 Gen. LiMNOBiA, Meigen. 



The following species, in the structure of the wing-veins, does not accord 

 with any of Meigen 's divisions of the genus. The mediastinal vein 

 ends at about three-fourths of the length of the wing; the subcostal 

 ends at seven-eighths of the length, and is connected with the radial 

 by a transverse veinlet at its tip ; the radial, the cubital, and the 1 st 

 and the 3rd externo-medial are long and of equal length ; the 2nd 

 externo-medial springs from the 1st, at one-fourth of its length; 

 the 3rd externo-medial is connected by a transverse veinlet near its 

 base with the subanal.
