A PREFACE 



literature is found in the summarized accounts of some of the more inter- 

 esting groups one meets in the study of forest entomology. These latter 

 are of special value in giving a general knowledge of the subject, some- 

 thing which appeals strongly to those having a comparatively slight 

 knowledo-e of entomology, yet desirous of following in a general way, the 

 manifestations of insect life. Some original morphologic studies are also 

 included in the volume, since they are almost essential to the adequate 

 identification of certain very injurious species.
