  swarm 
  of 
  hoppers 
  had 
  been 
  reported 
  in 
  the 
  Tampin 
  districts. 
  In 
  the 
  

   Coast 
  district 
  numerous 
  small 
  swarms 
  occurred, 
  and 
  the 
  Special 
  

   Assistant 
  with 
  one 
  gang 
  destroyed 
  42 
  swarms. 
  The 
  deficiency 
  in 
  the 
  

   amount 
  of 
  apparatus 
  has 
  constituted 
  a 
  severe 
  handicap 
  on 
  the 
  work. 
  

   The 
  damage 
  caused 
  by 
  the 
  locusts 
  has 
  not 
  been 
  very 
  serious.

  The 
  material 
  used 
  for 
  this 
  description 
  of 
  the 
  gunworm 
  {Sciopteron 
  

   regale, 
  Butl.), 
  a 
  Sesiid 
  moth, 
  was 
  taken 
  from 
  some 
  confiscated 
  vine- 
  

   cuttings 
  brought 
  from 
  Yokahama 
  to 
  San 
  Francisco 
  by 
  a 
  passenger. 
  

   Swellings 
  on 
  the 
  twigs 
  indicated 
  some 
  abnormality, 
  and 
  were 
  found 
  to 
  

   contain 
  the 
  larvae 
  of 
  a 
  Sesiid 
  borer. 
  These 
  larvae 
  bore 
  into 
  the 
  canes 
  

   of 
  the 
  grape-vines 
  and 
  are 
  very 
  destructive 
  in 
  Japan.

  The 
  author 
  received 
  twigs 
  of 
  apricot 
  trees 
  severely 
  injured 
  by 
  a 
  

   Bostrychid 
  beetle, 
  Amphicerus 
  punctipennis, 
  Lee. 
  The 
  burrows, 
  which 
  

   may 
  occur 
  anywhere 
  on 
  the 
  twigs, 
  vary 
  from 
  one 
  to 
  three 
  inches 
  in 
  

   length 
  and 
  are 
  about 
  one-eighth 
  of 
  an 
  inch 
  m 
  diameter. 
  The 
  beetles 
  

   bore 
  into 
  the 
  twigs 
  for 
  food 
  and 
  protection, 
  not 
  to 
  deposit 
  eggs, 
  and 
  the 
  

   burrows 
  cause 
  the 
  smaller 
  twigs 
  to 
  break. 
  This 
  species 
  seems 
  to 
  prefer 
  

   dead 
  or 
  dying 
  wood.

   reported 
  by 
  Dr. 
  Van 
  Dyke 
  as 
  the 
  normal 
  food-plant, 
  and 
  other 
  known 
  

   hosts 
  are 
  pear, 
  dead 
  fig-tree 
  branches, 
  dry 
  canes 
  of 
  the 
  grape-vine, 
  

   apricot 
  and 
  dry 
  orange 
  wood. 
  It 
  has 
  a 
  wide 
  distribution 
  in 
  South 
  

   West 
  California, 
  Dr. 
  Van 
  Dyke 
  specially 
  mentioning 
  Los 
  Angeles 
  and 
  

   Imperial 
  Counties. 
  Control 
  measures 
  suggested 
  are, 
  the 
  destruction 
  

   of 
  breeding 
  places 
  if 
  possible, 
  the 
  elimination 
  of 
  unhealthy 
  trees 
  and 
  all 
  

   dead 
  wood, 
  and 
  the 
  maintenance 
  of 
  trees 
  in 
  good 
  growing 
  vigour.
