   both

  and 
  closely 
  set 
  with 
  flattened, 
  transversely

  (H.

   Described 
  from 
  21 
  specimens. 
  

  

  The 
  nearest 
  allies 
  of 
  this 
  insect 
  are 
  the 
  Brazilian 
  species, 
  C. 
  undulatns, 
  Gyl., 
  and 
  

   C. 
  parens, 
  Fhs., 
  especially 
  the 
  latter, 
  which 
  is 
  very 
  similar 
  in 
  its 
  general 
  form 
  

   and 
  sculpturing 
  ; 
  but 
  it 
  lacks 
  the 
  thoracic 
  markings 
  and 
  the 
  transverse 
  bands 
  on 
  

   the 
  elytra, 
  when 
  present, 
  are 
  very 
  indefinite 
  and 
  irregular, 
  the 
  basal 
  one 
  lying 
  actually 
  

   on 
  the 
  basal 
  margin. 
  But 
  both 
  these 
  species 
  differ, 
  inter 
  alia, 
  in 
  the 
  following 
  

   structural 
  characters 
  : 
  the 
  prosternum 
  is 
  not 
  tuberculate 
  between 
  the 
  coxae 
  ; 
  the 
  

   front 
  femora 
  bear 
  no 
  tooth 
  in 
  either 
  sex 
  ;• 
  the 
  front 
  tibiae 
  in 
  the 
  c? 
  have 
  no 
  median 
  

   internal 
  tooth 
  ; 
  and 
  the 
  front 
  coxae 
  in 
  the 
  same 
  sex 
  each 
  bear 
  a 
  stout 
  spur. 
  

  

  The 
  species 
  is 
  dedicated 
  to 
  Sir 
  Francis 
  Watts, 
  K.G.M.G., 
  Commissioner 
  of 
  the 
  

   Imperial 
  Department 
  of 
  Agriculture 
  for 
  the 
  West 
  Indies, 
  who 
  forwarded 
  specimens 
  

   with 
  the 
  information 
  that 
  the 
  insect 
  was 
  doing 
  appreciable 
  damage 
  to 
  pineapples 
  

   in 
  Grenada. 
  

  

  I 
  am 
  indebted 
  to 
  Mr. 
  H. 
  A. 
  Ballou, 
  Entomologist 
  to 
  the 
  Department, 
  for 
  examples 
  

   of 
  the 
  larvae 
  (fig. 
  2) 
  and 
  for 
  the 
  following 
  interesting 
  notes 
  on 
  the 
  species.

  The 
  pineapple 
  weevil 
  was 
  discovered 
  by 
  Mr. 
  R. 
  O. 
  Williams, 
  Agricultural 
  

   Superintendent, 
  in 
  May 
  1920, 
  on

  peasant 
  holding 
  at 
  Grantons,
