REPORT OF THE ENTOMOLOGICAL SOCIETY OF ONTARIO, FOR THE
YEAR 1879.

Te the Honourable the Commisioner of Agriculture:

Sir,—In accordance with the provisions of the Statute, I have the honour to sub-
mit for your consideration the Annual Report of the Entomological Society of Ontario

for the year 1879, in which is contained an account of our financial condition, the reports
of the Council and of our severai branches, also such papers from our members as we
think most adapted to the wants of our agriculturists, and most likely to further the
design of the Department in promoting the knowledge of practical Entomology.

The Canadian Entomologist has now completed its eleventh volume. Appearing
as it does monthly, with an ever widening circle of influence, it cannot but have great
and beneficial effects upon the agricultural interests of the Dominion, rendering by
timely warning and advice, such information as has afforded much protection against tke
noxious insects that are ever invading our crops. It has been well supported by able
contributions from our members and is favourably looked upon by its readers.

Were our funds sufficient we would gladly introduce a much greater number of
appropriate cuts which would make our journal more acceptable and valuable to the
community, as, with suitable illustrations, the articles it contains would be much more
readily understood.

The annual meeting of the Society was held at Ottawa, at the time of the Dominion
Exhibition, when the reports of the officers, duly audited, were presented and approved of,
also officers for 1880 were elected. The Society’s collection of insects was on exhibition
there and was awarded the Dominion Gold Medal.

The articles contained in the report are, we trust, such as will prove interesting and
useful to the public and especially to agriculturists, for whose benefit they are par-
ticularly intended. We also trust that they will meet with your approval.

I have the honour to remain, Sir,
Your obedient servant,
James H. Bowman.

ANNUAL MEETING OF THE ENTOMOLOGICAL SOCIETY OF ONTARIO.

The ninth annual meeting of the Entomological Society of Ontario, was held in
Oitawa, in the Museum of the Ottawa Literary and Scientific Society, on Thursday the
25th of September, at 4.30 p.m. In addition to the members of the Society, there were
present on invitation about twenty members of the Ottawa Field Naturalists’ Club.

In the absence of the Secretary-Treasurer, Mr. Jas. Fletcher was appointed Secre-
tary pro tem.

The President read a telegram which he had received from the Vice-President, re-
gretting that important engagements prevented him from being present.

The annual statement of the Secretary-Treasurer was read and adopted.

REPORT OF THE COUNCIL.

Your Council feel highly gratified at the success which has attended the efforts of
the Society during the past year. Nine years have now passed since our incorporation ;
these have all been prosperous years, and the one we have just completed has not been
less so than any of its predecessors. All the operations of the Society have been carried
on harmoniously, and we have been able to present the public with many of the results
of your investigations which will prove of value to it.

Our Report to the Government, which you have all had the opportunity of perusing,
continues to maintain its interest, if we may judge by the manner in which it is sought
after. We think that it is perhaps our best medium for reaching those whose know-
ledge of Entomology is limited, and to whom it is necessary to present the science in
its more elementary and popular forms, if we would create a taste for its study. The
fact that our reports are so much in demand indicate that the science of practical
Entomology is rapidly growing in favour among the more intelligent of our
agriculturists.

The new enterprise of the ‘‘ Fruit Growers’ Association,” the publication of the
Horticulturist, to the pages of which your members contribute largely, will, we trust,
be a means of still more widely diffusing Kntomological knowledge, as this journal
enters the homes of nearly all our horticulturists, and in addition to the many valuable
papers on fruits and flowers which it contains, it carries much information on our
noxious and beneficial insects.

One great drawback to the Society’s efforts has been the lack of funds to carry on
its operations, and to enable us to procure woodcuts and electrotypes to illustrate the
pages of our journal. We are satisfied that without figures of the insects we treat of,
much of our labour is lost as far as the general public is concerned ; we earnestly hope
that before long our annual grant may be sufliciently increased to enable us to overcome
this difficulty.

Our journal, The Canadian Entomologist, has now completed its eleventh year, and
has made a reputation for itself which is second to none in the same department of

4

science ; it has been regularly issued and has always been well filled with useful matter.
The articles have been almost entirely original, and any new developments in Entomo-
logy have been promptly recorded in its pages.

The meeting of the Entomological Club of the American Association for the
Advancement of Science, was held at Saratoga, commencing on the 26th of August.
Our society was represented by the President, Mr. Wm. Saunders, and the Vice-
President, Rev. C. J. 8. Bethune, M.A.

It has been decided to exhibit our collection of Canadian insects at the Dominion
Exhibition at Ottawa, and our collection of foreign ones at the Western Fair in Lon-
don. ‘The Ottawa collection is formed of the bulk of our Centennial display, so that
those members who visit Ottawa, who have not before seen our collection, may be
enabled to judge of its value.

Our branches in Montreal and London are still carrying on a successful work, and
join the Parent Society in hailing the coming year as one of increased usefulness and
success.

Submitted on behalf of the Council, by
Jas. H. Bowman,
Secretary- Treasurer.

Mr. Couper then read the report of the Montreal Branch, indicating very satisfac-
tory progress ; this was referred for publication.

The annual address of the President was next in order, after the reading of which
a vote of thanks was tendered to him, both in the name of the Society and also in that
of the Ottawa Field Naturalists’ Club, for his exceedingly interesting and instructive
address, and a copy was requested for publication in the Annual Report.

ANNUAL ADDRESS OF THE PRESIDENT OF THE ENTOMOLOGICAL
SOCIETY OF ONTARIO.

To the Members of the Entomological Society of Ontario :

GrntLEMEN,—Again it is my privilege as your retiring President to address you, to
draw your attention to Entomological subjects, and more especially to the operations of
the insect world about you, and to record the progress or decline of those noiseless dis-
turbers of our peace—injurious insects.

The City of Ottawa being one of the great centres of our lumbering interest, it
seems fitting that I should on this occasion call your particular attention to some of
those insects most injurious to our pine forests. The losses occasioned by the destruc-
tive work of borers in pine trees, both before and after they are cut, are unfortunately too
well known to those interested in the lumber trade, although the sufferers may not be
familiar with the life histories of their enemies so as to be able to recognize them in
the various stages of their existence. The lumberman suffers from the work of a num-
ber of destructive species, nearly all of which inflict their greatest injuries during the
larval stage of their existence.

There are three families of beetles in which are included the greater number of our
enemies in this department. I allude to the longicorns or long-horned beetles, Ceram-
bycide ; the serricorn or saw-horn beetles, Buprestide, and the cylindrical bark beetles,
Scolytide. To go over this long series in detail would weary you. A brief sketch of
the life history of a single example in each family will serve as representatives of the
whole.

One of the most destructive of the species included in the Cerambycide is a large
grey beetle with very long horns, known to Entomologists under the name of Monoham-
mus confusor, and popularly in this district as the ‘‘ Ottawa Cow.” Where trees have
become diseased from any cause, or where a fire has ravaged a pine forest and scorched

Gr

and partially destroyed the timber, or where logs after being cut have been allowed to
remain a season in the woods or in the mill yard—there these insects gather and soon
ultiply to a prodigious extent. The mature insect is over an inch in length; the
antenne of the male reaches the extraordinary length of from two to three inches,
while those of the female are shorter. The female lays her eggs in the crevices of the
bark, where the larve when hatched eat their way into the wood, burrowing extensive
galleries through the solid timber ; when mature they are large, white, almost cylindri-
cal, footless grubs. They pass their chrysalis stage within their burrows, and the per-
fect insect on its escape eats its way out through the bark. There are about a dozen
species in this family known to be destructive to pine.

Most of the insects belonging to the family Buprestide may be recognized by their
brilliant metallic colours; they have very short antennz which are notched on one side
like the teeth of a saw, and are often hidden from view by being bent under the thorax.
Chalcophora liberta is one of the most destructive to pine trees, and its history is very
similar to that of the long-horned beetle just described, but the larva is of a different
form, and has the anterior segments or rings of the body very large, reminding one of
the appearance of a tadpole. The perfect insect is about three-quarters of an inch long,
of a brassy or coppery hue, with the thorax and wing-covers deeply furrowed by irregu-
lar longitudinal depressions. Dr. Fitch enumerates twelve species belonging to this
family which are known to be injurious to pine. Additional information in reference to
these beetles may be found in an article contained in the last annual report of our
Society, by Mr. J. Fletcher, of Ottawa.

The cylindrical bark beetles, Scolytide, are also a numerous family, eight species of
which are known to attack pine. The boring Hylurgus, Hylurgus terebrans, is probably
one of the commonest. This beetle is about a quarter of an inch long, of a chestnut
red colour, thinly clothed with yellowish hairs, and is found during the month of
May. The larva, which is a small yellowish white footless grub, bores winding passages
in every direction in the inner layers of the bark of the tree, and also through the outer

_ surface of the wood.

In some parts of our Province pines are greatly injured and sometimes killed by
the attacks of a woolly bark louse, which covers parts of the trunk and branches with
a white cottony secretion, under the protection of which myriads of tiny lice live,
puncturing the bark with their sharp beaks and exhausting the trees by feeding upon
the sap.

While we are mainly interested in the preservation of our mature forests, the future
of our country demands that we shail not overlook the young growth on which the lum-
ber supply fifty or a hundred years hence must largely depend, and which it should be
the policy of our rulers to protect as far as possible. Most of the governments of
Kurope are now fully alive to the importance of this matter, and are annually spending
large sums of money in establishing young forests. Two years ago I called your atten-
tion to an insect then recently discovered by Prof. A. R. Grote, of Buffalo, which was
greatly injuring the terminal shoots of both the white and red pines in Western Ney
York; it was the larva of a small moth, Nephopteryw Zimmermani, which fed under the
bark, causing a free exudation of resinous matter from the wounds it made, followed
usually by the death of the twigsinfested. Since then it has been found over a much
wider area than was at first anticipated, and I have no doubt but that it is to-day ma-
terially retarding the growth of young pine trees in many portions of our Province.

At arecent meeting of the Kntomological Club of the American Association for the
Advancement of Science (where our Society was represented by your President and
Vice-President), Mr. 8. H. Scudder, of Boston, submitted some observations on another
lepidopterous insect which is injuring the young pines growing on the Island of Nan-
tucket. It is a species of Retinia closely allied to Retinia duplana of Europe. The moth
lays her eggs near the tips of the twigs, down which the young larve burrow, killing them
outright, and thus stunting and almost destroying the trees. Prof. Comstock, of Wash-
ington, also referred to two other species of Retinia which he had observed injuring the
pine trees in that city.

In addition to all these, there are a score or two of species of insects which are known

to devour the leaves of the pines, damaging them in some instances very much. From
the facts enumerated it is evident that we are suffering serious loss in all our lumber-
ing districts from the silent workings of these insidious foes, and since in some measure
to be fore-warned is to be fore-armed, I desire to call the special attention of those im-
mediately concerned in the prosperity, present and future, of the lumbering interests of
our country, to this important subject. Unfortunately it does not as yet seem to be
within the power of man to do much directly towards restricting the operations of these
enemies to our forests; yet this should not deter us from studying their habits and his-
tory, since an intimate acquaintance with these may result much more to our advantage
than we now anticipate. A few trees, such as a belt, or a group planted for shelter or
ornament, may be protected from the leaf and twig destroyers by syringing with a mix-
ture of Paris Green and water in the proportion of a teaspoonful to a pail of water, and
the bark lice may be killed by the use of alkaline washes applied with a brush or broom,
and a timely application of the same will prevent the operations of the borers; but itis
scarcely possible that such remedies can ever be applied over extended areas of forest.
It is, however, gratifying to know that in addition to the numbers devoured by our in-
sectivorous birds, almost every injurious species is in turn attacked to a greater or
less extent by insect parasites of the most active habits, who seek out and destroy these
pests with ceaseless diligence ; were it not for these friendly insects the destructive spe-
cies would be far more numerous individually than they now are. ;

The question as to how best to check the increase of destructive insects is of the
greatest practical importance, and probably no insecticide has of late played so import-
ant a part in this connection as Paris Green, which is a compound of arsenic and cop-
per, comparatively insoluble and a substance which seems admirably qualified for the
destruction of insect life. Besides its special use as a potato-beetle killer, it can be suc-
cessfully used to destroy any and every insect which eats the leaves of plants, shrubs or
trees. So poisonous an agent should be handled with caution if accidents are to be pre-
vented, and it is a matter of great regret that in consequence of carelessness in its use
the lives of many valuable animals have been sacrificed, and occasionally even human ~
lives have been imperilled or lost. From the ease with which it can be procured it has
also been resorted to in several instances by those determined on suicide. These unfortu-
nate occurrences are greatly to be deplored, and every possible precaution should be taken
to avoid accidents. It is quite a common occurrence for painters, hardware dealers and
general merchants to sell Paris Green and to send it out without label of any sort, and
sometimes the parcel is very insecurely put up and packed with groceries and
other articles for home use in the most indifferent manner. Such recklessness should
not be permitted and no one should be allowed to sell any substance so dangerous un-
less itis properly labelled with the name of the article and the word ‘‘ Poison” promi-
nently attached; with such precautions generally adopted many accidents which now
occur would be prevented. It has been urged by some that so many evils have attended
the use of Paris Green that it does more harm than good, and that its use should be
discontinued ; but in this I am not prepared to concur, as I am satisfied that without it,
unless some suitable substitute were found, the potato crop in many localities could not
be preserved from destruction. If reasonable care is exercised and the powder be used
mixed with water, there is no danger attending it, and its use in this manner in the pro-
portion already mentioned of a teaspoonful to a pail of water and applied with a whisk,
is not only safe but most economical.

For some years past experiments have been made with various other substances
with the view of finding a substitute for Paris Green which would be less dangerous in
the hands of the careless, and among them I believe none have been used with greater
success than common blue vitriol or sulphate of copper, in solution in the proportion of
about an ounce to a pail of water, and applied in the same manner as the Paris Green
mixture. This article is worthy of, and will doubtless receive, a more extended trial, as
its use under any circumstances would be attended with but little danger. For the de-
struction of household pests Insect Powder has lately attracted much attention, and is
probably the most valuable agent we have for this purpose, and it is quite harmless to
man and the higher animals. There are two sorts of this powder, known in commerce

= ee —

under the respective names of Persian and Dalmatian Insect Powder; the former is the
powdered flowers of Pyrethrum roseum, the latter of Pyrethrum cinnerariafolium. The
Dalmatian Powder is most highly esteemed. The powder is diffused through the atmos-
phere by means of a small bellows, or insect gun, and in a very short time it brings house-
flies, cockroaches, etc., on their backs, and dusted among bed-clothing is equally effec-
tual on noxious peststhere. It does not at first kill the insects outright, but paralyzes
them so that they are unable to use either legs or wings, and after remaining in this
condition many hours and sometimes days, a solitary mdividual here and there will
either wholly or partially recover, but the great bulk of them die.

A very active blue-bottle fly placed under the influence of the powder was brought
-onits back in one and ahalf minutes. After six minutes it performed some remarkable
evolutions, throwing itself about in the most desperate manner by the aid of its wings,
for by this time it had lost the use of its legs; in a few moments more it was quiet, but
still able to move its legs, and this power it retained for two days, after which it was lost
sight of. The same powder was applied to a full-grown grasshopper; immediate un-
easiness was manifested, and within two minutes its hind legs were partially paralyzed
so that they could not be used with much effect. The first symptoms were a general
rubbing of the legs against each other and a peculiar backward movement of the body ;
in four minutes there was a trembling of the whole frame, while all the legs were so
much affected that locomotion was very feeble. In six minutes the insect’ had lost all
control over its limbs, and in nine minutes it was on its back, with no power to recover
its natural position. A second patient manifested precisely similar symptoms, but was
‘not affected quite sorapidly. Applied to house-flies in a room, some of them begin to
fall powerless in two or three minutes ; others will remain active several minutes longer,
but manifest constant uneasiness, evidenced in unnatural movements of wings and legs,
and a frequent thrusting out of the proboscis. Having operated in aroom one day about
noon, I swept up after a few minutes several hundred flies and put part of them in a
tumbler covered witha small plate, and the remainder ina chip box which I carried in
my pocket for the first day, where the flies would receive some warmth from the body.
After five or six hours the box was opened, when several crawled out or flew with a very
weak, short flight ; these were evidently recovering ; the others remained on their backs,
many of them moving their legs now and then. At the same time those in the tumbler
were looked at; all were on their backs, but still alive. In twenty-four hours after-
wards those in the glass were in the same helpless condition, barely alive, while in the
box three more had so far recovered as to be able to walk, and one of them could fly a
little. The following day they were examined again and every one of those in the box
were dead, while in the tumbler, out of 137, there were 22 alive, which number was
reduced to three the following day; this small remnant survived two days longer, when
all died.

In the use of Insect Powder on the green Aphis, which infests house plants, the
same course was observed; the insects dropped from the plants as if paralyzed, and
after a short time were incapable of locomotion. After two days they were found still
alive, but in this instance there was no sign of recovery in any of them, and all died
within two or three days afterwards, but whether from the direct effects of the powder or
from starvation I was unable to decide.

When I addressed you last year I referred to a strange disease which had destroyed
large numbers of that destructive pest, the Forest Tent Caterpillar, Clisiocampa sylwat-
ica. After the disease had reached a certain stage the larve remained motionless, re-
taining their hold on fences and the trunks of trees; shortly, although in appearance
‘they were quite natural, when touched they were found to be dead, and their bodies were
so decayed as to burst with a very gentle handling. Subsequent observations convinced
me that this was the result of a fungoid disease to which caterpillars, as well as some
perfect insects, are very subject. A similar disease sometimes attacks the silk-worm
and causes great devastation, and the common house-fly is liable every autumn to die
from the effects of a fungus which multiplies with amazing rapidity within the fluids of
the fly’s body, soon destroys life, and forms a circle of Juxuriant growth all around its
victim. Examples of this may be found on the windows of almost every dwelling during

the month of September. Some years agoa learned European professor claimed that
he had proved the identity of this fungus with the common blue mould and also with
that of yeast; and in proof used the fungus of the fly for the purpose of raising bread,
and shewed that it was possible to brew beer with the common mould. The close re-
lationship, if not the actual identity, of these three was thus established. Quite recently
it has been proposed by Dr. Hagen, of Cambridge, Mass., to use a diluted solution of
yeast in water with an atomizer as a means of destroying noxious caterpillars and other
insects by introducing disease among them, and it seems quite likely that the use of this
remedy may to some extent prove effectual.

The Cabbage Butterfly, Pieris rape, having pretty well colonized the northern por-
tions of America, is still travelling southward. During the present season it has been
reported as common in many localities in the State of Alabama, and has nearly reached
the Gulf of Mexico; it seems as capable of adapting itself to extremes of heat as of cold.
The Forest Tent Caterpillar, Clisiocampa sylvatica, which has been so very numerous and
destructive in our neighbourhood for two years past, has almost disappeared. The Col-
orado Potato Beetle seems to have fairiy established itself in several places in Europe,
and if it proves as prolific there as here it will be rapidly disseminated. The Wheat
Midge, Oecidomyia tritici, has appeared in the neighbourhood of Port Hope, Ont., but not
to any alarming extent. The Plum Curculio, Conotrachelus nenuphar, has been common
as usual, while reports have been received from several districts of the increasing preva-
lence of the Codling Worm, Carpocapsa pomonella.

Our journal, The Canadian Entomologist has been well sustained during the past
year, and through the kindness of our esteemed contributors we have been enabled to
present our readers with many original papers of great practical value. Mr. W. H.
Edwards, of West Virginia, has continued his very useful and valuable papers on the life
histories of our butterflies. Dr. Bailey, of Albany, N. Y., has given us an interesting
description of the various stages of Cossws Centerensis, illustrated by an excellent litho-
graphic plate. Many new species of insects have been described by Messrs. A. R. Grote,
W. H. Edwards, V. T. Chambers, Prof. Fernald and others, besides which we have pub-
lished a very large number of papers of general interest.

Among the more important recent contributions to our Entomological literature may
be mentioned a new edition of the Catalogue of the Described Diptera of North America,
by Baron Osten Sacken; the Coleoptera of Florida and Michigan, by John L. LeConte,
M. D., and E. A. Schwarz; Report on the Insect and other Animal Forms of Cale-
donia Creek, New York, by J. A. Linter; the Coleoptera of the Alpine Regions of the
Rocky Mountains, by John L. LeConte, M. D.; on the Collection of Insects made by
Dr. Elliot Coues in Dakota and Montana—the Orthoptera by Cyrus Thomas, Hemip-
tera by P. R. Uhler, Lepidoptera by W. H. Edwards; Notice of the Butterflies Collected
by Dr. Edward Palmer in Southern Utah and Northern Arizona, in 1877, by Samuel H.
Scudder; and an account of some insects of unusual interest from the tertiary rocks of
Colorado and Wyoming, by the same distinguished author. The elaborate and volumi-
nous report of the U, S. Entomological Commission on the Rocky Mountain Locust, with
maps and illustrations, issued in 1878, did not reach us in time to be noticed at our last
annual meeting. It is a work which has involved great labour, and besides containing
much thatis new, covers the entire field of our knowledge in reference to this destructive
pest. Prof. C. V. Riley, of Washington, has issued a special report on the Silk-worm,
being a brief manual of instructions for the production of silk, with illustrations. Prof.
A.R. Grote has written Preliminary Studies on the North American Pyralide, and
Samuel H. Scudder a Century of Orthoptera. Several additional numbers of Edwards’
magnificent work on North American Butterflies have appeared, with charming plates.

The members of the Entomological Commission of the United States are devoting
their attention this year especially to the Hessian Fly, investigating its habits, preparing
statistics of the losses occasioned by its attacks, and testing the various remedies which
have been suggested for its destruction. In a circular issued in June last they solicit the
co-operation of Hntomologists, many of whom will, I trust, be able to render them
efficient aid in this good work.

During the year, death has removed from our ranks three well known labourers in

the Entomological field, Dr. Asa Fitch, late State Entomologist of New York ; Dr.
Hermann Loew, the eminent German Dipterist, who has done so much to advance our
knowledge of American Diptera; and Frederick Smith, the renowned English Hymen-
opterist. Thus, year by year, we are called to mourn the loss of those whose names, for
their works’ sake, we revere. They have gone to their reward; we live to labour. Let
us each endeavour to make the best possible use of the time and opportunities we have,
however limited they may be, and dilligently and contentedly labour in the sphere in
which God has placed us; prompted by pure motives, may we with earnest effort probe
deep into the secrets of nature, and draw from thence treasures new, so that when we
pass away, we may leave behind us some little lustre which may lend a light, however
dim, to those who will fill our places.

I have the honour to be, very sincerely yours,
Wa. SaunvErs.

mens of some of our large Butterflies and Moths as models for the drawing and painting
classes, which was cheerfully granted.

Mr. Saunders gave an interesting account of his recent visit to Florida, and
exhibited some of the insects obtained by him while there.

10

Mr. H. B. Bock kindly presented the Society with a number of specimens of
Coleoptera from Germany.

Subsequently an hour or two was spent in social intercourse and participation in
the many means for enjoyment provided by Mr. Denton for the members. After spend-
ing an exceedingly pleasant evening the meeting adjourned.

MONTREAL BRANCH OF THE ENTOMOLOGICAL SOCIETY OF ONTARIO.

The Sixth Annual General Meeting of the Montreal Branch of the Entomological
Society of Ontario was held at the residence of G. J. Bowles, Esq., on Tuesday the 3rd
June, 1879, at 8 o’clock p.m.

Mr, Bowles read a paper entitled, ‘‘Some of the insects that frequent the orchard
and garden, under what circumstances they increase unduly, what insects to spare,
what to kill, and how to kill them, with other useful information,” by the Rev. F. W.
Fyles, corresponding member of the Natural History Society.

The annual report of the Secretary-Treasurer was then read and adopted. This
report shewed that after meeting the current expenses of the year, there still remained
a very fair balance on hand.

_ The proceedings were closed by the election of the following officers for the ensu-
ing year :— .

President, G. J. Bowles; Vice-President, H. H. Lyman; Secretary and Treasurer,
Geo. H. Bowles; Curator, F. B. Caulfield ; Council, Robert Jack, W. Couper and G. B.
Pearson.

The meeting then adjourned.

ANNUAL REPORT OF THE COUNCIL OF THE MONTREAL BRANCH OF
THE ENTOMOLOGICAL SOCIETY OF ONTARIO.

In presenting their Sixth Annual Report, your Council have much pleasure in
stating that the Society is still making satisfactory progress.

Eight very pleasant meetings have been held during the year, and besides the
many interesting Entomological items recorded in the minutes of the Society, the
following papers have been read before the members :—

1. ‘On the Larve of Papilio Brevicauda and Pieris Borealis, and the food plants.”
—W. Couper.

‘“On the May beetle, Zachnosterna quercina, and its parasites.’’—G. J. Bowles.
. *Tutroductory notes on the Ichneumonidae.” —G. J. Bowles.

. “On the Saw-flies.”—G. J. Bowles.

. “My Entomological] trip to the Godbout River, 1878.”—W. Couper.

. ‘On the Insects otf the Mammoth Cave” (selected).—Geo. H. Bowles.

The following books have been added to the Library :—

‘“‘Riley’s Reports,” 2,4 and 5, making the set complete. The nine reports have
been bound in three volumes, and form a very valuable addition to our library.

‘‘ Hentz’s Spiders of the United States,” with 21 plates.

‘‘ Sausser’s Solitary Wasps of America,” with 4 plates.

‘“* La Crysomele des Patates,” from the Department of Agriculture, with 1 plate.

‘Reports of the Fruit Growers’ Association of Montreal, 1877 and 1878.”

AA NAP oo po

< > eT ae — == SS eo

Our order for books to the Naturalists’ agency is still not quite filled, and a balance
of about $10 remains in their hands.

Your Council would note that additions are still being made to the list of species
in the ‘‘ Montreal Catalogue,” and would recommend the work to the members as one
worthy of zealous prosecution.

In regard to the labours of the coming season, your Council feel glad to report that
the members are beginning their collections with renewed vigour; and they trust that
the next year’s operations will show a great advance in the study of our fascinating
science in Montreal.

The whole respectfully submitted,

MEETING OF THE ENTOMOLOGICAL CLUB OF THE AMERICAN ASSOCI-
ATION FOR THE ADVANCEMENT OF SCIENCE.

The Annual Meeting was held, as announced, on the 26th day of August, in the
Town Hall, in Saratoga, N.Y. The first session began at 12.30 p.m., the President, J.
A. Lintner, of Albany, in the chair. The following members were present during the
several sessions: Dr. John L. LeConte, 8. H. Scudder, C. V. Riley, A. R. Grote, C. H.
Fernald, Dr. John G. Morris, Rev. C. J. 8. Bethune, Wm. Saunders, J. H. Comstock,
EK. P. Austin, F. W. Putnam, B. P. Mann, H. F. Bassett, W. S. Barnard, D. 8. Martin,
K. L. Graef, Dr. J. S. Bailey and E. H. Pohlman.

The Secretary, Mr. B. P. Mann, read the minutes of the last meeting in St. Louis,
Mo., after which the President delivered the following address :—

ANNUAL ADDRESS OF THE PRESIDENT.

GENTLEMEN :—In the remarks which I presented to the Club at our last annual
meeting, a brief review was given of the progress in American Entomology within the
preceding half century. It was shewn that within the last few years rapid progress
had been made; that the study of insects had enlisted the labours of many earnest and
successful workers, and given to them names honoured in science both at home and
abroad ; that many large and valuable collections had been accumulated—several of
which contained so large a number of types that their preservation in the future was a
matter demanding serious consideration ; that the literature had become quite exten-
sive ; that much had been done in working out the life-histories of our species and pre-
senting them to the public in their economic relations; and finally, that the importance
of the study had at last been recognized here, as long ago it had been in Europe, by a
Commission appointed by our General Government, for the investigation of some of the
insect pests which were the occasion of serious pecuniary loss, poverty, and almost star-
vation in some portions of our country.

It affords me pleasure to be able to report, that the past year has shewn no
diminution of interest or activity in our department, but that work in it is being
prosecuted with an energy and with results fully up to any other department of Natural
Science, if we except those to which Congress and several of our States are extending
their liberal aid. ‘

If fewer new species have been described during the year, we may find encourage-
ment in the explanation that we are approaching the period, if not already reached,
when a new species may not be claimed as the reward of every Entomological excur-
sion. And indeed, there does not seem to be urgent need of descriptions of forms so
very far in advance of some degree of knowledge of transformations, habits and relations
to the vegetable world.

_ _ An evidence of increasing interest is to be found in the frequent inquiries made for
instructions in collecting, apparatus for preparation, and books for study. While the
first two requests can be promptly met, not so with the last. We are unable to place

12

in the hands of the student the volumes which he requires for naming his collections.
This cannot but be the occasion of discouragement to the beginner, and often the cause
of diversion of earnest labour to other departments of Natural History. A great need
of our science at the present is, monographs of the families prepared by specialists, in
which descriptions of all the species shall be given (not simply referred to), and accom-
panied by such synoptical tables and illustrations as will enable the student readily to
ascertain the names of any species which has been described.

At our last meeting I stated to you that the names of 281 persons are recorded in
the last edition of the Naturalists’ Directory who are making Entomology their study in
North America, and that it was probable that a full list would extend the number to at
least 3850. It now appears that half the truth was not told. A list kept by the Secretary
of the Cambridge Entomological Club, published in Psyche, vol. ii., p. 9 of Advertiser,
accompanying the numbers for Sept.-Dec., 1878, contained at the close of last year the
names of 762 Entomologists in the United States and Dominion of Canada. I am in-
formed by the Secretary thai the list at the present time, without having been subjected
to a critical revision, contains 835 names.

As a record of the current literature of any science is virtually a record of the
progress of that science, may I ask your attention to a brief notice of some of the
publications of the year following our St. Louis meeting.

A work that might serve as a model in the illustration of insects in their relations
to the plants upon which they feed or frequent, is one of the unique series by Mr. Glover
of Manuscript Notes from My Journal, entitled, ‘‘ Cotton, and the principal Insects
frequenting or injuring the plant.” In its twenty-two quarto plates, engraved on copper,
is shown the cotton plant in every stage of development from the seed to the mature
plant, and in its various conditions as resulting from insect attack or from disease. In
association with these figures, twenty-four insects frequenting the plant are represented.
Several of the species are illustrated in an agreeable prodigality, giving enlarged views of
the egg, the larva at different stages of growth, the pupa, the cocoon, the perfect insect
at rest and in flight, its under surface, enlargements of parts, and the more marked
varieties of the larva andthe imago. Although not so stated, it is believed that the
edition of these Notes was no larger than the others of the series, and consequently,
that only about fit:y societies and individuals have been the fortunate recipients of
a copy.

The Natural History of the Agricultural Ant of Texas is avolume of 208 pages and
24 plates, by H. C. McCook, treating at length of the habits, structure and architecture
of this interesting insect. The histological details have been worked out from prepara-
tions made by Prof. J. G. Hunt.

A volume, upon which Baron Osten Sacken has been for a long time engaged, has
recently been completed and published by the Smithsonian Institution. The Catalogue
of the Diptera of North America prepared by this author and published in 1858 was
simply a compilation of published names, not claiming synonymic accuracy. It con-
tained 1,800 species, but many of the number were too imperfectly described for identifi-
cation. The new Catalogue is of such merit as to deserve more than a passing mention.
It is fully up to, and in itself materially advances, our knowledge of the Diptera of our
country. Its author modestly regards it as only critical in part—so far as the families
have been worked out into monographs, and as still remaining a mere list of reference
to earlier writers, in those families which have not been studied, or in which the existing
collections are to a great extent still unnamed, as in the Culicide, Chironomide, Cenopide,
the group of Muscide calyptere, and the section Asilina. Its critical character may be
seen from the statement, that of the 102 species of Tabanus enumerated in the old Cata-
logue, only 36 have been adopted in this.

An admirable feature of this Catalogue is that a large proportion of the species
which it records—over 2,000 carefully described and authoritatively labelled species—
are contained in the Collections of the Museum of Comparative Zoology at Cambridge,
fwhere every possible care is given to them, and where they are accessible to the student
or comparison and study. Most of these are types of Loew and Osten Sacken, or their
determinations.

13

The remarks of the author on synonymy, nomenclature and priority, seem to me to
be most excellent and worthy of serious consideration. In an extended discussion
of the merits of the descriptions of Diptera of the late Mr. Walker of the British
Museum, he characterizes them as so extremely superficial—descriptive rather of the
specimen than of the species, that in his opinion, they should be entitled to no claim for
priority whenever they cannot be positively identified without an examination of the type
specimen. Thus, of twenty-six species of Dolichopus described by him, not a single one
could be recognized. The question suggests itself, to what extent might this rule be
extended to descriptions in the other orders of insects by this author, and in general, to
the writings of other authors.

In considering the number of Diptera, Osten Sacken believes, that rejecting those
descriptions which will probably prove irrecognizable, the number of described Diptera
of North America, north of Mexico, will hardly reach 2,500; that the undescribed
material at present in collections, if worked up, would perhaps double the number; and
that when the long neglected order shall have received the attention given to the Coleop-
tera, it will equal if rot exceed the latter, numerically.

Reference at the present to studies in the Diptera, naturally suggests the great loss
which Dipterology has sustained in the recent death—in April last—of the distinguished
Prussian Dipterist, Dr. H. Loew, long known as one of the most eminent cultivators of
this branch of Entomology. During the last twenty years he has been engaged in the
study of North American Diptera, and at the request of the Smithsonian Institution he
has prepared a series of monographs, three volumes of which (Parts i., ii. and iv.) have
been published by that Institution. While hisremoval from his work at this stage of its
progress, cannot but be deeply deplored, there is a consolation to be found in the know-
ledge that it is not to be wholly arrested, but that a worthy collaborator—Baron Osten
Sacken—remains to conduct it to a completion, we hope, of the plan proposed.

The series of Dimmock’s Special Bibliographies, now being published at Cambridge,
Mass., will prove to be of eminent service to the student who desires to avail himself of
the literature of our insects, so widely scattered through the various scientific and popular
journals, government surveys, and other publications. ‘Two numbers of the series have
been issued—the first containing a complete list to date, it is believed, of the Entomo-
logical writings of Dr. John L. LeConte, and the second, those of Dr. George H. Horn.
A third, of the writings of Mr. 8. H. Scudder, is nearly completed. I regret that it has
been thought necessary, in this series, to dispense wholly with the use of capitals in ail
scientific names, even in the family and ordinal divisions, and I believe that many of you
will agree with me in claiming for the royalty of science exemption from conformity to
an innovation based on mere convenience.,

Prof. C. V. Riley and J. Monell have contributed to the Bulletin of the U. S.
Geolog.-Geograph. Survey (vol. v., pp. 1-32) a paper entitled Notes of the Aphidide of the
United States, with Descriptions of Species Occurring West of the Mississippi. Part I con-
tains extended biological notes on the Pemphigineg, by Prof. Riley, and Part II., notes on
Aphidine with descriptions of new species, by Mr. Monell. The paper, illustrated by two
plates,is a valuable contribution to our knowledge of these exceedingly interecting insects.

