The female of hetarum agrees in every particular with that of the writer's 

 specimen of suhstriata, both series showing a variation in the develop- 

 ment of the presutural acrostical bristles which makes it difficult to dis- 

 tinguish them from the female of fugax. 



Stein (1919) lists suhstriata as a synonym of fugax, with a question mark.

The females of Hylemyia hrassicae that have been collected in the woods 

 appear to differ in color from those reared or collected around vegetable 

 fields. The former are almost bluish or steel gray in shade, and the thorax 

 is distinctly marked by brownish vittae. The specimens collected around 

 vegetable fields are cinereous in shade, with brownish markings on the 

 thorax.
