The Engelmanu spruce beetle {D. engelmanni) attacks the Engelmann spnice 

 and probably other spruces from central Idaho southward to the mountams of 

 southern New Mexico and the white spruce in the Black Hills of South Dakota. 

 The methods of controlling this beetle are essentially the same as for the 

 eastern spruce beetle. The Alaska spruce beetle (D. horeaUs) is but little 

 known. The Sitka spruce beetle (D. obesus) attacks the Sitka spruce from 

 Newport, Oreg., northward along the coast of Alaska, probably following the 

 distribution of the tree in which it lives. The redwinged pine beetle {D. 

 rufipennis) attacks felled white pine in northwestern Michigan. The lodge- 

 pole pine beetle (D. murrayanxe) attacks Ihe lodgepole pine in southern Wyo- 

 ming and occurs northward to Alberta, B. C. 



The Allegheny spruce beetle {D. punctatus) has been collected in West Vir- 

 ginia on a red spruce tree felled the previous winter. But little is known of its 

 habits. The European spruce beetle (D. micans) attacks spruce, pine, fir, and 

 larch from central to northern Europe and in Denmark, Russia, and eastern 

 Siberia. The black turpentine beetle (D. terebrans) attacks pine and spruce 

 from Long Island, N. Y., southward to Florida and westward to Texas and 

 West Virginia, but it is more common in the South Atlantic and Gulf States. 

 Methods of control should be based on the prevention of the primary injury 

 by preventing the undue multiplication of the beetle, or by furnishing a con- 

 tinuous supply of more attractive breeding places, as iu the case of continued 

 lumbering operations. The red turpentine beetle (D. valens) attacks pine and 

 spruce in eastern United States and Canada, northward from the mountains of 

 North Carolina, westward to the Pacific coast, and southward from British 

 Columbia into Mexico. The methods of control for this species are much simi- 

 lar to those for the black turpentine beetle. 



A bibliography of the economic literature is appended to the account. 



New South American Hym^enoptera, C. Schrottky (An. Soc. Clent. Argen- 

 tina, 67 {1909), No. 5, pp. 209-228). — Of the numerous new species here de- 

 scribed from Brazil, Uruguay, Paraguay, and Argentina, several from Paraguay 

 represent the parasitic families. 



Nutritive exchang'es in the bees during the 4 seasons, Maeie Paehon (Ann. 

 ^'c/. Nat. ZooJ., 9. srr., 9 {1909), No. 1, pp. 1-57, fif/s. 23; abs. in Naturiv. Rund- 

 schau, 2'f {1909), No. 35, pp. .'i'i3--'i'i5) . — A physiological study of the bees. 



The Ichneumons of Great Britain, C. Morley {Plymouth, 1907, vol. 2, pp. 

 XVI+351, pi. 1, fff/s. 22; 1908, vol. 3, pp. XVI+328, pi. 1, figs. l-'i).—A de- 

 scriptive account of the families, genera, and species indigenous to the British 

 Islands, together with notes as to the classification, localities, habitats, 

 hosts, etc. 



In the first volume, previously noted (E. S. R., 10, p. 279), the Ichneumoninaj 

 are considered ; in the second volume the Cryptinte are taken up, 41 genera and 

 317 species being recorded, of which 2 genera and 7 species are new to science; 

 and in the third volume the Pimplinre are considered, 39 genera and 211 species 

 being recorded, of which 1 genus and 8 species are new to science. 



The oviposition of Aphelinus mytilaspidis, P. Marchal {Compt. Rend. 

 Acad. Scl. [Paris], 1J,S {1909), No. 18, pp. 1223-1225).— A report of the author's 

 observations on the oviposition of this parasite in Aspidiotus ostrewformis. It 

 is considered probable that some of the scales are punctured simply for food. 



Report of the entomologist, J. B. Smith {New Jersey 8tas. Rpt. 1908, pp. 

 305-378, pi. 1, figs. 8). — During the year under report the elm-leaf beetle ap- 

 peared in large numbers, resulting in the largest brood that the author has 

 known. Attempts to establish the parasite Tetrastichus xanthomelamw, im- 

 ported from France as previously noted (E. S. R., 20, p. 957), apparently failed 

 in New Jersey.
