.4  iiioiiograpli  of  the  species  of  CRYPTOHYPNUS  of 
Boreal  America. 

BY  GEORGE  H.  HORN,  M.  D. 

In  the  printed  and  other  comments  which  were  made  on  Dr. 
Hamilton’s  paper  on  the  distribution  of  many  species  in  common 
in  the  Arctic  regions  of  both  continents,  my  attention  happened  to 
be  drawn  especially  to  this  genus  from  the  fact  that  several  forms 
had  just  appeared  which  seemed  to  be  identical  with  those  of  Europe, 
and  which  had  not,  as  yet,  appeared  in  our  lists.  These  were  made 
the  subject  of  a short  note,  in  “ Entomological  News,”  which  closer 
study  has  shown  me  to  be  inaccurate  in  many  of  its  statements,  due 
in  part  to  the  lack  of  types,  and  as  much  to  important  omissions  of 
details  in  the  best  European  descriptions.  The  subsequent  pages 
will  show  that  several  of  our  forms  are  parallel  with  those  of  Europe, 
in  fact  deceptively  resembling  them,  but  are  readily  separated  by 
excellent  structural  characters  hitherto  unobserved. 

The  number  of  species  of  Cryptohypnus  known  being  less  than 
one  hundred,  has  not  made  it  unwieldy  or  difficult  to  handle,  conse- 
quently but  little  attempt  has  been  made  to  subdivide  it.  C.  G. 
Thomson,  in  his  Skand.  Col.  vi,  restricts  the  name  Cryptohypnus  to 
those  species  which  have  the  prosternal  sutures  straight  and  Negas- 
trius  to  those  with  the  sutures  arcuate,  although  he  seems  to  place

greater  reliance  on  other  cliaracters  which  have  far  less  value  in  a 
larger  number  of  species.  He  again  subdivides  Negastrius,  sepa- 
rating those  s})ecies  as  Zorochrus  which  have  the  prosternal  sutures 
double  and  excavate.  If  any  division  of  Cryptohypnus  be  thought 
necessary,  that  based  on  the  form  of  the  prosternal  sutures  appears 
to  be  the  only  one  desirable,  from  the  fact  that,  between  the  two 
forms,  the  sharpest  line  of  demarcation  is  observed. 

The  existence  of  the  double  grooved  sutures  in  a group  of  small 
species  was  first  observed  by  Thomson,  but  cannot  be  used  for  generic 
separation  as  it  would  remove  certain  species  from  that  close  approxi- 
mation in  which  they  should  be  placed.  It  has  also  been  observed 
in  our  species  of  that  series  that  the  groove  is  far  more  distinctly 
defined  in  the  female  than  in  the  male.  It  is  in  this  group  that  very 
notable  sexual  peculiarities  exist  in  the  form  of  tubercles  on  the  first 
or  first  two  ventral  segments  in  the  males  of  Melsheimeri  and  caurimis 
respectively,  or  in  a small  ])ubescent  spot  at  the  middle  of  the  second 
ventral  in  the  female  of  c/radarms.  In  quadriguttatm  (tetragraphii^) 
and  dermestoides  of  Europe,  the  anterior  tibiae  are  much  broader  in 
the  male  than  in  the  female.  These,  too,  have  an  elevation  or  tu- 
bercle on  the  first  ventral  segment  of  the  male  which  seems  to  have 
escaped  the  notice  of  European  students. 

Another  sexual  character  has  been  observed  in  the  two  species 
with  non-striate  elytra.  In  the  centre  of  the  prosternum  of  the  male 
is  a small,  densely  punctured  spot,  bearing,  in  well-preserved  speci- 
mens, a short  brush  of  hair. 

One  species,  Httoralis,  is  notable  in  having  much  shorter  legs  than 
normal,  the  tibice  beset  with  short,  stiff,  bristle-like  hairs,  after  the 
manner  of  many  arenicolous  species.  The  tibial  spurs  are  also  better 
developed.  In  the  species  with  the  curved  prosternal  sutures  the 
spurs  are  far  less  distinct  than  in  those  with  straight  sutures. 

It  will  be  observed  also  that  the  terminal  joint  of  the  maxillary 
palpus  varies  in  form,  but  without  that  degree  of  difference  enabling 
the  character  to  be  used  for  systematic  purposes.  Illustrations  will 
be  found  on  the  plate,  to  which  the  reader  is  referred. 

The  species  known  to  me  seem  to  divide  very  naturally  into  groups, 
and  it  is  proposed  so  to  treat  them  to  avoid  the  use  of  a long  analytical 
table. 

They  are,  therefore,  divided  as  follows ; 

Prosternal  sutures  straight,  parallel,  or  very  little  convergent  posteriorly 2. 

Prosternal  sutures  arcuate  and  very  evidently  convergent  posteriorly 3.

2.  — Tibife  stouter  than  usual,  the  outer  side  beset  with  short  spinules,  the  spurs 

very  distinct Group  LITTORALIS. 

Tibiffi  slender,  not  spinulose  externally,  the  spurs  usually  very  small  and 
indistinct. 

Depressed  opaque  species,  thorax  coarsely  and  closely  punctate. 

Group  SQUALIDUS. 

More  or  less  convex  and  shining,  thorax  variably  punctate,  but  never 
opaque,  the  median  line  more  or  less  impressed. 

Hind  angles  of  thorax  slender  and  divergent,  the  basal  incisure  well 
marked;  surface  not  distinctly  pubescent.. -Group  HYPERBOREUS. 

Hind  angles  of  thorax  stouter,  scarcely  at  all  divergent,  basal  incisures 
feeble;  surface  pubescent Group  ABBREVIATUS. 

3. — Elytra  with  the  striae  entirely,  or  in  great  part  obliterated  ; in  the  latter 

case,  those  near  the  suture  alone  evident Group  PECTORALIS. 

Elytra  with  all  the  striae  entire 4. 

4. — Depressed  species,  dorsum  quite  flat,  surface  opaque,  densely  punctulate 

and  pubescent;  hind  angles  of  thorax  with  short  carina. 

Group  STRIATULUS. 

Convex  species. 

Thorax  coarsely  granulate,  usually  with  a smooth  elevated  median  line. 

/ Group  CHORIS. 

Thorax  unequally  sculptured,  either  subasperate  or  more  densely,  coarsely 
punctate  near  apex,  posteriorly  smoother,  median  line  usually  smooth 

Group  MELSHEIMERI. 

Thorax  equally  punctate,  either  sparsely  or  moderately  closely ; elytra 
ornate Group  PERPLEXUS. 

The  groups  which  follow  are  arranged  in  a manner  to  show  what 
seems  to  be  a natural  sequence  based  on  facies. 

In  conclusion,  I wish  to  acknowledge  my  indebtedness  to  Dr. 
Hamilton  and  Mr.  Ulke  for  the  loan  and  gift  of  specimens,  and  to 
Mr.  Blanchard  for  first  having  called  my  attention  to  the  pubescent 
spot  in  the  abdomen  of  gradarms,  thereby  suggesting  a new  line  of 
investigation  which  has  resulted  profitably. 

Group  LITTORALIS. 

Prosternal  sutures  straight,  very  nearly  parallel.  Maxillary  palpi 
moderate  in  length,  the  last  joint  elongate  oval,  obliquely  truncate 
at  apex.  Tibiae  shorter  than  usual,  the  outer  edge  beset  with  short 
spinules,  the  terminal  spurs  well  marked.  Form  robust,  body  ap- 
terous. 

This  group  contains  but  one  species  so  unlike  those  which  follow, 
as  to  lead  to  the  supposition  that  it  should  be  more  completely  sepa- 
rated. There  are,  however,  no  differences  of  sufficient  importance 
to  warrant  generic  separation.

littorali!4  Escb. — Form  robust,  convex,  brownish  piceous  or  darker  fer- 
ruginous, scarcely  sbining.  sides  of  tborax  (more  broadly  beneath)  and  elytra, 
antenme  and  legs  yellowish  testaceous;  antennae  rather  stout,  joints  6-10  as 
broad  as  long,  eleventh  oval ; bead  sparsely,  rather  coarsely  punctate ; thorax 
broader  at  middle  than  long,  sides  arcuate,  sinuate  in  front  of  the  hind  angles, 
which  are  acute  and  feebly  divergent,  the  carina  short,  hut  well  marked  ; disc 
sparsely  punctate,  basal  margin  without  trace  of  incisure:  elytra  oval,  humeri 
obliquely  rounded,  disc  rather  deeply  striate,  strise,  not  punctate,  intervals  con- 
vex, sparsely  punctate  near  the  base,  gradually  becoming  granulate  toward  the 
apex ; body  beneath  piceous,  except  the  flanks  of  the  prothorax,  these  finely 
punctate  externally,  more  coarsely  near  the  inargin  ; under  surface  punctate, 
hut  not  closely,  except  on  the  last  ventral  segment,  which  is  quite  rugose. 
Length  8 — 11.5  mm. ; .32 — .46  ineh. 

In  well  preserved  specimens  the  surface  above  and  beneath  is 
sparsely  fulvo-pubescent.  A variety  entirely  yellowish  is  mentioned 
by  Mannerheim  and  Candeze,  not  the  result  of  immaturity,  as  might 
be  suspected,  but  truly  varietal,  as  has  been  observed  in  many  species 
living  along  the  sea-coast. 

Seems  to  be  abundant  on  the  Alaskan  sea-coast. 

Group  HYPERBOREUS. 

Prosternal  sutures  straight,  very  slightly  convergent  posteriorly. 
Legs  slender,  tibial  spurs  small.  Maxillary  palpi  not  prominent, 
the  last  joint  triangular,  as  in  the  squalidus  group.  Thorax  smooth, 
sparsely  punctate,  median  line  more  or  less  impressed,  the  basal  in- 
cisures distinct,  hind  angles  long,  slender  and  divergent.  Surface 
nearly,  or  quite  glabrous,  body  winged. 

This  group  contains  but  three  species,  as  far  as  known  to  me,  espe- 
cially notable  by  their  oblong,  feebly  convex  form,  nearly  glabrous 
surface,  subsulcate  thorax  with  slender  hind  angles. 

The  species  are  separated  as  follows : 


AntenuiB  entirely  ferruginous. 

Anteimse  rather  slender,  the  joints  longer  than  wide g;raii(licollis. 

Antenna  stouter,  joints  triangular,  as  wide  as  long liyperboretis. 

Antenna  piceous,  except  at  base,  the  joints  longer  than  wide. 

Elytral  intervals  fiat Saiiboriii. 

Elytral  intervals  convex barbatiis. 


These  inhabit  the  more  northern  or  elevated  regions  of  our  country, 
one  of  them  {hyperhorens)  having  a circum-polar  distribution  in  both 
hemispheres. 

C’.  graiKlicollis  Lee. — Oblong,  moderately  convex,  piceous  shining,  with 
faint  metallic  lustre,  elytra  paler  than  the  thorax;  surface  scarcely  pul)escent ; 
antcTina  ferruginous,  joints  all  longer  than  wide;  front  fiat,  coarsely  not  closely

punctate ; thorax  distinctly  longer  than  wide,  sides  scarcely  arcuate,  hind  angles 
very  slightly  divergent,  distinctly  carinate,  carina  short,  disc  moderately  convex, 
median  line  vaguely  impressed  posteriorly;  surface  sparsely  punctate,  a little 
more  closely  in  front  and  near  the  front  angles;  elytra  a little  wider  than  the 
prothorax  at  their  middle,  humeri  obtusely  rounded  ; disc  moderately  convex, 
rather  deeply  striate,  strim  punctate,  intervals  slightly  convex,  sparsely  punc- 
tate ; prosternum  moderately  coarsely,  but  sparsely  punctate,  the  lobe  moderately 
prominent,  arcuate  in  front,  limited  behind  by  a feeble  transverse  line,  propleura; 
moderately  closely  coarsely  punctate,  with  finer  punctures  between,  not  opaque; 
metasternum  moderately  closely  punctate,  punctuation  coarse  and  fine  inter- 
mixed ; abdomen  similarly  punctate,  the  last  segment  more  coarsely;  legs  rufo- 
testaceous  ; entire  body  beneath  paler  than  above.  Length  9 mm. ; .36  inch. 

A much  more  robust  species  than  any  of  this  group  and  with  the 
thorax  of  larger  area  relative  to  the  elytra. 

A specimen  in  the  LeConte  cabinet,  which  I have  no  doubt  is  the 
male,  has  a rather  more  slender  form,  the  sides  of  thorax  sinuate  in 
front  of  the  hind  angles,  which  are  consequently  more  slender  and 
divergent.  Its  color  is  slightly  darker.  These  differences,  in  view 
of  the  opposite  sex  of  the  specimens,  seem  purely  sexual  and  not 
specific. 

Occurs  in  Canada  and  Oregon,  S . 

C.  hyperboreus  Gyll. — Moderately  elongate,  depressed,  piceous  brown, 
moderately  shining,  antennsE  and  legs  ferruginous;  surface  very  sparsely  pubes- 
cent ; antennse  short,  joints  4-10  as  wide  as  long ; head  slightly  convex  at  middle, 
sparsely  punctate;  thorax  as  broad  as  long  9 > or  a little  longer  % ; scarcely 
narrowed  in  front,  sides  regularly  arcuate  in  front  of  the  hind  angles  which  are 
slender,  divergent,  and  with  a short  carina;  surface  shining,  sparsely  punctate, 
median  line  vaguely  impressed ; elytra  wider  than  the  thorax,  oblong  oval, 
widest  at  middle,  humeri  rounded,  disc  rather  depressed,  finely  striate,  strife 
indistinctly  punctate  at  middle,  intervals  flat,  sparsely  punctate;  prosternum 
sparsely  punctate  at  middle,  densely  and  finely  at  the  sides,  the  lobe  moderately 
prominent,  arcuate  in  front,  limited  behind  by  a transverse  impression,  propleurse 
densely  finely  punctate,  with  coarser  punctures  intermixed,  rather  opaque,  dis- 
tinctly pubescent;  metasteruum  sparsely  punctate;  abdomen  closely  punctate 
with  coarse  and  fine  punctures  intermixed,  and  with  fine  brownish  pubescence. 
Length  6.5 — 8 mm. ; .26 — .32  inch. 

This  species  is  very  nearly  as  depressed  as  those  of  the  squalidus 
group.  It  is  paler  in  color  than  Sanborni,  and  without  the  faint 
metallic  lustre  of  that  species  and  differing  also  in  the  color  of  the 
antennae. 

This  species  is  known  from  Lapland,  Siberia,  Kamtschatka,  and 
on  our  own  continent  in  Alaska. 

C’.  $$anborui  Horn. — Oblong,  moderately  convex,  piceous  black,  moder- 
ately shining,  sometimes  with  a faint  bronze  surface  lustre,  very  slightly  pubes- 
cent; autennfe  slender,  feebly  serrate,  joints  all  longer  than  wide,  iiasal  joints

nifo-testaceons,  the  outer  joints  piceous  ; head  si>arsely  punctate;  thorax  longer 
than  wide,  not  narrowed  in  front,  widest  at  middle,  sides  feebly  arcuate,  sinuate 
in  front  of  the  hind  angles,  which  are  slender,  acute,  distinctly  divergent  and 
carinate  above,  di,sc  moderately  curved,  the  median  line  vaguely  impressed  from 
base  to  apex,  basal  incisures  distinct;  surface  sparsely  finely  punctate:  elytra 
oblong  oval,  widest  behind  the  middle,  humeri  oblique,  disc  striate,  strise  dis- 
tinctly punctured,  intervals  flat,  sparsely  punctate,  but  more  coarsely  than  the 
thorax  ; jn-osternal  lobe  moderately  prominent,  the  border  distinctly  beaded,  a 
transverse  impression  posteriorly,  coarsely  punctate  in  front,  more  finely  and 
sparsely  toward  apex,  punctuation  at  sides  denser  and  intermixed,  propleurte 
rather  densely  punctate  and  more  opaque,  with  coarser  and  fine  punctures  inter- 
mixed ; epipleurre  jiale;  metasternum  and  abdomen  rather  densely  punctulate 
with  coarser  punctures  intermixed  ; legs  rufo-testaceous,  tarsi  darker.  Length 
5,5 — 7 mm.;  .22 — .28  inch. 

The  hind  angles  of  the  thorax  at  tip,  the  epipleurae  of  the  elytra 
and  a narrow  border  of  the  under  side  of  thorax  are  usually  rufes- 
cent.  The  median  line  of  the  thorax,  although  feeble,  is  distinctly 
impressed  from  base  to  apex  ; all  the  strite  of  the  elytra  are  punctate. 

Occurs  in  the  White  Mountain  region  of  New  Hampshire,  where 
it  was  first  collected  by  Mr.  F.  G.  Sanborn,  and  since  by  Blanchard, 
Henshaw  and  others. 

barbatiis  Sahib. — Oblong,  moderately  convex,  piceous  black,  moderately 
shining,  sparsely  clothed  with  short,  inconspicuous,  brownish  pubescence;  an- 
tenn®  slender,  feebly  serrate,  piceous,  the  two  basal  joints  pale;  head  rather 
coarsely  punctate,  front  triangularly  flattened,  the  middle  of  the  triangle  elevated 
in  an  umbone;  thorax  longer  than  wide,  very  little  narrowed  in  front,  sides 
feebly  arcuate,  sinuate  in  front  of  the  hind  angles,  which  are  slender  and  slightly 
divergent,  carina  well  marked,  but  short;  disc  convex,  a median  impression 
reaching  the  base  and  very  nearly  the  apex  ; surface  moderately  coarsely  punc- 
tate in  front  and  at  sides,  smoother  at  middle  and  near  base;  elytra  oblong-oval, 
wider  slightly  behind  the  middle,  humeri  rounded,  disc  convex,  deeply  striate, 
strire  punctate,  intervals  convex,  moderately  closely  punctate;  prosternum  trans- 
versely Impressed,  rather  finely  punctate  behind  the  groove,  very  coarsely  in 
front,  the  lobe  moderately  prominent,  subtruncate;  propleurje  opaque,  slightly 
rugulose,  coarsely  sparsely  punctate;  epipleurte  pale ; abdomen  closely  punctate 
with  coarser  punctures  intermixed,  especially  near  the  sides;  legs  rufo-testace- 
ous, the  tarsi  piceous.  Length  6.5  mm. ; .26  inch. 

Very  close  to  Sanborni,  and  possibly  only  an  Arctic  form  of  it. 
The  pubescence  of  the  prosternal  lobe  seems  to  have  been  rather 
exaggerated  in  importance  and  extent,  as  all  the  species  of  the  pres- 
ent and  the  ahbreviatus  groups  have  a slight  pilosity  in  that  portion 
not  by  any  means  dense,  and  often  lost  by  abrasion. 

I owe  to  Dr.  Sahlberg  the  privilege  of  examining  a typical  speci- 
men. Occurs  in  the  vicinity  of  St.  Lawrence  Bay  extending  to  Port 
( 'larence  on  the  American  coast. 


NORTH  AMERICAN  COLEOPTERA. 


Group  ABBREVIATUS. 

Prosternal  sutures  straight,  nearly  parallel.  Maxillary  palpi 
moderate  in  length,  the  last  joint  triangular,  truncate  at  apex.  Legs 
not  long,  tibiie  not  spinulose  externally,  terminal  spurs  small.  Thorax 
with  median  line  more  or  less  impressed,  the  basal  incisures  feebly 
distinct,  hind  angles,  at  most,  but  little  everted,  the  carina  not  long. 
Surface  pubescent.  Body  winged. 

The  group  here  defined  is  with  difficulty  separated  by  description 
from  the  one  preceding,  but  the  more  convex  form,  pubescent  sur- 
face and  less  prominent  hind  angles  seem  sufficient. 

The  species  composing  the  group  occur  in  the  Arctic  regions  of 
both  continents,  extending  southward  in  the  more  northern  jiortions 
of  the  temperate  region,  and  along  the  mountain  ranges  in  the 
higher  altitudes  still  more  to  the  south. 

In  consequence  of  the  wide  distribution  of  the  species  and  the 
varied  climatic  influences  to  which  they  are  subjected,  a great  amount 
of  variation  has  been  produced.  This  range  of  distribution  is  from 
Labrador  on  the  east  to  northern  California  on  the  west,  and  in  the 
centre  of  the  continent  extending  southward  along  the  Rocky  Moun- 
tains to  New  Mexico,  thence  northward  in  every  part  of  British 
America  to  the  extreme  of  the  Alaskan  peninsula. 

In  the  great  quantity  of  material  examined  I have  not  been  able 
to  separate  more  than  three  species  : 

Scutellura  conspicuously  clothed  with  pale  pubescence,  that  of  the  elytra  some- 
what scale  like. 

Thorax  narrowed  in  front  in  its  apical  two-thirds,  sides  often  obtusely  suban- 
gulate  in  front  of  the  angular  sinuation ; elytra  with  a denser  spot  of 
pubescence  near  the  apex abbreTiatiis. 

Thorax  arcuate  near  the  apex  only,  the  sides  thence  nearly  straight ; elytra 

without  spot  of  denser  pubescence  near  tip impressicollis. 

Scutellum  sparsely  punctate  and  smooth,  with  scarcely  any  pubescence ; surface 
simply  sparsely  pubescent;  thorax  usually  very  sparsely  punctate,  the 
median  impression  very  indistinct lioctiirniis. 

C.  abbreviatus  Say. — Oblong,  moderately  convex,  piceous,  with  greenish 
bronze  surface  lustre,  sparsely  clothed  with  yellowish  cinereous  pubescence, 
somewhat  scaly  in  appearance,  forming  a conspicuous  elongate  space  on  the  ely- 
tral  declivity ; anteun®  feebly  serrate,  either  entirely  piceous,  or  with  the  basal 
joints  paler;  head  coarsely  not  closely  punctate,  the  frontal  margin  scarcely 
distinct  from  the  clypeal ; thorax  slightly  broader  than  long,  narrowed  in  front, 
sides  scarcely  arcuate,  but  obtusely  subangulate  behind  the  middle,  then  sinuate 
in  front  of  the  hind  angles,  these  acute  but  not  slender,  scarcely  divergent,  cari- 
nate ; disc  convex,  with  a median  impression  usually  extending  from  base  to 
apex  and  deeper  behind,  ba.sal  incisures  feeble,  surface  shining,  moderately

closely,  not  coarsely  punctate,  pubescence  somewhat  brownish  ; scutellum  rather 
densely  clothed  with  paler  yellowish  hairs  ^ elytra  a little  wider  than  the  thorax, 
widest  one-third  from  base,  humeri  rounded,  sides  arcuate,  gradually  narrowed 
in  apical  two-thirds,  but  obtuse  at  tip;  disc  convex,  striate;  strife  all  punctate, 
intervals  flat,  moderately  closely  and  finely  punctate;  body  beneath  piceous, 
finely  fulvo-pubescent,  epipleurm  usually  paler;  prosternum  sparsely  punctate  at 
middle,  at  sides  intermixed  and  finely  pubescent,  the  lobe  very  coarsely  punc- 
tate, moderately  prominent;  propleurm  o])aque,  finely  and  closely  punctate 
metiisteruum  moderately  closely  punctate  with  intermixed  punctures;  abdomen 
very  finely  and  closely  punctulate,  the  punctures  unequal;  legs  rufo-testaceous, 
the  femora  usually  darker.  Length  5.25—6.5  mm. ; .21 — .26  inch. 

'riiis  species  varies  in  color  from  piceous  black  to  brown,  the  elytra 
being  often  quite  pale.  It  may  also  vary  in  the  form  of  the  sides 
of  the  thorax,  the  subangulation  being  scarcely  evident  in  some 
(lacmtris),  but  the  thorax  is  always  narrowed  in  its  apical  two-thirds. 
The  strife  of  the  elytra  may  vary  in  sharpness,  and  their  punctures 
are  sometimes  scarcely  evident  on  the  disc. 

The  spot  of  pale  pubescence  near  the  apex  is  quite  characteristic, 
and  its  distinctness  is  not  due  to  the  abrasion  of  the  rest  of  the  sur- 
face. In  well  preserved  specimens  the  greater  portion  of  the  elytral 
pubescence  is  finer  and  more  brown,  consequently  less  distinct. 

No  special  sexual  characters  have  been  observed. 

(Occurs  from  Nova  Scotia  westward  through  Massachusetts,  New 
York,  Canada,  Hazleton,  Pa.  (Dietz),  to  Oregon  and  Alaska. 

C.  iiiiprcssicollis  Maun. — Oblong,  moderately  convex,  piceous  or  brown- 
ish, the  elytra  paler,  surface  slightly  feneous,  the  pubescence  sparse,  pale  brown- 
ish, rather  dense  and  fulvous  on  the  scutellum;  antenufe  feebly  serrate,  piceous. 
the  basal  joints  paler ; head  coarsely,  moderately  closely  punctate,  the  frontal 
margin  scarcely  elevated  ; thorax  scarcely  wider  than  long,  sides  nearly  straight, 
arcuately  narrowed  near  the  front,  a faint  trace  of  a sinuation  near  the  ungles, 
these  acute,  scarcely  at  all  divergent;  the  carina  feeble,  basal  incisures  distinct: 
disc  convex,  the  median  channel  distinct  from  base  to  apex  ; surface  moderately 
closely  punctate  and  (for  this  group)  rather  coarsely,  pubescence  fulvous  ; scu- 
tellum rather  closely  pubescent;  elytra  oblong-oval,  widest  near  the  middle,  the 
humeri  rounded;  disc  convex,  moderately  deeply  striate,  strife  all  punctate,  in- 
tervals flat,  rather  closely  punctate  and  posteriorly  slightly  asperately ; body 
beneath  piceous,  finely  pubescent  and  subopaque,  epipleurfe  paler;  prosternum 
sparsely  punctate,  more  coarsely  in  front  and  more  finely  at  the  sides ; propleurte 
opaque,  with  dense  fine  punctures,  with  coarser  intermixed  ; metasternum  finely 
indistinctly  punctate,  punctuation  double;  abdomen  densely  finely  punctate, 
with  coarser  punctures  intermixed  at  the  sides;  legs  rufo-testaceous.  femora 
darker.  Length  5 — 6 mm. ; .20 — .24  inch. 

This  species  superficially  resembles  abbreviatus,  but  the  form  of  the 
thorax  and  the  absence  of  the  spot  of  pubescence  near  the  apex  will

distinguish  it.  It  will  be  observed  in  abhreviatus  that  the  sides  of 
the  prosternum  have  a well  marked,  fine  silken  pubescence,  but  in 
this  there  is  no  such  character. 

In  one  of  the  specimens  before  me  the  elytra  are  paler  at  apex. 

While  I have  not  seen  a type  of  this  species  I am  quite  sure  that 
the  forms  examined  are  similar  to  the  unique  described  by  Manner- 
heim. 

Occurs  in  Alaska,  Oregon,  Hudson’s  Bay  Territory  and  Colorado 
(rare). 

C.  noctnrnus  Esch.— Oblong,  moderately  convex,  color  variable,  surface 
shilling  and  with  slight  aeneous  lustre,  sparsely  pubescent;  antennae  feebly  ser- 
rate, piceous,  the  basal  joints  often  paler;  head  coarsely,  not  closely  punctate, 
frontal  border  feebly  elevated  ; thorax  as  wide  as  long,  slightly  narrowed  in 
front,  sides  arcuate,  widest  at  middle,  a slight  sinuation  in  front  of  the  hind 
angles,  these  feebly  everted,  distinctly  carinate,  disc  moderately  convex,  median 
impression  feeble,  rarely  visible  in  front  of  the  middle;  surface  finely,  sparsely 
punctate;  elytra  oblong,  a little  wider  at  middle  than  the  thorax,  humeri  ob- 
tusely rounded,  striate,  striae  all  punctate,  intervals  flat,  or  slightly  convex  near 
the  base,  sparsely  finely  punctate;  scutellum  sparsely  punctate,  scarcely  at  all 
pubescent;  body  beneath  paler  than  above,  the  epipleurae  especially  so;  proster- 
num very  sparsely  punctate,  even  on  the  lobe,  sparsely  cinereo-pubescent  at  the 
sides,  the  lobe  moderately  prominent;  propleune  opaque,  closely  and  very  finely 
punctate  with  coarser  punctures  intermixed  ; metasternum  and  abdomen  with 
fine,  indistinct  punctures,  moderately  closely  placed,  with  slightly  larger  punc- 
tures intermixed;  legs  rufo-testaceous,  femora  always  darker.  Length  4 — 5.5 
mm. ; .16 — .22  inch. 

A variable  species,  widely  spread  over  the  northern  part  of  the 
continent,  and  with  an  unnecessary  amount  of  nomenclature,  the 
result  of  local  or  climatic  variation.  A few  varieties  seem  to  deserve 
mention. 

Var.  noetvrniis  Esch. — Larger  in  size,  piceous  black,  with  teneous 
surface  lustre.  The  double  punctuation  of  the  abdomen  scarcely 
evident,  except  at  the  sides.  The  hind  angles  of  the  thorax  are  not 
paler  than  the  disc.  Alaska,  Oregon,  California,  Nevada. 

Var.  lucidulus  Mann. — Smaller  than  nocturnus,  and  with  rather 
paler  surface  and  less  distinct  leneous  surface  lustre.  The  hind  an- 
gles of  the  thorax  are  usually  paler.  The  punctuation  of  the  under 
side  of  body  is  more  distinct,  and  its  double  character  more  evident. 
Of  this  form  fallax  Mann,  and  vestitus  Mann,  are  merely  individual 
variations.  Alaska,  Hudson’s  Bay,  New  Hampshire. 

Var.  bicolor  Esch.— Still  smaller,  the  hind  angles  of  the  thorax 
and  the  elytra  castaneous,  with  very  feeble  metallic  surface  lustre.

Punctuation  of  under  side  coarser,  its  double  character  very  evident. 
Of  this  scarificatus  and  limhatus  Mann,  are  feeble  varieties,  and  pi- 
cescens  Lee.  a synonym.  Alaska,  Oregon,  Hudson’s  Bay,  Dacota, 
Idaho,  Utah,  Montana,  Colorado,  New  Mexico,  Lake  Superior, 
Canada,  Labrador,  New  Hampshire. 

On  comparing  these  forms  with  abbreviatiis  and  impressicollis,  it 
will  be  observed  that  the  vestiture  is  finer  and  sparser,  the  scutellum 
nearly  glabrous.  The  thorax  is  always  more  sparsely  and  finely 
punctured.  The  form  is  also  less  convex  and  more  elongate. 

Candeze  states  (Mon.  iii,  p.  68)  that  riparius  Fab.  occurs  in  the 
polar  regions  of  our  continent.  I have  not  seen  any  specimens  that 
I am  willing  to  refer  to  that  species,  although  some  of  the  forms  of 
iuciduhis  have  the  dorsal  striie  so  feebly  punctured  that  they  might 
l)e  considered  smooth.  The  study  of  the  material  before  me  leads 
to  the  thought  that  all  the  species  from  the  Arctic  regions  of  both 
continents  need  a renewed  study  with  a larger  number  of  specimens 
than  seems  to  have  been  used. 

Group  SQUALIDUS. 

Prosternal  sutures  straight  and  parallel,  or  very  slightly  conver- 
gent posteriorly.  Maxillary  palpi  not  prominent,  the  terminal  joint 
triangular.  Legs  slender  and  moderately  long,  the  tibiae  not  spinu- 
lose,  the  terminal  spurs  small  and  inconspicuous.  Form  oblong, 
much  depressed  ; surface  opaque,  densely  punctured,  sparsely  pubes- 
cent. Body  distinctly  winged. 

This  group  is  represented  in  our  fauna  by  three  species,  and  a 
fourth  (depres-nis)  from  Siberia  should  probably  be  referred  here. 
The  flattened  form  and  opaque  surface  are  repeated  in  the  driaialus 
series,  but  these  have  the  strongly  arcuate  prosternal  sutures. 

The  three  species  are  as  follows ; 

Antennfe  and  legs  always  pale;  under  side  of  body  finely  pubescent  with  longer 

scale-like  hairs  sparsely  scattered sqiialitlus. 

Antennae  and  legs  piceous,  sometimes  the  tibije  are  pale;  vestiture  of  under  side 
uniform. 

Surface  very  opaque liiiiebris. 

Surface  slightly  aeneous plaiiatus. 

C’.  squalidus  Lee. — Oblong,  piceous  black,  opaque,  sparsely  clothed  with 
very  short  brownish  pubescence,  with  silken  yellow  sparsely  intermixed  : head 
coarsely,  not  closely  punctate : antennse  not  reaching  the  hind  angles  of  the 
thorax,  feebly  serrate,  joints  all  longer  than  wide,  the  eleventh  but  little  longer 
than  the  tenth ; thorax  longer  than  wide,  distinctly  narrowed  in  front,  sides 
regularly  arcuate,  sinuate  in  front  of  the  hind  angles,  these  slightly  divergent,

acute,  distinctly  carinate;  surface  moderately  closely,  but  not  densely  punctate^ 
very  evidently  lonfiitudinally  strigose ; disc  feebly  convex,  a distinct  basal  in- 
cisure opposite  the  fifth  stria;  elytra  slightly  wider  posteriorly  than  the  thorax, 
humeri  oblique,  sides  feebly  arcuate,  more  so  in  the  J ; disc  sub-depressed, 
striate,  striae  punctured,  more  coarsely  at  sides,  especially  near  the  humeri;  in- 
tervals flat,  rather  closely  punctate;  prosternal  lobe  long,  its  apex  with  a feebly 
beaded  edge  and  without  a transverse  impressed  line  posteriorly  ; surface  coarsely, 
not  closely  punctured,  feebly  pubescent,  propleurse  opaque,  coarsely  sparsely 
punctate  and  distinctly  pubescent;  metasternum  and  abdomen  sparsely  coarsely 
punctate,  with  extremely  fine  punctuation  closely  placed  between  them,  the 
vestiture  of  pale  brown,  fine  pubescence  with  intermixed  golden  scale-like  hairs. 
Length  7.5 — 8.5  mm. ; .30 — .34  inch. 

The  male  is  more  slender  and  parallel  than  the  female,  but  shows 
110  other  differences. 

Occurs  in  California  at  San  Jose  and  vicinity. 

C.  funebris  Cand.— Oblong,  depressed,  black,  opaque,  finely  pubescent; 
legs  piceous,  sometimes  with  the  tibise  paler;  head  coarsely  and  moderately 
closely  punctate;  antennae  piceous,  feebly  serrate,  the  joints  all  longer  than 
wide;  maxillary  palpi  not  prominent,  the  last  joint  triangular;  thorax  a little 
longer  than  wide,  scarcely  narrowed  in  front,  widest  at  middle,  sides  regularly 
feebly  arcuate,  sinuate  in  front  of  the  hind  angles,  which  are  acute,  slightly 
divergent  and  with  a short  carina;  disc  feebly  convex,  a distinct  incisure  each 
side  of  base;  surface  very  densely  punctured  and  without  strigosity;  elytra  a 
little  wider  than  the  prothorax,  the  sides  nearly  parallel,  narrowed  at  apical 
third,  striate,  strife  punctured,  intervals  flat,  closely  punctate  and  quite  rugous 
at  base;  prosternal  lobe  moderately  prolonged,  its  edge  distinctly  beaded  and 
with  a deeply  impressed  marginal  line  and  another  transverse  line  of  variable 
distinctness  posteriorly,  coarsely  and  closely  punctate  in  front  of  the  transverse 
line,  more  finely  posteriorly;  propleur®  very  opaque,  very  scabrous ; metaster- 
num and  abdomen  closely  finely  punctulate,  but  not  opaque,  finely  cinereo-pu- 
bescent.  Length  7.5 — 8.5  mm. ; .30 — .34  inch. 

This  species  is  more  opaque  and  blacker  than  either  of  the  other 
species,  while  the  punctuation  of  the  thorax  is  dense  and  simple,  not 
strigose.  The  sculpture  of  the  metasternum  shows  but  few  coarser 
punctures  and  these  near  the  middle,  while  the  abdomen  is  entirely 
free  of  them.  The  legs  may  be  entirely  piceous,  or  have  the  tibise 
somewhat  paler.  There  is  absolutely  no  surface  lustre  in  this  species. 
Occurs  in  California  and  western  Nevada. 

C.  planatus  Lee.— Oblong,  nearly  parallel,  depressed,  black,  with  faint 
bronze  tinge  above,  beneath  opaque;  antenufe  black,  a little  longer  than  the 
head  and  thorax,  feebly  serrate,  joints  all  longer  than  wide;  head  coarsely  and 
moderately  closely  punctate;  thorax  distinctly  longer  than  wide,  widest  slightly 
behind  the  middle,  not  narrower  in  front,  sides  feebly  arcuate,  sinuate  in  front 
of  hind  angles,  which  are  slender,  acute  and  slightly  divergent,  distinctly  cari- 
nate ; disc  feebly  convex  (basal  incisures  distinct),  coarsely,  not  densely  punctate.

GEO.  H.  HORN,  M.  D. 


except  near  the  front  angles,  punctures  slightly  strigose;  elytra  scarcely  wider 
than  the  thorax,  parallel  or  slightly  wider  behind  9-  humeri  rounded;  disc 
striate,  strite  punctured,  intervals  flat,  transversely  wrinkled,  irregularly  triseri- 
ately,  subinuricately  punctate ; prosterual  lobe  moderately  prominent,  the  edge 
with  distinct  bead,  a transverse  impressed  line  posteriorly  in  front  of  which  the 
lobe  is  densely  coarsely  punctate,  then  for  a short  distance  sparsely  punctate, 
followed  by  a coarse,  denser  punctuation,  with  finer  punctures  intermixed; 
metasternum  coarsely  punctate,  closely  near  middle,  more  sparsely  laterally,  the 
intervals  finely  closely  punctate;  abdomen  closely,  finely  punctate,  with  scat- 
tered larger  punctures  more  numerous  in  front  and  on  the  apical  segment. 
Length  7.5 — 10  mm. ; .30 — .40  inch. 

In  well  preserved  specimens  the  pubescence  of  the  upper  surface 
is  short  and  inconspicuous;  beneath  very  fine  cinereous  or  fulvous. 
This  is  the  only  species  of  the  group  with  a faint  bronze  surface, 
consequently  less  opaque  than  squalidvs  or  fmiebris.  AVhile  closely 
related  to  the  latter  the  punctuation  of  its  upper  surface  is  less  dense, 
the  antennae  longer,  and  the  punctuation  of  the  under  surface  more 
intermixed  and  coarser. 

The  name  given  to  this  species  was  previously  made  use  of  by 
Eschscholtz,  but  that  being  identical  with  hyperboreus,  and  the  name 
consequently  suppressed,  there  seems  to  me  no  great  objection  to  its 
use  for  the  present  species. 

Occurs  in  western  Pennsylvania,  New  York  and  Canada,  White 
Mountains  (Austin). 

Group  STRIATULUS. 

Prosterual  sutures  arcuate  and  convergent  behind.  Maxillary 
j)alpi  not  prominent,  the  last  joint  elongate  triangular.  Thorax 
densely  punctured  and  opaque,  with,  at  most,  a smooth  median  line, 
base  without  incisures,  carina  of  hind  angles  short.  Elytra  striate, 
equally  at  the  sides.  Legs  slender,  the  tibial  spurs  small.  Form 
depressed.  Body  winged. 

The  only  species  composing  this  group  resembles  a diminutive 
planatm,  but  differs  from  that  group  by  the  form  of  the  prosterual 
sutures.  The  peculiar  sculpture  of  the  thorax  in  the  choris  and 
Melsheimeri  groups  will  prevent  its  being  placed  with  them,  the 
perplexm  series  is  convex,  shining  and  ornate,  while  the  tumescens 
group  is  convex  without  ornamentation. 

C.  striatulus  Lee. — Obloug,  subdepressed,  piceous  black,  opaque,  finely 
cinereo-pubescent;  legs  pale,  the  femora  darker;  antennae  slender,  black,  feebly 
serrate;  head  feebly  convex,  densely  rugosely  punctate;  thorax  a little  wider 
than  long,  narrowed  in  front,  sides  arcuate,  slightly  sinuate  in  front  of  the  hind

lo 

angles,  which  are  stout,  slightly  everted,  and  with  a short  carina ; disc  feebly 
convex,  densely  finely  punctate,  the  median  line  usnally  smooth,  but  not  always  ; 
elytra  as  wide  as  the  thorax,  humeri  obtuse,  sides  nearly  parallel  for  two-thirds 
then  arcuate  to  apex ; disc  rather  fiat,  striate,  equally  from  middle  to  sides,  strife 
punctate,  intervals  feebly  convex,  densely  and  finely  punctulate,  the  surface 
opaque;  prosternum  moderately  closely  punctate,  more  densely  and  finely  at  the 
sides,  the  lobe  short  and  subtruncate,  the  transverse  impression  distinct ; pro- 
pleni’se  closely  finely  punctate,  not  opaque ; metasternum  and  abdomen  densely 
punctate,  a little  more  closely  than  the  propleurse.  Length  3 — 4 mm. ; .12 — .16  inch. 

An  easily  known  species  by  the  group  characters  alone.  In  some 
specimens  the  basal  joints  of  the  antenne  are  somewhat  paler,  but 
these  specimens  have  the  under  side  somewhat  paler  also,  and  are 
probably  less  mature. 

The  distribution  of  this  species  is  rather  remarkable.  Originally 
described  from  the  Lake  Superior  region,  it  extends  westward  to 
Oregon  (Wickham)  and  northern  California,  eastward  to  Ohio 
(Dury)  and  Allegheny,  Pa  (Hamilton). 

Group  CHORIS. 

Prosternal  sutures  arcuate  and  convergent  posteriorly.  Maxillary 
palpi  moderately  prominent,  the  last  joint  elongate  triangular.  Form 
convex.  Elytra  deeply  striate,  more  or  less  ornate.  Thorax  roughly 
granulate,  the  median  line  usually  finely  elevated  and  smooth  ; sur- 
face more  shining. 

The  species  of  this  group  seem  naturally  to  fall  together  by  the 
very  rough  sculpture  of  the  entire  surface  of  the  thorax.  In  the 
dermestoides  group  the  thorax  is  somewhat  granulate  in  front,  but 
comparatively  smooth  posteriorly.  To  this  group  belong  pxdchelhis 
and  sahxdieola,  probably  also  curtus  and  alysidotus  of  the  European 
fauna. 

The  species  known  to  occur  in  our  fauna  may  be  separated  in  the 
following  manner : 

Apical  margin  of  thorax  truncate  at  middle. 

Form  gibbous,  strongly  arched  when  viewed  laterally;  carinse  of  hind  angles 
short ; entirely  pale  above cleliinibis. 

Form  normal,  not  very  convex;  cariufe  of  hind  angles  long;  color  black,  or- 
nate with  yellow. 

Antennae  with  three  basal  joints  pale  yellowish  testaceous;  legs  always 
entirely  pale clioris. 

Antennse  piceous,  very  little,  if  at  all,  paler  at  base;  legs  with  the  femora 
at  least  fuscous  or  piceous. 

Elytra  gradually  attenuate  in  their  posterior  third..  exiguus. 

Elytra  not  attenuate,  ape.x  obtuse oriiatiis. 

Apical  margin  of  thorax  arcuate  at  middle,  slightly  prolonged  over  the  head  and 
somewhat  elevated Cliciillatus.

GEO.  H.  HORN,  M.  D. 


€.  «lellinibi«  n.  sp.— Oblong,  narrowed  posteriorly,  rather  strongly  arched, 
when  viewed  laterally,  convex ; color  above  ochreous,  the  thorax  ferruginous, 
the  head  darker,  elytra  with  vague  fuscous  spaces,  often  absent,  beneath  piceous 
or  brown,  the  last  ventral  segment  and  prosternal  lobe  pale;  antennje  entirely 
pale,  the  outer  joints  scarcely  longer  than  wide;  head  flat,  granular;  thorax 
disti!ictly  longer  than  wide,  sides  slightly  arcuately  narrowed  from  middle  to 
apex,  nearly  straight  posteriorly,  angles  not  divergent,  the  carina  well  marked, 
but  short,  disc  convex,  the  median  line  finely  elevated  and  smooth  ; surface 
closely  granular,  not  forming  strig®  ; elytra  acutely  oval,  narrowed  almost  from 
the  base,  humeri  obliquely  rounded;  disc  deeply  striate,  stri®  rather  wide, 
coarsely  not  closely  punctate,  intervals  convex,  flatter  at  apex ; surface  submu- 
ricately  punctate;  prosternum  closely  and  rather  roughly  punctate,  distinctly 
transversely  impressed  in  front,  the  lobe  moderately  prominent,  but  obtuse  ; pro- 
pleur®  closely  punctate;  metasternum  rather  short,  coarsely  and  closely  punc- 
tate; abdomen  densely  submuricately  punctate,  becoming  granulate  on  the  last 
two  segments;  legs  pale  yellowish  testaceous.  Length  4 — 5 ram. ; .16 — .20  inch. 

This  species  is  remarkable  in  its  sharply  arched  form  when  viewed 
laterally,  as  well  as  by  the  pale  color  of  the  surface.  The  elytra  are 
usually  pale  ochreous,  but  some  specimens  have  a fuscous  space  on 
the  declivity  of  broadly  crescentic  form  extending  forward  by  its 
outer  angle  parallel  with  the  margin.  The  carina  of  the  hind  angles 
is  short,  i.e.,  extending  but  little  in  front  of  the  angles  themselves, 
while  in  all  the  other  species  of  the  group  it  extends  nearly  or  quite 
three-fourths  to  the  ajiex. 

Specimens  were  sent  me  many  years  ago  by  Mr.  F.  G.  Sanborn, 
collected  by  him  in  some  numbers  at  Truro,  Mass.,  a town  on  the 
Cape  Cod  peninsula.  It  should  occur  in  other  places  on  the  Atlantic 
coast. 

C.  choris  Say. — Form  moderately  elongate,  distinctly  narrowed  posteriorly, 
moderately  convex,  black,  opaque,  sparsely  clothed  with  cinereous  or  golden 
hairs,  each  elytron  with  an  angulate  sub-basal  band,  which  extends  to  the 
humeri,  another  transverse  posteriorly  yellow;  anteun®  slender,  feebly  serrate, 
piceotis,  the  three  basal  joints  pale  yellowish  testaceous;  head  feebly  convex, 
coarsely  and  closely  granulate;  thoi-ax  very  little  longer  than  wide,  sides  feebly 
arcuately  narrowed  in  front,  behind  the  middle  nearly  straight,  or  with  a very 
feeble  sinuation  in  front  of  hind  angles,  these  divergent,  the  carina  long,  ex- 
tending fully  three-fourths  to  apex ; disc  convex,  a smooth,  median,  elevated 
line;  surface  rather  coarsely  and  closely  granulate,  elytra  widest  in  front  of 
middle,  thence  gradually  narrowed  to  apex,  humeri  obtuse  ; disc  deeply  striate, 
stri®  punctured,  intervals  convex,  flat  near  apex,  roughly,  not  closely  punctate 
and  somewhat  wrinkled  ; prosternum  closely  punctate,  but  smoother  in  front; 
two  feeble  transverse  grooves  in  front,  lobe  moderately  prominent,  obtuse;  pro- 
pleur®  more  densely  punctate,  but  not  opsique;  nietasternum  and  abdomen 
densely  and  moderately  coarsely  punctate,  but  somewhat  shining;  legs  pale 
rufo-testaceous,  the  femora  rarely  slightly  darker.  Length  3 — 5 mm.;  .12 -.20 
inch.

The  extent  of  yellow  color  in  the  bands  is  variable  so  that  the 
elytra  may  have  more  of  that  color  than  black,  or  vice  versa.  Speci- 
mens of  the  former  were  those  seen  by  Say.  The  normal  style  of 
marking  consists  of  a rather  broad  post-basal  band  with  very  sinuous 
edges,  crossing  the  suture  and  reaching  the  lateral  margin  ending  a 
broad  extension  to  the  humeri,  behind  the  middle  a transverse  band 
crossing  the  suture  where  it  is  broadest,  not  reaching  the  side  margin, 
with  a posterior  extension  along  the  suture.  The  style  of  ornamen- 
tation seems  intermediate  between  that  of  exiguus  and  ornatus.  The 
elytra  at  tip  have  often  a narrow  pale  border. 

Occurs  from  the  Middle  States  region  westward  to  Indiana,  and 
south  to  District  of  Colundiia.  A specimen  collected  by  myself  at 
Fort  Tejon  does  not  appear  to  difler  in  any  respect  from  those  found 
in  the  more  eastern  regions. 

t-.  exiguus  Rand. — Moderately  elongate,  narrowed  posteriorly,  convex, 
black,  opaque  ; elytra  ornate  with  yellow  ; antennae  slender,  piceous,  three  basal 
joints  fuscous,  paler  beneath  : head  flat,  densely  granulate,  sparsely  clothed  with 
short  whitish  pubescence  ; thorax  a little  longer  than  wide  'J, , or  as  wide  as  long 
9;  sides  feebly  arcuately  narrowing  to  the  apex  in  front,  posteriorly  parallel 
with  a slight  siuuation  in  front  of  the  angles,  which  are  acute  and  slightly  di- 
vergent, the  Carina  long,  extending  fully  three-fourths  to  apex;  disc  convex, 
closely  granulate,  the  median  line  smooth  and  distinctly  elevated ; surface 
sparsely  pubescent,  more  conspicuously  at  the  hind  angles;  elytra  widest  a little 
behind  the  humeri,  then  gradually  narrowed  to  apex,  humeri  obtuse;  disc  rather 
deeply  striate,  but  less  so  near  the  apex,  striaj  punctate,  intervals  slightly  convex 
at  base  only,  rather  closely  submuricately  punctate,  but  smoother  at  apex, 
sparsely  cinereo-pubescent;  prosteruum  moderately  closely  punctate,  but  smoother 
in  front  between  the  two  transverse  grooves,  the  lobe  modeiate,  but  obtuse;  pro- 
pleurfe  subopaque,  densely  punctate ; metasternum  densely  and  rather  coarsely 
punctate;  abdomen  less  closely  and  less  coarsely  punctate,  last  segment  rufes- 
cent;  femora  and  tai-si  piceous,  the  tibiae  pale.  Length  2.5 — 3 mm.;  .10 — .12 
inch. 

This  species  has  been  the  cause  of  some  confusion,  in  which  every 
author  who  has  treated  of  our  Elateridte  has  had  part.  Described 
originally  by  Randall,  in  1838,  under  the  above  name  it  received  a 
second  (guttatulus)  from  Mesheimer  in  1845. 

In  1853,  Dr.  LeConte,  in  his  “ Revision  of  the  Elateridie,”  placed 
exiguus  and  guttatulus,  in  part,  in  synonymy  with  imlchellus.  When 
the  Melsheimer  collection  became  accessible  to  him  it  was  observed 
that  two  species  had  been  confounded,  each  represented  by  a single 
poor  specimen,  one  representing  the  present  species,  the  other  it  was 
thought  might  prove  to  be  quadripustulatus  of  Europe  accidentally 
introduced  in  the  cabinet.  This  latter  specimen  bore  the  typical

label,  ami  was  therefore  assumed  to  be  the  type,  notwithstanding  the 
fact  that  the  very  good  description  given  by  Melsheiiner  points  clearly 
to  exigmis.  It  is,  therefore,  without  hesitation  that  I suppress  gut- 
iatnlus,  absolutely,  as  a synonym,  and  for  the  species  erroneously  so 
determined  by  LeConte  the  name  Melsheimeri  is  proposed,  and  will 
be  found  in  its  proper  group. 

Ur.  Candeze  simply  followed  in  the  lead  of  LeConte.  A few 
months  ago  (“  Entomological  News,”  1890,  p.  9)  I continued  the 
same  error  through  not  having  imldiellm  for  comparison.  The  sahu- 
licola  which  had  been  sent  me  instead,  serving  alone  for  comparison, 
led  me  to  believe  that  our  specimens  fully  met  the  requirements  noted 
by  Fauvel  (”  Revue  Ent.”  1889,  p.  142). 

On  comparison  of  exiguus  with  puleheUus,  it  will  be  observed  that 
the  former  is  more  slender  and  convex,  the  elytral  stride  more  dis- 
tinct at  apex  and  the  elytra  at  tip  piceous  without  the  bifid  space 
seen  in  the  other.  The  three  basal  joints  of  the  antennae  are  pale 
rufo-testaceous  in  pulchellus,  piceous  in  exiguus,  although  paler  be- 
neath. The  femora  are  also  paler  in  the  former  species. 

There  seems  to  be  a closer  resemblance  between  pulchellus  and 
ehoris.  They  have  similarly  colored  antennte  and  legs,  but  the  elytra 
are  more  roughly  sculptured,  the  strite  deeper  at  apex,  and  the  bifid 
spot  absent  in  ehoris. 

Occurs  in  the  New  England  and  Middle  States;  Massachusetts 
(Blanchard)  to  District  of  Columbia  (Ulke). 

C.  oriiatiis  Lee. — Oblong,  moderately  convex,  not  attenuate  posteriorly, 
black,  opaque;  surface  finely  ciuereo-pubescent ; elytra  either  ornate,  as  in  pul- 
chellus, or  with  merely  two  small  spots  posteriorly  or  entirely  black ; antenuse 
slender,  feebly  serrate,  entirely  piceous ; front  flat,  densely  granulately  punctate  ; 
thorax  a little  variable  in  form,  as  wide  as  long  ?,  or  a little  longer  than  wide 
"J, , narrowed  in  front,  widest  usually  at  or  near  the  base,  sides  feebly  arcuate  in 
front,  behind  the  middle  nearly  straight  and  parallel,  or  with  a faint  sinuation 
in  some  males,  the  angles  not  divergent,  the  carina  extending  nearly  three- 
fourths  to  apex,  disc  convex,  the  median  line  finely  elevated  and  smooth  ; surface 
opaque  granulate,  the  granules  elongate  and  forming  short  strigae  posteriorly; 
elytra  parallel,  arcuately  narrowed  at  apical  third,  humeri  obtuse ; disc  moder- 
ately deeply  striate,  striae  punctured,  intervals  flat,  slightly  convex, at  base  in 
male,  roughly  punctate,  more  or  less  transversely  wrinkled  and  rugulose,  espe- 
cially near  the  base;  prosternura  rather  coarsely  and  closely  punctate,  especially 
in  front,  two  transverse  impressions  anteriorly,  the  lobe  moderately  prominent, 
but  obtuse;  propleurae  closely  punctate,  but  not  opaque;  metasternum  densely 
and  rather  roughly  punctate ; abdomen  densely  punctate,  less  coarsely  than  the 
metasteruum.  Length  3—5  mm. ; .12— .20  inch.

The  males  are  more  slender  and  rather  more  coarser  than  the 
females,  the  thorax  a little  longer  than  wide  and  with  a faint  sinua- 
tion  in  front  of  the  hind  angles,  which  are,  however,  not  divergent. 

There  is  considerable  variation  in  color  in  the  specimens  before 
me,  and  three  varieties  may  he  indicated. 

Var.  ornatus  Lee. — The  elytra  have  two  yellow  spaces.  The  an- 
terior is  transverse,  post-basal,  of  irregular  form,  widest  externally, 
but  not  extending  to  the  humerus  nor  margin.  The  posterior  is 
behind  the  middle,  transversely  oval,  not  reaching  the  side  nor  the 
suture.  The  femora  are  piceous,  the  tibise  and  tarsi  usually  paler. 

Var.  colon  Horn. — Here  the  elytral  markings  are  reduced  to  a 
small  round  spot  on  each  side  in  the  position  of  the  posterior  spot 
of  the  jireceding  variety.  The  legs  may  be  as  in  ornatus,  or  entirely 
piceous. 

Var.  rncerens. — Entirely  black,  without  elytral  markings.  The 
legs  are  nearly  always  piceous. 

Occurs  in  California  from  San  Diego  northward  in  the  central 
valley,  as  well  as  along  the  coast  region  to  Oregon  (Blanchard). 

C.  ciicullatns  n.  sp. — Elongate  oval,  rather  broader  in  proportion  to  its 
length  than  usual  in  the  genus,  moderately  convex,  black;  elytra  with  faint 
bronze  lustre;  thorax  cinereo-puhescent  near  the  hind  angles;  elytra  with  ex- 
tremely fine  and  short  flavo-cinereous  pubescence ; antennae  slender,  feebly  ser- 
rate, entirely  piceous;  head  flat,  closely  punctate;  thorax  scarcely  longer  than 
wide,  sides  straight  posteriorly,  gradually  arcuately  narrowed  from  middle  to 
apex,  hind  angles  not  divergent,  the  cariua  extending  in  front  of  middle,  apical 
margin  arcuate  and  prolonged  over  the  head,  deejtly  sinuate  near  the  front  an- 
gles; disc  convex,  without  smooth  median  line;  surface  very  coarsely  granulate 
but  somewhat  smoother  on  the  declivity  and  near  the  hind  angles  ; elytra  with 
sides  parallel,  arcuately  narrowed  at  apical  third;  apex  obtuse,  humeri  obtuse; 
disc  moderately  convex,  striate,  strife  punctate,  intervals  slightly  convex  in  their 
entire  extent  and  closely  punctulate ; prosternum  granulate  in  front,  rather 
finely  punctate  posteriorly,  a faint  transverse  impression  in  front,  the  lobe  short 
and  obtuse;  propleurfe  more  finely  and  closely  punctate  than  the  sternum  ; met- 
asternuin  a little  more  coarsely  punctate;  abdomen  rather  more  finely  and 
densely ; legs  piceous,  the  tibife  and  tarsi  paler.  Length  3.5  mm. ; .14  inch. 

This  species  is  easily  known  by  the  form  of  the  apical  border  of 
the  thorax  of  which  the  middle  forms  a short  lobe  partly  concealing 
the  head  from  above.  On  each  side  of  this  lobe  is  a rather  deep 
sinuation  causing  the  front  angles  to  be  more  acute  and  prominent 
than  usual. 

Specimens  have  been  examined  from  the  Indian  Territory ; Co- 
lumbus, Texas  (Schwarz),  Utah  (Ulke).  A specimen  has  been  seen 
labeled  Ohio,  but  the  locality  seems  doubtful.

Group  MELSHEIMERI. 

Prosternal  sutures  arcuate  and  couvergeut  posteriorly.  Maxillary 
palpi  not  promiiieiit,  the  last  joint  elongate  triangular,  the  apex 
rounded.  Thorax  asperate,  or  subgranulate  in  front,  becoming 
gradually  quite  smooth  posteriorly,  the  base  without  incisures.  Ely- 
tra striate ; tibiae  slender,  spurs  small ; surface  usually  shining,  elytra 
often  ornate.  Body  winged. 

A group  of  small  species  standing  naturally  betw^een  the  choris  and 
perplexus  series.  Its  essential  character  is  in  the  sculpture  of  the 
thorax,  the  anterior  portion  being  quite  roughly  or  more  densely 
sculptured,  and  the  basal  portion  quite  smooth.  Some  curious  sexual 
peculiarities  have  been  observed  in  some  of  them,  of  rare  occurrence 
in  Elateridae,  but  by  no  means  rare  in  Eucnemidae,  consisting  of  tu- 
bercles or  pubescent  spots  on  the  first  two  ventral  segments. 

The  elements  composing  the  group  are  by  no  means  homogeneous, 
and  might  be  again  divided  as  the  last  three  species  have  not  that 
very  marked  difference  in  sculpture  of  the  thorax  so  well  shown  in 
the  others.  As  a whole,  the  group  is  known  from  the  striatulus  series 
by  its  more  convex  form  and  the  evident  inequality  of  the  thoracic 
punctuation  ; from  the  choris  series  by  the  opaque,  granular  thorax 
of  these ; the  j)erplexus  series  has  usually  a sparsely  punctate  thorax, 
and  in  any  event  the  punctures  are  equal  and  equally  disposed. 

The  following  species  are  known  to  occur  in  our  fauna : 

Prosternal  sutures  widely  double,  smooth  and  grooved  in  nearly  their  entire 
length  ; thorax  simply  emarginate  at  apex  when  seen  from  above. 

Antennae  and  legs  pale;  anterior  tibiae  of  male  not  broader  than  in  female, 
the  first  ventral  'J,  with  a flattened  space  at  middle  enclosing  a 
tubercle Melsliei  meri. 

Antennae  piceous,  tip  of  first  and  the  second  and  third  joints  paler;  legs  j)ale, 
femora  darker ; anterior  tibiae  of  male  nearly  twice  as  broad  as  in 
the  female,  the  first  ventral  'J,  scarcely  flattened,  but  with  an  oval 
hairy  spot quad  rig  uttatus. 

Antennae  piceous,  paler  at  base;  legs  pale,  femora  piceous;  anterior  tibiae  of 
male  not  broader,  the  first  and  second  ventrals  of  male  with  a tu- 
bercle near  the  posterior  border vatiriiius. 

Antennae  as  in  qiiadriguttatus,  legs  similar;  anterior  tibiae  of  male  broader 
than  in  female,  but  less  marked;  first  ventral  of  male  gibbous  be- 
tween the  coxae,  rather  suddenly  declivous  posteriorly  and  fringed 

with  longer  hair dermestoides. 

Prosternal  sutures  very  narrowly  double,  not  grooved. 

Carina  of  the  hind  angles  of  thorax  extending  to  or  beyond  the  middle  of  the 
thorax.

Form  subdepressed;  thorax  distinctly  rugulose  iu  front;  posterior  coxal 
plates  obliterated  externally. 

Thorax  simply  emarginate  in  front;  no  ventral  sexual  characters  in  either 
sex dispersiis. 

Thorax  sinuate  each  side  at  apex,  the  middle  somewhat  elevated  and  pro- 
longed over  the  head  ; second  ventral  of  9 with  oval  pubescent 
spot gra<lariiis. 

Form  convex;  thorax  simply  a little  more  coarsely  punctate  in  front;  pos- 
terior coxal  plates  not  obliterated  externally ; sides  of  thorax  sinuate 

in  front  of  hind  angles tuniesceiis* 

Carina  of  hind  angles  of  thorax  very  short,  not  extending  beyond  the  angles. 

Piceous,  faintly  bronzed  ; sides  of  thorax  sinuate  in  front  of  hind  angles, 
these  distinctly  divergent iniisciilus. 

Brownish  opaque;  sides  of  thorax  straight  posteriorly,  the  hind  angles  not 
divergent diibitis. 

It  will  be  observed  that  two  European  species  are  introduced  in 

the  table,  the  names  in  italics.  These  have  been  the  cause  of  much 

of  the  trouble  experienced  in  identifying  our  species.  On  several 
occasions  specimens  have  come  to  me  labeled  dermestoides  with  quad- 
riguttaim  as  a variety-  Whether  that  is  the  view  generally  held  in 
Europe  is  hardly  my  province  to  investigate,  but  there  is  no  question 
in  my  mind  that  they  are  two  well  defined  species  easily  separated 
by  the  sexual  characters  of  the  male.  I find  no  mention  made  of 
the  latter  in  any  literature  examined,  they  have  even  escaped  the 
acute  observation  of  C.  G.  Thomson. 


C.  Melsheiiiieri  n.  sp.— Oblong,  moderately  convex,  piceous  black  shining, 
sparsely  finely  pubescent,  each  elytron  with  a humeral  and  subapical  yellow  spot; 
antennae  slender,  feebly  serrate,  joints  all  longer  than  wide,  ferruginous,  joints 
2-3  paler,  basal  joint  darker;  head  slightly  convex,  punctate,  somewhat  asper- 
ate; thorax  wider  than  long,  narrowed  in  front,  sides  arcuate,  straight  for  a 
short  distance  near  base,  hind  angles  broad,  but  acute,  at  tip,  the  carina  extend- 
ing finely  three-fourths  to  apex ; disc  convex,  shining,  asperately  punctate  in 
front,  gradually  evanescent  behind  and  quite  smooth  near  the  base,  median  line 
distinctly  smoother  in  front;  elytra  as  wide  at  base  as  the  thorax,  humeri  ob- 
tuse, sides  nearly  parallel,  arcuately  narrowed  at  apical  third,  apices  obtuse,  disc 
striate,  strise  extremely  finely  punctate,  intervals  slightly  convex,  sparsely  mi- 
nutely punctulate,  the  humeral  spot  small,  rhomboidal,  the  subapical  round  • 
prosternum  sparsely  punctate,  more  coarsely  and  closely  in  front,  the  lobe  mod- 
erately prominent,  rather  obtuse,  prosternal  sutures  widely  double,  smooth, 
grooved  nearly  their  entire  length,  propleurje  feebly  shining,  punctures  fine  and 
close;  metasternum  moderately  closely  punctate,  the  last  segment  more  densely 

and  opaque;  legs  pale  rufo-testaceous.  the  femora  slightly  darker.  Leno^th  2 

2.25  mm. ; .08 — .09  inch. 

The  first  ventral  segment  of  the  male  has  a flattened  space  at 
middle,  in  the  centre  of  which  is  a slightly  elevated  broad  tubercle.

GEO.  H.  HORN,  M.  D. 


The  female  has  simjile  ventral  segments,  the  antenme  a little  shorter, 
and  the  joints,  consequently,  relatively  broader. 

Superficially  this  species  closely  resembles  quadriguitatus  (tetra- 
graphus),  but  the  thorax  is  smoother,  i.  e.,  the  roughness  does  not 
extend  so  far  j)osteriorly,  and  the  median  smooth  line  is  shorter. 

Thomsom  states  (Skand.  Col.  vi,  }).  116)  that  in  the  male  of  tetra- 
graphus  the  anterior  tibije  are  inwardly  dilated  near  the  apex.  No 
such  structure  is  seen  in  our  species. 

This  species  is  the  form  for  which  Dr.  LeConte  retained  the  Mel- 
sheimer  name  guttatnius,  but  I have  elsewhere  shown  that  the  de- 
scription applies  accurately  to  that  described  previously  as  exigtms 
Rand. 

Occurs  in  the  District  of  Columbia  (Ulke) ; northern  Illinois. 

C.  caiiriiiiis  n.  sp. — Oblong,  moderately  convex,  piceous,  slightly  shining, 
surface  finely  ciuereo-puhescent,  each  elytron  with  a small  yellow  spot  at  hu- 
merus, a second  suhapical,  both  indistinct;  antennae  slender,  feebly  serrate,  en- 
tirely piceous;  head  convex,  a slight  median  impression  posteriorly,  surface 
opaque,  finely  asperate;  thorax  a little  broader  than  long,  narrowed  in  front, 
apex  emarginate,  sides  parallel  posteriorly,  then  gradually  arcuately  narrowed 
to  the  front,  hind  angles  stout  but  acute,  the  carina  extended  two-thirds  to  apex, 
disc  convex,  median  line  somewhat  smooth  in  front,  surface  asperately  punctate 
in  front,  finely  and  closely  posteriorly ; elytra  as  wide  as  the  thorax,  humeri 
obtuse,  sides  scarcely  arcuate,  apical  third  arcuately  narrowed,  apex  obtuse,  disc 
striate,  striae  faintly  punctured  at  the  sides,  intervals  feebly  convex,  minutely 
and  moderately  closely  punctate ; prosternum  finely  not  closely  punctulate ; 
a distinct  transverse  impression,  anterior  to  which  the  punctuation  is  rather 
coarse  and  rugose;  lobe  prominent,  obtusely  rounded  in  front,  sutures  widely 
double,  smooth  and  grooved,  propleurae  opaque,  densely  and  very  minutely  punc- 
tulate; metasternum  and  abdomen  densely  finely  punctulate;  femora  piceous, 
tibiae  and  tarsi  testaceous.  Length  2 — 2.5  mm. ; .08 — .09  inch. 

The  males  have  an  oval  flattened  space  in  the  middle  of  the  first 
v^entral  segment  enclosing  a small  tubercle,  a second  tubercle  near 
the  margin  of  the  second  segment.  Females  are  not  known  to  me. 

In  a superficial  comparison  this  species  might  be  supposed  to  be 
merely  a Melsheimeri  with  sj)ots  less  distinctly  marked,  but  here  the 
antennte  are  quite  black  and  the  male  sexual  characters  different. 

Occurs  in  the  State  of  Washington. 

CL  «lis|>ersiis  n.  sp. — Oblong,  moderately  convex,  piceous  black,  feebly

and  subapical  yellow  spot,  or  without  any  ; autenuse  slender,  feebly  serrate,  en- 
tirely piceous,  or  with  joints  2-3  pale;  head  convex,  sparsely  asperately  punc- 
tate; thorax  a little  wider  than  long,  apex  emarginate,  sides  parallel  for  a short 
distance  posteriorly,  thence  arcuately  narrowed  to  the  front,  the  hind  angles

broad,  but  acute;  tbe  carina  extending  two-thirds  to  apex,  disc  convex,  median 
line  smooth  in  front,  surface  asperately  punctate  in  front,  sparsely  punctate  pos- 
teriorly; elytra  as  wide  at  base  as  the  thorax,  but  evidently  narrowed  from  the 
obtuse  humeri,  disc  striate,  striae  finely  puuctate,  intervals  slightly  convex,  finely 
moderately  closely  punctulate;  prosternum  not  closely  punctate,  a feeble  trans- 
verse impression  in  front,  lobe  obtusely  prominent,  coarsely  and  closely  punc- 
tate, the  sutures  very  narrowly  double,  but  not  at  all  excavate,  propleune  less 
shining,  very  minutely  and  densely  punctulate;  metasternum  and  abdomen 
densely  and  finely  punctulate ; legs  testaceous,  the  femora  darker.  Length  2.25 
mm. ; .09  inch. 

The  two  specimens  before  me,  which  seem  to  be  male  and  female, 
exhibit  no  ventral  sexual  characters.  One  % from  Washington  has 
entirely  piceous  antenme,  a very  faint  humeral  spot,  the  subapical 
more  distinct ; that  from  Nevada  has  no  elytral  spots,  and  the  second 
and  third  joints  of  the  antennse  pale.  A third  from  Nova  Scotia, 
probably  representing  a distinct  species,  has  the  elytral  spots  well 
marked  as  in  Mehheimeri,  and  the  three  basal  joints  of  the  antennse 
pale.  In  the  absence  of  a male  it  is  for  the  present  placed  with  this 
species. 

Occurs  in  Nevada,  Washington  (and  Nova  Scotia?). 

C.  gradariiis  n.  sp. — Obloug,  feebly  convex,  piceous-black,  subopaque, 
faintly  bronzed,  surface  finely  cinereo-pubescent,  more  evidently  in  the  depression 
near  the  hind  angles;  antenme  black,  slender,  feebly  serrate;  front  slightly  im- 
pressed, rather  coarsely  and  roughly  punctured  ; thorax  very  little  wider  than 
long,  narrowed  in  front,  sides  posteriorly  straight,  in  front  gradually  arcuate  to 
apex,  apical  border  sinuate,  slightly  elevated  at  middle  and  prolonged  over  the 
head,  hind  angles  broad,  but  acute,  the  carina  extending  two-thirds  to  apex,  disc 
convex,  asperately  puuctate  in  front,  more  finely  and  smoother  posteriorly;  ely- 
tra as  wide  at  base  as  tbe  thorax,  humeri  obtuse,  sides  feebly  arcuate,  apex  ob- 
tusely rounded,  disc  striate,  strife  punctulate,  intervals  feebly  convex,  punctulate  ; 
prosternum  sparsely  punctate,  shining,  a feehle  transverse  impression  in  front, 
lobe  not  prominent,  obtusely  rounded,  coarsely  puuctate.  prosternal  sutures 
simple,  without  trace  of  excavation,  propleurfe  subopaque,  densely  finely  punc- 
tulate; metasternum  and  abdomen  closely  finely  puuctate;  legs  rufo-testaceous, 
femora  darker.  Length  2 mm. ; .08  inch. 

The  male  shows  iio  sexual  characters  on  the  ventral  segments,  the 
female,  however,  has  a finely  pubescent,  oval  spot  at  the  middle  of 
the  second  segment. 

This  species  is  the  one  I had  thought  identical  with  dermestoides, 
but  a closer  examination  shows  it  to  be  our  equivalent,  on  this  con- 
tinent, of  curtvs  of  Eurojie.  The  sinuation  of  the  apical  border  of 
the  thorax,  although  sufficiently  well  marked  in  comparison  with  the 
others  of  the  group,  is  less  distinct  than  in  cncidlatus.  The  denser 
silken  pubescence  of  the  hind  angles  of  the  thorax  is  rather  a con-

spicuous  feature  of  tliis  species.  The  two  specimens  before  me  are 
precisely  alike  above  and  show  no  traces  of  pale  spots. 

Collected  by  IMr.  D.  W.  Coquillett  at  Los  Angeles. 

tiiiuesceiis  Lee. — Oblong,  convex,  facies  robust,  piceous-black,  with 
slight  feneous  surface  lustre,  sparsely  cinereo-pubescent ; antennae  either  entirely 
piceons,  or  with  joints  2-3  paler;  joints  subtriangular  from  4-10;  head  convex, 
closely  punctate  ; thorax  as  wide  as  long,  narrowed  in  front,  sides  rather  strongly 
arcuate,  sinuate  in  front  of  the  hind  angles,  which  are  acute,  slightly  divergent, 
with  the  Carina  extending  nearly  half  to  apex,  disc  convex,  the  median  line 
smooth,  surface  moderately  closely  punctate,  a little  roughened  near  the  apex 
only,  gradually  more  finely  posteriorly;  elytra  oval,  widest  a little  behind  the 
middle,  humeri  obtuse,  disc  convex,  striate,  strife  punctate,  intervals  slightly 
convex  near  the  base,  sparsely  punctate,  more  coarsely  in  front,  the  lobe  obtuse, 
propleurfe  more  closely  punctate;  metasteruum  more  coarsely  punctate;  abdo- 
men more  finely  and  closely  punctate  ; legs  rufo-testaceous,  the  femora  piceons. 
Length  3 — 4 mm. ; .12 — .16  inch. 

The  prosteriial  sutures,  while  doubled  as  usual  in  the  group,  are 
very  narrow,  although  in  the  female  they  are  distinctly  wider  than 
in  the  male. 

The  form  of  this  species  is  quite  that  of  a diminutive  Cardiopho- 
rus.  The  sculpture  of  the  thorax  does  not  have  that  marked  rough- 
ness seen  in  the  preceding  species.  The  posterior  coxal  plates  are 
not  obliterated  externally. 

Occurs  on  the  north  shore  of  Lake  Superior  (LeConte),  upper 
Canada  (Pettit)  and  New  Mexico  (Fuller);  White  Mountains 
(Blanchard). 

C.  musculus  Esch. — Oblong,  convex,  fscies  robust,  black,  shining,  surface 
distinctly  seneous,  sparsely  pubescent;  anteniife  piceous,  slightly  serrate ; head 
convex,  closely,  subasperately  punctate;  thorax  broader  than  long,  very  little 
narrowed  in  front,  sides  strongly  arcuate,  sinuate  near  the  hind  angles,  which 
are  acute,  slightly  divergent,  and  with  a very  short  carina,  disc  convex,  median 
line  smooth,  surface  closely  and  slightly  asperate  in  front,  gradually  more  finely 
and  s])arsely  behind  ; elytra  oval,  widest  at  middle,  humeri  rounded,  disc  convex, 
striate,  less  deeply  at  sides,  strife  punctate,  intervals  slightly  convex  near  the 
base,  moderately  closely,  but  finely  submuricately  punctate,  forming  transverse 
ridges  near  the  base;  prosternum  sparsely  punctate,  a distinct  transverse  groove 
in  front,  the  lohe  rather  obtuse,  propleurae  similarly  punctate;  metasteruum  a 
little  more  coarsely  punctate  ; abdomen  punctate  similarly  to  the  propleuraj,  but 
more  densely;  legs  piceous,  the  tibife  and  tarsi  paler.  Length  2.5 — 3 mm.;  .10 — 
.12  inch. 

