a generic or subgeneric sense was by Ashmead, 1899, who characterized it as a genus. 



The species nest in soil, and African forms have been reported to provision their nests with 

 ants. One species in North America and two species in Sri Lanka have been observed recently 

 preying upon Miridae, both nymphs and adults.
