  Very 
  like 
  P. 
  minutus 
  var. 
  africanus, 
  Newst., 
  but 
  both 
  sexes 
  may 
  be 
  distinguished 
  

   at 
  once 
  by 
  the 
  great 
  length 
  of 
  the 
  3rd 
  segment 
  of 
  the 
  antennae, 
  which, 
  in 
  the 
  <}, 
  is 
  

   twice 
  the 
  length 
  of 
  the 
  proboscis 
  proper 
  (i.e., 
  exclusive 
  of 
  the 
  clypeus), 
  the 
  distal 
  

   portion 
  of 
  which 
  projects 
  beyond 
  the 
  tip 
  of 
  the 
  latter. 
  The 
  wings 
  in 
  both 
  sexes 
  

   are 
  broader 
  than 
  they 
  are 
  in 
  africanus, 
  and 
  less 
  pointed, 
  the 
  tip 
  of 
  the 
  first 
  longi- 
  

   tudinal 
  vein 
  also 
  extends 
  much 
  further 
  forward, 
  overlapping 
  the 
  anterior 
  branch 
  

   of 
  the 
  second 
  vein 
  by 
  about 
  half 
  its 
  length 
  ; 
  generally 
  both 
  sexes 
  are 
  also 
  much 
  larger 
  

   and 
  the 
  females 
  decidedly 
  darker.

  equal
