PR EFACE. 



, This syllabus is not intended to take the place of a \ 

 / text book. It is simply a note book, in which are 1 

 noted the more important points discussed in the lec- 

 tures, and references to authors. 



My object in publishing it is to save the students a 

 part of the labor of taking and copying notes, thus 

 enabling them to give more time to the study of spec- 

 imens in the laboratory and in the field ; and to indi- 

 1 cate the best writings on the subjects discussed, that / 

 \ may be found in our library. 



The blank pages are for the taking of additional 

 notes during the lectures. The text book recom- 

 mended is Packard's Guide to the Study of Insects. 

 The titles of other Entomological works are given on 

 page 147. J. H. c.
