 much shorter lobe, or an obtuse-angular or tooth-formed process, 

 provided with a very Ions bristle-hair; on ventral side the first 

 ventral joint of same sex has at base a short carina, the fifth 

 more or less emarginate, the sixth very deeply cleft into two horn- 

 formed and slightly curved parts. The sixth free dorsal joint of ^ 

 is either divided into four long tips, or in two long, bristle- 

 bearing side-lobes and a broad middle-lobe, which may be undivid- 

 ed broad-tipped, or with a deep incision divided into two narrow 

 teeth; the sixth ventral ^oint is divided into six lobes, of which 

 the two middle-ones are broadest, with convex tip and with fine 

 unci in tip, the others narrow, styliform and with a very long 



bristle-hair at tip. 



The species Tachinus is found particularly at decaying plant- 

 matter, carion and manure, also at outflowing tree-juices. About 

 a score of species are distributed in Middle- and North-Burope, and 

 of these, 11 are heretofore found in Denmark. An other couple from 

 the nearest neighbouring countries are encluded in the following.
