Descriptions  of  new  species  of  DIUR:VAL.  L,EI>ID0PTERA 
found  within  the  lluited  States. 

BY   W.    H.    EDWARDS. 
Argynnis  Artonis. 

Male. — Expands  from  1.5  to  1.8  inch.  Upper  side  uniform  yellow-fulvous,  very 
little  obscured  at  base;  all  marks  delicate,  and  as  in  Eurynome ;  the  mesial  baud 
on  secondaries  made  up  of  separated  crescents  (in  the  examples  under  view.) 
Under  side  of  primaries  paler;  the  marks  in  cell  and  those  of  mesial  row  re- 
peated ;  the  P-shaped  spot  in  cell  fulvous  within ;  the  extra  discal  row  but  im- 
perfectly rejieated  and  all  the  marginal  markings  nearly  obliterated.  Secondaries 
light  yellow-buff,  sometimes  with  little  or  no  fulvous,  but  in  other  cases  mottled 
over  disk  with  pale  fulvous;  the  band  between  the  outer  rows  of  spots  buff, 
immaculate;  the  marginal  spots  faint,  as  on  primaries;  the  spots  of  disk  shaped 
as  in  Eurynome,  but  pale-yellow,  very  slightly  edged  on  basal  side  with  black, 
often  but  a  few  scales;  most  of  those  of  second  row  have  little  dusky  spaces  at 
their  outer  ends ;  no  trace  of  silver  on  either  wing.  Body  fulvous  above,  yellow 
below;  legs  reddish-yellow;  palpi  yellow,  at  tip  red;  antennre  brown  above, 
ferruginous  below ;  club  black,  at  tip  ferruginous. 

Female. — Expands  1.9  inch.  A  shade  redder  than  male,  the  costa  and  apex  (;f 
])rimaries  buff;  the  marginal  lines  heavier  and  more  or  less  confluent  on  both 
wings;  all  the  markings  heavier;  the  mesial  band  on  secondaries  confluent. 
Under  side  of  secondaries  cinnamon-brown  over  basal  area  and  disk,  the  apical 
area  and  hind  margin,  as  also  costa  next  apex  and  the  upper  half  of  cell,  yellow- 
buff;  spots  as  in  the  male,  the  marginal  almost  obsolete.  Secondaries  yellow-buff, 
all  spots  obsolescent. 

This  form  has  been  supposed  to  be  a  variety  of  Eurynome^  with  which 
species  it  flies  in  Colorado,  but  is  rare.  Mr.  Mead  met  with  three  or  four 
examples  in  1872,  though  he  took  great  numbers  of  Eurynome.  I  have 
received  a  single  male  from  Big  Horn,  Montana ;  and  recently  have  seen 
two  females  from  Wells,  Elko  Co.,  Nevada;  a  region  where,  so  far  as  I 
know,  Eurynome  does  not  fly.  These  formed  part  of  the  collection  of 
Mr.  J.  Elwyn  Bates  of  South  Abinglon,  Massachusetts ;  and  he  informs 
me  that  he  received  twenty-six  examples,  and  that  the  typical  Eurynome

was  not  taken  in  the  region  from  which  these  came.  Art  on  is  may  be 
distinguished  by  the  absence  of  silver  and  obHterated  marginal  spots 
on  both  wings. 

Argynnis  Liiliana,  II.  Edw.,  Proc.  Cat.  Acad.  Sci.  Dec.  1876. 

Mr.  Edwards  described  this  species  with  some  hesitation,  but  it  is  un- 
doubtedly a  good  species.  During  the  last  three  years  Mr.  0,  T.  Baron 
has  taken  very  many  examples  in  northern  California,  and  the  char- 
acteristics are  uniform.  I  have  living  larvae  at  the  present  time,  from 
eggs  obtained  by  him  from  a  female  in  confinement. 

Mr.  Edwards  says  of  this  species  :  "  It  is  intermediate  between 
A.  Calippe  Bdv.,  and  A.  Coronis  Behr,  partaking  of  the  characters  of 
both.  .  .  .  Upper  side  of  a  rich  reddish-brown.  Beneath,  the 
primaries  are  largely  suffused  with  reddish-brown,  as  in  Corotris,  but  the 
remainder  of  the  wing  is  occupied  by  bright  buff,  not  dull  ochreous,  as 
in  Corniiis.  The  silver  spots  of  the  margin  are  very  decidedly  triangular, 
and  not  ovate  as  are  the  apical  ones  of  Coroiiis.  On  the  lower  wings 
the  differences  are  more  apparent.  The  silver  spots  are  larger  propor- 
tionally than  in  any  other  species  with  whif;h  I  am  acquainted,  while  the 
sheen  of  the  silver  is  exceedingly  vivid  and  intense.  The  marginal  spots 
are  quite  triangular,  and  the  large  one  of  the  cell  more  decidedly  oblong 
than  in  either  Coronis  or  Cttlippe.  The  ground  color  of  the  wing  is 
bright  buff,  inclining  to  orange,"  etc. 

To  this  I  add,  that  the  species  is  of  medium  size,  the  %  expanding 
about  2  inches,  the  ?  about  2.2  inch. ;  that  the  female  is  paler,  some- 
what mottled  on  upper  side  with  yellow-fulvous  on  disk  of  primaries, 
and  the  submarginal  spots,  within  the  black  crescents,  are  yellowish  on 
both  wings.  So  the  spots  on  secondaries  which  represent  the  second  row 
of  silver  spots  are  paler  than  the  ground. 

Mr.  Neumoegen  has  received  from  Mr.  Baron  a  singular  variety  of 
Lilianu  %  ,  which  I  call  var.  Baroni.  The  two  marginal  lines  are  very 
heavy,  and  in  place  of  the  lunules  is  a  third  broad  line  crossing  the  whole 
wing ;  the  series  of  rounded  spots  on  each  wing  is  represented  by  a  demi- 
line  from  costa,  and  by  two  round  spots  in  the  two  median  interspaces, 
the  rest  of  the  row  wanting ;  and  the  mesial  bands  are  changed  from  a 
row  of  confluent  crescent  spots  to  a  continuous  zigzag  narrow  band  ;  the 
spots  in  cells  are  unchanged.  On  under  side  about  half  of  primaries  is 
yellow-buff;  namely,  all  except  the  area  next  base  below  median  and  the 
base  in  cell,  besides  two  spots  in  cell ;  secondaries  same,  yellow-buff ;  the 
margins  ferruginous-brown  and  disk  mottled  with  same  ;  on  primaries 
a  continuous  silver   bar   extends  from  costa  to  median  instead  of  the 


DIURNAL   LEPIDOPTERA.  3 

three  usual  silver  lunulate  spots,  and  on  the  subapical  patch  the  silver 
spot  is  twice  as  large  as  in  typical  examples.  Secondaries  have  a  con- 
tinuous submarginal  silver  bar  instead  of  lunules,  and  the  three  silver 
spots  of  second  row  next  costa  are  confluent,  making  one  great  spot. 
The  other  spots  are  not  changed. 

Eurygona  Abreas. 

Male. — Expands  1  inch.  Upper  side  dark  brown,  red-fulvous  over  disk  of 
])riinaries  and  to  base,  and  over  inner  half  of  secondaries.  Under  side  reddish- 
drab  ;  a  common  red  band  (color  red  lead),  crosses  the  middle  of  the  wings,  nearly 
straight  from  costa  of  primaries  to  lower  branch  of  median  on  secondaries,  then 
turning  up  to  inner  margin  ;  between  this  and  hind  margin  a  common  pale  brown 
stripe,  and  the  margins  are  narrowly  edged  with  same  color;  but  on  secondaries 
the  posterior  half  and  inner  margin  for  a  little  distance  are  edged  red;  along  this 
on  hind  margin  is  a  series  of  subcrescent  white  spots,  the  upper  one  in  upper 
median  intersjjace  being  surmounted  by  a  large  rounded  black  spot;  from  the 
second  branch  of  median  to  outer  angle  is  a  series  of  yellowish  spots  limited  by 
the  brown  strijje. 

From  1  S  ,  fnjm  Arizona,  in  collection  of  Mr.  Neumoegen. 

Liycsena  Cyna. 

Female. — Exj)ands  .9  inch.  Upper  side  purplish-blue;  primaries  have  the  apex 
and  hind  margin  ))roadly  bordered  with  fuscous;  at  the  end  of  cell  a  short  fine 
black  streak;  secondaries  narrowly  edged  with  fuscous  except  on  costal  margin. 
Under  side  light  brown-buff  thinly  washed  white ;  both  wings  have  a  marginal 
series  of  buff  spots  preceded  by  a  crenated  line  of  same  hue,  all  on  white  ground ; 
primaries  have  a  transverse  row  of  brown  .spots,  eight  in  all,  the  first  five,  counting 
ujj  from  inner  margin,  forming  a  convex  row  almost  parallel  with  hind  margin  ; 
the  line  then  bends  on  apical  area  and  the  last  two  spots  are  on  costal  margin  at 
one-half  and  three-fifths  the  distance  from  apex  to  base;  these  two  spots  are 
smaller  than  the  rest  and  in  line  with  them ;  over  the  sixth  spot  of  the  row  is 
another  one,  minute;  at  the  end  of  cell  a  buff  bar,  and  another  near  middle. 
Secondaries  have  a  much  curved  discal  row  of  smaU  spots,  seven  in  all,  besides 
three  across  basal  area  and  one  quite  at  base ;  in  cell  a  faint  bar. 

I  received  this  example  some  years  ago  from  the  late  Mr.  Boll,  who 
took  it  at  San  Antonio,  Texas ;  and  I  kept  it  hoping  that  in  another 
trip  which  he  planned,  he  might  find  the  male.  The  species  stands 
near  Gijdi^. 

Pamphila  Harpalus. 

Jl/a/e.— Expands  .95  inch.  Upper  side  red-fulvous  over  disk  and  costal  margin 
of  primaries ;  pale  brown  at  base ;  hind  margin  edged  broadly  with  same ;  stigma 
long,  slender,  widening  a  little  toward  base  and  bent  down,  black ;  in  subcostal 
interspaces  three  minute  fulvous  spots  and  two  others  in  the  border  opposite  cell. 
Secondaries  brown,  the  disk  fulvous,  obscured  except  in  discoidal  interspace  which 
is  clear  fulvous  nearly  to  hind  margin.  Under  side  of  primaries  pale  fulvous, 
yellowish  next  inner  margin,  ochreous  over  apical  area  ;  at  base  black.  Secondaries 
ochre-yellow;  on  disk  a  narrow  band  bent  near  outer  angle  and  extending  a  little 
way  toward  base;  in  cell  a  patch;  this  and  the  band  are  paler  than  the  ground 
but  are  not  very  distinct. 


4  WM.    H.    EDWARDS. 

Female. — Same  size.  Colors  paler,  the  brown  restricted ;  the  lower  median  and 
submedian  interspaces  a  little  obscured,  and  two  brown  streaks  in  discoidal  and 
upper  median  intersjjaces ;  the  brown  border  sends  out  long  serrations,  and  a  faint 
j)ale  band  crosses  the  wing  next  inside  the  border;  secondaries  have  the  disk  clear 
fulvous,  all  the  margins  brown,  the  hind  margin  serrated  as  on  primaries.  Under 
side  of  both  wings  uniform  yellow-buff;  the  irregular  band  of  primaries  is  better 
defined  than  on  upper  side,  paler  than  the  ground;  so  on  secondaries  the  band  is 
whitish,  of  same  shape  as  in  male  but  rather  more  distinct. 

From  1  %  ,  1  9  ,  received  in  1878,  from  Mr.  Morrison,  taken  in 
Nevada.     The  species  is  nearest  Sassacus. 

PanipSiila  B>eva,  Elw.,  Trans.  Am.  Ent.  Soc.  v,  289. 

I  described  a  female  of  this  species  received  from  Prescott,  Arizona  ; 
Mr.  Neumoegen  brought  from  South  Colorado  a  second  female  which 
differs  somewhat  from  the  type.  The  translucent  spots  on  primaries  are 
larger,  and  on  the  under  side  of  secondaries  are  indistinct  traces  of  two 
macular  bands,  one  abbreviated  on  middle  of  disk,  the  other  nearly  half 
way  between  the  first  and  hind  margin,  almost  perpendicular  to  inner 
margin  and  bending  to  costa  at  a  right  angle;  these  bands  are  brown, 
while  over  the  wing  is  a  gray  bloom.  The  same  bloom  covers  apex  of 
primaries.  In  the  type,  which  is  more  worn  than  the  Colorado  example, 
this  gray  surface  is  absent  and  the  brown  spots  do  not  appear.  But 
I  think  there  can  be  no  doubt  that  both  females  belong  to  one  species. 
The  S   is  yet  unknown. 

Pampliila  €abeln!«. 

Male. — Exjjands  1.2  to  1.3  inch.  Upper  side  yellow-fulvous;  the  hind  margins 
of  jirimaries  broadly  edged  with  pale  fuscous,  of  secjondaries  very  narrowly ;  the 
sexual  mark  long,  slender  and  curved;  on  costa  near  apex  are  two  or  three 
obsolescent  little  spots,  and  two  minute  ones  opposite  cell  in  marginal  border. 
Under  side  reddish-fulvous  over  both  wings,  except  the  apical  area  of  primaries 
which  is  yellowish,  and  inner  margin  pale  yellow;  a  little  black  at  base  and  a 
dusky  patch  at  inner  angle ;  secondaries  golden-yellow-fulvous,  with  a  few  small 
spots  of  paler  color;  one  in  cell  near  outer  end,  one  in  lower  subcostal  interspace, 
and  two  minute  spots  in  the  median  interspaces,  these  three  making  a  line  across 
the  disk ;  also  a  minute  spot  in  discoidal  intersj)aoe  near  margin.  One  example 
has  no  trace  of  these  spots  on  secondaries. 

From  8  %  's  taken  in  Nevada  by  Mr.  Morrison  in  1878.  The  species 
is  allied  to  P.  Oltoe  Edw. 

Pamphila  Yerus. 

ilfa/e.— Expands  1  inch.  Upper  side  yellow-fulvous,  the  margins  pale  fuscous, 
broad  on  primaries,  narrow  on  secondaries;  on  primaries  three  indistinct  subapical 
dots  on  costa,  and  a  series  of  small  spots  oblique,  crossing  median  intersi^aces ; 
sexual  mark  black,  slender,  broken  pn  lower  branch  of  median  but  not  separated, 
edged  by  black  somewhat  on  either  side ;  at  its  upper  end  a  fuscous  patch  connects 
it  with  the  marginal  border.     Under  side  of  both  wings  bright  yellow-fulvous; 


DIURNAL    LEPIDOPTERA.  5 

secondaries  immaculate;  primaries  have  a  little  black  at  base  and  a  streak  repre- 
senting the  stigma ;  the  indistinct  spots  of  upper  side  repeated,  but  still  more 
obscure,  scarcely  to  be  seen  except  in  certain  lights. 

Female. — Same  size;  generally  like  the  male  but  paler;  the  spots  more  definite 
and  semi-translucent ;  a  fuscous  patch  in  place  of  the  stigma.  Under  side  paler 
than  male. 

From  1  S  ,  1  9  ,  taken  at  Havilah,  California ;  and  in  the  collection 
of  Mr.  Henry  EJwards.     The  species  is  allied  to  Agricola  Bois. 

Panipliila  Regulus. 

Male. — Expands  1  inch.  Upper  side  black-brown;  primaries  have  a  straight 
black  sexual  mark ;  also  three  white  dots  in  the  subcostal  interspaces,  two  more 
at  end  of  cell  one  over  the  other,  two  near  hind  margin  opposite  cell ;  and  two 
streaks  or  spots  in  line  with  the  lest  mentioned  spots  and  making  with  them  an 
oblique  line  which  if  protracted  would  reach  middle  of  inner  margin.  Secondaries 
immaculate.  Under  side  paler,  the  sjjots  on  primaries  repeated  and  enlarged;  on 
secondaries  a  straight  line  of  four  small  spots  across  middle  of  wing,  two  at  right 
angles  with  the  outer  end  of  this  line  and  extending  up  costal  maagin ;  one  ou 
costal  margin  nearer  base,  and  one  in  middle  of  wing;  in  all  eight  spots.  Body 
above  and  below  concolored  with  the  wings;  palpi  buff. 

Female. — Expands  1.3  inch.  Same  color  and  marked  in  same  way,  but  the 
spots  larger. 

From  2  S  's,  1  9  i  sent  me  for  inspection  by  Mr.  J.  Elwyn  Bates  of 
South  Abington,  Massachusetts ;  and  received  by  him  from  upper  St. 
John's  River,  Orange  Co.,  Florida.  Near  Atxius,  but  very  much  spotted 
with  white. 

Pampliila  Lag  11s. 

Male. — Expands  1  inch.  Upper  side  yellow-fulvous;  primaries  have  a  very 
narrow  fuscous  border  to  hind  margin,  and  this  is  extended  round  apex  and  along 
eosta  for  a  little  distance.  Secondaries  have  a  still  narrower  border,  but  both 
costal  and  inner  margins  are  broadly  fuscous;  at  the  end  of  cell  of  primaries  the 
arc  is  black  and  subcostal  next  the  arc  is  bordered  black  ;  fringes  long,  pale  fulvous. 
Under  side  of  both  wings  light  3'ellow,  with  a  slight  fulvous  shade  over  middle 
of  primaries;  base  of  same  wings  and  part  of  inner  margin  black;  secondaries 
immaculate. 

I  formerly  recaived  a  single  male  of  this  little  species  ft-om  Mr.  Boll, 
taken  in  western  Texas;  and  recently  Mr.  Nenmoegen  has  brought 
another  male  from  Southern  Colorado,  taken  at  Oak  Creek  Canon.  The 
female  is  still  unknown.     The  species  is  allied  to  Delaicare. 

Painpliila  Taxiles. 

Male. — Expands  1.1  inch.  Upper  side  glossy  yellow-fulvous,  the  hind  margins 
bordered  narrowly  by  fuscous;  in  some  examples  the  dark  portions  are  greatly 
restricted,  forming  but  a  slight  edging;  costa  of  secondaries  fuscous;  primaries 
have  a  fine  black  stfeak  on  arc,  sometimes  Avanting;  fringes  of  secondaries  and 
along  inner  angle  of  primaries  fulvous,  the  remainder  fuscous.  Under  side  of 
primaries  paler:  basal  area  black,  with  a  spur  along  inner  margin;  hind  margin 
Lndistinctly  fuscous;  in  the  subcostal  interspaces  three  yellow  spots.     Secondaries 


(T  WM.    H.    EDWARDS. 

mottled  briglit  yellow  and  pale  red-brown,  the  yellow  prevailing  on  disk,  the 
other  bordering  hind  margin  and  forming  a  band  across  basal  area,  besides  a  demi- 
band  on  middle  of  wing  from  inner  margin. 

J'eOTa/c.— Expands  1.2  inch.  Upper  side  fuscous  mottled  with  pale  yellow 
fulvous;  the  hind  margins  broadly  fuscous;  the  basal  areas  pale  fuscous;  the- 
fulvous  occupying  the  disks,  not  clearly  defined,  and  especially  on  primaries  much 
obscured ;  primaries  have  three  translucent  spots  in  the  subcostal  interspaces ;  two 
fulvous  spots  anterior  to  these  last  and  opposite  cell ;  and  two  translucent  spots  of 
larger  size  in  the  two  median  interspaces;  in  some  examples  these  median  spots 
are  yellow,  not  translucent.  Under  side  of  primaries  blackish-brown  at  base, 
brown  over  apical  area  and  hind  margin;  the  costal  spots  and  those  against  cell 
repeated,  the  median  spots  indistinct.  Secondaries  red-brown,  indistinctly  mottled 
with  fulvous  across  middle  of  disk  and  along  costal* margin  and  at  base;  inner 
angle  brown-fulvous.  In  some  examples  this  wing  is  scarcely  mottled,  but  nearly 
uniform  red-brown,  and  is  flushed  with  grayish-purjile ;  so  also  is  the  apex  of 
primaries. 

Taxites  is  near  Zabulon,  a  species  which  varies  greatly.  The  most 
evident  distinction  consists  in  the  extent  of  the  fulvous  area  in  the  male, 
and  in  the  translucent  and  other  spots  on  fore  wings  of  the  female. 
I  have  examples  of  Za/mlon,  taken  at  Coalburgh,  which  have  the 
under  side  of  secondaries  mottled  in  same  way  as  in  this  western  form, 
and  examples  of  the  female,  especially  in  the  melanic  dimorphic  form 
Pocahontas  Scud.,  are  very  close  in  the  resemblance  of  under  side  to 
the  usual  t}^>e  of  Taxilcs.  This  replaces  Znbulon  on  the  Pacific  slope. 
1  have  examples  from  Arizona,  also  from  South  Colorado  and  Nevada, 
taken  by  Mr.  Morrison ;  and  Mr.  Neumoegen  found  several  at  Oak 
Creek  Canon,  South  Colorado.  Mr.  H.  Edwards  has  a  female  taken 
in  California. 

Amblyscirtes  Siinius. 

ilf«/e.— Expands  .85  inch.— Upper  side  grayish-brown  with  a  silky  gloss;  pri- 
maries have  a  white  spot,  fulvous  tinted,  at  end  of  cell,  and  a  bent  row  of  similarly

The  male  was  described  nearly  as  follows  : 

Expands  .9  to  1  inch.  Upper  side  glossy  dark  brown ;  primaries  have  three 
small  yellow  spots  near  apex,  a  point  in  each  of  the  two  median  interspaces  ;  also

Neonympha  Henshawi  =  Euptychia  Hennhawl,  Edw.,  Tr.  Am.  Ent.  Soc. 
5,  205. 
This  species  Wtis  originally  taken  in  Arizona  and  New  Mexico.      Mr. 
Neumoegen  took  several  examples  at  Oak  Creek  Canon,  Colorado.     The 
species   resembles  N.   Gemma  Hubner;    is   twice   as    hu'ge   and    russet^ 
beneath.     The  female  also  is  russet  above. 

I<einoilias  Nais  =  Ghrr/aophanus  Nais,  Edw.,  Tr.  Am.  Ent.  Soc.  5,  291, 

Described  from  a  single  %  taken  formerly  by  Dr.  Smart  in  South 
California,  and  a  9  received  from  Prescott,  Arizona.  Since  taken  at 
Denver,  Colorado,  (IS)  and  found  to  be  common  in  Southern  Colorado, 
at  Oak  Creek  Canon,  by  Mr.  Neumoegen.  The  species  belongs  to  the 
sub-family  Erycinidne,  not  to  the  Lycajnidae.  Its  habits  are  veiy  differ- 
ent from  Chrysophanus,  according  to  Mr.  Neumoegen  alighting  on  the 
sand,  etc. 

Mr.  Neumoegen  writes  thus :  "  Ntt  in  appeared  at  first  about  the 
middle  of  July,  in  Oak  Creek  Canon,  but  was  most  abundant  toward 
the  end  of  the  month  and  beginning  of  August,  entirely  disappearing 
by  the  middle  of  August.  It  was  always  found  on  open  clearings 
(which  in  a  Canon  means  the  highway,  as  there  is^  no  other  clearing), 
flying  from  10  A.  M.  to  2  p.  m.,  and  invariably  settling  near  moist 
places.  Its  flight  is  of  a  rapid,  zigzag  character,  much  resembling 
Melitfea." 

I  sent  a  pair  of  iVnis  to  Mr.  A.  Gr.  Butler,  to  ask  in  what  genua 
of  Erycinidaj  it  should  stand,  and  received  the  following  reply :  "  Zool. 
Dept.  Brit.  Mus.,  22  Nov.,  1880.  I  do  not  wonder  at  your  describing 
the  little  butterfly  as  a  Chrysophanus.  It  was  a  most  natural  mistake, 
considering  that  the  coloring  and   pattern  are  quite  Uke  that  genus^ 


8  WM.    H.    EDWARDS. 

and  quite  unlike  the  members  of  the  genus  to  which  it  appears  to 
belong.  In  structure  it  agrees  best  with  Apodemia,  (I  might  say,  it 
agrees  altogether),  but  the  pattern  of  the  under  surface  is  not  like 
any  member  of  that  genus  known  to  me,  being  more  like  the  arrange- 
ment found  in  Echenais.  If  color  can  be  called  a  structural  character 
therefore,  the  species  belongs  to  no  known  genus;  but  as  I  do  not 
consider  this  to  be  the  case,  I  should  certainly  refer  it  to  Apodemia, 
In  some  respects  Nais  reminds  me  of  Nemeobius,  but  the  much  less 
developed  club  to  the  antennte  at  once  precludes  the  possibility  of 
referring  it  to  that  genus." 

To  Apodemia  Kirby  refers  3Jormo,  Virgulti  and  allies,  which  in  my 
Catalogue  stand  under  Lemonias.  I  therefore  place  Nais  with  them, 
in  Lemonias,  Westwood,  which  covers  Apodemia. 

Melita'a  Arachne,  Edw.,  $,  Trans.  Am.  Ent.  Soc.  ii,  p.  372,  1869. 

I  described  Arachne  from  a  single  example  taken  in  Colorado,  and 
expressed  a  doubt  whether  it  might  not  be  same  as  Minitta,  Edw., 
Proc.  Acad.  Nat.  Sci.  Phila.  18B1,  161. 

Of  late  years  many  examples  of  both  forms  have  been  taken  in 
Colorado,  Arizona  and  West  Texas.  Mr.  Neumoegen  found  Arachne 
common  at  Oak  Creek  Canon,  South  Colorado ;  and  I  have  seen  it  in 
his  collection.  The  two  forms  are  equal  in  expanse  of  wing  in  the 
sexes,  the  2  %  's  measuring  from  1.2  to  1.4  inch,  the  2  $  's  about  1.4 
inch.  Both  sexes  are  alike  in  markings  and  color.  The  only  permanent 
diiference  which  I  have  been  able  to  discover  is  in  the  markings  about 
the  hind  margins  of  secondaries  on  under  side.  In  Minuta  this  margin 
is  white,  without  black  on  the  edge ;  a  little  within  is  a  fine  black  line 
and  en  this  line  rests  a  series  of  large  white  spots,  the  anterior  sides 
rounded.  The  posterior  side  of  each  spot  rests  on  the  black  line  and 
therefore  is  no  mere  curved  than  the  line  itself. 

In  Arachne  the  hind  margin  is  edged  wi'h  a  fine  black  line;  and 
instead  of  a  submarginal  fine  line,  the  spots  are  placal  on  black  ground 
and  the  posterior  side  of  each  is  largely  incurved,  sometimes  much 
angulated  and  this  makes  a  black  space  quite  unUke  the  mere  line  of 
Mhinta.  I  have  before  me  6  Minuta  %  9  ,  and  6  Arachne  %  9  ,  and 
ihcse  difi"erences  are  constant.  All  the  examples  which  Mr.  Neumoesen 
.--liowcd  me  Avere  of  the  Arachne  type.  80  were  four  (2  ^  .  2  9  ),  for- 
merly sent  me  by  Mr.  Boll  from  "West  Texas,  and  1  %  which  I  have 
from  Arizona.  This  is  enough  to  distinguish  one  form  from  the  other. 
and  I  shall  Catalog-ue  them  as  two  species.  4'>'achne  seems  to  inhabit 
a  more  southern  region  than  Minnta. 


ttlURNAL   LEPIDOPTERA. 


Motes  on  the  species  of  CAIiLIDRYAS  found  wifhin  the 
United  States. 

BY   W.    H.    EDWARDS. 

Until  Mr.  A.  Gr.  Butler,  in  his  "Lepidoptera  Exotica,"  London,  1874, 
«  monographed  this  group,  figuring  nearly  or  quite  all  the  known  species, 
and  that  in  both  sexes,  the  confusion  was  extreme,  and  no  apology  was 
necessary  on  the  part  of  other  recent  authors  for  any  errors  they  might 
have  fallen  into.  Now  there  is  no  excuse  for  error.  Mr.  Butler  had  all 
the  resources  of  the  British  Museum  collection  and  library  at  command, 
not  to  speak  of  the  many  other  British  collections,  and  his  authority  is 
sufficient  to  settle  any  doubtful  questions  in  this  direction. 

Following  the  best  light  I  could  find,  I  had  given  in  my  Synopsis 
(Vol.  i,  Butterflies  of  North  America,  1868-1872),  four  species  as 
belonging  to  our  fauna.

gave  the  North  American  species  thus :

10  WM.    H.    EDWARDS. 

In  my  Catalogue  1877,  following  Mr.  Butler,  I  gave 

1.  EUBULE, 

2.  Sennae, 

3.  Agarithe, 

4.  Philea, 

striking  out  Gipria  as  more  than  doubtful. 

Mr.  Strecker,  Syn.  Cat.  etc.,  1878,  with  no  reference  to  Butler's,  gives : 

1.  Argante,  Fabr.,  Syst.  Ent.  p.  470,

Finally  in  the  Synoptic  Table  of  Lepidoptera,  printed  in  Bulletin  of  the 
Brooklyn  Entomological  Society,  Vol.  i.  No.  9,  January;  1879,  we  have : 

1.  EuBULE,  Linn. 

9   var.  Sennae,  Linn. 

2.  Argante,  Fabr. 

3.  Philea,  Linn.,  evidently  without  knowledge  of  Butler  or  Scudder. 

Recent  authors  therefore  differing  so  much,  I  think  it  well  to  present 
again  Mr.  Butler's  view  of  these  species,  as  his  volume  is  not  accessible 
to  many  Lepidopterists. 

1.  Argante,  Fabr.,  Syst.  Ent.  p.  470,  is  not  a  North  American 
species,  but  the  species  found  within  the  United  States  and  taken  for 
Argante  is  Agarithe,  Boisduval.  The  most  northern  locality  given  by 
Butler  for  Anjante  is  Oaxaca ;  then  Honduras,  and  Central  and  South 
America.  Argante  is  characterized  by  a  "  zigzag  discal  series"  on  under 
side,  etc.,  and  Butler  refers  to  Swainson's  Illustrations  for  a  Plate  on 
which  he  says  both  sexes  are  correctly  figured.  This  is  in  First  Series, 
Swain.  Illus.  Vol.  i,  pi.  52.  The  "zigzag  band"  is  shown  to  be  com- 
posed of  two  oblique  red-brown  stripes  nearly  parallel  to  each  other,  one 
under  the  other,  but  unconnected.  Mr.  Butler's  figures  show  the  same 
peculiarity.  I  know  of  no  North  American  orange  species  which  has 
this  sort  of  stripe. 

2.  Agarithe,  Bdv.,  Spec.  Gen.  i,  623  ;  described  by  Butler,  thus  ; 

'•■  Male.—  Y&ry  similar  to  Argante,  but  paler,  the  front  wings  more  produced  at 
apex;  below  differs  from  Argante  in  the  oblique  band  of  front  wings  ivhich  is  con- 
tinuous and  not  angulaied  as  in  Argante. 


DIURNAL   LEPIDOPTERA.  11 

Female. — Above  generally  golden-orange,  sometimes  pinky- white ;  front  wings 
with  diflfused  orange  patch  over  end  of  cell;  a  brown  spot  at  end  of  cell;  apex 
an  oblique  series  of  spots  between  the  nervures  on  disk,  and  a  marginal  series 
terminating  nervures  black-brown;  hind  wings  with  costal  and  internal  ones 
rosy- whitish ;  three  or  four  blackish  spots  terminating  the  nervures  on  outer 
margin ;  wings  below  golden-yellow,  irrorated  with  ferruginous  atoms ;  front  wings 
with  base  and  apex  red;  a  bluish  subapical  nebula;  a  geminate  pearly  brown- 
zoned  spot  at  end  of  cell;  an  oblique  discal  brown  band  and  three  spots  between 
subcostal  branches ;  hind  wings  with  a  red  spot  at  base ;  a  transverse  streak  cross- 
ing cell  from  costal  nervure,  a  subcostal  spot  near  base,  and  a  semi-circular  series 
of  markings,  brown;  two  silver-centred  ring-spots  at  end  of  cell. 

Localities  : — "  Brazil ;  Yucatan  ;  Texas  ;  (white  var.).  %  var.  spotless 
below,  Santa  Martha." 

I  have  had  several  males  and  females  from  South  Florida  during  the 
past  season.  The  oblique  red-brown  band  is  distinct  on  under  side  of 
fore  wings  of  the  male.  The  color  of  under  side  is  bright  yellow.  One 
female  remains  in  my  collection  of  these  Florida  examples.  The  upper 
side  is  paler  orange,  the  ground  at  end  of  cell  deep  orange.  The  oblique 
band  is  obsolescent  on  upper  side  but  distinct  below.  And  the  other 
marks  agree  with  Mr.  Butler's  description. 

I  have  a  9  from  Kansas,  of  which  the  upper  side  is  ochre-yellow 
rather  than  orange,  and  the  oblique  band  is  broad  and  complete  on  Ijoth 
sides.  Another  from  Texas  is  yellow-white  on  upper  side,  or  sordid- 
white,  the  band  heavy  on  both  sides.  Another  ?  ,  Texas,  is  still  whiter, 
same  bands  on  both  sides. 

3.  Sennae.     Butler  gives  the  synonymy  thus :

"  Male. — Generally  smaller  than  Eubule ;  the  coloring  of  the  under  surface  deeper, 
and  the  markings  much  better  defined. 

Female. — Above  deep  golden-yellow,  sometimes  inclining  to  orange,  or  dirty 
white;  front  wings  with  internally  dentated,  well  defined  dark-brown  margin 
begini:iing  at  second-third  of  costa  and  terminating  at  anal  angle ;  a  large  black 
disco-cellular  spot,  and  a  subapical  series  of  anguhited  lunules  between  the  nerv- 
ures; also  a  point  of  the  same  color  between  naedian  branches;  hind  wings  with 
rosy  margin;  a  submarginal  series  of  fine  large  geminate  dark  brown  spots  at 
termination  of  nervures;  abdominal  and  basal  areas  pale  rosy;  under  surface  of 
wings  paler;  the  margin  with  band  and  spots  as  above,  but  deep  rosy;  front  wings 
with  large  geminate  silver-centred  ring-spot  at  end  of  cell,  and  a  zigzag  series  of 
irregular  characters  on  disk,  all  rosy-brown;  costa  rosy,  hind  wings  with  two 


12  WM.   H.   EDWARbS. 

silver-centred  ring-spots  placed  obliquely  at  end  of  cell  on  a  brownish  streak,  and 
encircled  by  a  series  of  bracket-shaped  characters  beginning  at  base  and  continuing 
in  the  form  of  a  heart  through  disk,  all  rosy  brown. 

Localities : — "  Brazil ;  Central  America ;  Mexico  ;  Texas  ;  Jamaica  ; 
Hayti,"  etc. 

"  The  Phcehis  Eubule  of  Hiibner,  Samml.  ex.  Schmett.  ii,  pi.  31, 1805, 
represents  the  two  common  forms  of  C.  Sennae  ;  we  have  both  examples 
from  Honduras."     Butler,  pages  59,  60,  plate  23,  figs.  1-4. 

Until  recently  I  have  been  unacquainted  with  the  %  of  this  species, 
though  I  have  seen  many  9  s,  and  have  for  years  had  several  in  my 
collection,  from  Texas  and  elsewhere.  But  in  collection  of  Mr.  Henry 
Edwards,  at  New  York,  I  saw  two  males  alike,  one  of  which  he  had 
taken  at  Mazatlan,  in  copulation  with  a  5  ^^^^  J^J  Texas  examples. 
The  other  %  Mr.  Edwards  gave  me.  It  is  so  much  like  Euhule,  common 
form,  that  it  would  be  overlooked  and  no  doubt  has  constantly  been,  as 
the  female  is  reported  from  many  localities  in  the  United  States,  This  % 
is  less  green,  more  yellow  than  Euhule  %  .  The  upper  side  is  immaculate, 
the  marginal  areas  being  nearly  just  as  in  Euhule.  But  the  under  side 
has  a  reddish  hue  upon  the  yellow ;  the  zigzag  streaks  on  fore  wings  and 
other  markings  described  by  Mr.  Butler  are  distinct.  So  all  those  on 
hind  wings,  "  the  series  of  bracket-shaped  characters  beginning  at  base  and 
continuing  in  the  form  of  a  heart  through  disk  "  being  clearly  defined. 

A  9  sent  me  by  Mr.  Scudder,  labelled  "  C.  Orhis,  Poey,  Florida  Keys," 
measures  2.6  inches.  Color  white  with  a  yellow  tint,  but  not  sordid. 
Hind  margin  of  primaries  edged  by  a  narrow  brown  band  made  up  of  a 
confluent  series  of  long  spots  crenate  on  inner  side ;  costal  margin  same 
dark  brown  two-thirds  towards  base ;  a  large  brown  discal  spot  with  an 
orange  streak  on  arc ;  on  the  subcostal  interspaces  are  three  little  brown 
spots  or  clusters  of  scales  in  line  near  costa,  and  this  row  bends  round 
apex ;  secondaries  edged  with  double-convex  brown  spots  which  fill  the 
interspaces.  Under  side  has  the  margins  rosy -brown,  the  "  zigzag  bands" 
distinct  and  the  "bracket-shaped"  spots,  etc. 

Another  9  from  Texas,  is  same  size  as  last  named,  but  sordid  white. 
Marks  same. 

I  have  also  a  small   9  from  Indian  Eiver,  measuring  but  2.1  inch. 
Color  of  the  %   described  from  Mayatlan.     Below  same  red  tint  as  that.^ 
and  marked  just  like  it.     I  had  taken  this  for  a  dwarfed  Euhulr,  but 
clearly  it  is  JSennae. 

4.  Eubule.     Mr.  Butler  gives  the  species  thus : 

%  Pap.  Euhule,  Linn.,  Syst.  Nat.  2,  p.  743. 


MTJRNAL   LEPlDOMEllA*  13 

"Male. — Wings  above  sulphur-yellow,  unspotted,  with  narrow  marginal  mealy 
band;  below  sulphur-yellow ;  front  wings  with  paler  internal  area;  an  irregular 
rosy-centred  ring-spot  at  end  of  cell,  and  a  deeply  bisinuate  series  of  eight  brown 
spots  beyond  it;  hind  wings  with  two  silver-centred  spots  at  end  of  cell,  encircled 
by  an  irregular  discal  series  of  tea  or  eleven  red-brown  scale-spots,  sometim^es 
obsolete. 

Female. — Wings  above  sulphur-yellow,  with  orange  margin,  the  nervures  termi- 
nating in  black  spots;  front  wings  with  large  black  disco-cellular  spots,  and  some- 
times with  an  indistinct  series  of  discal  spots  towards  apex ;  below  golden-yellow, 
the  margins  deeper  colored;  front  wings  with  a  large  geminate  silver-centred 
ring-spot;  the  discal  spots  as  in  %  but  redder;  hind  wings  with  two  silver-centred 
ring-spots  placed  obliquely  upon  a  squamose  rusty  band  at  end  of  cell,  and  en- 
circled by  a  discal  series  of  irregular  reddish  markings,  several  reddish  spots 
at  base." 

This  species  is  common  over  the  South  and  West,  and  is  sometimes 
taken  on  Long  Island,  or  further  up  the  coast.  It  is  occasional  at 
Coalburgh,  West  Virginia ;  and  in  season  of  1880  there  were  an  unusual 
number  seen  there.

Synopsis  of  the  IiAI»IFYRID.f<:  of  the  United  States. 

BY   JOHN   L.    LECONTE,    M.  D. 

The  term  Lampyridae  in  this  memoir  is  used  in  the  same  extended 
sense  as  in  my  work  on  Classification  of  Coleoptera  of  North  America. 
The  species  may  be  naturally  divided  into  three  sub-families  of  equal 
value,  as  follows : 

Middle  coxse  contiguous;  epipleurse  distinct 2. 

Middle  coxa;  distant;  epipleurse  wanting I.  Ltcid^. 

2. — Episterna  of  metathorax  sinuate  on  inner  side;  epipleurse  usually  wide  at 

the  base II.  LampyridvE. 

Episterna  of  metathorax  not  sinuate  on  inner  side;  epipleurse  narrow  at 

base III.  Telephorid^. 

The  relations  of  these  and  their  respective  tribes  have  already  been 
sufficiently  indicated  by  me  in  other  places*  in  a  condensed  manner, 
and  additional  remarks  will  be  found  below  under  the  appropriate 
headings. 

Since  publishing  the  popular  essay  on  Lightning  bugs  above  cited,  my 
attention  has  been  called  by  a  friend,  more  familiar  than  myself  with  the 
literatiu-e  of  physical  research  to  an  interesting  essay  by  Dr.  T.  L.  Phipson,"}" 
in  which  some  partially  successful  attempts  were  made  to  isolate  the  light 
giving  substance,  to  which  the  name  Noctilucine  was  applied.  Other 
memoirs  on  this  substance  are  cited  by  Dr.  Phipson,  but  notice  of  tliem 
would  unduly  extend  the  present  remarks.  | 

If  Dr.  Phipson  is. correct  in  stating  that  the  cavLse  of  luminosity  both 
in  living  animals  of  such  varied  grades  as  the  lower  marine  forms  of  Ufe, 
the  mp-iapoda  and  the  complex  terrestrial  insects,  and  in  the  decomposing 
masses  of  animal  and  vegetable  material  such  as  foxfire  and  putrid  fish  is 
identical,  these  phenomena  become  even  more  worthy  of  careful  study  than 
I  supposed  when  I  wrote  my  popular  essay  on  Lightning  bugs.  For  a 
substance  which  is  developed  not  only  by  normal  physiological  processes, 
in  the  bodies  of  animals  of  very  varied  sti-ucture,  but  by  the  somewhat 
fortuitous  processes  of  ordinary  putrifaction  should  certainly  be  within 
easy  reach  of  synthesis.

Dr.  Phipson  also  states  that  the  spectroscopic  examination  of  the  light 
from  these  varied  sources  is  contained  within  the  space  extending  from 
C  to  a  little  beyond  F,  "  but  its  brightest  portion  lies  between  E  and  F, 
and  in  most  cases  this  portion  only  is  visible,  and  the  light  appears  nearly 
monochromatic.     It  has  no  lines  nor  bands  of  absorption." 

There  are  several  remarkable  phenomena  exhibited  in  various  parts  of 
the  family  which  will  receive  more  attention  when  the  materials  have 
been  collected,  and  the  student  found  to  prepare  a  general  monograph. 
They  may  be  briefly  stated  as  follows,  for  the  purpose  of  guiding 
observations : 

1.  The  pupae  of  the  Lycidae  are  frequently  found  in  large  numbers- 
under  loose  pieces  of  bark,  suspended  closely  together  by  the  posterior 
extremity,  each  one  enveloped  in  its  own  larva  skin,  which  is  cleft  on  the 
pleural  lines  as  usual.  Nothing  of  this  kind  has  been  observed  in  the 
other  two  sub-families. 

2.  The  elytra  of  certain  Lycidas,  though  useless  in  flight,  are  expanded 
to  a  degree  unknown  in  any  other  Coleopterous  family. 

3.  The  sexual  differences  in  the  light  organs  of  various  genera  of 
Lampyridae  have  not  been  properly  recorded.  They  furnish  as  will  be 
seen  in  the  sequel,  good  generic  and  even  specific  characters. 

4.  The  enormous  vegetative  development  of  the  antennal  branches 
in  Phengodes,  and  the  entire  want  of  knowledge  of  the  females  of 
any  member  of  the  tribe. 

5.  The  investigation  of  the  relation  between  the  Phengodini  of  this 
continent  and  the  Drilini  of  other  regions,  with  a  view  to  the  possible 
union  of  the  two  tribes. 

6.  While  in  the  Phengodini  we  have  an  enormous  development  of 
antennal  surface,  we  have  in  Malthodes,  probably  the  lowest  form  in 
the  family,  an  equally  remarkable  growth  of  the  sexual  appendages 
of  the  male. 

Telephoridse  have  occurred  in  tertiary  strata  ;*  the  geological  history 
of  the  other  two  sub-families  is  unknown. 

Sub-family  I.— LYCID^. 

The  species  of  this  sub-family  are  diurnal  in  habits  and  are  found  on 
the  leaves  of  plants,  where  they  seek  their  insect  food. 

They  are  known  by  the  middle  coxae  being  rather  widely  separated 
by  the  niesosternum,  and  by  the  epipleurae  being  reduced  to  a  narrow 
thickened   marginal  line.     Besides  these  essential   characters  of  defini- 

*  Heer,  Insecteu  fauna  .  .  .  (Euingen  <fe  Eadoboj,  143. 


AMERICAN   COLEOPTEEA.  17 

tion,  other  characters  are  seen  in  these  insects  not  found  in  the  other 
sub-families. 

The  elytra  are  frequently  costate  and  coarsely  reticulate  with  fine 
elevated  lines  forming  a  coarse  net  work,  or  more  usually  a  regularly 
goffered  surface.  The  head  is  sometimes  prolonged  in  front  of  the  eyes 
into  a  long  narrow  beak,  which  in  other  species  becomes  broad  and  short 
and  in  many  of  the  species  entirely  disappears.  The  mandibles  are  feeble, 
slender  and  acute,  the  palpi  are  unequal  and  the  eyes  larger  in  the  % 
than  9  ,  though  never  very  large ;  they  are  widely  separated  above  and 
beneath.  The  antennj^  are  eleven-jointed,  but  the  second  joint  is  some- 
times very  short  and  inconspicuous ;  they  are  frequently  very  broad  and 
compressed,  and  the  joints  3 — 10  occasionally  emit  broad  branches,  more 
slender  and  longer  in  the  %  than  in  the  $  ;  frequently  too,  they  are 
only  slightly  compressed  and  subserrate,  in  this  case  the  second  joint  is 
very  distinct  and  one-half  as  long  as  the  third.  The  sexual  characters 
are  simple ;  the  ventral  segments  are  seven  in  the  $  ,  the  seventh  being 
lai-ge  and  slightly  nicked  at  the  tip  ;  they  are  eight  in  the  %  ,  the  seventh 
being  broadly  and  strongly  emarginate,  and  the  eighth  elongate-oval, 
moderate  in  size  and  prominent.  There  are  slight  differences  in  the  form 
of  the  two  last  segments  of  %  in  our  species,  but  as  they  are  readily 
recognized  by  other  characters  I  have  not  deemed  it  prudent  to  encumber 
the  tables  with  minutiae  of  such  small  import  which  would  probably 
tend  to  confuse  the  student. 

The  genera  represented  in  our  fauna  may  be  divided  into  three 
natural  groups :  the  first  is  typical  and  peculiar,  the  second  tends  to  the 
Lampyridae  (gen.),  and  the  tJiird  to  the  Telephoridae.

This  species  by  the  form  of  the  palpi,  antennae,  and  number  of  elytral 

costae,  seems  to  indicate  a  distinct  genus,  to  which  a  name  has  probably 

been  already  attached,  though  I  have  failed  to  identify  it  in  any  of  the 

works  within  my  reach. 

Calopteroii  retiieruni.— Black,  beneatli  mouth  and  joints  of  legs  and 
base  of  antennse  tinged  with  testaceous.  Antenna?  two-thirds  as  long  as  the  body, 
very  broadly  compressed,  second  joint  very  short,  inconspicuous,  third  not  as  long 
as  the  fourth,  outer  ones  gradually  a  little  narrower.     Palpi  broadly  dilated,  last

strongly  reflexed,  obliquely  converging  in  front,  hind  angles  long,  divergent,  disc 
dusky.  Elytra  with  the  humeri  and  a  narrow  transverse  band  about  the  middle 
fulvous;  sides  gradually  and  moderately  dilated,  regularly  rounded  behind;  sur- 
face hairy,  suture,  margin  and  two  discoidal  costse  strongly  elevated;  first  and 
second  interspaces  with  double  series  of  large  cells  which  are  not  very  transverse, 
as  in  reticulatum,  but  quadrate.     Length  6.7  mm.

lation of  the  elytra  is  almost  as  in  Csenio  diniiu'i'ata,  but  the  form  of  body, 
•antennae,  palpi  and  an-angement  of  color  are  as  in  Calopfemn  ti/pk-um. 

Calopteroii  tricarinatum.— Black,  above  fulvous;  eyes  rather  large, 
convex,  \y.\\\n  with  the  last  joint  trapezoidal,  not  longer  than  wide.  Antennae 
very  broad,  two-thirds  as  long  as  the  body,  second  joint  verj'-  small,  third  triangu- 
lar, longer  than  fourth,  4 — 10  triangular,  not  longer  than  wide,  outer  side  curved, 
distal  side  oblique,  angle  rather  acute,  eleventh  longer,  oval,  subsinuate  near  the

The  form  of  the  last  joint  of  the  palpi  seems  to  require  the  reference  of 
this  species  to  Calopteron,  though  the  reticulation  of  the  elytra  and  the 
form  of  antenna?  are  quite  different.  It  seems  to  belong  to  the  Section  A, 
ii,  of  Biologia  Centro-Americana,  (Lycidas,  p  13),  in  which  case  the  % 
antennae  would  be  pectinate.

Although  in  this  genus  the  prothoracic  spiracle  is  not  tubular  and 
prominent,  yet  in  all  other  respects  it  resembles  so  closely  the  preceding 
genera,  especially  Culojttiron,  that  it  cannot  be  naturally  separated  from 
them.  The  front  is  strongly  gibbous,  prolonged  into  a  very  short  tri- 
angular beak  ;  maxillary  palpi  dilated,  hist  joint  elongate,  cultriform,  the 
outer  margin  sinuate,  the  inner  one  rounded  into  the  tip,  which  is  obtuse.

very  short,  third  one-half  as  long  as  fourth,  4 — 10  broad,  in  1  each 
with  a  long  basal  process,  in  9  with  a  shorter  and  broader  medial  process 
gradually  occupying  the  whole  length  of  the  joint,  eleventh  joint  elongate, 
rounded  at  tip.  Prothorax  strongly  carinate,  sides  broadly  reflexed,  sinu-

Ill  tliis  genus  tlie  prothorax  is  without  cells,  sometimes  slightly  earinate

sometimes  the  alternate  lines  are  a  little  stronger,  so  that  they  become 
feebly  4-costate.  The  species  of  this  genus  are  found  on  botli  eoiitinents,

one,  with  which  by  modifications  in  different  directions  the  other  I'oriijs  can  be 
readily  harmonized:  thus  by  completing  the  side  walls  of  the  anterior  median 
cell  you  have  sculptilis,  by  obliterating  the  walls  of  the  anterior  median  cell  and 
retaining  the  carina  you  have  irilineatus ;  by  making  the  middle  j)OSterior  cell 
vanish,  but  retaining  a  carina  to  re])resent  its  walls,  you  have  crenatus ;  finally 
by  obliterating  the  cell  walls  of  the  disc,  retaining  only  the  basal  part  of  the 
middle  posterior  cell,  with  the  imperfect  transverse  elevated  line  connected  with 
it,  you  pass  over  to  the  genus  Plateros.  We  have  here  evidently  at  comjilex  in 
which  not  only  supposed  generic  characters  are  untenable,  but  the  species  are  also 
somewhat  plastic  and  difficult  to  define.

Sub-family  11.— LAMPYEID.E. 

The  species  of  this  sub-family  are  easily  separated  from  the  Lycida; 
by  the  middle  coxa;  being  contiguous,  and  the  epipleurie  wide  at  the  base 
of  the  elytra,  even  when  the  latter  as  in  some   9  9  are  very  short. 

From  the  Telephoridae  they  are  known  by  the  metathoracic  episterna 
being  sinuate  on  the  inner  margin,  a  character  first  observed  by  Duval, 
and  which  seems  to  me  to  have  much  value  in  apportioning  the  more 
difficult  forms  to  their  respective  groups. 

The  genera  examined  seem  to  indicate  two  tribes  ;  the  first  is  numerous 
on  both  continents,  especially  in  the  tropical  regions  ;  the  second  is  perhaps 
exclusively  American,  unless  it  can  be  united  with  Drilini.

Tribe  1. — Lampyrini. 

The  most  cliaracteristic  structure  in  these  insects  is  tlie  light-givuig 
apparatus  which  is  contained  in  the  posterior  abdominal  segments  of  most 
of  the  species,  though  it  is  quite  absent  in  some  genera. 

The  position  and  form  of  tlie  organs  diflfer  according  to  genus  and  in 
a  less  degree  according  to  species. 

Tn  most  of  the  genera  the  sexes  are  similar  in  appearance,  but  in  the 
Lampyres  -roup  the  $  are  larger  than  S  and  larviform,  with  short  elytra 
and  n.".  wings.  In  these  genera  the  eyes  of  the  %  have  their  maximum, 
and  those  of  the  9  the  minimum  development.  In  the  other  groups 
the  eyes  of  the  %  though  larger  than  those  of  ?  ,  are  not  remarkable 
or  disproportionate  in  size.  The  head  is  deeply  immersed  in  the  pro- 
thorax  which  is  foliate  at  the  sides  and  apex,  so  as  to  protect  the  head. 

The  antennas  are  approximate  or  moderately  separated,  and  vary  m 
form  according  to  group  and  genus.     Our  genera  seem  t.^  indicate'  the 
following  groups :

The  prothorax  is  less  prolonged  over  the  head  than  in  the  next  two

wanting.  The  eyes  are  larger  in  %  than  5  ■  but  are  separated  by  a  wide 
space  both  above  and  beneath  in  all  the  species.  In  the  %  the  last 
ventral  segment  is  small  and  narrow,  covered  l)y  the  scutate  last  dorsal, 
which  varies  in  form  according  to  genus  and  species.  The  light  organs, 
when  present,  are  more  developed  in  %  than  $  .  which  is  the  reverse  of 
what  obtains  in  the  group  Lampyres.  Tlie  head  is  always  covered  by  the 
hood-like  prothorax.  The  epipleiu'te  of  the  elytra  are  wide  at  the  base; 
the  inferior  (or  distal)  margin  is  reflexed.  and  converges  more  or  less  to 
the  lateral  margin  of  the  elytra.  The  elytra  vary  in  color;  in  the 
species  without  well-develo})ed  light  organs  they  are  black,  with  the 
single  excejjtion  of  F/jropi/r/d:  uidicta.  where  they  are  broAvn  margined

It  wdl  therefore  be  especially  necessary  for  the  inexperienced  stiulent 
to  ascertain  in  this  group,  to  what  genus  his  specimen  should  be  referred, 
before  he  attempts  its  specific  determination. 

There  are  in  many  families  of  Coleoptera  strong  resemblances  between 
species  of  diiferent  genera,  but  I  know  of  none  (with  the  exception  (jf 
certain  Rhynchophora),  so  deceptive  as  those  which  our  own  Hmited

stood, but  next  summer  when  living  specimens  can  be  obtained,  renewed  observa- 
tions will  be  made.  Dr.  Hagen  thinks  that  these  impressions  can  be  traced,  though 
less  distinctly,  in  other  genera  of  this  family  and  also  in  Elateridse.  I  have  not  yet

PHOTINUS  Lap.  emend.  Lee.  (nee  Lacordaire). 

This  genus  as  emended  by  me  (Pr.  Ac.  Nat.  Sc.  Phila.  1852,  33-1), 
differs  from  the  preceding  by  the  prothorax  not  at  all  carinate,  but 
usually  slightly  channeled,  and  more  obtusely  rounded  in  front.  The 
surface  is  pale,  tinged  with  rosy,  and  is  usually  marked  with  a  dusky 
spot  or  stripe.  The  light  organs  are  always  larger  in  the  %  than  in 
the  9  ,  and  in  the  latter  sex  vary  considerably  according  to  species ;  in 
the  %  they  occupy  the  whole  of  the  ventral  segments  from  the  fourth 
or  fifth  inclusive ;  on  the  fifth  and  sixth  segments  the  stigmatiform 
impressions  are  very  distinct,  except  in  the  division  Gynaptera^  where 
they  are  nearly  obsolete  ;  in  the  9  the  light  organs  occupy  the  middle  part 
of  the  ventral  segments,  and  exhibit  themselves  mostly  as  a  flat  elevation 
on  the  fifth  segment.  The  stigma-like  impressions  are  barely  or  not  visible 
in  the  9  ,  which  may  thus  be  easily  distinguished  from  the  9  of  the  species 
of  the  preceding  genus.  Some  of  the  species  are  among  the  most  abundant 
and  beautiful  of  our  lightning  bugs,  though  less  gregarious  than  Photuris. 

exist,  but  with  a  purely  normal  respiratory  function.  It  may  be  affirmed  with 
great  probability,  that  these  impressions  are  homologous  with  the  ventral  setigerous 
pores  or  fovese  of  Carabidse  and  Staphylinidse,  which  bear  the  so  called  ambulatorial 
setse.  In  Lampyridse  these  fovese  are  conspicuous  only  in  this  and  the  following 
genus  (Phoiinus),  so  far  as  the  genera  occur  in  our  fauna.

The  development  of  this  genus  has  been  traced  by  Mrs.  V.  0.  King, 
Austin,  Texas ;  and  the  resuUs  of  her  observation  are  pubhshed  in 
Psyche  iii,  51  —  53.  For  a  good  series  of  specimens  I  am  indebted  to 
Mrs.  King  and  Mr.  Belfrage.  I  have  separated  the  9  found  by  Mr. 
W.  31.  Davis  in  the  mountains  of  Kentucky  as  a  distinct  species,  on 
account  of  the  much  greater  length  of  the  prothorax ;  the  %  is  un- 
fortunately unknown.  The  light  organs  are  brilliant  in  the  $  ,  less  so  in 
the  S  .  The  prothorax  is  finely  carinate  and  the  elytral  costae  distinct.

As  there  is  no  other  character  available  at  present  for  the  distinction 
of  the  second  species,  a  longer  description  is  unnecessary. 

Group  4. — Luciolx. 
The  eyes  are  large,  convex  and  widely  separated  above  and  beneath  in 
both  sexes,  not  conspicuously  larger  in  %  ;  the  head  is  rounded,  narrowed 
behind  and  not  retractile ;  it  is  but  partially  covered  by  the  prothorax, 
which  is,  however,  of  the  usual  hood-like  form  and  rounded  in  front. 
The  antenna)  are  longer  than  one-half  the  body,  filiform,  slender,  not 
compressed,  inserted  near  the  anterior  margin  of  the  front,  and  moder- 
ately approximate ;  the  second  and  third  joints  are  about  equal,  and 
together  are  as  long  as  each  of  the  following  joints. 

The  sexes  are  similar  in  form  with  long  elytra  and  well  developed 
wings ;  the  light  organs  occupy  the  whole  of  the  fifth  and  following- 
segments  ;  stigma-like  pores  are  not  obvious,  being  situated  at  the  base 
of  the  fifth  and  sixth  segments  and  less  strongly  marked  than  in  Pyracto- 
mena  and  Photinus  %  .  The  seventh  ventral  in  9  is  ojjtusely  triangular ; 
in  %  the  fifth  and  sixth  are  broadly  emarginate,  the  seventh  is  smaller 
than  in  9  ,  sinuate  at  the  sides  and  prolonged  at  the  middle,  the  eighth 
is  a  little  wider  and  longer  than  the  prolongation  of  the  seventh.  In  our 
species  the  outer  (or  anterior)  claw  is  cleft  at  tip.  The  prothorax  and 
elytra  are  densely  rugosely  punctured,  the  former  is  yellow  with  a  black 
stripe  or  spot,  each  side  of  which  the  disc  is  red ;  the  latter  have  the 
whole  margin  and  frequently  a  discoidal  stripe  pale.  A  single  genus 
occurs  in  our  fauna  with  limited  representation.

Tribe  2. — Phengodini. 

The  prothorax  though  rounded  in  front  does  not  cover  the  head, 
which  is  exposed.  The  eyes  are  convex,  prominent,  and  widely  sepa- 
rated ;  the  antennae  are  not  approximate,  inserted  in  front  and  inside  of 
the  eyes,  and  are  plumose  or  flabellate  in  the  S  ;  (  $  unknown).  The 
mandibles  are  long,  slender  and  curved,  the  labrum  connate  with  the 
front,  small  in  Pterotus,  large  and  emarginate  in  Phengodes ;  the  middle 
00X33  are  contiguous,  the  metasternum  between  them  being  narrowly 
carinate ;  the  side  pieces  of  metathorax  are  broad  and  diagonally  divided. 
The  gula  is  deeply  impressed  or  excavated  in  all  the  genera.

closely,  but  the  prothoracic  differences  seem  to  warrant  their  reception 
as  distinct.

I  may  add  that  the  antennae  are  shorter  in  the  la.st  two  species,  being- 
less  than  half  as  long  as  the  body,  while  in  the  others  they  are  nearly 
two-thirds  as  long.  As  there  are  no  other  conspicuous  differences  than 
those  mentioned  in  the  table,  longer  descriptions  are  unnecessary,  and 
would  only  mislead  the  student. 

ZARHIPIS  n.g. 

This  genus  agrees  with  Fhengodes,  in  all  respects  except  the  following : 
The  head  is  less  deeply  concave  between  the  eyes,  and  not  transversely 
constricted  or  impressed  behind ;  epistome  elevated  above  the  labrum ; 
the  elytra  are  nearly  as  long  as  the  abdomen,  slightly  dehiscent  and 
rounded  at  tip ;  the  third  as  well  as  the  fourth  tarsal  joints  are  furnished 
beneath  with  a  distinct  membranous  sole  ;  the  seventh  ventral  is  acutely 
emarginate  ;  the  sixth  segment  is  also  emarginate,  but  the  seventh  is  cleft 
almost  to  the  base,  and  the  lobes  sometimes  overlap  behind  presenting  the 
appearance  of  a  narrow  closed  slit,  in  which  the  basal  part  of  the  eighth 
ventral  is  visible. 

Three  species  from  California  are  known  to  me  : 

Prothorax  with  side  margin  strongly  reflexed , 2. 

Prothorax  with  narrow  side  margin 3. 

2. — Blackish  piceous,  mandibles  and  j^rothorax  bright  rufo-testaeeous ;  base  of

Mastinocerini. 
These  are  small,  slender  insects,  having  the  antennae  biramose,  or  serrate 
but  not  flabellate  as  in  Phengodini,  the  branches  being  less  slender.  The 
eyes  are  small,  lateral  and  convex  ;  the  epistome  is  somewhat  convex,  and  the 
labruni  is  small  and  indistinct ;  the  mandibles  are  acute  but  not  prominent. 
The  maxillary  palpi  are  long,  the  labial  very  short ;  the  gula  is  less  deeply 
excavated  than  in  Phengodes^.  The  side  pieces  of  metathorax  are  long 
and  narrow,  diagonally  divided,  with  the  epimera  exposed.  The  elytra 
are  short,  dehiscent,  and  rounded  at  tip.

In  this  genus  the  labrum  is  small  and  indistinct,  and  the  epistome 
slightly  convex,  more  advanced  than  in  the  two  preceding  genera  ;  the 
head  between  the  eyes  is  flattened,  scarcely  concave ;  the  gula  is  much 
less  excavated,  and  the  maxillary  palpi  are  long,  flattened,  not  slender, 
with  the  last  joint  triangular  or  rather  securiform.  The  antenna)  are  not 
longer  than  the  head,  biramose,  with  the  branches  shorter  and  stouter, 
though  still  flexible.  The  eyes  are  lateral,  moderately  large  and  convex. 
The  flanks  of  the  prothorax  are  acutely  margined,  flat,  not  concave,  the 
edae  (if  the  disc  is  not  maroined  nor  flattened.  The  metasternum  is 
longer  than  usual,  with  narrow  side  pieces,  but  the  epimera  are  large. 
The  elytra  are  less  than  one-half  as  long  as  the  abdomen ;  dehiscent  and 
rounded  at  tip,  without  distinct  epipleurae.  Legs  slightly  compressed ; 
joints  1 — 4  of  tarsi  gTadually  a  little  shorter  and  narrower,  fourth  small, 
not  lobed  beneath.

I  am  also  indebted  to  Mrs.  King  for  a  larva  of  Mastinocerus,  of  slender, 
cylindrical  form  and  pale  color.  It  was  feebly  luminous,  and  lived  upon 
small  snails.  The  perfect  insect  is  thus  mentioned  in  a  letter,  the  observa- 
tions being  made  upon  a  specimen  attracted  by  the  lamp  :  "  June  4th  saw 
running  rapidly  over  the  table  near  a  lighted  lamp,  a  small  Coleopter ; 
it  was  twisting  its  abdomen  up  over  its  wings,  and  evidently  trying  to 
straighten  them  out,  as  they  seemed  moist  and  twisted  at  their  ends.  The 
general  appearance  suggested  Mastinocerus,  and  acting  on  this  thought, 
I  captured  it  and  sat  up  till  a  late  hour  to  be  assured  of  the  truth.     The 


AMERICAN    COLEOPTERA.  41 

insect  was  in  a  small  vial  and  moved  quickly.  It  gave  out  light  con- 
spicuously from  the  head,  feebly  from  the  anal  end,  and  still  more  so  from 
about  the  base  of  the  abdomen.  The  light  seen  in  the  head,  though 
visible  in  the  dark  as  a  round  spot,  yet  when  taken  into  a  room  obscurely 
lighted  was  invisible  from  above ;  but  when  the  insect  was  suddenly 
thrown  upon  its  back  a  light  no  larger  than  a  pin  point  was  seen  just 
about  the  junction  of  the  head  and  prothorax." 

C  ENOPHEKGrS  n.  g. 

I  have  established  this  new  genus  upon  a  small  Californian  species, 
which  greatly  resembles  in  appearance  Mastinocerus  fexanus,  but  differs 
by  the  antennje  as  long  as  the  head  and  prothorax  ;  the  prothorax  a  little 
longer  than  wide,  with  the  lateral  edge  distinct  only  behind  the  middle, 
and  quite  obliterated  in  front.  The  maxillary  palpi  are  elongate  and 
slender,  with  the  last  joint  long  and  cylindrical.  The  seventh  ventral 
segment  is  more  broadly  emarginate,  and  the  eighth  comparatively  larger. 
In  all  other  respects  it  closely  resembles  3J.  texinius,  except  that  the 
sculpture  is  finer. 

C  debilis. — Elongate,  blackisli  pioeous,  punotulatc  and  pubescent.  Pi-o-

apex  truncate,  sides  parallel,  base  and  hind  angles  strongly  rounded ;  testaceous, 
piceous  near  the  base.  Elytra  flattened,  half  as  long  as  the  abdomen,  finely 
scabrous-punctate,  sides  somewhat  rounded  with  a'  submarginal  elevated  line  from 
before  the  middle  nearly  to  the  tip.  Legs  and  last  segment  tinged  with  testaceous.

