  I'othneyi, 
  as 
  

   also 
  in 
  having 
  in 
  the 
  wings 
  three 
  clouds, 
  but 
  abundantly 
  

   distinct 
  in 
  structure. 
  The 
  clypeus 
  at 
  the 
  apex 
  is 
  shining, 
  

   and 
  transverse 
  in 
  the 
  middle 
  ; 
  the 
  elongated 
  ridges 
  above 
  the 
  

   antennae, 
  so 
  prominent 
  in 
  RotJnieyi, 
  are 
  absent, 
  as 
  is 
  also 
  the 
  

   shining 
  fovea, 
  but 
  there 
  is 
  a 
  small 
  carina 
  there 
  ; 
  the 
  eyes 
  dis- 
  

   tinctly 
  diverge 
  beneath 
  ; 
  the 
  ocelli 
  are 
  in 
  a 
  triangle, 
  and 
  closer 
  

   to 
  each 
  other 
  ; 
  the 
  hinder 
  being 
  separated 
  from 
  the 
  eyes 
  by 
  

   twice 
  the 
  distance 
  they 
  are 
  from 
  each 
  other 
  ; 
  the 
  median 
  

   segment 
  at 
  the 
  apex 
  is 
  more 
  abrupt 
  ; 
  the 
  abdomen 
  is 
  longer, 
  

   being 
  as 
  long 
  as 
  the 
  head 
  and 
  thorax 
  united, 
  and 
  its 
  apical 
  

   segments 
  are 
  not 
  so 
  thickly 
  haired 
  ; 
  the 
  form 
  of 
  the 
  second 
  

   cubital 
  cellule 
  is 
  very 
  different 
  ; 
  the 
  first 
  transverse 
  cubital 
  

   nervure 
  is 
  elbowed 
  at 
  the 
  middle, 
  and 
  bends 
  towards 
  the 
  

   second, 
  making 
  the 
  top 
  of 
  the 
  cellule 
  there 
  about 
  one-fourth 
  

   of 
  what 
  it 
  is 
  at 
  the 
  bottom, 
  and 
  about 
  one-third 
  of 
  the 
  length 
  

   of 
  the 
  top 
  of 
  the 
  third 
  ; 
  at 
  the 
  bottom, 
  the 
  second 
  cubital 
  

   cellule 
  is 
  about 
  three-fourths 
  of 
  the 
  length 
  of 
  the 
  third 
  ; 
  the 
  

   second 
  transverse 
  cubital 
  nervure 
  is 
  sharply 
  elbowed 
  at 
  the 
  

   top, 
  making 
  the 
  cellule 
  much 
  narrower 
  at 
  the 
  top 
  than 
  at 
  

   the 
  bottom, 
  where 
  it 
  is 
  rounded 
  broadly 
  at 
  the 
  apex, 
  instead 
  

   of 
  acutely 
  angled 
  as 
  in 
  Rothneyi, 
  while 
  the 
  cubital 
  nervure 
  

   terminates 
  completely 
  there 
  ; 
  the 
  first 
  recurrent 
  nervure 
  

   is 
  received 
  a 
  very 
  little 
  beyond 
  the 
  middle; 
  the 
  second 
  at 
  a 
  

   less 
  distance 
  from 
  the 
  transverse 
  cubital 
  nervure 
  than 
  is 
  the 
  

   first 
  ; 
  the 
  radial 
  nervure 
  becomes 
  elbowed 
  about 
  the 
  basal 
  

   third 
  (and 
  also 
  more 
  sharply), 
  while 
  in 
  Rotlineyi 
  it 
  turns 
  up 
  

   at 
  the 
  middle 
  of 
  the 
  cellule. 
  5. 
  cotcsi 
  also 
  is 
  larger, 
  being 
  

   13 
  mm. 
  in 
  length. 
  The 
  long 
  spur 
  of 
  the 
  hind 
  tibisG 
  does 
  

   not 
  reach 
  the 
  middle 
  of 
  metatarsus 
  ; 
  the 
  tibial 
  spines 
  are 
  

   shorter 
  and 
  fewer.
