  type) 
  ; 
  Nimbin, 
  iv.1921 
  

   (Pemberton). 
  

  

  Described 
  from 
  four 
  specimens. 
  

  

  Very 
  similar 
  to 
  the 
  genotype, 
  A 
  T 
  . 
  cordipennis, 
  Lea, 
  the 
  only 
  species 
  described 
  up 
  

   to 
  the 
  present, 
  which 
  differs 
  in 
  the 
  following 
  particulars 
  : 
  — 
  The 
  scales 
  or 
  setae 
  are 
  

   throughout 
  much 
  shorter, 
  broader 
  and 
  quite 
  recumbent 
  ; 
  the 
  prothorax 
  is 
  slightly 
  

   transverse 
  ; 
  the 
  elytra 
  are 
  more 
  distinctly 
  striate, 
  with 
  the 
  intervals 
  more 
  regular 
  

   and 
  convex, 
  the 
  basal 
  sutural 
  depression 
  is 
  much 
  deeper, 
  every 
  puncture 
  bears 
  a 
  

   minute 
  granule 
  on 
  each 
  side 
  projecting 
  over 
  the 
  edge, 
  and 
  the 
  posterior 
  declivity 
  is 
  

   vertical 
  in 
  the 
  $ 
  ; 
  the 
  posterior 
  femora 
  bear 
  a 
  pale 
  patch 
  of 
  scales 
  externally 
  near 
  

   the 
  apex 
  ; 
  on 
  the 
  venter 
  of 
  the 
  $ 
  the 
  setae 
  are 
  short 
  and 
  recumbent, 
  the 
  basal 
  ventrite 
  

   is 
  merely 
  flattened 
  and 
  the 
  anal 
  one 
  is 
  convex 
  and 
  finely 
  rugulose. 
  

  

  Neosyagrius 
  striatus, 
  sp. 
  nov. 
  

  

  <J. 
  — 
  Integument 
  black 
  to 
  piceous, 
  shiny, 
  thinly 
  but 
  fairly 
  evenly 
  clothed 
  with 
  

   whitish 
  scales 
  and 
  golden-yellow 
  setae. 
  

  

  Elongate-ovate, 
  much 
  narrower 
  than 
  either 
  of 
  the 
  other 
  two 
  species, 
  from 
  which 
  it 
  

   differs 
  also 
  in 
  its 
  shiny 
  integument 
  and 
  more 
  deeply 
  striate 
  elytra 
  ; 
  moreover, 
  the 
  

   pronotum 
  is 
  less 
  flattened 
  and 
  the 
  sides 
  much 
  less 
  steep. 
  The 
  setae 
  on 
  the 
  prothorax 
  

   are 
  much 
  narrower 
  than 
  those 
  of 
  cordipennis, 
  and 
  even 
  rather 
  finer 
  than 
  those 
  of 
  

   porosus, 
  which 
  are 
  dark 
  brown 
  instead 
  of 
  golden-yellow. 
  The 
  elytra 
  are 
  broadest 
  at 
  

   about 
  one-fourth 
  from 
  the 
  base, 
  and 
  rapidly 
  narrowed 
  behind, 
  the 
  apex 
  being 
  obtusely 
  

   rounded 
  ; 
  the 
  punctures 
  bear 
  a 
  minute 
  granule 
  on 
  each 
  side 
  ; 
  the 
  scales 
  and 
  setae 
  

   are 
  narrower 
  and 
  more 
  evenly 
  distributed 
  than 
  in 
  the 
  other 
  two 
  species, 
  being 
  entirely 
  

   recumbent 
  ; 
  the 
  scutellar 
  depression 
  is 
  much 
  shallower 
  than 
  in 
  cordipennis, 
  and 
  there 
  

   are 
  no 
  transverse 
  elevations 
  as 
  in 
  porosus. 
  The 
  setae 
  on 
  the 
  femora 
  are 
  sparse, 
  narrow 
  

   and 
  recumbent, 
  and 
  there 
  is 
  no 
  pale 
  ring 
  ; 
  in 
  porosus 
  they 
  are 
  slightly 
  broader, 
  denser 
  

   and 
  not 
  quite 
  recumbent, 
  being 
  somewhat 
  curved 
  ; 
  whereas 
  in 
  cordipennis 
  they 
  are 
  

   very 
  broad 
  and 
  scale-like, 
  lie 
  quite 
  flat, 
  and 
  form 
  a 
  pale 
  ring 
  near 
  the 
  apex 
  on 
  the 
  

   posterior 
  pairs. 
  The 
  venter 
  of 
  the 
  £ 
  has 
  the 
  disk 
  of 
  the 
  first 
  visible 
  ventrite 
  flattened, 
  

   very 
  coarsely 
  punctate 
  and 
  shiny, 
  and 
  with 
  the 
  usual 
  two 
  tubercles 
  on 
  the 
  posterior 
  

   margin 
  ; 
  the 
  anal 
  ventrite 
  is 
  slightly 
  convex 
  in 
  the 
  middle 
  and 
  coarsely 
  punctate 
  ; 
  

   the 
  setae 
  are 
  short, 
  sparse, 
  narrow 
  and 
  recumbent.