A special Report from the Department of Agriculture, entitled, The Silk-worm, being
a brief Manual of Instruction for the Production of Silk, has been prepared by Prof. Riley,
and largely distributed by the Department, to meet the demand from various portions of
the United States for information upon the important industry of silk-culture. The
Manual is quite full inthe natural history of the Silk-worm, in the methods of culture,
and directions for reeling the cocoons. There seems no reason why this industry,
properly fostered, may not be made to add materially to the productive resources of our
country.

Abstracts of the papers presented by Prof. Riley at the St. Louis meeting of the
American Association for the Advancement of Science, have been published in the Pro-
ceedings of the Society, and also in a separate pamphlet. Among these are Notes on
the Life-History of the Blister Beetles and on the Structure and Development of Hornia ; on the
Larval Characteristics of Corydalus and Chauliodes, and A New Source of Wealth to the
United States [Sericulture]. ‘

14

A Century of Orthoptera, commenced by Mr. 8. H. Scudder in 1868, and continued
at intervals in vols. 12-20 of Proc. Bost. Soc. Nat. Hist., has been completed during the
present year by the publication of the last three decades, in vol. 20, op. cit. The species
described pertain to the Gryllides, Locustarie, Acridii and Forficularie. The several
parts as originally published have been reprinted in a pamphlet of 84 pages. Mr.
Scudder has also published (Psyche, vol. u., p. 154) a short list of Orthoptera collected in
Appalachicola.

Entomological Notes, No. vi., by Mr. Scudder, issued the past year, is mainly a
reprint of papers upon the Orthoptera originally published in the preceding year. The
accompanyingindex furnishes a ready means of reference to the species contained in the
several papers.

In the Annual Report of the Chief of Engineers for 1878, Prof. Cyrus Thomas
reports upon a small collection of Orthoptera made in the Explorations and Surveys of
the San Juan region of Colorado. The same volume contains a report by Mr. H. Strecker,
on the Hymenoptera, Lepidoptera and Coleoptera from the same region, in which several
new species of Heterocera are described, and a few figured.

Of our Entomological serials, the Canapian Entomonocist continues to sustain its
high reputation, and to merit the contributory aid which it is receiving from nearly all
of our American Entomologists, and from some of our European friends,

Psyche, the organ of the Cambridge Entomological Club, is near the completion of
its second volume. With the commencement of its third volume such improvements
are promised as will render it of still higher importance to every student of American
Entomological literature.

The Transuctions of the American Entomological Society have reached the seventh vol-
ume. Although the Society has become a section of the Academy of Natural Sciences
of Philadelphia, it is proposed to continue the publication of the Transactions as at
present as rapidly as the‘limited means available for the purpose will permit.

The Bulletin of the Brooklyn Entomological Society is contmued. That of the Long
Island Society has been discontinued.

The second volume of the Butterflies of North America, by Mr. W. H. Edwards, is in
course of publication. It continues to maintain the high reputation which it has com-
manded, from its admirable delineations of forms and colouring, and the exceedingly
interesting new biological details presented.

The North American Entomologist is a new candidate for favour and support, of
which two numbers have appeared. Itis a monthly periodical, published at Buffalo,
N.Y., under the editorial charge of A. R. Grote. It purposes to present articles of value
both to the specialist and the agriculturist on the subject of North American insects, to-
gether with notices of current entomological literature,

Descriptions of the Noctuide have been continued by Prof. A. R. Grote in contribu-
tions to the Canapian Entomotocist and in the North American Entomologist. With a
diminution in the number of new forms of Noctue presenting themselves, Mr. Grote has
directed his attention to the Pyralide, and has published a paper in the Bull. U. S.
Geolog.-Geograph. Survey (vol. iv., pp. 669-705), entitled, A Preliminary Study of the
North American Pyraiide, in which a number of new species are described, the species
of Botis enumerated, and the venation given of certain genera of the Phycide. A sup-
plement to this paper follows in the North American Entomolovist, No. 2, pp. 9-12.

To the study of the Tortricide—a family which has received scarcely any attention
in this country since the death of Mr. C. T. Robinson, Prof. C. H. Fernald, of Orono,
Me., has been devoting special and earnest attention. He has been able to examine
nearly all the material contained in the principal collections in this country, and during
the past winter has visited the larger collections in Europe for their study and a com-
parison with our forms. In England, the Tortricide in the following collections were
critically examined by him: those of the British Museum, of H. T. Stainton, R.
McLachlan, C. J. Barrett and Lord Walsingham ; and on the continent, the collections in
Brussels, Berlin, Munich, Naples, of Prof. Zeller in Stettin, Dr. O. Staudinger, MM.
Deyrolle and Ragenot and the Jardin des Plantes in Paris. The above amount of pre-
liminary work should certainly enable Prof. Fernald, as is his hope, to present us with

\

a rearrangement of this extensive family quite in advance of any heretofore proposed.
Prof. Fernald has prepared a synonymical list of our North American species, which is
nearly ready for publication.

The work of Mr. V. T. Chambers on the Tineide of the United States, has been
vigorously prosecuted, as may be seen in his frequent publications in the Canapran En-
TomoLocist. His paperson Tineina and their Food-plants, and Index to the Described
Tineina of the United States and Canaaa (Bull. U. 8. Geolog.-Geograph. Sury., vol. iv.,
pp. 107-167), have been appreciatively received as very convenient for reference.

The comparatively small but difficult group of the Pterophoride has engaged the
attention of Mr. Charles Fish, of Oldtown, Me., and his studies have already made him
our best authority in these forms.

From the above references to special studies in several of the families of the Lepid-
optera, it will be seen that this attractive Order gives every promise of soon occupying
high vantage ground.

In the other Orders—it is quite unnecessary that I should refer in the Coleoptera
to the labours of Drs. LeConte and Horn. You will know of their untiring work,
which has made the field which they are so thoroughly working almost exclusively
their own.

In the Diptera, Mr. C. P. Whitney has published descriptions of a few species of
Tabanide.

Mr. W. H. Patton has communicated some descriptive papers on Hymenoptera to
the Canap1an Enromotoaist.

Mr. E. T. Cresson has pnblished a catalogue of North American Apide, with de-
scriptions of new species, comprising 108 pages of vol. vii. of the Trans. Amer. Ento-
log. Soc.

Some valuable lists of species collected in particular regions have been given us,
which are of service in extending our knowledge of Geographical Distribution. Among
these, in the Coleoptera, may be mentioned, a list by EH. A. Schwarz of 1,457 Florida
species (Proc. Amer. Philosoph. Soce., v. 17, pp. 858-472) ; of 1,246 species from the Lake
Superior region by H. C. Hubbard and E. A. Schwarz; by the same, of 1,787 species
from the lower Peninsula of Michigan (loc. cit., v. 17, pp. 593--666); by Dr. LeConte, of
220 species collected in the Rocky Mountains at an elevation of 6,000 feet and upwards
(Bull. Geolog,-Geograph. Surv. Terr., v. 4, pp. 447-480); additions to Messrs. Austin
and LeConte’s Catalogue of the Coleoptera of Mt. Washington, of 89 species, extending
the number to 319, by F. Gardiner, jr. (Psyche, v. 2, p. 211); 316 species from Wallace
Co., Kansas, by F. H. Snow (Trans. Kans. Acad. Sci. vol. vi., pp. 61-70) ; and additions
of 485 species to the Catalogue of Kansas Coleoptera, by H. A. Popenoe (ut. cit. pp. 77-
86), increasing the number to 1,711.

In the Lepidoptera, Mr. C. EK. Worthington furnishes a list of 229 species of Noc-
tuide from the vicinity of Chicago, Ill., (Canad. Entomol., v. xi., p. 68); Mr. W. L.
Devereaux, a shorter list of species taken in Wayne Co., N. Y. (ut. cit., p. 105) ; Prof. F.
H. Snow, a list of 104 species collected in Colorado, by the Kansas University Scientific
Expedition in 1876.

The valuable biological studies of Mr. W. H. Edwards have been continued with
their wonted earnestness. Through the success attained by him in carrying a large
number of species of butterflies from the egg through their transformations, he has
secured their entire life-histories, several of which have been published during the past
year, and othersillustrated in the volume of the Butterflies of North America. Of the
Satyride, the larva of which are so rarely met with that 1 may venture to say many
members of this Club have not seen a living example, he has reared all of our Hastern
species with the two exceptions of Satyrus Pegale and Chionobas semidea. The interesting
experiments in producing change in the imago by the application of cold to the chrysalis
have been continued and been duly recorded.

A large number of biological papers have been contributed to our Entomological
journals. From those accessible to me at the time of writing I find contributions from
the following :—C. J. 8. Bethune, J. Boll, Robert Bunker, V. T. Chambers, A. J. Cook,
Charles Dury, H. Edwards, W. H. Edwards, J. H. Emerton, G. H. French, H. A.

S. Westcott, C. EH. Worthington, and G. D. Zimmerman—a quite incomplete list of the
contributors to this department.

Results of anatomical studies of insects have been published by Messrs. C. F.
Gissler, J. D. Hyatt, KE. L. Mark, and C. V. Riley.

It would be inexcusable in a notice of biological work to omit reference to what is
being done in this direction at the Museum of Comparative Zoology at Cambridge.
Under the hand of the eminent Curator of the Entomological Department, Dr. H. A.
Hagen, a biological collection of insects has been brought together that is far im advance
of any similar collection in the world. It was my privilege recently to give it a partial
examination, and when I say that I know not how to express my high estimation of it,
I give it but imperfect praise. No one, whose studies have prepared him for the appre-
ciation of such a collection, can examine it without wondering when, where and how
the material was obtained. As an illustration of the natural history of species in their
several stages, architecture, depredations, food-plants, diseases, parasites, etc., it is
difficult to see how its plan of arrangement can be improved. In consideration of its
high value, it is very gratifying to see that such unusual means have been resorted to
for its preservation, as, with a reasonable supervision and without the operation of
other than the ordinary causes of destruction, will extend its benefits to our successors
in coming centuries. In addition to the biological collection, two others have been
arranged: the one comprising the insects of North America, and the other those of the
world. Of the number of type specimens contained in these collections, there is not
the time at present, nor is it the occasion, for more than simple mention. The student
in American Entomology, who aims to be fully abreast of the most advanced progress
in his line of study, cannot neglect the means of information which the Collections and
Library of the Entomological Department at the Cambridge Museum offer him.

The published results of economic investigations during the year have been quite
limited. In consideration of the exceeding importance of these studies, it is painful to
have to record the fact of the issue of but one Annual Report of a State Entomologist
—that of Cyrus Thomas. This second report of Dr. Thomas, forming the seventh in
the series of the [linois reports, is a volume of nearly 300 pages. In it Dr. Thomas
discusses the depredations of some of the Orthoptera, Coleoptera and Hemiptera.
Prof. G. H. French, Assistant Entomologist, presents brief descriptions of a large
‘number of diurnal and nocturnal Lepidoptera and their larve, with notices of their
habits, accompanied by analytical tables for their identification. Miss Emma A.
Smith, special Assistant Entomologist, offers the results of original investigations in
some species of special economic importance. The publication of this and the preced-
ing Report, without, as is evident, the opportunity of the revision and correction of
proof by the authors, is much to be regretted, as serious errors in the nomenclature
and elsewhere have thereby been given extensive circulation.

The Annual Report of the Entomologicai Society of Ontario, making the ninth in
the series, contains its usual amount of matter of interest to the Entomologist, and of
value to the agriculturist and. horticulturist.

Several articles treating of insect depredations have appeared in our scientific
journals, which cannot now be referred to.

The United States Entomological Commission, continued by an appropriation by
the last Congress of $10,000, is actively engaged in its second year’s operations. In
its investigations of the Rocky Mountain Locust, its labours have been almost entirely
confined to that portion of country designated as the Permanent region, with a view of
determining the limits of these permanent breeding grounds, and to obtain the requisite
data for the preparation of a map, and a scheme to be recommended to the Govern-
ment, by which the excessive multiplication of the species in that region, and the
consequent migration therefrom, may be prevented. It is understood that the recom-
mendation to the Government will be, that in connection with the authorities in British
America, efforts be made to restrain the extensive prairie fires in autumn which are
common to that region, and subsequently to burn them in the spring after the hatching

\

17

of the young locusts. This plan is believed to be feasible, as the breeding grounds are
not co-extensive with the so-called Permanent region, but are limited to the richer
valleys, plateaus and river borders within it.

The Commission will also, it is understood, in its forthcoming report, recommend
to the Government a scheme for a system of warning and prevention, through the aid
of the mounted police patrol of the Dominion Government, and our signal bureau and
military posts.

Having been favoured with a transcript of the subjects to be treated of in the
forthcoming Second Report of the Commission, and the assignment of subjects to the
respective members of the Commission, I have no hesitancy in giving assurance of a
volume of unusual interest and value. It is to be hoped that Congress will not repeat
the inexcusable blunder of ordering of it an edition by far too small to supply the
demand, or for the accomplishment of a main object in its labourious preparation—the
diffusion of the needed information among those to whom it could not fail of proving
beneficial.

The Commission is also occupied with investigation of the Hessian-fly and the
Chinch-bug—each of which are chargeable with annual injuries to the amount of
several millions of dollars.

The investigation of the natural history and habits of the Cotton-worm, com-
menced by the Department of Agriculture last year, has by direction of Congress, been
transferred to the Entomological “Commission. Prof. Riley has been pursuing its study
in Southern Texas and in the Gulf States, aided by special assistants, and it is believed
that discoveries have recently been made which will reduce the cost of destroying the
larve to perhaps a fourth of what it has hitherto been.

Among the special subjects of study which have claimed attention lately, an inter-
esting one has been the pupation of butterflies. Observations made during the past year
on the pupation of some of our butterflies have shown us that we have been at fault in
accepting the account given ofit by Reaumur over a century ago, and received and quoted
by subsequent authors. The most interesting operation iu the pupation of the suspensi
butterflies is the withdrawal of the chrysalis from the larval skin, the casting off of the
skin with its attachment by the terminal legs to a button of silk spun for the purpose by
the larva, and the attachment and suspension of the chrysalis by its anal spine to the silk
button. Reaumur represented it as accomplished by the chrysalis in its extensions and
contractions grasping the larval skin between the segments, and by this means raising
itself until it regained the button. Recently Mr. Osborne, an English Entomologist,
discovered a membrane serving as a suspensory agent in the change to the pupal state,
and for the first, questioned the account given by Reaumur. His observations were con-
firmed by those of Mr. W. H. Edwards, and followed up by additional observations on
large numbers of Nymphalidw and Danaide, some of which have been presented in the
- Canapian Enromouocist. There seems to be no question of the existence of such a mem-
brane, and that it consists of the portion of the larval skin lining the region of the rec-
tum, caught upon two knobs conveniently placed for the purpose. Prof. Riley, ina
communication to l’syche (vol. i1., p. 249) finds other means of chrysalis suspension—the
principal one being the shed intestinal canal, and accessory ones, the tracheal vessels of
the last pair of spiracles ; these Prof. Riley regards as the principal agents in suspension.
In opposition to this, Mr. Edwards considers these ligaments as of but little, if any, ser-
vice, and finds the membrane to furnish all the requisite support. Additional observa-
tions are required to reconcile these different views.

The beds of fossil insects recently discovered in the Tertiaries of our western Terri-
tories are proving to be wonderfully rich in number of species and condition of preserva-
tion. From a single small basin exposed by a railway cut in the vicinity of Green River
Station, Union Pacific Railroad,in Wyoming, Mr. S. H. Seudder in Fossil Insects of the
Green River Shales (Ball. U. S. Geolog.-Geograp. Surv. Terr., iv., No. 4, pp. 747-776)
enumerates eighty species, representing all the orders of the Insecta except Lopiloptera.
An idea of the richness of these beds may be obtained from the statement, that a two
hours’ search was rewarded by the collection of fifty new species. We are glad to learn
that Mr. Ssudder is engaged upon a general work on our fossil insects, which will form

2

18

one of the volumes of the quarto reports of the Hayden Survey—the beautiful typography
and illustration of which causes us to regret the prospective speedy termination of the
series. As the Tertiary Shales of the Rocky Mountain region give every promise of
being richer in insect remains than any other country in the world, the material for this
volume will be more ample than any other student in fossil entomology has been able to
command.

For the evident omission of reference to much valuable work done during the period
reviewed, Laskindulgence. The time tiat I had allotted to the preparation of my sketch
was found, too late, to be quite insufficient for the extended bibliographical examinations
required for even an approach to completeness. I offer it only asa partial sketch, and
as such please accept it. '

On motion, the thanks of the Club were tendered to the President for his able and
interesting address, with the request that a copy be sent to the Canapian EintoMOLOGIsST
for publication.

The Club next proceeded to consider the amendment to the Constitution proposed at
‘le St. Louis meeting, and after much discussion, the amendment was adopted in the
following form:—

ist—No resolution affecting important scientific questions shall be adopted at any
meeting of the Club unless there shall be present at least seven members who shall have
been enrolled at least one year previous to said meeting.

2nd—When any motion has been carried by the Club, such motion shall not be
rescinded at any subsequent meeting unless there shall be present at least seven
persons who shall have been enrolled as members one year or more previous to said
meeting.

3rd—Five members shall constitute a quorum for the transaction of ordinary
- business.

The Secretary was instructed to draw up a list of members of the Club, to be em-
bodied in the record of its proceedings, including all those who had been present at pre-
vious meetings.

The second meeting was held at 4:30 p.m., the President in the chair.

Mr. Grote exhibited specimens of Pseudohasis eglanterina sent him by Mr. James
Behrens, of San Francisco, who had collected them on the top of Mount Shasta. These
differed from the ordinary specimens in being almost entirely black on the upper side.
Mr. Grote expressed the opinion that this variation was mainly due to the climatic in-
fluences to which they were subjected in this elevated situation.

Dr. J. G. Morris referred tothe fact that certain Water Beetles carry with them
when they dive a globule of air underneath their bodies, and asked for information as to
what purpose it served. Mr. E. P. Austin said that this bubble was retained underneath.
by the stiff hairs along the abdomen, and as it was known that the air gradually disap-
peared if the insect remained long under water, it was supposed that the air was gradu-
ally uihaled by the insect, which was thus enabled to lengthen its stay under the water.

Mr. B. P. Mann presented a list of the Entomologists of North America, and re-
quested the members to confer with him as to additions and corrections. Some beauti-
ful examples of coloured drawings of Noctue by Mr. Pohlman, of Buffalo, were laid upon
the table for the inspection of those present, and were much admired.

Mr. Scudder called the attention of the members to a lepidopterous insect which
was doing much damage to the pines on the Island of Nantucket. Previous to the war
of 1812 the island was well wooded, but during that struggle the occupants were reduced
to such straits for fuel that they had burned every tree. For many years the island had
remained in a barren state, but some time ago plantations of Pines were begun, and a
broad belt of young trees of Pinus rigida from 10 to 20 feet high, with scrub Oaks, now
cover a large part of the island. The success of this experiment is seriously threatened
by the presence of the insect referred to, which is a Tortrix belonging to the genus Re-
tinia, and closely allied to duplana, sylvostrana and frustrana of Europe. The larva affects
the tip of each terminal bud and bores its way through this into the twig to the depth of
two or three inches, killing the terminal leaves and thus preventing the trees from mak-

US,

ing any growth. The moth is double brooded, and has not been observed in that local-
ity beyond the precincts of the island. Mr. Scudder also presented a plate with enlarged
drawings of the insect and its work.

Mr, Comstock had met with the same insect on P. inops, and had found that the
tips of the branches of the Pines were usually covered with a web. He had also found
another species of Retinia infesting the twigs of P. rigida. This latter bores into the small
twigs of the tree, from which exude masses of resin. The larva lives within the branch .
upon the wood, and before pupating forces its way through the mass to the outside.

Mr. Bassett had observed some fifteen years ago, about Waterbury, Conn., that the
common White Pine (Pinus strobus) was greatly injured at the tips of the branches by
Pissodes Strobi, but for the last ten years this pest had almost disappeared. Mr. Riley
referred to another Tortrix affecting the Junipers on Long Island, Dapsilia rutilana, a
European species recently imported.

Prof. Fernald stated that he had received from Oregon and Washington Territory,
specimens of Retinia duplana and sylvostrana identical with the EKuropean forms, and
further referred to the fact that in America the species of Tortricide are more abundant
in the West than in the East.

Mr. Grote called the attention of the membersto the ravages of Nephopteryw Zimmer-
mani, which he believed had inflicted more injury on young pines than any other insect ;
it is found throughout the northern and north-western parts of New York State. Mr.
Grote laid particular stress on the fact that the Kuropean pines imported and sold by
nurserymen are much infested, and desired to call public attention to this matter. With
regard to the use of Paris Green as an insecticide, he thought that it was doubtful
whether the injury caused by it was not greater than would occur from the Potato Beetle
were it allowed to go unmolested ; and instanced the loss of a stallion valued at $2,500,
poisoned by Paris Green, and also referred to the frequent injuries to animals and man
reported in the newspapers. ‘This opinion was opposed by other members present, who
stated that but for the use of Paris Green or some such poison it would be impossible in
some sections of the country to grow potatoes at all. :

Prof. Fernald referred to a Tortrix found in Maine, TJortrix nigridia, which had very
much injured the pines there ; he had ccllected a large number of the larve and chrysa-
lids of this insect, and from them, besides the moths, had obtained many ichneumon
parasites and also several hair snakes. Prof. Fernald embraced this opportunity of
calling the attention of the members to the condition in which be had found the types
of tue Northern American Tortricide. Many of them were being destroyed by the ver-
digris formed by the corrosion of the pins on which they were mounted, and in some
instances this verdigris has accumulated to such an extent as to burst the bodies of the
insects. To avoid this difficulty he has used japanned pins, and found that when thus
coated they remained free from corrosion.

Mr. Grote remarked that Scoliopterya libatrix was very widely distributed in this
country as well as in Hurope, being found here from Hudson’s Bay to the Southern
States. He also referred to Mr. Grey’s discovery that Limenitis arthemis, disippus, wrsula
and proserpina are connected by intermediate individuals, and that this indicated that they
had not long been separated from a common stock, and expressed the opinion that
arthemis was probably nearest the original form.

Mr. Lintner held that it was premature to conclude that the different species of
Limenitis are identical until it could be proven positively by rearing the one supposed
species from the eggs of the other.

Mr. Scudder exhibited a piece of a woody root which was represented as coming
from the interglacial beds of clay near Toronto, Ontario. This root proves by micro-
scopic examination to belong to a species of Juniper and is bored by an insect, probably
a Scolytus, but one which differs materially in its habits from any known species now
existing. Mr. Scudder also referred to the abundance of insect remains which he had
found in the peat deposits on the Island of Nantucket ; from one mass of about a cubic
foot he had obtained 300 fragments of Coleoptera, among which were several which he
had been unable to refer to any species now known to exist; a number of these speci-
Mens were shown to the members.

20

Mr. Austin exhibited specimens of a wasp, Polistes metrica Say,.infested with

parasites.
On motion the meeting was adjourned until 8 p.m.

EVENING SESSION.

Prof. Comstock exhibited specimens of a small Pyralid which is carnivorous, feed-
ing in the larval state on the maple tree bark lice, under the cottony matter secreted by
the lice. He had bred forty of the moths fed in this way.

Mr. Scudder drew attention to a very singular fossil, of which he had obtained
about 100 specimens, somewhat resembling the larva of an ingect, but yet quite differ-
ent from anything hitherto known. His remarks were illustrated by a figure of the
object. It consists of only six segments.

Mr. Barnard exhibited specimens of Phymata erosa, which has proved quite
destructive to other insects ; they have been known to destroy quite a number of Pieris
rape. Mr. Barnard exhibited a number of specimens which had been caught on the

burrs of the Burdock.
Prof. Riley stated that Pieris rape was now quite common in Alabama; it had been

seen as far as Selma, but had not yet reached Mobile. Mr. Scudder remarked that it

had been found in Savannah, Ga., two years ago.

Prof. Comstock had received specimens of the Colorado Potato Beetle, this year,
from Manitoba, and thought that this was the farthest point north it has yet reached.

Mr. Saunders made some remarks in reference to the capture of insects by the
flowers of a species of Bidens, probably chrysanthemoides ; the insects which he had
observed thus captured were Dipterous, all of whom had been caught by the mouth ;
some were found dead, others still hving, but unable to withdraw their proboscis.

In reference to the flight of butterflies, Mr. Lintner spoke of the enormous flocks
of Vanessa cardui which had been seen in Italy, Spain and Germany during the
summer.

Mr. Grote referred to an undescribed insect for which he proposes the name of
Oiketicus Abbotti; he had obtained the cases of this insect on the cotton plant in the
South, but had not seen the imago until he had reared it. This species is figured by
Abbot in unpublished plates in the British Museum; it is referred to also in Harris’
Correspondence, edited by Scudder.

The election of officers then took place, with the following result :—

President.—8. H. Scudder.

Vice-President.—A. R. Grote.

Secretary.—B. P. Mann.

A{ter some discussion it was agreed that in future it was desirable that the Presi-
dent and Vice-President hold office for one year only.

The meeting then adjourned until the afternoon of the following day.

WEDNESDAY AFTERNOON SESSION.

Dr. Morris mentioned an interesting case of retarded development which had come
under his notice, where a specimen of Papiliv asterias remained in the chrysalis state

two years and a half before the imago appeared.
Mr. Lintner remarked that instances of retarded development were common among

the Bombycide, and especially mentioned cecropia ; it also occurs frequently among the —

the Sphingide, where a specimen will pass over one season until the next in the
chrysalis state ; this has been supposed 1o be a natural provision for the perpetuation
of the species.

Mr. Bassett inquired whether in such examples they were not uniformly females.
Mr. Lintner stated that in his experience both sexes were retarded.

Prof. Martin exhibited transparent specimens of gum copal in which were imbed-
ded Hymenopterous insects. He stated that copal is a fossil resin of the post-tertiary
period obtained chiefly from Mazambique; that he had found in this resin about fifty
species of insects, about one-third of which were Coleoptera, one-third Diptera and the

ee ee

¥.

other third of the remaining Orders; two of the latter were Lepidopterous, one a
Geometer, and the other he thought belonged to Zygaenide.

Mr. Bethune mentioned that he had found the larve of the Colorado Potato Beetle
eating the leaves of the common Milk-weed, Asclepias.

Mr. Barnard had also seen one of these larve feeding on Milk- need but in this
instance the larva was hghter in colour than usual. Mr. Lintner remarked that it was
unfortunate that the Potato Beetle would feed in the larval state on quite a number of
different plants, and in the absence of vegetable food would sometimes feed on one
another.

Mr. Saunders had observed this carnivorous propensity of the Potato Beetle larve
on several occasions, and had seen the same among the Cut-worms, and in one or two
instances among larve of the Lycaenidae. Mr. Scudder had also observed similar habits.
Prof. Comstock had noticed it especially in the Cotton-ball worm Heliothis armigera.

Mr. Lintner invited Prof. Comstock to give some details in reference to the present
plans and operations connected with his department at Washington. Prof. Comstock
stated that he was endeavouring to work up a biological collection of insects on such
a scale and in such a manner as shall be a credit to the Government. He has a large
number of breeding cages, and an assistant who devotes his whole time to the rearing
and mounting of insects. Special attention has been paid this year to insects feeding on
clover, and the collection now contains over fifty species known to be destructive to this
valuable crop. Prof. Comstock asked the aid of all Entomologists and assured them
that any insects sent him would be well taken care of.

Mr. Scudder urged that Entomologists should recognize the fact that it is of the
utmost importance that a collection as complete as possible should be formed in
Washington, and that it should assume a national character.

Mr. Barnard asked for some information as to the method of arrangement adopted
in the collection referred to. Prof. Comstock stated that he arranged the insects in their
usual order and place ; with the insect, its usual food plant, and where it feeds on seve-
ral or many plants, a memorandum is placed with such specimen containing a list of
the plants ; by this method much duplication is avoided.

Prof, Fernald was asked to give some explanations regarding his work on the Tor-
tricide. He began the study of this group two years ago, commencing with those species
found in Maine, but soon found that he could do nothing satisfactorily without taking
in all those found throughout the United States and Canada. He has also found it ne-
cessary to study the European forms, x»nd is now engaged in examining all these strue-
turally, with the view, if possible, of improving their classification, and earnestly desires
help from collectors in all parts of the country, especially in reference to the larve of
the different species. He thinks that the character of the head, thoracic shield and anal
plate will probably be of most value in separating the species.

Mr. Saunders reported that Papilio cresphontes had been found rather common both
in the larval and perfect state in several parts of Ontario this season. Dr. Morris said
that he had found Papilio ajax particularly local in its distribution, abounding in some
localities, but very scarce in others.

Mr. "Lintner stated that Pholisora catullus had not been found about Albany until
three years ago, when a single specimen was taken ; this year it is one of the commonest
species in and about the city ; its food plant is Monarda punctata.

Rev. C. J. §. Bethune referred to the great abundance of Papilio philenor one sea-
son, many years ago in the neighborhood of Hamilton, Ontario ; since then he was not
aware that it had ever been found common in any part of Ontario.

A question was asked by Mr. Grote as to whether any of the species of Cucullia
ever come to sugar. In reply, Dr. Bailey stated that he had captured three species of
Cucullia and ten species of Plusia at sugar. Recently, when sugaring in a certain lo-
cality, he was surprised to find a large numberof Noctuids on decomposing animal mat-
ter, especially some partially decomposed deer hides.

Mr. Grote reported having taken Awdela acronyctoides ; one male was captured this
month at light. He thought that this was the first time it had been taken in New York
State.

22

Mr. Saunders referred to the fact that in the location where he resided large numbers
of the larvee of Clisiocampa sylvatica had died from a fungoid disease, and asked whether
any of the members had tried solution of yeast as an insect destroyer, as lately suggested
by Dr. Hagen.

Prof. Comstock stated that he had fed several larve on leaves dipped in yeast, but
so far the yeast-fed larve had thrived remarkably well ; his experiments had only been
continued but a short time, hence he was not prepared to give any definite opinion on
this subject.

The meeting then adjourned.

On Friday afternoon the closing session of the Club was held.

Dr. Morris stated that an apiarian in his neighbourhood had been severely censured
by some fruit-growers because his bees had pierced their peaches, grapes, etc., and
destroyed the fruit; he asked whether the bees really were the original authors of the
mischief, or whether they only attacked such fruit as had been previously pierced by
birds, wasps and other insects. He knew that writers differed on this subject, and men-
tioned that Prof. Cook and Prof. Riley take opposite sides here.

Prof. Macloskie thought that the mandibles of bees were not strong enough to tear
the outer covering of peaches or grapes. Prof. Comstock was of a different opinion.
Prof. Riley remarked that in some articles which he had published in the New York
Tribune he had proved that bees are the depredators, and made some further interesting
statements on this subject.

Dr. LeConte spoke of the destruction of some of our valuable forest trees by various
insects, and requested the members during the next year to collect facts and to report
them at the next meeting, so that the nature of their depredations may become fully
known and further remedies may be suggested.

Mr. Minot offered some very interesting remarks on the larve of a number of species
of water insects, chiefly Dipterous, illustrated by many beavtiful drawings of the larve
highly magnified.

Mr. Lintner referred to the importance of the study of aquatic larve, regretting
that so little was known of their habits, and hoped that Mr. Minot would continue his
studies in this direction.

From aquatic larve the conversation turned in the direction of that tiny tormentor,
the mosquito, and marvellous accounts of its abundance in certain localities, and the
sufferings of man and beast from its bloodthirsty propensities, were related by Mr.
Scudder, Dr. Morris and others.

Mr. Riley made some remarks on the Cotton Worm, and stated that he had bred
nine distinct parasites which preyed on this insect.

The time for adjournment having arrived, the members, after referring to the great
pleasure they had derived from the interesting sessions of the Club, unanimously ex-
pressed the hope that all present might meet again next year in Boston.

The following articles have been selected on account of their general interest from
the pages of The Canadian Entomologist, where they have appeared during the past year
as original contributions.

OBNOXIOUS PESTS—SUGGESTIONS RELATIVE TO THEIR DESTRUCTION.

BY DR. H. HAGEN, CAMRRIDGE, MASS.

The question how to check the ravages of obnoxious insects is a very important one,
and I am very often asked for advice in special cases. While occupied with a close ex-

amination of the proposed remedies and looking through a large number of scientific |

_ tracts, some of them fell into my hands and induced me to study them again. The
present communication is the result of those studies.

Somewhat more than twenty years ago the lower forms of some fungi attracted the
attention of many students, and especially of Dr. Bail, of Prussia. The reports of his
observations are scattered in different periodicals, and the final result of my study of
those reports was the conviction that a remedy for insect pests, offering several promi-
nent advantages, could be found in the easy application of the yeast fungus. Further,
that this remedy could be used probably against the famous Colorado grasshopper, for
the destruction of which the Government has appointed a commission appropriated with
$75,000; also, that the remedy could be tried in an easy way against the obnoxious
hairy caterpillars, against the potato bugs, and last, but not least, in every greenhouse
against leaf lice and similar pests.

Dr. Bail asserts that he has proved by many skilful experiments that four species
of microscopical fungi are merely different developments of the same species. One of
them, the fungus of the common house-fly, is the vexation of every housekeeper. The
dead flies stick in the fall firmly to the windows, or anywhere else, and are covered by a
white mould not easy to be removed. The second is the common mould, known to
everybody and easily to be produced on vegetable matter in adamp place. The third is
the yeast fungus, a microscopical species, and the basis of the work done by yeast of
fermentation. The fourth is a small water plant, known only to professional botanists.
Dr. Bail contends that the spores of the fungus of the house-fly develop in water in this
last species, out of water in mould, and that the seeds of mould are transformed in the
mash tub into yeast fungus.

The experiments made by Dr. Bail cover a period of more than a dozen years,
since the numerous objections which were made against his results induced him to
repeat again and again his experiments in different ways. I am obliged to state that
even now prominent botanists do not accept Dr. Bail’s views, which he maintains to be
true and to be corroborated by new and sure experiments. This question, important as
it may be for botanists, is without any influence regarding my propositicn, as Dr. Bail
has proved that mould sowed on mash produces fermentation and the formation of a
yeast-fungus, which kills insects as well as the fungus of the house-fly. I was present
at the lectures of Dr. Bail before the association of naturalists, in 1861, which were
illustrated by the exhibition of mould grown on mash, on which the fungus of the
house-fly had been sown, and by a keg of beer brewed from such mash, and by a cake
baked with this yeast. Both productions were declared perfect by all who tasted them
—an experiment in which I did not feel obliged myself to join, as both are to be had
prepared without the fungus of the house-fly.

