of vines, Termes lucifugus, Rossi, was observed in a locality in which 

 it had already been noticed some years before and where it appears 

 to be now firmly established, notwithstanding the severe winters. 

 Eulecanium {Lecanmm) robiniarum, Dough, which has during late 

 years greatly developed on white acacia, has quite disappeared during 

 the year under report. 



Experiments with a new insecticide, " Uraniagriin," an arsenica- 

 preparation in the form of a fine powder of a bright green colour, 

 which can be applied without lime, are recorded. In the proportion 

 of 1 per 1,000 of water, this insecticide was very effective against 

 caterpillars of Hyponomeuta malinellus, Malacosoma neustria and 

 Eujproctis chrysonJioea, the death rate being the same as from Paris 

 green in salammoniac. No scorching of the leaves was observed^ 

 Although the specific gravity of Uraniagriin is 0-75, being less than 

 that of Paris green, which is 1'2, the powder nevertheless settles down 

 somewhat quickly on the bottom of the vessel.

This book describes the author's views on Economic Entomology in 

 the United States, acquired during visits paid by him to that country, 

 first as a member of the American Agency of the Zemstvo of the 

 government of Ekaterinoslav during 1910-1911, and again in April 

 1912, when he was deputed by the Zemstvo of the government of 

 Charkov to study this subject there at the expense of the Department 

 of Agriculture. The position of Economic Entomology in the United 

 States, covering every branch of its activity, and the organisation and 

 the method of working of the various departments of the Entomological 

 Bureau of Washington, are fully described, as also are the stations. 

 in the individual States. Special attention is paid to the scientific 

 researches conducted by the Bureau and its branches, and descriptions 

 are given of the w^ork that is being done on various pests of Agriculture, 

 their biology, parasites, etc. Special chapters are devoted to the 

 American Association of Economic Entomologists, the literature on 

 Entomology appearing in America, and with the most important 

 insecticides and sprayers in use.

 Fiscal Year ending 31st March 1913. — Dom. of Canada Dept. Agric.,. 

 pp. 501-518. [Received 2nd November 1914.] 



Most of the records of insect pests dealt with in this report have 

 already appeared in this Review. The area of infestation by Evproctis 

 chrysorrhoea (browntail moth) in New Brunswick increased from about 

 400 square miles in 1910 to about 6,400 square miles in 1911 ; the 

 infestation was light, only 2,452 winter webs being found. In New 

 Brunswick, birds contributed to the destruction of the larvae. The 

 discovery of the larvae of Compsilura concinnata in caterpillars 

 of Hyphantria cunea, three miles from the point where these 

 parasites had been liberated, showed that the Tachinids had crossed the
