about 4 years, and the presence of the fungus in Great Britain has not hitherto ])een 

 recorded. The fungus is descril)ed and the results of successful inoculation experi- 

 ments are rei)orted. 



The treatment of fungus pests, A. Howard {Imp. Dept. Agr. Wed Indies, 

 Pamphlet Xo. 17, lOOJ, pp. 43, figs. 5). — Brief popular descriptions are given of a 

 number of the more common plant diseases known to occur within the West Indies, 

 and suggestions made oi measures to be adopted to prevent their spread. 



Annual review of the literature relating to plant diseases, 1901, M. Holl- 

 KUN<; (JdJirexhericIit I'lhcr die Xenenuigen. and. Leidimgen anf dein (leliiete der Pflanzen- 

 krdnkhelteii. Berlin, 1903, pp. VIII^SOo). — A review is given showing the progress 

 that has been made in protecting useful plants against fungus, insect, and other 

 depredations, and means for preventing loss from these agencies. The literature, 

 which is quite voluminous, is for the most part grouped as in the previous reports 

 (E. S. R., 12, p.. 658; 14, p. 62), the classification being essentially the same. In the 

 present number the author gives a short summary of the present status of knowledge 

 regarding the various topics discussed, followed by abstracts of the more important 

 contributions relating to them and a list of related papers, some of which are briefly 

 abstracted. The new grouping of all the references to a single topic will be found a 

 decided advance over the former arrangement, in which the important al)stracts were 

 separated from the briefer ones and those which w'ere only mentioned by title. 



ENTOMOLOGY. 



Proceeding's of the fifteenth annual meeting of the Association of Economic 

 Entomologists ( U. S. Dept. Agr., Division of Entomology Bnl. 40, n. ser., pp. 124, 

 1)1 !<. J, figx. G) . — An account of this meeting, held in Washington, D. C, December 26 

 and 27, 1902, has been previously given (E. S. R., 14, pp. 535-538). In addition 

 to the papers there noted, the following are included in the proceedings: 



The lime-sulphur-sidt mixture in Connecticut, W. E. BriUon (p. 38). — This mixture 

 proved to be as effective as any other remedy in the destruction of scale insects and 

 did not injure trees in any case. It was also used in several large orchards with 

 satisfactory results. 



DevelopmentandJiibernnfionnfmo.'tquifoe.^, II. A. Morganand.L W. Dnpreeipp. 88-92). — 

 From these studies it is concluded that the 24 species of mosquitoes upon which notes 

 were made can breed successfully in small pools. Most of the mosquitoes deposit 

 their eggs singly uj^on the surface of the water. Water is believed not to be essential 

 to the pupee of some species so long as moist soil is accessible. The only 2 stages in 

 which the mosquitoes were found hibernating were the egg and adult conditions. 



Some insect inhabitants of the stems of Elymus canadensis, F. M. }yehster (pp. 92, 93). — 

 This species was much more extensively infested by insects, especially those of the 

 genus Isosoma, than other related species of the same genus. 



Some insect note., of the year, F. M. Webster (pp. 93-96). — A brief discussion of the 

 Hessian fly, apple a^Yns,, Schizocerus zabriskei, Ceratomia catcdpee, etc. It was observed 

 that the red rust was more prevalent on wheat which had. been attacked by the 

 Hessian fly than on that which was not thus affected. 



MoKquitocides, J. B. Smith (pp. 96-108). — Experiments were made to determine 

 whether any insecticide substances could be mixed with water so as to prevent the 

 development of mosquitoes. In these experiments the author tested permanganate 

 of po<:ash, INIosquitocide, salt, naphthaline, lime, copperas, crude petroleum, Phinotas 

 oil, Phinotas disinfectant (5 per cent and 20 per cent), Phinotas Mark G, soluble 

 blast furnace oil, Chloro-naphthalum, Puraline, Tarola, Milky Disinfectant, cretol, 

 soluble creosdte, Cresol (100 per cent), Phenol-septol, Synol Liquid, etc. These ex- 

 periments indicate that there are several preparations which may serve as disinfect-
