The fauna of British India, Hymenoptera, C. T. Bixoiiam (Londun: Tujilor & 

 Fntiiris, I'JO.y, vol. ,2, pji. .'70'-', pi. J,Ji(j'<. J(>}). — In this vohnne the autlior {)resents an 

 acconnt of the ants and cnckoo wasps. The anatomy of tliese insects is described in 

 detail, and l)rief notes are given on their food plants and distribntion. 



The destruction of ants by calcium carbid, Defgntaine {Agr. Prat. Pays Chauch, 

 2 {1903), No. 12, pp. 742-744)- — Three species of ants {Afta sexdens, CampovohiK rvfi- 

 pes, and Dinoponera grandis) were found to be injurious to cassava in certain i)lanta- 

 tions in South America. For the destruction of these ants the author recommends 

 the use of calcium carbid for the purjiose of producing acetylene gas in the burrows 

 of the ant colonies. The gas is then ignited and the ants are destroyed by the rapid 

 combustion and explosion of the gas. 



Destruction of white ants by means of sulphurous acid, P. Lesne {Jour. Agr. 

 Prat., n. ser., 6 {1903), No. 30, pp. 116, 117). — An apparatus devised for the produc- 

 tion of sulpliurous acid in combating various insect pests is briefly described. As a 

 result of his observations and experiments the author believes that this remedy fur- 

 nishes an excellent means of destroying ants, white ants, and other underground 

 insects. 



Foul brood and ants, Delepine {Jour. Agr. Prat., n. ser., 5 {1903), No. 22, pp.691, 

 692). — The author advises against the use of salicylic acid as a remedy for foul brood. 

 This remedy is not readily soluble in honey and exercises injurious effects upon the 

 bees. The remedy recommended by the author consists in the use of naphthaline, 

 which is hung in small sacks in various parts of the hives. 



In localities where ants prove to be a nuisance to bee raisers, from their habit of 

 crawling into the hives, the author recommends that hives be surrounded with troughs 

 of water for a limited period, so that the ants are unable to reach the entrance to the 

 hives and finally go elsewhere for their food. 



The A B C of bee culture, A. I. and E. R. Root {Medina, Ohio: A. I. Root Co., 

 1903, ]jp. 482, pis. 34, figs. 397). — A revised edition of this cyclopedia of bee culture, 

 including a discussion of recent experimental work in the management of Ijees, the 

 treatment of honey, together with a discussion of the diseases and enemies of bees, etc. 



The book of the honeybee, C. Harrison {London and New York: John Lane, 1903, 

 pp. 132, pis. 13, figs. 29). — The author presents an account of the arrangement of the 

 apiary, bee pasturage, appliances and apparatus in use in bee raising, the practical 

 operations involved in caring for bees and honey, and also an account of the diseases 

 and enemies of bees. The volume is well illustrated from photographs by J. C. Doug- 

 las, and contains such information as is required by the practical bee raiser. 



Apiculture {.Jour. Jamaica Agr. Soc, 7 {1903), No. 5,j)p. 184-187). — A brief discus- 

 sion of the production and composition of beeswax, together with notes on the adul- 

 teration and importation of this substance. On account of the abundance and cheap- 

 ness of Muscovado sugar in the West Indies it is suggested that this material might 

 profitably be fed to bees throughout the season for the purpose of furnishing them 

 material with which to make wax. 



Modern apiculture, A. Reinhold {Apicultura Moderna. Buenos Aires: Author, 

 1903, pp. 56, figs. 142). — A description of the beehives commonly used in North 

 America, together with other apparatus necessary for the successful management of 

 bees. 



The breeds of mulberry silkworm and their selection, D. Rowsinski {Selsk. 

 Khoz. i Lyesov., 209 {1903), May, pp. 375-413).— 'Notes are presented on the various 

 races of mulberry silkworms as raised in various countries and the comparative 

 merits of the different races for different purposes are shown in tabular form. The 

 general subject of silkworm culture is also discussed.
