232 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 10 



The fifty-third annual meeting of the Ontario Entomological Society was held at 

 the Ontario Agricultural College, Guelph, November 2 and 3, 1916. Dr. L. O. 

 Howard, Washington, D. C, and Prof. P J. Parrott, Geneva, N. Y., were present 

 from the United States, and Doctor Howard gave an evening lecture on "The Car- 

 riage of Diseases by Insects, " which was illustrated with lantern sUdes. The follow- 

 ing officers were elected for the coming year: — President Albert F. Winn, Westmont, 

 Que.; Vice-President, Lawson Caesar, Guelph; Secretary-Treasurer, A. W. Baker, 

 Guelph; Curator, W. Evans, Guelph; Librarian, C. J. S. Bethune, Guelph; Di- 

 rectors, Arthur Gibson, Ottawa; C. E. Grant, Orillia; A. Cosens, Toronto; F. J. A. 

 Morris, Peterborough; J. W. Noble, Essex; W. A. Ross, Vineland Station; Delegate 

 to the Royal Society of Canada, F. J. A. Morris, Peterborough. 



Mr. Otto Heidemann, long connected with the Bureau of Entomology and custo- 

 dian of the Hemiptera in the National Museum, died after an operation, on the morn- 

 ing of November 18 at the Homeopathic Hospital in Washington. Mr. Heidemann 

 originally came to the Department in 1883 and for a number of years was employed 

 as a wood engraver. With the development of photo-engraving his occupation was 

 lost, and in 1893 he began for the first time the study of insects. It is an unusual 

 thing for a man well beyond fifty to take up de novo the occupation which he is to 

 follow ardently for the rest of his life. Mr. Heidemann became known all over the 

 world as an authority on the group of insects which he studied. His address, as retir- 

 ing President of the Entomological Society of Washington on the eggs of Hemiptera 

 was a paper of striking merit. He leaves a widow, Mrs. Mica Heidemann, well known 

 as a sculptress and as a maker of insect models. [L. O. Howard.] 



During the summer of 1916 a successful demonstration in anti-mosquito work 

 was carried out in Minneapolis by the MinneapoUs Real Estate Board. Ten square 

 miles in South Minneapolis were chosen for the demonstration, an area typical of 

 local conditions and of more than average difficulty. C. W. Howard of the Division 

 of Economic Zoology of the University of Minnesota was placed in charge and six 

 University students engaged for the work. The mosquitos mostly concerned were 

 Culex pipiens, Aedes sylvestris, Aedes canadensis, Culex restuans, and Culex tarsalis, 

 but especially the first two. In spite of the many large stretches of swamp and 

 dumping areas, the mosquitos were reduced fully 99 per cent. So marked were the 

 results that there has been a large demand for the continuation of the work next 

 year under the same direction. The City Health Department wiU probably coop- 

 erate and the entire city will be covered. House-fly ehmination will be included 

 with the mosquito work. At least thirty-five men will be needed as inspectors.
