1. Mallophaga of North American Birds. 



By Vernon L. Kellogg, Stanford University, California. 



eingeg. 25. Januar 1896. 



Thespecies oî Mallophaga described byDenny,Nitzsch, Giebel 

 and Piaget in their monographs are based on specimens taken almost 

 exclusively from birds of the Old World. No recognizable species of 

 Mallophaga has been described from specimens taken from North 

 American birds. An American entomologist, Prof. Herbert Osborn, 

 has identified on birds taken in North America 15 species of Mallo- 

 phaga originally discovered on European bird specimens; of these 

 15 species, 4 are from birds M^hich may be called domestic fowl and 

 are specifically identical with the European birds from which the 

 same species of Mallophaga were taken. 



As a result of a recent examination of a collection of Mallophaga 

 made by me from North American water and shore birds, mostly 

 maritime birds shot on the Bay of Monterey, California, I have de- 

 scribed one new genus and 38 new species, and identified 23 species 

 of Mallophaga originally described from Old World birds. In addition, 

 of 40 species taken from American land birds, I have been able to 

 refer 16 to already described forms, the remaining 24 being new. In 

 almost all cases where already known species were found, the parasites 

 have either been on birds identical in species with the Old World
