   ing 
  considerably 
  the 
  hind 
  femora, 
  gently 
  and 
  feebly 
  tapering 
  from 
  the 
  

   subbasal 
  expansion 
  to 
  the 
  Avell-ronnded 
  tip, 
  fusco-testaceous 
  with 
  an 
  

   olivaceous 
  tinge, 
  distantly

  roundish 
  

   or 
  subquadrate 
  dark 
  fuscous 
  spots, 
  less 
  abundant 
  in 
  the 
  apical 
  third, 
  

   but 
  not 
  confined 
  at 
  all 
  to 
  the 
  discoidal 
  area; 
  wings 
  smoky 
  pellucid, 
  

   becoming 
  feebly 
  infusc^ated 
  apically, 
  the 
  veins 
  and 
  cross- 
  veins 
  mostly 
  

   blackish 
  fuscous. 
  Fore 
  and 
  middle 
  femora 
  luteo-ferruginous, 
  flecked 
  

   with 
  dark 
  olivaceous 
  or 
  fuscous; 
  hind 
  femora 
  varying 
  from 
  sordid 
  

   luteo-fuscous 
  to 
  dull 
  pale 
  olivaceous, 
  rather 
  narrowly 
  and 
  completely 
  

   bifasciate 
  with 
  black, 
  forming 
  unusually 
  regular 
  transverse 
  bauds, 
  the 
  

   whole 
  apex 
  blackish 
  fuscous 
  or 
  black 
  ; 
  hind 
  tibiae 
  plumbeo-fuscous 
  at 
  

   extreme 
  base, 
  followed 
  by 
  a 
  very 
  narrow 
  black 
  annulus 
  and 
  this 
  by 
  a 
  

   broader 
  pale 
  annulus, 
  beyond 
  which 
  the 
  tibiae 
  are 
  dull 
  red, 
  obscured 
  

   above, 
  excepting 
  at 
  apex, 
  and 
  sometimes 
  on 
  the 
  sides 
  for 
  a 
  similar 
  and 
  

   beneatli 
  for 
  a 
  brief 
  distance, 
  witli 
  fuscous, 
  often 
  broken 
  into 
  flecks, 
  

   the 
  whole 
  pilose 
  above; 
  spines 
  black 
  nearly 
  or 
  quite 
  to 
  their 
  base, 
  

   ten 
  to 
  twelve 
  in 
  number 
  in 
  the 
  outer 
  series. 
  Extremity 
  of 
  male 
  abdo- 
  

   men 
  feebly 
  clavate, 
  much 
  upturned, 
  the 
  supraanal 
  plate 
  broad, 
  triangu- 
  

   lar, 
  with 
  nearly 
  straight 
  lateral 
  margins, 
  acutangulate 
  tip 
  (too 
  nearly 
  

   rectangulate 
  in 
  our 
  figure), 
  with 
  a 
  broad 
  and 
  rather 
  shallow 
  median 
  

   sulcus, 
  interrupted 
  beyond 
  the 
  middle, 
  and 
  in 
  the 
  basal 
  half 
  bounded 
  

   by 
  moderately 
  high 
  walls; 
  furcula 
  composed 
  of 
  a 
  pair 
  of 
  slight 
  trian- 
  

   gular 
  projections 
  at 
  the 
  inner 
  angles 
  of 
  the 
  divided 
  last 
  dorsal 
  segment, 
  

   overlying 
  the 
  ridges 
  of 
  the 
  supraanal 
  plate; 
  cerci 
  large, 
  subequal 
  on 
  the 
  

   ba^^al 
  two-fifths 
  or 
  more, 
  then 
  abruptly 
  expanding 
  into 
  a 
  transverse 
  

   apical 
  flap, 
  twice 
  as 
  broad 
  as 
  the 
  base, 
  the 
  expansion 
  almost 
  wholly 
  on 
  

   the 
  upper 
  side 
  and 
  at 
  right 
  angles 
  to 
  the 
  basal 
  portion, 
  the 
  apical 
  

   margin 
  broadly 
  convex, 
  but 
  below 
  emarginate 
  to 
  form 
  a 
  denticulation 
  

   of 
  the 
  lower 
  posterior 
  angle 
  of 
  the 
  flap, 
  the 
  whole 
  gently 
  incurved 
  

   and 
  surpassing 
  the 
  supraanal 
  plate 
  ; 
  infracercal 
  plates 
  wholly 
  concealed 
  

   beneath 
  the 
  supraanal 
  plate; 
  subgenital 
  plate 
  moderately 
  broad, 
  very 
  

   greatly 
  extended 
  and 
  abruptly 
  elevated 
  at 
  the 
  extreme 
  apex.

  This 
  species 
  is 
  certainly 
  very 
  closely 
  allied 
  to 
  M. 
  inmctidatus, 
  which 
  

   not 
  only 
  occurs 
  with 
  it, 
  but 
  over 
  a 
  much 
  wider 
  extent 
  of 
  country; 
  it 
  is 
  

   a 
  much 
  larger 
  insect 
  and 
  differs 
  in 
  several 
  points 
  in 
  the 
  abdominal 
  

   appendages 
  of 
  the 
  male, 
  though 
  it 
  is 
  possible 
  that 
  the 
  two 
  should 
  be 
  

   looked 
  upon 
  as 
  races 
  of 
  a 
  single 
  species.
