Dr. A. Fitch, and Dr. C. V. Riley, the Illinois Entomological 

 Reports, and the Entomological Reports of the Departments of 

 the Interior, and of Agriculture, will also be found of great 

 value and interest. Cresson's Synopsis, already referred to, 

 will be indispensable to every student of bees or other Hyme- 

 nopterous insects. Smith's Entomology and Comstock's En- 

 tomology are indispensable to every person at all interested in 

 Entomology. The Reports of the several Experiment Stations, 

 especially New Jersey and Cornell, are of great value. (See 

 " Bibliography " at the close of the first part of this volume.)
