abdomen inserted high up on the propodeum, like genera 
in the Evaniidae, and are for this reason referable to a sep- 
arate family. 
PSILOPARIA new genus. 
Presumably related to A pechoneura Kriechbaumer, of which 
it may prove to be a synonym but from which it appears to 
differ in its armed cheeks. Has also characters in common 
with Labena Cresson, Grotea Cresson, and Megarhyssa Ash- 
mead.

facial line : : 3 : 44; front mostly reddish, with an impression on each side
