 1873-1383). In generic and specific descriptions, I have, partly in agree- 

 ment with Thomson (Skandinaviens QoleopAera. 1859-1863), sought to reach 

 a sound basis for determinations by indicating all comparatively easily 

 seen characters and external marks. Detailed descriptions of finer and 

 concealed mouth-parts are as far as possible avoided, and only in difficult 

 cases e.g. the shape of the tongue is used as conclusive character in the 

 generic key. Generic and specific names are, with a few exceptions, in a- 

 greement with Catalogus Coleopt . "urop. Ed . IV. Edm. Reitter. 1891. Some 

 of our earlier applied names in the classification are thereby shifted over 

 to the series of synonyms. Of synonyms the most important generic and spe- 

 cific names are listed. 



Data concerning the natural range, occurrance, and other biological 

 circumstances etc. of the species, I have presented partly from personal 

 notes, partly according to reports or from findings in other collections, 

 and in entomological papers. As far as possible all sources of informa- 

 tion of any importance are listed in their proper places.- Inasmuch as 

 rove-beetles can be found and collected nearly all the year round, I have 

 ordinarily only denoted localities for especially rare species, in as far 

 as these have been known to me. 



The list of authors and their entomological works here cited, which is 

 found last in the book, will sufficiently explain abbreviations used for 

 names of authors, and writings cited. - The accentuation in the generic 

 and specific index is partly according to information most cordially ex-
