  One 
  of 
  the 
  smallest 
  if 
  not 
  the 
  very 
  smallest 
  macropterous 
  species 
  of 
  

   Melanoplus 
  known. 
  The 
  general 
  color 
  is 
  a 
  dark 
  griseous, 
  the 
  vertex 
  

   of 
  the 
  head 
  marked 
  in 
  black 
  and 
  dull 
  yellow 
  in 
  a 
  somewhat 
  radiate 
  

   fashion, 
  the 
  whole 
  face 
  and 
  sides 
  of 
  head 
  brownish 
  olive 
  or 
  sordid 
  

   yellow, 
  flecked 
  more 
  or 
  less 
  abundantly 
  with 
  black; 
  the 
  antennae 
  are 
  

   pale 
  dirty 
  yellow, 
  becoming 
  infuscated 
  toward 
  the 
  tip; 
  behind 
  the 
  eye 
  

   is 
  a 
  broad 
  black 
  band, 
  often 
  edged 
  with 
  yellow 
  above, 
  which 
  also 
  

   traverses 
  the 
  upper 
  half 
  or 
  less 
  of 
  the 
  lateral 
  lobes, 
  confined 
  to 
  the 
  

   prozona, 
  and 
  is 
  often 
  enlivened 
  by 
  a 
  small 
  pale 
  quadrate 
  patch 
  in 
  the 
  

   center 
  of 
  the 
  lobes; 
  the 
  rest 
  of 
  the 
  latter 
  varies 
  from 
  yellow 
  to 
  brown, 
  

   palest 
  next 
  the 
  margins; 
  the 
  upper 
  surface 
  of 
  the 
  pronotuin 
  varies 
  a 
  

   good 
  deal, 
  but 
  is 
  usually 
  griseous, 
  often 
  with 
  a 
  median 
  belt 
  of 
  dirty 
  

   yellow 
  or 
  ferruginous, 
  edged 
  on 
  the 
  front 
  of 
  the 
  metazona 
  by 
  a 
  pair 
  of 
  

   oblique, 
  crescentic, 
  longitudinal 
  or 
  converging 
  patches 
  of 
  black. 
  Teg- 
  

   mina 
  cinereous, 
  with 
  alternate 
  minute 
  blocks 
  of 
  yellow 
  and 
  blackish 
  

   fuscous 
  in 
  the 
  discoidal 
  area, 
  apically 
  changing 
  to 
  scattered 
  quadrate 
  

   fuscous 
  dots. 
  Hind 
  femora 
  below 
  straw-yellow, 
  above 
  dark 
  brown, 
  

   with 
  a 
  i)air 
  of 
  conspicuous, 
  very 
  oblique 
  pale 
  bars 
  at 
  the 
  middle 
  and 
  

   next 
  the 
  base; 
  hind 
  tibiae 
  pale 
  glaucous, 
  occasionally 
  with 
  a 
  faint 
  

   rufous 
  tinge, 
  becoming 
  paler 
  next 
  the 
  base 
  and 
  straw-yellow 
  at 
  the 
  tip, 
  

   the 
  siDines 
  more 
  or 
  less 
  heavily 
  black-tipped, 
  ten 
  to 
  eleven, 
  rarely 
  

   twelve, 
  in 
  number 
  in 
  the 
  outer 
  series; 
  hind 
  tarsi 
  yellowish. 
  

  

  Head 
  rather 
  large, 
  but 
  not 
  elevated, 
  and 
  moderately 
  arched; 
  inter- 
  

   space 
  between 
  the 
  eyes 
  scarcely 
  broader 
  than 
  the 
  first 
  antennal 
  joint 
  

   (male) 
  or 
  broader 
  than 
  the 
  length 
  of 
  the 
  same 
  (female); 
  fastigium 
  

   steeply 
  decliveut, 
  deeply 
  and 
  roundly 
  (male) 
  or 
  shallowly 
  and 
  flatly 
  

   (female) 
  sulcate, 
  the 
  lateral 
  margins 
  blunt 
  and 
  either 
  slightly 
  (female) 
  

   or 
  distinctly 
  (male) 
  divergent 
  and 
  then 
  anteriorly 
  convergent; 
  frontal 
  

   cojta 
  broad, 
  nearly 
  equal, 
  slightly 
  broader 
  below 
  than 
  above, 
  tumid 
  

   (female) 
  or 
  flat 
  (male) 
  above, 
  with 
  a 
  row 
  of 
  puncta 
  on 
  either 
  side, 
  

   narrowly 
  and 
  rather 
  slightly 
  sulcate 
  at 
  and 
  just 
  below 
  the 
  ocellus; 
  

   eyes 
  rather 
  large, 
  moderately 
  prominent, 
  a 
  little 
  longer 
  than 
  (male) 
  

   or 
  about 
  as 
  long 
  as 
  (female) 
  the 
  infraocular 
  portion 
  of 
  the 
  genae;
