Mallophaga 5d 



Genus Lipeurus. 

 Lipeurus protervus Kellogg. 



New Mallophaga, III, 1899, p. 31, PL III, f. 4. 



Many specimens, males and females, from Rock Ptarmigan, Lagopus rupestris 

 (Gmel.), taken at Bernard harbour, Northwest Territories, in November, 1915, 

 and May, 1916, and at Demarcation point, Alaska, in May, 1914; and from 

 Willow Ptarmigan, Lagopus lagopus (Linn.), taken at Bfernard harbour, in 

 February, 1915, and March, 1915, and at Demarcation point, Alaska, in May, 

 1914. 



Also several males and one female from a Lapland Longspur, Calcanus 

 lapponicus (Linn.), taken at Demarcation point, Alaska, in May, 1914. Since 

 the species is typically a parasite of grouse, one is led to question the 

 authenticity of this record. 



Recorded by Kellogg, and Kellogg and Kuwana from Lagopus lagopus from 

 Alaska. 



From a comparison of the expedition specimens with the descriptions of 

 European writers, I am led to the conclusion that L. protervus is closely related 

 to, if not identical with, the Nirmus quadrulatus of Nitzsch. This species, 

 which Harrison looks on as a synonym of Degeeriella camerata Nitzsch., has 

 been recorded by a number of European writers from various species of Tetrao 

 and Lagopus. 



Genus Philopterus. 



Philopterus ceblebrachys Nitzsch. 



In Denny, Anoplur. Brit., 1842, p. 92, PI. I, f. 3. 



Numerous specimens, males and females, from Snowy Owl, Nyctea nydea 

 (Linn.), taken at Barter island, Alaska, in June, 1914. 



Recorded by Kellogg from the same host taken at point Barrow, Alaska. 



I have numerous specimens of this species from the same host taken in 

 Ontario. These specimens are uniformly paler and stouter, and the clypeal front 

 more broadly truncate than the expedition specimens. The latter approach 

 more nearly to the descriptions and dimensions given by European writers, 

 especially Piaget, than do my southern specimens. It is doubtful, however, if 

 the two can be separated. 



Philopterus cursor Nitzsch. 

 In Burmeister Handbuch II, 1838, p. 426. 



Mature male and female and numerous immature specimens of both sexes 

 from Short-eared Owl, Asio flammeus (Pontoppidan), A. acdpitrinus (Pall.), 

 taken at Barter island, Alaska, and Demarcation point, Alaska, in May, 1914. 



Recorded by Kellogg from the same host taken at point Barrow, Alaska. 



Philopterus dentatus Scopoli. 



Ent. Cam. 1763, p. 383. 



One female from a Hutchin's Goose, Branta canadensis hutchinsi 

 (Richardson), taken at Bernard harbour. Northwest Territories, in June, 1915. 



Recorded by European and American writers (P icterodes) from various 

 species of ducks and geese; by Kellogg from Merganser serrator Linn., taken 

 at Kodiak island, Alaska.
