  as 
  long 
  as 
  

   broiul, 
  the

  broad 
  deep 
  sulcus,

  slight 
  median 
  longitudinal 
  sulcus 
  from 
  the 
  extrem- 
  

   ity 
  of 
  the 
  basal 
  ridge; 
  furcula 
  consisting 
  of

  subtrian- 
  

   gular 
  projections 
  overlying 
  the 
  two 
  bases 
  of 
  the 
  basal

  The 
  species 
  was 
  originally 
  described 
  from 
  Colorado, 
  Wyoming, 
  and 
  

   Kansas, 
  and 
  has 
  since 
  been 
  reported 
  from 
  [New 
  Jersey] 
  (Uhler), 
  [Min- 
  

   nesota] 
  and 
  Iowa 
  (Bruner), 
  Nebraska 
  (Thomas, 
  Bruner), 
  Kansas 
  and 
  

   Colorado 
  (Bruner), 
  Beaver 
  Brook 
  and

  Grand 
  Canyon 
  of

  Arkan- 
  

   sas 
  (Uhler); 
  Texas 
  [and 
  Mexico] 
  (Uhler); 
  [Utah] 
  (Bruner), 
  and 
  San 
  

   Joaquin 
  Valley, 
  California 
  (Coquillet). 
  Localities 
  which 
  are 
  in 
  doubt 
  

   or 
  in 
  error 
  are 
  placed 
  in 
  brackets. 
  

  

  This 
  species 
  closely 
  resembles 
  H. 
  festirusy 
  but 
  while 
  generally 
  of 
  a 
  

   little 
  larger 
  size 
  is 
  distinguished 
  from 
  it 
  by 
  the 
  black-marked 
  sulci 
  of 
  

   the 
  pronotum, 
  the 
  generally 
  but 
  not 
  invariably 
  greater 
  irregularity 
  of 
  

   the 
  markings 
  of 
  the 
  lateral 
  lobes 
  of 
  the 
  pronotum, 
  the 
  red 
  annulation 
  

   of 
  the 
  hind 
  femora 
  (though 
  this 
  will 
  probably 
  be 
  found 
  in 
  some 
  individ- 
  

   uals 
  of 
  H. 
  festivKs) 
  and 
  the 
  ground 
  color 
  of 
  the 
  head 
  and 
  iironotum, 
  as 
  

   well 
  as 
  in 
  slight 
  differences 
  in 
  the 
  abdominal 
  appendages 
  of 
  the 
  male. 
  

   The 
  eyes 
  are 
  slightly 
  more 
  elongate 
  in 
  H. 
  festivKS 
  than 
  in 
  the 
  present 
  

   species, 
  at 
  least 
  in 
  the 
  female. 
  

  

  It 
  is 
  Avholly 
  uncertain 
  to 
  what 
  species 
  belongs 
  the 
  reference 
  by 
  

   Thomas' 
  to 
  an 
  insect 
  with 
  tegmina 
  only 
  one-third 
  the 
  length 
  of 
  the 
  

   abdomen, 
  taken 
  in 
  northern 
  New 
  Mexico 
  or 
  Colorado. 
  I 
  have 
  placed 
  

   it 
  here 
  with 
  a 
  query.
