BOOK NOTICE. 



Guide to the Insects of Connecticut. — Prepared under the direction 

 of William Everett Britton, Ph.D., State Entomologist and Entomolo- 

 gist of the Connecticut Agricultural Experiment Station. Bulletin i6, 

 Connecticut Geological and Natural History Survey. Part I, General 

 Introduction, by \V. E. Britton. Part II, The Euplexoptera and 

 Orthoptera of Connecticut, by Benjamin Hovey Walden, B. Agr., 

 Assistant in Entomology, Connecticut Agricultural Experiment Station. 



This is the first of a series of papers on the insects of Connecticut, in 

 which the authors "expect that the entire subject may ultimately be treated." 



Part I, comprising the first thirty-eight pages of the report, is a very 

 brief introduction to the study of insects, adapted to the non-entomolo- 

 gical reader. Besides a general account of insects, their structure, habits, 

 distribution, economic status, etc., a short bibliography is given of the 

 more important works relating to North American Entomology, and a 

 simple but practical key to the various orders. The arrangement of these 

 in the list which follows is that of Comstock, modified in the Neuropteioid 

 groups by Banks. 



A (ew statements are made that are not strictly accurate, e.g., that 

 tracheal gills persist in the adults of some dragonflies and that the may- 

 flies, which form a very large item in the food-supply of many of our 

 food-fishes, are not important economically. 



Part II is an excellent guide to the Euplexoptera and Orthoptera of 

 Connecticut, and contains useful analytical tables and descriptions of the 

 various families, genera and species of these orders known to inhabit 

 Connecticut or adjacent territory. 102 species are described, of which 

 92 are definitely recorded from wi,thin the limits of the State. The 

 nomenclature followed is that which has been in general use for a number 

 of years, and we are glad that the author has not chosen to adopt any of 

 the recent changes through which old and familiar generic names, by 

 a rigid adherence to the laws of priority, have been transferred to other 

 genera, the result being a succession of confusing alterations involving not 

 only generic but sub family and even family names as well. 



The text-figures, of which there are sixty-six, are well chosen, and 

 are, for the most part, copied from the works of Scudder and Morse. 

 There are also eleven half-tone plates from photographs, the first five 

 illustrating Part I and showing typical examples of the various orders and 

 the early stages of a few forms, the remaining six illustrating fifty species 

 of Connecticut Orthoptera and Euplexoptera.
