  Family 
  GYRINID^. 
  

  

  These 
  are 
  the 
  "Whirligig 
  beetles," 
  so 
  named 
  because 
  of 
  their 
  habit 
  of 
  

   swimming 
  about 
  in 
  groups 
  or 
  swarms 
  on 
  the 
  surface 
  of 
  ponds 
  or 
  quiet 
  

   streams 
  and 
  ditches, 
  the 
  individuals 
  often 
  whirling 
  round 
  and 
  round 
  

   without 
  apparent 
  aim. 
  They 
  are 
  black 
  or 
  a 
  little 
  bronzed, 
  convex 
  above, 
  

   flattened 
  below, 
  with 
  short, 
  paddle-like 
  swimming 
  legs, 
  the 
  anterior 
  pair 
  

   long 
  and 
  arm-like. 
  When 
  handled 
  many 
  of 
  them 
  emit 
  a 
  milky 
  white 
  fluid 
  

   which 
  has 
  a 
  fruity 
  odor, 
  that 
  gives 
  them 
  the 
  local 
  name 
  "Apple-bugs." 
  

   They 
  are 
  predatory 
  in 
  the 
  larval 
  as 
  well 
  as 
  the 
  adult 
  stage, 
  and 
  among 
  

   others 
  feed 
  on 
  the 
  larvse 
  of 
  "Anopheles," 
  which 
  are 
  never 
  found 
  where 
  

   these 
  beetles 
  occur 
  in 
  numbers.