TYTTIIOXYX  Leo. 

The  well-known  but  not  al)un(laiit  species  which  is  the  type  of  this 
genus,  is  of  somewhat  difficult  location.  Its  appearance  would  indicate  a 
relatio  iship  with  the  Malthini  group  of  Telephorida;,  but  after  a  careful 
study  of  its  characters  I  am  inclined  to  believe  that  its  true  position  is 
near  Maafinorerus  and  Cenophenr/u.<<,  with  perhaps  a  closer  tendency 
towards  Drilus  than  is  exhibited  in  those  genera. 

The  characters  have  been  sufficiently  given  l)y  me  in  other  places  to 
permit  of  the  easy  recognition  of  this  genus,  but  in  order  to  substantiate 
the  opinicm  above  expressed  it  is  now  necessary  to  go  into  greater  details. 

Head  broader  than  long,  deflexed,  eyes  small,  rounded,  convex,  promi-

rowed and  pointed  behind,  not  sinuate  on  the  inner  margin,  epimera  ex-

ginate  behind.  Wings  straight,  extending  along  the  dorsal  surface  of  the

Sub-f\imily  III.— TELEPHORID^E. 

The  insects  of  this  sub-family  are  -closely  related  to  the  Lampyridse 
genuini,  but  are  easily  known  by  the  stronger  development  of  the  mouth 
organs,  the  smaller  size  of  the  eyes,  which  permits  the  antenn;^  to  be 
widely  separated  at  the  base,  and  by  the  straight,  or  nearly  straight  out- 
line of  the  inner  side  of  the  metathoracic  episterna. 

Light  organs  do  not  exist  in  any  of  the  species,  and  the  sexes  are  very 
similar  in  form,  differing,  at  most,  by  the  length  of  the  antenna?  and  the 
outline  of  the  sides  of  the  prothorax.  Sexual  characters  are  also  seen 
in  the  last  segments  of  the  abdomen,  especially  in  Chau/iognafhus  and 
Mdlthodea  ;  in  the  latter  genus  the  claspers  assume  large  size  and  great 
complexity.  In  a  few  instances  tibial  and  tarsal  characters  distinguish  the 
sexes,  and  in  Biiany  species  of  Telepliorus  the;  ungues  are  quite  different. 

I  have  excluded  the  singular  genus  Ometliea  from  this  sub-family.  It  is 
not  a  Lampyride,  but  where  it  may  be  suitably  placed  I  do  not  know. 

Two  tribes  may  be  recognized  in  our  fauna : 

Mentum  very  long,  wider  in  front CuAtiLioGNAXHiNi. 

Mentum  sm;ill,  quadrnte TELKPHoniNr. 


AMERICAN    COLEOPTERA.  43 

Tribe  1. — Chauliognathini. 
This  tribe  consists  of  but  one  genus  represented  in  our  fauna  by  a 
moderate  number  of  species.     They  are  much  more  numerous  in  Tropical 
America,  but  so  far  as  I  am  aware  do  not  occur  in  other  countries. 

CHAUI.IOGIVATHIIS  Hentz. 

This  genus  differs  from  all  others  in  our  fauna  not  only  by  the 
elongated  head,  and  singular  structure  of  the  maxillary  lobe  which  has 
a  long  extensile  and  contractile  fleshy  filament,  but  also  by  the  peculiar 
arrangement  of  the  under  surface  of  the  prothorax,  and  the  sexual 
characters  of  the  %  . 

The  prosternum  is  but  feebl}  developed,  and  separated  by  membrane 
from  the  surrounding  parts.  The  trochantin  is  very  large,  triangular  and 
flat,  and  the  inflexed  flanks  wide  and  concave ;  the  two  gular  plates  at 
the  anterior  margin  of  the  prosternum  are  large  and  prominent,  dipping 
perpendicularly  inwards.  The  mentum  is  very  long  and  narrow,  a  little 
broader  in  front ;  the  gailar  sutures  run  from  the  hind  angles  of  the 
mentum  obliquely  inwards,  and  coalesce  on  the  median  line,  almost  to 
the  hind  margin  of  the  lower  floor  of  the  cranium. 

The  last  ventral  segment  of  the  %  is  elongate-oval,  convex,  and  of 
firmer  corneous  consistency  than  the  other  segments;  the  penultimate 
ventral  is  emarginated  broadly  and  deeply  by  the  convexity  of  the  last 
segment ;  from  the  terminal  opening  between  the  last  ventral  and  dorsal 
is  frequently  seen  protruding  a  pair  of  claspers,  of  slender  curved  form, 
hooked  at  the  end  and  fringed  on  the  inner  margin  with  spines,  thus 
resembling  the  inner  lobe  of  the  maxillae  of  Carabidfe. 

These  characters  and  those  already  given  by  me  in  the  Classification 
(p.  186),  abundantly  indicate  the  propriety  of  recognizing  this  type  as  a 
separate  tribe. 

In  several  species  the  antennae  in  the  %    are  longer  than  in  the   9  , 
and  the  outer  joints  are  somewhat  broader ;  but  there  is  not  sufficient 
difference  in   this   respect  to  be   worth   indicating  among  the    specific 
characters  in  the  tahle.

Group  1. — Podahri. 
Although  as  will  be  seen  below,  the  species  of  this  group  differ  in  the 
form  of  palpi,  as  well  as  in  the  tarsal  claws,  they  seem  to  me  to  indicate 
but  one  natural  genus.     They  are  more  numerous  in  the  northern  part 
of  the  Continent,  and  gradually  fade  out  towards  the  tropics. 

FODABRIJS  Westwuod. 
In  this  genus  the  gular  sutures  are  confluent  at  the  median  line,  and 
the  head  is  prolonged  and  narrowed  behind  the  eyes,  so  as  to  form  a 
distinct  neck  not  covered  by  the  prothorax,  which  is  nearly  truncate,  or 
even  s(jmewhat  emarginate  in  front.  The  seventh  ventral  segment  of 
the  %  is  truncate,  and  the  eighth  is  exposed,  sometimes  triangular, 
sometimes  with  parallel  sides  and  obtusely  rounded  at  tip.  The  seventh 
ventral  of  the  9  is  triangular,  subsinuate  each  side  near  the  tip,  which 
is  frequently  slightly  nicked,  though  I  have  not  found  use  for  this 
character  as  a  specific  distinction,  since  from  the  drying  of  the  specimens 
it  is  difficult  to  observe.  The  three  divisions  are  so  diff"erent  as  almost 
to  entitle  them  to  rank  as  distinct  genera,  though  some  forms  link  them 
together  rather  closely.

The  numerous  spi^cies  of  this  giMiiis  prestait  at  times  sexual  differences 
in  the  form  of  the  prothorax  and  the  tarsal  claws,  which  render  the 
distinction  of  species  somewhat  uncertain.  They  are  likewise  of  variable 
color  and  soft  texture,  so  that  in  dried  specimens  the  form  cannot  be 
ac-curati'ly  defined.  The  present  table  may  th.-refore  be  considered,  while 
an  improvement  upon  the  crude  work  of  my  first  synopsis,"}"  only  as  a

collected  from  the  same  locality  and  tree,  the  limits  of  variation  may

The  table  of  species  given  by  me,*  requires  modification  to  permit 

the  introduction  of  several  new  species,  which  have  since  been  collected. 

To  avoid  the  inconvenience  of  referring  to  the  previous  volume,  I  have 

changed  its  form  as  follows :  f  the  characters  being  taken  from  the  S  %  ■ 

Base  of  prothorax  broadly  rounded,  not  lobed,  sides  excavated  into  a  deep 
round  cavity  near  the  base ;  both  angles  of  the  excavation  acute,  ante-basal 
appendage  acute,  spiniform A. 

Base  of  prothorax  lobed,  excavation  of  hind  angles  parfrly  basal,  angles  there- 
fore not  very  distinct  though  acute,  anterior  margin  of  excavation  sinuate  with 
two  prominent  but  rounded  angles ;  ante-basal  appendage  acute,  spiniform,  directed, 
acutely  backwards B. 

Base  of  jjrothorax  lobed,  deeply  foveate  inside  of  the  hind  angles  which  are 
therefore  more  prominent  and  acute;  incisure  near  the  base  moderately  deep,  with 
the  anterior  angle  rounded;  ante-basal  process  compressed,  rounded  at  tip C. 

Base  of  prothorax  not  lobed.  broadly  reflexed ;  excavation  entirely  lateral, 
anterior  angle  of  incisure  nearly  rectangular,  hind  angle  long,  acute,  produced 
into  a  slender  filament  which  is  bent  forwards D. 

Base  of  prothorax  not  lobed,  posterior  process  of  incisure  not  ante-basal,  as  in 
the  preceding  groups  of  species,  but  proceeding  from  the  base  itself,  by  an  exten- 
sion of  the  hind  angles;  this  process,  as  well  as  the  anterior  one  is  compressed 
and  (ihtusp  at  tip E.

Yellow  testaceous,  head,  antenna;  and  legs  more  or  less  dusky;  9  prothorax  very

t  It  must  be  noticed  that  in  this  gcMis,  as  in  several  others  in  Ooleo])tera,  (he 
specific  characters  are  exhibited  chiefly  in  the  %;  in  not  a  small  number  of  in- 
stances in  such  genera  the  9  9  "^f  different  species  are  as  yet  uudistinguishal)le. 
Some  of  the  sexual  characters  in  this  genus  seem  to  have  escaped  the  attention  of 
European  observers.  The  anterior  claw  of  the  front  tarsi,  namely,  of  the  9  's 
more  or  less  toothed  at  base,  and  the  inflejfed  flank  of  the  prothorax  at  the  first 
quarter  of  its  length  with  a  fine  transverse  line,  which  runs  to  the  side  margin, 
and  rejire.'sents  the  nick  already  mentioned  as  occurring  in  both  sexes  of  Polemius. 
The  penultimate  ventral  segment  is  cleft  to  the  base  in  the  %  ,  exposing  the  wliole 
length  of  (lie  eighth  segment.

Group  3. — Maltliini. 
The  species  of  this  group  are  of  small  size  and  weak  structure, 
remarkable  chiefly  for  the  short  elytra,  which  leaves  the  wings  partly 
exposed  and  folded  along  the  dorsal  surface  of  the  abdomen.  I  have 
modified  the  group  as  exposed  by  me  in  Classification  Col.  N.  Am.,  by 
removing  Ti/tthonyx  which  seems  to  have  no  relation  to  the  other  genera 
and  to  resemble  them  superficially  merely  by  the  abbreviated  elytra. 

The  wealth  of  variation  in  sexual  characters  is  greater  in  this  group 
than  in  almost  any  other  in  Coleoptera.  In  Ichfht/urus  it  afifects  the  middle 
legs  of  the  S  ,  and  in  MnltJwdes  the  last  abdominal  segments  of  both 
sexes,  and  the  forms  of  the  claspers  are  ([uite  as  complex  as  those  repre- 
sented by  Baron  R.  Osten  Sacken  in  the  Tipulidas,  with  short  palpi,  Proc. 
Acad.  Nat.  Sc.  Phila.  1859,  pi.  3  &  4.  The  species  are  probably  numerous 
but  have  not  yet  received  much  attention  from  collectors.  The  European 
s])ecies,  which  run  somewhat  parallel  with  ours,  have  been  excellently

make  a  satisfactory  comparison  between  it  ami  Tri/pherus  Lee.  {Lijyerus 
Kiesenw. ),  wliich  is  somewhat  unfavorable  to  the  retention  of  the  hitter 
as  a  distinct  genus,  though  in  the  present  condition  of  nomenchiture  it 
cannot  be  properly  suppressed.  The  enormous  inflation  of  the  middle 
thighs  of  the  %  in  /.  discoidalis,  the  extremely  prolonged  spinil'orm 
trochanters,  and  the  very  short  tibi;e  of  the  same  pair  of  legs  would  lead 
one  on  superficial  inspection  to  regard  the  two  insects  as  distinct  generic 
types.  But  I  find  that  in  the  S  of  T.  latipcnnis  the  middle  trochanters 
are  larger  than  in  the  9  ,  ])ointed  at  the  end  and  angulated  or  even  toothed 
near  the  base ;  the  middle  thighs  are  also  decidedly  thicker  than  in  the 
9  ,  though  there  is  no  difference  in  the  tibiae.  The  last  abdominal  seg- 
ments are  similarly  modified  in  the  two  species,  though  much  more  strongly 
so  in  the  Oriental  than  in  the  American  species.  In  the  former  the  last 
dorsal  is  emarginate  or  bilobed,  and  is  moreover  deeply  excavated  beneath  ; 
the  seventh  ventral  is  truncate  behind,  and  the  eighth  narrower  and 
mucli  smaller.  In  T.  latipennis  the  last  dorsal  is  only  broadly  emar- 
ginate, and  there  is  a  small  anal  segment ;  the  seventh  ventral  is  deeply 
emarginate,  the  eighth  is  more  complex  in  arrangement  with  some  small 
processes,  which  are  difficult  to  describe,  and  as  there  is  but  one  species, 
quite  unimportant  for  the  recognition  of  the  same.  The  eyes  in  both 
genera  are  large  and  prominent  in  the  %  .

American  torticollis  in  haAang  the  %  antenna  in  no  respect  distorted 
or  different  from  those  of  the  9  ,  but  this  is  a  character  of  merely

slender,  the  thighs  and  tibiae  somewhat  curved.  The  penultimate  ven-

oval,  large  and  convex,  very  much  as  in  Chauliognathm.  The  an-

it  necessary  to  change  at  present  the  name  of  the  species  described  by  me.

*  This  generio  name  should  probably  be  rejeoted  for  the  speoies  here  mentioned ; 
it  was  proposed  (Ann.  Soo.  Ent.  Fr.  1st,  ii,  136),  for  species  with  ramose  antennae; 
the  universally  known  and  common  species,  atra  Fabr.,  is  not  mentioned  among 
them,  and  is  referred  to  by  Laporte  under  Lucernuta,  the  second  division  of 
Photinu.t,  as  No.  25,  P.  laticorni.i,  ibid.  144.  It  is  quite  evident  that  the  super- 
ficially observed  characters  used  by  him,  like  those  of  Motschulsky,  can  have  no 
significance  in  a  system  like  that  which  I  have  here  attempted  to  introduce,  for 
the  very  next  species  of  Photinus  {Lucernuta),  is  described  as  having  a  "  luminous 
spot  at  the  middle  of  the  fourth  ventral  segment."  This  position  of  the  light- 
organ,  barring  the  error  in  the  numbering  of  the  segments  would  place  at  least 
that  speoies  of  Lucernuta  in  the  neighborhood  of  Pyractomena.  In  the  confusion 
of  nomenclature  thus  produced  it  would  perhaps  be  easier  to  retain  for  our  species, 
and  for  as  many  from  tropical  America  as  are  found  to  be  congeneric  with  them, 
the  Dejeanian  name  Lychnuris,  fir.st  defined  by  me  in  Proc.  Acad.  Nat.  So.  Phila. 
ii,  332.  Since,  however,  I  am  neither  a  "purist,"  nor  " resurrectionist,"  but  an 
humble  conveyor  of  thought,  endeavoring  only  to  state  distinctly  the  relations 
of  the  objects  of  which  I  have  occasion  to  write,  I  leave  this  and  many  similar 
questions  for  those  whose  tastes  lead  them  in  another  direction.

the  description  occurs  in  northern  Europe,  the  name  has  been  traditionally  assigned 
to  our  common  North  American  species,  and  there  seems  to  be  no  good  in  sub-

fThe  Mexican  Lump,  tritineata  Say,  (Bost.  Journ.  Nat.  Hist,  i,  157;  ed.  Lee  ii, 
634),  with  which  Motschulsky  compares  this  species,  is  evidently  quite  different  to 
it  in  havinff  two  or  three  lines  on  each  elvtron  vellowisli.

In  concludiiiii'  this  paper,  I  have  only  to  regret,  that  although,  several 
of  my  friends,  who  have  collaborated  with  me,  for  the  procuring  of 
material  to  render  it  as  perfect  as  possible,  the  position  and  affinities  of 
the  tribe  Phengodini  must  still  remain  uncertain,  in  consequence  of  the 
ignorance  in  which  we  remain  in  regard  to  the  habits  of  the  species,  and 
the  form  of  the  females.  It  may  be  inferred  from  the  observations  of 
Mrs.  King  on  the  larva  and  male  imago  of  Mastinocerus  that  they  are 
luminous  in  all  stages  of  development.  This  inference  must,  however, 
be  confirmed  by  those  who  have  the  opportunity  of  observing  in  a  living 
condition  the  genera  and  species  of  the  tribe,  which  as  will  be  seen  in 
the  foregoing  pages  are  widely  distributed.  The  male  of  Pterotiis,  as 
I  have  been  recently  informed  by  Mr.  Rivers,  flies  in  the  evening  twilight, 
but  I  have  not  yet  learned  if  it  has  any  luminous  power.

ReTision  of  the  species  of  P©L,YPHY1.1.A  of  the  United 

States. 

BY    GEORGE    H.    HORN,    M.  D. 

The  generic  characters  of  Polyphj/lla  have  been  so  often  given  that 
it  is  unnecessary  to  repeat  them  here.  In  the  "  Check  List,"  Mr.  Crotch 
has  separated  our  species  from  those  of  Europe  under  the  name  of 
31acraiwxia,  but  no  reason  is  apparent  to  me  for  such  a  course. 

The  males  are  much  more  abundantly  found  than  the  females  the 
latter  rarely  flying,  while  the  males  are  often  seen  circling  in  flight  in 
considerable  numbers  over  the  spot  where  the  female  may  be. 

As  the  "males  are  the  more  abundant  and  as  they  present  structural

Occurs  in  Kansas  and  northern  Texas.  For  a  specimen  of  the 
female  which  seems  to  be  rare,  I  am  indebted  to  Prof.  F.  H.  Snow 
of  Kansas. 

P.  cavifrons  Lee,  Proc.  Aead.  1854,  p.  222;  Journ.  Acad.  1856,  p.  228.— 
Clypeus  truncate  in  front,  margin  moderately  reflexed,  angles  not  prominent. 
Front  flat  coarsely  punctured  and  with  few,  short,  semi-erect  hairs.  Thorax  with 
very  few  erect  hairs  in  front,  surface  sparsely  clothed  with  scale-like  hairs  which 
are  denser  in  the  median  sulcus,  lateral  vittse  indistinct.  Elytra  sparsely  clothed 
with  scale-like  hairs  forming  a  subvittate  appearance.  Body  beneath  with  moder- 
ately long  hairs,  abdomen  with  elongate  scales  sparsely  placed.  Length  .96  inch; 
24  mm. 

Male. — As  in  the  preceding  species. 

Female. — Unknown. 

This  species  could  be  confounded  with  the  preceding  only.  It  has  a 
somewhat  more  robust  facies  and  diflPers  in  the  form  of  the  clypeus  and 
the  surface  vestiture. 

My  specimen  was  collected  at  Ehrenberg,  Arizona ;  those  in  Dr. 
Leconte's  cabinet  are  from  an  uncertain  locality  in  the  same  Territory. 

P.  deceniliiieata  Say,  Journ.  Acad,  iii,  p.  246;  Lee.  loc.  cit.  1856,  p.  229. — 
Clypeus  trisinuate,  sometimes  feebly,  the  angles  distinct.  Vertex  flat  with  few, 
short,  semi-erect  hairs,  densely  scaly  at  the  sides.  Thorax  with  a  few  erect  hairs 
along  the  margin  only,  surface  sparsely  clothed  with  white  scales,  forming  a  denser 
vitta  in  the  median  impression  and  on  each  side.  Seutellum  densely  scaly.  Elytra 
scaly,  the  suture  three  nearly  entire  vittse  and  a  short  subhumeral  line  densely 
clothed  with  white  scales,  the  remainder  of  the  surface  sparsely  clothed  with  scales 
which  are  often  yellowish.  Pygidium  rather  densely  clothed  with  narrow  elongate 
scales.     Body  beneath  as  in  Hammondi.     Length  .96 — 1.44  inch  ;  24 — 36  mm. 

Male.—  Antennse  as  in  Hammondi.  Anterior  tibite  bidentate.  Middle  and  pos- 
terior tibise  with  one  short  spine  a  little  below  the  middle. 

Female. — Anterior  tibiae  tridentate,  middle  and  posterior  each  with  two  short 
spines  on  the  outer  edge.  Antennal  club  5-lamellate,  a  little  longer  than  half 
tbe  stem. 

Specimens  occasionally  occur  in  which  the  vittae  are  somewhat  irregular 
or  interrupted. 

Occurs  from  Colorado  westward  to  California. 

P.  Ci'iiiita  Lee,  Journ.  Aead.  1856,  p.  2.30.— Very  closely  resembles  the  pre- 
ceding sj)eeies  and  differs  in  having  moderately  long,  erect  hairs  on  both  the  head 
and  thorax.  The  latter  has  the  usual  scales  replaced  by  very  narrow  scale-like 
hairs,  even  the  three  vittpe  can  hardly  be  called  scaly.  On  the  elytra  the  scales 
are  also  more  liair-like  while  they  form  a  style  of  ornamentation  resembling  that 
of  denemlineatn.  Length  .88 — 1.04  inch;  22  -26  mm. 
Sexual  characters  as  in  decemhneata. 

This  species  appears  to  bear  the  same  relation  in  the  matter  of  vesti- 
ture to  the  preceding  that  cavifrons  does  to  Hamwondi.

on  the  middle  and  posterior  tibise,  and  the  anterior  tibiee  are  bidentate  as  in 
the  male. 

Thi.s  species  is  the  only  one  in  wliicli  the  anterior  tibia?  are  known 
to  be  similarly  dentate  in  the  two  sexes. 

Occurs  near  the  sea  coast  in  the  Southern  States,  my  specimens  are 
from  near  Wilmington,  N.  C.  The  females  are  said  to  be  more  abundant

Notes  on    EI^ATERID^.    CEBRIOIVID^.,    RHIPICERID^ 
and  OASCYLLID^. 

BY    GEORGE    H.    HORN,    M.  D. 

ELATERID.5;. 

The  genera  of  the  above  family  to  which  especial  reference  is  made 
in  the  following  pages,  are  those  considered  most  closely  allied  to  the 
Cebrionidae,  so  close  in  fact  that  they  may  be  considered  as  entirely  filling 
the  gap  which  has  been  supposed  to  exist  between  the  two  families. 

The  notes  are  necessarily  short,  full  descriptions  of  the  males  having 
already  been  given,  the  females  as  far  as  known  claim  more  attention 
and  it  is  hoped  that  the  accompanying  figures  will  give  a  better  idea  of 
these  remarkable  insects  than  description  alone. 

The  females  of  Apla.^tus  and  Eufh^sariius  are  remarkable  in  having 
the  elytra  shorter  than  the  abdomen,  but  not  equally  so  in  all  as  will  be 
seen  by  an  examination  of  the  figures. 

In  the  former  genus  there  are  but  six  visible  ventral  segments  while 
in  Eiitliiji^ninnx  there  are  seven.  In  the  9  of  E.  lautus  however,  the 
abdomen  is  so  extended  by  the  completeness  of  the  egg  development, 
that  the  membranous  segment  which  is  usually  subcoxal  becomes  visible 
and  eight  segments  appear.  In  all  the  females  there  is  a  similarity  on 
the  dorsal  surfiice  of  the  abdomen,  eight  segments  being  quite  distinctly 
visible.  Nor  is  this  number  peculiar  to  the  female,  the  male  having  the 
same  but  the  segments  are  more  membranous.  In  an  examination  of 
several  other  true  Elateridas  the  number  of  dorsal  segments  is  eight, 
therefore  the  presence  of  this  nvimber  in  the  females  of  Euthijudnius  and 
ApldstiiR  must  be  dismissed  from  the  category  of  remarkable  characters. 

APHRICUS  Lee. 
Fnmt  slightly  concave,  anterioi'ly  slightly  arcuate,  margined.  Labrum  short, 
transverse,  emarginate  and  retracted,  the  suture  distinct.  Mandibles  moderately 
prominent  and  toothed  a  little  in  front  of  middle.  Maxillary  palpi  rather  slender, 
the  last  three  joints  subequal,  the  terminal  very  little  broader  at  tip.  Antenna? 
sknuler  not  serrate,  two-thirds  as  long  as  the  body,  eleven-jointed,  last  joint  with 
a  distinctly  articulated  short  accessory  piece,  first  joint  obconical,  slightly  curved,

second  small,  third  a  little  longer,  fourth  as  long  as  first,  4 — 11  gradually  more 
elongate.  Eyes  rather  large,  round  and  prominent.  Tarsi  slender,  first  joint  on 
each  foot  shorter  than  the  second  and  about  equal  to  the  fourth. 

A.  californicus  Lee. — Pieeo-testaceous,  sparsely  clothed  with  greyish  pubes- 
cence. Head  coarsely  and  densely  punctured.  Thorax  a  little  longer  than  wide, 
sides  in  front  arcuate,  posteriorly  slightly  sinuate,  lateral  margin  rounded  without 
limiting  edge,  hind  angles  slightly  divergent  and  with  an  extremely  fine  carina, 
surface  sparsely  punctate  in  front  and  nearly  smooth  posteriorly.  Elytra  striate, 
striae  with  coarse  and  deep,  closely  planed  punctures,  intervals  finely  punctulate, 
the  fifth  subcarinate  at  apical  third.  Body  beneath  very  sparsely  punctulate. 
Length  .24  inch ;  6  mm.     Tl.  II,  fig.  6. 

Of  this  insect  we  know  the  male  only.  The  femtile  probably  does  not 
differ  greatly.     The  general  aspect  is  that  of  an  elongate  Cardiophorus. 

Occurs  from  San  Diego  to  Owen's  Valley,  California ;  but  very  rare. 

APL.ASTUS  Lee. 
The  species  have  been  so  recently  the  subject  of  a  review  that  I 
merely  repeat  the  table  given  in  Trans.  Am.  Ent.  Soc.  1874,  p.  24, 
which  applies  to  males  only. 
Third  joint  of  antenna  similar  in  size  and  shape  to  fourth. 

Antennffi  slender,  feebly  serrate,  three  basal  joints  only  pilose ;  sides  of  thorax 
parallel  not  margined,  hind  angles  strongly  divergent.     PL  I,  fig.  9. 

angusticullis  Horn. 
Third  joint  always  much  smaller  than  fourth,  sometimes  globular  never  triangular  ; 
antennae  with  short  erect  hairs. 
Thorax  not  margined. 

Antennfe  strongly  serrate,  joints  2 — 3  very  small,  equal,  together  slightly 
longer  than  half  the  fourth. 

Elytra  scarcely  striate,  thorax  sparsely  punctate teuuirorinis  Horn. 

Elytra  moderately  deeply  striate,  thorax  coarsely  and  moderately  densely 

punctate corynibifoides  Horn. 

Antennee  serrate,  joint  three  more  than   twice  as  long  as  second,  the  two 

together  nearly  as  long  as  the  fourth speratus  Lee. 

Thorax  distinctly  margined,  at  least  near  base. 

Antennae  stout,  strongly  serrate.     PI.  I,  fig.  6 optattis  Lee. 

Antennse  more  slender,  feebly  serrate niolestus  Horn. 

The  body  is  always  fully  winged  in  the  males.  In  all  the  species  the 
constriction  of  the  eleventh  joint  of  the  antennae  near  the  tip  is  quite 
evident  except  in  molestus. 

There  are  but  two  females  known,  one  of  which  belongs  with  reasonable 
certainty  to  sperntus,  the  other  probably  to  optatus.  It  may  be  needless 
to  say  that  the  characters  given  for  the  sexes  (loc.  cit.  p.  26),  are  not 
valid,  they  are  evidently  variations  of  the  male  only. 

A.  speratus  9  Lee— Parallel,  rufo-piceous,  feebly  shining,  sparsely  pubes- 
cent, body  feebly  winged.  Head  moderately  densely  and  coarsely  punctate. 
Antennfe  passing  slightly  the  middle  of  the  thorax,  subserrate,  first  joint  stout,

gradually  decreasing  in  length,  ninth  not  longer  than  second,  tenth  and  eleventh 
longer,  less  serrate,  the  latter  slightly  constricted  at  tip.  Thorax  not  longer  than 
wide,  slightly  broader  at  base  than  apex,  sides  nearly  straight,  hind  angles  feebly 
divergent,  carinate,  surface  not  densely  punctate,  a  feeble  median  line  posteriorly, 
an  oblique  moderately  deep  impression  on  each  side  at  end  of  carina.  Elytra 
about  two  and  a  half  times  the  length  of  the  thorax,  shorter  than  the  abdomen, 
striate,  intervals  alternately  broader,  the  narrower  intervals  slightly  more  convex 
near  the  tip,  surface  moderately  densely  punctulate  and  near  the  tip  somewhat 
wrinkled,  apex  obliquely  prolonged.  Prothorax  beneath  densely  punctured  at 
middle,  sparsely  at  the  sides,  metathorax  sparsely  and  finely  punctate.  Abdomen 
shining,  very  sparsely  finely  punctulate.    Length  .56  inch;  14  mm.    PI.  I,  fig.  8. 

The  maxillary  palpi  in  addition  to  the  normal  four  joints  have  a  small, 
narrow  joint  at  the  end  of  the  fourth.  The  structure  of  the  antenna? 
above  described  is  also  somewhat  abnormal,  and  I  observe  on  one  side 
that  the  eighth  and  ninth  joints  are  connate  and  on  the  other  mobile. 
The  impressions  in  the  thorax  near  the  tip  of  the  carina  are  probably  not 
permanent  in  their  occurrence,  as  I  observe  a  variation  in  this  respect  in 
the  two  females  of  one  Euthi/sanms  before  me. 

The  abdomen  beneath  is  composed  of  six  segments,  the  last  being 
retractile  and  the  first  and  fifth  equal  to  the  two  adjacent  ones.  From 
the  female  of  Euthi/aanius  this  differs  in  having  one  less  segment  to  the 
abdomen  and  one  less  (eleventh)  joint  in  the  antennae. 

The  reference  of  this  female  to  Aplasfus  speratus  is  not  without  a  little 
doubt,  but  from  its  size,  general  aspect,  locality  of  occurrence,  I  think 
the  propriety  of  the  reference  will  be  fully  confirmed  in  the  future. 

One  specimen,  Marin  Co.,  California ;  in  the  cabinet  of  Mr.  Ulke. 

A.  optatus  9- — Similar  in  form  and  sculpture  to  the  preceding  female  but 
with  the  thorax  more  nearly  square  and  much  more  convex.  The  hind  angles 
liave  a  short  carina  and  the  surface  sparsely  punctured  a  little  more  densely  near 
the  anterior  angles.  The  elytra  are  striate,  the  intervals  convex,  the  surface  rather 
densely  punctulate,  and  the  apex  less  prolonged.  Abdomen  as  in  the  preceding. 
Length  .84  inch;  21  mm.     PI.  I,  fig.  7. 

I  refer  this  female  to  optatus  from  its  size  and  the  sculpture  of  the 
elytra,  the  preceding  female  is  referred  to  speratus  from  the  very  distinct 
alternation  of  the  elytral  intervals.  In  this  female  I  do  not  detect  the 
small  appendicular  piece  on  the  tip  of  the  maxillary  palpi  nor  is  there 
that  apparent  deformity  of  the  antennas. 

One  specimen,  in  the  cabinet  of  Mr.  Ulke.  This  is  the  type  of 
Ananiesus  convexiroUis  Lee. 

FL,ASTOCERUS  Lee. 
This   genus   was   originally   described   by  Dr.  Leconte,  (Trans.  Am. 
IMiilos.  Soc.  X,  p.  502),  on  a  species  from  California,  P.  Schaumi'i,  at 
thi'  same  time  remarking  that  a  "  specimen  of  this  insert  was  sent  by 


AMERICAN   COLEOPTERA.  79 

me  to  Dr.  Schauin,  who  pronounced  it  strictly  congeneric  witli  Callir- 
hipis  angulosa  Germ.,  which  forms  the  type  of  the  unpublished  genus 
Plastocerus."  Lacordaire  and,  following  him,  Duval  both  call  angu- 
losa the  type  of  the  genus,  a  position  which  cannot  by  any  means  be 
sustained,  as  Dr.  Leconte  did  not  see  that  species  and  probably  has  not 
even  studied  it  since  that  time. 

This  would  be  a  matter  of  very  little  moment  if  anguloaa  and 
Scliaumii  were  really  congeneric,  of  which  I  have  very  considerable 
doubt  from  the  structure  of  the  labrum  and  the  antennae  and  the  form 
of  the  mandibles.  I  have  not  seen  the  angulosa  and  can  go  no  further, 
and  leave  the  development  of  the  matter  to  European  students. 

Of  our  own  species  I  have  seen  and  studied  many  specimens,  and 
conclude  that  all  the  forms  constitute  but  one  species  in  which  three 
varieties  may  be  indicated. 

Hind  angles  of  thorax  stronglj  divergent  and  earinate. 

Thorax  rather  narrow  not  very  densely  punctured.    PI.  II,  fig.  l...Scliaiiiiiii. 

Thorax  as  broad  as  long,  coarsely  and  densely  punctured.  PI.  II,  fig.  2...1i'siter. 
Hind  angles  not  divergent  feebly  earinate. 

Thorax  narrow  coarsely  and  densely  punctured.     PI.  II,  fig.  3 macer. 

In  the  accompanying  plate  I  have  endeavored  to  represent  the  three 
characteristic  forms  with  the  details  of  sculpture  and  two  additional 
outlines.  There  is  no  constancy  in  the  form  of  the  thorax  nor  in 
the  sculpture  of  the  elytra  all  intermediate  degrees  occurring  in  both 
particulars. 

The  figure  given  of  frater  (PI.  IT,  fig.  2),  is  undoubtedly  a  female, 
and  I  find  no  important  difference  from  the  male  excepting  in  the  struc- 
ture of  the  antennas  and  the  last  ventral  segment.  In  the  antennae  the 
branches  are  about  half  the  length  of  those  of  the  male  and  not  ciliate 
at  the  sides,  and  with  a  few  short  ciliae  at  tip  only.  The  last  ventral- 
segment  is  merely  shorter  and  broader  than  in  the  male. 

If  this  is  really  the  female,  and  I  think  there  is  no  dbubt,  the  species 
shows  a  wide  divergence  from  Euthysanius  in  this  sex,  the  males  of  the 
genera  differing  merely  in  the  number  of  the  joints  of  the  antennae. 

Occurs  in  southwestern  maritime  California. 

In  fig.  4,  will  be  found  an  illustration  of  a  curious  monstrosity  which 
explains  itself. 

EUTHYSANIUS  Lee. 

The  form  of  the  labrum  appears  to  have  no  value  specific  or  otherwise, 

it  may  be  truncate,  sinuate  or  even  triangularly  emarginate  and  in  the 

same  species.     There  appear  to  be  but  two  species  in  both  of  which 

I  observe  an  amount  of  variation  which,  with  fewer  specimens,  would 


80  GEO.    H.    HORN,    M.  D. 

probably  cause  further  subdivision,  but  it  will  be  observed  in  all  these 
aberrant  and  rather  soft  Elateridse.,  that  there  is  a  certain  elasticity  in 
specific  characteristics  which  must  always  be  taken  into  account. 
The  two  species  are  : 

Terminal  joint  of  antennse  decidedly  shorter  than  the  branch  of  the  eleventh ; 

thorax  always  longer  than  wide  at  middle lautus  Lee. 

Terminal  joint  as  long  as  the  branch  of  the  eleventh  j  thorax  usually  as  wide  at 

middle  as  long pretiosus  Lee. 

E.  LAUTUS  S  Lec. — The  accompanying  plate  shows  what  I  consider 
merely  varieties  of  this  species,  and  it  is  well  here  to  remark  that  the 
impressions  in  the  thorax  of  one  form  and  their  absence  in  the  other  is 
not  by  any  means  constant.  The  typical  form  (fig.  1),  is  usually  darker 
in  color  than  the  other,  a  little  stouter  in  form  and  with  the  thorax 
a  little  more  coarsely  punctured.  It  is  possible  that  the  discovery  of  the 
female  will  show  the  variety  (fig.  2),  to  be  a  distinct  species,  and  if  so 
the  female  will  probably  have  elytra  less  short  than  in  the  true  lautus, 
and  more  nearly  squarely  truncate  at  tip.  Length  %  .80 — .92  inch ; 
20—23  mm.     PI.  I,  fig.  1,  2. 

Occurs  at  San  Diego,  San  Luis  Obispo,  Tejon  and  Owen's  Valley, 
California. 

E.  Isintns  f  • — Elongate,  cylindrical,  slightly  depressed,  rufous,  moderately 
shining,  sparsely  pubescent,  feebly  winged.  Head  moderately  densely  and  coarsely 
punctate.  Antennse  passing  slightly  the  middle  of  the  thorax,  serrate,  first  joint 
obconical,  2 — 5  small,  nearly  equal,  not  angulate  in  front,  6 — 11  longer  with  the 
free  angle  becoming  gradually  longer,  twelve  as  long  as  the  branch  of  the  eleventh 
and  slightly  curved.  Thorax  nearly  square,  very  little  narrowed  in  front,  hind 
angles  slightly  divergent  and  carinate,  surface  not  very  densely  punctured  and 
with  a  depression  and  smoother  space  on  each  side  in  front  and  at  middle  pos- 
teriorly. Elytra  very  little  longer  than  wide  conjointly  and  not  extending  beyond 
the  first  dorsal  abdominal  segment,  suture  slightly  separated  the  angle  rounded, 
ajiex  obliquely  truncate  the  outer  angle  rounded,  striae  deep  and  distinctly  punc- 
tate, the  intervals  convex  sparsely  punctate.  Abdomen  with  eight  fi'ee  segments, 
the  last  two  slightly  shorter  than  the  others,  surface  sparsely  and  finely  punctate 
more  densely  on  the  sixth.  Thorax  beneath  coarsely  punctured  at  middle  and 
very  sparsely  at  the  sides.  Metathorax  very  sparsely  punctate.  Abdomen  more 
shining  not  densely  punctate.     Length  1.44  inch;  36  mm.     PL  I,  fig.  3. 

In  the  only  specimen  I  have  seen  which  is  a  fully  impregnated  female 
the  abdomen  is  greatly  extended  even  beyond  what  I  have  shown  in  the 
figure,  the  connecting  membranes  between  the  abdominal  segments  both 
on  the  dorsal  and  ventral  aspects  are  nearly  half  the  length  of  the 
segments  themselves,  the  abdomen  is  thus  extended  so  as  to  equal  very 
nearly  two  and  a  half  times  the  thorax  and  elytra  together.  The  figure 
is  purposely  drawn  with  less  connecting  membrane  showing.     There  are 


AMERICAN   COLEOPTERA.  81 

eight  abdominal  segments  on  the  upper  and  lower  faces,  the  first  ventral 
is  however  entirely  membranous  and  almost  concealed  by  the  coxae. 

The  body  is  not  apterous,  but  the  wings  are  short  and  feeble. 

One  specimen,  Fort  Tejon,  California ;  in  cabinet  of  Dr.  Leconte. 

E.  PRETiosus  %  Lee. — This  species  excepting  the  antennae  has  more 
the  form  of  some  of  our  Asaphes.  The  antennal  character  is  the  only 
constant  one  for  the  separation  of  this  from  lautus.  The  thorax  is 
usually  as  broad  as  long  but  this  is  not  constantly  so.  The  surface  is 
however  less  coarsely  punctured  and  at  base  more  finely  than  in  lautus. 
Length  .72  inch  ;  18  mm.     PI.  I,  fig.  4. 

This  species  is  the  one  referred  to  by  Lacordaire,  ( Genera  iv,  p.  233, 
note),  and  through  the  kindness  of  Mr.  Alexander  Fry  of  London, 
I  have  one  of  the  specimens. 

Occurs  in  the  Coast  Range  region  at  and  north  of  Santa  Barbara. 

E.  pretiosns  9  .—Elongate,  cylindrical,  slightly  depressed,  rufo-testaceous, 
moderately  shining,  very  sparsely  pubescent,  body  feebly  winged.  Head  moder- 
ately densely  punctate,  vertex  slightly  impressed.  Antennfe  slightly  passing  the 
middle  of  the  thorax,  somewhat  variable  in  structure.  Thorax  a  little  wider  than 
long,  anterior  angles  rounded,  sides  very  feebly  arcuate,  hind  angles  slightly 
divergent  and  carinate,  surface  sparsely  punctate  and  with  a  slight  depression 
each  side  at  the  end  of  the  carina.  Elytra  as  long  or  a  little  longer  than  the  head 
and  thorax  and  covering  the  first  two  abdominal  segments,  sides  arcuate,  apex 
slightly  prolonged,  suture  dehiscent,  striate,  striae  not  punctate,  intervals  sparsely 
punctulate.  Prosternum  coarsely  punctate,  the  side  pieces  quite  smooth,  meta- 
sternum  and  abdomen  sparsely  punctulate.  Abdomen  above  very  sparsely  and 
finely  punctulate.     Length  .80—  90  inch ;  20—23  mm.     PI.  I,  fig.  5. 

The  abdomen  has  eight  distinct  segments  on  the  dorsal  aspect  and  but 
seven  on  the  ventral,  the  first  or  subcoxal  segment  not  being  apparent 
here,  probably  from  the  less  extended  condition  of  the  abdomen. 

The  two  specimens  before  me  which  are  without  any  doubt  the  females 
of  £.  pretiosus  Lee,  show  a  slight  amount  of  variation.  The  specimen 
in  my  cabinet  from  which  fig.  5  was  drawn  has  the  thorax  somewhat 
more  convex  and  the  depressions  of  the  thorax  well  marked,  the  elytral 
striae  quite  deep  and  the  intervals  convex.  In  Dr.  Leconte's  specimen 
the  thorax  more  closely  resembles  that  of  the  male,  the  striae  are  feebler 
especially  at  base  and  the  intervals  less  convex. 

The  antennae  show  the  most  important  difierences.  In  my  specimen 
the  penultimate  joint  alone  has  the  anterior  angle  prolonged,  while  in  the 
other  specimen  (fig.  5  a),  this  joint  and  the  three  which  precede  are  acute 
in  front  and  are  about  intermediate  in  structure  between  figure  5  and 
that  of  E.  lautus. 

Two  specimens  froip  the  coast  region  of  Cal.,  south  of  San  Francisco.

CEBRIONID^. 
Our  genera  in  the  books  at  present  are  three  in  number  separated 
as  follows : 

Labrum  entirely  connate  with  the  front Anachilns. 

Labrum  separated  by  a  suture  from  the  front. 

Anterior  tibiae  entire Cebrio. 

Anterior  tibiae  emarginate  externally Scaptolenus. 

In  studying  the  specimens  of  Anachilus  in  the  cabinet  of  Dr.  Leconte 
all  are  without  suture  between  the  labrum  and  front,  of  the  four  in  my 
cabinet,  one  has  a  distinct  suture,  one  less  distinct,  and  two  no  suture 
at  all.  Extending  the  study  to  Cebrio  the  same  thing  happens,  and 
specimens  occur  with  a  very  distinct  and  probably  flexile  suture  to  others 
where  there  is  absolutely  no  trace  whatever,  the  front  and  labrum  being 
perfectly  continuous.  As  there  is  no  other  difference  between  Anachilus 
and  Gehrio  the  former  must  be  suppressed. 

The  species  of  Cebrio  have  been  separated  by  the  form  of  the  labrum 
(emarginate  or  not),  and  maxillary  palpi,  (terminal  joint  equal  to  a  shorter 
than  the  preceding). 

I  have  had  before  me.  about  three  dozen,  perhaps  more  specimens, 
and  besides  observing  that  some  have  the  labrum  and  front  cari- 
nate,  the  labrum  has  the  anterior  margin  arcuate  in  some,  truncate 
in  others  or  emarginate,  and  in  several  deeply  triangularly  incised, 
and  between  all  these  forms  every  interniediate  degree.  The  maxillary 
palpi  moreover  do  not  possess  that  degree  of  difference  in  structure 
which  enables  us  to  separate  species  thereby,  and  I  have  therefore  been 
compelled  to  abandon  both  the  above  mentioned  characters  and  unite 
all  three  species  in  one. 

By  the  suppression  of  Anachi/us  and  the  occurrence  of  one  new,  there 
are  three  species  in  Cebrio  in  our  fauna  as  follows : 

Antennae  distinctly  serrate,  the  terminal  joint  rather  suddenly  constricted  at  tip; 
elytra  distinctly  striate. 

Presternum  between  the  coxfe  extremely  narrow;  mandibles  very  prominent 
not  capable  of  closure  beneath  the  labrum inaiidibiilaris  Lee. 

Prosternum  between  the  coxpe  not  linear;   mandibles  more  robust  and  when 
closed  are  in  great  part  concealed  at  their  base.    PI.  II,  fig.  7...bicolor  Fab. 
Antennae  feebly  serrate,  terminal  joint  not  constricted  at  tip;  elytra  not  striate. 
Mandibles  very  feebly  prominent estl'iatllS  n.  sp. 

In  a  revision  of  the  Cehriomdpe  (Ann.  Fr.  1874,  p.  534),  Chevrolat 
retains  the  generic  name  Selenodon  for  our  species,  but  for  what  reason 
he  docs  not  state  nor  can  I  find  out. 

€'.  l»icj»Ior  Fab. — Upper  side  brownish,  piceous  or  castaneous,  sparsely 
|ml)esccut,  beneath  and  legs  testaceous.  Head  coarsely  and  densely  punctate. 
Thorax   punctured   but  less  densely  than   the  head.     Elytra  moderately  deeply

striate,  striae  coarsely  punctured  especially  near  the  apex,  intervals  slightly 
convex,  densely  punctate.  Length  .48— .80  inch,  .909;  12—20  mm,  22.59. 
PI.  II,  fig.  7. 

The  thorax  is  very  variable  in  shape  and  convexity — usually  nearly 
square  slightly  narrowed  in  front,  sometimes  slightly  transverse,  the  hind 
angles  are  never  strongly  divergent.  The  disc  may  be  either  normally 
convex  or  variously  impressed.  The  mandibles  when  closed  leave  but  a 
small  open  space  between  them  and  the  labrum. 

C  mandibularis  Lee.  (^nacAt7i<s). ^Moderately  elongnte,  fusco-testaceous, 
sparsely  pubescent.  Head  piceous  or  nearly  black,  moderately  densely  punctate. 
Labrum  transverse,  feebly  emarginate,  usually  pale  in  color,  either  connate  with 
the  front  without  suture  or  with  the  suture  more  or  less  distinct.  Mandibles 
slender,  prominent,  and  when  closed  leaving  a  wide  open  space  between  them. 
Antennae  moderately  serrate,  terminal  joint  deeply  constricted  at  tip.  Thorax 
broader  than  long,  sides  moderately  arcuate,  hind  angles  acute,  divergent,  surface 
moderately  densely  punctate.  Prosternum  extremely  narrow  between  the  coxae. 
Elytra  a  little  broader  than  the  thorax,  deeply  broadly  striate,  striae  coarsely 
punctured  especially  near  the  apex,  intervals  densely  punctulate.  Body  be- 
neath paler  than  above  and  moderately  densely  punctate.  Length  .44 — .54  inch  ; 
11— 13.5  mm. 

Of  this  species  we  know  males  only. 

Occurs  in  Florida. 

C  estriatns  n.  sp. — Moderately  elongate,  pale  brownish  testaceous,  finely 
pubescent.  Head  moderately  densely  punctured.  Labrum  transverse,  feebly 
emarginate,  suture  distinct.  Mandibles  rather  short,  when  closed  not  leaving  a 
space  between  them.  Thorax  nearly  square,  sides  feebly  arcuate,  hind  angles 
short,  acute,  divergent,  surface  not  densely  punctate.  Prosternum  very  narrow 
between  the  coxae.  Elytra  a  little  wider  than  the  thorax,  surface  not  striate  but 
densely  punctate  and  with  faint  traces  of  three  discal  costae.  Body  beneath  not 
densely  punctate.     Length  .44  inch;  11  mm. 

The  antennae  are  less  serrate  than  in  the  two  preceding  species  and  the 
terminal  joint  is  not  constricted,  this  character  with  the  absence  of  elytral 
striae  will  serve  to  distinguish  it. 

One  specimen,  Texas. 

SCAPTOI.ENITS  Lee. 

The  species  of  this  genus  which  occur  in  our  fauna  are  from  Texas. 
In  the  Annales  de  la  Societe  Entom.  de  France,  1874,  p.  523,  Chevrolat 
cites  <S.  6r(2^^«^■  from  Texas  ?  and  p.  524,  *S'.  GaUfornicus  from  California, 
while  in  the  list  of  species  p.  509,  both  are  quoted  from  Mexico.  I  have 
no  doubt  that  they  are  really  Mexican. 

Three  species  are  otherwise  known  to  me. 

Last  joint  of  maxillary  palpus  as  long  or  longer  than  the  preceding.     Last  joint

with  upper  tooth  feeble;  legs  pale  brownish  testaceous estriatus  Lee. 

S.  Lecontei  Salle  {femoralis  Lee.) — Piceous,  moderately  shining,  elytra  pale 
eastaneous.  Head  piceous,  deeply  and  coarsely  punctate  and  with  erect  brownish 
hairs.  Thorax  transverse,  narrowed  in  front,  apex  slightly  prolonged  at  middle, 
anterior  angles  rounded,  sides  feebly  arcuate,  hind  angles  long,  slender  and  not 
divergent  from  the  line  of  the  sides,  base  lobed  at  middle,  sinuate  each  side,  surface 
densely  punctate  and  with  erect  brown  hairs.  Elytra  elongate,  gradually  con- 
vergent posteriorly,  dehiscent  at  apical  third,  at  base  gibbous,  surface  moderately 
deeply  sulcate  and  subcostate,  except  at  base  and  moderately  densely  punctulate, 
sparsely  clothed  with  short  pubescence.  Body  beneath  piceous,  clothed  with 
yellowish  hair,  abdomen  less  punctate  and  with  fewer  hairs.  Legs  piceous,  the 
femora  usually  paler.     Length  .64 — .72  inch;  16 — 18  mm. 

Only  males  are  known.  The  anterior  tibiae  have  the  upper  tooth 
strong.  The  antennae  are  serrate.  In  both  the  maxillary  and  labial 
palpi  the  terminal  joint  is  longer  than  the  preceding. 

The  color  of  the  abdomen  varies  from  piceous  to  testaceous,  the  seg- 
ments often  being  piceous  with  the  posterior  edge  of  the  segments  paler. 
In  fully  mature  specimens  the  tibiae  and  tarsi  are  piceous  the  femora 
paler,  even  pale  yellow. 

This  is  the  most  abundant  species  in  Texas. 

S,  estriatns  Lee. — Piceo-testaeeous,  less  elongate  than  Lecontei.  Head  and 
thorax  similar  but  with  shorter  yellowish  hair.  Elytra  gibbous  at  base,  without 
trace  of  striae  or  costse,  surface  moderately  densely  punctate.  Body  beneath  paler 
than  above  and  with  the  legs  luteous.     Length  .56  inch  ;  14  mm. 

The  anterior  tibiae  have  the  upper  tooth  rather  feeble.  In  the  max- 
illary palpi  the  last  joint  is  shorter  than  the  preceding,  the  last  joint  of 
the  labial  is  also  shorter  but  less  distinctly  so  than  the  maxillary. 

Occurs  in  Texas. 

S.  ocreatns  n.  sp. — Piceous,  elytra  testaceous,  femora  yellow.  Head  and 
thorax  piceous,  moderately  densely  punctate,  clothed  with  moderately  long,  erect, 
yellowish  hair.  Elytra  gibbous  at  base,  pale  testaceous,  sutural  and  outer  margins 
near  the  apex  bordered  with  black,  surface  faintly  subcostate  posteriorly  and  not 
densely  nor  coarsely  punctured,  sparsely  clothed  with  very  short  black  pubescence. 
Body  beneath  piceous,  clothed  with  yellowish  hair.  Legs  pitchy  black,  femora 
yellow.     Length  .56  inch;  14  mm.     PL  II,  fig.  8. 

Very  similar  in  form  to  esfriatns^  and  therefore  shorter  and  less 
attenuate  than  Lecontei.  The  ant<?rior  tibife  have  the  upper  tooth  well 
marked.     The  palpi  are  its  in  esfriufiis.

AMERICAN   COLEOPTERA.  85 

I  find  it  impossible  to  place  either  of  the  hxst  two  species  in  any 
of  the  groups  suggested  by  Chevrolat,  the  characters  given  boing  very 
indefinite. 

The  maintenance  of  the  Cebrionidfe  as  a  family  apart  from  the 
Elateridse,  is  rather  the  result  of  universal  agreement  than  from  the 
presence  of  any  good  reasons. 

"  The  principal  differences  between  this  and  the  preceding  family  is  in 
the  greater  number  (sis)  of  the  ventral  segments,  the  well  developed  tibial 
spurs,  the  expansion  of  the  anterior  tibiaa  at  apex,  and  the  close  connection 
between  the  front  and  labrum.  By  the  intermediate  forms  of  the  group 
Plastoceri,  of  the  previous  family,  all  the  differences  except  those  of  the 
anterior  tibiae  become  evanescent ;  and  I  place  the  Cebrionidfe  as  a  distinct 
family,  only  in  deference  to  the  views  of  the  most  distinguished  foreign 
authorities." 

In  the  above  quotation  from  Leconte  (Classification  p.  175),  I  fully 
agree,  and  add  that  between  the  Plastoceri  and  Cebrio  the  dilatation  of 
the  anterior  tibiae  is  a  matter  of  very  little  diff'erence  and  almost  null. 

Chevrolat  seems  more  satisfied  with  his  results : 

"  For  the  family  of  Cebrionites,  I  think  I  have  united  the  elements 
constituting  a  good  classification  and  which  present  the  most  sharply 
defined  characters:  males  notably  different  from  the  females,  winged, 
elongate ;  females  apterous,  short,  stout ;  the  first  having  the  antennje 
slender,  more  or  less  elongate,  flat,  of  variable  form  conical  or  triangular  ; 
the  second  having  these  members  short,  moniliform,  gradually  broader 
externally ;  the  tarsi  filiform  in  the  two  sexes." 

I  have  no  further  criticism  of  this  than  to  refer  the  reader  to  a 
comparison  of  the  males  and  females  of  Aplastus  and  Euthijmnhia. 

From  the  above  extracts,  which  form  the  substance  of  all  that  has 
been  said  in  defence  of  the  retention  of  the  Cebriqnidee  apart  from  the 
Elaieridse,^  it  will  be  inferred  that  there  are  no  characters  at  present 
known  which  will  separate  these  two  families. 

RHIPICERID^. 

This  family  is  represented  in  our  fauna  by  two  genera,  Zemoa  with 
simple  tarsi,  Sandalus  with  lobed  tarsi.  Brachypsectrn  placed  here  by 
Dr.  Leconte  seems  a  veritable  Dascyllide. 

After  a  careful  study  of  the  characters  of  the  family  I  can  find 
nothing  which  will  warrant  us  in  retaining  it  apart  from  the  Dascyllidae. 
The  presence  of  an  onychium  seems  to  be  the  only  character  at  present 
relied  on  and  this  is  present  in  Stenocolus  (Lichas  Ww..),  a  genus  which 
one  would  not  desire  to  separate  from  association  with  Dasvi/Uus.

SANDALUS  Knoch. 
Four  species   are   known  to  occur  in  our  fauna  which  may  be  dis- 
tinguished in  the  following  manner  : 

Tarsi  broad  and  flat,  the  joints  deeply  emarginate,  the  lamellae  long  and  very- 
distinct. 
Thorax  obtusely  subangulate  behind  the  middle.     PI.  II,  figs.  12 — 13.

Thorax  regularly  conical. 

Thorax  densely  punctured  and  op.aque  with  numerous  large  punctures  inter- 
mixed  porosus  Lee. 

Thorax  finely  punctulate  and  somewhat  shining  with  very  few  coarser  punc- 
tures intermixed niger  Knoch. 

Tarsi  rather  slender,  the  joints  feebly  emarginate,  the  lamellfe  small  and  in- 
.    conspicuous. 
Thorax  as  in  niger.     PL  II,  figs.  10—11 califoriliciis  Lee. 

The  sculpture  of  all  the  species  is  similar,  the  head  densely  and 
coarsely  punctured,  thorax  densely  punctured  with  coarser  punctures 
intermixed,  the  latter  less  evident  in  niger.  The  elytra  are  densely 
coarsely  punctured,  the  punctures  arranged  in  irregular  rows,  and  on 
the  disc  are  often  three  faint  costae. 

In  general  form  the  last  three  species  of  the  above  table  are  quite 
similar  as  shown  on  PI.  II,  figs.  10 — 11.  S.  petrophi/us  however  is 
diiferent  in  outline  as  shown  in  figs.  12 — 13. 

In  color  they  vary  in  the  species  from  castaneous  to  nearly  black, 
specimens  occasionally  occurring  with  the  elytra  testaceous.  The  an- 
tennal  flabellum  of  the  male  usually  piceous  is  sometimes  reddish.

ACNEUS  Horn. 

This  genus  was  founded  by  me  on  a  9  in  my  cabinet  which  suggested 
a  form  distinct  from  any  of  the  genera  known.  For  its  characters  I 
could  only  say  that  "  the  prosternum  is  depressed  between  the  coxae,  the 
latter  therefore  more  prominent  than  it." 

The  parts  of  the  mouth  are  very  similar  to  those  of  Ectopria,  which 
it  otherwise  resembles  except  in  the  characters  of  the  male  which  are 
as  follows : 

Male. — Antenna)  with  first  joint  stout,  suddenly  narrowed  at  base, 
second  small,  oval,  third  longer  than  the  first  two  together,  slender, 
slightly  })roa(ler  externally,  fourth  short,  bearing  a  short  branch,  joints

5 — 11  flabellate,  each  joint  bearing  a  long  slender  branch,  those  from 
5 — 8  gradually  longer,  9—11  gradually  shorter.  Tarsal  claws  broadly 
toothed  at  base,  the  anterior  claw  of  each  pair  bifid  at  tip  as  in  Euhria, 
the  two  parts  divergent.     PI.  II,  fig.  14. 

Female. — Antennas  with  joints  1 — 3  as  in  the  male,  4 — 11  short, 
subserrate.     Claws  slender  and  simple  on  all  the  feet. 

For  the  privilege  of  examining  the  male  I  am  indebted  to  the  kindness 
of  Mr.  H.  Ulke  of  Washington.  His  specimen  is  I  belive  from  Oregon, 
showing  a  wide  distribution. 

Several  unimportant  errors  have  been  observed  in  the  "  Revision  of 
Dascyllidae,"  (Trans.  Am.  Ent.  Soc.  vol.  viii,  1880).

BRACHYPSECTRA  Loc. 

In  a  preceding  page  I  have  suggested  the  propriety  of  referring  this 
genus  to  the  Dascyllidge.  The  entire  absence  of  onychium  excludes  it 
from  Rhipiceridae,  and  while  I  have  but  little  faith  in  the  propriety  of 
retaining  the  latter  family  as  distinct,  taking  the  characters  as  we  find 
them  the  genus  goes  better  with  the  Dascyllidae. 

The  anterior  coxae  are  angulate  externally  and  the  trochantin  quite 
distinct.  The  ft-ont  is  however  narrowed  by  the  insertion  of  the  antennaj 
and  the  mouth  is  inferior  as  in  Eubriini,  two  characters  decidedly  at 
variance  with  the  Dascyllini.  I  would  therefore  suggest  a  change  of 
the  table  proposed  by  me  in  a  Revision  of  the  Dascyllidae  (Trans.  Am. 
Ent.  Soc.  1880,  p.  77),  as  follows: 

Antennpe  distant  at  ba.se,  front  not  narrowed. 

Epistoma  prolonged,  etc MAcnoroooNiNr. 

Epistoma  short,  etc Dascyllini. 

Antennas  approximate  at  base,  front  narrowed. 

Labrum  visible,  mandibles  not  prolonged,  mouth  inferior Brachypsectrini. 

The  tribe  thus  suggested  indicates  a  line  of  affinity  between  the  sub- 
family Dascyllidae  and  the  Eubriini,  which  is  otherwise  quite  wanting 
except  through  a  series  of  other  Helodide  genera. 

The  specimens  I  have  studied  appear  to  be  females  only.  The  antennae 
are  formed  in  a  manner  leading  us  to  expect  the  antenna  of  the  S  to 
be  pectinate.     PI.  II,  fig.  15. 


OO  GEO.    H.    HORN,    M.  D.  ^ 

While  on  the  subject  of  the  Dascyllidae  it  might  be  as  well  to  call 
attention  to  Psepheiius,  a  genus  at  present  placed  among  the  Parnidae. 
It  is  provided  with  a  very  large  troehantin  to  the  anterior  coxae,  and 
there  is  an  entire  absence  of  the  prosternal  lobe  which  is  seen  in  all 
the  Parnidae  protecting  the  mouth  beneath.  The  abdomen  is  also 
constructed  on  a  plan  entirely  at  variance  with  the  latter  family  but 
considerably  resembling  many  of  the  smaller  Dascyllidae.  I  do  not 
feel  fully  prepared  to  defend  a  union  of  Psephenus  with  the  Dascyllidae, 
but  merely  to  call  attention  to  the  obvious  disturbance  of  the  otherwise 
homogeneous  structure  of  the  Parnidae  by  retaining  it  there. 

In  a  paper  which  I  hope  to  present  in  the  future  this  genus  will  be 
more  fully  discussed  and  with  it  Lara  also,  which,  though  less  irregular 
in  its  characters,  introduces  an  element  in  the  Parnidae  which  does  not 
seem  to  fully  belong  there.  Having  but  recently  seen  an  absolutely 
perfect  specimen  of  this  insect,  the  amount  of  study  which  I  have  been 
able  to  devote  to  it  is  not  sufficient  to  warrant  a  decided  expression  of 
opinion  either  way.

On  the  genera  of  CARABIDvE  with  special  reference  to  the 
fauna  of  Boreal  America. 

BY    GEORGE    H.    HORN,    M.  D. 

Before  entering  the  subject  of  the  present  essay  it  will  be  useful  to 
consider  some  preliminary  matters  about  which  there  is  still  some  dis- 
cussion and  differences  of  opinion. 

The  Carabidje  forms  one  of  the  members  of  the  Adephagous  series  of 
coleoptera  which  is  readily  recognized  by  the  predaceous  character  of  its 
mouth  parts,  its  slender  antennae  (except  in  Gyrinidae),  pentamerous  tarsi 
and  the  structure  of  the  first  abdominal  segment  which  is  in  all  cases 
divided  or  hidden  by  the  posterior  coxae  in  such  a  manner,  that  it  is 
entirely  lateral,  rarely  appearing  as  a  small  triangular  piece  between  the 
posterior  coxae. 

The  ventral  character  is  an  important  one  and  it  prevails  without 
exception  in  the  entire  series.  If  we  examine  the  Gyrinidae,  however, 
which  the  books  all  agree  in  saying  have  six  ventral  segments,  the  first 
segment  will  be  found  apparently  very  long  and  passing  entirely  across 
the  abdomen  without  interruption  by  the  coxae.  A  more  careful  ex- 
amination will  show  that  this  segment  is  really  composed  of  two  closely 
united,  but  with  traces  of  the  suture  visible  near  the  coxae  as  I  have 
illustrated  on  PI.  Ill,  fig.  9.  The  Gyrinidae  therefore  have  seven  ven- 
tral segments. 

With  an  apparent  exception  thus  disposed  of  the  limits  of  the  ftimilies 
of  the  Adephaga  are  to  be  considered  and  here  is  the  point  where  the 
greatest  diversity  of  opinion  prevails,  especially  with  reference  to  the 
Haliplidae  and  the  two  aberrant  genera  Amphizoa  and  Fe/obim. 

The  Haliplidje  are  placed  by  Lacordaire  in  the  Dytiscidae  rather  under 
protest,  while  subsequent  authors  have  removed  them  in  a  more  or  less 
decided  manner  either  as  a  separate  family  or  sub-family.  In  a  pre- 
liminary sketch  of  a  new  classification  of  Dytiscidae,  ( Comptes-rendus 
de  la  Soc.  Ent.  Belg.  Sept.  4,  1880),  Dr.  Sharp  says:  "I  exclude  the 
Haliplides  from  the  family  and  leave  for  the  Carabophiles  to  decide 
whether  they  should  be  considered  Carabidae  or  form  a  distinct  family." 
They  should  form  a  separate  family ;  my  reasons  will  be  given  hereafter. 
Amphizoa  immediately  concerns  our  fauna.  It  was  originally  de- 
scribed as  typical  of  a  distinct  family  by  Dr.  LeConte,  (Proc.  Acad. 
1853,  p.  227  —  8),  and  notwithstanding  the  opposition  of  Schaum  the 


92  GEO.    H.    HORN,    M.  D. 

same  view  is  maintained  in  the  Classification  of  the  Coleoptera  of  North 
America.  Chaudoir  (Bull.  Mosc.  1872),  says :  "  notwithstanding  the 
opposition  of  many  entomologists,  this  genus  can  be  placed  only  in  the 
vicinity  of  Trachypachya,  as  a  distinct  group." 

Dr.  Sharp  in  the  paper  above  cited  claims  for  Amphizoa  a  place  in 
the  Dytiscidae  in  the  series  Dytisci  comph'cati^  which  have  the  meta- 
sternal  episternum  taking  part  in  the  closure  of  the  middle  coxae.  This 
character  which  I  first  observed  in  Amphizoa  and  illustrated  by  a  figure, 
(Trans.  Am.  Ent.  Soc.  1867,  p.  157),  appears  to  have  caused  Dr.  Sharp 
to  arrive  at  the  above  conclusion.  I  believe  Amphizon  to  be  far  less 
a  Dytiscide  than  a  Carabide. 

The  series  in  which  Dr.  Sharp  places  Pelohius  is  called  Dytixci  frag- 
mentati  which  is  characterized  by  the  less  complex  structure  of  the  outer 
side  of  the  middle  coxal  cavities.  Here  the  same  number  of  pieces  are 
found  which  we  observe  in  the  sub-family  Carabinag,  that  is,  the  meso- 
sternum,  its  epimeron  and  the  metasternum.  These  two  series  of  Dytiscidae 
Dr.  Sharp  very  aptly  compares  with  a  similar  division  of  the  Carabidae 
in  two  series,  in  which  the  D.  fragmentati  represent  the  more  highly 
specialized  Carabinae  and  the  D.  compUcatl  the  Harpalinae.  In  Amphizoa 
and  Peiobius  I  see  two  distinct  types  each  with  a  very  evident  Carabide 
relationship  and  intermediate  between  the  Carabinas  and  Dytiscidae  in 
two  distinct  lines.  The  Carabinas  seem  to  be  a  centre  from  which  the 
other  Carabidae  and  the  Dytiscidae  diverge,  the  former  toward  a  simpler 
the  latter  to  a  greater  degree  of  complication  of  the  coxal  structure. 

