  large 
  scattered

  Two 
  females 
  from 
  New 
  York. 
  More 
  ovate 
  and 
  less 
  slender 
  than 
  the 
  preceding, 
  

   entirely 
  of 
  a 
  blackish 
  brown, 
  almost 
  black 
  above 
  and 
  shining. 
  Head 
  flat 
  and 
  densely 
  

   punctured 
  iu 
  front, 
  convex 
  and 
  sparsely 
  punctured 
  behind, 
  clypeus 
  finely 
  margined. 
  

   emarginate 
  ; 
  thorax 
  twice 
  as 
  wide 
  as 
  the 
  head, 
  fully 
  twice 
  as 
  wide 
  as 
  long, 
  rounded 
  

   on 
  the 
  sides, 
  slightly 
  narrowed 
  at 
  the 
  base, 
  sparsely 
  and 
  coarsely 
  punctured, 
  with 
  a 
  

   transverse 
  smooth 
  space 
  before 
  the 
  middle. 
  Elytra 
  a 
  little 
  wider 
  than 
  the 
  thorax. 
  

   finely 
  punctured 
  ; 
  each 
  puncture 
  supports 
  a 
  very 
  minute 
  hair; 
  the 
  sutural 
  costa 
  is 
  very 
  

   strong, 
  and 
  there 
  are 
  some 
  faint 
  traces 
  of 
  the 
  dorsal 
  ones. 
  Propygidium 
  nearly 
  smooth, 
  

   pygidium 
  finely 
  sparsely 
  punctulate. 
  Breast 
  with 
  short 
  not 
  dense 
  yellowish 
  hair. 
  

   Abdomen 
  convex, 
  smooth 
  in 
  the 
  middle, 
  finely 
  punctured 
  at 
  the 
  sides, 
  but 
  more 
  

   coarsely 
  on 
  the 
  two 
  last 
  segments, 
  penultimate 
  joint 
  margined 
  behind 
  at 
  the 
  middle.

  Common 
  in 
  the 
  Middle 
  and 
  Southern 
  States. 
  The 
  only 
  satisfactory 
  difference 
  I 
  

   find 
  between 
  this 
  and 
  the 
  next 
  species 
  is 
  in 
  the 
  form 
  of 
  the 
  thorax, 
  which 
  is 
  here 
  

   much 
  more 
  rounded 
  on 
  the 
  sides, 
  and 
  slightly 
  narrowed 
  at 
  the 
  base. 
  The 
  other 
  dif- 
  

   ferences 
  noted 
  by 
  Burmeister, 
  such 
  as 
  the 
  greater 
  concavity 
  cf 
  the 
  clypeus, 
  the 
  longer 
  

   hair 
  of 
  the 
  pectus, 
  and 
  the 
  finer 
  punctures 
  of 
  the 
  pygidium 
  I 
  do 
  not 
  find 
  constant 
  ; 
  

   but 
  fearing 
  not 
  to 
  possess 
  his 
  species 
  I 
  have 
  placed 
  a 
  query 
  to 
  the 
  reference.
