  Dr. 
  Guy 
  A. 
  K. 
  Marshall, 
  Director 
  of 
  the 
  Imperial 
  Bureau 
  of 
  Entomology, 
  has 
  

   requested 
  me 
  to 
  indentify 
  four 
  specimens 
  of 
  a 
  Lygaeid 
  sent 
  to 
  him 
  by 
  Dr. 
  C. 
  J. 
  J. 
  

   Yan 
  Hall 
  from 
  Java, 
  where 
  it 
  was 
  found 
  among 
  stored 
  rice. 
  It 
  is 
  a 
  very 
  distinct 
  

   species 
  and 
  represents 
  a 
  new 
  genus 
  of 
  which 
  I 
  here 
  give 
  figure 
  and 
  description. 
  

  

  Fam. 
  LYGAEIDAE. 
  

  

  Subfam. 
  Aphaninae. 
  

  

  Div. 
  Myodocharia. 
  

   Ampera, 
  gen. 
  nov. 
  

   Head 
  about 
  as 
  long 
  as 
  anterior 
  lobe 
  of 
  pronotum 
  ; 
  first 
  joint 
  of 
  antennae 
  a 
  little 
  

   shorter 
  than 
  head 
  ; 
  pronotum 
  longer 
  than 
  broad, 
  transversely 
  constricted 
  before 
  

   middle, 
  collar 
  narrow, 
  anterior 
  lobe 
  distinctly 
  globose, 
  posterior 
  lobe 
  strongly 
  centrally 
  

   longitudinally 
  incised, 
  the 
  basal 
  lateral 
  angles 
  subnodulosely 
  prominent 
  ; 
  scutellum 
  

   broadly 
  subangulate 
  ; 
  rostrum 
  with 
  the 
  first 
  joint 
  slightly 
  passing 
  base 
  of 
  head 
  — 
  

   imperfectly 
  seen 
  in 
  carded 
  specimens 
  ; 
  anterior 
  femora 
  moderately 
  incrassated 
  ; 
  

   other 
  characters 
  generally 
  as 
  in 
  Pamem, 
  from 
  which 
  it 
  principally 
  differs 
  by 
  the 
  

   structure 
  of 
  the 
  pronotum 
  and 
  scutellum. 
  

  

  Ampera 
  intrusa, 
  sp. 
  nov. 
  (fig. 
  l). 
  

  

  Head, 
  anterior 
  lobe 
  of 
  pronotum 
  and 
  scutellum, 
  black 
  or 
  blackish, 
  posterior 
  frontal 
  

   lobe 
  more 
  castaneous 
  ; 
  corium 
  more 
  or 
  less 
  stramineous, 
  the 
  apical 
  area 
  more 
  or 
  less 
  

   inf 
  uscate 
  ; 
  membrane 
  black 
  or 
  piceous, 
  body 
  beneath 
  blackish 
  ;

  longer 
  than

   passing 
  abdominal
