NARRATIVE OF PROGRESS OF WORK. 7 
so heartily interested in the experiment, that he considered them 
not only perfectly able, but perfectly willing to carry on the work by 
themselves. After this authoritative expression of opinion from one 
who knew the ground so well, the visitor asked Mr. Kincaid whether 
he would care to spend the early summer months of 1909 in Russia, 
and, upon his affirmative reply, later recommended his reappointment 
to the Massachusetts State authorities for that purpose. 
During the autumn and winter shipments of eggs of the gipsy 
moth were received from Japan, principally from Prof. Kuwana. 
From these eggs were reared numerous specimens of Anastatus bifas- 
ciatus Fonse., a previously known European parasite of these eggs, 
and of another parasite belonging to a genus and species new to 
science (since named by the senior author Schedius kuvanx) which 
has turned out to be an important primary parasite and which is 
considered in later pages. During the winter, also, Prof. Jablonowski, 
of Budapest, sent over several thousand egg masses of the gipsy moth 
collected in various localities in Hungary. After they arrived in 
Massachusetts there were reared from them and liberated under the 
most favorable conditions more than 75,000 adult individuals of 
Anastatus bifasciatus. This was a surprising thing to the laboratory 
workers, since less than 1,000 parasites of this species had been 
received from all localities, the earlier ones having come from southern 
Russia and from Japan. 
The winter of 1908-9 was spent at the laboratory, in additional 
rearing operations, some of them on a large scale, and in studying the 
parasites already reared, and planning for the coming summer. 
As it happened, during the winter the brown-tail moth was intro- 
duced into the United States upon nursery stock from France in 
large numbers. Shipments of nursery stock bearing winter nests 
of this insect were sent to many States of the Union. Fortunately 
this was discovered early in the winter, and through prompt action 
and the cooperation of the customs officials and the railroads prob- 
ably every sending was traced to its ultimate destination, and was 
there inspected and the nests destroyed either by State officials or by 
persons appointed for this purpose by the United States Department 
of Agriculture. 
In the spring of 1909 it seemed necessary for the chief of the 
bureau to proceed to Europe for the purpose of making an investi- 
gation of the European methods of growing nursery stock, with a 
view to the prevention of similar introductions in the future either 
by general legislation by the United States Government or in some 
other way. On this trip he utilized the opportunity to consult 
further with European agents in the importation of the parasites 
and to arrange for the summer’s work. 
In the meantime Prof. Kincaid, whose appointment had been made 
by the State of Massachusetts, and who had again been made an
