﻿REPORT 
  OF 
  THE 
  STATE 
  ENTOMOLOGIST

  It 
  will 
  here 
  be 
  opportune 
  to 
  refer 
  to 
  the 
  attempt 
  by 
  Dr. 
  Riley 
  to 
  deter- 
  

   mine 
  by 
  experiment, 
  whether 
  these 
  two 
  broods 
  were 
  really 
  distinct 
  species 
  

   or 
  only 
  races. 
  In 
  1885, 
  eggs 
  of 
  the 
  thirteen-year 
  brood 
  were 
  sent 
  to 
  

   several 
  places 
  in 
  the 
  Northern 
  States, 
  and 
  similar 
  transfers 
  of 
  the 
  eggs 
  of 
  

   the 
  seventeen-year 
  brood 
  were 
  made 
  to 
  the 
  Southern 
  States. 
  The 
  object 
  

   of 
  the 
  transfer 
  was 
  to 
  test 
  the 
  question 
  whether 
  the 
  change 
  from 
  a 
  warm 
  

   latitude 
  to 
  a 
  colder, 
  and 
  vice 
  versa, 
  would 
  have 
  any 
  marked 
  effect 
  in 
  

   retarding 
  or 
  hastening 
  the 
  life-period 
  of 
  the 
  insect. 
  Two 
  lots 
  of 
  eggs 
  of 
  

   the 
  thirteen-year 
  brood 
  were 
  received 
  by 
  me 
  in 
  July 
  from 
  Dr. 
  Riley 
  and 
  

   were 
  placed 
  in 
  the 
  apple 
  orchard 
  of 
  Mr. 
  Erastus 
  Corning, 
  at 
  Kenwood, 
  

   near 
  Albany. 
  The 
  tree 
  under 
  which 
  they 
  were 
  placed 
  bears 
  the 
  follow- 
  

   ing 
  inscription 
  on

  label:

  TMrteefi-year

  J 
  — 
  eggs 
  from 
  

   Oxford, 
  Mississippi, 
  planted 
  July 
  4, 
  1885." 
  

  

  Additional 
  eggs, 
  together 
  with 
  the 
  larvae 
  that 
  had 
  hatched 
  while 
  in 
  

   transit, 
  were 
  placed 
  under 
  the 
  same 
  tree 
  July 
  21. 
  If 
  any 
  of 
  the 
  insects 
  

   have 
  lived 
  and 
  remain 
  true 
  to 
  their 
  period, 
  their 
  appearance 
  may 
  be 
  

   expected 
  in 
  May 
  or 
  June, 
  1898. 
  Should 
  they 
  fail 
  to 
  appear 
  at 
  that 
  time, 
  

   search 
  will 
  be 
  made 
  for 
  them, 
  if 
  need 
  be, 
  for 
  two 
  or 
  three 
  successive 
  years, 
  

   and 
  the 
  results 
  reported 
  to 
  the 
  Entomological 
  Division 
  of 
  the 
  Depart- 
  

   ment 
  of 
  Agriculture 
  at 
  Washington. 
  Eggs 
  of 
  this 
  same 
  brood 
  were 
  also 
  

   sent 
  by 
  Dr. 
  Eiley, 
  to 
  Ithaca, 
  N. 
  Y.; 
  Boston, 
  Mass.; 
  Kittery 
  Point 
  and 
  

   Erunswick, 
  Me., 
  and 
  Ames, 
  Iowa. 
  

  

  Distribution 
  of 
  the 
  Hudson 
  River 
  Valley 
  Brood. 
  

  

  Dr. 
  Fitch, 
  in 
  1856, 
  gives 
  as 
  the 
  limits 
  of 
  this 
  brood, 
  the 
  valley 
  of 
  the 
  

   Hudson 
  river, 
  from 
  the 
  vicinity 
  of 
  Schuylerville 
  and 
  Fort 
  Miller* 
  on 
  the 
  

   north, 
  southward 
  along 
  both 
  sides 
  of 
  the 
  Hudson 
  to 
  its 
  mouth, 
  where 
  

   it 
  extends 
  northeastwardly, 
  at 
  least 
  to 
  New 
  Haven 
  in 
  Connecticut, 
  and 
  

   southward 
  across 
  the 
  northern 
  part 
  of 
  New 
  Jersey 
  and 
  into 
  Pennsylvania. 
  

   Later 
  observations 
  enabled 
  Dr. 
  Riley 
  to 
  extend 
  the 
  limits 
  of 
  this 
  brood, 
  — 
  

   including 
  the 
  greater 
  part 
  of 
  the 
  State 
  of 
  New 
  Jersey 
  most 
  probably; 
  

   localities 
  in 
  Fairfax, 
  Albemarle, 
  Campbell, 
  and 
  Fulvanna 
  counties, 
  Vir- 
  

   ginia; 
  Charles 
  county, 
  Maryland, 
  and 
  the 
  District 
  of 
  Columbia. 
  

  

  Observations 
  and 
  reports 
  upon 
  the 
  occurrence 
  of 
  this 
  brood 
  in 
  1894 
  

   enable 
  us 
  to 
  give 
  the 
  following 
  as 
  its 
  distribution 
  so 
  far 
  as 
  known: 
  

  

  In 
  New 
  York 
  the 
  brood 
  was 
  reported 
  from 
  the 
  Rural 
  cemetery 
  

   four 
  miles 
  north 
  of 
  Albany, 
  and 
  thence 
  southward 
  in 
  localities 
  

   ■on 
  both 
  sides 
  of 
  the 
  Hudson 
  river 
  to 
  New 
  York 
  City; 
  at 
  New 
  Brighton, 
  

  

  * 
  Forty-seven 
  miles 
  north 
  of 
  Albany.
