  One 
  male 
  found 
  at 
  New 
  York. 
  This 
  species 
  bears 
  no 
  resemblance 
  to 
  Say's 
  Melo- 
  

   lontha 
  longitarsis, 
  but 
  is 
  very 
  closely 
  allied 
  to 
  the 
  preceding, 
  from 
  which 
  it 
  differs 
  

   chiefly 
  by 
  the 
  clypeus 
  being 
  sparsely 
  punctured 
  and 
  more 
  deeply 
  emarginate, 
  and 
  by 
  

   the 
  body 
  being 
  more 
  slender. 
  

  

  Tbe 
  male 
  has 
  the 
  club 
  of 
  the 
  antennae 
  shorter 
  than 
  the 
  stem 
  ; 
  and 
  the 
  abdomen 
  and 
  

   posterior 
  tibia) 
  precisely 
  as 
  in 
  the 
  preceding 
  species.

  This 
  species 
  has 
  precisely 
  the 
  form 
  of 
  the 
  preceding, 
  but 
  the 
  head 
  is 
  

   more 
  coarsely 
  and 
  less 
  densely 
  punctured. 
  

  

  The 
  male 
  has 
  the 
  club 
  of 
  the 
  antenna? 
  longer 
  than 
  the 
  stem 
  ; 
  the 
  abdomen 
  faintly 
  

   channeled, 
  the 
  penultimate 
  segment 
  faintly 
  impressed 
  and 
  roughened 
  at 
  the 
  middle, 
  

   with 
  the 
  posterior 
  margin 
  not 
  emarginate 
  as 
  in 
  the 
  two 
  preceding, 
  with 
  a 
  very 
  

   slight 
  oblique 
  discoidal 
  elevation 
  each 
  side 
  towards 
  the 
  middle 
  ; 
  last 
  segment 
  with 
  a 
  

   very 
  deep 
  round 
  fovea, 
  bounded 
  each 
  side 
  by 
  an 
  elevated 
  ridge, 
  which, 
  however, 
  

   hardly 
  rises 
  into 
  a 
  cusp, 
  as 
  in 
  L. 
  cerasina. 
  Posterior 
  tibia? 
  with 
  the 
  terminal 
  

   fringe 
  of 
  spines 
  longer 
  than 
  usual, 
  with 
  the 
  inner 
  spur 
  distinct, 
  but 
  not 
  larger 
  than 
  

   one 
  of 
  the 
  spines 
  ; 
  outer 
  one 
  long, 
  slender. 
  

  

  A 
  female 
  which 
  I 
  refer 
  to 
  this 
  species 
  has 
  the 
  head 
  much 
  smaller, 
  being 
  only 
  two- 
  

   thirds 
  the 
  breadth 
  of 
  the 
  thorax, 
  the 
  eyes 
  small 
  and 
  distant, 
  and 
  the 
  spurs 
  of 
  the 
  

   posterior 
  tibia? 
  long 
  and 
  nearly 
  equal.

  One 
  female, 
  New 
  York, 
  Mr. 
  Guex. 
  Much 
  smaller 
  than 
  the 
  preceding, 
  but 
  similar 
  

   to 
  it 
  in 
  characters 
  ; 
  nevertheless, 
  the 
  clypeus 
  and 
  thorax 
  and 
  elytra 
  are 
  more 
  punc- 
  

   tured, 
  the 
  scutellum 
  is 
  strongly 
  punctured, 
  and 
  the 
  elytra 
  are 
  not 
  costate, 
  even 
  near 
  

   the 
  margin. 
  Tbe 
  pygidium 
  is 
  subtriangular, 
  shining 
  and 
  sparsely 
  punctured. 
  The 
  

   breast 
  is 
  very 
  slightly 
  pubescent, 
  and 
  the 
  claws 
  are 
  armed 
  with 
  a 
  small 
  tooth 
  at 
  the
