  new 
  Species 
  of 
  Histeridae. 
  

  

  which 
  is 
  a 
  very 
  different 
  species 
  from 
  the 
  others 
  included 
  in 
  

   Phylloma 
  ; 
  and 
  whether 
  the 
  characters 
  which 
  are 
  now 
  held 
  to 
  

   separate 
  them 
  from 
  Lioderma 
  and 
  Hololepta 
  will 
  permanently 
  

   be 
  regarded 
  as 
  satisfactory, 
  it 
  seems 
  too 
  early 
  in 
  the 
  study 
  of 
  

   the 
  group 
  to 
  decide. 
  Paykuli 
  first 
  published 
  Hololepta 
  in 
  

   1811, 
  and 
  the 
  first 
  species 
  referred 
  to 
  the 
  genus 
  is 
  now 
  known 
  

   as 
  Platysoma 
  depressum, 
  F., 
  and 
  the 
  second 
  as 
  Paromalus 
  com- 
  

   planatus, 
  Panz. 
  ; 
  the 
  type 
  of 
  Hololepta 
  is 
  now 
  considered 
  to 
  be 
  

   plana, 
  Fuessly.

  This 
  fine 
  species 
  is 
  apparently 
  similar 
  to 
  P. 
  Hageni, 
  Mars., 
  

   a 
  species 
  I 
  know 
  only 
  by 
  description. 
  The 
  first 
  three 
  striae 
  

   of 
  the 
  elytra 
  are 
  wide, 
  the 
  epipleura 
  bicarinate, 
  the 
  anterior 
  

   angles 
  of 
  the 
  thorax 
  obtusely 
  produced, 
  and 
  all 
  the 
  tibiae 
  are 
  

   remarkably 
  dilated, 
  corresponding 
  in 
  this 
  respect 
  to 
  Htster 
  

   latitibiuS) 
  Mars. 
  In 
  P. 
  Hageni 
  the 
  mesosternal 
  stria 
  is 
  

   interrupted 
  and 
  the 
  insect 
  only 
  measures 
  4 
  millim.

  Platysoma 
  Gorharni, 
  n. 
  sp. 
  

  

  Oblongo-ovatum, 
  subdepressum, 
  nigro-nitidum 
  ; 
  fronte 
  tenuissime 
  

   punctulata, 
  leviter 
  depressa, 
  stria 
  sinnata 
  ; 
  pronoto 
  angulis 
  an- 
  

   ticis 
  valide 
  productis, 
  stria 
  integra 
  vix 
  profunde 
  impressa, 
  ante 
  

   scutellum 
  minute 
  foveolato 
  ;

  striis 
  l 
  a 
  -2 
  a 
  integris 
  validis, 
  3" 
  

   in 
  medio 
  parum 
  interrupta,4 
  a 
  apicali 
  ; 
  propygidio 
  biimpresso, 
  trans- 
  

   versim 
  punctato 
  ; 
  pygidio 
  grosse 
  et 
  dense 
  punctato, 
  posterius 
  

   marginato; 
  prosterno

  vix 
  angusto, 
  haud 
  striato; 
  meso- 
  

   sterno 
  leviter 
  sinuato, 
  stria 
  integra;

  This 
  species 
  is 
  one 
  third 
  smaller 
  than 
  P. 
  Murrayi, 
  Mars., 
  

   from 
  Old 
  Calabar, 
  and 
  the 
  mesosternal 
  stria 
  leaves 
  only 
  a 
  

   narrow 
  margin 
  in 
  the 
  first, 
  but 
  in 
  Murrayi 
  it 
  is 
  broad.
