Subfamily NYSSONINAE 



The wasps of this subfamily are cleptoparasites in the nests of other ground-nesting aculeates. 

 The more primitive genera have as their hosts wasps belonging to the closely allied Gorytinae. 

 Two of the more highly specialized genera appear to have as hosts Larrinae (Larridae) and Cer- 

 cerinae (Philanthidae), and a third may have an andrenid bee as its host.
