  keel. 
  Legs, 
  especially 
  the 
  tibiae 
  and 
  tarsi, 
  very 
  thickly 
  

   covered 
  with 
  stiff, 
  black 
  hairs. 
  Wings 
  uniformly 
  coloured, 
  

   except 
  for 
  a 
  small 
  hyaline 
  spot 
  at 
  the 
  base 
  of 
  the 
  cubital, 
  

   and 
  a 
  more 
  elongated 
  one 
  touching 
  the 
  lower 
  part 
  of 
  the 
  

   discoidal 
  nervure 
  in 
  front 
  ; 
  the 
  transverse 
  median 
  nervure 
  

   is 
  received 
  immediately 
  in 
  front 
  of 
  the 
  basal 
  nervure, 
  

   almost 
  touching 
  it. 
  Abdomen 
  smooth, 
  shining; 
  the 
  petiole 
  

   depressed 
  at 
  the

  triangularly 
  

   raised.

  The 
  two 
  species 
  here 
  described 
  agree 
  better 
  with 
  this 
  

   genus 
  rather 
  than 
  with 
  Earinus, 
  with 
  which 
  they 
  agree 
  in 
  

   some 
  other 
  respects. 
  They 
  agree 
  also 
  with 
  DisopJirys 
  

   in 
  the 
  second 
  transverse 
  cubital 
  nervure 
  emitting 
  a 
  short 
  

   branch, 
  and 
  one 
  of 
  the 
  species 
  {tuberculatus) 
  approximates 
  

   to 
  it 
  by 
  having 
  a 
  horn 
  between 
  the 
  antennae. 
  Apart 
  from 
  

   the 
  marked 
  distinction 
  in 
  coloration 
  our 
  two 
  species 
  may 
  

   be 
  separated 
  as 
  follows 
  : 
  — 
  

  

  A 
  stout 
  tubercle 
  berween 
  the 
  antennae, 
  the 
  meso- 
  

  

  pleural 
  suture 
  smooth. 
  M. 
  tuberculatus. 
  

  

  No 
  tubercle 
  between 
  the 
  antennas, 
  the 
  mesopleural 
  

  

  furrow 
  bearing 
  oblique 
  keels.

  Antennae 
  as 
  long 
  as 
  the

  the

   Head 
  shining, 
  impunctate; 
  the 
  face 
  sparsely 
  covered 
  with 
  

   short,

  hair

  the 
  palpi 
  are 
  thickly 
  covered 
  with 
  

   long, 
  white 
  hair 
  ; 
  between 
  the 
  antennae 
  is 
  a 
  stout 
  plate, 
  

   which 
  becomes 
  gradually 
  smaller 
  behind 
  and 
  is 
  rounded 
  

   in
