and often but a single generation annually. The slowness of breeding 
of the American species is a very great bar to its usefulness in the 
latitude which includes the principal deciduous-fruit interests of the 
United States. 
These facts were thoroly demonstrated from the breeding records 
of the material sent from China and Japan. Several sendings were 
made by the writer, but unfortunately most of the specimens died in 
transit or during the first Avinter. Two individuals, however, sur- 
vived, and during the first summer, that of 19<)2. from these two some 
5,000 or more beetles were secured. The breeding was first carried

on in cages (PL VIII), but afterwards the beetles were liberated in the 
small experimental orchard attached to the insectary of the Bureau. 
A good many colonics were sent out to different States, both north 
and south, in the summer of 1902, many more in the summer of L903, 
and a few additional colonies in 1904. Many of these colonies were 
liberated under rather unfavorable conditions, or. in other words, 
where there were very few infested trees, and the beetles probably 
became scattered and lost. The best success came with certain colo- 
nics sent t<> Georgia, and especially the notable case of the colony at 
Marshallville. This last was in an orchard containing some L7,000
