  closely 
  but 
  not 
  coarsely 
  punctured, 
  the 
  latter 
  is 
  slightly 
  con- 
  

   vex 
  ; 
  the 
  prostemum, 
  keel 
  is 
  broad 
  and 
  tlat 
  and 
  truncate 
  at 
  

   botli 
  ends, 
  the 
  hiteral 
  striae 
  are 
  very 
  tine 
  and 
  feebly 
  sinuous 
  

   l)efore 
  the 
  coxte, 
  within 
  the 
  striai 
  and 
  parallel 
  to 
  them 
  is 
  a 
  

   very 
  shallow 
  channel, 
  more 
  conspicuous 
  than 
  the 
  striae 
  and 
  

   shorteneil 
  a 
  little 
  at 
  tlie 
  base; 
  the 
  mesosternum 
  is 
  transverse 
  

   and 
  narrow, 
  but 
  relatively 
  as 
  broad 
  as 
  in 
  Macrosternus 
  

   loftrtei, 
  anteriorly 
  it 
  is 
  almost 
  straight, 
  not 
  sinuous, 
  across 
  

   the 
  middle 
  there 
  is 
  a 
  bowed 
  stria, 
  somewhat 
  fine, 
  and 
  it 
  does 
  

   not 
  reach 
  the 
  outer 
  edges; 
  the 
  anterior 
  tibiae 
  are 
  10-11- 
  

   denticulate 
  and 
  all 
  the 
  tarsi 
  are 
  distinctly 
  hirsute.

  I 
  have 
  specimens 
  of 
  this 
  species 
  which 
  measure 
  11| 
  mm., 
  

   as 
  stated 
  in 
  the 
  jireauible 
  ; 
  the 
  mesosternal 
  marginal 
  stria 
  is 
  

   traceable 
  in 
  the 
  tyj)e 
  behind 
  the 
  emargination, 
  but 
  it 
  is 
  not 
  

   so 
  seen 
  in 
  other 
  examples. 
  The 
  localities 
  of 
  the 
  species 
  are 
  

   Kuniaon, 
  Sikkim, 
  and 
  Yunnan, 
  and 
  it 
  has 
  been 
  found 
  in 
  the 
  

   burrows 
  of 
  a 
  longicorn 
  in 
  willows.

  the

  lateral 
  stria 
  complete 
  and 
  

   rather 
  close

  the

  strongest 
  behind 
  the

  with 
  a 
  

   small

  ;

  the

  with 
  a 
  basal 
  puncture,

  and 
  

   sutural 
  dimidiate 
  ; 
  the 
  propygidium 
  is 
  rather 
  coarsely 
  and 
  

   somewhat 
  unevenly 
  punctate, 
  with 
  a 
  narrow 
  posterior 
  margin 
  

   smooth 
  ; 
  the 
  pygidium 
  has 
  similar 
  pmictures 
  transversely 
  

   placed 
  close 
  to 
  the 
  base, 
  leaving 
  the 
  apex 
  widely 
  smooth 
  ; 
  the 
  

   mesosternum 
  strongly 
  marginate, 
  stria 
  following 
  the 
  contour 
  

   of 
  the 
  emargination 
  and 
  continuing 
  laterally 
  to 
  the 
  base 
  of 
  

   the 
  metasternum, 
  suiface 
  of 
  the 
  sterna 
  microscopically 
  punc- 
  

   tulate

  the 
  anterior 
  tibiae 
  are 
  5-denticulate.
