Chrysotoxum fasciolatum De Geer. 



The largest and most common species in northern New Eng- 

 land, usually about 14 mm. in length. Readily separated from 

 Chrysotoxum perplexum by its shorter first antennal joint and 

 broader, less arcuate abdominal fasciae, the front edge of the 

 interrupted fasciae being almost parallel with the anterior 

 margins of the segments.
