SUMMAEY OF THE TTEMIPTERA OF JAPAN, PRESENTED 

 TO THE UNITED STATES NATIONAL MUSEUM BY PRO- 

 FESSOR MITZUKURI.

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.
