The families Diapriidae , Beh/tidae, and Procfotry^ndae,'- 

 with additions to the Cerapliro7iid(te and Scelio7iidae. 



Family PROCTOTRYPIDAE. 



The old name is used, for the present, instead of Serphidae. 

 The Australian representatives of the family do not appear 

 to be numerous, as rather extensive collections made by the

 represented by seven specimens. One remarkable and distinct 

 new genus is described, but the other new species fall into well- 

 known genera.
