  Nymphs. 
  — 
  Several 
  nymphs 
  presumably 
  of 
  this 
  species 
  are 
  at 
  hand 
  

   from 
  Cacao, 
  Trece 
  Aguas, 
  March 
  27 
  to 
  April 
  2G. 
  There 
  is 
  a 
  rather 
  

   prominent 
  triangular 
  elevation 
  on 
  the 
  middle 
  of 
  the 
  hind 
  margin 
  of 
  

   each 
  tergite, 
  that 
  on 
  the 
  seventh 
  being 
  most 
  prominent 
  and 
  angularly 
  

   projecting; 
  the 
  lateral 
  angles 
  also 
  are 
  tuberculate 
  prominent; 
  the 
  

   eighth 
  and 
  ninth 
  tergite 
  roofing 
  the 
  anal 
  tube 
  of 
  the 
  female 
  have 
  

   only 
  suggestions 
  of 
  the 
  corrugations 
  and 
  keels 
  they 
  later 
  acquire. 
  

  

  GHILIANELLA 
  PATRUELA, 
  new 
  species. 
  

  

  Male. 
  — 
  Color 
  dark 
  reddish 
  brown, 
  pale 
  markings 
  of 
  legs 
  merely 
  

   suggested; 
  granulations 
  of 
  head 
  and 
  thorax 
  nearly 
  obsolete, 
  a 
  few 
  

   small 
  ones 
  on 
  sides 
  of 
  mesothorax; 
  abdomen 
  about 
  as 
  in 
  strigata, 
  

   lacking 
  the 
  wartlike 
  elevations, 
  however, 
  and 
  the 
  suture 
  between 
  the 
  

   fourth 
  and 
  fifth 
  tergites 
  is 
  straight 
  across, 
  instead 
  of 
  posteriorly 
  

   convex 
  as 
  in 
  that 
  form; 
  all 
  sternites 
  rounded 
  emarginate 
  medianly, 
  

   arcuate 
  laterally, 
  the 
  posterior 
  ones 
  more 
  pronouncedly 
  so; 
  hy- 
  

   popygium 
  rather 
  long, 
  the 
  posterior 
  margin 
  bisinuate 
  on 
  each 
  side, 
  

   the 
  lower 
  angle 
  conspicuous 
  but 
  by 
  no 
  means 
  so 
  much 
  so 
  as 
  in 
  strigata, 
  

   the 
  more 
  slender 
  genital 
  hook 
  arising 
  from 
  within 
  the 
  angle 
  and 
  

   directed 
  posteriorly 
  and 
  upwards, 
  the 
  apex 
  simply 
  truncate 
  ; 
  claspers 
  

   and 
  fifth 
  sternite 
  as 
  described 
  in 
  key 
  (fig.

  chiefly 
  of 
  the 
  fifth 
  segment 
  which 
  is 
  greatly 
  ex- 
  

   panded, 
  the

  tergite 
  almost 
  twice 
  

   as 
  long

  and 
  projecting 
  somewhat 
  beyond 
  

   hypopygium 
  (fig. 
  195) 
  ; 
  seventh 
  sternite 
  slightly 
  emarginate 
  at 
  the 
  

   middle 
  of 
  hind 
  margin, 
  eighth 
  half 
  as 
  long 
  as 
  the 
  seventh. 
  

  

  Female. 
  — 
  Segments 
  2-4 
  of 
  abdomen 
  less 
  slender, 
  the 
  fourth 
  not 
  

   so 
  abruptly 
  expanded, 
  about 
  half 
  of 
  sixth 
  segment 
  involved 
  in 
  the 
  

   bulbosity 
  (fig. 
  196) 
  ; 
  seventh 
  tergite 
  slightly 
  bisinuate
