" The saw-toothed {^rain beetles, Silvanus surmamensis, were always abun- 

 dant. The confused tlour beetles, Tribolium confusum, were coinmoii in all 

 shipments, and T. ferrugiiieum was also often quite common. The lesser grain 

 borer (Rhizopertha dominica) was always quite abundaut and apparently very 

 destructive. The flat grain beetle {Lwrnoplilccus. miimtiin) was common in 

 all lots. The cadelle and a few other beetles were more or less common. 

 MesaporuH calandrcv, the cosmopolitan parasite of grain weevils, was common 

 on nearly all lots of Australian wheat examined, and it was exceedingly abun- 

 dant in some of the lots." 



A suggestion of a possible control of pea and bean weevils, R. E. Camp- 

 bell {Jour. Econ. Ent., 12 (1919), No. 4, PP- 284-288). — In work carried on in 

 California the author found the percentage of infestation of broad or horse 

 beans by the broad bean weevil (^Bruchus^ Laria rufiiiiaua) to be very much 

 less in crops from seed planted late in the season than from crops from seed 

 planted early. While the first eggs are laid soon after the middle of March 

 and a few may be laid as late as the middle of May, the most extensive deposi- 

 tion occurs during the month of April. 



Data presented in tabular form show a maximum of 50 and 63 per cent of 

 weevil infestation, and averages of 14.5 per cent for the 1916 and 1917 crops, 

 when the seed was planted both early and late, as contrasted with a maximum 

 of only 17.2 per cent and an average of 2.92 per cent of weevil infestation for 

 the 1918 crop, when no seed v,'as planted until after March 1. Many samples 

 of the 1918 crop were entirely free from infestation, particularly those from 

 seed planted in April and May.

 Bui. 85 {1919), pp. 2-8. ftgf!. 2).— A popular account. 



The European elm sawfly leaf miner, R. N. Chrystal {Agr. Gaz. Canada, 6 

 {1919), No. 8, pp. 72-'>-728, fig. 1). — This sawfly leaf miner {Kaliosysphinga 

 iilmi), first recorded in America by Felt in 1S98 as unusually destructive at 

 Albany and Troy, N. Y., was first discovered in Canada at Kingston, Ont., in 

 July, 1915. Recent investigations have shown the species to occur in the city 

 of Kingston iu a few localities, mainly on the Camperdown variety of Scotch 

 elm, the American elm not being attacked. 



A series of experiments by Hutchings with an allied species, the alder sawfly 

 leaf miner {K. dohrnii), at the Central Experimental Farm, Ottawa, showed 

 kerosene emulsion, 1 part of stock solution to 7 parts of water, to be effective 

 when xised at the time the larval mines were just commencing. This indicates 

 that this remedy would also be effective against K. ulmi. 



An account of its life history by Slingerland in 1905 has been noted (E. S. R., 

 17, p. 680), as has been an account by Herrick in 1913 on its control (E. S. R., 

 29, p. 5.56).
