  British 
  Guiana, 
  has 
  shown 
  itself 
  to 
  be 
  pecuharly 
  free 
  from 
  insect 
  

   attack, 
  but 
  the 
  following 
  insects, 
  principally 
  Coccidae, 
  have 
  been 
  

   observed 
  to 
  attack 
  it 
  in 
  the 
  Colony 
  : 
  — 
  Erinnyis 
  ello 
  ; 
  Tropidacris 
  

   cristata, 
  and 
  an 
  undetermined 
  Locustid 
  ;

  The 
  caterpillars 
  of 
  Brassolis 
  sopJiorae 
  still 
  continue 
  to 
  damage 
  

   coconut 
  palms 
  in 
  all 
  parts 
  of 
  the 
  Colony, 
  as 
  trouble 
  is 
  seldom 
  taken 
  to 
  

   apply 
  the 
  comparatively 
  easy 
  control 
  measures 
  recommended. 
  Other 
  

   pests 
  are 
  a 
  large 
  black 
  Dynastid 
  beetle 
  {Strategus 
  aloeus, 
  F.); 
  Aspidiotus 
  

   destructor, 
  which 
  is 
  easily 
  controlled 
  by 
  kerosene 
  emulsion 
  and 
  is 
  preyed 
  

   upon 
  by 
  Cryptognatha 
  nodiceps, 
  MshlL, 
  and 
  Azya 
  trinitalis, 
  Mshll. 
  ; 
  and 
  

   the 
  palm 
  weevil, 
  Rhynchophorus 
  palmarum, 
  L. 
  The 
  following 
  list 
  is 
  

   given 
  of 
  the 
  insects 
  injurious 
  to 
  coconut 
  palms 
  in 
  British 
  Guiana 
  : 
  — 
  

   Castnia

  Citrus 
  plants 
  cultivated 
  in 
  suitable 
  soils 
  have 
  been 
  singularly 
  free 
  

   from 
  the 
  attack 
  of 
  insects, 
  particularly 
  of 
  Coccidae. 
  This 
  is 
  due 
  to 
  

   the 
  heavy 
  rainfall 
  and 
  the 
  presence 
  of 
  parasitic 
  fungi 
  such 
  as 
  Cephalo- 
  

   sporium 
  lecanii 
  and 
  Sphaerostilbe 
  coccophila. 
  Where 
  the 
  plants 
  are 
  

   poorly 
  cultivated 
  in 
  the 
  heavy 
  clay 
  soils 
  of 
  the 
  coastlands, 
  they 
  are 
  

   attacked 
  by 
  many 
  scale-insects, 
  as 
  many 
  as 
  six 
  distinct 
  species 
  often 
  

   occurring 
  on 
  a 
  single 
  tree. 
  An 
  accompanying 
  black 
  bhght 
  is 
  character- 
  

   istic 
  of 
  scale 
  attack. 
  A 
  list 
  of 
  these 
  Coccids 
  is 
  given 
  [see

  Review, 
  

   Ser. 
  A,

  On

  During 
  the 
  period 
  under 
  review 
  no 
  severe 
  outbreak 
  of 
  insect 
  pests 
  

   occurred, 
  but 
  several 
  new 
  ones 
  have 
  been 
  discovered 
  and 
  the 
  old 
  ones 
  

   were 
  more 
  or 
  less 
  abundant. 
  

  

  Lamellicorn 
  beetle 
  larvae 
  did 
  more 
  than 
  the 
  usual 
  amount 
  of 
  damage, 
  

   especially 
  on 
  badly 
  cultivated 
  land. 
  As 
  the 
  roots 
  of 
  bush 
  and 
  grasses 
  

   form 
  the 
  natural 
  food 
  of 
  these 
  pests, 
  clean 
  cultivation 
  and 
  the 
  removal 
  

   of 
  wild 
  grass, 
  &c., 
  near 
  the 
  crops 
  is 
  an 
  obvious 
  remedy 
  ; 
  fallow 
  land 
  

   should 
  also 
  be 
  frequently 
  cultivated 
  in 
  order 
  to 
  keep 
  down 
  wild 
  food 
  

   plants 
  and 
  thus 
  starve 
  out 
  the 
  grubs. 
  The 
  adult 
  beetles 
  fly 
  by 
  night 
  

   and 
  destroy 
  the 
  foliage 
  of 
  trees 
  and 
  bushes, 
  especially 
  of 
  vines 
  and 
  

   fruit 
  trees. 
  In 
  the 
  daytime 
  they 
  may 
  be 
  found 
  round 
  the 
  stems 
  of 
  

   the 
  plants 
  1 
  to 
  3 
  inches 
  below 
  the 
  surface. 
  They 
  may 
  be 
  readily 
  dug 
  

   up 
  and 
  destroyed, 
  and 
  a 
  boy, 
  who 
  had 
  been 
  showTi 
  how 
  to 
  collect, 
  

   brought 
  in 
  500 
  in 
  one 
  day. 
  Schizoneura 
  lanigera 
  has 
  been 
  found 
  in 
  

   new 
  locaHties, 
  possibly 
  imported 
  with 
  the 
  soil 
  attached 
  to 
  nursery
