes an entire
limb wilts and blackens in the course of two or three days ; and then again the disease is
confined to a few leaves, which fall off, and the limb lives ; while in yet others the edges
of the leaves dry and blacken, or one half of a leaf, the other half remaining unaffected.
I am of opinion that we should not attribute to insects a disease that runs the course above
described ; and as it occurs only in certain states of the atmosphere, it is more agreeable
to analogy to assign the cause to which I have referred it.

CHAPTER XVI.

ORDER VI. HETEROPTERA.

Tus order embraces those insects whose forewings or wing-covers are coriaceous at the
base and membranous at the apex ; the body is depressed ; antenn# elongated and filiform ;
and the mouth, which is placed on the inferior part of the head, is promuscidate. Meta-
morphosis semicomplete, with an active pupa state.

It is the Hearprena of most American and English authors ; but Hergrorrena is the
designation preferred by Westwoop, for reasons which make it appear to be the more
appropriate name of the two.

The order is divided into two sections : 1. Hypnoconisa, the residents of water ; 2.
Avnrocorisa, those which breathe air.

We have three families at least under the first section, the Noroyecrips, Nepipx, and
GatevLipa.

The Genus Noronecrvs is not uncommon in the springs that furnish the city of Albany

with water, and which rise in a high sandy plain some four miles west of the city.

Notonectus
Body much depressed ; mouth promuscidate, short, and composed of two joints ; antenne
lost in the specimen ; eyes ovate : the forelegs advanced, and the tarsi armed with a
single two-jointed claw ; the middle and posterior three-jointed ; the third minute,
and the last armed with two claws. Color brown or olive brown; beneath lighter
than above, uniform, and without ornaments or spots. Thorax in the form of a segment
of a triangle; middle impressed with a longitudinal line, crossed by a transverse
groove ; margin of the thorax ciliate. Scutellum large ; base rather greater than the
height : the posterior pair of legs obscurely barred with brown ; forelegs raptorial,
and without bars. Length an inch and a quarter. Swims rapidly upon its back, and
is carnivorous.

The damage which the .Votonectus occasions, consists in the destruction of young fish,

or fry : in this respect it is as voracious as the Dyticus.

FAMILY HYDROMETRID®. 167

Gexus GALGULUS.

Body short, dilated ; antenne short, terminated with a round knob, and placed in a cavity
beneath the eyes ; eyes subpedicellate ; mouth promuscidate ; head triangular ; arm
or humerus dilated ; tarsi single-jointed, armed with two claws : on the hindlegs, the
tarsi are two-jointed, and armed with a double claw.

GALGULUS OCULATUS.

Color brown or dark brown : head vertical, appears truncated before ; eyes somewhat
kidney-form, elevated, with their front and sides formed for vision. Head and thorax
rough or warty ; posterior edge of the thorax thickened, and edge ]uteous, emarginate.
Scutellum large, traversed by a ridge, and impressed with a line upon its middle ;
sides tubereulated : the whole appears rough. Wing-covers rough, with two or three
rows of small tubercles running parallel with the sides. Forelegs placed in front,
raptorial, and with a large dilated humerus : thighs of the middle legs somewhat
dilated ; hindlegs long and slender, the two last pair are banded. Length rather less
than a quarter of an inch. }

Resembles a small toad, and inhabits muddy places, where it may be seen running, and
sometimes leaping. I have found it in great numbers in the latter part of May, running
and hopping upon the mud beside streams of water.

Hydrometridae.

Tue habits of the Hypromerripm are peculiar. Though they have wings, they scarcely
ever use them. They do not live in water, nor upon the land. In the spring, summer and
autumn, almost every running stream, and pool connected with it, will furnish many
individuals of this family, which, from their mode of progression over the surface of the
water, have been called skippers. Their legs are long and angulated, and their bodies are
raised considerably above the surface over which they glide. The antenne are long and
slender, and the surface of their bodies is protected from the wetting action of water as
perfectly as if varnished : a skipper, immersed in water, comes out as dry as if it had
been protected by an india-rubber coat. The surface of the insect, examined under the
simple lens, is bright and glossy or lustrous, from the presence of a close nap, which is
doubtless the means whereby the water is repelled.

The antenne are four-jointed ; the first longest, and in the Grrris they are placed
directly before the eyes. The forelegs are very much advanced, and seem to belong to the
head, but are still attached to the breast ; the tarsi are two-jointed.

The appearance of the Gerris is not very much unlike that of Reduvius, and the forelegs
might be used for grasping. Gerris marginatus is the most common species. Dr. Harris

enumerates only three species. The insect lives upon other smal! animals, which it can
capture, and never upon the juices of plants ; it is not known how it provides for its
security during winter. It moves upon the water by a kind of rowing motion, but without
immersing its feet.

Reduviidae.

Owe of the obvious characters of this family is the constriction behind the head, which
makes it appear to be prolonged or extended behind into a narrow neck. The eyes are each
accompanisd by a single ocellus. The antenn# are sometimes prolonged and slender ; in
other cases, short. The thorax is often armed with a lateral spine. The legs are long, and
the forelegs rather stouter and raptorial : tarsi three, and sometimes quite minute.

Repvvivs ——. ( Plate vii, fig. 3 )

Basal joint very short ; second joint longer than the head and neck, two-thirds as long as

the whole organ ; fourth longest, slender ; proboscis as long as the head and neck,

stout : tarsi three-jointed ; joints minute. Body elongated, narrow : thorax armed

with two lateral spines, and in front transversely ridged : wings large : legs long
and hairy.

Repuvivs ——. ( Plate xxix, fig. 8.)
Color brown. Body elongated, oval or dilated behind : humerus dilated and banded, and
forelegs raptorial : eyes prominent : thorax faintly striped longitudinally : abdomen
ovate ; its edges spotted with red, brown and white, the brown oblong spots occupying
the greater part of the margin : legs brown.
This species is rather common upon low bushes during the month of September, in the
vicinity of Albany.

HamMarocervs PURcIS. ( Plate xxx, fig. ~“
Cimex rvurcis (Drary). Repvvivs myatnemervs ( Illiger).

Head, eyes, thorax, abdomen, and legs black : antenn# setaceous, with numerous jolnte
seutellum large, triangular, black ; corium white, terminal membrane black : wings
white and transparent : edges of the abdomen marked with scarlet spots : rostrum
black and short : thighs of the hindlegs scarlet ( Dauny, Vol. iii, pl. xlv, f. 4).

This is not an uncommon species : it is frequently met with in autumn upon plants
growing in shady places.

FAMILIES LYGZIDA AND CIMICID. 169

Lygeide.

Antenn# are four-jointed, inserted directly on a line drawn from the eyes to the base of
the rostrum. The body is narrow. The membranous portion of the hemelytra is furnished
with about five nervures : tarsi three-jointed.

The species are small in size, and resemble the Core1p in form : some are marked with
bright colors.

To this family belongs the chinch-bug, which figured so largely in Wisconsin in 1845,
and was described in the Prairie Farmer. According to Dr. Hanxis, it is the

Lycmus Levcorrerus (Say). Whitewinged Lygeus.

This insect I have not seen. Its wing-covers are white, marked with an oval black spot
on a central line. The body is black and downy ; the beak, legs, antenne at the base, and
hinder edge of the thorax reddish yellow. Length three-twentieths of an inch.

The young and immature are bright red, but change to brown and then to black, and
always marked with a white band across the back ( Harnis).

It appears that the wheat and cornfields of the West have suffered severely from this
insect.

Cimicide.

Tue next family has received the name Crmicrp», and contains the bedbug, an insect too
well known to require any very minute description for its identification.

Crmex LecruLartivs ( Linneus).
Body depressed or flat : antenne four-jointed; thorax sublunate ; abdomen circular ;
wings rudimentary, scale-like ; tarsi three-jointed.

The history of this bug is not uninteresting, and it is not yet decided what country is
entitled to the honor of having first given it birth. The-English entomologists say that it
was unknown in London, or in England, until after the great fire of 1666; and it is as-
serted by some that it was about this time introduced into England from America, in the
fir timber imported to rebuild the city. This is partly sustained by the fact that it is still
unknown in some of the remoter parts of the kingdom. It is further proved that Suaxr-
SPEARE Was unacquainted with it, as no mention is made of it in his writings. Whether this
fact is decisive of the question, I leave it for others to say ; only I would observe that it
seems to me that none of its habits are caleulated to awaken poetical associations. On the
other hand, according to the statement of Wesrwoon, it appears to have been known as
early as 1503.

{ AcricunruraL Report — Vot. v.] 22

170 na ORDER HETEROPTERA.

The cheapest, cleanliest, and best way to get rid of the bedbug, is to employ a satarated
solution of salt in water. The free use of salt will drive them from the bedstead to the
covering, and to chinks in the wall or floor; whither the solution must follow them, or
the remedy will fail, as often happens with others that have been recommended, and for
the same reason.

If all is true that is affirmed of this bug, we cannot deny that its instincts are of a high
order. If, for instance, it is unable to mount the bedposts, it elimbs the walls and gains the
ceiling, and, when it has reached a position immediately above the sleeping individual,
drops down upon him. This devising of means to accomplish an end, shows the insect to
possess a high instinctive power. It is also a curious fact, and one worthy of note, that the
bedbug is only found in a domesticated, never in a wild state.

The favorite food of this inseet is blood, but it is not confined to this diet : hence it
subsists, and continues to perform the common functions of life when deprived of blood.
Any albuminous matters elther in a wet or dry state, juices of wood, ete. ete. suffice it
when its favorite source of food is inaccessible. It is, however, said, upon high authority,
that mahogany, walnut, oak, and cedar are fatal to these bugs; and that when
in a box made of either of these woods, they speedily perish.

Their powers of increase are considerable : a female lays at four different periods d
the year, and produces about fifty young bugs at each litter ; so that at this rate, if
fortunate in escaping the persecution of the housekeeper, she will rear two hundred a
year. The young attain their full growth in eleven weeks. It requires, therefore, consider-
able diligence and activity to get ahead of this little foe to quiet and comfortable repose.

Fumigation with sulphur is an effectual remedy against bugs when they infest the en-
tries, woodwork, or crevices of old houses, or when intolerably numerous in the cabins of
vessels. ,

Coreide.

Tue Cousins: resemble very closely the Reovviins ; but it requires only a slight compari-
son of the families, to be satisfied that they are essentially different. The species of the first
named family are characterized by the last joint of the antenne, which is either thicker or
longer than the others. The joints are still four in number, and are inserted near a line
running from the eye to the base of the rostrum. The rostrum is three-jointed, and the
middle joint is the longest : in some of our species, it extends to the base of the hindlegs.
There is an ocellus near each round eye. The hemelytra terminate as usual in a membrane
more or less diaphanous, and in this family they show numerous longitudinal nerves. The
margins of the abdomen are not concealed or covered by these organs, and hence they may
often be seen slightly projecting in the form of a sharp edge. The tarsi are three-jointed.

FAMILIES COREIDA. AND SCUTELLERID. 171

We have many species belonging to this family. Probably no one, who has ever been
engaged in gathering our small fruits, but has observed these narrow or rather elongated
bugs, some of them ornamented very elaborately with bright colors, as for instance the
red and yellow that border their elytra’ and superior surface.

Genus COREUS.

‘Antenne four-jointed : second and third longest ; the fourth rather enlarged or thickened,
and shorter than the second or third. Sides of the thorax not dilated’ ( Westwoop).

Corevus Tristis. Squashbug. ( Plate vii, fig. 1.)
Color dark brown, rusty brown, yellowish beneath : head marked with a red line ex-
tending to the front of the thorax ; two others, parallel with the former, pass by the
side of the eyes. Thorax roughened with elevated black points, concealing the red
ground beneath : lateral edges also reddish ; posterior angles rounded, and base
broadly grooved transversely. Membranous part of the hemelytra black, and showing
numerous longitudinal nervures. Beneath rusty ochre-yellow, and each segment of
the abdomen marked with a row of black points near the outer edge, and a parallel

row of small black spots, the latter rather obscure.

The squashbug is a common insect in gardens and fields, and is found not only on squash
leaves, but upon those of the pumpkin also. It is injurious by inflicting numerous pune-
tures upon the leaves, which cause them to wither and dry, and, if the plant is feeble, will
destroy it. The first remedy for the effects of minute wounds of this kind, is to cultivate
highly, so as to impart to the plant sufficient health and vigor to resist injuries by a rapid
growth. If this does not answer, it will be necessary to find the insects and destroy them
under foot, before their eggs are deposited for the new brood. The eggs are laid about the
last of June, by the insects that have survived the winter. During the summer, it will
frequently happen that the young appear at different times, and they may be found col-
lected together in little groups.

Seutelleridae.

Tus family is perhaps better known through some of its species than others. The dis-
agreeable smelling bugs that frequent berry bushes and strawberry vines belong here.
They are depressed and of an oval form, and are furnished with a very large scutellum.
The rostrum is composed of four joints, instead of three ; and the antenna sometimes has
five joints, but not always. Two ocelli are always present, and the tarsus is three-jointed.

Of this family, the Genus Penratoma is one of the most common, and feeds upon the
juices of plants ( Plate vii, fig. 2). Sometimes it has only to pass over a fruit, to impart to
it its offensive odor.

CHAPTER XVII.

ORDER VU. DIPTERA ( Anistortze).

ANTLIATA ( Fannicrvs). HALTERIPTERA (Cramvitre).

Tux obvious characteristic of this order is the possession of two wings only, and a pair of
small knobbed appendages just behind them, which are called Aalteres or poisers, as in the
common fly. The wings are membranous and placed upon the mesothorax, and, when at
rest, remain expanded as in the Hymenorrena ; that is, they are never folded upon them-
selves. The tarsi are five-jointed. The mouth has a fleshy proboscis, which is merely a
modified labium. This proboscis encloses several lancet-like organs, capable of penetrating
flesh or the softer parts of vegetables : the mouth is therefore suctorial. In a few genera,
as the (Estavs, the mouth is closed. The thorax is compact, and the prothorax is reduced
to a collar. The wings, which represent the fore pair in other four-winged insects, are
membranous, naked, or rather clothed with scales. The dise is divided into a moderate
number of areolets, by the inosculation or junction of the nervures or veins.

This order of insects is clearly separated from each of the other orders : where some
species belonging to the Order Nevaorrera are deprived of a pair of wings, they may still
be distinguished by the absence of Aa/teres or balancers. The jaws of the diptera are never
formed for biting or nipping : so the neuration of the wings of the diptera are quite dif-
ferent from that in the other orders.

The size of the individuals composing this order may be called small; but what is
lacking in this respect is more than made up in numbers, and this whether we take into
consideration the number of species, or the vast number of individuals that sometimes
swarm together. ; .

Some of the diptera have domesticated themselves in our dwellings, to the great an-
noyance of all good housekeepers ; and notwithstanding the brush and the broom is freely
used to drive them away, they seem to entertain no fears of the consequences of returning
to their old quarters. Arsenic fly-powder, and all the various traps that the ingenuity of
man has yet devised, have not thinned the ranks of the housefly. Wherever man goes, the
fly follows in his steps, and makes a free use of his dwelling whenever the weather with-
out becomes uncomfortable.

FAMILY TIPULID. 173

It is scarcely necessary to say that many of the diptera, though small in size, are great
annoyances to man and animals : the estrid@ are perpetual torments to our domestic ani-
mals ; and musquitoes, in the warmer regions especially, are so troublesome as to require
special means of protection from their stings.

The transformations in this order are incomplete. The larve are white and fleshy, cy
lindric, and without feet : they are usually called maggots.

Tipulidae.

Genus CECIDOMYTA,

It is a very curious fact in natural history, that the most serious injuries the crops of the
husbandman receive are inflicted by insects the most minute and insignificant in size : the
very weakest among the tribes of animals are the greatest destroyers of the products of
man’s industry. The whirlwind or the hailstorm, it is true, sometimes sweeps over his fields
of wheat and corn, or a flood of water may pass over them, and leave desolation in its
track ; but these terrific visitants are harmless in comparison to the tiny fly that sports
and dances over his grain-fields. With all our wisdom, we have not yet devised a weapon
to extirpate this foe, nor a defence to secure us from its ravages : our most successful
efforts have been but failures; and were it not for the aid of the elements, or the secret
influence of an unseen but benignant hand, the foe would maintain the field in the face of
him who has subjected to his will the proud warhorse and the colossal elephant.

Cecrpomyra is the generic name of these destroyers : they are flies, each with two wings,
antenne, poisers, ete. Several species have been described, one of the most prominent of
which is the C. destructor of Say, the hessian fly. The genus is characterized by the joints
of the antenne being variable from fourteen to seventeen : the form of the joints in the
female also differ from their form in the male ; the former being oval, and the latter glo-
bular, but both are furnished with hairs issuing from the joints in the form of a whorl
(See Plate iv, fig. 1). Wings three-nerved, ciliate or fringed : joints of the tarsus short.

Crctpomy1a pEsTRucTOR. Hessian-fly. ( Plate iv.)

This species is black, except that the abdomen is only tawny, though each ring is more or

less black : legs pale red or brownish, with black feet. Length of the body one-tenth

of an inch : the expansion of wing rather exceeds the length of the fly. See fig. 1 c,
which represents the natural size of the Cecidomyia destructor.

The hessian-fly has occasioned as much controversy as any species in the insect kingdom.

I published in the American Journal of Science in 1846 — 47 an article furnished by Dr.

Fircn, which contains all the important facts in its history. I deem it, therefore, unneces-

sary here to go over all of the ground occupied by that paper.

174 ORDER DIPTERA.

As regards its origin, it appears from the numerous accounts published at different times
during the last half century, that the hessien-fly is not indigenous to this country, but was
imported in straw from Europe by the Hessians in the employ of the English government
about the year 1776. The facts which go to sustain this view of the question are, that an
insect had appeared in Germany, and committed ravages upon the wheat erop prior to its
appearance in this country ; and that the habits and characters of this german insect agree
with those of the one named in this article. It is farther shown by the history of its pro-
gress in this country, that it was first observed upon the western extremity of Long Island,
and on Staten Island, in the immediate neighborhood of the grounds occupied by this
branch of the English army ; and that from this centre it spread in all directions, travel-
ling slowly over the cultivated parts of the country, and destroying the wheat crop in its
course, Its march, and the consequent destruction of the wheat crop, was marked by an
increase in its numbers, and in the amount of its injury for an uncertain number of years,
when it gradually disappeared from the country it had oceupied and wasted. After long
intervals of freedom from the ravages of this fly, it gradually returns and renews its at-
tacks upon the wheat crop, running about the same course in its second as in its first
visitation. It has very recently passed over parts of Maryland and Virginia. I observed it
in the former State in 1849. I think we may infer from its history and progress, that in al
parts of the United States where wheat is cultivated as a staple produet, it will continue
its injurious career hereafter as in times past.

The species of fly which has received the name Cecidomyia destructor from the distin-
guished entomologist Say, possesses the following specific characters : Fraae, head black,
flattened, globular ; antenn# about half the length of the body, and composed of sixteen
oval joints furnished with a whorl of minute hairs, the two basal joints close and globular,
terminal joint the longest ; palpi three-jointed, hairy ; thorax black, oval, broadest behind
the wing-sockets ; scutel black; poisers only dusky; abdomen black above; sutures
tawny fulvous, elongate ovate, scarcely equalling the thorax in width ; ovipositor rose-red ;
wings dusky, fulyous at their base ; legs equal, pallid brown ; tarsi black, equalling the
legs in length. Mace ; antenne three-fourths the length of the body ; joints globular,
and furnished with hairs as those of the female ; filaments separating the joints, about as
long as the joints : abdomen brownish black, cylindric, seven-jointed and slightly tapering,
the extremity armed with two robust processes having incurved hooks at their tips.

It appears from Dr. Firen’s statement, that in the spring the perfect insect remains but
about a week, during which time it deposits its eggs for the summer brood. The first brood
appears about the first of May in Northern New-York, and of course is hatched from eggs
that were laid the preceding autumn ; the insect having subsisted upon the juices of the
herbage, or lain in a dormant state from that time. Early in May, then, the fly deposits
its eggs, in the same field, upon the more succulent leaves, near their insertion with the
stem of the plant, which it may readily reach after being hatched. After a time the worm

FAMILY TIPULID®. 175

is found attached to the stem, near or upon the first and second joints. Dr. Fircn remarks
that the second brood is less injurious than the first, in consequence of the more advanced
state of the grain and the firmer consistence of the stalk. The worm, by its irritation,
diverts the current of flowing sap to itself, and produces an enlargement of the stem at
the place where it is attached. The culm is weakened by the change of structure that has
taken place in consequence of the numerous worms usually congregated near its base.
By the first of June, the worm has changed into its flaccid state ; and about the last of
July, or early in August, the mature insect, the fly, appears for the second time. This last
brood of flies is now ready for the young wheat that may be sowed, upon the leaves of
which they deposit their eggs, and there finish their transformations so as to appear in
New-York the last of April.

Thus careful observation has proved that but two broods appear during the year, though
it has been maintained by some observers that there are three. This latter opinion seems
to have arisen from the fact that an entire brood does not appear at once, or on the same
day, but the fly may and does continue to come forth for as many as ten or twelve days
after the first of the brood are hatched.

The most important question which stands connected with the hessian-fly, is, By what
means shall the farmer protect himself from its ravages? Now we have very slight grounds
for expecting, or even for hoping that a remedy will ever be found that shall meet our
wishes in this respect. The evil is rather to be warded off by a judicious use of means that
are related to the habits of the fly, and to the habitudes of the wheat plant itself. When
a district, however, is extensively affected, the true course undoubtedly is to cease cul-
tivating wheat, and perhaps barley also, until the fly has disappeared. e

Recurring to the habits of the insect, the most significant are the time of its appearance,
and the time it continues in its perfect state, during which it is engaged in laying its eggs,
an operation, the exact time of which it is essential for us to know in this case ; and it is
a law of nature in the insect class, that when swarms are produced, they come forth at
regular periods of time. The habits alluded to are well known in the case of the hessian-
fly. As to the time when the insect appears, it is established by observation that about the
first of May, or at time in the spring when the earliest trees and plants are flowering, this
fly is maturing, and comes forth near the time specified ; and the first brood is hatched
from eggs laid in autumn. These two facts unite to suggest the same precautionary measure
to be taken for the eradication of the fly from both the winter and the spring crop, name-
ly, to delay sowing the grain until the fly has disappeared, or to that period when the
plant will come up too late for the deposit of eggs upon it. Experience has proved the
efficacy of Jate sowing in both kinds of wheat.

Another remedy is connected with the place where the eggs are deposited, and where
the transformations are undergone. It seems established that the real hessian-fly deposits
its eggs upon the young leaf, near the stem, and near the base of the stem. The consequence

176 ORDER DIPTERA.

is, that in reaping or harvesting the grain, the straw is cut abovethe place where the larve
or eggs are usually found; and it would be well, in all cases where the fly is found, to
eut the straw higher than customary. Now if the stubble is turned under for the next crop,
a large proportion of the eggs will mature, and the succeeding wheat-plants will form a
habitation for the forthcoming August brood ; but if the stubble is first burned, the eggs
will be destroyed, or but few will eseape. The objection to this summary remedy is, that
it also destroys those little insects that prey upon the hessian-fly. I deem this a very light
objection, for the fire will destroy hundreds of eggs where the enemy of the fly would
devour one. Burning off the stubble, then, must be ranked among the best palliative means
for saving the wheat-crop.

