Nirmus fuscus Nit/.sch. (See Kellogg, New Mallophaga, 

 ii, 1800, p. 400, pi. Ixvii, fig. 7). 



Specimens from the Western Goshawk, Accipiter 

 aii'icapillus striatiUus (Pullman, Washington), the Des- 

 ert Sparrow Hawk, Falco sparveriiis deserticolas (Palo 

 Alto, California), the Western Red-tailed Hawk, Buteu 

 borealis caliirus (Palo Alto, California), and the White- 

 tailed Kite, Eianus leucurus (Palo Alto, California). 

 Taken previously by Kellogg from Buteo sicainsoni, Cir- 

 cus hudsoniiis and Archibuteo lagopus sandi-johannis , all 

 from Lawrence, Kansas. Recorded by Osborn from 

 Buteo sicainsoni (Ames, Iowa), and from Accipiter velox 

 (locality?). 



These specimens combine characters o( fuscus, rufus, 

 et al. of Nitzsch, so as to lead us to doubt the distinct- 

 ness of these various species of Nitzsch. We have with 

 Nirmus fuscus, sens latus, of the hawks, a repetition of 

 the condition shown by Docophorus communis of the 

 passerine birds.
