  female 
  about 
  four-fifths, 
  in 
  the 
  male 
  scarcely 
  more 
  than 
  one-half, 
  the 
  

   length 
  of 
  the 
  greater 
  diameter 
  of 
  the 
  eyes. 
  Antennae 
  short, 
  com- 
  

   paratively 
  heavy, 
  their 
  joints 
  somewhat 
  depressed 
  so 
  as 
  to 
  give 
  to 
  these 
  

   members 
  a 
  flattened 
  appearance. 
  Pronotum 
  evenly 
  widening 
  pos- 
  

   teriorly, 
  its 
  surface 
  only 
  gently 
  longitudinally 
  rugose 
  and 
  sparsely 
  

   punctured 
  on 
  the 
  hind 
  lobe; 
  the 
  median 
  carina 
  visible 
  throughout 
  but 
  

   most 
  prominent 
  on 
  the 
  posterior 
  lobe 
  and 
  near 
  the 
  front 
  edge 
  of 
  the 
  

   anterior 
  lobe; 
  lateral 
  carina? 
  present 
  on 
  the 
  hind 
  lobe 
  of 
  both 
  sexes 
  and 
  

   to 
  a 
  limited 
  extent 
  also 
  on 
  the 
  anterior 
  one; 
  front 
  margin 
  straight, 
  the 
  

   hmd 
  margin 
  truncate 
  with 
  the 
  middle 
  gently 
  emarginate. 
  Tegmina 
  

   lateral, 
  nearly 
  twice 
  (female) 
  or 
  a 
  trifle 
  more 
  than 
  twice 
  as 
  long 
  as 
  

   broad 
  (male), 
  their 
  apex 
  somewhat 
  acuminate, 
  their 
  upper 
  edges 
  dis- 
  

   tant, 
  but 
  little 
  if 
  any 
  surpassing 
  the 
  hind 
  margin 
  of 
  the 
  first 
  abdominal 
  

   segment. 
  Abdomen 
  evenly 
  tapering 
  caudal 
  in 
  the 
  female, 
  gently 
  

   clavate 
  in 
  the 
  male, 
  the 
  dorsum 
  prominently 
  carinated; 
  last 
  ventral 
  

   segment 
  of 
  male 
  elongate, 
  its 
  apex 
  scarcely 
  notched; 
  supra-anal 
  

   plate 
  roundly 
  triangulate 
  with 
  raised 
  lateral 
  margins 
  and 
  a 
  heavy 
  

   raised 
  longitudinal 
  ridge 
  extending 
  from 
  the 
  base 
  to 
  its 
  apex 
  and 
  

   narrowly 
  sulcate 
  throughout, 
  midway 
  between 
  the 
  base 
  and 
  middle 
  

   on 
  each 
  side 
  of 
  the 
  plate 
  is 
  an 
  inwardly 
  directed 
  short 
  spur 
  or 
  tooth 
  

   of 
  the 
  lateral 
  carina; 
  cerci 
  heavy 
  at 
  base 
  but 
  rapidly 
  narrowing 
  

   toward 
  the 
  middle, 
  curved 
  gently 
  upward 
  and 
  strongly 
  inward, 
  so 
  

   that 
  their 
  apices 
  almost 
  meet 
  just 
  beyond 
  the 
  apex 
  of 
  the 
  supra-anal 
  

   plate; 
  marginal 
  apophyses 
  of 
  the 
  preceding 
  segment 
  small 
  and 
  slender, 
  

   projecting 
  into 
  the 
  basal 
  portion 
  of 
  the 
  plate's 
  median 
  sulcus. 
  Valves 
  

   of 
  the 
  ovipositor 
  well 
  developed, 
  strong, 
  the 
  apices 
  gently 
  curved. 
  

   Prosternal 
  spine 
  coarse, 
  pyramidal, 
  transverse 
  at 
  base, 
  the 
  apex 
  

   blunt. 
  Hmd 
  femora 
  normal, 
  in 
  the 
  males 
  a 
  little 
  surpassing, 
  in 
  the 
  

   females 
  not 
  quite 
  reaching 
  the 
  apex 
  of 
  the 
  abdomen. 
  Hind 
  tibiae 
  

   9-spined 
  externally; 
  anterior 
  and 
  middle 
  femora 
  gently 
  arcuate, 
  a 
  

   little 
  (female) 
  or 
  decidedly 
  (male) 
  enlarged 
  or 
  inflated. 
  Interspace 
  

   between 
  the 
  mesosternal 
  lobes 
  as 
  wide 
  as 
  long 
  (male) 
  or 
  noticeably 
  

   wider 
  than 
  long 
  (female). 
  

  

  General 
  color 
  varying 
  from 
  dark 
  apple-green 
  to 
  a 
  pale 
  brownish- 
  

   olive, 
  more 
  or 
  less 
  varied 
  with 
  ferruginous 
  and 
  fuscous. 
  In 
  the 
  

   darker 
  specimens 
  there 
  is 
  a 
  well-defined 
  post-ocular 
  band 
  that 
  is 
  

   continued 
  across 
  the 
  upper 
  half 
  of 
  the 
  sides 
  of 
  the 
  pronotum, 
  also 
  a 
  

   ferruginous 
  triangle 
  that 
  continues 
  backward 
  across 
  the 
  disk 
  of 
  the 
  

   pronotum 
  bordered 
  laterally 
  by 
  a 
  pallid 
  line 
  above 
  the 
  carinae. 
  The 
  

   tegmina 
  of 
  all 
  color 
  phases 
  are 
  ferruginous 
  to 
  dull 
  brown; 
  the 
  dorsal 
  

   carina 
  of 
  the 
  abdomen 
  is 
  pallid, 
  with 
  an 
  approximate 
  fuscous 
  dot 
  on 
  

   either 
  side 
  near 
  the 
  middle 
  of 
  the 
  segments; 
  the 
  latter 
  are 
  largely 
  

   piceous 
  laterally, 
  and 
  especially 
  so 
  on 
  those 
  nearest 
  the 
  base. 
  Below 
  

   the 
  insect 
  varies 
  from 
  bright 
  yellow 
  to 
  pale 
  testaceous; 
  the 
  hind 
  

   femora 
  are 
  obliquely 
  banded 
  with 
  pallid 
  and 
  fuscous 
  externally, 
  while
