  sometimes 
  penetrating 
  into 
  the 
  pith. 
  It 
  pupates 
  in 
  the 
  wood, 
  and 
  

   may 
  hibernate 
  there. 
  

  

  The 
  damage 
  to 
  the 
  tree 
  may 
  be 
  very 
  considerable 
  ; 
  the 
  early 
  work 
  

   of 
  the 
  larva 
  is 
  the 
  most 
  serious, 
  in 
  that 
  the 
  sap-flow 
  is 
  always 
  reduced, 
  

   and 
  may 
  even 
  be 
  stopped 
  ; 
  stems 
  and 
  branches 
  from 
  1-6 
  inches 
  in 
  

   diameter 
  may 
  be 
  destroyed 
  in 
  this 
  way. 
  The 
  only 
  remedy 
  is 
  to 
  

   remove 
  all 
  infested 
  stems 
  and 
  branches 
  during 
  the 
  winter 
  months, 
  

   and 
  burn 
  them. 
  In 
  this 
  way 
  the 
  weevils 
  are 
  destroyed 
  before 
  emerging.

  In 
  the 
  agricultural 
  section 
  of 
  the 
  report 
  it 
  is 
  stated 
  that 
  during 
  

   the 
  spring 
  of 
  1913 
  there 
  was 
  an 
  outbreak 
  in 
  Malta 
  of 
  the 
  fluted 
  scale- 
  

   insect, 
  Icerya 
  purchasi, 
  in 
  certain 
  localities, 
  but 
  that, 
  owing 
  to 
  the 
  

   drastic 
  measures 
  taken 
  and 
  the 
  timely 
  distribution 
  of 
  the 
  ladybird, 
  

   Novius 
  cardinalis, 
  the 
  spread 
  of 
  the 
  pest 
  was 
  checked.

  A 
  description 
  is 
  given 
  of 
  a 
  new 
  species 
  of 
  Tineidae, 
  referred 
  to 
  by 
  

   Mr. 
  A. 
  G. 
  Ruggles 
  as 
  having 
  an 
  important 
  bearing 
  upon 
  the 
  spread 
  of 
  

   the 
  chestnut 
  bark 
  disease 
  [see 
  this 
  Review 
  Ser. 
  A, 
  ii, 
  pp. 
  29]. 
  The 
  new 
  

   species 
  which 
  has 
  been 
  called 
  Ectoedemia 
  phleophaga, 
  Busck, 
  is 
  closely 
  

   allied 
  to 
  the 
  other 
  species 
  of 
  this 
  genus 
  which 
  feeds 
  on 
  chestnut, 
  

   the 
  gall-making 
  E. 
  castaneae, 
  Busck. 
  The 
  larva 
  was 
  found 
  in 
  

   the 
  lower 
  layer 
  of 
  the 
  bark 
  of 
  a 
  chestnut, 
  encroaching 
  upon 
  

   the 
  cambium. 
  The 
  mine 
  is 
  slender 
  and 
  serpentine, 
  a 
  few 
  milli- 
  

   metres 
  broad 
  and 
  several 
  centimetres 
  long 
  ; 
  in 
  April 
  and 
  May 
  

   the 
  fully 
  grown 
  larva 
  leaves 
  the 
  mine 
  and 
  falls 
  to 
  the 
  ground, 
  where 
  

   it 
  makes 
  a 
  cocoon, 
  often 
  boring 
  down 
  a 
  few 
  inches 
  into 
  the 
  loose 
  surface 
  

   soil. 
  From 
  the 
  specimens 
  reared, 
  imagos 
  emerged 
  during 
  September. 
  

   The 
  specimen 
  described 
  was 
  taken 
  at 
  Falls 
  Church, 
  Virginia.
