begins to deposit her eggs early in June; they are placed 

 singly within little semicircular incisions through the skin 

 of the leaf, sometimes on the under side and sometimes on

 oozes out of the skin and covers the upper part of the body 

 with an olive-colored sticky coating." A second brood of 

 eggs is deposited late in July. Maturing in about a month 

 they go into the ground and assume the pupa state, in 

 which form they remain during the winter.

 it. A wash, composed of an ounce of powdered hellebore 

 to each two gallons of water, sprayed on the leaves of the 

 tree is sufficient.
