  the

  EMPICORIS 
  NUDUS, 
  new 
  species. 
  

  

  Female. 
  — 
  Head 
  marked 
  as 
  in 
  armatus; 
  the 
  white 
  lines 
  are 
  not 
  

   composed 
  of 
  moderately 
  long 
  decumbent 
  hairs 
  but 
  of 
  microscopic 
  

   pile 
  or 
  pruineseence, 
  and 
  the 
  two 
  lines 
  on 
  dorsum 
  are 
  regularly 
  

   arcuate, 
  the 
  anterior 
  and 
  posterior 
  extremities 
  being 
  incurved. 
  The 
  

   dorsum 
  of 
  pronotum 
  is 
  chocolate 
  brown 
  on 
  disk 
  between 
  the 
  white 
  

   lines, 
  the 
  latter 
  are 
  very 
  slender, 
  converge 
  from 
  anterior 
  margin 
  to 
  

   constriction, 
  and 
  then 
  arcuately 
  diverge, 
  ending 
  a 
  short 
  distance 
  from 
  

   hind 
  margin 
  of 
  pronotum; 
  laterad 
  of 
  the 
  white 
  lines 
  the 
  posterior 
  

   half 
  of 
  pronotum 
  is 
  paler 
  brown; 
  there 
  is 
  a 
  slender 
  white 
  Y-shaped 
  

   mark 
  extending 
  from 
  constriction 
  over 
  humerus 
  on 
  each 
  side, 
  a 
  

   white 
  line 
  along 
  the 
  hind 
  margin, 
  and 
  the 
  lateral 
  carinae 
  are 
  white. 
  

   In 
  other 
  respects 
  as 
  annatus. 
  

  

  Pronotum 
  almost 
  nude, 
  processes 
  and 
  spines 
  as 
  in 
  armatus. 
  Fore 
  

   coxa 
  stouter 
  than 
  in 
  that 
  species, 
  distinctly 
  shorter 
  than 
  pronotum, 
  

   and 
  half 
  as 
  long 
  as 
  femur; 
  stigmatal 
  spot 
  farther 
  from 
  apex.