There are also two remedies having relation to the habitudes of the wheat itself, and to
its varieties. It appears to be established by observation that some varieties are less subject
to injury than others, or indeed that some are nearly fly-proof : this is one of the earliest
facts on record, and all experience hitherto has fully sustained it; the straw of these
varieties being too siliceous to allow of a ready lodgment and home for the larva of the
fly. The other remedy here alluded to, rests on the practicability to push forward and
mature the plant sufficiently to give it strength to resist effectually the injuries the stem
receives from the maggot in its flaccid state. High cultivation should be called to our aid
here, and it undoubtedly will prove a very efficient safeguard ; its effects are twofold, as
exhibited in an augmentation of the power of the plant to resist injury, and in the produe-
tion of a better crop; so that the remedy is not entirely lost, even if it does not succeed
in the way we wish. ;

Objections have been made to the first two remedies above proposed : for instance, by
late sowing, the grain is liable to be winter-killed ; but would not this risk be greatly
diminished, or even obviated entirely, by drilling in the grain ? The burning of the stubble
is objected to, because it destroys the parasites of the fly ; but this, as I have said before,
is searcely an objection ; while for the utility of the remedy, we have the testimony of
Hanrais, Herrick and Hanavs, the latter of whom originally proposed it, and the two
former are entitled to the highest consideration as observers and men of science.

Of the numerous applications to the grain crop, for the purpose of killing the insect
directly, I have no faith. Rolling the seed in plaster ; steeping it in various salts ; sowing
lime, ete. over the field of young wheat, are beneficial remedies in an indirect way : they
give vigor and strength to the plant, and hence are useful as palliatives.

Cecrpomy1a tritict. Wheat-fly.

This species is very distinct from the hessian-fly : its habits sufficiently show this dif-
ference ; and the remedies which are in some degree palliative in the case of the hessian-
fly, are valueless against the Cecidomyia tritici. Among its peculiarities, some of the most
remarkable are that it deposits its eggs in the wheat-head, and undergoes its metamorphoses

FAMILY TIPULIDZ. 177

in the soil; and that the mature animal is engaged longer in the work of depositing its
eggs, than is the hessian-fly. These distinctions must govern our attempts to guard against
the attacks of these insects.

The wheat-fly possesses the following characteristics : Body orange ; wings transparent,
rounded at the tip, ciliate, or fringed with minute hairs. Fema.e, the antennz are beaded ;
joints twelve, whorled with hairs ; eyes black : length about one-tenth of an inch. Maes,
the antenne with twenty-four joints, globular, and whorled with hair as in the female :
size somewhat variable, but less than the female. Its general appearance is that of an
orange-colored gnat.

The first account of this insect was given by Mr. Jewert, in the nineteenth volume of
the New-England Farmer, 1820. According to Judge Buen, it was observed here in 1828.
Its first appearance in this country was in the eastern part of the United States : several
of the Eastern States, and the Canadian provinces, have been visited by it. The cultivation
of wheat was suspended for many years, in consequence of its injurious attacks.

The time of the appearance of this fly varies according to the situation of the country,
being in some places early in June, and in others as late as August ; indeed, according to
Mr. Harris’s Report, as late as the 20th of August. The first half of July, however, is the
period when the largest number of eggs is deposited ; a period which, in New-England,
would find the spring and winter grains in the best state for receiving their eggs. The
insects are active in the morning and evening, and appear in swarms; but during the day,
when the sky is cloudless, they conceal themselves among the grain and grass. After about
eight days, the eggs that have been deposited in the heads of the grain are hatched. The
maggots are orange-yellow, and, according to the observations of Mrs. Gace of New-
Hampshire, they attain their growth in about twelve or fourteen days : they are then
about an eighth of an inch in length, but their size is not uniform. Their number is also
variable, as many as forty being sometimes found on a single plant, and at other times two
or three only. They seem to be influenced by exposure ; for in hilly places, where the
grain is éxposed to the wind, they are much Jess numerous than in sheltered spots.

The injury that wheat sustains from the presence of this fly depends upon its state of
forwardness. As the worm is unprovided with boring instruments, it is principally during
the soft state of the grain that it has the power to do the most hurt. If the egg is deposited
so as to be hatched when the plant is in blossom, it is then capable of inflicting the greatest
amount of injury ; for at this time it is supposed to subsist on the pollen, and may there-
fore prevent the fertilization of many kernels in the same head ; and then also it obtains
the milky fluid that begins to be formed at this period, and is now accessible through the
softness of the skin or epidermis of the grain. But if the time of deposition of the egg is
such that it becomes hatched after the plant has flowered, and the kernel has acquired
some considerable hardness, the worm is incapable of absorbing nutriment, and perishes

for want of food.

_ The worms acquire their full size and perfection, cast their skins, and descend to the
ground early in August, or perhaps as late as the middle of the month. They bury them-
selves in the soil at the depth of about an inch, where they remain through the winter.
There is therefore but one brood in a season. The worm is speedily changed into a pupa,

any of them are to be effectual, it is evident they should be resorted to over the whole
district infested by the insect.

Among the remedies which seem to have been at least partially successful, is that of the
abandonment of the cultivation of winter wheat for the substitution of the spring variety,
and late sowing. The remedy operates on the principle of starvation, and would probably
be completely successful, were it not that grasses and other grains, as oats, rye and barley,
offer suitable recipients for the eggs of the insect, and furnish nutriment for its progeny.

It is recommended to smoke them out. To carry on this plan of warfare, the flies must
be attacked in the evening, when they rise from their lurking places in the depths of the
grain. Brimstone, mingled with other combustible matter, should be burned in a position
to give them the full benefit of the smoke and vapor when they rise upon the wing, and
hover over the grain.

Another recommendation is to sow fine quicklime over the field when the heads of the
grain are moist : this may be repeated several times.

It is recommended by Dr. Frren to first catch,and then kill them. The method of doing
this is sufficiently simple and easy, and deserves a trial. Take a long rope, attached to a
wide open tight bag ; and let two men, one at each end of the rope, pass through the field,
dragging the open wide-mouthed net over the heads of wheat. Go over the whole field in
this way, and millions of the fly will be caught if the net or bag is properly managed.

Deep ploughing is also a remedy that deserves trial, and indeed has been tried and
followed with success, This, of course, is to be resorted to after harvest : the @bject is to
bury the insects so deep that they will be unable to find their way out of the ground the
hext season.

The Cecidomyia which has appeared in this country is now regarded as identical with
the C. tritici of Europe, which has been known in England and Scotland for two-thirds of
a century, and was described at an early period. In this country, especially in the vicinity
of Albany and in the county of Berkshire in Massachusetts, it has been disappearing gra-
dually for the last ten years, and the wheat crop has again become a profitable one ; and
the probability is, that with our present knowledge of its habits, and of the means for its
extirpation or for ayoiding its worst injuries, we may hereafter escape its depredations.

Cecrpomy1A roprntA ( Haldeman). , ( Plate iv, figs. 3, 4, 5, 6.)
’ Color of the fly orange red; antenne: and wings dusky; thorax marked by three dark
lines : two dusky spots on the sides of the body. Length three-twentieths of an inch.
The larva is a maggot of a whitish color, faintly tinged with orange, rather deeper
towards the head : pupa or chrysalis naked, or destitute of a cocoon.
This species inhabits the locust-tree, and was first described by Prof. Harpeman*. The
Jeaf becomes thickened on its edge, and rolled over ; and thus a cavity is formed, which
contains two or three larve of this species.

Crcipomyra saticis (Fitch). Willow Cecidomyiat.
Color of the fly black above, paler beneath and downy ; wings smoky ; legs gray. Length
of the body, one-fifth of an inch ; expansion of wing, three-tenths.

Inhabits a reddish gall upon the low willow bushes of wet places : it is of an oval form,
three-fourths of an inch long, and is terminated by a conical beak. Within a silken lined
cavity, early in the spring, there will be found a single orange-colored maggot one-fifth of
an inch long. Soon it changes to a pupa, but without moulting ; and in a very few days it
passes from its prison, after casting the pupa skin, and takes the winged form. Its size,
together with the rapidity of its changes, renders the species an interesting object of study.
Its damage to the basket willow is but slight.

Cecrpomy1A cuLmicota ( Morris).

The C. culmicola is a provisional species, whose habits have been investigated by Miss
Marcaretra H. Morais, by whom also it was discovered. Its habits are quite different
from those of either of the foregoing species. The fly lays its eggs upon the grain, in or
over the germ, where they remain unhatched until the grain germinates ; but when the
plant is three or four inches high, the worm may be seen, by the aid of a glass, feeding
above the top of the joint in the centre of the culm, until it is ready to become a perfect
insect. Iti is said that the pupa resembles that of the C. destructor.

‘As the fly deposits its eggs early in June, it is difficult to understand why they should
remain unhatched so long, or until the future germination of the same ripened grain after
it is sown, and then to feed upon the culm ; for it is the usual habit of flies to deposit their
eggs near or upon the magazine of food on which the larve are to subsist.

It is an interesting fact that most, if not all of the species of Cecidomyia are preyed upon
by some one or other of the family of Icunevmonipes while in the larva or pupa state.
These parasites deposit their eggs within the body of their victim, where they are hatched
in due time, and the larve subsist upon and destroy the body before its change into the

and their excessive multiplication prevented. No doubt, also, anfavorable seasons operate —
as a still greater means for preserving a balance between excessive multiplication and

entire extirpation. wi

Dr. Excurs, of Albany, has furnished me with the following communication respecting
the platygaster, a minute ichneumon fly. His remarks, and the facts stated, illustrate in a
striking manner one of the most important features in the insect world, the checks which
are interposed to the excessive multiplication of the injurious kinds.

Pratycastrer trrece (Kirby). Wheat-midge Parasite. wnery

This insect, though exceedingly small in size, has claims to our consideration, which
should justly entitle it to an exalted station in the rank of public benefactors ; at it has
had assigned to it the peculiar and important duty of keeping in proper subjection that
unrivalled pest of our fields, the wheat midge (Cecidomyia tritici).

The female fly of this parasite bears some considerable resemblance to the winged ant,
and may frequently be seen in our neighborhood during the months of July, Angust and
September, in the greatest profusion, when our pernicious devastator is most numerous ;
flying about the grasses, or running over the grains of wheat in search of the midge larva,
for the purpose of depositing in each a single egg, and by this means preventing an im-
mense number of them from developing themselves into a perfect state; although when
seen thus abundantly, they have often been unjustly aceused of being themselves the
authors of the mischief.

This insect expands to only one line and a half in breadth. The »
female is of a shining pitch black color, with long, ten-jointed,
flail-shaped anterine or horns, slightly clubbed at the ends. The
head is round or globose, with the eyes conspicuously placed on
the sides. The trank is oval, and bears a sentel terminated by a
strong rusty spine. The body or abdomen is obovate, small, and
narrowed at the base, with a long curved oviduct, concealed, when
unemployed, in the abdomen. It has four transparent wings without nervures, the superior
pair very large; and the legs are strong, and of a bright ochreous color, with the thighs
and shanks clubbed : the feet are long, slender, and five-jointed. .

We regret that some means have not yet been discovered to multiply this interesting
little insect, and thus effectually preserve our wheatfields from the fearful depredations
of the midge. James E:cnrs.

FAMILY MUSCIDA. 181

Muscidae.

Tue character of the mouth and its organs restricts and defines this natural family : it is
formed by a distinet proboscis, which is thick and membranous, retractile,and terminated
by lateral lobes; and it encloses two setiform organs and a pair of palpi. The antenne
have but three joints, the third of which is the largest, and is prolonged into a seta or
long slender bristle, sometimes articulated with its base. The nervures of the wings are
few, and extend to the margin.

The true flies feed upon both vegetable and animal substances. The common housefly is
typical of the family, and its habits in some respects are very well known. They are all
small : their larve are white, soft, and without feet, and are usually called maggots.
Meicen, it is said, has described 1700 European species ; from which we may infer that it
is a large family.

This species appears in New-York in July, and is most common in woody places, but is
often in open pastures, and frequents roadsides, alighting on horses and cattle. In New-
York and New-England they are too few in number to occasion tmuch trouble, though
their probosces are armed with lancets sufficiently long and sharp to wound cattle severe-
ly. Were they as numerous as the smaller kinds of flies, our pastures could not be occupied
during the months of July and August.

abdomen dark pinatibeonts ; spines of the middle legs two ; breast hairy.

The lighter part of the abdomen appears as if covered with a whitish bloom. The eyes
are very large, and meet at their lower edges, but are separated above by a narrow yel-
lowish space : their color is black and bronzed. Length seven-eighths of an inch, or
nearly one inch ; expansion of wings, nearly two inches.

This species is rather smaller than the plumbeus, with wings less robust and strong : it
appears at the same time, and attacks cattle and horses in the same savage way. Both are
found as far south as Maryland.

Sooty black. In some lights, the abdomen above is glaucous ; beneath, it has a shade of

greenish blue : eyes faintly bronzed. Face obsolete, in consequence of the great ex-

tension of the eyes, which meet on the top, divaricating only just above the base of

the antenne, leaving a small triangular area through which the median line passes,

and which is also traversed transversely by two grooves : this area is oceupied by six

or eight little glossy eminences. Legs and breast covered with a jet black pubescence.

The form of the eye is remarkable ; the top of the head being capped, as it were, with

the organ, which projects directly in front. The insect differs entirely from the two pre-
ceding species, and has not probably received a specific name.

This species, so far as my observations extend, is a rare insect in New-York. It is easily

distinguished by the yellow segment of the abdomen referred to, which extends only to

the sides, the inferior part preserving the black color of the remainder of the organs. Its

larva is a white maggot, and exists in decaying stumps and logs. It is usually found in the

forests in its perfect state in midsummer, and is one of the largest dipterous insects of
New-York.

; ORDER VIEL. NEUROPTERA.

Tue wings, in this order of insects, are made up of a fine network, membranous, and
usually naked and without down or scales ; they are subequal or equal. Sometimes the
lower wings are broader than the upper ; but, if narrower, they are longer. The mouth is
fitted in some families for mastication, particularly in the libellulida, which are furnished
with transversely movable jaws. The abdomen is usually long, but is destitute of a sting.
The antenn® are not uniform in the different families : in some they are long ; in others,
short. They have two or three simple eyes. The trunk is formed of three segments closely
united : the abdomen is sessile. The larva has six feet. The metamorphosis is not always
complete. ie

The order contains several well-known families, as the dragonflies, mayflies, white ants,
and the ant-lion flies. In all these families, as well as in those not yet mentioned, the wings
are formed of a fine network of nervures, so arranged in the minute details of structure
as to constitute a great number of areolets of much beauty.

In this order there is one family, the termitides, which are extremely interesting in their
economy and habits, as well as an instance of a remarkable development of the faculty of
instinct : they are social, and live in large communities ; while most of the other families
are solitary, and do not construct habitations for the common convenience and defence.

Libellulidae.

Lisextvtis: is the family name of the dragonflies : they are insects which become familiar
to every body, and are frequently called darningneedics or devil’s-needles. Their heads and
eyes, especially the latter, are always large : their bodies are long; the thorax is thick
and strong, and the abdomen long and rather slender, though not always so, and is ter-
minated by two inarticulated appendages. The antenne are short. They have three ocelli :
two lateral ones, and one seated in the median line. The mouth is well formed, and the
mandibles are strong and horny. They have four wings, which, when at rest, are extended
horizontally or carried over the abdomen.

FAMILIES LIBELLULIDZ AND MYRMELEONID®. 185

The libellul# are widely extended in their distribution : they are voracious in their
habits, of strong muscular powers, and able to remain long upon the wing. Their larve
are quite as voracious as the perfect insect. The female deposits her eggs on the water,
while upon the wing. They may be regarded as serviceable to man, especially in their
perfect state, by feeding upon insects that are annoying, as musquitoes and the like.

The family has been subdivided into three genera by Fasricius : 1. Liren.una proper,
with wings horizontal when at rest, eyes large and approximate, and having also the three
ocelli ; the middle division of the lip is the smallest, and the abdomen is ensiform. The
second genus is Msuna, having two ocelli situated on a transverse keel-formed elevation ;
the intermediate lobe of the Jabium larger than. the lateral,and armed with a strong tooth
and a spinous appendage ; abdomen narrow and elongated. The third genus is Acrion :
it carries its wings perpendicularly when at rest ; the middle lobe of the labium divided
in two; the antenne with four articulations : there is no vesicle upon the forehead ; the
ocelli are equal, and the abdomen filiform.

LIpELLULA PULCHELLA. eS ( Plate xv, fig. 5.)
Color black. Abdomen sometimes wholly black both above and below, and sometimes
light slate above and black below, or partly slate color : individuals seem to vary in
this respect without regard to sex. Wings marked by three black or dark brown spots
or bars : the basal is confined to the costa,and does not extend to the posterior edge ;
the external covers the apical area, and sweeps around so as to forma cireular curving
edge towards the base.
Fig.4 is closely allied in its habits and appearance to the pulchella, and its abdomen
presents in different individuals the same varieties of color.
Fig. f. Larva of the Libellula,

Myrmeleonidae.
( Plate xxxiii, figs. 4, 5, 6, 7.)

A ramity of insects familiarly known under the name of ant-lions, while in the Jarva
state. The insect has always arrested the attention of the curious, from its peculiar habits,
the singular form of its larva, and the ingenuity it displays in making traps or pitfalls
to catch the prey that must serve for its sustenance. In its perfect state, it resembles a
Lisetiura ; but when it is in its larval form, we would by no means suspeet that it
belongs to, or is the embryo of one of the most beautiful of the insect tribes. There is
always, however, a wide difference between insects in these two states.

In the family of the Lisetiuxipa, the larva is aquatic, and is provided with the ne-
cessary form of mouth and mandible to seize and devour other insects : it is in fact a
voracious animal, and carries on its depredations in the water ; while in the Myrmexeo-

[Agricuttorat Rerort — Vox. v.] 24

186 ORDER NEUROPTERA.

wipa, the larve are terrestrial, and the parent insects select for their habitations the places
farthest removed from water, the driest sand being the only material suited to their habits
and mode of life, or adapted to their essential wants.

The ant-lion, which is the common name of the insect about to be deseribed, is a spider-
looking animal, having a thick, short, and full abdomen, and narrow and elongated front,
which is terminated by two long or exsert mandibles, strongly toothed upon their inside
edges, and also perforated, so that the insect may suck the juices from its vietims ( See
Plate xxxilil, fig. 2 : larva). The mandibles have three teeth each, and a row of stiff
bristles below them, probably used partly for supporting their prey, when engaged in the
act of suction. The mandibles are curved, and as sharp as a needle ; and in this respect are
well adapted to the office they are designed to fulfil, the piercing or transfixing the ant,
which seems to constitute their favorite food. The three teeth are slender, and but slightly
thickened at the point of junction with the jaw. The body is clothed with a few bristle-
like hairs, but in other respects it may be said to be naked. But what is quite peculiar and
interesting in the construction and habits of our species of ant-lion, is the position and
structure of its legs ; they only permit it to move with its abdomen in front, or, in other
words, it is obliged to walk backwards.

To obtain a supply of food, the larva forms a conical depression in dry sand under a
shelving rock, where the surface will remain undisturbed ; the depression being over half
an inch in depth. At the bottom, the owner places itself concealed in the sand, with only
its mandibles standing a little above the apex of the depression. Now as sheltered places of
this kind, which the ant-lion selects, are also excellent highways for all small animals to
travel, and especially suited to the habits of the ant, if the ant is not cautious in his pas-
sage through these dry and shelving grounds, it will probably fall into some one of these
sand-traps : this happening, there is little chance of its escaping from the jaws of the lion,
which are always open and ready to seize the unfortunate traveller. If, however, the ant
does at first escape the clutches of the lion, and attempts to clamber up the side of the
pit, it is sure to be overwhelmed with a shower of sand cast, up by its cunning foe, and
most certainly precipitated again to the bottom.

Notwitstanding this lion is furnished with strong mandibles, they are not for the purpose
of chewing or biting its food, but are so constructed as to hold its prey securely, and to
extract its fluids by suction. When this is finished, the lion tosses the empty skin from its
pitfall, by means of its long mandibles and the free and extended motion of the head in
its thorax.

Like other larva, the larva of the ant-lion changes its skin, When about to undergo its
transformation, it glues together a portion of sand by mixing it with a kind of mucilagi-
nous and fibrous or silky secretion, which it forms into a perfeetly round ball having a
sufficient consistency to bear handling freely. At the time of the final change, which
oceurs about twenty days after the ball is rolled, the pupa pierces a round hole in the side

FAMILY EPHEMERID-. 187

of its globular envelope, and comes forth, casting off its pupa skin, which is left partly
adhering to the orifice as represented in fig. 4.

The myrmelion is a four-winged insect, at first view resembling a libellula ; but it will
be perceived that its antenne are peculiar, and quite different from those of that family :
they are larger at the extremity than at the base, generally curved, and sometimes appear
like a hook. The eyes are wide apart, and do not touch upon the upper and posterior parts.
The wings are extremely delicate, like the finest gauze ; and the abdomen is rather slen-
der, and tapers each way. The color of the insect is brown. The wings are transparent, and
all the nervures are spotted with brown and white. The rings of the abdomen are brownish,
but much the darkest on their posterior half : the abdomen is also clothed with short
hairs. The wings are attached to the thorax at a distance apart, and the thorax is divided
into two parts, the first supporting the forewings, the last the hindwings : the first has
rounded eminences, separated by oblique fissures ; the last has properly only two, which
are separated by oblique ridges, that begin at the sides and nearly meet in the middle.
The abdomen has five rings. The feet are black. Length of the larva, about } an inch :
length of the perfect insect, 1} inch ; expanse of wing, 2} inches.

The species above described and figured were furnished me by Mr. J. Gesnarp, Curator
of the State Museum, and were procured under the limestone ledges at Schoharie. I have
also found the larva of the ant-lion beneath the limestone ledges near Burlington ( Ver-
mont) : almost every suitable place furnished specimens of the insect.

I am unable to determine whether this American species has been described or not.

Ephemeridae.

Mayrty is the common name for the insects of this family. If not characterized by the
shortness of their lives, it is a well-known feature in their economy : they live but three
or four hours in their perfect state ; hence the modifications of their mouth are quite dif-
ferent from those of the libellulide, which have a much more prolonged existence, and
are therefore provided with ample means for taking sustenance. Their antenne are minute
and three-jointed, and their four wings are of an unequal size. The mouth is nearly obso-
lete or wanting, and the extremity of the body is furnished with articulated sete#. Their
bodies are rather long, slender, and soft; the eyes rather large, and there are also three
ocelli placed in a triangle between the eyes. In some species the clypeus shuts over the
mouth.

