the co-operation of the medical or sanitary corps, the problems relating 

 to flies and other disease-carriers, as well as those concerning body 

 parasites and animal pests. The economic entomologist is also needed 

 to advise and urge the adoption of measures which will minimize 

 the effect of insect ravages, especially upon staple crops, and every 

 effort should be made to forecast, and where possible forestall, insect 

 depredations, rather than to adopt remedial measures after infestation 

 is estabhshed, as the entomologist is frequently called upon to do. 



Brown (W. G.). The Blow-Fly Pest— Queensland Agric. Jl, Brisbane, 

 vii, no. 3 March 1917, p. 119. [Keceived 7th May 1917.] 

 In regard to the treatment of sheep against blow-flies, a suggestion 

 has been made that if sheep are thoroughly washed at the beginning 

 of the summer, thus removing the dirt and grease from the wool, 

 they would be safeguarded against attack. This is probable, because 

 sheep with hght, dry wool and cross-breds are not so hable to attack 

 as merino sheep with dense and greasy wool. Further, experiments 

 with poisonous and non-poisonous dips tend to show that the cleansing 

 effect involved in the process bears more than a small share in the 

 efficacy of the treatment. 



Taylor (F. H.). Malaria Mosquito Survey of Irrigation Areas in the 

 Murray River District.- — Commonwealth of Avsiralia Quarantine 

 Service, Melbourne, Publication no. 12, 1917, 32 pp., 7 maps, 

 28 figs. 

 The purpose of this survey was the examination of the principal 

 irrigation districts bordering on the Murray Kiver, in order that the 

 absence or prevalence of the malaria-carrying species of mosquito 

 should be determined. This is considered a matter of fundamental 

 importance in view of the fact that preparations are being made in 

 many of these districts to estabhsh there men returned from mihtary 

 service abroad, many of whom are infected with malaria. The 

 survey was conducted immediately after a period of exceptional rains 

 over the whole area, and abnormal flood conditions were existent, 

 the prevalence of mosquitos being greater than usual. Anopheles 

 (Nyssorhynchus) anmdipes occurs throughout the irrigation area m 

 considerable numbers, especially in the neighbourhood of human 

 habitations. Detailed reports from the various irrigation districts 

 are given, the conditions of each being described and the number of 

 Anophehnes and Culicines recorded. The latter included Cnlicada 

 sp., Grabhamia sp., Ochlerotatus (Scutomyia) notoscriptus, Skuse, Stego- 

 myia sp., Cidexfatigans and C. sitiens. In one district near Lake Boga, 

 mosquitos were remarkably scarce, probably owing to the presence of 

 large numbers of dragonflies, especially Xanthagrion erythroneurum, 

 Selys, and Austrolestes annulosus, Selys.

 Bidl Soc. Path. Exot., Paris, x, no. 2, 14th February 1917, 

 pp. 95-98. 

 Iguana nudicollis, found in Guiana, is frequently infested with 



Plasmodium carinii, sp. n., which is considered to be distinct from 



other species found in hzards. This Haematozoan and its alhes bear 



a close resemblance to Plasmodium praecox.
