to the Alps; if it is certaln that it is included in Fallen's nigripes, it 

 goes towards the north into Sweden. 



Remarivs : I have for both the preceding species quoted D. nigripes 

 Stæg. p. p. and for the following reasons: Loew (1. c. V) says, that 

 three pairs sent to him from Stæger were Meigenii; Schiner on the 

 contrary states, that he has had specimens from Stæger, which were 

 Falleni. In Stæger's coliection also both species stood under nigripes, 

 so that it is evident, that he had mixed the two species. Loew is of 

 opinion, that Stæger's description is based on Meigenii, in this I cannot 

 agree; on the contrary Stæger's expression about the last joint of the 

 front tarsi in the male seems to me to indicate without doubt, that 

 he has had Falleni to hånd.

 curved hairs, the ventral margin with dense, short hairs. Legs black; 

 coxæ grey, front coxæ whitish grey pruinose anteriorly; knees very 

 narrowly reddish; the last joint of the front tarsi dilated, but it is 

 compressed, not flattened as in Falleni. The anterior coxæ with
