A review of the American moles, H. H. T. Jackson ( U. S. Dept. Agr., Bur. 

 Biol. Survey, North American Fauna No. 38 (1915), pp. 100, pis. 6, figs. 27). — 

 It is pointed out that moles are widely distributed throughout a large part of 

 North America and are very numerous in many places. While they have in 

 some localities proved injurious to agriculture, they are generally beneficial 

 through the destruction of insects, which form much of their food. 



The present paper is intended to serve as a basis for investigations of their 

 economic status, careful investigations of which are said to be under way. 

 The present work, which is largely systematic, recognizes five genera, namely, 

 Scalopus, represented by three species with eleven varieties ; Scapanus by four 

 species with nine varieties ; Neiirotrichus by one species with two varieties ; 

 and Parascalops and Condylura by one species each. Keys are given for the 

 separation of the genera, species, and subspecies. The accounts of the species 

 and subspecies include their synonymy, type locality, geographic range, general 

 characters, etc., together with a list of the number and locality from which 

 specimens were obtained. 



Distribution and migration of North American gulls and their allies, 

 W. W. CooKE {U. S. Dept. Agr. Bui. 292 (1915), pp. 10, figs. 51).— This bulletin 

 presents information regarding the ranges of the .several species of gulls, in- 

 cluding skuas and jiegers, especially the breeding ranges and migrations, and 

 includes data for use for legislative reference to serve as a basis for legal pro- 

 tection for the species by States in which they are found. Tliey are repre- 

 sented in the United States by 22 .species or subspecies and are important as 

 scavengers, enemies of mice, and of insects. 



Report of the entomologist, T. J. Headij:e (New Jersey Stas, Rpt. 1914, PP- 

 339-399). — In the first part of this report the author presents a general out- 

 line of the work including a classified tabular statement of the name, date, and 

 locality from which insects were received. Notes are next presented on the 

 in.sects of the year, the more important of which are the grape leaf-hopper, pear 

 psylla, plant lice, San Jos6 scale, oyster shell scale, false apple red bug (Lygidea 

 mendajr), potato flea-beetle (Epitrix cucumcri<>), rose chafer, May beetle, straw- 

 berry weevil, white pine weevil (Pissodcs strobi), hickory bark beetle H^rolytus 

 qnadrispivosus) , an unusual greenhouse insect, viz, Euractophagus graph ipicrus, 

 army worm, apple tree tent caterpillar. Florida fern caterpillar (Eriopus flori- 

 densis), Argentine ant (Iridomyrmcx hiimilis), etc. 



Experiments by C. S. Beckwith in combining nicotin preparations with spray- 

 ing mixtures led to the conclusion that black leaf 40 and " Nickotiana " can be 

 mixed with the common spray mixtures without a serious precipitate forming 

 and without any apparent detriment to the nicotin. 



A report on Potato Spraying and Dusting Experiments for the year 1914, by 

 A. E. Cameron (pp. 361-381) presents data previously noted (E. S. R., 33, pp. 

 336, 636), and a report on Fly Control on the College Farm, by C. H. Ricliard- 

 son (pp. 382-399) is noted on page 160. 



Outdoor wintering of bees, E. F. Phillips and G. S. Demtjth (U. S. Dept. 

 Agr., Farmers' Bui. 695 (1915), pp. 12). — This popular account of the care which 

 .should be given bees when wintered outside is based in part upon investigations 

 previously noted (E. S. R., 31, p. 254). 



Grasshoppers and their control on sugar beets and truck crops. F. P. 

 JIilliken (U. S. Dept. Agr., Farmers' Bui. 691 (1915), pp. 16. figs, ii).— This 

 bulletin deals with the four species of grasshoppers which were responsible for 

 most of the injury to Kansas truck crops during 1911. 1912. and 1913. namely, 

 the differential grasshopper (^fclanoplu/i ditfrrentialis), the two-lined gra.ss- 

 hopper (J/, hivittatus), the lesser migratory grasshopper (J/, atlanis). and the