The  prosteriial  sutures  are  not  at  all  doubled  in  this  species.  The 
carina  of  the  hind  angles  of  the  thorax  is  here  very  short  and  in- 
conspicuous, and  might  readily  be  passed  unobserved.  The  posterior

coxal  plates  are  obliterated  externally,  the  posterior  edge  being  con- 
fluent with  the  anterior. 

Occurs  in  Alaska. 

C.  tliibius  Horn. — Oblong,  moderately  convex,  fuscous,  feebly  shining, 
sparsely  pubescent,  hind  angles  of  thorax  paler;  antennae  slender,  scarcely  ser- 
rate, fuscous,  the  three  basal  joints  paler;  head  slightly  flat,  closely  subasper- 
ately  punctate;  thorax  a little  wider  than  long,  narrowed  in  front,  sides  parallel 
behind,  arcuate  anteriorly,  the  hind  angles  nearly  rectangular,  the  cariua  mod- 
erate in  length,  disc  convex,  the  median  line  smoother,  surface  closely  punctate 
and  somewhat  scabrous  in  front,  gradually  more  smooth  posteriorly  ; elytra  ob- 
long, sides  parallel,  arcuate  at  apical  third,  humeri  obtuse,  disc  striate,  a little 
less  at  the  sides,  strije  relatively  coarsely  punctate,  intervals  flat,  finely  and 
moderately  closely  punctate;  prosternum  sparsely  punctate,  transversely  im- 
pressed in  front,  the  lobe  short  and  obtuse,  propleurfe  finely  and  indistinctly 
punctate;  metasternum  more  coarsely  punctate;  abdomen  very  finely  and  mod- 
erately closely  punctate  ; legs  pale.  Length  2 — 2.5  mm.;  .08 — .10  inch. 

The  under  side  of  body  is  notably  paler  than  the  upper,  especially 
on  the  sternal  members  and  the  epipleurte.  The  posterior  coxal 
plates  are  obliterated  externally. 

This  species  has  the  same  general  outline  of  body  as  in  the  Mel- 
sheimeri  series,  but  is  more  convex. 

Occurs  in  Nebraska  and  Dakota  (Ulke). 

Group  PERPLEXUS. 

Prosternal  sutures  arcuate  and  rather  strongly  convergent  poste- 
riorly. Maxillary  palpi  moderately  prominent,  the  last  joint  elon- 
gate triangular.  Elytra  moderately  deeply  striate,  ornate  with  yel- 
lowish spaces.  Form  rather  slender,  convex.  Thorax  simply 
punctate,  not  rugose,  the  median  line  not  elevated  nor  smooth,  with- 
out basal  incisures.  Legs  slender,  tibial  spurs  very  small. 

Among  the  species  with  arcuate  prosternal  sutures,  those  of  this 
group  are  known  by  the  striate  and  ornate  elytra,  with  comparatively 
smooth  thorax.  The  only  exotic  species  known  to  me  as  belonging 
here  is  quadrijnistulatus  Fab. 

The  species  are  separated  as  follows : 

Thorax  distiuctly  narrowed  iu  front,  at  base  as  wide,  or  wider  than  at  middle. 

Antennfe  and  legs  entirely  piceous geiitilis. 

Thorax  coarctate  at  base  and  apex  nearly  equally,  widest  at  middle,  hind  angles 
slender,  slightly  divergent.  Legs  and  three  basal  joints  of  the  an- 
tennse  yellowish  testaceous. 

Elytral  humeri  obtuse,  body  with  well  developed  wings,  striae  scarcely  more 
punctate  than  the  intervals ; each  elytron  with  two  yellow  spaces, 
humeral  and  subapical sestivus. 

Elytral  humeri  rounded,  body  very  feebly  winged,  striae  more  coarsely  punc- 
tate than  the  intervals. 

Each  elytron  with  two  yellow  spots;  thorax  wider  than  long. 

quadripustulatus. 

Each  elytron  with  a humeral  spot  only ; thorax  distinctly  longer  than 
wide perplexus.

Tlie  European  species  is  introduced  in  the  table  for  the  comparison 
of  its  characters  with  the  two  in  our  fauna  most  closely  allied  to  it. 

C’.  soiililis  Lee.— Moderately  convex,  piceous,  feebly  shining,  clothed  with 
tine  flavo-cinereous  silken  pubescence,  each  elytron  with  an  arcuate  humeral 
oblique  yellow  stripe  and  a short  transverse  one  behind  the  middle;  antennse 
slender,  ])iceous,  feebly  serrate,  joints  all  longer  than  wide;  head  vaguely  longi- 
tudinally impressed,  finely  and  moderately  punctate,  slightly  scabrous;  thorax 
as  broad  as  long,  narrowed  in  front,  sides  anteriorly  feebly  arcuate,  nearly 
straight  at  basal  fourth,  the  hind  angles  stout  not  divergent,  tipped  with  yellow, 
the  Carina  extending  nearly  to  middle,  but  very  feeble  in  front,  disc  moderately 
closely  finely  punctate,  the  median  smooth  line  very  feeble,  the  pubescence  ir- 
regularly arranged,  giving  a holosericeous  appearance;  elytra  as  wide  at  base  as 
the  thorax,  humeri  obtusely  rounded,  disc  feebly  arcuate,  gradually  narrowed 
from  base,  disc  deeply  striate,  striae  closely  punctate,  intervals  convex,  densely 
punctulate,  somewhat  scabrous  near  the  base;  prosternum  sparsely  punctate,  a 
little  more  coarsely  in  front,  with  two  vague  transverse  impressions,  the  lobe 
obtusely  rounded  with  narrowly  beaded  margin,  propleurm  a little  more  closely 
punctate  than  the  sternum,  shining ; metasternum  and  abdomen  a little  more 
coarsely  punctate  than  the  prosternum,  the  apical  segment  somewhat  roughened. 
Length  3-4  mm.;  .12— .16  inch. 

In  the  male  the  form  is  more  slender,  and,  contrary  to  what  has 
been  noticed  elsewhere  in  Elateridte,  the  elytral  intervals  are  less 
convex.  The  hind  angles  are  also  very  slightly  divergent.  The 
frontal  impression  may  be  vaguely  triangular. 

The  yellow  humeral  lunule  of  the  elytra  is,  in  form,  vei*y  like  the 
same  mark  in  Cicindela.  The  legs  are  jticeous,  but  sometimes  the 
tibite  and  tarsi  are  paler. 

Frotn  either  of  the  species  of  this  group  this  differs  in  having  the 
thorax  broadest  at  base,  the  antenme  and  legs  piceous. 

Occurs  in  Nebraska  (Ulke),  Wyoming  and  Washington  (Morrison) 

C.  sestivns  Horn.— Oblong,  moderately  elongate  and  convex,  piceous,  basal 
joints  of  antennse,  hind  angles  of  thorax,  legs,  a humeral  and  subapical  spot  on 
each  elytron  yellowish  testaceous,  surface  moderately  shining,  sparsely  pubes- 
cent; antennte  feebly  serrate,  joints  slender;  front  rather  flat,  head  vaguely 
punctate  and  slightly  rugulose ; thorax  not  longer  than  wide,  slightly  narrowed 
in  front,  widest  slightly  in  front  of  middle,  sides  arcuate,  distinctly  sinuate  in 
front  of  the  hind  angles,  which  are  slender,  acute  and  distinctly  divergent,  the 
Carina  not  prolonged,  disc  moderately  convex,  not  closely  punctate,  the  median 
smooth  line  feebly  evident  posteriorly;  elytra  as  wide  at  base  as  the  thorax, 
humeri  obtuse,  sides  feebly  arcuate,  disc  striate,  strife  punctate,  intervals  slightly 
convex,  not  closely  punctulate;  prosternum  sparsely  finely  punctate,  vaguely 
transversely  impressed,  the  lobe  short  and  truncate,  propleur®  more  coarsely  and 
punctate  than  the  prosternum  at  middle,  shining;  mesosternum  punctured  simi- 
larly to  the  propleui-fe,  the  abdomen  a little  more  finely.  Length  4 — 5 mm. ; 
.16 — .20  inch.

In  this  species  tlie  elytra  are  colored  very  like  gentilu.  The  more 
striking  differences  between  it  and  the  others  of  the  group  are  suffi- 
ciently detailed  in  the  table. 

Occurs  in  Missouri ; collected  by  Dr.  S.  V.  Summers,  Ohio  (Blan- 
chard). 

C.  perplexiis  Horn. — Moderately  elongate  and  convex,  piceous-black, 
shining,  sparsely  pubescent,  three  basal  joints  of  the  antennse,  legs  and  a humeral 
spot  reddish  yellow;  antennse  slender,  feebly  serrate;  front  rather  flat,  sparsely 
punctate;  thorax  distinctly  longer  than  wide,  nearly  equally  narrowed  at  base 
and  apex,  widest  a little  in  front  of  middle,  sides  arcuate,  distinctly  sinuate  in 
front  of  the  hind  angles,  which  are  small,  acute  and  distinctly  divergent,  the 
Carina  distinct,  disc  convex,  sparsely  but  equally  punctate,  median  smooth  line 
distinct;  elytra  elongate  oval,  widest  at  middle,  humeri  rounded,  the  disc  striate, 
strise  rather  deep  and  coarsely  punctate,  the  intervals  convex,  shining  and  very 
sparsely  punctulate ; prosternum  transversely  impressed  in  front,  the  lobe  short 
and  obtuse,  surface  sparsely  finely  punctate  at  middle,  more  distinctly  at  the 
sides,  propleura*,  shining,  a little  more  coarsely  and  less  closely  punctate  than  the 
sternum;  metasternum  a little  more  coarsely  and  closely  punctate;  abdomen 
more  finely  than  this.  Length  2.75 — 3.5  mm. ; .11 — .14  inch. 

This  species  resembles  that  variety  of  quadripmtvlatus  in  which 
the  humeral  spot  alone  is  present,  but  it  differs  in  having  the  thorax 
very  obviously  longer  than  wide,  the  elytral  striie  more  coarsely 
punctate,  and  the  intervals  smoother.  The  hind  angles  of  the  thorax 
are  sometimes  tipped  with  yellow,  but  this  is  by  no  means  frequent. 
The  body  is  very  feebly  winged. 

Occurs  in  the  District  of  Columbia,  where  it  has  been  collected 
abundantly,  at  times,  by  Mr.  Ulke. 

Group  PECTORALIS. 

Prosternal  sutures  arcuate,  convergent  posteriorly,  nearly  twice  as 
widely  separated  at  the  apical  angles  as  at  the  coxae.  Maxillary 
palpi  not  prominent,  the  last  joint  triangularly  oval.  Legs  slender, 
the  tibial  spurs  minute.  Form  at  least  moderately  convex,  body 
winged.  Elytra  either  not  at  all  striate,  or  those  near  the  suture 
alone  indicated  faintly.  Thorax  without  basal  incisures,  a smooth 
median  line  variably  present. 

This  group  is  equivalent  to  the  second  division,  A A,  indicated  in 
the  Monograph  of  Candeze.  Those  occurring  in  our  fauna  separate 
very  naturally  from  the  exotic  forms  by  having  the  carina  of  the 
hind  angles  of  the  thorax  short,  while  in  those  the  carina  is  pro- 
longed nearly  or  quite  to  the  anterior  angles.

GEO.  H.  HORN,  M.  D. 


The  species  known  to  inhabit  our  fauna  may  be  separated  by  the 
following  table. 

Elytra  faintly  striate  at  middle,  the  striae  distinctly  impressed  in  the  basal  de- 
clivity; antennae  and  legs  piceous;  surface  shining,  faintly  aeneous. 

restrictiiliis. 

Elytra  absolutely  without  striae  ; antennae  and  legs  pale. 

Surface  moderately  shining,  the  punctuation  extremely  indistinct;  each  ely- 
tron with  an  oblique  yellow  band  at  middle,  not  reaching  the  suture  and 
an  oval  apical  spot obliquatulus. 

Surface  subopaque,  the  punctuation  very  distinct,  especially  on  the  thorax; 
color  very  variable,  from  yellowish  testaceous  to  piceous,  with  intermediate 
maculate  forms  poctoralis. 

The  species  of  this  group  ai’e  snmll,  some  of  the  forms  of  pectoralis 
being  the  smallest  Elaterides  in  our  fauna. 

C.  restrictulus  Mann. — Oblong,  moderately  elongate  and  convex,  piceous, 
shining,  very  sparsely  pubescent ; antennae  piceous,  longer  than  the  head  and 
thorax,  slender  feebly  serrate,  joints  all  longer  than  wide  ; head  slightly  concave, 
not  closely  punctate  ; thorax  slightly  longer  than  wide,  widest  at  middle,  slightly 
narrowed  in  front,  sides  arcuate,  sinuate  in  front  of  the  hind  angles,  which  are 
slender,  acute,  divergent  and  carinate,  disc  convex,  finely  not  closely  punctate, 
the  median  line  faintly  smoother ; elytra  oblong  oval,  widest  at  middle,  humeri 
rounded,  disc  moderately  convex,  very  faintly  striate  near  the  middle,  the  striae 
impressed  in  the  basal  declivity,  at  the  sides  entirely  obliterated,  surface  moder- 
ately closely  punctate,  except  near  the  apex  ; prosternal  lobe  short,  mouth  ex- 
posed, the  sternum  moderately  convex,  sparsely  punctate  at  middle,  more  closely 
near  the  sides,  propleurse  shining,  moderately  closely  punctate;  metasternuni 
and  abdomen  similarly  punctate,  not  (dosely  nor  coarsely  ; legs  piceous,  the  tibiae 
and  tarsi  sometimes  paler.  Length  3.5  mm. ; .14  inch. 

In  the  male  the  last  ventral  segment  is  bisinuately  truncate  with  a 
median  tooth,  the  same  segment  of  the  female  is  similarly  truncate, 
but  in  a less  pronounced  manner. 

This  species  is  described  in  the  Monogra])h  of  Candeze  as  musculus 
Mann.,  but  a comparison  of  the  original  descriptions  will  show  that 
Dr.  Candeze  had  restrictulus  and  not  the  other  before  him.  Besides, 
a type  of  muscuhis  is  in  the  LeGonte  collection  from  Mannerheim. 
The  measurement  given  by  Candeze  is  also  incorrect  foi'  either  spe- 
cies, while  its  position  among  the  striate  species  is  certainly  mislead- 
ing. The  form  of  the  last  ventral  segment  is  not  found  in  any  other 
species  in  our  fauna.  In  habitus  the  species  resembles  Oedostethns 
femoralis,  but  in  the  latter  the  stride  are  more  distinctly  impressed, 
although  obliterated  at  the  side,  and  the  claws  have  the  basal  half 
dilated. 

Occurs  in  Alaska  (Mannerheim,  Ulke)  and  in  the  White  Mountain 
region  of  New  Hampshire  (Blanchard).

obliqiiatiilus  Mels. — Oblong,  moderately  convex,  pi ceo us,  thorax  some- 
what paler  in  color,  very  sparsely  pubescent,  antennfe  and  legs  testaceous;  an- 
tennse  slender,  feebly  serrate,  joints  all  longer  than  wide;  head  sparsely  punc- 
tate ; thorax  a little  wider  than  long,  slightly  narrowed  in  front,  widest  at  middle, 
sides  regularly  arcuate,  sinuate  in  front  of  the  hind  angles,  which  are  small, 
acute,  and  very  slightly  divergent,  the  carina  fine,  and.  when  seen  from  above, 
directed  nearly  straight  to  the  front,  disc  moderately  convex,  sparsely  equally 
punctate,  the  median  smooth  line  very  faint;  elytra  slightly  wider  than  the 
thorax,  humeri  very  little  oblique,  sides  regularly  arcuate,  widest  at  middle,  disc 
entirely  without  striae,  more  sparsely  and  finely  punctured  than  the  thorax,  color 
piceous,  on  each  elytron  an  oblique  yellowish  band  reaching  the  margin,  but  not 
the  suture,  an  oval  apical  spot  of  variable  size  also  yellow  ; prosternum  sparsely 
punctate,  and  with  two  transverse  impressions,  the  lobe  moderately  prominent, 
but  obtusely  rounded  in  front,  the  border  finely  beaded,  propleurae  shining,  more 
sparsely  and  finely  punctate  than  the  sternum  ; metasternum  minutely  and  in- 
distinctly punctate,  abdomen  more  densely  and  coarsely.  Length  2.25 — 2.75  mm. ; 
.09 — .11  inch. 

Usually  the  underside  of  the  body  is  much  paler  than  the  upper, 
especially  in  the  prothorax  and  the  elytral  epipleurie.  The  color 
and  markings  seem  to  be  very  constant,  and  vary  but  little  beyond 
that  caused  by  varying  degrees  of  maturity. 

The  males  have  a small,  densely  punctured  space  at  the  middle 
of  the  prosternum,  usually  more  pubescent,  but  never  as  distinct  as 
in  pectoralis. 

Distributed  from  Canada  aud  the  New  England  States  southward 
to  Virginia  and  westward  to  Iowa. 

C.  pectoralis  Say. — Oblong,  feebly  convex,  subopaque,  sparsely  finely  pu- 
bescent, color  variable  from  entirely  yellow  to  entirely  piceous ; antennte  slender, 
feebly  serrate,  joints  all  longer  than  wide,  yellowish  testaceous  ; head  moderately 
closely  punctate,  front  fiat;  thorax  usually  as  wide  as  long,  sometimes  slightly 
longer,  slightly  narrowed  in  front,  widest  at  middle,  sides  arcuate,  scarcely 
sinuate  in  front  of  the  hind  angles,  which  are  S7nall,  acute,  but  not  divergent, 
the  carina,  when  viewed  from  above,  turned  externally,  disc  very  distinctly  and 
rather  closely  punctate,  the  median  smooth  line  usually  evident;  elytra  slightly 
wider  than  the  thorax,  humeri  slightly  oblique,  sides  arcuate,  disc  without  strife, 
surface  less  distinctly  punctate  than  the  thorax;  prosternum  moderately  closely 
punctate,  transverse  impression  not  well  marked,  the  lobe  moderately  prominent, 
subtruncate  in  front,  propleurfe- punctate  similarly  to  the  sternum  ; metasteruum 
punctate  similarly  to  the  prosternum,  the  abdomen  much  more  finely  and  densely. 
Length  1.5 — 3 mm. ; .06 — .12  inch. 

The  males  of  this  species  have  a small,  but  densely  punctured 
s]iot  at  the  middle  of  prosternum  from  which  arises  a bunch  of  longer 
pubescence.  The  pubescence  is  often  absent,  except  in  well  preserved 
specimens. 

This  species  varies  greatly  in  color,  and  has  been  given  three 
names  in  consequence.  These  varieties  may  be  de.scribed  as  follows : 


28 


GEO.  H.  HORN,  M.  D. 


Y nr.  pectoralis  iiiiy. — Entirely  yellowish  testaceous  above  and  be- 
neath. Specimens  often  occur  with  a transverse  fuscous  fascia  behind 
the  middle  of  the  elytra,  which  extends  narrowly  along  the  suture  to 
the  apex. 

This  form  occurs  from  Massachusetts  to  California  and  Texas. 

Va.r.futilis  Lee. — This  does  not  differ  from  the  preceding  variety, 
except  in  its  smaller  size  and  with  apparently  a slightly  more  rugose 
thoracic  sculpture.  A subvariety  occurs  in  Arizona  entirely  piceous. 
'fhese  latter  are  the  smallest  specimens  seen  (.06  inch). 

Occurs  at  San  Diego  and  Owen’s  Valley  in  California,  and  also  in 
Arizona. 

Var.  inops  Lee. — Piceous,  elyti’a  with  an  indefinite  humeral  yellow 
spot,  a short  transverse  band  at  middle  adjacent  to  the  lateral  mar- 
gin, these  two  sometimes  united  along  the  margin,  a subapical  yellow 
space.  Specimens  often  occur  with  a median  discal  space  of  the 
thorax  yellowish. 

Occurs  in  California  and  Washington. 

Var. . — Entirely  piceous,  and  occasionally  with  the 

legs  darker  than  normal. 

This  is  known  to  me  from  the  extreme  northwest,  Washington, 
although  one  from  Iowa  has  merely  slightly  paler  humeri. 

From  the  localities  given  this  seems  to  be  the  most  widely  dis- 
tributed of  our  species.

APPENDIX. 

fflDOSTETHlTS  Lee. 

This  genus  does  not  seem  to  be  generally  known  to  collectors,  so 
that  but  few  specimens  have  ever  been  sent  me  for  determination.  It 
differs  from  Cryptohypnus  in  having  the  claws  abruptly  dilated  at 
basal  half  as  shown  in  fig.  8,  pi.  1.  The  prosternal  sutures  are 
arcuate,  but  in  a less  degree  than  in  the  species  of  Cryptohypnus 
with  sutures. 

Oe.  femoralis  Lee..  Revis.  Elat.  p.  489. 

This  is  the  only  species  known.  It  greatly  resembles  C.  restrictuhis, 
having  the  stride  of  elytra  feebly  distinct  on  the  disc  and  obliterated 
at  the  sides,  the  color  and  form  being  also  quite  similar.  The  max- 
illary palpi  are  rather  slender  and  similar  to  restrictulus. 

It  is  known  to  me  from  Canada,  westeim  Pennsylvania  and 
Colorado. 

.4KTHRACOPTERYX  u.  g. 

Frontal  margin  not  elevated,  confluent  with  the  edge  of  the  cly- 
peus.  Antennte  a little  longer  than  the  head  and  thorax,  joints  3-10 
feebly  serrate,  nearly  equal  in  length,  eleventh  longer,  second  shorter, 
first  joint  stout,  nearly  as  long  as  the  next  two.  Maxillary  palpi 
long,  the  last  joint  (of  both  palpi)  cultriform,  longer  than  the  two 
preceding  joints  together.  Thoracic  margin  acute,  when  seen  later- 
ally nearly  straight,  terminating  opposite  the  middle  of  the  eye; 
scutellum  oval,  slightly  transverse.  Elytra  oblong,  humeri  obliquely 
rounded,  body  apterous.  Prosternal  lobe  rather  short,  the  mouth 
exposed  beneath,  the  sutures  straight,  slightly  convergent  posteriorly, 
tip  of  prosternum  acute,  flexed  upward  toward  the  body-  Posterior 
coxal  plates  abruptly  dilated  at  inner  third.  Tarsi  as  long  as  the 
tibije,  the  first  four  joints  decreasing  gradually  in  length  and  not 
lobed,  claws  simple. 

The  above  description  briefly  defines  a form  which  it  is  by  no 
means  easy  to  place.  From  the  method  of  classification  adopted  by 
Dr.  Candeze,  which  assumes  the  form  of  the  front  as  the  character 
of  greatest  primary  moment,  the  genus  should  be  referred  to  the 
division  Corymbitites  and  to  the  group  Dirnites.  From  Dr.  Can- 
deze I have  received  the  following  note:  “ For  me  there  remains  no 
doubt,  after  a mature  examination,  that  it  can  be  placed  in  the 
Dimites,  where  it  will  form  a new  genus  related  to  Diadysis  (of 
Australia)  and  Asorno  (of  Patagonia)  which  I will  hereafter  j)lace 
in  the  Diiuites.” 


NORTH  AMERICAN  COLEOPTERA.

In  a sentence  immediately  preceding  he  writes:  “Its  head  is  the 
head  of  a Corymbitite,  but  the  coxte  !”  Here  is  the  point  at  issue. 
The  form  of  the  posterior  coxal  plates,  whether  abruptly  or  gradu- 
ally dilated  internally  seems  to  me  a character  of  greater  stability, 
and  therefore  more  reliable  as  a character  than  the  form  of  the  head. 
Therefore,  I must  at  this  time  differ  from  that  learned  entomologist, 
and  place  it  among  the  Cryptohypnites. 

In  the  latter  group  we  find  species  with  the  frontal  margin  scarcely 
distinct  from  the  clypeal  and  the  labial  palpi  exhibiting  a tendency 
to  elongate,  especially  in  the  last  joint. 

From  Cryptohypnus  the  genus  may  be  said  to  differ  by  the  form 
of  the  long  maxillary  palpi  terminated  by  a cultriform  joint. 

Science  owes  to  Mr.  T.  D.  A.  Cockerell  the  discovery  of  the  spe- 
cies on  which  the  genus  is  founded,  and  both  the  generic  and  specific 
names  are  due  to  his  suggestion.  Had  it  not  been  for  the  necessity 
of  quoting  the  letter  of  Dr.  Candeze  in  order  to  explain  why  I dif- 
fered from  him,  I would  have  preferred  to  have  elaborated  the  notes 
sent  me  by  Mr.  Cockerell  to  publish  them  under  his  name. 

A.  liieiiialis  n.  sp. — Oblong,  parallel,  moderately  convex,  piceous,  slightly 
shining,  sparsely  pubescent;  antenme  a little  longer  than  the  head  and  thorax, 
piceous,  feebly  serrate,  joints  all  longer  than  wide  ; head  sparsely  punctate,  front 
rather  flat,  the  frontal  ridge  not  continuous  across  the  front;  thorax  longer  than 
wide,  apex  feebly  emarginate,  widest  one-third  from  apex,  sides  moderately 
arcuate,  slightly  convergent  posteriorly,  feebly  sinuate  before  the  hind  angles, 
which  are  acute,  not  long  nor  divergent,  distinctly  carinate,  disc  moderately 
convex,  median  line  feebly  impressed  posteriorly,  without  basal  incisures,  sur- 
face equally  punctate,  moderately  coarsely,  but  not  closely;  elytra  not  wider 
than  the  thorax  in  front,  oblong  oval,  humeri  very  oblique,  disc  striate,  strije 
punctured,  intervals  flat,  irregularly  biseriately  punctate  and  somewhat  wrinkled, 
especially  at  base ; prosternal  lobe  not  prominent,  irregularly  arcuate  in  front, 
the  edge  not  beaded,  surface  coarsely  not  closely  punctate,  apical  mucro  very 
oblique,  propleurse  less  coarsely  and  less  closely  punctate;  metasternum  and 
abdomen  still  less  closely  punctate  and  more  shining,  the  last  segment  more 
coarsely  and  closely  ; legs  piceous,  tarsi  usually  paler.  Length  6.5  mm. ; .26  inch 
PI.  1,  figs.  6,  7. 

Collected  by  Mr.  T.  D.  A.  Cockerell  at  West  Cliffe,  Custer  County, 
Colorado,  at  an  elevation  of  7000  feet  and  over.

XEW  SPEEIES  AND  MISt'EEEANEOES  NOTES. 

BY  GEO.  H.  HORN,  M.  D. 

The  few  new  species  described  below  are  mostly  of  curious  forms, 
or  of  groups  not  previously  represented  in  our  fauna.  Others  have 
interest  in  their  relationship  with  Mexican  forms,  while  several  are 
indicated  as  inhabitants  of  our  fauna  known  previously  from  more 
tropical  regions  to  the  south. 

A few  synonyms  have  been  given  which  need  no  special  comment. 

PTEROSTICHUS  Bon. 

P.  (Hyperphes)  iiiaiiis  n.  sp. 

This  name  is  suggested  for  a species  closely  ailed  to  angushis,  Imt 
of  rather  less  parallel  form  and  somewhat  larger  size,  and  always  of 
darker  color.  The  head  is  broader,  and  more  distinctly  narrowed 
behind  the  eyes,  which  are  larger  and  more  convex.  The  thorax  is 
more  distinctly  narrowed  behind  from  being  somewhat  more  arcuate 
in  front.  The  basal  impressions  are  deeper  and  longer,  while  the 
basal  marginal  line  is  very  short  (in  angustus  extending  across  the 
entire  base).  The  elytra  are  more  depressed,  the  sides  more  arcuate. 
The  under  side  does  not  present  any  essential  differences.  Length 
10-12  min.;  .-10-.48  inch. 

In  the  male  the  hind  trochanter  is  always  two-thirds  the  length 
of  the  femur,  and  sometimes  slightly  longer  than  that,  the  apex  very 
acute,  while  in  angmtus  the  same  member  is  rarely  more  than  half 
the  length  of  the  femur  and  obtuse  at  tip. 

The  essential  differences  from  angustus  are — larger  size  and  less 
parallel  form,  prothoracic  impressions  deeper  and  longer,  basal  mar- 
ginal line  here  almost  absent,  except  at  hind  angles,  and  finally  the 
form  of  the  male  hind  trochanters. 

Occurs  in  Washington,  Nevada,  and  as  far  south  as  Placer  County, 
California. 

P.  (Hyperphes)  caligaiis  n.  sp. 

Very  like  angustus,  but  still  more  slender  and  elongate.  Castane- 
ous,  shining,  elytra  very  finely  alutaceous ; head  relatively  larger, 
frontal  impressions  moderately  deep,  optic  prominences  normally 
large,  the  eyes  very  small ; thorax  longer  than  wide,  narrower  at 
base,  sides  very  feebly  arcuate,  slightly  sinuate  in  front  of  the  hind 
angles,  which  are  sharply  rectangular,  median  impression  moderately 
deep,  extending  to  base  and  nearly  to  apex,  basal  impressions  sitigle. 


NORTH  AMERICAN  COLEOPTERA.

moderately  deep,  arcuate,  liasal  marginal  line  entirely  absent;  elytra 
oblong,  nearly  2mrallel,  humeri  slightly  dentate,  surface  moderately 
deeply  striate,  strije  obsoletely  punctate,  intervals  very  slightly  con- 
vex ; beneath  similar  in  color,  abdomen  finely  alutaceous,  indistinctly 
punctate  at  sides  in  front.  Length  10-11  mm. ; .40-.44  inch. 

In  the  male  the  hind  trochanter  is  about  half  as  long  as  the  femur 
and  obtuse  at  tip. 

Two  sjiecimens  have  been  examined,  taken  by  Mr.  L.  E.  Rick- 
secker  at  ISylvania,  Cal. 

This  species  is  evidently  closely  related  to  longissimus  Bates  (Biol. 
Cent.  Am.  i,  p.  81,  pi.  iv,  fig.  6),  although  that  species  is  said  to  have 
non-dentate  humeri.  Direct  comparison  will  be  necessary  to  indicate 
the  real  differences,  as  it  can  hardly  be  supiiosed  that  an  almost 
blind  species  from  middle  California  is  identical  with  one  from 
Guatemala. 

The  two  species  above  described  constitute,  with  migustus,  a small 
group  of  Pterostichus,  characterized  especially  by  a very  narrow, 
almost  parallel  form.  All  have  small  eyes,  although  they  vary  in 
size  in  the  three  species.  Of  the  three  itianis  has  the  largest  eyes, 
and  caligans  the  smallest. 

The  characters  separating  them  may  be  tabulated  in  the  following 
manner : 

Thorax  witli  two  distinct  linear  basal  impressions,  the  basal  marginal  line  entire ; 
hind  trochanters  of  'J,  longer  than  half  the  femur  and  very  acute  at  tip; 

scutellar  stria  rarely  well  marked,  often  absent inaiiis. 

Thorax  with  two  basal  impressions,  the  outer  quite  short,  basal  marginal  line 
variable,  sometimes  entire,  often  visible  near  the  angles  only;  hind  trochan- 
ters of  male  half  as  long  as  the  femur  and  obtuse  at  tip;  scutellar  stria  dis- 
tinct  august  us. 

Thorax  with  but  one  basal  Impression,  the  basal  marginal  line  entirely  wanting; 
hind  trochanters  of  male  as  in  angustus ; scutellar  stria  distinct. .caligaiis. 

The  last  species  resembles  in  a marked  degree,  small  sj^ecimens 
of  Stenoraorpkus  rufipes. 

I*.  Blaiieliardi  n.  sp.— Form  rather  robust,  piceous,  shining,  legs  and 
antennfe  rufo-testaceous  Head  smooth,  frontal  impressions  short;  thorax  cor- 
date, wider  than  long,  sides  strongly  arcuate,  rather  deeply  sinuate  posteriorly 
the  hind  angles  rectangular,  surface  smooth  and  shining,  without  punctures  at 
base,  median  line  fine  and  entire,  basal  impressions  single,  deep,  straight,  ex- 
tending nearly  a third  to  the  front,  basal  marginal  line  entire  and  very  distinct ; 
elytra  rather  broadly  oval,  more  acute  behind,  moderately  convex,  humeri  not 
dentate,  striae  rather  deep,  distinctly  punctured,  the  sides  of  the  intervals  slightly

erenate,  the  intervals  slightly  convex,  a dorsal  puncture  on  the  third  stria  behind 
the  middle;  body  beneath  smooth,  shining,  prosternuin  not  margined  at  tip. 
Length  6 mm. ; .24  inch. 

This  is  the  smallest  species  outside  of  some  in  the  Cryobius  series 
known  to  me  in  our  fauna.  It  has  the  general  aspect  of  honedus, 
although  less  convex,  and  somewhat  more  acute  posteriorly.  It  may 
be  known  from  that  species  by  the  following  j)oints : 

Thorax  punctate  at  base,  without  marginal  line,  basal  impressions  arcuate;  striae 

not  punctate lioiiestiis. 

Thorax  smooth  at  base,  marginal  line  entire,  basal  impressions  straight ; striae 
punctate,  intervals  erenate ISlaiiicliardi. 

The  unique  before  me  was  collected  by  Mr.  F.  Blanchard  at 
Highland,  North  Carolina. 

BEMBIDIUin  Latr. 

B.  haplogonum  Chd.  is  a variety  of  erosimi  Motsch.  {mannerheimii

D.  cordicollis  n.  sp. — Form  rather  depressed,  pieeous  to  castaneous  in 
color,  shining,  the  darker  specimens  with  a faint  feneous  lustre,  anteunpe  and 
legs  always  paler.  Head  smooth,  frontal  impressions  short,  in  some  specimens 
two  punctiform  fovese  between  the  eyes;  thorax  rather  more  than  half  wider 
than  long,  broadly  cordate,  sides  arcuate  and  gradually  narrowing  to  the  base, 
the  hind  angles  entirely  obliterated,  disc  feebly  convex,  smooth,  rarely  feebly 
transversely  wrinkled,  basal  impressions  short,  but  rather  broad;  elytra  subde- 
pressed, oblong  oval,  strige  fine  not  punctate,  intervals  slightly  convex  and 
smooth  , or  flatter  and  feebly  alutaceous  9,  the  usual  rows  of  punctures  on 
the  alternate  intervals ; body  beneath  smooth,  less  shining  than  above,  proster- 
uum  not  margined  at  tip.  Length  7.5 — 8.5  mm. ; .30 — .34  inch. 

In  both  sexes  there  is  but  one  anal  puncture  on  each  side.  The 
male  is  more  shining  than  the  female,  and  the  elytral  intervals  more 
convex.  The  last  ventral  of  the  male  is  more  obtusely  arcuate  at 


NORTH  AMERICAN  COLEOPTERA.

apex,  that  of  the  female  being  much  more  acute  and  slightly  ele- 
vated in  an  obtuse  carina  near  the  middle.  The  male  has  a few 
squamules  on  the  anterior  tarsi.  Tibiie  straight  in  both  sexes. 

This  species  is  the  most  depressed  of  any  in  our  fauna,  and  has 
the  thorax  much  more  narrowed  behind,  resembling  a diminutive 
Polpochile  capitata.  There  is  no  depression  of  the  lateral  margin  of 
the  thorax,  as  is  usual  in  our  heretofore  described  species. 

Occurs  from  Fort  Yuma  eastward  to  Tucson,  Ariz.  (Wickham.) 

I>.  crassicollis  n.  sp. — Form  robust,  convex,  piceous,  shining,  without 
trace  of  metallic  surface  lustre;  antennae,  palpi,  and  usually  the  labrum,  casta- 
ueous;  head  impunctate,  frontal  impressions  very  short;  thorax  quadrate,  a 
little  wider  than  long,  slightly  narrowed  at  base,  widest  one-third  from  apex 
sides  regularly  arcuate,  margin  not  depressed,  hind  angles  obtusely  rounded,  disc 
convex,  median  impression  faint  and  short,  basal  impressions  broad,  but  shallow 
and  vague;  surface  smooth,  with  a few  longitudinal  wrinkles  at  base;  elytra  not 
wider  than  the  thorax,  sides  feebly  arcuate,  disc  convex,  finely  striate,  stri®  not 
punctate,  intervals  smooth,  very  feebly  convex,  the  inner  sides  of  3-6-8  with 
the  usual  punctures  fine  and  rather  indistinct;  body  beneath  slightly  paler, 
shining,  prosternum  not  margined  at  tip,  but  with  two  (usually)  prominent  bris- 
tles on  each  side;  abdomen  very  sparsely  punctate,  coarser  punctures  on  the 
intercoxal  process.  Length  12.5  mm. ; .50  inch. 

Although  reasonably  certain  that  both  sexes  are  before  me  in  the 
live  specimens  examined,  no  well  marked  sexual  difierences  have 
been  observed.  The  last  ventral  segment  bears  two  setie  on  each 
side.  The  middle  tibise  are  not  longer  than  the  anterior,  are  broader 
toward  the  tip,  slightly  arcuate  and  beset  on  the  outer  side  with  short 
spinules.  The  posterior  tibise  are  also  very  slightly  arcuate.  The 
anterior  tarsi  are  not  furnished  with  squamules. 

This  species  is  evidently  very  closely  allied  to  acmopoides  Bates 
(Biol.  Cent.  Am.  Col.  i,  p.  63),  which  is  described  as  having  the 
elytra  cupreous  and  the  sides  of  the  thorax  straight  and  not  arcuately 
narrowing  as  in  the  present  species. 

It  is  the  most  robust  and  convex  species  in  our  fauna,  quite  unlike 
our  others,  and  resembling  an  Acinopus  more  nearly  than  Discoderus. 

Occurs  in  southern  Arizona.

tional  species  of  Anatrichis,  two  from  the  East  Indies,  the  third 
Australian.  Four  species  are  referred  to  Oodiellns,  one  from  Mexico 
and  three  from  Brazil.  Mr.  H.  W.  Bates  describes  as  Anatrichis 
two  more  from  Mexico  which  must  be  referred  to  Oodiellns,  whether 
regai-ded  as  a section  or  a valid  genus.  The  characters  of  the  latter 
genus  are  derived  entirely  from  the  mouth  parts  and  do  not  seem  to 
be  of  sufficient  moment  for  generic  separation,  as  Mr.  Bates  has 
remarked,  an  opinion  in  which  I fully  concur. 

In  his  posthumous  work  Chaudoir  fails  to  mention  a character 
of  the  male  of  Anatrichis  observ'ed  by  LeConte  (Trans.  Am.  Philos. 
Soc.  1853,  X,  p.  391).  The  middle  tibiae  have  on  the  inner  side  at 
the  lower  third  an  emargination  resembling  somewhat  that  of  the 
front  tibia.  This  character  is  not  observed  in  the  only  male  of 
Oodinus  examined.  It  would  be  interesting  to  know  what  value  this 
has,  in  addition  to  those  given  below,  for  the  separation  of  Anatrichis 
and  Oodinus. 

There  is,  however,  one  character  more  easily  seen  which  will  sepa- 
rate the  species  of  the  two  divisions  without,  to  my  mind,  having 
any  greater  weight  than  those  u.sed  by  Chaudoir. 

As  far  as  can  be  gathered  from  descriptions  the  species  separate 
in  the  following  manner: 

Elytral  strife  distinctly  punctate S.  G.  Aiiali'icliis. 

Elytral  strife  fine  and  simple S.  G.  Oodinus. 

The  former  is  represented  in  our  fauna  by  A.  minuta  Dej.,  with 
shining,  finely  punctate  surface,  the  basal  impressions  of  the  thorax 
deep  but  short.  The  apex  of  the  prosternum  is  distinctly  margined. 

The  subgenus  Oodinus  is  represented  by  two  species. 

Form  more  broadly  oval  than  A.  minuta,  surface  more  opaque;  first  and  second 
elytral  striae  uniting  at  base,  terminating  together  in  an  ocellate  fovea  ; 

prosternum  not  margined  at  tip l>icea  Mots. 

Form  oblong,  recalling  a diminutive  Lachnocrepis  parallela,  surface  shining; 
strife  all  partly  obliterated  at  base,  an  ocellate  fovea  near  the  end  of  the 
second  ; prosternum  margined  at  tip obloiiga  n.  sp. 

The  genus  Anatrichis  is  properly  considered  feminine  in  its  termi- 
nation by  LeConte,  Chaudoir  and  the  Catalogus.  Mr.  Bates,  how- 
ever, appears  to  regard  it  as  masculine  from  his  specific  names.

tion and  extremely  minutely  aliuaceous ; the  median  line  of  the  thorax  is  ex-

treniely  fine  and  the  basal  impressions  very  shallow  and  vague;  the  elytral  stria- 
are  fine  and  sliarp,  without  punctures,  the  intervals  flat,  minutely  alutaceous, 
the  third  with  the  tvvo  dorsal  punctures  behind  the  middle;  the  prosternum  is 
obtuse  at  tip  and  without  marginal  line.  Length  6 mm. ; .24  inch. 

The  specimen  before  me  is  a male.  The  first  four  joints  of  the 
anterior  tarsi  are  dilated  as  in  viinuta,  but  the  middle  tibiae  are  simple. 

Occurs  in  our  fauna  in  southern  Texas  and  Central  America  to 
Santarem,  in  Brazil. 

A.  obloiiga  n.  sp. — Oblong,  piceous-hlack,  somewhat  shining;  antennse  pi- 
ceous,  the  three  basal  joints  and  palpi  rufo-testaceous ; head  without  frontal  im- 
pressions, the  surface  extremely  minutely  alutaceous:  thorax  about  one-third 
wider  at  base  than  long,  sides  arcuately  narrowing  to  apex,  median  line  very 
finely  impressed,  the  basal  impressions  deep  but  short,  surface  minutel.v  aluta- 
ceous; elytra  oblong,  sides  feebly  arcuate,  strife  sharply  impressed  but  not  punc- 
tate, not  quite  reaching  the  base,  an  ocellate  fovea  near  the  base  of  the  second, 
intervals  flat,  verv  minutely,  sparsely  punctate  and  finely  alutaceous,  the  dorsal 
punctures  of  the  third  interval  indistinct;  body  beneath  more  shining  than 
above,  the  prosternum  with  marginal  line  at  tip  ; legs  castaneous.  Length  6 mm. ; 
.24  inch. 

This  species  is  evidently  closely  related  to  lougula  Bates,  and  may 
even  be  the  same,  although  I can  hardly  apply  his  description  of  the 
thorax  to  my  specimen  : “ transversim  quadrate,  antice  paullo  magis 
quam  postice  angustato.” 

The  surface  sculpture  is  so  minute  that  a moderately  high  power  is 
required  to  detect  the  alutaceous  structure  and  the  elytral  punctures. 

One  specimen  9 » Texas  near  the  lower  Rio  Grande. 

OODEN  Bon. 

From  the  description  given  by  Chaudoir,  in  1882,  it  seems  that  the 
species  known  to  us  as  texaims  Lee.  is  the  same  as  mexicanus  Chev. 

0.  duodecimstriafm  Chev.  According  to  Chaudoir,  who  has  ex- 
amined types,  this  name  should  replace  0.  Lecontei  did.  in  our  lists. 

STEXOC'REPIS  Chd. 

A specimen  in  my  cabinet  collected  near  the  lower  Rio  Grande 
of  Texas  seems  to  be  referable  to  S.  chalcas  Bates  {chalcoclirous  Chd.), 
Biol.  Cent.  Am.  Col.  i,  )i.  47.  It  is  nearly  as  elongate  as  Lachno- 
crepis,  but  with  a form  of  thorax  as  in  our  Oodes  s.s.  The  striie 
are  very  distinctly  punctate  and  the  sides  of  the  intervals  crenate. 
The  under  side  of  the  body  is  iridescent,  the  sides  of  the  metaster- 
num with  coarse  punctures,  the  first  two  ventral  segments  at  the 
sides  with  very  coarse  punctures.  Prosternum  not  margined  at  tip. 
On  the  elytra  the  seventh  stria  is  replaced  by  a row  of  extremely 
indistinct  fine  punctures.

(iEO.  H.  HORN,  M.  D. 


If  the  insect  before  me  really  represents  S.  chalcas,  and  of  this  I 
have  very  little  doubt,  the  genus  seems  to  me  intermediate  between 
(dodes  s.s.  and  Lachnocrepis.  With  the  former  it  agrees  in  having 
the  first  foxir  joints  of  the  anterior  tarsi  of  the  male  dilated  and 
papillose  beneath,  although  the  posterior  tarsi  are  not  pubescent  be- 
neath. The  mode  of  dilatation  of  the  tarsi  is  the  same  as  in  Lach- 
)iocre])is. 

It  seems  to  me  that  Chaudoir  was  not  true  to  his  own  methods  in 
uniting  Stenocrepis,  Stenous  and  Crossocrepis  as  sections  under  the 
first  name.  If  it  be  advisable  to  se[)arate  any  of  them  from  Oodes, 
it  seems  to  me  desirable  to  retain  Stenocrepis  apart,  while  the  other 
two  could  be  very  well  united. 

In  Oodes  s.s.  the  entire  under  side  of  the  body  is  comparatively 
smooth,  in  the  others  above  mentioned  the  sides  of  the  metasternum 
and  the  metapleurse,  and  usually  the  sides  of  the  first  two  ventral 
segments  are  very  coarsely  punctate. 

EUPHORTIC’US  Horn. 

E.  occitleiitalis  u.  sp. 

This  name  is  proposed  for  a species  occurring  near  Los  Angeles, 
Cal.,  resembling  jm/6escens  Dej.,  and  differing  in  the  following  manner: 

Surface  more  brilliantly  aeneous.  Elytral  striae  very  faint,  the  punctures  fine, 
ronucl  and  rather  distant,  intervals  flat,  punctulate.  Length  4 mni. ; .16  inch. 

The  punctures  of  the  elytral  stripe  do  not  extend  beyond  the  mid- 
dle in  either  species,  but  in  puhescens  they  are  large  and  more  closely 
placed  than  their  own  diameters.  On  the  other  hand  the  fine  punc- 
tures of  the  intervals  are  sparser  and  less  distinct  in  occidentalis  than 
\\\  puhescens.  In  the  latter  species  the  tibipe  are  always  jialer  than 
the  feuKji-a,  in  the  former  they  are  as  dark  as  the  femora. 

PCECIEOEHRUK  Bouv. 

To  this  genus  should  be  referred  the  species  described  by  me  as 
Htethon  errans. 

Poecilochrus  may  be  distinguished  from  Stethon  by  the  straight 
prosternal  sutures.  In  both  genera  the  metasternum  has  a short 
groove  limited  by  an  elevated  line  begining  at  the  inner  side  of  the 
middle  coxae  and  directed  backward  in  a straight  line. 

Dronueolus  pnsillus  Horn. — This  species,  while  very  unlike  our 
others,  has  a number  of  related  forms  in  the  Mexican  fauna.  They 
nearly  all  have  the  |)rosternal  sutures  very  finely  grooved  and  the

propleural  triangle  is  in  absolute  union  with  the  prosternuin,  or  very 
nearly  so.  In  facies  they  more  nearly  resemble  Thambus  than 
Dromseolus. 

I have  already  called  attention  to  the  fact  that  in  Microrhagus 
(Trans.  Am.  Ent.  8oc.  1886,  p.  35)  the  pubescent  fovea  on  the  last 
or  penultimate  segment  was  a sexual  character.  While  the  fact  is 
correct,  I have  wrongly  attributed  the  possession  of  it  to  the  male. 
Since  then  the  same  character  has  been  elsewhere  observed,  Enio- 
mophthalrnus  americanus,  where  the  female  has  the  fovea  and  the 
male  a small  tubercle. 

In  the  table  of  Microrhagus  (Mon.  des  Eucnemides)  under  “23,” 
p.  528,  two  series  of  species  are  separated,  the  one  with  femora 
scarcely  darkened,  the  other  with  them  decidedly  brown  or  nearly 
black.  Fortunately  but  three  species  are  sepai’ated  under  the  last 
<livision,  otherwise  confusion  might  result,  as  the  color  of  the  legs,  as 
above  defined,  has  no  value  whatever. 

CLiADUS  Bonv. 

While  this  genus  of  Eucnemidm  is  not  represented  in  our  fauna, 
belonging  exclusively  to  the  central  American  region,  I have  thought 
it  worth  while  to  call  attention  to  it,  as  but  few  interested  in  purely 
North  American  entomology  will  see  the  illustration  of  the  extra- 
ordinary modification  of  the  mouth  parts  published  by  me  in  the 
“ Biologia  Centrali-Arnericana.” 

The  accompanying  illustration  is  the  same  as  used  in  that  publi- 
cation, and  shows  the  maxilla  of  the 
right  side  uncovered  by  the  removal 
of  the  half  of  the  mentum  and  on  the 
right  side  of  the  cut  the  remaining  half 
of  the  mentum.  The  maxillary  paljms 
is  transformed  into  two  long  stalks 
bearing  ciliate  branches.  The  labial 
palpus  is  ])rimarily  divided  into  four 
branches,  two  of  which,  the  first  and 
third,  are  again  divided  ; all  with  ciliate 
branches.  The  ribbon-like  prolonga- 
tion behind  the  palpar  modification  is 
a modified  ligula.  The  two  lobes  of  the 
maxilla  are  sufficiently  well  shown  in  the  cut  and  need  no  explana- 
tion.

GEO.  H.  HORN,  M.  D. 


The  Utility  of  this  modification  in  a family  in  which  the  mouth- 
parts  are  otherwise  quite  constant  is,  for  me,  beyond  explanation. 
The  Eucnemida3  seem  to  live  their  short  lives  by  the  ingestion  of 
liquid  food,  the  juices  of  decaying  wood  and  similar  matters,  so  that 
this  modification  may  assist  capillary  action,  although  there  does  not 
seem  any  reason  why  Cladus  should  be  so  provided  and  the  closely- 
allied  Fornax  not. 


PAL,.«OXEi\lJS  u.  g. 

This  new  generic  name  is  suggested  for  a species  described  by  me 
some  years  ago  as  Cryptosto^na  Dohrnii. 

At  that  time  I had  seen  no  specimen  of  Cryptostoma,  and  the 
failure  to  record  several  important  characters  in  the  Bonvouloir  de- 
scription caused  me  to  refer  my  specimen  to  that  genus.  Through 
the  kindness  of  Mr.  Ed.  Fleutiaux  I have  been  enabled  to  study  a 
specimen  of  C.  spmicorne,  and  can  now  indicate  the  differences : 

Paheoxenns. — Antennfe  simple  in  both  sexes,  the  last  two  joints 
shorter,  the  terminal  joint  broader  than  long,  squarely  truncate,  but 
chisel-shaped  on  its  terminal  edge.  Mesosternum  oblique,  broadly 
grooved.  Eyes  longer  in  their  vertical  diameter  and  without  dis- 
tinct supra-orbital  ridge. 

Cryptostoma. — Antennse  with  a spiniform  process  from  the  base  of 
third  joint  % , or  with  a spine  on  the  posterior  side  near  apex  of 
first  joint  9 , the  terminal  joint  longer  than  the  preceding  and  either 
slender  % , or  very  acutely  oval  at  tip  9 . Mesosternum  prominent, 
the  sides  elevated,  forming  the  usual  receptacle  for  the  tip  of  proster- 
num. Eyes  oval,  very  little  longer  vertically  and  with  distinct 
supra-orbital  ridge. 

PHEXGODES  Latr. 

I*.  |»icicollis  n.  sp. — Head  piceous  black,  deeply,  arcuately  impressed  be- 
tween the  eyes,  and  longitudinally  toward  the  clypeus,  in  front  of  the  transverse 
groove  coarsely  and  closely  punctate,  behind  it  coarsely  longitudinally  strigose 
and  punctate;  antennie  not  half  as  long  as  the  body,  piceous-black.  the  branches 
fuscous,  the  basal  joint  yellow:  eyes  relatively  small  ; thorax  about  one-half 
wider  than  long,  apex  arcuate,  sides  arcuate  near  the  front,  then  parallel  to  base, 
lateral  explanate  border  moderate,  disc  moderately  convex,  a round  fovea  each 
side  near  the  apex,  a slight  longitudinal  impression  at  middle  nearer  the  base, 
surface  shining,  rather  finely  not  closely  punctate,  more  distinctly  near  the  sides, 
sparsely  flavo-pubescent,  color  piceous,  with  the  entire  limb  narrowly  testaceous; 
scutellum  piceous;  elytra  yellowish  testaceous,  gradually  fuscous  toward  the 
apex  ; abdomen  yellowish  testaceous,  the  segments  piceous  along  their  anterior 
b(!rder,  beneath  piceous,  shining,  the  border  and  last  segment  pale;  ineso-meta-

sternum  ])iceous,  sliiuing,  punctate;  legs  yellowish  testaceous,  the  coxse  and  tarsi 
piceous.  Length  10.5  mm. ; .42  inch. 

The  explamite  border  of  tlie  thorax  is  broader  than  in  fiisciceps, 
but  less  explanate  than  \n  plnmosa,  frontalis,  or  laticollis.  It  should 
be  associated  with  fasciceps  mu]  Sallei  from  the  antennte  being  shorter 
than  half  the  body.  It  is  the  only  species  in  our  fauna  with  a pice- 
ous thorax. 

One  specimen,  collected  in  Ramsey  County,  Minn.,  and  given  me 
by  ]\Ir.  Otto  Lugger. 

I*,  pltiiuosa  Oliv. 

The  type  of  this  species,  which  is  now  in  the  British  Museum,  was 
collected  by  M.  Francillon  in  Georgia.  An  examination  of  it  in 
comjiarison  with  frontalis  shows,  among  other  characters,  much 
smaller  eyes,  i.e.,  the  eyes  when  seen  from  above  are  scarcely  wider 
than  half  the  distance  to  the  median  line  of  the  head,  while  in  fron- 
talis the  eyes  are  fully  as  wide  as  the  distance  to  the  middle. 

ERG.ITKS  Serv. 

E.  neomexicanus  Casey  is  an  absolute  synonym  of  E.  spiculatus 
Lee.  The  characters  given  to  separate  the  two  are  purely  individual, 
and  are  seen  in  specimens  from  Vancouver  as  w'ell  as  in  those  from 
New  Mexico. 

ACOWA  Casey. 

The  reference  of  this  genus  to  the  Melolonthine  series  is  a mistake. 
It  is  plainly  a Laparostict,  and,  like  Pleocoma,  has  the  mouth-parts 
of  the  male  (the  only  sex  known)  much  reduced,  and  in  a manner 
similar  to  Pleocoma.  Its  position  in  our  series  is  after  the  latter 
genus. 

Polyphylla  speciosa  Casey,  described  from  the  female,  is  the  female 
of  clecemlineata  Say. 

EEEOnES  Esch. 

E.  Wiclihaini  u.  sp.— Elongate,  black,  shining,  elytra  with  slight  velvety 
lustre;  antennie  a little  longer  than  the  head  and  thorax,  the  third  joint  de- 
cidedly longer  than  the  next  two;  hea<l  sparsely  punctate  ; thorax  suhquad rate, 
a little  wider  than  long,  slightly  narrowed  behind,  sides  slightly  arcuate  in  front, 
oblique  posteriorly,  anterior  angles  not  everted  ; disc  moderately  convex,  sparsely, 
yery  finely  and  indistinctly  punctate;  elytra  elongate  oval,  attenuate  posteriorly, 
disc  convex  with  rows  of  extremely  fine,  indistinct  punctures;  body  beneath 
more  shining  than  above,  the  abdomen  transversely  wrinkled.  Length  27  mm. 
including  cauda  33  mm. ; 1.08  inch.;  1.. 32  inch.  PI.  1.  fig.  12.  ■

^[ale. — Elytra  prolonged  in  a narrow  eauda,  which  is  channeled  beneath  and 
curved  slightly  downward  at  tip;  aiiterior  femora  with  a small  tooth  near  the 
knee,  the  tibia  narrowed  at  base;  middle  and  posterior  femora  simple;  posterior 
tibise  slightly  arcuate,  narrow  at  basal  half,  rather  abruptly  dilated  in  apical 
half,  in  which  part  the  surface  is  quite  asperate. 

This  species  belongs  in  the  series  near  E.  lucoe  Lee.,  but  the  males 
may  be  easily  known  by  the  sexual  characters  in  the  front  and  hind 
tibite  of  Wickhami,  which  do  not  exist  in  the  other.  The  anterior 
angles  are  quite  acute  forward  or  even  faintly  everted  in  luc(e,  and 
in  the  male  the  elytra  are  vaguely  sulcate,  with  coai’se  obsolete  punc- 
tures. The  legs  are  relatively  longer  than  in  any  other  Eleodes 
known  to  me. 

Collected  by  Mr.  H.  F,  Wickham  near  Tucson,  Ariz.,  and  named 
as  an  evidence  of  my  appreciation  of  his  labors  in  that  region. 

E.  longipilosa  n.  sp. — Piceous-black,  moderately  shining,  surface  sparsely 
clothed  with  long,  black,  flying  hairs;  head  coarsely  not  closely  punctate, 
smoother  at  middle;  thorax  about  a fourth  wider  than  long,  sides  arcuate  in 
front,  obliquely  narrowed  posteriorly,  disc  moderately  convex,  coarsely  sparsely 
irregularly  punctate,  apex  slightly  emargiuate,  anterior  angles  subacute,  but  not 
everted;  elytra  elongate  oval,  more  attenuate  posteriorly,  disc  feebly  convex, 
very  vaguely  sulcate,  surface  irregularly  sparsely  muricate,  the  two  grooves 
nearest  the  suture  coarsely  punctate ; propleurse  wrinkled  and  sparsely  muricate  ; 
abdomen  with  first  three  segments  very  coarsely  punctate  and  rugose,  the  last 
two  segments  much  smoother.  Length  19  mm. ; with  cauda,  21.5  mm. ; .76 — .86 
inch.  PI.  1,  fig.  13. 

Male. — Elytra  prolonged  at  tip  in  a cauda,  the  apices  slightly  separated,  beneath 
grooved. 

This  species  is  related  to  candifera,  and  like  it  has  the  femoi-a  not 
toothed  in  either  sex.  The  general  form  is  the  same  as  in  that  spe- 
cies, but  the  elytra  are  much  less  evidently  striate.  It  is,  however, 
especially  remarkable  in  the  rather  long  flying  hairs  of  the  surface, 
which  extend  also  on  the  legs  even  to  the  humeral  joint  of  the  tarsus. 

Collected  in  Humboldt  Valley,  Nev.,  by  IVIr.  Krause,  and  kindly 
given  me  by  Mr.  L.  E.  Ricksecker. 

EPICAIITA  Redt. 

E.  straba  n.  sp. — Black,  subopaque,  sparsely  clothed  with  short  brownish 
and  iiiconspicous  pubescence.  Antennse  black,  setaceous;  head  broadly  oval, 
densely  punctate,  occiput  rather  deeply  impressed  ; eyes  obliquely  oval,  prolonged 
in  an  acute  angle  toward  the  occiput,  limited  behind  by  a smooth  depressed 
space;  thorax  quadrate,  narrowed  near  the  apex,  closely  punctate,  a median  lon- 
gitudinal impression,  and  another  less  distinct  on  each  side  arcuate;  elytra 
closely  punctate  scabrous,  subopaque;  body  beneath  black,  shining,  puuctulate; 
legs  black.  Length  7 — 8 mm.;  .28 — .32  inch.  PI.  1,  fig.  10.

111  the  males  the  anterior  tibiae  have  two  terminal  spurs,  the  tibiae 
flattened  on  the  inner  side  and  densely  silken  pubescent.  In  the 
female  the  anterior  tibiae  are  not  flattened  on  the  inner  side  and  have 
a narrow  pubescent  line. 

This  species  belongs  to  a small  group  containing  Rileyi  and  cavi- 
ceps,  both  of  which  have  peculiarly  formed  eyes  limited  behind  by 
a smooth  dejiressed  space.  This  is  the  only  species  known  to  me 
with  the  eyes  oblique  and  acute  above. 

Collected  by  Mr.  W.  G.  Wright  at  San  Bernardino,  Cal. 

E.  9Ierkeliaiia  n.  sp. — Form  slender,  piceous,  subopaque,  not  densely 
clothed  with  short  cinereous  pubescence,  entire  head,  antenme  and  legs  pale 
rufo-ferruginous.  Antenn®  filiform  ; head  punctate,  less  closely  along  the  mid- 
dle and  less  densely  than  the  thorax,  the  median  line  finely  impressed,  occiput 
entire;  thorax  longer  than  wide,  sides  feebly  arcuate,  slightly  narrowed  at  base, 
apical  third  obliquely  narrowed,  median  line  impressed,  a little  deeper  posteriorly, 
surface  densely  punctulate;  elytra  closely  luinctulate,  somewhat  scabrous;  body 
beneath  more  shining  than  above,  the  pubescence  longer,  although  less  dense  on 
the  abdomen  ; legs  rather  shining,  sparsely  punctate,  scarcely  pubescent.  Length 
8.5  mm. ; .34  inch. 

This  species  belongs  to  the  series  with  filiform  antennjp,  and  in  the 
arrangement  proposed  by  me  (Proc.  Am.  Philos.  Soc.  1873,  p.  95) 
should  be  placed  immediately  after  trichrus  (convolvuli),  from  which 
it  differs  in  its  narrow  thorax  and  pale  antennae  and  legs.  In  the 
last  two  particulars  it  is  the  only  one  so  formed  in  the  group. 

One  specimen  from  Arizona,  probably  Fort  Whipple,  given  me 
by  Mr.  A.  Merkel. 

E.  lieterodera  n.  sp. — Oblong,  piceous-black,  densely  clothed  with  fulvous 
pubescence,  varying  to  cinereous,  the  thorax  of  male  entirely  naked.  Antennae 
black,  filiform;  head  closely  punctate,  median  line  finely  impressed,  occiput 
slightly  impressed ; thorax  broader  than  long,  rather  wider  in  the  male,  base 
arcuate,  sides  behind  the  middle  slightly  convergent  in  front  and  then  abruptly 
narrowed  to  the  apex,  disc  rather  flat,  the  median  line  distinctly  imjtressed  ; 
elytra  densely  punctulate,  vaguely  bicostate,  the  pubescence  a little  denser  along 
the  suture;  body  beneath  hlack,  densely  punctulate,  vestiture  similar  to  the 
tipper  surface  ; legs  black,  less  densely  pubescent.  Length  7 — 9.5  mm. ; .28 — .38 
inch. 

Male. — Thorax  smooth,  glabrous,  suhopaque ; anterior  tibiae  with  two  slender 
terminal  spurs. 

FletrirtZe. —Thorax  densely  puhescent,  the  pubescence  much  shorter  than  on  the 
elytra,  along  the  basal  margin  on  each  side  are  four  puuctiform  glabrous  fovete, 
which  are,  however,  very  indistinct  in  the  smaller  specimens. 

In  facies  this  species  resembles  ferruginea  and  sericans,  although 
with  a broader  tliorax  than  either.  It  is  the  only  species  in  the 
group  with  filiform  antenme  in  which  the  thorax  is  decidedly  broader

than  long.  The  most  striking  character  it  possesses  is  in  the  great 
(lissiinihirity  of  the  vestiture  of  the  thorax  in  the  two  sexes. 

Occurs  in  northern  Florida.  Specimens  were  given  me  by  Dr. 
Hamilton  and  Mr.  Henshaw. 

TK<j|{OI>EKA  Lee. 

T.  erosa  Lee. 

The  usual  form  of  this  species  as  found  at  San  Diego  and  vicinity, 
has  the  reticulations  of  the  elytra  very  coarse.  The  color  is  })ale 
orange-yellow,  always  with  the  tip  {)iceous  for  a short  distance.  The 
specimens  seem  about  equally  divided  between  those  with  a piceous 
band  across  the  middle  and  those  without  it. 

There  occurs  in  Owen’s  Valley,  where  I collected  it  rather  abun- 
dantlv,  a form  which  seems  almost  entitled  to  rank  as  a distinct 
species,  although  I consider  it  merely  a race. 

T.  erosa,  race  hitecincta. 

Elytra  with  reticulations  much  closer  than  in  the  typical  form, 
piceous  space  at  apex  better  indicated,  at  middle  a rather  wide,  ex- 
actly transverse  i)iceous  fascia,  the  edges  undulating. 

This  form  seems  a little  more  robust,  and  the  texture  of  the  elytra 
firmer  and  less  coriaceous.

|».  AkliHi*»«tiaiia  n.  sp. — Elongate,  black,  surface  shining,  the  front,  a tri- 
angular space  at  apex  of  thorax,  the  base  and  entire  limb  of  the  elytra  narrowly 
red  ; antennte  black  ; head  sparsely  punctate,  a vague  lontritudinal  impression  of 
the  front;  thorax  narrow,  sides  parallel  near  base,  narrowed  at  apical  third,  a 
vague  depression  at  middle  of  base,  surface  shining,  sparsely  punctate;  elytra 
vaguely  bicostate,  the  surface  nearly  smooth,  the  punctures  minute  and  very 
indistinct;  body  beneath  black,  shining,  very  sparsely  punctate;  legs  black. 
Length  15 — 22  mm.;  .60 — .80  inch.  PI.  1,  fig.  9. 

IMe.— Third  joint  of  antennfe  broader  at  base  than  apex,  forming  a rounded 
angle;  terminal  joint  of  maxillary  palpus  placed  transversely,  elongate  oval, 
narrower  at  apex,  under  side  concave,  with  a sensitive  surface  covering  half  the 
area;  last  ventral  segment  feebly  emarginate. 

Eema?e.— Third  joint  of  antenn?e  narrower  at  base  tban  at  apex  ; last  joint  of 
maxillary  palpus  flattened  cylindrical,  slightly  curved  ; last  ventral  segment 
with  a small  but  acute  incisure. 

This  species  is  related  to  dnbiiabilis  (yittigera  ||  Lee.),  but  differs 
notably  in  the  smoother  and  more  shining  stirftice,  the  costte  of  the 
elytra  are  less  distinct  and  finely,  the  color  of  the  thorax  and  legs  is 
different.

BUPRESTID.E. 

Pcecilonota  debilis  Lee.  An  examination  of  the  type  of  this  insect 
shows  it  to  be  merely  a female,  rather  poorly  developed  of  F.  cyanipes. 
In  the  female  of  the  latter  when  of  full  development  there  is  a feeble 
emargination  of  the  last  ventral  segment.  In  the  debilis  the  segment 
is  nearly  entire. 

DYSTAXIA  Lee. 

The  males  of  D.  Murrayi  Lee.,  the  only  species  known,  have  the 
last  ventral  deeply  and  acutely  triangularly  emarginate.  The  an- 
teniue  are  slender  and  extend  to  a point  opposite  the  first  ventral 
suture,  the  female  has  the  last  ventral  segment  broadly  rounded 
and  entire,  the  antenme  shorter,  not  i-eaching  beyond  the  end  of  the 
metasternum. 

In  mature  specimens  the  body  above  is  of  an  entirely  uniform 
malachite  green,  with  but  feeble  trace  of  pubescence. 

Before  attaining  maturity  the  specimens  are  dark  bronze,  with  a 
coppery  tinge,  and  the  gray  pubescence  is  more  consi)icuous.  On  a 
specimen  of  this  kind  is  founded  D.  Lecontei  Thoms. 

SCHIZOPITS  Lee. 

In  the  typical  species  of  this  genus,  S.  Icefus  Lee.,  the  sexes  differ 
in  a more  striking  manner.  In  the  male  the  under  side  of  the  body, 
head  and  thorax,  all  the  femora  and  the  first  two  joints  of  the  an- 
tennie  are  bluish  submetallic.  The  elytra  are  orange-red,  with  a 
narrow  sutural  edge  blue.  Probably  when  quite  recent  the  elytra 
are  brighter  red.  The  tibise,  tarsi  and  anteniUB,  are  I'ufo-testaceous. 


46 


GEO.  H.  HORN,  M.  D. 


The  last  ventral  segment  is  broadly  triangularly  eniarginate.  The 
antennje  do  not  extend  much  beyond  the  hind  angles  of  the  thorax, 
and  are  similar  in  the  sexes. 

The  female  is  entirely  of  a uniform  blue  above  and  beneath,  some- 
times quite  green,  the  last  ventral  entire. 

For  the  opportunity  of  recording  the  sexual  differences  I am  in- 
debted to  the  National  Museum  at  Washington,  where  numerous 
specimens  were  received  from  San  Diego,  Cal. 

tS.  Sallei  Horn  was  described  from  a female  with  scarcely  any 
trace  of  metallic  siuTace  color.  The  elytra  are  similar  in  color  to 
Mas  % , except  that  there  is  a darker  oblique  vitta  extending  from 
the  humeral  umbone  nearly  to  the  sutural  angle.  The  head  and 
thorax  are  darker  in  color. 

The  oblique  impression  of  the  thorax,  on  which  I laid  some  stress, 
seems  not  to  have  great  value,  as  it  seems  to  be  a variable  quantity 
in  ketm.  The  claws  of  Sallei  are,  however,  much  less  distinctly 
cleft,  and  seem  rather  to  be  provided  with  a small  tooth  at  middle 
after  the  style  of  some  Lachnostern^e. 

This  species  was  collected  at  Mariposa,  Cal.,  by  Mr.  Alphonse 
Thevenet. 

Mr.  F.  Blanchard  is  quite  correct  in  recording  the  presence  of  the 
“ ante-coxal  piece”  of  the  metasternum  in  both  Schizopus  and  Dys- 
taxia.  The  presence  of  this  piece  seems  to  be  quite  characteristic  of 
the  Buprestidse.  In  the  genus  Lissomus,  of  the  Throscidse,  there  is 
no  trace  of  this  piece,  so  that  by  the  fortunate  discovery  by  Mr. 
Blanchard  we  have  a more  ready  method  of  separating  the  latter 
family  from  the  Buprestidte  than  previously  existed,  Lissomus  having 
always  been  an  annoying  element. 

While  the  presence  of  the  “ ante-coxal  piece”  and  its  modification, 
or  entire  absence,  plays  an  important  part  in  the  Adephagous  series, 
it  would  hardly  have  been  suspected  to  have  similar  utility  in  a series 
so  remotely  separated  as  the  Serricornia. 

ACTENODES  Lac. 

A.  ineiKlax  n.  sp. — Form  of  calcarata,  but  somewhat  more  convex,  color 
dark  greenish  bronze  varying  to  cupreous,  feebly  shining;  antennae  short,  ob- 
tusely serrate ; front  rather  flat,  coarsely  and  closely  punctate,  not  longitudinally 
impressed,  surface  rather  uneven  in  the  female;  thorax  more  than  twice  as  wide 
as  long,  sides  parallel,  with  a slight  siuuation,  obliquely  narrowed  at  anterior 
third,  disc  regularly  convex,  moderately  coarsely  and  closely  punctate,  with  a

tendency  to  form  transverse  strigae ; elytra  with  rarely  a trace  of  a costa  near 
the  suture,  the  surface  scabrous,  with  a tendency  to  form  transverse  strigae  to  a 
slight  extent,  the  oblique  portion  of  the  margin  serrate;  body  beneath  more 
shining  than  above,  punctate  and  transversely  strigose.  prosternum  more  coarsely 
punctate;  anterior  femora  toothed  at  outer  third.  Length  12 — 17  mm. ; .48 — .68 
inch. 

In  both  sexes  the  last  ventral  is  truncate,  squarely  in  the  9 > 
slightly  eniarginate  S . The  anterior  tibite  are  serrate  in  the  male 
very  distinctly,  but  in  the  female  this  is  but  faintly  indicated. 

This  insect  has  been  a long  time  in  my  cabinet,  but  I refrained 
from  naming  it,  hoj)ing  that  it  was  a known  Mexican  form,  or  that 
it  would  be  described  in  the  “ Biologia.”  This  not  proving  the  case, 
and  as  specimens  are  occasionally  being  sent  me  I have  thought  it 
well  that  it  should  be  described. 

Known  to  me  from  Texas  to  Fort  Yuma.  A specimen  before  me 
is  labeled  Illinois,  but  the  locality  is  open  to  doubt. 


Bibliographical  Reviews. 


In  a recently  published  part  of  the  “ Biologia  Centrali-Americana 
(vol.  iii,  pt.  1),”  in  reviewing  the  Throscidje,  it  was  observed  that 
Throscus,  as  then  constituted,  was  clearly  divisible  into  two  genera ; 

Throscus  includes  those  in  which  the  metasternum  is  simply  ob- 
liquely impressed,  while 

Aulonothroscus  will  receive  those  with  a rather  deep  and  well- 
defined  groove.  To  this  division  belong  validus,  punctatus,  invisus, 
condridor,  convergens  and  pugnax,  the  remaining  species  will  continue 
as  Throscus,  all  the  European  species  belonging  here,  and  must  be 
accepted  as  the  typical  forms. 

In  the  same  essay,  a few  pages  after,  it  will  be  observed  that  the 
name  Tharops  has  been  superceded  by  Isorhipis,  the  former  name 
having  been  previously  used. 

As  an  illustration  of  the  rather  restricted  distribution  of  the  Euc- 
nemidae  generally,  it  will  be  observed  that  but  few  species  occur 
south  of  our  boundary  which  are  found  within  it,  these  are  Nematodes 
atropos,  Mirn'orhagus  humeralis  and  Anelastes  Druryi,  the  first  being 
somewhat  doubtful,  while  the  last  is  represented  in  both  its  races  the 
shining  {Latreillei)  and  opaque  (Druryi)  as  far  south  as  Guatemala.

In  the  Mexican  fauna  the  species  of  the  family  Throscidje  show 
nothing  in  common.  In  onr  fauna  Throscus  sens.  lat.  is  represented 
hy  thirteen  species,  and  in  ^Mexico  by  five,  while  Drapetes  contains 
twenty-six  in  ^Mexico  and  hut  four  with  us,  in  addition  to  which 
Lissomus  has  twelve  Mexican  species,  and  is  totally  unknown  in  our 
fauna.  Pactopus  makes  a closer  approach  to  the  Eucnemidse  without 
having  any  parallel  in  Mexico.

Desoriptioii!4  of  new  species  of  North  Annericaii  Bees. 

BY  CHARLES  ROBERTSON. 

ANDRENA. 

