A NEW NORTH AMERICAN BIRD-FLEA 



By F. G. A, M. Smit^ 



Dr. Phyllis T. Johnson, of the Entomology Research Division, U. S. 

 Department of Agriculture, Washington D. C, most kindly invited 

 me to describe a new bird-flea, material of which was found in the 

 collections of the U. S. National Museum. The specimens of the new 

 flea were collected from the nest of a barn swallow and are part of a 

 series which constitutes the first record of fleas from the North Amer- 

 ican subspecies of this host. It is a subspecies of Ceratophyllus affinis 

 Nordberg, 1935, and the host record is a valuable indication as 

 regards the true host of the little-known nominate subspecies. 



I am much indebted to the authorities of the U. S. National Museum 

 for the donation of one pair of paratypes of the new flea to the British 

 Museum collection of fleas at Tring.
