  Like 
  D.

   smaller,

  hair

  The 
  females 
  are 
  labelled 
  April 
  1909. 
  The 
  genus 
  

   is 
  new 
  to 
  India. 
  

  

  In 
  Friese's 
  table 
  of 
  Palaearctic 
  species 
  the 
  Indian 
  species 
  

   falls 
  between 
  D. 
  plumipes 
  and 
  D. 
  panzeri, 
  having 
  rather 
  the 
  

   coloration 
  of 
  the 
  latter, 
  while 
  the 
  abdomen 
  is 
  formed 
  as 
  in 
  

   plumipes, 
  only 
  rather 
  more 
  slender 
  in 
  the 
  female, 
  con- 
  

   siderably 
  more 
  in 
  the 
  male. 
  In 
  the 
  female 
  the 
  third 
  

   antennal 
  joint 
  (about 
  425 
  p) 
  is 
  equal 
  to 
  the 
  next 
  two 
  com- 
  

   bined. 
  It 
  is 
  evident 
  that 
  D. 
  plumipes, 
  var. 
  flavescens, 
  Friese, 
  

   from 
  Egypt, 
  is 
  very 
  like 
  our 
  insect, 
  being 
  substantially 
  a 
  

   plumipes 
  coloured 
  like 
  panzeri; 
  but, 
  so 
  far 
  as 
  Friese's 
  account 
  

   shows, 
  the 
  legs 
  of 
  flavescens 
  are 
  as 
  in 
  plumipes, 
  and 
  the 
  

   colour-peculiarities 
  seem 
  to 
  be 
  confined 
  to 
  the 
  abdomen. 
  

   D. 
  yrohmanni, 
  Spinola, 
  from 
  Sicily, 
  has 
  the 
  legs 
  coloured 
  

   as 
  in 
  D. 
  comberi, 
  but 
  it 
  is 
  a 
  large 
  form 
  like 
  D. 
  visnaya.
