 of Aphis pomi which were commenced in 1913 and carried on at Vienna, Va., 

 The outline of the life history prepared by the authors is as follows : 



" The egg is laid upon the tender twigs of the apple, though occasionally it 

 is laid upon the bark of the older twigs. It is light yellow when laid, but later 

 changes to shining black. Development for a few days is very rapid, after 

 which the egg rests for the winter. When the revolution of the embryo is 

 completed in the spring, an increase in temperature will cause the egg to hatch.
