SOME RUSSIAN ECONOMIC ENTOMOLOGY. 

 By E. V. WILCOX, Department of Agriculture, Washington, D. C. 



A.S is well known to all scientific workers, the Russians are very active 

 along most lines of natural science, and the published results of their 

 investigations are of great value and importance. Unfortunately these 

 results are for the most part published in the Russian language, and are, 

 therefore, less accessible to the average worker than they would be if pub- 

 lished in French or German. Frequently abstracts are published by the 

 authors in French or German periodicals, but the complete articles and 

 illustrations are for the most part found only in the original Russian 

 publications. 



It is the purpose of this note to call attention to a few articles in econo- 

 mic entomology which may be of interest to American workers. The 

 articles referred to are found in two publications. The one is called 

 " Selskoe Khozyaistvo i Lyesovodstvo," and is published in St. Peters- 

 burg by the Ministry of Agriculture and Imperial Domains. It is a very 

 valuable agricultural journal, and contains articles on all agricultural and 

 forestry subjects. The other publication mentioned is the " Year Book" 

 of the St. Petersburg Forestry Institute, the first number of which was 

 published in 1886. The following is a list of the more important articles 

 from the.se two publications which the writer has had occasion to read 

 during entomological work :

 in the governments of Perm, Orenburg and Tobolsk, I. A. Porchinsk' 

 (Selsk. Khoz. i Lye.sov., 1895. No. i, pp. 79-108, figs. 16).— A discussior»
