  as 
  long 
  as 
  the 
  prothorax, 
  almost 
  straight, 
  very 
  shiny 
  and 
  sparsely 
  punctate, 
  the 
  

   base 
  clothed 
  with 
  white 
  hairs. 
  Antennae 
  inserted 
  quite 
  close 
  to 
  the 
  base 
  

   of 
  the 
  rostrum, 
  the 
  scape 
  strongly 
  clavate 
  and 
  short, 
  about 
  as 
  long 
  as 
  the 
  

   first 
  two 
  funicular 
  joints 
  ; 
  the 
  funicle 
  6- 
  jointed, 
  joint 
  1 
  much 
  longer 
  and 
  

   stouter 
  than 
  any 
  of 
  the 
  others 
  and 
  clavate, 
  2 
  and 
  3 
  sub 
  equal 
  and 
  longer 
  

   than 
  broad, 
  the 
  remainder 
  becoming 
  shorter 
  and 
  more 
  transverse 
  ; 
  the 
  club 
  

   ovate, 
  the 
  apex 
  blunt. 
  Prothorax 
  transverse, 
  broadest 
  at 
  the 
  base 
  and 
  strongly 
  

   narrowed 
  anteriorly, 
  the 
  sides 
  quite 
  straight 
  and 
  without 
  any 
  apical 
  constriction, 
  

   the 
  basal 
  margin 
  roundly 
  produced 
  in 
  the 
  centre, 
  the 
  upper 
  surface 
  rather 
  coarsely 
  

   punctate 
  throughout. 
  Scutellum 
  with 
  a 
  few 
  white 
  hairs. 
  Elytra 
  oval, 
  the 
  sides 
  

   regular 
  rounded, 
  the 
  shoulders 
  very 
  oblique, 
  broadest 
  before 
  the 
  middle, 
  the 
  apices 
  

   separately 
  rounded 
  ; 
  shallowly 
  striate, 
  the 
  striae 
  indistinctly 
  punctate, 
  the 
  intervals 
  

   scarcely 
  convex, 
  coriaceous 
  and 
  shiny 
  ; 
  the 
  white 
  hairs 
  so 
  sparse 
  as 
  hardly 
  to 
  conceal 
  

   the 
  integument, 
  the 
  black 
  ones 
  arranged 
  for 
  the 
  most 
  part 
  in 
  two 
  rows 
  on 
  each 
  

   interval. 
  Legs 
  pale 
  yellow, 
  thinly 
  clothed 
  with 
  white 
  hairs, 
  the 
  posterior 
  femora 
  

   very 
  large, 
  their 
  lower 
  edge 
  armed 
  with 
  two 
  distant 
  small 
  black 
  spines, 
  and 
  beside 
  

   these 
  a 
  row 
  of 
  6 
  to 
  9 
  very 
  minute 
  black 
  spines, 
  the 
  posterior 
  tibiae 
  with 
  a 
  horseshoe- 
  

   shaped 
  comb 
  of 
  black 
  teeth 
  at 
  the 
  apex.

  The 
  specimens 
  before 
  me 
  (from 
  Guntur) 
  have 
  all 
  been 
  bred, 
  and 
  it 
  seems 
  possible 
  

   that 
  the 
  colouring 
  of 
  the 
  elytra 
  is 
  not 
  fully 
  developed 
  ; 
  it 
  is 
  probably 
  darker 
  in 
  

   normal 
  specimens. 
  

  

  The 
  larvae 
  of 
  this 
  beetle 
  bore 
  in 
  the 
  leaves 
  of 
  the 
  mango 
  tree, 
  and 
  an 
  account 
  of 
  

   their 
  life- 
  history 
  has 
  already 
  been 
  published 
  by 
  Mr. 
  T. 
  Bainbrigge 
  Fletcher 
  (" 
  Some 
  

   South 
  Indian 
  Insects," 
  p. 
  334, 
  1914). 
  He 
  says 
  that 
  the 
  insect 
  is 
  " 
  a 
  minor 
  pest 
  of 
  

   local 
  importance. 
  As 
  many 
  as 
  20-30 
  larvae 
  may 
  be 
  found 
  in 
  one 
  leaf 
  and 
  such 
  

   leaves 
  .... 
  dry 
  up 
  completely 
  ; 
  in 
  such 
  cases 
  a 
  good 
  deal 
  of 
  damage 
  may 
  be 
  done. 
  

   The 
  beetles 
  also 
  may 
  cut 
  small 
  holes 
  in 
  the 
  leaves, 
  but 
  the 
  damage 
  thus 
  done 
  is 
  

   inconsiderable." 
  

  

  Pachytychius 
  mungonis, 
  sp. 
  nov. 
  

  

  Pitch-brown, 
  the 
  prothorax 
  with 
  dark 
  brown 
  scales, 
  some 
  of 
  which 
  are 
  paler 
  

   towards 
  the 
  sides, 
  and 
  with 
  a 
  narrow 
  central 
  stripe 
  of 
  whitish 
  scales 
  ; 
  the 
  elytra 
  

   with 
  fairly 
  dense 
  light 
  brown 
  scaling 
  and 
  with 
  large 
  confluent 
  patches 
  of 
  creamy 
  

   white 
  scales, 
  except 
  on 
  the 
  first 
  two 
  intervals. 
  

  

  Head 
  deeply 
  set 
  in 
  the 
  prothorax, 
  and 
  closely 
  and 
  coarsely 
  punctate 
  throughout. 
  

   Rostrum 
  moderately 
  stout 
  and 
  strongly 
  curved, 
  with 
  six 
  closely 
  punctate 
  deep 
  sulci, 
  

   the 
  external 
  ones 
  being 
  much 
  broader 
  than 
  the 
  others 
  in 
  the 
  basal 
  half, 
  the 
  intervals 
  

   convex, 
  smooth 
  and 
  shiny, 
  with 
  occasional 
  isolated 
  punctures 
  ; 
  in 
  the 
  <J 
  both 
  the 
  

   internal 
  and 
  external 
  pairs 
  of 
  sulci 
  reach 
  the 
  apex, 
  the 
  intermediate 
  pair 
  only 
  reaching 
  

   the 
  antennae 
  ; 
  in 
  the 
  9. 
  the 
  internal 
  pair 
  of 
  sulci 
  scarcely 
  reach 
  the 
  antennae, 
  being 
  

   continued 
  to 
  the 
  apex 
  in 
  the 
  form 
  of 
  a 
  row 
  of 
  punctures. 
  Prothorax 
  much 
  broader 
  

   than 
  long, 
  the 
  sides 
  moderately 
  rounded, 
  broadest 
  in 
  front 
  of 
  the 
  middle, 
  abruptly 
  

   narrowed 
  and 
  slightly 
  constricted 
  at 
  the 
  apex, 
  the 
  basal 
  margin 
  shallowly 
  bisinuate 
  ; 
  

   the 
  dorsal 
  surface 
  very 
  closely 
  and 
  evenly 
  punctate 
  throughout, 
  but 
  sometimes 
  with
