THE BRITISH NATURALIST. 



[August 



The noise produced during flight can also be produced when not 

 in motion ; on removing the lid of the box on the following morning 

 to make a closer inspection of the first capture, I was rather sur- 

 prised to find it was able to make a humming noise when annoyed, 

 a beautiful undulating sound, it was some time before I could discover 

 how it was produced, seeing the fly apparently did not move, at last 

 with a powerful lens I discovered that it was by its poisers vibrating, 

 and I believe coming in contact with some short bristly hairs situated 

 on the abdomen and pointing towards the thorax ; the undulations were 

 caused by the rapidity with which the poisers were moved.

HYPODERMA Bovis, Dcg. — This spccics which was identified by 

 Mr. C. Matthews was captured on the 9th June, on the moor between 

 Yelverton and Clearbrook, the hairy body in three colours, white, 

 black, and red, giving it a very bee-like appearance. This is a 

 subcutaneous parasite on cattle, and very seldom taken in the imago 

 state. — Id.
