Culicidæ. 



1. Culex nigripes Zett. 



Common on the East coast; Hekla Havn 15.-19.7.92; 

 Rode Ö 17.8.92 and Jameson Land 3.8.91. 



Geographical distribution: A widely distributed arctic 

 species; as to the supposed occurrence of this species in 

 Denmark I refer to Lundbeck (9. 1898. p. 296). 



Empidæ. 



1. Bhamphomyia nigrita Zett. 



Hekla Havn 19. 6. 92; 19. 7. 92; August 91 Hold with Hope, 

 a moderatly large series. 



Geographical distribution: Only known from Green- 

 land. Of recent years, this species has only been found north 

 of 68° N. Lundbeck, however, takes Otto Fabricius' species 

 Emjpis borealis to be identical with R. nigrita in which case 

 it is also found in South-Greenland. 



2. R. hirtula Zett. 



Hekla Havn 15. 7.— 8. 91 and Hold with Hope. 



Apparently as common as the foregoing. 



Geographical distribution: Only known from Green- 

 land, where it is quite common on the West coast from the 

 southern point up to 70° N. 



Dolicliopodidæ. 



I. Dolichopus groenlandicus Zett. 

 ïasiusak 8. 98. 2 specimens. 



Geographical distribution: Only known from Green- 

 land. Common on the West coast. 



Syrphidæ. 

 1. Melanostoma ambigua Fall. 

 Кар Stewart 5.8.91; Gaaseland 12.7.92. 

 Two badly preserved specimens, as previously determined 

 by Lundbeck (4. 112), belong most probably to this species.
