following number of species for the other insular faunas : — New 

 Zealand has three species, the Society Islands two, the Galapagos 

 Islands one, the Ladrone Islands one, Japan two, Ceylon and Sumatra 

 one, St. Helena two, Madeira and the Canary Islands one, the Azores 

 one, Jamaica three. The palaearctic region (exclusive of the Atlantic 

 Islands) has thirteen species, the Ethiopian region four, North America 

 live, and the American continent south of Texas twelve species. In 

 tropical Asia (exclusive of Ceylon and the Sunda islands) the genus has 

 not yet been met with. It is probable that most of the Pacific insular 

 groups have their peculiar species of this genus, but we still know 

 practically nothing of the Hemipterous fauna of many of these 

 islands. Nysius thymi, Wolff, has the widest geographical range, 

 being distributed througb Europe and Siberia, and over a great part 

 of the United States and British America ; according to Buchanan 

 White it also occurs in St. Helena. 



I take this opportunity of correcting the synonymy of a species 

 of Nysius. N. zealandicus, Dall., must retain its older name, clavi- 

 cornis, Fabr. Stal was wrong in citing " Lygceiis clnvicornis, Eabr., 

 Ent. Syst., iv, 169, ex parted The description of Pabricius, loco citato, 

 exclusively refers to the New Zealand species.

ON TWO NEW SPECIES OP EETEROMERA FROM JAPAN. 

 BY G. LEWIS, F.L.S. 



I have in preparation a paper on the Japanese Seteromera, which 

 comprises about eighty species, but as there will be some delay in its 

 publication, I have decided to print in advance a note on two species, 

 of which I have distributed specimens with manuscript names.
