comparison with the British Lepidopterou-Fauna alone, though 

 they deserve, I believe, a wider treatment. Since, besides, English 

 Entomological Journals, such as the Entomologist, are not accessible 

 to every German entomologist, the following treatise by me upon 

 the subject may not be considered superfluous. 



I have subjoined notices to my work with regard to the geographi- 

 cal and vertical range of the species in question. I intend by this 

 less to state where especially any species occurs, because the work 

 of the brothers Speyer, 2 he Geographical Range of Butterflies, as 

 well as the catalogue by Staudinger and Wocke, gives thorough 

 information upon that point, than to determine which of the 

 species in question reaches its greatest diffusion under the same 

 or similar conditions of climate as those in which they occur 

 in the far North, and in the higher mountain regions; and 

 upon this point, at the conclusion, I will give a tabulated 

 synopsis. 



For this purpose I have made use of the following works : —

Zeitung, 1857.

 and also of information kindly communicated to me by letter by 

 Dr. M. Standfuss, Parchwitz, upon the occurrence of the species in 

 the higher parts of the Silesian Mountains (from about 4000 feet 

 upwards). 



The remarks bearing upon the Upper Harz Mountains are the
