  A 
  New 
  M.exico 
  correspondent 
  of 
  the 
  U. 
  S. 
  De- 
  

   partment 
  of 
  Agriculture, 
  Division 
  of 
  Entomology, 
  * 
  says 
  the 
  beetles 
  lay 
  

   their 
  eggs 
  on 
  the 
  under 
  side 
  of 
  the 
  sugar 
  beet, 
  these 
  hatching 
  in 
  about 
  

   six 
  days. 
  The 
  larv?e 
  feed 
  on 
  the 
  beet 
  leaf. 
  Hundreds 
  occurred 
  on 
  a 
  

   single 
  plant, 
  causing 
  it 
  to 
  shrivel 
  and 
  die. 
  After 
  about 
  nine 
  or 
  ten 
  

   days, 
  they 
  enter 
  the 
  earth, 
  change 
  to 
  pup?e, 
  and 
  a 
  few 
  days 
  later 
  the 
  

   beetles 
  appear. 
  

  

  Af 
  anoxia 
  consputa 
  injures 
  sugar 
  beets 
  to 
  a 
  serious 
  extent 
  in 
  the 
  

   West. 
  It 
  ranges 
  from 
  Arizona 
  and 
  California 
  northward 
  to 
  the 
  Dakotas 
  

   and 
  the 
  northwestern 
  United 
  States. 
  It 
  is 
  quite 
  common 
  on 
  the 
  Pacific 
  

   coast, 
  and 
  seems 
  to 
  be 
  the 
  most 
  troublesome 
  beet 
  pest 
  in 
  Oregon. 
  

   These 
  beetles 
  eat 
  small 
  holes 
  in 
  the 
  leaf, 
  sometimes 
  leaving 
  only 
  a 
  net- 
  

   work 
  of 
  veins, 
  checking 
  the 
  growth 
  of 
  the 
  beet 
  plants, 
  or 
  killing 
  them 
  

   entirely. 
  An 
  application 
  that 
  was 
  successful 
  in 
  killing 
  these 
  and 
  other 
  

   leaf-feeding 
  insects 
  was 
  composed 
  of 
  half 
  a 
  pound 
  of 
  Paris 
  green 
  and 
  

   three 
  pounds 
  of 
  whale-oil 
  soap 
  in 
  fifty 
  gallons 
  of 
  water. 
  The 
  whale-oil 
  

   soap 
  was 
  probably 
  necessary 
  to 
  make 
  the 
  spray 
  adhere 
  to 
  the 
  plants. 
  

  

  GRASSHOPPERS. 
  

  

  Acrididce 
  and 
  Loctistida. 
  

  

  Notwithstanding 
  the 
  abundance 
  of 
  grasshoppers 
  everywhere 
  in 
  beet 
  

   fields, 
  and 
  the 
  considerable 
  list 
  of 
  species 
  occurring 
  there, 
  their 
  injuries 
  

   to 
  beets 
  are 
  not 
  usually 
  serious 
  but 
  are 
  mainly 
  confined 
  to 
  fields 
  adjacent 
  

   to 
  grass 
  lands 
  in 
  which 
  grasshoppers 
  have 
  bred 
  in 
  extraordinary 
  num- 
  

   bers. 
  An 
  instance 
  of 
  injury 
  under 
  these 
  conditions 
  came 
  to 
  our 
  notice 
  

   in 
  July, 
  1899. 
  One 
  of 
  the 
  fields 
  of 
  the 
  Illinois 
  Sugar 
  Refining 
  Company, 
  

   near 
  Pekin, 
  111., 
  was 
  considerably 
  injured 
  at 
  this 
  time 
  by 
  the 
  common 
  

   red-legged 
  grasshopper 
  (^Pezotettix 
  feniur-rubrum 
  — 
  Fig. 
  55), 
  which 
  ate 
  

   large 
  irregular 
  holes 
  in 
  the 
  leaves, 
  or 
  cut 
  broad 
  deep 
  notches 
  out 
  of 
  

   their 
  edges, 
  leaving 
  only 
  the 
  larger 
  veins 
  to 
  hold 
  the 
  leaves 
  together. 
  

  

  The 
  two 
  families 
  commonly 
  confused 
  under 
  the 
  general 
  name 
  of 
  

   " 
  grasshopper 
  " 
  may 
  be 
  easily 
  distinguished 
  by 
  their 
  antennae. 
  Those 
  of 
  

   the 
  meadow 
  grasshopper 
  (^Locustidce) 
  are 
  many-jointed, 
  slender, 
  and 
  

   much 
  longer 
  than 
  the 
  body 
  (Fig. 
  57, 
  59) 
  and 
  those 
  of 
  the 
  Acrididce 
  

   (often 
  called 
  locusts 
  by 
  entomologists) 
  are 
  much 
  shorter 
  than 
  the 
  body 
  

   and 
  comparatively 
  thick 
  (Fig. 
  50 
  — 
  56). 
  The 
  female 
  of 
  the 
  Locustidoi 
  

   (Fig. 
  57) 
  has 
  projecting 
  backward 
  from 
  the 
  tip 
  of 
  the 
  abdomen 
  a 
  com- 
  

   pressed 
  sword-shaped 
  organ 
  which 
  is 
  used 
  for 
  placing 
  the 
  egg 
  in 
  or 
  

   about 
  plants, 
  while 
  the 
  female 
  of 
  the 
  Acridida; 
  has 
  at 
  the 
  end 
  of 
  the 
  

   abdomen 
  four 
  stout 
  blunt 
  structures 
  with 
  curved 
  tips 
  which, 
  brought 
  

   together 
  on 
  the 
  middle 
  line, 
  form 
  a 
  thick 
  conical 
  tip 
  to 
  the 
  body, 
  used 
  

   in 
  forcing 
  the 
  abdomen 
  into 
  the 
  earth 
  for 
  the 
  deposit 
  of 
  the 
  t^g 
  mass.
