Chironoiiuis j)of(fr/,<, Kivhj (and about three other species). 



Sciara sp. ?

Anthomyia sp. ? 



Scatophaga sp. ? 



Among the Diptera there is nothing- of any special im- 

 portance. The most striking is a ' daddy-long-legs ' (Tipida 

 arctica), well known as an Arctic species. Of the others 

 there are Ctdicidce (gnats), Trichocera, ('winter-gnat,' but 

 appearing there after midsummer), Chironomi (plume gnats), 

 and familiar-looking flies which appeared when offal was 

 thrown away, or the carcase of an animal lay on the ground. 



Hemiptera (Anoplura). 



Hematopinus trichechi, Boheman. 



The only so-called Hemipterous insect is a louse (Hema- 

 topinus trichechi) that infests the walrus ; found in the 

 axillae and other parts where the skin is soft. This was 

 originally described from Spitsbergen. 



Mallophaga. 



Docop/torus ceblebrachys, Nitzsch (and two others). 

 Kirmus cingulatus, Burm. 



„ phceonotus, Nitzsch. 

 Colpocephalwnij sp. ? 

 Menopon gonophceum, Burm. var. ? 



The Mallophaga (bird-lice) are rather numerous in 

 individuals, some of them probably new species, others already 

 familiar. These of course are carried hither and thither by 

 their hosts.
