  ish-yellow, 
  with 
  no 
  other 
  markings 
  ; 
  the 
  legs 
  are 
  a 
  little 
  paler 
  toward 
  the 
  articulations. 
  

   The'antennsB 
  are 
  eight-jointed, 
  slightly 
  longer 
  than 
  the 
  head;

  the 
  three 
  succeeding 
  joints 
  equal, 
  regularly 
  ovate, 
  the 
  sixth 
  a 
  little 
  longer 
  than 
  

   the 
  fifth 
  ; 
  seventh 
  and 
  eighth 
  minute, 
  seventh 
  a 
  little 
  shorter 
  than 
  eighth, 
  each 
  joint 
  

   bearing 
  four 
  large 
  bristles. 
  This 
  species 
  differs 
  from 
  the 
  European 
  L. 
  cerealium 
  in 
  hav- 
  

   ing 
  but 
  eight 
  joints, 
  the 
  seventh 
  and 
  eighth 
  being 
  minute, 
  and 
  with 
  no 
  intermediate 
  

   short 
  one, 
  as 
  described 
  in 
  the 
  European 
  insect. 
  

  

  "The 
  prothorax 
  is 
  square, 
  the 
  scutellum 
  short, 
  crescent-shaped, 
  and 
  the 
  abdomen 
  is 
  

   long 
  and 
  narrow, 
  smooth 
  and 
  shining, 
  ten-jointed. 
  Length, 
  four 
  one-hundredths 
  of 
  au 
  

   inch, 
  or 
  less 
  than 
  half 
  a 
  line. 
  

  

  "The 
  larva 
  (Plate 
  LXVII, 
  Fig. 
  4 
  &) 
  is 
  entirely 
  greenish-yellow, 
  the 
  head 
  and 
  prothorax 
  

   of 
  the 
  same 
  color 
  as 
  the 
  rest 
  of 
  the 
  body 
  ; 
  the 
  eyes 
  are 
  reddish 
  ; 
  the 
  feet 
  and 
  antenuse 
  are 
  

   whitish, 
  not 
  annulated, 
  as 
  in 
  L. 
  cerealium; 
  the 
  feet 
  (tarsi) 
  consist 
  of 
  but 
  a 
  single 
  

   joint 
  ending 
  in 
  a 
  point. 
  

  

  "The 
  male 
  (Plate 
  LXVII, 
  Fig. 
  4 
  a) 
  differs 
  from 
  the 
  larva 
  in 
  having 
  two-jointed 
  feet 
  

   (tarsi) 
  and 
  seven-jointed 
  antenn0B,those 
  of 
  the 
  larva 
  being 
  four-jointed. 
  The 
  second 
  joint 
  

   is 
  exactly 
  barrel-shaped, 
  with 
  two 
  ridges 
  or 
  lines 
  surrounding 
  it, 
  third 
  and 
  fourth 
  joints 
  

   long, 
  ovate, 
  the 
  third 
  being 
  a 
  little 
  larger 
  than 
  the 
  fourth, 
  and 
  with 
  about 
  twelve 
  trans- 
  

   verse 
  lines, 
  there 
  being 
  about 
  eight 
  on 
  the 
  fourth 
  joint, 
  from 
  the 
  end 
  of 
  which 
  projects 
  

   a 
  remarkable 
  tubercle, 
  as 
  seen 
  in 
  the 
  figure. 
  The 
  fifth 
  joint 
  is 
  square 
  at 
  the 
  end, 
  with 
  

   about 
  eleven 
  transverse 
  lines, 
  and 
  three 
  or 
  four 
  stout 
  hairs 
  externally; 
  sixth 
  joint 
  

   minute 
  and 
  spherical, 
  while 
  the 
  seventh 
  is 
  three 
  times 
  as 
  long 
  as 
  the 
  sixth, 
  and 
  is 
  finely 
  

   striated, 
  and 
  with 
  four 
  unequal 
  stout 
  hairs. 
  It 
  is 
  just 
  twice 
  the 
  length 
  of 
  the 
  female, 
  

   measuring 
  0.08 
  inch. 
  

