 The sessile abdomen and the greatly swollen and usually dentate or serrate hind 



femora, as in the Chalcididie, distinguish the family. It is not represented in 

 Europe and has reached its greatest development in South America and Australia, 

 where the species are evidently numerous. 1 have also seen an undescribed species 

 from Africa, where it should be well represented.