The name of this family is derived from the greek ephemeros, diurnal, in allusion to the
shortness of their lives. The only function they perform is to couple and deposit their eggs
in the water. Their larve live in the water, and their existence in this state is prolonged
for two or three years. They take refuge under stones, or in the earth or mud. They feed
upon the slimy mud that contains decomposing particles of organic matter, and which
suffices for their nourishment.

CHAPTER XIX.

ORDER IX. TRICHOPTERA ( Krasy).

Tue English have given the name caddiceflies to the insects of this order. The consistence
of the body of the perfect insect is considerable, and besides they are thickly elothed with
hair. Their eyes are rather prominent and large, and they are provided with three ocelli.
Their antenn# are variable in length, being sometimes much longer than the body ; at
others, shorter. They have four membranous wings; the front ones are fibrous, and the
nerves are branching : the posterior wings are the largest, and folded when at rest. The
mouth is imperfect and unfitted for mastication, the mandibles being only rudimental.
The maxillary palpi are long, and almost setaceous. The larva has six legs : it resides in
a case in water, which it forms of little fragments of shells, or of sand or sawdust. The
mature insect is often employed as a fish-bait.

Punycangra semipasciata (Say). ( Plate xxxii, figs. 9 & 10.)

Color brownish or ferruginous. Wings ferruginous, marked with irregular black lines and
a distinet point near the inner and basal angle : inferior wings light ferruginous or
yellowish ; the hindwings have a dilated mark near the inner margin.

CHAPTER XX.

ORDER X. HYMENOPTERA ( Linnvs).

Tuts order resembles the Nevrorrera in the number, texture, and organization of the
wings ; but they have a fewer number of nervures, and are less delicate in their construe-
tion : the forewings, too, are larger than the hind ones, and their foldings are horizontally
disposed upon the back. The mouth is provided with horny jaws, and the maxille are
metamorphosed into a sheath for the membranous tongue. The eyes are large. The thorax
is composed of three consolidated segments, and the abdomen is attached to it by a pedicle
or thread, provided with a sting in the females, or terminated with a multivalved saw or
ovipositor. The tarsi are five-jointed. The larva is without feet, except in one group; and
the pupa is inactive and incomplete.

This order probably furnishes the most remarkable families for the development of
social qualities and instinctive powers; and if instinctive endowments have claims for
consideration, the hymenoptera should rank first and foremost among the insect tribes.
Some of these remarkable qualities appear in the bee, the ichneumon, the wasp, and the
gallfly.

This is the most populous of all the orders in the insect world, unless we except the
Cotrorrera ; its estimated numbers embracing one-fourth of the insect population.

Mr. Westwoop adopts the following divisions for this order :

Section I. Tereprantta ( Latreille) : the abdomen of the female being furnished with an
ovipositor, which combines the characters of a saw and a perforator or borer for
depositing its eggs.

Section IT. Acureata (Latreille), embraces those whose abdomens in the females are
provided with a sting connected with a poison reservoir. The antenne of the males
have thirteen, and those of the females twelve joints.

190 ORDER HYMENOPTERA.

The first section has two subsections, the second containing two divisions :

Subsection I. Partrenaca : Abdomen sessile ; larve feeding-upon vegetable matter. This contains
the families Tenthredinide and Urocerida.
Subsection II. Exromornaca : Abdomen attached by a portion of its transverse diameter : larvae
with slightly developed trophi, and for the most part feed parasitically upon other living insects.
Division 1. Sprounirena : Abdomen with an elongated plurivalve oviduct : larvm for the
most part feeding upon other living insects. This division contains, as at present constituted,
the Cynipida, Evaniida, Ichneumortida, Chaleidida and Proctotrupida.
Division 2. Tunviirera : Extremity of the abdomen tubular, retractile, and farnixhed with
a minute sting : larve feeding upon the larvw of other hymenopterous insects, or upon
dead insects deposited by the parent with her eggs for the support of the young when
hatched. The Chrysidide.
The second section has two subsections :

Subsection I. Prapones ( Latreille) : The basal joint of the tarsi cylindrical : larve feeding upon
stored insects, or animal fluids provided by neuters. Families Crabronida, Larride, Bembecida,
Sphegida, Scoliida, Mutillida, Formicida, Vespida.

Subsection II. Mevurrera ( Latreille) : Basal joint of the posterior tarsi dilated for pollen-bearers :
larvae feed upon honey or pollen-paste deposited by the neuters. Families Andrenida, Apidae.

Tenthredinidae.

Tms family comprehends those hymenoptera usually called sawflies. The antenne are more
variable as to the number of joints, than in most of the insects of other families. The
families of the order are formed from considerations that relate to the number and form
of the joints of the antenne, and the number and form of the cells of the wings.

The insects of this family are less active than the wasps or ichneumon-flies ; they fly
sluggishly, and do not appear anxious to escape when about to be captured. The wings
fold horizontally upon the body when at rest. The female is provided with an instrument
resembling a saw, or rather a double saw, which is lodged in a fissure beneath the abdo-
men, and covered by two narrow pieces that perform the office of a scabbard. The two
blades of the saw are placed side by side, and so skilfully articulated that when withdrawn
from the scabbard they move up and down. This saw, however, has different forms in
different sawflies : it has, moreover, one advantage over the carpenter's saw, which only
cuts in one direction, and therefore is liable to pinch if it is not well set, especially when
employed in sawing green wood ; but the saw of the fly has teeth upon the sides, so that
it can move easily by cutting a free groove, It might perhaps be called a rasp or file, as its
teeth have the form of the teeth of these instruments. When in use, the saw moves in a

FAMILIES TENTHREDINIDAZ AND UROCERID, 191

grooved piece that serves as a back to keep the instrument sufficiently supported : the
edge, upon which the teeth are cut, is circular. The use of this singular instrument is to
prepare a place for the insect’s eggs : slits are made in the stems and leaves of plants, into
which the eggs are dropped. Some of the species, after depositing their eggs, girdle the
branch, which consequently dies, when it forms a suitable kind of food for the young. In
other instances, protuberances are formed which become highly charged with sap, in
consequence of which the quantity of food is greatly increased.

Cimpex vuimr ( Peck), americana ( Leach). (Plate xxvi, fig. 11.)

The generic characters of Crteex are :

Body obscurely villose : first joint of the abdomen strongly emarginate above : joints of
the antenne before the club, five ; club two-jointed, and soldered together.

The insect I have figured is the Crveex of authors ; but the antenne are properly only
three-jointed before the club, leaving out of the number the basal support, which is fixed.
The first joint is the longest, and is equal to the second and third together. If the support
is a joint, then the antenne are only four-jointed.

Description (female). Head black, shining ; antenne luteous; thorax black, margined
in front by a cirenlar brownish ridge similar to a collar : abdomen bluish black with
brownish, marked upon the sides by four ovate yellowish white spots, and anteriorly
there is a whitish space between the rings similar to a belt. The substance or mem-
brane resembles fine parchment or paper. Wings smoke-brown, semitransparent and
shining ; thighs blue-black ; tibize pale brown, and armed with blunt spurs; tarsi
yellowish or pale yellow. Length } of an inch : expanse of wing, 13 inch.

The body of this ¢enthredo or sawfly is thick and large. According to Dr. Harnis, Prof.

Peck had called this insect C. ulmi, because it inhabits the elm.

The male is more slender, and the spots are wanting on the abdomen : length about one
inch ; breadth, two inches. The larve feed upon the leaves of the elm.
The foregoing species is one of the largest of the family of the TenrHrepinip&. It does

not appear to be very common in the vicinity of Albany, inasmuch as but few are found
in our collections.

Uroceridae.

WOOD-WASPS : HORNTAILS.

Tue head of these insects is large, convex before and flat behind : antenne filiform ; wings
Jong, and overlap each other upon the back; body long and cylindrical ; rings of the
abdomen close and compact. Females are provided with an ovipositor in the form of a
slender horn projecting from the extremity of the abdomen, or from beneath it, the sheath
of which is attached to the inferior side of the abdomen by a hinge. In the male the horn
is short compared with that of the female, and is either conical or triangular.

192 ORDER HYMENOPTERA.

The sexes differ considerably both in markings and size. The borer of the female consists
of five pieces ; the two outside pieces are grooved for the reception and support of the
inner pieces, forming a hollow tube when closed together ; the inner pieces are needles,
with which the trunks of trees are pierced for the purpose of depositing the eggs. Their
young are grub-like larve which are wood-eaters, and destroy forest trees by extensive
burrowing in the green solid matter. Pines, elms, maples, buttonwood and fruit trees are
all subject to attacks of the urocerida.

Unocenvs aunicoants ( Fabricius). ( Plate xxxii, fig. 3.)

Femare : Color deep blue-black : stemmata three, situated behind the antenne in a

triangular form ; head confluently punctured ; antenne rather long, white, the base

and extremity dark brown or black. Behind the eyes there are two ova] cream-colored

spots. Thorax pubescent, punctured,and deeply impressed with a fissure running in a

circular manner from the base of one forewing to the other, and also extending down

the base of the wings, leaving an elevation with its point direeted backwards.

Abdomen cylindrical, smooth, shining, marked by a lateral oval white spot, and

terminated by a lanceform appendage. Legs black, with white joints. Length one

inch : ovipositor, nearly three-fourths of an inch; expanse of wing, nearly 2 inches.

This insect resembles the female sirex, but may be distinguished at once by its white
markings.

TREMEX COLUMBA. ( Plate xxxii, figs. 1, 2.)

Tremex ( Jurine). Stnex ( Linnwus, Drury). §. crnerus ( Drury). S. pennsyLvanicus ( Degeer).
Pigeon Tremez ( Harris).

Head and thorax yellowish brown, thick : antenna of the length of the thorax, and made
up of sixteen joints : abdomen bluish black, cylindric, ornamented by six rings, the
last interrupted at the median line of the body ; extremity yellow : ovipositor short
and stout : wings opake brown and clouded : Jegs and feet yellowish ; tibia armed
with a spur.

This insect is common in Albany county. In company with the Pimpla /unator, multi-
tudes resorted to a half-grown maple tree in the back yard of the Old State Hall for the
purpose of depositing their eggs. So completely was this tree riddled with holes when the
insects escaped after transformation, that it died in a few years, when it was found to be
perfectly mined through and through.

I have taken this species also in Maryland, so that it appears to be widely distributed.
The ovipositor is nearly half an inch in length ; the body, an inch and a half; the male
less, but it frequently happens that the female is small also : expansion of wings, two and
a quarter inches. Their wants are not confined to the maple tree : they bore or pierce the
elm and buttonwood, which are thus killed in process of time. When a tree is resorted to
for the deposition of their eggs, it furnishes the larve during every season of the year.

FAMILY ICHNEUMONID®. 193

Ichneumonidae.

Tue characters of this family, as given by Wesrwoop, are : The abdomen is attached to
the hinder extremity of the thorax, and between the base of the coxz. The anterior pair
of wings exhibit perfect cells upon their disc. The ovipositor is straight, and often exserted.
Antenne setaceous or filiform, not elbowed, and composed of more than sixteen joints,
except in a few minute adsciti. The pupa is enclosed in a cocoon. The head is small and
free : eyes lateral ; mandibles slender and bidentate ; maxillary palpi five- or six-jointed,
pendulous : wings moderate in length and size : legs formed for running. When the
ovipositor is retracted, the abdomen terminates in a point.

The larve are parasitic upon other insects.

Plate I. illustrates some of the characters of the family.

The antenne are in constant vibratory motion. The insects themselves are exceedingly
active, and exhibit a remarkable degree of instinct in depositing their eggs where their
progeny will be provided for. They are very important in the economy of nature, especial-
ly in keeping in check other species which would be highly injurious to man. They are
particularly useful in reducing the numbers of the lepidoptera, scarcely a species of which
are exempt from the attacks of ichneumon-flies. These deposit their eggs in the back of
the larva, through a puncture so minute as not to interrupt its growth and perfection ;
the larva winds itself up as usual; but in its pupa state, the eggs of the ichneumon hatch,
and the progeny feed upon it : it is consequently destroyed ; and instead of the butterfly,
there comes forth a brood of ichneumons. Before this subject was understood, the singular
fact here stated was accounted for on the supposition that certain animals were susceptible
of transformation into others.

The ichneumons have been divided into Ichnewmones genuini and adsciti : the forewings
of the former have two, of the latter, one recurrent nerve.

IcHNEUMON BREVICINCTOR ? ( Plate xxvii, fig. 10.)

Color black. Antenne with joints twenty and more : yellowish white annulus beginning

at about the ninth joint, and ending at the seventeenth from the base. Wings light

smoky brown. Scutel pale yellow : a sharp well defined ridge extends from each

anterior angle of the scutel, to the middle of the ridge surrounding the base of the
wing. Knees and tibia of the anterior feet rufous.

This individual differs from the brevicinctor described by Say, in the beginning of the
pale annulus, which, in his account, commences at the seventeenth joint, and extends only
to the twenty-first. The cellules of the wing agree with his figure, and also the opake
costal spots.

from one eye to the other. Thorax brown, marked upon the top by a trident, or a
longitudinal band terminating before in three divaricating lines. Laterally there are
two broad brown bands parallel with the first : between the wings, the middle band
divides and forms a circle, the inside of which is yellow. Abdomen compressed, sabre-
form and narrowed before. The seven rings of the abdomen are marked by semilunate
bands at their posterior margin, and succeeded by a black ring : the lateral parts of
the rings form an acute arch in the female, which enables her to flex the abdomen as
represented in fig. 4. Abdomen greatly dilated at its extremity in the female, and
terminated by a greatly elongated ovipositor. Wings transparent, and marked by a
brown patch. In the male, the abdomen is slender. Legs yellow and light brown.
The female is sometimes 1} inch long, with an ovipositor some three inches long.

The yellow bands represented as lunate, are probably too sharply arched to admit strictly

This insect formerly frequented a half-grown maple in the yard of the State House in
this city. I supposed at first that the pimpla was attracted to this tree, in consequence of
the sirex having also made it the place for depositing its eggs. The larve of both insects
were found in great numbers in different stages of growth ; but it did not appear that the
larve of the former fed upon those of the latter, for they were both in many instances full
grown and separate. In some cases the pimpla passed her ovipositor very near to a larva
of the sirex; but it could not be ascertained, after a very careful examination, that the
object of the first was to pierce the larve which infested the tree, after the manner of
ichneumon-flies. Still the habits of the family favor the view that the larve of the pimpla

FAMILIES SPHEGIDZ AND VESPID. 195

feed upon the larve of the sirex. The tree was perfectly riddled with holes and burrows,
and was undoubtedly selected on account of its sheltered position. As happens with some
other species, the females sometimes perished from inability to withdraw their ovipositor ;
and this does not seem at all strange, for they frequently succeeded in introducing it into
the wood to the depth of three inches, slender as it is.

Sphegidae.

Tue collar is dilated laterally, and extends to the base of the wings. The legs are long,
the posterior being more than twice as long as the head and thorax. The antennz are fili-
form or subsetaceous, long, and composed of elongated joints. The body is long, and the
abdomen is attached by a long peduncle. Mandibles elongate, curved, narrow, and notched
on the outside at the base : eyes entire : legs fossorial.

These insects appear like wasps, except in their pedunculated abdomen : they are
exceedingly active, restless, and difficult to capture.

SpHEX PENNSYLVANICA. (Plate xxvi, fig. 9.)

Color steel-blue and purplish : margins of the wings fading into brownish, scarcely

observable. Head transverse, short : eyes prominent; hindwings dilated behind.

Abdomen greenish stee]-blue, oval, acute, and attached to the thorax by a slender
thread. Antenne brownish : thorax and head pubescent : tarsi black.

Vespidae.

VESPA FRATERNA. ( Plate xxvi, fig. 6.)

Color brown. Surface without puncture and smooth. Antenne paler on the under side.

Wings smoke-brown, translucent. First ring of the abdomen marked with a yellow

side of the femora : tarsi luteous.

The wasp and hornet exhibit skill and patience in preparing their habitations : they
are natural paper-makers, and fabricate an article that is impervious to water.

The wasps form their habitation beneath stones, fixing it to the inferior surface. They
feed their young upon vegetable juices, and the softer parts of other inseets which they
capture. They are fond of the juices of our domestic fruits,and seem to have a preference
for the expressed juice of the apple, as they are observed to abound about cider-mill]s and
in apple-yards.

This singular insect is not uncommon in New-England and New-York in autumn. By
the roadsides, in September and October, it is seen flying slowly, as if borne down by its
long abdomen. When caught, it attempts to sting, and is capable of inflicting a slight
wound,

very narrow or thread-like base, widening in depth, but compressed laterally : ex-
tremity obliquely truncate. Legs slender ; hind ones the longest : tips of the fore-
tibie single, the others double-spined. Length of body one inch.

This is one of the most remarkable of our ichneumon-flies, and appears during the
latter part of summer and early in autumn, when it is observed busily hovering over
places where there are thickets of brambles, solidagos, asters, ete. in search of caterpillars
or other suitable objects for the deposition of its eggs. It is common in Massachusetts and

Antenne nearly as long as the body. Color honey-yellow, somewhat brownish : orbits
yellow ; wings hyaline, with two opake dots in the first cubital cellule.
This insect, though not longer than the foregoing, is rather thicker and stouter. Length
about four-fifths of an inch.

XYLOCARPA VIRGINICA. (Plate xxvii, fig. 1.)
Body thick, pubescent and hirsute; thorax globular ; abdomen ovate ; eyes brown; an-
tenn short, slightly thickened at the extremities. Thorax and adjacent part of the
abdomen clothed with yellow hair : two-thirds of the posterior part of the abdomen
black. Wings hyaline, yellowish, tipped with a dull ochre-yellow. Beneath the body
and legs hairy, black inclining to brown.

This insect attacks the dry woodwork of porticos, ceilings, ete. and completely burrows
the inside, leaving a mere shell to support the framework. It always makes its entrance on

the lower side of the railing, whence its operations are not readily detected.

C@LIOXIs ANNULARIS. ( Plate xxvii, fig. 2.)

Color black : face yellow : antenne black : thorax black ; margins lighter, and the dise

black : abdomen black ; rings annulated with yellowish white, pointed. Beneath the
body and legs, black.

ScoLtA FossILANA (Fabricius). SpHex piumrpes ( Drury).

Head pale yellow in front, black on the top and hairy : antenne black, shorter than the
thorax : neck hairy, lemon-colored : thorax black, and covered with yellow hairs :
wings dark brown, translucent : abdomen lemon-colored above, crossed by three
black lines, dark beneath : breast and arms black : legs hairy and black ; hinder
ones furnished with two remarkable long spines at the tips of the tibie : tarsi fur-
nished with strong pale yellow hairs.

ScoLiA OcTrOMACULATA.

CHAPTER XXI.

ORDER XI. LEPIDOPTERA ( Lixy evs).

GLOSSATA ( Fanatcrvs).

Tue insects that flit before us in our daily walks, and are known under the common name
of butterflies, are representatives of this order, to which also belong the numerous winged
visitants around our lamps during the summer evenings. Those which are observed flying
in the daytime, never enter our windows by night ; and neither are the moths, so common
at night, ever seen sporting by day, or flying abroad by the light of the sun.

Our first inquiry is, In what respect do the insects of this order differ from those already
described ? They have four membranous wings, clothed with minute scales : their bodies
are soft and covered with hair, and their mouth consists of a tubular filamentous organ
designed for sucking the juices of flowers, and which, when not in use, is rolled into a
compact coil; and, lastly, their metamorphosis is complete. We cannot fail to see how
widely they differ from the Co-eorrena or Ontnoprena ; although could all the species of
the different orders be spread out before us at once, we should find that they are all con-
nected by intermediate links.

The lepidoptera exist in three states : the caterpillar, the pupa, and the imago or perfect
state, in the last of which the insect propagates its kind. In the first or caterpillar state it
grows, or increases in size ; and it is during this state that it is necessitated to change or
cast off its outer integument, in order that this process may be perfected. It changes its
skin four times, and it frequently happens also that its colors and markings undergo a
succession of changes. Each insect is invariably furnished with sixteen feet. The mandibles
and maxille do not differ materially from those of the insects of other orders. The true
legs are borne by the first three segments of the body : the other legs are called false, or
sometimes prop-legs.

As it is in this state that the insect grows, it becomes necessary that it should take a
large quantity of food, which it mostly derives from the vegetable kingdom, feeding upon
roots and leaves, and sometimes upon wood. When the larva has acquired its proper size,
it ceases to eat, and proceeds to form for itself some kind of case, impervious to water, and

FAMILY PAPILIONIDE. 199

in this it undergoes a change. It is then inactive and defenceless, and appears dead ; and
as if aware that it is about to assume a condition in which it cannot protect itself, it seeks
a_secret place where it may be secure from the attacks of foes. The transformations of the
lepidoptera are of the most complete kind : in some other orders, the pupa is active ;
here it is inactive.

The Leriporrera are divided into three great sections. The first section contains the
Butterflies proper, Papritiones : their antenne are thread-like, and bear a knob. The
second contains the Spuinces, or Hawkmoths : their antenne are thick in the middle, and
often hooked at the tip. The third contains those familiarly called Moths : their antenne
are neither knobbed at the end nor thickened in the middle, but somewhat naked, tapering
or bristleform, or else feathered on each side. The order has also been otherwise divided
into two sections : the Diurnal lepidoptera, which fly by day ; and the Nocturnal, or those
which fly only during the night.

Papilionidae.

Tue distinguishing characters of this interesting family are taken from the feet, all of
which are perfect, formed for walking, and furnished with simple or bifid claws. The
antenne, which have a distinet club, have no appendage as a hook at its extremity. The
hinder wings have a slice cut out of the inner margin, for the accommodation of the body,
or else are grooved to receive it.

The larve of this family are naked, and the pupa is supported by threads of silk passed
around the middle of the body : they are both angulated and smooth in the different genera.

The butterflies of this family are among the largest and most splendid of American
insects : examples are the Papilio asterias, philenor and turnus. The family is advanta-
geously subdivided into Parmionmrs and Preripes. In the former, the anal angle of the
posterior wing is coneave or folded, and the middle longitudinal nervure of the forewing
emits four branches, while no other species have more than three ; and the palpi are short.
From their size and beauty, Liynazus gave them the name Equites.

The subfamily Preries have a gutter in the inner margin of the hindwings, for the
reception of the abdomen. The caterpillars are finely pubescent, and taper towards the
extremities. The pup or chrysalides are angular, slightly compressed, and terminate in a
point at each extremity : they are supported by a thread of silk passed around the pupa-
case. Some of the common butterflies belonging to this subfamily, the white and yellow
ones that flit about our walks, are less beautiful than those of the first subfamily, but stil]
deserve our admiration.

The genera of the family have the following characters :

In Partito, the antenna are long, but the club is not flattened : posterior wings angulated.

In Gontarrenrx, the wings angulated ; antennm short.

In Cottas : club of the antenna not compressed ; posterior wings neynded, Sud covered with scales.
In Prents, the club of the antenna is compressed ; wings naked.

In Pontta, the club is compressed : forewings trigonate, and both covered with scales.