  

  ''^Remedies. 
  — 
  The 
  best 
  remedy 
  of 
  a 
  preventive 
  nature 
  against 
  further 
  

   ravages, 
  after 
  this 
  insect 
  has 
  made 
  its 
  appearance, 
  is 
  to 
  build 
  a 
  bonfire 
  

   upon 
  the 
  diseased 
  patch, 
  pull 
  up 
  the 
  onions 
  about, 
  and 
  throw 
  them 
  into 
  

   it. 
  By 
  thus 
  sacrificing 
  a 
  few 
  onions 
  at 
  the 
  outset, 
  the 
  evil 
  may 
  be 
  

   nipped 
  in 
  the 
  bud. 
  As 
  remedies 
  less 
  effective 
  we 
  would 
  recommend 
  

   showering 
  the 
  plants 
  with 
  strong 
  soap-suds, 
  or 
  sprinkling 
  them 
  with 
  

   sulphur, 
  or 
  the 
  use 
  of 
  a 
  solution 
  of 
  copperas, 
  such 
  as 
  is 
  used 
  in 
  killing 
  

   the 
  currant 
  saw-fly, 
  i. 
  e., 
  a 
  solution 
  of 
  a 
  pound 
  of 
  copperas 
  to 
  ten 
  gallons 
  

   of 
  water. 
  The 
  use 
  of 
  a 
  carbolate 
  of 
  lime 
  or 
  air-slaked 
  lime 
  may 
  also 
  

   be 
  recommended. 
  

  

  " 
  A 
  heavy 
  shower 
  of 
  rain 
  will 
  cause 
  them 
  to 
  disappear 
  for 
  a 
  while, 
  

   and 
  they 
  probably 
  only 
  appear 
  in 
  such 
  overwhelming 
  numbers 
  as 
  this 
  

   past 
  year 
  in 
  consequence 
  of 
  the 
  summer 
  being 
  an 
  unusually 
  dry 
  and 
  

   warm 
  one." 
  

  

  INSECTS 
  INJURING 
  THE 
  TURNIP. 
  

  

  The 
  Turnip 
  Flea-Beetle, 
  Haltica 
  (Orchestris) 
  striolata 
  JRigev. 
  — 
  Feeding 
  on 
  the 
  

   seed-leaves 
  in 
  the 
  spAng 
  and 
  later; 
  small, 
  yellow-striped, 
  flea-beetles. 
  In 
  June, 
  the 
  

   plants 
  die 
  from 
  the 
  attacks 
  of 
  the 
  grubs 
  which 
  live 
  in 
  the 
  roots. 
  

  

  This 
  is 
  a 
  very 
  annoying 
  little 
  beetle, 
  universally 
  abundant 
  in 
  gardens, 
  

   and 
  especially 
  injurious 
  to 
  the 
  seed-leaves 
  of 
  tbe 
  turnips, 
  cabbage, 
  and 
  

   other 
  garden-vegetables. 
  The 
  fullest 
  account 
  which 
  we 
  have 
  of 
  its 
  

   habits 
  is 
  that 
  given 
  by 
  Dr. 
  Shimer 
  in 
  the 
  American 
  Naturalist, 
  vol. 
  2, 
  p. 
  

   514, 
  which 
  I 
  copy 
  : 
  

  

  "This 
  beautiful 
  little 
  beetle, 
  also 
  called 
  striped 
  turnip-fly 
  {Haltica 
  

   striolata 
  Fabricius) 
  at 
  the 
  West, 
  is 
  well 
  known 
  and 
  abundant. 
  Every 
  

   gardener 
  is 
  conversant 
  with 
  the 
  fact 
  that, 
  like 
  fleas, 
  grasshoppers, 
  etc., 
  

   it 
  springs 
  away 
  to 
  a 
  great 
  distance 
  when 
  he 
  attempts 
  to 
  put 
  his 
  finger 
  

   upon 
  it. 
  It 
  appears 
  in 
  early 
  spring, 
  and 
  is 
  a 
  constant 
  annoyance 
  to 
  the 
  

   gardener 
  during 
  the 
  whole 
  summer. 
  

  

  " 
  From 
  my 
  notes 
  I 
  see 
  that 
  on 
  June 
  14, 
  1865, 
  I 
  put 
  a 
  number 
  of 
  the 
  

   larvsB 
  into 
  a 
  breeding-box, 
  with 
  a 
  supply 
  of 
  their 
  natural 
  food. 
  June 
  

   17 
  some 
  of 
  the 
  larvae 
  had 
  disappeared 
  beneath 
  the 
  ground. 
  July 
  4, 
  1 
  

   found 
  in 
  the 
  box 
  the 
  beetle. 
  This 
  gives 
  us 
  seventeen 
  days 
  from 
  the 
  

   time 
  the 
  larva 
  entered 
  the 
  ground, 
  having 
  ceased 
  eating, 
  until 
  I 
  ob- 
  

   tained 
  the 
  perfect 
  insect. 
  I 
  did 
  not 
  open 
  the 
  breeding-box 
  every 
  day,
