  INSECTS 
  INJURIOUS 
  TO 
  MISCELLANEOUS 
  PLANTS. 
  

  

  Lepidoptera. 
  

  

  Thalassoides 
  digressa, 
  Walk. 
  The 
  larvae 
  occasionally 
  feed 
  on 
  the 
  leaves 
  of 
  the 
  

   castor 
  plant. 
  

  

  Duomitus 
  capensis, 
  Wlk. 
  The 
  larvae 
  have 
  been 
  found 
  tunnelling 
  in 
  the 
  main 
  

   stem 
  of 
  the 
  castor 
  plant. 
  

  

  Brithys 
  pancratii, 
  Cyr. 
  The 
  caterpillars 
  are 
  voracious 
  feeders 
  on 
  all 
  species 
  of 
  

   lilies 
  ; 
  when 
  young 
  they 
  are 
  gregarious 
  and 
  feed 
  under 
  the 
  epidermis 
  of 
  the 
  leaf, 
  

   later 
  they 
  separate 
  and 
  devour 
  the 
  whole 
  plant. 
  Pupation 
  takes 
  place 
  in 
  the 
  soil 
  

   or 
  at 
  the 
  base 
  of 
  the 
  leaves, 
  the 
  pupal 
  stage 
  averaging 
  from 
  8 
  to 
  10 
  days. 
  

  

  Euchromia 
  formosa, 
  Guer. 
  The 
  larva 
  is 
  clothed 
  with 
  tufts 
  of 
  hairs, 
  dull-coloured 
  

   and 
  inconspicuous, 
  and 
  forms 
  a 
  cocoon 
  of 
  silk 
  and 
  hairs 
  on 
  the 
  branches 
  of 
  the 
  

   food-plant. 
  It 
  is 
  common 
  on 
  all 
  species 
  of 
  creepers 
  belonging 
  to 
  the 
  genus 
  Ipomoea. 
  

  

  Glyphodes 
  sericea, 
  Drury. 
  The 
  larvae 
  are 
  common 
  on 
  gardenias. 
  Adult 
  larvae 
  

   are 
  of 
  a 
  transparent 
  green 
  colour 
  with 
  four 
  black 
  spots 
  on 
  the 
  dorsum. 
  They 
  are 
  

   leaf-rollers 
  and 
  live 
  and 
  pupate 
  in 
  twisted 
  leaves, 
  their 
  pupal 
  stage 
  averaging 
  9 
  

   days. 
  

  

  Coleoptera. 
  

  

  Entyposis 
  impressa, 
  Kolbe. 
  Larvae 
  of 
  this 
  weevil 
  have 
  been 
  recorded 
  as 
  feeding 
  

   on 
  the 
  roots 
  of 
  castor 
  plants 
  and 
  caladiums. 
  

  

  Brachycerus 
  atrox, 
  Gerst. 
  Great 
  numbers 
  of 
  adult 
  weevils 
  have 
  been 
  taken 
  in 
  

   the 
  soil 
  around 
  the 
  tubers 
  of 
  lilies 
  (Amaryllis 
  sp.). 
  During 
  the 
  day 
  they 
  hide 
  in 
  

   burrows 
  near 
  their 
  food-plant 
  and 
  come 
  out 
  to 
  feed 
  on 
  the 
  leaves 
  at 
  night. 
  Larvae 
  

   feed 
  on 
  the 
  tubers, 
  eating 
  into 
  the 
  centre. 
  

  

  Mausoleopis 
  amabilis, 
  Schaum. 
  Adults 
  of 
  this 
  Cetoniid 
  are 
  common 
  in 
  the 
  

   blossoms 
  of 
  various 
  ornamental 
  plants, 
  especially 
  roses. 
  

  

  Rhynchota. 
  

  

  Aspidiotus 
  (Chrysomphalus) 
  aonidum,, 
  L. 
  A 
  common 
  scale-insect 
  on 
  rose 
  stalks. 
  

   Pseudococcus 
  virgatus, 
  Ckll. 
  Has 
  been 
  recorded 
  from 
  various 
  ornamental 
  

   creepers, 
  etc. 
  

  

  Orthoptera. 
  

  

  Chrotogonus 
  hemipterus, 
  Schaum. 
  A 
  very 
  troublesome 
  grasshopper 
  ; 
  one 
  

   experimental 
  field 
  of 
  castor 
  was 
  ruined 
  by 
  its 
  depredations. 
  

  

  INSECTS 
  INJURIOUS 
  TO 
  STORED 
  PRODUCTS. 
  

  

  In 
  the 
  tropics, 
  where 
  food 
  is 
  abundant 
  throughout 
  the 
  year, 
  insects 
  attacking 
  

   stored 
  grain 
  are 
  more 
  in 
  evidence 
  than 
  in 
  Europe. 
  Owing 
  to 
  the 
  custom 
  of 
  storing 
  

   grain 
  in 
  loose 
  receptacles 
  and 
  exposing 
  it 
  in 
  open 
  bins 
  for 
  sale 
  nearly 
  every 
  sample 
  

   showed 
  evidence 
  of 
  insect 
  attack.