In  the  study  of  the  mutual  relations  of  flowers  and  insects  I have 
found  many  insects  which  I could  neither  determine  myself  nor  get 
determined  by  others.  Conspicuous  among  these  are  the  species  of 
Andrena.  In  order,  therefore,  to  get  names  for  use  in  my  biological 
work,  I have  undertaken  to  describe  as  best  I could  the  species  which 
occur  in  my  neighborhood.  Some  of  them  may  have  been  described 
before,  by  Smith,  in  British  Museum  Cat.  Hym.  and  in  New  Spec. 
Hym.  Brit.  Mus.  After  careful  study  I have  been  unable  to  deter- 
mine more  than  two  of  Smith’s  species.  The  fact  that  a specimen 
agrees  in  every  detail  with  Smith’s  description  would  not,  to  my 
mind,  establish  the  probability  of  its  being  the  same  as  its  type.  His 
descriptions  are  limited  almost  entirely  to  the  colors  of  the  pubes- 
cence, which  is  variable  and  liable  to  fade.  Thus,  of  the  twenty-four 
female  specimens  of  A.  Cressonii,  only  three  show  the  normal  color 
of  the  pubescence.  The  color  of  the  surface  is  also  very  variable. 
The  abdomen  sometimes  varies  from  entirely  red  to  entirelv  black. 
Sets  of  specimens  in  which  the  legs  are  commonly  black,  with  the 
apical  joints  ferruginous,  often  show  individuals  having  the  tarsi,  the 
middle  tibiae  at  tips,  and  the  hind  tibiae  entirely  ferruginous. 

In  all,  or  most  of  the  species,  the  ground  surface  is  minutely  rough- 
ened. Unless  there  is  a distinct  punctuation  in  addition  to  this,  I 
call  the  surface  impunctate.  One  trouble  with  Smith’s  descriptions 
is  that  one  cannot  always  be  certain  whether  he  refers  to  this  minutely 
roughened  surface  or  to  a distinct  punctuation. 

Of  the  twenty-six  species  of  Andrena  mentioned  in  this  paper,  I 
have  both  sexes,  except  in  five  cases.  I have  taken  the  sexes  of 
eleven  species  in  copula.  These  bees  can  best  be  collected  by  watch- 
ing flowers  of  willows  in  Spring  and  of  Composite  in  fall.  The 
females  should  be  identified  first  and  the  males  referred  to  them. 

I submit  a synopsis  of  all  the  species  which  occur  in  my  neighbor- 
hood (Carlinville,  111.)  with  notes  on  their  time  of  flight  and  the 
flowers  which  they  visit,  as  well  as  descriptions  of  the  new  species. 

Besides  those  given  below  I have  ten  sets  of  specimens  which  indi- 
cate the  presence  of  several  additional  species.

CATAI.OGIIE  OF  THE  HE^CRIBED  SPEC’IES  OF 
SOUTH  AMERICAN  ASIEID.E. 

BY  S.  W.  WILLISTON. 

'File  following  preliminary  catalogue  of  the  described  species  of 
South  American  Asilidse  is  offered  in  the  hope  that  it  may  lighten 
the  labors  of  students  of  the  South  American  Dipterous  fauna.  It 
was  originally  prejiared,  two  years  ago,  as  a preliminary  to  the  study 
of  a Brazilian  collection  in  this  family,  and  has  been  recently  sub- 
jected to  a careful  revision.  It  will  be  strange  if,  among  so  many 
references,  some  errors,  both  of  omission  and  commission,  are  not 
found.  I can  only  say  in  extenuation  of  such,  that  the  entire  paper 
has  been  repeatedly  written  and  the  references  as  often  compared. 
Schiller’s  list  of  specific  names  of  the  Asilidie  of  the  world,  which 
seems  to  be  very  complete  to  1860,  has  been  of  material  service,  as 
also  Lynch’s  partial  catalogue.  The  distribution  of  the  genera  is 
chiefly  that  of  Schiner ; some  few  changes  have  been  made  in  ac- 
cordance with  Lynch’s,  Osteu  Sackeu’s,  or  my  own  views.  A very 
few  of  the  less  important  works  have  been  inaccessible  to  me,  and  it 
is  in  them  that  additional  references  may  be  found.  The  references 
thus  taken  at  second  hand  will  be  found  preceded  by  an  asterisk. 
No  references  later  than  1889  are  included.

A GKIVERIC'  SYl^OPSIS  OF  THE  €OC'<  IIEE. 

BY  WILLIAM  H.  ASHMEAD. 

Family  X. — COCCIDtE. 

Soft  liodied  insects  of  the  smallest  size.  The  females  and  the 
young  larvse,  of  both  sexes,  are  degraded,  mite-like  in  appearance, 
oval  or  elli))tical  in  shape,  with  the  head  not  distinctly  sej)arable 
from  the  thoracic  segment,  apjiearing  merely  as  a segment  with 
rounded  eyes  placed  toward  the  sides,  the  short,  subsetaceous,  5-  to 
11-jointed  antenme  being  situated  just  a little  in  advance.  Ocelli 
usually  present.  Beak  usually  1 -jointed,  and  seldom  with  more  than 
2 joints,  enclosing  4 long,  delicate  setae.  Legs  usually  short ; tarsi 
1 -jointed  and  usually  with  digitules.  The  adult  males,  in  this  anom- 
alous family,  present  a very  different  appearance  from  the  females 
and  young  larvie ; they  are  elongate  ovate,  with  a well  developed 
thorax,  a large  scutellum,  a distinct,  small,  rounded  or  quadrately 
shaped  head,  with  the  eyes  quite  large,  either  smooth  or  facetted, 
while  the  antenme  are  long,  filiform,  and  composed  of  from  9 to  11 
joints,  usually  ])ubescent,  but  occasionally  with  whorls  of  hairs. 
The  beak,  in  this  sex,  is  wanting ; where  it  should  be,  are  two  large, 
shining  ocelli.  The  legs  are  of  moderate  length,  never  greatly  thick- 
ened ; the  tibiae  sometimes  as  thick,  or  thicker  than  the  femora; 
tarsi  1 -jointed,  stout,  ending  in  a single  claw,  and  usually  furnished 
with  knobbed  digitules.  Most  of  the  males  known  in  this  family 
have  two  wings,  the  venation  consisting  of  a single  longitudinal  vein 
with  a simple,  oblique,  discoidal  branch,  the  hind  wings  being  aborted, 
and  in  their  place  is  a pair  of  halters,  as  in  the  Diptera.  Some  few 
males  in  the  genus  Lecaniwn  have  been  discovered  recently  to  be 
entirely  wingless,  and  it  is  quite  probable  that  with  closer  study  wing- 
less males  in  other  genera  will  be  found.  Subapterous  males  are 
not  uncommon.  The  abdomen  in  the  male  is  simple,  or  terminates 
in  two  long  caudal  setse,  a brush  of  filamentous  down,  or  then  armed 
with  a long  stylus,  with  oi‘  without  caudal  setse. 

The  habits  of  this  anomalous  family  are  quite  interesting;  the 
vast  majority  of  the  species  becoming  quiescent  and  stationary  upon 
their  food-plants,  cover  themselves  with  a waxy  or  calcareous  sub- 
stance, which,  together  with  their  castings  or  moults,  affords  a jiro- 
tection  for  their  soft  bodies,  termed  a scale,  shield,  test,  sac  or  en- 
venope.  The  name,  therefore,  popularly  given  to  them — “Scale 
insect” — is  very  appropriate,  although  some  of  them  do  not  become

quiescent  and  form  the  scaly  covering,  but  are  capable  of  moving 
freely  about  on  their  food-j)lant,  entirely  unprotected,  oi-  then  only 
covered  with  a filamentous,  floccnlent  or  pulverulent  substance, 
whilst  a few  species  have  been  discovered  in  Australia  living  in  galls 
or  excrescences,  on  the  leaves  of  the  Eucalyptus  tree.  I also  know 
of  a gall-rnaking  species  in  Florida. 

ihe  family  may  be  divided  conveniently  into  five  subfamilies, 
apparently  natural  groups,  based  upon  the  studies  of  Signoret,  Tar- 
gione,  Low,  Masked,  Comstock,  Atkinson  and  others,  recognizable 
by  the  aid  of  the  following  table ;

BY  JOHN  B.  SMITH. 

Cernia  olivacea  n.  sp. — Ground  color  an  olivaceous  gray,  with  bluish 
green  and  white  powderings.  Head  and  thorax  irregularly  mottled,  with  a con- 
siderable admixture  of  black  scales.  Basal  line  distinct,  black,  followed  by  a 
white  line.  T.  a.  line  black,  preceded  by  a white  line  with  long  outward  teeth 
on  the  subcostal  and  median  veins,  an  incurve  in  submedian  interspace,  with 
another  long  tooth  on  the  internal  vein.  T.  p.  line  is  irregular,  rivulous,  in  gen- 
eral course  a rather  even  outcurve.  S.  t.  line  indefinite,  the  space  between  t.  p. 
line  and  outer  margin  being  irregularly  blotchy;  an  even  dusky  terminal  line. 
Fringes  pale,  cut  with  fuscous.  Claviform  concolorous,  defined  by  a black  semi- 
circle below  the  orbicular  and  a vague  black  pow’dering  from  the  horns  of  this 
to  the  t.  a.  line.  Orbicular  moderate  in  size,  round,  concolorous,  defined  by  a 
greenish  annulus  edged  with  black  scales,  and  with  a whitish  central  dot.  Reni- 
form  large,  somewhat  constricted  medially  very  incompletely  defined  in  black, 
with  greenish  powderings  which  extend  to  the  costal  margin.  Secondaries 
smoky  fuscous,  somewhat  paler  basally,  with  a small  discal  lunule  and  a faint 
extra  median  line.  Beneath,  primaries  blackish  powdery,  paler  along  inner 
margin  ; secondaries  whitish,  with  a dark  discal  lunule  and  a powdery  outer 
margin.  Expands  1.20 — 1.28  inches;  30 — 32  mm. 

Hab. — Colorado  ; Sierra  Nevada,  Cal. 

I have  seen  three  specimens  of  this  very  distinct  species,  all  males. 
Two  are  from  Mr.  Edwards,  one  of  them  rather  rubbed,  the  third  is 
from  ]\Ir.  Bruce’s  collecting,  sent  several  years  ago  to  Mr.  Cramer, 
now  in  collection  United  States  National  Museum.  In  this  specimen 
the  green  has  faded  to  the  sordid  yellow  so  commonly  assumed  by 
this  color  in  the  noctuids,  but  in  maculation  there  is  absolutely  no 
difference.  It  is  much  larger  than  the  eastern  C-  cora,  and  the  de- 
tails of  maculation  differ  quite  widely  while  the  pattern  remains 
similar.  It  is  fully  congeneric  with  our  eastern  species,  without 
meaning  to  assert  its  distinctness  from  Bryophila.

Pacliiiobia  ciiieraseens  ii.  sp. — Pale  luteous  gray ; sometimes  with  a 
slight  reddish  suffusion,  sometimes  quite  well  powdered  with  black  scales.  Head 
and  thorax  concolorous.  Basal  line  distinct,  rigid,  single.  T.  a.  line  single, 
blackish,  oblique,  outwardly  angulated  below  the  costa,  nearly  straight  through 
the  cell,  outcurved  in  the  submedian  and  marginal  interspace.  T.  p.  line  single, 
blackish,  distinct,  only  a little  outcurved  over  the  cell,  finely  crenulated.  S.  t. 
line  concolorous,  marked  by  a defined  blackish  preceding  shade,  which  fades  into 
the  ground  color  before  the  t.  p.  line.  A broken  brown  terminal  line,  followed 
by  a faint  yellowish  line  at  base  of  fringes.  Claviform  wanting;  orbicular  round

distinct  yellowish  line  at  base  of  fringes.  Beneatli  gray,  primaries  vaiying  to 
smoky  brown,  secondaries  ))owdery.  A common,  varialily  complete  outer  line 
and  a distinct  large  discal  spot  sometimes  obscured  on  the  primaries.  E.xpands 
1.20 — 1.40  inch. ; 30 — 3.5  mm. 

Hub. — Alameda  County,  Cal.,  September  and  October. 

Four  male  specimens  are  in  the  museum  collection  (through  C.  V. 
Uiley)  hearing  the  red  number  339. 

This  species  is  aberrant  in  color  for  the  genus,  hut  in  wing  form 
and  in  pattern  of  ornamentation  it  is  allied  to  carnea.  Its  luteous 
gray  color,  single  median  lines,  and  contrasting  black  ordinary  spots, 
render  it  easily  recognizable.  The  antennae  are  “ brush  like,’’  l.e., 
the  joints  slightly  produced  laterally  and  furnished  with  bristly 
tufts.  The  thoracic  vestiture  forms  an  indefinite  dorsal  crest.  The 
male  genitalia  have  the  harpes  ohliijue  at  tip,  forming  a little  pro- 
jecting tooth  interiorly.  The  clasper  is  a single,  stout,  straight, 
pointed,  corneous  spur. 

" A / ^ 

l*acliiiobisi  elevata  u.  sp. — Ground  color  of  the  reddish  gray  usual  in 
this  genus.  Head  and  thorax  immaculate.  Primaries  with  the  ordinary  lines 
single.  Basal  line  interrupted,  rather  indefinite.  T.  a.  line  incomplete,  ap- 
jiarently  upright  and  rather  even  to  internal  vein,  below  which  it  makes  an 
outcurve.  T.  p.  line  complete,  even,  exserted  over  the  cell,  and  somewhat  ir- 
regularly ohliipie  below  to  margin.  A paler,  more  grayish  shade  through  the 
s.  t.  space,  in  which  a series  of  interspaceal  brown  dashes  indicate  the  s.  t.  line. 
.\u  interrupted  terminal  line.  Claviform  a yellowish  streak  from  base  to  near 
middle  of  median  space,  outlined  beyond  t.  a.  line  by  a narrow  black  line.  Or- 
bicular elongate,  the  angles  drawn  out  toward  base  and  apex.  Eeiiiform  small, 
lunate.  Both  spots  are  a somewhat  paler  gray  and  outlined  by  black  scales. 
Secondaries  whitish,  smoky  toward  apices.  Beneath  whitish,  powdery,  with  a 
diffuse  common  outer  line  and  a moderate  discal  spot  on  all  wings.  Expands 
1.40  inches;  .35  mm. 

Hab. — Colorado  (Bruce). 

A single  good  male  from  Mr.  Neumoegen’s  collection.  The  speci- 
men has  the  antenine  serrate  and  bristled,  and  is  therefore  allied  to 
C'lrnea,  than  which  it  has  .somewhat  more  pointed  wings  and  entirely 
diflerent  markings.  The  cell  is  not  black-filled  around  the  ordinary 
spots,  and  the  character  of  the  transverse  lines  is  entirely  different. 
The  genitalia  consist  of  a broad  harpe  with  obtusely  rounded  tip, 
inwardly  fringed  with  spinules.  From  the  centre  of  this  arises  a 
broad,  excavated,  corneous  process,  with  an  irregular  outline,  form- 
ing the  clasper.

Ciii'iiesMleM  f'lii^iiiiaciila  n.  sp. — Head  and  thorax  mouse-gray,  collar  with 
a blackish  central  line.  Primaries  dull  red-brown,  subcostal  and  median  vein 
white  i)owdered.  Basal  line  geminate,  well  defined,  included  space  with  white

on  cell,  then  evenly  oblique  outwardly  to  hind  margin.  Below  the  median  vein 
the  defining  lines  are  well  written,  the  included  space  concolorous.  T.  p.  line 
even,  outcurved  over  cell,  thence  parallel  with  outer  margin.  The  inner  de- 
fining line  is  a series  of  blackish  lunules,  the  outer  a vague,  diffn.se  line,  the  in- 
cluded space  very  slightly  paler  than  ground  color.  S.  t.  line  marked  only  by 
the  slight  difference  in  shade  between  s.  t.  and  terminal  spaces;  an  interrupted, 
sublimate  terminal  black  line,  followed  by  a narrow  yellow  line  at  base  of  fringes. 
Apical  spot  powdered  by  a few  white  scales;  a black  basal  dash  below  median 
vein,  joining  to  the  moderate,  black  margined  claviform.  A black  filling  to  the 
cell  before  orbicular,  and  between  the  ordinary  spots.  The  latter  are  fused,  the 
orbicular  oblong,  oblique,  merging  interiorly  into  the  reniform,  which  is  some- 
what extended  outwardly  from  its  lower  angle.  The  combined  spot  narrowly

wise concolorous  spots.  Secondaries  even,  smoky  fuscous,  with  paler,  interlined 
fringes.  Beneath  smoky  fuscous,  powdery,  with  an  incomplete  outer  line  and 
somewhat  indefinite  discal  lunule.  Expands  1.28  inches;  32  mm. 

Hab. — California. 

A single  male  specimen  iti  good  condition.  The  characters  of  the 
tessellata  group  are  well  marked,  and  the  sjtecies  is  intertuediate 
between  divergens  and  redhnicula,  differing  amply  from  both  in  the 
fused  ordinary  spots.  The  white  marked  veins  are  like  divergens, 
while  the  s.  t.  line  is  like  redimieula.  The  male  characters  agree 
with  those  of  the  allied  species,  and  figure  64  of  my  Revision  of 
Agrotis  will  answer  for  this  species  equally  well. 

I*erig<*a  piilveriileiita  n.  sp.— fTi-ound  color  a vague,  powdery  reddish 
gray,  varying  in  tint  according  to  the  relative  ju-edominence  of  red,  white,  or 
blackish  scales.  All  the  noiinal  maculation  present,  hut  obscured  by  the  pow- 
dery ba.se.  Basal  line  geminate,  concolorous,  defining  lines  fuscous  or  blackish, 
twice  augulated.  T.  a.  line  somewhat  paler,  with  fuscous  or  black  defining 
lines,  not  always  complete  and  sometimes  vague;  outwardly  oblique,  somewhat 
curved,  inwardly  angulate  on  the  median  and  submedian  veins.  T.  p.  line  ob- 
soletely  geminate,  the  inner  line  lunulate,  the  outer  vague  and  even,  sometimes 
wanting,  its  course  evenly  bisinuate  without  the  usual  long  outcurve  from  the 
costa  over  reniform.  S.  t.  space  palei-  than  median  and  usually  also  than  terminal 
space;  s.  t.  line  pale,  diffuse,  sinuate,  marked  by  the  difierence  in  shade  between 
s.  t.  and  terminal  space,  and  also  djy  a more  or  less  obvious  preceding  shade, 
h'ringes  interlined  with  fuscou.s,  feebly  scalloped:  median  space,  as  a whole, 
somewhat  darker  than  the  rest  of  the  wing;  a dusky  or  blackish  median  shade 
which  in  the  submedian  interspace  sometimes  forms  a complete  connection  be- 
tween the  median  lines.  Claviform  small,  though  quite  wide,  concolorous,  in- 
completely outlined  in  black.  Orbicular  round  or  oval,  oblique,  pale  ringed  with 
dusky  centre.  Reniform  uiiright,  quite  large,  somewhat  constricted  centrally, 
pale  ringed  with  concolorous  or  paler  center.  A dusky  costal  iritch  in  the  s.  t.

broad  black  outer  margin,  a narrow  preceding  dusky  line  and  a dusky  discal 
lunule.  Fringes  pale,  interlined  with  fuscous.  Beneath  powdery,  primaries 
darker,  both  wings  with  a discal  spot,  narrow  outer  line  and  broad  dark  outer 
margin,  all  variable  in  distinctness.  Expands  1.00--1.08  inches;  25  — 27  mm. 

Hub. — Colorado  (Bruce);  Las  Vegas,  N.  Mex.  (Meeske);  New 
Mexico  (Show);  Arizona  (Edwards). 

This  little  species  has  long  puzzled  me,  and  I refer  it  to  Perirjea, 
rather  because  it  is  congeneric  with  P.  pei'plexa  Grt.,  than  because 
it  strictly  belongs  here. 

Four  of  the  specimens  collected  by  Mr.  Bruce  are  in  the  collection 
of  the  United  States  National  IMuseum,  two  of  them  labeled  simply 
“ Colorado,”  the  others  labeled  “ Foot-hills.”  There  is  little  or  no 
variation,  and  the  species  once  generically  [ilaced,  is  easily  recogniz- 
able. 

l*oliit  pul VPrnloiita  n.  sp  — Ground  color  a powdery  ashen  gray,  the 
markings  indefinite,  vague.  Basal  Hue  black,  interrupted,  apparently  single. 
T.  a.  line  single,  black,  rather  diffuse,  outwardly  oblique  and  somewhat  outcurved 
between  the  veins.  T.  p.  line  crenulate.  outcurved  over  the  cell  and  parallel 
with  outer  margin  below  that  point,  blackish,  interrupted,  almost  lunulated,  and 
nearly  obsolete  toward  costa.  This  line  is  quite  well  removed  toward  margin, 
widening  the  median  space  and  narrowing  the  space  beyond  to  the  outer  margin. 
A series  of  somewhat  diffuse  iuterspaceal  black  marks  indicates  the  s.  t.  line:  a 
series  of  small  terminal  lunules.  Fringes  gray.  Claviform  vaguely  indicated 
by  a blackish  shade.  Ordinary  spots  vague,  indefinite,  concolorous,  incompletely 
outlined,  apparently  of  the  usual  shape  and  proportionate  in  size.  An  oblique, 
diffuse  blackish  shade  from  costa,  outwardly  over  the  reniform  and  darkening 
it  interiorly;  continued  as  a vague  fuscous  shading  through  the  median  space. 
Secondaries  dirty  white,  powdery,  veins  soiled,  a dusky  lunate  marginal  line  and 
discal  spot  and  extra  discal  line  of  under  side  showing  through.  Beneath 
whitish,  powdery,  with  a common  extra  discal  line  and  a discal  spot  on  all  wings. 
The  hind  angle  of  primaries  is  somewhat  retracted  ; thorax  with  a small,  divided 
anterior  crest,  and  a more  distinct  posterior  tuft ; abdominal  tufts  small.  Ex- 
pands 1.88 — 2.08  inches;  47 — 52  mm. 

Hab. — Colorado. 

Two  male  specimens  with  serrate  and  tufted  (brush-like)  tintenna. 
This  species,  though  referred  to  Polia,  jirobably  cannot  remain  in 
this  genus.  It  is  referred  there  because  it  is  quite  close  to  and  per- 
fectly congeneric  with  Polia  contacta  Wlk.,  which  it  resembles  both 
in  size,  color  and  general  habitus,  differing  abundantly  in  many  re- 
spects. The  species  liears  a very  decided  resemblance  to  Mamestra 
discalis,  and  a specimen  in  the  Museum  collection  (from  the  Meske 
collection)  bears  Mr.  Grote’s  label,  Mamestra  discalis.  The  specimen

was  collected  by  Snow,  and  I feel  assured  there  are  others  of  this 
species  so  misnamed.  The  other  specimen  was  sent  me  by  Mr. 
Bruce. 

The  genus  Folia  contains  quite  diverse  material,  and  the  species 
will  probably  be  distributed  among  other  genera,  some  mayhap  to 
Hadena.  Indeed,  Mr.  Grote  has  described  the  same  species  as  a 
Hadenu  (diversilineata),  and  again  as  a Folia  (illepida). 

€AL,OPHASIA  Steph. 

Head  not  retracted.  Thorax  with  fine,  smooth  vestiture.  Abdo- 
men without  dorsal  tufts.  Antenme  of  male  with  short,  rather  dense 
cilire,  at  base  with  a feeble  tuft,  thorax  posteriorly  with  a truncate 
tuft.  Primaries  short,  widening  outwardly,  more  strongly  rounded 
at  internal  angle,  outer  margin  and  fringes  entire.  The  above  char- 
acterization is  from  von  Heinemann  (Schmett.  Deutsch.  391),  and 
with  it  agrees  fairly  well  a species  which  does  not  seem  to  fall  in 
naturally  with  any  American  genus  known  to  me.  In  wing  form 
the  species  agrees  well  with  opalina ; in  type  of  maculation  it  is  more 
like  platyptera,  the  latter  being  wider  Avinged  than  its  congener. 

PalopliHSia  strigata  n.  sp. — Head,  thorax  and  primaries  ash-gray.  Head 
marked  with  fuscous,  collar  paler  at  base.  Thorax  with  an  admixture  of  fus- 
cous scales.  Primaries  with  a dusky  shade  through  the  cell  and  terminally,  the 
transverse  lines  obsolete;  the  veins  are  ail  black  marked,  and  the  wing  has 
therefore,  a strigate  appearance.  Claviform  long,  extending  from  the  base  to 
beyond  the  middle  of  the  wing,  with  narrow  black  defining  lines,  filled  with  a 
reddish  sulfusion.  A faint  reddish  tinge  beyond  the  reniform,  which  is  white 
ringed,  narrow,  upright,  with  an  inferior  spur  projecting  inwardly  toward  the 
orbicular.  The  latter  is  narrow,  clavate,  oblique,  white  ringed.  On  veins  3 and 
4 the  dusky  terminal  shade  is  cut  by  a white  shade  accompan.ying  the  veins-  a 
row  of  small,  dusky  terminal  lunules.  Fringes  cut  with  fuscous,  and  rather  lout^ 
Secondaries  whitish  basally,  soiled  fuscous  outwardly,  the  veins  dusky.  Beueatl: 
whitish,  pow’dery..  Expands  1.20  inches  ; 30  mm. 

Flab. — Colorado  (Bruce). 

Two  female  specimens  are  before  me,  neither  of  them  entirely 
perfect,  but  yet  in  excellent  condition.  The  species  has  the  appear- 
ance of  Oncocnemis  without  its  structure.  One  of  the  sjiecimens  is 
in  the  United  States  National  Museum.

ter  mostly  flattened  scales,  collar  not  crested.  The  palpi  with  coarse 
vestiture  and  small  terminal  joint.  Antenme  at  base  with  a tiift  of 
hair,  serrated  in  the  males,  with  bristle  tuftings.  The  thorax  quad- 
rate, laterally  produced  at  the  angles,  with  smooth  anterior  and  pos- 
terior tufts,  abdomen  untufted.  Primaries  short,  not  greatly  widen- 
ing, apices  not  acute,  margin  evenly  rounded,  fringes  scalloped. 

This  is  von  Heinemann’s  definition,  and  it  agrees  well  with  the 
European  species,  but  not  at  all  with  the  American  species  referred 
to  the  genus.  Dryobata  opina  Mr.  Grote  now  refers  to  Valeri)i,  while 
stiymaia  is  utterly  unlike  the  European  species.  The  wing  form  is 
alisolutely  different,  the  fringes  are  only  feebly  sinuate  and  not  scal- 
loped, and  the  abdomen  is  prominently  tufted  ; but  I know  at 
jiresent  no  other  genus  to  which  stigmata  could  be  better  referred,  and 
as  I believe  it  has  congeners  in  other  genera  I will  simply  call  atten- 
tion to  the  fact,  here,  preliminary  to  the  description  of  three  species 
agreeing  better  with  the  description  of  the  genus,  but  very  unlike 
stigmata  in  every  respect,  and,  though  themselves  congeneric,  and 
with  the  same  habitus,  differing  quite  strongly  in  antennal  structure. 

The  species  are  ash-gray,  with  a reddish  or  brownish  suffusion, 
])owdery,  all  the  maculation  well  marked.  The  ordinary  spots  are 
well  sized,  and  as  a whole  the  species  have  a very  decided  resem- 
blance to  Litholomia  napee  in  type  of  maculation,  emphasized  by  the 
more  or  less  prominent,  rigid,  dark,  median  shade  or  line,  which 
forms  the  most  obvious  ornamental  feature.  One  of  the  species 
which  I had  dubbed  Hadena  latifascia,  perhaps  in  one  or  two  collec- 
tions, I find  is  Prof.  French’s  Homohadena  elda.  It  has  nothing, 
whatever,  in  common  with  Homohadena,  and  this  species  is  perhaps 
nearest  of  all  to  tyjiical  form  of  the  genus. 

I>i\yobata  elda  French. 

1887  Can.  Ent.  xix,  5,  Homohndena. 

The  male  autennge  are  di.stiuctly  and  well  pectinated;  in  the  female  the  joints 
are  marked.  A broad  brown  shade  with  blackish  defining  lines  fills  the  space 
between  the  ordinary  spots,  and  below  the  median  vein  its  outer  border  extends 
along  the  t.  p.  line. 

Four  specimens  in  the  National  Museum  collection  (through  C. 
V.  Riley)  are  from  Nevada  County,  Cal.,  Septemher,  collected  by 
Koebele,  and  Mr.  Edwards  has  also  sent  it  to  me  labeled  Sierra 
Nevada,  Cal. 

I>ryobata  rectiTai^icia  u.  sp. — Eather  dark  bluish  ashen.  Collar  with  a 
broad  median  black  line.  Basal  half  line  distinct,  pale,  obsoletely  geminate;  a 
short,  black,  longitudinal  basal  line  extending  to  the  half  line,  the  inclosed  costal

space  paler  and  with  a brick-red  tinge.  T.  a.  line  upright,  or  a little  outwardly 
oblique,  geminate,  outer  defining  line  usually  very  distinct  and  touching  the 
orbicular  in  its  course.  T.  p.  line  geminate,  inner  line  darker,  included  space 
paler;  in  course  it  is  very  even,  widely  outcurved  over  the  reniform,  altogether 
what  might  be  termed  S-shaped,  with  most  of  lower  extension  lopped  ofl’.  The 
s.  t.  si)ace  is  pale,  except  costally,  darkening  to  form  a continuous  dusky  shade 
before  tbe  s.  t.  line,  which  is  pale  and  irregularly  sinuate.  Tliere  is  an  admix- 
ture of  reddish  scales  in  this  preceding  shade  which  is  most  obvious  at  anal 
angle.  A prominent,  rigid  black  line  from  the  costa,  forming  the  inner  margin 
of  reniform  and  continued  thence  to  the  hind  margin  at  t.  p.  line.  Claviform 
small,  indefinite,  marked  only  by  a vague  brick-red  shade.  Reniform  large, 
kidney-shaped,  suffused  with  brick-red  : a black  line  at  base  of  fringes,  which 
have  a dusky  interline.  Secondaries  soiled  white,  veins  and  terminal  line  dusky. 
Beneath  whitish  powdery,  with  a more  or  less  complete  outei'  line  and  discal 
spot.  Expands  1.24 — 1.40  inches;  31 — 3.5  mm. 

Hab. — Sierra  Nevada,  Cal.  (Edwards). 

The  anteimte  of  the  male  have  the  joints  but  feebly  marked  and 
ciliated,  not  at  all  serrate,  much  less  pectinated.  The  transverse 
median  line  corresponds  to  the  outer  defining  line  of  the  median 
shade  in  elda,  but  is  more  prominent.  The  differences  in  details  need 
not  be  pointed  out  where  structural  characters  declare  the  species 
difierent. 

An  incomplete  specimen  is  in  the  United  States  National  Museum  ; 
the  wings  and  antennm  are,  however,  perfect,  and  the  specimen  is 
one  of  my  types. 

Dryobota.  ciirvitascia  n.  sp. — Asheu-gray  or  darker,  with  or  without 
an  admixture  of  hiick-red  scales,  the  black  maculatiou  consisting  generally  of 
elevated  scales,  giving  the  species  a rough  or  “squammose”  appearance.  Collar 
inferiorly  pale,  a vague  reddish  median  line,  surmounted  by  an  equally  vague 
blackish  one.  Primaries,  basal  line  geminate,  blackish,  vague,  reaching  to  the 
short  black  basal  dash,  along  which  a brick-red  shade  is  more  or  less  marked. 
T.  a.  Hue  geminate,  incomplete,  outwardly  oblique  and  slightly  curved  between 
the  veins.  T.  p.  line  vague,  scarcely  definable,  obsoletely  geminate,  evenly  out- 
curved  over  cell,  and  incurved  beneath.  The  s.  t.  space  is  outwardly  a little 
paler,  a partial  series  of  black  or  blackish  lunules,  becoming  more  distinct  toward 
inner  margin  ; an  admixture  of  reddish  in  these  lunules  also  increases  toward 
anal  angle.  Terminal  space  dusky;  a blackish  terminal  line  and  a narrow  pale 
line  at  base  of  fringes.  Claviform  apparently  obsolete.  Orbicular  oblong,  ob- 
lique, concolorous,  with  a narrow  black  margin  and  a very  narrow  white  annulus. 
Reniform  narrow,  quite  long,  lunate,  shot  with  reddish,  defined  by  black  and 
white  scales  rather  than  lines.  A dusky  median  shade,  feebly  Insinuate,  touch- 
ing neither  of  the  spots  and  reaching  margin  between  the  ordinary  lines.  Sec- 
ondaries soiled  white  or  smoky,  with  a blackish  terminal  line.  Beneath  pow- 
dery, pale,  with  a variably  distinct  discal  spot  and  outer  line.  Expands  1.12 — 
1.20  inches  ; 28—30  mm.

The  Placer  County  specimen  in  the  United  States  National  Mu- 
seum is  the  smallest  of  the  three,  and  is  also  most  obscurely  marked. 
It  lacks  the  brick-red  shades  altogether,  the  gray  is  more  sordid  and 
even,  and  the  maculation  is  less  definite  than  in  the  other  specimens. 

The  male  antemue  are  rather  lengthily  serrated,  almost  pectinated, 
differing  from  both  the  j)receding  species  in  this  character  as  well  as 
in  the  median  shade,  which  is  here  not  at  all  prominent,  narrow  and 
sinuate,  not  touching  either  of  the  ordinary  s[)Ots  nor  the  t.  p.  line. 

Apainea  liiiiata  u.  sp. — Ground  color  a powdery  reddish  ocher.  Head 
and  thorax  innuaculate.  Primaries  with  basal  line  apparently  wanting.  T.  a. 
line  narrow,  vvhitish,  evenly  outcurved.  T.  p.  narrow,  whitish,  even,  but  little 
outcurved  over  cell  and  rigidly  oblique  below.  S.  t.  line  marked  by  a j)receding 
costal  shade  and  a series  of  interspaceal  black  dots;  a brown  line  at  base  of 
fringes.  Claviform  and  orbicular  obsolete.  Reniform  a narrow  white  lunule, 
margined  by  black  scales  at  the  end  of  the  cell.  The  veins,  through  the  median 
space,  are  more  or  less  evidently  black  powdered  Secondaries  very  pale  cop- 
pery, somewhat  more  dusky  outwardly.  Beneath  pale,  with  reddish  powderings. 
Expands  l.Ol — 1.12  inches;  26 — 28  mm. 

Hab. — Alameda,  Cal.,  iu  June;  Mt.  Shasta  District,  Cal.  (Ed- 
wards). 

15oth  sexes  are  before  me.  The  species  is  allied  to  parpnripennis 
Grt.,  but  the  ground  color  is  entirely  different,  and  there  is  not  the 
least  chance  of  confusing  the  species.  The  male  antennae  are  later- 
ally tufted  with  short  bristly  hair,  but  not  serrate. 

Orthosia  disUeha  Morr.  has  hairy  eyes,  and  is  an  Ulolonche  Smith. 
Tt  comes  close  to  U.  fasciata  in  type  of  maculation  as  ivell  as  wing 
form  ; but  besides  the  difference  in  color  the  contrasts  are  nowhere  as 
defined,  and  the  reniform  is  not  discolorous,  though  it  is  well  defined 
and  of  the  .same  form. 

The  male  genitalia  agree  perfectly  in  type  with  the  species  which 
I have  already  included  in  this  genus  (pnodesta,  fascuda,  niveignttata) . 

This  seems  to  be  oue  of  the  cases  where  the  sexual  structure  is  of 
generic,  rather  than  specific  importance,  the  agreement  being  close 
in  type  and  in  details,  while  the  ornamental  characters  are  widely 
variant. 

Telesilla  carneola  n.  sp. — Head  and  thorax  a carueous  or  vinous  gray, 
powdery,  apparently  without  distinctive  ornamentation,  but  the  specimen  is 
imperfect  iu  this  respect.  Primaries  with  a fine  vinous  red  ground  color,  more 
or  less  evidently  gray  powdered,  median  space  with  a deep,  blackish  brown 
shading.  Terminal  space  deep  umber-brown.  Basal  line  very  indistinct,  nar- 
row. composed  of  whitish  atoms.  T.  a.  line  narrow,  thread  like,  [lowdery,  gray, 
slightly  outcurved.  T.  }i.  hue  vague,  powdery,  defined  rather  by  the  difference

in  shade  between  the  median  and  subterminal  space,  and  by  short  black  lines  on 
the  veins,  followed  by  minute  white  dots;  a whitish  powdering  through  the  s.  t. 
space,  which  becomes  darker  outwardly,  shading  into  the  deep  brown  terminal 
space.  S.  t.  line  very  indistinct,  broken,  barely  traceable,  its  course  irregular. 
Fringes  dark,  with  a grayish  central  line.  Orbicular  small,  round,  concolorous 
outlined  in  pale  gray.  Eeniform  slightly  constricted  medially,  concoloroms,  out- 
lined by  a narrow  gray  line.  Secondaries  yellow  fuscous  at  base,  becoming 
smoky  outwardly,  a pale  line  at  base  of  fringes.  Beneath  brown,  powdery,  with 
a median  line  and  vague  discal  spot  on  primaries.  Secondaries  pale  basally,  a 
broad  dark  extra  median  line  and  a small  discal  dot.  Expands  1 inch  ; 25  mm.

A single  specimen  from  Mr.  IS'eumoegen’s  collection,  taken  by  Mr. 
Meeske  in  1889. 

Compared  with  the  eastern  cinereola,  the  present  species  is  stouter 
in  body,  with  narrower  wings.  The  general  scheme  of  maculation 
is  identical,  but  the  contrasts  are  much  greater.  While  there  is  an 
evident  resemblance  there  can  be  no  danger  of  confusion  with  the 
eastern  form. 

Dr.  Harvey’s  navia  has  a tuberculated  front  and  anned  fore  tibiai, 
and  belongs,  therefore,  with  the  Stiriin^.  It  may  be  best  referred 
to  Stibadium  for  the  present. 

As  Mr.  Grote  has  recently  avowed  his  responsibility  for  Dr.  Har- 
vey’s species,  the  failure  to  see  the  obvious  structural  characters 
separating  this  species  generically  from  cinereola,  is  chargeable  to 
the  former. 


I*liisia  augiilidens  n.  sp.— Head,  thorax  and  primaries  bluish  gray  in 
ground  color,  with  fuscous  powderings.  Collar  with  a median  and  subterminal 
fuscous  line,  and  the  patagise  have  also  two  rather  diffuse  transverse  lines.  Tho- 
racic tuft  brown,  basal  abdominal  tuft  almost  black,  but  with  a white  margin. 
Primaries  with  the  basal  line  distinct,  black,  geminate,  inwardly  oblique  from 
the  costa.  T.  a.  line  inwardly  oblique,  with  three  feeble  outcurves,  outer  line 
black,  inner  vague,  and  marked  on  the  costa  principally,  though  also  traceable 
below  internal  vein  ; the  line  is  interrupted  on  the  median  vein,  where,  at  the 
origin  of  vein  2,  the  greenish  silver  u is  attached,  much  as  in  ou.  A very  small 
silver  dot  follows,  but  is  completely  and  even  widely  separated.  The  median 
space  is  vaguely  and  irregularly  fuscous  shaded.  T.  p.  line  oblique,  almost  par- 
allel with  the  outer  margin,  irregularly  aiid  feebly  angulate  outwardly  ; the  line 
is  whitish  centered,  the  geminate  defining  lines  fuscous.  S.  t.  line  prominent, 
black,  irregularly  and  widely  angulated  and  dentate,  shading  off  by  a fuscous 
tinge  into  the  s.  t.  space,  hut  sharply  contrasted  against  the  bluish  gray  terminal 
space.  This  character  forms  the  most  obvious  feature  in  the  ornamentation.  A 
fuscous  shading  near  outer  margin,  forming  irregular  patches  snbapically. 
Fringes  gray,  cut  with  fuscous.  Orbicular  a very  vague,  oval,  oblique  spot.

Hab.  —Colorado  ( Bruce). 

The  species  is  allied  to  P.  viridislc/nata  Grt.,  or  yet  more  cliKsely  to 
celsa  Itdw.,  of  the  latter  of  which  iNIr.  Neumoegen  has  the  type.  It 
differs  from  both  iu  the  greater  prominence  and  angulation  of  the 
s.  t.  line,  and  from  the  latter  in  the  less  distinct  transverse  macula- 
tion,  and  the  want  of  the  black  shadings  described  by  Mr.  Edwards. 
The  underside  of  the  new  species  does  not  agree  at  all  with  what 
that  of  cebsa,  next  to  which,  however,  it  must  probably  stand.  Sev- 
eral specimens  were  taken  by  Mr.  Bruce,  who  has  also  taken  F. 
snowi  in  .some  numbers. 

Cirrhophiiiies  diiplicatiis  n.  sp. — Ground  color  pale  ocher  yellow,  with 
the  niaculation  deeper,  orange  yellow.  Head  and  thorax  immaculate,  the  tho- 
racic tuftings  orange  tipped.  Primaries  with  a coppery  flush  over  costal  region 
to  middle  of  wing,  and  in  discal  cell.  Ordinary  lines  single.  Basal  line  l)avely 
visible.  T.  a.  line  widely  angulated  on  subcostal  vein,  in  submediau  interspace, 
and  again  to  the  hind  margin.  T.  p.  line  even  or  very  feebly  lunate,  widely 
outcurved  over  cell,  then  very  obliquely  inward  to  the  middle  of  the  hind  mar- 
gin. S.  t.  line  very  di.stinct,  broader  than  the  others,  even,  parallel  with  outer 
margin.  A rich  orange  line  at  base  of  fringes.  A somewhat  deeper  shading 
through  the  terminal  space.  All  the  veins  orange  marked.  Ordinary  spots  ob- 
solete. Secondaries  ocherous,  paler  at  base,  and  with  an  orange  terminal  line. 
Beneath,  primaries  reddish  ocberou.s,  secondaries  pale,  powdery.  Expands  1.16 
inches ; 29  mm. 

Hab. — Platte  Canon,  Col.,  6500  feet. 

This  species,  collected  by  Mr.  Bruce,  is  before  me  in  one  female 
specimen  only.  It  is  somewhat  smaller  than  triangulifer,  and  lacks 
altogether  the  rich  tinting  of  that  species.  In  niaculation  the  two 
are  very  much  alike.  The  frontal  jtrotuberance  of  the  new  sjiecies 
consists  of  a simple  nipple-like  dilation,  differing  quite  strongly  from 
trianc/u lifer,  and  the  fore  tibite  seem  unarmed.  The  specimen  is  im- 
perfect iu  leg  structure — most  of  the  legs  wanting — and  the  claw 
may  have  been  broken  off.  In  thoracic  tufting,  wing  form  and  gen- 
eral habitus,  this  species  is  the  close  ally  of  its  congener. 

The  specimen  is  in  the  United  States  National  Museum. 

Ori'liodia  Ciilitorniea  u.  sp.— Head,  thorax  and  primaries  a deep,  rather 
sordid  luteous  brown,  with  clo.se,  black  powderings  beyoud  the  t.  p.  line,  dark- 
ening the  primaries  terminally.  Head  and  thorax  immaculate.  Basal  line 
scarcely  traceable.  T.  a.  line  geminate,  defining  lines  a series  of  black  scales, 
included  space  pale:  in  course  the  line  is  outwardly  oblique  and  outcurved  be- 
tween the  veins.  T.  p.  line  geminate,  pale,  the  defining  lines  blackish,  very

even,  its  general  course  bisinuate,  outcurved  over,  incurved  below  tbe  cell. 
Througb  the  dusky  outer  portion  of  the  wing  the  veins  are  pale,  and  the  irregu- 
lar, indefinite  concolorous  s.  t.  line  is  rather  indistinctly  traceable.  A row  of 
black  terminal  lunules.  Fringes  with  a pale  line  at  base.  Claviform  vaguely 
indicated  by  fuscous  brown  scales.  Orbicular  upright  oblong,  pale  ringed  and 
dusky  powdered;  reniforin  large,  slightly  constricted  centrally,  pale  ringed  and 
black  powdered.  Secondaries  even,  fuscous  brown.  Beneath  fawn  gray,  pow- 
dery ; secondaries  paler  basally ; both  wings  with  an  outer  line  and  dusky  discal 
lunule.  Expands  1.36  inches  ; 34  min. 

Hab. — Sierra  Nevada,  Cal. 

A single  male  from  Mr.  Edwards’  collection  with  “ brush-like” 
antenme.  In  habitus  and  appearance  this  species  resembles  a Tcenio- 
campa,  but  the  eyes  are  naked  and  strongly  lashed.  It  is  congeneric 
with  the  European  0.  silene,  and  seems  distinct  from  our  species  of 
Gkea  and  allies. 

In  introducing  the  term  Orrhodia  into  our  fauna  I do  it  not  to 
replace  any  term  now  in  use,  but  because  it  seems  as  though  it  really 
refers  to  a tyjie  different  from  the  others  heretofore  noted.  The  Eu- 
ropean species  .seem  very  unlike  each  other  and  may  not  be  held 
together.  On  the  other  hand  additional  material  of  the  species 
before  me  may  indicate  another  genus.  The  type  is  perfect,  exce|)t 
that  one  antenna  is  missing. 

l*LEROMA  11.  geu. 

Eyes  naked,  with  long  hairy  lashes.  Head  retracted,  moderate  in 
size,  with  divergent  hairy  vestiture,  palpi  short,  scarcely  e.xceediug 
the  frontal  vestiture,  divergently  clothed.  Tongue  moderate,  spiral. 
Thorax  quadrate,  heavy,  vestiture  long,  somewhat  flattened  hair; 
collar  somewhat  [iroduced  in  front,  forming  a central  crest ; an  in- 
definite loose  posterior  tuft.  Breast  densely  clothed  with  long  woolly 
hair.  Legs  unarmed,  short,  stout,  with  dense,  long  woolly  hair  on 
femora  and  tibise.  Abdomen  with  dorsal  tuftings,  short,  stout,  conic 
in  the  female  and  scarcely  exceeding  hind  angles  of  the  secondaries 
in  either  sex.  Antenme  simple  in  both  sexes.  Primaries  trigonate, 
comparatively  short  and  broad,  with  produced  apices  and  a verv  ob- 
lique, evenly  curved  outer  margin,  joining  with  the  inner  margin  at 
a very  obtusely  rounded  angle.  Secondaries  proportionate,  fringes 
long. 

I could  not  satisfactorily  refer  the  species  with  the  above  comliina- 
tion  of  characters  to  any  of  the  described  genera.  It  is  evidently 
related  to  Xylhia  without  the  depressed  form  and  narrow  wings.

while  the  type  of  oriiainentation  is  different  from  any  other  species 
of  this  series  wliich  is  known  to  me,  approaching  that  of  Cucul/ia. 

I*,  obliqiiata  n.  sp. — Bluish  ash-gray,  varying  in  depth  of  tint  from  whitish 
to  very  deep,  almost  blackish.  Collar  with  a central  white  line  between  two 
black  lines,  which  in  a pale  specimen  is  reduced  to  a central  black  line  and  a 
fuscous  upper  line.  Thorax  with  black  hair  intermixed,  but  forming  no  distinct 
ornamentation.  Primaries  with  all  the  veins  black  marked.  T.  a.  line  single, 
quite  broad,  outcurved,  but  distinct  only  into  the  submedian  interspace  and  not 
attaining  the  inner  margin.  T.  p.  line  single,  fuscous  to  black,  almost  parallel 
with  outer  margin,  followed  by  a narrow  pale  shade.  An  oblique,  broad,  dusky 
shade,  sometimes  broken  up  into  spots  from  the  apex  to  the  hind  margin  near 
the  t.  p.  line.  S.  t.  line  vague,  broken,  in  pale  specimens  marked  only  by  pre- 
ceding black  interspaceal  marks.  A dusky  line  at  base  of  fringes,  which  alter- 
nate in  two  very  slightly  different  shades  of  gray  and  have  a pale  central  line. 
The  ordinary  spots  are  wanting,  only  the  reniform  being  vagviely  indicated  by 
a dusky  shade,  more  evident  in  pale  specimens.  Secondaries  pale  fuscous  to 
smoky  brown,  with  darker  veins  and  a dusky  discal  spot.  Fringes  pale,  with  a 
du.sky  interline.  Beneath,  primaries  blackish  or  smoky,  white  powdered  out- 
wardly; secondaries  paler,  more  powdery,  with  an  outer  dark  line  and  dusky 
discal  spot.  Expands  1.28 — 1.32  inches;  32 — 33  mm. 

H(tb. — Sierra  Nevada,  Cal. ; Colorado. 

Both  sexes  are  before  me,  the  California  specimen  frotn  Mr.  Ed- 
wards, the  others  collected  by  Mr.  Bruce.  The  California  specimen 
is  a much  paler  gray  and  the  maculation  is  more  distinct,  but  there 
does  not  seem  to  be  any  other  difference,  and  I can  scarcely  think 
them  distinct.  I consider  the  Colorado  specimens  represented  in  the 
National  Museum  collection  yyjiical  of  the  species  and  the  Califor- 
nian as  a race.

Eyes  naked,  large,  globose,  scarcely  prominent.  Head  moderate, 
frontal  vestitnre  scaly,  projecting,  but  forming  a smoothly  rounded 
sui’face.  No  frontal  modification.  Tongue  moderate,  corneous; 
palpi  stout,  normally  noctuidous  in  form,  reaching  to  the  middle  of 
front  in  the  male,  a little  shorter  in  the  female.  Antenme  simple  in 
both  sexes,  finely  ciliated  laterally.  Thorax  small,  convex,  vestitnre 
flattened  hair  and  scales,  smooth,  forming  no  tuftings.  Abdomen 
smoothly  scaled,  untufted.  Legs  stout,  with  rather  thick  scaly  ves- 
titure,  tibiie  not  spinose,  anterior  unarmed.  The  primaries  are  large, 
l)road,  with  arched  costa  and  rounded  apices  and  outer  margin.  The 
inner  margin  is  nearly  as  long  as  the  costa.  Secondaries  propor-

This  genus  has  a very  decided  hahital  resemblance  to  Orfhodes, 
but  differs  at  once  by  the  naked  eyes.  The  species  u]jon  which  tlie 
genus  is  based  has  been  known  to  me  for  .several  years.  It  is  in  the 
collection  of  the  United  States  National  iNluseum,  taken  as  far  back 
as  1882,  and  I have  received  it  for  name  several  times.  I have  tried 
to  identify  it  with  all  genera  or  species  to  which  it  could  have  been 
reasonably  referred,  but  cannot  find  any  description  to  cover  it,  nor 
do  I find  it  named  in  any  collection  thus  far  examined.  It  may  be 
confused  under  Orthodes  cxjnica,  to  which  it  bears  some  resemblance. 
I have  named  the  form. 


Aiiorf  liodes  prima  n.  sp. — General  color  a soft,  even  mouse  gray.  Head 
and  tliorax  immaculate.  Primaries  with  all  the  lines  evident,  the  basal,  t.  a. 
and  t.  p.  single,  line,  blackish,  the  s.  t.  broader,  pale.  Basal  line  nearly  strait^ht. 
T.  a.  line  with  a decided  inward  angle  on  the  cell,  irregularly  oblique  below. 
T.  p.  line  outcurved  over  cell,  somewhat  incurved  below;  it  is  even  or  sli<Thtlv 
crenulated.  S.  t.  line  yellowish,  irregular,  as  a whole  closely  parallel  to  the  outer 
margin.  A vague  blackish  median  shade  line,  often  ditfuse,  obtusely  angulate 
on  the  reniform,  quite  rigid  below  to  the  hind  margin.  Claviform  wautino-. 
Orbicular  punctiform  blackish.  Keniform  an  indefinite  blackish  lunule.  some- 
times not  distinct,  marked  with  a few  whitish  scales.  A very  faint,  yellowish 
terminal  line.  Secondaries  very  faint  smoky  gray,  shining.  A vague  discal 
lunule  and  a very  distinct  yellow  line  at  the  ba.se  of  the  somewhat  paler  fringes. 
Beneath,  glistening  gray,  powdery,  somewhat  darker  on  primaries,  both  wings 
with  a variably  complete  and  distinct  outer  line  and  discal  lunule.  Expands 
1.12—1.20  inches.  28—30  mm.

September  2d  and  12th  (U.  S.  Nat.  Mus.) ; Columbus,  O.  (Tallant). 

Under  the  number  3503,  bred  specimens  are  in  the  biological  col- 
lection (coll.  C.  V.  R.)  and  the  life-history  has  been  made  out. 

There  should  be  no  difficulty  in  recognizing  this  species  by  the 
soft  color  and  single,  line  median  lines.  The  harpes  are  broad,  up- 
curved  at  tip,  a small  corneous  process  at  inferior  angle,  where  also 
the  surface  is  set  with  acute  teeth  ; a stouter  and  longer  corneous 
spur  from  below  the  middle  of  the  harpe  inclined  upward  and  in- 
ward, or  exactly  opposite  the  other  spur.

Triclioelea  po*$tica  n.  sp. — Pale,  somewhat  creamy  white,  with  a faiut 
luteous  admixture,  powdery.  Primaries  with  all  the  maculation  faintly  written, 
blackish.  Basal  line  marked  on  costa  by  a geminate  black  spot,  and  again  faintly 
below  the  median  vein.  T.  a.  line  upright,  geminate  on  costa  only,  lunulate, 
preceded  by  a variably  obvious  pale  shade.  T.  ]).  line  also  marked  by  costal 
dots,  thence  single,  crenulated,  outcurved  over  reniform,  rather  evenly  oblique, 
or  with  but  a slight  incurve  below.  This  line  is  also  accompanied  by  a somewhat 
paler  shade,  and  a series  of  pale  venular  dots  outwardly.  S.  t.  line  marked  on

costa,  but  very  vaguely  below,  becoming  in  one  case  scarcely  traceable,  in  the 
other  fairly  detined  by  a dusky  preceding  shade.  A series  of  blackish  terminal 
lunules.  Claviform  small,  imperfectl.v  outlined,  concolorous.  Orl)icular  want- 
ing, or  but  faintly  indicated,  then  oval,  rather  small.  Reniform  large,  upright, 
kidney-shaped,  laterally  only  defined,  with  a central  fuscous  lunule,  which 
expands  somewhat  inferiorly.  A vague  median  shade  through  the  outer  part  of 
median  sjiace.  Secondaries  in  the  male  white,  veins  fuscous  marked  ; a narrow 
dusky  outer  margin  ; a distinct  discal  lunule.  Secondaries  in  the  female  dusky, 
smoky  brown,  somewhat  paler  basally,  fringes  white.  Beneath  white,  powdery, 
with  a variably  distinct  crenulate  outer  line  and  discal  spot.  Expands  1.40  in- 
ches; 35  mm. 

Hab.  — Denver,  Col.  (Bruce). 

Male  ami  female  are  before  me,  the  former  from  the  coll.  U.  S. 
Nat.  Museum  (two  specimens),  the  latter  from  Mr.  Neumoegen.  The 
frontal  jirotuberance  is  quite  prominent,  the  armature  of  the  fore 
tarsi  much  as  in  decepta  rather  than  edwardsil.  The  male  genitalia 
are  similar  to  those  of  the  other  species,  and  best  described  by  a 
reference  to  figure  5 on  PI.  II,  with  which  should  be  compared  also 
PI.  XXII,  figs.  18  and  19,  Proc.  U.  S.  Nat.  Mus.  vol.  xii. 

Triclioclea  aiitica  n.  sp. 

Every  word  of  the  description  of  postica  will  apply  as  well  to  this 
species,  save  that  the  secondaries  of  the  male  are  less  soiled,  more 
purely  white,  and  in  the  female  the  .secondaries  ax'e  like  those  of  the 
male  postica;  otherwise  the  maculation  is  the  same,  and  I should 
have  considered  the  specimens  identical,  but  for  the  fact  that  the 
frontal  protuberance  is  much  smaller,  less  prominent,  the  tarsal  ar- 
mature weaker  even  than  in  edwardsii,  and  finally  the  male  struc- 
tures differ  quite  strongly,  first  in  absolute  size,  those  of  the  ])resent 
species  being  fully  one-third  larger  from  the  same  sized  male  and 
also  in  the  arrangement  of  the  corneous  claspers,  which  differs  from 
all  of  the  other  species,  and  is  figured  on  PI.  II,  fig.  4.  Expanse 
as  in  postica. 

Hab. — Los  Angeles  County,  Cal.,  April  10th  ; good  specimens  are 
in  the  National  Museum  collection  (through  C.  V.  Riley). 

Tteniocaiiipa  orobia  Haw. 

This  insect  I could  not  find  in  the  INIeske  collection,  from  which 
it  was  described,  when  I wrote  my  Revision  (Proc.  U.  S.  Nat.  Mus. 
xii,  455-496,  1889).  The  completed  incorporation  of  the  collection 
into  the  regular  museum  series  has  bi’ought  to  light  the  typical  Texas 
specimen,  and  it  turns  out  to  be  exactly  like  specimens  of  oviduca,

to  which  it  must  be  cited  as  a synonym.  Mr.  Grote  claims  credit 
for  Dr.  Harvey’s  descriptions,  and  he  must  be  charged  with  this 
synonym. 

T.  pacifica  Harv. 

The  museum  has  received,  tlirough  Dr.  Riley,  four  specimens  of 
this  species  from  Alameda  County,  Cal.,  January,  February  and 
March,  and  with  the  red  number  334.  The  specimens  are  all  males, 
and  confirm  the  opinion  that  we  have  to  do  with  a good  species  and 
not  a variety  of  the  eastern  form.  The  characters  pointed  out  by 
me  hold  good,  save  that  the  orbicular  may  be  as  dark  as  the  reui- 
form.  As  the  whole  the  specimens  look  more  robust  and  are  darker, 
more  powdery. 

Ta^iiiocainpa  aiiutiliinaciila  n.  sp.— Ground  color  pale  fawn  gray;  a 
fine  soft  tint.  Head  and  thorax  immaculate.  Primaries  with  basal  and  t.  a. 
lines  wanting.  T.  p.  Hue  a curved  series  of  small  venular  dots.  S.  t.  line  rather 
irregular,  concolorous  or  slightly  paler,  marked  by  a somewhat  darker  preceding 
shade  (rarely  the  line  will  be  entirely  wanting).  A narrow  median  shade  line, 
bent  on  the  reniform,  also  sometimes  wanting.  Orbicular  concolorous,  usually 
obsolete,  sometimes  outlined  by  ferruginous  scales,  moderate,  round.  Eeniform 
large,  upright,  concolorous,  more  or  less  completely  defined  by  a rusty  red-brown 
annulus,  always  distinct  at  the  outer  side  at  least,  and  forming  the  only  obvious 
bit  of  maculation  on  the  entire  wing.  Secondaries  very  pale  powdery  fawn  gray, 
with  a faint,  darker,  discal  lunule.  Beneath  pale,  powdery  fawn  gray ; primaries 
with  a discal  dot  and  a more  or  less  evident,  sometimes  obsolete  outer  line.  Sec- 
ondaries with  a distinct  discal  spot.  Expands  1.68  inches  ; 39 — 42  mm. 

Hab. — Texas,  February  17th,  19th  and  25th  (Belfrage). 

Five  good  specimens  are  in  the  National  Museum  collection  ('coll. 
C.  V.  R.).  The  antennae  of  the  male  are  lengthily  bipectinated,  the 
habitus  and  wing  form  as  in  my  pectinata,  to  which  this  species  is 
allied.  The  very  pale  fawn  gray  color,  the  lack  of  all  prominent 
maculation,  save  the  rusty  ring  to  the  reniform,  and  the  plump,  woolly 
thorax,  will  readily  identify  this  form.  It  bears  a casual  resemblance 
in  habitus  to  Copipanolis,  and  the  assignment  of  the  specimens  to 
that  series  by  the  collector  caused  me  to  overlook  them  in  my  studies 
on  the  Museum  material  previously. 

The  male  characters  are  distinctive.  The  harpes  narrow  toward 
tijh  which  is  somewhat  drawn  out  superiorly  into  an  acute  point.  A 
stout,  curved,  corneous  process  frojn  the  middle  of  the  outer  third,  a 
smaller  process  at  its  base  inferiorly  and  a longer  stouter  curved  pro- 
cess from  behind  the  middle  of  upper  margin.

I notice  that,  by  some  accident,  group  palilis  is  omitted  in  my 
Revision  of  Tteniocampa,  though  the  characters  of  the  group  are

Tieiiioeampa  pectiiiata  Smith. 


When  I described  this  species,  from  scant  material,  there  was  a 
rubbed  and  faded  male  s])ecimen  in  the  coll.  U.  S.  Nat.  Mus.,  which 
I identified  with  this  form,  and  from  which  the  figure  of  the  sexual 
characters  was  made.  Since  that  time  new  material  has  been  re- 
ceived, and  I have  described  the  genus  Perigonica,  to  which  I find, 
on  renewed  study,  the  supposed  T.  pectlnata  belongs.  A number  of 
fresh,  clean  specimens  of  the  latter  enable  me  to  give  a correct  figure 
of  the  sexual  characters,  and  for  comparison  I add  the  figures  of 
Perigonica  angulata  and  P.  falminans,  all  from  typical  specimens.

This  genus,  among  others,  was  monographed,  our  American  species 
alone  considered,  in  the  Proc.  U.  S.  Nat.  Museum  xii,  490,  and  I 
there  called  attention  to  the  fact  that  our  species  did  not  in  all  re- 
spects agree  with  the  European  tyjies.  I have  since  received  a speci- 
men which  fills  all  the  requirements  of  the  generic  description,  and

The  genus  Perigrapha  will  he  re])resented  in  our  fauna  by 

I*,  priina  ti.  sp.  — Deep  bluish  asli-gray,  with  a fuscous  powdering.  Front  of 
head  and  base  of  collar  discolorous  yellow  fuscous;  patagise  obscurely  black  mar- 
gined B;isal  line  obscurely  marked,  scarcely  traceable.  T.  a.  line  geminate, 
fuscous,  evenly  oblique  outwardly.  T.  p.  line  geminate  fuscous,  interrupted, 
quite  faint,  evenly  bisinuate.  A vague,  narrow  fuscous  shade  through  the  centre 
of  the  median  space.  Costal  half  of  basal  space  paler  ash-gray.  Claviform 
wanting.  Ordinary  spots  large,  subequal,  oblong,  oblique,  touching,  but  not  quite 
confluent  inferiorly,  narrowly  fuscous  margined,  filled  with  paler  gray,  reniform 
somewhat  stained  with  reddish.  Beyond  the  middle  of  the  s.  t.  space  the  wing 
is  much  paler  gray,  contrasting  asiainst  the  bluish  of  the  rest  of  the  wing;  the 
irregular  faint  s.  t.  line  traceable  by  a powdering  of  black  scales.  A series  of 
blackish  terminal  lunules.  Secondaries  even,  smoky  fuscous.  Beneath,  smoky 
brown,  secondaries  pale  powdered,  both  wings  with  an  outer  line  and  discal  spot.

A single  female  specimen  from  Mr.  Hy.  Edwards  in  which  the 
antennte  are  lengthily  serrate  or  very  shortly  pectinated. 

The  large  ordinarv  spots  and  discolorous  pale  terminal  space, 
combined  with  the  generic  characters,  will  render  this  species  easily 
recognizable.  \ \ 

Strotcliia  variabilis  n.  'sp.  -Ground  color  dark  ash-gray  with  black 
powderings.  Head  and  front  of  collar  umber  brown,  collar  wdiite  tipped,  with  a 
crested  black  line.  The  small  thoracic  tuftiugs  and  the  abdominal  tufts  blackish 
brown  to  black.  Abdomen  dark  fuscous.  Basal  line  geminate  black,  evident. 
T.  a.  line  pale,  geminate  on  costa,  obliquely  and  regularly  outcurved  to  vein  1, 
and  agaiT)  outcurved  below  that  vein.  T.  p.  line  rather  indefinite,  inw'ai’dly  de- 
fined by  a variably  distinct  lunate  black  line,  wddely  outcurved  over  cell,  and  as 
deeply  incurved  below,  so  that  the  median  space  on  inner  margin  is  only  half 
the  width  through  the  cell.  This  median  space  may  be  coucolorous,  only  slightly 
darker,  bright  umber-brown,  or  almost  black.  The  claviform  is  w'anting.  Or- 
bicular large,  rather  irregularly  oval,  oblique.  Reniform  large,  kidney-shaped, 
both  the  spots  narrowiy  black  ringed,  almost  coucolorous,  suffused  with  reddish, 
or  nearly  white,  contrasting.  S.  t.  line  powdery  gray,  irregular,  vague,  marked 
opjiosite  the  anal  angle  with  a more  evident  blackish  lunule,  follow'ed  by  ocher- 
ous  or  paler  yellow  scales.  S.  t.  space  slightly  darker  costally.  A series  of  small 
terminal  dots,  beyond  wiiich  the  fringes  are  cut  with  pale  gray.  There  is  a short, 
curved  basal  black  Hue  which  does  not  extend  to  the  t.  a.  line,  and  the  veins  are 
all  black  marked.  Secondaries  whitish,  quite  heavily  black  powdered,  with 
.soiled  veins,  a blackish  discal  lunule,  and  a blackish  marginal  line.  Beneath 
pale,  with  black  powderings,  the  primaries  darker,  both  wings  with  a dusky 
outer  line  and  discal  lunule;  secondaries  also  with  a marginal  line.  On  the  pri- 
maries the  outer  line  is  not  complete  and  may  be  entirely  wanting,  and  the  discal 
spot  varies  in  size  and  distinctness.  Expands  1..52 — 1.(10  inches  ; 38 — 40  mm.

Several  specimens  are  before  me  from  Mr.  Jseumoegen  and  Mr. 
Bruce,  and  n<)  two  of  them  are  alike.  One  male  bears  a deceptive 
resemblance  in  maculation  to  Valeria  grotei,  the  dark  color  and  con- 
trasting white  ordinary  spots  causing  the  likeness,  others  have  a very 
decided  reddish  suffusion  through  the  median  space  and  some  are 
entirely  concolorous,  even,  blackish  gray. 

The  ordinary  spots  are  sometimes  well  separated,  usually  quite 
close  together,  rarely  confluent  inferiorly.  The  vestiture  is  scaly, 
and  in  appearance  the  species  is  associated  with  my  first  group  in 
which  the  ordinary  spots  are  usually  fused.  It  is  readily  distinguished 
from  all.  The  male  genitalia  are  unlike  the  others  of  the  genus. 
The  harpes  are  narrow,  the  tip  somewhat  produced  superiorly.  The 
clasper  consists  of  a corneous  hook  with  a basal  short  s])ui\ 
belirensisina  Grt. 

This  species,  unknown  to  me  in  1889,  I have  identified  in  speci- 
mens sent  me  by  Mr.  Edwards  for  name.  It  agrees  well  with  the 
description,  but  varies  excessively  in  distinctness  of  maculation,  in 
ground  color  and  in  the  amount  of  black  powdering.  The  sexual 
characters  are  unlike  any  figured  in  my  Revision  (Proc.  U.  S.  Nat. 
Museum  xii,  pi.  xxii,  figs.  1-5),  but  resemble  most  nearly  those  of 
normalis,  save  that  the  clasper  is  double. 

In  the  Verb.  k.  k.  zool.-bot.  Gesell.  in  Wien,  1872,  p.  502,  Zeller 
describes  Sedenia  (cavifrous)  blundulalis,  a Pyralid.  He  says  of  it: 
“ Frans  conica,  superne  cornea,  excavata,"  using  this  character  to  ally 
it  with  cervalis.  The  specific  diagnosis  is  short  and  characteristic : 
■■  Alls  albis,  anterioribus  serieeis,  strigis  duabus  crassis,  undulatis,  nigris 
$ .”  The  description  is  full  and  careful,  and,  in  connection  with 
the  figure  given  on  pi.  iii,  fig.  1-f,  leaves  no  doubt  that  the  s])ecies 
before  me  is  really  that  intended  by  Zeller.  The  locality,  Texas,  is 
also  identical.  Mr.  Grote  has  omitted  the  genus,  and  apparently  the 
species  as  well,  in  his  List  of  1882.  A few  days  ago  Mr.  Hulst 
handed  me  the  insect,  with  the  remark  that  Prof.  Feruald  said  it 
was  a uoctuid.  A glance  at  the  habitus  convinced  me  that  this  was 
so,  and  that  I had  a close  relative  to  some  forms  which  had  been  in 
my  hands  for  name  for  some  time.  Zeller’s  description  points  so 
convincingly  to  a Pyralid  that  it  could  leave  no  feeling  of  doubt  on 
the  reader.  He  says,  among  other  matters,  that  the  maxillary  palpi 
are  small,  brown,  resting  on  the  labial  pal[)i.  An  examination  of 
my  specimen  shows  a curious  error,  induced  probably  by  the  con- 


NORTH  AMERICAN  LEPIDOPTERA. 


]21 


viction  that  the  species  must  have  maxillary  palpi.  As  a matter  of 
fact  the  supposed  palpi  are  merely  the  projecting  and  somewhat 
thickened  edges  of  a Hat,  plate-like  clypeal  process,  arising  below 
the  frontal  tubercle.  The  single  ? possessed  by  Zeller  must  also 
have  been  rather  imperfect,  since  he  failed  to  note  the  fact  that  the 
fore-tibipe  were  armed  at  tip  with  a long  inner  and  shorter  outer 
spine  or  claw,  though  the  color  and  structure  are  otherwise  accurately 
described. 

Referred  to  the  Noctuidie  the  relation  to  Antaplarja  sexseriata  Grt. 
is  at  once  obvious,  and  to  this  genus  Zeller’s  species  must  be  referred, 
as  A.  biundulata  Zell.  It  differs  from  the  described  species  in  the 
presence  of  the  clypeal  plate  below  the  tubercle,  but  this  will  scarcely 
warrant  generic  separation.  From  A.  sexseriata,  which  it  closely 
resembles  in  maculation,  it  differs  in  the  somewhat  heavier  bands, 
and  in  the  absence  of  the  subterminal  black  dots. 

THYREIOK  n.  geu. 

Body  plump,  robust,  thorax  with  thin  hairy  vestiture.  Head  re- 
tracted, front  flat;  palpi  short  and  weak,  scarcely  exceeding  the 
front;  tongue  moderate  in  length  ; antennae  of  % stout,  rather  short, 
with  short,  thick  lateral  teeth.  Tibiie  spinose,  clothed  with  i-ather 
long  thin  hair  ; anterior  pair  abbreviated,  broad  at  tips,  with  a single 
long  inner  claw,  and  a series  of  two  or  more  along  the  outer  edge. 
Primaries  proportionately  short  and  small,  the  co.sta  concave,  apices 
somewhat  drawn  out,  outer  margin  oblique,  scarcely  convex  out- 
wardly. 

d'his  genus  is  to  replace  Aedophron  as  used  by  Mr.  Grote.  I 
pointed  out  eight  years  ago  that  Mr.  Grote’s  species  snowi  could  not 
be  referred  to  Lederer’s  genus,  but  as  I had  no  specimens  I made  no 
change  in  the  reference.  Mr.  Grote,  in  his  List  of  1890,  has  made 
no  change  in  the  generic  location  of  the  species,  though  he  has  based 
a number  of  new  genera  on  characters  pointed  out  for  him  by  others. 
The  occurrence  of  a new  species,  close  to  snowi,  enables  me  to  give 
the  above  description.  The  genus  Aedophron  retains  as  its  single 
American  representative, Tepper,  differing  from  the  European 
representative  as  already  pointed  out  by  me. 

Th.  rosea  .sp.  nov. — Head  and  thorax  a rather  sordid  pale  lemon-yellow; 
abdomen  deep  blackish  gray.  Primaries  above,  yellow  to  the  s.  t.  space,  thence 
rosy  red  to  the  outer  margin,  receiving  an  admixture  of  yellow  outwardly; 
fringes  pink  ; a ray  of  rosy  red  extends  through  the  cell,  joining  the  marginal

shade,  and  a similar  ray  from  the  same  point  extends  through  the  submedian 
interspace,  also  joining  the  marginal  hand.  Secondaries  above,  a deep  blackish 
gray,  with  pale  rosy  fringes.  Beneath,  primaries  deep  blackish  gray;  seconda- 
ries paler,  flushed  with  pink  aloiig  the  costa,  and  a very  decided  rosy  shade  ex- 
tending from  the  apex  along  the  outer  margin  nearly  to  the  anal  angle.  Expands 
1 inch  : 25  mm. 

Hab. — Colorado  (Bruce). 

The  single  male  from  which  this  description  is  made  is  from  Mr. 
Neumoegen’s  collection,  hut  I think  I have  seen  others,  also  of  Mr. 
Bruce’s  collecting,  from  the  same  locality.  The  species  should  not 
he  difficult  to  identify. 

XAMTHODES  Gn. 

A somewhat  peculiar  genus,  resembling  in  its  form  and  habitus 
Chariclea  and  Aedophron,  but  didering  in  venation,  form  of  palpi, 
etc.  Of  medium  size,  slender,  the  entire  insect  somewhat  depressed  ; 
front  with  a smooth,  horizontally  [irojecting  conic  tuft;  tongue  spiral. 
Eyes  large  and  naked,  anteniue  thin,  bristle-form,  in  the  male  with 
short  fine  ciliie.  Palpi  slender,  apparently,  from  the  smooth  close 
vestiture,  of  equal  thickness,  converging,  somewhat  upcurved,  then 
projecting  in  the  form  of  a snout  beyond  the  palpi.  Collar  convex 
close  to  the  dorsum  and  through  the  fine  hairy  vestiture  scarcely  to 
be  distinguished  from  it.  Abdomen  smooth,  with  thin  vestiture. 
Legs  strong,  unarmed  and  closely  scaled,  only  the  outside  of  the 
tibiie  with  dense,  woolly,  thick  hair.  Primaries  without  accessory 
cell,  6,  7-8  and  9-10  out  of  the  tip  of  the  median  cell  ; broad,  with 
feebly  arcuate  outer  margin.  Secondaries  with  vein  5 weak. 

The  above  is  a close  translation  of  Lederer’s  description  of  the 
genus  which  has  been  introduced  into  our  fauna  by  Mr.  Grote  for 
his  species  Schinia  buxea;  the  genus  Trileuca  being  [iroposed  for 
Schinia  rectifascia  and  S.  gnluare  Strk.  In  the  “ Revised  Check 
List”  S.  gubuire  is  referred  to  Lygranthcecia,  to  which  it  does  not 
belong,  while  buxea  and  redifacla  go  into  Trileuca  and  are  refei’red 
to  the  Acontiiiue.  S.  gulnare  Mr.  Grote  did  not  know,  and  was,  of 
course,  justified  in  leaving  it  where  its  author  put  it.  Trileuca  may 
be  a good  genus,  but  it  does  not  belong  to  the  Acontiiiue.  Its  rela- 
tions are  with  Calynuiia.  and  Cosinia,  or  perhaps  very  near  to  Atethmia. 
Xanthodes,  as  based  on  the  Eui’opean  type,  is  unlike  either  of  the 
species  associated  with  it  by  IMr.  Grote,  and  I do  not  know  of  any 
American  species  that  could  be  properly  referred  to  it. 

Mr.  G rote  makes  a very  touching  plea  for  his  genus  Lygranthcecia 
in  the  Proc.  Am.  Philos.  Soc.  1888,  173,  but  does  not  show  anywhere 


NORTH  AMERICAN  LPHHDOPTERA. 


