This address, delivered at the inaugural meeting of the Society on 

 the 14th March 1914, deals with its aims and objects. Some figures, 

 are given illustrating the great importance of insects to man and 

 agriculture. In 1899 over 70,000 acres of sugar-beet were destroyed 

 in the government of Kiev by Bothynoderes (Cleonus) punctiventris, 

 Germ., resulting in a loss of over 400,000 tons of sugar, while in 1900 

 the Zemstvo of Cherson had to pay over £33,000 for the collection of 

 some 145,000 bushels of Anisoplia.

In 1914 the Zemstvo of the government of Orenburg, estimating^ 

 that some 19,000 acres were infested with the egg-clusters of locusts, 

 voted about £2,000 for the campaign against them, of which about 

 £900 was assigned to investigations in spring and autumn as to the 

 deposition of egg-clusters. The author was in charge of the campaign, 

 which was confined to an area of some 8,000 acres. During the 

 prehminary investigations it was found that only a small per- 

 centage of the egg-clusters were infested with parasites. Spraying was. 

 carried out with Paris green (3 to 4 lb. in about 70 gallons of water, 

 according to the age of the locusts), oxide of zinc (l|-2 lb. in 70 gallons, 

 of water) and sodium arsenite (l|-2 lb. in 70 "gallons of water). 

 The total cost amounted to over £1,650. The principal species present 

 were Gomphocerus sibiricus and Arcyptera flavicosta. Owing to the 

 lack of knowledge of the life-history of these species, the best method 

 of conducting the campaign against them is still a matter for investi- 

 gation ; in this connection it is pointed out that these species do not 

 live in dense swarms, as is the case with locusts found in Northern. 

 Caucasia. Experiments conducted with poisoned baits showed that 

 the best consists of a paste prepared from 20 lb. of bran. 10 lb. of 

 molasses, 1 lb. of arsenic and about 2 gallons of water ; this mixture 

 can be strewn about in fine particles.