The Corsas is the genus that contains our common sulphur-yellow butterfly bordered
with black : the Goxsarrearx and Portia are white, and our Preis is orange with a
black border.

Papiliones,
PAPILIONES ( Westwoop). EQUITES & HELICONTI ( Linx avs).

Paritio asrentas (Cramer). P. rromus ( Drury, Abbott & Smith). Butterflies.

Antenne long. Head black, marked with four yellow dots; eyes blue : body black,
marked with four rows of yellow. Wings black : beneath there is a reflection of olive
green ; nervures strong. Forewings marked by two rows of yellow spots, about eight
in each row : inner row, the spots are large and triangular, with apices directed to-
wards the insertion of the wing ; outer row, smaller and nearly round. Outer edge of
the wing spotted with pale yellow : near the anterior margin, there is a single spot
of yellow within the rows. Posterior wings tailed : upper side marked by a con-
tinuation of the yellow spots, the inner row being rounded and the outer lunate ;
between which rows, there is a row of large blue spots placed betwixt the nervures.
There is an eyelet upon the inner margin, the ring of which is orange with a black
centre : the hindwings are margined like the forewings. Beneath, the yellow spots are
converted into orange, except those of the outer row upon the forewings, and some of
the orange spots are margined with yellow : the blue spots have become lunate, and
softened into-olive-green. Expansion of wing, three to four inches.

The caterpillar is found in the month of June, feeding upon umbelliferous plants, as
the parsley and carrot. When perfect, it is smooth, and of an apple-green color ; each
segment or ring being marked by transverse alternating bands of black and yellow spots.
When first hatched, it is black, and banded across the middle : it undergoes a succession
of changes during its moulting. It has a peculiar mode of defending itself from the attack
of flies ; as when touched, it protrudes from the first segment of the body a pair of orange-
colored horns, which exhale a disagreeable odor. The pupa is of an ochre-yellow or pale

green.

FAMILY PAPILIONIDA. 201

Papitio puitenor (Fabricius). P. astrnous ( Drury).

Head, thorax and abdomen black ; the breast marked with two rows of yellowish dots :
antenne and eyes brown or brownish black. Upper sive : Forewings black with a
green lustre; apical area brownish ; outer margin marked with five spots, and edge
trimmed with black and white : hindwings polished green, silky, darker at the base ;
posterior margin marked with five white lunules ; anal angle excavated and edged
with white ; tail rounded, its angles trimmed with black and white, the crene being
white. Unper sipe : Forewings black ; apical area olive ; margin marked with five
yellowish spots ; edge black and yellowish white : hindwings highly polished, green
and lustrous, with the outer and inner margins marked with large fuscous spots sur-
rounded with a velvety black ring, with a single spot of yellowish white on the outer
side ; edge trimmed with black and yellowish white ; tail dilated. Legs and feet black.

Paritio TurNus ( Linneus). P. arctpamas (Cramer). ( Plate xxxviii, fig. 3.)

Antenne black : body black above, marked with a yellow stripe beginning at the neck,
and passing over the insertion of the wings and along the sides of the abdomen : sides
of the breast striped with yellow; palpi yellow. Upper sine: Wings yellow, marked
by five subcostal bands : the first is a marginal one, extending from the shoulder to
a yellow lunule at the anal angle; the second extends as far, but grows thinner and
terminates in a point, and the other three are abbreviated and confined to the fore-
wing : costal edge black. The outer marginal band is wide, black, and common to
both pair of wings, and is ornamented with six lunules, larger and more perfect in the
hind- than in the forewings, the first and Jast fulvous. Hindwings scollopped and
tailed : tail rather long and narrow; anal angle fulvous, edged with white, and
ornamented with three lunules, yellow, black and blue, and a ferruginous one below.
The hindwing edges are trimmed with yellow ; the forewings with white. Beneatn,
the yellow is pale; the subcostal bands are less black and velvety, and bordered with
greenish. Outer margin, the edge is black : there is a dusky yellow band, succeeded
by a broader and more dusky one, showing greenish yellow, and bounded on the
inside with a strong black line of scollops. Hindwings, the edge is yellow, succeeded
by black and yellow lunules : the black line within is bordered with blue. Expanse
of wing four inches. Length from the head to the extremity of the tail, 2} inches.

This is one of our common butterflies, and resembles the Macnaon of Europe, but its
markings and form are more like those of the Popatiaivs. Its larve are not known as
injurious to the cultivated vegetables.

Hleliconiidae.

Gexus DANAUS.
The generic characters of the Daxaus, as drawn up by Mr. Sar, are as follows :

‘ Anterior feet spurious in both sexes : antenn@ terminated by a club; palpi distant, sub-

‘cylindric, short : inferior wings rounded, not forming a groove for the reception of
‘the abdomen : nails of the tarsi simple.’

DaNavus PLEXIPrUS. ( Plate xxxvili, fig. 1.)
Head and body black, marked with two rows of white dots : sides also marked with many
white dots : five posterior rings of the abdomen edged with white, with two rows of
dots beneath. Wings entire, fulvous red varying in depth in different individuals :
nervures and ¢cost# black; lateral and posterior margins trimmed with a black
border, and two rows of white spots with a black and white edge : apical area black,
and marked with elongate and subquadrate spots of the ground-color of the wings,
with smaller spots of white extending along the costa. Brxearn, paler : hind- paler
than the forewings ; in other respects, the markings are not dissimilar to those of the
upper surface. Eyes and legs steel-blue : tarsi velvet-black. Expanse of wing, four

and a quarter inches.
Common, and widely distributed. The larve are harmless, feeding on useless plants, as
the asclepias, etc. : they are annulated with white; the pupa is green, and dotted with

golden spots.

LiMENITIS DISSIPPUS. ( Plate xlvii, figs. 1, 2.)
Ground-color of the wings precisely the same as in the Danaus plexippus. In the apical
area, a somewhat triangular spot of black extends from the apex to the outer angle,
within which there are four oblong spots of the color of the wing, and a smal] one at
the junction with the marginal border : this black spot is marked with three white
spots, and sometimes four in the row; the lower one is a mere dot. Between these
white spots and the apex, there is an elongate white lunule, or an elongate pointed
spot. Beneath the costa, there is sometimes a white spot towards the base of the wing.
The hindwing is marked by a narrow black belt, extending from near the middle of
the costa, across the wing to the anal angle. Beneatn, paler : upon the forewing
there are two subcostal bluish white spots, and a dash of white on the costa near the
black triangular spot. In the apical area, the fulvous spots are five in number, and
more distinct than those above. Hindwings, the black belt is bordered on its basal side
with three or more bluish white spots placed between the nervures. The border in
both pair of wings is trimmed with black, upon which the inner row of spots forms

FAMILY HELICONTID®. 203

a distinct lunule, succeeded on the outside by interrupted curved blue lines : edge
trimmed with black and white.

Head and body black : the back of the head is marked with four white spots, the first
pair placed at the base of the antenne. Antenne black, tipped with rufous : palpi
black, striped with white on the outside. Eyes blue, with a white spot posteriorly.
Each side of the thorax is marked with three large white spots : cox# white; the
ventral portion of five rings, white, and an abbreviated lateral white line. Legs black :
tarsi of the forelegs striped with white in front. Expanse of wing varies from two
and a half to three inches.

This species is found accompanying the D. plerippus in the vicinity of Albany, and is
usually regarded as a mere variety of the same ; but the many differences in the markings,
taken in connection with the constancy in size of the numerous individuals I have exa-
mined, leave no doubt of its distinet character.

LIMENITIS URSULA. ( Plate xxxiii, figs. 1 & 2.)
Color black above, black and brownish beneath : antennz black ; knob rather slender :
eyes brown : head black. Behind the antenne there are two white triangular spots,
and a white line beneath and outside of each eye. Thorax and abdomen black above :
sides of the former marked with three white spots; on the latter, the edges of the
rings of the venter white, and sides marked with a wide white stripe. Outside palpi
white : upperside of the imperfect forefeet white. Forewings subfalcate ; outer margin
slightly sinuate ; nervures of the wings with four branches : posterior wings slightly
angulated, without tail, subtrigonal. Upper spr, velvety black : forewings marked
with submarginal bluish and rather obsolete lunules ; apical area marked with two
white triangular spots ; edge trimmed with white and black : hindwings marked
with two rows of pale blue quadrangular spots, the third upon the inner row from
the anal angle being a lunate spot. Outside of these there are two rows of sublunate
spots, the outer white, the inner blue ; the former are placed upon the edge. Benearu,
the apical area is brownish, and marked with white spots, which become obsolete as
they extend towards the outer angle. Base of the wing bluish in some lights, and
marked with two brown and four blue subcostal spots : the blue spots are small, and
stand two and two; the margin is trimmed with two rows of lunules, and the edge
with white and black. Behind the disk is brownish, similar to the apical area, and
the base is marked with a cluster of rufous and blue spots. The margin inside has
five rufous spots surrounded with black, and two rows of lunules parallel with the
edge, which is trimmed with white and black.
This species is found as far south as Georgia, yet does not appear to be commen any
where : it feeds on the gooseberry leaf and wild cherry, and is figured in Asporr and
Smitn’s Lepidoptera.

Consas rutconier, (Godart). Clouded-sulphur Butterfly. ( Plate xxxv, figs. 1,2,4& 9.)

Partito pPAL@NO? ( Linnwus), Cotas rvropome (Swainson).

Mare : Antenne ferruginous; knob blackish above, ferruginous beneath, tipped with
ferruginous or rosy color ; palpi yellow, clothed with long hairs, greenish at base :
eyes brown. Head blackish above ; tips of the hairs often reddish. Trunk and abdo-
men blackish above, or rather greenish ; beneath, yellow. Wings yellow, broadly
bordered with black. Anterior wings above marked with a centra) dismond-shaped
black spot, which is matched by a faint yellowish spot upon the posterior wing :
beneath yellow, with a greenish tinge, especially beneath the black border of the.
forewings. Posterior wings of a deeper tint of sulphur-yellow than the anterior, and
marked with two brownish spots each : the first is near the middle of the wing, and
coalesces with a smaller spot towards the anterior margin, and both are ornamented
in the centre with a spangle of silver; the other, a reddish oblong brown spot, is
placed directly midway upon the anterior margin of the wing, pointing to the coa- .
lescing central spots. Wings ciliate : ciliw rosy red.

Femare : The colors of the wings are much like those of the male. The border is rather
paler, and shows six spots of the ground-color of the wings, placed two and two :
four of the spots are nearer the apical angle. The posterior wings show obsoletely the
marks placed beneath : the black border is fainter and narrower than in the male.
Beneath, the anterior wings scarcely differ from those of the male ; the posterior are
paler, and, if any thing, show a faint rosy tint, with three or four small dots. Ex-
panse of wing, about two inches.

The females differ as to depth of coloring : some are nearly as yellow as the male; in
others, the yellow is pale and whitish. The caterpillar is described as pubescent, green,
with yellow lines and black dots.

Powtia ovenacea ( Harris). Potherb Pontia.

Knob of the antenn# flattened, black, and tipped with ferruginous ; setaceous part, white
beneath ; above black, with the lower margin of the rings white. Head white, with a
black spot upon the back of it. Thorax and body black, with the ends of many hairs
and scales white ; the sides of the abdomen are striped with white. Anterior wings

FAMILY HELICONIID. 205

white, and tips and base dusky, which color extends outward along the nervures.
Posterior wings white above, slightly yellowish green beneath.

Dr. Harais has given a minute description of the eggs and caterpillar of this species,
from which it appears that the female lays its yellowish eggs upon the leaves of cabbages,
radishes or turnips, about the first of June ; that they are hatched in about a week, and
that the caterpillar attains its full size in three weeks : it measures an inch and a half in
length, is of a pale green color, and feeds indiscriminately upon any part of the leaf,
perforating it in many places. The pupa state lasts about eleven days.

This butterfly, as may be supposed from its habits above described, is injurious to
garden plants. There is no other way to save cabbages, ete. when attacked by the cater-
pillar, than to crush it under foot. It is common, but less so than the Co/ias. Neither inflict
very extensive injury upon the farmer ; and if the birds could have their own way so far
as to inhabit the trees about the garden without molestation, they would always keep these
minor evils in check : the indviduals of any species of insect would never increase to an
extent such as to call the husbandman or gardener from his other duties.

The Pontia oleracea has a resemblance to species of the Genus Aprerrx : in all these,
however, the antenne are shorter, not flattened, but clavate, and the wings are angulated ;
and finally the individuals are all larger than the P. oleracea.

PIeRIs NICIPPE? ( Plate xxxv, fig. 7.)

Head and body black above, but crossed at the back of the head and thorax with yel-
lowish ; beneath, yellow and orange along the sides. Antenne rather short : knob
yellowish. Wings yellow or orange: border wide, black, and edged with orange about
the middle : below the anterior edge there is a short black line ; the anterior border
rather greenish. Beneath yellow, with a few splashes of red particularly on the hind-
wings. Forewings, the outer border is yellow, while the basal part is a deeper yellow:
the outer edge of the forewing is dotted with brown ; and the fore-edge of the hind-
wing shows many sharp dark lines, but frequently obscure.

Though this species does not agree in every particular of coloring with the nicippe, it is
not so far removed as to admit much doubt of its being the same. It has a wide range, ©
being found in Pennsylvania and Virginia as well as in New-York ; but here it is far from
being common.

Some of the figures have been colored of a deeper orange than the specimens ordinarily
exhibit : indeed some individuals scarcely partake of this color at all, bearing mostly
upon yellow.

Fig. 7, upper side ; 6, lower side.

Nymphalidae.

Tux distinguishing characteristics of this family are found in the forelegs, the antenna,
the posterior groove of the hindwings, and the peculiar manner in which the pupa is sus-
pended. The anterior legs are defective, being short and unfitted for walking ; the antenn»
have a distinct club, it may be compressed or somewhat prolonged below, but never hooked
at the tip : the two hind pair of legs are furnished with bifid claws, the hinder tibia with a
single pair of spurs ; and the posterior wings receive and protect the abdomen in a groove.
The larve bear spines or else tubercles, and are cylindric ; the pupa is angulated, and
suspended by the tail.

This family embraces the beautiful species that have received the common names of red
and white admirals, pointed-ladies, fritterlaries, etc. Their flight is strong, and more than
makes up for the imperfection of their feet.

The genera may be known by the following characters :

The VANess™ have angulated wings ; antennm rather abruptly clavate ; eyes pubescent.

The Cyntat have rather rounded wings, or only subangulated : in other respects, they closely re-
semble the vanessm.

In the Liwenrres, the wings are more or less rounded ; the antenna are straight ; the club gradually
thickens : eyes pubescent.

In the Hrrrparcuts, the club of the antenna gradually thickens, and is more or less curved.

The Anaynwes have the antennw rather abruptly clavate, and club short ; eyes naked ; wings broad,
and the head large.

Nymphalides.
Vanessa antiora. Willow Butterfly. ( Plate vi, figs. 5, 6, 7.)

Papritio ANTIOPA ( Linnswus, Donovan).

Above the medium size. Wings angulated : upper sides deep purplish brown ; surface
appearing like velvet, bordered with a broad wavy belt of black, in whieh there are
angular violet-blue spots : outer margins cream-colored, sprinkled with dots arranged
somewhat in lines; the salient angles of the border more distinctly marked. The
anterior margin of the primary wings has cream-colored spots beyond the middle,
towards the outer edge : the underside of the wings darker brown, terminating in
the scollopped mottled gray border, in which there is a row of darker angular spots.
The secondary wings are prolonged slightly into tails.

The caterpillar is black, with a series of spots along the back, and each joint armed with
spines. It consumes the leaves of the poplar, willow, etc., but injures more especially the

FAMILY NYMPHALID. 207

elm, from the branches of which it often hangs in clusters ; and when once stripped of
its foliage by the larve of this species, which are more numerous some years than others,
the tree rarely recovers.

The pupa is suspended by its tail from the underside of a stone or rail, and is pointed
and armed with a double row of spines upon its ventral surface.

The antiope or willow butterfly survives the winter : it seeks a warm secluded place, and
hence in the spring it appears early. The young butterfly comes forth from the chrysalis
state in July ; and in August a second brood of caterpillars appear, which pass through
their changes before winter.

In consideration of the extensive injury these caterpillars inflict upon some of our best
kinds of shade trees, it is very desirable that they should be destroyed, by shaking them
from the limbs on which they congregate, and crushing them under the foot. It is only by
taking this advantage of its larval state, that the increase of the species can be effectually
checked.

VANESSA INTERROGATIONIS. Semicolon Butterfly ( Harris). ( Plate xxxv, fig. 5.)

Head and body brown, hairy. Anterior wings angulated and reddish or dark reddish
orange, with their borders broadly shaded with black and obscurely marked with
reddish spots, of which the longest is situated at the superior and outer angle, and
dotted or marked within with black : middle spotted with seven angular black spots.
Posterior wings all black except their bases, but the black is not sufficient to conceal
rows of reddish spots : posterior and lateral margin edged with a black line, within
which there is a reddish white line extending and spreading over the short tails.
Underside of both pairs of wings the color is rust-red or marbled : the border of the
hindwing is also ornamented with faint bluish green lunate spots. The centre has the
pale silvery comma. Expansion of wing, 24 — 2? inches.

The caterpillar is spinous, brownish and variegated with yellow and brown, and lives
upon the hop.

There seems to be some variety in the markings of this butterfly, though the general
pattern is much the same.

Vanessa pRoGNE ( Fabricius). Progne Butterfly.

Antenne brown : knob dark brown, tipped with lighter ; outside spotted with black and
white ; beneath light brown. Head with a black spot at the base of the palpi. Body
brown, light beneath and black above. Wings angulated, brown, and spotted with
black. Anterior wines : Outer margin black, marked near the centre with five
round spots placed in a right angle : above and near the margin there is an oblong

larger spot than either of the five; beyond, a dusky patch with the apex black.
Postreaion wines, mostly dusky black, but brownish towards the base ; tails and
margins powdered with reddish white : beneath grayish, mottled reddish or orange,
and with obscure spots of lighter and darker color partaking more or less of brown.
Hindwings marked with a silvery ¢ opening outwards.

This species furnishes considerable variation in the markings, as well as in expansion
of wings. It is a common species, generally smaller than the red admiral and comma but-
terfly.

Dr. Hanns regards this species and V. argentea, described by the late Rev. W. Kiney
in the Fewna Boreali Americana, as the same.

Vanessa comma ( Harris).

Dr. Hannis has recently described an American comma butterfly, which had been
regarded as identical with the European : although closely resembling the latter, the
hinder wings are not so deeply indented, which feature may serve to distinguish the two.
For description, see Haxnis’s Injurious Insects, 2d edition, p. 241.

Vanessa potycutornos? Comma Butterfly.

Aytenion wines, dusky orange, darker at base, marked with four large subquadrate spots
upon the disk, of which three are in a line,and the other is placed below the middle
spot of the three : costal margin with three large abbreviated fasciw, the middle one
the largest, the apical one smallest and whiter : outer margin dusky, and marked
with an irregular pale line. Postexion wives have a large black or dark brown
costal spot : outer margin marked with crescents, which are not sufficiently distinct
to warrant insertion in this deseription, owing to injury ; a slender pale line is visible
running parallel with the edge. Beneath the wings are clouded, the basal portion much
the darkest ; the higher portion, or broad band is striated transversely by numerous
darker interrupted lines. In the middle of the posterior wing there is a silvery curved
line.

The individual above described differs about as much from the English polychloros, as
our Vanessa atalanta or Cynthie cardui from theirs. The most important point not made
out, relates to the bluish lunules upon the outer margin ; but on applying our polych/oros
to the English figure, I find it fits in length and breadth, and also the angulated and scol-
lopped edges. There is a close correspondence in the patterns above and beneath, and the
general resemblance is so near that it will not be safe to treat our species as distinet from
the English.

Vanessa urtic“? Tortoise-shell Butterfly. ( Plate xlvi, figs. 8, 9, 10.)

Papriiio urtic® ( Linnaeus).

Upper sides of both pair of wings bright red-orange, dark at the base, and covered with
long olive-brown hairs. Costal margin of the forewings marked with three large black
subquadrate spots : between these spots, pale orange, with a whitish figure towards the
apex, but within the border. Under the three black spots mentioned, there are three
quadrangular spots upon the disk : the one nearest the base, rectangular and largest,
and bordered on the outer edge with yellowish ; above which are the two smaller
spots. Exterior margin of both pair of wings black, and ornamented all around with
blue lunules : beneath, the basal half of the hind-pair is nearly black ; outside of
which there is a belt of brown marked transversely by darker lines, and then the
blackish border ornamented with obscure or black lunules. On the forewings there is
a large pale orange patch, corresponding to the reddish orange markings above.

Antenn® : rings marked with white and brown; knob brown, terminated with pale
orange ; palpi gray, from an intermixture of white and brown hairs. Expanse of
wing, 1} —3 inches.

I am unable to say whether this is a common species in this State, or not : it has been
taken in the vicinity of Albany this season (1853), and I believe frequently. It resembles
Say’s V. furcellata, obtained in the Northwest Territory ; but in the latter there are two
subquadrate yellow and reddish spots near the costa upon the black ground, and the broad
belt is orange, bearing upon the costa a large black spot.

Vanessa ATALANTA (Fabricius, Curtis, Stephens). Papilio atalanta (Stephens).

Base of the anterior wings rich brown ; of the apical half, brownish black with a tinge of
blue, in which there is a series of white spots arranged in a curved line, the two
largest spots separated by the two smallest. Between the broad orange fasciz and the
series of white spots, there is a large white spot upon the costa. The orange fascia
crosses the wing, but does not quit the posterior angle : the scollopped edges are
trimmed with white. Posterior wing, two-thirds of the basal part rich velvety brown,
ornamented with a broad border similar in color to the fascia of the forewing, and
dotted through its middle with black, besides the two confluent blue spots of the
anal angle. Brnearn, the forewings are black ; and between the middle orange band
and base, there are red and blue lines : apex ashy brown. The hindwings are brown,
black and grayish, traversed transversely by black narrow interrupted wavy bands :
beneath the orange belt the color is ashen, marked with black angular lines. On the
costal margin there is an ashen patch, with a darker middle.

Cyxtia canput. Vanessa cardwi (Godart). » (Plate xlvi, figs. 1, 2.)

Asrenion wine : Disk reddish orange, extending near the base ; apical part nearly black,
marked with quadrangular spots, the two smallest placed just to the right of the other
two : the large costal spot within the four spots spoken of, is divided into three parts
by the nervures : margin and edges trimmed with white brown, and an interrupted
line which reaches the costa between the white spots and apex. Postrmion wines
reddish orange, their inner margin covered with long brown hair : upon the disk of
orange there are four regular round black spots, an imperfectly formed bar within,
with two rows of black spots without, placed with long diameters at right angles to
each other ; the edge is trimmed with white. The hindwing is orange, spotted all over
with black spots : the costal margin, which is connected under the forewings, is
white. Brexearn, the coloring is brighter on the forewings, but the pattern is much
the same as above. The hindwings are ornamented with four distinct eyes, the two
smallest in the middle ; the centre is black ; then a partial ray of blue, then of black,
then a distinct one of buff margined with black. Towards the outer angle there is
often a fifth much smaller eye, arranged on a line with the others. The whole of the
portion within the eyes,and the nerves, are all white, with numerous Jarge and small
white and light brown angulated spots and bars.

