The Provisional Atlas for Odonata was published in 1978 and included all records received up to May 1977. By the end of 1978 so much additional information had been received that it was felt necessary to update the maps. This was carried out during the winter and early spring of 1979 and it was these maps that formed the basis of this session. I would like to express my sincere thanks to Bill and Bob Merritt who carried out the majority of the updating work and also to David Parker from whose notes much of this summary derives.
