  of

   berry 
  ; 
  a 
  specimen 
  of 
  very 
  large 
  size 
  was 
  found 
  by 
  Mr. 
  Joshua 
  Child 
  in 
  the 
  Sierra 
  

   Nevada 
  of 
  California. 
  The 
  head 
  behind 
  is 
  clothed 
  with 
  moderately 
  long 
  hair, 
  but 
  

   hardly 
  any 
  is 
  seen 
  on 
  the 
  thorax 
  ; 
  the 
  yellow 
  scales 
  on 
  the 
  latter 
  near 
  the 
  margin 
  are 
  

   elongate, 
  but 
  on 
  the 
  disc 
  they 
  are 
  lanceolate, 
  and 
  about 
  twice 
  as 
  long 
  as 
  their 
  width 
  ; 
  

   the 
  sides 
  are 
  obtusely 
  angulated 
  at 
  the 
  middle, 
  with 
  the 
  posterior 
  angles 
  very 
  obtuse. 
  

   The 
  yellow 
  scales 
  of 
  the 
  elytra 
  are 
  acute, 
  and 
  a 
  little 
  more 
  than 
  twice 
  as 
  long 
  as 
  their 
  

   width. 
  The 
  under 
  surface 
  is 
  clothed 
  with 
  pale 
  scales 
  with 
  snowy 
  bands 
  across 
  the 
  

   abdomen 
  ; 
  the 
  pectus 
  is 
  very 
  hairy, 
  the 
  posterior 
  tibiae 
  are 
  internally 
  clothed 
  with 
  

   long 
  hair. 
  The 
  feet 
  vary 
  from 
  ferruginous 
  to 
  blackish. 
  

  

  A 
  male 
  found 
  in 
  Kansas 
  is 
  remarkable 
  for 
  the 
  right 
  antenna 
  bifurcating 
  at 
  the 
  end 
  

   of 
  the 
  second 
  joint 
  ; 
  the 
  inner 
  third 
  joint 
  is 
  thick 
  and 
  short, 
  the 
  outer 
  normal 
  ; 
  the 
  

   outer 
  club 
  is 
  normal, 
  but 
  smaller 
  than 
  the 
  one 
  of 
  the 
  opposite 
  side 
  ; 
  the 
  inner 
  club 
  is 
  

   deformed, 
  being 
  composed 
  of 
  two 
  which 
  are 
  fused 
  together 
  at 
  the 
  middle, 
  forming 
  a 
  

   concave 
  mass, 
  of 
  which 
  the 
  upper 
  lamina? 
  are 
  much 
  longer 
  than 
  the 
  under 
  ones. 
  The 
  

   anterior 
  tibia? 
  are 
  almost 
  without 
  teeth.
