  It 
  meas- 
  

   ures, 
  when 
  extended, 
  three-tenths 
  of 
  an 
  inch 
  (8 
  mm.), 
  being 
  of 
  about 
  

  

  the 
  same 
  proportions 
  

   as 
  the 
  larva 
  of 
  the 
  

   common 
  species, 
  but 
  is 
  

   readily 
  separable 
  by 
  its 
  

   ochraceous 
  orange 
  

   color. 
  The 
  ground 
  

   color 
  is 
  light 
  yellowish 
  

   cream 
  with 
  an 
  overlay 
  

   of 
  ochraceous 
  orange

  the

  the 
  

   abdominal 
  segments. 
  

   The 
  head, 
  with 
  the 
  exception 
  of 
  the 
  mouth-parts, 
  is 
  also 
  ochraceous, 
  

   the 
  thoracic 
  plate 
  is 
  prominent, 
  divided

  is 
  of 
  a

   brown 
  color.

  Life-History 
  and 
  Habits. 
  

  

  Comparatively 
  little 
  is 
  known 
  of 
  the 
  life-history 
  of 
  this 
  species. 
  Two 
  

   annual 
  broods 
  are 
  ascribed 
  to 
  it 
  in 
  Europe, 
  while 
  there 
  are 
  presumably 
  

   three 
  in 
  this 
  country, 
  especially 
  in 
  the 
  southern 
  portions. 
  The 
  eggs 
  

   are 
  not 
  known, 
  although 
  it 
  has 
  been 
  suggested 
  that 
  they 
  may 
  be 
  

   deposited, 
  like 
  those 
  of 
  C. 
  asparagi, 
  on 
  the 
  leaves 
  and 
  stems. 
  But 
  few 
  

   larvae 
  have 
  been 
  observed. 
  One 
  was 
  found 
  on 
  the 
  foliage 
  and 
  others 
  in 
  

   various 
  stages, 
  were 
  feeding 
  in 
  the 
  berries. 
  The 
  infested 
  fruit 
  reddens 
  

   prematurely, 
  is 
  reduced 
  to 
  pulp, 
  and 
  the 
  larvae, 
  on 
  completing 
  their 
  

   growth, 
  enter 
  the 
  ground 
  for 
  pupation. 
  The 
  food 
  of 
  the 
  earlier 
  

   brood 
  appears 
  unknown, 
  unless 
  it 
  be 
  the 
  foHage, 
  as 
  with 
  the 
  common 
  

   species. 
  In 
  the 
  latter 
  part 
  of 
  the 
  season 
  the 
  berries 
  are 
  preferred 
  by 
  the 
  

   larvae. 
  In 
  Europe, 
  the 
  insect 
  is 
  said 
  to 
  pass 
  the 
  winter 
  in 
  the 
  pupa 
  state, 
  

   but 
  in 
  this 
  country 
  some, 
  judging 
  by 
  analogy, 
  are 
  of 
  the 
  opinion 
  that 
  it 
  

   more 
  probably 
  hibernates 
  in 
  the 
  adult 
  form. 
  Pupation 
  occupies 
  about 
  

   two 
  or 
  three 
  weeks 
  during 
  the 
  summer 
  and 
  if 
  the 
  insects 
  hibernate 
  as 
  

   beetles, 
  the 
  pupation 
  of 
  the 
  later 
  brood 
  would 
  probably 
  occupy 
  but 
  little 
  

   longer. 
  

  

  The 
  few 
  beetles 
  observed 
  by 
  Mr. 
  Robbins 
  in 
  early 
  May 
  were 
  most 
  

   likely 
  the 
  last 
  of 
  the 
  overwintered 
  beetles 
  or, 
  if 
  hibernating 
  as 
  pupae,