In a later communication Dr. Bail states that the use of mould has been the secret
in brewing formerly certain kinds of a strong and well-reputed beer.

For the so-called jopenbier in Danzig the mash was not used before the forests of
mould grown on its surface had sunk to the bottom—or, in other words, till the spores
of the mould were sown by themselves on the mash.

Dr. Bail has proved by numerous experiments that healthy insects brought in con-
tact with mash and fed with it are directly infested by the spores of the fungus with
fatal consequence. These facts, not belonging strictly to the main part of his experi-
ments, were observed first by chance and later on purpose. The most different insects,
flies, mosquitoes, caterpillars, showed all the same results. The experiments were made
in such a delicate manner that a small drop of blood taken with an oculist’s needle from
the abdomen of a house-fly left the animal so far intact that the same operation could
be repeated in two days again. Both drops examined with the microscope proved to be
filled with spores of fungus.

More to the point are epizootics produced by this fungus and observed on insects in
the open air.

A really pestilential epizootic of the common dung-fly was observed in 1867. Not
only those, but many other insects, died in the same locality and in the same manner;
also other species of flies and gnats, the caterpillars of moths and of Phalenids, and
the common hairy caterpillars of a moth which is very nearly related to the famous
hairy caterpillar of the Boston Common. Of some species the destruction was so com-
plete that the next year they were very rare. During those years the caterpillars of

24

two species of moths had destroyed pine forests belonging to the State and valued at
several millions, and a larger calamity was imminent, when suddenly all caterpillars
died from the same fungus.

Similar observations have been made in other places in Europe and here. Mr,
Trouvelot formerly began in Medford, Mass., the raising of the Polyphemus moth for
silk, and was successful enough to get a prize in the Paris Exhibition of 1867. Unfor-
tunately he brought home from Paris eggs of another species from China, and purported
to be superior for silk-raising in the open air. Those eggs proved to be infested by
fungus, and the caterpillars hatched from them died, but not those alone. All caterpil-
lars of the Polyphemus moth became infested, and even most of the other indigenous
species living on the twelve acres of shrub land which Mr. Trouvelot utilized for this
purpose, died rapidly. After two years of a similar calamity, Mr. Trouvelot was
obliged to stop his experiments, which might have developed, perhaps, a new source of
wealth for this country. A similar pest of an indigenous species of moth stopped only
last year the interesting observations of Mr. Siewers in Newport, Kentucky.

The common silkworm in Europe has been in recent times extensively affected by
a sickness called muscardine, which is also the consequence of a fungus. Similar fatal
epizcotics have been observed on the honey bee, and in Brazil several years ago nearly
all the bees died from this cause. In Entomological journals are reported fatal
epizootics of leaf lice, of grasshoppers, of the cabbage butterfly and of the currant
worm, both imported here only a few years ago, and both very obnoxious.

Considering those facts, which are doubtless true, and considering the easy way in
which the poisonous fungus can always and everywhere be procured and adhibited, I
believe that I should be justified in proposing to make a trial of it against insect calami-
ties. Nature uses always to attain its purposes the most simple and Jee most effectual
ways ; therefore it is always the safest way to follow nature,

Beer mash or diluted yeast should be applied either with a syringe or with a
sprinkler ; and the fact that infested insects poison others with which they come in con-
tact will be a great help. Of course it will be impossible to destroy all insects, but a
certain limit to calamities could be attained, and I think that is all that could reasonably
be expected. In greenhouses the result would probably justify very well a trial, and on
currant worms and potato bugs the experiment would not be a difficult one, as the larve
of both insects live upon the leaves, which can easily be sprinkled. But it seems to me
more important to make the trial with the Colorado grasshopper. I should recommend
to infest the newly-hatched brood, which live always together in great numbers, and I
should recommend also to bring the poison, if possible, in contact with the eggs in the
egg-holes, to arrive at the same results, which were so fatal to Mr. Trouvelot’s silk-rais-
ing. After all, the remedy proposed is very cheap, is everywhere to be had or easily to
be prepared, has the great advantage of not being obnoxious to man or domestic animals,
and if successful would be really a benefit to mankind. Nevertheless, I should net be
astonished at all if the first trial with this remedy would not be very successful, even a
failure. The quantity to be applied and the manner of the application can only be known
by experiment, but I am sure that it will not be difficult to find out the right method. I
myself have more confidence in the proposed remedy, since it is neither an hypothesis
nor a guess-work, but simply the application of true and well-observed facts. I hear the
question—When all this has been known for so long a time, why was it not used long
ago? But is that not true for many, not to say for all, discoveries ? Most of them are
like the famous Columbus egg.

A SUCCESSFUL MOTH-TRAP.

BY O. S. WESTCOTT, RACINE, WIS.

Many attempts have been made to devise something by means cf which to capture
the Noctuids, but the results have been usually so meagre that the contrivances have
been abandoned in disgust. I have been using a contrivance this season which will

really abundantly repay one for the trifling trouble and expense involved in its construc-
tion. It consists first of a gallon glass jar, heavily charged with cyanide of
potassium. To the top of this is fitted a funnel. the spreading mouth of which opens
at right angles to the axis of the poisoned jar. The lower end of the funnel is four or
five inches below the mouth of the jar and has an opening three inches in diameter, the
funnel mouth being twelve or thirteen inches across. Opposite the mouth of the funnel,
and on the opposite side of the jar, is soldered to the funnel a sheet of tin so bent as to
thoroughly enclose a lamp. The lamp is supported by a piece of tin hinged to the outer
edge of this projection. The lamp being placed in position, the tin support is made to
rest upon the projecting part of the jar below its neck. Immediately in front of the light
is placed a sheet of mica. The whole contrivance is placed within a tight wooden box,
and a tin flap is also arranged. above the lamp chimney as a precaution against an un-
desired conflagration.

The moth attracted by the light, flies into the mouth of the funnel, is stopped by
the mica, and after fluttering a very short time, is so far overcome by the fumes of the
potassium as to fall within the poisoned jar, whence it cannot emerge. A projecting lip
of an inch or so in height is soldered to the lower edge of the mouth of the funnel in
such a way as to catch any insect that falls outside the mouth of the jar. It thus is
most likely to return to the light. I have taken with this contrivance hundreds of Noc-
tuide and Coleoptera, among the former many things—especially among the Tineidee—
entirely new to my cabinet.

A CHEAP ENTOMOLOGICAL CABINET.

BY W. H. HARRINGTON, OTTAWA, ONT.

I have recently been looking over the back volumes of the Entomologist, and have
found them, as I do the later numbers, very interesting and instructive reading. Among
other valuable items, I have noticed suggestions regarding the construction of cheap
cases for holding specimens, and as the question of expense is always an important one
especially to young collectors, I will, if you can spare me space, briefly describe the style
of cabinet J am now using, and which has been adopted by one of my friends.

Among the substitutes for cork mentioned by Packard (in his Guide to the Study of
Insects) are thin frames covered on each side with paper and fitted into the bottom of
drawersinacabinet. NowI have gonea step farther, and discarding the drawers entirely,
have adopted the frames and adapted them to a cabinet without drawers. This cabinet can
be made of any size and be divided by upright partitions to suit the taste of the owner,
and the frames can run in grooves made in the sides and partitions before it is put to-
gether, or between movable strips tacked or screwed in afterward at suitable distances,
say two inches. The one I now use (a small one made as an experiment) is three feet
two inches wide inside, with two partitions, so that there are three spaces each one foot
in width. It is fifteen inches deep and two feet high. Placing the frames two inches
apart gives me twelve in each section, or thirty-six in all, and as each has a surface of
twelve by fifteen inches, I have an aggregate expanse of thirty-six square feet. The ad-
vantages claimed for this cabinet are its lesser weight and expense. It is easily handled
and can stand pretty rough usage without fear of damaging specimens, as the pins are
firmly held, and the frames, running in grooves or between strips, cannot stir when the
door shuts close against them. It does away with the expense of drawers, the cork alone
for which (thirty-six feet at 18 cents per foot) would be $6.48. The frames constructed
of thin stuff (say quarter-inch) cost at the most five cents each, and suitable stiff cart-
ridge paper is very cheap. If the frames are made slightly smaller than those mention-
ed one sheet will cover both sides of two frames. The paper is put on when damp, but
should not be too wet. The frames can be easily re-papered if needful, and if the sec-
tions are made of equal width, they will all be interchangeable, which will be found a,
great convenience.

26

This manner of keeping specimens will, I think, be particularly useful to collectors
of Coleoptera. I send this, feeling that each member of the Society should contribute
his mite of experience and knowledge for the benefit of his fellow-workers.

NOTES ON A WINTER HOLIDAY.
B. W. SAUNDERS, LONDON, ONT.

During a recent holiday, while on a trip South, I spent a day among the Entomolo-
gists at Albany, N.Y. To say that it was a pleasant day, an exceedingly enjoyable day,
would convey but a faint idea of the pleasures there experienced. Arriving early in
the morning, I made my way to the State Museum of Natural History, where under
the guidance of Messrs. Lintner, Meske and Hill, three veteran Entomologists, I had
the pleasure of inspecting the countless rarities contained in the collections of Lepidop-
tera made by those gentlemen in this vicinity. I have seen many collections in the
course of my wanderings, but for multiplicity of species, full series of rarities and
matchless perfection of individual specimens, it had never before been my pleasure to
witness anything that would compare with the valued stores contained in the cabinets
of these enthusiastic collectors at Albany ; and without fear of contradiction, it may be
said that the Entomologists resident there have contributed more towards our know-
ledge of the Lepidoptera native to the northern portions of America, than any other
equal number of collectors in the country. The enthusiasm they have long maintained
and their indomitable perseverance have enabled them to overcome almost every obsta-
cle and accumulate such wonderful series of specimens, especially by night captures at
eugar, as no less favoured Entomologist could look over without feelings almost akin to
envy. After one had seen scores upon scores of individuals of some rare Noctuid,
which in one’s own collection had perhaps long been represented by a treasured frag-
ment, the question would frequently rise as to whether anything in this line be rare in
the neighbourhood of Albany.

During the day I was also privileged to see the magnificent series of Catocalas in
the collection of Dr. Jas. H. Bailey, and one could only regret that the day was too
short to do any sort of justice to the mass of material to be inspected. After labouring
busily from early morn until late at night, we parted at the railway station, with the
most pleasant recollections of a day happily spent amidst old and and newly-found
Entomological friends.

On reaching Washington, Nov’r 28, a brief visit was paid to the Entomological
rooms, in the Department of Agriculture, where I had expected to find my esteemed
friend, Prof. C. V. Riley, but unfortunately business had called him away from home.
Through the kindness of Messrs. Pergande and Howard I was shown very many things
of interest, especially in the way of insects in their earlier stages, both living in breeding
cages and preserved as blown larvae, and in this way a very pleasant and instructive
hour or two was spent. It was a source of grief to learn from our good friend, Chas, R.
Dodge, that “ Field and Forest” was about to be discontinued for want of sufficient sup-
port. This valued periodical has done good service in the cause ot Natural Science,
awakening an interest in this direction in many minds, and in its decease we have lost
a valuable aid. It gave me much pleasure to find that veteran Hutomologist, Prof. T.
Glover, with health almost restored, busily engaged in his Entomological work. Through
the affable kindness of Dr. T. V. Hayden, I was shown through the Department of the
Interior, that great national laboratory from whence has issued so many works invalu-
able to the naturalist in every field of labour. After lingering long among the many inter-
esting objects which claimed attention, I returned laden with useful works and pamph-
lets on subjects relating to Entomology, deeply impressed with the important work here
carried on by a great and progressive nation in the interests of science; and with very
pleasant recollections of the great personal kindness shown me by the worthy and dis-

, tinguished head of this most useful branch of the national service.

27

The Smithsonian Institution was also visited, with its immense collections and
innumerable objects of interest, and through the kindness and liberality of the Secretary,
some recent and valuable works on Entomology and kindred subjects were secured for
our Society’s library.

Passing through Virginia, the Carolinas and Georgia, we landed in Fernandina,
Florida, with its historic surroundings, on the 30th day of November, where everything
assumed a tropical aspect, the landscape dotted with palms, orange trees, magnolias,
live-oaks, and other evergreen trees, and the air so balmy as to at once suggest thoughts
of butterfly nets and collecting bottles. Of the latter a supply was at hand, bnt not ex-
pecting to meet with anything on the wing, insect nets were left folded away in their
wintry home. Many logs and chips were turned over in search of insect life, but very
little was found. Subsequently, while wandering about in Jacksonville, I saw several
butterflies on the wing, most of them unfamiliar ; that charming yellow Callidryas eubule,
was recognized as it floated about among the beautiful roses, jessamines, poinsettas and
other flowers in the gardens, and one longed for a net that he might cultivate a closer
acquaintance with this and some of the other interesting species. An old friend,
Danais archippus, was frequently met with, and reminded me of summer at home.
Florida, however, is very poor in insects at this season of the year, but as summer ap-
proaches it is in many parts a paradise for the collector. During a week spent in this
land of flowers I travelled over 800 miles along its rivers and railways, seeing much of
its characteristic scenery, the most southerly point touched being Leesburgh, on Lake
Griffin, a little south of the 29th degree of latitude and 800 miles south of Jacksonville,
by tortuous river travel. Here butterflies were more abundant, and having landed with
a very pleasant party in an orange grove, amidst half a million of oranges on 2,500
large bearing trees, one was puzzled what to do first. The oranges were tempting, but
the sight of beautiful specimens of Agraulis vanille, D. berenice, with charming Heliconias,
Theclas, etc., was still more overpowering, and with hat in hand, the butterflies were
vigorously pursued until several specimens had been secured, but with such imperfect
means of capture at hand, the beautiful insects were battered and torn, and ones cloth-
ing having become covered with malignant burs collected in the chase, it was thought
best under the circumstances—the first burst of enthusiasm being over—to devote more
particular attention to the orange question.

While vigorously consuming oranges, enquiries were made as to whether the trees
or fruit were subject to insect enemies. Beyond occasional specimens of the larva of
Papilio Cresphontes, I could not learn of any caterpillar which consumed the leaves, and
the only insect which seemed to trouble the orange growers at all was a species of Coccus
—Aspidiotus citricola—which attacks the bark and foliage of both the orange and lemon
trees, and occasionally, if very numerous, gives the tree a sickly appearance. But such
an effect was rare, and one could not help feeling astonished at the luxuriant and vigor-
ous growth of the average orange grove and the symmetry and beauty of the trees laden
with their golden fruit, in soil, in most instances, so poor that one wondered where the
nourishment came from. In our course up and down the Ocklawaha River, where the
trees are everywhere clothed with the beautiful Florida moss, Tillandsia usneoides, and
the swampy margins decked with brilliant asters and other composite flowers, many
Neuropterous insects were seen on the wing, but none were captured ; indeed, the catch-
ing of an insect seemed insignificant work in the midst of the excitement attendant on
the shooting of alligators, herons, ducks and other large game, and at the close of the
week there were very few spoils wherewith to grace the Entomological cabinet. Now, a
few days later, amidst frosts and snow, the novel recollection of the recent heated butter-
fly chase, the cooling off under the shade of orange trees, imbibing the sweet rich juice
of the fully-ripened fruit, and the additional novelty of a sunburnt brow, all in the midst
of the month of December, are things not soon to be forgotten. 5

THE CLOVER-SEED FLY—A NEW INSECT PEST.
BY J. A. LINTNER, N. Y. STATE MUSEUM NAT.. HIST., ALBANY.

In the summer of 1877, my attention was called to some ‘‘ worms” which had been
discovered in the heads of red clover ( Trifolium pratense), and were said to be preying
upon the seeds. They were found to be minute maggot-like creatures, hidden within
the seed-pods and entirely destroying the seeds which they attacked. Numbers of
them were subsequently detected in the examination of heads of clover taken from
several localities in the vicinity of Albany, and in Warren County, N.Y. I was unable
at the time to refer the insect to any described species, or to find any record of a similar
depredation on clover seeds in this country or in Europe.

The following season additional examples of infested clover heads were submitted
to me, which had been sent from Mr. George W. Hoffman, Presiden tof the New York
State Agricultural Society, from Elmira, N. Y. A number of the larve were obtained
from these heads, and their careful examination enabled me to refer them to the Ceci-
domyidz—of a species probably closely related to the well-known wheat-midge, Ceci-
domyia destructor. Several of the larvee were preserved in alcohol, and the larger
number placed in a pot of damp sand, in which they speedily buried themselves for
their transformation.

At the annual meeting of the N. Y. State Agricultural Society, in this city, in January
last, in a paper presented to the Society on some injurious insects observed during the
past year, I gave an account of this new depredator upon an important crop, and
described its larva as follows:

Cecidomyra leguminicola, n. sp.—Head subacute, subtriangular, slightly rounded
laterally on its posterior haif, giving that portion a subquadrangular form; a short
cylindrical horny ? process at its tip, and two longer antennal processes, cylindrical,
tapering apically. Body eriptical, moderately constricted at the joints, flattened on
the sides, rather rounded behind, delicately shagreened, laterally at about the middle of
each segment, a short fleshy papilliform process, with two short bristies of unequal
length near the posterior of the segment; posterior segment bilobed, each lobe armed
with two short fleshy ? processes, of which the outer is the longer; ‘‘ breast-bone”’ of a
pale yellowish colour, its projecting end divided into two rather blunt, laterally rounded,
points. A dorsal row of processes similar to the lateral ones is suspected, but was not
definitely made out. Colour of the living larve, pinkish, approaching orange; length,
0.08 of an inch.

The reading of the paper elicited the information that the insect had committed
serious depredation upon clover-seed in Tompkins, Seneca and other counties in Western
New York, during the past year. In Seneca County, fields of clover which had been
kept for seed, proved to be not worth the cutting. It was also stated that a worm
similar to those in the heads had been discovered preying upon the roots, but these are
probably the same larve, which having matured, had left the heads for their pupation in
the ground, where the Cecidomyide larve frequently remain unaltered for a considerable
length of time.

The extent of the ravages throughout our country of this newly discovered insect,
which promises to be of considerable economic importance, will be an interesting subject
of inquiry for the ensuing summer; and the interesting question also arises, now that
its hidden covert has been detected, will the species also be discovered in Europe, whence
the red clover was introduced in this country.

I have been successful in obtaining examples of the imago of Cecid. leguminicola.
Anticipating failure (since realized) in my efforts to rear it from the larve obtained by
me last year, I applied, in May last, to Mr. R. J. Swan, of Geneva, N. Y., who at the
annual meeting of the N. Y. State Agricultural Society, in January, had spoken of the
occurrence in very large numbers of the larve in a clover field upon his farm, request-
ing that some of the surface soil from the field might be collected and forwarded to me.
A small box of the earth (containing also some of the clover roots) of about six inches

a

Soe

29

cube, was received by me on the 2nd of June, and spread out in a glass-covered case.
On the following morning a male and female were found in the box. Additional
examples were disclosed from the earth—about twenty-five in all—from that time to
the 27th of June, since when none have been obtained. They had undoubtedly com-
menced to emerge during the month of May.

Marked features of the species, which will serve in its recognition, are the genitalia
of the male, which are quite broad, projected on a pedicel, and arranged in an extended
pair of clasping organs; and the long jointed ovipositor of the female, of about twice
the length of the abdomen.

The antenne of the Cecidomyie afford perhaps the best features for determination
of species. The following description of the antenne of the male of C. leguminicola
was drawn from fresh specimens just after death:

Number of joints seventeen in ali—the basal one coloured and short, the next one
black, short and naked, followed by fifteen verticillate ones. Joints on penduncles as
long as the joints, subcylindrical with rounded ends, about one-half longer than broad,
rather thickly verticillate ; the longest hairs nearly three times as long as the joints,
and projected at nearly right angles to them; the shorter hairs about equal in Jength
to the joints, some of which curve upward and have their tips nearly in the plane of
the succeeding joint; joints regularly and gradua!ly diminishing in size to the terminal
one, which is about but one-half the size of the penultimate one, and of an ovate form.

The wings are clothed with numerous short, curved, blackish hairs, which give
them a dusky appearance ; ciliz paler, long. The abdomen is fuscous, marked on each
segment dorsally with black hairs forming a segment of a circle having the curve in
front. The thorax is black above, clothed with rather long hairs.

The insect is in all probability quite generally distributed throughout the State of
New York, and will be found in adjoining States. On the 1st of July, examples of the
larve were obtained from clover heads gathered by me on Mount Equinox, Vermont, at
an elevation of 2,500 feet above tide. On July 5th, although a late period for the larve,
mature specimens were taken from clover growing within the city of Albany, from the
sidewalk of Western Avenue. The only example of the fly which has up to the present,
so far as my knowledge extends, been taken at large, was captured on the Hudson
River, in the vicinity of Castleton, on the 16th of the present month (July), by Mr.
Dempster A. Lansingh, of Albany. The keen eye that could detect so minute an
object on the crowded deck of an excursion buat, deserves to be trained for use in
entomological science.

From information kindly communicated to me by Prof. Wm. H. Brewer, of Yale
College, New Haven, Conn., it is very probable that the existence of this clover pest
was kuown at Jeast thirty years ago. He writes as follows:

‘““My father, Henry Brewer, of Enfield Center, Tompkins Co., N. Y., was an
enthusiastic grower of clover and clover-seed as far back as I can remember. Many
years ago—how long, I cannot definitely say, but certainly before 1848, it was known
to us that an insect attacked the clover, which hatched out a fly. Our belief then was
that the larva existed within the seed. On two occasions I hatched out the flies and sent
them by mail to Albany, to the Entomolozist there—once before 1848, and once later,
somewhere between 1851 and 1855. The fly was very small and very slender, but
having been found so many years ago, that is all the recollection I have of it. The
clover heads were not affected externally by its presence.”

There cannot be much doubt but that the above insect is identical with the little
midge which has so recently commanded our attention, as the result of its multip'ication,
or, as is more probable, from a period of its unusual abundance. Accepting their
identity, it is quite interesting that the first notice of tne species, so far as known, comes
from a county which is believed to be suffering more from its depredations, at the pre-
sent time than any other portion of the State.

From the July number of the American Agriculturist, I learn, for the first time, that
Prof. Riley has been engaged in investigations on this interesting insect. Tue article is
drawn from a conversation with Prof. R., and in part from a communication by him a
short time ago to the VW. Y. Tribune. It contains a notice of the depredations, trans-

30

formations and appearances of the midge, and is accompanied by excellent figures of the
male and female with enlargements of parts, which will be of great service in its identi-
fication.

Perhaps a few additions to Mr. J. A. Lintner’s very interesting article will not be
out of place. In 1872 the late Mrs. W. P. L. Garrison came to visit the Museum, and
told me about an insect destroying the carpets in Buffalo, N. Y., and named there ‘‘ the
Buffalo pest.” I had not then heard anything about the insect, and Mrs. Garrison, after
her departure, was kind enough to send me some living specimens from Buffalo. I bred
them here in the Museum, and determined them as 4Anthrenus scrophularie L. The fol-
lowing years I had numerous inquiries from Cambridge and Boston in relation to this
carpet pest, and I traced about three-fourths of all cases to a large carpet store in Wash-
ington St. in Boston, where the carpets were bought, and what ought not to have been
done, they were directly laid in the rooms, without beating them before strongly and
disinfecting them in some way.

Mr. Lintner was unable to find any record of its preying upon carpets or other
woollens in the Old World. But there exists enough in the literature. Dr. H. Noerd-
linger, in his well-known book, “ Die kleinen Feinde der Landwirthschaft,” etc., 1855,
8vo., p. 90, states as follows :—

‘The common flower-beetle, Anthrenus scrophularie, is from April common on
many flowers, especially on fruit trees and roses. It is common also in houses, etc.,
where it can become very obnoxious by the destruction of furs, clothes, animal collec-
tions, and even leather and dried plants. The obnoxious larva, which naturalists should
take care to avoid, is common in closets and rooms in the attic, where it finds dead flies
and from whence it likes to enter the other rooms.”

T have taken Noerdlinger’s book at random, but it would not be difficult to find
such notices in similar books. To show that this pest is not a new one, I add two older
authors taken at random.

F. W. Herbst, Coleoptera, vol. 7, 1797, p. 828, says:—‘‘ This beetle is everywhere
very common in rooms, on buds, and especially common on tulips. It destroys, as well
as its relatives, collections of insects and plants. The larva lives in he houses, like the
Dermestes, and destroys all kinds of collections of natural objects, cloths, furs, leather and
victuals.” The variety of A. scrophularie—sutura grisea—is described from Europe by
Illiger, 1798, p. 398. F. Wiegmann, Handbook der Zoologie, 1832, p. 308 :—“ The
larva lives on animal matters, and is sometimes very injurious to hides.”’

I have ascertained this summer that the carpet bug eats of a piece of cloth consist-
ing half of worsted, half of cotton, only the worsted threads, and left the cotton threads

uninjured.
I may add some words concerning the list of the obnoxious insects introduced from

Ee a ae ony

¥

dl

Europe into America. Itis, as I believe, overlooked that about three-fourths of the
insects enumerated are surely not originally Kuropean insects. They were introduced
into Europe from the Kast by the advancement and progress of culture, and in the same
way by the advancement of culture from Kurope to America. The same is the case with
the common weeds, and some years ago, by carefully comparing the list of HKuropean
weeds in Prof. Ratzeburg’s work with the lists of the described American plants, I found
out that two-thirds of all European weeds are common in the United States, and perhaps
a part of the last third, of which I was not able to make certain. I myself was at first
much surprised to find in the middle of the prairie, near the railway to St. Paul, Minn.,
common Kuropean weeds. I should state that I share entirely in the wishes of the inhabi-
tants of N. America to receive and enjoy progress and advancement of culture, with-
out the accompanying drawbacks which nature seems to have so closely united with
them.

After all, I should state that it is remarkable that such pests as the Colorado beetles
- emigrate very exceptionally from the west to the east; so the locust tree is even now
entirely free from pests in Europe, though imported a century ago and very common
everywhere. ‘There are some American insects imported into Kurope which have been
overlooked. Slatta Americana is common in all sugar refineries to Archangel, and
everywhere in large cities in store-houses. Termes flavipes 1s probably also imported
from this continent. Blatta orientalis was imported from Asia to the west of Europe, and
made from there a well ascertained migration to the east again and through Siberia.
All insects finding it easier to live in the company of man, or by articles used and needed
by man, will of course follow him as well as dogs and rats.

Mr. Lintner has not mentioned Phylloxera, which has in Kurope done more injury
and has caused more losses than almost all the other pests together.

NOTES ON THE HUMBLE BEES.
BY G. J. BOWLES, MONTREAL, P. Q.

(Read before the Montreal Branch of the Ent. Soc. of Ontario.)

Packard places the Hymenoptera at the head of the Class Insecta, on account of
the completeness of their transformations and the perfection of their instincts. This is
also the position assigned to this Order by Dana. Packard ranks the Bees (Apide) at
the head of the Hymenoptera, thus placing them at the very summit of the insect crea-
tion. Cresson, however in his ‘‘Catalogue of the Described Species of N. A. Hymenop-
tera,’’ has them a long way down the list, after the Ants, Wasps, etc. Who shall decide
when such authorities disagree ?

I wish to draw attention to the Humble Bees of this part of Canada, giving, as far
as I can, the names of the species found here and some notes on their economy, the lat-
ter chiefly taken from Putnam’s paper published in 1863.

The genus Bumbus, says Swainson, appears to bea Northern and chiefly Kuropean
and American genus ; there are very few inter-tropical species, and very few Oriental.
Some of the tropical species, however, are very large, much larger than those found in
temperate climates. As regards North America, Cresson, in 1863, enumerated 46 spe-
cies, of which the greater number are found in the northern part of the continent. I
have carefully tabulated his list, and find that the arrangement of their habitats is as
follows, beginning at the south: Mexico 6, Southern States 8, Middle 7, Western 5,
Kansas and Utah 8, California 2, New England 8, Canada 7, Hudson Bay 5, Arctic 13,
Sitka 3, Greenland 1, unknown 8, and one species from Antigua. The large number
from Arctic America is surprising, and would lead oneto think that the number given for
the more southern parts is not correct. The Arctic species, however, are peculiar to that

32

part of the continent, only three of them being found in Hudson Bay Territory, and only
one of them coming as far south as Canada. Many of the other species are also local,
but some are found over a wide area. Thus virginicus is found all over Canada and the
United States, east of the Rocky Mountains, vagans from Canada to the west, fervidus
pennsylvanicus and separatus the same, and ternarius, the only arctic species found in
Canada (according to Cresson), seems to extend also over the North-Hastern, Middle and
far Western States. Britain possess about 40 species.

The common name, Humble Bee, is said to be derived from Hummel or Hummer
Bee, alluding to the noise made by the wings during flight. In Scotland the largest
species found there is called the Bumbee.

In North America the Humble Bee is the nearest approach we have, as far as
indigenous Bees are concerned, to the Hive Bee. The latter (4. mellifica), however,
has become naturalized on this continent in the forests to a considerable degree beyond
civilization, making its nests in hollow trees, or among the branches, sometimes under
ledges or in clefts of the rocks. It is said not to have been found to the West of the
Mississippi before 1797, but in fourteen years it had advanced 600 miles further in that
direction. I have never heard of the Honey Bee becoming wild in Canada, but it
probably would if neglected when swarming takes place.

To return, however, to the Humble Bees. ‘They do not form communities so large
as Honey Bees, seldom more than two or three hundred cccupying one nest, in some
species not more than fifty or sixty. The community is dissolved on the approach of
winter; the males and workers die, and only females have the power of passing the
winter in a torpid state, among moss, in rotten wood, or in some other situation where
they may enjoy protection from frost and concealment from enemies—to perpetuate the
race by founding new communities in the ensuing spring. Workers are chiefly produced
in the earlier part of the season, males and perfect females in the latter part of it. The
females are much less prolific than those of Honey Bees, aud seemingly as a kind of
provision for this deprivation, they, unlike the Honey Bees, live in the same community
without seeking to destroy one another, provided they belong to the same colony or nest.

Their nests are placed in different situations, some species having different habits
from others in this respect. Thus of the English species, B. terrestris makes its nest in
holes in the ground, at the depth of a foot or more, floored with leaves and lined with
wax, and often entered by a winding passage. Others, as JB. lapidarius, make their
waxen nests among stones; others, as B. muscorum, among moss, which they mix and
join with wax. The nests are enJarged as the community increases. In the spring the
female or queen bee, having awaked from her torpid state, roams about until she finds
a suitable place for a nest. On deciding, she immediately collects a small amount of
pollen mixed with honey, and in this deposits from seven to fourteen eggs, gradually
adding to the pollen mass until the first brood is hatched.

As regards the Bees which I have examined, some were taken at Quebec by me
some years ago, and one or two species here. I have to thank Mr. Caulfield for the
principal part of the material.

There are certain differences between the sexes which render it easy to distinguish
them. Not to enter too scientifically upon this part of the subject, I give the principal
points of difference.

The females may be known by their large size, and the corbicule or baskets on the.

posterior tibie, formed by a fringe of long hairs on each side.

The workers generally resemble the females very closely, the ouly observable differ-
ence being in the size, and this varies greatly. They may be found of all sizes from the
female downwards, so that it is impossible to tell the difference in some cases.

The male is smaller than the female and larger than the generality of the workers.
It has one joint more in the antennz and one section more in the abdomen than the
female.

Cresson says a very conspicnous character to distinguish the sexes is this: In the
male the inner tooth of the tarsal claws is almost as long as the outer, in the female
the inner tooth is quite short compared with the outer. The posterior tibiew are without
baskets, but have a fringe of hairs on the outer side.

Apatuus, Newn.

The following remarks on this genus are from Mr. Cresson’s “ List of the North
American species of Bombus and Apathus,” Proc. Ent. Soc’y Phil., 1863:

This genus is parasitic on that of Bombus, and resembles it very much in general
appearance. The characters with which to distinguish it from Bombus are as follows :—
The posterior tibie are destitute of corbicule (or baskets) and are convex exteriorly ; the
basal joint of the posterior tarsi has no tooth at its base above. In the female the apex
of the abdomen curves under, and the apical segment beneath has the lateral margins
elevated. The mandibles have a single notch, while those of Bombus are distinctly
toothed. This genus has uo workers.

The males may be distinguished from those of Bombus by the posterior tibia being
exteriorly convex and thickly coated with short hairs. The males of the latter genus
have the exterior surface of the posterior tibiw concave in the centre, with a few scattered
hairs, and are fringed at the exterior margins.

The economy of our species is almost unknown.

INSECT DESTRUCTIVE TO PINE TREES.—NEPHOPTERYX ZIMMERMANI.
BY D. S. KELLICOTT, BUFFALO, N.Y.

This pine-boring Pyralid was described by Prof. A. R. Grote in a paper read at the
Nashville Meeting, 1877, of the American Assoc. for the Adv. of Science, and published
in Canadian Entomologist, vol. ix., 161. During the summer and autumn of 1878, and
again this year, I have made some observations upcen the occurrence, larval habits and
parasitic enemies of this moth, and am able to state concerning them some additional
facts of interest.

The moth, it appears, is pretty widely spread, and it seems rather odd that it should
not have been discovered until 1877, having been overlooked by our excellent economic
Entomologists. I have met with it in some one of its stages in the following localities:
It occurs not uncommonly in both foreign and native pines in and about Buffalo ; many
of the trees of this species in the Niagara St. Parks have been bored by it. I found it
quite abundant in small white pines of the forest at Chehtowaga, Hrie Co., N. Y. At

3

34

this place I found many plants had been dwarfed and ruined by their ravages. It also
occurs, to what extent I am unable to say, at Hamburg and Clarence Center, in the
same County. LIrecently visited a portion of this State, Oswego Co., formerly clad to some
considerable extent with white pine, and there are yet standing some virgin forests of
this splendid tree. In divers places in that county I found our borer ; it is so abundant
in one locality, at least, that it proves a grave enemy to the young pines of second
growth where the primitive trees have been removed by the lumberman. ‘There is near
Hastings Center an ‘old slash” in which at least one-half of the many such small pines
have been injured ; indeed, in one neglected corner, among séores, scarcely one tree had
escaped. In this instance, also, many pines were stunted, while some thus weakened
had been broken off by the wind. In other localities where the pine is indigenous I
have been unable to find it, or else it was only occasional; for example, at Portage,
where young pines are plentiful, and although the trunks bore masses of pitch closely
like those from the wounds by Zimmermani, yet a diligent search discovered but one
pupa skin, and of the identity of it I am not quite certain, as it was badly broken in re-
moving from the pitch.

