eliore of Long Lslaiid for the purpose of locating the l)reeding grounds of mosquitoes 

 and suggesting methods for destroying them. Popular notes are given on the habits 

 and life history of mosquitoes by F. E. Lutz and C. B. Davenport. As the result of 

 the survey of this region, recommendations are made concerning the methods of 

 treatment of the various pools and bodies of stagnant water in which Culex and 

 Anojiheles were found to breed. It is believed by the authors that mosquitoes are 

 not carried by their own flight or by the action of the wind to any great distance 

 from their breeding ground. The north side of the island is thought, therefore, not 

 to become infested by mosquitoes from the southern shore. A report was made by 

 N. S. Shaler on the origin and present condition of the marshes and swamps of north- 

 ern Long Lsland. 



Notes on species of sand fly, W. R. Colledge {Proc. Roy. Soc. Qneeuxhtiul, 17 

 {1902), No. 1, jrp. 17-34, ph. 4)- — Detailed notes are given on the appearance, haljits, 

 and life history of a species of sand fly which is believed to be closely related to 

 Ceratopugnn albopundiis. The insect is described in its various stages and notes are 

 given on the difference in the habits of the 2 sexes. Aiijiarently only the females 

 attack man and domesticated animals. 



The horse bot fly, C. French and J. R. Weir {Jour. Dept. Ayr. Victoria, 1 {1903), 

 No. 7, pp. 693-697, pi. 1). — Notes are given on the habits and life history of Gastro- 

 philus crjiii. Mention is made of the usual remedies adopted in preventing or curing 

 infestation with the larvpe of this insect. 



The influence of feeding cane sugar and starch sirup on the composition 

 of honey, E. von Raumer [ZtscJir. Analyt. Client., 41 {1-'>0J), No. 0, j>p. oo-l-o'>0). — 

 Experiments were conducted by the author for the purpose of determining the extent 

 to which the ferment of the honey stomach of the bee acts as an inverting or hydro- 

 lyzing agent on cane sugar and dextrin. During the feeding experiments the total 

 amount of carljohydrates fed to the bees amounted to 1,336 gm., Avhile the total 

 amount of honey collected was 1,769.92 gm. Of the 456 gm. of cane sugar fed to the 

 bees only 16.9 gm. were found in the honey, while of the 532 gm. of dextrin which 

 was fed, 249.98 gm. were recovered in the honey. It is considered quite a remarkable 

 fact that so small a quantity of cane sugar remained uninverted, while in previous 

 feeding experiments a much larger percentage had jiassed over into the honey. 



The long-tongued bees (Apidae) of California, C. Fowler {California Sta. Rpt. 

 1S99-1901, jil. 2, p]i. 316-3S0). — The author gives brief notes on the occurrence and 

 distribution of the long-tongued bees of California. The notes are based largely on 

 material which was collected near Berkeley in 1S98. A number of new species were 

 found in this collection and have been described elsewhere. 



Studies on the organism of foul brood of bees, IT. Lambotte {Ann. Inst. Pas- 

 teur, 16 {1902), No. 9, pp. 694-707). — The author conducted a series of experiments 

 with material obtained from various infested colonies of bees in different localities. 

 As the result of extensive bacteriological study it is concluded that the so-called 

 Bacillus alvei is not a distinct species but is identical with B. mesenlericus vulgaris. 

 This organism is an exceedingly common species and forms spores in the manner 

 which had already been observed in the bodies of bee larva' affected with foul t)rood. 

 Inoculation experiments with healthy bees demonstrated that all the symi)toms of 

 foul brood (!ould be produced by pure cultures of B. mesentericus vulgaris. Upon 

 making a comparison of cultures of organisms obtained from bees affected witli foul 

 brood and of authentic cultures of B. mesentericus vulgaris, the 2 organisms were 

 found to agree in every respect. 



Silks of the Far East and French colonies; silkworms and related species, 

 H. J. DE CoRDEMOY {Lcs soies dans I' extreme Orient et dans Ics Colonies Fruncaises; les vers 

 a soie et leurs similaires. Paris: Agustin CJiallamel, 1902, pp. 112, pd. 1). — The author 

 presents a general account of the silk industry and discusses the present conditions 

 of this business in China, Japan, India, Indo-China, Madagascar, Western Africa,
