which are briefly mentioned in the preceding- chap- 
ters. This tribe of insects is generally known to 
be a great pest to a variety of trees, shrubs and 
flowers. 
The Destruction of the various species may 
be performed as severally directed for the Acarus 
upon the Apple tree ; the Acarus Telarius, and 
another sjiecies, upon Peach and Nectarines j and 
the species on the Gooseberry. 
Coccus or Scale. — The various species of 
this genus do not confine themselves to one species 
or tribe of plants, but will be found to feed on 
most kinds of trees and shrubs. Where they 
happen to exist, the same means may be used as 
described for the Coccus on the Pear; Coccus 
on the Apricot; Coccus on the Vine; and Coccus 
on the Berry bush. Similar attention will be 
necessary for the destruction of other species not 
mentioned in this work. 
The larvjB of the small Fly, which causes 
brown spots on the leaves of different kinds of 
plants, can only be destroyed by the method laid 
down for its destruction on the Pear tree. 
The Thrip. — Only one kind appears to have 
presented itself. It is so troublesome, that I am 
persuaded few practical gardeners are unacquainted, 
with it. For description of it, and means for its 
destruction, see Peach and Nectarine tree. 
For directions as to the Larvae of the House 
Fly feeding on Cauliflowers, Turnips, Onions,