April 12th last, at Hastings, I took many larve of various sizes from .25 to .7 of
an inch in length when crawling, so there is no longer a doubt as to the winter stage.
None of these taken were “livid or blackish green,” but dull white ; nor do the hairs arise
from a “series of black dots,” but from light brown ones. I take it to be a case where a
naked hybernating larva is lighter than during the warm summer. Otherwise the cater-
pillars were as described by Mr. Grote.

In a clump of pines whose trunks were from 6 in. to1 ft. in diameter many of the
larger ones had been “boxed,” i. e., inclined incisions had been cut by the axe through
the sap-wood in order to catch the pitch exuding from the wound. Around the borders
of these ‘‘ boxes” the galleries with both pupa skins and living larve were plentiful. It
appears that the larva cannot penetrate the outer bark of other than quite tender trees ;
nor could I find evidence of their attacking the branches of larger trees, although I had
opportunity to examine such that had been felled during the winter just past. Since
this larva so readily take advantage of a wound, may it not stand related as a messmate
to other borers ? At both Chehtowaga and Hastings I found on trunks in the same neigh-
borhood masses of exuding pitch in which were larve of an orange colour, attaining a
length of .45 of an inch, remaining through the winter, and going into pupa towards
spring, as I found them in both conditions April 12th and early in May. These larve
are those of one of the pine weevils. It appears to me that Zimmermant may and
does take advantage of these wounds by the weevil, as it does of those made by the axe.

I have found the moth’s galleries in both trunk and branch, both above and below
the whorls (usually below), sometimes completely girdling the stem, thus killing the
portion above; in one instance I found a gallery passing from one whorl to the one
above.

Now, when the moth borer and the weevil work together and pretty much in the
same way, 7. e., by cutting the inner bark and the cambium layer, thus scoring and
girdling the stem, to which culprit belongs the greatest amount of credit for mischief ?
Both are guilty of enough to justify everlasting execration.

It remains to add a word about its insect enemies. The hymenopterous parasite
which Mr. Grote found to fill certain of the chrysalids, I have found in every location
where the moth is at all abundant ; there is another which I have found quite as abun-
dant. Early in April I obtained from the galleries of last year a number of brown
cocoons, about .4 of an inch long, nearly cylindrical, ends rounded, texture thin papery,
pupa visible through the cocoon. The skin and head of the victim was found at one end
of this cocoon, showing that the caterpillar was the host.

In a few days there appeared from each cocoon a lively fly. Expanse of male, .6
in.; of female, .7 in. Colour above black, legs yellow, underside of abdomen white with
arow of black dashes on side, front of male white, of female black. A white line on
shoulder cf each extends on to the costa. Ovipositor as leng as the abdomen.

I shall presently refer the species for identification.

NOTES ON THE LARVA OF THE MAY BEETLE—LACHNOSTERNA FUSCA.
BY L. 0. HOWARD, WASHINGTON.

The following note may prove of interest as showing the numbers in which the
larve of Lachnosterna fusca may exist in a lawn without perceptible damage to the grass
resulting.

On the 17th of September, while walking through the Capitol grounds a few hours
after a heavy shower of rain, I observed these larve in great numbers upon the stone
pavement north and east of the Capitol building. I counted up to three hundred, and then
came to a spot where they were so thick that Lhad to give it up. I certainly saw thousands,
nearly all of which were dead, either from heat or from having been trodden upon. Upon
interviewing the Superintendent of the ground, I learned that at this season of the year the
grubs always make their appearance in like numbers afterahard rain. This gentleman
informed me, and his statement was corroborated by several others, that frequently
the sweepers of a morning in going over the walks would collect at the bottom of the
hill as many as a bushel of the grubs. The pavement is edged on both sides by a two-
inch curb, and the larve falling over this are unable to return ; only those grubsinhabit-
ing the earth near the curb would reach the walk, and the great numbers killed in this
way after every shower afford an index to the immense number which the entire lawn
must contain. Yet, in spite of this most serious drawback, as one would naturally
call it, the grass over the entire plot is so fresh and green as to call for universal
admiration.

The movements of the larvee upon the smooth pavement were very interesting. The
characteristic bend of the body unfits them for walking on smooth surfaces, and every live
individual that I observed was upon its back, moving forward quite rapidly by the alter-
nate expansion and contraction of the segments. This mode of locomotion seemed strange
at first, but upon reflecting that the probable natural position of the larva in the earth is
upon its back with its legs grasping the grass roots, it seemed not so unnatural after all.
The strong transverse corrugations and rows of bristles upon the dorsum, taken in connec-
tion with the extremely business-like and natural air with which the larve took this
position and the rapid progress which they made while in it, would seem to indicate that
the back is used for locomotion with these insects more than has perhaps been suspected.

OTTAWA FIELD-NATURALISTS’ CLUB.

We are glad to learn that the Naturalists resident in Ottawa have organized under
the above heading, with the avowed object of paying special attention to the Natural
History of the Ottawa District. The Club is under the patronage of His Excellency the
Governor-General, and has an efficient staff of officers ; among whom we observe the names
of two of our esteemed contributors, J. Fletcher and W. H. Harrington, both enthusiastic
Entomologists, and we are pleased to see Entomology so well represented in this connec-
tion. It is intended to have occasional excursions during the summer, and evening meet-
ings during the winter for the pursuit and discussion of Natural History subjects. Al-
ready the Club has had one very successful excursion, the party numbering in all, ladies
- and gentlemen, about forty. We should like to see such clubs organized in every city in
our Dominion. There is a growing fondness for this interesting study, especially among
our young people, and a little stimulus of this sort would materially aid in developing it.

OBITUARY NOTICES.
W. V. ANDREWS.

It becomes our painful duty to announce the death of one of our correspondents, Mr.
W. V. Andrews, of Brooklyn, N. Y., who died on the 20th of October, 1878, after a brief
illness, resulting from a sudden attack of paralysis.

36

William Valentine Andrews, was born on the 11th of February, 1811, in Pilton,
Somerset, England. At an early age he entered the British service, and served as a pri-
vate in the Coldstream Guards, rising eventually to the rank of Captain. Subsequently
he resigned his commission and removed to Canada, where he resided for several years
in London, Ont., engaged in the book and periodical business. From thence he removed to
the United States and settled in Brooklyn, where he spent the last few years of his life
in the same branch of business, devoting his leisure time chiefly to the study of Entomo-
logy, in which he made rapid progress. He had a well arranged collection of Coleoptera
and Lepidoptera, and a small but well selected library of Entomological works. His re-
mains were interred at Rosedale Cemetery, New Jersey.

Since his decease his collections and library have been purchased by Mr. John
Akhurst, of Brooklyn, N. Y.

FREDERICK SMITH.

Another veteran in the Entomological ranks has passed to his rest. Frederick Smith,
the renowned English Hymenopterist, is no more ; he died on the 16th of February, in
the 74th year of his age, from exhaustion consequent on a painful and dangerous surgical
operation. He was born in London, England, in 1805, and in early life was apprenticed
to Mr. W. B. Cooke, an eminent landscape engraver, where he acquired a very thorough
knowledge of the engraver’s art, which was of great use to him in after life. While still
a young man he became an ardent collector of bees and ants, and also devoted some at-
tention to the collecting of Coleoptera ; but it was not until 1837 that the first paper from
his pen was published, giving an account of the natural history of one of the Gall Flies.
From 1842 to the time of his death his publications were very numerous and of great
value. A most industrious man, a painstaking and methodical student, and an accurate
observer, he has done very much to advance our knowledge of the Order in which he
especially laboured. By his death Entomology loses a sincere and talented advocate and
an earnest votary, and Entomologists will greatly miss a friend who was ever ready to
impart his knowledge to others.

Unitep States ENTOMOLOGICAL COMMISSION.

The Entomologists composing this commission have during 1879 devoted their
attention mainly to an investigation in reference to the Hessian Fly, an insect which has
entailed untold losses on the agricultural community both in this country and the United
States. Early in the year the following circular was issued and widely distributed among
Entomologists and farmers. A large amount of information has in this manner been
gathered and we look forward with much interest to the appearance of the report on this
important subject.

DEPARTMENT OF THE INTERIOR—OFFICE OF THE U. S. ENTOMOLOGICAL COMMISSION.
Providence, R. L., June, 1879.

Dear Sir,—The Commission desires your co-operation in obtaining facts concerning
the habits of the Hessian Fly, with statistics of losses occasioned in your town or county
by its attacks ; and accounts of the remedies best calculated to prevent its increase, and
to destroy it. In brief the habits of the Hessian Fly are as follows: In May and June
two or three small reddish-white maggots may be found embedded in the crown of the
roots of the wheat, at or near the surface of the soil, causing the stalks and leaves to
wither and die ; the maggots harden, turn brown, then resembling a flax-seed, and change
into little black midges with smoky wings, half the size of a mosquito, which appear in
spring and autumn, and lay from twenty to thirty eggs in a crease in the leaf of the
young plant. Specimens of the fly may be obtained by sweeping the wheat when three
or four inches high, with a gauze net. Please send me specimens of the fly, eggs, maggot

37

and ‘‘flax-seed,” in vials of alcohol, which notes as to the date when found, and full
information as to the insect enemies and parasites.

The Wheat Midge is apt to be confounded with the Hessian Fly. It is a small,
mosquito-like fly, orange yellow, with clear wings, which hovers over fields of young
wheat in June. It attacks the heads of the wheat, laying its eggs when the wheat is in
blossom. On hatching, the maggots crowd around the young kernels of wheat, causing
them to become shrivelled. The maggots in July and August descend into the ground,
spinning a round cocoon smaller than a mustard seed, remaining an inch below the
surface till the following June.

Information regarding the following topics is respectfully solicited ; to be forwarded
at the close of the season :

1. When, where, and how are the eggs deposited 1

2. When does the maggot appear ?

3. When is the “ flax seed” state of the Hessian Fly, or the seed-like cocoons of the
Wheat Midge assumed ?

4, At what date do the Midges appear in spring and autumn?

5. Look for minute parasites in the eggs and maggots. They may be bred by
placing the eggs and maggots with the wheat in bottles covered with gauze, and the
parasitic flies preserved in vials of alcohol,

6. Give statistics as to abundance and losses in your town.

7. State the best preventive remedies, as deep ploughing or burning in the fall, or
the rotation of crops.

Specimens of wheat affected by these insects, and of the eggs, maggots and flies,
together with their parasites, in alcohol, are requested. When mailed, the alcohol can
be poured out, and cotton soaked in alcohol will keep the specimens wet until received.
Packed in a tin box they can be sent through the mail. Address as below.

Respectfully yours,
A. 8. Packarp, Jr., Providence, R.I.

CANADIAN CUT-WORMS.
By G. J. Bowies, Montreal.

The term ‘Cut-worm” is popularly applied to certain caterpillars or larvae which
have the habit of cutting the stems of young plants, either just above or just below the
surface of the ground. The name is also often given to the larva of the May-beetle, (the
white grub,”) and to wire-worms, &c.; but it is especially appropriate to the caterpillars
of some of the night moths belonging to the genera Agrotis, Hadena, Mamestra, &c., which
are noted for the destructive habit above referred to.

In Europe there are many species of these insects, which at times prove very injurious
to vegetation. Some despoil the fields of wheat and other grains, others attack the vine-
yards, others again devastate the meadows, while others do great damage to root crops
and garden vegetables. These belong principally to the genus Agrotis, and in the same
genus are placed several of the American moths which produce our cut-worms.

The natural history of these worms is thus given by Mr. Riley, in his first Report,
(Missouri) :

“The parent moth attaches her eggs to some substance near the ground, or deposits
them on plants, mostly during the latter part of summer, though occasionally in the
spring of the year. Those which are deposited during late summer, hatch early in the
fall, and the young worms, crawling into the ground, feed upon the tender roots and
shoots of herbaceous plants. At this time of the year, the worms being small and their
food plentiful, the damage they do is seldom noticed. On the approach of winter they
are usually about two-thirds grown, when they descend deeper into the ground, and,

38

curling themselves up, remain torpid until the following spring. When spring returns,
they are quite ravenous, and their cutting propensities having fully developed, they ascend
to the surface and attack the first green succulent vegetation that comes in their way.
When full grown they descend deeper into the earth, and form for themselves oval
chambers, in which they change to chrysalids. In this state they remain from two to
four weeks, and finally come forth during June, July and August as moths, the chrysalis
skin, being in most cases so thin, that it is impossible to preserve it. These moths in
time lay eggs, and their progeny goes through the same cycle of changes.”

The worms vary in size and markings, but they are all smooth, naked, and greasy
looking, and are of some shade of green, grey, brown or black, with a polished, scaly
head, anil a shield of the same colour on the top of the first paul last segments ; while
most of them have several minute shiny spots on the other segments, each spot giving
rise to a minute stiff hair. They also have the habit of curling up when disturbed.

The moths are of sombre colours, and fly generally at night, often entering lighted
rooms, even in large cities. The upper wings always have two more or less distinctly
marked spots, one round, the other kidney-shaped, and the lower wings are generally grey
or white, without spots.

The history of American Cut-worms has engaged the attention of some of our best
entomologists: —Fitch, Harris and Riley, amongst others, have studied them closely; the
last mentioned, however, being the only one who has fully surmounted the natural diffi-
culties in the way of rearing the larvee, caused by their restless and peculiar habits. In
the Report already quoted, Mr. Riley has given the life history of ten species, all of which
are found in Canada, and as a knowledge of the habits of our species is of considerable
importance to our people, I shall briefly notice in detail those which are most numerous
and destructive.

As to the injuries caused by these caterpillars, they are so well known that it is hardly
necessary to recapitulate them. It is chiefly during May and June that they are found
to be most destructive, at the time when the young corn and other plants are a few inches
high, and the stems of cabbages and other garden vegetables are young and succulent.
Even the flower garden suffers from their attacks, and our balsams, pinks and other flowers,
are ruthlessly destroyed by them. And (what is of more interest to our fruit-growers)
some species (which are also found in Canada) have the habit in early spring, of ascending
fruit trees and destroying the young buds, both cf the leaves and blossoms, thus disappoint-
ing the hopes of the fruit-grower, and sometimes killing the trees.

AGROTIS DEVASTATOR.—Brace.

The Devastating Dart Moth—Larva—The Glassy Cut-worm.—Riley.

This is one of the most common of our Cut-worm moths, and is distributed over a
wide area, being not only found in Canada, but alsofall over the Northern and Western
United States.

The eggs are doubtless laid in the autumn, as when the worms are found in
May, they are nearly full grown. Mr. Riley calls it the “Glassy Cut-worm,” from its
translucent glassy green body, in contrast with a very distinct hard polished dark brown
shield on the first segment, and a bright venetian-red head. There are several small
spots on on segment of the body, and it is very sparsely studded with hairs.

! This Caterpillar, figure 2. after Riley, is the ‘ Cabbage Cut-
<< worm” of Harris, “and often does great injury in gardens.
“& Their depredations are carried on ‘for four or five weeks
in May and June, and they appear as moths from the latter
part of June until September. The larva feeds on wild
plants as well as cultivated, for Mr. Riley found the
specimen from which he reared the moth, “under a wild —
endive plant, on the leaves of which it had evidently been —
Fig. 2. feeding.”

The moth is about 1{ inches across the wings; the fore wings are dark ashen grey,
with a satiny lustre, and are crossed by four narrow wavy whitish bands, edged on each
side with black, there is a transverse row of white dots, followed by a row of black,
arrow-headed spots between third and fourth bands, and three white dots on the outer
edge near the tip; the ordinary spots are edged with black and white, and there is a third
spot of oval shape and blackish colour, near the middle of the wing and touching the
second band. The hind wings are light brownish grey, with a blackish border. (H arris)
As is usual with moths of this genus, there is considerable variation in the intensity of
these markings.

AGROTIS TESSELATA.—Harvris.

The Checkered Rustic Moth—Larva—The Striped Cut-worm.—Fitch.

Common in Canada and the Northern States. This moth is evidently the same as
that so fully described by Dr. Fitch in his Ninth Report (New York), as Agrotis nigricans
Linn. variety maizi. The worm is notorious for its depredations in cornfields, as the name
—maizi—given to it by Dr. Fitch, indicates. It cuts off the plant about half an inch or an
inch above the surface of the ground, and thus many of the plants, though severed, may
survive the injury, and send up new leaves from the stump.

The striped Cut-worm, as Fitch calls it, is from an inch to an inch and a half in length.
Tts ground colour is dirty white or ash grey, sometimes tinged with yellowish, the shield
on top of first segment is shining black, with three whitish longitudinal stripes, a whit-
ish line along middle of back, between two black ones, and on each side of the body three
dark and two pale stripes, sometimes another whitish stripe below the lowest dark one,
and all the under part of the body pale white. Head black with a white stripe along the
middle. (Fitch).

These worms attack the corn during the month of June, and after changing to chrysa-
lids in the ground, come forth in the moth state from the middle of July to the end of
August.

The moth is about 1} inch. in expanse, and is dark ash coloured, with but faint traces
of the ordinary bands. It may be easily identified by the two ordinary spots on the fore
wings being large and pale, and separated by a square black spot. There is also a trian-
gular black spot in advance of the smaller pale spot, and a small black spot near the base
of the wing. The hind wings are brownish grey, with a blackish border. It is a variable
insect.

HapeEna Arctica.—Boisduval.
Hadena amica.—Harris. Hadena amputatric.—Fitch.
Larva—The Yellow-headed Cut-worm.— Fitch.

Very common in Canada, East and West, also over the northern United States. It
is a larger moth than those previously described, and has greater pretentions to beauty.

This is another of the Corn Cut-worm moths. Dr. Fitch has named the caterpillar
the Yellow-headed Cut-worm, and describes it and its habits at great length in his Ninth
Report. The worm is of asmoky or livid brown colour, with a yellow or chestnut coloured
head, and a horny shield of the same colour on the first and last segments of the body. It
grows toa larger size than other Cut-worms, and is peculiarly destructive because it severs
the plant about an inch below the surface of the ground, thus destroying it irremediably.
They also attack the corn till a later period than the preceding species.

According to Harris, this worm has also the habit of climbing bushes and young trees,
to devour the buds, thus combining the habits of the ordinary Cut-worms with those of the
climbing species described by Mr. Riley.

The moth appears during July and August, and is a large one, measuring nearly two
inches across the expanded wings. The fore-wings are of a deep spanish brown, variegated
with grey. The small ordinary spot has a grey border. The kidney spot is large, grey,

40

—— a

and very conspicious. There is a broad wavy pearl-grey or blue-grey band across the
hinder part of the fore wings, and also a narrow wavy band between the oval spot and
the shoulder. The hind wings are ash-coloured, with brownish margins, and have a pale
border, and a central blackish spot underneath. The body is brown and rust-red
Harris). The moth flies at night and often enters lighted rooms in the evening.

AGROTIS TELIFERA.—Harris.

The Lance Rustic—Larva—The Greasy Cut-worm.—Riley.

Very common in Canada, from June until October ; and also at least as far west as
Missouri.

The greasy cut-worm, when full-grown is about one inch and a half in length, and
generally of a dull leaden brown, sometimes inclining to black. It has a faint dirty
yellowish line along the back, a more distinct one on each side, and below each of these,
two other indistinct pale lines. It has also eight or nine black shiny spots on each
segment ; the head is light brown with a dark spot on each side, and dark brown above,
and the shield on neck is dark brown, except a stripe above on each side. The sides and
posterior portions of the body are studded with short white bristles.

This worm is one of the most injurious of its kind, possessing the cutting propensity
in a very marked degree. In the Western States it is extremely destructive to corn,
tomatoes, tobacco, and many other cultivated plants, cutting them off about an inch above
the ground, and attacking plants of quite a large growth. It seems to act almost from
mere wantonness, one worm often ruining ‘several plants in a single night, by severing
them one after the other. It is a very general feeder, and will thrive on apple or grape
leaves, when it can get nothing else.

The moth, figure 3, (after Riley) first described by Harris,
4 is rather a large insect, being about one and a half inches in
g expanse. It closely resembles the Agrotis suffusa of Europe,
8 somuchso that Mr. Norman in his list of Canadian Noctuide
(Can. Ent. 1875) calls it by the latter name. (Mr Grote,
in his Check List, places both these names as synonyms, and
calls the moth Agrotis ypsilon, Rott.) The following is the
description by Harris:—The fore wings are light brown,

t shaded with dark brown along the outer thick edge ; and in
Fig. 3. the middle also in the female ; these wings are divided into
three nearly equal parts by two transverse bands, each composed of two wavy dark brown
lines ; in the middle space are situated the two ordinary spots, together with a third oval
spot, which touches the anterior band ; these spots-are encircled with dark brown, and
the kidney spot bears a dark-brown lance-shaped mark on its hinder part; (whence the
name of the moth), the hindmost third of the wing is crossed by a broad pale brown band,
and is ornamented by a narrow wavy or festooned line, and several small blackish spots.
near the margin. The hind wings are pearly white, and semi-transparent, shaded behind
and veined with dusky brown.

Mr. Riley states that he found the worms two thirds grown on the 22nd of May, and
that it becomes a chrysalis at the end of that month, though the moth does not make its.
appearancce (in Missouri) until July. Mr. Norman’s note on the species is: ‘ Swarming
at sugar, flowers and light, from 2nd June until October.” I myself took a fine fresh
specimen this year at Montreal, on the lst October, at sugar. These facts seem to indi-
late that there are two broods of the insect each year, if not more.

AGROTIS suBGoTHICA.—Haworth.

The Gothic Dart Moth—Larva—The Western Striped Cut-worm.—Riley.

Common in Canada, and the Northern and Western States. It was first described
in the year 1810 by Mr. Haworth, and is supposed to be an English insect ; but as it is

41

quite rare in England, and very common in America, Dr. Fitch and Mr. Riley are of the
opinion that it is an American Insect, the eggs or larve of which have been accidentally
carried to England.

The caterpillar of this moth much resembles that of Agrotis tesselata, described on a
previous page. The ground colour isa dirty white or ash-grey, and it has three broad
dark lines and two light narrow ones on the sides, and a light line edged on each side by
a dark one along the centre of the back. The head is black. Mr. Riley, (who describes
the worms as above), found them in an orchard and gives them the name of the
“ Western Striped Cut-worm.”

Their habits are not yet clearly made out but they are probably similar to those of
the next mentioned species, which Mr. Riley considers distinct, but Mr. Grote looks
upon as identical.

The markings of the moth are very conspicuous
and somewhat resemble those of Agrotis tesselata.
In figure 4 a represents the moth with the wings
expanded, 6 with the wings closed. The fore-
wings are greyish brown along the front edge,
the two spots are of the same colour, and the
black intermediate spot, which is square in fessa-
lata, is rhomboidal in this species, and joined to
the triangular spot on the inner side. There is
also a large black spot below the kidney-shaped

a. Fig. 4. b. one, and a long blackish dash, extending from
the base of the wing, about half-way down the wing near the inner edge, divided into
three spots by two narrow diagonal brown lines. Between this dash and the series of
spots near the outer edge of the wing is a light brown stripe, narrowest at the base. The
insect expands about an inch and a half, and appears during August and September.

AGROTIS JACULIFERA.—Guenee.
The Dart-bearing Rustic Moth—Larva—The Dingy Cut-worm—Riley.

Mr. Riley has reared this insect from a cut-worm, which differs from that of the pre-
ceding species, (subgothica) only in the following particulars: It is never so large, it is
generally darker and of a more dingy colour, the longitudinal lines are less distinct, and
the back is of a more decided pale buff. The worms were found in the garden, and the
species had proved quite destructive in the vicinity.

The moth, like its very near relation, is common in Canada and appears in August
and September. The wings are marked in almost exactly the same way as subgothica,
but are much brighter in colour, although the larva is so much more dingy in appearance
than that of the former species. The lighter parts of the fore wings are almost silvery,
instead of brown, and the darker parts of a more decided black. The inner edge of the
' wing is also much lighter. Mr. Riley also states that the chrysalis differs from most of
the others in being of a very light honey yellow, shaded with brown. The moth is taken
in July, August, and September.

AGROTIS INERMIS.—Harris.
The Unarmed Rustic Moth—Larva—The Variegated Cut-worm.—Riley.

Common over Canada, the Northern and Western States. This moth is one of the
largest of its genus, and so closely resembles the Agrotis saucia of Europe, that many
entomologists consider them identical.

We are indebted to Mr. Riley for a lengthened history of the insect, comprising
many interesting details. The caterpillar, (which he calls the ‘‘ Variegated Cut-worm ”) is,
when full grown, nearly two inches inlength. 1+ is mottled with dull flesh colour, brown
and black, and has elongated velvety black marks on each side of the body. ‘The head is

42

light grey and mottled. The worm isa very general feeder, thriving on cabbage and
grape-vine leaves, and even on the wild mulberry ; while some which had hatched in a
drawer, were found in a half grown state, having fed entirely on some apples which
happened to be in it at the time. The eggs of the insect have been found early in
Spring on cherry and apple twigs, and also on the leaves of the white mulberry, near St.
Louis, Missouri. This fact leads Mr. Riley to think that, in the Western States, the
moth is double brooded, as these eggs must have been laid by a female, which had passed
the winter either in the chrysalis or moth state, and the transformations of the insect are
completed by the spring brood in about thirty-five days. In Missouri the moths
appear during the latter part of June, which would allow ample time for a second brood
before winter. In Ontario, Mr. Norman records the capture of the moth on the 14th
August.

The worms have the climbing faculty to some extent, lying concealed during the day
under the surface of the ground, and ascending vines and other plants during the night
for the purpose of feeding.

The moth expands about 1? inches, and is marked as follows: The fore wings are
light brown, shaded in the middle and towards the hinder margin with dusky brown ;
they are crossed by four more or less distinct, wavy bands, each formed of two blackish
lines ; the kidney-spot is dusky ; and there are several blackish spots on the outer thick
edge of the wing. The hind wings are pearly white in the middle, shaded behind and
veined with dusky brown. ‘The thorax is reddish brown, with the collar and shoulder-
covers doubly edged with black. The abdomen is grey (Harris). It is a very variable
species, as regards the depth of colour.

AcroTis MEssoriA.—Harris. Toe Reapina Rustic Morus.
Agrotis Cochranii (2) Riley—Larva.—The Dark-sided Cut-worm.—Riley.

This moth is described by Harris as the American representative of the Corn Rustic
(Agrotis segetum) of Europe. It is in the list of the Entomological Society of Ontario,
but I cannot say whether it is abundant in Canada or not. It is found in the Province
of Quebec, but is not common.

Mr. Riley has described a moth under the name of Agrotis Cochranii, which Mr.
Grote considers to be the same as messoria. In case they should prove to be identical, I
give some extracts from Mr. Riley’s very valuable article on Cochranii, on account of
the peculiar habits of the larve, a knowledge of which is important to our fruit-growers.

The Caterpillar is one of the “climbers,” and does great injury to the orchards in
Michigan, and States further west, being most injurious in those growing upon light, sandy
soils. The general colour of the worm is dingy ash-grey, bnt it is characterized more
especially by the sides being darker than the rest of the body. When young, it is much
darker, and the white, which is below the lateral band, is then cream-coloured and very
distinct. It grows to a little more than an inch in length. (Rdey.)

The following graphic account of the depredations of this caterpillar is from the pen
of Mr. Cochran, of Calumet, Illinois; and is commended to the notice of the fruit
growers of Ontario.

“Tn the beginning of the evening its activity is wonderful; moving along from limb to
limb swiftly, and selecting at first only the blossom buds, to one of which having fastened, it
does not let go its hold until the entire head is eaten out, and from this point, so thorough
is its work, no latent or adventitious bud will ever again push. From a six-year old fruit
tree, I have, on a single night, taken seventy-five of these worms, and on the ensuing
evening, found them well nigh as plenty on the same tree. When all the blossom buds
of a tree are taken, it attacks with equal avidity the leaf buds. It is no unusual thing to
find small trees with every bud that had pushed, from first intentions utterly destroyed,
and frequently young orchards the first season planted, on sandy grounds, lose from 50
to 75 per cent. of their trees; sometimes those remaining will be so badly injured as to
linger along a few years, fruiting prematurely each season, and then die, utterly drained

43

of their vital principle by this dreadful enemy. = sf is It is far more
destructive to fruit trees than any other insect, infinitely more so than the canker-worm,
but unlike the other depredators of our orchard trees, it is easily kept in check, and at
small expense permanently eradicated.”

Figure 5 (after Riley), represents both the
larva and perfect state of this insect. The moths
appear during July and August, and expand about
an inch and a half.

Mr. Harris describes messoria as follows:—
“The fore wings are reddish gray, crossed by
five wavy blackish bands, the first two of which,
and generally the fourth also, are double; the

Fig. 5. two ordinary spots, and a third oval spot near the
middle of the wing, are bordered with black. The hind wings are whitish, becoming dusky
brown behind, and ,have a small central crescent and the veins dusky. The head and
thorax are chinchilla-grey; the collar is edged with black; and the abodomen is light
brownish-gray.”

AGROTIS SCANDENS.— Riley.

The Climbing Rustic Moth—Larva—The Climbing Cut-worm.—Riley.

This moth, described by Mr. Riley in his First Report, is also on the list of the
Entomological Society of Ontario. It is very common in the Western States, and the
larva is very injurious to apple and other fruit trees, devouring the blossom and leaf buds
in early spring, in the same manner as the species last described.

Even though it may not be common in Ontario, a knowledge of its habits is necessary,
as our fruit-growers are often not aware of the reason why so many of their trees dwindle
away and at last perish; and in many cases the loss may be caused by the attacks of this
cut-worm, or others of similar habits.

The full-grown worm is nearly an inch and a half in length, and of a very light yel-
lowish grey colour, variegated with dirty bluish green spots, and when filled with food it
has a much greener appearance than at other times. In depth of shading, however, it is
variable; and the young worm is of a more uniform dirty whitish yellow, with the lines
along the body less distinct, but the shining spots more so than in the full-grown ones.
There is a well-defined line along the back, and two lines along each side, less distinctly
marked. The head and shield in first segment are tawny; the latter has a small black
spot on each side, and the head has two in front and two eye spots on each side. (Riley).

The following is an account of its habits:—They hide under the surface of the ground
- during the day, but soon after dark begin ascending the trees to feed, remaining there the
greater part of the night. When filled with food, they seem to suspend themselves to the
limb by a thread, and drop to the ground. They seem to commence with the terminal
buds, and when these are all gone, betake themselves to the side buds, thoroughly destroy-
ing all that they attack, so that the tree, if a small one, is often fatally injured. Apple,
pear, peach and cherry trees are subject to their attacks and they are also very partial to
grape vines. Like the preceding species, they are most abundant in orchards growing on
light soils, and less frequent as the soil is more clayey; the light soil affording them easier
access for purposes of concealment during the daytime. ,

The worms appear early in spring, and descend into the earth to become chrysalids
about the end of May, coming forth as moths during June and July.

The perfect insect is about an inch and a half in alar expanse, the fore wings are a
light pearly bluish grey, deepening towards the hind margin, and the hind wings are pearly
white. The usual markings are generally indistinct, with the exception of the kidney
spot and sub-terminal line. A black stain at the lower part of this spot forms a most dis-
dinctive character, but the peculiar colour of the moth easily separates it from other species
of its genus. At the same time it is, like nearly all the Agrotide, somewhat variable in
colour.

4A,

AGROTIS CLANDESTINA.— Harris.
The Clandestine Owlet Moth—Larva—The W Marked Cut-worm.—Riley.

Very common in Canada, the Northern and Western United States.

; The larva of this moth fig. 6 (after Riley) is one of the climbers,
but does not possess the habit toa marked degree. Though it has
j= been caught eating apple buds, it seems to prefer low bushels, such as
== currants, ~&e., and its more congenial food is garden vegetab es. The
bill of iadicuments against this worm is a heavy one, as ithas been

Fig. 6. found to attack wheat, young corn, buckwheat, young pumpkins, beans,
cabbages, and many other garden plants. In feeding, it frequently drags its food under
stones or into the ground, so that it may devour it at leisure.

The general colour of the worm is ash grey, inclining on the back and upper sides to
dirty yellow, and it is finely speckled over with black and brown spots. Along the back
is a fine light line, a light sulphur yellow line on each side, with a band of dir ty brownish
yellow beneath. The distinguishing feature is a row of black velv ety marks along each
side of the back, on all but the thoracic segments, and bearing a general resemblance, look-
ing from tail to head, to the letter W, whence Mr. Riley has given it its name. Head
black, with a white line in front like an inverted Y, and white at sides. It is about 14
inches in length. (Riley.)

The moth appears at the end of June. It is dark ash grey, with the usual wavy
bands faintly traced. The two ordinary spots are small, narrow, and generally connected
by a fine black line. The hind wings are dirty brownish white, somewhat darker behind.
It expands about an inch and three-quarters. The wings, when closed, overlap on their
inner edges, and cover the top of the back so flatly and closely that the insects can get
into very narrow crevices. During the day they hide under the bark of trees in the
chinks of fences, or the clapboarding of buildings. This peculiarity led Harris to give the
moth its specific name of clandestina.

HADENA SsuBJUNCTA.—Grote and Robinson.

The Subjoined Hadena—Larva—The Speckled Cut-worm.—Riley.

This moth, placed by Mr. Riley among the Cut-worm moths of Missouri, is also found
in Canada. The caterpillar, when full grown, is about an inch and a half long, grey, with
a tinge of rust colour on the middle of each segment, and is minutely speckled as with
pepper and salt. It has an interrupted white line on the back with a similar one on
each side and two spots on the back on the fore part of each segment. The head is light
shiny brown. It feeds voraciously on cabbage leaves during the night, lying concealed .
and motionless in daytime.

The moths appear early in August, and are very distinct in appearance from those
already described. They are of a dull flesh-coloured shade, marked with greyish brown
and black. The ordinary spots are large, with a distinctly marked ring around them ;
and the abdomen is crested at the base. A full description of the insect is given by Mr.
Riley, in his first Report, page 85, which is copied from that of Messrs. Grote and Robin-
son. It is not very common in Canada.

CELENA RENIGERA.—Stephens. CO. HERBIMACULA.—Guenee.
The Figure 8 Minor—Larva—The Small White Bristly Cut-worm.—Riley.

The moth bearing this name isa pretty little insect, the fore wings being brown,
variegated with lilac-grey, and mossy-green, and having a deep brown spot about the
middle, and a silvery line, somewhat resembling the figure 8, around the kidney spot. It
is much smaller than those previously mentioned, and has the wings broader and rounder
in proportion.

45

The full-grown larva is a dirty-white cut-worm, about three-fourths of an inch long,
covered with stiff yellow bristles, and is often found in flower gardens, where it is sup-
posed to feed on the roots of flowers. During August it becomes a chrysalis in the
ground, from which it issues as a moth in September, according to Mr, Riley, but Mr.
Norman (Canadian Eutomologist, 1875) records it as very common at St. Catherines,
Ontario, from 23rd June until October, and thinks there are two if not more broods of the
insect each year.

