remain surrounded with a little mass of white down, and cov- 

 ered with the dried body of the female, who expires as soon as 

 they are deposited. These eggs hatch rapidly, and the insects 

 issue from the shell which covers them, toward the end of June, 

 to the number of more than a thousand. Hardly visible to the 

 naked eye, they spread themselves over the surface of the 

 leaves and young shoots, and destroy them by piercing their 

 epidermis and absorbing their fluids. 



Toward the month of November, when the leaves fall, the 

 kermes abandon them and fix themselves on the branches, 

 choosing in preference, where the trees are en espalier^ the side 

 next the wall, where they remain torpid through the winter, 

 appearing like little brown stains. In the month of April they 

 change their skins, rapidly increase in size, and give birth to a 

 new generation. 



The measure-worm is the larva of a moth, which in the 

 spring greatly injures the vine by devouring the young shoots 

 as they are put forth. It is difHcult to find it, as it has the
