up, are followed by an account of the breeding and distribution of the tachinid 

 in Hawaii. 



In a discussion of the benefits derived from the introduction of the tachinid, 

 it is shown that the reduction in the borers has resulted in a greater yield of 

 good cane per acre, and a further increase in the yield of sugar per acre 

 through the improvement of the quality of the juice. The number of tons of 

 cane required to make a ton of sugar was reduced in successive years from 

 31.04 tons in 1911 to 9.37 tons in 1914. In many places it is now difficult to 

 find injury by the borer where formerly much cane was injured. While the 

 tachinids are difficult to find, it has been shown that they can locate borers 

 even where scarce and are able to keep up their existence. 



A list of 40 references to R. obscura is included. 



Seven appendixes comprise papers by F. Muir, namely, Report on Investiga- 

 tions in South China (pp. 52-57), Notes on the Sugar-cane Hoppers and Borers 

 in the Malay States and Java (pp. 58-64), Entomological Work in Borneo 

 (pp. 65-73), and Report on the Search for the Sugar-cane Borer in the Malay 

 Archipelago (pp. 74-79)*; Report on the Sugar-cane Borer in the Moluccas 

 (pp. 80-87), previously noted from another source (E. S. R., 22, p. 362) ; 

 Concluding Report on Travels in the Malay Archipelago in Search of Parasites 

 for the Cane Borer (pp. 88-93), and Report on Second Trip to British New 

 Guinea to obtain a Tachinid Fly Parasitic on the Sugar-cane Beetle Borer 

 (pp. 94-102 )^ An account by lUingworth of the introduction of C. spheno- 

 phori from Hawaii into Fiji has been noted (E, S. R., 32, p. 350). 



Orchard bark beetles and pinhole borers, and how to control them, F. E. 

 Brooks (U. S. Dept. Agr., Farmers' Bui. 763 {1916), pp. 15, figs. iS).— Brief 

 accounts are given of the fruit-tree bark beetle {Scolytus rugulosus), the peach- 

 tree bark beetle (Phlwotribus Uminaris), the apple wood-stainer (Monarthrum 

 mali), and the pear-blight beetle {Anisandrus pyri), and the manner of com- 

 bating them. 



The determination of the abdominal and thoracic areas of the cerambycid 

 larvae as based on a study of the muscles, F, C. Craighead (Proc. Ent. Soc. 

 Wash., 18 {1916), No. 3, pp. 129-U6, figs. 4). 



Scientific queen rearing, C. W. Quinn {Science, n. ser., 43 {1916), No. 1122, 

 pp. 939, 94I). — Following a brief reference to the work by Newell previously 

 noted (E. S. R., 33, p. 159), the author reports the results of crossing experi- 

 ments with golden Italian and gray Caucasian bees. 



The Isle of Wight bee disease, A. D. Imms {Jour. Roy. Agr. Soc. England, 

 75 {1914), PP- 62-70, fig. 1). — A popular summary of knowledge of this disease 

 of bees, due to Nosema apis, with remedial and preventive measures. A list of 

 nine references to the literature is included. 



A new bee of the genus Dianthidium, S. A. Rohwer {Proc. Ent. Soc. Wash., 

 18 {1916), No. 3, pp. 192, 193). 



Notes on the biology of Paraphelinus speciosissimus, W. R. McConnell 

 {Ann. Ent. Soc. Amer., 9 {1916), No. 1, pp. 97-102).— This is a report of obser- 

 vations of P. speciosissimus at Hagerstown, Md., where it has been reared from 

 Hessian fly puparia. 



The species was described in 1911 from a single specimen taken on a granary 

 window at Urbana, 111. It has been reared by the author from puparia in 

 wheat stubble collected at six localities in central Pennsylvania, but has not 

 been found to occur at other points in Pennsylvania, or in Maryland, Virginia, 

 and West Virginia. This species is a primary multiple parasite of the Hessian
