The dry weather of 1911 again affected these weevils in the same way 

 and it is not expected that this pest will be serious in 1915. The 

 various species were caught in the following proportions by means of 

 nets :- — Apion apricans, 55"7 per cent. ; A. aestivnm {trijolii), 36'6 

 per cent. ; A. varipes, 4*8 per cent. ; A. ftavipes, 1*9 per cent. ; 

 A. senicidns, 0*8 per cent. ; A.frumentarium, 0*1 per cent. ; A. viciae, 

 O'l per cent. 



Trachea {Hadena) basilinea, F., injured rye and wheat in some parts 

 of the government in 1913 ; the number of moths caught in molasses 

 troughs amounted to about 50 per cent, of the whole. They were 

 chiefly on the wing during the second half of May and the first half of 

 June. No complaints of this pest reached the station in 1914, and 

 •only small numbers were noticed during June. Feliia (Agrotis) 

 ■exclamationis, L., is usually found together with Euxoa segetum, but in 

 considerably smaller numbers ; thus in 1910 there were caught in 

 molasses troughs in one district 86-5 per cent, of the latter and 2-8 

 per cent, of the former; in 19ir the figures were: — 45-5 per cent, 

 and 8 per cent. ; in 1912, 48-6 per cent, and 8-2 ; in 1913, 77-1 per 

 cent, and 9 per cent., and in 1914, 41*6 per cent, and 21-5 per cent. 

 In 1914 the numbers of F. exclamationis caught were in some localities 

 nearly equal to those of E. segetum. The two species appear about 

 the same time, and though the flight of F. exclamationis lasts longer, 

 the molasses troughs used for E. segetum will also prove effective 

 a.gainst it.

The following insect pests are reported from various parts of Russia. 

 The Hessian fly [Magetiola destructor] was observed both on winter 

 and summer sown wheat and on barley in Central Russia and along 

 the Volga. Anisoplia austriaca appeared in large numbers in Central 

 Russia, in Novorossia (South Russia) and in the government of Kiev, 

 ]>ut owing to the rapid ripening of the crops, it did damage for brief 

 periods only. Oscinella frit was reported from Saratov, A'oronezh and 

 elsewhere in the south-west on barley and oats. Phlgctaenodes (Botys) 

 ■sticticalis injured beet and vegetables in Poltava and Kiev, while peas 

 in some localities on the Volga and in Tambov, Kiev and Ekaterinoslav 

 suff"ered from Aphids. Haliica sp. did considerable damage in June 

 and July to beets, hnseed and vegetables. Thrips in Voronezh and 

 Oria {Tapinostola) muscidosa in the province of Don, were only present 

 sporadically. Locusts appeared in the steppe provinces of Siberia 

 and also in the governments of Tomsk and Enisseisk, but over limited 

 areas and did not do much damage.
