For many years the most pressing demand of teachers and learners in entomology in this country has been for a handbook by means of which the names and relative affinities of insects may be determined in some such way as plants are classified by the aid of the well-known manuals of botany. But, as the science of entomology is still in its infancy, the preparation of such a handbook has been impossible. Excellent treatises on particular groups of insects have been published ;but no general work including analytical keys to all the orders and families has appeared. It is to meet this need that this work has been prepared. The reader must not expect, however, to find that degree of completeness in this work which exists in the manuals of flowering plants. The number of species of insects is so great that a work including adequate descriptions of all those occurring in our fauna would rival in size one of the larger encyclopaedias. It is obvious that such a work is not what is needed by the teachers and students in our schools, even if it were possible to prepare it. An elementary work on systematic entomology will always of necessity be restricted to a discussion of the characteristics of the orders and families, and descriptions of a few species as illustrations. Complete synopses of species will be appropriate only in works treating of limited groups.
