  pale 
  red, 
  apically 
  infuscated. 
  The

  sur- 
  

   face 
  of 
  the 
  body 
  and 
  the 
  tegmina 
  are 
  more 
  or 
  less 
  profusely 
  dotted 
  with 
  

   very 
  pale 
  fuscous; 
  an 
  obli(iue, 
  cuneiform, 
  yellow 
  dash, 
  the 
  apex 
  in 
  front 
  

   and

  follows 
  the 
  ridge 
  of 
  the 
  nietathoracic 
  episterna, 
  margined 
  

   on 
  either 
  side 
  by 
  an 
  equal 
  piceous 
  belt. 
  The 
  hind

  generally 
  

   partake 
  of 
  the 
  color 
  of 
  the

  appear 
  darker 
  

   from 
  being 
  specked 
  with 
  blackish 
  fuscous 
  dots, 
  which 
  generally 
  cluster 
  

   more 
  or 
  less 
  into 
  two 
  very 
  oblique 
  bands 
  in 
  the

  PLEBEJUS 
  SEKIES. 
  

  

  In 
  this 
  somewhat 
  homogeneous 
  group, 
  the 
  prozona 
  is 
  distinctly 
  

   longitudinal 
  in 
  both 
  sexes 
  (the 
  female 
  of 
  one 
  species 
  is 
  not 
  known) 
  and 
  

   nearly 
  or 
  quite 
  half 
  as 
  long 
  again 
  as 
  the 
  metazona, 
  the 
  posterior 
  margin 
  

   of 
  which 
  is 
  subtruncate 
  or 
  truncate 
  or 
  soiuetimes 
  very 
  obtusangulate. 
  

   The 
  interspace 
  between 
  the 
  mesosternal 
  lobes 
  in 
  the 
  male 
  is 
  more 
  than 
  

   twice, 
  sometimes 
  thrice, 
  as 
  long 
  as 
  broad. 
  The 
  tegmina 
  are 
  very 
  vari- 
  

   able; 
  one 
  species 
  is 
  dimorphic, 
  having 
  either 
  fully 
  developed 
  tegmina 
  

   and 
  wings 
  considerably 
  surpassing 
  the 
  tips 
  of 
  the 
  hind 
  femora, 
  or 
  

   ovate 
  lanceolate 
  overlapping 
  tegmina, 
  acuminate 
  at 
  tip 
  and 
  a 
  little 
  

   longer 
  than 
  the 
  pronotum; 
  another 
  is 
  macropterous 
  with 
  subequal 
  

   tegmina, 
  reaching 
  the 
  tips 
  of 
  the 
  hind 
  femora; 
  the 
  other 
  species 
  are 
  

   l)rachypterous, 
  but 
  the 
  tegmina 
  are 
  variably 
  shaped. 
  — 
  sometimes 
  as 
  

   ill 
  the 
  brachypterous 
  form 
  of 
  the 
  dimorphic 
  species, 
  at 
  others 
  either 
  

   rounded 
  ovate 
  and 
  attingent, 
  or 
  widely 
  separated 
  and 
  lateral. 
  

  

  The 
  supraanal 
  plate 
  is 
  triangular, 
  Avitli 
  generally 
  a 
  tolerably 
  plane 
  

   surface; 
  the 
  furcula 
  is 
  obsolete, 
  subobsolete, 
  or 
  reduced 
  to 
  mere 
  brief 
  

   denticulations; 
  the 
  cerci 
  are 
  long, 
  constricted 
  in 
  the 
  middle, 
  but 
  

   ex]»anding 
  only 
  a 
  little 
  apically, 
  incurved, 
  and 
  bluntly 
  rounded 
  or 
  

   interiorly 
  subacuminate 
  at 
  tip; 
  the 
  subgenital 
  plate 
  is 
  always 
  small, 
  

   distinctly 
  narrower 
  than 
  long, 
  often 
  narrowing 
  ai)ically, 
  and 
  sometimes 
  

   ends 
  in 
  a 
  tubercle. 
  

  

  There 
  are 
  five 
  species, 
  most 
  of 
  tliem 
  widely 
  separated 
  from 
  one 
  

   another: 
  one 
  occurs 
  in 
  the 
  upper 
  Mississippi 
  valley 
  from 
  the 
  Dakotas 
  

   to 
  Kentucky', 
  while 
  the 
  others 
  are 
  found 
  respectively 
  in 
  Florida 
  (two 
  

   species), 
  Texas, 
  and 
  California.
