  Morrison

  Packard 
  botli 
  say 
  that 
  it 
  is 
  much 
  less 
  common 
  than 
  ver- 
  

   nata 
  [in 
  Massachusetts]. 
  Bethune,^^ 
  "probably 
  referring 
  to 
  this 
  species^ 
  

   says 
  that 
  it 
  is 
  not 
  often 
  met 
  with 
  in 
  Canada^ 
  the 
  only 
  native 
  specimens 
  

   he 
  had 
  seen 
  having 
  been 
  found, 
  by 
  Mr. 
  Johnson 
  Pettit, 
  at 
  Grimsby, 
  

   Ontario, 
  during 
  November, 
  1866, 
  and 
  the 
  following 
  winter.^^ 
  Eeferringj, 
  

   evidently, 
  to 
  the 
  same 
  species,

  says, 
  in 
  1875,^'^ 
  that 
  the 
  Can-

  Worms 
  "■ 
  are 
  now 
  becoming 
  plentiful 
  in 
  portions 
  of 
  Ontario,

  CHARACTERS. 
  

  

  Under 
  critical 
  examination 
  the 
  Fall 
  Canker 
  Worm 
  is 
  readily 
  distin- 
  

   guished 
  from 
  the 
  Spring 
  species. 
  On 
  the 
  average 
  the 
  imago 
  is 
  some- 
  

   what 
  larger 
  and 
  more 
  glossy; 
  the 
  fore 
  wings 
  are 
  a 
  little 
  more 
  elongated 
  

   toward 
  the 
  apex, 
  making 
  the 
  outer 
  edge 
  a 
  little 
  longer 
  and 
  more 
  ob- 
  

   lique 
  ; 
  they 
  are 
  of 
  a 
  peculiar 
  ochreous-brown 
  tint, 
  as 
  in 
  the 
  European 
  

   wscularia; 
  they 
  have 
  a 
  distinct 
  white 
  spot 
  on 
  the 
  front 
  edge, 
  and 
  are 
  

   crossed 
  by 
  two 
  pale, 
  jagged 
  bands, 
  along, 
  the 
  sides 
  of 
  which 
  are 
  several 
  

   blackish 
  dots. 
  

  

  The 
  hind 
  wings 
  have 
  a 
  more 
  or 
  less 
  distinct, 
  pale, 
  curved 
  line 
  across 
  

   their 
  middle. 
  The 
  female 
  is 
  uniformly 
  dark 
  ash-gray 
  above, 
  paler 
  be- 
  

   neath, 
  and 
  with 
  naked 
  antennae 
  ; 
  her 
  legs 
  and 
  abdomen 
  are 
  smooth 
  

   and 
  glistening, 
  and 
  she 
  has 
  no 
  extensile 
  ovipositor. 
  

  

  Thus 
  these 
  images 
  lack 
  the 
  characteristic 
  dorsal 
  spines 
  of 
  vernatay 
  

   the 
  dusky 
  marks 
  across 
  the 
  front 
  wings 
  of 
  the 
  male, 
  and 
  the 
  pubes- 
  

   cence 
  in 
  the 
  female 
  ; 
  and 
  there 
  are 
  many 
  other 
  minor 
  differences, 
  which 
  

   are 
  mentioned 
  in 
  detail 
  in 
  the 
  tabular 
  and 
  comxjarative 
  description 
  al- 
  

   ready 
  given 
  of 
  the 
  two 
  insects. 
  

  

  We 
  give 
  the 
  following 
  detailed 
  descriptions 
  from 
  the 
  Seventh 
  En- 
  

   tomological 
  Report 
  of 
  Missouri.

  Length, 
  0.025 
  inch; 
  average 
  diameter 
  

   two-thirds 
  the 
  length 
  ; 
  flattened 
  at 
  top 
  where 
  it 
  is 
  somewhat 
  larger 
  than 
  at 
  base. 
  

   Color 
  of 
  crown 
  purplish-gray, 
  the 
  surface 
  slightly 
  corrugated, 
  with 
  a 
  central

   and 
  a 
  brown 
  circle 
  just 
  within 
  the 
  border 
  ; 
  sides 
  smooth 
  and 
  more 
  silvery, 
  and 
  gener- 
  

   ally 
  somewhat 
  compressed 
  by 
  pressure 
  of 
  adjacent 
  eggs. 
  Laid 
  in 
  exposed 
  situations, 
  

   in 
  patches 
  or 
  strips, 
  attached 
  in 
  regular 
  rows, 
  and 
  fastened 
  to 
  the 
  bark 
  in 
  a 
  slightly 
  

   slanting 
  position 
  so 
  that 
  one 
  edge 
  of 
  the 
  crown 
  is 
  a 
  little 
  above, 
  the 
  other 
  a 
  little 
  

   below 
  the 
  general 
  level. 
  

  

  Larva

  Color 
  pale-brownish, 
  marked 
  with 
  dark 
  brown 
  and 
  yellow

  follows 
  : 
  The 
  

   dorsum 
  uniformly 
  dark 
  brown 
  ; 
  the 
  sides 
  with 
  three 
  pale 
  narrow 
  lines, 
  more 
  or 
  les» 
  

   irregular 
  and 
  mottled, 
  but 
  always 
  well 
  relieved, 
  the 
  two 
  superior 
  ones 
  white, 
  the 
  

   lowermost 
  yellowish 
  ; 
  the 
  subdorsal 
  space 
  between 
  the 
  upper 
  two 
  of 
  these 
  lines, 
  pale^ 
  

   the 
  stigmatal 
  between 
  the 
  lower 
  two 
  darker, 
  especially 
  in 
  middle 
  of 
  the 
  joint 
  around 
  

   stigmata; 
  the 
  thoracic 
  joints 
  dark 
  with 
  the 
  pale 
  lines 
  somewhat 
  narrower

   ning

  On

  are 
  constricted 
  or 
  entirely 
  broken, 
  so 
  as 
  

   to

  a 
  dark 
  band 
  across 
  the 
  middle 
  of 
  the 
  joint. 
  The
