In the spring of 1905 an arrangement was made by the United States Department of Agriculture to cooperate with the State of Massachusetts in importing and establishing the natural enemies of the gipsy moth and the brown-tail moth. Dr. L. O. Howard, Chief of the Bureau of Entomology, supervised the work, and until Decem- ber 1, 1911, this arrangement remained in force, the project being financed jointly by the Bureau of Entomology and the State of Massachusetts. Since 1912, owing to the fact that the scope of the work involved nearly all of the New England States, these projects have been carried on solely by the Bureau of Entomology. One of the natural enemies of the gipsy moth, which has long been known in Europe as of prime importance, is a green beetle be- Note.—The writers wish to acknowledge their obligation to the members of the staff "t the Gipsy Moth Laboratory for securing data and carrying on many of the experiments which are only briefly alluded to in this publication.
