  The 
  broader 
  cerci, 
  incurved 
  throughout 
  and 
  not 
  abrujitly 
  bent

  this 
  species

  In 
  one 
  view 
  

   their 
  base 
  may 
  be 
  said 
  to 
  be 
  narrower 
  than 
  the 
  apical 
  portion 
  and 
  so 
  

   the 
  description 
  of 
  Stal's 
  species 
  would 
  be 
  applicable 
  to 
  this, 
  but 
  the 
  

   interval 
  between 
  the 
  mesosternal 
  lobes 
  of 
  the 
  male 
  is 
  here 
  nearly 
  twice 
  

   as 
  long 
  as 
  broad, 
  while 
  in 
  E. 
  pilosus 
  it 
  is 
  more 
  nearly 
  quadrate.

  Body 
  thinly 
  but 
  not 
  briefl}' 
  pilose, 
  luteo-testaceous 
  beneath, 
  black 
  or 
  

   blackish 
  ferruginous 
  (male) 
  or 
  ferrugineo 
  testaceous 
  (female) 
  above, 
  

   marked 
  with 
  dull 
  luteous; 
  the 
  darker 
  parts 
  are 
  found 
  in 
  a 
  dorsal 
  stripe 
  

   from 
  the 
  front 
  of 
  the 
  vertex 
  to 
  the 
  front 
  of 
  the 
  metazona, 
  on 
  the 
  ujtper 
  

   half 
  of 
  the 
  lateral 
  lobes 
  of 
  the 
  pronotum, 
  and 
  on 
  the 
  sides 
  of 
  the 
  

   abdomen. 
  Head 
  luteo-testaceous, 
  more 
  or 
  less 
  deeply 
  infuscated: 
  

   frontal 
  costa 
  feebly 
  punctate 
  above,* 
  antennae 
  luteous 
  or 
  testaceous, 
  

   apically 
  infuscated. 
  Pronotum 
  with 
  the 
  dark 
  jfortions 
  mentioned 
  

   separated 
  by 
  a 
  narrow 
  light 
  stripe, 
  which 
  begins 
  behind 
  the 
  upper 
  

   part 
  of 
  the 
  eyes 
  and 
  on 
  the 
  head 
  is 
  bright 
  luteous, 
  but 
  in 
  passing 
  over 
  

   the 
  i)ronotum, 
  especially 
  in 
  the 
  female, 
  becomes 
  much 
  duller 
  and 
  is 
  

   sometimes 
  scarcely 
  distinguishable; 
  in 
  most 
  vivid 
  examples 
  it 
  crosses 
  

   the 
  i^ronotum, 
  but 
  even 
  in 
  the 
  male 
  it 
  usually 
  becomes 
  obsolescent 
  on 
  

   the 
  metazona, 
  which 
  is 
  mostly 
  ferrugineo-testaceous 
  in 
  both 
  sexes, 
  

   rarely 
  black 
  mesially 
  in 
  the 
  male; 
  the 
  lateral 
  stripe 
  on 
  the 
  pronotum 
  

   generally 
  margined 
  more 
  or 
  less 
  distinctly 
  with 
  black 
  ; 
  lower 
  portions 
  

   of 
  lateral 
  lobes 
  luteous 
  or 
  luteo-testaceous, 
  narrowly 
  edged 
  beneath 
  

   with 
  testaceous; 
  abdomen 
  with 
  a 
  widening 
  dorsal 
  stripe 
  of 
  ferrugineo 
  

   testaceous. 
  Fore 
  and 
  middle 
  femora 
  ferruginous, 
  slightly 
  infuscated 
  

   apically; 
  hind 
  femora 
  green, 
  ferruginous 
  above, 
  the 
  upper 
  genicular 
  

   lobe 
  and 
  sometimes 
  the 
  whole 
  geniculation 
  black; 
  hind 
  tibiae 
  green, 
  

   the 
  spines 
  black-tipped, 
  usually 
  nine 
  but 
  varying 
  from 
  nine 
  to 
  eleveu 
  

   in 
  the 
  outer 
  series. 
  Supraanal 
  plate 
  of 
  male 
  triangular 
  with 
  slightly 
  

   convex 
  sides, 
  which 
  are 
  slightly 
  elevated 
  and 
  separated 
  by 
  a 
  broad 
  

   valley 
  from 
  the 
  median 
  tectate 
  portion; 
  the 
  latter 
  is 
  considerably 
  ele 
  

   vated 
  and 
  carries 
  a 
  deep 
  slender 
  median 
  sulcus 
  more 
  than 
  half 
  the 
  

   length 
  of 
  the 
  plate; 
  furcula 
  consisting 
  of 
  a 
  pair 
  of 
  broad 
  plates, 
  whose 
  

   advance 
  bej^ond 
  the 
  i)osterior 
  line 
  of 
  the 
  last 
  dorsal 
  segment 
  is 
  scarcely 
  

   perceptible, 
  each 
  about 
  a 
  quarter 
  the 
  basal 
  width 
  of 
  the 
  supraanal 
  

   plate; 
  cerci 
  moderately 
  broad, 
  compressed, 
  straight 
  and 
  slightly' 
  dimin- 
  

   ishing 
  in 
  size 
  for 
  al»out 
  two-thirds 
  their 
  length, 
  then 
  suddenly 
  and 
  con 
  

   siderably 
  curved 
  inward 
  and 
  bent 
  upward, 
  narrowing 
  more 
  rapidly 
  and
