lectures on the more important insect pests and on methods of controlling 

 them. The practical exercises will include a study of the different stages of 

 as many of the forms as time will permit, together with observations in the 

 field on the habits of the pests 



4. Elementary Morphology of Insects. An introductory laboratory course 

 required of all students who plan to do advanced work in the Department 

 of Entomology. 



5. Elementary Systematic Entomology. A study of the wing venation of 

 insects and the identification of specimens belonging to the more important 

 orders and families. With course 4, required of all students who plan to do 

 advanced work in the Department of Entomology. 



6. Advanced Systematic Entomology. A training course in the identifica- 

 tion and interpretation of obscure characteristics used in the classification of 

 insects. 



7. Histology of Insects. A laboratory course to accompany or follow the 

 first term of course 12. 



9. Advanced Economic Entomology and Insectary Methods. Economic 

 problems connected with applied entomology, discussed, reported upon, and 

 field observations made. Experimental methods in breeding, photographing, 

 investigating, and controlling insects discussed and studied. Designed for 

 advanced students in entomology who desire to fit themselves for experiment 

 station work.
