vi. p. 547. There is no evidence of their being auditory organs. 
A. W. Bennett, J. Hort. Soc. (n. s.) iv. pt. 13, pp. 30-33, states that 
the stomachs of Eristalis tenax and Syrphus clypeatus have been found 
by him to contain large quantities of pollen grains, especially of compo- 
site plants. He quotes E. Miiller's belief that the transverse denticula- 
tions in the terminal valves of the proboscis are specially adapted for 
disintegrating these grains (c/. also Nature, vii. pp. 132 & 133). Obser- 
vations on Syrphidce seen feeding on pollen, by W. E. Hart, Nature, vii.
