  They

  the

  on

  they

  This 
  worm 
  may 
  at 
  

   once 
  be 
  distinguished 
  from 
  the 
  imported 
  currant-worm 
  by 
  the 
  absence 
  

   of 
  the 
  minute 
  black 
  warts 
  that 
  cover 
  the 
  body 
  of 
  the 
  latter. 
  The 
  same 
  

   remedies 
  should 
  be 
  used 
  for 
  this 
  worm 
  as 
  are 
  recommended 
  for 
  the 
  pre- 
  

   ceding 
  insect.

  Many 
  persons, 
  in 
  speaking 
  of 
  the 
  " 
  currant- 
  

   worm," 
  confound 
  the 
  caterpillar-like 
  saw-fly 
  larva 
  

   with 
  the 
  well-known 
  geometer 
  caterpillar, 
  which 
  

   is 
  a 
  native 
  species, 
  and 
  was 
  long 
  since 
  described 
  

   by 
  Dr. 
  Fitch, 
  under 
  the 
  name 
  of 
  Abraxas 
  rihea- 
  

   ria. 
  As 
  soon 
  as 
  the 
  leaves 
  of 
  the 
  currant 
  are 
  

   fairly 
  expanded, 
  late 
  in 
  May 
  or 
  early 
  in 
  June, 
  the 
  

   young 
  caterpillars, 
  scarcely 
  thicker 
  than 
  a 
  horse- 
  

   hair, 
  may 
  be 
  found 
  eating 
  little 
  holes 
  in 
  them.

   In 
  about 
  three 
  weeks 
  after 
  hatching 
  it 
  becomes 
  fully 
  grown, 
  being 
  

   about 
  an 
  inch 
  long, 
  and 
  bright-yellow 
  in 
  color, 
  the 
  body 
  being 
  covered 
  

   with 
  large, 
  black 
  dots. 
  The 
  chrys- 
  

   alis 
  is 
  shining 
  reddish-brown, 
  about 
  

   half 
  an 
  inch 
  long, 
  and 
  may 
  be 
  found 
  

   late 
  in 
  June, 
  either 
  upon 
  the 
  

   ground 
  or 
  just 
  under 
  the 
  surface. 
  

   In 
  two 
  weeks 
  after 
  entering 
  the 
  

   chrysalis 
  state 
  the 
  moth 
  may 
  be 
  

   observed 
  flying 
  about 
  the 
  garden 
  

   or 
  resting 
  upon 
  the 
  leaves 
  during 
  

   cloudy 
  weather. 
  The 
  moth 
  is 
  yel- 
  

   low 
  ochreous, 
  with 
  dark, 
  often 
  

   nearly 
  transparent, 
  blotches 
  on 
  the 
  

   wings. 
  It 
  is 
  not 
  easily 
  mistaken 
  

   for 
  any 
  other 
  moth.
