  nearly 
  straight 
  across; 
  process 
  of 
  sixth 
  tergite 
  long, 
  but 
  not 
  quite 
  

   reaching 
  apex 
  of 
  hypopygium, 
  almost 
  parallel-sided 
  for 
  most 
  of 
  its 
  

   length, 
  a 
  little 
  constricted 
  beyond 
  middle, 
  transversely 
  wrinkled 
  

   basally, 
  rather 
  abruptly 
  narrowed, 
  bluntly-pointed 
  and 
  punctate 
  

   apically. 
  

  

  Length, 
  30-32 
  mm.

  The

  specimen 
  dif- 
  

   fers 
  in 
  having 
  hind 
  margin 
  of 
  sixth 
  sternite 
  convex 
  instead 
  of 
  

   slightly

  Bolivia, 
  J. 
  Stein- 
  

   bach 
  (Carnegie 
  Mus., 
  Ace. 
  No.

  probably 
  is 
  this 
  species; 
  as 
  

   usual 
  with 
  nymphs 
  of 
  the 
  genus 
  it 
  is 
  more 
  profusely 
  and 
  boldly 
  

   marked 
  than 
  the 
  adults. 
  

  

  IloJotype. 
  — 
  The 
  first 
  specimen 
  listed. 
  

  

  An 
  adult 
  female, 
  for 
  geographical 
  reasons 
  regarded 
  as 
  belonging 
  

   to 
  this 
  species, 
  bears 
  the 
  following 
  data 
  : 
  French 
  Guiana, 
  R. 
  Oberthur, 
  

   1899 
  (Paris 
  Mus.). 
  It 
  differs 
  in 
  coloration 
  from 
  the 
  male 
  only 
  in 
  

   being 
  a 
  little 
  duller, 
  the 
  markings 
  especially 
  of 
  the 
  front 
  legs 
  being 
  

   less 
  contrasted. 
  The 
  seventh 
  tergite 
  is 
  very 
  broad 
  apically, 
  the 
  whole 
  

   margin 
  of 
  the 
  disk 
  a 
  little 
  swollen; 
  eighth 
  tergite 
  strongly 
  carinate 
  

   along 
  the 
  nearly 
  parallel 
  sides 
  of 
  disk, 
  the 
  carinae 
  thickest 
  at 
  base, 
  

   each 
  with 
  deep 
  impression 
  basally, 
  apex 
  of 
  tergite 
  rounded 
  subangu- 
  

   late 
  medianly 
  (figs. 
  131a, 
  132). 
  

  

  Emesaya 
  precatoria 
  (Emesa 
  precatovius 
  Fabricius, 
  J. 
  C. 
  13 
  [Middle 
  

   America] 
  ) 
  , 
  seems 
  to 
  be 
  much 
  like 
  E. 
  apiculata. 
  We 
  have 
  been 
  sup- 
  

   plied, 
  through 
  the 
  kindness 
  of 
  Dr. 
  William 
  Lundbeck, 
  with 
  sketches 
  

   and 
  notes 
  relating 
  to 
  the 
  type 
  specimen, 
  which 
  differs 
  chiefly 
  from 
  

   the 
  species 
  here 
  described 
  in 
  the 
  emargination 
  of 
  the 
  male 
  clasper 
  

   (fig. 
  1315) 
  and 
  shape 
  of 
  the 
  apical 
  hypopygial 
  process 
  (fig. 
  131c). 
  

  

  EMESAYA 
  POLLEX, 
  new 
  species. 
  

  

  Male. 
  — 
  Chiefly 
  castaneous, 
  the 
  legs 
  and 
  antennae 
  paler; 
  the 
  tylus, 
  

   middle 
  of 
  head 
  just 
  behind 
  it, 
  areas 
  inside 
  eyes 
  and 
  posterior 
  lobe 
  of 
  

   thorax 
  tending 
  to 
  be 
  paler. 
  Darkening 
  of 
  the 
  disk 
  of 
  latter 
  in 
  some 
  

   specimens 
  gives 
  the 
  effect 
  of 
  pale 
  marginal 
  stripes. 
  The 
  connexivum 
  

   is 
  touched 
  with 
  luteous. 
  Front 
  tibia 
  and 
  femur 
  with 
  pale 
  areas 
  but 
  

   scarcely 
  banded; 
  mid 
  and 
  hind 
  femora 
  with 
  evident 
  terminal 
  and 
  

   faint 
  subterminal, 
  tibiae 
  with 
  basal 
  and 
  subbasal, 
  pale 
  annuli. 
  Tip 
  

   of 
  first 
  antennal 
  segment 
  pale. 
  Wings 
  hyaline, 
  a 
  little 
  denser 
  at 
  

   base.
