  the 
  non-possession 
  of 
  wings, 
  out 
  in 
  their 
  antennae 
  being 
  but 
  four 
  instead 
  

   of 
  tive-jointed, 
  as 
  they 
  afterward 
  become." 
  The 
  mature 
  bug 
  is 
  prettily 
  marJsed 
  with 
  

   polished 
  orange 
  and 
  blue-black, 
  the 
  relative 
  proportion 
  of 
  the 
  two 
  colors 
  being 
  very 
  

   variable 
  and 
  the 
  orange 
  inclining 
  either 
  to 
  yellow 
  or 
  red 
  (Riley). 
  Uhler 
  says 
  that 
  

   various 
  patterns 
  of 
  markings 
  and 
  colors, 
  ranging 
  from 
  yellow 
  to 
  steel-blue, 
  are 
  con- 
  

   spicuously 
  exhibited 
  in

  pretty

  unstable

  pernicious 
  insect. 
  

  

  Remedy.

  The

  hand-

  The 
  Colorado 
  Green 
  Flea-Beetle, 
  Orchestris 
  alUonica 
  Le 
  Conte. 
  — 
  Very 
  abundant 
  

   in 
  Colorado 
  at 
  different 
  elevations, 
  eating 
  holes 
  in 
  the 
  leaves 
  of 
  cabbages 
  and 
  radishes,

  ; 
  a 
  small 
  green 
  flea-beetle, 
  about 
  one-tenth 
  of 
  a 
  line 
  in 
  length. 
  

  

  This 
  little 
  flea-beetle 
  is 
  very 
  abundant 
  in 
  Colorado 
  at 
  all 
  elevations, 
  

   and 
  is 
  destined 
  to 
  become 
  a 
  great 
  plague. 
  At 
  Denver 
  it 
  was 
  very 
  

   abundant 
  in 
  June 
  and 
  July 
  on 
  cruciferous 
  plants, 
  espe- 
  

   cially 
  the 
  cabbage 
  and 
  radish, 
  eating 
  holes 
  in 
  the 
  leaves. 
  

   At 
  Golden 
  it 
  was 
  extremely 
  abundant 
  on 
  young 
  cabbage 
  

   and 
  radishes. 
  At 
  Idaho 
  it 
  was 
  abundant 
  on 
  young 
  tur- 
  

   nips 
  and 
  potatoes, 
  eating 
  holes 
  in 
  the 
  leaves. 
  At 
  Manitou 
  

   these 
  little 
  beetles 
  swarmed 
  on 
  beds 
  of 
  radishes 
  and 
  cab- 
  

   bages; 
  the 
  plants 
  were 
  small, 
  just 
  coming 
  up, 
  and 
  these 
  

   little 
  pests 
  were 
  eating 
  them 
  up. 
  Multitudes 
  of 
  them 
  were 
  

   found 
  on 
  the 
  summit 
  of 
  Pike's 
  Peak, 
  on 
  the 
  grass 
  and 
  fig.

  Colo- 
  

   Alpine 
  flowers, 
  among 
  the 
  patches 
  of

  having 
  prob- 
  rado 
  green 
  

   ably 
  been 
  borne 
  up 
  from 
  the 
  plains 
  and 
  parks 
  below 
  by 
  Flea-Beetle, 
  

   currents 
  of 
  air. 
  Its 
  habits 
  are 
  probably 
  nearly 
  identical 
  with 
  those 
  of 
  

   the 
  turnip 
  flea-beetle, 
  to 
  the 
  account 
  of 
  which 
  the 
  reader 
  is 
  referred. 
  

   The 
  larva 
  is 
  to 
  be 
  looked 
  for 
  in 
  the 
  roots 
  of 
  the 
  plants 
  on 
  which 
  it 
  

   feeds. 
  

  

  Desmption.— 
  It 
  is 
  a 
  very 
  small, 
  green 
  beetle, 
  not 
  quite 
  one 
  line 
  in

  ; 
  uniformly 
  

   deep, 
  shining 
  olive-green. 
  The 
  surface 
  of 
  the 
  body, 
  especially 
  the 
  wing-covers, 
  is 
  

   coarsely 
  punctured 
  with 
  little 
  pits. 
  Antennse

  The 
  Pitchy-Legged 
  Weevil, 
  Otiorhynchus 
  picipes 
  (Fabricius). 
  — 
  Damaging 
  young 
  

   cabbages, 
  kale, 
  broccoli, 
  and 
  other 
  garden-vegetables 
  j 
  a 
  pitchy-brown 
  weevil, 
  a 
  quarter 
  

   of 
  an 
  inch 
  in 
  length. 
  

  

  A 
  weevil 
  has 
  for 
  several 
  years 
  been 
  not 
  uncommon 
  in 
  Essex 
  County, 
  

   Massachusetts, 
  which 
  in 
  England, 
  from 
  which 
  it 
  has 
  been 
  imported, 
  is 
  

   often, 
  as 
  Mr. 
  Curtis 
  says, 
  "a 
  dreadful 
  pest 
  in 
  gardens, 
  committing 
  sad 
  

   ravages 
  on 
  vines 
  in 
  hot-houses 
  and 
  on 
  wall-fruit, 
  during 
  the 
  night, 
  when 
  

   they 
  emerge 
  from 
  their 
  hiding-places 
  in 
  old 
  walls, 
  from 
  under 
  the 
  bark, 
  

   and 
  clods 
  of 
  earth, 
  to 
  revel 
  upon 
  the 
  branches 
  of 
  the 
  new 
  wood 
  in 
  

   April, 
  or 
  to 
  feed 
  upon 
  the 
  young 
  shoots, 
  which 
  soon 
  become 
  black. 
  

   They 
  likewise 
  injure 
  raspberry 
  plants 
  in 
  spring, 
  by 
  eating 
  through 
  the 
  

   flowering 
  stems 
  and 
  leaves, 
  and 
  they 
  nibble 
  off 
  the 
  bark, 
  and 
  eat 
  out 
  

   the 
  buds 
  of 
  apple 
  and 
  pear 
  trees 
  as 
  early 
  as 
  February 
  or 
  March." 
  But 
  

   they 
  are 
  said 
  by 
  Curtis 
  to 
  do 
  still 
  more 
  damage 
  to 
  pease, 
  turnips, 
  and 
  

   young 
  winter-plants, 
  as 
  savoy, 
  kale, 
  broccoli, 
  etc. 
  

  

  I 
  have 
  detected 
  this 
  weevil 
  on 
  the 
  beach-pea 
  during 
  the 
  last 
  week 
  in 
  

   July 
  at 
  Salem, 
  Mass., 
  and 
  it 
  is 
  not 
  uncommon 
  in 
  gardens, 
  and 
  even, 
  if 
  

   I 
  am 
  not 
  mistaken 
  as 
  to 
  the 
  identity 
  of 
  the 
  insect,
