  Mr. 
  Green 
  observed 
  that 
  in 
  Ceylon 
  certain 
  beetles 
  used 
  to 
  

   be 
  attracted 
  to 
  the 
  light 
  and 
  come 
  in 
  and 
  deposit 
  Nematode 
  

   worms 
  even 
  on 
  the 
  dinner-table.

  (1) 
  A 
  specimen 
  of 
  Anaitis 
  plagiata 
  showing 
  extreme 
  melan- 
  

   ism, 
  the 
  thorax, 
  abdomen, 
  basal 
  area 
  and 
  central 
  fascia 
  of 
  

   fore-wings 
  being 
  almost 
  black 
  and 
  the 
  rest 
  of 
  the 
  fore-wings 
  

   and 
  the 
  hind-wings 
  dark 
  grey.

  A 
  specimen 
  of 
  Acronycta 
  menyanthidis 
  with 
  black 
  

   marginal 
  area 
  to 
  fore-wings. 
  

  

  Both 
  were 
  from 
  Dumbartonshire, 
  1919. 
  Two 
  slightly 
  less 
  

   melanic 
  Anaitis

  Bred 
  Sesia

  — 
  Mr. 
  H. 
  M. 
  Edelsten 
  ex- 
  

   hibited 
  bred 
  specimens 
  of 
  Sesia 
  formicaeformis 
  from 
  the 
  Lea 
  

   Valley 
  ; 
  also 
  an 
  osier 
  stem 
  in 
  which 
  the 
  larva 
  had 
  fed, 
  and 
  

   photographs 
  to 
  show 
  the 
  emergence 
  hole 
  of 
  the 
  imago. 
  The 
  

   larvae 
  were 
  found 
  in 
  an 
  old 
  osier 
  bed 
  which 
  had 
  not 
  been 
  

   cut 
  for 
  several 
  years. 
  The 
  osiers 
  were 
  in 
  a 
  most 
  unhealthy 
  

   state, 
  and 
  there 
  were 
  numerous 
  dead 
  and 
  dying 
  stems. 
  The 
  

   stems 
  were 
  infested 
  with 
  Willow 
  Weevil 
  {Cryptorrynchus 
  

   lapathi) 
  and 
  Willow 
  Wood 
  Midge 
  {Cecidomyia 
  salidperda), 
  and 
  

   were 
  covered 
  with 
  rust 
  canker, 
  and 
  had 
  been 
  much 
  pecked 
  

   by 
  birds. 
  The 
  larvae 
  appear 
  to 
  feed 
  under 
  the 
  bark 
  in 
  their 
  

   early 
  stages 
  in 
  a 
  similar 
  way 
  to 
  those 
  of 
  Sesia 
  andrenaeformis, 
  

   afterwards 
  boring 
  up 
  the 
  dead 
  or 
  dying 
  stems 
  to 
  pupate. 
  

   They 
  make 
  no 
  cap 
  over 
  the 
  emergence 
  hole, 
  but 
  eat 
  away 
  

   the 
  inner 
  lining 
  xmtil 
  only 
  the 
  ciiticle 
  of 
  the 
  bark 
  remains. 
  

   The 
  emergence 
  hole 
  is 
  oval 
  in 
  shape 
  and 
  reminds 
  one 
  very 
  

   much 
  of 
  that 
  of 
  Nonagria 
  neurica. 
  The 
  pupa 
  is 
  head 
  up- 
  

   wards, 
  though 
  in 
  two 
  cases 
  he 
  had 
  found 
  them 
  head 
  down- 
  

   wards. 
  (These 
  were 
  ichneumoned, 
  and 
  had 
  probably 
  entered 
  

   an 
  old 
  boring.) 
  In 
  osiers 
  that 
  are 
  cut 
  regularly 
  the 
  larva 
  

   feeds 
  under 
  the 
  bark 
  and 
  pupates 
  there 
  like 
  Sesia 
  myopaeformis 
  . 
  

  

  Some 
  larvae 
  were 
  still 
  feeding 
  on 
  May 
  20, 
  and 
  others 
  were 
  

   quite 
  small, 
  so 
  it 
  is 
  evident 
  that 
  they 
  take 
  two 
  years, 
  if 
  not 
  

   three, 
  to 
  come 
  to 
  maturity. 
  The 
  pupae 
  were 
  enclosed 
  in