Peiobius  was  accepted  by  Lacordaire  and  many  since  as  an  undoubted 
Dytiscide  with  certain  aberrant  characters.  Dr.  Sharp,  while  admitting 
that  it  has  but  little  claim  to  such  a  position,  places  it  at  the  head  of 
that  family  notwithstanding  that  he  says,  "the  Carabide  predominates 
over  the  Dytiscide  in  its  organization."  That  he  acts  thus  with  impartial 
fairness  to  two  very  aberrant  genera,  must  be  admitted,  but  I  hope  to 
show  that  in  all  the  Adephaga  there  exist  characters  of  very  great 
systematic  importance  which  have  been  entirely  overlooked  and  which 
will  define  with  great  accuracy  the  relationship  of  the  various  families. 

It  must  be  evident  to  all  that  there  are  radical  diiferences  in  the 
formation  of  the  under  side  of  the  body  in  the  now  recognized  families 
of  the  Adephagous  series.  Many  of  the  characters  making  up  these 
difi"erences  have  been  made  use  of  by  various  authors  and  they  have 
now  become  the  common  property  of  the  science. 

The  structure  of  the  metasternum  demands  a  new  study  and  here  will 
bo  found   the  important  characters  to  which  I  have  already  referred. 


AMERICAN    COLEOPTERA.  93 

If  we  examine  that  portion  of  the  body  of  a  Cicindelide,  Carabide  or 
HaUpHde,  it  will  be  observed  that  the  metasternum  consists  of  two 
distinct  pieces,  the  anterior  or  that  which  makes  up  the  greater  part  of 
that  member  and  .the  posterior  or  ante-coxal  piece  separated  from  the 
former  by  a  well  marked  suture  extending  entirely  across  the  body. 
This  line  of  separation  has  probably  been  considered  merely  a  matter  of 
sculpture  but  in  some  Carabidae,  especially  the  0  z  ae  n  i  n  i,  the  two 
sternal  pieces  may  be  entirely  separated  by  a  short  immersion  in  a  solu- 
tion of  caustic  potassa.  In  fact  in  these  last  named  insects  I  am  inclined 
to  believe  the  suture  somewhat  mobile,  as  there  is  an  evident  laxity 
of  articulation  in  the  side  pieces  of  the  body  as  well  as  between  the 
meso-  and  metasternum.  The  suture  and  piece  intended  will  be  seen 
on  PI.  Ill,  figs.  1—5. 

In  Amphizoa  and  Pelobius  the  structure  is  entirely  different.  There 
is  but  a  very  small  ante-coxal  piece  with  the  suture  in  front  of  it  very 
indistinct  and  the  posterior  side  truncate  and  not  prolonged  between 
the  coxae  as  will  be  observed  in  the  preceding  families.  This  gives  the 
metasternum  the  appearance  of  being  truncate  behind,  a  form  of  ex- 
pression already  made  use  of  by  various  authors.  This  structure  is 
shown  on  PI.  Ill,  figs.  6 — 7. 

In  the  Dytiscidae  and  Gyrinidae  with  their  short  metasternum  there 
will  be  observed  an  entire  want  of  any  such  structure.  The  ante-coxal 
piece  is  entirely  absent  without  trace  of  suture,  and  the  metasternum  is 
pointed  between  the  coxae.  The  under  sides  of  Di/tiscus  and  Dineutvs 
are  represented  on  PI.  Ill,  figs.  8 — 9. 

The  posterior  cox?e  also  diifer  greatly  in  the  various  families.  In  all 
the  coxae  are  contiguous  except  in  a  comparatively  few  Carabidac,  the 
extent  of  the  contact  varying  greatly  from  a  mere  angular  touching  to 
quite  a  long  edge  of  contact.  In  the  figure  of  Cychrus  (PI.  Ill,  fig.  1), 
the  coxfe  will  be  seen  separated  by  a  small  triangle  of  the  first  ventral 
segment,  Pterostichus  (fig.  2),  and  Morm.nI//ce  (fig.  3),  show  a  mere 
point  of  contact,  while  in  the  other  genera  on  the  plate  the  extent 
01  contiguous  edge  varies,  being  greatest  in  Diveutus. 

The  coxae  reach  the  side  margin  of  the  body,  separating  the  meta- 
sternal  side  pieces  from  the  first  ventral  segment,  in  all  the  families 
excepting  the  Carabidae  and  Cicindelidae.  Track// park// a  of  the  former 
fiimily  makes  an  exception.  With  this  extent  of  the  coxae  externally 
we  have  associated  an  immobility  of  the  coxae,  thus  aff'ording  a  firm 
point  of  support  for  the  hind  legs  required  by  the  mode  of  life  of  all 
the  genera  possessing  it.     The   extent  of  median   contiguity  tends   to 

(19) 


94:  GEO.    H.    HORN,    M.  D. 

give  still  greater  firmness.     Trachypachys  has  the  coxae  as  mobile  as  in 
ordinary  Carabidae,  there  is  however  but  a  short  line  of  median  contact. 

With  the  above  notes  and  the  characters  already  well  known  in  the 
books  an  arrangement  of  the  Adephagous  families  may  be  outlined  in 
the  following  manner : 

Metasternum    with  an   ante-coxal    piece,   separated    by   a  well    marked 
suture,  reaching  from  one  side  to  the  other   and   extending 
in  a  triangular  process  between  the  coxae. 
Antennae  eleven-jointed.     Posterior  coxae  mobile  and  simple.     Habits 
terrestrial. 
Antennae  inserted  on  the  front  above  the  base  of  the  mandibles.

mandibles  and  the  eyes CARABID.^. 

Antennaj   ten-jointed.     Posterior  coxae   fixed   and   with   large   plates 
almost  entirely  concealing  the  abdomen.     Habits  aquatic.

The  above  scheme  seems  to  give  a  division  of  families  in  accord  with 
both  structure  and  habits.  I  have  used  the  expression  "aquatic"  in 
order  that  Amphizoa  might  be  accommodated,  its  habits,  while  sub- 
a(iuatic,  are  by  no  means  "  natatorial."  I  have  already  given  a  sufii- 
ciently  full  account  of  the  habits  of  this  remarkable  insect,  (Proc.  Ent. 
Soc.  Phil,  vi,  p.  289),  and  will  merely  add  in  brief  that  it  acts  precisely 
like  the  Parnida?  and  is  equally  poor  as  a  swimmer,  and  a  very  awkward 
walker  out  of  the  water. 

The  Cicindelidaj,  with  the  exception  of  a  few  genera,  have  the  maxillae 
armed  at  tip  with  a  movable  hook.  This  is  peculiar  to  the  family.  For 
many  years  the  books  have  presented  Trignnodacfyla  of  the  Carabidae 
as  an  exception  and  an  articulated  hook  assigned  to  it.     In  the  discussion 


AMERICAN   COLEOPTERA.  95 

of  the  Ctenodactylini  tliis  will  be  shown  not  to  be  true,  as  illustrated 
by  fig.  70.  I  have  observed  among  the  M  antic  or  ini,  as  represented 
by  Amhlychila,  Omus  and  Manticora,  that  the  posterior  coxse  are  sepa- 
rated, the  intercoxal  process  meeting  the  metasternum  by  an  obtuse 
articulation.     The  other  tribes  have  these  coxae  contiguous. 

In  a  review  of  the  opinions  expressed  by  authors  regarding  other  possi- 
ble members  of  the  Adephagous  series  we  find  the  Paussidae  included  by 
Burmeister  (Mag.  Zool.  1841,  Ins.  pi.  76),  and  the  Rhysodidae  by  Crotch 
(Proc.  Amer.  Philos.  Soc.  1873).  These  must  be  excluded  for  many 
reasons,  more  especially  as  they  fail  to  present  the  ventral  structure  which 
may  be  safely  taken  as  the  key.  If  we  admit  them  there  is  no  reason  why 
some  and  after  them  all  the  Colydiid^e  should  not  be  admitted  and  the 
door  would  be  open  to  much  of  the  Clavicorn  series.  It  must  be  admitted 
however  that  Faunsus  is  the  nearest  approach  of  the  Clavicorn  series  to 
the  Adephaga  the  approximation  in  another  direction  being  through  the 
■  Byrrhida?  and  Parnidfe  with  however  a  very  wide  interval. 

Having  established  limits  for  the  series  as  well  as  for  the  family 
Carabidae,  it  will  probably  produce  a  better  understanding  of  the  subse- 
quent pages  if  the  various  parts  of  the  body  are  reviewed  and  their 
modifications  studied,  so  that  a  correct  idea  may  be  obtained  of  the 
value  to  be  assigned  to  each  change  of  structure. 

CARABIDAE. 

Head. — The  head  is  usually  oval,  rarely  very  broad  (Pasimackm, 
Enceladtis,  Siagona)  or  very  elongate.  In  the  latter  case  the  elongation 
may  be  in  front  of  the  eyes  as  in  Ci/thrus  or  behind  them  as  in  Camonia 
and  Morrnolyce.  The  neck  is  often  suddenly  constricted  and  sometimes 
behind  the  constriction  expandecl  to  a  semiglobular  condyle  which  admits 
of  very  free  motion  of  the  head  in  every  direction.  The  clypeus  is  usually 
narrower  than  the  front  and  more  or  less  prolonged  but  in  the  L  i  c  i  n  i  n  i 
is  not  more  prominent  than  the  sides  of  the  front.  In  DlcrocMle  and 
Zargus  the  central  portion  is  membranous  recalling  the  structure  of  that 
of  Necrophorus. 

The  head  is  provided  with  sette  which  seem  to  be  special  tactile  organs 
and  which  from  their  constancy,  as  well  in  position  as  presence,  have  an 
important  bearing  from  a  systematic  point  of  view.  The  supra-orliital 
setae  may  be  either  two  or  one  in  number  or  even  entirely  wanting  as  in 
the  Pseudomorphinas.  When  there  are  two  setfe  the  anterior  is  situated 
close  to  the  border  of  the  eye  always  in  front  of  the  middle,  the  posterior 
is  at  a  distance  within  the  eye  opposite  the  posterior  margin.     If  one  seta 


90  GEO.    H.    HORN,    M.  D. 

is  present  it  may  be  close  to  the  eye,  usually  it  is  a  little  removed,  it  is 
never  in  front  of  the  middle. 

The  clypeus  also  bears  setae,  usually  one  on  each  side  and  as  a  general 
rule  those  genera  with  two  supra-orbital  setae  have  the  clypeal  seta  situ- 
ated at  the  middle  of  the  side  of  the  clypeus  at  a  slight  distance  from  the 
margin,  while  those  with  one  supra-orbital  have  the  clypeal  near  the  an- 
terior angle.  Rarely  there  are  more  than  one  clypeal  setae  at  the  side,  as 
in  certain  Anisodactylus  while  in  Pelecium  {ci/anipes)  there  is  no  seta 
whatever  it  being  apparently  replaced  by  a  considerable  development  of 
the  outer  seta  of  the  labrum. 

Eyes. — These  organs  are  sometimes  entirely  absent,  the  instances  are 
now  rather  numerous  and  well  known.  When  present  the  form  shows 
but  little  variation  from  the  round  or  oval  form  (see  Ozsenini).  Their 
size  however  varies  greatly  and  with  it  the  prominence,  Siagona  having 
very  small  eyes  and  in  Elaphrm  they  are  large  and  prominent.  When 
the  eyes  are  large  relatively  to  the  size  of  the  head,  whether  unduly 
prominent  or  i^t,  they  approach  very  closely  beneath  the  head  to  the 
edge  of  the  buccal  fissure,  when  small  they  are  distant  from  the  mouth. 
This  seems  to  be  very  useful  systematically  but  has  not  been  made  use 
of  before  the  present  paper.  The  granulation  also  varies  but  I  have  not 
been  able  to  make  use  of  this. 

Antenna. — These  are  always  eleven-jointed,  usually  filiform  or  seta- 
ceous, sometimes  moniliform  or  compressed.  The  form  seems  to  have  less 
value  from  a  systematic  point  of  view  than  the  extent  of  fine  pubescence 
covering  the  surface  of  the  joints.  The  antennae  have  three  kinds  of 
pilosity,  sometimes  all  present  at  the  same  time.  First,  a  dense,  fine, 
short,  recumbent  pubescence  which  is  present  on  those  joints  with  a  fine, 
dense  punctuation  indicating  probably  the  presence  of  a  special  sense 
identical  with  or  resembling  the  sense  of  smell  in  animals  of  a  higher 
organization.  Second,  a  longer  hairyness  diiFusely  scattered  over  the  joints, 
and  finally  stifFer  hairs  around  the  distal  ends  of  the  joints,  these  are 
especially  well  marked  in  Loricera  and  allied  genera.  The  basal  joint  is 
not  at  any  time  very  long  but  in  the  Scarites  and  Dryptini  sufiiciently 
elongate  to  attract  notice,  on  the  anterior  face  of  this  joint  near  the  tip  is 
a  long  seta.  The  extent  to  which  the  pubescence  covers  the  antennae 
has  been  used  by  many  systematists  since  Lacordaire  but  there  are  so 
many  striking  exceptions  within  tribal  limits  that  it  can  only  be  used  for 
separating  tribes  and  never  for  defining  any  higher  groups.  The  surface 
of  the  antennae  is  not  always  uniformly  punctured.  In  those  genera  with 
the  ant(!nnae  at  all  flattened,  one  or  both  sides  have  a  median  smooth 


AMERICAN    COLEOPTERA.  97 

space.  This  is  well  marked  in  the  Helluonini,  Pterostichna  and 
many  Harpalini.  The  number  of  basal  joints  which  may  be  glabrous 
varies  from  two  to  four,  but  in  Trachyj)achys  there  is  no  pubescence 
whatever. 

It  is  extremely  rare  that  the  antennae  are  received  in  well  marked 
grooves  on  the  under  side  of  the  head.  The  Pseudomorphinfe  are 
I  believe  the  only  instance  of  this. 

Labrum. — This  member  varies  greatly  in  form  and  size.  It  is  usually 
transverse  truncate  in  front  or  slightly  emarginate,  ciliate  or  with  four  or 
six  setae  along  the  margin.  It  is  rarely  bilobed  ( Ci/chrua,  Dicrochile, 
Zargus},  sometimes  very  large  and  convex  {Anthid)  or  prolonged  cover- 
ing in  great  part  the  mandibles  {FiricaluK,  etc.).  In  some  genera  the 
marginal  setae  may  be  very  small,  Anthia  or  entirely  wanting,  Macrn- 
chilus  and  other  genera  of  Helluonini. 

Mandibles. — These  are  variable  in  form  and  prominence,  within 
toothed,  serrulate  or  simple.  The  tip  is  usually  acute,  the  left  mandible 
overlapping  the  right.  Sometimes  however  (certain  Harpalini)  the 
mandibles  meet  in  a  pincer-like  manner.  The  outer  side  is  usually  con- 
cave, forming  an  elongate  groove  (called  the  scrobe),  in  which  usually 
beyond  the  middle  is  found  a  puncture  bearing  a  moderate  seta  in 
those  genera  of  riparial  habits  {Nehria,  Bembkh'inn,  Fafrobuf,  JVomius). 
The  presence  of  this  seta  is  extremely  important  in  defining  the  relation- 
ship of  genera  otherwise  obscure  like  Melsenns  and  Cose  in  ia.  The  scrobe 
is,  however,  sometimes  absent  as  in  the  genera  allied  to  Feutagonka. 

Maxill.e. — In  the  present  family  the  inner  and  outer  lobes  are 
always  present  as  will  be  observed  in  the  figures  ( it  will  be  seen  that  the 
outer  lobe  is  absent  in  Dineutus,  151).  The  inner  lobe  varies  somewhat 
in  form,  it  is  usually  hooked  at.  tip,  the  hook  nevei'  articulated.  The  tip 
may  however  be  obtuse  without  hook  as  observed  ifi  Scaritini  (19,  21, 
22),  Promecognathini  (18),  Pterostichini  (45),  Cratocerini 
(107),  Orthogonini  {Anoncopeucus),  Peleciini  (111),  or  more  or 
less  acute,  without  hook  as  in  Glyplus  (133).  The  inner  edge  is  ciliate 
or  spinulose  and  very  rarely  with  anything  approaching  a  tooth.  The 
outer  or  palpiform  lobe  is  biarticulate  (except  in  CoUistus  118,  and 
Amerizus  38),  the  joints  of  variable  relative  length,  the  two  together 
at  least  equal  to  the  inner  lobe,  with  the  single  exception  of  G/yptus  133, 
where  they  are  shorter. 

Of  the  maxillary  palpi  very  little  can  be  said  in  a  general  way. 
The  accompanying  sketches  represent  every  known  variety  of  form. 

The  maxillary  lobes  by  their  differences  above  mentioned  afford  merely

generic  characters,  while  the  form  of  the  last  joint  of  the  palpus  is  used 
to  separate  tribes,  but  it  is  not  a  very  safe  character. 

Mentu^ni. — The  mentum  closes  the  mouth  more  or  less  perfectly 
beneath  usually  allowing  the  outer  side  of  the  maxillae  at  base  to  be  seen. 
It  is  supported  on  a  peduncle  of  the  submentum  the  suture  separating 
them  usually  very  distinct,  rarely  entirely  absent  as  in  Enceladus  26, 
Siagona  31,  Lesitignathus  65,  certain  Trechi  40,  41,  and  the  Pseudo- 
morphinae  147.  The  form  of  the  mentum  varies  but  no  character  of 
systematic  value  has  been  obtained  from  this  excepting  in  the  Scarites 
where  it  is  very  broad,  or  Drypta  76,  from  its  nearly  orbicular  form. 

The  epilobes  of  the  mentum  are  always  present  in  the  Carabidae 
although  much  inflexed  when  the  ligula  is  large  as  in  Pasimachus  19. 
They  vary  greatly  in  size  from  a  narrow  border,  as  is  the  usual  occur- 
rence, to  a  very  wide  piece  as  in  Schizogenius  23.  Their  extremities  are 
often  prolonged  in  an  angle  or  even  an  acute  process  as  in  Anophthalrmis 
40,  or  Ferigona  63.  The  epilobes  have  been  made  use  of  by  Chaudoir 
in  the  Lebiini  {q.  v.)  and  Pogonini,  in  the  former  case  erroneously 
in  the  latter  with  very  little  success. 

The  mentum  is  usually  emarginate,  sometimes  very  feebly  or  even 
Brachylobus  117,  truncate.  At  the  bottom  of  the  emargination  in  very 
many  genera  a  tooth  of  variable  size  and  form  occurs.  The  tooth  is  formed 
in  two  ways.  It  may  be  made  entirely  of  a  prolongation  of  the  middle 
portion  of  the  epilobes,  or  it  may  consist  of  a  process  of  the  body  of  the 
mentum  narrowly  bordered  by  the  epilobes.  This  character  as  well  as  the 
form  of  the  tooth  will  be  found  sufficiently  represented  in  the  sketches. 

As  a  general  rule  when  the  mentum  tooth  is  well  developed  the 
'■  post-dental"  aetse  are  very  small,  often  inconspicuous,  when  the  mentum 
is  dee]>ly  emarginate  and  the  central  portion  of  the  epilobes  membranous 
these  seta3  are  unusually  large  and  conspicuous,  they  are  also  well  de- 
veloped where  the  ligula  is  unduly  exposed  as  in  Migadops  16.  I  have 
but  rarely  represented  these  in  the  figures  for  fear  of  confusing  more 
important  parts  of  the  mouth. 

In  the  emargination  of  the  mentum  we  usually  find  a  connecting 
membrane  which  is  the  basal  support  of  the  ligula,  and  which  varies  in 
extent  in  accordance  with  the  degree  of  extensibility  of  the  ligula." 

Ligula  or  Labium. — It  seems  to  me  better  that  the  latter  name 
should  be  adopted  for  the  entire  organ  as  most  authors  in  speaking  of 
ligula  may  mean  either  the  whole  or  merely  the  central  member. 

The  labium  consists  of  three  parts,  the  central,  usually  corneovis,  piece 
on   each   side  of  which  are  membranous  appendages  called  paraglossfe. 


AMERICAN    COLEOPTERA.  99 

In  every  dissection  I  have  made  the  three  parts  have  always  been 
present,  sometimes  however  very  closely  united  and  corneous  -  as  in 
Helluomorpha  103.  It  seems  unprofitable  to  discuss  the  modifications 
of  the  ligula  and  paraglossae,  their  forms  are  shown  in  the  figures  and 
the  explanations  given  in  the  tribal  headings. 

From  my  own  observations  I  think  the  labium  the  most  unsafe  and 
unsatisfactory  organ  that  can  be  made  use  of  in  classification  and  the 
poor  results  to  be  obtained  from  it  need  no  further  illustration  than 
Lacordaire's  system  of  Carabidae.  When  the  labium  is  used  in  the 
division  of  tribes  into  smaller  gToups  and  genera  we  have  a  microscopic 
subdivision  resulting  which  overwhelms  the  science  in  a  chaos  of  inde- 
finable groups  and  an  infinity  of  genera  which  threatens  the  exhaustion 
of  the  capacity  of  the  classic  languages  for  further  combination. 

A  great  part  of  the  trouble  with  this  organ  seems  to  have  resulted 
from  causes  which  Jacquelin  Duval  so  well  describes,  (Gen.  Col.  Eur.  i, 
p.  34,  note).  When  observed  under  varying  external  conditions  the 
paraglossae  present  rather  diverse  forms.  They  are  often  thin  and 
membranous  and  will  contract  and  expand  with  moisture  and  fail  to 
present  the  same  appearance  when  dry  as  when  wet.  My  own  dissections 
have  been  drawn  while  the  specimens  were  moist,  and  in  the  smaller 
ones,  enclosed  in  a  drop  of  water. 

The  appendages  of  the  ligula,  the  terminal  setfie  of  varying  number, 
seem  useful  in  assisting  the  placing  of  genera  when  properly  subordinated 
to  other  characters,  but  I  think  that  genera  based  solely  on  the  number 
of  these  setae  or  their  position  must  ultimately  fail  of  recognition. 

While  I  do  not  believe  the  ligula  to  possess  the  value  assigned  by 
some  authors  it  may  be  made  useful.  In  some  vast  groujis  like  the 
Pterostichini  and  Platynini  there  is  a  similarity  of  type  which 
one  will  readily  recognize.  There  are  however  important  modifications 
that  need  riot  mislead  if  properly  studied,  Leati'gnafhus  65,  is  one  of 
these.  In  this  the  ligula  and  paraglossae  are  both  well  marked,  the 
former  feebly  corneous,  the  latter  slender  and  long  but  connected  with 
the  central  ligula  by  a  transparent  membrane  which  serves  to  add  strength 
to  the  organ  which  is  at  best  very  weak  and  thin. 

Labial  Palpi. — These  organs  are  usually  similar  in  their  terminal 
joint  to  the  maxillary  palpi,  when  they  differ  it  affords  a  very  useful 
means  of  separating  genera.  It  appears  however  to  have  escaped  notice 
that  the  relative  length  of  the  last  two  joints  to  each  other  is  a  matter 
of  fir  greater  importance  than  has  been  recognized.  The  terminal  joint 
may  be  e([ua\  to  or  longer  than  the  preceding,  or  shorter.     In  the  former 


100  GEO.    H.    HORN,    M.  D. 

case  the  penultimate  joint  is  bisetose  in  front  and  in  the  latter  plurisetose. 
In  the  genera  allied  to'  Oodes  119,  120,  121,  I  have  not  found  any 
setae  except  in  EvoJenes  122,  nor  in  Ch/senius  pensylvanicus  115,  and 
Glyptus  133. 

The  entire  groups  Dryptini,  Grraphipterini,  Anthiini, 
Zabrini  and  nearly  all  the  Harpalini  have  the  penultimate  joint 
plurisetose.  The  same  character  also  occurs  exceptionally  in  other  tribes. 
The  character  seems  to  be  an  important  one  and  has  been  useful  in 
several  of  the  tables. 

Prothorax. — The  form  of  the  thorax  plays  but  a  subordinate  part. 
The  obliteration  of  the  lateral  margin  in  Apotomus  seemed  to  Schaum 
to  be  very  important  but  the  same  occurs  in  several  remote  genera,  as 
Agra  and  Camonia.  The  basal  lobe  by  its  presence  has  been  useful 
in  the  L  e  b  i  i  n  i.  The  special  setae  of  the  side  margin  are  nearly  as 
important  as  those  of  the  head.  In  those  genera  with  two  supra-orbitals 
we  can  safely  expect  two  at  the  side  of  the  thorax  one  being  in  the  hind 
angle,  where  there  is  one  supra-orbital  that  of  the  hind  angle  is  wanting 
except  in  Bradt/ceUiDi  and  some  few  allied  genera.  All  the  Oodini, 
Anthiini,  Grraphipterini,  Cratocerini,  Orthogonini 
and  GIt/ptus  have  no  lateral  setae  that  I  can  discover  nor  trace  of 
punctures  from  which  they  arise. 

ScuTELLUM. — This  is  never  large,  sometimes  entirely  concealed 
( Omophron),  and  in  the  pedunculate  genera  confined  to  the  peduncle. 
Its  form  is  usually  triangular. 

Elytra. — These  organs  by  their  form  play  an  important  part  in  the 
Harpalinje,  in  accordance  with  the  form  of  the  apex  whether  entire,  sinu- 
ate or  trujicate,  also  the  structure  of  the  base  whether  margined  or  not. 
The  internal  phca,  which  will  be  more  fully  explained  further  on,  has 
been  recognized  by  Bedel  in  his  tables,  but  its  full  import  does  not  seem 
to  have  been  recognized.  Its  use  seems  to  be,  to  hold  the  elytra  more 
firmly  together  by  an  interlocking  with  the  margin  of  the  abdomen. 

The  elytral  sculpture  is  of  course  very  variable,  the  normal  form  is 
nine-striate  but  the  stride  in  Cychrus  far  exceed  this  number.  Some- 
times the  eighth  and  ninth  striae  are  confluent  or  nearly  so  as  in  Oodes. 
The  eighth  on  its  outer  side  bears  ocellate  punctures  which  in  very 
recent  specimens  bear  long  setae  as  shown  in  Fsydrus,  (PI.  lY,  fig.  1). 
The  ocellate  punctures  are  wanting  in  our  Panagaeini,  in  Apotomus 
and  many  Carabinfe. 

Prosternum. — The  modifications  of  this  portion  have  proven 
especially    useful    in    the    Carabinae    as    will    be    seen    by    reference   to 


AMERICAN    COLEOPTERA.  101 

the  table.     In  the  Harpalinse  it  is  of  less  importance  generically.     In 
Cydosomns  the  tip  is  much  prolonged  and  acute. 

Anterior  CoxiE. — The  cavities  receiving  these  are  always  closed 
except  in  a  small  number  of  tribes  of  Carabinae.  In  many  cases  the 
positive  determination  of  open  or  closed  cavities  can  only  be  made  by 
separating  the  prothorax. 

Mesosternum. — The  mesosternum  separates  the  middle  coxae  nar- 
rowly, not  often  widely  {Slagona  and  some  Carabinje),  rarely  the  coxal 
cavities  are  confluent  (certain  0  z  a;  n  i  n  i).  In  front  it  is  usually  oblique 
or  nearly  flat,  rarely  protuberant  and  carinate  (some  Carabinae).  The 
side  pieces,  epimera  and  episterna,  by  their  form  and  extent  give  to  the 
division  of  the  entire  family  one  of  its  most  important  characters.  In 
the  first  sub-family  Carabinae  the  epimera  nearly  equal  the  episterna 
in  size  and  reach  the  coxal  caAaty.  In  the  other  two  sub-families  the 
epunera  vary  in  width  but  do  not  reach  the  coxae,  and  in  some  tribes 
are  extremely  narrow,  in  fact  linear  or  even  partly  hidden  externally 
by  the  episterna. 

Mormolyve  is  one  of  the  most  remarkable  exceptions  in  the  entire 
family.  It  is  plainly  by  its  structure  otherwise,  allied  to  the  Truncati- 
penne  series  but  the  mesosternal  epimera  reach  the  coxae ;  nor  does  the 
exception  end  here,  the  metasternal  episterna  also  form  part  of  the  outer 
side  of  the  coxal  cavity,  a  character  otherwise  unknown  in  the  Adephaga 
outside  of  the  Dytisci  complicati  (PI.  Ill,  fig.  3).  This  gives  an  answer 
to  the  closing  lines  of  Dr.  Sharp's  paper.  (Comptes  rendus  Ent.  Soc. 
Belg.  Sept.  1880). 

Metasternum. — This  segment  yields  nothing  of  importance  in  the 
classification  of  the  family,  its  structure  has  given  us  the  means  of 
dividing  the  Adephaga  in  a  satisfactory  manner.  The  side  pieces  are  of 
less  importance  than  those  of  the  preceding  segment,  the  fusion  of  the 
two  pieces  in  one  has  been  made  use  of  but  its  importance  exaggerated. 
I  have  seen  in  the  same  species  the  epimera  free  or  united  with  the 
episterna  without  suture  {Mefrius). 

Posterior  Cox^. — While  it  has  been  observed  that  the  middle 
coxae  are  sometimes  contiguous,  it  seems  to  have  escaped  notice  that 
the  posterior  are  equally  variable.  In  the  vast  majority  of  genera  the 
coxae  are  contiguous  although  at  times  the  contact  is  small  and  produced 
by  a  slight  extension  inward  of  a  small  process  of  the  coxae  as  shown  in 
PI.  Ill,  fig.  2.  The  metasternum  and  abdomen  are  however  completely 
separated,  as  efiectually  as  in  those  genera  in  which  the  contact  is 
'  larger.     This  is  the  form  observed  in  Pterostichini,  Lebiini  and 

(21)

H  a  r  p  a  1  i  n  i.  In  a  comparatively  few  genera  the  coxae  are  plainly 
separated  and  the  small  triangle  of  the  first  ventral  segment  becomes 
visible  between  them.  This  character  is  scattered  in  all  parts  of  the 
series.  In  Brachymis  it  seems  to  lose  its  value  as  species  occur  with 
the  coxse  contiguous  or  separated.  In  Trachypnchys  alone  the  coxae 
externally  reach  the  side  margin  of  the  body.  This  character  is  usual 
in  all  the  following  families  but  unique  here. 

Abdomen. — There  are  always  six  segments,  the  first  lateral.  Their 
length  varies  but  not  to  an  extent  to  afi"ord  systematic  characters. 
In  Brachynus  there  are  said  to  be  seven  or  eight  segments  but  this 
is  sufficiently  discussed  in  that  tribe. 

Each  of  the  first  five  segments  bears  near  its  posterior  edge  and  on 
each  side  of  the  middle  a  puncture  bearing  an  "  ambulatorial  seta." 
The  last  ventral  is  apt  to  vary  sexually  in  its  punctuation  and  the  males 
will  be  seen  to  have  but  one  puncture  each  side  and  the  females  two. 
Other  sexual  modifications  of  the  last  ventral  are  often  observed,  but 
these  have  more  often  a  specific  than  generic  value. 

Legs. — The  only  specially  important  variation  is  found  in  the  anterior 
tibiae  whether  emarginate  or  not  on  the  inner  side  and  with  this  the 
position  of  the  terminal  spurs.  In  some  genera  the  anterior  tibi«  are 
grooved  on  the  inner  side  in  the  axis  of  the  member,  these  have  the 
spurs  of  necessity  terminal.  It  will  be  observed  then  that  the  greater 
the  obliquity  of  the  groove  the  more  one  spur  is  elevated  so  that  when 
the  emargination  is  most  perfectly  developed  the  inner  spur  is  at  the 
upper  angle  of  the  emargination.  The  tibial  spurs  are  always  present, 
sometimes  very  short  {Agra),  or  very  long  {Tetragonoderus),  and  in  the 
latter  genus  finely  serrulate.  There  are  two  spurs,  never  more,  notwith- 
standing the  assertion  to  the  contrary  in  Zahnis. 

Tarsi. — The  feet  are  five-jointed  without  exception,  the  joints  varying 
among  themselves  in  form  and  size,  and  many  times  afford  a  useful  resort 
for  separating  genera.  The  vestiture  of  the  under  side  is  variable  generi- 
cally  and  again  sexually.  The  mode  of  dilatation  of  the  anterior  male 
tarsi  and  the  vestiture  of  the  dilated  joints  whether  squamulose,  papillose, 
pubescent,  spongy  or  spinous,  gives  at  times  the  only  constant  character 
for  the  separation  of  groups  of  genera. 

As  a  rule  the  anterior  tarsi  of  the  male  are  dilated  in  from  two  to  four 
joints  while  it  often  happens  that  the  sexes  can  not  thus  be  separated. 

Ungues. — The  claws  are  more  often  simple  than  otherwise  but 
numerous  instances  occur  in  which  they  are  dentate,  serrate  or  pectinate. 
These  variations  are  useful  for  the  separation  of  genera. 


AMERICAN   COLEOPTERA.  103 

Facies. — Species  of  a  genus  and  genera  of  a  tribe  have  a  greater 
or  less  resemblance  which  affords  to  the  practiced  eye  an  easy  guide  to 
position,  but  there  are  in  many  parts  of  the  series  such  close  repetitions 
of  form  that  this  can  not  be  relied  on.  Tetragonoderus  and  Bembi'dmm, 
Patrohus  and  Nebria,  Di/schirius  and  Apotomus,  Cyclosomus  and 
Omophron,  are  instances  of  this  mimicry.  On  the  other  hand  allied 
genera  will  be  found  presenting  diversity  of  aspect  and  some  may  be 
polymorphic  as  to  their  species,  as  Carabus  and  Ct/chrus. 

With  this  review  of  the  separate  parts  of  the  body  the  preliminary 
portion  of  this  essay  closes.  I  have  purposely  avoided  citing  many 
instances  of  the  occurrence  of  each  character  as  the  genera  are  unknown 
to  most  of  the  students  of  our  fauna  and  our  native  genera  have  been 
cited  when  they  answer  the  purpose. 

The  Carabidie  may  be  divided  in  the  following  manner  into  three 
sub-families : 

Middle  coxal  cavities  not  entirely  enclosed  by  the  sterna,  the  epimcron 

of  the  mesosternum  attaining  the  coxa.      .     .     .      CARABINE. 

Middle  coxal  cavities  entirely  enclosed  by  the  sterna,  the  epimeron  not 

attaining,  the  coxa. 

Head  without  antennal  grooves  beneath  and  with  distinct  supra-orbital 

setae.     Ambulatorial  setae  of  abdomen  usually  well  developed. 

HAR  PALING. 

Head  with  distinct  usually  long  antennal  grooves  beneath  and  without 

distinct  supra-orbital  setae.     Ambulatorial  setae  of  abdomen  feeble 

or  wanting PSEUDOMORPHINJS. 

The  only  exceptions  known' to  me  in  the  structure  of  the  middle  coxal 
cavities  is  in  MormoJjjve^  of  which  mention  has  already  been  made.  The 
0  z  a3  n  i  n  i  and  S  i  a  g  o  n  i  n  i  have  been  considered  exceptions  but  by  care- 
ful preparation  of  specimens  I  have  found  the  coxal  cavities  as  in  the  Harpa- 
linae.    In  the  proper  place  these  matters  will  be  found  more  fully  discussed. 

Sub-Family  CARABINjE. 
.  Middle  coxal  cavities  partially  closed  by  the  sterna  the  intervening  space 
occupied  by  the  mesosternal  epimeron.  Head  with  one  or  two  supra- 
orbital setigerous  punctures.  Sides  of  thorax  usually  with  two  setigerous 
punctures.  Anterior  tibiae  either  entire,  obliquely  grooved  or  emarginate, 
the  spurs  either  both  apical  or  with  the  inner  more  or  less  remote. 

The  tribes  of  this  sub-family  contain  a  less  number  of  genera  than  the 
Harpalinae,  but  of  such  a  specialized  type  as  to  make  it  necessary  to  separate 
them  to  such  an  extent  that  many  of  the  tribes  contain  but  one  genus. 


104  GEO.    H.    HORN,    M,  D. 

The  following  table  gives  in  brief  the  characters  which  separate 
the  tribes :

Tribe  XIV.  Enceladini. 
Posterior  coxse  contiguous. 

Anterior  tibise  emarginate  within,  the  outer  apical  angle  prolonged. 

Tribe  XV.  Scaritini. 

Of  the  above  tribes  ten  are  represented  within  our  faunal  limits  and 
but  one  of  these,  Metriini,  is  peculiar  to  it  a.s  far  as  the  genera  of  the 
sub-family  are  known  to  me. 

It  is  impossible  to   give  these  tribes  a   linear  arrangement  without 


AMERICAN    COLEOPTERA.  105 

violating  some  of  the  affinities  but  the  numerical  sequence  above  seems 
to  be  the  least  objectionable. 

Representatives  of  all  have  been  studied  from  nature  except  Hiletini, 
so  rare  seem  the  species  that  with  all  my  exertion  I  have  been  unable  to 
procure  one  of  them. 

I  can  hardly  allow  the  present  occasion  to  pass  without  expressing  my 
great  sense  of  obligation  to  Messrs.  Bates  and  the  Jansons  of  London, 
Salle  of  Paris,  and  Dr.  Dohrn  of  Stettin,  for  their  ready  response  to  my 
calls  for  rare  and  valuable  material. 

Tribe  I. — Omophroniiii. 

Antennse  slender,  inserted  under  a  slight  frontal  margin,  four  basal  joints 
glabrous.  Eyes  round,  moderately  prominent,  distant  beneath  from  the  buccal 
opening.  Head  deeply  inserted,  with  one  supra-orbital  seta.  Labrum  short, 
emarginate.  Mandibles  not  prominent,  arcuate,  acute  at  tip,  simple  within  or 
slightly  toothed  near  the  base,  outer  side  slightly  concave  with  a  setigerous 
puncture.  Maxillfe  slender,  inner  lobe  hooked  at  tip,  spinulose  within,  outer 
lobe  slender  biarticulate,  palpi  slender  the  last  two  joints  equal.  Mentum  deeply 
emarginate  and  with  an  acute  tooth,  ligula  truncate  and  slightly  broader  at  tip 
and  bisetose,  the  paraglossse  free  at  tip  but  not  longer,  the  palpi  slender,  second 
joint  longer  than  the  terminal  and  plurisetose  in  front.  Thorax  applied  directly 
against  the  base  of  the  elytra,  sides  with  a  single  setigerous  puncture  a  little 
behind  the  middle.  Scutellum  invisible.  Elytra  convex,  margined  at  base,  sides 
narrowly  infiexed  margin  continuous.  Prosternum  rather  widely  separating  the 
coxpe,  prolonged  and  dilated  behind  them  and  completely  covering  the  meso- 
sternum  the  coxal  cavities  closed  behind.  Mesosternum  in  front  vertical  and 
carinate  with  two  fossje  to  receive  the  under  side  of  the  anterior  eoxse.  Meta- 
sternum  short,  epimera  not  distinct,  posterior  coxte  contiguous.  Tibipe  finely 
spinulose  externally,  the  anterior  slightly  broader  to  tip,  within  obliquely  grooved, 
the  inner  spur  above  the  apex.     Tarsi  slender. 

The  males  have  one  or  two  joints  of  the  anterior  tarsi  dihited  and  spongy 
pubescent  beneath. 

One  genus  constitutes  this  tribe,  Omophron,  concerning  which  all 
authors  seem  to  be  in  accord  in  permitting  it  to  remain  alone. 

At  first  glance  the  posterior  coxae  seem  to  be  separated,  but  a  little 
care  will  readily  detect  the  small  laminiform  processes  which  by  their 
meeting  conceal  the  small  remnant  of  the  first  A^entral  segment. 

European  authors  describe  the  ligula  and  paraglossse  somewhat  different- 
ly but  the  figure  given  is  that  which  will  be  found  in  0.  dentatum  Lee. 

The  plurisetose  second  joint  of  the  labial  palpi  is  a  character  of 
extremely  rare  occurrence  in  the  present  sub-family,  it  is  the  usual 
structure  in  Cicindelidse  and  very  constant  in  Dryptini'  and  ITar|)alini 
of  the  sub-family  Harpalinac. 

The  affinities  of  the  present  tribe  are  very  difficult  to  define.  It 
seems  out  of  place   in  any  part  of  the   series.     Specialization  of  type 

TRANS.  AJI.   ENT.  SOC.  IX.  (22)  Air.M-ST.  1  SSI 


106  GEO.    H.    HORN,    M.  D. 

seems  to  be  carried  to  such  an  extreme  in  the  present  sub-family  that 
tribes  may  be  separated  containing  one  or  at  most  two  genera,  except  in 
the  Scaritini  and  possibly  the  Migadopidae  as  defined  by  Chaudoir. 

Tribe  II.— Trachypachini. 

Antennae  moderate,  arising  under  a  distinct  frontal  margin,  the  joints  all 
glabrous  with  a  few  hairs  near  the  tip  of  each,  first  joint  stout  but  short,  third 
very  little  longer  than  the  second.  Eyes  oval,  not  prominent,  moderately  distant 
from  the  buccal  fissure.  Head  deeply  inserted  in  the  thorax,  with  two  supra- 
orbital setse.  Labrum  short,  broadly  but  feebly  emarginate.  Mandibles  stout, 
arcuate,  concave  on  the  outer  side  and  with  a  setigerous  puncture.  Maxillse  with 
inner  lobe  stout,  falciform,  ciliate  and  spinous  within,  outer  lobe  rather  stout, 
with  two  equal  joints,  palpi  stout,  the  second  and  fourth  joints  equal,  the  third 
a  little  shorter.  Mentum  short,  broad,  with  distinct  suture  at  base,  anteriorly 
feebly  emarginate  with  an  emarginate  tooth.  Ligula  broad,  rounded  and  bisetose 
at  tip,  the  paraglossse  membranous,  obtuse  at  tip,  slightly  longer  than  the  ligula, 
the  palpi  short,  the  second  joint  with  one  seta,  in  front,  the  third  elongate-oval. 
,  Thorax  with  three  setigerous  punctures  at  the  sides,  the  first  at  apical  angle,  the 
second  at  middle,  the  third  at  basal  angle.  Body  not  pedunculate,  scutellum 
distinct.  Elytra  not  margined  at  base,  sides  narrowly  inflexed,  margin  not  in- 
terrupted. Prosternum  horizontal  at  tip  prolonged  behind  the  coxae,  the  eoxal 
cavities  open  behind,  prosternal  sutures  indistinct.  Mesosternum  oblique  and  with 
a  carina  in  front  between  two  fossse  which  receive  the  anterior  coxae.  Metasternal 
epimera  invisible,  the  posterior  coxae  contiguous  within  and  reaching  the  side  of 
the  body  separating  the  metasternal  side  pieces  and  the  abdomen.  Legs  not  long, 
femora  stout,  middle  and  posterior  tibiae  spinous  externally,  anterior  tibiae  spinous 
posteriorly,  gradually  stouter  to  tip,  sulcate  and  feebly  emarginate,  the  inner  spur 
above  the  tip. 

The  anterior  tarsi  of  the  male  have  two  joints  feeblj'  dilated  and  spongy 
pubescent  beneath. 

This  tribe  contains  two  genera  Trachypachys  and  Syslolosoma,  the 
former  occurring  in  our  fauna  and  Europe,  the  latter  in  Chili. 

The  characters  above  given  show  such  an  apportionment  of  those 
peculiar  to  the  sub-family,  with  the  addition  of  one  not  found  in  any  of 
the  tribes  of  Carabidas,  that  it  is  difficult  to  say  in  which  direction  the 
affinities  are  most  marked,  but  those  toward  the  Nebriini  and  Elaphrini 
seem  to  be  the  most  evident.  As  in  all  the  other  tribes  of  the  present 
sub-family  the  affinities  seem  to  be  complex,  and  will  appear  stronger  or 
weaker  in  accordance  with  the  standpoint  from  which  we  view  them. 

The  form  of  the  posterior  coxae  is  the  character  more  especially  note- 
worthy in  this  tribe.  These  members  are  not  of  unusual  dimensions  but 
extend  to  the  margin  of  the  body,  their  line  of  contact  with  each  other 
is  also  greater  than  is  usual  in  the  entire  family. 

In  the  Berlin  Zeitschr,  1860,  p.  166,  Schaum  states  that  Trachypachys 
has  three  spurs  to  the  anterior  tibiae,  two  terminal  and  one  above  the 
emargination,  and  on  p.  167  the  same  is  said  of  Metrius.     From  my 


AMERICAN    COLEOPTERA.  107 

own  observation  no  coleopterous  insect  ever  has  more  than  two  spurs 
to  each  tibia  except  by  monstrosity,  consequently  the  above  statements 
are  incorrect. 

Tribe  III.— Cychrini. 
Antennse  slender,  setaceous,  four  basal  joints  glabrous  (two  only  in  Nomarehin) , 
inserted  under  a  feeble  frontal  ridge ;  first  joint  long  and  often  stout,  third  longer 
than  second.  Eyes  round  moderately  prominent,  distant  beneath  from  the  buccal 
opening.  Head  more  or  less  constricted,  with  one  setigerous  puncture  above  the 
eye,  neck  often  semiglobose.  Labrum  deeply  bifurcate.  Mandibles  long  and 
prominent,  arcuate  and  acute  at  tip,  and  at  least  bidentate  within,  and  with  no 
setigerous  puncture  externally.  Ligula  acute  and  bisetose  at  tip,  the  paraglossse 
variable.  Labial  palpi  long,  the  second  joint  elongate,  plurisetose  in  front,  last 
joint  securiform  and  concave.  Maxillae  with  inner  lobe  slender,  hooked  at  tip, 
ciliate  or  spinous  within,  the  outer  lobe  stout  with  the  terminal  joint  longer,  the 
palpi  long  and  slender,  the  last  joint  seeuriform  and  concave.  Mentum  deeply 
emarginate  without  tooth.  Thorax  variable  in  form  with  a  lateral  and  antebasal 
setigerous  puncture.  Body  not  pedunculate,  scutellum  scarcely  evident.  Elytra 
not  margined  at  base,  sides  rather  widely  inflexed,  margin  acute  and  not  inter- 
rupted. Prosternum  usually  not  prolonged  behind  the  coxse  the  tip  obtuse,  the 
coxal  cavities  open  behind.  Mesosternum  nearly  vertical  and  obtusely  carinate 
in  front.  Metasternal  epimera  not'  distinct.  Posterior  coxae  separated  by  a  tri- 
angular process  of  the  abdomen.  Legs  long  usually  slender,  the  femora  usually 
very  feebly  clavate.  Anterior  tibiae  very  slightly  broader  to  apex,  grpoved  within 
near  the  apex,  the  spurs  terminal  but  placed  slightly  obliquely  to  each  other. 
Tarsi  slender,  the  first  joint  long,  the  fourth  entire. 

Anterior  tarsi  usually  dilated  in  the  males  with  a  variable  number  of  joints 
spongy  pubescent  beneath. 

As  above  defined  the  present  tribe  contains  those  genera  included  by 
Lacordaire  excepting  Dumaster  which  Chaudoir  has  properly  removed 
to  the  Carabini.  Probably  misled  by  the  presence  of  Damaster,  Schaum 
has  suggested  the  union  of  the  present  tribe  with  the  Carabini,  but  the 
characters  separating  the  two  are  so  well  marked  and  sharply  defined  that 
they  must  be  retained  as  distinct. 

The  separation  of  the  posterior  coxae  which  seems  to  have  escaped 
notice  here  as  well  as  in  several  of  the  following  tribes  is  a  character 
of  too  great  importance  to  neglect.  It  is  repeated  in  Metritis^  Prome- 
cognathus  and  Enceladus,  but  there  exists  too  wide  an  interval  between 
the  Cychrini  and  these  genera  for  us  to  suggest  any  special  affinity  with 
either  of  them.  With  the  Carabini  the  Cychrini  appear  to  have  the 
closest  relationship. 

Two  genera  form  this  tribe,  both  represented  in  the  United  States. 

Antennae  with  four  basal  joints  glabrous C'yclirus. 

Antennae  with  two  basal  joints  glabrous Noiiiarotiis. 

Cychrus  as  above  defined  is  rather  polymorphic  and   is  capable  of 

division  into  parts  which  rank  rather  as  sub-genera  than  genera.     Those 


108  GEO.    H.    HORN,    M.  D. 

occurring  in  our  fauna  have  been  the  subject  of  a  study  by  me  in  which 
these  divisions  have  been  treated  in  sufficient  detail  (Trans.  Am.  Ent. 
Soc.  1878,  pp.  168—185). 

Two  important  divisions  may  however  be  noticed,  those  in  which  the 
anterior  tarsi  are  similar  in  the  sexes  and  slender,  and  those  with  the 
anterior  tarsi  dilated  in  the  males.  To  the  first  of  these  series  belong 
the  European  species  and  three  in  our  own  fauna  which  occur  west 
of  the  Rocky  Mountains.  Those  with  dilated  tarsi  are  peculiar  to  our 
fauna.  These  two  series  seem  to  bear  the  same  relationship  to  each  other 
that  Damaster  does  to  Carabus. 

In  Nomaretus  and  one  group  of  Cychrus  (Sphseroderus),  the  tip  of 
the  prosternum  is  somewhat  prolonged  and  Chaudoir  holds  the  opinion 
that,  from  this  fact  and  the  more  widely  dilated  tarsi  of  the  male,  the 
group  should  have  generic  value.  I  do  not  see  any  necessity  for  this, 
for  if  we  attempt  to  divide  Ci/chrus  more  than  two  divisions  will  be 
required  and  the  subject  unnecessarily  complicated. 

Tribe  IV.— Carabini. 

Antennre  slender,  with  four  basal  joints  glabrous,  arising  under  a  feeble  frontal 
ridge.  Eyes  round  moderately  prominent  and  distant  beneath  from  the  buccal 
opening.  Head  not  constricted  behind  the  eyes  and  with  one  supra-orbital  setiger- 
ous  puncture.  Labruiii  broad  and  emarginate.  Mandibles  stout,  arcuate,  acute 
at  tip,  concave  on  the  outer  side  and  without  setigerous  puncture.  Mentum  broad, 
emarginate,  with  a  variable  tooth.  Ligula  variable,  the  paraglossse  distinct. 
Maxillse  with  inner  lobe  strongly  hooked,  densely  ciliate  within,  outer  lobe 
stout.  Palpi  moderate  or  long,  .last  joint  of  both  pairs  securiform.  Thorax  with 
a  setigerous  puncture  at  the  side  and  one  also  near  the  posterior  angle.  Body  not 
pedunculate,  scutellum  small.  Elytra  feebly  embracing  the  sides  of  the  body, 
the  lateral  margin  continuous.  Prosternum  horizontal  at  tip  and  prolonged,  the 
anterior  coxal  cavities  open.  Mesosternum  nearly  vertical  and  subcarinate  in 
front.  Metasternal  epimera  invisible,  posterior  coxse  contiguous.  Anterior  tibiae 
gradually  broader  to  tip,  slightly  grooved  within,  the  spurs  terminal  but  placed 
obliquely  to  each  other.  Femora  moderate,  the  anterior  stouter.  Middle  and 
posterior  tarsi  long  and  slender,  the  anterior  shorter. 

In  the  males  the  anterior  tarsi  are  dilated  and  densely  pubescent  beneath,  the 
dilated  joints  variable  in  number,  simple  in  both  sexes  in  Damaster. 

This  tribe  is  composed  of  species  of  at  least  medium  or  even  of  large 
size,  remarkable  for  the  most  part  for  their  beauty  of  form,  color  and 
sculpture.  As  here  defined  it  contains  those  genera  not  of  the  Nebriide 
type  with  the  addition  of  Damaster.  This  latter  genus  as  remarked  by 
Schaum  (Ann.  Fr.  1862,  p.  68),  differs  from  Carabus  merely  in  the 
absence  of  dilated  tarsi  in  the  male.  The  entire  structure  is  so  closely 
that  of  Carabus  and  so  different  from  Cychrus  that  it  seems  almost 
impossil)le  that  Lacordaire  should  have  associated  it  with  the  latter  genus. 


AMERICAN   COLEOPTERA.  109 

I  entirely  agree  with  Chaudoir  (Bull.  Mosc.  1861,  p.  502),  in  placing 

Damaster  in  the  present  tribe. 

Within  our  faunal  limits  but  two  genera  occur  separated  by  the  form 

of  the  third  antennal  joint. 

Third  joint  of  antennae  cylindrical '. CarabilS. 

Third  joint  of  antennse  compressed Calosoma. 

In  their  numbers  of  species  these  genera  in  our  fauna  reverse  that  of 
Europe  where  Carabua  is  far  more  numerous  than  Calosoma,  with  us 
the  latter  genus  has  the  greater  number  of  species  but  the  disparity 
between  the  genera  is  not  so  great  as  in  Europe. 

Tribe  V. — Pamborini. 

Antennse  straight,  moderate  in  length,  arising  under  a  distinct  frontal  margin ; 
first  four  joints  glabrous,  first  joint  slightly  elongate,  third  longer  than  second. 
Eyes  not  large,  moderately  prominent,  distant  from  the  buccal  fissure.  Head 
narrowed  behind  the  eyes  to  a  distinct  neck  and  with  a  single  setigerous  puncture 
over  each  eye.  Labrum  transverse,  deeply  but  broadly  emarginate.  Mandibles 
arcuate,  acute  at  tip,  strongly  dentate  within,  without  setigerous  puncture.  Mentum 
short,  broad,  narrowed  in  front,  broadly  but  feebly  emarginate,  epilobes  narrow 
but  distinct,  mental  suture  distinct.  (Ligula  and  maxillse  not  dissected.)  Labial 
palpi  robust,  the  terminal  joint  longer,  elongate  securiform,  second  joint  without 
setse.  Maxillary  palpi  similar  but  with  the  second  joint  longer  than  the  fourth. 
Thorax  somewhat  narrowed  behind  the  hind  angles  slightly  prolonged,  a  setigerous 
puncture  at  middle  of  sides  another  near  the  hind  angle.  Body  not  pedunculate, 
scutellum  short  and  broad.  Elytra  not  margined  at  base,  lateral  margin  entire, 
sides  moderately  inflexed.  Prosternum  horizontal  and  prolonged  at  tip,  anterior 
coxal  cavities  open  behind.  Mesosternum  nearly  vertical  obtusely  carinate  in 
front.  Metasternal  epimera  indistinct,  posterior  coxEe  contiguous.  Femora  moder- 
ate, the  anterior  slightly  stouter.  Anterior  tibise  broader  to  tip,  the  outer  apical 
angle  prolonged,  deeply  grooved  on  the  inner  side,  the  inner  spur  situated  con- 
siderably above  the  outer.  Tarsi  slender,  the  first  joint  equal  to  the  next  three 
together,  fourth  joint  slender. 

Anterior  tarsi  slender  and  similar  in  both  sexes. 

This  tribe  contains  but  one  genus  peculiar  to  Australia,  Pamborus. 
Lacordaire  has  associated  JVj^ns  with  it,  but  by  what  process  of  reason- 
ing I  have  been  unable  to  determine  and  which  has  been  very  properly 
separated  by  Chaudoir  and  associated  with  Fanagseus.  By  the  open 
anterior  coxal  cavities,  the  form  of  the  mesosternum  and  the  contiguous 
posterior  coxae,  Pamborus  exhibits  a  decided  relationship  with  the 
Carabini,  but  the  structure  of  the  anterior  tibiae  and  the  more  widely 
inflexed  elytra  are  abundantly  sufficient  to  separate  it  as  a  distinct  tribe. 
By  the  latter  character  a  relationship  is  exhibited  with  the  Cychrini  and 
by  the  anterior  tibiae  with  Scaritini.  It  might  also  be  observed  that  the 
structure  of  the  head  above  resembles  Peleciuvi  but  beyond  the  resem- 
blance there  is  no  further  affinity.

Tribe  VI.— Hiletini. 

Antennae  moderate  in  length,  inserted  under  a  well  marked  frontal  plate, 
geniculate,  the  first  joint  elongate,  received  in  repose  in  a  depression  beneath  the 
eyes.  Head  oval,  stout,  with  two  supra-orbital  setae.  Eyes  small  not  prominent. 
Labrum  transverse  feebly  emarginate.  Mandibles  broad,  arcuate  externally  and 
curved  from  above  downwards  and  without  seta  on  the  outer  side,  pluridentate 
within.  Maxillary  palpi  securiform  %  or  triangular  9-  Mentum  broad,  deeply 
emarginate  with  a  large  quadrifid  tooth.  Ligula  elongate,  spatuliform,  rounded 
at  tip,  the  paraglossse  shorter,  linear  and  ciliate,  terminal  joint  of  the  palpus  more 
strongly  securiform  in  the  male.  Thorax  subcordiform.  Elytra  parallel  feebly 
convex.  Presternum  prolonged  at  tip  and  received  in  a  depression  of  the  meso- 
sternum,  anterior  coxal  cavities  open  behind.  Metathoracic  epimera  distinct. 
Legs  moderate.  Anterior  tibiae  entire,  the  spurs  terminal.  Tarsi  short.  Posterior 
coxae  not  contiguous. 

The  first  three  joints  of  the  anterior  and  middle  tarsi  of  the  male  are  feebly 
dilated  and  spongy  beneath. 

The  tribe  contains  but  one  genus  Hiletun  which  is  unknown  to  me  in  na- 
ture, the  above  characters  have  been  obtained  from  the  books  in  great  part, 
to  which  I  have  added  others  kindly  observed  for  me  by  Mr.  H.  W.  Bates. 
The  relations  of  the  tribe,  like  many  others  of  the  sub-family,  are 
complex,  but  on  the  whole  it  seems  better  placed  near  the  Pamborini 
and  Carabini  than  elsewhere. 

Tribe  VII.— Elaphrini. 

Antennae  moderate  in  length,  rarely  longer  than  head  and  thorax,  three  basal 
joints  glabrous,  the  fourth  pubescent  at  tip  or  entirely  glabrous  in  Diachila,  base 
free,  a  slight  ridge  in  Blethisa.  Eyes  round,  usually  prominent,  moderately  distant 
from  the  buccal  fissure.  Front  more  or  less  deflexed,  with  two  supra-orbital  setae. 
Labrum  moderate,  truncate.  Mandibles  stout,  concave  extei'nally,  with  a  setiger- 
ous  puncture,  arcuate,  acute  at  tip.  Maxillae  hooked  at  tip,  ciliate  or  spinulose 
externally,  outer  lobe  slender  biarticulate,  palpi  moderate  in  length,  terminal 
joint  longer  than  the  preceding.  Mentum  emarginate  with  a  bifid  or  emarginate 
tooth,  ligula  free  at  tip,  bisetose,  acute  in  Elaphruf!,  broad  in  the  other  genera, 
paraglossffi  slender  longer  than  the  ligula,  the  palpi  moderate,  the  last  two  joints 
equal  the  penultimate  bisetose  in  front,  except  in  Diachila.  Thorax  variable  in 
form,  the  seta  in  the  posterior  angle  always  present,  the  lateral  absent  in  most 
Elaphrus.  Body  not  pedunculate,  scutellum  distinct.  Elytra  not  margined  at 
base  except  feebly  near  the  humeri  in  Blethisa,  sides  narrowly  inflexed,  margin 
entire.  Prosternum  obtuse  at  tip  not  prolonged  behind  the  coxae,  the  coxal  cavities 
closed.  Mesosternum  not  prominent.  Metasternal  epimera  not  distinct,  the  pos- 
terior coxae  contiguous.  Legs  moderate.  Middle  and  posterior  tibiae  slightly 
spinulose  externally,  the  anterior  obliquely  grooved,  the  inner  spur  above  the 
apex.     Tarsi  slender. 

This  tribe  contains  the  three  genera  quoted  above,  and  I  suspect 
that  some  if  not  all  of  those  placed  by  Chaudoir  in  his  Migadopidae 
should  be  added  unless  the  ligular  structure  is  allowed  to  have  weight 
in  their  separation.  The  affinities  of  the  tribe  are  feeble  except  in  the 
direction  of  the  Nebriini. 


AMERICAN    COLEOPTERA.  Ill 

The  genera  are  separated  in  the  following  manner  : 

Mentum  tooth  large,  nearly  as  long  as  the  lateral  lobes,  emarginate.  Thorax 
without  lateral  seta.  Elytra  with  variolate  fovese,  not  striate. ..Elaplirus. 
Mentum  tooth  short  bifid  at  tip.     Thorax  with  lateral  setigerous  puncture. 

Head  not  suleate,  elytra  with  feeble  striae  of  punctures Diachila. 

Head  with  deep  lateral  grooves,  elytra  striate  with  interstrial  foveiB...Bletliisa. 

Elaphrus. — The  affinities  existing  between  this  genus  and  Opisthius 
have  been  referred  to  in  the  proper  place.  It  is  remarkable  that  the 
lateral  seta  of  the  thoi-ax  is  absent  in  all  the  species  of  this  genus  except 
viridis  Horn,  which  is  the  only  one  in  our  fauna  with  the  thorax  wider 
than  the  head  including  the  eyes.  In  the  larger  species  the  nudes  have 
four  joints  dilated,  in  the  smaller  but  three. 

Diachila. — Two  species  occur  in  our  fauna,  arctica  Gyll.,  common 
to  both  Europe  and  America,  and  mhpolaru  Lee,  from  Hudson's  Bay. 
The  anterior  tarsi  of  the  male  have  four  dilated  and  spongy  pubes- 
cent joints  and  in  mhpolaris  the  middle  femur  has  a  small  tooth  near 
the  base. 

Blethisa. — Four  joints  of  the  anterior  tarsi  are  slightly  dilated  and 
spongy  pubescent  beneath  in  the  male,  and  in  quadricollis  Hald.,  the 
anterior  femora  have  an  acute  tooth  beneath. 

Tribe  VIII.     Loricerini. 

Anteunaj  sleiuler,  base  free,  first  four  joints  glabrous,  first  joint  elongate,  third 
longer  than  second,  joints  2—6  with  long  bristles  in  front.  Eyes  round,  prominent. 
Head  forming  a  distinct  neck  and  with  one  supra-orbital  seta.  Labrum  moderately 
prominent,  arcuate  in  front.  Maiulibles  thin,  curved,  acute  at  tip,  without  setiger- 
ous puncture.  Maxillae  with  a  moderate  foliaceous  expansion  at  base  which  bears 
long  cilise,  inner  lobe  hooked  at  tip,  sparsely  ciliate  within,  outer  lobe  with  slender 
joints,  palpi  slender  the  last  joint  longer  than  the  preceding  and  acute.  Mentum 
moderately  emarginate  with  an  obtuse  tooth,  basal  suture  distinct.  Ligula  not 
prominent,  slightly  prolonged  in  front  and  bisetose,  the  paraglossse  adherent  in 
their  entire  length  and  not  longer,  the  palpi  slender  the  last  two  joints  nearly 
equal,  the  penultimate  bisetose  in  front.  Thorax  transversely  cordate,  with  a 
single  setigerous  puncture  at  the  side  behind  the  middle.  Body  not  pedunculate, 
scutellum  distinct.  Elytra  margined  at  base,  sides  narrowly  intlexed,  lateral  margin 
entire  but  with  a  distinct  internal  plica.  Prosternum  not  prolonged  behind,  the 
anterior  coxal  cavities  closed.  Mesosternum  oblique  not  carinate  in  front.  Meta- 
sternal  side  pieces  distinct  the  suture  between  them  well  marked,  posterior  coxa; 
contiguous.  Legs  slender,  middle  and  hind  tibiae  spinulose  externally,  anterior 
tibise  deeply  emarginate  within,  the  inner  spur  remote  from  the  apex.  Tarsi 
slender. 

The  anterior  tarsi  of  the  male  have  three  joints  rather  broadly  dilated  and 
densely  spongy  pubescent  beneath. 

This  tribe  contains  but  one  genus  Loricera,  in  our  fiiuna,  with 
which  ElUptosoma  Woll.,  a  Maderan  form  has  been  associated.  These 
are  said  to  differ  in  the  absence  of  metasternal  epimera  in  the  former 


112  GEO.    H.    HORN,    M.  D. 

and  their  presence  in  the  latter,  but  in  all  the  specimens  of  Loricera 
I  have  examined  the  suture  between  the  episterna  and  epimera  are 
quite  distinct. 

Associated  for  a  time  with  the  Panagaeides,  Loricera  has  been  properly 
removed  by  Schioedte,  Schaum  and  Chaudoir.  While  it  must  be  con- 
sidered a  member  of  the  present  sub-family  allied  to  the  Elaphrini  and 
Nebriini,  it  presents  two  striking  characters  at  variance  with  all  the  tribes 
of  Carabinae  and  which  approach  it  to  the  Harpalinae,  the  deeply  emar- 
ginate  anterior  tibiae  and  the  presence  of  the  internal  elytral  plica  which 
is  so  well  marked  in  Pterostichini  and  Panagaeini. 

Tribe  IX.— Nebriini. 

Antennje  with  four  basal  glabrous  joints,  inserted  under  a  slight  frontal  plate 
which  is  not  extended  backward  over  the  eyes  in  a  supra-orbital  ridge.  Eyes 
round,  moderately  or  very  prominent,  distant  from  the  buccal  opening  beneath, 
less  however  in  Leistus  and  Notiophilus.  Head  horizontal  (front  deflexed  in 
Opisihius  and  with  two  supra-orbital  setae),  and  with  one  supra-orbital  seta.  Parts 
of  mouth  variable,  mandibles  always  with  setigerous  puncture.  Thorax  usually 
with  a  setigerous  puncture  at  the  side  and  hind  angle,  both  are  absent  in  Opisthius, 
and  the  posterior  in  Leistus.  Elytra  margined  at  base  except  in  Opisthius,  sides 
narrowly  inflexed,  margin  entire.  Prosternum  horizontal  and  prolonged  behind 
the  coxse,  the  cavities  open  behind;  lateral  suture  of  thorax  beneath  normally 
distant  from  the  margin  except  in  Opisthius.  Mesosternum  carinate  in  front. 
Metasternal  epimera  indistinct,  posterior  coxae  contiguous.  Legs  slender,  middle 
and  posterior  tibise  spinulose  or  ciliate  externally.    Tarsi  slender,  ciliate  beneath. 

