  the 
  male,

  the 
  

   abdomen

  Supraannl 
  plate 
  of 
  male 
  subtriangular, 
  with 
  

   a 
  slight, 
  rounded, 
  lobiform, 
  apical 
  prolongation, 
  the 
  surface 
  nearly 
  flat, 
  

   with 
  a 
  slight, 
  rather 
  broad 
  median 
  sulcus 
  on 
  the 
  basal 
  half 
  or 
  more; 
  

   furcula 
  consisting 
  of 
  a 
  pair 
  of 
  very 
  slightly 
  projecting 
  but 
  moderately 
  

   large, 
  rounded, 
  attingent 
  lobes; 
  cerci 
  compressed 
  more 
  than 
  commonly 
  

   in 
  this 
  genus, 
  broad 
  at 
  base, 
  tapering 
  pretty 
  regularly 
  in 
  the 
  basal 
  two- 
  

   thirds, 
  mostly 
  by 
  the 
  excision 
  of 
  the

  equal, 
  apically 
  

   bluntly 
  rounded, 
  scarcely 
  incurved;

  This 
  species 
  differs 
  slightly 
  from 
  Ac. 
  unlformis 
  in 
  markings, 
  but 
  more 
  

   in 
  the 
  sculpture 
  of 
  the 
  face 
  and 
  of 
  the 
  male 
  abdominal 
  appendages, 
  

   which 
  are 
  very 
  distinct 
  in 
  the 
  basal 
  breadth 
  of 
  the 
  cerci 
  and 
  the 
  flat-

  (Plate

  Pale 
  yellowish 
  testaceous, 
  uniform, 
  the 
  only 
  variations 
  from 
  it 
  being 
  

   in 
  the 
  i)ale 
  reddish 
  antennae, 
  chocolate 
  brown 
  eyes, 
  the 
  faint, 
  fuscous, 
  

   crowded, 
  and 
  delicate 
  punctuation 
  of 
  the 
  submargiual 
  sulcus 
  of 
  the 
  

   prozona 
  and 
  of 
  the 
  whole 
  of 
  the 
  metazona, 
  the 
  bluish 
  main 
  rays 
  of 
  the 
  

   wings, 
  the 
  feeble, 
  plumbeo-fuscous, 
  sagittate 
  banding 
  of 
  the 
  hind 
  

   femora, 
  the 
  narrow 
  purplisli 
  crescent 
  of 
  the 
  genicular 
  lobes 
  and 
  the 
  

   very 
  pale 
  purplish 
  hind 
  tibiae, 
  the 
  spines 
  of 
  which 
  are 
  yellowish 
  in 
  the 
  

   basal, 
  black 
  in 
  the 
  apical 
  half. 
  The 
  eyes 
  of 
  the 
  male 
  are 
  very 
  large 
  

   and 
  prominent, 
  the 
  fastigium 
  pretty 
  deeply 
  and 
  rather 
  narrowly 
  sulcate 
  

   between 
  the 
  eyes, 
  the 
  frontal 
  costa 
  moderately 
  broad, 
  subequal, 
  nowhere 
  

   sulcate, 
  and 
  rather 
  indistinctly 
  percurrent. 
  Posterior 
  sulcus 
  of 
  the 
  

   prozona 
  swerving 
  backward 
  mesially 
  to 
  form 
  a 
  very 
  broad 
  W, 
  and 
  yet 
  

   in 
  the 
  middle 
  much 
  nearer 
  the 
  sulcus 
  in 
  front 
  than 
  that 
  behind; 
  sulcus 
  

   in 
  front 
  of 
  it 
  percurrent, 
  straight, 
  but 
  angularly 
  bent 
  forward 
  laterally. 
  

   Tegmina 
  considerably 
  longer 
  than 
  the 
  abdomen 
  in 
  the 
  male. 
  Supra- 
  

   anal 
  plate 
  of 
  male 
  triangular, 
  with 
  the 
  apex 
  slightly 
  produced 
  and 
  

   rounded, 
  nearly 
  flat, 
  with 
  a 
  rather 
  broad 
  and 
  shallow 
  median 
  sulcus, 
  

   suddenly 
  narrowed 
  and 
  almost 
  immediately 
  terujinated 
  in 
  tlie 
  middle 
  

   of 
  the 
  plate, 
  the 
  margins 
  sharply 
  delined; 
  furcula 
  consisting 
  of 
  a 
  pair 
  

   of 
  Juxtaposed, 
  small, 
  rounded 
  lobes, 
  scarcely 
  perceptible 
  by 
  any 
  projec- 
  

   tion; 
  cerci 
  broad 
  at 
  base 
  and 
  equal 
  on 
  basal 
  ftfth, 
  but 
  in 
  the 
  next 
  two 
  

   fifths 
  rapidly 
  tapering, 
  almost 
  entirely 
  by 
  the 
  falling 
  slope 
  of 
  the 
  upper 
  

   side, 
  beyond 
  subequal, 
  bluntly 
  pointed, 
  longer 
  than 
  the 
  supraanal 
  plate
