NARRATIVE OF PROGRESS OF WORK. 73 



related in a later part of this bulletin, and many of them have been 

 described in some detail in Technical Series No. 12, Part VI, Bureau 

 of Entomology, United States Department of Agriculture (1908), 

 by Mr. Townsend. 



Similarly Mr. Burgess, in charge of the Coleoptera, succeeded in 

 a very perfect way in rearing and liberating the important European 

 predatory beetle, Calosoma sycopJianta, as well as some other insects 

 of the family Carabidae. 



While these extensive importations from Europe were going on, 

 Japan had by no means been lost sight of. While it seemed probable 

 that the European parasites in themselves would succeed in reestab- 

 lishing the balance of nature in New England, and in spite of the 

 somewhat dangerous nature of Japanese importations on the ground 

 that the Japanese gipsy moth is probably a different species and 

 might prove in New England even more voracious and destructive 

 than the European moth, there was at no time any intention to neglect 

 Japan in the search for effective parasites. Continuous correspond- 

 ence had been carried on with Japanese entomologists, and some 

 shipments had been made by correspondents which resulted unsuc- 

 cessfully. For some time the Apanteles previously mentioned was 

 the only gipsy-moth parasite known to occur in Japan. Later 

 information was received from Prof. U. Nawa, of Gifu, Japan, to the 

 effect that there exists in Japan an important egg parasite of the 

 gipsy moth. During the previous annual trips of the Chief of the 

 Bureau of Entomology to Europe the European service of collectors, 

 agents, and advisers had been well organized and instructed, and the 

 work during 1908 was reasonably sure to be well continued without 

 further personal consultation; it was therefore decided to interrupt 

 the European trip for 1908 and to send a skilled agent to Japan. In 

 considering the appointment of such an agent, Prof. Trevor Kincaid, 

 of the University of Washington at Seattle, was at once suggested 

 to the mind of the writer, primarily on account of his extraordinary 

 skill as a collector, as indicated in the remarkable results of his work 

 on the Harriman expedition to Alaska in 1899, and also on account 

 of his comparative proximity to Japan and the fact that he was per- 

 sonally acquainted with many persons in Japan. He was therefore 

 recommended to the State officials of Massachusetts for appointment, 

 and was commissioned by the State to undertake the expedition. 

 At the same time he was formally appointed a collaborator of the 

 Bureau of Entomology of the United States Department of Agricul- 

 ture, and the Japanese Government was formally notified by the 

 honorable the Secretary of Agriculture, through the Department of 

 State, of the intended visit, the writer having also notified by per- 

 sonal correspondence some of the well-known Japanese entomologists. 

 Prof. Kincaid sailed from Seattle on March 2, and the results of his
