Nirmus euprepes Kellogg and Chapman. 

 Male and female from Arenaria melanocephala, San Martin 



Island. 



Nirmus caracarensis n. sp. 



Three males from a caracara, Polybonts Icntosiis, Guade- 

 loupe Island. This specimen most closely approaches N. splen- 

 di<1its Kellogg, but differs in the much smaller size, the broadly 

 rounded clypeus, and the markings. It is perhaps related both 

 to splendidus and to N. discocephalus Nitzsch, and the three 

 species form a group distinguished by the broad abdomen and 

 n innded head. The three species infect raptorial birds. Splen- 

 didus was found on Polyborus cherhvay.
