Remarks: The expanded male fore and middle tarsi, the somewhat 

 elaborate modification of the male sixth abdominal sternum, and the 

 form of the male genitalia readily separate P. marginata from all 

 other known species of the genus Pseudozonitis; on the basis of these 

 characters, a separate species group should be established for it. 

 With respect to the male genitalia, P. marginata most closely re- 

 sembles a male Pseudozonitis collected by one of us (Selander) in 

 Oaxaca in 1955 and tentatively identified by us as P. megalops (Cham- 

 pion), a Central American form originally described from Guatemala. 

 Except for the absence of the unusual sexual modifications noted
