  Mr. 
  Lewis 
  met 
  with 
  a 
  specimen 
  at 
  Kioto 
  on 
  the 
  4th 
  July, 
  

   1881, 
  differing 
  from 
  a 
  Ceylonese 
  example 
  only 
  in 
  possessing 
  

   a 
  slight 
  depression 
  on 
  the 
  front 
  of 
  the 
  head.

  The 
  Japanese 
  individuals 
  of 
  this 
  widely 
  distributed 
  and 
  

   variable 
  species 
  are 
  far 
  from 
  agreeing 
  exactly 
  with 
  our 
  

   European 
  varieties 
  ; 
  they 
  are 
  remarkably 
  elongate, 
  with 
  

   narrow 
  head, 
  slender 
  oblong 
  thorax, 
  which 
  is 
  not 
  narrowed 
  in 
  

   front, 
  and 
  brassy 
  elytra 
  ; 
  amongst 
  the 
  small 
  series 
  before 
  me 
  

   there 
  are, 
  however, 
  some 
  individuals 
  which 
  indicate 
  that 
  

   there 
  will 
  prove 
  to 
  be 
  more 
  than 
  one 
  variety 
  or 
  form 
  in 
  

   Japan.

  This 
  species 
  belongs 
  to 
  the 
  subgenus 
  Babigus, 
  Rey, 
  and 
  

   is 
  allied 
  to 
  the 
  European 
  P. 
  tenuis 
  ; 
  but 
  it 
  is 
  smaller, 
  of 
  a 
  

   different 
  colour, 
  and 
  lias 
  the 
  antennae 
  yellow. 
  Unlike 
  the 
  

   European 
  species, 
  it 
  is 
  extremely 
  variable. 
  Sometimes 
  the 
  

   thorax 
  and 
  head 
  are 
  of 
  one 
  piceous 
  black 
  colour, 
  sometimes 
  

   the 
  head 
  is 
  quite 
  black 
  and 
  the 
  thorax 
  bright 
  red, 
  and 
  some- 
  

   times 
  the 
  elytra 
  are 
  obscure 
  red 
  ; 
  the 
  elytra 
  are 
  sometimes 
  

   much 
  shorter 
  than 
  the 
  thorax, 
  but 
  in 
  some 
  cases 
  are 
  about 
  equal 
  

   to 
  them 
  in 
  length 
  ; 
  the 
  number 
  of 
  punctures 
  in 
  the 
  dorsal 
  series 
  

   is 
  apparently 
  as 
  often 
  five 
  as 
  six. 
  The 
  fine 
  pubescence 
  on 
  

   the 
  hind 
  body 
  is 
  somewhat 
  flavescent 
  in 
  colour. 
  The 
  front 
  

   tarsi 
  of 
  the 
  male 
  are 
  only 
  moderately 
  dilated, 
  and 
  the 
  last 
  

   ventral 
  plate 
  has 
  a 
  broad 
  shallow 
  emargination 
  preceded 
  by 
  

   a 
  triangular 
  membrane. 
  

  

  Found 
  in 
  several 
  localities, 
  but 
  apparently 
  rare.
