GENUS 8.—ASILUS. 
This is called by fome authors the wasp fly, and 
not improperly, as, like the wafp, it ftings feverely 
whatever offends it, though with a different inflru- 
ment, namely, its probofcis (for which reafon it 
ought not to be taken without precaution). They 
fling with this inffrument different animals, and draw 
out their blood, which they fuck through their 
trunk. They are very troublefome to cattle in low 
meadows, where they are frequently met with.— 
The larvae and chryfalids are not known. This in¬ 
feet was caught in Kyde-park. Asiius Crabrcnifor -
