  integer 
  is 
  yellowish 
  red, 
  that 
  of 
  the 
  female 
  is 
  broadly 
  banded 
  with 
  the 
  

  

  same 
  color. 
  The 
  Tenthredo 
  is 
  also 
  a 
  stouter 
  insect 
  than 
  the 
  currant 
  stem 
  

  

  girdler. 
  In 
  length 
  it 
  measures 
  about 
  y%- 
  inch, 
  and 
  its 
  wing-spread 
  is 
  

  

  twice 
  its 
  length. 
  The 
  coxae 
  and 
  femora 
  of 
  the 
  anterior 
  two 
  pairs 
  of 
  legs 
  

  

  are 
  tipped 
  with 
  black, 
  and 
  the 
  apical 
  half 
  of 
  the 
  posterior 
  tibiae 
  and 
  their 
  

  

  tarsi 
  are 
  black. 
  The 
  other 
  characters 
  of 
  this 
  insect 
  may 
  be 
  recognized 
  

  

  by 
  the 
  accompanying 
  figure 
  (plate 
  i, 
  fig. 
  i). 
  

  

  The 
  following 
  is 
  Mr 
  Norton's 
  description 
  of 
  the 
  insect: 
  

  

  Female. 
  Black, 
  body 
  not 
  very 
  stout; 
  antennae 
  long 
  and 
  slender; 
  

   color

  tips 
  of 
  joints

   joints; 
  labrum 
  rounded 
  ;

   collar, 
  and 
  four 
  radiating

  a 
  white 
  

   spot 
  above 
  base 
  of

  legs 
  orange 
  red; 
  the 
  four 
  

   anterior

  Male. 
  The 
  male 
  has 
  a 
  yellow 
  spot 
  on 
  each 
  side 
  of 
  the 
  disk 
  of 
  clypeus 
  

   and 
  on 
  the 
  pleura 
  over 
  each 
  of 
  the 
  four 
  hinder 
  coxae; 
  the 
  first 
  and 
  second 
  

   segments 
  of 
  abdomen 
  and 
  the 
  basal

  Life 
  history 
  and 
  habits. 
  Very 
  little 
  is 
  known 
  of 
  the 
  life 
  history 
  

   and 
  habits 
  of 
  this 
  insect, 
  as 
  its 
  operations 
  in 
  the 
  currant 
  stems 
  at 
  the 
  

   same 
  time 
  as 
  those 
  of 
  Janus 
  i7iteger 
  has 
  led 
  to 
  the 
  ascribing 
  of 
  all 
  the 
  

   injury 
  to 
  that 
  species. 
  The 
  perfect 
  insects 
  were 
  observed 
  on 
  the 
  cur- 
  

   rant 
  stems 
  at 
  the 
  same 
  time 
  as 
  were 
  those 
  of 
  J. 
  mteger 
  by 
  Mr 
  Tupper, 
  

   but 
  their 
  oviposition 
  had 
  not 
  been 
  noticed 
  by 
  him. 
  The 
  stems 
  are 
  

   probably 
  injured 
  seriously 
  by 
  this 
  insect 
  while 
  ovipositing, 
  since 
  the 
  

   attack 
  is 
  revealed 
  by 
  the 
  wilted 
  tips 
  as 
  in 
  the 
  case 
  of 
  the 
  James. 
  There 
  

   is 
  apparently 
  but 
  a 
  single 
  brood 
  each 
  year, 
  as 
  the 
  imagoes 
  have 
  been 
  

   taken 
  in 
  May 
  at 
  Corning, 
  N. 
  Y., 
  and 
  in 
  June 
  and 
  early 
  in 
  July 
  at 
  

   Ottawa, 
  Canada. 
  

  

  Distribution. 
  This 
  species 
  is 
  probably 
  widely 
  distributed 
  over 
  the 
  

   northern 
  United 
  States. 
  Its 
  recorded 
  distribution 
  is 
  as 
  follows 
  : 
  New 
  

   England, 
  New 
  York, 
  New 
  Jersey, 
  Pennsylvania, 
  Illinois, 
  Iowa 
  and 
  

   Ottawa, 
  Canada. 
  There 
  appears 
  to 
  be 
  no 
  record 
  of 
  it 
  in 
  the 
  western 
  

   states, 
  although 
  it 
  will 
  probably 
  be 
  found 
  there 
  later. 
  

  

  Remedy. 
  The 
  wilted 
  tips 
  should 
  be 
  watched 
  for 
  in 
  the 
  early 
  spring, 
  

   and 
  as 
  soon 
  as 
  seen 
  should 
  be 
  cut 
  off 
  a 
  little 
  below 
  the 
  place 
  of 
  injury. 
  

   If 
  the 
  attack 
  should 
  escape 
  attention 
  till 
  sometime 
  after 
  the 
  dropping 
  of 
  

   the 
  tips, 
  the 
  cutting 
  should 
  be 
  made 
  a 
  few 
  inches 
  farther 
  down, 
  and 
  

   beyond 
  the 
  burrow 
  of 
  the 
  larva.
