  mm,; 
  length 
  of 
  the 
  wing 
  13, 
  of 
  the 
  body 
  11 
  mm.) 
  ; 
  the 
  

   primaries 
  are 
  in 
  the 
  dorsal 
  half 
  of 
  the 
  basal 
  area 
  partly 
  lead- 
  

   coloured 
  ; 
  the 
  face 
  and 
  vertex 
  of 
  one 
  of 
  my 
  specimens 
  greyish, 
  

   of 
  the 
  other 
  dark-coloured 
  (perhaps 
  the 
  former 
  is 
  the 
  natural 
  

   colour, 
  as 
  the 
  latter 
  specimen 
  appears 
  to 
  be 
  somewhat 
  greasy). 
  

   Most 
  probably 
  the 
  described 
  cocoon 
  from 
  Merida 
  belongs 
  

   to 
  this 
  species.

   which 
  our

  Fonteboa, 
  Upper 
  Amazonas 
  {Hahnel 
  leg.). 
  

   Cocoon, 
  vide

  From 
  Tr. 
  sanctipaulensis 
  m. 
  this 
  species 
  differs 
  by 
  a 
  dis- 
  

   tinct, 
  dirty 
  greyish-white, 
  transverse 
  (a 
  little 
  obliquely 
  

   directed) 
  band 
  at 
  the 
  end 
  of 
  the 
  basal 
  third 
  of 
  the 
  primaries 
  ; 
  

   this 
  band 
  is 
  1*8 
  mm. 
  broad 
  and 
  about 
  1 
  mm. 
  distant 
  from 
  

   both 
  the 
  costal 
  and 
  the 
  dorsal 
  edge, 
  almost 
  straight 
  and 
  

   parallel-sided 
  and 
  about 
  2*5 
  mm, 
  (in 
  the 
  dorsal 
  area) 
  to 
  

   4 
  mm. 
  (in 
  the 
  costal 
  area) 
  distant 
  from 
  the 
  base. 
  At 
  the 
  

   end 
  of 
  the 
  second 
  third 
  is 
  an 
  indistinct, 
  horseshoe-shaped, 
  

   greyish-white, 
  transverse 
  figure, 
  the 
  convexity 
  of 
  which 
  is 
  

   directed 
  towards 
  the 
  margin 
  and 
  the 
  anterior 
  end 
  is 
  some- 
  

   what 
  dilated; 
  sometimes 
  perhaps 
  this 
  figure 
  is 
  divided 
  

   into 
  three 
  spots. 
  The 
  underside 
  of 
  the 
  primaries 
  and 
  the 
  

   ground-colour 
  of 
  the 
  secondaries 
  as 
  well 
  as 
  the 
  cilia 
  of 
  both
