  reddish 
  brown; 
  pilosity 
  of

  and 
  thorax 
  

   gray, 
  abundant, 
  markedly 
  pollinose; 
  pile 
  of 
  abdomen 
  pale 
  tawny, 
  

   aggregated 
  into 
  irregular 
  spots 
  especially 
  on 
  segments 
  3-6, 
  spots 
  

   more 
  numerous 
  anteriorly 
  and 
  on 
  sides 
  of 
  both 
  tergites 
  and 
  sternites 
  ; 
  

   abdomen 
  nearly 
  circular 
  in 
  cross-section, 
  forming 
  almost 
  a 
  smooth 
  

   cone 
  based 
  on 
  hypopygium 
  ; 
  seventh 
  tergite 
  a 
  little 
  longer 
  than 
  sixth, 
  

   transversely 
  corrugated 
  on 
  posterior 
  third, 
  tapered 
  from 
  the 
  middle, 
  

   and 
  apiculate, 
  terminating 
  in 
  a 
  moderate 
  point 
  which 
  extends 
  well 
  

   beyond 
  hypopygium. 
  Sternum 
  without 
  keel; 
  sutures 
  between 
  ster- 
  

   nites 
  emarginate 
  medianly, 
  arcuate 
  laterally, 
  this 
  condition 
  most 
  

   pronounced 
  between 
  sixth 
  and 
  seventh 
  ; 
  eighth 
  sternite 
  almost 
  trans- 
  

   verse 
  posteriorly, 
  with 
  a

  emargination 
  ; 
  ninth 
  ster- 
  

   nite 
  very 
  narrowly 
  visible, 
  with 
  a 
  similar 
  but 
  smaller 
  emargination 
  ; 
  

   claspers 
  closely 
  fitting 
  the 
  upper 
  margin 
  of 
  hypopygium, 
  their 
  own 
  

   upper 
  margin 
  broadly 
  emarginate 
  medianly.

  apex 
  pro- 
  

   jecting
