tyrannical ; they deftroy, like wolves among flieep, 
twenty times as many as their hunger requires. If one 
of them is placed in a bafon of water with thirty or forty 
worms of the libellula, each as large as itfelf, it will de- 
Itroy them all in a very Ihort fpace, getting on their 
backs, and piercing them through the body with its roll- 
rum *. 
Thefe animals, though they live upon the water by 
day, are capable of taking long flights from one pool to 
another in quell of food : This they are probably often 
obliged to attempt, from the fiercenefs of their manners, 
by which the infedts in their vicinity muft be focn de- 
ftroyed. Though fo formidable to other creatures, they , 
are neverthclefs haunted by a little loufe, which probp.bly 
repays the injuries which the water fcorpion fo frequent- 
ly commits upon others. 
The cinereous fcorpion is the moil common in feel of 
this tribe: The head is fmail, and as it were funk in a 
Hope of the thorax ; the elytra are broad, crofs each 
other, and cover almoft the whole abdomen : In the fe- 
males, the extremity is furnifhed with two appendices, 
equal to three fourths of its length.
