 plants, and toward the middle of summer it fastens its 

 eggs, with a gummy substance, upon the under sides 

 of the leaves of these plants. These eggs are soon 

 hatched, and the young, in company with the old 

 ones, proceed to suck with their reflected snout the 

 sap of those leaves and stems, often causing the whole 

 vine to wither and perish.

 their parents, are furnished with wings in the autumn, 

 and as soon as the inclemency of the weather and the 

 want of food obliges them to do so, they fly away % 

 take possession of their winter-quarters, in the holes

 trees.
