An Introduction to Entomology 



By JOHN HENRY COMSTOCK, Professor of Entomology and General Invertebrate 

 Zoology, Emeritus in Cornell University. 



* PART I — The Structure and Metamorphosis of Insects 



This volume is the first part of a text-book of entomology that Professor Comstock has 

 in preparation. It is, however, a complete treatise on the structure* and metamorphosis of in- 

 sects. The part now published includes four chapters. The first chapter is entitled " The 

 Characteristics of Insects and Their Near Relatives." In this chapter the characteristics of 

 the Arthropoda and of each of the thirteen classes of arthropods is discussed, with figures of 

 representatives of each of these classes. The second chapter is devoted to a detailed discussion 

 of the external anatomy of insects. The third chapter treats of the internal anatomy of in- 

 sects and includes the results of recent investigations in this field. In the fourth chapter there 

 is a detailed account of the transformation of insects, in which each of the difierent types of 

 metamorphosis of insects is discussed. There is also included a bibliography and an index.