123 


that  it  has  any  right  at  all  under  the  laws  of  priority.  Mr.  Grote 
has  always  been  a strict  Hiibnerian,  but  now,  when  one  of  his  genera 
is  to  be  superseded,  it  becomes  “ unjust  and  against  the  usual  comity 
and  practice !” 

But  even  suppose  Hiibner’s  genus  should  not  be  adopted,  how  can 
we  get  over  Guenee’s  genus  Tamila  proposed  in  1852  with  nundnia 
as  the  type?  One  of  the  very  species  which  Mr.  Grote  now  includes 
under  Lygraathoecia  ! and  why,  if  “comity”  is  to  be  shown,  should 
Boisduval’s  Anthcecia  be  sacrificed,  the  very  first  sjiecies  being  Mr. 
Grote’ s present  type  of  Lygranihcecia.  To  be  sure  the  designated 
types  of  Anthcecia  and  Melicleptria  are  the  same,  but  “ comity”  would 
seem  to  re<juire  that  Anthcecia  should  be  retained  for  some  species  if 
possible.  And  why  should  Hiibner  be  enforced  against  Boisduval 
and  not  against  Grote? 

For  the  present  I cannot  see  my  way  to  the  use  of  Lygranthcecia 
in  preference  to  Schlnia  or  Tamila. 

Before  describing  the  species  of  Schinia  before  me,  an  ally  of 
Schinia  (Trileuca)  buxea  merits  attention. 

Trileiica,  deiitalis  n.  sp.  — Head,  thorax  ami  primaries  a bright  glistenins 
lemon-yellow;  transverse  lines  of  primaries  hrown.  Basal  half  line  faint.  T.  a. 
line  well  removed  from  base,  with  a long  outward  angle  on  median  vein.  T.  p. 
line  acutely  angulate  outwardly,  the  spur  reaching  the  outer  margin  below  the 
apex.  S.  t.  line  also  with  an  outward  angle,  reaching  the  outer  margin  at  the 
same  point  with  the  t.  p.  line.  A small,  geminate  black  dot  on  costa,  just  before 
the  apex.  Between  the  point  at  which  the  angulation  of  the  outer  lines  touches 
the  margin  and  the  anal  angle,  a metallic  coppery  brown  shade  fills  the  space 
beyond  the  s.  t.  line.  Secondaries  pale  yellow,  ocherous,  more  whitish  basally. 
Beneath  yellow,  powdery,  immaculate,  the  secondaries  whitish  towards  inner 
margin.  Expands  1.40  inches;  35  mm. 

Hab. — Southern  Texas 

A single  sjtecimen  from  Mr.  Neumoegen’s  collection  is  before  me. 
It  has  much  the  same  color  as  buxea,  but  is  larger,  the  course  of  the 
lines  is  different,  and  there  is  the  cojipery  brown  outer  shade,  -which 
is  distinctive.  In  maculatioii  and  color  this  is  remarkably  close  to 
Guenee’s  Xanthodes  traiisversa  from  India,  so  close,  indeed,  that  had 
the  species  been  described  from  America  I had  considered  the  differ- 
ences within  the  range  of  specific  variation. 

Lys;raiithcecia  pariiieliana  Hy.  Edw. 

To  the  kindness  of  Mr.  Schoenborn  I owe  a sight  of  the  type.  It 
has  the  wing  form,  and  exactly  the  macnlatioii  of  nundina,  but  the 
ground  is  ocher  yellowish,  the  lines  white,  and  the  dark  markings

are  umber-brown,  with  an  olivaceous  slieen.  The  secondaries  are 
yellowish  at  base,  with  a broad  blackish  outer  margin.  The  tibial 
armature  consists  of  two  long  inner  and  three  shorter  outer  claws  or 
spines,  referring  to  constricta,  brevis,  errans  and  the  small  species  near 
the  foot  of  my  series,  with  which  this  form  has  nothing  in  common. 
It  is  undoubtedly  a good  and  quite  remarkable  species.

1884  Papilio  iv,  124. 

This  species  is  now  represented  in  the  Museum  collection  by  sev- 
eral specimens.  It  was  not  known  to  me  in  1883,  when  I published 
my  revision  of  the  Heliothini,  but  was  found  in  the  Belfrage  material 
which  came  to  the  Museum.  Mr.  Edwards  kindly  gave  me  a speci- 
men of  his  species,  now  also  in  the  Museum,  and  this  enabled  me  to 
make  the  above  synonymical  reference. 

The  sjiecies  has  the  structural  features  of  Schinia  lynx  and  its  type 
of  maculation,  replacing  the  yellow  by  bright  red  throughout. 

]\Ir.  Edwards’  species  is  not  referred  to  in  Mr.  Giote’s  list  of  1890, 
nor,  indeed,  any  of  the  following  species:  Anthcecia  petnlcms  Edw., 
Tamila  arefacta  Edw.,  Acopa  pacijica  Edw.,  Melicleptria  septentrional  is 
Edw.,  Heliothis  siiavis  Edw., — all  described  in  1884! 

]\Ir.  Grote  seems  to  think,  as  he  said  of  Boisduval  about  twenty 
years  ago,  that  no  work  has  been  done  since  his  last  descriptive 
papers. 

^icliiiiia  sexplagirtts*  m sp. — Head  and  thorax  dark  olivaceous  greenish 
gray.  Primaries  pale,  powdery  greenish  gray,  basal  space  and  costal  and  mar- 
ginal patches  in  s t.  space  dark,  olivaceous,  of  the  same  tint  as  thorax.  Basal 
line  marked  on  costa  only.  T.  a.  line  pale,  well  marked,  forming  a very  even 
and  regular  outcurve.  T.  p.  line  even,  i)ale,  narrower  than  t.  a.  line,  evenlj’ 
outcurved  over  the  cell,  and  as  evenly  though  less  prominently  incurved  below. 
S.  t.  line  pale,  not  so  well  mai-ked  as  the  median  lines,  a little  irregular  and 
holding  a middle  between  t.  p.  line  and  outer  margin  in  course.  A pale  line  at 
base  of  fringes,  which  are  concolorous,  interlined  with  pale.  The  s.  t.  space  is 
slightly  dai’Ker  than  ground  color,  except  on  costa  and  internal  margin,  where  it 
is  of  the  same  color  as  the  basal  sjiace.  A vague,  dusky,  median  shade  over  the 
reniform,  bringing  this  spot  into  view  as  an  u])right  dusky  patch  not  definitely 
margined.  There  is  a vague  suggestion  of  an  orbicular.  Secondaries  white, 
with  a blackish  discal  lunule  and  outer  margin,  the  latter  with  a white  central 
shade,  more  prominent  toward  anal  angle;  fringes  white.  Beneath  whitish, 
tinged  with  faint  olivaceous,  both  wings  with  a narrow  outer  line;  primaries 
with  black,  contrasting  reniform  and  orbicular.  Expands  1.04  inches;  26  mm.

The  front  is  globose,  bulging;  fore  tibije  with  a long  inner  and 
two  shorter  outer  s])inules.  This  species  is  allied  to  hiundnlata  in 
general  appearance,  but  differs  widely  in  details.  The  wdiite  secon- 
daries, the  contrasting  shades  of  primaries,  and  conspicuous  ordinary 
spots  of  the  under  side,  are  all  good  distinctive  features.  A single 
good  male  is  in  the  collection  U.  S.  Nat.  Museum,  from  INIr.  BiTice, 
and  this  is  the  type.

either  evenly  parallel  to  outer  margin,  or  indented  opposite  the  cell,  .sometimes 
almost  cutting  the  s.  t,  space.  Terminal  space  slightly  darker  than  ground  color. 
A series  of  small,  terminal,  blackish  dots.  Fringes  concolorous,  with  dusky 
terminal  dots.  A deeper  shade  of  ground  color  through  outer  part  of  median 
space,  narrowed  to  a line  at  the  hind  margin.  Reniform  large,  dusky,  with 
blackish  lateral  margins,  not  completely  defined;  no  orbicular.  Secondaries 
whitish,  with  dusky  outer  margin,  interrupted  by  an  irregular  whitish  shade 
behind  middle,  a moderate  discal  s]iot  and  white  fringes.  Beneath  whitish,  with 
maculation  of  upper  side  incompletely  reproduced,  powdery;  primaries  with 
orbicular  and  reniform  usually  very  distinct.  Expands  1.00— 1.20  inches ; 25 — 
.30  mm.

[ have  seen  quite  a number  of  this  s[)ecies,  and  four  g(tod  speci- 
mens are  in  tbe  (Museum  collection.  It  is  larger  tban  crenilinea, 
tbougb  similarly  marked,  but  tbe  armature  of  tbe  tibise  allies  it  to 
.•separata.  From  all  tbe  forms  of  that  species  tbe  cbaracter  of  tbe 
median  lines  will  serve  to  separate  it,  tbe  color  sometimes  being  very 
similar. 

Tbe  species  is  named  after  its  collector  wbo  bas  found  more  new 
species  tban  any  other  recent  field  worker  in  Lepidoptera,  and  wbo 
is  as  liberal  as  be  is  skillful  in  preparing  bis  specimens. 

Schiiiia  n.  sp. — Head,  thorax  and  primaries  a vague  reddish  gray, 

of  a faded,  washed-out  hue,  the  maculation  on  primaries  scarcely  traceable. 
Basal  and  s.  t.  spaces  a shade  deeper  in  color,  and  thus  rendered  visible.  T.  a. 
line  narrow,  thread-like,  paler,  outwardly  augulated  in  the  submedian  interspace. 
T.  p.  line  narrow,  crenulate,  evenly  curved  to  thesubmedian  interspace  and  there 
somewhat  abruptly  incurved.  S.  t.  line  faintly  marked  only  at  costa,  else  not 
traceable.  Reniform  an  indefinite,  vague,  dusky  blotch.  Secondaries  whitish,

Hah. — Colorado  (Bruce). 

Three  specimens,  male  and  female,  from  the  collection  U.  S.  Nat. 
Museum,  others  in  INIr.  Neumoegen’s  collection.  The  species  is 
allied  to  saturata  in  tibial  armature,  and  somewhat  also  in  habitus, 
but  the  course  of  the  t.  a.  line  is  entirely  dilferent,  and  the  fade<l, 
washed-out  appearance  is  peculiar  to  this  species. 

^(cliiiiia  ocUreifsiscia  n.  sp. — Head  and  thorax  overlaid  by  a thick  layer 
of  ocherous  .scales  on  a white  base,  the  white  appearing  at  tips  of  collar,  patagise 
and  thoracic  tuftiugs  generally.  Primaries  white,  banded  with  brownish  ocher 
or  tan  color.  A well  defined,  moderately  broad,  even  band  at  basal  fourth,  the 
outer  margin  at  about  the  place  usually  occupied  by  the  t.  a.  line.  A broader, 
less  definite  median  fascia,  the  color  less  intense,  the  band  broadest  at  its  middle, 
narrower  at  inner  than  at  costal  margin.  A moderately  broad  fascia  of  even 
width,  its  course  slightly  sinuate,  occupies  w’hat  is  ordinarily  the  s.  t.  space.  A 
half  band  starts  from  costa  at  apex  and  tapers  out  at  about  the  middle  of  outer 
margin.  A darker  line  at  base  of  tbe  white  fringes.  Claviform  and  orbicular 
wanting.  Reniform  consists  of  a brown  lunule  at  end  of  cell,  followed  by  a 
small  spot  of  the  same  color  just  beyond.  Secondaries  white,  shading  to  ocher- 
ous outwardly.  Beneath  yellowish  white,  jirimaries  with  a suhmarginal  deeper 
fascia,  leaving  marginal  space  somewhat  contrasting  white.  Expands  .92  inch.; 
23  mm.

Two  specimens  in  the  National  Museum  collection  (through  C.  V. 
Riley),  neither  of  them  in  good  condition,  hut  together  making  a 
very  perfect  whole.  The  species  has  the  ground  color  of  cuniatilis, 
and  the  ocherous  fascite  of  chrysellus,  hut  is  utterly  unlike  either  in 
type  of  maculation.  The  front  is  protuberant,  bulging,  but  not 
rough,  and  the  armature  of  the  fore  tibiie  is  comparatively  weak 
and  consists  of  a long  inner  spine,  and  a series  of  shorter  outer  spines, 
much  as  in  cumatilis,  but  less  claw  like. 

One  specimen  has  a red  ink  number  181,  which  indicates  a biolog- 
ical note  on  the  species,  in  Dr.  Riley’s  posse.ssion. 

Kcliiiiia  uni  macula  n.  sp. — Head,  thorax  and  primaries  white,  markings 
of  the  latter  of  a faint  olivaceous  clay  yellow.  Primaries  with  a broad,  curved, 
sub-basal  band,  the  outer  margin  limiting  the  t.  a.  line,  which  is  followed  by  a 
few  .scales  of  the  same  color  as  the  hand,  indicating  its  outer  margin.  Outer 
portion  of  median  space  and  all  of  s.  t.  space  of  the  same  faint  olivaceous  tint, 
through  which  the  white  t.  p.  line  is  evident,  starting  in  a broad  costal  patch, 
narrowing  to  a mere  line  in  its  outward  curve  over  the  cell  and  becoming  more

obvious  on  the  incurve  and  at  the  inner  niarfiiji.  S.  t.  line  marked  only  hy  the 
difl'erence  in  shade  between  terminal  and  s.  t.  space.  This  difference  is  very 
strongly  marked  at  the  costa,  then  the  s.  t.  space  is  almost  divided  by  the  white, 
and  thence  the  dark  color  again  widens  with  an  outward  curve  the  division  not 
sharjily  marked.  A row  of  black  terminal  dots.  Base  of  fringes  olivaceous. 
Eeniform  upright,  dark,  constricted  inferiorly,  black  marked,  and  more  dilated 
than  superiorly  ; no  trace  of  orbicular.  Secondaries  white,  with  a dusky  discal 
•spot  and  indefinite  outer  border,  in  which  is  an  ovate  white  spot.  Beneath  white, 
with  the  maculation  of  the  upper  side  faintly  reproduced.  Expands  1.04  inches; 
26  mm. 

Hab. — Colorado  (Bruce). 

Tills  is  a close  ally  of  <S'.  vanella,  which  it  resembles  completely  in 
habitus  and  structure.  It  differs  obviously  in  the  entire  lack  of  the 
orbicular  and  claviform  in  the  much  smaller  reniform  and  in  a gen- 
eral softness  of  tint  and  maculation  not  noted  in  its  eastern  congener. 
The  type  is  from  Mr.  Neumoegen’s  collection,  and  there  are  three 
handsome  examples  in  the  collection  U.  S.  Nat.  INIuseum,  all  of  Mr. 
Bruce’s  collecting. 

biciispida  n.  sp. — Head,  thorax  and  primaries  luteous.  Prima- 
ries with  maculation  darker,  more  olivaceous,  and  with  an  admixture  of  black i.sh 
scales.  The  transverse  lines  are  all  of  the  palest  shade  of  the  ground  color,  and 
defined  by  the  difference  in  shade  between  tbe  adjoining  spaces.  T.  a.  line  with 
a long  outward  cusp  on  the  median  vein,  and  a deep  incurve  below  the  internal 
vein.  Basal  space  dark,  with  a pale  cusp  on  the  costa,  and  with  a strong  admix- 
ture of  black  scales  along  inner  margin,  tbe  internal  vein  pale.  S.  t.  line  regu- 
larly bisinuate,  even,  oblique,  well  defined  tbroughout.  S.  t.  space  quite  strongly 
speckled  with  black  scales,  especially  along  the  outer  margin  defining  the  s.  t. 
line.  This  latter  is  deeply  and  suddenly  incurved  opposite  the  cell,  then  ap- 
proaches quite  close  to  the  outer  margin,  again  indented  nearly  opposite  the  anal 
angle.  A row  of  small  blackish  terminal  spots,  from  which  proceed  blackish 
shades  cutting  the  fringes.  Orbicular  wanting.  Reniform  moderate,  blackish, 
quite  indefinite;  median  s])ace  crossed  by  a diffuse  dusky  shade,  faint  through 
the  centre,  but  spreading  out  and  occupying  nearly  the  entire  width  of  the  me- 
dian space  inferiorly.  Secondaries  black,  with  a broad  yellow  median  band, 
divided  by  a large  black  discal  spot;  fringes  yellow.  Beneath,  primaries  pale 
yellow,  with  a broad  basal  shade,  a large  discal  spot,  and  a broad  subterminal 
baud  black  ; secondaries  white,  with  an  incomplete  outer  band  and  discal  lunule 
black.  Expands  .96  inch. ; 24  mm. 

Hub. — Southern  Texas. 

The  anterior  tibia  has  two  stout  inner  and  five  stout  outer  claws, 
and  it  is  therefore  related  to  pucku7'dii,  morhia  and  nobills.  From 
all  of  these  it  difiers  in  the  course  of  the  transverse  lines,  and  the 
more  decided  contrasts  in  maculation.  A single  specimen  from  Mr. 
Neumoegen’s  collection  is  before  me.

Kchiilia  eonc*iiiiia  u.  sp. — Head,  thorax  and  ground  color  of  luiniaries  a 
rather  deep  luteons,  with  an  olivaceous  tint.  Primaries  maculate  with  a rather 
deep,  almost  chocolate-brown.  Basal  space  brown,  deepest  at  the  t.  a.  line,  and 
merging  into  the  ground  color  at  the  extreme  base.  T.  a.  line  white,  prominent, 
outwardly  oblique  in  two  curves  to  median  vein,  then  inwardly  oblique  in  two 
further  curves  to  hind  mai-gin.  T.  p.  line  white,  rather  strongly  and  quite 
evenly  bisinuate,  well  marked,  excejit  over  the  cell,  where  it  is  interru]>ted  and 
imnctiform;  outwardly  it  is  marked  with  black  scales.  S.  t.  space  darkest  at 
1.  p.  line,  lightening  somewhat  to  s.  t.  line,  which  is  very  irregular  and  marked 
only  by  the  contrast  between  the  dark  s.  t.  space  and  the  terminal  space,  which 
is  of  the  ground  color.  Fringes  of  ground  color  with  a series  of  darker  terminal 
dots.  Orbicular  wanting ; reniform  large,  dark,  somewhat  indefinite,  obscured 
by  a dusky  shade,  which  crosses  the  median  space  and  merges  into  the  ground 
color  at  either  margin.  Secondaries  obscurely  tawny  at  base,  becoming  black  at 
outer  margin.  Fringes  pale  luteons,  almost  dirty  white.  Beneath  tawny,  prima- 
ries with  disc  black,  sending  up  an  ante-apical  si>ot  of  same  color ; a black  discal 
spot.  Secondaries  with  a large  discal  spot  and  a deejier,  brownish  black  outer 
margin.  Expands  .9(1  inch. ; 24  mm. 

Hdb. — Southern  Texas. 

This  s])ecies  has  two  inner  and  three  outer  claws  to  the  fore-tibia 
and  is  most  nearl}^  related  to  brevis  Grt.  The  contrasting  white 
lines,  the  olivaceous  luteons  ground  color  and  the  course  of  the  lines 
are  difierent ; brevis  seems  not  to  have  the  broad  median  shade.  A 
single  specimen  from  Mr.  Neumoegen. 

Scliiiiia  digitalis  n.  sp. — Hesd,  thorax  and  primaries  a itowdery  luteons 
gray.  Primaries  with  basal  and  s.  t.  space  darker,  with  an  admixture  of  blackish 
scales;  median  lines  narrow,  pale.  T.  a.  line  evenly  oulcurved,  the  curve  greatest 
in  the  cell.  T.  p.  line  very  narrow,  and  but  very  little  sinuate,  almost  rigidly 
oblique.  S.  t.  line  marked  by  the  diflereuce  in  shade  between  s.  t.  and  terminal 
space,  strictly  parallel  with  the  outer  margin.  Fringes  dusky.  Secondaries  a 
pale  yellowish  gray  with  a more  blacki.sh  outer  margin  and  very  faint  discal 
blotch  Beneath,  primaries  dirty  gray,  with  a faint  reproduction  of  the  outer 
lines  of  upper  side,  and  a dusky  discal  spot;  secondaries  much  as  above.  Ex- 
pands 1.20  inch. ; 30  mm. 

Hab. — Dallas,  Texas. 

This  species  has  heavy  inner  and  four  heavy  outer  claws  to  the 
anterior  tibia,  and  is  therefore  related  to  thoreaui  and  rivulosa,  from 
which  it  differs  radically  in  the  coloration.  It  is  the  only  species 
with  the  heavy  armature  which  has  this  luteons  gray,  almost  greenish 
tinge.  It  hears  a deceptive  resemblance  to  gracilenta,  and  the  mark- 
ings, indeed,  are  almost  exactly  like  it. 

A single  specimen  only  at  hand,  hut  I feel  (juite  certain  that  it  is 
in  other  collections  as  a faded  gracilenta.

Sohinia  biiiiKliilata  n.  sp. — Head  white,  with  a faint  olivaceous  tinge, 
much  more  marked  on  the  thorax ; abdomen  fuscous.  Primaries  a faintly  green 
luteous  or  olivaceous,  the  terminal  space  slightly  paler,  else  almost  uniform  in 
tint.  The  median  lines  are  very  distinct,  broad  and  white;  the  t.  a.  outwardly 
curved  and  inwardly  marked  by  a few  black  scales ; t.  p.  S-shaped,  or  strongly 
hisinuate,  outwardly  relieved  by  a few  black  scales.  Fringes  whitish,  uniform 
in  color.  Secondaries  faintly  olivaceous,  pale,  with  an  indefinite  dark  outer 
hand,  and  a dusky  discal  spot.  Beneath,  primaries  silver-gray,  with  the  costal 
and  outer  margin  narrowly  yellowish.  Secondaries  white,  with  a faint  discal 
spot.  Expands  .92  inch. ; 23  mm. 

Hab. — Colorado  (Bruce). 

This  haudsoiiie  and  strongly  marked  species  is  allied  in  structural 
characters  to  trifascia  or  cumatiiis,  and  is  very  distinct  from  anything 
I have  seen. 

The  single  specimen  before  me  is  from  Mr.  Nenmoegen’s  collec- 
tion, and  I do  not  remember  having  had  others. 

Scliiiiia  simple.^  n.  sp. — Head,  thorax  and  primaries  of  a glistening,  pale 
green  color;  immaculate.  Secondaries  a very  faint  ocher  yellow,  with  an  in- 
definite dusky  discal  spot,  and  a dusky  outer  margin,  not  extending  more  than 
two-thirds  from  apex  to  anal  angle.  Beneath,  a glistening,  pale  yellowish  white, 
with  an  indefinite  blackish  discal  spot  on  all  wings.  Expands  1.20 — 1.28  inch. ; 
30 — 32  ram. 

Hab. — Colorado. 

This  species  has  a single  long  inner  and  three  feebler  outer,  claw- 
like  spines  to  the  fore  tibia,  and  it  belongs  to  the  series  with  trifascia 
and  gracilenta,  from  all  of  which  it  differs  in  the  immaculate  prima- 
ries. The  specimens  were  collected  by  Mr.  Bruce,  and  are  distributed 
in  a number  of  collections,  including  that  of  the  U.  8.  Nat.  Mus. 
The  specimen  before  me  is  marked  “ Denver,  Light,  July  21,  1887.” 

In  the  two  specimens  in  the  Museum  collection,  one,  marked 
“ Foot-hills,  Colo.”  has  entirely  immaculate  secondaries;  the  other 
specimen  is  much  deeper  in  color  throughout,  and  the  marginal  black 
band  is  much  more  distinct,  and  is  complete,  extending  also  along 
the  costa. 

Scliiiiia  ci'Oiiilinea.  u.  sp.— Head  and  thorax  yellowish  white,  the  thorax 
with  an  admixture  of  ouherous  scales.  Primaries  whitish,  with  a strong  ad 
mixture  of  ocherous,  the  maculation  with  a brown  admixture  to  the  ocher.  A 
broad  sub-basal,  dusky  band,  outwardly  limited  by  the  white  t.  a.  line,  which  is 
outwardly  curved  and  irregularly  denticulate  on  the  veins,  the  widest  outcurve 
in  the  submedian  interspace.  Inwardly  this  line  is  marked  by  a few  black  scales, 
outwardly  it  is  indefinite.  T.  p.  line  white,  outwardly  defined  by  black  scales, 
crenate,  with  distinct  outward  spurs  on  the  veins,  its  general  course  feebly  bi- 
sinuate.  S.  t.  line  marked  by  the  difierence  between  the  brownish  s.  t.  space

and  the  even  faintly  oclieroiis  white  of  the  terminal  space.  S.  t.  space  strongly 
constricted  opposite  cell,  less  so  in  the  s.  in.  interspace.  A row  of  very  faint 
terminal  dots.  An  upright  dusky  median  shade,  fading  gradually  to  the  ground 
color  in  each  direction.  Reniform  an  indefinite,  upright,  dusky  line.  Seconda- 
ries pale  with  a faint  reddish  tint  deepening  to  a coppery  red  outer  border.  Be- 
neath, quite  uniform  co]>pery  red,  the  secondaries  paler  basally,  primaries  im- 
maculate. Expands  .92  inch.  ;23  mm. 

Hab. — Southern  Texas. 

This,  in  its  structural  characters,  resembles  spinosce,  and  in  appear- 
ance is  allied  to  sejicirata  and  saturata,  the  latter  of  which  it  resem- 
bles in  the  crenulate  median  lines  and  general  tendency  of  maculation. 
I presume  this  would  be  a Eupanychh  according  to  Mr.  Grote,  if  its 
relation  to  spinosce  be  a generic  character. 

Heliophaiia  obliquata  n.  sp. — Head  and  thorax  a rather  deep  clay- 
yellow,  with  an  olivaceous  tinge,  alinost  tawny;  abdomen  blackish.  Primaries 
above  an  olivaceous,  dark  luteous,  marked  with  a somewhat  rusty  red-brown. 
There  is  no  distinct  t.  a.  line.  An  oblique  brown  shade  band  extends  from  the 
inner  margin  near  base  to  the  end  of  the  median  cell,  joining  the  upright  some- 
what indefinite  reniform.  From  this  band  a spur  of  the  same  color  is  sent  to 
the  base  along  the  internal  vein,  and  another  along  the  median  vein.  A narrow 
streak  runs  also  through  the  cell  to  the  reniform.  T.  p.  line  concolorous,  even, 
entirely  parallel  with  the  outer  margin,  marked  by  a very  narrow,  indefinite. 
l)recediug  brown  line,  and  followed  and  defined  by  the  brown  s.  t.  space.  S.  t. 
space  uniformly  brown,  marking  the  s.  t.  line  by  the  contrast  between  it  and  the 
terminal  space.  This  line  of  contrast  is  irregularly  bisinuate.  A brown  terminal 
line  at  the  base  of  the  concolorous  fringes.  Secondaries  black,  mingled  with  the 
tawny  yellow  basally,  the  fringes  tawny.  Beneath,  primaries  black,  costal  and 
outer  margin  tawny,  the  former  allowing  part  of  a black  discal  mark  to  be  visible. 
Secondaries  with  co.stal  third  and  centre  tawny,  else  black.  A large  black  discal 
spot.  Expands  .75  inch. ; 19  mm. 

Hab. — Texas  (Neumoegeii). 

I have  had  several  examples  of  this  little  species  for  determinatiou, 
some  of  them  I thiuk  from  Colorado,  but  have  not  named  it  any- 
where. The  characters  agree  well  with  those  of  the  genus  as  given 
by  me  (Trans.  Am.  Ent.  Soc.  x,  240).  It  is  not  impossible  that  this 
is  an  extreme  variety  of  Mr.  Grote’s  species,  but  both  upper  and 
under  side  differ  from  the  description  and  from  the  specimens  I have 
seen.  In  mitis  the  ground  color  is  dark,  while  in  the  jiresent  species 
it  is  pale ; but  this  reversal  does  not  necessarily  indicate  absolute 
difference. 

Ileliopliaiia  amaryllis  n.  sp. — Head,  thorax  and  abdomen  black,  with 
fine,  thin,  loose,  divergent,  pale  yellowish  vestiture.  Primaries  a dirty  grayish 
brown,  median  sjiace  a dirty  yellowish  white.  Basal  line  distinct,  whitish,  mar- 
gined by  black.  T.  a.  line  whitish,  i)receded  by  a black,  and  followed  by  a dark

slight  convexity  in  the  cell,  the  round  orbicular  rests  on  the  line.  T.  p.  line 
whitish,  even,  widely  outcurved  over  the  cell  and  incurved  beneath:  defined 
outwardly  l>y  the  dark  ground  color,  inwardly  by  a narrow  gray-brown  line. 
The  reniform  is  large,  black,  filling  the  entire  width  of  the  cell  and  resting  on 
the  incurve  of  the  t.  p.  line.  A narrow  dusky  shade  from  the  reniform  to  hind 
margin  close  to  t.  p line.  Beyond  the  t.  p.  line  the  wing  is  uniform  in  color, 
somewhat  white  marked  on  the  veins  and  crossed  by  the  narrow  whitish  s.  t. 
line,  which  is  twice  outcurved  and  with  three  acute  inward  teeth.  Secondaries 
black,  with  a broad  whitish  hand,  almost  divided  by  the  large  black  discal  spot, 
Beneath,  primaries  white,  with  a broad,  irregular,  black  outer  border,  a broad 
black  basal  dash,  and  a large  black  reniform.  orbicular  and  subapical  spot.  Sec-

short,  broad,  costa  somewhat  de|)ressed,  making  the  apices  prominent. 

This  genus  resembles  Pseudotamila  in  structure,  save  that  the  tibiie 
are  not  spinose,  and  the  primaries  have  the  costa  de|)ressed.  Its 
characters  are  also  like  F.^eudacontla,  save  that  the  eyes  are  narrow, 
ovate.  The  genus  is  recognizable,  and  unlike  any  other  of  our 
Heliothid  foi'ins  known  to  me. 

Ktylopoilsi  eeplialica  !i.  sp. — Head,  thorax  and  abdomen  deep  piir])li.^h 
blaek.  Primaries  purplish  hlack  to  t.  p.  line,  then  an  irregular  white  shade 
fading  into  the  black  ground  color  beyond.  The  macnlation  on  the  inirjtlish 
ground  is  picked  out  by  deep  black  scales.  Basal  line  single,  complete.  T.  a. 
line  .single,  fine,  upright  or  slightly  oblique,  very  regularly  tridentate.  T.  p.  line 
single,  outwardly  oblique  from  costa  over  reniform.  then  very  deeply  indrawn.

UHTrowine;  the  median  space  by  fully  one-half  below  vein  2.  This  line  is  em- 
phasized by  the  pure  white  following  shade,  which  is  broadest  in  the  suhmedian 
interspace,  white  scales — seeming  bluish  on  the  back  ground — extending  through 
the  subterrainal  space  and  on  costa,  vaguely  indicating  the  s.  t.  line.  An  inter- 
rupted black  terminal  line.  Claviform  apparently  wanting.  Orbicular  moderate, 
concolorous,  round,  black-ringed.  Eeniform  incomplete,  apparently  only  the 
inner  margin  defined,  the  outer  merged  in  the  white  shade.  Secondaries  black, 
with  white  fringes.  Beneath  black,  primaries  with  an  interrupted  white  baud. 
Expands  .68 — .72  inches;  17 — 13  mm. 

Hab. — California. 

Two  specimens  ( 9 ) are  in  the  National  Mnsenm,  one  from  my 
old  collection,  the  other  “ through  C.  V.  Riley,  1888,"  collected  by 
Coquillet.  The  latter  is  perfect  so  far  as  maculation  goes,  but  the 
legs  are  deficient.  The  former  is  somewhat  rubbed,  and  has  no  legs 
at  all. 

This  is  a strongly  marked  form  which  there  should  not  be  any 
difficulty  in  recognizing. 

There  is  a single  male  specimen  from  my  collection  in  the  Museum, 
also  from  California,  which  is  congeneric,  but  which  is  almost  too 
poor  to  serve  as  a ty]>e.  The  [)rimaries  above  have  been  rubbed 
almost  bare  of  scales,  and  no  maculation  is  traceable.  The  secon- 
daries are  black.  Beneath,  the  primaries  are  carmine-red,  the  secon- 
daries black.  If  this  is  in  any  collection,  I should  like  to  get  good 
specimens. 

l*seii<lacoiitia  cru»itaria  Morr. 

A specimen  of  what  1 take  to  be  a form  of  this  species  is  in  the 
National  Museum  collection,  from  Mr.  Bruce.  It  is  like  the  type  in 
)>attern  of  maculation,  but  the  black  is  replaced  by  an  ocherous 
brown  on  primaries,  and  the  median  white  band  of  secondaries 
broadens  and  becoming  inwardly  diffuse,  lightens  the  base.  The 
type  is  from  Nebraska,  and  I have  seen  no  other  specimens.  It  may 
be  we  have  to  do  here  with  another  species,  but  without  more  ma- 
terial I prefer  to  leave  it  as  a geographical  race  or  form. 

Mefopoiiia  macula  sp.  nov. — Head,  thorax  and  primaries  orange-yel- 
low. Head  and  collar  with  an  admixture  of  brown.  Primaries  with  a purplish 
blotch  filling  the  base  of  discal  cell,  and  narrowly  connected  along  the  median 
vein  with  a darker,  irregular  blotch,  whose  outer  margin  is  about  where  the  t. 
p.  line  should  be  were  it  present;  a small,  irregular  spot,  marks  the  location  of 
the  accessory  cell.  The  inception  of  the  s.  t.  line  is  marked  by  a small,  some- 
what ferruginous  preceding  patch,  and  below  that  by  a series  of  four  or  five 
irregularly  separated  venular  dots.  Two  dots  below  the  basal  purple  blotch  mark 
the  t.  a.  line.  Fringes  cut  with  purplish.  Ordinary  spots  entirely  obsolete.

Oltviously  distinct,  from  the  described  species  by  the  black  secon- 
daries with  contrasting  yellow  fringes.  The  clypeal  structure  is  a 
cup-shaped  depression,  from  which  rises  a cylindrical  projection  also 
cupped  at  tip.  Specimens  taken  by  Mr.  Meeske  are  in  the  collections 
of  Neumoegen  and  Hulst. 

ACJROTirHII.A  Grt. 

This  genus  was  proposed  by  Mr.  Grote  (Ann.  Lyc.  1875,  xi,  107) 
for  Mr.  Morrison’s  Agrotis  montuna,  and  the  genus  is,  in  my  opinion, 
a good  one,  diflering  from  Agrotis  in  the  narrow,  reniform  eyes,  the 
retracted  head  and  anartijorm  habitus.  To  this  must  come  FacJmobia 
alaske  Grt.,  of  which  there  is  a specimen  in  the  U.  S.  Museum, 
easily  recognizable  by  the  discolorous  claviform. 

Among  the  species  never  recognized  by  Mr.  Grote  is  Moeschler’s 
Agrotis  stanclingeri  (Wien.  Eut.  Monatsch.  vi,  132,  pi.  1,  fig.  4,  May, 
1862).  To  the  courtesy  of  Mr.  Moeschler  I owed  a chance  to  ex- 
amine his  type,  and  found  it  to  be  in  all  respects  like  Morrison  s 
species.  The  figure  is  accurate,  and  there  is  no  doubt  at  all  that 
staudingeri  must  replace  montana  in  the  lists. 

INIorrison  described  his  species  from  Colorado,  July  22d  to  August 
12th,  12,000  feet.  Afterward  the  species  was  received  from  Mt. 
Washington,  and  Labrador  is  now  added  to  the  distribution.  In 
the  collections  made  by  Mr.  Bruce  there  is  a species  which  I at  first 
considered  the  same  as  that  described  by  Morrison,  but  which  offers 
a number  of  constant  points  of  difference,  which  I think  justify  a 
new  species  fully  congeneric  with  staudingeri. 

Agrotipliila.  colora*lo  n.  sp. — Ground  color  of  head,  thorax  and  prima- 
ries an  olivaceous  luteous,  or  ocherous  brown,  the  variation  being  quite  consid- 
erable. Front  with  a strong  admixture  of  white  hair,  forming  a white  margin 
to  the  eyes.  Collar  black  centred  with  a whitish  basal  and  terminal  margin. 
Patagife  white  margined.  Abdomen  blackish,  wdth  fine  w-hite  or  pale  yellow 
hair.  Basal  line  black,  single,  outwardly  margined  with  white.  A curved  black 
streak  crossing  the  basal  space  on  the  internal  vein,  margined  above  with  white, 
and  this  with  the  white  inner  margin  to  the  t.  a.  line  makes  a quadrate  space  at 
base,  the  angles  all  extended.  T.  a.  line  incurved,  the  lower  curve  long  and 
reaching  nearly  to  the  middle  of  the  inner  margin.  T.  p.  line  with  an  even 
outcurve,  nearly  parallel  with  outer  margin ; inner  line  composed  of  connected, 
black  lunules,  outer  Hue  a broad  whitish  shade.  S.  t.  line  white,  ditluse,  pre-

ceded  by  a series  of  more  or  less  confluent  sagittate  l)lack  spots,  broadly  inter- 
ruiited  sut)apically.  A dusky  line  at  base  of  fringes.  .\ll  the  veins  white  marked  ; 
a mere  trace  of  claviform.  Orl)icular  large,  irregularly  ov'al,  black  margined, 
inwardly  white  ringed,  centre  pale.  Eeniform  large,  kidney-shaped,  narrowly 
black  ringed,  inwardly  white  margined,  centre  pale.  The  space  between  these 
ordinary  spots  is  blackish,  and  there  is  a black  spur  from  reniform  to  t.  p.  line. 
Secondaries  blackish  fuscous  to  blackish,  with  white  fringes.  Beneath  whitish, 
both  wings  with  narrow  dusky  margins  and  linear  discal  spots.  Breast  blackish, 
legs  with  fine,  thin,  white  hair.  Antennte  of  male  with  whitish  cilise.  Expands 
1.16 — 1.24  inches:  29—31  mm. 

Hah. — Colorado,  Bruce. 

Both  sexes  of  this  species  are  before  me  from  i\Ir.  Bruce’s  collec- 
tions. There  is  considerable  difference  in  the  general  appearance  of 
the  sexes,  though  not  in  details  of  maculation.  The  male  is  the 
smaller,  and  is  sordid,  more  pale  and  less  definitely  marked  ; in  the 
female  the  ground  color  is  deeper,  richer,  and  the  white  contrasts 
very  much  more  distinctly. 

Comjiared  with  staudingeri,  this  species  is  larger,  the  claviform  is 
barely  marked,  and  the  orbicular  is  different  in  shape,  large  and 
irregularly  oval  in  this  species,  small  and  round  in  stemdingeri.  The 
species  is  in  Mr.  Neumoegen’s  collection,  and  I have  seen  others  from 
Mr.  Bruce.  A good  pair  in  the  National  Museum  collection  among 
others. 

.\grotipliila  rigida  n.  sp. — Head,  thorax  and  primaries  dull  fuscous 
brown,  with  a yellowish  admixture  in  the  hasal  and  s.  t.  spaces.  Front  with 
pale  scales  intermixed.  Basal  line  evident,  black,  followed  by  a white  shade. 
T.  a.  line  rigid,  slightly  oblique  outwardly,  white  inwardly,  margined  outwardly 
by  black,  which  is  a little  extended  on  the  veins.  T.  p.  line  outcurved  over 
cell,  thence  nearly  parallel  with  outer  margin  ; inner  line  black,  a little  out- 
wardly denticulate  on  the  veins,  followed  by  a rather  diffuse  whitish  shade. 
The  veins  are  pale  marked  through  the  s.  t.  space,  and  aid  in  defining  the  series 
of  dusky,  sagittate  spots  before  the  s.  t.  line.  This  latter  is  whitish  yellow, 
rather  broad,  distinct,  very  even,  a little  outwardly  bent  only  on  veins  3 and  4, 
a blackish,  interrupted  terminal  line.  Claviform  rather  obscure,  incompletely 
outlined,  concolorous.  followed  by  a distinct  yellowish  shade,  which  extends  to 
the  t.  p.  line.  Orbicular  small,  oval,  slightly  oblique,  black  margined,  pale 
ringed,  and  wifli  concolorous  centre.  Eeniform  moderate,  kidney-shaped,  pale 
ringed,  with  narrow  black  margin  and  concolorous  centre.  Secondaries  smoky 
fuscous,  somewhat  paler  basally,  with  a dusky  discal  lunule.  Beneath  whitish, 
powdery,  with  a common,  broad,  blackish,  e.xtra  median  band  : a discal  spot  on 
all  wings;  primaries  with  a faint,  dusky,  submarginal  band  and  secondaries, 
with  a dusky  outer  margin.  Exi)ands  1 inch  ; 2.5  mm.

A single  specimen  of  this  species,  from  ]\Ir.  Neumoegen’s  collection, 
is  before  me,  and  is  in  good  condition.

This  is  one  of  the  most  interesting  species  I have  studied,  and  will 
not  remain  in  the  genus  in  which  I have  placed  it  despite  its  strong 
habital  resemblance  to  both  standingeri  and  Colorado.  The  eyes, 
while  narrowed,  are  scarcely  as  constricted  as  in  the  type  of  the 
genus,  the  fore  tibiie  are  somewhat  flattened  and  very  heavily  armed, 
with  longer  sjiines  at  tip,  and,  finally,  the  front  shows  quite  a long, 
conic,  corneous  |)rojection,  which  is  evident  in  neither  of  the  other 
species.  It  really  agrees  better  with  my  genus  Chorizagrotis,  but 
the  form  is  not  depressed,  the  eyes  are  narrowed,  and  the  fi’ontal 
jirotuberance  is  quite  different.  It  has  little  or  no  habital  resem- 
blance with  Chorizagrotis,  and  I think  it  best  referi-ed  for  the  j)resent 
to  the  genus  which  in  appearance  it  most  resembles.

On  the  species  of  TRYPOX  V1.01V  inliabitiiig 
America  Xortli  of  Mexico. 

BY  WILLIAM  J.  FOX. 

Through  the  kindness  of  Mr.  E.  T.  Cresson,  I have  had  the  op- 
portunity of  working  over  this  interesting  genus  of  Fossorial  Hy- 
inenoptera.  I do  not  offer  any  suggestion  as  to  the  proper  position 
of  this  genus,  which  has  been  placed  in  the  Larridse  by  most  Euro- 
pean authors.  Mr.  Cresson  has  placed  it  in  the  Crabronidie,  where 
I prefer  to  leave  it  for  the  present  at  least.  Herein  eight  new  species 
have  been  described,  also  two  from  Cuba  and  Mexico,  res|)ectively, 
have  been  added  to  our  fauna.  The  species  are,  as  a rule,  easily 
distinguished,  presenting  characters  which  are  readily  seen.  The 
types  of  all  the  species  herein  described  as  new,  with  the  exception 
of  T.  Johmotii  (which  is  from  my  collection),  and  several  of  Pack- 
ard’s, will  be  found  in  the  collection  of  the  American  Entomological

These  genera  are  separable  liy  the  following  characters.  In  Enclea 
the  second  subcostal  venule  arises  just  beyond  the  end  of  the  discal 
cell,  remote  from  the  origin  of  the  first  subcostal,  w'bile  tbe  first  and 
second  median  venules  arise  as  far  apart  as  the  second  and  third ; 
in  Parasa  the  second  subcostal  venule  arises  just  within  the  cell, 
close  to  the  first  subcostal,  and  the  first  and  second  median  venules 
ari.se  almost  from  a common  point.  Otherwise  the  venation  is  the 
same.  In  the  fore  wings  the  s.-c.  vein  is  remote  from  the  costa  and 
the  costal  arises  from  its  base;  five  s.-c.  nervules,  tbe  origins  of  the 
third  and  fifth  approximately  trisecting  the  vein  beyond  the  cell; 
discal  cross-vein  twice  angulated,  the  independent  vein  arising  from 
its  upper  third  ; a bifid  false  discal  vein  ; median  four-branched  ; 
submedian  present ; internal  bifid  at  base.  The  hind  wings  have  the 
same  venation  in  both  genera. 

Mr.  E.  L.  Graef  has  very  kindly  loaned  me  his  specimens  of  these 
genera  which  comprise  nearly  all  the  species,  and,  from  an  examina-

reaqhing  the  obsolete  subterminal  line,  which  is  lost  in  the  ground  color.  The 
other  green  patch  is  almost  circular,  in  one  example  produced  inwardly  a little 
above  the  discal  dot.  It  is  very  narrowly  separated  from  the  fir.st  jiatch  and 
almost  reaches  the  costa.  It  represents  the  snbapical  patch  of  cippus.  Imt  shows 
no  tendency  to  become  divided.  It  is  follow’ed  by  the  usual  orange  ferniginons 
patch,  trisected  by  the  uervnies  and  reaching  the  obsolete  subterniinal  line. 
Fringes  concolorous  with  primaries,  interlined  with  paler  at  the  base.  Secondaries 
scarcely  paler  than  primaries,  concolorous.  Below,  concolorous  tvith  secondaries 
above,  paler  along  internal  margin  of  primaries  and  base  of  fringe  The  thorax 
is  dark  like  the  fore  wings,  as  in  the  basal  tuft  and  tij)  of  abdomen.  Expanse

I cannot  find  that  this  sjiecies  has  been  figured  or  described  before. 
1 have  seen  it  in  collections  labeled  querceti  and  qaercicola,  but  it 
does  not  correspond  at  all  with  Herrich-Schtlfier’s  figure  of  the.se 
forms.  It  difiers  from  E.  cippus  var.  moidtor  in  its  smaller  size, 
round,  minute,  discal  dot ; the  green  spots  being  rounded  and  not 
triangular,  the  lower  elliptical,  less  deeply  excavated  than  in  cippus, 
the  upper  almost  circular,  not  divided.  The  red  patches  are  smaller 
than  in  cippus,  and  are  distinctly  divided  by  the  veins. 

Euclea  ferruginea  Packard. 

1864. — Pack.  Proc.  Ent.  Soc.  Phil.  Hi,  338. 

This  species  is  fnarked  like  E.  vur.  delphinii,  but  has  in  addition 
a ferruginous  patch  beyond  the  suhterminal  band.  It  is  closely  allied 
to  E.  cippus. 

The  following  is  Dr.  Packard’s  descriittion  : 

"%  more  reddish  than  the  other  species.  . . . Basal  green  spot  small,  slightly 
indented  externally.  Middle  snbai)ical  spot”  [of  the  three  snbapical  green  spots 
which  are  very  variable,  often  confluent]  “large;  lower  one  obsolete,  with  a few 
scales  connecting  it  with  the  reddish  discal  spot,  which  is  margined  above  with 
brown.  Beyond  the  green  spots  the  wing  is  suffused  with  rust-red.  of  a lighter 
blue  than  any  of  the  other  species.  Outer  edge  darker,  like  the  costa.  Beneath 
both  wings  are  alike,  almost  testaceous.  Fringe  brown.”  Habitat,  Canada. 
Expanse  30  mm.

In  tins  the  green  foi’ins  a complete  band,  e.Ycavated  aliove  the 
middle  of  the  internal  margin.  Harris  gives  a good  figure  of  it  in 
“ Insects  Injurious  to  Vegetation,”  page  420. 

The  above  varieties  are  all  connected  by  intergrading  forms. 

The  larva  is  elongate,  rounded,  the  dorsal  i-egion  Hat,  nearly  level, 
of  uniform  width,  rounded  at  the  extremities;  sides  nearly  jierpen- 
dicular.  Head  whitish,  labrum  and  sutures  of  clypeus  yellowish  ; 
ocelli  black  ; jaws  dark  brown  ; retracted  beneath  joint  2.  Along 
the  subdorsal  ridge  of  the  body  on  each  side  is  a row  of  elongated 
spinose  tubercles,  on  joints  3 to  18  inclusive;  those  on  joints  3,  4, 
5,  1 1,  12  and  13,  about  three  times  as  long  as  the  others.  The  spines 
are  short,  black,  and  arise  from  conical  bases.  Another  lateral  row 
of  spinous  tubercles  beginning  on  joint  3,  those  on  joints  G to  12 
situated  above  the  spiracles  (none  on  joint  5)  the  one  on  joint  4 
about  as  long  as  the  subdorsal  one,  the  others  of  uniform  length, 
longer  and  rather  slenderer  than  the  short  subdoi-sal  ones.  A ro'w 
of  dorsal  and  lateral  elliptical  dej)re.ssions,  each  containing  two  ir- 
regular wdiitish  dots,  only  appearing  distinctly  when  the  body  is 
retracted.  The  body  is  covered  wdth  very  minute  transparent  granu- 
lations. Spiracles  very  small,  circular,  projecting,  yellowish. 

The  larva  varies  much  in  color,  from  sordid  ])urplish  to  green; 
there  is  a subdorsal  band  covering  the  row  of  tubercles  which  varies 
from  ferruginous  through  yellow  to  gi’een  (it  may  be  concolorous 
with  the  body)  sometimes  narrowly  and  irregularly  edged  with  black 
or  crimson,  but  always  thrice  interrupted  by  a subquadrate  spot  of 
red  or  dark  brown,  viz.,  between  joints  6 and  7,  9 and  10,  11  and  12.

that  exactly  corresponds  to  Cramer’s  figui-e  in  which  the  greeTi  band  is  broken 
into  three  triangular  spots:  but  this  may  occur.  The  figure  is  too  poor  to  base 
critical  remarks  upon,  but  it  seems  extremely  ju’obable  that  it  is  the  present 
species  that  was  intended.  However,  if  this  should  not  prove  satisfactory,  there 
are  plenty  of  other  names,  as  may  be  seen  from  the  above  .synonymy.  There  is 
no  doubt  about  the  figure  of  delphinii.

terminal  line  and  the  green  patch  is  filled  in  with  a rust-red  shade. 

The  larva,  as  described  by  Mr.  Pearsall,  does  not  seem  to  differ 
from  Prof  French’s  description  of  E.  pceaulatn  more  than  is  the  case 
in  many  examples  oi'  clppus,  and  I expect  that  a good  series  of  moths 
will  show  that  we  have  to  do  with  but  one  species.  I have  been 
able  to  examine  but  one  specimen  of  pcenulata  and  four  of  elUotii,

Thorax  and  primaries  dark  brown,  the  green  patch  on  the  wings  similar  to 
that  of  cippns  in  its  exterior  and  interior  outline,  but  extending  outwardly  to 
the  subterminal  line  and  much  fui'ther  basally  over  the  cell,  reaching  the  base

I know  of  no  description  of  the  larva.  The  species  seems,  in  some 
resitects,  intermediate  between  the  genera  Euclea  and  Parasa,  and  it 
will  be  very  piteresting  to  observe  the  affinities  of  the  larva  when

is  separated  by  a brown  line  from  the  costa  and  reaches  the  internal  margin,  but 
is  not  excavated,  being  only  slightly  waved  above  the  internal  margin.  It

Very  similar  to  P.  viridus  Reak.,  but  the  green  baud  is  still  narrower.  Prima- 
ries wood  brown,  crossed  by  an  oblique  pea -green  baud  that  is  separated  by  a 
brown  line  from  the  costa,  and  is  continued  along  the  internal  margin  to  the 
base  of  the  wing.  The  band  is  edged  with  brown,  but  there  is  no  blackish 
shading  in  the  terminal  space,  though  the  veins  are  marked  with  brown.  Sec-

The  larva  is  somewhat  ovate  in  outline  as  seen  from  above,  the 
last  segment  being  produced  into  a little  pointed  tail.  The  dorsal 
region  is  flat,  highest  at  joint  5,  and  diminishes  to  the  extremities. 
The  subdorsal  ridges  bear  each  a row  of  large  round  warts  covered 
with  spines,  those  on  joints  3,  4,  5,  11  and  12  the  largest,  the  rest 
much  smaller;  a similar  row  above  the  spiracles,  all  small.  The 
head  is  retracted  within  joint  2,  and  this  in  turn  under  joint  3. 
There  is  a double  row  of  blackish  impressed  spots  in  the  dorsal 
region  and  elliptical  depressions  on  the  sides,  but  the  skin  is  nearly 
uniform,  soft  and  smooth.  Color  greenish  brown,  lighter,  more  red-

Closely  related  to  Euclea  is  the  genus  Adoneta  Clem.,  but  in  our 
lists  it  has  not  been  associated  with  its  allies.  It  differs  from  Euclea 
in  the  shorter  pectinations  of  the  autenme  of  the  male  and  the  more 
slender  body.  The  shape  of  the  wings  and  pattern  of  maculation 
are  the  same,  but  the  venation  diffei’s  in  that  Adoneta  has  but  four 
subcostal  venules,  while  Euclea  has  five  in  the  fore  wings,  and  the 
subcostal  vein  in  the  hind  wings  divides  nearer  the  tip  of  the  wing 
in  Adoneta.  These  are  all  weak  characters. 

The  larvse  are  of  the  same  structural  type  in  both  genera,  but 
that  of  Adoneta  is  more  highly  colored. 

From  a consideration  of  characters,  drawn  principally  from  the 
larva,  I would  arrange  the  genera  of  the  Cochlidiie  somewhat  as 
follows,  omitting  the  genera  of  which  I do  not  know  the  larva ; 


L.  flexuosa  and  L.  coesonia  of  Grote,  do  not  belong  to  Lhnacodes, 
and  will  probably  have  to  be  referred  to  Heterogenea  or  an  allied 
genus,  as,  indeed,  Mr.  Grote  has  himself  suggested.* 

Varina  ornata  Neum.,  in  my  opinion,  does  not  belong  to  the  Coch- 
lidiie.f  I have  examined  a 9 specimen  which  Mr.  Graef  has  kindly 
loaned  me,  and  a % from  Prof  Smith.  If  the  moth  is  a bombycid 
at  all,  it  will  have  to  be  referred  to  the  Dasychirie  as  its  characters 
exclude  it  from  the  other  subfamilies.  I wmuld  add  the  following 
characters  to  Mr.  Neumoegen’s  description  of  the  genus : 

Primaries  12-veiued  ; internal  vein  not  furcate  at  base;  median  4-branclied, 
vein  5 nearer  to  4 than  4 to  3 at  base  ; cell  open  ; 6 arising  from  cross-vein  near 
the  subcostal;  a small,  narrow  accessory  cell;  7 from  8 immediately  beyond 
accessory  cell ; 8 and  10  together  from  end  of  accessory  cell ; 9 from  8.  rather 
more  than  half  as  long  as  8.  In  the  secondaries  3 and  4 arise  together  from  the 
end  of  the  median  ; cell  open  ; 5 absent,  represented  by  a fold  ; 7 from  6 beyond 
the  end  of  cell ; 8 touches  the  subcostal  at  about  one-sixth  the  length  of  cell  from 
base 

Tongue  present,  but  weak  ; ocelli  small.  The  thorax  is  covered 
with  scales  and  hair,  and  not  hair  alone,  as  Mr.  Neumoegen  states. 

A knowledge  of  the  larva  of  V-  ornata  is  much  to  be  desired. 

* New  Check  List,  page  63.  I think  that  csesonia  may  prove  to  be  synonymous 
with  Heterogenea  shurtleffii  Pack.  Flexuosa  is  congeneric,  and  may  be  only  a 
form  of  csesonia.

The  species  are  subject  to  considerable  variation,  and  are  usually 
rare.  I have  examined  the  male  genitalia  of  three  species  and  I 
cannot  find  that  they  offer  any  characters  to  afibrd  specific  separa- 
tion. The  supra-anal  plate  in  all  narrows  ra]fidly,  and  is  extended 
backward  in  a long,  evTii,  narrow  prolongation  that  slopes  downward 
without  curving,  being  pilose  beneath.  It  resembles  the  same  part 
in  Datana,  but  is  much  less  strongly  bent  down.  The  side  pieces 
are  simple,  concave  inwardly,  slightly  tapering,  the  ends  rounded. 
The  larvie  are  small  green  Limacodes,  much  resembling  Parasa  fra- 
terna  in  general  shape,  but  lacking  the  spinose  subdorsal  tubercles, 
'fhe  end  of  the  body  is  ])roduced  into  a little  “ tail”  as  in  Parasa, 
which  is  often  marked  with  red  above,  and  this  constitutes  the  only 
colored  marking.  They  feed  on  the  leaves  of  any  deciduous  tree, 
usually  frequenting  the  central  or  more  shaded  parts  of  the  woods. 
Only  one  brood  occurs  each  year  in  New  York,  the  larv’je  maturing 
in  September. 

Dr.  Packard  has  kindly  allowed  me  to  see  his  material  in  this 
genus,  and  I believe  the  following  arrangement  of  species  corresponds 
with  his  opinion.

duste<l  with  ocherous  brown  scales  at  the  base  of  the  wing  and  internal  angle. 
Two  parallel,  oblique,  cbocolate-brown  bands,  the  inner  somewhat  undulate, 
reaching  from  the  basal  third  of  the  inner  margin  to  near  the  center  of  costa, 
the  outer  from  the  basal  two-thirds  of  inner  margin  till  it  joins  a third  curved 
baud,  which  extends  from  the  costa  just  beyond  the  end  of  the  first  band  to 
just  above  the  internal  angle,  where  are  three  superposed,  rounded,  triangular 
white  spots,  the  lower  one  very  small,  all  narrowly  surrounded  by  chocolate- 
brown.  In  the  single  example  before  me  the  space  between  the  first  two  bauds 
is  strongly  filled  in  with  chocolate-brown,  especially  on  the  costal  half  of  the 
wing,  and  this  shade  spreads  outward  diti'usely  beyond  the  third  band  in  the 
center  of  the  wing.  Secondaries  even  paler  than  the  primaries,  dusted  with

The  ground  color  of  the  primaries  is  the  same  as  in  geminata,  the  lines  and 
superposed  white  spots  are  the  same  (though  in  one  example  there  is  a trace  of  a 
fourth  white  spot),  but  the  ocherous  brown  or  sable  brown  and  chocolate-brown 
shadings  are  more  extensive,  w'hile  the  secondaries  are  pulverulent  dark  blackish 
brown.  A male  example  befoi’e  me  (fig.  25)  has  the  basal  space  filled  in  with 
sable  brown,  the  rest  of  the  wing  chocolate-brown,  obscuring  the  lines,  except  a 
subquadrate  apical  space,  where  the  white  ground  color  prevails,  irrorate  with 
brown  scales.  Fringe  paler  at  base.  The  female  (fig.  24)  has  a basal  ocherous 
brown  shading,  but  the  chocolate-brown  shade  is  confined  to  the  space  enclosed 
by  the  second  and  third  bands  at  the  internal  angle,  leaving  the  ground  color  to 
appear  on  the  rest  of  the  wing.  Fringe  ocherous.  Expanse  23 — 27  mm. 

Mr.  Grote’s  ocellata  was  apparently  founded  on  examples  similar 
to  the  female  I have  described  above. 

Larva. — Extremely  similar  to  that  of  geminata.  I have  not  noted 
any  differences.

It  seems  probable  that  this  species  is  only  a very  dark  variety  of 
P.  albipunctata,  but  I have  not  seen  enough  specimens  to  be  able  to 
decide.  Mr.  Grote’s  description  is  substantially  as  follows,  and  well 
characterizes  this  form  : 

“Entirely  blackish,  with  a faint  brown  shading  about  internal  angle,  where 
are  two  white,  unequal  spots.  Fritige  blackish,  concolorous.  interlined  with  pale 
and  with  a distinct  white  fleck  below  apices.  The  usual  lines  on  the  primaries 
are  lost  in  the  ground  color;  the  outer  may  be  made  out,  followed  by  a whitish 
shade  on  costa.  The  costal  edge  at  apices  is  whitish.  Secondaries  concolorous, 
blackish,  paler  beneath  ; the  fringe  is  paler  outwardly.  Expanse  20 — 22  mm.” 

The  species  of  Packardia  may  be  separated  by  the  following  table:

REVISIO]^  OF  THE  DOXACT.E  OF  BOREAE  AMERIC  A. 

BY  CHARLES  W.  LENG,  B.  S. 

Donacia  was  established  by  Fabricius,  in  1775,  for  a European 
species  allied  to  our  mbtilis,  and  the  name,  derived  from  the  Greek 
donax — a reed, — is  indicative  of  the  habits  of  that  and  the  other 
species  comprised  ; all  are  subaquatic,  the  larvie  feeding  in,  the  im- 
agines being  found  about  reeds,  pond  lilies,  Sagittaria  and  other 
water  plants.  The  earliest  descriptions  of  our  species  are  by  foreign 
authors,  Ahrens  and  Kunze,  in  1810  and  1818  respectively.  Thomas 
Say  described  five  in  1823  and  1827,  Newman  added  others,  and 
Kirby  still  more.  In  18-15  there  was  published  a “ Monographie” 
by  Lacordaire,  which  swelled  the  number  considerably.  In  1851, 
Dr.  LeConte  reviewed  the  described  species,  noting  many  synonyms, 
and  in  1873  Crotch  made  a Synopsis,  on  which  the  names  now  in  use 
are  based.  In  all,  about  70  names  have  been  proposed,  and  over 
100  pages  printed  in  descriptions. 

Some  confusion  still  existing,  I have  attempted  in  the  following 
pages  to  give  the  characters  by  which  the  really  distinct  species  may 
be  recognized.  Unassisted,  this  would  have  been  both  presumptuous 
and  impossible;  but  in  advice  and  material  I have  received  so  much 
help,  that  I hope  the  result  may  be  found  satisfactory.  To  Dr.  Geo. 
H.  Horn  I owe  the  free  use  of  a collection  representing  all  the  de- 
scribed species,  each  one  specially  compared  with  the  types  of  Dr. 
LeConte’s  s[>ecies  in  the  Cambridge  Museum  ; as  well  as  the  results 
of  his  observations  on  the  genus  for  many  years  back.  Through 
the  favor  of  Prof.  C.  V.  Riley,  I have  been  entrusted  with  the  col- 
lection of  the  National  Museum.  To  Mr.  Frederick  Blanchard  I 
owe  many  valuable  suggestions  and  sets  of  the  species  living  on  the 
Concord  River.  To  Messrs.  Roberts,  Liebeck,  Westcott,  Wickham, 
Hulbert  and  Sherman,  my  thanks  are  due  for  specimens.  Finally, 
my  friends  on  Staten  Island,  William  T.  Davis  and  J.  C.  Thompson, 
have  freely  given  me  the  use  of  their  collections  and  time. 

Before  using  the  synopsis,  the  reader  should  observe  the  following 
explanation  of  the  terms  employed. 

“ Elytra  truncate  at  tip,  or  subtruncate.”  Under  this  head  are 
included  all  the  forms  that  are  in  the  least  truncate,  or  even  doubt- 


160

fully  SO,  and  the  only  form  excluded  is  that  in  which  the  tip  is  evi- 
dently rounded.  In  such  the  sutural  margin  is  sinuate. 

“ Mesosternum  narrower  than  the  coxa.”  By  this  is  meant  that 
the  portion  of  the  under  surface  seen  between  the  middle  coxjb  is 
narrower  than  those  coxre  separately.  It  is  used  as  a convenient 
measure  of  the  width  of  the  insect,  being  narrowest  in  the  conspicu- 
ously slender  species,  and  may  be  inferred  where  it  is  difficult  to  see, 
as  when  the  insect  is  pasted  on  a point. 

“ Sutural  margin  sinuate  posteriorly.”  In  many  Donacite  the 
elytra  are  declivous  at  the  apex  ; the  elytra  are  closely  joined  at  the 
suture  in  repose,  but  the  margins  on  the  declivous  portion  appear 
double,  and  although  they  truly  meet,  there  is  a second  apparent  mar- 
gin within  the  true  one.  This  second  margin,  starting  not  more  than 
one-fourth  the  length  from  the  tip — often  less — is  sinuate,  or  curved 
more  or  less,  away  from  the  suture.  Thus  a space  somewhat  ellip- 
tical in  shape  is  formed,  sometimes  depressed,  sometimes  in  the  same 
plane  with  the  rest  of  the  elytron,  and  always  destitute  of  punctua- 
tion. This  sinuation  might  also  be  described  as  a sinuate  displace- 
ment of  the  sutural  stria. 

“ Posterior  femora  elliptical.”  In  all  Donacise  but  ru/a,  the  j)os- 
terior  femora  are  decidedly  pedunculate.  In  that  species  the  neck 
is  not  evident,  and  I have  followed  Dr.  LeConte’s  use  of  the  term 
elliptical  to  describe  them,  though  they  are  actually  much  broader 
at  the  apex. 

Certain  characters  are  subject  to  great  individual  variation.  These 
are  the  color,  the  relative  length  of  the  antennal  joints,  the  number 
and  size  of  the  femoral  teeth  or  spines,  and  the  punctuation  and 
sculpture  of  the  upper  surface.  While  diherences  in  these  respects 
are,  to  an  extent,  indicative  of  specific  rank,  it  is  important  that 
they  be  not  carried  too  far,  and  I have  endeavored  to  mark  their 
limits  in  the  descriptions  which  follow  the  synopsis. 

The  dilation  or  extension  into  spinous  ])rocesses  of  the  tibiae  is 
very  evident  in  some  species.  In  pis^eatrix  and  jKilmata  this  is  esj)e- 
cially  true  of  the  middle  tibiae,  ami  a spinule  may  also  be  seen  beneath 
the  dilation.  In  certain  of  the  convex  species  the  dilation  is  more 
apparent  on  the  front  tibiae.  The  character,  however,  varies  greatly 
in  individuals  of  the  same  species,  and  I have  not  made  use  of  it  in 
the  synojLsis. 

The  sexes  in  most  Donaciae  are  widely  differentiated.  As  a rule 
the  females  are  broader,  the  posterior  femora  are  either  without  or 


NORTH  AMERICAN  COLEOPTERA. 


161 


with  fewer  and  weaker  spines  than  the  male,  and  the  last  dorsal 
segment  is  rounded  at  ajiex  and  more  or  less  elongate.  The  males 
besides  being  narrower  and  more  strongly  armed  on  the  femora,  have 
the  pygidium  shorter  and  either  truncate,  arcuately  emarginate,  or 
acutely  triangularly  emarginate,  but  never  rounded.  The  males  of 
palmata  have  the  anterior  tarsi  dilated,  and  the  same  sex  of  piscatrix 
has  the  first  ventral  segment  excavated. 

All  the  species  of  Donacia  are  subaquatic  in  habit,  frequenting 
either  the  pond  lilies,  on  the  broad  leaves  of  which  they  may  be  seen 
from  A{)ril  to  Septendier,  or  the  rushes  and  sedges  that  grow  in  danqi 
places. 

In  the  following  synoptic  table  several  new  names  will  be  noted ; 
these  are : 

cmcticornis  Newn.,  which  was  formerly  called  lucida  Lac.,  or  in 
the  check  lists  rugifrons  Newn. 

pusilla  Say,  which  antedates  and  replaces  cuprea  Ky. 

rufa  Say,  which  antedates  and  replaces  Kirbyi  Lac. 

The  scheme  proposed  is  as  follows : 

Head  and  thorax  evidently  pubescent  above Group  A. 

Head  occasionally,  thorax  never  pubescent. 

Elytra  truncate  at  tip,  or  subtruncate. 

Form  decidedly  flattened  ; mesosternum  about  as  broad  as  each  coxa. 

Group  B. 

Form  more  convex;  mesosternum  narrower  than  the  coxa Group  C. 

Elytra  rounded  at  tip,  the  sutural  marsin  sinuate  posteriorly;  form  convex; 
mesosternum  narrow  Group  D. 

Group  A. 

Three  species  fall  into  this  group  which  are  not  otherwise  at  all 
similar.  It  will  be  noted  puhes^cens  is  the  only  species  with  pu- 
bescent elytra,  and  puhicollis  the  only  one  with  the  femora  destitute 
of  teeth  or  spines  in  both  sexes.  A badly  rubbed  specimen  of  hir- 
ticollis  might  be  placed  in  the  next  group,  from  all  the  species  of 
which  it  may  be  distinguished  by  the  very  small  tooth  of  the  femora, 
which  is  often  reduced  to  a mere  lump.  The  species  are  separated 
thus : 

Elytra  without  pubescence;  posterior  femora  with  a small  tooth. ..liirticolli;S. 


Elytra  without  pubescence;  posterior  femora  simple ptibicollis. 

Elytra  evidently  pubescent;  posterior  femora  toothed  |>iibesceii$$.

CHARLES  AV.  LENG. 


Group  B. 

The  s]iecies  comprised  in  this  grou])  are  similar  in  appearance,  all 
being  evidently  flattened  above  ; the  first  ventral  segment  is  not  only 
flattened,  but  longer  than  all  the  others  combined ; the  color  is 
frequently  testaceous  ; the  middle  tibite  are  expanded  at  tip  and  are 
armed  beneath  with  a spinule ; the  mesosternum  is  conspicuously 
broad  in  all  excej)t  piscatrix  male.  These  are  the  species  which 
frequent  the  pond  lilies,  and  Mr.  Blanchard  has  suggested  that  their 
great  breadth  of  beam  indicates  an  adaptation  to  their  particularly 
aquatic  existence,  in  which  connection  it  is  worthy  of  note  that  the 
])ubescence  of  the  under  surface,  characteristic  of  the  tribe,  is  in 
them  especially  develojied.  The  species  are : 

Thorax  narrowed  in  front;  posterior  femora  plnridentate  male,  simple  female. 

floridte. 

Thorax  quadrate,  or  wider  in  front;  posterior  femora  dentate  in  both  sexes,  the 


male  often  hi-  or  tridentate. 

Auteunffi  with  second  and  third  joints  nearly  equal ciiicticoriiis. 

Auteuuffi  with  third  joint  much  longer  than  second. 

Elytra  truncate. 

Anterior  tarsi  of  male  dilated palinata. 

.Anterior  tarsi  simple liypoleiica. 

Elytra  subtruucate,  form  more  convex;  first  ventral  segment  of  % exca- 
vated  piscatri.x. 


The  specimens  which  I include  under  the  name  cincUcornis  may 
be  divided  into  three  species  or  varieties  or  races  as  follows: 

Prothorax  not  coarsely  punctate. 

Posterior  femora  male  very  large  and  strongly  dentate,  posterior  tibiae  curved 

and  serrate lucida. 

Posterior  femora  less  developed unnamed. 

Prothorax  punctate  at  base  and  apex  only;  posterior  femora  less  developed. 

tibiae  straight,  or  nearly  so proxima. 

Prothorax  coarsely  punctate  over  its  entire  surface  ; femora  and  tibiai  as  in  pre- 
ceding   magnifica. 

From  the  number  of  specimens  before  me,  showing  all  gradations 
in  the  thoracic  sculpture  and  femoral  armature,  I do  not  think  these 
forms  can  be  recognized  as  species,  and  I suggest  that  they  be  placed 
in  our  lists  as  varieties. 

Group  C. 

'fhis  group  includes  subtilis,  of  which  the  female  might,  with  equal 
propriety,  be  placed  in  the  preceding  group,  though  the  male  is  de- 
cidedly more  convex ; and  several  species  which,  by  their  convex 
form,  are  associated  with  the  last  group,  l)ut  differ  in  the  truncate

elytral  tip.  Two  species,  Harrisu  and  distincta,  present  also  the 
peculiar  sinuation  of  the  sutural  margin  of  the  elytra  which  charac- 
terizes that  group.  This  consists  in  the  displacement  of  the  margin 
for  a space  equal  to  one-fourth  the  length  of  the  elytron,  whereby, 
wdien  the  elytra  are  closed  in  i-epose,  an  elliptical  space  is  formed 
hounded  by  the  displaced  margins.  In  Harrisii  the  margin  appears 
double,  and  the  inner  sinuate  portion  is  in  a higher  plane  than  the 
outer  straight  portion.  In  most  of  the  species  the  material  which 
fills  the  sinuation  is  in  the  same  plane. 

Eyes  of  normal  size;  sutural  margin  of  elytra  straight,  except  in  distincta. 

Thorax  punctate,  not  or  scarcely  tuberculate. 

Thoracic  punctures  coarse,  uniform siiblilis. 

Thoracic  punctures  uneven,  finer  punctures  mixed  through  the  coarser. 


poroi^ioollis. 

Thorax  uneven  on  the  disc,  tuberculate  on  the  sides. 

Sutural  margin  of  elytra  straight. 

Elytra  with  two  transverse  indentations cPqiialis. 

Elytra  not  indented ; posterior  femora  male  dentate,  female  simple. 

t II  bore  II  lata. 

Sutural  margin  of  elytra  sinuate distincta. 


Eyes  small;  thorax  tuberculate;  sutural  margin  of  elytra  sinuate.... Harrisii. 

Of  these  species,  porosicolUs  seems  rare ; the  specimens  I have  are 
far  more  slender  than  any  other,  and  there  is  an  appearance  of  an 
abrupt  demarkation  on  the  sides  of  the  elytra.  Inasmuch  as  siibtilis, 
its  nearest  ally,  is  constant  in  the  style  of  its  punctuation,  I have 
preferred  to  use  that  character  for  the  separation  of  the  two  species. 
1'he  specimens  under  subiilis  may  be  separated  thus : 

Thorax  straight  on  the  sides;  second  and  third  antennal  joints  subequal. 

Thorax  constricted  at  middle  ; third  joint  of  antennse  longer  than  second,..r!tgos«. 

but  on  account  of  the  variations  observed  in  these  characters  in  other 
species,  I doubt  rugosa  being  a distinct  species  ; torosa  Lee.  is  included 
with  distincta. 


Group  D. 

The  species  here  included  are  readily  distinguished  by  the  convex 
form,  rounded  elytra  and  sinuate  sutural  margin.  They  may  be 
se])arated  as  follows : 

Thorax  depre.ssed  without  basal  and  medial  groove. 


Posterior  femora  dentate  in  both  sexes piisilla. 

Posterior  femora  dentate  in  male  only Icinoralis.

medial  groove.

Tlie  species  contained  in  this  group  may  be  arranged  in  jtairs  as 
placed  above  ; the  differences,  however,  between  pudlla  and /(?Hior«^hs, 
emcirginata  and  metallica,  jiavi2)es  and  rufa,  are  feeble.  The  first 
pair  are  readily  isolated  by  the  depressed  thorax,  the  second  by  the 
dark  legs,  the  third  by  the  yellow  legs  and  more  convex  thorax.  It 
must  be  observed  that  the  femoral  tooth  is  less  developed  in  the 
females  throughout  the  genus,  and  is  particularly  weak  in  this  group  ; 
femora  are  subject  to  some  variation  in  form  and  the  punctuation  is 
inconstant  in  many  of  the  preceding  species,  so  that,  while  the  con- 
siderable number  of  specimens  before  me  are  separable  by  the  char- 
acters given,  the  reader  must  be  prepared  to  find  some  which,  in 
these  respects,  will  vary  from  the  tyj)ical  form. 

Descriptions  and  Notes. 

In  the  following  pages  I propose  to  copy  either  the  original  de- 
scription, or  that  of  Dr.  LeConte’s  paper,  su})plementing  each  with 
descriptions  of  those  parts  especially  useful  in  recognizing  the  si)ecies 
and  stating  the  sexual  differences  and  the  variations  I have  observed. 
The  bibliography  and  synonymy  is  placed  at  the  end.

single  specimen  taken  in  lat.  65°. 

