vision of Chalcidodea. The family Pteromalidae consists of two sub- 

 families Metasteninae and Pteromalinae. Subfam. Sphegigasterinae. 

 Spalangiinae and Diparinae I am inclined to put together with subfam. 

 Miscogasterinae into the fam. Miscogasferidae. Subfam. Euuotinae must 

 be combined with subfam. Tridyminae into the fam. Tridymidae. To 

 the last one belongs also Ashmead's tribe Isoplatini.
