  In 
  a 
  recent 
  paper 
  I 
  referred 
  to 
  the 
  genus 
  Dicrwodon 
  an 
  

   unnamed 
  insect 
  from 
  Guatemala 
  placed 
  by 
  H. 
  W. 
  Bates 
  in 
  

   Coelodes. 
  Having 
  since 
  seen 
  two 
  further 
  specimens 
  from 
  

   Herr 
  0. 
  Felsche's 
  collection, 
  I 
  take 
  this 
  opportunity 
  of 
  

   describing 
  the 
  species. 
  

  

  Dicrceodon 
  punctatum, 
  sp. 
  n. 
  

  

  Testaceus, 
  capite, 
  prothorace 
  scutelloque 
  interdura 
  obscurioribus 
  ; 
  

   capite 
  parce 
  irregulariter 
  punctato 
  ; 
  prothorace 
  sat 
  grosse 
  

   ir 
  regular! 
  ter 
  punctato, 
  valde 
  transverso, 
  fere 
  somicirculari, 
  late- 
  

   ribus 
  valde 
  arcuatis, 
  angulis 
  posticis 
  distinctis, 
  obtusis; 
  scutello 
  

   antice 
  punctato, 
  postice 
  laevi 
  ; 
  elytris 
  grosse 
  seriato-punctatis, 
  

   serie 
  juxta-suturali 
  impresso, 
  reliquis 
  vix 
  impressis, 
  margini- 
  

   bus 
  externis 
  antice 
  parce 
  sed 
  longissime 
  ciliatis, 
  apicibus 
  

   excisis, 
  biangulatis 
  ; 
  tibiis 
  anticis 
  longe 
  bidentatis, 
  denteque 
  

   tertio 
  brevissimo 
  obtuso, 
  tibiis 
  posticis 
  apice 
  dilatatis, 
  tarsis 
  quani 
  

   tibiis 
  haud 
  longioribus, 
  pedum 
  posticorura 
  calcare 
  superiore 
  longo, 
  

   valde 
  inquinato; 
  mandibulis 
  dente 
  acuto 
  apicali 
  alteroque 
  minus 
  

   acuto 
  pone 
  apicem 
  munitis. 
  

  

  Long.

  mm. 
  ;

  mm.

  The 
  three 
  specimens 
  I 
  have 
  examined 
  appear 
  lo 
  be 
  females, 
  

   as 
  they 
  agree 
  in 
  the 
  form 
  of 
  the 
  mandibles, 
  the 
  dilated 
  hind 
  

   tibiae, 
  short 
  tarsi, 
  and 
  very 
  long 
  elytral 
  fringe 
  with 
  the 
  

   female 
  of 
  Dicrceodon 
  {Aporolaus) 
  Jlmbriatus, 
  Bates. 
  It 
  is 
  a 
  

   much 
  smaller 
  species, 
  of 
  nearly 
  the 
  same 
  size 
  as 
  D. 
  basalt's, 
  

   Westw. 
  It 
  differs 
  from 
  both 
  in 
  the 
  much 
  larger 
  punctures 
  

   of 
  the 
  elytra, 
  arranged 
  in 
  rows 
  which 
  are 
  only 
  half 
  as 
  nume- 
  

   rous. 
  The 
  strong 
  hooked 
  spurs 
  of 
  the 
  hind 
  legs 
  are 
  very 
  

   remarkable. 
  

  

  In 
  the 
  paper 
  referred 
  to 
  above 
  I 
  remarked 
  that 
  the 
  genus 
  

   llapalonychus 
  was 
  exceptional 
  in 
  being 
  apparently 
  confined 
  

   to 
  the 
  West-Indian 
  islands. 
  The 
  species 
  here 
  described 
  

   dissipates 
  that 
  idea, 
  having 
  the 
  unexpected 
  habitat 
  of 
  

   Paraguay. 
  

  

  Hapalonychus 
  pusillus, 
  sp. 
  n. 
  

  

  Niger, 
  nitidus, 
  sat 
  elongatus, 
  prothoracis 
  et 
  elytrorum 
  marginibus 
  

   externis 
  longe 
  ciliatis 
  ; 
  capite 
  paulo 
  impresso, 
  grosse 
  punctato, 
  

   labro 
  angusto, 
  elliptico 
  ; 
  prothorace 
  valde 
  transverso, 
  fortiter 
  

   irregulariter 
  punctato, 
  lateribus 
  antice 
  valde 
  contractis, 
  postice
