  DiPTERA. 
  

  

  Biting 
  Flies 
  on 
  the 
  Bababuddin 
  Hills. 
  (Tabanidse.) 
  

   During 
  the 
  month 
  of 
  May, 
  when 
  a 
  few 
  early 
  thunder 
  showers 
  have 
  

   fallen, 
  two 
  or 
  three 
  kinds 
  of 
  Tabanid 
  flies 
  of 
  the 
  genus 
  Hcematopota 
  

   are 
  generally 
  found 
  on 
  the 
  Bababuddin 
  Hills 
  in 
  Mysore. 
  These 
  flies 
  

   not 
  only 
  attack 
  cattle 
  but 
  bite 
  men 
  also 
  viciously. 
  During 
  this 
  season 
  

   cartmen 
  very 
  reluctantly 
  take 
  their 
  bulls 
  up 
  the 
  Hills. 
  While 
  on 
  a 
  

   collecting 
  trip 
  a 
  few 
  years 
  ago, 
  I 
  found 
  it 
  very 
  difficult 
  to 
  remain 
  on 
  

   the 
  hills 
  due 
  to 
  the 
  annoyance 
  of 
  these 
  insects. 
  Two 
  species 
  of 
  this 
  

   genus 
  collected 
  by 
  me 
  have 
  been 
  described 
  by 
  Miss 
  Ricardo 
  in 
  the 
  

   Annals 
  and 
  Magazine 
  of 
  Natural 
  History 
  for 
  February 
  1917 
  (p. 
  225) 
  as 
  

   H. 
  hindostani, 
  and 
  H. 
  montansis. 
  

  

  Pongamia 
  gall 
  fly. 
  (Cecidomyiadse). 
  (Plate 
  IV.) 
  

   In 
  many 
  parts 
  of 
  South 
  India, 
  especially 
  in 
  Bangalore, 
  Coimbatore, 
  

   and 
  other 
  places, 
  I 
  have 
  seen 
  that 
  the 
  fruits 
  of 
  the 
  tree 
  Pongamia 
  glabra, 
  

   which 
  under 
  normal 
  conditions 
  should 
  be 
  almond 
  shaped, 
  are 
  in 
  many 
  

   cases 
  found 
  deformed 
  into 
  clusters 
  of 
  small 
  round 
  gall 
  fruits. 
  On 
  the 
  

   same 
  tree 
  and 
  often 
  on 
  the 
  same 
  branch 
  both 
  the 
  kinds 
  of 
  fruits 
  are 
  

   commonly 
  formed. 
  For 
  a 
  long 
  time 
  I 
  thought 
  the 
  growth 
  was 
  natural. 
  

   Recently 
  I 
  found 
  that 
  this 
  small 
  round 
  gall 
  fruit 
  was 
  a 
  mal-formation 
  

   and 
  due 
  to 
  the 
  work 
  of 
  a 
  gall-fly. 
  I 
  have 
  reared 
  out 
  the 
  flies 
  in 
  numbers 
  

   and 
  specimens 
  have 
  been 
  forwarded 
  to 
  Dr. 
  E. 
  P. 
  Felt 
  for 
  identification. 
  

   It 
  is 
  probably 
  common 
  in 
  other 
  parts 
  of 
  India 
  also. 
  

  

  Rhynchota. 
  

  

  Deltocephalus 
  dorsalis, 
  Mot. 
  (Jassidae). 
  (Plate 
  V, 
  fit/. 
  1.) 
  

   Though 
  this 
  leaf-hopper 
  has 
  been 
  recorded 
  as 
  enjoying 
  a 
  fairly 
  wide 
  

   distribution, 
  it 
  has 
  not 
  been 
  noted 
  as 
  an 
  injurious 
  insect 
  till 
  now. 
  In 
  

   June 
  1919 
  this 
  insect 
  was 
  found 
  in 
  swarms 
  on 
  a 
  paddy 
  nursery 
  in 
  the 
  

   Kistna 
  Delta 
  and 
  so 
  far 
  as 
  I 
  could 
  judge 
  appeared 
  to 
  be 
  responsible 
  

   for 
  the 
  damage 
  to 
  the 
  foliage 
  which 
  was 
  characteristic 
  of 
  leaf-hopper 
  

   bugs 
  and 
  which 
  resembles 
  exactly 
  that 
  caused 
  by 
  Nepkotettix 
  hipunc- 
  

   tatus 
  on 
  paddy. 
  

  

  Disphinctus 
  humeralis, 
  Dist. 
  (Capsidae. 
  ) 
  

   This 
  insect 
  has 
  not 
  been 
  recorded 
  from 
  South 
  India 
  till 
  now. 
  I 
  

   noted 
  it 
  in 
  some 
  numbers 
  on 
  a 
  species 
  of 
  wild 
  Solanum 
  on 
  the 
  Wynaad 
  

   Hills 
  (2,500 
  feet 
  elevation) 
  in 
  October. 
  This 
  is 
  an 
  insect 
  which
