February, ’24] crossman & Webber: gipsy moth parasites 
71 
The empty cocoons of Apanteles vitripennis were very common at this 
infestation. They were also seen scatteringly at the infestations which 
were found in France, Italy and Sicily, but at the latter place Apanteles 
melanoscelus far outnumbered vitripennis. A. melanoscelus is one of the 
European parasites which is now well established in the United States, 
but as vitripennis is not here, arrangements were made with the author¬ 
ities in Spain and with Dr. W. R. Thompson of the Bureau of Ento¬ 
mology at Hyeres, France, to make some shipments during the summer 
in an attempt to establish this species in America. A few shipments 
were received at the laboratory but as the Apanteles which were re¬ 
covered were all males, no colonization resulted. 
Germany was visited next, and was scouted very thoroughly. More 
gipsy moth infestations were found here than in France or Italy, but 
they too were in all cases very light. The heaviest infestations were 
found in the vicinity of Berlin, and the fact that nine men collecting 
for two days during the first week in July and again for two days in the 
middle of July were able to collect only 574 larvae indicates the scarcity 
of dispar in this area. These larvae were dissected to determine the 
percentage of parasitism, which was found to be very low. 
By correspondence it was learned that conditions were similar over 
most of Europe and no infestation was heard of except a very light one in 
Hungary from which a few larvae were received in Berlin. 
Because of the scarcity of the Gipsy Moth and of the Brown-Tail 
Moth in 1922 in Europe, it was not possible to make any large shipment 
of their parasites. The parasite problem was discussed with many 
entomologists and many records were made of previous infestations. 
A manuscript of the results of the Japanese investigations is being pre¬ 
pared by Dr. Summers. 
The senior writer went again to Europe in March 1923 and this time 
he was accompanied by Mr. R. T. Webber of the Bureau of Entomology. 
Dr. J. N. Summers of the Bureau visited Japan a second time. In 
Europe: France, Spain, Italy, Germany, Austria and Hungary were 
visited by the writers, with results similar to those of the previous year, 
except that the infestations in Spain were much heavier and those in 
Germany had increased slightly over conditions in 1922. In Hungary 
near Budapest, in company with Prof. J. Jablonowski, Director of the 
Experiment Stations of Agriculture, a light gipsy moth infestation was 
found. Through the kindness of Dr. G. Horvath, Director of the 
National Museum at Budapest, and Dr. A. Schmidt, an entomologist of 
the Museum, an assistant, Mr. J. Ujhelyi, also of the Museum, was