Cyxtata nuntrera ( Kirby).

Parizio canput vineinrensts (Drury). P. rove (Cramer). Vanessa nvxtera (Dale, Stephens).

Edges of the wings rounded, or only subangulated. Disk of both pair of wings orange red,
brown at base, and darker at the apex; disk broken by black irregular transverse
bars connected by delicate lines : apical part marked with four silvery white spots ;
the two smallest are outside of the larger, and the costal one is divided by the black
nervure into two parts. There is also a large subquadrangular spot resting on the
costa : outer margin trimmed with parallel scollops of white, brown and orange. On
the posterior wing the ornaments consist of two black circles with blue centres, be-
tween which are two black spots. The margin does not differ much from that of the
forewing, except that the scollops take the form of lunate spots : upon the anal angle,
these spots have blue dises. Brexeatn, there is much greater complexity as well as
beauty of coloring. The principal and characteristic ornaments are the eyes on the
apical angle of the forewings, and two large eyes surrounded with black upon the
hindwings : the disk is a patch of white composed of mealy seollopped lines. The
margin below resembles that above.

The caterpillar is said by Drury to be green, with black rings around the body, and
feeds on balsam or lady’s-jewels.

FAMILY NYMPHALID. 211

Limenitis ARTHEMIS. .Vymphalis arthemis (Drury). (Plate xliii, figs. 2 - 9.)

Wings black, marked by a broad white band common to both pair, reaching very nearly
to the margins : apical portion marked with three white spots, to which a fourth is
sometimes added. Beneath, the basal portion is black, perhaps greenish, and orna-
mented with a cluster of brown spots and bluish green bars situated near the base :
at the apex there are three white spots. Posterior wings beneath are marked with six
or seven brown spots outside of the white band : margin trimmed with white, black
and blue. The last-mentioned spots are in two parallel lines, and bear the form some-
what of lunules.

The anterior pair of feet are white before : abdomen black, and the venter has a yellow
stripe on the specimen before me.

This species seems to have a wide range ; being found as far north as Lake Winnepec,
and south inte Virginia.

ARGYNNIS APHRODITE.

Stipe of the antenne long, buff-brown ; knob black. Head and body buff, with black upon
the thorax and upper side of the abdomen. Color of the wings bright buff-yellow or
fulvous : forewings spotted and banded with black, and both pair darker at base as
well as hairy. In front there are six or seven black subcostal bands : the four from
the base are connected with a zigzag band which extends across the wing ; or they
may be regarded as a connected series of lunules, having in front of their concavities
a row of six round black spots, beyond which is a regular row of seven lunules
smaller than the former : margin trimmed and edged with two black lines, which
are dilated where they cross a neryure. Hindwings marked with distant rows of lu-
nules, between which there is a row of roundish spots : they are trimmed and edged
like the forewings. Benearu paler, and the subcostal bands are more distinct : there
is a double row of lunules, with three spots between. At the apex, the black spots
and lunules of the upper sides are replaced by silvery ones. Hindwings, base deeper
colored than the wide margins, and ornamented with three parallel rows of bright
silvery spots, and several more which cluster at the base : among the rows, there are
small silvery spots scattered about without order : margin trimmed with a plain
brown band edged with black. The silvery spots are surrounded with a black ring
wholly or in part; and there is a straight line also on the forewings, between the
third and fourth subeostal bands. Expanse of wing, 2} inches.

This species si very common in the western part of Massachusetts and Eastern New-

York.

212 ORDER LEPIDOPTERA.

AMGYNNIS IDRALIA,

Antenne brown, tipped with rufous. Forewings a buff brown : costa and margin black,
marked by five subcostal bands, besides the straight band which forms a delta with
the fourth : apex black, marked with four white elongated subcostal spots : disk
marked by a row of five round spots, besides which there are two lunules in reversed
position with respect to each other, and two rather quadrangular spots; the outer
margin is trimmed with black, bearing a row of eight or nine white spots. Hindwings
dark or very dark brown, but lighter at the base, and marked with two rows of large
white spots. Bexsatu, the forewings present much the same pattern, except that the
white border spots are more distinctly in the form of short arrowheads bordered with
black. Hindwings very uniformly dark brown, and spotted with large white spots :
there are three parallel rows, and the basal cluster might be called a fourth; the
shoulders have also a white stripe running along the edge of the wing. Expanse of
wing, four inches.

This species is fur less common in the vicinity of Albany than the aphrodite.

Mecit®a prueron. ( Plate xliii, figs. 4, 7.)

Stipe of the antenne ringed with black and white : knob, base fulvous, middle black,
tip gray : palpi, eyes and feet rufous. Head black, with a ring of white around the
eyes, und a row of white spots passing around the head just behind the antenn».
Thorax and upper side of the abdomen black, with a few white dots along the top,
and two rows along the sides. Beneath the abdomen is marked with a rufous red
series of largish spots on each side, and the venter with a row of yellowish white
spots. Uprrer sive : Wings black : outer margins ornamented with four rows of
spots ; the outer row rufous, resting on the nervures, and divided ; the three inner,
yellowish white ; the innermost row short : beyond the rows there are two or three
dashes of red, parallel with the costa. Hind- marked like the forewings, except the
short row of spots is wanting. Berxerarn, the surface of both pairs is marked with
four rows of yellow spots between two of brown, except the inner brown row of the
forewing is replaced by two large brown subcostal spots : on the hindwings, there is

a cluster of brown and yellow spots at the base. It should be noted that the yellow
spots of the outer row are all lunules opening outwards. Expanse of wing, 2 inches.
This season (1853) this butterfly is quite common, while in former years it was scarce.

MELITAA PHAROS. ( Plate xliii, figs. 5 & 6.)

Head, body and wings black, marked with numerous red and yellow spots. Hindwings
marked with six orange-colored spots extending across the wing, the concavities
turned towards the base of the wing. Outside of these spots, there is a row of six

ocellate spots with black centres : these ocelli stand between the nervures. Near the
base there is a lunule, with a round spot in its concavity. Underside reddish clay-
colored, mottled and clouded. Forewing the red is deeper, and the outer angle or
apex has a dark triangular space dotted with red : outer margin clouded with red-
dish of different hues. Spread of wing, about one and a half inches.

This beautiful species is less common here than the preceding.

Hipparchiides,
HIPPARCHIIDES (Wesrwoop). SATYRIDES ( Borspvuvat).

Tue palpi of this subfamily are three-jointed and elongated, and their antenne thickened
very gradually at the tips. The insects are not robust, but rather feeble in flight. Their
colors, though frequently beautiful, belong rather to the neutral tints : they are brown
and yellow, with ocelli for ornaments. The larve feed upon the grasses during the night
season : their bodies are widest in the middle : some of them undergo their transforma-
tions in the earth, and others suspend themselves by their tails.

Hipparcuia ALOPE. ( Plate xxxiii, figs. 5, 6.)
Brown ; paler beneath. Antenne slender and arcuate : knob a mere dilatation of the
upper end ; stipe annulated with white. Upper stipe : Forewings marked with a
broad luteous band, or rather oblong spot placed upon the outer half of the wing,
and ornamented with two eyelets with a black iris and bluish pupil. Hindwings more
distinctly crenate than the forewings, and marked towards the posterior margin with
a single small eyelet with a black iris and blue pupil. Benerarn, the eyelets are
rather more distinct than above. Wings barred transversely by darker lines : posterior
are marked by six small eyelets arranged in two lines, three in each ; the largest in
the middle, and each surrounded with a perfect brown ring outside of the black iris.
The margins of the wings are traversed by black and brown lines running parallel
with the edge, which is densely ciliate. Legs ashen. Common.

Hirparcuia NEPHELE. Clouded Hipparchia. ( Plate xxxiii, figs. 3, 4.)

Color brown above and beneath, but paler beneath. Antenne annulated with white ; knob
slender. Upper sive is marked with an obsolete but broad submarginal band, in
which there are two eyelets with a clouded white or bluish white pupil, and a black

iris with a very indistinct brown ring. The posterior wings are crenate, and marked
with a minute or obsolete black spot. Unprr srpr, the belt of the anterior wings is
much more distinct, the eyelets bright, and the outer ring of brown plain : margin

of the wing traversed with two or three lines parallel to the edge. Outer half of the
hindwing paler, and marked with six small eyelets, which form three rows, the largest

eyelet being in the middle ;: the anal angles divaricate, leaving a wide triangular
space.

This species was first described, I believe, by the Rev. Mr. Krany in the Founa Boreali
Americane.

Lycenidae.
LYCANIDS (Leacn). POLYOMMATID AE (Swanysoy).

Tue insects of this family are small and weak, but finely and delicately colored and
marked. The forelegs are fitted for walking, and the last joint of the palpi is small and
naked. The caterpillar has a small head nearly concealed under the first ring, and secures
itself, when about to undergo transformation, by the hindfeet and a loop about the body.
The chrysalis is flat on the underside ; its ends are round : the imago six-footed. Social,
and often collected into groups upon sweet-scented flowers.

THECLA ACIS. ( Plate xliii, figs. 2, 3.)

Po.yommatvs ( Latreille & Godart). Paprr1o acts (Drury). P. 1xron ( Fabricius),

Superior wings immaculate and dark brown above, paler beneath ; posterior, bicaudate ;
the two inner the longest, and immediately above are two red spots, and two more |
upon the anal angle. Unper srpe, the wings are lead-colored, crossed by a narrow
white and black line running parallel to the external edges ; the posterior are crossed
by an indented irregular line ; the four long reddish spots stand above four black

ones. :

Tuecta moment ( Harris).

Anterior or primary wings dusky brown on their upper sides, tinted with bluish gray ;
and, in the males, they are also marked with an oval spot on the front edge. The
posterior wings are slenderly tailed, but, unlike those of the acis, they are tipped with
white ; and the margin posteriorly is also marked by a row of pale blue spots, among
which is a crescent of orange marked in the centre with a black dot. It is a little
larger also than the acis ; expanding about an inch and a tenth, while the acis is only
about an inch.

In its caterpillar state, the T. humu/i feeds upon the heads of the hop, as is implied by
its specific name ; its color is green, and its skin is downy. Described by Hannas in his
work on inseets injurious to vegetation, p. 235, 2d edition.

FAMILY HESPERIIDZ. 215

Hesperiidae.
SKIPPERS.

Heap large, with large and prominent eyes : bodies short and thick ; feelers short, hairy,
and ends square or angular. Antenne short and distant from each other, ending in a
knob prolonged and bent into a hook, and pointed. Legs six, and the four hindshanks
furnished with two pairs of spurs.

Larva : Head large : body tapering from a cylindric middle, spineless, and generally
naked. Solitary, concealed within a rolled Jeaf; their transformations taking place
in envelopes of leaves and fragments of straws bound together by a few silken threads.
Chrysalids taper from one end, and are rounded : they make imperfect cocoons, which
are formed of rolled leaves and threads.

Evpamus tityrus. Tityrus Skipper. { Plate xxxviii, figs. 4, 5.)

Antenne brown : eyes brown, with a white spot beneath. Uprrr spe: Head, body and
wings brown, lighter at base. The middle is crossed with a wide yellow band, nar-
rowing towards the posterior angle : between it and the apex there are two yellow
dots or spots. Hindwings tailed, rounded upon their anal angle : beneath they are
marked by a large oval and central white spot; the edges trimmed with yellow or
yellowish brown. Expanse of wings, 2-2} inches. The larva is pale green, and
striped transversely with darker green and dotted : head and neck red and tubercu-
lated (fig. e) ; fig. f, pupa.

The ¢ityrus inhabits the locust-tree, making its habitation of the leaves drawn and kept
together by threads of silk, which serve also for its transformation : it feeds on the leaves,
and sometimes nearly strips the tree of foliage.

This season (1853), which has furnished many other rare insects, this skipper has not
been common.

PAMPHILA PHYLEUS.

Uprer stipe : Thorax and abdomen yellowish olive. Superior wings tawny yellow. mar-
gined with a black toothed border : three dark brown spots traverse the wing, the
outer corner one coalescing with the border. Inferior wings yellow, subangulated :
margin with a dark brown border, sharply indented : anal angle truncate. Bexeatu,
the wings are paler, marked with brown somewhat triangular and lined spots : one
elongated spot near the shoulders. Expansion of wing, 1} inches. The caterpillar
feeds upon the panic and butfalo grasses.

This is a very common butterfly in Western Massachusetts, in August, in meadows.

216 ORDER LEPIDOPTERA.

Cunysoruaxus ruceas. Copper Butterfly. ® ( Plate xvi, fig. 4.)

Color copper-red above. Forewings margined with black : area of the dise marked with
six or seven oblong black spots. Hindwings, dise and base dusky black ; posterior
margin red, trimmed with about six black spots, and furnished with short tails. Br-
neatu : Forewings, the dise is orange or cupreous orange, spotted with black, and
margined with ash. Hindwings, base and dise ash, spotted or dotted with black, and
bordered with faint copper-red.

Common at midsummer in the vicinity of Albany and Western Massachusetts.

Hesrenta reckrus (Kirby). Peck’s Hesperia. ( Plate xxxii, fig. 8.)

Color brown, paler beneath. Both pair of wings widely bordered with brown ; area of the

dises bright yellow, with a band of brown extending outwards from the base, ciliate ;

ciliw fuscous. Brnearn, the area of the dises is occupied with yellow patches, ir-

regular in form ; that upon the hindwing is usually double. The body is clothed with
long yellowish brown hairs, especially upon the breast.

There is considerable diversity in the form or shape of the yellow patches on the dises :
in some, the whole area of the disc of the forewings is yellow. It is very probable, how-
ever, that this may prove a species distinct from the peckius. The latter is common in fields
in Western Massachusetts and Eastern New-York, in July.

Sphingidae.

HAWKMOTHS.

Tis family of Lerroprera has received the special attention of naturalists from Liyxaeus
down to the present time. They fly with great strength and vigor, with a bird-like motion
of their wings ; and are capable of sustaining their flight for a long time, and of poising
themselves in the air like the hummingbird while sucking the nectar of flowers. The
tongue is coiled compactly when not in use, and frequently exceeds the body in length.
The antenne are prismatic, presenting in a cross section the segment of a circle on one
side, while others are formed by two curved lines meeting in such a way as to make an
edge on the opposite side : it often terminates in a feather-like tuft. The labial palpi are
broad and compressed ; but the labrum and mandibles are rudimentary, as they are not
required for taking food.

The larve are naked, cylindrical, and supplied with sixteen feet, and ordinarily a horn
is placed on the eleventh segment of the body : they are commonly ornamented with
oblique stripes on the sides. They usually descend into the earth when their transformation

is about to take place. The pupa too will be found naked, and sometimes an appendage
exists in the form of a bent hook, like the handle of a pitcher : this is a distinct case,
and contains the tongue. Where this organ is short, the appendage is absent. The wings
are generally covered with scales ; but in some cases they are transparent, as in the Srsia,
from the absence of scales.

Many of the larve, when not engaged in feeding, fix themselves by the hindlegs, and,
elevating their bodies at a considerable angle, remain stiffly fixed in that position for
hours : in color and position, they then resemble a broken twig of the bush upon which
they have been feeding (See Plate xxxvi, fig. a).

The hummingbird moths, or sphinges, fiy in the early morning, or in the dusk of the
evening, when they visit the garden or the wild flowers of hedges, flitting rapidly from
one blossom to another, and poising themselves with the utmost ease by the rapid motion
of their wings, which are long and pointed, but of unequal expanse, the forewing being
the longest. Their bodies are thick and robust, and frequently pointed behind ; or else
they terminate in a fan-like tail, as in the Srsrm.

There is a diversity in habit in this family, as in all others : while some fly swift, others
are slow and sluggish in their flight ; and while some prefer the twilight of the morning
or evening, others take the wing only during the day. The Smerinthus has a slow heavy
flight, and flies only in the night ; and it is doubtful whether it takes food in the imago
state, as its tongue is too short to be useful for that purpose. When at rest, the wings are
horizontal or a little inclined ; and the posterior have an apparatus consisting of a setiform
process at its base, which passes through a hook to the anterior, for the purpose of re-
gulating the extent of their motion.

This family contains but few genera, which may be indicated by observing the following
characters :

1. SmerinTuvs : Wings more or less angulated ; flight heavy : tongue very short : antenne in the
males biciliate beneath.

2. Spuinx : Tongue long : wings entire, acute : labial palpi robust : antennz not clavate.

8. DerLepaiia : Antenne clavate.

4, Sesta : Wings partially clear and transparent : abdomen terminates in a short flat brush.

5. Puitamprius : Wings subfalcate ; inner margin sinuous.

6. Cu@rocampa : Antenne short, arcuated, terminating in a long slender hook : margins of the
wings sinuate ; hind-angle angulated.

7. CeraTocAMpA : Antennz in the males with distinct joints, doubly bipectinated : wings entire.
Larva with horns upon the shoulders.

Sruixx sxowres ( Drury). ( Plate xl, fig. 1.)
Antenne white within and brown on the outside, and tapering to a hooked bristleform
point. Uvrrea stipe, fuscous and clouded, but traversed transversely by two or three
sets of black crinkled lines, the outer one forked at the outer angle of the anterior
wing, having the shape of the letter U ; dise of the wing dirty yellow, and marked
with a white spot. Posterior wings, outer half brown; base gray : the brown part is
traversed obliquely by a curved gray line. Head and neck dark brown; thorax and
abdomen gray : the rings marked on each side of the median line by narrow black
bars. Usora stor : Breast white; abdomen white, marked by four reddish spots
placed along the middle ; posterior wings dark gray brown, but gray upon the corners
and abdominal edges; cili# white and brown ( Dauny, Plate xxix, fig. 4).

Spuixx ocromacuLatus. ( Plate xxxvili, fig. 2.)
Color black. Forewings marked with two oblong yellow spots; hindwings with white
spots : thorax has also yellow spots. Rings on the upper side of the abdomen white ;
extremity black.
This insect makes its appearance very early, and feeds upon the tender leaves of the
grape-vine : its larva goes into the ground, where its transformations are completed.

SpuixX CARoLinus. ( Plate xiii, fig. 10.)
Color gray, grayish brown. Forewings marked with narrow zigzag bands, and with white
spots, one at the base,and a small central one : hindwings banded. Abdomen marked
with two rows of orange-yellow spots, five in each row. Expanse of wing from three

to four inches.

Spanx convotyuti. Potato Hawkmoth.
This species has eight transverse bands upon the abdomen : the ground-color is red-
dish. Its posterior wings are marked with oblique black bands. The larva feeds upon the

sweet-potato vine.

Spuixx cmronantut. Fringetree Moth.
This moth has three yellowish round spots on each side of the abdomen. The larva is
greenish yellow, and is marked obliquely with black and yellow on the sides.

Spurnx vitis. Vine Hawkmoth.
Wings margined with red, and marked with yellow stripes : two interrupted stripes on
the back, and several transverse on the abdomen.

FAMILY SPHINGID2. 219

Spumsx ——? ( Plate xlv, fig. 9.)

Forewings subfaleate, and sinuate upon the anal margin. Color of body and wings buff of
various shades. Antenne strongly and doubly pectinated. Forewings banded ; inner
margin marked with a quadrate brown spot. Beneath banded : middle of the hind-
wing marked transversely with a light ferruginous band.

This species I obtained at Williamstown ( Massachusetts). It is closely allied to the

Philampelus in the form of the forewing : the abdomen, however, is terminated by a short

brush as represented in the figure. I have been unable to refer it to a described species.

SpHINX CINEREA.

Wings greatly elongated and narrow. Color gray, and the forewings dashed with black
lines : there is a black spot at the base. Hindwings gray, and banded with black ; the
bands are broad, transverse, and towards the outer margin. Margin of the abdomen
marked with alternate bands of black and white : abdomen more pointed than in the
5-maculatus. Back gray, without spots, but marked with a longitudinal line along the
middle.

SPHINX QUINQUEMACULATUS.

Forewings gray : area of the disc darker than the margin. Hindwings gray, and marked
with four black zigzag lines, the outer broadest ; the next is a zigzag line : the basal
is scarcely more than a spot. Abdomen broad at the base, upon which there are black
and white bands : margins ornamented with four or five yellow spots, alternating
with black bands and square spots. Expanse of wing, 3 — 34 inches.

The pupa-case is brown, and furnished with a long curved handle which encloses the
tongue. This is the common potato-moth, the larva of which descends into the earth to
transform, where it forms a rounded smooth chamber with its sides. The larva is green,
and marked with oblique whitish stripes upon the body : it is also furnished with a horn
placed posteriorly.

PHILAMPELUS SATELLITIA. (Plate xlv, fig. 5.)

Color above light, and marked with spots of dark olive. Head light olive, with two spots
of light olive on the front of the thorax ; below which is a large angular spot of dark
olive, which extends to the base of the forewing, and forms an abbreviated band.
Back of the thorax there is a transverse band, which connects itself with a dark hairy
olive spot upon the base of the hindwings. The basal half of the margin of the fore-
wings light olive, clouded, and.extending itself to near the posterior margin, where
it meets a darker submarginal band, the Jatter extending to the apex, and banded

inwardly by wavy lines of olive and flesh-color : outer half olive, but marked with
transverse abbreviated lines of darker, Apical area has a patch of flesh-color, but
branched so as to include a costal spot of olive : posterior margin olive, and the olive
marked with wavy bands. Hindwings marked with a row of submarginal olive spots.
The conspicuous dark olive spot near the body has been noticed ; there are also al-
ternating abbreviated transverse lines of olive and flesh-color near the inner margin.
Beneath buff or fuseous, traversed by narrow bands or lines ; posterior margin darker.
Expanse of wing about four inches.

This is not an uncommon species in New-York and Western Massachusetts. The larve
feed upn the grapevine, and hence Dr. Hannis has given the generic name Philempelus,
‘T love the vine.’ They also feed upon the Ampelopsis.

The larva may be known by the recurved slender horn of the back when immature,
but which is lost at the last moulting, leaving a smooth eyelike spot. Color pale green :
sides marked with oval cream-colored spots. The head is retractile, which makes the insect
appear shortened and blunt before.

When mature, the insects are three inches in length : they are great feeders, and, when
in numbers, injure vines in proportion to the leaves consumed.

Pwitamretus —— (Harris). Sphinz pampinatriz? ( Plate xliv, fig. 2.)
Color olive. Head olive, from which proceeds divaricating bands along the angles of the
thorax, lighter between the forks. Antenne light buff. Forewings banded : at the
base olive, marked with a costal spot of flesh-color : middle band broad and flesh-
color, with a dot of olive ; external band olive, wide, subbanded or marked with a
stripe of flesh ; edge brownish. Hindwings flesh-colored, with an olive spot or im-
perfect band upon the anal angle. Bexearn, buff : basal part of the forewings
slightly ferruginous ; the apical area buff; margin light olive. Hindwings, base light
buff; outer half darker buff, marked with a wavy line parallel to the edge ; edge
lighter. Body beneath buff : thorax colored like the base of the hindwings, and the
abdomen like the outer half, without spots.