OTHER CUT-WORMS.

In the preceding pages we have noticed twelve species of these caterpillars, the his-
tories of which have been studied out. The reader will acknowledge that practical Ento-
mology is deeply indebted to Mr. Riley, when it is stated that ten of these histories are
the result of his researches. No doubt there are others which are injurious, but their
economy is yet unknown. Among these is one which Mr. Riley calls the “‘ wheat cut-
worm,” the moth of which he has not, as yet, succeeded in rearing. He gives an account
of it in his first report, and it may, perhaps, be found in Canada.

REMEDIES AGAINST CUT-WORMS.

Naturaut..—The means which nature has provided to check the increase of these
worms, are, as In other cases, the attacks of predatory insects. Some of our well-known
friends, belonging to the beetle, bug and ichneumon tribes, prey upon them and do good
service. One of the most efficient is the larva of the fiery ground beetle (Calosoma
calidum, Fabr.), which has been styled the “ cut-worm lion,” on account of the energy and
activity it displays in hunting them. The larva is a flattened, black worm-like creature,
with six legs on the fore part of the body, and a pair of sharp hook-like jaws projecting
from the head, giving it quite a formidable appearance. It seeks the cut-worms even
under the soil, and when it discovers one, fixes its jaws in the worm’s throat with the
grip and pertinacity of a bull dog, never letting go its hold until the larva succumbs and
dies. It then feeds upon the contents of the body, and after a rest, goes in pursuit of a
fresh victim.

Another beetle which preys upon them is the murky ground bettle (Harpalus cali-
ginosus, Say.), and several others of the Carabidae are known to have similar habits.

Among the bugs, the spined soldier bug (Arma spinosa, Dallas) devours the worms
bodily, and is very serviceable in thinning the numbers.

There are also several of the Hymenoptera, which in the larva state live internally
upon them, producing four-winged flies, some very small (A/iciogaster), others quite large,
as the yellowish brown Ichnumeon, (Paniscus geminatus, Say.)

Poultry, particularly chickens, are also an efficient help in destroying them.

ArtiFiciAL.—In order to keep cut-worms in check by artificial means, a knowledge of
their habits is essential. Thus we know that they always feed at night, and in the day
time conceal themselves under, but near the surface of the ground, in the immediate
vicinity of the plants they have attacked. A slight search is sure to reveal them, and
when found they are of course easily destroyed. This, though troublesome, is the most
efficacious mode of preventing their ravages.

Ashes and lime spread around the plants have been recommended, but their usefulness
is questionable. Soot seems to be more obnoxious to them. Fall ploughing is also sup-
posed to be a remedy, and has been extensively practised, but it must be done very late
in the season, when the worms are benumbed with cold, otherwise they will again descend
into the soil to the depth necessary for their protection from the winter.

A curious fact in the history of these worms, is, that they cannot crawl up a perpen-
dicular bank of earth. This fact has been utilized against them, and many have been

46

entrapped in smooth holes made with a stick around the hills of corn or other plants in-
fested by them. Another plan is to strike a single deep furrow with the plough around
the field or garden to be protected, with the land side made perpendicular and without
breaks, thus forming a barrier which they cannot surmount and preventing them from
entering from the adjacent land.

Against the climbing cut-worms, vigilance is the main requirement for success. They
also feed at night, and many may be picked off the trees after dark, with the help of a
lantern. Some other plans have been devised, which are easily tried, and are so lucidly
explained by Mr. Riley, that I add his remarks in full :-—

“From the orchard planted upon light, warm soils, they can be driven away entirely
by claying the ground about the trees ; a wheelbarrow full is well nigh enough for each
tree when spread around its base and as far as the limbs extend. This is the most
thorough and lasting. A small strip of tin, three inches wide, carefully secured around
the body of the tree, will effectually prevent their ascension ; if the tin is old and rusty it
will require to be a little wider. Each night, after the swelling of the bud, an hour or
two after midnight a slight jar of the tree will bring every one on it down, when they
can be caught in a spread sheet and destroyed. This will have to be followed up till the bud has
unfolded into the leaf, after which there is no longer anything to be apprehended from the
worm. ‘The reasons why the clay is so efficient, are two-fold: 1st. The worms seem to have
an instinctive dislike to crawling over it; 2nd. In dropping from the tree on to the hard
surface they are frequently disabled, and whether disabled or not, they cannot iminediately
burrow into it as into sand, and they are all the more exposed to their numerous midnight
enemies, which are ever watching for them.”

SPIDERS.

By THE Rev. C. J. 8S. BETHUNE.

[In the following paper, the writer lays no claim whatever to any originality ; he
has simply endeavoured to compile from various sources an account of the natural history
of spiders that, he trusts, may afford interesting information to the general reader. The
books from which he has mainly drawn his information are Emerton’s “ Structure and
Habits of Spiders,” (Salem, Mass., 1878); Rev. J. G. Woed’s “ Illustrated Natural His-
tory ;’ Kirby & Spence’s ‘‘ Entomology ;” and Mogeridge’s “ Harvesting Ants and Trap-
Door Spiders.” The illustrations are all reproductions of the wood-cuts in Emerton’s
excellent work, for permission to use which he is indebted to the publisher, Mr. 8. E.
Cassino, of Salem. |

1,—INTRODUCTORY.

What is a SprpER? is the first question that naturally arises when we begin to talk
about the life-history of the class. Most persons would probably reply at once that a
spider is an insect. This is undoubtedly correct in the popular acceptation of the term
insect, and also accords with the derivation of the word (Latin— in and seco, I cut), sig-
nifying an animal whose body is divided into two or more segments almost entirely
detached from each other. Spiders, however, are not true insects, though they belong to
the same great division of the animal kingdom called the Articulata. As we stated in a
former Report (1872, “ Beneficial Insects,” page 427), insects are distinguished by the
following characteristics :—Ist. They have their bodies divided into segments. 2nd. They ~
breathe through openings in their sides (spiracles) from which proceed trachee or wind-
pipes. 3rd. They have distinct heads, with jointed antenne, or feelers. 4th. When
adult they have six articulated legs. 5th. They go through a series of metamorphoses,

47

ending in a winged state. A spider differs from an insect in almost all these particulars:
Ist. It is divided into only two segments. 2nd. It breathes, as a rule, through sacs in
the abdomen. 3rd. It has no distinct head separate from the thorax, and possesses no
antenne. 4th. It has eight articulated legs. 5th. It undergoes no distinct metamor-
phoses, and never attains wings. On all these accounts, then, we cannot scientifically call
a spider an insect, though it is often convenient to use the term in ordinary conversation.
A spider technichally belongs to the class Arachnida, which includes also the scorpions
and mites ; from the two latter orders it is distinguished especially by its spinning organs
and its faculty of making cobwebs and silk cocoons for its eggs.

2.—ANATOMY.*

The common round-web spider, Lpeira vulgaris, Hentz, will serve as well as
any other species to show the anatomy of spiders in general. Figure 7 shows the
under side of the spider; Figure 10 the upper
side ; and Figure 11 an imaginary section through
the body, to show the arrangement of the inter-
nal organs. To begin with Figure 7, the body is
seen to be divided into two parts connected only
by the marrow joint, A, just behind the last pair
of legs. The front half of the body, called the
Thorax, contains the stomach, the central part of
the nervous system, and the large muscles which
work the legs and jaws. The hinder half, the
Abdomen, contains the intestine, the breathing
organs, the principal circulating-vessels, the or-
gans of reproduction, and the spinning-organs.
Connected with the thorax are six pairs of limbs,
four pairs of legs, B B B B, a pair of palpi, C,
and a pair of mandibles, D.

The Legs are used chiefly for running, jumping
and climbing ; but the front pair serve often as
feelers, being held up before the body, while the
spider walks steadily enough on the other six.
One or both of the hinder legs are used to guide
the thread in spinning; the spider at the same
time walking or climbing about with the other six
or seven. The legs,are seven-jointed; and on
) the terminal joints are three claws, Fig. 8, A, B,
C, and various hairs and spines. In many spi-
ders a brush of hairs takes the plac? of the middle
claw, as in the jumping-spiders, Fig. 9. Spiders
with these brushes on their feet are able to walk
up a steep surface or under a horizontal one, bet-
ter than those with three claws. The legs of
most spiders have amongst the hairs moveable
spines, which, when the spider is running about,
: extend outward at a right angle with the leg, and

Fig. 7. when it is resting are closed against the skin.

In front of the legs are the Palpi, Fig. 7, C C,—a smaller pair of limbs, with six joints,

and only one claw, or sometimes none. They are used as feelers, and for handling food, and in

sages should they desire to do so. .

the males carry the very
curious palpal organs,
which are employed in
the fertilization of the
female. The basal joints,
Fig. 7, E E, of the palpi
are flattened out, and
serve as chewing organs,
they are called maz-
ile.
The front pair o!
limbs, the Mandibles,
Fig. 7, D D, have two
joints, the basal one is
usually short and stout,

Fig. 8. and furnished on the
inner side with teeth and hairs ; the other is a small, sharp
claw, which can be closed against the basal joint when not
in use. (See also Figures 19 and 20.)

The Abdomen, or hinder half of the body, is furnished, just behind the legs, with two
hard, smooth patches, which cover the front pair of breathing-organs, the openings to
which are two little slits at Fig. 7, H. At the end of the body are the spinnerets, which
will be described futher on. There are three pairs of them ; but many spiders close them
together when not in use, so as to cover up the
middle pair. Sometimes the third pair of
spinnerets have several joints and extend out
behind the body like two tails. In front of the
spinnerets is a little opening, Figure 7, K,
which leads to air-tubes that give off branches
to different parts of the abdomen. At M,
Figure 7, are usually two coloured bands, or
rows of spots, marking the course of muscles
attached to the skin at various points along
these lines.

Let us now turn to figure 10, which repre-
sents the upper surface, or back of the same
spider. The head is not separated from the rest
of the body, as in insects, but forms one piece
with the thorax. On the front of the head are
eight simple eyes, O, which are differently
arranged in different spiders. At the back of
the thorax is a groove, P, under which is at-
tached a muscle for moving the sucking stomach,
Figure 11, D. From this point radiate shallow
zrooves, that follow the divisions between the
auscles of the legs. On the abdomen are
several pairs of dark smooth spots which
mark the ends of muscles extending downward
through the abdomen. The markings of this
spider are very complicated. The spot on the
middle of the front of the abdomen is a very
common one, and in some spiders extends the
whole length of the body. The waved lines on
each side are also common, and in long-bodied
spiders often form two bright-coloured stripes,
or rows of spots, running nearly straight the
whole length of the abdomen.

3.— CLASSIFICATION.

To enter into a minute account of the classification of the Arachnida would be
very tedious, and occupy an undue amount of space. We shall therefore content our-
selves with mentioning some of the wore important families of spiders, and describe
some of their characteristics.

The largest known spiders belong co the family Mygalide. They may be at once
distinguished by the shape of their mandibles and the terrible claws which proceed from
them. In most spiders the claws are set sideways (as in Hpeira Figure 7, D.), but in this
family they are bent downwards, and strike the prey as a lion would clutch his victim

. with his curved talons. The body
is usually very hairy and dark-col-
oured. Most species have only four
Z spinnerets, one pair of which are
long and are turned up behind the
abdomen ; they have four air-sacs
under the front of the abdomen,
instead of two, as other spiders. The
eyes are collected together on the
front of the head. They live only
in warm countries. Figure 12 re-
presents Mygale Hentzii, a species
found in Texas and Arizona. Many
wonderful stories have been told
about the ferocity of these huge
spiders, their power of catching and

mals. These accounts were gener-
ally discredited and looked upon as
mere “ travellers’ tales,” but of late
years fresh evidence has been pro-
duced by naturalists in proof of the
former stories. The following de
scription by Mr. H. W. Bates in his
interesting work, “The Naturalist
on the River Amazon, ” (page 83),
sets forth the truth regarding these
monsters :—

hn Fig. 12

eating small birds and other anti-.

“ At Cameta,” he relates, ‘“‘I chanced to verify a fact relating to the habits of a large
hairy spider of the genus Mygale, in a manner worth recording. The individual was
nearly two inches in length of body, but the legs expanded seven inches, and the entire
body and legs were covered with coarse grey and reddish hairs. I was attracted by a
movement of the monster on a tree-trunk, it was close beneath a deep crevice in the tree,
across which was stretched a dense white web. The lower part of the web was broken,
and two small birds, finches, were entangled in the pieces. One of them was quite dead,
the other lay under the body of the spider not quite dead, and was smeared with the filthy
liquor or saliva exuded by the monster. I drove away the spider and took the birds,
but the second one soon died. I found the circumstance to be quite a novelty to the
residents hereabouts. The Mygales are quite common insects ; some species make their
cells under stones, others form artistic tunnels in the earth, and some build their dens in
the thatch of houses. The natives call them crab spiders. The hairs with which they are
clothed come off when touched and cause a peculiar and almost maddening irritation.
Some Mygales are of immense size. One day I saw the children belonging to an Indian
family who collected for me, with one of these monsters secured by a cord around its waist,
by which they were leading it about the house as they would a dog !”

Other writers relate that the spiders of this family attack humming-birds, lizards,
cockroaches, ants, ete.

The Dysderide constitute a small family of. spiders which are
chiefly remarkable for possessing only six eyes, instead of the normal
number of eight. They are usually found under stones or in holes
in the earth ; they lie with their legs drawn up under them, but-
are able to move very quickly when so inclined. Very few species are
known and none are common in America ; a few have been observed
in Europe.

The family of the Drasside is spread over the greater part of the
world ; they vary very much in shape, colour and habits. Most of
them are dull coloured, while they all have the habit of concealing
themselves in silken cells that they construct under stones, in chinks
of walls, or on plants. They are active creatures, and catch their
prey by chasing them, as they construct no webs. Figure 13 represents
a species of Drassus ; the double row of circles above represents
the mode in which the eight eyes are arranged on the front of the

Hip a3, head. Their feet have two claws and a bunch of flat hairs : the spin-
nerets usually project a little beyond the abdomen.

The <Agalenide are long-
legged, brown spiders, with two
spinnerets longer than the
others and extending out be-
hind the body. Figure 14 re-
presents Agalena novia, the
common grass spider. The
members of this family are very
numerous on grass-fields and
commons, where they made flat
webs with a funnel-shaped tube

Fig. 14, on one side in which the spider
waits, see figure 23. Many of the species are prettily marked ; they lay their eggs in dish- .
shaped cocoons, which are attached to grass or other lrerbage, and are usually covered with
little bits of dead leaves, pieces of earth and other substances in order to conceal them
from enemies.

The next family, Ciniflonide, much resemble the preceding, but are distinguished by
their peculiar spinning organs. They live in crevices in rocks, walls and stones, or
under loose bark, and near their hiding-place they weave nets of a most elaborate
structure, not flat like garden-spiders but enclosing large spaces in comparison with the
small size of the builder. The web is most intricate in its arrangements, and is connected

51
ee oeoeoeaqyqeq$7«zFO0066S0— ——S0S09D9D Sry

with the hiding-place of the spider by means of a silken tunnel, through which the crea-
ture darts when it feels the vibration of an insect in its web, and to the bottom of
which it retreats when danger threatens. The species of this family are very numerous,
building their webs on stone buildings, often to their great disfigurement, in cellars, the
corners of windows, &c. They are, no doubt, familiar to every observer.

The Lycoside, or Wolf-spiders, live on the ground and take their prey in fair chase,
instead of catching it in webs. They are mostly found among herbage, low bushes, fallen
leaves, and similar localities, and if they should feel alarmed, they run for safety under
stones, mosses, rocks, and into any accidental crevice in the
earth. They are fierce and determined hunters, chasing their
prey wherever it may seek shelter. Some of them are
semiaquatic in their habits, and are not only able to run
fearlessly upon the surface of the water, but can descend
along the aquatic plants until they are deeply immersed,
breathing by means of the air which is entangled among the
hairy clothing of their bodies. They have long legs, the hind
pair being the longest; the head is high, and the eyes are
arranged in a peculiar manner, as shown at the bottom of
Fig. 15, which represents a species of Lycosa.

The celebrated Tarantula spider belongs to this genus. It
is so called from the town of Tarentum, in Italy, where it is
very common. There was a deeply rooted belief among the
inhabitants of that town and neighbourhood that if any one
were bitten by this spider, he would be instantly afilicted
with an extraordinary disease called tarentismus, which exhib-

TS. ited itself in one of two extremes, the one being a profound
and silent melancholy, and the other a continual convulsive movement of the whole body.
It was also thought that this disease could only be cured by music, and that a certain
tune was needful in each particular case. The disease undoubtedly existed and spread
with great rapidity through the neighbouring towns and villages, affecting hundreds of
_ both sexes who came within the sphere of its influence, but the poor Tarantula spider had
no more to do with it than the cattle grazing in the fields or the birds chirping in the
trees. It was evidently a nervous disease like chorea and hysteria at the present day,
which tends to propagate itself among all exposed to its influence.

Another species of Lycosa frequents dry and uncultivated soils, and sinks in the
ground a little pit of a depth varying with its size and the length of its residence. The
interior of the cell it strengthens with a web. At the entrance of this burrow it sits
watching for its prey, and as soon as an unfortunate insect passes within range, it darts
forward, seizes it in its talons, and bears the victim away to its den, where it feasts in
peace and solitude.

The females of this genus are extremely fond of their eggs and young. The eggs are
enveloped in silken cocoons of a globular form, which the mother always drags about
with her, bumping them over stones and rough ground without injury to the delicate organ-
isms within. As soon as the young are hatched and emerge from the cocoon, they
transfer themselves to the body of their parent, where they cling in such numbers that
sometimes she is hardly visible under her swarming brood. They remain with their
mother during the winter, and in the following spring disperse to seek their own living.

The Attide, or jumping spiders, are the next on our list of families. The body is usu-
ally short and the head square. The arrangement of the eyes is very peculiar, as they
are set on the head in the form of a semi-circle, with two very large eyes in the middle
of the curve ; this give the spiders of this family a much more animated look than is
usual among the Arachnida. The legs are short, the front pair being often stouter than
the others. They can run easily backwards or sideways as well as forwards, and jump a
long distance. Figure 16 represents the common grey jumping spider (Sa/ticus ) much
magnified. Many of this family of spiders are very common; they are usually found
upon walls, among stones, or under leaves ; a sunny window-sill is also a favourite locality
for them. When one of them sees a fly, or other insect, which it wishes to devour, it

52

sidles along quietly in the direction of its intended victim, keeping a most careful
watch, and ever drawing nearer to its prey. As the fly moves, so moves the spider, until
the two appear to be animated by one common will. Slowly, but surely, it makes its way
towaras the unsuspecting fly, and then with a leap so quick that the eye can scarcely follow
the movement, it springs upon its prey, rolls perhaps over and over, and in a few moments
emerges victorious from the contest,
its victim dead or dying in its grasp..
Even on a_ perpendicular wall the
spider will make these leaps. It is
sure not to fall to the ground as it al-
ways draws a silken cord behind it
as it thoves, and so, whenever it leaps
upon its’ prey, it is able to mount up
again to its former post.

The family Zhomiside, or Crab-
spiders, are like the preceding, depen-
dent for their subsistence upon their
bodily powers and activity. The body
is usually flat, and wide behind. The Fig. 16.
front two pair of legs are longer than the others, and so

bent that the spider can use them when in a narrow crack.

° 4 z ° Some of them, like crabs, walk better sideways than for-

Fig. 17. wards. Like the running and jumping spiders, they

make no webs for catching food. Fig. 17 represents a species of Thomisus, showing at

the bottom of the cut the arrangement in two rows of the eight small eyes. As in
many other families of spiders, the males are very much smaller than the females.

The next family, 7heridiide, contains the largest number of species, but the spiders
comprising it are usually small, with large rounded abdomens and slender legs. They us-
ually live upside down, holding on by their feet to the underside of their webs, as in fig. 18,
which represents the common house Thert-
dion, much enlarged. They make large
cobwebs of different shapes for different
species, and depend for food on what is
caught inthem. They are found in all parts
of the world, and vary very greatly
in their habits. Some live under stones,
others are abundant in houses, hiding
themselves in shady corners, while the greater

commons, spinning their elaborate webs over
Fig. 18. the bushes, trees, or herbage. Their appear-
_ ance and habits must be familiar to every one.

- 4'The last family on our list is the Hpeiride, or round-web spiders ; it contains some of
the strangest members of the race. The individuals are usually large, with flat heads, and
eyes wide apart, and with short round abdomens. The upper and under surfaces of a
eommon species, Lpeira vulgaris, are represented in figs. 7 and 10. They make webs
“formed of radiating lines crossed by other adhesive ones in a spiral or in concentric loops, as
in fig. 24. They live in the web, hanging head downwards, or upside down in a hole
near by. The webs are usually stretched perpendicularly from branch to branch of a tree,
or in the angles of verandahs, fences and other outdoor localities.

4,—Bitine APPARATUS.
E* "wAlmost every one, we imagine, looks upon spiders with a certain degree of abhorrence

on account of the supposed poisonous character of their bite, and the ferocious, blood-
thirsty disposition ascribed to them. The popular opinion regarding them is, no doubt,

number prefer the open air, the fields and

immensely exaggerated ; they do, of course, possess a biting apparatus and a poison —

gland that we shall presently describe, but we do not think they are at all inclined to

~

53

make use of these except against their natural prey, viz., flies and other insects. Though
we have often been shewn marks and swellings on the limbs of children that mothers and
nurses ascribe to spiders, we have never caught a spider in the act of attacking a child,
nor have we found that others have done so. While we do not for a moment deny that
spiders may attack human beings, we should like a little more direct evidence before we
condemn the whole race.

The biting apparatus is shewn in fig. 19,
which represents the head and mandibles of
Epeira vulgaris, seen from in front. When not
in use, the claw is closed up against the mandible
between the rows of teeth ; but, when the jaws
are opened to bite, the claws are turned outward,
so that their points can be stuck into anything
between the jaws. Fig. 20 is the claw still

bs, more enlarged, shewing a little hole near the

Fig. 19. point at a, out of which is discharged the poison-
ous secretion of a gland in the head, fig. 11, ». The ordinary
use of the mandibles is for killing and crushing insects, so that
the soft parts can be eaten by the spider ; and in this they are
‘aided by the maxille, fig. 7, e. They will sometimes chew _ Fig. 20.
an insect for hours, until it becomes a round lump of skin, with all the blood sucked out
of it ; this is then thrown away, the spider swallowing only such bits as may happen to be
sucked in with the liquid portion.

“ Tf let alone”—to quote Emerton—“ no spiders bite anything except insects useful for
food ; but, when attacked and cornered, all species open their, jaws and bite if they can ;
their ability to do so depending on their size and the strength of their jaws. Notwith-
standing the number of stings and pimples that are laid to spiders, undoubted cases of
their biting the human skin are very rare ; and the stories of death, insanity and lameness
from spider-bites, are probably all untrue.”

On the opposite side we may quote the Rev. J.G. Wood, who says: ‘I can state
from personal experience that the bite of an angry spider inflicts a really painful injury,
not very dissimilar to the sting of a wasp. I have seen a lady’s hand and arm swollen
so as to be hardly recognizable as belonging to the human figure, in consequence of a bite
inflicted by a large spider on the back of her hand.”

Many experiments have been tried to test the effect of the bites of spiders on
animals, Doleschall shut up small birds with two species of Mygale, both large and
strong spiders (see fig. 12); and the birds died in a few seconds after being bitten.
One of the spiders was left for ten days without food, and then made to bite another bird,
which was injured, but in six hours recovered. The same author was bitten in the
finger by a jumping spider. The pain was severe for a few minutes, and was followed by
lameness of the finger and gradually of the hand and arm, which soon went away
entirely.

Bertkau allowed spiders to bite his hand. On the ends of the fingers the skin was
too thick, but between the fingers they easily pierced it. The bite swelled and smarted
for a quarter of an hour, and then itched for some time, and for a day after itched when-
ever rubbed, as mosquito bites will. He also experimented on flies, which died in a few
minutes after being bitten.

Mr. Blackwall, to test the poison of spiders, made several large ones bite his hand
and arm, and at the same time pricked himself with a needle. Although the spiders bit
deep enough to draw blood, the effect of their bite was exactly like that of the prick of
the needle. No inflammation or pain followed, and both healed immediately. ‘

Several spiders were placed together, and made to bite one another. The bitten

ones lived always some hours, and died from loss of blood ; and one spider, that had been
bitten in the abdomen so that some of the liver escaped and dried on the outside, lived
over a year, apparently in good health.

A large spider was made to bite a wasp near the base of the right front wing, so as
to disable it: but it lived thirteen hours.

54

A bee was bitten by a large spider, but lived three days.

A grasshopper was bitten, and held in the jaws of a spider for several seconds ; but
it lived in apparent health for two days.

Insects of the same kind were wounded in the same places with needles, and died in
about the same time as those bitten. From these experiments Mr. Blackwall was led to
believe that the secretion from the spider’s jaw is not poisonous, but that insects die,
when bitten, from loss of blood and mechanical injury. 4

Dufour kept a Tarantula that soon learned to take flies from his fingers without bit-
ing him. Spiders of very different species may soon be taught to take food from the
hand or a pair of forceps, or water from a brush, and will come to the mouth of their
bottle and reach after it on tip-toe. Many stories are also told of spiders coming out of
their holes to listen to music, and of their being taught to come out and take food at the
sound of an instrument.

We may quote here the account of an observer of what a spider can eat in a day :—
‘Tn order to test what a spider can do in the way of eating, we arose about daybreak in
the morning to supply his fine web with a fly. At first, however, the spider did not come
from his retreat, so we peeped among the leaves, and there discovered that an earwig had
been caught and was now being feasted on. The spider left the earwig, rolled up the
fly, and at once returned to his “first course.” This was at half-past five a.m. in
September. At seven a.m. the earwig had been demolished, and the spider, after resting
a while, and probably enjoying a nap, came down for the fly, which he had finished at
ninea.m. <A little after nine we supplied him with a daddy-long-legs, which he ate by
noon. At one o'clock a blowfly was greedily seized, and then immediately, with an
appetite apparently no worse for his previous indulgence, he commenced on the blowfly.’

5.—SPInNING APPARATUS.

That, which more than anything else, distinguishes spiders from other animals is the
habit of spinning webs. Some of the mites spin irregular threads on plants, or cocoons
for their eggs ; and many insects spin cocoons in which to pass through the change from
larva to adult. In the spiders, the spinning organs are much more complicated and used
for a greater variety of purposes,—for making egg-cocoons, silk linings to their nests, and
nets for catching insects. The spider’s thread differs from that of insects, in being made
up of a great number of finer threads laid together while soft enough to unite into one.

The external spinning-organs are little two-
jointed tubes on the ends of the spinnerets,
Fig. 7, L. Fig. 21 represents the spinnereés
of the same spider, still more enlarged to shew
the arrangement of the tubes. There isa large
number of little tubes on each spinneret,
and in certain places a few larger ones. Each
tube is the outlet of a separate gland.

When the spider begins a thread it presses
the spinnerets against some object, and forces
out enough of the secretion from each tube to
adhere to it. Then it moves the spinnerets
away ; and the viscid liquid is drawn out and
hardens at once into threads,—one from each
tube. Ifthe spinnerets are kept apart a band
of threads is formed; but if they are closed
together the fine threads unite into one or more
larger ones. If a spider is allowed to attach its thread to glass, the end can be seen
spread out over a surface as large as the ends of the spinnerets, covered with very fine
threads pointing towards the middle where they unite. The spinning is commonly helped
by the hinder feet, which guide the thread and keep it clear of surrounding objects, and
even pull it from the spinnerets. This is well seen when an insect has been caught in a
web, and the spider is trying to tie it up with threads. She goes as near as she safely can,
and draws out a band of fine threads, which she reaches out toward the insect with one of

her hind feet ; so that it may strike the threads as it kicks, and become entangled with
them. As soon as the insect is tied tightly enough to be handled, the spider holds and
turns it over and over with her third pair of feet, while with the fourth pair, she draws
out, hand over hand, the band of fine threads which adhere to the insect, as it turns, and
soon cover it entirely.

It is a common habit with spiders to draw out a thread behind as they walk along ;
and in this way they make the great quantities of threads that sometimes cover a field of
grass or the side of a house. We often see the points of all the pickets of a fence con-
nected by threads spun in this way by spiders running down one picket and up the
next, for no apparent purpose.

Spiders often descend by letting out the thread to which they hang; and are able to
control their speed, and to stop the flow of thread at will. They sometimes hang down
by a thread, and allow themselves to be swung by the wind to a considerable distance, let-
ting out the thread when they feel they are going in the right direction.

Spiders in confinement begin at once to spin, and never seem comfortable till they can
go all over their box without stepping off their web. The running spiders, that make no
other webs, when about to lay their eggs, find or dig out holes in sheltered places, and
line them with silk. Species that live under stones or on plants, all line their customary
hiding-places with web to which they hold when at rest. Several of the large running
spiders dig holes in sand, and line them with web, so that the sand cannot fall in; and
build around the mouth a ring of
sticks and straws held together by
threads.

Some spiders make a great, irregu-
lar nest constructed of grass and
leaves drawn together with silken
threads. Fig. 22 represents a nest
of this kind made by a Dolomedes -
it is four or five inches in diameter
and contains the egg-cocoon. The
young hatch and ramble about in
this nest for some time ; the parent
spider remains near, usually holding
on under the nest, as represented in
the illustration.

6.—CoBWEBs.

The simple nests and tubes that have been already mentioned are, for the most part,
made by spiders which spin no other webs. The larger and better known cobwebs for
catching insects are made by comparatively few species. On damp mornings in summer
the grass-fields are seen to be half covered with flat webs, from an inch or two to a foot
in diameter, which are considered by the weatherwise as signs of a fair day. These
webs remain on the grass all the time, but only become visible from a distance when the
dew settles on them. Fig. 23 isa diagram of one of these nests, supposed, for convenience,
to be spun between pegs instead of grass. The flat part consists of strong threads from
peg to peg, crossed by finer ones, which the spider spins with the long hind-spinnerets,
swinging them from side to side and laying down a band of threads at each stroke. At
one side of the net is a tube leading down among the grass-stems. At the top the spider
usually stands just out of sight, and waits for something to light on the web, when she
runs out and snatches it, and carries it into the tube to eat. If anything too large walks
through the web, she turns round and retreats out of the lower end of the tube, and can
seldom be found afterwards. In favourable places these webs remain through the whole
season, and are enlarged, as the spider grows, by additions on the outer edges, and are
supported by threads running up into the neighbouring plants. [

Similar webs are made by several house-spiders, the mode of construction of which
is thus described by Kirby and Spence :—

“The weaving spider which is found in houses, having selected some corner for the
site of her web, and determined its extent, presses her spinners against one of the walls,
and thus glues to it one end of her thread. She then walks along the wall to the opposite
side, and there in hike manner fastens the other end. This thread, which is to form the
outer margin or selvage of her web, and requires strength, she triples or quadruples by a
repetition of the operation just described ; and from it she draws other threads in various
directions, the interstices of which she fills up by running from one to the other, and con-
necting them by new threads until the whole has assumed the gauze-like texture which
we see.

‘a

“'Il'he webs just described present merely a simple horizontal surface, but others
more frequently seen in out-houses and amongst bushes possess a very artificial appen-
dage. Besides the main web, the spider carries up from its edges and surface a number
of single threads, often to the height of many feet, joining and crossing each other in
various directions. Across these lines, which may be compared to the tackling of a ship,
flies seem unable to avoid directing their flight. The certain consequence is, that in
striking against these ropes they become slightly entangled, and, in their endeavours to
disengage themselves, rarely escape being precipitated into the net spread underneath for
their reception, where their doom is inevitable.

‘But the net is still incomplete. It is necessary that our hunter should conceal her
grim visage from the game for which she lies in wait. She does not, therefore, station
herself upon the surface of her net, but in a small silken apartment constructed below it,
aud completely hidden from view. ‘In this corner,’ to use the quaint translation of Pliny
by Philemon Holland, ‘ with what subtiltie does she retire, making semblance as though she
meant nothing less than that she doth, and as if she went about some other business! nay,
how close lieth she, that it is impossible to see whether any one be within or no!’ But
thus removed to a distance from her net and entirely out of sight of it, how is she to
know when her prey is entrapped? For this difficulty our ingenious weaver has pro-
vided. She has taken care to spin several threads from the edge of the net to that of her
hole, which at once inform her by their vibrations of the capture of a fly, and serve as a
bridge on which in an instant she can run to secure it.”

These webs, if let alone, are repeatedly enlarged till they are a foot or two wide, and
remain till they collect dust enough to tear them down by its weight.

Many spiders that make cobwebs live under them, back downwards, and many are so
formed that they can hardly walk right side up. The webs of Theridion (Fig. 18),
usually have at some part a tent or thicker portion under which the spider stands, and
from this run irregularly simple threads, crossing each other in all directions and held in
place by threads above and below. Such loosely constructed webs are often made in
houses, in corners of rooms, under furniture and in cellars. The same spider occasionally
spins out of doors on fences, but never on plants. When it has caught an insect and tied
it up, it gradually hoists it up into its nest, sometimes a considerable distance.

7.—GEOMETRICAL WEBS.

These familiar structures are the work of the family Hpeiride (Figs. 7 and 10).
The process of making them can be observed in any garden ; it is, of course, very different
from that described above in the construction of cobwebs. The net is usually fixed in a
perpendicular or somewhat oblique direction, in an opening between the leaves or branches
of some shrub or plant, in a window-frame or fence, or some such open wooden structure,
where there is a hole or crack in which they can hide when necessary.

