  Bingham 
  U.c, 
  p. 
  65) 
  has 
  been 
  unable 
  to 
  assign 
  the 
  males 
  

   of 
  the 
  Indian 
  species 
  to 
  their 
  respective 
  females, 
  and 
  

   describes 
  7 
  males 
  and 
  7 
  females 
  as 
  distinct 
  species. 
  

   Doubtless 
  direct 
  observation 
  will 
  be 
  necessary 
  to 
  unite.the 
  

   sexes 
  correctly 
  ; 
  and, 
  in 
  default 
  of 
  this 
  information, 
  there 
  

   is 
  no 
  course 
  open 
  but 
  to 
  treat 
  them 
  as 
  distinct 
  species. 
  

   Of 
  males, 
  no 
  species 
  is 
  described 
  with 
  red 
  on 
  the 
  abdomen 
  ; 
  

   but 
  of 
  females, 
  there 
  are 
  three 
  with 
  the 
  abdomen 
  red 
  

   wholly 
  or 
  in 
  part. 
  Of 
  these 
  the 
  present 
  species 
  comes 
  

   nearest 
  to 
  M. 
  mandalensis 
  Magretti, 
  but 
  that 
  has 
  segments 
  

   1-5 
  of 
  the 
  abdomen 
  red 
  and 
  both 
  wings 
  hyaline 
  at 
  the 
  

   base, 
  the 
  anal 
  segments 
  fuscous, 
  the 
  posterior 
  wings 
  

   "hyaline, 
  the 
  extreme 
  apex 
  somewhat 
  fuscescent," 
  the 
  

   tegular
