﻿MELOLONTHID^E 
  OF 
  THE 
  UNITED 
  STATES. 
  253 
  

  

  Middle 
  and 
  Southern 
  States, 
  rare. 
  The 
  pygidium 
  of 
  the 
  female 
  is 
  subtriangular 
  

   but 
  not 
  conoidal 
  ; 
  the 
  punctures 
  are 
  more 
  sparse 
  towards 
  the 
  apex 
  ; 
  the 
  sides 
  of 
  the 
  

   abdomen 
  are 
  punctured, 
  and 
  the 
  penultimate 
  segment 
  has 
  a 
  strongly 
  transverse 
  im- 
  

   pression 
  at 
  the 
  middle. 
  The 
  male 
  is 
  unknown 
  to 
  me, 
  but 
  the 
  penultimate 
  ventral 
  

   segment 
  is 
  described 
  by 
  Burmeister 
  as 
  having 
  no 
  transverse 
  elevation, 
  but 
  a 
  deep 
  

   impression. 
  

  

  Group 
  IX. 
  

  

  The 
  group 
  contains 
  a 
  number 
  of 
  large 
  oblong 
  species 
  having 
  the 
  upper 
  surface 
  

   pubescent. 
  The 
  head 
  is 
  moderate 
  in 
  size, 
  with 
  the 
  clypeus 
  emarginate, 
  not 
  broadly 
  

   margined 
  ; 
  the 
  thorax 
  is 
  broadest 
  at 
  the 
  middle, 
  and 
  more 
  or 
  less 
  narrowed 
  towards 
  

   the 
  base. 
  The 
  antenna? 
  are 
  10-jointed 
  ; 
  the 
  breast 
  is 
  clothed 
  with 
  hair. 
  The 
  ungues 
  

   are 
  toothed 
  at 
  the 
  middle, 
  but 
  the 
  tooth 
  is 
  as 
  long 
  as 
  the 
  apical 
  portion, 
  so 
  that 
  the 
  

   form 
  appears 
  almost 
  cleft. 
  The 
  spurs 
  of 
  the 
  posterior 
  tibia? 
  are 
  straight, 
  and 
  the 
  

   inner 
  one 
  is 
  fixed 
  in 
  the 
  male 
  ; 
  the 
  penultimate 
  ventral 
  segment 
  of 
  the 
  male 
  is 
  trans- 
  

   versely 
  impressed, 
  while 
  the 
  last 
  joint 
  is 
  broadly 
  foveate.

  Ancylonycha

  Common 
  in 
  the 
  Middle 
  and 
  Southern 
  States 
  ; 
  according 
  to 
  the 
  maturity 
  of 
  the 
  

   specimen 
  the 
  color 
  varies 
  from 
  blackish 
  fuscous 
  to 
  reddish 
  brown, 
  but 
  the 
  glaucous 
  

   lustre 
  is 
  always 
  distinct 
  in 
  well 
  preserved 
  specimens, 
  and 
  the 
  legs 
  are 
  ferruginous. 
  In 
  

   the 
  male 
  the 
  club 
  of 
  the 
  antenna? 
  is 
  as 
  long 
  as 
  the 
  remaining 
  portion 
  ; 
  the 
  hair 
  above 
  

   is 
  finer 
  and 
  less 
  dense, 
  but 
  the 
  hair 
  on 
  the 
  breast 
  is 
  a 
  little 
  longer 
  than 
  in 
  the 
  female 
  ; 
  

   the 
  penultimate 
  ventral 
  segment 
  is 
  deeply 
  transversely 
  impressed, 
  and 
  the 
  last 
  joint 
  

   marked 
  with 
  a 
  broad 
  round 
  impression. 
  

  

  The 
  present 
  species 
  agrees 
  with 
  the 
  figure 
  and 
  description 
  of 
  Knoch, 
  and 
  is 
  also 
  found 
  

   as 
  the 
  type 
  in 
  Dr. 
  Melsheimer's 
  collection. 
  That 
  described 
  by 
  Burmeister 
  is 
  some- 
  

   thing 
  different, 
  and 
  has 
  not 
  yet 
  fallen 
  under 
  my 
  notice: 
  it 
  differs 
  by 
  the 
  finer 
  and 
  

   more 
  depressed 
  pubescence 
  ; 
  by 
  the 
  hair 
  on 
  the 
  breast 
  being 
  scarcely 
  longer 
  (even 
  in 
  the 
  

   male) 
  than 
  that 
  on 
  the 
  abdomen, 
  and 
  by 
  the 
  pygidium 
  being 
  coarsely 
  punctured 
  with 
  

   a 
  smooth 
  middle 
  space 
  ; 
  in 
  the 
  present 
  species 
  the 
  punctures 
  are 
  scattered, 
  gradually 
  

   less 
  numerous 
  towards 
  the 
  tip.
