A LIST OF FAMILIES AND SUBFAMILIES OF ICHNEU- 

 MON-FLIES OR THE SUPER-FAMILY ICHNEUMO- 

 NOIDEA (HYMENOPTERA). 



BY HENRY L. VIERECK. 



In the following list the supergeneric groups of the Ichneu- 

 monoidea are systematically arranged according to the writer's 

 latest views. To avoid confusion in referring to groups of 

 genera by word of mouth, all tribes are treated as subfamilies. 



Family Vipionidae Yiereck. 

 Subfamily Opiinae Cresson. 

 Subfamily Cardiochilinae Ashmead. 



(Cardiochiles Nees, etc.) 

 Subfamily Microgasterinae Cresson. 



(Microgaster Latreille, etc.) 

 Subfamily Mesocoelinae , new subfamily. 



( Mesocoelus Schnlz. ) 

 Subfamily Apantelinae, new subfamily. 



(Apanteles Foerster, etc.) 

 Subfamily Miracinae, new subfamily. 



(Mirax Haliday.) 

 Subfamily Elasmosominae, new subfamily. 



(Elasmosoma Ruthe, etc.) 

 Subfamily Adelinae, new subfamily. 



(Adelius Haliday, etc.) 

 Subfamily Vipioninae Gahan. 



( Vipio Latreille, etc. )* 

 Family Agriotypidae Haliday. 



(Agriotypus Walker. ) 

 Family Alysiidae Ashmead. 



* The length of thesubmedian cell is too unstable to warrant its use as a foundation 

 for groups of genera, hence Aphastobraconini and Euurobraconini are not adopted 

 here.