“ Body  underneatb  covered  with  a thick  coat  of  decumbent  pile  resembling 
.satin  and  shining  like  silver.  Head  hoary  from  inconspicuous  bair.s,  most  mi- 
nutely and  couflueutly  punctured  with  a slight  interocular  channel  with  an 
obtuse  ridge  on  each  side;  antennse  with  tbe  second  and  third  joints  equal  in

black,  punctured  in  rows,  whose  interstices  are  wrinkled  ; posterior  tbigbs  with 
a single  short  obtusangular  tooth.  This  jiretty  species  comes  near  bidens  Oliv., 
which  I always  find  on  Potamogeton  natans,  but  it  is  sufficiently  distinguished  by 
its  black  thorax  hoary  from  down  and  legs  without  any  red.”

I cannot  find  any  description  agreeing  with  the  characters  of  this 
insect.  It  looks  like  a small  lucida,  but  differs  not  only  in  the  sim- 
ple femora  of  the  female,  but  in  the  form  of  the  thorax.  I have 
seen  only  three  specimens,  in  the  National  Museum. 

I>.  ciiicticoriiis  Newman.  Original  description  translated. 

“Antenme  elongate,  the  basal  joint  pale,  the  apical  black:  vertex  shining; 
prothorax  quadrate,  most  minutely  punctured,  with  an  impressed  dorsal  line; 
head  and  prothorax  black  seneous,  elytra  testaceous,  shining;  elytral  apex  trun- 
cate; metafemora  elongate,  incrassate,  bidentate;  legs  testaceous,  femora  with 
two  black  vittae.  [Corp.  long.  .325  nnc.,  lat.  .1  unc.] 

This  species  has  been  long  known  as  lucida  Lac.  The  synonymy 
was  pointed  out  by  Dr.  Horn  some  time  ago,  [lint.  Am.  I,  p.  9]  but 
has  not  been  corrected  in  the  Check  List.  Lacordaire’s  descri[)tion 
of  lucida  is  as  follows ; 

“Moderately  elongate,  above  metallic  green,  very  shining,  elytra  rufe.scent; 
beneath  densely  cinereo-sericeous ; antennte  and  legs  rufous,  maculate  with 
black  ; protborax  transverse,  slightly  narrowed  behind,  the  angles  obtuse  but 
distinct,  the  margin  in  front  and  at  the  middle  of  the  base,  reflexed  ; towards 
tbe  front  on  each  side  obsoletely  tuberculate;  above  vaguely  rugose,  with  a 
dorsal  sulcus  abbreviated  behind  and  an  impressed  puncture;  elytra  flattened 
on  the  disc,  declivous  at  apex,  which  is  squarely  truncate;  bi-impressed,  punctato- 
striate,  interstices  flat,  vaguely  transversely  rugose.  Length  3j — 4i  lines; 
width  li — Ij  lines.” 

Mesosternum  as  broad  as  the  coxa;  first  ventral  segment  longer  than  the  meta- 
sternum;  third  joint  of  antennse  about  equal  to  the  second;  posterior  femora 
incrassate  and  dentate. 

Male. — Pygidium  truncate;  posterior  femora  strongly  incrassate  and  sharply 
dentate,  or  even  tridentate. 

Female. — Pygidium  elongate  and  rounded  at  apex;  posterior  femora  feebly 
incras.sate  and  unidentate. 

The  posterior  tibiae  are  serrate  in  well  developed  specimens  % .

to  an  entirely  ditierent  insect  belonging  to  the  last  group.  The  va- 
riations observed  are  in  size,  as  indicated  above  ; in  color,  which  may 
be  a uniform  greenish  black,  or  a much  lighter  color  almost  testace- 
ous, or  a combination  of  both  ; in  the  femoral  teeth,  which  depend 
in  number  and  size  upon  the  development  of  the  insect,  and  may  be 
traced  through  gradually  weakening  forms,  from  three  prominent 
spines  in  the  male  to  a single  obtuse  tooth  in  the  female ; and  in  the 
relative  length  of  the  antennal  joints,  the  third  being  usually  as 
short  as  the  second,  but  sometimes  evidently  longer.  It  is  never 
twTce  as  long,  however,  as  in  the  following  species.  Although  se- 
lected specimens  can  be  made  to  look  very  different,  I can  find  no 
character  in  these  variations  to  base  even  a variety. 

With  the  punctuation  of  the  thorax,  it  is  somewhat  different.  In- 
termediate specimens  do  occur,  and  indicate  the  close  relation  be- 
tw’een  cincticornis  and  its  varieties  proxima  and  magnijica,  but  the 
greater  number  are  readily  separated,  as  indicated  in  the  synopsis. 

Food-plant  is  undoubtedly  the  pond  lily,  Nuphar  advena.  I have 
always  found  the  insect  on  this  plant,  frequently  within  its  yellow 
flowers,  and  Mr.  Roberts  has  also  in  Vermont,  and  Mr.  Blanchard 
in  Massachusetts.  Furthermore,  it  does  not  occur  in  localities  where 
there  are  no  lily  ponds.  The  white  water  lily,  Nymphcea  odorata, 
occurs  in  many  ])onds  with  the  Nuphar,  and  the  insects  show  no 
partiality  for  it  in  the  imago  stage.  The  original  descriptions  of  the 
varieties  are : 

Var.  proxiina  Kirby. — “Thighs  bidentate,  witli  one  tooth  minute;  above 
dark  violet  glossy,  head  rather  bronzed  ; punctures  of  the  elytra  green  gilt;  body 
underneath  covered  with  a satin  silver  pile.  Length  5 lines.  Taken  in  Canada 
by  Dr.  Bigsby.  Body  a little  flattened,  covered  uuderneatb  with  a dense  coat 
of  glittering  silver  pile  resembling  satin.  Head  a little  bronzed,  channeled 
between  the  eyes,  minutely  punctured,  palpi  testaceous ; antennae  entirely  black  ; 
prothorax  in  the  disc  dark  violet  and  channeled,  sides  bronzed  and  impressed, 
anterior  tubercles  not  prominent;  scutellum  bronzed  ; elytra  nearly  black,  with 
a slight  tint  of  violet,  punctures  green  gilt,  interstices  of  the  rows  not  wrinkled, 
an  anterior  impression  near  the  suture,  rounded  at  the  apex;  posterior  legs  long, 
with  the  thighs  somewhat  curved,  attenuated  at  the  base,  curved  at  the  apex, 
with  two  teeth  placed  consecutively,  the  first  long,  slender  and  acute;  the  last 
wide,  short  and  denticulated  posteriorly.  This  species  is  nearly  related  to  cras- 
sipes  Fab.,  but  the  antenuse  and  legs  are  entirely  black,  and  the  teeth  on  the 
posterior  thighs  are  not  equal.” 

Length  8 — 11  mm. ; .32 — .44  inch.  Habitat. — Cal.,  Idaho,  Hud.  Bay  Terr.,  Can.,

Var.  rufescens  Lacordaire,  is  smaller,  and  has  the  antennal  joints 
very  moderately  thickened  externally.  It  occurs  near  Lowell, 
Mass.,  on  the  lily  “pads,”  and  I am  indebted  to  Mr.  Blanchard  for 
my  specimens  as  well  as  for  pointing  out  its  differentiation.  It  is 
also  found  in  New  York  by  Mr.  Sherman,  and  in  New  Jersey  by 
Mr.  Liebeck,  and  is  possibly  mixed  in  collections  with  cincticornis, 
from  which  it  may  be  separated  by  the  length  of  the  third  antennal 
joint.

D.  piseatri.v  Lacordaire  Original  description  translated. 

“Pale  rufous,  opaque;  chest  and  head  blackish;  beneath  cinereo-sericeous. 
Prothorax  subtransverse,  somewhat  narrowed  at  base,  anterior  angles  obsolete, 
the  posterior  distinct;  bituberculate  on  each  side,  smooth  above,  impressed  at

interstices  slightly  convex,  subporcated,  on  all  sides  very  slightly  coriaceous. 
Length  44  lines;  width  lines.” 

Mesostenmm  as  broad  as  the  coxa  female,  narrow'er  male  ; first  ventral  segment 
about  as  long  as  the  raeta.sternum  ; elytral  tip  subtruncate,  not  so  squarely  ter- 
minated as  in  the  preceding;  form  more  convex,  making  an  approach  to  the 
convex  forms  of  following  groui)s ; antennse  comparatively  shorter  and  slightly 
stouter;  femora  dentate,  middle  tibiae  unsymmetrically  dilated  at  tip. 

Male,  pygidium  subtruncate;  posterior  femora  strongly  dentate  or  bidentate; 
first  ventral  segment  excavated  at  middle,  i.e.,  there  is  a depressed  pit,  such  as 
the  point  of  a dull  pencil  might  have  formed. 

Female,  pygidium  elongate,  rounded  at  tip;  posterior  femora  unidentate,  first 
ventral  not  excavated. 

Varies  in  color  from  the  typical  “ pale  rufous”  to  a dark  bronze 
just  as  the  preceding  species  do;  alutacea  Lee.  is  the  name  ap{)lied 
to  the  darker  forms  in  many  collections,  but  it  is  impossible  to  draw 
any  line  between  them.  The  intermediate  forms  are  among  the  most 
beautiful  specimens  in  the  genus,  the  suture  being  broadly  bronzed 
and  the  other  part  of  the  elytra  golden  testaceous. 

This  species  occurs  with  the  preceding  on  the  leaves  and  in  the 
dowers  of  Nuphar,  and  I have  taken  it  on  the  roots  of  that  plant, 
where  it  pupates,  enclosed  in  an  oval  cocoon  of  leathery  consistency. 
It  is  mixed  in  most  collections  with  palmata,  and  the  females  are  not

This  species  is  very  abuiulunt  on  Staten  Island  at  a jtond  Itordered 
l)y  marshy  ground,  where  grow  a nninber  of  sedges  and  grasses,  on 
whicli  the  insects  principally  occur.  They  wander  to  the  lilv  pads, 
but  do  not  occur  in  ponds  where  the  lilies  alone  are  abundant.  I 
therefore  conclude  that  they  live  on  these  sedges.  Mr.  Clarence  M. 
Weed  has  noted  their  abundance  in  a similar  situation  in  Ohio  ( Bull. 
Ohio  Ex.  Station,  1889).

Dr.  John  Hamilton  has  advised  me  of  the  following  facts  regard- 
ing the  habits  of  this  species : “ I have  taken  (equaUs  in  April  in  a 
swampy  meadow  just  thawing  out.  The  insects  were  in  the  bunches 
of  sedge  and  coarse  grass,  and  must  have  been  imbeded  in  ice  most 
of  the  Winter,  or  under  water  much  of  the  time.  I take  the  same 
species  in  this  swamp  in  July  on  the  sedge,  and  with  it  I once  took 
a few  specimens  of  mbtilis.  This  meadow  is  bottom  ground  between 
two  hills.” 

I>.  tuberciilata  Lacordaire.  Original  description  translated. 

“Oblong,  above  jeneo-cupreous  shining,  beneath  cinereo-sericeous ; abdomen, 
antenupe  and  legs  rufescent.  tiie  femora  broadly  metallic  green  towards  apex; 
prothorax  subquadrate,  narrowed  at  the  base,  anterior  angles  prominent,  the  sides 
strongly  tuberculate  anteriorly,  the  disc  very  convex,  slightly  closely  rugose, 
with  a deep  dorsal  channel,  entire;  elytra  short,  oblong,  the  apices  declivous, 
separately  rounded,  above  slightly  depressed,  evidently  impressed,  finely  punc- 
tato  striate,  punctures  aviculate,  interstices  flat,  finely  transversely  rugose. 
Long.  2|  lines.  Lat.  lines.” 

Mesosternnm  nearly  as  broad  as  the  coxa;  first  ventral  aliout  as  long  as  the 
metasternuin  ; elytra  slightly  dehiscent  at  tip,  which  is  distinctly  truncate,  the 
impressed  or  indented  s])aces  on  the  disc  not  deep  as  in  the  preceding,  but  barely 
evident;  antennse  with  third  joint  twice  as  long  as  second;  femora  difleriug  in 
the  sexes. 

Male,  pygidium  truncate,  emarginate  at  middle;  posterior  femora  with  an 
acute  tooth.  Female,  pygidium  elongate,  rounded  at  tip,  posterior  femora  usually 
unarmed,  at  most  a feeble  rudimentary  tooth. 

This  species  is  usually  quite  rufous,  tinged  with  metallic  lustre, 
but  varies  to  a darker  color,  nearly  as  cupreous  as  mbtilis.  It  was 
found  at  Jamesburg,  N.  J.,  July  4,  1890,  in  large  numbers  on  the 
Sagittaria  in  the  cranberry  bogs  not  mixed  with  any  other  species. 
It  does  not  occur  in  this  vicinity  on  the  lilies  or  reeds,  and  I have 
no  doubt  the  Sagittaria  is  its  food-plant.

Male,  pygifliuin  acutely  eiuargiiiate  at  luiddle;  female,  simply  rounded. 

Length  7 — 9 mm. ; .28— .36  inch.  Habitat. — Mich..  Wis..  Mass. 

The  sutural  margin  of  the  elytra  is  slightly  sinuate  in  this  species 
for  a short  distance,  not  exceeding  one-tenth  the  length,  near  the 
apex.  It  seems  to  be  rare,  and  1 cannot  separate  it  with  the  si)eci- 
mens  before  me  from  torosa  Lee.  It  would  be  hazardous,  however, 
to  unite  them  without  a larger  series  for  coni[)arison. 

Var.  toi'osa  LeConte.  Original  description  translated. 

“ Slightly  elongate,  blackish  violet,  head  strongly  torose:  thorax  alutaceous, 
sj)ar.sely,  finely  punctate,  somewhat  elongate,  narrowed  behind,  angles  prominent, 
sides  tuberculate,  disc  suhcanaliculate ; elytra  scarcely  triangular,  apex  rounded, 
truncate,  the  disc  rugose,  bi-impressed  ; posterior  femora  moderately  clavate, 
armed  with  a moderately  acute  tooth.  Long.  .25.  Mass.” 

Mesosternum,  etc.,  as  in  distincta. 

Length  6 — 7 mm.;  .24 —.25  inch.  Habitat. — Mass.,  D.  C.,  111.,  Iowa. 

I>.  Har  risii  LeConte.  Original  descriptiefu  translated. 

“Elongate,  eyes  scarcely  prominent,  orbit  absent;  elytra  convex,  apex  trun- 
cate, antennae  slender,  the  second  joint  shorter;  aeneous,  head  scarcely  torose, 
thorax  elongate,  densely  rugosely  punctate,  scarcely  narrowed  behind,  angles 
prominent;  slightly  canaliculate  impressed  in  front  of  the  base,  the  lateral  tu- 
bercle scarcely  prominent,  the  basal  impression  well  defined.  Elytra  parallel, 
obliquely  narrowed  towards  the  apex,  strongly  punctured  in  row's,  finely  rugose. 
Antennae  annulate,  the  second  joint  half  as  long  as  the  others.  Long,  .42.  Pa. 
Very  rare. 

“ Male,  posterior  femora  iucrassate,  armed  with  an  acute  tooth. 

“Female,  posterior  femora  feebly  iucrassate,  mutic  (not  dentate). 

“ A singular  species,  the  small  eyes  suggesting  Statira  of  the  Lagriidae.” 

Mesosternum  narrow'er  than  the  coxa  ; first  ventral  about  equal  to  the  metaster- 
num ; elytral  tip  truncate. 

Pygidium  acutely  emarginate  male,  rounded  quite  broadly  female.  The  female 
pygidium  appears  to  be  emarginate  in  two  specimens,  being  somewhat  elevated 
at  middle,  probablj"  by  accident. 

This  is  the  only  large  species  with  the  sinuate  elytral  suture. 

Length  10 — 11  mm. ; .40 — .44  inch.  Habitat. — Mass.,  Conn.,  N.  Y. 

D.  piisilla  Say.  Original  description. 

“Green,  elytra  brassy,  tibiae  and  tarsi  rufous,  second  and  third  joints  of  an- 
tennae equal.  Head  brassy  green,  very  densely  and  couflueutly  punctured,  a 
well  impressed  frontal  line,  lateral  lines  none,  no  a])pearance  of  frontal  tnl>ercles; 
antennae  short,  much  less  than  half  the  length  of  the  body,  .second  and  third 
joints  equal,  fourth  hardly  longer,  joints  dull  rufous,  blackish  at  tip.  Thorax 
green,  tinged  with  brassy,  longer  than  broad,  as  densely  punctured  as  head,  mid- 
dle and  anterior  edge  a little  elevated,  longitudinal  line  none,  lateral  tubercles 
obvious.  Elytra  brassy  green,  a little  tinged  with  cupreous,  with  striae  of  punc- 
tures, three  longitudinal  indentations  near  the  suture,  of  which  the  anterior  one 
is  widest  and  deepest,  with  a slight  impressed  line  extending  obliquely  to  the 
base,  tip  decu'rved  and  rounded.  Beneath  green,  tinged  with  brassy,  feet  rufous, 
thighs  at  tip  brassy  green,  posterior  pair  with  a prominent  angle  beneath. 
Length  rather  more  than  i inch.” 

This  species  has  been  known  as  eiiprea  Kirby,  from  which  it  does 
not  differ.  I subjoin  Kirby’s  description  also:

“Above  copper  colored,  glossy  underneath  with  a thick  coat  of  cinereous  pile: 
antennae  black,  legs  obscurely  rufous,  posterior  thighs  uuidentate,  prothorax 
subtransverse.  Length  of  body  lines.  Taken  in  Canada  by  Dr.  Bigsby.  . . . 
Head  downy  channeled,  mouth  and  palpi  rufous,  mandibles  and  antennae  black  ; 
prothorax  rather  wider  than  long,  very  minutely,  thickly  and  confluently  punc- 
tured and  wrinkled,  channeled  with  a pair  of  impressions  on  each  side,  anterior 
tubercles  not  prominent,  scutellum  downy;  elytra  very  glossy,  punctured  in 
rows,  a single  anterior  impression  near  the  suture,  truncated  at  the  apex  ; three 
intermediate  segments  of  the  abdomen  have  a yellow  margin;  legs  obscurely 
rufous,  thighs  bronzed  in  the  middle,  posterior  thighs  with  a minute  tooth  near 
the  apex.” 

Mesosternum  narrower  than  the  coxa;  first  ventral  shovtGr  than  the  metaster- 
num; elytral  tip  rounded,  not  truncate,  as  described  above.  It  is  very  little 
rounded,  but  compared  with  subtilis  it  is  seen  to  be  distinctly  rounded.  Sutural 
margin  sinuate  near  the  apex,  the  sinuation  filled  with  a glittering  impunctate 
plate;  form  convex,  thorax  depressed,  third  and  second  joints  of  antennae  sub- 
equal. 

3Iale.  pygidium  truncate  and  slightly  arcuately  emarginate. 

Female,  pygidium  more  elongate,  rounded ; tooth  of  posterior  femora  smaller. 
The  sexes  of  cuprea  are  not  readily  distinguished. 

The  color  varies  from  briglit  reddish  or  cupreous,  through  many 
shades  of  metallic  color,  to  a form  nearly  black.  The  legs  are  yel- 
low or  rufous  in  the  majority  of  specimens ; in  a few  they  are  nearly 
black,  and  constitute  the  variety  pyritosa  Lee. 

The  relative  length  of  the  antennal  joints  is  not  constant,  and 
will  not  serve  to  separate  pyritosa,  as  a species,  as  stated  by  Mr. 
Crotch.  From  some  variation  observed  in  the  specimens  before  me, 
I am  doubtful  if  it  is  a sufficiently  defined  variety  even  to  be  con- 
tinued in  the  list. 

The  indentations  of  the  elytra  are  somewhat  variable  in  depth 
and  consequent  distinctness,  but  are  never  very  marked.  The  species 
is  sometimes  mixed  in  collections  with  CBqualis  Say,  and  the  depth 
of  these  indentations  afford  a convenient  index  for  their  separation.

are  labeled  Mass.,  N.  Y.  and  N.  J.,  and  are  perhaps  correct,  but  the  species  ap- 
pears to  be  more  abundant  in  the  North  and  West. 

I),  feiuoralis  Kirby.  Original  description. 

“Body  bronzed,  gilded  with  a greenish  tint,  very  minutely  and  thickly  punc- 
tured, not  conspicuously  hairy  underueath.  Frontal  channel  slight;  antennse. 
except  the  scape,  wiiich  is  bronzed,  and  mouth  rufous;  prothorax  with  an  im- 
pression above  the  scutellum,  anterior  tubercles  more  than  usually  prominent, 
scutel  rather  large.  Elytra  with  single  slight  anterior  impression  adjoining  the 
suture  ; legs  rufous,  but  the  thighs,  which  are  much  iucrassated,  excejjt  the  base 
and  summit  are  green  bronzed,  posterior  thigh  without  any  tooth.  Ahdomen  as 
in  the  preceding  species,  yellow.  This  species  seems  nearly  related  to  pusilla.” 
The  posterior  thighs  are  dentate  in  male,  and  the  above  description  was  made

an  ini]iression  near  the  suture,  last  dorsal  segment  of  the  abdomen  emarginate. 
thighs  very  thick,  bronzed,  posterior  one  with  a stout  tooth.  This  species  comes 
very  near  sericea.  hut  it  is  sufficiently  distinguished  by  the  deeply  notched  podex, 
the  silver  pile  that  clotiies  its  body  underneath,  which  in  that  species  has  a 
golden  lustre.” 

Mesosternum  narrower  than  the  coxa;  first  ventral  segment  shorter  than  the

Mesosternum,  etc.,  as  in  the  preceding,  and  the  sexual  characters  are  the  same. 
No  variations  are  observed  in  color,  and  the  insect  is  readily  known  by  the  con- 
vex shining  thorax  almost  destitute  of  punctuation. 

Length  7 — 7i  mm.;  .28 —.30  inch.  Habitat — Can.,  N.  H.,  Mass.,  N.  Y.,  Ohio, 
and  one  specimen  is  labeled  “Texas.” 

Apparently  more  rare,  the  collections  examined  containing  to- 
gether sixteen  specimens. 


Synonymy  and  Bibliography. 

The  greater  part  of  the  following  synonymy  is  derived  from  the 
“ Catalogus”  of  Gemminger  and  Harold,  from  Dr.  LeConte’s  Syn- 
oj)sis,  or  from  Mr.  Crotch’s  paper.  Of  the  remainder  a part  is  due 
to  comparisons  made  by  Dr.  Horn  with  the  LeConte  types  at  Cam- 
bridge, and  the  balance  is  the  result  of  a comparison  of  the  published 
descriptions.  All  the  older  names  have  been  recognized,  and  in 
some  instances  those  which  have  been  in  use  have  had  to  give  way 
to  them.

Kovi!«ion  of  the  g;eiiera  and  species  of  AISTHOXOMIRJI 
iiiliabitiiig  North  America. 

BY  WILLIAM  G.  DIETZ,  M.  D. 

iSince  the  publication  of  “ The  Rhynchophora,”  (Proc.  Anier. 
Philos.  Soc.  1876)  but  few  new  species  belonging  to  the  tribe  under 
consideration  have  been  described,  while  the  amount  of  material  ac- 
cumulated in  our  collections  has  been  considerable.  It  was  my  in- 
tention, originally,  to  confine  the  following  essay  to  Anthonomus 
proper ; the  discovery,  however,  of  new  and  im})ortant  characters, 
as  well  as  a greater  appreciation  of  others  heretofore  deemed  of  but 
secondary  importance  in  the  classification  of  genera  of  this  tribe, 
has  led  me,  step  by  step,  to  include  all  the  genera  and  species  oc- 
curring within  our  faunal  limits.  The  Anthonomini  of  Europe 
have  been  made  the  subject  of  a monogra})h  by  Desbrochers  des 
Loges  (Monographic  des  Balaninidse  et  Anthonomidie  d’Europe  et 
de  confines  Mediterranees,  1867),  which  has,  however,  scarcely  offered 
a suggestion  that  might  have  aided  me  in  the  study  of  our  North 
American  species.  The  genus  Orchestes  was  similarly  treated  by 
Brisout  (Monogr.  Ann.  Fr.  1865).  Very  recently  a paper  has  been 
published  on  the  species  of  Anthonomus  inhabiting  Great  Britain  ; 
the  latter  publication  I have  not  seen. 

In  taking  a general  comparative  survey  of  the  present  tribe  of 
Curculionidie,  as  presented  by  our  own  with  that  of  the  European 
fauna,  one  is  struck  with  the  few  points  of  close  similarity  encoun- 
tered. Referring  to  Anthonomus  proper,  the  European  species,  as 
far  as  I am  able  to  judge  by  the  not  inconsiderable  number  repre- 
sented in  my  collection,  present  far  greater  uniformity,  structurally 
as  well  as  in  general  habitus,  than  our  own.  In  all  of  them  the 
funicle  of  the  antennie  consists  of  seven  joints,  and  species  entirely 
clothed  with  scales  do  not  occur.  The  European  genus  Bradybatus 
Germ.,  in  which  the  claws  are  connate  at  base,  is  not  represented  in 
our  fauna. 

In  defining  the  limits  of  the  tribe,  a modification  of  LeConte’s 
arrangement  becomes  necessary.  Several  new  genera  have  been 
included,  whose  position  is  somewhat  doubtful,  and  which,  with  equal 
j)ropriety,  might  have  been  placed  in  some  other  tribes  of  the  Me-

corrhyndiid  series.  One  of  these,  Alycodes,  whose  affinity  to  the 
Erirrliini  is  well  shown  by  the  formation  of  tlie  ventral  segments, 
the  covered  pygidiiim  and  the  sim])le  claws,  and  by  its  toothed 
femora,  would  have  to  he  placed  after  Dorytomus,  hut  the  obliquelv 
truncated  anterior  thoracic  opening,  the  prosternum  short  in  front 
of  tlie  coxffi,  the  antennal  formation,  etc.,  have  induced  me  to  jilace 
it  in  the  })resent  tribe.  Another  aberrant  genus,  Euclyptus,  resem- 
l)les  Xoto/ovius  basu/is  Lee.  in  its  general  appearance,  and  also  in  the 
ventral  formation  ; the  prosternum,  however,  is  short  in  front  of  the 
coxffi,  the  j)ygidium  freely  exposed,  and  the  appendiculate  claws 
warrant  its  position  here.  Elleschus,  placed  by  Lacordaire  among 
the  Tychiides,  I have  retained  in  the  present  tribe;  the  second,  third 
and  fourth  ventral  sutures  are  slightly  bent  backward  at  the  sides; 
this  character  is  also  noticed  in  a few  Anthonomi  (A.  elegam,  jinii- 
perinu-s).  Simple  claws  occur  in  a small  number  of  species,  dis- 
tributed among  several  genera.  This  abnormality  in  the  present 
tribe  is  the  final  result  of  a gradual  reduction  in  development,  passing 
from  the  bifid  claws  of  some  Anthonomi  (Anthonomorphus)  to  the 
very  small,  though  distinct  tooth  of  Chelonychus  and  a few  others, 
to  disappears  altogether  in  Epimechus,  Ephelops,  etc.  A remarkable 
character  exists  in  the  subcontiguous  middle  coxje  of  Magdalinops. 
As  will  be  seen  further  on,  considerable  inq)ortance  has  been  attached 
to  the  relative  length  of  the  ventral  segments. 

The  .sexes  can  generally  be  separated  without  much  difficulty  by 
keeping  in  view  the  following  points : 

Ma/e. — Beak  stouter,  more  coarsely  sculptured  and  generally  more 
o})aque ; anteniiie  inserted  nearer  the  aj)ex,  or  more  coi-rectly  sj)eak- 
ing,  the  beak  as  already  pointed  out  by  Jekel  (Annales  de  la  Soc. 
Entom.  de  France,  1864)  is  less  prolonged  beyond  the  insertion  of 
the  antennie,  the  distance  of  the  latter  from  the  base  is  about  equal 
in  both  sexes. 

Female. — Beak  more  slender,  less  coarsely  punctured  and  more 
shining ; anteniue  more  remotely  inserted  from  the  apex. 

The  third  and  fourth  ventral  segments  appear  to  be  a trifle  shorter 
in  the  males  ; the  fifth  is  generally  longer  and  rounded  in  the  female  ; 
shorter,  subtruncate,  or  eniargiuate  in  the  male,  permitting  the  py- 
gidium  to  become  more  or  less  visible  from  below.  The  latter  is 
more  freely  exj)osed  in  the  male,  rarely  entirely  covered  by  the  apex 
of  the  elytra,  while  frequently  only  partially  exj)osed  or  entirely 
concealed  in  the  female.

The  tibial  armature,  and  especially  the  mucro  of  the  posterior 
tibiie,  is  more  slender  and  longer  in  the  male  than  in  the  female. 

As  is  well  known,  all  the  members  of  the  present  tribe  are  phyto- 
phagous, and  the  greater  number,  no  doubt,  spermo])hagous.  A few, 
like  A.  sycophanta,  P.  cratcegi,  Coccotorus,  etc.,  are  said  to  breed  in 
galls.  I regret  that  I have  nothing  new  to  offer  in  the  life-history 
of  these  insects. 


Family  CURCULIONID.E. 

Tribe  Anthonomini. 

Mandibles  bi-emarglnate  and  three-toothed  at  tip;  gular  peduncle 
long  ; oral  organs  small. 

Beak  cylindrical,  long  and  slender;  more  rarely  moderately  stout 
and  shorter  (Macrorhoptus,  some  Anthonomi).  More  or  less  curved 
in  all,  but  nearly  straight  in  Macrorhoptus  and  Cionistes.  Scrobes 
commencing  at  a distance  from  the  buccal  opening  (less  remote  in 
the  subgenus  Paranthonomus) ; straight  or  somewhat  curved ; directed 
against  the  middle  or  lower  segment  of  the  eyes;  more  rarely  (Mac- 
rorhoptus, Cionistes,  Pseudanthonomus  and  Ephelops)  oblique  and 
directed  beneath  the  eyes. 

Antenme  variable,  long  and  slender  in  the  great  majority  ; in- 
serted at  a distance  from  the  apex  ( less  remote  in  Paranthonomus) ; 
subbasal  in  certain  Orchestes  (Alyctus  Thoms.).  Scape  long  and 
slender,  rarely  (Macrorhoptus,  certain  Orchestesj  short  and  stout ; in- 
crassate  at  its  distal  extremity  and  generally  impinging  against  the  eye, 
except  in  Tachypterus  and  those  genera  having  the  scrobes  oblique 
and  directed  beneath  the  eyes.  Funicle  live  to  seven  jointed,  glab- 
rous; first  joint  stout,  generally  elongate;  following  joints  variable, 
each  with  a verticel  of  six  to  ten  stiff  or  flexible  hairs;  rarely 
I Acalyptus  and  Euclyptus)  entirely  pubescent.  Clava  elongate  oval 
or  elliptic,  acuminate,  pubescent;  closely  or  more  loosely  articulate 
(first  joint  strongly  glabrous  in  Magdalinops,  some  Anthonomi  and 
Neomastix),  rarely  very  elongate  and  very  loosely  articulate  (Ta- 
chypterus and  in  the  subgenus  Leptarthrus),  or  broadly  oval  and 
closely  articulate  (Neomastix). 

Eyes  at  least  moderately  large,  roumled  and  remote  from  the  pro- 
thorax ; rarely  (subgenus  Anthonomorphus)  small  and  subrostral  in 
their  position  ; widely  separated  above,  and  nearly  flat  or  moderately 
convex  in  most;  rarely  (A.  elegans,  leucosticfus ; Leptarthrus,  Or-

chedes)  very  prominent,  and  approximate  upon  the  front;  large, 
transver.sely  oval  and  approximate  beneath  in  ]\Iacrorhoptus.  In  a 
number  of  species  the  posterior  margin  of  the  eyes  is  more  or  less 
free  and  elevated,  in  consequence  of  which  its  surface  is  directed 
more  anteriorly. 

Head  more  or  less  rounded  or  conical,  not  deeply  immersed  into 
the  prothorax  (except  Cionistes). 

Prothorax  wider  than  long  (except  A.  brunnipennis) ; narrowed 
in  front;  anterior  opening  obliquely  truncate  (except  Acalyptus). 
Very  rarely  (Macrorhoptus,  subgenus  Anthonomorphus  and  Tricho- 
baropsis)  emarginate  antero-inferiorly  and  giving  a feeble  appearance 
of  postocular  lobes  ; base  bi-emarginate,  produced  in  front  of  the 
scutel ; latter  small,  oval  or  rounded,  densely  pubescent  or  scaly. 

Elytra  variable,  generally  wider  at  the  base  than  the  prothorax  ; 
striato-punctate  (striae  confluent  at  base  in  most  Pseudanthononii). 
The  outer  margin  shows  the  following  variation:  in  those  species 
having  the  elytra  ample,  that  is,  completely  concealing  the  pygidium, 
the  outer  margin  of  one  elytron  forms  a continuous  horizontal  line 
in  its  juxtaposition  with  the  other  and  the  outer  stria  unites  with  the 
sutural  stria  at  an  almost  right  angle.  On  the  other  hand,  in  those 
species  in  which  the  pygidium  is  freely  exjiosed,  the  outer  margin 
of  each  elytron  ascends  towards  the  apex,  forming  an  angle  in  which 
the  pygidium  becomes  more  or  less  visible,  and  the  outer  and  sutural 
strife  unite  at  a more  or  less  obtuse  angle.  In  the  text,  the  term 
dehiscent  has  frequently  been  used  to  denote  the  latter  character, 
which  varies  greatly  in  extent,  being  most  strongly  marked  in  A. 
profimdus,  elegans,  etc.,  and  scarcely  noticeable  in  A.  nebulosus,  pe- 
ninsularis,  etc. 

Prosternum  short  in  front  of  eoxfe  (long  in  Acalyptus,  and  mod- 
erately so  in  Anth.  ipfipes  and  disjunctus).  Anterior  coxte  contigu- 
ous, rather  large  and  prominent ; middle  coxje  separated  liy  the 
mesosternum  (subcontiguous  in  Magdalinops) ; the  latter  generally 
narrow,  very  rarely  (subgenus  Anthonomocyllus)  wider  than  long, 
between  the  coxie.  Metasternum  moderately  long  (short  in  Antho- 
nomocyllus) ; side  pieces  narrowed  posteriorly.  Posterior  coxfe 
widely  separated  (only  moderately  so  in  Magdalinops). 

Ventral  segments  variable  in  length  ; subequal  in  Macrorhoptus, 
Tachypterus,  Magdalinops,  and  some  Anthonomi.  First  and  second 
segments  elongate  (scarcely  elongate,  with  the  first  segment  short 
behind  the  coxie  in  Anthonomocyllus ; very  strongly  elongate  in 


Ts’ORTH  AMERICAN  COLEOPTERA. 


181 


Anthonomopsis).  Third  and  fourth  segments  shorter  than  the  for- 
mer, rarely  (Alycodes,  Elleschus  and  Euclyptus)  very  short.  The 
fifth  segment,  aside  from  sexual  differences  as  noted  before,  attains 
its  greatest  length  in  iVlycodes,  Elleschus,  Euclyptus  and  a few 
species  of  Anthonomus. 

The  sutures  are  straight  and  deep,  except  the  first,  which  is  less 
deeply  impressed  (almost  obsolete  in  Anthonomopsis)  ; the  latter  is 
(aii’ved  in  Elleschus,  Anthonomopsis  and  Euclyptus. 

The  pygidium  varies  in  size ; it  is  oblique  and  concealed  in  both 
sexes  in  Alycodes,  Macrorhoptus,  JMagdalinoj)S,  Tachypterus  and 
Elleschus;  more  or  less  exposed,  at  least  in  the  male  in  all  the  others. 
The  more  perpendicular  its  position,  the  more  freely  exposed  it  be- 
comes. It  is  indexed  in  some  males,  where  it  fits  into  the  emargina- 
tion  of  the  last  ventral  segment ; this  is  most  notably  the  case  in 
Coceotorus,  to  a less  extent  in  Anthonomocyllus  and  Xeomastix.  It 
is  narrowly  excavated  in  a longitudinal  direction  in  the  subgenus 
Paranthonomus. 

Legs  never  very  stout  (except  Nanops)  ; thighs  more  or  less  cla- 
\ ate  and  generally  toothed.  Tibire  generally  slender  ; posterior  of 
male  curved  in  Anthonomocyllus  and  Cnemocyllus ; toothed  inter- 
nally in  A.  elegans  and  Leptarthrus  irroratns.  The  apical  armature 
requires  more  than  a passing  notice.  It  consists  either  of  a hook, 
unguiculum,  arising  from  the  apical  articulating  surface,  curved  in- 
ward at  almost  a right  angle  with  the  tibial  axis,  or  else  a mucro,  a 
prolongation  of  the  internal  apical  angle  into  a point,  in  the  direc- 
tion of  or  approximating  to  the  longitudinal  axis  of  the  tibia.  Being 
morphologically  distinct,  I have  found  differences  in  the  armature 
of  sufficient  importance  to  be  made  use  of  in  the  separation  of 
genera.  The  anterior  and  middle  tibiae  are  unguiculate,  and  the 
posterior  mucronate  in  the  majority  of  genera.  All  are  unguiculate 
in  Alycodes,  Tachypterus,  Magdalinops,  Macrorhoptus,  Chelonychus, 
Anthonomopsis,  Elleschus  and  Nanops.  Acalyptus  has  the  anterior 
and  middle  tibiae  unarmed,  the  posterior  feebly  mucronate,  while  in 
Euclyptus  all  the  tibiae  are  unarmed,  and  in  Xanthus  the  armature 
becomes  very  feebly  developed. 

Tarsi  variable,  never  very  stout  (except  some  species  of  Elleschus)  ; 
frequently  long  and  slender  ; third  joint  bilobed,  spongy  or  pubescent 
beneath,  fourth  joint  generally  of  moderate  length  (short  in  Elles- 
chus, very  long  in  several  species  of  Cnemocyllus).  Claws  somewhat 
approximate  and  armed  with  a large  tooth  in  the  great  majority  ; 


182 


WILLIAM  G.  DIETZ,  M.  D. 


the  tooth  is  either  curved  inward  at  the  apex  and  approximate  to,  or 
else  straight  and  parallel  with  the  tooth  of  the  other  claw.  The 
tooth  is  small  and  inconspicuous  in  a few  Anthonomi  and  Nanops, 
and  especially  so  in  Chelonychus,  where  the  claws  are  also  bent  back- 
ward. The  claws  are  appendiculate,  that  is,  armed  with  a broad  tooth 
beneath  in  Elleschus,  Euclyptus  and  Orchestes,  and  entirely  simple 
and  more  widely  divergent  in  Alycodes,  E])imechus,  Ephelops,  Xan- 
thus  and  Acalyptus. 

The  species  of  the  present  tribe  are  mostly  small  insects,  a few 
almost  minute;  none  in  our  fauna,  at  least,  exceeding  6 mm.,  or  .25 
inch,  in  measurement.*  The  vestiture  consists  of  pubescence  or 
scales.  In  Anthonomoclneta  the  pubescence  is  intermixed  with  erect 
seta?. 

In  conclusion  of  these  introductory  remarks,  I desire  to  express 
my  thanks  to  all  who  have  kindly  permitted  the  use  of  their  material,

The  generic  description  with  the  above  synoptic  reference,  will 
readily  distinguish  this  well-known  species  from  any  other.  A large 
tubercle  is  sitiuited  on  the  third  interspace  on  the  summit  of  the  de- 
clivity, another  on  the  fourth  nearer  the  apex.  There  are  also  some 
irregular  elevations  on  the  filth  and  seventh  interspaces.  The  elytra 
are  ti'ansversely  imiiressed  behind  the  scutellum,  and  this  S])ace  is 
densely  clothed  wdtii  wdiitish  pubescence.  The  pi’othorax  has  three 
narrow'  lines  of  wdiitish  ])ubescence,  wdiile  a lateral  stripe  of  bright 
yellow  pubescence  is  continued  upon  the  densely  pubescent  side

Elytra  distinctly  striate  and  punctured,  leaving  the  pygidunn,  at

This  genus  contains  by  far  the  largest  number  of  species,  which 
vary  greatly,  not  merely  in  their  general  habitus,  but  also  in  more 
important  characters,  possessing  at  least  a subgeneric  value.  I have 
deemed  it,  therefore,  expedient  to  establish  a number  of  subgenera, 
in  in-eference  to  still  further  increasing  the  number  of  those  having 
full  generic  value.  As  will  be  seen,  I have  included  Coccotorus  Lee. 
in  the  present  genus,  as  the  unusually  deep  emargination  ot  the  fifth 
ventral  segment  of  the  S , has  after  all  but  a relative  value,  and 
should  therefore  not  remain  distinct.

The  above  description  has  been  taken  from  a single  S specimen 
in  the  collection  of  Mr.  E.  A.  Schwarz,  who  obtained  it  from  Air. 
Brnuer.  This  appears  to  be  a distinct  species,  hut  having  only  :i 
unique  specimen  for  compai’ison,  larger  series  may  prove  the  above 
characters  to  be  inconstant,  and  therefore  consider  the  matter  still 
sub-judice. 

Subgeniis  Anthonomocyllus. 

This  subgenus  has  for  its  tyjie  A.  elegaus  Lee.  The  beak  is  long 
and  slender,  feebly  curved,  striate  and  carinate.  Antenme  inserted

pinging against  the  eye;  funicle  7-jointed.  Club  not  closely  ar- 
ticulate, .somewhat  shining  and  sparsely  pubescent.  Eyes  convex, 
posterior  margin  elevated,  free.  Head  globose,  punctured  and  pu- 
bescent. Prothorax  convex,  wider  than  long,  and  about  twice  as 
long  above  than  below;  strongly  narrowed  in  front;  base  bisinuate. 
Elytra  wider  at  base  than  the  jirothorax,  broadly  oval  and  very 
convex ; striato-punctate.  Prosternuin  very  short  in  front  of  the 
coxie.  Mesosternum  rather  wide  between  the  coxie,  declivous  in 
front.  Metasternum  short.  Middle  coxie  rather  widely  separated. 
First  ventral  segment  short  behind  the  coxie.  Male:  segments  1-4 
short,  nearly  equal,  fifth  elongate,  about  twice  as  long  as  the  pre- 
ceding and  emarginate.  Female  : segments  subequal,  fifth  mR  elon- 
gate. Pygidium  expensed,  convex  ; indexed  and  more  freely  exposed 
in  the  male,  perpendicular  and  less  exposed  in  the  female.  Legs

the  end  of  a series,  of  which  ^-1.  elegam  forms  the  type,  and  where 
intermediate  forms  are  wanting,  or  at  least  not  represented  thus  far 
within  our  faunal  limits.  All  are  robust,  liroadly  oval  and  very

It  gives  me  itleasure  to  dedicate  this  species  to  my  friend  and  col- 
league, Dr.  J.  Hamilton,  whose  zeal  in  behalf  of  entomology  is  well

Three  specimens;  coll,  of  Dr.  Hamilton.  The  second  ventral 
segment  is  a little  longer  than  the  third  or  fourth,  and  the  fifth  a 
little  shorter  than  the  two  preceding  segments  united.  It  is  closely 
related  to  the  following  species  : 

4.  A.  piisilliis  Lee. — Not  very  unlike  the  former,  from  which  it  differs  in 
the  following  characters;  much  smaller,  more  broadly  oval ; ferruginous  to  pi-

squamous;  fovea  obsolete.  Antennfe  a trifle  stouter;  second  joint  of  funicle 
stout  and  but  a trifle  longer  than  the  third  ; outer  joints  more  distinctly  wider. 
Elytra  more  distinctly  wider  at  base  than  the  prothorax  and  scarcely  longer  than 
wide.  Markings  obscure,  almost  obsolete.  The  tooth  on  the  hind  femur  is 
scarcely  noticeable.  Tihife  feebly  l)isinuate  internally.  The  third  and  fourth 
ventral  segments  are  very  short  in  the  male;  the  second  longer  than  the  first 
behind  the  cox®,  and  the  fifth  as  long  as  the  two  preceding  segments  together. 
In  the  female  the  second  and  fifth  segments  are  about  equal,  the  others  shorter.

Subgenus  Anthonomorphus. 

Distinguished  from  the  other  suhgenera  by  the  eyes,  which  are 
small,  rubrostral  in  their  position  and  somewhat  approximate  upon 
the  front.  The  beak,  which  is  slender,  has  four  grooves  or  deep 
strife,  extending  from  the  base  to  about  the  insertion  of  the  antennte. 
.Scape  of  anteniife  slender  ; funicle  rather  stout,  more  so  in  the  female  ; 
first  and  second  joints  elongate,  joints  3-7  short,  about  as  long  as

A 9 specimen,  received  with  the  foregoing  from  INIr.  H.  Ulke  for 
determination.  It  is  with  some  reluctance  that  I record  this  species 
as  distinct  from  peninsularu,  but  the  strikingly  different  coloration, 
which  is  not  due  to  immaturity,  the  head  not  constricted  hehind  the 
eyes  and  the  deep,  transverse  indentation  above  the  eyes,  seems  to 
warrant  its  separation,  until  more  extensive  series  of  s[)ecimens  shall 
establish  its  identity  with  the  former.

A coarsely  })ubescent  species  from  Texas,  having  the  prosternum 
emarginate  and  the  seventh  joint  of  the  fnnicle  continuous  to  the 
club,  forms  the  type  of  this  subgenns.  The  anterior  and  middle 
femora  are  bidentate,  posterior  with  a single  tooth.  The  tibiae  are 
l)i-emarginate  internally,  and  the  armature  well  marked.  The  tarsi 
are  slender;  claws  broad  and  widely  sejiarate,  armed  with  a tooth

not  free  behind.  Prothorax  conical,  one-third  wider  than  long  and  about  twice 
as  wide  at  the  base  than  at  the  apex ; sides  feebly  rounded  from  base  to  apex, 
latter  not  constricted,  slightly  emarginate;  base  feebly  bisinuate.  Surface  feebly 
convex,  densely  and  coarsely  punctured  and  pubescent;  pubescence  condensed 
along  the  median  line  ; anterior  thoracic  opening  not  oblique,  rather  deei>ly  emar- 
ginate at  its  inferior  margin,  giving  rise  to  the  appearance  of  postocular  lobes, 
which  are  ciliate  with  long,  flying  hairs.  Elytra  oblong,  scarcely  wider  at  the 
base  than  the  prothorax  ; sides  nearly  straight,  parallel  for  two-thirds  their  length, 
gradually  rounded  to  and  feebly  separated  at  tbe  tip,  leaving  the  pygidium  ex- 
posed ; base  straight;  strife  and  punctures  deep  and  rather  coarse  on  the  disc, 
less  so  toward  the  apex;  interspaces  convex,  especially  toward  the  base,  finely 
punctured  ; pygidium  perpendicular.  Legs  slender  ; femora  feebly  clavate,  an- 
terior and  middle  bidentate ; hind  thighs  unidentate;  all  the  tibife  bisinuate 
internally  and  subangulate  above  the  middle.  Tarsi  slender.  Long.  3.25 — 3.75 
mm.;  .1.3 — .15  inch. 

Hab. — Texas. 

In  form  this  species  resembles  somewhat  Trichobaris,  without, 
however,  the  denuded  spots;  through  the  emarginate  prosteruum  and 
the  outer  joints  of  funicle  continuous  to  the  club,  the  |)resent  subgenus 
approaches  Macrorhoptus,  and  through  the  former  also  Anthonomor- 
phus. 


Subgenus  Leptarthrus. 

Under  this  subgeneric  name  I have  separated  from  Anthonomus 
proper  two  new  and  peculiar  species  from  Florida,  in  which  the  an- 
tennal club  becomes  greatly  elongated  and  the  joints  very  loosely 
articulate;  the  beak  is  slender.  Antenme  very  slender,  funicle  7- 
jointed,  with  the  first  and  second  joint  longer  than  the  following 
ones.  Prosteruum  very  short  in  front  of  {'.oxie ; mesosternum  mod- 
erately wide  between  the  coxie.  Ventral  segments  subequal ; first 
and  second  moderately  long,  former  longer  than  the  latter;  seg- 
ments 0 and  4 short,  equal,  or  nearly  so  ; fifth  segment  a little 
longer  than  the  fourth  in  the  male,  and  about  equal  to  it  in  the 
female  ; pygidium  exposed  in  both  sexes ; anterior  legs  longer  and

The  toothed  tibire  distinguish  this  species  from  the  preceding,  and 
in  this  respect  agrees  only  with  A.  elegans.,  from  which  it  is  sufficiently 
distinguished  otherwise. 

A specimen  in  Mr.  Schwarz’s  collection  has  the  elytra  more  uni- 
formly whitish,  with  a few  darker  spots  ; the  alternate  interspaces 
are  a tritle  more  convex,  and  the  tuberosities  on  the  summit  of  the 
elytral  declivity  are  obsolete.  I do  not  consider  it  specifically  dis- 
tinct. 


Subgenus  Paranthonomus. 

This  subgenus,  which  has  for  its  type  A.  profundus  Lee.,  is  readily 
recognized  by  the  deej),  longitudinal  excavation  of  the  pygidium. 

Beak  cylindrical,  rather  slender  and  punctured  ; scrobes  comiuen- 
cing  one-fifth  ( S ) or  one-third  ( 9 ) from  the  buccal  o|>ening,  straight,

vex. Head  conical,  punctured;  front  foveate ; antennre  slender,  in- 
serted less  than  one-quarter  ( S ) or  one-third  ( 9 ) from  the  apex  ;

at  the  base  with  a long,  slender  tooth. 

The  vestiture  consists  of  rather  coar.se,  whitish  pnbe.scence,  which, 
on  the  elytra,  is  intermixed  with  fine,  blackish  hairs. 

The  genus  is  represented  by  three  species  in  onr  fauna,  while  in 
Europe  it  is  represented  by  A.  jjabescens,  and  ])robably  A.  jjyreiioivs. 

Our  sjiecies  may  be  tabulated  as  follows:

As  already  pointed  out  by  LeConte  (op.  cit.  ]).  109),  this  cannot 
lie  A.  he/vohts  Boh.  (Sch.  Gen.  et  Sp.  Cure.  vol.  vii,  2,  p.  224),  as  the 
description  “ feinorihus  anteriorihus  hreviter  unidentatis,  posticis 
muticis,”  and  again,  “Thorax  latitudine  postica  nonnihil  hrevior,” 
does  in  no  wise  correspond  with  the  species  under  consideration. 

Subgemis  Anthonomus. 

I have  hut  little  to  add  to  the  definition  of  the  genus  as  here  re- 
stricted, to  what  has  been  given  in  the  table.  The  fifth  ventral  seg- 
ment of  the  male  is  hut  rarely  emarginate.  The  funicle  is  6-jointed 
in  but  a small  number  of  species. 

The  present  suhgenus  contains  by  far  the  greatest  number  of  spe- 
cies, which  j)resent  structural  differences  of  considerable  importance, 
and  which  I have  made  use  of  in  subdividing  the  species  into  the 
following  groups : 

Funicle  seven-jointed. 

Upper  surface  pube.seeut  (scales,  if  auy,  are  arranged  in  spots  or  lines,  except  A. 
concinnus) ; claws  strongly  toothed. 

Elytra  conjointly  rounded  at  the  apex;  pygidiuin  of  % very  little  exposed; 
pubescence  dense,  arranged  in  patterns  on  the  elytra. 

nebulosus  Group. 

Elytra  not  conjointly  rounded  at  the  apex  ; pygidiuin,  at  least  of  the  male,  more 
fully  exposed  ; pubescence  uniform,  or  condensed  in  spots  or  lines 
without  distinct  patterns. 

Anterior  femora  bidentate gularis  Group. 

.interior  femora  unidentate. 

Third  ventral  segment  longer  than  the  fourth;  fifth  segment  shorter, 
rarely  as  long  as  the  fourth  in  the  male. 

Pubescence  of  elytra  uniform,  rarely  condensed  in  spots  or  lines,  and 
without  denuded  patch  or  fascia.  PI.  vi,  fig.  I4...suturalis  Group. 

Elytra  with  spots  or  lines  of  condensed  pubescence,  enclosing  a denuded 


patch  or  fascia.  PI.  vi,  fig.  15 sig-natus  Group. 

Third  and  fourth  ventral  segments  equal  or  nearly  so;  fifth  segment  of 
male  longer  than  the  fourth.  PI.  vi,  fig.  16....scutellatus  Group. 
Upper  and  lower  surface  pubescent;  claws  armed  with  a small,  inconspicuous 

tooth juniperinus  Group. 

Upper  and  lower  surface  clothed  with  scales;  tarsi  long squamosus  Group. 

Funicle  six-jointed. 

Claws  armed  with  a large,  distinct  tooth subfasciatus  Group. 

Claws  armed  with  a short  basal  tooth ung-ularis  Group. 


nebulosus  Group. 

I have  nothing  fuither  to  add  to  the  description  of  this  group, 
as  given  in  the  synopsis,  except  that  the  tooth  of  the  claws  is  rather

shorter  and  more  obtuse  than  in  the  other  species  with  7-jointed 
funicle,  in  this  respect  resembling  rather  ^4.  pyri,  ulmi,  ornatus,  etc., 
of  Europe.  In  fact,  the  two  species  belonging  here,  one  of  which 
is  introduced  from  Europe,  are  more  characteristic  of  the  fauna  of 
that  continent  than  our  own. 

The  two  species  are  readily  distinguished  as  follows: 

More  robust,  anterior  thighs  bideutate,  pubescence  more  squamiform. 

iiebiilo^iiiis  Lee. 

More  slender,  anterior  femur  with  a large  triangular  tooth,  pubescence  piliforni. 

poiiioriim  Linn. 

\.  iiebiilosiis  Lec. — Oval,  brownish  piceous ; pubescence  dense,  rather 
squamiform  of  a grayish,  brown  or  fawn  color  and  intermixed  with  very  fine, 
short  hairs,  forming  distinct  patterns  on  the  elytra.  Beak  long,  slender,  mod- 
erately curved,  quadristriate,  lateral  striae  deeper  and  longer,  punctured  and 
scarcely  pubescent.  Antennae  inserted  remotely  from  the  apex,  rather  long  and 
slender  ; scape  slender,  paler  than  the  rest;  second  joint  of  funicle  slender  and 
longer  than  the  third ; joints  3-4  slightly  elongate,  longer  than  the  following 
joints.  Eyes  convex,  posterior  margin  free.  Head  convex,  pubescent;  occiput 
more  finely,  front  more  coarsely  and  densely  punctured.  Prothorax  more  than 
one  half  wider  than  long;  sides  more  strongly  rounded  in  front,  strongly  nar- 
rowed anteriorly;  apex  feebly  constricted  and  impressed  at  the  sides  behind  the 
anterior  margin  ; surface  evenly,  densely  and  rather  coarsely  punctured,  rather 
sparsely  pube.scent  with  three  narrow,  paler  lines.  Elytra  one-fourth  wider  at 
the  base  than  the  prothorax,  oblong,  sides  feebly  rounded  and  gradually  nar- 
rowed to  the  tip,  which  is  conjointly  rounded ; strife  impressed,  |iunctures  coarse 
and  rather  closely  placed;  interspaces  convex,  punctulate;  scutellum  white;  the 
pubescence  is  arranged  as  follows : a trapezoidal  basal  space,  a double  curved 
band  commencing  below  the  humerus  and  extending  obliquely  to  the  middle  of 
the  suture,  thence  curving  outward  in  a transverse  direction  to  the  outer  margin  ; 
within  the  space  included  is  another  triangular  area  of  pubescence;  underside 
of  body  and  head  clothed  with  squamiform  pubescence.  Abdomen  less  densely 
and  more  coarsely  pubescent,  pygidium  very  little  ( '^  ) or  not  expo.sed  (f). 
Legs  moderately  stout,  thighs  clavate,  anterior  bidentate,  internal  tooth  lofig, 
outer  tooth  small,  triangular  and  connected  with  the  former  at  the  base.  Tibiae

me  becomes  almost  obsolete,  being  replaced  by  several  serratnres  on 
the  outer  margin  of  the  internal,  or  large  tooth.  This  modification, 
however,  could  not  give  rise  to  confusion  with  the  next  species  in 
which  the  antei  ior  femoral  tooth  is  much  larger,  and  the  external 
margin  perpendicular.  In  the  majority  of  specimens  examined  the 
pygidium  is  entirely  concealed  by  the  elytra.

A female  specimen  of  this  common  European  species  was  received 
some  years  ago  among  specimens  of  nebuloms,  to  which  it  hears  a 
superficial  resemblance.  The  less  robust  form  and  large,  single  tooth 
of  the  anterior  thighs,  will  readily  distinguish  the  present  species. 
It  is  with  some  hesitancy  that  I introduce  this  species  as  occurring 
in  our  fauna,  based,  as  it  is,  on  a unique  specimen. 

g’ularis  Group. 

The  species  belonging  to  this  group  have  the  anterior  thighs  bi- 
dentate,  the  i)ygidium  rather  freely  exposed,  and  the  j)ubescence 
coarse  or  sparse,  without  any  attemi)t  at  forming  distinct  j)atterns.

Whether  the  introduction  of  this  species  into  our  faunal  limits  is 
permanent  or  not,  future  observations  must  decide.  Three  specimens 
are  before  me,  two  in  the  collection  of  Dr.  Horn,*  labeled  Mexico, 
and  a sitecimen  in  INIr.  Schwarz’s  collection  from  Texas.  Thev  tallv

ters as  given  in  the  table.  The  third  and  fourth  ventral  segments 
are  shorter  than  in  the  other  members  of  this  group.

Each  elytron  has  a fnscons  reflection  along  its  disc.  This  species 
could  only  be  confounded  with  the  following,  from  which  it  is  dis- 
tinguished by  the  characters  given  in  the  table.

vated line,  scarcely  attaining  the  base.  Head  opaque,  densely  and  finely  punc- 
tured, front  with  an  imjjressed  line.  Prothorax  rnfo-piceous.  Elytra  bright 
ferruginous,  periscutellar  space  and  along  the  suture  dark  piceons  ; anterior  tibite 
fringed  with  hair  along  the  inner  margin  ; anterior  tibiae  of  male  curved  inward 
near  the  apex,  and  the  internal  angle  produced  in  form  of  a broad  hook.  Legs 
and  abdomen  along  the  middle  ferruginous.  Long.  2.5 — 3.4  mm. ; .10 — .15  inch.

A.  riifipeiiiiiN  Lee. — Of  the  same  general  liahitus  as  gularis,  but  smaller, 
and  the  pubescence  a little  more  pronounced.  It  differs  in  the  following  char- 
acters: Piceous,  elytra  ferruginous.  Beak  shorter  and  stouter,  opaque;  striolate 
with  several  rows  of  remote  punctures,  lateral  elevated  line  more  prominent, 
median  not  extending  u])on  the  front.  Anteunse  pale  rufous,  club  dusky,  second 
joint  of  funicle  elongate.  Eyes  convex,  but  not  free  behind.  Prothorax  scarcely 
one-half  wider  than  long.  Elytra  semi-opaque,  strife  and  punctures  more  strongly 
impressed  ; interspaces  slightly  convex,  finely  rugose,  each  with  several  irregular 
rows  of  punctures  ; scutellar  space  and  along  the  suture  darker;  the  pubescence 
on  the  under  surface  is  white  and  as  dense  as  in  gularis ; the  legs  are  a trifle 
stouter.  Long.  2.2 —3  mm.  ; .09 — .12  inch. 

This  species  varies  somewhat  in  size  and  coloration,  some  speci- 
mens are  entirely  rufous;  the  pubescence,  also,  is  more  pronounced 
in  some  than  in  others. 

LeConte’s  description:  “thorax  a little  longer  than  wide,”  does 
not  correspond  with  any  specimens  before  me,  nor  does  the  statement 
in  his  synoptic  table  of  species — that  the  anterior  thighs  are  uniden- 
tate.  The  smaller,  outer  cusp  is  well  marked  in  all  but  a single 
specimen,  in  which  it  is  nearly  obsolete.

suturalis  Group. 

The  species  belonging  to  this  group  have  the  anterior  thighs  uni- 
dentate.  The  ventral  segments  decreasing  in  length  from  the  second, 
the  third  segment  being  always  longer  than  the  fourth,  and  this  lon- 
ger than  the  fifth,  at  least  in  the  male,  except  corvulus,  where  the 
fifth  is  scarcely  shorter  than  the  fourth  segment.  In  general,  the 
species  are  rather  sparsely  pubescent,  except  suhguttatus,  all  the 
femora  armed  with  a single  tooth  (hind  pair  mutic  in  melancholwm), 
although  the  tooth  of  the  posterior  pair  becomes  nearly  obsolete  in 
specimens  of  siibguttatus  and  mondus.  The  tarsi  are  more  slender 
than  in  the  next  group,  and  the  first  joint  longer  than  the  second; 
the  elytra  are  without  a denuded  fascia  ; lines  and  spots  of  pubes- 
cence do  not  occur,  excejit  in  suhguUatus,  more  rarely  in  flavicortds. 

The  species  are  closely  related,  and  while  it  is  not  difficult  to  rec- 
ognize typical  specimens,  aberrant  forms  occur  whose  exact  position 
it  may  not  be  always  easy  to  determine. 

I have  arranged  the  species  as  follows : 

Entirely  rufo-testaceous  or  ferruginous,  underside  of  thorax  generally  darker. 

Elytra  finely  striate,  punctures  small,  interstices  flat,  wide;  antennae  slender. 

Elytral  interspaces  rugose,  prothorax  not  constricted  at  apex  ; larger  species.

A unique  female  in  my  collection.  It  might  be  confounded  with 
the  preceding  species,  its  nearest  ally,  but  differs  especially  in  size 
and  form  of  prothorax.  From  eonfums  it  is  distinguished  by  the 
much  less  pronounced  elytral  sculjtture  and  the  intersiaices  being

The  three  [treceding  specie.s  are  very  closely  related,  but  more  ex- 
tensive series  are  necessary,  to  prove  them  as  mere  variations  of  one 
species.  Two  specimens  in  Dr.  Horn’s  collection,  from  Montana, 
which  I refer  to  the  present  species,  show  a decided  similarity  to

always  fen-nginons.  The  anterior  thoracic  margin  is  generally  retl- 
dish.  The  legs  are  either  bright  ferruginous,  or  else  pitchy  black, 
without  having  observed  any  intermediate  variations.  One  specimen 
in  Dr.  Horn’s  collection  from  South  California  has  the  elytra!  striae 
rather  supei’ficial  and  the  punctures  smaller.  I have  no  doubt  of 
the  identity  of  this  species  with  A.  h(zmatopus  Boh. 

A.  suturalis  Lee. — Similar  in  size  and  form  to  sycoplianta,  but  a trifle  less 
robust,  pitchy  black,  elytra  more  or  less  ferruginous,  tibim  rufo  piceous,  tarsi 
paler,  the  beak  is  oi>aque,  feebly  striate  and  punctured.  Antenute,  head  and  eyes, 
as  in  that  species.  Prothorax  transverse,  more  stroTigly  rounded  on  the  sides 
behind,  narrowed  in  front,  constricted  and  transversely  impressed  behind  the 
anterior  margin;  surface  more  densely  and  finely  punctured,  base  bisinuate. 
Elytra!  strife  not  strongly  impressed;  punctures  small,  not  verj’  close;  inter- 
stices flat,  more  shining  and  very  finely  rugose;  scutellum  clothed  with  white 
pubescence  ; under  surface  as  in  that  species,  but  the  pubescence  is  a little  more 
dense  and  squamiform  ; the  tibite  are  a little  stouter,  the  tarsi  longer,  and  the 
claws  larger;  the  tooth  of  the  latter  is  also  a little  larger.  Long.  2.7— 3 mm. ; 
.11 — .12  inch. 

Hub. — Eastern  and  Western  States. 

The  red  apical  blotch  varies  greatly  in  extent,  leaving  always, 
however,  the  suture  and  scutellar  space  black.  Larger  sized  speci- 
mens with  the  elytra  almost  entirely  red,  may  be  confounded  with 
A.  virgo,  from  which  the  present  species  differs  by  its  nnidentate  an- 
terior femora,  more  strongly  elavate  thighs  and  smooth  rostral  carina. 
Fi-om  sycophanta  it  is  to  be  distinguished,  aside  from  coloration,  by 
the  sides  of  the  ])rothorax  being  more  strongly  rounded  and  the 
apical  constriction,  the  punctures  also,  are  less  coarse  and  less  dense, 
and  the  elytra  more  shining. 

A specimen  in  Dr.  Horn’s  collection  from  Iowa,  while  evidently 
belonging  to  the  present  sjiecies,  has  the  ])rothorax  quite  coarsely, 
though  very  closely,  punctured.  The  elytra  are  entirely  ferruginous, 
with  a triangular  basal  space  dusky.

Two  males  and  one  female,  collected  by  my  friend,  F.  H.  Wickham,

<)n  account  of  the  squamifonn  pubescence,  which  is  readily  removed, 
this  species  might  he  referred  to  the  sqnamosus  group,  with  which, 
however,  it  has  not  the  least  affinity.  Abraded  specimens  resemble 
more  nigrinm,  from  which  it  differs  by  the  finely  punctured  protho-

J[ab. — Southern  States  (Patiii  ?). 

A specimen  in  my  collection,  taken  in  this  neighborhood  (Hazleton, 
I’a.),  measures  scarcely  2.5  mm.,  but  does  not  differ  otherwise.  Two 
specimens  from  Texas  in  Mr.  Hike’s  collection  are  a little  less  robust, 
with  tw'o  interrujjted  lines  of  condensed  pubescence  on  the  elytra, 
thereby  forming  some  similarity  to  subguttahis.  From  nigriuus,  witii 
which  the  present  species  might  be  confounded,  it  is  to  be  distin- 
guished by  the  less  coarsely  and  less  densely  |)unctured  prothorax, 
testaceous  antennie  and  less  slender  legs. 

A.  inoriiliis  Lee. — Black,  or  piceou.s,  robu.st  and  convex;  pubescence  fiue, 
sparse,  a trifie  more  dense  on  the  under  surface.  Beak  moderately  slender, 
punctured,  shining  towards  the  apex,  median  carinate  line  distinct,  feebly 
striate  from  the  base.  Auteniife  rather  robust,  rufo-piceous;  scape  and  first  joint 
of  funicle  rufous,  second  joint  of  funicle  longer  than  the  third,  joints  3-7  trans- 
verse, outer  joints  wider.  Eyes  feebly  convex  and  scarcely  free  behind.  Head 
globo.se,  occiput  scarcely,  front  more  distinctly  punctured ; frontal  ]mncture 
rather  large;  a transverse,  impressed  line  on  a level  with  the  superior  margin 
of  the  eyes.  Prothorax  scarcely  one-half  wider  than  long,  moderately  narrowed 
anteriorly,  scarcely  constricted  at  the  apex  ; sides  almost  straight  behind,  feebly 
rounded  before  the  middle,  base  not  bisinuate;  surface  coarsely  and  rather 
densely  punctured.  Elytra  about  one-third  and  rather  suddenly  wider  at  base 
than  the  jirothorax  and  less  than  one-half  longer  than  wide ; the  sides,  seen  from 
above,  appear  slightly  emarginate  behind  the  humerus,  due  to  a feeble  bulging 
outward  of  the  ninth  and  tenth  interspaces,  rather  suddenly  nai-rowed  to  the 
apex,  which  is  separately  rounded  and  widely  dehiscent,  leaving  the  f)ygidiuin 
freely  exposed  ; striae  fine,  punctures  moderately  large  and  approximate;  inter- 
spaces flat,  suhopaque  and  rather  strongly  rugose;  under  surface  ]iunctulate.

Hah. — California. 

Only  two  female  specimens  in  Dr.  Horn’s  collection  are  before  me. 
Bears  a striking  resemblance  to  Eprinechm  viwiicus,  described  further 
on,  from  which,  indeed,  it  cannot  be  distinguished,  except  by  the 
toothed  claws. 

Since  writing  the  above  I have  received  a specimen  from  Dr.  Horn, 
which  has  entirely  the  coloration  of  a typical  A.  snturalls,  the  elytra 
being  bright  rufous  with  the  exception  of  a triangular  basal  space ; 
it  is  easily  recognized,  however,  by  the  form  of  the  jirothorax  and 
the  le.ss  shining  elytra. 

A.  corvnlus  Lee. — Rather  robust,  oval,  black  shining:  pubescence  rather 
long  and  coar.se,  but  sparse  and  easily  removed.  Beak  moderately  slender,  punc- 
tured with  well-marked  median  carina ; scrobes  curved,  somewhat  ap])roximate 
beneath  and  directed  against  the  lower  angles  of  the  eyes.  Anteniife  stout,  rufo- 
piceous;  scape  paler,  second  joint  of  fuuicle  scarcely  longer  than  the  third, 
following  joints  gradually  wider,  verticels  consisting  of  stiff,  bristle-like  hairs. 
Eyes  feebly  convex  and  slightly  free  behind.  Head  convex,  occiput  impunc- 
tured,  front  with  a few  punctures  and  a well-marked  fovea.  Prothorax  trans- 
verse, more  than  one-half  wider  than  long,  strongly  rounded  on  the  sides  and 
gradually  narrowed  to  apex,  which  is  feebly  constricted  ; base  scarcely  hisinuate, 
surface  coarsely,  hut  not  densely  punctured.  Elytra  about  one-fourth  wider  at 
the  base  than  the  prothorax  ; humeri  rounded  ; sides  a little  widened  to  behind 
the  middle,  separately  rounded  at  tip,  leaving  the  pygidium  freely  exposed  ; striae 
deejdy  impressed,  wide:  punctures  large,  not  closely  approximate : interspaces 
convex,  smooth,  with  small,  remote  punctures:  scutellum  white  jmbescent: 
underside  remotely  punctured,  pubescence  more  dense.  Legs  .slender,  thighs 
feebly  clavate,  all  armed  with  a small,  acute  tooth  : tibiae  almost  straight,  and  at 
the  apex,  like  the  tarsi,  brownish.  Long.  1.5 — 2.2  mm. : .06 — .09  inch. 

Hah. — Pennsylvania,  Massachusetts,  District  of  Columbia,  Illinois, 
W isconsin,  Michigan,  Texas,  Arizona. 

Easily  recognized  by  its  small  size,  shining  black  color,  coarsely 
punctured  prothorax  and  s])arse  pubescence.  The  pubescence  is 
easily  rubbed  off,  giving  the  insect  a still  more  shining  appearance, 
and  on  sujierficial  examination,  might  give  rise  to  confusion.  Speci- 
mens are  before  me  of  a brown  color,  probably  due  to  their  being 
immature.

wise closely  allied  to  Jlavicornis,  from  which  it  differs  in  the  following  charac- 
ters: Pubescence  coarse,  dense  and  white.  Beak  more  slender  and  shining, 
finely  and  less  closely  punctured  : median  carina  more  distinct,  shining,  and  ex- 
tending to  the  frontal  puncture.  Head  not  concentrically  rugulose,  second  joint 
of  funicle  scarcely  longer  than  the  third.  Prothorax  less  rounded  on  the  sides, 
which  are  almost  straight  behind  with  the  hind  angles  rectangular:  apex  not 
constricted,  punctures  smaller  and  remote  on  the  disc,  crowded  on  the  sides:  a

enclosed  between  these  lines  is  not  denuded,  densely  clothed  on  the  underside 
with  white  ])ubescence;  pygidium  freely  exposed.  Legs  slender,  rufo-piceous.

tibim  scarcely  bisinnate  internally.  Long.  2.7  mm.  ; .11  inch. 

Hub.  — Florida,  District  of  Columbia. 

A specimen  in  Mr.  Dike’s  collection,  from  District  of  Columbia, 
differs  from  the  typical  form  by  the  pubescence  being  jiale  yellowish, 
sparser  and  less  coarse. 

This  species  might  jiossibly  be  referred  to  the  signatus  group,  with 
which,  however,  it  has  no  close  relationshiji ; the  first  and  second 
ventral  segments  are  relatively  shorter,  and  there  is  no  denuded 
elytral  fascia.  Dr.  LeConte  indicated  this  species  under  A.  scutella- 
tus  Gyll.  ( Proc.  Amer.  Phil.  Soc.  vol.  xv,  p.  Uh)),  hut  failed  to  de- 
•scrihe  it. 

sig-natus  Group. 

This  group  contains  species  of  rather  small  size,  and  presenting  a 
similarity  of  habitus  which  makes  them  easy  of  recognition.  They 
agree  with  those  of  the  preceding  group  in  the  abdominal  formation; 
the  first  and  second  ventral  segments,  however,  are  genei’ally  longer 
and  nearlv  ecjual  in  length,  the  gradual  decrease  in  length  commen- 
cing with  the  third  segment,  instead  of  the  second,  as  in  that  grouii. 
The  elvtra  have  a post-median  denuded  patch  or  fascia,  surrounded, 
in  the  fresh  state  at  least,  by  spots  or  lines  of  pubescence.  They 
difier  very  little  in  sculpture,  and  are  to  be  distinguished  rather  by  a 
general  assenddage  of  characters  and  habitus.  The  first  two  tarsal 
j(dnts  are  equal,  or  nearly  so. 

The  following  table,  supplemented  by  the  Sjiecific  description,  will 
enable  the  student  to  identify  his  species: 

Elytral  interspaces  equal,  or  nearly  so.

Frontal  fovea  small,  punctiform  ; pubescence  fine,  inconspicuous. 

Elytra  reddish,  scutellar  space  and  fascia  darker,  latter  interrupted  on

strongly  rounded,  feebly  constricted  at  the  apex  and  transversely  impressed 
behind  the  anterior  margin;  surface  rather  coarsely  and  densely  punctured, 
pubescence  condensed  along  the  median  line.  Elytra  less  than  one-fourth  wider 
at  the  base  than  the  prothorax  and  about  one-half  longer  than  wide,  a little 
widened  to  behind  the  middle;  sides  feebly  rounded  ; strife  impressed,  punctures 
moderately  large,  close  set  and  becoming  smaller  towards  the  lateral  margin  ; 
inter.spaces  slightly  convex,  shining  with  an  irregular  row  of  fine  punctures; 
the  denuded  fascia  extends  from  the  side  to  the  third  interspace,  another  de- 
nuded spot  on  the  second  interspace  ; scutellar  space  and  along  the  suture  darker  ;

Hub — Atlantic  slope. 

Varies  considerably  in  size,  and  still  more  so  in  coloration,  from 
pale  testaceous  to  almost  pitchy-black  ; the  latter  variation  might 
readily  be  mistaken  for  the  next  species,  from  which  it  differs  by  the 
less  rounded  prothorax  and  stouter  antennal  funicle ; the  beak  also 
is  more  densely  punctured  and  less  curved.  The  following  variety 
is  well  marked,  and  deserves  special  consideration  :

pectus  infuscate.  Prothorax  nearly  twice  as  wide  as  long  ; the  scn- 
tellar  space  is  scarcely  darker.  I rvould  consider  this  to  be  bislff-

Differs  from  signatus  by  its  coar.se  ])ubescence,  larger,  elongate 
frontal  fovea  and  uniform  brown  color  ; the  elytral  fascia  is  wider, 
extending  hirther  anteriorly,  and  is  not  interrupted. 

