  Mr.

  W. 
  Bates' 
  additions 
  to 
  the 
  

  

  Selenophorus 
  tarsalis, 
  Putz. 
  

  

  Var. 
  liosomus. 
  

  

  Differs 
  from 
  the 
  type-form, 
  as 
  found 
  in 
  Mexico 
  and 
  

   Guatemala, 
  only 
  in 
  its 
  larger 
  size 
  and 
  the 
  more 
  polished 
  

   and 
  more 
  strongly 
  iridescent 
  surface. 
  The 
  colour 
  ia 
  

   pieeous, 
  metallic 
  above, 
  inclining 
  to 
  green 
  on 
  the 
  head 
  

   and 
  thorax, 
  and 
  brownish 
  coppery 
  on 
  the 
  elytra. 
  The 
  

   sides 
  of 
  the 
  thorax 
  are 
  arcuated, 
  much 
  more 
  strongly 
  so 
  

   than 
  in 
  S. 
  splendidus 
  (Putz.), 
  the 
  greatest 
  width 
  being 
  

   just 
  before 
  the 
  middle 
  ; 
  the 
  sides 
  become 
  less 
  arcuated, 
  

   almost 
  straight, 
  towards 
  the 
  base, 
  and 
  the 
  hind 
  angles 
  

   are 
  well-pronounced, 
  though 
  obtuse 
  ; 
  the 
  base 
  has 
  

   scarcely 
  any 
  punctuation. 
  The 
  interstices 
  of 
  the 
  elytra 
  

   are 
  smooth 
  to 
  the 
  apex, 
  except 
  the 
  9th 
  (marginal) 
  and 
  

   the 
  edge 
  of 
  the 
  8th, 
  which 
  are 
  finely 
  punctured. 
  The 
  

   antennae, 
  parts 
  of 
  mouth 
  and 
  legs, 
  are 
  tawny 
  red, 
  the 
  

   femora 
  in 
  some 
  examples 
  darker 
  and 
  pieeous. 
  Long. 
  

   10 
  millim.

  Selenophorus 
  hradycelloides. 
  

  

  Parvus, 
  nitidus, 
  rufo-testaceus, 
  capite 
  postice, 
  maculis 
  thoracis 
  

   discoidalibus 
  duabus 
  elytrisque 
  interstitiis 
  2 
  —

  castaneo-fuscis 
  vix 
  

   metallicis 
  ; 
  antennis 
  articulis 
  3 
  — 
  4 
  nigro-fuscis 
  ; 
  thorace 
  sub- 
  

   cordato-quadrato, 
  postice 
  simiato-angustato 
  angulis 
  posticis 
  rectis, 
  

   basi 
  utrinque 
  planato, 
  punctulato 
  ; 
  elytris 
  acute 
  striatis, 
  apice 
  

   oblique 
  modice 
  sinuatis, 
  interstitiis 
  planis 
  (apice 
  vix 
  convexioribus) 
  

   3io, 
  5to 
  et 
  7mo 
  seriatim 
  punctatis.

  Tabasco 
  (Hoge). 
  

  

  This 
  small 
  and 
  distinct 
  species 
  is 
  not 
  recognisable 
  as 
  

   a 
  member 
  of 
  the 
  genus 
  Selenophorus 
  at 
  first 
  sight 
  ; 
  the 
  

   shape 
  and 
  style 
  of 
  coloration 
  being 
  rather 
  those 
  pre- 
  

   vailing 
  in 
  Acupalpus 
  and 
  Brady 
  cellus. 
  The 
  maxillary 
  

   palpi 
  also 
  are 
  more 
  gradually 
  pointed 
  than 
  in 
  the 
  

   restricted 
  Harpalince 
  group, 
  but 
  the 
  rounded 
  punctiform 
  

   frontal 
  foveas, 
  the 
  edentate 
  mentum, 
  and 
  the 
  triseriately 
  

   punctured 
  elytra 
  show 
  that 
  the 
  species 
  is 
  a 
  Seleno- 
  

   phorus. 
  The 
  punctures 
  are 
  very 
  distinct 
  and 
  deep, 
  

   but 
  few 
  in 
  number 
  ; 
  the 
  row 
  of 
  six 
  on 
  the 
  3rd 
  inter- 
  

   stice 
  lying 
  near 
  the 
  2nd 
  stria, 
  that 
  of 
  the 
  5th 
  (five 
  in 
  

   number) 
  near 
  the 
  6th 
  and 
  that 
  of 
  the 
  7th 
  (consisting