The  parts  of  the  mouth  are  so  variable  that  I  will  give  in  brief  the 
principal  characters : 

Leistus. — Labrum  prominent,  arcuate  at  tip.  Mentum  feebly  emar- 
ginate  with  a  short  emarginate  tooth.  Ligula  prominent  narrowed  at 
tip  and  then  trifurcate,  bisetose  behind  the  trifurcation,  the  paragloss^ 
short  with  their  tips  free.  Labial  palpi  long  and  slender  the  second 
joint  longer  than  the  last,  without  setae  in  front.  Mandibles  broad, 
explanate  at  the  sides,  acute  at  tip.  Maxillie  with  slender  processes  on 
the  outer  side  of  variable  length  each  bearing  a  stiff  seta  at  its  tip,  the 
palpi  slender.  The  first  three  joints  of  the  anterior  tarsi  of  male  are 
dilated  and  with  squamules  beneath. 

Opisthius. — Labrum  short,  transverse,  more  prominent  at  middle. 
Mentum  moderately  emarginate,  the  tooth  moderately  long  with  nearly 
parallel  sides,  feebly  emarginate  at  tip.  Ligula  small  concealed  behind 
the  mentum  tooth,  narrowed  at  tip,  slightly  bifid  and  bisetose,  the 
paraglossae  slender  arcuate  and  longer  than  it.  Labial  palpi  slender  the 
last  two  joints  nearly  equal,  the  terminal  finely  ciliate  externally,  the 
preceding  bisetose  in  front.  Maxillfe  ciliate  within,  the  palpi  slender. 
Mandibles  rather  stout  arcuate  and  acute  at  tip,  outer  side  not  concave. 


AMERICAN   COLEOPTERA.  113 

Anterior  tarsi  of  male  with  four  joints  feebly  dilated  and  densely  spongy 
pubescent  beneath. 

NoTiOPHiLUS. — Labrum  moderately  prominent  arcuate  in  front. 
Mandibles  stout  not  prominent,  acute  at  tip.  Maxillae  feebly  ciliate 
internally  the  palpi  moderate  the  terminal  joint  but  little  longer  than  the 
preceding.  Mentum  moderately  deeply  emarginate,  the  tooth  notched, 
ligula  prominent,  the  tip  slightly  prolonged  and  bisetose,  paraglossae 
slender,  arcuate,  longer  than  it,  the  palpi  with  last  two  joints  nearly 
equal,  the  penultimate  bisetose  in  front.  The  first  three  joints  of  the 
anterior  tarsi  are  feebly  dilated  and  spongy  pubescent  beneath. 

Nebria. — Labrum  truncate  or  feebly  emarginate.  Mandibles  acute 
at  tip,  not  concave  externally.  Maxillae  ciliate  at  base,  the  palpi  slender 
the  terminal  joint  a  little  longer  than  the  preceding.  Mentum  deeply 
emarginate  with  a  bifid  tooth,  lig-ula  not  prominent  the  tip  truncate  or 
slightly  prolonged  and  bisetose,  the  paraglossae  usually  adherent  in  their 
entire  extent,  sometimes  slightly  free  at  tip,  the  palpi  moderate,  the 
penultimate  joint  bisetose  in  front.  The  anterior  tarsi  of  the  males  have 
three  joints  feebly  dilated  and  pubescent  beneath. 

Pelophila. — Characters  nearly  as  in  Nebria  with  the  last  joint  of 
the  palpi  more  oval.  First  three  joints  of  anterior  tarsi  of  male  rather 
broadly  dilated  and  densely  pubescent  beneath. 

The  above  characters  seem  to  show  the  danger  of  attaching  too  great 
value  to  characters  drawn  from  the  ligula  and  paraglossae  as  a  basis  for 
the  arrangement  of  the  genera  of  Carabidje. 

In  Notiophihis  the  anterior  tibiae  are  very  obliquely  truncate  the 
inner  spur  above  the  apex.  In  the  other  genera  both  spurs  are  terminal 
but  placed  slightly  obli((uely  to  each  other. 

The   genera  which    occur   in  our   fauna   Ijclonging  to   this  tribe   are 
as  follows : 
Front  deflexed,  head  with  two  supra-orbital  setse,  spurs  of  anterior  tibire  terminal. 

Elytra  with  oeellate  fovese,  not  margined  at  base Opistllius. 

Front  horizontal,  head  with  one  supra-orbital  seta.     Elytra  margined  at  base. 

Anterior  tibise  very  obliquely  truncate,  the  inner  spur  above  the  apex.     Vertex 
sulcate Notiophilns. 

Anterior  tibife  scarcely  obliquely  truncate,  spurs  terminal. 

Mandibles  explanate  at  the  sides,  maxillse  at  base  with  spine-bearing  pro- 
cesses  L.eistus. 

Mandibles  stout,  not  explanate,  maxillse  not  appendiculate  and  merely  setose 
at  base. 

Anterior  tarsi  of  male  feebly  dilated Nebria. 

Anterior  tarsi  of  male  broadly  dilated Pelophila. 

In  addition  to  the  peculiarities  already  mentioned  it  might  be  observed 
that  while  all  the  genera  above  mentioned  (except  Nofiophilus),  place 

TItANS.   AM.   ENT.  SOC.   IX.  (24)  AUGUST,  1881. 


114  GEO.    H.    HORN,    M.  D. 

their  antennae  backward  over  the  body  in  a  more  or  less  curved  position 
when  in  repose,  in  Notiophiius  the  antennae  are  bent  down  under  the 
head  and  encircle  the  margin  of  the  eye. 

The  affinities  of  this  tribe  are  more  marked  in  the  direction  of  the 
Elaphrini  than  elsewhere,  and  it  may  be  e.specially  observed  that  all 
those  characters  which  separate  Opisthius  from  the  other  genera  are 
found  in  ElapJirus,  the  ligula  and  paraglossse  of  these  two  genera  are 
also  similar. 

Baron  Chaudoir  (Bull.  Mosc.  1861,  i,  pp.  492  and  502),  separates  the 
above  genera  making  N'otiophilus  a  separate  tribe  and  placing  the  others 
as  a  sub-tribe  of  Carabini.  If  it  be  considered  advisable  to  divide 
the  above  tribe,  Opisthius  and  Notiophilus  are  equally  worthy  of  repre- 
senting distinct  tribes.  The  union  of  the  tribe  with  Carabini  seems 
to  me  unnatural  from  the  appearance  of  the  genera  as  well  as  from 
their  characters. 

Tribe  X.— Migadopini. 

Autennse  slender,  arising  under  a  slight  frontal  ridge,  four  basal  joints  glabrous. 
Eyes  round,  not  prominent,  moderately  distant  from  the  mouth  beneath.  Head 
short,  broadly  oval,  clypeus  distinct  and  with  a  setigerous  puncture  each  side 
distant  from  the  margin,  one  supra-orbital  seta.  Labrum  short,  truncate,  quadri- 
setose  in  front  and  ciliate  at  the  sides.  Mandibles  acute  at  tip,  feebly  arcuate, 
without  setigerous  puncture  externally.  MaxilL-e  arcuate  at  tip,  spinulose  within, 
outer  lobe  biarticulate,  palpi  stout,  the  terminal  joint  somewhat  oval,  obtuse  at  tip. 
Mentum  short  and  broad,  emarginate,  with  a  broad  emarginate  tooth  nearly  as 
long  as  the  lateral  lobes,  ligula  oval,  bisetose  at  tip,  the  paraglossaj  moderately 
broad  and  adherent  in  their  entire  length,  palpi  moderate,  terminal  slightly  longer 
and  truncate  at  tip,  the  penultimate  bisetose  in  front.  Thorax  broad,  hind  angles 
distinct,  no  lateral  setae.  Elytra  slightly  margined  at  base,  sides  narrowly  inflexed, 
margin  continuous.  Prosternum  acute  at  tip  and  prolonged,  concave  beneath  and 
covering  the  middle  of  the  mesosternum,  anterior  coxa?  closed  behind.  Middle 
coxse  moderately  separated,  the  mesosternal  epimera  very  indistinctly  separated 
from  the  episterna  but  attaining  the  coxal  cavity.  Metasternal  epimera  indistinct, 
posterior  coxae  contiguous.  Legs  moderate.  Anterior  tibiae  obliquely  grooved 
within  at  tip,  outer  edge  slightly  spinulose,  the  inner  spur  above  the  apex. 
Middle  and  posterior  tibiae  spinulose  externally,  the  spurs  moderate  in  length. 
Tarsi  moderate  in  length,  the  first  joint  not  longer  than  the  second. 

In  the  specimen  before  me  of  Migadops  (Brachycselus)  virescens 
the  anterior  and  middle  tarsi  of  the  male  have  four  joints  dilated  and 
papillose  beneath. 

Through  the  great  kindness  of  my  friend  jMr.  H.  W.  Bates,  I  have 
been  enabled  to  examine  the  specimen  above  indicated.  I  regret  that 
I  have  been  compelled  to  define  the  tribe  in  a  somewhat  incomplete 
manner  but  there  will  be  no  difficulty  in  assigning  a  place  here  to  those 
genera  whose  affinities  indicate  it. 


AMERICAN    COLEOPTERA.  115 

The  tribe  as  defined  by  Chaudoir  (Bull.  Mosc.  1861,  i,  p.  510),  is 
certainly  composed  of  very  dissimilar  material  and  I  have  removed 
Metrius  to  form  a  distinct  tribe  the  reasons  for  which  will  be  found  in 
the  proper  place. 

The  genera  referred  to  this  tribe  by  Chaudoir  (omitting  Metrius), 
are — Anfarctonomus,  Brachycselus  and  Migadops  from  Tierra  del  Fuego, 
Monolohus  and  Rhytidognathus  from  Chili,  Lissopterus  from  Falkland 
Islands,  and  Heferodactylus  from  Auckland. 

Monolohus  is  remarkable  in  having  the  outer  maxillary  lobe  of  one 
piece  as  in  AmpMzoa. 

The  tribe  seems  very  naturally  to  lead  from  the  Nebriini  to  the 
Metriini. 

Migadops  virescens  Waterh.,  has  considerable  superficial  resemblance 
to  Nehria  virescens  Horn. 

Tribe  XL — Metriini. 

Antennfe  moder.ate  in  length,  straight,  arising  under  a  distinct  frontal  margin; 
first  four  joints  glabrous,  the  first  joint  stouter  but  not  longer  than  the  third,  5 — 11 
subequal,  pubescent.  Eyes  small,  round,  distant  beneath  from  the  buccal  opening. 
Head  with  a  single  setigerous  puncture  over  the  middle  of  each  eye.  Labrum 
short,  feebly  bisinuate.  Mandibles  short,  concave  on  the  outer  side  and  with  a 
distinct  setigerous  puncture.  Mentum  transverse  broadest  at  middle,  deeply  eniar- 
ginate  and  with  a  rather  stout,  bifid  tooth,  epilobes  distinct,  mental  suture  well 
marked.  Ligula  broad,  obtuse  and  bisetose  at  tip,  the  paraglossse  distinct  and 
adherent  in  their  entire  length ;  palpi  rather  stout,  the  last  two  joints  of  nearly 
equal  length,  the  second  bisetose  in  front,  the  third  broader  to  apex  and  truncate. 
Maxillae  with  inner  lobe  rather  short,  distinctly  hooked  at  tip  and  ciliate  internally, 
the  outer  lobe  biarticulate  and  with  equal  joints;  palpi  rather  stout,  the  terminal 
joint  nearly  as  long  as  the  second,  gradually  broader  to  tip  and  obtuse.  Thorax 
transverse,  a  seta  at  point  of  greatest  width  another  in  front  of  the  hind  angles. 
Bases  of  thorax  and  elytra  in  close  apposition,  scutellum  indistinct.  Elytra  not 
margined  at  base,  moderately  inflexed  at  the  sides,  the  margin  acute  and  entire. 
Anterior  coxal  cavities  closed  behind,  prosternum  slightly  prolonged  and  partly 
covering  the  declivous  and  flat  mesosternum.  Femora  moderately  stout,  the 
anterior  scarcely  thicker.  Anterior  tibife  obliquely  grooved  and  emarginate  near 
the  apex,  both  spurs  terminal.  Middle  tibiae  ciliate  externally.  Posterior  coxae 
separated  by  a  rather  broad  triangular  process  of  the  abdomen.  Tarsi  moderate, 
first  joint  longer  than  either  of  the  three  following,  fourth  not  emarginate. 

The  first  joint  of  the  anterior  tarsus  of  the  male  is  rather  broadly  dilated  and 
with  the  second  densely  spongy  pubescent  beneath. 

The  metasternal  side  pieces  of  which  no  mention  is  made  above  are 
sometimes  simple,  that  is,  with  all  trace  of  suture  between  the  episternum 
and  epimeron  obliterated  or  the  suture  may  be  more  or  less  distinct  and 
the  side  pieces  consequently  double. 

The  genus  Metrius  is  the  only  one  known  to  me  wliich  finds  a  place 
in  the  present  tribe.     It  is  a  very  distinct  type  the  affinities  of  which 


116  GEO.    H.    HORN,    M.  D. 

are  not  easy  to  define.  The  posterior  coxae  being  separated  a  relationsliip 
seems  to  be  indicated  with  the  Promecognathini  and  Cychrini,  especially 
with  the  latter  by  the  more  widely  inflexed  sides  of  the  elytra  but  it 
differs  widely  from  either  by  the  structure  of  the  anterior  tibias.  The 
presence  of  a  setigerous  puncture  on  the  mandible  is  a  very  curious 
addition  to  the  other  characters,  as  I  observe  that  this  is  in  nearly  if  not 
quite  all  other  cases  associated  with  riparial  habits  which  cannot  from 
my  observation  be  said  of  Metrius. 

Chaudoir  (Bull.  Mosc.  1861,  i,  p.  510),  places  the  present  genus  in 
his  tribe  Migadopidae,  and  while  but  one  other  genus  of  that  tribe  is 
known  to  me  I  feel  very  safe  in  saying  that  the  present  can  not  be 
allowed  to  take  place  with  it.  In  the  synoptic  table  the  structure 
of  the  metasternal  side  pieces  is  used  for  the  separation  of  Migadops 
( Brachycaelus)  from  Metrhis.  In  the  specimen  of  Mig.  virescens  before 
me  the  met-epimera  are  not  distinct  while  in  Metrius  the  suture  is 
sometimes  visible  and  in  others  not. 

Tribe  XII.— Mystropomini. 

Antennse  arising  under  a  slight  frontal  jilate,  four  basal  joints  glabrous.  Eyes 
small,  round,  not  prominent,  distant  from  the  mouth  beneath.  Head  oval,  with 
two  small  supra-orbital  setse.  Clypeus  rather  large  with  two  small  setigerous 
punctures  each  side.  Labrum  short,  sinuate  in  front  and  plurisetose.  Mandibles 
acute  at  tip,  feebly  arcuate,  toothed  at  middle,  no  setigerous  puncture  externally. 
Maxillae  arcuate  and  acute  at  tip,  spinulose  and  ciliate  internally,  outer  lobe 
biarticulate,  palpi  rather  stout,  the  terminal  joint  longer,  flattened,  broader  ex- 
ternally with  the  tip  rounded.  Mentum  large,  deeply  emarginate  and  with  a 
large  median  emarginate  tooth,  ligula  cuneiform  suddenly  broader  in  front,  the 
tip  slightly  prolonged  in  front  and  sexsetose.  paraglossse  rather  broad,  adherent 
in  their  entire  length  and  obtuse  at  tip,  the  palpi  stout,  terminal  joint  as  in 
the  maxillary.  Thorax  without  marginal  setse.  Elytra  not  margined  at  base, 
(scutellum  indistinct),  sides  rather  widely  inflexed,  margin  entire  not  interrupted." 
Presternum  obtuse  at  tip,  not  prolonged,  anterior  coxal  cavities  closed  behind. 
Mesosternum  narrowly  separating  the  coxse,  the  epimera  indistinctly  separated 
from  the  episterna  but  distinctly  reaching  the  middle  coxal  cavities.  Metasternal 
episterna  short  and  broad,  the  epimera  distinct,  posterior  coxse  separated.  Legs 
moderate  in  length.  Anterior  tibise  deeply  obliquely  grooved  within  the  spurs 
both  terminal.  Middle  tibise  ciliate  with_  short  depressed  hairs  externally  and 
within,  the  outer  edge  of  posterior  tibise  not  ciliate,  the  tibial  spurs  rather  short. 
Tarsi  slender,  the  first  joint  as  long  as  the  two  following. 

The  tarsi  are  said  by  Chaudoir  to  be  similar  in  the  sexes. 

For  a  specimen  of  Mystropomus  subcostatus  Chd.,  the  only  known 
member  of  the  present  tribe,  I  am  indebted  to  Mr.  H.  W.  Bates. 

Of  all  the  genera  which  I  have  studied  this  has  caused  me  the  greatest 
surprise  from  the  position  in  which  it  is  placed  and  which  appears  to  be 
now  accepted  without  (juestion. 


AMERICAN    COLEOPTERA.  117 

Mystropomus  is  now  placed  at  the  head  of  the  tribe  Ozaenini  by 
Chaudoir,  but  the  reasons  why  it  should  not  be  placed  there  are  very 
many.  In  the  discussion  of  that  tribe  will  be  found  the  reasons  for 
removing  it  from  association  with  the  true  Carabin^e.  The  mesosternal 
epimera  do  not  reach  the  middle  cosal  cavities  as  one  can  prove  by 
softening  the  specimens  in  a  solution  of  caustic  potassa  when  the  sutures 
become  evident  and  mere  plications  of  the  surface  obliterated. 

In  Mi/stropomus  however  we  have  a  structure  of  body  resembling 
very  closely  Metrius  not  only  in  the  inflexed  sides  of  the  elytra  but 
their  general  appearance.  The  epimera  and  episterna  of  both  segments 
are  likewise  constructed  on  a  similar  plan  and  the  posterior  coxae  sepa- 
rated. On  comparing  the  form  of  head  and  antennae  and  even  the 
mouth  parts  we  have  a  striking  analogy  with  Metrius.  I  am  disposed 
to  consider  Mi/stropomus^  the  closest  ally  in  every  respect  with  Metrms 
and  with  Migadops  an  intermediate  link  toward  the  Nebriini. 

It  is  remarkable  that  this  genus  should  occur  in  Australia.  Lacordaire 
(Atlas  pi.  5,  fig.  5K  gives  an  illustration  of  the  species  which  might 
however  be  improved. 

Tribe  XIII.— Promecognathini. 
Antennse  slightly  geniculate,  arising  under  a  slight  frontal  margin,  first  four 
joints  glabrous,  the  first  much  larger  and  stouter  than  the  others,  5 — 11  slightly 
compressed  and  finely  pubescent.  Eyes  small  slightly  oval  and  distant  from  the 
buccal  opening.  Head  with  two  supra-orbital  setse,  neck  slightly  broader  behind 
the  eyes.  Labrum  short,  bisinuate.  Mandibles  elongate,  arcuate  and  acute  at  tip 
and  decussating,  not  toothed  within.  M'entura  short,  broad,  broadly  emarginate 
and  with  a  broad  short  tooth,  epilobes  narrow  but  distinct,  mental  suture  distinct. 
Gula  deeply  transversely  impressed  so  that  the  mentura  is  inserted  at  a  right  angle 
to  the  peduncle.  Ligula  moderately  prominent  narrower  and  free  at  tip,  truncate, 
with  two  setae,  paraglossse  long,  rather  slender  and  ciliate  within  at  the  tip. 
Maxillae  with  inner  lobe  slender  and  long,  obtuse  at  tip,  densely  ciliate  within, 
outer  lobe  biarticulate  the  terminal  joint  much  shorter.  Maxillary  palpi  moder- 
ately long,  the  second  joint  equal  to  the  next  two  together,  terminal  joint  broader 
at  tip  truncate  and  twice  the  length  of  the  third.  Labial  palpi  with  the  last  two 
joints  about  equal  in  length,  the  terminal  broader  at  tip  and  truncate,  the  pre- 
ceding bisetose  in  front.  Thorax  narrowed  at  base,  sides  narrowly  inflexed,  lateral 
margin  distinct,  a  setigerous  puncture  near  the  hind  angle  and  three  at  the  side 
in  front.  Body  pedunculate,  scutellum  invisible.  Elytra  not  margined  at  base, 
lateral  margin  distinct  and  entire,  sides  narrowly  inflexed.  Anterior  coxal  cavities 
closed  behind,  prosternum  not  prolonged,  mesosternum  declivous.  Metasternal 
epimera  indistinct.  Femora  stout,  the  anterior  more  strongly  clavate.  Anterior 
tibire  gradually  broader  to  tip,  smooth  externally,  deeply  emarginate  internally, 
the  inner  spur  remote  from  the  tip.  Posterior  coxae  separated  by  a  triangular 
process  of  the  abdomen  which  meets  the  metasternum.  Tarsi  moderate,  the 
posterior  longer,  first  joint  moderately  long,  fourth  slightly  emarginate.  Tarsi 
similar  in  the  sexes.

The  above  characters  which  I  have  drawn  entirely  from  our  only 
representative  should  be  somewhat  modified  by  the  omission  of  the 
descriptions  of  the  palpi  and  other  parts  which  may  be  considered  purely 
generic.  The  description  is  rather  detailed  in  order  that  the  omissions 
in  previous  descriptions  of  Promecognathux  may  be  supplied. 

This  tribe  as  typified  by  our  genus  has  been  the  subject  of  some 
discussion  and  very  diverse  opinions  have  been  expressed  regarding  its 
systematic  position.  From  my  own  study  I  feel  convinced  that  the  views 
expressed  by  LeConte  (Class.  Col.  N.  A.  p.  12),  are  correct. 

As  far  as  known   to   me  two  genera  only  belong  to   this  tribe,  as 

follows : 

Last  joint  of  maxillary  palpi  oblong-oval  truncate Proinecogitatlius. 

Last  joint  of  maxillary  palpi  strongly  securiform Axiiiiclium. 

These  two  genera  are  placed  by  Lacordaire  (Genera  i,  p.  247),  in  a 
tribe  which  owes  its  origin  to  Chaudoir,  (Bull.  Mosc.  1846,  p.  511), 
composed  as  very  justly  observed  by  Schaum  (Berl.  Zeitschr.  1860, 
p.  178),  of  very  dissimilar  material,  held  together  it  may  be  added  by 
a  bond  of  the  feeblest  nature.  The  positions  of  the  other  genera  will 
be  discussed  in  their  proper  places  and  the  correctness  of  Schaum 's 
views  shown  except  as  to  Glyptu^^  which  has  very  little  to  do  with  the 
Orthogoniens  but  far  more  with  the  Harpalini. 

As  restricted  above  the  tribe  falls  very  naturally  between  the  tribes 
which  precede  and  the  Scaritini. 

Promecognathus  occurs  in  California,  Axinidium  in  western  Africa. 

Tribe  XIV.— Enceladini 

Antennae  moderate  in  length,  straight,  arising  under  a  distinct  frontal  margin  ; 
first  four  joints  glabrous,  the  first  joint  stouter  suddenly  narrowed  at  base,  second 
equal  in  length,  3—11  gradually  shorter  and  more  slender.  Eyes  comparatively 
small,  round  and  distant  from  the  buccal  fissure.  Head  with  a  single  setigerous 
puncture  over  each  eye.  Labrum  moderately  prominent,  arcuate  at  the  sides  and 
feebly  emarginate  at  middle.  Mandibles  stout,  arcuate,  a  large  tooth  near  the 
base,  outer  side  deeply  grooved  and  without  setigerous  puncture.  Maxillae  with 
inner  lobe  strongly  hooked  at  tip  and  with  short  spinules  on  inner  edge,  outer 
lobe  stout  biartieulate,  the  palpi  stout,  second  joint  longer  than  the  others,  the 
terminal  broad,  oboval.  Mentum  large  without  distinct  suture  at  base,  broadly 
arcuate  at  the  sides,  deeply  emarginate  and  with  a  moderate  tooth  emarginate 
at  tip,  epilobes  distinct.  Ligula  prolonged  in  a  broad  obtuse  point,  bisetose,  the 
paraglossaj  corneous  and  closely  united  it;  labial  palpi  moderate,  the  terminal 
joint  somewhat  triangular  and  arcuately  truncate  at  tip.  Thorax  broad,  a  seta  at 
the  side  another  in  front  of  hind  angle.  Body  pedunculate,  scutellum  forming 
the  larger  space  of  the  peduncle  above.  Elytra  not  margined  at  base,  the  lateral 
margin  entire  and  very  narrowly  inflexed.  Presternum  obtuse  at  tip,  not  pro- 
longed, the  coxal  cavities  closed  behind.  Mesosternum  broad  convex  and  oblique. 
Metasternal  opimera  indistinct,  the  posterior  coxa;  distinctly  sejtarated  l)y  a  narrow 


AMERICAN   COLEOPTERA.  119 

abdominal  process.  Femora  moderate  and  nearly  equal.  Anterior  tibife  gradually 
broader  to  tip,  grooved  on  the  inner  side  near  the  tip,  the  spurs  nearly  on  the 
same  line  transversely.  Tarsi  moderate  in  length,  the  first  joint  longer,  the  fourth 
not  emarginate. 

The  tarsi  do  not  differ  in  the  sexes. 

As  in  the  other  tribes  of  the  present  sub-family  which  contain  but 
one  or  two  genera,  the  description  of  the  present  is  made  with  con- 
siderable detail  drawn  entirely  from  the  typical  genus,  the  only  one 
known  to  me  in  nature.  In  the  books  Enceladus  is  placed  with  Siagona, 
a  genus  with  which  it  seems  to  have  very  little  relation  except  the  large 
mentum  without  suture  at  base.  Schioedte  and  Chaudoir  have  been 
deceived  by  a  line  of  sculpture  and  have  placed  the  Siagonides  as  a 
whole  in  the  present  sub-family.  I  do  not  find  the  mesosternal  epimera 
attaining  the  coxae  in  Siagona  while  they  do  very  plainly  in  Enceladus. 
Another  character  used  by  Schioedte  is  of  very  doubtful  utility  "  antennse 
scrobicuiis  recipiendse"  the  antennal  grooves  or  scrobes  being  merely  the 
result  of  the  dilated  genal  plates  which  are  variable  within  generic  limits, 
and  have  already  been  made  use  of  by  me  in  separating  the  species  of 
CycTirus  in  subgeneric  sections. 

Not  knowing  Luperca"^  in  nature  I  am  unable  to  say  whether  it 
enters  the  present  tribe  or  not,  should  it  be  as  closely  allied  to  Enceladus 
as  stated  by  Lacordaire  the  two  genera  form  a  very  distinct  type  equal  in 
value  to  the  Metriini  or  Promecognathini  and  with  its  affinities  but  little 
better  marked.  Lacordaire  perceives  relationships  with  the  Oza^nides, 
Galeritides  and  Scaritides,  but  these  entirely  escape  me  except  as  to  the 
last  of  these  tribes,  to  which  there  is  but  little  resemblance  except  in 
external  form.  I  believe  however  it  is  better  placed  near  the  Scaritini 
than  anywhere  else  in  the  series. 

Enceladus  occurs  in  Colombia  and  Gruiana,  Luperco  in  the  East  Indies. 

Tribe  XV. -Scaritini. 

Antennae  moderate  in  length,  inserted  under  a  frontal  plate  with  a  variable 
number  of  glabrous  joints.  Eyes  comparatively  small  very  finely  granulate  and 
distant  from  the  buccal  opening  (Scarites),  or  normally  convex  and  granulate  and 
not  distant  from  the  mouth  (Clivinse).  Head  variable  in  form  and  with  one 
(Scarites)  or  two  (Clivinse)  supra-orbital  setae.  Labrum  short,  emarginate  or 
sinuate.  Mandibles  at  least  moderately  prominent,  without  setigerous  puncture, 
simple  or  dentate.  Maxillse  with  the  inner  lobe  often  obtuse  at  tip,  in  some 
genera  normally  hooked,  ciliate  or  spinulose  within,  outer  lobe  biarticulate  the 
terminal  joint  usually  shorter,  palpi  variable  in  form.  Mentum  emarginate,  often 
deeply,  the  tooth  variable  in  size,  epilobes  narrow,  but  very  wide  in  Schizogenius. 

*  Chaudoir  replaces  this  name  by  Holoscelis  Chd.  For  other  remarks  which 
may  properly  be  read  as  a  supplement  to  the  present  tribe,  the  reader  is  referred 
to  the  Siaffonini. 


120  GEO.    n.    HORN,    M.  D. 

Ligula  either  broad  and  large  (Scarites)  or  small  and  prolonged  (Clivinse)  the  tip 
narrow  and  bisetose,  except  in  Pasimachus  in  which  it  is  but  little  prominent  at 
middle  and  with  the  two  setse  very  closely  approximated,  paraglossse  usually 
slender  and  longer  than  the  ligula,  spinulose  within  in  the  Scarites.  Palpi  moder- 
ate, terminal  joint  variable  in  form,  shorter  than  the  penultimate  (Scarites)  equal  or 
longer  (Clivinse),  the  penultimate  bisetose  in  front  (Clivinise)  plurisetose  (Scarites). 
Thorax  variable  in  form,  hind  angles  rarely  prominent,  side  margin  with  a  setiger- 
ous  puncture  in  the  hind  angle  (Scarites)  or  with  two  lateral  punctures  (Clivinse). 
Body  pedunculate,  scutellum  not  visible  between  the  elytra.  Elytra  rarely  slightly 
margined  at  base,  sides  narrowly  inflexed  margin  entire  except  in  Ardistomis 
where  there  is  a  distinct  interruption  posteriorly  and  an  internal  plica.  Prosternura 
not  prolonged  behind  the  coxae,  the  cavities  closed  behind.  Mesosternum  vertical, 
not  carinate  in  front.  Metasternal  epimera  not  visible  in  Pasimachus,  more  or  less 
distinct  in  all  the  other  genera.  Posterior  coxse  contiguous.  Legs  stout  more  or 
less  fossorial,  the  anterior  femora  especially  stout.  Middle  and  posterior  tibiae 
ciliate  or  spinulose  externally  but  often  very  finely,  anterior  tibise  palmate  the 
outer  apical  angle  prolonged,  inner  side  deeply  emarginate  with  the  inner  spur 
above  the  emargination.     Tarsi  slender. 

From  the  above  characters  it  is  evident  that  the  tribe  must  be  sub- 
divided into  two  groups  in  the  following  manner : 

Basal  joint  of  antennae  long.     Mentum  broad,  concealing  at  the  sides  the  base  of 
the  maxillae.     Head  with  one  supra-orbital  setigerous  puncture,  thorax  with 

one  setigerous  puncture  at  the  hind  angle Scarites. 

Basal  joint  of  antennae   not   elongated..    Base  of  maxillae   not   covered   by  the 
mentum.     Head  with  two  supra-orbital  setigerous  punctures,  sides  of  thorax 

with  two Clivin^. 

In  addition  to  the  above  characters  the  form  of  the  labial  palpi  and 
the  paraglossEe  give  additional  means  of  separating  the  groups. 

The  sexual  characters  of  the  genera  of  this  tribe  are  very  feeble. 
In  Scarites  the  last  ventral  segment  has  four  marginal  punctures, 
in  the  female  the  inner  two  are  more  distant  from  each  other  than 
from  the  outer,  while  in  the  male  they  are  equidistant.  In  Pasi- 
machus some  species  have  the  posterior  tibiae  pubescent  within  at  tip 
in  the  male.  There  are  no  marginal  punctures  on  the  last  ventral 
segment,  in  the  males  there  will  usually  be  observed  on  each  side  one 
ante-apical  puncture  and  in  the  females  two,  but  these  are  not  constant 
in  any  respect. 

In  the  Clivinae  the  last  segment  is  the  same  as  in  Scarites,  the 
tarsi  are  often  alike  slender  in  both  sexes  but  when  dilated  are 
more  so  in  the  male.  In  DyscMrius  the  palpi  differ  as  will  be  seen 
below. 

The  antennse  vary  in  the  number  of  glabrous  basal  joints,  the  Scarites 
have  four  and  the  Clivinae  two.  In  Aspidoglossa  the  base  of  third  is 
glabrous  but  even  here  as  in  all  the  Clivinse  the  second  joint  though  not 
pubescent  is  hairy. 


AMERICAN    COLEOPTERA.  121 

Group   SCARITES. 

In  our  fauna  two  genera  occur  separated  in  the  following  manner : 

Hind  angles  of  thorax  distinct.     Elytra  with  humeral  carina  of  variable  length. 

Maxillse  very  obtuse  at  tip Pasimachus. 

Hind  angles  of  thorax  wanting.    Elytra  without  humeral  carina.    Maxilla?  slightly 

hooked  at  tip Scarites. 

In  these  two  genera  the  four  basal  joints  are  glabrous  and  in  repose 
the  scape  is  received  in  a  depression  beneath  the  eye. 

Group  CLiviNiE. 

The  genera  which  occur  with  us  are  as  follows : 

Margin  of  elytra  entire.     Mandibles  flat  and  arcuate. 
Anterior  tarsi  slender  in  both  sexes. 

Palpi  dissimilar  in  the  sexes,  the  terminal  joint  more  dilated  in  the  male,

Anterior  tarsi  more  or  less  dilated  in  both  sexes.

Mentum  deeply  emarginate.     Head  with  numerous  longitudinal  grooves.

Margin  of  elytra  interrupted  posteriorly  and  with  an  internal  j)lica.     Mandibles

In  the  arrangement  of  the  genera  of  this  group  I  regret  that  I  am 
unable  to  follow  my  friend  M.  Jules  Putzeys,  nor  can  I  from  my 
dissections  find  the  ligular  characters  which  he  aims  to  illustrate  in 
his  Postscriptum  (Mem.  Liege  xviii,  1863).  The  dissection  of  the 
species  of  this  group  is  by  no  means  an  easy  task,  and  the  difficulties 
attendant  on  its  accomplishment  must  be  the  cause  of  the  entire 
absence  of  resemblance  between  the  drawings  of  M.  Putzeys  and  the 
objects  themselves. 

In  all  our  genera  the  ligula  is  small  and  is  usually  hidden  by 
the  supports  of  the  labial  palpi.  The  ligula  is  slender,  the  tip  more 
or  less  acute,  free  and  biseti'gcrous  the  paraglossse  slender  and  acute, 
not  longer  than  it.  The  form  of  the  maxillae,  mentum,  ligula  and 
palpi,  are  shown  in  the  accompanying  figures  and  need  no  further 
description.  Clivina  and  Dyscliirius  are  best  separated  by  the  form 
of  the  palpi,  all  other  characters  heretofore  given  fail  in  our  series 
of  species. 

As  arranged  in  the  preceding  table  our  genera  show  the  transition 
from  the  simple  form  of  inner  maxillary  lobe  of  PasimacJms  to  that 
which  is  the  more  common  form  in  all  Carabidse.

It  is  curious  in  this  tribe  that  Ardistomis  should  "have  the  elytral 
margin  interrupted  with  an  internal  plica.  It  thus  shows  considerable 
more  affinity  with  the  HarpalinEe  than  do  the  other  genera  and  seems 
to  be  the  nearest  Carabine  relation  of  the  Panagaeini,  in  place  of  the 
Cychrini  as  suggested  by  most  authors. 

Sub-Family  UARPALINjE. 

Middle  coxal  cavities  entirely  enclosed  by  the  central  pieces  of  the 
meso-  and  metasternum,  the  epimera  not  attaining  the  coxae.  Head 
with  setigerous  punctures  over  the  eyes.  Thorax  with  setigerous  punc- 
tures at  the  side  and  posterior  angle  very  rarely  without  the  latter 
and  still  more  rarely  without  either.  Anterior  tibiae  always  either 
obliquely  sinuate  or  deeply  emarginate  within,  the  inner  spur  remote 
from  the  apex. 

These  characters  seem  to  be  the  only  ones  in  which  all  the  tribes 
agree.  As  there  are  many  points  in  which  wide  differences  occur  these 
will  be  left  for  discussion  in  their  proper  places. 

For  convenience  of  study  the   sub-family  may  be   divided   in  two 
grand  sections. 
Head  with  two  supra-orbital  setigerous  punctures. 

Harpalinje  bisetos^. 
Head  with  one  supra-orbital  setigerous  puncture. 

Harpalin^  unisetos^. 

Small  as  this  character  may  seem  it  is  probably  one  of  the  most 
invariable  of  any  that  have  been  suggested  for  the  division  of  any  large 
series  of  genera  or  tribes.  I  have  never  observed  an  exception,  although 
Bedel  *  says  that  in  two  European  Amara  one  has  but  one  supra-orbital 
seta  (^spectabilis)  and  the  second  (^pyrenxa)  none  whatever. 

When  two  setae  occur  the  anterior  is  close  to  the  margin  of  the 
eye  in  front,  the  posterior  is  a  little  remote  from  the  eye  opposite  the 
posterior  margin.  When  there  is  one  seta  it  is  almost  always  a  little 
removed  from  the  margin  of  the  eye  and  is  situated  opposite  the  middle 
of  the  eye  or  a  little  posterior  to  that  point. 

The  Harpalinae  as  here  constituted  seem  to  be  the  true  development 
of  what  might  be  called  the  Carabide  idea  of  the  present  geological 
period.  There  is  evidently  a  close  relationship  in  the  entire  series  with 
fewer  breaks  in  the  line  of  affinity  and  with  very  few  genera  that  are 
abnormal  or*  specially  differentiated  in  the  sense  in  which  we  observe

AMERICAN    COLEOPTERA.  123 

it  in  the  Carabiriae.  It  will  be  observed  in  glancing  over  the  series  of 
tribal  and  genera  that  there  are  three  well  marked  types,  Fterostichus, 
Lehia  and  Harpalus,  closely  related  among  themselves  around  which 
we  may  group  other  types  either  more  or  less  intermediate  between  the 
three  or  related  to  them  as  a  centre  and  from  thence  diverging  with 
no  definite  affinity.  It  is  therefore  impossible  to  construct  any  linear 
arrangement  which  will  exhibit  all  the  evident  relationship  without  at 
the  same  time  interrupting  other  equally  evident  afiinities. 

The  tribes  which  follow  are  so  placed  that  those  which  seem  to  exhibit 
the  closest  relationship  with  the  Carabinae  are  at  the  beginning  with  those 
following  which  seem  to  lead  to  the  true  Harpaline  type. 

Those  with  the  two  supra-orbital  setae  will  be  considered  first  and  for 
convenience  of  reference  will  be  called  by  the  following  name. 

Harpaline  bisetos^. 

This  section  contains  by  far  the  larger  number  of  tribes  and  genera 
and  presents  many  difficulties  in  its  study.  Many  of  the  characters  used 
in  the  table  are  the  common  property  of  science  others  are  new  or  have 
been  brought  into  greater  prominence  for  the  first  time  here.  To  those 
acquainted  with  the  literature  of  the  subject  no  special  references  are 
needed. 

As  in  the  Carabinae  it  appears  to  have  escaped  notice  that  a  number 
of  genera  have  the  posterior  coxae  separated  and  the  metasternum  and 
abdomen  meeting.  This  is  an  important  character  and  its  use  is  attended 
with  good  results. 

The  internal  elytral  plica  by  its  presence  serves  to  separate  a  number 
of  tribes.  The  object  of  this  structure  is  to  afford  a  means  of  >support 
to  the  edge  of  the  abdomen  and  at  the  origin  of  the  plica  posteriorly 
the  last  ventral  segment  is  firmly  held  when  in  repose.  It  will  be 
observed  that  in  those  genera  with  a  plica  the  upper  edges  of  the 
ventral  segments  are  vertical,  those  without  the  plica  have  the  edge 
inflexed.  As  a  rule  the  pliciferous  genera  are  terrestrial  and  are  at  best 
feeble  flyers,  the  majority  of  the  others  are  easy  flyers  and  less  terrestrial 
in  their  habits.  This  however  is  merely  a  general  statement  with  many 
exceptions  on  both  sides. 

The  tribe  P  a  n  a  g  ae  i  n  i  is  placed  at  the  head  in  the  belief  that  some 
of  its  members  will  show  a  closer  relationship  with  the  Clivinse  than  has 
yet  been  indicated. 

The  table  which  follows  is  the  result  of  a  study  not  only  of  the 
genera  of  our  fauna  but  of  all  which  were  accessible,  the  cabinets  of 
the  Academy  of  Natural   Sciences,  supplemented  by  that  of  our  own

Society  have  afforded  an  amount  of  material  wliich  had  never  been 
properly  estimated.  Many  of  the  genera  will  be  found  mentioned  "in 
the  following  pages,  but  only  those  which  seemed  to  require  it  and 
which  are  but  a  part  of  those  actually  studied. 

Those  who  know  the  extent  of  the  subject  will  properly  esti- 
mate the  amount  of  labor  expended  and  with  the  hope  that  the 
table  will  prove  an  incentive  to  additional  work  with  many  improve- 
ments and  emendations,  it  is  presented  for  the  consideration  of  those 
interested.

12G  GEO.    II.    HORN,    M.  D. 

Tribe  XVI.— Panagseini. 
Antennae  slender  arising  under  a  distinct  frontal  ridge,  three  basal  joints 
glabrous,  without  fine  punctuation  and  pubescence,  but  ciliate.  Head  usually 
constricted  behind  the  eyes  and  dilated  to  a  semiglobular  neck,  front  with  two 
supra-orbital  setse.  Eyes  round,  rather  prominent,  distant  beneath  from  the  buccal 
opening.  Labrum  with  four  setse  only.  Maxillse  small  the  inner  lobe  slender, 
hooked  at  tip  ciliate  or  spinous  within,  outer  lobe  stout,  biarticulate,  palpi  elongate 
the  last  joint  triangularly  dilated  and  inserted  obliquely  on  the  preceding,  these 
two  hairy.  Mentum  emarginate,  toothed  at  bottom,  the  basal  suture  distinct. 
Ligula  moderately  prominent,  bisetose  at  tip  the  paraglossse  adherent  and  rarely 
longer  than  it,  palpi  moderate  in  length  the  terminal  joint  triangular.  Thorax 
variable  in  form.  Body  not  pedunculate,  scutellum  distinct.  Elytra  not  margined 
at  base,  sides  narrowly  inflexed,  margin  interrupted  posteriorly  and  with  an 
internal  plica.  Prosternum  not  prolonged.  Mesosternum'  oblique,  the  epimera 
very  narrow.  Metasternal  epimera  distinct,  posterior  coxse  contiguous.  Tibite 
ciliate  externally,  the  anterior  emarginate  within,  the  spurs  distant.  Tarsi  slender 
in  our  genera,  the  fourth  joint  bilobed  in  certain  exotic  genera. 

The  males  rarely  have  the  anterior  tarsi  dilated.  In  our  genera  the  first  two 
joints  of  the  anterior  tarsi  are  dilated  and  hairy  beneath. 

Of  late  years  authors  seem  pretty  well  in  accord  as  to  the  limits  of 
this  tribe.  Lacordaire  included  Loricera  which  has  already  been  dis- 
cussed. To  the  tribe  as  left  by  the  latter  author  Schaum  ( Ins.  Deutschl. 
i,  p.  318),  added  Tcjflus,  and  Disphrxricus  which  however  is  not  included 
by  Chaudoir  in  his  essay  on  the  tribe  (Ann.  Belg.  1878).  I  have  not 
seen  the  latter  genus  in  nature.  Geohius  included  by  Lacordaire  is 
excluded  by  Chaudoir  for  reasons  which  seem  scarcely  more  than  of 
generic  value.     I  cannot  see  any  relation  with  Pelecium. 

Chaudoir  in  the  characters  of  the  tribe  has  the  following  paragraph : 

"  Machoires  crochues  et  tres  ciliees  en  dedans,  lobe  inferieur  a  dernier 
article  court,  tr^s  large,  comprime  et  termine  par  un  petit  crochet 
( excepte 'dans  le  genre  Micrixyi).'" 

I  can  find  no  such  character  as  that  mentioned  for  the  outer  maxillary 
lobe  and  if  it  did  exist  would  be  uniqiie  in  the  tribe  and  extraordinary 
in  the  entire  family. 

The  affinities  of  the  tribe  are  not  well  marked  in  any  direction,  it 
appears  in  fact  to  stand  more  nearly  alone  than  any  tribe  of  the  present 
sub-family,  and  I  have  already  expressed  the  opinion  that  its  affinities 
with  the  Carabinae  are  rather  through  the  Clivina?  than  the  Cychrini. 
I  can  see  no  reason  for  suspecting  any  relationship  with  the  Chlaeniini. 

Two  genera  occur  in  our  fauna  which,  difi^r  in  the  following  manner : 
Clypeus   prolonged   beyond    the   base  of  the  mandibles,  the  latter  decussating, 

scissor-like Pauagseiis. 

Clypeus  emarginate  at  middle,  the  mandibles  stout,  pincer-like Micrixys. 

The  latter  genus  has  the  head  not  distinctly  constricted  but  the  neck 
is  of  the  same  semi-srlobular  form  as  in  the  former. 


AMERICAN    COLEOPTERA.  127 

In  both  genera  the  ocellate  punctures  which  are  usually  observed 
near  the  margin  of  the  elytra  in  Carabidfe  are  absent,  but  are  present 
in  other  genera  of  the  tribe.  I  have  observed  also  that  they  are  absent 
in  Apotomus,  a  genus  not  related  to  the  present  tribe. 

Tribe  XVII.— Siagonini. 

Antenn*  slender,  arising;  under  a  distinct  frontal  plate,  first  joint  elongate 
conical  pilose,  second  short  glabrous  at  base,  3 — U  equal  and,  with  the  apex  of 
the  second,  pubescent.  Clypeus  prolonged  at  middle.  Head  depressed,  quadrate, 
two  approximated  supra-orbital  setse.  Eyes  small  oval,  truncate  posteriorly,  very 
distant  beneath  from  the  buccal  fissure.  Labruni  sinuate  or  denticulate.  Mandi- 
bles strongly  arcuate,  either  dentate  or  simple  within,  scarcely  concave  externally 
without  setigerous  puncture.  Maxillae  ciliate  within,  the  outer  lobe  with  terminal 
joint  longer,  palpi  stout,  the  joints  with  short  hairs,  the  terminal  shorter  than  the 
preceding,  oval,  truncate  at  ti[).  Mentum  large  almost  entirely  concealing  the 
maxillfe,  the  suture  at  base  indistinct,  deeply  emarginate  and  with  a  large  bifid 
tooth,  ligula  large  prominent,  slightly  emarginate  in  front  and  plurisetose,  the 
paraglossse  corneous  and  closely  united  with  it,  palpi  moderate,  last  joint  securi- 
form. Thorax  narrowed  at  base,  grooved  above  and  with  a  setigerous  puncture 
on  the  hind  angle  and  others  along  the  side  margin.  Body  pedunculate.  Elytra 
elongate-oval,  depressed,  sides  narrowly  inflexed,  margin  entire,  base  not  margined. 
Prosternum  not  prolonged.  Mesosternum  rather  widely  separating  the  coxsp, 
horizontal,  the  epimera  narrow  and  not  attaining  the  coxal  cavity.  Metasternal 
epimera  small  but  distinct.  Posterior  coxae  slightly  separated,  the  first  ventral 
segment  distinct  between  them.  Anterior  tibiae  emarginate  within  and  deejily 
obliquely  grooved,  the  inner  spur  superior.     Tarsi  simple  in  the  two  sexes. 

This  group  contains  but  one  genus  Slngona  (possibly  also  Luperca  = 
Holosceh's),  not  represented  in  our  fauna.  It  has  been  made  by  most 
authors  the  type  of  a  tribe  and  placed  in  the  Carabinfe.  The  Siagonides 
of  European  authors  contains  two  very  dissimilar  elements.  Enre/adns 
and  Lnperca  (?)  having  the  middle  coxfe  partially  closed  extei'nally  by  the 
mesosternal  epimera  form  in  the  present  essay  the  tribe  Enceladini  of 
the  sub-family  Carabinje.  Siogonn  on  the  other  hand  has  the  meso- 
sternal structure  of  the  present  sub-family  and  Schioedte,  Schaum  and 
Chaudoir  have  been  deceived  by  a  mere  plication  in  the  mesosternal  side 
pieces  and  have  been  lead  to  believe  that  the  mesosternal  epimera  reach 
the  coxae.  By  macerating  a  specimen  of  Stngnna  for  a  sufficient  time 
in  a  solution  of  caustic  potassa  the  sutures  become  apparent  and  will  be 
found  as  stated  above. 

The  latest  review  of  the  Siagonini  is  that  published  by  Baron  Chaudoir 
(Bull.  Mosc.  1876),  in  which  Evrefadus  still  retains  its  place  in  the 
tribe.  In  recognizing  the  great  value  of  the  discovery  (which  we  owe 
to  Dr.  LeConte),  of  the  diiference  in  form  of  the  mesosternal  epimera  in 
the  sub-families  of  Carabidae,  Chaudoir  states  that  in  associating  Slngona 
with  Encehidiii^  one  reasons  rather  by  arialogy  as  the  suture  which  sepa- 


128  GEO.    H.    HORN,    M.  D. 

rates  the  epimera  is  so  obsolete  as  not  to  be  distinguished.  It  is  to  be 
regretted  that  so  able  an  entomologist  should  have  allowed  himself  to 
perpetuate  an  error  when  the  truth  was  so  nearly  within  his  grasp  and 
so  easily  obtained,  and  had  the  above  mentioned  process  (so  well  known 
to  microscopists)  been  made  use  of,  more  service  would  have  been  done 
to  science  than  by  many  ligular  dissections. 

If  I  have  correctly  interpreted  the  feeble  traces  of  the  suture  at  the 
base  of  the  mentum  this  organ  is  not  attached  merely  to  the  central 
gular  piece  but  also  to  the  side  pieces  of  the  gula,  in  a  manner  similar  to 
that  observed  in  the  Pseudomorphinae.  In  all  other  Carabidae  which 
I  have  dissected  the  central  gular  piece  is  expanded  at  tip  and  forms 
the  entire  basal  attachment  of  the  mentum  even  in  those  genera  with 
a  very  broad  mentum. 

With  a  very  indefinite  relationship  with  the  Pseudomorphinae  the 
present  tribe  shows  very  decided  affinities  with  the  Ozaenini. 

Tribe  XVIIL— Ozeenini. 

Antennae  arising  under  distinct  frontal  plates,  the  four  basal  joints  not  finely 
pubescent  but  hairy.  Clypeus  prolonged  at  middle.  Head  more  or  less  narrowed 
behind  the  eyes  to  a  neck  and  with  at  least  two  supra-orbital  setae.  Eyes  round, 
moderately  prominent,  irregular  in  outline  behind',  distant  from  the  buccal  open- 
ing beneath  by  the  moderately  widened  genoe.  Mentum  broad,  the  suture  at  base 
usually  very  plainly  visible,  toothed  (except  Eusira),  ligula  moderate  or  small, 
the  paraglossse  narrow  and  entirely  adherent,  the  palpi  variable  in  form,  the 
terminal  joint  usually  cylindrical,  flattened  and  truncate  at  tip,  the  maxillary 
palpi  similar.  Thorax  with  numerous  small  setigerous  punctures  along  the  margin. 
Body  more  or  less  pedunculate.  Scutellum  not  prolonged  between  the  elytra. 
Elytra  not  margined  at  base,  narrowly  inflexed  at  the  sides,  margin  interrupted 
one-third  from  apex  but  without  internal  plica.  Presternum  not  prolonged  at  tip. 
Mesosternum  very  narrow,  in  some  cases  not  separating  the  middle  coxas.  Meso- 
sternal  epimera  broad,  not  attaining  the  middle  coxae.  Metasternal  epimera  visible. 
Posterior  coxae  distant,  the  first  ventral  segment  visible  between  them.  Anterior 
tibiae  emarginate  on  the  inner  side  the  spurs  distant.  Tarsi  slender,  simple  in 
the  two  sexes. 

The  sexual  characters  are  feeble,  the  males  sometimes  having  the  anterior 
femora  toothed  beneath. 

By  all  European  authors  this  tribe  has  been  placed  in  the  series  in 
which  the  mesosternal  epimera  attain  the  coxal  cavities.  The  idea 
originated  with  Schioedte,  has  been  adopted  by  Schaum  and  acknowl- 
edged by  Chaudoir. 

The  latter  gentleman  with  his  usual  sagacity  realizes  the  impropriety  of 
such  a  position  of  the  tribe  and  uses  the  following  language  (Ozenides,  Ann. 
Belg.  xi,  1868,  p.  3),.in  reference  to  the  epimera!  character  :  "un  caractere 
auquel  Schioedte  et  apres  lui  beaucoup  d'entomologistes  ont  pendant  quel- 
que  temps  attache  uiu'  iniportaliee  ({uc  je  trouve  maintenant  exageree." 


AMERICAN    COLEOPTERA.  129 

After  a  careful  examination  of  Phi/sea  and  Pachyteles  I  find  that  tlie 
mesosternal  epimera  do  not  attain  the  middle  coxjb,  and  that  no  better 
evidence  is  required  of  the  value  of  the  character  .than  the  fact  that 
these  genera  and  their  allies  are  thereby  excluded  from  the  Carabinae. 

The  value  of  the  character  drawn  from  the  mesosternum  is  certainly 
very  much  overestimated,  as  it  will  be  observed  that  while  certain  species 
of  Pachyteles  {marginicolUs,  biguttatus),  have  the  middle  coxae  as  dis- 
tinctly separated  as  in  many  Platynus,  others  have  the  middle  coxal 
cavities  confluent  {mexicaiiua).  It  will  be  observed  however  that  there 
is  an  unusual  degree  of  flexibility  of  the  central  region  of  the  body  and 
that  the  articulation  between  the  meso-  and  metathorax  is  rather  loose. 
The  lateral  process  of  the  central  piece  of  the  mesosternum,  that  is,  those 
processes  which  partly  enclose  the  coxae  externally,  are  capable  of  a  slight 
motion  under  the  opposite  processes  of  the  metasternum  and  the  limit  of 
this  motion  is  indicated  by  a  slight  ridge  on  the  former  process,  which 
ridge  is  exactly  continuous  with  the  suture  separating  the  mes-episternum 
from  the  mes-epimeron  and  has  been  the  unfortunate  cause  of  the  de- 
ception of  all  those  who  have  heretofore  studied  these  parts.  For  those 
who  desire  to  verify  the  above  statements  a  preparation  made  in  the 
manner  indicated  for  Siagoiia  will  remove  all  doubts. 

The  interruption  of  the  lateral  margin  of  the  elytra  is  a  character 
entirely  different  from  that  observed  in  the  succeeding  tribes.  If  the 
margin  is  followed  from  the  apex  to  the  interruption  it  will  be  observed 
that  this  end  passes  over  that  which  is  formed  by  the  anterior  portion, 
while  in  the  Pterostichini,  etc.,  the  posterior  end  passes  under  the  anterior 
and  is  continued  oh  the  under  side  of  the  elytron  in  a  long  ridge. 

The  relationships  of  the  Ozasnini  are  feeble  in  the  direction  of 
Pseudomorpha  and  Siogonn^  but  more  decided  toward  Nomius  and 
Pxj/drus  which  lead  through  the  Morionini  to  the  ccnti'al  mass  of  the 
Harpaline  series. 

Alijstropomu^  placed  here  liy  Chaudoir  seen)s  to  me  to  lie  a  true 
Carabine  allied  to  Metrius. 

One  genus  is  represented  in  oiir  fauna,  and  the  .species  Pachi/teles 
tesfaceus  Horn,  occurs  in  Arizona.  Physea  has  occurred  at  Tampico, 
Mexico,  and  may  possibly  be  found  in  Texas. 

Tribe  XIX.— Nomiini. 

Antennae  somewhat  nioniliform,  arising  nndei-  a  distinct  frontal  ridge,  four 
basal  joints  glabrous,  first  joint  stouter  not  long,  third  nearly  as  long  as  the  two 
following,  terminal  oval  acuminate.  Head  stout,  oval,  neck  broad,  front  with  two 
svipra-orbital  setse,  clypeus  slightly  prolonged.  Eyes  round,  prominent,  free  pos- 
teriorly, closely  approaching  the  buccal  opening  beneath.     Lal)rum  short,  broadly

emarccinato.  Mandibles  slislitly  prominent,  arcuate,  acute  at  tip.  inner  edge  feebly 
tiiurlii'd  .-it  iniildle,  outer  Iowit  edge  slightly  expanded,  the  outer  (ace  concave  and 
uiili  a  di-iinct  seiigeriiiis  puncture.  Maxillie  ^Jtout,  with  a  double  row  of  short 
stilt'  spines  within,  ])alpi  stout,  teriuiual  joint  slightly  fusiform  and  obtuse  at  tip. 
Mentuui  broad,  deeply  emarginate  without  tooth,  basal  suture  distinct.  Ligula 
short,  broad,  aciute  and  bisetose  at  tip,  the  paraglossse  slender  slightly  longer  than 
it  and  ciliate  within  at  tip,  palpi  short,  last  joint  slightly  fusiform,  obtuse  at  tip. 
Thorax  with  two  setae  near  the  front  angles  and  one  at  the  posterior.  Body 
pedunculate,  scutellum  not  visible  between  the  elytra.  Elytra  slightly  margined 
at  base  near  the  hind  angles,  sides  very  narrowly  inflexed,  margin  slightly 
interrupted  posteriorly  and  with  a  short  internal  plica,  no  dorsal  punctures. 
Prosternum  obtuse,  not  prolonged  at  tip.  Mesosternum  oblique  the  coxse  sepa- 
rated, epiinera  and  episterna  nearly  equal.  Posterior  coxae  contiguous.  Abdomen 
with  posterior  margins  of  segments  3 — 4—5  narrowly  coriaceous.  Legs  moderate, 
middle  and  posterior  tibife  ciliate  externally,  the  anterior  slightly  broader  at 
tip,  emarginate  within,  tlie  spurs  distant.  Tarsi  not  dilated.  Sexual  characters 
as  in  Scarites. 

As  far  as  I  can  ascertain  this  tribe  is  represented  by  a  single  genus 
Nomiua^  (Haplochile  Lee),  the  position  of  which  has  been  the  cause 
of  differences  of  opinion.  For  Dejean,  Duval  and  Schaum  it  was  a 
Morionide,  Lacordaire  (not  knowing  Haplochile),  places  Nomius  in  the 
Ozenides  and  Haplochile  in  Morionides.  Chaudoir  properly  omits  it 
from  his  essay  on  the  Ozenides,  while  Bedel  (Ann.  Fr.  1879,  suppl. 
pp.  24  and  42),  places  it  in  his  tribe  Bembidiini  which  is  part  of  a  very 
heterogeneous  and  impossible  sub-family  Bembidiidas.  Under  Psi/drus 
will  be  found  its  history  in  our  fauna. 

From  the  Morionini  it  differs  in  the  form  of  the  anterior  tibite  and 
mesosternal  epimera  and  the  presence  of  a  mandibular  setigerous  punc- 
ture, the  form  of  the  ligula  and  paraglossoe  and  the  structure  of  the 
abdomen. 

The  mesosternum  is  not  narrow  between  the  coxa3  but  emarginate, 
receiving  the  metasternum  and  in  this-  respect  differs  greatly  from  the 
Ozaenini  which  have  the  mesosternum,  at  most,  linear  between  the  coxae 
and  never  wide  enough  at  tip  to  be  emarginate. 

I  cannot  understand  why  Bedel  is  willing  to  place  Nomius  near 
Bembidium,  Patrobus,  etc.,  the  only  point  in  which  it  resembles  these 
is  in  the  presence  of  mandibular  seta.  Its  affinities  seem  to  me  to  be 
best  indicated  by  placing  it  between  the  Ozaenini  and  the  Morionini. 

Nomius  contains  but  one  species  N  pi/fjmseus  Dej.,  which  occurs  in 
various  parts  of  southern  Europe,  and  in  many  places  in  our  country 
from  Georgia  to  California. 

It  occurs  under  stones,  etc.,  in  moist  places,  and  exhales  a  strong- 
fetid  odor. 

To  this  tribe  two  anomalous  foreign  genera  should  be  referred  Mc/prniis

and  Coacinia.  Thp8e  with  Nomiuif  seem  to  represent  three  tirnups  in 
the  tribe.  Coscinia  lias  very  little  relationship  with  Sluf/oim  execjit  a 
slight  resemblance  in  a.spcct.  All  the  genera  of  this  tribe  as  thus  detined 
have  a.  well  marked  elytral  plica  internally,  a  character  sufficiently  re- 
stricted in  its  distribution  to  indicate  more  or  less  ajipmximately  tlie 
relationship  of  genera  possessing  it. 

For  the  privilege  of  examining  these  genera  I  am  indebted  to 
Mr.  H.  W.  Bates. 

Tribe  XX.— Psydrini. 
Antennse  moderate  arising  under  a  distinct  frontal  ridge,  first  joint  moderately 
stout,  cylindrical,  third  longer  than  second,  the  three  basal  joints  and  the  base  of 
fourth  glabrous,  4 — 10  elongate-ovate,  eleventh  nearly  as  long  as  the  two  preceding. 
Head  triangular,  moderately  constricted  behind  the  eyes  forming  a  broad  neck, 
front  with  two  supra-orbital  setigeruus  jnuictures  the  jtosterior  distiiiil  Iimjui  ibe 
margin  of  the  eye,  epistome  slightly  prolonged.  Eyes  oval,  slightly  liinicaie 
behind,  distant  beneath  from  the  buccal  opening.  Liibrum  short,  slightly  cmiii- 
ginate.  Mandibles  moderately  prominent,  arcuate,  acute  at  tip,  inner  margin  witli 
a  small  tooth  at  middle,  outer  edge  concave  and  without  setigerous  puncture. 
Maxillse  spinous  within,  the  palpi  moderate,  the  last  joint  longer  than  the  pre- 
ceding. Mentum  broad,  lateral  lobes  rounded,  deei)ly  emarginate  and  with  a  short, 
broad,  bifid  tooth,  the  mental  suture  distinct.  Ligula  short  and  broad,  truncate 
and  sexsetose  at  tip,  the  paraglossee  semicorneous  adherent  in  all  their  length  and 
not  longer  than  the  ligula,  the  palpi  rather  short,  last  two  joints  equal,  the  termi- 
nal somewhat  fusiform  and  truncate  at  tip.  Thorax  trapezoidal,  sides  with  three 
setigerous  punctures,  one  at  each  angle  and  one  slightly  in  front  of  middle.  Body 
not  pedunculate,  scutellum  distinct  between  the  elytra.  Elytra  slightly  margined 
at  base  near  the  humeri,  sides  narrowly  inflexed,  lateral  margin  slightly  inter- 
rupted posteriorly  and  with  a  short  internal  plica,  disc  punctato-striate,  two  dorsal 
punctures  on  the  third  interval  adjacent  to  the  third  stria,  one-fourth  from  base 
and  one-fourth  from  apex.  Prosternum  not>  prolonged.  Mesosternum  nearly  fiat, 
the  middle  coxse  distant,  epimera  wide  nearly  equalling  the  episterna.  Meta- 
sternal  epimera  distinct,  posterior  coxse  contiguous.  Ventral  segments  3 — 4—5 
with  posterior  margins  coriaceous.  Legs  moderate,  the  tibise  snjooth  externally, 
the  anterior  emarginate  within,  the  spurs  distTant. 

The  anterior  tarsi  do  not  difier  in  the  sexes,  the  sexual  characters  are  the  same 
as  in  Scarites. 

The  only  genus  known  to  me  which  can  be  referred  to  this  tribe  is 
Psyclrus.     Its  form  is  not  unlike  some  Bembidia,  the  color  piceous. 

Regretting  the  multiplication  of  tribes,  I  can  find  no  place  in  which 
the  genus  can  be  put  and  atn  compelled  to  adopt  the  present  course  and 
consider  it  the  type  of  a  tribe  the  affinities  of  which  are  in  the  direction  of 
NoTniux  and  Siagonu,  as  well  as  in  a  less  marked  degree  toward  Mario. 

Psydrus  was  originally  placed  near  Ozsena,  (Ann.  Lye.  iv,  p.  153), 
subsequently  with  Haplochile  (==  Nomius),  as  a  group  of  the  tribe 
Broscini,  a  position  retained  in  the  Class.  Col.  N.  Am.  p.  30,  Lacordaire 
in  the  meantime  placing  it  in  the  Morionini.     None  of  these  positions 


132  GEO.    H.    HORN,    M.  D. 

seem  to  me  tenable,  Ozjenini  having  the  posterior  coxaj  separated,  Nbmius 
tlie  body  pedunculate  and  a  mandibular  seta,  Morio  the  anterior  tibiae 
dilated  and  body  ♦pedunculate.  If  we  take  the  ligula  as  a  point  of 
comparison  the  resemblance  is  rather  with  Pachyteles  (which  however, 
has  but  two  seta3  or  Siagona  wheje  there  are  six)  than  with  Morio  and 
Nomius  where  the  paraglossae  are  long  and  slender. 

The  body  is  not  at  all  pedunculate  and*  there  are  two  supra-orbital 
setae,  characters  which  perfectly  exclude  it  from  all  association  with 
Broscini.  There  can '  be  no  suspicion  of  association  with  Pterostichini 
from  the  differences  in  tarsal  and  antennal  structure. 

There  is  then  no  course  left  but  to  consider  it  a  distinct  tribe  leading 
directly  from  the  Siagonini,  Ozsenini  and  Nomiini  through  Morio  to 
the  Pterostichini. 

One  species  of  Fsydrus  is  known  ( P.  piceus  Lee),  which  occurs  from 
Lake  Superior  to  northern  California.  I  fou«d  it  in  the  latter  region 
living  under  dead  bark,  it  ejects  a  liquid  from  its  anus  when  disturbed 
which  is  not,  like  in  Nomius^  especially  offensive. 

Tribe  XXL- Morionini. 

