  The 
  small 
  beetle, 
  Colaspidema 
  atra, 
  Latr., 
  called 
  in 
  France 
  " 
  N^gril," 
  

   on 
  account 
  of 
  its 
  black 
  colour, 
  causes 
  serious 
  damage 
  every 
  year 
  to 
  

   lucerne 
  crops 
  in 
  the 
  neighbourhood 
  of 
  Toulouse. 
  It 
  is 
  common 
  in 
  

   other 
  parts 
  in 
  the 
  south 
  of 
  Europe. 
  In 
  May 
  and 
  June 
  the 
  hibernating 
  

   adults 
  appear, 
  and 
  soon 
  after 
  the 
  larvae 
  are 
  found 
  in 
  the 
  fields 
  of 
  

   lucerne. 
  The 
  present 
  paper 
  deals 
  with 
  experiments 
  made 
  to 
  deter- 
  

   mine 
  the 
  number 
  of 
  eggs 
  laid 
  by 
  the 
  female 
  during 
  her 
  lifetime, 
  and 
  

   the 
  results 
  indicate 
  that 
  a 
  single 
  female 
  may 
  lay 
  almost 
  1,000 
  eggs 
  

   from 
  April 
  to 
  June. 
  This 
  degree 
  of 
  fecundity 
  was 
  maintained 
  both 
  

   when 
  fertihsation 
  occurred 
  only 
  once 
  or 
  was 
  repeated 
  several 
  times. 
  

   The 
  degree 
  of 
  fertility 
  in 
  different 
  individuals 
  was 
  very 
  variable.

  The 
  observations 
  recorded 
  in 
  this 
  paper, 
  upon 
  the 
  relationship 
  

   between 
  certain 
  insects, 
  were 
  made 
  at 
  Oni, 
  in 
  Southern 
  Nigeria, 
  in 
  a 
  

   bush 
  camp, 
  situated 
  70 
  miles 
  E. 
  of 
  the 
  town 
  of 
  Lagos 
  and 
  about 
  10 
  

   miles 
  from 
  the 
  sea. 
  Although 
  most 
  of 
  the 
  work 
  done 
  is 
  of 
  purely 
  

   scientific 
  interest, 
  certain 
  points 
  are 
  noted 
  which 
  are 
  of 
  economic 
  

   importance.

  were

  and

  habit 
  is 
  recorded 
  

   of

  The 
  author 
  received, 
  in 
  October 
  1913, 
  specimens 
  of 
  bark 
  from 
  a 
  

   common 
  beech 
  tree 
  covered 
  with 
  an 
  insect 
  which 
  was 
  stated 
  to 
  be 
  

   noticeable 
  all 
  through 
  the 
  woods 
  in 
  the 
  vicinity 
  of 
  Halifax, 
  N.S. 
  Dr. 
  

   Howard 
  identified 
  it 
  as 
  the 
  European 
  felt 
  scale 
  {Cryptococcus 
  fagi, 
  

   Baerens). 
  In 
  Britain 
  this 
  insect 
  confines 
  its 
  attacks 
  to 
  the 
  beech 
  

   {Fagus 
  sylvatica), 
  the 
  copper 
  beech 
  being 
  all 
  but 
  immune. 
  The 
  

   specimens 
  from 
  Nova 
  Scotia 
  are 
  doubtless 
  from 
  the 
  American 
  beech 
  

   (F. 
  grandifolia,'Eih.Th..), 
  an 
  entirely 
  new 
  food-plant, 
  and 
  prompt 
  measures 
  

   should 
  be 
  taken 
  for 
  its 
  extermination, 
  since 
  it 
  would 
  appear 
  that 
  

   the 
  insect 
  is 
  taking 
  well 
  to 
  its 
  new 
  conditions. 
  This 
  seems 
  to 
  be 
  the 
  

   first 
  record 
  of 
  the 
  occurrence 
  of 
  this 
  Coccid 
  in 
  North 
  America.
