  witli 
  no 
  obtuse 
  apically 
  emarginate 
  lobe 
  [fureula], 
  the 
  hind 
  femora 
  

   slenderer 
  and 
  longer, 
  prosterual 
  spine 
  coni(;al, 
  and 
  the 
  antennae 
  longer, 
  

   more 
  than 
  half 
  as 
  long 
  as 
  the 
  body; 
  hind 
  tibiae 
  in 
  the 
  specimen 
  

   described 
  furnished 
  exteriorly 
  with 
  eight 
  black 
  spines, 
  greenish 
  oliva- 
  

   ceous 
  at 
  the 
  base. 
  

  

  A 
  female 
  specimen, 
  in 
  which 
  the 
  dorsum 
  of 
  the 
  body 
  and 
  of 
  the 
  hind 
  

   femora 
  are 
  ferruginous, 
  with 
  smaller 
  eyes, 
  the 
  interspace 
  between 
  the 
  

   mesosternal 
  lobes 
  subtransverse 
  and 
  scarcely 
  narrower 
  than 
  the 
  lobes 
  

   themselves, 
  and 
  metasternal 
  lobes 
  moderately 
  distant, 
  is 
  very 
  probably 
  

   to 
  be 
  referred 
  to 
  the 
  species 
  described 
  above. 
  In 
  this 
  specimen 
  the 
  

   antennae 
  are 
  mutilated 
  and 
  the 
  hind 
  tibiae 
  armed 
  exteriorly 
  with 
  nine 
  

   spines.

  collection). 
  

  

  To 
  this 
  I 
  may 
  add 
  that 
  the 
  present 
  species 
  is 
  certainly 
  very 
  close 
  to 
  

   the 
  others 
  described 
  above 
  under 
  this 
  genus, 
  but 
  seems 
  to 
  be 
  slightly 
  

   larger 
  than 
  either, 
  and 
  to 
  differ 
  by 
  the 
  cerci 
  of 
  the 
  male 
  to 
  a 
  greater 
  

   degree 
  than 
  either 
  of 
  these 
  do 
  from 
  each 
  other. 
  It 
  is 
  evidently 
  also 
  of 
  

   a 
  lighter 
  color, 
  and 
  no 
  mention 
  is 
  made 
  by 
  Stal 
  of 
  a 
  very 
  distinct 
  dark 
  

   lateral 
  band, 
  which 
  is 
  characteristic 
  of 
  the 
  other 
  two.

  CYCLOCERCUS, 
  new 
  genus. 
  

   {hvkXo't, 
  circle; 
  xepjio'-, 
  tail.) 
  

  

  Body 
  shaped 
  much 
  as 
  in 
  Paraidemona, 
  male 
  and 
  female, 
  rather 
  

   sparsely 
  and 
  not 
  very 
  briefly 
  pilo.^e. 
  Head 
  not 
  prominent, 
  the 
  vertex 
  

   moderately 
  arched, 
  scarcely 
  elevated 
  above 
  the 
  pronotum, 
  but 
  the 
  

   fastigium 
  rapidly 
  descending, 
  more 
  or 
  less 
  sulcate 
  especially 
  in 
  the 
  

   male, 
  much 
  broadened 
  anteriorly; 
  face 
  moderately 
  retreating, 
  the 
  

   frontal 
  costa 
  generally 
  more 
  or 
  less 
  sulcate 
  and 
  broadening 
  slightly 
  

   from 
  above 
  downward, 
  generally 
  percurrent; 
  interval 
  between 
  the 
  eyes 
  

   narrow 
  (male) 
  or 
  rather 
  narrow 
  (female), 
  generally 
  narrower 
  than 
  the 
  

   upper 
  part 
  of 
  the 
  frontal 
  costa; 
  eyes 
  moderately 
  prominent, 
  especially 
  

   in 
  the 
  male, 
  generally 
  much 
  (male) 
  or 
  scarcely 
  (female) 
  longer 
  than 
  the 
  

   posterior 
  infraocular 
  portion 
  of 
  the 
  genae; 
  antennae 
  much 
  (male) 
  or 
  

   scarcely 
  if 
  at 
  all 
  (female) 
  longer 
  than 
  the 
  head 
  and 
  pronotum 
  together. 
  

   Pronotum 
  scarcely 
  (male) 
  or 
  considerably 
  (female) 
  enlarging 
  from 
  in 
  

   front 
  backward, 
  both 
  front 
  and 
  hind 
  margins 
  truncate, 
  the 
  latter 
  some- 
  

   times 
  slightly 
  emarginate, 
  the 
  surface 
  transversely 
  convex 
  with 
  feeble 
  

   or 
  no 
  median 
  carina 
  and 
  no 
  lateral 
  carinae, 
  the 
  disk 
  passing 
  almost 
  

   insensibly 
  into 
  the 
  vertical 
  lateral 
  lobes; 
  prozoua 
  about 
  twice 
  as 
  long- 
  

   as 
  the 
  metazona 
  and 
  less 
  closely 
  and 
  less 
  regularly 
  punctate, 
  the 
  trans- 
  

   verse 
  sulci 
  as 
  in 
  Siualoa. 
  Prosterual 
  spine 
  erect, 
  blunt, 
  conical; 
  inter- 
  

   val 
  between 
  mesosternal 
  lobes 
  at 
  least 
  as 
  long 
  as 
  broad 
  in 
  the 
  male, 
  a 
  

   little 
  transverse 
  in 
  the 
  female, 
  the 
  metasternal 
  lobes 
  attingent 
  or 
  sub- 
  

   attingent 
  in 
  the 
  male, 
  approximate 
  in 
  the 
  female. 
  Tegmina 
  shorter 
  

   than 
  the 
  pronotum, 
  lateral, 
  linear. 
  Fore 
  and 
  middle 
  femora 
  distinctly 
  

   more 
  gibbous 
  in 
  the 
  male 
  than 
  in 
  the 
  female; 
  hind 
  femora 
  rather 
  short