“‘ Tt is obvious,” to quote Kirby and Spence’s description, ‘that round the whole extent
of the net, lines will be required to which can be attached those ends of the radii that are
furthest from the centre. Accordingly the construction of these exterior lines is the
spider’s first operation. She is careless about the shape of the area which they enclose,
but is guided by the distance or proximity of the points to which she can attach them.
She spares no pains, however, to strengthen and keep them in a proper degree of tension.
With the former view she pompores ne line of five or six or even more threads glued.
together ; and with the latter she fixes to them from different points a numerous and
intricate apparatus of smaller threads. Having thus completed the foundations of her
snare, she proceeds to fill up the outline. Attaching a thread to one of the main lines,
she walks along it, guiding it with one of her hind feet that it may not touch in any part
and be prematurely ¢ glued, and crosses over to the opposite side, where, by applying her
spinners, she firmly fixes it. To the middle of this diagonal thread, machi is to form the
centre of her net, she fixes a second, which in like manner she conveys and fastens to
another part of the lines encircling the area. Her work now proceeds rapidly. During
the preliminary operations she sometimes rests, as though her plan required meditation.
But no sooner are the marginal lines of her net firmly stretched, and two or three radii
spun from its centre, than she continues her labour so quickly and unremittingly that the
eye can scarcely follow her progress. The radii, to the number of about twenty, giving
the net the appearance of a wheel, are speedily finished. She then proceeds to the centre,
quickly turns herself round, and pulls each thread with her feet to ascertain its strength,
breaking any one that seems defective and replacing it by another. Next, she glues im-
mediately round the centre five or six small concentric circles, distant about half a line
from each other, and then four or five larger ones, each separated by a space of half an
inch or more. These last serve as a sort of temporary scaffolding to walk over, and to.
keep the radii properly stretched while she glues to them the concentric circles that are
to remain, which she now proceeds to construct. Placing herself at the circumference, and
fastening her thread to the end of one of the radii, she walks up that one, towards the
centre, to such a distance as to draw the thread from her body of a sufficient length to
reach to the next ; then stepping across, and conducting the thread with one of her hind
feet, she glues it with her spinners to the point in the adjoining radius to which it is to be
fixed. This process she repeats until she has filled up nearly the whole space from the
circumference to the centre with concentric circles, distant, from each other about two
lines. She always, however leaves a vacant interval around the smallest first spun circles
that are nearest to the centre. Lastly, she runs to the centre and bites away the small
cotton-like tuft that united all the radii, which being now held together by the circular
threads, have thus probably their elasticity increased ; and in the circular opening result-
ing from this procedure, she takes her station and watches for her prey.”

Some species, however, do not entirely surround the radii of their nets with
concentric circles, but leave one radius free, which serves as a sort of ladder for access to
the net. Others, again, spin spiral lines from the centre to the circumference, as shewn
in Fig. 24. In this case, when the radii are finished, the spider begins at the centre to
spin a spiral line across them, a, a, a, in Fig. 24; the turns of the spiral being as far
apart as the spider can conveniently reach. She climbs from one radius to the next,
holding her thread carefully off with one of the hind-feet till she gets to the right point,
and then turns up her abdomen and touches the radius with her spinnerets, thus fasten-
ing the cross-threads to it. The figure shows her in this position. When this spiral
has been carried to the outside of the web, she begins there another and closer one
of thread of a different kind. While the first thread was smooth, the latter is

58

Fey

j

my covered with a sticky liquid which
Wy soon collects on it in drops, and
makes it adhere to anything that
) touches it. After going round a few
times this spiral would come in con-
tact with that first spun, but as the
spider comes to the first she bites
it away. By beginning thus at the
outside, the spider is able to cover
the whole web with adhesive threads,
and, without stepping on it, take her
usual place inthe centre. She usually
is careful enough to spin beforehand
a thread from the centre to her nest,
and sometimes stays there, with one
foot on the thread, so as to feel if
anything is caught in the web. When
she feels a shake, she runs down to
the centre, feels the rays to see where
the insect is, and runs out, and seizes
it, or ties it up as already described.
We have described the web as con-
sisting of one regular spiral; but this
is seldom the case. It is usually

Fig. 24. wider on one side than the other, or
below than above, as in Fig. 24, where outside the spirals are several loops going partly
round the web. The web of Zilla consists entirely of such loops going three-quarters
round the web, and returning, leaving asegment without any cross-threads, in which is
the line from the centre to the spider’s nest. Most of the Lpeiride are brightly coloured,
and make no attempt at concealment when in the web. Others have odd shapes and
colours, and hang in the web in such positions that they look like anything but ani-
mals. Some species draw up their legs against their triangular abdomens, and ‘look like
bits of bark fallen into the web. Others are long and slender, and when at rest, either
in the web or out, lay their legs close together before and behind their bodies, so as to
look like straws. Others have oddly shaped abdomens under which the rest of the body
is concealed.

As the spider stands in her web, and feels a slight shake, such as would be caused
by a sudden wind, she draws her legs together, pulling the rays tighter, and so making
the whole web steady. If, however, the spider is frightened, and has no time to escape,
she throws her body back and forth as a man does in a swing, and thus shakes the web
so rapidly, that the spider can hardly be seen. The most usual habit, when alarmed, is
to drop to the ground, and lie there as if dead. /

8.—FLyYING SPIDERS.

Every-one has, no doubt, observed in summer and autumn long threads with one
end attached to the bushes, and the other blowing out in the wind; or bits of cob-web
(often termed “‘ gossamer”) carried along by the currents of air, with occasionally a little
spider attached to them. To account for these, various fanciful theories have been in-
vented. The old and very absurd notion was that gossamer was made of dew scorched
by the sun! Others imagined that spiders were able to force the thread from their
spinnerets, like water from a syringe, in any direction they chose.

If a spider be put on a stick surrounded by water, she manages in course of time to
escape by means of a thread carried across to some object beyond. ‘To find out how this
was done, Mr. Blackwall tried some experiments. He put spiders on sticks in vessels of
water, and they ran up and down, unable to escape as long as the air in the room was
still. But, if a draught of air passed the spider, she turned her head toward it, and

59

opened her spinnerets in the opposite direction. If the draught continued, a thread was
drawn out by it, which at length caught upon something, when the spider drew it tight
and escaped on it. If the air was kept still, or the spider covered with a glass, she
remained on the stick till taken off.

These experiments have been repeated, and show that
the spider does not shoot or throw the web in any way,
but takes advantage of currents of air, and allows threads
to be blown out to a considerable distance.

There is a still more curious use of this method of spin-
ning threads ; that is, in flying. Small spiders, especially on
fine days in the autumn, get up on the tops of bushes and
fences, each apparently anxious to get as high as possible,
and there raise themselves up on tiptoe, and turn their bodies
up, as in Fig 25, with their heads toward the wind, and spin-
nerets open. ‘A thread soon blows out from the spinnerets,
and, if the current of air continues, spins out to a length of
two or three yards, and then offers enough resistance to the
wind to carry the spider away with it up into the air. As
soon as she is clear, the spider turns around, and grasps the
thread with her feet, and seems to be very comfortable and
contented till she strikes against something. Sometimes
they rise rapidly, and are soon out of sight ; at other times
they blow along just above the ground.

This habit is not confined to any particular kinds of spiders, but is practised by
many small species of Hrigone, and by the young of many spiders of all families, that
when adult would be too large for it. The majority of spiders that fly in autumn are the
young of several species of Zycosa, that seem to spend the greater part of October in trying
to get as far above ground as possible. The best places to watch for them are garden-
fences, where they often swarm, and can be seen more distinctly than on bushes. |

Tt is still unexplained how the thread
starts from the spinnerets. It has been
often asserted that the spider fastens the
thread by the end, and allows a loop to blow
out in the wind; but in most cases, this is
certainly not done, only one thread being
visible. Sometimes, while a thread is blown
from the hinder spinnerets, another from
the front spinnerets is kept fast to the
ground (fig. 26); so that when the spider
blows away, it draws out a thread behind it
entirely independent of the one from which
it hangs. Sometimes, instead of a single ~
thread, several are blown out at once, like a long brush.

9.— WaTER SPIDERS.

One of the most curious and interesting of the spider family is the Argyroneta aquatica,
or Water-spider, which lives for the greater part of its life beneath the surface of water.
Kirby and Spence give the following description of its habitation :—

“Tt is built in the midst of water, and formed, in fact, of air! Spiders are usually
terrestrial, but this is aquatic, or rather amphibious ; for though she resides in the midst
of water, in which she swims with great celerity, sometimes on her belly, but more fre-
quently on her back, and is an admirable diver, she not unfrequently hunts on shore, and
having caught her prey, plunges with it to the bottom of the water. Here it is she forms
her singular and unique abode. She would evidently have but a very uncomfortable time
were she constantly wet, but this she is sagacious enough to avoid ; and by availing her-
self of some well-known philosophical principles, she constructs for herself an apartment in

60

which, like the mermaids and sea-nymphs of fable, she resides in comfort and security.
The following is her process. First she spins loose threads in various directions attached
to the leaves of aquatic plants, which may be called the frame-work of her chamber, and
over them she spreads a transparent varnish resembling liquid glass, which issues from the
middle of her spinners, and which is so elastic that it is capable of great expansion and
contraction ; and if a hole be made in it, it immediately closes again.”

The next operation—that of filling the nest with air—is thus described by Mr. Bell
(Journal of the Linnean Society): ‘ After the nest has been made as large as half an
acorn, she goes to the surface, and returns (in the instance observed, as many as fourteen
times successively), and each time brings down a bubble of air which she lets escape into
her nest. The bubble is held by the spinnerets and two hind-feet, which are crossed over
them, and is obtained in the following manner :—The spider climbs up on threads or plants
nearly to the surface, and puts an end of the abdomen out of water for an instant, and then
jerks it under, at the same time crossing the hind legs quickly over it. She then walks
down the plants to her nest, opens her hind-feet, and lets the bubble go.”

To go on with Kirby and Spence’s account :—‘‘ In about a quarter of an hour she has
transported as much air as suffices to expand her apartment to its intended extent, and
now finds herself in possession of a little aérial edifice, I had almost said an enchanted
palace, affording her a commodious and dry retreat in the very midst of the water. Here she
reposes unmoved by the storms that agitate the surface of the pool, and devours her prey
at ease and in safety. Both sexes form these lodgings. Ata particular season of the year
the male quits his apartment, approaches that of the female, enters it, and enlarging it by
the bubble of air that he carries with him, it becomes a common abode for the happy pair.
The spider which forms these singular habitations is one of the largest European species,
and in some countries is not uncommon in stagnant pools.”

The water-spiders run about on aquatic plants and catch the insects which live among
them. They lay their eggs in the nest, and the young come out and spin little nests of
their own, as soon as they are big enough. The hairs, with which their bodies are covered,
keep the skin from becoming wet as they go through the water ; and in the nest, which is
like a diving-bell, they are as dry as if it were under a stone, or in a hole on dry land.

The Rev. J. G. Wood states that the water-spider “is a tolerably common species in
England, being especially fond of inhabiting quiet and rather deep ditches, when it is well
sheltered, and the stream is not rapid enough to endanger the security of its domicile. It
is necessary that the water-plants to which the nest is fixed should be sufficiently firm to
prevent the nest from being swayed to one side, as, in that case, the air would escape,
and the water make its entrance. Owing to the vast number of these spiders that have
been sent to the London markets—where they are sold to those who possess fresh-water
aquaria—the species is not now nearly so plentiful as used to be the case, and, indeed, it
has been almost extirpated from several localities where it was formerly seen in great
numbers.”

10.—Trap-Door SPIDERS.

Comparatively little was known about these very curious spiders until the publica-
tion of Mr. Moggridge’s very interesting work, in which he records with great minuteness
the observations he made in the south of France.

The following illustration, Fig. 27, represents the principal kinds of nests that
these spiders construct. The most northern genus of this family, dtypus, makes a strong
silken tube, part of which forms the lining of a hole in the ground, and part lies above the
surface, among stones and plants, Fig. 27, A. The mouth of the tube is almost always
closed, at least when the spider is full-grown.

Another genus, which lives in warm countries, makes tubes lined with silk and closed
at the top bya trap-door. A common species in California, Cteniza Californica, is
brought thence by travellers. It digs its hole in a fine soil that becomes, when dry,
nearly as hard as a brick ; but the spider probably works when the ground is wet. The
holes are sometimes nearly an inch in diameter, and vary in depth from two or three
inches toa foot. The mouth isa little enlarged and closed by a thick cover that fits

61

tightly into it, like a cork intoa bottle. The cover is made of earth fastened together with
threads, and is lined, like the tube, with silk, and fastened by a thick hinge of silk at one
side, Fig. 27, B. "When the cover is closed it looks exactly like the ground about it.
‘The spider, when alarmed, holds on the inside of the door with its mandibles, and the two
front pairs of feet ; while the third and fourth pairs of legs are pressed out against the
walls of the tube, and hold the spider down so firmly that it is impossible to raise the
cover without tearing it.

Fig. 27.

‘Trap-door nests: A, nest of Atypus; B, nest with thick door; C, nest with thin door; D, branched nest ;
E, nest with two doors; F, branched nest with two doors ; ; G, nest with two branches.

One of the European species, described by Moggridge, makes a thin lid to its tube,
and lets it rest on the top of the tube, Fig. 27, C, covering it with leaves, moss, or
whatever happens to be near at hand, so that it is not easily distinguished.

A second species differs by constructing two or three inches down the tube another
door, Fig. 27, E, hanging to one side of the tube when not in use; but, when one tries to
dig the spider out from above, she pushes up the lower door, so that it looks as if it were
the bottom of an empty tube.

Another species digs a branch obliquely upward from the middle of the tube, closed
at the junction by a hanging-door, which, when pushed upward, can also be used to close
the main tube, Fig. 27, F. What use the spider makes of sucha complicated nest, nobody
knows from observation ; but Mr. Moggridge supposes that when an enemy, a parasitic
fly, for instance, comes into the mouth of the tube, the spider stops up the passage by
pressing up against the lower door ; but, if this is not enough, it dodges into the branch,
draws the door to behind it, and leaves the intruder to amuse himself in the empty tube.
The branch is sometimes carried up to the surface, where it is closed only by a few threads ;
so that, in case of siege, the spider could escape, and leave the whole nest to the enemy.

In these nests the spiders live most of the time, coming out at night, and some species
in the daytime, to catch insects, which they carry into the tube and eat. The eggs are
laid in the tube, and the young are hatched and live there till they are able to go alone,
when they go out and dig little holes for themselves. As the spider grows larger the
hole is made wider, and the cover enlarged by adding a layer of earth and silk: so that
another cover is made up of a number of layers, one over the other, on top of the original
little cover.

Moggridge relates (page 118) how a Nemesia Meridionalis constructed a trap- door i in
captivity, “after he had placed it on a flower-pot full of earth, in which he had made a
cylindrical hole. “She quickly disappeared into this hole, and dur ing the night following
she made a thin web over the aperture, into which she wove any materials that came to
hand. The trap-door at this stage resembled a rudely constructed, horizontal, geometrical
web, attached by two or three threads to the earth at the mouth of the hole, while in this
web were caught the bits of earth, roots, moss, leaves, etc., which the spider had thrown

62

into it from above. After the second night the door appeared nearly of the normal
texture and thickness, but in no case would it open completely, and it seemed that the
spider was too much disgusted with her quarters to think it worth while to make a
perfect door.”

These spiders are accustomed to put on their door moss like that which grows around
it, so as the more effectually to conceal it from observation. In one case where Mogegridge
had cut out a little clod of mossy earth about two inches thick and three square on the
surface, containing the top of the tube and the moss-covered cork-like door of a Nemesia,
he found on revisiting the place, six days later, that a new door had been made, and that
the spider had mor nted up to fetch moss from ‘the undisturbed bank above, planting it in
the earth which formed the crown of the door. Here the moss actually called the eye to
the trap which lay in a little plain of brown earth made by his digging.

The food of the European trap-door spiders consists largely of ants and other wing-
less insects, and they have been known to eat earth-worms and caterpillars. Mr. Moge-
ridge has Gian seen them, even in the daytime, open their doors a little, and anntelle Be
passing insects, sometimes taking hold of one too large to draw into the tube. One time he
and some friends marked some holes, and went and watched them in the night. The doors
were slightly open, and some of the ‘spiders’ legs thrust out over the rim of the hole. He
held a beetle near one of the spiders ; and she yeached the front part of her body out of
the tube, pushing the door wide open, seized the beetle, and backed quickly into the tube
again, the door closing by its own weight. Shortly after, she opened it again, and put
the beetle out alive and unhurt, probably because it was too hard to eat. He next drove
a sow-bug near another hole ; and the spider came out and snatched it in the same way,
and kept. it. None of the spiders came entirely out of their holes, and they were only a
little more active than in the daytime.

11.—GrowrH oF SPIDERS—THEIR Eacs AND Cocoons.

Persons unfamiliar with spiders find it hard to tell young from old, and male
from female. This is caused, in part, by the great differences between different
ages and sexes of the same spider, on account of which they are supposed to belong
to distinct species.

The adult males and females are only distinguished from each other, and from the
young, by the complete development of organs peculiar to each sex.

The males are usually smaller than the females, and have, in proportion to iets size,
smaller abdomens and longer legs. They are usually darker coloured, especially on the
head and front part of the body ; and markings which are distinct in the female run
together and become darker in the male. In most species these differences are not great ;
but in some no one would ever suppose, without other evidence, that the males and
females had any relationship to each other. The most extreme cases of this kind are
Argiope and Nephila, where the male is about a tenth as large as the female.

The female of one of the common crab spiders is white as milk, with a crimson
stripe on each side of the abdomen ; while the male is a little brown-and-yellow spider,
with dark markings of a pattern common in the family to which it belongs.

When the female is prepared to lay her eggs, she makes a little web and drops them
upon it ; then she covers them over with silk, forming a cocoon, in which the young re-
main till some time after they are hatched. The laying of the eggs is seldom seen, for
the spider does it at night and in retired places, and often in captivity refuses to lay at all.

Many spiders make their cocoons against a flat surface, where they remain attached
by one side. Attus mystaceus spins, before laying, a thick nest of white silk on the under
side of a stone. In this she thickens a circular patch: on the upper side, next the stone,
and discharges her eggs upward against it. They adhere and are covered with white silk.

Epeira strix spins, before laying, a bunch of loose silk ; she touches her spinnerets, draws
them away ashort distance, at the same time pressing upward with the hind feet ; then she
moves the abdomen a little sideways, and attaches the band of threads so as to form a loop.
She keeps making these loops, turning round, at the same time, so as to form a

rounded bunch of them, into the
middle of which she afterwards lays
the eggs, as in Fig. 28. The eggs,
which are like a drop of jelly, are
held up by the loose threads till the
spider has time to spin under them a
covering of stronger silk. Zpeira
vulgaris makes a similar cocoon up-
ward, downward, or sidewise, as may
be most convenient,

Most of the Theridiide make cocoons of loose silk, held up in the
webb by numerous threads. Some hang the cocoon by a stem, Fig. 29.

The large species of Argiope makes a big pear-shaped cocoon
hanging in grass or bushes, Fig. 30. A stem of loose brown silk is
first made, and under this the eggs attached (at any rate this had been
done in onewhich had been abandoned unfinished) ; then
a cup-shaped piece is made under the eggs; the bunch
of loose silk is spun over all, and finally the paper-like shell.

These cocoons are made late in the summer and the young

stay in them till the next season. Many cocoons of irreg- ,
ular shape may be found in cellars and other retired places
during the winter ; the eggs contained in them are hatched
’ in the following spring.
ae The hatching occupies a day or two. First the shell, or
Fig. 29 rather the skin, cracks along the lines between the legs, and
comes off in rags; then the creature slowly stretches itself and creeps out. It is now
pale and soft, without any hairs or spines and only small claws on its feet ; but in a few
days it gets rid of another skin and begins to look like a spider. The eyes become darker
coloured, marks on the thorax become more distinct, and a dark stripe appears across the
edge of each segment of the abdomen; the hairs are long and few in number. Before the
next month, the brood usually leaves the cocoon and for a time they live together in a
web spun in common. As the spider grows large it has to moult from time to time ; as
many as nine moults have been observed in a species of Zegenaria that lives for several
years. er
Many species, and among them some of the largest, live only. one year, hatching in
the winter, leaving the cocoon in early summer and laying eggs and dying in autumn.
Other species seem to require two years for their growth ; hatching in summer, passing
their first winter half grown, growing up the next summer, but laying no eggs till the
second spring. Some species are found adult at all seasons, and may live several years.
After spiders have passed their second moult, they usually live in the same places, and
follow the same habits, as the adults. ‘

Several house spiders have probably been imported, like rats, and are found all over
the world ; while other very common species never spread beyond the countries where
they are most abundant.

THE PEA WEEVIL (Bruchus Pisi).
By W. Saunpers, Lonpon.

The pea weevil, or pea bug as it is more commonly called, has become a very serious
evil in Ontario, and prevails at present to such an extent as to entail enormous losses on
the farming community, since peas are cultivated over a greater or lesser area on almost
every farm. This insect, which is believed to bea native of America, was first noticed in
Pennsylvania, attacking the pea early in the present century, and from thence has gradu-
ally spread over the whole of the Northern Uuited States and Canada; it has also been
carried to Europe where it has firmly established itself in the southern portions, and in

64

England, although it is not nearly so abundant and destructive in Europe as it is
with us.

This beetle, Fig. 31, a, is a little more than one-tenth of an inch long, of a rusty,
blackish colour with a whitish spot on the hinder part of the
the thorax, and several of the same colour on each wing case
behind the middle ; also a white spot shaped somewhat like
the letter T on the tip of the body. In the cut, the in-
sect is much magnified ; the small outline figure at the side
_ shews the natural size.

' As soon as peas are in bloom the pea weevils are on the
wing, and when the young pods are formed the females de-
, posit their eggs on the surface, fastening them with a glutin-
" ous fluid, secreted from their bodies. These eggs are very ~
small, much longer than wide, pointed in front and blunt
behind, and of a yellow colour. The young larva, which is
hatched in a few days, is of a deep yellow colour with a
black head. It eats its way at once through the tender pod,

Fig. 31. and directly into the first pea it meets with, the wounded
portion closing up in the growing pod, and leaving but a mere speck in the pea to mark the
place of entrance. The larva feeds on the growing pea and consumes its substance, usually
avoiding any injury to the germ, so that infested peas will generally germinate as readily as
those which are free from the bug. The soft, whitish fleshy grub, Fig. 31, 6, when full
grown, eats a circular hole on one side of the pea, not quite through to the surface, but
leaves the thin skin unbroken. It then changes to a chrysalis, and finally toa beetle
within the pea, and when the beetle is ready to escape it has only to eat its way through —
the thin skin which the larva had left covering the hole.

Few persons are aware how many insects they unconsciously devour while indulging
in the luxury of early green peas. In this instance, as in many others, ‘ Where ignorance
is bliss, “tis folly to be wise.” Some console themselves with the idea that the fat little
creatures having fed on nothing but green peas, are only green peas in a modified form,
and besides this they are cooked. A very small discoloured spot on the pea indicates the
presence of an occupant, and if the pea be opened at this point the whitish footless grub
will be found within.

Sometimes, especially during an unusually warm season, many of the weevils will
escape from the peas in the fall, but usually they remain in them during the greater
part of the winter, and many do not issue until after the peas are sown as seed in the
ground. Hence we see how easily this pest may be introduced into a district hitherto
free from it, by sowing infested peas. All seed peas should be carefully examined, and as
the insects diminish the weight of the peas in which they lodge nearly one half, an expe-
ditious and moderately safe way of separating the sound from the unsound peas is to throw
them into water when most of the good peas will sink while the infested ones will float

A very effectual remedy, and one which would be very successful were it generally
adopted, is to keep seed peas in tight vessels in a dry place over one year before planting
them, during which time, if any of them contain bugs, these will escape and perish with-
out having opportunity to propagate.

It has also been recommended to scald the peas about to be sown by dipping them
for 2 moment or two in hot water before planting, by which means the weevils are killed
and the sprouting of the peas quickened.

As the duration of this insect in the beetle state is limited, peas sown late are much
more likely to escape injury than those planted early. Harris, in his ‘ Insects Injurious
to Vegetation,” mentions an instance of a gentleman who sowed his peas on the 10th of
June for six years in succession, and never found an insect in them during that period.

A very effectual method of getting rid of this pest from any section of country
would be for the farmers to mutually agree to sow no peas for one year. At a
recent meeting of the County Council in London, Mr. Henry Anderson, of Westminster,
presented a memorial to that body, setting forth the importance of this subject, and ask-
ing the Council to petition the Legislature to pass an Act giving County Councils the

3

65

power to prohibit entirely the growing of peas in any one section for a season. Such a
course faithfully carried out and followed by a careful selection of seed the next season,
would doubtless almost, if not entirely, eradicate the pest from such district for a time,
and thus effect a large saving to the community; hence it is most desirable in the interest
of our farmers that some such permissive restrictive measure be enacted. Unfortunately,
in this instance, either from want of proper information on the subject, or perhaps under-
rating its importance, the Council declined to take action in the matter.

SCARABAIDAX—DIGGERS.
By James FLETCHER, OTTAWA, ONT.

The members of the family of beetles, which bear the above name, have been objects
of peculiar interest to mankind for thousands of years. This is chiefly owing to the fact
that the typical species of the family to which it belongs, played such an important part
in the religion of the ancient Egyptians, and also on account of those very habits which
gave rise to the devotion and adoration lavished upon it by that remarkable people.

These beetles belong to a division of the insect world to which Latreille gave the
name of Lamellicornes or leaf-horned, which corresponds with the Linnean genera Lu-
canus and Scarabeus, and are easily distinguished by having the antenne, which are gen-
erally short and nine or ten jointed, terminated by a large club-shaped organ, composed
of, as a rule, three of the apical joints, which are formed into a series of flat plates, and
open like the rays of a fan or the leaves of a book, or of which the basal joint of the club
is hollowed so as to form a kind of cup receiving the subsequent joints ; in others the
terminal joints form a kind of comb. The form of these insects is robust and heavy, and
the males are often to be known at first sight by the presence of singular horns on the
head and thorax, and by the great size of the mandibles. So different an aspect is given
to the males by these organs that, in some instances, it seems almost incredible that they
can belong to the same species as the females, and it has frequently happened that the two
sexes have been recorded as two different species.

This division is one of very great extent, and embraces within its wide, but clearly
defined limits, insects of the most various characters. It comprises the largest and hand-
somest of the beetle race, and at the same time some individuals very small and sombre in
appearance. Strangely enough, too, it includes within its ranks some of the most bene-
ficial and some of the most destructive of all insects ; hence, as well as from the immense
number of species, and the consequently important rd/e they must perform in the economy
of nature, they were placed by Linneus and Fabricius at the head of the Coleoptera, or
sheath-winged insects (koAeos—a sheath, and rrepa—wings.) This arrangement, however,
has not been adhered to by later authorities, and they are now placed immediately before
the Buprestide. ;

The majority of these insects, and especially the gigantic species, to be mentioned
later, are inhabitants of the tropics.

The two Linnean genera, above named Lucanus and Scarabeus, constitute the two
primary groups into which the Lamellicornes are divisible, and to which Dumeril gave
the sectional names

Priocera (Lucanus), club of antenne serrated.

Petalocera (Scarabeus), club of antennz lamellated.

The first of these or the family Lucanipm, Leach, corresponds to the Linnean
genus Lucanus, and is distinguished by having the antenne abruptly bent into an angle
about the centre, generally composed of ten joints, and terminated by a pectinated, fissile,
or sub-serrated club. A striking characteristic, too, of this family is the exserted and un-
usually developed mandibles of the males, which gives them a most ferocious aspect, and
from which the popular names of stag-beetles, horn-bugs and flying-bulls have originated.
These organs in some instances (e.g., Chiosognathus Grantii of Chili), equal the entire
length of the body. They are capable of biting with great force, and the females, not-
withstanding that they are furnished with very small mandibles in comparison to their

5

66

larger mates, are considerably the more formidable of the two, their short, thick, sharp-
pointed mandibles, being provided for the purpose of boring holes in bark to deposit their
eggs, are very strong.

This family is represented in Ontario by a small number of
insects, the most typical of which is Lucanus dama, Thunb. (Fig.
32), which is a large, smooth, brown beetle, of little more than

'- aninchin length. The jaws of the male are very long, and finely
pointed and are curved like a sickle and bear on their inner
edge, near the middle, a small sharp tooth. The head, to bear
these large mandibles, is necessarily large ; in the female it is
much smaller and narrower, and is densely covered with punc-
tures which give it a rough appearance. The eggs, which are
yellow and oval, are laid in a hole, made by the female, in the
bark of a tree, near the root, about the end of July, when this
beetle should be sought for. The grubs live in the trunks and
roots of several sorts of trees, but chiefly in old apple trees, willows
and oaks ; they are long, thick, nearly cylindric white grubs, of

Fig. 32. a very fleshy consistency, closely resembling, in general appearance,
the larve of the Scarabeide, but they are distinctly separated by certain characteristic
points in their internal structure, and by their bodies being destitute of the transverse fold-
ings so conspicuous in the latter. The larvee of the Lamellicornes are remarkable for having
their bodies curved, so that the end of the abdomen is drawn under the body, which pre-
vents them from crawling on a flat surface and necessitates their always lying on their sides.
The larva of Lucanus dama has a horny rust-coloured head furnished with two powerful
jaws, which it employs in gnawing the wood, upon which it feeds and which it reduces to a
kind of tan. Theantennzare short. It has six reddish articulated legs, which are attached
to the first three segments of the body. When mature it forms a cocoon out of the minute
chips and debris which it has itself made during its life. In this cocoon it undergoes its
transformation to the pupa and perfect insect. In the pupa state the large mandibles or
horns of the wale are folded down over the breast. Résel, who studied thoroughly the
European representative of this family (Lucanus cervus) and discovered that the male and
female were one species and not two, as previously believed, says that that insect lives six
years as a larva. The injury which they cause is sometimes considerable, as they bore
not only into the solid wood but also into the roots of trees.

It is supposed that the larve of these insects are what were eaten by the Romans, as
a great delicacy, under the name of Cossus.

The name of Pectinicornes or ‘‘comb-horned,” has been proposed for this family, but
so far it has not been generally accepted by entomologists.

The Petalocera of Dumeril (Scarabeus of Linnzus) or second division of Lamellicorn
insects, is one of immense extent, being divided into more than 700 genera, comprising
some 6000 species. They are distinguished from the foregoing family by having the
antenne not abruptly bent into an angle, eight, nine or ten jointed and terminated by
a large mass, composed of several, generally three, plates, which shut and open at will. In
some species these plates are flat, so as to be placed side by side, in others the basal one
is hollowed so as to forma sort of box in which the intermediate plate is enclosed. The
mandibles do not exhibit any striking sexual variations ; but the head and thorax of the
males in some of the groups, are armed with horns and protuberances of the most
bizarre and diversified appearance, of which it is very difficult to conceive the uses.
The antennez of the males too, are occasionally developed more than those of the females.
The mentum is large and horny. The body is generally more or less convex, the legs
robust and as a rule toothed on the outer edge.

These insects are almost all of them vegetable feeders, the greater part subsisting
upon it when in a state of decay. Some in the perfect state feed upon leaves and flowers,
and their /arve upon the roots of grass, etc., often causing great damage. In the colours
of these insects we find a conformity to their habits ; those that burrow under ground are
generally of black and obscure hues, while those that frequent leaves and flowers are often
splendidly attired. The origin of the name Scarabeus is doubtful ; the word never occurs

67

but in the writings of Latin authors ; yet Fabricius and Olivier give its derivation from
the Greek oxéztw—to dig, which MacLeay doubts, considering it to be of Etruscan origin,
adding that it may have been obtained from the Greek oxapupaopar—the verb duacKkapipyoar
being properly applied to the actions of animals which scratch or dig up the earth with
the claws. Pliny gave a description of the sacred beetle of the Egyptians under the
name Scarabeus ; and in later times Linnzeus applied it in a general way to the whole of
the Lamellicorn beetles, placing the gigantic horned species, at the head of the genus.
The Rev. J. G. Wood writes as follows :—‘‘ The Latin word Scarabeeus is nothing but a
corruption of the Greek word xapafos—a crab. It was also employed to designate the cuttle-
fish, on account of its mode of crawling, the name being composed of two Greek words,
signifying ‘to walk on the head.’” By Aristotle, it is applied to an insect which is evi-
dently the stag-beetle ; but Linnzeus was the first who gave it to the ground-beetle, and it
has been so universally employed that it will continue to hold its place.

It is possible that the name may have been applied to these beetles by Pliny, from
the fact that the female of the sacred Scarabzeus, when it is rolling the balls of dung, in
each of which it has deposited an egg, to the place where it has dug its burrow, does so
by walking backwards and pushing the ball before it. Now from the size of the ball,
generally over an inch-and-a-half in diameter, it actually has almost to stand on its head
when it places its feet on the top to roll it.

It would be impossible to do more, here, than mention briefly some of the most in-
teresting sub-families and species of this extensive family of insects, the members of which
exhibit such great variations in the form and arrangement of the various organs of the
body, although preserving a characteristic appearance, and conjoined with it the lamellate
antennal club and fossorial legs.

They have been conveniently divided into three divisions by De Geer.

1. Those which live upon or beneath the surface of the earth, or “ ground beetles.”

2. Those which in the perfect state are found upon and devour the leaves of trees, or
“ tree-beetles.”

3. Those which in the perfect state frequent flowers, or ‘“ flower-beetles.”

To the first group belong the most useful of insects, who in providing for the per-
petuation of their species, at the same time till and manure the soil and dispose of offen-
sive matter. This will be better understood by a glance at their life histories.

In Ontario we sometimes meet with a fine ground beetle, named Canthon laevis,
Drury, which belongs to the same sub-tribe (Atewchini) as the Egyptian Scarabeus, to
which it bears great resemblance. A noticeable feature of these insects is the length of
their hind-legs, and the proximity of the bases or cox to the end of the body. This
peculiar structure is of particular service to them. Their mode of depositing eggs is very
remarkable. The female having discovered a deposit of fresh cow-dung, at once seeks for
a suitable place, and digs out a pit about 18 inches deep ; she then returns and gathers
together exactly so much of the material as will amply supply one grub with food, and
in the centre of this she deposits an egg. She then proceeds to form it into a round ball ;
at first it is quite wet and soft, but by turning her back to it she works it backwards, in
the hot sun-shine, by means of her long hind-legs, over dusty or sandy soil, and it gradu-
ally becomes rounder and harder, by taking up some of the dry dust as it goes along.
When she arrives at the hole, she previously prepared, if her ball is dry and hard enough,
she drops it in and covers it up ; but if it is not sufficiently hard, she takes it for another
short circuit, during which it picks up more dry dust and gains the required consistency,
and then brings it back to the hole and buries it. If the day is wet or even cloudy,
these insects will not work at all. Occasionally intervening objects render this task of
transportation exceedingly ditficult ; but she works away with the utmost patience and de-
termination, and is generally successful ; sometimes as a last resource when obstacles of unus-
ual magnitude have to be surmounted, she will call in the aid of one or two other beetles. It
is curious, too, how cheerfully they seem to work for each other, and although it is almost
impossible to induce one of these insects to abandon the ball which contains her egg, yet
if when two females are engaged in depositing eggs at the same time, the balls are changed,
neither seems to be aware of the deception, and they labour as contentedly for each other’s
egg as if it were their own.

68

There are also several species of another sub-tribe (Coprinz), closely allied to the
Ateuchini, which possess somewhat similar habits. They differ chiefly by frequently
having the heads of the males armed with a large curved horn, and by having the middle
and hind tibize gradually thickened, which unfits them for transporting the balls of
material which serve for the food of the larve; though some of the species do construct
balls, they bury them in the place where they are formed. Notwithstanding that these
insects live in such unclean localities, they are remarkable for their constant state of
glossy cleanliness; this is due to an oily fluid which they secrete, and which prevents all the
nasty things they live amongst from collecting upon them or staining their coats.

