  than 
  to 
  yield 
  passively 
  to 
  the 
  scourge. 
  The 
  remarks 
  of 
  Mr. 
  Lockwood^ 
  

   that 
  we 
  reprint 
  in 
  our 
  account 
  of 
  the 
  goldsmith 
  beetle, 
  are 
  eminently 
  

   practical 
  as 
  applied 
  to 
  this 
  insect. 
  As 
  for 
  special 
  remedies, 
  we 
  have 
  

   none 
  to 
  propose. 
  Watchfulness 
  and 
  care 
  in 
  culture 
  are 
  better 
  than 
  any 
  

   special 
  nostrums. 
  

  

  " 
  Undoubtedly 
  the 
  natural 
  enemies 
  of 
  this 
  grub 
  are 
  many, 
  but 
  we 
  have 
  

   no 
  observations 
  bearing 
  on 
  this 
  point. 
  A 
  fungus 
  attacks 
  the 
  grubs 
  in 
  

   certain 
  seasons, 
  often 
  in 
  considerable 
  numbers. 
  We 
  have 
  received 
  speci- 
  

   mens 
  from 
  Missouri 
  of 
  dead 
  and 
  dried 
  grubs, 
  with 
  a 
  long 
  stem 
  growing 
  

   out 
  from 
  them, 
  the 
  result 
  of 
  the 
  attacks 
  of 
  this 
  fungus. 
  It 
  has 
  been 
  

   figured 
  by 
  Mr. 
  Eiley, 
  who 
  states 
  that 
  another 
  fungus 
  attacks 
  this 
  worm 
  

   in 
  Virginia. 
  It 
  is 
  well 
  known 
  that 
  caterpillars 
  and 
  even 
  the 
  common 
  

   housefly 
  are 
  sometimes 
  attacked 
  by 
  a 
  fungus 
  which 
  replaces 
  the 
  animal 
  

   portion 
  with 
  its 
  own 
  vegetable 
  substance. 
  

  

  "While 
  many 
  animals, 
  such 
  as 
  skunks, 
  moles, 
  crows, 
  etc., 
  prey 
  on 
  the 
  

   beetles, 
  the 
  only 
  insect-enemy 
  I 
  have 
  personally 
  observed 
  is 
  tlie 
  fierce 
  

   carnivoious 
  Calosoma 
  beetle 
  (C 
  calidum) 
  which 
  I 
  have 
  noticed 
  on 
  a 
  

   blueberry-bush 
  busily 
  engaged 
  in 
  tearing 
  open 
  the 
  hard, 
  horny 
  sides 
  of 
  

   one 
  of 
  these 
  beetles, 
  which 
  was 
  in 
  vain 
  struggling 
  to 
  escape 
  ; 
  on 
  taking 
  

   up 
  the 
  May 
  beetle 
  a 
  large 
  hole 
  had 
  been 
  eaten 
  into 
  its 
  side, 
  disclosing 
  

   the 
  viscera. 
  

  

  "Occasionally 
  the 
  beetles 
  appear 
  in 
  immense 
  numbers. 
  It 
  is 
  then 
  the 
  

   duty 
  of 
  the 
  agriculturist 
  to 
  pick 
  them 
  off 
  the 
  trees 
  and 
  burn 
  them. 
  If 
  

   the 
  French 
  take 
  the 
  pains 
  to 
  practice 
  hand-picking, 
  as 
  in 
  one 
  instance 
  

   'about 
  eighty 
  millions 
  were 
  collected 
  and 
  destroyed 
  in 
  a 
  single 
  portion 
  

   of 
  the 
  Lower 
  Seine' 
  (Eiley), 
  our 
  gardeners 
  can 
  afford 
  to 
  take 
  similar 
  

   pains. 
  

  

  "A 
  description 
  of 
  the 
  May 
  beetle 
  is 
  scarcely 
  necessary. 
  Fig. 
  10 
  (p. 
  

