Abretic acid, Kreoliii, and Antinonnin. !Nbne of them proved effica- 
cious either as fungicides or insecticides, with the exception of Anti- 
nonnin. Concerning this substance Mr. Lodenian finds that it must be 
kept moist, else it becomes dangerous to handle. When used alone the 
action upon foliage is extremely caustic and the substance must be 
applied highly diluted. Lime reduces its caustic action, but it possesses 
no practical value in destroying insects by contact. On the whole, the 
Bordeaux mixture remains the best fungicide and Paris green and Lon- 
don purple the best general insecticides. 
The Entomological Society of Ontario. — We have just received the 
Twenty-fourth Annual Report of the Entomological Society of Ontario, 
covering the year 1893. It is, as usual, full of interesting matter and 
contains a number of important articles. As a frontispiece is given an 
excellent portrait of Rev. C. J. S. Bethune. for so many years con- 
nected with the Society and with the development of economic ento- 
mology in Canada. The annual address of the President. Mr. W. Hague 
Harrington, treats of several insects of economic importance, including 
the Larch Saw-fly, Rose Saw-flies, Canker Worm, and a number of less 
important species, concluding with a review of the entomological pub- 
lications of the year. Other contributors to the Report are Mr. James 
Fletcher, who presents an account of the injurious insects of the year; 
Rev. T. W. Fyles, who writes a most interesting article upon the ento- 
mological mistakes of authors, from Spenser to Fenimore Cooper. Mr. 
Fyles also contributes an article on the season of 1893, giving a record 
of his captures. Mr. J. Alston Moffat gives a most interesting article 
on the subject of mosquitos; Mr. Harrington a note on Canadian L^ro- 
ceridae, and some additional notes on Japanese insects; Rev. W. J. 
Holland some notes and queries; Mr. T. J. MacLaughlin a popular 
article on the Dragon Fly; Mr. William T. Davis, the song of Thy- 
reonotus, and Mr. Fletcher again, notes on some of the more impor- 
tant entomological exhibits at the Chicago Exposition. The volume 
concludes with an extended account of the Fifth Annual Meeting of 
the Association of Economic Entomologists, printing a number of the 
papers in full.
