Mr. Bruce adds that this insect has no sting, 
but that its motion is more rapid than that of the 
bee, and resembles that of the Gad-Fly in Eng- 
land; and that there is something particular in its 
sound or buzzing. It is a jarring noise, together 
with a humming, which induces Mr. Bruce to 
suppose that it proceeds, at least in part, from a 
vibration made with the three hairs at the snout. 
He observes farther, that the Chaldee version is 
content with calling this animal simply Zebub, 
which signifies the Fly in general, as we express 
it in English. The Arabs call it Zhiib in their 
translation. The Ethiopic translation calls it 
Tsaltsalya, which is the true name of this parti- 
cular fly in Geez, and was the same in Hebrew._
