  much 
  longer

  area 
  converging 
  

   behind

  (<^) 
  or 
  slightly 
  converging 
  ($) 
  from 
  the

  narrowing 
  rapidly

  Elytra 
  ovate, 
  much 
  broader 
  at 
  the 
  

   shoulders 
  than

  almost 
  parallel-sided

   declivity

  rather

   middle

  both 
  sexes 
  ; 
  the 
  scales 
  very 
  small, 
  nearly 
  circular 
  and 
  fairly 
  closely 
  placed, 
  

   interspersed 
  with 
  minute 
  recumbent 
  setae, 
  which 
  are 
  longer 
  and 
  form 
  regular 
  rows 
  

   posteriorly 
  ; 
  the 
  punctures 
  each 
  containing 
  a 
  small,

  In 
  spite 
  of 
  the 
  evanescent 
  prothoracic 
  vibrissae, 
  this 
  distinct 
  species 
  is 
  placed 
  

   in 
  Diaprepes 
  rather 
  than 
  in 
  Exophthalmod.es 
  on 
  account 
  of 
  the 
  second 
  joint 
  of 
  the 
  

   funicle 
  being 
  distinctly 
  longer 
  than 
  the 
  first, 
  and 
  because 
  the 
  mentum 
  bears 
  only 
  

   four 
  setae 
  in 
  a 
  transverse 
  row. 
  

  

  Mr. 
  Wolcott 
  states 
  that 
  the 
  adult 
  of 
  this 
  species 
  has 
  been 
  observed 
  feeding 
  on 
  

   the 
  leaves 
  of 
  pepper 
  {Capsicum).

  (Bull. 
  Soc. 
  Ent. 
  France 
  (5), 
  vi, 
  1876, 
  p. 
  ccxxvii) 
  described 
  this 
  species 
  

   as 
  a 
  Pachnaeus, 
  but 
  it 
  is 
  unquestionably 
  an 
  Exophthalmodes. 
  

  

  Mr. 
  G. 
  N. 
  Wolcott 
  notes 
  that 
  the 
  adults 
  attack 
  the 
  leaves 
  of 
  cotton 
  at 
  Isabella, 
  

   Porto 
  Rico, 
  but 
  states 
  that 
  the 
  species 
  is 
  more 
  abundant 
  on 
  citrus 
  trees.
