76 PARASITES OF GIPSY AND BROWN-TAIL MOTHS. 
official collaborator of the Bureau of Entomology of the United 
States Department of Agriculture, securing leave of absence from 
the University of Washington, proceeded to Russia, and stationed 
himself in Bessarabia for the purpose of collecting and sending para- 
sitized material from that country to the United States. It had been 
noticed by Mr. Vuillet at Rennes during the preceding summer that all 
material coming from Russia had been opened on the journey and had 
deteriorated in consequence. Before Prof. Kincaid's departure from 
America, Russian officials had been communicated with through 
correspondence between the chief of the Bureau of Entomology and 
Prof. Porchinsky, of the ministry of agriculture, and also directly 
between the United States Department of State and the American 
ambassador at St. Petersburg through the instigation of the honor- 
able the Secretary of Agriculture. The United States Government 
was assured that the Russian Government would welcome the expe- 
dition and would facilitate the sending of material in every way 
possible. 
The chief of the bureau landed at Cherbourg May 12. He pro- 
ceeded immediately to Paris, where a conference had been arranged 
in advance with M. Oberthiir, M. Vuillet, and Mr. Henry Brown, the 
latter an English entomologist resident in Paris. At this conference 
it was decided to abandon the forwarding laboratory at Rennes and 
to station Mr. Vuillet, during the forwarding season, at Cherbourg. 
He was instructed to engage quarters at that seaport and to arrange 
for cold-storage facilities, with the intention that shipments from 
France, Switzerland, and Italy should be forwarded to him to be 
kept in cold storage until the date of sailing of vessels, and then 
should be transferred to the cold room of the next steamer, thus 
practically keeping all living specimens dormant from the time of 
arrival in Cherbourg until the time of arrival in New York, making 
the exposure to summer temperature practically only 24 hours or less 
in Europe and 24 hours or less in the United States. In the mean- 
time Mr. Oberthiir was authorized to arrange for an extensive service 
in the south of France, through Mr. II. Powell, of Hyeres, one of 
the agents for the year 1906. The preparation of the requisite boxes 
was intrusted, as in previous years, to the superintendence of Mr. 
Oberthiir, and Mr. Powell was authorized to engage as many col- 
lectors as the materia] would seem to need, with full instructions as 
to packing and shipping to Cherbourg. 
The visitor then proceeded to Wageningen, Holland, where he 
arranged for further assistance from Prof. Dr. J. Ritzema Bos. From 
there lie went to Hamburg, where he arranged with the American 
Express Co. to care for shipments coming from Germany, Russia, 
and Austria-Hungary, arrangements being made to keep the material 
on ice until the next steamer should sail, and in case of the breakage
