  long, 
  unusually 
  strong, 
  black, 
  acute 
  at 
  end 
  ; 
  inner 
  vt. 
  very 
  long, 
  more 
  than 
  twice 
  

   as 
  long 
  as 
  the 
  outer 
  ones, 
  strong, 
  curved 
  backwards 
  beyond 
  their 
  middle 
  ; 
  one 
  

   *. 
  or. 
  and 
  one 
  i. 
  or., 
  equally 
  strong 
  and 
  long 
  and 
  both 
  curved 
  backwards 
  ; 
  the 
  

   single 
  i. 
  or. 
  is 
  placed 
  much 
  in 
  front, 
  near 
  the 
  lunula 
  ; 
  oc. 
  strong, 
  but 
  not 
  very 
  long 
  ; 
  

   on 
  the 
  sides 
  of 
  frons 
  there 
  are 
  thus 
  only 
  two 
  pairs 
  of 
  bristles, 
  one 
  near 
  the 
  base 
  

   and 
  one 
  near 
  the 
  end 
  ; 
  genal 
  bristle 
  less 
  strong. 
  Thorax 
  proportionally 
  narrow, 
  

   less 
  convex 
  above, 
  shining 
  on 
  the 
  back, 
  with 
  the 
  suture 
  broadly 
  interrupted. 
  The 
  

   bristles 
  are 
  strong 
  and 
  the 
  chaetotaxy 
  is 
  complete, 
  except 
  the 
  scp., 
  which 
  are 
  not 
  

   distinct 
  ; 
  dc. 
  placed 
  only 
  a 
  little 
  behind 
  the 
  line 
  of 
  the 
  a. 
  sa. 
  ; 
  prsct. 
  only 
  a 
  little 
  

   closer 
  together 
  than 
  the 
  dc. 
  ; 
  one 
  mpl. 
  only 
  ; 
  pt. 
  and 
  st. 
  very 
  strong, 
  curved 
  upwards.. 
  

   Scutellum 
  triangular, 
  as 
  long 
  as 
  broad, 
  flat 
  above, 
  with 
  distinct 
  lateral 
  keels 
  ; 
  

   it 
  has 
  four 
  bristles, 
  the 
  basal 
  ones 
  very 
  strong 
  and 
  long, 
  the 
  apical 
  shorter, 
  thinner 
  

   and 
  decussate. 
  Abdomen 
  narrow 
  and 
  elongate, 
  not 
  narrowed 
  at 
  base, 
  with 
  about 
  

   parallel 
  sides 
  throughout 
  its 
  whole 
  length 
  ; 
  it 
  has 
  five 
  segments, 
  the 
  last 
  one 
  

   with 
  less 
  developed 
  bristles 
  ; 
  ovipositor 
  flattened, 
  triangular, 
  about 
  as 
  long 
  as 
  the 
  

   last 
  three 
  abdominal 
  segments 
  together. 
  Legs 
  proportionally 
  slender 
  and 
  bare 
  ; 
  

   front 
  femora 
  with 
  two 
  long 
  bristles 
  below 
  on 
  the 
  apical 
  fourth 
  ; 
  middle 
  tibiae 
  witk 
  

   a 
  single 
  spur 
  ; 
  hind 
  tibiae 
  destitute 
  of 
  a 
  distinct 
  row 
  of 
  bristly 
  hairs 
  on 
  the 
  outer 
  

   side. 
  Wings 
  of 
  usual 
  shape, 
  but 
  rather 
  narrow 
  at 
  base, 
  the 
  axillary 
  lobe 
  being 
  

   little 
  developed 
  and 
  the 
  alula 
  very 
  narrow. 
  They 
  have 
  a 
  characteristic 
  and 
  rather 
  

   aberrant 
  pattern 
  (for 
  the 
  group), 
  consisting 
  in 
  a 
  broad 
  infuscation 
  extending 
  almost 
  

   over 
  the 
  whole 
  wing, 
  with 
  the 
  fore 
  border 
  broadly 
  yellowish-hyaline 
  on 
  a 
  little 
  

   more 
  than 
  the 
  basal 
  half 
  ; 
  there 
  are 
  no 
  hyaline 
  spots, 
  and 
  no 
  hyaline 
  indentations. 
  

   Costa 
  not 
  ciliated 
  ; 
  with 
  a 
  short 
  but 
  strong 
  costal 
  bristle. 
  Auxiliary 
  vein 
  typical, 
  

   distinct 
  throughout, 
  with 
  diffuse 
  end 
  ; 
  stigma 
  short, 
  about 
  as 
  long 
  as 
  broad 
  ; 
  

   first 
  vein 
  hairy 
  and 
  rather 
  short, 
  ending 
  much 
  before 
  the 
  small 
  cross- 
  vein, 
  its 
  

   distance 
  from 
  the 
  end 
  of 
  the 
  second 
  vein 
  being 
  about 
  twice 
  as 
  long 
  as 
  that 
  of 
  the 
  

   second 
  from 
  the 
  third 
  vein. 
  Second 
  vein 
  in 
  its 
  last 
  half 
  strongly 
  diverging 
  from 
  

   the 
  third, 
  which 
  is 
  quite 
  straight 
  throughout 
  and 
  quite 
  bare. 
  Fourth 
  vein 
  straight 
  

   and 
  parallel 
  with 
  the 
  third 
  ; 
  small 
  cross-vein 
  placed 
  beyond 
  the 
  middle 
  of 
  the 
  long 
  

   discoidal 
  cell 
  ; 
  hind 
  cross-vein 
  straight, 
  perpendicular 
  and 
  rather 
  short, 
  being 
  

   shorter 
  than, 
  or 
  nearly 
  as 
  long 
  as 
  its 
  distance 
  from 
  the 
  small 
  one 
  ; 
  last 
  portion 
  

   of 
  the 
  fifth 
  vein 
  proportionally 
  long 
  and 
  strong 
  ; 
  sixth 
  vein 
  complete, 
  but 
  colour- 
  

   less 
  on 
  more 
  than 
  its 
  apical 
  half. 
  Second 
  basal 
  cell 
  but 
  little 
  developed 
  ; 
  anal 
  

   cell 
  broader 
  but 
  shorter 
  than 
  the 
  second 
  basal 
  cell, 
  with 
  an 
  acute 
  but 
  not 
  or 
  very 
  

   little 
  produced

  Type 
  : 
  the 
  following 
  new 
  species. 
  

  

  ASlofrypes 
  brevicornis, 
  sp. 
  nov. 
  (PL 
  xviii, 
  fig. 
  3). 
  

  

  A 
  narrow 
  elongate 
  species 
  not 
  unlike 
  some 
  forms 
  of 
  Aciura, 
  but 
  very 
  distinct 
  

   on 
  account 
  of 
  its 
  wholly 
  testaceous 
  thorax, 
  and 
  its 
  pecular 
  wing 
  pattern.

  Head 
  reddish 
  above, 
  pale 
  yellowish 
  below 
  ; 
  occiput 
  with 
  two 
  broad 
  shining 
  

   black 
  spots 
  of 
  triangular 
  shape,

  the 
  eye-border 
  and 
  the 
  narrow 
  

   apex 
  reaching 
  the 
  insertion 
  of 
  the 
  neck 
  ; 
  these 
  two 
  spots 
  are 
  separated 
  by 
  a 
  yellowish 
  

   triangle

  has 
  the 
  vertex 
  at 
  the 
  neck
