as hosts for the fever tick. Brief accounts are given of the various mammals 

 of importance and methods for tlieir destruction. An annotated list of the 

 mammals found in and near the Bitterroot Valley, Mont., together vpith repro- 

 duced photographs of many of the species is presented by C. Birdseye (pp. 

 9-24 ) . 



Three important wild duck foods, W. L. McAtee ( U. S. Dept. Agr., Bur. Biol. 

 Survey Circ. 81, pp. 19, figs. 19). — The vegetable food of wild ducks includes a 

 hirge variety of plants of which wild rice, wild celery, and pondweeds have 

 been found of especial importance. In the case of 16 of the more important 

 species of game ducks, the stomachs of which have been examined, these 3 

 foods collectively composed 25.31 per cent of the total food. Their value as 

 duck food is discussed, together with descriptions of each, their distribution, 

 transplantation, and enemies. It is stated that all 3 can be propagated in suit- 

 able waters anywhere in the United States. 



Directory of officials and organizations concerned with the protection of 

 birds and game, 1911, T. S. Palmku (17. 8. Dept. Agr., Bur. Biol, Survey Circ. 

 83, pp. 16). — This, the twelfth annual directory of officials and organizations 

 concerned with the protection of birds and game in the United States and 

 Canada, is revised to July 15, 1911. The arrangement is the same as that of 

 previous issues (E. S. R., 23, p. 554). 



Index-catalogue of medical and veterinary zoology, C. W. Stiles and 

 A. Hassall {U. S. Dept. Agr., Bur. Anim. Indus. Bui. 39, pt. 35, pp. IV +2655- 

 2703). — This part lists the literature by autliors from Y to Zypkin. 



Report of the entomologist, W. V. Towee {Porto Rico Sta. Rpt. 1910, pp. 

 31-3'/). — This report consists of brief notes on guava, coffee, and citrus insects, 

 and bees and bee keeping in Porto Rico, and on insect pests in Cuba. 



The guava fruit fly, which infests practically all the fruit, and 2 beetles the 

 larvae of which feed on the fruit, are said to be the most destructive of the 

 insects attacking the guava. An ant, which lives in the coffee shade trees and 

 occasionally in the coffee itself, is the source of serious injury to coffee. Suc- 

 cessful results are reported to have been obtained from the fumigation of citrus 

 trees. At the present time there seems to be a bright futui'e for the bee industry 

 in Porto Rico as there are no diseases, and where Italian bees are used bee 

 moths are not troublesome. A law intended to prevent the introduction of bee 

 diseases was passed by the last session of the legislature. 



A trip to Cuba was made in June and July, 1910, with a view to studying the 

 sugar cane insects of the island and obtaining parasites of the Lachnostema 

 beetle. However but 2 specimens of this beetle were found. Many of the 

 planters recognized it from descriptions given and all stated that its flight 

 occurred during March, April, and May, which is the same time that its flight 

 takes place in the district of Mayaguez, Porto Rico. The flight of this beetle 

 was found to be the same in all parts of Cuba visited, namely, Santiago de Cuba, 

 Habana, Ceballos. Cienfuegos, and Manzanilla. The sugar cane insects of Cuba 

 are said to be similar to those of Porto Rico. 



The insect pest of the Mokameh Tal lands, E. J. Woodhouse and H. L. Dutt 

 {Dept. Agr. Bengal, Quart. Jour., 4 {1911), No. Jf, pp. 198-213, maps 2). — The 

 cutworm Agrotis ypsilon has been found to do serious damage in the Tal lands 

 in the vicinity of Mokameh. It produces 2 broods a year on these lands, the 

 second brood being responsible for the damage. Prodenia Uttoralis appeared 

 as an accidental pest in 1910. 



Annual report of the entomologist for the year 1909-10, T. J. Anderson 

 {Dept. Agr. Brit. East Africa Ann. Rpt. 1909-10, pp. lJi7-162).— Brief accounts 

 are presented in this report of the insects injurious to man and animals, timber, 

 the coconut palm, and orchard and garden crops.
