  CAMPYLACANTHA

  new 
  species. 
  

   (Plate

  Dark 
  bluish 
  ^reen, 
  more 
  or 
  less 
  infuscated 
  and 
  enlivened 
  by 
  various 
  

   shades 
  of 
  green. 
  A 
  broad, 
  longitudinal, 
  sordid 
  yellow 
  stripe 
  beliiiid 
  the 
  

   upper 
  half 
  of 
  the 
  eyes, 
  beginning 
  at 
  their 
  nearest 
  approximation, 
  leaves 
  

   on 
  the 
  top 
  of 
  the 
  head 
  a 
  broad, 
  equal, 
  dark 
  bluish 
  green 
  dorsal 
  stripe; 
  

   the 
  genae 
  are 
  more 
  or 
  less 
  mottled 
  witli 
  olivaceous 
  and 
  the 
  antennae 
  are 
  

   ferruginous, 
  deeply 
  infuscated. 
  Pronotum 
  more 
  or 
  less 
  deeply 
  tinged 
  

   with 
  dark 
  olivaceous, 
  the 
  upper 
  half 
  of 
  the 
  lateral 
  lobes 
  of 
  the 
  prozoua 
  

   alone 
  pure 
  bluish 
  green, 
  though 
  the 
  dorsum 
  of 
  the 
  nietazona 
  approaches 
  

   it. 
  Tegmina 
  dull 
  green, 
  infuscated 
  basally, 
  nearly 
  or 
  quite 
  half 
  as 
  long 
  

   as 
  the 
  abdomen, 
  subacuminate. 
  Fore 
  and 
  middle 
  femora 
  dull 
  ferru- 
  

   ginous, 
  apically 
  dark 
  olivaceous; 
  hind 
  femora 
  stouter 
  than 
  in 
  the 
  two 
  

   preceding 
  species, 
  bluish 
  green 
  on 
  the 
  outer 
  face, 
  slightly 
  infuscated 
  at 
  

   the 
  incisures, 
  greenish 
  fuscous 
  above 
  feebly 
  bifasciate 
  with 
  fuscous, 
  

   flavo-luteous 
  below 
  and 
  within, 
  and 
  with 
  a 
  feeble 
  and 
  broken 
  testa- 
  

   ceous 
  pregenicular 
  annulus; 
  hind 
  tibiae 
  pale 
  bluish 
  green, 
  deepest 
  at 
  

   base, 
  followed 
  by 
  a 
  dull 
  luteous 
  annulus 
  and 
  becoming 
  lutesceut 
  api- 
  

   cally, 
  the 
  spines 
  tipped 
  with 
  black. 
  Bupraanal 
  plate 
  of 
  male 
  similar 
  to 
  

   that 
  of 
  the 
  two 
  preceding 
  species, 
  but 
  flatter, 
  with 
  lower 
  ridges 
  ; 
  furcula 
  

   as 
  there; 
  cerci 
  almost 
  as 
  long 
  as 
  the 
  supraanal 
  plate, 
  tapering 
  very 
  

   rapidly 
  in 
  the 
  basal 
  third, 
  beyond 
  slender, 
  less 
  than 
  half 
  as 
  broad 
  as 
  

   the 
  base, 
  subequal, 
  expanding 
  feebly 
  beyond 
  the 
  middle 
  and 
  then 
  

   tapering 
  again, 
  the 
  lower 
  portion 
  of 
  the 
  tip 
  very 
  slightly 
  produced 
  and 
  

   very 
  feebly 
  curved 
  downward 
  ; 
  infracercal 
  plates 
  much 
  as 
  in 
  the 
  preced- 
  

   ing 
  species 
  or 
  perhaps 
  broader 
  basally. 
  

  

  Length 
  of 
  body, 
  male, 
  23.5 
  mm., 
  female, 
  35 
  mm.; 
  antennae, 
  male, 
  

   female,

  mm.; 
  tegmina, 
  male, 
  9 
  mm., 
  female, 
  11.5 
  mm.; 
  hind 
  femora, 
  

   male, 
  13.5 
  mm., 
  female, 
  17.5 
  mm. 
  

  

  One 
  male, 
  1 
  female. 
  Lerdo, 
  Durango, 
  Mexico, 
  November 
  (L. 
  Briiner). 
  

  

  This 
  species, 
  though 
  closely 
  allied 
  to 
  the 
  preceding, 
  is 
  distinguish- 
  

   able 
  from 
  it 
  not 
  only 
  by 
  its 
  colors, 
  but 
  by 
  the 
  greater 
  stoutness 
  of 
  the 
  

   hind 
  femora, 
  more 
  easily 
  recognized 
  than 
  described.
