  REVISION 
  OF 
  THE 
  MELAXOrLI—SCUDDER.

  This 
  species 
  is 
  remarkable 
  for 
  the 
  slenderuess 
  of 
  the 
  fore 
  and 
  middle 
  

   femora 
  of 
  the 
  male 
  and 
  the 
  brevity 
  of 
  the 
  cerci, 
  exposing 
  so 
  fully 
  the 
  

   infracercal 
  plates; 
  it 
  has 
  considerably 
  longer 
  hind 
  legs 
  than 
  B. 
  re/erta, 
  

   which 
  it 
  most 
  resembles 
  in 
  general 
  appearance.

  Body 
  stout, 
  compact, 
  transversely 
  subquadrate, 
  thinly 
  pilose. 
  Head 
  

   large, 
  broad, 
  a 
  little 
  prominent, 
  with 
  the 
  eyes 
  fully 
  as 
  wide, 
  at 
  least 
  in 
  

   the 
  male, 
  as 
  the 
  length 
  of 
  the 
  lateral 
  carinae 
  of 
  the 
  metazona, 
  the 
  sum- 
  

   mit 
  well 
  arched, 
  raised 
  a 
  little 
  above 
  the 
  level 
  of 
  the 
  pronotum, 
  the 
  

   fastigium 
  rapidly 
  descending 
  and 
  forming 
  an 
  obtuse 
  angle 
  with 
  the 
  very 
  

   straight 
  and 
  slightly 
  receding 
  fiice; 
  eyes 
  rather 
  small 
  but 
  very 
  promi- 
  

   nent 
  in 
  both 
  sexes, 
  nearly 
  as 
  broad 
  as 
  long 
  and 
  no 
  longer 
  (female) 
  or 
  

   scarcely 
  longer 
  (male) 
  than 
  the 
  anterior 
  intraocular 
  portion 
  of 
  the 
  

   geuae; 
  interspace 
  between 
  the 
  eyes 
  exceptionally 
  broad, 
  in 
  the 
  female 
  

   nearly 
  as 
  broad 
  as 
  the 
  upper 
  aspect 
  of 
  the 
  eyes; 
  fastigium 
  feebly 
  con- 
  

   vex 
  as 
  far 
  as 
  the 
  front 
  margin 
  of 
  the 
  eyes, 
  in 
  front 
  of 
  which 
  it 
  is 
  

   depressed; 
  frontal 
  costa 
  only 
  moderately 
  bioad, 
  much 
  narrower 
  than 
  

   the 
  interspace 
  between 
  the 
  eyes, 
  obsolescent 
  below 
  the 
  ocellus; 
  owing 
  

   to 
  the 
  breadth 
  of 
  the 
  face, 
  the 
  lateral 
  carinae 
  are 
  more 
  than 
  usually 
  

   divergent; 
  antennae 
  slender, 
  long, 
  about 
  half 
  as 
  long 
  as 
  the 
  body, 
  even 
  

   in 
  the 
  female. 
  Pronotum 
  feebly 
  subsellate, 
  the 
  anterior 
  margin 
  ilaring 
  

   to 
  receive 
  the 
  head, 
  and 
  the 
  metazona 
  both 
  expanding 
  and 
  having 
  its 
  

   dorsum 
  raised 
  at 
  a 
  slight 
  angle 
  with 
  the 
  prozona; 
  front 
  margin 
  slightly 
  

   convex; 
  hind 
  margin 
  slightly 
  more 
  convex, 
  feebly 
  emaiginate, 
  even 
  in 
  

   the 
  macropterous 
  forms; 
  disk 
  of 
  prozona 
  feebly 
  convex 
  transversely, 
  

   of 
  metazona 
  plane, 
  passing 
  with 
  a 
  distinct 
  angle 
  into 
  the 
  vertical 
  lateral 
  

   lobes, 
  more 
  distinct 
  on 
  metazona 
  than 
  on 
  j)rozona, 
  so 
  that, 
  at 
  least 
  on 
  

   the 
  metazona, 
  there 
  are 
  distinct 
  lateral 
  carinae, 
  besides 
  a 
  well-detincd 
  

   percurrent, 
  median 
  carina; 
  j^rozona 
  smooth 
  excepting 
  its 
  subrugose 
  

   anterior 
  margin, 
  subtrausverse, 
  half 
  as 
  long 
  again 
  as 
  the 
  punctato- 
  

   rugulose 
  metazona, 
  cut 
  rather 
  deeply 
  in 
  the 
  middle 
  by 
  a 
  straight 
  trans- 
  

   verse 
  sulcus, 
  followed 
  at 
  less 
  than 
  half 
  the 
  distance 
  to 
  the 
  metazona 
  

   by 
  a 
  still 
  deeper, 
  scarcely 
  arcuate, 
  percurrent 
  sulcus, 
  from 
  which 
  there 
  

   runs 
  backward, 
  on 
  the 
  middle 
  of 
  either 
  side, 
  a 
  short 
  impressed 
  line. 
  

   Prosternal 
  spine 
  stout, 
  erect, 
  conical; 
  meso- 
  and 
  metastethia 
  together 
  

   distinctly 
  longer 
  than 
  broad 
  in 
  both 
  sexes, 
  rapidly 
  narrowing 
  behind, 
  

   so 
  that 
  the 
  portion 
  posterior 
  to 
  the 
  metasternal 
  lobes 
  is 
  only 
  about 
  half 
  

   the 
  greatest 
  width 
  of 
  the 
  metastethium; 
  interval 
  between 
  the 
  meso- 
  

   sternal 
  lobes 
  in 
  both 
  sexes 
  distinctly 
  transverse, 
  broader 
  than 
  tbe 
  lobes 
  

   themselves; 
  metasternal 
  lobes 
  rather 
  distant 
  (male) 
  or 
  distant 
  (female), 
  

   at 
  least 
  as 
  widely 
  separated 
  as 
  the 
  breadth 
  of 
  the 
  frontal 
  costa. 
  

   Tegmina 
  fully 
  developed 
  or 
  abbreviate, 
  their 
  inner 
  edges 
  in 
  neither
