The extraordinary interest attaching to the entomological features 

 of Japan renders any precise and detailed information particularly 

 welcome, especially to the student of geographical distribution. Ex- 

 plorers and passing travellers have rendered good service in making 

 known its rhynchotal treasures, but the scientific study of any special 

 fauna is scarcely placed on a satisfactory footing until native or foreign 

 residents apply themselves to its elucidation in the country itself. 

 Mr. Nawa, of Gifu, has been collecting the Japanese Rhynchota 

 for bome little time, and inciting his friends and neighbours to 

 emulation in the same pursuit, though, unfortunately, Mr. Nawa's 

 observations have, until recently, been published entirely in Japanese. 

 The mere fact that his journal, ' The Insect World,' a monthly maga- 

 zine of some forty pages a month, entirely (except the title) in Japanese, 

 is now well towards the completion of its fourth year, is an eloquent 

 testimony to the grip that entomology has taken of our far-eastern 

 confreres, though the language in which it is couched must necessarily 

 limit its audience in the west. We ourself can only say that notes of 

 rhynchotal interest have appeared from time to time, as evidenced by 

 the figures of Corixa substriata, various Ricaniiua^ and Cixiinie, as well 

 as of a number of others un-named. In the seventh number of the 

 third volume (July 15th, 1899) two photographs are reproduced 

 (plate vii.) of the personnel of an entomological expedition, numbering 

 some forty individuals, a muster which puts to shame some of the 

 field-meetings of our most flourishing London societies. Mr. Nawa is 

 much to be congratulated and applauded for the excellent work he is 

 doing in popularising the study of insects among his countrymen. 



His collections have, in part, also lately been scientifically worked 

 out by Dr. Uhler, the veteran rhynchotist of Baltimore, and by Dr. 

 Matsumura. The bugs exhibited at the World's Columbian Exhibition 

 in Chicago, and subsequently presented to the U.S. National Museum 

 through Dr. Mitzukuri of Tokio, were (we learn from Dr. Matsumura) 

 collected by Mr. Nawa ; six new genera and close upon fifty new 

 species ''= were then added to science. Quite recently Dr. Matsumura 



■'- ^^ Lhnnotrechiis elongatus," Uhler, does not belong io Limnotrechus 

 (i. e. to the t;ypical subgenus of Gerris) ; the descriptions of the antennae 

 and of the conuexival spines proclaim it a '' Limnometra'' (or possibly a 

 '■'■ Limnoporus''). There is probably a misprint in the first three ines of 

 p. 275.
