wall trees to a considerable height, and destroy 
the fruit, leaves, and young shoots, and will annoy 
most other plants falling in their way. 
Wet, damp, mild weather is most agreeable 
to them, and they may be met with early in a 
morning or late on a evening, also in cloudy, 
showery weather, in the day-time. The most 
ready way of destroying them will be to gather 
them by the hand. They may also be attracted 
in the way directed for the Slug. Lime will 
completely destroy all species when thrown upon 
them. The lime-water is not quite so effectual. 
Salt will destroy both the Slug and Snails, but 
seldom without a second application, except thick- 
ly laid on. The lime, however, kills them more 
readily, and can be used without injury to the 
plants, and at less expense. 
It must not be supposed that any application 
to the ground or plants promiscuously, will have 
any effect in destroying them, when they are in 
their harbours, as they will be sure to abstain 
from feeding' or coming out upon either the salt or 
lime, till the effect is lost. 
The Chermis genus is found to prey upon 
the foliage of a great variety of trees, shrubs, and 
flowers. The kinds presenting themselves to my 
notice are small, scarcely so large as a middle-sized 
Aphis, but very different in shape. They ap- 
proach in miniature, near to the form of some of 
the smaller Moths, furnished with four transpar- 
ent wings, about twice tlie length of tlie l)0(ly
