Abstract

Since 1920, workers on the Japanese beetle project of the United States Bureau of Entomology have been searching in the Orient for suitable parasites to introduce into the United States for use against the Japanese beetle in this country. In the course of this work a large amount of material on the genus Tiphia was gradually accumulated, and considerable information on the ecology and life history of a number of the species was gathered. Satisfactory determinations of these species, however, could not be obtained. The writers therefore began during the winter of 1926-27 a study of the material accumulated in the Japanese Beetle Laboratory and in the United States National Museum. It was soon found that a considerable number of species was represented. The original descriptions of many oriental forms proved unsatisfactory because most of the characters used in these descriptions appear, in the light of present knowledge, to have little or no diagnostic value. Fortunately, Mr. A. B. Gahan of the Bureau of Entomology was able to spend a few days examining types in the British Museum and comparing them with specimens sent him and with manuscript keys to species, and was able to indicate the identity of several species with previously described forms. In addition to these species, a number of others, new to science, are described in this paper.
