  I 
  name 
  this 
  species 
  after 
  Mr. 
  Bates, 
  who 
  has 
  not 
  only 
  forwarded 
  

   to 
  England 
  numerous 
  collections 
  of 
  insects 
  and 
  objects 
  of 
  natural 
  

   history 
  from 
  the 
  Amazon 
  district 
  of 
  South 
  America, 
  but 
  has 
  also 
  

   furnished 
  us 
  with 
  interesting 
  observations 
  on 
  the 
  habits 
  and 
  geo-

  of 
  many

   The 
  two 
  insects, 
  which 
  I 
  assume 
  to 
  be 
  male 
  and 
  female, 
  I 
  

   received 
  in 
  a 
  series 
  of 
  Coleoptera 
  from 
  Minas 
  Geraes 
  : 
  they 
  are 
  

   pinned 
  with 
  the 
  same 
  pin, 
  and 
  hence, 
  in 
  all 
  probability 
  were 
  

   caught 
  together, 
  and 
  they 
  agree 
  perfectly 
  in 
  all 
  respects, 
  excepting 
  

   in 
  certain 
  peculiarities 
  of 
  structure 
  found 
  in 
  the 
  antennae, 
  rostrum 
  

   and 
  legs 
  — 
  in 
  fact 
  in 
  those 
  parts 
  which 
  are 
  known 
  to 
  vary 
  in 
  the 
  

   sexes. 
  The 
  new 
  genus 
  which 
  I 
  have 
  established 
  for 
  their 
  recep- 
  

   tion 
  should 
  in 
  my 
  opinion 
  be 
  placed 
  near 
  Loboderes. 
  The 
  female 
  

   is 
  remarkable 
  for 
  the 
  very 
  sudden 
  bending 
  under 
  of 
  the 
  rostrum 
  

   at 
  a 
  point 
  which 
  is 
  rather 
  behind 
  the 
  middle 
  ; 
  the 
  apical 
  portion 
  

   is 
  much 
  depressed, 
  the 
  basal 
  portion 
  is 
  incrassated 
  and 
  com- 
  

   pressed. 
  In 
  the 
  male 
  the 
  rostrum 
  is 
  much 
  arched, 
  rather 
  shorter 
  

   than 
  that 
  of 
  the 
  female, 
  but 
  still 
  fully 
  equal 
  to 
  the 
  head 
  and 
  

   thorax 
  in 
  length 
  ; 
  a 
  small 
  portion 
  at 
  the 
  ajjex, 
  being 
  about 
  one- 
  

  

  • 
  From 
  avouoioj, 
  dissimilar, 
  and 
  opflpov, 
  a 
  joint.
