  Mr. 
  G. 
  R. 
  Wateihouse's 
  Descriptions 
  of 
  

  

  with 
  Schonherr's 
  description 
  of 
  Prolopalus 
  Stephensii 
  so 
  perfectly 
  

   in 
  all 
  respects, 
  excepting 
  that 
  the 
  rostrum 
  is 
  not 
  crenulated 
  

   beneath, 
  and 
  the 
  anterior 
  legs 
  are 
  but 
  a 
  trifle 
  longer 
  than 
  the 
  

   others, 
  that 
  I 
  strongly 
  suspect 
  their 
  differences 
  merely 
  indicate 
  a 
  

   distinction 
  of 
  sex. 
  Furthermore, 
  I 
  possess 
  a 
  second 
  species 
  from 
  

   the 
  same 
  locality, 
  which 
  has 
  all 
  the 
  essential 
  characters 
  of 
  the 
  

   first 
  mentioned, 
  but 
  which 
  differs 
  in 
  the 
  relative 
  length 
  of 
  the 
  

   joints 
  of 
  the 
  antennae. 
  Now, 
  setting 
  aside 
  these 
  points, 
  there 
  are 
  

   so 
  many 
  other 
  characters 
  which 
  are 
  common 
  to 
  my 
  two 
  insects, 
  

   and 
  in 
  which 
  they 
  agree 
  with 
  the 
  definition 
  of 
  Protopalus 
  Ste- 
  

   phensii, 
  that 
  I 
  feel 
  satisfied 
  they 
  should 
  all 
  be 
  placed 
  in 
  the 
  same 
  

   genus; 
  in 
  which 
  case 
  the 
  generic 
  characters 
  will 
  require 
  to 
  be 
  

   modified.

   This 
  insect 
  very 
  much 
  resembles 
  the 
  insect 
  which 
  I 
  take 
  to 
  be 
  

   the 
  female 
  of 
  Protopalus 
  Stephensi't. 
  The 
  rostrum, 
  however, 
  is 
  

   less 
  curved 
  ; 
  the 
  keel 
  on 
  the 
  fore 
  part 
  of 
  the 
  thorax 
  rather 
  less 
  

   raised, 
  and 
  the 
  sutural 
  part 
  of 
  the 
  elytra 
  is 
  less 
  elevated, 
  though 
  

   still 
  considerably 
  humped. 
  The 
  eyes, 
  as 
  in 
  that 
  insect, 
  are 
  

   vertical, 
  lateral 
  (though 
  slightly 
  approximated), 
  and 
  directed 
  

   somewhat 
  forwards 
  ; 
  the 
  region 
  of 
  the 
  eye 
  above, 
  and 
  internally, 
  

   is 
  depressed 
  in 
  both 
  ; 
  but 
  in 
  the 
  present 
  insect, 
  the 
  depressed 
  

   areas 
  being 
  rather 
  broader, 
  there 
  is 
  no 
  mesial 
  ridge 
  left 
  as 
  in 
  

   P. 
  Stephensii. 
  The 
  sculpturing 
  of 
  the 
  elytra 
  accords 
  very 
  well 
  

   with 
  that 
  of 
  P. 
  Stephensii, 
  but 
  the 
  punctures 
  on 
  the 
  dorsal 
  surface 
  

   are 
  less 
  deep, 
  I 
  see 
  no 
  difference 
  in 
  the 
  general 
  outline, 
  except- 
  

   ing 
  those 
  diflferences 
  occasioned 
  by 
  the 
  thorax 
  and 
  elytra 
  being 
  

   rather 
  less 
  humped.
