  (J.

  Head 
  : 
  The 
  £ 
  differs 
  conspicuously 
  from 
  the 
  $ 
  and 
  from 
  the 
  (Jc? 
  of 
  the 
  

   other 
  species 
  now 
  described 
  in 
  the 
  antennae 
  (fig. 
  4, 
  a, 
  b). 
  These 
  are 
  apparently 
  com- 
  

   posed 
  of 
  six 
  joints 
  ; 
  scape, 
  pedicel, 
  ring 
  joint, 
  two 
  funicular 
  and 
  one 
  club. 
  The 
  

   scape 
  is 
  extremely 
  thick, 
  deep 
  and 
  swollen, 
  the 
  length 
  being 
  to 
  the 
  breadth 
  as 
  8 
  : 
  5. 
  

   Pedicel 
  normal, 
  five- 
  twelfths 
  of 
  the 
  scape 
  in 
  length. 
  First 
  funicular 
  joint 
  cylindrical, 
  

   longer 
  (7 
  : 
  5) 
  and 
  narrower 
  (3 
  : 
  4) 
  than 
  the 
  more 
  globose 
  second 
  joint. 
  Club 
  joint 
  

   single, 
  swollen, 
  oval, 
  without 
  terminal 
  spur, 
  longer 
  than 
  broad 
  (4 
  : 
  3) 
  and 
  shorter 
  

   than 
  the 
  sum 
  of 
  the 
  funicular 
  joints 
  (2 
  : 
  3), 
  The 
  whole 
  antenna 
  is 
  bristly 
  (except 
  the 
  

   sparsely 
  clad 
  pedicel), 
  and 
  the 
  scape, 
  besides 
  being 
  covered 
  dorsally 
  with 
  a 
  coarse 
  

   raised 
  reticulation, 
  bears 
  near 
  the 
  apex 
  a 
  perforated 
  oval 
  plate.

  the

  orewings,

  much 
  less

   shorter. 
  

  

  Legs 
  rather 
  stronger

  possibly 
  more

  The

  trifle 
  wider,

  posteriorly.
