  columba 
  Linn. 
  The 
  larva 
  bores 
  into 
  the 
  trunlts 
  of 
  a 
  variety 
  of 
  shade 
  

   and 
  orchard 
  trees 
  throughout 
  the 
  State, 
  IX, 
  sometimes 
  causing 
  con- 
  

   siderable 
  injury. 
  It 
  is 
  popularly 
  known 
  as 
  the 
  "Pigeon 
  Tremex," 
  and 
  

   no 
  practical 
  method 
  of 
  dealing 
  with 
  it 
  is 
  known. 
  It 
  is 
  kept 
  down 
  by 
  

   parasites, 
  and 
  as 
  it 
  usually 
  attacks 
  only 
  weak 
  or 
  dying 
  trees 
  we 
  

   can 
  lessen 
  the 
  danger 
  by 
  keeping 
  trees 
  in 
  good 
  condition. 
  

   "T. 
  sericeus" 
  Say, 
  is 
  now 
  regarded 
  as 
  a 
  variety.

  These 
  are 
  loose-jointed, 
  slender 
  saw-flies 
  of 
  rather 
  soft 
  texture, 
  with 
  

   long, 
  slender, 
  peculiarly 
  jointed 
  antennae. 
  The 
  ovipositor 
  is 
  a 
  little 
  pro- 
  

   duced 
  and 
  the 
  larvse 
  live 
  in 
  stems 
  of 
  plants 
  and 
  the 
  tender 
  growth 
  of 
  

   trees 
  and 
  shrubs.

  Is 
  the 
  currant 
  stem 
  

   girdler, 
  the 
  larva 
  tunnelling 
  the 
  pith 
  of 
  the 
  currant. 
  Its 
  work 
  is 
  not 
  

   rarely 
  seen, 
  but 
  the 
  insects 
  are 
  not 
  common.