Dr.  Hamilton’s  specimen  has  the  jtrothorax  more  finely  and 
densely  jtnnctured,  and  the  posterior  thighs  not  toothed.  It  may 
possiblv  be  distinct,  but  as  it  agrees  otherwise,  I do  not  feel  justified 
in  establishing  a new  sjiecies  on  a single  specimen.

Varies  in  coloration  ; fresh  specimens  have  the  elytra  more  bright 
red,  which  in  dried  specimens  changes  to  a dark  brown  or  even 
blackish  color.  The  denuded  spot  can  generally  be  recognized  by 
its  darker  color,  and  being  surrounded  by  a line  of  pubescence, 
which  is  liable,  however,  to  abrasion.  Why  Prof  Riley  should  con- 
sider this  species  identical  with  sir/natus  (Agric.  Report  1885,  pp. 
276-282)  I cannot  understand,  for,  aside  from  the  difference  in  length 
of  the  second  joint  of  funicle  which  is  always  evident  in  fresh  and 
can  be  demonstrated  on  old  specimens  that  have  been  relaxed,  the 
]>resent  species  is  less  robust,  thorax  less  rounded  on  the  sides,  and 
suture  always  darker.  According  to  Dr.  John  Hamilton  it  is  rarely 
found  after  the  first  week  in  June,  whereas  signcdus  is  found  always 
during  the  whole  of  Summer  on  various  plants  and  shrubs,  while 
the  former  is  generally  tidcen  on  Huckleberry.

Similar  in  size  and  habitus  to  corvulm,  from  which  it  difiers  by 
the  prothorax  being  more  strongly  rounded  on  the  sides  and  less 
coarsely  punctured,  the  denuded  elytral  fascia  and  the  tarsi  shorter

resemltles  in  appearance,  it  difiers  by  its  smaller  size,  shorter  and 
relatively  stouter  beak  and  shorter  tarsi ; the  first  two  joints  of  the

readily  he  distinguished  hy  tlie  shorter  beak  and  tarsi,  and  the  second 
joint  of  funicle  distinctly  longer  than  the  third. 

Comparison  with  the  type  of  this  species,  in  the  LeConte  collection 
at  Cambridge,  was  kindly  made  by  Dr.  G.  H.  Horn.

This  species  greatly  resembles  rufipennis  of  the  gidaris  group,  but 
is  smaller,  and  differs  further  by  the  front  being  sidcate,  the  anterior 
thighs  with  a single  tooth  and  the  posterior  thighs  mntic. 

The  ffrst  two  ventral  segments  tire  relatively  shorter  in  this  than 
the  other  species  of  this  group,  and  the  spots  of  condemsed  pubescence 
on  the  elytra  give  it  a peculiarly  striking  appearance.

nigrinus  Group. 

The  species  of  this  grouji  difler  from  those  of  the  two  jireceding 
ones  by  the  fifth  ventral  segment  of  the  male  being  longer  than  the 
fourth,  the  third  and  fourth  equal  in  length,  or  very  nearly  so.  In 
some  specimens  the  fifth  ventral  is  not  longer  than  the  fourth  ; in 
this  case,  however,  the  third  and  fourth  are  always  equal  and  shorter 
than  in  the  two  preceding  groups. 

The  species  are  closely  related,  and  are  to  be  distinguished  as 
follows : 

All  the  tliigbs  armed  with  a single  tooth. 

Black  ; front  foveate. 

Robust;  anterior  and  middle  tibife  curved  inward  near  the  apex  ; first  joint

rather  conspicuously  clothed  with  wdiite  pubescence,  which  is  more  dense  on  the 
under  surface.  Beak  long  and  slender,  feebly  (uirved,  punctured,  scarcely  striate. 
Antennse  long  and  slender,  .scape  and  first  joint  of  funicle  rufo-testaceous,  re-

wider  at  the  base  than  the  prothorax;  oval,  sides  feebly  rounded;  striae  im- 
pressed, punctures  round,  small  and  closely  approximate;  interspaces  slightly 
convex,  each  with  about  three  irregular  rows  of  fine,  piliferous  punctures;  pu-

.14  inch. 

Hab. — Lower  California;  exact  locality  not  stated. 

A % and  9 specimen  in  Mr.  Dike’s  collection,  who  received  it 
very  recently  from  the  above  locality. 

The  mesosternum  is  moderately  wide  between  the  coxte,  where  it 
ends  in  an  elevated,  transverse  ridge,  and  slojtes  very  gradually  in 
front.  The  third  and  fourth  ventral  .segments  are  of  e(jual  width, 
and  the  fifth  distinctly  longer  than  either ; the  pygidium  is  freely 
visible  from  below. 

This  species,  although  very  distinct,  is  closely  allied  to  fiavicornis, 
nigrinns  and  albopiloms.  It  resembles  fiavicornis  so  closely  that,  if 
viewed  from  above,  it  cannot  be  distinguished,  except  by  its  somewhat 
greater  size ; the  abdominal  formation,  however,  is  strikingly  different, 
the  beak,  legs  and  tarsi  much  more  slender;  the  first  j'oint  of  the 
anterior  tarsi  twice  as  long  as  the  second,  while  equal  in  fiavicornis. 
From  the  next  species  it  differs  by  its  being  more  robust,  the  beak 
more  slender,  thorax  less  coarsely  punctured,  the  femoral  tooth  spini- 
form, the  anterior  and  middle  tibim  curved  near  the  aj)ex,  and  the 
more  slender  tarsi  with  the  first  joint  nearly  twice  the  length  of  the 
.second.  The  elytra,  also,  are  a little  more  strongly  striato-punctate, 
and  the  ]nibescence  much  more  conspicuous  than  in  that  species.

Not  unlike  ftavicornis,  from  which  it  differs  in  the  abdominal  for-

Might  also  be  confounded  with  morulus,  but  is  more  robust  and  le.ss

A very  distinct  species,  differing  from  the  preceding  by  its  longer 
and  denser  pubescence,  the  anterior  tihire  curved  near  the  liase,  the 
large  anterior  femoral  tooth,  and  also  its  more  slender  form. 

The  fifth  ventral  segment  is  twice  as  long  as  the  fourth  ; the  j)y- 
gidium  remotely  punctured,  pubescent  in  the  male,  glabrous  in  the 
female.

This  species  has  been  confounded  \v\th  fiavicornis,  from  which  it  is 
easily  di,stinguished,  aside  from  structural  difterenees,  by  the  colora-

The  pubescence  being  rather  coarse,  squainiforin,  this  species 
might  be  placed  among  those  of  the  squamosvs  group,  with  which, 
however,  it  agrees  less  in  habitus  than  those  of  the  present  group. 
One  specimen  from  Oregon  has  the  posterior  thighs  obsoletely  toothed

cover any  other  material  difference.  It  resembles  ^4.  murinus,  but  is

This  species  is  an  exact  reproduction  of  A.  ungularis  in  form,  color 
and  pubescence,  but  for  the  7-jointed  funicle,  absence  of  elytral 
fascia  and  very  slender  tooth  of  claw,  it  could  not  possibly  be  dis- 
tinguished. The  fifth  ventral  segment  is  longer  than  the  preceding.

This  species,  at  once  recognized  by  its  pale  testaceous  color  and 
dark  elytral  spot,  has  a remarkable  similarity  to  Nanophyes  trans- 
verms  Aube  of  Southern  Europe,  and  which,  according  to  Desbro- 
(‘liers,*  was  described  by  Chevrolat  as  Anthonomus  juniperi. 


squamosus  Group. 

Contains  all  those  species  with  7-jointed  funicle,  in  which  both  the 
upper  and  under  surface  are  ])redominantly  clothed  with  scales. 
The  scaly  vestiture,  while  dense  in  most  of  the  species,  is  sparse  and 
intermixed  with  a fine  pubescence  in  some.  The  scales  also  vary 
from  almost  round  to  very  elongate,  piliform.  The  ventral  segments 
are  less  unequal  than  in  the  majority  of  the  pubescent  species.  Some 
of  the  vittate  forms  shoAV  great  similarity  to  the  species  of  the  sub- 
genus Cnemocyllus,  from  which  they  differ  merely  by  the  hind  tibise 
of  the  male  not  being  dissimilar  from  those  of  the  female. 

The  species  may  be  tabulated  as  follows  : 

Stout  species  ; all  the  femora  armed  with  a tooth. 

Anterior  thoracic  opening  very  oblique,  prosternum  short  in  front  of  the  coxai. 
Elytra  without  transverse,  partly  denuded  fascia.

Closely  allied  to  squamosus,  from  which,  indeed,  it  ditiers  but  little 
structurally,  excejit  in  the  form  and  density  of  the  scales.  Comjiarison 
will  show  at  once  that  it  should  not  be  placed  among  the  pubescent 
species.

grayish  white,  or  pale  yellowish,  oval  scales;  otherwise,  like  the  preceding  spe-

follows:  Beak  reddish  brown,  more  shining,  less  punctured  and  scarcely  striate. 
Prothorax  more  distinctly  wider  than  long.  Elytra  scarcely  one-fourth  wider 
than  the  prothorax  at  its  base,  humeri  more  oblique;  striae  and  punctures  more 
concealed  by  the  scales.  Legs  reddish  brown.  Long.  3.5  4.5  mm.;  .14 — .18  inch. 

Hab.  -Kansas,  Colorado,  New  Mexico,  California,  Nebraska. 

Varies  considerable  in  form,  coloration  and  density  of  the  scalv 
vestiture.  The  alternate  elytral  intersjiaces  are  paler  in  some  speci- 
mens, giving  them  a vittate  appearance,  more  or  less  marked. 

Two  variations,  deserving  sjiecial  mention,  occur: 

Var  a. — Scales  uniformly  grayish  white,  less  closely  adherent  to 
the  derm.  Each  elytral  interspace  with  an  irregular  row  of  suberect, 
setae-like  hair.

The  identification  of  this  species,  which  was  donbtful  from  the

Might  easily  be  mistaken  ^ovhirtm;  in  fact,  the  descriptive  phrase, 
as  given  by  LeConte  of  that  species,  “ densely  clothed  with  coarse, 
scarcely  squamiform,  ochreous  jtubescence,”  a|)plies  far  better  to  the 
sjtecies  under  consideration  ; it  is,  however,  less  elongate,  the  eyes 
slightly  encroaching  u|)on  the  front,  the  prothorax  distinctly  wider 
than  long,  the  thighs  more  strongly  clavate,  and  both  anterior  and 
middle  armed  with  a tooth.  The  peculiar  curved  projection  of  the 
terminal  hook  of  the  anterior  and  middle  tibise  I do  not  remember 
of  having  observed  in  any  other  sj)ecies.  One  of  the  specimens  has 
a strongly  marked,  oblique  impression  each  side  of  the  jirothorax. 
The  unusual  occurrence  of  this  kind  of  sculpture  in  the  present 
tribe  is  no  doubt  due  to  some  disturliance  in  the  earlier  stages.

The  following  variety  deserves  special  mention : Larger  and 

darker;  frontal  fovea  sulciform,  deeply  impressed;  the  scaly  vesti- 
ture  more  consjiicuous  ; scutellum,  scntellar  and  intra-humeral  sjiots 
very  densely  scaly.  Long.  2.7  mm.;  .11  inch.  Occurs  in  District 
of  Columbia,  Florida,  Texas,  Pennsylvania. 

Subgenus  Cnemocyllus. 

Under  this  subgeneric  name  I have  included  all  those  species 
which  have  the  posterior  tibite  dissimilar  in  the  two  sexes,  those  of 
the  male  being  more  or  less  curved,  while  in  the  female  they  are 
straight,  or  nearly  so.  This  curvature  varies  greatly,  being  most 
marked  in  ornatulus  and  figuratus,  and  least  in  Ugatns.  The  fifth 
ventral  segment  is  more  or  less  elongate,  except  in  sabvittatus,  or- 
natulus and  jiguratus,  and  very  long  in  inermis.  The  tarsi  are  never 
short  and  broad,  but  are  very  long  and  slender  in  a few  sj)ecies. 
The  tooth  of  claw  varies  considerably  in  development.  The  form 
varies  from  oval  to  elongate,  and  the  integument  is  clothed  with 
scales,  which,  in  most  of  the  species,  form  lines  or  vittae  after  a com- 
mon pattern,  as  follows:  A pale  line  on  the  fourth  interspace  com- 

mencing about  the  middle  and  variable  in  extent,  another  vitta  on 
the  sixth  interspace  commencing  at  the  base  and  extending  to  about 
the  middle;  in  addition  to  these  there  is  in  some  a darker  patch  or 
fascia  on  the  sides  behind  the  middle.  The  prothorax  is  generally 
vittate ; the  funicle  of  the  antemue  is  either  6-  or  7-jointed. 

The  species  occur  in  the  Western  and  Southern  States,  are  closely 
related,  and  require  great  care  to  be  distinguished.  The  following 
table,  sujiplemeuted  by  the  descri|)tions  and  figures  given,  will,  how- 
ever, enable  the  student  to  positively  identity  them.

A female  specimen  in  Dr.  Horn’s  and  a male  specimen  in  my 
collection.  A very  distinct  species,  not  unlike  dark  colored  speci- 
mens of  pauperculus,  from  which,  however,  it  is  distinguished  aside 
from  structural  differences  by  its  bright  ornamentation,  more  trans- 
verse thorax,  elongate  second  joint  of  funicle,  very  long  tarsi  and 
short  tooth  of  claw.  For  differentiation  from  figuratm  the  student 
is  referred  to  that  species. 

.A.  u.  sp.  Plate  vi,  figs.  21,  21ffl. — Very  similar  in  form,  color  and 

vestiture  to  the  preceding,  but  a little  larger,  and  the  scales  less  closely  applied 
to  the  derm,  and  therefore  more  easily  removable;  the  beak  a little  longer  and 
more  robust  at  the  base,  with  the  sculpture  more  pronounced  ; the  eyes  are  placed 
more  laterally ; the  prothorax  hut  little  wider  than  long,  with  the  punctures 
smaller  and  more  crowded  ; the  elytral  strife,  denuded  of  the  scaly  vestiture,  are 
fine,  but  well  impressed,  becoming  wider  and  deeper  near  the  base  ; the  ])uuctures 
small  and  closely  apiiroximate  ; interspaces  nearly  flat,  except  at  the  hase,  punc- 
tured and  somewhat  rugose;  the  coloration  is  almost  identical,  but  less  sharply 
defined,  the  broad  white  stripe  dissolved  into  two  vittfe.  Legs  a little  darker, 
thighs  infuscate  about  the  middle;  tibife  longer,  anterior  more  bisinnate  inter- 
nally and  the  posterior  of  male  even  more  strongly  curved  than  in  that  species;

Three  males  are  liefore  me;  one  well-preserved  specimen  in  Mr. 
Schwarz’s  collection  and  two  aln'aded  ones  from  Santa  INIonica,  L. 
Cal.,  in  mine.  The  fifth  ventral  of  the  male  is  a little  longer  than 
the  fourth. 

.4,  iiieriiii!^  Boh.  Plate  vi,  fig.  22. -Elongate-oval,  ferruginous,  densely 
clothed  above  and  beneath  with  large,  broadly  oval,  white,  or  grayish  white 
scales.  Beak  moderately  long  and  slender,  curved  and  scarcely  pubescent;  three 
elevated  lines  from  base  to  juiddle,  with  corresponding  strife  between  ; scaly  at 
the  base.  Antennae  rather  stout,  second  joint  of  funicle  not  longer  than  the 
third;  club  dusky.  Eyes  feebly  convex,  posterior  margin  slightly  free.  Head 
punctured  and  densely  scaly,  frontal  fovea  elongate.  Prothorax  longer  than 
wide,  narrow'ed  in  front;  sides  rounded,  feebly  constricted  at  the  apex  and  trans- 
ver.sely  impressed  behind  the  anterior  margin,  closely  and  rather  finely  imnc-

Hah. — California. 

I am  not  at  all  certain  about  the  identity  of  this  species,  as  Le- 
Conte  describes  the  thighs  as  being  unarmed.  I have  only  four 
specimens  before  me,  in  all  of  which  the  tooth  of  the  anterior  pair 
is  discernible,  but  it  is  quite  possible  that,  on  account  ot  its  small 
size,  it  had  been  overlooked  by  that  author.  Two  specimens  in  Dr. 
Horn’s  collection  have  the  upper  surface  somewhat  mottled  with 
brownish  scales. 

A.  jacobiiius  n.  sp. — Oblong-elliptic,  ])iceous,  antennae  and  legs  ferrugin- 
OU.S,  densely  clothed  above  and  beneath  with  moderately  large,  whitish  scales. 
Beak  not  very  slender,  feebly  but  regularly  curved,  opaque  ( % ),  or  somewhat 
shining  (9),  indistinctly  carinate  and  .striate;  scrobes  straight.  Antennae 
slender,  inserted  two-lifths  ( '^  ) or  one-half  { 9 ) from  the  apex,  funicle  6-jointed, 
first  joint  not  very  robust,  elongate;  second  joint  longer  than  the  third.  Eyes 
feebly  convex,  scarcely  free  behind.  Head  wide,  and  like  the  beak  at  base, 
densely  scaly,  irregularly  puuctulate  ; frontal  fovea  small,  punctiform.  Pro- 
thorax a trifle  wider  than  long,  moderately  narrowed  in  front,  but  scarcely  con- 
stricted at  the  apex,  sides  nearly  straight  behind  the  middle,  teebly  emarginate 
each  side  at  base  ; surface  densely  and  rather  coarsely  punctured  ; scales  more 
condensed  along  the  middle  and  on  the  sides.  Elytra  a little  wider  at  the  base 
than  the  prothorax  ; sides  nearly  parallel  for  one-half  their  length,  thence  grad- 
nally  rounded  to  apex,  which  is  moderately  dehiscent;  striaj  wide,  impressed, 
punctures  large,  rounded,  and  not  closely  approximate;  interspaces  convex, 
rugulose;  scales  a little  more  condensed  on  the  basal  third  of  the  sutural  and 
sixth  interspace;  underside  of  body  densely  punctured.  I..egs  moderately  slen-

3.5  mm. ; .14  inch. 

Hab. — Colorado. 

A male  and  female  specimen  in  my  collection  only  very  recently 
received.  This  species  resembles  camis  very  closely  in  form  and 
coloration  ; it  differ.s,  however,  by  its  greater  size,  smaller  and  more 
densely  placed  scales,  the  elytra  more  gradually  rounded  to  the  apex, 
the  pygidium  more  freely  exposed,  and  the  hind  tihite  of  the  male 
strongly  eurv'ed  ; the  fifth  ventral  segment  is  longer  than  the  pre- 
ceding in  both  sexes,  esjtecially  the  female. 

A.  rtocipieiis  Lee. — Elongate-oblong,  pitchy-brown,  antennaj  and  legs  fer- 
ruginous, densely  clothed  above  and  beneath  with  large,  oval,  grayish  white 
scales,  which,  however,  on  the  abdomen  become  piliform.  Beak  long,  curved  and 
moderately  slender,  shining,  rather  coarsely  punctured  near  the  base,  three  ill- 
defined,  elevated  lines.  Antennae  somewhat  stout,  second  joint  of  funicle  elon- 
gate, slender  and  longer  than  the  third,  which  is  a trifle  longer  than  the  fourth, 
club  dusky.  Eyes  almost  flat,  posterior  mai'gin  .slightly  free.  Head  convex, 
punctured  and  densely  squamose;  an  impressed  frontal  line  extending  upon  the 
base  of  the  rostrum.  Prothorax  one-third  wider  than  long,  sides  feebly  rounded, 
subparallel  behind,  strongly  narrowed  and  distinctly,  though  not  suddenly  con- 
stricted at  the  apex  ; surface  densely,  though  not  coarsely  itunctured,  indistinctly 
trivittate.  Elytra  a little  wider  at  the  base  than  the  prothorax,  oblong-oval, 
almo,st  parallel  on  the  sides,  gradually  rounded  to  apex  behind,  coarsely  sti  iato- 
punctate,  striae  broad  and  deep,  punctures  large,  oblong  and  closely  approximate  ; 
interspaces  convex,  roughened  ; with  the  scaly  covering  intact,  the  latter  appear 
wide  and  flattened,  and  the  striae,  and  punctures  not  entirely  concealed.  Legs 
moderate,  femora  feebly  clavate,  anterior  feebly  toothed  ; tibiae  slender,  anterior 
and  middle  slightly  bisinuate  internally,  posterior  of  male  regularly,  but  not 
strongly  curved  ; tarsi  slender.  Long.  2 — 2.2  mm. ; .08— .09  inch. 

Hab. — Texas,  Kansas,  Oregon,  Washington. 

The  pygidium  is  more  or  less  freely  exposed,  and  the  fifth  ventral 
segment  longer  than  the  fourth  in  both  sexes,  though  more  markedly 
so  in  the  male,  while  it  is  foveate  in  the  female.  In  well-marked 
specimens  a j^osterior  pale  vitta  on  the  fourth  and  an  anterior  one  on 
the  sixth  interspace,  as  well  as  a post-scutellar  line  are  more  con- 
spicuous ; the  darker,  lateral  space  is  generally  ill-defined. 

Lee.— Closely  allied  to  the  preceding  species;  elliptic.  ]>itchy- 
browu,  densely  clothed  with  very  large,  broadly  oval,  and  uniformly  white 
scales;  it  differs  as  follows:  Beak  more  slender  and  shining,  more  finely  sculp- 
tured, slightly  widened  and  somewhat  depressed  at  the  apex.  Prothorax  but 
little  wider  than  long,  regularly  rounded  from  base  to  apex,  latter  not  constricted. 
Elytra  more  broadly  rounded  on  the  sides;  strise  and  punctures  still  coarser; 
punctures  more  transverse  and  very  narrowly  separate.  Legs,  especially  the

.08 — .10  inch. 

Hab. — Arizona,  California,  Texas. 

The  pvgidiuin  is  but  little  exjiosed  in  the  male  and  entirely  con- 
cealed in  the  female.  The  remarkably  large  scales  ajipear,  under  a 
moderate  magnifying  [)0\ver,  slightly  concave. 

A.  afliilis  Lee. — Of  the  same  form  and  coloration  as  canus,  but  a trifle 
smaller;  the  second  and  third  joints  of  funicle  a trifle  elongate,  equal  in  length  ; 
the  scales  are  smaller  in  size;  tibise  more  slender,  and  the  posterior  of  the  male 
regularly  curved.  Long.  2 — 2.3  mm. ; .08 — .09  inch. 

Hab. — Texas,  Arizona,  New  Mexico,  California. 

The  pygidium  is  more  freely  exposed  in  both  sexes;  fifth  ventral 
segment  markedly  longer  than  the  fourth,  es])ecially  in  the  male. 

A.  iiaiiiis  Lee. — Elongate,  suhparallel ; black,  legs  rufous,  clothed  with 
rather  large,  grayish  white  scales.  Beak  long  and  stout,  curved,  shining,  with

scape  and  basal  joint  of  funicle  reddish,  rest  of  antennae  darker,  piceous,  second 
and  third  joints  of  funicle  somewhat  elongate,  equal  in  length.  Eyes  nearly  flat- 
not  at  all  free.  Head  convex,  coarsely  punctured  and  densely  squamous,  frontal 
fovea  small.  Prothorax  a little  wider  than  long,  scarcely  narrowed  in  front  and 
not  constricted  at  the  apex  ; base  bisinuate,  sides  feebly  rounded  ; surface  densely 
punctured  and  .squamous.  Elytra  elongate,  but  little  wider  at  the  base  than  the 
prothorax,  sides  scarcely  rounded,  broadly  rounded  at  the  apex;  striae  coarse, 
punctures  large  and  rather  remote;  intersiiaces  convex,  rugulose.  Legs  moder- 
ately stout,  thinly  scaly  ; anterior  femora  more  strongly  clavate,  middle  and  pos- 
terior scarcely  at  all;  tibiae  slender,  almost  straight,  posterior  of  male  moder- 
ately and  regularly  curved  ; tarsi  and  claws  as  in  the  preceding.  Long.  1..5 — 1.7 
mm. ; .06 — .07  inch. 

Hab. — Arizona,  New  Mexico. 

The  fifth  ventral  segment  of  male  is  scarcely  one-half  longer  than 
the  fourth  and  of  about  equal  length  in  the  female.  The  pygidium  is 
freely  exposed  in  the  male  and  not  at  all  in  the  female. 

A.  eloiigatii!i»  Lee.  Plate  vi,  tigs.  23,  23a. — Strongly  elongate,  nearly  par- 
allel, pitchy-brown,  clothed  with  large,  rounded,  pale  brown  and  whitish  scales. 
Beak  moderately  long  and  slender,  curved,  subojjaque  and  a little  widened  from 
base  to  apex;  median  carina  distinct,  substriate  each  side.  Antenuse  slender, 
rufo-testaceous,  funicle  6-jointed,  second  and  third  joints  subequal;  joints  4-6 
oblong,  club  darker.  Eyes  feebly  convex,  posterior  margin  free.  Head  slightly 
convex,  punctured  and  scaly,  front  with  impressed  line.  Prothorax  convex,

predominantly  white,  condensed  each  side  of  the  scutellum,  along  the  base  and 
on  the  sixth  interspace  from  base  to  near  the  middle,  the  posterior  denuded  fascia 
almost  reaches  the  suture,  and  is  surrounded  by  a broad  stripe  of  white  scales, 
including  a short  white  line  on  the  fourth  interspace.  Legs  slender,  ferrugin-

Dr.  Horn,  who,  in  this  instance  also,  has  kindly  made  the  com- 
parison with  the  type  in  the  LeConte  collection  at  Cambridge,  has 
found  the  funicle  to  consist  of  only  six  joints  and  not  seven,  as  erro- 
neously stated  by  LeConte,  and  which  had  led  me  to  doubt  the 
identity  of  the  present  species  with  the  one  described  by  LeConte. 

This  species  is  very  closely  related  to  the  following,  with  which  it 
has  heretofore  been  confounded  in  collections.  A specimen  from 
Jacksonville,  Fla.,  in  Mr.  Schwarz’s  collection,  I refer,  with  some 
doubt,  to  the  present  species;  it  has  the  beak  a little  shorter  and 
stouter,  the  second  joint  of  funicle  a little  shorter  than  the  third, 
outer  joints  wider  ; the  elytra  a little  wider  at  the  base  and  not  wider 
posteriorly,  sides  feebly  rounded,  punctures  close  set  and  somewhat 
transverse,  interspaces  more  roughened,  and  the  anterior  femora 
more  strongly  clavate ; it  is  entirely  denuded  of  scales. 

A.  li$;atiis  n.  sp.  Plate  vi,  figs.  24,  24«,  246. — Very  closely  resembles  elon- 
gatus  in  form,  sculpture  and  coloration,  and  is  distinguished  from  that  species  by 
the  following  characters : the  second  and  third  joints  of  the  funicle  are  a little 
more  slender  and  of  nearly  equal  length  ; the  prothorax  more  strongly  rounded 
at  the  sides  and  more  narrowed  anteriorly.  Elytra  not  wider  at  the  base  than 
the  prothorax  with  the  sides  a little  more  rounded  ; the  scales  are  of  a more 
yellowish  color  instead  of  the  white,  and  less  easily  removed,  the  markings  less 
marked  ; the  dark  denuded  fascia  extends  from  the  sides  to  about  the  fourth 
interspace  ; the  tibiae  are  more  slender  and  the  posterior  of  the  male  simply 
emargiuate  along  the  internal  margin  and  entirely  straight  in  the  female.  Long.

A unique  female  specimen  in  INIr.  Schwarz’s  collection.  Very 
tli.stinct;  differs  from  the  two  preceding  species,  to  which  it  is  most 
closely  related,  in  form,  and  in  the  claws  being  armed  with  a long, 
slender  tooth,  in  this  it  agrees  with  subvittatus,  which  it  also  resem-

second  joint  of  funicle  longer  than  the  third. 


Subgenus  Anthonomochaeta. 

Beak  long  and  rather  slender,  curved  and  slightly  widened  beyond

Aside  from  the  v^estiture,  so  unusual  in  the  present  tribe  of  rhyn- 
chophorous  coleoptera,  the  jn-esent  subgenus  differs  from  Anthonomus 
jiroper  by  its  rather  small  eyes  and  the  feeble,  tiliial  armature.  It 
is  represented  by  a single  species. 

A.  lieterogeiins  u.  sj). — Robust,  ovate,  ferruginous  to  ])iceous,  antenuse  and 
legs  rufous;  pubescence  ashy  gray,  concealing  the  sculpture;  the  erect  bristles 
are  arranged  in  a single  row  on  each  elytral  interspace  and  also  along  the  outer 
margin  of  the  tibiae,  giving  them  a fimbriate  appearance.  Beak  ferruginous,

The  imbescence  is  easily  rubbed  off.  'fwo  specimens  taken  early 
in  the  Spring  by  Dr.  Hamilton,  and  kindly  sent  me  for  examination, 
are  entirely  deprived  of  pubescence,  probaldy  due  to  hibernation, 
the  occurrence  of  which  must  be  rare  among  the  members  of  the 
present  tribe. 

PSEmAlVTHOXOitlllS  gen.  nov. 

Beak  rather  stout,  moderately  long  and  curved;  scrobes  oblique, 
directed  beneath,  rarely  {craUegl,  valiclus)  against  the  lower  extremity 
of  the  eye.  Anteniue  not  very  slender,  inserted  two-fifths  ( S ) or 
one-half  ( 9 ) from  the  apex  ; scape  incrassate  at  its  distal  extremity  ; 
funicle  6-,  rarely  (rellctus)  5-jointed  ; fourth  joint  (third,  relictvs) 
shorter  and  smaller  than  eithei'  of  the  preceding  or  following  joints 
(except  briinneus,  parvulus) ; club  loosely  articulate,  pubescent. 
Eyes  variable.  Head  subspherical,  punctured.  Prothorax  wider 
than  long,  bisinuate  at  base,  narrowed  in  front  and  constricted  at  the 
apex.  Elytra  transversely  impressed  behind  the  base  ; strise  and 
punctures  coarse  and  deep;  scutellum  densely  |nibescent;  proster- 
num short  in  front  of  the  coxie;  mesosternum  narrowed  behind; 
metasternum  moderately  long;  ventral  segments  nearly  equal,  fifth 
a little  longer  than  the  fourth  in  the  female ; pygidium  exposed, 
middle  coxie  narrowly,  posterior  not  very  witlely  sejiarated.  Legs 
slender,  femora  feebly  clavate,  all  toothed  ; tibiie  slender,  anterior 
and  middle  unguiculate,  posterior  mucronate  at  apex  ; tarsi  slender, 
claws  armed  with  a long  and  slender  tooth. 

The  species  are  all  of  a rufo-testaceous  or  ferruginous  color  and 
pubescent,  both  on  the  upper  and  under  surface,  without  any  scales. 
In  all,  except /ocefa, 9,  the  first  and  .second,  third  and  fourth,  fifth  and 
sixth  elytral  striie  become  confluent  at  the  base,  the  interspaces  thus 
enclosed  do  not  reach  the  basal  margin,  the  third  interspace  becomes 
wider  and  more  prominent  at  the  anterior  extremity  (except /cicebw). 

The  species  reseiidile  each  other  very  closely,  are  difficult  to  dis- 
tinguish, and  are,  with  the  exception  of  cratcegi  and  incipiens,  rep- 
resented by  a single,  or  but  a few  specimens. 

They  are  to  be  distinguished  as  follows :

This  species  has  heretofore  been  confounded  in  collections  with 
P.  cratcegi,  to  which,  indeed,  it  bears  a close  resemblance,  but  aside 
from  the  diHerence  in  the  direction  of  the  scrobes  it  differs  by  its

is  scarcely  yellow.

A single  female  specimen  is  before  me.  It  is  very  closely  related 
to  bnumens,  with  which  it  agrees  in  the  formtition  of  the  antenme, 
but  differs  in  size,  the  less  convex  eyes  and  the  more  coarsely  punc-

intersjiaces  more  shining.

A unique  S taken  by  me  some  years  ago.  The  occurrence  of 
5-jointed  funicle  in  the  present  genus  is  certainly  remarkable.  In 
general  appearance  the  species  resembles  incipiem ; the  color  is  darker 
than  in  any  other  species. 

\KO.n\STIX  ^en.  uov. 

This  new  genus  is  established  upon  two  small  species  from  the 
Atlantic  States,  differing  from  Anthonomus  in  the  5-jointed  funicle 
and  the  broadly  ovate,  antennal  club. 

Beak  long,  not  very  slender,  |)unctured  and  striate;  scrobes  com- 
mencing near  the  middle  and  directed  against  the  lower  segment  of 
the  eyes.  Antennae  slender,  scape  straight,  moderately  incra.ssate  at 
its  distal  end;  funicle  5-jointed,  first  joint  long  and  robust,  joints  2- 
5 nearly  equal,  outer  joints  a little  wider,  clava  broadly  oval,  closely 
articulate,  basal  joint  shining.  Eyes  moderately  convex  and  slightly

more  distinctly  constricted  behind  the  apical  margin,  and,  like  the

points  from  the  other  members  of  this  genus;  the  claws,  though 
simple,  are  less  slender  and  less  divergent,  the  lobes  of  the  third  tarsal

The  simple  claws,  covered  pygidiiim  and  short  third  and  fourth  ven- 
tral segments,  may  be  considered  valid  reasons  for  placing  it  near 
Erirrhinns.  The  formation  of  the  antenme  and  the  general  habitus 
are  distinctly  Anthonomid.  It  forms  a transition  from  the  present 
tribe  to  the  Erirrhinini.

I captured  my  specimen  ( S ) some  years  ago  on  oak,  and  has  served 
as  the  type  of  the  above  description.  One  of  Dr.  Horn’s  specimens 
agrees  in  all  particulars  (except  sexual  differences)  with  mine,  while 
the  other  has  the  denuded  fascia  of  less  extent  and  the  interspaces 
not  denuded  near  the  base. 

I have  made  careful  comparison  with  well  authenticated  specimens 
of  this  species  from  Europe,  and  can  discover  no  difference,  except 
that  a small  denuded  spot  each  side  of  the  thorax  is  wanting  in  our 
specimens,  but  as  this  also  occurs  in  one  of  my  European  specimens, 
it  is  probably  of  but  subordinate  value.

Mr.  Thos.  Casey  very  kindly  has  sent  me  a typical  specimen  of 
his  E.  callforuicus.  It  is  entirely  pitchy-black,  resembling  in  this 
respect  rather  bipunetatus ; legs  a trifle  paler.  The  beak  is  less 
punctured,  shining,  and  the  second  joint  of  the  funicle  is  longer  than 
the  third.  In  all  other  respects  it  agrees  with  ephippiatus,  from 
which  it  does  not  appear  specifically  distinct,  but  forms  a marked 
variety.

Two  specimens,  male  and  female,  in  Dr.  klorn’s  collection.  A 
very  distinct  species  and  unmistakable  members  of  the  present  genus. 
The  rather  slender  beak  and  toothed  femora  are  anomalous. 

ORC'IIEXTEN  111. 

The  eyes  clo.sely  approximate  above  and  the  saltatorial  })o.sterior 
femora  make  the  recognition  of  the  species  of  this  genus  an  easy 
matter.  "J'he  beak,  variable  in  length  and  thickness,  lies  between 
the  anterior  legs  during  repose  : the  scrobes  commencing  about  the 
middle  or  even  near  the  base;  scape  of  anteniue  not  long  ; funicle 
6-  or  7-jointed.  The  prothorax  is  relatively  small.  The  elytra  oval 
or  elongate-oval,  wider  than  the  prothorax,  with  the  humeri  rounded. 

In  reviewing  the  species  I shall  give  only  sufficient  descriptive 
matter  which,  in  connection  with  the  synoptic  table,  will  enable  the 
student  to  identify  his  material.  To  the  species  heretofore  known  I

Black,  antennse  and  tarsi  rufous;  anterior  elytral  fascia  narrower  than  in  ephip- 
piatus,  about  one-third  from  the  base,  irregular,  prolonged  along  the  sutural  in- 
terspace to  the  scutellum  in  front  and  extended  along  the  second  interspace 
posteriorly,  but  not  connected  with  the  posterior  transverse  hand  which  is  nar- 
row and  angulated.  Long.  2.5  mm.;  .10  inch. 

Hab. — California,  Wisconsin. 

This  is  0.  subhirtus  Horn.  Careful  comparison  of  Dr.  Horn’s 
types  with  specimens  of  the  European  species  in  my  cabinet  leave 
no  doubt  of  their  identity. 

O.  iiiger  Horn. — Rather  robust,  subovate ; black,  anteniife  piceous,  clothed 
with  short  pubescence,  which  is  black  on  the  upper  and  whitish  on  the  under 
surface;  scutellum  densely  white  pubescent;  an  inconspicuous,  transverse  fascia 
about  one-third  from  the  base  and  consisting  of  sparse  white  pubescence.  Long. 
2.8  mm. ; .11  inch. 

Hab. — Illinois,  Michigan,  Pennsylvania. 

The  white  scutellum  is  in  striking  contrast  with  the  rest  of  the 
su  rface. 

O.  pai'vic'ollis  Lee. — Entirely  black,  oblong-oval  with  scarcely  any  lustre. 
Prothorax  coarsely  and  rather  densely  punctured ; hind  angles  subrectangular, 
somewhat  rounded.  Elytral  interspaces  very  rough.  Long.  2.8 — 3 mm. ; .11 — 
12  inch. 

Hub. — California,  Nevada,  Colorado. 

Distinguished  from  the  three  preceding  species  by  the  absence  of 
elytral  markings  and  from  the  following  by  its  coarse  sculpture, 
rounded  posterior  angles  of  thorax  and  the  ninth  elytral  interspace 
not  produced  in  a sjiine.

species.  Black,  thinly  pubescent:  antennae  aud  legs  rufous:  hind  femora  feebly 
incrassate,  more  or  less  piceous.  Long.  2 mm. : .08  inch. 

Closely  allied  to  the  European  0.  foliorum  Miiller,  from  which  it 
appears  to  differ  by  the  prothorax  being  a little  more  transverse  and 
not  rounded  in  front. 

O.  minutus  Horn  is  a variety  of  the  above  with  the  legs  entirely 
piceons.  It  occurs  in  California  and  Colorado. 

XA\TIIUS  gen  . nov. 

I have  established  this  new  genus  upon  two  very  small,  testaceous 
and  thinly  pubescent  species  having  the  claws  simple,  divergent,  aud 
the  tibiae  almost  truncate  at  the  tip,  with  the  armature  very  small. 
Beak  long,  rather  slender  and  nearly  straight,  a little  widened  to- 
wards the  tip,  not  striate  ; scrobes  straight,  attaining  the  eyes,  which 
are  convex.  Antenme  moderately  stout,  inserted  two-fifths  ( S ) or 
one-half  ( 9 ) from  the  apex  ; scape  slender,  impinging  against  the 
eye  ; funicle  7-jointed,  first  joint  stout,  second  and  third  nearly  equal, 
outer  joints  transversely  rounded  ; club  rather  loosely  articulate  ; 
front  sulcate.  Prothorax  wider  than  long,  feebly  narrowed  in  front 
and  slightly  constricted  behind  the  anterior  margin.  Elytra  a little 
wider  at  the  base  than  the  prothorax,  striate  and  punctured ; me- 
sosternum  moderately  wide  between  the  coxie,  declivous  in  front : 
first  and  second  ventral  segments  moderately  long,  third  and  fourth 
shorter,  equal  ; fifth  not  longer  than  the  fourth  in  the  male  ; py- 
gidium  freely  exposed  in  both  sexes.  Legs  moderately  slender, 
thighs  feebly  clavate  ; tibiae  straight,  slightly  widened  towards  the 
tip ; anterior  and  middle  with  a very  small,  scarcely  perceptible 
hook,  posterior  feebly  mucronate  at  apex  ; tarsi  with  the  third  joint 
broadly  bilobed  ; claws  simple. 

The  two  species  are  amongst  the  smallest  in  the  tribe  and  are 
distinguished  as  follows : 

Larger,  rufo-testaceous ; prothorax  more  densely  pimctured,  ])ubescence  con- 
spicuous  

Smaller,  pale  testaceous:  jirotborax  remotely  punctured,  pubescence  very  fine.

WILLIAM  G.  DIETZ,  M.  D. 


The  type  of  this  genus  is  a small  testaceous  insect  without  close 
relationship  in  any  direction,  except,  perhaps,  Acalyptus,  with  which 
it  agrees  in  the  somewhat  flattened  thorax,  unarmed  tibioe  and  the 
formation  of  the  funicle.  It  agrees  with  Alycodes  and  Elleschus  in 
the  abdominal  formation  and  appendiculate  claws,  but  the  fifth  ven- 
tral segment  is  very  long,  and  it  is  very  different  in  other  respects. 

E.  tesf  sicens  n.  sp.  Plate  vii,  figs.  39,  39a,  39b,  39c. — Elliptic,  testaceous, 
almost  glabrous.  Beak  shiuiug,  with  a few  remote  punctures.  Prothorax  rather 
closely  and  finely  punctured,  with  an  ill-defined,  smooth  dorsal  line  extending 
from  the  anterior  margin  to  about  the  middle.  Elytral  striie  impressed,  punc- 
tures moderate,  close  set;  interspaces  scarcely  convex,  slightly  roughened  ; under 
surface  remotely  punctulate.  Long,  nearly  2 mm. ; .07  inch. 

iTa6.— Buffalo,  N.  Y. 

A unique  9 in  niy  collection.  Easily  recognized  by  its  pale  color, 
ventral  formation,  unarmed  tibise  and  apj)endiculate  claw’s.  In  ap- 
pearance it  resembles  Notolomus  basalis,  without,  however,  the  dark 
basal  spot  of  the  elytra.

The  species  of  .4GRIL.ITS  of  Boreal  America. 

- BY  GEORGE  H.  HORN,  M.D. 

The  first  attempt  at  a comparative  study  of  our  species  was  made 
by  Dr.  LeConte  in  his  “Revision  of  the  Buprestidie  of  the  United 
States  (Trans.  Amer.  Philos.  Soc.  xi,  1859),”  in  which  thirty-two 
species  wei’e  recognized  and  eight  previously  described  enumerated 
as  unknown.  In  this  essay  we  find  an  important  use  of  the  form  of 
the  claws  as  the  basis  of  a primary  division  of  the  genus  in  groups. 
Singularly  the  study  of  the  claws  was  carried  no  further,  owing 
probably  to  the  small  material  which  furnished  the  basis  of  the 
work.  It  is  also  to  be  regretted  that  but  little  attention  was  paid  to 
the  sexual  characters,  and,  as  if  by  accident,  only  an  occasional 
allusion  is  made  to  the  form  of  the  prosternal  lobe.  Of  the  thirty- 
two  species  described,  twelve  were  represented  by  single  examples, 
and  of  the  remaining  twenty  nearly  half  were  represented  by  not 
more  than  two.  While  this  condition  rendered  the  study  at  the  time 
easy  and  satisfactory,  the  further  accumulation  of  material  makes  it 
absolutely  necessary  to  refer  to  the  types  for  determination. 

In  1873  (Proc.  Acad.  Nat.  Sci.  Phil.),  Mr.  G.  R.  Crotch  attempted 
a brief  review  of  our  species,  which  is  notable  for  the  insufficiency 
of  his  comments  in  one  portion  of  the  paper  and  the  numerous  inac- 
curacies throughout,  especially  in  the  analytical  table.  The  value 
of  the  Carina  of  the  pygidium  was  first  recognized  in  his  paper,  and 
some  attempt  made  to  use  the  sexual  characters  as  a means  of  sepa- 
rating the  species. 

The  species  of  the  regions  to  the  south  of  our  limits  have  been 
studied  b}^  Mr.  Waterhuuse  (Biol.  Cent.  Amer.  vol.  ii,  pt.  1 ) with 
fairly  good  results,  but  the  species  of  that  region  are  so  entirely 
different  from  our  own  in  facies  and  depend  for  their  separation  on 
characters  not  applicable  in  our  fiuina,  that  his  work  has  been  of  no 
assistance  in  the  preparation  of  this.  In  this  essay  Mr.  Watei-house 
has  separated  one  of  our  species  (pulchellus),  which  has  an  equivalent 
in  Mexico,  from  Ar/rilas  under  the  name  Engyaulus,  but  for  reasons 
which  will  be  found  under  our  species,  the  genus  is  not  considered 
well  founded. 


278 


GEO.  H.  HORN,  M.  I). 


The  species  described  by  Gory  are  barely  recognizable,  and  the 
figures  give  but  little  aid.  He  seems  not  to  have  known  of  the 
species  described  by  Say,  or  else  purposely  disregarded  them. 

It  being  veiy  evident  that  the  unsatisfactory  work  ])reviously  done 
with  our  species  w'as  due  to  insufficient  material,  and  the  neglect  of 
an  examination  of  the  sexual  characters,  no  attemi)t  has  been  made 
by  me  to  record  my  observations  until  reasonably  full  series  had  been 
obtained  with  the  sexes  of  each  species  represented.  In  the  following 
pages  but  one  species  is  represented  by  a single  specimen,  and  of 
about  four  others  two  of  each  have  been  examined. 

As  a general  rule,  our  species  are  .not  marked  by  any  great  surface 
irregularities,  such  as  deej)  thoracic  depressions  and  strongly  elevated 
elytral  costte.  The  only  exceptions  aie  cavaius  and  Couesii,  the 
former  being  represented  in  Mexico  and  the  other  may  also  be.  At 
ti])  the  elytra  are  simjdy  acute  or  rounded,  never  divergent,  and 
variously  formed  as  in  many  of  the  INIexican  species.  The  colors 
are  never  very  brilliant,  nor  is  the  ornamentation  by  pubescent  spots 
very  striking.  The  monotonous  aspect  of  our  species  has  com])elled 
a search  for  structural  characters  wdth  very  encouraging  results,  for 
with  such  characters,  the  limits  of  species  may  be  more  accurately 
defined  notwithstanding  any  variation  which  may  occur. 

In  order  that  the  systematic  portion  of  this  work  may  be  the  better 
understood,  the  various  portions  of  the  body  showing  important 
modifications  will  be  reviewed  consecutively. 

Antenna.  —The  form  of  these  organs  seems  to  have  been  entirely 
neglected.  In  some  species  the  antenme  are  slender  and  long  (PI. 
viii,  figs.  ]1-13),  in  others  short  and  comparatively  stout  (PI.  viii, 
figs.  12-14),  in  the  former  case  the  joints  are  longer  than  wide,  and 
in  the  latter  as  wide,  or  even  wider  than  long.  The  most  im])or- 
tant  modification  observed  is  in  the  mode  of  their  serration.  By 
far  the  larger  number  of  our  species  have  the  antennce  serrate  be- 
ginning wdth  the  fourth  joint  (PI.  viii,  figs.  11,  12);  in  the  others 
the  serration  begins  at  the  fifth  joint  (PI.  viii,  figs.  13,  14).  There 
may  be  at  times  a (juestion  wdth  those  who  study  this  character  for 
the  first  time  and  in  some  species  it  might  be  difficult  to  determine 
to  which  series  it  should  be  referred,  but  whenever  the  fourth  joint 
resembles  the  fifth  more  nearly  than  it  does  the  third,  the  species 
belongs  to  the  first  series,  but  when  the  third  and  fourth  joints  are 
similarly  cylindrical  then  the  species  belongs  to  the  second  series.

Head. — The  front  may  be  flat,  moderately  convex,  or  very  con- 
vex. In  the  latter  case  the  month  seems  more  retracted  and  inferior, 
as  will  be  observed  in  the  sjiecies  from  jmlchelhis  to  muticus,  but  va- 
rying in  degree,  so  that  this  character  fails  to  be  useful  foi’  generic 
separation.  In  nearly  all  the  species  the  head  has  a median  im- 
])ressed  line  beginning  at  the  occiput,  but  this  varies  both  in  extent 
and  depth,  forming  in  several  sj)ecies  a deep  frontal  depression  or 
even  concavity.  The  clypeus  varies  somewhat  in  form,  but  not  to 
the  extent  observed  in  Chrysobothris,  so  that  no  use  has  been  made 
of  it  in  the  table.  Sexually  the  head  varies  in  sculpture  and  coloi', 
as  will  be  found  recorded,  but  the  differences  between  the  sexes  are 
not  by  any  means  as  well  marked  as  in  Chrysobothris,  or  in  the  more 
closely  allied  Anthaxia.  Other  characters  of  more  resti-icted  oc- 
currence will  be  found  under  the  species  in  which  they  occur. 

Prothorax. — The  usual  thoracic  characters  based  on  color,  sculp- 
ture and  the  depressions  require  no  S{)ecial  comment.  The  carina  of 
the  hind  angles  has  nearly  always  been  mentioned  from  the  earliest 
descriptions,  and  its  presence  or  absence  regarded  as  an  infallible 
sign  of  specific  distinction.  It  remains  now  to  be  recorded  that  in  a 
number  of  species  the  presence  or  absence  of  the  carina  is  often 
purely  sexual,  the  male  being  without  it.  This  is  well  shown  in  a 
series  of  acutipennis.  In  all  cases  the  presence  or  absence  of  carina 
must  not  be  assumed  to  be  of  specific  value,  except  when  accompanied 
by  other  characters. 

The  lateral  marginal  edge  of  the  thorax  assumes  two  forms  when 
viewed  from  the  side,  the  sinuate  and  straight.  The  former  is  the 
more  usual,  and  is  well  illustrated  by  macer  (PI.  viii,  fig.  9),  while 
the  straight  form  is  mostly  seen  in  the  cylindrical  species,  such  as 
lacndris,  etc.  (PI.  viii,  fig.  10). 

Prosternum. — The  prosternal  lobe  varies  in  length  and  form, 
sometimes  almost  entirely  concealing  the  mouth.  Its  anterior  margin 
may  be  broadly  rounded  as  in  cavatm  (in  which  the  mouth  is  nearly 
concealed),  truncate  as  in  bllineatus,  or  emarginate,  as  is  the  more 
usual  occurrence.  Various  forms  of  emargination  will  be  observed, 
the  most  irregular  being  in  difficilis,  in  which  the  notch  is  small,  and 
on  each  side  there  is  a sinuation. 

The  tip  or  apex  of  prosternum  is  subject  to  great  modification.  In 
many  species  the  tip  is  continuous  with  the  intercoxal  portion  and 
enters  the  metasternum  by  a triangular  notch,  while  in  others  the 
tip  is  abruptly  bent  upwards  and  enters  the  metasternum  concealed. 


280 


GEO.  II.  HORN,  M.  D. 


This  structure  has  been  well  described  by  Mr.  Waterhouse.  When 
the  tip  of  the  prosternuni  is  closely  applied  to  the  metasternum,  the 
portion  of  the  ape.x  not  concealed  assumes  various  forms,  being  tri- 
angular, rounded,  truncate  or  dilated  (see  muticus  and  species  near). 
For  convenience  of  expression  in  the  analytical  table,  the  visible  free 
portion  has  been  assumed  to  be  the  tip,  and  is  so  spoken  of  in  the 
table. 

SciTTEEEUM. — The  two  forms  observed  are  charactei’ized  by  the 
presence  or  absence  of  a transverse  carina.  This  structure  seems  to 
have  been  considered  as  invariable  as  the  angular  carina  of  tli,e 
thorax,  but  in  several  of  our  species  the  carina  may  be  distinctly 
jiresent  in  some  specimens  and  entirely  absent  in  others. 

Elytra. — In  nearly  all  of  our  species  the  sides  of  the  elytra  are 
slightly  sinuate  behind  the  humeri,  and  then  more  or  less  dilated 
before  finally  narrowing  to  the  aj)ex  (PI.  viii,  fig.  7),  but  in  many 
others  the  elytra  narrow  from  the  luuneri  to  the  apex  almost  without 
sinuation  as  in  difficilis  (PI.  viii,  fig.  8).  In  the  former  case  the  sides 
of  the  abdomen  are  much  less  visible  from  above  than  in  the  latter. 
As  a rule  the  elytra  are  narrower  in  the  male.  The  disc  is  not  often 
costate  and  then  only  in  the  species  of  the  tropical  ty[ie,  as  in  Couesii, 
cavatns  and  macer,  but  in  very  many  species  there  is  on  each  elytron 
a very  vaguely  indicated  costa. 

The  surface  sculpture  is  practically  the  same  in  type  in  all  our 
species,  and  is  derived  from  a form  described  as  imbricated,  resem- 
bling, when  magnified,  a series  of  pointed  tiles,  closely  placed,  in 
which  the  points  are  somewhat  elevated.  The  sculpture  in  s’ome 
species  might  be  described  as  closely  mucronate. 

The  apices  of  the  elytra  are  not,  in  any  of  our  species,  provided 
with  the  curious  prolongations  and  modifications  seen  in  the  tropical 
forms.  The  tip  is  rarely  very  acute  {nevadensis) , usually  rounded. 
The  edge  is  usually  serrulate,  and  in  a few  species  entirely  sim[)le 
(jmdicus,  etc.). 

PvGiDiUM. — In  very  nearly  all  our  species  the  pygidium  is  pro- 
vided with  a median  smooth  or  elevated  line,  in  many  species  forming 
(piite  a ridge,  and  in  a good  number  the  ridge  is  ])rolonged,  forming 
a spine  sometimes  emarginate  at  its  apex  {macer).  The  presence  or 
absence  of  the  prolongation  is  one  of  the  most  constant  of  the  struc- 
tural characters,  although  specimens  of  rnficolUs  are  occasionally 
seen  without  it.  The  pvgidium  oi pulchellm  is  acute  at  tip,  the  carina 
well  marked,  but  not  independently  projecting.

Abdomen. — The  principal  modifications  of  the  abdomen  are  due 
to  sexual  pecnliarities  of  the  male,  which  are  sufficiently  described 
under  the  species  in  which  they  occur.  Several  pecnliarities  have 
been  observed  which  are  not  sexual.  In  ventralis  the  middle  of  the 
posterior  edge  of  the  second  segment  is  free  and  prolonged  slightly 
over  the  next  segment ; the  same  is  observed  in  the  third  segment, 
but  in  a less  degree.  The  sides  of  the  last  ventral  segment  are  nsnally 
simple,  but  in  a few  species  (obolinm,  Wahinc/liami)  the  edge  is  dis- 
tinctly serrulate.  The  apex  of  the  segment  is  rounded  or  oval,  ex- 
cept in  a few  species  (conciniins,  acutipennis),  in  which  it  is  truncate. 
In  iiiine  of  our  species  is  the  last  ventral  emarginate,  as  in  many 
European  species. 

Along  the  side  of  the  abdomen  there  will  be  observed  a well  ele- 
vated ridge,  which  is  sometimes  interrupted  on  the  first  or  second 
segments,  usually  more  or  less  sinuous  in  front.  Although  variable 
within  certain  limits  it  is  not  sufficiently  so  to  warrant  any  use  of  it 
in  the  grouping  of  species.  This  line  divides  the  ventral  segments, 
so  that  the  upper  jiortion,  usually  sub-elytral,  has  been  called,  for 
conveidence,  the  “vertical  ])ortion  of  the  segments;”  it  is  often  dif- 
ferently clothed  from  the  inferior  part  of  the  segment. 

The  suture  between  the  first  two  segments  is  usually  entirely  ob- 
literated, but  in  Walsinghami  \s  visilile  at  the  sides;  in  some  speci- 
mens of  acutipennis,  and  more  rarely  bilineatus,  the  suture  is  faintly 
indicated.  The  pre.sence  of  this  suture  has  affi)rded  Mr.  Waterhouse 
the  means  of  separating  a small  number  from  the  mass  of  species  in 
Mexico. 

Legs. — The  legs  in  all  the  species  are  slender,  and  afford  very  few 
characters  useful  in  separation.  In  a good  number  sexual  differences 
have  been  observed  in  the  tibiae,  consisting  of  a short  spine  or  mncro 
at  the  inner  apical  angle  of  the  anterior  tibia  and  sometimes  {otiosus, 
etc.,  FI.  viii,  fig.  18)  on  all  the  tibiae  of  the  male;  the  female  tibiae 
are  simple  in  all  the  species.  The  tarsi  vary,  apparently,  in  length. 
Apparently,  because  in  estimating  their  length  some  comparison 
must  be  made  with  adjacent  parts,  and  it  will  be  found  in  nearly 
every  case  the  tarsi  bear  the  same  relation  in  length  to  the  tibia. 

The  claws  vary  greatly  in  form,  affording  nsefnl  characters  in 
grouping  the  species,  although  the  demarcation  is  not  so  sharply 
defined  as  to  render  differences  primarily  useful. 

In  no  case  are  the  claws  simple,  or  even  approaching  that  condition. 
Mr.  Crotch  remarked  that  while  the  claws  of  many  European  species

were  bifid,  they  were  not  so  in  any  American  form  that  he  had  seen. 
It  seems  to  me  that  a careful  homological  study  of  the  claws  shows 
that  in  all  our  species  these  members  are  either  bifid,  or  of  a modified 
l)ifid  form.  While  they  are  usually  called  cleft,  there  is  no  truly 
cleft  claw  in  any  species.  If  we  examine  the  species  related  to  }W- 
litus  and  those  near  torpidus,  the  claws  will  he  found  so  nearly  of  the 
true  bifid  type  that  they  should  he  called  so.  Tracing  the  modifica- 
tions of  this  form  it  will  be  observed  that  the  inner  member  of  the 
bifid  tip  gradually  shortens  and  broadens,  while  it  preserves  its  lateral 
position  in  relation  to  the  other  part,  although  becoming  quite  a 
broad  tooth. 

It  seems  not  to  have  been  noticed  that  in  the  group  above  indicated 
the  claws  are  not  only  different  in  the  two  sexes,  but,  especially,  in 
the  male,  different  on  the  three  pairs  of  feet.  This  effectually  pre- 
vents anything  but  the  most  I’estricted  use  of  the  forms  of  the  claws 
in  separating  either  groups  of  species  or  species  themselves. 

As  the  descriptions  of  the  modifications  of  the  claw  would  be  an 
unnecessary  rei)etition  at  this  time,  the  student  is  referred  to  the 
remarks  under  each  species. 

At  this  time  I desire  to  acknowledge  the  assistance  received,  with- 
out which  this  essay  would  have  fallen  short  of  its  present  complete- 
ness. The  Museum  of  Comparative  Zoology  has  permitted  the  free 
use  of  the  LeConte  collection  for  conq)arison,  without  which  the 
names  here  used  would  have  less  certain  value.  The  National  Mu- 
seum, through  its  Curator,  Dr.  C.  V.  Riley,  has  loaned  its  material, 
which  has  in  one  case  removed  a doubt  from  my  mind,  and  in  several 
others  prevented  the  necessity  of  describing  from  uniques.  The 
cabinet  of  the  American  Entomological  Society  has  ako  been  freely 
used.  To  Messrs.  Ulke,  Liebeck,  Seeber,  Wenzel  and  Henshaw,  I 
am  indebted  for  the  free  use  of  their  material  and  the  gift  of  speci- 
mens. Finally,  to  Mr.  Fred.  Blanchard,  of  Low’ell,  I am  under 
especial  obligations  for  his  many  useful  suggestions,  and  for  his  hav- 
ing very  kindly  studied  several  difficult  questions  regai’ding  the 
of imus  senes  on  the  carefully  collected  material  in  his  cabinet. 

The  meaning  of  the  expressions  used  in  the  subsequent  j>ages  of 
the  essay  having  been  sufficiently  explained,  the  following  table  is 
presented  to  enable  the  species  to  be,  at  least  approximately,  deter- 
mined. The  arrangement  of  the  species  by  the  sequence  in  the  table 
does  not  in  all  cases  ajjproximate  those  having  a superficial  resem- 
blance. The  object  of  this  study  is  to  enable  the  determination  of

adopted,  and  in  general  use  everywhere,  it  has  been  retained  for  the  species. 
As  Say  described  both,  and  as  one  or  the  other  must  be  a synonym,  it  seems 
to  matter  but  little  which  one  is  suppressed. 

.4.  (liflioilis  Gory.  — Form  elongate,  piceous,  with  a faint  greenish  or  cupre- 
ous surface  lustre.  Antennae  piceous,  slightly  bronzed,  reaching  beyond  the

GEO.  H.  HORN,  M.  D. 


Male. — Front  flatter,  more  densely,  but  more  finely  pnncfate, 
nsually  greenish  in  color;  prosternnm  densely  punctate  along  the 
middle  with  (piite  fine,  sub-erect,  silken  pul)escence ; metasternum 
convex  ; ventral  segments  similar  in  the  sexes,  not  impressed. 

Female. — Front  more  coarsely  punctate,  color  more  or  less  cupre- 
ous; prosternum  rather  coarsely,  not  closely  punctate,  not  pubescent. 

Variations. — The  only  variations  noted  are  those  of  size  and  color, 
which  do  not  change  the  aspect  of  the  species  in  any  great  degree. 

Of  the  habits  of  this  species  nothing  has  been  recorded.  This  is 
one  of  the  larger  species  in  our  fauna,  although  several  exceed  it  in 
size. 

The  claws  are  cleft,  and  with  the  lower  portion  incurved,  as  re- 
(piired  in  the  group,  although  less  incurved  than  usual,  so  that  the 
])oints  are  (piite  distant.  This  divergence  from  the  tyjie  of  the  group 
is  the  more  marked  in  the  male,  the  claws  of  the  other  sex  being 
nearly  contiguous. 

Hab. — Occurs  in  the  Mississippi  Valley  from  IMissouri  to  Texas. 

A.  11.  sp. — Form  robust,  obscure  seneous,  opaque.  Autenuae  short, 

serrate  from  the  fourth  joint,  slightly  cupreous;  head  densely  coarsely  punctate, 
slightly  strigose  on  the  occiput,  lougitudiiially  impressed  from  the  occiput  to  the 
clypeus.  Thorax  broader  tlian  long,  slightly  narrowed  in  front,  sides  straight, 
arcuate  near  the  front,  lateral  line  not  sinuous,  base  slightly  broader  than  the 
humeri,  a moderately  deep  impression  behind  the  front  angles,  which  is  entirely 
lateral,  median  line  rather  broadly  and  deeply  concave,  hind  angles  not  carinate 
% , obsoletely  carinate  9 ; surface  coarsely,  closely  and  irregularly  strigose,  the 
intervals  between  the  ridges  punctate;  elytra  broadest  at  base,  scarcely  dilated 
behind  the  middle,  apices  separately  rounded,  .scarcely  serrulate,  basal  depres- 
sions almost  obliterated,  disc  rather  flat,  vaguely  concave  along  the  middle  of 
each  side  ; surface  densely  granulate,  strigose  ; body  beneath  similar  in  color,  but 
very  obtuse,  intercoxal  process  rather  broad,  parallel  and  very  obtuse  at  apex, 
propleiiraj  coarsely  punctate,  slightly  strigose;  abdomen  finely  punctate  at  mid- 
dle, more  densely  and  roughly  at  the  sides,  the  lateral  marginal  line  entirely 
obliterated  on  the  first  two  segments;  x)ygidium  jninctate,  indistinctly  carinate; 
claws  similar  on  all  the  feet.  Length  .36  inch. ; 9 mm. 

Male. — Prosternnm  densely  punctate  and  rugulose  sparsely,  finely 
pubescent.  Ventral  segments  not  impressed. 

Female.  — Unknown. 

The  two  specimens  before  me  show  no  variation. 

The  entire  obliteration  of  the  marginal  line  on  the  first  two  ventral 
segments  is  a character  not  observed  elsewhere  in  our  species. 

In  form  and  general  appearance  this  species  resembles  obolinns, 
which  is  also  remarkable  in  having  the  marginal  line  of  the  abdomen 
faintly  indicated  on  the  first  segment. 

llab. — Texas,  ])robably  near  the  lower  Rio  Grande.

ciput to  the  clypeus,  closely  coarsely  punctate,  slightly  pubescent;  across  the 
base  of  the  clypeus  a slight  cariua,  and  above  each  antennal  fossa  a rather  deep 
groove.  Thorax  nearly  twice  as  wide  as  long,  sides  irregularly  arcuate,  lateral 
marginal  line  sinuous,  disc  irregularly  convex  ; a broad,  vague,  lateral  depression,

Variations:. — So  few  specimens  have  been  collected  that  hut  little 
variation  has  been  observed.  The  thorax  is  entirely  cupreous,  the 
median  line  more  golden,  and  on  each  side  of  this  is  a longitudinal 
space  of  darker  color,  which  varies  in  its  intensity  of  color  and 
extent. 

Of  its  habits  nothing  is  known. 

Hab. — Tennessee  and  Georgia. 

.V.  riitirollis  Fab. — Black,  or  blue-black;  head  and  thorax  usually  bright 
cupreous.  Autennse  black,  serrate  from  the  fourth  joint,  the  serrate  joints  as 
wide  as  long;  occiput  rather  deei)ly  impressed,  the  line  extending  to  the  base

costfe ; body  beneath  piceous  black,  witli  faint  bronze  surface,  shininfi;  proster- 
nuni  obtusely  lobed  in  front  with  deep  transverse  impression,  the  process  gr.ad- 
ually  narrowed,  acute  at  apex  ; surface  coarsely  punctate,  more  rugose  posteriorly  ; 
metasternum  granulate;  abdomen  granulate  at  base,  the  sculpture  becoming 
rapidly  liner  toward  apex,  where  the  segment  is  finely  or  sparsely  punctate; 
pygidium  carinate,  the  carina  projecting  in  a spine;  the  vertical  portion  of  the 
ventral  segments  punctate  and  sparsely  pubescent;  claws  similar  on  all  the  feet 
in  both  sexes.  Length  .22 — .28  inch.;  5. .5— 7 mm. 

Male. — Front  more  deeply  impressed,  less  coarsely  jninctate  ; elytra 
not  wider  at  the  post-median  expansion  tlian  at  the  humeri ; proster- 
num more  coarsely  punctate,  metasternum  slightly  concave  ; first 
ventral  segment  concave  along  the  middle,  the  second  segment  rather 
deeply  grooved  for  three-fourths  its  length,  the  groove  smooth. 

Female. — Front  flatter,  more  closely  punctate,  less  deejily  grooved  ; 
elytra  wider  at  the  })osterior  dilatation  than  at  the  humeri  ; proster- 
nuin  more  spansely  punctate,  metasternum  convex  ; first  two  ventral 
segments  not  grooved,  the  surface  smoother  than  in  the  male. 

Variations. — The  normal  and  most  common  form  has  the  head  and 
thorax  of  bright  cupreous  color,  the  elytra  black,  .sometimes  with 
a slight  tinge  of  blue.  The  color  of  the  head  and  thorax  is,  at  times, 
quite  brassy  shading  gradually  to  green.  Specimens  more  rarely 
occur  with  these  j)arts  quite  black,  although  with  more  gloss  than 
the  elytra.  In  all  other  characters  excepting  size,  the  species  is  re- 
markably constant. 

Habits. — The  larva  of  this  insect  feeds  in  the  stems  of  Blackberry 
and  Raspberry,  emerging  in  the  early  Summer.  An  excellent  article 
illustrating  the  injuries  done,  together  with  a figure  of  the  larva,  will 
be  found  in  “ Insects  Injurious  to  Fruits,”  by  Wm.  Saunders  (J.  B. 
Lippincott  Company). 

Hab. — Occurs  from  Canada  and  the  New  England  States  south- 
ward to  Virginia  and  westward  to  Missouri. 

A.  lateralis  Say. — Form  of  ruficollis.  Head  and  thorax  cuiireous;  elytra 
black,  with  slight  feneous  lustre.  Anteniire  piceous,  slightly  bronzed,  scarcely 
attaining  the  middle  of  the  thorax,  serrate  from  the  fourth  joint ; head  imjiressed 
from  the  occiput  to  the  clypeus,  less  deeply  than  in  ruficollis.  entire  head  rather 
coarsely  and  closely  punctate.  Thorax  broader  than  long,  not  narrowed  at  base,

erately deep  oblique  lateral  depression  ; surface  transversely  strigose,  siibgranu- 
late  at  middle  in  front;  scutellum  transversely  carinate,  less  distinctly  in  % ;

disc  moderately  convex,  without  trace  of  costa;  surface  densely  granulate,  but 
less  opaque  than  in  ruficolUs  ; body  beneath  piceous  with  teneous  lustre;  proster- 
nal  lobe  slightly  eniarginate,  the  intercoxal  process  gradually  narrowed,  the  tips 
acute;  pro-  and  nietapleurae  closely  punctate,  not  pubescent;  abdomen  moder- 
ately closely  punctate,  more  finely  along  the  middle,  niore  coarsely  and  roughly 
at  the  side  of  the  first  segment ; pygidium  coarsely  punctate,  carinate,  the  carina 
ju'ojecting  at  tip;  claws  similar  on  all  the  feet  in  both  sexes,  the  lower  portion 
of  the  cleft  more  nearly  contiguous  in  the  female.  Length  .25 — .28  inch.;  6.25 
— 7 mm. 

Male. — Pmsteriumi  coarsely,  not  closely  punctate,  without  jtubes- 
cence ; first  ventral  segment  slightly  depressed  along  the  middle, 
second  with  a deep,  smooth  groove  extending  more  than  half  its 
length. 

Feiaale. — Prosternum  less  punctate,  smoother  ; first  two  ventral 
segments  simple. 

Four  specimens  have  afforded  the  above  description.  Another 
specimen  in  Mr.  Ulke’s  collection  is  of  somewhat  larger  size,  and 
with  more  even  thorax,  seems  to  belong  here,  although  the  discovery 
of  the  male  may  prove  it  distinct. 

This  species  greatly  resembles  ruficolUs,  but  may  be  distinguished 
by  the  less  deeply  impressed  head  and  the  presence  of  either  a slight 
evidence,  or  a distinct  carina,  in  the  hind  angles  of  the  thorax.  The 
sexual  characters  of  the  two  are  practically  identical ; several  other 
species  have  also  some  resemblance,  but  these  have  no  pygidial  spine. 

HabiU — The  wood  in  which  the  larva  lives  is  not  known,  but  the 
imago  has  been  taken  on  foliage  of  Poplar  sprouts  (Blanch.  Ent. 
Am.  V,  p.  o2,  under  the  name  auxins). 

Hab. — Massachusetts  (Blanchard),  New  Jersey  (Liebeck),  New 
Mexico  (Ulke),  Illinois  (Dury),  Missouri  (Say). 

.4.  otioKiis  Say. — Form  slender,  sometimes  linear  in  the  male,  stouter  in  the 
female,  usually  dull  greenish,  sometimes  slightly  cupreous.  Antennae  usually 
bluish,  extending  nearly  to  the  hind  angles  of  the  thorax,  a little  shorter  in  the 
female,  joints  all  longer  than  wide,  serrate  from  the  fourth  joint;  head  viewed 
from  above  slightly  convex,  with  a very  slight  occipital  impression,  front  rather 
flat,  coarsely  and  closely  punctate,  occiput  faintly  strigose.  Thorax  a little  wider 
than  long,  slightly  narrowed  at  base  in  the  male,  sides  feebly  arcuate,  but  more 
distinctly  in  the  female,  lateral  edge  straight  , or  feebly  sinuous  hind  an- 
gles obtusely  or  indistinctly  carinate  , or  usually  with  a well  defined  carina  9 , 
disc  convex,  an  oblique  lateral  depression  and  on  the  median  line  two  depres- 
sions, the  posterior  the  larger;  surface  transversely  strigose,  with  fine  punctures 
between;  scutellum  transversely  carinate;  elytra  slightly  sinuate  behind  the 
middle,  entii-ely  concealing  the  abdomen  from  above,  apices  separately  rounded, 
finely  serrulate,  elytra  with  a vague  costa  from  the  humeri  behind  the  middle, 
between  which  the  elytra  are  slightly  flattened,  and  behind  the  middle  the  su-

tiiral  edge  is  slightly  elevated  ; basal  depressions  distinct;  surface  with  a densely 
imbricate  sculpture;  body  beneath  usually  bluish,  more  shining  than  above; 
prosternal  lobe  obtuse,  vaguely  emarginate,  the  intercoxal  process  gradually  nar- 
rowed and  acute  at  tip,  propleui'se  scabrous  or  subgranulate ; metasternum  coarsely 
punctate  ; abdomen  punctate,  more  sparsely  along  the  middle,  quite  coarsely  along 
the  side,  the  first  segment  quite  rough  ; pygidium  coarsely  punctate,  indistinctly 
carinate;  tarsi  slender,  the  first  joint  of  the  hind  tarsi  nearly  half  as  long  as 
thetibiic;  (daws  similar  on  all  the  feet  in  both  sexes.  Length  .16 — .22  inch.; 
4 — 5.5  mm. 

J/a/e. — Form  more  slender,  sometimes  tilmost  linear;  front  flatter, 
more  densely  punctured  ; hind  angles  of  thorax  less  distinctly  cari- 
nate ; prosternum  densely,  finely  punctate,  finely  pubescent,  the  pu- 
bescence usually  extending  along  the  median  line  of  the  body  to  the 
end  of  the  second  ventral  segment ; first  two  ventral  segments  vaguely 
sulcate  on  the  median  line.  Inner  apical  angle  of  all  the  tihiie 
spiniform  and  incurved. 

Female. — Form  stouter,  usually  with  more  evident  leneous  surface 
lustre ; front  slightly  more  convex,  more  coarsely,  but  less  closely 
punctate,  the  occipital  impression  extending  slightly  downward  ; hind 
angles  of  thorax  (piite  distinctly  carinate  ; prosternum  much  more 
sparsely  |)unctate,  not  hairy ; first  two  ventral  .segments  not  im- 
]>ressed  and  with  smoother  scul])ture. 

Variations. — The  most  striking  structural  variation  is  the  hind 
angles  of  the  thorax.  The  sexual  variation  has  already  been  re- 
corded, but  s])ecimens  are  before  me  as  completely  deprived  of  carina 
as  any  species  in  our  fauna,  not  only  males  but  females  also.  The 
smaller  and  less  developed  males  have  the  ventral  sexual  characters 
less  pronounced,  so  that  the  pubescence  along  the  median  line  be- 
comes less  distinct  and  the  sulcus  of  the  first  two  ventral  segments 
almost  entirely  disappears.  The  color  variations  are  not  great,  the 
males,  however,  are  in  a great  part  dull  bluish,  while  the  females  are 
slightly  greenish  or  cupreous. 

As  this  is  a common  and  well  known  species,  much  space  has  been 
given  to  its  description  as  a means  of  comparison  for  other  species. 
Say’s  A.  geminaius  is  undoubtedly  the  female  (T  this,  suhsecpiently 
described  by  him  as  otiosus.  The  former  name  has  priority  by  sev- 
eral years,  but  the  latter  name  is  retained  from  its  having  acquired 
general  acceptance,  and  from  the  fact  that  both  belong  to  the  same 
author  and  no  injustice  is  done.  This  is  clearly  one  of  those  cases 
in  which  the  law  of  priority  should  yield  to  that  of  convenience. 

