Caterpillars of Euxoa segetum have appeared of late years in many 

 parts of the Province of Don, gradually increasing in numbers and 

 spreading over new and large areas. The author carried out obser- 

 vations on this pest on some experimental fields in one district both 

 in 1914, when reploughing the infested areas gave satisfactory results, 

 and again in 1915. The results of these observations are summarised 

 as follows : — Rye is injured to a greater degree than winter wheat ; 

 crops grown on occupied fallow lands [see this Revietv, Ser. A, ii, 

 p. 316] are far less injured than those grown on black or clean fallow ; 

 early sown crops are more injured than later ones ; crops sown on late 

 ploughed fallows are more injured than on early ploughed ones. The 

 most effective remedy is to plant early trap- crops, preferably of rye 

 in strips, separated from the rest of the field by trenches, these strips 

 being subsequently sprayed with Paris green (2-4 lb. of green, 4-8 lb. 

 of freshly slaked lime in about 110-120 gallons of water).

This paper reviews the proceedings of the first annual meeting of 

 th e Russian Society of Workers in Applied Entomology, which took place 

 in Kiev on 3rd-9th November 1916. The meeting was attended by 

 representatives of the great majority of Russian entomological organi- 

 sations. The papers read included those by Professors N. M. Kulagin 

 and A. A. Silantiev on the organisation of a Central Entomological 

 Bureau. This question was further considered by a Committee 

 consisting of S. A. Mokrzecki, V. G. Averin, B. P. Uvarov and V. V. 

 Dobrovliansky, and it was decided that a Central Bureau should be 

 established in Petrograd, at the Department of Agriculture, and that 

 its object should be to co-ordinate the work of the local Bureaus and 

 also to supervise the execution of works of Imperial importance. 

 This would include : — the preparation of a scheme for providing for the 

 establishment of local entomological bureaus and assisting them in identi- 

 fying insects, procuring the necessary apparatus, etc., and examining 

 sprayers and insecticides ; the drawing up of legislation for the control 

 of pests in Russia and advising the Government as to money-grants 

 in this connection ; the publication of entomological literature and 

 the training of a stai? of experts. The Bureau should be in charge of 

 a Committee, consisting of representatives of the Departments of 

 Agriculture and Forestry, the Institute of Experimental Agronomy, 

 the All-Russian Agricultural Chamber, the Russian Society of Workers 

 in Applied Entomology, the local Entomological Bureaus and the 

 chairs in Applied Zoology and Entomology at the Russian Universities. 

 In order to pro\nde for a sufficient staff of expert entomologists, the
