affecting the Com- Crops. 
The eggs are hatched at 110^ Fahr., whilst 130' to 140° killed 
them. 
A room heated to 135^ by hot water-pipes has been constructed 
in Madeira, which answers every purpose. 
The tcheat subjected to this high temperature vegetated in the 
ground. 
In Norfolk the windows of an empty granary are set open for 
two or three nights during a frost, which expels the Weevils. 
Fleeces of wool laid on the corn-heaps attract and kill the 
Weevils. 
In London the malt does not suffer from these pests when 
white-washing the granaries and hequendy stij'ring or turning over 
the heaps are regularly attended to. 
A little beetle, called Silvanus Surinamensis, with its larvae and 
pupae, sometimes abound in granaries. 
It inhabits bran also, and is found under the bark of trees. 
A smaller beetle, called Cucujus testaceus, has been found in 
great abundance in granaries and mills. It has also been detected 
under the bark of elm-trees in December. 
Inhabited the loheat from Ancona, with its larva. 
Another species, the Cucujus minutus. infests the maize. 
Ptiims crenatus often accompanies them, eating into the floors 
and tcood-work. 
Kyanizing the timber used, the best remedy against their 
inroads. 
Uloma cornuta is a beetle, which inhabits the maize-spikes, and 
is often found in London bread. 
The Cadelle is the larva of a beetle which is mischievous in 
granaries, especially in the south of France. 
It inhabits also dead trees, and will attack bread and dried 
fruit. 
It has been imported, and a colony of them Avas found in the 
floor of a malt-house in Cambridge. 
It was bred from a Spanish almond, in which it lived as a larva 
and beetle for three gears. 
The Cadelle eats the outside of the grain, injuring more than it 
consumes. 
These larvcB are most troublesome at the end of winter, and 
become pupce in the earth or amongst dust. 
The beetle is called Trogosita Mauritanica, and devours the 
, Tinea granella. 
These insects ground up with our food, in all probability inju- 
rious to the constitution. 
Chocolate sometimes manufactured from cocoa-nuts swarming 
with insects.
