  The 
  males 
  are 
  more 
  slender 
  in 
  form 
  than 
  the 
  females, 
  and 
  are 
  distinguished 
  by 
  

   the 
  club 
  of 
  the 
  antennce 
  being 
  as 
  long 
  as 
  the 
  funiculus.

  Pennsylvania, 
  New 
  York, 
  Massachusetts, 
  Michigan 
  and 
  Lake 
  Superior. 
  Very 
  

   abundant 
  whenever 
  found. 
  Varies 
  in 
  color, 
  the 
  head 
  and 
  thorax 
  being 
  sometimes 
  

   almost 
  rufous 
  ; 
  the 
  elytra 
  are 
  uniformly 
  bronzed, 
  the 
  suture 
  and 
  a 
  narrow 
  margin 
  only 
  

   being 
  pale. 
  The 
  lateral 
  angles 
  of 
  the 
  thorax 
  are 
  rounded, 
  and 
  the 
  scutel 
  is 
  pubescent. 
  

   The 
  legs 
  are 
  yellow 
  ; 
  the 
  tarsi 
  and 
  posterior 
  tibiae 
  are 
  more 
  or 
  less 
  tinged 
  with 
  black-

  I 
  have 
  placed 
  a 
  query 
  to 
  the 
  synonym 
  of 
  Kirby, 
  as 
  his 
  var. 
  C. 
  (which 
  he 
  sup- 
  

   poses 
  may 
  be 
  different 
  from 
  the 
  type) 
  evidently 
  belongs 
  to 
  the 
  next 
  species, 
  which 
  

   from 
  want 
  of 
  attention 
  to 
  the 
  form 
  of 
  the 
  thorax 
  (a 
  character 
  that 
  has 
  been 
  omitted 
  

   by 
  previous 
  authors) 
  may 
  be 
  readily 
  confounded 
  with 
  the 
  present.

  Lake 
  Superior, 
  abundant. 
  The 
  scutel 
  is 
  densely 
  pubescent. 
  The 
  green 
  vitta 
  of 
  

   the 
  elytra 
  is 
  broad 
  and 
  curves 
  around 
  the 
  tip 
  ; 
  it 
  is 
  sometimes 
  interrupted. 
  The 
  

   form 
  is 
  a 
  little 
  stouter 
  than 
  that 
  of 
  D. 
  elongata.

  Eagle 
  Harbor, 
  Lake 
  Superior, 
  only 
  two 
  females 
  were 
  found. 
  Differs 
  from 
  the 
  pre- 
  

   ceding 
  by 
  the 
  broader 
  form 
  and 
  almost 
  regularly 
  rounded 
  sides, 
  as 
  well 
  as 
  by 
  the 
  finer 
  

   punctures 
  of 
  the 
  thorax- 
  From 
  the 
  following 
  species 
  it 
  differs 
  by 
  the 
  same 
  characters 
  

   and 
  also 
  by 
  the 
  pubescence 
  of 
  the 
  thorax 
  being 
  as 
  fine 
  as 
  that 
  of 
  the 
  elytra.
