   The 
  species 
  of 
  this 
  genus 
  are 
  all 
  nut-weevils, 
  and 
  those 
  that 
  feed 
  in 
  

   hickory 
  and 
  chestnut 
  are 
  often 
  seriously 
  injurious. 
  The 
  chestnut 
  weevils 
  

   in 
  New 
  Jersey 
  are 
  especially 
  troublesome 
  where 
  the 
  European 
  and 
  Jap- 
  

   anese 
  varieties 
  are 
  grown. 
  There 
  is 
  no 
  insecticide 
  that 
  is 
  available 
  to 
  

   reach 
  the 
  insect 
  in 
  any 
  stage, 
  and 
  the 
  only 
  methods 
  of 
  control 
  are 
  to 
  

   collect 
  the 
  nuts 
  as 
  soon 
  as 
  they 
  fall 
  and 
  market 
  them, 
  or 
  to 
  store 
  them 
  

   in 
  tight 
  barrels, 
  from 
  Avhich 
  the 
  larvje 
  cannot 
  escape 
  when 
  they 
  emerge 
  

   from 
  the 
  nuts. 
  

  

  Family 
  BRENTHID^. 
  

  

  Contains 
  only 
  a 
  single 
  very 
  curious 
  species, 
  in 
  which 
  the 
  males 
  have 
  

   prominent 
  mandibles 
  at 
  the 
  ends 
  of 
  the 
  short 
  robust 
  snout, 
  and 
  the 
  

   females 
  have 
  long, 
  cylindrical 
  beaks, 
  by 
  means 
  of 
  which 
  they 
  bore 
  into 
  

   the 
  wood 
  to 
  lay 
  their 
  eggs. 
  When 
  these 
  beaks 
  become 
  wedged, 
  as 
  they 
  

   sometimes 
  do, 
  the 
  males 
  use 
  their 
  forceps-like 
  jaws 
  to 
  pull 
  them 
  out.
