SUMMAEY OF THE TTEMIPTERA OF JAPAN, PRESENTED TO THE UNITED STATES NATIONAL MUSEUM BY PRO-FESSOR MITZUKURI. By Philip R. Uhler, President of the Maryland Academy of Sciences. The following list, with the descriptions of species supposed to be new to science, includes the collection of Japanese Hemiptera, which was exhibited at the World's Columbian Exposition in Chicago, and subsequently presented to the United States National Museum by Doctor K. Mitzukuri, Professor at the Imperial University of Tokio, Japan. It embraces the greatest number of si^ecies of this order which have thus far been made accessible for scientific study. The museums of Europe are not rich in collections of these insects from Japan, and it is only within the last twenty-five years that much attention has been given to their acquisition. Thunberg was the first to describe any con-siderable number of the species, and a lapse of thirtj^-five years took place before Motschulsky next took up the subject and described a few additional species. The later authors who have recently made known the largest proportion of the species are Messrs. Scott, Distant, and Horvath, but they seem to have been unacquainted with a considerable number of the species enumerated in the present paper. In all, about 137 species are present in this collection, and they appear to have been taken generally in the more southern and warmer parts of the islands. A few more than twenty species described from other localities in the Empire are not among those here recorded, but they are only a small part of the ample fauna yet to be recognized when the various districts of the country shall have been closely examined.