   720) 
  gives 
  a 
  good 
  idea 
  of 
  its 
  appearance 
  and 
  size. 
  It 
  is 
  bay-colored, 
  

   or 
  chestnut 
  and 
  brown, 
  with 
  yellowish 
  hairs 
  beneath, 
  and 
  is 
  nearly 
  an 
  

   inch 
  in 
  length. 
  Its 
  scientific 
  name 
  is 
  Lachnosterna 
  fusca, 
  or, 
  literally 
  

   translated, 
  the 
  brown 
  woolly- 
  breasted 
  beetle. 
  The 
  pupa 
  is 
  white." 
  

  

  The 
  Goldsmith 
  Beetle, 
  Cotalpa 
  lanigera, 
  Linn. 
  — 
  Feeding 
  on 
  the 
  roots 
  as 
  grub 
  ; 
  very 
  

   similar 
  to 
  that 
  of 
  the 
  June 
  beetle. 
  

  

  "We 
  also 
  have 
  in 
  the 
  Eastern 
  States 
  an 
  insect 
  allied 
  to 
  the 
  preceding, 
  

   and 
  with 
  much 
  the 
  same 
  habits, 
  both 
  in 
  the 
  adult 
  and 
  preparatory 
  states. 
  

   It 
  is 
  the 
  Cotalpa 
  lanigera. 
  It 
  is 
  nearly 
  an 
  inch 
  in 
  length, 
  bright 
  yellow 
  

   above, 
  with 
  a 
  golden 
  metallic 
  luster 
  on 
  the 
  head 
  and 
  thorax, 
  while 
  

   the 
  under 
  side 
  of 
  the 
  body 
  is 
  copper-colored, 
  and 
  densely 
  covered 
  with 
  

   white 
  hairs. 
  

  

  "Dr. 
  Harris 
  says 
  that 
  it 
  is 
  very 
  common 
  in 
  this 
  State, 
  remarking 
  that 
  

   it 
  begins 
  to 
  appear 
  in 
  Massachusetts 
  about 
  the 
  middle 
  of 
  May, 
  and 
  

   continues 
  generally 
  till 
  the 
  20th 
  of 
  June. 
  'In 
  the 
  morning 
  and 
  evening 
  

   twilight 
  they 
  come 
  forth 
  from 
  their 
  retreats, 
  and 
  fly 
  about 
  with 
  a 
  hum- 
  

   ming 
  and 
  rustling 
  sound 
  among 
  the 
  branches 
  of 
  trees, 
  the 
  tender 
  leaves 
  

   of 
  which 
  they 
  devour. 
  Pear-trees 
  are 
  particularly 
  subject 
  to 
  their 
  at- 
  

   tacks, 
  but 
  the 
  elm, 
  hickory, 
  poplar, 
  oak, 
  and 
  probably 
  also 
  other 
  kinds 
  

   of 
  trees, 
  are 
  frequented 
  and 
  injured 
  by 
  them.' 
  Dr. 
  Lock 
  wood 
  has 
  found 
  

   it 
  on 
  the 
  white 
  poplar 
  of 
  Europe, 
  the 
  sweet 
  gum, 
  and 
  has 
  seen 
  it 
  eating 
  

   the 
  Lawtou 
  blackberry. 
  He 
  adds 
  that 
  the 
  larvie 
  of 
  these 
  insects 
  are 
  

   not 
  known; 
  probably 
  they 
  live 
  in 
  the 
  ground 
  upon 
  the 
  roots 
  of 
  plants. 
  

  

  "It 
  has 
  remained 
  for 
  the 
  Eev. 
  Dr. 
  S. 
  Lockwood 
  to 
  discover 
  that 
  the 
  

   grub 
  or 
  larva 
  of 
  this 
  pretty 
  beetle 
  in 
  New 
  Jersey 
  devastates 
  strawberry- 
  

   beds, 
  the 
  larva 
  feeding 
  upon 
  the 
  roots, 
  in 
  the 
  same 
  manner 
  as 
  the 
  May
