I am still uncertain of the identity and limits of this fly and am 

 inclined to consider it as being identical with gihljosa. The specimens 

 mentioned by Osten Sacken from Va. and Ohio seem certainly to per- 

 tain to gihhosa. The species, fvliginosa^ gihhosa and tristls are very 

 clo.sely related.