The type of this group (Scarabeidz), is the renowned Ateuchus Sacer, or Sacred
Scarabeus, of the Egyptians, perhaps the most celebrated of insects. It was wor-
shipped by them as a god, and dried specimens of the actual beetles or models of all
sizes and in every possible material, from the commonest stone to the most precious metals,
have been frequently discovered in Sarcophagi, or rolled up in mummies and other ancient
relics found among the monuments on the borders of the Nile. For common use they
were made very small, and some were pierced so as to form necklaces for the women,
others were used as seals, as is shewn by the inscriptions beneath them. Plutarch states
that the military caste made use of the figure of a Scarabzeus as a seal, and Horappollon
explains this by asserting that this insect peculiarly represents man, since (as was formerly
believed) “there are no females of its species.” A male wishing to procreate, said the
Egyptians, takes some of the dung of an ox, and having fashioned it into the shape of
the world, rolls it with its hind legs from east to west, and places it in the ground, where
it remains twenty-eight days. On the twenty-ninth day the ball is exhumed and thrown
into the water, where it opens and another male comes forth. Some of the models of the
Scarabeeus which have been found are of very large dimensions—one in the British
Museum, carved in granite, is about four feet in length. There are several smaller
specimens cut from marble, porphyry, agate, lapis-lazuli, garnet and gold.

Representations of it are to be found everywhere throughout the whole land of Egypt,
carved upon the temples, tombs, monuments and obelisks.

The reverence shewn to these insects seems to have been called forth by many causes
in their imaginative minds. Being an agricultural people, and knowing the habits of the
Scarabeeus, they worshipped it, because they could appreciate how, by the manner in which
it provided for the welfare of its own offspring, it also benefited them by fertilizing the
ground, and removing from the surface obnoxious matter. Its sudden appearance in great
numbers on the sandy margins of the Nile, after the fall of the water every year, together
with its extraordinary motions whilst rolling along its globular balls of dung, were re-
garded as mystically representing the resurrection of the soul, and the motions of the earth
and sun. It, with the earthen ball containing an egg in the centre, was also regarded as
an emblem of fecundity, and to this day, the beetle is eaten by the women of Egypt. On
account of the shape of the egg-ball, and the wonderful care bestowed upon it by the
parent beetle, it was employed as an emblem of the Creator’s watchful care over the
world.

In addition to these, a short mention must be made of two other families of ground
beetles which are much commoner, and which from that account perform the useful work
of their kind much more fully than the above-named interesting species. These two fam-
ilies are the Geotrupide or earthdiggers, and the Aphodiide, or cow-dung frequenters.
They do not form balls of the food for their larvee, but burrow straight through the mass
and down into the earth below ; they then bring down some of the material from above,
and deposit an egg in it, in the same way as the others. Two well known instances of
these families are Geotrupes blackburnit, a small, blackish beetle with a green lustre, of
about one-half or three-quarters of an inch in length, and Aphodius jfimetarius, a small
cylindric-shaped insect, with coral-red elytra, which is always to be seen about manure
heaps in spring, and although it is one of the commonest of our insects, was only intro-
duced from Europe a comparatively small number of years ago.

To the second division of the Scarabeeide, namely, the “ Tree-beetles,” belong a large
number of insects, whicn are perhaps even more injurious than their near relatives, the
ground beetles, are beneficial. These are of much greater interest to the farmer than

69

any other class, and as several of them are of large size and very common, they annually
destroy an enormous amount of produce. The greatest amount of injury is done during
the larval state, which they spend in the ground consuming the fibrous roots of plants.
The most injurious of these beetles, on account of the great amount of damage they have
done, have already called forth very full descriptions in our annual reports, consequently,
it is not worth while again to take up space by describing them. Among the most promi-
nent are :

The May-bugs or Chafers, which were all included by Fabricius in the gcnus
Melolontha, a aan used by the ancient Greeks to distinguish the same kind of feecaie.
which were supposed by them, as the name implies, to be pr oduced from or with the
flowers of apple trees. They are, I have no hesitation in saying, the most injurious insects
in the world. The accompanying figure i
(33) g gives a faithful representation of these
insects in their different stages, and they
may be easily recognized from it; they are
already too well known, I fear, to farmers.
In fig. 33, No. 2 the larval stage, known as the
* White Worm,” which is the greatest depre-
dator, is also represented. It is a soft white
worm with six legs and a brownish head;
the body is very fat, and is about an inch
and a half long. It lives for several (as a
rule three) years in this stage, during which
time it destroys everything that comes within
its reach in the way of roots of plants. It
has been found to be very injurious to the
roots of strawberries, potatoes, corn and other
vegetables, but particularly so to grass. They
‘have been known to abound in such pro- Fig. 33
digious numbers that they ate all the roots of the grass ina pasture, and the plants could be
rolled up from the surface as if they had been cut off by a turf-cutter’s spade. The pupa
stage of this insect is also shewn. ‘The insect itself is scientifically known by the name
of Lachnosterna quercina, Knoch. <A full and most interesting account of this insect is to
be found in the Annual Report of 1872, and in the same report also will be found an

} article by Mr. Saunders treating of the “Rose-bug,” Macrodactylus subspinosus
Fab. (fig. 34), an insect also belonging to this division, which has proved very
destructive to grape vines in some localities.
There is another beetle which feeds entirely on the wild and cultivated vines,
but never occurs, I believe, in sufficient numbers to cause very material damage;
Fig, 34 this is the spotted vine beetle or Peli-
dnota punctata, Linn. It is a large handsome
beetle, of which Fig. 35 is a life-sized represen-
tation, the colour of the smooth elytra or wing
cases is reddish-brown and each of them is
decorated with three conspicuous black spots.
The thorax, which is of a deeper colour, also
bears two more rather smaller ones. The
jaws and scutellum are both black and its legs
and under surface are of a dark metallic green.
The Larva, Fig. 35, a, is a large fat grub much
like the white-worm but may be at once identi-
fied by a distinct heart-shaped swelling, Fig. d;
on the last segment ; the colour t00, is of a
purer white, and the skin is Jess wrinkled. It
has been found feeding upon the rotten stumps
and roots of pear trees. Towards the end of
the summer the larva forms a cocoon of chips

70

of wood and about a fortnight after, the perfect insect emerges, and may be found on
grape vines in Western Canada, during the months of July, August and September. To
this division belongs the beautiful Goldsmith Beetle, Cotalpa Lanigera, of which an inter-
esting account appeared in the February number of the Hntomologist, written by Mr.
Saunders. As many of the readers of the Annual Report do not read that periodical
I insert it.

“This is, without doubt, the most beautiful of our leaf-eating beetles. It is nearly an
inch in length (fig. 36), of a broad oval form with the wing cases of a rich yellow colour,
with a pale metallic lustre, while the top of the head and thorax gleams like burnished gold
of a brilliant reddish cast. The under surface has a polished coppery hue
and is thickly covered with whitish wool; this latter characteristic hay-
ing suggested its specific name lanigera (wool-bearer).

“This insect appears late in May, and during the month of June. It
is distributed over a very wide area, embracing most of the northern
United States and Canada, and although seldom very abundant, it is
rarely that a season passes without more or less of them being seen.
During the day, they are inactive, and may be found clinging to the under
side of the leaves of trees, often drawing together two or three leaves—
which they hold with their sharp claws—for the purpose of concealing

Fig. 36. themselves. At dusk they issue from their hiding places and fly about
with a buzzing sound among the branches of trees, the tender leaves of which they devour ;
the pear tree, the oak, poplar, hickory, silver abele and sweet gum all suffer more or less
from their attacks. Like the May bug, this beautiful creature is often attracted by light,
and flies into open windows on summer evenings, dashing in a bewildered sort of way against
everything it meets with to the great alarm of nervous inmates. In some seasons they
occur in considerable abundance, and may be readily captured by shaking the trees on
which they are lodged in the day-time, when they do not attempt to fly, but fall at once to
the ground.

“The beetle is short-lived. The female deposits her eggs in the ground during the
latter part of June, and having thus provided for the continuance of her species, dies. The
eggs are laid during the night singly and at different depths, the number probably not
exceeding twenty in all. They are very large for the size of the beetle, being nearly one-
tenth of an inch in length, of a long ovoid form and white tranluscent appearance.

“Tn less than a month the young larva is hatched ; it is of a dull white colour, with a
brown polished horny head, and the extremity of the abdomen lead colour. The mature
larva is a thick, whitish, fleshy grub, very similar in appearance to that of the common
May bug, familiarly known as ‘the white grub.’ It lives in the ground and feeds on
the roots of plants, and on this account it is sometimes very destructive to strawberry
patches.

“‘ Several years are required to bring this grub to maturity ; finally it reaches its full
growth in the fall, and changes to the perfect beetle early the following spring.” I have
never met with this insect nor the spotted vine beetle in this part of Ontario.

The last division, of ‘Flower Beetles,” is very poorly represented in Canada, and the
individuals rather small. They are, however, striking in appearance. They belong chiefly
to the genus Cetonia and its allies, and are easily distinguished from the other scarabeei-
ans by their lower jaws, which are generally soft on the inside and are provided with a
flat brush of hairs with which they collect the pollen and juices upon which they feed.

x Most of the brightly coloured kinds are diurnal, the dull ones nocturnal. Of
the Canadian diurnal flower beetles, the Euryomias are perhaps the most typ-
ical. This genus was separated from the Cetonias by Lacordaire on account
of the structure of the oral organs. We have twoin our fauna; #. da,
Lina (Fig. 37), a rare insect in this part of Canada ; but common enough in the
West and in the United States to occasionally do much damage to the peach
crop, by boring into the fruit just when it is ready for the market. The other
Fig. 37. species, Z. fulgida, Fab., is also common in Western Canada; I have taken it
in numbers near London, Ont., on the flowers of Vibwrnum pubescens, Pursh, in the month
of June.

ral

Of the nocturnal flower-beetles the two Osmodermas may be mentioned. These are
large insects, remarkable for giving out an odour like that of Russian leather. They
conceal themselves during the ‘day in crevices of bark and hollow trees, where they feed
upon the sap that flows from the bark. The name is derived from two Greek words—
“out, an odour, and d€pya, the skin. O. scabra, Beauy., or the rough Osmoderma is
rather the smaller of the two, and is about three-quarters of an inch long, with wide
roughly-granulated elytra, and a considerably narrower thorax. When resting with their
legs extended and almost straight, they have a very stilted, unlife-like appearance. The
colour is deep purplish-brown, with a bronze lustre. The larvee, which resemble those of the
May-bug, may be found in the decayed portions of living apple and cherry trees, where they
considerably quicken the work of destruction already begun. 0. eremicola, Knoch, or the
Hermit Osmoderma, is slightly larger and of a deep mahogany brown colour, perfectly
smooth and highly polished. The male may be known by the presence of a deep pit in the
middle of the thorax. In other respects it is like the last.

There is a very remarkable group of Cetonide, known by the name of Goliath
beetles, to which Linneus gave the name (‘oliathus, and placed them first in the whole of
his arrangement of coleoptera. As the name implies, they are of very large size, some
reaching the gigantic proportions of over four inches in length. What adds “to their size,
too, is that they are correspondingly broad.

A most interesting account of these beetles is to be found in the Rev. J. G. Wood’s
charming book, “ Insects Abroad.” He describes Goliathus Druryu, one of the largest
and most beautiful, as follows :—

“Its length is four inches and a quarter, and the breadth exactly two inches. The
head, which is furnished with two curious projections, is greyish-white, except the horns,
which are black and deeply-punctured ; the thorax is black, and upon it are drawn a num-
ber of creamy-white stripes ; the elytra are warm chocolate with a velvet-like surface, sur-
rounded with a belt of the same creamy-white as that upon the thorax—below, it is black
with a mixture of green; the tibie of the first pair of legs are much flattened and deeply
punctured; they are of a reddish hue. Those of the hind pair are furnished on the inner
side with a dense ridge of golden hairs witha silken gloss ; the tarsiare black. For many
years this was the rarest of insects, only one specimen was known, which was picked up
dead, floating in an African river. Of late years, however, several have been brought to
England from the west coast of Africa, and among others a magnificent specimen of a
cocoon containing the perfect insect. This is now in the British Museum, and is about
the size of a swan’s egg. It has very thin walls, but is: strengthened round the middle
exteriorly by a remarkable raised belt.

NOTES ON VARIOUS INSECTS.
By Wm. Saunprers, Lonpon.

In the following remarks, reference will be made to some insects which, on account
of their frequent appearance, or their curious or beautiful structure, are objects of interest
to every observer of nature, and also to insects to which the writer’s attention has been
specially called during the past year.

Dytiscus Harristi (fig. 38). This is one of the carnivorous water beetles, known as
“Diving Beetles” or ‘‘ Water Tigers,” a strong, sturdy creature of an oval flattened
form, with oar- -like swimming legs, covered with long hairs. It is very active in the
water, darting and diving about in different directions with great rapidity, the form
of its body with sharp ‘sides enabling it to cut through the water with great ease.
They may well be called the sharks of the. insect world, for there are few things that live in
the water which are safe from their attacks. They are especial enemies of the larve of
other aquatic insects ; they feed also upon tadpoles, molluscs and small fish, and when
pressed by hunger they do not hesitate to devour one another. They may be kept in
an aquarium and fed on water insects and small pieces of raw meat, which they suck
greedily.

72

\ / Fig. 38 represents this species very correctly ; it is black with a
\ broad margin of pale yellow on each side, and stripes of the same
Noein i ‘ colour across the front of the head and on both the front and hind

margins of the thorax ; there is also an irregular yellow line cross-
ing the wing covers near the tip. The under side is somewhat paler
with reddish markings. Examples of this insect are often brought
%\. to us during the summer by persons who have found them in tubs
‘i, or barrels of water and who were puzzled to know how they could
.\ get there. Beneath their hard wing covers they have a large pair
. of membranous wings, by the use of which they can fly with great
i} ease ; by this means they are enabled to travel from pond to pond
*in search of their prey. When wishing to change their location
they crawl out of the water (usually towards evening) either up
some reed or other water plant, or to the margin of the pond, and
suddenly open their wing covers, expand their wings and rise into
the air almost perpendicularly to a great height. Their descent is
nearly as sudden and direct, and they often, when descending, drop
into the water with considerakle force. It would appear that they

Fig. 38. are enabled to distinguish the water from a considerable height by
its glassy surface, for. sometimes they have been known to drop with violence upon
glazed garden sash, which they had evidently mistaken for water.

The female lays her eggs in the water, where they soon hatch into young larve, pos-
sessing the ferocious disposition and voracious appetite of their parents. The larve grow
rapidly, and when mature are about two inches long, with large flattened heads armed
with sickle-like jaws, with which they seize other insects and hold them while they suck
their juices ; they sometimes quickly snip off the tails of young tadpoles, and are known
to attack young fishes and suck their blood. Many years ago, when searching with a
dip-net in a pond for the larvee of Dragon-flies, we caught one of these savage creatures,
and supposing it could be as safely handled as the libellule larvee, took hold of it, when it
quickly turned and buried its sharp jaws in the flesh of one of our fingers, making the
blood flow quite freely. These larve breathe through their tails, which they protrude
into the air for that purpose, When full grown and about to assume the pupa state, the
larva leaves the water, and burying itself in the earth, constructs there a round cell with-
in which it undergoes its change, and if this occurs in summer, it appears in two or three
weeks as a perfect beetle ; but if in autumn it remains in the chrysalis state all winter,
transforming to a beetle in the spring.

Fig. 39 represents another of our large water beetles, Hydrophilus
triangularis. This species is entirely black, and so strong and muscu-
lar as to be difficult to hold in the hand when captured. The relation-
ship of this tribe of insects (Hydrophilus) with the preceding one
(Dytiscus) is very close. There is much similarity of form and a close
resemblance in habits ; their method of swimming, however, is differ-
ent, for while in Diyjtiscus both paddles are moved simultaneously, in
Hydrophilus they are moved alternately, hence the stroke of the latter is ¢
much less effective. We are not aware that anything has been written y
on the early stages of Hydrophilus triangularis, but in Europe the F |
life history of a closely allied species, Hydrophilus piceus, has been
carefully traced by several observers, and there is little doubt but that
our species has similar, if not identical habits. The female of H.
prceus has the singular habit of spinning a silky cocoon for her eggs,

inch long, which is supposed to be serviceable in conveying air to the interior. These
eggs, some fifty or sixty in number, are placed in an upright position and in regular order
in their receptacle, which is round and flattened and attached to some water plant at the
surface of the water. In warm weather the larve are hatched in from twelve to fifteen
days, when they escape at the lower part of the cocoon, which is closed only by a few
threads. They undergo three moultings, and when full grown measure nearly three inches

in length. The head is horny and of a very singular form, its lower surface being convex,
while its upper surface is flattened. Its sharp and formidable jaws are well adapted for
seizing and securing its prey. They are said to attain their full growth in July, when
they leave the water, bury themselves in the earth, where they undergo their changes in
a manner similar to that of Dytiscus.

Tue Tiger SwaLLowtalL (Papilio turnus.)

This beautiful in-
(49 sect has been more
than usually com-
mon in some dis-
tricts of our Pro-
vince during the
past year, and al-
ways attracts atten-
tion from its size
and its majestic
flight, floating
through the air as
it does in the most
stately manner. The
butterfly, Fig. 40,
measures about four
inches across, when
its wings are ex-

Fig. 40 panded; the body
is black above, margined with pale yellow, the wings yellow banded with black, the hind
pair powdered on their outer margin with patches of blue scales.

The caterpillar (Fig. 41) is rather a strange
looking creature, of an olive green colour, with
a whitish bloom and a prominent eye-like spot
on each side of the fourth segment. It feeds
chiefly on the apple, cherry, thorn and _ bass-
wood. Fora more detailed description of this
insect we refer our readers to the report of
Fig. 41. our Society for 1873.

THe AcHEMoN Spuinx (Philampelus achemon).

In our report for 1872
we published a descrip-
tion of this insect which
is a very beautiful and
attractive creature in
the perfect or moth state
(Fig. 42), anda very odd
looking object as seen
in the larval condition.
Quite recently Dr. John
H. Garnier, of Luck-
now, Ont., has written
us in reference to this
insect, which he has
found injuring his grape
vines. He found sever-
al of the larve feeding
{Fig. 42. on a Rebecca vine, for

——— =

which they seem to have a marked preference. He fed them in confinement and put in
leaves of Rebecca, Delaware, Massasoit, Concord, Creveling, Salem and Martha, but they
would eat only Rebecca leaves.

The caterpillar
(Fig. 43) varies much
in colour. When
young it is usually
green with a long
curved horn rising
from the last segment

a but one, but as it be-

Fig. 43. comes more mature,

in moulting the horn disappears, and its place is occupied by a dark polished tubercle ; the

colour also changes frequently to a pale straw or reddish brown, shading at the sides into
a rich brown. It has six irregular cream-coloured spots along each side.

When full grown it descends to the ground,
» and burrowing underneath, changes there into
Sa chrysalis, Fig. 44, of a dark shining mahog-
any brown colour. .
The moth (Fig. 42), which appears towards
Fig. 44. the latter end of June, is of a rich brownish-
grey colour, variegated with light brown, and with the dark spots, shewn in the figure,
deep brown. ‘The hind wings are pink, with a band of dark spots and a broad grey
border behind.

CATOCALA ULTRONIA.

In the genus Catocala is included a number of very beautiful moths, many of them
of large size, and restricted in their dis’ribution to the northern portions of America.
Most of them have the hind wings red, oanded with black, and hence have received the
common appellation of “ Red under-wings.” Some few species, however, have the red
ground replaced by white, or by plain black, or dark brown edged with white, but these
latter are greatly in the minority and much
less frequently met with than those with
red hind wings. The fore wings are
usually of varying shades of rich gray or
brown.

In Catocala ultronia (Fig. 45) the fore
wings are of a rich umber colour, darkest
along the hind margin, with. a broad dif-
fused ash-coloured band along the middle,
not extending to the apex, which is brown;
there are also several zigzag lines of brown

Fig. 45, and white crossing these wings. The hind
wings are deep red with a wide black band along the outer margin and a narrower band
of the same colour across the middle. The cilize which border the wings are partly white
and partly brown.

The larva feeds on the leaves of wild plum and is also found attacking the cultivated
varieties. When full grown, which is about the 20th of June, it is nearly two inches
long, a leech-like creature with its body thickest in the middle and tapering towards each
end. When at rest it adheres so closely to the bark of the branch and so nearly resem-
bles it in colour, that it is difficult to detect. The body is of a dull greyish-brown, studded
with brownish dots and rows of dull reddish tubercles. On the top of the ninth segment
or ring there is a stout fleshy horn, nearly upright, about one-twelfth of an inch long,
pointed and similar in colour to the body, but with an irregular greyish patch at each
side. On the twelfth segment there is a low fleshy ridge margined behind with deep
reddish brown and an oblique stripe of the same colour extends forward nearly to the

75

spiracle on this segment. The terminal segment is flattened and has a number of small
pale reddish and blackish tubercles scattered over its surface. Along the sides of the
body close to the under surface there is a thick fringe of short fleshy-looking hairs of a
delicate pink colour.

The under surface is also of a delicate pink, of a deeper shade along the middle, be-
coming bluish towards the margins with a central row of nearly round black spots which
are largest from the seventh to the eleventh segments inclusive. The anterior segments
are greenish-white tinted with rosy pink along the middle, with a dull reddish spot at
the base behind each pair of feet.

When about to change to a chrysalis the larva makes a rough enclosure by drawing
together fragments of leaves and fastening them with silken threads, within which it
undergoes its transformation and appears as a moth in about three weeks afterwards.

The moth is on the wing during the greater part of July and August, is attracted by
light and comes freely to sugar. All the insects of this family are night-flyers and expose
their brilliant hind wings only in flight. When at rest the grey or dull brown upper
wings overlap and cover up the gaily-tinted under wings like a very flat roof.

Tue lo Motru.—/ Saturnia io.)

The caterpillar of this moth is very pretty and is well represented in Fig. 46. It is of a
very delicate pea-green colour, with a broad white
stripe on each side, bordered with lilac below. The
body is covered with spreading clusters of green
bristles tipped with black, and when the larva is
handled these bristles sting like nettles. Judging
from the number of communications we have had
concerning this insect during the past year it must
have been very common in many quarters.

While quite young these caterpillars feed in flocks,
and have then the curious habit when moving from
place to place of marching in regular procession like
files of soldiers; when full grown, they lose this
habit and feed singly. They are very general
feeders and will eat corn, willow, hazel, sassafras,
wild cherry, elm, and a number of other trees and
plants. When full grown the larva crawls to the
ground, where, among loose leaves and rubbish, it
forms a rough outer covering, and within this a
slight cocoon of tough brown silk.

Fig. 46.
The moths are very handsome, an | are remarkable for the difference between the sexes
both in size and colour. The male (Fig.
47) is the smallest, and of a deep yellow
colour, with darker reddish lines and
spots. The hind wings are broadly
shaded with purple next to the body; near
the hinder margin is a curved purplish
band, and within this again is a smaller
one of a dark purple or violet colour. In
the centre of this last band, and in the
middle of the wing is a large round blue
spot with a whitish centre and a broad,
border almost black. The body is a
deep yellow, a little darker on the
Fig. 47. thorax ; the antennz are broadly toothed.

The female (Fig. 48) is
larger than the male, and
varies much in colour, from
a deep purplish brown to an
ochreous red. The fore wings
are covered by similar wavy
lines ; the inner margin is of a
darker colour ; the hind wings
are marked very similarly to
those of the male. These
moths fly only at night.

ced view of a native currant

Fs

currant bushes of our woods, but a more extended and inviting field
having been opened for it by the planting of the cultivated varieties
in our gardens, it has taken kindly to them, and although not so
destructive as the imported currant borer, Egeria tipuliformis Fig. 49.

i (Fig. 50), has in many instances, proved quite troublesome. In nearly all
our gardens numbers of the currant stalks annually perish, and were it not
for the vigorous growth of new shoots from year to year, the bushes would
soon be destroyed. If one of these stalks is split asunder, the cause of its
death is manifest, for through its whole length it is found to be more or

Fig. 50. —_less eaten away, the hollows being filled in places by a fine sawdust-like
powder. This is sometimes the work of the imported currant borer (Fig. 50), and some-
times the work of the native species (Fig. 49).

Early in June the parent beetle of the native currant borer deposits her eggs upon
the currant stalks, where they soon hatch into tiny grubs, which burrow into the heart of
the stem, and feeding on its pith, reach full growth before the close of the season. They
are footless grubs, which measure, when full-grown about half an inch in length. The
head is scarcely half as broad as the body, is of a dark brown colour, with black jaws.
The body is whitish with some brown dots along each side, and is slightly clothed with very
fine short hairs. When full-grown, and about to change to a chrysalis, the larva gnaws a
channel through the woody fibre to the outer bark, so that when changed to abeetle it can
make its escape by merely rupturing the bark. The cavity thus made is filled with little
chips to prevent the bark from being prematurely broken, and below this stuffing the
insect constructs a bed of short, woody fibres, packing the passage below with a finer ma-
terial resembling sawdust. Within this enclosure, which is about half an inch in length,
the larva changes to a chrysalis, and reposes until the fully formed beetle is ready to
emerge ; then gradually drawing away the obstacles to its egress, it finds its way to the
end of the passage, and gnawing a small round hole through the bark, effects its escape.

The Beetle is black with the edges of the wing covers and the thorax pale chestnut
brown. On each wing cover there is a rather large white spot beyond the middle, and
two smaller anterior spots, which are sometimes ash-grey and sometimes yellowish. The
antennx, which are shorter than the body, are pale brown, thickly clothed with short
ash-grey hairs. The under side is black and sparsely covered with short grey hairs.

Dr. Fitch describes two parasites which he found attacking this pest in the larval
state, one a small ichneumon fly, the other that of a small two-winged fly. Hence, secluded
as it seems to be within the centre of the currant stem, it is unable to escape the acute
instincts of its enemies, who searching it out, feed on its body and cause its death.

ats

As these worms remain in the dead stalks throughout the winter, their destruction is
easily compassed by breaking offall the dead wood to the surface of the ground and burning
it.

The imported currant borer is a pretty little wasp-like moth with a bluish black body
crossed by three narrow golden bands. It flies only during the warmer part of the day and
is very active in the hot sunhine. The female lays her eggs singly near the buds, and when
hatched the young larve eat their way to the central part of the stem as in the insect
just described, but instead of being footless this grub has sixteen feet, which are of a brown
colour while the body is fleshy white.

ON THE FLATERIDA OR CLICK-BEETLES.
By W. Hacue Harrineton, OTTawa.

This extensive and interesting family of Coleoptera has hitherto had but little atten-
tion devoted to it in these Annual Reports. Yet, it is one which deserves more than the
passing mention or description of a species, and the present paper is intended to call the
attention of our Agricultural readers to a large group of insects, which are now in some
measure destructive, and which may become far more so in the future. The facts will be
presented in as plain and untechnical a manner as is consistent with the scientific require-
ments of the case.

These beetles belong to the thirty-fifth family in Le Conte’s classification of Coleoptera,
and are a sub-division of the Serricornes of Latreille, being classed with the Sternoxt
(sharp-breasted). They are very nearly related to the family Buprestide, which were so
fully described in last year’s Report by Mr. Fletcher, differing, however, from the Bu-
prestians in being much more flattened and elongated, and less hard, They also have the
hinder angles of the thorax prolonged in sharp points, which prevent any lateral move-
ment of it. The thorax in most cases is very loosely articulated to the meso-thorax, al-
lowing considerable motion upward or downward of the front part of the body.

The pro-sternum (breast-bone) of the Buprestians was mentioned as being prolonged
backward into a point or spine, and this spine-like pro-sternal process forms one of the
most striking characteristics of the click-beetles. Our great teacher in scientific nomen-
clature, Linnzeus, gave to these beetles the name Elater, (from a Latin word meaning to
“bound,”) but this name is now strictly limited to one of the many genera comprised
in the Llateride.

The family is one very easy to determine, as the species preserve a marked resem-
blance to each other, varying but little in general shape, and going to no extremes in size
or colouring. Glancing at a collection of them, it will at once be seen that there is a pre-
ponderance of dull black or brownish species, with occasional touches of red or yellow,
but none are so brilliant as forcibly to individualize themselves by mere gay tints.
Roughly, they may be said to vary in size from a quarter inch to two inches.

They have been named click-beetles, skip-jacks, spring-beetles, snap-bugs, clickers,
snap-beetles and blacksmiths, from their power of leaping from their back, or from the
clicking noise which attends such a performance. By the celebrated Swammerdam they
were called grasshopper or locust-beetles.

As already stated, they belong to the great tribe of Serricornes, or ‘ saw-horned”
beetles, so named because the inside of the antenne presents a notched appearance, from
the joints having the tips more or less projecting. Their antenne are eleven-jointed, exr
cept in a few rare instances where an extra joint is found, and are placed widely apart.
In some genera they can be laid back under the thorax in grooves excavated along the
margins of the pro-sternum so as to be beautifully hidden and protected. The great ma-
jority of genera have these members of moderate length, and but slightly serrate ; but in
some few genera they are longer and pectinate, especially those of the males.

Click-beetles have rather short and slender legs, which can be folded very closely to
the body when the insect is alarmed. One of their most marked peculiarities of structure
is the spine into which the pro-sternum is produced. It is to be found between the first

78

pair of legs, and usually lies so hidden in a groove excavated for its reception in the
meso-sternum, that its use and importance might at first sight not be apparent. When,
however, the beetle falls, or is placed upon its back on a surface too smooth for any
projection to be reached with its short legs, the service rendered by this curious piece
of mechanism will soon be seen, for when the beetle has vainly endeavoured to right itself
by the use of its feet, and finds itself as helpless as a turtle in a similar predicament, it
bends back its thorax and head until its arched body rests only on the back of the head
and the tips of the elytra (wing-covers). By this movement the spine is released from
the groove or socket into which it so neatly fits; then by smartly bending up the
thorax again the projection is forced back into its receptacle. This is not so easily
accomplished as its withdrawal. It appears to catch for an instant upon the
margin of the groove, but by reason of its elasticity bends and springs in with a
sudden jerk, producing the snap or click which is heard. The consequent sud-
den impact of the elastic elytra on the hard surface tosses the beetle several times its own
length into the air, the height being greater as the substance on which it rests is smoother
and harder. If it does not fall upon its feet the operation is repeated until the desired
effect is accomplished.

Elaters may be roughly classed in two groups according as the larve are found feed-
ing on the roots of plants (usually under ground) or in old and decaying wood, or under
bark. The majority of the first, and a few of the second class are decidedly obnoxious
insects, while the rest are more or less beneficial.

The eggs of the root-feeders are thought (although the fact has, so far as I know,
never been actually determined by observation), to be laid on or among the roots or
stalks of plants, either in the ground or just at its surface. They are very minute globu-
lar, or partly oval bodies of a yellowish-white colour and produce almost invisible slender
grubs, which even when full grown are seldom more than an inch long.

In England these grubs have received the name of “ wireworms,” from their slender-
ness and hardness, and the same term is applied to them in this country. It is also in-
correctly applied sometimes to the millepedes or myriapods, such as the Julus, which is
found under stones or in wet wood, etc., and is often from two to three inches long. These
are not true insects and are easily distinguished from the larve of the clickers by their
many feet, the /ulus, for instance, having over fifty pairs.

The larv of elaters more nearly resemble in shape the well known meal-worms, or
grubs of the beetle called Tenebrio molitor. They have twelve segments besides the head,
and have six true legs ; also a prop-leg or tubercle on the least segment. They are semi-
cylindrical, being rounded above and flattened beneath, and are cased in a very hard,
horny covering, which affords them a most efficient protection from the attacks of their
smaller enemies, and also enables them to burrow easily and rapidly through light soils.

Such larvee as live in decaying or old wood are broader and more flattened and in
some cases much larger than the earth burrowers. The eggs are probably laid in crevices
of the bark or wood in which they undergo their transformations. These larve may be
said to be beneficial in so far as they, with those of many other tribes of insects, aid in
destroying and removing the decayed and prostrate vegetation, and thus make way for
new growths.

I am not aware that any very marked damage has as yet been inflicted upon the
crops in Canada by the larve of these beetles, but in the British Islands they have been
accused of committing alarming depredations on grain, root crops and garden produce of
various sorts. Much attention has been given to them by Curtis in his exhaustive trea-
tise on “ Farm Insects,” and also by many other well-known entomologists. A number
of species are described, four of which appear to be specially obnoxious and destructive.
The larvee live some years, perhaps as many as five, and moult, as do caterpillars, three
times before entering the pupa state. This change takes place in a small cell some dis-
tance under ground, and in a few weeks the beetles emerge to a higher but much briefer
existence, and are found upon various flowering plants, etc.

The four species so notorious for their ravages belong to the genera Athéus and
Agriotes of Eschscholtz, which are represente1in this country by a number of species,
having probably similar habits to their old world kindred.

There is scarcely any land free from them or any crop that is not subject to their
voracity. They occur wherever grass will grow, being particularly harboured among clover
roots, and are always prevalent in meadow and _ pasture-lands, seeming to thrive best in
the vicinity of swamps and woods. When lands are broken up the first crops sown are
often almost totally destroyed by the larve which infest it and remain in it for some
years afterwards.

Young oats, wheat, rye, barley, etc., suffer much from being partially or entirely cut
off below the surface ; the wireworms destroying manifold the amount actually devoured.
Wood says that while only eating one-tenth as much asa similar sized caterpillar, each
wireworm destroys ten times as many plants. Hops, cabbages and many root-crops are
also injured ; turnips, perhaps, more than any, as they are cut off when young, and have
the roots badly eaten into when larger, as many as twenty or more grubs having been
found at one turnip.

Conflicting opinions are held as regards the liability of potatoes to be attacked.
Some even propose the use of slices of these tubers, among other substances, as traps to
entice the wireworms to in gardens. On the other hand evidence has been often adduced
to prove that land sown with potatoes was in a great degree cleared of infesting larve,
which it was asserted do not touch the potatoes and are consequently starved out.

