of all others. From this same host half a dozen spec- 

 ies of Docophorus (all of the i^^^^^y^^^'^^^'^^ ^JP^) have 

 been described. 



The truncate, not emarginated, clypeal front, and the 

 slight dilation of the uncolored part of the clypeus 

 lead us to refer our specimens to a species proposed by 

 Giebel for specimens collected from the same host as 

 that of our specimens. Osborn (Insects Affecting 

 Domestic Animals, 1896, p. 218,) describes a species 

 halieti from the Bald Eagle, Haliceetus leucocephalus 

 (Florida). This species has a marked lateral, anterior, 

 clypeal dilation, and the front is emarginate. 



The members of the group may be recognized by the 

 uncolored front of the clypeus more or less dilated. 

 We figure a female. Measurements: Male, body, 

 length 2.22 mm., width 1.2 mm.; head, length .85 

 mm., width .91 mm. Female, body, length 2.81 mm., 

 width 1.4 mm.; head, length .94 mm., width 1. mm.

 Specimens from two individuals of the American 

 Long-eared Owl, Asio ivilsonianus, (Ontario, Califor-

 ianus (Lawrence, Kansas). Recorded by Osborn from 

 Asio ivilsonianus (Ames, Iowa, and Lincoln, Nebraska).
