Jnlus pulchelbis inhabits both fields and gardens, and is widely 
spread over England. 
Julus Londinensis infests the roots of wheat in April. 
Julus terrestris is found in rotten fruit, &c. 
Julus punctatus inhabits moss on trees, and resides under stones. 
Julus latestriatus : thousands infested a garden and greenhouse, 
destroying cabbages and potted plants. 
Julus pilosiis lives in cabbage-roots in March. 
Pohjdcsmus complanatus is said to be the most destructive 
species, eating the roots of wheat and destroying onions and 
garden flowers. 
Snake-millipedes feed upon animal as well as vegetable sub- 
stances, such as snails and earth worms ; and in addition to the 
plants already alluded to, potatoes, turnips, the entire tribe of 
cabbages, beans, peas, carrots, &c., suffer from their attacks. 
When the Snake-millipedes walk they glide along, and curl 
tliemselves up spirally when at rest. 
They live tioo years before they can procreate their species, 
and change their skins five times. 
The females lay a great number of minute eggs in the earth, 
from Christmas to the middle of spring. 
The young when first hatched have only six legs, which increase 
with age uniil they have from 150 to 240. 
Application of artificial heat and hand-picking the most certain 
remedies. 
They cannot live without moisture. 
The application of lime probably would be serviceable where 
they abound, especially lime-ivater. 
Soot spread over the land will drive them away. 
Sowing nitrate of soda, ox. watering the crops with a solution, 
might destroy them. 
Dull damp days the best for this operation, and never attempt 
it when the sun shines upon the crop. 
Baskets filled with damp moss, and sunk in the earth, misrht be 
employed in gardens as traps to decoy them, especially during 
droughts. 
They will be found under clods and stones in fields, pastures, 
&c. 
Old cabbage-leaves, if strewed over fields, would attract them, 
where they are numerous and hand-picking is resorted to.
