156 THE SCOTTISH NATURALIST 



In Dr F. Buchanan White's Insecta Scotica, Scotland was 

 divided into thirteen natural districts, according to the main 

 river basins and islands, and it was on this method that the 

 distribution of species was indicated in the Coleoptera of 

 Scotland. In recent years, however, the tendency amongst 

 biologists in Britain has been to indicate distribution according 

 to the County and Vice-County divisions, as laid down by the 

 late Hewet C. Watson in his Cybele Britannica (1859) ; and in 

 particular several recent lists of Scottish insects have been 

 compiled in this manner. In the present paper, while it has 

 been thought advisable to adhere to the natural areas as 

 defined by Dr F. B. White, and adopted in the Coleoptera of 

 Scotland, the County or Vice-County in which the species 

 has occurred has also been indicated after the name of the 

 natural division. As Mr Wm. Evans points out in his paper 

 on the Ants of the Forth District {Scot. Nat., 1912, p. 105), 

 very often a County is partly in one natural division and 

 partly in another, and it must therefore be understood in 

 such cases that the part of the County which lies within the 

 natural division is referred to. The order in which the 

 natural divisions have been given is that contained in the 

 Coleoptera of Scotland. 



The records mentioned in this supplement extend from 

 the date of the commencement of the Coleoptera of Scotland 

 in 1 87 1 down to the end of 191 2, and every effort has been 

 made to avoid missing any additional record during that 

 period. The literature on Scottish Coleoptera, however, is 

 more voluminous than one would think, and is scattered 

 throughout many scientific publications, so it is therefore 

 quite possible that some records may have been overlooked. 

 The name of the recorder only is given, and the number, if 

 any, after the recorder's name has reference to the appended 

 bibliography, which contains a full list of the papers and 

 notes in which additional species have been mentioned. 

 Records which for one reason or another are considered 

 doubtful or requiring additional confirmation, are included 

 in square brackets. In this connection I may say that it 

 was considered more satisfactory to include all records and 

 indicate any that seemed doubtful, rather than omit the
