296 Tachinidae. 



The species are parasitic on Rhopalocera and Heterocera, nigripes 

 also on Tenthredinids. The species, the biology of which is hest 

 known, is nigripes, it is very polyphagous and belongs to Pantel's 

 group 7, the ventral saw being used for wounding by the depositing 

 of the eggs in the host larvæ. 



About a dozen European species are known; 4 have been found 

 in Denmark.
