ing the foreign parasites of the gypsy and brown-tail moths, I be- 

 gan a correspondence with Japanese and European entomologists, 

 seeking for their co-operation in the effort. Soon after you were 

 good enough to place me in charge of the foreign work under a 

 State appropriation for the same purpose, and this responsibility 

 was accepted with the permission of the Secretary of Agriculture. 



Japanese entomologists, and especially Mr. Kuwaua of Tokio, 

 are making an effort to send to this country living specimens of an 

 important egg parasite of the gypsy moth which is said to exist in 

 Japan. The same entomologists and the Rev. H. A. Loomis of 

 Yokohama are endeavoring to send over in living condition and 

 unparasitized a Braconid parasite of the genus Apanteles of the 

 gypsy moth. One sending of Apanteles was received at Boston 

 during the summer, and this is the only shipment which has reached 

 this country from Japan during the present year. 



On the 3d of June I sailed for Europe for the purpose of organ- 

 izing a systematic search for parasites of these two insects, and to 

 secure, if possible, continuous shipments throughout the breeding 

 season and during the winter of parasitized specimens of both 

 species. My personal acquaintance with the official entomologists 

 of Europe and my long-continued and very friendly official rela- 

 tions with these gentlemen have greatly facilitated my efforts in 

 this direction, and all have expressed a hearty desire to co-operate 

 with the United States government and with the government of the 

 State of Massachusetts in their work. Their personal endeavors 

 have been at our service, and their expert advice has been of much 

 assistance. In many cases they have been good enough to select 

 and recommend agents, who have been paid for their services from 

 the State appropriation. The personal services of the official ento- 

 mologists, however, have been gratuitous ; and in some instances I 

 have been able to repay them for their courtesy by sending abroad 

 American parasites of injurious insects accidentally established 

 in European countries. 



The officials who were interviewed and who have placed their 

 services at the disposal of this country are as follows : Dr. Felipe 

 Silvestri, entomologist of the Royal Agriculture Station at Portici, 

 Italy, and his first assistant, Dr. Gustavo Leonard! ; Prof. Antonio 

 Berlese, director of the Royal Station for Agricultural Entomology 

 at Florence, and his principal assistants, Drs. Del Guercio and 

 Ribaga ; Dr. Anton Handlirsch and Dr. Hans Rabel of the Royal 

 Natural History Museum in Vienna ; Dr. Alexander Mocsary of 

 the Natural History and Ethnological Museum in Budapest ; Prof. 

 Joseph Jablonowski of the Agricultural Experiment Station in
