Exorista. 321 



not broad, bliiish white priiinose band, a little shifting according to 

 view; about tbe hinder half of the segments and a middle line black 

 and shining. Abdomen black-haired, with discai and marginal bristles, 

 of the latter a pair on second and third segment and a row on fourth ; 

 of discai bristles one or more pairs on third and fourth segment. 

 Legs black; hind tibiæ with an anterodorsal row of unequal bristles 

 with a long bristle in the middle; claws and pulvilli strongly elongated. 

 Wings brownish yellow at base and anterior margin, outwards almost 

 clear; veins brown; first posterior cell ending a little before apex of 

 wing; discai angle obtuse and a little rounded; apical cross- vein 

 rather sloping and straight or slightly and evenly curved; posterior 

 cross-vein a little doubly curved. Squamulæ white. Halteres yellowish 

 brown. 



Female. Similar; frons above fully as broad as the eye; antennæ 

 with third joint relatively shorter. 



Length. Rather varying, 5,5 to about 10 mm. 



E. mitis is rare in Denmark, only four specimens are known, two 

 males and two females; Ordrup Mose (Stæger); on Lolland in Døde- 

 mose near Nysted, and in Jutland at Silkeborg and Funder (Esben- 

 Petersen); the dates are ^"/g — ^Z,. 



Geographical distribution: — Europe down into France; towards 

 the north to northern Sweden. 



Remarks: Two of our specimens are from Stæger and were 

 determined linearicornis Zett., one was the present species, the other 

 Westermanni, and even if Zetterstedt had not seen these specimens I 

 think it beyond doubt that his linearicornis is identical with mitis.
