1 No attempt was made to review the various species of Aphididse abundant alike on trees, shrubs, and herbage. 
Likewise the Coceidae were not studied. The inter-relationships existing between these families and the various 
species of lace-wing flies, lady-bird beetles, and ants are, of course, important, as well as the interaction between these 
same families and the food-plants which their species severally affect.
