ENTOMOLOGY. 281 



Experiments to test the value of Bug Death as compared with Paris green 

 and Bordeaux and Paris green on potatoes, R. Robertson (Canada Expt. 

 Farms l!j</.<. 190S, pp. 296,297). — The experiments reported with these insecticides 

 indicate that many of the treatments, are effective in destroying potato beetles, hut 

 that Paris green is exceedingly cheap as compared with treatment by means of Bug 

 Death. 



Chemistry of insecticides and fungicides, F. T. Shutt ( Canada Expt. Farms 

 Rpts. 190-3, pp. 152-155). — Analyses are presented of Kno Bug, Bug Finish, and for- 

 malin. Insecticidal properties of Kno Bug and Bug Finish were found to be fairly 

 satisfactory, hut the claims made concerning the fertilizing action < if these preparatii >ns 

 are quite unfounded. The products also cost much more than homemade insecti- 

 cides. According to analyses made by the author the amount of formaldehyde by 

 weight in commercial formalin varies from 36 to 37 per cent. An analysis was made 

 of Owens' compound for the protection of trees against insect and fungus ravages. 

 This preparation was found to consist largely of sulphur to which from 5 to 10 per 

 cent of charcoal had been added. 



Spraying calender, L. R. Taft and C. D. Smith (Michigan Sta. Sj, t <-. Bui. 26, 

 folio \. — Recommendations are made in a tahular form of insecticides and fungicides 

 to be applied in controlling the more important insect and fungus diseases of fruits 

 and garden vegetables. Formulas are also presented for the preparation of thc-t- 

 sprays. 



Supplementary notes on the tsetse flies, E. E. Austen (British Med. Jour., 

 1904, No. 2281, pp. 658-662, fig. 1). — Descriptive, biological, and economic notes 

 are presented on several species of the genus Glossina. This article is intended t.i 

 contain information supplementary to the author's monograph of tsetse flies. The 

 habits of these insects in their various stages are described in considerable detail, 

 especially in relation to their agency in the transmission of diseases. An analytical 

 table is presented for the determination of the species. 



Malaria and mosquitoes, G. McCarthy (Bui. North Carolina State Bd. Agr., 

 25 (1904), No. 6, pp. 66-76, figs. 10). — The life cycle of the malarial parasite is briefly 

 outlined and notes are given on the habits and life history of a number of mosquitoes 

 which commonly occur in North Carolina, with especial reference to the species con- 

 cerned in transmitting malaria. Approved methods of destroying mosquitoes are 

 recommended. 



The honeybee, T. W. Cowan (London: Houlston & Sons, 1904, 2. ed., pp. XII-\- 

 220, pi. l,figs. 73). — This volume has been revised so as to include some of the more 

 recent work on the habits and biology of the honeybee. The volume is occupied 

 chiefly with a scientific and entomological discussion of this insect rather than with 

 its economic importance. Especial chapters are devoted to the gross and microscop- 

 ical anatomy of various organs of bees, and an account is presented of drones, queens, 

 parthenogenesis, metamorphosis, and comb construction. 



Bees, S. A. Bedford (Canada Expt. Farms Rpts. 1903, p. 338). — Some losses in 

 bees are reported as a result of inadequate stores during the winter. The best suc- 

 cess was had in shipping bees in the Langstroth hives. Sweet clover is considered 

 as a very good and productive bee plant. 



Chemistry of bee keeping, F. T. Shitt ( Canada Expt. Farms Rpts. 1903, pp. 155- 

 158). — Experiments carried on during the year under report showed that extracted 

 honey exposed to an atmosphere saturated with moisture soon exhibited signs of 

 deterioration, becoming thin and rapidly fermenting. Honey in the comb was simi- 

 larly affected, but resisted the effects of moisture for a much longer time. It is rec- 

 ommended on the basis of these experiments that honey be stored in a warm, dry 

 atmosphere. Notes are given on the analysts of beeswax, some of which was found 

 to be greatly adulterated with paraffin.
