Translator's Explanatory Notes. 



The translation of this work was not started at the beginning, as 

 it was not at first decided that the entire book should be translated. 

 And unfortunately I did not thoroughly look into the Introduction in 

 front of the book. This is responsible for some errors occurring in 

 the translation of the second group Tachyporini , which was done first, 

 also in the third group Staphylinini , which came next, from there to 

 the end of the book no such errors occur, and the first group Aleocha- 

 rini , which came last is doubtless the best translation, as the struc- 

 ture of the insects, and the most generally applied technical terms 

 became more familiar to me, as the work progressed. . 



The author has used strichtly Danish terms throughout the entire 

 work, and I naturally followed his form of expression as much as pos- 

 sible, however endeavoring to find the best English terms; therefore 

 when he speaks of .the fore- middle- and hind-breast, I naturally trans- 

 lated it as presternum etc., the Introduction however shows that it 

 should have been - prothorax- etc., when referrin'? to the breast, the 

 term breastbone is applied: fore-breastbone etc. - For the literal 

 term "forebody" T have formerly used; thorax, but was lately told that 

 in coleoptera the terra forebody is more explicit, so I have used this 

 term in the latter part of the work.