Aegeridae.
(See Plate xxvi, figs. 1, 8.)

Tue peculiarities of the insects of this family are, the translucency of thelr wings, elon-
gute form of body, and the absence or rather deficiency of scaly covering when compared
with the Srm~erms. They bear some resemblance to the Hymexorreaa : thelr antenne
are simple, and often terminated by a small pencil of hairs. The insects are interesting,
from the faet that they are highly injurious to trees, especially fruit trees. They are fleshy
grubs of a cylindrical shape (fig. 4), with brown heads and strong jaws ; but unlike many
of the larve of this order of insects, they have no caudal horn. They have the ordinary
true six legs, eight ventral feet, and two feet at the extremity of the abdomen.

The different species feed upon different kinds of trees ; some upon the currant, moun-
tain ash, ete. The most destructive one is the “£geria eritiosa of Say, which preys upon
the peach-tree. The egg is deposited upon the bark near the root, and, when hatched, the
young penetrates to the wood, when it either continues its course into the wood, or burrows
between the wood and bark : usually, however, it proceeds into the soft wood, sometimes
just below the surface of the soil, at other times above. In either case, such is the extent
of the injury inflicted, if allowed to maintain possession, that the tree is killed. Probably
the peach-trees in this country have suffered more from the £geria, than from all other
insects put together.

AXceRia EXITIOSA. ( Plate xxvi, figs. 1 - 5.)
Fig. 5, female ; 1, male; 4, larva; 2 & 3, cocoon and pupa.

Color steel-blue. Wings of the male transparent, and bordered behind with steel-blue :
palpi, feelers, edges of the collar, and shoulders yellow ; smaller than the female.
Feaace, steel-blue : wings steel-blue ; hindwings transparent : middle of the abdo-
men marked with an orange-colored ring or belt. Expanse of wing, 1} inch.

Mr. Hanais remarks that the egeria does not confine its attacks to the peach-tree, but
may be found also on the cherry, its larve being developed in the black knotty branches
of the tree. It does not always locate itself at the base of the trunk of the peach-tree, but
trequently bores into the limbs, in which case much less injury is done to the whole tree.
The infested tree may be diseovered by the presence of the dust and cuttings which the
larve: throw out around the roots; but it is often necessary to remove the surface soil, in
order to detect their presence.

The mode that is most successfully pursued for extirpating these insects, is to cut them
out with the knife, avoiding the sound parts of the tree as much as possible. A wire thrust
into the burrows may destroy the larve, without cutting the tree.

FAMILY AGERIDA. 223

The cocoon is constructed partly out of the castings of the larve, which, by means of
gum and silk, is formed into 2 common oval shell surrounding the pupa : these may be
destroyed at once.

To protect a tree, Dr. Harris long ago recommended the use of sheathing paper, secured
by strings and matting to the neck of the tree after removing the earth. This paper should
be cut in strips eight or nine inches wide, and fixed below the soil by means of mortar and
fresh loam. The application requires renewal every spring ; but whatever means may be
adopted, careful examination during the months of June and July should not be neglected.
Wounds that may be made in the removal of living bark and wood, should be covered
with grafting wax, or something to protect the surface from water.

The currant-bush is injured by the geria tipuliformis, which is not a native of this
country, but is of European origin. The eggs are laid near the buds, and, when hatched,
the larve penetrate the bark and wood, and even into the pith : the stems become brittle ;
but, before this, they show marks of disease by yielding an inferior fruit.

Dr. Harris describes another insect allied to the Hernia, the Trochilium denudatum
( Harris) : the color is brown; the edges of the collar and of the abdominal rings, the
shins, the feet, and the underside of the antenne are yellowish ; the forewings opake, and
the hindwings transparent. It attacks the ash : this tree, especially the english mountain
ash, when planted for ornamental purposes, seems to be quite as liable to the attacks of
these borers, as the peach ; and hence it requires the same attention and treatment.

GLAvcoPIs PHOLUS. ( Plate x], fig. 3.)

Guavcopis (Fabricius). Sparx pHowvs ( Drury).
Antenne black, and thickest in the middle. Upper side black : basal half of the wings
orange. Beneath the color is paler, but after the same pattern.

The larva feeds on lichens growing upon stones, and hence is more common in bleak
stony places.

CHAPTER XXII,

ORDER XI. LEPIDOPTERA ( Continued ).

BOMBYCIDES.
PHAL-EN® ( Lixnaevs). MOTHS.

Tie antenna of moths, as has already been observed, tapers from the base to the apex : it
may be simple, or plumed like a feather ; but the organ differs much according to sex,
the pectinated antenna being more strongly marked in the males, who are also provided
with a sucking tube which takes the place of a tongue, and is rolled up very compactly,
being sometimes very long, in other cases very short. The palpi grow from the upper lip,
curve upwards, and cover the face, the tongue being coiled up between them.

The larve of the moths differ much among themselves. The number of legs is usually
sixteen, but some have only ten, and some are obscure and incomplete. They differ too as
to their clothing, some being very hairy, others nearly or quite destitute of hairs; some
are smooth, others warty or spinous : some go into the earth to transform, others remain
above ground.

In treating this division of the Lerrvorrena, I shall follow very nearly the arrangement
of Dr. Hanns. By Lixyavs, the moths or spinners were divided into eight groups, viz :
1, Attaci ; 2, Bombyces ; 3, Noctua ; 4, Geometra ; 5, Tortrices ; 6, Pyralides ; 7, Tinea ;
8, Alucita.

Lithosiidae.

Tue moths of this family have slender bodies, are never very large, and their wings when
at rest lie flat upon their bodies. The antenne are bristleform and rather long, and but
slightly feathered in some of the genera ; in others, in the males, there is a double row of
short hairs on the under side. The tongue is distinct, but only moderately long. The back
is not woolly, and the thorax is not crested. The wings are often beautifully spotted or

FAMILIES LITHOSIIDA AND ARCTIIDA. 225

speckled upon a white or yellow ground. The larve dwell in stony places, and many of
them feed upon the lichens that grow on the stones : some feed upon grass.

Detoreia BELLA. Beautiful Deiopeia. ( Plate xlvi, fig. 5.)
Color of the forewings yellow, traversed by five or six white bands : bands dotted in row
with black. Posterior wings scarlet, though pale, and bordered irregularly with dusky
black or dark brown. Body white : thorax spotted with black. Expanse of wing,
nearly 2 inches, or 1} inch.
It is found in Albany county in midsummer. ,

Arctiidae.

Tue feelers and tongue mostly short and thick. Antenne doubly feathered : feathering
narrow on the inner or upper side, and less distinct in females. Wings inclined : thorax
thick. Both the caterpillars and moths hairy or downy, especially the thorax and head of
the moths. They are more or less white,and ornamented with black or dark-colored spots
upon a white or buff-colored ground. They are nocturnal, or fly only by night.

The caterpillars move rapidly, and are covered with hairs that spread out in tufts from
warts. They make, in clefts of rocks and sheltered places, rough cocoons of the hair of
their own bodies, interwoven with some fibres of silk. The chrysalis is smooth, and its
joints movable.

Sprtosoma Acr#=A. Saltmarsh Caterpillar. ( Plate xli, figs. 2 - 5.)
Spriosoma (Stephens). Patna (Bompyx) Acrea (Drury). Bompyx acrra ( Fabricius).
ARCTIA PSEUDERMINEA ( Peck).

Mate, upper side : Head and thorax white on the upper side; lower side yellow buff,
embracing the wings, abdomen and thorax. Forewings cream-colored, marked and
margined with many black spots : hindwings buff, and marked with six somewhat
angular spots ; the lower side is deeper colored. Antenne and eyes black.

Mate, Jower side, buff-colored. Forewings margined with five or six elongate black spots,
the posterior margin dotted with black : the other black spots upon the dise show
through the wing, and appear to belong to the upper side. Hindwings marked with
seven or eight spots somewhat lunate in form ; one of which is quite prominently so,
near the middle and outer margin of the wing, but stands in reverse position to one
upon the margin. Abdomen of a buff upon the upper and inferior sides; the sides
being marked with a white line, which also extends to the tip of the abdomen : upper
side ornamented with a row of black spots, and two rows that stand upon the margin
of the white lateral line, and another line upon the lower and central part or face of

the abdomen.
[ Acricuttugat Report — Vot. v.] 29

Fesate : Head, thorax, wings, and lower abdomen white or faint cream-color : upper
part of the abdomen, and lower part of the thorax except extremity, buff. Wings
spotted with black ; hindwings prominently marked with a black lunate spot near
the centre. Abdomen marked with black spots as In the male.

The caterpillars appear in the salt marshes in the vicinity of Boston, according to Mr.
Hanus, towards the end of June, and grow rapidly till the first of August, when they
attain their size, which is about 1] inch long, and clothed with hairs. They then retreat to
the uplands, in order to undergo their transformation : for this end, they seek a sheltered
place, and construct of silk and the hairs of their bodies a coarse cocoon, and soon change
to a chrysalid ; in which state, in the latitude of Boston, they continue until the next year,
when they are transformed into moths. The caterpillar is clothed with long tufts of hairs,
which grow from warts, either brown or black, or of various shades of brown : the skin
is yellow, though shaded at the sides with black ; the back is also marked with a blackish
line’.

This insect not only inhabits the coast or saltmarshes, but is found abundantly inland

in Berkshire county, and in Albany and vicinity. It is destructive of the grass of salt-

meadows ; and when it retreats from them to undergo its transformation, it devours the
more valuable vegetables, as corn, beans,and garden plants. The remedy proposed by Mr.

Haxnis is to mow the marshes early, while the caterpillar is immature ; it is thereby

destroyed.

SriLosoMA ARGE. ( Plate xli, fig. 3.)

Antenn# doubly pectinated : teeth short on the upper side. Color at the base whitish, or
cream-colored ; extremities dark brown.

Motu : Upper side cream-colored, somewhat variable in its shades. Collar marked by two
black lines ; upper side of the thorax by three black lines, widely separated. Anterior
wings cream-colored,and marked with many triangular spots : the inner margin has a
wide line running parallel with it ; the other spots are small acute triangles : margin
beneath pale fuscous. Posterior wings marked mostly on the posterior margin by four
black spots, sometimes only dusky. Posterior margins of both pair ciliated ; and just
within this border there is a fuscous or reddish line. Inferior surface dusky cream-
colored,and marked like the superior, except that the anterior margin of the anterior
wings is bordered with fuscous. Neck covered with vermilion red hairs; throat black.
The cream-colored abdomen is ornamented with five rows of black spots; two upon
the sides, and one upon the centre of the back. Femora red anteriorly ; joints and
tibize black in front ; tarsi black. Expansion of wing, nearly two inches, but variable.

FAMILY ARCTIID£, 227

The flight and habits of this moth are much the same as those of the S. acr@a, which it
also resembles in figure, but is smaller. The caterpillar is brown, with five pale longitudi-
nal lines, and covered with long hairs growing from fulvous tubercles : it feeds upon
plantain, leaves of indian corn, peas, etc., and is frequently quite injurious.

The moth appears in the vicinity of Albany, and in Western Massachusetts, in June ;
perhaps earlier. While they are said to be occasionally injurious to corn in the Southern
States, the insect is too rare here to give rise to much apprehension.

Evcu&teEs EGLE. ( Plate xli, fig. 11.)
PHALANA EG@LE (Drury), Spriosoma EGLE ( Westwood). Evcuares* ( Harris).

Antenne slightly pectinated. Head, thorax, underside of the body, and legs gray. Wings
thin, bluish gray, paler on the front edge, immature. Neck cream-colored : top of the
abdomen indian yellow, and marked with three rows of black spots, one on the top
and two on the sides, each row consisting of about seven spots. Unper sive : Tongue
spiral, a little longer than the head : abdomen pale yellow ; wings gray; margins
entire.

Carerritiar : Head, body and legs black, and marked with a light-colored line on each
side, hairy ; hairs grow in short tufts from warts. The first and second rings support
four long pencils or tufts, which bend over the head.

The caterpillars feed upon the milkweed (Asclepias syriaca), and may be regarded as
harmless : they are social, and, when feeding, their heads are turned to the edge of the
leaf.

CattimorrHa vircuncuta ( Kirby). ( Plate xlvii, fig. 5.)
Color black. Head and thorax striped with black and orange. Forewings, ramifications of
the nervures orange : hindwings orange marked with black, roundish. Akdomen
orange above, marked along the middle with triangular black spots : beneath paler.
Lateral portions of the abdominal rings marked by a double row of angular spots
placed close together : venter pale orange. . Expansion of wing, 1} inch.
This is a common species in the vicinity of Albany : found in meadows in August.
Figured in Ricuarpson’s Fauna Boreali Americune.

CALLIMORPHA PARTHENICE. ( Plate xlvii, fig. 6.)

Body beneath black. Head and thorax pale orange, marked with five oblong spots, two
before and three behind. Forewings black and orange : the orange follows mostly the
nerves, but transverse bands are sent off so as to form many triangular spots. Hind-
wings red, marl:ed with large black patches surrounded by narrow luteous rings ;
beneath paler and more dusky. Beneath, the rings of the abdomen are black, and the

extremity pale and pointed. On the top there is a row of spots, the apices
of which point towards the thorax. Expanse of wing, 2] - 24 inches.
The markings of the forewings are quite similar to those of the virguncu/a found in the
vicinity of Albany.

Cattimonrna epiments. Phalena epimenis (Drury). ( Plate xlili, fig. 10.)

Urrean sive, black. “Anterior wings ornamented with a single large yellow spot just out-

side the middle of the wings. Posterior wing ornamented with a large single red spot,

whose outer margin is nearly parallel with the posterior margin of the wing. Uxcrs

sipe, black, and similar to the upper, except two additional straw-colored spots be-
tween the large ones and shoulders.” Duuny, Vol. ili, p. 40; pl. 29, f. 3.

Cautimonrna ruyiirma ( Latreille). ( Plate xlili, fig. 8.)
PuaLana puyiirma & nomnyx ( Drury). Hypercampa (Stephens).

Urrer store : Anterior wings black. Cilie cream-colored. The margin next to the body
marked with cream-color : the outer half is marked with a B. The posterior wings
are scarlet, marked with four angular spots, and margined with black. The under
side is like the upper, but with fainter colors.

The caterpillar is marked with smal] diamond-shaped yellow spots upon its back and
sides, emitting fascicles of hairs : it feeds on corn, peas and wheat, and breeds most of the
summer.

Spriosoma wars (Stephens). Phalena ( Drury). ( Plate xli, fig. 9.)

Antenne black and pectinated. Head and body light yellowish brown. The thorax has

three black longitudinal marks, and several spots upon the abdomen. Anterior wings

black, marked with broad ochre-yellow lines : ciliw light yellowish brown. Posterior

wings light yellowish or ochre-brown, marked with a faint black spot on each, and

having a broad irregular border of a dusky black running along the external edges,

but very narrow in the middle : wings entire. Under side marked like the upper, but
paler. ( Westwoop : Illustrations of Drury, Vol. i, pp. 15, 16.)

Sprtosoma cunea ( Drury). ( Plate xlvii, fig. 7.)

“Antenne pectinated, black : no tongue : head white; back and abdomen ash-color.

Anterior wings white : spots numerous, of many forms, and of a sooty black : exter-

nal margin marked with five spots ; those nearest the tips, triangular. Posterior wings

white, with dark spot near the external edge, and faintly marked near the external
angle. Expansion of wing, one inch and five lines.” Drury.

This moth has not fallen under my notice either in the vicinity of Albany, or in Western

Massachusetts.

FAMILY ARCTIID. 229

ArctiA IsABELLA (Harris). Isabella Tiger-moth.

Antenne filiform, tawny yellow. Thorax tawny and brownish. Abdomen tawny, deeper
color beneath, and marked with three rows of black spots, about six or seven in each
row running upon the back and middle of the sides. Forewings tawny, and marked
with a few black scattering spots. Hindwings nearly transparent, slightly tawny, and
marked with six tawny spots. Legs black or dark brown.

I have found this moth in Williamstown, though it does not seem to be very common,
as only a few individuals are taken by the different collectors here. The caterpillar, how-
ever, is common, and is frequently seen travelling aeross our paths in autumn, always
moving as if in great haste. It is brown, and thickly clothed with hairs of a uniform
length, stiffand short : the hairs are black on the first four and two last rings. On being
taken up or touched, it rolls itself up. It feeds upon sundry kinds of herbs, but it is not
to be ranked among the decidedly injurious insects.

ArctrA virernica. White Miller, or Virginia Ermine-moth.

Color white. Forewings marked with a black point, and two black dots on the hindwings.
Abdomen marked with three rows of black dots, one on the top of the head, the two
others upon the sides, between which there is a yellow stripe. Thighs of the forelegs
ochre-yellow.

Arctia (var. of vrrernica).

The wings of this moth are entirely white, except that the hindwings have two black
dots upon the underside, and one at the base of the forewings. The abdomen is ochreous,
with the three rows of black dots, and a broad belt of ochre-yellow between.

The .4rctia figured on Plate xlv, fig. 4, may also be a variety of the virginica, but its
abdomen is white.

ArcTiA virco. American Tiger-moth. ( Plate xli, figs. 3 & 4.)

Wings deflexed : color pink-red, with two central triangular black spots ; spots above
and below, angular, oblong : near the posterior margin, a thick black mark extending
nearly its whole length ; outer margin bordered with a fine black line. There are
twelve black angular spots in each wing, the smallest upon the upper and outer angle.
Secondaries yellow and red : in the male, the black dots large, and arranged some-
what in the form of a triangle. The spots near the anterior margin have quite a small
one between them. The female has about nine black spots on the posterior and middle
half of the wing.

CarerritLaR brown, with four yellow or yellowish white and green stripes, interrupted
with paler brown, upon each bulging ring, and ornamented with a double row of
round dots ; below which, upon the sides, there springs a heavy brush of brown hairs
arranged in a thick pencil.

This insect feeds upon corn and a variety of other plants, as the plantain, peas, ete. :
when the corn is young, its feeding is injurious to the plant. —

Liparidae.

Aytexx® doubly pectinate, short, and bent. In the males, the teeth are longer than those
of the females, which are also narrow. Feelers hairy, like those of the erctiide, but
longer. Tongue short and invisible. Fraaves : Body thick, and furnished with only
rudiments of wings. Mares : Body slender; wings broad.

These singular moths are hairy like the arctiens ; but the female, being wingless, is
always found upon or near the cocoon from which she has escaped, and hovering around
her is the male or mate. When at rest, the forelegs are extended considerably forward ;
while the wings, sloping but little, are folded together over the back.

Some of the females of this family are provided with wings, though only imperfectly,
as they fly but sluggishly. The males are diurnal, and fly during the day in search of the
females.

The caterpillars are also peculiar, being half naked ; and the covering of the remaining
portion consists of long tufts of hairs growing from the sides of the body, and from warts,
of which there are some six or eight. Some have four or five thick tufts of hair upon the _
back, cut short and even; and from the extremities, or from the first ring, two beautiful
tufts of long hair project forward in the form of feelers.

These caterpillars are called tussocks, from the tufts upon their backs. They resort to
trees and vines of different kinds, and feed upon their leaves. Their cocoons are oval, thin,
and made of silk interwoven with the hair of their bodies. They are more or less injurious
to vegetation : indeed some of them inflict fatal injuries upon fruit-trees.

Oxcy1a Leveosticma. Pale Emperor Moth. (Plate xxxvii, figs. 1 & a, b,c : female.)

Antenne of the males brown upon two-thirds of the posterior part, whitish upon their
anterior margin. The markings are two transverse waved lines and one white towards
the base, with four thick dashes towards the outer angle : there is also a white an-
gular spot upon the middle of the posterior margin. Secondaries brown and black
upon the nervures, and margined with a lighter shade of brown.

Femace wingless, or with only rudiments of wings : color ash or brownish ash ; abdomen
large.

Carrarit.ar cream-colored, longitudinally banded with brown, and black upon the back.
Head red, with two large jointed pencil-shaped tults of hairs upon the posterior part

of the head, and one of equal length upon the posterior extremity. It is also orna-
mented with four equal cut brushes of hair upon its back, situated upon the anterior
half of the body, and is fringed along its abdomen and extremities with long hairs.
This caterpillar is common here in the spring, and feeds upon the leaves of the oak and
the horse-chestnut.

Saturniadae.

BOMBYCID_& (Stephens).

Tue caterpillars of this family are naked, cylindrical, and, as Mr. Harris describes them,
have hunched backs. They are furnished with warts, which are often bristled, and may
be either simple or compound in form. They construct a cocoon of silk, which is placed
within a single leaf, or else within several drawn together so as to form a partial protection
against the outside ; or sometimes they are fastened longitudinally to a twig by gummy
matter. They are unlike the pupa-cases of the Pariioyes, which are angular, spinous, and
suspended by a short thread with the head downwards.

The antenne of the moths are strongly and doubly pectinated, especially in the males,
and their bodies are thickly covered with a dense mat of hairs or wool. The tongue is
rarely visible. The wings, when the moth is at rest, are extended horizontally so as to
exhibit both pair : they are also destitute of hooks. The wings are commonly ornamented
by one or more conspicuous eyelike spots.

The insects shun the broad daylight : their eggs are large and numerous : their cocoons
are composed of a strong silk, which might possibly be converted to use ; and they offer
this advantage, that they feed on the leaves of the common forest-trees, and hence there
would be no danger of the loss of silkworms from an accidental scarcity of food, occa-
sioned by untimely frosts, ete.

The Satrurniap& may not be regarded as specially injurious to the farmer, or to forest
or fruit-trees : at least the injury they produce is small, compared with that inflicted by
cankerworms, leaf-rollers, ete. which are far less conspicuous in themselves.

The males of this family, according to Mr. Sternens, fly well, and go abroad in the after
part of the day. The females fly sluggishly, probably from the weight of the abdomen.
The wings are gray or drab, usually of a neutral tint; and the ornaments consist of ocel-
late spots, some of which exhibit the brightest of colors.

Saturnia mara. Corn Emperor Moth. ( Plate xxxix, figs. 2,3, & c,d, e.)

Wings black, with a broad band of pale yellow traversing the middle, translucent and
thin. Forewings marked by a yellow lunar spot near the margin of the inner black part

of the base of the wings : lunar spot also upon the middle of the yellow of the pos-

terlor wings; the wide black border margined interiorly with dark gray. Antenne
brown, pectinated in both sexes. Front of the thorax yellow, hairy ; bairs of a rust-
color posteriorly. Abdomen black, marked with three reddish rings, and the male
has the last ring of the same color.

The male and female have a very close resemblance : the male, however, is a little
smaller, and has two tufts of reddish hair upon the lateral parts of the thorax ; while the
females are marked with forked reddish lines upon the anterior wings, which terminate
in the yellow stripe across the thorax. Pupa-case black.

