When the tree-bug, , Faun. Suec. 700. has 
depofited its eggs in the boughs of the fir tree^ 
excrefences arife lhaped like peas. When an- 
other fpecies of the tree-bug , Fn. 695. has 
depofited its eggs in the moufe-ear chickweed 
or the fpeedwell, FI. 12. the leaves contract in 
a wonderfull manner into the fhape of a head.

poplar , from whence a red globe is produced. 
The tree-loufe , Fn. 1355. lays its eggs on 
the leaves of black poplar, FI. 821. which 
from thence turn into a kind of inflated bag,

only that infers live, and lay their eggs. The 
knats , Fn. 1116. commit theirs to ftagna-

the appearance of blood. Others lay their eggs 
in other places, e. g. the beetle in dunghills.
