  These 
  are 
  the 
  "back-swimmers," 
  so 
  named 
  because 
  the 
  upper 
  surface 
  is 
  

   keeled, 
  and 
  they 
  swim 
  back 
  down. 
  They 
  are 
  predatory, 
  and 
  "bite" 
  

   severely 
  if 
  carelessly 
  handled. 
  Mr. 
  Davis 
  lists 
  five 
  species 
  from 
  Staten 
  

   Island, 
  and 
  remarks 
  that 
  "they 
  are 
  most 
  common 
  in 
  fall 
  and 
  spring, 
  and 
  

   pass 
  the 
  winter 
  like 
  so 
  many 
  other 
  water 
  bugs 
  as 
  adults." 
  Mr. 
  Bueno 
  

   adds 
  that 
  "they 
  can 
  be 
  caught, 
  active, 
  under 
  the 
  ice 
  except 
  in 
  the 
  coldest 
  

   days 
  of 
  winter."
