To many persons it may come as a surpTPisetnat, in spite of 

 the terrible war which has affected every c^narter of the globe and 

 paralysed scientific research in so great a part of Europe, the output 

 of pubHcations deahng with Economic Entomology has actually shown 

 a marked increase during 1915. This increase is even greater than 

 would appear from the pages of the Review of Applied Entomology, 

 for it has been impossible for us to obtain access to the great majority 

 of scientific periodicals that have appeared in hostile countries. In 

 this connection, the following table showing the number of articles 

 abstracted in the Review during the last three years, grouped under 

 the countries in which they were published, may be of interest.