The caterpillars of this species are of two kinds, or rather are marked after two different
patterns. The head and feet are red, and each ring is ornamented with three pair of red-
dish compound spines, These spines sting sharply ; and though not at all common, they
have been found in an oak and hickory grove three miles south of the city of Albany,
together with the larva or cocoon of the insect. The figures were copied from Auporr &
Saurn’s Insects of Georgia.

Urrer stp, mace : Color indian yellow. The anterior wings are marked with two oblique
wavy lines towards the hinder margin, a zigzag line near the same, and several spots
arranged so as to form the letters A H, all of a purplish red color. Posterior wings
hairy and purplish, red at the base : on the posterior margin there is also a curved
band of the same color; and within this band is a curved black line, and on the
middle of the wing a black spot with a bluish centre, upon which there is a silver-
white line or dash pointing to the inner and posterior angle.

Femace : Anterior wings purplish brown or cream-color when faded, and marked in the
middle with a brownish spot. Thorax and legs purple brown. Abdomen same as male.

Greatest expanse of wing about three and a half inches.

The caterpillar measures two and a half inches when fully grown : its color is pea-
green, marked on the sides by a brown stripe edged with white, the stripe beginning at
the fourth ring. The surface is covered with stinging prickles, standing and spreading in
clusters and terminating in black.

The moth is hatched in July from the pupa, in which state it has remained through the
winter.

These caterpillars feed upon the leaves of the elm, poplar, dogwood and sassafras, and
also upon clover and indian corn. During a part of their lives they are social, and, when
they move, they march in regular files.

Arracus tuna. Green Emperor Moth. ( Plate xxiv, fig. 1.)
Actras (Leach). Paatmna Luna ( Linnzeus.)

Head small, white, encircled with a faint brown and narrow ring. Antenne brown, pecti-
nated. Thorax pale yellow and woolly, ornamented with a stripe in front continuous
with that upon the front margin of the wings. Wings pea-green, marked with eyelike
spots near the middle : outer margin bordered with purple brown. Posterior wings
prolonged into long narrow tails bending outwards. Body covered with a white wool-
ly substance, and rather close-pressed : legs purple brown. Expansion of wing about
five inches.

The caterpillar is fully grown about the first of August. It is of a bluish green color

[wrongly colored in the figure], striped with yellow on the sides, and transversely also

between the rings : rings marked by about six small reddish or purple warts. Length,

when in motion, nearly three inches ; but when at rest, only about two inches.

In feeding, it prefers the leaf of the hickory, though it may be kept upon the leaves of
several of our forest-trees. In North-Carolina it feeds upon the leaves of the liquidambar
or sweet gum, as also upon the persimmon.

N. B. In some of the figures I have observed that the body and abdomen are colored a
light brown, the thorax and neck being yellowish white or cream-color in the animal.

The male expands nearly five inches, and the female six inches.
The species is said to breed twice in the year : its caterpillar feeds upon the buttonwood
( Platanus occidentalis, Lixxxus), oak, and sweetgum. The caterpillar is greenish, tawny
green or orange green ; body spinous, hairy, and the second and third segments armed
with two pair of short rugose horns.
Almost every season, I have seen a few specimens of the Dryocampa : it is, however,
a rare insect in the vicinity of Albany, or in the western part of Massachusetts. 7

Mr. Harnis has removed the foregoing species from the Genus Cenatocampa, where he
had placed it in his Catalogue of the Insects of Massachusetts ; and refers it, though with
some hesitation, to the Genus Dryocampa*.

Lasiocampadae,

Tue caterpillars of this family are hatched from eggs glued into a gammy substance
insoluble in water : the substance entirely surrounds a small limb, forming thus a thick
protuberance, in which are contained some three or four hundred eggs. These eggs are
hatched as early as April or the beginning of May, or with the development of the leaves.
They immediately spin from their mouths a tent like a spider’s web, into which they retire
at midday and evening, and where they remain until the sun has warmed the air the next
morning.

The caterpillars are sparingly hairy, and free from warts ; they are social in their habits,
and congregate by hundreds in their impervious tents. They travel with considerable speed.

The moths are woolly, and their wings are without hooks ; but the anterior edge of the
hindwings is turned up, and laps upon the forewings ; and when at rest, they are inclined
and cover the back of the insect like a steep roof. The under wings project beyond the
upper, when closed upon the body. The moth flies only by night.

The /asiocampians are among the most injurious insects the farmer has to contend with :
they are, however, easily managed, and only require attention and industry when they first

appear in April or May. Their habits enable us to take advantage of them, and destroy
whole broods at once : numbers of them retire in a body to their tents at stated times of
the day, when both houses and inhabitants may be destroyed by one sweep with a pole
properly armed.

Cuistocampa AMERICANA ( Harris}. American Tent Caterpillar. (Plate xlv, fig. 1.)
( Plate xlvii, fig. 6 : eggs.)

Color rust-brown or reddish brown, variegated with gray especially on the middle and
base of the forewings. Anterior wings crossed obliquely by two dingy white parallel
lines : margin ciliate and whitish. Hindwings without lines or spots : a portion of
the costal margin whitish. Beneath darker.

The caterpillar has a black head, and its back is marked by a whitish Jine. On each
side of this white line there is a broad longitudinal stripe, formed by a yellowish ground
marked by crinkled lines coalescing below, so as to make a row of spots upon each ring
of the body, in the middle of which is a small blue spot : below is a narrow wavy yellow
line ; and lower still, the sides are variegated with black and yellow lines. Underside of
tbe hody dusky. The eleventh ring bears a small blackish hairy wart, and the body is
sparingly clothed with hairs.

The caterpillars come to maturity and begin to leave the trees by the middle of June ;
or, in other words, they then break up their encampment, and each seeks some suitable
crevice in which to make its cocoon.

This is one of the most injurious caterpillars known to infest gardens and orchards. As
the eggs are deposited upon the trees, they are enabled, as soon as hatched, to begin their
depredations upon the young and tender leaves. We cannot, as in some other instances,
prevent the ascent of the young caterpillars up the trees, for they are already there ; but
we may, after the fall of the leaves, search for the eggs, which are deposited in quite
conspicuous rings around the twigs, and remove them by hand, whereby an entire brood
will be totally extirpated ; and if a general attention be given at this period, an orchard
need never suffer from the operations of this insect.

The damage that trees occasionally suffer by neglect is very great ; for the tree, when
deprived of its leaves, will die, or else must put forth a new crop, an alternative that
seems always to produce a state of great exhaustion, and from which the tree scarcely ever
entirely recovers. From this cause, when a tree has been neglected for several seasons, and
consequently has become stocked with these devourers, it barely sustains itself, and soon
shows marks of old age and premature decay : many limbs actually die the first season,
and the whole tree wears the appearance of poverty and distress.

The direct means to be instituted for ridding an orchard of these destructive visitors,
must be such as can act upon the whole brood while sheltered in their tents. These means

are various. Some farmers blow and burn off the tents, and al) their inhabitants, with a
small charge of gunpowder : others twist off the tents with a forked stick, or a pole with
a stiff brush fastened to its end,and trample the dislodged insects under foot ; others still
employ a swab charged with whale-oll soap, a very little of which article will kill many
of the insects, and compel others to disperse. Whichever of these means is resorted to, it
must be put in requisition either late in the day, or at noon, or early in the morning before
the inseets go out to feed. It is also advisable to begin early in the season, with the first
appearance of the caterpillars : their tents are then small, and a whole community may
be destroyed with the greatest ease.

To eradicate completely the tent caterpillar, it will be necessary to give attention to the
wild cherrytrees that are scattered over the farm and by the sides of fences : the cherry,
it will be seen, is a favorite tree with this insect, and scarcely passes a season with entire
freedom from it.

It will be observed, that if the foregoing remarks are true, the farmer has no need of
receipts to heal the ravages of these insects ; for, to ensure freedom from their attacks, he
has only to examine his trees after the fall of the leaves in autumn, for the rings of eggs
on the small branches, which may be removed by the hand or a knife ; or if this has been
neglected, then search for the tents of the young caterpillars when the buds begin to open
in the spring.

As the caterpillar grows, the tent is enlarged by the construction of an additional web
over and around the first, enclosing thereby a space large enough to meet the demands
arising from increased size; and so it continues to add successively new webs over the
old, which have become filthy, and unfit and unhealthy as dwelling-places, though a few
of the weak and more indolent remain still within them.

ArTAcus POLYPHEMUs. ( Plate xliv, fig. 1.)
Color dull ochre-yellow, somewhat clouded with black. Wings ornamented with an eyelike
spot : adjoining their margins there are two paralle] belts, the outer one reddish and
the inner black. Outer angle of the superior wings marked with a black spot, divided
by a reddish white line. Eyelike spots round outer narrow border black ; inner ochre
yellow, surrounding a white centre. Posterior wings are ornamented with a similar
eyelike spot, but surrounded by a large bluish black spot extending upward towards
the base of the wings : inner posterior angle truncate. Thorax traversed in front by
a narrow grayish belt, and connecting itself with a similar border on the front edge

of the wing. The wings expand to six inches.
The caterpillar inhabits the oak and elm, and may be found in August and September.
The absence of yellow stripes on the sides and transverse bands on the back, and the
presence of a mark of the shape of the letter be will serve to ace these caterpillars

from thoseof the ¢éuaa moth,

FAMILY LASIOCAMPAD. 237

ATTACUS CECROPIA. ( Plate xliv, fig. 4.)
Color dusky brown, reddish brown. The pattern of both pairs of wings is nearly alike.
The base is reddish, bordered with white. The broad middle is dusky brown, in the
centre of which are lunate spots, centrally white, but bordered with light brown.
The middle of the wings is traversed by a narrow reddish white band, beyond which
there is another broad dusky brown band ; in the outer and upper corner of which,
there is a black velvety eyelike spot, marked by a narrow lunate line placed upon
the inner edge : this outer border is bounded by a distinct black waving line, beyond
which is a white border edged with brownish. The posterior wings, however, instead
of the black waving line, have a row of black spots amounting to twelve or more,
placed by a dusky brown waving belt : margin dusky white. Expansion of wing,
six inches.

This moth appears early in the summer, in sheltered warm places : it is out as early as
the middle of May.

The caterpillar is of a fine light green color. The second and third rings bear two red
globular warts, around which are numerous bristles : the seven succeeding rings bear oval
yellow warts; and upon the eleventh ring, there is only one large wart. The sides are
ornamented with two rows of elongated blue warts, and the five first rings have an ad-
ditional row below.

The young is yellow, and marked with rows of small warts upon its back. It fastens its
cocoon longitudinally to the side of a twig : the cocoon is usually three inches long, tapers
from the middle, and is constructed of double walls of silk separated by loose fibres of the
same, and has a resemblance to brown paper.

The caterpillar is found upon several of our fruit-trees and shrubs, but I have never
been able to discover that its injuries were very serious. It is not very common : some
seasons, however, furnish more than others.

ATTACUS PROMETHEUS. ( Plate vi, figs. 1, 2, 3, 4.)

Mate, upper side : Color deep smoky brown; the shoulders and basal parts deeper than
the borders, succeeded by a central band of lighter color : this is terminated towards
the border by a wavy line, beyond which is the clay-colored border, ornamented on
the anterior wings by a wavy line, and on the posterior by black oblong spots between
the line and middle band. Outer angle of the superior wings is ornamented also by
a black eyelike spot, upon which there is a lunate line or crescent.

Femate, color brown, deepest upon the basal parts, which are marked by a curved whitish
line. Each wing bears spots, sharply Iunate on the anterior wings, and bordered by
black : besides which, the anterior wings are marked by an eyelike spot at their
angles, within a bluish white crescent. The moth expands about four inches.

The eggs are deposited on the twigs of trees in clusters,and are hatched in July. By the
first of September, or as late as the middle, the caterpillar acquires its full size, when it
measures about two and a quarter inches ; it is naked, of a green color, and marked by
six or eight small dark warts, and is furnished with a pair of simple coral-red spines for
the second and third rings. There is a short spine upon the last ring but one, and the last
is furnished with about six short black bristles.

The lilac seems to be the favorite shrub to which the prometheus attaches its cocoon,
which is about an inch long, and gray like paper ; it is attached longitudinally to a leaf,
that serves to protect and conceal it.

This moth is one of the most common in and about Albany, some lilacs furnishing as
many as a dozen cocoons. The caterpillar, though not perhaps entirely harmless, yet in
this respect scarcely deserves attention. The Jarge moths, appearing late in the season,
after the leaves are fully grown, do not seem as injurious as they might be if they arrived
when the leaves were expanding and tender; and trees do not suffer so much from the
loss of foliage in the early autumn, as in the spring.

Cerarocampa neGAtts ( Harris). Regal Walnut-moth.

“Antenne short, and, in the males, pectinated on both sides ; in the females, thread-like.
Wings without hooks : forewings olive-colored, ornamented with several yellow spots,
and veined with broad red lines.”

This insect I have not yet seen : it is fully described by Mr. Hannts, and, according to
his deseription, it is one of the finest and largest of our moths, having an expanse of wing
equal to six inches. The larve are spinous, but harmless ; that is, they do not sting when
handled. When fully grown, it is four or five inches long and three-fourths of an inch in
diameter, and of a green color banded with pale blue transversely*. It feeds on the walnut.

The moth is said to appear in June, and is more rare than the Dryocampa imperialis.

From the old family of Bomeyciwa or Saturnians, Dr. Hannis has separated the Cerato-
campa and Dryocampa, and a few others, and has constituted a new family under the name
of Ceaatocameans, after the name of the chief genus contained in it : the name signifies
horned caterpillars. On the second, and sometimes also on the third ring, these horns are
stiffer, more rigid and curved, agreeing more perfectly with their definition as Aerns.

All the species here referred to feed upon the leaves of forest-trees : they go into the
ground where they undergo their transformations, and this without making cocoons. The
chrysalides are notched or toothed, with the design of assisting their ascent from the
ground at the time just prior to their final and last change.

DryocaMpa PELLUCIDA. ( Plate xxxvi, fig. 1 - 3.)
a. Pupa : ¢. Larva (Anporr & Surrn).

Mate, upper side and forewings : Color of the costal margin and base brown, reddish and
purplish ; in the angle of this marginal and basal part there is a white spot : central
part clear ; posterior margin reddish or purplish. Posterior wings buff, similar to the

, antenne, head, thorax and abdomen.

Femace, buff with a white central spot ; outer margin paler. Beneath buff and uniform.

IT have a specimen of the male, the color of which is purplish buff without any variation
of tint, but preserves the pellucid wing with its white central spot. The wing is abraded,
but still has a close agreement with Mr. Harris’s description of the pellucida, which
certainly does not agree with Asporr & Smrtn’s figure.

Dryocampa VIRGINIENSIS. ( Plate xl, fig. 5.)

PHALNA VIRGINIENSIS (Drury), P. pettucrpa (Abbott & Smith).

Uprer stipe : Antenne, basal half doubly pectinated. Wings pellucid, brown. One half of
the anterior wings darker upon the upper part, in the middle of which there is a
single white dot : lower margin of the posterior wings lighter brown than the basal
parts.

Unper sine, the legs, sides, thorax and abdomen are dark orange. Wings divided into two
unequal parts by a bar : above the bar, the color is reddish yellow ; below, the same
as the upper side.

I have taken a single pair of this species in Albany county, and it is of rare occurrence
in this State, although during the present season (1853) it has been somewhat more nu-
merous, so that specimens have been obtained and placed in several collections.

The larva is described as being naked, striped, rigid, and supplied with acute tubercles :
the second ring has two threadlike horns. It subsists on the leaves of forest-trees : the
moths were found in a young forest of oaks and hickory.

The spring of 1853 has been unfavorable to the growth and perfection of this caterpillar :
at an early day they were quite numerous, but the subsequent cold weather seems to have
killed many in their tents. I have numerous balls consisting of dead dried caterpillars
inside of their habitations, which appear to have all perished from excess of cold when
about half-grown.

Cristocampa syLyatica (Harris). Tent Caterpillar of the Forest.

Head blue. First ring marked with two yellow spots and four black dots : the next eleven
rings are marked upon their tops by a row of white spots, and also two small elevated

240 ORDER LEPIDOPTERA.

black hairy dots, except that on the eleventh ring there is only one large dot. Sider
of the back marked by a reddish stripe, which is bordered by slender black lines :
they have also a yellow stripe between two black lines. Belly blue-black. Hanis.

This caterpillar inhabits oaks and walnuts ; less common on the cherry and apple. It
attains its full size in June, and is then two inches long. It is also social in its habits, and
constructs tents like the C. americana,

The moth appears early in September, and is of a light drab, brownish or yellowish
color. The anterior wings are marked by two oblique, brown, straight, and parallel lines.
The greatest expansion of wing is a little less than two inches.

The trees upon which the caterpillars of these moths feed are injured in the manner
represented in the foregoing sketch; and though few persons are so patriotic as to give
their services to the public for the purpose of destroying noxious insects, much private
benefit would accrue from the extermination of these forest caterpillars. To this end, our
special friends the birds come in aid, and rid us of thousands of them : the cuckoo, cat-
bird, robin, jay, and many others feed upon them, and thus diminish their numbers very
materially. The murderous gun should therefore never be pointed at birds who make it
their business to serve us so effectually, especially as we seem little disposed to do any
thing this way for ourselves ; and even were the disposition not lacking on our part, the
birds are certainly better adapted to do the work, and, no doubt, if spared by the fowler,
would be competent, from their consequent increase of numbers, to hold the increase of
insects so much in check as to save us from serious danger from that source. Indeed any
man has a perfect right to prevent the destruction of birds, on the same ground that he
has a right to protect himself from personal harm.

The direct means for destroying the forest tent caterpillar are the same as required in
the case of the C. americana, namely, destruction of the webs and their contents at the
proper time, that is, when the inhabitants are at home.

CLISIOCAMPA NEUSTORIA. ( Plate xxxvii, fig. 2-4, and a, g, pupa and larva.)

Primaries of the male pale sulphur-yellow, marked with two distinct dark brown bands :
the outer margin banded with brown, interrupted with two oblong sulphur-yellow
spots near the outer angle. Secondaries dull brown, with a deeper marginal stripe
parallel to the posterior margin,and marked with deeper brown also on the nervures
running from the base to the posterior margin. Fremare yellow, inclining to orange on
the primaries, with the same distribution of brown and brown stripes as in the male.

Carerrittar green, with a row of oblong white spots on the back, enclosed in rectangular
markings of yellow, which are formed by two yellow parallel stripes upon the sides
of the back, connected regularly with serrated cross bands : enclosed rectangles

hairs, and brushes on each side of the head ; when mature, two inches long. The tail
is terminated by an oval spot surrounded by yellow enclosing green and white, the
white in the form of a stripe.

Cocoon bluish, oval, tapering, with eight rings, and dotted along the sides ; less than one
inch in length.

This insect feeds upon oak leaves, and does considerable damage to the white oak by
nearly defoliating it. The caterpillar appears as early as the first of May. It is regafded by
Asnorr and Smrru as identical with the European insect of the same name. (See Ansorr
and Smrru’s History of the Insects of Georgia, pa. 117, pl. 59; and the figures I have
given are those of Ansorr and Smirn, from which it will appear, on reference to plate xlv,

that they differ from those of our common orchard moth named by Dr. Harnis Clisiocampa
americana.)

Hepialidae.

Tue antenne of the insects of this family become gradually attenuated at the tip : they
are short and filiform, but never feathered at the tip ; but those of the males are some-
times doubly pectinated at the base. The tongue is either very short or obsolete. The
abdomen is elongated, and provided with an ovipositor. The thorax is never crested. The
wings are narrow, but complicated and strengthened by numerous nervures. The larve
have sixteen feet : they are white or reddish, soft and naked, only slightly downy, and
furnished with brown heads : they feed upon wood, and construct their cocoons of bits of
the wood upon which they have been feeding. The chrysalids are ridged transversely, and
notched.

This family does not appear to contain many species in this country. Dr. Harris has
described the Hepiolus argenteomaculatus belonging to the same genus as the European

hopvine hepiolus, and figured the same in the Lake Superior Expedition conducted by
Prof. Acassiz, plate vii, fig. 7.

Notodontidae.

Tue wings of the moths of this family are folded, and slope like the roof of a house over
their backs : they are held by bristles and hooks. The antennz are rather long, usually
doubly pectinated in the males, and become narrow and short towards the tip. The feelers
and tongue are small and short ; the body is long.
The larve are provided with toothlike prominences upon their hunched backs : they
are usually naked, or only downy. The posterior appendages used for feet are sometimes
[ AcricutturaL Rerort—Vot. v.] 31

modified so as to exhibit a forked shape, upon which the soles of the feet only are seen.
The cocoons are formed of silk intermixed with fragments of wood and bark. The chry-
salids are not notched upon the back. The larve feed upon leaves.

Pycana ALBIFRONS. ( Plate xxxvil, fig. 3-5.)

Wings deflexed : primaries clouded ; anterior margin marked with an elongated spot of
cream-color terminating in the outer angle and dotted slightly with brown, trans-
versely banded with white, black or dark brown ; secondaries brown, margined with
a lighter shade. Thorax of the male banded with two distinct black lines joined by
two short parallel connecting lines, between which there is a square yellow or cream-
colored or light buff spot. The thorax of the female is ornamented with three cross-
bars : antenne setaceons, with a terminal enlargement. Antenne of the male?

Carexritian striped upon its back with yellow and brown ; underside lake, and furnished
with three pair of legs and four pair of proplegs : it is half an inch long. It spins a
thin white web between the leaves late in autumn, and appears early in the spring in
perfect state, feeding upon the leaves of the white and other oak trees. They are
gregarious when young. The cocoon is } inch long, and has eight or nine segments.

The larvee of this species feed at times upon the leaves of the oak, and sometimes nearly
defoliate a tree when they are numerous. An instance has fallen under my observation, in
which a tree of this kind was well nigh deprived of leaves by these insects for two or
three years in succession.

Evpryas crata. Woodnymph. ( Plate xlvii, fig. 8.)

Forewings pearly white ; basal half trimmed with purplish brown ; outer margin widely
bordered with purplish brown, the inner edge of which is banded with olive, which
extends and widens upon the posterior border, forming near the middle a large patch :
exteriorly, upon the border and near the edge, it is ornamented with a delicate bluish
line. Hindwings a yellow buff, bordered behind with purplish brown, which does not
reach the outer angle, but extends along the inner edge : it is trimmed with silver-
gray cilie. Brexsatu, the forewings are pale buff, marked upon the basal half with
brown, but confined to the costa, which terminates in two roundish spots. Hindwings
paler yellow buff, and marked in the middle with a single brown spot. Abd a iad
brown, silky; the rings are banded with lighter, and terminated with a zone of the
lighter buff.

This beautiful moth is rare here. I have taken it only in Berkshire ( Massachusetts),
but it exists in collections in Washington and Albany counties in this State.

