Lipeurus protervus Kellogg. 



A female of this curious species, taken on Larjofms lagopus, 

 Norton Sound. 



Lipeurus parviceps Piaget. 



Two specimens referable to this species from the eider 

 duck, Arctonetta fischeri. Duck Egg- Island. Lipeurus pari'i- 

 f cps has been recorded hitherto only from Sterna. Our spec- 

 imens differ from Piaget's figure, in having larger pustules in 

 the dorsal blotches, and only one dark spot on the metathor- 

 acic margin. Probably our specimens should be considered 

 to be a variety. 



Colpocephalum morsitans sp. nov. (Fig. :0. 

 One male from Triuga nwculata, Norton Sound. This 

 species is close to bicolor of Piaget from Strcpsilas interferes. 

 It can be distinguished from that species by the abdominal
