 gists in Russia. — Jl. Econ. Ent., Geneva, N.Y., xv, no. 2, April 

 1922, pp. 172-176. 



Brief notes are given on the position of systematic entomology

New methods of combating injurious insects include the use of

 migratoria) in the deltas of rivers, where the dense growth of cane 

 renders ordinary spraying operations impossible.
