MR. R. 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). 



Anthomyiid^. — Erom Dobbin Bay and Port Eoulke, Aug. 14th 

 and July 28th, 1876 (JTeilden), there are Anthomyice. An Antko- 

 myia is among the insects of Eoss's Expedition. 



MusciDiE AcALTPTERA. — Specimens from Eloeberg 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 E-oss'a 

 Expedition, 



[The chitinous integuments of Dipterous insects were found in 

 the stomach of Salmonidce from a lake at 82° 40' {Feilden).'] 



HEMIPTEEA. 



There are no true Hemiptera in the collection from north of 

 78°*. But the Anojplura, 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 tricheclii (from Spitz- 

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

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

 skin of the Walrus {Tricliechus rosmarus). 



MALLOPHAGA. 



DOCOPHORUS CEBLEBRACHSS, NltZSeJl. 



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

 {Feilden). 



DoCOPHORUS, sp. ? 



One example on Tetrao rupestr is, from lat. 82° 45' {Feilden). 

 DoCOPHORUS, sp. ? 



One example on Bernicla hrenta, from lat. 82° 33', 24th June, 

 1876 {Feilden). 



NiRMUS ciNGULATUs {B urmeister) , Nitzsch. 

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

 8th, 1876 {Feilden), appear to accord with the published descrip- 



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

 Zetterstedt {Coccidcs), already recorded from Greenland.
