  green, 
  towards 
  the 
  extremity 
  or 
  just 
  above 
  the 
  scar 
  left 
  by 
  the 
  perianth. 
  

   After 
  about 
  8 
  or 
  12 
  days 
  a 
  white 
  larvae 
  emerges 
  and 
  penetrates 
  into 
  

   the 
  berry. 
  The 
  larva 
  completes 
  its 
  growth 
  in 
  three 
  or 
  four 
  weeks 
  

   and 
  pupates 
  in 
  the 
  seed, 
  the 
  adult 
  insect 
  appearing 
  15 
  to 
  19 
  days 
  later. 
  

   The 
  presence 
  of 
  the 
  beetle 
  is 
  revealed 
  by 
  two 
  or 
  three 
  small 
  holes, 
  

   at 
  the 
  summit 
  of 
  the 
  fruit. 
  The 
  pulp 
  is 
  simply 
  crossed 
  by 
  the 
  insect, 
  

   and 
  only 
  the 
  seeds 
  are 
  devoured 
  by 
  the 
  larvae, 
  so 
  that 
  at 
  a 
  certain 
  

   distance 
  the 
  berries 
  appear 
  in 
  good 
  condition, 
  containing 
  only 
  damaged 
  

   seeds. 
  According 
  to 
  Gowdey 
  the 
  best 
  means 
  of 
  controlling 
  S. 
  coffeae 
  

   is 
  by 
  gathering 
  and 
  destroying 
  the 
  attacked 
  berries. 
  This 
  species 
  

   proves 
  to 
  be 
  "widespread 
  ; 
  the 
  specimens 
  originally 
  described 
  came 
  

   from 
  Uganda, 
  but 
  Hagedorn 
  has 
  since 
  received 
  examples 
  from 
  Angola, 
  

   the 
  Congo 
  and 
  Java. 
  According 
  to 
  Morstatt 
  it 
  did 
  not 
  exist 
  in 
  German 
  

   East 
  Africa 
  in 
  1912. 
  In 
  Uganda 
  Coffea 
  arahica 
  appeared 
  to 
  suffer 
  

   less 
  from 
  the 
  attacks 
  of 
  this 
  insect 
  than 
  indigenous 
  cofiee 
  trees.

  In 
  this 
  article 
  reference 
  is 
  made 
  to 
  a 
  paper 
  by 
  Wenk 
  in 
  the 
  Geisen- 
  

   Jieimer 
  Mitteilungen 
  iiber 
  Ohst 
  und 
  Gartenbau, 
  and 
  the 
  following 
  remarks 
  

   are 
  all 
  taken 
  from 
  it. 
  The 
  incorrect 
  use 
  of 
  carbohneum 
  has 
  led 
  to 
  its 
  

   being 
  discarded 
  entirely 
  by 
  many 
  experts. 
  If 
  properly 
  applied 
  it 
  is 
  a 
  

   valuable 
  agent. 
  Scale-insects 
  are 
  easily 
  destroyed 
  if 
  the 
  trunk 
  and 
  

   branches 
  of 
  the 
  tree 
  are 
  painted 
  with, 
  a 
  40 
  per 
  cent, 
  solution. 
  This 
  

   strength 
  kills 
  the 
  scales, 
  which 
  is 
  not 
  always 
  the 
  case 
  with 
  weaker 
  

   solutions. 
  Spraying 
  must 
  not 
  be 
  done 
  with 
  solutions 
  above 
  15 
  per 
  

   cent, 
  in 
  strength, 
  as 
  the 
  young 
  shoots 
  and 
  buds 
  will 
  suffer. 
  It 
  is 
  of 
  

   the 
  greatest 
  importance 
  that 
  carbolineum 
  be 
  used 
  only 
  when 
  the 
  

   sap-flow 
  is 
  in 
  abeyance. 
  From 
  the 
  beginning 
  of 
  February 
  to 
  the 
  

   middle 
  of 
  March 
  is 
  the 
  period 
  advised 
  by 
  Wenk, 
  as 
  then 
  the 
  insects 
  

   are 
  leaving 
  their 
  winter 
  refuges 
  and, 
  on 
  the 
  other 
  hand, 
  shoots 
  and 
  

   buds 
  have 
  not 
  yet 
  appeared. 
  When 
  they 
  do 
  so 
  the 
  use 
  of 
  carbolineum 
  

   must 
  be 
  immediately 
  discontinued. 
  The 
  product 
  itself 
  must 
  be 
  

   completely 
  soluble 
  in 
  water 
  and 
  the 
  actual 
  percentage 
  of 
  carbohnemn 
  

   contained 
  m 
  it 
  is 
  of 
  great 
  importance, 
  and 
  should 
  be 
  guaranteed, 
  as 
  

   some 
  inferior 
  makes 
  may 
  contain 
  over 
  90 
  per 
  cent, 
  of 
  water 
  and 
  would 
  

   prove 
  very 
  expensive 
  in 
  use.

  Potatoes 
  sent 
  to 
  the 
  United 
  States 
  from 
  South 
  America 
  were 
  found 
  

   on 
  several 
  occasions 
  to 
  contain 
  weevils, 
  in 
  all 
  stages 
  of 
  development. 
  

   Three 
  species 
  of 
  weevil 
  are 
  involved, 
  one 
  of 
  which, 
  Rhigopsidius 
  

   hicumanus, 
  Hiller, 
  has 
  been 
  already 
  reported 
  as 
  found 
  in 
  potatoes 
  

   shipped 
  from 
  Chile, 
  Peru 
  and 
  Bolivia. 
  [See 
  this 
  Review

  The 
  other 
  two 
  species, 
  described 
  in 
  the 
  present 
  paper, 
  are 
  

   new 
  and 
  represent 
  new 
  genera. 
  One 
  of 
  these, 
  Premnotrypes 
  solani, 
  

   was 
  found 
  in 
  the 
  adult 
  stage, 
  just 
  mider 
  the 
  skin 
  of 
  the 
  potato, 
  in 
  a 
  

   small 
  cell 
  in 
  which 
  the 
  larva 
  had 
  evidentlv 
  fed 
  ;
