  except 
  a 
  yellow 
  median 
  spot, 
  spots 
  on 
  the 
  pleurae 
  above 
  the 
  

   coxae, 
  the 
  margins 
  of 
  the 
  scutellum 
  and 
  postscutellum, 
  the 
  

   mesosternum, 
  a 
  triangular 
  spot 
  at 
  the 
  apex 
  of 
  the 
  median 
  

   Begmeutj 
  and 
  the 
  base 
  and 
  apex 
  of 
  each 
  of 
  the 
  abdominal 
  

  

  segments 
  rather 
  broadly 
  above, 
  more 
  narrowly 
  beneath, 
  dull 
  

   ferruginous. 
  Wings 
  hyaline; 
  uervures 
  fuscous, 
  testaceous 
  

   at 
  the 
  extreme 
  base.

  As 
  in 
  the 
  female 
  ; 
  but 
  the 
  margins 
  of 
  segments 
  4-7 
  

   are 
  black 
  instead 
  of 
  ferruginous. 
  The 
  first 
  recurrent 
  nervurc 
  

   is 
  received 
  at 
  the 
  middle 
  of 
  the 
  second 
  cubital 
  cell, 
  the 
  

   second 
  at 
  one-quarter 
  from 
  the 
  base 
  of 
  the 
  third 
  cubital 
  cell. 
  

   The 
  submedian 
  cell 
  is 
  no 
  longer 
  than 
  the 
  median. 
  In 
  both 
  

   sexes 
  the 
  mandibles 
  are 
  black 
  at 
  the 
  apex.

  Very 
  near 
  S. 
  glasunovii, 
  Mor., 
  but 
  in 
  the 
  present 
  species 
  

   the 
  second 
  joint 
  of 
  the 
  flagellum 
  is 
  distinctly 
  longer 
  than 
  the 
  

   third, 
  the 
  teguhe 
  are 
  less 
  strongly 
  punctured, 
  the 
  metaplcune 
  

   are 
  not 
  striated, 
  the 
  colour 
  also 
  differs 
  considerably. 
  1 
  have 
  

   not 
  seen 
  specimens 
  of 
  glasunovii, 
  and 
  it 
  is 
  possible 
  that 
  the 
  

   differences 
  may 
  prove 
  to 
  be 
  of 
  subspeeitic 
  rather 
  than 
  of 
  

   full 
  specific 
  importance. 
  The 
  slight 
  differences 
  in 
  ncuration 
  

   between 
  the 
  sexes 
  are 
  remarkable.
