  I 
  have 
  also 
  seen 
  specimens 
  from 
  the 
  following 
  localities, 
  which 
  have 
  

   some 
  special 
  interest: 
  Fort 
  Hayes, 
  Kansas, 
  collected 
  by 
  J. 
  A. 
  Allen 
  in 
  

   June, 
  1871 
  (not 
  heretofore 
  reported 
  in 
  Kansas 
  in 
  this 
  year); 
  Preston, 
  

   Texas, 
  Captain 
  Poj)e, 
  May

  1854 
  (necessarily 
  the 
  progeny 
  of 
  an 
  invad- 
  

   ing 
  iiight 
  in 
  a 
  previous 
  year, 
  and 
  none 
  are 
  recorded 
  either 
  in 
  Texas 
  or 
  

   Arkansas 
  between 
  1850 
  and 
  1853, 
  inclusive); 
  Einggold 
  P)arracks, 
  on 
  

   the 
  Lower 
  Eio 
  Grande, 
  A. 
  Schott, 
  presumably 
  also 
  in 
  the 
  spring 
  of 
  

   1854, 
  when 
  the 
  Mexican 
  Boundary 
  Commission 
  was 
  at 
  work 
  there; 
  

   Sonora, 
  Mexico, 
  A. 
  Schott, 
  and 
  San 
  Lorenzo, 
  Chihuahua, 
  Mexico, 
  E. 
  

   Palmer, 
  showing 
  that 
  it 
  reaches 
  Mexico, 
  and 
  that 
  too 
  even 
  as 
  far 
  west 
  

   as 
  Sonora. 
  I 
  have 
  also 
  a 
  single 
  specimen 
  from 
  California 
  from 
  Mr. 
  H. 
  

   Edw^ards, 
  but 
  it 
  may 
  have 
  been 
  taken 
  in 
  that 
  part 
  of 
  the 
  State 
  east 
  of 
  

   the 
  Sierra 
  Nevada. 
  

  

  A

  This 
  insect 
  is 
  normally 
  single 
  brooded; 
  the 
  eggs 
  winter 
  and 
  the 
  

   earliest 
  (those 
  in 
  warm 
  exf)osures) 
  hatch 
  in 
  Texas 
  from 
  the 
  middle 
  to 
  

   the 
  last 
  of 
  3Iarch, 
  and 
  '' 
  continue 
  to 
  hatch 
  most 
  numerously 
  about 
  four 
  

   days 
  later 
  with 
  each 
  degree 
  of 
  latitude 
  north," 
  so 
  that 
  in 
  Montana 
  and 
  

   Manitoba 
  it 
  is 
  from 
  the 
  middle 
  of 
  3[ay 
  to 
  the 
  first 
  of 
  June. 
  This 
  is 
  in 
  

   the 
  temporary 
  region 
  ; 
  probably 
  it 
  is 
  correspondingly 
  later 
  on 
  the 
  higher 
  

   levels 
  of 
  the 
  permanent 
  breeding 
  grounds. 
  The 
  young 
  reach 
  maturity 
  

   in 
  sixty 
  to 
  seventy-two 
  days, 
  to 
  judge 
  from 
  those 
  reared 
  in 
  confine- 
  

   ment, 
  and 
  after 
  a 
  few 
  days 
  couple, 
  the 
  female 
  beginning 
  to 
  lay 
  eggs 
  in 
  

   about 
  a 
  fortnight 
  thereafter. 
  The 
  eggs 
  are 
  laid 
  in 
  almost 
  any 
  kind 
  of 
  

   soil, 
  but 
  by 
  preference 
  in 
  bare, 
  sandy 
  places, 
  and 
  in 
  their 
  permanent 
  

   home 
  they 
  show 
  a 
  preference 
  for 
  the 
  shaded 
  base 
  of 
  shrubby 
  plants; 
  

   they 
  are 
  laid 
  in 
  a 
  sort 
  of 
  pod, 
  with 
  a 
  quadrilinear 
  arrangement 
  therein. 
  

   Several 
  pods 
  may 
  be 
  laid 
  by 
  a 
  single 
  female, 
  Mr. 
  Eiley 
  having 
  on 
  

   three 
  different 
  occasions 
  obtained 
  two 
  pods 
  from 
  single 
  females 
  in 
  con- 
  

   finement, 
  laid 
  at 
  intervals 
  of 
  eighteen, 
  twenty-one, 
  and 
  twenty-six 
  days, 
  

   respectively. 
  

  

  The 
  migratory 
  instinct 
  appears 
  to 
  be 
  strongest 
  within 
  about 
  tliree 
  

   weeks 
  from 
  the 
  time 
  of 
  attaininii" 
  maturitv, 
  or 
  shortlv 
  before 
  and 
  during
