THE GARDENERS CHRONICLE. 
[AUGUST 8, 1874. 
The Entomological Exhibition of 1874 com- 
prises four divisions. In the first are to be 
included all useful insects, which are to be 
shown, as far as possible e, in various stages, 
from hoe egg to the perfect insect. If diseased 
the insect is to be shown in different stages of 
the disorder. Insect-products also will be shown 
in their various stages of formation. The 
plants on which the insect feeds are also to be 
shown. Monographs and works relating to the 
subject will likewise be exhibit: nformation 
is requested as to the losses occasioned by 
insects, and it is incidentally mentioned that 
the losses occasioned by the silkworm disease 
gs have amounted since 1854 to more 
an 60 millions of francs yearly. The second 
aac of the exhibition is intended to com- 
prise noxious insects, divided into 
arranged according to bs —_ tigen each 
insect being separately s six first 
classes thus include all cultivated Ris in- 
cluding fruit and forest tre The seventh 
rs, 
insects parasitical on man and domestic 
animals. Here, again, as far as possible, the 
object is to show the insect in all its stages, and 
to add notes on its habits and transformations, 
Monographs ; are requested of a descriptive 
a the insects in question being for the 
ost part well known, but such as will elucidate 
eg habits of the insects. 
The losses caused by to agriculture 
may be estimated by Ibundireds of millions of 
Dacus in the case of the Olive, &c. 
The third division comprises those parasitic 
insects which wage war against the aphides, 
caterpillars, &c., not omitting the mole and the 
-hedge-hog and insectivorous birds. The 
inte word 
or rather extending its operations to 
includes i pro- 
snails and slugs, and the mode of 
ing their ravages, the culture of fishes, 
leeches, and “astaciculture”—cray fish !—thus 
comprising aquaria of various descriptions. 
It is not sufficient, say the promoters, in con- 
tinuation, to collect together all the insects and 
insect-products of general interest to can 
it is desirable also to oe together th culti 
ord 
y coc 
- &c. Relating to p Phylloxera 
: of the Vine, it is asked whether it is the „cause, 
or only a resi Ae or the i How it ii is that 
oo in Europe is, or is they hentia Sk ae te 
insect in America? Whether there is known 
one or more parasites affecting the Phylloxera ? 
er there are any particular varieties of 
Vines which are not a by this insect, 
and whether they can be propagated in France ? 
__ What is the probable amount of loss caused by 
eight classes, » 
the insect, and what effect it has on the price of 
wine, its consumption, the infiuence on railway 
transit and taxation generally ? 
Questions are also propounded as to the best 
method of rearing silkworms, so as to escape 
the diseases affecting them, such as Muscardine, 
ebrine, &c.; and other inquiries are made as 
to the value of the silkworms raised on the 
Ailantus aoe Oak respectively. 
t will seen that he Exhibition and 
obese are of the most directly interesting 
and practical nature, and it is to be hoped that 
much benefit may accrue from them. Exhibitors 
and others desirous of au part should apply 
to the secretary, Rue Monge, 59, Paris, on or 
before ec mem bes I, for fete particulars,