Antennae  more  or  less  moniliform  with  four  entirely  glabrous  joints,  arising 
under  slight  frontal  plates.  Head  suddenly  narrowed  behind  the  eyes,  neck  stout, 
front  with  two  supra-orbital  setae,  clypeus  slightly  prolonged.  Eyes  round,  moder- 
ately prominent,  truncate  posteriorly  by  the  sides  of  the  head,  distant  beneath 
from  the  buccal  opening.  Mandibles  at  least  slightly  prominent  without  setigerous 
puncture  externally.  'Maxillae  ciliate  internally  (with  a  tooth  behind  the  apex  in 
Morio) ;  the  palpi  moderate,  the  last  joint  slightly  fusiform.  Mentum  deeply 
emarginate,  usually  with  a  bitid  tooth ;  ligula  broad,  free  and  bisetose  at  apex, 
the  paraglossre  slender,  longer  than  it,  not  ciliate;  palpi  moderate  the  last  joint 
cylindrical  (longer  than  that  of  the  maxillary  Morio).  Thorax  with  a  setigerous 
puncture  at  each  angle  (and  three  at  the  side  Morio).  Body  slightly  pedunculate, 
scutellum  distinct.  Elytra  feebly  margined  at  base,  sides  narrowly  inflexed,  disc 
with  a  single  dorsal  puncture  at  apical  third,  on  the  third  interval  near  the  third 
stria,  margin  with  a  very  feeble  interruption  but  with  a  distinct  internal  plica. 
Prosternum  not  prolonged.  Mesosternum  rounded  in  front,  the  epimera  veiy 
narrow.  Metasternal  side  piec^es  nai-row,  the  epimera  distinct,  posterior  coxte  con- 
tiguous. Ventral  segments  witliput  coriaceous  margin.  Tibiae  gradually  broader 
to  apex,  the  middle  tinely  spinflose  externally,  the  anterior  more  dilated,  the 
apical  angle  somewhat  prolonged,  inner  side  deeply  emarginate.  the  inner  spur 
above  the  emargination. 

The  first  three  joints  of  the  anterior  tarsi  are  slightly  dilated  in  the  male. 
The  remarks  which  have  been  made  on  the  preceding  tribes  and  their 
relationship  with  the  present,  sufficiently  explain  the  views  intended  in 
the  present  paper.  As  constituted  by  Lacordaire  (Genera  i,  p.  180),  the 
tribe  is  a  mixture  of  very  dissimilar  material.  Psydrui^  and  Nomius  are 
already  excluded.      Schaum  (Berl.  Zeitschr.  18(30,  p.  177),  suggests  the 


AxMERICAN    COLEOPTERA.  133 

exclusion  of  Physocrotaphna  and  its  union  with  the  HeUuonini  in  which 
position  it  appears  in  the  Munich  Catalogue.  From  the  figures  and 
description  it  seems  to  me  probable  that  this  also  is  incorrect,  while  the 
details  already  known  to  me  seem  clearly  to  indicate  its  afiiuities,  but  not 
knowing  the  insect  in  nature  it  seems  unnecessary  to  venture  farther. 

Those  genera  without  neck  to  the  head  should,  in  great  part,, if  not 
all  be  excluded,  especially  those  with  truncate  elytra  (see  remarks  on 
Basoh'a,  etc.,  in  Cratocerini).  This  tribe  is  represented  in  our  fauna 
by  Morio  monilicornis  Latr.,  a  shining  black  insect  of  moderate  size, 
resembling  somewhat  Pterostichus.  It  occurs  in  the  Southern  States 
and  is  found  under  bark. 

Tribe  XXII.— Bembidiini. 

Antennfe  slender,  arising  under  a  slight  frontal  margin,  tlie  first  two  or  often 
the  first  only  glabrous,  third  joint  sometimes  not  longer  than  the  seeond.  Head 
rarely  narrowed  behind  the  eyes  to  a  neck  ( Thafafisobius) ,  with  two  supra-orbital 
setse.  Eyes  round  prominent,  very  narrowly  sejjarated  beneath  from  the  mouth 
{ahsent  in  Anillus  and  Scotodipnus).  Clypeus  usually  inoderateh' prolonged  and 
with  an  erect  seta  on  each  side.  Labrum  transverse,  sexsetose  in  front,  rarely 
quite  small  (certain  Bembidia).  Mandibles  feebly  arcuate,  acute  at  tip  and  with 
a  setigerous  puncture  externally.  Maxillw  slender,  hooked  lit  tip,  ciliate  or  slightly 
spinulose  within,  the  outer  lobe  slender  and  biarticulate  or  with  the  two  joints 
united  (Amerizus),  the  palpi  moderate  in  length,  the  last  joint  usually  snuill, 
subulate,  sometimes  conical,  the  penultimate  club-shaped  and  pubescent.  Mentuin 
with  basal  suture  distinct,  variably  emarginate,  toothed,  the  tooth  simple  or 
notched,  the  ligula  broader  in  front,  free  and  truncate  at  tip  and  bisetose,  the  setre 
usually  very  closely  approximated,  the  paraglossse  slender,  longer  than  the  ligula 
and  not  ciliate  within,  the  palpi  moderate  in  length,  the  terminal  joint  small, 
subulate,  the  penultimate  more  or  less  club-shaped  and  bisetose  in  front.  Thorax 
with  a  setige'rous  puncture  at  the  side  and  at  the  hind  angle.  Elytra  sometimes 
margined  at  base,  sides  narrowly  inflexed,  the  margin  interrupted  posteriorly  and 
with  a  distinct  internal  plica,  disc  with  dorsal  punctures  or  fovete.  Prosternum 
not  prolonged.  Mesosternum  moderately  separating  the  coxa;,  the  epimera  moder- 
ately broad  and  wider  externally.  Metasternal  epimera  distinct,  posterior  coxaj 
contiguous.  Legs  moderate,  the  middle  and  posterior  tibiae  slightly  ciliate  exter- 
nally, the  anterior  deeply  emarginate  within  and  sometimes  with  the  outer  apical 
angle  obliquely  truncate  '(certain  Tachyti).  Tarsi  slender,  claws  simple,  rarely 
serrulate  {Elaphropv.x).     Surface  usually  glabrous,  pubescent  in  ( Tachypus). 

The  males  have  usually  two  joints  of  the  anterior  tarsi  dilated  and  squaniu- 
lose  or  pilose  (Tachypus)  beneath,  but  in  some  Tachys  the  tarsi  are  simihir  in 
the  sexes. 

This  tribe  is  about  as  well  defined  as  any  in  the  Carabidse,  the  form 
of  the  hist  joint  of  the  palpi  being  peculiar  to  it  and  giving  the  name  by 
which  it  is  often, known,  Suhuliptdpi . 

It  is  remarkable  that,  in  a  tribe  so  remote  from  Caliistun,  the  form 
of  the  outer  lobe  of  the  maxilla  in  that  genus  should  be  here  repeated. 
It  must  however  be  especially  remarked,  that  there  is  in  Amerizva  no 

(29). 


134  GEO.    H.    HORN,    M.  D. 

such  complete  fusion  of  the  two  pieces  as  in  Callistus  where  the  suture 
is  not  at  all  visible.  In  the  former  genus  the  suture  is  plainly  evident 
if  the  under  side  is  examined  and  not  visible  on  the  upper  as  shown 
in  figure  38. 

The  serrate  claws  of  Elaphropus  Motsch.,  is  a  very  singular  cha- 
racter to  occur  in  the  present  tribe,  that  it  does  occur  I  have  assured 
myself  by  the  examination  of  a  specimen  which  I  owe  to  the  liberality 
of  Dr.  Dohrn.  The  species  of  this  genus  resemble  Tacliys  and  notably 
incurvus,  etc. 

The  genera  known  to  occur  in  our  fauna  are  as  follows : 

Anterior  tibiae  not  obliquely  truncate  at  apex.    Sutural  stria  not  recurved  at  apex. 
Eyes  large  or  moderate. 

Elytra  punctured  without  strise,  surface  finely  pubescent Tachypus. 

Elytra  striate  or  striato-punctate,  glabrous Bembidium. 

Eyes  entirely  wanting Ailillus. 

Anterior  tibise  obliquely  truncate  at  apex.     Sutural  stria  recurved  at  apex. 

Elytra  with  the  eighth  stria  interrupted  or  less  deep  at  middle Tachys. 

Elytra  with  the  eighth  stria  very  deep Pericompsiis. 

With  Bembidium  I  include  Li/mnaeum  and  also  for  the  present 
Amerizus  Chaud.  (Rev.  Mag.  Zooh  1868).  The  latter  genus  was 
founded  on  Trechus  spectahilis  Mann.,  from  the  peculiar  structure  of 
the  outer  maxillary  lobe.  Beneath  his  generic  description  Chaudoir  takes 
occasion  to  refer  Trechus  ohlongulus  Mann.,  to  the  genus  Lymnseum, 
as  an  aberrant  species.  On  dissection  I  find  the  outer  maxillaiy  lobe 
probably  more  completely  consolidated  than  in  the  true  Amerizus. 
Rather  than  recognize  a  genus  with  two  so  dissimilar  species  I  think 
it  better  to  ignore  the  character  and  refer  both  to  Bembidium  where 
each  will  find  better  associates.  It  is  well  known  that  the  mouth  parts 
in  Bembidium  vary  otherwise  to  an  extent  which  would  be  considered 
generic  in  other  parts  of  the  series  but  all  attempts  to  divide  it  have  thus 
far  been  unsuccessful,  the  characters  becoming  evanescent. 

Tachypus  is  however  capable  of  feeble  definition  but  the  general 
appearance  of  the  species  is  so  distinct  that  it  seems  preferable  to 
retain  it. 

Tacliys  and  Pericompsus  should  probably  be  united  the  characters 
separating  the  latter  being  rather  those  of  a  group  of  species  than 
a  genus. 

After  placing  at  the  head  of  the  present  series  those  tribes  which 
appear  to  link  the  aggregate  Carabinge  and  Harpalinse,  the  present  tribe 
should  then  follow  as  that  which  most  intimately  connects  a  particular 
tribe  (Elaphrini),  of  the  former  with  the  latter.  Next  in  order  follow 
naturally  the  Pogonini  and  Pterostichini. 


AMERICAN    COLEOPTERA.  135 

Tribe  XXIII.— Pogonini. 

AntennfE  slender  arising  under  a  feeble  frontal  ridge,  the  third  joint  usually 
very  little  longer  than  the  second,  the  first  two  joints  only  glabrous.  Head  some- 
times constricted  behind  the  eyes,  two  supra-orbital  setse.  Eyes  (sometimes  absent), 
rarely  prominent,  distant  beneath  from  the  mouth.  Clypeus  moderately  prolonged 
and  with  a  setigerous  puncture  each  side.  Labrum  short,  truncate  or  broadly 
emarginate,  plurisetose  in  front.  Mandibles  moderately  prominent,  feebly  arcuate, 
acute  at  tip  and  with  a  setigerous  puncture  on  the  outer  side.  Maxillse  slender, 
acute  at  tip,  ciliate  with  a  few  stiff  hairs  inside,  the  outer  lobe  biarticulate,  palpi 
moderate  or  long,  the  terminal  joint  variable  but  hot  subulate,  the  penultimate 
joint  not  pubescent.  Mentum  broad,  its  basal  suture  often  obsolete,  deeply  emar- 
ginate and  toothed,  the  tooth  bifid  or  simple,  the  epilobes  often  dentiform,  ligula 
moderately  prominent,  usually  broad  the  tip  free  and  arcuate,  uni-  or  bisetose 
{Pogoni)  or  even  plurisetose  (Trechi),  the  paraglossije  slender,  very  little  longer 
than  the  ligula  and  not  ciliate  within  [Pogoni)  or  slender,  long  and  ciliate  within 
at  tip  [Trechi),  the  palpi  slightly  variable  the  last  joint  not  subulate.  Thorax 
with  a  seta  at  the  sides  and  at  hind  angle.  Body  not  pedunculaie,  scutellum 
distinct.  Elytra  sometimes  margined  at  base,  sides  narrowly  inflexed,  margin 
posteriorly  entire  or  with  a  very  feeble  sinuation  and  without  internal  plica,  disc 
more  or  less  striate,  dorsal  punctures  distinct.  Prosternum  not  prolonged  at  tip. 
Mesosternum  declivous  in  front,  moderately  separating  the  coxse,  the  epimera 
narrow.  Metasternum  variable  in  length,  the  epimera  distinct,  the  posterior  coxae 
contiguous.  Legs  moderate  or  slender,  the  tibiae  not  spinulose  externally,  the 
anterior  deeply  emarginate  within  the  inner  spur  remote  from  the  apex.  Tarsi 
slender,  claws  simple. 

The  anterior  tarsi  of  the  males  have  two  joints  dilated  and  squamulose  beneath. 
As  above  constituted  the  tribe  contains  in  our  launa  two  <;roii])t^, 
separated  in  the  following  manner : 

Terminal  joint  of  palpi   more  or  less  cylindrical   and  obtuse  at  tip,  that  of  the 

labial  palpi  as  long  as  the  preceding Pogoni. 

Terminal  joint  of  palpi  slender,  acute  at  tij),  that  of  the  labial  pal])i  shorter  than 

the  preceding TiiKcni. 

In  addition  to  the  above  characters  the  form  of  the  paraglossas 
and  the  setae  of  the  ligula  add  some  weight  to  the  separation  of 
the  two  groups. 

The  group  Pogoni  contains  in  our  fauna  two  genera : 

Head  more  or  less  constricted  behind  the  eyes  or  transversely  impressed.     Elytra 
not  margined  at  base l*atrobus. 

Head  not  constricted  behind  the  eyes.     Elytra  usually  margined  at  base. 

I'OgOIIUM. 

This  group  has  been  the  subject  of  a  special  essay  by  Baron  Chaudoir, 
(Ann.  Belg.  xiv,  pp.  21 — 61),  in  which  he  divides  the  species  of  the 
former  genus  in  our  fauna  into  two  genera  Patrohus  and  P/(ttidius,  and 
the  latter  into  Pogomis,  Foyonistes  and  Diplochsefus.  I  have  given 
elsewhere  a  review  of  our  genera  and  species  in  which  will  be  found 
my  reasons  for  not  adopting  the  genera  suggested  by  Chaudoir,  ( Trans. 
Am.  Ent.  Soo.  v.  pp.  180  and  248). 


136  GEO.    H.    HORN,    M.  D. 

The  group  Trechi  contains  in  our  fiiuna  two  genera  which  have  the 
second  joint  of  the  antennae  somewhat  pubescent,  they  are  as  follows  : 

Head  with  distinct  eyes.     Anterior  tibiae  slightly  broader  to  tip,  the  emargination 

extending  nearly  to  the  middle  of  the  tibia TreclillS. 

Head  without  eyes.     Anterior  tibipe  slender,  the  eniarginatioji  at  apical  third. 

Anophtlialmus. 

Our  species  of  the  latter  genus  may  be  divided  in  two  series,  the  first 
contains  Tellkampfii  in  which  the  last  joint  of  the  maxillary  palpus  is 
very  distinctly  shorter  than  the  penultimate,  the  second  comprises  all  our 
other  species  with  the  same  joint  equal  to  or  even  a  little  longer  than 
the  preceding. 

The  tribe  Pogonini  of  the  present  essay  is  about  the  same  as  that 
intended  by  Lacordaire,  (Glenera  i,  p.  364),  less  the  genera  which  have 
been  properly  removed  by  Schaum  and  others.  The  latter  author 
however,  separates  the  two  groups  and  places  the  Pogoni  among  the 
Pterostichiui  rendering  that  tribe  heterogeneous  and  indefinable  while 
the  Trechi  are  found  near  Bembidiini. 

I  believe  that  Lacordaire  and  LeConte  are  correct  in  approximating 
the  Pogoni  and  Trechi  but  I  do  not  think  the  characters  separating  them 
are  of  tribal  value.  That  they  should  be  placed  near  Bembidiini  as  these 
authors  have  done  seems  to  me  proper  while  the  relationship  of  the 
Pogoni  with  Pterostichus  is  much  less  evident.  The  structure  of  the 
ligula  and  paraglossae  varies  but  little  between  the  Pterostichiui,  Patro- 
bini  and  Bembidiini. 

The  suture  between  the  mentum  and  its  support  is  often  entirely  obliter- 
ated especially  in  Anophthalmus,  and  is  very  indistinct  in" some  Patrohus 
although  sufficiently  marked  in  others,  and  in  nearly  all  Treclms. 

To  this  tribe  and  closely  related  to  the  Trechi  I  would  refer  the*genus 
Ooptems.  Lacordaire  places  the  genus  in  his  Cnemacanthides,  the 
Broscides  of  other  authors,  but  Putzeys  in  his  monograph  rejects  it. 
Guerin-Meneville  in  the  origin  placed  it  among  the  subulipalpi  and  was 
more  nearly  correct  than  LaQordaire.  Ooptertis  has  all  the  essential 
characters  of  the  group  Trechi  even  to  the  impressed  and  recurrent 
stria  and  it  seems  to  indicate  a  strong  attempt  to  unite  the  Pogonini 
and  Bembidiini. 

Tribe  XXIV.— Pterostichini. 

AntennsD  arising  under  a  distinct  frontal  ridge,  the  th!'ee  basal  joints  glabrous. 
Head  more  or  less  constricted  behind  the  eyes,  except  in  Amara,  and  with  two 
supra-orbital  setigerous  punctures,  clypeus  prolonged  beyond  the  base  of  the 
mandibles,  the  latter  without  setigerous  puncture  externally.  Maxillae  ciliate  or 
spinulose'  within,  hooked  at  tip  (except  Stomis  and  Agelcea),  the  palpi  of  moder- 
ate length  and  uf  variable  structure.     Mentum  broad,  of  variable  length,  usually

deeply  emarginate  and  toothed,  varying  to  a  simple  bisinuation ;  ligula  at  least 
moderate  in  size,  often  large,  more  or  less  free  at  tip  and  bisetose  (quadrisetose  in 
Myas),  the  paraglossse  slender  and  usually  longer  than  it,  sometimes  much  longer 
{Stomis,  Loxandrus),  the  palpi  variable  in  form  the  second  joint  sometimes  longer 
than  the  terminal.  Thorax  with  at  least  one  setigerous  puncture  at  the  side  and 
one  at  the  hind  angle.  Body  not  pedunculate,  (subpedunculate  in  some  Evarthrus), 
scutellum  distinct.  Elytra  narrowly  inflexed,  margin  strongly  interrupted  pos- 
teriorly and  with  a  well  marked  internal  plica,  disc  usually  with  dorsal  punctures. 
Prosternum  not  prolonged  at  tip,  margined  or  not.  Mesosternum  oblique  or  vertical 
in  front,  rather  widely  separating  the  coxse,  the  epimera  narrow  and  often  wider 
internally  than  externally.  Metasternum  and  side  pieces  variable  in  length,  the 
epimera  always  distinct,  posterior  coxa;  contiguous.  Middle  and  posterior  tibise 
variably  spinulose  externally,  the  anterior  slightly  so  near  the  tip,  the  latter 
broader  at  tip  deeply  emarginate  within,  the  inner  spur  situated  at  the  summit 
of  the  ehiargination." 

The  anterior  tarsi  of  the  male  have  three  joints  rather  broadly  dilated   and 
squamulose  beneath. 

As  here  intended  the  tribe  contains  several  groups  which  Lacordaire 
places  in  a  higher  rank.  Schaum  (Berl.  Zeitsehr.  18G0,  p.  17l>)>  extends 
the  limits  of  the  tribe  in  such  a  manner  that  it  would  be  impossible  to 
define  it,  as  he  includes  the  Platynini,  Patrobiiii  and  the  genus  Aritarctia. 
The  former  I  have  excluded  from  the  structure  of  the  elytra,  the  anterior 
tibia?  and  the  male  tarsi,  the  Patrobini  by  the  characters  especially  noted 
in  the  table  as  well  as  the  pubescence  of  the  antenna?  and  mode  of 
dilatation  of  the  male  tarsi,  while  Antarctia  belongs  also  near  Platynus. 
Schaum  has  already  scattered  Lacordaire's  Fseudo-Feronides,  and  of 
Section  viii  of  the  latter  author  (Genera  i,  p.  306),  we  have  but  two 
tribes  remaining  Trigouotomidex  and  Feronidea,  these  with  all  that 
remains  of  the  dismembered  Stomides  constitute  the  tribe  of  the  present 
essay  which  may  be  divided  into  three  groups.* 
Mentum  feebly  emarginate,  sometimes   simply  bisinuate.  the   maxilLip    hooked 

at  tip TiufiONOToiM:. 

Mentum  emarginate  and  toothed. 

Maxillffi  hooked  at  tip Pterostichi. 

Maxilla;  not  hooked  at  tip Stomks. 

Chaudoir  has  already  indicated  (Bull.  Mosc.  1872),  some  changes  in 
the  composition  of  the  first  group,  the  second  is  the  only  one  represented 
in  our  fauna  and  the  third  contains  as  far  as  I  know  but  two  genera, 
Stomis  and  Age/sea.  From  the  Pterostichi  (Feronides  Lac),  in  addition 
to  the  eliminations  already  made  I  would  exclude  Zahrus  which  is  by 
far  more  closely  to  the  Harpalinae  than  to  the  present  tribe  although 
through  it  and  Amara  the  relationship  is  approximated. 

«  From  the  characters  given  of  the  tribe  Drimostomides  by  Chaudoir,  (Ann. 
Belg.  xv),  it  seems  probable  that  it  might  form  a  fourth  group  of  the  present  tribe.

138  GEO.    H.    HORN,    M.  D. 

Among  the  genera  of  the  first  group  Lacordaire  places  Amhlytelus 
Erichs.  After  a  careful  examination  of  the  species  on  which  it  is 
founded  I  believe  that  author  to  be  entirely  correct.  It  is  however  an 
exception  in  the  entire  tribe,  as  far  as  I  know,  in  having  the  fourth  tarsal 
joint  bilobed  on  all  the  feet.  The  general  appearance  of  the  species  is 
rather  that  of  a  Callidide  but  the  entire  elytra  with  the  well  marked 
internal  plica  indicate  the  correctness  of  its  reference  here.  The  group 
Trigonotomae  seems  however  rather  unnatural  and  should  in  all  probability 
be  separated.     Amhlytelus  will  in  any  event  represent  a  distinct  group. 

The  group  Pterostichi  is  the  only  one  represented  in  our  fauna  and 
the  number  of  the  genera  must  remain  the  subject  of  discussion  until 
a  thorough  monograph  shall  have  fixed  their  limits.  Those  of  our  own 
fauna  require  discussion  here. 

In  order  that  the  reader  may  have  some  point  of  departure  from 
which  to  follow  the  argument  I  reproduce  the  table  of  genera  given 
by  Dr.  LeConte  in  his  last  discussion  of  the  subject,  (Proc.  Acad.  1873, 
p.  302),  to  which  I  add  Myas  and  Amara. 

Last  joint  of  palpi  dilated.     Mentum  tooth  obtuse Myas. 

Last  joint  of  palpi  cylindrical  or  slightly  oval. 

Mandibles  striate;  elytra  with  one  dorsal  puncture Evarthrus. 

Mandibles  not  striate. 
Mentum  tooth  emarginate. 
Ligula  carinate. 

Metathoracic  episterna  long Lophoglossus. 

Metathoracic  episterna  short Holciophorus. 

Ligula  not  carinate. 

Front  tarsi  of  %,  normally  dilated. 

Second  joint  of  labial  palpi  bisetose Pterostichus. 

Second  joint  plurisetose Amara. 

Front  tarsi  of  %,  obliquely  dilated Loxandrus. 

Mentum  tooth  entire Piesmus. 

In  Myas  the  characters  are  undoubtedly  valid  and  in  addition  it  might 
be  added  that  the  ligula  is  quadrisetose  in  front,  a  character  figured  by 
Migneaux  but  not  mentioned  by  Duval.  The  elytra  have  no  dorsal 
puncture  and  the  mandibles  are  obliquely  striate. 

The  striation  of  the  mandibles  which  seems  to  have  been  a  character  of 
last  resort  in  the  separation  of  Evarthrus  will  not  by  any  means  hold 
good  with  many  species  of  Pterostichus,  {rostratus,  tumescens,  mancus, 
coracinus,  etc.),  which  have  the  mandibles  more  deeply  striate  than  very 
many  Evarthrus. 

The  species  of  Evarthrus  are  readily  separable  into  two  series,  the 
first  has  the  penultimate  joint  of  the  labial  palpi  longer  than  the  last 
and  with  three  or  four  long  setae,  the   second  has  the  terminal  joint 


AMERICAN    COLEOPTERA.  139 

longer  and  the  penultimate  merely  bisetose,  the  mandibles  are  decidedly 
sulcate  in  the  first  series  (species  1 — 12),  and  often  very  feebly  so  in 
the  second,  (species  13 — 25,  Synopsis  loc.  cit.). 

The  carination  of  the  ligula  has  no  value  as  a  generic  character,  in 
fact  the  carinate  ligula  occurs  in  many  places  in  Pterostichus,  (varying  in 
degree),  especially  in  the  flatter  species  from  the  Pacific  region. 

The  manner  of  the  dilatation  of  the  tarsi  in  Loxandrus  serves  to 
separate  it  sufficiently  in  a  group  where  the  characters  are  so  feeble. 

The  plurisetose  second  joint  of  the  labial  palpi,  and  its  consequently 
greater  length  than  the  third,  serves  to  separajte  Amara  from  all  the 
other  genera  except  the  first  or  genuine  series  of  Evarthrus. 

The  mentum  tooth  seems  also  to  have  lost  value  as  many  Pterostichus  in 
Europe  have  an  obtuse  tooth  as  in  our  submarginatus,  while  it  appears  to 
have  escaped  notice  that  P.  honestus  Say,  has  a  rather  long  acute  tooth. 

While  retaining  M^as  and  Loxandrus  as  distinct  on  characters  which 
are  undoubtedly  valid  the  other  genera  require  some  modification. 

The  following  table  represents  the  conclusions  which  I  have  arrived  at ; 

Terminal  joint  of  palpi  dilated.     Elytra  without  dorsal  puncture Mjas. 

Terminal  joint  of  palpi  cylindrical  or  slightly  oval. 
Anterior  tarsi  of  male  normally  dilated. 

Terminal  joint  of  palpi  as  long  as  or  longer  than  the  penultimate,  the  latter 

bisetose  in  front Pteroslichiis. 

Terminal  joint  of  paljii  shorter  than  the  penultimate,  the  latter  ))Iurisetose 
in  front. 

Elytra  with  ©ne  dorsal  puncture Evarflirus. 

Elytra  without  dorsal  puncture Amara. 

Anterior  tarsi  of  male  obliquely  dilated liOxaiidnis. 

By  this  arrangement  Holciophorus,  Lophoglossus,  Piesmus  and  the 
second  series  of  Evarthrus  revert  to  Pterostichus.  Amara  is  intended 
in  its  most  comprehensive  sense  although  some  of  its  groups  have 
characters  of  apparently  greater  value  than  those  used  above  in  the 
separation  of  genera.  Loxandrus  is  the  nearest  approach  in  our  fauna 
to  the  Trigonotomi». 

Tribe  XXV.— Licinini. 

Antennae  slender,  moderately  long,  arising  under  a  distinct  frontal  plate,  the 
three  basal  joints  glabrous  (two  in  Badister).  Head  short,  moderately  stout,  witli 
two  supra-orbital  setse,  clypeus  short  not  prolonged  between  the  mandibles,  emar- 
ginate  and  exposing  the  basal  membrane  of  the  labrum,  with  a  setigerous  ptine- 
ture  in  each  angle.  Labrum  usually  short,  emarginate,  longitudinally  impressed. 
Eyes  moderate  in  size  not  very  distant  from  the  mouth  except  in  Diccelus  where 
they  are  small  and  very  distant.  Mandibles  stout  more  or  less  arcuate,  tips  usually 
obtuse  except  in  Diccehis  where  they  are  feebly  arcuate  and  acute.  Maxillse  hooked 
at  tip  ciliate  within,  the  outer  lobe  rather  slender,  biarticulate,  the  palpi  moderate 
in  length,  the  last  joint  variable  in   form.     Mentum  deeply  emarginate  without 


140  GEO.    H.    HORN,    M.  D. 

tooth  (in  our  genera),  the  ligula  and  paraglossse  variable  in  form,  the  former 
bisetose  at  tip,  the  palpi  moderate,  the  last  joint  variable  in  form  but  equal  in 
length  to  the  preceding  which  is  bisetose  in  front.  Thorax  variable  in  form,  with 
one  (rarely  two)  lateral  setigerous  punctures  and  one  near  (rarely  at)  the  hind 
angle.  Body  not  pedunculate.  Elytra  margined  at  base,  sides  at  most  moderately 
inflexed  the  margin  rarely  {Licinus)  sinuate,  not  interrupted  and  without  internal 
plica,  surface  striate  and  with  one  {Diplochila)  two  (Badister)  or  no  dorsal  punc- 
ture (Diccelus).  Prosternum  obtuse  at  tip.  Mesosternum  concave  in  front,  the 
epimera  very  narrow.  Metasternal  epimera  distinct.  Posterior  eoxse  contiguous. 
Anterior  tibiae  deeply  emarginate  within,  the  middle  and  posterior  tibise  slightly 
spinulose  or  ciliate  externally.     Tarsi  slender,  claws  simple. 

The  anterior  tarsi  of  the  males  have  three  joints  rather  broadly  dilated,  densely 
spongy  pubescent  and  ciliate  at  the  sides.  In  Licinus  however  there  are  but  two 
dilated  joints. 

This  tribe  contains  but  few  genera  and  all  authors  seem  pretty  well 
in  accord  as  to  its  composition  and  it  is  a  surprising  thing  to  find 
Ambli/stomus  placed  here  by  Bedel,  (Ann.  Fr.  1879,  Suppl.  p.  58), 
a  genus  whose  affinities  ai-e  so  plainly  with  the  Harpalini. 

The  affinities  of  the  tribe  are  not  well  marked.  The  form  of  the  head 
recalls  some  Harpalini,  Diplochila  resembles  superficially  Microcephalus 
of  the  Pterostichini,  while  Dicsehis  has  some  analogy  with  Be/ecinm. 

The  genera  proper  to  our  fauna  are  three  in  number,  Licinus  silplioides 
has  in  one  or  two  instances  been  found  but  under  circumstances  which 
induce  me  to  believe  that  it  had  been  introduced,  for  convenience  how- 
ever I  add  it  to  the  table. 

Antennae  with  three  basal  joints  entirely  glabrous. 

Eighth  and  ninth  striae  of  elytra  very  closely  approximated.    The  third  interval 

with  a  dorsal  puncture,  apex  very  feebly  sinuate Diplochila. 

Eighth  and  ninth  striae  distant. 
Elytra  not  sinuate  at  apex. 

Seventh  interval  more  or  less  carinate  at  base Dicselus. 

Elytra  strongly  sinuate  at  apex. 

Seventh  interval  not  carinate Liiciiius. 

Antenna?  with  two  basal  joints  only  glabrous.  Eighth  and  ninth  striae  not 
approximated,  third  interval  with  two  dorsal  punctures,  apex  not  sinu- 
ate  Badister. 

Diplochila  has  the  terminal  joint  of  the  palpi  more  or  less  cylindrical 
and  obtuse  at  tip.  Dicselus  and  Licinus  have  the  last  joint  more  or  less 
triangular  and  in  Badister  somewhat  oval  and  flattened. 

To  this  tribe  should  be  referred  the  Australian  genus  Dicrochile.  Its 
front  closely  reproduces  that  of  our  Diplochila  while  the  bifid  labrum 
is  the  legitimate  development  of  the  latter  genus.  The  tarsi  of  the 
male  are  moreover  similarly  dilated  while  the  general  '  aspect  of  the 
species  before  me  {D.  Goryi  Bdv.),  is  that  of  an  elongate  Badister. 
Dicrochile  has  the  tip  of  the  mandibles  emarginate. 


AMERICAN    COLEOPTERA.  141 

Tribe  XXVL— Platynini. 

AntennEe  slender  rarely  (Perigona)  slightly  thickened,  arising  below  a  slight 
frontal  ridge,  the  condyle  exposed,  three  basal  joints  glabrous,  first  joint  not  long, 
second  usually  short  rarely  as  long  as  the  third  in  which  case  neither  is  elongate, 
third  moderate  in  length  usually  longer  than  the  others,  but  rarely  equal  to  or 
shorter  than  the  fourth.  Eyes  moderately  prominent,  close  to  the  mouth  beneath. 
Head  oval,  rarely  elongate,  eyes  not  very  distant  from  the  thorax,  two  supra-orbital 
setse,  front  slightly  narrowed  before  the  eyes,  clypeus  moderately  prolonged  and 
with  a  setigerous  puncture  each  side.  Labrum  moderately  prominent  usually 
truncate  in  front  and  sexsetose,  rarely  deeply  emarginate.  Mandibles  moderately 
prominent,  feebly  arcuate,  acute  at  tip,  without  external  seta.  Maxillae  hooked 
at  tip,  ciliate  or  spinulose  within,  outer  lobe  biartieulate,  palpi  moderate  in  length, 
the  terminal  joint  variable,  rarely  securiform.  Mentum  deeply  emarginate,  toothed 
or  not,  basal  membrane  more  or  less  prominent,  ligula  very  variable  in  form, 
bisetose  in  front,  the  paraglossse  variable  in  form  and  extent  of  union  with  the 
ligular,  palpi  moderate,  the  last  joint  somewhat  variable  in  form,  the  penultimate 
bisetose  in  front.  Thorax  variable,  sides  with  a  setigerous  puncture,  a  second  at 
the  hind  angle  when  the  latter  is  distinct  or  in  front  of  the  angle  when  it  is  obtuse 
or  rounded.  Elytra  margined  at  base,  sides  narrowly  inflexed,  margin  entire 
without  internal  plica,  apex  obliquely  sinuate,  sometimes  deeply,  or  even  barely 
perceptibly,  dorsal  punctures  usually  present,  rarely  {Pristovychus)  wanting, 
surface  striate,  the  eighth  stria  distant  from  the  margin  except,  in  Perigona. 
Prosternum  not  prolonged  at  tip.  Mesosternal  epimera  narrow.  Metasternal 
epimera  distinct,  posterior  coxse  contiguous.  Legs  slender,  the  femora  sometimes 
thickened,  tibise  slender,  not  sulcate  externally,  the  middle  and  posterior  slightly 
ciliate  externally,  the  anterior  slender  emarginate  within,  spurs  moderate  in 
length.  Tarsi  slender,  the  joints  often  sulcate  on  their  outer  side  the  fourth  entire, 
emarginate  or  bilobed.     Claws  simple,  finely  serrate  or  pectinate. 

The  males  have  the  anterior  tarsi  with  three  joints  feebly  dilated  and  squamu- 
lose  beneath. 

The  tribe  as  here  intended  is  the  equivalent  of  Lacordaire's  Aneho- 
menides  from  which  however  some  genera  have  been  removed,  Loxo- 
crepis  and  Monolohus  to  the  Carabinae,  Oxyglossus  and  Stcnognathus 
to  the  Lebiini. 

As  a  part  of  the  tribe,  constitutintr  probably  a  distinct  group  I  would 
suggest  the  addition  of  Antnrctia  and  Geohsenus  and  I  entirely  agree 
with  C.  G.  Thomson  in  adding  Masoreim.  I  can  not  understand  why 
Chaudoir  (Bull.  Mosc.  1870),  associates  in  a  complex,  (it  can  not  be 
called  a  tribe)  Masoreus,  the  Tetragonoderides,  Nemotarsus  and  the 
Sarothrocrepides. 

Perigona  seems  also  better  placed  here  than  elsewhere  and  appears  to 
be  a  lead  towards  the  Trechini  in  the  same  manner  that  Olisthopus  does 
to  the  Lebiini. 

A  study  of  the  form  of  the  ligula  and  paraglossae  of  those  genera 
which  are  acknowledged  on  all  sides  to  be  undoubted  members  of  the 
present  tribe  Flafynui^^  Calathm^  and  Olhtliopus,  seems  to  nie  to  show 


142  GEO.    H.    HORN,    M.  D. 

what  little  value  these  organs  have  in  the  formation  of  tribes  and  groups 
of  genera.  The  ligula  of  OHsthopus  is  very  plainly  that  of  many  Lebiides, 
Platijnus  reproduces  very  closely  that  of  Pterosticlius,  Calathus  proper 
is  as  nearly  as  possible  intermediate  between  the  two  while  the  section 
Pristodactt/la  is  a  modification  of  Flatynus.  The  tip  of  the  ligula  is  free 
in  Platynus  and  Pristodactyla  and  not  free  in  the  other  genera. 

The  mentum  tooth  also  seems  to  furnish  characters  of  an  evanescent 
nature.  In  some  Platynus^  especially  those  in  which  the  hind  angles  of 
the  thorax  are  distinct  {brunneomarginatus,  ovipennis,  etc.),  the  tooth 
is  longitudinally  impressed  and  emarginate  at  tip,  while  in  the  Ayonum 
type  the  tooth  is  very  obtuse.  The  same  variation  is  observed  in  Calathus, 
some  having  quite  an  acute  tooth,  others  even  bifid. 

The  tribe  seems  to  be  divisible  primarily  into  three  groups  by  the 
following  characters : 

Eighth  elytral  stria  distant  from  the  margin  and  not  deeply  impressed. 

Thorax  truncate  or  emarginate  at  base Platyni. 

Thorax  slightly  lobed  at  middle  of  base Masoref. 

Eighth  elytral  stria  confluent  with  the  margin  in  its  basal  half,  deeply  impressed 
and  attaiiiing  the  suture Perigoni. 

Group  Platyni. 
This  group  might  easily  be  separated  in  many  minor  subdivisions  by 
including  the  genera  not  represented  in  our  fauna. 
The  following  genera  occur  with  us : 

Ungues  more  or  less  serrate.     Mentum  toothed. 

Tarsi  glabrous  above.     Elytra  with  dorsal  punctures Calatliiis. 

Tarsi  hairy  above.     Elytra  without  dorsal  punctures Pristonycliiis. 

Ungues  not  serrate.     Elytra  with  dorsal  punctures. 

Mentum  toothed Platynus. 

Mentum  not  toothed Olistliopus. 

OHsthopus  is  represented  in  the  Atlantic  region  by  two  species,  the 
other  genera  occur  on  both  sides  of  the  continent.  Of  Pristom/chus 
two  species  are  known  both  of  them  identical  with  European  forms 
(complunatus  and  terricola),  and  have  probably  been  introduced,  the  first 
mentioned  being  rather  widely  spread  by  commerce  over  the  globe. 

Anchus  Lee,  founded  on  Plutynus  pusillus  is  not  distinct  from  Platy- 
nus. The  species  is  our  equivalent  for  Anchomenus  ohlongulus  Fab., 
of  Europe,  and  may  even  be  specifically  identical,  the  only  striking  diflfer- 
ence  between  the  two  being  in  the  slightly  wider  thorax  of  our  species. 

To  this  group  I  would  refer  Wollaston's  genus  Zargm.  The  facies 
of  the  species  is  not  unlike  that  of  certain  of  our  Platynvs  {stria tits, 
snJcatus).  The  clypeus  is  membranous  at  middle  even  to  a  greater 
extent  than  in  DIcrochik  while  the  labrum  is  also  bifid.      Chaudoir  is 


AMERICAN    COLEOPTERA.  143 

willing  to  believe  Zurgus  allied  to  DicrochlJe  evidently  from  the  form 
of  labrum,  but  it  is  really  a  true  Plafynus  form  allied  to  Olisthopiis  the 
ligular  characters  of  which  it  exaggerates. 

Lestignuthus  is  also  a  member  of  the  group.  The  description  of  the 
ligula  heretofore  given  is  certainly  very  erroneous.  The  ligula  is  in 
great  part  membranous  with  merely  a  small  urn-shaped  piece  at  the  tip 
corneous,  the  paraglossae  are  very  distinct  and  longer  than  the  ligula. 
By  comparing  the  figure  which  I  give  of  the  parts  it  will  be  observed 
that  the  ligula  does  not  differ  essentially  from  Plafi/vus.  The  tip  of 
the  ligula  is  connected  with  the  paraglossae  by  a  very  thin  transparent 
membrane. 

In  the  species  of  Lesfignathus  before  me  I  observe  that  the  suture 
between  the  mentum  and  its  support  is  as  completely  obliterated  as  in 
Enceladus.  It  is  the  only  instance  known  to  me  of  this  character  in 
the  present  or  the  preceding  tribe. 

For  the  opportunity  of  examining  Zargus  Schaumii  Woll.,  and 
Lestignathus  Simsonii.  Bates,  I  am  indebted  to  Mr.  E.  W.  Janson. 

Group  Masorei. 
No  representative  of  this  group  occurs  in  our  fauna.  The  latest 
revision  of  the  genera  is  by  Chaudoir,  (Bull.  Mosc.  1876),  in  which 
contrary  to  his  usual  custom  he  says  but  little  of  the  parts  of  the  mouth. 
The  fullest  accounts  of  these  are  by  Lacordaire  and  Duval,  and  both  are 
inaccurate  in  the  description  of  the  ligula  and  paraglossae.  In  Masoretis 
Wetterhalli  the  ligula  is  triangular,  truncate  in  front,  the  paraglossae 
rather  broad  and  not  connate  with  the  ligula  to  the  tip  but  folded  behind 
it  as  represented  in  the  accompanying  dissection.  It  is  evident  that 
Lacordaire  and  Duval  have  either  dissected  a  Perigona  or  that  the  latter 
author  copied  from  the  former  who  considered  Perigona  a  synonym  of 
Masoreus.  In  his  tribe  of  Masoreides  Chaudoir  places  seven  genera 
some  of  which  seem  to  me  to  belong  to  the  next  group. 

Group  PerigonjK. 

This  group  is  represented  by  one  genus  Perigona  which  has  for  its 
synonyms  Trechicus,  Nestra  and  Spathinus.  The  mentum  has  its  epi- 
lobes  prolonged  to  an  acute  spine,  the  emargination  is  deep  without  tooth. 
The  ligula  is  narrow  and  truncate  at  tip,  the  paraglossae  slender  and 
a  little  longer  than  the  ligula,  and  united  with  the  latter  by  a  thin 
almost  transparent  membrane  which  extends  from  the  base  of  the 
paraglossae  to  the  tip  of  the  ligula. 

The  antennae  are  rather  stout  beyond  the  third  joint  and  the  second 
is  as  Ions  as  the  third. 


144  GEO.    H.    HORN,    M.  D. 

There  is  certainly  no  reason  why  Perigona,  should  be  placed  as  a 
Truncatipenne.  The  two  supra-orbital  setae  remove  it  from  association 
with  the  Harpalide  series.  Taking  its  entire  organization  it  seems  better 
placed  in  the  present  tribe  than  anywhere  else. 

Tribe  XXVII.— Anchbnoderini. 
Head  oval  or  rounded,  not  prolonged  nor  constricted  to  a  narrow  neck;  with 
two  supra-orbital  setigerous  punctures.  Antennse  slender,  not  thicker  externally. 
Eyes  variable  in  prominence  but  always  close  to  the  buccal  fissure  beneath. 
Thorax  more  or  less  cordiform  the  lateral  margin  distinct,  setigerous  punctures  at 
side  striated  the  one  in  front  of  middle  the  second  at  the  hind  angle  (except  in 
Lachnophorus  where  it  is  slightly  in  front).  Elytra  feebly  margined  at  base,  the 
lateral  margin  distinct,  apices  rounded.  Scutellum  and  scutellar  stria  distinct. 
Tarsi  slender,  fourth  joint  simple.  Claws  simple.  Posterior  coxae  contiguous. 
Body  above  pubescent  or  pilose. 

In  the  above  characters  will  be  found  all  that  will  define  the  genera 
placed  here.  With  other  genera  the  tribe  might  possibly  be  more 
properly  divided  in  three  but  for  the  present  they  will  be  considered 
groups  forming  an  osculant  tribe. 

These  groups  are  as  follows  : 

Antennse  with  four  glabrous  joints. 

Thorax  ovate,  lateral  margin  obtuse,  the  posterior  setigerous  puncture  in  front 

of  the  basal  angle.     Body  subpedunculate Lachnophori. 

Last  joint  of  palpi  ovoid,  suddenly  acuminate  at  tip,  the  surface  pubescent. 

Elytra  with  three  dorsal  punctures Liacliuoplioriis^ 

Last  joint  of  palpi  conical,  gradually  narrowed  to  tip,  the  surface  glabrous. 

Elytra  without  dorsal  punctures Euphorticus. 

Thorax  cordiform,  lateral  margin  acute,  the  posterior  setigerous  puncture  at  the 

hind  angle.     Body  not  pedunculate Anciionoderi. 

Last  joint  of  palpi  gradually  narrowed  to  tip  and  slightly  oval.     Elytra  with 

three  feeble  dorsal  punctures Ancliouoderiis. 

Antennse  with  three  basal  joints  glabrous.     Thorax  cordate  margin  acute,  the 

hind  angle  with  Setigerous  puncture Atrani. 

Palpi  as  in  Anchonoderus.     Dorsal  punctures  not  evident Atranus. 

The  structure  of  the  antennae  of  the  first  two  tribes  seems  to  have 
been  overlooked.  The  joints  2—4  are  not  absolutely  glabrous  in  the 
strict  acceptation  of  the  term  but  they  are  devoid  of  the  fine  punctuation 
and  pubescence  which  covers  the  following  joints. 

From  the  characters  above  given  it  will  be  evident  that  the  Lachno- 
phori osculate  closely  with  the  Egini  and  the  Atrani  with  the  Platynini. 
while  the  Anchonoderi  are  intermediate  between  the  other  two  groups. 

Group  Lachnophori. 
Eyes    large   moderately   prominent.     Head    oval,   sometimes   slightly 
constricted   behind   the  eyes,  front  more  or  less   deflexed.     Elytra  not 
margined  at  base,  the  apex  with  very  feeble  sinuation  in  Lachnophorus 


AMERICAN    COLEOPTERA.  145 

or  rounded  in  Euphorticus,  the  striae  entire,  the  eighth  stria  distant  from 
the  margin  with  very  distinct  ocellate  punctures  in  the  former  genus,  not 
distinct  in  the  latter.  The  setigerous  punctures  of  the  side  of  the  thorax 
are  two  in  number,  the  first  situated  at  the  point  of  greatest  width,  the 
second  midway  between  this  and  the  hind  angle.  The  thorax  is  not 
wider  than  the  head  between  the  eyes. 

The  males  have  the  anterior  tarsi  slightly  dilated  and  from  the 
anterior  angle  at  the  inner  side  of  the  joints  1 — 3  proceeds  a  brush 
of  fine  silken  hair. 

To  the  two  genera  above  named  it  will  probably  be  necessary  to  add 
Lasiocera.  Euphorticus  n.  g.  is  founded  on  Lachn.  jmhescenx  Dej.,  and 
the  only  characters  separating  it  are  those  given  in  the  table. 

•Group  Anchosoderi. 

The  eyes  are  not  prominent.  Head  oval  slightly  narrowed  behind 
the  eyes,  front  horizontal.  Elytra  not  margined  at  base,  the  apices 
rounded,  surface  striate,  eighth  stria  distant  from  the  margin  and  with  the 
ocellate  punctures  feeble,  dorsal  punctures  three  but  fine  and  indistinct. 
Thorax  cordate  as  wide  as  the  head,  lateral  setigerous  punctures  situated 
at  the  point  of  greatest  width  and  in  the  hind  angle. 

The  anterior  tarsi  of  the  males  have  three  joints  slightly  dilated  and 
with  squamiform  papillae  and  ciliate  at  the  side. 

Anchonoderus  and  probably  Camptofoma  enter  this  group.  The  former 
genus  alone  is  represented  in  our  fauna  by  one  species  from  Texas. 

Group  Atrani. 

Head  oval,  more  elongate  than  AnihonoderuR  the  eyes  not  prominent. 
Antennae  with  but  three  joints  glabrous,  the  fourth  punctured  and 
pubescent  as  the  fifth.  Thorax  cordate,  a  little  broader  than  the  head, 
the  setae  in  the  normal  position  at  the  side  and  in  the  hind  angles. 
Elytra  margined  at  base,  the  apices  rounded,  surface  striate,  the  ocellate 
punctures  well  marked,  dorsal  punctures  not  distinct. 

The  sexual  characters  are  as  in  Anchonoderus. 

This  group  contains  in  our  fauna  but  one  genus  Atranns  Lee.  The 
species  A.  puhescens  Dej.,  was  originally  described  as  an  Anchomenus ; 
separated  by  LeConte  with  its  present  generic  name  it  was  placed  among 
the  Chlaeniini.  Chaudoir  first  suggested  its  removal  from  that  position 
to  that  in  which  it  is  now  found. 

Tribe  XXVIII.- Ctenodactylini. 

Antennffi  slender,  base  free,  three  basal  joints  glabrous,  first  joint  stouter,  as 
long  as  the  next  two,  ,S— 11  equal  or  nearly  so.  Head  rhomboidal,  prolonged 
behind  the  eyes  and  narrowed  to  a  distinct  neck,  front  with  two  supra-orbital 
setse;  clypeus  moderately  prolonged,  a  setigerous  puncture  each  side.     Eyes  large

14(j  GEO.    H.    HORN,    M.  D. 

moderately  prominent,  narrowly  separated  from  the  mouth  beneath.  Labrum 
transverse,  feebly  emarginate,  margin  sexsetose.  Mandibles  arcuate  acute  at  tip, 
not  prominent.  Maxillse  slender,  ciliate  and  spinous  within,  the  outer  lobe  slender 
and  with  two  equal  joints,  the  palpi  slender,  the  terminal  joint  elongate-oval  and 
acute. ,  Mentum  deeply  emarginate,  toothed,  (except  in  Pionycha),  ligula  moder- 
ately prominent,  the  tip  bilobed  or  narrowed  and  bisetose,  paraglossse  slender 
and  acute  usually  longer  than  the  ligula,  palpi  slender,  last  joint  oval  acute,  the' 
penultimate  bisetose  in  front.  Thorax  elongate,  narrower  thfVn  the  head,  margin 
feeble,  sides  with  a  setigerous  puncture  near  the  middle  and  at  the  hind  angle. 
Body  subpedunculate,  scutellum  not  prolonged  between  the  elytra.  Elytra  oblong- 
oval,  not  margined  at  base,  lateral  margin  distinct  and  entire,  without  internal 
plica,  apices  rounded  without  sinuation,  disc  striate,  third  interval  with  three 
indistinct  dorsal  punctures.  Prosternum  slightly  prolonged  at  tip.  Mesosternum 
oblique,  the  epimera  very  narrow.  Metasternal  epimera  distinct,  posterior  coxae 
contiguous.  Legs  slender,  middle  and  posterior  tibife  slightly  ciliate  externally, 
the  anterior  emarginate,  its  spurs  very  small.  Tarsi  slender,  the  first  joint  as  long 
as  the  next  two  which  are  oval,  the  fourth  broad,  deeply  bilobed  and  j^apillose 
beneath,  claws  pimple  dentate  or  pectinate. 

The  tarsi  are  alike  in  the  sexes.  The  males  have  one  seta  on  each  side  of  the 
apex  of  the  last  ventral  segment,  the  females  two. 

The  tribe  as  here  constituted  contains  not  only  the  Ctenodactylides  of 
Lacordaire  but  also  his  Trigonodactylides. 

Two  groups  may  be  indicated. 
Thorax  narrow,  elongate.     Ligula  slender  usually  narrowed  in  front. 

CTENODACTyL.JE. 

Thorax  nearly  or  fully  as  wide  as  long.     Ligula  bilobed  at  tip HexagonijE. 

The  Ctenodactyl/E  alone  are  represented  in  our  fauna  by  Lepto- 
trachehhs  which  occurs  in  the  Atlantic  region. 

Regarding  the  Hexagon:^  as  typified  by  Hexagonia  (=  Trigono- 
dactyla)  the  only  genus  known,  it  can  only  be  said  that  it  is  remarkable 
that  such  an  extraordinary  error  should  have  been  allowed  to  pass  current 
from  one  author  to  another  as  has  been  done  in  the  description  of  the 
maxilla.  After  having  carefully  dissected  the  mouth  of  Trigonodactyta 
the  parts  were  placed  under  the  microscope  and  an  appearance  of  the 
tip  of  the  maxilla  seemed  to  indicate  that  it  was  really  terminated  by 
a  moveable  hook.  3Iy  custom  however  has  been  in  doubtful  cases  to 
surround  the  parts  with  a  drop  of  water  on  glass  when  all  sutures  and 
other  lines  become  apparent.  Without  wishing  to  describe  in  detail  the 
structure  of  the  maxilla  the  reader  is  referred  to  the  figure. 

It  will  be  observed  in  the  two  groups  above  indicated  that  the  paraglossae 
arise  apparently  by  their  base  from  the  side  of  the  ligula  in  the  Cteno- 
dactyli,  but  are  prolonged  to  the  base  of  the  ligula  in  the  Trigonodactyli. 
The  difference  is  however  more  apparent  than  real.  If  the  ligula  bo 
observed  from  the  inner  side  the  paraglossae  will  be  found  adherent  to 
that  side,  their  outer  edge  being  very  close  to  that  of  the  ligula  itself. 


AMERICAN    COLEOPTERA.  I'AT 

The  tribe  has  affinities  in  two  directions,  the  first  group  with  the 
Odacanthini,  the  second  with  the  Dryptini.  Schaum  (Ins.  Deutschl.  i, 
p.  251),  places  the. genera  of  the  present  tribe  in  his  group  Odacanthidfe 
which  inchides  also  the  Odacanthini  and  Anchonoderini  of  the  present 

essay. 

Tribe  XXIX.— Odacanthini. 
Antennfe  slender,  free  at  base,  first  joint  as  long  as  the  next  two,  three  basal 
joints  glabrous.  Head  oval  more  or  less  elongate,  prolonged  behind  the  eyes  and 
narrowed  to  a  neck,  two  supra-orbital  setse,  elypeus  moderately  prolonged,  trun- 
cate, a  setigerous  puncture  on  each  side.  Eyes  large  moderately  prominent,  very 
narrowly  separated  from  the  mouth  beneath.  Labrum  moderately  prominent, 
sexsetose  in  front.  Maxillse  slender,  ciliate  and  spinous  within,  outer  lobe  biarticu- 
late  with  equal  joints,  palpi  slender,  the  last  two  joints  nearly  equal  the  terminal 
slightly  fusiform,  acute  at  tip.  Mentum  emarginate  and  toothed,  ligula  usually 
truncate  at  tip  and  bisetose,  the  apex  free  for  a  short  distance,  the  paraglossfe  small 
rarely  longer  than  it,  the  palpi  slender  the  last  joint  slightly  fusiform  acute  at 
tip,  the  penultimate  not  longer  than  it  and  bi-  rarely  trisetose  ir^  front.  Thorax 
narrow,  the  margin  usually  feeble  or  even  entirely  obliterated,  a  seta  near  the 
middle  of  the  side,  a  second  at  the  hind  angle  which  is  often  feeble.  Body  sub- 
pedunculate,  scutellum  not  projecting  between  the  elytra.  Elytra  oblong-oval, 
base  not  margined,  sides  narrowly  inflexed,  margin  entire  without  internal  plica, 
the  apices  truncate,  sometimes  rather  obliquely.  'Prosternum  not  prolonged. 
Mesosternum  oblique  the  epimera  very  narrow.  Metasternal  epimera  distinct, 
posterior  coxa;  contiguous.  Legs  slender,  the  middle  and  posterior  tibia;  slightly 
ciliate  externally,  the  anterior  emarginate  within,  the  spurs  small.  Tarsi  usually 
slender  rarely  flattened,  the  fourth  joint  at  most  feebly  emarginate.  Claws  simple. 
The  anterior  tarsi  exhibit  no  ditierences  in  the  two  sexes. 
In  all  the  genera  there  will  be  observed  numerous  punctures,  bearing 
short  erect  hairs,  situated  either  in  the  second  stria  or  the  third  interval. 
The  tribe  as  here  constituted  js  the  same  as  in  Lacordaire  except  that 
Stenochila  is  excluded  and  Calophsena  added.  There  is  a  close  rela- 
tionship between  this  tribe  and  the  Ctenodaetylini,  and  they  are  united 
by  some  authors,  the  only  difference  of  moment  being  that  the  elytra  are 
here  truncate  and  there  entire. 

With  the  Lebiini  and  Dryptini  there  is  also  a  very  close  relationship, 
the  characters  separating  the  present  tribe  from  the  former  are  certainly 
not  very  well  marked  if  we  admit  the  Lacordairean  aggregation.  The 
Lebiini  of  the  present  essay  is  composed  of  the  Lebiides  of  Lacordaire 
excluding  especially  Agra,  the  Pericalides  and  Mormolyce.  Two  of  these 
"•enera  have  an  elono;ated  head  and  thorax  and  all  have  truncate  elytra. 

I  can  find  no  constant  character  separating  the  Odacanthini  from  the 
Dryptini.  excepting  in  the  form  of  the  labial  palpi.  For  this  reason 
I  remove  Stenochila  which' has  not  only  the  long  joint  of  the  antennae 
but  also  the  penultimate  joint  of  the  labial  palpi  plurisetose.  Calophsena 
however  has  the  palpi  and  antennae  of  the  present  tribe. 


148  GEO.    H.    HORN,    M.  D. 

The  only  genus  which  occurs  in  our  fauna  is  Casnonia  represented 
by  two  species  pensylvanica  and  ludoviciana,  in  which  the  setigerous 
punctures  of  the  second  stria  are  very  indistinct  and  rarely  more  than 
four  in  number.  The  last  mentioned  species  is  remarkable  in  having 
the  thoracic  margin  rounded  and  the  sutures  of  the  under  side  entirely 
obliterated.  The  only  other  instance  known  to  me  of  such  a  structure 
is  in  Apotomus,  which  Schaum  says  is  distinguished  from  all  other 
Carabidae  in  this  manner. 

Tribe  XXX.— Dryptini. 

Antennae  setaceous,  free  at  base,  three  basal  joints  somewhat  less  pubescent, 
the  first  usually  elongate  and  thicker  than  the  following.  Head  constricted  at 
a  variable  distance  behind  the  eyes  to  a  neck  which  sometimes  expands  semi- 
globularly  at  its  insertion  in  the  thorax,  front  narrowed  before  the  eyes,  two 
supra-orbital  setse,  clypeus  moderately  prolonged  and  with  a  variable  number 
of  setigerous  punctures,  sometimes  (Drypta)  without  any.  Eyes  oval  moderately 
prominent,  usually  not  very  close  to  the  mouth  beneath.  Labrum  transverse, 
moderately  prominent,  truncate  or  feebly  emarginate,  sexsetose  in  front,  the  two 
lateral  setse  in  Drypta  stouter,  longer  and  nearly  vertical.  Mandibles  slightly 
prominent,  feebly  arcuate,  acute  at  tip.  Maxillae  hooked  at  tip,  ciliate  or  spinous 
within,  outer  lobe  usually  slender,  biarticulate,  with  equal  lobes,  palpi  long,  more 
or  less  hirsute,  the  terminal  joint  more  or  less  triangular.  Mentum  variable  in 
form,  deeply  emarginate  with  or  without  tooth,  ligula  and  paraglossae  variable  in 
form,  the  palpi  moderately  long,  the  terminal  joint  shorter  than  the  preceding, 
more  or  less  triangular  in  form,  the  penultimate  longer  and  plurisetose  in  front. 
Thorax  variable  in  form,  often  moderately  long,  the  lateral  margin  acute,  (except 
in  Drypta)  the  lateral  setae  often  indistinct,  that  of  the  posterior  angle  usually 
entirely  absent.  Scutellum  distinct.  Elytra  not  margined  at  base,  lateral  margin 
acute,  entire,  apex  truncate,  dorsal  punctures  absent  except  in  Stenochila.  Pro- 
sternum  not  prolonged.  Mesosternal  epimera  very  narrow.  Metasternal  epimera 
distinct,  posterior  coxae  contiguous.  Legs  moderately  long,  the  femora  often  slightly 
clavate,  the  middle  and  posterior  tibiae  ciliate  or  slightly  spinous  externally,  the 
anterior  slender,  deeply  emarginate  within,  the  tibial  spurs  moderate  in  length, 
rarely  ( Galerita)  long.     Tarsi  variable  in  form,  the  claws  simple  or  pectinate. 

The  males  have  the  anterior  tarsi  dilated,  sometimes  very  slightly  and  densely 
juibescent  beneath. 

The  tribe  as  here  constituted  is  the  equivalent  of  Lacordaire's  Galeri- 
tides,  for  which  later  authors  have  adopted  the  name  which  I  retain. 

I  have  already  given  in  the  Ctenodactylini  the  reasons  for  the  change 
of  places  of  Stenochila  and  Caloplipemt.  Poli/stichua  is  removed  to 
Ilelluonini  for  reasons  which  will  hereafter  be  given.  The  essential 
character  separating  the  Dryptini  from  all  other  Truncatipennes  is  found 
in  the  structure  of  the  labial  palpi.  The  form  of  the  basal  joint  of  the 
antennae  usually  relied  on  is  by  no  means  a  good  character  as  several  of 
the  preceding  tribes  have  the  first  joint  even  longer  than  some  of  those 
of  the  present.     Where  the  scape  attains  its  typical  length  it  is  usually 


AMERICAN   COLEOPTERA.  149 

more  or  less  curved  near  the  base  as  in  Agra.  It  is  difficult  in  many  of 
the  genera  to  say  how  many  joints  are  truly  pubescent  as  the  hairs  extend 
nearly  to  the  base  of  the  first  joint. 

The  head  assumes  three  forms,  the  first  is  that  typified  by  Galerita  in 
which  the  head  is  elongate-oval,  considerably  prolonged  behind  the  eyes 
then  constricted  to  a  very  narrow  neck  which  dilates  to  a  semiglobular 
condyle,  the  second  is  the  Zuphium  type  where  there  is  a  moderate  pro- 
longation behind  the  eye  and  then  very  suddenly  constricted  to  a  narrow 
neck  which  is  cylindrical,  while  in  Drypta  the  constriction  is  close  to  the 
eyes,  not  abrupt  and  the  neck  rather  stout  and  cylindrical.  The  latter 
genus  is  further  remarkable  in  having  the  setae  of  the  clypeus  entirely 
wanting,  their  function  being  replaced  by  those  of  outer  side  of  the 
labrum  which  ac([uire  an  unuBual  development,  a  similar  occurrence  has 
been  observed  in  Pelecium. 

This  tribe  through  Galerita  and  Stenochila  shows  a  relationship  well 
marked  with  the  Odacanthini,  and  by  Thalpius  to  the  Helluonini  through 
Folyatichus  which  must  be  placed  in  the  latter  tribe. 

Our  genera  are  not  numerous  and  may  be  known  by  the  characters 
of  the  following  table  : 

Neck  very  narrow. 

Head  prolonged  behind  the  eyes,  neck  inserted  in  thorax  by  a  semiglobular 

condyle.     Clypeus  with  two  setigerous  punctures  each  side Galerita. 

Head  triangular  scarcely  prolonged  behind  the  eyes,  very  suddenly  constricted 
to  a  narrow  cylindrical  neck.     Clypeus  with  but  one  setigerous  puncture  on 

each  side  with  a  long  seta Zii|> Ilium. 

Neck  stout,  head  very  little  constricted. 

Thorax  truncate  at  base,  antennae  with  third  joint  shorter  than  the  fourth. 

Diapliurus. 
Thorax  subpedunculate  at  base,  antennse  with  joints  2—4  nearly  equal. 

Thalpius. 

The  above  genera  are  represented  on  both  sides  of  the  continent. 

Tribe  XXXI.— Mormolycini. 

Antennse  slender,  nearly  as  long  as  the  body,  the  base  exposed,  four  basal  joints 
glabrous,  the  following  densely  punctured  and  very  finely  pubescent,  first  joint 
elongate  pyriform,  second  short,  third  as  long  as  the  head,  fourth  a  little  shorter, 
5—11  much  shorter,  subequal.  Head  very  long  behind  the  eyes,  forming  a  flat- 
tened neck  which  is  moderately  constricted  at  base  and  expanded  semiglobularly 
at  its  insertion  in  the  thorax,  front  with  two  small  supra-orbital  setae.  Clypeus 
moderately  prolonged,  feebly  emarginate,  a  setigerous  puncture  each  side.  Eyes 
round,  moderately  prominent,  distant  beneath  from  the  buccal  fissure.  Labrum 
nearly  square,  feebly  emarginate  and  sexsetose  in  front.  Mandibles  stout,  arcuate, 
tip  acute,  a  small  tooth  at  middle  on  the  right  side,  near  apex  on  the  left,  outer 
side  concave  at  base,  without  setigerous  puncture,  upper  side  with  a  short  but  deep 
cicatrix-like  fissure  at  the  end  of  the  carina.  Maxillae  moderately  short,  hooked 
at  tip,  inner  edge  densely  ciliate,  outer  lobe  slender,  biarticulate,  the  palpi  stout,

the  terminal  joint  subeylindrical  obtuse  at  tip.  Mentum  deeply  emarginate  and 
with  a  slender  acute  tooth.  Ligula  slender  acute  and  bisetose  at  tip,  the  paraglossse 
broad,  membranous,  adhering  to  the  ligula  to  the  tip  and  prolonged  beyond  it  but 
not  becoming  united,  the  palpi  stout,  terminal  joint  suboylifidrical,  obtuse  at  tip, 
with  short  ciliae  on  its  inner  side,  penultimate  joint  bisetose  in  front.  Thorax 
elongate  the  margin  with  a  coarsely  dentate  expansion  and  without  setigerous 
punctures.  Seutellum  distinct.  Elytra  (less  the  expansion)  oblong-oval,  truncate 
at  tip,  the  sutural  angle  acute,  base  not  margined,  very  narrowly  embracing  the 
body,  the  margin  acute  and  expanded  in  a  foliaceous  plate  which  is  prolonged 
beyond  the  apices  of  the  elytra,  surface  striate,  the  third  interval  with  three 
dorsal  punctures  each  situated  in  a  small  tubercle.  Prosternum  not  prolonged, 
the  thoracic  sutures  obsolete.  Mesosternum  narrowly  separating  the  coxse,  the 
epimera  broad  and  attaining  the  coxse.  Metasternal  episterna  also  attaining  the 
middle  coxse,  the  epimera  distinct.  Posterior  coxse  contiguous.  Legs  long  and 
slender,  middle  tibise  ciliate  near  the  tip,  posterior  tibiae  not  ciliate,  anterior  tibiae 
emarginate  within,  the  spurs  on  all  the  tibise  ^mall.  Tarsi  similar  in  the  sexes, 
slender,  the  first  joint  as  long  as  the  next  three  and  with  short  hairs  beneath,  the 
other  joints  not  ciliate.     Claws  simple. 

