Family LARRIDAE 



The contributions cited below treat only the subfamilies Larrinae and Miscophinae because 

 the Trypoxyloninae have been associated with the former two groups only since 1964. The revi- 

 sions are quite inadequate for identification in most genera for many additional species have 

 been described in intervening years.

Subfamily LARRINAE 



All of the American genera are ground-nesting but one extralimital genus is known to nest in 

 twigs. The North American species are reported to prey upon various kinds of Orthoptera. How- 

 ever, no prey preference has been reported for our single species of Prosopigastra; in Europe 

 some species of the genus prey upon Hemiptera and Homoptera. One extralimital genus preys 

 upon lepidopterous larvae.

 Only the typical subgenus occurs in North America. Larra preys upon mole crickets and 

 several extralimital species have been introduced into other areas for control of these pests.
