of the forester, of being able to recognize such species and dis- 

 tinguish them from the truly injurious forms. 



There are no keys, but descriptions of all the species dealt 

 with are given and a very large proportion are figured. Unfor- 

 tunately a great many new species are described, an undesirable 

 feature in an economic treatise. This was perhaps difficult to 

 avoid, however, in the present work, as it is possible that the 

 publication of so many new species in the regular journals might 

 have caused serious delay in the issue of the book. 



The illustrations include 6-i plates, of which 7 are colored, 

 and 401 text figures. They are of very variable quality, being 

 the work of several different artists. The great majority are 

 excellent in every respect, some of the plates, such as Plate XV, 

 on which a group of Buprestids is shown in color, being of great 

 beauty and finish. Some of the colored plates, however, are 

 poor, and among the text figures are a few exceedingly crude 

 sketches, which look like rough field notes that had never been 

 intended for reproduction. 



As a pioneer effort in the study of Indian forest insects, the 

 book is deserving of great praise and will undoubtedly be the 

 most useful work on the subject of Indian forest beetles for 

 many years hence. We look forward with pleasure to the 

 appearance of the next volume in this series.

For years this insect was known as an enemy of pine in the 

 East. More recently it was found by forest entomologists to 

 be a rather serious enemy of second growth pine, especially Yel- 

 low pine, also in the West. While of secondary importance eco- 

 nomically, it is largely a primary insect physiologically as regards 

 the trees it attacks. From the standpoint of pure science the life 

 history of any insect is capable of yielding facts that may shed 

 light on hitherto obscure points in one or more phases of general 

 biology. From the economic standpoint we have had repeated 

 occasion to be impressed with the importance of knowing every-
