numerous of the small mammals, and their food habits, as well as those of 

 the great family to which they belong, should be better known." 



" Like many other small rodents, they are nocturnal and so shy that their 

 presence in large numbers is readily overlooked. They inhabit widely differing 

 faunal areas, but everywhere burrow in the gi-ound under bushes, trees, rocks, 

 logs, or other shelter, and generally are most numerous in such cover along the 

 borders of fields. The entrances to the burrows are inconspicuous, opening, as 

 they commonly do, under thick beds of leaves, logs, or rocks; small quantities 

 of earth are thrown out about them from time to time, but not usually forming 

 a definite mound. These pocket mice reach their greatest abundance in semi- 

 arid, partially wooded regions, both plains and mountain slopes being well popu- 

 lated with them. Some species of Heteromys, however, inhabit humid heavily 

 forested areas apparently throughout middle America. From 3 to 5 young are 

 produced at a birth, 4 being the usual number. While the young seem more 

 numerous in spring and early summer than at other times, it is evident that the 

 animals breed throughout the year." 



Thirteen species and 1 subspecies of Heteromys and 10 species and 18 sub- 

 species of Liomys are recognized by the author, of which 1 species (temporalis) 

 of Heteromys and 1 species (guerrerensis) and a subsjiecies (irroratus pretiosus) 

 of Liomys. all 3 from Mexico, are characterized for the first time. 



Distribution of the American egrets, W. W. Cooke (U. S. Dept. Agr., Bur. 

 Biol. Survey Circ. SJ/, pp. 5, maps 2). — A brief discussion is given of the 2 com- 

 mon white herons or egrets (Herodias egretta and Egretta candidissima) , to- 

 gether with maps which show their original range. 



It is stated that the demand of the millinery trade for plumes has caused such 

 a wholesale slaughter of these 2 species that they are almost extinct over large 

 areas where they were formerly common. Fortunately in the case of both of 

 these species breeding colonies still remain in the southern part of the United 

 States to serve as centers of distribution to the districts formerly included in 

 the range. 



Eighth annual report of the state entomologist of Montana, R. A. Coolet 

 (Montana 8ta. Bui. 82, pp. 131-1^). — This report consists of a brief discussion 

 of the work of the entomological department. It calls attention to the farmers' 

 and fruit growers' need for more information, mentions the need of a movable 

 exhibit, and discusses the relation of the state entomologist's office to other 

 organizations in the State, the prices of insecticides in Montana, the necessity 

 for a Montana law regarding adulterated insecticides, etc. 



Department of entomology, S. B. Doten (Nevada Sta. Bui. 181, PP- -iO-^S). — 

 This report consists of brief accounts of an open-air insectary which has given 

 very successful results, photographic records, and the more important insects 

 of the year, namely, San Jose scale, oyster shell bark louse, European elm scale, 

 codling moth, ants, cutworms, and Mediterranean flour moth. It is stated that 

 the alfalfa leaf weevil had not been found in Nevada at the time of writing. 



Beport of the entomologist, R. I. Smith (North Carolina Sta. Rpt. 1910, pp. 

 31-83). — This report consists largely of brief statements of the occurrence dur- 

 ing the year of the lesser corn stalk borer (Elasmopalpns lignosellus), catalpa 

 sphinx (Ceratomia catalpa), the sugar-cane borer or larger corn stalk borer, 

 woolly apple aphis, striped flea beetle (Phyllotreta vittata), cross-striped cab- 

 bage worm (Evergestis rimosaUs), Hessian fly, and strawberry weevil. 



Report on economic entomology and zoology, F. V. Theobald (Jour. South- 

 east Agr. Col. Wye, 1910, No. 19, pp. 83-211, pis. 56, figs. 8).— This is the author's 

 annual report on the occurrence of injurious insects, etc., in England. They are 

 considered under the headings of animals injurious to man's domesticated
