The two females taken at flowers of Pastinaca sativa by H. E. Evans 

 at Ithaca, N. Y., July 6, 1947, are accompanied by the note that 

 these and a few other specimens were walking along the stems just 

 below the umbels, holding the wings more or less erect, and fanning 

 them. They looked much like otitid flies, the bands on the wings 

 increasing the resemblance. 



This subspecies occurs in the Carolinian fauna and the warmer 

 parts of the Alleghenian fauna. Its usual habitat seems to be dry 

 deciduous woods where the females may be found running along the 

 twigs and small branches of shi-ubs and understory trees. In appear- 

 ance, habitat, and manner of walking they look much like certain 

 species of Camponotus (Formicidae) .