FAMILIES NONAGRIADZ AND AGROTIDA. 243

Nonagriadae,

Tue body of the moths of this family is long; the thorax is smooth; the colors are yel-
lowish or clay-colored, and the forewings are faintly streaked or banded. The Jarve are
naked, long and slender, and taper at each end : they live within the stems of reeds, and
feed upon the pith and upon the inside of roots, and hence are destructive. When about
to transform, they gnaw through the stem to the cuticle, which is left entire, but is easily
broken through afterwards by the nymph. They are known by the common name of
spindleworms. Some attack corn, to which they do great injury ; others, the stems of garden
flowers, such as the dahlia, ete.

The Gortynta zea of Harris belongs to this family, and is described by him as having
its forewings of a rusty red, and. mottled with gray almost in bands : there is also an
irregular tawny spot near the tip, and on the veins a few black dots. Expanse of wing,
an inch and a half.

Another Gortynia attacks the roots of columbine, and has been named by Dr. Harris
teucostigma. The forewings are tawny yellow, sprinkled with purple brown dots. (See
Hanruis, Insects injurious to vegetation, p. 341, 2d edition.)

Agrotidae.

Tue larve of this family are subterranean, and come forth from the soil to feed in the
night, and return to their burrows before morning : they are called cutworms, and are
exceedingly troublesome in cornfields. The moths are usually brown, and sometimes fly
by day, and feed upon the honey of wild plants : their wings are nearly horizontal when
at rest, and the forewings completely conceal] the hind ones when closed. The thorax is
not crested. The antennz of the males are sometimes pectinated at the base, but taper to
slender filaments. The forelegs are spiny.

The larvx are smooth, cylindrical, dirty white, and rather thick bodies, naked or fur-
nished with only a few scattering hairs : their rings are dotted. They change to chrysalids
in the ground.

The attacks of these larve extend to many of our most useful cultivated plants, corn,
cabbages, wheat, buckwheat, grasses, together with cultivated flowers. In the maize-fields,
however, about the middle of July, they seem all at once to cease their injurious work to
the corn plants.

It appears from Dr. Harnris’s researches that we have many different species of this
family, all of which have the similar habit of feeding upon young and tender plants, and
of cutting off their stems just above the soil.

Acxotis ——. ( Plate xlv, fig. 11.)
Color dusky brown. Forewings dusky or blaekish, especially along the costal edge : one
half of the subcostal base is blackish ; and, beyond the middle, this dusky subcostal
band extends towards the inner margin, forming a partial transverse band : apical
and marginal area light brown and silky, of the same color as the area of the dise.
Hindwings white with a pinkish hue in certain lights, silky and ciliate ; beneath,
quite pale, and without markings. Body dusky, and as dark as the forewings : the
venter is slightly ferruginous, and terminates in a short brush. Expanse of wing,
two inches.
This is one of the common species of Agrotis in Western Massachusetts and Eastern
New-York.

Acrotis ——. ( Plate xlv, fig. 2.)

Color mottled gray : thorax and head brown. Forewings gray at the base : in the middle,
resting upon the inner margin, is a large quadrangular spot of a cinnamon-brown,
beyond which is a broad transverse grayish green band ; margin brown : costal mar-
gin mottled with gray and brown, with an intermixture of short slender transverse
lines. Hindwings smoky, especially upon the posterior and inner margin : costa
pearly and yellowish white, beneath smoky and pearly. Hindwing beneath marked
with a central black dot. Expanse of wing, two inches.

A common species in Western Massachusetts.

Acnotis? ——. ( Plate xlv, fig. 10.)

Color of the thorax black, from which a longitudinal band extends upon the forewing,
reaching its middle ; the extreme end, however, is separated from it by a small space
of gray. Costa black in front : outer margin banded transversely by two dusky white
bands, between which are broader bands of dusky brown. Hindwings pearly white.
Abdomen whitish, or of the color of the hindwings.

Noctuidae.

Tue antennie of the insects of this large family are mostly simple : the bodies are thick,
stout and strong ; their wings are of a moderate length, and strengthed by their nervures,
and their tongues are long. The wings, when not in use, are deflexed upon their sides, and
the body is clothed with scales rather than wool or hair. The majority of the larve of
the different genera are naked, and have sixteen feet, though in some the second ventral
pair, in others the first ventral pair, are wanting : they undergo transformation under
ground, and form cocoons of silk in which particles of sand are often glued. The moth

FAMILY NOCTUIDA. 245

flies by night, and conceals itself during the day : its thorax is crested. The larve are
solitary. The colors of the perfect insect are not bright, but often have a silky lustre.

248 ORDER LEPIDOPTERA.

There seems to be considerable variation in the size and colors of this painted moth,
possibly due in part to sex. In the figure of Davay, the anterior wings are dark, with
yellow marginal dots. A Catocala found in Western Massachusetts has the dark anterior
wings and dotted margin; while the moth is larger, the red belis of the hindwings are
brighter, and the posterior margin is almost ciliate and yellowish gray. But another, near-
ly as large, is pale and ashen, and the inferior wings have yellow instead of vermilion red.
Another still is small, about 14 inch in expansion, with yellow also; but has the angular
spot, and other markings similar in fashion to Dauxy’s figure.

There seem to be gradations both in size and depth of coloring, which are not sufficient
to distinguish species, but may establish varieties ; but as I have before me only six in-
dividuals, I may be mistaken in my estimate of the importance of their differences.

Geometridae.

SPANWORMS, LOOPERS, &e.

Tue insects of this family move over the ground, or along the branches of trees, in distinct
steps, as if measuring their progress, by alternately flexing and extending their bodies from
point to point. The manauvre is performed by first extending the anterior extremity of the
body as far ahead as it will reach, and then bringing forward the posterior extremity by
elevating the middle portion of the body, so that the extremes are brought into contact,
and the whole takes the form of a loop; and thus by successive steps they measure their
route according to the length of their bodies. Their legs, which are usually ten on each
worm, are employed rather in fixing the body at its successive points of rest, than in in-
dependent movements of the feet. They necessarily move slow ; and as they oceupy bushes
and trees in feeding, and must seek the ground to undergo transformation, they are pro-
vided with the apparatus and means of spinning a thread, by which they are enabled to
let themselves quickly down to the ground ; and in cases of alarm they frequently do this,
remaining suspended until the danger is past, when they return to their feeding by aid of
mouth and feet, seizing the thread above with the jaws,and then drawing up the body by
doubling it as before described. They are destitute of hairs.

When the spanworm goes to rest, it fixes itself by the posterior feet, and lifts its body
up and sustains it stiffly in an angular and motionless posture, thereby counterfeiting the
appearance of a short broken dead twig of the branch on which it reposes, with the instinct
of eluding if possible the searching eyes and devouring beaks of hungry birds.

To the Family Gromeraips belong some of the most destructive moths, particularly
the cankerworms. Those which are injurious to fruit-trees have usually thin angulated
wings ; but they are wanting in the female, or merely rudimentary, and hence are very
unequal in this respect : this fact gave origin to the name anisepteriz, ‘unequal-wings.’

PHALENA CATENARIA. BupaLus CATENARIUS ( Leach).

Antenne in the male doubly pectinated, slender. Head orange. Thorax, abdomen and
wings white : the former is marked with three orange-colored spots, and each ring
of the abdomen with dots or black transverse lines ; the wings are also marked by
two parallel denticulated lines running across them. The wings are rounded behind,
and margined with a black dotted line having some resemblance to a chain. (See
Westwoop, Illustrations of Drury, plate viii, fig. 3.)

GromEeTRA ? ——. ( Plate xlv, fig. 3.)
Wings subangulated, subcrenate on the outer margin.

This moth I am disposed to refer to the Genus Gromerra, relying upon the form of the
wings and the pattern of their ornamental marking. The color is cinnamon-brown, and the
white transverse band near the middle is bordered by a deeper brown on the basal side.
The costa is darker, being connected with the transverse band already referred to. Hind-
wing lighter colored at the base than the outer half.

I have been unable to obtain the larva, and hence it cannot be determined whether it
has the progression peculiar to the geometride. There is some doubt as to the genus to
which it should be referred.

Tortricidae.
LEAF-ROLLERS.

Tue insects of this family mostly have the habit of rolling up the young leaves of trees,
either one or more ina single roll,and confining them with silken threads. They are small,
seldom in the larval state exceeding an inch in length. The moth is nocturnal, small,
usually gray and obseurely banded, rarely ornamented with bright colors. The larve have
sixteen legs each, and their bodies are naked, or only clothed with a few hairs in tufts :
they spin a thread of silk from the mouth, with which, when disturbed, they let themselves
partly down to the ground, where they remain suspended until the danger is past. The
moth, though small, is broader across the forepart than in those of other families. They
inflict serious injuries upon trees, by feeding on the buds and blossoms.

Loxoran1a nosaceanal Rose Leaf-roller. ( Plate vi, figs. 8 - 11.)

Color light brown, grayish brown, light cinnamon-brown. Forewings traversed by two or
three narrow brown bands : when the wings are closed, the bands form a quadrangu-
lar figure on the back ; these bands are variable, as well as the colors of the moth.
Hindwings yellowish white or grayish yellow. Expanse of wing about one inch.

The larva is green, naked : head brownish, smooth, glossy : rings of the integument
sheathing the head, yellowish white : six true legs, eight middle and two prop-legs.
At the extremity of the abdomen, two or three smal] greenish warts, which give
origin to a few hairs. Feeds upon plum, rose, and other leaves and flowers. Largest,
three quarters of an inch long; sometimes one inch, but usually a little less : the
figure is smaller than common. 4

The pupa is brown, enclosed in the rolled leaves, and suspended by the tail.

This is a very troublesome insect. In my garden, the larve every year destroy most of
the plums on a fine tree, besides checking the regular growth of the young limbs, which,
when the buds are destroyed, never grow more than an inch or two in the spring; and the
effects of the insects are also seen in the knotty condition of the young shoots. The eggs
are laid in patches upon the bark in the month of June or July, where they remain until
the tree begins to put forth its leaves, when the larve make their appearance, and almost
every twig has been for some years infested with them.

The best way to deal with this species of Tortriz, is to rub the bark of the trunk and
limbs of the tree with a knife or some other proper instrument, by which means the eggs
will be destroyed ; and then wash the bark thoroughly with an alkaline solution, or with
whale-oil soap : or if the trunk and limbs are whitewashed in the autumn or spring, just

FAMILY TORTRICID. 251

as the eggs are about to hatch, it will mostly destroy the eggs ; and if any escape, the use
of a syringe with soap and water, will probably finish the work.

This leafroller attacks the rose, and several other plants belonging to the different
orders : it is not, therefore, particular as to its food ; but it effectually puts a stop to the
expanding blossoms, whenever it makes its habitation in the leaves that surround the bud.

I have referred this inseet to the species rosaceana, although it does not agree in every
respect with the descriptions within my reach. It is variable in its markings and size, in
both the larval and perfect states. It does not spin a cocoon, unless one is constituted by
the few threads of silk it employs to bind up the rolled leaves with, in which its trans-
formation takes place.

CARPOCAPSA POMONELLA. ( Plate xIvii, fig. 4.)

This insect is a native of Europe : it was brought to this country with the apple, and
has become naturalized. The moth is gray, but lustrous like satin, and is delicately streaked
and dotted. The posterior border of the forewing is marked with a reddish brown spot,
which is surrounded by a golden mark in the form of a horseshoe. The hindwings are
brownish inclining to yellow, and surrounded by a fringe : they are sparkling and bril-
liant. The thorax and abdomen are yellow and brownish gray. '

The moth appears in the evening, having been secreted in a secure place during the
day. It may then be seen busy about branches of apple and pear-trees, selecting the fruit
for a depository of its eggs : in a few days, if the weather be warm, they are hatched. It
requires three or four weeks to come to perfection, when it is reddish or flesh-color, with
a brown head and collar. Before it changes to a pupa, it leaves the fruit, and seeks a secure
place in the cracks of the bark, where it spins its cocoon.

According to Kotiar and other authorities, two broods are produced in a single season.
The first pupa changes to a perfect insect in a short time, and, by the last of August, much
fruit will be injured. If the weather and season be favorable, numerous insects of this
kind will come to perfection, and the quantity of fruit injured will be in proportion to the
number of insects hatched from the eggs of the first brood.

The means to be adopted for diminishing the numbers of this moth, are mostly of the
palliative kind. It is evident that all infected fruit should be immediately gathered and
destroyed. The tree should be shaken, that all diseased fruit may fall as soon as possible,
and before the larva leaves it to change into the pupa state. The defective fruit may be
picked, removed and scalded, and fed to swine. It is obvious that the nearest approach to
the extirpation of this injurious insect will happen when cultivators of apples and pears
shall unite their efforts in the use of the remedies proposed.

Yponomeutidae. ©

A vasity of the Lerivorrmaa, made up of very small moths, whose labial palpi are long
and slender, and still but slightly developed : it is allied to the Towrricioa and Tixeiwwa;
but from the former it differs in the length of the prlstcene from the latter in their non-
development. ne

The body of the insect is slender, and somewhat elongated and. deveeditegatelae
are very long and simple in both sexes. Wings also long, or a long oval and acute : they
are entire, but often ciliate or fringed. The colors are white or slate, marked by a few
bands of black : some, however, are ornamented with brilliant metallic colors.

The larve are often highly injurious to fruit-trees, especially those living in communi-
ties, which Inhabit a common tent after the manner of the American tent caterpillars.
They have sixteen feet, and form cocoons in the midst of their webs.

Plate xIvii, fig. 7, represents the typical form of the family : it is the Adela degeerella,
from Westwoop. The species have not always the long antenne of this one.

Tineidae.

Tus family contains some of the smallest of the Leriportena. Their wings are narrow, in
which respect they differ from the Toatuictoaz:; and their palpi are well developed. The
head is often densely clothed with scales in front : the antennz are only moderately long ;
the spiral tongue is short ; and the wings are entire, but convoluted when at rest.

The larve are very destructive to woollens and household furniture, carpets, clothing,
furs, ete.; and when once they have taken possession of a house, it is difficult to dislodge
them. They are usually of a dirty white, sometimes of a brown color, with long hairs from
the posterior extremity ; but sometimes also naked, or furnished with a few hairs seattered
over the body. They form cocoons, which they frequently carry about with them; and
their depredations consist in gnawing holes through the woollens, and other goods, when
they get possession of them ; so that when unfolded and held up to the light, the articles
are often found to be perfectly riddled. They undergo transformation in the little cases or
cocoons they have formed, and which may often be found in great numbers adhering to
spots where they were fixed by the larve when about to undergo transformation. ==

One of the most effectual modes of preserving woollens, furs, ete. from the depredations
of the moth, is to expose them to sunlight, and subject them to frequent examinations.
When such articles are kept in dark closets, and left undisturbed during the months of
June and July, they will suffer more or less from moths. Tobacco leaves, camphor, tur-
pentine, are poisonous to the moth, and may be employed as protectives against it.

_ FAMILY TINEID, 253

TrneA cereLia (Fabricius). Honeycomb Moth.

This moth is notorious for its depredations in the beehive : its larva feeds upon the
honeycomb, or beeswax.

Kotxar, in his treatise on injurious insects, describes this moth in detail ; and from the
matter he has furnished, I have derived the following facts :

The color of the male is yellowish; the antenne, head and back clay-yellow; the
abdomen yellowish brown, and feet yellowish gray with lighter spots. Upon the back and
behind the scutellum there is a blackish brown tuft of hair, the point of which is white.
The upper wings are broad, short and obtuse, of a dusty ash-gray, banded from the base
to the middle, and dotted with brown : the fringes are brownish white and jagged. The
hindwings are light ash-gray, marked by a yellowish spot cn their inner boundary.

The female is larger than the male : her color is of a dark rusty brown on the head
and back; the forewings are darker, obtuse and straight, while the hindwings are much
lighter. Length of the male, six lines : expanse of wing, one inch.

The caterpillar is cylindrical and spindle-shaped, and, when fully grown, is nearly an
inch long : it is of a dirty white color, and has sixteen feet of a cream-color.

Following its singular instincts, the larva, immediately after it is hatched, forms its web
of silk, which becomes for it a covered way and protecting screen, wherewith it boldly
enters the hive if hatched without, and establishes its home in the midst of enemies.
When the bees are at work, however, it does not appear abroad; but when they are at
rest during the night, it feeds voraciously upon the wax. It increases rapidly, and comes
to its full size in about three weeks : it then makes its web stronger, and is transformed
to a pupa. If it is late in the season, it remains till spring before it changes to an imago.

The effect of these intruders is first to diminish the wax of the bee-cells, which occasions
the loss of the honey ; and when this takes place extensively from the presence of nu-
merous larve, the bees cease working.

There are two generations of moths in a season, according to Koxar ; the first appearing
early in the spring, and the second in July. The female lays her eggs in the cracks of the
lower part of the hive, in the night, and the larve feed at first upon the young comb; but
they afterwards ascend to the upper part of the hive, where the older kind is deposited.

Many inventions have been proposed and resorted to, to secure the bees from these
intruders : none, it is said, sueceed perfectly ; and so far from requiring no attention, it
is maintained by Koxrar that the only sure method of cleansing beehives from this moth
is to look after and destroy them, both larve and pups. The moth is fond of sweets, and
may therefore be attracted to dishes of sweetened water and vinegar in the night, and by
that means may be drowned : some other kinds of obnoxious moths may be destroyed in
the same manner.

Ruuwosta romete.ta. Chatochelus pometellus (Stephens).

A moth has been described by Drs. Hannis and Frren, belonging to the family Tixe:p»,
which has done considerable damage to the apple orchards in the vallies of the Hudson
and Housatonic during the spring of 1853. Dr: Hanars has called it Rhinosia pometelle,
and furnishes the following deseription :

‘ Forewings ash-gray, sprinkled with blackish dots, three of which are larger than the rest,
‘and placed triangularly near the middle : a dusky transverse band near the tips,
‘and a eurved row of seven black dots at the origin of the terminal fringe. Hind-
‘ wings dusky, with a leaden lustre, black veins, and very long black fringes. Body
‘and legs beneath yellowish white, with the lustre of satin. Expansion of wing, five
‘ eighths of an inch’ ( Journal of the N. Y.S. A. Society, September). The markings,
however, according to Dr. Frrcu, are somewhat variable.

The larva is cylindrical, has a pale greenish color, sixteen feet, and a dusky stripe on
the back : above this is a narrower whitish stripe, which runs along the middle of the
back. The head is yellowish and polished. Length about half an inch. Its marks and colors
are variable.

This larva has inflicted considerable injury upon orchards during the past season (1853).
It eats not only the leaves, but also the apples. Like the fortriz, it sometimes rolls up a
leaf for a habitation ; and when the tree is shaken, many let themselves down by threads
of silk.

Whale-oil soap, dissolved in water and thrown freely upon the trees, is found to be an
effectual remedy against this insect.

Butanis CEREALELLA. Angoumois Grainmoth.

Color pale cinnamon-brown ; lustre silky : hindwings ashy or dusky lead-color : feelers
blackish near the tip ; second joint blackish on the outside : body pale brownish gray.
The head is smooth : antenn# threadlike, jointed : feelers long and curved upwards,
with the terminal joint naked and acute ; basal joint hairy and short : tongue about
half an inch long, and spirally coiled. Forewings rather long and narrow, pointed at
the end, and fringed : surface sprinkled with blackish dots, especially near the tips.
Hindwings blackish with a leaden lustre, narrow,and obliquely contracted to a point
at the tips : fringe blackish, widest on the inner margin. Forelegs blackish ; hind
ones fringed on the inner side with long hairs.

The caterpillar, when fully grown, is whitish with a brown head : legs six, with ten
wart-like proplegs. Chrysalis is obtuse at both ends : rings of the body smooth : wing-
cases extending nearly to the hinder extremity. The skin of the chrysalis remains in the
kernel of grain upon which the larva has fed. The insect hatches from June till August.

FAMILY TINEIDZ. 255

The community is greatly indebted to Mr. Harnis, for his discoveries in relation to the
Angoumois grainmoth. He had expressed his conviction, in the first edition of his treatise
on insects injurious to the farmer and to vegetation, that a certain grainmoth would prove
to be the true European angoumois grainmoth, and it seems that this prediction is fully
sustained by farther discoveries of our indefatigable and distinguished entomologist.

This insect, in its perfect state, is known to lay from sixty to ninety eggs in clusters of
twenty or more upon each grain : these hatch in about five or six days into threadlike
worms, which disperse themselves about the grain-bin. After selecting a kernel by fixing
upon its tender part, the worm burrows into it, and there remains feeding until it arrives
at maturity : it then spins a web, dividing its cavity longitudinally into two unequal parts
by a silky partition, where it undergoes its transformation, the larger cavity serving the
purpose of a cocoon.

It appears that infected wheat, when sown, may germinate, but the plumule will be
weak and small : the insect, however, still remains in the grain, feeding upon the starchy
matter, till it is ready to undergo its changes. These take place while the grain is still in
the field, and the mature insects may be found flying about the fields in the night, and are
ready in due time to deposit their eggs in the growing grain.

It appears that the angoumois moth not only attacks wheat, but also indian corn. Mr.
Ricnarp Owen, of New-Harmony, first called the attention of the public to this fact in a
communication to the Cultivator in 1846. In indian corn it attains a rather larger size than
in wheat, the wings expanding to about six-tenths of an inch.

The method that has been found most effectual in destroying this grain-worm, consists
in exposing the grain to a temperature of 167° Fahr. for twelve hours ; or if the heat is
pi 104 or 5°, it is sufficient to destroy the worms, provided it be continued for forty-
eight hours. Fumigation is another remedy which has been successfully employed. Expo-
sure to cold destroys both the larva and its eggs : if the grain, for example, in New-York
and New-England, is housed when it will be exposed to a cold at zero, the insect will be
destroyed.

In addition to the foregoing, it is recommended to thresh the grain at an early day ;
inasmuch as by that operation the insect is destroyed to a great extent, after which the
grain may be preserved in bulk. Grain, however, should not be exposed in open casks
when it is liable to become infested : the insect may be excluded by keeping the grain in
closed boxes or hogsheads after threshing. Corn in the husk, too, is less exposed to de-
predation than when husked, especially when it remains standing in the field.

‘Tiwka cnawetta. European Greinmoth. >

Forewings marbled with white or gray, light brown and dark brown spots, and one square
dark spot near the middle of the outer edge. Hindwings blackish. Head tufted.
Length three- to four-tenths of an inch. Hanis.

Moths appear in May, June and August ; they breed twice a year.

The caterpillar of this grainworm, instead of burrowing in the grain like that of the
angoumols grainworm, feeds upon the external surface only, and spins a web in which it
entangles several grains for that purpose. When the period for transformation arrives, it
leaves this web, and seeks a crevice in which to spin its cocoon. Altogether they occupy
about six weeks in feeding on the grain, which they soil and otherwise injure by covering
it with their webs and excrements.

Such are the characters of the European grainmoth. It appears from the observations of
our distinguished entomologist, Dr. A. Fitcu of Salem, that he observed many years ago
that grain in some of the mills in his neighborhood was affected much in the way described
above, only the caterpillar formed its cocoon within its web.

Although the habits of the foregoing grain insects differ somewhat, the remedies that
have been successful in destroying one are equally efficacious against the other, to wit ;
fumigation with carbonic acid ; exposure in close vessels to heat of 130 to 140° Fabr.
