In August and September, making straight short incisions, about 
0.10 long, in the bark of the small limbs, particularly where tin- 
new growth of the year commences, and dropping a little cluster 
of minute eggs therein, which remain till the sap begins to cir¬ 
culate the following spring, when they hatch insects resembling 
small mites, which immediately wander away from the spot and 
subsist upon the juices of the leaves and green succulent twigs, 
which they puncture with their minute sharp beaks. These insects 
will be found fully grown in July and are then about 0.2S long
