  Thorax. 
  Pronotum 
  collar-like, 
  consisting 
  of 
  2 
  triangular 
  tergites, 
  spiracular 
  

   emargination 
  slight 
  and 
  shallow 
  ; 
  pattern 
  fine, 
  long 
  drawn 
  out 
  transversely 
  ; 
  

   each 
  tergite 
  bears 
  5 
  bristles 
  ; 
  2 
  near 
  middle, 
  2 
  beside 
  the 
  spiracle 
  and 
  1 
  anteriorly. 
  

   Mesonotum 
  with 
  median 
  weak 
  line, 
  pattern 
  very 
  fine, 
  longitudinally 
  drawn 
  out 
  so 
  

   that 
  the 
  whole 
  surface 
  appears 
  to 
  be 
  delicately 
  striate 
  ; 
  1 
  stout 
  bristle 
  at 
  each 
  

   antero-lateral 
  angle 
  ; 
  parapsides 
  with 
  1 
  lateral 
  bristle 
  ; 
  axillae 
  with 
  2 
  minute 
  bristles 
  ; 
  

   scutellum 
  with 
  2 
  stout 
  bristles, 
  admedian 
  in 
  position, 
  1 
  beside 
  each 
  of 
  the 
  clear 
  

   sensory 
  pustules 
  (fig. 
  2). 
  Metanotum 
  very 
  short 
  and 
  broad, 
  the 
  propodeon 
  consists 
  

   of 
  a 
  median 
  area, 
  which 
  is 
  narrow 
  and 
  riband-like 
  and 
  2 
  lateral 
  triangular 
  expan- 
  

   sions 
  ; 
  spiracle 
  broadly 
  oval, 
  with 
  2 
  minute 
  bristles 
  outside 
  and 
  1 
  behind 
  (fig. 
  2). 
  

   The 
  mesophragma 
  extends 
  almost 
  through 
  three 
  segments 
  and 
  is 
  nearly 
  two-thirds 
  

   the 
  breadth 
  of 
  the 
  abdomen. 
  Prosternum 
  and 
  prcpleurae 
  bare. 
  Mesosternopleurae 
  

   smooth 
  and 
  bare 
  except 
  for 
  1 
  minute 
  bristle 
  at 
  the 
  posterior 
  edge 
  of 
  the 
  small 
  

   and 
  closely 
  united 
  prepectus 
  and 
  another 
  below 
  the 
  forewing 
  on 
  the 
  upper 
  edge 
  of 
  

   the 
  episternite.

  Wings. 
  Forewing 
  (fig. 
  3, 
  a) 
  (8 
  : 
  3) 
  : 
  length, 
  0-76 
  mm. 
  ; 
  breadth, 
  0-28 
  mm. 
  ; 
  "not 
  

   including 
  the 
  marginal 
  cilia, 
  of 
  which 
  the 
  longest 
  (0-125 
  mm.) 
  are 
  at 
  the 
  distal 
  

   posterior 
  angle. 
  The 
  longest 
  cilia 
  are 
  distinctly 
  not 
  half 
  the 
  greatest 
  breadth 
  of 
  

   the 
  wing, 
  though 
  they 
  are 
  two-thirds 
  or 
  more 
  as 
  long 
  again 
  as 
  the 
  radius. 
  The 
  

   neuration 
  reaches 
  to 
  rather 
  more 
  than 
  half 
  the 
  wing 
  length. 
  

  

  Hindwing 
  (fig. 
  3, 
  b) 
  (about 
  13 
  : 
  1) 
  : 
  length, 
  0-68 
  mm. 
  ; 
  breadth, 
  0-05 
  mm. 
  The 
  

   longest 
  of 
  the 
  marginal 
  cilia 
  are 
  three 
  times 
  the 
  breadth 
  (0-15 
  mm.). 
  Discal 
  cihation 
  

   as 
  in 
  figure, 
  the 
  second 
  row 
  being 
  just 
  in 
  advance 
  of 
  the 
  mid 
  line. 
  

  

  Legs. 
  Forelegs 
  : 
  length, 
  0-71 
  mm. 
  ; 
  1 
  stout 
  apical 
  femoral 
  bristle 
  ; 
  dorsal 
  

   edge 
  of 
  tibia 
  apparently 
  simple, 
  without 
  tooth-like 
  prominences 
  ; 
  first 
  tarsal 
  joint 
  

   with 
  about 
  6 
  lateral 
  ventral 
  spines.
