Our knowledge of the British Tachinidae from the Fen 

 District is at present so unsatisfactory that no record of any 

 important species can be included here, but it is highly 

 probable that the Fens with their many rare Lepidoptera 

 would be certain to provide a few rare species of Tachinidae.

 occurring in this district of Cambridgeshire: Hyetodesia ob- 

 scurata, Mg., and H. umbratica, Mg., Alloeostylus flaveola,
