Subfamily ELAMPINAE 



These predominantly small wasps are parasites of soUtarj' ground- and wood-nesting wasps 

 and bees. 



Genus OMALUS Panzer 



Most of these species parasitize twig-nesting wasps although one has been reared from a 

 ground-nesting species. Authenticated host records all pertain to aphid-storing pemphredonine 

 wasps. European records of other wasps and bees as hosts of Omalus are probably erroneous 

 and based on mixed nests where supersedure by or of the pemphredonine had occurred.
