4th segments each with a shghtly arcuate yellowish band, 

 einargiuate in middle on hinder side, placed just before middle ot'

This species might possibly be referred to Xantliogramma, as 

 the side margins of the thoracic dorsum are distinctlv though 

 rather narrowly yellow. Yet the abdomen has not the flattened 

 form characteristic of that genus nor is it at all raarginate. The 

 distinct yellow spots on the pleura are characteristic of Xantho- 

 granima, but the whole facies of the insect is that of Syrphus.
