  the 
  hind 
  margin 
  of 
  the 
  pronotum 
  plainly 
  reflexed 
  and 
  strongly 
  

   undulate 
  throughout. 
  The 
  hind 
  tibiae 
  are 
  spined 
  at 
  the 
  apex 
  exter- 
  

   nally 
  and 
  the 
  prosternum 
  has 
  its 
  anterior 
  margin 
  developed 
  into 
  a 
  

   fairly 
  strong 
  spine. 
  

  

  While 
  very 
  distinct 
  from 
  all 
  other 
  known 
  forms 
  this 
  insect 
  seems 
  

   to 
  show 
  affinities 
  with 
  the 
  Ommexichidse 
  rather 
  than 
  with 
  the 
  

   Acridiidse 
  or 
  Cjnrtacanthacridse, 
  as 
  we 
  may 
  be 
  obliged 
  to 
  write 
  it. 
  

   Its 
  type 
  is 
  the 
  following-described 
  species: 
  

  

  CUMAINOCLOIDUS 
  CORDILLERA, 
  new 
  species. 
  

  

  Body 
  robust 
  about 
  the 
  thorax 
  and 
  the 
  base 
  of 
  the 
  abdomen, 
  com- 
  

   pressed, 
  the 
  surface 
  of 
  the 
  head, 
  pronotum, 
  meso- 
  and 
  meta-thorax 
  

   and 
  the 
  basal 
  segment 
  of 
  the 
  abdomen 
  irregularly 
  and 
  strongly 
  

   rugose. 
  Head 
  moderately 
  large, 
  higher 
  than 
  wide, 
  its 
  sides 
  nearly 
  

   parallel, 
  set 
  into 
  the 
  thorax 
  almost 
  to 
  the 
  eyes. 
  Latter 
  small, 
  not 
  

   prominent, 
  elhptical, 
  separated 
  above 
  by 
  a 
  space 
  equal 
  to 
  their 
  

   shortest 
  diameter, 
  the 
  front 
  portion 
  of 
  the 
  occiput 
  irregularly 
  rugose, 
  

   the 
  vertex 
  but 
  little 
  depressed, 
  bounded 
  by 
  strong 
  but 
  sinuose 
  

   carinse 
  that 
  converge 
  suddenly 
  in 
  front 
  and 
  unite 
  with 
  the 
  lateral 
  

   walls 
  of 
  the 
  frontal 
  costa, 
  the 
  sulcation 
  irregularly 
  studded 
  %\dth 
  

   rugosities; 
  frontal 
  costa 
  moderately 
  prominent, 
  narrow 
  above, 
  

   evenly 
  and 
  gently 
  expanding 
  below, 
  continuous 
  to 
  the 
  clypeus, 
  pro- 
  

   foundly 
  sulcate 
  and 
  also 
  studded 
  below 
  the 
  ocellus 
  with 
  a 
  few 
  rugosi- 
  

   ties; 
  lateral 
  or 
  facial 
  carinae 
  somewhat 
  divergent 
  below, 
  somewhat 
  

   irregular 
  or 
  crenulate; 
  the 
  front 
  rather 
  profusely 
  rugulose, 
  as 
  are 
  also 
  

   the 
  gense, 
  the 
  anterior 
  margin 
  of 
  the 
  latter 
  nearly 
  or 
  quite 
  one-half 
  

   longer 
  than 
  the 
  eyes. 
  AntennsB 
  slender, 
  not 
  quite 
  as 
  long 
  as 
  the 
  head 
  

   and 
  pronotum 
  combined, 
  most 
  of 
  the 
  joints 
  a 
  little 
  depressed, 
  16 
  or 
  

   17 
  in 
  number. 
  Pronotum 
  tectiform, 
  the 
  median 
  carina 
  prominent 
  

   and 
  notched 
  by 
  all 
  three 
  transverse 
  sulci, 
  giving 
  to 
  it 
  a 
  lobed 
  appear- 
  

   ance 
  when 
  viewed 
  laterally, 
  the 
  posterior 
  sulcus 
  alone 
  continuous; 
  

   lateral 
  carinas 
  wanting; 
  anterior 
  margin 
  faintly 
  undulate 
  and 
  slightly 
  

   angulately 
  advanced 
  upon 
  the 
  occiput, 
  but 
  with 
  the 
  apex 
  gently 
  

   notched; 
  hind 
  margin 
  somewhat 
  thickened 
  or 
  reflexed, 
  lobately 
  

   undulate 
  throughout 
  with 
  about 
  seven 
  such 
  lobes 
  on 
  each 
  side 
  of 
  the 
  

   middle. 
  Surface 
  rugose. 
  Tegmina 
  visible 
  only 
  as 
  very 
  minute 
  

   lateral 
  pads, 
  the 
  apex 
  of 
  which 
  barely 
  show 
  beyond 
  the 
  hind 
  margin 
  

   of 
  the 
  pronotum. 
  Hind 
  femora 
  moderately 
  robust, 
  evenly 
  tapering 
  

   toward 
  the 
  apex, 
  the 
  outer 
  and 
  upper 
  carinas 
  rather 
  distantly 
  and 
  

   minutely 
  spined 
  or 
  toothed; 
  hind 
  tibiae 
  robust, 
  11-spined 
  on 
  both 
  

   margins 
  including 
  the 
  apical 
  ones, 
  the 
  spines 
  heavy 
  and 
  equal 
  on 
  the 
  

   two 
  margins, 
  extending 
  from^near 
  the 
  base. 
  Prosternum 
  with 
  its 
  

   anterior 
  margin 
  at 
  center 
  raised 
  so 
  as 
  to 
  form 
  a 
  fairly 
  acute 
  triangular 
  

   spine. 
  Mesosternal 
  lobes 
  rounded 
  internally, 
  the 
  space 
  between 
  them 
  

   fully 
  twice 
  as 
  wide 
  as 
  long 
  and 
  wider 
  than 
  the 
  lobes 
  themselves;
