OOLLEMBOLA AND THYSAIfURA, 



found in scotland in the summer of 1876. 



By LINA and O. M. REUTER. 



DURING the tour I made with my wife in Scotland, we 

 turned our attention partly to the Collojibola and TJiysan- 

 ura of the country. An account of our findings may perhaps not 

 be without interest, the localities visited by us not having been 

 previously investigated regarding these animals. Besides, the 

 distribution of this order in Britain is as yet very little known. 



Our excursions comprehended the Shetland and Orkney 

 Islands (in the month of July), Morayshire (Forres, Dava, and 

 other localities during the end of July and August), and Perth. 

 The collections from the last place have unfortunately been so 

 much destroyed, that only one species could be surely deter- 

 mined. This species seems to me to be new. 



From Shetland we brought home seven species of Collembola 

 and one of Thysanura. If we examine the Collembolas, we will 

 find that only one of them {Degeeria cindd) is not as yet found 

 in Scandinavia ; while not less than four {Smmthu7'us I'mcatus^ 

 Macrotoma vulgaris^ Isotoina crasskauda, and Achoruies viaiicus) 

 have not been previously recorded as British. Of the seven 

 species, Smiiithuriis Imeattis was found in peaty places, where- 

 from the peat was scaled, and where it was very difficult to find 

 because of its likeness in colour to the ground; the Macrotoma 

 and Isotoma pahistris were more or less common and numerous 

 under rotting wrack [Fuais) on the sea-shore; Dcgceria cinda was 

 found under stones ; Isotojua crassicauda and Achoruies viaticus 

 in large numbers in wet places. 



In Orkney we found thirteen species, of which one seems not 

 to have been described before. With the exception of the 

 Macrotoma. and Isotoma crassicauda^ here were met all those
