  This 
  species 
  differs 
  from 
  the 
  two 
  preceding 
  by 
  the 
  greater 
  roundness 
  of 
  

   the 
  sides 
  of 
  the 
  thorax, 
  which 
  is 
  slightly 
  wider 
  at 
  the 
  middle 
  than 
  at 
  the 
  base. 
  The 
  

   hairs 
  of 
  the 
  sides 
  are 
  shorter 
  and 
  fewer 
  in 
  number 
  ; 
  those 
  of 
  the 
  sides 
  of 
  the 
  elytra 
  are 
  

   about 
  as 
  usual.

  The 
  difference 
  in 
  color 
  would 
  tempt 
  

   many 
  to 
  separate 
  the 
  variety 
  with 
  fulvous 
  elytra, 
  but, 
  although 
  intermediate 
  speci- 
  

   mens 
  do 
  not 
  occur, 
  no 
  difference 
  in 
  form 
  or 
  sculpture 
  exists.

  Among 
  the 
  divisions 
  with 
  prominent 
  conical 
  anterior 
  coxte, 
  this 
  is 
  distinguished 
  

   by 
  the 
  upper 
  lip 
  being 
  small 
  and 
  beneath 
  the 
  prolonged 
  clypeus, 
  the 
  mentum 
  chan- 
  

   neled, 
  narrow, 
  the 
  segments 
  of 
  the 
  abdomen 
  not 
  connate, 
  the 
  fifth 
  always 
  longer 
  than 
  

   the 
  others, 
  and 
  finally 
  by 
  the 
  ungues 
  being 
  mostly 
  equal 
  and 
  diverging, 
  and 
  not 
  

   capable 
  of 
  being 
  folded 
  along 
  the 
  joint. 
  The 
  genera 
  are 
  numerous, 
  and 
  entirely 
  

   confined 
  to 
  America 
  ; 
  only 
  one 
  is 
  found 
  within 
  our 
  limits.

  New 
  York. 
  The 
  abdomen 
  of 
  the 
  female 
  is 
  black 
  and 
  entirely 
  free 
  from 
  bristles 
  ; 
  

   that 
  of 
  the 
  male 
  is 
  testaceous, 
  and 
  at 
  the 
  middle 
  of 
  each 
  segment 
  are 
  long 
  bristles, 
  

   without 
  order, 
  and 
  more 
  numerous 
  than 
  in 
  M. 
  elongatus. 
  Like 
  the 
  other 
  species 
  it 
  is 
  

   very 
  destructive 
  to 
  roses.
