may be the same as Culex caspius, Pallas, as identified by Curtis 

 in the Insects of Boss's Voyage (p. Isxvi). Schiodte identifies 

 the same species with C. nigripes, Zett. ; the latter, according to 

 Sti»ger, also occurs in Grreenland, and is the same as C. pipiens, 

 O. Fabricius, nee Linne (Fn. Grcenl. p. 209). There are also 

 larvae and pupae in the collection {Hart). 



Chironomus is represented by several species, and seems to be 

 of common occurrence. The largest species, from lat. 82° 30', 

 July 1876 {Feilden), is apparently C. polaris, Kirby, Suppl. to 

 Appendix of Parry's First Yoyage; also in Curtis's Insects of 

 Eoss's Yoyage, p. Ixxvii, pi. A. figs. 2 & 14. The same or a 

 similar black Chironomus frequently occurs in temperate latitudes 

 in vrinter or early spring. A small species occurred near Cape 

 Hilgard (Aug. 14th, 1875, Feilden) ; the same or a similar species 

 lat. 82° 33', July 25th, 1876 (Feilden). From Floe-berg Beach, 

 lat. 82° 27', July 1876 (Feilden), there are two or three species, 

 large and small ; the large one appears to be different from C. 

 polaris. There are also Chironomi from Dobbin Bay, Aug. 14tb, 



1875 (Feilden). Likewise larvae of the genus (Feilden Sf Hart) . 

 Sciara. — A single example of this genus from lat. 82° 30', July 



1876 (Feilden), a S with very large forceps. 



TricJiocera. — Apparently the common T. regelationis, L. Its 

 occurrence in Grreenland is mentioned in Stseger's ' Groenl. An- 

 tliater.' I find it from Cape Hilgard, Aug. 14th, 1875, lat.82° 30', 

 July 1875 ; Floeberg Beach, lat. 82° 27', July 1876, lat. 82° 30', 

 July 1876 ; and Dobbin Bay, Aug. 34th, 1875. All these are from 

 Capt. Feilden ; but larvae we're also taken by Mr, Hart. In tem- 

 perate climates Trichocera occurs late in autumn, in winter, and 

 in early spring ; the occurrence of T. regelationis in July and 

 August well characterizes the climate in which they were taken. 

 . Tipula arctica, Curtis. — Several of this were taken by both 

 Capt. Feilden and Mr. Hart. 



Tachinid^. — A species hatched from cocoon oiDasychira groen- 

 landica, Dumb-bell Bay, July 15th, 1876 (Feilden), also from 

 another cocoon of the same Moth, Point Foulke, July 28th, 1875 

 (Feilden). Two larger Flies from Discovery Bay, Aug. 15th, 1876, 

 seem likewise to belong to this family. Among the Insects of 

 Eoss's Yoyage described by Curtis there is a Tachina Mrta. 



MusciD^. — From lat. 82° 27' (Feilden) is a Fly collected round 

 ofial, that may be Pyrellia cadaverina, Kirby, Faun. Bor.-Amer. 

 p. 316 (from lat. 65°). Kirby said it was very near P. cadave-
