Twelfth annual report of the state entomologist of Montana, II. A. 

 CooLKY (Montana Sla. Hal. 102 {WUi). i>i>- J91-208. fit/. /).— The author pre- 

 sents brief notes on the occurrence of the inoic iinportanl insect i)ests during 

 1914. 



[Desti-uctive insects in 1913J (lid. Ayr. and Fi-Hliciian [London'^, Ann. Rpt. 

 //o/7. liidnch, I'JI.i-I.'i. ijjj. '>'>-77). — Tlie occurrence of and worlc with the large 

 larch sawtly ( f.m/annentatitx erlchftonii) , the small ermine moths (Ilypo- 

 nonientu spp. ), and diseases of bees are discussed at some length. 



Entomological notes {Vijitnis Jour. \o. S-l (/.9i.'/). pp. SOoSOl). — ^The notes 

 here presented relate to injury to the grape by JEolothrip>^ vitis; the steps to 

 be taken in the destruction of Cccidomyia ceratonice* which, causes stunted 

 fructification of the carob, pepi)er, and caper; and the damage done by the 

 cotton bolhvorm,*the loss in some cases amounting to 50 j)er cent of the yield. 

 A. vitis causes a characteristic scar or spot ui)on the grai>e and also produces 

 a curling of the tender shoots and a stunted development of the growth of 

 twigs, stems, and leaves. 



Insect pests of some leguminous plants, A. Rutherford (Trop. Apr. 

 [Ceylon], 43 (1914), No. ^, pp. 319-323). — This article consists of miscellane- 

 ous notes on the insect enemies of leguminous plants in Ceylon. 



Pests and diseases of the coconut palm, W. W. Froggatt (Dept. Agr. X. S. 

 Wales, >S('i. Bui. 2. 3. cd., rev. and cnl. (1914), pp- 63. fign. 4^). — ^A revised and 

 enlarged edition of the bulletin previously noted (E. S. R.. 20, p. 60). 



The transmission of swamp fever, .1. W. Scott (Wyoming Sta. Rpt. 1914, 

 pp. 180-188). — This is in continuation of the work b.v Swingle, previously notetl 

 (E. S. R., 30. p. 687). The work of the year was devoted to a study of the 

 .ogents that might be concerned in the external transmission of the infection. 

 By elimination it w^as concluded that the agent or agents must be bloodsucking 

 and that only certain mosquitoes and biting flies have the broad geographical 

 distribution characteristic of swamp fever. For the pui'pose of testing these 

 insects a screened cage of 10-mesh wire. 22 ft. long by 20 ft. wide, was con- 

 structed. 



The experiments, which are describetl in detail, have led to the conclusion 

 that swamp fever can be, and under natural conditions probably is. trans- 

 mitted by biting insects. In the investigation conducted the infection was trans- 

 mitted either by the stable fly (Stonioj-ys calcitrans) or by certain mosquitoes, 

 or both, the author being of the opinion that the stable fly was the agent re- 

 sponsible. 



The control of chicken mites and lice, R. M. Siikrwood ( loica .Sf/o. Circ. 19 

 (1914). pp. 2). — A brief description is given of these common fowl parasites 

 and means for their control. 



Cyanid of potassium in trees, H. A. Surface (Science, n. -scr., 40 (1914), 

 No. 1041. pp. 8-'>2, 853). — Replying to an article by Sanford relating to the 

 subject, pi-eviously noted (E. S. R., 32. p. 152). the author calls attention to 

 observations of the use of cyanid of potassium, chlorate of potash, and sulphate 

 of iron. Hundreds of trees treated by an agent of a company engaged in the 

 btisiness upon examination showed no infestation by the San Jose scale, while 

 on others the scale had not been injuriously affected. A large number of the 

 trees are said to have been killed by the treatment. 



The author concludes that while some chemicals may be taken up in the 

 trees, and may even destroy some insects, it is evident that they may be in-
