  very 
  distinct, 
  the 
  lens 
  or 
  microscope 
  shows 
  no 
  additional 
  details, 
  and 
  

   it 
  is 
  impossible 
  to 
  say 
  more 
  about 
  the 
  venation 
  than 
  that 
  it 
  appears 
  

   to 
  be 
  perfectly 
  normal 
  for 
  a 
  mantid 
  with 
  a 
  broad 
  costal 
  field, 
  such 
  

   as 
  the 
  female 
  of 
  Stagmomantis 
  limbata 
  (Halm). 
  The 
  tessellated 
  

   markings 
  resemble 
  those 
  of 
  the 
  lower 
  ^vings 
  of 
  Stagmomantis 
  and 
  

   other 
  manfcids. 
  

  

  I 
  had 
  taken 
  this 
  for 
  a 
  locustid, 
  and 
  made 
  many 
  efforts 
  to 
  find 
  some- 
  

   thing 
  similar 
  in 
  the 
  modern 
  fauna, 
  both 
  by 
  examining 
  the 
  literature 
  

   and 
  consulting 
  specialists 
  in 
  the 
  group. 
  Here 
  I 
  failed 
  entirely, 
  but 
  

   Prof. 
  L. 
  Bruner, 
  to 
  whom 
  I 
  sent 
  a 
  photograph, 
  remarked 
  that 
  the 
  

   insect 
  looked 
  to 
  him 
  more 
  like 
  a 
  mantid, 
  and 
  once 
  having 
  this 
  clue 
  

   I 
  soon 
  became 
  convinced 
  that 
  it 
  belonged 
  to 
  that 
  family.

  LffiELLULAPIS 
  WILMATTiE, 
  new 
  species. 
  

  

  Female. 
  — 
  Length 
  l.Si 
  mm., 
  anterior 
  wing 
  about 
  8 
  mm.; 
  rather 
  

   robust; 
  the 
  head 
  and 
  thorax 
  were 
  apparently 
  black, 
  the 
  abdomen 
  

   pale 
  (as 
  preserved 
  very 
  pale 
  reddish, 
  with 
  faint 
  suffused 
  bands, 
  only 
  

   that 
  on 
  the 
  fourth 
  segment 
  conspicuous, 
  the 
  apex 
  also 
  a 
  little 
  darkened) 
  ; 
  

   head 
  very 
  broad, 
  its 
  breadth 
  5 
  mm., 
  being 
  the 
  same 
  as 
  that 
  of 
  the 
  

   thorax 
  in 
  the 
  region 
  of 
  the 
  wings; 
  ocelli 
  rather 
  large; 
  legs 
  broadly 
  

   hairy; 
  abdomen 
  with 
  a 
  heavy 
  apical 
  fringe 
  of 
  hair, 
  but 
  no 
  ventral 
  

   scopa; 
  wings 
  hyalme, 
  reddish, 
  stigma 
  and 
  nervures 
  ferruginous; 
  

   pygidial 
  plate 
  broad 
  at 
  base, 
  then 
  rapidly 
  narrowing, 
  but 
  expanding 
  

   apically, 
  though 
  of 
  course 
  much 
  narrower 
  there 
  than 
  at 
  base. 
  

  

  Marginal 
  cell 
  long, 
  pointed, 
  though 
  not 
  very 
  sharply, 
  the 
  point 
  

   only 
  a 
  very 
  short 
  distance 
  from 
  costa; 
  stigma 
  rather 
  well 
  developed 
  

   (considerably 
  larger 
  than 
  in 
  LitTiurgus, 
  etc.); 
  two 
  submargmal 
  cells, 
  

   the 
  second 
  very 
  long, 
  considerably 
  longer 
  than 
  the 
  first; 
  basal 
  ner- 
  

   vure 
  straight, 
  except 
  for 
  a 
  slight 
  bend 
  at 
  its 
  lower 
  end; 
  basal 
  nervure 
  

   mectmg 
  transversomedial, 
  the 
  latter 
  strongly 
  oblique, 
  the 
  lower 
  end 
  

   more 
  apical; 
  second 
  submarginal 
  cell 
  receiving 
  both 
  recurrent 
  ner- 
  

   vures, 
  the 
  first 
  some 
  distance 
  from 
  the 
  base, 
  the 
  other 
  about 
  one- 
  

   fourth 
  of 
  this 
  distance 
  from 
  the 
  apex; 
  second 
  recurrent 
  nervure 
  with 
  

   a 
  gentle 
  curve. 
  

  

  Hind 
  wing 
  with 
  the 
  venation 
  ordinary, 
  except 
  that 
  the 
  distance 
  

   from 
  the 
  upper 
  end 
  of 
  the 
  transversomedial 
  nervure 
  to 
  the 
  beginning 
  

   of 
  the 
  discoidal 
  cell 
  is 
  much 
  less 
  than 
  the 
  side 
  of 
  the 
  discoidal 
  cell 
  on 
  

   the 
  median 
  cell. 
  (This 
  peculiarity 
  is 
  also 
  observed, 
  though 
  less 
  pro- 
  

   nounced, 
  in 
  Panurgus, 
  especially 
  P. 
  calcaratus; 
  the 
  second 
  submar- 
  

   ginal 
  cell 
  is 
  also 
  very 
  long 
  in 
  Panurgus.)
