118 ME. E. m'LACHLAN ON THE INSECTA COLLECTED 



rina, L. A number of specimens from Discovery Bay (carcass of a 

 Musk-Ox, Hart) also belong to the same species ; they agree with 

 the specimens of P. cadaverina, Kirby, in the British Museum. 

 The same or a similar fly occurred at lat. 82° 30' and 82° 33' 

 {Feilden). 



Anthomtiid^. — From Dobbin Bay and Port Foulke, Aug. 14th 

 and July 28th, 1876 {Feilden), there are Anthomyice. An Antho- 

 myia is among the insects of Eoss's Expedition. 



MtrsciDJB AcALTPTEEA. — Specimens from Floeberg Beach, 

 July 26th, and smaller ones from Discovery Bay, may perhaps 

 belong to this group ; but in their present state I can say nothing 

 about them. Curtis described a Scatophaga apicalis from Boss's 

 Expedition. 



[The chitinous integuments of Dipterous insects were found in 

 the stomach oi Salmonidcs from a lake at 82° 40' {Feilden).'\ 



HEMIPTEEA. 



There are no true Hemiptera in the collection from north of 

 78°*. But the Anoplura, or true lice, which are generally con- 

 sidered as degraded forms of this order, are represented by the 

 "Walrus -parasite from Walrus Island {Feilden), described and 

 badly figured by Boheman as Hematopinus trichechi (from Spitz - 

 bergen) in the Ofvers Yet. Akad. Eorhandlingar, 1865, p. 577- 

 This Louse is found in the axillae and on other soft parts of the 

 skin of the Walrus (Tricheclms rosmarus). 



MALLOPHAGA.

Four examples, on its host Nyctea scandiaca, from lat. 82° 30' 

 {Feilden). 



DocoPHORUs, sp. ?

NiEMUs ciNGULATUs {BuTwieister), Nitzsch. 

 Three examples on Tringa camotus, from lat. 82° 29', August

* From Disco Mr. Hart brought several examples of the $ of Dorthesia chiton, 

 Zetterstedt {Coccidce), already recorded from Greenland.
