"Dispersal Routes" are very well presented and the effect of the disap- 

 pearance of the one-time extensive coastal sandy plain on the range of 

 certain Orthoptera, which now have discontinuous or localized distribu- 

 tions, is considered. The importance of the influx of campestrian sand- 

 loving species from the southwest is emphasized, and a comprehensive 

 summary of locust habitats or societies is given, the groups being those 

 already used by the author. Morse's attitude toward certain of the 

 present day ecological work is a just one and his footnote on page 260 is 

 well worth reading by those interested. 



In the section on "Wingless and Vestigial-winged Orthoptera" the 

 author reafifirms his previously expressed hypothesis on the correlation of 

 long and short-winged locusts in general with definite types of habitat. 



In his table of the species recorded from New England the author gives 

 132 species as recorded from New England, 104 of these native and 28 

 introduced purposely or accidentally. 



In the discussions of locust injuries and other matter of economic im- 

 portance the fact is emphasized that in New England severe outbreaks 

 usually have been local in area and of comparatively limited extent, 

 although, as the context shows, occasionally of great severity. Methods 

 of control and natural enemies are discussed and it is shown that such 

 enemies are numerous and varied, ranging from fungus to the lowly farm- 

 yard cat. There is a most useful section on "Methods of Collecting and 

 Preservation," which gives a summary of the procedure followed by the 

 author, and also draws upon the experience and practice of other workers. 



The division of the work treating systematically of the New England 

 Orthoptera follows in general the following method: discussion of each 

 family, general character, summary of development, food, general dis- 

 tribution, key to species; under species, leading references, brief descrip- 

 tion, measurements, habits and life period, distributional notes and 

 records in New England, and generally one or more figures. Under 

 families such as the Blattidae and Gryllidae established exotic species 

 and adventive species are each properly treated separately from native 

 forms. English names are given in all cases for species, the majority 

 newly coined; the results are not always happy, as for example the " Broad- 

 shouldered Angulate Pygmy Locust," although as a whole the names 

 have been more carefully selected than is usually the case. The author 

 avoids initiating nomenclatoral novelties, which is greatly to be com- 

 mended, as a work intended as a manual for the student is no place for 

 the airing of innovations or controversial matter, but should, instead, be 

 founded on previously published conclusions. 



We find the earwig Euborellia annulipes reported as introduced in New 

 England for the first time. Brief analyses of the variant color patterns 

 of the species of Orphiilella and of Chorthippus curtipennis are given, 

 and these are particularly timely and useful. The word pictures of habi-
