SYNOPSIS 

 A new key to the families of Chalcidoidea is presented so as to facilitate recognition of 

 Pteromalidae, the limits of which are difficult to define succinctly. The main part of the work 

 deals with Pteromalidae ; this family is keyed to species level in all except a few genera which 

 need further study. Full synonymy is given, as far as possible, at all levels. The distribution, 

 and where known the biology, of each species is indicated. More than 800 species are dealt 

 with ; 4 new genera and 87 new species are described. The work is based mainly on a critical 

 study of type-material ; almost all (663) of the types of Palaearctic Pteromalidae in the British 

 Museum (Nat. Hist.), and also about 300 types in other important European collections, were 

 examined.