Habits. — Feeding  on  Oak  shrubs  (Blanch.  Ent.  Am.  v,  p.  32).  I 
think  it  has  been  reared  from  Hickory  twigs  by  Dr.  LeConte.

Hab. — Canada  and  New  England  States ; westward  to  Kansas ; 
soutliward  to  Texas. 

A.  defectii!^  Lee. — Form  and  coloi-s  of  oiiosus.  Autennie  attaining  tlie  mid- 
dle of  the  thorax,  the  joints  scarcely  longer  than  wide,  serrate  from  the  fourth 
joint;  head  slightly  convex,  with  scarcely  a trace  of  occipital  impression,  front 
and  occiput  punctate.  Thorax  wider  than  long,  not)  narrower  at  base,  sides 
arcuate  from  apex  to  base,  hind  angles  obsoletely  carinate  in  both  sexes,  lateral 
margin  very  nearly  straight,  disc  convex,  a vague  oblique  depression  at  the  sides, 
two  dei)ressions  on  the  median  line,  but  feebler  than  in  otiosus  : surface  trans- 
versely strigose,  the  grooves  punctate,  more  distinctly  than  in  otiosus  ; scutellum 
transversely  carinate ; elytra  sinuate  behind  the  humeri  with  the  post-median 
dilatation  concealing  the  abdomen,  apices  rounded,  finely  serrulate,  disc  with 
scarcely  a trace  of  costa,  the  sutural  border  elevated  behind  the  middle,  basal 
depressions  feeble ; surface  imbricately  sculptured,  but  smoother  near  apex  ; body 
beneath  more  shining,  dull  bluish  green  ; prosternal  lobe  obtuse,  vaguely  emar- 
ginate,  the  intercoxal  process  gradually  narrowed  and  acute  at  tip,  propleura? 
moderately  closely  punctate;  metasternum  not  closely  imbricate.  Abdomen 
sparsely  punctate  along  the  middle,  a little  more  closely  at  the  sides;  pygidiuin 
coarsely  sparsely  punctate,  feebly  carinate;  tarsi  slender,  as  in  otiosus;  claws 
similar  on  all  the  feet.  Length  .16— .18  inch.;  4 — 4.5  mm. 

Male. — Front  more  opaque  and  finely  punctate;  prosternuni 
coarsely,  not  clo.sely  punctate,  rather  opaque.  First  two  ventral 
segments  faintly  grooved,  but  not  pubescent  ; last  ventral  truncate, 
with  a marginal  fringe  of  hairs,  curved  and  directed  downward. 
Inner  apical  angle  of  all  the  tibiae  s])iniform,  slightly  incurved. 

Female. — Front  more  shining  and  more  evidently  punctate  ; pros- 
ternum more  shining.  First  two  ventrals  not  grooved,  last  ventral 
oval  at  tip,  not  fimbriate. 

Of  the  habits  of  this  species  I have  no  information.  The  only 
variations  observed  are  those  of  color  as  in  otiosus,  the  females  rather 
more  brassy. 

There  can  be  very  little  doubt  that  this  species  was  originally  in- 
stituted to  contain  all  the  small  specimens  of  otio.ms  in  which  the 
Carina  of  the  hind  angles  of  the  thorax  is  nearly  or  (piite  Avanting. 
An  examination  of  the  series  showed,  however,  that,  abstracting  the 
true  otiosus,  there  remained  specimens,  one  of  which  bore  the  type 
label,  which  clearly  indicated  a distinct  species.  They  were,  how- 
ever, females.  A few  days  later  Mr.  Blanchard  gave  me  a male, 
which  was  clearly  a mate  for  the  type.  As  might  be  inferred  from 
the  preceding  i-emarks,  the  sjiecies  very  closely  resembles  small  or 
starved  specimens  of  otiosus.  There  need  be  no  ditficulty,  whatever, 
in  separating  the  males  from  any  Agrilus  in  our  fauna,  but  the  fe- 
males are  more  difficult.  It  will  be  observed,  however,  that  in  the 


294 


GEO.  H.  HORN,  M.  D. 


present  species  the  median  line  of  the  abdomen  is  very  smooth,  almost 
without  punctures.  In  fact,  the  entire  abdomen  is  less  sculptured 
than  usual.  When  once  a male  is  obtained  there  will  be  no  great 
difficulty  in  separating  the  female  from  otiosiis. 

It  is  evident  that  LeConte  had  before  him  a male  of  this  species 
which  he  mistook  for  the  male  of  laeu.st7'i.s,  but  I failed  to  find  the 
specimen  at  present  associated  with  that  species,  and  discovered  that 
it  had  been  removed  and  placed  with  the  present  species  either  by 
himself,  or  later  by  Crotch.

A.  criiiicoriiis  n.  sp.--Forra  slender,  as  in  otiosus,  color  olive-bronze  with 
a slight  bluish  tinge  at  the  sides,  slightly  shining.  Antennse  slender,  bluish, 
passing  the  hind  angles  of  the  thorax,  joints  all  longer  than  wide,  serrate  from 
the  fourth  joint,  fimbriate  on  the  posterior  side  with  comparatively  long,  sparsely 
placed  hairs;  front  rather  fiat,  a slight  occipital  depression,  subopaque,  sparsely 
punctate,  occiput  faintly  strigose.  Thorax  wider  than  long,  slightly  narrowed 
at  base,  sides  arcuate,  margin  slightly  sinuous,  hind  angles  not  at  all  or  very 
feebly  carinate,  disc  moderately  convex,  a deep  oblique  lateral  and  two  me<lian 
depressions  as  in  otiosus;  surface  indistinctly  transver.sely  strigose  on  the  disc 
with  intervening  punctures,  at  .sides  in  front  punctate;  scutellum  transversely 
carinate  ; elytra  sinuate  behind  the  hunjeri,  slightly  broadened  behind  the  mid- 
dle, apices  very  obtuse,  serrulate,  disc  with  a vague  costa,  the  intervening  space 
slightly  flattened,  sutural  edge  elevated  behind  the  middle,  basal  depressions 
moderate,  surface  closely  imbricately  sculptured,  rougher  near  the  base;  body 
beneath  more  shining  than  above,  blue;  prosternal  lobe  obtuse,  vaguely  emar- 
giuate,  the  intercoxal  pro<'ess  gradually  narrowed,  acute  at  tip,  propleurfe  opaque, 
.scabrous;  metasternum  more  roughly  scabrous.  Abdomen  sparsely,  finely  punc- 
tate at  middle,  more  coarsely  at  the  sides ; pygidium  coarsely  punctate,  not  at  all 
carinate;  tarsi  slender,  claws  similar  0!i  all  the  feet.  Length  .17  inch. ; 4.25  mm. 

Male. — Front  snbopaque,  alutaceous,  sparsely  ]mnctate  ; pro.ster- 
num  rather  flat,  opaque,  sparsely  punctate,  not  pubescent  ; first  two 
ventral  segments  rather  flat,  not  grooved  nor  pubescent ; inner  apical 
angle  of  the  tibite  spiniform  and  slightly  incurved. 

While  closely  related  to  otiosus,  the  male  gives  evidence  that  the 
species  is  quite  distinct.  Females  have  not,  with  certainty,  been 
separated,  consequently  it  is  not  po.ssible  to  assert  that  the  pilosity 
of  the  anteniue  is  peculiar  to  the  male.*  The  anteniue  are  certainly 
longer  and  more  slender  than  any  species  in  the  vicinity  of  otiosus. 

Hub. — Massachusetts  (Blanchard),  Pennsylvania  (Liebeck),  Illi- 
nois (Strumberg),  Virginia  (Ulke). 


■■■  Since  the  above  was  written  females  have  been  obtained  having  the  antennae 
similarly  pilose.

A.  iiiasciiliiiU!^  11.  sp. — Form  rather  slender,  but  more  robust  than  otiosvs, 
color  dull  green  or  slightly  brassy,  feebly  shining.  Antennre  greenish,  serrate 
from  the  fourth  joint,  these  longer  than  wide,  tip  reaching  the  hind  angles  of 
the  thorax;  head  slightly  convex,  a very  feeble  occipital  impression,  more  dis- 
tinct in  the  female,  front  densely  punctate,  occiput  slightly  strigose.  Thorax 
wider  than  long,  slightty  narrowed  at  base,  sides  in  front  arcuate,  a slight  sinua- 
tion  posteriorly,  lateral  margin  sinuate,  hind  angles  with  a sharply  defined  carina 
in  both  sexes,  disc  convex ; an  oblique,  but  not  deep  impression  at  the  sides,  two 
depressions  on  the  median  line  as  in  otiosus,  but  much  less  distinct;  surface  not 
coarsely  transversely  strigose,  with  fine  punctures  on  the  intervals;  scutellum 
transversely  carinate  ; elytra  slightly  sinuate  behind  the  humeri,  then  somewhat 
dilated,  concealing  the  abdomen,  apices  rather  obtusely  rounded,  finely  serrulate, 
disc  with  a vague  costa  on  each  side,  the  intervening  space  rather  flat,  sutural 
margin  elevated  behind  the  middle,  basal  depressions  shallow,  surface  closely 
imbricately  sculptured;  body  beneath  more  .shining  than  above  ; prosternal  lobe 
obtuse,  broadly  and  rather  deeply  emarginate,  the  intercoxal  process  gradually 
narrowed,  acute  »t  tip,  propleurse  closely  punctate  ; metasternum  at  sides  densely 
submuricately  sculptured.  Abdomen  closely  punctate,  and  on  the  first  two  seg- 
ments denser  and  submuricate ; pygidium  sparsely  punctate,  indistinctly  carinate ; 
hind  tarsi  slender,  as  long  as  the  tibiae,  the  first  joint  as  long  as  the  four  fol- 
lowing ; claws  similar  on  all  the  feet  in  both  sexes.  Length  .24  inch. ; 6 mm. 

Male. — Front  flatter,  more  opaque  and  more  densely  punctured, 
usually  greenish  ; prosternum  with  a space  in  front  densely  covered 
with  short  erect  pubescence,  the  intercoxal  jirocess  smoother,  with  a 
median  longitudinal  elevation.  First  two  ventral  segments  flattened, 
or  vaguely  concave  along  the  median  line,  not  pubescent.  Inner 
apical  angle  of  the  front  and  middle  tibiae  spiniform  and  incurved, 
posterior  tibiae  simple. 

Female. — Front  more  convex,  more  coarsely  and  less  densely  jiunc- 
tate,  usually  brassy  ; prosternum  not  hairy,  the  intercoxal  process 
flat.  Abdomen  not  impressed,  and  less  roughly  sculptured. 

Of  the  habits  of  this  species  I have  no  information.  The  four 
specimens  examined  show  no  variation  beyond  that  given  in  the 
detailed  description. 

It  is  highly  probable  that  this  species  is  mixed  with  otiosus  in  those 
collections  possessing  it.  In  fact,  so  great  is  the  superficial  resem- 
blance that  with  ordinary  compaiTson  they  could  not  be  separated. 
The  males  are,  however,  easily  separated  by  the  pubescent  area  at 
the  front  of  the  prosternum.  The  median  subcariniform  elevation 
of  the  intercoxal  process  bifurcates  about  the  middle  of  the  sternum 
like  a broad  letter  Y,  and  in  the  bifurcation  behind  the  emargina- 
tion  of  the  lobe  the  jnibescent  area  is  placed.  The  females,  if  I have 
correctly  separated  them,  are  not  so  easily  distinguished  from  the 
larger  females  of  otiosus,  Imt  I observe  that  in  both  sexes  the  elytra

are  much  more  obtuse  at  apex  than  in  that  species,  and  the  sutural 
angle  rather  better  defined. 

llab. — Canada,  New  York  and  Illinois.  The  two  supposed  females 
are  from  Mt.  Tom  and  Tyngshoro,  Mass.,  and  were  collected  by  Mr. 
Blanchard,  wlio  separated  them  as  not  being  fully  in  accord  with 
normal  females  of  otiosvs. 

\.  aroiiufiis  Say. — Moderately  elongate,  not  more  robust  than  ruficoUis  ; 
head  and  thorax  brassy,  cupreous,  or  slightly  greenish  ; elytra  varying  from 
dark  olivaceous  to  bright  brassy  or  cupreous.  AnteniiiB  ])iceous,  slightly  bronzed, 
passing  the  middle  of  the  thorax,  seri-ate  from  the  fourth  joint ; front  moderately 
impressed  from  the  occiput  nearly  to  the  base  of  the  clypeus;  surface  coarsely, 
moderately  closely  i)unctate,  somewhat  strigose  on  the  occiput.  Thorax  one- 
fourth  wider  than  long,  not  narrowed  at  base:  sides  regularly  arcuate,  the  mar- 
gin slightly  sinuous,  disc  convex,  the  median  line  with  an  anterior  and  posterior 
depression,  an  oblique  depression  at  the  side  nearly  reaching  the  median  line; 
surface  transversely  sti  igose,  with  punctures  in  the  depre.ssions  and  more  numer- 
ous near  the  apex,  hind  angles  with  an  arcuate  carina,  rather  sharp  or  obtuse 
'J,  ; elytra  slightly  sinuate  behind  the  humeri  and  dilated  behind  the  middle, 
nearly  concealing  the  abdomen,  apices  separately  rounded,  finely  serrulate,  disc 
slightly  flattened  at  middle,  basal  depressions  moderately  deep,  sutural  ridge 
elevated  behind  the  middle;  surface  rather  densely  imbricate,  but  not  opaque; 
body  beneath  usually  cupreous ; prosternal  lobe  broadly  emarginate,  the  inter- 
coxal  jtrocess  gradually  narrowed,  acute  at  tij),  proplenrpe  scabrous,  slightly  stri- 
gose; metaste.ru um  coarsely  pnnctate-strigose.  Abdomen  moderately  finely 
punctate,  imu-e  coarsely  at  tbe  sides  of  the  first  two  segments;  pygidium  coarsely 
punctate,  not  carinate.  Length  .20 — .36  inch. ; 5 — 9 mm. 

Male. — Front  flatter  and  more  nsnally  greenisli,  the  impression 
less  defined;  prosternum  closely  itunctate  and  slightly  pubescent; 
metasternum  longitudinally  impressed  ; first  ventral  segment  slightly 
flattened,  not  hairy  ; anterior  and  middle  tibite  with  a slight  mucro 
at  the  inner  apex,  the  posterior  simple. 

Female. — Head  more  convex,  the  frontal  impression  dee|)er  and 
sometimes  bifurcate  near  the  clypeus,  color  copj^ery  or  brassy  ; pro- 
sternum more  shining,  less  closely  punctate,  not  hairy  ; metasternum 
feebly  impre.ssed  ; abdomen  simple  ; tibio3  not  mucronate. 

Variations. — 'fhe  variations  of  this  species  are  so  pronounced  that, 
with  a limited  series,  three  species  might  be  indicated,  as  has  in  fact 
been  done.  The.se  are  as  follows : 

Var.  torquatus  Lee. — Head  and  thorax  brassy,  or  slightly  coppery 
or  greenish,  elytra  dark  olivaceous. 

This  form  is  widely  distributed  : Massachusetts,  ^Michigan,  Mon- 
tana, Illinois,  Kansas,  Kentucky,  Pennsylvania.  Thei'e  is  often  a 
great  resemldance  between  some  of  the  smaller  females  of  this  and

the  larger  females  of  oUo.'ius,  and  at  present  I am  unable  to  give  any 
positive  means  of  separating  them,  except  the  experience  gained  in 
handling  large  numbers  of  specimens. 

Yar.  f if  If/ ens  Lee. — A little  more  shining  than  normal. 

Var.  coryli  Horn. — Color  uniformly  bright  brassy. 

This  form  occurs  in  Massachusetts,  Illinois,  Missouri,  Florida. 

Var.  obliquus  Lee. — Color  uniformly  coppery. 

The  type  of  this  form,  as  remarked  by  Crotch,  is  founded  on  a large 
female  ; in  fact,  all  the  specimens  I have  seen  are  of  that  sex.  These 
resemble  some  of  the  forms  of  poliius,  but  the  structure  of  the  claws 
will  separate  them. 

Habitft. — The  only  information  possessed  of  the  habits  of  this  spe- 
cies concerns  the  var.  coryli,  which  lives  on  the  Hazel  (Corylus)  ac- 
cording to  Mr.  Blanchard  (Ent.  Am.  v,  p.  32). 

Hub. — Massachusetts  to  South  Carolina,  westward  to  Kansas  and 
Montana. 

A.  ciiprieolliN  Gory.— Form  o?  riificollis  ; I)lack,  siihopaque ; head  and  tho- 
rax brassy  or  cupreous,  as  in  ruficoUis.  Antenufe  black,  slightly  bronzed,  .scarcely 
reaching  the  middle  of  the  thorax,  serrate  from  the  fourth  joint,  joints  4-10  as 
wide  as  long ; occiput  very  deeply  impressed,  front  not  impressed,  surface  coarsely 
punctate,  sparsely  on  the  front,  more  closely  on  the  vertex.  Thorax  broader 
tban  long,  not  narrowed  posteriorly,  sides  feebly  arcuate,  the  marginal  line 
strongly  sinuous,  liind  angles  with  an  obtuse  elevation  ; disc  convex,  with  a me- 
dian. rather  sharp  impression  posteriorly,  broadly  transversely  impre.ssed  in  front, 
at  sides  a deep  oblique  impression  almost  reaching  the  dorsum,  surface  coarsely 
transversely  strigose.  without  punctures;  scutellum  transversely  carinate  ; elytra 
very  feebly  sinuate  behind  the  humeri  and  with  a feeble  posterior  broadening, 
the  abdomen  concealed,  apices  separately  rounded,  serrulate,  disc  slightly  flat- 
tened with  very  feeble  trace  of  costa,  the  sutin-al  edge  slightly  elevated  behind 
the  middle,  basal  depressions  not  deep;  surface  closely  finely  granulate;  body 
beneath  black,  slightly  violaceous;  prosternal  lobe  bi'oadly  emarginate,  intercoxal 
process  gradually  narrowed,  acute  at  tip;  propleurte  finely  scabrous,  ojiaque; 
metasternum  at  sides  roughly  scabrous,  somewhat  strigose.  Abdomen  tran-s- 
versely  strigose  with  line  punctures  along  the  edge  of  the  strigte,  smoother  along 
the  middle  and  at  apex  than  at  the  sides;  pygidium  coarsely  punctate,  not  cari- 
nate; claws  similar  on  all  feet.  Length  .20  inch.  ; 5 mm. 

Male. — Prostenmm  opaque,  sparsely  punctate,  with  short  pubes- 
cence, ventral  segments  not  impressed  nor  flattened.  IMetasternum 
longitudinally  impresed.  Anterior  tibite  with  an  extremely  feeble 
incurved  mucro  at  tip,  middle  and  hind  tibite  siinjile. 

Female. — LI  n k n o w n . 

So  closely  does  this  species  resemble  raficollis,  that  at  first  glance 
it  might  readily  be  supposed  to  belong  to  that  species.  They  are

easily  separable  by  the  fact  that  tbe  former  lias  a well  marked  j)ro- 
jecting  Carina,  while  this  has  not.  The  occipital  impression  gives 
the  appearance  from  above  of  a bilobed  head,  and  the  impression 
does  not  extend  downward  on  the  front,  while  in  rnficollis  the  occiput 
is  rather  concave  and  the  impression  reaches  the  clypeus. 

Occurs  in  Florida  at  St.  Augustine. 

•\.  aiij^elicus  ii.  sp. — Form  rather  robust,  as  in  muticus ; color  brassy,  mod- 
erately shining.  AuteuiiEe  piceoiis,  bronzed,  not  reaching  the  middle  of  the 
thora.x,  serrate  from  the  fourth  joint.  Head  slightly  convex,  a finely  impressed 
line  from  the  occiput  to  the  clypeus,  surface  finely,  not  closely  strigose,  sparsely 
punctate,  clypeus  much  broader  at  base  than  long  at  middle.  Tliorax  broader 
long,  base  and  apex  equal,  sides  arcuate  in  front,  sinuate  behind  the  middle, 
hind  angles  rectangular  with  a short,  acute,  straight  carina,  disc  convex,  a vague 
median  depression,  another  broad  depression  at  the  sides;  surface  transversely, 
not  coarsely  strigose  with  intermediate  sparse  punctures;  scutellum  not  trans- 
versely carinate  ; elytra  distinctly  sinuate  behind  the  humeri  and  broader  bebind 
the  middle,  the  apices  separately  rounded  and  very  feebly  serrulate ; disc  convex, 
without  trace  of  costae,  the  basal  depressions  moderate,  surface  rather  finely  im- 
bricately  sculptured ; body  beneath  more  shining  than  above;  prosternal  lobe 
obtuse,  broadly  but  feebly  emarginate,  the  intercoxal  process  gradually  narrow- 
ing, the  apex  acute,  propleurae  with  reticulate  sculpture;  metasternum  coarsely 
punctate,  reticulate.  Abdomen  finely  punctate-strigose  at  middle,  a little  more 
coarsely  at  the  sides,  the  first  segment  but  little  more  rugose;  pygidium  coarsely 
punctate,  feebly  carinate  ; claws  similar  on  all  the  feet.  Length  .25inch.:  6.5  mm. 

The  only  specimens  seen  are  females,  and  sliow  no  secondary  sexual 
characters.  The  lower  appendage  of  the  claws  is  less  incurved  than 
usual,  reaching  the  form  seen  in  difficilis.  Should  the  form  of  claws 
induce  one  to  place  it  elsewhere,  it  would  be  placed  in  the  series  near 
muticus,  from  any  of  which  it  will  be  known  by  the  acute  prosternum. 

One  specimen  collected  by  Mr.  D.  W.  Coquillett  near  Los  Angeles  ; 
Sta.  Cruz  ^Mountains,  Cal.  (Nat.  Mus.) 

A.  iiiacer  Lee. — Elongate,  cupreo-aeneous,  feebly  shining.  Antennae  piceous, 
with  brassy  lustre,  nearly  reaching  the  middle  of  the  thorax,  serrate  from  the 
fourth  joint;  front  flat,  or  slightly  concave;  occiput  feebly  impressed,  the  line 
extending  to  the  middle  of  the  front,  surface  rather  uneven,  densely  coarsely 
punctate,  slightly  strigose  on  the  occiput,  a well  marked  transverse  ridge  at  the 
base  of  the  clypeus.  Thorax  nearly  a third  wider  than  long,  very  slightly  nar- 
rowed at  base,  sides  feebly  arcuate,  margin  slightly  sinuate,  hind  angles  rectan- 
gular, the  carina  well  marked  and  directed  internally,  disc  convex,  a vague  me- 
dian depression  near  the  base,  lateral  depression  broad,  but  not  deep ; surface  not 
deeply  transversely  strigose,  punctate  between  the  strig*,  near  the  sides  and 
front  angles  more  densely  strigoso-punctate ; elytra  narrowed  from  the  base  with 
a very  feeble  post-median  broadening,  the  ajiices  rounded,  rather  strongly  ser- 
rate, disc  with  a well  marked  costa  extending  from  the  humeri  nearly  to  apex, 
the  interval  quite  flat,  the  sutural  border  elevated  slightly  from  apex,  two-

thirds  to  base,  basal  depressions  shallow,  surface  punctate-granulate,  rather 
densely  between  the  costie,  more  sparsely  at  the  sides;  body  beneath  similar  in 
color;  prosternal  lobe  broadly  emarginate,  the  interc.oxal  process  broad  with 
parallel  sides,  very  abruptly  narrowed  at  the  apex,  where  it  enters  the  meta- 
sternum;  propleurie  closely  punctate,  finely  fulvo-pubescent ; metasternum  at 
sides  very  densely  punctured  and  subopaque,  finely  pubescent.  Abdomen 
densely  punctured  at  the  sides,  especially  in  front,  rather  sparsely  along  the 
median  line ; last  segment  very  obtuse,  subtruncate,  the  vertical  portion  of  the 
segments  rather  densely  fulvo-pubescent;  pygidium  carinate,  the  carina  pro- 
jecting and  emarginate  at  tip ; claws  divaricate,  broadly  toothed  at  base.  Length 
.35 — .58  inch. ; 9 —15  mm. 

Male. — Front  slightly  concave  ; scutelluni  scarcely  visibly  carinate. 
Prosternntn  densely  punctate  and  slightly  pubescent  along  the  mid- 
dle. Ventral  segments  simple;  anterior  tibite  feebly  mucronate. 

Female. — Front  flat,  but  irregular;  scutellum  distinctly  carinate  ; 
prosternum  not  densely  punctate  nor  hairy  ; tibiae  simple. 

No  variation  worthy  of  note  has  been  observed  in  this  species. 

In  the  original  description  the  scutellum  is  said  to  be  not  carinate, 
but  this  proves  in  this  instance  to  be  merely  a sexual  peculiarity,  as 
it  is  quite  certain  that  Dr.  LeConte  had  a male  before  him. 

No  difficulty  need  be  experienced  in  recognizing  this  species,  as  it 
is  one  of  but  few  having  a well  defined  elytral  costa,  and  for  this 
reason,  especially,  seems  rather  out  of  place  among  our  species. 

Hah. — Texas,  at  Eagle  Pass,  and  other  localities  in  the  southwestern 
jiortion  of  the  State. 

-4.  vittatocollis  Eand. — Form  generally  resembling  a ]nr^e  rujicoHis ; head 
and  thorax  coppery,  subopaque,  elytra  black,  opaque.  Anteniipe  passing  the 
middle  of  the  thorax,  serrate  from  the  fourth  joint,  piceons,  faintly  bronzed  ; 
front  slightly  concave,  the  occiput  more  deeply  impressed,  the  median  impressed 
line  extending  to  the  base  of  the  clypeus,  surface  rather  closely  strigose  and 
punctate,  clothed  with  golden-yellow  pubescence,  except  near  the  upper  half  of 
the  eye.  Thorax  fully  one-third  wider  than  long,  sides  rather  strongly  arcuate, 
the  margin  sinuate,  disc  convex,  with  a median  shallow  imj)ression  extending 
from  base  nearly  to  apex,  lateral  depressions  vague,  hind  angles  not  cai-inate. 
surface  closely  strigose,  the  strigte.  oblique  in  front,  transverse  near  the  base,  a 
median  band  of  golden  pubescence  extending  from  the  basal  to  the  apical  margin, 
a l)roader  band  of  similar  pubescence  adjacent  to  the  lateral  margin,  the  hind 
angle,  however,  not  pubescent;  scutellum  transversely  carinate;  elytra  distinctly 
sinuate  behind  the  humeri,  broadened  behind  the  middle,  nearly  concealing  the 
abdomen,  apices  rounded,  serrulate ; d i.sc  slightly  flattened,  without  trace  of  costse  ; 
the  sutural  edge  slightly  elevated  at  apical  third,  basal  fovete  moderate;  surface 
densely  granulate  and  opaque;  body  beneath  black,  slightly  seneous,  with  very 
sparse,  fine  golden  pubescence ; prosternal  lobe  obtusely  truncate,  the  intercoxal 
process  broad,  very  little  narrowed,  except  at  apex,  where  the  narrowing  is  ab- 
rupt, at  which  point  the  sides  are  slightly  bent  downward  forming  a tooth  ; the 
surface,  with  the  propleurte,  closely  punctate;  metasternum  at  sides  densely

puiictiite  iuul  strigose.  Abdomen  finely  punctate,  sparsely  along  the  median  line, 
more  densely  at  the  sides,  especially  on  the  first  two  segments,  which  ai-e  also 
slightly  strigose,  the  vertical  portion  of  the  segments  densely  clothed  with  golden 
])iihescence ; last  segment  obtuse  at  tip;  pygidium  coarsely  punctate,  rather 
strongly  carinate,  the  carina  projecting  and  truncate  at  tip ; claws  dissimilar  in 
the  sexes.  Length  .31 — .37  inch.;  8 — 9.5  mm. 

Male. — Prostennmi  densely  jtunctured  and  opaque,  not  pnltescent. 
First  ventral  segment  slightly  flattened  at  tniddle  and  rugulose,  the 
second  with  a very  feeble  longitudinal  depression  ; tibiae  of  all  three 
pairs  distinctly  inucronate  at  the  inner  apical  angle ; claws  of  front 
feet  almost  truly  bifid,  middle  feet  less  so,  posterior  feet  nearly  toothed. 

Female. — Prosternum  less  densely  punctate  and  more  shining. 
Ventral  segments  not  impressed  ; tibiae  not  inucronate  at  tip  ; claws 
rather  broadly  toothed  on  all  three  jiairs  of  tarsi. 

Among  the  numerous  specimens  examined  no  variation  worthy  of 
mention  lias  been  observed.  Jiesemhles  fuscipennis,  but  the  color  of 
the  thorax  of  that  species  is  due  to  varying  color  of  the  surfoce,  and 
not  to  the  presence  of  pubescence,  as  in  the  present  species. 

Hab. — Massachusetts,  westward  to  Illinois.  A specimen  ( 9 ) in 
my  cabinet  from  Nevada  is  at  present  not  sejiarable,  but  the  male 
may  show  it  to  be  distinct  when  discovered. 

.4.  audax  n.  .sp. 

The  species  for  which  this  name  is  proposed  so  closely  resembles 
vittatocullis,  that  it  seems  unnecessary  to  repeat  the  description,  only 
the  points  of  diflerence  will  be  given. 

Thorax  similar  iu  color,  but  rather  more  evidently  transversely  strigose,  the 
median  line  of  golden  pubescence  does  not  reach  the  apical  margin,  the  lateral 
pubescent  area  is  separated  from  the  margin  by  a naked  edge,  hut  the  pubes- 
cence extends  to  the  hind  angles;  body  beneath  more  brassy,  the  propleurae, 
mesopleurie,  metapleurai  and  outer  half  of  coxal  plate  with  golden  pubescence. 
Length  .35— .40  inch. ; 9 — 10  mm. 

Male. — Prosternum  closely  punctate,  not  pubescent,  the  intercoxal 
process  gradually  narrowed  without  dentiform  reflexion  of  the  edge. 
First  ventral  segment  slightly  flattened  at  middle,  the  second  with  a 
rather  deep  smooth  groove,  which  is  wider  in  front,  extending  three- 
fourths  to  the  posterior  edge  of  the  segment;  anterior  and  middle 
tibirn  feebly  inucronate,  the  posterior  simple  ; claws  nearly  as  in 
vittatocollis. 

Female. — Prosternum  less  closely  and  deeply  punctate.  Ventral 
segments  simple ; tibiie  not  inucronate  ; claws  as  in  vittatocollis. 

This  species  presents  the  closest  resemblance  that  it  seems  possible

for  one  species  to  have  to  another.  The  males  are  abundantly  dis- 
tinct by  the  ventral  charactei’s,  but  both  sexes  can  be  separated  from 
vittatocollis  by  the  hairy  jdeuras  and  coxal  plates. 

Hab. — Texas. 

A.  biliiiesitii!^  Weber. — Black,  with  sometimes  a slightly  greenish  tinge, 
opaque;  sides  of  thorax  clothed  with  yellow  pubescence,  and  a vitta  of  same 
from  the  humeri  three-fourths  to  the  tip  of  the  elytra.  Antennae  slightly  aene- 
ous, extending  beyond  the  middle  of  the  thorax,  serrate  from  the  fourth  joint; 
front  slightly  convex,  densely  coarsely  punctured,  occiput  impressed,  the  line 
extending  to  the  middle  of  the  front.  Thorax  one-third  wider  than  long,  dis- 
tinctly narrower  at  base,  sides  nearly  straight  anteriorly,  sinuate  near  the  hind 
angles,  which  are  sharply  rectangular  and  not  carinate,  margin  sinuous;  disc 
convex,  a very  vague  median  depression,  the  lateral  oblique  impression  short; 
surface  rather  finely  transver-sely  strigoso-punctate,  the  sides  broadly  clothed 
with  golden,  rarely  whitish  pubescence  ; scutellum  transversely  carinate;  elytra 
sinuate  behind  the  humeri,  broadened  behind  the  middle,  apices  rounded,  serru- 
late ; di.sc  flattened,  the  basal  depressions  moderate,  sutural  edge  slightly  elevated 
at  apical  third,  surface  densely  granulate  and  subopaque,  with  a vitta  of  yellow 
or  whitish  hairs  extending  from  the  basal  depression  three-fourths  to  apex  ; body 
beneath  more  shining  than  above  and  more  greenish  ; prosternal  lobe  truncate, 
intercoxal  process  rather  broad,  gradually  narrowed  to  apex,  propleurse  granulate, 
sparsely  pubescent ; meso-  and  metapleur®  and  outerside  of  coxal  plates  rather 
densely  pubescent.  Abdomen  finely  and  sparsely  punctate  along  the  middle  and 
more  densely  and  coarsely  at  the  sides,  the  first  segment  rougher  and  strigose, 
the  vertical  portions  of  the  segments  densely  pubescent;  pygidium  coarsely 
punctate,  with  a strong  median  carina,  which  projects  at  apex  ; claws  dissimilar 
in  the  sexes.  Length  .22— .37  inch. ; 5.5 — 9.5  mm. 

Male. — Head  more  or  less  green,  more  densely  punctate  and  opaque. 
Prosternum  densely  punctate  and  subopaque,  esjtecially  between  the 
coxte,  not  pubescent.  First  ventral  segment  slightly  flattened  at 
middle,  the  second  with  a deep  smooth  groove  ; anterior  tibite  slightlv 
mucronate  at  apex,  the  others  sinq)le ; anterior  and  middle  claws 
almost  truly  bifid,  the  posterior  claws  with  a slender,  acute  tooth. 

Female. — Head  more  convex,  less  densely  punctured,  more  shining, 
with  lirassy  or  cuj)reous  lustre.  Prosternum  more  shining,  less  densely 
punctured.  Ventral  segments  simple;  tibiie  not  mucronate  ; claws 
with  a slender  acute  tooth  on  all  the  feet. 

Variations. — The  hair  forming  the  lateral  space  of  the  thorax  and 
the  vittie  on  the  elytra  is  usually  golden-yellow  in  color,  but  speci- 
mens often  occur  with  hair  quite  white  with  intermediate  shades. 
jNIore  rarely  specimens  occur  without  any  pubescent  markings  above, 
the  absence  of  hair  not  being  due  to  abrasion,  as  might  be  suspected, 
but  seems  to  be  the  result  of  starved  development,  as  all  the  speci- 
mens seen  are  of  the  smallest  size.

I[(ib. — Occurs  from  Maine  westward  to  the  Rocky  Mountains,  and 
south  to  Texas. 

.4.  gran  111  at  us  Say. — Form  rather  slender,  color  bra.ssy  bronze,  each  ely- 
tron with  three  indistinct  pubescent  spots — basal,  median  and  ante-apical,  the 
first  often  wanting.  Antennte  slender,  nearly  reaching  the  hind  angles  of  the 
thorax,  serrate  from  the  fourth  joint,  slightly  greenish  ; front  rather  flat,  occiput 
with  a linear  impression  extending  to  the  middle  of  the  front;  surface  coarsely 
closely  punctate,  occiput  slightly  strigose.  Thorax  wider  than  long,  scarcely 
narrowed  at  base,  sides  regularly  arcuate,  lateral  margin  faintly  sinuous,  disc 
convex  with  three  depressions,  the  one  larger  in  front  of  scutellum,  the  two 
others  in  front  on  each  side  of  middle  less  distinct,  or  even  absent,  the  lateral 
oblique  inqn-ession  well  marked,  hind  angles  with  a well  defined,  arcuate  carina; 
surface  transversely  strigose,  punctate  in  front;  scutellum  transversely  carinate  ; 
elytra  feebly  sinuate  behind  the  humeri,  slightly  broadened  behind  the  middle, 
apices  acute,  serrulate;  disc  slightly  flattened  at  middle,  the  sutural  margin 
elevated  behind  the  middle,  basal  foveas  moderate,  surface  rather  coarsely  im- 
bricate; body  beneath  darker  than  above  ; prosternal  lobe  emarginate,  the  inter- 
coxal  process  rather  broad,  parallel,  acute  at  tip,  the  propleurse  with  the  entire 
side  of  body  densely  clothed  with  yellowish  pubescence.  Abdomen  not  very 
closely  punctate,  the  sides  of  each  segment  with  a more  densely  punctured  spot 
clothed  with  pubescence,  the  vertical  portion  of  the  segments,  except  the  second, 
densely  imbesceut;  pygidium  coarsely  punctate,  with  a strong  median  carina, 
which  projects  at  tip;  claws  dissimilar  in  the  sexes.  Length  .30 — .35  inch.; 
7. .5 — 9 mm. 

Male. — Front  somewhat  greenisli.  Prostermim  quite  densely 
punctured  between  tlie  coxte,  more  sparsely  in  front;  first  ventral 
segment  longitudinally  impressed  with  a smooth  median  line,  second 
segment  more  deeply  impressed,  the  impression  smooth  and  extending 
nearly  to  the  suture;  anterior  and  middle  tihiie  feebly  nuicronate, 
the  posterior  simple  ; anterior  and  middle  claws  almost  bifid,  being 
cleft  at  the  tip,  posterior  claws  broadly  toothed.

tween the  coxie,  much  smoother  in  front  Ventral  segments  simple  ; 
tibim  sinqile;  claws  broadly,  but  acutely  toothed  on  all  the  feet. 

Variations. — In  all  well  preserved  specimens  there  will  be  obsei'ved 
a line  of  pubescence  extending  from  the  front  angles  of  the  thorax 
to  the  base,  passing  inside  of  the  carina.  The  pubescent  spots  of  the 
elytra  are  at  most  faint,  and  are  easily  removed  by  abrasion,  but  their 
position  is  always  indicated  by  a small  and  more  densely  punctured 
area.  The  three  discal  impressions  of  the  thorax  are  variable.  The

position  is  always  distinct,  but  the  two  in  front  may  escape  observa- 
tion. 

Of  the  habits  of  this  insect  nothing  is  certainly  known.  Care 
must  be  taken  not  to  confound  small  specimens  of  this  with  ohlongo- 
guttatm  (mterruptus)  or  fallax,  but  neither  of  the.se  has  the  pygidial 
spine. 

It  is  quite  clear  that  this  is  the  species  Say  had  before  him  from 
his  remarks  in  the  original  description,  and  a subsequent  note  (vide 
edit.  Lee.  ii,  pp.  104  and  596).  LeConte,  in  his  “ Revision,”  p.  245, 
admits  both  granulatus  and  quadriguttatus,  but  it  is  very  clear  that 
he  has  used  the  female  as  his  type  of  the  former  and  a male  for  the 
latter. 

Hub. — New  England  States  westward  to  IMissouri. 

iievadeiisis  n.  sp. — Form  elongate,  elytra  very  acute  at  ape.v,  piceous. 
subopaejue,  with  feeble  violaceous  lustre  beneath.  Antennse  nearly  attaining  the 
hind  angles  of  the  thorax,  with  bronze  lustre,  serrate  from  the  fourth  joint; 
front  feebly  convex,  a moderately  impresed  line  extending  from  the  occiput  to 
middle  of  front,  surface  closely  punctate,  a vague  fovea  each  side  of  middle. 
Thorax  uearly  a half  wider  than  long,  sides  arcuate  with  a slight  sinuation  near 
the  hiud  angles,  these  with  a strong  arcuate  carina,  disc  convex,  with  a broad, 
but  vague  median  impression  consisting  of  an  anterior  and  posterior  division, 
lateral  depression  shallow,  surface  comparatively  smooth  each  side  of  middle, 
some  vague  strigse  posteriorly  and  punctate  near  apex,  at  sides  densely  punctate; 
scutellum  not  transversely  carinate  ; elytra  scarcely  sinuate  behind  the  humeri, 
without  post-median  dilatation,  the  sides  of  the  abdomen  exposed,  apices  sepa- 
rately acute  and  somewhat  prolonged,  serrulate,  disc  slightly  flattened  at  middle, 
a vague  costa  on  each  side  and  three  depressions,  which  are  slightly  pubescent; 
basal,  median  and  one-third  from  apex,  surface  vaguely  not  closely  imbricate, 
less  closely  than  in  cavatus ; prosternum  closely  punctate,  the  lobe  distinctly 
emarginate,  intercoxal  process  gradually  narrowed,  acute  at  tip,  propleurse  closely 
punctate,  scabrous,  sparsely  pubescent;  metasternum  at  middle  comparatively 
smooth,  at  sides  closely  punctate  and  slightly  strigose.  Abdomen  nearly  smooth 
at  middle,  very  sparsely  punctate  at  sides,  even  on  the  first  two  segments,  very 
sparsely  pubescent,  the  vertical  portion  of  segments  sparsely  pubescent ; pygidium 
coarsely  punctate,  with  a median  carina,  which  projects  rather  strongly  at  apex. 
Length  .40  inch. ; 10  mm. 

Male. — U nkno  wn . 

Female. — Tiltite  not  mucronate,  claws  similar  on  all  the  feet,  cleft 
posteriorly  to  the  tip,  the  lower  portion  forming  an  acute  tooth. 

This  species  is  totally  unlike  any  other  in  our  fauna  from  the  acute 
and  somewhat  prolonged  elytra.  Its  general  form  is  not  very  unlike 
macer.  It  will  be  known,  however,  among  the  species  with  projecting 
carina  by  its  feeble  sculpture,  the  presence  of  the  three  pubescent

Hah. — Western  Nevada  (Morrison). 

A.  iii  v('i  vditri^  n.  sp. — Form  rather  more  slender  than  politus ; color 
bright  coppery,  with  the  thorax  slightly  brassy,  varying  to  olivaceo  cupreous. 
Antenna?  ieneous,  attaining  the  middle  of  the  thorax,  serrate  from  the  fourth 
joint.  Head  feebly  convex,  a slight  median  impressed  line  from  the  occiput  to 
the  middle  of  the  front,  the  latter  densely  punctate,  occiput  slightly  strigose. 
Thorax  one-third  wider  than  long,  sides  regularly  arcuate,  lateral  margin  slightly 
sinuate,  hind  angles  with  a strong,  arcuate  carina,  disc  convex,  with  a vague 
median  depression  composed  of  an  anterior  and  a posterior  depression,  lateral 
dej)ression  feel>le;  surface  transversely  strigose,  with  punctures  between  the 
strigse;  in  some  specimens  the  striga?  are  very  feehle;  scutellum  transversely 
carinate;  elytra  sinuate  behind  the  humeri,  slightly  broadened  behind  the  mid- 
dle, apices  separately  rounded,  finely  serrulate,  disc  slightly  flattened  at  middle 
with  an  extremely  vague  costa;  surface  with  imbricate  sculpture,  less  close  and 
more  shining  than  in  politus,  with  three  indistinct  pubescent  spots,  often  merely 
indicated  by  a slightly  denser  punctuation,  these  spots  placed  as  in  nevadensis ; 
prosternum  densely  punctured,  the  lobe  acutely  emarginate  at  middle,  the  inter- 
coxal  proce.ss  i)arallel,  acute  at  tip,  propleurse  densely  punctured  with  consiiicuous 
whitish  pubescence;  metasternum  at  sides  densely  |ninctate  and  transversely 
sti’igose,  pubescent  as  in  the  propleurpe.  Abdomen  sparsely  punctate  at  middle, 
more  densely  at  the  sides  and  finely  strigose,  especially  on  the  first  two  segments, 
vertical  portions  of  the  segments  densely  white  jiubescent;  pygidium  coarsely 
punctured  with  a strong  median  carina,  projecting  at  apex.  Length  .25 — .37 
inch.  ; 6.5 — 9.5  mm. 

Male. — Front  slightly  flatter;  tibise  not  distinctly  inncronate; 
claws  cleft  one-third  from  apex,  forming  an  achte  tooth  ; first  ventral 
segment  flattened  at  middle,  the  second  with  a slightly  depressed, 
smooth  space  at  anterior  half  of  middle. 

Female. — Front  slightly  convex  ; tibite  not  inncronate;  claws  cleft 
at  middle,  forming  an  acute  tooth.  Ventral  segments  convex  at 
middle,  the  first  much  smoother  than  on  the  male. 

VariatioiU. — The  color  variation  has  been  referred  to.  In  many 
specimens  there  is  on  each  side  of  the  median  line,  nearer  the  front, 
a fovea  which  is  as  often  absent.  In  very  carefully  collected  speci- 
mens the  sides  of  the  thorax  above  have  a white  efflorescence,  and 
the  body  beneath,  at  sides,  seems  very  densely  pubescent,  owing  to 
the  efflore.scence  between  the  hairs.  This  is,  however,  so  easily  lost, 
one  might  readily  suppose  two  specimens  to  be  distinct  species  which 
had  been  unecpially  handled  in  collecting. 

The  three  jnibescent  spots  on  the  elytra  are,  at  best,  very  feeble, 
and  some  care  must  be  used  in  their  observation. 

Habits. — Nothing  is  known  to  me.

Anteunse  rather  slenrter,  passing  the  middle  of  the  thorax,  slightly  greenish, 
serrate  from  the  fourth  joint.  Head  feebly  convex,  occi{)ut  slightly  impressed, 
the  line  extending  to  the  middle  of  the  front,  the  front  coarsely  and  closely

the  median  line,  sometimes  a fovea  on  each  side;  lateral  oblique  impressions 
distinct,  but  short;  surface  vaguely  transversely  sirigose  and  punctate;  elytra 
slightly  sinuate  behind  the  humeri,  and  a little  broadened  behind  the  middle 
apices  subacute  and  serrulate,  disc  slightly  flattened,  the  sutural  edge  elevated 
from  the  middle  to  the  apex  ; surface  imbricate,  more  closely  at  a])ical  third  and 
in  the  basal  foveae,  which  are  modei'ately  deep ; body  beneath  similar  in  color  to 
the  upper  surface,  but  more  shining;  prosternal  lobe  feebly  emarginate  at  mid- 
dle, the  intercoxal  process  moderately  broad,  acute  behind  the  coxae,  the  pro- 
pleurae grauulate-imbricate,  sparsely  pubescent;  metasternum  at  sides  roughly 
imbricate.  Abdomen  finely  punctate,  very  sparsely  at  middle,  more  closely  at 
the  sides,  the  first  segment  finely  strigose,  the  outer  surface  including  the  ver- 
tical portion  of  the  segments  finely  and  sparsely  pubescent;  last  ventral  segment 
very  obtuse  or  truncate  ; pygidium  coarsely  punctate,  with  a strong  carina,  w'hich 
projects  at  tip  ; claws  dissimilar.  Length  .30 — .32  inch.;  7.5 — 8 mm. 

Male. — Front  more  or  less  greenish.  Prosternuin  roughly  punc- 
tured, more  sparsely  in  front,  not  pubescent  ; first  ventral  segment 
flattened  at  middle,  the  second  with  a smooth  but  not  deep  gi-oove 
extending  two-thirds  the  length  of  the  segment;  anterior  tibite  feebly 
mucronate,  middle  and  posterior  tibiie  simple ; claws  of  front  tarsi 
cleft  close  to  apex,  almost  bifid,  middle  or  hind  claws  broadly  toothed. 

Female. — Front  cupreous,  and  somewhat  more  convex.  Proster- 
num but  little  smoother  than  the  male.  Ventral  segments  simple; 
tibise  not  mucronate;  claws  broadly  toothed  on  all  the  feet. 

The  six  specimens  before  me  show  no  variation.  In  its  general 
appearance  the  species  greatly  resembles  some  of  the  forms  of  politus. 

From  the  species  which  seem  most  closely  related  to  this  (anxms 
and  Blanchardi)  the  present  differs  primarily  in  color,  this  being 
cupreous,  they  olivaceous.  Color  characters  are,  however,  not  greatly 
to  be  regarded,  as  great  variations  do  occur.  On  the  male  sexual 
characters  it  is  better  to  place  more  reliance,  as  these  are  far  more 
constant.

arcuate,  margin  sinuous,  hind  angles  with  a strong  arcuate  carina  in  both  sexes, 
disc  convex,  with  a median  shallow  depression  formed  by  two  fovese,  on  each 
side  of  middle  usually  a smaller  fovea,  lateral  depression  moderately  deep,  but 
short;  surface  finely  transversely  strigose  with  fine  punctures  between;  scutel- 
lum  transversely  carinate ; elytra  slightly  sinuate  behind  the  humeri,  slightly 
broadened  behind  the  middle,  apices  subacutely  rounded,  serrulate,  disc  some- 
what flattened  with  a vague  costa,  the  sutural  margin  elevated  behind  the 
middle,  basal  depressions  moderately  deep;  surface  rather  densely  imbricate- 
granulate;  body  beneath  more  shining  than  above;  prosternal  lobe  subtruncate, 
intercoxal  process  moderately  broad,  acute  at  tip,  proplenrse  granulate,  finely 
pubescent;  metasternum  at  sides  roughly  transversely  strigoSe.  Abdomen  finely 
])unctate,  s]>arse  along  the  middle,  closer  along  the  sides  and  dense  at  the  side  of 
the  first  segment;  vertical  portions  of  the  segments  finely  pubescent,  apical 
segment  truncate;  pygidium  coarsely  punctured  and  with  a median  carina  pro- 
jecting strongly  at  apex  ; claws  dissimilar  on  the  feet.  Length  .35  inch. ; 9 mm. 

Male. — Prosternum  densely  punctured  between  the  coxse,  more 
sparsely  in  front;  surface  not  pubescent;  first  and  second  ventral 
segments  each  with  a deep,  smooth  median  groove,  that  on  the  second 
segment  extending  nearly  to  the  suture  posteriorly ; anterior  tibite 
very  distinctly  mucronate,  middle  less  distinctly,  posterior  tibiie  sim- 
ple ; claws  of  middle  and  anterior  tarsi  cleft  so  close  to  the  tip  as  to 
seem  bifid,  posterior  claws  broadly  toothed  at  base. 

Female. — This  sex  has  not,  with  certainty,  been  found  among  my 
specimens.  It  probably  differs  from  the  male  in  the  manner  usual 
in  the  group. 

In  well  preserved  specimens  of  this  species  the  underside  of  the 
body  is  more  or  less  clothed  along  the  side  with  a whitish  efflores- 
cence, whereby  the  pubescence  is  made  more  evident,  and  apparently 
more  dense. 

This  species  closely  resembles  pensus  and  auxins,  so  that  it  will  be 
difficult  to  separate  the  females,  especially  from  the  latter,  but  the 
ventral  characters  of  the  male  will  enable  it  to  be  at  once  recognized.

not  closely  punctate,  very  little  pubescent,  sides  of  metasternum  densely,  not 
coarsely,  asperate.  Abdomen  moderately  closely  punctate,  less  so  at  middle, 
dense  at  sides  of  first  segment;  last  segment  truncate,  vertical  portion  of  ventral 
segments  sparsely  ptibescent;  pygidium  coarsely  punctate,  the  median  carina 
produced  at  apex;  claws  dissimilar  on  the  feet.  Length  .30 — .45  inch.  ; 7.5 — 
11.5  mm. 

Male. — Front  more  densely  punctured,  usually  greenish.  Proster- 
nnni  densely  punctured  between  the  coxse,  more  sparsely  in  front, 
not  hairy  ; fir.st  ventral  segment  vaguely  depressed  along  its  middle, 
but  not  smooth,  the  second  with  a smooth,  deep  impression  extending 
two-thirds  to  the  suture;  anterior  tibise  feebly  mucronate,  middle 
and  posterior  tibite  simple;  claws  of  anterior  and  middle  feet  cleft 
at  apex,  apparently  bifid,  posterior  claws  cleft  near  base,  forming  a 
short,  acute  tooth. 

Female. — Head  somewhat' cupreous,  less  densely  punctate.  Ven- 
tral segments  simple;  tibiie  not  mucronate;  claws  broadly  toothed 
at  basal  half.  ■ 

The  color  of  this  species  is  remarkably  constant,  varying  but  little 
from  olivaceous,  becoming  but  slightly  green  or  plumbeous,  resem- 
bling closely  both  pensus  and  Blanchardi,  from  either  of  which  ref- 
erence must  be  had  to  the  male  characters  for  separation,  although 
the  carina  of  the  hind  angles  of  the  thorax  is,  in  both  sexes,  stronger 
and  more  arcuate  than  in  any  species  related  here.  In  my  cabinet 
a male  specimen  from  an  unknown  locality  agrees  in  all  particulars, 
except  that  the  hind  claws  have  the  same  form  as  on  the  middle  and 
front  feet,  and  the  angular  carina  is  much  less  distinct.  While  it 
may  represent  a different  species,  it  seems  preferable  to  allow  it  to 
pass  with  mere  mention. 

A careful  examination  of  the  types  of  torpidus  and  gravis  })rove 
them  identical  with  the  present  species.  Both  were  founded  on 
female  specimens. 

Hab. — Massachusetts  and  New  Hampshire;  westward  to  Colorado.

on  each  side  a fovea,  lateral  depression  well  marked;  surface  transversely  stri- 
gose,  but  not  coarsely,  with  finer  punctures  in  the  intervals;  scutellum  trans- 
versely carinate;  elytra  sinuate  behind  the  humeri,  slightly  broadened  behind 
the  middle,  apices  suhacutely  rounded,  serrulate,  disc  flattened  at  middle,  some- 
times with  a vague  costa,  basal  fovea  moderate,  suture  elevated  behind  the  mid- 
dle, surface  densely  imhri cate-granulate  ; body  beneath  more  shining  than  above  ; 
prostenial  lobe  snhtruucate,  vaguely  emarginate,  intercoxal  j)rocess  broad,  nearly 
])arallel,  acute  at  tip,  vaguely  impressed  longitudinally,  propleurse  densely  punc- 
tate and  rather  densely  clothed  with  whitish  pubescence,  sides  of  metasternum, 
metapleuraj  and  outer  side  of  coxal  plates  densely  punctate  and  with  whitish 
pubescence.  Abdomen  moderately  closely  punctate,  at  sides  of  first  ventral 
strigose,  last  segment  oval  at  tip,  vertical  portion  of  the  ventral  segments  densely 
clothed  with  whitish  pubescence,  except  sometimes  on  the  second  segment;  py- 
gidium  coarsely  punctate,  the  median  carina  prolonged  at  apex  ; claws  variable 
on  the  feet.  Length  .32 — .40  inch.;  8 — 10  mm. 

Male. — Front  less  irregular,  the  median  impression  well  defined, 
but  with  feeble  traces  of  oblique  depressions;  anterior  and  middle 
tibite  feebly  mucronate,  posterior  tibiae  simple  ; claws  of  anterior  and 
middle  tarsi  cleft  very  near  the  apex,  nearly  bifid,  posterior  claws 
acutely  cleft,  but  less  close  to  apex  ; first  ventral  segment  convex  at 
middle,  the  second  with  a deep,  smooth,  abruptly  formed  groove  ex- 
tending from  the  finst  suture  more  than  half  to  the  second. 

Female. — Front  more  irregular,  the  median  groove  less  sharply 
defined,  the  oblique  depressions  more  evident ; tibiae  not  mucronate  ; 
claws  similar  on  all  the  feet,  cleft  behind  the  apex,  forming  an  acute 
tooth.  Ventral  segments  convex  at  middle,  not  grooved. 

Variaiiona. — Two  well  marked  varieties  may  be  indicated  based 
on  color,  between  which  there  are,  however,  distinct  intermediates. 

Var.  acutipennis  Mann. — Color  deep  blue,  becoming  blue-black  in 
one  direction,  or  slightly  olivaceous  in  the  other. 

This  form  is  usual  in  the  more  southern  regions,  although  my 
darkest  specimen  is  from  Massachusetts,  as  well  as  that  intermediate 
between  the  blue  form  and  the  next  variety. 

Var. . — Color  olivaceous,  the  thorax  somewhat  brassy. 

This  variety  seems  confined  to  the  more  northern  regions  of  the 
country  ; in  fact,  all  I have  seen  are  from  Massachusetts. 

Habits. — j\Ir.  Blanchard  states  that  he  has  taken  the  acutipennis 
form  on  the  foliage  of  Oak  shrubs,  the  other  on  foliage  of  Poplar 
si)routs.  These  observations  do  not  give  any  positive  indication  of 
the  wood  into  which  they  bore.

While  I have  united  the  two  forms  with  some  reluctance  I will 
admit  that  I have  been  unable  to  find  any  structural  character  sepa- 
rating them.  The  extremes  are  quite  distinct  in  color,  but  the  inter- 
mediates form  a complete  union. 

Hah. — Massachusetts  to  Kansas,  Florida  and  Texas. 

C'oiiosii  Lee. — Elongate,  somewhat  depre.s.sed,  slightly  concave  on  the 
dorsal  line  when  viewed  laterally,  color  golden-green,  moderately  shining,  sides 
of  thorax  and  elytral  vitte  piibescent.  Antennse  rather  short,  not  attaining  the 
middle  of  the  thorax,  feneous,  serrate  from  the  fourth  joint.  Head  broadly 
concave,  more  deeply  impressed  along  the  middle,  a tubercle  each  side  of  middle 
of  front,  a rather  deep  transverse  groove  above  the  base  of  clypeus,  between  the 
antennal  fovea,  surface  very  coarsely  punctate,  occiput  slightly  strigose.  Thorax 
one-third  wider  than  long,  slightly  narrowed  at  base,  sides  feebly  arcuate,  mar- 
gin sinuous,  hind  angles  rectangular,  with  a slight  obtuse  elevation  in  the  male 
and  a feeble  carina  in  the  female;  disc  moderately  convex,  with  a broad  and 
rather  deep  groove  extending  from  base  to  apex,  sides  obliquely  depressed,  sur- 
face punctate  and  rather  coarsely  strigose,  except  on  a space  each  side  of  median 
groove,  broadly  clothed  with  yellowish  white  pubescence  at  sides:  scutellum  not 
transversely  carinate:  elytra  slightly  sinuate  behind  the  humeri,  feebly  broad- 
ened behind  the  middle,  apices  obtusely  rounded,  serrulate,  disc  comewhat  flat- 
tened. with  a very  well  defined  costa  extending  from  the  humeri  very  nearly  to 
apex,  in  latter  region  slightly  sinuous  ; surface  pubescent,  but  forming  a distinct 
vitta  within  each  costa,  extending  from  the  feeble  basal  depression  to  apex  and 
near  the  latter  region  twice  interrupted,  punctuation  dense  and  fine  between  the 
cost*,  coarser  exterior  to  them  ; body  beneath  more  shining  than  above;  proster- 
uum  sparsely  punctate  in  both  sexes,  the  lobe  emarginate,  iutercoxal  process 
broad,  obtusely  pointed  at  apex,  propleui-*  densely  punctate,  somewhat  strigose. 
distinctly  pubescent;  metasternum  at  middle  sparsely  punctate,  at  sides  more 
densely  and  finely  and  with  the  episterna  and  outer  half  of  coxal  plate  pubes- 
cent. Abdomen  very  sparsely  punctate  at  middle,  first  and  second  segments  with 
a densely  punctured  and  pubescent  stripe  at  a distance  from  the  lateral  margin, 
the  next  three  segments  with  a pubescent  triangular  spot  at  sides,  the  lateral 
marginal  line  on  the  first  two  segments  indistinct  and  sinuous,  the  vertical  por- 
tions of  the  segments  densely  pubescent;  pygidium  with  a feeble  carina,  which 
does  not  project ; claws  cleft,  forming  a broad  tooth  in  both  sexes.  Length  .38 — 
.44  inch. ; 10-  11  mm. 

Sexual  characters. — The  sexes  are  differentiated  with  some  difficulty. 
I observe  that  the  male  has  the  dorsum  less  depressed  and  the  carina 
of  the  hind  angles  merely  a feeble  elevation. 

Very  few  specimens  have  been  seen,  and  no  variations  observed. 

This  species  and  cavatus  are  of  an  entirely  different  facies  from  the 
remainder  of  our  species,  being  of  the  type  more  commonly  observed 
in  Mexico.  It  has  been  supjiosed  to  be  identical  with  perkicklns 
Gory,  an  opinion  which  Crotch  thought  not  well  founded. 

Occurs  in  Arizona  and  southern  New  Mexico  (Snow).

jecting. Length  .36 — .,56  inch.  ; 9 — 14.5  mm. 

Sexual  characters. — The  males  may  be  known  by  their  smaller  size, 
more  slender  form,  the  abdomen  less  dilated  beyond  the  sides  of  the 
elytra,  the  elytral  costa  better  defined,  and  the  tuberosity  in  the  hind 
angles  of  the  thorax  less  so.  There  are  no  ventral  characters.  The 
claws  are  cleft  quite  near  the  tip,  forming  an  acute  tooth  in  the  front 
and  middle  claws,  more  broadly  toothed  on  the  posterior.  The  tibite 
are  not  mucronate.  The  female  claws  do  not  differ. 

Variations. — When  carefully  collected  specimens  are  at  hand  the 
elytral  vitta  extends  from  the  humerus  two-thirds  to  apex,  forming 
at  its  end  a denser  spot,  on  each  side  there  is  a short  pubescent  vitta 
opposite  the  end  of  the  former  and  a short  distance  in  the  front  of 
the  apex  a small  pubescent  spot.  By  abrasion  the  greater  ]>art  of 
the  vitta  is  often  lost,  and  there  then  remains  a basal  spot,  the  denser 
end  of  the  vitta  and  the  ante-apical  spot.

claws  broadly  toothed.  Length  .50  inch.;  12.5  mm. 

In  the  five  specimens  examined  no  sexual  differences  have  been 
observed. 

Tlie  posterior  tibite  have  a form  wliich  has  not  been  observed  in 
any  other  of  our  species.  Near  the  apex  the  tibia  is  rather  abruptly 
narrowed.  The  fringe  of  short  bristly  hairs  which  is  observed  along 
the  posterior  edge  of  the  tibise  in  all  the  species  in  a varying  degree 
is  here  present,  but  ends  abruptly  at  the  point  at  which  the  tibia  is 
narrowed. 

The  facies  of  this  sjiecies  is  so  unlike  the  style  of  those  of  our 
fauna,  that  1 remained  for  some  time  in  doubt  as  to  the  correctness 
of  the  locality.  Recently,  however,  a specimen  has  been  sent  me 
from  the  National  Museum  removing  all  doubts.

Variations. — Beyond  the  color  nothing  has  been  observed.  The 
pubescent  spots  may  be  abraded,  although  they  seem  unusually  per- 
sistent. The  smaller  spots,  jiosterior  to  the  base,  form  on  the  elytra 
an  elongate  hexagon.

In  the  two  females  before  me  the  underside  is  purplish  black,  in- 
cluding the  legs,  while  all  the  males  are  brassy. 

Variations. — In  the  males  the  thorax  is  green,  inclining  somewhat 
to  purplish  occasionally,  while  the  two  females  are  deep  purple.  The 
sides  of  the  elytra  in  both  sexes  are  cupreous,  sometimes  seneous  in 
the  males,  the  intermediate  space  green,  varying  to  purple  in  the 
male,  and  ])urple  in  the  female. 

For  this  species  and  one  closely  allied  from  Mexico,  Mr.  Water- 
house  (Biol.  Cent.  Am.  vol.  iii,  ])t.  1,  p.  50)  has  suggested  the  generic 
name  Eng^jaulus,  which  he  separates  from  Agrilm  by  the  convex 
front,  and  the  mouth  consequently  more  inferior,  and  the  short  first 
joint  of  the  posterior  tarsi.  In  a study  of  our  species  these  charac- 
ters are  shown  to  have  no  value,  as  will  be  seen  by  an  examination 
of  the  form  of  the  head  in  the  species  near  which  pidchellus  is  placed 
— Walsinghami,  obolinus  and  mntieus.  While  the  first  joint  of  the 
hind  tarsus  is  short,  it  is  still  equal  in  length  to  the  next  two,  so  that 
when  conqiared  with  these  or  with  the  tibia  the  length  is  scarcely 
less  than  in  very  many  species  before  me.  From  the  fact  that  there 
are  no  valid  characters  for  retaining  Engyavlus  apart  from  Agriius 
our  species  is  returned  to  the  latter  genus. 

Hab. — Arizona  and  Colorado. 

A.  ol»oliiiii»«  Lee. — Facies  rather  robust,  color  from  seiieo-cupreous  to  i)liini- 
beous,  feebly  shining,  sparsely  finely  jnibescent.  Antenna*  short,  scarcely  attain- 
ing the  niiddle  of  thora-x,  seneous,  serrate  from  the  fourth  joint;  front  concave, 
coarsely  closely  punctured.  Thorax  very  little  wider  than  long,  sides  feebly 
arcuate,  margin  sinuate,  hind  angles  rectangular  without  trace  of  carina,  disc 
convex,  with  a median  impression  extending  from  base  to  apex,  widest  poste- 
riorly, lateral  oblique  depression  moderate,  surface  punctate,  rather  coarsely  not 
closely,  without  strigosity  ; scutelluin  without  trace  of  transverse  carina  ; elytra 
feebly  sinuate  behind  the  humeri,  slightly  broadened  behind  the  middle,  apices 
obtuse  without  serrulation,  disc  moderately  convex,  with  feeble  basal  depressions 
and  two  very  vague  costte  on  each  side,  surface  moderately  closely  imbricately 
punctate;  body  beneath  scarcely  more  shining  than  above;  prosternal  lobe 
broadly  emarginate,  the  intercoxal  process  broad  and  very  obtuse  at  lip:  pro- 
pleurpe  coarsely  punctate  and  slightly  strigose ; metasternum  densely  and  more 
finely  punctate,  slightly  strigose.  Abdomen  finely  putictate,  sparsely  at  middle,

pygidiuin  coarsely  i)unctate,  the  carina  not  projecting;  claws  cleft  near  the  tip, 
forming  a broad  tooth.  Length  .32 — ..36  inch. ; 8 — 9 inm. 

Male. — Prosteriiuni  rather  Hat,  densely  j)unctate,  finely  pubescent. 

Female. — Prosteriiuni  more  convex,  more  sparsely  punctate  and 
shining,  not  pubescent. 

Variations. — Nothing  has  been  observed,  except  in  the  color. 

The  elytra  have  been  described  as  serrulate,  but  this  is  an  error 
of  observation,  from  the  fact  that  the  sides  of  the  last  ventral  are 
rather  strongly  serrate,  a rather  unusual  character  not  heretofore 
recorded  in  our  species. 

Hab. — Kansas,  Texas,  Arizona  and  southern  California  (Ulke). 

A.  nintieus  Lee. — Form  rather  robust,  color  ])liimheous,  or  with  slight 
bluish  lustre.  Anteniiffi  scarcely  attaining  the  middle  of  the  thorax,  piceous, 
serrate  from  the  fourth  joint;  head  convex,  front  alone  impressed  along  the 
middle,  the  surface  densely  punctate.  Thorax  nearly  square,  sides  slightly  sin- 
uous, margin  sinuate,  hind  angles  slightly  everted  and  with  a feeble  straight 
carina,  disc  convex,  a vague  median  depression  near  the  base,  lateral  depressions 
feeble,  surface  densely  punctate  with  a finely  strigose  arrangement;  elytra  sin- 
uate behind  the  humeri,  very  feebly  dilated  behind  the  middle,  apices  slightly 
sinuate,  not  serrulate,  disc  slightly  flattened,  basal  depressions  feeble,  surface 
densely,  finely,  imhricately  granulate  ; scutellum  not  transversely  carinate ; body 
beneath  more  shining  than  above;  prosternal  lobe  truncate,  or  slightly  emar- 
ginate,  intercoxal  process  broad,  slightly  broader  at  apex  and  emarginate;  pro- 
pleurse  and  sides  of  metasternum  densely  punctate,  the  latter  slightly  strigose. 
Abdomen  finely  not  closely  punctate,  more  closely  at  the  sides  and  on  the  first 
segment,  vertical  portion  of  segments  pubescent,  but  not  conspicuously;  last 
segment  very  finely  serrulate  at  sides  near  apex  ; pygidium  punctate,  indistinctly 
carinate  at  middle;  claws  cleft,  the  lower  portion  forming  an  acute  tooth.  Length 
.28 — .35  inch. ; 7 — 9 mm. 

Male. — Prosternum  more  densely  jtunctured  and  subopaque,  pu- 
bescent; metasternum  flat,  first  ventral  segment  vaguely  sulcate  at 
middle,  densely  punctate,  slightly  pubescent. 

Female. — Prosternum  less  closely  jninctate  and  less  pubescent  ; 
metasternum  less  flattened  ; fir.st  ventral  convex  at  middle. 

Variations. — This  species  seems  remarkably  constant  in  form  and 
color,  varying  only  in  size.  The  carina  of  the  hind  angles  is  at  most 
feeble  and  specimens  occur  without  any  trace  of  it. 

Hab. — Kansas  to  Texas. 

A.  jaeobiims  ii.  sji. — Form  cylindrical,  moderately  robust  iu  facies,  faintly 
cupreous,  inclining  to  plumbeous,  subopaque.  Anteunse  rather  short,  scarcely 
attaining  the  middle  of  the  thorax,  piceous,  slightly  cupreous,  serrate  from  the 
fourth  joint;  head  convex,  with  a slight  median  depression  from  the  occiput  to

the  clypeus.  densely  and  rather  roughly  punctate,  sparsely  pubescent.  Thorax 
very  little  wider  than  long,  sides  feebly  arcuate,  margin  sinuate,  hind  angles 
rectangular,  with  a distinct,  nearly  straight  carina,  disc  convex,  without  median 
dorsal  imjiression,  lateral  depression  feeble,  surface  rather  roughly  granulately 
sculptured:  scutellum  rather  uneven,  but  without  distinct  transverse  carina: 
elytra  slightly  sinuate  behind  the  humeri,  then  nearly  parallel,  gradually  nar- 
rowed at  apical  third,  apices  rounded,  indistinctly  serrulate,  disc  slightly  flat- 
tened with  a vague  costa  each  side,  between  which  and  the  suture  the  surface,  is 
somewhat  concave,  basal  depressions  very  feeble,  surface  rather  densely  granu- 
late, more  finely  in  the  dorsal  groove,  surface  sparsely  clothed  with  short,  fine 
pubescence,  apparently  closer  in  the  groove,  giving  an  appearance  of  a vitta; 
body  beneath  more  brassy  than  above;  prosternal  lobe  rounded,  intercoxal  pro- 
cess broad,  with  its  apex  squarely  truncate,  i)ropleurfe  densely  granulate-punctate ; 
metasternum  at  sides  closely  punctate.  Abdomen  ratber  coarsely  and  moder- 
ately closely  punctate,  very  little  more  densely  at  the  sides,  surface  sjjarsely 
pubescent,  vertical  portion  of  the  segments  s[iarsely  pubescent;  last  segment 
finely  serrulate  at  the  sides  near  apex;  pygidium  coarsely  punctate,  feebly  cari- 
nate; claws  dissimilar  in  the  sexes.  Length  .24 — .28  inch.;  6 — 7 mm. 

Male. — Prosternum  densely  punctate  and  with  silken  hair,  which 
extends  along  the  middle  of  the  metasternum  ; first  two  ventral  seg- 
ments slightly  flattened,  a little  more  pubescent  along  the  middle  ; 
claws  cleft  close  to  the  apex,  almost  bifid. 

Female. — Prosternum  less  densely  jiunctate  and  less  hairv  ; ventral 
segments  convex  at  middle ; claws  cleft  at  middle,  forming  an  acute 
tooth. 

No  variations  have  been  observed. 

The  structural  characters  of  this  species  will  enable  it  to  be  readily 
))laced  among  those  with  more  or  less  serrulate  last  ventral  segment, 
non-carinate  scutellum,  elytra!  apex  nearly  without  serrulation  and 
hind  angles  of  thorax  but  feebly  carinate. 

Hab. — San  Diego,  Cal. 

.4.  polituft  Say. — Moderately  elongate,  slightly  depre.ssed  on  the  dorsum, 
color  variable  from  rather  bright  brassy  to  cupreous,  purplish,  plumbeous,  bluish 
or  greenish,  moderately  shining.  Antennse  rather  short,  not  reaching  the  mid- 
dle of  the  thorax,  variable  in  color,  serrate  from  the  fourth  joint;  head  slightly 
convex,  a feeble  median  depression  from  the  occiput  to  the  middle  of  the  front; 
front  coarsely  granulate,  occiput  strigo.se.  Thorax  one-third  wader  than  long, 
sides  slightly  arcuate,  margin  feebly  .sinuate,  hind  angles  feebly  carinate  in  both 
sexes,  disc  convex  with  two  feeble  median  depressions,  one  near  base  and  one

transversely  strigose,  punctate  between  the  strigte  ; scutellum  transversely  cari- 
nate ; elytra  sinuate  behind  the  humeri,  dilated  behind  the  middle,  more  notably 
in  the  female,  slightly  sinuate  near  the  apices,  which  are  rounded  and  serrulate; 
disc  slightly  flattened,  sometimes  with  a very  vague  costa  in  the  male,  basal  de- 
jn-essions  feeble,  surface  closely  iinbricate-granulate ; body  beneath  more  shinitig

moderate,  acute  at  tip,  propleiiraj  densely  punctate  granulate  ; inetaiileurse  rugose, 
soniewliat  strigose.  Al)domen  finely  punctured  and  finely  transversely  strigose. 
more  densely  at  the  sides,  especially  on  the  first  two  segments,  vertical  portion 
of  the  segments  sparsely  pubescent;  last  ventral  segment  finely  serrulate  at  sides 
near  the  apex:  pygidium  coarsely  punctate,  feebly  carinate  along  the  middle: 
claws  dissimilar  in  the  sexes.  Length  .20 — ..34  inch.;  5 — 8.5  mm. 

Male. — Front  more  densely  punctured  and  flatter;  prosternuin 
densely  punctured,  hairy  ; claws  of  anterior  and  middle  feet  cleft 
near  the  apex,  nearly  bifld,  posterior  claws  cleft  at  middle,  forming  a 
broad  tooth. 

Female. — Front  more  shining,  more  convex  ; prosternuin  less  punc- 
tate, with  short,  sparse  hair;  claws  of  all  the  feet  cleft  at  middle, 
forming  a tooth. 

Variations. — In  recent  specimens  the  surface  is  clothed  with  a very 
tine,  short  pubescence,  which  gives  them  a pruinose  aspect,  the  vast 
majority  of  cabinet  specimens  have  no  {luhescence. 

The  differences  of  color  have  given  rise  to  several  names  which  do 
not  seem  to  he  worthy  of  retention,  even  as  varietal  names  inasmuch 
as  the  intergrading  of  color  is  so  gradual  as  to  render  it  impossible 
to  separate  them. 

A.  cupreolm  Lee.  was  founded  on  a uni(|ue  of  rather  larger  size 
than  usual,  jeneo-cupreous  in  color. 

.4.  poliius  Say,  is  the  more  common  form  of  cupreous  color. 

A.  pl'iimbeus  Vec.  founded  on  specimens  of  a dull  leaden  color; 
these  intergrade  with  the  cupreous  and  the  green  forms. 

^1.  desertiis  ||  Lee.  was  founded  on  a single  specimen  of  smaller 
size  and  more  brilliant  color  than  the  preceding  forms.  The  sculp- 
ture is  less  dense.  These  may  be  either  bright  brassy,  blue  or  green. 

Habits. — This  species  lives  on  Willows  in  whatever  part  of  the 
country  it  is  found. 

