but that a dose of 5-7 grams to a depth of 6 or 7 inches destroys all the 

 larvae, 35 grams being sufficient for an area of 5| sq. feet. The 

 stupified larvae died in 1 or 2 days. The injections were performed 

 witii the " Kober " injector, which is described and figured. Instead 

 of injecting the carbon bisulphide, small balls of cotton wool soaked in 

 it may be buried in the earth by means of a dibble about 2 inches 

 thick, with a cross bar G-7 inches from the end ; the balls should be 

 about the size of a walnut ; in order to facilitate the making of them 

 some tar is added to the cotton wool. The balls are kept in a tightly 

 closed bottle filled with CSo and are quickly removed from the bottle 

 and j)laced in the hole by means of a special hook.

Up to 1914, the caterpillars of Euxoa segetum, Schiff., the most 

 dangerous pest of winter-sown crops, were not much in evidence in 

 the government of Ekaterinoslav, but during that year they appeared 

 in various parts of it and did great damage. These cutworms threaten 

 to be as serious a pest in the near future as is Oria {Tajnnostola) 

 muscidosa to summer-sown crops. A popular account of the pest is 

 given, with descriptions and figures of its various stages. The destruc- 

 tion of weeds, on which the oviposition takes place, and the use of 

 black fallow and occupied fallows are advised [see the Review, 

 Ser. A. ii, p. 316]. Against the caterpillars, trenches round the fields 

 to be protected are recommended.

In this prefatory article, the history of the Entomological Bureau 

 of Charkov is traced. Great outbreaks of wheat chafers {Anisoplia 

 austriaca, Herbst), locusts and the Hessian fly in the South Russian 

 steppes led to the establishment of an Entomological Commission by 

 the Zemstvo of Charkov in 1878 and by that of Odessa in 1882. In 

 accordance with the recommendation of the Entomological Congress 

 held in Odessa in 1887, an Entomologist was appointed by the authori- 

 ties concerned, for the whole of South Russia. The Zemstvo of 

 Taurida was the first to establish in 1893 a special Entomological 

 organisation. In Charkov, the same took place in 1905, as a direct 

 result of great damage to crops done by a species of Euiijgaster. The 

 chief object of the Bureau is the organisation of campaigns against
