"The present manual attempts to bring together a brief yet com- 

 plete key to the families of American insects, unhampered by more 

 than the explanations needed to make such a tabulation available to 

 the general student. .. .Identification of the families has been effected 

 by means of analytical keys, which have been arranged as dichotomies 

 While the dichotomies frequently represent the natural relation- 

 ships or the lines of phyletic development, no attempt has been made 

 to preserve natural divisions wherever the convenience and practical 



operations of the keys would have been sacrificed The task of 



the writers has been little more than to compile from [the] existing
