TWO NEW GENERA IN PSAMMOCHARID2E (HYM.) 
By Nathan Banks 
Museum of Comparative Zoology, Cambridge, Mass. 
Pompilus nobilis Fab. exhibits an interesting assembly of 
characters which tend to lessen the differences between the sub- 
families of these wasps. The general structure and venation is 
much as in the Pseudageninae but there is no true petiole. 
Priochilus gen. nov. 
The attachment of abdomen to propodeum simply tapers to 
the base, no petiole. The claws are cleft, there is a median row 
of spines on under side of last joint of hind tarsus, the hind 
femora have a few minute spine-pits on upper side near tip; 
there is no distinct pocket in the third discoidal cell, and no 
groove on second ventral segment; spines above on hind tibiae 
are rather long and not in rows. Genotype, Pompilus nobilis 
Fabricius. There are various other species in South America. 
Priophanes gen. nov. 
This is based on species formerly placed in Priocnemis which 
have a petiole, or hour-glass shaped attachment, of abdomen 
to propodeum, and thus goes into the Pseudageninae. The hind 
tibiae have rows of spines above, and distinct teeth at least on 
basal part. The venation is much like Pseudagenia; claws 
toothed; no beard under head; venter of female with a groove 
across second segment; mesosternum not prominent laterally. 
Genotype, Priocnemis jacetus Cresson. Various other species in 
North and South America.