In gardens, the wireworms destroy salads, etc., and the gardener has also often tc lament
the loss of his beautiful flowers, such as carnations and lobelias. The list of cultivated
plants attacked by them could be greatly lengthened, and it is fortunate for Canadian
farmers'and gardeners that as yet they are not so abundant and destructive here. Never-
theless considerable damage is done to many crops on this continent, and the late esteemed
Dr. Asa B. Fitch (one of the greatest of American Entomologists) has treated of wire-
worms—see his 11th Report—almost as exhaustively as Mr. Curtis. It appears that
Indian corn, one of the largest and most important crops grown in North America, is the
greatest sufferer, especially when (as is usually the case), it is the first crop planted in new
land, or when the season is cold, wet and late. The seed corn is attacked by the wireworm,
which bores its way into the kernel and is often found half buried therein when the hills
are examined. Upwards of thirty or forty have been found in a single hill, and nearly
the whole of the seed planted is sometimes destroyed. The still more valued cereal, wheat,
does not escape serious attacks, and, as in England, a// crops are more or less liable to be
damaged. An exception may be made in favour of buckwheat, which has been strongly
asserted to rid the land of them, but there are doubts as to its efficacy in so doing,
as well as many objections to it as an uncertain and inferior crop. All kinds of
grasses, from the choicest timothy to the coarsest swamp sedges seem to be the chief
and favourite diet of wireworms ; so that grass and meadow lands are badly infested
for a year or two after being broken up.

Dr. Fitch was of opinion that the wireworms of this country do not live more
than two years (instead of five), as it is only for that length of time that new fields
are so much infested with them.

As the country becomes more densely settled, and, through the breaking up of the
waste lands, they are gradually deprived of their natural ,food-plants, they may come to
be equally abundant and voracious amongst us as in England, so that it may be well
briefly to mention the measures adopted to destroy them there.

For gardens or small lots hand picking is most strongly recommended as the surest
way of ridding them of these vermin ; but where labour is so scarce and dear as in this
country, such a measure is hardly feasible. By this method 18,000 wireworms were ga-
thered from a field of one and a half acres, and in another instance over 60,000 from an
area of three acres. Women or boys were employed to traverse the rows of plants, loosen
the soil around the roots, put all the wireworms into jars, or other suitable vessels, and
press down the soil around the roots.

One of the most successful remedies on a large scale is a mixture consisting of two
parts of quicklime, three parts of soot, and one part of coarse or refuse salt. This is used
as a top-dressing, being applied immediately after compounding, and should be well rolled
in. It has the advantage of being perfectly harmless to the crops. Indeed it is a most
excellent and powerful fertilizer, as well as a destroyer of all kinds of insects and many

80

weeds. Refuse from gas-works, nitrate of soda, rape-cake, and chloride of lime, mixed
and spread with manures are highly recommended, and the sowing of soda-ash or guano
broadcast when planting.

A previous crop of white mustard is claimed to clear the land of them, presumably
by starving out, for the roots of the mustard are extremely acrid, and of course occupy the
soil to the exclusion of afy more nutritive ones. A close grazing by sheep seems benefi-
cial where pastures are badly infested, perhaps because the surface is trodden down too
hard for the larve to work through, or because the beetles are prevented from laying their
eggs, or have them destroyed. The same result is also obtained by compacting the surface
by heavy rollers.

There are also means of striking directly at these pests which at the same time are of
more general utility, and whose adoption cannot be too strongly urged. Aside from any
mere questions of a taste for order, neatness and beauty, the practical wisdom and advan-
tages of keeping land thoroughly worked and cleaned are plain to everyone ; it does not
pay to leave neglected a single square yard of the farm.

The larvee of these beetles, in common with hosts of other insects, find a pleasant
refuge in the uncultivated patches left about the farm, and under or among stones and
other rubbish. Farmers cannot bear this too constantly in mind, and they should strive
to have their fields, as well as gardens, free from all unnecessary disfigurements of such
kinds. The entomological collector may delight in the rank growth of all manner off
shrubs and plants along the fences and ditches of his neighbours, for he generally finds a
rich variety of specimens thereon ; but ope is his gain is usually the owner’s and the |
country’s loss.

Leave no such strips along the ena snoes nor of stubble in the fields. Let all loose ©
boards, stones, logs, brush and rubbish of every kind be removed, and thus, as far as pos-
sible, prevent insect foes, from harbouring about the fields; there will be plenty of them —
without furnishing such breeding and hiding places.

Above all, learn to protect all their natural enemies, among the most powerful of
which are the birds. It is really disgraceful (and saddening to such as love and value
these bright little creatures) to see the merciless way in which they are shot and trapped
around this city (Ottawa), and I fear the same indiscriminate “slaughter of the innocents” —
takes place all over the land. All those that are known to be insectivorous should be
vigorously protected and encouraged, even if occasionally they do exhibit a tendency to a
vegetarian diet and pilfer a few berries and seeds.

Robins, thrushes, blackbirds, sparrows, etc., may be always seen searching and peck-
ing vigorously among the grass for elaters and other insects, while numerous species are —
searching for them in all other situations. It has been estimated that an English rookery, —
of 10,000 rooks, consumes annually about 200 tons of worms and insects. Now, our
much-abused crow, a brother of the rook, is just as active and voracious a bird, and feeds

its young (according to Fitch) almost solely on elaters and their larve. Thousands of —
these are probably consumed by the young crow before it even leaves the nest to hunt for
them itself. ,

Toads and frogs live also mainly upon insects, and being nocturnal in their habits— __
as are so many insects—they form the night relay, working to save the crops while the
birds are at rest. Turkeys, ducks and other poultry may profitably be allowed to run in |
grain fields at suitable seasons, while among root crops they can seldom do any harm, and ©
devour immense numbers of all kinds of insects. j

In breaking up new land it is well to burn the turf, and the destruction of many in- —
sects, in their various stages, is undoubtedly accomplished by the process of burning so —
generally in use inthis country.

When the elaters reach the perfect state, they are entirely harmless beetles (except
that they lay the eggs for future broods), and are found upon flowers, grass, stumps, trees,
fences, etc., and when they are approached they have a very common habit of dropping
from their resting- place, so that it is often almost impossible to find them. They walk ~
slowly, but can fly well, and do so both by day and night, seldom, however, making ~
long flights, rather preferring to remain in the vicinity of “their former feeding grounds.

As it is not proposed to attempt in this paper any scientific classification or descrip-

81

tion of the many genera and species comprised in the family Hlateride, the remainder
of this paper will be devoted to a few brief remarks on some of the more interesting for-
eign and native ones.

Westwood states that the Elaters are less rich in species than the Buprestians, but
that they are more generally distributed. About four hundred and fifty North American
species are given by Le Conte in his classification, of which, perhaps, one-fourth are found
in Canada. During the past summer I collected in the immediate vicinity of Ottawa
fifty species, while of Buprestians I only obtained about half that number.

There are perhaps no click-beetles that in form, size or markings are striking when com-
pared with many other families of beetles ; they vary but slightly in shape, are of moderate
size, and of dull hues generally. One genus, however, (Pyrophorus, containing 30 or
more species) is indeed worthy of notice from the power of light-emitting possessed by
its members. If sombre by day they are the brightest of all insects when darkness
shrouds the world. I have before me a specimen of P. noctelucus, the celebrated “ fire-
fly” of the West Indies and Central America, called by the Spaniards cucwo. Figure
51 represents this insect both at rest and on the wing. It is nearly an inch and a-half
long, (the elytra being exactly an inch from base to tips,) and has a tawny grey appear-
ance, caused by a covering of short yellowish hairs on a black surface.

Fig. 51.

Its most important features are two smooth, convex yellow spots, or tubercles, on
the thorax—one on either side—from which at night, when the beetle is alive, streams a
strong greenish light, far surpassing that of our own “fire-flies,” or, correctly speaking,
“ fire-beetles.” When the beetles are on the wing another patch beneath the body emits
a bright orange-tinted light.

These beetles and their larve feed on the sugar-cane and do great damage to the
plantations, being in some places very numerous, so that the air at night is starred in
every direction with their myriad meteor-like fires. The natives, ever ready to connect
the visible with the unseen, call them, not unpoetically, the vehicles of departed souls, or
in other places they are said to be the souls themselves flitting about the earth they have
left, so that to kill one might be to crush the soul of a departed friend. Such beliefs in
connection with certain insects, snakes, and other animals have often been prejudicial to
savage welfare by protecting obnoxious creatures from destruction.

P. pysoderus is a much smaller beetle, being but three quarters of an inch in length.
Its colour is a dark brown ; the hinder angles of the thorax are produced in acute spines,
and the tubercles are not prominent. It is common in the Southern States and emits a
light equal in intensity to that of our native “fire-flies,” but constant instead of inter-
mittent.

In the Phillipine Islands is found a very large species of Elater, called Oxynopterus
(sharp-winged) Cummingii. It is a large, reddish beetle and the male has fine pectinate
antenne, The prosternal spine is stated by Wood to be as large as a crow-quill, and three-
fourths of an inch long, so that its powers of leaping and clicking must be well marked.

The genus Pachyderes is distinguished by having the thorax twice as broad as the
elytra ; Semioti has the tips of the elytra spined ; and the males of Macromalocera, from
Swan River, Australia, have the antenne as long or even longer than the body.

Of seventy species found in Great Britain, the largest is Ludius ferrugineous, a dirty
red beetle about an inch long.

Turning now to Canadian beetles, the first sub-family is named Huenemide, and
comprises a few small compressed beetles found under bark or on leaves, and rather un-
common. Wood says that the prothorax in these species fits too tightly against the base
of the elytra to admit of them leaping, but Le Conte claims for some a feeble power to
do so. The second sub-family Cerophytide consists also of a few species of small beetles,
living under bark, and rarely, from their size and habits, seen or captured.

The third and last bears the family name—Hlateride—and includes all of our re-
maining species. Of these the largest and most striking examples are contained in the
genus Alaus (meaning “dull” coloured). There are four species found in Northern
America, viz.: Melanops, Gorgops, Occulatus and Myops, of which the two last (at least)

fre. wo y are found in Canada. A. occulatus (Fig. 52), must be familiar to
nearly all my readers, and is the largest of our Elaters, varying in
length from one and a quarter inches to one and three quarters.

Its general colour is a deep glossy black ; the under surface of the
body, and the legs being thickly powdered with white. The broad,
almost square, thorax is also powdered (but usually much rubbed),
with the exception of two large, oval spots of arich black velvety ap-
pearance, and rimmed with white so as to seem like great staring eyes,
often causing the thorax to be mistaken for the head by those ignor-
ant of an insect’s construction. These beautiful markings have deter-
mined its specific name ; for occu/atus is simply the Latin form of

“eyed.” The elytra are marked by longitudinal, impressed lines,
¥ and are sprinkled with bright white spots, of the same powdery
Fig. 52. substance which covers the rest of the body.

In early summer it is found crawling slowly, or sunning itself on trees, fences, build-
ings, paths, etc., and is easily captured. In Duncan’s “ Transformations of Insects” the
larva is shown crawling on the ground, and the pupa in a cell beneath the surface, but
Dr. Harris states that ‘it undergoes its transformations in the trunks of trees.” He
found them in old apple trees—the larvee feeding upon the wood. The following is a por-
tion of his description :— e

“These larve are reddish-yellow grubs, proportionately much broader than the other
kinds, and very much flattened. One of them, which was found fully-grown early in
April, measured two inches and a half in length, and nearly four-tenths of an inch across
the middle of the body, and was not much narrowed at either extremity. The head was
broad, brownish and rough above.”

Soon after the grub was found it cast its skin and entered the pupa state, and at the
proper time emerged asa beetle.

A myops is a somewhat smaller and less robust beetle, and varies more in size, some
in my collection being only one inch long. In general appearance it is much like occule-
tus, but is not nearly so handsome an insect. The markings are less distinct, the colour-
ing more greyish, and the eye-like spots on the thorax are much smaller and duller, whence
it has received its name of myops, or the “‘ short-sighted ” alaus.

It is much more common in this neighbourhood than occulatus. To show how readily

$3

these thoracic markings are mistaken for the elater’s eyes, and the loose articulation of
the thorax for the neck, I may just mention that a friend of mine brought me, one day
this summer, a fine large myops, which he had just found on his window-sill, remarking
that he was afraid it was dead, because “its neck seemed broken.” I told him to lay it
on its back upon my table, and the sudden snap with which it nearly sprang into his
face quite startled him. The Indian name for an elater (according to Dr. F itch) is “ neck-
breaker,” or “the insect that breaks its neck,” which gives a very good idea of its chief
characteristic.

Perhaps the most abundant of our elaters is a dark brown one, about half an inch
long, named Melanotus communis. The larve feed in wood, transform in the autumn, and
the beetles winter under bark or in crevices, and are very common in spring. Limonius
plebejus is also a brownish beetle, which is even more numerous in this vicinity.

Occasionally large glossy black elaters are found under stones in damp localities.
These belong to the genus Melanactes and are remarkable for having luminous larve.
Several species of Corymbites are numerous on pine-trees in summer, as C. wripennis,
C. hieroglyphicns and C. triundulatus ; the latter is also said to feed on the flower of the
rhubarb. C. vernalis, a pretty beetle with a black thorax, and yellow elytra marked by
five black spots, may be found sometimes in large numbers on blossoms of the choke-
cherry.

In the fourth volume of the Canadian Entomologist, an interesting account of the
wheat wire-worm, Agriotes mancus, is given by Mr. J. Pettit, of Grimsby, Ont., a very
careful observer. Mr. Pettit says:

“For many years an insect, familiarly known among farmers as the ‘ wire-worm,’
has committed ravages from time to time among the wheat crops in different parts of the
Province. As the history of this insect has not hitherto been traced out, I am happy to
be able to make public through the pages of the Canadian Entomologist, the following
description of its larval and pupal states.

“In the fall of the year 1870, so unusual an amount of damage was inflicted upon the
wheat crops in this vicinity by this wire-worm that I was led to try and breed it to the
perfect state with a view to ascertaining what species it was the larva of. By digging

< ek =|] 2 zp op p Te Q) about a dozen specimens (Fig. 53) which were
7 AMEE | placed with a few wheat plants in a large flower-

Fig. 53. pot, where they were kept supplied with food
by planting occasionally a small quantity of wheat. With the first cold weather they
ceased to eat, and were then placed in a sheltered situation until the return of warm
weather in spring, when they were restored to the breeding-cage. They soon gave evi-

~ dence of being alive, and possessing unimpaired appetites ; their
rapid consumption of the wheat plants rendered it necessary to
renew the supply quite as often as before. They were fed in this
way until the month of July, when my absence from home caused
them to be neglected ; on my return there was nota vestige of
food left. Thinking that the worms had probably died of starva-
tion, I paid no further attention to them until the 26th of August,
when, on removing a part of the earth from the pot, a pupa (Fig.
54) was disclosed, and on the 3rd of September the first imago ap-
peared, which proved to be a specimen of Agriotes mancus (Say).
Fig. 54. As only two more specimens came out during the remainder of Sep-
tember,I turned the earth out of the pot and carefully examined it. The inspection re-
vealed seven specimens of the imago in the little cells in which they had transformed, and
one larva. .

“‘ Among the larve collected, I had noticed one less than half the size of the others
and evidently much younger, which would account for the one still in the larval state. It
had attained, however, a size fully equal to that of the others when first brought in during
the previous autumn ; and hence I have formed the opinion that the larval state does not
last longer than three years. This opinion has since been strengthened by the observation
of a large number of larva which appeared readily separable into two sizes, corresponding

S4

to those originally collected for breeding. Westwood, in his ‘Modern Classification of
Insects,’ (vol. 1, 238), states respecting the larva of an allied species (A. obscurus) which,
in Europe, feeds upon the roots of wheat, rye, oats, barley and grass, that according to
Bjerkander, a Swedish naturalist, ‘it is five years in arriving at the perfect state.’ Cur-
tis, in his ‘Farm Insects,’ (page 16,), makes a similar statement upon the same authority,
and adds that those which he had himself fed for ten or twelve months scarcely increased
in size during that time. As already stated, however, I am of opinion that our species is
by no means so long lived, but that it attains maturity in three years, a period quite long
enough, the agriculturist must think, in which to inflict damage upon the crops.”

Fig. 53 shews the larva or worm magnified to about twice its natural size, and Fig,
54 the chrysalis under and upper side, also magnified—the hair line between them gives
the natural size.

The perfect beetle is about seven-twentieths of an inch long, the body black, punc-
tured with minute dots, and covered with very short hair, the head is large and black, the
antenne and feet reddish.

Adelocera is a genus comprising rather large beetles of a roughish, and often frosted,
or rusty, appearance. Their larve feed in decaying wood and are generally found upon
stumps, trees or fences.

The last genus which I shall mention here, viz.:—Pztyobius, is remarkable from
having twelve-jointed antennz, which in the males are beautifully bi-pectinate ; that is —
they have on each side spines, or branches, projecting from the joints. There are only
two species known in Canada—P. anguinus and P. Billingsii—and the beetles are exceed-
ingly rare, while but little is known of their habits.

P. anguinus “is of a dull black colour, with short brown hair.” P. Billingsit (named
after its discoverer, the late Mr. Billings, of Ottawa), has rich and rather glossy black
elytra, longitudinally lined, and wider than the thorax. The head and thorax are also
deep black but are roughened; the legs and under parts are less black. The head is —
nearly square above ; the eyes are very prominent, being far more conspicuous than in
any other of our elaters, which I have seen.

The specimen now before me is about one and a quarter inches long and is decidedly —
the handsomest click-beetle in my collection. It is probably the second specimen captured
and the only one now in a Canadian collection. The larva of this beetle lives in decay-
ing wood, for I found a pupa almost in the heart of an old rotten log, two years ago.
Unfortunately the wood in which I kept it was allowed to become too dry, and in conse-
quence the elytra never expanded properly and the specimen was destroyed.

Let me conclude with a few words of advice, which have often been spoken by others,
but which will bear repeating. Every farmer and gardener will consult his best interests
by paying close attention to all the insects which he finds about his land, and by striving
to learn something of their habits). When a strange insect or larva is discovered,
endeavour to place a specimen in the hands of the nearest entomologist, who will be always —
glad to inform you whether its habits are injurious or beneficial to plant-life, or, if they
are unknown to him, to try and find out what they are.

THE PLUM CURCULIO (Conotrachelus nenuphar).
By B. Gott, Arkona.

[Figure 55 represents this insect in its various stages, a the larva, 6 the chrysalis, ¢_
the perfect beetle all magnified. The hair lines at the sides shew the natural size. |

For some considerable time past I have closely watched the operations of this
familiar insect, and my only apology for bringing again this hackneyed theme to the
notice of the public, is that the growing importance of the subject appears to demand it.
I purpose to shew in this paper that our fruit is at present in more danger from the
depredations of this insect, than from any other single enemy operating on it. Not-—
withstanding all that has been said and written about this pest, and the good advice
which has been given for its destruction, yet comparatively little is done systematically —

85

to destroy it. With the view therefore of directing
‘ special attention to the losses resulting from neglect of
the remedies at hand, I shall as briefly as possible review
the whole subject of this insect and its work, as well as
the remedies which have been suggested for it. This in-
sect was first described by Herbst, a German Entomologist,
as early as the year 1797. It is a foreign aggressor but
the date of its introduction is not known. It is thus ably
described by Dr. Harris, in his ‘Insects Injurious to Vege-
tation,” a work that should be in the hands of every fruit-
grower and agriculturist :

“This weevil, or curculio as it is often called, is a little
Fig. 55. rough, dark-brown or blackish beetle, looking like a dried
bud when it is shaken from the trees, which resemblance is increased by its habit
of drawing up its legs and bending its snout close to the lower side of its body,
and remaining for a time without motion, and seemingly lifeless. It is from three-
twentieths to one-fifth of an inch long, exclusive of the snout, which is rather
longer than the thorax and is bent under the breast, between the fore legs, when at rest.
Its colour is dark-brown, variegated with spots of white, ochre-yellow and black. The
thor ax is uneven ; the wing covers have several short ridges upon them, those on the
middle the of back forming two considerable humps of a black colour, behind which there is a
band of ochre-yellow and white. I have found these beetles as early as the 10th of March, and
have frequently caught them flying in the middle of the day. They begin to sting the
plums as soon as the fruit is set, and continue their operations till the middle of J uly, or
as some say, until the first of August. In doing this the beetle first makes a small cres-
cent-like incision with its snout in the skin of the plum, and then turning round, inserts
an egg in the wound. From one plum it goes to another until its store of eggs 1s ex-
hausted, so that where these beetles abound not a plum will escape being stung.” There
is some difference of opinion among Entomologists as to the number of broods matured in
a season, but I think that with us there is but one brood, and these the result of insects
emerging from ‘the ground in early spring. '

Its relation to fruit culture is very intimate, and the whole aspect of fruit growing is
affected more or less by the existence of this troublesome foe, to the great discouragement
of plum, apricot and nectarine culture, estimable fruits where they can be successfully
grown. We cannot, as some have done, tolerate this insect as a serviceable thinner of
the fruit, for we have found it to be a most relentless destroyer. The female insect makes
a crescent shaped incision in the fruit and deposits there a tiny egg which soon hatches ;
the young and tender grub at once works its way to the germ of the fruit and revels in
its nutritive juices. The seed germ being mutilated, a vital point is attacked, the fruit
loosens its hold on the tree and soon falls to the ground. This is exactly what is needed
by the larva for its development and subsequent escape. If the fruit had dried up and
maintained its hold on the tree the grub would probably have perished. On the ground
the fruit is kept cool and moist and as soon as the grub is fully grown it leaves the fruit
and enters at once under the soil where it is shortly changed to a chrysalis and patiently
waits in obscurity its perfect development.

Its rapid increase is a matter of concern to all growers of the plum as it is spreading
rapidly over every part of the Province where this fruit is grown. At a recent
meeting of the Fruit Growers’ Association of Ontario one of the members present ob-
served that “ A few years ago there were no curculios at Goderich, now they are there in
full force ; and plum growers are discouraged. It is not yet at Owen Sound, but it
will be by and by.” Thus it is gradually widening its field of operation and annually
increasing in numbers. On my own grounds as well as on those of my neighbours,
this fact has been painfully evident during the past year ; not a tree has escaped, and
even the peach, cherry, pear and apple were attacked.

So far as we know in this country the curculio is almost exempt from the attacks of
insect enemies. In the report of the Entomological Society for 1876 mention is made
of two parasites which have been discovered by Prof, Riley operating on this insect in

86

Missouri, namely, Sigalphus curculionis (Fig. 56) and,Porizon conotracheli (Fig. 57). 1
am not aware that these friendly insects have yet been taken in Ontario, but it is quite
possible that they may be working unobserved among us. A detailed description of
both these insects may be found in the Report for 1876.

Fig. 56. Fig. 57.

As already stated the curculio does not scruple, in the absence of the plum, to attack
the peach, pear and apple. I was greatly amused during last season in watching the
little Turk at his work upon our young pears and apples. I had a favourite pear tree the
fruit of which I had never before seen, which blossomed nicely and set some five speci-
mens, leading me to hope that I should be able to test their qualities when mature, but in
a few days, lo the crescent! the familiar distinguishing mark of our fruit enemy was
already seen upon them, and in time they all fell prematurely from the boughs. In many
instances the same insect was noticed working upon the apples. As I was gathering in
my winter apples, a few days ago, I came to a Northern Spy tree, a very large propor-
tion of whose fruit was exceedingly ill-shaped, especially all around the lower branches.
The fruit was disfigured by deep indentations and corresponding swellings or knobs.
Upon examination it was found that those indentures on the fruit contained the mark of
the familiar crescent of the plum curculio which probably will account for their deformed
appearance. It would appear that the insect had cut the tender skin of the young fruit,
which had interfered with the circulation and development in that place. The egg de-
posited had not hatched, or if it had the little grub had died. The crab-apples were by
far the worst affected ; scarcely a sample matured on many fine trees, and a number of
fine young Tetopsky apple trees were totally deprived of their promising crop by the
same enemy. Under such circumstances constant vigilance is necessary to secure a crop of
fruit, and if the annual increase of insect life goes on unchecked it is easily seen that
good fruit will become scarce and more expensive.

The remedies which have been recommended are numerous, and may be divided into
two classes, viz., those that kill and those that merely deter. Under the first class may be
mentioned jarring the trees and gathering up the insects. This is by far the best remedy at
present known. P. Barry, in his excellent work “The Fruit Garden,” says that this method
was first recommended by David Thomas, forty years ago,and that on their extensive grounds
it is suecessfully carried out. Mr. Downing also speaks highly of jarring, and recommends
that it be repeated daily as long as the insects continue to make their appearance. Re-
peated trials have proven beyond question that this rather tedious mode is a very effec-
tual one if persistedin. Ata late meeting of the Fruit Growers’ Association of Ontario, at
Sarnia, Mr. James Lambert, of Sarnia, said: ‘“ He had tried the jarring plan with three trees
and these were breaking down with fruit.” Page 33, of 1878. In the November number of
the Gardener's Monthly, just at hand, it is related of Mr. Cobleigh and Mr. Willard, of
Geneva, N. Y., who are noted and jextensive plum growers, “They practice shaking the
trees, but their method is different from any one we have met with before. They have
two light frames on which light muslin is spread. They look like huge barn doors but
they are very light. These are placed under the trees when they are to be shaken.
Then they have a long handled sort of crutch ; the arm-rester as we would say if it were
a crutch, being nicely padded to prevent injury to the bark. This is pushed up and the
branches jolted and the “little Turk” comes down and is killed by the boys when it falls on

87

the muslin. This is better than the old plan of striking on the trunk. It has to be done
every day, and it would be as well twice a day. Mr. Cobleigh finds it takes two hours
and-a-half to shake 1,600 trees. Abundant evidence is forthcoming to establish the effi-
ciency of this remedy.

Another method suggested is to plant the trees in swine or chicken yards, a plan
which has also been highly recommended. At the meeting of the Fruit Growers’ Associa-
tion already referred to, Mr. James Dougall, of Windsor, said, ‘‘I find that a hen and
her chickens cooped under the trees, devour a great many curculios, and secure me a crop
of plums.” We would, however, rather allow the fowls free roving over the fruit yard at
will. The Hon. Mr. Vidal, of Sarnia, said that ‘‘ Mr. Baubee made a hen-yard around
his plum trees, and had no more trouble with the curculio.” Mr. Barry says “ planting
the plum orchard adjoining the hog-pen is probably the easiest and best way of securing
a crop of plums.” Mr. J. J. Thomas in his admirable work, The American Fruit Cul-
turist, page 155, says, ‘experience has thoroughly established the efficiency of this method”
(the confinement of swine among the trees of the plum orchard), and adds, “ geese and hens
are to a limited extent useful in repelling or destroying the curculio.” Again the late
Dr. Kirtland, of Cleveland, Ohio, says, ‘‘ This insect in one season destroyed every plum
on my farm, excepting the crop of one tree in my swine lot ; that tree is bending under its
load of fruit.” Here we have excellent evidence of the efficiency of this remedy ; we
would say, plant your plum trees together in a lot by themselves, and securely fence them,
then as they begin to bear fruit, keep a sufficient number of hogs or fowls in the yard
during the curculio season. Some cultivators are in favour of keeping hogs thus confined
in the orchard during the whole of the summer season, as it is thought they greatly bene-
fit the soil by their constant rooting and stirring of it. These two are doubtless the most
valuable and efficient remedies known.

Careful picking up of the fallen fruit should, in every case, be attended to
where hogs or fowls have no access, and this before the larve of the curculio have
had time to escape into the ground. After being gathered they should be burnt or other-
wise boiled or steamed and given as food to swine.

The second class of remedies are those which merely deter the insect from attacking
the fruit. Planting the plum trees on hard, clay soil has been recommended as a preventa-
tive measure. Mr. Downing says, ‘‘ we have never known an instance of the curculio
being troublesome in a heavy soil.” This statement has been confirmed by observation in
my own neighbourhood, where I have noticed that on heavy clay soils a crop of plums
can usually be secured, and there are hundreds of acres of just such soil where I
believe that thousands of bushels of fine fruit might be annually produced.

It has also been recommended to plant plum trees close beside water-courses to pre-
vent the attacks of curculio, and there are many who have faith init ; we have seen trees
so planted perfectly loaded with fine fruit, although there was no water flowing at the
time. There are some, however, who deny the efficacy of this measure. J. J. Thomas
says ‘‘it was formerly supposed that the instinct of this insect would prevent it from de-
positing eggs on branches hanging over water, but recent experiments prove that it pos-
sesses no such sagacity.”

Covering the ground under the tree with lime, plaster, ashes or salt have been used
to prevent the attacks of curculio, and in many cases with apparent success. Very
recently Mr. M. Watson, of Thedford, told me of a friend of his who had tried plaster ;
he covered the ground under the tree with it and saved his crop of plums. There is also
evidence that salt is useful when properly used. Mr. Downing refers to instances where
it has been used with complete success; he says, ‘the best method of applying salt for the
plum weevil is to strew it pretty thickly over the surface when the punctured plums com-
mence to drop.” The use of lime is advocated in a similar manner; some also are in
favour of ashes.

Employing offensive odours in the form of smoke from oil or tar has also been well
spoken of, but these measures are of very doubtful efficacy, and if the insects were thus
driven from one part of the fruit crop they would usually take to another.

Making the ground hard and difficult to penetrate under the trees by plastering with
mortar or paying with stones or shells are measures which have been advocated, Mr,

88

A. Watson in the American Home Garden, says that the most promising remedy is to
‘‘pave closely under the tree with clam or oyster shells, the instinct of the insect leading
it to avoid depositing its eggs in fruit from which, when they drop, its progeny can find
no safe retreat.” Mr. Downing speaks of plum trees growing in hard trodden court-
yards which usually bear plentiful crops. Some have also recommended the use of chips
and small pieces of wood placed around the trees as traps for the curculio, but it is very
doubtful if any of these methods will ever take the place of jarring.

NATURE PRINTED BUTTERFLIES,
By James FLETCHER, OTTAWA, ONT.

The season of warm days, flowers, and butterflies is over now, and the look-out is
cold, bleak and bare. Apparently there is little for the scientific lover of nature to do in
the way of collections at this time of year; such however is far from being actually the
case, as all who have collected will testify. It is in fact one of the busiest seasons for
collectors. All the treasures gathered during the summer months have to be gone through.
In the first place those known have to be taken out and sorted away into their proper
places in the cabinet ; the remainder then have to be re-sorted and divided up into sets
according to the families to which they appear to belong, and after this they have to be
examined critically and if possible identified. It frequently happens that a collector of
butterflies has an opportunity of capturing a large number of some local species, in one
day, and finds it impossible or irksome to set them all before they become too dry, as they
will ina very short time in hot weather. When they are once dry, too, one is apt to think
that as they can get no worse they may safely be put aside until some more convenient
occasion to be relaxed and set up, but this convenient occasion, like a good many others,
is sometimes very long coming, and many valuable specimens are thus lost. An
aceident which occurred to the glass of one of my butterfly cabinet drawers lately,
was the means of reminding me of a process shewn me some years ago by a Cap-
tain Lloyd, of the English Navy. The accident referred to was the breaking of the
cover of one of my cases which contained some rare butterflies, in consequence of which
it was impossible to close the door of the cabinet tightly. My horror can be better
imagined than expressed when, upon opening the door and pulling out this drawer, about
a fortnight afterwards, I found that there was nota single perfect specimen in it—a
mouse had got in and what was once a neatly arranged case of butterflies was now
nothing but a chaos of nibbled bodies, loose wings, pins, and labels. I had not the heart
at first to throw out these fragments and so wipe out entirely the pleasing recollections
each brought up in my mind of rambles through the woods and in the country ; so care-
fully gathering up the wings I put them away in a little box. The idea then struck me
of printing them as I had seen my old friend do them—and as I think it would be a very
convenient way for Entomologists and agriculturists to send butterflies for identification,
when spare duplicates are to be had, I am induced to send a description of the modus
operandi. Take the insect in your left hand, holding it beneath the thorax, then with a pair
of sharply-pointed scissors cut off the wings as close to the body as possible ; occasionally,
unless the scissors are very sharp, some of the muscles are torn away from the thorax with
the wings, these must be carefully removed ; arrange the wings in pairs and put them
with the body on one side in some convenient place where they may be easily got at when
you are ready for them. Now take a piece of white paper of the size required, and fold it
in two like a sheet of note paper, then with a camel-hair brush lay on a thin wash of per-
fectly clear gum arabic, fold down the upper half and pass the hand lightly over it so as
to spread the gum evenly between the two sides ; now re-open it, and taking up the wings
with the tip of the brush, the lower ones first, arrange them carefully in the position
wanted, leaving space enough intervening between the two pairs to paint in the body
afterwards. Spare no pains in arranging the wings ; this corresponds with “setting” for
acabinet. I have seen many good collections of insects, made by amateurs, rendered al-
most useless by the want of a little thought on this.point. The proper position for a but-

terfly to be set in is that which it takes when sunning itself. Copy nature, and you cannot
go wrong. When the wings are quite even, gently fold down the upper half of the paper
and put your specimen under a heavy weight or in a press until quite dry—I generally
leave mine for some hours at least. When it is quite dry take it out and place it against a
window-pane, so that the butterfly may be clearly defined against the light. Now, very
carefully draw a line with a black lead pencil round the edge of the wings, then lay it down
on an even surface, and paint with clean water all over the part outside and up to the out-
line. After a few minutes the water will saturate the paper and dissolve the gum ; the
two sides will, then separate easily, and this being done it will be found that on one side
is a perfect representation of the upper side of the butterfly, on the opposite another of
the under side, and loose between these a perfectly clear horny membrane ; the explana-
tion of this is, the upper ends of the scales are adhering to the gum, and what we now
look at are the lower ends or roots. When painting with water, to dissolve the gum,
great care must be taken not to let it run over the outline on to the wings, or else the
scales will not adhere to the paper, but will remain on the membrane.

The work is not yet finished, however ; a most important part has still to be done ;
this is the filling in of the body and antenne ; the easiest way to do this is with a fine
pen and some water-colours. Place the body, from which the wings were severed, before
you and copy it, taking particular notice of any characteristic markings, as for instance,
the colour of the eyes, legs, or antenne. When finished, cut it out with a pair of sharp
scissors, paste it in an album and write a short description of its capture, giving the date,
locality and any other interesting circumstances connected with it. I have found it is
easier to put in the antenne after the prints are gummed into the collection as on account
of their fragility, they are difficult to cut out neatly. Should the collector happen to he
an artist, a most beautiful collection may be made in this manner by painting pretty
designs with flowers for each species, and gumming the butterflies in, in natural positions ;
of course too, its scientific value will be materially increased if those plants are introduced
to which the insect is most partial, and when possible, a sketch of the larva and pupa is
added.

The chief advantages of this process are, the ease with which it is done; the great
convenience with which the specimens are preserved or transmitted through the post for
identification or exchange ; their great durability, for they will stand much rougher
handling than specimens preserved in the ordinary way ; and more important than all these
the fact that if you have only one specimen, you can shew both the upper and under sides
at once, and also the membranous skeleton of the wings, which can thus be very easily
examined and makes a beautiful object for the microscope ; moreover, if you have only an
imperfect specimen it is possible to preserve a good likeness of it by filling in the wanting
parts with water-colours ; and further, it does not matter how old your specimens are ; I
have some prints which I have taken from butterflies collected in India more than twenty
years ago which are quite as good as others printed on the same day that the insects were
caught here.