This  tribe  is  represented  by  the  single  genus  Mormolyce  containing 
three  species  which  occur  in  Java  and  adjacent  regions.  It  is  especially 
remarkable  in  being  the  only  exception,  as  far  as  I  know,  to  the  value  of 
the  mesosternal  epimeron  in  determining  the  position  of  a  genus  in  the 
Carabide  series.  In  the  preceding  pages  I  have  attempted  to  demonstrate 
that  Siagona  and  the  Ozjenini  have  the  mesosternum  formed  in  the 
manner  normal  to  the  present  sub-family.  It  will  also  be  observed  by 
the  figure  of  the  under  side  of  Mormoltjce  (PI.  Ill,  fig.  3),  that  the 
metasternal  episterna  also  reach  the  middle  coxa3,  a  character  entirely 
without  parallel  in  all  the  Carabidae  although  quite  common  in  Dytiscidae 
and  present  in  Amphizoa. 

The  position  of  the  genus  after  disregarding  the  anomalous  sternal 
structure  is  still  open  to  discussion.  The  association  of  it  with  the 
Feronides  (Pterostichiui)  by  the  older  authors  is  now  generally  abandoned 
and  all  seem  to  agree  that  it  is  a  true  Truncatipenne.  Chaudoir  (Bull. 
Mosc.  1848,  i,  p.  123),  indicated  for  it  a  position  near  Thyreopteriis  an 
opinion  since  repeated  (Ann.  Belg.  xii,  1869,  p.  133),  but  with  Avhich 
I  can  not  agree.  Even  the  most  enthusiastic  advocates  of  such  an  idea 
must  admit  that  it  is  about  as  unlike  the  other  genera  of  the  Thyre- 
opterides  of  Chaudoir  as  it  is  unlike  an  ordinary  Lebia. 

Those  whose  range  of  study  extends  over  the  entire  Coleoptera  have 
observed  that  genera  occur  in  very  many  families  in  which  the  species, 
by  the  enormous  development  of  some  members  of  the  external  portion 
of  the  body,  assume  a  form  or  appearance  entirely  concealing  the  true 
relationship.  Instances  of  mimicry  are  numerous  but  these  are  foreign 
to  the  idea  at  present  intended.  ^ 


AMERICAN    COLEOPTERA.  .,  151 

Mormolyce  is  in  particular  one  of  those  genera  with  unusual  develop- 
ments. These  are  the  margining  of  the  thorax  and  the  leaf-like  expansion 
of  the  eljtral  margin.  If  we  dismiss  for  a  moment  from  our  consideration 
these  appendages  and  allow  Mormolyce  to  stand  as  if  deprived  of  them 
it  becomes  reduced  to  an  insect  not  very  diiFerent  from  an  Odacanthide 
or  a  Ctenodactylide. 

The  elongate  head,  with  the  extremity  of  the  neck  dilated  in  a  semi- 
globular  manner,  the  narrow  thorax,  the  elytra  not  margined  at  base, 
the  dorsal  punctures  all  on  the  third  interval,  are  characters  which 
cannot  be  neglected. 

The  ligula  and  paraglossae  of  Mormolyce  are  said  to  be  as  in  the 
Thyreopterides  but  from  the  descriptions  these  organs  vary  in  that 
group,  and  in  the  present  genus  I  do  not  find  as  much  resemblance 
to  Eurydera  as  to  Coptodera  serata  (84). 

I  would  suggest  that  Mormolyce  be  constituted  a  distinct  tribe  to  be 
placed  in  the  vicinity  of  the  Odacanthini  and  Ctenodactylini. 

Tribe  XXXII.— Agrini. 
Antennae  slender,  moderately  long,  arising  under  a  slight  frontal  plate,  three 
basal  joints  glabrous,  first  joint  moderate  in  length,  slightly  arcuate  near  the  base, 
second  short,  third  longer  than  the  following  which  are  subequal  in  length.  Head 
elongate,  prolonged  behind  the  eyes  and  suddenly  constricted  to  a  neck  which 
forms  a  seraiglobular  condyle,  front  with  two  supra-orbital  setse.  Clypeus  moder- 
ately prolonged,  a  setigerous  puncture  each  side.  Eyes  moderately  prominent, 
close  to  the  mouth  beneath.  Labrum  moderately  prominent,  nearly  square  or 
slightlj'  transverse,  sexsetose  in  front.  Mandibles  slightly  prominent,  feebly 
arcuate,  acute  at  tip  without  setigerous  puncture.  Maxillse  hooked  at  tip,  with 
very  short  cilise  within,  the  outer  lobe  rather  stout,  biarticulate,  the  terminal  joint 
shorter,  palpi  stout  not  long,  the  terminal  joint  subcylindrical,  longer  than  the 
preceding  and  obtuse  at  tip.  Mentum  moderately  emarginate  with  an  obtuse 
tooth  sometimes  nearly  as  long  as  the  lateral  lobes.  Ligula  coriaceous,  more  or 
less  rhomboidal,  moderately  prominent,  quadrisetose,  two  setae  at  the  tip  and  one 
on  each  side  posteriorly,  paraglossee  membranous,  adherent  to  the  ligula  and  not 
longer,  palpi  longer  than  the  nftixillaries,  the  terminal  joint  broadly  securiform, 
the  penultimate  bisetose  in  front.  Thorax  elongate  conical,  the  lateral  margin 
almost  obliterated,  the  lateral  and  angular  setigerous  punctures  indistinct.  Scutel- 
lum  distinct,  feebly  prolonged  between  the  elytra.  Elytra  prolonged  at  base  and 
not  margined  there,  sides  narrowly  inflexed,  lateral  margin  entire,  without  internal 
plica,  the  apex  truncaite  and  often  spinous  or  dentate,  surface  variably  sculptured 
but  when  striate  the  dorsal  punctures  are  numerous  and  very  evident  on  the 
striae  2—4 — 6,  the  ninth  stria  close  to  the  margin.  Prosternum  not  prolonged. 
Mesosternum  oblique,  the  epimera  very  narrow.  Metasternal  epimera  distinct, 
posterior  coxse  contiguous.  Legs  moderate  in  length,  femora,  especially  the  ante- 
rior, somewhat  clavate,  tibise  slightly  ciliate  externally,  the  terminal  spurs  small, 
anterior  tibiae  deeply  emargiiiate  within.  Tarsi  moderate  in  length,  flattened  on 
all  the  feet,  ciliate  above,  densely  pubescent  beneath  and  ciliate  at  the  sides,  fourth 
joint  deeply  bilobed.     Claws  stout,  pectinate  in  their  entire  length. 


152  ^  GEO.    H.    HORN,    M.  D. 

The  anterior  tarsi  of  the  male  are  more  dilated  than  in  the  female.  The  sexual 
characters  are  otherwise  variable  and  are  found  in  the  form  of  the  middle  and 
posterior  tibiae  and  the  sculpture  and  pubescence  of  the  abdomen. 

In  comparing  the  species  of  this  tribe  with  those  of  the  Odacanthini 
and  CtenodactyUni  it  will  be  seen  that  there  is  a  close  relationship  which 
can  not  be  neglected  for  the  structure  of  the  ligula  alone.  By  retaining 
Agra  in  any  part  of  the  true  Lebiide  series  we  introduce  confusion  as 
great  as  with  Mormolyce.  In  many  parts  of  the  Carabide  series  the 
ligula  has  been  entirely  neglected  where  its  consideration  would  cause  an 
obvious  violation  of  natural  affinities.  Conspicuous  among  these  cases  of 
neglect  we  find  the  Cxraphipterini  and  Athiini. 

It  may  be  well  to  call  attention  to  the  fact  that  in  all  the  tribes 
with  long  head  and  thorax  the  tibial  spurs  are  exceptionally  small,  and 
Lacordaire  says  of  Agra  "  sans  epines  terminales." 

The  species  of  this  tribe  belong  to  two  genera,  Agra  and  Agridia  and 
all  with  one  exception  occur  in  intertropical  America. 

Tribe  XXXIII.— Egini. 

Antennae  moderate  in  length,  slightly  thicker  externally,  arising  under  a  feeble 
frontal  ridge,  the  four  basal  joints  glabrous,  that  is  they  are  somewhat  hairy  but 
not  densely  punctured  and  finely  pubescent  as  the  following  joints,  the  basal  joint 
moderately  stout  but  not  equal  in  length  to  the  two  following  joints  together. 
Head  oval  rather  strongly  constricted  at  a  distance  behind  the  eyes  to  a  neck,  with 
two  supra-orbital  setae.  Eyes  oval  in  the  axis  of  the  head,  moderately  prominent 
but  distant  beneath  from  the  mouth.  Clypeus  feebly  prolonged,  a  setigerous 
puncture  each  side.  Labrum  feebly  prominent,  slightly  emarginate,  sexsetose. 
Mandibles  acute  at  tip,  without  setigerous  puncture  externally.  Maxillse  slender, 
slightly  hooked  at  tip,  spinulose  and  ciliate  internally,  outer  lobe  slender,  biarticu- 
late,  the  terminal  joint  shorter,  the  palpi  moderate  in  length,  the  terminal  joint 
obovoid,  suddenly  narrowed  and  prolonged  at  tip,  surface  pubescent.  Mentum 
deeply  emarginate  and  with  a  short  obtuse  tooth;  ligula  not  prominent,  emar- 
ginate and  bisetose  at  apex,  the  tip  free  for  a  short  distance,  paraglossse  slightly 
longer  than  it,  palpi  moderate  the  terminal  joint  like  that  of  the  maxilla,  the 
penultimate  bisetose  in  front.  Thorax  ovate,  somewhat  constricted  at  base,  margin 
almost  entirely  obliterated,  sides  with  two  setigerous  punctures  placed  almost  as 
in  the  Clivince.  Body  distinctly  pedunculate,  scutellum  not  visible  between  the 
elytra.  Elytra  not  margined  at  base  and  without  scutellar  stria,  lateral  margin 
obsolete,  sides  narrowly  inflexed,  apex  subtruncate,  disc  striate  at  base,  dorsal 
punctures  three  but  indistinct.  Prosternum  not  prolonged.  Mesosternum  oblique, 
the  epimera  very  narrow.  Metasternal  epimera  distinct,  posterior  coxae  separated. 
Legs  slender,  tibiae  ciliate  externally,  the  anterior  deeply  emarginate  within. 
Tarsi  slender  and  long,  fourth  joint  entire.     Claws  simple. 

The  anterior  tarsi  of  the  male  are  merely  a  little  stouter  than  those  of  the 
female  and  somewhat  more  ciliate. 

I  know  of  but  one  genus  which  enters  this  tribe,  Ega.  In  the  books 
it  forms  a  part  of  Lacordaire's  tribe  Anchonoderides  and  with  Schaum 
and  LeConte  of  the  more  comprehensive  tribe  Odacanthini. 


AMERICAN    COLEOPTERA.  •  153 

The  many  peculiar  characters  which  Ega  possesses  seem  to  me  sufficient 
to  place  it  as  a  distinct  tribe.  In  the  present  series  the  pedunculate 
body  is  known  to  me  as  occurring  only  in  the  Anthiini  and  it  is  here  too 
that  we  have  the  posterior  coxae  separated  and  the  eyes  oval  in  the  axis 
of  the  head.  It  is  by  no  means  easy  to  determine  the  true  thoracic 
setigerous  punctures  as  there  are  many  short  erect  hairs,  the  true  tactile 
setas  will  be  found  remaining  when  the  others  are  lost.  The  obliteration 
of  the  side  margin  of  the  thorax  is  nearly  as  complete  as  in  Apotnmus 
while  the  absence  of  the  lateral  margin  of  the  elytra  is  an  important 
character  which  appears  to  have  been  lost  sight  of. 

The  separation  of  the  posterior  coxas  seems  to  me  evidence  of  a 
degraded  or  undeveloped  type. 

The  relationship  of  the  present  tribe  is  undoubtedly  with  certain 
members  of  the  Anchonoderini  while  the  relationship  with  the  Anthiini 
indicated  above  may  be  merely  the  possession  of  several  characters  in 
common ;  there  may,  however,  be  genera  unknown  to  me  wliich  show 
a  true  affinity  between  the  two  tribes. 

Ega  is  represented  in  our  fauna  by  two  species,  Sallei  from  the  Gulf 
States,  Isetula  from  California.  In  the  first  the  elytral  grooves  or  striae 
do  not  extend  behind  the  middle  and  the  three  dorsal  punctures  are 
faintly  indicated ;  in  the  second  the  striae  extend  at  least  two-thirds  of 
the  elytra  and  I  have  been  unable  to  detect  any  dorsal  punctures. 

Tribe  XXXIV.-Lebiini. 
Antennse  slender,  rarelj'  slightly  thickened,  arising  under  a  slight  frontal  ridge, 
the  condyle  usually  exjiosed,  the  three  basal  joints  generally  glabrous,  sometimes 
however,  but  two  or  four.  Head  oval,  constricted  to  a  neck  or  not,  with  two 
supra-orbital  setse,  front  either  parallel  or  with  convergent  sides,  clypeus  with  a 
setigerous  puncture  each  side.  Eyes  round  or  oval,  moderately  prominent  very 
narrowly  separated  from  the  mouth  beneath.  Labrum  usually  broader  than  long, 
sometimes  prolonged  covering  the  mandibles,  either  truncate  or  emarginate  and 
sexsetose  in  front.  Maxillfe  slender  hooked  at  tip,  rather  obtusely  in  Teiragono- 
derus,  ciliate  or  spinulose  within  rarely  toothed  behind  the  tip  {Euccerus  and 
Teiragonoderus)  the  apex  ciliate  in  many  genera,  outer  lobe  biarticulate  but  other- 
wise variable,  the  palpi  variable  in  form  from  slender  to  securiform.  Mentum 
more  or  less  deeply  emarginate,  the  epilobes  always  distinct,  the  bottom  of  the 
emargination  either  without  tooth  or  with  a  tooth  of  variable  form ;  ligula  and 
paraglossse  very  variable,  the  palpi  also  variable  the  terminal  joint  equal  to  the 
preceding  or  longer,  the  latter  bisetose  in  front  (except  in  some  Cymindis).  Thorax 
variable  in  form,  sides  distinctly  margined  and  with  a  seta  at  the  side  and  at  the 
basal  angle.  Elytra  truncate  at  tip  in  a  variable  manner,  the  margin  acute,  entire 
and  narrowly  inflexed,  without  internal  plica,  the  base  margined.  Prosternum 
usually  obtuse  at  tip,  rarely  acute  or  prolonged  {CydosomuH).  Mesosternal  epi- 
mera  narrow,  sometimes  almost  entirely  concealed  by  the  episterna.  Metasternal 
epimera  distinct,  the  posterior  coxse  contiguous.     Legs  usually  slender,  not  very

long,  tiljise  slender  the  terminal  spurs  moderate  or  short,  rarely  long  {Tetragono- 
derus,  Nemotarsus),  simple,  rarely  finely  serrulate  along  their  margins  (Tetragono- 
derus,  etc.).  Tarsi  variable  in  form,  the  fourth  joint  narrow,  emarginate,  or  deeply 
hilobed,  the  claws  usually  pectinate  or  serrulate,  sometimes  however  simple. 

The  sexual  characters  are  variable.  The  anterior  tarsi  are  often  very  nearly 
equal  in  the  sexes,  sometimes  with  three  or  four  joints  slightly  dilated  in  the  male, 
rarely  the  middle  tarsi  are  dilated  (Pinacodera).  The  anal  segment  has  usually 
more  setse  in  the  female  than  in  the  male. 

The  tribe  as  here  intended  is  the  equivalent  of  Lacordaire's  Lebiides 
and  Pericalides  omitting  especially  Agra  and  Mormo/j/ce. 

After  having  given  the  tribe  a  careful  -study,  having  purposely  left  it 
for  the  final  work  in  the  present  paper,  I  have  found  myself  with  the 
same  result  as  that  arrived  at  by  Lacordaire  and  LeConte,  namely,  that 
it  is  not  possible  to  divide  the  tribe  in  any  satisfiictory  manner.  I  have 
dissected  the  mouth  parts  of  all  our  own  genera  which  are  figured,  with 
many  foreign  to  our  fauna  and  the  only  conclusion  I  can  arrive  at,  is, 
that  the  ligula  and  paraglossae  have  very  little  value  in  defining  groups 
of  genera.  I  can  cite  the  two  figures  of  the  ligula  of  Valllda  (93,  94), 
in  these  the  paraglossae  are  not  united  by  a  membrane  which  crosses  the 
front  of  the  ligula,  nor  do  we  find  it  so  in  Dromius.  In  both  of  the 
groups  which  Chaudoir  bases  on  these  two  genera  as  types  the  paraglossae 
should  be  united  by  a  membrane  crossing  the  front  of  the  ligula. 

The  Lebiides  of  Baron  Chaudoir  are  separated  more  especially  by  the 
paraglossae  pilose  at  tip  and  the  intermediate  tibiie  of  the  male  notched 
within  near  the  tip.  The  other  characters  given,  occur,  as  every  one  will 
see,  in  all  parts  of  the  Lebiide  series.  Other  genera  as  in  Dromius  (86) 
and  Pinacodera  (97)  have  the  paraglossae  ciliate  at  tip,  while  the  male 
of  Coptodera  a&rata  has  the  middle  tibiae  incised  as  in  Lehia.  The 
further  division  of  the  Lebiides  into  genera  with  and  without  epilobes 
to  the  mentum  is  also  misleading  and  I  am  quite  prepared  to  state  that 
there  is  no  Carabide  without  epilobes. 

By  these  remarks  I  do  not  desire  to  discredit  the  work  done  by 
Baron  Chaudoir*  who  is  acknowledged  to  be  the  ablest  Carabologist  of 
the  present  time.     The  tribes  and  groups  he  indicates  are  composed  of 

*  This  and  the  preceding-pai'agrapjis  may  read  strangely  now  that  Chaudoir  is 
no  more.  They  were  written  before  his  death  and  intended  as  full}'  for  his  perusal 
as  for  any  one  else.  For  many  years  Chaudoir  has  contributed  valuable  papers  to 
our  knowledge  of  the  Truncatipenne  series,  and  as  it  has  been  found  impossible  to 
present  my  own  views  without  directly  quoting  him,  I  do  not  think  that  any 
change  of  language,  apparently  less  critical,  would  be  of  benefit  in  any  respect. 
I  can  only  add  that  our  relations,  even  with  differences  of  opinion,  have  always 
been  of  the  most  cordial  nature,  and  were  he  living  the  remarks  here  presented 
would  be  accepted  in  the  spirit  in  which  they  are  intended. 


AMERICAN    COLEOPTERA.  155 

genera  very  closely  and  naturally  allied,  but  the  definition  of  these  groups 
is  very  artificial  and  we  find  already  a  great  number  of  odd  genera  thrown 
aside  which  will  not  fit  in  any  tribe  he  has  proposed  and  which  must  of 
necessity  form  groups  by  themselves.  Such  a  minute  subdivision  is  con- 
fusing but  would  be  excusable  and  even  acceptable  if  the  characters  on 
which  it  is  founded  were  even  moderately  constant,  but  with  the  few 
genera  which  occur  in  our  fauna  I  can  say  that  no  characters  exist  in  the 
ligula  which  can  be  used  to  divide  the  tribe  into  groups. 

In  the  accompanying  table  the  characters  seem  hardly  to  warrant  any 
further  explanation.  Attention  might  be  directed  to  the  very  long  tibial 
spurs  of  Tetragonodeinis  and  Nemotarsus,  in  the  former  genus  their  edges 
are  finely  serrulate  a  remarkable  character  in  the  present  family  and  one 
which  is  by  no  means  common  in  Coleoptera  generally. 

In  Fentagonica  (Rhombodera)  which  in  its  form  occupies  an  inter- 
mediate position  between  Lehia  (Aphelogenia)  and  Eucxrus  the  mandi- 
bles are  without  scrobes,  that  is  they  are  deprived  of  that  triangular 
groove  on  the  outer  side  so  commonly  present  in  the  Carabidae.  The 
mandibles  here  recall  those  of  Loricera  or  Leistus  although  the  lower 
edge  is  less  expanded  than  in  these  two  genera. 

To  the  present  tribe  and  in  close  association  with  Tetragonoderia;,  Chau- 
doir  has  added  C'^closomus  a  curious  genus  of  a  form  and  aspect  closely 
resembling  Omophron,  it  is  however  correctly  placed  by  that  author. 

Eucserus  which  will  be  found  in  one  of  the  extremes  of  the  following 
table  is  one  of  those  unfortunate  genera  which  has  never  been  allowed  to 
remain-  for  any  length  of  time  in  any  one  position.  At  its  beginning  it 
was  placed  «ear  the  Harpali,  thence  (Class.  Col.  N.  A.  p.  22),  it  was 
removed  and  made  part  of  a  rather  composite  tribe  and  placed  near  the 
Lachnophori.  Chaudoir  accepts  this  view.  While  it  is  doubtless  an 
o.sculaut  form  it  seems  to  me  more  nearly  allied  to  the  present  series 
than  to  Lachnophorua. 

The  maxillae  present  a  few  variations  from  the  usual  fixed  type  and 
attention  is  directed  to  the  fignires  of  Tetragonoderus,  Eucserus  and 
Pinacodera. 

The  antennae  are  very  constant  in  their  pubescence.  In  the  vast 
majority  of  species  the  three  basal  joints  and  the  adjacent  half  of  the 
fourth  are  glabrous,  but  in  Phloeoxena  four  joints  are  smooth  while  in 
Eucserus  the  third  is  pubescent  and  the  second  scarcely  less  so. 

The  genera  below  are  those  known  at  present  in  our  fauna.  To  have 
introduced  those  exotic  genera  known  to  me  would  not  have  been  a 
difficult  task,  but  it  seemed  to  me  to  be  unnecessary  as  very  nearly  if 


15()  GEO.    H.    HORN,    M.  D. 

not  quite  all  the  subdivisions  suggested  by  Chaudoir  are  represented  by 
genera  around  which  the  exotics  may  be  grouped.

Ungues  simple,  fourth  tarsal  joint  not  dilated Peiitagonica.

Tetragonoderus  Dej. — This  genus  is  made  the  type  of  a  tribe  by 
Baron  Chaudoir  (Bull.  Mosc.  1876),  in  which  four  other  genera  are 
included,  the  essential  characters  being  the  form  of  the  maxillae  (80) 
and  the  structure  of  the  tibial  spurs.  The  extremity  of  the  inner  lobe 
of  the  maxilla  is  spoken  of  by  Chaudoir  rather  as  an  appendix,  but  it 
seems  to  be  rather  the  true  termination,  the  hook  behind  it  corresponding 
with  the  tooth  which  will  be  seen  in  the  figure  of  Eucserus  (100). 
If  we  consider  the  tooth  as  the  tip  of  the  maxilla  we  have  the  anomaly 
presented  of  the  outer  or  palpar  lobe  longer  than  the  inner,  a  character 
not  otherwise  observed  in  the  Carabidse. 

Nemotarsus  Lee. — This  name  has  through  the  suggestion  of  some 
extreme  purists  been  lengthened  to  Nematotarsus  without  however  adding 
anything  to  a  knowledge  of  the  genus  itself.  This  genus  is  placed  by 
Chaudoir  in  association  with  Tetragonoderus  but  not  in  the  same  tribe. 
It  is  one  of  those  genera  which  will  fit  in  several  tribes  on  a  ligular 
basis  but  will  be  excluded  by  characters  which  must  be  allowed  to  have 
more  weight. 

Lebia  Latr. — This  genuS'  has  also  been  made  the  type  of  a  tribe  by 
Chaudoir,  to  which  he  assigns  characters  by  no  means  peculiar  to  the 
genera  included.  Attention  has  already  been  partially  directed  to  these 
characters.  In  consequence  of  the  existence  of  epilobes  in  the  mentum 
of  all  our  species,  it  has.  been  found  impossible  to  retain  the  divisions 
suggested  by  Chaudoir.  In  the  figures  of  the  mentum  Aphelogenia  (83) 
will  be  found  to  have  epilobes  but  less  developed  than  in  Loxopeza  (82). 
The  species  occurring  in  our  fauna  are  all  referred  to  Lebia  while  the 
divisions  suggested  by  Chaudoir  are  rather  groups  of  species  than  genera. 

CoPTODERA  Dej. — This  is  also  the  type  of  a  tribe  in  the  hands  of 
Baron  Chaudoir,  and  that  future  students  of  our  fauna  may  have  the 
special  characters  of  the  tribe  at  hand  I  reproduce  them.  (Ann.  Belg. 
xii,  1869)  :  "  Ligula  cornea,  apice  baud  libera  plerumque  bisetosa,  inter- 
dum  praeterea  pluripilosa ;  paraglossse,  menibranaceae,  apice  pilosulae,  aut 
conniventes  (ut  in  Coptodera)  aut  ligulam  vix  superantes.  Csetera  ut 
in  Thyreopteridisy 

In  what  respect  the  Coptoderides  differ  from  the  Thyreopterides 
I  have  not  been  able  to  realize  even  with  patient  study.

158  GEO.    H.    HORN,    M.  D. 

Phlceoxena  Chaud. — This  genus  is  due  to  Chaudoir  (Ann.  Belg. 
xii,  1869,  p.  145),  and  is  founded  on  species  mostly  Mexican  with 
which  our  Coptodera  signata  Dej.,  is  associated.  In  his  generic  cha- 
racters Chaudoir  says :  "  Mentum  *  *  *  medio  sinu  dente  majusculo, 
trigono,  apice  rotundato,"  but  I  do  not  observe  any  tooth  whatever  in 
our  species. 

This  genus  is  part  of  the  tribe  Thyreopterides. 

Dromius  Bon.,  Apristus  Chd.,  Blechrus  Motsch.,  Metablettjs 
Schmidt,  and  Axinopalpus  Lee,  have  not,  as  far  as  I  am  aware,  been 
reviewed  by  Chaudoir,  and  are  probably  a  part  'of  his  intended  tribe 
Dromiides  which  is  merely  casually  mentioned  in  his  preliminary  remarks 
on  the  Callidides,  (Ann.  Belg.  xv,  1872).  These  genera  may  therefore 
be  passed  without  further  remark  than — that  the  ligula  is  not  always  bor- 
dered in  front  by  the  extension  of  the  paraglossae,  not  even  in  Dromius. 
Certain  European  authors,  among  them  Baron  Chaudoir,  have  rejected 
the  name  Axinopalpus  for  Variopalpus  having  been  misled,  evidently, 
by  the  date  given  in  the  Munich  Catalogue.  The  former  genus  was 
published  in  1846,  the  latter  in  1848. 

Tecnophilus  Chaud.,  Bull.  Mosc.  1877,  i,  p.  240. — This  genus  is 
suggested  for  those  species  in  our  fauna  formerly  placed  in  Philotecnus 
Mann.,  with  which  Chaudoir  says  they  have  nothing  to  do. 

"  Vu  la  configuration  de  sa  languette  que  ses  paraglosses  ne  bordent 
pas  anterieurement,  ce  genre  ne  fait  pas  partie  du  groupe  des  Callidides, 
mais  de  celui  des  31imodromiides  dont  je  n'ai  pas  encore  expose  les 
caracteres  qui  demandent  a  etre  mieux  etudies." 

The  ligula  and  paraglossfe  reproduce  exactly  those  of  a  species  of 
Gallida,  as  yet  undescribed,  which  resembles  umaragdina  very  closely 
and  differs  from  it  in  nearly  the  same  manner  that  decora  and  punctata 
do  from  each  other. 

Callida  Dej.,  EuPROCTUS  Sol.,  Plochionus  Dej.,  form  part  of  the 
Callidides  of  Chaudoir,  (Ann.  Belg.  xv,  1872),  which  has  already  been 
sufficiently  remarked  upon.  Several  of  our  species  of  Callida  have 
been  separated  to  form  the  genus  Sponyoloba  Chd.,  based  on  sexual 
peculiarities  of  the  male  which  seem  to  me  to  have  had  too  great 
value  assigned  them.  Euproctus  is  represented  in  our  fauna  by  one 
species  described  as  Onota  trivittata  Lee.     (PI.  IV,  fig.  3). 

Philophuga  Motsch.,  contains  those  species  formerly  placed  in 
Glycia.  They  are  reviewed  by  Chaudoir,  (Bull.  Mosc.  1877,  i,  p.  243), 
who  leaves  us  in  doubt  whether  the  genus  is  part  of  his  Callidides  or 
not.     They  are  not  included  in  that  essay. 


AMERICAN    COLEOPTERA.  159 

Cymindis  Latr.,  is  the  subject  of  an  essay  by  Chaudoir,  (Berl. 
Zeitschr.  1873),  and  with  three  other  genera  constitutes  the  tribe  Cymin- 
dides,  but  I  find  that  there  are  no  special  characters  assigned  to  it. 

PiNACODERA  Schaum,  and  APENES  Lee,  are  treated  by  Chaudoir  in 
a  paper  entitled,  "Genres  aberrants  du  groupe  des  Cymindides,"  (Bull. 
Mosc.  1875),  and  as  there  are  no  characters  assigned  to  the  group  it  is  im- 
possible to  ascertain  in  what  respect  these  genera  are  especially  aberrant. 

Euc^RUS  Lee,  has  already  been  referred  to. 

PentaCtOXICA  Schmidt-Goebel,  which  has  for  its  synonyms  Didetus 
Lee,  and  Rhomhndera  Reiche,  is  the  subject  of  a  short  essay  by  Chau- 
doir, (Bull.  Mosc.  1877,  i,  p.  212),  who  says  that  it  is  "one  of  those 
aberrant  genera  which  can  not  be  made  to  enter  any  of  the  groups 
established  at  the  present  time.  I  believe  that  jMr.  Bates  is  correct  in 
placing  it  in  a  special  group  under  the  name  Pentagonicinse,"  (Trans. 
Ent.  Soc.  London,  1873,  p.  320).  This  is  certainly  an  easy  settlement 
of  the  difficulty,  more  particularly  as  no  characters  are  assigned  to 
the  group. 

Corsyra. — This  genus  does  not  occur  in  our  fauna.  I  merely 
introduce  it  here  to  express  a  view  that  it  has  nothing  to  do  with 
Graphipterus  as  intimated  by  Chaudoir,  (Bull.  Mosc.  187G).  The  well 
marked  supra-orbital  and  thoracic  setae,  the  structure  of  the  labial  palpi 
and  tibial  spurs  all  forbid  its  position  there. 

Onota  Chd.,  is  represented  by  one  species  found  in  Florida: 

O.  Floridana  n.  sp.— Rufo-testaeeous,  elytra  brilliant  green  with  extremely 
narrow  lateral  and  apical  rufous  border..  Antennae  and  palpi  entirely  pale.  Front 
with  moderately  deep  arcuate  groove  within  the  insertion  of  the  antennse,  another 
near  the  edge.  Thorax  as  wide  as  the  head  including  the  eyes,  as  broad  as  long, 
augulate  in  front  of  middle,  the  sides  anteriorly  feebly  arcuate,  posteriorly  sinuate, 
hind  angles  acute.  Elytra  moderately  deeply  striate,  the  striae  finely  punctured, 
intervals  slightly  convex,  smooth.  Legs  rufo-testaeeous.  Length  .20 — .25  inch ; 
5—6.25  mm.     PI.  IV,  fig.  4. 

Three  specimens  without  sexual  difierences  are  before  me,  collected  by 
Hubbard  and  Schwarz,  near  Lake  Poinsett,  Florida. 

It  appears  to  resemble-  0.  hicolor  Chd.,  but  is  larger  and  the  pale 
border  of  the  elytra  is  extremely  narrow.  Among  our  Lebiini  it  wUl 
be  at  once  known  by  the  angulate  sides  of  the  thorax  and  distinct 
hind  angles. 

A  fuller  description  of  tlie  genus  (which  is  placed  by  Chaudoir  in 
the  Callidides),  will  be  given  in  a  future  essay  on  the  species  of  the 
present  tribe. 

In  concluding  the  Lebiini  I  regret  to  believe  that  the  genera  have 
been   inordinately  multiplied,  and  the  higher  divisions  whether  called 


160  GEO.    H.    HORN,    M.  D. 

groups,  tribes,  or  sub-families,  have  become  so  numerous  and  are  based 
on  such  shadowy  characters  as  to  envelope  the  subject  in  an  almost 
impenetrable  cloud. 

Tribe  XXXV.-Helluonini. 

Antennse  moderate  in  length,  rather  stout,  usually  compressed  arising  under 
a  distinct  frontal  plate,  all  the  joints  more  or  less  pubescent,  two  or  four  at  the 
base  less  densely,  first  joint  stout,  equal  in  length  to  the  next  two.  Head  broadly 
oval,  not  narrowed  in  front  of  the  eyes,  with  a  distinct  neck  more  or  less  abruptly 
formed,  clypeus  moderately  prolonged,  a  setigerous  puncture  at  each  side,  front 
with  two  supra-orbital  setigerous  punctures.  Eyes  round,  moderately  prominent, 
close  to  the  mouth  beneath.  Labrum  usually  large  and  prominent,  more  or  less 
concealing  the  mandibles,  sexsetose  in  front.  Mandibles  stout,  arcuate,  rarely 
prominent,  acute  at  tip.  Mentum  broad,  deeply  emarginate  usually  toothed, 
ligula  prominent,  bisetose  at  tip,  the  paraglossfe  adherent  to  the  sides  rarely 
[Polystichus)  longer  than  it  and  usually  semicorneous,  the  palpi  of  moderate 
length,  the  terminal  joint  elongate-oval  or  fusiform  and  obtuse  at  tip,  the  penulti- 
mate bisetose  in  front.  Maxillae  hooked  at  tip,  ciliate  or  spinous  within  the  outer 
lobe  rather  stout,  biartieulate,  the  palpi  stout,  the  terminal  joint  oblong-oval 
truncate  at  tip,  more  or  less  flattened.  Thorax  more  or  less  cordate,  sides  and 
hind  angles  with  a  distinct  setigerous  puncture.  Elytra  oblong,  truncate  at  apex, 
base  not  margined,  sides  narrowly  infiexed,  margin  entire,  disc  striate  or  broadly 
sulcate,  without  dorsal  punctures.  Prosternum  not  prolonged.  Mesosternal  epi- 
mera  narrow.  Metasternal  epimera  distinct,  the  posterior  coxse  contiguous.  Legs 
moderate  in  length,  the  anterior  femora  more  or  less  clavate.  Tibife  sometimes 
(Helluomorpha)  compressed  and  finely  bicarinate  on  the  outer  edge,  the  anterior 
rather  stout  and  broad,  deeply  emarginate  within,  spurs  moderate  in  length. 
Tarsi  moderate  in  length  usually  ciliate  above,  the  fourth  joint  either  entire, 
emarginate  or  even  bilobed.     Claws  simple. 

The  anterior  tarsi  of  the  male  are  rarely  broader  than  the  female. 

This  tribe  is  the  equivalent  of  the  Helluonides  of  Lacordaire,  to  which 
I  add  PoJi/stichus. 

The  form  of  the  ligula  has  been  almost  the  entire  reliance  in  the 
separation  of  this  tribe  from  the  other  Truncatipennes,  but  the  method 
usually  adopted  in  describing  the  ligula  as  having  no  paraglossge  is 
entirely  erroneous.  Although  the  labium  (which  term  includes  the 
entire  organ,  ligula  and  paraglossse),  is  almost  entirely  corneous  in  the 
majority  of  genera,  the  parts  which  compose  it  are  as  evident  as  in  A<jra 
in  which  the  whole  organ  is  almost  entirely  membranous. 

Polystichus  is  added  from  the  Dryptini,  as  it  lacks  the  palpar  structure 
which  is  characteristic  of  that  tribe ;  it  has  moreover  the  front  parallel 
before  the  eyes,  forming  a  plate  over  the  antennas,  the  anterior  legs 
rather  stout  and  the  antennas  distinctly  compressed.  These  latter  are 
decided  characters  approaching  it  to  the  present  tribe.  It  is  however  one 
of  those  forms  which  should  be  placed  in  the  position  of  an  intermediate.

being  membranous,  a  little  longer  than  the  ligula,  arcuate,  obtuse  and 
finely  ciliate.  In  the  general  form  of  body,  especially  the  thorax, 
Folystichus  resembles  very  greatly  Helluoviorpha. 

The  latter  genus  is  the  only  one  known  to  inhabit  our  fauna. 

Helluodes  Westw.,  placed  by  him  in  the  present  tribe  does  not  belong 
here,  it  is  evidently  allied  to  Anthia. 

Tribe  XXXVI.— Graphipterini. 
Antennse  more  or  less  compressed,  arising  at  a  distance  beneath  a  slight  frontal 
ridge,  three  basal  joints  glabrous,  third  joint  eqnal  in  length  or  a  little  longer  than 
the  next  two  together.  Head  with  front  deflexed,  two  supra-orbital  setie,  heck 
stout,  clypeus  slightly  prolonged,  a  setigerous  puncture  each  side.  Eyes  oval  in 
the  axis  of  the  head,  very  distant  beneath  from  the  buccal  iissure.  Labrum 
moderately  prominent,  arcuate  in  front  but  slightly  emarginate  at  middle,  sex- 
setose.'  Mandibles  moderately  stout,  arcuate  near  the  tip  which  is  acute,  inner 
edge  with  slight  tooth  behind  the  middle,  outer  edge  without  setigerous  puncture. 
MaxilltB  hooked  at  tip,  coarsely  and  densely  ciliate  within,  outer  lobe  biarticulate, 
the  terminal  joint  a  little  longer,  palpi  moderate  in  length  the  last  two  joints 
nearly  equal,  the  tenninal  slightly  oval  and  truncate  at  tip.  Mentum  deeply 
emarginate,  not  toothed  but  with  the  bottom  of  the  emargination  slightly  promi- 
nent, ligula  moderately  prominent,  elongate-oval,  bisetose  at  tip,  the  paraglossse  . 
broad,  membranous,  adherent  in  tlieir  entire  length  and  meeting  by  a  narrow 
band  at  the  apex  of  the  ligula,  palpi  moderate  in  length,  the  terminal  joint 
cylindrical,  arcuate,  slightly  stouter  at  middle,  truncate  at  tip,  shorter  than  the 
preceding  which  is  plurisetose  in  front.  Thorax  variable  in  form,  cordate  or 
trapezoidal,  margin  acute,  sides  without  setigerous  punctures.  Elytra  not  mar- 
gined at  base,  broadly  oval  or  suborbicular,  feebly  convex,  apex  truncate,  margin 
acute,  no  internal  plica,  the  ocellate  punctures  of  the  margin  indistinct  (or  entirely 
wanting  ?).  Prosternum  acute  at  tip,  not  prolonged.  Mesosternum  oblique,  the 
epipaera  extremely  narrower.  Metasternal  epimera  distinct,  posterior  coxse  con- 
tiguous. Legs  slender  moderately  long.  Tibife  with  the  outer  edge  sulcate  in  its 
entire  length  and  spinulose,  the  anterior  emarginate  within,  the  inner  spur  remote 
from  the  apex.  Posterior  tibia?  with  the  terminal  spurs  dissimilar,  the  inner  very 
slender,  the  outer  cylindrical,  compressed,  and  obliquely  truncate  at  apex.  Tarsi 
slender  with  stiff  bristles  beneath,  those  at  the  tips  of  the  joints  long.  Claws  very 
slender,  simple.     Body  winged  or  not. 

The  males  have  three  joints  of  the  anterior  tarsi  slightly  dilated  with  narmw 
squamules  beneath. 

This  tribe  which  is  essentially  African  contains  but  two  genera, 
Graphipterus  and  Piezia.  As  Lacordaire  correctly  observes  they  are 
in  most  respects  Truncatipennes,  but  if  the  ligular  characters  were  given 
full  power  the  two  genera  would  be  found  in  a  very  uncomfortable 
position  in  the  Lebiide  series. 

It  will  be  observed  that  the  setigerous  punctures  of  the  upper  surface 
are  reduced  almost  to  the  mininuim  and  the  supra-orbital  seta3  are  never 
long,  often  inconspicuous.  In  quite  a  number  of  specimens  which  have 
been  examined  no  thoracic  setoe  have  been  observed.

The  dissimilarity  of  the  spurs  of  tlie  hind  tibia3  is  a  character  which 
I  do  not  remember  having  observed  elsewhere  in  the  Carabidae. 

The  Graphipterini  and  Anthiini  form  together  an  isolated  group  of 
genera  with  very  little  aflfinity  with  the  other  groups. 

Tribe  XXXVII.— Anthiini. 
Anteniife  moderately  robust  and  long,  the  base  free,  three  basal  joints  glabrous, 
tiiird  joint  as  long  as  the  first.  Head  large  sometimes  slightly  constricted  behind 
the  eyes,  the  neck  usually  stout,  two  supra-orbital  setigerous  punctures.  Eyes 
moderately  prominent,  oval  in  the  axis  of  the  head,  very  distant  beneath  from 
tlie  mouth,  the  gente  usually  dilated.  Clypeus  moderately  j)rolonged,  truncate  or 
broadly  emarginate,  a  setigerous  puncture  each  side.  Labrum  large,  prominent, 
convex  above*  anterior  jnargin  with  four  or  six  setse.  Mandibles  usually  variable 
in  the  sexes,  more  elongate  in  the  males,  arcuate  and  acute  at  tip  without  setiger- 
ous puncture  on  the  outer  side.  Maxillae  relatively  slender,  hooked  at  tip,  densely 
ciliate  within,  the  outer  lobe  biarticulate,  the  terminal  joint  a  little  longer,  the 
palpi  rather  stout,  the  terminal  joint  slightly  flattened,  broader  to  tip  and  truncate. 
Mentum  very  deeply  emarginate  without  tooth,  the  palpi  stout  the  terminal  joint 
much  shorter  and  more  slender  than  the  second,  this  plurisetose  in  front,  ligula 
variable  usually  long  and  dilated  in  oval  form  witli  three  short  setas  on  each  side, 
the  paraglossse  short  and  corneous.  Thorax  cordiform  or  somewhat  hexagonal 
and  angulate  at  the  sides  with  a  setigerous  puncture  at  the  most  prominent  part 
of  the  sides  and  none  at  the  hind  angle.  Body  subpedunculate,  scutellum  small. 
Elytra  not  margined  at  base,  sides  narrowly  inflexed,  margin  entire,  no  internal 
plica,  apices  usually  obliquely  sinuate,  the  sutural  angle  often  prominent.  Pro- 
sternum  not  prolonged.  Mesosternum  convex  in  front,  the  epimera  very  narrow. 
Metasternal  epimera  distinct,  posterior  coxse  usually  separated,  sometimes  however 
but  narrowly.  Legs  moderately  long.  Tibiae  very  feebly  spinous  and  not  suleate 
on  the  outer  edge,  the  anterior  moderately  emarginate  on  the  inner  side,  the  inner 
spur  remote  from  the  apex.  Spurs  of  posterior  tibise  slender  and  similar.  Tarsi 
usually  flattened,  the  first  joint  as  long  as  the  next  three,  the  fourth  more  or  less 
emarginate,  beneath  spinous.     Claws  long,  simple. 

The  males  have  three  joints  of  the  anterior  tarsi  moderately  dilated  and  ciliate 
and  spinous  beneath. 

There  are  also  sexual  characters  in  the  mandibles  and  the  thorax  is 
often  prolonged  behind  in  two  lobes  in  the  males. 

The  ligula  is  described  as  having  no  paraglossa^,  but  this  is  certainly 
incorrect  and  these  members  will  be  fovind  by  dissection  as  I  have 
figured  them  (105). 

The  genera  of  this  tribe  occur  in  xlfrica.  They  seem  to  bear 
the  same  relation  to  the  (rraphipterini  that  the  Anchonoderini  do  to 
the  Lebiini. 

Closely  related  to  the  present  and  preceding  tribes  are  two  genera 
Helluodes  and  Pht/soa-ofaphus,  which  should  probably  form  a  distinct 
tribe  to  be  placed  between  the  Anthiini  and  Graphipterini.  Lacordaire 
places  the  former  genus  in  his  Helluonides  (ante  p.  IGO),  the  latter  in 
the  Morionides  (ante  p.  133).      T  have  studied  Helluodes  in  nature  and

had  I  sufficient  details  of  the  other  genus  would  have  defined  the  tribe 
as  indicated.  The  structure  of  the  labial  palpi  is  that  of  the  present 
tribe  and  the  ligula  of  nearly  the  same  type,  the  paraglossae  are  however 
more  developed. 

Tribe  XXXVIII.— Cratocerini. 
Antennse  shorter  than  the  head  and  thorax,  inserted  under  a  sliglit  frontal 
ridge  with  however  the  condyle  visible,  three  basal  joints  glabrous,  4 — 11  com- 
pressed or  somewhat  moniliform.  Head  short,  not  narrowed  behind  to  a  neck, 
clypeus  slightly  prolonged  and  without  setigerous  punctures,  front  with  the  setiger- 
ous  punctures  over  the  eye  extremely  indistinct.  Ej'es  moderately  prominent, 
close  to  the  mouth  beneath.  Labrum  short  transverse,  feebly  emarginate  and 
sexsetose  in  front.  Mandibles  moderately  robust,  arcuate,  acute  at  tip.  Maxillae 
ciliate  within,  (the  inner  lobe  not  hooked  in  Basolia),  the  outer  lobe  slender, 
biarticulate,  the  palpi  rather  stout,  the  last  joint  oval  rather  obtuse.  Mentum 
transverse,  deeply  emarginate  and  toothed,  the  lateral  lobes  obtuse,  obliquely 
truncate,  ligula  feebly  prominent,  tip  free  for  a  short  distance  and  arcuate,  bisetose, 
paraglossiB  semicorneous,  not  longer  than  the  ligula  (spinuluse  at  tip  in  Basolia), 
and  united  to  the  ligula  by  a  translucent  membrane,  palpi  rather  slender,  the 
last  two  joints  equal  in  length  the  penultimate  bisetose  in  front.  Thorax  more  or 
less  quadrate,  not  narrowed  at  base,  the  setigerous  punctures  entirely  obliterated. 
Elytra  not  wider  at  base  than  the  thorax,  sides  narrowly  inflexed,  margin  entire, 
apices  truncate  or  rounded,  surface  striate,  without  scutellar  stria,  dorsal  punc- 
tures ?.  Prosternum  not  prolonged.  Mesosternal  epimera  narrow.  Metasternal 
epimera  distinct,  posterior  coxae  contiguous.  Legs  rather  stout,  the  tibiae  not 
carinulate,  the  spurs  rather  small,  the  anterior  tibiae  dilated  at  tip,  the  outer  angle 
rounded,  inner  side  deeply  emarginate.     Tarsi  rather  stout,  claws  simple. 

The  anterior  tarsi  of  the  males  have  four  joints  moderately  dilated  and  biseri- 
ately  squamulose  beneath. 

I  regret  that  I  can  only  imperfectly  formulate  the  characters  of  this 
tribe.  I  know  only  one  specimen  of  Basolia  nitida  Sol.  It  may  be 
almost  unnecessary  to  state  that  the  tribe  is  not  the  equivalent  of 
Lacordaire's  Cratocerides  which  equals  nearly  the  Dapti  of  the  present 
essay.  Lacordaire  was  unfortunate  in  naming  his  tribe  after  a  genus 
entirely  unknown  to  him  and  which  by  no  means  typified  his  idea 
of  the  tribe. 

To  Baron  Chaudoir  we  are  indebted  for  a  proper  description  of  the 
tribe  and  an  association  of  genera  which  seem  naturally  to  belong 
together,  (Ann.  Belg.  1872).  From  my  own  study  I  would  place  these 
insects  not  far  from  the  Lebiide  series,  the  ligula  even  being  quite 
suggestive  of  that  idea.  I  do  not  perceive  a  close  relationship  with 
the  Morionini  but  rather  with  the  Helluonini. 

The  three  genera  are  Basolia  (=  Catapiesis),  Cratocerus  and  Brach- 
idius,  the  first  two  from ,  Brazil,  the  third  from  the  Philippine  Islands. 
There  is  nothinu'  allied  to  them  in  our  fauna. 


1G4  GEO.    H.    HORN,    M.  D. 

Tribe  XXXIX.— Orthogonini. 

Antennse  of  variable  length,  more  or  less  compressed  beyond  the  third  joint, 
three  basal  joints  glabrous,  inserted  under  a  slight  frontal  ridge,  the  condyle 
however  visible.  Eyes  moderately  prominent,  close  to  the  mouth  beneath.  Head 
short,  oval,  not  constricted,  front  with  two  supra-orbital  setse,  clypeus  moder- 
ately prolonged,  its  front  margin  subcoriaceous,  a  setigerous  puncture  each  side. 
Labrum  quadrangular,  moderately  prominent,  apical  margin  sexsetose.  Mandibles 
slightly  prominent,  arcuate,  acute  at  tip.  MaxilliB  usually  hooked  at  tip,  (except 
Anoncopeucus),  ciliate  within  and  sometimes  at  tip,  the  outer  lobe  slender,  palpi 
moderate  in  length,  last  joint  subcylindrical  or  ovate,  apex  obtuse.  Mentum 
emarginate  without  tooth,  the  emargination  nearly  filled  with  the  basal  membrane 
of  ligula,  the  latter  moderately  prominent,  corneous,  2 — 6  setose  at  tip,  the  para- 
glossse  large,  auriculate,  and  longer  than  the  ligula,  the  palpi  moderate,  the  last 
two  joints  equal,  the  penultimate  bisetose  in  front.  Thorax  broader  than  long, 
lateral  margin  acute,  depressed  and  without  setigerous  punctures.  Elytra  oblong 
usually  depressed,  base  margined,  sides  narrowly  inflexed,  margin  entire,  apex 
usually  truncate  sometimes  almost  rounded,  surface  striate  and  with  three  dorsal 
punctures,  the  first  on  the  second  interval  near  the  third  stria,  the  posterior  two 
near  the  second  stria.  Prosternum  not  prolonged.  Mesosternal  epimera  narrow. 
Metasternal  epimera  distinct,  the  posterior  coxae  contiguous.  Legs  moderately 
stout,  the  tibise  on  the  outer  edge  sulcate  and  carinulate,  the  carinae  crenulate  and 
finely  spinulose;  anterior  tibi«  moderately  stout,  the  outer  apical  angle  acute, 
inner  side  emarginate,  tibial  spurs  moderate  in  length.  Tarsi  moderate  in  length, 
the  fourth  joint  emarginate  or  bilobed,  the  claws  slender,  simple  or  pectinate. 

The  tarsi  on  all  the  feet  are  dilated  in  both  sexes  and  are  either  densely  pubes- 
cent or  densely  papillose  beneath. 

The  only  species  of  this  tribe  that  I  have  been  able  to  procure  for 
dissection  is  Orthogonius  acrogonus  Wied.,  in  which  I  find  the  ligula 
distinctly  free  at  tip,  the  paragloss^  large  and  auriculate  extending 
beyond  the  ligula  and  united  hehind  the  ligula  by  a  thin  translucent 
membrane  (108). 

It  is  interesting  to  find  that  in  this  tribe  we  have  a  genus  with 
the  maxillae  obtuse  at  tip,  a  character  very  irregularly  diff'used  in 
the  Carabida3. 

As  indicated  above  the  elytra  are  variable  at  tip,  being  either  entire 
or  feebly  truncate.  Exceptional  cases  of  this  kind  must  be  expected  in 
so  extensive  a  family. 

In  the  present  tribe  the  characters  seem  to  indicate  an  aberrant 
Truncatipenne  with  decided  Harpalide  affinities,  Gh/ptus  forming  a  link 
in  the  line  of  affinity.  As  Zabrus  seems  to  be  the  link  between  the 
Fteroaticliini  and  Harpalini,  so  Orthogonius  is  between  the  Truncati- 
penne complex  and  the  Harpalini. 

An  interesting  essay  on  this  tribe  by  Baron  Chaudoir  will  be  found 
in  the  Annales  de  la  Soe.  Ent.  Belg.  xiv,  pp.  95 — 130,  in  which  will  be 
found  an  expression  of  opinion  very  nearly  the  same  as  that  above. 


AMERICAN    COLEOPTERA.  165 

Harpalin^  UNISETOS^. 

This  section  is  not  by  any  means  as  large  as  the  preceding,  the  tribes 
numbering  only  a  third  and  the  genera  even  less  proportionately  numerous. 
The  essential  character  of  this  section  is  the  presence  of  but  one  supra- 
orbital seta.  This  carries  with  it  the  tendency  to  a  loss  of  the  seta  at 
the  hind  angle  of  the  thorax,  in  fact  the  existence  of  this  seta  either  at 
or  near  the  hind  angle  is  more  of  au  exception  here  than  its  absence  is 
in  the  Harpalinse  bisetosse. 

The  elytral  plica  exists  in  some  of  the  tribes  here  and  in  about  the 
same  proportion  as  in  the  preceding  section,  and  it  is  by  this  means  that 
we  can  trace  some  affinity  with  Pterostichini  on  the  one  side  or 
L  6  b  i  i  n  i  on  the  other. 

The  setigerous  puncture  on  the  outer  side  of  the  mandible  is  also 
observed  here  in  a  relatively  greater  number  of  tribes  but  in  far 
fewer  genera. 

Of  the  eight  tribes  which  follow  six  have  representation  in  our  fauna, 
the  Apotomini  and  P e  1  e c i i n i  being  absent,  while  Z  a c o t i n  i 
is  peculiar  to  it. 

Mesosternal  epimera  usually  wide,  sometimes  nearly  as  large  as  the  episterna, 
elytra  truncate.  Mandibles  with  setigerous  puncture.  Posterior  coxse 
often  separated,  the  first  ventral  segment  risible  between  them. 

Tribe  XL.  Brachynini. 
Mesosternal  epimera  very  narrow  and  indistinct,  elytra  always  entire. 
Mandibles  with  setigerous  puncture  on  the  outer  side.     Abdomen  peduncuhite. 
Thorax   not   margined   at   the   side,   its   sutures   beneath   obliterated.     Middle, 
and  posterior  tibice  emarginate  on  outer  edge  at  tip.     Antennae  with  two 
glabrous  joints.     Posterior  coxse  separated.     Labial  and  maxilhuv  palpi 

elongate ; Tribe  XLL  Apotomini. 

Thorax  margined,  sutures  distinct.     Middle  and  posterior  tibiae  not  emarginate. 
Palpi  not  long.     Posterior  coxse  contiguous  or  but  narrowly  separated. 

Tril)e  XLII.  Broscini. 
Mandibles  without  setigerous  puncture. 
Posterior  coxse  distinctly  separated. 

Bod}'^  pedunculate.     Elytra  not  margined  at  base Tribe  XLIII.  Zacotini. 

Body  not  pedunculate.     Elytra  margined  at  base Tribe  XLIV.  Peleciini. 

Posterior  coxse  contiguous. 

Elytral  margin  more  or  less  interrupted  and  witli  an  internal  plica.    Antennae 
with  three  glabrous  joints. 
Anterior   tarsi  of  male  with   three,   rarely  four,  joints   spongy  pubescent 

beneath.     Elytral  plica  feeble Tribe  XLV.  Chlaeniini. 

Anterior  tarsi  of  male  with  thi-ee  joints  dilated  and  squamulose  beneath. 

Elytral  plica  strong Tribe  XLVI.  Zabrini. 

Elytral  margin  not  interrupted,  no  internal  plica.    Antennse  with  two,  rarely 
with  three,  glabrous  joints.     The  male  tarsi  variable. 

Tribe  XLVIL  Harpalini. 


(a7) 


166  GEO.    H.    HORN,    M.  D. 

Tribe  XL.  — Brachynini. 

Antennae  slender,  the  condyle  of  the  basal  joint  exposed,  two  basal  and  a  portion 
of  the  third  joint  glabrous.  Head  gradually  narrowed  behind  the  eyes  forming 
a  neck,  front  with  one  supra-orbital  seta,  clypeus  moderately  prolonged.  Labrum 
broad,  truncate.  Eyes  oval,  oblique,  narrowly  separated  from  the  buccal  open- 
ing. Mandibles  stout,  feebly  arcuate  and  with  a  setigerous  puncture  externally. 
Maxillse  hooked  at  tip,  ciliate  within  and  at  the  tip,  the  outer  lobe  slender, 
%vith  equal  joints,  the  palpi  moderate,  the  last  two  joints  more  or  less  pubescent. 
Mentum  moderately  broad,  emarginate,  toothed  or  not,  the  ligula  in  great  jjart 
membranous,  the  oval  centre  corneous  and  bisetose  at  tip,  the  paraglossse  broad, 
adherent  and  ciliate  at  tip,  the  palpi  moderate  in  length,  the  second  joint  longer 
than  the  last  and  plurisetose  in  front.  Thorax  with  short  marginal  setse,  no  special 
seta  at  the  hind  angle.  Scutellum  distinct.  Elytra  not  margined  at  base,  narrowly 
inflexed,  margin  not  interrupted,  no  internal  plica,  apex  truncate  and  with  a 
membranous  border,  disc  not  striate  and  without  dorsal  punctures.  Prosternura 
not  prolonged  at  tip.  Mesosternal  epimera  broad.  Metasternal  epimera  distinct, 
the  posterior  cox£e  either  contiguous  or  separated.  Middle  and  posterior  tibiae 
finely  ciliate  or  spinulose  externally,  the  anterior  deeply  emarginate  within,  the 
inner  spur  at  the  summit  of  the  emargination.  Tarsi  slender,  the  fourth  joint 
feebly  emarginate,  the  anterior  of  the  males  with  three  joints  feebly  dilated  and 
squamulose  beneath. 

This  is  one  of  tlie  tribes  the  composition  of  which  seems  at  present 
free  from  differences  of  opinion.  Its  position  among  the  other  tribes 
seems,  however,  far  from  settled,  and  I  would  merely  suggest  that  it  be 
placed  after  the  Graphipterini  for  want  of  a  better  place  although  its 
wide  mesosternal  epimera  exclude  it,  not  only  from  any  intimate  associa- 
tion with  these,  but  also  any  of  the  tribes  of  the  present  sub-family 
excepting  the  Ozsenini  and  the  two  adjacent  tribes.  With  the  latter  it 
can  hardly  be  said  to  have  much  affinity. 

The  only  genus  occurring  in  our  fauna  is  Brachynus  and  to  this  it  is 
necessary  to  direct  our  attention.  In  the  general  diagnosis  the  posterior 
coxae  are  said  to  be  either  contiguous  or  separated.  It  will  be  observed 
in  the  larger  species  that  many  of  the  specimens  have  the  coxae  plainly 
contiguous,  the  smaller  species  have  the  coxae  separated  and  in  the  case 
of  carinulatus  rather  widely,  so  that  in  the  present  genus  a  character 
shrinks  into  insignificance  which  ifi  other  parts  of  the  series  is  of  the 
highest  importance.  This  is  one  of  the  few  instances  known  to  me  in 
the  entire  Carabide  series  in  which  a  really  important  character  ceases  to 
have  its  full  value. 

On  the  other  hand  the  apparent  increase  of  the  number  of  the 
abdominal  segments  to  seven  or  eight  has  been  exaggerated  in  value 
very  far  beyond  its  importance.  If  we  examine  the  species  of  any  of 
the  genera  which  emit  from  the  anus  a  liquid  whether  explosive  or  not,  it 
will  be  seen  that  the  structure  in  no  way  differs  from  that  of  Brach/nus 
except  that  the  latter  has  a  broader  sixth  segment  which,  being  truncate 


AMERICAN    COLEOPTERA.  167 

or  slightly  emarginate,  allows  the  genital  armature  to  become  more 
plainly  visible  and  we  thus  count  more  segments.  Galerita  and  any 
of  the  larger  Dryptini  will  illustrate  the  above  ideas. 

The  species  of  Brachynua  are  found  under  logs  and  stones  usually 
in  damp  situations  and  often  in  colonies.  Those  in  our  fauna  have  the 
head,  thorax  and  legs  yellowish,  the  elytra  blue.  They  have  not  yet 
been  separated  in  any  satisfactory  manner. 

Tribe  XLI. — Apotomini. 
Antennse  slender  arising  under  a  slight  frontal  ridge,  two  basal  joints  glabrous', 
third  very  little  longer  than  the  fourth.  Head  broader  behind  the  eyes,  front 
with  one  supra-orbital  seta,  elypeus  moderately  prolonged.  Labruni  short,  trun- 
cate. Eyes  oval,  not  prominent,  narrowly  separated  from  the  mouth  beneath. 
Mandibles  arcuate,  acute  at  tip  and  with  a  .setigerous  puncture  extei'nally.  Maxillte 
hooked  at  tip,  ciliate  within,  the  outer  lobe  rather  slender,  biarticulate,  the  palpi 
very  long  and  slender,  the  joints  hairy,  the  last  shorter  than  the  preceding  and 
pubescent.  Mentum  broad,  feebly  emarginate  without  tooth,  ligula  moderately 
prominent,  rounded  at  tip  and  with  four  long  setse,  the  paraglossse  adherent, 
a  little  longer  than  the  ligula  and  obtuse  at  tip,  the  palpi  slender,  second  joint 
plurisetose  in  front,  last  joint  a  little  shorter,  slender,  acute  at  tip  and  hairy. 
Thorax  globular,  truncate  in  front,  tubularly  prolonged  at  base,  sides  not  margined, 
sutures  entirely  obliterated,  sides  with  but  one  setigerous  puncture  at  middle, 
none  at  hind  angle.  Body  subpedunculate,  scutellum  very  small.  Elytra  oblong, 
sides  narrowly  inflexed,  obliquely  sinuate  near  the  tip  which  is  somewhat  pro- 
longed, no  internal  plica  and  no  marginal  ocellate  punctures  and  no  dorsal  punc- 
tures. Presternum  not  prolonged  at  tip.  Mesosternum  nearly  vertical  in  front, 
the  eoxse  rather  widely  separated,  the  epimera  narrow  and  indistinct.  Metasternal 
epimera  distinct.  Posterior  coxae  rather  widely  separated,  the  first  ventral  segment 
distinctly  visible  between  them.  Femora  stout,  especially  the  anterior.  Tibise  not 
ciliate  or  spinulose,  the  anterior  deeply  emarginate  within,  the  inner  spur  superior, 
middle  and  posterior  tibiae  obliquely  grooved  a)id  emarginate  at  the  outer  apical 
angle.     Tarsi  slender  in  both  sexes,  claws  simple. 

This  ti-ibe  contains  only  Apotomus  which  occurs  in  Europe,  East 
Indies  and  Australia.  It  has  been  placed  near  Bemhidhtm  and  Scarites 
by  Latreille.  Dejean  removed  it  to  the  Ditomides  in  which  position 
Lacordaire  leaves  it.  Duval  (Genera  i.  p.  43),  recognizing  its  want  of 
affinity  with  these,  forms  of  it  a  distinct  tribe  which  he  places  between 
the  Clivinites  and  Ditomites,  a  line  of  affinities  which  seems  as  unnatural 
as  any  that  could  have  been  chosen.  It  seems  to  me  better  placed  near 
the  Broscini  as  one  of  the  most  sharply  defined  tribes  of  the  sub-family. 

Tribe  XLIL— Broscini. 

Anteuufe  moderate  in  length  with  a  variable  number  (three  to  five)  of  basal 
joints  glabrous.  Head  not  constricted  but  usually  gradually  broader  behind  the 
eyes,  front  not  sulcate,  one  supra-orbital  setigerous  puncture  and  often  with  a  post- 
orbital  cicatrix.  Eyes  oval,  distant  beneath  from  the  mouth.  Clypeus  moderately 
prolonged  with  lateral  setse.    Labrum  moderately  prominent,  slightly  emarginate. 


1<)8  GEO.    H.    HORN,    M.  D. 

Mandibles  arcuate  at  tip  with  a  setigerous  puncture  on  the  outer  side.  Maxillge 
with  the  inner  lobe  hooked  at  tip,  ciliate  or  spinulose  within,  outer  lobe  moderately 
stout,  biarticulate,  the  palpi  rather  stout,  the  last  joint  longer  than  the  third, 
elongate-oval  or  fusiform.  Mentum  broad,  deeply  emarginate,  toothed  or  not.  the 
ligula  moderately  prominent,  truncate  and  bisetose  at  tip,  the  paraglossse  adherent, 
sometimes  free  for  a  short  distance  and  rarely  longer  than  the  ligula,  the  palpi 
rather  stout,  the  last  joint  a  little  longer  than  the  second,  more  or  less  oval  in 
shape,  (impressed  beneath  in  Miscodera) ,  the  second  joint  bisetose  in  front.  Thorax 
more  or  less  ovoid,  the  sides  narrowly  margined  and  bisetose,  the  posterior  seta  in 
front  of  the  hind  angles.  Body  pedunculate,  scutellum  in  the  peduncle.  Elytra 
not  margined  at  b^se,  sides  narrowly  inflexed,  margin  not  interrupted  posteriorly 
but  with  a  short  internal  plica,  disc  without  dorsal  punctures.  Prosternum  obtuse 
at  tip.  Mesosternum  rather  wide,  oblique,  the  epimera  narrow.  Metasternal 
epimera  distinct,  posterior  coxse  contiguous  or  very  narrowly  separated.  Legs 
moderately  stout,  the  tibise  not  spinulose  externally,  the  anterior  moderately 
dilated  at  tip,  deeply  emarginate  within,  the  inner  spur  at  the  upper  angle  of  the 
emargination.     The  tarsi  filiform,  fourth  joint  simple. 

The  anterior  tarsi  of  the  males  may  have  four,  three  or  two  joints  dilated,  their 
vestiture  usually  hairs,  rarely  squamules. 

The  creation  of  this  tribe  under  the  name  of  Cnemacanthides  is  due 
to  Lacordaire.  Dioctea  has  been  removed  by  Schaum  (Ins.  Deutschl.  i, 
p.  353),  to  the  Ditomides,  but  Promecogvathus  was  added,  the  mistake, 
however,  having  been  corrected  on  a  subsequent  page,  (p.  773). 

The  Broscini  have  a  sUght  sub-ocular  ridge  at  the  side  of  the  head. 
This  ridge  is  well  marked  in  the  CicindeUdas  but  I  have  not  observed  it 
elsewhere  in  Carabidae. 

The  latest  revision  of  the  tribe  is  by  Putzeys,  (Stett.  Zeit.  1868, 
p.  305 — 379),  who  recognizes  seventeen  genera  and  by  the  characters 
given  of  the  first  six,  some  of  them  might  with  propriety  be  removed 
to  form  a  tribe  between  the  present  and  the  Harpalini. 

In  our  fauna  we  have  but  one  genus  represented  by  two  species. 

