  lying 
  motionless

  They 
  are 
  thus 
  easily 
  captured 
  by 
  hand, 
  or 
  they 
  

   may 
  be 
  reached 
  by 
  the 
  usual

  insecticide

  to 
  the 
  

   beet

  Seven 
  species 
  of 
  American 
  snout-beetles 
  are 
  known 
  to 
  feed 
  upon 
  

   the 
  beet 
  leaf, 
  four 
  of 
  them 
  black 
  or 
  gray 
  with 
  broad 
  short 
  snouts, 
  and 
  

   three 
  minute 
  black 
  or 
  gray 
  beetles 
  with 
  long 
  slender 
  snouts. 
  Tanymecus 
  

   ■confertus 
  is 
  about 
  as 
  large 
  as 
  the 
  cucumber 
  beetle 
  and 
  one 
  fourth 
  of 
  an 
  

   inch 
  long. 
  It 
  is 
  gray, 
  mottled 
  and 
  speckled 
  with 
  brown, 
  and 
  washed 
  

   with 
  yellowish, 
  especially 
  on 
  the 
  subcylindrical 
  head 
  and 
  thorax. 
  

   Mpiccerus 
  imbricatus 
  (Fig. 
  68) 
  is 
  also 
  blackish 
  gray 
  with 
  oblique 
  pale- 
  

   gray 
  bands 
  upon 
  the 
  back. 
  It 
  is 
  three-eighths 
  of 
  an 
  inch 
  long, 
  plump 
  

   and 
  rounded, 
  and 
  much 
  heaviest 
  behind. 
  Two 
  species 
  of 
  Otiorhynchus 
  

   common 
  to 
  this 
  country 
  and 
  Europe 
  infest 
  the 
  sugar 
  beet 
  in 
  America, 
  

   O. 
  sulcatus 
  and 
  O. 
  singiilaris. 
  Siilcatus, 
  three 
  eighths 
  of 
  an 
  inch 
  long, 
  

   with 
  heavy 
  abdomen 
  and 
  small 
  distinct 
  thorax, 
  is 
  black, 
  without 
  trans- 
  

   verse 
  or 
  oblique 
  bands, 
  dotted 
  sparsely 
  with 
  minute 
  tufts 
  of 
  yellow 
  hairs; 
  

   singiilaris 
  is 
  similar 
  but 
  smaller, 
  five 
  sixteenths 
  of 
  an 
  inch 
  long, 
  with 
  rela- 
  

   tively 
  larger 
  thorax, 
  the 
  color 
  dull 
  dark 
  brown 
  sprinkled 
  with 
  yellowish. 
  

  

  Two 
  American 
  species 
  of 
  Centrinus 
  injure 
  the 
  leaf-stem 
  of 
  the 
  beet; 
  

   C. 
  penicellus, 
  which 
  is 
  about 
  an 
  eighth 
  of 
  an 
  inch 
  long, 
  brownish 
  gray, 
  

   usually 
  with 
  denuded 
  black 
  spots 
  near 
  the 
  tip 
  of 
  the 
  wing-cover, 
  and 
  C. 
  

   perscitiis 
  about 
  half 
  as 
  long 
  as 
  the 
  foregoing 
  and 
  a 
  much 
  darker 
  grayish- 
  

   brown. 
  A 
  minute 
  black 
  seed-weevil 
  (Apio/i) 
  also 
  occurs 
  on 
  sugar 
  beets.

  Imbricated 
  Snout-beetle. 
  

  

  EpicccrHS

  of 
  plants, 
  comprising 
  the 
  

   sugar 
  beet,
