  Family 
  CHRYSOMELIDiE. 
  

  

  These 
  are 
  the 
  "leaf-beetles," 
  having 
  the 
  same 
  tarsal 
  structure 
  as 
  in 
  

   the 
  "CerambycidasV; 
  but 
  with 
  antennae 
  rarely 
  as 
  long 
  as 
  the 
  body, 
  the 
  

   joints 
  comparatively 
  stouter 
  and 
  larger 
  toward 
  the 
  tip. 
  The 
  species 
  are 
  

   rarely 
  cylindrical 
  and 
  the 
  thorax 
  has 
  usually 
  either 
  a 
  lateral 
  margin 
  or 
  

   a 
  distinct 
  suture. 
  

  

  The 
  larvae 
  are 
  "slugs" 
  or 
  "grubs," 
  often 
  stout 
  and 
  chunky 
  like 
  those 
  

   of 
  the 
  potato 
  beetle 
  and 
  feeding 
  on 
  leaves, 
  or 
  they 
  may 
  be 
  long 
  and 
  slen- 
  

   der, 
  mining 
  in 
  root 
  or 
  leaf 
  tissue. 
  They 
  vary 
  much 
  in 
  habit, 
  although 
  

   always 
  feeders 
  on 
  vegetable 
  tissue, 
  and 
  many 
  of 
  them, 
  rank 
  among 
  the 
  

   first-class 
  pests. 
  As 
  against 
  those 
  that 
  feed 
  openly, 
  the 
  arsenites 
  are 
  

   usually 
  available; 
  but 
  ch.ere 
  are 
  some 
  that 
  must 
  be 
  dealt 
  with 
  in 
  other 
  

   ways, 
  depending 
  on 
  their 
  habits.
