Mallophaga 5 D 



Genus Lipeurus. 

 Lipeurus protervus Kellogg. 



New Mallophaga, III, 1899, p. 31, PI. Ill, f. 4. 



Many specimens, males and females, from Rock Ptarmigan, /,////<;/,//> nq 

 (Gmel.), taken at Bernard harbour, Northwest Territories, in November, I'.ii:., 

 and May, 1916, and at Demarcation point, Alaska, in May, 1911: an. I tK.in 

 Willow Ptarmigan, Lagopus lagopus (Linn.), taken at Bernard 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, ('ul, 

 lapponicus (Linn.), taken at Demarcation point, Alaska, in May, 1!M 1. Sin<-- 

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

 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 description- of 

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

 to, if not identical with, the Nirmus quadrulatus of Nit/sch. 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 Tctmn 

 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 nyctea 

 (Linn.), taken at Barter inland, 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.
