  Paratype. 
  — 
  Female, 
  Port-of-Spain, 
  Trinidad, 
  F. 
  W. 
  Urich 
  

   (U.S.N.M.), 
  Cat. 
  No.

  The 
  latter 
  specimen 
  is 
  accompanied 
  by 
  some 
  eggs 
  (figs. 
  189. 
  190) 
  

   and 
  newly 
  emerged 
  nymphs 
  ; 
  the 
  former 
  are 
  1.75 
  mm. 
  in 
  length, 
  with 
  

   sparse 
  longitudinally 
  arranged, 
  irregular 
  granulations, 
  a 
  nipple-like 
  

   longitudinally 
  striate 
  cap, 
  which 
  is 
  surrounded 
  by 
  about 
  18 
  delicate, 
  

   tapered, 
  and 
  finely 
  pointed 
  appendages 
  of 
  the 
  main 
  egg 
  case, 
  the 
  

   apices 
  of 
  which 
  are 
  bent 
  inward 
  at 
  about 
  the 
  same 
  level 
  as 
  peak 
  of 
  

   the 
  cap 
  (fig. 
  189). 
  The 
  nymphs 
  are 
  notable 
  chiefly 
  for 
  the 
  surpris- 
  

   ingly 
  advanced 
  state 
  of 
  development 
  of 
  the 
  thorax 
  and 
  its 
  append- 
  

   ages, 
  and 
  for 
  the 
  very 
  undeveloped 
  condition 
  of 
  the 
  abdomen 
  ; 
  they 
  

   are 
  certainly 
  equipped 
  for 
  capture 
  before 
  digestion 
  of 
  prey. 
  

  

  The 
  males 
  and 
  females 
  here 
  listed 
  are 
  associated 
  as 
  one 
  species 
  not 
  

   only 
  because 
  of 
  their 
  general 
  agreement 
  in 
  color 
  and 
  form 
  but 
  specif- 
  

   ically 
  because 
  they 
  share 
  a 
  character 
  unusual 
  in 
  the 
  genus, 
  namely, 
  

   absence 
  of 
  central 
  keel 
  on 
  meta- 
  and 
  meso-sterni.