MiscoDERA  Esch. — In  form  the  species  resemble  a  large  Di/schirius. 
The  two  species  are  : 

M.  ARCTICA  Payk. — Occurs  in  northern  Europe  and  in  Siberia  where 
it  has  received  the  name  erythrojpus  Mots.,  crossing  to  Alaska  it  becomes 
americana  Mann.,  and  it  finally  reaches  Newfoundland  under  the  name 
Hardi/i  Chaud.  It  is  all  one  species  varying  in  size  and  brilliancy  of 
surface  in  the  different  localities. 

M.  INSIGNIS  Mann.,  is  altogether  different.  The  anterior  half  of  the 
thorax  is  ovate,  the  basal  half  prolonged,  somewhat  like  Promecognatlms. 
It  occurs  in  Alaska. 

I  have  in  the  next  tribe  given  my  reasons  for  removing  Zacotiis,  and 
in  the  same  place  and  in  Peleciini  will  be  found  remarks  on  the  affinities 
of  these  two  tribes  with  the  present.

Tribe  XLIII.— Zacotini. 
Antenna  filiform  arisine;  under  a  slight  frontal  margin,  first  joint  stouter, 
cylindrical,  third  a  little  longer  than  the  following,  the  first  four  joints  glabrous. 
Head  subquadrangular,  slightly  constricted  at  a  distance  behind  the  eyes,  a  distinct 
temporal  cicatrix,  front  with  one  supra-orbital  seta,  clypeus  slightly  prolonged  and 
with  the  usual  setigerous  puncture  each  side.  Eyes  round,  moderately  prominent 
and  distant  from  the  buccal  fissure  beneath.  Labrum  transverse  feebly  emargin- 
ate,  sexsetose  in  front.  Mandibles  not  prominent,  arcuate  at  tip  only,  acute  and 
without  setigerous  puncture  externally.  Maxillse  eiliate  within,  hooked  at  tip, 
the  outer  lobe  rather  stout,  biarticulate  ;  palpi  stout,  the  last  joint  shorter  than  the 
preceding,  oval  and  truncate  at  tip.  Mentum  transverse,  emarginate  and  acutely 
toothed,  the  epilobes  acute  and  prominent;  ligula  moderately  prominent,  tip 
arcuate  and  free  with  two  setre,  paraglossfe  free  for  a  short  distance  at  tip  which 
is  acute,  shorter  than  the  ligula;  palpi  moderate,  third' joint  elongate-triangular, 
slightly  arcuate,  truncate  at  tip,  the  preceding  joint  shorter  and  bisetose  in  front. 
Thorax  ovate,  slightly  constricted  behind,  margin  distinct,  two  lateral  setse,  one 
near  the  middle,  one'  in  front  of  base.  Body  pedunculate,  scutellum  not  visible. 
Elytra  oblong-oval,  humeri  rounded,  base  not  margined,  sides  narrowly  inflexed, 
margin  entire  not  interrupted  posteriorly  without  internal  plica.  Prosternum  not 
prolonged.  Mesosternum  obtuse  in  front,  rather  widely  separating  the  coxae,  the 
epimera  distinct,  broader  externally.  Metasternum  short,  body  apterous,  epimera 
distinct,  posterior  coxse  slightly  separated.  Legs  rather  slender,  middle  tibise 
slightly  spin-ulose  externally  near  the  tip,  anterior  tibife  moderately  dilated, 
emarginate  internally,  the  inner  spur  at  tlie  upper  angle  of  the  notch.  Tarsi 
slender,  the  fourth  joint  simple. 

The  males  have  four  joints  of  the  anterior  tarsi  quadrangularly  dilated,  the  first 
three  with  squamiform  papilla;  beneath,  the  middle  tarsi  are  not  dilated  but  the 
first  two  joints  are  squamulose  beneath. 

While  I  regret  the  muUiplication  of  tribes  I  aui  unwilling  to  place 
Zacotus  either  in  the  Broscini  or  Peleciini,  and  uiu8t  therefore  make  it 
the  type  of  a  separate  tribe. 

In  size  and  general  appearance  (except  the  head)  it  resembles  J'rome- 
coderus  concolor  Germ.  The  head  is  subquadrangular,  slightly  pro- 
longed behind  the  eyes  and  then  constricted  but  to  a  less  degree  than  in 
Pelecium,  the  front  has  similar  longitudinal  depressions  but  less  marked. 
The  body  is  pedunculate  as  in  the  Broscini  but  the  palpi  are  more  nearly 
those  of  Felecium.  The  maxilkc  are  hooked  at  tip  in  Zacotus  and  the 
Broscini,  not  hooked  in  Pelecium.  The  niandibles  have  no  setigerous 
puncture. 

Zacotus  seems  therefore  to  form  a  tribe  with  nearly  e(|ual  relations 
with  the  Broscini  and  Peleciini,  and  to  indicate  that  these  two  tribes  are 
far  more  closely  allied  than  any  one  has  yet  admitted. 

But  one  species  Z.  Matthewsii  Lee,  occurs  in  Washington  Territory 
and  Vancouver.  I  am  informed  by  Mr.  Morrison  that  it  lives  near 
small  streams  in  dense  woods.  It  is  piceous  with  bright  :>3neous  or 
cupreous  surface  lustre.

Tribe  XLIV.— Peleciini. 
AntennsB  moderately  long,  filiform,  arising  under  a  distinct  frontal  ridge,  first 
joint  stout,  a  little  longer  than  the  others,  2—11  subequal,  the  first  three  joints 
glabrous.  -  Head  quadrangular,  suddenly  narrowed  at  a  distance  behind  the  eyes 
to  a  neck  which  broadens  in  a  semiglobular  manner,  front  with  one  supra-orbital 
seta  and  with  a  cicatrix  behind  the  eye,  clypeus  moderately  prolonged  and  without 
lateral  setigerous  punctures.  Eyes  small,  oval,  and  very  distant  from  the  buccal 
opening.  Labrum  transverse,  concave  and  emarginate,  with  six  setse,  the  outer 
one  on  each  side  vertical  and  longer,  functionally  replacing  the  clypeal  seta. 
Mandibles  stout,  prominent,  decurved,  arcuate,  acute  at  tip,  without  external 
setigei-ous  puncture.  Maxillae  slender  not  hooked  at  tip,  ciliate  within,  outer  lobe 
slender,  biarticulate,  the  palpi  stout,  the  outer  joints  setose,  the  terminal  joint 
securiform  or  oval-truncate.  Mentum  transverse,  the  lateral  lobes  obtuse  at  tip, 
emarginate  with  an  acute  tooth  as  long  as  the  lateral  lobes.  Ligula  moderately 
prominent,  arcuate  or  truncate  in  front  and  bisetose,  the  paraglossse  adherent  at 
the  sides,  free  and  slender  at  their  tips  and  ciliate  within,  palpi  stout,  terminal 
joint  longer  tlian  the  second,  securiform  or  oval-truncate,  second  joint  bisetose 
in  front.  Thorax  margined  at  the  sides  and  with  two  setigerous  punctures,  the 
posterior  distant  from  the  hind  angles.  Body  not  pedunculate,  scutellum  more 
or  less  distinct.  Elytra  more  or  less  distinctly  margined  at  base,  the  humeri 
prominent,  fifth  interval  at  base  often  subcarinate,  sides  narrowly  inflexed,  margin 
slightly  interrupted  posteriorly  but  Avith  a  well  marked  internal  carina,  disc 
without  dorsal  punctures.  Presternum  not  prolonged  at  tip.  Mesosternum  obtuse 
in  front,  the  epimera  very  narrow.  Metasterual  epimera  very  indistinctly  sepa- 
rated, the  posterior  coxse  separated  rather  widely,  the  first  ventral  segment  visible 
at  middle.  Legs  moderately  robust,  the  tibiae  not  ciliate  or  spinulose  externally, 
the  anterior  moderately  wide,  deeply  emarginate  internally,  the  inner  spur  remote 
from  apex  but  situated  posteriorly.  Tarsi  not  slender,  the  fourth  emarginate 
or  bilobed. 

The  tarsi  of  the  front  and  middle  legs  have  four  joints  dilated  and  densely 
pubescent  beneath  in  ))oth  sexes,  tlie  males  have  sometimes  the  middle  tibiae 
arcuate. 

This  tribe  contains  but  one  genus  Pelecium  Kby.,  (Eripus  BcJ., 
Augasmosomus  Chd.'),  with  the  species  extending  froui  Mexico  to  Brazil, 
all  of  which  are  of  moderate  size,  and  some  {ci/anipes  Kby.),  with  the 
elytra  recalling  the  sculpture  of  our  DJrs^lua  Init  more  convex.  No 
member  of  this  tribe  has  been  found  in  our  fauna. 

Kirby  placed  the  genus  between  Cj/chrus  and  Fandgseua  and  is  fol- 
lowed by  others.  Dejean  while  placing  it  among  the  Harpalini  remarks 
that  it  does  not  well  fit  there.  Lacordaire  following  Chaudoir  places 
it  in  a  group  Stomides  which  Schauni  justly  says  has  no  fundamental 
character  and  which  is  in  fact  the  most  heterogeneous  tribe  in  Lacordaire's 
Carabidaj.  Schaum,  however,  while  indicating  that  it  must  form  a  sepa- 
rate group,  (Berl.  Zeitsch.  1860,  pp.  128  and  l'J3),  writes  around  the 
subject  leaving  us  as  much  in  doubt  as  to  its  position  as  before. 

I  do  not  believe  there  can  be  much  doubt  of  the  relationship  of  the 
Peleciini  with  the  Broscini  through  Baripus  and  Zacofus. 


AMERICAN    COLEOPTERA.  171 

It  is  a  singular  character  that  the  set^e  which  are  found  in  the  vast 
majority  of  Carabidae,  arising  either  from  the  middle  of  the  side  of  the 
clypeus  or  from  its  anterior  angle,  should  be  here  (I  speak  especially 
of  P.  cyanipes  Kby.),  functionally  replaced  by  the  lateral  setae  of  the 
labrum,  which,  instead  of  being  directed  to  the  front  in  the  usual 
manner,  arise  vertically  and  are  long.  The  rather  wide  separation  of 
the  posterior  coxas  does  not  appear  to  have  been  noticed.  The  temporal 
cicatrix  to  which  Putzeys  directs  attention  (Stett.  Zeitsch.  1868,  p.  306), 
is  observed  in  Felecium  as  well  as  in  Broscini. 

Tribe  XLV. -Chlaeniini. 

Anteniife  slender,  rarely  slightly  compressed  {Evoknes^  arising  under  a  slight 
frontal  ridge,  the  three  basal  joints  glabrous.  Head  not  narrowed  behind  the  eyes 
to  a  neck,  one  supra-orbital  setigerous  puncture.  Clypeus  more  or  less  prolonged 
between  the  mandibles,  often  without  the  lateral  seta.  Eyes  oval,  moderately 
prominent,  more  truncate  behind  in  the  Oodes.  Labrum  transverse,  truncate 
or  emarginate,  with  three,  four  or  six  setse  in  front.  Mandibles  feebly  arcuate, 
without  setigerous  puncture  externally.  Maxillre  slender,  hooked  at  tip,  ciliate 
or  spinous  within,  the  outer  lobe  usually  slender,  biarticulate  (except  Callistufi), 
the  palpi  moderately  long,  the  terminal  joint  variable  in  form.  Mentum  broad, 
usually  emarginate  ai^d  toothed,  sometimes  feebly  bisinuate  in  front  (Evoleyies) 
or  even  almost  truncate  (Brachylobusi,  the  basal  suture  always  distinct,  ligula 
moderately  prominent,  usually  free  at  tip  and  bisetose,  the  paraglossse  membranous 
more  or  less  free  at  tip,  longer  or  not  than  the  ligula,  elongate  and  slender  in 
AnomoglosKus  and  ciliate  within,  palpi  moderate  in  length,  the  terminal  joint 
variable,  the  penultimate  bi-  or  plurisetose  or  even  without  setse.  Thorax  variable 
in  form,  the  setfe  of  the  margin  either  slender  or  entirely  wanting.  Body  not 
pedunculate,  scutelhim  distinct.  Elytra  margined  at  base,  sides  narrowly  intiexed, 
margin  interrupted  posteriorly  and  with  a  distinct  internal  plica,  surface  striate, 
without  dorsal  punctures.  Prosteruum  prominent  at  tip  but  not  prolonged.  Meso- 
sternum  rather  widely  separating  the  coxre,  grooved  in  front,  the  epimera  narrow. 
Metasternal  epimera  distinct,  posterior  coxse  contiguous.  Legs  moderate,  middle 
and  posterior  tibise  finely  spinulose  externally,  the  anterior  moderately  broad, 
a  few  stout  spines  at  the  outer  apical  angle,,  within  deeply  emarginate  the  inner 
spur  at  the  angle  of  the  emargination.     Tarsi  slender,  claws  simple. 

The  males  have  three  or  four  joints  of  the  anterior  tarsi  dilated  and  densely 
spongy  beneath. 

After  the  very  able  papers  by  Baron  Chaudoir  on  this  tribe  (Bull. 
Mosc.  1856  and  1857  ;  Ann.  Mus.  Civ.  di  Genova  viii,  1876',  it  seems 
entirely  unnecessary  to  enter  into  any  further  discussion  of  the  subject. 
I  can  not  realize  the  necessity  for  separating  CaUistus  as  a  distinct  tribe 
but  his  conclusion  concerning  Atranus  seems  to  me  just.  CaUistus  affords 
one  of  the  rare  instances  in  Carabidae  in  which  the  outer  maxillary  lobe 
is  formed  of  one  piece  by  the  complete  fusion  of  the  two  which  usually 
exist,  without  leaving  any  trace  of  suture  as  is  the  case  in  Ameriztis. 
The  mentum  of  BracJiylohus  (117),  is  the  most  complete  illustration  of 


172  GEO.    H.    HORN,    M.  D. 

the  obliteration  of  the  usual  emargination  known  to .  me,  although  the 
epilobal  piece  is  very  distinctly  present. 

The  present  tribe  is  divided  into  two  groups : 

Eighth  stria  of  the  elytra  with  its  oeellate  punctures  distant  from  the  margin, 
the  ninth  stria  very  distinct.     Eyes  regular  in  outline  not  truncate  behind. 

Chl^nii. 

Eighth    stria    very    close    to   the    margin,    the    ninth    indistinct.      Eyes   truncate 
behind Codes. 

In  the  first  group  three  genera  occur  in  our  fauna : 

Mentuni  witli  distinct  lateral  lobes. 

Toothed  in  tlie  bottom  of  the  emargination ChlseiiillS. 

Not  toothed AiioiiiogloMsus. 

Mentum  truncate  in  front ; Bracliylobus'. 

In  the  second  group  the  genera  may  still  be  the  subject  of  discussion, 
those  represented  in  our  fauna  are  recognized  by  the  following  characters  ; 

All  the  tarsi  pubescent  beneath. 

Anterior  tarsi  %  with  four  joints  not  widely  dilated.     Clypeus  with  a  setigerous 

puncture  each  side.     Labrum  6-setose L<aclin<»crepis. 

Posterior  tarsi  not  pubescent  beneath. 

Anterior   tarsi    %    with    four  joints   dilated,    the    first   three    spongy    beneath. 
Clypeus  without  setigerous   punctures.     Labrum  with   six  setse,  the  four 

central  small  and  close,  the  outer  large  and  erect Anatrichis. 

Anterior  tarsi  '^  with  three  joints  dilated  and  spongy. 

Second  joint  of  labial  palpi  without  setfe  in  front Oodes. 

Second  joint  of  labial  palpi  bisetose  in  front Evoleiies. 

EvoLENES  has  the  antennae  somewhat  flattened.  The  clypeus  has 
a  large  setigerous  puncture  each  side  and  the  labrum  six.  It  is  the 
only  genus  in  the  group  in  which  the  second  joint  of  the  labial  palpi 
has  the  setae  so  universally  observed  in  the  Carabidae. 

OoDES  as  above  intended  contains  Oodes,  Stenous  and  Crossocrepis 
of  Chaudoir.  The  latter  is  based  on  the  supposed  conformation  of  the 
ligula  which  my  own  dissections  prove  not  to  exist.  The  other  two 
genera  are  separated  by  the  mode  of  dilatation  of  the  anterior  tarsi. 
In  Oodes  proper  the  clypeus  has  a  setigerous  puncture  each  side  and 
the  labrum  six  in  front,  in  the  other  two  there  are  no  clypeal  punctures 
and  three  only  on  the  labrum. 

The  inconstancy  of  the  setigerous  punctures  in  the  Oodes  is  re- 
markable, the  only  one  absolutely  present  in  all  is  the  one  over  the  eye 
The  entire  absence  of  these  punctures  from  the  side  of  the  thorax 
would  be  an  excellent  means  of  separating  the  Chlaenii  and  Oodes,  were 
it  not  that  even  in  Chlfenius  these  punctures  although  constantly  present 
are  often  lost  in  the  general  punctuation  and  the  seta  is  small  and  hair- 
like and  not  very  evident  except  in  the  glabrous  species. 


AMERICAN    COLEOPTERA.  173 

It  may  be  observed  in  Chlaenius  that  those  species  in  which  the  males 
have  not  the  pubescent  space  near  the  tip  of  the  middle  tibiae,  that  is, 
those  of  my  division  A  (Trans.  Am.  Ent.  Soc.  v,  1876,  p.  257),  are 
without  setae  on  the  second  joint  of  the  labial  palpi,  while  division  B 
(and  Anomoglossus  with  its  long  second  joint)  is  plurisetose. 

Tribe  XLVL— Zabrini. 

AntennfB  filiform,  arising  beneath  a  slight  frontal  ridge,  the  three  basal  joints 
glabrous.  Head  short,  without  distinct  neek,  one  supra-orbital  puncture.  Clypeus 
very  slightly  prolonged,  a  puncture  in  each  anterior  angle.  Eyes  oval,  relatively 
small,  not  more  convex  than  the  sides  of  the  head,  distant  beneath  from  the 
mouth.  Labrum  feebly  emarginate  and  plurisetose  in  front.  Mandibles  stout, 
arcuate,  more'  or  less  obliquely  furrowed  above,  without  setigerous  puncture 
externally  and  feebly  bidentate  on  inner  margin.  Maxillae  strongly  hooked  at 
tip  with  stiff"  bristles  within,  outer  lobe  biarticulate,  palpi  stout,  third  joint  longest, 
fourth  oval.  Mentum  broad  deeply  emarginate,  variabh'  toothed,  the  ligula 
moderately  prominent,  apex  free,  truncate  or  bisinuate  and  bisetose,  the  para- 
glossse  obtuse  and  not  longer  than  it,  the  palpi  moderate,  the  second  joint  longer, 
plurisetose  in  front,  last  joint  somewhat  oval,  shorter  than  the  preceding.  Thorax 
broad,  as  wide  as  the  elytra,  a  setigerous  puncture  at  the  side  but  none  at  the 
hind  angle.  Body  not  pedunculate,  scutelluin  distinc-t.  Elytra  narrowly  inflexed 
at  the  sides,  the  margin  interrupted  posteriorly  and  with  a  well  marked  internal 
plica.  Prosternum  not  prolonged.  Mesosternum  rather  wide  between  the  coxse 
and  broadly  concave,  the  epimera  narrow.  Metasternal  epimera  distinct,  posterior 
coxae  contiguous.  Legs  moderate,  middle  and  posterior  tibiae  gradually  broader  to 
tip,  spinulo3e  externally,  the  anterior  of  elongate-triangular  form,  spinulose  at 
outer  api(!al  angle,  the  inner  side  obliquely  grooved,  the  inner  sjjur  not  remote 
from  tip,  the  terminal  spur  short,  broad,  laminate  at  the  sides  and  suddenly 
narrower  at  tip.     Tarsi  filiform,  fourtii  joint  simple. 

The  males  have  the  first  three  joints  of  the  anterior  tarsi  rather  widely  dilated 
and  biseriately  squamulose  beneath. 

In  some  species  the  males  have  tlic  apices  of  the  middle  and  pos- 
terior tibiae  prolonged  on  the  inner  side  in  a  dentiform  process.  By  all 
European  authorities  the  anterior  tibiae  are  said  to  have  two  spurs  at 
the  apex  and  one  above  the  emargination  in  the  usual  position.  This 
statement  of  the  facts  of  the  case  seems  to  me  a  very  loose  expression. 
All  Carabidae  have  at  the  tips  of  the  tibiae  two  spurs  which  are  in  all 
cases  articulated  appendages  of  the  tibiae.  These  in  whatevei-  language 
used  are  called  by  the  equivalent  of  our  word  "spur."  That  which 
makes  the  so-called  smaller  terminal  spur  is  merely  a  dentiform  pro- 
longation of  the  inner  apical  angle  of  the  tibia  which  is  in  all  respects 
the  homologue  of  the  apical  tooth  of  the  middle  and  posterior  tibia&  of 
certain  males.  I  am  not  aware  of  any  coleopterous  insect  having  more 
than  two  true  tibial  spurs  and  I  therefore  venture  to  object  to  any  form 
of  exprcsNion  conveying  a  fals3  idea. 

It  will  also  be  observed  that  the  anterior  tibia;  are  far  less  emarginate

than  usual  in  the  present  series  of  Carabidse,  and  the  structure  of  the 
inner  side  may  be  compared  rather  to  the  deep  oblique  groove  already 
mentioned  in  some  of  the  earlier  tribes. 

The  ophiion  expressed  by  Zimmerman  that  Zahrus  should  constitute 
a  special  tribe  seems  to  me  far  more  nearly  correct,  than  that  expressed 
by  Lacordaire,  Schaum  and  others  in  placing  it  in  the  Pterostichini. 
It  is  however,  as  remarked  by  Bedel,  an  intermediate  tribe  between  the 
Pterostichini  and  Harpalini,  with  strongly  marked  characters  of  each 
tribe  equally  present  and  yet  abundantly  distinct  from  either  by  the 
structure  of  the  anterior  tibiae.  The  head  and  thorax  are  decidedly 
Harpalide  in  structure  while  the  elytra  and  anterior  tarsi  are  Pterosti- 
chide.  The  mouth  parts  do  not  exhibit  any  more  decided  relation  with 
the  one  tribe  than  the  other. 

Zahrus  belongs  to  the  Circum-iNIediterranean  fauna  extending  to  the 
Caspian  Sea. 

Tribe  XLVII. -Harpalini. 

Antennre  usiuilly  slender  arising  under  a  slight  frontal  ridge,  the  two  basal 
joints  glabrous,  sometimes  also  the  greater  part  of  the  third.  Head  often  large, 
usually  moderate,  not  narrowed  to  a  neck,  with  one  supra-orbital  seta.  Eyes 
usually  moderate  in  size,  never  very  convex,  not  distant  beneath  from  the  mouth, 
sometimes  however  small  and  distant.  Clypeus  slightly  prolonged  between  the 
mandibles,  with  one  or  two  setigerous  punctures  near  the  apical  margin.  Labrum 
moderately  prominent,  truncate  or  emarginate,  plurisetose  in  front.  Mandibles 
stout,  rarely  (  Glyptus)  prominent,  acute  at  tip  and  without  setigerous  puncture 
externally.  Maxillae  hooked  at  tip  ^except  in  Gli/ptus),  although  rather  feebly  in 
some  genera  (ArLiitus),  the  inner  margin  ciliate,  the  outer  lobe  usually  slender, 
as  long  as  the  inner  lobe  but  shorter  in  Glyptus.  biarticulate,  the  terminal  joint 
often  longer  than  the  first,  the  palpi  moderate,  the  terminal  joint  slightly  oval  or 
subcylindrieal,  sometimes  slightly  pilose.  Mentum  broad,  emarginate,  with  or 
without  a  median  tooth  which  is  sometimes  as  long  as  the  lobes  [Arifstvts)  ;  ligula 
prominent,  variable  in  form,  the  tip  free  (usually  bisetose)  and  in  most  cases 
dilated,  the  paraglossse  variable  in  form  always  as  long  as,  frequently  longer  than 
the  ligula  and  very  often  ciliate  at  tip,  the  palpi  moderate  in  length,  the  terminal 
joint  never  longer  and  very  rarely  equal  to  the  preceding  which  is  plurisetose 
except  in  Glyptus  where  there  are  no  setse.  Thorax  variable  in  form,  with  a 
lateral  seta,  but  none  in  the  hind  angles.  Body  sometimes  subpedunculate, 
scutellum  distinct.  Elytra  usually  margined  at  base,  sides  narrowly  inflexed, 
the  margin  variable  but  never  with  an  internal  plica,  surface  striate,  often  densely 
punctured,  either  pubescent  or  glabrous,  with  or  without  dorsal  punctures.  Pro- 
sternum  not  prolonged.  Mesosternum  separating  the  coxse,  the  epimera  very  nar- 
row. Metasternal  epimera  distinct,  the  posterior  coxse  contiguous.  Legs  variable, 
often  stout  and  fossorial.  The  middle  and  posterior  tibiaj  otten  spinulose  or  even 
serrulate  externally,  the  anterior  with  the  outer  apical  angle  spinous  or  prolonged 
obtusely.     The  tarsi  variable  in  structure. 

Sexual  characters  variable.

trivial  characters,  this  tribe  has  become  the  most  difficuh  to  study  of 
any  in  the  Carabidse  excepting  possibly  the  Lebiini.  Characters  drawn 
from  the  ligula  and  paraglossae  have  here  as  in  the  Lebiini  been  pushed 
to  an  extreme,  and  a  study  of  them  from  my  own  dissections  proves 
that  in  both  tribes  they  have  not  the  great  value  which  has  been  assigned 
to  them.  It  seems  to  me  better  to  reject  them  almost  entirely,  certainly 
as  a  means  of  separating  tribes  or  groups  and  possibly  even  genera. 

The  tribe  Harpalini  as  here  intended  contains  the  Ditomides  of 
Lacordaire,  (G-enera  i,  p.  165),  the  Cratocerides,  Anisodactylides  and 
Harpalides  of  the  same  author,  and  I  add  also  Glt/ptus. 

From  the  Ditomides  all  authors  who  have  studied  it  agree  that 
Apntomui^  should  be  removed.  From  the  Cratocerides  Cydosonms 
should  be  removed  as  suggested  by  Schaum  and  Chaudoir  and  placed, 
as  indicated  by  the  latter  in  the  Lebiini,  ^Bull.  Mosc.  1872*.  ISomo- 
platus  and  Macracnnthus  are  allied  to  Masoreus,  (Schaum,  Berl.  Zeits. 
1800,  p.  178;  Chaudoir,  Bull.  Mosc.  1870,  Monog.  des  Masoreides\ 
After  all  this  dismemberment  Chaudoir  forms  of  Crafocerus,  Bruchidio 
and  Basolia  a  special  group,  "  plus  ou  moihs  voisin  des  Drimosfoma:' 
Among  the  Anisodactylides  Orthogonius  and  Mlgodops  should  be  re- 
moved, the  former  constituting  a  distinct  tribe  near  the  Lebiini,  the 
latter  being  a  member  of  the  first  sub-family.  The  Harpalides  does  not 
appear  to  contain  any  offending  material. 

To  the  tribe  must  hi  added  Fo/pochi/u  (for  wliicii  however,  Lacor- 
daire uses  a  synonym  Melunotna  Dej.  ,  and  Stenomorphus,  the  affinities 
of  the  latter  having  been  properly  recognized  by  Schaum. 

From  my  own  study  I  am  convinced  that  Gtyptus  can  find  no  better 
place  than  as  a  group  in  the  present  tribe.  The  genus  was  described 
by  Brulle  who  placed  it  in  the  Ditomides,  a  position  which  does  not  to 
me  seem  so  erroneous  as  Lacordaire  intimates.  The  latter  author  places 
it  in  the  most  heterogeneous  of  his  tribes  (^Stomides)  near  Idiomorplius 
to  which  it  seems  not  to  be  greatly  allied,  although  Schaum  (Berl.  Zeits. 
1800,  p.  178),  says  that  these  two  genera  are  Orthogoniens,  while  Chau- 
doir properly  omits  them  from  his  monograph  of  that  group,  (Annales 
Belg.  xiv,  1872).  Idiomorphus  is  known  to  me  by  the  figure  which 
Lacordaire  gives  and  I  can  therefore  express  no  opinion. 

The  characters  of  Glyptus  are  decidedly  those  oi'  a  Har[)alide  and 
I  think  it  can  very  properly  be  compared  with  our  own  Geopinua. 
In  both  genera  it  will  be  observed  that  the  antenmii  are  rather  short 
and  quite  distinctly  geniculate,  the  third  joint  feebly  pubescent  at  tip 
in  Geopinus  and  almost  entirely  glabrous  in  Glypfus.     In  both  genera 


17()  GEO.    H.    HORN,    M.  D. 

the  following  joints  are  pubescent  at  the  edges  only  the  middle  being 
glabrous.  The  legs  are  similar,  the  anterior  tibiae  especially,  so.  The 
mouth  parts  are  also  of  the  same  general  type  observed  throughout 
the  Harpalini,  especially  Nothopus  and  Piosomu.  It  will  be  observed 
however  that  the  maxillae  are  not  hooked  at  tip  although  acute,  and  the 
outer  lobe  considerably  shorter  than  the  inner,  a  character  which  I  have 
not  elsewhere  found  in  the  Carabidc«.  The  tarsi  are  also  truly  Harpalide, 
the  male  having  four  joints  of  the  anterior  and  middle  pairs  dilated  and 
biseriately  squamulose.  Finally,  the  position  of  the  tactile  setas  of  the 
head  and  thorax  show  that  Glyptus  must  be  placed  in  the  present  series. 
The  tribe  Harpalini  may  be  divided  primarily  by  the  tarsal  vestiture 
of  the  male  into  three  series  one  of  which  may  be  again  divided,  the 
four  groups  thus  formed  may  be  characterized  in  the  following  manner : 

Anterior  tarsi  of  male  pilose  or  spinous  beneath,  usually  feebly  sometimes  not  at 

all  dilated Dapti. 

Anterior  tarsi  of  male  dilated  and  biseriately  squamulose. 

MaxillfB  not  hooked  at  tip,  the  outer  lobe  much  shorter  than  the  inner,  penulti- 
mate joint  of  labial  palpi  not  setose,  labrum  very  short Glvpti. 

Maxillae  hooked  at  tip,  the  outer  lobe  equal  to  or  longer  than  the  inner,  the 

penultimate  joint  of  labial  palpi  plurisetose,  labrum  normal Habpali. 

Anterior  tarsi  of  male  densely  spongy  pubescent  beneath Anisgdactyli. 

The  tarsal  vestiture  above  outlined  appears  to  be  the  only  means  yet 
devised  for  the  division  of  the  tribe.  It  is  not  however  without  ex- 
ceptions as  certain  Dapti,  Geopinus  for  example  have  a  few  squamules 
on  the  under  side  of  the  anterior  tarsi,  and  certain  Acinopus  have  the 
anterior  tarsi  feebly  dilated  and  the  squamules  rudimentar3^ 

Group  Dapti. 

The  genera  of  this  group  present  certain  special  characters  which 
require  passing  mention.  In  the  majority  of  the  genera  the  eyes  are 
small  and  beneath  widely  separated  from  the  buccal  fissure.  In  Daptus, 
Polpochila,  Acjonoderus  and  Pugonodaptvs  the  eyes  are  normal  in  form 
and  close  to  the  mouth  beneath.  The  mandibles  of  Geopinus,  Daptus 
and  Pogonodaptns  are  normally  decussating,  the  left  overlapping  the 
right  with  its  tip  somewhat  chisel-shaped  and  deeply  strigose  in  the 
first  two  genera,  acute  and  not  strigose  in  the  third.  In  all  the  other 
genera  mentioned  below  the  light  mandible  appears  to  be  shorter  than 
the  left  and  is  capable  of  being  drawn  more  within  the  mouth,  its 
chisel-shaped  tip  passing  along  the  obtuse  inner  edge  of  the  left  re- 
minding me  of  the  manner  of  the  articulation  of  the  lower  mandible  of 
the  Parrot  on  the  upper  or  like  the  incisor  teeth  of  a  Kodent. 

Daptus  has  also  a  small  triangular  plate  over  the  insertion  of  the 
antennjxi  as  observed  in  Ditomus. 


AMERICAN    COLEOPTERA.  I"*"? 

On  examiniug  the  under  side  of  the  head  the  usual  setaB  may  be  seen 
at  the  middle  of  the  mentum,  one  on  each  side  and  behind  the  base  of 
the  mentum  tooth  and  which  may  for  convenience  be  called  post-dental 
set?e.  In  all  the  genera  with  one  exception  there  will  also  be  seen  two 
setigerous  punctures  at  the  side  of  the  submentum  immediately  behind 
the°angle  of  the  mentum.  In  Polpochila  and  Agonoderm  the  two  setae 
are  quke  conspicuous,  the  inner  one  of  each  pair,  however,  larger  than 
the  outer,  but  in  the  other  genera  the  outer  seta  gradually  becomes 
more  and  more  feeble  so  that  it  finally  disappears  or  can  only  with  great 
difficulty  be  found.  In  Geopinus  however  there  is  but  one  seta  on  each 
side  and  this  is  situated  in  the  posterior  angle  of  the  mentum  itself. 

The  anterior  tibiae  are  usually  gradually  dilated  to  apex  and  spinous 
at  tip  externally,  but  in  Geopinus  the  outer  angle  is  expanded  in  a  plate, 
spinulose  on  its  edge  resembling  in  general  form  that  of  Glyptus.  In 
Nothopus  the  outer  angle  is  more  narrowly  prolonged  and  rather  deeply 
sinuate  above  the  tooth.  Daptus  has  a  thicker  anterior  tibia  the  outer 
angle  rounded,  the  posterior  face  rather  closely  beset  with  spinules  as 
in  Phaleria,  the  fossorial  habits  of  which  it  imitates. 

The  following  table  will  enable  our  genera  to  be  recognized : 

Mandibles  prominent,  decussating.     Body  subpedunculate. 

Mandibles  deeply  stri.i;ose  at  tip.     Anterior  tibife  decidedly  fossorial. 

Eyes  small.     Mentum  with  a  seta  at  hind  angles CJeO|Uiius. 

Eyes  large.     Setse  at  sides  of  submentum Daptus. 

Mandibles  acute  at  tip  not  strigose.    Anterior  tibia  not  foss.-rial.    No  seutellar  stna. 

Head  with  deep  arcuate  impression  each  side Pogouotlaptus. 

Mandibles  not  prominent,  at  most  feebly  decussating.     Body  not  peduncvilate. 

Outer  apical  angle  of  anterior  tibite  prolonged Motliopus. 

Outer  apical  angle  of  tibise  not  prolonged. 
Mentum  toothed. 
Apical  angles  of  joints  1—?.  of  anterior  tarsi  prolonged  in  spines.     Eyes 

large.     Hind  angles  of  thorax  obtuse  or  rounded Polpochila. 

Apical  angles  of  joints  of  anterior  tarsi  not  prolonged.     Eyes  small.     Hmd 

angles  of  thorax  sharply  rectangular fralacaiiUlUS. 

Mentum  not  toothed. 

Posterior  tarsi  with  the  first  joint  a  little  longer  than  the  second,  outer 
edge  of  middle  tibire  rather  flat  and  with  a  double  row  of  spinules 
closely  placed. 
Eyes  relatively  small,  distant  beneath  from  the  mouth ;  elytra  with 

numerous  dorsal  punctures Fiosoma. 

Eyes  relatively  large,  very  narrowly  separated  from  the  mouth ;  elytra

178  GEO.    H.    HORN,    M.  D. 

The  sexual  characters  are  not  very  well  marked.  The  males  have  four 
joints  of  the  anterior  tarsi  feebly  dilated  (two  in  Folpochild)  and  rarely 
{Discoderus)  with  a  few  squamules  beneath.  The  latter  genus  has  the 
middle  tibiae  distinctly  arcuate  and  serrate  within.  In  Cratacnnthus  the 
right  mandible  of  the  male  has  the  basal  portion  which  borders  the 
clypeus  more  elevated,  while  the  upper  edge  in  front  of  this  is  much 
depressed,  a  similar  structure  is  observed  in  Aciaopus. 

The  Ditomides  of  Lacordaire  should  not  in  my  opinion  be  widely 
separated  from  the  present  group.  The  only  character  in  which  they 
differ  is  in  the  apex  of  the  ligula  being  plurisetose.  Their  punctured 
surface  gives  them  a  somewhat  different  aspect  but  this  has  a  parallel  in 
Dichirus  in  the  Anisodactyli  and  Ophonus  in  Harpali. 

To  this  group  belong  also  Cratognathus  placed  by  Lacordaire  in  the 
Anisodactyli  and  Puramecus  of  his  Harpali. 

I  have  introduced  Daptus  in  the  above  table  for  convenience  of 
comparison,  it  does  not  occur  in  our  fauna.  The  genera  above  men- 
tioned differ  to  a  greater  or  less  extent  in  the  form  of  the  ligula  and 
paragiossae  as  well  as  in  the  extent  of  pilosity  of  the  tei'minal  joint  of 
the  palpi.  Agoiwderun  and  Pogonodaptua  are  the  only  genera  in  which 
I  have  observed  the  penultimate  joint  of  the  labial  palpi  to  be  bisetose. 
Nothopun  and  Piosoma  have  the  ligula  quadrisetose .  and  the  paraglossfe 
ciliate  externally  at  tip,  the  upper  surface  is  also  sparsely  setose  in  these 
genera.  In  Oratacanthus  the  paraglossas  are  very  broad  and  lie  behind 
the  ligula,  so  that  when  viewed  from  the  front  the  entire  ligula  has  very 
much  the  appearance  of  that  of  a  Lebiide. 

The  name  Pogonodaptus  is  proposed  for  a  small  species  resembling 
Daptus  arid  somewhat  also  Pogonus  (Pogonistes),  which  has  the  fol- 
lowing characters. 

POGONODAPTUS  n.  g. 

Head  moderately  large,  horizoutal,  not  narrowed  behind  the  eyes  to  a  neck. 
Eyes  moderately  large  and  prominent,  narrowly  separated  from  the  mouth. 
AntennsB  arising  under  a  slight  frontal  ridge,  the  second  joint  a  little  shorter 
than  the  third.  Clypeus  slightly  prolonged  between  the  mandibles,  narrow, 
emarginate  in  front,  a  seta  in  each  angle.  Labrum  broadly  emarginate,  sexsetose. 
Mandibles  prominent,  decussating,  feebly  arcuate,  tips  acute,  a  slight  tooth  at  the 
middle  of  the  right.  Mentum  broad,  feebly  emarginate,  a  short  broad  tooth  at 
middle.  Ligula  small,  free  and  bisetose  Mt  tip  and  narrowed,  the  paraglossse 
falciform  a  little  longer  than  it,  the  palpi  slender,  penultimate  joint  a  little  longer 
than  the  last  and  bisetose.  Maxillary  palpi  moderate  in  length,  the  terminal  joint 
slender,  slightly  fusiform,  a  little  longer  than  the  preceding.  Thorax  transverse, 
narrowed  behind,  posterior  angles  distinct.  Body  pedunculate.  Elytra  oblong, 
parallel,  very  slightly  sinuate  near  the  tip,  surface  striate,  without  scutellar  stria, 
a  dorsal  puncture  on  the  third  interval  near  the  second   stria.     Anterior  tibire

not  fossorial,  the  outer  edge  spinous,  middle  tibise  on  the  outer  edge  biseriately 
spinulose,  the  posterior  more  finely  so.  Posterior  tarsi  slender  with  joints  1 — 4 
gradually  decreasing  in  length. 

This  genus  is  known  from  any  in  the  tribe  by  its  prominent 
and  smooth  mandibles,  the  non-fossorial  tibiae,  the  absence  of  scutel- 
lar  stria,  while  the  form  of  the  ligula  and  paraglossse  distinguishes 
it  from  Daptus. 

P.  piceus  n.  sp. — Moderately  elongate,  parallel,  piceous,  shining,  legs  pale 
testaceous.  Head  smooth,  a  moderately  deep  arcuate  impression  each  side.  An- 
tennfe  piceous,  two  basal  joints  pale.  Tliorax  transversely  cordate,  sides  arcuate 
and  narrowing  posteriorly,  hind  angles  small  moderately  prominent,  base  arcuate, 
^pex  very  feebly  emarginate,  disc  moderately  convex,  median  line  finely  impressed, 
a  short  intra-angular  basal  impression,  surface  jmooth,  shining.  Elytra  oblong, 
parallel,  humeri  obtuse,  surface  striate,  the  striae,  entire  and  not  punctate,  no 
scutellar  stria,  intervals  flat,  smooth.  Body  beneath  piceous,  shining,  tip  of 
abdomen  paler,  surface  smooth,  impunctate.    Length  .24  inch  ;  6  mm. 

I  have  but  one  specimen,  a  female,  from  Texas,  given  me  by  Mr.  A. 
S.  Fuller. 

Group  Glypti. 

I  have  already  given  the  reasons  not  only  for  placing  Glyptus  in 
the  present  tribe  but  also  for  considering  it  a  group  apart.  With  the 
exception  of  the  characters  which  mark  it  as  a  special  type  in  the  tribe 
it  seems  to  bear  the  same  relation  to  the  Harpali  which  follow,  that 
Geopinus  does  to  other  Dapti.  G.  scu/pfi/is  Br.,  is  figured  by  Lacor- 
daire  (Genera,  Atlas,  pi.  10,  fig.  3),  in  such  a  position  on  the  plate  as 
to  make  its  comparison  with  the  better  figure  of  Geopinus  quite  easy. 
The  species  above  cited  occurs  in  western  part  of  Africa  and  lives 
in  the  nests  of  White  x\nts.  A  second  species  has  been  described  by 
Chaudoir  from  Egyj)t. 

Group  Harpali. 

It  is  extremely  difficult  to  draw  the  line  with  accuracy  between  this 
group  and  the  Dapti,  and  I  am  convinced  that  other  characters  will  be 
found  which  will  separate  the  genera  but  which  will  not  allow  the  groups 
to  remain  as  at  present  con.stituted. 

Not  having  access  to  as  much  exotic  material  as  I  desire  I  cannot 
venture  on  a  discussion  of  the  genera  which  should  be  here  included, 
and  will  confine  my  remarks  to  those  of  our  own  fauna. 

At  the  time  of  the  publication  of  the  "  Classification  of  the  Coleoptera 
of  North  America,"  by  Dr.  LeConte,  six  genera  were  placed  in  the 
Harpali.  Since  then  two  have  been  suppressed  Philodes  (=  Stenolophus) 
and  Gynandrotarsus  (r=  Anl&odactyhis).  It  is  however  necessary  to 
add  Stenomorphus,  and  Selenopliorua  should  be  rehabilitated  as  sug-

180  GEO.    H.    HORN,    M.  D. 

I  have  already  referred  to  the  fact  that  in  by  far  the  larger  number 
of  genera  of  Harpalini  the  labial  palpi  have  the  last  joint  shorter  than 
the  preceding,  while  the  latter  is  then  more  than  bi-setose  except  in 
Glyptus  which  seems  to  have  lost  the  setse  entirely.  In  the  Dapti 
Agonoderus  has  been  referred  to  as  one  of  the  rare  exceptions  to  the 
rule  and  the  terminal  joint  is  as  long  or  longer  than  the  preceding  and 
the  latter  simply  bisetose  in  front.  The  presence  of  a  few  hairs  more 
or  less  may  seem  a  very  trivial  character,  but  when  this  is  always 
associated  with  another  important  structural  character  and  is  moreover 
absolutely  constant,  it  assumes  an  importance  far  greater  than  the  slight 
ligular  differences  which  are  apt  to  be  described  and  even  figured  differ-* 
ently  by  two  equally  competent  students. 

In  order  that  the  argument  may  be  followed  more  easily  it  will  be 
better  to  discuss  the  genera  separately,  and  will  call  the  labial  palpi 
normal  when  the  last  joint  is  short  and  the  preceding  plurisetose. 

Stenomorphus. — Labial  palpi  normal.  Anterior  tarsi  of  male  moder- 
ately dilated,  the  first  joint  nearly  equal  to  the  three  following  and  not 
squamulose  beneath,  the  next  three  biseriately  squamulose,  the  fourth 
transverse  feebly  emarginate.  Anterior  tibiae  ciliate  within.  Middle 
femur  with  a  triaugular  dilatation  of  the  anterior  condyle  at  the  knee, 
the  middle  tibia  slightly  arcuate,  middle  tarsus  not  dilated.  Mandibles 
chisel-shaped  at  tip. 

The  female  has  the  first  joint  of  the  anterior  tarsi  rather  broadly 
dilated  and  not  spongy  nor  papillose,  the  tibia  is  not  ciliate  within.  The 
middle  femur  is  not  toothed  at  apex,  the  tibiaj  slightly  curved. 

It  will  be  seen  by  the  above  characters  that  the  genus  should  not  be 
placed  with  Anisodactylus  as  stated  by  Schaum,  much  less  with  the 
Pogonini  as  Lacordaire  has  done. 

GrYNANDROPUS. — The  labial  palpi  are  normal.  The  anterior  tarsi 
are  moderately  dilated  in  the  male,  the  first  four  joints  biseriately 
scjuamulose,  the  first  about  as  long  as  the  next  two.  The  female  is 
as  in  Stenomorphus. 

This  genus  makes  a  nearer  approach  to  the  true  Harpali  than  the 
]»recediiig. 

TRioiiopsELAPHrs. — Palpi  unknown,  probably  normal.  The  anterior 
tarsi  of  male  with  four  joints  dilated  and  squanudose  beneath,  joints  1  —  4 
decreasing  gradually  in  length,  the  fourth  emarginate.  Posterior  tibife 
arcuate,  inner  edge  crenulate  and  ciliate.  In  the  female  the  first  four 
joints  are  dilated,  the  first  strongly,  much  longer  than  any  of  the  fol- 
lowing joints,  not  squamulose  or  spongy  beneath. 


AMERICAN    COLEOPTERA.  181 

This  genus  occurs  in  Brazil  and  is  introduced  here  as  it  shows  some 
relation  with  Discoderus  of  the  preceding  group  while  plainly  a  member 
of  the  present. 

AciNOPUS. — Palpi  normal.  In  both  sexes  the  anterior  and  middle 
tarsi  are  dilated,  and  in  the  males  biseriately  squamulose  beneath. 

In  this  genus  was  first  observed  the  difference  between  the  right 
and  left  mandible  of  the  male  to  which  I  have  called  attention  in 
Cratacanthus.  It  occurs  in  Europe  and  is  mentioned  as  one  of  the 
links  between  the  present  group  and  the  Dapti. 

Harpalus. — Palpi  normal.  In  the  male  the  anterior  and  middle 
tarsi  are  dilated  and  biseriately  squamulose  beneath,  the  fourth  joint 
emargiuate  or  subbilobed.  In  the  female  the  tarsi  are  slender.  The 
posterior  tarsi  have  the  first  joint  never  longer  than  the  next  two.  The 
elytra  have  one  dorsal  puncture  or  none.     Paraglossae  ciliate  at  tip. 

Selexophorus. — Palpi  normal.  Sexual  characters  of //^»r/;^</i<.s.  First 
joint  of  hind  tarsus  e(puil  to  the  next  three.  Elytra  with  three  rows  of 
dorsal  punctures.      Paraglossae  with  at  most  one  cilia  at  the  sides. 

A  review  of  the  species  of  our  fauna  will  be  found  in  Proc.  Amer. 
Philos.  8oc.  1880,  p.  178. 

Stenolophus. — Palpi  abnormal,  the  last  joint  of  the  labial  oval, 
acuminate,  the  penultimate  bisetpse  in  front.  Anterior  tarsi  of  male 
with  four  joints  dilated  and  biseriately  S(juamulose  beneath,  the  ftmrth 
joint  deeply  bilobed,  middle  tarsi  moderately  dilated  and  squamulose. 
First  joint  of  hind  tarsi  about  as  long  as  the  two  following  together. 
The  females  have  the  tarsi  slender,  the  fourth  joint  of  the  anterior 
pair  emargiuate. 

In  the  above  genus  will  be  contained  those  species  in  our  fauna 
included  by  Dr.  LeConte  in  his  divisions  A,  B,  D,  (Proc.  Acad.  1868, 
p.  ?)~(i).  It  will  be  observed  that  the  last  joint  of  the  labial  palpi  is 
more  slender  and  less  oval  than  in  the  species  of  his  group  C.  I  have 
also  observed  that  in  some  species  this  same  joint  is  impressed  or  concave 
beneath  in  the  male,  (/imbttlis,f(tli(jinosus,  conjunctus,  anceps,  cincticolh's, 
Jiavlpea  and  ochropezus),  in  others  it  is  entirely  simple,  {ccnbonarhts, 
plebejus  and  tfissimi/is).  Several  have  not  been  examined  as  males  are 
not  at  hand.  In  souie  species  also  the  hind  tarsi  have  a  tine  carina  on 
the  outer  side  of  the  first  three  joints.  The  middle  tarsi  are  sometimes 
sulcate  as  in  P/afi/mis.  I  mention  these  observations  that  they  may  be 
made  use  of  by  future  students  of  the  genus. 

AcuPALPUS. — Palpi  abnormal,  the  terminal  joint  of  the  labial  rather 
stoutly  oval  but  slender  at  tip.  the  penultimate  bisetose  in  front.      Ante-

rior  tarsi  of  male  moderately  dilated,  biseriately  squamulose  beneath,  the 
fourth  joint  feebly  emarginate.  Middle  tarsi  feebly  dilated  but  distinctly 
squamulose.  The  first  joint  of  posterior  tarsi  is  distinctly  shorter  than 
the  next  two'  together.     The  females  have  slender  tarsi. 

Here  also  may  be  observed  the  depression  in  the  last  joint  of  the 
labial  palpi  of  the  male.  I  was  at  first  inclined  to  believe  that  this 
might  be  a  post-mortem  character  the  result  of  contraction,  but  its 
occurrence  in  males  only  seems  to  indicate  that  it  is  probably  a  character 
found  also  in  life,  of  a  sexual  import. 

In  this  genus  are  contained  those  species  in  section  C,  (loc.  cit.  p.  377), 
hydropicus,  carus,  lonfjulus,  JiitvUimhus  and  rectangulus.  Acupalpus 
seems  fully  as  worthy  of  being  maintained  as  many  of  the  genera  of  the 
present  tribe,  if  we  reject  its  characters  as  invalid  for  generic  separation 
it  will  be  almost  impossible  to  separate  genera  in  the  group  Harpali. 

Bradycellus. — 'As  far  as  the  species  in  our  fauna  are  concerned  this 
genus  is  a  composite  and  contains  three  distinct  forms. 

First. — Labial  palpi  normal,  the  second  joint  longer  than  the  terminal 
and  plurisetose  in  front.  The  anterior  and  middle  tarsi  are  dilated  nearly 
equally  and  biseriately  squamulose  beneath,  the  fourth  joint  emarginate. 
The  antennae  have  the  two  basal  joints  glabrous  and  also  a  small  portion 
of  the  base  of  the  third. 

I  believe  the  species  so  constituted  should  be  placed  in  Hurpalus, 
(Lee.  Proc.  Acad.  18G1,  p.  374).  They  are  dichrous,  vulpecnlus  and 
autumnalis. 

Second. — Labial  palpi  abnormal,  the  second  joint  bisetose  in  front  not 
longer  than  the  last.  Anterior  tarsi  of  male  normally  dilated  and 
squamulose  beneath,  the  fourth  joint  emarginate.  Middle  tarsi  narrowly 
dilated  but  distinctly  squamulose.  The  antennae  have  three  basal  joints 
entirely  glabrous. 

Here  belong  hadlipennls^  atrim,edrus,  nigrinus,  and  one  new  species 
all  of  which  should  be  referred  to  the  genus  Tachycelli:s  Morav. 

Baron  Chaudoir  (Rev.  Mag.  Zool.  18(j8),  first  suggested  the  placing 
of  these  species  in  Tuchycellns  but  the  characters  made  use  of  were 
of  such  a  trivial  nature  that  Dr.  LeConte  did  not  deem  it  advisable 
to  follow  him.  I  can  not  myself  agree  with  Chaudoir  in  adding  also 
vulpecidus,  dichrons  and  autummilis. 

In  the  same  paper  Chaudoir  makes  the  first  step  toward  the  re- 
establishment  of  Acupalpus  in  our  fauna  by  the  description  of  a  new 
species  {re.ctangidus),  included  in  the  list  above  given. 

Third. — The  remaining  species  belong  to  Bradt/ccUas  proper.     The

labial  palpi  are  as  in  Tachycellus.  The  anterior  tarsi  above  dilated. 
The  middle  tarsi  about  as  slender  as  in  the  female.  The  antennae  have 
at  most  two  basal  joints  glabrous  and  the  second  and  often  the  first 
are  hairy. 

From  the  above  notes  it  will  be  evident  that  the  genera  are  not  easily 
separable  except  both  sexes  are  at  hand.     The  iullowing  table  will  assist 
the  student  of  our  fauna.

The  last  two  genera  do  not  occur  in  our  fauna  and  are  introduced  in 
the  t;il)le  for  convenience  of  comparison.  I  observe  that  the  three  basal 
joints  are  glabrous,  that  is,  the  third  joint  is  not  punctured  and  pubescent 
in  the  manner  of  the  following  joints.  It  has  it  is  true  a  few  hairs  but 
the  surface  is  like  the  second  and  not  the  fourth.  In  these  genera  the 
hind  angle  of  the  thorax  bears  a  long  erect  seta,  presenting  the  only 
instance  in  wliich  this  is  the  ca.se  in  genera  with  one  supra-orbital  seta. 
Duval  refers  these  genera  to  the  Anisodactyli,  but  from  the  tarsal  vesti- 
ture  they  seem  more  properly  to  belong  here. 

As  already  remarked  three  species  formerly  placed  in  Bradycelhis 


184  OEO.    H.    HORN,    M.  D. 

are  included  in  Harpalns.  The  mouth  parts  of  vulpeculus  139,  show 

some   difference  from   those  figured   as  Marpalus,  but  the   other  two 

species  have  the  Hgula  and  paraglossae  as  in  fig.  188,  except  that  the 
paraglossfe  are  not  ciUate. 

Group  Anisodactvli. 

The  essential  character  of  this  group  is  that  the  dilated  tarsal  joints 
of  the  male  are  spongy  pubescent  beneath. 

As  constituted  by  Lacordaire  it  contains  very  diverse  forms — Ortlio- 
gonius  is  a  distinct  tribe,  Oratognathus  and  Flowma  are  Dapti,  Geo- 
hsenus  allied  to  Platt/nua  ;  Migadops,  Loxomerus  and  Brachycoelus  are 
Carabinae,  GynandropiiDi  and  Diavhromus  go  to  the  Harpali ;  Gynandro- 
tarsus  has  already  been  suppressed  in  Anisodacty/us,  and  I  hope  to 
show  good  reasons  for  doing  the  same  with  Gynandromorphus. 

The  genus  Anisodactylus  not  only  gives  its  name  to  the  group  but  is 
also  its  central  idea.  From  this  as  a  starting  point  the  relative  values  of 
the  genera  may  be  discussed,  as  a  convenient  point  of  comparison. 

In  a  ri!view  of  our  species  of  the  genus  published  by  me,  (Proc.  Am. 
Philos.  Soc.  1880,  p.  1(J2,  etc.),  will  be  found  a  full  discussion  of  the 
characters  which  serve  to  divide  the  species  in  subgenera  and  lower 
groups — the  trifid  anterior  tibial  spur,  the  spur  broader  at  middle  and 
the  slender  spur.  In  two  species  harpaloides  and  vpacidus,  the  first 
joint  t)f  the  anterior  tarsus  of  the  female  is  dilated  and  in  the  former 
that  joint  is  somewhat  prolonged  under  the  second. 

Gynamh'nmorphua  has  the  trifid  anterior  tibial  spur  in  both  sexes, 
the  first  joint  of  the  anterior  tarsi  dilated  in  the  female  while  the 
posterior  tarsi  are  somewhat  flattened  and  pilose  above.  In  the  first 
character  it  is  ecjually  related  to  the  Dichirus  and  Triplectrus  groups  of 
Anisodactylus,  by  the  second  to  the  latter  more  especially  and  by  the 
third  character  to  the  former  more  especially.  The  upper  surface  is 
densely  and  rather  coarsely  punctured  and  finely  pubescent.  I  have 
therefore  no  hesitation  in  placing  Gynundromorphus  as  a  division  of 
Anisodavtylus  intermediate  between  the  groups  Dichirus  and  Triplectrus. 

Xestonotus. — Anterior  tarsi  broadly  dilated  in  the  male,  the  first 
four  joints  densely  spongy  pubescent  beneath,  middle  tarsi'  with  four 
joints  less  widely  dilated  and  spongy  pubescent  beneath,  the  first  entirely 
glabrous,  posterior  tarsi  slender  and  long.  Elytra  with  one  dorsal  punc- 
ture. The  ligula  is  rather  narrow  and  parallel,  the  paragloss«3  broad 
and  a  little  longer  than  it. 

Comparing  the  diiferences  between  the  ligula  and  paraglossse  with 
those  observed  in  Ha r palm  there  does  not  seem  any  valid  reason  for 


AMERICAN    COLEOPTERA.

retaining  tlie  genus  apart  from  Anisodactylus,  and  the  species  will 
find  a  suitable  position  between  the  amaroidex  and  serkexis  groups 
of  that  genus. 

Amphasia. — Here  the  characters  are  essentially  those  of  Aniso- 
dacti/Ins  serlceus.  The  paraglossse  are  similar  in  form  to  Anisodactylus 
and  merely  a  little  longer. 

Anisotarsus.— The  sexual  characters  and  those  derived  from  the 
posterior  tarsi  are  precisely  those  of  Am'sodacfi/his  coenus  and  Isetus. 
The  paraglossse  are  a  little  broader  than  in  typical  Anisodncfi/li. 

Spon(Sopus.— The  ligula  and  paraglosste  are  intermediate  in  structure 
between  the  typical  Anisodactt/lus  and  Xeslu7iofus,  and  the  ligula  is  free 
for  a  greater  distance  at  tip.  The  sexual  characters  are  those  of  the 
amaroides  group.  The  posterior  tarsi  are  however  slender.  The  elytra 
being  punctulate  and  with  a  single  dorsal  puncture  this  species  forms  an 
intermediate  between  the  discoideus  group  and  serlceus. 

From  the  above  remarks  it  must  be  evident  that  my  opinion  is  that 
the  above  genera  are  inseparable  from  Anisodncti/lus.  I  have  examined 
the  species  from  every  possible  standpoint  and  4can  find  no  reason  either 
from  my  own  studies  or  the  remarks  of  others  to  do  otherwise  than 
su"":ested  above. 

While  I  have  given  these  genera  all  the  study  possible  with  me 
at  present,  I  consider  the  question  of  the  total  suppression  of  Aniao- 
ttirsus  and  Spoiujopns  still  open  for  further  discussion,  there  is  no 
doubt  in  my  mind,  however,  regarding  Gi/niindrumorphus,  Xestonotnn 
and  Amphasia. 

It  is  worthy  of  note  in  Anisi.dartijlus  that  we  may  have  more  than 
one  setigerous  puncture  at  each  angle  of  the  clypeus  while  in  most 
Carabidoe  there  is  but  one  and  even  this  may  be  lost. 

Sub-Family  FSE ID OM ORFHINjE. 

>liddle  coxal  cavities  enclosed  by  the  central  pieces  of  the  mi^so- 
aiid  metasternum.  Head  without  supra-orbital  setfe  and  with  grooves

great  part  superior,  very  widely  separated  beneath  from  the  mouth. 
Legs  short,  contractile,  tarsi  slender,  rigid. 

The  genera  which  compose  the  present  division  are  the  most  abnormal 
of  all  Carabidce.  That  they  belong  to  the  family  and  should  not  be 
separated  is  I  believe  now  generally  admitted,  the  only  difficulty  being 
their  proper  position  in  the  series,  and  from  my  own  study  they  do 
not  seem  to  be  well  placed  anywhere  and  are  equally  aberrant  in  any

position.  The  affinity  so  often  mentioned  in  the  direction  of  the  Gyrinidae 
seems  rather  feeble,  and  is  expressed  rather  in  an  outward  resemblance 
of  form  than  in  the  more  important  anatomical  details.     - 

There  seems  to  be  an  undiscovered  form  or  possibly  a  lost  type 
to  which  certain  tribes  of  the  Carabinae  and  Harpaliuae  as  well  as 
Amphizoidae  appear  to  point,  and  it  is  with  this  hypothetical  centre 
that  the  Pseudomorphinae  seem  to  be  allied.  The  tribes  referred  to 
are  Enceladini,  Siagonini  and  Ozaenini.  In  the  discussion 
of  the  Gyrinidae  there  will  be  found  important  reasons  why  we  cannot 
suspect  any  relation  between  it  and  the  presant  sub-family. 

One  tribe  alone  forms  the  sub-family. 

Tribe  XLVIII.  Pseudomorphini. 
AuteniiPe  usually  slender,  filiform,  ooinpressed  and  subserrate  in  Ade/otopu.i 
arising  under  a  moderately  dilated  frontal  plate,  the  three  basal  joints  glabrous, 
received  in  repose  in  grooves  of  greater  or  less  length,  within  the  eyes  beneath 
the  head.  Head  short,  obtuse,  deeply  inserted  in  the  thorax,  sides  of  front  more 
or  less  dilated  and  infringing  on  the  eyes  in  front,  clypeal  suture  rarely  visible, 
front  without  supra-orbital  setse.  Eyes  oval,  not  prominent,  usually  confined 
almost  entirely  to  the  upper  side  of  head  and  widely  distant  from  the  buccal

the  terminal  joint  cylindrical,  compressed,  obliquely  truncate  at  tip.  Mentum 
large  without  basal  suture,  deeply  emarginate  toothed  or  not,  the  epilobes  narrow, 
ligula  and  paraglossse  variable  in  form,  the  palpi  longer  than  the  maxillary,  the 
terminal  joint  cylindrical  and  obliquely  truncate  or  securiform.  Thorax  as  broad 
at  base  as  the  elytra  and  overlapping  them,  the  lateral  margin  more  or  less  ex- 
planate  and  often  fimbriate  but  without  the  usual  setue.  Elytra  oblong,  truncate 
at  tip,  not  margined  at  base,  lateral  margin  acute,  sides  narrowly  inflexed  but 
more  widely  near  the  base,  the  epipleurfe  proj)er  very  narrow,  no  internal  plica,

coxse.  the  epimera  distinct,  not  reaching  the  cijxal  cavity.  Metasternal  epimera 
distinct,  posterior  coxse  contiguous.  Legs  short  not  visible  beyond  the  elytra,  the 
femora  stout,  rather  deeply  channeled  beneath  and  receiving  the  tibiai,  the  latter 
slender  and  with  moderate  terminal  spurs,  the  anterior  tibiae  emarginate  within, 
the  inner  spur  remote  from  the  apex.  Tarsi  slender  very  feel)ly  fiexile,  the  (daws 
slender,  feebly  arcuate  and  simple. 

This  tribe  is  represented  in  -our  fauna  bv  the  j^rnus  Haeudoviorplta 
with  three  species. 

In  the  two  specimens  of  F.  Cronkhitei  before  me  the  fourth  and  fifth 
ventral  seoments  have  at  middle  a  short,  transverse,  pilose  band,  while 
P.  Behrensii  my  unique  presents  no  such  character.  This  may  be 
sexual.     I  have  observed  no  other  sexual  diflPerences.

Our  species  are  so  rare  that  it  was  impossible  to  procure  one  for 
dissection,  and  I  have  substituted  Sphallomorpha  quadrisignata  Cast., 
from  AustraUa,  (see  PI.  Ill,  fig.  4,  also  dissection  147). 


Additional  Notes. 
On  p.  ya  I  have  made  xise  of  the  expression  that  '-the  (posterior) 
coxae  reach  the  side  margin  of  the  body,  separating  the  metasternal 
side  pieces  from  the  first  ventral  segment."  By  this  I  mean  to  be 
understood,  the  side  margin  as  it  appears  from  the  examination  t)f  an 
entire  specimen,  the  limit  of  the  body  being  the  margin  of  the  elytra. 
The  extent  of  the  coxse  outwardly  is  such  that  the  wide  pieces  become 
more  dorsal,  they  are  never  cut  off  from  articulation  with  the  abdomen 
but  merely  hidden.  It  is  not  a  question  of  greater  or  less  inflexion 
of  the  elytral  margin,  lus  it  will  be  observed  in  tho.se  genera  with  most 
widely  inflexed  elytra  {C^chrus  et  al.),  that  the  coxae  do  not  attain  the 
side  margin  of  the  body.

From  the  families  of  Adephaga  given  on  p.  94  there  appears  to 
be  a  tendency  on  the  part  of  some  able  entomologists  to  exclude  the 
G-YRINID.'F.  I  biilieve  I  have  studied  this  type  with  some  care  and  the 
structure  of  the  external  skeleton  as  well  as  the  mouth  parts  seem  to  me 
so  plainly  Adephagous  as  to  leave  no  room  for  douljt.  It  is  true  the 
antennae  are  irregular  in  their  form,  the  eyes  are  so  broadly  divided  as 
to  make  a  superior  and  inferior  i)air  on  each  side,  and  in  Dineutua  X\w 
outer  or  palpar  lobe  of  the  maxilla  is  lost. ,  These  are  certainly  import- 
ant characters  but  must  not  be  allowed  to  outweigh  all  the  rest  of  the 
organizaticm.  The  Adephaga  do  not  present  an  unbroken  chain  and  in 
its  fragmentary  condition  some  aberration  must  be  expected.

After  entering  on  the  description  of  the  various  tribes  recognized  in 
the  preceding  pages,  I  have  used  Lacordaire's  first  volume  of  the  Genera 
as  a  convenient  means  of  comparison.  It  is  well  known  that  this  volume 
although  not  old  in  years  is  somewhat  antiquated  through  the  researches 
of  Schaum,  Chaudoir  and  LeConte,  but  with  all  its  defects  it  is  the  only 
general  system  of  Carabidae  extant.  Several  authors  have  started  in  an 
attempt  to  revise  the  system  but  beyond  the  arrangement  of  the  genera 
of  local  faunte  nothing  has  been  done.  It  has  been  easy  enough  as  far 
as  the  tribes  of  the  Carabin^e  extend,  beyond  this  all  is  in  confusion. 
The  present  essay  aims  to  go  a  step  farther  and  if  but  little  has  been 


188  GEO.    H.    HORN,    M.  D. 

accomplished,  it  is   hoped   that  discussion   will   clear  up   much  of  the 
obscurity  and  bring  some  order  from  the  existing  chaos. 

