  In 
  details 
  of 
  structure 
  this 
  species 
  closely 
  resembles 
  Ae. 
  arizonensis, 
  

   but 
  is 
  remarkable 
  for 
  its 
  compressed 
  form 
  and 
  its 
  large 
  and 
  prominent 
  

   eyes, 
  in 
  which 
  points 
  it 
  exceeds 
  even 
  that 
  species.

  Body 
  stout, 
  comi>act, 
  heavy, 
  generally, 
  and 
  especially 
  in 
  the 
  female, 
  

   very 
  broad 
  at 
  the 
  metathorax. 
  Head 
  stout, 
  slightly 
  broader 
  below 
  

   than 
  above, 
  the 
  genae 
  full; 
  eyes 
  separated 
  by 
  a 
  wide 
  space, 
  wider 
  and 
  

   generally 
  much 
  wider 
  than 
  the 
  broad 
  frontal 
  costa; 
  front 
  well 
  rounded, 
  

   vertical, 
  the 
  frontal 
  costa 
  pr(miiiu^nt, 
  broad, 
  and 
  generally 
  somewhat 
  

   sulcate, 
  at 
  least 
  above; 
  antennae 
  slender 
  for 
  such 
  bulky 
  insects, 
  equal, 
  

   shorter 
  and 
  generally 
  mu(!h 
  shorter 
  than 
  the 
  hind 
  femora. 
  Thorax 
  very 
  

   stout, 
  the 
  pronotum 
  very 
  short, 
  not 
  covering 
  the 
  whole 
  of 
  the 
  meso- 
  

   notum, 
  truncate 
  at 
  either 
  extremity, 
  the 
  metazona 
  only 
  about 
  half 
  as 
  

   long 
  as 
  the 
  prozona 
  and 
  rugulose, 
  M'hile 
  tlieprozona 
  is 
  smooth; 
  lateral 
  

   lobes 
  sometimes 
  separated 
  from 
  tlie 
  dorsum 
  by 
  distinct 
  rugae. 
  Pro- 
  

   sternal 
  spine 
  very 
  much 
  abbreviated, 
  becoming 
  in 
  the 
  female 
  a 
  mere 
  

   blunt 
  tubercle, 
  and 
  in 
  the 
  male 
  very 
  short 
  and 
  conical; 
  mesostethium 
  

   and 
  metastethium 
  together, 
  in 
  both 
  sexes, 
  but 
  particularly 
  in 
  the 
  female, 
  

   no 
  longer 
  or 
  scarcely 
  longer 
  than 
  broad; 
  the 
  interspace 
  between 
  the 
  

   mesosternal 
  lobes 
  wide 
  in 
  both 
  sexes, 
  but 
  showing 
  a 
  remarkable 
  degree 
  

   of 
  variation 
  quite 
  unknown 
  in 
  any 
  other 
  of 
  the 
  genera 
  of 
  Melanopli; 
  

   the 
  metasternal 
  lobes 
  distant, 
  sometimes 
  very 
  distant, 
  in 
  the 
  female, 
  

   approximate 
  or 
  moderately 
  distant 
  in 
  the 
  male.

  and 
  wings 
  

   altogether 
  wanting. 
  Fore 
  and 
  middle

  of 
  male 
  tumid; 
  hind 
  

   femora 
  (excepting 
  in 
  B. 
  hlspida) 
  rather 
  short, 
  moderately 
  stout, 
  reach- 
  

   ing 
  beyond 
  the 
  abdomen 
  in 
  the 
  male, 
  but 
  generally 
  not 
  in 
  the 
  female, 
  

   the 
  upper 
  carina 
  smooth. 
  Terminal 
  abdominal 
  joints 
  of 
  the 
  female 
  

   short, 
  with 
  slightly 
  exserted 
  ovij)ositor, 
  making 
  the 
  tip 
  blunt, 
  as 
  in 
  

   Oedalconotus 
  aiul 
  Aeolojjlus, 
  bnt 
  perhaps 
  to 
  a 
  greater 
  degree;

   men 
  of 
  male 
  apically 
  clavate, 
  upturned, 
  the 
  subgenital 
  plate 
  long 
  and 
  

   tumid, 
  without 
  apical 
  tubercle; 
  furcula 
  absent 
  or 
  (in 
  one 
  species) 
  rep- 
  

   resented 
  by 
  feeble 
  lobes: 
  cerci 
  simple, 
  conical, 
  straight.

  This 
  somewhat 
  remarkable 
  genns 
  is, 
  so 
  far 
  as 
  known, 
  confined 
  to 
  the 
  

   extreme 
  northwestern 
  United 
  States, 
  but 
  will 
  probably 
  be 
  found 
  also 
  

   in 
  British 
  Columbia. 
  It 
  extends 
  from 
  the 
  Pacific 
  to 
  JNfontaua 
  and 
  

   Wyoming, 
  and 
  has 
  so 
  far 
  been 
  reported 
  only 
  north 
  of 
  the 
  latitude 
  of
