SUMMARY. 



So far 282 species of Mallophaga have been recorded from North 

 American hosts, of which 264 species are from birds and 18 from mam- 

 mals. These species of Mallophaga represent IS out of the 21 recog- 

 nized genera. All of these genera except one {Giehelia) were estab- 

 lished for S])ecimens taken from European hosts. Of the 264 species of 

 Mallophaga from North American birds, 107 are species originally 

 described from European hosts (in 11 cases the American specimens 

 being called varieties). The remaining 157 species were described from 

 American hosts.
