 with Sinapis arvensis (charlock) ; spraying witli kerosene and soap, 

 Paris green or barium chloride. 



Among Dipterous pests, Oscinella frit, L., injured the seedlings 

 of winter crops in the district of Tcherkassi. Phyfotnyza sip., probably 

 <dhicejps, Meig. {pisi, Kalt)., was observed in the larval stage on leaves 

 of peas in April in the government of Charkov. Mines thought to 

 have been due to P. geniculata, Macq., were observed in the parenchyma 

 of cucumber leaves.

The Cryptophagid, Leucohimatiimi langi, Solsky, was found on 

 millet infested with Ustilago panici miliacei, Wint., on 30th July, the 

 beetles being inside the envelope of the fungus ; they were also found 

 on a vine leaf infested with Plasmophora viticola : there seems to be 

 no doubt that these beetles feed on fungi and probably are concerned 

 in tl eir distribution.

Prior to 1897, black pine trees in Crimean forests were injured by 

 caterpillars of Rhyacionia {Retinia) buoliana. Since that date the 

 following pests have been recorded : — Young oaks were frequently 

 attacked by pests, such as Phalera bucephala, L., more or less consider- 

 able outbreaks of which occurred nearly every year in the second half of 

 the summer. Zeuzera pyrina, L. , as well as Ceramhyx and Purpuricenus, 

 also did damage. Owing to the fact that in the Theodosia mountains 

 the mountain maple bears fruit w'hen very young, and is also attacked 

 by the fungus, Rhytisma acerinum, it is so much weakened that it falls 

 an easy prey to Agrilus viridis, L. Young maples attacked by this pest 

 almost invariably die, while in the case of large outbreaks older and 

 healthy trees are damaged. It was first observed in 1904, and the 

 cutting and burning of the infested trees seems to be the only prac- 

 ticable remedy. The acute-leaved maple {Acer acuminatum) is less 

 subject to attack by these pests. Elm trees were frequently attacked 

 by Phalera bucephala, without, however, suffering great injury. Pear
