pepsinae: tribe macromeresti 177 



phanes comes Banks 1946, Priophanes pictipennis Banks 1946, and 

 Priophanes rufigaster Banks 1946. The Neotropic species have not 

 previously been referred to Ageniella and the first two hsted have not 

 previously been placed in Priophanes. Ameragenia adele Banks 1946 

 probably belongs here, but the type lacks the abdomen and hind 

 tibiae and so is diflBcult to classify. Bradley (1944, Notulae Naturae, 

 No. 145, p. 6) places Pompilus (Priocnemis) sartorianus Cresson 1867 

 in Priophanes. I have studied the t^^pe of sartorianus and though it is 

 a member of the Macromerini with teeth on the outside of the hind 

 tibia, it disagrees in several characters with Priophanes as defined 

 here.
