  NONGOMA, 
  n. 
  gen. 
  

  

  Mentum 
  ovate 
  laterally 
  and 
  with 
  the 
  apical 
  part 
  a 
  little 
  more 
  

   attenuate 
  than 
  in 
  Anomala, 
  but 
  similarly 
  impressed 
  in 
  the 
  outer 
  

   face 
  ; 
  palpi 
  also 
  similar 
  in 
  shape 
  ; 
  maxillae 
  not 
  dentate 
  but 
  produced 
  

   into 
  an 
  inflexed 
  transverse 
  lobe 
  emarginate 
  in 
  the 
  middle 
  ; 
  the 
  shape 
  

   and 
  sculpture 
  of 
  the 
  body 
  are 
  similar 
  to 
  those 
  of 
  Anomala, 
  but 
  the 
  

   hind 
  tibiae 
  are 
  gradually 
  ampliated 
  triangularly 
  from 
  the 
  base 
  to 
  the 
  

   apex, 
  and 
  the 
  two 
  apical 
  spurs 
  are 
  more 
  laminate, 
  more 
  parallel 
  and 
  

   longer 
  ; 
  the 
  club 
  of 
  the 
  antennae, 
  which 
  are 
  nine-jointed, 
  is 
  in 
  the 
  

   male 
  as 
  long 
  as 
  all 
  the 
  other 
  joints 
  taken 
  together, 
  the 
  inner 
  claw 
  

   of 
  the 
  anterior 
  and 
  intermediate 
  tarsi 
  is 
  simple 
  in 
  both 
  sexes, 
  and 
  

   all 
  the 
  claws 
  are 
  of 
  nearly 
  equal 
  length.

  Either 
  pale 
  testaceous 
  with 
  two 
  slightly 
  fuscous 
  supra-lateral 
  

   longitudinal 
  patches 
  on 
  the 
  prothorax, 
  or 
  totally 
  testaceous, 
  but 
  with 
  

   the 
  head 
  infuscate, 
  or 
  having 
  two 
  large 
  longitudinal 
  fuscous 
  patches 
  

   on 
  the 
  prothorax 
  and 
  a 
  very 
  broad 
  discoidal 
  one 
  extending 
  from 
  the 
  

   suture 
  of 
  the 
  elytra 
  to 
  about 
  the 
  median 
  dorsal 
  part, 
  as 
  well 
  as 
  one 
  

   or 
  two 
  narrow 
  ones 
  above 
  the 
  outer 
  margin 
  ; 
  head 
  deeply 
  but 
  not 
  

   roughly 
  punctured, 
  scutellum 
  straight 
  laterally, 
  arcuate 
  in 
  front 
  and 
  

   with 
  the 
  margin 
  distinctly 
  reflexed, 
  it 
  is 
  covered 
  with 
  round 
  not 
  

   closely 
  set 
  punctures, 
  and 
  is 
  not 
  at 
  all 
  shagreened 
  ; 
  in 
  some 
  examples 
  

   the 
  punctures 
  are 
  almost 
  indistinct 
  on 
  the 
  head 
  and 
  on 
  the 
  clypeus 
  ; 
  

   prothorax 
  punctulate 
  with 
  the 
  punctures 
  set 
  more 
  closely 
  on 
  the 
  

   sides, 
  and 
  having 
  occasionally 
  a 
  median 
  longitudinal 
  impressed 
  line 
  ; 
  

   scutellum 
  punctulate 
  ; 
  elytra 
  deeply 
  punctato- 
  striate, 
  with 
  the 
  

   intervals 
  costulate 
  in 
  the 
  dorsal 
  part 
  and 
  with 
  the 
  irregularly 
  

   pluri-seriate 
  punctures 
  on 
  the 
  third 
  interval 
  reaching 
  to 
  a 
  very 
  short 
  

   distance 
  ; 
  pygidium 
  densely 
  cicatricoso-punctate 
  ; 
  pectus 
  very 
  

   densely 
  hairy; 
  anterior 
  tibiae 
  bi-dentate 
  outwardly, 
  apical 
  tooth 
  

   very 
  long 
  and 
  nearly 
  straight. 
  

  

  This 
  species 
  is 
  very 
  variable 
  not 
  only 
  in 
  colouration 
  but 
  also 
  in 
  the 
  

   sculpture 
  of 
  the 
  head, 
  prothorax, 
  and 
  scutellum, 
  which, 
  in 
  some 
  

   examples, 
  are 
  hardly 
  distinctly 
  punctulate.
