Mosquito Investigation Committee, the title The South- Eastern 

 Naturalist would be a misnomer for the year 1920. Although much 

 overdue this hardy annual is always welcome as a reminder of pleasant 

 days spent during the Annual Congress, serving as a means of 

 association between societies in the S. -Eastern area of England. We 

 are glad that the Council has returned to our own printer, with the 

 style of the book as of yore and the Treasurer's blessing. 



The staff of the New York Agricultural Experimental Station 

 continue to distribute the admirable pamphlets containing accounts 

 of their experiments on the control of insect pests. " The Control of 

 the Pear Thrips {Taeniotl trips pyri)," by C. K. Phipps, one of the most 

 destructive pests in the State, and the summary of " Insect Injuries 

 in Relation to Apple-grading," by B. B. Fulton, are to hand. Both 

 are well illustrated, the latter with coloured plates. There are descrip- 

 tions in the latter of the following insect injuries and suggestions 

 for their prevention : — Codling moth Carpacapsa (Gydia) pomonella, 

 Lesser apple-worm Enarmonia prunivora, Oriental fruit moth Laspey- 

 resia molesta, Apple maggot Rhagoletis pomonella, Green fruit-worms 

 Graphipliora alia, Xylina antennata, X. laticinerea and X. grotei, Fruit- 

 tree leaf-roller Archips argyrospila, Bud moth Tmetocera ocellana, 

 Apple bug Lygidea mendax, Red bug Heterocordylas malinus, Plum 

 Curculio Conotrachelus nenuphar, Apple Curculio Anthonomus quadri- 

 gibbus, Rosy apple-aphis Aphis sorbi, San Jose scale Aspidiotis 

 perniciosus, Rose chafer Macrodactylus subspinosus, case-bearers Goleo- 

 phora fletcherella and C. malivorella, Apple-seed Chalcid Syntomaspis 

 druparum, etc. 



The Fiftieth Annual Report of the Ent. Society of Ontario, for' 1919, 

 contains among other items " Insect Outbreaks and their Causes," by 

 J. D. Tothill, showing that prevalence of an insect pest has usually 

 turned out to be due to the absence of an effective insect control ; the 

 results of the experiments on the " Control of the Cabbage Maggot 

 Phorbia brassicae," which have been systematically carried out in each 

 state; "The Present Status of Mill-infesting Pests in Canada," 

 mainly consisting of Ephestia kiihniella, the Mediterranean Flour-moth 

 and the Flour-beetles Triboliiun spp. ; " The Federal Plant-Quarantine 

 Act " and its application and results therefrom, etc., with numerous 

 reports on Insects of the year and Entomological Progress. 



Among the Separata from the Proc. U.S. National Museum, 

 Washington, we have received " Genotypes of the Elaterid Beetles of 

 the World," by J. A. Hyslop, with fullreferences ; "The N. American 

 Ichneumon-flies of the tribe Ephialtini,'' 1 by R. A. Cushman, and 

 ■" The Dipterous Genus Dolichopus, Lafcr., in N. America," by Van 

 Duzee, Cole and Aldrich, in which the authors say that this Dipterous 

 family " offers such a storehouse of material bearing upon the 

 Darwinian theory of sexual selection that its many beautiful and 

 easily classified species ought to be much more widely known among 

 those who give attention to the larger biological problems. In the 

 present paper a large number of secondary sexual characters are 

 figured, not only as aids to identification, but to give some idea of the 

 wealth of beautiful structures which have been developed in the males 

 of this genus." There are sixteen plates containing several hundred 

 •figures besides figures in the text.
