  responsible 
  for 
  the 
  gradual 
  destruction 
  of 
  the 
  sinuate, 
  pear 
  

   borer,

  needs 
  two 
  years 
  to 
  attain 
  full 
  growth, 
  and 
  is 
  long 
  in 
  

   the 
  helpless

  The

  Family

  A 
  very 
  interesting 
  group 
  of 
  beetles, 
  varying 
  so 
  greatly 
  in 
  form 
  that 
  no 
  

   superficial 
  description 
  is 
  sufficiently 
  comprehensive 
  to 
  include 
  all. 
  They 
  

   are 
  hard 
  in 
  texture, 
  and 
  the 
  elytra, 
  which 
  may 
  be 
  smooth, 
  striate, 
  shining, 
  

   hairy 
  or 
  scaly, 
  are 
  not 
  abbreviated, 
  but 
  cover 
  the 
  abdomen. 
  The 
  head 
  

   is 
  usually 
  bent 
  under, 
  the 
  antennae 
  are 
  slender, 
  sometimes 
  evenly 
  serrate, 
  

   but 
  more 
  usually 
  with 
  a 
  prominent 
  serrate, 
  lamellate 
  or 
  pectinated 
  club. 
  

   They 
  live 
  on 
  dry 
  animal 
  and 
  vegetable 
  products, 
  and 
  some 
  of 
  them 
  bore 
  

   into 
  the 
  furniture 
  and 
  woodwork 
  of 
  houses, 
  to 
  their 
  material 
  injury. 
  All 
  

   sorts 
  of 
  things 
  from 
  Belladonna 
  roots 
  to 
  cigars 
  and 
  gunwads 
  are 
  attacked 
  

   and 
  serve 
  as 
  food. 
  

  

  The 
  larvae 
  occur 
  with 
  the 
  adults, 
  and 
  are 
  soft, 
  white, 
  grub-like 
  creatures 
  

   resembling 
  miniature 
  white-grubs, 
  but 
  covered 
  with 
  short 
  stiff 
  hair 
  or 
  

   bristles.
