84 Psyche [April 



Ruffed Grouse (Bonassa umbellus). Liberty Hill, Conn., Oct. 

 1896 (O. Bangs). 



Olfersia sp. 



From Chuck-wills- widow (Antrostomus carolinensis) , St. 

 Augustine, Fla. (C. W. J.). 



Ornithoctona erythrocephala (Leach) 

 This has been found on the following species of birds: 



Red-tailed Hawk (Buteo borealis). Cuba (M. C. Z.). 

 Broad-winged Hawk (Buteo platypterus) . Cuba (M. C. Z.). 

 Sparrow Hawk {Falco sparverius). Porto Rico (Coquillett). 

 Ruddy Quail-dove (Geotrygon montana). Holguin, Cuba (M. C. 



Z.). 



Yellow-crowned Night Heron (Nyctanassa violacea). Dominica, 



May 25,'01 (0. Bangs). 

 Pigeon Hawk (Falco columharius) . Metis, Quebec, collected 



by L. M. Terrill. 



The last record, received through Mr. Albert F. Winn, is 

 especially interesting. Although Osten Sacken recorded this 

 fly from Quebec, this is the first record of a host north of the 

 West Indies. Mr. Terrill captured the hawk on her nest and 

 seven specimens of the fly were taken. Since writing the above 

 Jos. Ouellet informs me that he has taken this species on the 

 American Bittern, near Montreal, Aug. 1902. 



Pseudolfersia fumipennis (Sahlberg) 

 (P. maculata Coquillett). 



From the Fish Hawk or Osprey (Pandion halicetus carolinen- 

 sis). Cape May, N. J., Aug.; Lahaway, N. J., Apr. 1 (J. T. 

 Brakeley); St. Augustine, Fla. (C. W. J.); Sand Point, La., 

 and Cuba (Mus. Comp. ZooL); Bald Eagle (Haliaeetus leucoce- 

 phala). Hampton, N. H., May 17, '05 (S. A. Shaw); and Loon 

 (Gavia immer) . Wisconsin (Coquillett).
