the subject. Dr. Felt’s new book is one of the Rural Manuals and is of convenient 
size and generally attractive make-up. It is arranged in three parts: Part I contains 
general information about the structure, transformations and origin of insects, a list 
of introduced pests, literature, and accounts of the natural checks and artificial 
methods of controlling insect pests. Part II contains a brief account of each of the 
more important shade tree insects grouped according to the particular kind of injury 
which they cause. Part III deals in a similar manner with forest insects, and Part IV 
is a systematic account of the more important orders of insects, each order being 
illustrated by a few species connected with trees or shrubs. 
In any work of this size and scope, much must be omitted, and many species in¬ 
cluded by mention only. Probably no two entomologists would agree on just what 
species should be included or their relative importance. Nevertheless, the critical 
reader may wonder why twenty-two pages are devoted to “Plant Galls and Gall 
Insects” when only twenty pages are given to “Scale Insects” and twelve to “Plant 
Lice or Aphids.” There may also be some difference of opinion about the value of 
mentioning in a popular work a large number of forest bark beetles about which little 
or nothing is known, and which can be identified only by specialists. Some errors 
are bound to appear in a work of this sort (See Figure 131, duplicated in Figure 186) 
but these can be corrected in subsequent editions. The casual reader in looking over 
the volume and noting the references may get the idea that the book was written for 
the people of New York State, or that most of the work on shade tree insects has been 
done by its author. In my opinion the author’s greatest sin lies in giving so many 
references to his own publications and overlooking or omitting a number of rather 
important ones published elsewhere. For instance on page 53 at the end of the ac¬ 
count of the Bronze Birch Borer, Cornell Bulletin 234 by Slingerland might well be 
cited as it probably represents as much original work as either of those mentioned, 
and perhaps more. Citation of references more widely scattered would make the 
book more useful to readers over a wide geographical area. So far as is possible such 
citations should refer to publications making some contribution to a knowledge of 
the subject. Even in the systematic portion, such papers as Funkhouser’s on the 
treehoppers and Fulton’s on the tree crickets are omitted. 
In spite of the possible criticisms mentioned above, Dr. Felt’s book will prove a 
very useful volume and he should be congratulated by all entomologists on his accom¬ 
plishment. W. E. Britton

This is an extended distributional and descriptive account with numerous keys, of 
the bugs of Connecticut prepared under the direction of Dr. Britton in collaboration 
with a number of experts, mostly well known, in the different groups, namely, Messrs. 
Abbott, Bakei, Barber, Davis, DeLong, Funkhouser, Knight, Maxson, Osborn, 
Parshley, Stearns, Torre-Bueno, Van Duzee, Wilson, and Miss Patch. This publi¬ 
cation is one of a series, the first being a general account by Dr. Britton, the 
second a discussion of the Euplexoptera and Orthoptera of Connecticut by Mr. Wal¬ 
den, and the third, as voluminous as the fourth, an account of the Hymenoptera or