All  of  Lacordaire's  tribes  will  be  found  to  have  been  reviewed,  and 
from  among  the  genera  I  have  endeavored  to  select  for  special  study 
those  about  which  he  or  others  appeared  to  be  in  greatest  doubt.  The 
judgment  on  the  choice  of  genera  must  be  left  to  the  criticism  of  all 
who  choose  to  find  out  which  they  are  by  a  perusal  of  the  preceding 
pages  or  a  reference  to  the  index. 


That  section  of  the  genus  Oi/chrus  known  as  Sphaeroderus  has  been 
supposed  to  be  peculiar  to  the  eastern  portion  of  the  Atlantic  region, 
no  species  having  heretofore  been  found  west  of  the  Mississippi  River. 
Within  a  few  days  a  species  has  been  received  from  Washington 
Territory.  I  give  the  description  here  as  an  interesting  contribution 
to  geographical  distribution. 

Cji'ClirilS  {Sphccroderas)  relictllK  n.  sp.  — Fditii  ^^lender.  black,  sliining. 
Head  smooth.'  Thorax  cordiform,  one-fourth  broader  than  long,  sides  arcuate  in 
front,  oblique  behind,  base  not  broader  than  apex  and  one-third  shorter  than  the 
length,  hind  angles  slightly  obtuse,  margin  very  narrowly  reflexed,  apical  arcuate 
line  and  basal  transverse  line  moderately  deeply  impressed,  median  line  less 
deeply,  the  intra-angular  impressions  rather  deep  and  curved  in  front  toward  the 
median  line,  disc  very  little  convex,  surface  smooth,  slightly  wrinkled  posteriorly. 
Elytra  very  regularly  elliptical,  twice  as  wide  at  middle  as  the  thorax  and  a.  little 
more  than  one-half  longer  than  their  width,  margin  very  narrowly  retlexed, 
surface  with  a  slight  violet  tinge  with  numerous  rows  of  moderately  deeply  im- 
pressed punctures,  the  striise  irregular.  Body  beneath  smooth,  shining.  Length 
.68  inch;   17  mm. 

This  species  is  more  elongate  than  any  of  our  eastern  SjJinei-oderus, 
and  differs  also  in  the  absence  of  any  punctuation  at  the  base  of  the 
thorax  and  by  the  sculpture  of  the  elytra.  The  legs  are  also  more 
slender  and  longer  thaq  in  the  other  species.  The  general  aspect  of  the 
insect  is  that  of  a  Sphaerodei'us  imitating  Cijchrus  strlatopunctdtua. 
One  male  collected  at  Spokane,  Wash.  Terr,  by  Mr.  L.  E.  Ricksecker. 


To  the  Clivin;i3  belongs  the  European  genus  Realiela  Saulcy,  re- 
markable as  the  only  known  member  of  the  Carabinte  with  the  eyes 
so  reduced  as  to  be  with  difficulty  observed.  The  species  is  extremely 
small  (.00  inch)  even  for  a  member  of  the  tribe  to  which  it  belongs. 
Synonymous  with  this  genus  is  Spelseodj/tes  Mill.  A  figure  of  R.  luci- 
fuga  is  given  by  Saulcy,  Ann.  Ent.  Soc.  Fr.  1862,  pi.  viii,  fig.  5,  from 
which  it  seems  allied  to  Olivlna  rather  than  Di/schiriiix. 


AMERICAN   COLEOPTERA.  189 

In  the  Bullet.  Ent.  Soc.  Fr.  1881,  No.  17,  p.  U8,  M.  Abeille  de 
Perrin  presents  a  good  argument  for  the  union  of  Trechus  and  Anoph- 
thalmus.  The  series  of  species  in  our  fauna  is  too  small  for  me  to 
express  any  opinion,  but  from  the  ability  shown  by  M.  Abeille  in  more 
difficult  observations  I  have  no  doubt  he  is  entirely  correct. 

While  I  would  be  willing  to  accept  the  idea  above  indicated  I  am 
not  prepared  to  coincide  with  those  who  would  unite  Anillus  with 
Bembidium  on  the  ground  that  these  bear  the  same  relation  to  each 
other  that  Trechus  and  Anophthalmus  do.  Through  the  kindness  of 
Dr.  Dohrn  I  have  been  enabled  to  study  iScotodipnua  ( Microtyphlus), 
and  as  it  did  not  appear  to  present  anything  of  special  moment  for 
a  general  essay,  its  closer  examination  w;is  deferred  until  the  present 
time.  The  upper  surface  presents  no  peculiarities  of  moment  except 
that  I  do  not  find  the  elytra  truncate  as  stated  by  Linder,  (Ann.  Ent. 
Soc.  Fr.  1863,  p.  483,  pi.  ix,  fig.  7).  The  u.sual  setae  of  the  Bembidiini 
are  present  and  that  on  the  mandible  well  marked.  On  examining  the 
under  side,  which  I  had  omitted  to  do  at  first,  I  was  surprised  to  find 
the'  posterior  cozee  rather  wideli/  separated.  In  Anillus  the  same 
character  exists,  while  in  Anophthalmus  the  posterior  coxae  are  con- 
tiguous as  in  ordinary  Trechus.  This  structure  is  certainly  a  valid 
generic  difference  and  whatever  course  is  taken  with  Anophthalmus 
the  other  two  genera  must  remain.  Notwithstanding  the  small  size 
of  Scotodipnus  I  have  observed  the  internal  elytral  plica  of  the  Bem- 
bidiini, feeble  of  course,  but  quite  as  distinct  as  in  some  Tachtjs. 

In  my  "Synopsis  of  the  Silphidae,"  i^ Trans.  Am.  Ent.  Soc.  1880), 
I  have  directed  attention  to  the  fact  that  all  tlie  eyeless  genera  have  the 
posterior  coxae  separated,  but  I  am  not  able  to  explain  the  correlation 
of  these  distant  members  of  the  body.

Index  to  the  Coleoptera  described  by  J.  L.  L.eConte,  91.  D. 

BY    SAMUEL    HENSHAW. 

The  following  list  prepared  at  the  suggestion  of  Dr.  Horn  owes  much 
of  its  completeness  to  the  assistance  of  that  gentleman  and  Dr.  LeConte, 
both  of  whom  kindly  examined  the  manuscript  and  have  added  con- 
siderable synonymy  as  yet  unpublished. 

To  Dr.  Sharp  of  Thornhill,  Scotland,  I  am  indebted  for  a  similar 
service  with  the  Dytiscidae. 

It  may  be  noticed  that  a  number  of  the  names  adopted  are  of 
more  recent  date  than  those  suppressed,  (as  Evarthrus  vagans  G-349 
=  E.  Engelmanui  17-228,  Anisodactylus  similis  14-1 8;>  =  A.  semi- 
punctatus  G5-83)  ;  the  reason  for  this  is  that  the  retained  name  is 
either  more  expressive  or  one  that  has  come  into  general  use,  and  as 
both  the  retained  and  suppressed  names  were  proposed  by  the  same 
author  no  favoritism  is  shown.* 

As  a  rule  Catalogue  names  published  without  descriptions  are  not 
included. 

In  order  to  avoid  confusion  a  list  of  the  species  described  by  Major 
J.  E.  LeConte  is  appended. 

In  the  following  pages  the  first  number  after  a  generic  or  specific  name 
refers  to  the  title  in  the  accompanying  list,  the  second  the  page.  When 
a  species  was  described  under  a  difterent  generic  name  irom  that  used 
here,  the  original  name  follows  in  brackets. 

The  types  are  for  the  most  part  in  Dr.  LeConte's  cabinet.  When 
a  name  is  followed  by  *  the  type  is  with  Dr.  Horn,  when  by  *  *  with 
Mr.  Ulke,  other  exceptions  will  be  referred  to  by  note.

Hah  —Colorado  ;  Nevada  ;  (Morrison).  This  may  not  belong  to  the

ENTOMOLOGICAL    SECTION.  Vll 

Dr.  Horn  suggested  a  modification  of  the  table  of  Clivina  whit-h  was 
originally  published  by  Dr.  LeConte  in  Proc.  Acad.  1857,  p.  81,  and  since 
somewhat  changed  by  the  author  in  Bull.  Brooklyn  Ent.  Soc.  ii,  p.  32. 

Lateral  margin  of  thorax  attaining  the  basal  margin. 

Middle  tibiae  with  a  spur  on  outer  side  near  the  tip Species  1-8. 

Middle  tibise  without  spur Species  9-15. 

Lateral  margin  of  thorax  not,  attaining  the  base  but  forming  an  ante-basal  ridge. 

Middle  tibiae  without  spur Species  16-21. 

Species  1-15  have  many  dorsal  punctures,  16-21  two  or  none. 

Dr.  Horn  also  called  attention  to  the  fact  that  the  characters  used  in 
the  separation  of  the  genera  of  the  group  Clivinae  seemed  to  have  very 
little  value,  and  those  based  on  the  ligula  not  strictly  true.  An  iiiiportant 
difference  between  Clivina  and  Dj/schirius  seemed  to  have  been  entirely 
overlooked.  In  the  former  genus  the  terminal  joint  of  the  maxillary 
palpi  does  not  differ  materially  in  the  sexes,  while  in  the  latter  that  of 
the  male  is  much  more  dilated  and  on  the  under  surface  is  excavated, 
the  concavity  which  is  sharply  defined  is  membranous  and  probably 
sensitive.  The  two  genera  are  thus  distinctly  separable,  while  the  ligula 
and  paraglossse  do  not  differ  materially  in  all  the  genera  of  Clivintv. 

The  gToup  Scarites  is  separated  from  the  Clivinas  not  only  by  the  form 
of  the  antenuiB  and  mentum.  but  also  in  the  occurrence  of  but  one  supra- 
orbital setigerous  puncture  in  the  former  group  and  two  in  the  latter. 
A  fuller  discussion  of  the  genera  of  both  these  groups,  illustrated  with 
drawings  of  dissections  of  the  mouth  parts,  were  promised  in  a  UKjre 
extended  paper  which  would  soon  be  presented  for  publication. 

Dr.  Horn  also  exhibited  two  new  species  of  Desmocerus  which  he 
briefly  characterized  as  follows  : 

D.  californicus  n.  sp. — Black  opaque,  elytra  bluish-  or  greenish-black,  nar- 
rowly margined  at  base  and  sides  with  orange-red.  Head  and  thorax  densely  and 
moderately  coarsely  punctured,  the  latter  with  the  surface  regular,  and  with  a 
slight  tinge  of  bluish-green.  Elytra  densely  punctured,  the  punctures  near  the 
base  coarse  and  deep,  becoming  gradually  finer  and  denser  toward  the  apex,  sur- 
face black  opaque  and  with  a  bluish,  violaceous  or  greenish  tinge,  the  lateral  and 
basal  margins  narrowly  orange-red,  scutellum  and  a  small  spot  each  side  black. 
Body  beneath  and  legs  densely  and  rather  finely  j^wnetured,  the  metasternum 
very  finely  pubescent.     Length  .64  %  —.80  J  inch ;  16—20  mm. 

The  male  is  smaller  and  more  slender  than  the  female,  and  the  elytra 
gradually  narrower  to  apex  ;  the  five  basal  joints  of  the  antennae  are  also 
stouter  and  more  serrate. 

Collected  by  Mr.  H.  K.  Morrison  during  the  past  year,  in  the  southern 
part  of  California.

D.  cribripennis  n.  sp. — Black,  moderately  shining,  elytra  bluish  or  greenish 
more  or  less  metallic,  narrowly  margined  with  orange-yellow.  Head  coarsely  and 
deeply,  more  or  less  continently  punctured.  Thorax  coarsely  transversely  plicate 
by  the  confluence  of  the  punctures,  surface  irregular,  bronzed.  Elytra  very  coarsely 
and  deeply  punctured,  the  punctures  near  the  apex  very  little  smaller.  Scutellum 
and  a  small  sjjot  each  side  black.  Body  beneath  and  legs  finely  and  moderately 
densely  jiunctured,  the  abtlomen  less  densely  at  middle.  Length  .48  %  — .72  9  iuch ; 
12—18  mm. 

The  sexual  characters  are  as  in  the  preceding  species  but  less  marked. 
Collected  by  Mr.  Morrison  in  Washington  Territory. 

Dr.  Horn  stated  that  some  time  ago  he  exhibited  females  of  these  and 
supposed  them  merely  instances  of  dimorphism.  He  was  glad  to  be  able 
to  correct  his  own  mistake  and  place  the  species  in  their  proper  light. 

Desmocerus  now  contains  four  species,  three  of  Avhich  belong  to  the 
Pacific  fauna,  they  are  as  follows  : 

Elytra  at  basal  half  yellow,  apex  blue,  disc  finely  tricostate,  {elongatus  BL). 

palliatns  Forst. 
Elytra  either  entirely  yellow  or  margined  with  yellow,  not  costate. 

Male  elytra  orange-yellow,  female  with  discal  blue  space,  i)unctuation  moder- 
ately coarse,  a  little  finer  near  apex aureipeiiiiis  Chev. 

Elytra  similarly  colored  in  the  sexes,  both  narrowly  margined  with  yellow  at 
sides  and  base. 
Thorax  irregularly  jilicate,  elytra  coarsely  aud  deejily  punctured  from  base 

to  apex cribripennis  Horn. 

Thorax  densely  punctured,  regularly  convex,  elytra  moderately  coarsely  i)unc- 
tured  at  base,  more  finely  and  densely  at  apex caliTornicnS  Horn. 

The  last  three  are  the  Pacific  species  and  all  are  found  on  the  flowers 

of  Elder  (  Samhucus).

[Pai'eu  No.  L] 

Having  been  engaged  during  the  past  winter  on  a  study  of  the 
cynipidous  galls  of  Florida,  I  propose  to  give  the  results  of  my  in- 
vestigations in  some  short  papers. 

As  comparatively  little  of  importance  has  been  published  respecting 
the  galls  of  the  live  oak  Quercus  vh-ens,  I  make  that  the  subject  of  my 
first  contribution : 

The  (tALLS  of  the  Live  Oak,  Quercus  virens. 

Of  the  many  curious  galls  affecting  this  tree,  the  first  to  which  I  wish  to 
call  attention  is  one  which  may  be  designated  by  the  popular  name  of 
The  Live  Onh  Pea  Gall. 

Baron  Osten  Sacken  was  the  first  to  give  an  account  of  it  twenty 
years  ago  in  his  paper  entitled,  "  On  the  Cynipidae  of  the  North  American 

MONTHLY    rnoC.  ENT.   SEC.  A.  N.  S.  (2)  MAY,  1881.

Oaks  and  their  Galls,"  p.  57,  published  in  the  Proc.  Entom.  Soc.  Phila. 
1861.     He  says: 

'■'■Quercus  virens,  Live  Oak. — Small,  globular  galls  on  the  under  side 
of  the  leaf.  Diam.  0.15  to  .2."  Pale  brownish  when  ripe;  filled  inside 
with  a  spongy,  cellular  mass,  which  is  more  dense  than  that  of  the  pre- 
ceding {C.  conJiue7is),  and  not  unlike  the  pith  of  a  reed  in  texture. 
Single  kernel  in  the  centre. 

"  I  am  indebted  for  these  pretty  galls  to  Dr.  Foreman,  who  brought 
them  from  Greorgia,  and  although  I  do  not  know  the  fly,  I  have  no  doubt, 
from  the  structure  of  the  gall  that  it  is  the  produce  of  a  C^nips." 

In  this  supposition  my  researches  prove  him  to  be  correct.  Early 
this  winter,  I  procured  specimens  of  this  gall  from  a  tree,  the  leaves  of 
which  were  literally  covered  with  them,  and  from  which  I  have  bred  the 
gall-fly  and  its  parasites,  the  latter  will  be  described  in  a  future  paper. 

Cynips  q.  virens  n.  sp. 

Galls. — Small,  globular,  the  size  of  a  pea  or  slightly  larger ;  from  two 
to  ten,  attached  to  the  under  side  of  the  leaf;  pale  brownish  in  color, 
filled  inside  with  a  dense,  yellowish-brown,  spongy,  cellular  mass.  A  single 
kernel  in  the  centre.     Diameter  0.15  to  0.25  inch. 

Gall-Fly. —  9  • — Length  .15  inch.  Head  reddish-brown,  finely  punctate,  pubes- 
cent; mandibles  black;  antennae  13-jointed,  reddish-brown,  first  two  joints  some- 
what fulvous,  nearly  connate,  third  longest,  about  five  times  as  long  as  second, 
following  joints  gradually  decreasing  in  size,  excepting  thirteenth  which  is  slightly 
longer  than  twelfth  and  infuseated;  thorax  brown,  coarsely  punctate,  pubescent; 
parapsidal  grooves  distinct,  two  longitudinal  grooves  on  preescutellum  blackish ; 
scutellum  round  very  finely  rugoso-punetate,  pubescent;  wings  hyaline  and  re- 
markably long,  veins  brownish  and  thick,  radial  area  almost  closed,  areolet  distinct, 
petiolated,  abdomen  dark  reddish-brown,  all  segments  visible,  basal  half  of  second 
light  reddish  ;  legs  light  reddish-brown,  posterior  femora  slightly  infuseated. 

Described  from  one  bred  specimen.  Although  I  have  nearly  two 
hundred  specimens  of  the  galls  in  boxes,  I  have  raised  but  a  single 
Ci/iiips,  and  that  issued  from  the  gall  early  in  February. 

The  Live  Oak  Potato  Gall. 

By  the  above  name  I  designate  a  gall  which  is  found  quite  abundantly 
on  the  twigs  and  branches.  It  is  evidently  the  same  mentioned  by 
Baron  Osten  Sacken  (loc.  cit.  p.  259,  1862-).     He  says: 

"Quercus  vlrens,  Live  Oak. — Woody  swellings  on  the  limb.  The 
specimen  communicated  by  Mr.  Grlover  is  _a  fragment  of  a  branch  about 
one  and  one-half  inches  long,  with  two  such  swellings  ;  the  one  is  rounded 
about  0.7  long  and  0.5  broad ;  the  other  much  smaller.  I  opened  the 
latter  and  found  on  the  inside  a  small  hollow  from  the  structure  of  which 
I  have  no  doubt  that  the  gall  is  the  produce  of  a  Oj/nips." 


ENTOMOLOGICAL    SECTION.  XI 

I  obtained  specimens  of  this  gall  early  in  January  and  February,  and 
have  succeeded  in  raising  several  of  the  flies.  Many  of  these  galls  are 
picked  by  birds  and  gnawed  by  mice ;  both  of  which  evidently  highly 
esteem  the  rich,  juicy  morsel  within. 

Cynips  q.  batatoides  n.  sp. 

Galh. — Abrupt,  potato-like,  irregular  swellings  of  the  twigs  and 
branches,  varying  in  size  and  form,  from  0.4  to  0.7  and  sometimes  an 
inch  long,  and  0.3  to  half  an  inch  or  more  broad ;  the  outer  surface  is 
rough  of  the  same  color  i^s  the  bark ;  internally  it  is  white  and  in  con- 
sistency not  unlike  a  potato.  No  kernels;  each  insect  separated  by  a 
very  thin,  hardly  perceptible  parchment-like  substance.  In  one  of  the 
galls  I  counted  fifteen  gall-flies. 

Gall-Fly.—  9  .—Length  .12  inch.  Head  brownish-red,  finely  punctate,  slightly 
pubescent,  mandibles  bidentate,  tips  black;  palpi  yellowish  ;  antennse  15-jointed, 
reddish-brown,  joint  third  not  quite  thrice  as  long  as  first  and  second  combined, 
joints  four  to  eight  subequal,  nine  to  fifteen  about  equal,  terminal  joint  smallest; 
thorax  more  coarsely  punctate,  brownish-red,  covered  with  fine,  short,  whitish 
pubescence,  parapsidal  grooves  indistinct,  two  longitudinal  grooves;  seutelluni 
rugoso-punctate,  slightly  ridged,  ridge  more  perceptible  anteriorly  and  blackish ; 
wings  hyaline,  veins  black,  radial  area  open,  areolet  distinct,  petiolated  ;  abdomen 
smooth  and  polished,  of  a  uniform  reddisli-brown ;  legs  yellowish  or  yellowish-red, 
thighs,  coxfe  and  trochanters  darker,  feet  black. 

Described  from  numerous  bred  specimens  all  females. 

The  structural  characters  of  this  species  indicate  the  possibility  of  its 
belonging  to  Giraud's  genus  Dn/cosmus,  as  defined  by  Baron  Osten 
Sacken,  (loc.  cit.  4th  article,  p.  337). 

The  Bud-like  Gall  of  the  Live  Onk. 
This  gall  seems  to  have  been  entirely  overlooked  by  all  observers ;  it  is 
difficult  to  see  why,  for  although  not  nearly  so  plentiful  as  the  previously 
described  species,  it  is  yet  by  no  means  rare  and  quite  noticeable  upon 
the  ends  of  the  twigs. 

Cyni|>!>i  q.  >*ucciiii|>es»  n.  sp. 

G^a//.s-.— Clusters  of  from  five  to  twenty  small  galls  crowded  around 
a  terminal  twig  or  branch;  globular,  or  bud-like  in  form;  externally 
yellowish-brown  with  a  surface  like  buckskin,  becoming  black  with 
age ;  internally  hard  and  tough  with  a  single  kernel  hard  and  smooth. 
Diameter  from  .10  to  0.2  inch.

antennfe  1.3-jointed,  reddish-brown,  pubescent ;  third  joint  thrice  as  long  as  second, 
slightly  infuscated,  fourth  joint  nearly  as  long  as  third,  seventh  to  twelfth  about 
equal;  thorax  reddish-brown  rather  densely  pubescent,  two  black  subdorsal  vittaj

tween these  and  just  back  of  the  black  vittse,  converging  towards  scutellum  not 
quite  reaching  hinder  edge;  the  grooves  are  blackish  and  also  the  surface  of  the 
mesothorax  a  short  distance  along  their  edge ;  scutellum  roundish,  punctate  and 
pubescent ;  wings  hyaline,  veins  brownish  all  strongly  defined,  radial  area  nearly

Described  from  one  bred  specimen. 

Thr  Leafy  Gall  of  (he  Live  Oak. 

Another  curious  and  by  far  the  most  interesting  gall  I  have  yet  found 
in  Florida,  is  that  to  which  I  have  given  the  above  name.  Growing  as 
it  does  in  the  bud  axil  of  the  leaf,  and  not  unfrequently  iu  close  proximity 
to  the  others,  the  gall  would  naturally  be  taken  by  most  observers  for 
the  blossom  of  the  oak ;  indeed  I  never  until  lately  suspected  it  to  be 
the  product  of  a  Ct/nips. 

On  page  72,  vol.  2,  of  "  The  American  Entomologist,"  is  figured  a  gall 
discovered  by  II.  F.  Bassett,  so  well  known  for  his  researches  in  this 
interesting  branch  of  entomology,  which  will  give  one  a  fair  idea  of  the 
species  under  consideration. 

At  first  I  was  inclined  to  believe  my  species  and  his,  which  he  calls 
Cj/nlps  frondom  identical;  but  on  a  careful  study  of  his  description  of 
the  gall,  (he  does  not  characterize  the  insect  producing  it),  I  have  no 
hesitancy  in  describing  it  as  new. 

Mr.  Bassett  found  his  species  at  Watcrbury,  Conn.,  on  the  Chincjuapin 
Oak,  Q.  prlnoldeSj  while  Walsh  found  it  on  the  Bur  Oak  and  White 
Oak;  vide  Proc.  Entom.  Soc.  Phil.  p.  G8,  18G4-. 

He  says :  "  When  mature  it  often  attains  a  diameter  of  two  and  a 
quarter  inches,  and  the  modified  leaves  of  which  it  is  composed  are  then 
much  longer  and  proportionally  much  wider  than  at  first,  so  that  instead 
of  being  what  the  botanists  term  '  lanceolate,'  they  become  oval  with 
their  tips  usually  acute." 

Bassett  says :  "  The  cells  containing  the  larva  are  smooth,  shining, 
oval,  about  one-eighth  of  an  inch  long." 

Walsh  also  says :  "  The  larger  ones  enclose  four  or  five  cells  and  when 
the  gall  becomes  mature,  the  cells  are  gradually  disengaged  from  their 
leafy  matrix  and  drop  to  the  ground,  where  no  doubt  the  larva  will  pass 
the  winter  more  agreeably  among  the  masses  of  dead  leaves,  which 
accumulate  in  such  situations,  than  it  would  do  if  it  were  exposed  aloft 
to  the  stormy  blasts,  and  the  cold  driving  sleets  of  the  dead  season  of 
the  year."  , 


ENTOMOLOGICAL    SECTION.  XUl 

Now,  the  largest  specimen  I  have  ever  found  of  the  present  gall,  and 
I  have  collected  hundreds,  is  never  more  than  three-quarters  of  an  inch 
in  diameter,  and  instead  of  the  leaves  being  oval,  they  are  strictly 
lanceolate ;  the  cells  or  kernels  too,  instead  of  being  smooth,  are  pitted, 
somewhat  like  a  peach  stone.  They  likewise  never  drop  to  the  ground, 
but  remain  cemented  to  their  cup,  and  the  fly  escapes  by  pei'forating 
a  hole  in  the  top.  I  have  found  hundreds  of  the  black  dry  galls 
containing  cells  so  perforated,  and  have  never  seen  more  than  one  cell 
to  a  gall. 

Cynips  q.  foliata  n.  sp. 

Galls. — In  outline  urn-shaped,  composed  externally  of  numerous, 
lanceolate,  leafy-like  spines,  developed  from  the  axillary  leaf  bud ;  dia-

greyi.sh  acorn-lfke  cup,  with  a  single  kernel  imbeded  half  way ;  cup 
.20  inch  in  diameter.  Kernel  brownish  .15  to  .18  inch  long  by  .07  to

Described  from  numerous  bred  specimens. 

The  Live  Oak   Woolij  Gall. 
This  unique  and  beautiful  little  species  approaches  nearest  to  the  one 
described  by  Dr.  Fitch,  (see  Ann.  Report  N.  Y.  State  Agi-i.  Soc.  Fifth 
Report,  p.  814),  under  the  name  of  C.  q.  lana,  readily  distinguished  from 
it,  however,  by  size,  coloration  and  in  having  but  14-jointed  antennae. 

Cynips  q.  lanigera  n.  sp. 

Gall. — Small,  flattened,  circular  or  in-egular  tufts  of  rather  long 
whitish  or  ferruginous  wool,  on  the  under  parts  of  the  leaf;  attached 
generally  to  the  principal  vein  and  covering  from  two  to  six  small, 
irregvilar,  smooth  brownish  seed-like  kernels,  .06  to  .08  inch  in  diameter. 
Diameter  of  wooly  covering  .02  to  .03  inch.

Proceedings  of  the  Entomological  Section  of  the  Academy  of  Natural 
Sciences,  1881,  pp.  1 — 8.     From  the  Publication  Committee. 

May  13,  1881. 
Director  Dr.  LeConte  in  the  chair. 

The  Publication  Committee  laid  upon  the  table  (pages  33 — 48)  of 
volume  ix,  of  the  Transactions  of  the  American  Entomological  Society, 
printed  since  the  last  meeting. 

The  Publication  Committee  reported  that  work  had  been  resumed  on 
the  Transactions  and  Proceedings.  A  new  press  of  a  much  improved 
model  had  been  procured,  and  while  the  impression  consisted  of  but  two 
pages  the  work  can  be  more  expeditiously  and  cheaply  done  than  by  the 
old  press.  The  same  standard  of  good  presswork  will  be  maintained  and 
the  reputation  which  our  publications  have  attained  as  one  of  the  best 
printed  scientific  serials,  will  still  continue. 


ENTOMOLOGICAL    SECTION.  XV 

The  old  press  is  broken  in  such  a  manner  as  to  render  its  repair  more 
costly  than  the  Committee  at  first  realized  and  it  was  resolved  to 
abandon  it  entirely.  This  old  press  has  now  been  in  use  about  nineteen 
years,  doing  all  the  work  on  five  volumes  of  the  Proceedings  and  eight 
of  the  Transactions  and  two  of  the  Practical  Entomologist,  beside  much 
other  miscellaneous  entomological  printing. 

It  was  the  gift  of  Dr.  Thomas  B.  Wilson,  and  with  the  full  supply  of 
type  the  Committee  have  been  enabled  to  continue  to  the  present  year 
without  either  much  repair  to  press  or  renewal  of  type.  Our  present 
volume  (vol.  ix),  however,  begins  with  an  almost  entirely  new  supply 
of  type. 

The  Committee  hope  to  complete  a  volume  with  the  present  year, 
with  at  least  three  hundred  pages,  and  from  the  information  in  our 
possession  the  number  of  plates  will  be  a.s  great  or  greater  than  in 
any  preceding  volume. 

In  behalf  of  the  author,  Dr.  Horn  presented  the  following  paper, 
entitled 

On  the  €YNIPIDOUS  GALLS  of  Florida.

[Paper  No.  2.] 

GrALLs  ON  Catesby's  Oak,    Qucrcus  cafeKbi^i. 
I  have  found,  two  galls  on  this  oak  from  only  one  of  which  have 
I  been  able  to  breed  the  flies.     This,  however,  is  quite  an  interesting 
little  species.

The  Galls  of  the  Water  Oak,   Quercus  aquatica. 
Three  or  four  galls  are  found  on  this  oak.    The  first  may  be  known  as 

The  Woo/i/  Gall  of  the  Water  Oak. 
Cynips  q.  Tiiriierii  n.  sj). 

Galls. — Crlobular,  woolj  galls,  the  size  of  an  oxheai't  cherry,  attached 
to  the  aments  of  Quercus  aquatica.  Externally  covered  with  dense,  fine, 
rather  long  wool,  white  at  first,  but  becoming  rusty  with  age  ;  internally 
consisting  of  numerous,  triangular  seed-like  kernels,  each  kernel  containing 
two  cells.     Lsngth  of  kernel  .12  inch.     Diameter  of  gall  one-half  inch. 

Gall-Fh/. —  9  •  —Length  .07  inch.  Head  and  abdomen  reddish-brown  ;  thorax 
darker  brown.  Head  finelj'  punctate,  not  pubescent,  palpi  pale  yellowish,  tips

brown,  eoxse,  femora  and  tibise  punctate,  posterior  femora  and  tibia;  darker. 

Described  from  three  bred  specimens  which  issued  from  galls  April  28th. 

This  interesting  gall,  I  take  pleasure  in  naming  after  my  friend  Dr.  R. 
S.  Turner  of  Fort  George,  Florida,  who  was  the  first  to  bring  me  speci- 
mens. I  have,  however,  since  found  it  (juite  abundant!}'  on  several  trees 
in  Jacksonville. 

Two  other  globular  wooly  galls  are  known  to  me,  Gtjnlps  q.  seminator 
Harris,  and  Gi/nips  q.  operator  Osten  Sacken.  My  species  may  at  once 
be  distinguished  from  these  by  its  smaller  size  and  by  having  but  13- 
jointed  antennae  in  9  •  ^'  'J-  operator  is  9  12-jointed  antennae,  .12  to

Galls. — Globular,  hollow,  succulent  galls,  of  a  plum  color,  growing 
through  the  leafy  expansion  of  the  newly  formed  leaf,  projecting  about 
equally  from  the  upper  and  on  the  under  surface  of  the  leaf,  containing 
a  yellowish,  slightly  elongated  kernel,  which  rolls  freely  aboiit.  Diameter

Described  from  numerous  specimens  raised  in  March. 

The  GrALLS  op  the  Willow  Oak,   Quercus  hnu-ifnllse. 
TliLs  particular  species  of  oak  is  classified  by  botanists  as  a  variety  of 
Quercus  jjhel/os,  and  from  it  I  have  obtained  nine  distinct  species  of  galls. 

The  Cherry  Stone  Leaf  Gall. 

This  popularly  designates  a.  unique  gall  that  appears  early  in  February 
and  March,  on  the  tender  new  leaves — fref(uently  three  on  a  leaf.  It  may 
possibly  be  the  one  referred  to  by  Prof.  Westwood  as  described  by  Bosc, 
from  Georgia,  vide  Intro.  Entom.  vol.  2,  p.  181,  ed.  1840.     He  says: 

"  Another  gall  of  the  size  of  a  pea,  found  on  another  species  of  oak 
has  the  outer  surface  very  thin,  and  encloses  in  the  interior  a  small  ball 
the  size  of  a  grain  of  millet  which  rolls  about,  and  within  which  the 
larva  is  lodged.  M.  Bosc  opened  hundreds  of  these  galls  without  being 
able  to  learn  the  true  nature  of  this  production." 

Baron  Osten  Sacken,  loc.  cit.  p.  62,  discovered  a  similar  gall  Cynips  q. 
palustris  on  Quercus  palustris.  My  species  is  at  once  distinguished  from 
it  by  having  14-jointed  antennae  in  '^  ,  va.  punctation,  coloration,  by  the 
veins  of  wings  being  black,  and  by  the  long  bent  peduncle  in  the  %  . 
It  evidently  belongs  to  Hartig's  genus  Spathegaster. 

Spathegaster  q.  laiirifolise  n.  sp. 

Galls. — Green,  globular,  hollow  galls,  growing  through  the  leafy 
expansion  of  the  newly  formed  leaf,  projecting  about  equally  from  the 
upper  and  on  the  under  surface  of  the  leaf,  the  size  of  a  cherry  stone 
and  when  removed  not  unlike  it  in  shape,  containing  a  yellowish,  slightly 
elongated  kernel,  which  rolls  freely  about.  Length  .20  to  .25  inch, 
.15  or  more  through. 

Gafl-Fli/.—  ^  .—Jjcngth  .10  inch.  Black,  head  slightly  but  faintly  punctured, 
mouth  parts  reddish,  palpi  yellowish ;  antennae  14-jointed,  joints  one  and  two 
yellowish,  others  dark  reddish-brown,  pubescent,  third  joint  nearly  thrice  as  long 
as  second;  thorax  smooth  but  appearing  microscopically  punctate  with  a  high 
power,  parapsidal  grooves  moderately  distinct,  longitudinal  furrows  distinct ; 
scutellum  deeplj'  rugoso-punctate,  opaque  and  slightly  hair}"- ;  abdomen  globose, 
smooth,  black  and  highly  polished;  wings  hyaline,  veins  black:  legs  yellowish- 
red,  posterior  coxre  excepting  apex  and  feet  black.

wings  very  long  reaching  way  beyond  tip  of  abdomen  ;  abdomen  small  triangular, 
compressed,  with  a  very  long  peduncle,  slightly  bent  downwards  before  the  middle ; 
otherwise  as  in  lemale. 

Described  from  over  one  hundred  specimens  bred  in  March. 

On  a  %  cynips,  cUnging  to  the  long  curved  peduncle,  I  detected  a 
curious  gamasid  mite  but  0.2  mm.  long.  It  was  of  a  reddish-brown 
color,  oval,  coriaceous  and  pubescent ;  with  eight  remarkably  long  hairy 
legs,  the  posterior  pair  being  longest,  and  the  cephalothorax  separated 
from  the  abdomen  by  a  transverse  suture  and  with  the  head  rather 
pointed.  It  evidently  belongs. to  the  genus  Sejiix  and  may  be  known  as 
Scjus  ci/nipufis. 

Another  curious  gall,  constructed  on  the  same  principle  as  above  but 
smaller  and  not  projecting  through  the  leaf,  was  detected  the  middle 
of  April.

Galls. — Small,  globular,  slightly  elongate,  greenish-yellow,  succulent 
galls, .  attached  to  the  principal  vein  on  the  under  surface  of  the  leaf, 
hollow  inside  with  a  pupa-like  kernel ;  fly  escaping  by  perforating  a 
hole  through  the  upper  surface  of  the  leaf.  Diameter  transversely  .06 ; 
vertically  .10  inch. 

(iatl-Fly. —  9  • — Length  .07  inch.  Black,  head  finely  and  evenly  punctate ;

others  short  and  equal,  terminal  twice  as  long  as  penultimate;  thorax  rugoso- 
punctate,  parapsidal  grooves  distinct,  two  longitudinal  grooves  converging  pos- 
teriorly; scutellum  deeply  rugoso-punctate,  slightly  elevated  posteriorly  and  de- 
pressed and  with  a  large  deep  fovea  at  base,  not  pubescent ;  pleurae  deeply  aciculate ; 
wings  hyaline,  veins  reddish-brown,  areolet  nearly  closed,  radial  area  open; 
abdomen  black  and  highly  polished,  last  ventral  valve  projecting ;  legs  reddish- 
yellow,  coxfe  black. 

Described  from  2   9   specimens  bred  the  last  of  April. 

Another  gall  found  on  the  under  surface  of  the  leaves,  produces  a 
very  roughly  punctured  cynips  which  may  be  known  as 

Cynsps  q.  riigosa  n.  sp. 

Gdi/s. — Semispherical,  greenish-yellow,  smooth,  hard  galls,  attached  to 
the  under  surface  of  the  leaf,  slightly  contracting  the  leaf  on  the  upper 
surface,  but  not  projecting,  either  flat  or  slightly  concave ;  internally 
consisting  of  a  hard  fibrous  substance  in  the  centre  of  which  the  larva 
is  transversely  placed ;  fly  escaping  by  perforating  a  hole  through  the 
upper  surfiice  of  the  leaf.  Diameter  transversely  .20  inch ;  through  or 
vertically  .08  to  .10.

The  Galls  op  the  Upland  Willow  Oak,   Querent  dnerea. 
There  are  several  galls  found  on  this  tree,  but  by  fir  the  most  import- 
ant is  a  large  spherical  gall,  which  may  popularly  be  termed 

The  Up/and   Wi/foiv  Oak  Apple  Gall. 
Cyiiips  q.  ciiierea  n.  sp. 

Galls. — Large,  perfectly  spherical  galls  attached  to  the  twigs  and 
limbs,  of  a  dark  crimson  color  mottled  with  small  spots  of  a  lighter 
color.  A  single  kernel  in  the  centre  held  in  place  by  dense,  brown- 
ish, spongy  filaments.  Diameter  one  and  one-fourth  to  one  and  one- 
half  inch.

Head. small,  on  vertex  slightly  pubescent,  thicker  back  of  the  eyes,  almost  free  on 
face;  eyes  dark  brown ;  mandibles  black;  antennae  1.3-jointed,  short  not  reaching 
to  back  of  scutellum  :  thorax  broad,  robust,  convex,  parapsidal  grooves  almost 
obsolete,  longitudinal  furrows  wide  apart  and  almost  parallel,  indicuited  by  coarse 
punctures,  a  deep  transverse  furrow  dividing  mesothorax  from  scutellura,  a  few 
microscopical  whitish  pubescence  towards  head,  disk  free;  scutellum  round,  ele- 
vated, deeply  irregularly  rugoso-punctate,  free  from  pubescence,  excej^ting  a  few 
microscopical  whitish  hairs  more  perceptible  at  posterior  margin,  two  deep  round 
foveae  not  quite  separated  by  the  pointed  process  of  the  scutellum,  which  does  not 
reach  the  margin,  pleurae  rugoso-punctate,  pubescent,  as  well  as  the  triangular 
piece  beneath  the  wing  and  the  metathorax ;  abdomen  bright,  smooth,  reddish-

area  open,  a  large  brown  blotch  occui^ying  basal  half  of  radial  area  and  apical 
third  of  areolet,  also  extending  slightly  along  the  cubitus ;  basal  vein  thick  and 
clouded  with  brown;  anal  vein  brown  from  opposite  tip  of  areolet;  tip  of  radial 
vein  pale,  subcostal  vein  becomes  brown  as  it  approaches  basal  vein  and  be- 
comes pale  again  just  before  joining  the  large  brown  blotch;  legs  reddish-brown, 
pubescent. 

This  no  doubt  will  prove  to  be  related  to  the  dimorphic  group  of 
Ci/nips — spang ijica,  aciculata,  etc. 

I  noticed  smaller  galls  on  the  trees  during  the  winter,  but  all 
were  empty  and  have  produced  nothing  but  Chalcid  flies — CaUimeme, 
Pteromalus,  &c. 

The  summer  galls  will  probably  produce  the  two  gendered  form.

entomological  section.  xxi 

June  13,  1881. 

Director  Dr.  LeConte  in  the  chair. 

The  Publication  Committee  laid   upon  the  table  pages  49 — 64  of 

volume  ix  of  the  Transactions  of  the  American  Entomological  Society, 

and  also  pages  ix — xx  of  the  l^roceedings  of  the  Section,  printed  since 

the  last  meeting. 

Dr.  LeConte  desired  to  record  the  following  notes  of  synonyms  and 
habits  of  Coleoptera. 

Cicindela  Sommeri  Mannh. — This  common  Mexican  species  was  found 
by  Mr.  H.  Edwards,  at  San  Diego,  Cala. 

Carabus  truncaticollis  Eschsch. — Occurs  in  the  higher  parts  of  the 
Sierra  Nevada,  Cala.,  (II.  Edwards). 

Axinopalpus  Lee. — Ann.  Lye.  Nat.  Hist.  N.  Y.  v,  174,  (1846),  has 
priority  over  Varlopalpus  Sol.,  Gray,  Chili,  iv,  148,  (1849).  The  con- 
fusion in  this  synonym  has  been  produced  by  a  typographical  error  in 
the  INIunich  Catalogue,  in  which  the  date  attributed  to  my  genus  is 
printed  1851  instead  of  1846.  The  verbal  expansion  of  the  name  to 
Axinopselaphus  seems  unnecessary  and  scholastic.

Platycerus  Agnssii. — I  have  seen  (juite  a  large  number  of  specimens 
of  this  species,  but  have  not  observed  any  sexual  characters  worthy  of 
note.  Mr.  Edwards  has  kindly  given  me  a  specimen,  which  by  the  greater 
length  of  the  antennal  lamelhr)  is  evidently  a  S  .  .  The  ninth  and  tenth 
joints  of  the  antennae  are  more  than  twice  wider  than  long ;  the  mandibles 
are  slightly  more  prominent ;  the  legs  are  longer  and  thinner  ;  the  tibia) 
are  less  strongly  toothed  and  the  tarsi  are  as  long  as  the  tibisc,  while  in 
the  9  they  are  about  one-third  shorter.  The  prothorax  is  less  dilated 
on  the  sides  and  less  constricted  at  the  base  than  in  the   9  •

Dr.  LeConte  also  mentioned  an  extraordinary  change  of  color  dependent 
on  emotion  or  nervous  excitement,  which  he  had  observed  in  some  living 
specimens  of  Coptocycla  aurichakea,  which  he  had  recently  received  from 
Dr.  M.  Groldsmith,  Rutland,  Vt.,  by  whom  they  were  found  perforating 
holes  in  the  leaves  of  Ipomaea.  The  specimens  not  only  varied  greatly 
in  color,  some  having  the  elytral  disc  black  with  golden  spots,  while  in 
others  (var.  pallida),  the  whole  disc  was  golden,  but  when  frightened, 
the  gold  color  disappeared  completely,  and  the  insects  assumed  the  same 
dull  reddish-yellow  which  they  have  when  preserved  in  collections.  In 
recovering  their  metallic  color  they  passed  through  various  grades  of 
bluish-pearl  and  violet,  until  they  again  became  bright  golden.  This 
phenomenon,  which  so  far  as  Dr.  LeConte  knew,  had  not  been  hereto- 
fore recorded,  and  to  which  his  attention  has  been  called  by  Dr.  Gold- 
smith, is  a  very  singular  one,  and  deserves  the  careful  observation  of 
microscopists. 

Dr.  Goldsmith  has  also  observed  that  the  difference  between  these  two 
reputed  distinct  species  is  sexual,  the  guttata  form  having  a  black  disc 
with  golden  spots  being  the   S  ,  very  similar  to  C  guttata. 

He  placed  one  of  the  spotted  individuals  under  a  glass  with  two  of 
those  having  a  uniformly  disc.  After  a  short  time  amatory  relations 
were  established  between  the  former  and  one  of  the  latter.  What 
occurred  subsequently  is  thus  narrated  : 

"  Mr.  spotted-hack  forthwith  became  of  a  greenish-gold,  and  Mrs. 
pallida  a  yellowish-gold.  The  other  Miss  lost  her  beauty  and  became 
the  dingy  thing  she  is  on  wash  days.  I  uncovered  the  vessel  and  some- 
what rudely  disturbed  their  beatitude,  and  immediately  Mr.  and  Mrs. 
both  assumed  their  ordinary  wash  day  clothes.  The  fact  is,  gold  and 
jet  are  the  colors  of  the  male  when  undisturbed,  greenish-gold  in 
copula,  and  dingy  when  disturbed.  Both  when  recovering  from  fright 
become  at  first  a  beautiful  glistening  purplish  mother-of-pearl,  then  the 
male  gold  and  jet,  and  the  female  gold." 

These  interesting  observations  may  serve  to  diminish  the  very  large 
number  of  nominal  species  in  the  books. 


ENTOMOLOGICAL    SECTION.  XXIU 

Dr.  Horn  exhibited  the  drawings  which  form  the  eight  plates  to 
accompany  the  paper  presented  for  publication.  Special  attention  was 
called  to  those  figures  which  illustrate  the  definition  of  the  families 
composing  the  Adephagous  series  of  Coleoptera,  a  discussion  of  this 
matter  being  necessary  before  a  consideration  of  the  Carabidae.  This, 
Dr.  Horn  said,  was  necessary  in  consequence  of  the  diverse  opinions  ex- 
pressed by  various  authors  concerning  Amphizoa,  PeloUus  and  Haliplus. 
By  well  defined  structural  characters  not  hitherto  observed  it  was  shown 
that  these  are  really  types  of  distinct  families  equivalent  to  the  Carabidse 
or  Dytiscidfe.  Dr.  Sharp  in  a  late  paper  had  included  Amj^hizoa  and 
PehbiuH  in  the  Dytiscidfe  while  Chaudoir's  latest  opinion  was  in  favor 
of  retaining  the  former  in  the  Carabidae. 

Dr.  Horn  stated  that  he  regretted  to  differ  so  completely  with  such 
eminent  authority,  but  the  characters  in  which  these  genera  differ  from 
all  others  of  the  Adephagous  series  are  of  such  an  important  nature  that 
he  insisted  on  maintaining  the  view  originally  expressed  by  Dr.  Leconte 
of  the  position  of  Amphizoa. 

Attention  was  also  directed  to  two  finished  plates  illustrating  genera  of 
the  Serricorn  series,  the  text  being  nearly  completed  by  our  printer.

[Paper  No.  3.] 

The  Live  Oak  Root  Gall. 

This  interesting  gall  was  discovered  the  latter  part  of  March.  A  work- 
man ploughing  around  a  live  oak,  Quercus  virens,  noticed  some  curious 
galls  on  the  roots  and  called  my  attention  to  them.  A  careful  search 
soon  revealed  great  quantities,  always  on  the  small  rootlets  running  along 
just  beneath  the  surface.  On  pulling  up  these  roots,  I  discovered  a  series 
of  gall  clusters  every  four  or  five  inches  apart,  and  have  bred  from  them 
nearly  two  hundred  specimens,  %  and  9  Ai^s.  These  are  the  first 
authentic  oak  root  galls  discovered  in  the  United  States. 

BiorrMza  niger^  Fitch,  discovered  on  snow  probably  produces  galls 
on  oak  roots  ;  but  the  galls  have  not  yet  been  found.  < 


ENTOMOLOGICAL   SECTION.  XXV 

As  my  species  presents  characters  widely  diiFerent  from  any  cynipidous 
genera  known,  I  propose  to  erect  a  new  genus  for  its  reception.  Like 
Biorrhiza  niger,  it  secretes,  when  handled,  a  strong  waspy  odor.

l>ryorIiizoxeniis  floridaniis  n.  sp. 

Galls. —  Clusters  of  irregular  somewhat  wedge-shaped,  soft,  fleshy 
galls,  of  the  consistency  of  a  potato,  surrounding  the  rootlets  of  Quercus 
vlrens^  brittle  and  easily  detached,  varying  in  length  from  one-half  to 
three-fourths  of  an  inch  ;  externally  rough,  irregular,  and  of  a  yellowish 
color ;  internally  composed  of  numerous  cells  one  above  another,  and 
separated  by  thick  fleshy  partitions. 

Gall-Fly. —  9- — Length  .20  inch.  Slender;  bright  shining  brownish-yellow; 
head  finely  punctate,  eyes,  tips  of  mandibles  and  ocelli  black;  antennte  brown, 
basal  joint  paler;  thorax  convex,  smooth  and  shining,  two  deep  longitudinal

tarsi  less  densely  hii-sute,  black  and  with  the  tibial  spines  less  strongly  developed 
than  in  J ;  abdomen  elongate-ovate,  smooth  and  shining,  second  segment  occupy- 
ing half  the  surface,  other  segments  gradually  decreasing  in  size;  otherwise 
as  in   9  • 

Described  from  nearly  two  hundred  bred  specimens.  The  fleshy  galls, 
when  dry,  are  almost  unrecognizable  from  the  shrinkage  in  drying. 

The  Grape-producing  Cynips. 

This  is  a  very  remarkable  Cynips  producing  galls  on  the  under  surface 
of  the  leaves  of  Quercus  laurifolia,  which  very  much  resemble  small 
white  grapes.     They  make  their  appearance  early  in  April,  but  the  flies 
do  not  escape  until  the  middle  of  May. 
Cynips  q.  raceinaria  n.  sp. 

Galls. — Spherical,  crisp,  sour  and  succulent,  attached  to  the  under 
surface  of  the  leaves,  in  size  and  color  resembling  a  small  white  grape 
and  in  consistency  not  unlike  a  green  gooseberry,  with  a  single  reddish 
kernel  in  the  centre.     Diameter  .35  to  .40  inch 

Gall-Fly. —  9- — Length  .16  to  .17  inch.  Black;  head  rather  small,  deeply 
rugoso-punctate,  vertex  free  from  pubescence,  a  tuft  of  long  pubescence  back  of 
eyes,  face  very  slightly  pubescent;  antennte  14-jointed,  black  and  short,  only 
reaching  to  tip  of  scutellum,  third  joint  longest,  fourth  to  eighth  subequal,  the 
others  equal,  terminal  slightly  longer  than  penultimate;  thorax  deeply  coarsely 
and  irregularly  punctate,  almost  free  from  pubescence,  requiring  a  high  power  to 
detect  any ;  pleurse  less  deeply  and  coarsely  punctate ;  abdomen  large,  black  and 
shining,  apical  half  of  second  segment,  and  all  the  other  segments  excepting  at 
base,  finely  and  densely  punctate,  a  few  hairs  on  second  segment,  ventral  sheath 
very  long;  legs  reddish-brown,  pubescent,  coxse  and  trochanters  black,  apical 
spurs  on  all  legs;  wings  smoky  or  brownish-black,  apices  slightly  paler,  veins 
black,  areolet  closed,  radial  area  open,  rather  narrow. 

Described  from  numerous  bred  specimens  which  hatched  in  May. 
No  males. 

The  only  other  grape-like  gall  known  to  me  is  Cynips  q.  sculptus 
Bassett,  described  in  Proc.  Entom.  Soc.  Phila.  1863,  p.  324.  The 
present  species  is  at  once  distinguished  from  it  by  its  smaller  size,  short 
14-jointed  antenna3,  the  difiierence  in  shape  of  joints,  color  of  legs  and 
by  the  punctation  of  abdomen. 

Cynips  q.  sculptus  is  9  .20  inch,  antennte  13-jointed  very  long,  legs 
honey  yellow,  abdomen  entire  surface  microscopically  punctate.  It  was 
found  by  Mr.  Bassett  on  Quercus  rubra. 

The  Spine-bearing  Potato  Gall. 

Another  potato  gall,  varying  greatly  in  size,  found  on  the  terminal 

twigs   of  Quercus  laurifolia.      It  very   much   resembles  the  live  oak 

potato  gall,  Cynips  q.  batatoides  nob. ;  but  is  easily  distinguished  from 

it  and  all  others  by  the  spiny,  succulent  tubes  which  issue  from  the 


ENTOMOLOGICAL   SECTION.  XXVU 

fleshy  part  of  the  gall.  These  often  become  quite  large,  but  are 
generally  eaten  by  birds,  or  become  broken  ofi"  by  the  swaying  of  the 
branch  in  the  storms  and  winds.  As  they  mature  the  galls  become 
irregular,  crack  and  turn  black  with  age,  ultimately  killing  the  twig 
upon  which  they  are  situated.  At  this  stage  there  is  a  small  black  ant 
that  gnaws  into  and  makes  it  the  abode  of  her  countless  progeny. 

Cyiiips  q.  clavigera  n.  sp. 

Galls. — Abrupt,  irregular,  woody,  tuber-like  swellings,  varying  greatly 
in  size,  from  a  half  to  an  inch  and  a  quarter  long  by  almost  the  same  in 
width,  attached  to  the  terminal  twigs  and  branches;  externally  (at  the 
beginning  of  the  season),  it  is  smooth  and  resembles  very  much  the  gall 
of  Cynips  q  hatatoides,  but  later  in  the  season  it  becomes  rough  with 
deep  fissures,  through  which  issue  spiny,  succulent  tubes,  which  secrete 
a  sticky  honey-like  substance ;  internally,  at  first  it  is  white  and  soft  but 
becomes  brown  and  hard  with  age ;  the  tubes  are  thickened  at  base  in 
the  centre  of  which  the  larva  resides. 

Gail-Fly. —  9  • — Length  .08  inch.  Reddish-brown ;  head  and  thorax  very  finely 
punctate,  face  slightly  aciculate,  converging  towards  mouth;  antennje  long,  15- 
jointed,  first  joint  as  long  or  almost  as  long  as  third,  second  globular,  slightly 
longer  than  wide,  joints  four  to  eight  subequal,  from  nine  to  fourteen  short,  equal, 
apical  smallest;  thorax,  parapsidal  grooves  distinct,  two  longitudinal  furrows 
converging  towards  scutellum  ;  pleurse  punctate ;  scutellura  finely  rugoso-punctate 
and  bifoveolate ;  abdomen  brownish-black  on  dorsum,  reddish-brown  beneath, 
smooth  and  shining  and  of  a  very  peculiar  shape;  viewed  from  above  it  is  as 
usual,  but  viewed  sideways  it  is  much  deeper  than  long,  with  the  ovipositor  pro- 
jecting at  an  angle  of  forty-five  degrees;  with  a  quarter  inch  glass  the  segments 
show  that  they  are  finely  microscopically  punctate;  wings  hyaline,  veins  yel- 
lowish, areolet  closed,  the  closing  vein  being  faint  and  nearly  hyaline,  radial  vein 
and  subcostal  extend  to  costal  edge  but  the  subcostal  does  not  extend  along  the 
margin  to  radial  vein,  hence  is  open  ;  legs  reddish-brown. 

Described  from"  one  specimen  taken  from  gall  May  3d. 

The  Gone  Gall. 

A  black  or  brownish-black  conical  gall,  issuing  from  the  bud  axils 
of  the  larger  branches  of  Quercus  laurifolia  and  Q.  phellos,  was  dis- 
covered early  in  April.  They  present  a  very  anomalous  appearance  on 
the  branch. 

From  numerous  specimens  gathered  early  in  the  season,  I  have  bred 
many  parasites,  principally  Figifes,  but  no  Ci/nips,  and  my  description  is 
made  from  a  dried  specimen  obtained  by  opening  one  of  the  galls. 

Cynips  q.  coiiif'era  n.  sp. 

Galls. — -Hard,  conical,  black  or  brownish-black  galls,  less  than  half 
an  inch  or  more  long,  by  a  quarter  of  an  inch  or  more  in  diameter  at

to  ten  subequal,  the  following  equal,  apical  joint  slightly  longer  than  penultimate ; 
thorax :  parapsidal  grooves  distinct,  two  longitudinal  furrows,  pleurae  aeiculate ; 
scutellum  roundish,  elevated  posteriorly,  rugoso-ijunctate,  bifoveolate  with  the 
basal  and  posterior  margins  dark  brown ;  abdomen  smooth  and  shining  j  ovipositor 
slightly  exserted;  wings  hyaline,  veins  stout,  brownish,  areolet  almost  closed, 
radial  area  open ;  legs  brownish-yellow. 

The  Lemon-like  Gall  of  the  Willow  Oak. 
By  this  popular  name,  I  designate  another  gall  on  Qtiercus  j^hellos, 
yellow  in  color  and  not  unlike  a  lemon  in  shape. 

Cyiiips  q.  citriforinis  n.  sp. 

Gulls. — Globular,  smooth,  shining  yellowish  galls,  from  seven-eighths 
to  an  inch  in  length,  by  three-eighths  to  half  an  inch  in  diameter, 
attenuated  to  a  sharp  point  at  tip  and  with  a  single  kernel  in  the  centre, 
held  in  place  by  a  few  thin,  radiating,  spiculate  filaments. 

Gall-Fly. —  9  • — Length  .20  inch.  Robust,  head  and  thorax  brownish-black, 
deeply  and  coarsely  rugoso-punctate,  eyes  black,  cheeks  and  £ace  pubescent,  palpi

Studies  on   the   North  Ainericstu   C'IIAL.€ID1D.£.  with  «Ie- 
sci'iptioiis  of  New  Species  froiu  Florida. 

BY    WILLIAM    H.    ASH  MEAD. 

Jacksonville,  Florida. 
[Pai-ku  No.  1.] 

The  following  is  the  beginning  of  a  series  of  papers  on  our  North 
American  Chalcididse — a  large  and  extensive  family  of  parasitic  hymen- 
opterous  insects  comprising  the  minute  forms,  which  are,  however, 
readily  distinguished  from  all  others  by  their  elbowed  antennae  and 
almost  veinless  wings. 

Although  they  are  among  the  most  interesting  and  brilliantly  colored 
of  the  order  Hymenoptera ;  yet  up  to  the  present  time,  when  we  take 
into  consideration  the  extent  of  our  continent,  comparatively  few  species 
have  been  described. 

These  studies  are  not  intended  to  bo  exhau.'^tive  but  merely  pre- 
liminary— i.  e.,  an  attempt  to  ascertain  and  group  together  all  that  has 
been  written  on  the  subject,  and  at  the  same  time  describe  the  new  forms 
brought  under  my  observation  in  Florida. 

The  species  belonging  to  the  genera  Leucospis,  Smin-a  and  (^halcis, 
have  been  exhaustively  treated  by  our  well  known  Hymenopterist 
Mr.  E.  T.  Cresson,  in  a  memoir  published  in  Vol.  IV,  Trans.  Amer. 
Ent.  Soc.  1872.  I  have,  therefore,  only  to  record  the  new  species 
since  its  publication.

of  the  outer  costal  edge  black,  other  veins  brownish  ;  legs  yellowish,  anterior  and 
middle  femora  infuscated  in  middle,  the  thick  oval  posterior  femora  yellowish- 
brown,  a  broad  dark  medio  band  occupying  one-third  or  more  of  the  surface,  the 
band  is  also  extended  over  on  to  the  tibire  as  may  be  seen  when  these  are  drawn 
up  into  the  femoral  groove,  the  latter  armed  with  about  eighteen  small  but  regular 
teeth,  tarsi  pale  yellowish,  ungues  black. 

Captured  on  rose  galls.  I  do  not  think  it  parasitic  on  the  galls ; 
it  was  probably  attracted  there  by  some  larvte.

This  species  I  have  bred  from  the  cynipidous  oak  gall  ('.  q.  riigosa 
Ashmead.  It  agrees  very  well  with  Walsh's  description  excepting  its 
larger  size  and  the  whole  abdomen  being  black.  He  says  :  "  $  with  the 
bng  medial  or  fifth  joint  always  rufous  and  the  fourth  generally  piceous." 
I  am  therefore  in  doubt  whether  the  determination  is  correct.

Walsh  was  unable  to  identify  this  species  and  seemed  to  think  the 
"laws  of  coloration  forbid  its  existence."     Neither  Walsh's  want  of  suc- 
cess in  finding  it,  nor  are  the  laws  of  coloration  sufficiently  demonstrated, 
to  warrant  its  rejection.

This  species  in  color  and  markings  resembles  C.  c<.rulea  very  much 
and  for  a  long  time  I  was  of  the  opinion  that  they  were  identical. 
A  more  careful  examination  soon  dispelled  the  illusion.  It  may  be 
easily  distinguished  by  a  more  slender  form,  by  punctation  being  more 
coarsely  punctured  than  ccerulea,  by  the  face  being  covered  by  a  dense 
silky  pubescence,  by  the  antenna  being  brownish,  scape  a-eddish  by 
the  much  Jonger  ovipositor,  and  by  the  yellowish-red  pubescent  legs. 
In  coerulea  the  legs  are  not  pubescent. 

The  %  is  .IG  inch  in  length,  and  is  difficult  to  distinguish  from  ^  ot 
ccerulea.  It  may  be  distinguished  however  by  the  scutellum  bemg 
divided  in  the  middle  by  a  tran.sverse  suture,  by  all  the  femora  being 
blue  exceptins  at  tips  and  by  a  darker  abdomen.

ninth  joint;  thorax  stout,  rounded  in  front,  convex  and  narrowing  posteriorly, 
pubescent;  eollare  not  visible,  parapsidal  grooves  distinct,  a  distinct  medio-longi- 
tudinal  groove  on  praescutellum ;  scutellum  moderately  large,  roundish ;  pleurae 
margined  around  the  edge  with  coarse  punctures;  abdomen  small,  fusiform,  black, 
smooth  and  shining;  with  a  distinct  but  short  peduncle ;  wings  hyaline,  no  sub- 
costal vein,  stigma  same  as  in  9,  the  stigmal  branch  not  quite  as  long  as  in  J: 
legs  brown,  posterior  femora  black,  tibiae  yellowish. 

This  unicjue  and  interesting  little  species  is  the  first  of  the  genus 
discovered  in  America. 

Described  from  one  %  and  one  9  bred  in  March,  from  the  pine 
aphis  L'irhnus  anstru/i  A.shmead.  This  pine  aphis  suifers  from  the 
attacks  of  many  internal  foes;  besides  the  above  I  have  bred  three 
other  chalcids  and  two  ichneumon  flies,  which  will  be  described  in 
some  future  paper. 

October  U.  1881. 
Director  Dr.  LeConte  in  the  chair. 
The  Publication  Committee  announced  the  completion  of  the  Trans- 
actions of  the  Americau  Entomological  Society  to  page  148. 

In  behalf  of  Mr.  Ashmead,  Dr.  Horn  presented  types  of  nearly  all 
the  species  described  in  the  paper  jjresented  at  the  last  meeting,  for  the 
cabinet  of  the  American  Entomological  Society. 

Dr.  McCook  exhibiti'd  some  small  Hymenoptera  hatched  from  the 
nests  of  Mud-Wasps.  He  also  placc^d  bc^fore  the  meeting  the  nests  and 
cocoons  of  some  sjtiders.  showing  the  means  made  use  of  for  their 
protection  and  concealment. 

Dr.  Horn  exhibited  a  new  Ci/chrus  from  Washington  Territory,  be- 
longing to  the  .sub-genus  Sphseroclerm,  this  being  the  first  known 
occurrence  of  the  latter  west  of  the  Mississippi. 

A  female  Xenorhipis  was  also  shown.  This  has  the  antennjie  not 
very  different  from  Melanophila  or  Ayrilus  while  the  male  antennae 
are  flabellate. 

Dr.  LeConte  gave  his  views  regarding  the  dispersion  of  Coleoptera 
in  times  following  the  glacial  epoch.  At  the  time  when  the  present 
circampolar  i-egions  were  much  warmer  than  now  and  the  continents 
probably  less  separated  or  even  joined,  the  fauna  was  perhaps  the  same 
in  the  entire  region.  The  glacial  invasion  extended  .farther  south  in 
the  Atlantic  region  than  in  the  Pacific,  obliterating  in  great  part  the 
Coleoptera  of  this  side  of  the  continent  while  the  Pacific  slope  was 
less  disturbed.     Consequently  the  species  of  the  latter  region  being  the 


XXXVl  MONTHLY    PROCEEDINGS 

descendants  of  the  circumpolar  fauna,  a  notable  resemblance  is  observed 
with,  their  descendants  in  the  European  fauna.  Our  Atlantic  region  was 
probably  replenished  by  an  invasion  of  species  from  the  south. 

Dr.  McCook  spoke  of  the  effect  of  the  cold  of  last  winter  in  extermi- 
nating the  spiders  in  various  neighborhoods,  notably  near  Washington. 

Dr.  LeConte  read  the  following  notes  on  the  habits  and  localities 
of  Coleoptera. 

Cicindela  pamphUa. — Corpus  Christi.  Texas;   (Mische). 

ChJsenius  Chaudoiri. — Lee  Co.,  Texas;  (Mische).

Fhytonomns  punctatus. — This  ct)mmon  Euro})ean  species  has  been 
noted  by  Mr.  Eiley  as  depredating  on  clover,  in  Yates  Co.,  N.  Y. 
P.  opimus  Lee,  founded  on  an  old  and  someAvhat  rubbed  specilnen  is 
referable  to  the  same  species,  and  shows  that  it  is  not  a  recent  importa- 
tion to  this  country.  The  specimen  in  (jue.stiou  was  given  me  by 
Dr.  Melsheimer  about  twenty-five  or  thirty  years  ago  and  was  then  old. 
A  similar  specimen  was  not  long  afterwards  sent  to  me  from  Canada. 
Some  peculiar  circumstances  have  probably  in  this,  as  in  many  other 
instances  already  recorded,  favored  the  development  of  this  insect  in 
Yates  Co.  to  i*uch  an  extent  as  to  make  it  injurious.

on  tegulse,  two  beneath,  another  on  scutellum  and  postscutellum,  coxse  beneath, 
and  sometimes  a  spot  on  eacih  side  of  abdominal  segments  3 — 5,  white  or  yellowish- 
white;  all  the  femora  and  tibise  beneath  lemon-yellow;  tarsi  fulvo-testaceous, 
except  the  posterior  pair  at  base;  the  face,  cheeks,  thorax  beneath  and  metathorax 
with  a  silvery  sericeous  pile  ;  sides  of  clypeus  generally  stained  with  brown;  first

beneath  mostly  black,  apex  beneath  with  a  tuft  of  yellowish  hair.  Length 
..3(1— .40  inch. 

Hah. — Montana,  (Morrison).  Easily  recognized  by  the  ferruginous 
abdomen,  the  first  segment  of  which  is  not  nodose  at  apex  above  as  in 
rujinodus,  which  it  much  resembles  in  form  and  sculpture.
