  p.

  Described 
  from 
  a 
  single 
  female 
  which 
  remains 
  the 
  unique 
  repre- 
  

   sentative 
  of 
  the 
  form. 
  This 
  specimen, 
  now 
  in 
  the 
  Museum 
  of 
  Com- 
  

   parative 
  Zoology 
  has 
  been 
  studied 
  in 
  the 
  course 
  of 
  the 
  present 
  revi- 
  

   sion. 
  The 
  carinae 
  of 
  seventh 
  tergite, 
  not 
  mentioned 
  in 
  original 
  

   description 
  are 
  very 
  distinctive, 
  grouping 
  the 
  species 
  with 
  the 
  new 
  

   form 
  banksi 
  described 
  below. 
  The 
  coloration 
  is 
  scarcely 
  different 
  

   from 
  that 
  of 
  E. 
  brevipennis; 
  however 
  it 
  was 
  noted 
  that 
  the 
  mid 
  and 
  

   hind 
  tibiae 
  are 
  entirely 
  pale 
  except 
  for 
  a 
  sub-basal 
  dusky 
  band 
  on 
  

   each. 
  Approximate 
  measurements 
  are: 
  Length 
  of 
  head 
  and 
  body 
  

   together 
  29 
  mm. 
  ; 
  of 
  front 
  coxa, 
  5 
  mm. 
  ; 
  of 
  front 
  femur 
  7.5 
  mm. 
  

  

  EMESAYA 
  BANKSI, 
  new 
  species. 
  

  

  Agrees 
  with 
  E. 
  brevieoxa 
  Banks 
  in 
  carination 
  of 
  seventh 
  tergite 
  

   (fig. 
  116 
  ; 
  lateral 
  view 
  of 
  female 
  hypopygium, 
  fig. 
  117) 
  but 
  differs 
  in 
  

   measurements 
  of 
  front 
  legs 
  as 
  indicated 
  in 
  key. 
  The 
  posterior 
  

   lateral 
  angles 
  of 
  eighth 
  tergite 
  are 
  less 
  produced 
  than 
  in 
  E. 
  brevi- 
  

   eoxa 
  and 
  much 
  less 
  than 
  in 
  average 
  specimens 
  of 
  E. 
  brevipennis
