Bonn, Wiesbaden, Rheingau, Mayence, Offenbach, 

 Mannheim, Karlsruhe, Freiburg), and a few west 

 of the Rhine (neighbourhood of Kreuznach, Neudorf 

 in Alsatia, and Basle in Switzerland). It is generally 

 distributed in Poland, Silesia, Prussia, Mecklenburg, 

 Schleswig-Holstein, Denmark, Oland, Gothland Island, 

 and Sweden, as far north as Upsala, but only found iu 

 two localities in Southern Norway (Hof in Jarlsberg, 

 and Hval Oerne). It is more local in the province of 

 Saxony, the kingdom of Saxony (Leipzig and Dresden), 

 and in Austria-Hungary, where it is on record from 

 the plains of Transylvania, Budapest, Pressburg, 

 Franz Josefsland, and Marchfeld in Lower Austria, 

 Karlovac in Sclavonia, Agram, and Fiume in Istria. 



Its distribution in Asia is not yet made out with 

 anything like precision, owing to the fact that it has 

 so long been confounded with R. femporaria, and of 

 late with R. camerani. I have examined specimens 

 from Sarai Gor, on the Ob, the valley of Buchtarma, 

 Altai, and the Kirghiz Steppes, and Bedriaga records 

 the species from the Karakali Mountains. The speci- 

 mens from Sultania in Persia, and Lake Gokcha, 

 referred to this species by de Filippi, belong to the 

 following, R. camerani, as I am informed by my friend 

 Dr. de Bedriaga, who has examined the types at my 

 request. 



The three specimens figured on PI. XVIII are 

 from Magdeburg, received from my obliging corres- 

 pondent Mr. W. Wolterstorff. The right-hand figure 

 represents a male in breeding costume, the two others 

 are taken from females.
