This group is without doubt the largest and most widely distributed of any in 

 the family Figitidae, the genera and species being exceedingly numerous although 

 but little studied. As soon as the attention of entomologists is directed to the 

 collecting of these obscure wasps and especially in tropical countries we may 

 expect the discovery of many new genera, as is clearly shown by the new genera 

 described here, most of which were recognized in a small collection of these 

 insects taken by Mr. Herbert H. Smith in South America. 



The subfamily is at once recognized by the cup-like elevation on the scutellum 

 and by the hind tibiae having two apical spurs, characters not found in any other 

 group.
