  (male) 
  or 
  rather 
  broader 
  tlian 
  

   (female) 
  the 
  tirst 
  anteuual 
  joint; 
  frontal 
  costa 
  moderate, 
  equal, 
  Hat 
  

   above, 
  sulcate 
  at, 
  below, 
  and 
  to 
  some 
  extent 
  a 
  short 
  distance 
  above, 
  

   the 
  ocellus. 
  Pronotuui 
  expanding 
  a 
  very 
  little 
  posteriorly, 
  mostly 
  on 
  

   the 
  posterior 
  half, 
  the 
  front 
  and 
  hind 
  margins 
  truncate, 
  the 
  latter 
  some- 
  

   times 
  almost 
  imperceptibly 
  emarginate 
  in 
  the 
  middle, 
  especially 
  in 
  the 
  

   male, 
  the 
  lateral 
  carinae 
  wholly 
  wanting; 
  the 
  whole 
  pronotum 
  is 
  equally 
  

   subrugoso-punctate 
  throughout, 
  unless 
  it 
  be 
  that 
  the 
  disk 
  is 
  coarser 
  

   than 
  the 
  deflected 
  lobes; 
  nieso- 
  and 
  metanota, 
  and 
  the 
  basal 
  segments 
  

   of 
  the 
  abdomen 
  similarly 
  but 
  more 
  obscurely 
  punctured. 
  The 
  general 
  

   color 
  is 
  a 
  greenish 
  yellow 
  more 
  or 
  less 
  tinged 
  with 
  brown, 
  brighter 
  in 
  the 
  

   male 
  than 
  in 
  the 
  female, 
  and 
  marked 
  with 
  blackish 
  fuscous; 
  the 
  darker 
  

   markings 
  consist, 
  i)rincipally, 
  of 
  a 
  dorsal 
  stripe, 
  which 
  either 
  extends 
  

   over 
  the 
  pronotum 
  as 
  a 
  broad 
  equal 
  band, 
  often 
  fainter 
  in 
  the 
  middle, 
  

   with 
  a 
  triangular 
  extension 
  on 
  the 
  head, 
  and 
  sometimes 
  a 
  narrowing 
  

   iufuscatiou 
  ou 
  the 
  meso- 
  and 
  metanota 
  (male), 
  or 
  forms 
  an 
  obovate 
  

   patch 
  along 
  the 
  middle 
  of 
  the 
  anterior 
  lobe 
  of 
  the 
  prothorax, 
  with 
  the 
  

   same 
  triangular 
  extension 
  ou 
  the 
  head, 
  and 
  reappears 
  sometimes 
  on 
  the 
  

   meso 
  and 
  metathorax, 
  and 
  always 
  on 
  the 
  abdominal 
  joints, 
  as 
  a 
  series 
  

   of 
  obliquely-descending, 
  triangular, 
  lateral 
  patches, 
  separated 
  from 
  one 
  

   another 
  by 
  a 
  yellowish 
  median 
  line 
  (female) 
  ; 
  also 
  of 
  a 
  broad 
  lateral 
  band, 
  

   which 
  extends 
  from 
  behind 
  the 
  eye 
  backward, 
  either 
  to 
  the 
  hinder 
  edge 
  

   of 
  the 
  prothorax, 
  its 
  upper 
  margin 
  straight, 
  its 
  lower 
  arcuate 
  (male), 
  or 
  

   across 
  the 
  prozona 
  only, 
  occasionally 
  in 
  an 
  obscure 
  manner 
  across 
  the 
  

   metazona 
  also, 
  both 
  margins 
  arcuate 
  (female); 
  beyond 
  this 
  the 
  lateral 
  

   band 
  extends 
  over 
  the 
  remainder 
  of 
  the 
  thorax 
  and 
  over 
  the 
  abdomen, 
  

   often 
  broken 
  into 
  spots 
  on 
  the 
  latter, 
  and 
  always 
  enlivened 
  ou 
  the 
  for- 
  

   mer 
  by 
  an 
  oblique 
  yellowish 
  line, 
  which 
  crosses 
  it 
  on 
  the 
  metathoracic 
  

   episterua. 
  The 
  face 
  partakes 
  of 
  the 
  color 
  of 
  the 
  under 
  surface, 
  as 
  do 
  the 
  

   bases 
  of 
  the 
  antennae; 
  beyond, 
  the 
  antennae 
  become 
  slightly 
  rufous; 
  

   just 
  behind 
  its 
  narrowest 
  point 
  the 
  vertex 
  has 
  a 
  transverse 
  blackish 
  

   line. 
  Hind 
  femora 
  greenish 
  yellow, 
  the 
  lower 
  portion 
  of 
  their 
  outer 
  

   face 
  more 
  or 
  less 
  embrowned, 
  deepening 
  freijuently 
  into 
  black, 
  which 
  

   occasionally 
  covers 
  the 
  whole; 
  hind 
  tibiae 
  pale 
  green, 
  the 
  spines 
  black 
  

   tipped. 
  Subgenital

  twice 
  as

  as

  tumid, 
  the 
  

   upper

  a 
  little 
  and 
  angularly
