554 EXPERIMENT STATION RECORD. 



serious factor in field-pea seed growing in the Paeitic Nortliwest. " Tlie dissem- 

 ination as hibernating puparia can be readily prevented by fumigation. As is 

 the case with the legume pod moth, it can not be exterminated because of the 

 native lupines. 



Some insect pests of maize, R. W. Jack {Rhodesia Agr. Jour., 9 {1912), No. 

 5, pp. 707-716, pis. If). — A brief account is given of the injury caused by some of 

 the more important insect enemies of corn in Rhodesia. 



[The cotton woraa and the Mexican cotton boll weevil], W. E. Hinds {Ala- 

 bama Col. 8ta. Rpt. 1911, pp. 22-2-'/). — Careful examinations made in the field 

 showed that the cotton worm actually decreased the Alabama cotton crop of 

 1911 by approximately 10 per cent. 



"The advance of the boll weevil began during the latter part of August, 

 1911, and continued until about the middle of November when frost killed the 

 cotton. The infestetl area then included all or part of 12 counties in Alabama, 

 the weevil line extending in a general southeasterly direction from near the 

 northeast of Pickens County to the middle of Escambia County. . . . The 

 area now infested by the weevil should produce about 10 per cent of the normal 

 Alabama crop." 



Relation between rotation systems and insect injury in the South, W. D. 

 Hunter {U. S. Drpt. Agr. Yearbook 1911, pp. 201-210). — This article points out 

 some of the general considerations that must be taken into account in connec- 

 tion with rotation practices which are coming to be generally followed in the 

 southern United States. E.xamples are given of simple means of reducing in- 

 sect injury by modifications of rotation systems. 



Pests and diseases, W. N. Sands {Imp. Dcpt. Agr. West Indies, Rpts. Bot. 

 Sta. [eta.], St. Vincent, 1910-11, pp. IJ,, 15). — A brief report is given of the 

 occurrence during the year of some of the more important insect enemies of 

 cotton. 



Parasites of insects attacking sugar cane, R. C. L. Perkins {Hawaiian 

 Sugar Planters' Sta. Ent. Bui. 10, pp. 5-27). — In this bulletin the author de- 

 scribes 19 now species and 1 new variety of chalcidoid parasites, nearly all of 

 which were breil from eggs of insects attacking cane in countries other than the 

 Hawaiian Islands. The American species were obtained by Koebele while in- 

 vestigating insects in the cane fields in Mexico during the winter months of 

 1908. All the rest were obtained by Muir in Fiji, China, and the Malay Islands. 

 Three genera, namely, Neotetrastichus, Jassidophthora, and Eomymar, are 

 characterized for the first time. 



Elm-leaf beetle and white-marked tussock moth, E. P. Felt {N. Y. State 

 Ed. Dept. Bill 51 1, 1912, pp. 35, pis. <S).— This bulletin, which is a revision of 

 New York State Museum Bulletin 109, previously noted (E. S. R., 19, p. 355), 

 presents popular accounts of these 2 shade-tree enemies. 



Forest entomology, A .T. Gillanders {Edinburgh and London, 1912, 2.ed.,pp. 

 XXIV+Jf^S, figs. 35.'i). — In this second edition (E. S. R., 20, p. 652) the chap- 

 ters have been rearranged more in accordance with the sequence of entomolog- 

 ical classification. 



Insect damage to mine props and methods of preventing the injury, T. E. 

 Snyder {U. S. Dept. Agr., Bur. Ent. Cire. 156. pp. 4).— This circular, based 

 on special investigations in cooperation with mining companies, gives prelimi- 

 nary information on the principal types of insect injury and shows how a large 

 percentage of injury can be prevented. 



" By barking and seasoning mine timbers, insect injury before placement will 

 not only be prevented, but injury by termites after placement will also be 

 delayed or under some conditions even prevented and the length of life of the