Hab. — Canada  and  the  New  England  States  westward  to  the  Pa- 
eifle  coast,  Kansas,  Colorado,  New  Mexico,  Arizona,  Nevada  and 
throughout  California.  In  the  Atlantic  region  it  extends  as  far  south 
as  Maryland,  but  no  specimens  have  been  seen  from  any  of  the 
southern  Atlantic  or  Gulf  States  nor  from  the  region  south  of  the 
Ohio  River. 

.4.  fstllax  Say. — Form  moderately  elongate,  dark  olivaceous,  sometimes 
greenish,  each  elytron  with  three  small  pubescent  spots.  Anteniiie  slender  and 
long,  reaching  to  the  hind  angles  of  the  thorax,  usually  greenish,  serrate  from 
the  fourth  joint;  head  rather  flat,  with  a feeble  median  imjiression  from  occiput 
to  clypeus,  front  granulate  and  alutaceous,  occii>ut  slightly  strigose.  Thorax

very  little  wider  than  lon.s,  arcuate  in  front,  slightly  sinuate  in  front  of  the 
hind  angles,  which  are  acutely  rectangular  and  with  a sharply  defined  straight 
Carina,  margin  feehly  sinuate;  disc  convex,  with  a vague  median  depression  pos- 
tei'iorly,  lateral  ohliqne  depressions  moderate,  surface  transversely  strigose  with 
fine,  distant  imnctnres  between  ; scuteilum  transversely  carinate ; elytra  slightly 
sinuate  behind  the  humeri,  feehly  dilated  behind  the  middle,  ajiices  rounded 
and  serrulate,  disc  slightly  flattened  with  a very  vague  costa,  basal  depression 
feeble,  surface  imbricate,  on  each  elytron  three  round  pubescent  spots,  basal, 
ante-median  and  one-third  from  apex;  body  beneath  more  hi'assy  tlian  above; 
prosternal  lobe  entire  or  snhtruncate,  intercoxal  process  gradually  narrowed, 
acute  at  apex,  itroplenrpe  scabrous  in  sculpture,  sparsely  pube.scent;  metasternum 
subgranulate  and  transver.sely  strigose.  Abdomen  sparsely  pui}ctate  at  middle 
and  alutaceous,  at  sides  somewhat  strigose.  vertical  portion  of  the  segments 
sparsely  pubescent;  jiygidium  coarsely  punctate,  carinate  at  middle  anteriorly; 
claws  dissimilar.  Length  .16 — .24  inch.;  4 — 6 mm. 

Male. — Head  Hatter,  more  oitaque  and  more  granulate,  usually 
green  ; prosternum  densely  punctate  and  with  rather  long  pubes- 
cence ; metasternum  Hat,  densely  punctured  ; first  two  ventral  seg- 
ments longitudinally  impressed  at  middle,  their  entire  length,  sparsely 
pubescent ; claws  of  anterior  tarsi  cleft  very  near  the  apex,  nearly 
bifid,  middle  and  posterior  claws  cleft  at  middle,  forming  a broad 
tooth  ; anterior  and  middle  tibire  slightly  mucronate. 

Female. — Head  cujireous  or  bras.sy,  less  distinctly  sculptured,  more 
convex  ; prosternum  sparsely  punctate,  not  hairy  ; metasternum 
slightly  convex,  simply  {)unctate ; first  two  ventral  segments  convex 
at  middle ; claws  cleft  at  middle,  forming  a broad  tooth  ; tibife  not 
mucronate. 

Variations. — Slight  variations  in  color  will  be  seen  as  usual  in  the 
dark  species.  The  median  impression  of  the  thorax  may  consist  of 
an  anterior  fovea  or  a feebly  impressed  median  line. 

When  the  pubescent  spots  are  removed  by  abrasion,  this  species, 
especially  the  smaller  specimens,  greatly  resembles  egenus,  and  great 
care  must  be  used  in  separating  them,  but  the  serration  of  the  an- 
tennae is  quite  different  in  the  two  species. 

Of  its  habits  I know  nothing. 

Hab. — Canada  southward  to  Louisiana  and  Texas,  westward  to 
Nebraska. 

A.  obsoletOgiittRtiiS  Gory. — Form  slender,  elongate,  color  brassy  black 
or  dark  olivaceous,  feebly  shining,  each  elytron  with  three  pubescent  spaces,  the 
middle  one  elongate.  Antennae  slender,  passing  the  middle  of  the  thorax,  more 
or  less  aeneous,  serrate  from  the  fourth  joint;  head  coarsely  punctate,  occiput 
strigose.  front  flat,  with  a depression  at  its  upper  part  in  chevron.  Thorax  very

the  apex,  lateral  oblique  depressions  feeble,  surface  transversely  strigose  and 
punctate  between  the  strigfe ; scutellum  transversely  carinate;  elytra  slightly 
sinuate  behind  the  humeri,  feebly  dilated  behind  the  middle,  apices  rounded  and 
serrulate,  disc  slightly  depressed,  a very  vague  costa  each  side,  basal  depression 
moderate,  on  each  side,  within  the  costa,  are  three  t)nbescent  spots,  OTie  at  base, 
an  elongate  spot  in  front  of  middle,  a smaller  oval  spot  one-third  from  apex, 
usually  also  a small  spot  exterior  to  the  costa  near  the  end  of  the  middle  spot, 
surface  rather  closely  imbricate-granulate  : body  beneath  more  shining  than 
above;  prosternal  lobe  rather  deeply  emarginate,  intercoxal  process  parallel  be- 
tween the  coxjE,  acute  at  tip,  propleurse  closely  punctate;  metasternum  at  sides

portion  of  segments  not  conspicuously  pubescent;  pygidium  coarsely  punctate, 
carinate  at  middle;  claws  cleft  near  the  middle,  forming  a broad  tooth.  Length 
.'24 — .32  inch. ; 6—8  mm. 

Male. — Front  usually  green,  more  densely  punctate;  prosternuin 
densely  punctured  and  pubescent,  anterior  portion  of  nietasternum 
hairy  ; anterior  and  middle  tibite  distinctly  mucronate ; first  and

Female. — Front  less  closely  punctate,  ajneous  or  cupreous;  jtro- 
sternum  more  shining,  not  hairy;  tibim  not  mucronate;  ventral 
segments  simply  punctate. 

Variations. — No  variation  of  moment  has  been  observed.  Badly 
preserved  s|)ecimens  are  often  without  spots,  but  the  elongate  narrow 
form  of  the  insect  will  make  it  easily  known.’ 

This  species  is  especially  notable  in  the  long  slender  legs.  The 
hind  tarsi  are  especially  elongate,  being  longer  than  the  tibia,  the 
first  joint  longer  than  half  the  tibia. 

Habits. — Found  on  the  foliage  of  Oak  shrubs.

coarsely  punctate,  indistinctly  carinate  ; claws  broadly  toothed  at  middle.  Length 
.18— .20  inch. ; 4.5 — 5.5  mm. 

Male. — Prosternuin  densely  jumctate,  finely  pubescent,  the  pubes- 
cence extending  on  the  front  of  the  inetasternuin  ; first  ventral  seg- 
ment slightly  flattened  at  middle,  not  pubescent ; anterior  and  middle 
tihiie  distinctly  mucronate. 

Female. — Unknown. 

This  species  is  not  especially  conspicuous  among  those  with  ornate 
elytra.  With  the  form  of  fallax  or  egenus,  the  markings,  when  per- 
fect, resemble  those  of  obsoleto-guttatiis,  and  from  any  of  them  the 
structural  characters  either  of  the  antennae,  legs  or  prosternum  will 
.separate.

Texas,  probably  at  Waco.

segments  piihescent;  pygidimn  sparsely  punctate,  finely  (;arinate  along  the  mid- 
dle; claws  broadly  toothed  at  base.  Length  .14  inch. ; 3.5  mm. 

Sexual  characters. — The  only  points  noticed  in  the  nninerons  speci- 
mens examined  are  found  in  the  more  opafpieand  sctmewliat  nigulo.se 
prosternum  of  the  male,  while  it  is  sjiarsely  punctate  and  smoother 
in  the  female. 

No  variations  have  been  olxserved,  the  markings  .seeming  very 
constant.  In  some  specimens  there  will  be  observed  a golden  hue 
about  the  margins  of  the  pubescent  spaces. 

Hab. — Southwestern  Texas,  no  precise  locality  known. 

\,  n.  sp. — Form  oblong,  subcylindrical,  cupreo-ffineous,  moder- 

ately shining,  elytra  with  faint  siibsutural  pubescent  vitta.  Antennte  piceous, 
faintly  bronzed,  attaining  the  middle  of  the  thora.x.  serrate  from  the  fourth 
joint;  head  convex,  with  a faint  median  impression  from  the  occijiut  to  the  cly- 
peus,  coarsely  not  closely  i)unctate.  Thorax  nearly  square,  sides  feebly  arcuate, 
margin  .straight,  deflexed  in  front,  hind  angles  rectangular,  without  trace  of 
Carina,  di.sc  convex,  without  depressions  either  at  middle  or  sides,  not  concave 
along  the  margin,  surface  ]mnctate  along  the  middle,  vaguely  strigose  at  the 
sides  ; scutellum  indistinctly  carinate  ; elytra  slightly  sinuate  behind  the  humeri 
and  dilated  behind  the  middle,  ai>ices  rounded,  finely  serrulate,  disc  convex,  the 
basal  depressions  feeble,  surface  rather  coarsely  and  roughly  imbricate  with  a 
sparsely  pubescent  subsutural  vitta  extending  from  the  base  iiearly  to  the  apex  ; 
body  beneath  seneous;  prosternum  acutely  but  not  deeply  emarginate  at  mid<lle, 
not  wide  between  the  coxa,  tip  not  acute,  propleurre  |)unctate,  sparsely  pubes- 
cent; metasternum  at  sides  transversely  strigose,  somewhat  reticulate  in  cei  tain 
lights.  Abdomen  sparsely  punctate,  with  distant  striga*  at  the  sides  of  the  first 
two  segments,  suhreticulate  in  appearance,  the  posterior  edge  of  the  second,  and 
to  a less  degree  the  third  segment,  prolonged  at  middle  in  a short  laminate  pro- 
ce,ss,  which  occupies  one-third  the  width  of  the  segment;  claws  toothed  near  the 
base.  Length  .13  inch.;  3.5  mm. 

Unfortunately,  tlie  two  specinieu.s  before  me  of  tins  species  present 
no  special  characters  of  a sexual  nature.  The  prosteruum  is  some- 
what rugose  and  slightly  pubescent,  and  the  first  ventral  roughened 
at  middle  of  base,  and  from  these  feeble  characters  they  are  assumed 
to  be  males. 

The  most  curious  character  observed  is  in  the  v'^entral  segments, 
and  seems  unique  in  the  genus.  The  posterior  edge  of  the  second 
ventral  segment  is  free  and  slightly  prolonged  in  an  arcuate  manner 
over  the  next  .segment.  The  same  in  a less  degree  is  observed  on  the 
third  segment.  This  may  prove  to  be  a male  peculiarity. 

The  sculpture  of  the  disc  of  thorax  viewed  in  certain  lights  seems 
reticulate,  as  in  some  Anthaxia,  and  the  elytral  sculpture  very 
coarse  for  so  small  a species.

Hub. — New  Mexico,  no  ])recise  region  known. 

A.  blaiidiiK  n.  sp. — Rather  robust,  subcyliiidrical,  slightly  narrowed  behind,

base  to  near  the  apex.  Anteniue  passing  slightly  the  middle  of  the  thorax, 
seneons,  serrate  from  the  fifth  joint;  head  slightly  convex,  a feeble  median  im- 
pression from  the  occiput  to  the  clypens.  the  latter  broad  at  base,  surface  rather 
coarsely  punctate  and  obliquely  strigose.  Thorax  a little  wider  than  long,  sides 
regularly  arcuate,  slightly  sinuate  near  the  hind  angles,  which  are  rectangular 
and  without  trace  of  a carina,  lateral  margin  sinuous,  disc  convex,  without  trace 
of  median  sulcus,  lateral  oblique  impression  feeble,  surface  rather  closely  punc- 
tate with  feeble  obliijue  strigse,  sides  pubescent,  more  broadly  behind  ; scutellum 
transversely  carinate;  elytra  very  slightly  sinuate  at  middle  and  slightly  broad- 
ened. apices  rounded,  serrulate,  disc,  convex,  basal  depression  feeble,  surface 
rather  coarsely  imbricate  and  with  a vitta  of  whitish  pubescence  from  the  base 
to  the  apex  close  to  the  suture;  body  beneath  cupreo-teneous ; prosternal  lobe 
truncate,  with  a feeble  emargination  at  middle,  the  inten'.oxal  proc^ess  narrowed 
from  base  to  apex,  the  tip  obtuse,  propleurje  punctate,  with  scale-like  white  hairs 
and  effloresence ; metasternum  at  sides  irnbricately  sculptured  and  with  the

segments,  clothed  along  the  sides  with  whitish  pubescence,  vertical  portion  of 
first  segment  with  white  pubescence;  pygidium  coarsely  punctate,  feebly  cari- 
nate; claws  broadly  toothed  at  middle.  Length  .25  inch. ; 6.5  mm. 

Male. — Prostenium  coarsely  punctured,  s[)arsely  pubescent ; first 
two  ventral  segments  roughly  sculptured  at  middle;  anterior  tibia 
distinctly,  middle  tibia  feebly  mucronate,  the  posterior  simple. 

Female. — Prosternum  less  closely  punctate,  scarcely  hairy  ; first 
two  veutral  segments  simply  punctate ; tibite  all  simple. 

Variaiiom. — The  three  specimens  before  me  seem  to  have  been 
collected  with  care  and  have  a rather  dense  efflorescence  between  the 
hairs,  so  that  they  seem  very  conspicuous.  It  is  |)robable  that  speci- 
mens collected  in  alcohol  or  wet  in  any  way,  lose  the  efflorescence, 
and  the  pubescent  spots  will  appear  le.ss  distinct.  There  is  no  varia- 
tion in  the  specimens  examined.

little  dilated  bebind  the  middle,  apices  rounded,  serrulate,  disc  very  slightly  de- 
pressed, basal  fovese  feeble,  surface  imbricately  sculptured  and  with  three  faint 
l)ubescent  s])ots  on  each  side,  one  at  base,  second  in  front  of  middle,  the  last  one- 
third  from  a))ex ; body  beneath  rather  more  shining  than  above;  prosternal  lobe 
truncate  and  broadly  emarginate,  intercoxal  process  very  little  narrowed  to  apex, 
the  tip  truncate,  propleurae  punctate  and  subreticulate  ; metasternum  at  sides 
strigose,  somewhat  reticulate,  pubescent  at  its  posterior  angle,  as  is  also  the  outer

segment  pubescent ; pygidium  indistinctly  punctate,  carinate  along  the  median 
line  ; claws  broadly  toothed.  Length  .24  inch. ; 6 mm. 

The  male  differs  from  the  female  in  having  the  prosterniim  slightly 
more  densely  punctate  and  the  first  two  ventral  segments  more  ru- 
go.se  at  middle.  Five  specimens  have  been  examined,  four  of  which 
are  in  the  National  Museum. 

This  species  is  not  conspicuously  marked,  but  among  those  in  which 
the  antenntc  are  serrate  from  the  fifth  joint  it  may  be  known  by  the 
very  convex  thorax,  with  feeble  median  depression,  the  absence  of 
angular  carina  and  the  feeble  j)ube.scent  spots  of  the  elytra. 

Hah. — Texas,  precise  locality  unknown. 

.4.  silboiiictiiM  Gory. — Form  relatively  robust,  piceous  with  faint  bronze 
lustre,  more  evident  on  the  thorax,  elytra  ornate  with  pubescent  spaces.  Antennge 
scarcely  reaching  the  middle  of  the  thorax,  piceous,  slightly  bronzed,  strongly 
serrate  from  the  fifth  joint;  head  convex,  with  a median  depression  from  the 
occiput  to  the  clypeus,  surface  relatively  coarsely  strigose.  Thorax  wider  than 
long,  sides  regularly  arcuate,  margin  sinuate,  hind  angles  rectangular,  without 
trace  of  carina,  disc  convex,  with  a rather  broad  but  not  deep  median  depression 
extending  from  base  to  apex,  lateral  depression  well  marked,  extending  toward 
the  base,  surface  transversely  strigose  at  middle,  obliquely  at  sides,  punctate  near 
the  margin;  scutellum  transversely  carinate;  elytra  slightly  sinuate  behind  the 
humeri,  dilated  somewhat  behind  the  middle,  apices  rounded,  serrulate,  disc 
slightly  flattened  with  a vague  costa,  sutural  margin  elevated,  except  at  basal 
fourth,  surface  coarsely  imbi-icate,  somewhat  strigose  at  middle,  smoother  near 
apex,  a pubescent  space  extending  from  the  humeri  to  the  middle,  with  two  in- 
terruptions, then  turning  obliquely  outwards,  a second  oblique  baud  one  fourth 
from  apex;  body  beneath  more  shining  than  above;  prosternal  lobe  broadly 
emarginate.  intercoxal  process  gradually  narrowed,  acute  at  apex,  propleurte 
sparsely  punctate;  metasternum  transversely  strigose,  somewhat  reticulate. 
Abdomen  very  sparsely,  indistinctly  punctate  over  its  entire  surface,  vertical 
portion  of  segments  not  conspicuously  pubescent;  pygidium  sparsely  punctate, 
not  distinctly  carinate;  claws  broadly  tootbed  at  middle.  Lengtb  .16 — .18  inch.; 
4—4.5  mm. 

Sexual  characters. — In  the  specimens  before  me  1 am  unable  to

find  any  well  marked  secondary  sexual  characters.  One  specimen, 
seemingly  a male,  has  the  prosternum  somewhat  more  opaque  and  a 
little  more  pubescent. 

Varmtiom. — The  usual  variations  dependent  on  abrasion  must  be 
expected  here  as  elsewhere.  While  the  vast  majority  of  specimens 
have  the  antennce  serrate  beginning  with  the  fifth  joint,  one  in  my 
cabinet  begins  at  the  fourth,  that  is,  the  fourth  joint  more  nearly 
resembles  the  fifth  than  the  third.  Such  cases  as  this  must  be  classed 
as  abnormalities,  and  are  very  confusing  to  a systematist,  or  to  one 
attempting  to  determine  sjiecific  names  with  but  little  material. 

Hab. — Canada  to  North  Carolina,  westward  to  Illinois.  It  is  not 
recorded  from  the  New  England  States,  but  probably  occurs  there. 


A.  piitilliiM  Say.  — Form  nearly  of  subcinctus  ; dark  olivaceous  bronze,  mod- 
erately shining.  Antennae  scarcely  attaining  the  middle  of  the  thorax,  piceous, 
serrate  from  the  fifth  joint;  head  convex,  with  a feeble  occipital  impression, 
front  s])arsely  indistinctly  punctate,  slightly  alntaceous.  Thorax  one-third  wider 
than  long,  sides  regularly  arcuate,  margin  sinuous,  hind  angles  rectangular 
without  trace  of  carina;  disc  convex,  with  a feeble  linear  median  impression, 
lateral  depressions  deep  along  the  side,  surface  transversely  strigose,  but  more 
evidently  punctate  near  the  apex;  scutellum  transversely  carinate  ; elytra  ex- 
tremely little  sinuate  at  middle,  apices  rounded,  serrulate ; disc  slightly  depressed 
at  middle,  a feeble  basal  fovea,  on  each  side  a suhcostiform  elevation,  between 
which  and  the  suture  on  each  side  the  elytra  are  vaguely  channeled,  surface 
imbricate,  hut  not  closely;  body  beneath  usually  darker,  hut  more  shining  than 
above;  prosterual  lobe  subtruncate,  sometimes  feebly  emarginate,  intercoxal 
process  relatively  broad,  obtuse  at  apex  ; propleurae  comparatively  smooth  ; 
metasternum  at  sides  rather  finely  punctate  and  substrigose.  Abdomen  sparsely 
punctate  over  the  entire  surface  and  faintly  alntaceous ; pygidium  very  indis- 
tinctly punctate,  not  at  all  carinate;  claws  broadly  toothed  at  middle.  Length 
.12  inch. ; 3 mm. 

Male. — Front  greenish,  more  opaque  and  more  closely  sculptuTed. 
Prosternum  more  closely  punctate  along  the  middle  and  slightly  pu- 
bescent. Abdomen  simple,  not  roughened  at  base. 

Female. — Front  aeneous,  more  shining  and  more  sparsely  punctate. 
Prostern u in  not  pubescent. 

Variations. — The  color  is  very  constant.  The  discal  cosUr  of  the 
elytra  vary  considerably  in  their  distinctness,  and  are  sometimes 
nearly  absent.  In  the  outline  of  the  upper  surface,  when  viewed 
laterally,  some  are  nearly  straight,  others  quite  arched. 

This  species  is  the  smallest  found  in  the  Atlantic  region  proper, 
and  is  remarkable  in  having  the  lower  angle  of  the  eve  acute. 

Hab. — Canada  (Pettit),  Illinois,  Indiana  (Say).

dark  brassy  bronze,  moderately  shining.  Antennse  piceotis,  faintly  bronzed, 
iittaining  the  middle  of  the  thorax,  serrate  from  the  fifth  joint;  head  convex,

eeut ; tirst  ventral  segment  with  a short,  smooth,  median  groove  at 
its  posterior  edge. 

Female. — Prosternum  sparsely  jtunctate  ; ventral  segments  simple. 

Variations. — None  have  been  observed  in  the  many  specimens 
seen . 

This  species,  like  ventralis  of  the  preceding  series,  resembles 
Taphroceras  a.griloides,  and  in  the  present  rather  more  so  than  in  that 
from  the  fact  that  there  is  here  no  pubescent  elytral  vitta. 

When  the  thorax  is  viewed  fi'om  above  and  from  behind,  the 
scul|)ture  has  a reticulate  appearance,  but  when  seen  from  in  front 
is  very  obliquely  and  not  closely  strigo.se.

densely  punctured  and  pubescent.  Metasternum  concave,  densely 
punctured  aud  pubescent;  anterior  tibiae  distinctly  mucronate,  mid- 
dle and  posterior  simple  ; first  ventral  segment  slightly  fiattened  at 
middle. 

Female. — Front  less  impressed ; in  this  sex  the  transverse  depression 
is  more  often  seen.  Prosternum  rather  sparsely  punctate,  not  hairy. 
INIetasternum  flat,  not  closely  punctate,  nor  hairy  ; ventral  segments 
simple;  tibiae  mucronate. 

Variations. — The  color  is  but  little  variable,  but  the  pubescence 
may  be  more  or  less  abraded.  The  median  dorsal  depression  of  the 
thorax  may  be  more  or  less  dee[),  but  still  preserving  the  form  of 
two  foveae  united  by  a groove.

'File  three  specimens  of  tliis  species  examined  were  all  females,  .so 
that  I am  unable  to  state  the  sexual  differences.  They  show  no 
variation. 

This  species  resembles  Lecontel  (subfasciatus)  so  closely,  that  I 
found  it  mixed  with  that  s[)ecies  in  my  own  and  another  cabinet. 
The  form  of  the  prosternal  lobe  will,  however,  separate  them  at  once. 
Suiierficially,  the  sculpture  of  the  middle  of  the  thorax  will  distin- 
guish them.  In  this  species  there  is  a straight  depression,  Avhile  in 
Lecontel  there  are  two  depressions,  anterior  and  posterior  united  by 
a narrower  depressed  space.

slightly  broader  behind  the  middle  then  obliquely  narrowed  to  apex,  a])ices  ob- 
liquely rounded,  serrulate ; disc  slightly  depressed,  basal  fovea*  feeble,  on  each 
side  three  pubescent  spots,  as  in  fallax;  body  beneath  as  abf>ve : prosternal  lobe 
obtusely  rounded,  iutercoxal  ju-ocess  relatively  broad,  truncate  at  tip,  propleurse

carinate;  claw's  broadly  toothed.  Length  .12 — .18  inch.;  3 — 4.5  mm. 

Male. — Head  very  densely  punctate,  cupreous.  Prosternum 
sparsely  pubescent;  first  two  ventral  segments  impressed  at  middle, 
more  deejily  on  the  first. 

Female. — Front  less  punctate,  teneous.  Prosternum  scarcely  pu- 
bescent ; ventral  segments  simple. 

The  numerous  specimens  examined  are  constant  in  appearance, 
varying  only  in  size. 

There  are  but  few  species  so  obliquely  strigose  ou  the  thorax  as 
this  one,  the  strigosity  beginning  at  the  middle  and  running  diago- 
nally forward,  Tho.se  so  sculptured  are  I'eadily  known  by  their 
structural  characters. 

Hab. — Western  Texas  and  southern  Arizona  (Morrison). 

•A.  Felix  n.  sp. — Form  moderately  robust,  suhcyliudrical,  slightly  depressed,

pubescence.  Antennae  short,  scarcely  reaching  the  middle  of  the  thorax,  piceous, 
strongly  serrate  from  the  fifth  joint;  head  feel)ly  convex,  a vague  median  im- 
pression more  evident  in  the  female,  surface  rather  roughly  punctate-strigose. 
Thorax  as  long  as  wide  (male),  or  a little  wider  than  long  (female),  sides  nearly 
straight  'J, , or  slightly  arcuate  9,  hind  angles  rectangular,  with  a fine  straight 
Carina,  more  evident  in  the  J,  margin  sinuous;  disc  regularly  convex,  without 
median  or  lateral  depressions,  surface  rather  coarsely  transversely  strigose,  with 
a pubescent  space  at  sides,  broadest  behind,  enclosing  the  carina;  scutellum 
transversely  carinate  ; elytra  scarcely  sinuate  behind  the  humeri,  apices  rounded, 
more  acute  and  more  distinctly  serrulate  in  % ; disc  with  a very  vague  costa, 
between  which  and  the  suture,  in  a slight  channel,  is  the  pubescent  vitta;  sur- 
face moderately  closely  imbricate;  body  beneath  geueous,  with  fine  short  pubes- 
cence; prosternal  lobe  obtusely  rounded,  the  iutercoxal  process  rather  broad, 
truncate  at  tip,  propleurse  punctate  and  pubescent;  metasternum  at  sides  closely 
punctate  and  somewhat  strigose.  Abdomen  moderately  closely  finely  punctate, 
denser  at  sides  of  first  segment;  pygidium  sparsely  punctate,  not  carinate  ; claws 
dissimilar  in  the  sexes.  Length  .22 — .24  inch. ; 5.5 — 6 mm. 

Male. — Front  flatter,  tlie  median  imprecision  feeble.  Thorax  as 
long  as  wide,  tlie  sides  nearly  straight.  Prosternuin  roughly  punc- 
tate, sparsely  pubescent.  Abdomen  simple,  the  first  segment  rather 
rough  at  middle  ; claws  on  all  the  feet  cleft  very  near  the  apex, 
almost  bifid  ; tibite  simple. 

Female. — Head  more  convex,  the  median  impression  deeper.  Tho- 
rax a little  wider  than  long,  the  sides  moderately  arcuate.  Proster- 
num less  rugose,  scarcely  pubescent.  Abdomen  le.ss  rugose  ; claws 
broadly  toothed. 

Variation. — In  this  species,  as  in  others  already  noted,  there  is  be- 
tween the  pubescence  a whitish  efflorescence,  which  makes  the  pu- 
bescence seem  denser  and  whiter,  but  when  this  is  removed  by  acci- 
dental moistening  the  reverse  is  produced. 

This  species  resembles  jacobinm,  of  the  preceding  series,  in  form 
and  color,  but  differs  in  the  form  of  the  antennm  and  the  presence 
of  the  pubescent  vitta.  It  resembles  still  mure  blandus  but  that 
has  no  trace,  whatever,  of  carina  in  the  hind  angles,  and  the  proster- 
nal lobe  is  more  distinctly  emarginate. 

Hab. — Arizona,  probably  near  Tucson. 

A.  iiii|>exii!it  u.  sp. — Subcylindrical,  slightly  flattened  above,  dull  cupreo- 
seneous,  each  elytron  with  three  indistinct  pubescent  spots.  Antennae  not  reach- 
ing the  middle  of  the  thorax,  piceous,  with  slight  aeneous  lustre,  serrate  from 
the  fifth  joint;  head  broadly,  but  feebly  coucave,  with  a median  impressed  line, 
surface  closely  punctate-strigose.  Thorax  scarcely  wider  than  long,  the  sides 
very  feebly  arcuate,  slightly  sinuate  near  the  hind  angles,  which  are  rectangular 
and  distinctly  carinate,  margin  sinuous;  disc  convex,  with  a median  depression 
variable  in  distinctness,  and  when  well  marked  with  an  impressed  line  at  bottom

extending  from  base  ne-irly  to  apc.x,  lateral  oblique  depre.ssiotis  moderately  well 
marked,  surface  closely  transversely  stri};ose,  becoming  oblique  and  longitudinal 
toward  the  sides  : scuteliiim  transversely  carinate  ; elytra  feebly  sinuate  behind 
the  humeri,  the  apices  rounded,  serrulate;  disc  slightly  flattened,  but  not  snlcate, 
basal  depressions  feeble,  surface  closely  granulate-imbricate,  somewhat  strigose 
at  sides  in  front,  each  elytron  with  three  faint  pubescent  spots,  one  at  base,  one 
in  front  of  middle,  the  posterior  one-third  from  apex;  body  beneath  more  shin- 
ing than  above  ; prosternal  lobe  obtusely  rounded,  iiitercoxal  process  rather  wide, 
parallel,  trinicate  at  apex,  propleurie  closely  strigose  punctate;  metasternum  at 
sides  coarsely  transversely  strigose.  Abdomen  moderately  closely  punctate, 
more  or  less  strigose  over  the  whole  surface,  but  more  coarsely  at  the  sides  of  the 
first  two  segments;  jiygidium  indistinctly  punctate,  feebly  carinate;  claws 
broadly  toothed.  Length  .27 — .29  inch. ; 7 — 7.5  mm. 

Male. — Front  more  closely  punctate,  but  rather  less  concave. 
'riiora.N  with  a feebler  median  impression  without  impressed  line. 
Prosternum  densely  punctured,  sparsely  pubescent,  the  pubescence 
extending  on  the  metasternum,  which  is  flattened  and  closely  punc- 
tate ; first  two  ventral  segments  vaguely  sulcate  their  entire  length 
and  pubescent  in  the  depression  ; tibiie  simple. 

Female. — Head  less  closely  punctate,  the  concavity  a little  more 
jironounced  ; median  depression  of  thorax  well  marked  with  a fine 
impressed  line  at  bottom.  Prosternum  less  densely  punctate,  scarcely 
pubescent.  Metasternum  slightly  convex  ; ventral  segments  not 
impressed. 

Variations.  — In  the  two  specimens  before  me  the  variations  have 
been  alluded  to,  and  seem  to  be  sexual. 

'fhe  pubescent  spots  of  the  elytra  are  not  distinct  in  either  speci- 
men, except  at  base  of  elytra,  but  are  very  plainly  indicated  by  the 
denser  and  finer  punctuation.  Closely  resembles  Jinridanus,  but  in 
the  latter  the  ])ygidium  is  not  carinate,  and  there  is  scarcely  a trace 
of  median  impression  of  the  thorax.

head  slightly  concave  with  a fine  median  impressed  line,  surface  closely  punctate- 
strigose.  Thorax  one-fourth  wdder  than  long,  slightly  narrowed  at  base,  sides 
feebly  arcuate,  slightly  sinuate  near  the  posterior  angles,  which  are  rectangular, 
and  with  an  obtuse,  straight  carina,  margin  sinuous;  disc  convex,  a flattening 
or  slight  depression  in  front  of  the  .scutellum,  lateral  oblique  impressions  well 
marked,  surface  transversely  punctate-strigose,  but  not  roughly  ; scutellum  trans- 
versely carinate;  elytra  scarcely  sinuate  at  the  sides,  the  apices  rounded  and

nal  lobe  truncate  and  vaguely  einarginate,  intercoxal  process  rather  broad,  trun- 
cate at  apex,  propleurse  coarsely  punctate,  sparsely  pubescent;  metasternum  at 
sides  rather  roughly  strigose  and  punctate.  Abdomen  moderately  closely  punc- 
tate, strigose  at  sides  of  first  two  segments;  pygidium  sparsely  punctate,  with  a 
smooth  median  line;  claws  cleft,  forming  a broad  tooth.  Length  .28  inch. ; 7 mm. 

Male. — Prosternum  densely  punctured,  pubescent;  first  two  ven- 
tral segments  very  feebly  impressed  along  the  middle,  scarcely  pu- 
bescent ; tibite  not  mucronate. 

Female. — Prosternum  less  roughly  punctate,  not  pubescent ; ven- 
tral segments  not  impressed. 

The  two  specimens  before  me  do  not  vary.  The  types  are  before 
me  and  show  that  while  the  species  is  fairly,  but  too  briefly  described 
by  Crotch,  its  position  in  his  analytical  table  is  erroneous.  He  men- 
tions pubescent  patches  at  the  sides  of  the  last  three  ventral  segments, 
but  this  is  merely  the  result  of  a slightly  denser  punctuation. 

Hah. — Northern  Florida,  probably  near  Jacksonville. 

A.  addeiidiis  Crotch. — Moderately  robust,  dull  cupreo-aeneous,  subopaque, 
elytra  with  three  pubescent  spots  on  each  side,  sometimes  absent  or  very  faint. 
Antennae  piceous,  serrate  from  the  fifth  joint,  reaching  the  middle  of  the  thorax  ; 
head,  from  above,  concave,  a moderately  deej)  impression  from  the  occiput  to  the

very  little  wider  than  long,  slightly  narrowed  posteriorly,  sides  feebly  arcuate, 
slightly  sinuate  in  front  of  hind  angles,  which  are  rectangular  and  with  a 
straight,  well  defined  carina;  disc  convex,  with  at  most  a feeble  median  impres- 
sion, which  may  he  entirely  absent,  lateral  oblique  impression  moderate,  surface 
closely  transversely  strigose;  scutellum  transversely  carinate;  elytra  feebly 
sinuate  at  sides  and  but  little  broadened,  apices  rounded,  feebly  serrulate ; disc 
slightly  flattened,  a vague  channel  each  side  of  suture,  basal  fovese  feeble,  surface 
moderately  closely,  but  not  roughly  imbricate,  the  pubescent  spots,  when  present, 
as  in  fall  ax ; body  beneath  more  shining  than  above;  prosternal  lobe  obtusely 
rounded,  with  a vague  sinuatiou  at  middle,  intercoxal  process  parallel,  squarely 
truncate  at  apex,  propleurfe  shining,  indistinctly  reticulate;  metasternum  at 
sides  roughly  punctate-strigose  and  with  the  episternum  and  outer  side  of  coxal

along  the  median  line. 

Female. — Front  often  with  a crescentic,  transverse  impression  in 
addition  to  the  median.  Metasternum  convex,  sparsely  jiunctate; 
ventral  segments  not  impres.sed.

Yarlatiom. — Two  forms  may  l)e  separated  in  this  species,  those 
witli  tlie  i)ubescent  spots  well  marked  and  those  without  them.  The 
former  variety  shows  some  pubescence  at  the  sides  of  the  thorax  and 
at  the  sides  of  the  last  three  ventral  segments.  Those  without  spots 
show  in  nearly  all  the  specimens  the  spaces  with  denser  fine  punc- 
tuation, but  even  this  may  be  absent.  In  the  typical  specimens,  as 
Crotch  states,  there  is  a tendency  to  form  a basal  and  subapical  spots. 
Between  the  specimens  with  no  spots  and  the  others  I have  every 
necessary  link  in  my  cabinet. 

The  median  thoracic  imjn'ession  is,  at  best,  faint,  but  in  some  speci- 
mens entirely  wanting,  in  others  represented  by  a slight  antescutellar 
depression.

.4,  laciistris  Lee. — Moderately  elongate,  nearly  parallel,  slightly  depressed 
above,  color  variable,  dark  bronze,  green  or  bine.  Antennfe  piceous.  not  reaching 
the  middle  of  the  thorax,  serrate  from  the  fifth  joint:  head  convex,  a feeble 
median  furrow  from  the  occiput  to  the  middle  of  the  front,  surface  roughly 
puuctate-strigose.  Thorax  scarcely  wider  than  long,  the  sides  feebly  arcuate, 
slightly  sinuate  near  the  hind  angles,  these  rectangular  with  a short  fine  carina, 
margin  straight,  deflexed  in  front  only;  disc  convex,  sometimes  with  a vague 
median  impression,  the  lateral  depressions  absent,  surface  transversely  and 
rather  closely  strigose,  with  fine  punctures;  scutellum  variable,  either  carinate 
or  not;  elytra  feebly  sinuate  at  sides  and  but  little  dilated  behind  the  middle, 
apices  rounded,  serrulate;  disc  slightly  flattened,  basal  fovea  feeble,  surface 
closely  and  rather  roughly  imbricate;  body  beneath  more  or  less  blue;  proster- 
nal  lobe  broadly  rounded,  intercoxal  process  rather  broad,  truncate  at  apex,  pro- 
pleurse  strigo.se  and  punctate,  sparsely  pube.scent ; metasternum  at  sides  trans- 
versely strigose,  not  roughly  nor  closely.  Abdomen  transversely  strigose,  not 
roughly  nor  closely;  pygidium  sparsely  punctate,  not  carinate;  claws  broadly 
toothed.  Length  .16 — .30  inch.;  4— 7.5  mm. 

Male. — Front  scmiewhat  more  opaque.  Prosternum  densely  punc- 
tured and  hairy.  Metasternum  concave  ami  hairy;  first  two  ventral 
segments  rather  deejtly  impressed  their  whole  length,  the  impression 
hairy;  tibite  simple. 

Female. — Prosternum  coarsely  sculptured,  transversely  strigose, 
but  not  hairy.  Metasternum  slightly  convex,  transversely  roughly 
strigose,  not  hairy  ; ventral  segments  not  imjiressed. 

Vaviatmu. — The  color  varieties  have  already  been  recorded.  The 
blue  forms  are,  however,  very  rare.  The  scutellum  may  be  trans- 
versely carinate  or  not,  sometimes  the  carina  is  interi-upted  in  the 
middle.  Fully  developed  specimens  usually  have  the  carina  very 
distinct;  in  the  small  and  feeble  forms  it  is  wanting.  The  same  is 
true  of  the  feeble  median  depression  of  the  thorax.

This  species  was  originally  named  from  some  small  and  feeble  forms 
from  the  North,  which,  at  first  sight,  are  very  unlike  the  larger  forms 
from  the  Texan  region.  It  is  also  evident  that  LeConte  had  speci- 
mens of  another  species  along  with  his  types  as  tlie  so-called  male  is 
really  that  of  defedus.  At  present  the  specimen  is  not  found  with 
tlie  types,  having  |)robably  been  removed  either  by  himself  or  Crotch. 

The  larger  Texan  forms  were  described  l)y  LeConte  as  cuneus  from 
a single  specimen  in  Ulke’s  cabinet.  From  not  finding  a type  in  the 
LeConte  cabinet.  Crotch  subsequently  named  the  specimens  in  my 
cabinet  pubiventris.

greenish.  Antennie  rather  slender,  reaching  the  middle  of  the  thorax,  joints 
longer  than  wide,  the  third  obviously  shorter  than  the  fourth,  piceous.  slightly 
bronzed,  serrate  from  the  fifth  Joint:  front  Hat.  a very  feeble  median  impression, 
densely  punctate,  occiput  strigose.  Thora.x  wider  than  long,  sides  not  strongly 
arcuate,  hind  angles  rectangular,  with  a well  defined,  slightly  oblique  carina, 
margin  nearly  straight,  deHexed  in  front;  disc  convex,  without  median  depres- 
sion, lateral  oblique  depressions  well  marked,  surface  transversely  strigose  with 
fine  punctures  between;  scutellum  transversely  carinate ; elytra  feebly  sinuate 
at  sides,  slightly  broader  behind  the  middle,  apices  rounded,  serrulate,  basal 
fovefe  moderate,  disc  slightly  depressed,  surface  imbricate;  body  beneath  rather 
more  shining  than  above;  prosternal  lobe  truncate,  more  or  less  emarginate,  the 
intercoxal  process  narrowed  at  apex,  propleur®  sparsely  punctate;  metasternum 
at  sides  asperately  punctate.  Abdomen  very  sparsely  punctate  ; pygidium  sparsely 
punctate,  not  carinate  ; claws  broadly  toothed.  Length  .14 — .20  inch. ; 3.5 — 5 mm. 

Male. — Front  more  densely  punctate,  more  opaque,  bluish  green. 
Prosternum  densely  punctured,  hairy,  the  hair  extending  somewhat 
on  the  metasternum  ; first  two  ventral  segments  flat  or  feebly  ini- 
pressed  at  middle,  slightly  pubescent. 

Female. — Front  slightly  more  convex,  the  punctures  coarser  and 
less  clo.se,  more  shining,  teneous.  Prosternum  not  hairy  ; ventral 
segments  not  impressed. 

Farndm/i,s.— Notwithstanding  the  wide  area  over  which  this  spe- 
cies is  distributed,  there  seems  to  be  no  variation,  except  slightly 
in  color  and  size.  Some  of  the  narrower  forms  with  a slight  greenish 
color  resemble  offo.sqt.s  considerably,  but  the  structure  of  both  antenuDe 
and  claws  will  separate  them.  On  the  other  hand,  some  of  the  forms 
oi  fallax  deprived  of  pubescence  are  apt  to  be  mixed  with  the  present 
species,  and  are  not  easy  to  separate  without  great  care,  but  the  form 
of  the  antenme  and  the  flat  base  of  clypeus  in  the  present  sj)ecies 
will  render  them  separable.

Of  the  habits  of  this  species  nothing  is  known.

Anteuufe  pa.ssing  the  middle  of  the  thorax,  aeneous,  serrate  from  the  fifth  joint, 
the  serrate  joints  wider  than  long;  head  convex,  with  a faint  median  furrow, 
surface  very  coarsely  punctate,  the  occiput  strigose.  Thorax  wider  than  long, 
slightly  narrowed  at  base,  sides  feebly  arcuate  in  front,  oblique,  with  a slight 
sinuation  posteriorly,  lateral  margin  straight,  defiexed  in  front,  hind  angles 
rectangular,  with  a moderately  long,  but  not  strongly  elevated  carina ; disc  con- 
vex, without  trace  of  a median  impression,  lateral  oblique  impressions  feeble, 
surface  rather  coarsely  transversely  strigose  with  luinctures  in  the  furrows; 
scutellum  usually  carinate,  sometimes  not;  elytra  faintly  sinuate  at  the  sides 
and  scarcely  dilated  behind  the  middle,  the  apices  rounded  and  serrulate,  disc 
slightly  depressed,  the  basal  fovese  feeble,  surface  rather  coarsely  imbricate;  body 
beneath  colored  as  above;  prosternal  lobe  broadly  rounded,  the  intercoxal  pro- 
cess rather  wide  and  truncate  at  apex,  propleurse  punctate,  but  not  roughly  nor 
closely;  metasternum  at  sides  coarsely  transversely  strigose.  Abdomen  feebly 
transversely  strigose,  more  roughly  at  the  sides  of  the  first  two  segments;  py- 
gidium  sparsely  punctate,  the  median  line  smooth,  not  carinate;  claws  broadly 
toothed  at  middle.  Length  .18 — .22  inch.;  4.5 — 5.5  mm. 

Male. — Front  rather  less  convex,  with  more  distinct  median  im- 
pression and  more  coarsely  punctate.  Prosternum  roughly  and 
ckxsely  punctate,  hairy.  Metasternum  closely  punctate  and  slightly 
hairy  ; first  two  ventral  segments  flattened  at  middle,  closely  punc- 
tate and  with  short  hairs. 

Female. — Head  more  convex  and  more  evidently  strigose.  Pro- 
sterjuun  and  metasternum  transversely  strigose,  not  {)ubescent ; first

The  numerous  specimens  examined  show  no  variation,  except  a 
little  in  size  in  specimens  from  the  most  remote  localities. 

The  species  resembles  egenus  somewhat,  but  is  more  robust,  has 
shorter  antenme  and  an  entire  prosternal  lobe.  Specimens  of  lacus- 
tris  have  been  seen  which  somewhat  resemble  this  one,  but  the  male 
characters  will  then  readily  separate  them.

characters. 

Hub  — Western  Nevada  (Morrison). 

.4.  piisilliis  Say. — Form  of  aclimiuutive  rujicollis ; head  and  thorax  usually 
seueous  or  cupreous,  elytra  purple-hlack  (but  variable),  moderately  shining.  Au- 
teunse  reaching  the  middle  of  the  thorax,  piceous,  serrate  from  the  fifth  joint, 
serrate  joints  wider  than  long;  head  convex,  a feeble  median  impression  from 
the  occiput  to  the  base  of  the  clypeus,  surface  moderately  closely  coarsely  punc- 
tate. Thorax  wider  than  long,  slightly  narrowed  at  base,  sides  arcuate  in  front, 
slightly  sinuate  near  the  hind  angles,  which  are  rectangular  and  distinctly  cari- 
nate. margin  nearly  straight,  deflexed  in  front,  disc  convex,  a broad  transverse 
depression  in  front  of  base,  so  that,  when  viewed  laterally,  the  median  line  of 
the  thorax  is  more  convex  in  the  anterior  half,  lateral  oblique  depression  mod- 
erately deep,  surface  moderately  coarsely  transversely  strigose,  with  coarse  punc- 
tures in  the  grooves;  scutellum  carinate  or  not;  elytra  sinuate  at  the  sides, 
distinctly  dilated  behind  the  middle,  apices  rounded,  serrulate ; disc  flattened, 
usually  a vague  costa  on  each  side,  a feeble  concavity  each  side  of  the  suture, 
basal  depressions  feeble,  surface  with  imbricate  sculpture,  not  rough  nor  close; 
body  beneath  piceou.s,  shining,  faintly  bronzed;  prosternal  lobe  truncate  and 
broadly  emargiuate,  the  intercoxal  process  acutely  oval  at  tip,  propleurse  punc- 
tate and  strigose;  metasternum  at  sides  strigose  and  subreticulate.  Abdomen 
sparsely  finely  punctate,  a little  more  coarsely  at  the  side  of  the  first  segment; 
pygidium  sparsely  punctate,  not  carinate  ; claws  broadly  toothed.  Length  .12 — 
.16  inch. ; 3 4 mm. 

Male. — Front  flatter  and  more  opaque;  flrst  ventral  slightly  flat- 
tened at  middle  and  rugose. 

F emale. — Front  more  shining  and  rather  more  convex  ; first  ventral 
convex  and  not  roughened. 

Variations. — The  general  aspect  of  this  species  is  that  of  a diminu- 
tive rujicollis  with  the  thorax  less  conspicuously  cupreous.  The  tho- 
rax is  often  brassy  with  purplish  spaces  at  the  sides.  Sometimes  the 
elytra  are  seneous.  These  last  forms  resemble  jjutillus,  but  these 
have  no  carina  in  the  hind  angles  of  the  thorax,  and  the  disc  has  a 
distinct  median  impression.

This  species  was  placed  by  LeConte  in  the  group  with  the  incurved 
tootli  of  the  claws,  but  the  claws  and  an  ten  life  are  both  different  from 
that  series. 

The  name  parvus  has  been  suggested  for  this  species  by  Saunders 
in  “ Catalogus  Bnprestidarum,”  but  there  seems  to  be  no  valid  reason 
for  the  the  change.  It  is  certainly  ])ermissible  to  use  jnisUhis  and 
putillus  in  the  same  genus.

On  a collection  of  Hyinenoptera  made  in  Jamaica 
during  April,  1891. 

BY  WILLIAM  J.  FOX. 

The  collection  on  which  this  article  is  based  was  made  in  Jamaica, 
during  April  of  the  present  year,  by  myself  and  Mr.  Charles  W. 
Johnson,  of  the  Wagner  Free  Institute  of  Science,  Philadelphia. 

About  seventy  species  are  giyen  herein,  which  will  be  increased  to 
nearly  one  hundred  when  the  Formicidie  and  a number  of  species 
of  Andrenidie  have  been  classified.

PAPER  II* 

BY  C.  H.  TYLER  TOWNSEND. 

The  study  of  the  Tachinidse  has  progressed  considerably  of  late 
in  the  line  of  descriptive  work.  Up  to  within  a few  years  a large 
number  of  forms,  necessitating  the  foundation  of  new  genera,  had 
remained  unnoticed.  iNIr.  van  der  Wulp  has  given  us  descriptions 
of  a considerable  number  of  these,  which,  however,  are  mainly  con- 
fined to  Old  Mexico.  Messrs.  Brauer  and  von  Bergenstamm  have 
erected  a great  number  of  genera  from  all  parts  of  the  w’orld,  some 
of  which  can  be  em})loyed  ; but  many  are  unfortunately  either  based 
on  invalid  characters,  or  insufficiently  de.scribed  and  without  figures 
to  enable  their  recognition.  A few  other  authors  have  contributed 
isolated  descriptions  of  genera  in  this  grou]).  Notwithstanding  these 
recent  additions  I believe  it  necessary  at  this  time  to  erect  a number 
of  new  genera  for  the  reception  of  forms  herein  described,  which 
cannot  be  reconciled  with  any  of  the  published  descrii»tions  or  figures 
of  previous  genera. 

The  present  jiaper  is  the  result  of  a study  of  a considerable  col- 
lection of  material,  all  from  within  the  limits  of  the  United  States ; 
and  will,  the  writer  hopes,  contribute  toward  a more  accurate  know- 
ledge of  our  many  species  among  these  useful  parasitic  Hies. 

SIPHOPLAGIAf  11.  gen. 

Belongs  in  the  sub-group  with  Plagia,  from  which  it  differs  prin- 
cipally by  the  elongate,  slender  proboscis,  and  absence  of  bristles  on 
the  sides  of  face.  Head,  thorax  and  abdomen  of  nearly  equal  width 
in  the  9 ( ? abdomen  narrower  in  S ).  Eyes  bare  ; front  wide,

retracted,  oral  margin  prominent,  facial  ridges  bare ; vibrissse  decus- 
sate, inserted  near  the  oral  margin  ; cheeks  broad,  one-half  the 
liight  of  eyes  in  9 ( ? narrower  in  S ),  bare,  with  a fringe  of  bris- 
tles on  the  lower  and  front  border,  extending  but  slightly  above  the 
vibrissie.  Anteniue  little  more  than  two-thirds  the  length  of  the 
face  ; first  joint  short,  second  somewhat  elongate,  third  almost  twice 
the  length  of  the  second,  not  widened,  rounded  at  the  end ; arista

short  jiubescent,  distinctly  o-jointed,  the  second  joint  elongate.  Pro- 
lioscis  elongate,  about  twice  as  long  as  hight  of  head,  geniculate, 
licnt  forward,  slender  and  corneous,  labella  very  slightly  developed  ; 
palpi  well  developed,  cylindrical,  slightly  thickened  at  tip.  Scutellum

small  costal  spine  ; apical  cell  ending  on  the  front  border  of  the  wing 
very  much  before  the  apex,  narrowly  open  or  almost  closed  in  the 
margin  ; hind  cross-vein  very  oblique,  arising  ojiposite  or  a little 
behind  the  small  cross-vein,  approximating  the  bend  of  the  fourth 
longitudinal ; apical  cross-vein  also  oblique,  both  nearly  parallel  with 
the  hind  border  of  wing;  fourth  vein  with  a very  long  stump  at  its 
angle;  third  vein  spined  on  the  proximal  two-thirds  of  its  extent. 
Type,  S',  anomala  n.  sp. 

This  genus  diflers  from  Plagia,  as  above  stated,  by  the  structure 
of  the  proboscis,  and  the  absence  of  rows  of  bristles  on  the  sides  of 
the  face ; also  by  the  macrochsetie  being  only  marginal.  It  agrees 
with  it  in  all  other  essential  characteristics.

width  of  the  front,  widening  behind  where  it  sj)lits  on  each  side  of  the  ocellar 
area;  four  pairs  of  ocellar  bristles,  a rather  weak  pair  at  the  vertex  directed 
outward  and  backward,  but  inclined  forward  at  the  point,  a weaker  pair  Just  in 
front  of  these  directed  forward  and  a little  outward,  a strong  pair  farther  in 
front  directed  widely  outward  and  but  very  slightly  forward,  and  a weak  pair

genus  has  priority,  as  it  was  described  in  1888  (Biol.  C.-A.  Di})t.  ii,

would  I'each  about  to  base  of  third  abdominal  segment,  two  more  lateral  macro- 
clijeta^  on  each  side;  humeri  and  ]deuraj  cinereous.  Abdomen  rather  ovate, 
vaulted,  clothed  with  short,  black  bristles;  first  segment  somewhat  shortened, 
entirely  black;  other  segments  blackish,  more  or  less  silvery  or  cinereous:  first 
segment  with  a median  marginal  pair  of  macrochfetje  ; second  with  a median 
discal  and  two  median  marginal  pairs;  third  with  a median  discal  pair  and  eight 
long  marginal  macrochajtae  above,  some  shorter  ones  below;  anal  segment  with 
a median  discal  pair,  surmounted  by  a tuft  of  rather  short  macrocliEetae.  Legs 
blackish,  black-hairy,  femora  and  tibiee  slightly  silvery,  latter  with  stout  bristles; 
claws  and  pulvilli  a very  little  elongate.  Wings  a little  longer  than  abdomen, 
moderately  narrow,  grayish  hyaline,  .slightly  pale  tawny  at  base,  with  small  costal 
spine,  third  vein  wdth  a few  spines  at  base;  apical  cell  nearly  closed  in  the  mar- 
gin well  before  ti}>  of  wing;  fourth  vein  bent  at  an  angle,  with  a wrinkle  at 
bend;  hind  cross-vein  nearly  straight,  oblique,  nearer  to  bend  of  fouiTh  vein; 
tegulse  nearly  white,  margins  slightly  yellowish;  halteres  fuscous,  yellowish  at 
base.  Length  6 mm. ; of  wing  4.5  mm. 

Described  from  one  specimen  received  from  Mr.  Chas.  Robertson, 
Carlinville,  111.  This  is  a good,  typical  Taehina  in  the  sense  of 
Schiner;  the  only  difference  being  in  the  nearly  closed  aj)ical  cell. 
Doubtless,  further  specimens  will  show  the  apical  cell  to  be  normally 
more  open. 

Taehina  aletise  Riley,  Can.  Ent.  xi,  162. 

As  the  eyes  are  described  “ thinly  pubescent,”  this  is  not  a Trichina. 
Besides,  the  third  antennal  joint  is  said  to  be  “three  or  four  times 
the  length  of  the  second,”  while  in  Taehina  it  is  at  most  twice  the 
length  of  the  elongate  second.  The  description  is  insufficient  to 
indicate  the  genus.  The  surmise  would  be  that  the  sjiecies  belongs 
in  Exorista. 

Taehina  (Masicera)  armigera  Coquillett,  Ins.  Life  i,  3.32. 

This  species  should  evidently  be  referred  to  Masicera.

about  the  same  width.  Length  51 — mm. ; of  wing  4 — 4S  mm. 

Described  from  one  % and  three  9 specimens  received  from  Mr. 
Cliarles  Robertson,  Carlinville,  111.  Differs  from  Schiner’s  description 
of  }facronychia  as  follows  : Tbe  sides  of  face  are  narrow  and  bare  ; the 
front  is  rather  narrow,  and  of  equal  width  in  both  sexes  ; the  arista 
is  seen  to  be  distinctly  3-jointed  under  a high-power  lens.  It  belongs 
to  Pachyophthahmis  Br.  and  Bgst.  as  separated  by  them  from  Mucro- 
nyc.hia;  and  on  account  of  still  other  differences  beside  those  men- 
tioned above  may  perhaps  better  be  located  in  the  new  genus.  It 
has  the  front  narrower  than  in  Miltogramma.

a prong  on  each  side;  face  and  cheeks  silvery-white,  facial  dei)ressiou  occupying 
one-half  the  width  of  face,  sides  of  face,  therefore,  moderately  wide,  bare;  frontal

mostly  orange,  blackish  at  anus ; first  and  second  segments  without  macrochsetie  ; 
third  .segment  with  about  eight  rather  weak,  marginal  macrochffitje,  the  outer

same  width,  or  slightly  narrower.  Length  6 — 6.5  mm. ; of  wing  4.5 — 5 mm. 

Described  from  two  specimens  from  Mr.  Charles  Robertson,  col- 
lected near  Carlinville,  111.,  which  I am  confident  are  S and  9 t)f 
the  same  sjiecies,  although  both  of  them  have  the  facets  of  the  eye

enlarged  in  front,  and  the  one  with  the  short  claws  seems  to  have  the 
front  slightly  narrower.  The  claws  of  the  other  are  very  elongate. 

1 have  a very  much  smaller  S received  from  Mr.  Robertson  with 
the  above,  which  is  only  4.5  mm.  long.  It  has  the  claws  and  pul- 
villi  elongated  and  very  closely  resembles  the  larger  S , which  is 

6.5  mm  long.  I hesitate  to  describe  it  from  one  specimen,  as  it  seems 
to  differ  only  in  its  very  much  smaller  size  and  darker  abdomen. 
The  abdomen  is  but  slightly  reddish  on  sides  of  second  segment,  rest 
blackish,  silvery  pollinose.  The  arista,  however,  is  not  so  distinctly 
jointed.  It  differs  from  the  following  two  species  in  its  brassy  or 
golden  front,  and  long  flavous  third  antennal  joint.  In  case  it  is 
recognized  from  this  description  and  found  to  be  distinct,  it  may  be 
called  M.  simills. 

The  only  differences  between  the  above  described  Miltogrammas 
and  Schiller’s  generic  description  are  that  the  arista  is  quite  distinctly 
3-jointed,  and  the  third  antennal  joint  is  about  twice  the  length  of 
the  second. 

,^Iiltoj;raiiima  argentif  roiis  a.  sp.  'J, . — Differs  from  M.  flavicornis  a,s 
follows:  Smaller,  without  red  ou  abdomen.  Front  silvery,  iucludiug  vitta,  sides 
darker  iu  some  lights;  only  three  orbital  bristles;  frontal  bristles  not  so  nu- 
merous or  closely  set,  rather  sparse;  anteunse  entirely  dull  blackish,  except 
apical  rim  of  second  joint,  which  is  light  yellowish,  third  joint  scarcely  longer 
than  the  second  ; arista  black,  thickened  only  at  base,  bulbous,  indistinctly 
jointed;  sides  of  face  finely  hairy ; facial  depression  narrow,  scarcely  any  bris- 
tles on  facial  ridges  above  the  vibrissse ; palpi  blackish  or  dark  brown  ; apical 
scutellar  pair  of  macrochsetse  sometimes  not,  but  usually  decussate.  Abdomen 
blackish  or  dark  brown,  light  cinereous  pollinose,  no  distinct  median  vitta ; first 
segment  with  a weak  lateral  macrochgeta  on  the  margin  ; second  with  a lateral 
marginal  one  and  a median  marginal  pair;  third  segment  with  eight  marginal, 
and  anal  segment  with  six  marginal,  as  in  the  above  species.  Claws  and  pulvilli 
elongate.  Tr«(f/s  smaller  ; halteres  flavous.  Length  4 — 5.5  mm.;  of  wing  3.5 — 

4.5  mm. 

Described  from  four  % specimens  received  from  Mr.  Charles 
Robertson,  Carlinville,  111.  One  of  these  specimens  is  much  larger 
(5.5  mm.)  than  the  three  others  (4-4.5  mm.),  and  also  differs  in  hav- 
ing a median  macrochteta  (its  mate  probably  lost)  on  margin  of  first 
abdominal  segment.  The  sides  of  the  face  are  only  very  slightly  hairy. 
It  does  not  otherwise  differ  appreciably.

specimen  from  S.  Illinois  (Robertson)  I believe  should  be  referred 
to  this  species.  It  much  resembles,  but  is  larger  than  M.  argentifrom

Described  from  one  specimen  received  from  Mr.  Chas.  Robertson, 
Carlinville,  111.  This  species  I have  located  temporarily  in  Masicera, 
although  it  does  not  (piite  agree  with  the  characters  of  that  genus. 
The  ajiical  cell  is  opened  only  a little  before  the  wing’s  tip,  and  the 
form  is  rather  narrower  than  is  usual  in  Masicera.  It  apparently 
approaches  Telothyria  v.  d.  Wulp,  but  differs  from  it  by  the  promi- 
nent front,  receding  face  and  distinctly  2-jointed  arista.  Additional 
specimens  will  be  needed  to  decide  its  location.

distance  to  the  oral  margin.  Front  nearly  one-half  the  width  of 
head,  face  wider;  frontal  bristles  descending  in  a single  row  close  to 
facial  ridges  as  far  down  as  lower  border  of  the  eyes;  the  bristles  at

This  genus  can  hardly  be  confused  with  Fhorocera,  to  which  it 
bears  some  resemblance.  The  facial  ridges  are  bare,  but  the  frontal 
bristles  descend  in  a row  just  outside  the  facial  ridges,  and  near 
enough  to  cause  reasonable  doubt  as  to  whether  they  should  be  con- 
sidered cdiate.  Besides  this  distinction,  the  ej  es  aie  bare,  and  the 
apical  cell  is  closed.

Described  from  two  specimens ; a % from  Prof.  J.  M.  Aldrich, 
Brookings,  South  Dakota,  and  a 9 from  Prof  O.  Lugger,  Minn.  (?) 
have  })referred  to  locate  this  species  in  the  genus  Apliria,  although 
in  some  features  it  closely  approaches  OUvierla,  but  differs  from  it 
also  in  others  very  essentially.  The  jiroboscis  is  long,  but  bardly 
bristle-like  and  not  horizontally  protruded.  It  is  straight  and  per- 
pendicularly extended,  of  about  the  same  size  and  length  as  in 
Ocyptera,  but,  unlike  that  genus,  possesses  well-formed  palpi.  The 
eyes  are  extremely  thinly  pubescent  and  the  apical  cell  closed  in  the 
margin,  both  of  which  characters  lead  to  Aphria  in  Schiner’s  table, 
but  are  denied  it  in  his  generic  characterization.  From  Olivi.eria  it 
differs  in  the  receding  (not  almost  perpendicular)  face,  in  the  longer 
and  more  slender  proboscis,  and  in  the  absence  of  discal  macrochpetic 
on  the  abdominal  segments. 

Nemonea  7nasnrius  Wlk.,  N.  clasides  Wlk.,  and  N.  trixoicles  Wlk. 
Mr.  van  der  \Yulp  has  called  attention  to  the  fact  (Biol.  C.-A.  Dipt, 
ii,  47)  that  none  of  these  three  species  belong  in  the  genus  Nemnnv.a, 
since  the  eyes  in  all  of  them  are  bare.

De.scribed  from  one  specimen  received  from  Mr.  Chas.  Robertson, 
Carlinville,  111.  This  species  may  be  looked  upon  as  connecting  the 
two  genera,  Frontina  and  Acroglossa.  It  has  the  arista  nearly  as  in 
Acroglossa,  sometimes  subgen icnlate,  while  it  pos.sesses  the  proboscis 
of  Frontina.  In  general  appearance  it  greatly  resembles  Acroglosm 
hesperidarvm.  The  whole  fourth  abdominal  segment,  however,  is 
reddish  or  orange.  It  further  differs  from  ^4.  hesperidarum  as  fol- 
lows: the  cheeks  do  not  have  bristles,  but  they  are  clothed  with  fine 
bristly  hairs.  The  sides  of  face  are  golden,  and  the  first  abdominal 
segment  bears  a median  j)air  of  macrochaetie  on  its  hind  margin,  as 
well  as  the  second  segment,  though  they  are  weaker.  This  specimen, 
a % (?),  also  has  the  third  antennal  joint  scarcely  three  times  the 
length  of  the  second.

This  new  genus  and  species  is  described  from  California,  and  was 
Itred  from  adults  of  Diabrotica  soror.  It  is  described  as  having  five 
abdominal  segments,  wdiich  would  properly  exclude  it  from  the  Tach- 
inidte  sens,  str.,  and  it  would  fall  in  the  Phaniidte  by  its  other  char- 
acters. The  first  or  basal  segment  is,  however,  as  long  as  the  second, 
and  the  so-called  fifth  segment  is  probably  not  a segment  properly 
speaking,  but  merely  the  more  or  less  concealed  caudal  joint  or  hy- 
poiyygium  to  be  found  in  many  Tachinidte  s.  sti‘.  In  the  OcyjJeridm 
and  Phaniidm,  as  \vell  as  in  the  Phasiidte,  the  first  segment  is  much 
shorter  than  the  second,  and  it  is  at  the  ba.'ie  of  the  abdomen  that 
the  additional  segment  must  be  looked  for.

This  genus  is  readily  distinguislied  from  Siphona,  to  which  it  bears 
a slight  resemblance,  by  the  ))roboscis  not  being  twice  geniculate, 
and  the  arista  with  the  second  joint  not  elongate.  It  is  apparently 
very  near  Spiroglosm  Dol.  of  the  East  Indies. 

Dropanogjlosxia  liiceiis  n.  sp.  % 9- — -Pfile  tawny,  at>clomen  translucent, 
thorax  cinereous.  Eyes  reddish  brown;  front,  face  and  clieeks  pure  silvery 
white;  frontal  vitta  broad  behind,  entirely  covering  the  ocellar  area,  narrowed 
in  front  to  width  of  base  of  antenme,  occupying  one-half  the  width  of  the  front 
in  the  middle,  light  tawny  yellow  in  color;  two  pairs  of  ocellar  bristles,  the  hind 
pair  shorter,  inclined  .slightly  outward,  the  front  pair  inclined  forward  and  out- 
ward ; antennae  same  color  as  frontal  vitta,  light  tawny  yellow,  the  arista  and 
distal  half  or  so  of  third  joint  nearly  black;  first  two  antennal  joints  black 
bristly,  third  very  minutely  pubescent;  proboscis  usually  much  bowed,  basal 
portion  very  light,  slightly  yellowish,  distal  half  or  more  blackish  ; palpi  light 
yellowish  : occiput  cinereous  above,  silvery  white  below,  gray  hairy,  with  a 
fringe  of  alternately  short  and  long  black  hairs  on  the  border  from  the  vertical 
angle  to  the  oral  margin.  Thorax  scutellum  above  light  cinereous,  tinged 
with  tawny  yellow  behind  and  on  scutellum,  covered  with  short  black  hairs  and 
longer  black  bristles  directed  backward  ; a median  posteriorly  divergent  pair  of 
grayish  brown  vittae  becoming  obsolete  near  transverse  suture;  humeri  and 
pleurte  silvery;  two  bristles  below  humeri  directed  outward,  forward  and  up- 
ward ; a vertical  row  of  bristles  directed  posteriorly  in  front  of  base  of  wings, 
three  bristles  on  next  sclerite  below,  front  pair  directed  outward  and  forward, 
and  the  hind  one  outward,  backward  and  upward.  Abdomen  above  very  light 
on  basal  portion,  becoming  more  or  less  brownish  yellow  toward  the  extremity, 
covered  with  short,  appressed,  black  bristles;  segments  two,  three  and  four 
darker  on  hi-ud  margin,  a blackish  median  line  extending  from  base  to  anal  ex- 
tremity ; first  segment  with  some  longer  bristles  on  the  sides,  but  no  macro- 
chfetpe  ; second  with  a lateral  one  and  a median  pair;  third  with  six  above  and 
some  shorter  ones  below ; fourth  segment  with  six  macrochteta; ; venter  cou- 
colorous,  anus  dark.  very  light  yellowish,  finely  black  hairy;  coxae  with 

black  bristles  on  forward  surface  directed  posteriorly;  femora  with  some  weak 
black  bristles,  the  longest  being  on  underside  of  hind  pair;  tibiae  with  some 
shorter  bristles,  tarsi  thickly  covered  with  very  short  black  hairs;  claws  and 
pulvilli  a little  elongate,  about  half  as  long  as  last  tarsal  joint.  Wings  grayish 
hyaline,  wing  veins  light  tawny;  tegulae  whitish,  shining,  margin  narrowly 
opaque,  white ; halteres  white.  Length  4 — 5.5  mm. ; of  wing  3.5  to  nearly  5 mm. 

Described  from  thirty-three  specimens  taken  on  windows  of  Agri- 
cultural College  building,  June  ‘29th  to  July  8th,  Las  Cruces,  N. 
Mex.  Some  specimens  differ  in  the  frontal  vitta  being  of  equal 
width,  wider  than  base  of  antennte  in  front,  occupying  throughout 
one-half  or  more  of  the  frontal  width.  The  probo.scis  is  often  not 
so  much  bowed,  sometimes  nearly  straight.  The  tar.si  of  some  are 
shorter,  particularly  the  distal  joints,  the  claws  and  pulvilli  being 
apparently  a little  less  elongate.  Yet  these  differences  by  no  means 
constantly  acconi[)any  each  other ; I am,  therefore,  uncertain  of  the

sexes.  The  smallest  individuals  have  the  front  and  face  only  one- 
third  the  width  of  the  head,  and,  were  it  not  for  their  short  claws 
and  pulvilli,  I should  consider  them  to  be  the  males.  I believe, 
however,  that  the  males  are  the  larger  ones  with  longer  claws,  wider 
front,  and  more  strongly  bowed  proboscis.

This  ^enus  agrees  in  many  ways,  es|)ecially  in  the  cliaracters  of 
the  head,  with  Hypertrophocera.  But  the  aj)ical  cell  ends  very  little 
before  the  wing’s  tip,  and  is  petiolate  ; the  abdomen  is  narrow  and

Described  from  one  specimen  from  Mr.  Charles  Robertson.  Car- 
linville,  Jll.  This  species  bears  a considerable  resemblance  to  a 
Hyalomyia,  in  the  form  of  the  head,  antennae,  rather  weak  frontal 
bristles,  eyes,  front,  ])roboscis,  palpi,  abdomen,  elongate  tarsal  claws 
and  i)ulvilli,  and  even  in  the  curved  fourth  vein.  It  is  to  be  easily 
distinguished,  however,  by  the  rather  weak  but  distinct  macrocbaette 
of  the  abdomen;  only  four  abdominal  segments;  the  fourth  vein 
not  describing  a perfect  curve  as  in  Hyalomyia,  but  somewhat  an- 
gular ; and  the  large  tegulae.

Bears  a considerable  reseadjlance  to  the  genus  Atrophopoda,  even 
agreeing  with  it  in  the  minute,  atrophied  anterior  claws  and  pulvilli. 
Agrees  with  it  also  in  the  form  of  the  head,  thorax,  abdomen,  legs, 
antenme,  proboscis  and  palpi.  It  diders  from  Atrophopoda  as  fol- 
lows : Eyes  hare ; frontal  bristles  not  extending  below  base  of  an- 
tenme;  arista  rather  long  jiubescent,  almost  plumose  on  median 
portion  ; facial  ridges  bristly  for  some  distance  above  vihrissie  ; cheeks 
not  so  wide.  Abdomen  strongly  conical,  except  a little  narrowed  at 
base,  not  in  the  least  flattened  or  vaulted,  macrochietpe  entirely  mar- 
ginal. Wings  without  costal  spine ; apical  cell  rather  long  petiolate, 
ending  at  a considerable  distance  before  the  tip  of  the  wing;  fourth 
vein  at  bend  strong  angular,  with  a distinct  stump  of  a vein;  hind 
cross-vein  nearly  straight.  Type,  V-  atropliopodoides  n.  sp. 

Named  in  honor  of  Mr.  F.  M.  van  der  Wnlp,  of  The  Hague,

lights;  cheeks  silvery  white  posteriorly,  more  or  less  hlackish  anteriorly  ; frontal 
vitta,  antennte  and  arista  hlack  ; proboscis  mostly  black,  labella  brown,  hairy;  palpi 
light  slate  color;  occiput  cinereous,  gray  hairy,  with  fringe  of  hlack  bristles  on  or- 
bital margins.  Thorax  and  scutelliim  bristly,  sparsely  hairy,  silvery  white,  with 
broad,  median,  uninterrupted  black  vittie  reaching  to  apex  of  scutellum  ; humeri 
two  and  pleurte  silvery.  Abdomen  deep  orange-red,  bases  of  second  to  fourth 
segments  rather  narrowly  silvery  white  ]iollinose,  the  whole  covered  with  short, 
appressed  black  bristles;  first  and  second  segments  with  only  a median  pair  of 
macrochaetse ; third  and  fourth  segments  each  with  eight  erect  macrochaetae,  and 
some  shorter  macrochaeta-like  bristles  on  the  concolorous  venter.  Legs  black, 
black  hairy,  silvery  and  bristly  except  tarsi  and  front  tibiae;  claws  and  pulvilii 
not  elongate.  Wings  obscure  grayish  hyaline,  costal  border  and  borders  of  veins 
fuscous;  tegulae  pure  white,  halteres  fuscous  or  brownish.  Length  7.5 — 8.5  mm. ; 
of  wing  6 — 6.5  mm. 

Described  from  two  specimens  taken  July  20th.  Las  Caaices,  X. 
Mex.  This  is  a beautiful  and  striking  species.  Although  the  frontal 
bristles  do  not  descend  on  the  face  and  the  arista  is  short  feathered, 
this  species  seems  to  claim  close  I’elationship  with  Atrophopoda.  The 
front  claws  and  pulvilii  in  both  are  minute,  and  the  general  facies  is 
strikingly  the  same.  It  is  possible  that  a greater  amount  of  mate- 
rial in  this  sub-group  may  demonstrate  the  affinities  of  one  or  both 
genera  with  the  Dexiidse. 

Genus  Arthrochceta  Br.  and  Bgst.,  Zweifl.  kais.  Mus.  W.  iv,  134. 
This  genus  is  not  sufficiently  characterized  to  stand.  It  is  prefixed 
to  a species  called  by  the  authors  A.  demoticoides,  from  Columbia, 
the  short  specific  characterization  of  which  at  the  end  of  the  woi’k 
throws  no  light  on  the  matter. 

Note  on  the  Dexiid  genus  Uromijia  Rob.-Desv. — The  writer  has 
published  a note  on  this  genus  (Proc.  Ent.  Soc.  Washington,  ii,  100) 
calling  attention  to  the  fact  that  the  name  was  first  employed  by 
Robinean-Desvoidy,  and  afterwards  applied  by  IMeigen,  or  a name 
so  nearly  like  it  as  to  be  misleading  and  confusing,  to  a Phaniid.  In 
order  to  avoid  confusion  in  the  use  of  the  word,  I ])ropose  for  Meigen’s 
genus  the  name  Neouromyia. 

Note  on  the  Dexiid  genus  Tropidoniyia  Br.  and  Bgst. — Brauer 
and  V.  Bergenstamm  (Zweifl.  kais.  INIus.  W.  iv,  119,  1889),  have 
erected  a genus  which  they  called  Trop>idomyia,  for  a Dexiid  from 
Syria.  The  name  is  preoccupied;  Dr.  Williston  applied  it  to  a 
South  American  Conopid,  which  he  described  in  “Can.  Ent.,”  Jan- 
uary, 1888.  Brauer’s  genus  must,  therefore,  be  given  another  name, 
and  I propose  that  of  Neotropidomyia.
