192 DIPTEROUS GENUS DIAPHORUS 



Described from one male and two females taken at Braden- 

 town, Fla., in March; one male taken by Dr. J. C. Bradley at 

 Lavender, Floyd County, Ga., August 23d, has slight indications 

 of a central vitta on the dorsum of the thorax ; while one taken 

 by Mr. Nathan Banks at Chain Bridge, Va., on September 17th, 

 has a sharply defined vitta ; one male which I took at North 

 Evans, Erie County, N. Y., August 16th, differs from the others 

 in having the pulvilli slightly more developed. Type in the 

 author's collection.

I do not think this species has been recognized since 

 described ; it differs from variabilis ri.-sp. by having the eyes nar- 

 rowly separated.
