OF INSECTS, &C. 3.^3 



is, In general, so small as to be scarcely discerned 

 by the naked eye. It is, however, very pernicious 

 to fruit-trees, sometimes attacking the fruit as well 

 as the leaves. To destroy this insect, follow the 

 directions given for destroying the Coccus. 



The Phalcena, or Moth. 



There are numerous species of this well known 

 insect, and their caterpillars differ greatly as to size, 

 shape, and colour. All of them, after casting their 

 slough several times, spin their cod, in which they 

 are transformed to chrysalids. They are frequently 

 found in this state, rolled up in the leaves of fruit- 

 trees, particularly those of Pears, Plums, and 

 Cherries. These leaves must be carefully picked 

 off, and the insects crushed : the trees must then 

 be washed with clear lime-water, mixed with to- 

 bacco-water. This washing would be found usefu^ 

 when the insect is in its larva state, after picking 

 off and crushing as many of the caterpillars as pos- 

 sible. See Caterpillars. (Page 346.) 



Spinx, or Hawk-moth, 



There are one hundred and sixty-five species of 

 this genus, ten of which are found in Great Britain 

 and Ireland. 



The name of Sphinx is given to this genus on 

 account of the singular attitudes of their cater-
